Description

  The present invention is a deposit removing device that can be suitably used to remove advertisements or posters attached to the wall of a building, or to remove labels or invoices attached to the top or side of a transport box, and The present invention relates to a method for removing deposits.

  As a scraping device for scraping off deposits such as chewing gum attached to the floor surface, while reciprocating the blade having a blade portion at the tip portion in the front-rear direction, the blade tip is inserted between the deposit and the floor surface, There has been proposed one configured to be able to remove the deposit (see, for example, Patent Document 1).

  On the other hand, in the case of leasing tools used in civil engineering and construction work, a leasing tool is put in a metal transport box at a leasing store, and a invoice is attached to the side or top surface of the transport box, and the tool is sent to the customer. However, because of the repeated use of the transport box, the invoice previously attached is peeled off and a new invoice is attached each time.

Japanese Utility Model Publication No. 4-52847

  By the way, peeling of the invoice attached to the transport box is done manually using a spatula or the like, but when the transport box is made of an iron-based metal material, the attached invoice is not easily peeled off. In addition to consuming a lot of work time, there is a problem that a part of the invoice remains attached to the transport box and the transport box becomes dirty. Therefore, in order to electrify the invoice removal work, the present inventor manufactured a removal device for moving the blade in the front-rear direction, as in the invention described in Patent Document 1, and stuck it to the transport box using this device. A test was conducted to mechanically peel the invoice. However, the removal work of paper deposits such as invoices, unlike the removal work of chewing gum, can not be removed efficiently just by moving the blade in the front-rear direction. Only work efficiency equivalent to manual removal using a spatula was obtained.

  An object of the present invention is to provide a deposit removing device and a deposit removing method capable of efficiently removing deposits affixed to a transport box or a wall, such as advertisements, posters, address labels, and invoices. is there.

  As a result of further diligent study on an efficient method of removing the invoice, the present inventor has focused on the fact that a normal knife such as a kitchen knife can easily and sharply cut an object by drawing instead of pushing. The present invention has been completed with the idea that by giving the blade edge movement a component in the left-right direction, the blade edge can be pulled between the attachment and the attachment surface, and the invoice can be removed much more efficiently. It was.

The deposit removal device according to the present invention is a portable deposit removal device that peels and removes deposits from the deposit surface, and has a cutting edge that can be inserted between the deposit and the deposit surface, in so that the cutting edge of the blade is to elliptical motion, and a driving means for driving the blade, as the driving means, the vertical direction of the guide shaft portion, an elongated guide hole in the longitudinal direction of the guide shaft is inserted An output plate that has an intermediate portion, holds the cutter at the front end, and is supported to be movable in the front-rear direction with respect to the guide shaft portion and swingable about the guide shaft portion; and A device including an eccentric shaft that eccentrically rotates the rear portion and a drive unit that rotationally drives the eccentric shaft is used .

  In this removal device, the blade tip is inserted between the deposit and the adhesion surface while the blade is driven by the driving means so that at least the component in the left-right direction is included in the movement direction of the blade edge, and the adhesion portion is peeled off from the adhesion surface. Will be removed. In other words, the pulling operation of the blade when the blade edge is moved in the left-right direction can tear the boundary portion between the deposit and the attachment surface and remove the deposit, so the blade can be simply moved forward and backward. As compared with the case where the deposit is peeled off by pushing, the deposit can be efficiently peeled and removed.

Specifically, the cutting edge such that the elliptical motion, will be driven by the drive means the cutting tool. In other words, the movement of the blade edge only needs to include at least a component in the left-right direction, but a circular motion or an elliptical motion is smoother than a linear motion with only a motion component in the left-right direction. It is preferable because the cutting edge can be moved to the position. Further, such a motion can be obtained by easily converting the rotational motion of the motor into a circular motion or an elliptic motion of the blade by using a cam mechanism or the like.
Here, it is a preferred embodiment that the major axis of the elliptical motion is arranged in the left-right direction.

  It is also preferable to use a flat blade that can be elastically deformed as the blade, and to provide a pressing plate that is pressed against the upper surface of the base of the blade, and to deform the blade into a curved shape that is lowered toward the blade edge by the pressing plate. It is. With this configuration, even if the cutting edge side of the blade is pressed against the attachment surface, the blade will not be warped, so the blade edge is inserted between the attachment and the attachment surface while pressing the blade edge side of the blade against the attachment surface. Therefore, the deposits can be removed effectively and cleanly.

  It is also possible to provide a cover member with an open bottom surface that can be packaged on the blade. By providing such a cover member, it is possible to prevent scattering of chips and dusts generated when removing the deposits. Further, by covering the blade with the cover member, it is possible to prevent damage to the blade during transportation or damage to other objects due to the blade.

  It is also a preferred embodiment that the drive part of the drive means is constituted by a drive part of an electric tool. If the drive unit is configured by a drive unit of a general-purpose electric tool, the manufacturing cost of the removal device can be significantly reduced.

The method for removing deposits according to the present invention includes a guide shaft portion in the vertical direction and a long and narrow guide hole in the front-rear direction through which the guide shaft portion is inserted as a driving means for the blade. An output plate that is movable in the front-rear direction with respect to the guide shaft portion and is swingably supported around the guide shaft portion, an eccentric shaft that eccentrically rotates the rear portion of the output plate, and the eccentricity Using a tool equipped with a drive unit that rotates the shaft , the blade tip of the blade is inserted between the attached surface and the attached material while driving the blade so that the blade tip moves elliptically , and the attached material adhered to the attached surface. Is removed.

In this removal process, the so that to the cutting edge is elliptical movement, while driving the blade by a driving means, against the cutting edge between attachment surface and deposit will be separated remove adhering portion. That is, the tool pulling operation when the cutting edge is moved in the lateral direction, tearing through the boundary between the deposit and the deposition surface, it is possible to remove deposits, it was simply to move the blade towards the front and rear, Compared with the case where the deposit is peeled off by pushing, the deposit can be efficiently peeled and removed.

According to the deposit removal apparatus and the removal method of the present invention, the blade edge is moved between the deposit and the adhesion surface while the blade is moved elliptically by the driving means so that the movement direction of the blade edge includes at least a component in the left-right direction. Is inserted and the adhering portion is peeled off from the adhering surface.
