Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts feeder capable of automatically feeding a workpiece, such as a bolt, a stepped pin, a cap, a flanged ring, a nut, etc., to a processing machine or the like by controlling its posture.

[0002]

2. Description of the Related Art In a conventional parts feeder, a work is stored in a vibrating ball, and a transfer truss portion in which a plurality of spiral shaped rails and the like are arranged on an inner peripheral surface of the ball is provided. , Was composed.

[0003] The work is conveyed by the vibration of the ball so as to ascend a predetermined rail of the conveying trough portion, and the work in an appropriate posture is discharged from the rail and fed to a predetermined processing machine. In this case, the work having an inappropriate posture is sorted so as to fall from the rail and return to the bottom side of the ball storing the work.

[0004]

However, in the conventional parts feeder, the rails of the transport trough are spirally disposed along the inner peripheral surface of the ball, and the dimensions and shape of the work are changed. Was not easy to deal with.

For example, when the work is a bolt having a head portion and a shaft portion formed by threading a male screw, the rail is
Outer rails and inner rails are used with a gap that can support the lower surface of the head by inserting the shaft part, and transport and feed while the head is suspended by the inner and outer rails . However, when changing to feed a bolt with a larger outer dimension of the shaft, even if the outer rail is moved outward or the inner rail is moved inward, the inner and outer rails Because it is formed in an arc shape along the inner peripheral surface, the interval between the inner and outer rails partially corresponds to the changed shaft part, but the interval between the inner and outer rails in other parts However, since the work becomes smaller or larger than the changed shaft portion, it becomes impossible to accurately sort the work, and the entire transport trough portion has to be changed.

Further, since the work is stored in the vibrating ball, when the ball vibrates, interference noise between the work and the interference between the work and the ball are generated, so that the number of stored works is large. , The interference sound between the work is loud,
It was supposed to generate noise.

[0007] Further, the work is configured so that the work is spirally raised and fed in a conveying trough portion by vibration, and a centrifugal force acts on the work at the time of conveyance. It was necessary to design the section. For this reason, for example, even if an attempt is made to increase the work feed rate, to increase the frequency or amplitude and to increase the work transfer speed, the centrifugal force acting on the work increases, and the work cannot be accurately selected. Therefore, it was impossible to cope with the situation unless the entire transport trough was changed.

Similarly, the work is configured so that the work is spirally moved up the transport trough portion by vibration and is fed. When an attempt is made to sort and feed lightweight precision parts, the work is fed with reduced amplitude. Even if the feeding is attempted, the transport trough cannot be raised.

The present invention has been made to solve the above-mentioned problems, and can easily cope with a workpiece even when the size and the amount of the workpiece are changed, and can suppress noise at the time of the feeding. It is still another object of the present invention to provide a parts feeder that can easily design a workpiece even when workpieces of different weights and types are fed.

[0010]

A parts feeder according to the present invention is a parts feeder capable of controlling and feeding the posture of a work stored in a storage hopper, and transferring the work from the storage hopper. A conveyor unit, a vibration feeder unit connected to a tip end side of the conveyor unit for controlling and feeding the posture of the work, and receiving the work in an inappropriate posture discharged from the vibration feeder unit, A return chute for returning to the storage hopper, and the vibratory feeder section is configured to have a transport trough section capable of transporting the work in a substantially horizontal straight line, and a support bracket for supporting the transport trough section. A vibrating device for vibrating the support bracket, wherein the transport trough portion is disposed on a base portion side and receives a workpiece discharged from the conveyor portion; And a discharge port for discharging a work in a proper posture, disposed between the discharge port and the discharge port. A sorting section for dropping a work in a proper posture and transporting the work in a proper posture to the carry-out section; and a work receiving section in which the return chute is arranged below the sorting section; and And a return path for guiding the discharged work to the storage hopper.

The sorting section of the transport trough section is configured so that a workpiece in an inappropriate posture can be dropped from the left and right sides, and the work receiving section is disposed so as to cover the left and right sides below the sorting section. It is desirable to make it.

[0012] Further, at the entrance of the transport trough,
It is preferable that a throttle unit that restricts a supply amount of the work to the sorting unit is provided at a portion on a transport side to the sorting unit.

[0013] Further, it is desirable that the carrying entrance side of the transport trough section has lower rigidity than the sorting section side and is supported by the support bracket.

Further, it is preferable that the conveyor section is provided with a substantially cylindrical screw conveyor which rotates by providing a spiral groove for transferring the work on the inner peripheral surface.

[0015]

In the parts feeder according to the present invention, the work is transferred from the storage hopper to the carry-in entrance in the transfer trough of the vibration feeder by the operation of the conveyor. The work is then moved by the operation of the vibration feeder.
The work is transported from the carry-in entrance of the transfer trough to the sorting unit, where the work in the proper posture is carried to the carry-out opening, and the work in the inappropriate posture falls from the sorting unit to the work receiving unit of the return chute.

The work in the proper posture is discharged after being aligned and fed to a predetermined processing machine from the carry-out port. The work in the inappropriate posture is transferred from the work receiving portion of the return chute to the return path portion. It is transported and returned to the storage hopper, and these operations are repeated.

That is, in the parts feeder according to the present invention, the sorting section of the transport trough section in the vibration feeder section includes:
While the workpiece is aligned and transported in a substantially horizontal straight line, the workpiece in an inappropriate posture is dropped, and the workpiece in an appropriate posture is transported to the carry-out port. Unlike the trough part, the sorting part etc. can be formed in a straight line, so the dimensions of the work can be easily changed simply by widening or narrowing the spacing of the rails to be used, or by replacing the rails, etc. Can also be addressed.

Further, even when the work feed amount is changed, the work transfer direction is substantially horizontal and linear.
Since the centrifugal force does not act, it can be easily dealt with only by adjusting the frequency and amplitude of the vibrating device and adjusting the inclination of the transport trough in the transport direction.

Further, even when a lightweight work is fed, the work may be transported in a substantially horizontal straight line.
Since the centrifugal force does not act, it can be easily dealt with only by adjusting the frequency and amplitude of the vibrating device and adjusting the inclination of the transport trough in the transport direction.

Furthermore, even if the type of work changes,
Since the sorting unit and the like are configured to linearly align and transport the work in a substantially horizontal direction, compared to the conventional transport trough unit that is arranged in a curved shape in a vibrating ball, it does not require fine bending adjustment. The good part is that you can easily deal with and design.

In addition, since a large amount of the stored work is not vibrated, but only the work to be transferred vibrates, interference noise between the works is reduced, and noise during feeding can be suppressed. .

Therefore, in the parts feeder according to the present invention, even when the size and the feeding amount of the work are changed, the feeding can be easily dealt with, the noise at the time of the feeding can be suppressed, and the weight can be reduced. Even when a different type of workpiece is fed, the design can be easily performed.

The sorting section of the transport trough section is configured so that a work in an improper posture can be dropped from the left and right sides, and the work receiving section is disposed so as to cover the left and right sides below the sorting section. In addition, it is possible to efficiently remove workpieces with inappropriate postures, and even if the length of the sorting section is shortened, it is possible to easily sort workpieces between an appropriate posture and an inappropriate posture, making the vibration feeder compact. Can be

[0024] Further, if a throttle section for limiting the amount of work supplied to the sorting section is provided at a portion of the carrying trough section at the entrance of the carrying trough to the sorting section, the work to be transferred to the sorting section can be reduced. In addition, it is possible to suppress the overlap in the vertical and horizontal directions, to reduce the number of works to be eliminated as inappropriate postures, and to improve the feeding efficiency of the work in the proper posture.

Further, the rigidity of the carrying entrance side of the transport trough section is made lower than that of the sorting section and the supporting trough is supported by the support bracket.
The loading entrance side of the transport trough can make the amplitude larger than the sorting and exit sections, which can contribute to the uniformity of the work position at the loading section, and sort the work in the proper orientation. It is possible to increase the probability of transfer to the work, and to reduce the number of works to be eliminated in an improper posture in the sorting unit, thereby further improving the feeding efficiency of the work in the proper posture.

Furthermore, if the conveyor section is provided with a rotating substantially cylindrical screw conveyor provided with a spiral groove for transferring the work on the inner peripheral surface, when the screw conveyor rotates, the work is formed in the spiral groove. It is transported at a supply amount corresponding to the depth, and can be discharged to the entrance of the transport trough. Therefore, the supply amount from the loading port to the sorting unit can be kept constant, and the work transferred to the sorting unit can be prevented from overlapping in the vertical and horizontal directions. Can be reduced, and the feeding efficiency of a work in a proper posture can be improved.

Further, if the conveyor section is provided with a rotating substantially cylindrical screw conveyor provided with a spiral groove for transferring the work on the inner peripheral surface, a portion for transferring the work is provided.
It is a spiral groove formed on the inner peripheral surface of a substantially cylindrical shape, and can smoothly transfer the work without biting the work into the rotary drive portion. By the way, when transferring by a screw conveyor provided with a normal spiral blade, although the supply amount of the work can be kept constant, there is a possibility that the work may bite between the screw driven to rotate and the case surrounding the screw. .

Since the work receiving portion 71 is also fixed to the support bracket 33 connected to the vibration device 31, the work receiving portion 71 is conveyed forward on the bottom wall 72, and further guided at an inclination descending to the front side of the bottom wall 72. Then, the workpiece is transferred from the work receiving section 71 to the return path section 76 of the return chute 70, further returned to the storage hopper 9, and thereafter, the above-described operation is repeated.

Then, the parts feeder M of the first embodiment
In 1, when the outer diameter of the shaft portion 312 is changed, the nut 55 holding the suspension rail 50 on the holding brackets 53 and the nut 68 holding the guide rail 61 on the holding bracket 66. Loosen the gap h between the main rail 46 and the suspension rail 50 or the guide rail 61 so as to correspond to the shaft 312 of the bolt W1 whose dimensions have been changed, tighten the nuts 55 and 68, and operate the parts feeder M1. By the same operation as described above, the bolt W1 in an appropriate posture can be fed to a predetermined processing machine. Further, the outer diameter of the head 311 of the bolt W1 is changed, and the head 311 interferes with the receiving rail 48, and the shaft 312 is inserted into the gap h between the main rail 46 and the suspension rail 50.
Is not inserted, the position of the receiving rail 48 may be changed.

That is, in the parts feeder M1 of the first embodiment, the transport trough 4 in the vibration feeder 30
The selection part 45 of 0 is composed of three linear main rails 46.
Consisting of the receiving rail 48 and the suspension rail 50, the bolt W1 as a work is aligned and conveyed in a substantially horizontal straight line, the bolt W1b in an incorrect posture is dropped, and the bolt W1g in an appropriate posture is transferred to the carry-out portion 60. Unlike the curved transfer trough portion arranged in the conventional ball, the sorting portion 45 can be formed in a straight line, so that the spacing between the rails 46, 48, 50, 61, etc. to be used is made. Simply by widening or narrowing, or replacing the rail 48, etc.
Even if the size of the bolt W1 is changed, it can be dealt with. The operation of adjusting the distance between the rails 46, 48, 50, 61 and the like can be performed linearly in a direction perpendicular to the direction in which the bolt W1 is conveyed, so that fine adjustment can be easily performed. Even in the adjustment of attaching and detaching members, even in the direction orthogonal to the transport direction of the bolt W1,
Since it can be performed linearly, it is easy to see and fine adjustment can be easily made.

Further, even when the feeding amount of the bolt W1 is changed, the frequency and amplitude of the vibration of the vibrating device 31 are adjusted because the conveying direction of the bolt W1 is substantially horizontal and is not subjected to centrifugal force. In addition, it is possible to easily deal with the problem simply by adjusting the inclination of the transport trough 40 in the transport direction.

Further, even when a lightweight work is fed, the work may be transported in a substantially horizontal straight line.
Since the centrifugal force does not act, it can be easily dealt with only by adjusting the frequency and amplitude of the vibration device 31 and further adjusting the inclination of the transport trough 40 in the transport direction.

Furthermore, even if the type of work changes,
Since the sorting unit 45 is supported by the support bracket 33 extending in the front-rear direction and linearly aligns and transports the workpiece in a substantially horizontal direction, the transport trough unit is disposed in a curved line in a conventional vibrating ball. In comparison with the above, since it is not necessary to perform a delicate bending adjustment of a predetermined rail used for the sorting unit 45, it is possible to easily cope with the design, and
Manufacturing costs can be significantly reduced.

The parts feeder M1 of the first embodiment
Then, not all the bolts W1 as a large amount of stored work vibrate, but only the bolts W1 to be transferred vibrate, so that interference noise between the bolts W1 is reduced, and noise during feeding is suppressed. be able to.

Further, in the parts feeder M1 of the first embodiment, the first, second and third selection sections 45a, 45b, and 45c of the selection section 45 in the transport trough section 40 apply the incorrectly positioned bolts W1b from the left and right sides. It is configured to be able to fall,
The work receiving portion 71 of the return chute 70 is disposed so as to cover the left and right sides below the second and third sorting portions 45b and 45c. Therefore, the bolt W1b in the inappropriate posture can be dropped on the left and right sides on the rear side and the front side of the main rail 46, and can be efficiently removed. Bolt W between posture and improper posture
1 can be easily selected, and the vibration feeder unit 30 can be made compact.

Further, the parts feeder M of the first embodiment
In 1, the carry-in entrance 41 of the transport trough 40 protrudes rearwardly in a cantilever shape and is supported by the support bracket 33 with a lower rigidity than the sorting unit 45.

Therefore, when the transport trough section 40 vibrates due to the vibration of the vibration device 31, when the transport trough section 40
1 has an amplitude larger than that of the sorting section 45 and the carry-out section 60, and the bolt W is formed at the bottom 41 a of the carry-in section 41.
The posture of the bolt W1 can be made uniform such that the first axial direction is the front-back direction. As a result, if the posture is transferred to the first sorting part 45a of the sorting part 45 in that posture, the shaft part 312 is inserted into the gap h between the main rail 46 and the suspension rail 50, so that the posture becomes easy to be proper, and the sorting is facilitated. It is possible to reduce the number of bolts W1b to be removed in the incorrect posture in the part 45, and to improve the feeding efficiency of the bolt W1g in the proper posture.

Further, in the parts feeder M1 of the first embodiment, the transport trough section 40 of the conveyor section 10
As a device for transferring the bolt W1 to the carry-in port 41, a rotating substantially cylindrical screw conveyor 14 provided with a spiral groove 14a for transferring a workpiece on the inner peripheral surface is used. In this screw conveyor 14, when rotating, the bolt W1
It can be transported at a supply amount corresponding to the depth of the spiral groove 14a and discharged to the carry-in entrance 41 of the transport trough 40. Therefore, the supply amount from the carry-in part 41 to the sorting part 45 can be made constant, and the bolt W1 transferred to the sorting part 45 can be prevented from overlapping in the up-down direction or the left-right direction. The number of bolts W1b to be used can be reduced, and the feeding efficiency of the bolt W1g in a proper posture can be improved.

Further, the storage hopper 9 and the transport trough 40
Conveyor 10 for transferring the bolt W1 to the entrance 41
In this case, if a rotating substantially cylindrical screw conveyor 14 provided with a spiral groove 14a for transferring the work on the inner peripheral surface is used, the portion for transferring the bolt W1 of the screw conveyor 14 is provided on the substantially cylindrical inner peripheral surface. Spiral groove 14a formed
Therefore, the bolt W1 can be smoothly transferred without being bitten into the rotary drive portion. By the way, when transferring by a screw conveyor provided with a normal spiral blade, the supply of the work such as the bolt W1 can be kept constant, but the work is trapped between the screw driven to rotate and the case surrounding the screw. In rare cases, the transfer may be stopped.

If the above operation and effect are not considered,
Instead of the screw conveyor 14 of the embodiment, a bucket conveyor, a belt conveyor, a normal screw conveyor, a vibration feeder, or the like that can transfer a small amount of work may be used.

When a belt conveyor is used, for example, as shown in FIGS. 11 and 12, a weir plate 85a and the like are provided on the transfer path of the belt conveyor 84 so that the supply amount of the work W1 can be kept constant.

5 is an outlet 9a of the storage hopper 9, a guide chute 26,
It may be provided in the carry-in section 41.

Next, if the sorter is configured to linearly align and transport the workpiece in a substantially horizontal direction even if the type of the workpiece changes, a transport trough arranged in a curved shape within a conventional vibrating ball. The fact that it is not necessary to perform delicate bending adjustment as compared with the section and that it can be easily handled and designed will be described.
