Description

[Technical field]

[0001] The present invention relates to a conveyor device used in a weight checker or the like, and a sorting device equipped with the conveyor device. [Background technology]

[0002] For example, agricultural and marine products and other items are sorted into ranks according to their weight, and items of the same rank are packed into boxes or bags. In this way, weight sorters are used to sort items into ranks according to their weight.

[0003] A conventional weight sorter includes, for example, a weighing conveyor that weighs the articles while transporting the articles in one direction, and a sorting device that sorts the articles according to the weights of the articles weighed by the weighing conveyor downstream of the weighing conveyor. The sorting device includes, for example, a conveyor that transports the articles in one direction, and a sorting means such as a sorting arm.

[0004] Furthermore, there is also a conventional multi-row weight checker having multiple rows of weighing conveyors and sorting devices (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2007-316029 A Summary of the Invention [Problem to be solved by the invention]

[0006] Conventionally, in a multiple-row weight sorter that handles articles such as fish, for example, when the size of the articles is changed due to a change in the type of article such as fish, the interval between the multiple rows of weighing conveyors may be changed according to the size of the articles such as fish so that the articles in adjacent rows do not come into contact with each other during transportation. The interval between the multiple rows of weighing conveyors may also be changed due to a change in the surrounding work space, etc. In this way, when the interval between the multiple rows of weighing conveyors is changed, the interval between the multiple conveyors of the sorting device must also be changed according to the interval.

[0007] In a device equipped with multiple conveyors arranged side by side in the width direction, such as this sorting device, conventionally, for example, multiple conveyors are arranged side by side on one large stand, but when changing the interval between the conveyors, the conveyors and their drive motors, etc. must be removed from the stand and changed, which is a cumbersome task and takes a long time to complete. There is a demand for an easy task of changing the interval between multiple rows of conveyors.

[0008] The present invention has been made to solve the above-mentioned problems, and aims to provide a conveyor device and a sorting device equipped with the same that can easily change the spacing between conveyors that are arranged side by side in the width direction. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, a conveyor device according to one embodiment of the present invention comprises a plurality of conveyors arranged in a horizontal direction perpendicular to the direction of transport of articles, a plurality of stands corresponding to each of the conveyors and supporting the conveyors from below, and a base portion on which the plurality of stands are placed and fixed, the base portion being configured to allow the position of the stands in the arrangement direction of the conveyors to be variably fixed.

[0010] According to this configuration, the base portion is configured so that the position of the stand in the direction in which the conveyors are arranged can be changed, making it easy to change the spacing between conveyors arranged side by side in the width direction (the horizontal direction perpendicular to the direction in which the articles are transported).

[0011] Further, the base portion has a plurality of mounting tables that extend in the alignment direction of the conveyor and on which the plurality of racks are placed, the mounting tables having a receiving portion at a lower end portion thereof that extends in the conveying direction and is placed on the plurality of mounting tables, the receiving portion of the mounting table and a predetermined mounting portion of the mounting table to which the receiving portion is attached are fastened using a bolt, and the mounting portion of the mounting table may be provided with a long hole through which the bolt can be inserted and through which the bolt can be moved in the alignment direction of the conveyor.

[0012] In addition, a sorting device according to one embodiment of the present invention comprises the above-mentioned conveyor device and a plurality of sorting means provided corresponding to each conveyor of the conveyor device and configured to remove articles transported by the conveyor from the conveyor, each of the sorting means being attached to a stand supporting the corresponding conveyor.

[0013] According to this configuration, when changing the interval between the conveyors, if the interval between the stands is changed, the sorting means also moves together with the stands, so there is no need to change the mounting position of the sorting means.

[0014] The conveyor device may further include a first and a second conveyor as the plurality of conveyors, and the plurality of sorting means may include a first sorting means for removing articles transported by the first conveyor from the first conveyor to the opposite side to the second conveyor, and a second sorting means for removing articles transported by the second conveyor from the second conveyor to the opposite side to the second conveyor.

[0015] With this configuration, the distance between the first and second conveyors can be narrowed, and the distance between the stands supporting the first and second conveyors can be narrowed, allowing the base portion on which these stands are placed to be miniaturized. Effect of the Invention

[0016] The present invention has the above-described configuration and has the effect of providing a conveyor device and a sorting device equipped with the same, which can easily perform the task of changing the spacing between conveyors arranged side by side in the width direction.

[0018] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following, the same or corresponding elements are denoted by the same reference numerals throughout the drawings, and duplicated descriptions thereof may be omitted. In addition, the drawings are schematic illustrations of the respective components for ease of understanding, and shapes, dimensional ratios, and the like may not be accurately depicted. In addition, the present invention is not limited to the following embodiments.

[0019] (Present embodiment) FIG. 1(A) is a schematic diagram showing the general configuration of a weight sorter equipped with a sorting device of one example of this embodiment, viewed from above, and FIG. 1(B) is a schematic diagram showing the general configuration of the same weight sorter, viewed from the side.

[0020] First, an outline of a weight sorter equipped with a sorting device 100 according to an example of this embodiment will be described. This weight sorter sorts items such as agricultural and marine products, such as fruits and seafood, into a predetermined number of weight ranks, and includes two feed conveyors 1, two weighing conveyors 2 each supported by a weight sensor 2a such as a load cell, a sorting device 100 equipped with two sorting conveyors 3 and sorting arms 8, 9, an electrical equipment storage box 5, an operation display 6, and a control device 7. Around each sorting conveyor 3, for example, containers (containers) B1 to B4 for storing items are arranged.

[0021] An operation display unit 6 is fitted into the upper front part of the electrical equipment storage box 5, and a control device 7 is housed inside. The operation display unit 6 is configured using, for example, a touch panel display, and is equipped with an input means for operating the weight sorter and setting its operating conditions, and a display means for displaying the weight value of the articles, etc. on a display screen. The control device 7 inputs signals from the operation display unit 6 and outputs signals such as data to be displayed on the operation display unit 6.

[0022] The control device 7 is configured with, for example, a microcomputer, and controls the operation of the entire weight checker. Thus, the control device 7 controls the operations of the two feed conveyors 1, the two weighing conveyors 2, the two sorting conveyors 3, and the sorting arms 8 and 9. The control device 7 may be configured with a single control device that performs centralized control, or may be configured with multiple control devices that cooperate with each other to perform distributed control.

[0023] This weight checker is a multiple-type weight checker having multiple (here, two) conveying lines CL1 and CL2, each of which is made up of an infeed conveyor 1, a weighing conveyor 2, and a sorting conveyor 3. The infeed conveyor 1, the weighing conveyor 2, and the sorting conveyor 3 of the two conveying lines CL1 and CL2 are arranged parallel to each other in a horizontal direction (the width direction of the conveyor) perpendicular to the article conveying direction (the direction of the arrow a).

[0024] In each of the conveying lines CL1, CL2, for example, a supply conveyor (not shown) is provided in front of the infeed conveyor 1. Articles are supplied to this supply conveyor from an operator or a front-stage device (not shown), and the articles are transported to the infeed conveyor 1. The infeed conveyor 1 receives the articles transported sequentially by the supply conveyor, and transfers them to the weighing conveyor 2. The weighing conveyor 2 receives the articles transported by the infeed conveyor 1, and transfers them to the sorting conveyor 3.

[0025] The control device 7 inputs a weighing signal from the weight sensor 2a attached to the weighing conveyor 2 for each of the transport lines CL1 and CL2, and acquires the weight of the article on the weighing conveyor 2 weighed by the weight sensor 2a at a predetermined timing based on a detection signal from an article detection sensor (not shown) provided between the feed conveyor 1 and the weighing conveyor 2, for example, and determines which of a plurality of preset weight ranks the weight of the article belongs to. Then, based on the determination result, the control device 7 controls the operation of the sorting arms 8 and 9 by controlling an arm driving device 12 (see FIG. 2, etc.) described later.

[0026] Here, for each of the transport lines CL1 and CL2, four weight ranks are set, for example, consisting of three weight ranks for standard products, numbered 1 to 3, and a weight rank for non-standard products. These weight ranks can be set by the user by operating the operation display device 6.

[0027] For example, the weight range for standard products can be set to be equal to or greater than the lower limit weight value WL and equal to or less than the upper limit weight value WU, and the range below the lower limit weight value WL and the range above the upper limit weight value WU can be set to weight ranks for non-standard products.The weight range for standard products can then be divided into three and first, second and third weight ranks can be set.

[0028] For example, by operating the sorting arms 8 and 9 at positions corresponding to each of the storage boxes B1 to B3, items of the first weight rank are stored in storage box B1, items of the second weight rank are stored in storage box B2, and items of the third weight rank are stored in storage box B3, and so on, items of the first to third weight ranks are stored in storage boxes B1 to B3.

[0029] For example, in the first conveying line CL1, in the case of an article of a first weight rank, the sorting arm 8 corresponding to the storage box B1 rotates around the rotating shaft 10 as shown by the two-dot chain line and advances onto the sorting conveyor 3 of the first conveying line CL1, so that the article conveyed on the sorting conveyor 3 in the direction of the arrow a is stored in the storage box B1. In addition, in the second conveying line CL2, in the case of an article of a second weight rank, the sorting arm 9 corresponding to the storage box B2 rotates around the rotating shaft 10 as shown by the two-dot chain line and advances onto the sorting conveyor 3 of the second conveying line CL2, so that the article conveyed on the sorting conveyor 3 in the direction of the arrow a is stored in the storage box B2. For an article belonging to the weight rank of nonstandard items, the sorting arms 8 and 9 are not operated in either conveying line CL1 or CL2, so that the article is stored in the nonstandard item storage box B4.

[0030] As described above, in this example, the sorting arm 8 provided corresponding to the sorting conveyor 3 of the first conveyor line CL1 is configured to remove articles transported by the sorting conveyor 3 to the opposite side of the sorting conveyor 3 of the second conveyor line CL2. Also, the sorting arm 9 provided corresponding to the sorting conveyor 3 of the second conveyor line CL2 is configured to remove articles transported by the sorting conveyor 3 to the opposite side of the sorting conveyor 3 of the first conveyor line CL1.

[0031] In order for the control device 7 to accurately control the timing at which each sorting arm 8, 9 operates, an item detection sensor can be provided at the discharge end of the weighing conveyor 2 or halfway through the sorting conveyor 3 on each conveying line CL1, CL2, and the detection signal can be input to the control device 7.

[0032] Next, a specific example of the sorting device 100 will be described in detail. Fig. 2 is a plan view of the sorting device 100 as viewed from above. Fig. 3(A) is a side view of the sorting device 100, Fig. 3(B) is a schematic diagram showing the framework and base part 90 of the two racks 50 of the sorting device 100, and Fig. 3(C) is a schematic diagram showing the framework of one rack 50. Fig. 4 is an enlarged view of the sorting device 100 as viewed from the downstream side in the conveying direction of the sorting conveyor 3.

[0033] The sorting device 100 includes the sorting conveyors 3 of the transport lines CL1 and CL2, a drive unit (motor 3M and drive transmission unit 3S) for operating the sorting conveyors 3, a plurality of sorting arms 8 and 9, arm drive units 12 (12A, 12B: see FIG. 4) for operating the sorting arms 8 and 9, discharge chutes 40 provided corresponding to the sorting arms 8 and 9, two racks 50 (50a, 50b) for supporting the sorting conveyors 3 of the transport lines CL1 and CL2, and a base unit 90 for supporting the two racks 50. The discharge chute 40 is provided with a jump prevention plate 40a (FIGS. 3(A) and 4) for preventing articles from jumping out of the sorting conveyors 3. In addition, a jump prevention plate 41 (FIG. 4) is attached to the side frames 34 and 35 on the adjacent sides of the two sorting conveyors 3 over substantially the entire length of the sorting conveyors 3. These anti-jut-out plates 40a and 41 are not shown in FIG.

[0034] The sorting conveyor 3 is a belt conveyor that conveys articles in a predetermined horizontal direction (arrow a direction), and includes a driving pulley 31 on the upstream side in the conveying direction (arrow a direction), a driven pulley 32 on the downstream side, an endless belt 33 made of a flat belt, a pair of side frames 34, 35 (FIG. 4) that extend in the conveying direction and are arranged opposite each other, and a plurality of rod-shaped connecting parts 36 (FIG. 4) that connect the side frames 34, 35. As shown in FIG. 4, each side frame 34, 35 is formed, for example, of an L-shaped angle with an L-shaped cross section, and has vertical parts 34a, 35a and horizontal parts 34b, 35b.

[0035] The driving pulley 31 and the driven pulley 32 are rotatably attached to both ends of the side frames 34, 35 in the conveying direction, and a conveying belt 33 is wound around the pulleys 31, 32. That is, the endless conveying belt 33 is wound around the driving pulley 31 and the driven pulley 32. The driving pulley 31 is rotated by a motor (driving motor) 3M via a drive transmission unit 3S. Although the cover member of the drive transmission unit 3S is shown and its interior is not shown, it can have a well-known configuration, for example, it is configured by winding a timing belt between a pulley to which the rotation of the motor 3M is transmitted and a pulley provided at one end of the driving pulley 31. The motor 3M is fixed to the frame 50 at the upstream end side in the conveying direction of the sorting conveyor 3.

[0036] As shown in Figure 2, the sorting arms 8 are arranged in a row in the conveying direction at a predetermined interval on one side of the width direction of the sorting conveyor 3 of one conveying line CL1, and the sorting arms 9 are arranged in a row in the conveying direction at a predetermined interval on the other side of the width direction of the sorting conveyor 3 of the other conveying line CL2.

[0037] As shown in Fig. 4, each of the sorting arms 8, 9 has a rotating shaft 10 extending in the vertical direction, and an arm portion 11 that is fixed to the upper end of the rotating shaft 10 and removes articles from the sorting conveyor 3 as the rotating shaft 10 is rotated. The arm portion 11 is, for example, the portion illustrated as the sorting arms 8, 9 in Fig. 2. Each of the sorting arms 8, 9 is provided with an arm driving device 12 (12A, 12B) disposed below the sorting conveyor 3.

[0038] The arm driving device 12 has a housing 13 having a substantially rectangular parallelepiped shape with a top panel 13a through which the rotating shaft 10 passes, and a driving unit that rotates the rotating shaft 10 of the distribution arms 8, 9 is housed inside this housing 13. This driving unit can be of a known configuration that rotates the rotating shaft 10 forward and backward using, for example, an air cylinder or a motor.

[0039] The arm drive device 12A of the sorting arm 8 and the arm drive device 12B of the sorting arm 9 are configured to rotate the pivot shaft 10 of the sorting arm 8 and the pivot shaft 10 of the sorting arm 9 in opposite directions during the operation of the sorting arms 8, 9 to remove articles from each sorting conveyor 3 (for example, the operation shown by the dotted line in Figure 1 (A)).

[0040] In this example, the arm drive device 12A of each sorting arm 8 has a bottom plate 13b of its housing 13 fixed to a support frame 51 of the stand 50a with bolts or the like (not shown), and a horizontal portion 34b of one side frame 34 of the sorting conveyor 3 of the transfer line CL1 is fixed to the top plate 13a with bolts or the like (not shown). The horizontal portion 35b of the other side frame 35 of the sorting conveyor 3 is supported by a plurality of pillars 38 arranged side by side in the transfer direction on the support frame 52 of the stand 50a.

[0041] Similarly, the arm drive device 12B of each sorting arm 9 has a bottom plate 13b of its housing 13 fixed to the support frame 52 of the stand 50b with bolts or the like (not shown), and a horizontal portion 35b of one side frame 35 of the sorting conveyor 3 of the transfer line CL2 is fixed to the top plate 13a with bolts or the like (not shown). The horizontal portion 34b of the other side frame 34 of the sorting conveyor 3 is supported by a plurality of pillars 38 arranged side by side in the transfer direction on the support frame 51 of the stand 50b.

[0042] In this manner, each sorting conveyor 3 is supported by the housings 13 of the arm driving devices 12A, 12B and the plurality of pillars 38 on each frame 50. In other words, each sorting conveyor 3 is supported by each frame 50 from below.

[0043] Further, a discharge chute 40 is provided for each of the sorting arms 8, 9. The discharge chute 40 has an inclined surface that allows articles removed from the sorting conveyor 3 by the sorting arms 8, 9 to slide downward to avoid the arm driving devices 12A, 12B. Therefore, by allowing the articles removed from the sorting conveyor 3 by the sorting arms 8, 9 to slide down the discharge chute 40, they can be stored, for example, in storage boxes B1 to B3 without colliding with the arm driving devices 12A, 12B arranged extending to the side of the sorting conveyor 3.

[0044] In this embodiment, as shown in FIG. 3, two platforms 50 (50a, 50b) that support each sorting conveyor 3 of the conveying lines CL1, CL2 from below are attached on a base part 90. As shown in FIG. 3(C), each platform 50 includes support frames 51, 52 that extend in parallel to the conveying direction (arrow a direction) of the sorting conveyor 3, connecting frames 53, 54 that connect both ends of the two support frames 51, 52, four support frames 55-58 that support both ends of the two support frames 51, 52, and lower frames 59-62 that connect the lower ends of the support frames 55-58. Each frame 51-62 can be formed of, for example, an equilateral angle, and is connected by welding or the like. Each platform 50 (50a, 50b) has frames 51-62 that form the sides of a rectangular parallelepiped, and may be provided with a member such as a frame for reinforcement, if necessary.

[0045] The base portion 90 is composed of a plurality of (two in this example) placement tables 90a, 90b arranged apart from each other in the conveying direction of the sorting conveyor 3 (the direction of the arrow a).

[0046] FIG. 5 is a perspective view of the two racks 50 (50a, 50b) and the base portion 90 as viewed obliquely from below.

[0047] Each of the placement tables 90a, 90b constituting the base 90 includes a placement body 91 that is installed extending in the arrangement direction (arrow b direction) of the multiple sorting conveyors 3, and two legs 92 consisting of height adjustment adjusters attached to the lower part of the placement body 91. The placement body 91 also includes an upper frame 91a, a lower frame 91b, and vertical frames 91c to 91f that connect the upper frame 91a and the lower frame 91b. The upper frame 91a, the lower frame 91b, and the vertical frames 91c to 91f are connected at their respective connection points by welding or the like. The upper frame 91a is a mounting part on which the multiple racks 50a, 50b are placed and attached. The two legs 92 are attached to the lower frame 91b so that the height can be adjusted.

[0048] The upper frame 91a of each of the mounting tables 90a, 90b is provided with two long slots 93, 94 in the arrangement direction (arrow b direction) of the two sorting conveyors 3 in order to mount the two stands 50a, 50b. These slots 93, 94 are formed to be large enough that the shaft portion of the bolt BT passed through the slot can move in the longitudinal direction of the slot (the arrangement direction of the sorting conveyors 3).

[0049] The base 50a is fixed on the bases 90a and 90b by fastening the lower frame (receiving portion) 59, 60 of the base 50a to the upper frame (mounting portion) 91a of each of the bases 90a and 90b with the bolts BT through the two long holes 93 of each of the bases 90a and 90b. For example, each of the lower frames 59, 60 of the base 50a is provided with screw holes (not shown) that screw into the bolts BT at two predetermined positions spaced apart in the longitudinal direction. The position of the base 50a in the arrangement direction (arrow b direction) of the multiple sorting conveyors 3 can be changed by loosening the bolts BT and shifting the base 50a in the direction of the arrow b and re-tightening the bolts BT.

[0050] Similarly, the base 50b is fixed on the bases 90a and 90b by passing bolts BT through the two long holes 94 of each of the bases 90a and 90b and fixing the lower frames 59 and 60 of the base 50b to the upper frames 91a of each of the bases 90a and 90b with bolts BT. For example, each of the lower frames 59 and 60 of the base 50b is provided with screw holes (not shown) that screw into the bolts BT at two predetermined positions spaced apart in the longitudinal direction. The position of the base 50b in the arrangement direction (arrow b direction) of the multiple sorting conveyors 3 can be changed by loosening the bolts BT, shifting the base 50b in the direction of the arrow b, and then retightening the bolts BT.

[0051] In this example, a screw hole (not shown) into which the bolt BT screws is provided in the lower frame 59, 60 of each of the mounting bases 50a, 50b. Alternatively, a through hole into which the shaft of the bolt BT is inserted may be provided in the lower frame 59, 60, and the lower frame 59, 60 of the mounting bases 50a, 50b and the upper frame 91a of each of the mounting bases 90a, 90b may be fixed using the bolt BT and a nut.

[0052] In this embodiment, the mounting parts (lower frames 59, 60) of the stands 50a, 50b and the predetermined mounting parts (upper frames 91a) of the mounting tables 90a, 90b to which the mounting parts are attached are fastened using bolts BT, and the mounting parts (upper frames 91a) of the stands 90a, 90b are provided with long holes 93, 94 into which the bolts BT are inserted and through which the bolts BT can move in the arrangement direction (arrow b direction) of the sorting conveyor 3. In this way, the base part 90 is configured to be able to changeably fix the positions of the stands 50a, 50b in the arrangement direction (arrow b direction) of the sorting conveyor 3, so that by changing the positions of the stands 50a, 50b on the base part 90, it is possible to easily change the interval between the sorting conveyors 3, 3 arranged side by side in the width direction (arrow b direction) of the sorting conveyor 3. Therefore, it is easy to change the interval between the sorting conveyors 3, 3 in response to changes in the size of the articles to be transported, etc. For example, when the transported goods are fish and the type of fish is changed from a small one to a large one, it is easy to widen the gap between the platforms 50a, 50b to widen the gap between the sorting conveyors 3, 3 so that the fish on the adjacent sorting conveyors 3, 3 do not come into contact with each other. Also, in order to increase the working space around the sorting device 100, it is easy to narrow the gap between the platforms 50a, 50b on which the sorting conveyors 3 are placed.

[0053] Furthermore, in the sorting device 100, the sorting means (sorting arm 8 and arm driving device 12A) corresponding to the sorting conveyor 3 of the conveying line CL1 is attached to the frame 50a, and the sorting means (sorting arm 9 and arm driving device 12B) corresponding to the sorting conveyor 3 of the conveying line CL2 is attached to the frame 50b. Therefore, when changing the spacing between the sorting conveyors 3, 3, if the spacing between the frames 50a, 50b is changed, the sorting means also moves together with the frames 50a, 50b, so there is no need to change the mounting position of the sorting means.

[0054] In addition, in this embodiment, the sorting arm 8 corresponding to the sorting conveyor 3 of the conveying line CL1 is configured to remove items on the sorting conveyor 3 to the opposite side to the sorting conveyor 3 of the conveying line CL2, and the sorting arm 9 corresponding to the sorting conveyor 3 of the conveying line CL2 is configured to remove items on the sorting conveyor 3 to the opposite side to the sorting conveyor 3 of the conveying line CL1.Therefore, the distance between the two sorting conveyors 3,3 can be narrowed, the distance between the stands 50a, 50b supporting each of the two sorting conveyors 3,3 can be narrowed, the length of the mounting stands 90a, 90b on which these stands 50a, 50b are placed can be shortened, and the base portion 90 can be made smaller.

[0055] In this embodiment, the sorting arms (8, 9) are arranged side by side in the conveying direction of the sorting conveyor 3 on the side of the sorting conveyor 3, but a configuration in which only one sorting arm is arranged on each sorting conveyor 3 is also possible. The length of the sorting conveyor 3 (length in the conveying direction) may be appropriately changed depending on the number of sorting arms, etc. Furthermore, when the length of the sorting conveyor 3 is longer, three or more mounting tables constituting the base portion 90 may be provided.

[0056] Furthermore, the configuration of the base part consisting of multiple stands and multiple mounting tables in this embodiment can be applied not only to multiple conveyors (sorting conveyor 3) used in the sorting device, but also to multiple other conveyors arranged in parallel.

[0057] In this embodiment, belt conveyors are used for the feed conveyor 1, the weighing conveyor 2, and the sorting conveyor 3, but roller conveyors or the like may be used depending on the type of article to be conveyed.

[0058] From the above description, many improvements and other embodiments of the present invention will be apparent to those skilled in the art. Therefore, the above description should be construed as merely illustrative and is provided for the purpose of teaching those skilled in the art the best mode for carrying out the present invention. Details of the structure and / or function thereof may be substantially changed without departing from the spirit of the present invention. [Industrial Applicability]

[0059] INDUSTRIAL APPLICABILITY The present invention is useful as a conveyor device that can easily perform the operation of changing the interval between conveyors that are arranged side by side in the width direction, and as a sorting device including the same. [Explanation of symbols]
