Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-line type pouch manufacturing apparatus, and more particularly to an in-line type pouch manufacturing apparatus for manufacturing a pouch in a chamfered state.

[0002]

2. Description of the Related Art A pouch made of a resin sheet or the like for packaging contents such as food has been used. The pouch has a substantially rectangular flat shape when the contents are not enclosed and is not inflated, and the portions corresponding to the corners are chamfered.

An apparatus used for manufacturing a pouch includes a heat seal portion, a pouch material cutting blade, a pouch material introducing means,
With a punch. In the production of the pouch, first, a strip-shaped sheet that is the front surface of the plurality of pouches and a strip-shaped sheet that is the back surface of the plurality of pouches are partially fused by the heat-sealing portion to form the pouch. The material is manufactured.
Next, the pouch material is conveyed to the position of the punch by the pouch material introducing means, and as shown in FIG. 6, the punch cuts 105a, 105a at the position corresponding to the corner of the pouch.
Can be inserted. Then, the pouch material cutting blade cuts the pouch material 105 as shown by the broken line in FIG. 6 so as to connect the ends 105b and 105b of the cut 105a with each other to manufacture one pouch.

[0004]

However, in the conventional in-line type pouch manufacturing apparatus, as described above, the tips 105b, 105b of the notches 105a, 105a by the punch are used.
Since the pouch material 105 was cut by tying it, when the cutting position was shifted, two 105A and 105A were generated as shown in FIG. Since it is unfavorable as a product that the 105A is generated in the pouch, the cutting for removing the 105A portion must be separately performed by the pouch material cutting blade, and it is necessary to perform the cutting twice in total. Therefore, the manufacturing process becomes complicated, and it is difficult to reduce the price of the pouch material. Further, since the part 105A is cut and discarded, there is much waste of material for manufacturing the pouch, and it is difficult to cope with environmental problems.

In order to prevent the two 105A from occurring even when the cutting position is slightly deviated, for example, a pouch material having a large blade thickness that can be cut with a considerable width in the longitudinal direction of the band-shaped pouch material. It is conceivable to use a cutting blade. However, even in this case, the amount of the portion that is cut and discarded is as large as that of the conventional in-line pouch manufacturing apparatus described above.

Therefore, an object of the present invention is to provide an in-line type pouch manufacturing apparatus which does not cause a crack, has a simple manufacturing process, and has little waste of materials for manufacturing the pouch.

The pouch manufactured by the in-line type pouch manufacturing apparatus 1 is a type configured by fusing two substantially rectangular sheets 3 and 4 having a front surface and a back surface with each other around their peripheries.

As shown in FIG. 1, the sheets 3 and 4 which are the front and back surfaces of a plurality of pouches are wound in a roll shape, respectively, and the sheet introducing means 11 has two sheets arranged to face each other. It is equipped with rollers 11A and 11B.
The two rollers 11A and 11B are arranged apart from each other, and the other roller 1 facing the one roller 11B.
The sheet 3 as the front surface comes into surface contact with the peripheral surface of 1A, and the sheet 4 as the back surface comes into surface contact with the peripheral surface of one roller 11B facing the other roller 11A. By rotating the two rollers 11A and 11B, the two sheets 3 and 4 are formed into a planar shape, and the two sheets are overlapped to form a strip shape and introduced into the heat seal portion 12.

The heat-sealing portion 12 is configured to heat-seal both side surfaces of the two belt-shaped sheets 3 and 4, that is, the two edges. Further, it is configured such that heat sealing is performed with a predetermined width from one edge portion to the other edge portion in the width direction of the strip-shaped sheets 3 and 4.
In this way, the pouch material 5 is manufactured by being partially heat-sealed by the heat-sealing portion 12.

The pouch material introducing means 13 comprises two rollers 13A and 13B which are arranged to face each other. Two
One roller 13A, 13B has a pouch material 5 between them.
When the pouch material 5 does not exist, the pouch material 5 has a positional relationship in which the pouch material 5 is sent to the pouch material cutting blade 14 as the rollers 13A and 13B rotate while being sandwiched between the two rollers 13A and 13B. Is configured. The pouch material introducing means 13 has a first driving means 17

In the timing belt, the rib portions are made of rubber, and the portions other than the ribs are made of rubber having a plurality of core wires oriented in the longitudinal direction of the belt uniformly inside. The inner side 15C of the timing belt 15A provided with the rib 15B is the rib 1
The atmospheric pressure is lower than that of the outside 15D where 5B is not provided, and it is a so-called vacuum belt. Therefore, when the pouch material 5 is placed on the outer side 15D, the pouch material 5 is attracted to the through hole 15a. This can prevent the pouch material 5 from freely moving on the timing belt 15A. Further, since the timing belt 15A is used, it is possible to improve the feeding accuracy when the pouch material 5 placed on the belt is conveyed.

The timing belt 15A includes a roller 15E provided on the upstream side in the moving direction of the pouch material 5,
It is stretched between the roller 15F provided on the downstream side. The pouch material feeding belt 15 includes rollers 15E,

The longitudinal direction of each timing belt 15A corresponds to the moving direction of the pouch material, and as shown in FIG. 3, these groups are arranged in parallel at the same position in the moving direction of the pouch material. There is. Roller 15 provided on the upstream side
E (FIG. 1) is located immediately downstream of the pouch material cutting blade 14. Therefore, not only the pouch material 5B cut by the pouch material cutting blade 14 but also the subsequent pouch material 5A which has not been cut is mounted on the pouch material feeding belt 15 and conveyed to the punch 16. ing.

A second drive means 19 for driving the roller 15E is connected to the roller 15E for driving the pouch material feeding belt 15. Second drive means 1
A delivery belt speed control means 20 is provided between the sensor 9 and the sensor 18. The delivery belt speed control means 20 monitors the conveyance speed of the roller 13B constituting the pouch material introduction means 13 and detects it as a pulse,
Based on the result of the monitor, the conveyance speed of the pouch material delivery belt 15 by the second drive means 19 is controlled. More specifically, the conveyance speed of the pouch material feeding belt 15 is controlled to be faster than the conveyance speed of the pouch material introducing means 13 by a predetermined value α%. Therefore, the pouch material 5 </ b> B that has been cut and placed on the pouch material delivery belt 15 is transported at the same high speed as the pouch material delivery belt 15. Subsequent pouch material 5 not yet cut
A is the two rollers 1 constituting the pouch material introducing means 13.
Since it is conveyed while being sandwiched between 3A and 13B, it is conveyed at a slow speed by the pouch material introducing means 13. For this reason, the rear end 5D of the cut pouch material 5B and the leading end 5C of the succeeding pouch material 5A are configured to be always separated at a constant interval at the position of the punch 16 provided downstream. ing. The part of the subsequent pouch material 5A, which is on the pouch material feeding belt 15, is

It is possible to prevent the water from drooping down substantially vertically. The blade of the punch 16 is vertically movable and has a substantially star-shaped cross-sectional shape as shown in FIG. Punch driving means 21 for driving the punch 16 is connected to the punch 16. The punch driving means 21, as shown in FIG.
The punch 16 is driven when A coincides with the center position of the separated gap between the rear end 5D of the cut pouch material 5B and the leading end 5C of the succeeding pouch material 5A. By performing this punching, the portion corresponding to the corner of the pouch is cut into an arc shape and chamfered.

Punch 16 and pouch material feeding belt 15
Form one set, and in one set, the punch 16 is immovable with respect to the pouch material feeding belt 15. More specifically, as shown in FIG. 3, six pouch material feeding belts 15 are provided and four punches 16 are provided. In FIG. 3, the leftmost punch 16 and the pouch material feeding belt 15 form a first set, and the rightmost punch 16 and
Also, the pouch material feeding belt 15 forms a fourth set. Also, the second pouch material feeding belt 15 from the left
The punch 16 and the third pouch material feeding belt 15 from the left form a second set, and the second pouch material feeding belt 15 and the punch 16 and the third pouch material feeding belt 15 from the right are the second set. Make a set of three.
As described above, the in-line type pouch manufacturing apparatus 1 has a total of four sets. The four sets are integrally movable in the longitudinal direction of the pouch material delivery belt 15,
In the width direction of the pouch material feeding belt 15, the pouch material feeding belts 15 are configured to be able to come into contact with each other. Therefore, even when the pouches to be manufactured have various widths, the distance in the width direction of the belt 15 can be increased by bringing the sets into contact with each other.
That is, the distance between the sets can be adjusted to cope with this.

Next, a method for manufacturing the pouch will be described. Here, a method of manufacturing a pouch by cutting and punching wide pouch materials one by one using the in-line type pouch manufacturing apparatus 1 will be described. First, sheet introduction means 1
The two sheets 3 and 4, which are the front surface and the back surface of the plurality of pouches, are made flat by the 1 and are superposed, and are introduced into the heat seal portion 12. Next, in the heat-sealing portion 12, both edge portions of the two belt-shaped sheets 3 and 4 that are stacked are heat-sealed. Further, the sheet is heat-sealed with a predetermined width from one edge portion to the other edge portion in the width direction of the sheet, and the pouch material 5 to be a plurality of pouches is manufactured. Next, the pouch material 5 is transferred to the pouch material cutting blade 1 by the pouch material introducing means 13.
4, and is cut by the pouch material cutting blade 14. As shown in FIG. 3, the cut pouch material 5B
Is transported on the punch 16 at the same high speed as the pouch material feeding belt 15 because it is mounted on the four feeding belts. At this time, in FIG. 3, the third pouch material feeding belt 15 from the left and the third pouch material feeding belt 15 from the right prevent the pouch material 5 being conveyed from sagging. Subsequent pouch material 5A
Is conveyed in a state of being sandwiched between the two rollers constituting the pouch material introducing means 13, the pouch material introducing means 1
It is conveyed to the punch 16 at a slow speed according to 3. The rear end 5 of the pouch material 5B cut by the difference in the speed of conveyance
The D and the tip 5C of the subsequent pouch material 5A are separated from each other.
As shown in FIG. 5, the punch 1 is located at the center of the separated portion.
When the position 6 is reached, the delivery belt speed control means 20 simultaneously stops the pouch material delivery belt 15 and the pouch material introduction means 13. Along with this, the conveyance of the cut pouch material 5B and the succeeding pouch material 5A is also stopped. Then, only the outer two of the four punches 16 shown in FIG. 3 are driven by the punch driving means 21, the portions corresponding to the corners of the pouch are cut in an arc shape, and the chamfered pouch becomes Manufactured. The in-line type pouch manufacturing apparatus according to the present embodiment is a so-called three-chamfering type capable of manufacturing a pouch by cutting and punching three pouch materials for one pouch at a time. When three pouches for three pouches are cut at one time and punched to manufacture three pouches each having a narrow width at a time, four punches 16 shown in FIG. 3 may be simultaneously driven.

In the conventional in-line type pouch manufacturing apparatus, it was difficult to make a cut by a punch after cutting the pouch material as in the present invention. If such a configuration is adopted, after the pouch material is cut, while the pouch material is moved to a position where the pouch material is punched by a roller or the like, the cut pouch material is It may move in an unexpected direction with respect to the pouch material. When punching while moving in an unexpected direction, a cut is made at an unexpected position, and it is impossible to obtain a chamfered state. Therefore, in order to prevent the cut pouch material from moving in an unexpected direction with respect to the succeeding pouch material, the pouch material is conveyed by sandwiching the pouch material between two rollers facing each other and contacting each other. Need to take. This makes the structure of the device complicated and makes the device itself very expensive. For this reason, in the case of an apparatus that can perform punching cleanly and is not expensive, it has been avoided to adopt a sequence of cutting the pouch material and then making a cut with the punch.

However, in the in-line type pouch manufacturing apparatus according to this embodiment, the pouch material feeding belt 15 is provided, and the pouch material introducing means 1 is provided by the second driving means 19.
At a speed faster than the speed at which the pouch material is conveyed by 3,
Since the pouch material delivery belt 15 is driven so as to convey the cut pouch material 5B, the rear end 5 of the cut pouch material 5B at the punching position.
It is possible to separate D from the tip 5C of the subsequent pouch material 5A. Since this separated portion has a predetermined width, punching so that the tip end 16A of the blade of the punch 16 is positioned within the separated portion will make the pouch be chamfered cleanly. You can Therefore, even if the punch position is slightly deviated from the planned position, it is possible to prevent the occurrence of "tsutsu". Further, since the vacuum belt constituted by the timing belt 15A is used, the feeding accuracy when the pouch material 5 is conveyed in the downstream direction can be improved, and the cut pouch material 5B can be obtained.
Can be prevented from moving in an unexpected direction, and chamfering can be performed at a more accurate position at the punch position. Further, it is possible to avoid complicating the structure of the pouch manufacturing apparatus.

Further, the delivery belt speed control means 20 is provided to control the delivery speed of the pouch material delivery belt 15 by the second drive means 19 based on the result of monitoring the delivery speed of the pouch material introduction means 13. ,
The conveying speed by the pouch material feeding belt 15 can be controlled extremely accurately so as to be faster than the conveying speed by the pouch material introducing means 13 by a predetermined value α%.

The three-dimensional pouch according to the present invention is not limited to the above-mentioned embodiment, and various modifications and improvements can be made within the scope of the claims. For example, in the present embodiment, so-called R chamfering is performed in which the portion corresponding to the corner of the pouch is cut into an arc shape by the punch 16, but the present invention is not limited to this. For example, so-called C chamfering may be performed in which a straight line is cut.

In this embodiment, six pouch material feeding belts 15 are provided and four punches 16 are provided, but the number of pouch material feeding belts and the number of punches are not limited to these. .
