As a pottery was a creation that only a few experts called potters performed, the potter's wheel device used was only for the large and heavy professional, but these days, the retirement of the so-called post-war baby boomers, the new life is worthwhile. The pottery was also spotlighted as an easier hobby.

Therefore, in recent years, such as the "portable simple electric potter's wheel converter" described in Japanese Unexamined Patent Publication No. 2002-361615 and the "pottery electric potter's device for ceramics" described in Japanese Patent Application No. 3072207, the compact, lightweight and convenient potter's wheel Although the device has been developed, since it is a simple driving method in which the rollers installed on the rotating shaft are brought into contact with or pressed against the side of the table, both the electric and manual rotations are possible, but the contact and the pressing are insufficient. There was a problem that unevenness occurred.

In addition, when rubber is used for the roller part, maintenance of the rubber may occur due to the abrasion of the rubber due to abrasion of the rubber, or the ceramic clay may enter the abutting part or the pressing part, which may interfere with the rotation. There was a hassle.

In recent years, even when portable potter's wheel apparatuses are being developed, there is almost no consideration in terms of storage properties. Therefore, it is still insufficient to infiltrate ceramics into homes as an easy hobby and entertainment.

Moreover, since the conventional potter's wheel apparatus has only the function as a ceramic tool, and it could not be used for other uses, it lacked interest.

Appearance of the device

First, the external elements of the ceramic potter's wheel apparatus according to the present invention will be described. 1 is a perspective view showing the appearance of an embodiment of the present invention.

The housing 1 may be made of any material. However, since some weight is required for the table, the housing 1 is preferably a lightweight resin material in order to reduce the weight of the entire apparatus. In addition, although not limited to the shape of the housing 1, at least one side of the side part is planar shape so that the whole apparatus may be stored upright. Moreover, the display part 2 for displaying the weight of the ceramic member placed on the table is provided in any one part of the housing 1. In addition, the display unit 2 displays not only the weight but also the rotational speed of the table and the torque applied to the table.

Table 3 is set horizontally on the upper part of the housing 1, and the material does not matter, but since some weight is required at the time of manual rotation, employ | adopting lightweight and antirust material, such as aluminum, is preferable. . Moreover, in this invention, since it also has a function as a millstone, in that case, removal is possible so that Table 3 can be replaced with bedstone.

The circular side wall 4 which has a diameter larger than the table 3 is provided in the peripheral part of the table 3 on the housing 1, and the receiving groove 5 is formed between the table 3 and the side wall 4 by this. The receiving groove 5 may be a dish that receives a granulated or powdered object when used as a millstone described later, in addition to receiving a member or a tool that has fallen from the table 3 during the creation of a ceramic art.

In the illustrated embodiment, the sleeve portion 6 has an integral configuration in which a part of the side wall 4 extends, but is not necessarily limited thereto. In addition, the side wall 4 and the sleeve part 6 can be separated from the housing 1 in the type which has a function as a millstone mentioned later.

From a part of the housing 1, the operation lever 7 for raising and lowering the joint 13 protrudes. As will be described later, since the electric potter's wheel and the manual potter's wheel are switched by the vertical movement of the joint 13, the user switches the operation lever 7 as desired.

Internal structure of the device

Next, the internal elements of the ceramic potter's wheel apparatus according to the present invention will be described. 2 is an internal structural diagram showing a state of use as the electric potter's wheel of the present invention, and FIG. 3 is an internal structural diagram showing a state of use as a manual potter's wheel of the present invention.

First, the state using this apparatus as an electric potter's wheel is demonstrated.

The table 3 is connected to the rotating shaft 9 with the bearing 8 interposed, and as shown in FIG. 3, the several spline groove 10 is formed in the front-end | tip part. In the illustrated embodiment, although the table 3 and the rotating shaft 9 are connected with the bearing 8 in between, a spline groove is formed at the tip of the shaft by using a table with a slightly longer shaft without using the bearing 8. You may also

On the rotation shaft 12 of the motor 11, a bias spring 14 is fitted to abut the joint 13 located above and pushed upwards thereof, and a plurality of spline grooves are formed at the leading end thereof. In addition, the spline groove on the rotating shaft 12 is engaged with the groove formed in the joint 13, and thus is not shown in the drawing.

The joint 13 is for connecting the rotary shaft 9 of the table 3 and the rotary shaft 12 of the motor 11 on the same axis, and the plurality of grooves 15 meshing with the spline grooves 10 formed on both the rotary shaft 9 and the rotary shaft 12 have an inner side thereof. It is formed in.

Therefore, by operating the operating lever 7 to bring the cam 16 into contact with the joint 13 and pushing it downward, the engagement between the spline groove 19 of the rotary shaft 9 and the groove 15 of the joint 13 is released, and the rotating shaft of the motor 11 is released. No connection with 12.

In the state where this apparatus is commonly used as an electric potter's wheel, as shown in FIG. 2, since the cam 16 is not in contact with the joint 13 and the joint 13 is pushed upward by the bias spring 14, the spline of the rotary shaft 9 The groove 10 and the groove 15 of the joint 13 and the spline groove 15 of the rotary shaft 12 of the motor 11 and the groove 15 of the joint 13 are all engaged, and the rotary shaft 9 and the rotary shaft 12 are connected on the same axis. Therefore, the drive of the motor 11 is transmitted to the rotating shaft 9, and the table 3 rotates in synchronization. Since the rotating shaft 9 and the rotating shaft 12 are coaxial, they rotate stably without generating rotation unevenness.

In the state where this apparatus is used as a manual potter's wheel, as shown in FIG. 3, since the cam 16 abuts against the joint 13 and is pushed downward by the operation of the operation lever 7, the spline groove 10 and the joint of the rotary shaft 9 are jointed. The engagement of the groove 15 of the 13 is released, and the rotary shaft 9 and the rotary shaft 12 of the motor 11 are disconnected. Therefore, the drive of the motor 11 is not transmitted to the rotary shaft 9, and since the table 3 does not rotate, the user can rotate the table 3 manually.

Moreover, although the weight sensor 17 for measuring the weight of the ceramic member etc. which were placed in Table 3 is provided and shown in the vicinity of the joint 13 in drawing, it does not identify the mounting position. In the present invention, the weight sensor needs to function in both the electric potter's wheel and the manual potter's wheel, but due to the structural limitation that the rotary shaft 9 and the rotary shaft 12 are connected or disconnected on the same axis, The sensor 17 is provided, and the calculation process which removes the weight of the whole housing from the gross weight is performed, and the weight of the ceramic member etc. which were placed in Table 3 is measured.

Device Electrical structure

Next, the electrical components of the ceramic potter's wheel apparatus according to the present invention will be described. 4 is a block diagram showing the electrical structure of the present invention.

The motor driver 18 for controlling the drive of the motor 11 and the control block 19 for processing various data are all connected to the power supply block 20 to receive electric power. In addition, the motor driver 18 is connected to the control block 19 to control the rotation.

The operation mode switch 21 has at least three modes in which the apparatus is used as a potter's wheel, when it is used as a millstone, and when measuring the weight of a member or the like placed on a table. Switching is enabled by the switch installed in the.

The speed setter 22 is a device for adjusting the rotational speed of the table 3, and it is possible to shift by a switch provided in any one part of the housing 1. The speed setting includes a step shift type for fixing at a plurality of speeds or a continuously variable type for selecting a desired speed. In addition, the rotation speed of the table 3 is displayed on the display portion 2.

The foot switch 23 is a device which can turn ON / OFF and speed change of the rotation of Table 3 by foot, and, in addition to the ON / OFF switch and the shift switch provided in the main body, it can be selected optionally according to a user's preference.

The connector sensor 24 detects the vertical movement of the joint 13 shown in FIGS. 2 and 3, and always monitors the connection between the joint 13 and the rotary shaft 9 or the rotary shaft 12, that is, the connection and disconnection between the rotary shaft 9 and the rotary shaft 12. Doing. If any problem occurs, the error signal is sent to the control block 19. The control block 19 displays the fact on the display unit 2, and performs control such as stopping the driving of the motor 11. FIG.

The torque sensor 25 detects the torque applied to the table 3, and always measures the torque state during the rotation of the table. The measured torque is displayed on the display section 2 together with the rotational speed of table 3 or separately.

As described above, the weight sensor 17 can be operated by the switch operation of the operation mode switch 21, and detects the weight of the ceramic member and the like placed on the table 3. The detected signal is computed in the control block 17, and the weight thereof is displayed on the display portion 2. FIG.

As a millstone Form of use

Next, since the ceramic potter's wheel apparatus which concerns on this invention has the function as a millstone besides a potter's wheel, the embodiment is demonstrated. 5 is a schematic view showing an embodiment as millstone of the present invention.

In the form in which the apparatus according to the present invention is used as a millstone, as shown in FIG. 5, the table 3 and the side wall 4 and the sleeve portion 6 are separated from the housing 1, and the bed stone 26 replacing the table 3, the lid 27, and the like. The runner stone unit which consists of the runner stone 28 attached to the back surface is attached. In addition, in order to eliminate the trouble of detachment, the side wall 4 and the sleeve part 6 may be integrally formed.

In more detail, the bed stone 26 is formed in the spline grooves and the joints 13 formed on both the rotary shaft 9 and the rotary shaft 12 of the motor 11, as shown in FIG. The groove 10 formed is engaged, and the drive of the motor 11 is in a state of being transmitted to the bed stone 26.

The runner stone 28 of the runner stone unit is attached to the rear surface of the cover body 1 so that the cover body 27 is covered with the upper part of the housing 1 so as to properly overlap with the bed stone 26. Moreover, in order to prevent an accident and a problem, the cover body 27 has a shape which covers the whole millstone in the state which covered this to the upper part of the housing 1, and is not moved by rotation of the bed stone 26. It is preferable to be able to fix at the contact part with the housing 1.

As the fixing means of the lid 27, a recess is provided in the lower end of the lid 27, and the housing 1 is provided with a groove provided with a stopper to engage the recess, and does not move in a state where the lid 27 is covered in the upper portion of the housing 1. The movement may be suppressed by setting it as the structure or having the cover body 27 twisted in the upper part of the housing 1, and it does not limit about the fixing means.

The upper part of the cover body 27 is provided with the adjustment tool 29 which can adjust the height of the runner stone 28 attached to the back surface. In the illustrated embodiment, the adjusting mechanism 29 is a dial type that rotates to the left and right, and the right side is widened with the bed stone 26 by turning to the right, and the left side is narrowed with the bed stone 26 by turning to the left. As a result, the buckwheat, coffee beans, tea, etc. can be made into desired thickness by changing the pressure which adjusts the height of the runner stone 28 and the space | interval with the side bed stone 26 using the adjusting tool 29.

EMBODIMENT OF THE INVENTION Hereinafter, the Example at the time of carrying out ceramic art using the ceramic potter's wheel apparatus which concerns on this invention is demonstrated. Fig. 6 is a flowchart showing the procedure in the case of carrying out ceramic art using the present invention.

Since the flowchart shown relates to the procedure in the case of using the present invention as a potter's wheel, the operation mode switch 21 is selected in advance by the changeover switch. First, when a user performs pottery using the potter's wheel apparatus according to the present invention (" start " in the drawing), the speed setting switch of the speed adjuster 22 is set in advance so that the table 3 does not suddenly rotate at high speed by turning on the power. By using this, the rotational speed is set to the minimum ("rotational speed" 0 "" in the drawing). In addition, you may control electrically so that Table 3 may not rotate immediately after power supply.

Subsequently, the user selects whether to use the apparatus as an electric potter's wheel or as a manual potter's wheel. When selecting the electric potter's wheel, the operation lever 7 is switched to the 'electric potter's side' (the `` automatic rotation '' in the drawing). ). Then, the contact and the press of the cam 16 and the joint 13 provided at the tip of the operating lever 7 are released, and the joint 13 moves upward by the bias spring 14, so that the spline groove 10 and the groove 15 of the joint 13 are rotated. Is engaged and is connected on the same axis as the rotating shaft 12 of the motor 11.

Therefore, when the power is finally turned on ("power on" in the drawing), ceramic members such as clay are placed on the table 3 to prepare for creation. If the weight of the clay to be used is determined, switch the switch of the operation mode switch 21 to "weight measurement", and adjust the amount of clay so that it becomes the desired weight while watching the display part 2. Adjust

After the adjustment of the amount of clay is finished, the switching switch of the operation mode switch 21 is again changed to `` green '', and then the desired rotation speed of the table 3 is set by the setting switch of the speed adjuster 22 ( Rotational speed setting ”). When the rotational speed of Table 3 is set, the connector sensor 24 automatically detects the connection state between the rotary shaft 9 and the joint 13 (" shaft connection " in the drawing), and when it is confirmed that no problem occurs, Table 3 starts the rotation. (`` Start of rotation, speed increase '' in the drawing).

In addition, the connector sensor 24 always monitors the connection between the rotary shaft 9 and the joint 13 and the connection between the rotary shaft 12 and the joint 13, and sends a signal to the control block 19 when any problem occurs. An error display is issued to the display unit 2, and control such as stopping the rotation of the table 3 is performed. At that time, it is checked whether or not the rotation of Table 3 is minimum ("rotation speed" 0 "" in the drawing), otherwise control is performed to minimize the rotation speed ("rotation setting" 0 "" in the drawing). .

In this way, when the table 3 starts to rotate and reaches the set speed ("rotated at the set speed" in the drawing), the user adds creation to the clay placed on the table 3 ("pottery work" in the drawing). In order to change the rotational speed of Table 3 on the way, operate the setting switch of the speed adjuster 22 to change to the desired speed. In addition, since the setting switch employs a continuously variable type, the rotation speed can be finely adjusted.

During the creation of the ceramic art, since the rotational speed and torque of the table 3 can be displayed on the display portion 2, the user can adjust the speed according to the rules while checking the display of the display portion 2. In addition, at the time of creation, since both hands cannot be used freely, the foot switch 23 can be connected to rotate, stop or set the speed of the table 3 by foot.

When the creation of the ceramic art is completed, the rotation speed is set to the minimum using the setting switch of the speed adjuster 22 ("rotation speed" 0 "" in the drawing), and the rotation of the table 3 is stopped (the rotation stop in the drawing). ), The power is turned off ("power off" in the drawing), and a series of processes are completed ("job end" in the drawing).

On the other hand, when the manual potter's wheel is selected at the time of selecting whether to use the apparatus as the electric potter's wheel or the manual potter's wheel, the operation lever 7 is switched to the 'manual potter''s side ('manual rotation' in the drawing). Then, the cam 16 provided at the tip of the operating lever 7 abuts against the joint 13 and pushes the joint 13 downward against the bias spring 14, so that the engagement between the spline groove 10 of the rotary shaft 9 and the groove 15 of the joint 13 The shaft is released ("shaft disconnected" in the drawing) and is disconnected from the rotating shaft 12 of the motor 11.

In this way, when the connection between the rotary shaft 9 and the joint 13 is released, the user can rotate the table 3 with his own hands ("manual rotation" in the drawing), so that the creation is added while the table 3 is manually rotated (drawings). Pottery work). In the meantime, when it is necessary to rotate the table 3 automatically, the operation lever 7 may be operated to switch to the "electric potter's wheel" side ("shaft connection" in the drawing). When the creation of the pottery is completed, in the case of the manual potter's wheel, the power supply does not need to be turned off, and thus the work process is finished as it is (finished work).

In addition, in the case of using the present invention as a millstone, in the present invention, the runner stone unit comprising the upper cover 27 and the runner stone 28 mounted on the rear surface thereof is used to rotate the bed stone 26 and grind it to powder. The structure is remarkably different from the general millstone which rotates a stone and grinds to powder.

Regarding the rotation of the bed stone 26, as in Table 3, a rotary shaft having a spline groove is connected to the tip, and the selection of the "electric potter's wheel" by the operation of the operation lever 7, that is, to the spline groove and the joint of the rotary shaft The grooves formed are engaged to be used while being connected on the same axis as the rotating shaft 12 of the motor 11. However, in the case of use as a millstone, since manual rotation of the bed stone 26 is impossible, there is usually no "manual potter's wheel" for disconnecting the connection between the rotary shaft and the joint.

At the time of use as a millstone, the process of attaching a runner stone unit mainly to the above-mentioned use process as a potter's wheel, and the process of height adjustment of the runner stone 28 by the adjustment tool 29 are added, and incidentally, buckwheat, coffee beans, tea Is added to the inlet 30, and the process of discharging the ground powder from the outlet 31 is added.

Since the present invention is a ceramic potter's potter's wheel, in particular, a ceramic potter's wheel having excellent convenience, storage properties, and functionality, it is suitable not only for professional use but also for use in homes. Therefore, people who retire from work or those who use pottery as a hobby can use it as a tool for enjoying leisure.
