Description

The present invention relates to a processing device for rimmed containers that can align the orientation of rimmed containers that have a rim on the top of the container body, such as portion packs.

A device for dividing and supplying items has been proposed for use in tray packing machines that pack rimmed containers, such as food containers called portion packs, which are single-serving, single-pack packages of food and beverages such as jam, marmalade, coffee milk, gum syrup, jelly, and dressing, into trays (see, for example, Patent Document 1). The trays used by the device for dividing and supplying items disclosed in Patent Document 1 have preformed recesses for accommodating the container bodies of the portion packs, spaced apart so that the rims of the portion packs do not interfere with each other. The portion packs, which are being pushed together and conveyed by a conveyor, are divided into a predetermined number of pieces, and the spacing between the divided portion packs is expanded to correspond to the spacing between the recesses before being accommodated in the tray.

Japanese Utility Model Publication No. 60-40404

In the divided supply device disclosed in Patent Document 1, the intervals at which the portion packs are stored on the tray are set wide so that the flanges do not interfere with each other, which causes the problem that the tray size required for storage becomes large and bulky. For this reason, when multiple trays are packed together in a case, the size of the outer box must be selected to be correspondingly large, which leads to problems with high material costs and transportation costs. In addition, if portion packs with part of the flange protruding are stored in a storage container such as a tray in groups of multiple portions, and the flange protrudes outside the storage container during the process of transporting the storage container and is sent to a subsequent process, the protruding part may get in the way when handled by various processing machines, making it impossible to process properly, or the portion packs may come into contact with the structure of the processing machine when passing through the processing machine, causing the portion packs stored in the container to fly out.

The object of the present invention is to provide a processing device for rimmed containers that can align the orientation of the rimmed containers and reduce the size of the assembled container.

The processing device for a flanged container according to the invention of claim 1 of the present application comprises:
A treatment device for a flanged container having a flange (14) on an upper portion of a container body (13), comprising:
The flange (14) has a protruding portion (14a) that protrudes outward and enables the orientation of the container to be identified in a plan view,
a transport conveyor ( 15) that is provided at predetermined intervals with a plurality of support parts (24) each having a groove (26) into which the flange (14a) is fitted in a predetermined orientation, and that is capable of supporting and transporting a flanged container (10) on each support part (24);
an imaging means (16) for imaging the flange (14) of the flanged container (10) supported and transported by the support portion (24) of the transport conveyor (15);
a detection means (22) for detecting the orientation of the flange (14) of the flanged container (10) based on image information of the flange (14) captured by the imaging means (16);
a plurality of orientation correcting means (18) for lifting the flanged container (10) from the plurality of supports (24), rotating the container about a vertical axis, and then lowering the container to the support (24);
The present invention is characterized in that, based on the orientation of the flange (14) detected by the detection means (22), the orientation correction means (18) is used to align and fit the flange (14) of each flanged container (10) so as to match the shape of each groove portion (26) of the support portion (24).
According to the invention of claim 1, the flanges of the flanged containers detected by the detection means are fitted in the grooves of the support parts provided on the transport conveyor with the flanges aligned, so that when a plurality of flanged containers are gathered together with the same orientation, the flanges can be aligned so that the outer edge size is small. This allows a storage container size such as a tray with a small capacity to be selected when packing directional flanged containers into a storage container such as a tray. In addition, the size of the outer box when packing a plurality of storage containers such as tray-packed products together in a box can be reduced, so that not only the cost of packaging materials but also the transportation cost can be reduced. Furthermore, since the flanges of the flanged containers can be delivered to the next process with the flanges aligned, by storing the flanged containers in such a way that they do not protrude outside the storage container, it is possible to prevent problems such as the flanges coming into contact with the structure of the processing machine when passing through the post-processing machine, causing the flanged containers to fly out of the storage container, or preventing proper processing by the post-processing machine from being hindered.

In the invention according to claim 2, a part of the flange (14) of the flanged container (10) has the protruding portion (14a) protruding outward,

Next, a preferred embodiment of the processing device for flanged containers according to the present invention will be described below with reference to the attached drawings.

The embodiment of the processing device for brimmed containers shown in Figures 1 and 8 is a device that transfers multiple brimmed containers 10 transported from a previous process such as a manufacturing machine onto a tray 12 as a grouped container 11 (brimmed containers 10 grouped in multiple rows) with the containers 10 aligned in the same direction. The brimmed container 10 is exemplified as a portion pack 10 in which a brimmed container body 13 containing food or drink is provided at the top of the container body 13 with a brimmed container body 13 to which a lid is sealed, and the brimmed container 14 is formed in a shape that allows the orientation of the brimmed container 10 to be specified in a plan view. In the embodiment, the brimmed container 14 is exemplified as a directional shape with a protruding portion 14a that protrudes outward and serves as an opening knob. The processing device comprises a conveying conveyor 15 which conveys the portion packs 10 in multiple rows and multiple columns spaced apart at a predetermined distance, an imaging means 16 which images the flanges 14 of the portion packs 10 in the multiple rows and columns transported by the conveying conveyor 15, a detection unit 22 which acts as a detection means for detecting the orientation of the flanges 14 (the protruding direction of the protrusion 14a) of the portion packs 10 based on image information obtained by image processing of the data imaged by the imaging means 16, and an orientation correction means 18 which corrects the orientation of the flanges 14 of each portion pack 10 transported by the conveying conveyor 15 based on the orientation of the flanges 14 detected by the detection unit 22 so that it matches the shape of a groove portion 26 formed in a support portion 24 of the conveying conveyor 15 described later. The processing device also includes a handling means (first handling means) 19 that adsorbs and picks up from the conveyor 15 the multiple rows and columns of portion packs 10 whose flanges 14 have been aligned by the orientation correction means 18 and that have been conveyed by the conveyor 15; a placement table 20 onto which the multiple rows and columns of portion packs 10 picked up by the handling means 19 are transferred; and a robot hand (second handling means) 23 that adsorbs and picks up the multiple rows and columns of portion packs 10 placed on the placement table 20 and transfers them to a tray 12 on a tray conveyor 21.

1 to 4, the transport conveyor 15 is a conveyor that circulates a carrier 25 having support parts 24 capable of supporting portion packs 10 one by one, which are provided at predetermined intervals in the front and rear of the article transport direction (column direction) and in the left and right of the width direction (row direction) intersecting with the article transport direction, and is configured to support and transport portion packs 10 in multiple rows (four rows in this embodiment). The support parts 24 of the carrier 25 are provided with through holes 24a through which the container body 13 below the flange 14 of the portion pack 10 can pass, and at the upper end of the through holes 24a, a groove part 26 is formed on the carrier surface side and into which the flange 14 of the portion pack 10 can fit, and the portion pack 10 is configured to be supported by the support parts 24 with the flange 14 fitting into the groove part 26 and the container body 13 suspended within the through hole 24a. The groove 26 is formed in a shape that matches the outer shape of the flange 14, and the extension 26a into which the protrusion 14a of the flange 14 fits is formed to extend in a direction away from the through hole 24a, and the rotation of the portion pack 10 is restricted by the protrusion 14a fitting into the extension 26a (see FIG. 11(c)). As shown in FIG. 11(c), the extension 26a of the groove 26 is formed in a protruding direction such that the protrusion 14a fitting into the extension 26a is within the range of imaginary tangents N, N that extend in the row direction and are in contact with the outer circumference of the flange 14 excluding the protrusion 14a.

In the embodiment, the support portions 24 are formed so that the extending portions 26a of the first and second rows, counting from one side in the width direction of the transport conveyor 15, are oriented in pairs, and the extending portions 26a of the third and fourth rows are oriented in pairs. The extending portions 26a of the groove portions 26 of the first row and the extending portions 26a of the groove portions 26 of the second row are formed to extend on the other support portion side of the pair, and the extending portions 26a of the groove portions 26 of the third row and the extending portions 26a of the groove portions 26 of the fourth row are formed to extend on the other support portion side of the pair. In the embodiment, the extension portions 26a of the groove portions 26 in the first and third rows extend diagonally toward the upstream side in the item transport direction, while the extension portions 26a of the groove portions 26 in the second and fourth rows extend diagonally toward the downstream side in the item transport direction, and by narrowing the row spacing (the spacing between adjacent rimmed containers in the same column) and column spacing (the arrangement spacing, which is the spacing between adjacent rimmed containers in the same row) of the portion packs 10 aligned in the direction so that the rims 14 fit into the groove portions 26, the protrusion portion 14a of the rim 14 of one portion pack 10 adjacent in the row and column directions can overlap vertically with a portion of the rim 14 of the other portion pack 10. The transport conveyor 15 is driven so that the carrier 25 intermittently stops at the imaging position S1 by the imaging means 16, the orientation alignment position S2 by the orientation correction means 18, and the pickup position S3 by the handling means 19 to pick up multiple columns and rows (five rows in this embodiment) of portion packs 10 that are adsorbed and picked up all at once by the handling means 19.

As shown in FIG. 1, the imaging means 16 equipped with other image sensors, such as a CCD camera equipped with multiple lenses capable of imaging the flanges 14 of the portion packs 10 on the carrier from above, is provided along the conveying conveyor 15. When the conveying conveyor 15 stops intermittently, the imaging means 16 images multiple rows and multiple columns (five rows and four columns in this embodiment) of portion packs 10 located at the imaging position S1 and picked up by the handling means 19 at once, and the image information obtained by imaging by the imaging means 16 is input as a signal to the control means 17 of the processing device and image-processed, and the direction of the flanges 14 of each portion pack 10 (the protruding direction of the protruding portion 14a) is detected by the detection unit 22 of the control means 17. In addition, the imaging means 16 is provided with lighting means 27 around the camera lens that images the five rows and four columns of portion packs 10 that are intermittently stopped at the imaging position S1, providing a predetermined illuminance suitable for imaging.

As shown in FIG. 1, the orientation correction means 18 is disposed downstream of the position where the imaging means 16 is disposed, below the upper running part of the carrier 25 of the conveyor 15. As shown in FIG. 2 to FIG. 4, the orientation correction means 18 includes a rotating pipe (rotating member) 29 having a suction cup 28 as an adsorption part at its upper end and extending in the vertical direction (vertical direction), and an orientation correction motor (motor) 30 consisting of a servo motor that rotates the rotating pipe 29 forward and backward around an axis in the vertical direction (around a vertical axis). The orientation correction means 18 is disposed at a position corresponding to each of the five rows and four columns of support parts 24 that stop intermittently at the orientation alignment position S2. The lower end of each rotating pipe 29 is connected to a suction source, and is configured to be able to adsorb the underside of the portion pack 10 suspended and supported by the support part 24 by the negative pressure generated in each suction cup 28. The orientation correction means 18 also includes a movement mechanism 31 that raises and lowers the rotating pipe 29, and the movement mechanism 31 raises and lowers the suction cup 28 between a retracted position (see Figures 2 and 3) where it is retracted below the bottom surface of the portion pack 10 that is suspended and supported by the support portion 24, and a correction position (see Figure 4) where the flange 14 of the portion pack 10 that has adsorbed the bottom surface faces upward from the groove portion 26.

2 to 4, in the embodiment, the orientation correction means 18 are arranged side by side in correspondence with the number of support parts 24 in one row (four in the embodiment), and a plurality of correction units 32 (five in the embodiment) configured to raise and lower the rotating pipes 29 of the orientation correction means 18 for each row as a unit by a moving mechanism 31 are arranged in the article conveying direction. The moving mechanism 31 includes a support member 33 on which the four rotating pipes 29 are rotatably supported, and an air cylinder 35 arranged on the device frame 34 to raise and lower the support member 33, and the suction cup 28 of the correction unit 32 is raised and lowered between the retracted position and the correction position by the air cylinder 35. The orientation correction motor 30 connected to the rotating pipe 29 by a gear transmission mechanism 36 is arranged on each support member 33 in correspondence with the number of the rotating pipes 29 arranged, and is configured to rotate each rotating pipe 29 individually in the forward and reverse directions. Then, the control means 17 controls the rotation of the orientation correction motor 30 in accordance with the orientation of the flange 14 detected by the detection unit 22 to rotate the rotating pipe 29 and rotate the portion pack 10 adsorbed by the suction cup 28, thereby aligning the orientation of the flange 14 to match the orientation of the groove portion 26. In the embodiment, the correction units 32 in each row adjacent to each other in the article conveying direction are arranged with the lifting drive units shifted in the vertical direction (alternately) so that the support members 33 can be raised and lowered without interfering with each other, and the lifting drive units are configured to reduce the arrangement space in the article conveying direction for the multiple orientation correction means 18 without contacting and interfering with each other.

1, 5 and 6, the handling means 19 is disposed downstream of the position where the orientation correction means 18 is disposed, which picks up from the carrier 25 a plurality of rows and a plurality of columns (five rows and four columns) of portion packs 10 that have been aligned by the orientation correction means 18 and transported by the transport conveyor 15. The handling means 19 includes a lifting member 37 supported on the device frame 34 so as to be movable in the vertical direction, a reference support member 39a disposed on the lifting member 37, a plurality of slide members 39b (four in the embodiment) disposed in front and behind the reference support member 39a in the article transport direction and movable forward and backward in the article transport direction, and a row spacing change means 40 which moves each slide member 39b forward and backward in the article transport direction relative to the reference support member 39a. The reference support member 39a and the slide member 39b are each provided with four rows of suction cups 38 as suction sections, and the mutual intervals (row intervals) of the suction cups 38 arranged on the reference support member 39a and the slide member 39b are changed by moving each slide member 39b back and forth in the article conveying direction relative to the reference support member 39a using a row interval changing means 40. The handling means 19 also includes a lifting mechanism 41 that moves the lifting member 37 up and down. The lifting mechanism 41 employs a linear operating mechanism that servo-controls an electric actuator 41a, and is configured to raise and lower the lifting member 37 to position the suction cup 38 at an adsorption position where it can adsorb the top surface (upper surface) of the portion pack 10 supported by the support portion 24 of the carrier 25 on the transport conveyor 15, a transfer position where it can transfer the portion pack 10 to the loading platform 20 positioned above the adsorption position at a receiving position (dashed line position in Figure 5) S4 described later, and a retracted position above the transfer position. When five rows and four columns of portion packs 10 are transported by the transport conveyor 15 to the pick-up position S3 and stopped intermittently, the handling means 19 lowers the lifting member 37 from the retracted position to the suction position, and each suction cup 38 adsorbs the top surface (upper surface) of the corresponding portion pack 10, and then rises to the retracted position, thereby picking up five rows and four columns of portion packs 10 from the transport conveyor 15 all at once.

As shown in FIG. 6, the line spacing change means 40 provided in the handling means 19 has a plurality of slide shafts 42 extending along the article transport direction arranged on the lifting member 37, the reference support member 39a is fixed in position at the longitudinal center of the slide shafts 42, and two slide members 39b are supported in front of and behind the reference support member 39a so as to be freely movable along the slide shaft 42.

The placement surfaces 51, 52 have a step with a height difference such that the upper surface of the flange 14 of the portion pack 10 placed on the second placement surface 52 is located lower than the lower surface height of the flange 14 of the portion pack 10 placed on the first placement surface 51. In addition, a restriction portion 53 is provided in the center of the placement table 20, protruding from the first placement surface 51, for restricting the movement of the portion pack 10 placed on the first placement surface 51 toward the center.

7 to 9, the row spacing change means 47 includes pushers 54 arranged on both sides of the placement table 20 in the width direction, and an air cylinder 55 as an actuating means for moving each pusher 54 forward and backward. The pushers 54 are formed of thin, flat plates capable of pushing the container bodies 13 directly below the flanges 14 of multiple (five in this embodiment) portion packs 10 placed on the second placement surface 52 and lined up in the item conveying direction. The pusher 54 is configured to move back and forth between a retracted position (dashed line position in Figure 9) spaced away from the outside of the portion packs 10 placed on the second loading surface 52 and arranged in the item transport direction, and a width-adjusted position (solid line position in Figure 9) moved toward the center in the width direction from the retracted position.By moving the pusher 54 from the retracted position to the width-adjusted position, the pusher 54 pushes the container bodies 13 of five portion packs 10 arranged in a row on the second loading surface 52 of the loading table 20, and brings the lower surfaces of the flanges 14 of the five portion packs 10 placed in a row on the first loading surface 51 close to the upper surfaces of the flanges 14 of the five portion packs 10 pushed on the second loading surface 52 in a vertical relationship. That is, the column spacing change means 47 narrows the column spacing of multiple columns of portion packs 10 that are placed on the placement table 20 and have already been narrowed by narrowing the spacing between adjacent portion packs 10, 10 in the same row that are placed on the first and second placement surfaces 51, 52 of each assembly section 61 and then collecting them.

As shown in Figures 7 and 8, the tray conveyor 21 is arranged parallel to one side of the transport conveyor 15 and is arranged to transport the trays 12 in the opposite direction to the item transport direction of the transport conveyor 15, and the transfer position at which the trays 12 stop being transported is set corresponding to the transport end side of the transport conveyor 15. The tray 12 in the embodiment is set to a size that can accommodate two stacked collection containers 11 that are assembled with five rows and two columns of portion packs 10 with narrow row and column spacing.

1 and 7, a parallel link robot equipped with a robot hand 23 having a holding means 57 at the end of a robot arm 56 is disposed above the placement table 20 in the retracted position. The holding means 57 has suction cups 59 arranged on each of two support members 58, 58 spaced apart in the width direction as suction sections capable of adsorbing five rows and two columns of portion packs 10. The spacing between the multiple suction cups 59 arranged on each support member 58 is set to a spacing that allows the cups to adsorb the top surfaces of the portion packs 10 in the collection containers 11 that are assembled with narrow row and column spacing. In addition, the distance between the two support members 58, 58 is set so that in the process of suctioning the portion packs 10 with one support member 58 and packing them into a tray, and then packing the portion packs 10 sucked by the other support member 58 into the tray, the portion packs 10 sucked by the suction cups 59 can be transferred in two layers without interfering with the trays 12, or can be transferred without hindrance to each tray 12 that is transported sequentially.

The robot hand 23 is configured to move the holding means 57 up and down and left and right, to pick up two collection containers 11, 11 with narrow row and column spacing placed on the placement table 20 at once, and to transfer the collection container 11 picked up by one of the support members 58, 58, which is picked up by the suction cups 59 of both support members 58, 58, to the tray 12 positioned at the transfer position as the first tier, and then transfer and pack the collection container 11 picked up by the other support member 58 to be stacked as the second tier on the same tray 12. In the embodiment, the robot hand 23 is configured to transfer the collection containers 11 picked up by the support members 58 separately to the tray 12 in the order from the side close to the tray conveyor 21 to the side away from it.

10, the control means 17 of the processing device is electrically connected to the orientation correction motors 30 and air cylinders 35 of the orientation correction means 18, the electric actuator 41a of the handling means 19, the servo motor 44 of the row spacing change means 40, the drive motor 49 of the temporary placement device 45, the air cylinders 55, 55 of the column spacing change means 47, and the robot control unit 60 of the robot hand 23. The imaging means 16 is also connected to the control means 17. Then, the control means 17 detects the orientation of the flange 14 (the protruding direction of the protrusion 14a) of each portion pack 10 by the detection unit 22 based on the image information obtained by the imaging means 16, and for each portion pack 10 in which the orientation of the flange 14 is not aligned to match the orientation of the groove 26, determines the amount of rotation (rotation angle) and rotation direction of each orientation correction motor 30 that rotates the suction cup 28 integrated with the rotating pipe 29 to align the protrusion 14a of the flange 14 with the extending direction of the extension 26a in the groove 26. The rotation direction is determined to be the direction in which the amount of circumferential deviation (deviation angle) between the extension 26a and the projection 14a is small. That is, if the amount of clockwise deviation of the protrusion 14a relative to the extension 26a is less than 180°, the control means 17 controls the rotation of the orientation correction motor 30 to rotate the rotating pipe 29 and the suction cup 28 in the counterclockwise direction, and if the amount of counterclockwise deviation of the protrusion 14a relative to the extension 26a is less than 180°, the control means 17 controls the rotation of the orientation correction motor 30 to rotate the rotating pipe 29 and the suction cup 28 in the clockwise direction. Note that when the amount of deviation of the protrusion 14a relative to the extension 26a is 180°, either the clockwise or counterclockwise direction is acceptable, but in the embodiment, it is set to rotate in the clockwise direction.

Next, the operation of the treatment device for a flanged container according to the embodiment will be described.
11(b), the portion packs 10 are transferred from the previous process onto the transport conveyor 15 in a random state in which the orientation of the flanges 14 is not fixed, so that the container bodies 13 are inserted into the through holes 24a of each support part 24. That is, on the carrier of the transport conveyor 15, there are a mixture of portion packs 10 that are suspended and supported by the support parts 24 with the flanges 14 fitted into the grooves 26, and portion packs 10 that are suspended and supported by the support parts 24 with the flanges 14 not fitted into the grooves 26 but caught on the upper surface of the carrier.

When the transport conveyor 15 reaches the imaging area of the portion packs 10 and stops intermittently, the five rows and four columns of portion packs 10 stopped at the imaging position S1 are imaged from above by the imaging means 16, the image information captured by the imaging means 16 is image-processed by the control means 17, and the orientation of the flange 14 of each portion pack 10 is detected by the detection unit 22 of the control means 17. Based on the detected orientation of the flange 14, the control means 17 determines the direction of rotation and the amount of rotation to correct the orientation of each portion pack 10 whose flange 14 is not fitted into the groove 26 of the support part 24 and whose orientation is misaligned, only for those portion packs 10 whose flange 14 is detected to be misaligned.

When the five rows and four columns of portion packs 10 imaged by the imaging means 16 are transported by the transport conveyor 15 and intermittently stopped at the orientation alignment position S2, the suction cups 28 are raised from their retracted positions by the movement mechanism 31 of the orientation correction means 18, as shown in Fig. 4, and the suction cups 28 adsorb the undersides of the portion packs 10 suspended and supported by the respective supports 24, lifting the portion packs 10 to a correction position where the flanges 14 face above the grooves 26. Then, each of the orientation correction motors 30 corresponding to the rotating pipes 29 of the suction cups 28 that adsorb the portion packs 10 whose flanges 14 have been detected to be misaligned with respect to the grooves 26 of the supports 24 is controlled to rotate the suction cups 28 together with the rotating pipes 29 by the calculated amount of rotation in the direction of rotation determined by the control means 17. When the orientation of the portion packs 10 is corrected, the suction cups 28 are moved by the moving mechanism 31 from the corrected position where the flanges 14 are raised from the grooves 26 to a retracted position where the flanges 14 are lowered below the grooves 26, and the suction force of the suction cups 28 is released. Then, the flanges 14 of each portion pack 10 whose orientation has been corrected fit into the corresponding grooves 26, and the portion packs 10 are supported by being hung from the respective supports 24 with their orientations aligned (see FIG. 11(c)). Note that for portion packs 10 whose flanges 14 are not misaligned, the correction motor 30 does not rotate the rotating pipes 29. Furthermore, the portion packs 10 move up and down while being adsorbed to the suction cups 28, and the suction is released, so that the flanges 14 fit into the grooves 26 again.

When the five rows and four columns of portion packs 10 whose orientation has been aligned by the orientation correction means 18 are transported by the transport conveyor 15 to the pick-up position S3 and stopped intermittently, the handling means 19 lowers the suction cups 38 of the reference support member 39a and slide member 39b, which are positioned in the separated position in the retracted position by the lifting mechanism 41, to the suction position, and adsorbs the top surface (upper surface) of the portion packs 10 supported by each support portion 24 on the carrier 25. Then, while the lifting mechanism 41 raises the suction cups 38 to a retracted position, the handling means 19 uses the row spacing change means 40 to move the four slide members 39 to a close position, narrowing the spacing between adjacent portion packs 10 in the front and rear of the item transport direction (column direction) that are being adsorbed to the suction cups 38, thereby narrowing the spacing between the five rows of portion packs 10 until the flanges 14, 14 overlap in the vertical direction (see solid lines in Figure 5).

When the suction cups 38 of the handling means 19 rise to the retracted position, the temporary placement device 45 moves the placement table 20 from the retracted position S5 to the receiving position S4 by the advance/retract mechanism 46, as shown in Figures 5 and 8. The handling means 19 also lowers the suction cups 38 of the slide member 39b and the suction cups 38 of the reference support member 39a, which are positioned in the approaching position, to the delivery position, releases the suction of the suction cups 38, and transfers five rows and four columns of portion packs 10 with narrowed row spacing to the placement table 20. At this time, the second and third rows of portion packs 10 are transferred to the first placement surfaces 51, 51 on the center side of the placement table 20, and the first and fourth rows of portion packs 10 are transferred to the second placement surfaces 52, 52 away from the center. After releasing the suction of the suction cup 38, the handling means 19 uses the line spacing change means 40 to move the slide member 39b to the separated position and raises the suction cup 38 to the retracted position, waiting to pick up the next portion pack 10.

The temporary placement device 45, in which the portion packs 10 have been transferred from the handling means 19 to the placement table 20, moves the placement table 20 to the retracted position S5 by the advancing/retreating mechanism 46, and moves each pusher 54 of the row spacing change means 47 from the retracted position to the width-adjusting position. As a result, as shown in FIG. 9, one row of portion packs 10 placed on each second placement surface 52 of the placement table 20 is pushed by the pusher 54 and approaches one row of portion packs 10 placed on the first placement surface 51, which has a height difference, narrowing the space between adjacent portion packs 10 in the row direction in the assembly section 61, and the flanges 14, 14 of both portion packs 10, 10 overlap in the vertical direction to form an assembly state. That is, on the mounting table, two collection containers 11, 11 are formed in the collection sections 61 on both the left and right sides of the center, with the two rows of portion packs 10 gathered together so that the row and column spacing is narrowed. Note that the five portion packs 10 placed on the second mounting surface 52 in each collection section 61 are guided by the partition 62 when pushed by the pusher 54, and the two rows of portion packs 10 are gathered in an aligned state. Also, the portion packs 10 placed on the first mounting surface 51 are restricted from moving toward the center by the restriction section 53, and the two collection containers 11, 11 are positioned at a predetermined distance apart.

When the two collection containers 11, 11 are formed by the row spacing change means 47, the robot hand 23 lowers the support members 58, 58 of the holding means 57 above the placement table 20, adsorbs the collection containers 11 consisting of five rows and two columns of portion packs 10 with the suction cups 59 of each support member 58, and lifts the suction cups 59 to pick up the two collection containers 11, 11 all at once from the placement table 20. The robot hand 23 that has picked up the collection containers 11, 11 moves one of the collection containers 11 that is adsorbed by the suction cups 59 of one of the support members 58 of the holding means 57 (the side close to the tray conveyor 21 in this embodiment) to above the tray 12 stopped at the transfer position and lowers it, transferring the one collection container 11 so that it is packed into the first stage of the tray 12. Then, the holding means 57 is raised and moved in the width direction, and the other collection container 11 that is being sucked by the suction cup 59 of the other support member 58 is transferred so as to be packed into the second tier of the same tray 12. Then, the collection containers 11 are stacked in two tiers, one above the other, on the tray 12 (see FIG. 7). After transferring the two collection containers 11, 11 to the tray 12, the robot hand 23 returns the holding means 57 to above the mounting table 20 and waits to pick up the next collection container 11. The row spacing change means 47 maintains the pusher 54 in the width-pushing position to support the portion pack 10 until the collection container 11 is picked up by the robot hand 23, and then moves the pusher 54 to the retreat position.

In the embodiment of the processing device for flanged containers, the flanges 14 of the portion packs 10 are fitted into the grooves 26 of the support parts 24 provided on the transport conveyor 15 with the orientation of the flanges 14 aligned, so that the spacing between the portion packs 10 arranged in multiple rows can be narrowed to reduce the aggregate size (outer edge size) of the aligned portion packs 10. This makes it possible to select a tray size with a small capacity when packing directional portion packs 10 into a tray 12. In addition, the size of the outer box can be reduced when packing multiple storage containers such as tray-packed products together, which not only reduces packaging material costs and transportation costs but also contributes to reducing the environmental impact. Furthermore, since the flanges 14 of the portion packs 10 can be aligned when they are handed over to the next process, by storing the portion packs 10 aligned so that their flanges 14 do not protrude outside the tray 12, it is possible to prevent problems such as the flanges 14 coming into contact with the structure of the post-processing machine when passing through it, causing the portion packs 10 to fly out of the tray 12, or preventing proper processing by the post-processing machine from occurring.

The extension portion 26a of the groove portion 26 in each row is arranged so that the protrusion 14a on the flange 14 that fits into the extension portion 26a faces the portion pack in the adjacent column. Therefore, by aligning and assembling the portion packs 10 in adjacent columns, the portion packs 10, 10 are not assembled in a state where the protrusion 14a faces the side opposite to the side they face, and the size in the row direction (width direction) when assembled can be reduced. In addition, the extensions 26a of the grooves 26 in each row are provided so that the protrusions 14a on the flanges 14 that fit into the extensions 26a face one of the adjacent portion packs in the same row. Therefore, by aligning and assembling the portion packs 10 in adjacent rows, the portion packs 10 are not assembled in a state in which the protrusions 14a face the opposite sides of the portions 10, 10 that face each other, so that the size in the column direction (the direction of conveying the goods) in the assembled state can be reduced. In addition, when narrowing the row and column spacing of the portion packs 10 in multiple rows and columns, the flanges of the adjacent portion packs 10 are assembled so that they overlap vertically, so that the size in the row and column directions of the trays 12 can be reduced, and the size of the outer box when the tray-packed products are packed together in a box can also be reduced, so that the packaging material costs and transportation costs can be reduced.

In the embodiment of the processing device for flanged containers, the orientation correction means 18 corrects the orientation of the portion pack 10 by rotating the portion pack 10 in a direction that minimizes the misalignment between the extension 26a of the groove 26 and the protrusion 14a of the flange 14, so that the orientation alignment work of the portion pack 10 can be performed in the shortest time. In addition, since the placement table 20 is moved to the receiving position S4 and the retreating position S5, the placement table 20 to which the portion pack 10 has been transferred from the handling means 19 at the receiving position S4 can be moved to the retreating position S5, so that the next portion pack 10 can be picked up by the handling means 19, thereby improving processing efficiency. Furthermore, since the two collection containers 11, 11 are collected on the placement table 20 so as to be lined up at a predetermined distance, the two collection containers 11 picked up by the robot hand 23 can be transferred to the tray 12 in a stacked state in a good condition. In addition, the row spacing changing means 47 pushes the plurality of portion packs 10 placed on the lower second mounting surface 52 formed on the mounting base 20 and having a step in height so as to approach the plurality of portion packs 10 placed on the higher first mounting surface 51 with the pusher 54, thereby gathering two rows of portion packs 10, thereby narrowing the row spacing of the plurality of rows of portion packs 10 with a simple configuration. In addition, on the second mounting surface 52 of the mounting base 20, the portion packs 10 of each row are placed on each row partition section 63 partitioned by partitions 62, so that when pushed by the pusher 54, the portion packs 10 of each row are guided by the partitions 62 and two rows of portion packs 10 are gathered in an aligned state, and the collection container 11 can be smoothly packed into the tray 12 without the flange 14 interfering with the opening edge of the tray 12. Furthermore, the robot hand 23 picks up the multiple collected containers 11 all at once and transfers each of the collected containers 11 to the tray 12 in a stacked state, so the transfer work can be carried out efficiently.

In the embodiment of the processing device for rimmed containers, the row spacing of the multiple rows and columns of portion packs 10 picked up from the transport conveyor 15 is narrowed by the row spacing change means 40 of the handling means 19, and the column spacing of the multiple rows and columns of portion packs 10 transferred to the loading platform 20 is narrowed by the column spacing change means 47, and the assembled containers 11 with narrowed row and column spacing are transferred to the tray 12 by the robot hand 23. Therefore, by distributing each process, the cycle time can be shortened and processing efficiency can be improved, and the assembled containers 11 can be efficiently transferred to the tray 12.

(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) In the embodiment, the support portion 24 provided on the carrier 25 of the transport conveyor 15 is a hole penetrating in the vertical direction, but it may be a bottomed hole. If the support portion 24 is a bottomed hole, a configuration may be adopted in which the orientation correction means 18 is disposed above the transport conveyor 15 and the suction cup 28 suctions the upper surface of the portion pack 10 to lift it up and rotate it, thereby correcting the orientation.
(2) The orientation correction means 18 in the embodiment is configured to raise and lower the rotating pipes 29 in units of one row, but the number of rotating pipes 29 to be raised and lowered can be set arbitrarily, such as in units of multiple rows, one column, or multiple columns. Also, a configuration can be adopted in which the rotating pipes 29 are raised and lowered individually, and in this configuration, it is possible to handle this by raising and lowering only the rotating pipes 29 that correspond to the portion packs 10 whose orientation needs to be corrected.
(3) The rotating member 29 of the direction correcting means 18 is not limited to a rotating pipe 29 but may be a solid shaft member, and the suction cup 28 provided at the end thereof may be configured to provide a suction effect.
(4) Although the spacing between the rows of the portion packs 10 transferred onto the platform 20 is narrowed by the row spacing changing means 47, the row spacing changing means 47 may be employed as needed.
(5) When transferring the portion pack 10 from the first handling means 19 to the mounting table 20, in the embodiment, the mounting table 20 is configured to move back and forth between the receiving position S4 and the retreat position S5. However, it is also possible to adopt a configuration in which, for example, a handling means 19 consisting of a robot hand is used to remove the portion pack 10 from the transport conveyor 15 and transfer it to the mounting table 20, which is fixed in position.
(6) In the embodiment, a plurality of collection containers 11 are transferred to the tray 12 in a stacked manner. However, the collection containers 11 may be stacked flat on the tray 12.
(7) In the processing device of the embodiment, the orientation correction means 18 and handling means 19 are configured to perform orientation correction processing and pick-up processing on five rows and four columns of portion packs 10, but the number of portion packs 10 to be subjected to orientation correction processing and pick-up processing is not limited to five rows and four columns, and may be any number according to the collection shape of the collection containers 11 to be transferred to the tray 12.
(8) The first handling means 19 is provided with a row spacing change means 40 to narrow the row spacing of multiple rows and columns of portion packs 10, but various forms of row spacing change means can be adopted, such as providing the loading platform 20 with a row spacing change means that moves the row partition sections 63 closer to and away from each other.
(9) In the processing apparatus of the embodiment, the collection container 11 on the mounting table 20 is transferred to the tray 12 without changing its orientation. However, depending on the orientation of the tray 12, a configuration can be adopted in which the second handling means 23 picks up the collection container 11 from the mounting table 20, changes its orientation by 90 degrees, and then transfers it to the tray 12.
