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 ease of assembly to applicable objects.

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

Each vibrating machine includes a conveying part that includes the running surface of the component, and a vibrating drive part that vibrates the conveying part. The vibrating machine cooperates with each other to smoothly transfer the parts, and is properly positioned on the base. Assemble in components in the state.

In addition, in order to drive these, a controller outside the module is connected through wiring in the drive section. The controller integrally constitutes a driver for inputting drive signals to the vibrating drive unit, and an input device for setting and inputting how to vibrate the drive unit. According to the input from the input device, the driver inputs the drive signal and conveying path to the vibrating drive unit. Vibrate.

For example, it is configured to input the frequency and amplitude when the conveying path is vibrated from the input device. When the drive includes a conversion circuit, according to the frequency and amplitude input from the input device, the drive signal is input from the drive to the drive unit. Way of composition. As the principle of vibration, it is generally known that a type of component is conveyed by elliptical vibration, and a type of workpiece is conveyed by traveling waves.

However, when such a component supply device is installed on the supply target device, the component that forms the vibrator into a module is installed in the appropriate position of the supply target device, and the controller connected to the module also needs to be placed in an appropriate location around. The details are described below.

The parts feeder can change the supply capacity of parts according to the amplitude, frequency and vibration conditions of the running surface. Actually, in addition to the vibration conditions, the shape and surface coating state deviation due to the batch of workpieces, the generation of static electricity, the surrounding environment (humidity, temperature), the dirt on the running surface, etc. change due to various factors. Supply capacity may not be one-to-one. As in the manner in which the capacity at the exit of the conveying unit is the desired capacity, in the above-mentioned environment and batch conditions, it is a general rule to use the controller to adjust the amplitude and frequency at any time. In particular, in a vibrating machine that is an assembly formed by assembling a plurality of driving parts, if the conditions of the plurality of driving parts are not adjusted, the capacity of the conveying part outlet cannot be adjusted. Therefore, in an environment where the operator monitors the conveying state of the vibrating machine, the supply capacity can be adjusted, so that the controller is located at a position that is easy for the operator to use.

In this case, the controller and each vibrating machine are respectively connected by wiring. On this basis, the types of wiring also include power lines, control signal lines, and communication lines. Moreover, since the supply target equipment also includes wiring, it is necessary for the system as a whole A large amount of wiring is pulled back, and wiring processing must be performed on the supply target equipment. Therefore, when it is necessary to construct equipment within a restricted range, there are difficulties in wiring routes, wiring duct space, and piping time, and the problem of coordination of the installation space of the controller will inevitably occur in the supply target equipment.

In addition, when the supply target equipment such as the visual inspection device or the taping machine includes a movable part, in relation to the installation space in the supply target equipment, it is difficult to install the controller around the above-mentioned vibration machine, so there must be a wiring margin. If the wiring is pulled back inadvertently, the possibility of disconnection due to contact with the movable part increases.

In addition, if the driver in the controller is used to switch the conversion circuit on/off, electromagnetic waves are radiated in the middle of the wiring. Therefore, there is a possibility that the device may malfunction due to radiation interference to the supply equipment and the response time may be reduced. Sex.

In addition, when components are transported in a packaged state for assembly on site, the amount and types of wiring for packaging increase. As a result, wiring connection positions increase, and more labor and time are required for assembly.

The present invention focuses on such a problem, and an object thereof is to provide a component supply device related to vibration conveying components, in particular, a component supply device that reduces the number of wires that need to be pulled back and improves the ease of assembly to an applicable object.

The present invention adopts the following solutions in order to achieve this object.

That is, the component supply device of the present invention is characterized in that one or two or more vibrating machines including a conveying part for conveying parts and a vibrating drive part that vibrates the conveying part are mounted on the base as a component, and the components are A drive unit control device that inputs a drive signal to the vibratory drive unit is partially assembled integrally, and a connection is made between the vibratory drive unit and the drive unit control device in the assembly.

In this way, the wiring between the vibrating drive unit and the drive unit control device is pulled back in the assembly, and the wiring is also shortened. Therefore, the number of wires protruding out of the module will be reduced compared with the existing ones. When the component supply device is installed on the supply target equipment, it will not be difficult to retrieve the wires, and the installation will be carried out with less work steps, and the wires will be disconnected. The risk can also be reduced. In addition, since the accompanying electromagnetic waves can also be suppressed from being emitted to the outside of the module, the influence of noise on the surroundings can be reduced.

Moreover, the drive unit control device does not include a display unit and an operating unit, as long as it receives setting information from outside the package and inputs a drive signal to the vibrating drive unit, it does not need to be considered when there is no display unit or operating unit. Arrange the drive unit control device at a position with good visibility and operability for the operator to increase the degree of freedom of arrangement. Therefore, the blind space can be utilized, and the drive unit control device can be arranged at an appropriate position.

In this case, if the drive unit control device includes a power supply unit that supplies power to the vibratory drive unit, a drive unit that drives the power supply unit, and control of the power to the vibratory drive unit through the drive unit. The configuration of the setting information receiving section that receives the setting information input to the control section is configured to easily emit electromagnetic waves because the drive signal accompanying the switching operation flows from the power supply section to the vibrating drive section. However, in the present invention, these Stored in the module and wired in the module, noise countermeasures are more effective.

In addition, if it is an input device that is configured independently of the above-mentioned components and includes an operation unit and a display unit that can communicate with the drive unit control device, the drive unit control device is arranged close to the vibrating drive unit, and the input device can be suitably used The solution is placed in a location where the operator can easily operate.

In this case, if the drive unit control device and the input device are connected through 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 pull-back. Eliminate the possibility of electromagnetic wave radiation.

In addition, by connecting multiple vibrating drive units to a common drive unit control device, even if the drive unit is used as a drive unit control device to share the drive structure of each vibrating drive unit, the CPU and control power circuit in the drive unit can be controlled by the drive unit. , Miniaturization due to common housing. Furthermore, in a structure that does not include the functions of the operation unit and the display unit, there is no need to consider the operability of the operator. That is, it is possible to realize further downsizing due to the fact that the function of the operation unit and the display unit is not included in the drive unit control device.

The effects of the present invention are as follows.

Due to the structure described above, the present invention can provide a component supply device for vibrating conveying components, and in particular, provides an excellent component supply device that reduces the number of wires that need to be pulled back and improves the ease of assembly to the applicable object.

Fig. 2 schematically shows such a component supply device 1 together with a supply target equipment TE as an application object. Since the supply target equipment TE inspects and processes the supplied workpieces such as an appearance inspection device, a braiding machine, etc., it is the same as general factory equipment and the like, and the installation space is limited from the viewpoint of space factor and productivity improvement. For example, the supply target equipment TE is a cube with a width of 1 meter to several meters wide, and space is secured at one of the corners, and the parts supply device 1 is installed there. The supply port 1x is connected to the supply target equipment TE, which requires control cooperation . This embodiment is a way to improve its assemblability.

Returning to Fig. 1, the hopper feeder 2 includes a hopper 21 capable of accommodating a conveyance part of a workpiece supplied from a hopper 5 as a component input mechanism indicated by a phantom line in the figure, and a vibrating drive part 22 located below the hopper 21 (in The method is not shown in the figure). The hopper 21 includes a bottom portion 211 bulged in the center that is circular in plan view, a forehearth 212 as a conveying portion that is bolt-like climbing while rotating from the peripheral edge of the bottom portion 211, and a conveyance groove 213 formed in the foreman 212. The conveyance groove 213 has a V-shaped cross section perpendicular to the traveling direction, and if it is a rectangular parallelepiped workpiece such as an IC chip, it can be conveyed in a state where both surfaces are in contact with both surfaces of the V-shaped groove.

By driving the vibrating drive unit 22 to vibrate the hopper 21, the workpieces are sequentially conveyed in the circumferential direction.

The linear feeder 3 is connected to the above-mentioned hopper feeder 2 via a connection member 23.

The linear feeder 3 includes a groove 31 as a conveying portion linearly extending in the conveying direction, and a vibrating drive section 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 cross section of this conveyance groove 311 orthogonal to the conveyance direction is also V-shaped, and if it is a rectangular parallelepiped workpiece such as an IC chip, it is conveyed in a state where both surfaces are in contact with both surfaces of the V-shaped groove.

The connecting member 23 is also provided with a conveying 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 by the conveying groove of the connecting member 23.

The vibrating drive section 32 includes an electromagnet and a leaf spring supporting the groove 31, and vibration is transmitted from the vibrating drive section 32 to the groove 31 by the excitation of the electromagnet, and the groove 31 reciprocates. By driving the vibrating drive unit 32 to vibrate the groove 31, the workpieces transferred from the connection member 23 are sequentially conveyed downstream in the conveying direction.

The linear feeder 3 is provided with a judging unit 33 including a camera for judging the posture of the workpiece, and a workpiece removing unit 34 for removing the workpiece with an incorrect posture with air.

The return feeder 4 includes a groove 41 as a conveying part extending in parallel with the groove 31 of the linear feeder 3, and a vibrating drive part 42 located below the groove 41. The conveying direction is the opposite direction to the linear feeder. This return feeder 4 may also be configured to be driven by the vibration of the vibrating drive unit 32 of the linear feeder 3 instead of the vibrating 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 conveyance groove 411 also has a V-shaped cross section perpendicular to the conveyance direction, and if it is a rectangular parallelepiped workpiece such as an IC chip, it is conveyed in a state where both surfaces are in contact with both surfaces of the V-shaped groove.

In addition, the work removed by the work removal unit 34 on the linear feeder 3 is returned to the hopper 21 by the return feeder 4.

In addition, since the silo 5 is configured to feed the inputted workpieces into the hopper 21 from the nozzle portion on the lower end side along the funnel-shaped inner surface, the portion from the funnel-shaped inner surface to the nozzle portion becomes the conveyance path 51. The silo 5 is also configured to be driven by the vibrating drive unit 52 to smoothly convey the workpiece to the nozzle unit side.

In this embodiment, the vibrating machines 2, 3, 4, and 5 are represented as hopper feeder B, linear feeder L, return feeder R, and silo H, and the vibrating drive units 22, 32, 42, 52 are also Expressed 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 vibratory drive unit A (L, B, R, H). The component work device 1 includes a drive unit control device 6 that supplies power to the vibrating drive unit A (L, B, R, H), and a device for the operator to set the frequency and amplitude of the drive unit control device 6 Input device 7.

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

Fig. 6 shows the conventional controllers C1 to C4, which will be described later, but this embodiment separates the conventional controllers C1 to C4 into a drive unit control device 6 and an input device 7 as shown in Figs. 3 and 4(a) The arrangement of the drive unit control unit 6 on the unit U side corresponds 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 for driving 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 vibrating drive section A (L, B, R, H), and includes controlling the current flowing through the drive section A (L, B, R, H) (if the piezoelectric element is Is the voltage) H-bridge circuit. The bridge driver 62 is a circuit that drives the H-bridge circuit. The H-bridge circuit and the bridge driver 62 correspond to the switching part of a so-called converter.

The control unit 63 controls the amplitude, frequency, etc. of the electric power supplied to the vibrating drive unit A (L, B, R, H) via the bridge driver 62. The control unit 63 is composed of, for example, a digital calculation processing circuit including a memory that stores a predetermined program and a CPU that reads and executes the predetermined program. If 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. The 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 also serves as a display that obtains the output from the drive unit to the drive unit of the drive unit control device 6 through communication, the feedback value of the vibration sensor, the presence or absence of an external operating signal input, caution, warning, etc. The monitoring department functions.

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

And, 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 a housing and are assembled as the drive unit control device 6. As shown in FIG. 1, the driving unit control device 6 is installed on the base 10 together with the vibrating driving unit A (L, B, R, H) (22, 32, 42).

Between the drive unit control device 6 and the vibrating drive unit A (L, B, R, H), specifically between the vibrating drive unit A (L, B, R, H) and the drive circuit 61, and the vibration drive The parts A (L, B, R, H) and the amplitude sensor feedback circuit 65 are connected in the unit U by 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 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 ), a multi-core cable Cx is used in this embodiment. As shown in Figure 4(b), the multi-core cable Cx uses at least one power line Pw to supply 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 vibrating drive unit A (L, B, R, H). In addition to the LAN cable, the multi-core cable Cx can also be used with wires. With respect to the meaning that the internal wiring Cy is housed in the package U, the wiring 8 can be referred to as an external wiring in that the wiring 8 is pulled out of the package U and pulled back.

Of course, the energy line Pw is a device that can be used only 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 input device 7 and the drive unit control device 6 can 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), a silo connection port P (H), and each port P The internal wiring Cy is connected to each vibrating drive unit A (L, B, R, H) in the module U. As shown in FIG. 4( c ), each internal wiring Cy includes a power line Ca inputted as an AC output of the drive signal Sv of the drive circuit 61, and a feedback line F that feeds 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. Therefore, the operator obtains the setting input of the frequency and amplitude of the power supplied to the vibrating drive unit A (L, B, R, H), and displays the current setting status. The signal processing unit 72 recognizes the setting information D1 input to the setting input display unit 71 and provides the setting information D1 to the control unit 63 of the drive unit control device 6 via 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 one housing.

FIG. 5 shows the configuration of the display unit and input unit of the setting input display unit. The setting input display section 71 includes selection sections 71a1 to 71d1 for selecting which of the hopper feeder B, linear feeder L, return feeder R, and silo H, and a first setting section for each set amplitude and voltage value. 71a2 to 71d2, second setting parts 71a3 to 71d3 for each setting frequency. The amplitude and voltage are mainly used to adjust the conveying speed of the workpiece. The frequency is set according to the amplitude to effectively transmit the conveying force to the workpiece, or automatically adjusted according to the frequency and amplitude. The components indicated by 71a4 to 71d4 in the figure are the third setting part for soft start for slow start.

The speed of the workpiece is determined by these settings and the friction between the workpiece and the conveying path. In addition to the adjustment of the feed speed, the speed of the workpiece is also related to the adjustment of the distance between the workpieces. The adjustment is carried out by the operator in a timely manner while observing the actual operating conditions. The arrow X direction in Fig. 1 and Fig. 2 indicates the direction that the operator can easily use for installation, maintenance, etc., and the linear feeder 3 and the hopper feeder 2 are located on the side closer to the operator.

In addition, the supply port 1x of the component supply device 1 is connected to the supply target equipment TE, and in order to achieve control cooperation, the operation instruction unit OC (refer to FIG. 3) of the supply target equipment TE is sent to the control unit 63 of the component supply device 1 It is constructed by inputting start/stop signals and proceeding synchronously.

6 and 7 show a conventional component supply device 101 as a comparative example. In the element parts corresponding to Fig. 3, except for a part, the last two digits are equal to the hundreds sign. In this component supply device 101, each vibratory drive unit A (L, B, R, H) is connected to controllers C1 to C4, and each controller C1 to C4 integrates a drive circuit 161, a bridge driver 162, and a control unit. 163. Setting input display unit 171 and signal processing unit 172. In addition, when the component supply device 101 is installed in the supply target equipment TE of FIG. 2, the controllers C1 to C4 are arranged in a certain position of the supply target equipment TE, and the component supply device 101 and the controllers C1 to C4 need to be connected through the external wiring 108. Between the connection.

Therefore, only the number of controllers C1 to C4 is used to obtain places. Therefore, as shown in Figs. 8 and 9, by combining the functions of the controllers C1 to C4 in a single controller Cc, reduction in volume and increase are considered as an effective method.

However, when the controllers C1 to C4 are arranged in a certain position, from the viewpoint of the input device, the frequency of re-adjustment of vibration and frequency is high. If considering the re-adjustment caused by the variety, batch, surrounding environment, and static electricity It is preferable to install the controller Cc in a position that is easy for the operator to perform maintenance such as adjustment, cleaning of the conveyance path, and elimination of the work jam of the work. As shown in Figure 2, the arrow X direction is easy for the operator to operate, but since the linear feeder 3 and the hopper feeder 2 are located on the side close to the operator, the position of the input device has to be set at the position where the straight line is not installed. The feeder 3 and the other vacant space on the base 10 of the hopper feeder 2. However, for the above reasons, it is desirable that the input device be placed 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 the vibratory drive units close to the drive source of the drive hopper feeder B, linear feeder L, return feeder R, silo H, etc. on the base 10 22, 32, 42, 52 positions.

These are the opposite propositions, and it is a general rule that the parts feeder initially assembled in the appearance inspection device and the like does not have enough space for the controller Cc. Besides, the unmerged controllers C1~C4 are more obvious. Moreover, the number of external wirings 108 connecting the controllers Cc, C1 to C4 and the vibrating drive unit A (L, B, R, H) is still large.

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

Therefore, as shown in FIG. 3 and FIG. 4(a), this embodiment is configured by dividing its function into the drive unit control device 6 and the input device 7 with respect to the integrated controller Cc. As shown in FIG. 1, the drive The control device 6 is arranged in a blind spot on the base 10, that is, the inner side that is difficult to reach from the operator's hand and is difficult to handle. The drive control device 6 and each vibration are connected to the base 10 through internal wiring Cy. Wiring between vibrating drive parts A (B, L, R, H) (22, 32, 42, 52) of machines 1 to 4.

On the other hand, the input device 7 is pulled out from the unit U by the wiring (external wiring) 8 as a communication mechanism, and the operator can operate it at hand. The wiring 8 is extremely small in number from the wiring 108 of the conventional device shown in FIG. 6, and the wire type is a thin wire that is sufficiently flexible. In addition, it does not flow through the on/off signal of the inverter to generate strong electromagnetic waves. The drive signal.

Even if the component supply device 1 of the present embodiment configured in this way is packaged and transported to the position where the supply target equipment TE is set, the package except for the unit U, the input device 7, and the external wiring 8 has a built-in air mechanism for removing workpieces. , The number of assembly points is small, and the number of wiring is also small, so the wiring connection position after removal is also carried out within the minimum required, and the assembly work can also be performed very simply.

The input device 7 can adjust multiple parameters related to the vibratory drive unit A (L, B, R, H) shown in FIG. In the case of the linear feeder L, the setting parts 71a2, 71a3, 71a4, etc.) have the function of simultaneously adjusting multiple parameters. Therefore, unlike the input device arranged in the supply destination device 1, the input device 7 can be used as a control-only controller for the parts feeder 1 of the parts supply device that is the control target.

As described above, the component supply device 1 of the present embodiment is a vibration drive that assembles the conveying parts 21, 31, 41, 51 including the conveying parts as a component on the base 10, and vibrates the conveying parts 21, 31, 41, 51 Part A (L, B, R, H) (22, 32, 42, 52) of the parts supply device 1 of the vibrator 2, 3, 4, 5 is integrated in a part of the unit U to drive the vibration type Part A (L, B, R, H) inputs the drive unit control device 6 of the drive signal Sv and connects the vibrating drive unit A (L, B, R, H) and the drive unit control device 6 in the unit U installation.

In this way, the pulling back of the wiring Cy between the vibrating drive unit A (L, B, R, H) and the drive unit control device 6 is completed in the module U, and the wiring Cy is also shortened. Therefore, compared with the prior art, the number of wires protruding out of the module U is reduced, and there is almost no wiring margin. When the component supply device 1 is installed in the supply target equipment TE, the processing of the wiring will not be difficult to perform. Assembling with fewer work steps can also reduce the risk of wire breakage. In addition, since electromagnetic waves can be suppressed from being emitted outside the module U along with this, it is also possible to reduce the influence of noise on the surroundings.

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

In this way, the absence of the display unit and the operation unit eliminates the need to dispose the drive unit control device 6 in a position with good visibility and operability for the operator, thereby increasing the degree of freedom of disposition. Therefore, the blind space can be utilized as in the present embodiment, and the driving 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 for supplying electric power to the vibrating drive unit, a bridge driver 62 as a drive unit for driving the drive circuit 61, and a bridge driver as a drive unit. 62 A control unit 63 that controls the power to the vibrating drive unit A (L, B, R, H), and a serial communication circuit 64 as a setting information accepting 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 vibrating drive unit A (L, B, R, H), electromagnetic waves are easily emitted. However, in this embodiment, these parts It is housed in the unit U and wired through the internal wiring Cy in the unit U, so noise countermeasures are more effective.

In addition, in this embodiment, an input device 7 is further included, which is configured independently of the unit U, and includes a setting input display unit 7 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 vibrating drive unit A (L, B, R, H), and the input device 7 is appropriately arranged in a position where the operator can easily operate it.

In addition, the drive unit control device 6 and the input device 7 are connected through a serial line 8 including at least a communication line. With 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.

In addition, in this embodiment, a plurality of vibratory drive units 22, 32, 42, 52 are connected to the common drive unit control device 6. However, even if the drive unit control device 6 shares each vibratory drive unit 22, 32, 42 The drive of, 52 can also be reduced in size by commonality of the CPU, control power supply circuit, and housing in the drive unit control device 6. Furthermore, since the functions of the operation unit and the display unit are not included, there is no need to consider the operability of the operator. 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.

Above, an embodiment of the present invention has been described, but the specific structure of each part is not limited to the above-mentioned embodiment, and various changes can be made without departing from the spirit of the present invention.

For example, in the above embodiment, a touch screen type tablet computer is used in the input device 7, but it may also be a higher-level controller (PLC and server), or may be a smart phone. 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 component supply device, as long as the setting information receiving unit 64 of the drive unit control device 6 can communicate with an external input device. It can have the effect of taking the above-mentioned embodiment as the standard.

Alternatively, in the above-mentioned embodiment, the case where the control unit 63 includes the operation mode is described, but the above-mentioned controller may include the operation mode of which frequency and amplitude to start which vibration machine in the form of a table, etc., as setting information D1 is input to the setting information receiving unit 64.

In this case, as the setting information D1 from the upper controller, an analog signal for controlling the vibrating machine with a predetermined voltage, a predetermined current, and a predetermined frequency 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 combined to form a module, but as long as it is assembled into the module U, the drive unit control device 6 may be further disassembled, for example, the hopper feeder B, the linear feeder L, The electromagnets, weights, springs, etc. of the vibrating drive units 22, 32, and 42 of the feeder R are respectively integrally assembled with the bridge driver 62 and the drive circuit 61. The same applies to the case of using piezoelectric elements instead of electromagnets, and the transportation principle may be transportation by traveling waves other than transportation by elliptical vibration.

In addition, as shown in FIG. 11, as another example of the arrangement of the drive unit control device 6, a base 10a is arranged under the base 10, and a vibration-proof method such as vibration-proof rubber or vibration-proof spring is used between the base 10 and the base 10a. When 10b is connected, a recess 10a1 or the like may be provided on the side of the base 10a, and the drive unit control device 6 may be attached.

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

This configuration is not only effective as a blind spot, 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 metal. In addition, the base 10 and the base 10a can be combined. Since it is used as a heat sink, it can be expected that the heat dissipation characteristics will be improved and the components of the drive control device 6 can be reduced in size.

In addition, since the wiring does not extend from the module, there is no need to use the wiring as a shielded wire, etc., which is advantageous in terms of cost and convenience of wiring processing.

In addition, in the above-mentioned embodiment, the case where the hopper feeder B, the linear feeder L, the return feeder R, and the silo H are included as the vibrating machine is described. However, a part of the structure is, for example, only the hopper feeder B and the linear feeder. In the case of the feeder L, the return feeder R, only the hopper feeder B, the linear feeder L, and the linear feeder L only, the above-mentioned standard functions and effects can also be achieved. On the contrary, the situation is the same with respect to a vibration system that uses a vibration machine other than this as a part or all of it.

In addition, the operation unit is not limited to an encoder as long as it has a structure that satisfies the expected function, and may be a keyboard, buttons, variable resistor, liquid crystal display including a touch screen, voice control, etc.
