Description

TECHNICAL FIELD The present invention relates to a parts supply apparatus that vibrates and conveys parts, and more particularly to a parts supply apparatus that reduces the number of wirings that need to be routed and improves the ease of incorporation into an application.

2. Description of the Related Art A parts feeder as disclosed in Patent Document 1, for example, is known as one of component supply devices that transport components by vibration. This type of parts feeder generally includes a bowl feeder and a linear feeder as vibrators for aligning and sorting input parts, and a return feeder for returning parts removed by the linear feeder to the bowl.

Each vibrator includes a conveying section having a running surface for parts and a vibrating drive section for vibrating this conveying section. It is assembled as a unit in a state where it is properly positioned.

Also, in order to drive them, a controller outside the unit is connected to each driving section through wiring. The controller is integrally composed of 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. , the driver inputs a drive signal to the vibrating drive unit, and the conveying path is vibrated.

For example, if the frequency and amplitude for vibrating the transport path are input from the input device, and if the driver has an inverter circuit, It is configured such that a corresponding drive signal is input to the drive section. As the principle of vibration, a type in which parts are conveyed by elliptical vibration and a type in which parts are conveyed by traveling waves are generally known.

Japanese Patent No. 6016101

By the way, when such a parts supply device is installed in the supply destination equipment, it is necessary to install a unitized vibrator at an appropriate location in the supply destination equipment, and to arrange a controller connected to the unit at an appropriate position in the periphery. be. Details are described below.

The parts feeder can change its ability to supply parts depending on the amplitude and frequency of the running surface, that is, the vibration conditions. In addition to the vibration conditions, there are various factors such as variations in workpiece lot shape, surface coating condition, generation of static electricity, ambient environment (humidity, temperature), and dirt on the running surface. Supply capacity is not necessarily one-to-one. Generally, the controller is used to adjust the amplitude and frequency at any time under the environment and lot conditions so that the capacity at the exit of the conveying section becomes the desired capacity. In particular, in a vibrator as a unit formed by combining a plurality of drive sections, the ability of the outlet of the conveying section cannot be adjusted without adjusting the conditions of the plurality of drive sections. Therefore, it is required that the controller be placed at a location that is easy for the operator to use so that the operator can adjust the supply capacity in an environment where the operator can monitor the conveying state of the vibrator.

In this case, the controller and each vibrator are connected by wiring, and the types of wiring include power lines, control signal lines, and communication lines. The wiring must be routed on the supply destination equipment. Therefore, when it is necessary to build equipment within a limited range, there are difficulties in wiring routes, piping duct space, and piping time, and there is a problem of competing for controller installation space in the supply destination equipment. It is inevitable.

In addition, if the destination equipment has a moving part such as an appearance inspection device or a taping machine, it will be difficult to install a controller around the vibrator due to the installation space in the destination equipment. If the wiring is too long, or if the wiring is routed carelessly, there is a high risk of disconnection due to contact with the movable part.

Furthermore, when the inverter circuit is switched ON/OFF by the driver in the controller, electromagnetic waves are radiated in the middle of the wiring, so there is a risk that the radiated noise to the equipment at the supply destination may cause malfunction of the equipment and a decrease in response time. .

Furthermore, when the parts are transported to the site in a packed state and assembled, the amount and types of wiring to be packed increases, resulting in a large number of wiring connection points, which requires a great deal of labor and time for setup. .

The present invention focuses on such a problem, and relates to a parts supply apparatus that vibrates and conveys parts. In particular, a parts supply apparatus that reduces the number of wires that need to be routed and improves the ease of incorporation into an application. intended to provide.

In order to achieve this object, the present invention takes the following measures.

That is, the component supply apparatus of the present invention is a component in which one or more vibrators, each having a conveying section for conveying a part and a vibrating driving section for vibrating the conveying section, are assembled as a unit on a base. A supply device, comprising a control unit for controlling electric power to the vibrating drive unit, a drive unit control device for inputting a drive signal to the vibrating drive unit , and the unit configured independently of each other. and an input device capable of communicating with the drive section control device, and the drive section control device is integrally incorporated into a part of the unit, and the vibration type drive section and the drive section control device are integrated. Devices are connected within the unit, and the input device has a display section and a processing section for providing setting information input to the display section to the control section via communication means, and the display section and the processing unit are accommodated in a single housing independent of the driving unit control device .

By doing so, the wiring between the vibrating drive section and the drive section control device is completed within the unit, and the wiring is shortened. As a result, the number of wires that go out of the unit is reduced compared to the conventional system, and when installing this parts supply device to the supply destination equipment, it is possible to assemble it with a small number of man-hours without worrying about wiring, and there is a risk of disconnection. can also be reduced. In addition, since the radiation of electromagnetic waves to the outside of the unit is suppressed accordingly, the influence of noise on the surroundings can also be reduced.
In addition, if the input device is configured independently of the unit and further includes an input device having a display section capable of communicating with the drive section control device, the drive section control device is arranged close to the vibrating drive section. However, the input device can be appropriately arranged at a position where the operator can easily operate it.

In particular, if the driving unit control device does not have a display unit and an operation unit, and receives setting information from outside the unit and inputs a driving signal to the vibration type driving unit, there is no display unit or operation unit. As a result, there is no need to place the drive unit control device at a location with good visibility and operability for the operator, and the degree of freedom in placement is improved. Therefore, it is possible to utilize the dead space and arrange the drive section control device at an appropriate position.

In this case, the drive unit control device includes a power supply unit that supplies power to the vibration type drive unit, a drive unit that drives the power supply unit, and a setting information reception unit that receives setting information to be input to the control unit. In the case of the present invention, although a drive signal accompanied by a switching operation flows from the power supply unit to the vibration type drive unit, electromagnetic waves are likely to be radiated. Noise countermeasures are particularly effective because they are wired together.

Further, if the input device has an operation unit capable of communicating with the drive unit control device, the drive unit control device is arranged close to the vibrating drive unit so that the input device can be easily operated by the operator. It can take any suitable form as it is placed in position.

In this case, if the drive section 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, so that the convenience of routing is improved and electromagnetic waves are generated. radiation can also be eliminated.

Furthermore, even if a plurality of vibrating drive units are connected to a common drive unit control device, and the drive unit control unit shares the drive of each vibrating drive unit, the CPU and the control power supply circuit in the drive unit control unit Miniaturization is possible by standardizing the case. Furthermore, it is not necessary to consider the operator's accessibility if the device does not have the functions of the operation unit and the display unit. In other words, further miniaturization can be achieved by not providing the functions of the operation section and the display section in the driving section control device.

Since the present invention has the structure described above, it relates to a parts supply device that vibrates and conveys parts, in particular, it reduces the number of wirings that need to be routed, and improves the ease of incorporation into an application, thereby providing excellent parts supply. Equipment can be provided.

FIG. 1 shows a parts feeder 1 of the present embodiment, which is also called a parts feeder, and serves as a vibrator for conveying works that are precision parts such as IC chips and minute coils. A feeder 2, a linear feeder 3 for further transporting the workpieces conveyed by the bowl feeder 2 in a fixed direction and sorting out workpieces with proper postures, and returning the workpieces determined to be inappropriate by the linear feeder 3 to the bowl feeder 2. A return feeder 4 that feeds the work and a hopper 5 that feeds the work into a bowl are provided. Each feeder 2, 3, 4 is arranged on a base 10, and assembled as a unit in an appropriately positioned state so that parts can be transferred smoothly in cooperation with each other. In particular, since the precision parts as described above are extremely small, the parts feeder for this type of application has the vibrators 2 to 4 densely arranged on a base 10 having an area of several tens of centimeters square. be done. Hereinafter, the feeders 2, 3, and 4 are also referred to as bowl B, linear L, return R, and hopper H together with hopper 5, as required.

FIG. 2 schematically shows such a component supply apparatus 1 together with supply destination equipment TE to which it is applied. This supply destination equipment TE, for example, such as a visual inspection device or a taping machine, performs inspection and processing on the supplied work, and like general factory equipment, it is possible to improve the space factor and productivity. From the point of view, the installation space is limited. For example, assuming that the supply destination equipment TE is 1 meter square or several meters square, a space is secured in one corner, the parts supply apparatus 1 is installed there, and the supply port 1x is connected to the supply destination equipment TE. , it is necessary to coordinate control. This embodiment improves the convenience of incorporation.

Returning to FIG. 1, the bowl feeder 2 comprises a bowl 21 which is a conveying section capable of accommodating the workpieces supplied from the hopper 5 which is a part feeding means shown by imaginary lines in the figure, and a vibrating driving section 22 which is positioned below the bowl 21. (The form is not shown in the figure). The bowl 21 has a circular bottom portion 211 with a bulging center in plan view, a track 212 as a conveying portion spirally climbing a slope while circling from the periphery of the bottom portion 211 , and a conveying groove 213 formed in the track 212 . have. The conveying groove 213 has a V-shaped cross section orthogonal to the running direction, and a rectangular parallelepiped work such as an IC chip is conveyed with two surfaces in contact with the two surfaces of the V-shaped groove.

The vibratory drive unit 22 has an electromagnet and a plate spring that supports the bowl 21 from below. When the electromagnet is excited, vibration is transmitted from the vibratory drive unit 22 to the bowl 21, causing the bowl 21 to torsionally vibrate. (In addition to the electromagnet, there is also a drive unit that uses a piezoelectric element.) By driving the vibrating drive unit 22 to vibrate the bowl 21, the workpieces are sequentially conveyed in the circumferential direction.

A linear feeder 3 is connected to the bowl feeder 2 via a connection block 23 .

The linear feeder 3 includes a trough 31 as a conveying portion that extends linearly along the conveying direction, and a vibrating drive portion 32 (only a portion of the leaf springs, which are constituent elements, is shown in the drawing) located below the trough 31. not).

A single conveying groove 311 extending in the horizontal direction is formed in the upper portion of the trough 31 in the longitudinal direction. The conveying groove 311 also has a V-shaped cross section orthogonal to the traveling direction, and a rectangular parallelepiped work such as an IC chip is conveyed with two surfaces in contact with the two surfaces of the V-shaped groove.

The connecting block 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 bowl feeder 2 are linked through the conveying groove of the connecting block 23. .

The vibratory drive unit 32 has an electromagnet and a leaf spring that supports the trough 31. When the electromagnet is excited, vibration is transmitted from the vibratory drive unit 32 to the trough 31, causing the trough 31 to reciprocate. By driving the vibrating drive unit 32 to vibrate the trough 31, the workpieces transferred from the connection block 23 are successively transferred downstream in the transfer direction.

The linear feeder 3 is provided with a discriminating section 33 including a camera for discriminating the posture of the work, and a work excluding section 34 for purging the work that is not in the proper posture with air.

The return feeder 4 has a trough 41 serving as a conveying section extending parallel to the trough 31 of the linear feeder 3 and a vibratory drive section 42 positioned below the trough 41 . The conveying direction is opposite to that of the linear feeder. The return feeder 4 may be configured to be driven by utilizing the vibration of the vibratory drive section 32 of the linear feeder 3 instead of the vibratory drive section 42 .

A single conveying groove 411 extending horizontally is also formed in the upper portion of the trough 41 in the longitudinal direction. The conveying groove 411 also has a V-shaped cross section perpendicular to the traveling direction, and a rectangular parallelepiped work such as an IC chip is conveyed with two surfaces in contact with the two surfaces of the V-shaped groove.

The work removed by the work removing section 34 on the linear feeder 3 is returned to the bowl 21 through the return feeder 4 .

The hopper 5 is configured to supply the workpieces to be fed into the bowl 21 along the funnel-shaped inner surface from the lower end nozzle portion, and the part extending from the funnel-shaped inner surface to the nozzle portion is the conveying path. 51. The hopper 5 is also driven by the vibrating drive section 52 so as to smoothly transfer the work to the nozzle section side.

In this embodiment, vibrators 2, 3, 4, and 5 are denoted as bowl B, linear L, return R, and hopper H, and vibratory drive units 22, 32, 42, and 52 are denoted as A(B), A(L). , A(R) and A(H). FIG. 3 is a block diagram showing a control system and an input system for each vibration type drive section A (L, B, R, H). This parts supply device 1 is configured so that an operator can set a driving unit controller 6 for supplying electric power to the vibrating driving units A (L, B, R, H), and the frequency and amplitude of the driving unit controller 6. and the input device 7 of

The vibrating drive section A (L, B, R, H) and the drive section control device 6 are integrated as a unit U on the base 10, and the input device 7 is configured separately from the unit U and installed at a different location. , for example, can be arranged at the operator's hand, and the two are connected via communication means 8 .

FIG. 6 shows conventional controllers C1 to C4, which will be described later. In this embodiment, the conventional controllers C1 to C4 are shown in FIGS. and the input device 7 , the driving unit control device 6 is arranged on the unit U side, and the input device 7 is separated via the communication means 8 .

3 includes an AC output drive circuit 61 as a 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. and an amplitude sensor feedback circuit 65 .

The drive circuit 61 is a circuit for inputting a drive signal Sv to the vibration type drive section A (L, B, R, H), and the current (voltage in the case of a piezoelectric element) flowing through the drive section A (L, B, R, H) ), including an H-bridge circuit that controls A bridge driver 62 is a circuit that drives this H bridge circuit. The H-bridge circuit and the bridge driver 62 generally correspond to the switching section of an inverter.

The control unit 63 controls the amplitude, frequency, etc. of the electric power supplied to the vibration type drive control unit A (L, B, R, H) via the bridge driver 62 . The control unit 63 comprises, for example, a digital arithmetic processing circuit including a memory storing a predetermined program and a CPU for reading out and executing the predetermined program. 62.

The serial communication circuit 64 is connected to the serial communication circuit 73 of the input device 7 via the wiring 8 as communication means, performs communication between the serial communication circuits 73 and 64, and controls the setting information D1 from the operator. Input to part 63 . This serial communication circuit 64 corresponds to the setting information receiving section of the present invention.
In addition to the information reception unit, the output of the drive unit control device 6 to the drive unit, the feedback value of the vibration sensor, the presence or absence of an operation signal input from the outside, caution, warning display, etc., are received from the drive unit through communication. It also functions as a monitor that displays information.

The amplitude sensor feedback circuit 65 receives the detected values of the amplitude sensors provided in the vibrators 2 to 5 and extracts the amplitude. is done.

The drive circuit 61, bridge driver 62, control unit 63, serial communication circuit 64, and amplitude sensor feedback circuit 65 are housed in one housing as shown in FIG. 1, and is installed on the base 10 together with the vibratory drive units A (L, B, R, H) (22, 32, 42).

Between the drive section control device 6 and the vibration type drive section A (L, B, R, H), specifically, between the vibration type drive section A (L, B, R, H) and the drive circuit 61, and between the vibration type drive section A (L, B, R, H) The equation driving section A (L, B, R, H) and the amplitude sensor feedback circuit 65 are connected within the unit U by wires Ca and Cb that are as short as possible. Here, a set of these wirings Ca and Cb is set as one internal wiring Cy.

On the other hand, in this embodiment, a multi-core cable Cx is used for the wiring 8 serving as communication means for connecting between the input device 7 and the driving section control device 6 shown in FIG. 4(a). As shown in FIG. 4(b), at least one of the multicore cables Cx is used as a power line Pw to supply electric power of a predetermined voltage from the drive unit control device 6 to the input device 7. (here, four lines) are used as serial communication lines S for transferring setting information D1 relating to each vibration type drive unit A (L, B, R, H). A harness or the like can be used as the multicore cable Cx in addition to a LAN cable. In contrast to the meaning that the internal wiring Cy is contained within the unit U, the wiring 8 can be called an external wiring in that it is drawn out of the unit U and routed.

Of course, the power line Pw is for enabling the input device 7 to be used only by connecting it to the driving section control device 6, and the input device 7 may be provided with a separate power source. Along with this, the communication between the input device 7 and the driving section control device 6 can be made wireless.

The drive unit controller 6 is provided with a bowl feeder connection port P (B), a linear feeder connection port P (L), a return feeder connection port P (R), and a hopper connection port P (H). and each vibrating drive section A (B, L, R, H) are connected by internal wiring Cy in the unit U, respectively. Each internal wiring Cy includes, as shown in FIG. 4(c), a power line Ca for sending an AC output, which is the driving signal Sv of the driving circuit 61, and a feedback line Cb for feeding back the detected value of the amplitude sensor.

The input device 7 shown in FIG. 3 has a setting input display section 71 , a signal processing section 72 and a serial communication circuit 73 . The setting input display unit 71 is of a touch panel type, and accepts from the operator setting inputs relating to the frequency and amplitude of the power supplied to the vibration type drive units A (L, B, R, H), and displays the current setting state. display. The signal processing section 72 recognizes the setting information D1 input to the setting input display section 71 and provides the setting information D1 to the control section 63 of the drive section control device 6 via the serial communication circuits 73 and 64 . The signal processing unit 72 also stores the current setting information D1 and causes the setting input display unit 71 to display it. These setting input display section 71, signal processing section 72 and serial communication circuit 73 are accommodated in one housing.

FIG. 5 shows the configuration of the display/input section of the setting input display section 71 . The setting input display section 71 includes selection sections 71a1 to 71d1 for selecting any one of the linear L, bowl B, return R, and hopper H, and first setting sections 71a2 to 71d1 for setting the amplitude and voltage value for each of them. 71d2, and second setting units 71a3 to 71d3 for setting frequencies for each. Amplitude and voltage are mainly used to adjust the workpiece transfer speed, and frequency is set so that the transfer force is efficiently transmitted to the workpiece according to the amplitude, or auto-tuning is performed according to the frequency amplitude. Reference numerals 71a4 to 71d4 in the drawing are a third setting section for soft start that slows down the start.

The work speed is determined by these settings and the friction between the work and the transport path. The work speed is related not only to the adjustment of the supply speed but also to the adjustment of the distance between works. Adjustments are made in a timely manner by the operator while observing the actual operating conditions. The arrow X direction in FIGS. 1 and 2 indicates the direction in which the operator can easily access for installation, maintenance, etc., and the linear feeder 3 and the return feeder 2 are positioned closer to the operator.

Then, the supply port 1x of the parts supply apparatus 1 is connected to the supply destination equipment TE, and the control unit 63 of the parts supply equipment 1 are configured to synchronize by inputting a start/stop signal to .

6 and 7 show a conventional component supply device 101 as a comparative example. Element parts corresponding to those shown in FIG. Controllers C1 to C4 are connected to the respective vibrating drive units A (L, B, R, H) of the component supply device 101. The controllers C1 to C4 each include a drive circuit 161, a bridge driver 162, a control A unit 163, a setting input display unit 171, and a signal processing unit 172 are incorporated integrally. When installing the component supply device 101 in the supply destination equipment TE of FIG. It was necessary to connect by wiring 108 .

Therefore, the number of controllers C1 to C4 takes up space. Therefore, as shown in FIGS. 8 and 9, one effective means is to reduce the bulkiness by integrating the functions of the controllers C1 to C4 in one controller Cc.

However, when considering where to place the controller Cc, from the viewpoint of the input device, the frequency of readjustment of vibration and frequency is high. Considering maintenance such as a minor stoppage for clearing clogging, it is desirable to install the controller Cc at a location that is easily accessible to the operator. In FIG. 2, the arrow X direction is the direction that the operator can easily access. It has to be installed in another blank space on the base plate 10 where the feeder 2 is not installed. However, for the above reasons, it is desirable to place the input device as close to the operator as possible.

Conversely, from the standpoint of the drive unit controller 6, each vibratory drive unit 22, 32, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, 42, It is desirable to place it at a location close to 52.

These are contradictory propositions, and the parts feeder incorporated in the visual inspection apparatus generally does not even have enough space for installing the controller Cc. Even more so for controllers C1-C4 that are not integrated. Furthermore, the number of external wirings 108 connecting between the controllers Cc, C1-C4 and the vibrating drive units A (L, B, R, H) is still large.

As described above, the existence of the external wiring 108 is not only inconvenient for wiring processing and setup of the apparatus, but also is undesirable from various viewpoints such as the influence of radiation noise.

Therefore, in the present embodiment, the functions of the integrated controller Cc are separated into the driving section control device 6 and the input device 7 as shown in FIGS. 6 is arranged in a dead space on the base 10 as shown in FIG. are connected by internal wiring Cy on the base 10.

On the other hand, the input device 7 is pulled out from the unit U through wiring (external wiring) 8 as communication means so that the operator can operate it at hand. Compared to the wiring 108 of the conventional device shown in FIG. 6, the number of wirings 8 is much smaller. No drive signal flows.

Even if the parts supply apparatus 1 of this embodiment configured in this way is packed and transported to a place where the supply destination equipment TE is set, the unit U, the input device 7, and the external wiring 8 are contained in the package. In addition, since the air mechanism for removing the workpiece is included, the number of assembly points is small and the number of wires is small, so the number of wire connection points after removal is minimized, and the setup work can be performed remarkably easily. It is a thing.

The input device 7 includes a plurality of operation units such as encoders operated by an operator (for example, a linear In terms of L, it has setting units 71a2, 71a3, 71a4, etc.), and has a function of simultaneously adjusting a plurality of parameters. Therefore, unlike the input device provided in the supply destination facility 1, the input device 7 can be used as a dedicated controller for controlling the parts feeder 1, which is a parts supply device to be controlled.

As described above, the component supply device 1 of this embodiment includes the transport units 21, 31, 41, and 51 that transport components, and the vibrating drive unit A ( L, B, R, H) (22, 23, 24, 25) and vibrators 2, 3, 4, 5 are assembled as a unit on a base 10, and the vibration A drive section control device 6 for inputting a drive signal Sv to the type drive section A (L, B, R, H) is integrally incorporated in a part of the unit U, and the vibration type drive section A (L, B, R, H) and the drive unit controller 6 are connected within the unit U.

In this way, the wiring Cy between the vibrating drive section A (L, B, R, H) and the drive section control device 6 is completed within the unit U, and the wiring Cy is also shortened. For this reason, the number of wiring lines extending out of the unit U is reduced compared with the prior art, and the excess wiring length is almost eliminated. Assembly can be performed in a limited number of man-hours, and the risk of wire breakage can be reduced. In addition, since the radiation of electromagnetic waves to the outside of the unit U is suppressed accordingly, the influence of noise on the surroundings can also be reduced.

Further, the driving unit control device 6 does not include a display unit and an operation unit, and receives setting information D1 from outside the unit and inputs a driving signal Sv to the vibration type driving units A (L, B, R, H). is configured to

In this way, since there is no display section or operation section, the driving section control device 6 does not need to be arranged at a place with good visibility and operability for the operator, and the degree of freedom in arrangement is improved. Therefore, it is possible to use the dead space as in the present embodiment to dispose the drive unit control device 6 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 type drive unit, a bridge driver 62 as a drive unit that drives the drive circuit 61 unit, and a vibration type drive unit A ( (L, B, R, H)) through a bridge driver 62 as a driving unit, and a serial communication circuit 64 as a setting information receiving unit for receiving setting information to be input to the control unit 63. and

That is, since the drive signal Sv accompanying the switching operation flows from the drive circuit 61, which is the power supply unit, to the vibration type drive units A (L, B, R, H), electromagnetic waves are likely to be radiated. is accommodated in the unit U and connected by the internal wiring Cy in the unit U, noise countermeasures are particularly effective.

In this embodiment, the input device 7 is configured independently of the unit U and has an operation section and a setting input display section 71 as a display section capable of communicating with the driving section control device 6 . In this way, the driving section control device 6 is arranged close to the vibrating type driving section A (L, B, R, H), and the input device 7 is arranged at a position that is easy for the operator to operate. can take

A serial line 8 including at least a communication line connects between the driving section control device 6 and the input device 7 . With such a configuration, the number and thickness of the serial lines 8 can be reduced, which improves the convenience of wiring and eliminates the fear of radiation of electromagnetic waves.

Furthermore, in this embodiment, the plurality of vibrating drive units 22, 32, 42, and 52 are connected to the common drive unit control device 6. , 32, 42, and 52, it is possible to reduce the size by sharing the CPU, control power supply circuit, and case in the drive unit controller 6. FIG. Furthermore, since it does not have the functions of an operation unit and a display unit, there is no need to consider operator accessibility. In other words, further miniaturization can be achieved by not providing the functions of the operation section and the display section in the drive section control device 6 .

Although one embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention.

For example, in the above embodiment, a touch panel type tablet is used as the input device 7, but a host controller (PLC or server) or a smart phone may be used. The communication means is also not particularly limited, and may be Blue-tooth, Wifi, light, or the like.

In this case, as shown in FIG. 10, only the drive section control device 6 should be attached to the parts supply device, and communication between the setting information receiving section 64 of the drive section control device 6 and an external input device should be made possible. If so, the effects according to the above-described embodiment can be obtained.

Alternatively, in the above embodiment, the case where the control unit 63 is provided with operation patterns has been described. , this may be input to the setting information reception unit 64 as the setting information D1.

In this case, as the setting information D1 from the host controller, an analog signal for controlling the amplitude of the vibrator at a predetermined voltage, a predetermined current, and a predetermined frequency is input to the setting information reception unit 64 of the drive unit controller 6. Become.

In the above-described embodiment, the drive unit control device 6 is collectively modularized. The electromagnets, weights, springs, or the like that constitute the driving units 22, 32, and 42 may be disassembled, and the bridge driver 62 and the driving circuit 61 may be integrated into each of them. The same is true when a piezoelectric element is used instead of an electromagnet, and the transport principle may be transport by elliptical vibration, transport by traveling waves, or the like.

10, a base 10a is arranged under the base 10, and an anti-vibration rubber or anti-vibration spring is provided between the base 10 and the base 10a. In the case where they are connected by a vibration isolating means 10b such as the above, the drive unit control device 6 may be attached by providing a concave portion 10a1 on the side of the base 10a.

Alternatively, it is also effective to dispose the drive unit controller 6 between the base 10 and the base 10a, as indicated by the dashed line in FIG.

Such an arrangement is not only effective in utilizing dead space, but also has an electromagnetic shielding effect when the base 10, the base 10a, and the housing (chassis) of the driving unit control device 6 are made of metal. Since the base 10 and the base 10a can be used as a heat sink, it can be expected that the heat dissipation characteristics are improved and the module itself of the drive unit control device 6 can be made small.

In addition, since the wiring is not protruded from the unit, there is no need to take measures such as shielding the wiring, which is advantageous in terms of cost and ease of wiring.

Further, in the above-described embodiment, a case where the bowl B, the linear L, the return R, and the hopper H are provided as the vibrator has been described. Even in the case of L only, linear L only, etc., the same effects as described above can be obtained. Conversely, the situation is the same for a vibration system including a part or all of a vibrator other than this.

Further, the operation unit is not limited to an encoder as long as it satisfies the desired function, and may be a sheet key, push button, variable resistor, liquid crystal display with a touch panel, voice operation, or the like.
