Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a motor winding recovery device, and more particularly to a motor winding recovery device that recovers a motor winding from one end of a motor winding wound in the longitudinal direction of a motor component by cutting means.
[0002]
[Prior art]
  Conventionally, in disposal processing of mechanical devices such as a refrigerator and an air conditioner, a compressor is first taken out from a refrigerator main body. And after the refrigerant | coolant and refrigerating machine oil were extracted, the taken-out compressor is crushed as a whole by the means of freezing crushing and shredder crushing irrespective of the internal structure.
[0003]
  However, in the crushing process as described above, it is difficult to recover high-quality valuables. This is because once the crushing treatment is performed, it becomes difficult to separate and collect materials such as iron, copper, and aluminum, and the collection cost becomes extremely high.
  On the other hand, it is conceivable that the casing of the mechanical device is cut by a cutting means such as a gas burner or a lathe and the internal parts made of iron, copper, aluminum, etc. are manually disassembled and separated. However, the appropriate cutting position corresponding to the internal structure of the casing differs depending on each mechanical device. Therefore, the man-hours and costs required for disassembly separation are very large. In particular, it is difficult to efficiently perform the work of separating and collecting the motor windings of a motor (mechanical device) having a high material value from motor components such as a stator.
[0004]
  The applicant of the present application has proposed a motor winding recovery device in Japanese Patent Application No. 10-308308. In this apparatus, the end of an annular motor winding is gripped by a claw member, and the motor winding is pulled out from a motor component.
[0005]
[Problems to be solved by the invention]
  In the device described in the above-mentioned application, the claw member is inserted inside the motor winding and then expanded outward to be locked to the end of the motor winding. Then, the motor winding is pulled out with the end of the motor winding hooked by the claw member.
  However, when such a method is used, the motor winding may be deformed by the expansion of the claw member, and the end of the motor winding may not be gripped well.
[0006]
  In addition, the motor winding usually includes an outer peripheral coil and an inner peripheral coil whose end is located closer to the inner periphery than the outer coil, but these are integrated by binding with a thread or the like. It is often done. Therefore, if the motor winding is not gripped and pulled out, there may be a problem that the outer peripheral coil and the inner peripheral coil of the motor winding are separated and one of them remains without being pulled out.
[0007]
  SUMMARY OF THE INVENTION An object of the present invention is to suppress a malfunction at the time of pulling in a motor winding recovery device that grips and pulls out an end portion of a motor winding so as to be surely gripped.

This device 40 is a device for extracting a motor winding made of a copper material from a motor in a compressor disassembled and separated from a refrigerator and from which oil has been extracted. Before the drawing process by the device 40, there is a cutting process (see the cutting process of Japanese Patent Application No. 10-308308). In this cutting process, one end of the motor winding 10 wound around the stator 9 is cut. . The device 40 is a device that pulls out the motor winding 10 with one end cut off from the stator 9.
[0023]
  <Target of device>
  Before describing the device 40, the configuration of the motor winding 10 that is pulled out of the stator 9 of the motor by the device 40 will be described.
  The motor winding 10 is wound in the longitudinal direction of the stator 9 (vertical direction in FIG. 4). As shown in FIGS. 4 to 6, three types of coils 11, 12, and 13 are provided in the circumferential direction. They are lined up one by one. When the motor winding 10 is sent to the device 40, one end (the lower end in FIGS. 4 and 11) is cut by cutting means such as a lathe. Therefore, in this state, each coil 11, 12, 13 has an inverted U shape.
[0024]
  The three types of coils of the motor winding 10 are deformed flat at the other end (upper part in FIG. 4), and overlapped with other coils and bound by a thread or the like. From this overlapping state, as shown in FIGS. 4 to 6, the three types of coils can be named as an outer coil 11, an intermediate coil 12, and an inner coil 13. The other end portion 11 a of the outer coil 11 overlaps the other end portion 12 a of the intermediate coil 12 and the other end portion 13 a of the inner coil 13 in a plan view, but the outer periphery is more outer than the other end portion 12 a of the intermediate coil 12. It is located near. The other end portion 12a of the intermediate coil 12 is positioned closer to the outer periphery than the other end portion 13a while overlapping with the other end portion 13a of the inner peripheral coil 13.
[0025]
  <Device configuration>
  A motor winding and pulling device 40 shown in FIG. 1 mainly includes a frame 41, a gripping mechanism 50, a cart 61 that supports the gripping mechanism 50, and a power cylinder 60 that moves the cart 61.
  (flame)
  The frame 41 includes a horizontal frame 41a and a vertical frame 41b. The horizontal frame 41a spans the upper ends of the left and right vertical frames 41b (only one is shown in FIG. 1) and supports the power cylinder 60. A guide plate 42 shown in FIGS. 1 and 2 is fixed to the vertical frame 41b extending in the vertical direction. The guide plate 42 serves to limit the moving direction of the carriage 61 to the vertical direction. A work fixing member 17 for fixing the stator 9 including the motor winding 10 and the casing 8 (work) around the stator 9 extends laterally from the lower part of the vertical frame 41b.
[0026]
  (Grip mechanism)
  The gripping mechanism 50 is a mechanism for gripping the other end (upper part) of the motor winding 10 included in the stator 9 fixed by the work fixing member 17, and is connected to the other end of the motor winding 10 from the inner peripheral side. An inner peripheral support member 51 that hits and an outer peripheral pressing mechanism 52 that hits the other end of the motor winding 10 from the outer peripheral side.
[0027]
  The inner peripheral support member 51 is a columnar boss that is fixed to the carriage 61 via the member 57. The inner peripheral support member 51 is detachably screwed to the member 57 and can be replaced in accordance with the diameter of the motor winding 10. The outer diameter of the tip large diameter portion 51 b of the inner peripheral support member 51 is substantially equal to the inner diameter of the other end portion of the motor winding 10. Further, a tip small diameter portion 51a having an outer diameter substantially equal to the inner diameter of the stator 9 is formed at the tip of the tip large diameter portion 51b (see FIG. 9).
[0028]
  As shown in FIG. 3A, four sets of outer peripheral pressing mechanisms 52 are provided at equal intervals in the circumferential direction. The outer peripheral pressing mechanism 52 includes a claw 53, an arm 54, a link member 55, and an air cylinder 56. Yes. The claw 53 is fixed to one end of the arm 54. The other end of the arm 54 is pin-supported by a member 57 fixed to the carriage 61. The link member 55 connects the lower end of the rod of the air cylinder 56 and the intermediate portion of the arm 54 with a pin. The air cylinders 56 are fixed to the carriage 61, respectively. When the rod is pushed down by the operation of the air cylinder 56, the arm 54 rotates about the fulcrum P as a rotation center, and the claw 53 turns to move to the inner peripheral side (see FIGS. 9 and 10).
[0029]
  The claw 53 has a root portion 53 b fixed to the tip of the arm 54, and extends inward from the tip of the arm 54. As shown in FIG. 3, the tip 53a of the claw 53 applied to the motor winding 10 is thinner than the root 53b. Specifically, the thickness of the tip portion 53a of the claw 53 is set to a value that is half or less of the root portion 53b.
[0030]
  Further, the claw 53 is designed so that some play is generated in the direction indicated by the white arrow A1 in FIG. 7, that is, in the circumferential direction. Specifically, play is provided at each pin support portion of the arm 54 and the link member 55 so that the claw 53 plays in the circumferential direction.
  Further, as shown in FIGS. 3 and 10, the cross-sectional shape of the bottom portion 53 c of the claw 53 is an arc shape centered on a fulcrum P that is the turning center of the arm 54.
[0031]
  As shown in FIG. 7, the planar shape of the claw 53 has a width larger than the sectional shape of the coil. In detail, the width | variety of the front-end | tip of the nail | claw 53 is set to the dimension which can hit three coils.
  As shown in FIG. 2, the carriage 61 includes four sets of wheels 61 a that sandwich the guide plate 42 from the left and right, and can move in the vertical direction along the guide plate 42 within a predetermined range. The lower end of a rod 60 a that moves up and down by the operation of the power cylinder 60 is fixed to the carriage 61. A member 57 that supports the inner peripheral support member 51 and the arm 54 and four air cylinders 56 of the outer peripheral pressing mechanism 52 are fixed to the lower surface of the carriage 61.
[0032]
  <Operation of the device>
  Next, the operation of the device 40 will be described.
  When one end of the motor winding 10 wound around the stator 9 of the compressor that has been disassembled and separated from the refrigerator and has been oiled is cut, the workpiece is opposite to the one end cut as shown in FIG. It is set on the work fixing member 17 of the apparatus 40 with the other end portion located on the upper side. At this time, the operator confirms the position of the outer peripheral side coil 11 that can be easily grasped when viewed from the outside, and sets the work on the apparatus 40 so that the claws 53 that can hit the three coils do not hit the outer peripheral side coil 11 To do. In other words, the operator sets the workpiece so that the claw 53 hits three of the four coils between the outer peripheral side coils 11. Thereby, for example, the workpiece is set at a circumferential position as shown in FIG. Here, each claw 53 is set so as to hit two inner peripheral side coils 13 and one intermediate coil 12, but if each claw 53 hits at least one inner peripheral side coil 13, all the motor windings 10 are set. Therefore, the workpiece may be set so that each claw 53 contacts one inner coil 13 and two intermediate coils 12.
[0033]
  In this simple apparatus 40, the work is set by the operator. However, as described above, the work is automatically set by using a sensor or a rotating device so that the circumferential position of the coil is matched. It is desirable to add a mechanism to be made.
  When the work is set on the work fixing member 17, the power cylinder 60 is driven to lower the gripping mechanism 50 to the position shown in FIG. This position is a position where the tip portion 53a of the claw 53 hits a portion directly below the other end of the motor winding 10 when the arm 54 is turned (see FIG. 8). At this time, the tip large-diameter portion 51b of the inner peripheral support member 51 abuts on the other end portion of the motor winding 10 and the inner peripheral end immediately below the other end portion (see FIGS. 7 to 9).
[0034]
  Next, the air cylinder 56 is operated, and the tip of the claw 53 is applied to the motor winding 10 from the outer peripheral side by turning the arm 54 and the claw 53 (see FIG. 10). In addition, the dashed-dotted line in FIG. 10 is the state of the nail | claw 53 before the air cylinder 56 action | operation. As a result, the portion directly below the other end of the motor winding 10 is sandwiched between the inner peripheral support member 51 on the inner peripheral side and the four claws 53 on the outer peripheral side. Since the claw 53 is urged to the inner peripheral side by the force of the air cylinder 56, the portion directly below the other end of the motor winding 10 is mainly pressed by the pressing force of the claw 53 from the side of the inner peripheral support member 51. It will be in the state pressed against the front-end | tip large diameter part 51b.
[0035]
  In this state, the carriage 61 and the gripping mechanism 50 are lifted upward by driving the power cylinder 60. As a result, the motor winding 10 having the other end (the other end 13a of the inner peripheral coil 13 and the other end 12a of the intermediate coil 12) gripped by the gripping mechanism 50 moves upward. Since it is fixed to the fixing member 17, the motor winding 10 is pulled out from the stator 9.
[0036]
  <Features of the device>
  (1)
  In the apparatus 40 of the present embodiment, the gripping operation is performed by the inner peripheral support member 51 that abuts on the inner peripheral end of the motor winding 10 and the outer peripheral pressing mechanism 52 having the claw 53 that contacts the motor winding 10 from the outside. ing. For this reason, even if the claw 53 hits from the outside of the motor winding 10, the motor winding 10 hardly deforms because the inner peripheral support member 51 exists. Therefore, the other end portion of the motor winding 10 is securely gripped, and troubles at the time of extraction are reduced as compared with the conventional case.
[0037]
  In the present embodiment, gripping is performed by pinching the other end of the motor winding 10 between the inner peripheral support member 51 and the claw 53 mainly by a lateral pressing force by the claw 53. It is also possible to hold the motor winding 10 by hooking 53 to the other end of the motor winding 10.
  (2)
  In the apparatus 40 of the present embodiment, a plurality of coils arranged in the circumferential direction are separated at the other end into an outer peripheral side and an inner peripheral side, and the motor winding 10 that avoids interference with each other is reliably extracted from the stator 9. In addition, each claw 53 hits at least one inner peripheral coil 13. If the claw 53 hits only the outer coil 11, only the outer coil 11 may be pulled out and the intermediate coil 12 or the inner coil 13 may remain on the stator 9 side. If the inner peripheral side coil 13 is gripped by applying 53 to the inner peripheral side coil 13 from the outside, not only the inner peripheral side coil 13 but also the intermediate coil 12 and the outer peripheral side coil 11 can be pulled out together.
[0038]
  (3)
  The motor winding 10 including the outer peripheral coil 11, the intermediate coil 12, and the inner peripheral coil 13 can easily grasp the position of the outer peripheral coil 11 in appearance (see FIG. 4), but the intermediate coil 12. And the inner peripheral coil 13 are difficult to distinguish. It can be said that it is difficult even if it is a case of using a human hand or a case of using a sensor or the like. In view of this, in the present apparatus 40, the claw 53 hits three coils from which the outer peripheral side coil 11 of the motor winding 10 is removed in order to reliably apply the claw 53 to the inner peripheral side coil 13. . Specifically, the width of the tip of the claw 53 is set to a dimension that can hit three coils. As a result, as long as the outer peripheral side coil 11 is removed, the claw 53 reliably hits the inner peripheral side coil 13.
[0039]
  (4)
  In the apparatus 40 of this embodiment, the structure which the nail | claw 53 hits the motor winding 10 from the outer peripheral side is taken. However, it is likely that the workpiece sent to the device 40 often has a casing 8 covering the motor winding 10 wound around the stator 9 as shown in FIG. The casing 8 is cut in the previous step (cutting step). When the cutting remaining amount d (see FIG. 11) generated when the cutting position shifts from the end face of the stator 9 is large, the claw 53 is moved to the casing 8. There is a risk that the remaining portion 8a of the cut will interfere with the motor winding 10.
[0040]
  In view of such consideration, in the present apparatus 40, the shape of the bottom 53c of the claw 53 extending from the arm 54 is formed into an arc shape with the fulcrum P of the arm 54 as the center, so that interference between the claw 53 and the casing 8 is avoided. The strength of the nail 53 is ensured.
  Further, in view of the above consideration, in the present apparatus 40, the tip portion 53a of the claw 53 extending from the arm 54 is made thin, and the root portion 53b of the claw 53 connected to the arm 54 is made thick. For this reason, even when the casing 8 having a relatively large uncut portion 8a is present, the problem that the claw 53 is obstructed by the casing 8 and cannot be brought close to the motor winding 10 is suppressed (see FIG. 12).
[0041]
  12 is a part of the workpiece fixing member 17 and serves to prevent the workpiece casing 8 and the stator 9 from moving upward.
  On the other hand, if the entire nail 53 extending from the arm 54 is thin, a problem in strength occurs. Therefore, a structure in which the thickness of the nail 53 is continuously changed is adopted, and the root portion 53b of the nail 53 is thickened. (See FIG. 3B and the like).
[0042]
  (6)
  In the apparatus 40 of the present embodiment, since the pawl 53 is designed to play slightly in the circumferential direction, even when the positional accuracy of the pawl 53 with respect to the motor winding 10 is not so high, to the workpiece fixing member 17 as well. Even when the accuracy of setting the workpiece is not so high, the claw 53 reliably hits a desired coil of the motor winding 10.
[0043]
  [Other Embodiments]
  (A)
  In the above embodiment, the curved shape at the tip of the claw 53 is made gentle so that one claw 53 can hit three coils as shown in FIG. 7, but it only hits two coils as shown in FIG. It is also conceivable to employ a claw 153 having a tip width of. In this case, it is necessary to set the workpiece so that at least one of the two coils to which the claws 153 are applied becomes the inner peripheral coil 13.
[0044]
  Moreover, as shown in FIG. 14, it is also possible to employ a claw 253 having a tip width enough to hit one coil. The claw 253 has a smaller curvature of the curved shape at the tip than the claw 53 and the claw 153. In this case, it is necessary to set the work so that the claw 253 contacts the inner peripheral coil 13.
  Further, a claw 353 shown in FIG. 15 may be employed instead of the claw 153 shown in FIG. The tip of the claw 353 has a curved shape corresponding to each of the two coils.
[0045]
  In FIG. 7 and FIGS. 13 to 15, the symbols “inner 1” and “outer 3” are attached to the coils. These are “first inner peripheral coil” and “third outer peripheral side”. It means content such as “coil”.
  (B)
  In the above-described embodiment, the example in which the motor winding 10 including the outer peripheral coil 11, the intermediate coil 12, and the inner peripheral coil 13 is extracted from the stator 9 has been described. However, the motor winding including the outer peripheral coil and the inner peripheral coil is described. Even when 10 is pulled out, a configuration in which the other end is sandwiched between the inner peripheral support member 51 and the claw 53 and a configuration in which the claw 53 is applied to the inner peripheral coil are effective.
[0046]
【The invention's effect】
  In the present invention, the gripping operation is performed by the inner peripheral support member that contacts the inner peripheral end of the motor winding and the contact member that contacts the motor winding from the outside. Even if it hits, the motor winding is hardly deformed, and the certainty of gripping the other end of the motor winding is improved.
[0047]
  Further, if the abutting member is applied to at least the inner peripheral coil, all the motor windings can be extracted from the motor components.
