Description

[Detailed description of the invention] [Industrial application field] The present invention mainly involves sealing a bag formed by storing a required amount of enoki mushrooms, bean sprouts, green peppers, etc. after expelling the air inside the bag. This invention relates to a degassing sealing machine that can perform continuous and automatic work.

[Conventional technology]

Taking enoki mushrooms as an example, the required amount of enoki mushrooms placed in a plastic bag naturally requires transportation time, storage time at stores, display time, etc., so the freshness is maintained for a certain period of time. It is necessary to maintain In particular, when it comes to fungi such as enoki mushrooms, or bean sprouts, their freshness decreases due to contact with oxygen, and changes that are undesirable as food may occur. One possible way to prevent this is to use vacuum packs, but for vegetables, mushrooms, etc. that do not need to be stored for a long time after shipment, and because of their nature, they are not suitable for vacuum packs. In some cases, it is sufficient to prevent deterioration due to oxygen within the bag for a certain period of time.

Therefore, in order to prevent the stored items from deteriorating due to oxygen over a certain period of time, it is possible to maintain the freshness of the stored items by deaerating the air inside the bag. I was going to work.

[Problem that the invention attempts to solve]

However, when it comes to bags of vegetables and mushrooms of this type, a considerable amount of food is packed into the bag, so manual degassing takes a lot of time and is inefficient. Furthermore, since it is necessary to seal the bag, the process is complicated and requires skill, and there is a risk that the air inside the bag may be shipped in an insufficiently evacuated state or without being evacuated. From this point of view, it is possible to perform this degassing work continuously and automatically with one device, and at the same time perform the sealing work, exhaust the air warmed by the sealing work, and perform the required length above the sealing part. The advent of a degassing and sealing machine that can cut continuously, improve work efficiency, and prevent stored items from deteriorating due to oxygen as much as possible, providing fresh vegetables, mushrooms, etc. to households. was awaited.

[Means to solve the problem]

The present invention was devised in view of the above points, and the above-mentioned problems can be solved by using a conveyor that stores and continuously conveys stored items, where the freshness of stored items is maintained by deaerating the air inside the bag. , an exhaust means comprising a clamping member located opposite to the middle part of the conveyor, which grips the middle part of the opening of the open-shaped bag being conveyed and pushes out the air inside the bag toward the end of the opening; An intake/exhaust member that forcibly takes in the discharged air and exhausts it outside the base; a heater located in the middle of the conveyor behind the exhaust means for heat-sealing the opening of the deaerated bag; a cooling member located behind the heater member for cooling the bag seal portion warmed by the heater member; a cooling member located opposite the midway portion of the belt conveyor behind the cooling member above the seal portion of the bag body; The present invention is solved by a degassing sealing machine characterized by being equipped with a ring cutter for cutting the part into a required length.

〔Example〕

The following description will be made based on the embodiments shown in the drawings.

1 in the figure is the main body of the degassing sealing machine of the present invention.
Reference numerals 2 and 3 indicate pulleys that grip and convey the open bag 5 containing the stored items 4. 6a,
Reference numeral 6b denotes a deaeration guide which faces each other with a narrow interval above and below the conveyance path of the open bag 5;
It serves as a support part during the degassing process.
Reference numerals 6 and 6' denote V-belts located in the middle of the conveyance path of the open bag 5. By holding the open bag 5 supported by the degassing guides 6a and 6b, the air inside the bag is removed from the opening. It is pushed out towards the end. 8 is a vacuum attached to the base 7,
Air is forcibly taken in from the box that stores the air discharged by the V-belts 6 and 6', and the exhaust pipe 9
This means that more water is emitted. Reference numeral 10 denotes a heater section that clamps and heat-seals the opening midway of the open bag 5 that has been transported after the degassing step, and is located midway through the open bag transport path. 11 is the heater section 10
A large number of holes 13 are bored in the box-shaped cooling guide, which is a cooling section located at the rear of the box-shaped cooling guide located above and below the midway portion of the open-shaped bag conveyance path.

[Operation of the present invention] The open bag body 5, which stores the stored items 4 which are conveyed while being held between the two pulleys 2 and 3, is conveyed while being supported by the degassing guides 6a and 6b. As shown in Figure 3, the middle part of the opening is held between V-belts 6 and 6' located opposite to the middle part of the conveyor, and the air inside the bag is pushed out toward the end of the opening, and the bag is installed in the base 7. The vacuum 8 forcibly takes in the discharged air and exhausts it to the outside of the base 7 through an exhaust pipe 9 inside the base 7. Next, the bag 5 from which the air inside the bag has been removed is transferred to a sealing process, and the opening midway is thermally sealed by the heater unit 10. Next, in order to cool the bag seal part warmed by the heater part 10 and return the bag to normal temperature, a large number of holes 13 are bored in the cooling guide 12 shown in FIG. 5 by the cooling part 11 located at the next stage. By means of discharging warmer air,
This is to return the bag to room temperature. The cooled bag body 5 is then cut at the upper part of the seal portion to a required length by ring cutters 14, 14 located opposite to each other in the middle of the conveyor, and then sent out.

[Effect of idea]

In the present invention having the above configuration, for stored items such as enoki mushrooms that require deaerating the air inside the storage bag in order to maintain freshness as much as possible for a certain period of time, the degassing process and the sealing process after degassing are performed. There is no need to do this manually, and it can be done automatically and continuously in large quantities, so unlike vacuum packaging, which aims to prevent stored items from deteriorating for a considerable period of time, it is possible to For items such as vegetables and mushrooms, which ideally need to maintain their freshness at the time of shipment for a certain period of time, they can be transported and stored in suitable conditions, and at the same time can be stored using heat-sealed seals. It quickly exhausts warm air, protects stored items, and allows continuous cutting to a fixed size above the sealing area, which further improves work efficiency. By using the stored items in the bag and the stored items from which the required amount of air has been removed by the device of the present invention, it is possible to extend the freshness maintenance time, and
This can have great effects, such as completely preventing the deterioration of stored items and, in the case of fungi such as enoki mushrooms, abnormal growth of unnecessary parts.
