Description

[Technical Field]

[0001] The present invention relates to a roll film storage management system that stores and manages multiple roll films used in packaging machines, an automatic roll film loading system that automatically loads roll films stored by the roll film storage management system into packaging machines, and an automatic roll film transport and storage system that automatically transports roll film removed from packaging machines and unused roll film and stores them in the roll film storage management system. [Background technology]

[0002] In packaging machines such as vertical pillow packaging machines, horizontal pillow packaging machines, wrapping packaging machines, and overwrap packaging machines, packages are produced by continuously unwinding film (packaging material) from a take-up film attached to a shaft that supports the take-up film in the packaging material supply section, but when the take-up film (old take-up film) runs out, a new take-up film (new take-up film) is attached to the shaft and production of packages continues. The changeover from the old rolled film to the new rolled film in this packaging material supply section is usually done manually by an operator, but with the aim of automating packaging machines, devices and systems have been proposed that store and manage the rolled film and automatically switch from the old rolled film to the new rolled film.

[0003] For example, Patent Document 1 (JP 2006-199489 A) discloses a bag-making and packaging machine 3, a second control unit 30, a transport device 51 consisting of a belt conveyor, and a stock unit 52 in which a plurality of film rolls 9 are supported and stored by stock support units 62. The film rolls 9 are each fitted with an ID tag 9d that stores data relating to the product corresponding to each film roll 9, data on the width and material of the film F, the date and time the film was delivered to the stock unit 52, the remaining amount of film F, and other data. The second control unit 30 controls a reading unit 61 to read the information stored in the ID tag 9d. 2b, individual information for each film roll 9 (corresponding product, film width, material, delivery date, remaining amount of film) is received, and based on this individual information, a film roll 9 corresponding to the bag-making packaging machine 3 to be loaded is selected. The selected film roll 9 is transported to the side of the bag-making packaging machine 3 by a conveying device 51, and the film roll 9 is automatically loaded into each bag-making packaging machine 3 via a first control unit 20.

[0004] However, in the bag-making and packaging system 50 of Patent Document 1, an ID tag 9d is attached to the film roll 9, and the data stored in this ID tag 9d is read by a reading unit 62b attached to the third shaft 62a of the stock support unit 62 that supports the film roll 9 in the stock section 52. The data read by this reading unit 62b is received by the second control unit 30 and used to select the film roll 9. Therefore, if the third shaft 62a of the stock support unit 62 that supports the film roll 9 in the stock section 52 is not present, that is, if the film roll 9 is stored without being supported by a shaft, there is no third shaft 62a to which the reading unit 62b is attached, and the data in the ID tag 9d cannot be read. As a result, the second control unit 30 is unable to select the film roll 9, and the bag-making and packaging system 50 cannot be applied. Furthermore, the bag-making and packaging system 50 of Patent Document 1 requires a means for recording individual information on the ID tag 9d attached to the film roll 9, which requires equipment for this purpose (e.g., an ID tag data writing device) and the work of writing data to the ID tag 9d. Furthermore, in the bag making and packaging system 50 of Patent Document 1, the consistency between the data stored in the ID tag 9d and the information on the film roll 9 to which the ID tag 9d is attached (corresponding product, film width, material, delivery date, remaining amount of film) is not verified, and if the data on the ID tag 9d and the information on the film roll 9 differ, problems may arise such as the incorrect film roll 9 being loaded into the packaging machine. In particular, it is difficult to accurately manage the remaining amount of film, and the remaining amount of film recorded on the ID tag 9d often differs from the actual remaining amount of film (the film on the roll from which the film has been consumed).

[0005] Next, Patent Document 2 (JP Patent Publication No. 10-235853) discloses an inventory management system for reel parts (small parts wound on reels used by automatic machines that mount parts) that consists of a processing device that processes inventory management requests, a storage device that stores inventory management programs and management information, and input / output peripheral devices, and that generates management information for reel parts based on inventory registration requirements such as item, quantity, lot number, manufacturer, etc. and shipping requirements such as item, quantity, etc. that are input into the system, and performs an automatic search to identify reel parts that satisfy the shipping requirements and to identify their storage locations, and automatically checks whether the shipped items are correct. In the reel part inventory management system of Patent Document 2, a writable and readable data carrier is attached to the reel, which is the exterior packaging of the reel part, and management information for the reel part is recorded on this data carrier, and the reel part is stored in a designated storage location.When the reel part is shipped, the data on the data carrier attached to the reel part is read, and the authenticity of the reel part to be shipped is automatically confirmed based on the read data. In this case, it is conceivable to apply the reel parts inventory management system of Patent Document 2 to the management of the rolled film used in the packaging machine. However, the winding film used in the packaging machine does not have the reel (winding frame) that the reel component of Patent Document 3 has, and it is not possible to attach a data carrier to the winding film. If the data carrier were attached directly to the reel film, the film unwound from the reel film would become the packaging material for the packaged item, so the data carrier would need to be peeled off from the new reel film before the new reel film is attached to the packaging machine.Furthermore, when the old reel film is removed from the packaging machine for storage, the data carrier would need to be attached to the old reel film again, making handling of the data carrier extremely cumbersome.

[0006] Furthermore, Patent Document 3 (JP Patent Publication No. 9-315688A) discloses a winding roll storage device for storing winding rolls in which plastic film is wound in a roll shape around a winding shaft that is longer than the width of the film, and the device includes a pair of rollers that support the undersides of both ends of the winding shaft, and a drive device that rotates the rollers so as to repeat an operation consisting of forward rotation, stop, reverse rotation, and stop, in sequence, for each predetermined time. However, in the winding roll storage device of Patent Document 3, the undersides of both ends of the winding shaft that protrude from the roll end face of the winding roll are supported by a pair of rollers, and the winding roll is rotated by rotating the rollers, so it cannot be used to store wound film whose paper tube does not protrude from the end face. Furthermore, the winding roll storage device of Patent Document 4 simply stores winding rolls, and does not store various winding films used in multiple packaging machines in food factories, etc., and does not manage information identifying each winding film (such as the product for which the winding film is used, the diameter, width, and material of the winding film).

[0007] Furthermore, Patent Document 4 (JP 2011-236043 A) discloses a management method for film rolls 10 in which a film 14 is wound around a cardboard tube 12, in which the amount of deflection at the center in the longitudinal direction of the film rolls 10 stored in a storage location is measured, and it is determined whether the amount of deflection of the film rolls 10 is equal to or less than a preset allowable amount; if multiple film rolls 10 are stored in the storage location, the film rolls 10 whose amount of deflection is equal to or less than the allowable amount and closest to the allowable amount are removed from the storage location in order; and for film rolls 10 whose amount of deflection exceeds the allowable amount, the wound film 14 is rewound onto another cardboard tube. However, the film roll management method in Patent Document 4 only measures and manages the amount of deflection of the film roll 10, and does not involve storing a large number of rolled films in a food factory or the like, managing information identifying each rolled film (management information such as the product for which the rolled film is used, the diameter, width, and material of the rolled film), or checking the consistency between the management information and the rolled film.

This forms the framework of the winding film stocker 10, and a space is formed between the underside of the base frame 11a and the floor surface FL so that the front part of the traveling base (described later) of the unmanned transport robot 40 can fit inside.

Mounted inside the lower front horizontal frame 12a or rear horizontal frame 12b are mountable table motors that rotate each of the mounting rollers 16a1, 16b1 to 16a5, 16b5 (for example, mountable table motor MT1 that rotates mounting rollers 16a1, 16b1 is mounted near the axes of mounting rollers 16a1, 16b1, and mountable table motor MT2 that rotates mounting rollers 16a2, 16b2 is mounted near the axes of mounting rollers 16a2, 16b2), and mounted inside the upper front horizontal frame 13a or rear horizontal frame 13b are mountable table motors that rotate each of the mounting rollers 16a6, 16b6 to 16a10, 16b10 (for example, mountable table motor MT10 that rotates mounting rollers 16a10, 16b10 is mounted near the axes of mounting rollers 16a10, 16b10).

[0032] These stock tables ST1 to ST10 serve as the loading tables of the present invention, and the peripheral surface of the rolled film is placed on each of the loading rollers 16a1, 16b1 to 16a10, 16b10. As shown in the figure, a rolled film M101 is placed on stock stand ST1 (placement rollers 16a1, 16b1), a rolled film M102 is placed on stock stand ST2 (placement rollers 16a2, 16b2), a rolled film M103 is placed on stock stand ST3 (placement rollers 16a3, 16b3), a rolled film M111 is placed on stock stand ST4 (placement rollers 16a4, 16b4), and a rolled film M111 is placed on stock stand ST5 (placement rollers 16a1, 16b1). First, the rolled film M201 is placed on stock stand ST6 (loading rollers 16a6, 16b6), the rolled film M202 is placed on stock stand ST7 (loading rollers 16a7, 16b7), the rolled film M203 is placed on stock stand ST8 (loading rollers 16a8, 16b8), the rolled film M211 is placed on stock stand ST9 (loading rollers 16a9, 16b9), and no rolled film is placed on stock stand ST10 (loading rollers 16a10, 16b10). The rolled film placed on stock tables ST1 to ST10 (including the case where no rolled film is placed thereon) is managed in a rolled film management information table 32a (described later) of the overall management computer 30.

[0033] Here, sensor units SU1 to SU10 are installed on the top of the stock tables ST1 to ST10, respectively. Figure 7(a) is an oblique view of sensor unit SU1, Figure 7(b) is a front view of sensor unit SU1, Figure 7(c) is a plan view of sensor unit SU1, Figure 7(d) is a bottom view of sensor unit SU1, Figure 7(e) is a left side view of sensor unit SU1, and Figure 7(f) is a right side view of sensor unit SU1. In the figures, the front horizontal frame 13a and the rear horizontal frame 13b are represented by virtual dashed double-dashed lines. As shown in Figure 7, the sensor unit SU1 comprises fixed blocks 18a1 and 18b1 arranged at a distance from each other, a rod 18c1 attached to the fixed blocks 18a1 and 18b1, a support block 18d1 movably inserted into the rod 18c1, and a support plate 18e1 attached to the lower right side of the support block 18d1, with a first distance sensor SA1 attached to the underside of the support block 18d1, a barcode reader BR1 attached to the underside of the support plate 18e1, and an indicator lamp Lp1 attached to the upper front of the front fixed block 18a1. The first distance sensor SA1 is a laser distance sensor or an ultrasonic sensor, the barcode reader BR1 is a barcode reader that reads one-dimensional or two-dimensional barcodes printed on the packaging material of the package, and the indicator lamp is a multi-color (e.g., three-color) LED lamp. The sensor unit SU1 is installed on the top of the stock table ST1. Specifically, fixed block 18a1 is fixed to the underside of front horizontal frame 13a, fixed block 18b1 is fixed to the underside of rear horizontal frame 13b so that rod 18c1 is positioned at the top middle (center) of loading rollers 16a1 and 16b1, and support block 18d1, which is movable along rod 18c1, is fixed in a position almost directly above the barcode printed on the rolled film loaded on stock table ST1 (loading rollers 16a1 and 16b1). As a result, the top (upper end) of the circumferential surface of the rolled film placed on the stock table ST1 is positioned directly below the first distance sensor SA1 attached to the underside of the support block 18d1, and the first distance sensor SA1 measures the distance from the first distance sensor SA1 to the top (upper end) of the circumferential surface of the rolled film. In addition, the barcode printed on the rolled film placed on the stock table ST1 is located below the barcode reader BR1 on the underside of the support plate 18e1, and the barcode printed on the rolled film is read by the barcode reader BR1. Furthermore, the indicator lamp Lp1 indicates in different colors whether or not a roll of film is placed on the stock table ST1 and the verification result of the roll of film placed on the stock table ST1 (details will be described later).

[0034] The other sensor units SU2 to SU10 have the same structure as sensor unit SU1, and each comprises fixed blocks 18a2 to 18a10, 18b2 to 18b10, rods 18c2 to 18c10, support blocks 18d2 to 18d10, and support plates 18e2 to 18e10. First distance sensors SA2 to SA10 are attached to the support blocks 18d2 to 18d10, barcode readers BR2 to BR10 are attached to the undersides of the support plates 18e2 to 18e10, and indicator lamps Lp2 to Lp10 are attached to the upper front surfaces of the fixed blocks 18a2 to 18a10. The sensor units SU2 to SU10 are installed above the stock tables ST2 to ST10, respectively. Specifically, fixed blocks 18a2 to 18a5 are fixed to the underside of the front horizontal frame 13a, and fixed blocks 18b2 to 18b5 are fixed to the underside of the rear horizontal frame 13b so that the lower rods 18c2 to 18c5 are positioned above the middle (center) of the loading rollers 16a2 to 16a5, 16b2 to 16b5, fixed blocks 18a6 to 18a10 are fixed to the underside of the front upper plate 17a, and fixed blocks 18b6 to 18b10 are fixed to the underside of the rear upper plate 17b so that the upper rods 18c6 to 18c10 are positioned above the middle (center) of the loading rollers 16a6 to 16a10, 16b6 to 16b10, and each support block 18d2 to 18d10 is fixed in a position approximately directly above the barcode printed on the rolled film placed on each stock table ST2 to ST10. As a result, the top (upper end) of the circumferential surface of the rolled film placed on the stock tables ST2 to ST10 is positioned directly below the first distance sensors SA2 to SA10 attached to the underside of each support block 18d2 to 18d10, and the first distance sensors SA2 to SA10 measure the distance from the first distance sensors SA2 to SA10 to the top (upper end) of the circumferential surface of the rolled film placed on the stock tables ST2 to ST10. In addition, on the underside of support plates 18e2 to 18e10, below barcode readers BR2 to BR10, barcodes printed on the rolled film placed on stock tables ST2 to ST10 are positioned, and barcode readers BR2 to BR10 read the barcodes printed on the rolled film placed on stock tables ST2 to ST10.

[0035] Next, second distance sensors SB1 to SB5 are installed on the upper surface of the lower front horizontal frame 12a of the winding film stocker 10 at intermediate (center) positions between the loading rollers 16a1, 16b1 to 16a5, 16b5 of the stock tables ST1 to ST5. Additionally, second distance sensors SB6 to SB10 are installed on the upper surface of the upper front horizontal frame 13a of the take-up film stocker 10 at intermediate (center) positions between the loading rollers 16a6, 16b6 to 16a10, and 16b10 of the stock tables ST6 to ST10. The second distance sensors SB1 to SB10 are laser distance sensors or ultrasonic sensors, like the first distance sensors SA1 to SA10. Then, the second distance sensors SB1 to SB10 measure the distance from each of the second distance sensors SB1 to SB10 to the side surface on the front side of each of the rolled films placed on the stock tables ST1 to ST10. In this case, the second distance sensors SB1 to SB5 are installed at a position higher than the upper ends of the loading rollers 16a1, 16b1 to 16a5, and 16b5, and the second distance sensors SB6 to SB10 are installed at a position higher than the upper ends of the loading rollers 16a6, 16b6 to 16a10, and 16b10.Therefore, regardless of the winding diameter of the rolled film placed on the stock tables ST1 to ST10, the laser light or ultrasonic waves emitted from the second distance sensors SB1 to SB10 irradiate the side of the rolled film, and the second distance sensors SB1 to SB10 can measure the distance to the side of each rolled film on the stock tables ST1 to ST10. Alternatively, the second distance sensors SB1 to SB5 may be attached to the upper surface of the rear horizontal frame 12b on the lower side of the rolled film stocker 10, and the second distance sensors SB6 to SB10 may be attached to the upper surface of the rear horizontal frame 1bb on the upper side of the rolled film stocker 10, to measure the distance from each of the second distance sensors SB1 to SB10 to the rear side of each rolled film placed on the stock tables ST1 to ST10.

[0036] [Winding film stocker control device] The rewind film stocker 10 is provided with a rewind film stocker control device 20 that controls its operation, etc., and this rewind film stocker control device 20 includes a rewind diameter calculation unit 21, a film width calculation unit 22, a barcode reader control unit 23, a motor operation command control unit 24, and a lamp display control unit (not shown). The winding diameter calculation unit 21 calculates the winding diameter of the winding film based on the distance (first distance information) measured by the first distance sensors SA1 to SA10 to the top of the peripheral surface of the winding film placed on the stock tables ST1 to ST10. FIG. 8 is an explanatory diagram illustrating the process by which winding diameter calculation unit 21 calculates the winding diameter of winding film M101 placed on stock table ST1 based on the distance measured by first distance sensor SA1. On the stock table ST1, the loading roller 16a1 and the loading roller 16b1 are installed at the same height, and if D is half the distance between the centers of the two loading rollers, r is the radius of the two loading rollers, and H is the height from the center of the two loading rollers to the first distance sensor SA1, then D, r, and H are fixed values. Now, let R be the radius of the rolled film M101, h be the distance measured by first distance sensor SA1 from first distance sensor SA1 to the top of the circumferential surface of the rolled film M101, h0 be the height from the center of loading rollers 16a1 and 16b1 to the center of the rolled film M101, and θ be the angle formed by the line connecting the center of the rolled film M101 and loading roller 16a1 and the line connecting the centers of loading rollers 16a1 and 16b1. The relationship between radius R, distance h, height h0, and angle θ is as follows: R+h+h0=H, h0=(R+r)sinθ, tanθ=h0 / D In this case, since D, r, and H are fixed values, R and h are uniquely determined. As a result, winding diameter calculation unit 21 calculates winding diameter 2R of winding film M101 based on distance h measured by first distance sensor SA1. Similarly, winding diameter calculation unit 21 calculates the winding diameter of the rolled film placed on stock tables ST2 to ST10 based on the distances measured by the other first distance sensors SA2 to SA10. The information on the winding diameter calculated by the winding diameter calculation unit 21 is sent to a transmitting / receiving unit (not shown) of the winding film stocker control device 20, and is then transmitted from the transmitting / receiving unit to the control computer 30 via the communication line CL5.

[0037] The film width calculation unit 22 calculates the film width of the rolled film based on the distance (second distance information) measured by the second distance sensors SB1 to SB10 to the front side of the rolled film placed on the stock tables ST1 to ST10. Figure 9 is an explanatory diagram that explains the process by which the film width calculation unit 22 calculates the film width of the rolled film M101 placed on the stock table ST1 based on the distance measured by the second distance sensor SB1, and in the figure, CL is the center line in the Y direction of the space formed by the facing surfaces of the front horizontal frame 12a and the rear horizontal frame 12b. On the stock stand ST1, the rolled film M101 is placed on the stock stand ST1 (loading rollers 16a1, 16b1) so that its center in the axial direction (Y direction) coincides with the center line CL, and if the distance from the tip surface of the second distance sensor SB1 installed on the upper surface of the front horizontal frame 12a to the center line CL is W, W is a fixed value. Now, if the film width of the rolled film M101 is 2L and the distance measured by the second distance sensor SB1 to the side surface on the front side of the rolled film M101 is d, then 2L=2(Wd). Film width calculation unit 22 then calculates film width 2L of rolled film M101 based on distance d measured by second distance sensor SB1. Similarly, film width calculation unit 22 calculates the film width of the rolled film placed on stock tables ST2 to ST10 based on the distances measured by the other second distance sensors SB2 to SB10. The film width information calculated by film width calculation unit 22 is sent to a transmitting / receiving unit (not shown) of take-up film stocker control device 20, and is then transmitted from this transmitting / receiving unit to control computer 30 via communication line CL5.

[0038] The calculation of the winding diameter and film width of the rolled film placed on the stock tables ST1 to ST10 is not limited to calculation based on the distance measured by one distance sensor as described above, but may also be calculation based on the distance measured by two distance sensors. Figure 10(a) is an explanatory diagram of an example of calculating the winding diameter based on the distance measured by two first distance sensors, and Figure 10(b) is an explanatory diagram of an example of calculating the film width based on the distance measured by two second distance sensors, where SA1' is the first distance sensor and SB1' is the second distance sensor. In the example shown in Figure 10(a), in addition to the first distance sensor SA1 located directly above the top (upper end) of the circumferential surface of the rolled film M101 on the stock table ST1, a first distance sensor SA1' is installed at a position below the lower end of the circumferential surface of the rolled film M101. That is, the first distance sensor SA1 and the first distance sensor SA1' sandwich the rolled film M101, and the first distance sensor SA1' is installed directly below the first distance sensor SA1 so that the line connecting the center of the first distance sensor SA1 and the center of the first distance sensor SA1' passes through the central axis of the rolled film M101. Now, let H' be the height from the tip surface of first distance sensor SA1' to the tip surface of first distance sensor SA1, h be the distance measured by first distance sensor SA1 from first distance sensor SA1 to the top (upper end) of the circumferential surface of the rolled film M101, and h' be the distance measured by first distance sensor SA1' from first distance sensor SA1' to the lower end of the circumferential surface of the rolled film M101. Then, the roll diameter 2R of the rolled film M101 is 2R = H' - (h + h'). Height H' is a fixed value, and winding diameter calculation unit 21 calculates winding diameter 2R of winding film M101 based on distance h measured by first distance sensor SA1 and distance h' measured by first distance sensor SA1'. By using two first distance sensors SA1 and SA1' in this manner, the effects of depressions on the contact surface of the rolled film M101 with the loading rollers 16a1 and 16b1 and deflection of the loading rollers 16a1 and 16b1 that occur when the rolled film M101 is placed on the stock table ST1 are eliminated, and the winding diameter 2R of the rolled film M101 can be calculated more accurately than when one first distance sensor SA1 is used. Similarly, for the rolled films placed on the other stock tables ST2 to ST10, in addition to the first distance sensors SA2 to SA10, a first distance sensor identical to the first distance sensor SA1' is installed, and the roll diameter is calculated based on the distance measured by the two first distance sensors.

[0039] In the example shown in Figure 10(b), in addition to the second distance sensor SB1 installed on the upper surface of the front horizontal frame 12a, a second distance sensor SB1' is installed on the upper surface of the rear horizontal frame 12b at a position opposite the second distance sensor SB1. Now, let W' be the distance from the tip surface of the second distance sensor SB1 to the tip surface of the second distance sensor SB1', d be the distance measured by the second distance sensor SB1 from the second distance sensor SB1 to the front side of the rolled film M101, and d' be the distance measured by the second distance sensor SB1' from the second distance sensor SB1' to the back side of the rolled film M101. Then, the film width 2L of the rolled film M101 is 2L = W' - (d + d'). The distance W' is a fixed value, and film width calculation unit 22 calculates film width 2L of rolled film M101 based on the distance d measured by second distance sensor SB1 and the distance d' measured by second distance sensor SB1'. By using two second distance sensors SB1 and SB1' in this manner, the film width of the rolled film M101 can be calculated even if the rolled film M101 is placed on the stock table ST1 with its center in the axial direction (Y direction) offset from the center line CL. Similarly, for the rolled films placed on the other stock tables ST2 to ST10, in addition to the second distance sensors SB2 to SB10, a second distance sensor identical to second distance sensor SB1' is installed, and the film width is calculated based on the distance measured by the two second distance sensors.

[0040] The barcode reader control unit 23 controls the reading operations of the barcode readers BR1 to BR10 attached to the sensor units SU1 to SU10. The motor operation command control section 24 also controls the rotation of the loading rollers 16a1, 16b1 to 16a10, 16b10 by the loading table motors attached to the inside of the front horizontal frames 12a, 13a or the rear horizontal frames 12b, 13b. For example, when the barcode information printed on the rolled film M101 placed on the stock table ST1 is read by the barcode reader BR1, the motor operation command control unit 24 first issues an operation command to the mount motor MT1, causing the mount motor MT1 to rotate, which in turn causes the mount rollers 16a1 and 16b1 to rotate and the rolled film M101 to rotate at a low speed. Next, the barcode reader control unit 23 issues a reading command to the barcode reader BR1, and when the barcode printed on the rotating rolled film M101 comes within the reading range of the barcode reader BR1, the barcode reader BR1 reads the information in the barcode. This allows the barcode reader BR1 to reliably read the information in the barcode printed on the rolled film M101. On the other stock tables ST2 to ST10, the loading table motor rotates each loading roller 16a2, 16b2 to 16a10, 16b10, causing the rolled film placed on top of it to rotate at a low speed, and the barcode readers BR2 to BR10 read the barcode information printed on the rolled film. Then, the barcode reader control unit 23 sends the barcode information read by each barcode reader BR1 to BR10 to a transceiver unit (not shown) of the winding film stocker control device 20, and the barcode information is transmitted from this transceiver unit to the general computer 30 via communication line CL5.

[0041] The lamp display control unit controls the timing and color of each of the display lamps Lp1 to Lp10. In this case, a detection sensor (not shown) is attached to each stock table to detect when a roll of film has been placed on it. For example, when the detection sensor detects that a roll of film M101 has been placed on the stock table ST1, the lamp display control unit controls the display lamp Lp1 to light up blue based on the detection signal. In addition, when verification (described later) of the winding diameter, film width, product information, etc. of the rolled film placed on each stock table is performed, the lamp display control unit controls the display lamp to light up in a color corresponding to the verification result. For example, the winding diameter, film width, and product information of the rolled film M101 placed on the stock table ST1 are verified, and if the verification results are all correct, the lamp display control unit controls the indicator lamp Lp1 to light green, and if the verification results of any of the winding diameter, film width, and product information are incorrect, the lamp display control unit controls the indicator lamp Lp1 to light red.

[0043] The film (packaging material) supply unit 111 includes a rolled film support device and a paper splicing table (not shown). The take-up film support device is made up of a shaft support arm 111a, support shafts 111b1 and 111b2, and the like. The shaft support arm 111a has its center supported by an arm support stand (not shown) via a rotating shaft (not shown), and support shafts 111b1 and 111b2 are supported at both longitudinal ends of the shaft support arm 111a, and the support shafts 111b1 and 111b2 are rotated by servo motors (not shown). In the rolled film support device, the rolled film MF1 wound around a cardboard tube (not shown) is attached to one support shaft 111b1, which is rotated by a servo motor, and the film Fi that will become the packaging material is unwound from the rolled film MF1. Before the rolled film MF1 on support shaft 111b1 runs out, a new rolled film is attached to the other support shaft 111b2. Just before the rolled film MF1 on support shaft 111b1 runs out, the shaft support arm 111a rotates, and support shaft 111b2 rotates and moves to the position of support shaft 111b1. When the rolled film MF1 on support 111b1 runs out, a splice is performed on the splicing table to join the old rolled film MF1 (the film that was being unwound from support shaft 111b1) and the new rolled film (the film being unwound from support shaft 111b2).

[0044] The tension adjustment unit 112 is composed of a pair of rotating arms 112a, a dancer roller rotatably held by the rotating arms 112a, a fixed roller 112b, a rotating rod, a rotating mechanism (not shown) for the rotating arms 112a, etc., and a rotary encoder (not shown) is attached to the rotating rod. The rotation mechanism of the rotating arm 112a rotates the rotating arm 112a to lift the dancer roller to its upper limit position, and is composed of, for example, an air cylinder and a stopper. The rotation arm 112a is rotated by the extension and contraction of the piston rod of the air cylinder, and the rotation arm 112a is stopped when it hits the stopper. In the tension adjusting unit 112, when the tension of the film Fi stretched over the dancer roller and fixed roller 112b increases, the tip of the rotating arm 112a is lifted, and when the tension of the film Fi decreases, the tip of the rotating arm 112a is lowered, and the rotating arm 112a rotates about the rotating rod in response to the change in tension of the film Fi, changing the tilt angle of the rotating arm 112a. This change (displacement) in the tilt angle of the rotating arm 112a is detected by a rotary encoder as the displacement of the dancer roller, and the tension of the film Fi is controlled.

The winding film support device is made up of a shaft support frame 311a, support shafts 311b1 and 311b2, and the like. Unlike the shaft support arm 111a of the packaging machine 100, which is supported by an arm support stand and rotates, the shaft support frame 311a is fixed to a machine frame (not shown) and does not rotate. Support shafts 311b1 and 311b2 are supported at both longitudinal ends of the shaft support frame 311a, and the support shafts 311b1 and 311b2 are rotated by servo motors (not shown). In the rolled film support device, rolled film MF3 wound around a cardboard tube (not shown) is attached to one support shaft 311b1, which is rotated by a servo motor, and film Fi, which will become packaging material, is unwound from the rolled film MF3. Before the rolled film MF3 on support shaft 311b1 runs out, a new rolled film is attached to the other support shaft 311b2. When the rolled film MF3 on support shaft 311b1 runs out, a film splicing device splices together the old rolled film MF3 (the film that was being unwound from support shaft 311b1) and the new rolled film (the film being unwound from support shaft 311b2). The packaging material feed section 312 clamps the packaging material Fi between a drive roller 312a and a pressure roller 312b, rotates the drive roller 312a using a motor (not shown), feeds out the packaging material Fi by a certain length, and guides the packaging material Fi from above to the tube making section 314 using a tension roller 312d attached to a tension arm 312c. The date printing device 312e prints the date (such as the date of manufacture) on the packaging material Fi.

[0048] The packaged product supply section 313 places packaged products (products) on a belt conveyor 313a and fills the packaged products into a tubular packaging material TF. The tube forming section 314 forms (forms) the packaging material Fi into a tubular packaging material TF using a tube former 314a. The film pulling section 315 pinches the overlapping ends of the tubular packaging material TF between the drive roller 315a and the pressure roller 315b, and rotates the drive roller 315a using a motor (not shown), feeding out a fixed length of the tubular packaging material TF. Center seal section 316 sandwiches the ends of the overlapped tubular packaging material TF between center seal blocks 316a, 316b heated by a heater (not shown), and applies a center seal cs to the tubular packaging material TF. In this case, the center seal cs will be positioned below the packaged product. The center seal cs of the tubular packaging material TF is sandwiched between the setting rollers 317a and 317b of the setting unit 317, and one of the setting rollers 317a is rotated by a motor (not shown) to apply a setting to the center seal cs. The end seal and cutting section 318 uses end seal blocks 318a and 318b heated by a heater (not shown) to clamp the tip of the tubular packaging material TF and apply an end seal to form an end seal portion es, and then cuts the center of the end seal portion es to produce a package Pc filled with the packaged product. In this way, in the packaging machine main body 310, the film (packaging material) supply section 311 and packaging material feed section 312 are located above the tube forming section 314, and the packaged product is wrapped from above with the packaging material Fi to produce the package Pc.

FIG. 18 is an explanatory diagram illustrating the configuration of the roll film management information table 32a. In the rolled film information table 32a, "stock table number," "rolled film number," "product number," "product name," "roll diameter," and "film width" are registered in association with each other. "Stock table No." is a number assigned to the stock table (mounting table) on which the rolled film is placed in the rolled film stocker 10, and serves as information for identifying the stock table. "Rolled film No." is a number given to the rolled film stored on the stock table of the rolled film stocker 10, and serves as information for identifying each rolled film. The "product number" is a number that identifies the product (packaging) produced using that rolled film, and the "product name" is the name given to the product (packaging) corresponding to the "product number." The "product number" and "product name" constitute the product information. "Reel diameter" refers to the reel diameter (diameter) of the reeled film, and "film width" refers to the width of the film unwound from the reeled film. Thus, in the roll film information table 32a, roll film management information (roll film number, product name, product number, roll diameter, film width) of the roll film stored in the roll film stocker 10 is registered in correspondence with the stock rack number. For example, a roll film numbered "101" is placed on a stock rack numbered "01," and this roll film is used to produce a package with the product number "01" and product name "aaaa," and the roll diameter is 400 mm and the film width is 600 mm. Furthermore, since no rolled film is stored in stock racks with stock rack numbers "05" and "10," no rolled film management information is registered therein.

[0059] The management control unit 31 includes an incoming roll film management information acquisition unit 31a, an outgoing roll film specific information acquisition unit 31b, a roll film management information update unit 31c, a roll film management information verification unit 31d, a packaging machine designation unit 31e, a roll film selection unit 31f, and a stock table selection unit 31g. The incoming roll film management information acquisition unit 31a acquires incoming roll film management information, which is roll film management information (roll film number, product name, roll diameter, and film width information) regarding the incoming roll film (remaining roll film) that is removed from the packaging machine 100-400 and stored in the roll film stocker 10, based on the roll film removal request information generation unit of each of the operation panels 130-430 of the packaging machine 100-400 and transmitted from the operation panels 130-430. In addition, the incoming roll film management information acquisition unit 31a acquires incoming roll film management information, which is roll film management information regarding the incoming roll film (unused roll film) that is moved from the unused roll film storage device 60 and stored in the roll film stocker 10, based on unused roll film storage request information sent from the unused roll film storage device 60. The outgoing rolled film specific information acquisition unit 31b acquires outgoing rolled film specific information, which is information that identifies the outgoing rolled film to be shipped from the rolled film stocker 10 (e.g., rolled film No.), from the information on the specific rolled film selected by the rolled film selection unit 31f (described later). The roll film management information update unit 31c updates the roll film management information, etc. in the roll film management information table 32a in the memory unit 32 using the incoming roll film management information acquired by the incoming roll film management information acquisition unit 31a and the outgoing roll film identification information acquired by the outgoing roll film identification information acquisition unit 31b. That is, the rolled film management information update unit 31c adds the incoming rolled film management information acquired by the incoming rolled film management information acquisition unit 31a to the rolled film management information table 32a in association with the stock table number on which the incoming rolled film is placed. Furthermore, the rolled film management information update unit 31c deletes the rolled film management information of the rolled film having the outgoing rolled film identification information acquired by the outgoing rolled film identification information acquisition unit 31b from the rolled film management information table 32a.

[0060] The roll film management information verification unit 31d includes a roll diameter verification unit 31d1, a film width verification unit 31d2, and a bar code information verification unit 31d3. The winding diameter verification unit 31d1 compares the winding diameter information sent from the winding film stocker control device 20 to the general computer 30 with the winding diameter stored in the winding film management information table 32a to verify whether the two winding diameters match. Specifically, first, when the rolled film is stored in the rolled film stocker 10 and placed on a stock table (one of the stock tables ST1 to ST10), the roll diameter calculation unit 21 calculates the roll diameter of the rolled film placed on that stock table based on the distance measured by the first distance sensor (one of the first distance sensors SA1 to SA1) installed on that stock table, and information on the calculated roll diameter is sent to the overall computer 30. Next, the winding diameter verification unit 31d1 verifies whether the winding diameter information received by the central computer 30 matches the winding diameter of the corresponding winding film stored in the winding film management information table 32a, and determines that the information is appropriate if the two winding diameters match or are within a certain tolerance range (for example, the difference between the two winding diameters is within 5% of the winding diameter received by the central computer 30), but determines that the information is inappropriate if the two winding diameters do not match and are not within the certain tolerance range. The film width verification unit 31d2 compares the film width information sent from the roll film stocker control device 20 to the general computer 30 with the film width stored in the roll film management information table 32a to verify whether the two film widths match. Specifically, first, when the rolled film is stored in the rolled film stocker 10 and placed on a stock table (one of the stock tables ST1 to ST10), the film width calculation unit 22 calculates the film width of the rolled film placed on that stock table based on the distance measured by the second distance sensor (one of the second distance sensors SB1 to SB1) installed on that stock table, and information on the calculated film width is sent to the overall computer 30. Next, the film width verification unit 31d2 verifies whether the film width information received by the central computer 30 matches the film width of the corresponding rolled film stored in the rolled film management information table 32a, and determines that the film width is appropriate if the two film widths match or are within a certain measurement error range, but determines that the film width is inappropriate if the two film widths do not match and are not within a certain measurement error range (for example, the difference between the two film widths is within 1% of the film width stored in the rolled film management information table 32a).

[0061] The barcode information verification unit 31d3 compares the product information in the barcode information sent from the roll film stocker control device 20 to the supervisory computer 30 with the product information stored in the roll film management information table 32a to verify whether the two pieces of information match. Specifically, first, when the rolled film is stored in the rolled film stocker 10 and placed on a stock table (one of stock tables ST1 to ST10), a barcode reader (one of barcode readers BR1 to BR10) installed on that stock table reads the barcode information of the rolled film placed on that stock table, and the read barcode information is sent to the general computer 30. Next, the barcode information verification unit 31d3 verifies whether the product information (product name) in the barcode information received by the central computer 30 matches the product information (product name) of the corresponding rolled film stored in the rolled film management information table 32a, and if the two pieces of information match, it determines that the information is appropriate, and if the two pieces of information do not match, it determines that the information is inappropriate. The verification results of winding diameter verification section 31d1, film width verification section 31d2, and barcode information verification section 31d3 are displayed on input display section 33 (details will be described later) and on each of display lamps Lp1 to Lp10. Specifically, if the verification results of the barcode information verification unit 31d3 are all correct, the winding diameter verification unit 31d1 and the film width verification unit 31d2 will light up the indicator lamp attached to the stock stand on which the rolled film is placed in green, and if any of the verification results of the barcode information verification unit 31d3 are incorrect, the winding diameter verification unit 31d1 and the film width verification unit 31d2 will light up the indicator lamp attached to the stock stand on which the rolled film is placed in red.

[0062] The packaging machine designation unit 31e designates a specific packaging machine (a packaging machine connected to the operation panel that sent the request information) from among the packaging machines 100 to 400 that needs to have the rolled film attached, based on the request information generated by each rolled film attachment request information generation unit of the operation panels 130 to 430 of the packaging machines 100 to 400 and transmitted from the operation panels 130 to 430, and sends information indicating the designated packaging machine to the unmanned transport robot control device 50. In addition, the packaging machine designation unit 31e designates a specific packaging machine (a packaging machine connected to the operation panel that sent the request information) from among the packaging machines 100 to 400 that needs to remove the remaining rolled film or paper tube, based on the request information generated by each rolled film removal request information generation unit or paper tube removal request information generation unit of the operation panels 130 to 430 of the packaging machines 100 to 400 and transmitted from the operation panels 130 to 430, and sends information indicating the designated packaging machine to the unmanned transport robot control device 50. The roll film selection unit 31f selects a specific roll film to be attached to the specific packaging machine from the roll films stored in the roll film stocker 10 based on the information stored in the roll film management information table 32a in the memory unit 32, and sends information identifying the stock table on which the selected specific roll film is placed (stock table number) to the unmanned transport robot control device 50. The stock table selection unit 31g selects an empty stock table on which the rolled film can be placed from among the stock tables installed in the rolled film stocker 10, based on the information stored in the rolled film management information table 32a in the memory unit 32, and sends information identifying the selected empty stock table to the unmanned transport robot control device 50.

[0063] Input display unit 33 has a touch panel display screen, and displays the verification results of roll film management information verification unit 31d (roll diameter verification unit 31d1, film width verification unit 31d2, bar code information verification unit 31d3). Specifically, the verified items (reel diameter, film width, product information) and the verification results (correct, incorrect) are displayed in association with the verified stock table number and verified reel film number. This allows the operator to know what is wrong with the rolled film placed on which stock table. The input display unit 33 also displays an operation screen for correcting the information in the roll film management information table 32a. This operation screen displays the items to be corrected (reel diameter, film width, product information) and the stock rack number and rolled film number to be corrected. When the worker selects the stock rack number to be corrected and the item to be corrected and enters the corrected value, the rolled film management information stored in the rolled film management information table 32a is corrected to the entered content. This allows the operator to match the information on the roll film stored in the roll film stocker 10 with the information stored in the roll film management information table 32a.

The shaft support portion 43 includes a holding shaft 43a, a pushing block 43b, and a lifting block 43c. One end of the holding shaft 43a is fixed to the front of the lifting block 43c, and holds the rolled film attached to the film supply section 111-411 of the packaging machine main body 110-410 of the packaging machine 100-400, or the remaining rolled film (including the paper tube) removed from the shaft 111b1-611b1 (111b2-611b2) of the film supply section 111-411, and also unused rolled film temporarily stored in the unused rolled film storage device 60. The push-out block 43b has a hole with an inner diameter slightly larger than the outer diameter of the holding shaft 43a, is connected to a push-out mechanism provided in the lift-up block 43c, and moves along the holding shaft 43a without coming into contact with the holding shaft 43a. The lifting block 43c is connected to a lifting mechanism provided in the box body 42, and moves up and down along the guide window 42m.

[0065] [Automated guided robot control device] As shown in FIG. 1, the unmanned transport robot control device 50 includes a travel control unit 51, a winding film pushing control unit 52, and a shaft lift control unit 53, and controls the operation of the unmanned transport robot 40. Based on information from the management control unit 31 of the overall management computer 30, the travel control unit 51 controls the travel operation of the travel base 41 so that the unmanned transport robot 40 travels to the roll film stocker 10, the unused roll film storage device 60, the roll film removal position of the packaging machines 100 to 400, or the roll film attachment position of the packaging machines 100 to 400, or even the roll film placement position of the roll film stocker 10. The winding film pushing control unit 52 controls the operation of the pushing mechanism provided in the lifting block 43c of the unmanned transport robot 40, and the shaft lifting control unit 43 controls the operation of the lifting mechanism provided in the box body . Then, under the control of the travel control unit 51 and the shaft lift control unit 53, the unmanned transport robot 40 travels from the standby position to the take-up film removal position of the take-up film stocker 10 to remove the specific take-up film selected by the take-up film selection unit 31f, and holds the take-up film on the holding shaft 43a. Furthermore, under the control of the travel control unit 51, the rolled film extrusion control unit 52, and the shaft lift control unit 53, the unmanned transport robot 40 holds the rolled film and travels from the rolled film removal position to the rolled film attachment position of a specific packaging machine (any of packaging machines 100 to 400) designated by the packaging machine designation unit 31e of the overall management computer 30, and the rolled film held by the shaft 43a is pushed out and supported by the support shaft of the specific film supply unit. In addition, under the control of travel control unit 51, rolled film push-out control unit 52, and shaft lift control unit 53, unmanned transport robot 40 holds the rolled film and travels from the rolled film removal position in unused rolled film storage device 60 to the rolled film placement position in rolled film stocker 10, and the unused rolled film held by shaft 43a is pushed out and placed on the stock table of rolled film stocker 10. Furthermore, under the control of the travel control unit 51, the winding film push-out control unit 52, and the shaft lifting control unit 53, the push-out block 43b and the lift-out block 43c return to their original positions, and the unmanned transport robot 40 travels from the winding film attachment position or the winding film placement position to the standby position.

[0066] [Packaging machine, roll film stocker, unused roll film storage device, and unmanned transport robot] FIG. 20 is a plan view showing the arrangement of packaging machines 100 to 400, roll film stocker 10, unused roll film storage device 60, and unmanned transport robot 40. As shown in FIG. In the figure, 210 is the packaging machine main body, 211 is the film supply section, 211a is the shaft support arm, 211b1 and 211b2 are support shafts, 212 is the tension adjustment section, 214a is the hopper, 219a is the belt conveyor, 410 is the packaging machine main body, 411 is the film supply section, 411a is the shaft support frame, 411b1 and 411b2 are support shafts, 412 is the packaging material feed section, 415 is the film pulling section, 416 is the center seal section, 417 is the weight setting section, 419 is the packaging body discharge section, MF2, MF4 are the rolled film, M212 and M213 are unused rolled film, and RE1, RE2, RE3, RE4, RE5, RE6, and RE7 are areas. The film supply section 211, shaft support arm 211a, support shafts 211b1 and 211b2, tension adjustment section 212, hopper 214a, and belt conveyor 219a in the packaging machine main body 210 of the packaging machine 200 are the same as the film supply section 111, shaft support arm 111a, support shafts 111b1 and 111b2, tension adjustment section 112, hopper 114a, and belt conveyor 119a in the packaging machine main body 110 of the packaging machine 100, respectively. In addition, the film supply section 411, shaft support frame 411a, support shafts 411b1, 411b2, packaging material feed section 412, film pulling section 415, center seal section 416, meshing section 417, and packaging body discharge section 419 in the packaging machine main body 410 of the packaging machine 400 are the same as the film supply section 311, shaft support frame 311a, support shafts 311b1, 311b2, packaging material feed section 312, film pulling section 315, center seal section 316, meshing section 317, and packaging body discharge section 319 in the packaging machine main body 310 of the packaging machine 300, respectively.

[0067] As shown in Figure 20, a packaging machine 100 is located in the farthest left area RE1, a packaging machine 200 is located in the farthest right area RE2, a packaging machine 300 is located in the second farthest left area RE3, a packaging machine 400 is located in the second farthest right area RE4, an unmanned transport robot 40 is located in the central area RE5, a rolled film stocker 10 is located in the second central area RE6 from the front, a rolled film loading device 60 is located in the farthest central area RE8, and unused rolled film storage device 60 temporarily stores unused rolled films M212 and M213. Then, the unmanned transport robot 40 travels from the section RER6 to the sections RE1 to RE4, and the rolled films M101 to M211 stored in the rolled film stocker 10 are loaded onto the packaging machines 100 to 400. Furthermore, the unmanned transport robot 40 travels between the areas RE1 to RE4 and the area RE6, removes the remaining rolled film from the packaging machines 100 to 400, and stores it in the rolled film stocker 10 for storage. Furthermore, the unmanned transport robot 40 travels between the area RE7 and the area RE6, and the unused rolled film that was temporarily stored in the unused rolled film storage device 60 is stored in the rolled film stocker 10.

[0068] [Operation of automatic winding film loading system 2] Regarding the operation of the roll film storage management system 1, the operation of the automatic roll film loading system 2, and the operation of the automatic roll film transport and storage system 3, the operation of the automatic roll film loading system 2 will be first described. FIG. 21 is a flowchart showing the operation of the automatic roll-up film loading system 2 when the unmanned transport robot 40 loads the roll-up film stored in the roll-up film stocker 10 onto the packaging machine 100. The operation of automatically loading the roll film into the packaging machine 100 will be described below with reference to the flowchart of FIG. First, on the operation panel 130 of the packaging machine 100, the roll-up film attachment request information generation unit 131b generates roll-up film attachment request information based on information requesting the attachment of roll-up film input from the input / display unit 134 and production information transmitted from the packaging machine control unit 120, and transmits the generated roll-up film attachment request information from the transmission / reception unit 133 to the overall management computer 30 (S1). In this case, the roll film mounting request information generated by the roll film mounting request information generating unit 131b includes information such as the product number and product name that identify the roll film to be mounted in the packaging machine 100.

[0069] Next, in the management control unit 31 of the overall management computer 30, based on the roll film loading request information transmitted from the operation panel 130, the packaging machine designation unit 31e designates the packaging machine 100 that requires the roll film to be loaded from among the packaging machines 100 to 400, and the roll film selection unit 31f selects a specific roll film to be loaded into the packaging machine 100 from among the roll films stored in the roll film stocker 10 based on the information stored in the roll film management information table 32a (S2). In this case, if the product number and product name included in the roll film loading request information from the operation panel 130 are "01" and "aaaa," the roll film selection unit 31f selects one of the roll film numbers "101" and "111" corresponding to the product number "01" and product name "aaaa," for example, the roll film with roll film number "101," as the specific roll film to be loaded into the packaging machine 100. Next, the overall management computer 30 issues a command to the unmanned transport robot control device 50 to load the rolled film (S3). This command to attach the roll film includes information about the packaging machine 100 designated by the packaging machine designation unit 31e and information about the stock table number "01" on which the roll film with roll film number "101" selected by the roll film selection unit 31f is stored. In response to a command from the overall management computer 30, the unmanned transport robot 40 travels from the waiting area RE5 to the take-up film removal position in area RE6 where the take-up film stocker 10 is located, and picks up the selected take-up film (take-up film M101 with take-up film number "101" stored on stock stand ST1 with stock stand number "01") (S4).

[0070] Figure 22 is an explanatory diagram illustrating the operation of the unmanned transport robot 40 raising the holding shaft 43a at the rolled film removal position in area RE6, Figure 22(a) is a plan view of the stock table ST1 of the rolled film stocker 10 (including the vicinity thereof, excluding sensor unit SU1) and the unmanned transport robot 40, and Figure 22(b) is a left side view of the stock table ST1 (including the vicinity thereof, excluding sensor unit SU1) and the unmanned transport robot 40, in which the dashed line SKH indicates the cardboard core hole of the rolled film M101, and in the figure, the holding shaft 43a and extrusion block 43b before being raised are represented by a two-dot chain line. In step S4, the unmanned transport robot 40 travels from area RE5 to area RE6 under the control of the travel control unit 51, and stops at a rolled film removal position, for example, on the front or back side of the stock table ST1 (the back side in Figure 22), as shown in Figure 22(a). In this case, the position for removing the rolled film is a position where the X-direction position of the center of the paper tube hole SKH of the rolled film M101 placed on the stock table ST1 coincides with the X-direction position of the holding shaft 43a of the unmanned transport robot 40, and the tip of the holding shaft 43a is close to the space formed by the front horizontal frames 12a, 13a and the adjacent front horizontal frame 13a. Then, in the unmanned transport robot 40, as shown in FIG. 22(b), the lifting block 43c is raised by the control of the shaft lifting control unit 53, and the holding shaft 43a is raised accordingly, as shown by the arrow AR1, until the height of the center of the holding shaft 43a from the floor surface FL matches the height of the center of the paper tube hole SKH. In this case, the height of the center of the cardboard tube hole SKH is determined by the winding diameter of the rolled film M101 placed on the stock table ST1, but the winding diameter of the rolled film M101 is the winding diameter calculated by the winding diameter calculation unit 21 based on the first distance information measured by the first distance sensor SA1, and is the actual winding diameter of the rolled film M101, so it is possible to easily and accurately match the height of the center of the holding shaft 43a from the floor surface FL with the height of the center of the cardboard tube hole SKH.

[0071] Figure 23 is an explanatory diagram illustrating the operation of the unmanned transport robot 40 to hold the rolled film on the holding shaft 43a at the rolled film removal position, Figure 23(a) is a plan view of the stock table ST1 (including the vicinity thereof, excluding the sensor unit SU1) of the rolled film stocker 10 and the unmanned transport robot 40, and Figure 23(b) is a left side view of the stock table ST1 (including the vicinity thereof, excluding the sensor unit SU1) and the unmanned transport robot 40, with the unmanned transport robot 40 before movement, and the holding shaft 43a, push-out block 43b, and rolled film M101 before lifting indicated by dashed double-dashed lines. After the unmanned transport robot 40 has raised the holding shaft 43a to the height of the paper tube hole SKH, under the control of the travel control unit 51, the unmanned transport robot 40 itself moves forward as shown by arrow AR2, and the front part of the traveling base 41 slips into the space between the underside of the base frame 11a of the rolled film stocker 10 and the floor surface FL, inserting the holding shaft 43a into the paper tube hole SKH until the tip of the holding shaft 43a protrudes slightly outside the rolled film M101 from the paper tube hole SKH. At this time, the outer diameter of the holding shaft 43a is slightly smaller than the inner diameter of the cardboard tube hole SKH, and the holding shaft 43a is inserted into the cardboard tube hole SKH without coming into contact with the inner surface of the cardboard tube hole SKH. In this state, the lifting block 43c rises under the control of the shaft lifting control unit 53, and as shown by the arrow AR3 in Figure 23(b), the holding shaft 43a rises and lifts the rolled film M101, so that the peripheral surface of the rolled film M101 is slightly separated from the loading rollers 16a1 and 16b1 of the stock table ST1.

[0072] In this way, in step S4, after the unmanned transport robot 40 holds the rolled film M101 on the holding shaft 43a, under the control of the travel control unit 51, the unmanned transport robot 40 moves backward while holding the rolled film M101, and after the rolled film M101 passes through the space formed by the front cross frames 12a, 13a and the adjacent front cross frame 13a, the unmanned transport robot 40 stops, and under the control of the shaft lifting control unit 53, the lifting block 43c descends to lower the holding shaft 43a holding the rolled film M101 to a predetermined height, and under the control of the travel control unit 51, the unmanned transport robot 40 runs to the rolled film attachment position of the packaging machine 100 while holding the rolled film M101, and attaches the rolled film M101 to the film supply unit 111 of the packaging machine 100 (S5). Figure 24 is an explanatory diagram illustrating the operation of the unmanned transport robot 40 at the take-up film attachment position of the packaging machine 100, where the take-up film M101 held by the holding shaft 43a is supported by the support shaft 111b2 of the film supply unit 111. Figure 24(a) is a plan view of the film supply unit 111 of the packaging machine 100 and the unmanned transport robot 40, and Figure 24(b) is a right and left side view of the film supply unit 111 of the packaging machine 100 and the unmanned transport robot 40. In the figure, 43d is a push-out rod, 111c is an arm support stand, and in the figure, the hold-out shaft 43a, push-out block 43b, and take-up film M101 before movement are represented by dashed double-dashed lines. In step S5, when the unmanned transport robot 40 reaches the take-up film mounting position of the packaging machine 100, a signal indicating that the unmanned transport robot 40 has reached the take-up film mounting position is sent from the unmanned transport robot control device 50 to the overall management computer 30 via communication line CL6, and the overall management computer 30 issues a command to the packaging machine control unit 120 via communication line CL1a to move the support shaft 111b2 of the shaft support arm 111a to the take-up film mounting position. In response to a command from this overall management computer 30, under the control of the support arm operation control unit 121a of the packaging machine control unit 120, the rotation shaft of the arm support stand 111c rotates, the shaft support arm 111a rotates, and the support shaft 111b2 moves to the take-up film attachment position. This take-up film attachment position is the position where the tilt angle of shaft support arm 111a is 0 (zero) and the arm is horizontal, and support shaft 111b2 is at the leftmost position. At this time, as shown in FIG. 24(a), the position of the center of the support shaft 111b2 in the X direction coincides with the position of the holding shaft 43a of the automatic guided robot 40 in the X direction. The operation of moving the support shaft 111b2 to the take-up film attachment position may be performed before the automatic guided robot 40 reaches the take-up film attachment position of the packaging machine 100.

[0073] Then, in the unmanned transport robot 40, as shown in Figure 24(b), the lifting block 43c rises under the control of the shaft lifting control unit 53, and as shown by arrow AR4, the holding shaft 43a rises accordingly, and the holding shaft 43a and the rolled film M101 rise until the height of the center of the holding shaft 43a from the floor surface FL matches the height of the center of the support shaft 111b2. After this, under the control of the winding film extrusion control unit 52, the extrusion rod 43d is extended rearward and the extrusion block 43b attached to its tip is moved rearward along the shaft 43a, so that the front side of the winding film M101 is pushed by the extrusion block 43b and moves rearward, and as shown by arrow AR5 in Figures 24(a) and (b), the extrusion block 43b and the winding film M101 move from above the holding shaft 43a onto the support shaft 111b2, and the winding film M101 is attached to the support shaft 111b2. Finally, under the control of the winding film extrusion control unit 53, the extrusion block 43b moves forward and returns to its original position, and under the control of the shaft lifting control unit 53, the lifting block 43c is lowered and the shaft 43a is lowered to its original position, and under the control of the traveling control unit 51, the unmanned transport robot 40 travels to area RE5 and returns to the standby position (S6), thereby completing the processing.

[0074] In addition, in the automatic roll film loading system 2, the operation when the unmanned transport robot 40 loads the roll film stored in the roll film stocker 10 onto packaging machines 200, 300, and 400 other than the packaging machine 100 is the same as the operation when loading the roll film onto the packaging machine 100. That is, when information requesting the loading of rolled film is sent to the overall management computer 30 from one of the operation panels 230, 330, 430 of the packaging machines 200, 300, 400 (for example, the operation panel 330 of the packaging machine 300), the packaging machine designation unit 31e designates the packaging machine (for example, the packaging machine 300) from among the packaging machines 100 to 400 that needs to have the rolled film loaded, and the rolled film selection unit 31f selects a specific rolled film to be loaded onto that packaging machine from the rolled films stored in the rolled film stocker 10 (for example, the rolled film with rolled film number "201" in the case of the packaging machine 300) based on the information stored in the rolled film management information table 32a.

[0075] Next, the overall management computer 30 issues a command to the unmanned transport robot control device 50 to load the rolled film, and the unmanned transport robot 40 travels from the waiting area RE5 to the rolled film removal position in area RE6 where the rolled film stocker 10 is located, and picks up the selected rolled film (for example, rolled film M201 with rolled film number "201" stored on stock stand ST6 with stock stand number "06"). In this case, the automatic guided robot 50 stops at a take-up film removal position on the front or rear side of the stock table (for example, stock table ST6). Then, the unmanned transport robot 50 takes out the rolled film (e.g., rolled film M201) from the front or back side of the stock table (e.g., stock table ST6), holds it on the holding shaft 53a, and travels to the packaging machine, and in the same operation as attaching the rolled film M101 to the packaging machine 100, attaches the rolled film (e.g., rolled film 201) to the support shaft of the rolled film supply unit of the packaging machine (e.g., support shaft 311b2 of the rolled film supply unit 311 of the packaging machine 300). In addition, in step S1, when request information for loading the rolled film is sent from the operation panel 330, 430 to the overall management computer 30, that is, when loading the rolled film into the packaging machine 300, 400, which is a horizontal pillow packaging machine, the shaft support frames 311a, 411a of the film supply unit 311, 411 are fixed and do not rotate, and the positions of the support shafts 311b2, 411b2 are fixed, so in step S6, no operation is performed to move the support shafts 311b2, 411b2 to the rolled film loading position, and the holding shaft 43a and the support shafts 311b2, 411b2 are aligned.

[0076] As described above, the automatic roll film loading system 2 includes the roll film stocker 10, the overall management computer 30, the unmanned transport robot 40, and the unmanned transport robot control device 50. The overall management computer 30 is connected to the packaging machine control units 120-420 of the packaging machines 100-400, the operation panels 130-430, the roll film stocker control device 20, and the unmanned transport robot control device 50 via communication lines. The overall management computer 30 includes a management control unit 31 and a memory unit 22. The management control unit 31 includes a packaging machine designation unit 31e and a roll film selection unit 31f. The memory unit 32 includes a roll film management information table 32a. The packaging machine designation unit 31e selects a roll film from the packaging machines 100-400 based on roll film loading request information transmitted from the operation panels 130-430 of the packaging machines 100-400. 00 to specify a specific packaging machine that requires the roll film to be installed, and roll film selection unit 31f selects a specific roll film to be installed in that specific packaging machine from the roll films stored in roll film stocker 10 based on the information stored in roll film management information table 32a, and based on this, unmanned transport robot 40 travels to the roll film removal position in roll film stocker 10, holds and transports the roll film selected by roll film selection unit 31f, and installs the transported roll film in the specific packaging machine.As a result, in packaging machines 100 to 400, the roll film stored in roll film stocker 10 is removed, automatically transported to each of packaging machines 100 to 400, and automatically installed in each of packaging machines 100 to 400.

[0077] [Operation of Automatic Roll Film Transport and Storage System 3, Part 1] Next, a first operation of the automatic roll film transport and storage system 3 (the operation of removing the remaining roll film from the packaging machine and storing it in the roll film stocker 10) will be described. Figure 25 is a flowchart showing the operations performed in the automatic roll film transport and storage system 3 when the roll film attached to the packaging machine 100 is removed and the unmanned transport robot 40 transports the removed roll film to the roll film stocker 10 for storage. The operation of automatically removing the roll film from the packaging machine 100 and storing it in the roll film stocker 10 will be described below with reference to the flowchart in FIG. First, on the operation panel 130 of the packaging machine 100, the roll film removal request information generation unit 131a generates roll film removal request information based on information requesting the removal of the roll film input from the input display unit 134 and production information transmitted from the packaging machine control unit 120, and transmits the generated roll film removal request information from the transmission / reception unit 133 to the overall management computer 30 (S11). In this case, the roll film removal request information generated by the roll film removal request information generating unit 131 a includes information such as the product number and product name that identify the roll film to be removed from the packaging machine 100 .

[0078] Next, in the management control unit 31 of the overall management computer 30, based on the roll film removal request information transmitted from the operation panel 130, the packaging machine designation unit 31e designates the packaging machine 100 from among the packaging machines 100 to 400 that needs to remove the roll film, and the stock table selection unit 31g selects an empty stock table from the stock tables of the roll film stocker 10 on which the roll film can be placed, based on the information stored in the roll film management information table 32a (S12). In this case, since the stock tables with stock table numbers "05" and "10" are empty in the rolled film management information table 32a, the stock table selection unit 32g selects one of the stock table numbers "05" and "10", for example, the stock table with stock table number "05", as the specific stock table on which the rolled film should be placed. Next, the overall management computer 30 issues a command to the unmanned transport robot control device 50 to remove the rolled film (S13). This command to remove the roll film includes information about the packaging machine 100 designated by the packaging machine designation unit 31e and information about the stock table No. "05" selected by the stock table selection unit 31g. In response to a command from this overall management computer 30, the unmanned transport robot 40 travels from the waiting area RE5 to the rolled film removal position of the packaging machine 100 and holds the rolled film that was attached to the film supply section 111 of the packaging machine 100 (S14).

[0079] Figure 26 is an explanatory diagram illustrating the operation of the unmanned transport robot 40 at the rolled film removal position of the packaging machine 100, where the unmanned transport robot 40 holds the rolled film attached to the support shaft 111b1 of the film supply unit 111 on the holding shaft 43a of the unmanned transport robot 40, Figure 26(a) is a plan view of the film supply unit 111 of the packaging machine 100 and the unmanned transport robot 40, and Figure 26(b) is a right side view of the film supply unit 111 of the packaging machine 100 and the unmanned transport robot 40, where MF1' is the remaining rolled film, and in the figure, the pusher 142 and the remaining rolled film MF1' before movement are represented by dashed double-dashed lines. In step S14, when the unmanned transport robot 40 reaches the take-up film removal position of the packaging machine 100, a signal indicating that the unmanned transport robot 40 has reached the take-up film removal position is sent from the unmanned transport robot control device 50 to the overall management computer 30 via communication line CL6, and the overall management computer 30 issues a command to the packaging machine control unit 120 via communication line CL1a to move the support shaft 111b1 on which the remaining take-up film MF1' to be removed is attached to the take-up film removal position. In the film supply section 111 of the packaging machine 100, the rolled film MF1, which was attached to one support shaft 111b1 and from which film was being unwound, has been consumed and the winding diameter has become smaller, and the unwinding of film has stopped, leaving it as remaining rolled film MF1', while the rolled film M101 is attached to the other support shaft 111b2, and film is being unwound from the rolled film M101 (see Figure 26(a)).

[0080] In response to the above command from the overall management computer 30, under the control of the support arm operation control unit 121a of the packaging machine control unit 120, the rotation shaft of the arm support stand 111c rotates, the shaft support arm 111a rotates, and the support shaft 111b1 moves to the take-up film removal position. This take-up film removal position is the position where the tilt angle of shaft support arm 111a is 0 (zero) and the support shaft 111b1 is in the horizontal position and at the leftmost position. At this time, as shown in Figure 26(a), the X-direction position of the center of the support shaft 111b1 and the X-direction position of the holding shaft 43a of the unmanned transport robot 40 coincide, and as shown in Figure 26(b), the height of the center of the support shaft 111b1 from the floor surface FL also coincides with the height of the holding shaft 43a of the unmanned transport robot 50 from the floor surface FL. The support shaft 111b1 may be moved to the take-up film removing position before the automatic guided robot 40 reaches the take-up film removing position of the packaging machine 100. Then, in the rolled film moving device 140, under the control of the pusher operation control unit 121b, the lifting mechanism of the stand 142a operates, and the lifting rod 142b rises so that the support shaft 111b1 is inside the notch 142k of the push plate 142d, as shown by arrow AR11.Then, the horizontal movement mechanism of the base table 141 operates, and the stand 142a moves in the Y direction (forward) along the top surface of the base table 141, as shown by arrow AR12, and the push plate 142d pushes the rear side of the remaining rolled film MF1', transferring the remaining rolled film MF1' from the support shaft 111b1 to the holding shaft 43a of the unmanned transport robot 40, and the unmanned transport robot 40 holds the remaining rolled film MF1'. After this, in the winding film moving device 140, under the control of the pusher operation control unit 121b, the lifting mechanism of the stand 142a operates, the lifting rod 142b descends, and the push plate 142d descends until the support shaft 111b1 is above the notch 142k, and the horizontal movement mechanism of the base stand 141 operates, causing the stand 142a to move in the Y direction (rearward) along the top surface of the base stand 141 and return to its original position. Furthermore, in automatic transport robot 40, shaft elevation control section 53 controls elevation block 43c to descend, and holding shaft 43a that holds remaining rolled film MF1' descends to a predetermined height.

[0081] Next, the unmanned transport robot 40, holding the remaining roll of film MF1', travels to the roll of film stocker 10 and places the remaining roll of film MF1' on the stock table ST5 from the front side (S15). Figure 27 is an explanatory diagram illustrating the operation of the unmanned transport robot 40 placing the remaining rolled film held by the holding shaft 43a at the rolled film insertion position onto the stock table of the rolled film stocker 10, where Figure 27(a) is a plan view of the stock table ST5 of the rolled film stocker 10 (including the surrounding area, excluding the sensor unit SU5) and the unmanned transport robot 40, and Figure 27(b) is a right side view of the stock table ST5 (including the surrounding area, excluding the sensor unit SU5) and the unmanned transport robot 40, and in the figure, the unmanned transport robot 40 before movement, the holding shaft 43a before lifting, the extrusion block 43b, and the remaining rolled film MF1' are represented by dashed double-dashed lines. In step S15, the stock rack selected by the overall management computer 30 is stock rack ST5 with stock rack number "05," so the unmanned transport robot 40 travels from area RE1 to area RE6 under the control of the travel control unit 51, and stops at the take-up film insertion position on the front or rear side of stock rack ST5 (the front side in FIG. 27) as shown in FIG. 27(a). In this case, the position for inserting the rolled film is such that the center position in the X direction of the holding shaft 43a of the unmanned transport robot 40 coincides with the middle position in the X direction of the adjacent front vertical frame 14a, and the tip of the holding shaft 43a is close to the space formed by the adjacent front vertical frame 14a and front horizontal frames 12a, 13a. Then, in the unmanned transport robot 40, as shown in Figure 27(b), the lifting block 43c rises under the control of the shaft lifting control unit 53, and as shown by arrow AR13, the remaining rolled film MF1' held by the holding shaft 43a rises accordingly, and the holding shaft 43a rises until its center in the Z direction is at the center position in the Z direction of the space formed by the adjacent front vertical frame 14a and front horizontal frames 12a, 13a.

[0082] After this, under the control of the travel control unit 51, the unmanned transport robot 40 itself moves forward, as shown by arrow AR14, and the front part of the travel base 41 slips into the space between the underside of the base frame 11a of the winding film stocker 10 and the floor surface FL, and the remaining winding film MF1' held by the holding shaft 43a is positioned above the loading rollers 16a5, 16b5 of the stock table ST5. In this state, the shaft lifting control unit 53 controls the lifting block 43c to lower, and as shown by arrow AR15 in Figure 27(b), the holding shaft 43a lowers and the remaining rolled film MF1' lowers, until the peripheral surface of the remaining rolled film MF1' abuts against the loading rollers 16a5, 16b5 of the stock table ST5.When the holding shaft 43a moves away from the paper tube hole SKH, the lowering of the holding shaft 43a stops, and under the control of the travel control unit 51, the unmanned transport robot 40 itself moves backward, and the unmanned transport robot 40 stops after the tip of the holding shaft 43a passes between the adjacent front vertical frames 14a. As a result, the remaining rolled film MF1' is placed on the stock table ST5 and stored in the rolled film stocker 10. Finally, in the unmanned transport robot 40, the shaft lifting control unit 53 controls the lifting block 43c to lower and the holding shaft 43a to a predetermined height, and then the travel control unit 51 controls the unmanned transport robot 40 to return to area RE5, which is its waiting position (S16), and the processing ends.

[0083] In addition, in the automatic roll film take-up, transporting, and storage system 3, when a roll film attached to a packaging machine other than the packaging machine 100 is removed and the unmanned transport robot 40 transports the removed remaining roll film to the roll film stocker 10 for storage, the operation is the same as that in the case of the packaging machine 100. That is, when request information for removing the rolled film is sent to the overall management computer 30 from one of the operation panels 230, 330, 430 of the packaging machines 200, 300, 400 (for example, the operation panel 330 of the packaging machine 300), the packaging machine designation unit 31e designates the packaging machine (for example, the packaging machine 300) from among the packaging machines 100 to 400 that needs to remove the rolled film, and the stock table selection unit 31g selects an empty stock table (for example, the stock table with stock table number "10") from the stock tables of the rolled film stocker 10 on which the rolled film can be placed, based on the information stored in the rolled film management information table 32a. Next, the overall management computer 30 issues a command to the unmanned transport robot control device 50 to remove the rolled film, and the unmanned transport robot 40 travels from the waiting area RE5 to the rolled film removal position of the designated packaging machine (e.g., packaging machine 300), and the rolled film moving device removes the remaining rolled film that was attached to the film supply section and has the unmanned transport robot 40 hold the removed remaining rolled film. Then, the unmanned transport robot 40, holding the rolled film, travels to the rolled film stocker 10 and places the remaining rolled film on a selected stock table (for example, stock table ST5 with stock table No. "05") from the front or back side. As a result, the remaining rolled film is automatically removed from the packaging machines 200, 300, and 400, transported to the rolled film stocker 10, and placed on a stock table for storage. In addition, in step S11, when information requesting the installation of the reel film is sent from the operation panel 330, 430 to the overall management computer 30, that is, when the reel film is to be removed from the packaging machine 300, 400, which is a horizontal pillow packaging machine, the shaft support frames 311a, 411a of the film supply unit 311, 411 are fixed and do not rotate, and the positions of the support shafts 311b2, 411b2 are fixed, so in step S14, the support shafts 311b2, 411b2 are not moved to the reel film removal position, and the holding shaft 43a and the support shafts 311b2, 411b2 are aligned.

[0084] [Operation of Automatic Roll Film Transport and Storage System 3, Part 2] Next, a second operation of the automatic rolled film transport and storage system 3 (the operation of removing unused rolled film from the unused rolled film storage device 60 and storing it in the rolled film stocker 10) will be described. Figure 28 is a flowchart showing the operations performed in the automatic rolled film transport and storage system 3 when unused rolled film stored in the unused rolled film storage device 60 is removed and the unmanned transport robot 40 transports the removed rolled film to the rolled film stocker 10 for storage. The operation of automatically removing unused rolled film from unused rolled film storage device 60 and storing it in rolled film stocker 10 will be described below with reference to the flowchart in FIG. First, in the computer of the unused rolled film storage device 60, the unused rolled film stocking request information generation unit generates unused rolled film stocking request information based on information requesting stocking in the rolled film stocker 10 input from the input / display unit, and transmits the generated unused rolled film stocking request information to the overall management computer 30 from the transmitter / receiver unit (S21). In this case, the unused roll film stock request information generated by the unused roll film stock request information generation unit includes roll film management information (product number, product name, etc.) that identifies the unused roll film that is requested to be stocked. Now, let us assume that the unused rolled film storage device 60 stores an unused rolled film M212 with rolled film number "212" and an unused rolled film M213 with rolled film number "213" (see Figure 20), and the unused rolled film stocking request information includes rolled film management information for the unused rolled film M212.

[0085] Next, in the management control unit 31 of the overall management computer 30, based on the used roll film storage request information sent from the unused roll film storage device 60, the stock table selection unit 31g selects an empty stock table from the stock tables of the roll film stocker 10 on which the roll film can be placed, based on the information stored in the roll film management information table 32a (S22). In this case, since the stock tables with stock table numbers "05" and "10" are empty in the rolled film management information table 32a, the stock table selection unit 32g selects one of the stock table numbers "05" and "10", for example, stock table 10 with stock table number "10", as the specific stock table on which the rolled film should be placed. Next, the overall management computer 30 issues a command to the unmanned transport robot control device 50 to store the unused rolled film (S23). This storage command for the unused roll of film includes information on the stock rack No. "10" selected by the stock rack selection unit 31g. In response to a command from the overall management computer 30, the unmanned transport robot 40 travels from the waiting area RE5 to the unused rolled film removal position in the unused rolled film storage device 60, and picks up the unused rolled film M212 that has been stored in the unused rolled film storage device 60 (S24). In this case, the unused rolled film M212 is stored with its peripheral surface placed on the unused rolled film placing table, just like the rolled film placed on the stock table of the rolled film stocker 10, and the unmanned transport robot 40 holds the unused rolled film M212 on the holding shaft 43a in the same manner as when removing the rolled film from the rolled film stocker 10 (see step S4 in Figure 21, Figures 22 and 23).

[0086] Next, the unmanned transport robot 40, holding the unused rolled film M212, travels to the rolled film stocker 10 and places the unused rolled film M301 on the stock table ST10 from the front side (S25). In step S25, the stock stand selected by the overall management computer 30 is stock stand ST10 with stock stand number "10," so the unmanned transport robot 40 travels from area RE7 to area RE6 under the control of the travel control unit 51 and stops at the rolled film insertion position on the front or back side of the stock stand ST10. Then, in the same manner as the remaining rolled film MF1' removed from the packaging machine 100 is placed on the stock table ST5, the unused rolled film M212 held on the holding shaft 43a is placed on the stock table ST10 (see FIG. 27). As a result, the unused rolled film M212 is placed on the stock stand ST10 and stored in the rolled film stocker 10. Finally, in the unmanned transport robot 40, the shaft lifting control unit 53 controls the lifting block 43c to lower and the holding shaft 43a to a predetermined height, and then the travel control unit 51 controls the unmanned transport robot 40 to return to area RE5, which is its waiting position (S26), and the processing ends.

[0087] As described above, the roll film automatic transport and storage system 3 includes the roll film stocker 10, the overall management computer 30, the unmanned transport robot 40, and the unmanned transport robot control device 50, as well as the roll film moving device or unused roll film storage device 60 for each of the packaging machines 100 to 400. The overall management computer 30 controls the packaging machine control units 120 to 420, the operation panels 130 to 430, the roll film stocker control device 20, the unmanned transport robot control device 50, and the unused roll film storage device 60 for each of the packaging machines 100 to 400. The management computer 30 is connected to the film storage device 60 via a communication line, and includes a management control unit 31 and a memory unit 32. The management control unit 31 includes a packaging machine designation unit 31e and a stock table selection unit 31g. The memory unit 32 includes a roll film management information table 32a. The packaging machine designation unit 31e designates a specific packaging machine from among the packaging machines 100 to 400 that needs to remove the roll film based on roll film removal request information transmitted from the operation panels 130 to 430 of the packaging machines 100 to 400. The stock table selection unit 31g selects a roll film management information table 32a. Based on the information stored in the film management information table 32a, an empty stock table on which a roll of film can be placed is selected from the stock tables installed in the roll of film stocker 10, and based on this, the unmanned transport robot 40 travels to the roll of film removal position of a specific packaging machine, and the roll of film moving device causes the unmanned transport robot 40 to hold the remaining roll of film attached to the specific packaging machine, or the unmanned transport robot 40 travels to the unused roll of film storage device 60 and holds the unused roll of film that has been temporarily stored in the unused roll of film storage device 60, and the remaining roll of film or unused roll of film held by the unmanned transport robot 40 is transported to the roll of film stocker 10 and placed on the stock table.As a result, the remaining roll of film attached to the packaging machines 100 to 400 or the unused roll of film that has been temporarily stored in the used roll of film storage device 60 can be automatically transported to the roll of film stocker 30, and the transported roll of film can be automatically stored in the roll of film stocker 30.

[0088] [Operation of Roll Film Storage Management System 1] Finally, the operation of the roll film storage management system 1 will be described. Figure 29 is a flowchart showing the operation of the roll film storage management system 1 when an incoming roll film (remaining roll film or unused roll film) is stored in the roll film stocker 10 and the roll film management information is verified. The operation when the rolled film management information of the stored rolled film is verified will be described below based on the flowchart of FIG. First, the incoming roll film management information acquisition unit 31a acquires incoming roll film management information based on roll film removal request information transmitted from the operation panels 130-430 of the packaging machines 100-400 to the overall management computer 30, or unused roll film receiving request information transmitted from the unused roll film storage device 60 to the overall management computer 30 (S31). For example, if a request for removal of a roll of film is sent from the operation panel 130 of the packaging machine 100 to the overall management computer 30, and the request for removal of a roll of film includes the roll of film management information of roll of film No. "112", product No. "02", product name "bbbb", roll of diameter "250", and film width "700", the incoming roll of film management information acquisition unit 31a acquires the roll of film No. "112", product No. "02", product name "bbbb", roll of diameter "250", and film width "700" as the incoming roll of film management information. Furthermore, when unused rolled film storage device 60 transmits unused rolled film inventory request information to central management computer 30 and the unused rolled film inventory request information includes rolled film No. "212," product No. "12," product name "eeee," roll diameter "300," and film width "850" as rolled film management information, incoming rolled film management information acquisition unit 31a acquires the rolled film No. "212," product name "eeee," roll diameter "500," and film width "850" as the incoming rolled film management information.

[0089] Next, the remaining rolled film corresponding to the rolled film removal request information sent to the overall management computer 30 (for example, the remaining rolled film MF1' with rolled film No. "112") is removed from the packaging machine by the unmanned transport robot 40 and transported to the rolled film stocker 10, where it is placed on the stock stand selected by the stock stand selection unit 31g (for example, stock stand ST5 with stock stand No. "05"), and the detection sensor detects that the remaining rolled film has been placed on the stock stand. In addition, the unused rolled film corresponding to the unused rolled film storage request information sent to the overall management computer 30 (unused rolled film M212 with rolled film number "212") is taken out of the unused rolled film storage device 60 by the unmanned transport robot 40 and transported to the rolled film stocker 10, where it is placed on the stock stand selected by the stock stand selection unit 31g (for example, stock stand ST10 with stock stand number "10"), and the detection sensor detects that the unused rolled film has been placed on the stock stand. This completes the storage process for the incoming roll film, and the roll film stocker control device 20 transmits information indicating the completion of the storage process to the overall management computer 30 (S32). Furthermore, when the storage process for the incoming rolled film is completed, the indicator lamp on the stock stand on which the incoming rolled film is placed (for example, indicator lamp Lp5 on stock stand ST5 or indicator lamp Lp10 on stock stand ST10) lights up blue, notifying the worker that the storage process for the incoming rolled film has been completed.

[0090] In the overall management computer 30, when information indicating the completion of the inventory process is received from the reel film stocker control device 20, the reel film management information update unit 31c updates the reel film management information in the reel film management information table 32a in the memory unit 32 with the inventory reel film management information acquired by the inventory reel film management information acquisition unit 31a (S33). For example, if the incoming rolled film management information acquisition unit 31a acquires the following information as incoming rolled film management information from the rolled film removal request information sent from the operation panel 130 of the packaging machine 100: rolled film No. "112", product No. "02", product name "bbbb", roll diameter "250", and film width "700", and the remaining rolled film MF1' with rolled film No. "112" is placed on stock stand ST5 with stock stand No. "05", the rolled film management information update unit 31c adds and registers (stores) the information of rolled film No. "112", product No. "02", product name "bbbb", roll diameter "250", and film width "700" in the column for stock stand No. "05" in the rolled film management information table 32a. Furthermore, when the incoming rolled film management information acquisition unit 31a acquires the following information as incoming rolled film management information from the unused rolled film receiving request information sent from the unused rolled film storage device 60: rolled film No. "212", product No. "12", product name "eeee", roll diameter "500", and film width "850", and the unused rolled film M212 with rolled film No. "212" is placed on stock stand No. "10" of stock stand ST10, the rolled film management information update unit 31c adds and registers (stores) the information of rolled film No. "212", product No. "12", product name "eeee", roll diameter "500", and film width "850" in the column for stock stand No. "10" of the rolled film management information table 32a. FIG. 30 is an explanatory diagram illustrating the structure of the rolled film management information table 32a updated by the stocked rolled film management information acquisition unit 31a. As shown in FIG. 30, the roll film number, product number, product name, roll diameter, and film width information are additionally registered in the stock rack number "05" and "10" columns of roll film management information table 32a.

[0091] Furthermore, when the storage procedure in step S32 is completed, in the reel film stocker control device 20, for the stored reel film stored in the reel film stocker 10, the reel diameter calculation unit 21 calculates the reel diameter, the film width calculation unit 22 calculates the film width, the barcode reader control unit 23 controls the reading operation of the barcode reader to read the barcode information, and the calculated reel diameter and film width information and the read barcode information are sent to the overall management computer 30 (S34). For example, when the remaining rolled film MF1' is placed on the stock table ST5 of the rolled film stocker 10 and the storage process is completed, the first distance sensor SA5 of the sensor unit SU1 measures the distance to the top of the circumferential surface of the remaining rolled film MF1', and based on this, the rolled diameter calculation unit 21 calculates the rolled diameter of the remaining rolled film MF1' (e.g., 235 mm). Second distance sensor SB5 measures the distance to the side surface on the front side of remaining rolled film MF1', and film width calculation unit 22 calculates the film width (for example, 705 mm) of rolled film MF1' based on this. Furthermore, the motor operation command control unit 24 rotates the loading table motor of the stock table ST5 to rotate the loading rollers 16a5, 16b5 and rotate the remaining rolled film MF1' at a low speed, and the barcode reader control unit 23 issues a reading command to the barcode reader BR5 of the sensor unit SU5, and the barcode reader BR5 reads the barcode information (for example, product name "bbbb") printed on the remaining rolled film MF1'. Then, information on the winding diameter of the remaining wound film MF1' calculated by the winding diameter calculation unit 21, information on the film width of the wound film MF1' calculated by the film width calculation unit 22, and barcode information of the wound film MF1' read by the barcode reader BR5 are transmitted to the overall management computer 30.

[0092] In the overall management computer 30, to which the winding diameter, film width, and barcode information has been sent from the winding film stocker control device 20, the winding film management information verification unit 31d compares and verifies the sent winding diameter, film width, and barcode information with the winding film management information stored in the winding film management information table 32a updated by the winding film management information update unit 31c (S35). Specifically, the winding diameter verification unit 31d1 verifies whether the winding diameter information received by the central computer 30 matches the winding diameter of the corresponding winding film stored in the winding film management information table 32a updated by the winding film management information update unit 31c, and determines that the information is appropriate if the two winding diameters match or are within a certain tolerance range, and determines that the information is inappropriate if the two winding diameters do not match and are not within the certain tolerance range. For example, if the information on the winding diameter of the remaining rolled film MF1' received by the central computer 30 is 235 mm and the winding diameter of the remaining rolled film MF1' (rolled film No. "112") stored in the updated rolled film management information table 32a is 250 mm, the difference between the two winding diameters exceeds the allowable range of 5%, and the winding diameter verification unit 31d1 determines that it is inappropriate. Furthermore, the film width verification unit 31d2 verifies whether the film width information received by the central computer 30 matches the film width of the corresponding rolled film stored in the rolled film management information table 32a updated by the rolled film management information update unit 31c, and determines that the film width is appropriate if the two film widths match or are within a certain measurement error range, and determines that the film width is inappropriate if the two film widths do not match and are not within the certain measurement error range. For example, if the film width information of the remaining rolled film MF1' received by the central computer 30 is 705 mm and the film width of the remaining rolled film MF1' (rolled film No. "112") stored in the updated rolled film management information table 32a is 700 mm, the difference between the two film widths does not exceed 1%, which is within the measurement error range, and the film width verification unit 31d2 determines that the difference is appropriate. Furthermore, the barcode information verification unit 31d3 verifies whether the product information (product name) in the barcode information received by the central computer 30 matches the product information (product name) of the corresponding rolled film stored in the rolled film management information table 32a updated by the rolled film management information update unit 31c, and determines that the information is appropriate if it matches, and determines that the information is inappropriate if it does not match. For example, if the product information (product name) in the barcode information of the remaining rolled film MF1' received by the central computer 30 is "bbbb," and the product name of the remaining rolled film MF1' (rolled film No. "112") stored in the updated rolled film management information table 32a is "bbbb," the two pieces of information match, and the barcode information verification unit 31d3 determines that the information is appropriate.

[0093] Then, input display unit 33 displays the verification results of roll film management information verification unit 31d (roll diameter verification unit 31d1, film width verification unit 31d2, barcode information verification unit 31d3) on the display screen (S36). FIG. 31 is a diagram showing the screen layout of a screen that displays the verification results of the roll film management information verification unit 31d, in which 33a is a display screen, and 33b1 and 33b2 are operation buttons. Figure 31 shows a state in which a remaining roll of film MF1' with roll number "112" and an unused roll of film M212 with roll number "212" are stored in the roll of film stocker 10, the remaining roll of film MF1' is placed on stock stand ST5, and the unused roll of film M212 is placed on stock stand ST10, and the roll of film management information verification unit 31d performs verification in step S35, with the verification results displayed on the display screen 33a. As shown in Figure 31, the display screen 33a displays the item names "Stock Table No.", "Rolled Film No.", "Product No.", "Product Name", "Rolling Diameter", and "Film Width" along with their corresponding numerical values ​​or letters in the form of a list, with the columns for unverified stock table Nos. 01 to 04 and 06 to 09 displayed in a darkened state (displayed in gray in Figure 32), and verified stock table No. 05 (containing remaining rolled film MF1') and stock table No. 10 (containing unused rolled film M212) displayed in a brightened state. In the columns for stock tables No. 05 and 10, the verified product name, winding diameter, and film width are displayed as verification results, with a "◯" if they are correct, and an "X" if they are incorrect. In this case, the rolled film management information verification unit 31d verified the remaining rolled film MF1' and the unused rolled film M212, and found that only the roll diameter of the remaining rolled film MF1' was incorrect, while the others were correct.Therefore, as shown in Figure 31, among the product name, roll diameter, and film width columns for stock racks No. 05 and 10, an ``X'' is displayed in the roll diameter column for stock rack No. 05, and ``O'' is displayed in the other columns.

[0094] In this case, in response to the verification result of the roll film management information verification unit 31d in step S35, the lamp display control unit of the roll film stocker control device 20 lights up the display lamp installed on the stock table on which the remaining roll film or unused roll film that was the subject of verification is placed in a color corresponding to the verification result. As described above, when the remaining rolled film MF1' is placed on the stock stand ST5, and the rolled film management information verification unit 31d finds that only the roll diameter of the remaining rolled film MF1' is incorrect, the lamp display control unit controls the display lamp Lp5 of the stock stand ST5 to light up red, indicating that either the roll diameter, film width, or product information (product name) is incorrect. Furthermore, when an unused rolled film M212 is placed on the stock stand ST10, and the rolled film management information verification unit 31d finds that the roll diameter, film width, and product information of the unused rolled film M212 are all correct, if only the roll diameter of the remaining rolled film MF1' is incorrect, the lamp display control unit controls the indicator lamp Lp10 of the stock stand ST10 to light up green. In this way, the verification results of the film management information verification unit 31d are displayed on the display screen 33a of the input display unit 33, and the indicator lamp of the roll film stocker 10 lights up in a color corresponding to the verification result, allowing the worker to easily know which information is incorrect for which roll film placed on which stock table.

[0095] With respect to the display of such verification results, it is determined whether or not the verification results should be corrected (S37). On the display screen 33a, below the list, there are displayed an operation button 33b1 with the words "Modify verification results" and an operation button 33b2 with the words "Do not modify verification results." When the worker touches the operation button 33b1, it is determined in step S37 that the verification results will be modified, and when the worker touches the operation button 33b2, it is determined in step S37 that the verification results will not be modified. Then, if it is determined in step S37 that the verification result should be corrected, that is, if the worker touches the operation button 33b1, an operation screen (not shown) for correcting the information in the rolled film management information table 32a is displayed on the input display unit 33. This operation screen displays the items to be corrected (reel diameter, film width, product information), the stock rack number to be corrected, the rolled film number, etc., and when the worker selects the stock rack number to be corrected (for example, "05"), selects the item to be corrected (for example, "reel diameter"), and enters the numerical value to be corrected (for example, "235"), the rolled film management information stored in rolled film management information table 32a is corrected to the entered content (for example, the rolled diameter of stock rack No. 05 is 235 mm) (S38), and the process ends. Also, if it is determined in step S37 that the verification result is not to be corrected, that is, if the worker touches the operation button 33b2, the process ends. This allows the operator to easily match the information on the roll film stored in the roll film stocker 10 with the information stored in the roll film management information table 32a.

[0096] FIG. 32 is a flowchart showing the operation of the roll film storage management system 1 when the roll film is delivered from the roll film stocker 10 and the roll film management information in the roll film management information table 32a is updated. Hereinafter, the operation when the rolled film management information in the rolled film management information table 32a is updated due to the delivery of the outgoing rolled film will be described with reference to the flowchart of FIG. First, on the operation panel 130 of the packaging machine 100, the roll-up film attachment request information generation unit 131b generates roll-up film attachment request information based on information requesting the attachment of roll-up film input from the input / display unit 134 and production information transmitted from the packaging machine control unit 120, and transmits the generated roll-up film attachment request information from the transmission / reception unit 133 to the overall management computer 30 (S41). In this case, the roll film mounting request information generated by the roll film mounting request information generating unit 131b includes information such as the product number and product name that identify the roll film to be mounted in the packaging machine 100. Next, in the management control unit 31 of the overall management computer 30, based on the roll film loading request information transmitted from the operation panel 130, the packaging machine designation unit 31e designates the packaging machine 100 that needs to have the roll film loaded from among the packaging machines 100 to 400, and the roll film selection unit 31f selects, based on the information stored in the roll film management information table 32a, from the roll films stored in the roll film stocker 10, a specific roll film to be loaded into the packaging machine 100 designated by the packaging machine designation unit 31e (S42). For example, if the product number and product name included in the roll film loading request information from the operation panel 130 are "01" and "aaaa," the roll film selection unit 31f selects one of the roll film numbers "101" and "111" corresponding to the product number "01" and product name "aaaa," for example, the roll film with roll film number "101," as the specific roll film to be loaded into the packaging machine 100. Next, the outgoing rolled film specific information acquisition unit 31b acquires outgoing rolled film specific information, which is information that identifies the outgoing rolled film to be shipped from the rolled film stocker 10 (e.g., rolled film No.), from the information on the specific rolled film selected by the rolled film selection unit 31f (S43). If the specific rolled film selected by the rolled film selection unit 31f in step S42 is the rolled film with rolled film number "101", the outgoing rolled film identification information acquisition unit 31b acquires rolled film number "101" as the outgoing rolled film identification information.

[0097] After this, when the roll film corresponding to the roll film loading request information sent to the overall management computer 30 (for example, roll film M101 with roll film number "101") is removed from the roll film stocker 10 by the unmanned transport robot 40, the detection sensor of the stock table on which the removed roll film was placed (for example, stock table ST1 with stock table number "01") detects that the roll film is no longer placed on the stock table. This completes the shipping process for the outgoing rolled film, and the rolled film stocker control device 20 transmits information indicating the completion of the shipping process to the overall management computer 30 (S44). In addition, when the outgoing roll film shipping process is completed, the indicator lamp on the stock stand on which the outgoing roll film is placed (for example, indicator lamp Lp1 on stock stand ST1) will go out from its blue lit state, notifying the worker that the outgoing roll film shipping process is complete. Finally, when the overall management computer 30 receives information indicating the completion of the shipping process from the roll film stocker control device 20, the roll film management information update unit 31c updates the roll film management information, etc. in the roll film management information table 32a in the memory unit 32 based on the shipping roll film specific information acquired by the shipping roll film specific information acquisition unit 31b (S45), and the processing is terminated. For example, if the outgoing rolled film identification information acquired by the outgoing rolled film identification information acquisition unit 31b is rolled film No. "101," the rolled film management information update unit 31c deletes the rolled film management information corresponding to stock table No. "01" in which rolled film No. "101" is stored in the rolled film management information table 32a.

[0098] As described above, the roll film storage management system 1 includes the roll film stocker 10 and the overall management computer 30. The roll film stocker 10 includes the first distance sensors SA1 to SA10 and roll diameter calculation unit 21 that measure the roll diameter of the roll film placed on the stock tables ST1 to ST10, the second distance sensors SB1 to SB10 and film width calculation unit 22 that measure the film width, the bar code readers BR1 to BR10 that read bar code information, and the bar code reader control unit 23. The overall management computer 30 is configured to control the roll film storage management system 100 to 400. The packaging machine control units 120 to 420, the operation panels 130 to 430, the roll film stocker control unit 20, and the unmanned transport robot control unit 50 are connected by communication lines. The overall management computer 30 includes a management control unit 31 and a memory unit 22. The management control unit 31 includes an incoming roll film management information acquisition unit 31a, an outgoing roll film specific information acquisition unit 31b, a roll film management information update unit 31c, and a roll film management information verification unit 31d. The memory unit 32 includes a roll film management information table 32a. The incoming roll film management information acquisition unit 31a is connected to the operation panel 130. Based on the roll film removal request information or unused roll film storage request information transmitted from the packaging machines 100-400 or unused roll film storage device 60, the unit 31b acquires incoming roll film management information, which is roll film management information related to the incoming roll film (remaining roll film or unused roll film) that is removed from the packaging machines 100-400 or taken out from the unused roll film storage device 60 and stored in the roll film stocker 10, and the unit 31b acquires the outgoing roll film specific information related to the incoming roll film that is removed from the packaging machines 100-400 or taken out from the unused roll film storage device 60 and stored in the roll film stocker 10. The roll film management information update unit 31c updates the roll film management information in the roll film management information table 32a in the storage unit 32 based on the incoming roll film management information acquired by the incoming roll film management information acquisition unit 31a and the outgoing roll film identification information acquired by the outgoing roll film identification information acquisition unit 31b. The roll film management information verification unit 31d updates the roll film management information in the roll film management information table 32a in the storage unit 32 based on the incoming roll film management information acquired by the incoming roll film management information acquisition unit 31a and the outgoing roll film identification information acquired by the outgoing roll film identification information acquisition unit 31b.The barcode information verification unit 31d3 is provided, and the winding diameter verification unit 31d1 verifies whether the winding diameter information transmitted from the winding film stocker control device 20 to the central computer 30 matches the winding diameter stored in the winding film management information table 32a, and verifies whether the two winding diameters match. The film width verification unit 31d2 verifies whether the film width information transmitted from the winding film stocker control device 20 to the central computer 30 matches the film width stored in the winding film management information table 32a, and verifies whether the two film widths match. The unit 31d3 verifies whether the product information in the barcode information sent from the roll film stocker control device 20 to the central computer 30 matches the product information stored in the roll film management information table 32a, and the verification results of the roll film management information verification unit 31d are displayed on the input / display unit 33 of the central management computer 30, so that the consistency between the information on the roll film stored in the roll film stocker 10 and the information stored in the roll film management information table 32a can be easily verified by simple means.
