Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for peeling off a covering material bonded to a floor, wall, etc.

For example, the floors and walls of buildings and houses are bonded to covering materials such as tiles or interior materials made of plastic, rubber, or other materials, and when the covering materials become damaged or obsolete, they are replaced with new ones. It will be done. This replacement work involves cutting and peeling off the adhesive that joins the covering material, but because the bond is so strong, it is extremely difficult to do it manually, so a mechanical peeling device was devised. has been done.

As disclosed in, for example, Japanese Utility Model Application Publication No. 53-162527, the conventional device has a cutter mounting member pivoted on a horizontal axis at the front of the device stand, and a cutter is attached to the lower end of this mounting member. The member is configured to be swingable in the front-rear direction, and the cutter is moved in the same direction as the advancing direction of the device stand to cut the adhesive and peel off the covering material.

With this conventional device, the cutting direction of the cutter is the advancing direction, making it difficult to cut and requiring a large manual push force to support the reaction force.Also, since the mounting member swings around the horizontal axis, the height of the cutter remains constant. This makes it difficult to apply the tip of the cutter to the adhesive, resulting in very poor workability.

In view of the problems of such conventional devices, the present invention has been made to
To provide a peeling method and device capable of cutting an adhesive material smoothly and beautifully by reciprocating a cutter in a direction intersecting the advancing direction of a device stand, and which can be performed with light work.

The method of the present invention for achieving this purpose is characterized by peeling off the covering material while cutting the adhesive material joining the covering material with a cutter, while moving the cutter forward in a direction crossing the cutter. The device of the present invention is characterized in that the device of the present invention peels off the coating material while cutting the adhesive bonding the coating material with a cutter. A pair of left and right actuating arms supported by a pair of left and right actuating arms, a cutter attached to the tip of each actuating arm and whose blade portion can be brought close to the coating joint surface in front of the equipment table, and a pair of left and right cutters that intersect with the direction of movement of the equipment table. In order to reciprocate the left and right operating arms in opposing directions, the apparatus includes a drive mechanism that swings or linearly moves the ends of the left and right operating arms simultaneously in opposite directions.

A rolling element 19 made of a bearing is installed at the front lower part of the device stand 2 with a bolt 18, and a backing plate 20 provided in front of the guide bodies 14 and 15 of the operating arm 13 contacts the rolling element 19. The attitude of the actuating arm 13 is regulated so that it is in contact with the actuator arm 13 and is substantially horizontal.

The front end of the actuating arm 13 protrudes forward from the device stand 2, and an arcuate plate is orthogonally welded to form a cutter mounting surface 21. The cutter mounting surface 21 has a medium-high arcuate shape, with the center portion in the left-right direction being higher than both sides.

22 is a cutter, and the left and right operating arms 13A, 13
A number of square blades 23 are formed on the blade portion 22a at the tip of each blade, and these square blades 23 are attached not only to the front edge but also to the left and right side edges. It also serves as a cutting blade. This cutter 22 is fixed to the cutter mounting surface 21 via a bolt 24, but since the mounting surface 21 is medium-high, the approximately rear half of the cutter 22 is also elastically deformed into a medium-high arc shape, and the cutter 22 Even if the blade part 22a is pressed against the floor surface C, the blade part 22a is prevented from being deformed such that it warps upward, and is mounted so that substantially the entire length thereof always contacts the floor surface C uniformly.

A peeling guide plate 26 is bolted to the front surface of the apparatus stand 2. This peeling guide plate 26 has left and right tongue pieces 26a and a center tongue piece 26b.
extends between the two cutters 22A and 22B, and peels off the covering material E upward where the adhesive D has been cut by the cutters 22.
