In FIG. 3, the front side of the page is the front side and the back side is the back side. 7A and 7B, the lower side is the front surface and the upper side is the back surface, respectively.

  The two types of components are, for example, the separator 30 in the fuel cell stack 1 and the membrane electrode assembly 20 in the fuel cell stack 1. In the present embodiment, the order in which the separators 30 and the membrane electrode assemblies 20 that are two types of component parts are alternately stacked is referred to as a “determined stacking order”. As shown in FIGS. 9A and 9B, the separator 30 and the membrane electrode assembly 20 are each manufactured in advance in the previous step.

  The metal separator 30 is manufactured by subjecting a base material to press molding for forming a flow path or heat treatment for improving conductivity.

  As shown in FIG. 8A, the first storage unit 50 is used to store one type of component, for example, the separator 30, in a multi-stage shelf shape. . The first storage unit 50 includes a pair of left and right support columns 51, a lower bar 52 for standing the support columns 51, and a caster 53 attached to the lower surface of the lower bar 52 for easy movement. A pair of support | pillar 51 is connected through the connection bar which is not shown in figure. The first storage unit 50 further includes a plurality of first holding members 54 (corresponding to holding members) that can freely hold and release the respective separators 30 stored in the first storage unit 50. is doing.

  As shown in FIG. 8 (B), the second storage unit 60 stores the other type of components, for example, the membrane electrode assembly 20 in a multi-stage shelf shape. Used for. Similar to the first storage unit 50, the second storage unit 60 includes a pair of left and right support columns 61, a lower bar 62, and a caster 63, and the pair of support columns 61 are connected via a connecting bar (not shown). Has been. The interval between the columns 61 in the second storage unit 60 is set wider than the interval between the columns 51 in the first storage unit 50. The second storage unit 60 further includes a plurality of second holding members 64 (corresponding to holding members) that can freely hold and release the respective membrane electrode assemblies 20 stored in the second storage unit 60. Have).

  Each of the first and second holding members 54 and 64 is between a holding position for holding the membrane electrode assembly 20 and the separator 30 and a holding release position for releasing the held membrane electrode assembly 20 and the separator 30. It is configured to be freely movable. The first and second holding members 54 and 64 are guide portions 55 and 65 for restricting the position where the membrane electrode assembly 20 and the separator 30 are stacked when moving from the holding position to the holding release position (see FIG. 12). ) Is provided. Each of the illustrated first and second holding members 54 and 64 holds the membrane electrode assembly 20 and the separator 30 along the horizontal direction, and each of the first and second holding members 54 and 64 is lowered. The membrane electrode assembly 20 and the separator 30 are moved down from the holding position to the holding release position in order from the side, and are dropped onto the stage 70 vertically and stacked on the stage 70.

  More specifically, the first holding member 54 includes a base portion 56 that is rotatably connected to the support column 51, a plate portion 57 on which the separator 30 is placed, and a non-rotating guide portion 55. The plate portion 57 extends from the base portion 56 to the front side (see FIG. 7A). The pair of left and right first holding members 54 are arranged at the same height position and hold the separator 30 along the horizontal direction. The pair of left and right first holding members 54 are rotated in synchronization by an actuator (not shown).

  Similarly, the second holding member 64 includes a base portion 66 that is rotatably connected to the support column 61, a plate portion 67 on which the membrane electrode assembly 20 is placed, and a non-rotating guide portion 65. Yes. The plate portion 67 extends from the base portion 66 to the back side (see FIG. 7B). The pair of left and right second holding members 64 are arranged at the same height position and hold the membrane electrode assembly 20 along the horizontal direction. The pair of left and right second holding members 64 are rotated in synchronization by an actuator (not shown).

  Both the first and second holding members 54 and 64 are arranged in the height direction at a predetermined pitch, but the height position of the first holding member 54 and the height position of the second holding member 64 are Is different. Thereby, each of the separator 30 and the membrane electrode assembly 20 housed in the first and second housing portions 50 and 60 is held at different height positions. Further, as described above, the interval between the columns 61 in the second storage unit 60 is wider than the interval between the columns 51 in the first storage unit 50. As a result, the second storage unit 60 can be freely combined and released with respect to the first storage unit 50 (see FIGS. 7 and 11). When the first storage unit 50 and the second storage unit 60 are relatively combined, the separator 30 held by the first holding member 54 of the membrane electrode assembly 20 held by the second holding member 64 is obtained. The separators 30 and the membrane electrode assemblies 20 are relatively arranged between each other, and are arranged in a predetermined stacking order, that is, alternately (see FIG. 3). When the arrayed membrane electrode assembly 20 and separator 30 are dropped vertically and stacked on the stage 70, the first and second holding members 54 and 64 are held in order from the lower side. It is moved from the position to the holding release position (see FIG. 4).

  Referring to FIG. 12, guide portion 55 in first holding member 54 has a guide surface 55a extending downward so as to form a path in which separator 30 falls. The left guide surface 55 a abuts on a part of the left end of the separator 30, and the right guide surface 55 a abuts on a part of the right end of the separator 30, thereby regulating the position of the separator 30. The guide portion 55 is provided close to the support column 51 so as not to hinder the combination of the first and second storage portions 50 and 60 and the rotation of the base portion 56 and the plate portion 57.

  In the holding position shown in FIG. 12A, the pair of left and right first holding members 54 hold the separator 30 along the horizontal direction. The end portion of the separator 30 is placed on the plate portion 57. When releasing the holding of the separator 30, the right first holding member 54 is rotated in a counterclockwise direction from the holding position and the left first holding member 54 is rotated in a clockwise direction from the holding position in synchronization. (FIG. 12B). Along with this rotation, the separator 30 falls while moving so that its end slides on the plate portion 57 (FIGS. 12B and 12C). The position of the separator 30 in the middle of dropping is regulated by the left guide surface 55a contacting a part of the left end and the right guide surface 55a contacting a part of the right end. When the pair of left and right first holding members 54 move to the holding release position, the end of the separator 30 moves away from the plate portion 57 and falls vertically downward to be stacked on the stage 70 (FIG. 12 ( D)). Thus, the guide part 55 regulates the position in the left-right direction of the separator 30 in the middle of dropping, thereby regulating the position in the left-right direction when the separators 30 are stacked.

  The guide portion 65 in the second holding member 64 is similarly configured, and the guide surface 65a regulates the position in the left-right direction of the membrane electrode assembly 20 in the middle of dropping, whereby the left and right when the membrane electrode assembly 20 is stacked. The position of the direction is regulated.

  The stage 70 is configured to be movable up and down along the vertical direction, and is preferably raised by a predetermined distance each time it receives the falling membrane electrode assembly 20 and the separator 30. This is because the drop distance between the membrane electrode assembly 20 and the separator 30 can be made uniform, and the occurrence of misalignment during lamination can be reduced.

  The stage 70 has a table 71 for laminating the membrane electrode assembly 20 and the separator 30 and an elevating mechanism 72 for elevating and lowering the table 71. The width of the table 71 is narrower than the interval between the columns 51 in the first storage unit 50. The first and second storage units 50 and 60 are relatively combined so as to straddle the table 71 (see FIG. 7). On the table 71, the membrane electrode assembly 20 and the separator 30 that are released from the lower side are sequentially stacked in order. Positioning pins 73 are erected on the back of the table 71. The positioning pin 73 has a length longer than the height dimension of the stacked body 3. By bringing the back surface of the separator 30 stored in the first storage unit 50 into contact with the positioning pin 73, the position in the front-rear direction when the separators 30 are stacked is regulated. Similarly, by bringing the back surface of the membrane electrode assembly 20 stored in the second storage portion 60 into contact with the positioning pin 73, the position in the front-rear direction when the membrane electrode assembly 20 is stacked is regulated. The elevating mechanism 72 elevates and lowers the table 71 by fluid pressure such as hydraulic pressure, for example.

  The press 80 includes a die 81 that can freely come into contact with the upper surface of the stacked body 3 on the table 71 of the stage 70, and a pressing mechanism 82 that moves the die 81 toward and away from the table 71. By moving the mold 81 closer to the table 71 by the pressing mechanism 82, pressure is applied to all the membrane electrode assemblies 20 and the separators 30 stacked on the table 71.

  Next, a procedure for forming the stacked body 3 in the fuel cell stack 1 by the stacking device 40 will be described.

  Both the separator 30 (FIG. 9A) and the membrane electrode assembly 20 (FIG. 9B) are manufactured in advance in the previous step.

  First, as shown in FIGS. 8A and 8B, the membrane electrode assembly 20 and the separator 30 are stored separately for each type in the first and second storage portions 50 and 60 (storage step). The storing step is performed using a robot that handles the manufactured membrane electrode assembly 20 and the separator 30.

  In this storage step, the separator 30 is stored in a multistage shelf in the first storage unit 50, and the membrane electrode assembly 20 is stored in a multistage shelf in the second storage unit 60. In the storing step, the first holding member 54 holds the separator 30 along the horizontal direction at the holding position, and the second holding member 64 also holds the membrane electrode assembly 20 along the horizontal direction at the holding position. Hold.

  Next, as shown in FIG. 3, the first and second storage units 50 and 60 are relatively combined to be stored in the separator 30 stored in the first storage unit 50 and the second storage unit 60. The membrane electrode assemblies 20 are arranged in a predetermined stacking order (arrangement step).

  In this arrangement step, first, the first storage unit 50 is moved from the front side of the table 71 so as to straddle the table 71 (see FIGS. 10A and 10B). Thereafter, the second storage unit 60 is moved from the front side of the table 71 so as to straddle the table 71 (see FIGS. 11A and 11B). When the first storage unit 50 and the second storage unit 60 are relatively combined, the separator 30 held by the first holding member 54 of the membrane electrode assembly 20 held by the second holding member 64 is obtained. The membrane electrode assemblies 20 and the separators 30 are arranged in a relative order, and are arranged in a predetermined stacking order, that is, alternately. Also in the arrangement step, the first holding member 54 holds the separator 30 along the horizontal direction at the holding position, and the second holding member 64 also holds the membrane electrode assembly 20 along the horizontal direction at the holding position. Hold.

  Next, as shown in FIGS. 4 and 5, by releasing the holding of the membrane electrode assemblies 20 and the separators 30 stored in the first and second storage portions 50 and 60, the membrane electrode assemblies 20 and The separators 30 are stacked on the table 71 of the stage 70 according to a predetermined stacking order, that is, alternately (stacking step).

  In this laminating step, each of the first and second holding members 54 and 64 is moved from the holding position to the holding release position, so that the arrayed membrane electrode assembly 20 and the separator 30 are positively dropped vertically downward. And stacked on the table 71 of the stage 70. At this time, each of the first and second holding members 54 and 64 is moved from the holding position to the holding release position in order from the lower side.

  Furthermore, in the stacking step, when the first and second holding members 54 and 64 are moved from the holding position to the holding release position, the guide portions 55 and 65 are placed on the membrane electrode assembly 20 and the separator 30 that are being dropped. The position in the left-right direction is regulated, and the position in the left-right direction when the membrane electrode assembly 20 and the separator 30 are stacked is regulated (see FIG. 12). The positions of the membrane electrode assembly 20 and the separator 30 in the front-rear direction are regulated by bringing their back surfaces into contact with the positioning pins 73 on the table 71.

  In the laminating step, the table 71 is lifted by a predetermined distance by the elevating mechanism 72 every time the falling membrane electrode assembly 20 and the separator 30 are received. Thereby, the fall distance of the membrane electrode assembly 20 and the separator 30 can be made uniform, and generation | occurrence | production of the shift | offset | difference at the time of lamination | stacking can be reduced.

  Next, as shown in FIG. 6, after the lamination process, the die 81 of the press 80 is moved closer to the table 71 by the pressing mechanism 82, and the membrane electrode assembly 20 and the separator 30 that are alternately laminated on the table 71. Pressure is applied (pressing process).

  After the pressing step, the die 81 of the press 80 is moved away from the table 71, the table 71 is lowered to the initial position, and the laminate 3 formed by laminating the membrane electrode assembly 20 and the separator 30 is carried out from the table 71. To do.

  The empty first and second storage portions 50 and 60 are returned to the previous process for manufacturing the membrane electrode assembly 20 and the separator 30. Thereby, formation of the laminated body 3 in the fuel cell stack 1 is completed.

  FIG. 13A is a diagram for explaining a process when the laminate forming apparatus 40 according to the present invention is used, and FIG. 13B is a case where the proportional laminate forming apparatus 100 is used. It is a figure where it uses for description of this process. The case where a laminated body formed by laminating two types of component parts is taken as an example.

  As shown conceptually in FIG. 13B, the laminate forming apparatus 100 according to the comparative example has two storage parts 101 and 102 for storing two types of component parts separately for each type. And a robot 104 for taking out each component from the storage units 101 and 102 and stacking them on the stage 103 in order according to the stacking order. In contrast, the process of taking out the components once stored in the storage units 101 and 102 and the robot 104 for handling and stacking the components are essential.

  On the other hand, the laminate forming apparatus 40 according to the present invention can be obtained by simply combining the first and second storage portions 50 and 60, as conceptually shown in FIG. The component parts stored in one storage unit 50 and the component parts stored in the second storage unit 60 can be arranged in a predetermined stacking order, and the first and second storage units 50, By releasing the holding of each component housed in 60, two kinds of component parts can be stacked on the stage 70 in accordance with a predetermined stacking order. For this reason, the process which takes out the component once accommodated in the 1st and 2nd accommodating parts 50 and 60, and the robot which handles and laminates a component are unnecessary. Therefore, in the present invention, a plurality of types of component parts can be laminated through a simple process and with a simple facility according to a predetermined lamination order. Furthermore, there is no time required to take out the components once stored in the first and second storage units 50 and 60. Therefore, according to the present invention, it is possible to form a laminate quickly and inexpensively.
