Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to soups such as ramen, buckwheat noodles, udon, sauces, sauces and other dressings, shampoos, liquids such as drenches, powder soups, spices, oysters, desiccants, oxygen scavengers, For individually packaging individual packaging bags containing contents such as anti-molds, powdered medicines, and granules, which are continuously placed via a coupling piece, for cutting into individual packaging bags one by one and inserting them into a container or the like. The present invention relates to a connecting bag separating device.

[0002]

2. Description of the Related Art Heretofore, there has been known a separating device for cutting a connecting bag body in which individual packaging bags are connected through a connecting piece as described above, into a container or a bag by cutting the connecting bag body one by one with a cutter. ing. In this conventional separating device for a connected bag, as in the invention described in Japanese Patent Laid-Open No. 54-54791, a connected bag body in which individual bags are connected via a connecting piece is arranged in the vertical direction, and the individual bag is connected. Belt conveyors that connect to the sensors are placed on both sides in the thickness direction.

Then, the connecting bag is moved while sandwiching both sides of the connecting bag with a pair of belt conveyors, and the individual bag of the connecting bag and the connecting piece for connecting the individual bags are connected to the photoelectric tube. Each individual bag is put into a container bag or the like by detecting with a sensor such as, and cutting the connecting piece with a cutter controlled by this detection signal.

Further, the connection of the connecting bag body in which the individual packaging bags are connected is performed by sealing three or four sides of the individual packaging bags. Two of the individual packaging bags in the coupling direction are coupling pieces, and the other one or two sides are side surface seals provided on one or both sides in the longitudinal direction of the coupling bag body.

[0005]

The three-sided or four-sided sealing of the individual packaging is generally performed by heat-sealing the packaging material of the connecting bag. When this heat-sealing is performed, the heating portion of the connecting bag body undergoes thermal contraction, and the thermal contraction often causes the connecting bag body to be partially bent or distorted from the sealed portion.

[0006] When the connecting bag body which is bent or distorted in this way is sandwiched and moved by the belt conveyor from both sides in the thickness direction, it is difficult for the connecting bag body to move linearly and the transfer direction Move from the axis line of. Then, when the connecting piece between the individual bags is detected by a sensor such as a photoelectric tube in order to cut the individual bag from the connecting piece, the connecting bag is transferred between the endless belts while being displaced from the axis of the transfer direction. Then, there is a drawback that a sensor such as a photoelectric tube cannot distinguish between the individual packaging bag and the connecting piece, or the connecting piece and the eye mark cannot be detected, and cutting or the like cannot be performed.

The present invention is intended to solve the above-mentioned problems, and the connecting bag body in which the individual packaging bags are connected via the connecting piece is cut and separated from the connecting piece portion one by one to form a container. In order to store the bag in a bag, etc., the connecting bag body should be transferred while being pinched by a pair of endless belts, and the transfer of the connecting bag body may cause lateral displacement or meandering at the nipping interval of the endless belt. It is something that should be avoided.

[0008] Then, the connecting bag body in which the individual packaging bags are connected by the heat-shrinking connecting piece can be always linearly transferred in a fixed direction, and the endless belt is arranged so as to face the discharging direction. Reliable detection of the connecting piece part by the sensor,
According to this detection signal, the cutter provided in the discharge direction transferred from between the endless belts is operated to surely cut the connecting piece between the individual packaging bags.

[0009]

In order to solve the above problems, the present invention presses a connecting bag body in which a plurality of solid bags for filling contents are connected via connecting pieces from both side surfaces in the thickness direction. A pair of endless belts to be sandwiched is formed, a sensor for identifying the connecting piece is arranged at the outer end in the transfer direction of the connecting bag body of the pair of endless belts, and a cutter for separating the connecting piece according to the detection signal of this sensor is installed. , Arranged on the extension of the connecting bag body in the transfer direction, and at the opposing interval of the pair of endless belts, the guide body is arranged through the widthwise interval of the individual packaging bag filled with the contents, The seal sliding portion is arranged in the facing direction of the guide body so that the seal portion of the connecting bag can be slid.

Further, the pair of endless belts may be one in which a pressing spring for pressing one endless belt in the opposite direction is arranged and one endless belt is pressed and biased toward the other endless belt.

[0011]

Since the present invention is constructed as described above, in order to separate a connecting bag body in which a plurality of individual bags are connected through connecting pieces, the connecting bag bodies are connected to each other. , Insert into the space between a pair of endless belts arranged horizontally or vertically.

This endless belt may be formed with an interval that allows the connecting bag body to be held in that interval, or one endless belt may be pressed and urged against the surface of the other endless belt by a pressing spring. .

As described above, the endless belts in which the connecting bags are inserted in the spaces arranged in parallel rotate in a fixed direction and convey the connecting bags in the conveying direction. Then, by transporting the endless belt sandwiched under pressure in the transport direction, the interval between the individual packaging bag sent from the endless belt and the connecting piece is cut by a cutter, and separated into individual packaging bags. The bag can be stored in the intended container, bag, etc.

Further, this connecting bag causes heat shrinkage of the film due to a connecting piece formed between the individual packaging bags and heat sealing of a seal portion formed on both sides or one side in the length direction of the connecting bag. It is unavoidable that the connecting bag body is deformed, distorted, or bent.

As described above, the connecting bag having the connecting piece and the seal portion which are distorted or curved is difficult to carry in the linear direction when being carried while being sandwiched between the pair of endless belts.
In the past, deviations were likely to occur from the axis of the transfer direction.

In the present invention, the guide bodies are arranged at the facing intervals of the endless belt. The guide body is formed by being interposed in the space between the endless belts, which is generated due to the thickness of the individual packaging bag interposed between the pair of endless belts. The guide bodies are arranged on both sides of the connecting bag body in the lengthwise direction so as to correspond to both sides of the individual packaging bag, and both sides of the connecting bag body can be abutted by the guide body.

With the guide bodies provided on both sides of the individual bag, the transfer direction of the connecting bag body is specified in a fixed linear direction, and the axis line of the transfer direction is not displaced or bent. . For that reason, the sensor provided facing the outer end of the endless belt in the transport direction is sure to have the connecting piece provided between the individual packaging bags of the connecting bag body sent linearly or the eye mark provided on the seal part. It is possible to determine.

By operating the cutter in accordance with the detection signal of this sensor, the individual bag can be surely cut. In addition, since the guide body has seal sliding portions formed inwardly, which can slide by arranging the seal portions provided on both sides or one side in the length direction of the connecting bag body, The seal does not obstruct the transfer of the individual bag by the guide body.

Further, the connecting bag body conveyed by the endless belt can be cut from the connecting piece by a cutter arranged in the feeding direction of the endless belt. In this cutting, when the connecting piece is transparent and the content stored in the individual packaging is opaque, the connecting piece or the content can be detected by using a transmission sensor, and the cutting can be performed by a cutter.

Further, by forming an eye mark for detecting the cutting position on both sides or one side in the length direction of the connecting piece, the cutting position of the connecting piece of the connecting bag can be detected by detecting this eye mark. It is possible to specify.

The eye mark formed on the connecting bag has a small area in general, and when the connecting bag is twisted or meandered, the eye mark is moved from the corresponding position of the sensor for detection. It cannot be detected because it is misaligned. As a result, the cutting position cannot be determined,
The individual bag is likely to be damaged without cutting the connecting piece.

According to the present invention, since the guide body regulates the transfer direction of the connecting bag body so that the connecting bag body can always be moved linearly, the eye mark or the connecting piece can be surely discriminated by the sensor. It is possible. Since the cutter can be operated according to the position of the sensor, the connecting bag body in which a plurality of individual packaging bags are connected through the connecting piece is surely cut and separated from the connecting piece portion, and the target container It can be stored in a bag, etc.
