It is set to be performed at an appropriate timing.
[0023]
[Effect of the embodiment]
Next, the operation of the partition supply device in the boxing machine according to the above-described embodiment will be described in relation to the partition supply method.
[0024]
In the partition supply device 10, the push-out cylinder 41 of the push-out device 28 is energized, and the kickers 40 and 40 are moved forward from the standby position to the push-out position, whereby the lowermost portion stored in the storage hopper 27 is stored. The middle partition 26 is pushed forward along the horizontal portions 33a, 34a of the lower guides 33, 34. At this time, the pair of clamping members 44 and 45 in the posture changing device 29 are spaced apart from each other and face the standby position, and one side portion of the partition 26 pushed out from the storage hopper 27 is in the opened state. Between 44 and 45. Further, the front edge of the partition 26 is positioned by contacting the stopper 36.
[0025]
Next, after the clamping cylinder 46 of the posture changing device 29 is energized and the second clamping member 45 is brought close to the first clamping member 44, one side of the partition 26 is clamped, and then the rotary When the cylinder 47 is energized and the both clamping members 44 and 45 are rotated by approximately 90 degrees, the horizontal partition 26 is changed into a standing posture. At this time, the holder 52 of the transfer device 30 faces the supply position, and the conversion of the partition 26 into the standing posture is not hindered. In addition, after the partition 26 is placed in the upright posture by the posture changing device 29, the push-out cylinder 41 is reversely biased, and the kickers 40, 40 are moved back from the push-out position to the standby position, whereby the storage hopper 27 The next partition 26 is transferred from the pressing pieces 40b, 40b to the base materials 40a, 40a.
[0026]
The reversing cylinder 55 of the transfer device 30 is energized, the rotating arm 50 rotates approximately 180 degrees, and the holder 52 with the pair of gripping pieces 51, 51 opened moves to the receiving position. The front end portion of the partition 26 in the standing posture enters between the gripping pieces 51 and 51. At this time, when the gripping pieces 51 and 51 are closed, the partition 26 is gripped, and the apparatus waits in this state until the semi-box case 14 arrives at the article boxing position of the box making device 12.
[0027]
In the box making apparatus 12, the blank sheet 11 taken out from the sheet hopper 13 by the sheet take-out means is provided between the bottom rail 11 a between the support rails 19, 19 facing the pair of guide members 17, 18 in the case transfer conveyor 15. Is placed. At this time, the front and rear side panels 11b and 11c connected to the bottom panel 11a abut on both guide members 17 and 18 from above, and are bent upward and supported in an inclined state as shown in FIG. Is done. The semi-cased case 14 is transported toward the article boxing position by the travel of the endless chains 16, 16, and in the process, the first inner flap 11d connected to the front side panel 11b first faces the standby position. The first folding means 20 is bent to the temporary folding position. When the semi-boxed case 14 arrives at the article boxing position and the case transfer conveyor 15 is stopped, the case positioning means is operated to position the semi-boxed 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 connected to the rear side panel 11c is bent to the temporary bending position. As a result, the semi-box case 14 at the article boxing position is in a semi-box state where the upper side and the side on the article supply side are open.
[0028]
When the semi-made box case 14 arrives at the article boxing position, the reversing cylinder 55 of the transfer device 30 is reversely biased, and the rotating arm 50 rotates approximately 180 degrees and is held by the holder 52. The middle partition 26 is transferred to a substantially central position in the width direction on the article housing part S in the semi-box case 14 in an upright posture in which the top and bottom are inverted. In addition, this partition 26 has trouble in supply of the to-be-packaged item 22 to the goods accommodating part S in the state in which the extension part 26a extended to the side from the goods accommodating part S was hold | gripped by the holder 52. It is supported stably in a standing posture.
[0029]
Next, in the article supply device 24, at the timing when the semi-cased case 14 arrives at the article boxing position, the transfer terminal of the supply conveyors 25, 25 moves forward and backward in the article transfer direction and rises by a predetermined height. By repeating this operation, the articles 22 to be packaged are supplied in a stacked manner from the conveyors 25, 25 to the article storage portions S on both sides sandwiching the partition 26. Prior to the supply of the article to be packaged 22, the partition 26 is supplied to the article storage unit S, and the divider 26 maintains the standing posture by the holder 52 until the article to be packaged 22 is supplied a predetermined number of stages. Thus, the positional relationship between the article to be packaged 22 and the partition 26 is not shifted. Further, since the holding tool 52 holds the extending part 26a from the article storage part S of the partition 26, the holding tool 52 and the articles to be packaged 22 and 22 supplied to the article storage part S interfere with each other. There is nothing, and the positional deviation or deformation of the articles 22 and 22 is prevented. In addition, the to-be-packaged items 22 and 22 were bent and formed by the first and second bending means 20 and 21 to the temporary folding position on the front side in the discharge direction of the to-be-packaged items 22 and 22 in the article accommodating portion S. The first and second inner flaps 11d and 11e supported in the state are reliably supplied so that the tips in the discharge direction come into contact with each other and are positioned in the article accommodating portion S.
[0030]
When the fourth-stage articles 22 and 22 are supplied to the article accommodating portion S, the holder 52 releases the partition 26 and the reversing cylinder 55 is urged to rotate the rotating arm 50. Is rotated by approximately 180 degrees, and the holder 52 is moved to hold the partition 26 in the standing posture whose posture is changed to the receiving position and is in a standby state as described above. In this way, the partition 26 is released at the fourth stage (the stage before the final stage). Therefore, before the fifth stage (the final stage) of the packages 22 and 22 is supplied, the transfer device 30 The holder 52 can be moved to the receiving position of the partition 26, and the cycle time can be shortened. Moreover, since most of the height of the middle partition 26 is supported by the four-stage packages 22 and 22, even if the middle partition 26 is inclined after being released, the subsequent packages 22 are small. , 22 is not inhibited.
[0031]
When the supply of the fifth stage of the articles to be packaged 22, 22, which is the final stage of the article to be packaged, is completed, the first folding means 20 moves forward from the standby position to the folding position, whereby the first, first The inner flaps 11d and 11e are folded to the regular folding position, and the extending portion 26a of the inner partition 26 is pushed into the article accommodating portion S.
[0032]
