  In FIG. 1, the cylinder member 21 is driven by the driving member 70 to reciprocate the piston portion 23, and the shower pipe 1 reciprocates through a pipe holder 55 attached to the tip of the piston portion 23. Specifically, in FIG. 17, the upper rail 61 attached to the shower pipe 1 moves horizontally with respect to the lower rail 62 together with the shower pipe 1 via the roller 64. In FIG. 17A, the moved shower pipe 1 reaches the extreme end position of the front (left side in FIG. 17), and the rear (the right side in FIG. 17) whose moving direction is opposite to the front (left side in FIG. 17). At the moment of changing to, the upper rail 61 is stopped together with the shower pipe 1. At this time, the rear end (right side in FIG. 17) of the stopped upper rail 61 is substantially aligned with the rear end (right side in FIG. 17) of the lower rail 62. In FIG. 17B, the moment when the shower pipe 1 that has moved rearward (rightward in FIG. 17) reaches the rearmost end position (rightward in FIG. 17) and the moving direction changes forward (leftward in FIG. 17). The upper rail 61 is stopped together with the shower pipe 1. At this time, the front end (left side in FIG. 17) of the stopped upper rail 61 is substantially aligned with the front end (left side in FIG. 17) of the lower rail 62. This operation is repeated by the reciprocation of the shower pipe 1, and the lower rail 62 is always shielded by the upper rail 62.

  In FIG. 1, when the shower pipe 1 is bent by its own weight or the weight of the wash water flowing inside, and when it vibrates up and down by its reaction, the cylinder member 21 connected to the shower pipe 1 by the pipe holder 55 is hinged. The portion 40 is inclined according to the bending of the shower pipe 1. That is, since the cylinder body 22 is attached to the hinge holder 34 of the cylinder support member 30, the cylinder member 21 rotates (tilts) around the pin member 41 with respect to the hinge support 32 together with the hinge holder 34. )

  When the shower pipe 1 reciprocates, the speed and stroke of the cylinder member 21 are arbitrarily changed by the driving member 70, and the speed and range of the shower pipe 1 reciprocating change. When the movement of the shower pipe 1 is changed, in FIG. 18, the water stripes 3 are not generated at the boundaries of the respective injection ranges of the cleaning water sprayed from the adjacent nozzle portions 2, and the cleaning water is sprayed uniformly on the net 4. Is done.

  Next, effects of the shower pipe guide device 10 will be described.

  As described above, according to the present embodiment, in FIG. 17, the upper rail 61 is formed to have an overall length longer than the entire length of the lower rail 62, and the shower rail 1 is at the extreme end position during reciprocation. The length that faces is formed. With this configuration, in FIG. 17A, the shower pipe 1 reaches the frontmost (front left in FIG. 17) position, and the upper rail 61 is stopped together with the shower pipe 1. The stopped upper rail 61 is rearward (see FIG. 17). 17 right side) is substantially aligned with the rear (right side of FIG. 17) end of the lower rail 62 and covers the entire length of the lower rail 62. Further, in FIG. 17B, the shower pipe 1 moved rearward (right side of FIG. 17) reaches the rearmost (right side of FIG. 17) end position, and the upper rail 61 stops together with the shower pipe 1. The upper rail 61 has its front (left side in FIG. 17) end substantially aligned with the front (left side in FIG. 17) end of the lower rail 62 and covers the entire length of the lower rail 62. Therefore, the lower rail 62 is always shielded by the upper rail 62, preventing water from entering and keeping the shower pipe 1 moving smoothly.

  Moreover, since the lower rail 62 is always shielded by the upper rail 62 by the above configuration, it is not necessary to store the reciprocating guide device 60 in a cover or the like.

  According to the present embodiment, the hinge part 40 is formed by attaching the pin member 41 to the hinge first opening part 33 and the hinge second opening part 35 having the aligned axes. Since the cylinder body 22 is attached to the hinge holder 34 of the cylinder support member 30, the hinge 40 rotates the cylinder member 21 around the pin member 41 with respect to the hinge support 32 together with the hinge holder 34 ( Tilt). With this configuration, when the shower pipe 1 bends due to its own weight or the weight of the washing water flowing inside, or when it vibrates up and down due to its reaction, the cylinder member 21 connected to the shower pipe 1 by the pipe holder 55 is hinged. The portion 40 is inclined according to the bending of the shower pipe 1. Therefore, the load on the cylinder member 21 due to bending is reduced.

  According to this embodiment, the drive member 70 changes the speed and stroke of the cylinder member 21 arbitrarily, and the speed and range at which the shower pipe 1 reciprocates. With this configuration, in FIG. 18, the water stripes 3 are not generated at the boundaries of the respective spray ranges of the wash water ejected from the adjacent nozzle portions 2, and the wash water is uniformly sprayed onto the net 4. Therefore, it is possible to prolong the life by uniformly cleaning the paper machine net and the like.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
