[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a linear vibration feeder for supplying a coil spring.

[0002]

2. Description of the Related Art When attempting to supply coil springs one by one to the next process using a vibration feeder, a problem arises in how the coil springs are supplied in a tangled manner. To prevent it.

In order to cope with this, a bowl vibration feeder using torsional vibration is disclosed in, for example, Japanese Utility Model Publication No. Sho 52-4.
No. 693 discloses that an air outlet is directed upward at a connection point between a wide portion of a spiral track for transferring a coil spring attached to an inner wall of a bowl (a bowl-shaped container) and a narrow portion for aligning coil springs one by one. Provided, and blow off the coil spring that protrudes from the narrow part with the blast air to select it.
The blown coil spring collides against a small cylindrical repellent member provided above the narrow track of the bowl cover to relieve entangling and return it to the inside of the bowl. However, in this device, since the loosened coil springs are only loosened by the collision with the repellent body, not all of the collisions are unraveled, or the loosened coil springs exist in a large vibration state. Since it is returned to the inside of the bowl, the loosened material often becomes entangled again, resulting in poor efficiency as a whole, and requires a large amount of compressed air to loosen the coiled spring. As a result, the sound of blowing air is inevitably increased, which is not preferable from the viewpoint of the working environment.

Also, in Japanese Patent Publication No. 55-5445, a coil spring protruding beyond a predetermined size on a spiral track of a bowl vibrating feeder is selectively removed by blowing off the jet air to drop into the bowl. And collect them in the center of the bottom of the bowl with another jet of air,
The coil spring is blown upward to collide with the inner wall surface of a fin-shaped collision object provided in the center of the bowl, and the coil spring that has been loosened is returned to the inside of the bowl. This device also has exactly the same drawbacks as the prior art described above.

[0005] A vibration feeder for supplying components not by the above-mentioned torsional vibration but by linear vibration, that is, the components are circulated between a supply trough and a return trough, which linearly vibrate in opposite directions, while being sandwiched between the troughs. A linear vibration feeder is proposed by the present applicant in which the parts are supplied to the next process by an alignment track fixed to the return trough at a position close to the supply trough (Japanese Patent Application No. SHO 57-57).

In the first embodiment, the first trough 1 , the second trough 2 , and the detangling device 3 are fixed on the common base 101 as described above.
Numeral 01 is further installed on the floor via an anti-vibration rubber 102 to prevent the vibration of the linear vibration drive units P, Q, R from being transmitted to the floor. The periphery of the common base 101 to the first near the bottom of the trough 1 and the second tigers <br/> off 2 is covered with a thin plate 103 screwing into a common base 101.

The linear vibration feeder according to the first embodiment of the present invention is configured as described above, and its operation will be described below.

1 to 3, a large number of coil springs m are stored in the vibration hopper H (not shown). When the photoelectric sensor 71 detects that the coil spring m has been completely transferred, the vibration device of the vibration hopper H Is activated for a predetermined time and the coil spring m
Are cut out and supplied to the second trough 2 and then automatically stopped. A large amount of coil springs m on the second trough 2 are moved rightward in FIGS. 2 to 4 under the vibration of the linear vibration driving units Q and R, and are transferred to the first trough 1 on the bottom surface of the second trough 2 . It is guided downward (FIGS. 5 and 6) and guided by the guiding surface 21, and is transferred from the opening 22 into the first trough 1 through the opening 12 of the first trough 1 . 2 and 6, the coil springs m are scattered, but actually exist at a higher density.

The coil spring m on the first trough 1 is moved leftward in FIGS. 1, 2 and 4 under the vibration of the linear vibration driving unit P, and is turned to the circular opening 13 at the downstream end of the first trough 1.
From there, it falls inside the introduction pipe 31 of the kami-no-kashi device 3, which is aligned with this, and is guided into the cylindrical body 32a. As shown in FIG. 5, FIG. 7, and FIG. 8, since the compressed air is ejected from the ejection port 35a of the air ejection nozzle 35 disposed at one end of the cylindrical body 32a, the coil introduced in the vicinity thereof The spring m collides with the flat plate 34 fixed to the upper wall portion of the inner wall of the cylindrical body 31a while performing a helical movement as a whole along the inner circumference of the cylindrical body 32a and being slightly pumped to the downstream side, The coiled coil spring m is loosened.
That is, due to the impact of the collision, the two flat plates 34 are cut into one of the coil springs m, and the other coil spring m
Is entangled by the collision of the coil spring m that follows. Further, there are a plurality of flat plates 34, and the coil springs m that have been hit by the flat plates 34 many times while being fed to the downstream side are reliably loosened. When the coil spring m passes under the partition plate 37, the coil spring m is completely disentangled and rises in the discharge pipe 33 via the cylindrical body 32b while riding on the jet airflow while changing from helical motion to linear motion. And
It is dropped and discharged onto a transfer table 4 integrated with the second trough 2 .

The coil spring m discharged to the transfer table 4 is transferred to the alignment track 5 by the downward inclined surface (FIG. 5) of the transfer table 4 toward the alignment track 5, as shown in FIG. Are aligned in the groove. At this time, the coil spring m which is not transferred to the alignment track 5 is the second trough 2
To fall. The coil spring m on the alignment track 5 receives the vibration of the second trough 2 and is moved rightward in FIGS. The unwound coil spring m passes through the gate block 6 provided downstream as it is (FIG. 6). For example, when there is a coil spring m that is slightly entangled during the vibration transfer on the alignment track 5, Is
The coil spring m cannot pass through the gate block 5 and stops on the upstream side before the gate block 5 (FIG. 9). Since the stop stops the light beam between the light emitting element 71a and the light receiving element 71b of the photoelectric sensor 71 for a predetermined time or more, it is determined to be stopped by a controller (not shown), and the air cylinder 64 is operated by a signal from the controller. The gate block 6 is raised, and then the solenoid valve (not shown) of the compressed air supply pipe 81 is opened, and the coil spring m containing air ejected from the air ejection port 8 is introduced into the second trough 2 . It is blown out and eliminated (FIG. 10). Subsequently, in response to a signal from the controller, the ejection of air is stopped, and the gate block 6 is lowered to return to the original state.

The coil spring m that has passed through the gate block 6
Is transported further downstream on the alignment track 5, but when the transport is in an overflow state, that is, when the state of the excessive supply and the contact are continued for a predetermined time or more, the light emitting element 72a of the photoelectric sensor 72 Since the light beam between the elements 72b is interrupted for a predetermined time or longer, the controller determines that this is an overflow and the linear vibration drive unit P of the first trough 1
Is stopped, and the solenoid valve (not shown) of the compressed air supply pipe 36 that blows out air to the cylindrical body 32a of the unwinding device 3 is closed. Further, when the cancellation of the overflow condition is detected, the controller restarts the operation of the first trough 1 and the detangling device 3.

The linear vibration feeder 100 according to the first embodiment of the present invention is constructed and operates as described above, and has the following advantages as compared with the above-mentioned conventional example. That is, in each of the examples of Japanese Utility Model Publication No. 52-4693 and Japanese Patent Publication No. 55-5445, the coiled coil spring m is blown up by the blast air, and is simply applied to a cylindrical repellent body or a garbage-shaped collision object. Since loosening is performed only by collision, the loosening efficiency is low and a large amount of compressed air is required. Further, the coil spring m that has been loosened is returned to the bowl where the coil spring m is stored in a vibrating state. Therefore, the linear vibrating feeder according to the first embodiment of the present invention has the loosening of the coil spring m fixed at a predetermined pitch. Collision with a plurality of flat plates 34, the flat plate 34 is inserted into a coil spring,
Further, since the plate spring 34 is caused to collide with the flat plate 34 many times during the pressure feeding to the downstream side, it is ensured that the coil spring m is entangled. 2 (or the first trough 1 ) rather than returning it to the transfer track 4 to the alignment track 5, the coil spring m loosened is less likely to become entangled again, and the overall loosening efficiency is extremely high. is there.
Therefore, the amount of compressed air used is extremely small, and the noise of the compressed air is reduced, which is preferable from the viewpoint of the working environment. Further, the conventional example uses a bowl vibration feeder based on torsional vibration, whereas the linear vibration feeder according to the first embodiment of the present invention uses linear vibration, so that the maintenance and adjustment of the vibration mechanism is simple. Also have.

On the other hand, an L-shaped air blow pipe 92 is fixed to the common base 101 by a band 91 so that the tips of the rising portions are aligned below the mesh 95, and the mesh 9
5 and the end of the rising portion of the air blow pipe 92 are connected by a bellows 93. The air blow pipe 92
Is connected to a solenoid valve (not shown).

[0036] The leno loosening device 3 is disposed at a position higher than the side wall of the tiger <br/> off 2 by a support 85 which is bolted 86 to the common base 101 (FIG. 13),
As shown in FIG. 11, an introduction pipe 96 for guiding the coil spring m to the entanglement device 3 is provided with a first trough 1.
Of the mesh 95, and hang down to just above the mesh 95. Further, instead of the discharge pipe 33 in the first embodiment, the second half of the upward semi-cylindrical portion of the cylindrical body 32b is used.
The guide trough 9 is inserted into an opening 97 provided in the cylindrical surface on the trough 2 side.
8, the guide trough 98 is provided such that its surface has a gentle downward inclination toward the transfer table 4 and its discharge end is located directly above the transfer table 4.

The linear vibration feeder 200 according to the second embodiment of the present invention is configured as described above, and its operation will be described below.

11 and 12, the coil spring m that has reached the circular opening 14 of the first trough 1 rises up the introduction pipe 96 by air blown up from the air blow pipe 92, and is then guided to the disentangling device 3. Since the mesh 95 is attached to the circular opening 14, the coil spring m
Is prevented from falling and does not fall into the air blow pipe 92. The entangled coil spring m is disentangled in the entanglement device 3 in the same manner as in the first embodiment, and then transferred to the downstream side, from the guide trough 98 through the opening 97 in the downstream portion of the cylindrical body 32b. It is discharged to the transfer table 4. The coil spring m that has reached the transfer table 4,
As in the first embodiment, the data is supplied to the next step via the alignment track 5 and the gate block 6.

The linear vibration feeder 200 according to the second embodiment of the present invention is constructed and operates as described above.
The differences from the first embodiment are as follows. That is, with respect to the transfer of the coil spring m to the transfer table 4, in the first embodiment, the coil spring m is dropped from the discharge pipe 33 to the transfer table 4, whereas in the second embodiment, the rolling from the surface of the guide trough 98 is mainly performed. , So transfer stand 4
The transfer from the second embodiment to the alignment track 5 is smoother in the second embodiment. In addition, the transfer stand 4
During the transfer process, the displacement energy required to raise the coil spring m from the lowest position to the highest position is determined by transferring the coil spring m from the discharge pipe 33, as is apparent from a comparison between FIGS. Since the first embodiment in which the air is dropped onto the table 4 is larger, and the energy required for the jet air or blown air is smaller in the second embodiment, the required amount of compressed air is reduced accordingly. Compared with the conventional example, the second embodiment of the present invention ensures that the entangled coil spring m is loosened, and returns the unwound coil spring m to the place where the coil spring is stored in a vibrating state. However, as in the case of the first embodiment, the loosening efficiency is high because the transfer is performed to the alignment track 5, and the consumption of the compressed air is extremely small due to these effects.

In the linear vibration feeder according to the third embodiment of the present invention, the linear vibration feeder according to the first or second embodiment corresponds to the first embodiment except for a part of the detangling device. Since the feeder is composed of the same components as those of the feeder, the drawings and description thereof are omitted, and only different portions will be described.

The detangling device 30 in the third embodiment
Is the cylindrical body 32a of the detangling device according to claim 1.
14 and 15, a cylindrical body 32c as shown in FIGS. 14 and 15 is provided, and the other portions are the same as those in the entanglement device in the first embodiment or the second embodiment. Cylinder 32c is disposed so as to protrude in an opening provided in its lower longitudinal gyrus which rotates about its axis
A plurality of rod-like members 38 fixed at a predetermined pitch along the axis are provided on the upper wall portion of the rolling member 134 and the inner wall of the cylindrical body 32c.

The coil spring m, which is introduced from the first trough 1 to one end of the cylindrical body 32c of the unraveling device 30 by the same operation as the linear vibration feeder according to the first or second embodiment rotates. By being recoiled on the surface of the elongate rotating body 134 and colliding with the rod-shaped member 38,
The entanglement is loosened. The coil spring m loosened while repeatedly colliding with the plurality of rod-shaped members 38 is discharged to the downstream side, and thereafter, the same configuration and operation as those of the linear vibration feeder in the first embodiment or the second embodiment. Thereby, the coil spring m which is not entangled is supplied to the next step.

According to the detangling device of the third embodiment,
Rotate the impact of coil spring m on a flat or rod-shaped member
Because of the recoil on the surface of the longitudinal rotating body 134 ,
The amount of air used is further greatly reduced, and the recoil is caused by the recoil on the surface of the longitudinal rotating body 134 having a large inertial weight.
A coil spring m having a large weight per piece can also be processed.

Although the embodiments of the present invention have been described above, the present invention is, of course, not limited to these, and various modifications can be made based on the technical concept of the present invention.

For example, in each of the above-described embodiments, the transfer in the detangling device 3 is performed by pneumatic feeding.
The transfer may be assisted by inclining the cylinders 32a, 32b slightly downward along their axes.

In the first embodiment, the coil spring m
Rises in the discharge pipe 33 due to the jet air from the air jet port 35a. For example, when the weight of the coil spring m is large, the cylindrical body 3 just below the discharge pipe 33
Another air outlet for assisting the coil spring m to be blown up may be provided on the bottom surface of 2b.

In each embodiment, a plurality of flat plates 34 or rod-like members 38 having a predetermined pitch are fixed to the upper wall of the inner wall of the cylindrical body 32a in the detangling device 3 as a collision object of the coil spring m. It is even more preferable that the upper wall is not required to be fixed, and is fixed at a place where the collision energy for loosening is maximum.

In FIGS. 14 and 15, the rod-shaped member against which the coiled coil spring m collides is a U-shaped round bar. However, a triangular, polygonal, ring-shaped, or simple linear shape is not a limitation. It belongs to the scope of the technical idea of the invention.

In each embodiment, the photoelectric sensors 71 and 72 are used as the detecting means of the coil spring m. However, other known detecting means, for example, an industrial TV camera using a CCD image sensor may be used.

In each embodiment, the air cylinder 64 is used to drive the gate block 6 to be raised and lowered. However, it is needless to say that this may be another known cylinder device, for example, a hydraulic cylinder.

In each embodiment, the coil spring m
Although the jet air from the air jet port 8 is used for the removal, this may be removed by attracting and moving with an electromagnet.

In each embodiment, the alignment track 5
Although the timing gate 55 is provided at the downstream end of the above, it may be omitted depending on the next step for receiving the coil spring m.

In the above embodiment, the photoelectric sensor 71 is provided in the vicinity of the gate block 6 and upstream thereof for detecting the coiled coil spring m. If the coil spring m does not arrive for more than the time, it may be determined that the gate block 6 is stopped at the upstream end face.

Further, in each embodiment, the coil spring m
Although the linear vibration feeder which supplies the above is exemplified and described, it is assumed that a coil-shaped component such as a bulb filament which is easily tangible is equivalent to the coil spring m in the present invention.

[0055]

As described above, according to the linear vibration feeder of the present invention, a plurality of flat plates or rod-shaped members are collided many times, so that the coil spring can be loosened securely and the coil spring can be loosened. Is supplied to the next process as it is via the alignment track, so that reentanglement is suppressed and the loosening efficiency is high, so that the amount of compressed air required for loosening the coil spring is significantly reduced. Therefore, the sound of blowing air is reduced, and the effect of improving the working environment is great. Furthermore, since the feeder uses linear vibration, adjustment and maintenance are easier than a feeder that uses torsional vibration.
