Description

[Technical field]

[0001] The present invention relates to an oblate supplying device for supplying oblates. [Background technology]

[0002] Conventionally, sticky items such as gummies are placed in a tray and pillow-packaged with the tray top covered with an oblate to prevent the items from drying out. A device for pulling out and supplying a film from an original roll has been proposed in which a circular turret is provided with suction holes, and the turret with the film sucked to its outer periphery is rotated to pull out and cut a predetermined length of the film from the original roll, and the cut film is supplied to a supply position (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 63-272617 Summary of the Invention [Problem to be solved by the invention]

[0004] In the device disclosed in Patent Document 1, the film is drawn by adsorption to the outer peripheral surface of a circular turret, so that the film takes on an arc shape while being drawn to the supply position. That is, when an oblate is used as the film, the oblate that is drawn to the supply position and cut takes on an arc shape, so in a configuration in which the oblate is dropped onto the upper surface of the tray, a part of the falling oblate (the top of the arc shape) reaches the upper surface of the tray first. Since oblate is highly hygroscopic, when a part of the oblate that reaches the upper surface of the tray first comes into contact with a sticky object, the contact part absorbs moisture, and at the same time, the surrounding area releases the absorbed moisture and dries, causing the oblate to curl. In this case, the oblate does not cover the tray in a flat state, and a part of the object in the tray is transferred to the next process while being exposed, which causes problems such as the object drying out, or the curled part of the oblate getting caught in various devices during processing in the next process.

[0005] An object of the present invention is to provide an oblate supplying device that can supply cut oblates to a tray without causing the cut oblates to curl when supplied to the tray. [Means for solving the problem]

[0006] The oblate supplying device of the invention according to claim 1 of the present application is: An oblate supplying device that supplies cut oblates (15a) cut from a strip of oblate (15) to an article storage section (12a) of a tray (11) transported by a transport conveyor (10), a rotary supply body (18) that is rotatably supported above the transport conveyor (10), has a plurality of flatly formed holding portions (20) that are spaced apart in the circumferential direction and are capable of adsorbing the strip-shaped oblate (15), and draws out the strip-shaped oblate (15) from a supply source (16, 17) by rotating; a cutting means (19) for cutting the strip-shaped oblate (15) held by the circumferentially adjacent holding portions (20, 20) of the rotary supply body (18) between the adjacent holding portions (20, 20); a lifting means (21) for lifting the tray (11) conveyed by the conveyor (10) to below the rotary feed body (18) so as to approach the holding portion (20) at a feed position (S) facing downward on the rotary feed body (18); The holding portion (20) which adsorbs the cut oblate (15a) cut off from the strip-shaped oblate (15) is positioned at the supply position (S) by the rotation of the rotary supply body (18), and in a state in which the tray (11) is lifted by the lifting means (21), the adsorption of the holding portion (20) at the supply position (S) is released, so that the cut oblate (15a) is supplied to the article storage portion (12a) of the tray (11). In the invention according to claim 1, the strip-shaped oblate is sucked onto the flatly formed holding portion of the rotary supply body and drawn out, and the cut oblate separated from the strip-shaped oblate is sucked flat onto the holding portion and positioned at the supply position, so that the cut oblate can be supplied in a flat state to the article storage portion of the tray. In other words, it is possible to prevent only a part of the cut oblate from first coming into contact with the article stored in the tray, and it is possible to prevent the cut oblate from curling. In addition, because the cut oblate is supplied to the tray that is lifted by the lifting means and approaches the holding portion, the cut oblate that has left the holding portion by releasing the suction can be supplied to an appropriate position with respect to the article storage portion of the tray.

[0007] In the invention according to claim 2, the transport conveyor (10) is configured to transport the trays (11) in a plurality of rows in the direction of the rotation axis of the rotary supply body (18), The supply sources (16, 17), rotary supplies (18), cutting means (19) and lifting means (21) are provided in the same number as the number of rows of trays (11) transported by the transport conveyor (10), and are provided in correspondence with each row of trays (11). According to the invention of claim 2, a plurality of cut wafers can be supplied to a plurality of trays at once, thereby improving the processing capacity.

[0008] The invention according to claim 3 is characterized in that it includes a pressing means (36) for pressing the cut oblate (15a) supplied to the tray (11) against the article (14) stored in the article storage section (12a). According to the invention of claim 3, the articles contained in the tray and the cutting oblate can be brought into close contact with each other, and drying of the articles can be suppressed.

[0009] The invention according to claim 4 is characterized in that an auxiliary conveyor (24) for suction-transporting the strip-shaped oblate (15) with a suction belt (24a) is provided in the transport path of the strip-shaped oblate (15) between the supply source (16, 17) and the rotary supply body (18). According to the invention of claim 4, the tensile force applied to the band-shaped oblate when it is pulled out from the supply source is dispersed, and the band-shaped oblate can be prevented from breaking.

[0010] In the invention of claim 5, the cutting means (19) is provided with a knife (30) which moves back and forth relative to the rotating supply body (18), and the knife (30) is inserted into a groove (18a) provided in the rotating supply body (18) to cut the strip-shaped oblate (15). According to the invention of claim 5, the soft band-shaped oblate can be cut well. Effect of the Invention

[0011] According to the present invention, cut wafers can be supplied to a tray in a flat state, which prevents the cut wafers from curling, prevents the items stored in the tray from drying out, and prevents problems from occurring in subsequent processes. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Next, a preferred embodiment of an oblate supplying device according to the present invention will be described below with reference to the accompanying drawings. EXAMPLES

[0014] The wafer supplying device of the embodiment shown in Fig. 1 is a device that supplies cut wafers 15a of a size corresponding to the size of an article storage section 12a to an article storage section 12a of a tray 11 that has been transported by a transport conveyor 10 from a previous process such as a manufacturing machine. As shown in Figs. 2 and 4, the tray 11 is a container having a main body 12 in which a rectangular article storage section 12a is defined, and a flange 13 extending outward from the outer periphery of the main body 12, and a plurality of sticky articles 14 such as gummies are stored in the article storage section (six in the embodiment). The wafer supplying device includes a roll support section 17 that rotatably supports an original roll 16 on which strip-shaped wafer 15 having a width corresponding to the width dimension of the article storage section 12a in the tray 11 is wound with a predetermined diameter; a rotating supplying body 18 that adsorbs the strip-shaped wafer 15 from the original roll 16 supported by the roll support section 17 to its outer surface and rotates to pull out the strip-shaped wafer 15 from the original roll 16; cutting means 19 that cuts the strip-shaped wafer 15 adsorbed to the outer surface of the rotating supplying body 18 to a length corresponding to the length of the article storage section 12a in the tray 11; a plurality of flat-formed holding sections 20 that are provided on the outer surface of the rotating supplying body 18 and can adsorb the strip-shaped wafer 15 or cut wafers 15a cut from the strip-shaped wafer 15 by the cutting means 19; and a lifting means 21 that lifts the tray 11, which has been transported to below the rotating supplying body 18 by the transport conveyor 10, to a receiving position M approaching the rotating supplying body 18. The roll support section 17 and the original roll 16 supported by the roll support section 17 constitute a supply source of the strip-shaped oblate 15 .

[0015] As shown in Fig. 1 and Fig. 2, the transport conveyor 10 arranged below the rotary feeder 18 is a conveyor in which a plurality of support stays 23 are installed in parallel, spaced apart in the tray transport direction, between a pair of endless chains 22, 22 spaced apart in the width direction intersecting the tray transport direction, and is configured to support and transport a plurality of (in the embodiment, nine) trays 11 in the width direction between the support stays 23, 23 adjacent to each other in the tray transport direction. Each support stay 23 is provided with nine receiving parts 23a in the width direction, and the receiving parts 23a, 23a facing each other in the tray transport direction support from below the flanges 13 extending from the main body 12 of the tray 11 to the front and rear in the tray transport direction. The transport conveyor 10 is configured to intermittently transport the trays 11 supplied between the support stays 23, 23 by a robot or the like in a plurality of rows (nine rows), and to intermittently stop each row of trays 11 at a lifting position N facing below the rotary feeder 18.

[0016] As shown in FIG. 1, the roll support parts 17 for rotatably supporting the original roll 16 are arranged above the transport conveyor 10 in the same number as the number of rows of the trays 11 transported by the transport conveyor 10. The original roll 16 in the embodiment is a roll of a bobbin-shaped winding body 16a having a pair of flanges formed at both axial ends of the body, on which a strip-shaped oblate 15 is wound, and the ends protruding outward from each flange are rotatably supported by bearing parts provided on the roll support parts 17. As shown in FIG. 3, the nine roll support parts 17 are arranged in a distributed manner at intervals in the tray transport direction. In the embodiment, one roll support part 17 is arranged at the center position in the width direction, and four roll support parts 17 are arranged at a distance downstream of the roll support part 17 in the width direction, and four roll support parts 17 are arranged downstream of the roll support parts 17 in the width direction, and each of these nine roll support parts 17 is arranged corresponding to each row of the trays 11 transported by the transport conveyor 10. An auxiliary conveyor 24 consisting of an adsorption conveyor having a running adsorption belt 24a capable of adsorbing the underside of the strip-shaped oblate 15 is disposed downstream of each roll support section 17 (the transport path of the strip-shaped oblate 15 up to the rotary supply body 18), and is configured so that the auxiliary conveyor 24 pulls out the strip-shaped oblate 15 from the original roll 16 supported by the roll support section 17. The auxiliary conveyor 24 runs the adsorption belt 24a intermittently in synchronization with the intermittent rotation of the rotary supply body 18.

[0017] 1, roll support parts 17 for supporting spare original rolls 16 are disposed corresponding to the roll support parts 17, and a splicer 25 for splicing the leading end of a new strip oblate 15 of an original roll 16 supported by the spare roll support parts 17 to an old strip oblate 15 in use supported by the roll support parts 17 is disposed above the auxiliary conveyor 24. The splicer 25 includes an adsorption member 26 that adsorbs the upper surface of the leading end of the new strip oblate 15 and is movable up and down. The splicer 25 adsorbs the leading end of the new strip oblate 15 to the adsorption member 26 located at a standby position spaced above the auxiliary conveyor 24, and waits with double-sided tape affixed to the underside of the leading end. The adsorption member 26 is lowered to press the double-sided tape affixed to the new strip oblate 15 against the upper rear end surface of the old strip oblate 15, thereby joining the old and new strip oblates 15, 15. The joint between the old and new strip-shaped oblates 15, 15 is tracked by the path length of the strip-shaped oblate 15 from the joint position by the splicer 25 to the rotary supply body 18 and by a rotation detector such as an encoder provided in the rotation system of the rotary supply body 18, and the time when the holding part S, which has adsorbed the cut oblate 15a including the joint, reaches the supply position S can be obtained. The tray 11 on which the cut oblate 15a including the joint is supplied and disposed on the transport conveyor 10 is determined to be a defective product and is discharged out of the system downstream of a pressing means 36 described later.

[0018] As shown in Figs. 1 and 5, the rotary supply 18 is rotatably supported above the transport conveyor 10 on the downstream side of the most downstream roll support unit 17. In the embodiment, a hollow rotary shaft 28 is rotatably supported between machine frames 27, 27 spaced apart in the width direction, and the rotary supply 18, the number of which is the same as the number of rows of trays 11 transported in multiple rows by the transport conveyor 10, is arranged on the rotary shaft 28 so as to be aligned in the axial direction and rotate integrally. As shown in Fig. 4, the rotary supply 18 has a polygonal cross section perpendicular to the axial direction of the rotary shaft 28. In the embodiment, the rotary supply 18 is formed into a substantially hexagonal shape in which six flat holding portions 20 capable of supporting substantially the entire cut oblate 15a cut from the strip oblate 15 are formed at equal intervals in the circumferential direction. The holding portions 20 are set to have an outer dimension that is substantially the same as the opening dimension of the article storage portion 12a in the tray 11. Furthermore, a plurality of suction holes 20a are formed in each holding part 20, and a negative pressure source is connected to the rotating shaft 28, so that the rotating supply body 18 rotates together with the rotating shaft 28 in a state in which the strip oblate 15 and cut oblate 15a are sucked onto the outer surface of the holding part 20 by negative pressure acting on the suction holes 20a, thereby drawing out the strip oblate 15 from the original roll 16 and moving the cut oblate 15a to a supply position S for the tray 11. The rotating supply body 18 is disposed at a height position that allows it to rotate without contacting the tray 11 supported by the transport conveyor 10 with its polygonal corners.

[0019] 5, a drive motor 29 that intermittently rotates the rotary shaft 28 is connected to the rotary shaft 28, and the drive motor 29 is configured to intermittently rotate the rotary shaft 28 at angular intervals of 60° corresponding to the number of holding parts 20 provided on the rotary supply body 18, so that each holding part 20 of the rotary supply body 18 intermittently stops at a downward supply position S, and at this intermittent stop, the cut oblates 15a that are adsorbed to the holding parts 20 at the supply position S are released, so that the cut oblates 15a are dropped and supplied onto the tray 11. The drive motor 29 also rotates the rotary shaft 28 in a direction in which the holding parts 20 of the rotary supply body 18 rotate from the downstream side to the upstream side in the tray conveying direction by the transport conveyor 10 and are positioned at the supply position S. In addition, with respect to the supply position S where the holding part 20 faces downward, as shown in Figure 4, the position where the previous holding part 20 faces upstream of the supply position S in the rotational direction is called the first suction position S1, and the position where the second previous holding part 20 faces is called the second suction position S2.

[0020] As shown in Figs. 4 and 7, the cutting means 19 are disposed on the outside corresponding to each of the rotary feeders 18. That is, the number of cutting means 19 (9 units) is the same as the number of rows of trays 11 transported by the transport conveyor 10, and the cutting means 19 are disposed at equal intervals in the width direction (axial direction of the rotary shaft 28). The cutting means 19 includes a knife 30 and a driving means 31 such as an air cylinder for moving the knife 30 forward and backward relative to the rotary feeder 18. In the cutting means 19, the knife 30 is disposed facing the boundary (between) between the circumferentially adjacent holding parts 20, 20 located at the first suction position S1 and the second suction position S2 when the rotary feeder 18 is in an intermittent stop state. In addition, the rotary feeder 18 has a groove 18a extending in the axial direction, which is recessed toward the center of rotation, between the circumferentially adjacent holding parts 20, 20, and which can receive the knife 30. That is, when the rotary supply body 18 stops intermittently, the knife 30 advances toward the rotary supply body 18, whereby the knife 30 enters the groove 18a and cuts the strip oblate 15 in the width direction, and the cut oblate 15a cut off at a length corresponding to the length of the article storage section 12a in the tray 11 from the tip of the strip oblate 15 is adsorbed onto the outer surface of the holder 20 downstream in the rotation direction from the cutting position. The cutting means 19 of the embodiment is disposed at a position to cut the strip oblate 15 at a position corresponding to the length of the article storage section 12a from the tip of the strip oblate 15 adsorbed on the outer surface of the rotary supply body 18. The cutting means 19 is provided with a pair of support members 32, 32 which move forward and backward integrally with the knife 30, above and below the knife 30, and is configured so that, prior to cutting the strip-shaped oblate 15 with the knife 30, the two support members 32, 32 press the upper and lower cutting positions of the strip-shaped oblate 15 against the holding portions 20, 20 to support them.

[0021] As shown in Figure 5, a switching means 33 is provided on the shaft end of the rotating shaft 28 for switching between an adsorption state in which a negative pressure source is connected to the suction holes 20a of the holding parts 20 located at the supply position S, the first suction position S1, and the second suction position S2 when the rotating supply body 18 is in an intermittent stop state, and a release state in which a negative pressure source is connected to the suction holes 20a of the holding parts 20 located at the first suction position S1 and the second suction position S2, and the negative pressure source is not connected to the suction holes 20a of the holding parts 20 located at the supply position S. Then, the holding portion 20, which is adsorbing the cut oblate 15a separated from the strip oblate 15 at the cutting position, moves from the first adsorption position S1 to the supply position S, and at the timing when the tray 11 is lifted to the receiving position M by the lifting means 21, the switching means 33 switches from the adsorption state to the release state, whereby the adsorption of the holding portion 20 positioned at the supply position S is released and the cut oblate 15a is dropped and supplied to the tray 11.

[0022] 5 and 6, below the upper running portion of the transport conveyor 10, the lifting means 21 for the trays 11 are disposed in correspondence with the lifting position N where the trays 11 transported by the transport conveyor 10 are intermittently stopped below (directly below) the rotary supply body 18. The lifting means 21 are disposed at equal intervals in the width direction, the number of which is the same as the number of rows of the trays 11 transported by the transport conveyor 10 (9 units). Each lifting means 21 comprises a push-up body 34 having a pair of push-up sections 34a, 34a that are spaced apart in the width direction and can pass between each support stay 23, 23 on the conveying conveyor 10, and a lifting means 35 such as an air cylinder for raising and lowering the push-up body 34. The lifting means 35 raises and lowers the push-up body 34 between a retracted position (see solid line in Figure 6) where the push-up sections 34a, 34a are retracted below the underside of the tray 11 being transported on the upper running section of the conveying conveyor 10, and an elevated position (see dashed double-dashed line in Figure 6) where the lifting means 35 supports the width-extending portion of the flange 13 of the tray 11 from below to bring the upper surface of the tray 11 closer to the holding section 20 positioned at the supply position S of the rotating supply body 18.

[0023] 4 and 8, a pressing means 36 for pressing the cut wafers 15a supplied to each tray 11 against the articles 14 contained in the tray 11 is disposed downstream in the tray conveying direction from the position where the rotary supply body 18 is disposed. The pressing means 36 are disposed at equal intervals in the width direction, the number of which is the same as the number of rows of trays 11 conveyed by the conveyor 10 (9 units). Each pressing means 36 includes a pressing body 37 having a plurality of pressing portions 37a protruding downward and capable of contacting the cut oblate 15a, and a lifting means 38 such as an air cylinder for raising and lowering the pressing body 37. The lifting means 38 raises and lowers the pressing body 37 between a retracted position (see solid line in FIG. 6) where the pressing portions 37a are retracted above the upper surface of the tray 11 being transported on the upper running portion of the transport conveyor 10, and a pressing position (see dashed double-dashed line in FIG. 6) where the pressing portions 37a press the cut oblate 15a supplied to the tray 11 against the article 14.

[0024] Next, the operation of the oblate supplying device according to the embodiment will be described. 4, the leading end of the strip oblate 15, which is drawn from each of the original rolls 16 via the auxiliary conveyor 24, is attracted to the outer surface of the holder 20 located at the first suction position S1 and the second suction position S2 of the corresponding rotary feeder 18. When the rotary feeder 18 stops intermittently, the knife 30 of the cutting means 19 advances toward the rotary feeder 18, and the knife 30 enters the groove 18a of the rotary feeder 18, cutting the strip oblate 15 in the width direction at the boundary between the holders 20, 20 located at the first suction position S1 and the second suction position S2. The cut oblate 15a separated from the strip oblate 15 is attracted in a flat state to the outer surface of the holder 20 located at the first suction position S1. Then, the rotary supply body 18 is rotated intermittently, and the holding part 20 at the first suction position S1 moves to the supply position S, so that the cut oblate 15a adsorbed to the holding part 20 is in a flat, downward position at the supply position S. Furthermore, the rotary supply body 18 rotates, so that the strip oblate 15 adsorbed to the holding part 20 located at the second suction position S2 is pulled, and the strip oblate 15 is pulled out from the corresponding original roll 16. The strip oblate 15 is also transported by the suction belt 24a of the auxiliary conveyor 24 that runs intermittently in accordance with the intermittent rotation of the rotary supply body 18, so that the strip oblate 15 pulled out from the original roll 16 is not subjected to a pulling force only to its tip.

[0025] 2, nine rows of trays 11 containing articles 14 are supplied from the previous process to the transport conveyor 10 between the support stays 23, 23 adjacent to each other in the tray transport direction. When each row of trays 11 reaches the lifting position N and the transport conveyor 10 stops intermittently, the push-up body 34 of each lifting means 21 is raised from the retreated position by the elevating means 35, and the flange 13 extending in the width direction of the tray 11 is supported from below by a pair of push-up parts 34a, 34a, and the tray 11 is lifted to the receiving position M where the upper surface of the tray 11 approaches the holding part 20 positioned at the supply position S of the rotary supply body 18 (see the two-dot chain line in FIG. 4). When the tray 11 is lifted to the receiving position M, the switching means 33 switches the rotating supply body 18 from the suction state to the release state, the suction of the cut oblate 15a in the holding part 20 located at the supply position S is released, and the cut oblate 15a is dropped and supplied to the article storage part 12a of the tray 11 at the receiving position M. When the rotating supply body 18 stops intermittently, the strip oblate 15 located on the outer periphery of the rotating supply body 18 is cut in the width direction by the knife 30 of the cutting means 19 at the boundary between the holding parts 20, 20 located at the first suction position S1 and the second suction position S2, as described above. In the release state by the switching means 33, the suction of the strip oblate 15 and the cut oblate 15a in each holding part 20 located at the first suction position S1 and the second suction position S2 is maintained, so that the cut oblate 15a does not fall off from the holding part 20 at the first suction position S1.

[0026] When the lifting means 35 of the lifting means 21 lowers the push-up body 34 from the receiving position M to the retreat position, the tray 11 to which the cut oblate 15a has been supplied is supported at the original position between the support stays 23, 23 on the transport conveyor 10. The rotating supply body 18 is switched from the release state to the suction state by the switching means 33, and the rotating supply body 18 is intermittently rotated by the drive motor 29, so that the cut oblate 15a, which is suctioned to the outer surface of the holding part 20 at the first suction position S1, moves to the supply position S and is positioned there. The strip oblate 15, which is suctioned to the holding part 20 at the second suction position S2, is pulled and pulled out from the original roll 16, so that the strip oblate 15 faces between the first suction position S1 and the second suction position S2. When the rotating supply body 18 is stopped intermittently, the strip oblate 15 is cut in the width direction by the knife 30 of the cutting means 19.

[0027] When the tray 11 on which the cut oblates 15a have been supplied is transported below the pressing means 36 and stops intermittently, the pressing means 36 lowers the pressing body 37 from the retreated position to the pressing position by the lifting means 38 as shown in Fig. 4, and presses the cut oblates 15a supplied to the tray 11 against the articles 14. As a result, the cut oblates 15a adhere to the sticky articles 14, and the cut oblates 15a are maintained in a state of covering the multiple articles 14 contained in the tray 11. Then, the tray 11 on which the cut oblates 15a have been pressed against the articles 14 by the pressing means 36 is transported by the transport conveyor 10 to the next process, such as a packaging process.

[0028] The oblate supplying device of the embodiment can suck the strip-shaped oblate 15 onto the flat holding portion 20 of the rotary supply body 18 and pull it out, and can also suck the cut oblate 15a cut off from the strip-shaped oblate 15 flat onto the holding portion 20 and position it at the supply position S, so that the cut oblate 15a can be supplied in a flat state to the article storage portion 12a of the tray 11. That is, the strip-shaped film 15 pulled out from the original roll 16 by the rotation of the rotary supply body 18 does not become curved, and it is possible to prevent only a part of the cut oblate 15a from contacting the article 14 stored in the tray 11 first, and it is possible to prevent the cut oblate 15 from curling. Therefore, it is possible to prevent the article 14 stored in the tray 11 from drying out by the cut oblate 15a, and it is possible to prevent the occurrence of problems in the subsequent process caused by the cut oblate 15a supplied to the tray 11. Furthermore, when the cut oblates 15a are supplied to the tray 11, the tray 11 is lifted from the transport conveyor 10 and brought close to the holder 20 positioned at the supply position S, so that the cut oblates 15a separated from the holder 20 by the release of suction can be supplied to an appropriate position in the article storage section 12 of the tray 11. In other words, the movement of the lightweight cut oblates 15a in the front-back and left-right directions while falling can be suppressed, and the cut oblates 15a can be supplied to an appropriate position in the article storage section 12.

[0029] The oblate supplying device of the embodiment includes the roll support portion 17 for supporting the original roll 16 of the strip oblate 15, the rotary supply body 18, the cutting means 19, the lifting means 21, and the pressing means 36, the number of which is the same as the number of rows of the trays 11 transported by the transport conveyor 10, so that a plurality of cut oblates 15a can be supplied to a plurality of trays 11 at once, improving the processing capacity. Furthermore, since the cutting means 19 is provided corresponding to each rotary supply body 18, even if the tension of the strip oblate 15 adsorbed on the outer surface of each rotary supply body 18 is different, the corresponding strip oblate 15 can be appropriately cut. Furthermore, the cutting means 19 cuts the strip oblate 15 by inserting the knife 30 into the groove 18a of the rotary supply body 18, so that the soft strip oblate 15 can be cut well. Furthermore, the cutting means 19 cuts the band-shaped oblate 15 with the knife 30 while the support members 32, 32 press the band-shaped oblate 15 against the holding portion 20 on both sides of the cutting position of the band-shaped oblate 15, so that the band-shaped oblate 15 can be cut more efficiently.

[0030] In the oblate supplying device of the embodiment, an auxiliary conveyor 24 capable of transporting the oblate strip 15 is disposed in the transport path of the oblate strip 15 between the roll support parts 17 and the rotary supply body 18, and the auxiliary conveyor 24 and the rotary supply body 18 pull out the oblate strip 15 from the original roll 16, dispersing the pulling force applied to the oblate strip 15 and preventing breakage of the oblate strip 15. Also, since the roll support parts 17, the number of which corresponds to the number of rows of trays 11 transported by the transport conveyor 10, are distributed in the tray transport direction, the width dimension can be made smaller than when all the roll support parts 17 corresponding to the number of rows of trays 11 are arranged side by side in the horizontal direction, and the oblate supplying device can be made more compact. In addition, since the cut oblate 15a supplied to the tray 11 is pressed by the pressing means 36 so as to adhere to the object 14, the object 14 and the cut oblate 15a can be brought into close contact with each other, and drying of the object 14 can be suppressed. Furthermore, by bringing the cut oblate 15a into close contact with the object 14, the cut oblate 15a can be prevented from rolling up when the tray 11 is transported to the next process.

[0031] (Example of change) The present invention is not limited to the configurations of the examples, and can be modified as follows, for example. Furthermore, the configurations described in the examples are not limited to the following modifications, and various embodiments can be adopted within the scope of the gist of the present invention. (1) The number of the holding parts 20 provided on the rotary supply body 18 is not limited to six, and may be three or more. The rotary supply body 18 may have a shape in which the outer periphery between the circumferentially adjacent holding parts 20, 20 is formed in an arc shape, or the holding parts 20 are provided on supports provided radially on the rotary shaft 28, and a receiving part for the knife 30 is provided in the space between the circumferentially adjacent holding parts 20, 20. In this way, various shapes can be adopted that can adsorb the strip-shaped oblate 15 to each of the holding parts 20 provided at a distance in the circumferential direction and cut the strip-shaped oblate 15 between the circumferentially adjacent holding parts 20, 20. (2) The number of roll support portions 17 (supply sources), rotating supplies 18, cutting means 19, lifting means 21, and pressing means 36 may correspond to the number of rows of trays 11 transported by the transport conveyor 10, and may be one or more than two. (3) The pressing means 36 may be provided depending on conditions such as the properties of the articles 14 and the shape of the article storage section 12a in the tray 11, and may be omitted depending on conditions. (4) When the suction of the holding portion 20 on the rotating supply body 18 is released, an air blowing means for blowing air in a direction to move the cut oblate 15a away from the holding portion 20 can be provided in the holding portion 20, and a configuration can be adopted in which the air blowing means actively causes the cut oblate 15a to fall from the holding portion 20.
