Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bagging device, and an object of the present invention is to provide a bagging device that facilitates the bagging operation of agricultural products, especially raw shiitake mushrooms, and improves work efficiency.

In general, when packaging agricultural products into sachets, they must be processed and shipped as quickly as possible after harvest in order to maintain freshness. Moreover, usually a relatively small number of people have to process a fairly large amount of material. In this way, intensive work for short periods of time is an essential condition, and this is a situation that limits production volume. Therefore, attempts were made to bring the produce to a collection point and package it in bulk using high-speed automatic packaging machines. However, agricultural products generally differ in quality and shape, and bulk packaging using high-speed automatic packaging machines cannot precisely respond to the quality and shape of each child. This causes dissatisfaction among the producers who shipped the products, which is an obstacle to the centralized packaging system.

The present invention provides extremely simple, easy-to-work, and efficient sachet packaging that overcomes the bottlenecks of sachet packaging of agricultural products such as raw shiitake mushrooms as described above. That is, the apparatus of the present invention is characterized in that it mechanizes the most troublesome task of bag filling work, which has traditionally been done entirely by hand, by producers. Moreover, the sorting of agricultural products is the same as before, so the problems that occur in the case of centralized packaging systems do not occur.

The apparatus of the present invention will be explained below with reference to the drawings.

As shown in FIGS. 1N and 2, the tooth 6 is provided at the negative end of the soft plate 1 at a length that fits into the small groove 21 at the mouth of the bag body, and an adhesive 3, for example, an adhesive type adhesive, is provided in the small groove 2. Pour the melt to fill the small groove. In this way, a thick adhesive band 4 is formed at the end of the soft plate 1.

Flexible Board A flexible foam board such as Ka polyurethane foam is preferred. The flexible plate 1 is inserted into an outer shell 6 with a hinge 5.5'. Adhesive board 7.7'Y configured in this way
As shown in FIG. 3, the two adhesive strips 4.4' are mounted facing each other, for example, by means of hinges 5.5', with the adhesive strips 4.4' facing inside.

One aspect of the operating method of this device will be explained with reference to FIGS. 3 to 5.

The upper and lower adhesive plates 1 and T', which are installed with hinges 5 and 5', are opened in the direction of the arrow by the handle 8 as shown in FIG. 3, and the bag 9 is placed on the lower adhesive plate 1'.

Next, as shown in Figure 4, close the upper adhesive plate 1v and lower the lower adhesive plate? 'Push to. At this time, the ends of the upper and lower soft plates 1.1' are compressed, and the adhesive strips 4.4' are adhered to both upper and lower surfaces of the opening of the bag body S in a peelable state. Next, as shown in FIG. 5, the upper adhesive plate 7 is held open by adhering both sides of the openings 9 to the upper and lower adhesive bands 4 and 4', respectively, and the packaged object 10 (for example, fresh shiitake mushrooms) is placed on the upper adhesive plate 7. etc.) and finish bagging.

Adhesion between the adhesive band 4.4' and the upper and lower surfaces of the bag body 9 can be achieved by appropriately selecting an adhesive type hot-melt material as an adhesive (for example, Hirodyne Co. 1500, Nitta Gelatin, etc.).
HT400. Kanebo NSC-Duro-Tax
134-4014% Cemedine HM-405, etc.) After the above-mentioned bagging operation has been completed, the bag can be easily peeled off from the adhesive band and taken out.

Generally, when adhesion and peeling are repeated using an adhesive type coating material as in the device of the present invention, the bag body cannot be opened because the adhesive robbery is lower than in K due to the consumption of the coating material and the contamination of the coating material surface. It becomes like this.

The present inventors conducted numerous tests to prevent the above-mentioned decrease in adhesive strength, and found that by pouring adhesive type Honmelt into the small grooves to a thickness of 5 to 10- or more, the adhesive strength was increased. We have discovered that scales can prevent the decline of The exact reason why the adhesive strength does not decrease is unknown, but the present inventors speculate as follows. That is, in the case of repeated operations of adhesion and peeling on the surface of a relatively large amount of adhesive hot melt as in the present invention, the cohesive force of the hot melt itself, f: J1, is very large, and the transfer of the real melt to the surface of the bag. This is because the force 1 is almost completely gone. Next, if the hot melt surface becomes contaminated and the adhesive strength decreases, (4) Clean it with an appropriate method. (4) Perform a mechanical cutting operation on the thin layer of the Ti surface, which heats only the surface for a very short time. Adhesion strength f can be determined by simple means such as
It recovered to '1 and scales and b1 were confirmed.

An example of packing raw shiitake mushrooms into sachets containing 100 pieces using the apparatus tVc of the present invention was as follows. The equipment operated smoothly and the bagging process was easy.

Implementation period: 3 months, shipment quantity: Approximately 2,000 bags, 7 days Sachet filling speed: 110 to 150 bags/hour For comparison, the conventional manual bag filling work speed f was 80 to 100 bags/hour. The excellent workability of the device of the present invention was confirmed.
