Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric sheet peeling machine that is applied to peel off a sheet that has been laid down with adhesive on a floor surface.

Conventionally, in order to peel off the above-mentioned floor sheet, a cut was made in the floor sheet using a regular cutter, a rolled-up part was created using the cutter at one end of the sheet, and then the adhesive was softened using a burner at the rolled-up part. It took several people to pull up the sheet and peel it off, but such sheet peeling means has drawbacks such as being labor-intensive and inefficient, and causing severe wear and tear on the cutter.

Therefore, a cutter specifically for removing floor sheets is currently known, which is equipped with a horizontal blade formed on the main body and a vertical blade that faces in the same direction as the horizontal blade and is approximately perpendicular to the horizontal blade. It is attached to a compressor or electric motor and is used by sliding it on the floor while poking the floor at a certain angle.In this way, the horizontal and vertical blades cut the sheet while partially separating it from the floor. A rolled-up portion is formed in the cut portion, and the sheet is pulled up and peeled off while heating the floor surface of the rolled-up portion with a burner or the like.

However, even with such a special cutter, the sheet cannot be directly peeled off, and after cutting the sheet to make it easier to create a rolled part, the adhesive must be heated with a burner as in the conventional method described above. In addition, since the sheet is artificially pulled up and peeled off while heating, it has the same drawback as the above-mentioned conventional method, which requires time and effort. has the disadvantage that it cannot be used because there is a risk of burning the floor surface due to heating.

The present invention is an attempt to eliminate the above-mentioned drawbacks of the conventional technology.
In the electric sheet peeling machine, a scraper 4 is removably fixed to the lower surface of the tip of the base plate 3, and a cutting edge 4a provided at the tip of the scraper 4 has a An upper side surface 4b and a lower side surface 4c each formed at an acute angle with respect to the tip surface of the scraper 4 are provided,
A guard plate 5 that slopes upward to the rear is fixed to the top surface of the tip of the base plate 3, and a plurality of omnidirectional rotary moving rollers 6 are attached to the bottom rear position of the base plate. By forming a stripping section 1 and attaching a horizontal diaphragm 12 of a vibrating body 2 such as an electric sander to the base plate of the stripping section, the scraper vibrates in all directions in a horizontal state. As a result, sheets can be easily and efficiently stripped off over a predetermined width by simply moving the machine forward lightly, without the need to force the machine forward, and the cutting edge will not damage the floor surface. Therefore, the purpose is to provide an electric sheet peeling machine that can be applied to peeling sheets laid on floors made of various materials.

The present invention will be described in detail below based on an illustrated embodiment.As shown in FIG.
It is composed of.

As shown in FIG. 2, the peeling section 1 is formed of a rectangular base plate 3 having appropriate vertical and horizontal dimensions, a scraper 4, a guard plate 5, and an omnidirectional rotating roller 6. ing.

That is, the peeling section 1 is located at the tip of the base plate 3, and the scraper 4 is attached to the bottom and top surfaces of the base plate 3.
The base plate 3 is fixed with a plurality of countersunk machine screws 7 and nuts 8 while the guard plates 5 and 5 are stacked on top of each other.
A plurality of the moving rollers 6 (two in the figure) are fixed to the rear bottom surface of the roller with pan-head machine screws 9.

The horizontal widths of the scraper 4 and the guard plate 5 are formed to be equal to that of the base plate 3, and the cutting edge portion 4a machined at the tip of the scraper 4 with respect to the base plate 3 is shown in FIG. Just like that,
In order to facilitate insertion between the floor surface 10 and the seat 11, the scraper 4 is made to protrude forward by an appropriate amount from the tip 3a of the base plate 3, and the scraper 4 is made of a steel plate or the like to ensure durability. As shown in FIG.
The angles α and β between b and the lower surface 4c are each approximately 45 degrees, and the blade edge 4a is structured so that it can be easily removed by loosening the countersunk screw 7 when polishing the blade edge 4a. be.

Further, the guard plate 5 has a front portion formed into a horizontal plate portion 5a.
The rear part is formed with an inclined plate part 5b which slopes upward to the rear, and the horizontal plate part 5a is superimposed on the upper surface of the tip part 3a of the base plate 3 and is detachably fixed. The inclined plate portion 5b at the rear is provided to guide the peeled sheet so that it does not directly hit the vibrating body 2, as will be described later.

Further, the rear part of the guard plate 5 is connected to the inclined plate part 5.
Of course, instead of b, a curved plate portion curved upward may be used.

Moreover, as the moving roller 6, a mounting cylinder 6a is used.
It is best to use a roller with a sphere 6b supported for rotation in all directions at the tip of the roller.When such a moving roller 6 is used, the mounting tube 6a is fixed to the base plate 3 by screwing it. be done.

Thus, the peeling part 1 is removably fixed to the horizontal diaphragm 12 of the vibrating body 2 with screws 13, as shown in FIG. 4, by providing a plurality of mounting holes 3b in the base plate 3. The sheet peeling machine is configured.

Here, an existing orbital sander or the like can be used as the vibrating body 2, and this will be explained based on FIG. 4.

A balance weight 16 is fixed to the drive shaft 15 of the motor built in the motor frame 14, and a drive plate 17 is attached to the drive eccentric pin 15a eccentrically extended at the tip of the drive shaft 15 via a bearing. The drive board 17 and the motor frame 14 are connected by a sheet rubber 20, and the horizontal diaphragm 12 is fixed to the bottom of the drive board 17 with screws 18. 12 is configured by being connected to a motor frame 14 via a cushion support 19.

In the figure, 21 indicates a handle, and 22 indicates an auxiliary handle.

As the drive shaft 15 is rotated by energizing the motor, the drive board 17 supported by the eccentric pin 15a is rotated horizontally in all directions by the amount of eccentricity of the eccentric pin 15a. As a result, the horizontal diaphragm 12 is swung to the base plate 3.
It is vibrated horizontally in all directions with . In this way, the vibrations of the base plate 3 are directly transmitted to the scraper 4, and the vibrations are transmitted to the tip end portion 4a in all directions. A notch is formed in a part, and when the cutting edge 4a of the scraper 4 is inserted into the cut and moved forward slightly, the vibration of the cutting edge 4a is generated between the floor surface 10 and the sheet 11, and the sheet 11 is bonded. This causes the sheet 11 to be peeled off.

Therefore, by moving the machine forward, the sheet 11 can be stripped off along the width of the scraper 4 as shown in FIG. Since the sheet 11a is wound in front of the guard plate 5 as shown in the figure, it does not interfere with the peeling operation.

Also, the aircraft is moved forward with the movable roller 6 of the base plate 3 in contact with the floor surface 10.
Since the rollers 6 rotate in all directions, the machine can move freely in a desired direction, and during this forward movement, the blade tip 4 of the scraper 4
Since a is machined to the desired angles α and β so that it does not dig into the floor surface 10, it can be pushed forward lightly at a constant angle with the floor surface 10.

Incidentally, the peeling section 1 is formed to have a size that allows the vibrating body 2 to be accommodated in the upper part.

As explained above, the electric sheet peeling machine according to the present invention is constructed and operated, and therefore, the horizontal diaphragm 12 of the vibrating body 2 of an existing electric sander or the like is fixed on the base plate 3. When the base plate 3 and the scraper 4 fixed to the tip thereof are vibrated in all directions in a horizontal state, the vibration is transmitted to the blade edge 4a of the scraper 4, so that the blade edge 4a is moved to the floor surface 10. By simply inserting the sheet 11 between this and the adhesively laid sheet 11 and pushing the machine lightly, the vibration of the blade edge portion 4a acts on the adhesive portion, allowing the sheet 11 to be easily moved along the width of the scraper 4. In addition, since the blade edge portion 4a and the movable roller 6 rotating in all directions are in contact with the floor surface 10, there is extremely little frictional resistance when pushing the machine forward, so it can be freely moved in the desired direction. It can be pushed forward easily and has excellent operability, and the vibrations at the cutting edge 4
Although the information is directly transmitted to Even if the scraper 4 does not damage the floor surface 10 by the cutting edge portion 4a, it can be applied to peeling off sheets adhered to floors made of concrete, wood, plywood, and various other materials.Furthermore, the scraper 4 is Its cutting edge 4
When the vibrator a becomes worn out, it can be easily replaced, and since the existing vibrating body 2 can be used, it is inexpensive, and has many excellent practical effects.
