Abstract

PURPOSE:To enable a supplier to continuously and automatically supply parts, by reversely rotating a track so as to enable the supplier to perform self-restoration from a trouble of bitten parts when the parts to be supplied are bitten between the annular track and a regularly straightening wall and between a fall- off preventive wall fixed to the track and a rotary disk in the captioned supplier. CONSTITUTION:Parts are charged onto a disk 1 and fed to the periphery of the disk 1 by its rotation, moving along a regularly straightening wall 7 after the parts transfer to a track 2 having a fall-off preventive wall 3, and only the parts placed in a predetermined attitude are carried out from a supply outlet. Here the disk 1 and the track 2 are stopped by ceasing operation of each reversible electric motor 14, 15 for rotating the disk 1 and the track 2 if a supplier causes a trouble in which the parts are intruded into and bitten by a clearance between the periphery of the disk 1 and the fall-off preventive wall 3. Then the supplier is released from said bitten trouble by reversely rotating each electric motor 14, 15 after a predetermined time through a control circuit performing the logical decision in accordance with an output of rotation detectors 16, 17 additionally provided in these electric motors 14, 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts feeder. It goes without saying that a parts supply machine occupies an important position in an automated system, but malfunctions in the parts supply system often affect the success or failure of the automated system. Especially in vibrating bowl type feeders, the alignment track vibrates, which causes the parts to be fed to vibrate, and the parts to be fed get caught in the wiper of the alignment track, which is provided to prevent alignment, sorting, and overlapping of three parts. This often made it impossible to feed parts in an aligned manner, or caused blockage at the joint with the chute provided in contact with the discharge port of the vibratory bowl feeder. The rotating parts feeder (Japanese Patent No. 1129758) and the adaptive parts feeding apparatus (Japanese Patent Application No. 1983-23518) invented by the applicant have the structure shown in FIG. A truck 2, which has a disk l rotated by a variable speed electric motor 4 in the center and contacts the disk l at one point and turns upwardly from the disk 1, is driven by a variable speed electric motor 5. A drop-off prevention wall 3 formed of a part of a spherical surface is integrally formed with the track so as to be in contact with the outer periphery of the disk 1 over the entire circumference at the lower part of the inner side of the track. Variable speed electric motors 4 and 5 are mounted on intermediate disk 6. An alignment wall 7 is fixed to the intermediate disk 6 via a suitable object, and the alignment wall 7 is installed above the track 2 as close as possible. The parts to be supplied stored on the disk 1 are sent to the outer periphery of the disk by the rotation of the disk 1, transferred to the track 2 near the contact point between the disk 1 and the track 2 (this is called the transfer point), and then arranged. Only the parts to be supplied that move along the alignment wall 7 and have a desired orientation pass through and are discharged, and the parts to be supplied that are in incorrect orientation flow back to the disk l by interaction with the alignment wall 7. In order to efficiently align the discs 1 and the tracks 2, there is an optimum rotational speed depending on the characteristics of the parts to be supplied, so this is achieved by making the electric motor variable speed. but,
Overlapping parts to be supplied may get caught between the wiper provided on the alignment wall 7 and the track to prevent overlapping of the parts to be supplied, or thin parts to be supplied may be caught between the track 2 and the lower end of the alignment wall 7, There is a drawback that jamming occurs between the fall prevention wall 3 and the outer periphery of the disc 1, and the supply of non-supplied parts is stopped. An object of the present invention is to obtain a revolving parts feeder for the purpose of preventing supply stoppage.

The invention will be explained by examples. FIG. 2 is a sectional view for explaining the present invention. The disk 1 is driven by an electric motor 14 which is variable speed and reversible, and on the outer periphery of the disk 1, a track having a fall prevention wall 3 on the lower side is driven by an electric motor 15 which is variable speed and reversible. The variable speed and reversible electric motors 14 and 15 are fixed to an intermediate disk 6, and an alignment wall 7 is attached to the intermediate disk 6 above the track 2 via appropriate members. Disk detector 1 that detects rotation of disk 1
6 is attached to the rotating shaft of the electric motor 14, and a track detector 17 for detecting turning of the truck 2 is attached to the rotating shaft of the electric motor 15. Since the rotation of the electric motor is transmitted to the disc l and the track 2 via a speed reduction mechanism, the disc detector 16 is attached to the disc or the rotating shaft of the disc, and the track detector 17 is attached directly to the track or when the track turns. Even if it is attached to a mechanism, it does not change the gist of the present invention. Since the circle, plate, and track detectors detect the presence or absence of rotation or the number of rotations, they are used to detect the presence or absence of rotation or the number of rotations. This can be achieved by

FIG. 3 is a block diagram of a control circuit for implementing the present invention. A disk detector 16 is provided on the rotating shaft of a variable speed, reversible electric motor 14 that drives the disk l, and the output of the disk detector 16 is applied to a disk rotation determiner 22 via an intensifier 21. . The output of the disc rotation determiner 22 is applied to a logic circuit 23. Further, the track rotation detector 17 is attached to the rotating shaft of the variable speed, reversible electric motor 15 that drives the truck 2, and the output of the track rotation detector 17 is applied to the track rotation determiner 32 via the intensifier 31. The output of the track rotation determiner 32 is applied to the logic circuit 23. The logic circuit has an OR element and a flip-flop element. The output of the logic circuit 23 is applied to a sequence circuit 24 having a timer. The sequence circuit 24 generates a signal to normally rotate the variable speed, reversible motors 14 and 15 during normal operation, and when it receives an abnormal signal from the logic circuit 23, stops the rotation of the motors 14 and 15 after a certain period of time.
L, then a signal to reverse rotation for a certain period of time is issued, and after the reverse rotation is completed, a signal to stop for a certain period of time is issued, and then the normal state is returned. The output of the sequence circuit 24 is the electric circuit 114 and 15.
A reversal signal is applied to a switch 25 provided on the power supply side of the disc reversing device 26 and a track reversing device 36. The disc reversing device 26 is connected to the variable speed reversible motor 14 for driving the disc 1, and the track reversing device 36 is connected to the variable speed reversible motor 15 for driving the track. The disk reversing device 26 and the track reversing device 36 are connected to the switch 25.
connected to the power supply via.

Inserting a motor speed control circuit between the reversing device and the motor in the control circuit does not change the spirit of the present invention.

The present invention will be explained in detail with reference to FIGS. 2 and 3.

The parts to be supplied are placed on the disk 1. The disk 1 rotates at an appropriate number of rotations so that an appropriate amount of supplied parts passes through the transfer point and is transferred to the truck 2.

If the supplied part is a thin plate or a thin rod-like object, or if the bulk supplied part has a thin rod-like long protrusion, it will get stuck in the gap between the outer periphery of the disk 1 and the falling-off prevention wall 3, and it will get stuck. A car accident occurs. When the jamming occurs, the rotation of the disk 1 and the track 2 decreases and stops. During normal operation, a pulse train is generated from the disc rotation detector 16 and the track rotation detector 17 attached to the rotating shafts of the variable speed reversible motors 14 and 15.

The pulse train generated by the disc rotation detector 16 is applied to the neutralizer 21 and smoothed. The smoothed signal is applied to the disk rotation determiner 22, but no output is generated. Further, a signal from a track rotation detector 17 attached to the electric motor 15 for driving the track is applied to a neutralizer 31, smoothed, and applied to a track rotation determiner 32. When the track rotation detector 17 has a signal generated by rotation, the track rotation determiner 32 does not produce an output.

When the disc l is stopped due to the biting and the variable speed reversible motor 14 for driving the disc l stops, the disc rotation detector 1
6 no longer emits an output, and no signal enters the midterm unit 21, so there is no signal sent to the disc rotation determiner 22. The disk rotation determiner 22 generates a signal when the input signal disappears,
Indicates the stoppage of disk l. Furthermore, when the truck 2 stops rotating, the variable speed reversible electric motor 15 for driving the truck stops, so the output signal of the truck rotation detector 17 disappears, and the input to the mid-term unit 31 disappears, and the output signal of the mid-term unit 31 also disappears. , the input signal to the track rotation determiner 32 disappears, and the track rotation determiner 32 generates an output. Even if the inputs of the disk and track rotation determiners do not become O, but these determiners generate outputs when the inputs become smaller than a predetermined value, this does not change the spirit of the present invention. do not have. The outputs of the disc rotation determiner 23 and the track rotation determiner 32 are applied to the logic circuit 23, and the logical sum of the output signals of the disc rotation determiner 24 and the track rotation determiner 32 is generated in the logic circuit 23 and The voltage is applied to the flip-flop circuit built in the logic circuit 23, and when the disk l or track 2 stops, the logic circuit 23 continues to operate until the normal state is restored.
continues to produce output. The output of the logic circuit 23 is applied to a timer 24, and after an initial fixed period of time, the timer is applied to a switch 25.
The switch 25 is turned off and the variable speed reversible electric motors 14 and 15 are completely stopped.

When a certain period of time has elapsed, the timer 24 switches to the switch 25.
At the same time, the timer 24 operates the disc reversing circuit 26 and the track reversing circuit 36 to reversely rotate the variable speed, reversible electric motors 14 and 15, thereby rotating the disc 1 and the track. Rotate 2 in the opposite direction. The time for this reversal is called reversal time. Activating the reversing circuit 26 during the previous stop period does not change the spirit of the invention. After the reversal time has elapsed, timer 24
again issues a stop signal and disconnects switch 25. After or during the stop time, the signals to the disc reversing device 26 and the track reversing circuit are released, and when the stop time has elapsed, the variable speed reversible motors 14 and 15 rotate normally. As a result of this operation, the parts to be supplied that have become stuck in the gap between the disc l and the track 2 are moved back to the vicinity of the transfer point due to the reverse rotation of the disc l and the track 2, and are released from the jam. After the jam is released, the engine will stop for a certain period of time and resume normal operation. After the signal from the timer 26 to the switch 25 is released to ensure normal operation, the output of the timer 24 is output to the flip-flop circuit of the logic circuit 23 after a certain period of time has elapsed, that is, the rise time required for the motor to rotate normally. Reset. If the jam is not released after one attempt, this operation is repeated. Further, it does not change the spirit of the present invention to provide a timer and add a circuit that does not perform the operation to release the jam when the engine is first started to enter normal operation.

Next, the parts transferred to the track 2 pass only in a predetermined orientation due to interaction with the alignment wall 7, and parts with incorrect orientation are returned to the disk or are aligned with the track 2 during this process. A jamming occurs between the wall and the uniform wall 7.

In this way, when jamming occurs between the alignment wall 7 and the track 2, only the track 2 is forcibly stopped, and the disk 1 continues to rotate. The output of the track rotation detector 17 is O
Since the track circuit determiner 32 generates an output signal, the OR circuit at the input section of the logic circuit 23 generates an output,
Perform the above operation to reverse the track and disc to release the jam. Even if the circular plate 1 is stopped and only the track is reversed, the gist of the present invention does not change.

Further, it does not change the spirit of the present invention to provide a circuit that increases the torque generated by the electric motor during reverse rotation.

Although the operation has been explained above, even if the supplied parts are caught between the disc l and the falling-off prevention wall 3, the track 2 and the alignment wall 7
Even if the fall prevention wall 3 gets caught between the track 2 and the track 2, the track 2 will always stop or its rotation will be reduced. Further, the disc 1 is a variable speed, reversible electric motor 14
If the disk 1 is driven through a speed reducer or the reduction ratio is made small so that the electric motor can be rotated by the disk 1 when no power is applied to the electric motor 14, then the disk can be driven by a drop-off prevention wall 3. If the track 2 is rotated in the opposite direction when the supplied part is caught between them, the falling-off prevention wall 7 will be rotated, and the disc 1 will also be rotated in the opposite direction by the caught supplied part, so that the supplied part will be at the transfer point. It moves backwards to the vicinity and the bite is released. In order to operate in this manner, the disk rotation detector 16 attached to the rotating shaft of one disk l becomes unnecessary. A block diagram of a control circuit for this purpose is shown in FIG. A truck rotation detector 17 is provided which is attached to the rotating shaft of the truck 2 or to the shaft of a variable speed reversible electric motor 15 that drives the truck 2. The output of the track rotation detector 17 is applied to a track rotation determiner 32 via an intensifier 31. The track rotation determiner 32 generates an output when the signal from the track rotation detector 17 is 0 or less than a certain value, that is, when the truck stops or rotates slowly. The output of the track rotation determiner 32 is applied to the timer 24. The timer 24 is composed of a flip-flop circuit and a timer, and its output is applied to a switch 25 and a track reversing circuit 36 for reversing the variable speed reversible motor 15 of the track 2. When the track rotation determiner 32 detects that the rotation of the truck has decreased or stopped, a signal from the truck rotation determiner 32 is applied to the timer 24, which operates a flip-flop to operate the variable speed, reversible electric motor for driving the truck. 15 and a variable speed reversible electric motor 14 that drives the disc 1
After a certain period of time has elapsed, the timer applies a signal to the track reversing circuit 36 to configure a reversing circuit, and then applies a signal to the switch 35 to turn on the track reversing circuit 36. Reverse the electric motor 15.

Due to the biting of the supplied parts, the disk l is also rotated in the opposite direction,
The parts to be supplied are transported backwards beyond the transfer point and the jamming is released. The gist of the present invention is not changed by attaching a clutch to the rotating shaft of the disk 1 to disconnect the variable speed reversible motor 14 and the disk 1 at the time of reverse rotation of the disk 1 to ensure smooth reverse rotation of the disk 1.

After the rack 2 has been reversed for a certain period of time, the timer 24 applies a signal to the switch 35 to stop the variable speed reversible motor 15 again. After the variable speed reversible electric motor 15 is returned to a circuit in which it can rotate normally, the signal of the timer 24 cancels the stop signal applied to the switches 25 and 35 and returns the disk 1 and track 2 to normal operation. Rotate with rotation.

After a predetermined period of time has elapsed after normal rotation, the timer section issues a signal to release the flip-flop, and everything returns to normal operation.

If the jamming is not released even after normal operation is restored, the above operation is repeated. It does not change the spirit of the present invention to add a device that issues an alarm or automatically stops all operations when the jamming is not released even after this operation is repeated several times.

According to the present invention, the revolving parts feeder has a self-repair function, which makes it possible to improve the operating rate of an automated system, and greatly contributes to an unmanned production system.

Detailed Description of the Invention The present invention relates to a parts feeding machine. It goes without saying that a parts supply machine occupies an important position in an automated system, but malfunctions in the parts supply system often affect the success or failure of the automated system. Especially in vibrating bowl feeders, the alignment track vibrates, which causes the parts to be fed to vibrate, and the parts to be fed get caught in the wiper of the alignment track, which is provided to prevent alignment, sorting, and overlapping of three parts. This often made it impossible to feed parts in an aligned manner and caused blockages at the joint with the chute connected to the discharge port of the vibratory bowl feeder. Rotating parts feeder invented by the applicant (Patent No. 1129756)
and adaptive parts supply device (Japanese Patent Application No. 57-23518)
has the structure shown in Figure 1. Variable speed electric 4! J4
A truck 2, which has a disk l rotated at the center thereof, contacts the disk 1 at one point, and turns upwardly from the disk l, is driven by a variable speed electric motor 5. A falling-off prevention wall 3 formed of a part of a spherical surface is integrally formed with the track so as to be in contact with the outer periphery of the disk 1 over the entire circumference. Variable speed electric motors 4 and 5 are mounted on intermediate disk 6. An alignment wall 7 is fixed to the intermediate disk 6 via a suitable object, and the alignment wall 7 is installed above the track 2 as close as possible. The parts to be supplied stored on the disk 1 are sent to the outer periphery of the disk by 10 rotations of the disk, transferred to the truck 2 from near the contact point between the disk 1 and the track 2 (this is called the transfer point),
Only the supplied parts that move along the alignment wall 7 and have the desired orientation pass through and are discharged, while the supplied parts that have incorrect orientation move along the alignment wall 7.
It flows back into the disc 1 due to the interaction with the fluid. In order to efficiently align the discs 1 and the tracks 2, there is an optimum rotational speed depending on the characteristics of the parts to be supplied, so this is achieved by making the electric motor variable speed. However, overlapped parts to be supplied may get caught between the wiper provided on the alignment wall 7 to prevent overlapping of the supplied parts, and thin supplied parts may get stuck between the track 2 and the lower end of the alignment wall 7. Moreover, there is a drawback that jamming occurs between the falling-off prevention wall 3 and the outer periphery of the disk l, and the jamming occurs while the supply of the supplied parts is stopped, and the supply of the supplied parts is stopped. An object of the present invention is to obtain a revolving parts feeder for the purpose of preventing supply stoppage. The invention will be explained by examples. FIG. 2 is a sectional view for explaining the present invention. The disk l is driven by a variable speed reversible electric motor 14 that can be changed at variable speed and reversed, and on the outer periphery of the disk l there is a track having a fall prevention wall 3 on the lower side. 15. The variable speed reversible electric motors 14 and 15 are fixed to an intermediate disk 6, and an alignment wall 7 is attached to the intermediate disk 6 above the track 2 via appropriate members. A disk detector 16 for detecting the rotation of the disk l is attached to the rotating shaft of the electric motor 14, and a track detector 17 for detecting the turning of the truck 2 is attached to the rotating shaft of the electric motor 15. The rotation of the electric motor is controlled by a disk l through a speed reduction mechanism.
Since the information is transmitted to the track 2, the disc detector 16 is attached to the disc or the rotating shaft of the disc, and the track detector 17
The gist of the present invention will not be changed even if it is attached directly to the truck or to the turning mechanism of the truck. the disc detector;
Since the track detector detects the presence or absence of rotation or the number of rotations, it can be realized by an encoder, a rotary generator, a member attached to the rotating shaft, and a sensor using light, electricity, magnetism, etc. FIG. 3 is a block diagram of a control circuit for implementing the present invention. A disk detector 16 is provided on the rotating shaft of a variable speed reversible motor 14 that drives the disk l, and the output of the disk detector 16 is applied to a disk rotation determiner 22 via an amplifier 21. The output of the disc rotation determiner 22 is applied to a logic circuit 23. Further, the track rotation detector 17 is attached to the rotating shaft of the variable speed reversible motor 15 that drives the truck 2, and the output of the track rotation detector 17 is applied to the track rotation determiner 32 via the amplifier 31. Track rotation determiner 3
The output of 2 is applied to logic circuit 23. The logic circuit has an OR element and a flip-flop element. The output of the logic circuit 23 is applied to a sequence circuit 24 having a timer. The sequence circuit 24 generates a signal that causes the variable speed reversible motors 14 and 15 to rotate normally during normal operation, and when it receives an abnormal signal from the logic circuit 23, stops the rotation of the variable speed reversible motors 14 and 15 after a certain period of time. Then, it issues a signal to rotate in reverse for a certain period of time, and after the end of the reverse rotation, it issues a signal to stop for a certain period of time, and then returns to its normal state. The output of the sequence circuit 24 is applied to a switch 25 provided on the power supply side of the variable speed reversible motors 14 and 15, and a reversal signal is applied to the zero disc reversor 26 and the track reversor 36. The reversing device 26 is connected to the variable speed reversible electric motor 14 for driving the disk l, and the track reversing device 36 is connected to the variable speed reversible electric motor 15 for driving the track. The disk reverser 26 and the track reverser 3
6 is connected to a power supply via a switch 25. Inserting a motor speed control circuit between the reversing device and the motor in the control circuit does not change the spirit of the present invention. The present invention will be explained in detail with reference to FIGS. 2 and 3. The parts to be supplied are placed on the disk 1. The disk 1 rotates at an appropriate number of revolutions so that an appropriate amount of supplied parts passes through the transfer point and is transferred to the truck 2. If the supplied part is a thin plate or a thin rod-like object, or if the bulk supplied part has a thin rod-like long convexity, it will fit into the gap between the outer periphery of the disk l and the falling-off prevention wall 3, and it will get stuck. A car accident occurs. When the jamming occurs, the rotation of the disk 1 and the track 2 decreases and stops. During normal operation, a pulse train is generated from the disc rotation detector 16 and the track rotation detector 17 attached to the rotating shafts of the variable speed reversible electric motors 4114 and 15. The pulse train generated by the disk rotation detector 16 is applied to an amplifier 21 and smoothed. The smoothed signal is applied to the disk rotation determiner 22, but no output is generated. Similarly, a signal from a track rotation detector 17 attached to a variable speed reversible electric motor 1115 for driving the track is applied to an amplifier 31, smoothed, and applied to a track rotation determiner 32. When the track rotation detector 17 has a signal generated by rotation, the track rotation determiner 32 does not produce an output. When the disc 1 is stopped due to the jamming and the variable speed reversible electric fi 14 for driving the disc 1 is stopped, the disc rotation detector 16 stops outputting and no signal enters the amplifier 21. The signal to the plate rotation determiner 22 disappears. The disk rotation determiner 22 generates a signal when the input signal disappears, indicating that the disk l has stopped. Also, when the truck 2 stops rotating, the variable speed reversible motor 15 for driving the truck stops, so the output signal of the truck rotation detector 17 disappears, the input to the amplifier 31 disappears, and the output signal of the amplifier 31 also disappears. Therefore, the input signal to the track rotation determiner 32 disappears, and the track rotation determiner 32 generates an output. Even if the inputs of the disk and track rotation determiners do not become O, but these determiners generate outputs when the inputs become smaller than a predetermined value, this does not change the spirit of the present invention. do not have. The outputs of the disc rotation determiner 23 and the track rotation determiner 32 are applied to the logic circuit 23, and the logical sum of the output signals of the disc rotation determiner 24 and the track rotation determiner 32 is generated in the logic circuit 23 and The voltage is applied to a flip-flop circuit built in the logic circuit 23, and when the disk 1 or the track 2 stops, the logic circuit 23 continues to generate an output until the normal state is restored. The output of the logic circuit 23 is applied to a timer 24, and after an initial predetermined period of time, the timer sends a signal to the switch 25, which shuts off the switch 25 and completely stops the variable speed reversible motors 14 and 15. After a further certain period of time has elapsed, the timer 24 switches to switch 2.
5, the switch 25 is closed, and at the same time the timer 24 starts the disc reversal circuit 26 and the track reversal circuit 36.
is operated, the variable speed reversible electric motors @14 and 15 are rotated in the opposite direction, and the disc lk track 2 is rotated in the opposite direction. The time for this reversal is called reversal time. Activating the reversing circuit 26 during the previous stop period does not change the spirit of the invention. After the reversal time has elapsed, timer 24
again issues a stop signal and disconnects switch 25. After or during the stop time, the signals to the disc reversing device 26 and the track reversing circuit are released, and when the stop time has elapsed, the variable speed reversible motors 14 and 15 rotate normally. As a result of this operation, the parts to be supplied that have become stuck in the gap between the disc l and the track 2 are moved back to the vicinity of the transfer point due to the reverse rotation of the disc l and the track 2, and are released from the jam. After the jam is released, it stops for a certain period of time and resumes normal operation. After the signal from the timer 26 to the switch 25 is released to ensure normal operation, the output of the timer 24 is triggered by the flip of the logic circuit 23 after a certain period of time has elapsed, that is, the rise time required for the variable speed reversible motor to rotate normally.・Reset the flop circuit. If the jam is not released after one attempt, this operation is repeated. Further, it does not change the spirit of the present invention to provide a timer and add a circuit that does not perform the operation to release the jam when the engine is first started to enter normal operation. Due to the interaction with the alignment wall 7, the parts transferred to the track 2 pass only in a predetermined orientation, and the parts with incorrect orientation are returned to the disk, but during this process, the track 2 and the alignment wall 7
This causes a jam between the two. In this way, when jamming occurs between the alignment wall 7 and the track 2, only the track 2 is forcibly stopped, and the disk 1 continues to rotate. The output of the track rotation detector 17 becomes O, and the track circuit determiner 32 issues an output signal, so the OR circuit at the input section of the logic circuit 23 generates an output, and performs the above operation to reverse the track and disc. to release the jamming. Even if the disk 1 is stopped and only the tracks are reversed, the gist of the present invention does not change. Further, it does not change the spirit of the present invention to provide a circuit that increases the torque generated by the electric motor during reverse rotation. Although the operation has been explained above, even if the supplied parts are caught between the disc 1 and the falling-off prevention wall 3, the track 2 and the alignment wall 7
Even if the fall prevention wall 3 gets caught between the track 2 and the track 2, the track 2 will always stop or its rotation will be reduced. Further, the disk 1 is driven by the variable speed reversible electric motor 14 via a reduction gear, but by reducing the reduction ratio, the electric motor can be rotated by the disk 1 when the electric power 41114 is not applied. Then, when the supplied part is caught between the falling-off prevention walls 3 on the disc, if the track 2 is rotated in the opposite direction, the falling-off prevention wall 7 will rotate, and the caught supplied part will cause the disc l Since the parts to be supplied are also rotated in the opposite direction, the parts to be supplied are moved backwards to near the transfer point and are released from jamming. In order to operate in this manner, the disk rotation detection 1116 attached to the rotating shaft of the disk l becomes unnecessary. The block diagram of the control circuit for this is shown in the 4th block diagram.
It is a diagram. A truck rotation detector 117 is provided which is attached to the rotating shaft of the truck 2 or to the shaft of the variable speed reversible electric motor 15 that drives the truck 2. The output of the track rotation detector 17 is applied to a track rotation determiner 32 via an amplifier 31. The track rotation determiner 32 generates an output when the signal from the track rotation detector 17 is 0 or less than a certain value, that is, when the truck stops or rotates slowly. The output of the track rotation determiner 32 is applied to the timer 24;3. It will be done. Timer 24 consists of a flip flop circuit and a timer, and its output is connected to switch 25 and track 2.
is applied to the track reversing circuit 36 which reverses the variable speed reversible electric motor 41!15. When the track rotation determiner 32 detects that the rotation of the truck has decreased or stopped, a signal from the truck rotation determiner 32 is applied to the timer 24, which operates the flip-flop to drive the variable speed reversible motor 15 for driving the truck. The electric circuit to the variable speed reversible motor 14 that drives the disk l is disconnected by the switches 25 and 35, and after a certain period of time, the timer turns on the track reversing circuit 36.
After applying a signal to the switch 35 to configure a reverse rotation circuit, a signal is applied to the switch 35 to reverse the track drive variable speed reversible motor 15. Due to the biting of the supplied part, the disc 1 is also rotated in the opposite direction, and the supplied part is sent back past the transfer point, and the biting is released.6 In order to smooth the reverse rotation of the disc 1, the disc 1 is The gist of the present invention is not changed by attaching a clutch to the rotating shaft of l and separating the variable speed reversible electric motor Ifl&14 from the disk l when the disc l is reversed. After the truck 2 has been reversed for a certain period of time, the timer 24 applies a signal to the switch 35 to stop the variable speed reversible motor 15 again. After the variable speed reversible motor 15 is released and returned to a circuit in which it can rotate normally, the signal of the timer 24 cancels the stop signal applied to the switches 25 and 35 and causes the disk l and track 2 to rotate normally. Rotate with . After a predetermined period of time has elapsed after normal rotation, the timer section issues a signal to release the flip φ flop, and everything returns to normal operation. If the jamming is not released even after normal operation is restored, the above operation is repeated. Adding a device that issues an alarm or automatically stops all operations when the jamming is not released even after this operation is repeated several times does not change the purpose of Moe Kibatsu. According to the present invention, the revolving parts feeder has a self-repair function, which makes it possible to improve the operating rate of an automated system, and greatly contributes to an unmanned production system. 4.
