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

[0002]

2. Description of the Related Art Conventionally, the following devices have been installed in the delivery section of a single-sided bag making machine. For example, it has a mechanism that vibrates the backing plate installed on the top of the timing conveyor belt and a mechanism that receives the temporary product, and the bags separated and cut by the bag making machine one by one fall at the cutting position and the timing Overlapping on the conveyor. At that time, after the bags were aligned by a jogger and formed into a certain number of bundles, a temporary product receiver was moved above the bags to convey a certain number of bundles of bags with a timing conveyor belt.

At this time, the operator arranges a certain number of bags in a bundle and conducts a quality inspection for processing defects. Furthermore, the bundle bag is banded and packed in cardboard. However, the above-mentioned conventional technique has the following problems. That is, in a multi-sided bag making machine with two or more chamfers, the bags are dropped in a state of being close to their neighbors after cutting and discharged onto the timing conveyor, so that the directions of the sacks are not constant and the adjacent sacks overlap. Therefore, they cannot be separated and aligned, and in the conventional method,
The problem is that it is not automated, and all work is done manually, and it takes a lot of time to separate and arrange the work.

Further, there are the following devices as the devices to be installed in the delivery section of another multi-sided bag making machine. For example, immediately after cutting with a bag-making machine, the bag is dropped onto a conveyor partitioned by guides and linearly conveyed between plate-shaped guides. However, the above-mentioned conventional technique has the following problems. The bag was transported by a conveyor. Also, the guide was made movable to accommodate various sizes. For this reason, it is unavoidable that there is a gap between the conveyor and the guide,
The bag was caught in this gap, which resulted in poor conveyance. Further, during high-speed transfer, the work is rough and tilted on the conveyor, which causes transfer failure.

Further, due to the improvement in performance of the bag-making machine and the increase in the number of chamfers, the work after delivery of the bag-making machine is
There was a problem that it could not be handled by manual work. In addition, even if the form of the bag is the same, there are many conditions due to differences in size and material, which makes automation of delivery work of the bag making machine more difficult.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide an apparatus for automating the delivery process of a bag making machine without increasing the apparatus size. To do.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an automatic device for a delivery process of a multi-sided bag making machine for making bags in a plurality of rows at the same time.
That is, (a) a mechanism for sandwiching the bag near the center of the bag with a belt and linearly conveying it without dropping the bag immediately after cutting with the bag-making machine, (b) a mechanism for inspecting the quality of the bag, (c)
A mechanism that rotates the flaps and conveys them independently from non-defective products for sampling inspection and unloading defective products, (d)
A mechanism for inserting a plate-shaped guide between adjacent bags during conveyance, (e) a mechanism for dropping and simultaneously aligning the bags, (f) a mechanism for holding the falling position of the bags constant, (g)
A delivery device for a bag-making machine comprising: (h) a mechanism for temporarily receiving a bag for separating a certain number of bundles, a mechanism for compressing the thickness of a certain number of bundles, and (a) to (h) above. .

[0008]

The mechanism (a) to (h), which is a feature of the present invention, works as follows. That is, (a) the bag discharged from the bag-making machine is cut off on the guide having the same height position, so that the disorder after cutting the work is prevented. Immediately after cutting, it is sent to the transport mechanism by a touch roller that operates in synchronization with the cutter of the bag making machine. The upper and lower belts are sandwiched around the center of the bag and transported. Since the bag is always supported by rollers and belts,
It keeps the state before cutting with a bag-making machine and is transported without being affected by the warp, thickness and material of the bag. (B) The positioned bag is subjected to image processing by a camera (sensor) and quality inspection is performed. (C) By rotating the flap, the bag for sampling inspection and carrying out defective products is conveyed to a path independent of the non-defective product work. (D) The bag discharged from the bag-making machine is in a state of being closely attached in the lateral direction. As the center of the bag is sandwiched by the belt and conveyed, an inclined plate-shaped guide is gradually inserted from the lower side to push up the end of the bag, thereby separating adjacent bags from each other. (E) The bag is abutted and aligned by reciprocating the jogger in the flow direction at the same timing as dropping the bag into the stacker box. (F) When the number of bags to be stacked per bundle is large,
The lower the bag, the greater the drop distance. At this time, the bag may be caught in the guide and jamming may occur.
In order to prevent this, the position of the base on which the bags are placed is lowered according to the number of stacked bags, so that the distance of dropping of the work is made constant. (G) After a certain number of bags, a plate for receiving a temporary product is put on the stacked bags to make a stack of a certain number of bags in a stacker box. (H) In order to suppress variation in the thickness of the bag due to curl within a certain range, a bundle of a certain number of bags is compressed from above.
