Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a wiper that is attached to an end face of a moving member that slides on a guide surface of an industrial machine and its auxiliary equipment.

Wipers are usually attached to the end faces of machines and attached devices to prevent foreign matter from entering the sliding area between the guide surface and the moving member.

Therefore, the wiper is attached so that its lip portion is always in pressure contact with the guide surface, and the wiper is prone to wear and may need to be replaced.

When replacing the wiper, it may be possible to simply remove and mount the wiper, but depending on the cross-sectional shape of the guide surface, it may be necessary to remove the moving parts and other parts from the guide surface, disassemble the wiper, or replace the wiper. It was necessary to cut it into easy shapes and install it.

However, replacing the wiper by disassembling the movable members and other parts has the disadvantage that it takes a lot of man-hours and a lot of work time.

Furthermore, when a split type wiper is used, there is a drawback in that it is not possible to completely prevent foreign matter from entering through the rear seam during assembly.

The object of the present invention is to provide a wiper that eliminates the above-mentioned drawbacks for a guide surface having a cross-sectional shape that makes it impossible to easily replace the wiper alone.

Next, embodiments of the present invention will be explained with reference to the drawings.

1 is a bed guide surface having a cross-sectional shape that makes it impossible to easily replace the wiper; 2 is a flat wiper attached to the end surface of the movable member 3 and shaped along the guide surface; a rubber body 4;
A mandrel is embedded in the rubber body 4 and has a similar shape to the rubber body, and the rubber body 4 and the mandrel 5 are integrally molded in an adhesive state.

The mandrel 5 is cut off at part A in FIGS. 1 and 3, and is connected to the wiper 2 only through the rubber part.

When replacing the wiper with the movable member 3, the wiper is bent at this portion A and fitted into the guide surface 1, and after fitting, it is returned to its original shape and tightened to the end face of the movable member 3.

Note that the state of part A is not limited to the above shape, as long as it is connected to the lip part 6 of the wiper 2 and can be bent.

It is also possible to connect only the lip part and cut out the rubber body of part A, or to separate the mandrel so that it does not come off.

By configuring the wiper as described above, it becomes possible to easily replace the wiper, improving work efficiency and completely preventing foreign matter from entering between the guide surface and the moving member.

Claims (1)

[Scope of utility model registration request] In a wiper that is fixed to a movable member that slides on a guide surface of an industrial machine and its auxiliary equipment, the wiper has a flat elastic member that is shaped along the guide surface and a flat elastic member that is also flat and almost similar to the elastic member. A wiper comprising a shaped mandrel embedded in an elastic member, the mandrel being separated at at least one point so that only the elastic member can maintain connection and be deflected.
