Description

  The present invention relates to a stirring and defoaming apparatus capable of stirring and defoaming an object to be processed accommodated in a container.

  Conventionally, as this kind of agitation / deaeration apparatus, a container for containing an object to be processed is provided on a rotary table, and the container is not only revolved by the rotation of the rotary table, but the container itself rotates on the rotary table. What is comprised so that it may also rotate by this is known. In such a stirring and defoaming device, a centrifugal force acts on the object to be processed in the container by revolving the container, and the object to be processed is pressed against the inner wall surface of the container by the centrifugal force. It is possible to separate the bubbles contained in the processed material from the processed material and to degas it. Furthermore, by rotating and rotating the container, the processed material is rotated in a state where the centrifugal force due to the rotation is applied. And can be stirred by applying a stirring force.

  By the way, as such an agitation deaerator, an apparatus configured to start the rotation of the container at the same time as the rotation of the rotary table and the rotation of the container has already been proposed (for example, Patent Document 1). reference).

  In such a stirring and defoaming device, since the revolution and rotation of the container are started at the same time, the centrifugal force due to the revolution and the stirring force due to the rotation are applied to the treatment object from the start of the treatment of the treatment object. be able to. Therefore, the object to be processed is, for example, two kinds of materials having a large specific gravity difference (specifically, powder material and liquid material, for example, material having a specific gravity of 1.5 or more, particularly alumina powder which is ceramic material and specific gravity of 0.9 to (Silicon, which is a liquid material of about 1.1), a material having a high specific gravity (powder material) is compressed into one place in the container, and the whole or part of the material is not solidified and centrifuged. The material to be processed can be stirred and defoamed by flowing with force and stirring force.

Japanese Patent No. 3211335

  However, when the object to be processed is made of, for example, two kinds of materials having a small specific gravity difference (specifically, a plurality of liquid materials, for example, two kinds of epoxy materials), the centrifugal force and the flow start the treatment. When acting on the object to be processed from the point in time, the object is entrained in the air when the centrifugal force is not sufficiently applied to each material (liquid material), that is, the rotation starts from the low revolution stage (low speed stage). In other words, so-called “bubble chewing” occurs, which makes it impossible to sufficiently stir and degas. In particular, when the object to be treated is an epoxy material, the air once entrained is subdivided and is difficult to escape from the object to be treated.

  By the way, in order to prevent "bubble chewing" in the workpiece made of two kinds of materials having a small specific gravity difference, the container rotation is started after the revolution speed of the container reaches a predetermined speed. At the start stage, it is conceivable that only the centrifugal force due to revolution acts on the workpiece, but in such a configuration, two types of materials having a large specific gravity difference (specifically, powder materials and liquid materials) In this case, since the stirring force due to the rotation of the container does not act on the object to be processed until the revolution speed of the container reaches a predetermined speed, the object to be processed is compressed in one place in the container, and the whole or a part thereof is It will solidify and it will not be possible to sufficiently stir and degas.

  Therefore, the present invention has been made in view of such a situation, and the object of the present invention is to provide a stirring and defoaming apparatus that can perform good stirring and defoaming regardless of the object to be processed. There is.

  That is, the stirring and defoaming apparatus of the present invention is provided with a container for storing an object to be processed in order to solve the above-described problem, and the container is a stirring and defoaming apparatus configured to perform both revolution and rotation. A rotation start time setting unit is provided for setting the rotation start time so that the rotation of the container is started at an arbitrary time after the revolution of the container is started.

  In the stirring and defoaming apparatus having the above configuration, the rotation start time setting means determines the rotation start time with respect to the revolution of the container according to the type and property of the constituent material of the workpiece to be stirred and defoamed. It can be set at an arbitrary time after the revolution starts. Therefore, it is possible to perform so-called “foam biting” and solidification of the whole or a part of the object to be processed, and to perform a good stirring and defoaming process for any object to be processed.

  In addition, the rotation start time setting means may start the rotation of the container at an arbitrary time after the rotation start time setting means reaches a predetermined rotation speed after the rotation of the container is started. It may be a means for setting the start time of the rotation.

  According to the above configuration, the rotation start time setting means determines the rotation start time for the container revolution according to the type and nature of the constituent material of the object to be agitated and defoamed, and the predetermined rotation is started. It can be set at any point in time until the revolution speed is reached. Therefore, it is possible to perform so-called “foam biting” and solidification of the whole or a part of the object to be processed, and to perform a good stirring and defoaming process for any object to be processed.

  Further, the rotation start time setting means is rotation start time data relating to the rotation start time of the container, and a rotation start time data storage means for storing a plurality of rotation start time data having different start times; A rotation start time data selection means for selecting one of the plurality of rotation start time data stored in the rotation start time data storage means and setting the selected as the rotation start time of the container; Good.

  According to the above configuration, the rotation start time data selection means selects one of the plurality of rotation start time data stored in the rotation start time data storage means, and sets the start time of the selected rotation start time data. Since the container is set as the rotation start time, the rotation start time can be easily and quickly set.

  The plurality of rotation start time data are the first rotation start data that starts rotation when the container reaches a predetermined revolution speed, and the rotation start when the container starts rotating. Second rotation start data, and the rotation start time data selection means may be configured to select either the first rotation start data or the second rotation start data.

  According to the above configuration, for example, when a material having a large specific gravity difference is agitated, the second rotation start data is selected by the rotation start time data selection means. For example, when a material having a small specific gravity difference is agitated, Since the first rotation start data can be selected by the start point data selection means, the rotation start point data (rotation start data) can be quickly selected.

  The container further comprises stop control means for decelerating and stopping the revolution and rotation of the container from an operating state in which the container is operating at a predetermined revolution speed and a predetermined rotation speed. The deceleration start time and stop time of the rotation may be set so that the deceleration of the rotation starts and stops during the period from the start of the deceleration to the stop.

  According to the above configuration, the revolution starts to decelerate the deceleration start point and stop point of rotation with respect to revolution according to the types and properties of the plurality of materials constituting the workpiece to be stirred and defoamed by the stop control means. It can be set to an arbitrary point in time from the start to the stop. Therefore, whatever the object to be processed is, when the container stops at a predetermined revolution speed and a predetermined rotation speed and stops, so-called bubble biting occurs in the object to be processed, It is possible to prevent the whole or part of the container from being hardened by being compressed at one place in the container and to perform a good stirring and defoaming treatment.

  In the stirring and defoaming apparatus according to the present invention, the start time of the rotation is set so that the rotation of the container is started at an arbitrary time from the start of the rotation of the container to the predetermined rotation speed. By providing the rotation start time setting means, it is possible to accurately set the rotation start time with respect to the revolution of the container for any object to be processed, and to perform good stirring and defoaming. There is an effect.

  Hereinafter, an embodiment of a stirring and defoaming apparatus according to the present invention will be described in detail with reference to the drawings.

  In FIG. 1, the stirring deaerator 1 in this embodiment is shown. The agitation / deaeration apparatus 1 is an apparatus that can agitate and deaerate an object to be processed made of a plurality of materials. Examples of the object to be processed include a material to be stirred that does not like air bubbles such as medical materials, electronic component materials, and liquid crystal materials, and offset ink used in an offset printing machine.

  A stirring and defoaming apparatus 1 shown in FIG. 1 includes an upper open type casing 2 having an opening 2K formed at the upper end, and a main body 3 accommodated in the casing 2. A plate-like cover member K having two openings K1 and K2 for exposing an upper portion of a container 5 (described later) and a rotary handle H for moving the weight 9 is provided on the upper portion of the main body 3. .

  As shown in FIG. 2, the main body 3 is configured to be rotatable about the revolution axis X1, and to be able to accommodate the workpiece, and is installed on the table 4 around the rotation axis X2. A container 5 that can rotate and can revolve by rotating around the revolution axis X 1 of the table 4, a rotation drive mechanism 6 that rotates the container 5 on the table 4, and a table 4 that rotates the container 5. And a revolving rotation drive mechanism 7 for revolving. On the table 4, there is provided a balance adjusting device B that can move by the centrifugal force generated by the revolution of the container 5 or both the revolution and the rotation and balance the position of the center of gravity of the container 5. I have. Since the balance adjusting device B is the same as that shown in Japanese Patent Application Laid-Open No. 2011-36805, detailed description thereof is omitted.

  The table 4 includes a central portion 4A connected to the support shaft 8 on which the revolution axis X1 is set, a horizontal portion 4B located outside the central portion 4A and lower than the central portion 4A, and the horizontal portion 4B, and an inclined portion 4C formed with an inclined surface 4c which is formed continuously on the outer side in the rotational radial direction of 4B and is located on the upper side toward the outer side in the rotational radial direction. The table 4 is configured such that the container 5 can be attached to the inclined surface 4c of the inclined portion 4C so as to be rotatable around the rotation axis X2. Specifically, the inclined surface 4c of the inclined portion 4C is provided with a rotating member 5A in which the container 5 can be detachably installed and a circumferential groove 5M is formed in the lower portion. Further, the table 4 is provided with a weight 9 constituting the balance adjusting device B in the horizontal portion 4B so that the table 4 is arranged substantially symmetrically with the container 5 in the rotational radial direction with respect to the revolution axis X1. The weight 9 is configured to be movable along the rotational radial direction of the table 4 by operating a rotary handle H provided at the upper end thereof. Moreover, the rotation axis X2 which is a rotating shaft of the container 5 is inclined so as to approach the revolution axis X1 side of the table 4 toward the upper end side.

  The revolving rotation drive mechanism 7 is configured to be externally fitted to a revolving electric motor 7 and a drive rotation shaft (not shown) of the electric motor 7 so as to rotate integrally, and a revolving shaft core X1 is set. A support shaft 8 is provided. A central portion 4 </ b> A of the table 4 is connected to the upper end of the support shaft 8.

  The container 5 includes a bottomed cylindrical main body 51a having one end opened, and a lid 51b that can seal the opening of the main body 51a.

  The rotation drive mechanism 6 drives the revolution electric motor 7 to drive the pulley 11 that rotates with the support shaft 8, and the pulley 11 and the rotation member 5A to transmit the rotational force of the pulley 11 to the rotation member 5A. The transmission belt 12 is wound around the groove 5M. The pulley 11 is formed with grooves 11A and 11B at the top and bottom, the rotating member 5A is connected to the upper groove 11A via the transmission belt 12, and the transmission groove 13 is connected to the lower groove 11B. A powder brake 14 is connected.

  The transmission mechanism 13 is a transmission that interlocks and couples a load pulley 15 that is attached to an output shaft 14A that protrudes in a horizontal direction from the powder brake 14 so as to be integrally rotatable, and a load pulley 15 and a lower groove 11B of the pulley 11. Belt 16. By increasing or decreasing the voltage applied to the powder brake 14, the rotational speed of the pulley 11 can be changed by changing the rotational load applied to the pulley 11. Here, the transmission mechanism 13 is a belt-type transmission mechanism using the transmission belt 16, but may be a gear-type transmission mechanism using a gear.

  The stirring and defoaming device configured as described above is provided with a control device U (see FIG. 3), and is controlled and operated by the control device U. Here, the operation will be described. First, when the control device U drives the electric motor 7 for revolution in a state where the voltage applied to the powder brake 14 is 0 and the output shaft 14A is free (rotatable), the rotation is transmitted via the support shaft 8. While the table 4 is rotated by being transmitted to the table 4, the load pulley 15 is free (rotatable). Therefore, the pulley 11 connected to the load pulley 15 via the transmission belt 1 is supported by the support shaft 15. The transmission belt 12 is not driven to rotate relative to the rotation of the table 4. As a result, the container 5 does not rotate but only revolves, and centrifugal force is applied to the object to be processed in the container 5 to separate the bubbles contained in the object to be processed from the object to be degassed. be able to.

  Contrary to the above, when the control device U applies a set voltage to the powder brake 14 and drives the electric motor 7 for revolution with the output shaft 14A fixed in a non-rotating state, for example, the rotation is supported by the support shaft. 8 is transmitted to the table 4 via 8 and the table 4 rotates, while the load pulley 15 is fixed in a non-rotating state, and therefore the pulley 11 connected to the load pulley 15 via the transmission belt 16. However, the transmission belt 12 is driven to rotate relative to the rotation of the table 4 regardless of the rotation of the support shaft 8, and the rotation drive is transmitted to the rotating member 5A. As a result, the container 5 not only revolves but also rotates, and the object to be processed is caused to flow by rotation while being pressed against the inner wall surface of the container 5 by the centrifugal force due to the revolution, and the contained bubbles are degassed. Can be stirred evenly. The container 5 is set to rotate in the direction opposite to the rotation direction of the table 4 and its maximum rotation speed is set to the same speed as the maximum rotation speed of the table 4. By controlling the rotation of the rotation motor provided at, the ratio between the revolution speed and the rotation speed can be set to a ratio other than 1: 1 (for example, 1: 1.5).

  Here, the stirring and defoaming device in the present embodiment is configured such that the timing at which the control device U starts rotation can be changed by changing the timing at which the voltage is applied to the powder brake 14. The configuration of the control device U will be described with reference to FIG.

  The control device U includes a rotation start time setting unit 17 that sets a time point at which the container 5 starts to rotate, and a stop control unit 18 that stops the rotation and revolution of the container 5 that is rotating and revolving.

  The rotation start time setting means 17 is a means for setting the time point at which the rotation starts so that the rotation of the container 5 is started at an arbitrary time after the revolution of the container 5 is started until the predetermined rotation speed is reached. It is.

  The rotation start time setting means 17 is rotation start time data for storing a plurality of rotation start time data (here, two) that are different from the rotation start time data regarding the rotation start time of the container 5. Rotation start time data for selecting one of the two rotation start time data stored in the time data storage means 19 and the rotation start time data storage means 19 and setting it as the rotation start time of the container 5 And a selection unit 20.

  The two rotation start time data are the first rotation start data (see FIG. 4A) in which the time when the container 5 reaches the predetermined revolution speed v1 and the rotation start time (see FIG. 4A), and the revolution of the container 5 is started. This is second rotation start data (see FIG. 4 (b)) with the time point as the rotation start point, and the rotation start point data selection means 20 can select (switchable) one of these two start data. It is configured.

  The stop control means 18 is a means for decelerating and stopping the revolution and rotation of the container 5 from the operating state in which the container 5 is operating at a predetermined revolution speed and a predetermined rotation speed, and more specifically, It is a means for setting the deceleration start time and stop time of the rotation of the container 5 so that the deceleration of the rotation starts and stops between the start and stop of the revolution deceleration.

  Further, the stop control means 18 stores a plurality (two in this case) of stop control data including deceleration start time data relating to the time when the rotation of the container 5 starts to decelerate and stop time data relating to the time when the rotation is stopped. For selecting one of the stop control data storage means 21 and the two stop control data stored in the stop control data storage means 21 and setting them as the deceleration start time and stop time of rotation of the container 5 Stop control data selection means 22.

  Here, the two stop control data are data for starting the deceleration when the container 5 starts to decelerate from the predetermined revolution speed, and the stop time data is for starting the deceleration of the rotation. Then, the first stop control data (see FIG. 4A), which is data for stopping rotation immediately, and the deceleration start time data start the deceleration of rotation when the container 5 starts decelerating from a predetermined revolution speed. The stop time data is second stop control data (see FIG. 4B) which is data for stopping the rotation when the revolution stops. The stop control data selection means 22 is configured to be able to select (switchable) any one of these two stop control data.

  The stirring and defoaming device in the present embodiment is configured such that the driving and stopping of the electric motor 7 and the powder brake 14 can be controlled by the control device U configured as described above. Next, the control device U The control by will be described.

  First, the operator selects the first rotation start data and the first stop control data by operating, for example, a selection means (for example, a switch button or a switch) provided on an operation panel (not shown) of the control device U. A case of performing (switching) will be described. When such a selection is made, the control device U sends a signal for starting driving the electric motor 7 for revolution with the voltage supplied to the powder brake 14 to 0 based on the first rotation start data. It outputs to a voltage supply part and the electric motor 7, respectively. If it does so, as shown to Fig.4 (a), only the revolution will start, without starting rotation of the container 5. FIG. Then, when the revolution is accelerated and the revolution speed reaches the predetermined speed v1, the control device U outputs a signal for supplying a voltage to the powder brake 14 to the voltage supply unit. Then, the powder brake 14 is activated and the container 5 starts to rotate. Further, when the revolution speed reaches the predetermined speed v1, the control device U outputs a signal for performing a constant speed rotation at the predetermined revolution speed v1 (that is, a constant speed rotation of the table 4) for a predetermined time. In the case shown in FIG. 4 (a), the signal output to the voltage supply unit of the powder brake 14 is a state in which the output shaft 14A is fixed in a non-rotating state after a predetermined time has elapsed since the powder brake 14 was activated. Is a signal that is controlled so that Therefore, when the output shaft 14A is fixed in the non-rotating state, the rotation speed is the same speed v1 as the revolution speed v1. When the rotation speed of the container 5 reaches the same speed v1 as the revolution speed, the control device U outputs a signal for supplying a voltage to the powder brake 14 to the voltage supply unit so as to maintain the speed.

  And if the said constant speed rotation is performed for the predetermined time, it will transfer to the stop control which decelerates and stops the revolution and rotation of the container 5. FIG. When the predetermined time has elapsed, the control device U outputs a signal for decelerating the rotation of the electric motor 7 to the electric motor 7 based on the first stop control data, and at the same time, immediately sets the voltage to the powder brake 14 to zero. A signal is output to the voltage supply unit, and as shown in FIG. 4A, the rotation is immediately stopped while the deceleration of the revolution of the container 5 is started. In FIG. 4 (a), the deceleration start point of revolution of the container 5 and the stop point of rotation are the same, but since there is actually a slight time lag, the rotation of the container 5 is limited within a range that can be regarded as substantially the same. The stop point may be shifted to the side (right side in FIG. 4 (a)) after a lapse of time from the start point of revolution deceleration.

  Next, in the agitation defoaming operation, the selection means (for example, a switch button or a switch) provided by the operator having the second rotation start data and the second stop control data on the operation panel (not shown) of the control device U. The case of selecting by operating will be described. When such a selection is made, the control device U outputs a signal for starting driving of the electric motor 7 for revolution while supplying a voltage to the powder brake 14 based on the second rotation start data. And output to the electric motor 7, respectively. As a result, as shown in FIG. 4B, the revolution of the container 5 starts, and at the same time, the rotation starts. In the case shown in FIG. 4B, the signal output to the voltage supply unit of the powder brake 14 is a state in which the output shaft 14A is fixed in a non-rotating state after a predetermined time has elapsed after the powder brake 14 is operated. Is a signal that is controlled so that Therefore, when the output shaft 14A is fixed in the non-rotating state, the rotation speed is the same speed v1 as the revolution speed v1. When the revolution speed and the rotation speed of the container 5 reach the predetermined speed v1, the control device U sends a signal for performing a constant speed rotation at the predetermined speed v1 of the revolution and the rotation for a predetermined time, to the electric motor 7 and the voltage supply unit. Output to.

  And if the said constant speed rotation is performed for the predetermined time, it will transfer to the stop control which decelerates and stops the revolution and rotation of the container 5. FIG. When the predetermined time has elapsed, the control device U outputs a signal for decelerating the rotation of the electric motor 7 to the electric motor 7 based on the second stop control data, and at the same time, gradually increases the voltage to the powder brake 14 over time. A signal to be reduced is output to the voltage supply unit, and as shown in FIG. 4B, the rotation of the container 5 is decelerated at the same deceleration as the revolution of the container 5 to stop the revolution and stop the rotation. Match the time.

  Here, selection of two rotation start data (first rotation start data and second rotation start data) of rotation start rotation data and selection of two stop control data (first stop control data and second stop control data) Is made according to the type and nature of the material constituting the workpiece.

  That is, when the workpiece is made of two types of materials having a small specific gravity difference (specifically, a plurality of liquid materials, for example, two types of epoxy materials having different specific gravity), the first rotation start data and the first stop control. By selecting the data, as shown in FIG. 4A, the rotation is started when the container 5 reaches a predetermined revolution speed based on the first rotation start data. However, only the centrifugal force due to the revolution of the container 5 acts on the object to be treated, and the stirring force due to the rotation does not act. Accordingly, each liquid material having a small difference in specific gravity does not flow greatly in the container 5, and so-called “bubble biting” can be prevented. Moreover, in the stop control, by stopping the rotation immediately at the time of decelerating the revolution of the container 5 performing the revolution and the rotation based on the first stop control data, even during the stop control of the container 5, Only the centrifugal force due to the revolution of the container 5 acts on the object to be treated, and the stirring force due to the rotation does not act. Therefore, each liquid material having a small specific gravity difference can be prevented from flowing largely in the container 5 and so-called “bubble chewing” can be prevented. In particular, the so-called “bubble chewing” is likely to occur when the container 5 is rotating at a low speed while the revolution of the container 5 is being decelerated. It is preferable to set the stop point of this time before the revolution stop point (earlier in time).

  Further, when the object to be processed is made of two kinds of materials having a large specific gravity difference (specifically, powder material and liquid material), by selecting (switching) the second rotation start data and the second stop control data. As shown in FIG. 4B, since the revolution and rotation of the container 5 are started simultaneously based on the second rotation start data, the entire region from the bottom surface to the upper end surface of the container 5 by the centrifugal force due to the rotation. The workpiece to be pressed over the entire area can be made to flow as a whole by the stirring force by rotation. Therefore, it is possible to prevent the material (powder material) having a large specific gravity from being compressed in one place in the container and harden the whole or a part thereof and sufficiently perform the defoaming process. In addition, since the container 5 performing revolution and rotation can be simultaneously decelerated and stopped simultaneously based on the second stop control data, the specific gravity is given to one place in the container even during stop control. It can be prevented that a large material (powder material) is compressed and the whole or a part thereof is hardened. In addition, as a combination of two kinds of materials having a large specific gravity difference, a material having a specific gravity of 1.5 or more, particularly a combination of alumina powder as a ceramic material and silicon as a liquid material having a specific gravity of about 0.9 to 1.1. In addition, a combination of carbon powder for electrodes (particle size of several μm to several tens of μm) and a solvent may be used.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  In the embodiment, the two patterns shown in FIGS. 4A and 4B can be switched from the two rotation start data and the two stop control data, but the two rotation start data and The combination with the two stop control data may be changed so that four patterns are controlled. That is, the two patterns of FIGS. 4A and 4B, the rotation start data (first rotation start data) of FIG. 4A and the stop control data (second stop control data) of FIG. 4B. And a single pattern combining the rotation start data (second rotation start data) in FIG. 4B and the stop control data (first stop control data) in FIG. There may be four patterns.

  In the embodiment, two rotation start data are stored in the rotation start time data storage unit 19 and two stop control data are stored in the stop control data storage unit 21. However, three or more rotation start data are stored. The rotation start time data storage means 19 stores the same, and three or more stop control data are also stored in the stop control data storage means 21, and one rotation start data and one stop control data are selected from among them. It may be a configuration.

  Here, other examples of the rotation start data and the stop control data are shown in FIGS. In FIG. 5 (a), the rotation start data starts rotation from the time when the rotation speed reaches a predetermined speed (the rotation speed is approximately half of the predetermined rotation speed v1). The revolution and rotation are almost the same acceleration. The stop control data is data that starts the deceleration of the rotation from the point when the deceleration of the revolution starts and stops the rotation in a time shorter than the time when the revolution stops (approximately half the stop time of the revolution). The deceleration of rotation is greater than the deceleration of. In FIG. 5B, the rotation start data indicates that rotation and rotation start at the same time, and before the revolution reaches a predetermined revolution speed (when the revolution reaches almost half of the predetermined revolution speed). It is data for which the speed reaches a predetermined rotation speed, and the acceleration of revolution is smaller than the acceleration of rotation. Stop control data is data that starts rotation deceleration after the revolution deceleration starts (when the revolution speed is reduced by almost half) and sets the revolution and rotation to the same stop point. The speed is larger than the deceleration of revolution. As shown in FIG. 5B, in order to make the rotation acceleration larger than the revolution acceleration and the rotation deceleration larger than the revolution deceleration, as shown in FIG. The motor 7 and the electric motor 23 for rotation are used. Further, the rotation start time setting means 17 shown in the embodiment starts rotation of the container 5 at an arbitrary time from the start of rotation of the container 5 until the predetermined rotation speed is reached. In this way, the rotation start time of the container 5 is set. However, the rotation of the container 5 is started at an arbitrary time after the revolution of the container 5 is started and the predetermined rotation speed is reached. The start time of the rotation may be set. In short, as long as the revolution of the container 5 is started, the start time of the rotation of the container 5 may be set at any time.

  Note that the rotation start data and the stop control data are not limited to be stored as separate data, and a plurality of rotation control data obtained by combining one rotation start data and one stop control data are stored and stored. One rotation control data may be selected from among the rotation control data.

  Alternatively, the stop control data may be the same single data, only the rotation start data may be composed of a plurality of different data, and one rotation start data may be selected from the plurality of rotation start data.

  In the above embodiment, the constant speed control is performed when the rotation speed and the revolution speed reach predetermined speeds. However, as shown in FIG. 6A, the rotation speed may be variable. In the graph of FIG. 6A, the waveform of the rotation speed changes so as to wave in the up and down direction at a constant period (wave in a sine wave shape) within the speed range between the speeds v1 and v2. The speed range in which the rotation speed changes is not limited to a certain range, and may be a case where the speed range gradually increases or decreases with time and changes so as to repeat increase and decrease. Moreover, the structure which autorotation repeats normal rotation and reverse rotation may be sufficient. In this case, the ratio of time between forward rotation and reverse rotation can be set in any manner. In FIG. 6 (a), revolution and rotation are executed simultaneously and the stopping time is also the same, but it is not limited to these.

  Further, instead of the constant speed control, it is possible to perform not only the rotation but also the revolution to change the speed. In FIG. 6B, the waveform of the revolution speed also changes so as to wave in the up and down direction at a constant period (waves in a sine wave) within the speed range between the speeds v1 and v2, similarly to the waveform of the rotation speed. Note that the speed range in which the revolution speed changes may also be a case where the speed range gradually increases or decreases with time, or changes such that the increase and decrease are repeated, similar to the speed range of the rotation speed. Moreover, the structure which revolution repeats forward rotation and reverse rotation similarly to autorotation may be sufficient. In particular, a configuration in which the rotation rotates in the normal rotation direction or the reverse rotation direction with respect to the rotation direction of revolution is preferable. In this case, the ratio of time between forward rotation and reverse rotation can be set in any manner. In addition, in FIG.6 (b), revolution and autorotation are performed simultaneously, and the stop time is also made the same, However, It is not limited to these.

  In addition, in order to perform normal rotation and reverse rotation of the revolution or rotation as described above, in addition to the electric motor 7 for revolution, an electric motor 23 for rotation is provided, and the two The electric motors 7 and 23 are driven and controlled.

  Further, in the above-described embodiment, the container 5 is rotated by the revolution electric motor 7 and the powder brake 14 and the voltage supply timing to the powder brake 14 is changed, whereby at least the container 5 with respect to the start point of the revolution. 7 is controlled, but, as shown in FIG. 7, in addition to the electric motor 7 for revolution, an electric motor 23 for rotation is provided, and these two electric motors 7, 23 are connected to each other. The structure which controls the start time of the rotation of the container 5 with respect to the start time of revolution may be performed by driving control. In short, if it is the structure which can control the revolution and rotation of the container 5 separately, the start time of the rotation with respect to revolution can be controlled. However, by using the electric motor 7 and the powder brake 14, the configuration of the apparatus can be simplified and the size can be reduced. On the other hand, by using the two electric motors 7 and 23, the rotation speed is higher than the revolution speed. There is an advantage that the revolution direction and the rotation direction of the container 5 can be freely changed.

  Moreover, in the said embodiment, although the structure which provided the one container 5 on the table 4 was used, the structure which provided the some container 5 on the table 4 may be sufficient.
