JPH09131709A - Automatic rotating machine for potter's hand wheel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To allow a hand wheel itself to be automatically rotated normally and reversely, and also its speed to be arbitrary settable by rotating the roller rotating plate by a motor, and rotating the pressure-contacted rotating plate of the patter's hand wheel. SOLUTION: A potter's hand wheel is mounted on a base plate 3. On the other hand, the motor is fixed to a frame comprising members 5, 4, 16. A roller rotating plate 10 is secured to the motor shaft and a packing 11 is provided thereto. The integrated one of the frame, motor, and roller and mounted on a base 3 by a sliding rod 16 inserted into a guide 17, and then they are tightly cramped by a hand bolt 13. In this case, a guide plate 18 and subguide plate 19 are set to restrain the hand lathe from moving. The roller is fastened to the motor shaft by a pin 15. The speed is selected arbitrarily by a dial 6. The handle bolt is screwed into a nut post 12 to be in contact with member 4. The nut post is connected to the base plate 4.

Description

Detailed Description of the Invention

[0001]

The present invention is used in pottery,
The hand-cranked wheel is automatically rotated.

[0002]

2. Description of the Related Art In the prior art, a hand-cranked wheel is made by hand. There is also a self-rotating rokuro, but the hand rokuro, which can be easily used on the table, is designed not to rotate automatically.

The conventional hand wheel is convenient and can be used on a table, but it is a pain to rotate it by hand.

[0004]

[Problems to be Solved by the Invention] The conventional hand-cranked wheel is automatically rotated forward and backward. The rotation speed can be set arbitrarily and can be easily used on the table.

[0005]

According to the present invention, a hand wheel is rotated by a motor 7. The rotary roller plate 10 is attached to the motor shaft 14, and the packing 11 is provided on the roller so as to be brought into pressure contact with the circumference of the hand wheel rotary plate 1 so as to rotate at the same time.

The motor pedestals 5, 4, 16 are made to be movable back and forth, and this is guided by a guide rod 17. Then, 13 handle bolts are provided on 12 nut rods for pressure tight contact.

A guide plate 18 and a sub guide plate 19 are provided in order to prevent the hand wheel body from being moved by a pressing force.

A speed control motor is used to arbitrarily set the rotation speed, and the dial 6 is used to arbitrarily select the rotation speed. A forward / reverse switch is provided on the wiring cord 8 so that the rotation direction can be arbitrarily selected.

[0009]

[Operation] Put a hand wheel on the base. At this time, it is inserted into the guide plate 18 obliquely, and then it is brought into contact with the inner wall surface of the sub guide plate 19 and placed on the sub-plate 3. On the other hand, the slide bar of the motor mount is inserted into the guide of 17. Roughly swaging motor and roller rotating plate 10 Packing 11 is installed. Then, the handle bar is attached to the nut rod 12 and the support plate 4 of the mount is pressed and tightened. As a result, the hand wheel rotary plate 1 and the packing 11 attached to the roller plate are brought into pressure contact with each other. In this state, the motor is started and the rotational kinetic force is transmitted to the hand wheel rotating plate. The dial 6 has an arbitrary rotational speed, and a forward / reverse switch is provided to obtain a reverse rotational kinetic force.

Embodiments will be described with reference to the drawings. FIG.
Is a front view. Place the hand wheel on the base plate 3. On the other hand, the motor is mounted on a stand composed of 5, 4, and 16. The roller rotating plate 10 is attached to the motor shaft and the packing 1 is attached to it.
1 is provided. The pedestal, the motor, and the roller are integrated, and are inserted into the guide 17 by the slide rod 16 and placed on the guide 3. Then, the handle bolt 13 is used to press and tighten. In this case, the guide plate 18 and the sub guide plate 19 are provided so that the hand wheel cannot move. The roller is fastened to the motor shaft with pin 15. Use the 6 dial to select the speed arbitrarily.
The handle bolt is screwed into the nut rod 12 to make contact with the nut rod 4. This nut rod is connected to the base plate 3.

[0011]

According to the present invention, a conventional hand wheel for exclusive use of hand rotation is automatically rotated by a motor, and has the following effects.

[0012] If the pottery is produced while being rotated by hand, the action of turning the pottery becomes a pain other than the making action. In this case, automatic rotation will make it easier.

By turning the wheel by hand, the concentration on the product is reduced. In addition, the stability of the hand during the production process becomes unstable, and the product is hindered. In this case, the automatic rotation allows you to concentrate completely on the product. As a result, only the production operation is performed, the hand can maintain a stable state for a long time, and an effect of maintaining a completely concentrated state can be obtained.

Since a self-rotating rokuro can be easily used on a desk, it is very easy for amateurs and other potters to use.

Since the rotation speed can be arbitrarily selected, it can be easily manufactured according to the product or the process condition, and the same effect can be obtained by using forward and reverse rotation. In addition, it has the effect of being easier to use depending on the hand.

By selecting the size of the rotating roller plate and replacing it, it is possible to produce a large work protruding from the wheel without any problem.
