Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip collecting device and a packaging machine using the same.

[0002]

BACKGROUND OF THE INVENTION An example of a deep drawing type packaging machine is shown in FIG.
Some are shown as follows. 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. And
At a predetermined position on the downstream side of the molding box 3, the 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 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, and the work of removing and discarding the reel at the time of disposal processing is not only complicated, but also has a large volume. Become.

Therefore, the inventor of the present invention has made it possible to easily dispose of the waste and automatically supply the waste to a garbage bag.
We have created a post-processing device for deep drawing type packaging machines that enables quick and easy disposal. To briefly explain the invention invented earlier, this post-processing device is provided on the carry-out side of the deep drawing type packaging machine main body, and unnecessary film portions (scraps) on both side edges of the film generated by the packaging machine main body are provided. ) Is sequentially cut from the tip by a cutter device to generate chips.
Then, since the generated chips naturally fall in the carry-out pipe, a dust bag is attached to the lower end of the carry-out pipe so that the chips are stored in the dust bag. Therefore, by removing the garbage bag from the discharge pipe, the stored chips can be discarded.

With the above-mentioned apparatus, disposal can be performed quickly and easily, which is very convenient. But,
When the experiment was repeated in various cases, the chips remained in the discharge tube, and the chips were not supplied in the garbage bag, or the chips stuck in the middle of the garbage bag, and it was enough to store it in the garbage bag. It may not be possible.
Furthermore, the garbage bags are stuck together and do not spread neatly, so that chips may not be stored in the garbage bags.

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 and to easily set a bag in a housing to an inflated state.
It is an object of the present invention to provide a chip collecting device capable of reliably storing chips from which scraps have been cut in a bag, and a packaging machine using the same.

[0011]

In order to achieve the above-mentioned object, in a chip collecting apparatus according to the present invention, chips formed by cutting a strip-shaped scrap separated from a film material discharged from a packaging machine are provided. A chip collecting device for storing a chip for storing the chip, having a housing with an upper opening capable of storing a bag for storing the chip, and a connection port for directly or indirectly connecting the housing to the suction device. And the pressure in the housing is reduced by discharging the air in the housing to the outside through the connection port (claim 1). In the embodiment, the installation position of the connection port in the housing is below the side surface, but is not limited thereto, may be above the side surface, may be the bottom surface, or may be the lid, and may be the inside of the housing. Can be installed at any position where the pressure can be reduced.

Further, in the packaging machine according to the present invention, the packaging machine body for wrapping an object to be packaged with a film material and sealing or cutting a predetermined position of the film material to produce individual packaging bodies, A cutting means for forming a chip by cutting a band-shaped scrap separated from the film material discharged from the packaging machine main body; and a bag attached below the cutting means for receiving the chip generated by the cutting means. And a tip collecting device according to any one of claims 1 to 4 for storing the bag (claim 5).

As is well known, in a deep drawing type packaging machine, a film material is conveyed while being gripped on both side edges 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.

In a pillow wrapping machine, the outside of the center seal portion is cut so that the center film portion is aligned or both side edges of the film material are aligned. This allows
The outside of the center seal is separated from the film material,
Unnecessary film portions (scraps) in a continuous band form.

As described above, in various packaging machines (not limited to the above-described deep-drawing type and pillow), unnecessary film materials (scraps) separated into strips in the manufacturing process are generated. Therefore, a chip is generated by cutting the unnecessary film material (scrap) from the beginning. This chip falls naturally by its own weight.

The chip collecting device of the present invention is for collecting the chips formed as described above directly into a bag (garbage bag). That is, the suction device is directly or indirectly connected to the connection port (corresponding to “the exhaust pipe 53” or “the opening of the exhaust pipe 53” in the embodiment) of the housing. Here, "indirectly" means to connect to the suction device via another member such as a hose as in the embodiment.

Then, a bag for collecting the above chips is stored in the housing of the present invention. At this time, since the upper part of the housing is open, the upper part of the bag can protrude out of the housing through the opening, and can receive the falling chips. In order to reduce the pressure inside the housing as described later, the opening area of the housing is preferably as small as possible.

Usually, bags are sold in a closed state,
It is stored and must be opened for use. Therefore, the suction device is operated to reduce the pressure inside the housing. Then, the bag expands in the housing, and the chip can be stored. In other words, when trying to inflate the bound bag manually, the bag may be tightly closed due to static electricity or the like, which is complicated, but in the present invention, it is simple and easy by reducing the pressure inside the housing. Can be greatly expanded.

When the bag is spread in this manner, the chips that fall are more likely to collect at the bottom of the bag, so that more chips can be reliably collected. When the chips are fully stored in the bag, the bag can be removed and disposed as it is.

[0020] Preferably, the bag is in close contact with the inner surface of the housing including the connection port, and a blocking mechanism (in the embodiment, a partition bottom plate having a double bottom structure in the embodiment). 55 "or" shielding plate 56 "). The deterring mechanism is provided with, for example, a partition plate having a through hole having substantially the same shape as the wall surface inside a predetermined wall surface of the housing, and a space formed between the partition plate and the predetermined wall surface. The connection port may be located at a position (claim 3). Here, the wall surface means a side surface as well as a bottom surface and a lid (top surface).

By reducing the pressure inside the housing, the bag spreads almost instantaneously. Then, the bag once expanded does not return to the original flat closed state even if the suction by the suction device is stopped and the reduced pressure state in the housing is released.
However, the degree of swelling may be reduced to a small degree. Therefore, it is preferable to maintain the decompressed state. At this time, if the expanded bag closes the connection port, the air inside the housing cannot be removed, and the upper part of the housing is convenient for inserting the bag. Since it is open at the top, the decompression state drops,
It may return to normal pressure. Therefore, by providing a suppression mechanism, the bag is prevented from closing the connection port.

Further, the bag may be provided with a hole at a lower portion thereof. In this way, if a bag provided with a hole is used, when the suction device is further operated even after the bag is spread by the suction device,
The air inside the bag creates a flow of air that is drawn out of the bag through the holes. Therefore, the chips are likely to collect at the bottom of the bag by being guided by the flow, and adhere to the inner surface above the bag, and further, the chips that try to adhere to the packaging machine side above the bag, The air flow can force the air into the chip. Further, since the chips stored in the bag are pressed downward by the flow of air, more chips can be stored. At this time, it is preferable to provide a restraining mechanism as in claims 2 and 3 because the flow of the air can be secured.

[0023]

3 to 7 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 a food to be packaged such as ham. A chute conveyor 13 is arranged on the discharge side of the vacuum packaging machine main body 12, and the packages finally cut individually by the vertical cutter device 9 move while sliding on the chute conveyor 13 and are discharged. .

On the other hand, as described in the prior art, both side edges of each film separated and cut by the vertical cutter device 9 become scraps 14 which are continuous in a belt shape. The scrap 14 is wrapped around guide rollers 40 provided at both ends on the discharge side of the vacuum packaging machine main body 12, the traveling direction thereof is changed downward, and the drawing device 18 installed below the discharge 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 also
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 drawn downward.

The driving source of the driving roller 20 is given from the vacuum packaging machine main body 12 side. That is, a plurality of sprockets 16a to 16c are connected to the driving sprocket 16 on the chain of the vacuum packaging machine main body 12 to which the film holding claws 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, and 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.

Under the cutter device 30, a discharge pipe 36 is arranged, and the discharge pipe 36 is disposed.
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 removed from the attachment 37, the garbage can be directly discarded as garbage.

The rotating body 31 of the cutter device 30
a is a drive motor 42 via an endless chain 41
The drive motor 4
The output 2 is also linked to the drive roller 20 of the drawer 18. As a result, when the drive motor 42 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, mounting tool 37, and their drive mechanisms (drive motor 42 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 provided for 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, but the present invention is not limited to this, and an independent drive motor prepared separately is used as a power source. It is good.

Here, in the present invention, a chip collecting device 50 for efficiently and smoothly storing chips in the garbage bag 38 is provided. This chip collecting device 50
Is a housing 5 having an upper opening capable of storing a garbage bag 38 therein.
1 and a cover 51 is provided on an upper surface of the housing 51.
And the opening area of the opening 51a is made as small as possible. That is, the garbage bag 38 attached to the discharge pipe 36 is stored in the housing 51 with the opening / closing lid 52 opened.

A circular through hole (connection port) is provided below the side surface of the housing 51, and an exhaust pipe 53 is connected to the periphery of the through hole. Thereby, the inside and the outside of the housing 51 communicate with each other through the exhaust pipe 53, so that air can flow. One end of a hose 54 is attached to the exhaust pipe 53, and the other end of the hose 54 is connected to a suction blower (not shown).
Therefore, when the suction blower is operated, the air in the housing 51 is removed by suction, and the pressure in the housing 51 is reduced.

The housing 51 has a double bottom.
A partition bottom plate 55 is provided at a position one step higher than the bottom plate 51 b of the housing 51, and the partition bottom plate 55 has a plurality of through holes 5.
5a is provided. The space above and below the partition bottom plate 55 in the housing communicates with the through hole 55a. Therefore, when the suction blower is operated as described above, the housing 51
The air existing in the upper space reaches the lower space through the through hole 55 a of the partition bottom plate 55, and is further suctioned and removed to the outside of the housing 51 through the exhaust pipe 53. That is, the housing 5
The inside of 1 is in a decompressed state.

Further, in the present embodiment, as shown in FIG.
Is formed. The size of the opening of the hole 38a is smaller than the size of the chip 35 so that the chip 35 stored in the garbage bag 38 is not discharged to the outside through the hole 38a. There is a need.

With the above configuration, even if the garbage bag 38 does not spread closely due to, for example, static electricity, the suction blower is operated with the garbage bag 38 inserted and arranged in the housing 51. Then, the inside of the housing 51 is decompressed, so that the garbage bag 38 expands, and the chip 35 can be stored inside. The reason that the garbage bag 38 spreads like this is
This is performed regardless of the presence or absence of the hole 38a.

In this embodiment, the hole 38 is formed in the garbage bag 38.
Since air is sucked by the suction blower described above, the air in the garbage bag 38 is guided to the outside of the garbage bag 38 from the hole 38a provided thereunder. It is discharged to the outside of the casing 51 by taking the same route as that described above. Therefore, the refuse bag 38 has a flow of air flowing downward from the upper opening (the hole 38a).

As a result, the chip 35 is actually put in the garbage bag 38.
When chips are attached to the inside of the discharge pipe 36 or the upper part of the garbage bag 38 due to static electricity or other factors when they are dropped and supplied and stored therein, even if there is a chip that does not fall by itself any more, it will follow the flow of air. The garbage bags 38 can be sequentially stacked from the bottom side. In addition, the chip is strongly pressed down by the flow of air, so that the chip 35
Can be efficiently collected.

Then, a predetermined amount of chips 3 is placed in the garbage bag 38.
When 5 has been collected, open and close the lid 52,
The garbage bag 38 is removed from the discharge pipe 36 and taken out of the housing 51 to the outside. Thus, the chip 35 can be discarded by discarding the garbage bag 38 as it is.

In order to ensure the flow of air from the inside of the garbage bag 38 to the outside of the garbage bag 38 via the hole 38a, the air flowing out of the garbage bag 38 must be surely exhausted. It is necessary to exhaust air from 53 to the outside of the housing 51 via the hose 54. Therefore, in the present embodiment, the partition bottom plate 55
Is provided, and a lower space in the housing 51 in which the exhaust pipe 53 is opened is separated from an upper space in the housing 51 in which the garbage bag 38 is present. There is no possibility of blocking the portion, that is, the through hole provided below the side surface of the housing 51, to prevent the outflow of air. Therefore,
Since the air exhaust path is secured, the chips can be strongly pressed down in the garbage bag 38 by receiving the air flow as described above.

Since the opening of the exhaust pipe 53 need not be closed, it is not always necessary to form the double bottom as described above. For example, as shown in FIGS. A shielding plate 56 is provided on the bottom surface 51 b of the housing 51 at a predetermined distance in front of the suction port), and the garbage bag 38 enters between the shielding plate 56 and the opening of the exhaust pipe 53, and the exhaust pipe 53
May not be blocked.

In this case, for example, the flow of air passes through a gap between the side of the shielding plate 56 and the side wall of the housing 51 as shown by an arrow A in the drawing, or the through-hole 56a is formed in the shielding plate 56.
And a route through the through hole 56a (arrow B in the figure)
Etc. Of course, in other configurations,
As long as the garbage bag 38 does not close the opening of the exhaust pipe 53, various kinds of things can be taken.

In the above embodiment, the garbage bag 3
Although the hole 38a is provided in 8, the present invention is not limited to this, and the hole 38a may not be necessarily provided. That is, for example, when the material of the film as the packaging material is relatively hard or the film thickness is large, the chips are naturally stored in the garbage bag 38 by natural fall due to their own weight. In such a case, in particular, the hole 38
By providing a, it is not necessary to forcibly secure the flow of air.

Therefore, as in the above-described embodiments and modifications, a suppression mechanism (partition bottom plate 55, shielding plate 56, etc.) for preventing the dust bag 38 from closing the opening of the exhaust pipe 53 is provided. It is not necessary to provide. In other words, prior to the start of use, it is sufficient that the inside of the housing 51 can be decompressed by suction with a suction blower so that the garbage bag 38 can be inflated.

In each of the above-described examples, the case 51
Although a through hole serving as a connection port is provided below the side surface of the present invention, the present invention is not limited to this, and may be provided above the side surface, or may be provided on the bottom surface 51 b or the opening / closing lid 52. In accordance with the change of the position where the connection opening is provided, the partition bottom plate is replaced with the partition bottom plate, and the partition plate is erected along the side surface, and the partition plate is arranged under the opening / closing lid, or the connection opening (through hole) is shielded. Various measures can be taken, such as arranging boards. Of course, in consideration of the flow of air, it is preferable to adopt a double bottom structure in which air flows from top to bottom in the garbage bag 38 and is discharged to the outside via the partition bottom plate as it is.

In each of the above-described examples, the case where the present invention is applied to scrap processing in a deep drawing type packaging machine has been described. However, the present invention is not limited to this. There is a case where the scrap is generated by cutting the outside of the part into a band shape, but in such a case, the present invention is also used, and a chip is generated by sequentially cutting from the tip of the scrap, and the generated chip is described above as a chip. You may collect | recover with a collection device. And it can be suitably used for other packaging machines.

[0051]

As described above, in the chip collecting apparatus and the packaging machine using the same according to the present invention, the inside of the housing can be depressurized by exhausting the air in the housing by the suction device. Can be easily and greatly expanded by reducing the pressure. Therefore, initial setting such as mounting of a bag can be easily performed, and chips can be stored in the spread bag.

In particular, when configured as in claims 2 and 3,
Even after the bag is spread, the inside of the housing can be kept in a reduced pressure state. When a bag having a hole is used as described in claim 4, by operating the suction device, an air flow is formed in which air in the bag is led to the outside through the hole. . Therefore, the chips can be reliably guided to the lower side of the bag according to the flow of the air, and the chips are pushed downward, so that more chips can be stored.

Moreover, the film thickness is relatively thin,
In the case of a chip made of a soft film material, the chip adheres to the upper part of the bag or the peripheral surface of the packaging machine before reaching the bag due to static electricity or the like, and it is difficult to efficiently store the chip in the bag. However, by forcibly guiding the chips to the bottom of the film by the flow of air as described above, the chips can be reliably stored.
