BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material peeling machine for peeling a floor material adhered to a floor surface of a building. More specifically, the floor material is cut by using a slicing action of a cutter. The present invention relates to improvement of a cutter for a floor material peeling machine that peels from a surface.

[0002]

2. Description of the Related Art P tiles, C stretched on the floor of a building
When relining floor materials such as F, needle punch, ronreume, rubber back, carpet, etc., the floor material peeling machine shown in FIGS. 6 to 8 is generally used in order to save labor in the floor material peeling work. This floor material peeling machine 10 has a rear wheel 1
A pair of operating arms 14 drivingly connected to a drive motor 13 is swingably provided on the lower part of the carriage 12 supported by 1. The lower weight 15 and the upper weight 1 for adjusting the contact force of the cutter 1 with the floor surface.
6 and 6 are selectively installed above the front part of the carriage 12. In each cutter 1, the cutter body 2 is made of a thin steel plate, and as shown in FIG. 8, a plurality of blade portions 3 are formed at the tip portion of the cutter body 2 at substantially the width intervals of the blade portion 3, and an operating arm is provided at the rear end portion. A plurality of mounting grooves 6 to be mounted on 14 are formed. When using, for example, when peeling P tile,
The tip of the blade 3 of the cutter is brought into contact with the floor surface of concrete or the like, and the drive motor 13 is operated to reciprocate the cutter 1 to the left and right to smooth the cutter for about 30 seconds. Then, a part of the P tile is peeled off, the blade part 3 of the cutter is applied to this part, the driving motor 13 is started, and the handle 17 is pushed to move the floor material peeling machine 10 forward. Each cutter 1 reciprocates left and right by the operation of the drive motor 13, slices and cuts the adhesive portion of the floor material with the floor surface, and peels the floor material. Then, by moving the floor material peeling machine 10 forward, the cutter 1 is moved forward while being in pressure contact with the floor surface, and the adhesive portion of the floor material is sequentially cut. The cut portion moves rearward along the upper surface of the cutter 1 and the floor member guide member 18, is broken by this, and is removed by the operator. As described above, the P tiles are sequentially peeled off.

[0003]

According to the floor material peeling machine 10 described above, since it takes a lot of time to re-grind the cutter 1, there is a problem that the efficiency of the peeling work is low. That is, since the cutter 1 is reciprocally driven to the left and right while being pressed against the floor surface, the blade portion 3 is abraded and rubbed by rubbing against the floor surface. However,
Since the blade portion 3 of the cutter is thick, the tip of the blade portion 3 warps upward and separates from the floor surface as the time of use elapses, making it difficult to bite into the adhesive portion of the floor material and making the peeling work difficult. . When this state is reached, the upper weight 16 is removed to reduce the pressing force on the cutter 1 and bring it into contact with a smooth concrete surface to re-grind, but this cannot sufficiently remove the warp. Is often. Therefore, it is necessary to sharpen again with a file. The re-sharpening of the cutter 1 usually needs to be performed every 30 minutes, and one re-sharpening requires about the same time as the peeling work time. As a result, it is difficult to efficiently remove the floor material.

Further, there is a problem that a floor material peeling machine cannot be used in a facility such as a hospital because a large noise is generated during the peeling work. That is, cutter 1
Is reciprocated left and right while being pressed against the floor surface, and the blade portion 3 is discontinuously formed, so that the noise generated when the blade portion 3 rubs against the floor surface is extremely large, and The person who talks about it has a very unpleasant noise to the people around him. As a result, they cannot be used in facilities such as hospitals where quietness is required, and they must be manually operated.

The present invention has been made in order to solve the above-mentioned problems of the prior art. The object of the present invention is to provide a cutter for a floor stripping machine which does not require re-grinding during use and which can reduce noise. To provide.

[0006]

In order to solve the above-mentioned problems, the present invention provides a cutter tilted forward, and a cutter blade portion is pressed against the floor surface to move forward and backward while reciprocating left and right, A cutter of a floor material peeling machine that cuts and peels off the adhesive portion of the floor material to the floor surface, in which the cutter body is formed by a thin steel plate whose front and back surfaces are parallel to each other, and the tip of the cutter body By alternately forming the recessed groove over a predetermined width and length at a predetermined interval on the back surface side and the front surface side, the corresponding front surface side and back surface side are thin-walled portions of uniform thickness, and both ends The edge and the space between the adjacent thin portions are used as the reinforcing ribs, and the blade portions having the thin portions on the surface sides near both ends are formed.

The blade portion may have a thin portion on the front surface side near both ends and a back surface side between them, and each thin portion and the front surface side of the tip of the reinforcing rib portion may be formed at an acute angle. The thickness of the thin part of the blade is 1/10 or more of the cutter body
The width of the reinforcing rib portion may be equal to or more than the thickness of the cutter body.

[0008]

[Function] Since the blade portion of the cutter has a reinforcing rib portion having the same thickness as the cutter body between the both end edges and the thin portion,
It has sufficient rigidity to withstand the pressing force acting on the blade of the cutter, and the thin-walled part contacts the floor surface uniformly without deformation. Then, during the peeling work, it is sequentially ground by rubbing against the floor surface, but since the front surface side and the back surface side are alternately thin parts, the tip does not warp upward, Properly abut the bonded part of the material. This state is maintained until the cutter wears out in an unusable state, and the peeling work can be continuously performed without the need to re-grind the blade portion during the peeling work.

Further, in the blade of the cutter, the tips of the thin-walled portions and the reinforcing ribs are in contact with the floor surface, and are continuously in contact with the floor surface over the entire width direction. that time,
Since the tip of the thin portion on the front side protrudes forward from the tip of the thin portion on the back surface, the tip of the thin portion on the front side first comes into contact with the adhesive portion of the floor material and is cut and left. The portion will be cut at the thin portion on the back side. That is, the adhesive part of the floor material on the same line is cut in stages. As a result, the cutting resistance as a whole becomes smaller than before,
The pressing force for bringing the blade portion into contact with the floor surface can be made smaller than in the past.

[0010]

Embodiments of the present invention will be described with reference to the drawings. Figure 1,
2 and 3 are front views conceptually explaining the first embodiment. In the cutter 1 shown in the figure, the cutter body 2 is formed of a thin steel plate having front and back surfaces parallel to each other, and a blade portion 3 is formed at the tip of the cutter body 2. The blade portion 3 is formed by cutting over a predetermined width and length on the back surface side near both ends of the tip end portion of the cutter body 2 and the front surface side between them to form a concave groove, and thereby the corresponding front surface side and back surface side. The side is formed into a thin portion 4 having a uniform thickness. Further, a space between the thin-walled portions 4 adjacent to both end edges is left wider than the thickness of the cutter body 2, and is formed as a reinforcing rib portion 5. At the rear end of the cutter body 2, a mounting groove 6 to be mounted on the floor material peeling machine shown in FIGS. 6 and 7 is formed.

Using the cutter 1 shown in the first embodiment, P
When the tile is peeled off, the mounting groove 6 side is fixed to the operation arm 14 with bolts or the like as shown in FIGS. After that, the cutter 1 is smoothed in the same manner as in the conventional case. In the cutter 1, as shown in FIG. 3, the tip of the blade portion 3 is formed at a substantially right angle, and the back surface tips of the thin portion 4 on the back surface side and each reinforcing rib portion 5 are in contact with the floor surface. Each back surface is polished and sharpened including the tip of the thin portion 4 on the front surface side. Then, after a part of the P tile is peeled off from the floor surface by hand, the blade part 3 of the cutter is brought into contact with this part to start the operation. The cutter 1 is reciprocally driven left and right by a drive motor to cut the adhesive portion of the P tile,
By pressing and advancing the floor material peeling machine 10, the bonded portion of the P tile is sequentially cut and peeled. For example, the cutter body 2 is a thin steel plate with a thickness of 2 mm, and the thin portion 4 is 0.4 mm.
When the peeling work was performed using the cutter 1 which was formed to be thick, the reinforcing rib portions 5 at both edges were formed to have a width of 4 mm, and the reinforcing rib portions 5 between the thin portions 4 were formed to have a width of 2 mm, the blade portion was Three
It could be used until it reached an uncuttable state due to wear without re-sharpening. The sound generated by the blade portion 3 of the cutter and the floor surface rubbing against each other was not offensive to the operator and others, and the peeling work could be performed relatively quietly. The life of the cutter 1 was long, and it was possible to peel off an area three to four times as large as the conventional one.

Next, the cutter 1 of the second embodiment shown in FIGS. 4 and 5 is one in which the tip of the cutter blade 3 is sharply sharpened beforehand so that the break-in operation can be omitted. Except for this, the configuration is similar to that of the first embodiment. Therefore, the second
When the cutter 1 of the embodiment is used, the peeling work can be started without performing the leveling operation. In addition,
As the cutter in each example, ordinary steel is sufficient,
Special steel may be used.

[0013]

EFFECTS OF THE INVENTION According to the present invention, since the blade portion is formed thin, the tip does not warp upward unlike the conventional case, and the tip is always polished by the self-polishing action by rubbing against the floor surface. Sharpened sharply. Therefore, it is not necessary to re-grind the cutter during the peeling work, and the cutter can be continuously used until it becomes worn out. As a result, the peeling work can be efficiently performed in a much shorter time than in the past.

Cutting the adhesive portion of the floor material first with the thin portion on the front surface side of the blade portion, and then cutting the remaining portion with the thin portion on the back surface side to cut the adhesive portion of the floor material stepwise. Therefore, the cutting resistance was reduced. Further, the cutting resistance was further reduced because the surface portions near the both ends of the blade portion were thin-walled portions. Therefore, the pressing force applied to the cutter can be set smaller than before, which reduces the contact resistance with the floor surface of the cutter and suppresses the wear of the cutter and prolongs its life. It was

Since the blade portion continuously contacts the floor surface over the entire width direction and the pressing force can be reduced to reduce the contact resistance with the floor surface, the cutter and the floor surface are rubbed. The noise generated by matching is much lower than before. As a result, it became possible to perform peeling work smoothly even in hospitals and other facilities that dislike noise.
