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 respectively arranged on both outer edges of the transport line of the lower film 2, 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 the scraps sequentially separated from the reel 10a are removed. I'm trying to take it up.

However, in the above-mentioned conventional device,
There were the following problems. That is, the reel 10a has a very large diameter, and the scrap winding device 1
However, there is a problem that the overall shape of 0 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.

In order to solve such a problem, the present applicant has previously proposed a post-processing apparatus for a deep drawing type packaging machine in Japanese Patent Application Laid-Open No. 2000-302108. The invention according to the prior application is provided on the carry-out side of a deep drawing type vacuum packaging machine main body, and guides unnecessary film portions (scraps) on both side edges of a film generated by the vacuum packaging machine main body to a drawing device by rollers. The drawing device draws scraps that are continuous in a band shape and rotates the scraps while holding the scraps from both sides by a driving roller and a driven roller, and supplies the scraps to the cutter device. Then, the tip of the scrap was sequentially cut by a cutter device to generate chips 35, and the generated chips were collected in a garbage bag attached to the lower end thereof via a discharge pipe. Therefore, by removing the garbage bag from the discharge pipe, the stored chips can be discarded.

[0009]

The invention according to the prior application is very convenient because an unnecessary film portion can be cut by a small device and can be collected in a garbage bag as it is. However, with the recent ecology boom,
The film used for packaging also becomes PVC-free, and a soft film material may be used. In this case, the unnecessary film portions on both side edges of the film cannot be smoothly guided to the cutter device simply by being carried out by the rollers, and as a result, there is a possibility that the film cannot be cut into a predetermined size and clean.

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 processing, and to eliminate unnecessary film portions regardless of film material. An object of the present invention is to provide a post-processing device for a deep drawing type packaging machine which can be smoothly supplied to a cutter device to perform a cutting process.

[0011]

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, This is a post-processing device for unnecessary film portions on both side edges of a packaging film (upper / lower film) generated in a main body, and has both ends opened at one end near the carry-out side of the packaging machine main body. A guide cylinder, gas injection means for injecting gas from one end of the guide cylinder toward the inside,
And a cutter device disposed near the other end of the guide cylinder, wherein the film portion is guided through the guide cylinder to the cutter device. Note that the gas injected by the gas injection cutoff is air in the embodiment, but an inert gas or other various gases can be used.

As is well known, in a deep drawing type packaging machine, both sides of the packaging film are conveyed while being gripped by a large number of claws, and both sides of the packaging film are eventually 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. Then, since the film portion is continuous, it is gradually carried out of the packaging machine body as the packaging process proceeds.

Therefore, in the present invention, the unloaded film portion is supplied into the guide cylinder from the opening at one end of the guide cylinder. At this time, the gas injection means is arranged on one end side of the guide cylinder, and gas is injected toward the guide cylinder, so that the injected gas flows through the guide cylinder and the other end. Is discharged from Therefore, the film portion smoothly moves in the guide cylinder along with the flow of the gas, and is guided to the outside, that is, the cutter device from the other end. Then, in the cutter device, the strip-shaped film portion is cut into small chips by sequentially cutting the guided film portion from the top.

[0015] Preferably, the guide cylinder is formed to be narrower on the other end side than on the one end. With this configuration, it is easy to supply the film portion into the guide cylinder, and since the leading end of the film portion moving in the guide cylinder is discharged from the other end of the narrowed guide cylinder, it is directed toward the cutter device. Can be carried out. Needless to say, the guide cylinder may have the same shape at both ends, and may have any shape, for example, the opening at the other end may be widened or narrowed immediately before.

On the other hand, it is preferable that an opening portion at one end of the guide cylinder is inclined at a predetermined angle with respect to the unloading direction of the packaging machine body. It is more preferable that a guide member for guiding the film portion into the guide cylinder is disposed on the one end side of the guide cylinder. By doing so, the film portion is smoothly supplied into the guide cylinder. Note that the guide member may be formed integrally with the guide cylinder, or may be formed as a separate member. Further, in the case of forming with a separate member, in the embodiment, it is directly attached to the guide cylinder, but it may be indirectly attached or may not be attached. In other words, one end is
It does not necessarily need to be connected to the guide cylinder, it specifies the arrangement position, and by supporting it on another machine frame, it is possible to arrange the guide member separately from the guide cylinder. is there.

Further, it is preferable that a pair of conveying rollers for sandwiching the film portion and feeding the film toward the guide cylinder are provided on the discharge side of the packaging machine main body. With this configuration, the film portion can be forcibly sent out by the conveyance force of the conveyance roller and supplied into the guide cylinder. Then, since the film portion continues to receive the conveying force from the conveying roller, the film portion supplied into the guide cylinder has the conveying force from the conveying roller and the flow of the gas injected from the gas injection unit. Both actions lead to a more reliable guide to the cutter device.

[0018]

FIG. 3 to FIG. 5 show a first 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. 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 is used for food such as ham as an article to be packaged. A chute conveyor 13 is disposed on the unloading side of the vacuum packaging machine main body 12, and the packages individually cut by the vertical cutter device 9 are individually cut by the chute conveyor 13.
It moves while sliding on the top and is carried out. On the other hand, as described in the prior art, both side edges of each of the films separated and cut by the vertical cutter device 9 are strip-shaped continuous scraps 1.
It becomes 4.

The post-processing apparatus for a deep drawing type packaging machine according to the present invention is installed on the discharge side of the vacuum packaging machine main body 12, and
First, a guide cylinder 20 is provided upright on the carry-out side. This guide cylinder 20 has both ends opened,
One end 20a located above is located near the discharge side of the vacuum packaging machine main body 12, more specifically, close to the discharge position of the scrap 14 cut and separated by the vertical cutter device 9 from the vacuum packaging machine main body 12. To place. Furthermore, in this embodiment,
The opening portion of the one end 20a is an inclined surface so as to intersect at a predetermined angle with respect to the unloading direction of the vacuum packaging machine body 12 (scrap 14). As a result, even if the tip of the scrap 14 moves in the horizontal direction, the tip of the scrap 14 abuts on the inner wall surface of the guide cylinder 20 and its course is changed. At this time, because the gravity is applied, even if it moves horizontally, its tip is descending,
The course is changed downward and moves down along the guide cylinder 20.

Further, a flat guide member 22 is attached so as to cover a part of the opening of one end 20a of the guide cylinder 20. Therefore, even if the scrap 14 hits the inner wall surface of the guide cylinder 20 and its course is directed upward, it hits the guide member 22 and the course is directed downward. Therefore, in any case, the tip of the scrap 14 surely advances toward the inside of the guide cylinder 20, that is, downward.

Further, in this embodiment, as shown in FIG. 5, the guide member 22 has a circular through hole 22a. Then, the guide member 22, more specifically, the through hole 22
The injection nozzle 24 is arranged above “a”. The injection nozzle 24 is configured such that the injection port faces downward and air is injected from the injection port. Although not shown, the other end (upper side in the figure) of the injection nozzle 24 is linked to a compressor, a pump, a cylinder, and other devices capable of injecting various types of air.

The air injected from the injection nozzle 24 flows into the guide cylinder 20 through the through hole 22a of the guide member 22. Thereby, the guide cylinder 2
The air that has flowed into the space 0 moves downward as it is, and is discharged to the outside from the opened other end 20b. Therefore, the scrap 14 supplied into the guide cylinder 20 is reliably moved below the guide cylinder 20 (the other end 2) by riding the air flow.
0b) and is discharged to the outside (downward) as it is.

Although the injection nozzle 24 is shown above the guide member 22 in the illustrated example, it may be attached to the guide member 22. That is, the through hole 22
a is a mounting hole for the injection nozzle 24. In this case,
The guide member 22 functions only as a mere support member of the injection nozzle 24, and may not have the guide function of suppressing the upward movement of the scrap 14 described above.

Further, in the present embodiment, the injection nozzle 24 is not positioned at the center of the guide cylinder 20 but is positioned at the vacuum packaging machine main body 12.
Eccentric in the direction away from the viewer. With this configuration, the path of the scrap 14 is surely lowered by the air injected from the injection nozzle 24 in a state where the tip of the scrap 14 is located to a certain extent above the guide cylinder 20, that is, the inside of the guide cylinder 20. Turned to in this way,
The air injected from the injection nozzle 24 is the guide cylinder 2
The function of smoothly guiding the scrap 14 within the cylinder 0 to the other lower end 20 b and the scrap 14 carried out from the vacuum packaging machine main body 12 are guided to the inside of the guide cylinder 20. Of course, the injection nozzle 24 may be at the center of the guide cylinder 20 or may be eccentric toward the vacuum packaging machine body 12.

The guide cylinder 20 has a truncated cone shape whose diameter decreases as it goes downward.
The opening at 0b is smaller than the opening at one end 20a. Therefore, the air that moves downward in the guide cylinder 20 also moves toward the narrowed other end 20b. Therefore, the structure in which the tip of the guide cylinder 20 is tapered and the flow of air work synergistically, and the scrap 14 is smoothly guided to the opening of the other end 20b of the narrow guide cylinder 20, and positioned. It is carried out.

On the other hand, a cutter device 30 is arranged below the guide cylinder 20, 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, and the rotary blade 31 has one blade portion 31b extending in the axial direction on a side surface of a rotary body 31a. 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.

Further, in the present embodiment, a discharge pipe 36 is disposed below the cutter device 30, and a fitting 37 is provided at a lower end of the discharge pipe 36. Therefore, when the opening of the garbage bag 38 is attached to the attachment 37, the chip 35 cut and dropped in the discharge pipe 36 is discharged from the lower end thereof and naturally falls into the garbage bag 38 as it is. 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
Of the drive shaft. Thereby, the drive motor 4
When the rotating member 1 rotates, the rotating body 31a rotates and the blade portion 31b,
The tip of the scrap 14 is cut between the fixed blades 32.

Further, the above-mentioned guide cylinder 20, guide member 22, injection nozzle 24, cutter device 30 and mounting tool 37, and their driving mechanisms (drive motor 41 and power transmission mechanism) are shown in FIGS. As shown, two sets are provided, and the scraps 14 on both side edges in the transport direction are cut and
I try to collect.

FIG. 6 shows a second embodiment of the present invention. In the present embodiment, based on the first embodiment described above, a pair of transport rollers 45 are respectively provided on the unloading side of the vacuum packaging machine body 12, more specifically, on the unloading side of each scrap 14. , 46 are arranged. The transport rollers 45, 46 sandwich the scrap 14, which is a film portion, from above and below, and feed the scrap 14 toward the guide cylinder 20, one of which is a drive roller 45 linked to a drive motor, and the other of which freely rotates. Driven roller 4

As described above, the scrap 14 is sandwiched between the transport rollers 45 and 46 and is forcibly fed out, so that the scrap 14 is surely supplied into the guide cylinder 20 located forward in the traveling direction. Note that the other configuration and operation and effect are the same as those of the above-described first embodiment.

The power source for the driving roller 45 can be obtained from the vacuum packaging machine main body 12, or an independent driving motor prepared separately can be used. In any case, it is necessary to synchronize with the conveyance (speed and timing of intermittent driving) of the film in the vacuum packaging machine main body 12.

[0035]

As described above, in the post-processing apparatus for a deep drawing type packaging machine according to the present invention, a guide cylinder having both ends opened on the discharge side of the packaging machine body, and gas is supplied into the guide cylinder. Since the gas injection means is provided, even if it is a soft film material, it can be reliably guided outside through the guide cylinder. Therefore, regardless of the material of the film,
