Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower device for ejecting high-pressure water to wash a papermaking strip while reciprocally sliding a shower pipe, and more particularly, to suppress twisting of the shower pipe to smoothly reciprocate the same. Also, the present invention relates to a shower device that is designed to perform properly.

[0002]

2. Description of the Related Art In a conventional paper band cleaning device, as shown in Japanese Patent Publication No. 61-46567, a long shower pipe provided with a large number of high-pressure water fountain nozzles in the tube axis direction is used. It is installed in the width direction, and while repeatedly sliding it back and forth by a reciprocating drive device, high pressure water is sent from a water supply hose connected to one end of the shower pipe and high pressure water is ejected from a nozzle to wash the papermaking strip.

The above-mentioned washing device is provided with a reciprocating drive shaft as a reciprocating drive source for the shower pipe, and is reciprocally driven by a shaft having a spiral groove in which the drive shaft is driven by a motor, and the shower pipe is installed in parallel with the drive shaft. The drive shaft and the shower pipe are connected by a connecting arm to transmit the reciprocating motion of the drive shaft to the shower pipe, and the lower surface of the shower pipe is supported by rolling rollers to reciprocate the pipe. The movement is smooth.

Generally, this type of washing machine is placed under extremely harsh operating conditions in which it repeatedly slides back and forth over the years without stopping during the operation of the paper machine.

[0005]

In the above-mentioned cleaning device, the lower surface of the long shower pipe is supported by rolling rollers and reciprocally slid, but it is connected to the end of the long shower pipe. The water supply hose fluctuates due to the pressure of high pressure water,
Alternatively, the driving force is applied so that the drive shaft linearly reciprocates because the shower pipe is twisted when the shower pipe reciprocally slides due to the vibration of the paper machine around the washing device. When the shower pipe twists and reciprocates while twisting, and the shower pipe twists and reciprocates repeatedly, the drive shaft is linearly reciprocated, which inevitably causes an overload on the arm that connects the two, causing repeated operation over the years. Finally, there is a problem that the connecting arms will be brittlely broken and broken when they are piled up. As a result, there is a problem that the slider screwed into the spiral groove is overloaded and is destroyed in a short time.

[0006]

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and supports the lower surface of the shower pipe through sliding means or rolling means, and at the same time, makes the partial length of the pipe on the upper surface side. The anti-twist member is arranged in parallel with the same pipe, both ends of the anti-twist member are connected to the shower pipe, and the upper surface of the anti-twist member is supported by the guide bar extending so as to cross the axis of the shower pipe. In this configuration, the shower pipe is prevented from twisting.

[0007]

According to the present invention, the twist-stop member is arranged in parallel with the shower pipe over the partial length on the upper surface side, and the guide bar is provided so as to cross the upper surface of the twist-stop member. The bar prevents the anti-twist member from tilting,
As a result, the twisting motion of the shower pipe is effectively suppressed. That is, the synergistic action of the anti-twist member and the guide bar can be expected to surely suppress the twisting motion of the shower pipe.

The sliding means or rolling means for supporting the lower surface of the shower pipe exerts the effect of smoothly performing the reciprocating sliding movement of the shower pipe while twisting by the above-mentioned anti-twist member for supporting the upper surface side of the shower pipe and the guide bar. In combination with the above-described restraining effect, that is, by the cooperation of both supporting the upper surface side and the lower surface of the shower pipe, the above-mentioned twist-preventing effect is promoted, and the shower pipe can be smoothly and properly slid back and forth.

As a result, overloading of the connecting arm and the drive shaft due to the torsional reciprocating sliding of the shower pipe as in the prior art is eliminated, and breakage of the arm and premature damage of the slider sliding in the spiral groove occur. You can definitely solve the problem.
