[0004] Incidentally, in conveying apparatuses, there is a demand for changing the arrangement orientation of a plurality of battery cells. For example, in order to place a plurality of batteries vertically arranged in a storage section onto a conveying conveyor, it is necessary to change the orientation of the batteries to be horizontal. However, in the above-described conventional conveying apparatus, since the battery cells are rotated while being kept in the horizontal orientation, it is difficult to change the arrangement orientation of the battery cells.

[0005] Accordingly, the present invention has been made in view of these points, and an object of the present invention is to enable easy changing of the arrangement orientation of a plurality of battery cells. [Means for Solving the Problem]

[0006] In one embodiment of the present invention, a conveying device is provided, comprising: a rotating body that can be positioned in a first state and a second state rotated by a predetermined angle from the first state; a through hole that penetrates the rotating body so as to be perpendicular to the axial direction of the rotating body; an insertion member that moves a plurality of battery cells arranged in a first position and inserts them into the through hole when the rotating body is in the first state; a restricting unit that is movable between a standby position spaced away from the through hole and a proximity position close to the through hole, and restricts the movement of the plurality of battery cells inserted into the through hole when it is in the proximity position; a rotation control unit that rotates the rotating body from the first state to the second state with the restricting unit in the proximity position, thereby displacing the plurality of battery cells to a second state rotated by a predetermined angle from the first position; and an extrusion member that pushes the plurality of battery cells in the second position out of the through hole when the rotating body is in the second state.

[0007] Furthermore, the rotation control unit may rotate the rotating body, whose movement of the plurality of battery cells is restricted, from the first state to the second state, which is rotated 90 degrees from the first state, thereby displacing the plurality of battery cells from the first position to the second position.

[0008] Furthermore, the system may also include a conveyor belt for transporting the battery cells in the second orientation, and the extrusion member may push the plurality of battery cells in the second orientation onto the conveyor belt.

[0009] Furthermore, the insertion member may have an adsorption portion for adsorbing the battery cell, and the adsorption portion may move the battery cell that has been adsorbed into the through-hole portion.

[0010] Furthermore, the insertion member may also have a movable portion at its tip, which is provided with the suction portion and which can be inserted into the through-hole when the rotating body is in the first state.

[0011] Furthermore, the restricting portion may be formed along the outer circumferential surface of the rotating body, and may restrict the radial movement of the battery cell perpendicular to the axial direction of the rotating body when the rotating body rotates from the first state to the second state.

[0012] Furthermore, the through-hole portion may be a hole formed so as to intersect with a first direction and a second direction perpendicular to the axial direction.

[0013] Furthermore, the first orientation of the plurality of battery cells may be parallel to the vertical direction, and the second orientation of the plurality of battery cells may be parallel to the horizontal direction.

[0014] Furthermore, the system may also include a conveyor belt for transporting the battery cells in the first position, and the insertion member may push the plurality of battery cells on the conveyor belt to insert them into the through-holes. [Effects of the Invention]

[0017] <Overview of Conveying Device> Fig. 1 is a schematic diagram showing the configuration of a conveying device 1 according to one embodiment. Fig. 1 shows the conveying device 1 viewed from above. The conveying device 1 is a device that conveys a plurality of battery cells 90 in a conveying direction. The conveying device 1 is provided, for example, on a production line for assembling a battery pack from a plurality of battery cells 90. The conveying device 1 includes a housing portion 3, a conveyor belt 6, and a posture changing unit 10.

[0018] The housing portion 3 houses a plurality of battery cells 90 (see Fig. 2). The plurality of battery cells 90 in the housing portion 3 are arranged in a first posture. The plurality of battery cells 90 are arranged in a vertical orientation as the first posture (specifically, an orientation parallel to the vertical direction). The plurality of battery cells 90 are arranged at predetermined intervals in an arrangement direction parallel to the conveying direction in the housing portion 3. As an example, ten battery cells 90 are arranged at predetermined intervals in the arrangement direction. Specifically, ten battery cells 90a, 90b, and 90c shown in Fig. 2 are each provided along the arrangement direction.

[0019] The conveyor belt 6 conveys the plurality of battery cells 90 housed in the housing portion 3 in the conveying direction. The conveyor belt 6 conveys the battery cells 90 in a second posture. The second posture of the battery cell 90 is a horizontal orientation (specifically, an orientation parallel to the horizontal direction). The conveyor belt 6 conveys, for example, the plurality of battery cells 90 to an inspection unit provided downstream in the conveying direction. Inspection of the battery cells 90 is performed in the inspection unit.

[0020] The orientation changing unit 10 changes the orientation of the battery cells 90 when moving the multiple battery cells 90 housed in the housing 3 onto the conveyor belt 6. Specifically, the orientation changing unit 10 changes the orientation of the battery cells 90 in the first orientation within the housing 3 to the second orientation and moves them onto the conveyor belt 6. Here, the orientation changing unit 10 changes the orientation of 10 battery cells 90 arranged in the arrangement direction to the second orientation all at once and moves them onto the conveyor belt 6. This allows the orientation of multiple battery cells 90 to be changed all at once, making it easy to move the battery cells 90 onto the conveyor belt 6.

[0021] <Detailed configuration of the posture change unit> Figure 2 is a schematic diagram showing the configuration of the attitude change unit 10. Figure 3 is a schematic diagram showing the state in which the insertion member 30 has attracted the battery cell 90. Figure 4 is a schematic diagram showing the state in which the battery cell 90 has been inserted into the through hole 25. Figure 5 is a schematic diagram showing the state in which the rotating body 20 has rotated to the second state. Figure 6 is a schematic diagram showing the state in which the extrusion member 40 has pushed out the battery cell 90. Note that Figure 2 shows the view from arrow AA in Figure 1.

[0022] As shown in Figure 2, the posture changing unit 10 includes a rotating body 20, a through hole 25, an insertion member 30, a regulating member 35, an extrusion member 40, and a control unit 50. The rotating body 20 is installed alongside the conveyor belt 6. The rotating body 20 is adjacent to the conveyor belt 6 at the same height in the vertical direction. The rotating body 20 has a cylindrical shape. The axial direction of the rotating body 20 is parallel to the conveying direction of the conveyor belt 6. The rotating body 20 is located above the housing section 3 in the vertical direction.

[0023] The rotating body 20 rotates around the rotation axis 21. The rotation axis 21 is parallel to the depth direction of the paper in Figure 2. Here, the rotating body 20 rotates clockwise around the rotation axis 21. One end of the rotating body 20 in the axial direction is connected to a drive source (for example, a motor) that rotates the rotating body 20. The rotating body 20 stops after rotating by a predetermined angle clockwise.

[0024] The rotating body 20 can be positioned in a first state and a second state which is rotated by a predetermined angle from the first state. For example, the rotating body 20 positioned in the first state shown in Figure 2 can be positioned in the second state shown in Figure 5 which is rotated 90 degrees clockwise from the first state. In this embodiment, for a rotating body 20 that rotates in 90-degree increments, the state of the rotating body 20 when it is stopped before rotation corresponds to the first state, and the state of the rotating body 20 when it is stopped after rotation corresponds to the second state.

[0025] The through-hole portion 25 is a hole that penetrates the rotating body 20. The through-hole portion 25 penetrates the rotating body 20 so as to be perpendicular to the axial direction of the rotating body 20. The through-hole portion 25 is a hole formed to intersect a first direction and a second direction perpendicular to the axial direction. As shown in Figure 1, multiple through-hole portions 25 are provided at predetermined intervals in the axial direction of the rotating body 20.

[0026] As shown in Figure 2, the through-hole portion 25 is a cross-shaped through-hole and has a first hole portion 26 and a second hole portion 27. The first hole portion 26 is a through-hole parallel to the first direction (vertical direction in Figure 2), and the second hole portion 27 is a through-hole parallel to the second direction (horizontal direction in Figure 2). The first hole portion 26 and the second hole portion 27 are circular through-holes. The inner diameters of the first hole portion 26 and the second hole portion 27 are slightly larger than the outer diameter of the cylindrical battery cell 90.

[0027] In the above description, the through-hole portion 25 is assumed to have a first hole portion 26 and a second hole portion 27, but it is not limited to this. For example, the through-hole portion 25 may have only the first hole portion 26.

[0028] The insertion member 30 has the function of moving the battery cells 90 housed in the housing 3 upward and inserting them into the through-hole 25. When the rotating body 20 is in the first position, the insertion member 30 moves the multiple battery cells 90 arranged in the first position and inserts them into the through-hole 25.

[0029] The insertion member 30 is positioned directly above the rotating body 20. As shown in Figure 1, there are as many insertion members 30 as there are through-holes 25, and they are positioned at predetermined intervals along the axial direction of the rotating body 20. Each of the multiple insertion members 30 moves one battery cell 90 and inserts it into the through-hole 25. The insertion member 30 has a movable part 31 and a suction part 32.

[0030] The movable part 31 is axially shaped and moves in a direction perpendicular to the axial direction of the rotating body 20 (specifically, vertically). The movable part 31 is connected to a drive mechanism and moves vertically by the drive mechanism. The movable part 31 moves vertically so as to pass through the through hole 25 when the rotating body 20 is in the first state. Specifically, the movable part 31 moves between a spaced position above the rotating body 20 (Figure 2) and a contact position where the suction part 32 contacts the battery cell 90 housed in the housing part 3 (Figure 3). When the movable part 31 is in the contact position, it passes through the through hole 25 as shown in Figure 3.

[0031] The suction part 32 is the part that adsorbs the battery cell 90, and is, for example, a suction pad. The suction part 32 is provided at the tip of the movable part 31 and moves vertically together with the movable part 31. The suction part 32 is connected to a suction mechanism, for example, via a tube through which air flows. When the movable part 31 is in the contact position, the suction mechanism draws in air, causing the suction part 32 to adsorb to the upper surface of the battery cell 90.

[0032] The insertion member 30 moves the battery cell 90, which has been attracted by the suction part 32, to the through hole 25. Specifically, as shown in Figure 4, the insertion member 30 moves to the insertion position where the battery cell 90 is inserted into the through hole 25. The insertion position is between the separated position and the contact position. When the insertion member 30 is in the insertion position, the suction mechanism releases the air suction, and the suction part 32 stops attracting the battery cell 90.

[0033] The restricting portion 35 restricts the movement of the battery cell 90 within the through-hole portion 25. For example, the restricting portion 35 prevents the battery cell 90 from falling vertically downward immediately after being inserted into the through-hole portion 25 by the insertion member 30. Specifically, the restricting portion 35 contacts the lower surface of the battery cell 90 from which the suction portion 32 has lost its grip, thereby supporting the battery cell 90 and preventing it from falling downward.

[0034] The restricting section 35 is movable between a standby position (Figure 2) spaced away from the through-hole 25 and a proximity position (Figure 4) close to the through-hole 25. The standby position and the proximity position are separated horizontally. When the restricting section 35 is in the proximity position, it restricts the movement of the battery cells 90 inserted into the through-hole 25. That is, when the restricting section 35 is in the proximity position, it supports the lower surfaces of multiple battery cells 90.

[0035] The restricting portion 35 is formed along the outer circumferential surface of the rotating body 20. Specifically, the opposing surface 36 of the restricting portion 35 that faces the outer circumferential surface of the rotating body 20 is a curved surface with a predetermined curvature. As a result, the restricting portion 35 restricts the radial movement of the battery cell 90 perpendicular to the axial direction of the rotating body 20 when the rotating body 20 rotates from the first state to the second state. In other words, the restricting portion 35 restricts the movement of the battery cell 90, which moves radially outward due to centrifugal force when the rotating body 20 rotates. As a result, even if the rotating body 20 rotates while the battery cell 90 is not held by the rotating body 20, the battery cell 90 can be positioned within the through-hole portion 25.

[0036] The extrusion member 40 is a member that pushes out the battery cells 90 from the through-hole 25. When the rotating body 20 is in the second state (Figure 5), the extrusion member 40 pushes out multiple battery cells 90 in the second position from the through-hole 25. Specifically, as shown in Figure 6, the extrusion member 40 pushes multiple battery cells 90 in the second position onto the conveyor belt 6.

[0037] The extrusion members 40 are located on the side opposite to the conveyor belt 6 when viewed from the rotating body 20 in the horizontal direction. As shown in Figure 1, there are as many extrusion members 40 as there are through holes 25, and they are located at predetermined intervals along the axial direction of the rotating body 20. Each of the multiple extrusion members 40 is formed in an axial shape, and the tip of the extrusion member 40 pushes out the battery cell 90. The extrusion members 40 move in the horizontal direction between a standby position and an extrusion position. The standby position is a position away from the rotating body 20. When the rotating body 20 rotates, the extrusion members 40 are in the standby position. The extrusion position is a position where the extrusion members 40 are inserted into the through holes 25 and pushed onto the conveyor belt 6.

[0038] By the way, although the above states that multiple through-holes 25 are provided at predetermined intervals in the axial direction of the rotating body 20, the invention is not limited to this. For example, the axial spacing between multiple through-holes 25 may be reduced, and adjacent through-holes 25 (first hole 26 and second hole 27) may be connected to each other. In this case, multiple insertion members 30 and extrusion members 40 may be a single rectangular parallelepiped structure connected to each other, and the connected through-holes 25 may be inserted through them.

[0039] The control unit 50 controls the operation of the attitude change unit 10. The control unit 50 is, for example, a CPU (Central Processing Unit). The control unit 50 functions as a rotation control unit that controls the rotation of the rotating body 20.

[0040] The control unit 50 rotates the rotating body 20 from the first state to the second state while the restricting unit 35 is in close proximity, displacing the multiple battery cells 90 from the first position to a second position rotated by a predetermined angle. Specifically, the control unit 50 rotates the rotating body 20, which restricts the movement of the multiple battery cells 90, from the first state to the second state rotated by 90 degrees, thereby displacing the multiple battery cells 90 from the first position to the second position (Figure 5). This allows the positions of the multiple battery cells 90 to be displaced simultaneously.

[0041] The control unit 50 controls the movement of the insertion member 30, the regulating unit 35, and the extrusion member 40. Specifically, the control unit 50 moves the insertion member 30 between a separated position and a contact position, moves the regulating unit 35 between a standby position and a close position, and moves the extrusion member 40 between a standby position and an extrusion position. The control unit 50 also controls the suction of air by the suction mechanism.

[0042] <Example of operation of the posture change unit> An example of the operation of the attitude change unit 10 will be explained with reference to Figures 2 to 6. The operation of the attitude change unit 10 is performed by instructions from the control unit 50.

[0043] Here, we assume that the posture changing unit 10 is in the state shown in Figure 2. That is, the rotating body 20 is in the first state where it is stopped (here, the first hole 26 of the through hole 25 is oriented vertically), the insertion member 30 is in the spaced-out position, the regulating member 35 is in the standby position, and the extrusion member 40 is in the standby position. The following describes changing the posture of one battery cell 90, but in reality, the postures of multiple battery cells 90 arranged in the depth direction of the paper in Figure 2 are changed simultaneously by the posture changing unit 10.

[0044] First, the control unit 50 moves the insertion member 30 from a separated position to a contact position. That is, the control unit 50 inserts the insertion member 30 into the first hole 26 of the through hole 25, and brings the suction part 32 into contact with the battery cells 90a arranged vertically in the housing part 3, as shown in Figure 3. Next, the control unit 50 operates the suction mechanism to cause the battery cells 90a to be attracted to the suction part 32.

[0045] Next, the control unit 50 moves the insertion member 30, which is holding the vertically oriented battery cell 90a, upward from the contact position to the insertion position as shown in Figure 4. This puts the battery cell 90a into the first hole 26.

[0046] Next, the control unit 50 moves the restricting unit 35 from the standby position to the proximity position. That is, the control unit 50 moves the restricting unit 35 horizontally to the proximity position as shown in Figure 4. Next, the control unit 50 stops the operation of the suction mechanism and releases the state in which the suction unit 32 is adsorbing the battery cell 90a. As a result, the battery cell 90a in the first hole 26 tries to move downward, but is supported by the restricting unit 35 located in the proximity position.

[0047] Next, the control unit 50 moves the insertion member 30 from the insertion position to a position away from it. Then, the control unit 50 rotates the rotating body 20 in the first state clockwise by 90 degrees to the second state (the state in which the first hole 26 is oriented sideways). As a result, the orientation of the battery cell 90a in the first hole 26 becomes sideways, as shown in Figure 5. The control unit 50 also positions the restricting unit 35 in a close position when the rotating body 20 is rotating from the first state to the second state. As a result, even if the battery cell 90a tries to move outward due to centrifugal force as the rotating body 20 rotates, the restricting unit 35 restricts the movement.

[0048] Next, the control unit 50 moves the extrusion member 40 from the standby position to the extrusion position. As the extrusion member 40 moves, the battery cells 90a in the first hole 26 move onto the conveyor belt 6 as shown in Figure 6. That is, the control unit 50 inserts the extrusion member 40 into the first hole 26 and pushes the battery cells 90a in the first hole 26 onto the conveyor belt 6. As a result, the sideways-oriented battery cells 90a are positioned on the conveyor belt 6.

[0049] Next, the control unit 50 moves the extrusion member 40 to the standby position and moves the regulating unit 35 to the standby position. The control unit 50 also moves the housing unit 3 so that the battery cell 90b is positioned directly below the second hole 27 of the rotating body 20. Then, by performing the operations described in Figures 3 to 6, the control unit 50 changes the orientation of the vertically oriented battery cell 90b to a horizontal position and moves it onto the conveyor belt 6. In other words, the control unit 50 rotates the rotating body 20 by 90 degrees with the battery cell 90b inserted into the second hole 27, thereby changing the orientation of the battery cell 90b to a horizontal position.

[0050] <Variation> In the above, the orientation changing unit 10 changes the orientation of the battery cells 90, which are arranged vertically (first orientation) in the housing section 3, to horizontal (second orientation) and places them on the conveyor belt 6. In contrast, in the modified example shown in Figure 7, the orientation changing unit 110 changes the orientation of the battery cells 90, which are conveyed horizontally (first orientation) by the conveyor belt 106, to vertical (second orientation) and houses them in the housing section 103.

[0051] Figure 7 is a schematic diagram showing the operation of a modified posture changing unit 110. As shown in Figure 7(a), the posture changing unit 110 has a rotating body 120, a through hole 125, an insertion member 130, a restricting part 135, and an extrusion member 140. The posture changing unit 110 also has a control unit 50 (Figure 2) that operates the posture changing unit 110. The configuration of the rotating body 120, the through hole 125, and the restricting part 135 is the same as that of the rotating body 20, the through hole 25, and the restricting part 35 described above, so a detailed explanation is omitted.

[0052] The insertion member 130 pushes the horizontally oriented battery cell 90 on the conveyor belt 106, inserting it into the second hole 127 of the through hole 125 of the rotating body 120, as shown in Figure 7(b). Since the insertion member 130 pushes the battery cell 90 in a horizontal direction, there is no suction part at the tip of the insertion member 130. In the modified example, multiple insertion members 130 are provided, and multiple insertion members 130 simultaneously insert multiple battery cells 90 on the conveyor belt 106 into the second hole 127.

[0053] When the battery cell 90 is inserted into the second hole 127, the control unit 50 rotates the rotating body 120 90 degrees counterclockwise. At this time, the control unit positions the regulating unit 135 in a close position close to the rotating body 120. As a result, the orientation of the battery cell 90 inserted into the second hole 127 is changed to a vertical orientation, as shown in Figure 7(c).

[0054] With the battery cells 90 in the second hole 127 in a vertical position, the control unit 50 moves the extrusion member 140 to the extrusion position and moves the regulating unit 135 to the standby position. In the modified example, multiple extrusion members 140 are provided. As a result, the extrusion members 140 simultaneously push out multiple battery cells 90 in the second hole 127 downwards, and as shown in Figure 7(d), the battery cells 90 are housed in the housing unit 103.

[0055] Multiple through-holes 125 are provided, similar to the through-holes 25, but adjacent through-holes 125 may be connected to each other. In this case, multiple insertion members 130 and extrusion members 140 may form a single rectangular parallelepiped structure, and the connected through-holes 125 may be inserted through them.

[0056] The posture changing unit 110, which is modified, then performs the operations described above to change the horizontally oriented battery cell 90 on the conveyor belt 106 to a vertical orientation and house it in the storage unit 103.

[0057] In the modified version, a movement mechanism is provided to move the attitude changing unit 110 in the depth direction of the page shown in Figure 7. The movement mechanism positions the attitude changing unit 110 at a first position in the depth direction and at a second position obtained by moving it a predetermined distance in the depth direction from the first position (for example, half the length of the diameter of the battery cell 90).

[0058] The control unit 50 houses the battery cell 90, which has been inserted into the first hole 126 and is in a vertical position, into the housing section 103 when the attitude change unit 110 is in a first position by the movement mechanism, and houses the battery cell 90, which has been inserted into the first hole 126 and is in a vertical position, into the housing section 103 when the attitude change unit 110 is in a second position. As a result, the battery cells 90 are arranged in a triangular grid pattern within the housing 103, as shown in Figure 8. This allows for a dense arrangement of the battery cells 90 within the housing 103. Figure 8 is a schematic diagram showing the arrangement of the battery cells 90 within the housing 103. Figure 8 shows the battery cells 90 as viewed from above the housing 103.

[0059] <Effects of this embodiment> The conveying device 1 of the above-described embodiment includes the aforementioned rotating body 20, through-hole portion 25, insertion member 30, regulating portion 35, extrusion member 40, and control unit 50, and changes the battery cell 90 from a first position to a second position as the rotating body 20 rotates. This allows multiple battery cells 90 positioned in the first orientation to be easily changed to the second orientation in a short amount of time.
