[Explanation of action]

 Next, the operation of the automatic continuous packaging device for the pillow package including the device of the present invention will be described based on the above embodiment. A pillow packaged product 1 wrapped by a pillow packaging machine (not shown) is carried in the direction of the arrow by a belt conveyor 2 as shown in FIG. The pillow package 1 is stopped on the belt conveyor 2 by a stopper 7 provided at the downstream end of the belt conveyor 2. The cylinder 9 is activated by this stop signal, and the pusher plate 9a of the cylinder 9 sets the pillow package 1 on the belt conveyor 2 to the shaping portion a where the pillow package 1 is set on the receiving plate 8. Return to position.

The cylinder 10 is actuated by a signal that the pillow package 1 is set on the shaping part a of the receiving plate 8, and the pressing plate 11 of the cylinder 10 is lowered to restrain the pillow package 1 on the receiving plate 8. .. Simultaneously with this restraint action, the solenoid 19 works, and the shaper 21 pushes the two ears 1a of the pillow package 1 upward from the diagonally downward direction through the through-hole 18, and the two ears 1a are incomplete. Attach a downward fold. The shaper 21 returns to the old position by the action of the solenoid 19. When the solenoid 19 receives the signal returned to the old state, the cylinder 9 is actuated again, and the following pillow package 1, which is on standby and stopped on the belt conveyor 2, is transferred to the shaping part a of the receiving plate 8 and set. To do. By this action, the preceding pillow package 1 that was in the shaping part a with the folds attached to the ears 1a is pushed outward by the intervention of the subsequent pillow package 1, and is provided on the receiving plate 8. It reaches on the opening 28.

When the sensor 46 detects that the pillow package 1 has been set on the opening 28, the cylinder 29 in the vertical posture operates, and the pusher plate 29 a provided at the upper end of the cylinder 29 serves to fix the pillow package 1 to both shaping plates. While sandwiching between 31, raise to a predetermined height. At this time, the folds of the incompletely preformed ear 1a are made completely folds by the sandwiching action of the two shaping plates 31. Then, the pusher plate 29a returns to the old state by the action of the cylinder 29. The cylinder mechanism 34 is actuated in response to the old state return signal of the cylinder 29 to rotate the rotary shaft 32 by about 180 °, and the arm 33 of the rotary shaft 32 in the direction shown by the arrow in FIG. Then, the pillow package 1 which is sandwiched and supported between the two shaping plates 31 is inverted by 90 ° and transferred onto the guide plate 36. At this time, the folds formed on the ears 1a of the pillow package 1 are turned sideways. Then, the cylinder 37 operates in response to the signal that the cylinder mechanism 34 has returned, the pillow package 1 on the guide plate 36 is pulled toward the cylinder 37 by the plate 37b, and the pillow package 1 is provided on the upstream side of the upper belt conveyor 35. Reprinted above. Then, the cylinder 37 returns to the old state.

As shown in FIG. 2, the pillow package 1 transferred laterally on the upstream side of the belt conveyor 35 is conveyed to the downstream side of the belt conveyor 35 and stopped by the stopper 38. It is detected by the sensor 39. The cylinder 43 is actuated by the detection signal of the sensor 39, and the pillow package 1 is inserted and supported by the pusher plate 43b of the sensor 39 to the deepest part of the stacker 40. When the cylinder 43 returns to the old shape, the subsequent pillow package 1 reaches the position of the stopper 38, and the cylinder 43 is activated again by the signal of the sensor 39, so that the pillow package 1 is operated in the same manner as above. The sheets are fed into the stacker 40 and arranged side by side in close contact with the pillow package 1 which is inserted and supported previously. The stroke of the cylinder 43 for feeding the second pillow package 1 to the stacker 40 is designed to be smaller than the stroke of the first stroke by the thickness of the pillow package 1.

The two pillow packages 1 are sandwiched and supported in the stacker 40, and the cylinder 42 operates in response to the signal that the cylinder 43 has been restored. Then, the pusher plate 42a of the cylinder 42 pushes down the two pillow packages 1 in the stacker 40, and the cubic one-touch assembly box 4 stands by on the receiving plate 44 provided directly below the stacker 40. Box inside. At this time, the flap 4a and the cover plate 4b of the box 4 are in a vertical state. The means for shaping the one-touch assembly box 4 in a flat posture into a cubic shape will be described later.

After the two pillow packages 1 are packed in the box 4 by the action of the cylinder 42, the cylinder 47 shown in FIG. 2 is activated by the signal that the cylinder 42 returns to the old position. Then, the pusher plate 47b of the cylinder 47 transfers the box 4 onto the upper side of the belt conveyor 5 as shown in FIG. 4, and the pillow package 1 is provided with a belt as shown by phantom lines in FIG. It is stopped at the position of a stopper 76 provided on the downstream side of the conveyor 5. In this stopped state, the function book 75 in the magazine case 77 is supplied into the box 4 by suction means (not shown) or the like. Next, the cylinder 78 operates in response to the supply completion signal of the function book 75, and the pusher plate 79 supplies and sets the box 4 between the frame plates 81a and 81b provided on the pedestal 80. The pusher plate 79 returns to the old position by the action of 78.

When the sensor 87 detects that the box 4 has been supplied and inserted between the frame plates 81a and 81b, the cylinder 89 is activated by this detection signal, and the holding piece 90 provided at the tip of the rod 89a is effective. The inner flap 4a on the side is folded as shown in FIG. By this signal, a conveying means (not shown) such as a chain is activated, and the pedestal 80 starts moving in the direction of the arrow along the traveling path 6. When the pedestal 80 starts to move, the guide portion 91a provided at the upstream end of the base plate 91 arranged on one side of the traveling path 6 causes the inner flap 4a on the downstream side of the box 4 to move to the lower side as shown in FIG. It will be folded. When the inner flap 4a is folded, the cylinder 83 is actuated, the folding plate 85 is tilted inward through the pivot shaft 84, and the lid plate 4b is folded as shown in FIG. .. At this time, as shown in FIG. 13, the cylinder 89 has returned to the old position. In this state, the cradle 80 is conveyed along the traveling path 6 in the direction of the arrow.

After the pedestal 80 starts moving, the lid plate 4b is folded by the folding plate 85, so that the tip of the lid plate 4b is provided on the base plate 91 as shown in FIG. It moves while being mounted on the guide frame 92. As shown in FIG. 14, the insertion tongue piece 4c connected to the tip of the cover plate 4b via a fold has an obtuse fold as shown in the figure by the action of the tapered surface 94a of the first roller 94. Granted at the fold. Next, as shown in FIG. 15, the folds are given a more nearly right-angled fold by the vertical surface 96a of the second roller 96, and further as shown in FIG. 16 by the conical surface 97a of the third roller 96. A sharp angled fold is given to the fold. Further, as shown in FIG. 17, the flat conical surface 98a of the fourth roller 98 provides a sharp double fold in the fold. However, since the restoring force acts on the high-quality paper material forming the box 4, even if folding is applied as shown in FIG. 17, the insertion tongue piece 4c is restored to an obtuse angle when left as it is. 18, the insertion tongue 4c that has passed through the fourth roller 98 is immediately folded, and the restoring force is suppressed by the vertical surface 99a of the holding plate 99, and the insertion tongue 4c is held in the vertical posture. .. Then, the tongue piece 4c is inserted into the box 4 by the circumferential surface 101a of the fifth roller 101, and the covering of the box 4 is completed.

As described above, the pedestal 80 on which the box 4 on which the cover plate 4b has been covered is mounted, reaches a predetermined position on the downstream side of the traveling path 6 and stops, as shown by a phantom line in FIG. .. The cylinder 103 is actuated by this stop signal, and the box 4 is sent to the label sticking machine H through the opening 102 formed between the frame plates 81a and 81b, and the label sticking machine H inserts the lid plate 4b. A label (not shown) is affixed to the side plate 4d on the side of the retracting tongue 4c in a bridge-like manner to fix the cover application posture. The box 4 on which the label has been attached is sent in the direction of the arrow in FIG. 10 and all the box packaging work is completed.

Next, the operation of the automatic assembly apparatus D for the one-touch assembly box 4 will be described with reference to FIGS. 4 to 9. For example, the cylinder 51 operates in synchronization with the operation signal of the cylinder 43 for feeding the pillow package 1 to the stacker 40, and as shown by the phantom line in FIG. The front side plate 4g of the one-touch assembly box 4 at the tip end is pressed and the suction cup 54 is attracted to the side plate 4g of the one-touch assembly box 4 by the vacuum suction activated by the box detection signal of the sensor 56, and then the cylinder 51 is returned to the old position. .. The initial state in which the cylinder 51 returns to the old state is shown in FIG. Due to the pulling action of the cylinder 51, the outer side surface of the lower side plate 4e forming the box 4 comes into contact with the large diameter shaping roller 58 to press the side plate 4e upward, and then the shaping roller 58 is pressed. As shown in FIGS. 6 and 7, the side plate 4e is further pushed in the upward direction by the small-diameter shaping roller 60 disposed on the higher side, and gradually shaped into a cubic shape.

The small-diameter shaping roller 60 is constantly pressed by the elastic force of the spiral spring 62 against the outer side surface of the side plate 4e, and the outer surface of the side plate 4f on the upper side of the box 4 which is cubical while being pushed in the upper direction is While being pressed against the front surface of the pusher plate 66 of the cylinder 65, the cylinder 51 pulls it outward. Then, as shown in FIG. 8, the outer side surface of the side plate constituting the box 4, that is, the side plate 4g to which the suction cup 54 is sucked is aligned with the plate surface of the regulation guide plate 73. At this time, the shaping roller 60 having the small diameter is disengaged from the side plate 4e and returned to the old shape by the action of the spiral rib 62.

The cylinder 63 is actuated by a signal that the shaping roller 60 having a small diameter is restored, and the L-shaped restraining piece 64 attached to the tip of the shaping roller 60 causes the corner portion where the side plates 4d and 4e intersect to each other. As shown in FIG. 8, the one-touch assembly box 4 is pressed from the outside to form the completed cubic box 4. Then, when the pressing piece 64 returns to its original position due to the action of the cylinder 63, the cylinder 65 operates, and the box 4 is supplied onto the receiving plate 44 provided directly below the stacker 40, as shown in FIG. The cylinder 48 is actuated by the supply signal of the box 4 and presses the L-shaped restraining piece 49 against the corner portion where the side plates 4f and 4g intersect, thereby stabilizing and maintaining the shape of the box 4 when the pillow package 1 is packed. After packing, the cylinder 48 returns to the old position.
