Description

[Technical Field]

[0001] The present disclosure relates to a laminated body holding device used for laminating conveyed sheet members. [Background Art]

[0002] When laminating sheet members such as sheet-shaped electrodes, for example, a laminated body holding device as disclosed in Patent Document 1 is used. In such a laminated body holding device, in order to clamp and hold a sheet member laminated on a lamination table between a clamp mechanism facing each other across the sheet member and the lamination table, the lamination table is pressed from below by a pressing mechanism. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2021-30566 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] The applicant of the present application has found the following problem. In the laminated body holding device of Patent Document 1, when a new sheet member is laminated onto the laminated sheet members, it is necessary to release the holding state of the sheet members by the clamp mechanism, and the lamination table rises in this process.

[0005] For this reason, in the laminated body holding device of Patent Document 1, while maintaining the holding state of the sheet member by one of the opposing clamp mechanisms, the holding state of the sheet member by the other opposing clamp mechanism is released, one end of a new sheet member is placed on the sheet member on the side of the other clamp mechanism, and the new sheet member is held by the other clamp mechanism.

[0006] Then, the clamping mechanism is released from holding the sheet member, and the other end of the new sheet member is placed on top of the sheet member on the side of the clamping mechanism and held in place by the other clamping mechanism. In this way, the new sheet member is stacked on top of the stacked sheet members.

[0007] Thus, in the laminated material holding device of Patent Document 1, when a new sheet member is to be laminated on top of an already laminated sheet member, it is necessary to operate the opposing clamping mechanisms individually or to place the new sheet member on each of the opposing ends, which presents the problem of a complicated laminated sheet member process.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, specific embodiments to which the present disclosure is applied will be described in detail with reference to the drawings. However, the present disclosure is not limited to the following embodiments. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate.

[0017] First, the configuration of the laminated body holding device according to the present embodiment will be described. The laminated body holding device of the present embodiment is suitable, for example, for laminating sheet members such as sheet-shaped electrodes. FIG. 1 is a perspective view showing the laminated body holding device according to the present embodiment.

[0018] Here, in the following description, a three-dimensional (XYZ) coordinate system is used for clarity of explanation. The positive X-axis side is the front side of the laminated body holding device 1, and the negative X-axis side is the rear side of the laminated body holding device 1. The positive Y-axis side is the left side of the laminated body holding device 1, and the negative Y-axis side is the right side of the laminated body holding device 1. The positive Z-axis side is the upper side of the laminated body holding device 1, and the negative Z-axis side is the lower side of the laminated body holding device 1.

[0019] As shown in FIG. 1, for example, the laminated body holding device 1 includes a base 2, a lamination table 3, leg portions 4, a pressing mechanism 5, a clamp mechanism 6, and a regulation mechanism 7. The base 2 is, for example, a substantially rectangular magnetically levitated linear member when viewed in the Z-axis direction, and is configured to be movable while levitating on a floor surface F (see FIG. 2).

[0020] As shown in Figure 1, the stacking base 3 is positioned on the Z-axis+ side relative to the base 2. The stacking base 3 is, for example, a roughly rectangular plate when viewed from the Z-axis direction. The legs 4 support the stacking base 3 so that it can move in the Z-axis direction. The legs 4 are, for example, positioned near the four corners of the stacking base 3 when viewed from the Z-axis direction.

[0021] The leg portion 4 includes, for example, a support column 4a and a guide mechanism 4b, as shown in Figure 1. The support column 4a extends from the base 2 towards the Z-axis+ side. The guide mechanism 4b includes, for example, a linear guide. That is, the guide mechanism 4b includes a rail 4c and a slider 4d.

[0022] As shown in Figure 1, the rail 4c extends in the Z-axis direction and is fixed to the support column 4a. The slider 4d is movable along the rail 4c in the Z-axis direction and is fixed to the Z-axis side end of the stacking platform 3. This makes the stacking platform 3 movable in the Z-axis direction.

[0023] The pressing mechanism 5 presses the stacking table 3 towards the Z-axis + side. The pressing mechanism 5 is equipped with an elastic body such as a spring, and as shown in Figure 1, the Z-axis - end of the pressing mechanism 5 is fixed to the base 2 so as to be rotatable around a rotation axis extending in the X-axis direction, and the Z-axis + end of the pressing mechanism 5 is fixed to the stacking table 3 so as to be rotatable around a rotation axis extending in the X-axis direction.

[0024] The clamping mechanism 6 holds the sheet member S (see Figure 2) by clamping it with the stacking base 3. As shown in Figure 1, the clamping mechanism 6 comprises a clamping arm 6a, a clamping rod 6b, a sliding mechanism 6c, and a tilting mechanism 6d.

[0025] The clamp arm 6a contacts the sheet member S stacked closest to the Z-axis+ side from the Z-axis+ side in order to hold the sheet member S between the stacking base 3 and the sheet member S. When the sheet member S is held between the stacking base 3 and the clamp mechanism 6, the clamp arm 6a is, for example, a roughly rectangular plate when viewed from the Z-axis direction. Multiple clamp arms 6a are arranged at intervals in the Y-axis direction, as shown in Figure 1, for example.

[0026] The clamp rod 6b extends in the Y-axis direction, as shown in Figure 1, for example, and is positioned on the X-axis side relative to the stacking base 3 when viewed from the Z-axis direction. The X-axis side end of the clamp arm 6a is fixed to the clamp rod 6b.

[0027] The clamp rod 6b is fixed to a slider 6f that is movable in the Z-axis direction along a guide 6e fixed to the base 2, so as shown in Figure 1, for example, that it can pivot about a pivot axis 6j that extends in the Y-axis direction in the tilt mechanism 6d.

[0028] The sliding mechanism 6c moves the clamp arm 6a and clamp rod 6b in the Z-axis direction via the slider 6f. In the sliding mechanism 6c, for example, the slider 6f is pushed down as far as possible towards the Z-axis when the long diameter portion of a cam provided on a rotating shaft 6g that is rotatably supported by the guide 6e and extends in the Y-axis direction is in contact with an arm that extends from the slider 6f toward the Z-axis. As a result, the clamp arm 6a and clamp rod 6b are positioned as far as possible toward the Z-axis.

[0029] At this time, the arm of the slide mechanism 6c is biased toward the Z-axis+ side by an elastic body. In the slide mechanism 6c, for example, the roller follower 6i of the lever 6h fixed to the end of the rotating shaft 6g contacts a sliding fixing cam provided at a first position on the floor surface F where new sheet members are stacked, and the cam rotates clockwise via the lever 6h when viewed from the Y-axis+ side.

[0030] As a result, the downward pressure on the Z-axis side of the slider 6f by the cam is released, and the biasing force of the elastic body pushes the slider 6f upward on the Z-axis side via the arm of the slide mechanism 6c, causing the clamp arm 6a and clamp rod 6b to move on the Z-axis side.

[0031] In the slide mechanism 6c, the rotation axis 6g of the slide mechanism 6c is biased by another elastic body so that the long diameter portion of the cam returns to a state in contact with the arm. When the laminate holding device 1 passes the first position on the floor surface F, the long diameter portion of the cam returns to a state in contact with the arm, and the clamp arm 6a and clamp rod 6b return to the state where they are positioned closest to the Z-axis.

[0032] The tilt mechanism 6d causes the clamp arm 6a and clamp rod 6b to swing around the Y axis. In the tilt mechanism 6d, for example, the clamp rod 6b is fixed via an arm 6k to a swing axis 6j that is rotatably supported by a slider 6f and extends in the Y-axis direction.

[0033] In the tilt mechanism 6d, the major diameter portion of a cam provided on a rotating shaft 6l that is rotatably supported by a slider 6f on the X-axis- side and Z-axis- side with respect to the pivot axis 6j and extends in the Y-axis direction is in contact with the arm 6k. When viewed from the Y-axis+ side, the clamp arm 6a and clamp rod 6b rotate most counterclockwise via the arm 6k. As a result, when viewed from the Z-axis direction, the clamp arm 6a is positioned approximately parallel to the XY plane within the arrangement area of ​​the stacking base 3.

[0034] At this time, the arm 6k of the tilt mechanism 6d is biased clockwise by an elastic body when viewed from the Y-axis+ side. In the tilt mechanism 6d, for example, the roller follower 6n of the lever 6m fixed to the end of the rotation axis 6l contacts the tilt fixing cam provided at a first position on the floor surface F, causing the cam to rotate clockwise via the lever 6m when viewed from the Y-axis+ side.

[0035] As a result, when viewed from the Y-axis + side, the counterclockwise pushing of arm 6k by the cam loosens, and the clamp arm 6a and clamp rod 6b swing clockwise via arm 6k due to the biasing force of the elastic body, and when viewed from the Z-axis direction, clamp arm 6a retracts from within the placement area of ​​the stacking base 3.

[0036] In the tilt mechanism 6d, the rotation axis 6l of the tilt mechanism 6d is biased by another elastic body so that the long diameter portion of the cam returns to a state in contact with the arm 6k. When the stacking device 1 passes the first position on the floor surface F, the long diameter portion of the cam returns to a state in contact with the arm 6k, and the clamp arm 6a returns to a state where it is positioned approximately parallel to the XY plane in the arrangement area of ​​the stacking platform 3 when viewed from the Z-axis+ side.

[0037] Thus, the slide mechanism 6c and the tilt mechanism 6d enable movement of the clamp arm 6a and the clamp rod 6b in the Z-axis direction and oscillation around the Y-axis. However, the configuration of the slide mechanism 6c and the tilt mechanism 6d is illustrative, and any configuration that enables movement of the clamp arm 6a and the clamp rod 6b in the Z-axis direction and oscillation around the Y-axis is acceptable.

[0038] Furthermore, in this embodiment, the clamping mechanism 6 is positioned on the X-axis side relative to the stacking base 3, but the arrangement and number of clamping mechanisms 6 are not limited. Therefore, the clamping mechanisms 6 may be arranged so that they face each other, sandwiching the stacking base 3 between them.

[0039] The restricting mechanism 7 restricts the movement of the stacking platform 3 toward the Z-axis + side. Figure 2 is a diagram illustrating the configuration of the restricting mechanism of the stacking device in this embodiment. Note that Figure 2 shows the clamping mechanism 6 and other components in a simplified manner.

[0040] As shown in Figures 1 and 2, the regulating mechanism 7 comprises a wedge 7a, a stopper 7b, a guide mechanism 7c, a biasing mechanism 7d, and a return mechanism 7e. The wedge 7a is, for example, a roughly right-angled triangular prism when viewed from the X-axis direction and extends in the Y-axis direction. On the Z-axis side face of the wedge 7a, for example, an inclined surface 7f is formed that slopes toward the Z-axis as it moves toward the Y-axis+ side.

[0041] The stopper 7b protrudes from the stacking base 3 toward the Z-axis, as shown in Figure 2, for example, and has an insertion portion 7g into which the wedge 7a is inserted. The Z-axis side surface of the insertion portion 7g has an inclined surface 7h formed thereon, which, for example, slopes toward the Z-axis as it moves toward the Y-axis+ side, corresponding to the inclined surface 7f of the wedge 7a. In this case, the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b should be in approximate surface contact at a self-locking angle so as to restrict the relative movement of the wedge 7a and the stopper 7b.

[0042] The guide mechanism 7c guides the wedge 7a in the Y-axis direction. As shown in Figure 2, the guide mechanism 7c comprises a rail 7i and a slider 7j. The rail 7i extends, for example, in the Y-axis direction and is fixed to the base 2. The slider 7j moves along the rail 7i in the Y-axis direction. The wedge 7a is fixed to the slider 7j via a fixing member 7k.

[0043] The biasing mechanism 7d biases the wedge 7a to the Y-axis + side, for example. The biasing mechanism 7d includes, for example, a tension spring, and as shown in Figure 2, for example, the Y-axis + end of the biasing mechanism 7d is fixed to the base 2 via a fixing member 7l, and the Y-axis - end of the biasing mechanism 7d is fixed to the slider 7j of the guide mechanism 7c.

[0044] The return mechanism 7e moves the wedge 7a to the Y-axis- side, for example, to return it to a preset initial position. Here, the initial position of the wedge 7a is, for example, the position where the wedge 7a is positioned such that the Z-axis-side surface of the stacking table 3 and the Z-axis-side surface of the clamp arm 6a of the clamping mechanism 6 are in approximate contact, when the sheet member S has not yet been transported to the stacking table 3.

[0045] The return mechanism 7e comprises a rod 7m and a bracket 7n (see Figure 4), as shown in Figure 2. The rod 7m extends, for example, in the Y-axis direction, and the Y-axis+ side portion of the rod 7m is supported on the base 2 via a support member 7o to guide the movement of the rod 7m in the Y-axis direction, while the Y-axis- side end of the rod 7m is fixed to the slider 7j of the guide mechanism 7c.

[0046] The bracket 7n is fixed, for example, to a second position where the laminated body holding device 1 stops to return the wedge 7a to its initial position after the lamination of the sheet members S on the floor surface F is completed. When the laminated body holding device 1 reaches the second position, it contacts the Y-axis+ end of the rod 7m, pushing the slider 7j of the guide mechanism 7c toward the Y-axis-, and positioning the wedge 7a in its initial position.

[0047] Furthermore, depending on the amount of movement of the stacking platform 3 in the Z-axis direction, it is preferable that multiple regulating mechanisms 7 be arranged in the X-axis direction, as shown in Figure 1, so that the contact state between the wedge 7a and the stopper 7b is maintained in accordance with the movement of the stacking platform 3 in the Z-axis direction.

[0048] In this case, in order for the Y-axis positive end of the wedge 7a to be smoothly inserted into the insertion portion 7g of the stopper 7b, it is preferable that a roller 7p that can rotate around a rotation axis extending in the X-axis direction is provided on the Y-axis positive end of the wedge 7a, as shown in Figure 1.

[0049] Next, the operation of the laminated material holding device 1 of this embodiment will be described. Figure 3 shows the state in which multiple sheet members are stacked in the laminated material holding device of this embodiment. Figure 4 shows the state in which the wedge returns to its initial position in the laminated material holding device of this embodiment. Figure 5 shows the state in which the stacking table is pushed up to the Z-axis + side in the laminated material holding device of this embodiment. Note that Figures 3 to 5 show the clamp mechanism 6 and the like in a simplified manner.

[0050] Here, the stacking device 1 moves through a stacking region on the floor surface F where multiple first positions are arranged. The wedge 7a is initially positioned, and the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b are in approximate surface contact, restricting the movement of the stacking platform 3 toward the Z-axis + side.

[0051] In this state, first, the clamp arm 6a and clamp rod 6b are moved to the Z-axis+ side by the slide mechanism 6c of the clamp mechanism 6. Then, the clamp arm 6a and clamp rod 6b are swung by the tilt mechanism 6d of the clamp mechanism 6, so that the clamp arm 6a is moved out of the placement area of ​​the stacking base 3 when viewed from the Z-axis direction.

[0052] Next, the sheet member S is placed on the Z-axis + side surface of the stacking base 3, and then the clamp arm 6a and clamp rod 6b are swung by the tilt mechanism 6d of the clamping mechanism 6 to position the clamp arm 6a within the placement area of ​​the stacking base 3 when viewed from the Z-axis direction.

[0053] Then, the sliding mechanism 6c of the clamping mechanism 6 moves the clamp arm 6a and clamp rod 6b toward the Z-axis, and the sheet member S is held in place by being sandwiched between the stacking base 3 and the clamp arm 6a of the clamping mechanism 6.

[0054] At this time, the stacking base 3 is pushed in by the clamp arm 6a of the clamping mechanism 6 by the thickness of the sheet member S and moves toward the Z-axis, releasing the surface contact between the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b.

[0055] Then, due to the biasing force of the biasing mechanism 7d of the regulating mechanism 7, the wedge 7a moves to the Y-axis+ side via the slider 7j of the guide mechanism 7c, and again, as shown in Figure 2, the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b come into near-surface contact, restricting the movement of the stacking table 3 to the Z-axis+ side. In other words, the stacking table 3 is maintained in a state moved to the Z-axis- side by the thickness of the sheet member S.

[0056] By repeating this process, a predetermined number of sheet members S are stacked on the stacking table 3, as shown in Figure 3. At this time, the stacking table 3 is maintained by the regulating mechanism 7 in a state where it is moved toward the Z-axis by the thickness of the stacked sheet members S.

[0057] Therefore, by releasing the clamp mechanism 6 from holding the stacked sheet members S and retracting the clamp arm 6a from the placement area of ​​the stacking base 3, a new sheet member S can be easily stacked on top of the stacked sheet members S.

[0058] In other words, when using the laminated body holding device 1 of this embodiment, when stacking a new sheet member S on top of the stacked sheet member S, it is not necessary to individually operate the clamping mechanisms that face each other on the sheet member, or to place the new sheet member on each of the facing ends, as is the case when using the laminated body holding device of Patent Document 1, thereby simplifying the stacking work of the sheet members S.

[0059] Next, once the stacking of the sheet members S is complete, the slide mechanism 6c of the clamping mechanism 6 moves the clamp arm 6a and clamp rod 6b towards the Z-axis+ side. Then, the tilt mechanism 6d of the clamping mechanism 6 swings the clamp arm 6a and clamp rod 6b, retracting the clamp arm 6a from the placement area of ​​the stacking table 3 when viewed from the Z-axis+ side. This makes the stacked sheet members S ready to be unloaded from the stacking body holding device 1.

[0060] Subsequently, with the stacked sheet members S removed from the stacked body holding device 1, when the stacked body holding device 1 reaches the second position on the floor surface F, the bracket 7n of the return mechanism 7e contacts the rod 7m, and as shown in Figure 4, the slider 7j of the guide mechanism 7c is moved toward the Y-axis side, pushing the wedge 7a into its initial position.

[0061] With the bracket 7n of the return mechanism 7e in contact with the rod 7m in this manner, the surface contact between the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b is released, and the restriction on the movement of the stacking table 3 toward the Z-axis + side is released.

[0062] As a result, the biasing force of the pressing mechanism 5 moves the stacking platform 3 towards the Z-axis + side, and as shown in Figure 5, the inclined surface 7f of the wedge 7a and the inclined surface 7h of the stopper 7b come into near-surface contact again, restricting the movement of the stacking platform 3 towards the Z-axis + side. This makes the stacking device 1 ready to perform the stacking work of new sheet members S, and it returns to the stacking area on the floor surface F.

[0063] As described above, the laminate holding device 1 of this embodiment can restrict the movement of the stacking table 3 toward the Z-axis + side by the restricting mechanism 7. Therefore, by releasing the holding state of the stacked sheet members S by the clamping mechanism 6 and retracting the clamp arm 6a from the placement area of ​​the stacking table 3, a new sheet member S can be easily stacked on top of the stacked sheet members S.

[0064] In other words, when using the laminated body holding device 1 of this embodiment, when stacking a new sheet member S on top of the stacked sheet member S, it is not necessary to individually operate the clamping mechanisms that face each other on the sheet member, or to place the new sheet member on each of the facing ends, as is the case when using the laminated body holding device of Patent Document 1, thereby simplifying the stacking work of the sheet members S.

[0065] Moreover, since the regulating mechanism 7 has a simple configuration using a wedge 7a as described above, the stacking device 1 can be constructed at a lower cost compared to the case where the movement of the stacking platform 3 toward the Z-axis + side is restricted using an actuator or the like.

[0066] Here, for example, when stacking sheet members S using the laminate holding device of Patent Document 1, when stacking a new sheet member S, it is always necessary to restrict the movement of one of the clamping mechanisms toward the Z-axis+ side of the stacking table, and from the perspective of the Z-axis+ side, it is not possible to move one of the clamping mechanisms out of the placement area of ​​the stacking table.

[0067] On the other hand, when stacking sheet members S using the stacking device 1 of this embodiment, the clamping mechanism 6 can be retracted from the placement area of ​​the stacking table 3 when viewed from the Z-axis + side, so that large sheet members S can be stacked using multiple stacking devices 1.

[0068] Note that the configuration of the restricting mechanism 7 in this embodiment is illustrative, and any configuration that can restrict the movement of the stacking table 3 toward the Z-axis+ side, separate from the clamping mechanism 6, is acceptable.

[0069] This disclosure is not limited to the embodiments described above, and may be modified as appropriate without departing from the spirit of the invention. [Explanation of Symbols]
