This invention relates to the provision of an automatic packaging machine that is fully automatic.

It is common practice to store small items and other target items made of various fabrics in bags made of transparent or semi-transparent plastic film to produce products. This is done separately from the automatic packaging means, that is, the bag making machine (therefore, a separate process in which a large number of bags manufactured by the machine are transported to an automatic packaging machine, taken out one by one, and then loaded with the desired product). process is adopted.

Therefore, there is a lot of loss in terms of efficiency and production costs, and it is extremely difficult to carry out a continuous process in which long material fills are made into bags and the target articles are placed in each of the bags made. It's advantageous. In addition, in conventional bag making machines and packaging machines, for example, in bag making machines,
Occurrence of strange odors during adhesive application, disconnection of fuse heaters, stability of bag bottom shape means, etc.
There are problems with low accuracy, etc. In packaging machines, for example, there are problems such as difficulty in loading articles accurately and smoothly, instability,
There are still some problems in J:L, such as the unreliability of sealing the bag opening and the unacceptably slow processing speed. There are many things.

The present invention is based on these OI! One of the ways to meet this demand is to automatically obtain nine bags from a continuous long film material that are approximately rectangular in shape and have adhesive applied to the open raw sides. A series of processes ranging from bag making to product production, including automatic charging and sealing of the bag opening.
This can be done with high efficiency using a single machine.

The centering degree of d) can be used later as a tab for sealing the bag.Thus, the film (1) that has exited the half-folding device (3) is transferred to the next adhesive applicator 1 (97[ By feeding, a band-shaped adhesive layer α is formed by the adhesive application member αG.
This is what η wears! Il! Adhesive layer On the adhesive layer 71 Immediately after application, the adhesive is passed through the sealed drying member α9, thereby making it possible to easily process the adhesive without producing any strange or offensive odors. There is no problem at all, so it is a stone. Furthermore, the semi-folded film (1) that came out of this device (9)? By feeding the film fusing device QOK, there is a fixed fusing heater (c) and a movable film pressing row that can move forward and backward toward the same heater 6 and 4. (To)
By doing this, the half-folded film (1) can be melt-cut across the width direction, with the fold (!b) serving as the bottom and the pair of melt-cut parts serving as the two sides G61, and the adhesive layer The protruding side edge with apertures can be used as the sealing tongue piece 1411 for an open bag body (original) very quickly and easily, and the device (31
(9) Ql) It can be obtained through three steps using K. Furthermore, in the present invention, the heater for M is completely fixed and immovable per [111FllrK], and the film pressing roller (2) is moved back and forth in the evening to contact and melt the film (1), so the heater is not used as in the conventional method. In those that perform bathing by moving toward and away from the film (1), the heater □□
The heater lead wires (!lb) and sensor lead wires (!ad) are bent and perturbed repeatedly due to the movement of the □, so they are stable and stable without disconnection or failure to conduct electricity. Welding 11r can be carried out with high reliability over a long period of time, and due to the tension of the film by the roller surface and the linear trailing edge, there is no distortion or other snoring rub μ in the welding line, and the bag has a good finish. That is.

In the present invention, the individual bags (11) that have come out of the film fusing device α0 are immediately sent to a work conveyor (■) and an article loading device QnK having an article loading conveyor 011, thereby producing bags (11). The loading of articles into the bag can now be carried out continuously without any time loss, and the bags, which were previously manufactured separately and torn apart, are transported to the packaging machine and thin (8 types of bags! There is no loss pipe in the process of taking out one sheet and loading the article into it, and efficient continuous work can be achieved as assembly line work.This charging device a5#IcjIP%A
However, by suction fixing near the opening of the bag body (L&) at the article loading position and retracting the sealing platform 3s piece (4I) downward, the opening can be opened and expanded through air injection and the interior of the bag can be expanded. Expansion shaping is carried out via the air guide plate 1, and the target article to be fed from the charging conveyor (2) is transferred to the transfer architrave and the circular charging piece t5 on the same table.
Through the intervention of DIυ, it is possible to quickly and straightly charge the work conveyor (■) and the charging conveyor (61) very smoothly and without fear of stagnation, catch, or slanted charging. By appropriately designing the length, it is possible to load articles into a large number of bags (18) that are being moved one after another without difficulty. Furthermore, by connecting the tongue sealing device 111KII opposite to the article loading position of the article loading device (1), it is possible to completely seal the article 1 by loading the article (1 &). In the tongue-sealing device of the present invention, which allows for immediate final packaging, the upright holding surface (fi?b) of the sloping ejection path section can be used in forward and reverse directions. A conveyor hammer for sealing that is rotatable and whose one end is elastically supported, a rotatable sealing roller that is in a fixed position facing the conveyor book, and a pressing member for the bag (cta) that is located on the potted soil of the conveyor 84 - From each installation and combination 1llllK, the sealing tongue ID, which is easily deformed by rocking, is held upright in advance, and the pressing member m is used to apply pre-expanding pressure and shaping of the tongue ←υ sticking part of the bag body (I@) K. , between the sealing roller and the belt elastically supported by a spring, the opening of the bag body (1a) and the tongue 11 are connected; By unrolling the tongue without any slack and passing it under pressure #1S, the sealing tongue (2) is completely expanded and tightly adhered to the opening without any fear of wrinkling, shifting, or curling, resulting in a good appearance. It can be sealed from the beginning, and completed packages can be produced one after another through forward and reverse transport on a conveyor. According to this Qll, the entire machinery and equipment is equipped with fl(3)
(9) If it is established by the base part of QO (1m)-, the work process can be reduced to 7N in just 5 steps of each device, making it compact and economical with a significant reduction in the number of personnel required for work. The machine of the present invention can perform the function of an efficient automatic product packaging machine, and after feeding plastic film (1) as a raw material into the machine, the machine waits for products throughout the entire process, and does not require dead stock. It is continuous and continuous flow work without causing any problems, and the necessary mechanisms in each device are relatively simple, and the movements in each device are not complicated, so there is little risk of failure. Automatic flli control is easy, and although the type of product does not matter, it has great versatility and is excellent as an automatic packaging machine for small items that are relatively small.
