The second member 222 is a plate-shaped member arranged orthogonal to the left-right direction. The width of the second member 222 in the left-right direction is approximately the same as the width of the chain bag CB. It is preferable that the width of the second member 222 in the vertical direction is larger than the height of the small bag SB (in other words, the length between the adjacent connecting portions J of the chain bag CB). Since the second members 222 grip the continuous bag CB together with the adjacent second members 222 during the packing operation, they are preferably manufactured using a highly rigid material such as metal or resin.

(3-3) Control Unit The control unit 300 controls the operation of each unit of the box making apparatus 100 and the packaging subsystem 200 to realize the unfolding operation and the packaging operation. The control unit 300 controls the suction driving unit 121c, the moving unit 122b, the bottom lid forming unit 123, the conveying unit 130, the gate driving mechanism 211b, the first member driving mechanism 221a, the main frame driving mechanism 223a, and the subframe driving mechanism 223c. is connected so as to be able to transmit and receive control signals to.

The control unit 300 is, for example, a computer having a CPU and a storage device. Control unit 300 may include a plurality of computers communicatively connected. The control unit 300 controls the operation of each unit of the box making device 100 and the packaging subsystem 200 by executing a control program for the packaging device 1 stored in the storage device by the CPU. Note that the control unit 300 may not be realized by software, may be realized by hardware, or may be realized by cooperation of software and hardware.

(4) Details of Operation of Cartoning Apparatus (4-1) Unfolding Operation The unfolding operation will be described. 8A to 8D are plan views of the box manufacturing section 120 at each stage of the unfolding operation. The deployment motion includes a preparatory motion, a first motion, a second motion, and a third motion.

(4-1-1) Preparatory Operation First, the control section 300 causes the moving mechanism 122 to perform a preparatory operation. In the preparation operation, the moving mechanism 122 moves forward the holding portion 121 holding the first side surface T1 of the cardboard sheet S positioned most forward among the plurality of cardboard sheets S accommodated in the accommodation portion 110 . Specifically, the control unit 300 causes the suction cup 121a of the holding unit 121 that has moved to the first position P1 to adhere to the first side surface T1 of the cardboard sheet S by controlling the suction driving unit 121c. Thereafter, the control unit 300 causes the moving unit 122b to move the holding unit 121 holding the cardboard sheet S forward by a predetermined distance D0 (see FIG. 8A). The distance D0 is, for example, approximately 300 mm.

(4-1-2) First Operation Next, the control section 300 causes the moving mechanism 122 to perform the first operation. In the first operation, the moving mechanism 122 moves the holding portion 121 holding the cardboard sheet S in a direction toward the first position P1. Specifically, the control unit 300 causes the moving unit 122b to move the holding unit 121 toward the first position P1 (backward) by a predetermined distance D1 (see FIG. 8B). Distance D1 is shorter than distance D0. The distance D1 is, for example, approximately 100 mm.

As a result, the first side surface T1 of the cardboard sheet S moves rearward by a distance D1. As the first side surface T1 moves, the second side surface T2, the third side surface T3, and the fourth side surface T4 also move rearward. At this time, the first side surface T1 is in contact with the second side surface T2 and the third side surface T3 facing the first side surface T1.

(4-1-3) Second Action Next, the control section 300 causes the moving mechanism 122 to perform the second action immediately after performing the first action. In the second operation, the moving mechanism 122 moves the holding portion 121 holding the cardboard sheet S in a direction to approach the second position P2. Specifically, the control unit 300 causes the moving unit 122b to move the holding unit 121 toward the second position P2 (forward) by a predetermined distance D2 (see FIG. 8C). In this embodiment, the distance D2 is the same distance as the distance D1.

As a result, the first side surface T1 of the cardboard sheet S moves forward by a distance D2. At this time, the second side surface T2, the third side surface T3, and the fourth side surface T4, which are not held by the holding portion 121, follow the movement of the holding portion 121 due to the inertial force generated in the first operation. It moves slightly toward the direction (rearward) approaching the first position P1. As a result, the side portion T is slightly expanded to form a gap GS between the second side T2 and the third side T3 and the first side T1 and the fourth side T4 (see FIG. 8C).

(4-1-4) End Operation Finally, the control unit 300 causes the moving mechanism 122 to perform the end operation. In the ending operation, the moving mechanism 122 moves the holding portion 121 holding the cardboard sheet S to the second position P2. Specifically, the control unit 300 causes the moving unit 122b to move to the second position P2 (see FIG. 8D).

As a result, the first side surface T1 of the cardboard sheet S moves to the second position P2. As described above, in the second operation, since the gap GS is generated between the second side surface T2 and the third side surface T3 and the first side surface T1 and the fourth side surface T4, air enters the gap S1. there is Therefore, even if the first side surface T1 moves to the second position P2 by the second operation, the second side surface T2, the third side surface T3, and the fourth side surface T4 are restricted from following the movement of the holding portion 121. . As a result, the folded side portion T of the cardboard sheet S is further unfolded into a square tube shape. This completes a series of deployment operations.

In the above description, the second operation and the ending operation are described as separate operations for the sake of convenience. you can go

When the unfolding operation is completed, the control section 300 controls the bottom cover forming section 123 to form the cardboard box B. As shown in FIG. Specifically, the control unit 300 causes the bottom cover forming unit 123 to close the bottom cover side flap F2 of the corrugated cardboard sheet S that has been expanded into a rectangular tubular shape to form the bottom cover BC.

After that, the control unit 300 causes the transport unit 130 to transport the cardboard box B with the bottom lid BC to below the opening 211 formed in the mounting table 210 of the packaging subsystem 200 . In this embodiment, the transport unit 130 rotates the cardboard box B by 90° in a plan view so as to match the orientation of the packaging subsystem 200 (see FIG. 1).

In the above description, the present invention relates to the box manufacturing apparatus 100 including the moving mechanism 122 that performs the unfolding operation. You can capture the deployment motion. That is, a first action of moving one side of the cardboard sheet S in a first direction (direction approaching the first position P1), and a second action of moving one side of the cardboard sheet S in a second direction opposite to the first direction The invention relates to a box-making method in which the second operation of moving toward the second position P2 is performed a predetermined number of times, and the box-making apparatus 100 may be regarded as executing this box-making method.

(4-2) Packing operation The packing operation will be described. 9A-9G are side views of the cartoning subsystem 200 at various stages of the cartoning operation.

Before the packing operation is started, the chain bags CB are placed in the center of the placing table 210 in the left-right direction in such a manner that the small bags SB extend linearly in the front-rear direction. Although the method for placing the continuous bag CB is not particularly limited, for example, the continuous bag CB placed on the end of the mounting table 210 in the left-right direction is placed using a rod-shaped guide member (not shown) extending in the front-rear direction. to the center in the horizontal direction.

First, the control unit 300 controls the first member driving mechanism 221a, the main frame driving mechanism 223a, and the sub-frame driving mechanism 223c to move the first member 221, the main frame 223, and the sub-frame 223b to predetermined initial positions. As it moves, it closes the gate 211a. Specifically, the controller 300 moves the first member 221 and the main frame 223 upward so that the first member 221 and the second member 222 do not contact the continuous bag CB. Further, the control unit 300 moves each of the plurality of sub-frames 223b so that the lower end of the supporting first member 221 is positioned directly above the predetermined connecting portion J (see FIG. 9A). More specifically, the control unit 300 moves the sub-frame 223b1 so that the first member 221 is positioned directly above the connecting portion J that connects the first and second pouches SB from the front. Further, the control unit 300 moves the sub-frame 223b2 so that the supporting first member 221 is positioned directly above the connecting portion J that connects the third pouch SB and the fourth pouch SB from the front. Further, the control unit 300 moves the sub-frame 223b3 so that the supporting first member 221 is positioned directly above the connecting portion J that connects the fifth and sixth pouches SB from the front. Further, the control unit 300 moves the sub-frame 223b4 so that the supporting first member 221 is positioned directly above the connecting portion J that connects the seventh pouch SB and the eighth pouch SB from the front. Further, the control unit 300 moves the sub-frame 223b2 so that the supporting first member 221 is positioned directly above the connecting portion J that connects the ninth and tenth pouches SB from the front.

Next, the control unit 300 controls the first member driving mechanism 221a to move the first member 221 downward so that the continuous bag CB assumes a predetermined posture. Specifically, the control unit 300 moves the first member 221 downward until the continuous bag CB is slightly bent downward at the connection portion J with which the first member 221 contacts when viewed from the side. As a result, the connection portion J that is not in contact with the first member 221 is slightly bent upward (see FIG. 9B). At this stage, the second member 222 does not come into contact with the chain bag CB.

Next, the control unit 300 controls the sub-frame driving mechanism 223c while pushing the connecting portion J downward with the first member 221 so that the distance between the adjacent sub-frames 223b is shortened at the same speed. The sub-frames 223b other than the frame 223b1 (specifically, sub-frame 223b2, sub-frame 223b3, sub-frame 223b4, and sub-frame 223b5) are moved forward. As a result, the connecting portions J of the continuous bag CB that are in contact with the first member 221 approach each other, and the continuous bag CB is arranged such that the outer surfaces of the adjacent small bags SB contact each other via the connecting portion J when viewed from the side. is folded like an accordion (see FIG. 9C).

Next, the controller 300 controls the main frame drive mechanism 223a to move the main frame 223 downward. Specifically, the control unit 300 inserts the second member 222 between the outer surfaces of the adjacent pouches SB that are in contact with each other and face upward when placed on the mounting table 210. so as to move the second member 222 downward. After that, the controller 300 controls the first member driving mechanism 221a to move the first member 221 upward.

Furthermore, the control unit 300 controls the subframe drive mechanism 223c to move the subframes 223b other than the subframe 223b1 forward so that the distance between the adjacent subframes 223b is further reduced. Specifically, the control unit 300 reduces the distance between the adjacent sub-frames 223b to a position where the adjacent second members 222 can grip the pouch SB. Thereby, the second members 222 can hold the chain bag CB together with the adjacent second members 222 without dropping (see FIG. 9D).

Next, the controller 300 controls the gate driving mechanism 211b to open the closed gate 211a. After that, the control section 300 controls the main frame driving mechanism 223 a to move the second member 222 below the mounting table 210 through the opening 211 . As described above, since the cardboard box B is transported below the opening 211, the chain bag CB enters the cardboard box B as the second member 222 moves downward on the mounting table 210 ( See Figure 9E).

Next, the control unit 300 controls the sub-frame drive mechanism 223c to move the sub-frames 223b other than the sub-frame 223b1 rearward so that the distance between the adjacent sub-frames 223b increases. Specifically, the control unit 300 increases the distance between the adjacent sub-frames 223b to a position where the adjacent second members 222 cannot grip the pouch SB. As a result, the second members 222 cannot grip the continuous bag CB together with the adjacent second members 222 .

Furthermore, the control unit 300 controls the first member driving mechanism 221a to move the first member 221 downward so as to contact the upper surface of the continuous bag CB. At the same time, the controller 300 controls the main frame driving mechanism 223a to move the main frame 223 upward until the second member 222 stops contacting the continuous bag CB. As a result, the second member 222 is pulled out from between the contacting outer surfaces of the adjacent small bags SB, and the chain bag CB falls toward the bottom lid BC of the cardboard box B (see FIG. 9F).

Finally, the control section 300 controls the first member driving mechanism 221a, the main frame driving mechanism 223a, and the sub-frame driving mechanism 223c to return the first member 221, the main frame 223, and the sub-frame 223b to their initial positions. , closes the opened gate 211a (see FIG. 9G).

Although not shown, the cardboard box B in which the continuous bags CB are packed is then carried out of the packing machine 1 . This completes the series of packing operations.

It should be noted that the mode of the packing operation described here is merely an example, and can be changed as appropriate.

In the packaging device 1 according to Modification A, the moving mechanism 122 repeats the first action and the second action multiple times. The number of times of the first action and the second action can be, for example, about 2 to 5 times. At this time, the distance D1 and the distance D2 are the same. In other words, in the packaging device 1 according to Modification A, the moving mechanism 122 performs the first action and the second action multiple times at the same position.

According to the packaging device 1 according to Modification A, since the first operation and the second operation are performed multiple times, the corrugated cardboard sheets S can be more reliably expanded into a square tube shape.

(6-2) Modification B
In the packaging device 1 according to Modification A, the moving mechanism 122 performs the first action and the second action multiple times at the same position, but these may be performed at different positions. 10A and 10B are plan views of a box manufacturing device 100 for explaining the unfolding operation performed by the cartoning device 1 according to Modification B. FIG.

In modification B, the moving mechanism 122 starts the first motion twice from different positions. Specifically, in Modification B, the distance D2 is set to a distance D2a longer than the distance D1 (see FIGS. 10B and 10D). As a result, in the cartoning apparatus 1 according to Modification B, the position where the second first action (see FIG. 10C) is started is the second position compared to the first first action (see FIG. 10A). Closer to position P2. In other words, in the packaging device 1 according to Modification B, the position at which the first action is started changes forward as the first action and the second action are repeated. In addition, the number of times of the first operation and the second operation is not limited to two, and may be three or more.

According to the packaging device 1 according to Modification B, the position where the first action is started approaches the second position P2 as the first action and the second action are repeated in the unfolding action. The corrugated cardboard sheet S can be expanded into a rectangular tube shape in a short time.

(6-3) Modification C

FIG. 11B is a side view of the box making section 120 included in the box packing apparatus 1 according to Modification C. FIG.

The first unfolding assisting part 124 contacts the upper lid side flap F1 during the second operation to restrict the movement of a part of the cardboard sheet S toward the second position, thereby unfolding the cardboard sheet S. It is a supporting member. Specifically, the first deployment assisting portion 124 is a bar-shaped member that extends downward from above the region where the cardboard sheets S move in the box making portion 120 . The length of the first deployment assisting portion 124 is set to a length that does not contact the side portion T of the corrugated cardboard sheet S moving forward during the first operation, but contacts only the upper lid side flap F1. Further, the first unfolding assisting portion 124 is provided at a position where it passes through the gap G1 between the flaps F11 and F14 of the cardboard sheet S immediately after moving from the first position P1 and comes into contact with the flap F13. Further, the first deployment assisting portion 124 is formed so that the tip becomes thinner toward the tip (downward in this embodiment).

As a result, after the cardboard sheet S is moved from the first position P1, the first deployment assisting portion 124 contacts the flap F13 through the gap G1. The forward movement of the flap F13 in contact with the first deployment assisting portion 124 and the third side surface T3 connected to the flap F13 is restricted by the first deployment assisting portion 124 .

As a result, the forward movement of the third side surface T3 is restricted when the holding portion 121 moves forward (the first motion and the ending motion). As a result, the folded side surface portion T of the corrugated cardboard sheet S is reliably unfolded into a rectangular tubular shape.

When the transport unit 130 transports the cardboard box B on which the bottom cover BC is formed, the flap F13 is bent rearward with respect to the third side surface T3. is suppressed.

According to the boxing device 1 according to Modification C, the expansion of the cardboard sheet S is assisted by the first expansion assisting part 124, so that the cardboard sheet S can be expanded more reliably into a square tube shape.

The packaging device 1 according to Modification C may include an actuator (not shown) that moves the first deployment assisting portion 124 to a position where it does not come into contact with the upper lid side flap F1. The actuator is controlled by the control section 300, and moves the first deployment assisting section 124 to a position where it does not come into contact with the upper lid side flap F1 when the first operation ends. As a result, the first deployment assisting portion 124 can move to a position where it does not come into contact with the upper lid side flap F1 after the end of the first operation.

According to the boxing device 1 according to Modification D, the first expansion assisting portion 124 is prevented from interfering with the transportation of the cardboard box B. FIG.
