Description

parts supply device

The present invention relates to a component supply device for vibrating conveying components, and in particular, to a component supply device that further reduces the number of wires that need to be pulled back and improves the convenience of assembly to an applicable object.

As one of the parts supply devices that convey parts by vibration, a parts feeder shown in Patent Document 1 (Japanese Patent No. 6016101) is known. Such a feeder generally includes a hopper feeder and a linear feeder as a vibrating machine for arranging and selecting the inserted parts, and a return feeder for returning the parts removed by the linear feeder to the hopper feeder.

Each vibrator includes a conveyor including a running surface of the components and a vibration drive unit that vibrates the conveyor. The vibrators cooperate with each other to smoothly transfer the components, and are appropriately positioned on the base. Components are assembled in the state.

In addition, in order to drive these, a controller outside the module is connected to the drive unit through wiring. The controller integrally constitutes a driver for inputting a drive signal to the vibrating drive unit and an input device for inputting settings of how to vibrate the drive unit. Based on the content input to the input device, the driver inputs a drive signal and a conveyance path to the vibrating drive unit. Make vibration.

For example, the frequency and amplitude when vibrating the conveyance path are input from the input device. When the driver includes a conversion circuit, a corresponding drive signal is input from the driver to the drive unit based on the frequency and amplitude input from the input device. way of composition. As vibration principles, generally known methods include a method of conveying parts by elliptical vibration and a method of conveying workpieces by traveling waves.

However, when such a component supply device is installed on the supply target equipment, the components that convert the vibration machine into an assembly must be installed at an appropriate position of the supply target equipment, and the controller connected to the assembly must also be placed at an appropriate position around it. Details are described below.

The parts feeder can change the supply capacity of parts according to the amplitude, frequency and vibration conditions of the driving surface. In fact, in addition to vibration conditions, the vibration conditions change due to various factors such as deviations in shape and surface coating status due to workpiece batches, generation of static electricity, surrounding environment (humidity, temperature), dirt on the driving surface, etc. Supply capacity is not necessarily one-to-one. It is common practice to use a controller to adjust the amplitude and frequency at any time under the above-mentioned environment and batch conditions so that the capacity at the exit of the conveyance unit is the desired capacity. Particularly in a vibrator that is an assembly composed of a plurality of drive units, the capacity of the conveyor unit outlet cannot be adjusted unless the conditions of the plurality of drive units are adjusted. Therefore, in an environment where the operator monitors the transportation status of the vibrator, the supply capacity can be adjusted, and the controller is placed in a position that is easy for the operator to use.

In this case, the controller is connected to each vibrator through wiring. In addition, the types of wiring include power lines, control signal lines, and communication lines. In addition, since wiring is also included in the supply target equipment, the entire system requires A large amount of wiring is pulled back and must be processed on the supply target device. Therefore, when the equipment needs to be constructed within a restricted range, there are difficulties in wiring paths, wiring duct space, and piping time, and problems of coordination of the installation space of the controller in the supply target equipment will inevitably arise.

In addition, when supply target equipment such as visual inspection equipment and taping machines include movable parts, it is difficult to install a controller around the vibrator due to the installation space in the supply target equipment, so there must be a wiring margin. , if the wiring is inadvertently pulled back, the possibility of disconnection due to contact with the movable part increases.

Furthermore, if the driver in the controller is used to switch the converter circuit on/off, electromagnetic waves are radiated in the middle of the wiring. Therefore, there is a possibility of malfunction of the device and a decrease in response time due to radiated interference to the supply equipment. sex.

Furthermore, when components are transported in a packaged state for assembly on site, the amount and types of wiring to be packaged increase. As a result, there are more wiring connection locations, and more labor and time are required for assembly.

The present invention focuses on such a subject, and aims to provide a component supply device related to vibrating conveyance components. In particular, the present invention provides a component supply device that reduces the number of wires that need to be pulled back and improves the convenience of assembly to an application object.

In order to achieve this object, this invention adopts the following means.

That is, the parts supply device of the present invention is characterized in that one or more vibrators including a conveyance part for conveying parts and a vibrating drive part for vibrating the conveyance part are mounted on the base as an assembly, and on the above-mentioned assembly A drive unit control device that inputs a drive signal to the vibration drive unit is integrally assembled in one part, and wiring is performed between the vibration drive unit and the drive unit control device in the assembly.

In this way, the wiring between the vibration drive unit and the drive unit control device is pulled back within the assembly, and the wiring is shortened. Therefore, compared with the conventional wiring that protrudes out of the module, the number of wirings is reduced. When the component supply device is installed on the supply target equipment, it will not be difficult to retrieve the wiring, and the installation can be performed with fewer work steps. Risks can also be reduced. In addition, since the accompanying electromagnetic waves can be suppressed from being radiated outside the module, the impact of noise on the surroundings can be reduced.

Moreover, the above-mentioned drive unit control device does not include a display unit and an operation unit, and it only needs to receive setting information from outside the component and input a drive signal to the above-mentioned vibration type drive unit. There is no need to consider arranging the display unit and operating unit at positions with good visibility and operability for the operator, thereby increasing the freedom of arrangement. Therefore, the dead space can be utilized and the drive unit control device can be arranged at an appropriate position.

In this case, the drive unit control device includes a power supply unit that supplies power to the vibration drive unit, a drive unit that drives the power supply unit, and a control unit that controls the power supplied to the vibration drive unit by the drive unit. The configuration of the setting information receiving portion that receives setting information input to the control portion makes it easy to emit electromagnetic waves because the driving signal accompanying the switching operation flows from the power supply portion to the vibrating driving portion. However, in the present invention, these are It is stored in the module and wired inside the module to make the noise countermeasures more effective.

In addition, if it is an input device that is configured independently from the above-mentioned components and includes an operation part and a display part that can communicate with the above-mentioned drive part control device, the drive part control device is disposed close to the vibration drive part, and the input device can be appropriately used. A solution that is placed in a location that is easy for the operator to operate.

In this case, if the drive unit control device and the input device are connected by a serial line including at least a communication line, the number and thickness of the serial lines can be reduced, thereby improving the convenience of pulling back, and also can Eliminates the possibility of electromagnetic wave radiation.

Furthermore, even if a plurality of vibration-type drive units are connected to a common drive unit control device, and the driving unit of each vibration-type drive unit is shared as a drive unit control device, it is possible to control the power supply circuit by the CPU and the power supply circuit in the drive unit control device. , miniaturization resulting from the common use of the casing. Furthermore, in a structure that does not include the functions of an operating unit and a display unit, there is no need to consider operator operability. That is, further miniaturization can be achieved by not including the functions of the operation unit and the display unit in the drive unit control device.

The effects of the present invention are as follows.

Since the present invention has the structure described above, it is possible to provide a component supply device for vibrating conveying components. In particular, it is possible to provide an excellent component supply device that reduces the number of wires that need to be pulled back and improves the convenience of assembly to an applicable object.

The return feeder 4 returns the unsuitable workpieces from the linear feeder 3 to the hopper feeder 2. Hopper 5 where workpieces are put into the hopper. Each of the feeders 2, 3, and 4 is arranged on the base 10, and is assembled into modules in a suitably positioned state so that they cooperate with each other and can be smoothly handed over. In particular, since the precision parts described above are extremely small, a parts supplier for this application densely arranges the vibrators 2 to 4 on a base 10 with a width of approximately a quadrangular shape of several tens of centimeters. Hereinafter, each of the feeders 2, 3, 4 and the bin 5 will be described as a hopper B, a straight line L, a return R, and a bin H as necessary.

FIG. 2 schematically shows such a component supply device 1 together with the supply target equipment TE to which it is applied. This supply target equipment TE inspects and processes supplied workpieces such as a visual inspection device and a taping machine. Therefore, like general factory equipment, the installation space is limited from the viewpoint of space factors and productivity improvement. For example, the supply target equipment TE is a cube with a width of 1 meter to several meters. A space is secured in one corner, the parts supply device 1 is installed there, and the supply port 1x is connected to the supply target equipment TE. This requires cooperation in control. .

By driving the vibrating drive unit 22, the hopper 21 is vibrated, and the workpieces are sequentially conveyed in the circumferential direction.

The linear feeder 3 is connected to the hopper feeder 2 via a connecting member 23 .

The linear feeder 3 includes a groove 31 as a conveying portion extending linearly in the conveying direction, and a vibrating drive portion 32 located below the groove 31 (only a part of the leaf spring as a component is shown in the figure).

A conveyance groove 311 extending in the horizontal direction is formed in the upper part of the groove 31 along the longitudinal direction. The transport groove 311 also has a V-shaped cross section perpendicular to the transport direction, and a rectangular parallelepiped workpiece such as an IC chip is transported with both surfaces in contact with both surfaces of the V-shaped groove.

The connection member 23 is also provided with a conveyance groove having a V-shaped cross section, and the groove 311 of the linear feeder and the groove 213 of the hopper feeder 2 are connected through the conveyance groove of the connection member 23 .

The vibrating driving part 32 includes an electromagnet and a leaf spring supporting the groove 31. Vibration is transmitted from the vibrating driving part 32 to the groove 31 by excitation of the electromagnet, and the groove 31 vibrates reciprocally. By driving the vibrating drive unit 32 to vibrate the groove 31, the workpiece transferred from the connecting member 23 is sequentially transferred to the downstream side in the transfer direction.

The linear feeder 3 is provided with a determination unit 33 including a camera that determines the posture of the workpiece, and a workpiece removal unit 34 for removing workpieces with incorrect postures using air.

The return feeder 4 includes a groove 41 as a conveyance portion extending in parallel with the groove 31 of the linear feeder 3 , and a vibrating drive portion 42 located below the groove 41 . The conveying direction is the same as the linear feeder Opposite Direction. The return feeder 4 may be configured to be driven by the vibration of the vibration drive unit 32 of the linear feeder 3 instead of the vibration drive unit 42 .

A conveyance groove 411 extending in the horizontal direction is also formed in the upper part of the groove 41 along the longitudinal direction. The transport groove 411 also has a V-shaped cross section perpendicular to the transport direction, and a rectangular parallelepiped workpiece such as an IC chip is transported with both surfaces in contact with both surfaces of the V-shaped groove.

Then, the workpieces removed by the workpiece removal section 34 on the linear feeder 3 are returned to the hopper 21 through the return feeder 4 .

Furthermore, since the hopper 5 is configured to supply the workpieces put into the hopper 21 from the nozzle portion on the lower end side along the inner surface of the funnel shape, the portion from the inner surface of the funnel shape to the nozzle portion becomes the conveyance path 51 . The magazine 5 is also configured to smoothly convey the workpiece to the nozzle unit side by being driven by the vibration drive unit 52 .

In the present embodiment, the vibrators 2, 3, 4, and 5 are represented as hopper B, straight line L, return R, and bin H, and the vibration drive units 22, 32, 42, and 52 are also represented as A(B). ,A(L),A(R),A(H). FIG. 3 is a block diagram showing a control system and an input system for each vibration drive unit A (L, B, R, H). This component workpiece device 1 includes a drive unit control device 6 that supplies power to a vibration drive unit A (L, B, R, H), and a device for the operator to set the frequency and amplitude related to the drive unit control device 6. Input device 7.

The vibration drive part A (L, B, R, H) and the drive part control device 6 are integrated as a module U on the base 10, and the input device 7 can be arranged in a structure that is different from the module U. The location, such as the operator's hand, is connected through the communication mechanism 8 .

FIG. 6 shows the conventional controllers C1 to C4, which will be described later. However, in this embodiment, the conventional controllers C1 to C4 are separated into the drive unit control device 6 and the input device 7 as shown in FIGS. 3 and 4(a). , disposing the drive unit control device 6 on the module U side is equivalent to a structure in which the input device 7 is separated by the communication mechanism 8 .

The drive unit control device 6 shown in FIG. 3 includes a drive circuit 61 as the AC output of the power supply unit of the present invention, a bridge driver 62 as a drive unit that drives the drive circuit 61, a control unit 63, and a serial communication circuit 64. , Amplitude sensor feedback circuit 65.

The drive circuit 61 is a circuit that inputs a drive signal Sv to the vibration drive part A (L, B, R, H), and includes a circuit that controls the current flowing through the drive part A (L, B, R, H) (in the case of a piezoelectric element) is the voltage) H-bridge circuit. The bridge driver 62 is a circuit that drives this H-bridge circuit. The H-bridge circuit and the bridge driver 62 correspond to what is generally called a switching section of a converter.

The control unit 63 controls the amplitude, frequency, etc. of the electric power supplied to the vibration drive unit A (L, B, R, H) via the bridge driver 62 . The control unit 63 is composed of, for example, a digital computing processing circuit including a memory that stores a predetermined program and a CPU that reads and executes the predetermined program. When the setting information D1 is input, the bridge driver 62 is controlled accordingly.

The serial communication circuit 64 is connected to the serial communication circuit 73 of the input device 7 via the wiring 8 as a communication mechanism, communicates between the serial communication circuits 73 and 64, and inputs the setting information D1 from the operator to the control unit 63. This serial communication circuit 64 corresponds to the setting information receiving unit of the present invention.

In addition, it is not limited to the information receiving unit, but may also be used as a display to obtain the output of the driving unit from the driving unit to the driving unit control device 6 through communication, the feedback value of the vibration sensor, the presence or absence of the operation signal input from the outside, caution, warning display, etc. The surveillance department functions.

The amplitude sensor feedback circuit 65 acquires the amplitude by inputting detection values of the amplitude sensors provided in the vibrators 2 to 5, feeds back the amplitude to the control unit 63, and performs feedback control so that the amplitude becomes the set input amplitude.

Furthermore, as shown in FIG. 4(a) , the drive circuit 61 , the bridge driver 62 , the control unit 63 , the serial communication circuit 64 , and the amplitude sensor feedback circuit 65 are housed in one chassis, and are assembled as the drive unit control device 6 As shown in FIG. 1 , the drive unit control device 6 is installed on the base 10 together with the vibration drive unit A (L, B, R, H) (22, 32, 42).

Between the drive unit control device 6 and the vibration drive unit A (L, B, R, H), specifically between the vibration drive unit A (L, B, R, H) and the drive circuit 61 and the vibration drive Part A (L, B, R, H) and the amplitude sensor feedback circuit 65 are connected in the module U through extremely short wirings Ca and Cb. Here, the group of these wirings Ca and Cb is regarded as one internal wiring Cy.

On the other hand, in this embodiment, a multi-core cable Cx is used in the wiring 8 as a communication mechanism that connects the input device 7 and the drive unit control device 6 shown in FIG. 4(a) . As shown in FIG. 4(b) , at least one of the multi-core cables Cx is used as the energy line Pw to supply electric power of a predetermined voltage from the drive unit control device 6 to the input device 7, and at least the number of vibrators (here, 4 (root) is used as a serial communication line S for transmitting the setting information D1 related to each vibration drive unit A (L, B, R, H). In addition to LAN cables, multi-core cable Cx can also use electric wires, etc. In contrast to the meaning that the internal wiring Cy is housed in the module U, the wiring 8 can be called external wiring in the sense that it is pulled out to the outside of the module U and pulled back.

Of course, the energy line Pw is a device that can be used simply by connecting the input device 7 to the drive unit control device 6, and other power sources may be used on the input device 7 side. At the same time, the connection between the input device 7 and the drive unit control device 6 can also be made wireless.

The drive unit control device 6 is provided with a hopper feeder connection port P(B), a linear feeder connection port P(L), a return feeder connection port P(R), and a bin connection port P(H). Each port P It is connected to each vibration drive part A (L, B, R, H) in the unit U by an internal wiring Cy. As shown in FIG. 4(c) , each internal wiring Cy includes a power line Ca to which an AC output of the drive signal Sv of the drive circuit 61 is input, and a feedback line F to feed back the detection value of the amplitude sensor.

The input device 7 shown in FIG. 3 includes a setting input display unit 71, a signal processing unit 72, and a serial communication circuit 73. The setting input display unit 71 is a touch panel type device, and therefore receives setting input regarding the frequency and amplitude of the power supplied to the vibration drive unit A (L, B, R, H) from the operator, and displays the current settings. condition. The signal processing unit 72 recognizes the setting information input to the setting input display unit 71 The setting information D1 is provided to the control unit 63 of the drive unit control device 6 through the serial communication circuits 73 and 64. In addition, the signal processing unit 72 stores the current setting information D1 and displays it on the setting input display unit 71 . These setting input display unit 71, signal processing unit 72, and serial communication circuit 73 are housed in a single chassis.

FIG. 5 shows the structure of the display unit and input unit of the setting input display unit. The setting input display unit 71 includes selection units 71a1 to 71d1 for selecting one of the hopper B, the straight line L, the return R, and the bin H, first setting units 71a2 to 71d2 for each setting amplitude and voltage value, and The second setting parts 71a3 to 71d3 each set the frequency. Amplitude and voltage are mainly used to adjust the conveying speed of the workpiece. The frequency is set according to the amplitude in a manner to effectively transmit the conveying force to the workpiece, or is automatically adjusted according to the frequency and amplitude. The components indicated by 71a4 to 71d4 in the figure are the third setting part of soft start for slowly starting.

The speed of the workpiece is determined by these settings and the friction between the workpiece and the conveyor path. In addition to the adjustment of the supply speed, the speed of the workpiece is also related to the adjustment of the distance between the workpieces. Adjustments are made in a timely manner by the operator while observing the actual operating conditions. The arrow

Furthermore, the supply port 1x of the component supply device 1 is connected to the supply target equipment TE, and in order to realize control cooperation, the operation command unit OC (see FIG. 3 ) of the supply target equipment TE is sent to the control unit 63 of the component supply device 1. The start/stop signal is input and synchronized.

6 and 7 show a conventional component supply device 101 as a comparative example. In the element parts corresponding to Figure 3, mark the last two equal hundreds symbols except for some parts. In this component supply device 101, controllers C1 to C4 are respectively connected to each vibration drive section A (L, B, R, H), and each controller C1 to C4 integrates a drive circuit 161, a bridge driver 162, and a control section. 163. Set the input display unit 171 and the signal processing unit 172. Furthermore, when the component supply device 101 is installed in the supply target equipment TE in FIG. 2, the control The controllers C1 to C4 are arranged at a certain position of the supply target equipment TE, and it is necessary to connect the components supply device 101 and the controllers C1 to C4 through external wiring 108 .

Therefore, only the number of controllers C1~C4 is used to obtain the space. Therefore, as shown in FIGS. 8 and 9 , it is considered as an effective method to reduce the volume increase by integrating the functions of the controllers C1 to C4 into one controller Cc.

However, when the controllers C1 to C4 are arranged at a certain position, the frequency of vibration and frequency readjustment is high from the perspective of the input device. If we take into account the readjustment caused by changes in the type, batch, surrounding environment, and static electricity, In order to eliminate such slight maintenance interruptions such as adjustment, cleaning of the conveyance path, and workpiece clogging, the controller Cc is preferably installed at a position that is easy for the operator to operate. As shown in Figure 2, the arrow On other free spaces on the base 10 of the feeder 3 and the hopper feeder 2. However, for the above reasons, it is desirable to place the input device as close to the operator as possible.

On the contrary, from the viewpoint of the drive unit control device 6, it is desirable to arrange each of the vibrating drive units 22, 32, 42, 22, 32, 42, etc., which are drive sources close to the drive hopper B, the straight line L, the return R, the bin H, etc. on the base 10. 52 position.

These are opposite propositions, and it is common that the space for installing the controller Cc is not sufficiently sufficient for the parts supplier initially assembled in an appearance inspection device or the like. What's more, the unmerged controllers C1~C4 are even more obvious. Furthermore, the number of external wirings 108 connecting the controllers Cc, C1 to C4 and the vibration drive parts A (L, B, R, H) is still large.

As mentioned above, the presence of the external wiring 108 is not only inconvenient for wiring processing and device assembly, but is also undesirable from various viewpoints such as the influence of radiation interference.

Therefore, as shown in FIGS. 3 and 4(a) , the present embodiment is configured by dividing the functions of the integrated controller Cc into the drive unit control device 6 and the input device 7. As shown in FIG. 1, the drive unit The driving part control device 6 is arranged in a blind spot on the base 10, that is, on the back side that is difficult to reach and difficult to handle from the operator's observation hand. The driving part control device 6 is connected to each other on the base 10 through internal wiring Cy. Connect the wiring between the vibration drive parts A (B, L, R, H) (22, 32, 42, 52) of the vibrators 1 to 4.

On the other hand, the input device 7 is pulled out from the unit U via the wiring (external wiring) 8 as a communication mechanism, and the operator can operate it at hand. This wiring 8 is extremely small in number compared with the wiring 108 of the conventional device shown in FIG. 6 and has a sufficiently soft and thin wire shape. In addition, it does not flow through and generate strong electromagnetic waves such as the on/off signal of the converter. drive signal.

The component supply device 1 of the present embodiment configured in this way has an air mechanism for removing the workpiece built-in in the package in addition to the component U, the input device 7 and the external wiring 8 even if the package is transported to the position where the supply target equipment TE is set. , the number of assembly points and the number of wirings is also small, so the wiring connection positions after removal are minimized, and the assembly work can be performed extremely easily.

The input device 7 includes a plurality of operating parts such as encoders operated by the operator (eg, , if we talk about the straight line L, the setting parts 71a2, 71a3, 71a4, etc.) have the function of adjusting multiple parameters simultaneously. Therefore, unlike the input device disposed in the supply target equipment TE, the input device 7 can be used as a controller dedicated to controlling the parts feeder of the parts supply device 1 that is the control object.

As described above, the parts supply device 1 of this embodiment assembles the conveyance parts 21, 31, 41 and the conveyance path 51 including the conveyance parts as an assembly on the base 10, so that these conveyance parts 21, 31, 41 and the conveyance path The components supply device 1 for the vibrating machines 2, 3, 4, and 5 of the vibrating drive unit A (L, B, R, H) (22, 32, 42, 52) of the 51-vibrating unit is integrated with a part of the assembly U The drive unit control device 6 for inputting the drive signal Sv to the vibration drive unit A (L, B, R, H) is assembled in a precise manner, and the vibration drive unit A (L, B, R, H) and the drive unit are connected in the assembly U. A device for wiring between control devices 6.

In this way, the retraction of the internal wiring Cy between the vibration drive part A (L, B, R, H) and the drive part control device 6 is completed in the unit U, and the internal wiring Cy is also shortened. Therefore, proceed with the existing In comparison, there are fewer wirings protruding out of the module U and there is almost no wiring margin. When the component supply device 1 is installed in the supply target equipment TE, the wiring processing is not difficult and can be performed with fewer work steps. Assembly can also reduce the risk of wire breakage. In addition, since the emission of electromagnetic waves outside the module U can be suppressed, the influence on surrounding noise can also be reduced.

In addition, the drive unit control device 6 does not include a display unit and an operation unit, but is configured to receive setting information D1 from outside the component and input a drive signal Sv to the vibration drive unit A (L, B, R, H).

In this way, since the display unit and the operation unit are not provided, there is no need to arrange the drive unit control device 6 at a position that is easy to see and operate for the operator, thereby increasing the freedom of arrangement. Therefore, as in this embodiment, the dead space can be utilized and the drive unit control device 6 can be arranged at an appropriate position.

Specifically, the drive unit control device 6 includes a drive circuit 61 as a power supply unit that supplies power to the vibration drive unit, a bridge driver 62 as a drive unit that drives the drive circuit 61, and a bridge driver 62 as a drive unit. 62 is a control unit 63 that controls power to the vibration drive unit A (L, B, R, H), and a serial communication circuit 64 that is a setting information receiving unit that receives setting information input to the control unit 63.

That is, since the drive signal Sv accompanying the switching operation flows from the drive circuit 61 as the power supply unit to the vibration drive unit A (L, B, R, H), electromagnetic waves are easily emitted. However, in this embodiment, since these parts It is housed in the unit U and wired through the internal wiring Cy in the unit U, so the noise countermeasures are more effective.

Furthermore, this embodiment also includes an input device 7 that is configured independently from the unit U and includes a setting input display unit 71 as an operation unit and a display unit that can communicate with the drive unit control device 6 . In this way, the drive unit control device 6 is arranged close to the vibration drive unit A (L, B, R, H), and the input device 7 is suitably arranged at a position that is easy for the operator to operate.

Furthermore, the drive unit control device 6 and the input device 7 are connected by a serial line 8 including at least a communication line. Under such a structure, since the number and thickness of the serial lines 8 can be reduced, the convenience of wiring processing can be improved, and the risk of electromagnetic wave radiation can also be eliminated.

Furthermore, in this embodiment, a plurality of vibration-type drive units 22, 32, 42, and 52 are connected to a common drive unit control device 6. However, even if the drive unit control device 6 shares each of the vibration-type drive units 22, 32, and 42 , 52 can also be driven in a compact manner by sharing the CPU, control power supply circuit, and casing in the drive unit control device 6 . Furthermore, since it does not include the functions of an operating unit and a display unit, operator operability does not need to be considered. That is, by not including the functions of the operation unit and the display unit in the drive unit control device 6, further miniaturization can be achieved.

As mentioned above, one embodiment of the present invention has been described. However, the specific structure of each part is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.

For example, in the above-mentioned embodiment, a touch screen type tablet computer is used as the input device 7, but it may also be a higher-level controller (PLC and server) or a smartphone. The communication mechanism may also be Blue-tooth, Wifi, optical fiber, etc., and is not particularly limited.

As shown in FIG. 10 , in this case, only the drive unit control device 6 is installed in the parts supply device. As long as communication is possible between the setting information receiving unit 64 of the drive unit control device 6 and an external input device, it is acceptable. It can achieve the functions and effects based on the above embodiment.

Alternatively, in the above-mentioned embodiment, the case where the control unit 63 includes the operation mode has been described. However, the operation mode of which vibration machine is started at which frequency and amplitude may be included in the controller in the form of a table or the like as setting information. D1 is input to the setting information accepting unit 64 .

In this case, as the setting information D1 from the upper controller, an analog signal for controlling the vibrator with a predetermined voltage, a predetermined current, and a predetermined frequency and amplitude is input to the setting information receiving unit 64 of the drive unit control device 6 .

In addition, in the above-mentioned embodiment, the drive unit control device 6 is integrated and modularized. However, as long as it is assembled into the unit U, the drive unit control device 6 may be further disassembled, for example, into the vibration components of the hopper B, the straight line L, and the return R. The electromagnets, counterweights, springs, etc. of the type driving parts 22, 32, and 42 are respectively integrally assembled into the bridge driver 62 and the driving circuit 61. The same applies to the case where a piezoelectric element is used instead of an electromagnet. In addition to the conveyance by elliptical vibration, the conveyance principle may also be conveyance by traveling waves.

In addition, as shown in FIG. 11 , as another arrangement example of the drive unit control device 6 , a base 10 a is placed under the base 10 , and an anti-vibration system such as an anti-vibration rubber or an anti-vibration spring is used between the base 10 and the base 10 a. In the case of 10b connection, a recessed portion 10a1 or the like may be provided on the base 10a side and the drive unit control device 6 may be installed.

Alternatively, as shown by the dotted line in this figure, it is also effective to arrange the drive unit control device 6 between the base 10 and the chassis 10a.

This arrangement is not only effective as a blind space, but also has an electromagnetic shielding effect when the base 10, the base 10a, and the chassis (frame) of the drive unit control device 6 are made of metal. In addition, since the base 10 and the base 10a can be Since it is used as a heat sink, the heat dissipation characteristics can be expected to be improved and the components of the drive control device 6 themselves can be reduced in size.

In addition, since the wiring does not protrude from the module, there is no need to take measures such as shielding the wiring, which is advantageous in terms of cost and convenience in wiring handling.

In addition, in the above-mentioned embodiment, the case where the vibrator includes the hopper B, the straight line L, the return R, and the bin H is explained. However, in some configurations, for example, only the hopper B, the straight line L, and the return R are used. In the case of hopper B, straight line L, or only straight line L, the above-mentioned standard effects can also be achieved. On the contrary, the same situation applies to a vibration system that uses other vibration machines as part or all of it.

In addition, the operation part only needs to have a structure that satisfies the expected functions, and is not limited to an encoder, but may be a keyboard, a button, a variable resistor, a liquid crystal display including a touch screen, a voice control, etc.
