Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag sealing device for supplying and storing items in a bag through an opening (bag mouth) of the bag and then closing the opening of the bag by heat sealing. .

[0002]

2. Description of the Related Art For example, Japanese Patent Application Laid-Open No.
2. Description of the Related Art An automatic packaging apparatus disclosed in, for example, Japanese Patent No. 327487 and having the following configuration is known.

At a stop position of a belt conveyor device for sequentially placing and transporting a plastic film bag of an upper opening type,
A suction opening mechanism for sucking the film at a position opposite to the upper opening of the bag and opening the film widely, and a storage material supply mechanism for supplying and feeding the storage material into the bag from the opening which is wide open by the suction opening mechanism. At the next stop position of the conveyer device which sends out the bag after storing the items in the bag, a seal mechanism for heat-sealing and closing the opening of the bag is provided.

More specifically, the suction opening mechanism is provided with a suction device in which a pair of suction portions are disposed so as to approach and separate from each other at a position sandwiching the upper opening of the bag. The opening portion is wide open by moving the suction portion facing the other to approach and separate the film at the position opposed to the opening portion and moving away.

[0005] Further, the stored article supply mechanism is disposed above an opening of the bag widely opened by the suction opening mechanism, and for example, a predetermined amount or a predetermined number of stored articles are directed toward the opening of the bag. It is configured so that it is automatically put in by being automatically dropped in sequence.

Further, the sealing mechanism is configured so that the opening of the bag in which the stored items have been stored is closed by heat sealing by sandwiching the opening with a pair of heat sealing portions.

Accordingly, in such a conventional automatic packaging apparatus, for example, a bag made by a bag making mechanism, a bag made in advance, or a bag containing predetermined storage items is placed in the upper part. Are sequentially placed and conveyed by the belt conveyer device in a state in which the bag is opened, and when stopped at a position below the storage material supply mechanism, the suction opening mechanism is operated, and the opposing suction section of the suction device is moved closer to the upper opening of the bag. The film is clamped slightly below the portion, and the film at the position opposite the opening is sucked by the vacuum suction force generated in the suction portion.

[0008] When the suction unit moves away, the respective films are pulled outward (while still adsorbed by the suction unit), and the opening of the bag is opened widely.

Then, in a state where the opening is widely held by the suction force of the suction portion, the upper stored material supply mechanism operates to automatically drop a predetermined stored product into the bag, thereby completing the supply and storage of the stored product. .

[0010] The bag is sent out again by the belt conveyor device, and the seal mechanism is operated at a predetermined stop position, so that the upper opening is closed by heat sealing.

[0011]

However, this type of conventional sealing device, such as the above-described automatic packaging device, simply opens a bag widely to supply and store a predetermined storage item, and then stores the bag. Is carried out to a predetermined position provided with a seal mechanism, for example, a pair of heat seal portions are sandwiched from one end of the opening of the bag to the other end on the opposite side to close the heat seal, or a pair of rolls This is merely a configuration in which the bags are successively clamped while being fed at the heat seal portion to close the heat seal.

Therefore, especially in the case of a bag such as a gusset bag in which a pair of opposing portions are bent inward at the opening and protruded so as to protrude, if the bag is simply clamped by the heat seal portion as it is, At the center of the opening, two films are stacked, but at both ends, four films are stacked.

[0013] For this reason, since the overlapping state of the film differs depending on the location, the sealing state becomes unstable depending on the location, and there is a case where the good sealing closure with the uniform sealing state is not performed.

In addition to the above-mentioned gusset bag, even when the bag is wrinkled, or the opening of the bag is not neatly formed and is rounded, similarly, the degree of film overlapping can be improved. Are non-uniform, causing the above-described problem.

On the other hand, in order to solve such a problem, simply increasing the amount of heat in the heat seal portion increases the cost, and conversely, the amount of heat may be excessive in the portion where two sheets are overlapped. Setting is not easy.

The present invention finds such a problem in the conventional sealing device, and arranges two opening portions of the bag along the sealing direction before closing the heat seal by a simple means and configuration. It is an object of the present invention to provide an epoch-making bag sealing device capable of uniformizing the degree of film overlap, uniforming and stabilizing the sealing state, and performing good sealing without defective sealing. .

And a sealing mechanism for closing the opening 2 of the bag 1 at the next stop position of the conveying device 8 for feeding the bag 1 again after storing the storage item 3 in the bag 1. 9 is provided.

Further, after the storage item 3 is supplied and stored in the bag 1 by the storage item supply mechanism 4 at a position where the suction opening mechanism 5 and the opening holding mechanism 7 are provided, Before sealing the opening 2 of the first opening 2, the opening 2 of the bag 1 is overlapped with two films from the one end 2 A of the opening 2 in the sealing direction of the sealing mechanism 9 to the other end 2 B on the opposite side. An opening shaping mechanism 11 in which a shaping unit 10 for adjusting the shape is provided so as to be able to retreat and move is provided.

The opening shaping mechanism 11 of this embodiment is specifically configured as follows.

The shaping section 10 is formed in a rod-like two-body configuration, and is illustrated from the position retracted outside the bag such that the tips of the shaping sections 10 face each other above the opening 2 of the bag 1. The bag 1
One end 2A of the opening 2 and the other end 2B on the opposite side of the opening 2 are pressed outward in the bag 1 so that the respective shaping portions 10 are respectively connected to the one end in the bag 1. 2A and the other end 2B, the film of the opening 2 is moved from the one end 2A to the other end 2B.
The opening shaping mechanism 11 is configured so that the film facing each of the openings 2 is stretched and held until the opening B is reached, and the films facing each other in the opening 2 are stretched and arranged in a closed state in a two-ply state.

The suction opening mechanism 5, the stored article supply mechanism 4,
The description of the seal mechanism 9 will be omitted because it is the same as that described in the related art.

Further, after the opening 2 of the bag 1 opened widely by the suction opening mechanism 5 is widely held by the opening holding mechanism 7, the suction force of the suction opening mechanism 5 is released. Specifically, the opening holding mechanism 7 has a structure in which the holding portion 6 has a rod-like four-body structure, and the tip of each holding portion 6 faces each other above the opening 2 of the bag 1 so as to be outside the bag. From the retracted position, the tip of each holding portion 6 is turned down toward the four corners in the bag 1 where the holding portions 6 are separated from each other by a rotation driving device (not shown), and each holding portion 6 The bag 2 is configured so that the opening 2 is widely held by hanging down at four corners of the opening 2.

Therefore, in this embodiment, as shown in FIGS. 1 and 2, the bags 1 made of a plastic film having an open top are sequentially conveyed by the conveying device 8, and as shown in FIG. When stopped at the lower position, the suction opening mechanism 5 is operated, and the opposing suction portion 12A of the suction device 12 moves close to and closes the lower portion of the upper opening 2 of the bag 1, as shown in FIG. The film at the position opposite to the opening 2 is sucked by the vacuum suction force generated by the suction section 12A.

Then, as shown in FIG. 5, when the suction portion 12A moves away with the suction force applied thereto, the respective films are pulled outward (while still being sucked by the suction portion), and the opening of the bag 1 is opened. The part 2 opens widely.

At this time, as shown in FIG. 6, the opening holding mechanism 7 is operated, and the four-piece rod-shaped holding parts 6 are placed in a substantially horizontal state with their leading ends facing each other. 2 From the position retracted upward, the respective holding portions 6 are rotated downward and dropped down to the four corners of the bag 1 so as to be separated from each other,
The opening 2 of the bag 1 is widely held.

The operation of the opening holding mechanism 7 causes the opening 2
Suction opening mechanism 5 that has finished its function
Stops its suction action.

Each holding section 6 of the opening holding mechanism 7
The upper stored material supply mechanism 4 is operated in a state where the opening is widely held, and a predetermined stored product 3 is automatically dropped into the bag 1 and the supply and storage of the stored product 3 is completed.

After the supply and storage of the storage items 3 are completed, the holding portions 6 of the opening holding mechanism 7 return upward and rotate to retreat outside the bag, and at the same time, the reshaped opening shaping mechanism 11 is reshaped. The opening 10 of the bag 1 is closed by the part 10 so that two films are stacked in a closed state from one end 2A of the opening 2 in the sealing direction of the sealing mechanism 9 to the other end 2B on the opposite side.

More specifically, for example, the two shaping sections 10 that have been retracted above the opening 2 of the bag 1 are respectively turned downward and inserted into the bag 1. The film of the opening 2 is stretched and held from the one end 2A to the other end 2B by hanging down at the one end 2A and the other end 2B opposite to each other in the bag 1. Then, the films facing each other in the opening 2 are arranged in a stretched state and are arranged in a two-ply shape.

After the shaping section 10 returns to the outside of the bag and turns up and retracts, the suction section 12A of the suction opening mechanism 5 is further moved.
Move closer to each other in a suction force released state (a state without suction force) to press and hold the opening 2 and separate from each other, thereby securely forming a two-layered closed state.

Then, the bags 1 are fed out again by the belt conveyor device 8, and at the next stop position, the sealing mechanism 9 is operated, and the heat sealing portion 9A is closed so that two sheets are stacked from one end 2A to the other end 2B. By sandwiching the opening 2 shaped like a hole, the opening 2 is configured to be closed by heat sealing.

Therefore, before the opening 2 of the bag 1 is sealed and closed by the sealing mechanism 9, the film is arranged in a substantially straight line parallel to the sealing direction from one end 2A to the other end 2B so as to be closed. Seal closure by the seal mechanism 9 can be performed satisfactorily. That is, even if a part of the opening, such as a gusset bag, is habited to protrude inward, and even if wrinkles are generated, the sealing portion uniformly overlaps two sheets over the entire length by the shaping action. In order to stabilize the sealing state, the film is not formed unevenly, and it is not uneven, depending on the location. Insufficient seals are less likely to occur,
Good seal closing can be performed.

Further, each of the shaping portions 10 is inserted into the bag 1 by rotating downward from a position retracted outside the bag 1 and inserted into the bag 1. The opening shaping mechanism 11 is configured so that the openings 2 of the bag 1 are arranged in a two-ply configuration by hanging down one end 2A in the direction and the other end 2B on the opposite side.
Since a series of operation operations of rotating and hanging down from the position retracted to the outside of the bag above the opening 2 of the bag 1 may be sufficient, the opening 2 of the bag 1 can be formed by a simple configuration and simple operation control.
Are arranged in two layers over the entire length in the sealing direction,
The degree of overlap can be made uniform.

Further, even if the hanging length of the rod-shaped portion of each shaping portion 10 is designed to be longer so that the shaping can be performed more reliably and favorably, it can be realized by the simple configuration as described above and simple operation control. Therefore, it will be extremely practical.

Therefore, when the bag 1 to be shaped before sealing is a gusset bag in which at least a pair of opposing portions of the opening 2 is formed by bending inward as shown, for example, the bag 1 is turned outwardly. The portion protruding inward is stretched outward in two folds by the shaping portion 10 which is drooped and disposed at both ends 2A and 2B, and the opening 2 is substantially linearly formed along the sealing direction. Because it can be shaped into a closed state, even if it is a gusset bag, a wrinkled bag, or even if the opening is rounded and wrinkled or folded, this opening shaping mechanism 11 By the shaping, the degree of overlap of the openings 2 is always uniformed in a two-layered manner, so that a good seal closing can be performed as described above.

When the bag 1 is transported from the side by a transporting device 8 such as a belt transporting device of a placing and transporting type, a two-body configuration is adopted so that the shaping action can be reliably exerted as described above. , And even a long drooping shaping section
Even if it is 10, since it is retracted substantially horizontally above the bag 1, it can be retracted above the bag 1 without taking up space, and the bag It can be easily carried out.

An opening mechanism 5, an inoculation mechanism 4 serving as the stored product supply mechanism 4 for feeding mushroom seeds 3 as the stored product 3 into the culture bag 1 from the opening 2 opened wide by the suction opening mechanism 5, An automatic inoculation device for mushroom species comprising a sealing mechanism 9 for sealing and closing the opening 2 of the culture bag 1, comprising the suction opening mechanism 5, the opening holding mechanism 7, and the opening shaping mechanism 11. The figure shows a case where the present invention is applied to an automatic inoculation device for mushrooms.

More specifically, the bag 1 to be transported and supplied is a culture bag 1 made of a plastic film having an upper opening and containing a culture medium 13, and a transport device 8 is a belt conveyor for sequentially placing and transporting the culture bag 1. The device 8 is used.

Further, the suction opening mechanism 5 is provided with the suction device 12 in which the pair of suction portions 12A are disposed so as to be able to approach / separate from each other at positions sandwiching the upper opening 2 of the culture bag 1 as described above. The opening 2 is wide open by moving the suction unit 12A of the suction device 12 approaching and adsorbing the film at the position facing the opening 2 and moving away therefrom.

The inoculation mechanism 4 as the storage material supply mechanism 4 is provided with the inoculum bottle 14 containing the mushroom inoculum 3 in an upside down state on the upper portion of the culture bag 1 which is widely opened by the suction opening mechanism 5, A predetermined amount of the mushroom seed 3 is automatically dropped into the culture bag 1 via the hopper 16 by inserting the scraping portion 15 into the seed bottle 14 and scraping the mushroom seed 3.

Further, the sealing mechanism 9 closes the upper opening 2 of the culture bag 1 having been inoculated by the inoculation mechanism 4 with the mushroom inoculum 3 by a pair of heat sealing sections 9A so as to close the heat sealing. Make up.

Therefore, for example, when the culture bag 1 sterilized together with the culture bag 1 is sequentially placed and conveyed by the belt conveyor device 8 with the upper part opened, and stopped at a position below the inoculation mechanism 4, the suction opening mechanism 5 is operated. Then, the opposing suction part 12A of the suction device 12 moves close to and clamps the lower part of the upper opening 2 of the culture bag 1, and is held by the suction part 12A of the opening 2 by the vacuum suction force generated in the suction part 12A. The film at the opposing position is sucked.

When the suction unit 12A moves away with the suction force applied thereto, the respective films are separated (at the suction unit).
Pulled outward from each other (while still adsorbed on 12A), the opening 2 of the culture bag 1 opens widely.

At this time, the opening holding mechanism 7 is operated, and the opening 2 of the bag 1 is widely held by the four rod-shaped holding portions 6.

The operation of the opening holding mechanism 7 causes the opening 2
And the suction operation of the suction opening mechanism 5 that has finished its function is stopped.

Then, each holding portion 6 of the opening holding mechanism 7
The upper inoculation mechanism 4 is held wide open by the
Is operated, the mushroom inoculum 3 is scraped off from the inoculum bottle 14 by the raking unit 15, and the mushroom inoculum 3 is automatically dropped into the culture bag 1 via the hopper 16, and the inoculation of the inoculum is completed.

After the supply of the storage items 3 is completed, the opening 2 of the culture bag 1 is sealed by the shaping section 10 of the retracted opening shaping mechanism 11 with the sealing mechanism 9 of the opening 2. From one end 2A to the other end 2B on the opposite side, the film is arranged in a closed state in a state where two films are stacked.

Then, after the shaping section 10 returns and rotates and retracts, the suction section 12A of the suction opening mechanism 5 further moves closer to the suction opening state with the suction force released, and presses and clamps the opening section 2 to securely hold the opening section 2. It is shaped like a two-layered closed state.

The culture bag 1 is fed out again by the belt conveyor device 8, and the sealing mechanism 9 is operated at a predetermined stop position, so that the upper opening 2 is closed by heat sealing.

[0065]
