Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth feeding device for conveying a long cloth, and more particularly to a cloth feeding device for feeding a long cloth toward a processing portion such as a sewing machine.

[0002]

2. Description of the Related Art In order to produce a large amount of cloth products, a long cloth is continuously conveyed while being subjected to various processes such as edging. That is, the long cloth is continuously conveyed in various processing machines in a long length until it is divided into products. Since this long cloth has great flexibility, the conveyance in this processing machine is generally performed by using a roller longer than the entire width of the long cloth. It is necessary to convey the long cloth by such a roller by contacting the long cloth on the surface of the roller which is rotationally driven and utilizing the frictional force between the two. -17554 publication,
Japanese Patent Publication No. 59-4155, Japanese Patent Publication No. 62-19878
As proposed in Japanese Laid-Open Patent Publication No. 2003-242242, frictional force is generated by changing the conveying direction of the long cloth in the rotationally driven roller.

Further, in order to perform various processing on a long cloth, it is necessary to convey the long cloth to a sewing machine or the like in a reliable and stable state, that is, in a state where it does not meander. The techniques disclosed in the respective publications are also problematic. Therefore, for example, as in the "edge sewing device" disclosed in Japanese Examined Patent Publication No. 59-4155, "a device for sewing a long cloth while continuously flowing it, A feed roll adapted to feed the cloth, a carriage capable of moving forward or backward in equilibrium with the feed roll, and a hemming sewing machine arranged on one side of the carriage, and the carriage is moved forward. Or, the reverse movement is controlled so as to match with the ear position of the cloth flowed from the feed roll onto the carriage, but the carriage with the edge stitching sewing machine is used to make a long cloth meandering. To move forward and backward in accordance with the above means that the structure must be considerably complicated. In particular, in the method of the above publication in which the meandering of the long cloth itself is not corrected, when the meandering of the long cloth is biased to one side, the carriage on which the sewing machine is mounted must be moved infinitely in that direction. It ends up.

Further, when a long cloth is conveyed by rollers, the number of rollers is at least two or more, but these plural rollers naturally have different rotation amounts. Must be consistent. Otherwise, the long cloth that is being conveyed will be pulled between the rollers more than necessary, or slack will occur, which will adversely affect the quality of the long cloth and prevent smooth processing with a sewing machine. Is.

In short, conveyance of a long cloth to a processing part such as a sewing machine must be carried out in a stable state without exerting an unreasonable force on the long cloth itself, and the long cloth should meander. Even so, it has been desired that the correction can be easily performed by a feeder having a simple structure as a whole.

Therefore, the present inventor has conducted various studies as to how to reliably convey a long cloth having a large flexibility to a sewing machine or the like with a simple structure. The present invention has been completed.

[0007]

SUMMARY OF THE INVENTION The present invention has been made based on the above-mentioned background, and the problem to be solved is stable feeding of a long cloth to a sewing machine in a processing machine.

It is an object of the present invention that even a long flexible cloth having a large flexibility can be surely transported to a processing portion such as a sewing machine, and it is assumed that the long cloth is long. It is an object of the present invention to provide a cloth feeding device having a simple structure that can easily cope with a situation in which the position of the cloth needs to be corrected.

And the operation of the main feeding device 30 and the conveyor belt 40 is performed by the upper and lower chains C.
1 and the front and rear chains C2 are interlocked with each other.

[0011]

The operation of the cloth feeding apparatus 200 according to the present invention constructed as described above will be described in the order of conveying the long cloth W. Before that, the cloth feeding apparatus 200 is attached to the long cloth. The operation of the entire automatic hemming machine 100, which is a cloth processing machine, will be described. In this automatic hemming machine 100, as shown in FIG.
As shown in FIG. 4, the long cloth W wound or folded is arranged on the left end side in the drawing, and the long cloth W is supplied onto the first support 11 through the transport position correcting device 20. The direct drive of this supply is performed by the drive roller 26 on the first support 11.

The long cloth W sent to the first support 11 is sent from the right side of the first support 11 in the figure toward the lower side of the base 10, and this transfer is performed by the sewing table 1 having the sewing machine 50.
3 by the cloth feeding device 200 according to the present invention provided on the left side surface and the upper surface side in the figure. And this long cloth W
Is sent toward each sewing machine 50 by the first conveyor belt 40 that constitutes the cloth feeding device 200, and the sewing machine 5
The sewing machine is sewn with 0 and then sent to the second conveyor belt 60 located on the downstream side of the sewing machine 50. A swing arm 70 is provided below the tip of the second conveyor belt 60, and the swing arm 70 swings to the left and right in FIG.
It is accumulated in the state of being folded under.

The main feeding device 30 constituting the cloth feeding device 200 includes a common drive roller 31 located at the upper end of the main feeding device 30 and two rollers located below the common driving roller 31. As shown in FIGS. 4 to 6, the drive roller 32 of FIG.
Since they are all driven to rotate, they all rotate similarly. Further, the common drive roller 31 of the main feeding device 30 is a drive wheel of the conveyor belt 40 running below the processing section of the sewing machine 50, and the drive wheel on the opposite side of the conveyor belt 40 is the common drive roller. 31
Since it is driven to rotate by the front and rear chains C2 hung on the side, as a result, the main feeding device 3 for the long cloth W
The feeding by 0 to the sewing machine 50 side and the feeding by the common drive roller 31 of the long cloth W below the sewing machine 50 are completely linked. Therefore, this cloth feeding device 20
During the conveyance of the long cloth W within 0, no unreasonable pulling or talumi occurs on the long cloth W, and the conveyance of the long cloth W is carried out in an extremely stable state.

Further, in the cloth feeding apparatus 200 of the present invention, the common driving roller 31, the driving rollers 32 on the side of the main feeding apparatus 30 and the conveyor belt 40 which compose the same.
Since the rollers supporting the opposite side of each are divided into two parts, and the front and rear chains C2 for driving the conveyor belt 40 are respectively hung on the intermediate parts thereof, each part such as the common drive roller 31 is It can rotate independently with respect to the part. This will be described below with reference to FIG.

In the embodiment described below, the common driving roller 31 and the two driving rollers 32 of the main feeding device 30 constituting the cloth feeding device 200 are interlocked and driven by the interlocking mechanism 80. First, the drive shaft 81 supporting the drive roller 32 located in the center of FIG. 6 is located below the divided portion of the drive roller 32 (right side in FIG. 6) and is fixed to the drive shaft 81. Sprocket 81
It is rotationally driven via a. Of course, the drive sprocket 81a on the drive shaft 81 is connected to a drive source (not shown) by a chain. The rotational force of the drive shaft 81 is transmitted through the clutch 82 provided at the end of the drive shaft 81 to the interlocking sprocket 83 provided at the left end in FIG.
The left part of the drive roller 32 integral with the interlocking sprocket 83 rotates independently of the right part. In other words, if the left side portion of the drive roller 32 is disconnected from the drive shaft 81 by the clutch 82, the left side portion of the drive roller 32 will not be positively rotated even if the right side portion or the like of the drive roller 32 is rotated. is there.

If the drive shaft 81 and the interlocking sprocket 83 are connected by the clutch 82, the left side portions of the common drive roller 31 located above and the drive roller 32 located at the lower end are the above-mentioned upper and lower chains C1. It is rotated by each interlocking sprocket 83 on which is mounted. As a result, the left side portions of the common drive roller 31 and the drive roller 32 at the lower end are driven by the drive roller 3 on the drive shaft 81.
Since the upper and lower chains C1 are hooked as shown in FIG. 5, they rotate in the same direction. Further, on the right end side of the left side portion of the common drive roller 31 shown in FIG. 6, an interlocking sprocket 83 for rotating the roller on which the conveyor belt 40 is hung is integrally provided. If it is rotated, the conveyor belt 40 travels through the front and rear chains C2 while interlocking with the rotation of the common drive roller 31 of the main feeding device 30.

Further, the common drive roller 31, the drive roller 32, and the rollers for the conveyor belt 40 are divided into two parts, that is, left and right parts, and the rotational drive of each part is as described above. Since they are individually and independently performed, for example, only the left side portion of the common drive roller 31 or the like can be positively rotated, and the other portions can be stopped or freed. Accordingly, when the long cloth W starts to meander, the edge portion on the side where the traveling is delayed can be positively sent out, and the cloth feeding apparatus 200 of the present invention can make the long cloth W The meandering can be corrected by correcting the position of the long cloth W itself.

Although the main feeding device 30 is used, in the main feeding device 30, each driven roller 33 is supported by releasing the engagement by the stopper 36 as shown by the phantom line in FIG. The moving plate 34 is used for each drive roller 3
It is moved to the left in the drawing while being guided by the guide member 35 with respect to the support plate 39 that supports the device 2. As a result, between each drive roller 32 and the driven roller 33,
Since the space as shown in FIG. 1 is formed, the long cloth W is passed through this space. As shown in FIG. 1, this space is sufficiently vacant in the vertical direction and has a linear shape. Therefore, the long cloth W is inserted (in this embodiment, it is inserted from the bottom to the top). Is very easy to do.

After the insertion of the long cloth W is completed as described above, if the moving plate 34 supporting the driven roller 33 is pressed against the drive roller 32 side, as shown in FIG. W is sandwiched by each drive roller 32 and driven roller 33 in a so-called corrugated state, and the stopper 36 engages with the locking pin 36a on the support plate 39 side to automatically fix the moving plate 34 to the support plate 39. Done. As a result, the long cloth W comes into close contact with the surface of the drive roller 32, and therefore, by driving each drive roller 32, the long cloth W is reliably conveyed to the sewing machine 50 side. Of. When the long cloth W is hung on the respective drive rollers in a zigzag state as in the conventional case, the rotation directions of the respective drive rollers have to be opposite to each other, which complicates the structure. However, since the driving rollers 32 need only be rotated in the same direction, the structure of the main feeding device 30 is also simplified in that sense.
