Description

  The present invention relates to a separation device for separating and transferring a coiled member such as a coil spring that is easily entangled.

  A separating device is used to unwind the coil springs supplied to the assembly line or the like and to facilitate the assembly work. As a conventional technique, the spring separation device of Patent Document 1 is provided with a nozzle that blows compressed air in a blow-out passage that opens in the front and rear, and a blowout air and a spring in a separation chamber that is provided in communication with the opening on the outlet side. A separation plate provided with a large number of through holes for separation is disposed. The blow-out passage is formed in the vertical direction, and a U-shaped suction hose following the discharge port of the parts feeder is connected to the inlet side opening below the nozzle so that compressed air and a spring are ejected upward from the outlet side opening. Then, the spring is made to collide with the separation plate and separated.

  Further, in Patent Document 2, a housing provided with a collision surface portion for separating a spring, a spring passage provided at a bottom portion of the housing, aligning entangled springs in a traveling direction by vibration, and a bottom surface of the spring passage are provided. A spring separating device is disclosed that includes a spring collision means for causing an entangled spring flowing through a spring passage to collide with a collision surface portion. The spring collision means, for example, forms a compressed air blowout port on the bottom surface of the spring passage, blows up a spring passing through the blowout port, and collides with a collision surface portion directly above. Further, a compressed air supply port is provided on the entry side and the discharge side of the spring passage to adjust the feed rate of the spring.

JP-A-62-93119 Japanese Patent No. 3579521

  However, the apparatus described in Patent Document 1 requires a high-speed and large-volume suction conveyance device using compressed air as an operating source in order to form a strong air flow from the suction hose to the upper side of the blowout passage. As shown in FIG. 8, the suction conveyance device uses the inside of the pipe following the main body 101 as a part of the blowout passage, and supplies compressed air to the supply nozzle 102 connected to the side surface of the main body 101, thereby Create a discharge flow, perform vacuum suction, and carry parts. The supply nozzle 102 needs to be connected to an air compressor that generates compressed air as an operation source, and the air consumption, that is, the energy consumption increases, and the noise is also large.

  The device described in Patent Document 2 has the same problem as the device of Patent Document 1 in that it requires supply of compressed air. Further, since the compressed air supply ports are provided on the entry side and the discharge side in addition to the compressed air outlet, the air consumption increases. Moreover, in order to make it easier to separate the entangled spring, it is better to slow the flow of the spring toward the compressed air outlet on the entry side, and it is better for the spring to slowly pass directly above the compressed air outlet, which slows down the processing speed. . On the other hand, in order to discharge the accumulated spring on the discharge side, the flow of the spring is accelerated, and a mechanism for adjusting the feed rate of the spring on each of the entry side and the discharge side is required.

As described above, the conventional apparatus performs separation / conveyance using a large amount of compressed air, which consumes a large amount of energy and increases the apparatus cost and the operating cost. In recent years, reduction of CO ₂ emissions has been demanded as an environmental measure, but there is a problem that the amount of CO ₂ emissions increases as energy consumption increases.

  Therefore, the present invention can easily separate a coiled member such as a coil spring without using compressed air, and realizes a separation device that has a simple structure and good economic efficiency and environmental performance. For the purpose.

  Below, the separating apparatus 1 of the coil-shaped member used as 1st Embodiment of this invention is demonstrated in detail, referring drawings. FIG. 1 is a diagram showing an overall configuration of a separation apparatus 1 according to the present invention, and FIG. 2 shows a plan view and a side view thereof. The coil-shaped member targeted in the present invention is, for example, the coil spring S shown in FIG. 1B, and since the wire is wound in a spiral shape, entanglement and overlap are likely to occur. In addition, if the separation apparatus 1 of this invention is a coil-shaped member which has the same shape, it can be used suitably for all except a coil spring.

  In FIG. 1A, a separation device 1 includes a blower pipe 2 connected to a blower fan F, a charging pipe 3 for a coil spring S connected to the middle of the blower pipe 2, and a separation unit 41. 4. In addition, a supply unit 5 for supplying a coil spring to the charging pipe 3 is provided. The supply unit 5 includes a coil spring accommodating unit 51 placed on the table T, and a blower fan F is installed below the table T. The blower pipe 2 has one end side (lower end side in the figure) connected to the blower fan F and the other end side (upper end side in the figure) connected to the separation unit 4.

  The electric blower fan F rotates the fan by a motor connected to a power source (not shown), sucks back-side air, and blows it into the blower pipe 2 with a predetermined air volume. As shown in FIGS. 2B and 2C, the blower pipe 2 is connected to the blower fan F below the table T, passes through the table T in the vertical direction, and then curves in the horizontal direction. A horizontal portion 21 extending in parallel with the upper surface is formed. The blower pipe 2 is bent in the vertical direction again on the downstream side of the horizontal portion 21 to form a vertical portion 22 that extends upward toward the separation portion 4.

  The separation part 4 is a box-shaped body having a ceiling surface as a separation plate 41, and the vertical part 22 of the blower pipe 2 is connected to the center of the bottom surface 42. The separation plate 41 is constituted by a perforated plate having a large number of through holes on the plate surface for air escape, and thereby, an air flow rising up the vertical portion 22 can pass through the separation plate 41 and be discharged to the outside. ing. In the present invention, the coil spring S can be lifted by blowing air to collide with the separation plate 41 that moves up the vertical portion 22 together with the air flow, and the entangled coil spring S can be separated.

  The separation part 4 is integrally provided with a transport chute 43 that is open at one side and extends obliquely downward. Further, the bottom surface 42 of the separation unit 4 is an inclined surface that is inclined downward toward the conveyance chute 43. As a result, when the separated coil spring S falls, the coil spring S moves down from the inclined surface of the bottom surface 42 to the conveyance path 44 from the conveyance chute 43. The transport chute 43 and the transport path 44 form a transport path.

  In the present embodiment shown in FIG. 1, the input conduit 3 is arranged in the vertical direction (up and down direction in the figure) on the side of the cylindrical container-like coil spring accommodating portion 51. A closing port 52 for the coil spring S is attached to the opening on the proximal end side (upper end side in the drawing) of the closing line 3, and a part of the peripheral portion of the closing port 52 on the coil spring accommodating portion 51 side is excluded. There is a standing wall. Thus, the coil spring S accommodated in the coil spring accommodating portion 51 is guided from the inlet 52 to the proximal end side opening of the inlet pipe 3 and is formed so as to fall in the inlet pipe 3.

  As shown in FIGS. 2A to 2C, the insertion port 52 is provided so as to protrude from the upper edge of the coil spring accommodating portion 51 in the outer peripheral direction, and is located immediately above the proximal end portion of the insertion pipe line 3. . As the supply means, the supply unit 5 is provided with a bottom surface of the storage unit 51 in which the coil spring S is accommodated so that it can be moved up and down by the drive unit 53. The coil spring S can be supplied to the insertion port 52.

  The leading end side (lower end side in the figure) of the inlet pipe 3 extends vertically below the inlet 52 and is connected to the substantially central part of the horizontal part 21 of the blower pipe 2 from above. The cross-sectional structure of this connecting portion is shown in an enlarged manner in FIG. In the present invention, the leading end 31 of the charging pipe 3 is formed in a shape that penetrates the tube wall of the blower pipe 2 and protrudes into the horizontal portion 21 and that the leading end is inclined obliquely. Specifically, the opening surface of the tip is used as the confluence 32 of the coil spring, and the inclined surface is inclined with respect to the cross section orthogonal to the axis, and is arranged so as to face the downstream side of the air flow flowing through the horizontal portion 21 of the blower pipe 2. To do. The inclination angle α is preferably set as appropriate within a range of 10 degrees to 30 degrees. This numerical range will be described later.

  At this time, the pipe wall 33 forming the tip portion 31 has an inclined wall shape in which the protruding length becomes longer toward the upstream side of the flow in the horizontal portion 21. The pipe wall 33 surrounds the merging port 32 of the coil spring S and becomes a resistance against the air flow from the back surface, and a negative pressure is generated in the vicinity of the tip 31 so that the coil spring S can be sucked downstream from the merging port 32. And Thereby, the coil spring S thrown into the making pipe 3 can be joined to the flow in the blower pipe 2 and sent to the separation unit 4.

  Next, the operation of the separation device 1 of the present invention will be described with reference to FIG. When the blower fan F is energized in the separation device 1 shown in FIGS. 1 and 2, an air flow that passes through the horizontal portion 21 and flows from the vertical portion 22 toward the separation portion 4 is formed in the blower pipe 2. On the other hand, the supply part 5 of the coil spring S sequentially transfers the coil spring S accommodated to the inlet 52 on the outer periphery of the upper end as the bottom surface of the coil spring accommodating part 51 repeats the raising and lowering operation by the drive part 53. , And supplied to the input line 3.

  By this operation, the plurality of coil springs S are put together into the making line 3 and fall in the making line 3. Here, as shown to Fig.3 (a), in the structure which connected the vertical injection | throwing-in channel 3 to the pipe wall of the horizontal part 21 of the blast pipe 2, the strong flow (for example, 23 m / s) in the blast pipe 2 is carried out. It was found that the relatively small and light coil spring S was pushed up and blown back into the pipe (for example, 4.6 m / s). That is, in order to transfer the coil spring S to the separation part 3 together with the air flow, it is necessary to form a sufficiently strong wind flow in the blower pipe 2, but the connecting part 3 is simply connected to the connecting part 3. Therefore, the coil spring S stays and becomes clogged.

  Therefore, in the configuration of the present invention, as shown in FIG. 3 (b), the distal end portion 31 of the input pipe line 3 is formed into an obliquely cut shape and protrudes from the horizontal part 21 of the blower pipe 2 to the inside. The leading junction 32 is inclined, for example, by about 15 degrees and is arranged to face the downstream side of the flow. At this time, as shown in the drawing, the flow in the blower pipe 2 is detoured as indicated by an arrow by the duct wall 33 located on the back side of the junction 32, and a negative pressure is generated in the vicinity of the junction 32. Create suction power. Due to this ejector effect, the blowback phenomenon of the coil spring S is eliminated, and suction (for example, 3.7 m / s) occurs under the same wind speed conditions as in FIG. 3A, so that the clogging of the coil spring S is also eliminated.

  Specifically, as shown in FIG. 3C, if the inclination angle α of the junction 32 of the input pipe 3 is in the range of 10 degrees to 30 degrees, the suction force due to the ejector effect is similarly generated, and the coil The spring S can be sucked and conveyed. Further, the pipe diameter b of the input pipe 3 is preferably smaller than the pipe diameter a (for example, about φ60 mm) of the blower pipe 2 (for example, about φ40 mm). The leading end portion 31 of the input pipe 3 is preferably set to have a maximum projecting length c so as not to disturb the flow in the blower pipe 2 excessively, and is usually set shorter than the radius of the blower pipe 2 (for example, About 15 mm). By appropriately setting these relationships, it is possible to form an air flow having a relatively strong wind speed (for example, around 20 m / s) by only blowing by the blower fan F without using compressed air.

  The coil spring S sucked into the horizontal portion 21 of the blower pipe 2 moves up the vertical portion 22 by a sufficiently strong air flow and collides with the separation plate 41 of the separation portion 4. Thereby, even if it conveys with the some coil spring S being entangled, it can loosen an entanglement easily. The dropped coil spring S moves from the conveyance chute 43 to the conveyance path 44 along the bottom surface 42 of the separation unit 4. In this way, the coil spring S can be separated easily and effectively.

  FIG. 4 shows a second embodiment of the present invention, which differs from the first embodiment only in the connection structure of the input pipe line 3 connected to the horizontal portion 21 of the blower pipe 2. Other structures are the same as those in the first embodiment, and a description thereof will be omitted. In the present invention, as described above, the distal end portion 31 of the input conduit 3 protrudes into the horizontal portion 21, and the conduit wall 33 is an inclined wall shape whose protrusion length increases toward the upstream side of the air flow. Similar effects can be obtained. Therefore, the input pipe 3 does not necessarily need to be connected perpendicularly to the axis, and in this embodiment, the input pipe 3 itself is inclined as shown in FIG.

  Also in the present embodiment, the input pipe line 3 is connected to the horizontal portion 21 from above, but is inclined to the upstream side of the flow with respect to the direction perpendicular to the axis of the horizontal portion 21, and is connected to the junction 32. The leading end opening surface is directed to the downstream side of the flow. In the present embodiment, the front end opening surface of the input pipe line 3 is a surface orthogonal to the axis of the input pipe line 3 and is not an inclined surface. Thereby, the front-end | tip part 31 which protrudes in the horizontal part 21 of the blast pipe 2 becomes a shape which has the pipe line wall 33 which inclines to the upstream, and the ejector effect is formed in the vicinity of the junction 32 formed in the front-end opening surface. The suction force can be generated. The supply unit 5, the separation unit 4 and other configurations are the same as those in the first embodiment.

  Therefore, the coil spring S that is input from the supply unit 5 to the input port 52 is sucked from the junction port 32 to the horizontal unit 21 and is caused to collide with the separation plate 41 by the air flow toward the separation unit 4 through the vertical unit 22. Can do. Also in this case, it is preferable that the inclination angle α of the input pipe 3 with respect to the direction perpendicular to the axis of the horizontal portion 21 is set in a range of 10 degrees to 30 degrees. At this time, as in the first embodiment, the ejector effect is obtained by blowing air from the blower fan F. For example, when the flow of the wind in the blower pipe 2 is 23 m / s, the suction force near the junction 32 is set by setting the inclination angle α to 15 degrees as shown in the right figure of FIG. (For example, 3.7 m / s) is generated, and the coil spring S can be quickly sucked and conveyed.

  FIG. 4B is a graph showing the influence on the occurrence of blowback by changing the inclination angle and the pipe diameter when connecting the input pipe 3 to the horizontal portion 21 in the configuration of the second embodiment. is there. As shown in the figure, the pipe diameter b (φ60 to φ40) of the introduction pipe line 3 becomes smaller than the pipe diameter a (φ60) of the blower pipe 2 (φ60 to φ40), or the inclination angle of the horizontal portion 21 with respect to the axial direction increases. (0 degrees to 20 degrees), blowback is small. In particular, if the inclination angle is 10 degrees or more, negative pressure is generated in the vicinity of the tip 31 by setting the pipe diameter b of the inlet pipe line 3 to about ４０ of φ40 and the pipe diameter a of the blower pipe 2. Confirmed to do.

  Here, the left figure of FIG.4 (c) is a case where the front-end | tip part 31 is not protruded in the horizontal part 21 of the ventilation pipe 2 in the structure of 2nd Embodiment, and the inclination | tilt angle (alpha) of the injection | throwing-in pipe line 3 is 15. The suction force due to the ejector effect was 1 m / s. On the other hand, in the configuration of the present embodiment in which the distal end portion 31 is projected under the same conditions, the suction force is increased to 3.7 m / s as shown in the right diagram of FIG. In this way, the inlet pipe 3 is inclined and connected, and the tip 31 is formed into an inclined wall shape protruding into the blower pipe 2, thereby eliminating blowback and obtaining a sufficient suction force. .

  5 and 6 show a separation apparatus according to the third embodiment of the present invention, and the configurations of the supply unit 5 and the conveyance path are different. Other structures are the same as those in the first embodiment, and a description thereof will be omitted. In this embodiment, the coil spring accommodating part 51 of the supply part 5 is a rectangular parallelepiped container shape, and becomes a structure which moves the coil spring S to accommodate gradually by vibrating the container bottom face 54 with the vibration generator 55. FIG. Yes.

  On one end side (the left end side in the figure) of the coil spring accommodating part 51, an elevating part 6 is provided as supply means. As shown in FIGS. 6A and 6B, the upper surface 61 of the elevating unit 6 is a part of the bottom surface 54 and is an inclined surface that is inclined toward one end side (the left end side in the figure). It is configured to be movable up and down by a known lifting mechanism such as an air cylinder (not shown). The upper surface 61 is located on the side of the charging port 52 attached to the base end opening of the charging pipe 3 at the uppermost position, and has a function of supplying the coil spring S to the charging port 52. In the insertion port 52, a standing wall that surrounds the peripheral edge of the opening is formed except for a position facing the upper surface 61 of the elevating unit 6.

  The shape of the input pipe line 3 is the same as that of the first embodiment, and is connected in the vertical direction from above the horizontal part 21 of the blower pipe 2, and the tip part 31 projects into the horizontal part 21. The distal end portion 31 is inclined with respect to a surface perpendicular to the axis of the input pipe 3 at the distal end opening surface to become a confluence 32 that faces the downstream of the flow of the horizontal portion 21, and an inclined wall-shaped tube surrounding the upstream side thereof A road wall 33 is provided. Therefore, a negative pressure is generated in the vicinity of the merging port 32, and the coil spring S thrown into the feeding pipe line 3 by the suction force due to the ejector effect is sucked into the horizontal portion 21 from the merging port 32. And it can be made to introduce into the separation part 6 from the perpendicular | vertical part 22 with an air flow, the entangled coil spring S is made to collide with the separation plate 41, and can be isolate | separated.

  Further, in the present embodiment, the conveyance path 44 following the lower end opening of the conveyance chute 43 provided on the side of the separation unit 4 is linear and arranged along the upper edge of the long side of the coil spring accommodating portion 51. Therefore, after passing through the separation unit 4, the coil spring S that overlaps and entangles and protrudes from the conveyance path 44 while being aligned and conveyed from one end side to the other end side of the conveyance path 44 is transferred to the coil spring accommodating part 51. Can be dropped into the coil spring accommodating portion 51 by its own vibration and its own weight. The dropped coil spring S is supplied to the blower tube 2 again together with the coil spring S in the coil spring accommodating portion 51.

  With such a configuration, the coil spring S is more efficiently supplied to the separation unit 4 only by the air blow by the blower fan F, and the separated coil spring is transferred to the conveyance path including the conveyance chute 43 and the conveyance path 44. Then, it can be sent to the next process one by one.

As described above, according to the present invention, the coil spring S can be carried on the air flow of the blower pipe 2 without using compressed air. That is, as shown in FIGS. 7A and 7B, the air consumption (annual) can be reduced to zero, and noise can be reduced. Therefore, energy consumption can be greatly reduced, and an improvement in environmental performance can be expected by reducing CO ₂ emissions.

  In the above embodiment, the coiled member to be separated according to the present invention is the coil spring S, but the same effect can be obtained if the coiled member has a shape in which a wire is wound spirally. Furthermore, it is not limited to the coil-shaped member, and can be suitably used for separation of small parts having a shape that tends to cause entanglement and overlap.

  By adopting the separation device of the present invention, coiled members that are likely to be entangled or overlapped can be joined to the blower pipe without clogging, and can be easily transported to the separation unit and separated. Therefore, efficient parts supply is possible and it can be used for the manufacturing process of various products, and can contribute greatly to the improvement of productivity.
