Description

[Detailed description of the invention] The present invention is based on a deep-drawing automatic packaging device that continuously wraps products using, for example, a long strip-shaped film. ) Excess film (slit waste) on both sides of the film
By continuing to cut the film into short strips, it is possible to easily handle the surplus film afterwards, eliminate the need for space in the workplace due to the surplus film, ensure safety and smoothness of work, and significantly improve work efficiency. It is intended to obtain.

In conventional deep-drawing automatic packaging equipment, the long excess film (slit waste) on both sides of the lower film that is generated when the container is completed is either stuffed into a waste bag or the like as it is, or is removed as appropriate. It was rolled up into small pieces and discarded.

Therefore, in the above case, the excess film not only becomes bulky and causes various damage to the subsequent handling of the film, such as transportation, but also takes up space in the workshop and obstructs the work, making it difficult to wrap the packaging work. There were drawbacks that caused various problems.

The present invention completely eliminates the above-mentioned drawbacks, makes it less bulky, facilitates the subsequent processing of surplus film, and saves space in the workplace, thereby making packaging work safer and smoother. Moreover, it is designed to be able to be carried out with high efficiency.

An embodiment shown in the accompanying drawings will be described in detail below.

Reference numeral 1 denotes a belt-shaped lower film; 2 denotes a well-known film transporting device that intermittently transports the lower film 1 by clamping it with a plurality of clamping claws 3 attached to both longitudinally opposite edges of the lower film 1; The clamping claws 3 are connected to the container completed section (to be described later), that is, between each packaging container in a parallel state (in three rows in this embodiment) after packaging the packaged products and the clamping part. After passing through a vertical cutter device (slitter) that slits both side edges of the lower film 1 held by the claws 3 along the film traveling direction to form individual finished containers, the lower film 1 is held by the claws 3... It's like releasing.

4 is an upper film for covering, 5 is an article to be packaged, 6 is a film cutting device, 6' is a filling section for articles to be packaged, 7 is a horizontal cutter device, and 8 is a vertical cutter device, such as a well-known slitter. used.

9 is a vacuum sealing device, 10 is a chute, and 10' is a guide roller.

11.11 is the machine frame 1 in the vertical cutter device 8 section.
A long surplus film (slit waste) 13. which is slit by the vertical cutter device 8 is driven by an appropriate drive means (not shown) using a surplus film discharge roller provided at 2.
13.

A roller 14.14 is provided elastically to the surplus film discharge rollers 11, 11, and serves to pinch and discharge the surplus film 13.13 together with the surplus film discharge rollers 11, 11.

Reference numeral 15 denotes a long surplus film 13 that is continuously discharged by the surplus film discharge rollers 11, 11.
．． 13 into short strip-shaped prefectures 16, an excess film cutting device is installed on one side of the vertical cutter device 8, and a rotating shaft supported on the machine frame 17 as shown in Figures 3 and 4 is used. A pair of surplus film guide rollers 20 and 20' are attached to 18 and 18' so as to be slidable in the axial direction through keys 19 and 19', respectively, and both sides of one surplus film guide roller 20' are connected to the other. The surplus film guide roller 20 is fitted between the flanges 21 and 21' on both sides of the surplus film guide roller 20.
A protruding strip 23 formed on the center circumference of the surplus film guide roller 20 is fitted into a fitting groove 22 formed on the center circumference of the excess film guide roller 20.

24 is a surplus film guide plate provided in front of the surplus film guide roller 20, and is for guiding the surplus film 13.13 from the vertical cutter device 8 section to the surplus film guide roller 20.20'. , the female screw portions 27 are screwed into the sliding male screw rods 26 attached to the machine frame 17 in such a manner that both side wall portions 25° and 25' sandwich both side portions of the surplus film guide roller 20'. It is something.

28.28' is the surplus film guide roller 20.2
A pair of rotary cutters and a fixed cutter are provided in parallel to the axial direction at the bottom of 0'.

29 is a waste storage container detachably attached to the lower part of the rotary cutter 28 and fixed cutter 28'; 30 is the machine frame 1;
A guide roller 30' attached to 7 is a bundle.

The surplus film guide rollers 20, 20', the rotary cutter 28, and the fixed cutter 28' are rotated by gears 32, 33, 34, 35 from a rotating shaft 31 rotated by a motor (not shown) as shown in the fourth figure. ,36.37
Although the rotation is carried out by means of a rotation means (not shown), it may be carried out by other suitable rotation means (not shown).

Since the present invention has the above-described configuration, the long excess film (slit waste) 13.
11, the excess film is discharged out of the deep drawing packaging machine, and further fed between the surplus film guide rollers 20 and 20' of the surplus film cutting device 15 disposed on one side of the deep drawing packaging machine, and the surplus film guide roller 20,
The government offices 16 are cut into short pieces by a rotary cutter 28 and a fixed cutter 28' located at the lower part of the government office 20', and the government offices 16 are dropped and stored in a government office storage container 29 below.

In this case, the surplus film guide rollers 20 and 20' in the surplus film cutting device 15 separate the two surplus films by dividing the body into two by the convex strip 23 at the center of the body as shown in FIG. 13.13 can be fed without polymerizing during transport, and the position (surplus film feeding position) relative to the rotary cutter 28 and fixed cutter 28' can be adjusted appropriately using the sliding male threaded rod 26. A surplus film guide plate 24 is provided on the front surface of the surplus film guide roller 20 and moves together with the surplus film guide rollers 20 and 20' to move the surplus film selectively by rotating. 13.13 can be easily introduced.

According to the present invention, when cutting long surplus films (slit waste) generated separately from both sides of an automatic packaging machine into short strips, a cutting device disposed on one side of the packaging machine is used. The two surplus films are mutually superposed between the rotary cutter and the fixed cutter by a pair of surplus film guide rollers in which the body is divided into two by flanges on both sides and a convex strip on the circumference of the central body. Since the film is introduced in a parallel manner and cut into strips, it is possible to guide and cut the excess film that is discharged separately from both sides of the packaging device into a single cutting device. This simplifies the equipment, reduces the economic burden, and does not put an unreasonable burden on the cutter during cutting, so the cutter's sharpness and lifespan can be extended, allowing cutting to be performed with high efficiency. Moreover, since it is possible to eliminate the need to take up space in the workplace due to surplus film, the work can be carried out safely, smoothly, and with high efficiency.

In this example, the automatic packaging device is described as a deep-drawing automatic packaging device, but it is not limited to this, and this can be used for all automatic packaging devices that produce long, narrow surplus films. It is something that can be done.
