Description

[Detailed description of the invention] (Purpose of the invention) The invention relates to improving the fabric receiver in a spreading machine.
The purpose of this is to ensure that the catcher can catch the edge of the fabric and to eliminate the occurrence of wrinkles.

(Prior Art) In a conventional fabric spreading machine equipped with a fabric cutting mechanism, the edge of the fabric fed out from the fabric spreading machine is captured by a catcher installed on a table and the fabric is spread.

The structure is shown in Fig. 4, in which a plate B is installed as a dough holder at the rear end of the frame A on both sides of the spreading machine, and the rear edge B' of the plate B is a holder C. It is supported so that it does not bend.

A dough presser D is provided above the board B of the dough receiver to press the dough zone W' onto the board B of the dough receiver.

The catcher E that catches the fabric edge W' is the spreading table F.
A large number of needles (2) are protruded from the lower surface of the throat plate G of the catcher E, and the needles (2) press against and capture the edge W' of the fabric.

This conventional fabric holder device has the following drawbacks.

In other words, since the dough support must be constructed by installing a support crosspiece C under the trailing edge B' of the plate B, the position of the trailing edge B' in the height direction is at a height relative to the top surface of the spreading table F. position.

Therefore, the needle plate G that has captured the fabric zone W' must be lowered onto the spreading table F from a high position.

When the throat plate G descends from a high position onto the spreading table F,
The captured fabric edge W' may come off the needle H, making it impossible to spread the fabric.

Furthermore, since the fabric W is pulled out onto the spreading table F from a high position, it is easily affected by wind pressure during spreading, and wrinkles may occur.

(Structure of the invention) In the present invention, the fabric holder is provided with an elastically bendable spring plate on the lower side of the plate, and the tip of the spring plate is made to protrude from the rear edge of the fabric holder plate. Examples will be described below based on the drawings.

In FIGS. 1 to 3, the dough holder plate 1, which is bent in a substantially dogleg shape at the center, is installed between frames 20 on both sides of the spreading machine, and the dough holder is placed on the upper side of the plate 1. The dough holder is provided parallel to the plate 1 so that the dough presser 3 can press the edge W' of the dough on the plate 1.

The dough presser 3 has a rotatable arm 4 with a large number of spring plates 5 protruding from it at approximately equal intervals. , or provided so as to protrude by a predetermined length from the rear edge 1a.

The embodiment shown in the drawings is the latter.

The fabric holder is on the underside of the plate 1, and the fabric holder is located at the bent part 1 of the plate 1.
A crosspiece 6 is installed on the fabric holder in parallel with the plate 1 in the vicinity of b, and the proximal end 7a of an elastically bendable spring plate 7 is fixed to the crosspiece 6. The tip portion 7b of the dough tube protrudes from the rear edge 1a of the plate 1 by a predetermined length.

Its length corresponds to the width of the throat plate 12 of the catcher 10, which will be described later.

Like the spring plates 5 of the dough presser 3, the spring plates 7 are arranged in multiple stages at predetermined intervals, and each spring plate 7 is located approximately in the middle of the adjacent spring plates 5.

At the middle part of the spring plate 7, the fabric tube is in elastic contact with the lower surface of the plate 1.

In order to adjust the elastic force of the spring plate 7, the mounting is performed using the crosspiece 6.
It is preferable that the holder is rotatably provided around the longitudinal axis and fixed at a predetermined angular position.

In addition, the tension spring 8 is rotatably mounted on the crosspiece 6.
One end may be connected, and the other end may be attached to the frame 2 so that its position can be adjusted freely.

A known catcher 10 is installed on the spreading table 9.

This catcher 10 includes a spring plate 50 of the dough presser 3.
An arm 13 protrudes from a needle plate 12 having a number of needles 11 on its lower surface corresponding to the intervals, and the arm 13 is installed on seven frames 14 set on a spreading table 9 so as to be able to rise and fall.

The upper end of a link 15 is rotatably connected to the middle of the arm 13, and the roller 16 is pivotally connected to the lower end of the link 15.

This roller 16 is provided so as to be in contact with a cam 18 whose one end is pivotally attached to a mounting plate 17 connected to the frame 2 of the spreader, and when the roller 16 moves in contact with the upper surface of the cam 18, the arm 13 is moved. Go up and down.

A recess 19 into which the roller 16 is fitted is formed at the upper edge of the cam 8.

In the state shown in the figure, the arm 13 is pushed up by the cam 18 so as not to press the fabric W already spread on the spreading table 9.

When the spreading machine further retreats in the direction of arrow Q from the position shown in FIG.
When the throat plate 12 is inserted into the recess 19 of 8, the needle plate 12 is slightly lowered to press and capture the edge W' of the fabric on the spring plate 7.

At this time, the needle plate 12 does not place the fabric tube on the plate 1, but only on the spring plate 7, so the spring plate 7 bends slightly downward due to the weight of the throat plate 12. When the needle plate 12 and the tip 7b of the spring plate I start moving forward in the horizontal direction, the positions of the needle plate 12 and the tip 7b of the spring plate I shift in the horizontal direction, so that the weight of the throat plate 12 acts more on the tip of the spring plate 7. The degree of curvature becomes steeper, and the tip 7b of the spring plate 7 and the dough edge W' approach the upper surface of the spreading table 9.

Therefore, the needle plate 12 does not suddenly fall from a predetermined height position, but its height position is gradually displaced downward, and the needle plate 12 captures the fabric edge W' from a low position and moves onto the housing spreading table 9. It becomes a downward slope.

The needle plate 12 captures the edge W' of the fabric and transfers it onto the spreading table 9 or the fabric W that has already been spread on the spreading table 9.
It descends gently upwards and holds the fabric edge W' in place.

When the spreader finishes moving forward, the cutter 20 performs cutting, and then the spreader moves backward again to repeat the above-described operation.

(Effect of idea) Since the present invention has the above-described configuration, it has the following advantages.

Since the fabric tube does not require a support unit to be provided below the trailing edge of the plate, the fabric tube can be placed at a lower position with the plate closer to the top surface of the spreading table.

In addition, when the throat plate captures the edge of the fabric on the spring plate, the spring plate further curves downward due to the weight of the throat plate, so the descending height of the throat plate and edge of the fabric is further reduced, and the needle plate Not only is the capture by the paper more reliable, but it is also less susceptible to the effects of wind pressure during spreading, eliminating the occurrence of wrinkles.
