Description

  The present invention relates to a polishing apparatus for scissors and chisels.

  Conventionally, manual operations by skilled workers have been the main focus for polishing blade edges such as scissors and chisels. At that time, the blade tip was pressed against the rotating polishing machine, and the work was performed while applying a certain angle and pressure. Therefore, when an unfamiliar worker performs this work, the finish of the cutting edge becomes unstable and there is a risk of injury. Therefore, various polishing apparatuses have been proposed that can easily polish the cutting edge of a blade by any unskilled worker.

  For example, a polishing mechanism composed of a rotating mechanism for rotating a wet cylindrical grindstone and a water tank containing water for moistening the grindstone, a reciprocating drive unit for attaching a cutter, and a tool for pressing the cutter against the grindstone Has been proposed (see Patent Document 1). The blade polishing apparatus is provided with a vertical movable portion and a pressure adjusting mechanism that adjusts the force for pressing the blade against the grindstone.

  Also, a gantry with casters, a blade support plate whose base end side is fixed to the gantry so as to be movable up and down, an inclined plate formed on the distal end side, and a rear surface of the inclined plate, which can be moved up and down. There has also been a blade polishing apparatus comprising a blade mounting base configured with the formed blade clamping plate and a block-shaped grindstone (see Patent Document 2).

  However, the blade polishing apparatus of the above-mentioned patent document 1 rotates a cylindrical grindstone in the circumferential direction and abuts the side surface with the blade to perform polishing, and moves at a constant speed in the blade crossing direction of the blade. Therefore, it is necessary to perform polishing, and a complicated mechanism for following a subtle change in the contact state with the grindstone is required, resulting in an extremely complicated structure.

  In addition, the technique described in Patent Document 2 is capable of polishing by moving a caster while holding a ridge etc. at a fixed angle and set to be horizontal with the grindstone surface. It was impossible to cope with changes in parallelism due to surface abrasion.

  Therefore, the present invention has been made in view of the above-described conventional problems, and the cutting edge of a blade having a straight blade such as a scissors has a simple structure and can be polished safely and reliably for any unskilled operator. A polishing apparatus is provided.

  For this reason, the polishing apparatus of the present invention is a polishing apparatus comprising a polishing disk for polishing the cutting edge of a blade, a driving device for rotating the polishing disk, and a contact mechanism for contacting the cutting edge of the blade to the polishing disk. The grinder is a grindstone that has a gently curved surface from the center to the outer periphery, and the abutment mechanism is erected on a pedestal on which the grinder is placed, and a vertically movable pole and a tip of the pole. It is provided with a blade guide that is provided, holds a blade that needs to be polished at an arbitrary angle, and is rotatable around the pole, and a movable handle that is integrally attached to the blade guide.

  A blade is attached to the blade guide, and the blade tip of the blade is brought into contact with the surface of the polishing board by a movable handle, and is polished while rotating left and right around the pole axis. A straight blade can be formed.

  According to the polishing apparatus of the present invention, a pole that is movable up and down, and a blade guide that is provided at the tip of the pole, holds a blade that needs to be polished at an arbitrary angle, and is rotatable around the pole. And a cutter abutment mechanism composed of a movable handle integrally attached to the cutter guide. A cutter requiring polishing is attached to the cutter guide, and the movable handle is operated to contact the polishing disc. Thus, any unskilled worker can safely perform the polishing work.

  In addition, by rotating and driving a grindstone that has a gently curved surface from the center to the outer circumference, the blade edge of the blade is brought into contact with the movable handle while rotating it to the left and right. It has the outstanding effect that can be formed.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings, but it goes without saying that the present invention is not limited to this embodiment. FIG. 1 is a perspective view of the polishing apparatus of the present invention, FIG. 2 is a side view of the polishing apparatus of the present invention, and FIG. 3 is a plan view of FIG.

  As shown in FIG. 1, a polishing apparatus 1 according to the present invention includes a rotary polishing machine 2, a pedestal 3 on which the rotary polishing machine 2 is placed, and a blade holder 4 erected on the pedestal 3. The cutter 5 having a straight blade such as a scissors is held by the cutter holder 4 and pressed against the surface of the grindstone 6 of the rotary polishing machine 2, and the cutter 5 is rotated left and right around the axis of the cutter holder 4. While polishing.

  2 is an explanatory side view of FIG. 1, and FIG. 3 is an explanatory plan view of FIG. As shown in the figure, the rotary polishing machine 2 is placed on a pedestal 3 so that the grindstone 6 can be rotated forward and backward by rotation of a motor (not shown). 4 is erected.
