。[Detailed description of the invention] (Summer)...Prior art and its problems The plastic film automatic packaging device that has been widely used in the past, that is, the automatic packaging device that wraps and wraps a wide plastic film around the circumference of an article, is , plastic film rolls a+ta'i are placed oppositely on the upper and lower sides of the transport line l of the article P to be packaged, and the upper and lower rolls are connected by connecting the film f1, (/r) of both rolls with additional rolls of 31,3'l. Collection a1, a'
The conveyor line l
The above article P is suitably conveyed, a film f is wrapped around its circumferential surface, and the edge of the wrapped film is pressed, for example, by a presser roller,
At the same time, the film is welded and cut using a heat seal cutting device equipped with a tightening roller. That is, for example, the film is cut using an electric heater wire, and at the same time, the film is cut using an electric ribbon heater. Seal the edges (weld)
Then, the article P is automatically wrapped. (
(See Figure 3.) However, in the case of the above-mentioned conventional device, one winder is installed at the top and one at the top, and the wrapping work is performed by connecting the two films. Therefore, if the film on one or both of the winding bodies a and a' 1 runs out, the entire device must be temporarily stopped and a new winding body must be replaced and installed. .

な課題とされてきたものである。This is due to the fact that the packaging process is always carried out automatically and continuously along the conveyance line, and that not only the packaging process but also the processes before and after this process are continuous process cycles in which the packaging equipment is used. Since it is often incorporated as a part of the packaging equipment, it has a huge impact that cannot be solved by just temporarily stopping the packaging equipment, so it is necessary to ensure that film supply can be carried out without interruption. This has been considered a serious issue.

ものである。That is, to explain the configuration of the present invention with reference to embodiments, there is a film supply mechanism A consisting of a pair of rolls a1 and a2 and a heat seal cut device, and a film supply mechanism A that also includes a pair of rolls a'1 and a'.
A film supply mechanism A' consisting of a heat seal cutting device b' and a heat seal cutting device b' are arranged vertically opposite to each other across a conveyance line l. It consists of fixed members b1, bl+ and movable members b2), b3, b/z, b'3 placed opposite to the left and right thereof, each movable member being exclusive to one winding body and facing the fixed member. The device is provided so that it can be moved forward and backward by appropriate means, and the entire device is constructed by providing an appropriate structure for cutting and welding (sealing) the film by heating it on one or both of the fixed member and the movable member. , the film fl pulled out from each one of the winding bodies of the film supply mechanisms A and A' arranged vertically opposite each other, for example aI and 72;
The end of f'2 is connected through between the movable member b2), bla, exclusive to the winding body ai, /2, and the fixed members b1, blt, and the film is stretched vertically across the conveyance line. and each of the other winding bodies a2) and a'

The film f1 pulled out from the winding body a1 of the film supply mechanism A and the film (/2) pulled out from the winding body a1 of the mechanism A' are connected and stretched vertically. Film f2 pulled out from roll a2 of
Pass the end of the film between the movable member b3 and the fixed member bl in the heat seal cutting device and set it around the fixed member b1, and also pull out the film from the winding body /s of the mechanism A' (1 end of the film is passed through the movable member b/ 2 and fixing member b'
It is set by passing it through the frame and passing it around the fixing member b/I. (Fig. 1) 2)...In the above state, automatic wrapping is repeated to wrap the film around the articles P that are transported one after another on the transport line L, and the film is consumed.
In the illustrated example, when the film on the winding body aI decreases to a certain limit, this is sensed by an appropriate means and feeding of the film is appropriately stopped, and at the same time, the moving member b2 exclusive to the winding body ax is moved to an air cylinder or the like. move forward to press against the fixing member b1, sandwich the ends of the tension film f1 and the wrapping film f2 between both 1) 1 and 1) 2, cut the film f1 side, and cut the film f2. Simultaneously weld (seal) the end and the stretched film on the other side (1 cut end),
Then, the moving member b2 returns to its original position. (Figure 1 → 2
(A) → (B) in the figure) 3)...As described above, the film f2 of the roll a2 and the film t72 of the roll a'2 are connected and stretched vertically, and the article is Used for packaging work.

ある。((...) in Figure 2) 4)...Next, the film is consumed by repeated packaging operations, and this time, a certain amount of weight loss in the roll a2 is sensed, and the supply of the film is stopped. When it is stopped, the moving member b3 dedicated to it moves forward and performs the same action as described above, so that the films fl and f't are connected and stretched vertically, and the film f2 of the reduced-volume roll body a2 is is cut. ((d) in Figure 2) Therefore, remove the reduced roll body a2, roll a new roll body a2 for seven minutes, and then pull out the film f2.
The end is passed between the dedicated moving member b3 and the fixed member bl, and then hung around the fixed member 1)1 to set it and prepare for the next time.

トしておくだけで済む特徴がある。As described above, according to the apparatus of the present invention, the film supply mechanisms provided at the upper and lower sides of the conveyance line are each equipped with a pair of winding bodies, and the films of one of the winding bodies are connected to each other to form the upper and lower stretched films. At the same time, the film on the other roll is set so that it can be automatically connected at any time, so that whenever the film on the roll decreases to a certain limit, the film on the other roll is automatically connected. It is automatically connected to the film in the collection and can supply film completely continuously without any problems for packaging operations.
On the other hand, it has the feature that it is only necessary to replace the reduced roll body with a new roll body and set the film end of the new wind body by wrapping it around the fixing member as described above.

解消し得る、多大の効用を発揮し得る。According to the apparatus of the present invention, the film is automatically and continuously supplied without any interruptions, so unlike the conventional method, the automatic packaging apparatus and its related equipment do not have to be temporarily stopped due to an interruption in the supply of film. It can completely eliminate the problem of having to use it, and it can have great effects.
