Each balance load member is rotated around the revolution drive rotation shaft as the revolution rotator 102 rotates. Further, the rotation balance adjusting mechanism 104 adjusts the balance of rotation of the revolution rotator 102 by adjusting the size of the opening angle formed by each of the two straight lines connecting the gravity center position and the revolution center position of each balance load member. A position adjusting mechanism is provided.

The rotation balance adjusting mechanism 104 is provided with a first sensor 104c for detecting the rotation phase of the revolution rotator 102 and a second sensor 104d for detecting the direction or phase of vibration of the revolution rotator 102. Based on the detection signal of the first sensor 104c and the detection signal of the second sensor 104d, the size of the opening angle is automatically set so as to obtain a state in which vibration associated with the rotation of the revolution rotator 102 is minimized. Adjusted.

According to the above-described apparatus, the two

balance load members

For this reason, the rotation balance of the revolution rotator 102 is adjusted by adjusting the size of the opening angle formed by each of the two straight lines connecting the gravity center position and the revolution center position of each

balance load member

However, two

sensors

104c and 104d are used in the rotation balance adjusting mechanism 104, and each sensor has a different detection target. For this reason, if one of the sensors is malfunctioning, there is a possibility that the rotation balance adjustment of the revolution rotating body 102 cannot be realized. Therefore, there is a problem that the reliability of the rotation balance adjusting mechanism 104 is low.

Hereinafter, an embodiment of the stirring and defoaming apparatus according to the present invention will be described. The agitation / defoaming apparatus 1 of this embodiment includes a drive mechanism 2, a revolution mechanism 3, a rotation mechanism 4, a workpiece holding unit 5, a balance mechanism 6, a detection unit 7, a data processing unit 8, and an information display unit 9. .

The driving mechanism 2 includes a motor 21, a driving force transmission mechanism 22, and a rotating shaft 23 as shown in FIG. The driving force transmission mechanism 22 of this embodiment includes a belt 221 and

belt wheels

222 and 222 that are attached to the driving shaft 211 and the rotating shaft 23 of the motor 21 and over which the belt 221 is stretched. With this configuration, the driving mechanism 2 transmits the driving force of the motor 21 to the rotating shaft 23. The rotating shaft 23 is attached to the fixed base 11 supported by the vibration isolator 12 via a bearing 24, and is rotatable about the revolution axis C1.

As shown in FIG. 1, the revolution mechanism 3 includes a rotor 31 configured to be rotatable (revolved) around a revolution axis C <b> 1 that coincides with the center of the rotation shaft 23. The rotor 31 is a metal frame and is fixed to the rotating shaft 23. Therefore, the rotor 31 revolves when the motor 21 is driven. A part of the rotation mechanism 4, the workpiece holding unit 5, and the balance mechanism 6 are attached to the rotor 31. The rotor 31 and the portion attached to the rotor 31 are the revolution rotator R that revolves together. A circular rotor cover 32 that covers the rotor 31 from above and revolves together with the rotor 31 is provided.

The rotation mechanism 4 includes a central pulley 41, a reversing pulley 42, a belt bending pulley 43, a container side pulley 44, a first belt 45, a second belt 46, and a speed reduction mechanism 47. The first belt 45 is stretched around the central pulley 41 and the reverse pulley 42. The second belt 46 is stretched around the reverse pulley 42 and the container side pulley 44. The central pulley 41 is located around the rotation shaft 23 via a bearing 411. For this reason, it can be rotated separately from the rotating shaft 23. The central pulley 41 is decelerated by the speed reduction mechanism 47 and rotates. The reverse pulley 42 has a larger diameter than the central pulley 41 and is located on the radially outer side of the central pulley 41. The reversing pulley 42 is formed with two upper and

lower belt grooves

421 and 422. A first belt 45 that transmits a driving force to the central pulley 41 is hung on the lower belt groove 421, and a second belt 46 that transmits a driving force to the container rotating pulley 44 in the upper belt groove 422. Is multiplied. The container rotation pulley 44 is integrated with the container support part 52 of the workpiece holding part 5. The belt bending pulley 43 is provided to change the extending direction of the second belt 46 from the horizontal (reverse pulley 42 side) to the diagonally upper side (container rotation pulley 44 side).

The deceleration mechanism 47 is integrally formed below the central pulley 41. The reduction mechanism 47 includes a first reduction gear 471 arranged in the horizontal direction, a second reduction gear 472 engaged with the first reduction gear 471 and arranged in the vertical direction, and powder connected to the second reduction gear 472. And a brake 473. The powder brake 473 is configured such that the output shaft 473a is decelerated in proportion to an increase in driving current or driving voltage. By this reduction, the speed (the number of revolutions) of the central pulley 41 can be reduced via the first reduction gear 471 and the second reduction gear 472. With this speed reduction mechanism 47, the rotation speed (number of rotations) of the workpiece holding unit 5 can be adjusted.

The to-be-processed object holding | maintenance part 5 is provided with the container support part 52 attached with respect to the rotor 31 via the bearing 51 so that rotation was possible. A part of the container support portion 52 is located so as to protrude upward from the rotor cover 32. A cylindrical container 53 is disposed on the container support 52. The container 53 is revolved or rotated integrally with the container support part 52 by being fitted to the container support part 52 or disposed via a stopper made of rubber or the like. The container 53 can be installed on the rotor 31 via the container support portion 52. The container 53 includes a main body 531 having an upper opening and a lid portion 532 for closing the opening, and is configured to be able to accommodate an object to be processed. As shown in FIG. 1, the container support 52 is arranged so that the opening of the main body 531 in the container 53 faces obliquely upward on the side of the revolution center C1. As described above, the container 53 can rotate about the rotation axis C <b> 2 and revolves by the rotation of the rotor 31 about the rotation axis C <b> 1.

The balance mechanism 6 is located on the opposite side of the revolution axis with respect to the center of gravity of the container 53 in the workpiece holder 5 in the rotor 31 and is configured to be movable so as to be able to approach and separate from the revolution axis C1. 61 is provided. The balance weight 61 is located at the screw rod portion 62 and the support rod portion 63. The balance weight 61 is movable in the radial direction (X-axis direction) in response to the operator rotating a dial 64 that is partially protruding from the rotor cover 32. Thereby, the center-of-gravity balance position with respect to the container 53 in the to-be-processed object holding | maintenance part 5 in the revolution rotation body R can be adjusted. An indicator 65 is formed to indicate the position of the balance weight 61. As shown in FIG. 3B, the indicator 65 is provided on the left side of the illustrated portion 651 that moves in the X-axis direction together with the balance weight 61, the through hole 652 that passes through the rotor cover 32 and can be visually recognized by the instruction portion 651, A scale portion 653 is provided, which is arranged and has a scale corresponding to the weight of the object to be processed accommodated in the container 53 (the display “Gross Weight” in the drawing).

The detection unit 7 includes an acceleration detection unit 71 and a revolution speed detection unit 72. The acceleration detection unit 71 is positioned on a substrate located below the stirring / deaeration device 1, and an X-axis acceleration detection unit 711 arranged with the detection direction facing the X-axis direction in the horizontal plane direction, and the detection direction Y-axis acceleration detector 712 arranged in the horizontal direction in the Y-axis direction perpendicular to the X-axis direction, and Z-axis acceleration detector 713 arranged in the Z-axis direction, which is the vertical direction. Is provided. The X-axis acceleration detection unit 711 obtains acceleration data having a waveform as shown in FIG. 4A, for example. The Y-axis acceleration detection unit 712 obtains acceleration data having a waveform as shown in FIG. 4B, for example. For example, acceleration data having a waveform as shown in FIG. 4C is obtained by the Z-axis acceleration detection unit 713. Detection by each of the detection units 711 to 713 is performed at a predetermined sampling frequency.

In this embodiment, the acceleration detector 71 is positioned below the fixed base 11 that is the support position of the revolution shaft 23. For this reason, the container 53, the fixed base 11 and the acceleration detecting unit 71 are arranged in the vertical order. With the position of the fixed base 11 (that is, the support position of the revolution shaft 23) sandwiched between the container 53 and the acceleration detector 71, the position can be made substantially symmetrical. Thus, if it is in the relationship of a substantially symmetrical position, the shift | offset | difference of the revolution axis C1 accompanying revolution will become substantially the same by the container 53 side and the acceleration detection part 71 side. Therefore, it is possible to accurately grasp the shaking on the container 53 side using the detection value by the acceleration detection unit 71.

Similar to the acceleration detector 71, the revolution speed detector 72 is located at the lower end of the rotation shaft 23 and the sensor 721 located on the substrate located below the stirring and defoaming device 1, and revolves together with the rotation shaft 23. And a dog 722 that rotates about the axis C1. The revolution speed detection unit 72 can detect the revolution speed of the rotating shaft 23, that is, the revolution speed of the rotor 31 (the revolution speed in this embodiment).

The data processing unit 8 is located on the substrate located below the stirring and defoaming device 1, similarly to the acceleration detection unit 71. The data processing unit 8 includes a data conversion unit 81, a displacement determination unit 82, and a vibration determination unit 83 (see FIG. 8). The data converter 81 includes an X-axis acceleration data detected by the X-axis acceleration detector 711, a Y-axis acceleration data detected by the Y-axis acceleration detector 712, and a Z-axis detected by the Z-axis acceleration detector 713. The direction acceleration data is subjected to Fourier transform (frequency analysis), spectrum data (see FIGS. 5A, 6A, and 7A) regarding the relationship between the frequency and the amplitude in each axis, and the frequency and phase in each axis direction. Phase component data (see FIGS. 5B, 6B, and 7B) is obtained. By this Fourier transform, it is possible to separate noise components and components necessary for deviation determination from each axis acceleration data. The conversion in the data converter 81 is performed for each revolution rotation. That is, the detection by the revolution speed detection unit 72 is used as a trigger signal for conversion (see FIG. 9). The spectrum data shown in FIGS. 5A, 6A, and 7A are obtained by plotting the frequency on the horizontal axis and the amplitude on the vertical axis. As shown in the figure, since a peak appears on the graph of the spectrum data, it is possible to grasp a frequency having a large amplitude or a frequency at which resonance occurs using this graph. The phase component data shown in FIGS. 5B, 6B, and 7B is obtained by plotting the frequency on the horizontal axis and the phase on the vertical axis.

The misalignment determination unit 82 is a portion that revolves together with the rotor 31 and the rotor 31 (the workpiece holding unit 5) based on the detection results of the X-axis acceleration detection unit 711, the Y-axis acceleration detection unit 712, and the Z-axis acceleration detection unit 713. , A balance mechanism 6, etc., and a horizontal plane direction (more specifically, the X axis) of the center of gravity balance position in the revolution rotator R that is a part that revolves in the agitation / defoaming device 1 with respect to the revolution axis C 1. Direction) is determined. Specifically, the center-of-gravity balance position between the container 53 (including the object to be processed) and the balance weight 61 is determined. In the present embodiment, it is determined whether the center-of-gravity balance position is on the container 53 side or the balance weight 61 side on the basis of the revolution axis C1.

The position deviation determination unit 82 stores a collation table 821 in which the relationship between the revolution speed and the phase component is recorded corresponding to each axial direction. This collation table 821 is shown as a collation model which is a curve having a different shape on each axis as shown in FIG. FIG. 10 shows only the weight side collation model. As illustrated in the X axis in FIG. 11, in actuality, in each axis, the curve related to the weight side verification model is related to the container side verification model that is shifted by 180 ° with respect to the curve related to the weight side verification model. There is a curve. By using the collation table 821 in this way, the position shift determination in the position shift determination unit 82 can be facilitated.

The misalignment determination unit 82 includes data of revolution speed (revolution speed) detected by the revolution speed detection unit 72 and data converted by the data conversion unit 81 when each axial acceleration is detected. The phase component data corresponding to the axial direction is input, and the input data is applied to the verification table 821 (verification) to determine misalignment. A specific procedure for determination will be described later.

The vibration determination unit 83 stores a vibration determination table 831. The vibration determination unit 83 compares a value obtained by filtering the spectrum in the spectrum data converted by the data conversion unit 81 with the revolution speed, with a preset threshold value in the vibration determination table 831. This will be described later.

The information display unit 9 can notify the operator of the agitation / defoaming device 1 by displaying various information. As shown in FIG. 3C, the information display unit 9 includes a plurality of first display units 91. 2 display parts 92 ... 92. In the present embodiment, the determination result of the displacement is that a part of the first display unit 91 is lit, and one second display unit 92 indicates whether the center-of-gravity balance position is closer to the container or closer to the weight. indicate. In this manner, the information display unit 9 can notify the operator of the correction direction of the center-of-gravity balance position by performing display corresponding to the determination result of the positional deviation. Specifically, it is possible to notify the operator whether the balance weight 61 should be moved in a direction in which the balance weight 61 is moved closer to the revolution axis C1 or in a direction in which the balance weight 61 is moved away. For this reason, the operator can easily correct the gravity center balance position.

Here, in the conventional agitation / defoaming device, for example, to-be-processed object measurement / injection into container → set container into device → weight balance (center of gravity balance) setting → device operation setting → device stops unbalanced (due to error occurrence) The center-of-gravity balance position was adjusted in the order of (stop)-> weight balance review (re-setting)-> retry (re-set the device operation setting).

For example, in an agitation / defoaming device that adjusts the balance of the weights by stacking a plurality of weights at a fixed position with respect to the revolution axis C1, the operator can Since there was no information to determine whether to increase or decrease the weight, it was decided to “increase” or “decrease” in the prediction (intuition) for each operator and reset the weight balance (center of gravity balance). I was driving again.

In this case, if an error occurs due to the balance of the center of gravity being unbalanced during the operation of the stirring / defoaming device, and the stirring / defoaming device automatically stops, the object to be treated will remain in the air during the stoppage. The material condition changes before the agitation process, such as when the object to be treated absorbs water vapor in the air and the quality changes due to exposure to time (influence of humidity) or the object to be cured begins to cure. There are things to do. In this case, if the workpiece whose material condition has changed is restarted as it is, the workpiece after stirring may not reach an acceptable quality level. For this reason, generation | occurrence | production of material loss and time loss was forced. Particularly when two or more liquids to be processed are mixed, stirring of an adhesive or a curing agent, and stirring of an epoxy resin are greatly affected by the change in the material condition, which is a problem.

Regarding the above problem, the configuration of the present embodiment allows the operator to easily correct the center-of-gravity balance position, so that the material loss and time loss can be effectively suppressed.

The stirring and defoaming apparatus 1 of the present embodiment configured as described above is configured to mount the container 53 in a state in which the object to be processed is stored and the lid body 532 is closed on the container support portion 52 located in the rotor 31, When the container 53 is revolved by rotating the rotor 31 about the revolution axis C1, the centrifugal force due to this revolution acts on the object to be treated, and the object to be treated is pressed against the inner side surface of the container 53 (main body 531). it can. Since the object to be processed is pressed in this way, defoaming can be performed by moving the bubbles present in the object to be processed and taking them out of the object to be processed. Further, when the container 53 is revolved and the powder brake 473 of the speed reduction mechanism 47 is operated to rotate around the rotation axis C2, both the centrifugal force due to the revolution and the centrifugal force due to the rotation act on the workpiece. Thereby, a to-be-processed object can be stirred by rotation, pressing against the side inner surface of the container 53 by revolution. For this reason, a to-be-processed object can be stirred and deaerated.

Then, the agitation / defoaming device 1 of the present embodiment performs displacement determination in the horizontal plane direction (specifically, the radial direction (X-axis direction) with reference to the revolution axis C1), and notifies the operator of the determination result. Thus, it is possible to prompt the operator to adjust the center-of-gravity balance position so as to coincide with the revolution axis C1. By adjusting the center-of-gravity balance position, the vibration accompanying the revolution can be suppressed, and the revolution can be made smooth.

The present invention uses a horizontal plane direction acceleration component that is generally regarded as “noise” in the acceleration data detected by the Z-axis acceleration detection unit 713, and uses the horizontal plane direction component (more specifically, the X-axis direction). The point is to perform misregistration determination. Until now, the component has been eliminated or ignored by noise processing. However, the present inventor has found a correlation in acceleration data in the X, Y, and Z3 axis directions, thereby improving determination accuracy and reliability. I was able to improve the nature. In particular, by using the acceleration data detected by the Z-axis acceleration detection unit 713 that is in the vertical direction, the accuracy of the positional deviation determination in a region where the revolution speed (the number of revolutions) is large can be improved. For this reason, the determination accuracy can be significantly improved as compared with the case where a plurality of X-axis acceleration detection units 711 or Y-axis acceleration detection units 712 are arranged to detect a plurality of acceleration data in the coaxial direction.

FIG. 8 is a block diagram conceptually showing the contents of data processing in the data processing unit 8, and FIG. 9 is a flowchart showing an outline of the data processing. Note that the flowchart of FIG. 9 is simplified and modified based on the actual flow of the present embodiment for easy understanding. Hereinafter, the contents of the data processing in the data processing unit 8 will be described along the flow.

After the main power supply of the agitation / defoaming apparatus 1 is turned on, accelerations in the X, Y, and Z3 directions are detected (step S1). The detection result is accumulated in a memory (not shown) of the data processing unit 8 (step S2).

Next, the presence / absence of a trigger signal corresponding to the detection by the revolution speed detection unit 72 is determined (step S3). When there is a trigger signal, the data conversion unit 81 performs Fourier transform on the acceleration detection result stored in the memory (step S4). If there is no trigger signal, the process returns to step S1.

Next, the filter unit 84 obtains a phase (phase) at a frequency corresponding to the revolution speed detected by the revolution speed detection unit 72 (the phase of the part circled in FIGS. 5B, 6B, and 7B). . A point extracted based on the obtained phase and revolution speed is a phase determination point (see FIG. 11) (step S5).

Next, misalignment determination is performed (step S6). This positional deviation determination is performed by performing “scoring” illustrated in FIG. 11 for each of the X, Y, and Z3 axis directions. For example, the phase determination point A indicated by a circle overlapping with the curve related to the container side matching model is evaluated as +10 points. The phase determination point B indicated by a square overlapping the curve relating to the weight side collation model is evaluated as -10 points. Then, the phase determination point C indicated by x located in the region between the curve related to the container side verification model and the curve related to the weight side verification model is denoted by the reference model of the near side (in this example, the weight side verification model). “−” Is attached on the basis of the curve relating to the model), and the numerical value is assigned as -4 points by attaching the numerical value with a 10-step evaluation with respect to the distance to the matching model on the near side.

The position deviation determination is made by adding the points calculated in the X, Y, and Z3 axis directions as described above, and determining whether the total value is positive or negative.

If one of the three numerical values related to the evaluation of each axis is an abnormal numerical value, the result relating to the abnormality is excluded in this misalignment determination step, and the remaining two numerical values are excluded. And the direction of positional deviation is determined based on the sign of the sum of the two numerical values. That is, when the determination is made based on the detection results of the X-axis acceleration detection unit 711, the Y-axis acceleration detection unit 712, and the Z-axis acceleration detection unit 713, the detection result related to the abnormal numerical value is not used. In this case, for example, the determination is based on only two detection results of the X-axis acceleration detection unit and the Y-axis acceleration detection unit. For this reason, since it can suppress that it becomes impossible to determine by the influence of the said abnormal numerical value, balance detection can be improved.

Next, a value obtained by filtering the spectrum in the spectrum data by the revolution speed (that is, a value at a frequency corresponding to the revolution speed) is set in advance and the threshold value in the vibration determination table 831 stored in the data processing unit 8 is used. It is determined whether or not the comparison is larger (step S7). If the filtered value is larger than the threshold value, the process proceeds to the next step (step S8). If the filtered value is less than or equal to the threshold value, the process returns to step S1.

Next, the misalignment determination result is displayed on the information display unit 9 (step S8). As described above, when the value obtained by filtering the spectrum in the spectrum data by the revolution speed is larger than a preset threshold value, this display is displayed as a vibration warning (see FIG. 8). For this reason, since it can alert | report to the operator of the stirring and defoaming apparatus 1 only when adjustment of the balance weight 61 is required, complication of alerting | reporting can be suppressed. That is, it is possible to reduce annoyance to the operator.

Next, when the main power source of the stirring / defoaming apparatus 1 is cut off, the process is terminated. Otherwise, the process returns to step S1 (step S9).

Although one embodiment has been described above, the present invention is not limited to this. For example, in the above-described embodiment, the acceleration detection unit 71 is detected when the revolution speed is constant, but it can also be detected during acceleration / deceleration. However, since the detection value of the acceleration detector 71 is smaller than that in the steady state during acceleration / deceleration, the detection value needs to be corrected.

Further, in the embodiment, the balance weight 61 is configured to be able to move toward and away from the revolution axis C1, but the balance adjustment method is not limited to this. For example, a balance adjustment is performed by stacking a plurality of weights at a fixed position with respect to the revolution axis C1, or two

containers

One or more.

Further, the driving force transmission mechanism 22 is not limited to a transmission system using a belt as in the above-described embodiment. For example, a transmission system using a gear or a chain or a transmission system in which the driving shaft 211 of the motor 21 is directly connected to the rotary shaft 23. The transmission format may be changed as appropriate.

In the above-described embodiment, the speed reduction mechanism 47 includes the powder brake 473. However, a mechanism including a motor can be used instead of the powder brake 473 as a mechanism capable of increasing and decreasing the speed. The motor in this mechanism is accelerated by energization and decelerated by the regenerative operation (acting the motor as a brake).

It is also possible to provide a mechanism for automatically adjusting the position of the balance weight 61 by driving a motor or the like according to the determination result of the positional deviation.
