Operation of the Embodiment Next, the operation of the intermediate partition supply device in the boxing machine according to the above-described embodiment will be described in relation to the intermediate partition supply method.

In the intermediate partition supply device 10, the pushing cylinder 41 of the pushing device 28 is urged to move the kickers 40, 40 forward from the standby position to the pushing position so that they are stored in the storage hopper 27. The lowermost partition 26 is the horizontal portion 33 of the lower guides 33, 34.
It is pushed forward along a and 34a. At this time, the pair of holding members 44, 45 in the posture changing device 29.
Are separated from each other and face the standby position, and one side portion of the partition 26 pushed out from the storage hopper 27 is inserted between the sandwiching members 44 and 45 in the open state. Further, the front end edge of the partition 26 is brought into contact with the stopper 36 for positioning.

Next, after the holding cylinder 46 of the posture changing device 29 is urged to bring the second holding member 45 close to the first holding member 44, one side of the partition 26 is held. , The rotary cylinder 47 is urged,
By rotating both holding members 44, 45 by approximately 90 degrees, the horizontal partition 26 is converted to the standing position. At this time, the holder 52 of the transfer device 30 faces the supply position, and the conversion of the partition 26 to the standing posture is not hindered. In addition, the posture conversion device 29 allows the partition 26
Is set to the upright posture, the pushing cylinder 41 is reversely biased, and the kickers 40, 40 are retracted from the pushing position to the standby position, so that the next partition 26 in the storage hopper 27 is pushed by the pushing piece 40b. , 40b to base materials 40a, 40a
Transfer to.

The reversing cylinder 55 of the transfer device 30 is urged to rotate the rotating arm 50 by about 180 degrees, and the holder 52 with the pair of grip pieces 51, 51 opened moves to the receiving position. As a result, the front end portion of the partition 26 in the upright posture enters between the gripping pieces 51, 51. At this time, since the gripping pieces 51, 51 are closed, the middle partition 26
Is held in this state until the semi-manufacturing box 14 arrives at the product box packing position of the box manufacturing apparatus 12.

In the box making device 12, the sheet hopper 1
The blank sheet 11 taken out by the sheet taking-out means 3 is placed on the bottom panel 11a between the support rails 19 and 19 facing the pair of guide members 17 and 18 in the case transfer conveyor 15. At this time, front and rear side panels 11b, 1 that are connected to the bottom panel 11a
By contacting both guide members 17 and 18 from above, 1c is bent upward as shown in FIG. 2 and is supported in an inclined state. The semi-box manufacturing case 14 is moved toward the article packing position by the running of the endless chains 16 and 16, and in the process, the first inner flap 11d connected to the front side panel 11b first faces the standby position. It is bent to the temporary bending position by the first bending means 20. Then, when the semi-manufactured box 14 arrives at the article boxing position and the case transfer conveyor 15 is stopped, the case positioning means operates to position the semi-box case 14 at the article boxing position, and The second bending means 21 is rotated from the standby position to the bending position, and the second inner flap 11e, which is continuously provided on the rear side panel 11c, is bent to the temporary bending position. As a result, the semi-box manufacturing case 14 in the article boxing position is in a semi-box manufacturing state in which the upper side and the side on the article supply side are opened.

When the semi-manufacturing case 14 arrives at the article packing position, the reversing cylinder 55 of the transfer device 30 is reversely biased, and the rotating arm 50 is rotated by about 180 degrees and is gripped by the holder 52. The intermediate partition 26 is placed in an upright posture in which the article compartment S in the semi-manufacturing case 14 is turned upside down.

Next, in the article supply device 24, the transfer end of the supply conveyors 25, 25 moves forward and backward in the article transfer direction and reaches a predetermined height at the timing when the semi-box 16 is at the article boxing position. By repeating the ascending operation, the intermediate partition 26 is removed from both conveyors 25, 25.
The articles 22 to be packaged are stacked and supplied to the article storage portions S on both sides sandwiching. Prior to the supply of the article 22 to be packaged, the intermediate partition 26 is supplied to the article storage unit S, and the holder 52 maintains the upright posture until the article 22 is supplied by a predetermined number of stages. Is held,
The positional relationship between the article to be packaged 22 and the partition 26 does not shift. Further, since the holder 52 holds the extending portion 26a of the partition 26 from the article storage portion S, the objects to be packaged 22, 2 supplied to the holder 52 and the article storage portion S are held.
2 does not interfere with each other, and the positional deviation and deformation of the articles 22, 22 are prevented. The items to be packaged 22,2
The first and second folding means 20 and 21 are supported by the first and second folding means 20 and 21 in a state in which they are folded and formed to a temporary folding position on the front side in the discharge direction of the articles 22 and 22 to be packaged in the article storage portion S. Therefore, the second inner flaps 11d and 11e are reliably supplied so that the tips in the discharge direction come into contact with each other and are positioned in the article storage section S.

The article 2 of the fourth stage is placed in the article storage section S.
When 2, 22 are supplied, the holder 52 releases the partition 26, the reversing cylinder 55 is urged to rotate the rotating arm 50 by about 180 degrees, and as described above. The holder 52 is moved so as to grasp the partition 26 in the standing posture, which is posture-converted to the receiving position. In this way, since the middle partition 26 is released at the fourth stage (the stage before the final stage), the packaged article 2 at the fifth stage (the final stage) is released.
