It is connected with. 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 on the same axis, they rotate stably without causing uneven rotation.

In a state where the present apparatus is used as a manual wheel, as shown in FIG. 3, the cam 16 comes into contact with the joint 13 by the operation of the operation lever 7, and pushes it downward, so that the spline groove 10 of the rotary shaft 9 and the joint 13 The engagement with the groove 15 is released, and the rotating shaft 9 and the rotating shaft 12 of the motor 11 are disconnected. Therefore, the drive of the motor 11 is not transmitted to the rotary shaft 9 and the table 3 does not rotate, so that the user can manually rotate the table 3.

  In addition, a weight sensor 17 for measuring the weight of a ceramic pottery placed on the table 3 is provided and is shown in the vicinity of the joint 13 in the drawing. Absent. In the present invention, it is necessary to make the weight sensor function both in the case of the electric wheel and the hand wheel, but since there is a structural restriction that the rotating shaft 9 and the rotating shaft 12 are connected / disconnected on the same axis, A weight sensor 17 is provided at the bottom of the housing 1 and the weight of the ceramic member placed on the table 3 is measured by performing arithmetic processing to subtract the weight of the entire housing from the total weight. Is scheduled.

As described above, the weight sensor 17 can be activated by operating the switch of the operation mode switching 21 and detects the weight of the ceramic member placed on the table 3. The detected signal is processed by the control block 17 and its weight is displayed on the display unit 2.
Form of use as a stone mill Next, the potter's wheel apparatus according to the present invention has a function as a stone mill in addition to the potter's wheel, so an embodiment thereof will be described. FIG. 5 is a schematic view showing an implementation state of the present invention as a stone mill.

In the form in which the apparatus according to the present invention is used as a stone mill, as shown in FIG. 5, the table 3, the side wall 4, and the sleeve 6 are removed from the housing 1, and a lower mill 26 instead of the table 3, a lid body 27, The upper die unit composed of the upper die 28 attached to the back surface thereof is attached. In addition, in order to eliminate the troublesomeness of desorption, the side wall 4 and the sleeve part 6 are good also as integral molding.

This form will be described in more detail. As shown in FIG. 2, the lower die 26 is a spline groove formed on both the rotating shaft 9 and the rotating shaft 12 of the motor 11 as in the case of the table 3 used as an electric wheel. And the groove 10 formed in the joint 13 are engaged with each other, and the drive of the motor 11 is transmitted to the lower die 26.

The upper mortar 28 of the upper mortar unit is attached to the back surface of the lid body 1 so as to correctly overlap the lower mortar 26 in a state where the lid body 27 is put on the upper portion of the housing 1. The lid 27 is shaped so as to cover the entire stone mill in a state where the lid 27 is placed on the upper part of the housing 1 in order to prevent accidents and malfunctions, and is moved by the rotation of the lower mill 26. It is desirable to be able to fix the contact portion with the housing 1 so as not to occur.

As a fixing means for the lid 27, a locking portion is provided at the lower end of the lid 27, a groove portion provided with a stopper that engages with the locking portion is formed in the housing 1, and a lid is formed on the top of the housing 1. Further, the movement may be suppressed by adopting a configuration in which the cover 27 is not moved and the lid 27 is screwed into the upper portion of the housing 1, and the fixing means is not limited.

An adjustment tool 29 that can adjust the height of the upper die 28 attached to the back surface of the lid body 27 is provided on the upper portion of the lid body 27. In the illustrated embodiment, the adjustment tool 29 is a dial type that rotates to the left and right. When the adjustment tool 29 is turned to the right, the distance from the lower die 26 is widened, and when turned to the left, the distance from the upper die 26 is narrowed. Yes. As a result, the height of the upper die 28, that is, the distance from the lower die 26 is adjusted using the adjustment tool 29, and the grinding pressure is changed to grind buckwheat berries, coffee beans, tea, etc. with the desired roughness. be able to.

  Examples of performing pottery using the potter's wheel device according to the present invention will be described below. FIG. 6 is a flowchart showing the procedure for performing ceramics using the present invention.

  Since the illustrated flowchart relates to a procedure when the present invention is used as a potter's wheel, the operation mode switch 21 has previously selected the "roller" mode by the changeover switch. First, when the user performs pottery using the potter's wheel apparatus according to the present invention (“Start” in the figure), the speed setting of the speed setting device 22 is set in advance so that the table 3 does not rotate rapidly at high speed when the power is turned on. The rotation speed is set to the minimum using a switch (“rotation speed“ 0 ”” in the figure). Note that electrical control may be performed so that the table 3 does not rotate immediately after the power is turned on.

Subsequently, the user selects whether the apparatus is used as an electric wheel or a manual wheel, but when selecting an electric wheel, the operation lever 7 is set to the “electric wheel” side. Switch (“Auto-rotate” in the figure). Then, the cam 16 provided at the tip of the operating lever 7 and the joint 13 are released from contact and pressure, and the joint 13 is moved upward by the biasing spring 14, so that the spline groove 10 and the joint 13 of the rotary shaft 9 are moved. Are engaged with each other and are connected on the same axis as the rotary shaft 12 of the motor 11.

Therefore, when the power is finally turned on (“Power ON” in the figure), a ceramic member such as clay is placed on the table 3 to prepare for the creation. At that time, if the weight of the clay to be used is determined when performing creation according to the teaching rules, etc., the changeover switch of the operation mode switching 21 is switched to “weight measurement” and the desired weight and Adjust the amount of clay to be.

After adjusting the amount of clay, the changeover switch of the operation mode changeover 21 is changed over to the “roller” again, and then the desired rotation speed of the table 3 is set by the setting switch of the speed setting device 22 (in the figure). “Rotation speed setting”). When the rotational speed of the table 3 is set, the connecting machine sensor 24 automatically detects the connection state between the rotary shaft 9 and the joint 13 (“shaft connection” in the figure), and it is confirmed that no malfunction has occurred. Then, the table 3 starts to rotate (“Rotation start, speed up” in the figure).

The connection machine sensor 24 continuously 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 if any trouble occurs. The control block 19 gives an error display on the display unit 2 and controls the table 3 to stop rotating. At that time, it is checked whether or not the rotation of the table 3 is minimum (“rotation speed“ 0 ”” in the figure), and if not, control is performed to minimize the rotation speed (“rotation setting“ 0 ”in the figure). ").

Thus, when the table 3 starts to rotate and reaches the set speed ("Rotate at set speed" in the figure), the user adds a creation to the clay placed on the table 3 ("Ceramic work" in the figure). . On the way, when it is desired to change the rotation speed of the table 3, the setting switch of the speed setting device 22 is operated to change it to a desired speed. Since the setting switch adopts a continuously variable transmission type, the rotational speed can be finely adjusted.

During the creation of ceramic art, the rotation speed and torque of the table 3 can be displayed on the display unit 2, so that the user can adjust the speed according to the teaching rules while checking the display on the display unit 2. Further, since the freedom of both hands is deprived at the time of creation, the foot switch 23 can be connected, and the table 3 can be rotated / stopped and the speed can be set by the foot.

When the creation of the pottery is completed, the rotation speed is set to the minimum using the setting switch of the speed setting device 22 (“rotation speed“ 0 ”” in the figure), and the rotation of the table 3 is stopped (“rotation stop” in the figure). ), The power is turned off ("Power OFF" in the figure), and a series of steps are completed ("Work End" in the figure).

On the other hand, when selecting whether to use the apparatus as an electric wheel or a manual wheel, the manual lever is switched to the “manual wheel” side (“manual rotation” in the figure). Then, the cam 16 provided at the tip of the operation lever 7 comes into contact with the joint 13 and pushes the joint 13 downward against the biasing spring 14, so that the spline groove 10 of the rotary shaft 9 and the groove 15 of the joint 13 The engagement is released (“shaft separation” in the figure), and the motor 11 is not connected to the rotating shaft 12.

Thus, when the connection between the rotary shaft 9 and the joint 13 is released, the user can rotate the table 3 with his / her hand (“manual rotation” in the figure), so that the table 3 is rotated manually. Add creative work ("Ceramic work" in the figure). If it becomes necessary to automatically rotate the table 3 on the way, the operation lever 7 may be operated to switch to the “electric wheel” side (“shaft connection” in the figure). When the creation of the pottery is completed, it is not necessary to turn off the power in the case of a manual wheel, so the work process is finished as it is (“work end” in the figure).

In addition, in the case where the present invention is used as a stone mill, in the present invention, an upper mill unit comprising an upper lid 27 and an upper mill 28 attached to the back surface thereof is used, and the lower mill 26 is rotated to produce a ground powder. Therefore, the structure is remarkably different from the general stone mill in which the upper mill is rotated to grind the powder.

As for the rotation of the lower die 26, as with the table 3, a rotary shaft having a spline groove formed at the tip is connected, and selection of an “electric wheel” by the operation of the operation lever 7, that is, the spline groove of the rotary shaft The groove formed in the joint meshes with the rotary shaft 12 of the motor 11 and is used on the same axis. However, in use as a stone mill, there is no possibility of manually rotating the lower mill 26, so there is usually no scene of selecting a “manual wheel” that disconnects the connection between the rotary shaft and the joint.

When using as a millstone, the process of attaching the upper mill unit and the process of adjusting the height of the upper mill 28 using the adjustment tool 29 are added to the process of using the potter's wheel. And a step of feeding coffee beans and tea into the inlet 30 and a step of discharging the ground flour from the outlet 31 are added.

  Since the present invention is a pottery wheel for pottery, in particular, a pottery wheel having excellent convenience, storability and functionality, it is suitable not only for full-scale use but also for home use. Therefore, it can be used as a tool for those who have retired from work or who have a hobby of pottery to enjoy their leisure time.
