Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be applied to a method of stacking a certain number of articles, such as paper cups or brimmed hats each having an inverted conical shape and a flange-like protrusion at the end of the eye, in a fitted state. The present invention relates to a stacking device in a boxing device that stacks stacked products in multiple rows and stages and packs them into boxes.

In order to reduce the stacking volume of such inverted cone-shaped articles with ridges and to prevent loads from collapsing between stacked articles, the ridges of the items that are adjacent to each other on the left, right, upper and lower sides are shifted from each other, and the objects are intertwined with each other. The shortest distance (iJ) must be brought into contact with each other, and they must be stacked three-dimensionally and then packaged. However, this work is complicated, so conventionally the only option was to do it manually, which was both inefficient and expensive. .

The present invention has been made in view of the above circumstances, and the above-mentioned articles with projecting edges are inserted into adjacent packaging boxes in a state in which the projecting edges are staggered and intertwined.

An embodiment of the present invention will be described in detail below with reference to the drawings.

For example, inverted conical paper cups 1 and 1 as shown in Figures 1 and 3.

Six similar glue lids 67 are placed on the upper side of this table 62,
67... are provided, and these glue lids 67, 67.
. . ., six rods 68 are placed between the five trays 31, 31, . . . in the packaging position 55.
, 68... are extended rearward.

As shown in Figures 5 and 6, a cylinder 80 is provided at the center of the support frame 61, 61, etc. to send the lifters 67, 67 upward one by one. 5, 6 As shown in the figures, a plate 86 is fixed to the upper end of the piston 81 of this cylinder 80, on which claws 82, 83 that engage with the inner surface of the lid 67 are pivoted by shafts 84, 85. ，

A cylinder 88 is provided on the plate 86, which operates in a position that does not engage the pawls 82,83.

At the top of the support frames 61, 61 and above the boxing position 55, there are claws 69, 69 that lock the bottom surfaces of both sides of these lids 67.
A slope yi, 71 is formed on the lower side of this pawl 69, 69 to engage with the flap 67.

Cylinder 72°7 provided on both sides of the upper part of support frame 6L 61
The piston claw 2 presses the outer upper surface of the claws 69, 69 73.
．． Fix 73.

. The above-mentioned rods 68, 68, . . . are attached to the upper rear surface of the support frame 61.
A comb-shaped button 74 extending between ... is provided to operate rearward, and behind it, as shown in Figure 7, a receiving frame 76 supporting a packaging box 75 with an open front is rotated by a shaft 77. Provide as much as possible.

Next, the operation of this device will be explained.

As shown in the first diagram, the bar-shaped piles 2, 2... are sent forward intermittently at regular intervals by the attachments 3, 3... of the conveyor 4, and are stopped at their front ends. .

Next, the piston 7 of the cylinder 6 of the lifter device 5 moves upward in FIG. 2, and the horizontal table 8 and the rocking table 9 rise.
The rods 21 and 22 support both sides of the lower part of the bar-shaped stacked body 2 on the conveyor 4 and raise it.

In this process, the upper end 16 of the pawl 14 engages with the cam 18, the pawl 14 is removed from the rocking table 9, the rocking table 9 is tilted to the right, and the bar-shaped stacked bodies 2 on the bars 21 and 22 are falls onto the slide 25, rolls downward, and is stopped by the separator 26.

When the bar-shaped stacks 2, 2, . 17 engages with the upper end 15 of the claw 13,
The claw 13 comes off the rocking table 9, the rocking table 9 tilts to the left, and the bar-shaped piles on the rods 21 and 22 fall onto the slide 23 and are stored.

When the tray 31 held by the U-shaped rails 44 and 45 of the chains 46 and 47 rises to the position 43 as shown in FIG. The bar-shaped stacked bodies 2 in the separator 26 are pushed to the right in FIG. is maintained.

Next, the shutter 51 is raised, and the base 33 of the tray 31 is pushed to the right one pitch at a time in FIGS. 1 and 2A by the cylinder 50, and is inserted into the slide guides 52 and 53.

A new tray 31 is then raised to position 43 and fed into the slide guides 52, 53 with the bar stacks 2 in exactly the same way.

At this time, the push plate 36 or 36a of each tray 31 engages with the cam 39 and presses the bar-shaped stack 2 on the tray 31 to the right at the opening in FIG. The tray is designated as tray B.

As shown in FIG. 3, the edges 1a of the bar-shaped stacks 2 on the trays A and B are alternately shifted by half a pitch, so they do not coincide with each other, and therefore each bar-shaped stack 2 ,2...
... are kept close to each other at the shortest distance.

Thus, a group of five trays 3L3 as shown in FIG.
1... is sent out, the piston of the cylinder 56 moves greatly to the right, and these group of trays 31, 3
1...and the bar-shaped stacked body 2゜2...
... are sent to the packaging position 55.

Next, as shown in FIG. 6, the piston 81 of the cylinder 80 rises, and its pawls 82, 83 lift the first lid 67, and the rods 68, 68, . . .
. . . Holds the upper bar-shaped stacked bodies 2, 2 .
1 and flips up the pawl 69.69, and comes to the upper side and is placed on the pawl 69.69.

Next, the piston 81 of the cylinder 80 descends and returns to its original position, while the chains 66, 66 cause the table 62 to rise by one lifter 67, and the next lifter 67
6. Claws 82 and 83 attached to the tip of the illustrated piston 81
raise it to the position where it engages.

The five empty trays 31, 31, . , when the trace stoppers 59a shown in FIG. 2C are raised, they are returned one by one to the lower part of the chain 46, 47, and the one tray 31a and the wheels 35 are placed on the U-shaped rail as shown in FIG. 44 and 45.

Next, the second group of trays 31, 31, . 31°31
. . . is placed on the claws 69 and 69 while holding the upper bar-shaped stacked bodies 2, 2 .

Since the number of trays 31, 31, .

For example, when the first group of trays is ABABA, the second group of trays is BABAB, and the third group of trays is ABABA.
becomes.

Therefore, each group of bar-shaped stacked bodies 2, 2... stacked on the claws 69, 69, and those adjacent above and below are shifted by half a pitch from each other, and each bar-shaped stacked body 2, 2...
. . . are aggregates that are adjacent to each other in the left and right upper U rows at the shortest distance.

Thus, glue 6 pieces of lid 67°67 on the nail 69.69...
When ... is piled up, the comb-like bush 74 becomes the rod 68.
, 68 . . .
．． The stack of bar-shaped stacks 2, 2, . . . stacked vertically on top of each other is pushed into the packaging box 75.

Next, the table 62 is raised by the chain 66.66,
Go into the lower position of the lifter 67.67...

Next, the piston of the cylinder 72.72 is attached to the presser foot 73,
73 is lowered, and the claws 69 and 69 are rotated upward to lifter 6.
7. It comes off from both sides of 67.

Next, the table 62 is lowered by the chain 66.66,
All glue lids 67, 67... and table 62
returns to the position shown.

At this time, the cylinder 88 presses the centers of the claws 82 and 83 downward, and moves the claws 82 and 83 to a position where they do not engage with the lifter 67.

Tray 31° 31 on which a group of bar-shaped stacked bodies 2 is placed again.
The lifter 67 rises each time the ... is sent to the packaging position, and the same operation is repeated thereafter.

As described above, in the present invention, the trays for feeding the bar-shaped stacks are arranged alternately, for example, trays on which the bar-shaped stacks of paper chips are placed with their ridges shifted from each other. The stacks can be arranged horizontally, vertically, and horizontally with their ridges intricately arranged, so that the bar-shaped stacks are adjacent to each other at the shortest possible distance, and the ridges can be efficiently damaged or dislocated using the minimum volume. It can be stored in a packaging box in a stable state.

Furthermore, since the device does not require a special drive mechanism, it has a simple structure and can be provided at low cost.

Furthermore, since the trays on which the rod-like intussusceptions are placed are arranged in groups of adjacent trays, the ridges of the vertically adjacent rod-like intussusceptions in each group are naturally shifted from each other, and the rod-like intussusceptions can be placed vertically adjacent to each other at the shortest possible distance.
