DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support device for a futon, etc., which is mainly used when binding futons using a sewing machine.

[Conventional technology]

A conventional support device for supporting a futon has a structure in which a large number of clips are attached to the inner periphery of a frame provided on a support base to sandwich the side edges of the futon.

[Problem that the invention seeks to solve]

For this reason, in the conventional futon support device described above, one futon is brought into the frame, its side edges are held between clips, and after the sewing work is completed, the futon is removed from the clips and taken out from the frame. Therefore, there are problems in that it takes time and effort to put on and take off the futon, and it is not possible to bind the futons continuously.

The present invention can automatically attach and detach a flexible sheet such as a futon, send the flexible sheet under tension to a working machine such as a sewing machine body, and take out the processed flexible sheet from the working machine. It is an object of the present invention to provide a support device capable of continuously feeding a long flexible sheet to a working machine for processing.

[Problem that the invention seeks to solve]

In order to achieve the above object, the present invention provides a pair of left and right endless transport bodies each having a plurality of clips for holding the side edges of a flexible sheet such as a futon, and moving the conveyor body forward and backward with the clips facing inward. a first opening/closing mechanism that is movably provided and closes each clip in sequence to sandwich the side edge of the flexible sheet when the clip enters the feeding surface of the working machine near the folded end on the inlet side of the pair of transfer bodies; A second opening/closing mechanism is provided near the folded end on the exit side of the pair of transfer bodies to sequentially open each clip when the clips are retracted from the feed surface, and a second opening and closing mechanism is provided on the feed surface of the transfer body. After the clips have clamped the side edges of the flexible sheet, a guide rail is provided to move the clips outward in the width direction of the flexible sheet and tension the flexible sheet.

[Effect]

Attach the front end of a flexible sheet such as a futon to the closest left and right clips, and attach the left and right endless conveyors to the feeding surface (sewing surface) of a working machine such as a sewing machine.
While moving the clips forward, after the clips enter the feed surface of the working machine, each clip is sequentially closed by the first opening/closing mechanism. Due to the above operation, the flexible sheet is grabbed by the clips on both sides and carried into the working machine. At this time, the pair of left and right transport bodies move while being guided by the guide rails, and the flexible sheet such as a futon is moved. Pull it outward in the width direction to create appropriate tension. In this state, the circulation of the transport body is temporarily stopped and a working machine such as a sewing machine main body is operated to process the flexible sheet such as the futon. After the processing is completed, the flexible sheet is moved together with the transport body, and when the clip is retracted from the feeding surface of the working machine, the clips are sequentially opened by the second opening/closing mechanism to release the flexible sheet.

In addition, when sewing futons or the like continuously, the main body of the sewing machine is operated while the transfer body continues to circulate and move the futons without stopping.
