That is, in the case of the cloth feeding system using the feeding roller 22 located at a position higher than the cloth conveying surface of the feed belt 1, for example, the disentangled pieces of cloth are continuously connected in advance by a sewing machine or the like in the previous step. In the case of cloth, there is no problem because the tip of the cloth may be hung on the supply roller 22 once by hand. However, every time when a cloth of cut or roll having a short dimension is put in, the leading end of the cloth has to be hung by hand on the supply roller 22 located at a position higher than the feed belt 1 each time. In particular, it was necessary to have one worker for continuous feeding, especially for unconnected cut fabric. The end of the fabric is the supply roller 22.
Since the paper falls from the feed belt 1 to the feed belt 1 at a dash, it is folded and folded on the feed belt 1, which causes problems such as folding wrinkles and dimensional variations in the fabric.

Further, in the conventional cloth folding apparatus disclosed in Japanese Patent Laid-Open No. 52-118083, that is, the cloth folding method using the arm portion 32 that reciprocally swings, the unfolded fabric as described above is used. In the case of a long cloth in which comrades are continuously connected to each other, there is no problem because the end of the cloth conveyed by the endless belt 29 may be manually guided once to the arm portion 32 of the folding means. However, when folding a cloth of cut or roll having a short size as described above, the tip of the cloth must be guided to the arm portion 32 by hand every time the cloth is folded. Similar to the above, especially for the unconnected cut cloth, it was necessary to have one worker for guiding continuously. Furthermore, since the end of the fabric has a drop from the endless belt 29 to the pedestal 33, it is pulled by the weight of the drop of the fabric while it is still on the endless belt 29, and slides down, so that it can be folded up properly until the end. It had the drawback of not having it.

At this time, the table 51 is positioned between the guide plates 32, 32 while the bracket 52 rotates about the rotary shaft 53 as a fulcrum and the stay 54 extends to be in a locked state. In this way, the leading end of the cloth is pulled out from the trimming cloth C placed on the table 51 in the horizontal state between the guide plates 32, 32, as shown in FIG.
As shown in FIG. 5, the cloth is set on the conveyor belt 11 via the slide plate 21.

As described above, the cloth set via the sliding plate 21 is sandwiched between the nip roller 22 and the conveying roller 12 on the conveying belt 11 and moved in the conveying direction (the direction of the arrow in the figure). As described above, after being subjected to a predetermined shrinking process through a steam injection means, a cooling means, etc., which are not shown,
It will be folded as described below. It is needless to say that the operations of various devices and means are performed in the opposite direction to the above.

The cloth feeding device of the above-mentioned trousers is provided with a cloth feeding means which will be described later. Next, the feeding means will be described.

<Embodiment Example of Cloth Supplying Means> FIG. 8 shows the structure of the cloth supplying means, and is a vertical sectional front view showing the nip roller driving portion. FIG. 9 shows the vicinity of the nip roller by the cloth supplying means. FIG. 10 is a schematic side view showing the time of detecting the cloth ridge high position, and FIG. 10 is a schematic side view showing the time of detecting the cloth bulge lower part in the vicinity of the nip roller by the cloth feeding means.
8 to 10, similarly to the above, 2 is an upper side frame, 11 is a conveyor belt, 12 is a conveyor roller, 21 is a sliding member (sliding plate), 22 is a nip roller, and 23 is an arm. , 28 is a bearing, 61 is an electromagnetic clutch, 62 is a conveying roller gear, 63 is a nip roller gear, 64 is a cloth loosening member (cloth loosening plate), 65
Is a support portion, 66 is a cloth detection arm, and 67 is a detection means (photosensor).

That is, a bearing 27 for rotatably supporting the shaft of the end of the nip roller 22 is attached to the tip of the arm 23, and the upper side frame 2 has a bearing 27.
Bearing 2 for rotatably supporting the shaft portion at the end of the transport roller 12
8 is attached. Then, as shown in FIG.
An electromagnetic clutch 61 is integrally mounted on the shaft portion at the end of the transport roller 12, and a transport roller gear 62 is rotatably mounted. The electromagnetic clutch 6
The reference numeral 1 enables the transport roller gear 62 to be fixed to the transport roller 12. A nip roller gear 63 is fixed on the shaft portion at the end of the nip roller 22, and the nip roller gear 63 meshes with the transport roller gear 62. Here, the nip roller gear 63 is set to be faster than the feed speed of the transport roller 12 by the gear ratio with the transport roller gear 62.

Further, at the tip of the arm 23, as shown in FIGS. 9 and 10, a side view as a cloth slackening member for causing a swelling of the cloth due to the supercharging cloth between the arm 23 and the nip roller 22. An L-shaped cloth slack plate 64 is attached. A support portion 65 having a rotation axis of a cloth detection arm 66 is integrally attached to the cloth slack plate 64. The cloth detection arm 66 is connected to the nip roller 2
It rotates in accordance with the ridge of the cloth generated between the cloth slack plate 64 and the cloth slack plate 64, and can take a high position as shown in FIG. 9 and a low position as shown in FIG. Further, a photo sensor 67, which is a detection unit that detects the high position and the low position of the uplift of the cloth according to the rotational position of the cloth detection arm 66, is integrally attached to the support portion 65.

The operation of the cloth feeding means having the above construction will be described below. First, the nip roller 22 and the cloth slack plate 64
When there is no ridge of the cloth between the cloth and the cloth, the cloth detecting arm 66 is rotated around the rotation axis, and its tip is at the lower end position.
The photo sensor 67 detects the cloth detection arm 66,
The electromagnetic clutch 61 is operated. When the electromagnetic clutch 61 is activated, the transport roller gear 62 integrally rotates with the transport roller 12. Since the nip roller gear 63 meshes with the transport roller gear 62, the nip roller 22 is rotationally driven. At this time, the nip roller gear 63
Is based on the gear ratio with the transport roller gear 62.
Since the feeding speed is set to be higher than 2, the cloth is fed by the nip roller 22 more than it is fed on the conveyor belt 11, and the slack is raised between the nip roller 22 and the cloth slack plate 64. The slack of the fabric continues to grow while the nip roller 22 is rotationally driven.

The ridge of such a cloth is shown in FIG.
When the height rises, the cloth detection arm 66 rotates in the clockwise direction in the drawing due to the protrusion H, and the rotation of the tip end thereof is detected by the photo sensor 67. The electromagnetic clutch 61 is released by the detection of the photo sensor 67. When the electromagnetic clutch 61 is released, the transport roller 12
Since the rotation of No. is not transmitted to the nip roller gear 63, the nip roller 22 only rotates with the feeding of the fabric on the conveyor belt 11.

After that, when the fed cloth is shrunk and contracts, the rise of the cloth between the nip roller 22 and the cloth slack plate 64 becomes low as indicated by h in FIG. The cloth detection arm 66 rotates counterclockwise in the drawing, and the rotation of the tip portion thereof is detected by the photo sensor 67. As a result, as described above, the electromagnetic clutch 61 operates and the transport roller gear 62
The nip roller 22 is rotationally driven through the meshing of the nip roller gear 63. After that, such a feeding operation (by the switching control of the uniform speed feeding rotation and the supercharging rotation of the nip roller 22) is repeated.

According to the cloth feeding apparatus of the above embodiment, the effects listed below can be exhibited. (1) The leading edge of the cloth is fed to the conveyor belt 11 and the nip roller 22.
Since it is sandwiched between, it is possible to send in any form of fabric. This also eliminates the work of joining the folding anti-comrades. (2) The leading edge of the cloth is attached to the conveyor belt 11 and the nip roller 22.
Since all the pieces of cloth are placed at a position lower than that of the conveyor belt 11, the ends of the pieces of cloth do not fall onto the conveyor belt 11 and overlap with each other. (3) Since it is possible to place all pieces of cloth in a low place, by installing these devices compactly, the work of introducing the cloth becomes a work in a low place from the front, and it is possible to greatly improve the work. It was

(4) The pressing force of the cloth against the conveyor belt 11 is obtained by the operating pressure of the cylinder 25. The minimum operating pressure of the cylinder 25 and the nip roller 22 and the arm 23 are used.
It is difficult to reduce the pressing force to zero due to its own weight.
However, a suitable spring 26 that produces more than these forces
It is possible to reduce the pressing force to 0 by acting in the opposite direction. This makes it possible to handle materials that are easily affected by the pressing force.

(5) When the roll A is set at a fixed position of the machine, the bar 31 passed through the roll A can be set at a proper position simply by roughly placing it on the guide plate 32.

(6) When the winding web A is fed by the conveyor belt 11, the winding web A rotates between itself and the bar 31, and the bar 3 is rotated.
1 rotates on the rollers 34, 34 so that the bar 31
Rotate with. This rotation is more than the amount that the fabric is fed, and the winding fabric A is unwound. In order to prevent this, the roller 41 is pressed against the winding web A by a spring 43 having an appropriate output, and the roller 3 is controlled to control the rotation of the bar 31.
By adjusting the effect of the brake 35 on the roll 4, the rotation of the winding web A can be controlled. It should be noted that if the bar 31 and the roller 41 do not rotate from the beginning, or if the bar 31 and the roller 41 are set to require a rotating force, the pressing force of the nip roller 22 is required, which is not suitable for a material affected by the pressing force. Further, when the pressing force of the roller 41 is not required, the slide device 42 may be retracted and held by the magnet attraction type stopper means 47.

(7) When controlling the rotation of the winding web A, a large force is required when the winding web A is thick, and a smaller force is sufficient as the winding web A becomes thinner. The spring 26, which serves as the pressing force of the roller 41 for that purpose, has a large force when the winding web A is thick and becomes a small force as the winding web A becomes thin, and the pressing force to the winding web A is well controlled.

(8) Wrinkles and folds are eliminated and prevented by passing the two bars 31 and the rollers 41 through the S-shape before guiding the folded back B to the conveyor belt 11. (9) Bar 31 and roller 41 used when the folding anti-B is inserted
Can be easily set, so setup can be easily changed.

(10) The table 51 used in the case of the cut-back C can be rotated and stored at the feet, and the stay 54 for holding the table 51 horizontally has a lock and release function, so that the setup can be changed. It is easy to do and is designed so that it does not get in the way.

(11) Wrinkles and breaks in the cloth can be eliminated by sliding the cloth on the slide plate 21 immediately before the cloth is sandwiched between the conveyor belt 11 and the nip roller 22.

(12) By providing an appropriate amount of slack on the conveyor belt 11 before the cloth is compressed, it is possible to supply the cloth that compensates for the shrinkage of the cloth due to the compression without applying tension. (13) By installing the cloth slack plate 64 for keeping the ridge of the cloth due to the supercharging cloth in front of the shrinking step, the arm 23 can be secured only by opening the arm 23 at the time of inserting the cloth.

That is, when the shape of the cloth pedestal is flat, for example, as shown in FIG. 20, the folds on both sides of the cloth bulge as the number of folds of the cloth increases, so that the bulged portions on both sides are inward. And the center part collapses. However, the middle and high cloth stand 8
By setting the number to 9, for example, as shown in FIG. 21, even if the number of folds of the fabric increases, the folds bulge at the lower portions on both sides of the fold, and the bulges overlap. However, it will not easily collapse inside.

(3) Hopper 8 used for a long piece of cloth
It is possible to reverse 4 and 84, and use the back side of the cloth receiving base 89 for short lengths and trimming, and to easily reverse and position the cloth receiving base 89. (4) Since the point where the front end of the fabric falls from the conveyor belt 11 is inside the hoppers 84, 84 and the cloth receiving base 89, it is not necessary to manually guide the front end of the fabric each time.

In the above embodiment, the drive source for reciprocating the hoppers 84, 84 and the support plate 81 of the cloth receiving base 89 to shake off the cloth is used as the conveyor belt 1.
However, the present invention is not limited to this, and a drive source dedicated to the cloth swing-off may be used. Further, it goes without saying that other specific detailed structures can be appropriately changed.
