Abstract

PURPOSE:To minimize the buckling of a molding and to make the volume thereof smaller and the density higher by pushing the molding which is compressed in the final compression chamber into a cartridge chamber set around with a cord for tying in the inlet and tying the molding in the compressed state then extruding the molding with the succeeding compressed molding. CONSTITUTION:The compressed molding 2 of dry grass or the like which is compressed in the final compression chamber 1 is pushed by a tapered inside surface 8 which is made narrower in the pushing direction to prevent the expansion of the molding into the cartridge chamber 3 provided with a projection 9 for preventing the push back on the inside surface near the inlet 4. The molding 2 maintains the compressed state without expanding in the respective directions of the outlet 7 and inlet 4; at the same time, the cord 5 for tying preliminarily set around the inlet 4 is hooked to the front surface of the molding 2 in the stage of the above-mentioned pushing and while the cord 5 is dragged by the top and bottom surfaces, the cord is automatically wound around the molding 2 and the molding is tied by a suitable means. The molding 2 is extruded from the chamber 3 by the force of the next molding when said molding is extruded and fed into the chamber 3 by a cylinder 14. The costs of packing and transportation are reduced and the collapsion of the packings is prevented by the above-mentioned method.

Description

[Detailed Description of the Invention] A. Purpose of the Invention (a) Industrial Application Field The present invention is directed to the use of hay such as grass, rice straw, sugar cane leaves, etc.
The present invention relates to a method of bundling and taking out products while maintaining high density after compression molding in the final compression chamber of a compression molding machine, and a device used therefor.

b. Conventional technology In order to transport hay from a supply area to a demand area to use it as roughage, it is necessary to reduce the volume, reduce intercoloration and transportation costs, and compression mold it to prevent the load from collapsing.

In the hay compression molding machine for this purpose, the conventional compression molded product outlet simply has an opening in the final compression chamber. The compression molded product recovered therefrom is in an open state, and expansion due to restoration staking, that is, bank ring, is large.

The tiles tied together with string usually have a width x depth x height of 8.
υ0-0-1O00X450X400. The specific gravity is also about 0.1.

C Problems to be Solved by the Invention As mentioned above, in conventional hay compression molding machines, even when compression molding is performed, punctures are large, the volume is not very small, and the specific gravity is also small. The present invention aims to minimize the bank ring of compressed hay products, and to make them into small particles and increase their density.

That is, to prevent pack rings after compression molding of hay as much as possible (in this case, all that is required is to maintain the compression molded state for as long as possible, and to tie it quickly and restrain it with the force of the string. In addition to holding the compression molded product for a long time, the pack ring can be minimized by making it possible to quickly bind the product.
+. A high-density compression and bundling method for hay, which reduces the volume and density to a specific gravity of around 0.9, reduces packaging and transportation costs, and prevents the load from collapsing, and the equipment used therein. is intended to provide.

Arrangement of the Invention (a) Means for Solving the Problems The method according to the present invention provides a final compression chamber (1) of a hay compression molding machine.
) The compression-molded product (2) is compressed and held by pushing it into the cartridge chamber (3), which has an internal structure that does not allow it to expand, and has a binding paper 1.5) wrapped around the inlet 4). At the same time, the string (5) is wound around the circumference, and after binding in that state, the compression molded product (2) is extruded by the force when the next compression molded product (2) is sent into the cartridge chamber (3). It was designed so that

In addition, the apparatus used for carrying out the method of the present invention is provided with a cartridge chamber (3) for holding compression and bundling in front of the final compression chamber (1) of the hay compression molding machine, and a cartridge chamber (3) for holding compression and bundling.
A shilling (1) for extruding the compression molded product (2) is placed behind the
4), and a tapered inner surface (8) that becomes narrower in the direction in which the compression molded product (2) is pushed inside the cartridge chamber (3).
), and a non-return protrusion (9) is formed on the inner surface near the entrance (4) of the electric warning (3).

In the above configuration, the final compression chamber f1+ is a chamber in which hay is finally compressed through primary, secondary, etc. compression in the hay compression molding machine. The compression chamber (1) is box-shaped and has openings (6) at the front and rear so that the inside can be compressed from the front and rear.

The cartridge chamber (3) has a box shape with an inlet (4) at the rear facing the front opening (6) of the compression chamber t1) and an outlet (7) at the front. Also cartridge chamber (3)
A structure in which the inside of the compression molded product (2) does not expand means that the cartridge chamber (3) is moved in the direction in which the compression molded product (2) is pushed;
That is, the inner surface (8) is tapered to become narrower from the inlet (4) to the outlet (7), and the inner surface near the inlet (4) is designed to prevent the pressed compression molded product (2) from expanding and protruding. A check protrusion (:9) is formed to prevent this. Note that the degree of the taper is, for example, 200 cm in depth,
When the height of the inlet (4) is 186 m1n, the outlet (7)
It is sufficient that the height is 182 mm.

As a means for hanging the binding paper (5) over the entrance +41 of the cartridge chamber (3), for example, in the case where the cartridge chamber (3) is opened with a hinge as shown in Figs. 7 and 8, a string (
5) may be hung by hand, but if the cartridge chamber (3) is a fixed type as shown in Fig. 10, a string hanging rod (12) should be used between the electric training (3) and the cartridge chamber mounting plate (11). round trip aJ
Alternatively, the cord (5) may be passed around the cord (5). (13) is a string bobbin.

As a means of binding the string (6), or in the case where the cartridge chamber (3) is opened as described above, it is also possible to tie the string (6) by hand, for example. In the case where the cartridge chamber (3) does not open, the string (I2) is moved upward by the reciprocating movement of the string hook (I2).
5) All you have to do is tie them together and bind them together.

The means for taking out the compression molded product (2) bound with strings (5) from the cartridge chamber (3) is to push out the compression molded product (2) that has been compressed there to the rear of the final compression chamber (1). A shilling (14) is provided. This cylinder (14) pushes the next compression molded product (2) into the cartridge chamber t3).
When K is fed into the cartridge chamber (3
) is made to extrude the bundled compression molded product (2).

In FIG. 9, (15) is a groove for securing the string, which is formed by forming the tapered inner surface (8) K of the cartridge chamber (3). ) seems to easily extend forward along with it? It has been done.

The final compression chamber (1), the cartridge chamber (3), and the extrusion cylinder (14) may be positioned on the same center line, but the compression molded product (2) after bundling is To facilitate the operation, the final compression chamber t++ may be made laterally movable, and a cylinder (I4) and a cartridge chamber (3) may be provided correspondingly.

In the figure, (+6!) is the locking metal fitting of the cartridge chamber (3), (+7) is the strap holder, and (18) is the grip part of the cartridge chamber (3).

b. Function The operating state of the present invention is as follows. That is, the hay undergoes primary and secondary compression, and is finally compressed in the final compression chamber (1), but if it is taken out immediately, the pack ring will be large due to expansion due to the restoring force. Therefore, in the present invention, the compression molded product (2) that has undergone compression in the final compression chamber (11) is pushed into the cartridge chamber (3), which has an internal structure in which it does not expand, as shown in FIGS. 1 to 5. Then, the material is held at a pressure of J6i fi, bound, and extruded.

The internal structure of this cartridge chamber (3) is a tapered inner surface (8) that becomes narrower in the pushing direction as described above, and an inlet (4).
A non-return protrusion (9) is provided on the inner surface in the vicinity. Therefore, the pressed compression molded product (2) is placed at the exit (7) as shown in Figure 3.
The compressed state is maintained without expanding in the direction of the inlet (4). At the same time, the compression molded product (2) is inserted into the cartridge chamber (
3), the entrance (4) is inserted in advance as shown in Figure 1.
), so as shown in Fig. 2, the compression molded product (2) should be hooked with the tie (5) on the front, and the string (5) should be pulled on the top and bottom. while being sent deep inside.

Therefore, the string (5) is automatically wrapped around the compression molded product (2) from the front side to both upper and lower surfaces, as is clear from FIG. At this time, the presence of the groove (15) makes it easier for the string (5) to stretch.

Therefore, next, the compression molded product (2) is placed in the cartridge chamber (3).
While compressed and held at I41 in Fig. 4, tie the string (5). This binding work is performed in the cartridge chamber (
You can open the cartridge chamber (3) and tie it by hand.
) may be tied by reciprocating movement of the strapping rod (I2) that opens the strings. In any case, with this binding, the compression molded product (2
) comes out of the cartridge chamber (3) & is held compressed and restrained by the string (5).

Thereafter, this compression molded product (2) undergoes the final compression in the final compression chamber fll, and the next pressure I#i molded product (2) is extruded by the cylinder (14) as shown in FIG. 5 into the cartridge chamber. (
3), the force causes the cartridge chamber (3)
) is extruded from. In other words, the cartridge chamber (3)
The compression molded product (2) that was compressed and tied inside is
It will remain in the cartridge chamber (3) as it is until the next pressure &, i It-shaped object (2) is extruded.

Therefore, the compression-molded product (2) as shown in FIG. 6 thus obtained is compressed into as long a poem as possible in the cartridge chamber (3), and tied in that state with a string. Expansion due to restoring force, that is, puncture, almost no longer occurs.

C. Effects of the Invention As is clear from the above, according to the present invention, the compression molded product that has been compressed in the final compression chamber is not recovered as is. It has an internal structure that does not expand, and by pushing it into a cartridge chamber with a binding string wrapped around the entrance, the compression molded product is wrapped with a string and compressed. The compression molded product is extruded by the incoming force.

Therefore, compared to the conventional method of taking out the compression molded product immediately from the final compression chamber of the compression molding machine, the compression molded product is kept compressed for a longer time, and the expansion of the compression molded product is restrained by binding in that state. Therefore, the amount of banking can be minimized. For example, conventional compression molded products usually have a width x depth x height of 80 mm.
0~1000X450X400++++++++, specific gravity 0.
According to the present invention, the size of 200~220×20
0x400, the volume can be reduced and the density can be increased to about 0.9.

Therefore, the present invention has the advantageous effects of being able to reduce packing and transportation costs and preventing cargo from collapsing.
