Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an upright conveyance device for flat conveyed objects, for example, packaged rice crackers wrapped one by one.

(Prior Art) Food products such as rice crackers are individually wrapped in packaging materials to prevent moisture, and the food items are stacked in one direction and sequentially packed into large bags. This allows for more compact packaging,
In addition, attempts are made to give consumers a feeling of orderliness, luxury, etc., and to encourage consumers' desire to purchase.

By the way, in order to pack the packages containing rice crackers and the like into large bags in a state where they are stacked in one direction as described above, conventionally, a worker is positioned near the conveyor belt and the workers are placed next to the conveyor belt. They grasped the packages with their hands and stacked the packages in one direction in a large bag and stuffed them one by one from the bottom upwards. Therefore, manual work by such workers requires considerable speed because it has to match the constant conveyance speed of the conveyor belt, and is harsh labor for the workers.

(Purpose) The present invention was developed in view of the above-mentioned circumstances, and its purpose is to automatically pack a group of flat conveyed objects into a large bag. The object of the present invention is to raise a group of flat objects to be erected and to transport them while maintaining the erected state.

(Structure of the invention) In order to achieve the above object, the present invention includes a conveyance path for guiding a group of flat conveyed objects, and a conveyor path that protrudes from the conveyance path and extends toward the end of the conveyance path. a conveyance claw for press-conveying a flat conveyed object; and a conveyance claw provided on the conveyance path in the direction in which the conveyance path extends;
a first endless member whose relative speed is lower than that of the conveyance pawl; and a second endless member driven substantially in accordance with the speed of.

From the above-mentioned configuration, a group of flat objects to be conveyed by the conveyance claws is erected by the first endless member, and after being erected, the group is maintained in the erected state by the second endless member. flat objects are transported. Therefore, it is sufficient to transport a group of flat objects in an upright state up to the large bag filling process, and then to fold down the upright state of the group of flat objects and arrange them one on top of the other in one direction. Compared to the case where a group of flat objects are transported in a state where the objects are flattened, it is possible to pack them into large bags more reliably and accurately.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an upright conveyance device according to the present invention, and the upright conveyance device 1 includes a conveyance path 2.
, a transport claw 3, an endless belt 4 as a first endless member, and an endless belt 5 as a second endless member.

The conveyance path 2 extends in one direction, and a predetermined number (hereinafter referred to as a group) of flat conveyance objects 6, for example, packaged rice crackers wrapped one by one with a wrapping material, are guided through the conveyance path 2.

A rotational drive source (not shown) is provided at the terminal end of the conveyance path 2.
A shaft 7 is provided, and a pair of sprockets 8 are attached to the shaft 7. On the other hand, on the starting end side of the conveyance path 2, a shaft (not shown) is rotatably supported by a frame (not shown), and a sprocket (not shown) opposite to the pair of sprockets 8 is mounted on the shaft. installed. A pair of endless chains 9 are stretched between these sprockets 8 (one not shown), and these endless chains 9 are located below both sides of the conveyance path 2 and in the extending direction of the conveyance path 2. It will be placed in Each of the pair of endless chains 9 supports an L-shaped transport claw 3 so as to be swingable at predetermined intervals. This conveying claw 3 is composed of a foot portion 11 and a standing portion 12, and the foot portion 11 is heavier than the standing portion 12. This conveying claw 3 has a function of pressing and conveying a group of flat conveyed objects 6 in the left direction in FIGS. 1 and 2, and the conveying claw 3
When conveying under pressure, the foot portion 11 is pressed against the guide surface 1.
3, and the upright portion 12 presses against a group of flat objects 6. On the other hand, a group of flat conveyed objects 6
From the position where the pressure conveyance function is stopped, the guide surface 13 is cut out, and the conveyance claw 3 moves clockwise in FIG. sway to.

A notch 14 is formed in the center of the conveyance path 2 in the direction in which the conveyance path 2 extends, and the endless belt 4 faces from this notch 14 so as to be substantially flush with the conveyance path 2. I'm here. In this embodiment, the endless belt 4 is driven in the same direction as the driving direction of the conveyance claw 3 (to the left in FIGS. 1 and 2) at a slower speed than the conveyance claw 10.

On both sides of the conveyance path 2, there are a pair of shafts 15 linked to a rotational drive source (not shown) and a pair of shafts 16 facing the pair of shafts 15 in the extending direction of the conveyance path 2. The shafts 15, 16 are provided with rollers 17, 17, 18, 1 at their tips, respectively.
8 is installed. A pair of endless belts 5 are stretched between the rollers 17, 17 and rollers 18, 18, respectively, and the surfaces of the pair of endless belts 5 on the conveyance path 2 side are respectively connected to a group of flat conveyed objects. It is located in the contact area of 6. The pair of endless belts 5 are driven in the same direction as the driving direction of the conveying claws 3 at the same speed as the conveying claws 3 or at a slightly slower speed.

In addition, 19 is a fall prevention mechanism which forms a part of a direction change mechanism, and 20 is a gutter.

Next, the effect will be explained.

A group of flat conveyed objects 6 that have been arranged one on top of the other in the conveying direction in the previous process are conveyed under pressure toward the end of the conveying path 2 by the conveying claws 3 . A group of flat conveyed objects 6
When the objects are placed on the endless belt 4, the relative speed of the endless belt 4 is slower than that of the conveying claws 3, so the group of flat conveyed objects 6 is driven by the conveying claws 3 toward the end of the conveying path 2. He stood up as he
The group of flat conveyed objects 6 that stood up comes into contact with the surfaces of the pair of endless belts 5. Since the pair of endless belts 5 are driven in the same direction as the driving direction of the conveying claws 3 at the same speed or at a slightly slower speed, the group of flat conveyed objects 6 that have stood up are conveyed while maintaining their upright state. Ru. When the group of flat transported objects 6 reaches the end of the pair of endless belts 5, the direction of the group of flat transported objects 6 is changed by a series of direction changing mechanisms and taken into the gutter 20. Then, while the group of flat conveyed objects 6 is maintained in an upright state by an upright maintenance means (not shown) provided in this gutter 20, the group of flat conveyed objects 6 is conveyed to the next process, a large bag filling process. .

Although one embodiment has been described above, in the present invention, the flat conveyed object may be a napkin, a portable tissue, or the like.

(Effect of the invention) As is clear from the above description, the present invention is capable of standing up flat conveyed objects stacked in the conveying direction and conveying the raised flat conveyed objects while maintaining the upright state. Can be done.
