Description

  The present invention relates to an apparatus for changing a pitch between workpieces when a plurality of thin workpieces are juxtaposed in a stacked manner at a predetermined pitch.

  For example, when a thin workpiece such as a solar panel is transferred from one container to another, the pitch between the works arranged in a stack may be different for reasons of the production process.

  In such a case, conventionally, the containers are manually transferred to different pitch containers. However, such a response is very inefficient. In addition, for example, in a thin work such as a solar panel, there is a problem that the work is easily damaged when an unexpected external force is applied in an oblique direction.

  Further, when the transfer is performed by a robot, it is possible to prevent such an unexpected force from being applied. However, since the transfer is performed one by one, the efficiency cannot be increased.

  This invention is an apparatus which changes only a lamination | stacking pitch, maintaining the lamination | stacking state of the said workpiece | work. With regard to such an apparatus, a technique related to “pitch”, “adsorption”, and “variable” was investigated in the international patent classification “B65H 3/00”, but no significant information was found. Reference information is as follows.

It moves in the horizontal direction in conjunction with the movement of the direction.

  At the lower end of the through holes 13a, 13b, and 13c (collectively referred to as “through holes 13”), the distribution plate 23 is fixed integrally with the base plate 3 so as to be replaceable. A suction pad 25 as an operating member is attached to the lower end portion of the distribution plate 23 so as to be replaceable. A passage 26 is provided in the distribution plate 23, and a passage 27 is provided in the suction pad 25.

  The elastic packing 15 attached to the through hole 13 of the base plate 3, the passage 26 provided in the distribution plate 23, and the passage 27 provided in the suction pad 25 form a telescopic communication passage 28. The The communication path 28 communicates with a suction port 29 provided in the suction pad 25. In the case of the present embodiment, each of the through holes 13 has a first through hole 13a on the first to tenth workpiece 51, a second through hole 13b on the eleventh to twentieth workpiece 51, and a third. The through-holes 13c are configured to correspond to the 21st to 30th workpieces 51, respectively, and as shown by hatching in FIG. 8, the first communication passage 28a (FIG. 8A) and the second communication passage respectively. A passage 28b (FIG. 8B) and a third communication passage 28c (FIG. 8C) are formed.

  2 and 9, 32 is a guide rod that communicates with each of the leaf springs 9, 33 is a stopper provided on the pedestal 34 and abuts against the open ends of the group of base plates 3, and 35 is on the open end side of the push plate 41. The provided slide bush 36 is a pitch determining cylinder that determines the pitch between the workpieces 51. 40a is a first joint for the first to tenth workpieces 51, 40b is a second joint for the eleventh to twentieth workpieces 51, and 40c is for the twenty-first to thirtieth workpieces 51. This is the third joint.

It is connected to the third communication passage 28c for the 30th workpiece 51. The joints 40a, 40b, and 40c are connected to a vacuum source (not shown) and transmit driving power from the vacuum source to the communication paths 28a, 28b, and 28c. 3 and 4, 37 is a rotary actuator for driving the drive shaft 31, 38 is a coupling for transmitting the drive force of the rotary actuator 37 to the drive shaft 31, and 39 is provided at both ends of the drive shaft 31. , 41 is a push plate which can be moved forward and backward provided at the open end of the group of base plates 3, and 43 is a fixed reference plate provided at the base end of the group of base plates 3. In the figure, arrow A indicates the pressing direction of the pitch determining cylinder 36, and arrow B indicates the direction of the restoring force of the leaf spring 9.

  Next, based on FIG. 10, the laminate stored in the small container 52 in a stacked state at one pitch (for example, a small pitch) is changed to another pitch (for example, a large pitch) and stacked on the large container 53. The operation when storing in the state will be described. Note that the size of the small pitch portion 19 of the variable spacer 17 is set in advance to the pitch between the workpieces 51 accommodated in the small container 52, and the size of the large pitch portion 20 of the variable spacer 17 is the workpiece accommodated in the large container 53. A pitch between 51 is set.

  First, the pitch-determining cylinder 36 is extended, the base plate 3 is pressed toward the reference plate 43 by the push plate 41, and the pitch between the base plates 3 is set between the workpieces 51 stored in a stacked state in the small container 52 (FIG. 2 ( A) corresponding to the small pitch shown in FIG. 10B (FIG. 10A).

  Next, the movable suction portion 1 is vertically moved in the direction of arrow C shown in FIG. 10A and inserted into the small container 52 with a small pitch. Each base plate 3 of the movable suction unit 1 inserts each suction pad 25 between each work 51 and sucks each work 51 to each suction pad 25. Each suction pad 25 sucks the surface of the workpiece in the direction orthogonal to the stacking direction, that is, the front surface 51a (indicated by a one-dot chain line in FIG. 1) or the rear surface of the workpiece 51.

  In this suction, the inside of the communication passage 28 is depressurized by a vacuum source (not shown), and the workpieces 51 are sucked to the suction ports 29 of the suction pads 25. At this time, the decompression in the communication path 28 simultaneously operates the first communication path 28a, the second communication path 28b, and the third communication path 28c. Thereby, the setting to the movable adsorption | suction part 1 of the laminated body 50 accommodated in the small container 52 in the laminated state is completed.

  Next, the movable suction unit 1 is moved vertically in the opposite arrow C direction to remove the laminate 50 from the small container 52, and then the movable suction unit 1 is moved in the horizontal direction so that the pitch between the workpieces 51 differs between the movable suction units 1. Move to large container 53.

  During the movement to the large container 53, the pitch between the base plates 3 is changed to the large pitch shown in FIGS. This process is shown in FIGS. 10B and 10C.

  First, each base plate 3 is pressed toward the push plate 41 by the reaction force of the set leaf spring 9, so that the movable suction portion 1 extends to the open end. FIG. 10B shows this state.

  Next, the rotary actuator 37 is rotated. Then, each variable spacer 17 inserted through the rotary actuator 37 rotates and the large pitch portion 20 comes into contact with the base plate 3. FIG. 10C shows this state.

Then is extended pitch decided cylinder 36 is fixed to the large pitch d ₂ shown in FIG. 7 (C) a contact or pitch of each work 51 between each variable spacer 17 and the base plate 3. FIG. 10D shows this state.

  In this state, the movable suction portion 1 is vertically moved in the direction of arrow D shown in FIG. 10D, then suction of each suction pad 25 is released, and the work 51 is stored in a large container 53 with a large pitch while being stacked. (FIG. 10D). Also at the time of the suction release in this transfer, the decompression of the communication passage 28 is released simultaneously with the first communication passage 28a, the second communication passage 28b, and the third communication passage 28c.

  Next, after the movable suction portion 1 is vertically moved in the direction of the opposite arrow D shown in FIG. 10 (D), when the pitch determining cylinder 36 is reduced, each base plate 3 is caused by the reaction force of the plate spring 9 that is set. Since it is pressed to the push plate 41 side, the movable suction portion 1 extends to the open end. As a result, the fixing of the variable spacers 17 in contact with the base plates 3 is released. FIG. 10E shows this state.

  Next, the rotary actuator 37 is rotated. Then, each variable spacer 17 inserted through the rotary actuator 37 rotates and the small pitch portion 19 comes into contact with the base plate 3. FIG. 10 (F) shows this state.

  Next, the pitch determining cylinder 36 is extended, and the contact between each variable spacer 17 and each base plate 3, that is, the pitch of each workpiece 51 is fixed to the small pitch 21 shown in FIG. As a result, the initial state shown in FIG.

  When the number of workpieces stored in the container is large, the above steps are repeated until the transfer work is completed.

  The transfer from the container 53 set to the large pitch to the container 52 set to the small pitch is the same as described above. At this time, the process starts from the state shown in FIG. As shown in FIG. 10 (F), FIG. 10 (A), FIG. 10 (B), and FIG. 10 (C), the state returns to the state of FIG.

  The suction of each workpiece 51 by each suction pad 25 is performed by the elastic packing 15 that can be expanded and contracted in the through hole 13 of each base plate 3, and the above operation is performed through the communication path 28 configured thereby. Therefore, since the airtightness of the communication path 28 is ensured, the transfer of the group of stacked objects 50 can be performed while maintaining the stacked state of the workpieces 51. Therefore, the change which changed the pitch of the laminated body 50 can be performed smoothly rapidly.

  This point will be described in more detail. Each communication path 28 communicates with the suction port 29 of each suction pad 25 through the elastic packing 15, and the elastic packing 15 moves in the horizontal direction in conjunction with the movement of the base plate 3. The expansion / contraction width of each elastic packing 15 is very small for each individual, but if each elastic packing 15 does not move, the amount of movement of the elastic packing 15a adjacent to the reference plate 43 side is The amount of movement of the elastic packing 15n adjacent to the push plate 41 serving as the open end is large. For example, when the expansion / contraction width of each elastic packing 15 is 0.8 mm, and each elastic packing 15 is not moved, the movement amount of the elastic packing 15a is 0.8 mm, but the nth is 30 pieces. The movement amount of the elastic packing 15n at the time of eyes is a large movement amount of “0.8 mm × (30−1) = 23.2 mm”. Therefore, when the elastic packings 15 are not movable, the reduced-pressure vacuum of the communication path 28 having the elastic packing 15 away from the reference plate 43 side as a component breaks down, making it difficult to attract the work 51. Become. However, in the present invention, each elastic packing 15 is movable in the horizontal direction in conjunction with the movement of the base plate 3, so that the expansion / contraction width of this degree (0.8 mm) is absorbed by the elastic packing 15 that can be expanded and contracted. Therefore, the expansion / contraction width of the elastic packing 15a (shown in FIGS. 2A and 2C) and the expansion / contraction width of the elastic packing 15n (shown in FIGS. 2A and 2C) are 0. It is 8 mm, and the amount of movement does not change depending on the installation site of the elastic packing 15, and the airtightness of the communication path 28 is always guaranteed. In addition, the airtightness of the communication path 28 is not affected by the number of elastic packings 15.

  Next, according to the above-described embodiment, since a pair of suction pads 25 are provided on each base plate 3, for example, when the workpiece 51 is suctioned and held, the arrangement of the leaf springs 9 is bilaterally symmetrical and vertically with respect to the slide guide 11. It becomes symmetrical, and the arrangement of the variable spacers 17 is bilaterally symmetrical and easy to balance, so that the apparatus is mechanically more stable.

  Next, in the above-described embodiment, the 30 workpieces 51 can be transferred at a time while maintaining the stacked state of the workpieces as the laminate. Therefore, the transfer operation can be performed reliably and stably.

  In the above embodiment, since a group of workpieces 51 are processed for each group under the jurisdiction of the three communication paths 28, even if some abnormality occurs in the base plate 3 belonging to one group, for example, the first communication path 28a, The operation of the second communication path 28b and the third communication path 28c belonging to another group can be continued. Therefore, it is possible to improve the efficiency of the transfer work from this point. It is also possible to change the contents of the work for each group.

  The laminate pitch changing device according to the present invention is not limited to the above-described embodiment. For example, the support by the operation member may support each workpiece 51 not by suction by the suction pad 25 but by clamping by the clamping member 45 as shown in FIG. In the case of FIG. 11, the sandwiching member 45 is composed of a pair of movable claws 45 a and 45 b that are connected by a spring 45 c, and a passage 46 that communicates with the communication passage 28 is provided at the base end portion. The spring 45c is always biased to the open state. When the inside of the communication passage 28 is depressurized by a vacuum source and overcomes the urging force of the spring 45c, the movable claws 45a and 45b are "closed", and the movable claws 45a as shown by the one-dot chain lines in FIGS. 45b, the side surface 51b of the work 51 is clamped.

  Further, the operation members such as the suction pad 25 and the sandwiching member 45 do not necessarily require a pair, and may be one or more than two. The work support surface by the operation member is arbitrary. For example, as shown in FIG. 11, the work 51 may be sandwiched from the work surface in the direction along the stacking direction, that is, from both side faces 51b of the work.

  The number of communication paths 28 is arbitrary, and can be appropriately increased or decreased depending on the number of workpieces to be applied.

  In the case where a plurality of communication passages 28 are provided, the operation can be performed sequentially. This is advantageous, for example, when the capacity of the vacuum source is small.

  In the illustrated embodiment, the elastic packing 15 has a bellows shape. However, the elastic packing 15 is not limited to this, and for example, elastic rubber packing, O-ring, or the like can be used. In any case, it can be moved in conjunction with the movement of the base plate 3.

  The number of leaf springs 9 and the number of recesses 7 on which the leaf springs 9 are placed are also arbitrary, and can be appropriately increased or decreased depending on the set pitch dimension.

  The pitch portions formed on the circumferential surface of the variable spacer 17 can also be, for example, three large, medium, and small. For example, when the number of pitch portions is three, each pitch portion is provided every 120 °, and in the case where a plurality of pitch portions are installed, the installation site of the pitch portions is appropriately changed.

  Moreover, the installation ratio of the pitch portion is not necessarily divided equally. For example, when the pitch portions are large and small, the installation ratio of the large pitch portions can be 60%, and the installation ratio of the small pitch portions can be 40%. In the case of a large, medium and small pitch portion, the installation ratio of the large pitch portion may be 40%, the installation ratio of the medium pitch portion may be 35%, and the installation ratio of the small pitch portion may be 25%.

  The timing for changing the pitch between the base plates 3 is arbitrary. Although the workpiece 51 may be being transferred as in the illustrated embodiment, the vertical movement of the movable support portion to the large container 53 after the transfer is performed during the vertical movement of the movable support portion to the small container 52 before the transfer. Sometimes, the pitch between the base plates 3 may be changed.

  The moving direction of the movable support portion is arbitrary. Although the case where the movable support portion is moved in the horizontal direction has been described in the above embodiment, the movable support portion may be moved in the vertical direction or may be moved in an oblique direction.

  The stacking direction of the base plate 3 constituting the movable support portion is arbitrary.

  The shape of the base plate 3 is arbitrary.

  The material of each part is arbitrary, but the base plate 3, the variable spacer 17, and the leaf spring 9 are desirably made of highly durable materials such as metal materials. The elastic packing 15 is preferably made of a material having a large elastic force, such as a plastic material or a rubber material. The suction pad 25 is preferably made of a material having a lightness, workability, chemical resistance, and hardness lower than that of the workpiece, for example, an appropriate plastic material. The distribution plate 23 is preferably made of, for example, an appropriate plastic material or light metal material from the viewpoint of lightness and workability.

  Further, the driving power for working on the workpiece 51 may be not only a vacuum source but also a pressure source, for example.

  The laminate pitch changing device according to the present invention is used to change the pitch between workpieces when a plurality of thin workpieces are juxtaposed in a laminated manner at a predetermined pitch, for example, to transfer solar panels. Can do.

  The present invention relates to an apparatus for changing a pitch between workpieces when a plurality of thin workpieces are juxtaposed in a stacked manner at a predetermined pitch.

For example, thin transfer objects such as solar panels (hereinafter, referred to as "work") work if the change to move to another container from a container, for reasons of production processes, which are arranged placed in layers Sometimes the pitch between is different.

  In such a case, conventionally, the containers are manually transferred to different pitch containers. However, such a response is very inefficient. In addition, for example, in a thin work such as a solar panel, there is a problem that the work is easily damaged when an unexpected external force is applied in an oblique direction.

  Further, when the transfer is performed by a robot, it is possible to prevent such an unexpected force from being applied. However, since the transfer is performed one by one, the efficiency cannot be increased.

In the figure, arrow A indicates the pressing direction of the pitch determining cylinder 36, and arrow B indicates the direction of the restoring force of the leaf spring 9.

  Next, based on FIG. 10, the laminate stored in the small container 52 in a stacked state at one pitch (for example, a small pitch) is changed to another pitch (for example, a large pitch) and stacked on the large container 53. The operation when storing in the state will be described. Note that the size of the small pitch portion 19 of the variable spacer 17 is set in advance to the pitch between the workpieces 51 accommodated in the small container 52, and the size of the large pitch portion 20 of the variable spacer 17 is the workpiece accommodated in the large container 53. A pitch between 51 is set.

First, the pitch-determining cylinder 36 is extended, the base plate 3 is pressed toward the reference plate 43 by the push plate 41, and the pitch between the base plates 3 is set between the workpieces 51 accommodated in a stacked state in the small container 52 (FIG. 3 ( A) corresponding to the small pitch shown in FIG. 10B (FIG. 10A).

  Next, the movable suction portion 1 is vertically moved in the direction of arrow C shown in FIG. 10A and inserted into the small container 52 with a small pitch. Each base plate 3 of the movable suction unit 1 inserts each suction pad 25 between each work 51 and sucks each work 51 to each suction pad 25. Each suction pad 25 sucks the surface of the workpiece in the direction orthogonal to the stacking direction, that is, the front surface 51a (indicated by a one-dot chain line in FIG. 1) or the rear surface of the workpiece 51.

  In this suction, the inside of the communication passage 28 is depressurized by a vacuum source (not shown), and the workpieces 51 are sucked to the suction ports 29 of the suction pads 25. At this time, the decompression in the communication path 28 simultaneously operates the first communication path 28a, the second communication path 28b, and the third communication path 28c. Thereby, the setting to the movable adsorption | suction part 1 of the laminated body 50 accommodated in the small container 52 in the laminated state is completed.

  Next, the movable suction unit 1 is moved vertically in the opposite arrow C direction to remove the laminate 50 from the small container 52, and then the movable suction unit 1 is moved in the horizontal direction so that the pitch between the workpieces 51 differs between the movable suction units 1. Move to large container 53.

In this moving to large container 53, to change the pitch between the base plate 3 to the large pitch shown in FIG. 3 (C) (D). This process is shown in FIGS. 10B and 10C.

  First, each base plate 3 is pressed toward the push plate 41 by the reaction force of the set leaf spring 9, so that the movable suction portion 1 extends to the open end. FIG. 10B shows this state.

  Next, the rotary actuator 37 is rotated. Then, each variable spacer 17 inserted through the rotary actuator 37 rotates and the large pitch portion 20 comes into contact with the base plate 3. FIG. 10C shows this state.

Next, the pitch-determining cylinder 36 is extended, and the working surfaces of the variable spacers 17 that are in contact with the base plates 3 are fixed to a large pitch d ₂ shown in FIG. FIG. 10D shows this state.

  In this state, the movable suction portion 1 is vertically moved in the direction of arrow D shown in FIG. 10D, then suction of each suction pad 25 is released, and the work 51 is stored in a large container 53 with a large pitch while being stacked. (FIG. 10D). Also at the time of the suction release in this transfer, the decompression of the communication passage 28 is released simultaneously with the first communication passage 28a, the second communication passage 28b, and the third communication passage 28c.

  Next, after the movable suction portion 1 is vertically moved in the direction of the opposite arrow D shown in FIG. 10 (D), when the pitch determining cylinder 36 is reduced, each base plate 3 is caused by the reaction force of the plate spring 9 that is set. Since it is pressed to the push plate 41 side, the movable suction portion 1 extends to the open end. As a result, the fixing of the variable spacers 17 in contact with the base plates 3 is released. FIG. 10E shows this state.

  Next, the rotary actuator 37 is rotated. Then, each variable spacer 17 inserted through the rotary actuator 37 rotates and the small pitch portion 19 comes into contact with the base plate 3. FIG. 10 (F) shows this state.

Next, the pitch-determining cylinder 36 is extended, and the action surface of each variable spacer 17 in contact with each base plate 3 is fixed to a small pitch d ₁ shown in FIG. As a result, the initial state shown in FIG.

  When the number of workpieces stored in the container is large, the above steps are repeated until the transfer work is completed.

  The transfer from the container 53 set to the large pitch to the container 52 set to the small pitch is the same as described above. At this time, the process starts from the state shown in FIG. As shown in FIG. 10 (F), FIG. 10 (A), FIG. 10 (B), and FIG. 10 (C), the state returns to the state of FIG.

  The suction of each workpiece 51 by each suction pad 25 is performed by the elastic packing 15 that can be expanded and contracted in the through hole 13 of each base plate 3, and the above operation is performed through the communication path 28 configured thereby. Therefore, since the airtightness of the communication path 28 is ensured, the transfer of the group of stacked objects 50 can be performed while maintaining the stacked state of the workpieces 51. Therefore, the change which changed the pitch of the laminated body 50 can be performed smoothly rapidly.

This point will be described in more detail. Each communication path 28 communicates with the suction port 29 of each suction pad 25 through the elastic packing 15, and the elastic packing 15 moves in the horizontal direction in conjunction with the movement of the base plate 3. The expansion / contraction width of each elastic packing 15 is very small for each individual, but if each elastic packing 15 does not move, the amount of movement of the elastic packing 15a adjacent to the reference plate 43 side is The amount of movement of the elastic packing 15n adjacent to the push plate 41 serving as the open end is large. For example, when the expansion / contraction width of each elastic packing 15 is 0.8 mm, and each elastic packing 15 is not moved, the movement amount of the elastic packing 15a is 0.8 mm, but the nth is 30 pieces. The movement amount of the elastic packing 15n at the time of eyes is a large movement amount of “0.8 mm × (30−1) = 23.2 mm”. Therefore, when the elastic packings 15 are not movable, the reduced-pressure vacuum of the communication path 28 having the elastic packing 15 away from the reference plate 43 side as a component breaks down, making it difficult to attract the work 51. Become. However, in the present invention, each elastic packing 15 is movable in the horizontal direction in conjunction with the movement of the base plate 3, so that the expansion / contraction width of this degree (0.8 mm) is absorbed by the elastic packing 15 that can be expanded and contracted. Thus, in either case stretching the width of the elastic packing 15a (shown in FIG. 2 (A) (C)) ( shown in FIG. 2 (A) (shown in C)) stretch width or elastic packing 15n of 0. It is 8 mm, and the amount of movement does not change depending on the installation site of the elastic packing 15, and the airtightness of the communication path 28 is always guaranteed. In addition, the airtightness of the communication path 28 is not affected by the number of elastic packings 15.

  Next, according to the above-described embodiment, since a pair of suction pads 25 are provided on each base plate 3, for example, when the workpiece 51 is suctioned and held, the arrangement of the leaf springs 9 is bilaterally symmetrical and vertically with respect to the slide guide 11. It becomes symmetrical, and the arrangement of the variable spacers 17 is bilaterally symmetrical and easy to balance, so that the apparatus is mechanically more stable.

  Next, in the above-described embodiment, the 30 workpieces 51 can be transferred at a time while maintaining the stacked state of the workpieces as the laminate. Therefore, the transfer operation can be performed reliably and stably.

  In the above embodiment, since a group of workpieces 51 are processed for each group under the jurisdiction of the three communication paths 28, even if some abnormality occurs in the base plate 3 belonging to one group, for example, the first communication path 28a, The operation of the second communication path 28b and the third communication path 28c belonging to another group can be continued. Therefore, it is possible to improve the efficiency of the transfer work from this point. It is also possible to change the contents of the work for each group.

  The laminate pitch changing device according to the present invention is not limited to the above-described embodiment. For example, the support by the operation member may support each workpiece 51 not by suction by the suction pad 25 but by clamping by the clamping member 45 as shown in FIG. In the case of FIG. 11, the sandwiching member 45 is composed of a pair of movable claws 45 a and 45 b that are connected by a spring 45 c, and a passage 46 that communicates with the communication passage 28 is provided at the base end portion. The spring 45c is always biased to the open state. When the inside of the communication passage 28 is depressurized by a vacuum source and overcomes the urging force of the spring 45c, the movable claws 45a and 45b are "closed", and the movable claws 45a as shown by the one-dot chain lines in FIGS. 45b, the side surface 51b of the work 51 is clamped.

  Further, the operation members such as the suction pad 25 and the sandwiching member 45 do not necessarily require a pair, and may be one or more than two. The work support surface by the operation member is arbitrary. For example, as shown in FIG. 11, the work 51 may be sandwiched from the work surface in the direction along the stacking direction, that is, from both side faces 51b of the work.

  The number of communication paths 28 is arbitrary, and can be appropriately increased or decreased depending on the number of workpieces to be applied.

  In the case where a plurality of communication passages 28 are provided, the operation can be performed sequentially. This is advantageous, for example, when the capacity of the vacuum source is small.

  In the illustrated embodiment, the elastic packing 15 has a bellows shape. However, the elastic packing 15 is not limited to this, and for example, elastic rubber packing, O-ring, or the like can be used. In any case, it can be moved in conjunction with the movement of the base plate 3.

  The number of leaf springs 9 and the number of recesses 7 on which the leaf springs 9 are placed are also arbitrary, and can be appropriately increased or decreased depending on the set pitch dimension.

  The pitch portions formed on the circumferential surface of the variable spacer 17 can also be, for example, three large, medium, and small. For example, when the number of pitch portions is three, each pitch portion is provided every 120 °, and in the case where a plurality of pitch portions are installed, the installation site of the pitch portions is appropriately changed.

Moreover, the installation ratio of the pitch portion is not necessarily divided equally. For example, if the pitch of the large and small, 60% installation rate of large-pitch portion, the installation rate of the small pitch portion can be 40% of the as. In the case where the pitch of the large, medium and small, 40% installation rate of large-pitch portion, 35 percent installation rate of the medium pitch portion, the installation rate of the small pitch portion can be 25% of the as.

  The timing for changing the pitch between the base plates 3 is arbitrary. Although the workpiece 51 may be being transferred as in the illustrated embodiment, the vertical movement of the movable support portion to the large container 53 after the transfer is performed during the vertical movement of the movable support portion to the small container 52 before the transfer. Sometimes, the pitch between the base plates 3 may be changed.

  The moving direction of the movable support portion is arbitrary. Although the case where the movable support portion is moved in the horizontal direction has been described in the above embodiment, the movable support portion may be moved in the vertical direction or may be moved in an oblique direction.

  The stacking direction of the base plate 3 constituting the movable support portion is arbitrary.

  The shape of the base plate 3 is arbitrary.

  The material of each part is arbitrary, but the base plate 3, the variable spacer 17, and the leaf spring 9 are desirably made of highly durable materials such as metal materials. The elastic packing 15 is preferably made of a material having a large elastic force, such as a plastic material or a rubber material. The suction pad 25 is preferably made of a material having a lightness, workability, chemical resistance, and hardness lower than that of the workpiece, for example, an appropriate plastic material. The distribution plate 23 is preferably made of, for example, an appropriate plastic material or light metal material from the viewpoint of lightness and workability.

  Further, the driving power for working on the workpiece 51 may be not only a vacuum source but also a pressure source, for example.

  The laminate pitch changing device according to the present invention is used to change the pitch between workpieces when a plurality of thin workpieces are juxtaposed in a laminated manner at a predetermined pitch, for example, to transfer solar panels. Can do.
