BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a catcher of a spreading device which allows a catcher body to be easily moved on a spreading table and fixed at an arbitrary position.

[0002]

2. Description of the Related Art A fabric spreading device is a device for folding a cloth wound in a roll shape into a plurality of flat layers while reciprocating on a fabric spreading table for a subsequent cutting step. Therefore, a catcher main body fixed to the spreading table is provided on one side of the spreading device main body on the spreading table, and the other side of the spreading device main body is provided with a catching width corresponding to the desired spreading width. It has a movable catcher body.

That is, two catcher bodies are required on one spreading table, one of them is fixed and the other one is movably arranged. The movable catcher body is also extended. It is necessary to fix this on the spreading table at the time of counterwork.

As shown in FIG. 4, a movable catcher body which has been generally used in the past has an L-shaped fixed plate c provided on both side frame plates b of a substantially triangular shape connected by a bar a. Then, using this fixing plate c, the clamp d
Therefore, the method of fixing to the spreading table e was adopted.

[0005]

[Problems to be Solved] The fixing plates c can be moved by disposing the clamps d on both sides of the catcher main body and releasing the clamps d. The top of e must be moved and finely adjusted according to the spread width set corresponding to the marking sheet, and when fixing after moving, the two catcher main bodies maintain an accurate parallel state. Therefore, it was necessary to fix them by using clamps d on both sides of the catcher body.

Therefore, before starting the spreading operation, the catcher body must be set while reciprocating on both sides of a wide and long spreading table e, and the catcher body is by no means light. Therefore, fine adjustment on the spreading table e was a very complicated work. Moreover, this required a relatively long time.

[0007]

Therefore, in order to solve the above-mentioned problems, the catcher of the spreading device according to the present invention is mounted on the frame plates on both sides of the catcher body with springs elastically mounted via wheels. The wheels are arranged on the plate, and the cylinder mounting plate extending to the lower surface of the side edge of the spreading table is fixed to the both side frame plates, and the cylinder whose piston rod faces the lower surface of the spreading table with respect to this cylinder mounting plate. And each cylinder is connected via a hose.

[0008]

That is, the catcher body can be moved or fixed on the spreading table by operating the cylinder, and the catcher body can be fixed, moved or slightly moved in a short time without reciprocating left and right of the spreading table. The adjustment is made possible.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a catcher for a spreading device according to the present invention will now be described with reference to the drawings. 1 is a frame plate 2 having two substantially triangular shapes connected by a plurality of bars 3 and The catcher body is basically the same as a conventionally known one in that a catching bar (not shown) is arranged and configured.

Reference numeral 4 denotes a wheel mounting plate which is elastically arranged on both side surfaces via springs 5. The wheel mounting plate 4 is formed in an L shape, and two wheels 6 are arranged on the lower surface thereof.

As means for elastically attaching the wheel mounting plate 4 to the frame plate 2, two L-shaped plates 7 are fixed to the side surface of the frame plate 2, and the L-shaped plate 7 and the wheel mounting plate 4 are fixed.
Are connected by the spring 5 as described above.

Reference numeral 8 denotes a retraction table generally used in the past, and reference numeral 9 denotes rails disposed near both side edges of the top surface of the retraction table 8. Since the rail 9 is basically for reciprocating movement of a reciprocating device (not shown), the rail 9 is arranged over the entire length of the reciprocating table 8, and therefore, in the present invention. The rail 9 is also used to move the catcher body 1. Therefore, the wheels 6 are configured to ride on the rails 9.

Numeral 10 is a cylinder mounting plate fixed to the frame plates 2 on both sides, and this cylinder mounting plate 10 has one end fixed to the frame plate 2 as described above and passes through the lower surface of the wheel mounting plate 4. Further, the cylinder mounting plate 10 is formed by bending from the side edge of the spreading table 8 to the lower side of the spreading table 8, but the cylinder mounting plate 10 is not fixed to the wheel mounting plate 4.

Reference numeral 11 is a cylinder arranged at the free end of the cylinder mounting plate 10. When mounting the cylinder 11 on the cylinder mounting plate 10, the piston rod 12 of the cylinder 11 is mounted so as to face the lower surface of the spreading table 8. I shall. Also, two cylinders 11 are arranged for one catcher body 1,
In this case, the two cylinders 11 are connected by a hose (not shown) so that the operations are synchronized.

In the above description, the rail 9 may be provided only on one upper edge of the spreading table 8 and not on the other upper edge. In this case,
The vehicle 6 on the side where the rails 9 are not arranged directly travels on the upper surface of the spreading table 6. Further, in this case, it is necessary to use a means (not shown) for eliminating lateral shake by separately disposing a wheel that comes into contact with the side surface of the spreading table 8 with respect to the cylinder mounting plate 10.

It is assumed that the cylinder 11 is operated to shorten the piston rod 12. Then, the elastic force of the spring 5 causes the catcher body 1 to slightly float above the retraction table 8, and the frame plate 2 of the catcher body 1 does not contact the retraction table 8.

Therefore, in this state, only the wheels 6 are in contact with the rails 9, so that the entire catcher body 1 can freely move along the rails 9 on the retraction table 8 in the longitudinal direction. Become.

When fixing the catcher main body 1, the cylinder 11 is operated in the opposite manner to the above, and the piston rod 12 is ejected. Then, the piston rod 12 presses the lower surface of the spreading table 8,
As a result, the cylinder mounting plate 10 is lowered as a whole, so that the frame plate 2 and thus the entire catcher body 1 is pulled down to the upper surface of the spreading table 8 against the resilience of the spring 5, and thereby the catcher body 1 is pulled down. It can be fixed to the spreading table 8. In this case, the entire catcher body 1 can be fixed at the same time by synchronizing both cylinders 11.

In this state, the spreading operation is started, but the spreading operation itself is performed by a conventionally known method.

[0020]

As described above, according to the catcher of the spreading device according to the present invention, the wheels are arranged on the wheel mounting plates elastically arranged on the both side frame plates of the catcher body through the springs, and Cylinder mounting plate that extends to the lower surface of the side edge of the spreading table is fixed to both side frame plates, and a cylinder with the piston rod facing the lower surface of the spreading table is fixed to this cylinder mounting plate, and Since they are connected via a hose,
By operating the cylinder, the catcher body can be moved or fixed on the spreading table, and the catcher body can be fixed, moved or finely adjusted in a short time without reciprocating left and right of the spreading table. It has the effect of being able to do so.
