Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated device for a delivery work process in a bag making machine.

[0002]

2. Description of the Related Art Conventionally, there have been the following devices (not shown) installed in the delivery section of a bag making machine for single-chamfering. For example, it has a mechanism for vibrating the backing plate installed on the top of the timing conveyor belt and a mechanism for temporarily receiving the product, and the bags separated and cut one by one in the bag making machine fall at the cutting position. Stacked on the timing conveyor. At that time, the bags were bundled by a timing conveyor belt by arranging the bags with a gathering board and forming a bundle of a fixed number of pieces, and then moving a temporary product receiver above the bags. . At this time, the worker had to arrange a certain number of bags in a bundle, inspect the quality of processing defects, band the bags in a bundle, and pack them in a cardboard box.

Therefore, the following problems have arisen in the above-described conventional working process. That is, in a bag making machine with two or more chamfers, the bag is dropped in a state of being close to an adjacent bag after being cut into one sheet, and then discharged onto the timing conveyor. It was not uniform, and it was difficult for adjacent bags to overlap or separate and be aligned.

[0004]

However, in the above-mentioned conventional apparatus for the delivery work process, automation has been delayed, and all the work is performed manually. For this reason, there has been a problem that it takes a lot of time to separate and arrange them. Further, as the performance of the bag-making machine is improved to increase the speed, the delivery work process in the bag-making machine cannot be handled manually.

Further, even if the bag to be manufactured has the same shape, the manufacturing conditions are increased due to the difference in size and material, which makes it more difficult to automate the delivery work process in the bag making machine.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide an automation device for a delivery work process in a bag making machine.

(D) A mechanism for post-processing such as punching the corners of the bag round
(E) An automatic device for a delivery work process in a bag-making machine, which is provided with a mechanism for dropping the bags and bundling them into a predetermined number at a time and aligning them.

[0008]

In the automated device for the delivery work process of the present invention, the features (a) to (e) described above function as follows. That is, (a) the bag discharged from the bag making machine is cut off on the guide having the same height position, and immediately after cutting, the bag is sent to the oblique conveyance belt by the touch roller. Therefore, the direction of the bag is kept in the state before being cut by the bag-making machine, and the interval between the adjacent multi-faced bags is widened without being affected by the warp, thickness and material of the bag. (B) The position of the bag is determined by the rotating positioning roller installed in the lower part and pressed against the guide, so that the position is adjusted without being affected by the size of the bag. (C) The positioned bag is subjected to image processing by a camera (sensor), quality inspection is performed, and defective products are discharged. (D) Post-processing such as punching the corners of the bag round by lowering the punching cutter with respect to the positioned bag. (E) The bag is dropped into the storage box, and the two-sided approach plates are reciprocally moved in conformity with the timing sensor to abut against the bag for alignment. Furthermore, after reaching a certain number,
By inserting a plate for receiving the temporary product on the stacked bags, a bundle of a certain number of bags is collected in a storage box. The automated device for the delivery work process having the above functions eliminates manual work and significantly improves work efficiency.
