Abstract

PURPOSE:To provide a polishing device which can certainly and effectively polish a work evenly to its every corner. CONSTITUTION:On a frame 1 a polishing chamber 2 is horizontally installed swingably, and on the chamber inner surface in the switching direction, a number of projections 5 are densely provided in dislocations alternately. When the polishing work is performed, the projections serve as so-called baffle plates so that the polish A is fluidified in random turbulences, and a work B can be polished evenly to its every corner certainly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing apparatus mainly used for polishing relatively small-sized objects such as eating and drinking tools and cooking tools.

[0002]

2. Description of the Related Art Conventionally, as a polishing apparatus of this type,
A polishing tank having a semicircular cross-section container shape is horizontally arranged on a required mount via a pair of rollers on both sides, and a crank mechanism is attached to one outer peripheral wall of the polishing tank via an arm. It is known that the polishing tank is pivotally attached and the polishing tank is caused to swing along the circumferential direction by the operation of the crank mechanism (see Japanese Patent Laid-Open No. 4-75864). In such a conventional polishing apparatus, a required object to be polished such as food and drink is put into the polishing tank together with the polishing material, and then the polishing tank is swung left and right along the circumferential direction through a crank mechanism. Then, due to the swinging of the polishing tank, the polishing material flows in a vertical plane in a substantially lateral 8-shaped trajectory to perform predetermined polishing.

[0003]

By the way, in the conventional example configured as described above, since the polishing material is fluidized in the vertical plane in a substantially lateral 8-shaped trajectory by the swinging of the polishing tank, The flow path of the abrasive material is always constant and regular, so that the object to be polished cannot be uniformly polished in every corner, and a satisfactory polishing effect cannot always be expected. .

The present invention intends to solve the problems of the prior art all at once, and to provide a polishing apparatus capable of uniformly and reliably polishing an object to be polished in every corner.

[0005]

That is, according to the present invention, a required polishing tank 2 is horizontally arranged on a pedestal 1 so as to be swingable, and the polishing tank 2 has an inner peripheral surface along the swinging direction. Is a structure in which a large number of protrusions 5 are alternately and densely formed.

[0006]

[Operation] A polishing tank 2 which is horizontally swingably mounted on a pedestal 1.
Since a large number of protrusions 5 are alternately and densely formed on the inner peripheral surface along the swinging direction of the, the protrusions 5 act as a so-called baffle plate to cause the abrasive A to flow in an irregular turbulent flow. As a result, every corner of the object B to be polished can be uniformly and surely polished.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 is a pedestal in the shape of a rectangular body, 2 is a rectangular vessel-shaped polishing tank horizontally disposed on the pedestal 1 via a pair of rocking shafts 3 on both sides, and each rocking shaft 3 is The lower ends of both sides of the polishing tank 2 are attached to the crocodile, and are configured to set the swinging center of gravity of the polishing tank 2 low. Reference numeral 4 denotes a double-opening lid body that is openably and closably attached to the upper surface of the polishing tank 2, and 5 denotes a large number of hemispherical protrusions that are alternately and densely formed on the inner peripheral surface of the polishing tank 2 along the swinging direction. Reference numeral 6 denotes a crank mechanism connected to one swing shaft 3 via a disk body 7 so as to swing the polishing tank 2 at a predetermined angle in the circumferential direction. The crank 8 constituting the crank mechanism 6 is decelerated. The crank rod 10 is attached to the output shaft of the motor 9 with a machine, and the crank rod 10 is pivotally attached to the outer peripheral edge of the lower end of the disc body 7. In addition, A indicates an abrasive material containing large and small abrasive grains, and B indicates an object to be abraded such as a fork and a spun.

Next, the operation of the embodiment configured as described above will be described. First, the material B to be polished is put into the polishing tank 2 together with the polishing material A, and the lid 4 is closed. After that, the motor 9 is activated and the polishing mechanism 2 is swung in the direction indicated by the arrow in FIG. 3 through the swing shaft 3 by the operation of the crank mechanism 6. Then, the material B to be polished is polished while causing the polishing material A to flow in the swinging direction in association with the swinging of the polishing tank 2. At this time, since a large number of protrusions 5 are densely formed on the inner peripheral surface of the polishing tank 2 along the swinging direction, each protrusion 5 acts as a so-called baffle plate and causes the abrasive material A to have an irregular turbulent flow. The material B can be fluidized in a uniform shape to uniformly and surely polish every corner of the object B to be polished. Further, since the swing shafts 3 on both sides are attached to the lower ends of both sides of the polishing tank 2 to lower the swing center of gravity of the polishing tank 2, the polishing material A flows entirely without staying at the bottom of the polishing tank 2. Can effectively perform the polishing action. When the polishing of the object to be polished B is completed, the motor 9 is stopped, the swing of the polishing tank 2 is stopped, the lid 4 is opened to take out the object to be polished B, and the polishing operation is completed. Hereinafter, it is preferable to similarly polish the required objects B to be polished in the same manner.

Although the above embodiment shows dry polishing,
Of course, the present invention is not limited to this, and can be applied to so-called wet polishing in which water is introduced together with the abrasive A, as a matter of course. Further, in the above embodiment,
Although the polishing tank 2 is in the shape of a rectangular container, it is not limited to this and may be formed in various container shapes. Similarly, the shape of the hemispherical protrusions 5 may be changed. Needless to say, it may have any shape as long as it allows the flow of the abrasive material A to act as a baffle plate.

[0010]

According to the present invention, according to the above, the gantry 1
Since a large number of protrusions 5 are alternately and densely formed on the inner peripheral surface of the polishing tank 2 which is horizontally swingably arranged above along the swinging direction, each protrusion 5 acts as a so-called baffle plate. The abrasive material A can be fluidized in an irregular turbulent flow, and the object to be polished can be compared with the conventional example in which the abrasive material A is always fluidized with a constant regular trajectory. It is possible to polish B evenly in every corner and surely.
