[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding a hose used for discharging liquid such as control and cleaning.

[0002]

2. Description of the Related Art A hose winding device used for control is
As disclosed in Japanese Utility Model Laid-Open Publication No. 60-132881, the prime mover is provided with a take-up drum driven through a transmission band, and one end of a hose wound by the take-up drum so as to be drawn out is connected to a pump driven by the prime mover. It is connected to a discharge passage, and a nozzle is connected to the other end so that the hydraulic pressure generated by the pump acts on the nozzle.

[0003] In the winding device, a power from a prime mover is transmitted to a winding drum via a transmission band, and further, a tension wheel for tensioning and relaxing the transmission band, and an electric motor for operating the tension wheel. And a transmitter and a receiver for receiving a transmission signal. When pulling out the hose wound on the winding drum, an operator holding the nozzle portion of the hose operates the transmitter and transmits the hose. The electric motor is actuated via a receiver by a signal, and the tension wheel is moved in a direction in which the transmission band is relaxed to allow the winding drum to freely rotate and is pulled out by the power of the operator. Yes,
Further, when winding the hose, an operator holding the nozzle portion of the hose operates the transmitter, and the transmission signal indicates
By operating the electric motor via a receiver, the tension wheel is moved in a direction in which the transmission band is tightened, and the winding drum is driven to be wound and is forcibly wound.

[0004]

In the conventional hose winding device, the power transmission to the winding drum is cut off, the winding drum is rotated freely, and an operator holding the nozzle portion of the hose can cut the hose. When the hose is pulled out, the drawn hose moves along the ground.Therefore, there is a problem that the drawing load of the hose is large and the drawing workability is poor.In addition, the electric motor for the transmitter, the receiver, and the tension wheel is used. Required,
There was a problem that the cost was high.

[0005] The winding drum driven by the motor rotates at a substantially constant rotation speed, and the hose wound on the winding drum overlaps from the winding peripheral surface of the winding drum toward the outer periphery. As the winding amount increases, the diameter of the winding portion increases, and conversely, as the drawing amount of the wound hose increases, the diameter of the winding portion increases. When the hose is wound up in spite of the fact that the rotation speed of the winding drum is almost constant, the winding amount of the hose is increased and the winding amount of the hose per rotation of the winding drum is increased. The length is longer and the hose winding speed is faster. When the hose is pulled out, the length of the hose with respect to one rotation of the winding drum becomes shorter as the amount of the hose drawn out increases. Therefore, it is necessary for the worker holding the nozzle portion of the hose to increase the walking speed from the start of the winding of the hose to the end of the winding, and the walking speed from the start of the drawing of the hose to the end of the drawing. In any case, the worker holding the hose needs to change the walking speed greatly, and the workability of pulling out the hose is further deteriorated, and the workability of winding is also poor. was there.

The pressure change can be detected by the detecting means. Therefore, by a simple operation of opening and closing the nozzle a plurality of times, the motor can be accurately driven and stopped without being affected by noise, and safety can be improved.

Further, the detection means is a pressure switch for detecting a plurality of changes in hydraulic pressure when the nozzle is opened and closed a plurality of times within a predetermined time. In the present invention, since the pressure change is detected a plurality of times by using the pressure switch, it can be simply configured with one pressure switch, and the cost can be reduced.

For example, the conductor is provided near the nozzle of the hose. In this case, the maximum winding amount of the hose can be set in advance, and when the conductor is provided near the connection of the hose to the winding drum, the maximum drawing amount of the hose can be set in advance. The hose can be wound and pulled out within this set area. Therefore, it is possible to effectively prevent the nozzle from being wound around the winding drum, and it is possible to effectively prevent the hose from being pulled out excessively and the connecting portion of the hose to the winding drum from being damaged.
