DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor winding collecting apparatus, and more particularly to a motor for collecting a motor winding from one end of a motor winding wound in a longitudinal direction of a motor component cut by cutting means. The present invention relates to a winding collecting device.

[0002]

2. Description of the Related Art Conventionally, in the disposal of mechanical devices such as refrigerators and air conditioners, first, a compressor is taken out of a refrigerator body. After the refrigerant and the refrigerating machine oil have been extracted, the whole compressor is crushed as a whole by means of freezing crushing or shredder crushing, regardless of its internal structure.

[0003] However, in the above-mentioned crushing treatment, it is difficult to recover high-quality valuable resources. This is because once the crushing process is performed, it becomes difficult to separate and recover materials such as iron, copper, and aluminum, and the recovery cost becomes extremely high. On the other hand, the casing of the machine was cut by a cutting means such as a gas burner or lathe, and iron,
It is conceivable to manually disassemble and separate internal components made of copper, aluminum, or the like. However, depending on each machine,
Appropriate cutting positions corresponding to the internal structure of the casing are different. Therefore, the man-hour and cost required for disassembly and separation are extremely large. In particular, it is difficult to efficiently collect and separate the motor windings of a motor (mechanical device) having a high material value from motor components such as a stator.

Accordingly, the applicant of the present application has filed Japanese Patent Application No.
No. 8308 proposes an apparatus for collecting motor windings. In this device, an end of an annular motor winding is gripped by a claw member, and the motor winding is pulled out of a motor component.

[0005]

In the device described in the above-mentioned application, the pawl member is inserted outwardly of the motor winding and then expanded outward to be locked at the end of the motor winding. I do. The motor winding is pulled out with the claw member hooking the end of the motor winding. However, when such a method is used, the motor winding is deformed by the expansion of the claw member, and the end of the motor winding may not be grasped well.

[0006] The motor winding usually includes an outer coil and an inner coil whose end is located closer to the inner periphery than the outer coil. Are often integrated. Therefore,
If the motor winding is not properly grasped and pulled out, there is a possibility that the outer circumferential coil and the inner circumferential coil of the motor winding are separated and one of them remains without being pulled out.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a motor winding collecting device for holding and pulling out an end portion of a motor winding so as to surely hold the motor winding and to prevent a drawback at the time of drawing.

[0008]

According to a first aspect of the present invention, there is provided a motor winding collecting apparatus for recovering a motor winding from a motor winding wound in a longitudinal direction of a motor component and having one end cut by cutting means. , Comprising a gripping means and a driving means. The gripping means has an inner peripheral support member and a contact member, and grips the other end of the motor winding opposite to the one end cut by the cutting means. The inner peripheral support member contacts the inner peripheral end of the motor winding. The contact member is
It hits the motor winding from the outer circumference. The driving means moves the gripping means and pulls the motor winding from the motor component.

According to the present invention, there is provided an apparatus for extracting a motor winding from a motor winding, wherein one end of the motor winding is cut by a cutting means so that the remaining motor winding can be detached from a motor component. Device. Here, in a state where the other end of the motor winding is gripped by the gripping means, the driving means is operated to pull out the motor winding from the motor component. As a result, the motor windings and the motor components are separated, and valuable motor windings can be collected.

In the present apparatus, the gripping operation is performed by the inner peripheral support member abutting on the inner peripheral end of the motor winding and the abutting member contacting the motor winding from outside. For this reason, even if the contact member comes into contact with the outside of the motor winding, the motor winding is hardly deformed due to the presence of the inner peripheral support member.
Therefore, the reliability of gripping the other end of the motor winding is improved as compared with the related art.

The motor winding may be gripped by hooking the contact member to the other end of the motor winding, or the motor winding may be held between the inner peripheral support member and the contact member. The motor winding may be gripped. The motor winding collecting device according to claim 2 is the device according to claim 1, wherein the motor winding has an outer circumferential coil and an inner circumferential portion whose other end is closer to the inner circumferential side than the outer circumferential coil. And a side coil.
Then, the contact member is applied to the inner circumferential coil of the motor winding.

In this case, the motor winding has a plurality of coils arranged in the circumferential direction, and these coils are divided at the other end into an outer peripheral side and an inner peripheral side to avoid interference with each other. In order to reliably remove such a motor winding from the motor components, in the present apparatus, a contact member that contacts the motor winding from the outer peripheral side is applied to the inner peripheral coil. When the contact member contacts only the outer peripheral coil, there is a possibility that only the outer peripheral coil is gripped and pulled out and the inner peripheral coil remains, but as described above, the contact member is moved from the outer peripheral side to the inner peripheral side. If the inner peripheral side coil is gripped against the coil, not only the inner peripheral side coil but also the outer peripheral side coil can be pulled out together.

According to a third aspect of the present invention, there is provided the motor winding recovery apparatus according to the first aspect, wherein the motor winding is positioned such that the other end of the outer winding is closer to the inner circumference than the outer winding. And an inner peripheral coil whose other end is located closer to the inner periphery than the intermediate coil. The contact member is applied to at least the inner circumferential coil of the motor winding.

In this case, the motor winding has a plurality of coils arranged in the circumferential direction, and these coils are divided into an outer peripheral side, an inner peripheral side, and an intermediate part thereof (intermediate side) at their ends, and interfere with each other. Have been around. In order to reliably remove such a motor winding from a motor component, in the present apparatus, a contact member that contacts the motor winding from the outer peripheral side is applied to at least the inner peripheral coil. When the contact member does not contact the inner peripheral side coil but only the intermediate coil or the outer peripheral side coil, only the outer peripheral side coil or the intermediate coil may be gripped and pulled out and the inner peripheral side coil may remain, but If the contact member is applied to the inner peripheral coil from the outer peripheral side to grip at least the inner peripheral coil as described above, not only the inner peripheral coil but also the intermediate coil and the outer peripheral coil will be pulled out together. .

The contact member may be wide so as to be able to hold a plurality of coils, or has a tip width of one coil so as to hold only one coil (inner coil). It may be adjusted to the width. A motor winding collecting apparatus according to a fourth aspect is the apparatus according to the third aspect, wherein the contact member is applied to a plurality of coils other than the outer peripheral coil of the motor winding.

In the motor winding including the outer peripheral side coil, the intermediate coil, and the inner peripheral side coil, the position of the outer peripheral side coil can be easily recognized in appearance, but the intermediate coil and the inner peripheral side coil are distinguished. It is difficult. In view of this, in this device, in order to apply the contact member to the inner peripheral coil, the contact member is applied to a plurality of coils from which the outer coil of the motor winding is removed. If the contact member is applied to one coil even if the outer coil is removed, it is not guaranteed that the inner coil will be reliably contacted. However, in this case, the contact member is attached to a plurality of coils after removing the outer coil. Therefore, the contact member can be reliably applied to the inner peripheral side coil.

For example, when two inner coils and two intermediate coils are arranged between the outer coils, if the contact member is set to have a width capable of gripping three coils, the outer coil is formed. When the contact member is removed and applied to the motor winding, the contact member always comes into contact with the inner peripheral side coil. Claim 5
The device according to any one of claims 1 to 4, wherein the contact member includes an arm and a claw. The arm is movable in a radial direction. The pawl extends inward from the arm and strikes the motor winding. The nail has a thin tip portion and a thick root portion connected to the arm.

The present device employs a configuration in which the contact member contacts the motor winding from the outer peripheral side. However, there may be a casing surrounding the motor windings wound around the motor components. This casing is cut in the previous process, but when the cutting position is near the other end of the motor winding, the abutting member applied to the motor winding is disturbed by the uncut portion of the casing and approaches the motor winding. There is a risk of disappearing. For this reason, the portion of the contact member that is close to the motor winding should be as thin as possible.

In consideration of such considerations, here, the contact member is constituted by an arm and a claw, and the tip of the claw extending from the arm contacts the motor winding. And
The tip of the nail is made thinner, and the base of the nail connected to the arm is made thicker. Because the tip of the claw is thinner in this way, even if there is a casing remaining around the motor windings and motor components, the problem that the claw is obstructed by the casing and cannot be brought close to the motor winding is suppressed. Can be

On the other hand, if the entire claw extending from the arm is thin, a problem in strength occurs. Therefore, a structure in which the thickness of the claw is changed is adopted, and the thickness of the base of the claw is increased. . The motor winding recovery device according to claim 6 is the device according to any one of claims 1 to 5,
The contact member has a claw that contacts the motor winding. The claw has play in the circumferential direction of the motor winding.

In this case, since the pawls are configured to play in the circumferential direction, even when the positional accuracy of the abutting member with respect to the motor winding is not so high, the claw of the abutting member can be securely connected to the motor winding. Can be used. A motor winding recovery device according to claim 7 is the device according to any one of claims 1 to 6, wherein the contact member includes an arm and a claw. The arm is pivotable about a fulcrum so as to approach inside. The pawl extends inward from the arm and strikes the motor winding. Further, the shape of the bottom of the claw is an arc shape centered on a fulcrum, which is the center of rotation of the arm.

The present device employs a configuration in which the contact member contacts the motor winding from the outer peripheral side. However, there may be a casing surrounding the motor windings wound around the motor components. This casing is cut in the previous process, but when the cutting position is near the other end of the motor winding, the abutting member applied to the motor winding is disturbed by the uncut portion of the casing and approaches the motor winding. There is a risk of disappearing.

In view of such considerations, here, the contact member is constituted by an arm and a claw, and the tip of the claw extending from the arm contacts the motor winding. And
The shape of the bottom of the claw is an arc shape centered on the fulcrum of the arm. For this reason, it is possible to ensure the maximum strength of the claws while avoiding interference between the claws and members such as the casing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a motor winding extracting device (motor winding collecting device) 40 according to one embodiment of the present invention. 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 is drained. A cutting step (see the cutting step in Japanese Patent Application No. 10-308308) is present before the drawing step by the device 40. In this cutting step, one end of the motor winding 10 wound on the stator 9 is cut. . The device 40 comprises a motor winding 10 having one end cut off.
From the stator 9.

<Object of Apparatus> Before describing the apparatus 40, the form of the motor winding 10 that is pulled out from the stator 9 of the motor by the apparatus 40 will be described. The motor winding 10 is wound in the longitudinal direction of the stator 9 (vertical direction in FIG. 4), and as shown in FIGS. 4 to 6, three types of coils 11, 12, and 13 Are lined up one by one. When the motor winding 10 is sent to the device 40, one end (FIGS. 4 and 11) is cut by a cutting means such as a lathe.
Is cut off. Therefore,
In this state, each of the coils 11, 12, 13 has an inverted U-shape.

The three types of coils of the motor winding 10 are as follows:
At the other end (upper part in FIG. 4), it is deformed flat and overlapped with another coil and bound by a thread or the like. From this overlapping state, as shown in FIGS.
The types of coils are an outer peripheral coil 11, an intermediate coil 12,
And the inner peripheral side coil 13. The other end 11a of the outer peripheral coil 11 overlaps the other end 12a of the intermediate coil 12 and the other end 13a of the inner peripheral coil 13 in a plane, but is more outer than the other end 12a of the intermediate coil 12. It is located closer. The other end 12a of the intermediate coil 12
Are located closer to the outer periphery than the other end 13a while overlapping with the other end 13a of the inner peripheral side coil 13.

<Structure of Apparatus> The motor winding extracting apparatus 40 shown in FIG. 1 mainly includes a frame 41, a gripping mechanism 50, a bogie 61 supporting the gripping mechanism 50, and a power cylinder 60 for moving the bogie 61. It is configured. (Frame) The frame 41 includes a horizontal frame 41a and a vertical frame 41b. The horizontal frame 41a is bridged over the upper ends of the left and right vertical frames 41b (only one is shown in FIG. 1), and supports the power cylinder 60.
The vertical frame 41b extending in the vertical direction has a structure shown in FIGS.
Are fixed. 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 a lower portion of the vertical frame 41b.

(Gripping 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. An inner peripheral support member 51 contacts the end from the inner peripheral side, and an outer peripheral pressing mechanism 52 contacts the other end of the motor winding 10 from the outer peripheral side.

The inner peripheral support member 51 is a columnar boss 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 according to the diameter of the motor winding 10. The outer diameter of the large-diameter portion 51b at the distal end of the inner peripheral support member 51 is substantially equal to the inner diameter of the other end of the motor winding 10. Further, a distal end small diameter portion 51a having an outer diameter substantially equal to the inner diameter of the stator 9 is formed at the further distal end of the distal end large diameter portion 51b (see FIG. 9).

As shown in FIG. 3A, four sets of outer peripheral pressing mechanisms 52 are provided at equal intervals in the circumferential direction.
, An arm 54, a link member 55, and an air cylinder 56. The claw 53 is fixed to one end of the arm 54. The other end of the arm 54 is supported by a pin 57 on a member 57 fixed to the carriage 61. The link member 55 connects a lower end of the rod of the air cylinder 56 and an intermediate portion of the arm 54 with a pin. The air cylinders 56 are fixed to the cart 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,
3 turns and moves inward (see FIGS. 9 and 10).

The claw 53 has a root portion 53b fixed to the tip of the arm 54 and extends inward from the tip of the arm 54. Tip portion 53 of claw 53 applied to motor winding 10
As shown in FIG. 3, a has a thickness smaller than the thickness of the root portion 53b. Specifically, the thickness of the tip portion 53a of the claw 53 is set to a value equal to or less than half the thickness of the base portion 53b.

The nail 53 is indicated by a white arrow A1 in FIG.
, That is, a slight play is produced 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. As shown in FIGS. 3 and 10, the bottom 53 c of the claw 53 has a circular cross-section centered on the fulcrum P, which is the center of rotation of the arm 54.

The planar shape of the nail 53 is as shown in FIG.
Its width is larger than the cross-sectional shape of the coil. Specifically, the width of the tip of the claw 53 is set to a dimension that can hit three coils. The cart 61 has four sets of wheels 61a sandwiching the guide plate 42 from the left and right as shown in FIG. 2, and can move in the vertical direction along the guide plate 42 in 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 supporting 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 a lower surface of the carriage 61.

<Operation of Apparatus> Next, the operation of the apparatus 40 will be described. When one end of the motor winding 10 wound around the stator 9 of the compressor from which the oil has been removed by being disassembled and separated from the refrigerator is cut, the work is placed on the opposite side of the cut end as shown in FIG. It is set on the work fixing member 17 of the device 40 with the other end positioned upward. At this time, the worker confirms the position of the outer peripheral side coil 11 that can be easily grasped from the outside, and then sets the work on the device 40 so that the claw 53 that can hit three coils does not hit the outer peripheral side coil 11. I do. In other words, the operator has three claws 5 among the four coils between the outer peripheral coils 11.
Set the work so that 3 hits. This allows
For example, a workpiece is set at a circumferential position as shown in FIG. Here, each of the claws 53 has two inner circumferential coils 13.
And one intermediate coil 12, but each claw 53 has at least one inner circumferential coil 13.
, Since the entire motor winding 10 is reliably pulled out of the stator 9, the work may be set such that each claw 53 hits one inner circumferential coil 13 and two intermediate coils 12.

In the simple apparatus 40, the work is set by the operator. However, as described above, the work is automatically set using a sensor or a rotating device so that the circumferential position of the coil is adjusted. It is desirable to add a mechanism in which the set is 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
Is turned, the tip 53a of the claw 53 is
0 is a position corresponding to a portion directly below the other end of the “0” (see FIG. 8). Further, at this time, the large-diameter portion 51b at the distal end of the inner peripheral support member 51 comes into contact with the other end of the motor winding 10 and the inner peripheral end immediately below the other end (see FIGS. 7 to 9).

Next, the air cylinder 56 is operated, and the tip of the claw 53 is brought into contact with the motor winding 10 from the outer peripheral side by turning the arm 54 and the claw 53 (see FIG. 10). The dashed line in FIG. 10 indicates the state of the claw 53 before the operation of the air cylinder 56. Thus, 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. Air cylinder 5
Because the claw 53 is urged inward by the force of 6,
The portion directly below the other end of the motor winding 10 is pressed against the large-diameter portion 51b of the inner peripheral support member 51 mainly by the pressing force of the claw 53 from the side.

In this state, the carriage 61 and the gripping mechanism 50 are lifted upward by driving the power cylinder 60. Thereby, the other end (the other end 13 a of the inner peripheral coil 13 and the other end 12
a) The gripped motor winding 10 moves upward,
Since the stator 9 is fixed to the work fixing member 17, the motor winding 10 is pulled out from the stator 9.

<Characteristics of Apparatus> (1) In the apparatus 40 of the present embodiment, the gripping operation is performed by the inner peripheral support member 51 contacting the inner peripheral end of the motor winding 10, and the claw contacting the motor winding 10 from outside. This is performed by an outer peripheral pressing mechanism 52 having 53. For this reason, even if the claw 53 hits from the outside of the motor winding 10, the inner peripheral support member 51
, The motor winding 10 hardly deforms. Therefore, the other end of the motor winding 10 is securely held, and the drawback at the time of pulling out is reduced as compared with the related art.

In this embodiment, the gripping is performed by clamping the other end of the motor winding 10 between the inner peripheral supporting member 51 and the claw 53 mainly by the pressing force of the claw 53 from the side. However, the motor winding 10 can be gripped by hooking the claw 53 on the other end of the motor winding 10. (2) In the device 40 according to the present embodiment, the plurality of coils arranged in the circumferential direction are divided into the outer peripheral side and the inner peripheral side at the other end so that the motor windings 10 which avoid interference with each other can be reliably fixed to the stator 9. Each claw 53 is configured to contact at least one inner circumferential coil 13 in order to remove the inner coil 13 from the inner coil 13. When the claw 53 contacts only the outer peripheral side coil 11, the outer peripheral side coil 1
1 is pulled out and the intermediate coil 12 and the inner peripheral coil 13 are removed.
May remain on the stator 9 side.
0, the inner coil 13 is gripped by applying the claw 53 to the inner coil 13 from the outside, so that not only the inner coil 13 but also the intermediate coil 12 and the outer coil 11 are gripped.
Will also be pulled out together.

(3) Outer peripheral coil 11, intermediate coil 1
2 and the motor winding 10 including the inner peripheral side coil 13, it is easy to visually recognize the position of the outer peripheral side coil 11 (see FIG. 4), but the intermediate coil 12 and the inner peripheral side coil 1
It is difficult to distinguish from 3. It can be said that it is similarly difficult whether the operation is performed manually or using a sensor or the like. In view of this, in the present device 40, in order to surely apply the claw 53 to the inner peripheral side coil 13,
The claw 53 contacts the three coils of the motor winding 10 from which the outer coil 11 has been removed. Specifically, nail 5
The width of the tip of No. 3 is set to a size capable of hitting the three coils. As a result, if only the outer peripheral coil 11 is removed, the claw 53 reliably contacts the inner peripheral coil 13.

(4) The device 40 of the present embodiment employs a configuration in which the claw 53 contacts the motor winding 10 from the outer peripheral side. However, the work sent to the device 40 is the one shown in FIG.
As shown in FIG. 1, it is likely that a casing 8 that covers the motor winding 10 wound around the stator 9 exists around the motor winding 10. This casing 8 is cut in a previous step (cutting step), and the cut position is the stator 9.
When the remaining cutting amount d (see FIG. 11) generated due to the displacement from the end face of the casing 8 is large, the claw 53 may be obstructed by the remaining cutting portion 8a of the casing 8 and may not be able to approach the motor winding 10.

In consideration of such considerations, in the present apparatus 40,
The shape of the bottom 53 c of the claw 53 extending from the arm 54 is formed in an arc shape centering on the fulcrum P of the arm 54, thereby ensuring the strength of the claw 53 while avoiding interference between the claw 53 and the casing 8. Further, in consideration of the above consideration, in the present device 40, the tip portion 53a of the claw 53 extending from the arm 54 is thinned so that the base portion 53 of the claw 53 connected to the arm 54 is formed.
b is made thick. For this reason, even when the casing 8 having the relatively large remaining cutting portion 8a exists, the claw 53
Can be prevented from being disturbed by the casing 8 and approaching the motor winding 10 (see FIG. 12).

The work contact plate 17a shown in FIG.
Is a part of the work fixing member 17 and serves to prevent the work from moving upward of the casing 8 and the stator 9. On the other hand, if the entire claw 53 extending from the arm 54 is thin, a problem in strength occurs. Therefore, a structure in which the thickness of the claw 53 is continuously changed is adopted, and
b is configured to have a large thickness (FIG. 3B).
Etc.).

(6) In the device 40 of the present embodiment, the claw 53
Are designed to play slightly in the circumferential direction. Therefore, even when the positional accuracy of the claw 53 with respect to the motor winding 10 is not so high, the accuracy of setting the work on the work fixing member 17 is not so high. Also in this case, the claw 53 surely hits a desired coil of the motor winding 10.

[Other Embodiments] (A) In the above embodiment, the curved shape of the tip of the claw 53 is made gentle so that one claw 53 can hit three coils as shown in FIG. 13, a claw 153 having a tip width sufficient to hit two coils as shown in FIG.
It is also conceivable to employ. In this case, the nail 153
It is necessary to set the work so that at least one of the two coils to be applied is the inner circumferential coil 13.

Further, as shown in FIG. 14, it is possible to employ a claw 253 having a tip width enough to hit one coil. The nail 253 is compared with the nail 53 or the nail 153,
The curvature of the curved shape at the tip is small. In this case, the nail 25
It is necessary to set the work so that 3 hits the inner circumferential coil 13. Further, instead of the claw 153 shown in FIG. 13, a claw 353 shown in FIG. 15 can be adopted. The tip of the claw 353 has a curved shape corresponding to each of the two coils.

In FIGS. 7 and 13 to 15, the symbols “inner 1” and “outer 3” are attached to the coils, which are the “first inner peripheral side coil” and the “third inner coil”. Outer periphery side coil ". (B) In the above embodiment, the motor winding 10 composed of the outer coil 11, the intermediate coil 12, and the inner coil 13
Has been described from the stator 9, but even when the motor winding 10 composed of the outer peripheral side coil and the inner peripheral side coil is pulled out, the other end portion is held by the inner peripheral supporting member 51 and the claw 53, or the like. The configuration in which the claw 53 is applied to the inner circumferential side coil is effective.

[0048]

According to the present invention, the gripping operation is performed by the inner peripheral support member abutting the inner peripheral end of the motor winding and the abutting member contacting the motor winding from the outside. Even if it hits from the outside of a winding, a motor winding hardly deforms, and the certainty of grasping the other end of a motor winding improves.

Further, if the contact member is applied to at least the inner circumferential coil, all the motor windings can be pulled out of the motor components.
