Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spreading machine cutting device which is capable of cutting cloth fed from a spreading machine body in the width direction near both reciprocating traveling ends of the spreading machine body.

[Prior art]

Generally, a cloth revolving machine main body that removably supports a cloth wound in a roll shape and reciprocally travels on the cloth spreading base on the cloth spreading base from the cloth, and is mounted on the main body. A spreading machine equipped with a cutting device that cuts in a width direction the cloth fed on a spreading table is used. In such a spreading machine, catcher devices are provided at both ends of the set length section on the spreading table, and the folding and stacking is performed by folding back and stacking the fabric at both the reciprocating traveling ends of the spreading machine body. The dough is fed only when the machine body travels forward, the fabric is cut by the cutting device at the forward travel end, and there is a cutting and spreading cloth that is not fed out when the machine body returns to travel,
Depending on the material of the cloth and the like, the folded and folded one-sided cut and the one-sided cut and stretched are separately used. By the way, for example, as shown in Japanese Utility Model Laid-Open No. 55-132064, when the material fed from the main body of the spreading machine is slid on a guide plate tilted forward in the cutting device and fed out on the spreading table, cutting is performed. , It is possible to easily feed out the dough to an accurate position on the spreading stand and cut it.

[Problems to be Solved by the Invention]

However, in the conventional cutting device as described above, the dough is smoothly delivered in the inclination direction of the guide plate, but the dough cannot be delivered in the opposite direction. There is a problem that it is impossible to cut the dough fed out by the section, and on the other hand, only cutting and spreading can be performed, and the spreading work efficiency is not good. This invention solves the above-mentioned problems, and in addition to the conventional one-sided cutting and spreading, enables double-cutting and folding-back spreading without a washer portion, and the spreading work with good work efficiency depending on the material of the cloth. It is an object of the present invention to provide a cutting device for a spreading machine capable of

[Means for Solving the Problems]

This invention is a spreading machine main body that reciprocally travels on the spreading table while unwinding the cloth from a piece of cloth wound in a roll on the spreading table, and is mounted on this main body and is fed onto the spreading table. In a spreader equipped with a cutting device for cutting the woven fabric in the width direction, the upper part of a symmetrical guide duct in which the fabric fed from the fabric spreader is inserted into the main body of the device is supported so that it can be tilted forward and backward. , A guide driving device for reversing the guide duct at both traveling ends of the reciprocating machine main body is connected to the guide duct, the drive device is installed in the main body of the apparatus, and a lower side of the guide duct in the main body of the apparatus is connected. A blade that reciprocates in the left-right direction is provided in the.

[Action]

In the cutting device for a spreader according to the present invention, the guide duct is tilted forward, and the cloth fed from the spreader main body is inserted into the guide duct, and the spreader main body is moved forward to guide the cloth into the guide duct. When the cutting device, along with the main body of the unwinding machine, reaches a predetermined position near the forward traveling end by sliding on the lower part of the lower part, the blade is moved left and right to guide the material into the duct. Underneath (see Figure 4a). Then, the blade is stopped at a position where it does not interfere with the cloth, and the cloth spreading machine main body is made to travel forward to the forward travel end and stopped without feeding the cloth (see FIG. 4b). Here, the reversing drive device is operated to reverse the guide duct back and forth so as to incline forward when the retraction machine body travels backward, and the cutting device is extended while the material is fed from the retraction machine body through the guide duct. Backward travel with the body (see Fig. 4c). When the main body of the spreader arrives at a predetermined position near the backward traveling end, the blade is moved to cut the cloth (see Fig. 4d). afterwards,
The fabric spreading machine main body is made to travel to the backward traveling end without being fed, and stopped, and then the guide duct is reversed again and again, and thereafter the fabric spreading operation described above is repeated to carry out double folding and folding. Therefore, according to the present invention, by inverting the guide duct back and forth at both the reciprocating traveling ends of the reciprocating machine main body, the inclination direction is supported by the portion where the cloth is on the lower side during both reciprocating traveling of the reciprocating machine main body. Can be rolled out smoothly and for this purpose, cutting the fabric near both ends of the reciprocating run,
Since it is possible to cut and fold both sides without a washer, it is efficient, and it is not necessary to use a catcher device that holds the washer at the time of folding. Furthermore, since the dough is cut in the width direction with a blade below the guide duct that is turned back and forth,
It is possible to perform automatic spreading that allows the material to be accurately stacked on the spreading table without slipping of the material after cutting. Then, after the material is cut near the forward traveling end, if the cloth reversing machine main body is made to travel backward without turning the guide duct back and forth and feeding the material, one-side cutting and spreading similar to the conventional one can be performed. You can do it.
