Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a support device for a shower pipe that is connected to a reciprocating drive device and repeats reciprocating motion while spouting cleaning liquid.

(Prior Art) Conventionally, the most commonly used support device for this type of shower pipe is one in which the pipe is supported by a shaft-supported roller.

(Problem to be solved by the invention) Due to its structure, the shower pipe support device using the shaft-supported rollers cannot be wetted with cleaning liquid, regardless of whether the bearings supporting the shafts at both ends of the rollers are pole bearings or not. Otherwise, foreign matter may enter the sliding surface, resulting in poor movement and abrasion between the pipe and rollers. In the case of shower pipes that work constantly to wash nets and felts, such as those used in paper factories, there is a problem that not only the lifespan of the bearings but also the lifespan of the reciprocating drive device is shortened.

(Means for Solving the Problem) This invention, which has significantly alleviated the above problems, is a support means for a shower pipe that is connected to a reciprocating drive device and repeats reciprocating motion in the axial direction of the pipe while spouting cleaning liquid. , a roller made of polyurethane or other resin that can roll while supporting the bottom surface of the shower pipe (referred to as a resin roller in this manual), and a roller made of resin that can be moved freely in the direction of movement of the supported pipe. This shower pipe support device is characterized by comprising a roller receiving box with a flat surface that can reciprocate.

(Function) It has been known since ancient times that when transporting heavy objects, rollers were inserted between the object and the sliding surface to reduce frictional resistance. In the case of this invention, even if the weight of the shower pipe increases, the energy consumption does not increase much because the resistance is small. Furthermore, even if the shape of the shower pipe that comes into contact with the roller is somewhat uneven, it will shift as it should, and there will be no structural changes to the equipment, such as wear or increased consumption.

Also, it is easy to install, just put the roller in the roller receiving box and place the shower pipe on top of it.The shower pipe and roller do not necessarily have to be inserted at right angles, and even if they are not at right angles, it is necessary to insert the roller 4 or 5 times. Just by repeating the reciprocating movement, it will be corrected to a nearly right angle. In V-groove and groove-shaped rollers, the shower pipes serve as guides and intersect at right angles, so there is no problem.
It has many of the advantages mentioned above and is a major improvement over previous mechanisms.

(Embodiment) FIG. 1 is a plan view showing an embodiment of this invention applied to a shower pipe for a paper mill, and FIGS. 2 and 3 show a cross section of the shower pipe support device. In FIGS. 4 and 5, only the support device is shown in side view and longitudinal section.

The reciprocating drive device is 1, the shower pipe is 2,
The shower pipe support device of this invention is designated as 10, the resin roller as 11, and the receiving box as 12.

Shower pipe 2 is a straight pipe, which is supported by support device 1
Even two pieces are supported so that they can move back and forth. One support device 10 is fixed to the side surface of the base of the reciprocating drive device 1, and the other is fixed to the bracket 3.

The resin roller 11 of this embodiment has a cylindrical shape with both end faces bulged, and is made of a tough resin such as polyurethane or nylon. Due to its toughness, even if it is cylindrical, when it reciprocates 4 to 5 times as described above, it will self-correct the direction of its axis so that it is perpendicular to the direction of the shower pipe 2 placed on it.

At present, it is not clear why such a favorable effect occurs, but the place where the pipe 22 is placed is slightly indented, and a direction correction effect similar to that of a string-like roller, which will be described later, appears. I wonder if it will come.

In short, the roller receiving box 12 only needs to have a flat surface that accommodates the rollers 11 and allows the rollers 11 to freely reciprocate in the moving direction (pipe axis direction) of the pipe 2 supported by the rollers 11 over a moving distance.

In the receiving box 12 of the embodiment shown in FIGS. 4 and 5, one side wall is used as a base and a mounting surface for the bracket, so only one side wall 12a is extended upward, and the opposite side wall is used as a mounting surface for the roller 1.
It is kept at a height that is sufficient to guide 1. Koro 1
The bottom plate 12b on which the pipe 1 rolls is, of course, flat, and its longitudinal length is slightly longer than the reciprocating distance of the pipe 2. Stop plates 13 are attached to the front and rear ends of both side walls to prevent the rollers 11 from escaping.

Further, the receiving box 12 of this embodiment has a cover 14 that also covers the pipe 2 on the roller 11. This cover 14 covers the open surface of the receiving box 12 to prevent cleaning liquid and foreign matter from entering the roller 11 and its rolling path. An L-shaped plate is attached to the receiving box 12 so as to wrap around the opening on the lower side wall. The cover 14 in this embodiment has the same length as the receiving box 12, but it may also be a full-fledged cover that protrudes from the front and back, or opens only the opening through which the pipe 2 passes, thereby sealing the receiving box 12.

The reason why the resin plates 15 are attached to the inner surfaces of the opposing side walls of the receiving box 12 is to control the irregular movement of the shower pipe 2 when it becomes particularly large, so that the pipe 2 is not touched at all times. The dimensions of the receiving box 12 are determined and positioned in this manner.

The position of the resin rollers 11 is such that the pipe 2 is initially placed close to either the front or rear stop plate 13, and the rollers 11 are moved to the opposite side together with the pipe 2, so that the resin rollers 11 are positioned close to the turning path, that is, the front or rear of the box bottom. It is sufficient that the length is slightly longer than the one-way reciprocating distance of the pipe 2. However, one of the advantages of this idea is that Colo 1
Even if you carelessly throw 1 into the receiving box 12, the roll 1
1 collides with the stop plate 13 only once, and then reciprocates smoothly from the correct starting point, and the rollers 11 roll correctly at right angles to the pipe 2 in 4 to 5 times. Therefore, as long as the pipe 2 repeats normal reciprocating motion, the rollers 11 in the receiving box 12 simply roll on the bottom surface, and other parts do not restrict the rollers 11.
There is no need to add any friction to this. The fact that the rollers 11 roll freely is a major difference from conventional bearing rollers which are restricted by bearings.

As mentioned above, even if the resin roller 11 of this invention is cylindrical, it has the effect of automatically correcting the direction of rotation so that it follows the reciprocating direction of the shower pipe 2, but this requires 4 to 5 reciprocations. movement is necessary.
Therefore, the two examples of rollers shown in Figs. 6 to 9 are designed to perform the same corrective action with one or two reciprocating movements. The roller 11 shown in FIGS. 6 and 7 has a V-shaped central portion that supports the pipe 2, while the center portion of the roller 11 shown in FIGS. 8 and 9 tapers into an arcuate groove shape. A pipe 2 is attached to the roller 11 having these circumferential grooves.
It is obvious that if the rollers 11 are mounted and rotated reciprocally, the direction of the rollers 11 will be along the axial direction of the pipe 2.

Next, as a rather special embodiment of this invention, a shafted roller 11' with supporting shafts 16 protruding from both sides of the roller is used.
I will explain what uses .

Two examples of shafted rollers 11' are shown in FIGS. 10-13. The shape of the rollers is the same as that shown in Figures 6-9. A simple cylindrical roller with a supporting shaft 16 is shown in FIGS. 14-16 together with a receiving box 12' for the roller. In this case, the roller 11' is a resin roller through which a support shaft 16, which is a steel rod, is passed.

The difference between the receiving box 12' for rolling the shafted roller 11' and the receiving box 12 for the shaftless roller 11 shown in FIGS. 4 and 5 is that the flat surface for rolling the rollers of the receiving box is not the bottom of the box.
This is a point that has changed to the lower surface 17a of the horizontal groove 17 on both side walls of the receiving box. The lower surface 17a, that is, the lower groove wall serves as a flat surface for roller rolling, and causes the roller support shaft 16 to roll.

The shafted roller 11' itself is the same as a conventional shaft-supported roller, but the shaft 16 of the roller 11' does not rotate within a bearing as in the conventional case, but instead rotates on the lower surface 17a of the horizontal groove of the roller receiving box 12'. Needless to say, the length of the lateral groove 17 corresponds to the moving distance of the pipe 2.

Although a small number of embodiments have been described above, this invention can be varied and applied in a variety of ways depending on the implementation conditions without changing the gist of the invention using well-known techniques of the designer.

(Effects of the invention) This invention was the first to replace the axially supported rollers, which have always been used as a support device for shower pipes that reciprocate in the axial direction, with resin rollers and their receiving boxes. The realization of this new concept eliminates the roller shaft support, which is prone to breakdowns due to cleaning fluid and foreign matter getting into it, and replaces it with a receiving box with a flat surface that allows the rollers to freely roll over the required distance, making breakdowns more likely. It decreased.

In addition, the structure is simplified, installation work is easy,
It has many benefits such as ease of maintenance and long life.
