Description

The present disclosure relates to a solar panel dismantling device that dismantles a frame portion of a solar panel in a reusable state.

Photovoltaic power generation is used for power generation in general households and for commercial power generation by companies, and solar panels configured as large panels using a large number of solar cells using semiconductors have been put into practical use.
Since the solar panel is installed outdoors, it is designed and manufactured to withstand rainfall, snowfall, strong wind, etc., but it may be damaged by abnormal stormy weather.
In addition, deterioration due to seasonal temperature differences and sunlight (ultraviolet rays) progresses due to long-term use. For this reason, a typical solar panel has a lifespan of about 20 to 30 years.
With the spread of solar power generation, as mentioned above, the number of discarded solar panels, such as those damaged by stormy weather and those that have reached the end of their life, will increase. is considered.

A general solar panel is configured by arranging a large number of cells in a panel shape, and the outer peripheral portion of the panel is fixed using, for example, an aluminum frame member.
When the solar panel is dismantled so that it can be recycled, the work of removing the frame member from the outer peripheral portion of the panel is performed. There is a device that presses the frame member by moving the claw member with an actuator when removing the frame member (Patent Document 1).

When the claw member is brought into contact with the frame member, this device moves the solar cell module placed on the stage toward the frame separation means, and the claw member provided on the frame separation means moves the frame of the solar cell module. Bring the members into contact.
At this time, the position of the solar cell module in the longitudinal direction is detected by the position detection sensor, and the pressurized position is determined inwardly by a predetermined distance from the end of the solar cell module.
In addition, pressing positions are determined at the center position of the solar cell module in the lateral direction, and at each of these pressing positions, the claw member is moved outward in the orthogonal direction of the frame member to separate the frame member from the solar cell module. do.

The above-mentioned claw member protrudes at the tip portion thereof so as to reach the portion (base end portion of the frame member) of the frame member having a substantially hook-shaped cross section where the solar cell module is joined. It is formed in a substantially L shape.
The claw member has a tip portion formed shorter than the longitudinal direction of the frame member. In the above device, only the tip portions of the claw members are brought into contact with the frame member to apply pressure.
That is, the above-described device is configured to detach the frame member from the solar cell module by concentrating pressure on a narrow range (small portion) of the frame member with which the tips of the claw members abut.

The operations of the respective mechanism units and the like to be described below are operations according to the control by the above-described control unit and the like.

FIG. 5 is an explanatory diagram showing the operation of the pushing member 10 provided in the dismantling device 1 of FIG. This figure shows the solar panel 30 placed on the mounting portion 3 (not shown), and the solar panel 30 is brought closer to the frame removal mechanism portion 5 (not shown), and the surface of the solar panel 30 is moved. Each extruded member 10 is represented.
The solar panel 30 exemplified here has a rectangular panel surface formed by arranging a plurality of solar cells 33 vertically and horizontally in the figure. For example, a glass surface cover (not shown) is superimposed on the surface of the solar cells 33 arranged as described above to cover the surface of the solar panel 30 .
A solar panel 30 having a rectangular panel surface has two long-side frame members 31 and two short-side frame members 32 fixed to the outer peripheral portion, and the panel edge is surrounded by these frame members. there is

The long-side frame member 31 and the short-side frame member 32 are each formed in a straight line, and in the thickness direction of the solar panel 30, a surface cover (not shown), a solar battery cell 33, and a back sheet (not shown) are arranged in layers. ), etc., and attached and fixed to the solar panel 30 .
First, the solar panel 30 configured as described above is placed on the placement portion 3 . When a predetermined operation is performed on the operation unit 6, for example, the control unit controls the operation of the elevating mechanism unit 4 to move the mounting unit 3 on which the solar panel 30 is mounted to the frame disposed above. It is lifted toward the removal mechanism part 5 and lowered appropriately to reach a predetermined height (the height for positioning the solar panel 30, that is, the solar panel 30 placed on the mounting part 3). to a height that allows movement) and stop.

Next, the dismantling device 1 positions the solar panel 30 placed on the placing portion 3 .
For example, the control unit operates each short-side push-out mechanism unit 21 shown in FIG. 4, and in FIG. Let
At this time, in FIGS. 4 and 5, the two pushing members 10 arranged in the vertical direction are set as one set, and the two pushing members 10 arranged on the right side in the figure are moved rightward (one horizontal direction). Then, the two pushing members 10 arranged on the left side in the figure are moved leftward (another horizontal direction).
In other words, each pushing member 10 is moved to open in the left-right (horizontal) direction.
When the mounting position of the solar panel 30 is deviated from the predetermined position, each push-out member 10 abuts on one of the short-side frame members 32 due to the operation of each short-side push-out mechanism 21 described above. Along the longitudinal direction of the side frame member 31, the solar panel 30 is moved in one lateral direction or the other lateral direction.
After that, the control unit reverses the operation of each short-side push-out mechanism unit 21 to move each push-out member 10 in the left-right direction (horizontal direction) so as to close and move to a predetermined position (for example, a long-side frame member). 31) at a suitable distance from the longitudinal ends of 31).

After that, the control unit, for example, operates each long-side push-out mechanism unit 20 to move each push-out member 10 (by a predetermined distance) along the longitudinal direction of the short-side frame member 32 in FIG. .
At this time, in FIG. 4 and FIG. 5, two pushing members 10 arranged in the horizontal direction are set as one set, and the two pushing members 10 arranged on the upper side in the figure are moved upward (one vertical direction). Then, the two pushing members 10 arranged on the lower side in the figure are moved downward (in the other vertical direction).
In other words, each pushing member 10 is moved to open in the vertical (longitudinal) direction.
When the mounting position of the solar panel 30 is deviated from the predetermined position, each pushing member 10 comes into contact with one of the long side frame members 31 by the operation of each long side pushing mechanism unit 20 described above. The solar panel 30 is moved in one longitudinal direction or the other longitudinal direction along the longitudinal direction of the side frame member 32 to move (arrange) the solar panel 30 to a predetermined position.
When positioning the solar panel 30, etc., each of the short-side push-out mechanisms 21 and each of the long-side push-out mechanisms 20 uses a weaker force than when each frame member to be described later is removed. Move 10 and act to gently abut either frame member.

After positioning the solar panel 30 as described above, the dismantling apparatus 1 starts an operation for removing the short-side frame members 32 of the solar panel 30 .
The control unit controls the elevating mechanism unit 4 to, for example, raise the mounting unit 3 to the upper limit position, and the height for removing each frame member of the solar panel 30 (the short side frame member 32 as described later). (height at which each pushing member 10 can be brought into contact).
For example, the control unit controls each long-side push-out mechanism unit 20 shown in FIG. 4 and the like, and in FIG. Adjust the distance between the two pushing members 10 (side by side).
That is, for example, the two long side pushing mechanism parts 20 supported by the driving cylinder part 21a of FIG. Adjust so that it is placed in
Here, although the operation related to the drive cylinder portion 21a will be described, the two long side push-out mechanism portions 20 supported by the drive cylinder portion 21b and the long side push-out mechanism portions 20 are supported and fixed. The arrangement positions of the two push-out members 10 are similarly adjusted, and the operation of pushing out the short-side frame members 32, which will be described later, is performed.

By adjusting the arrangement position of each push-out member 10, each push-out member 10 faces the end portion side of the longitudinal center of the short-side frame member 32 fixed to the solar panel 30, respectively.
Specifically, the pushing members 10 supported by the driving cylinder portion 21a (moved by the long-side pushing mechanism portions 20) are arranged symmetrically about the center of the short-side frame member 32 in the longitudinal direction.
The projecting portion 12 of one pushing member 10 is, for example, near one end in the longitudinal direction of the short side frame member 32 (when pressure is applied by the short side pushing mechanism 21, the short side frame member 32 does not bend). position).
In addition, a part of the short-side facing portion 10b of one extrusion member 10 is located on the longitudinal center side of the short-side frame member 32 from the position where the protrusion 12 of the one extrusion member 10 contacts the short-side frame member 32. and faces a predetermined position on the end side of the short-side frame member 32 from the center in the longitudinal direction (a position where the short-side frame member 32 is not bent when pressed by the short-side push-out mechanism 21). placed in

The protrusion 12 of the other pushing member 10 arranged symmetrically with the one pushing member 10 is, for example, near the other end in the longitudinal direction of the short side frame member 32 (when pressed by the short side pushing mechanism 21 , a position where the short-side frame member 32 is not bent).
A portion of the short-side facing portion 10b of the other push-out member 10 is located on the longitudinal center side of the short-side frame member 32 with respect to the position where the protrusion 12 abuts on the short-side frame member 32, and It is arranged so as to face a predetermined position on the other end side of the member 32 with respect to the center in the longitudinal direction.
In other words, the protruding portions 12 of each extrusion member 10 are opposed to the ends of the short-side frame member 32 in the longitudinal direction, and the short-side facing portions 10b of the extrusion members 10 are aligned with the ends of the short-side frame member 32 in the longitudinal direction. facing a position away from the part toward the center in the longitudinal direction.
Specifically, for example, the projecting portion 12 faces each longitudinal end of the short-side frame member 32 or a position in the vicinity thereof, and a part of the short-side facing portion 10b extends along the length of the short-side frame member 32 . The pushing member 10 is arranged so as to face a position at or near one-third of the longitudinal length of the short-side frame member 32 from each end in the direction toward the center in the longitudinal direction.

That is, as described above, the push-out member 10 has the protrusion 12 (first protrusion) on the short-side facing portion 10b side of the corner formed by the long-side facing portion 10a and the short-side facing portion 10b. is provided.
A portion (first contact portion) of the short-side facing portion 10b of the pushing member 10 is separated from the protrusion 12 (first protrusion portion), and the protrusion 12 contacts the short-side frame member 32. It is a portion that can contact a predetermined position on the longitudinal center side of the short-side frame member 32 from the contact position and on the end side of the short-side frame member 32 from the longitudinal center of the short-side frame member 32 (this predetermined position and (provided in a portion that can be abutted).
It should be noted that both the projecting portion 12 and a portion of the short-side facing portion 10b can abut on respective positions where the short-side frame member 32 does not bend or the like when the short-side frame member 32 is pressed. separated as much as possible.

As described above, when the arrangement positions of the two push-out members 10 are set in the longitudinal direction of the short-side frame member 32, the control unit operates the drive cylinder unit 21a (short-side push-out mechanism unit 21) to operate the drive cylinder unit 21a (short-side pushing mechanism unit 21). are moved in the direction of arrow B in FIG. Frame member 32 is removed.
That is, the projections 12 of each of the extrusion members 10 are brought into contact with the ends of the short-side frame member 32 in the longitudinal direction, and the short-side facing portions 10b of the respective extrusion members 10 are moved in the longitudinal direction of the short-side frame member 32. The short-side frame member 32 is removed by contacting and pressing the short-side frame member 32 away from each end toward the center in the longitudinal direction.
Specifically, when the two extrusion members 10 are pressed against the short-side frame members 32 as described above, the projections 12 (first projection portions) provided on the respective extrusion members 10 first Member 32 abuts, for example, at or near each end.
Further, by continuing the operation of the drive cylinder portion 21a, a portion (first contact portion) of the short-side facing portion 10b of each push-out member 10 moves to a predetermined position of the short-side frame member 32 (contact portion of the projection portion 12). The contact position is the central side of the short-side frame member 32 in the longitudinal direction, and the position where the short-side frame member 32 does not bend or the like when pressure is applied. Specifically, a part of the short-side facing portion 10b of each extrusion member 10 is, for example, the longitudinal length of the short-side frame member 32 from each longitudinal end of the short-side frame member 32 toward the longitudinal center. , and presses the short-side frame member 32.

As described above, the projecting portion 12 and a portion of the short-side facing portion 10b do not come into contact with the short-side frame member 32 at different timings. Therefore, stress is generated at the center of the short-side frame member 32 in the longitudinal direction, for example, to bend the short-side frame member 32 with such a large curvature that bending deformation does not remain (bending does not occur).
That is, the extrusion member 10 shortens the protrusion 12 so as to generate a stress that causes the short-side frame member 32 to bend with a curvature that does not cause bending deformation (so that the timing of contact with the short-side frame member 32 is appropriately shifted). It protrudes from the side facing portion 10b.
Further, the extrusion member 10 is arranged such that a portion of the short-side facing portion 10b that contacts the short-side frame member 32 and the protrusion 12 are separated from each other by the short-side frame member 32 (longitudinal length, etc.) so that the above stress is generated. are spaced apart according to the

The control unit controls the operation of the driving cylinder portion 21a (driving cylinder portion 21b) and the like as described above, and presses the pushing member 10 against the short-side frame member 32 while generating the above-described bending stress. Remove the short-side frame member 32 from the optical panel 30 .
After that, the control unit controls the lifting mechanism unit 4 to lower the mounting unit 3 to a predetermined height.
Next, the control unit controls each short-side push-out mechanism unit 21 to move each push-out member 10 pushing out each short-side frame member 32 as described above to a predetermined position (for example, each short-side frame member 32 ) so that the space between the extruded members 10 is closed.
Specifically, each push-out member 10 that pushes the short-side frame member 32 out of the solar panel 30 is moved to a position above the solar panel 30 .

After that, the control unit starts the operation of removing the long-side frame member 31 .
Here, the removal operation of the long-side frame member 31 arranged on the upper side in FIG. 5 will be described. Further, the removal operation of the long-side frame member 31 arranged on the lower side (in FIG. 5), whose explanation is omitted, is performed by the long-side push-out mechanism section arranged on the lower side of the driving cylinder portion 21a (in FIG. 4). 20 and the long-side push-out mechanism 20 arranged below the drive cylinder portion 21b are performed in the same manner as the removal operation of the long-side frame member 31 arranged above in FIG.

The control unit controls the elevating mechanism unit 4 to, for example, raise the mounting unit 3 to the upper limit position, and the height at which each frame member of the solar panel 30 is removed (the long-side frame member 31, as described later) (height at which each pushing member 10 can be brought into contact).
Thereafter, the controller controls the short-side push-out mechanism 21 so that they are aligned in the horizontal direction in FIG. 4 or 5 (aligned along the longitudinal direction of the long-side frame member 31 in FIG. 5). The arrangement positions of the two pushing members 10 are adjusted.
That is, the push-out member 10 supported and fixed to the long-side push-out mechanism 20 supported by the drive cylinder portion 21a shown in FIG. The push-out member 10 supported and fixed to the long-side push-out mechanism 20 that is arranged and supported by the drive cylinder portion 21b is arranged at a position facing the part on the other end side of the long-side frame member 31 in the longitudinal direction. Adjust so that
At this time, the ejecting member 10 moved by the driving cylinder portion 21a and the ejecting member 10 moved by the driving cylinder portion 21b are arranged symmetrically about the longitudinal center of the long-side frame member 31. As shown in FIG.

As described above, by adjusting the arrangement position of each pushing member 10 by the short side pushing mechanism portion 21 (drive cylinder portion 21a and drive cylinder portion 21b), a part (first 2) is, for example, the vicinity of each end in the longitudinal direction of the long-side frame member 31 (position where the long-side frame member 31 is not bent when pressed by the long-side pushing mechanism 20). Oppose.
Further, the protrusion 11 (second protrusion portion) of each pushing member 10 is located on the longitudinal center side of the long-side frame member 31 from the position where the protrusion 11 of the pushing member 10 contacts the long-side frame member 31 . They are arranged so as to face predetermined positions on each end side of the longitudinal center of the long-side frame member 31 .

Specifically, for example, the pushing member 10 moved by the driving cylinder portion 21a has a portion of the long side facing portion 10a that faces, for example, the vicinity of one longitudinal end portion of the long side frame member 31, and the protrusion 11 , is arranged to face a predetermined position on the one end side of the longitudinal center of the long-side frame member 31 .
In addition, a portion of the long-side facing portion 10a of the push-out member 10 moved by the drive cylinder portion 21b faces, for example, the vicinity of the other longitudinal end portion of the long-side frame member 31, and the projecting portion 11 It is arranged so as to face a predetermined position on the other end side of the side frame member 31 with respect to the center in the longitudinal direction.
In other words, each extrusion member 10 is moved by the driving cylinder portion 21a and the driving cylinder portion 21b, and the projection portion 11 of each extrusion member 10 is moved near the longitudinal center of the long-side frame member 31 from the longitudinal center to the longitudinal direction. facing away from each other towards each end. In addition, the long-side facing portions 10a of the push-out members 10 are made to face positions away from the positions facing the protrusions 11 toward the longitudinal ends of the long-side frame members 31 .
Specifically, for example, the protruding portion 11 of each pushing member 10 extends from the longitudinal center of the long-side frame member 31 toward each longitudinal end portion of the long-side frame member 31 in the longitudinal direction. A portion of the long-side facing portion 10a faces one position or a position in the vicinity thereof, and a portion of the long-side facing portion 10a extends along the longitudinal length of the long-side frame member 31 from each longitudinal end of the long-side frame member 31 toward the longitudinal center. Each pushing member 10 is arranged so as to face a position of one-eighth of or in the vicinity thereof.

That is, a part (second contact portion) of the long-side facing portion 10a of the pushing member 10 is, as described above, the long side of the corner formed by the short-side facing portion 10b and the long-side facing portion 10a. This is the portion on the side of the opposing portion 10a (provided at this corner).
In addition, the protrusion 11 (second projecting portion) of the pushing member 10 is separated from a portion (second contact portion) of the long side facing portion 10a, and a portion of the long side facing portion 10a abuts. It is provided at a position that is closer to the longitudinal center of the long-side frame member 31 than the position and can abut on a predetermined position on the end side of the longer-side frame member 31 from the longitudinal center.
The projection 11 and a part of the long-side facing portion 10a can abut on respective positions where the long-side frame member 31 does not bend or the like when the long-side frame member 31 is pressed. separated as much as possible.

As described above, when the arrangement positions of the two push-out members 10 are set in the longitudinal direction of the long-side frame member 31, the control unit controls the long-side push-out mechanism unit 20 supported by the drive cylinder unit 21a and the drive unit 20a. The long-side push-out mechanism part 20 supported by the cylinder part 21b is operated, for example, in synchronization, and the two push-out members 10 (maintaining the gap) are moved in the direction of arrow C in FIG. The long-side frame members 31 are pressed at the same time, and further pressure is applied to remove the long-side frame members 31 from the solar panel 30 .
That is, the projections 11 of each pushing member 10 are brought into contact with positions near the center in the longitudinal direction of the long-side frame member 31 and away from the center in the longitudinal direction toward each end in the longitudinal direction. In addition, the long-side facing portions 10a of the respective push-out members 10 are brought into contact with positions away from the position where the protrusions 11 abut toward the longitudinal ends of the long-side frame members 31, and press is applied. Remove the frame member 31 .

Specifically, when the two extrusion members 10 are pressed against the long-side frame members 31 as described above, the projections 11 (second projection portions) provided on the respective extrusion members 10 first move toward the long-side frame members. It abuts on a predetermined position of the member 31 (a position where the long-side frame member 31 does not bend or the like when pressure is applied). In addition, by continuing the operation of each long-side push-out mechanism 20, a part (second abutting portion) of the long-side facing portion 10a of each push-out member 10 moves to the longitudinal center of the long-side frame member 31, for example. A pressure is applied to a position closer to each end than the contact.
Specifically, for example, the protruding portion 11 of each push member 10 extends from the longitudinal center of the long-side frame member 31 toward each of the longitudinal ends of the long-side frame member 31 so as to extend by 8/8 of the length of the long-side frame member 31 in the longitudinal direction. A part of the long-side opposing portion 10a of each push member 10 is in contact with one or a position near it, and the longitudinal direction of the long-side frame member 31 extends from each longitudinal end of the long-side frame member 31 toward the longitudinal center of the long-side frame member 31. A pressure is applied against a position at or near one-eighth of the directional length.
The position where the projection 11 presses the long-side frame member 31 is the middle of the interval (range) from the longitudinal center to the longitudinal end of the long-side frame member 31. Any distance from the intermediate portion to the vicinity of the center in the longitudinal direction is sufficient.

As described above, the projecting portion 11 and a portion of the long-side facing portion 10a are not aligned with the long-side frame member 31 in timing. Therefore, in the vicinity of the central portion (periphery of the central portion) of the long-side frame member 31, for example, stress is generated to bend the long-side frame member 31 with such a large curvature that bending deformation does not remain (bending does not occur).
That is, the extrusion member 10 shortens the protruding portion 11 so as to generate a stress that causes the long-side frame member 31 to bend with a curvature that does not cause bending deformation (so that the timing of contact with the long-side frame member 31 is appropriately shifted). It protrudes from the side facing portion 10b.
In addition, the push-out member 10 is arranged such that a portion (first contact portion) of the long-side facing portion 10a that contacts the long-side frame member 31 (first contact portion) and the projection portion 11 (second contact portion) are arranged so as to generate the stress described above. , are spaced apart by a distance corresponding to the long-side frame member 31 (longitudinal length, etc.).

The control unit controls the operation of each long-side push-out mechanism unit 20 and the like as described above, and presses the push-out member 10 against the long-side frame member 31 while generating the bending stress, thereby forming the solar panel 30. Remove the long-side frame member 31 from the .
After that, the control unit controls the long-side push-out mechanism unit 20 to move each push-out member 10 to a predetermined position (for example, to close the space between the push-out members 10 pushing out the long-side frame members 31). .
Further, the control unit controls the lifting mechanism unit 4 and the like to lower the mounting unit 3 after elapse of a predetermined time, separate the mounting unit 3 from the frame removing mechanism unit 5, and move the mounting unit 3 The solar panel 30 and the like can be removed (removed).

The dismantling device 1 described here is configured to dismantle the solar panel 30 having long sides and short sides. It is possible to remove without bending the frame member or the like by means of the device.
The dismantling device 1 described here is equipped with an air slide cylinder or the like and is configured to operate using compressed air. It is also possible to configure to operate or to operate using a hydraulic cylinder or the like.
