Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a sliding type shower device in which high pressure water is ejected while reciprocally sliding a shower pipe in a pipe axis direction, and particularly, the shower pipe is supported by a roller. The present invention relates to improvement of pipe supporting means for smoothing reciprocal sliding.

2. Description of the Related Art For example, in a paper band washing device in a paper machine, a shower pipe provided with a large number of high-pressure water jet nozzles in the axial direction is installed in the paper width direction of the paper band, and this is reciprocatingly driven in the pipe axial direction. High pressure water sent from a high pressure water supply hose connected to one end of the shower pipe is ejected while repeatedly sliding back and forth.
As shown in No. 61, the shower pipe is supported by rollers so as to smoothly slide back and forth.

The above shower device is subjected to extremely severe operating conditions in which it repeatedly slides back and forth over the years without stopping during the operation of the paper machine.

The above-mentioned rolling roller is useful for smoothing the reciprocating sliding of the shower pipe, but there is a possibility that the rotating shaft may be tilted when abrasion progresses due to long-term use. When the rollers are tilted, rolling resistance becomes large, and the smoothness of the sliding movement of the shower pipe is impaired. As a result, an overload is applied to the drive device, which causes a failure, resulting in a reduction in the useful life of the shower device.

The present invention aims to solve the above problems.

Means for Solving the Problems As a means for solving the problems, the present invention is configured such that the shower pipe is supported by a plurality of rolling rollers and that the rollers are linked by a link to integrally guide the reciprocating sliding movement. Is.

Effect According to the present invention, the rolling rollers are connected by the link while smoothly rolling the shower pipe reciprocally while rolling together as a plurality of rolling rollers connected by the link. Since the shower pipe is supported at multiple points, the rollers are forced by the pipe axis of the shower pipe via the link, effectively preventing the rolling roller from tilting during operation, and eliminating the driving failure caused by this. However, the shower device can be operated soundly and stably for a long period of time.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

Reference numeral 1 is a shower pipe having high-pressure water jet nozzles 2 arranged at intervals in the pipe axis direction, and 3 is a drive unit for applying a reciprocating sliding force to the shower pipe 1. The reciprocating drive unit 3 uses, for example, a mechanism 5 that converts the rotational movement of the motor 4 into a reciprocating movement. For example, when a screw shaft having a reciprocating spiral groove is rotated by the motor 4 and a moving piece is slid into the reciprocating spiral groove, the moving piece moves in the axial direction of the shaft due to the guiding action of the reciprocating spiral groove as the screw shaft rotates. Move back and forth. By connecting the shower pipe 1 to the moving piece side, the reciprocating motion of the pipe 1 can be taken out. Other than using a screw shaft, other reciprocating cam mechanism, crank mechanism, etc. can be adopted.

Reference numeral 6 denotes a connecting portion for transmitting the reciprocating movement of the reciprocating driving portion 3 to the shower pipe 1.

Thus, while the shower pipe 1 is repeatedly slid back and forth by the reciprocating drive unit 3, high-pressure water is sent to the pipe from a water supply hose (not shown) connected to one end of the pipe, and the high pressure water is fed from the nozzle 2 to the target object. For example, it is jetted and washed on the papermaking belt 7 in the papermaking machine.

The shower pipe 1 is supported by the rollers 8 as a means for smoothly reciprocating the shower pipe 1.

The rollers 8 are set as one set, for example, two sets, and both rollers 8 are rotatably connected by a link 9 at the end of the rotation shaft to be integrated.

Preferably, the left and right shaft ends 12a of a pair of rollers are connected by a pair of links 9.

The link connecting rollers 8 are arranged at one end and the other end of the shower pipe 1, the lower surface of the pipe is supported, and each set of link connecting rollers 8 is housed in a casing 10, and both ends of the shower pipe are inserted into and removed from the casing 10. It is inserted as much as possible, and the above-mentioned pipe support is performed in the casing 10.

One casing 10 is fixed to the outer fixed surface of the drive unit 3, and the other casing 10 is fixed to the bracket 14 integrally with the frame.

The link connecting rollers 8 of each set support the shower pipe 1 at multiple points in the axial direction of the pipe while keeping the mutual spacing constant by the links 9, and follow the reciprocal sliding movement of the pipe 1 to cause the bottom plate of the casing 10 to move. The rolling surface 11 is used as a unit and reciprocates integrally while rotating in the forward and reverse directions. Therefore, the casing 10 functions as a roller rolling means while functioning as a roller accommodating means.

2 to 4 show that the shaft 1 is formed by inserting the shaft 12 into each roller 8.
The roller 8 is rotatably supported with respect to 2, and both shaft end portions 1
2a is fitted into the mounting holes 13 provided in the left and right links 9, and the welding 1
5 or by caulking or the like. As described above, the left and right links 9 are rigidly connected by using the plurality of shafts 12 as a medium to form an integrally rigid structure, and the rollers 8 are rotatably supported by the link structure.

In this way, the shower pipe 1 smoothly slides back and forth while being guided by the link connecting rollers 8 and enables stable continuous operation for a long period of time.

Effect of the Invention As described in detail above, according to the present invention, a plurality of rollers support the shower pipe along the pipe axis at a plurality of points and are linked by a link and roll together, so that the rollers can be linked via a link. The posture of the shower pipe is corrected by the axis of the shower pipe, and the problem of tilting during operation is effectively solved, the problem that the roller tilts as in the past and increases sliding resistance and lacks smoothness in reciprocating sliding, the roller is early The present invention eliminates problems such as loss of power and excessive load on the drive device, which causes a failure, which extends the useful life of the sliding shower device and ensures stable and smooth operation over the years.
