Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates food items such as ramen sauce, liquid soup, spices, medicines, natto sauce, mustard, shampoos, chemicals, toys, electric appliance parts, etc. The present invention relates to a continuous individual packaging bag distributing device for cutting a plurality of individual packaging bags connected to each other and inserting the individual packaging bags into the insertion target portion.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Publication No. 59-18254 and Japanese Patent Publication No. 59-18255 have been used as a distribution device for separating a plurality of individual packaging bags connected by connecting pieces one by one from a connecting piece and putting them into a receiving container or the like. The inventions and inventions described in Japanese Utility Model Publication No. 7-47290 and Japanese Utility Model Publication No. 6-42624 are known. And Japanese Patent Publication No. 59-18254 and Japanese Patent Publication No. 59
In the invention described in Japanese Patent No. 18255, a continuous individual packaging bag supplied from the vertical direction is cut with a cutter to cut a connecting piece, and the individual packaging bag is free-falled through a chute arranged facing the lower part of the cutter. It is to be placed in a receiving container.

In the invention disclosed in Japanese Utility Model Publication No. 7-47290, a connecting piece of a continuous individual packaging bag which is horizontally transferred and supplied is cut by a cutter at a transfer destination, and the individually cut individual packages. The bag is adsorbed by the adsorption pad and put into the receiving container.

Further, in the device disclosed in Japanese Utility Model Laid-Open No. 6-42624, a connecting piece of a continuous individual bag supplied from the vertical direction is cut by a cutter and dropped on a conveyor belt which moves in the horizontal direction. This conveyor belt has suction holes
A vacuum suction force is applied through this suction hole to adsorb the individual packaging bag onto the surface of the conveyor belt, the individual packaging bag is transferred to the lower surface side of the transportation belt, and the individual packaging bag is arranged on the upper surface of the receiving container. At this point, the adsorption is released and the individual packaging bag is dropped into the receiving container.

[0005]

However, as in the inventions described in JP-B-59-18254 and JP-B-59-18255, the individual packaging bag whose connecting piece is cut by the cutter is received by free fall through the chute. In the method of throwing in the bag, the dropping speed was not constant, and it was difficult to reliably put the individual bag into the receiving container that was continuously transferred. In particular, if dew condensation occurs on the chute, or if the contents of the individual bag are damaged and the contents adhere to the chute, the falling speed of the individual bag will be significantly reduced, or the individual bag will stick to the chute and cannot be dropped. Things also happened.

Further, as in the invention described in Japanese Utility Model Publication No. 7-47290, the method of adsorbing individually packaged bags individually cut by a cutter with a suction pad and throwing them into a receiving container has a high feeding speed. It has a merit that even if dew condensation or content adheres to the member, it can be surely charged.
However, the method of adsorbing the individual packaging bags one by one and charging them into the receiving container is slow in charging speed and cannot meet the demand for high speed charging. Therefore, a method is also used in which the individual packaging bag with the connecting piece cut is not adsorbed by the adsorption pad and is knocked down by the pad and put into the receiving container, but the input is incorrect and It was easy for situations such as bouncing out of the receiving container to pop out.

Further, as in the invention described in Japanese Utility Model Laid-Open No. 6-42624, the individual packaging bag is adsorbed on the surface of the conveyor belt provided with the adsorption holes, and the individual packaging bag is transferred to the lower surface side of the conveyor belt to receive the container. When the individual packaging bag is placed on the upper surface of the container, the suction is released, and the individual packaging bag is dropped into the receiving container, which enables high-speed loading. However, if the connecting piece of the individual bag has a bend or the individual bag is deformed, part of the individual bag floats up from the conveyor belt, and the individual bag can adhere to the suction holes. Instead, it often happened that it accidentally dropped from the conveyor belt. Further, the device of this system has a complicated mechanism and is expensive, and requires a lot of labor for maintenance.

The present invention is intended to solve the above-mentioned problems and includes a plurality of individual packaging bags connected by connecting pieces.
When the pieces are separated from the connecting piece and separated and then put into the receiving container, it is possible to perform accurate feeding at a high speed and eliminate the leakage of the filling into the receiving container. As a result, it is intended to prevent the production line from being stopped and to prevent defective products from being produced, and to form an apparatus with a simple mechanism so that an inexpensive apparatus having excellent durability can be obtained.

[0009]

In order to solve the above-mentioned problems, the present invention connects a plurality of individual packaging bags for storing contents through a connecting piece, and connects the individual packaging bags horizontally. A cutter that cuts the connecting piece is placed at the transfer destination of the transfer mechanism to transfer, and the receiving blade that can be rotated and stopped by connecting to the rotating shaft is made to face the falling position of the individual bag cut by this cutter. It is arranged so that the individual bag cut by the cutter is temporarily received by the receiving blade, then the receiving blade is rotated, and the individual bag can be dropped into the receiving container placed below this receiving blade. is there.

Further, the receiving blades connected to the rotating shaft may be arranged so as to face each other on both sides of the dropping position of the individual packaging bag.

Further, the receiving blade connected to the rotating shaft may be arranged only on one side of the dropping position of the individual packaging bag.

Further, the receiving blade connected to the rotary shaft may be one formed on the rotary shaft.

Further, the receiving blades connected to the rotary shaft may be formed in a radial pattern on the rotary shaft at equal intervals.

[0014]

Since the present invention is constructed as described above,
In order to distribute the individual bags connected by the connecting pieces to the receiving containers, first, the individual bags connected by the connecting pieces are placed horizontally on a transfer mechanism such as a conveyor belt. Then, the transfer mechanism is operated to transfer the connected individual packaging bag in the cutter direction. Then, the connecting piece connecting the individual packaging bags is cut by the cutter of the transfer destination. The individual packaging bag is cut by the cutting of the connecting piece, and falls from a transfer mechanism such as a conveyor belt. Since the receiving blade that faces the falling position of the individual packaging and can rotate and stop is connected to the rotary shaft, the cut individual packaging falls and is received by the upper surface of the receiving blade. . After this receiving, the rotating shaft is operated to rotate the receiving blade, and the individual packaging bag can be dropped into the receiving container arranged below the receiving blade.

Since the individual packaging bag is first received by the receiving blades and then loaded into the receiving container, the individual packaging bag is kept in a constant attitude and pops out of the receiving container, or at the opening edge of the receiving container. There is no possibility of being caught and making the packaging of the receiving container difficult. In addition, the receiving container is also transferred to the dropping position of the individual bag by a conveyor mechanism such as a belt conveyor, but the timing of separating the connecting piece by the cutter and the transferring time of the receiving container to the loading position is set to the receiving blade. Therefore, it is possible to prevent the mistake of throwing the individual packaging bag.

In the present invention, as described above, the individual bag cut by the cutter is loaded into the receiving container by the receiving blade which can be rotated and stopped by connecting to the rotating shaft. Even if the receiving blade does not change and the receiving blade is condensed or the contents of the individual bag adhere to the receiving blade, the individual bag on the rotating receiving blade is not charged into the receiving container. It can be done reliably. In addition, since the receiving blade can be rotated and stopped according to the rotation axis, the operation speed is fast, and it is possible to insert the bag at a higher speed as compared with the case where the individual packaging bag is adsorbed by the adsorption nozzle and placed in the receiving container. . Further, the individual packaging bag is surely inserted into the receiving container, and the individual packaging bag does not splash after being inserted into the receiving container as in the case of being knocked off.

Further, the receiving blade connected to the rotating shaft may be one formed on the rotating shaft, but if a plurality of receiving blades are radially formed on the rotating shaft at equal intervals, the receiving blade is formed. After placing the individual packaging bag into the receiving container, the rotation angle of the rotating shaft until the next receiving blade faces the lower surface of the cutter becomes small, and multiple rotations can be made with one rotation of the rotating shaft. Becomes Therefore, the individual packaging bag can be loaded into the receiving container at high speed. However, if the number of receiving blades connected to the rotating shaft is too large, it will be difficult to place the individual packaging bag, so it is preferable to form the number of sheets to about 2 to 4.

Further, if the receiving blades connected to the rotating shaft are arranged so as to face each other on both sides of the falling position of the individual packaging bag, even if the individual packaging bag has a large size, two opposing receiving blades are provided. Since the individual packaging bag can be received by, the size of the receiving blade can be made smaller than in the case of receiving the individual packaging bag by one piece, and the distribution device can be downsized. However, when the size of the individual bag is small, the receiving blade can be arranged only on one side of the dropping position of the individual bag, and the mechanism can be simplified to obtain an inexpensive distributor. Become.

The connecting bag body (1) is formed by bending a single film and heat-sealing the outer peripheral portion of the individual packaging bag (2) to form a seal portion (4). It stores foods such as soups, spices, medicines, natto sauces, mustards, and contents such as shampoos, medicines, toys, and parts for electric appliances.

A fixed eye mark is formed on the seal portion (4).
(5) is formed corresponding to the connecting piece (3). And
The eye mark (5) can be discriminated by the sensor (6). In this case, attach the sensor (6) to the eye mark (5).
It corresponds to the seal part (4) provided with.

Further, the connecting bag body (1) can be conveyed in a fixed direction by a pair of upper and lower endless belts (7) and (8). The pair of upper and lower endless belts (7) and (8) are arranged in parallel, and are arranged in parallel with each other with an interval capable of pressing and sandwiching the individual packaging bag (2) of the connecting bag body (1). The pair of endless belts (7) and (8) have a plurality of guide pulleys (10) arranged inside the conveying surfaces to prevent bending. One of the endless belts (7) and (8) is formed by a movable conveyance belt that can move in a direction perpendicular to the conveyance direction, and the other is formed by a fixed conveyance belt that does not move its position. ing.

Then, the one endless belt (7) of the pair of endless belts (7) and (8) is pressed and urged from the outer surface side toward the other endless belt (8) by the pressing bar (11), By this pressing force, the individual packaging bag (2) connected by the connecting piece (3) can be sandwiched and conveyed in a fixed direction. And this one endless belt (7) and the other endless belt (8)
By synchronizing and rotating the facing surface in the same direction,
The connection bag body (1) to be inserted into the facing space (12) is sandwiched and can be conveyed.

While the connecting bag body (1) is sandwiched, the individual bag (2) is placed between the conveying surfaces of the endless belts (7), (8).
To form a facing distance (12) formed by inserting the. Further, the sensor (6) is arranged so as to face the outer ends of the endless belts (7) and (8) in the transfer direction. This sensor (6)
Further, a cutter (13) is provided on the outer side in the carrying direction, and the cutting position signal of the sensor (6) is output to the cutter (13).

The sensor (6) has a connecting piece (3).
If a transparent sensor such as a photoelectric tube is used to detect the position of the
It does not react with (2) and can be detected corresponding to the transparent connecting piece (3). Further, when the connecting piece (3) is opaque, it is difficult for the transmissive sensor (6) to distinguish it from the individual packaging bag (2). Therefore, the length of the connecting bag body (1) Attach the eye mark (5) to the seal (4) provided on the side surface in the direction of the connection piece (3).
Alternatively, the eye mark (5) may be identified by the reflection type sensor (6).

The sensor (6) thus constructed
By detecting the transparent portion of the connecting piece (3) or detecting the eye mark (5), a detection signal is sent to the cutter (13). The endless belts (7) and (8) receive the detection signal from the sensor (6), convey the central portion of the connecting piece (3) of the connecting bag body (1) to the cutting position of the cutter (13), and then stop, and the cutter (13) is activated, and individual packaging bag is started from the central part of the connecting piece (3).
Cut (2) and separate.

The receiving blades (14) are arranged so as to face the positions where the individually packaged bags (2) separated by the cutter (13) fall. The receiving blade (14) is connected to a rotating shaft (15) that rotates or stops rotating according to a signal from the outside, and can rotate and stop together with the rotating shaft (15).
From the cutting of the connecting piece (3) by the cutter (13),
The process of inserting the individual packaging bag (2) into the receiving container (16) via 4) is as shown in FIGS.

That is, as shown in FIG. 1A, when the individual packaging bag (2) is in a standby state for cutting the connecting piece (3), the receiving blade (14) is packaged individually.
It is placed at a right angle to the planned falling direction of (2). Next, as shown in FIG. 1B, connect the connecting piece (3) with the cutter (13).
When the bag is cut, the individual packaging bag (2) is temporarily received by the receiving blade (14). Then, as shown in C of FIG. 1, the individual bag (2)
When the receiving blade (14) mounted on the upper surface is rotated by the rotating shaft (15), the individual packaging bag (2) drops without changing its posture. Then, as shown in FIG. 1D, the receiving blade (14)
The individual packaging bag (2) is dropped into the receiving container (16) arranged below the container. Upon completion of this charging, as shown in FIG. 1A, the lower surface of the cutter (13) is connected with the connecting piece (3) to the individual packaging bag.
The following receiving blade (14) is arranged together with (2).

The receiving blade (14) connected to the rotating shaft (15)
Are arranged so as to face each other on both sides of the dropping position of the individual packaging bag (2), and four receiving blades (14) are radially formed at equal intervals on one rotating shaft (15). Then, the rotating shaft (15) having four receiving blades (14) formed thereon is arranged on both sides of the falling position of the individual packaging bag (2).

The receiving blade (14) connected to the rotating shaft (15)
May be one formed on the rotating shaft (15),
If a plurality of receiving blades (14) are radially formed on the rotating shaft (15) at equal intervals, the receiving blades (14) put the individual packaging bag (2) and put it in the receiving container (16). After that, cutter the next receiving blade (14)
The rotation angle of the rotary shaft (15) until it is exposed to the lower surface of (13) becomes small, and it is possible to make a plurality of injections with one rotation of the rotary shaft (15). Therefore, if a plurality of receiving blades (14) are formed on the rotating shaft (15), the receiving container (1
It is possible to input to 6). However, if the number of receiving blades (14) connected to the rotary shaft (15) is too large, it becomes difficult to mount the individual packaging bag (2). Therefore, two pieces or three pieces as shown in FIG. It is preferable to form about four sheets.

Further, the receiving blade (14) connected to the rotating shaft (15)
As shown in FIGS. 1 and 6, if the individual packaging bags (2) are arranged so as to face each other on both sides of the dropping position, even if the individual packaging bags (2) are large, the Receiving wings (14) for individual packaging (2)
Since the receiving blades (14) can be received, the size of the receiving blades (14) can be made smaller than in the case of receiving the individual packaging bag (2), and the distribution device can be downsized. Further, since the receiving blade (14) is rotated while the receiving blades (14) are held on both sides of the individual packaging bag (2), the individual packaging bag (2) is put into the receiving container (16). It is possible to perform the loading posture of the individual packaging bag (2) with almost no change from that during the transfer of the transfer mechanism. Therefore, not only can the individual packaging bag (2) be reliably loaded into the receiving container (16), but also the desired surface of the trademark, functional book, etc. displayed on the individual packaging bag (2) can be placed facing the surface. It is also possible to do.

When the receiving blades (14) are provided so as to face both sides of the dropping position of the individual packaging bag (2), the rotating shaft (15) naturally rotates in the left-right relative direction. Also, the rotation axis
(15) is an electric motor (17) such as a servomotor and a drive gear (2) through a meshing gear (18) for relative rotation.
0) causes relative rotation at a constant angle. The rotating shaft (15) can be driven by any method, and may be driven by the gear (18) meshing with the electric motor (17) as described above, or by a left-right linear motor. Alternatively, a timing belt, a cam mechanism, or a pneumatic drive mechanism may be used.

In the above-mentioned embodiment, the receiving blades (14) connected to the rotating shaft (15) are arranged to face both sides of the dropping position of the individual packaging bag (2). When the size is small, as shown in FIG. 7, it is possible to arrange the receiving blades (14) only on one side of the dropping position of the individual packaging bag (2). In this case, since the receiving blade (14) is arranged only on one side, the individual packaging bag
Although (2) is slightly inclined at the time of loading, it does not affect the loading into the receiving container (16) as long as the individual packaging bag (2) has a small size. Further, by disposing the receiving blade (14) only on one side of the falling position of the individual packaging bag (2), the mechanism can be simplified and an inexpensive distribution device can be obtained.

In one embodiment of the present invention, the distance between the fixed endless belt (8) forming the pair of endless belts (7) and (8) and the movable endless belt (7) is In the state where the connecting bag body (1) is inserted, the facing space (12) corresponding to the thickness of the contents of the individual packaging bag (2) of the connecting bag body (1) is generated. Guide bodies (21) and (22) having a thickness smaller than the facing distance (12) are formed in the distance between the endless belts (7) and (8).

The guide bodies (21) and (22) are connected bag bodies.
A pair is formed between the endless belts (7) and (8) with a space slightly larger than the formation width of the individual packaging bag (2) of (1). And, the guide body (21) (22) conveys the connecting bag body (1)
Various shapes can be formed according to the shape of the above, but it is necessary that the individual packaging bag (2) of the connecting bag body (1) has a thickness sufficient to abut from both sides. This thickness is an endless belt
(7) As long as it is narrower than the facing interval (12) of (8), it is preferable to have a thickness as much as possible.

As described above, the connecting bag body (1) sandwiched by the pair of endless belts (7) and (8) is attached to the guide bodies (21) and (22).
The sensor (6) provided at the outer end portion in the transport direction regulates the transport direction by means of the transparent coupling piece (3) and the eye mark (5) that are always transported on the same straight line. ) Etc. can be reliably detected, and the connecting piece (3)
It is possible to surely cut the central part of the with a cutter (13).

Further, in the above embodiment, the connecting bag body (1) is pressed and sandwiched by the pair of endless belts (7) and (8) and conveyed in a fixed direction, but in other different embodiments. As shown in FIGS. 4 and 5, the seal portion of the connecting bag body (1) is formed by using the pinch roller (23) and the feed roller (24).
The connection bag body (1) is formed by sandwiching (4). In the embodiment shown in FIG. 4 and FIG. 5, the pinch roller (23) which is a driven wheel and the feed roller (24) which is a driving wheel are
Since only the seal part (4) provided on one side of the connecting bag body (1) is sandwiched, the transfer surface of the connecting bag body (1) is prevented in order to prevent deviation in the transfer of the connecting bag body (1). Guide body (2
1) (22) is arranged. By using the pinch roller (23) and the fido roller (24) to transfer the connecting bag body (1), compared to the case where the connecting bag body (1) is transferred by the pair of endless belts (7) and (8), The device can be made inexpensive. However, as compared with the case where the connecting bag body (1) is transferred by the pair of endless belts (7) and (8), there is a drawback that transfer is likely to occur and the transfer speed becomes slow.
