Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coil spring supply device that continuously supplies coil springs in an aligned state.
[0002]
[Prior art]
In the assembly process of machines and the like, it is necessary to continuously supply parts used in the assembly process.
[0003]
For this reason, conventionally, as a component supply device (part feeder), a vibration feeder that conveys and aligns a large amount of components by vibration and an air feeder that separates a large amount of components by air pressure and sends them one by one.
[0004]
The vibration feeder has an advantage that a large amount of parts can be charged at once and continuously supplied. However, in the vibration feeder, for example, when trying to supply a coil spring as a component, the coil spring is conveyed in small increments due to minute amplitude vibration, so that the coil spring cannot be entangled and conversely promotes the coil spring entanglement. There was a possibility. Therefore, the coil spring which is easily entangled cannot be continuously supplied.
[0005]
The air feeder can supply the coil springs in an aligned state. However, since the air feeder requires a large-sized air supply device that consumes a large amount of energy, there is a problem that the air feeder itself is large and expensive, and the operation cost is high. Furthermore, in order to continuously supply coil springs that are easily entangled in an aligned state, it is necessary to frequently put the coil springs into the air feeder little by little, and there is a problem that the capacity cannot be increased.
[0006]
[Problems to be solved by the invention]
In consideration of the above-described facts, the present invention has an object to obtain a coil spring supply device that can continuously supply coil springs that are easily entangled, and that can reduce the device and operating costs with a small size and large capacity. .
[0011]
[Means for Solving the Problems]
  Claim1The coil spring supply device of the invention according to,allIt is formed in a cylindrical shape with a bottom as a body, and has flat blades provided along the axial direction on its inner peripheral surface, and is installed rotatably around the central axis to accommodate a large amount of coil springs A container, drive means connected to the container for rotating the container around a central axis, and a groove corresponding to the coil spring, wherein one end of the groove is located in the container and the other end is the A chute that is disposed at one end in the axial direction of the container in a state of being inclined downward toward the outside of the container, slides and discharges the coil spring that is dropped and supplied from above in the container in the longitudinal direction. And equipped withThe flat blades are inclined with respect to the radial direction of the container so that the tip side is located downstream of the root side in the rotation direction of the container..
[0012]
  Claim1In the coil spring supply device described in the above, a large amount is put into a cylindrical container and collected in the lower part of the container.TakoThe il spring is wound up on the blades installed on the inner surface of the container as the driving means rotates about the central axis of the container, and falls from the upper part in the container.
[0013]
A part of the coil spring falling from the upper part in the container falls on the chute and is inserted into a groove provided in the chute. Since the chute is inclined downward toward the outside of the container, the coil spring inserted into the groove slides in the longitudinal direction of the coil spring one by one by gravity and is discharged out of the container in an aligned state.
[0014]
Further, even when the coil spring is entangled, the entanglement of the coil spring is easily eliminated by the impact of the entangled coil spring falling from the upper part in the container.
[0015]
  Therefore, a large amount of coil springs that are easily entangled can be continuously supplied. Furthermore, since air pressure is not used, a small, inexpensive and low operating cost coil spring supply device can be obtained.
  A coil spring supply device according to a second aspect of the present invention is a pair of coils for detecting the presence or absence of a coil spring on the transfer path at different positions in the transfer direction of the coil spring in the transfer path of the coil spring outside the container. It is characterized by providing a sensor.
[0016]
  The coil spring supply device of the invention according to claim 3 is:Claim 1 orThe coil spring supply device according to claim 2, wherein the depth and width of the groove are larger than the outer diameter of the coil spring and smaller than the outer dimension when the coil spring is entangled, and reciprocally move on the groove. It is possible to provide an exclusion means for removing the entangled coil spring from the groove when the entangled coil spring is inserted into the groove.

In the coil spring supply device according to claim 3, since the depth and width of the groove provided in the chute are larger than the outer diameter of the coil spring and smaller than the outer dimension when the coil spring is entangled, When the coil spring is inserted into the groove, a part of the entangled coil spring protrudes to the upper part of the groove.
[0018]
In this case, even if the entangled coil spring slides in the groove toward the outside of the container, it engages with the exclusion means installed so as to be able to reciprocate on the groove, so that it is not discharged outside the container. Further, when the exclusion means reciprocates on the groove of the chute, only the entangled coil spring protruding to the upper part of the groove can be pushed out of the groove and dropped again into the container.
[0019]
Therefore, even if the entangled coil spring is inserted into the groove, it is possible to supply a spring that is easily entangled without clogging.
[0020]
  A coil spring supply device according to a fourth aspect of the present invention comprises:1 toOf claim 3Any one itemThe coil spring supply apparatus described above is characterized in that the container is installed so as to be inclined so that the installation side of the chute is lowered.
[0021]
In the coil spring supply device according to the fourth aspect, since the container is inclined so that the chute installation side of the container is lowered, the coil spring in the container is concentrated and collected on the chute installation side of the container. For this reason, coil springs that fall from the upper part of the container due to winding by the blades are also concentrated on the chute installation side of the container, the number of coil springs that fall on the chute increases, and the probability that the coil spring is inserted into the groove increases.
[0022]
Therefore, the extraction efficiency of the coil spring is improved, and it is possible to supply a spring that is continuous, stable and easily entangled. Further, even when the number of coil springs in the container is reduced, the coil spring can be stably supplied.
[0023]
  A coil spring supply device according to a fifth aspect of the present invention comprises:1The coil spring supply device according to any one of claims 4 to 6, wherein the chute is installed so as to be substantially horizontally shifted downstream of the vertical center line of the container in the rotational direction.
[0024]
In the coil spring supply device according to claim 5, the chute is installed in consideration of the fact that the coil spring falling from the upper part in the container falls with the horizontal movement to the downstream side in the rotational direction due to the inertial force accompanying the rotation of the container. The position is shifted substantially horizontally from the vertical center line of the container to the downstream side in the container rotation direction. Thereby, a chute is installed in a position where there are many falling coil springs, and the probability that the coil springs are inserted into the grooves increases.
[0025]
Therefore, the extraction efficiency of the coil spring can be further improved, and a spring that can be continuously and more stably entangled can be supplied.
[0026]
A coil spring supply device according to a sixth aspect of the present invention is the coil spring supply device according to the fifth aspect, wherein the chute is installed in a position shifted downstream in the rotation direction of the container and is in contact with the central axis side of the container. It is characterized by comprising a guide portion that is installed and guides the coil spring that is dropped and supplied from above into the groove.
[0027]
In the coil spring supply device according to claim 6, since the guide portion is provided in connection with the chute, the coil spring dropped from above is not only directly inserted into the groove, but also rotated on the guide portion. The coil spring dropped and supplied with the horizontal movement in the downstream direction is guided into the groove by the guide portion, so that the coil spring is easily inserted into the groove.
[0028]
Therefore, the coil spring can be quickly inserted into the groove, and the spring can be supplied continuously and stably and quickly.
[0029]
A coil spring supply device according to a seventh aspect of the present invention is the coil spring supply device according to the sixth aspect, wherein the upper surface of the guide portion is inclined downward toward the groove.
[0030]
In the coil spring supply device according to the seventh aspect, since the upper surface of the guide portion is inclined downward toward the groove, the guide performance to the groove of the coil spring supplied and dropped on the guide portion is improved. Furthermore, even when the coil spring that is dropped and supplied onto the inclined guide portion is bounced, the direction of the bounce is limited to the groove side, so that the coil spring is more easily inserted into the groove.
[0031]
Therefore, the coil spring can be inserted into the groove more quickly, and the spring can be supplied continuously and more stably and quickly.
[0032]
  A coil spring supply device according to an eighth aspect of the present invention comprises:1The coil spring supply device according to any one of claims 7 to 7, wherein one of the side walls on the side of the central axis of the container of the both side walls of the groove is made lower than the height of the other side wall. It is said.
[0033]
In the coil spring supply device according to claim 8, since the wall height of the groove on the central axis side of the container is lower than the wall height on the opposite side, the coil spring guided to the groove by the guide portion is Colliding with the opposite wall restricts the coil spring from passing through the groove, making it easier to insert the coil spring into the groove.
[0034]
Therefore, the extraction efficiency of the coil spring can be further improved, and it is possible to continuously supply a spring that is more stable and quick to be entangled.
[0035]

[0040]
FIG. 4 shows the configuration of the drive unit 200. In the driving unit 200, a pair of rollers 202A and 202B are attached to the frame 218 in parallel to and parallel to the bottom surface of the frame 218, and the container 104 is detachably mounted on the pair of rollers 202A and 202B. It has become so. A pulley 203A is provided at one end of one roller 202A, and is connected to the pulley 205A via a timing belt 206A. Similarly, a pulley 203B is also provided at one end of the other roller 202B, and is connected to the pulley 205B via a timing belt 206B. Both the pulley 205A and the pulley 205B are connected to the output shaft of the motor 204. Further, the timing belt 206A is maintained at a predetermined tension by a tension pulley 216A, and the timing belt 206B is maintained at a predetermined tension by a tension pulley 216B. As a result, the driving force of the motor 204 is transmitted to the rollers 202A and 202B, and the rollers 202 are rotated in the same direction. Accordingly, the container 104 placed on the rollers 202A and 202B is rotated in the direction opposite to the rotation direction of the rollers 202A and 202B.
[0041]
Also, the roller 202A and the roller 202B are provided with a rubber ring 208A and a rubber ring 208B, respectively, for preventing slipping, and the container 104 rotates without slipping by contacting the container 104 via the rubber ring 208A and the rubber ring 208B. It can be made to.
[0042]
In addition, the frame 218 is provided with screwed legs 222 whose leg lengths can be adjusted at four corners on the bottom, so that the frame 218 can be inclined by adjusting the leg length of each leg 222 so that the inclination angle of the container 104 can be adjusted. It has become.
[0043]
Further, the driving unit 200 is configured to reciprocate a slider 308 described later on the groove 304. That is, the lower end portion of the rod 210 is rotatably connected to a predetermined position of the plane portion of the pulley 205A, and one end portion of the rod 212 is connected to the upper end portion of the rod 210 so as to face the installation direction of the container 104. The other end of the rod 212 is connected to the gear train 214 so that the reciprocating vertical movement of the upper end of the rod 210 accompanying the rotational motion of the pulley 205A is converted into the reciprocating rotational motion of the gear train 214 via the rod 212. It has become. Further, a pinion 215 installed on the output shaft of the gear train 214 is engaged with a slider 308 provided with a rack, so that the reciprocating rotational motion of the gear train 214 is converted into the reciprocating linear motion of the slider 308. In order to adjust the connecting position of the rod 210 at the connecting portion between the pulley 205A and the lower end of the rod 210 in the radial direction of the pulley 205A, a long hole 209 is provided in the pulley 205A with the long axis as the radial direction of the pulley 205A. Yes. Thus, the stroke length of the slider 308 can be adjusted by adjusting the connection position of the lower end of the rod 210 to the pulley 205A.
[0044]
Therefore, the container 104 and the slider 308 can be driven by a single motor 204, and the coil spring supply device 100 can be downsized.
[0045]
A fixed disk 306 is fixedly installed on the installation side 300 installation side of the frame 218, and the fixed disk 306 closes the opening of the container 104 rotated on the rollers 202A and 202B, thereby allowing the container 104 to move. The coil spring 102 is prevented from overflowing from an opening provided at one end.
[0046]
A hole 309 is provided at a position that is horizontally shifted by a predetermined distance from the vertical center line of the container 104 of the fixed disk 306 to the downstream side in the rotation direction of the container 104, and the chute 302 has one end portion through the hole 309. It is inserted into the container 104 and installed in a state of being inclined downward toward the outside of the container 104.
[0047]
As shown in FIGS. 5 and 6, the chute 302 includes a groove 304 provided over the entire length in the longitudinal direction and a flat guide portion 302 </ b> A provided on the container 104 center axis side of the groove 304. Configured. Further, the chute 302 is installed with an inclination of about 5 ° so that the groove 304 installation side is lowered. Note that only the upper surface of the guide portion 302A may be inclined downward toward the groove 304 without tilting the chute 302.
[0048]
As shown in FIG. 6, the width of the groove 304 is larger than the outer shape of the coil spring 102 and smaller than the outer dimension of the entangled coil spring 102. Further, the height of the side wall of the groove 304 opposite to the central axis of the container 104 is larger than the outer shape of the coil spring 102 and smaller than the outer dimension of the entangled coil spring 102. On the other hand, the side wall height of the groove 304 on the central axis side of the container 104 is set lower than the height of the side wall of the groove 304 opposite to the central axis of the container 104. As a result, the coil spring 102 is quickly inserted into the groove 304 without passing through the groove 304. The side wall height of the lower side of the groove 304 is determined so that the coil spring 102 outside the groove 304 cannot contact the coil spring 102 in the groove 304 when the slider 308 described later blocks the groove 304. (See FIG. 6A).
[0049]
As shown in FIG. 5, a slider 308 is installed on the opposite side of the chute 302 from the central axis side of the container 104 so as to reciprocate on the groove 304 so as to engage with the entangled coil spring 102 protruding from the groove 304. Has been. As described above, the slider 308 is driven by the drive unit 200 and always moves back and forth on the groove 304. Further, as shown in FIG. 7, one end of the slider 308 (the right end in FIG. 7) reciprocates in a range from the surface on the container 104 side of the fixed disk 306 to the end of the chute 302 in the container 104. The stroke length of the slider 308 is determined by the combination of the gear train 214 and the connection position between the pulley 205A and the rod 210. The length of the slider 308 is determined so that one end is always inside the container 104 and the other end is always outside the container 104.
[0050]
A tube 310 is connected to the outlet end of the chute 302 (the end outside the container 104) in order to convey the coil spring 102 discharged from the container 104 to a predetermined position in an aligned state. Moreover, the stop part 312 is installed in the tube exit end part, the conveyed coil spring 102 is stopped, and it can take out one by one.
[0051]
A pair of sensors 314 are provided outside the tube 310 to detect the presence or absence of the coil spring 102 in the tube 310. When the pair of sensors 314 detects that the coil spring 102 is in the tube 310, the motor 204 is stopped, and when the pair of sensors 314 detects that the coil spring 102 is not in the tube 310, the motor 204 is operated. ing. As a result, when a predetermined number of coil springs 102 are accumulated in the tube 310, the rotation of the container 104 and the reciprocating movement of the slider 308 are stopped, and when the coil spring 102 in the tube 310 decreases below the predetermined number, the rotation is resumed. Can be activated.
[0052]
Next, the operation of the present embodiment will be described.
[0053]
In the coil spring supply device 100 having the above configuration, a large amount of the coil spring 102 is put into the container 104 in a state where the container 104 is removed from the pair of rollers 202A and 202B. In a state where a large amount of the coil spring 102 is accommodated in the container 104, the container 104 is placed on the roller 202 so that the opening of the container 104 is in contact with the fixed disk 306. Thereby, the coil spring supply apparatus 100 will be in a startable state.
[0054]
When the coil spring supply device 100 is activated, the container 104 is rotated around the central axis by the driving unit 200 via the roller 202. Along with the rotation of the container 104, the coil spring 102 is wound up by the blades 106 installed on the inner surface of the container 104, and falls from the upper part in the container 104. Here, when the entangled coil spring 102 is wound around the blade 106 and falls from the upper part in the container 104, the entanglement is easily eliminated by the impact of the drop.
[0055]
A part of the coil spring 102 dropped from the upper part in the container 104 is inserted into a groove 304 provided in the chute 302.
[0056]
Since the chute 302 is inclined downward toward the outside of the container 104, the coil spring 102 inserted into the groove 304 slides along the groove 304 in the longitudinal direction of the coil spring 102 due to gravity and is discharged out of the container 104.
[0057]
Further, the coil spring 102 discharged to the outside of the container 104 passes through the tube 310 and is stopped by the stop unit 312 and waits for removal from the stop unit 312 in the assembly process downstream of the coil spring supply device 100.
[0058]
In this way, as the container 104 rotates, the coil spring 102 falls on the chute 302 without interruption and is inserted into the groove 304 one after another, so that the coil spring 102 is discharged out of the container one after another and placed in series in the tube 310. Aligned. Therefore, the coil spring 102 can be continuously supplied.
[0059]
Here, in the coil spring supply device 100 according to the present embodiment, since the container 104 is inclined so that the side on which the extraction unit 300 is installed is lowered, the coil spring 102 in the container 104 is placed on the installation side of the extraction unit 300. Even when the coil springs 102 are concentrated and accumulated and the coil springs 102 in the container 104 are reduced, the coil springs 102 are gathered on the side of the take-out unit 300 at the bottom of the container 104. Therefore, the coil spring 102 wound and dropped by the blade 106 is also concentrated on the take-out part 300 installation side, and many coil springs 102 are dropped on the chute 302, so that the probability that the coil spring 102 is inserted into the groove 304 increases. The coil spring 102 can be supplied stably. In addition, even when the coil spring 102 in the container 104 decreases as the coil spring 102 is supplied, the coil spring 102 can be supplied stably.
[0060]
Further, since the take-out portion 300 is installed to be shifted from the central axis of the container 104 to the downstream side in the rotation direction (left side in FIG. 2A), the horizontal portion in the left direction in FIG. Many coil springs 102 that fall with movement fall on the chute 302. Therefore, the probability that the coil spring 102 is inserted into the groove 304 is further increased, and the coil spring 102 can be supplied more stably.
[0061]
Further, since the guide portion 302A is installed on the central axis side of the container 104 from the groove 304 of the chute 302, the coil spring 102 supplied by dropping is not only directly inserted into the groove 304, but also on the guide portion 302A. The coil spring 102 that is dropped and supplied with the horizontal movement in the downstream direction of the rotation direction 104 is guided to the groove 304 by the guide portion 302 </ b> A, so that the coil spring 102 is easily inserted into the groove 304. Thereby, the coil spring 102 can be supplied rapidly. Further, since the chute 302 is inclined so that the guide portion 302A is higher than the groove 304, the guideability of the coil spring 102 to the groove 304 is improved. Further, even when the coil spring 102 that has fallen on the chute 302 bounces, the direction in which the coil spring 102 bounces is limited to the groove 304 side, and the coil spring 102 is more easily guided to the groove 304. Therefore, the coil spring 102 can be easily inserted into the groove 304, and the coil spring 102 can be supplied more quickly.
[0062]
Furthermore, since the wall height of the groove 304 on the side where the guide portion 302A is installed is lower than the wall height on the opposite side, the coil spring 102 guided on the groove 304 by the guide portion 302A is installed on the guide portion 302A. The coil spring 102 does not easily pass through the groove 304 by striking against the opposite wall (the higher wall), and is more easily inserted by the groove 304 (see FIG. 6C). Therefore, the coil spring 102 can be supplied more rapidly.
[0063]
On the other hand, when the entangled coil spring 102 is inserted into the groove 304, the dimension of the groove 304 is determined so that the entangled coil spring 102 protrudes from the groove 304. The slider 304 is always reciprocated on the groove 304 and is not discharged out of the container 104. Further, the entangled coil spring 102 is pushed out of the groove 304 as the slider 308 moves, and falls to the bottom of the container 104. Since the length of the slider 308 is determined so that one end of the slider 308 is always outside the container 104, there is no possibility that the coil spring 102 is sandwiched between the slider 308 and the fixed disk 306. . Therefore, even when the entangled coil spring 102 is inserted into the groove 304, clogging does not occur, and the coil spring supply device 100 does not stop.
[0064]
Here, when a pair of sensors 314 provided at predetermined positions outside the tube 310 detect that the coil spring 102 is in the tube 310, the motor 204 is stopped. When the pair of sensors 314 detects that there is no coil spring in the tube 310, the motor 204 is activated. Therefore, intermittent operation of the drive unit 200 is possible and continuous operation can be avoided, so that the durability of the coil spring supply device 100 is improved and the life is extended.
[0065]
In the above-described embodiment, the blade 106 has a flat plate shape. However, the blade 106 may be a curved surface, and the width of the blade 106 can be set to an arbitrary dimension. The number of blades 106 attached is eight, but the number of blades 106 is not limited, and may be six or ten, for example. Furthermore, although the blades 106 are installed over the entire length in the longitudinal direction of the container 104, they may be shorter than the entire length in the longitudinal direction of the container 104. In this case, it is desirable that the position and length of the blade 106 be determined in accordance with the length of the chute 302 in the container 104. Furthermore, although the blade 106 is slightly inclined from the direction facing the central axis of the container 104 to the downstream side in the rotation direction of the container 104, the blade 106 may be directed to the central axis direction of the container 104 and is attached when it is inclined. The angle can be any angle.
[0066]
Further, in the above-described embodiment, a set of extraction units 300 is provided, but a plurality of extraction units 300 may be provided in parallel to each other.
[0067]
Furthermore, in the above embodiment, the sensor 314 is provided. However, the sensor 314 may not be provided. This configuration is cheaper and is effective when the coil spring 102 is quickly discharged from the stop portion 312 by an assembly process downstream of the coil spring supply device 100.
[0068]
Furthermore, in the above-described embodiment, the stop portion 312 is provided. However, the stop portion 312 may not be provided. This configuration is effective when the assembly process downstream of the coil spring supply device 100 is an automatic device and the coil spring 102 is supplied to a predetermined position provided in the automatic device.
[0069]
As described above, in the coil spring supply apparatus 100 according to the present embodiment, a large amount of the coil spring 102 that is easily entangled can be introduced and continuously supplied reliably. Furthermore, since air pressure is not used, it is possible to reduce the size and the cost of the apparatus and operation.
[0070]
The coil spring supply device 100 according to the present embodiment can be applied to parts other than the coil spring 102, and can be applied in a large amount as in the case of supplying the coil spring 102, and continuously and reliably. Can supply.
[0071]
【The invention's effect】
As described above, the coil spring supply apparatus according to the present invention has an excellent effect that it can continuously supply coil springs that are easily entangled, and can further reduce the size and capacity and reduce the apparatus and operating costs. .
