  The present invention relates to a cloth feeder and a cloth unfolding apparatus. More specifically, a cloth feeding machine for loading cloths such as washed sheets, wrapping cloth (duvet cover of two fabrics), pillow covers, towels, tablecloths, etc. into a cloth unfolding device, and the cloth. The present invention relates to a cloth unfolding apparatus provided with a kind throwing machine.

  Large quantities of sheets are used in hotels and hospitals. Used sheets are washed and ironed in a laundry factory and used again in hotels and hospitals. In a laundry factory, cloths such as sheets are washed and then ironed with a roll ironer or folded with a cloth folding device. In order to supply the cloth to these processing apparatuses, it is necessary to develop the cloth in advance. When an operator performs the work of deploying the cloth, a great amount of time and labor are required for the work. Therefore, in recent years, this work is performed using a cloth deployment device.

The cloth deployment device described in Patent Literature 1 is generally configured as follows.
When the worker attaches the corner of the rectangular cloth to the feeding chuck (attachment means), the feeding chuck moves and delivers the corner that has been gripped to the transverse chuck. By traversing the traversing chuck, the edge of the square-shaped cloth is placed on the belt conveyor in a state where the edge of the quadrangular fabric is linearly extended. The belt conveyer is driven forward to suspend the square cloth on the front of the apparatus, and the extension chuck grips both ends of the square cloth in the width direction and pulls it to suspend it. By this operation, the rectangular cloth is developed into a quadrangle. After the rectangular cloth in this state is drawn into the apparatus, it is discharged toward the subsequent processing apparatus.

  In the conventional cloth unfolding device, in order to deliver the cloth to the chuck of the next process such as the transverse chuck, the opening direction of the transverse chuck and the opening direction of the input chuck to which the worker attaches the cloth are the same direction. There is a need. Since the opening direction of the transverse chuck is substantially downward, the opening direction of the closing chuck is also substantially downward. However, since the opening direction of the input chuck is downward, it is difficult for an operator to visually recognize the front and rear positions of the input chuck, and there is a problem that it takes time for the input operation.
