Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a spreading machine for feeding a cloth (cloth material) wound in a roll shape by a required length and cutting or folding the material.

Conventional technology This type of conventional spreading machine reciprocates back and forth, causing the fabric fed from the front end of the fabric spreading machine to wavy due to the wind pressure when the fabric spreading machine moves, and the tips of the spread fabric do not align. However, there is a problem that wrinkles occur in the stretched fabric. Therefore, in order to deal with such a problem, a windshield curtain is provided at the front end of the fabric spreading machine so as to be located inside the fabric that hangs downward to prevent waving of the fabric due to wind pressure when the fabric spreading machine is moved. Things are known.

Problem to be solved by the invention As described above, when the windshield curtain is provided at the front end of the fabric spreading machine to prevent the waving of the fabric due to the wind pressure when the fabric spreading machine is moved,
The wind pressure applied to the fabric from the front when the fabric is moved forward is received by the wind pressure curtain, and the wind pressure when the fabric is moved backward is blocked by the windshield curtain. Since there is a movable part such as a pitcher in the lower part of the front end, it is impossible to install the lower end of the windshield curtain up to the moving table of the spreading machine, and there is a gap, and the rear end of the spreading machine is large. Is open,
Air flows between the rear end opening and the front end opening. In particular, when the retraction machine moves backward, the air flows at an increased velocity from the large opening at the rear end to the opening with a small clearance area at the front end, forming turbulence at the clearance outlet, and this turbulence acts as a windshield curtain. There is a problem that it gets into the space between the cloth and the cloth becomes large and wrinkles occur.

The present invention solves such a problem, and reduces the flow of air between the rear end and the front end of the re-spreading machine, and prevents swelling and wrinkling of the fabric. The purpose is.

Means for Solving the Problem In order to solve this problem, according to the present invention, a cloth receiving device is provided at the rear end side on the main body of a reciprocating machine that can be reciprocated back and forth on a table, and the cloth receiving device is provided at the front end side. A feeding device is provided for feeding the cloth pulled out of the cloth on the device downward, and windshield curtains are provided at the front end and the rear end of the main body of the spreading machine.

Action With this configuration, the amount of air flowing between the rear end portion and the front end portion is small, and the waving of the material that hangs down on the front end portion of the retraction machine body during the retraction is prevented. In particular, the amount of air flowing from the rear end to the front end side during the backward movement of the main body of the fabric spreading machine is small, and there is almost no turbulent flow at the gap exit on the front end side. The material does not get into the gap and the fabric does not bulge significantly.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a spreader which can be moved back and forth on a moving table 2. On a main body 3 of the spreader 1, a piece receiving device 4 is provided on the rear end side, On the front end side, there is provided a feeding device 6 for feeding the cloth pulled out from the piece of material 5 on the piece of material receiving device 4 downward. 7 is a pitcher provided at the lower part of the front side of the fabric spreading machine 3, and 8 is a windshield curtain provided at the front end of the fabric spreading machine 3 at a position where the pitcher 7 does not interfere with the lower end of the windshield curtain 8. A gap is formed between the upper surface of the table 2 and the upper surface of the table 2. Further, 9 is a windshield curtain provided at the rear end portion of the rebeling machine main body 3, and is configured so that almost no gap is formed between the lower end of the windshield curtain 9 and the upper surface of the table 2.

In the above-mentioned structure, since the windshield curtains 8 and 9 are provided at both front and rear ends of the fabric spreading device 3, there is a gap at the front end, but the air flowing between the rear end and the front end. Is small, and it is possible to prevent the waving of the material that hangs down from the front end of the fabric spreading machine main body 3 at the time of spreading. In particular, the amount of air flowing from the rear end to the front end side during the backward movement of the fabric spreading machine 3 is small, and there is almost no turbulent flow at the front end side gap outlet. It does not get into the space between the fabric and the fabric does not bulge significantly.

As described above, according to the present invention, the air flow between the rear end and the front end of the main body of the retraction machine is reduced, and the air for the fabric fed from the front end of the main body of the retraction machine is reduced. The influence of the flow can be reduced, and the swelling and wrinkling of the fabric can be prevented.
