DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to suspending cloth by a retainer provided above a front end of the conveying surface to put the cloth on the conveying surface in an unfolded state. Free
The present invention relates to a cloth feeding device that injects air onto one surface thereof and causes the air to fall onto a conveying surface.

2. Description of the Related Art In a series of work steps such as washing, dehydrating, drying or folding sheets, wrappings, and other cloths, the cloths are developed and put into a fixed shape on a conveying upper surface. This is very important. A charging device for this purpose is conventionally known, and cloths are suspended by a worker on a holder (also referred to as a clamper or the like) provided on the front end of the transporting means. At the tip of the cloth suspended by the cage, an air nozzle is sprayed on one side and thrown onto the transport surface, but at the same time, the space on the transport surface is set to a negative pressure area, and the distal end of the cloth is transported. It is designed to be sucked onto the surface.

[0003] However, the cloth suspended by the retainer falls when released for loading, and the amount of the drop depends on conditions such as the weight of the cloth. To do so, it is necessary to adjust the flow rate and strength of the air injected from the nozzles, the injection timing, and the like according to the conditions of the cloth. However, when combined with a light cloth, the tip does not stretch sufficiently due to the excessive drop when converted to a heavy cloth, and when combined with a heavy cloth, wrinkles occur because the fall is too small compared to a light cloth. This causes a problem that it easily becomes bent or bent. Such drawbacks and problems are common to the throwing-in device that suspends the cloth and then drops it onto the conveying surface, and there is room for improvement. However, this type of device also has the advantage of ease of construction and handling.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to hold cloth properly without being affected by conditions such as weight. The tip of the cloth should hardly fall even if it is released from the cage, so that the tip of the cloth can be accurately put into the predetermined position on the transport surface regardless of the change in the conditions of the cloth. It is.
