Description

[Detailed explanation of the invention] (a) Industrial application field This invention can be used, for example, to create a single pouch containing items such as vinegar, sesame, and kanpiyo used as ingredients for sushi. This invention relates to a packing device used for bagging.

(B) Conventional technology Conventionally, the above-mentioned packing device opens the mouth of a parent bag made of vinyl chloride or the like upward, and then vertically drops a plurality of child bags at once to the parent bag. It has a vertical storage structure.

(c) Problems to be solved by the invention However, with the above-mentioned vertical packing device, multiple child bags may become separated during the fall, or may rotate and be oriented unevenly, and the opened parent bag may Because a part of the child bag protrudes from the mouth, one of the falling child bags comes into contact with the mouth of the parent bag, and the child bag gets caught in the mouth of the parent bag and is not stored smoothly. There is a problem in that mistakes occur frequently in the bagging work of child bags.

Furthermore, as a means to solve the above-mentioned problems, for example, if multiple child bags are packed one by one into one parent bag, the bagging process takes time and effort, and work efficiency decreases. There is a problem.

The object of this invention is to provide a packing device that can smoothly and reliably pack a plurality of child bags of different sizes into one parent bag, and can also achieve high-speed bag filling.

(d) Means for solving the problem This invention consists of a first conveyor that stacks a plurality of irregularly shaped pouches containing articles on a tray and intermittently transports the plurality of trays at the same time; A second conveyor that intermittently transports a plurality of trays of parent bags enclosing child bags of the same shape is arranged in parallel at a predetermined interval, and is disposed on the downstream side of the first conveyor. bag storage means for horizontally moving a plurality of odd-shaped child bags for a plurality of trays placed on a conveyor and simultaneously storing them in a plurality of parent bags transferred to a second conveyor; A bag opening means is disposed between the conveyor and simultaneously opens the mouths of a plurality of parent bags transferred to the second conveyor, and a bag loading section is disposed on the front stage side of the second conveyor. and a bag transfer means for simultaneously transferring a plurality of parent bags loaded into a second conveyor onto a second conveyor, and a plurality of trays on which oddly shaped child bags are placed are arranged at predetermined equal intervals in the longitudinal direction of the first conveyor. The tray has a first recess provided with an upper placement surface for placing a large child pouch and front and rear regulating surfaces, and a first recess provided approximately in the middle of the upper placement surface for placing a small child pouch. The pack device is characterized in that a second recessed portion having a lower placing surface and front and rear regulating surfaces is formed parallel to the moving direction of the bag storing means.

(E) Effect According to the packing device of this invention, a plurality of child bags are placed one set at a time on the front side of the first conveyor which is intermittently driven for a plurality of trays at the same time. The bag opening means is driven to simultaneously transfer a plurality of parent bags taken out from the bag loading section to the front stage side of the second conveyor, and simultaneously open the mouths of the plurality of parent bags by driving the bag opening means. At the same time, the bag storage means is driven to horizontally move the bag trays worth of child bags to the downstream side of the first conveyor. After a plurality of parent bags are simultaneously stored, the second conveyor is intermittently driven for a plurality of trays at the same time to convey the parent bags to the next process.

In addition, since the tray on the first conveyor side has a first recess for placing a large child bag and a second recess for placing a small child bag, each of these child bags can be positioned according to the front and rear regulating surfaces. The transport is controlled while maintaining a stable state in which large child bags are stacked on top of small child bags.

(f) Effect of the invention In this way, a plurality of irregularly shaped child pouches are moved horizontally one by one and stored in the main bag while being stacked in a stacked state corresponding to the size of the mouth of the main bag. A plurality of irregularly shaped child bags can be stored in a parent bag at once without the child bags getting caught in the part.

Moreover, since multiple trays are processed simultaneously,
This has the effect of significantly speeding up bag filling.

In addition, the tray on the first conveyor side mentioned above has
Since the first recess and the second recess each have a front and rear restriction surface and a placement surface, the position of a plurality of irregularly shaped child pouches is regulated by the front and rear restriction surfaces, so that the position is always stable. It can be transported while maintaining its position.

In other words, it is possible to prevent the displacement of each child bag due to inertia between when the intermittent drive of the first conveyor starts and when the intermittent drive stops, and it is possible to convey the child bags while always maintaining the positional relationship between the upper and lower child bags in a fixed position.

Furthermore, since the structure is such that a small child pouch is placed in the second recess on the lower side and a large child pouch is placed in the first recess on the upper side, space efficiency is good, and even though the placement space is relatively small, It is possible to stably transport a plurality of irregularly shaped child bags while aligning them on the tray, and it is possible to reduce the size of the tray itself.

Furthermore, since the second recess is formed at approximately the middle lower part of the upper placement surface of the first recess, the small child bag is positioned corresponding to the opening position of the parent bag that is opened the largest by the bag opening means. Therefore, there is no need for a special guide part for further enlarging the opening end of the main bag, and the structure of the bag opening means and the bag storage means can be simplified.

As a result, a plurality of irregularly shaped child bags can be smoothly and reliably stored in the parent bag, and the bag filling operation can be carried out at high speed.

Since the structure is such that the tray 4 is placed on the tray 4, space efficiency is good, and a plurality of irregularly shaped child bags 2b, 2a can be arranged and placed on the tray 4 and transported stably even though the placement space is relatively small. This has the effect that the tray 4 itself can be made smaller.

Furthermore, since the second recess 42 is formed at approximately the middle lower part of the upper placement surface 4b of the first recess 41, the small child is placed at the opening position of the main bag 19 where the bag opening means (see suction element 25) opens the largest. The bag 2a is positioned correspondingly, and therefore a special guide part for further enlarging the open end of the main bag 19 is not required, and the bag opening means (see suction member 25) and bag storage means (pusher plate) are not required. This has the effect of simplifying the structure (see 16).

As a result, the plurality of irregularly shaped child bags 2b, 2a can be smoothly and reliably stored in the parent bag 19, and the bagging operation can be speeded up.

In terms of the correspondence between the structure of this invention and the above-mentioned embodiment, the bag storage means of this invention corresponds to the pusher plate 16 of the above-mentioned embodiment, and the bag opening means corresponds to the suction member 25 in the same manner. Although the bag transfer means corresponds to the suction element, the present invention is not limited to the configuration of the above-described embodiment.
