Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method of stacking bags containing a large number of small lumps of root vegetables, candy, and other ball-shaped items in a low-volume manner in the shape of a so-called ``Shogi boat'' or a ``Shogi-topped'' shape. This relates to a device that facilitates arranging and packing boxes.

Conventionally, balls of candy such as candies, which may or may not be individually covered and wrapped with cellophane paper, root vegetables such as small frozen taro, and other small lumps, are counted and weighed to a predetermined number or weight. It is sealed in a bag made of polypropylene, polyethylene, etc. without being filled, but because the shape is not a fixed shape and the contents move, it is packed in bags of 1 dozen or 1 bag. To box multiple items such as gloss,
The most efficient method is to shift and stack each item storage bag in a so-called ``sashimi-like'' manner, and then stack each item in multiple layers with each layer facing outward.
Filling and packaging was done manually.

FIG. 1 shows a longitudinal section of the boxed state.

Counting of the stored items, storing them in bags, etc. are performed automatically and mechanized on a belt holder, but in the final packaging process, labor costs are high because the ``sashimi-like'' alignment is done manually, and automatic labor-saving is highly desired. A device has been devised that grasps the article storage bag, transfers it into a box, and shifts and stacks the bags one by one, but this device is large-scale, expensive, and unsuitable for use with inexpensive articles.

The present invention is an article storage bag aligning device that can shift and stack article storage bags without requiring human labor by simply adding a device with a simple configuration to a conventional device. Based on the following, the present invention will be explained in detail.

The main points of the present invention are as shown in FIGS. 2 and 3, the accumulating belt conveyor 7 provided continuously to the conveyor belt conveyor A, and the stop plate 10 vertically installed close to the upper part of the accumulating belt conveyor 7.
+, 10□ in the alignment device B1, (B2).

The conveyor belt conveyor A is configured endlessly,
In addition, a hopper C for supplying a fixed amount (constant number) of ball-shaped articles 9 such as candy, a bag fusing device (not shown), etc. are attached to the predetermined position, and the hopper C rotates in the direction of the arrow in the figure. In the figure, 2 indicates a belt pulley.

In Fig. 2, A' is a belt conveyor for interval adjustment;
The conveyor belt is provided endlessly in close proximity to the extension of the conveyor belt conveyor A, and rotates at a higher speed than the conveyor belt conveyor A.
The belt pulley 5' at the front end has a predetermined times larger diameter than the belt pulley 5 at the rear end.
A reversing chute 6 having a transversely parabolic cross section is provided surrounding the vicinity of the exit side.

The accumulating belt conveyor 7 of the accumulating device B1 is parallel to the interval adjustment belt conveyor A', and is shifted slightly forward just below it to become an endless belt conveyor of a predetermined length and a predetermined rotation speed lower than the interval adjustment belt conveyor. It is configured. 8.8'' rotates in the same direction as the conveyor belt conveyor and the belt wheel of the interval adjustment belt conveyor.

The restraining plates 102, 102 are vertically installed above the accumulating belt conveyor 7 at a predetermined distance, and the restraining plates 101 are arranged in the extending direction of the outlet 6'' of the reversing chute 6 (toward the rear of the accumulating belt conveyor 7). In addition, a restraining plate 102 is provided in front of the outlet 6' to prevent the article storage bags from falling from the reversing chute and moving forward at the front and rear sides, and to prevent the article storage bags from falling in the front and rear portions of the article storage bags within a predetermined length range. The boxes are stacked one on top of the other in a staggered manner.The dimension of "L" is approximately equal to the length L of the box to be packed.

FIG. 3 shows the alignment device B2 without a reversing chute, in which the accumulating belt conveyor 7 is provided in an extension form just below the front end of the conveyor belt conveyor A, and the stop plate 10,
is installed vertically at the front of the accumulating belt conveyor 7, and the stop plate 10□ is installed vertically at the rear, respectively, and the front and rear belt pulleys 8.8 rotate in the opposite direction to the belt pulley 2 of the conveyor belt conveyor A. ing.

FIG. 7 is a schematic plan view of an automatic bagging device equipped with the article storage bag alignment device of the present invention, and FIG. 8 is a side view of the same, in which the article storage bag alignment device is provided in the middle of the base, The alignment device B
A pusher device 14 is installed on one side of B2 or B2, a turntable 17 is installed on the pond side, and a packaging box 2 is installed outside of the turntable 17.
A carry-out conveyor 19 is provided parallel to the front-rear direction of the base. In the figure, 15 is a geared motor with a clutch brake 16 is a crank arm, 18 is an F-chuck, and 21 is a reverse low rear actuator.

The operation of the article storage bag aligning device of the present invention having the above configuration is as follows.

In the automatic bagging device shown in Fig. 2, counting (weighing) is performed from hoppers C at predetermined locations on a rather hard plastic sheet a, which is unfolded with the inner surface facing up, on a conveyor belt conveyor.
Then, a bag-making device (not shown) at a predetermined position folds the sheet at predetermined places and heat-seals it to form a bag with its surface. is below,
Therefore, the trademark, etc. in the trademark, etc. display area b' is on the bottom side, and the back side is on the top, and the back side and the center of the top surface of the trademark, etc. display area, the opening edge at the opposite end of the trademark, etc. display area, etc. are each integral. The article storage bag 31 is formed into a solid plate by heat sealing, and in this state, the article enclosing bag 31 is transported forward to a high-speed interval adjustment belt conveyor A1. On the high-speed belt, the distance between the next article storage bag 32 on the belt 4 becomes wider, and while rapidly rotating inside the chute 6, the bag 32 moves from the exit 6' to the accumulation belt conveyor 7 immediately below. When the belt falls upward, it hits the stopper plate 101 at the rear end and is prevented from falling unexpectedly, and is transported forward by the rotation of the belt, hits the stopper plate 102 at the front end and remains in that position, while the belt is rotating continuously. Further, due to the above-mentioned inversion and fall, the articles in the bag are gathered together at the rear of the bag, and the trademark stop display part b becomes the front end, turned inside out, and exposed on the top surface.

In the meantime, the next article storage bag 32 with a required interval is similarly dropped from the reversing chute 6 and is reversed, turned upside down and moved forward, and the front half of the bag 32 is moved forward due to the protrusion of the rigid plate-like part at the front end. The next three article storage bags 3 are placed on top of the previous article storage bag 32 from the rigid plate-like part (1), and the two subsequent article storage bags 32 are stacked on top of each other. Lay three bags on top of each other at a specified length between the boards.

Front and rear restraining plates 10. ．． When the article-containing bags are piled up in a "sashimi-like" manner between 102 and 102, the pusher 14 advances from the outside as the crank arm 16 rotates in synchronization with the above-mentioned process to stack the article-containing bags in the "sashimi-like" manner. One row is pushed onto a turntable, and the lowered F-chuck 18 securely grips the one row as it is, and is transferred and packed into a packaging box 20.

When the 1st f rows are packed, the 1st row of the 2nd row is rotated 180 degrees on the turntable by the clear actuator 21 and packed into boxes, so that each row is alternately packed in the 1st row as shown in Figure 1. The direction is changed and the bulk is stacked on top of each other.

The alignment device shown in FIG. 3 arranges each article storage bag 3j, 3
・ is transferred on the conveyor belt conveyor at predetermined intervals, and the bag is dropped onto the accumulating belt conveyor B2, which has relatively high frictional resistance, so that the dropped article storage bag rotates at a predetermined speed. The accumulating belt conveyor 7 sequentially hits the stop plates 101 and reliably transfers them to the stop plate 102 side in the opposite direction, and similarly to the above-mentioned alignment device B, the article storage bags 32...
・ are stacked like ``sashimi'' and automatically packed in boxes using a butsusha 14, etc.

The above describes the accumulation of three bags, but the number may be determined as necessary, and the distance between the two stopper plates may be determined in accordance with the length L of the box.

The above has described an aligning device for packing boxes made of relatively hard material bags, but when arranging soft material bags or vacuum-packed plate-shaped foods such as frozen hamburgers, the first bag is An inclined member 11 is attached to the inner surface of the lower end of the restraining plate, or alternatively, an inclined member 13 is provided which projects into the central gap of the accumulating belt conveyor 7 by sensing the dropping of bags or by using a spring or lever action. 13... are provided so as to be freely visible and retractable to lift the front part of the bag and tilt the bag to make it easier for the next bag to ride on it, so that it can be stacked in a ``sashimi-like'' manner.

The article storage bag aligning device of the present invention having the above-described configuration and operation has the following effects.

An integrated belt conveyor 7 that can accommodate one box of various sizes,
The dimension of the box in which multiple single rows of ``sashimi-like'' goods storage bags are packed is approximately the dimension between the two dividing plates 101.10□ L.
By simply adding an alignment device with a simple structure in which the restraining plates 101 and 102 are installed slightly above the conventional conveyor belt conveyor A, the article storage bags that have fallen onto the accumulating belt conveyor 7 can be moved to the opposite side. The bag is transferred to the point where it hits the stop plate and placed there, and then the next bag, one after the other, is moved in the same way, and the front part rests on the previous bag, causing it to shift and overlap in a so-called "sashimi-like" manner. This eliminates the hassle and time of manually waiting for the transfer of a plurality of article storage bags and stacking them on top of each other.

Therefore, the subsequent packaging work can be automated in a synchronous manner, and all processes of weighing (counting), bag making, packaging in bags, arranging in a boat shape, and packaging are performed at low cost and with reliable workability. This was made possible by the device.
