Description

  The present invention relates to a transport apparatus and a transport method.

  When manufacturing an assembly composed of a large number of parts such as an automobile, intermediate parts that are included in the finished product and appear during the manufacturing process are transported from one place to another. For example, in the conventional technology related to parts transportation, a locating pin and a supporting plate are provided in a robot hand, and the workpiece is gripped by approaching the supporting plate from the outside of the side of the workpiece while the locating pin is positioned on the workpiece. There is a technology (see Patent Document 1).

JP 2010-201517 A

  However, there are cases in which other parts, facilities, and the like are adjacently arranged around the parts conveyance place. In Patent Document 1, a support plate that grips a component operates to move in the horizontal direction in order to grip the component or release the grip of the component. At this time, the support plate once moves away from the part so as not to contact the part, approaches the part, and grips the part. In the case of the above transport method, the distance between the parts to be transported and the adjacent parts needs to secure a space (distance) for the movement of the support plate that moves between the parts and the adjacent parts. The present inventor considers the matter of arranging the components in consideration of the positional relationship between the adjacent components and the configuration such as the support plate at the component conveyance place.

  In view of the above, an object of the present invention is to provide a transport apparatus and a transport method in which parts to be transported can be arranged closer to adjacent parts or the like at a transport location.

  The present invention that achieves the above object is a transport apparatus that transports a part to a transport place where one or more adjacent parts are arranged adjacent to each other. The conveying device is inserted into a hole provided on the upper surface of the component, and the component is suspended by engaging with an edge forming the hole, and the suspension of the component is released by removing from the hole. It has an insertion part provided with a hollow spiral shape, and a drive part that rotationally drives the insertion part. The insertion part is inserted close to the hole part while rotating in the first rotation direction by the drive part with the direction intersecting the upper surface as the axis, and the hole part rotating in the second rotation direction opposite to the first rotation direction. It is extracted away from.

  The present invention that achieves the above-described determination is a transport method for transporting a part to a transport place where one or more adjacent parts are arranged adjacent to each other. The conveying method is such that a hollow spiral shape is inserted into a hole provided on the upper surface of a component while rotating in a first rotation direction with the direction intersecting the upper surface as an axis, thereby forming a hole. The part is suspended by engaging the spiral shape with the part. Next, the parts are transferred to a transfer place. Then, after the component is conveyed, the spiral shape is separated from the hole of the component while being rotated in the second rotational direction opposite to the first rotational direction.

  According to the transport apparatus and the transport method of the present invention, it is possible to place a component closer to a component or the like adjacent to the conventional one at a transport location.

  The transfer device 200 includes a base 210, a support 220, a joint portion 230, a first arm 240, a second arm 250, and a holding portion 260, as outlined with reference to FIG. Details will be described below.

  The base 210 is a part serving as a base of the transport apparatus 200 and is configured as a fixed part in contact with the placement surface or the ground. The base 210 is configured as a substantially rectangular parallelepiped with a support 220 attached thereto. The support column 220 is attached to the upper surface of the base 210 and itself is configured as a structure that does not translate or rotate.

  The joint part 230 is formed in a substantially rectangular parallelepiped shape, and is provided with a shape that partially stores the first arm 240 on a side surface of the rectangular parallelepiped shape. The joint portion 230 is configured to be rotatable with respect to the support column 220 using the stacking direction Z (vertical direction) as a rotation axis.

  The first arm 240 is formed in a long bar shape, and one end 241 is housed in the cavity of the joint 230 and is held so as to be rotatable. The first arm 240 is configured to be rotatable about a direction intersecting (orthogonal) with the direction in which the first arm 240 extends, that is, one direction arbitrarily selected in the XY plane (short direction Y in FIG. 11). doing.

  The first arm 240 is connected to the second arm 250 at the other end 242 opposite to the one end 241 housed in the joint 230 as shown in FIG. The other end 242 is configured to be rotatable about one direction arbitrarily selected in the XY plane as in the case of the one end 241. The second arm 250 is connected to the first arm 240 at the other end 242 of the first arm 240 and to the holding unit 260 on the opposite side.

  As shown in FIGS. 12 and 13, the holding unit 260 includes a support column 261, a base 262, and insertion units 263 to 266. The support column 261 is connected to the second arm 250 and is connected to the base 262, and is configured to maintain the state in which the workpiece and the insertion portions 263 to 266 are suspended together with the base 262 during conveyance.

  The base 262 incorporates a power source such as a motor (not shown) that rotates the insertion portions 263 to 266 and a gear (not shown) that transmits the rotational force from the motor to each insertion portion 263 to 266. Has been. In the drawings, illustration of wiring necessary for operation is omitted for convenience.

  The insertion portions 263 to 266 are configured to include a hollow spiral shape 267 formed around an axis parallel to the stacking direction Z as shown in FIGS. The stacking direction Z corresponds to the direction intersecting the pressure plate 121. As shown in FIGS. 15 and 16, the spiral shape 267 is configured in a band shape whose cross section is separated from the rotation axis, but the cross sectional shape is not limited to this as long as the component can be held. The spiral shape 267 of the insertion portions 263 to 266 is configured to be positioned on the inner side of the outer shape of the pressure plate 121 as shown in FIG. 12 when viewed in plan from the axial direction of the spiral.

  The rotating portion 271 shown in FIGS. 14 and 15 is configured to be substantially coaxial with the rotating shaft of the spiral shape 267 and connected to a gear at the base 262 so as to be stored. As shown in FIG. 15, the rotating portion 271 has a spiral shape (corresponding to another spiral shape) and forms a screw gear together with a gear housed in the base 262, thereby rotating the spiral shape 267 in the axial direction. It is configured to be movable in the upward direction d2 and the downward direction d1 in FIG. The helical pitch d3 of the rotating portion 271 is configured to be n times (integer multiple) the pitch d4 of the helical shape 267 of the insertion portions 263 to 266. However, the present invention is not limited to this, and may be the same as the pitch d4 or 1 / n times the pitch d4.

  The pitch d4 of the spiral shape 267 is set in consideration of, for example, the shape of the holes 124 to 127, the thickness of the pressure plate 121, the thickness of the spiral shape 267, the outer diameter and the inner diameter of the spiral shape 267, and the like. For example, the width of the spiral shape 267 is obtained by multiplying the weight of the workpiece by the gravitational acceleration and the safety factor, and dividing the result by multiplying the tensile strength by the allowable tensile stress, and further dividing it by the plate thickness. And multiply by the safety factor.

  The rotation axis of the spiral shape 267 of the insertion portions 263 to 266 is configured to be an axis parallel to the stacking direction Z. As shown in FIG. 12, the rotational axis of the spiral shape 267 is configured to be disposed outside the openings of the holes 124 to 127 when viewed in plan from the axial direction. In FIG. 12, about 1/4 that is less than one turn of the spiral shape 267 enters the inside of the assembled battery 100 from the tip of the spiral shape 267 of the insertion portions 263 to 266, and the assembled battery 100 is thereby suspended. .

  Further, the partial shape 269 on the distal end side of the spiral shape 267 enters the assembled battery 100 through the holes 124 to 127 as shown in FIG. 13, and the upper surface (base end side surface) of the partial shape 269 is formed. Line contact or surface contact is made with the inner surface of the pressure plate 121. On the other hand, when viewed planarly from the axial direction, the partial shape 269 of the spiral shape 267 is 180 degrees out of phase with the partial shape 269, and the partial shape 268 on the proximal end side with respect to the partial shape 269 is a In contrast to the part shape 269, the lower surface (surface on the front end side) is positioned close to the outer surface of the pressure plate 121.

  As described above, when the partial shape 269 of the spiral shape 267 contacts the pressure plate 121 in the vicinity of the edge portion 128, the workpiece can be stably suspended. The spiral shape 267 can be made of stainless steel such as SUS.

(Conveying method)
Next, the conveyance method according to the present embodiment will be described. 9 and 10 are a schematic perspective view and a side view showing a state in which the transport device according to the embodiment of the present invention transports components. FIG. 17 is a flowchart showing the transport method according to this embodiment. 18 and 19 are a perspective view and a front view showing a state immediately before the insertion portion of the transport device is inserted into the hole portion of the component. 20 and 21 are a perspective view and a front view showing a state where the insertion portion of the transport device is inserted into the hole of the component.

  The outline of the conveying method according to the present embodiment will be described with reference to FIG. 17. Part holding (ST1), conveying (ST2), arrangement (ST3), and holding release (ST4) are provided. In the following description, a component adjacent to the assembled battery 100 that is a workpiece is described as an assembled battery 100a (see FIGS. 9, 10, and 21).

  First, the transport device 200 includes the joint portion 230, the first arm 240, and the second arm so that the holding portion 260 is positioned substantially above (directly above) the workpiece (the assembled battery in the present embodiment) from a component storage location (not shown). The arm 250 is operated. And the 1st arm 240 is operated and the holding | maintenance part 260 is approached to a workpiece | work.

  When the holding unit 260 is sufficiently close to the workpiece, the motor housed in the base 262 is operated to rotate the rotating unit 271 in the (first) rotating direction. As a result, the spiral shape 267 of the insertion portions 263 to 266 rotates and the partial shape 269 of the spiral shape 267 of the insertion portions 263 to 266 approaches the holes 124 to 127 and is inserted. And as shown in FIG. 13, the assembled battery 100 is hold | maintained and suspended | suspended by making the base end side surface of the partial shape 269 of the spiral shape 267 contact | abut to the inner surface of the edge part 128 of the hole parts 124-127. The transportable state is entered (ST1).

  From this state, the first arm 240 is rotated upward with reference to the one end 241 of the transport device 200, and the assembled battery 100 is suspended from the holding portion 260 as shown in FIG. And the joint part 230 is rotated so that the assembled battery 100 may be located on the overhead of a conveyance place (ST2). When the assembled battery 100 is positioned substantially above the transport destination as shown in FIGS. 9, 10, and 21, the first arm 240 is rotated with reference to the one end 241, and the assembled battery 100 is moved from the upper side to the lower side. The assembled battery 100a to be placed is placed on the transport destination (ST3).

  When the assembled battery 100 is mounted on the mounting surface, the rotating unit 271 is rotated in the opposite (second) rotation direction when the spiral shape 267 of the inserting units 263 to 266 is inserted into the holes 124 to 127. Thereby, the spiral shape 267 is spaced apart from the holes 124 to 127 in the axial direction while rotating. Then, a partial shape 269 of the spiral shape 267 is extracted from the holes 124 to 127, and the holding of the holes 124 to 127 by the insertion parts 263 to 266 is released (or eliminated) (ST4). If there are other parts that need to be transported, the transport device 200 performs the same operation as described above. The battery pack 100 using the spiral shape 267 is held and released as long as the rotation direction at the time of holding and the rotation direction at the time of release of the holding are reversed, and the insertion portions 263 to 266 are rotated. The directions do not have to match.

(Function and effect)
Next, the function and effect according to this embodiment will be described. According to the transport apparatus 200 and the transport method according to the present embodiment, the holding unit 260 is configured to have the insertion portions 263 to 266 configured in a hollow spiral shape 267. The insertion parts 263 to 266 approach the holes 124 to 127 of the pressure plate 121 corresponding to the surface intersecting the assembled battery 100a that is an adjacent part while rotating in one rotation direction. And it penetrates into the inside of the assembled battery 100 from the hole parts 124-127, engages with the edge part 128, suspends the assembled battery 100, and enables conveyance. Further, the spiral shape 267 of the insertion portions 263 to 266 is configured to release the holding of the assembled battery 100 by being separated while rotating in the rotation direction opposite to that when the insertion portions 263 to 266 are inserted. .

  In this way, the holding portion 260 does not move toward or away from the side plate 123 between the side plate 123 facing the adjacent component at the workpiece transfer location, crosses the side plate 123, and is not disposed so that the adjacent component faces each other. Move toward or away from the pressure plate 121. Therefore, even if the holding part 260 approaches and separates from the workpiece, it does not approach the adjacent component, and it is not necessary to secure a moving space for the equipment between the workpiece and the adjacent component. Therefore, compared with the case where the arm etc. which hold | maintains components move between a workpiece | work and an adjacent component, the required space between a workpiece | work and an adjacent component can be reduced, and components can be arrange | positioned closer to an adjacent component. .

  Further, the spiral shape 267 of the insertion portions 263 to 266 moves toward and away from the assembled battery 100 as a work while being rotated about the stacking direction Z as a rotation axis by the rotation portion 271. For this reason, it is not necessary to separately move holding parts such as a support plate included in the transfer device of the prior art separately in the horizontal direction and the vertical direction. Therefore, compared with the said prior art, the number of actuators etc. which are required for the movement of a holding | maintenance part can be reduced, and the structure of an installation can be simplified. Further, the spiral shape 267 is formed hollow when viewed in plan from the axial direction. Therefore, when entering the workpiece such as the assembled battery 100 from the holes 124 to 127, the amount of entry of the spiral shape 267 into the workpiece can be reduced, and contact with the unit cell 110 or the like existing inside can be avoided during transportation. .

  In addition, as shown in FIG. 12 and the like, the spiral shape 267 is located on the inner side of the outer shape of the upper pressure plate 121 included in the assembled battery 100 as the workpiece when the workpiece is viewed in plan from the axial direction of the spiral shape 267. It is arranged. Thereby, even when the height of the adjacent component is higher than the workpiece to be conveyed, the holding portion 260 does not come into contact with the adjacent component due to the approach or separation of the holding portion 260 with respect to the workpiece. Therefore, the assembled battery 100 or the like, which is a workpiece, can be placed closer to the adjacent parts as described above.

  In addition, when the spiral shape 267 is viewed in plan from the axial direction of the spiral shape 267, about 1/4 of less than one turn from the tip of the spiral shape 267 is inserted into the assembled battery 100, and the assembled battery 100. Is configured to suspend. The spiral shape entering the workpiece has a larger amount of penetration in the axial direction according to the circumference of the spiral shape entering the workpiece. In this regard, the amount of entry into the spiral shape 267 can be reduced by inserting the spiral shape 267 into the work in the range of less than one round as described above. Therefore, a work can be conveyed in the state which avoided contact with the cell 110 etc. which were arrange | positioned in the assembled battery 100 inside.

  Further, the insertion portions 263 to 266 are configured such that the pitch d4 of the spiral shape 267 is n times the pitch d3 of the rotating portion 271. Therefore, the spiral shape 267 can be smoothly inserted into the holes 124 to 127, or the spiral shape 267 can be smoothly extracted from the holes 124 to 127. The same effect can be obtained even if the pitch d4 is the same as the pitch d3 or 1 / n times the pitch d3.

  In addition, this invention is not limited only to embodiment mentioned above, A various change is possible in a claim. FIG. 22 is a cross-sectional view showing a modification of FIG. In the above description, the embodiment in which the surface on the base end side of the partial shape 269 of the spiral shape 267 is in contact with the inner surface of the edge portion 128 of the pressure plate 121 inside the assembled battery 100 has been described.

  However, the present invention is not limited to this, and the tip-side surface of the partial shape 268 moved from the partial shape 269 on the distal end side to the proximal side by about 180 degrees is located outside the assembled battery 100 as shown in FIG. A convex portion 272 that contacts the pressure plate 121 may be provided. Due to the convex portion 272, the spiral shape 267 comes into contact with the pressure plate 121 outside the workpiece. On the other hand, in the assembled battery 100, the base end surface of the partial shape 269 is in contact with the pressure plate 121 as described above. The partial shape 269 and the convex portion 272 each function as a stopper that contacts the pressure plate 121 and prevents the spiral shape 267 from moving in the circumferential direction.

  In this way, by causing the partial shape 269 of the insertion portions 263 to 266 and the convex portion 272 to come into contact with each other on the inner side and the outer side of the pressure plate 121 of the battery pack 100, it is possible to prevent the battery pack 100 that is a workpiece from being shaken during conveyance. Can be suppressed. Further, it is possible to prevent the partial shape 269 of the spiral shape 267 from further entering the inside of the workpiece by rotation.
