Description

The present invention relates to an accommodating device for a plate-shaped member for a fuel cell.

As an accommodating device for a plate-shaped member for a fuel cell of this type, a medium such as air or gas is supplied to the gap between adjacent separators to increase the pressure in the gap between the separators, and the adjacent separators are peeled off from each other. Is disclosed (see Patent Document 1). The separators peeled off by the accommodating device for the fuel cell plate-shaped member are adsorbed and transported one by one.

JP-A-2007-115600

When a fuel cell plate-shaped member such as a laminated separator or a fuel cell is housed in this type of fuel cell plate-shaped member accommodating device, the fuel cell plate-shaped members are brought into close contact with each other due to the lamination. As a result, as shown in FIG. 7, when the fuel cell plate-shaped member W laminated and accommodated in the accommodating device 1 is adsorbed by the suction hand 2 and taken out and laminated on the cell laminating pallet 3, for example, two sheets are used. There is a problem that two sheets are taken out at the same time, and it may not be possible to take out one sheet at a time.

The adhesion between the fuel cell plate-shaped members is generated by the action of the adhesive force, that is, the so-called tack force, which is generated between the adjacent fuel cell cells and the separators. In a fuel cell cell equipped with a gasket, an adhesive component comes out from the gasket in a high temperature environment at the time of cell formation. This adhesive component adheres to the surface of the gasket to generate a tacking force, and further, the adhesive component adhering to the cell-forming mold increases the concentration and reattaches to the gasket, so that the tacking force of the gasket becomes larger. May become.

Since the stacked fuel cell plate-shaped members are stored in a flat stacking state, the lower fuel cell plate-shaped member in the direction of gravity is pressed by the weight of the upper fuel cell plate-shaped member. For example, the plate-shaped member for a fuel cell located at the bottom is pressed by its own weight of about 10 kg, so that the tacking force becomes larger, and the larger the number of laminated sheets and the longer the storage period in the laminated state, the better the adhesion. It will increase.

In order to take out such a fuel cell plate-shaped member one by one, in the fuel cell plate-shaped member accommodating device described in Patent Document 1, a medium such as air or gas is supplied to the gap between the separators. The pressure in the gap is increased to separate the separators from each other, but there are the following problems. That is, in the fuel cell plate-shaped member accommodating device described in Patent Document 1, a medium such as air or gas is supplied to the stacked fuel cell plate-shaped members, which leads to an increase in cost. There is a problem that it will end up.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an accommodating device for a plate-shaped member for a fuel cell, which can be reliably taken out one by one without incurring an increase in cost. To do.

The fuel cell plate-shaped member accommodating device according to the present invention is an accommodating device in which a plurality of fuel cell plate-shaped members are stacked one above the other, and is laminated on the first sheet from the top. A pair of first gears arranged at positions facing one end and the other end of the fuel cell plate-shaped member, and one of the fuel cell plate-shaped members laminated on the second sheet from the top. A pair of second gears arranged at positions facing each other at one end and the other end are provided, and the pair of first gears have a distance between the tooth tips of the first gear. The thickness of one end and the other end of the fuel cell plate-shaped member is larger than the thickness of the one end and the other end, and one end and the other end of the fuel cell plate-shaped member laminated on the first sheet are inserted between the tooth tips. In this state, one end and the other end of the fuel cell plate-shaped member are rotated in an upward direction, and the pair of second gears are placed between the tooth tips of the second gear. The interval is larger than the thickness of one end and the other end of the fuel cell plate-shaped member, and one end and the other end of the second laminated fuel cell plate-shaped member are tooth tips. It is characterized in that it is rotated in a direction of pressing one end portion and the other end portion of the fuel cell plate-shaped member downward in a state of being inserted in the space.

The fuel cell plate-shaped member accommodating device according to the present invention is an accommodating device that accommodates a plurality of fuel cell plate-shaped members in a vertically stacked state, and is laminated on the first sheet from the top. A pair of first gears arranged at positions facing one end and the other end of the fuel cell plate-shaped member, and one end of the fuel cell plate-shaped member laminated on the second sheet from the top. A pair of second gears, which are arranged at positions facing each other at the portion and the other end portion, are provided. Then, the pair of first gears were laminated on the first sheet in which the distance between the tooth tips of the first gears was larger than the thickness of one end portion and the other end portion of the fuel cell plate-shaped member. With one end and the other end of the fuel cell plate-shaped member inserted between the tooth tips, the fuel cell plate-shaped member is rotated in the direction of lifting one end and the other end upward. .. Then, the pair of second gears were laminated on the second sheet in which the distance between the tooth tips of the second gears was larger than the thickness of one end portion and the other end portion of the fuel cell plate-shaped member. With one end and the other end of the fuel cell plate-shaped member inserted between the tooth tips, the fuel cell plate-shaped member is rotated in a direction of pressing one end and the other end downward. ..

According to this configuration, due to the rotation of the pair of first gears, one end and the other end of the plate-shaped member for the fuel cell of the first fuel cell have a force to move upward in the stacking direction, that is, in the stacking direction. A force that lifts upward acts.

Then, due to the rotation of the pair of second gears, a force for pressing downward in the stacking direction acts on one end portion and the other end portion of the second fuel cell plate-shaped member. As a result, the fuel cell plate-shaped member laminated on the first sheet from the top is peeled off from the fuel cell plate-shaped member laminated on the second sheet from the top.

According to the present invention, it is possible to provide an accommodating device for a plate-shaped member for a fuel cell, which can be reliably taken out one by one without increasing the cost.

In the pair of second gears 23, the distance between the tooth tips is larger than the thickness of both ends 10t of the cell 10, and both ends of the second laminated cell 10 are between the tooth tips. It has a configuration in which both ends 10t of the cell 10 are rotated in a downward direction while being inserted.

With this configuration, a moment acts on both ends of the first stacked cell 10 from the top in a direction in which the cells 22 are lifted upward in the stacking direction by the pair of first gears 22. Then, a moment acts on both ends of the second stacked cell 10 from the top in a direction of being pressed downward by the pair of second gears 23. As a result, the effect that the cell 10 laminated on the first sheet from the top is peeled off from the cell 10 laminated on the second sheet from the top can be obtained. Therefore, when the cells 10 stacked on the first sheet from the top are conveyed by an operator or a conveying device, the effect that the cells 10 are surely taken out one by one and conveyed can be obtained.

Further, in the accommodating device 20 of the cell 10 according to the present embodiment, feedback control is performed to the lifting mechanism 25 of the control unit by the data signal transmitted from the sensor 24. As a result, the control unit promptly arranges both ends of the first cell 10 from the top at a height position facing the pair of first gears 22, and the second cell from the top. The effect that both ends of the 10 can be arranged at height positions facing the pair of second gears 23 can be obtained.

Further, the accommodating device 20 of the cell 10 according to the present embodiment has an effect that the problem in the conventional accommodating device can be solved. That is, in the conventional accommodating device, when the cells are sucked by the suction hand of the transport device, the second cell is attached to the first stacked cell and transported, and the number of stacked fuel cell stacks is increased. There is also a problem that the number of cells increases, and that the second cell falls while being transported by adhering to the first cell, causing a problem such as deformation of the cell.

In the accommodating device 20 of the cell 10 according to the present embodiment, the accommodating device 20 peels off the first cell from the top, which is stacked, from the second cell from the top. The cells are not conveyed at the same time, the cell 10 is not dropped during the transfer, the deformation defect of the cell 10 is reduced, the stacking count error with respect to the number of stacked sheets in the fuel cell stack is reduced, and the cell 10 is dropped. The effect of reducing equipment downtime can be obtained.

In the conventional accommodating device for the plate-shaped member for a fuel cell, the pressure in the gap is increased by supplying a medium such as air or gas to the gap between the cells, and the cells are peeled off from each other. The conventional accommodating device for the plate-shaped member for a fuel cell supplies a medium such as air or gas to the laminated plate-shaped member for the fuel cell, so that there is a problem that the cost is increased. Since the accommodating device 20 of the cell 10 according to the present embodiment can separate the cells from each other without supplying such a medium such as air or gas, the problem of increasing the conventional cost is solved. The effect of being able to do is obtained.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs are designed without departing from the spirit of the present invention described in the claims. You can make changes.
