Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post-processing apparatus for a deep drawing type packaging machine.

[0002]

2. Description of the Related Art An example of a deep drawing type packaging machine is shown in FIG.
It is like. That is, according to the manufacturing process, the lower film 2 continuously pulled out from the material roll 1 is transported in the horizontal direction. The lower film 2 is vacuum-suctioned in the molding box 3 arranged in the middle of the conveyance, and the concave portion 4 protruding downward is molded. Then, at a predetermined position on the downstream side of the molding box 3, an article to be packaged is automatically or manually supplied into the recess 4.

On the other hand, above the film transport line,
Another material roll 5 is installed, and this material roll 5
, The upper film 6 is continuously drawn out, and the pulled out upper film 6 is superimposed on the lower film 2 at a predetermined position on the downstream side of the supply point of the packaged object.

[0004] Further, a vacuum box 7 is disposed downstream of the polymerization point of the two films 2, 6. The vacuum box 7 sucks and removes the air in the concave portion 4 and seals the two films 2, 6. . Thereby, the article to be packaged is sealed in the recess 4 in a vacuum state. Thereafter, the sealing portions of the two films 2 and 6 are cut in the horizontal and vertical directions by the horizontal cutter device 8 and the vertical cutter device 9 to separately manufacture each vacuum package.

[0005] Endless chains are disposed on both outer edges of the lower film 2 on the transport line, and a number of film holding claws are attached to the endless chains. Then, the film is conveyed in a state where both side edges of the lower film 2 are gripped by the plurality of film holding claws. Then, both side edges 2a and 6a (see FIG. 2) of both films 2 and 6 including the gripped portions become portions not used for the package, and are cut and separated by the vertical cutter device 9. Then, both side edges 2a and 6a of the separated film become scraps formed in one continuous band shape.

Therefore, as shown in FIG. 1, a scrap take-up device 10 having a reel 10a is installed on both side edges on the unloading side of the vacuum packaging machine, and scraps sequentially separated from the reel 10a are removed. I'm trying to take it up.

[0007]

However, the above-described conventional apparatus has the following problems. That is, since the reel 10a has a very large diameter, there is a problem that the entire shape of the scrap winding device 10 is large and the occupied area is large. Further, since one reel roll is wound on the reel 10a, the diameter of the wound scrap becomes large, so that not only is the operation of removing and discarding the reel at the time of disposal processing complicated, but also the volume is large. Become.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and has as its object to solve the above-mentioned problems, to facilitate disposal, and to automatically supply garbage bags and the like. Accordingly, it is an object of the present invention to provide a post-processing device for a deep drawing type packaging machine in which disposal can be performed quickly and easily.

[0009]

In order to achieve the above-mentioned object, a post-processing apparatus for a deep-drawing type packaging machine according to the present invention is provided on a discharge side of a main body of the deep-drawing type packaging machine, A post-processing device for unnecessary film portions on both side edges of a packaging film (upper / lower film) generated in a main body, wherein the film portion continuously discharged in a belt shape is taken out of the main body of the packaging machine. A mechanism for guiding to a predetermined position, a cutter device for cutting a tip of the film portion guided by the guiding mechanism, and a device disposed below the cutter device and capable of collecting chips generated by cutting the film portion. (Claim 1).

As is well known, in a deep-drawing type packaging machine, the packaging film is conveyed while being gripped on both sides by a large number of claws. Is cut off by a vertical cutter device and is not used for the package. Therefore, it becomes an unnecessary film portion and needs to be discarded.

Further, since the film is continuously cut by the vertical cutter device, unnecessary film portions are continuously formed in a belt shape. Therefore, the belt-shaped film portion is guided by a guiding mechanism to a cutter device arranged at a predetermined position ("down" in the embodiment) on the carry-out side of the packaging machine main body. And
In the cutter device, the strip-shaped film portion is cut into small chips by cutting the guided film portion in order from the top.

[0012] The separated chips fall naturally by separating from a series of film portions, and the dropped chips are collected in, for example, a garbage bag.
Thereby, when the chips are filled in the garbage bag, the garbage bag can be removed from the post-processing device and can be directly disposed of. * Definition of terms The "mechanism enabling collection of chips" corresponds to the attachment 37 in the embodiment. That is, by attaching the garbage bag 38 to the attachment 37, the carry-out pipe 3
The chips falling by being guided by 6 can be stored in the garbage bag 38. In other words, those that can be collected by attaching another component are included. Of course, it is of course also possible to provide a container such as a box for receiving chips and to include a member for actually collecting chips.

[0013]

FIG. 3 to FIG. 5 show a preferred embodiment of the present invention. In the present embodiment, since the basic components of the deep drawing type packaging machine are the same as those of the conventional one shown in FIG. 1, illustration and detailed description are omitted. In addition,
The same members as those of the device shown in FIG. 1 are denoted by the same reference numerals.

In this embodiment, the present invention is applied to a vacuum packaging machine, and shows food such as ham as an object to be packaged. A chute conveyor 13 is disposed on the discharge side of the vacuum packaging machine main body 12, and the packages individually cut by the vertical cutter device 9 are moved while sliding on the chute conveyor 13 and are discharged. .

On the other hand, as described in the prior art, both edges of each film separated and cut by the vertical cutter device 9 become scraps 14 continuous in a band shape. The scrap 14 is hung over guide rollers 40 provided at both ends on the unloading side of the vacuum packaging machine main body 12, the traveling direction thereof is changed downward, and the drawing device 18 installed below the unloading side of the vacuum packaging machine main body 12. It is led to.

The drawing device 18 includes a driving roller 20, a driven roller 21, and an urging mechanism 22 for bringing the two rollers 20, 21 into contact with a predetermined pressure. The urging mechanism 22 has an arm 24 rotatably (rotating shaft 23 a) attached to the side wall 23 erected in the vertical direction, and connects a spring 25 between the arm 24 and the side wall 23. By the elastic restoring force of the spring 25, the arm 24 is urged to rotate clockwise in FIG. A driven roller 21 is attached to the tip of the arm 24 (on the opposite side to the spring 25 with respect to the rotation center attached to the side wall 23).

As a result, the driven roller 21 is
With the drive roller 20
At a predetermined pressure. Therefore, when the driving roller 20 rotates, the free driven roller 21
Also rotate. Then, by passing the scrap 14 so as to be sandwiched between the rollers 20 and 21,
As the rollers 20 and 21 rotate, the scrap 14 is pulled out downward.

The driving source of the driving roller 20 is provided from the vacuum packaging machine main body 12 side. That is, the plurality of sprockets 16a to 16c are connected to the driving sprocket 16 on which the chain to which the film holding claws of the vacuum packaging machine body 12 are attached by using the chain 17, and the driving sprocket 16b is driven by one of the sprockets 16b. The roller 20 is attached. Thereby, the scrap 14 is also conveyed in synchronization with the conveyance of the film.

Further, a cutter device 30 is disposed below the drawer device 18, and the cutter device 30 cuts the tip of the scrap 14 to a predetermined size. The cutter device 30 has a rotary blade 31 and a fixed blade 32. The rotary blade 31 has one blade portion 31b extending in the axial direction on a side surface of a rotary body 31a. And
The tip of the blade portion 31b comes into contact with the fixed blade 32.

Thus, each time the rotating body 31a makes one rotation, the blade portion 31b comes into contact with the fixed blade 32, and at that time, the scrap 14 located between the both 31b and 32 is cut. As a result, the tip of the scrap 14 is cut, and small chips 35 are generated and fall.

An unloading pipe 36 is arranged below the cutter device 30, and the unloading pipe 36
The attachment 37 is installed at the lower end. When the opening of the garbage bag 38 is attached to the attachment 37, the chips 35 that have been cut and fallen in the discharge pipe 36 are removed.
Is discharged from the lower end, and naturally falls into the garbage bag 38 and supplied. Therefore, when the garbage bag 38 is detached from the attachment 37, the garbage can be discarded as it is.

The rotating body 31 of the cutter device 30
a is the drive motor 41 via the endless chain 40
The drive motor 4
The output of 1 is also linked to the drive roller 20 of the drawer 18. As a result, when the drive motor 41 rotates, the drive roller 20 rotates in synchronization therewith to pull out the scrap 14, and the rotating body 31a rotates to cut the tip of the scrap 14 between the blade portion 31b and the fixed blade 32. It has become.

Further, the above-mentioned roller 16, drawer device 18, cutter device 30 and mounting tool 37, and their drive mechanisms (drive motor 41 and power transmission mechanism)
As shown in FIGS. 4 and 5, two sets are provided to cut and collect scraps 14 on both side edges in the transport direction.

In the above-described embodiment, a mechanism for cutting and collecting both scraps 14 is provided for each, but the present invention may be only one. That is, for example, it can be dealt with by disposing each roller at an appropriate position and guiding two scraps to one cutter device 30.

In the above-described embodiment, the drive source of the drawer 18 is taken from the vacuum packaging machine main body 12. However, the present invention is not limited to this. It is good.

[0026]

As described above, in the post-processing apparatus for a deep drawing type packaging machine according to the present invention, the scrap produced by separating both side edges of the film is formed into a small chip by cutting the tip. The formed chips fall apart from each other. Therefore, by receiving each of the falling chips in a bag or the like, if a certain amount is accumulated, the chips can be directly disposed of as garbage. That is, there is no need to remove the wound reel and transfer it to the garbage bag as in the related art, and the disposal process is simplified.

[0027] Furthermore, compared to the conventional one, it is cut into small chips, so that it is possible to efficiently fill the bag to be discarded. In other words, the handling does not become complicated due to a large diameter unlike the related art.
