Description

  The present invention relates to a parts unraveling apparatus and a supply apparatus using the same, which automatically unfolds intertwined parts such as a coil spring using a vibration type parts feeder.

  Of the vibratory parts feeder, the torsional vibratory part feeder with a bowl is used to efficiently loosen the entangled coil spring without causing clogging in the entanglement unraveling device, and to stabilize the coil spring without entanglement to the next process. A coil spring supply device that can be supplied is known (see, for example, Patent Document 1). A conventional coil spring supply device disclosed in Patent Document 1 is shown in FIG.

  In the coil spring supply device 200 of FIG. 4, the coil spring is transferred in a line in the longitudinal direction on the U-shaped track 203 having a U-shaped cross section following the flat plate track 202 b of the torsional vibration part feeder 202. The U-shaped track 203 is provided with a sorting gate 204 that can be opened and closed on the downstream side, and the coil spring that is not entangled is passed as it is and sent to the next process, but the entangled coil spring cannot pass through the sorting gate 204 and stops. . When the stopped coil spring is detected by the transfer stop detection sensor 205, the sorting gate 204 is opened, and air is ejected from the exhaust air ejection port 206 and dropped into the collection path 207 to be eliminated. The removed coil spring is untangled by the tangling device 208 connected to the collecting path 207 and returned to the bowl 202a.

  This cylindrical entanglement device 208 is disposed substantially horizontally at the downstream end of the collection path 207 and is fixed to the outer surface side of the peripheral wall of the bowl 202a. An introduction port 208 a for introducing the entangled coil springs collected in the collection path 207 is provided slightly below the center of the upstream end face plate of the entanglement device 208. A discharge port 208b is provided at the bottom of the downstream end face plate. Although not shown, a plurality of rectangular flat plates for causing the entangled coil springs to collide with each other are fixed to the upper part of the inner wall surface of the entanglement device 208 in the axial direction at a pitch slightly smaller than the length of the coil springs. Also, an air injection nozzle is inserted in the vicinity of the upstream side plate at the bottom of the inner wall surface, and the outlet of the air injection nozzle is arranged in a transfer direction so that the jet air becomes a helical flow along the inner wall surface. It is provided with a slight inclination.

  The downstream end face plate is easily attached and detached with screws, and the coil spring can be easily taken out even when the entanglement device 208 is entangled.

  Further, a return path 209 is connected to the discharge port 208b of the entanglement device 208 and communicates with the bottom surface of the bowl 202a through an opening formed in the peripheral wall of the bowl 202a. The level of the return path 209 is slightly higher, and the drop is equal to or less than the diameter of the coil spring.

JP-A-8-188229

The coil spring supply device 200 of FIG. 4 utilizes a general torsional vibration part feeder configuration, introduces a loosening device to loosen the entangled coil spring, transfers the coil spring, separates the entangled coil spring, and is aligned. In this way, it is supplied to the next process.

  Therefore, the coil spring supply device 200 needs to have a function of loosening the separated and separated parts, unlike the torsional vibration parts feeder that only supplies and supplies the conventional parts.

  Incidentally, the coil spring supply device 200 of FIG. 4 includes a selection gate 204 for selecting the entangled coil springs. Thereby, the entangled coil spring that has been transferred without being separated by the U-shaped track 203 can be captured. However, every time the entangled coil spring reaches the selection gate 204, the coil spring supply device 200 is forcibly stopped, and the transfer is not resumed unless a series of processes such as gate opening, air blowing, and gate closing are performed. That is, every time the entangled coil spring reaches the selection gate 204, the coil spring supply device 200 stops the supply, and the operating rate decreases.

  In order to prevent a significant decrease in the operating rate, it is necessary to keep the rate at which the entangled coil spring reaches the selection gate 204 low. Therefore, the U-shaped track 203 has to be designed at a certain long distance.

  Further, it is necessary to provide a collection path 207 for collecting the entangled coil springs that have fallen from the U-shaped track 203. If the U-shaped track 203 becomes longer, this collection path 207 must also be designed longer. In addition, when the entanglement device 208 for loosening the coil springs collected in the collection path 207 is arranged outside the bowl 202a, the size of the device is inevitably increased, and the degree of freedom of installation is lost and the cost increases. Invite.

  Furthermore, if the U-shaped track 203 is configured in parallel as in the configuration of FIG. 4 in order to suppress a reduction in operating rate, it is necessary to arrange the transfer stop detection sensor 205, the excluded air injection port 206, etc., respectively. Cost increase is remarkable.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a parts unraveling apparatus that can reduce costs and reduce the size of the apparatus, and that can prevent a reduction in operating rate, and a supply apparatus using the parts unraveling apparatus.

  In order to achieve the above-described object, the parts unraveling device of the present invention is entangled by rapidly stirring a coiled coil spring in a small container having a discontinuous inner surface whose momentum changes rapidly. Unravel. More specifically, a vibratory parts feeder that transports parts along a spiral track formed inside the side wall, and a parts introduction port and parts that are arranged in the vibratory parts feeder so as to resonate and the parts are introduced. A part discharge port through which air is discharged and an air supply port through which air is supplied are formed, and V-shaped in the circumferential direction in at least one place on the peripheral wall of the container that is erected substantially parallel to the upward direction of the spiral track A loosening container in which a V-shaped inner part with a continuous inner surface is formed on the mold, a parts introduction path that connects the upper end of the spiral track to the parts introduction port, and a part from the parts discharge port to the outside of the side wall of the vibratory feeder And a part lead-out path for guiding.

  In addition to the above configuration, the parts unraveling apparatus of the present invention is characterized in that the unraveling container is provided with a lid on which a part introduction port is formed at the top, and a parts discharge port is formed on the peripheral wall of the container.

  In addition to the above configuration, the parts unraveling apparatus of the present invention is characterized in that a protrusion protrudes from the bottom of the container immediately below the part introduction port.

  In addition to the above-described configuration, the parts unraveling device of the present invention is configured such that the air supply port is formed at a position where the supplied air can be swung along the inner side of the peripheral wall of the container, and the part discharge port is for the swirling air. It is characterized in that it is formed downstream of the V-shaped inner side with respect to the flow.

  In addition to the above-described configuration, the parts unraveling apparatus of the present invention is characterized in that 5 to 8 V-shaped inner portions are formed on the peripheral wall of the container.

  In addition to the above-described configuration, the parts unraveling device of the present invention has a narrow track width by notching a part of the inner diameter side so that the vicinity of the upper end of the spiral track opens to the bottom side of the vibration type parts feeder. It is formed so that it may become.

  Further, the supply device according to the present invention is the above-described parts unraveling device, which is connected to the downstream side of the part lead-out portion on the outside of the side wall, has an inclined surface in the width direction, and has a corner on the inclined lower side of the inclined surface. The apparatus further comprises an inclined transfer part having a part formed thereon.

  In addition to the above-described configuration, the supply device of the present invention has a narrow transfer unit that can sequentially transfer parts one by one in a predetermined direction on the downstream side of the inclined transfer unit. The upper inclined side excluding the portion is formed so as to open to the bottom side of the vibration type parts feeder.

  In addition to the above configuration, the supply device of the present invention has a tubular transfer path formed downstream of the narrow transfer section, and a branch pipe capable of supplying air toward the downstream side is formed in the tubular transfer path. It is characterized by that.

  As described above, according to the present invention, the entangled parts introduced into the loosening container move in the same direction as the spiral track turning by vibration and are disturbed by the supplied air. As a result, when the parts that are blown by the air and move at high speed in the loosening container pass through the V-shaped inner part formed on the inner surface, the direction changes suddenly and the entanglement is solved. Also, when moving under vibration, the entanglement is easily solved by the influence of vibration. Furthermore, since the loosening container is provided inside the vibrating parts feeder, the structure is simple and not bulky, and can be configured at low cost.

  Further, according to the present invention, since the part introduction port is formed in the upper part, the parts can be introduced into the unraveling container by the action of gravity without giving kinetic energy such as vibration. And since the upper part of the loosening container is closed with a lid, it is possible to prevent the parts from scattering and to smoothly discharge the parts from the parts discharge port by the pressure of air.

  In addition, according to the present invention, when a part is introduced from the part introduction port into the loosening container, a loosening action is generated by colliding with the protrusion, and it is possible to make the state easy to loosen. Furthermore, since a narrow path is formed between the protrusion and the container side wall, the speed of air flow increases, the number of collisions with the V-shaped inner side increases, and the change in the motion state also increases.

  In addition, according to the present invention, the V-shaped inner part and the part discharge port are arranged in the direction of the air flow swirling along the inside of the peripheral wall of the container, so that parts blown by air are discharged from the part discharge port. It will surely pass through the V-shaped inner part before being done. As a result, it is possible to change the movement state of the parts reliably and suddenly, making it easy to loosen, and smoothly discharging the parts from the parts discharge port formed on the air flow path. Clogging can be prevented.

  In addition, according to the present invention, 5 to 8 collisions with the V-shaped inner side can be expected per turn in the loosening container by air, so that the motion state changes a plurality of times and the efficiency of the loosening action is improved. improves.

  In addition, according to the present invention, parts that are greatly entangled in the same width as the width of the spiral track are separated before the part introduction path, so the size of the entangled parts introduced into the unraveling container is limited. Can be added. Thereby, the stable turning operation | movement by air can be maintained, without producing clogging in a loosening container.

  Further, according to the present invention, the parts discharged from the parts discharge port can be aligned along the wall on the enlarged diameter side.

  Further, according to the present invention, it is possible to smoothly accommodate one row of the parts aligned on the diameter-expanded side of the inclined portion into the narrow transfer portion, and to vibrate unnecessary parts whose alignment state is not constant. It can be returned to the bottom side of the parts feeder.

  Further, according to the present invention, since the force of air sent from the branch pipe can be efficiently applied to the parts, it is possible to prevent a reduction in operating rate.

It is a perspective view of the parts unraveling device concerning an embodiment of the invention. It is the partially broken view which looked at the wide transfer part which sends out the part discharged | emitted from the loosening container out of a bowl, and aligns it from the downstream. An example of parts that require a loosening process is shown, (a) shows a coil spring with a small diameter, (b) shows a coil spring with a large diameter, and (c) shows a C-shaped spring member. It is a top view of the conventional coil spring supply apparatus.

  Hereinafter, a part unraveling apparatus according to an embodiment of the present invention will be specifically described with reference to the drawings. However, the following description is a specific example of the present invention and does not limit the contents described in the claims.

  A parts supply apparatus 100 according to the present embodiment shown in FIG. 1 is configured based on a torsional vibration parts feeder 3 using a bowl 1.

  In the torsional vibration parts feeder 3, a plate spring 12 is inclined on a base 11, and the lower end side of the bowl 1 is connected to the upper end side of the plate spring 12. In FIG. 1, only one leaf spring 12 is shown, but it is provided at a plurality of locations so as to be inclined in the same direction along the circumferential direction of the bowl 1. Torsional vibration is generated in the bowl 1 with respect to the base 11 by AC driving an electromagnet (not shown) disposed in proximity to the leaf springs 12. Due to this vibration, the parts put into the bowl 1 are sent upward (in the direction of the arrow 32) along the spiral track 2 formed inside the side wall 1a of the bowl 1.

  The track width B1 of the spiral track 2 is formed with a sufficient width so that an excessive amount can be supplied in consideration of the amount dropped off during the selection.

  In the torsional vibration parts feeder 3, a loosening container 4 formed in a hexagonal shape is disposed so as to be substantially concentric with the bowl 1 in a plan view. This loosening container 4 is attached via the leg part 20 so that the vibration of the bowl 1 can be transmitted.

  Here, the loosening container 4 will be described in detail.

  The loosening container 4 is provided with a lid 23 having a part receiving port 24 formed in the center. A part introduction path 5 extending from the upper end portion 2 a of the spiral track 2 is connected to the receiving port 24. A protrusion 26 is formed immediately below the receiving port 24 so as to protrude upward from the bottom surface of the loosening container 4. The receiving port 24 is covered with a lid 49 so that the side to which the introduction path 5 is connected is opened.

  The hexagonal side wall (container peripheral wall) of the loosening container 4 is erected so as to be substantially parallel to the rising direction of the spiral track 2 (the direction of the arrow 39). An air supply port 8 is formed for one of the six side walls, and the tip of the air supply nozzle 10 is inserted along the inner surface of the container peripheral wall 4b.

  A large opening 45 is formed on the side of the bowl 1, and a take-out rail 6 extending to the outside of the bowl 1 through the opening 45 is connected to the one surface where the air supply port 8 is formed. Yes. A lid 50 is provided in the vicinity of the loosening container 4 of the take-out rail 6.

  In the configuration of the present embodiment, the take-out rail 6 is formed as a single member up to the outside of the bowl 1, but the function differs between the inside and the outside via the side wall 1 a of the bowl 1. Therefore, each area will be described separately.

  A region where the parts are discharged from the delivery port 25 of the loosening container 4 and led to the vicinity of the side wall 1a is defined as a lead-out path 6a. Moreover, since the outer part of the side wall 1a has the inclined surface where the diameter-expansion direction fell among the structures of the taking-out rail 6, it calls the inclination transfer part 6b.

  The inclined transfer part 6 b extends to above the tray part 51 extending below the opening 45. And the inclination transfer part 6b is gradually expanded as it leaves | separates from the loosening container 4, and forms the wide transfer part 41 in the downstream. The narrow transfer part 42 is connected so as to be continuous with the side wall on the enlarged diameter side of the wide transfer part 41.

  The narrow transfer part 42 is formed in a width that allows only one row of parts to be transferred. A tubular transfer part 46 is formed on the downstream side of the narrow transfer part 42, and an air supply path 48 (branch pipe) is formed in the tubular transfer part 46.

  Next, the operation of the parts supply apparatus 100 configured as described above will be described.

  The input parts (not shown, the movements are indicated by arrows 32 to 38) before being subjected to the unraveling process are input into the bowl 1 and hardened at the bottom 1b. When the torsional vibration parts feeder 3 starts operating, vibration is transmitted to the bowl 1 and the spiral track 2 formed on the side wall 1a of the bowl 1 also vibrates. The parts of the bottom 1b begin to rise along the spiral track 2 while spreading due to vibration (arrow 32). As described above, the track width B1 of the spiral track 2 is formed with a width sufficient to transfer an excessive amount of parts in order to prevent a reduction in operating rate. However, if it is sent to the unraveling container 4 in this excess amount, clogging occurs, so it is necessary to reduce it to an appropriate amount on the way. In the present embodiment, a return port 27 is formed by notching the upper end portion 2 a of the spiral track 2. Thereby, an excessive amount of parts falls from the return port 27, is returned to the bottom 1b of the bowl 1, and an appropriate amount of parts that have passed through the track width B2 can be sent to the loosening container 4.

In the configuration shown in FIG. 1, the example in which the region having the track width B2 is formed in the vicinity of the upper end portion 2a of the spiral track 2 is shown, but this causes the entangled parts to fall from the highest position. Therefore, the unraveling effect is higher than when dropping from another midway position. However, if the parts collide with each other, a new entanglement may occur. Then, it is preferable that a protrusion or a plate material for causing the parts to bounce so as not to stop is provided immediately below the return port 27.

  The parts that have not fallen from the return port 27 and have passed through the region of the track width B2 slide down through the introduction path 5 and are introduced into the loosening container 4 from the receiving port 24 (arrow 33). At this time, since the protrusion 26 is formed immediately below the receiving port 24, a part of the entangled parts is separated by the collision with the protrusion 26.

  In the loosening container 4, air 7 supplied from the air supply nozzle 10 flows in a direction along the inner surface of the container peripheral wall 4 b. Thereby, the parts introduced into the loosening container 4 are swung along the container peripheral wall 4b.

  In the present embodiment, since the protrusion 26 is formed at the center position of the loosening container 4, a narrow path is formed in a donut shape, and the flow rate of the air 7 is increased. Further, since the container peripheral wall 4b is formed in a hexagonal shape, six V-shaped inner portions 4c are formed. As a result, the intertwined parts turning at high speed are repelled on the inner surface of the container peripheral wall 4b each time they pass through the V-shaped inner part 4c, and the motion state changes greatly. In this way, the repeatedly intertwined parts are loosened by repeating the collision in which the motion state greatly changes.

  As described above, collision between parts may form a new entanglement state, but since the rectifying effect is increased by forming the protrusion 26, the probability that the parts collide with each other is reduced. It is possible. That is, it is possible to prevent the parts that collide with the V-shaped inner part 4c and bounce back and the subsequent parts from interfering with each other.

  Further, in the loosening container 4, it is possible to cause a plurality of collisions in a short time against the inner surface of the container peripheral wall 4 b by a turning motion based on the pressure of the air 7. The air 7 can be discharged at high speed. Thus, since the processing in the loosening container 4 is performed in a short time, it is not necessary to set the capacity large and the bowl 1 need not be expanded.

  In addition, the loosening container 4 is arranged concentrically with the bowl 1, and is connected to the bowl 1 by a leg 20 so that vibration is transmitted from the bowl 1. Thereby, apart from the action of the air 7, a loosening action by vibration and a transfer action can be expected.

  As can be seen from FIG. 1, a delivery port 25 is also formed on the surface where the air supply port 8 into which the air supply nozzle 10 is inserted is formed. That is, the delivery port 25 is formed on the downstream side of the flow of air 7 with respect to the air supply port 8, and passes through several V-shaped inner portions 4 c before reaching the delivery port 25 from the air supply port 8. Will do.

  Therefore, when the inside of the loosening container 4 is circulated, there is an opportunity for the exercise state to change greatly about several times per lap. In this way, the parts guided from the unwinding container 4 to the take-out rail 6 through the delivery port 25 are discharged in a substantially unraveled state. Accordingly, the number of entangled coil springs can be reduced, and the operating rate can be increased.

  Here, with reference to FIG. 2 which showed the cross-sectional view of the inclination conveyance part 6b formed outside the side wall 1a among the taking-out rail 6, the alignment effect | action of the discharged | emitted parts is demonstrated.

As described above, the take-out rail 6 is composed of the lead-out path 6a to the side wall 1a of the bowl 1 and the inclined transfer part 6b outside the side wall 1a. However, when the take-out rail 6 moves from the lead-out path 6a to the tilt transfer part 6b. Since the transfer path is inclined toward the diameter expansion side, as shown in FIG. 2, the loosened parts gather at the corner 6d on the diameter expansion side. Thereby, parts are aligned along the line of the corner 6d. With reference to FIG. 1, the corner 6d is connected to a narrow transfer portion 42 formed to have a width capable of feeding parts one by one. It is sent into the narrow transfer section 42. As described above, in this embodiment, the alignment transfer unit 43 including the region from the wide transfer unit 41 where the corner 6d is formed to the narrow transfer unit 42 connected to the corner 6d performs the loosening process. Later parts are aligned.

  This configuration is compared with a conventional parts feeder. In the conventional parts feeder, the movement is performed only by the force obtained based on the vibrations from the part input position to the most downstream position as the supply position. However, in the present embodiment, since the air 7 is supplied into the unraveling container 4, the parts after the unraveling process can be discharged from the delivery port 25 by the air pressure. That is, since it is sent out while maintaining the turning kinetic energy, it can be sent out at a higher speed than the movement by vibration.

  In general, in parts feeders, emphasis is placed on how high the operating rate can be maintained, but the parts unraveling device according to the present invention is based on air pressure even when trouble such as clogging occurs. Since the high-speed movement route (lead-out route 6a) is provided, the time until return can be shortened.

  The parts aligned in a line by the alignment transfer unit 43 move to the tubular transfer unit 46 connected downstream. A branch pipe 48 is formed in the tubular transfer portion 46 at the upper side. The branch pipe 48 is provided to supply the air 7 into the tubular transfer section 46, and can prevent or eliminate clogging of parts. Moreover, if the tubular transfer part 46 is comprised with a flexible member, even if a transfer path is bent suddenly, it can extrude with an air pressure, Therefore It becomes possible to change a supply direction freely.

  On the other hand, the parts arranged on the inner diameter side with respect to the parts arranged along the corner 6d fall from the opening 45 into the tray part 51 connected to the bottom 1b of the bowl 1, and are guided to the spiral track 2 again.

  By the way, in said embodiment, although the take-out rail 6 showed the example comprised by integral formation with the derivation | leading-out path 6a and the inclination transfer part 6b, it is not restricted to this, The derivation | leading-out path 6a and inclination of another member are shown. The take-out rail 6 may be configured by connecting the transfer unit 6b.

  FIG. 3 shows an example of a part that is easily entangled. FIG. 3A shows a coil spring 21 having a relatively small pitch and a small diameter. FIG. 3B shows a coil spring 21 having a large pitch and diameter. FIG. 3C shows a C-shaped spring member 22 such as a spring washer.

  As described above, when the take-out rail 6 is configured by a combination of the lead-out path 6a and the inclined transfer portion 6b, which are separate members, an appropriate inclination angle θ (see FIG. 3) for parts having different shapes as shown in FIG. 2), the inclined transfer part 6b can be selected, and the versatility of the parts supply apparatus 100 is improved.

  As described above, according to the parts unraveling apparatus (vibrating parts feeder) and the parts supply apparatus 100 using the parts unnecessarily, there is no need to provide a sensor for detecting the entanglement state. In addition, since the vibration type parts feeder is almost the same size and can be configured simply and compactly, the number of parts can be reduced, the cost can be reduced, and the degree of installation freedom can be improved.

  Furthermore, it is not necessary to separately provide an air spraying device or a sensor for returning the entangled parts separated by dropping in the middle to the loosening device or the bowl, so that power consumption can be suppressed.

  In the above embodiment, the example has been shown in which the loosening container 4 is formed in a hexagonal shape in plan view. However, the number of corners (V-shaped inner part 4c) is not limited to six in this way, and if at least one is formed, it is possible to obtain a loosening effect based on a sudden change in the motion state. It is. Actually, it is preferable that 5 to 8 corners are formed.

  Further, in the above embodiment, the configuration in which the protrusion 26 is formed so as to protrude upward from the bottom portion in the loosening container 4 is shown as an example. However, the protrusion 26 may not be formed. Absent. Further, it is not necessary to protrude from the bottom of the loosening container 4. Furthermore, it does not need to be formed in the center.

  In the above embodiment, the delivery port 25 is shown as an example of the structure formed on the most downstream side of the flow of the swirling air 7 with respect to the air supply port 8, but it is formed in the middle flow area. It doesn't matter.

  In the above embodiment, the configuration in which the return port 27 is formed in the upper end portion 2a of the spiral track 2 is shown as an example. However, the return port 27 may not be formed.

  In the above embodiment, the inclined surface of the inclined transfer portion 6b is shown as an example of a configuration that is inclined so as to be lowered in the diameter expansion direction. Further, it may be inclined so as to be lowered toward the inner diameter side, and the position of the corner 6d is not limited to the enlarged diameter side.

  The parts unraveling device of the present invention and the supply device using the same perform the unraveling process by changing the motion state by causing the parts to collide with each other. Therefore, the part unraveling device has a curved portion such as a coil spring and a spring washer. This is effective for easily shaped parts.
