BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide for facing a winding belt in a roll winding machine that automatically rolls a towel or a hand towel used in a hospital or a restaurant after it is folded in two. The present invention relates to a guide in an automatic roll winding machine for towels, which automatically absorbs a change in the thickness of a plate by changing the thickness of the towel and reliably rolls the plate.

[0002]

2. Description of the Related Art A dirty towel after wiping a patient's body in a hospital or the like is washed and then wound again in a roll shape and cooled or heated for reuse.
Conventionally, such a towel roll is manually wound one by one if it has a small capacity. However, if the amount is large, the labor becomes large. Therefore, it is disclosed in Japanese Patent Publication No. 25607/1990. Such a roll winding device is adopted.

[0003]

Generally, a towel roll winding device that is adopted generally has a structure in which one end of the towel is sandwiched between an endless winding belt provided with anti-slip, a roll and a guide plate, and the winding belt is driven. It is a towel wrapped in a roll. However, in the conventional automatic towel roll winding device, the two rollers are rotatably supported by the bearing on the main body frame, the belt is stretched around this, and the guide plate is arranged opposite to this. If the towel end inserted between the winding belt and the roller is not bitten smoothly, the thickness between the guide plate that has passed the bent end of the winding belt will increase significantly, and the thickness between the belt and the guide plate will increase. There is a drawback that it may break into the machine and overload the motor or the winding belt, damage or stop the equipment.

According to the present invention, even if the thickness of the towel cloth changes, the change automatically deforms the tip of the guide plate in accordance with the towel thickness and the like to absorb the thickness and enable the optimum roll winding. The purpose is to do.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and is driven by a motor and a base provided with a guide plate for rolling a towel in cooperation with a winding belt. The upper and lower frames of the endless winding belt and the winding roller are placed up and down, and the same side edge of the base and upper frame is hinged to open and close the upper frame automatically. In a roll winding machine, a guide plate is provided on a base that vertically opposes a winding belt provided on an upper frame and collects a towel fed by this belt in a roll shape in cooperation with the winding belt. The tip is bent in an arc shape, and the tip is attached to the base as a free end with respect to the base, and the surface of the guide plate is made rough so that the cushion sheet and towel can be rolled securely. Repeatedly is referred to as subject matter that none To together.

[0006]

[Function] A cushion sheet is adhered to the surface of a guide plate which rolls a towel against the winding belt, and the tip is formed into an arc shape so as to follow the outer periphery of the endless belt end and the base is used as a free end. Since the towel cloth to be rolled is thick, the cushion sheet and the elasticity of the guide plate can cope with this, and a substantially constant winding pressure can be obtained. Also, even if the towel is not normally rolled in at the beginning of winding and the thickness becomes abnormally thick due to folding, this deformation of the free end of the guide plate absorbs this towel winding abnormality and prevents damage to the device in advance. It will be possible.
