If the relationship between the mountain fold and the valley fold is reversed to obtain a symmetrical packaging cushion with the receiving part facing, the position of the plank supporting part should be the distance between the fold curves, and either the left or right. If it is set shifted, the fold fold portion and the mountain fold portion are reversed, and a symmetrical packaging cushion in which the receiving portions face each other easily can be obtained with the same device. It should be noted that a symmetrical cushioning body for packaging can be obtained by simply feeding the blank in a zigzag bending means in a reversed state without using the above method.

- the pusher conveyor 101 has a plurality of narrow belts having pushers 102 arranged at parallel intervals, and the zigzag fold of the plank 10 is synchronized with the progress of the bending by the support motor 103. Send to location.
- the blank 10 supplied from the blank stacker to the pusher conveyor 101 by the blank feeder 105 is pushed by the pusher and hits the stopper 104 located at the downstream end.
- the zigzag fold is started.
- the valley-folding plate drive mechanism 107 has a comb-tooth-shaped mountain-folding fold formed so that it can move up and down through the narrow belts of the pusher conveyor. It has a curved plate 109, and has a mechanism for vertically moving the folded plate for mountain folding and moving it left and right in the conveyor traveling direction. As shown in Fig. 14, the comb-shaped mountain-folded folding plate 109 is slightly inclined in the blank feed direction, so that it collides well with the folding curve at the mountain-folding position. It is becoming easier.
- the comb-shaped mountain-folded bending plate 1 09 has a collar member 1 1 2 screwed to a vertically driving screw rod 1 1 1 provided upright on the fixed frame 110.
- the movable frame 113 is provided so as to be slidable.
- the movable frame 1 13 moves up and down by the screw action when the motor 1 1 4 rotates the screw rod 1 1 1.
- Reference numeral 115 denotes a guide port for vertically moving the movable frame provided on the fixed frame.
- the fixed frame 110 has a pair of first rails 116 that enable the folding plate 109 for mountain folding to move in the direction of travel of the conveyor, and a guide 1 17 that fits into the rail.
- the plate 1 18 to which is fixed is slidably supported.
- a pair of rods 119 fixed to the base of the bent plate for mountain folding is fitted to a pair of collars 120 provided on the plate 118 so as to be vertically movable.
- a collar 123 screwed to a screw rod driven by a motor that drives the folding plate 109 for mountain folding in the traveling direction of the conveyor is fixed to the plate 118. Therefore, the plate 1 18 moves along the first rail 1 16 via the collar 123 by rotating the screw rod 1 2 4.
- the plate 1 19 moves, it is transmitted by the rod 1 19 to the folding plate 1 09 for mountain folding, and the second guide 1 2 2 moves on the second rail 1 2 1 and is used for mountain folding.
- the folding plate 109 can be moved in the blank feed direction.
- the motor 114 is driven, the movable frame 113 moves up and down via the screw rod 111. Therefore, the folding plate 109 for mountain folding can perform a combined movement of vertical movement and movement in the plank conveyance direction.
- the valley folding plate 1 25 has a comb-like shape that is inclined downward in the blank transport direction, as shown in FIG. It is bent like a hook.
- the bent plate for valley folding 125 is provided so as to be able to move in parallel along the upper part of the pusher conveyor, and its base is screwed to a screw rod 127 driven by a motor 126. It is fixed to the collar member 1 2 8 Its tip engages a fold curve that forms a valley fold so that it can move with the blank.
- the holding mechanism 108 presses the one formed in the mountain-fold shape by the both folding plates further in the stopper direction so as to catch the bending so as to be sure and to maintain the bending state.
- the presser plate 130 moves up and down and left and right.
- 13 1 is a motor for moving in the horizontal direction
- 13 2 is a motor for moving in the vertical direction.
- the blank 10 is pushed by the pusher 102 and fed until it hits the stopper 104 provided at the tip.
- the folded plate 109 for mountain folding, the folded plate 125 for valley folding, and the presser plate 130 are located at the home positions where they do not engage with the blanks.
- the tip end thereof hits the folding curve of the first mountain folding, and further rises and moves forward in that state.
- the tip of the valley fold plate is moving above the valley fold curve, and when the blank is lifted by the rise of the mountain fold plate 109, the valley fold curve is obtained. Hits the valley-folding plate, preventing further rise (b).
- the valley-folding plate also moves forward in cooperation with the movement of the mountain-folding bending plate in the forward direction, so that the valley fold line is pressed and the mountain fold is performed well.
- the fold plate 109 for mountain fold descends and returns to the initial position.
- the presser plate 130 descends from the vertex of the mountain fold to a position slightly lowered and engages with this portion, thereby preventing the fold from returning as the mountain fold plate descends.
- the presser plate 130 and the folded plate for valley folding 125 move further in this state, and the thickness between the valley folds becomes ⁇ . Make sure that the fold is strong.
- the presser plate 130 keeps holding the left end of the bent portion in the drawing, and during that time, the mountain-folded bent plate 109 returns to the position where it engages with the next curved line of the mountain-folded portion.
- the valley fold plate 1 25 returns from the right side to a position where it engages with the three-fold valley fold curve ((d) in the same figure).
- the second mountain folding is performed, and the mountain folding bent plate and the valley folding bending plate return to the state shown in (c).
- zigzag folding can be sequentially performed by repeating the states (d) to (e).
- the pusher of the conveyor is always pressing the blank, and the pusher conveyor always moves with the folding plate for mountain folding, the folding plate for valley folding 109 and the presser plate 130. They move in time.
- the encoder measures the rotation angle of the servo motor 103 that drives the pusher conveyor, controls the pusher conveyor, and based on the control amount, the folding plate drive mechanism for mountain folding 106, The valley folding plate drive mechanism 107 and the presser mechanism 108 are integrally controlled.
- the movements of the pusher conveyor 101, the bent plate for mountain folding 109, the bent plate for valley folding 125, and the presser plate 130 are based on the movement of the pusher conveyor 101. If all programs are programmed in advance and stored in the control device, zigzag bending can be automatically performed at high speed just by specifying the program. In addition, when bending blanks of different sizes in a zigzag manner, it can be performed simply by instructing all the moving distances etc. by a program, so that it is possible to respond quickly without the need for special type change work. .
- the sheet is extruded in a direction perpendicular to the paper of FIG. 14, and the process proceeds to the next laminating step.
- gluing nozzles as shown in FIG. 11 are arranged on both sides of the blank before the zigzag bending apparatus, and before the bending step, The gluing process has been completed.
- the gluing may be performed after the zig-sag bending step as in the embodiment.
- the present invention is not limited to the above-described embodiment, and is within the technical scope thereof.
- the shape of the article receiving portion is not limited to the above-mentioned shape, and can be formed into an arbitrary shape corresponding to the article to be supported.
- the terms “for mountain fold” and “for valley fold” described in the specification are It is relative and does not necessarily limit what is located on the lower side or what is located on the upper side.
- the packaging cushion according to the present invention and the method and apparatus for manufacturing the same are used as packaging cushions for providing goods that are easily damaged by external impacts, such as precision equipment, to physical distribution. It is useful as a manufacturing method and a manufacturing device that automatically manufactures it. Especially, it is possible to assemble a completely recyclable packaging buffer simply by folding one piece of corrugated cardboard. As a result, it is possible to achieve significant labor savings and cost reductions, and industrial applicability is high.
