Description

Technical Field

[0001] This invention relates to a conveying and holding tool that holds an object to be conveyed or a support that supports the object to be conveyed.

Background Art

[0002] Conventionally, there has been a clamper that clamps and unclamps a fixed object using air (see, for example, Non-Patent Document 1). As shown in FIG. 13, in this clamper 21, the ball 24 is pushed out by the movement of the shaft 23 inside the main body 22, and the fixed object is clamped when the ball 24 hits the tapered surface (not shown) of the fixed object. Here, the movement of the shaft 23, that is, the clamping and unclamping, was controlled by the air supplied into the main body 22. The illustrated clamper 21 is of the spring clamp type. When air is discharged, the shaft 23 moves toward the clamping side by the force of the spring 25, and when air is supplied, the shaft 23 moves toward the unclamping side by the force of the air.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the conventional clamper 21, since it operates with air, it is troublesome because air equipment is required and a supply path for air to the clamper 21 needs to be secured.

[0005] This invention is made to solve the above-mentioned conventional drawbacks, and its object is to provide a conveying and holding tool that can easily perform unlinking (disconnection) and linking to an object to be held without using air.

Means for Solving the Problems

[0006] In order to achieve the above object, the conveying and holding tool according to this invention has the following configuration. That is, The conveying and holding tool according to the invention described in claim 1 is a conveying and holding tool that is attached to a conveying device and holds an object to be conveyed or a support that supports the object to be conveyed as an object to be held. This conveying and holding tool includes a main body that is fixedly attached to the conveying device, an operating body and an actuating body that are movably provided on the main body, a linkage mechanism, a pressing member, and an elastic member. Here, the operating body is movable between a first operating position and a second operating position, and when the main body approaches or contacts a placement surface on which the object to be held is directly or indirectly disposed, the operating body is pushed by the placement surface and is in the first operating position, and when the main body moves away from the placement surface, the operating body is in the second operating position without being pushed by the placement surface. The actuating body is slidable in a direction parallel to the placement surface. The linkage mechanism links the movement of the operating body and the sliding movement of the actuating body, and by this linkage mechanism, when the operating body is in the first operating position, the actuating body is in a first actuating position, and when the operating body is in the second operating position, the actuating body is in a second actuating position. The elastic member is provided to elastically bias the actuating body toward the side from the first actuating position to the second actuating position. The main body includes a holding wall that extends in the sliding movement direction of the actuating body and holds the pressing member, and the holding wall has one wall surface and the other wall surface that form the thickness of the holding wall. And a holding hole through which the pressing member is inserted is provided in the holding wall in the thickness direction. Further, the actuating body includes an opposing surface that opposes the one wall surface, and a holding surface that is relatively located far from and an acting surface that is relatively located close to the one wall surface are provided on the opposing surface. Therefore, when the actuating body is in the first actuating position, the holding surface faces the pressing member, and the pressing member is allowed to move to the side where the amount of protrusion from the other wall surface becomes smaller or no longer protrudes, and the pressing member does not engage with an engaging portion provided on the object to be held, and the connection between the main body and the object to be held is in a released state.When the actuating body is in the second actuating position, the acting surface faces the pressing member, and the pressing member is pushed by the acting surface so that a part of it protrudes from the other wall surface, and the pressing member engages with the engaging portion provided on the object to be held, thereby connecting the main body and the object to be held.

[0007] According to this transfer and holding tool, the transfer and holding tool is attached to the transfer device. This transfer and holding tool includes a main body, an operating body, an actuating body, an interlocking mechanism, a pressing member, and an elastic member. When the operating body is pushed against the placement surface, it is in the first operating position. The actuating body is in the first actuating position by the interlocking mechanism with the operating body, and the holding surface of the actuating body faces the pressing member inserted into the holding hole of the holding wall of the main body. The pressing member is allowed to move toward the side where the protruding amount from the other wall surface of the holding wall of the main body becomes smaller or does not protrude. Therefore, the transfer device moves the transfer and holding tool along the placement surface so that the pressing member faces the engaging portion of the object to be held. At this time, as described above, the pressing member is allowed to move toward the side where the protruding amount from the other wall surface of the holding wall of the main body becomes smaller or does not protrude, and the pressing member does not engage with the engaging portion of the object to be held, and the connection between the main body (transfer and holding tool) and the object to be held is in a released state. After that, when the transfer and holding tool is moved away from the placement surface, the operating body moves away from the placement surface, so that it is no longer pushed by the placement surface. By the interlocking mechanism and the elastic member, the operating body moves to the second operating position, and the actuating body slides to the second actuating position. Then, the pressing member is pushed by the acting surface of the actuating body and engages with the engaging portion provided on the object to be held, and the main body (transfer and holding tool) and the object to be held are connected, and the object to be held is held by this transfer and holding tool.

[0008] Further, the transfer and holding tool according to the invention described in claim 2 is the transfer and holding tool according to claim 1, wherein the holding wall is formed in a cylindrical shape, the inner peripheral surface of the holding wall serves as the one wall surface, and the outer peripheral surface of the holding wall serves as the other wall surface. The actuating body includes a fitting shaft portion fitted inside the holding wall, and the facing surface is provided on the outer periphery of the fitting shaft portion.

[0009] Further, in the conveying and holding tool according to the invention described in claim 3, in the conveying and holding tool according to claim 1, the holding wall is formed in a cylindrical shape, the outer peripheral surface of the holding wall serves as the one wall surface, and the inner peripheral surface of the holding wall serves as the other wall surface. And the operating body includes a fitting cylinder portion fitted outside the holding wall, and the opposing surface is provided on the inner periphery of the fitting cylinder portion.

[0010] Further, in the conveying and holding tool according to the invention described in claim 4, in the conveying and holding tool according to any one of claims 1 to 3, the movement of the operating body is a sliding movement in a direction perpendicular to the placement surface. And the interlocking mechanism includes an inclined surface provided on one of the operating body or the operating body and inclined with respect to the sliding direction of the one member, and a contact portion provided on the other member and contacting the inclined surface.

[0011] Further, in the conveying and holding tool according to the invention described in claim 5, in the conveying and holding tool according to any one of claims 1 to 3, the movement of the operating body is a rotational movement around an axis facing in a direction parallel to the placement surface and perpendicular to the sliding direction of the operating body. And the interlocking mechanism includes a first contact portion provided on the operating body and a second contact portion provided on the operating body and contacting the first contact portion.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[0015] FIGS. 1 to 9 show an embodiment of the present invention. In the figures, reference numeral 1 indicates a transport device. 2 indicates an object to be held. 3 indicates an arrangement surface on which the object to be held 2 is directly or indirectly arranged. 4 indicates a transport holder, and this transport holder 4 is attached to the transport device 1 and holds the object to be transported or a support for supporting the object to be transported as the object to be held 2.

[0016] The transfer and holding device 4 includes a main body 5 fixedly attached to the transfer device 1, an operating body 6 and an actuating body 7 movably provided on the main body 5, a linkage mechanism 8, a pressing member 9, and an elastic member 10. Here, the operating body 6 is movable between a first operating position and a second operating position. When the main body 5 approaches or contacts the placement surface 3, it is pushed by the placement surface 3 and is in the first operating position (see Fig. 3). When the main body 5 moves away from the placement surface 3, it is not pushed by the placement surface 3 and is in the second operating position (see Figs. 2 and 4). The actuating body 7 is slidable in a direction parallel to the placement surface 3. The linkage mechanism 8 interlocks the movement of the operating body 6 and the sliding movement of the actuating body 7. By the linkage mechanism 8, when the operating body 6 is in the first operating position, the actuating body 7 is in the first actuating position (see Fig. 3), and when the operating body 6 is in the second operating position, the actuating body 7 is in the second actuating position (see Figs. 2 and 4). The elastic member 10 is provided to elastically bias the actuating body 7 toward the side from the first actuating position to the second actuating position.

[0017] Further, the main body 5 includes a holding wall 5a that extends in the sliding movement direction 7a of the actuating body 7 and holds the pressing member 9. The holding wall 5a has one wall surface 5b and the other wall surface 5c that form the thickness of the holding wall 5a. A holding hole 5d through which the pressing member 9 is inserted is provided in the holding wall 5a in its thickness direction. On the other hand, the actuating body 7 includes a facing surface 7b facing one wall surface 5b of the holding wall 5a. A restraining surface 7c located relatively far and an acting surface 7d located relatively close are provided on this facing surface 7b with respect to one wall surface 5b.

[0018] Therefore, when the actuator 7 is in the first operating position, the holding surface 7c faces the pressing member 9, and the pressing member 9 is allowed to move toward the side where the protruding amount from the other wall surface 5c of the holding wall 5a becomes smaller or no longer protrudes. The pressing member 9 disengages the main body 5 (carrying and holding tool 4) from the object 2 to be held without engaging with the engaging portion 2a provided on the object 2 to be held (see FIG. 3). When the actuator 7 is in the second operating position, the acting surface 7d faces the pressing member 9, and the pressing member 9 is pushed by the acting surface 7d to partially protrude from the other wall surface 5c of the holding wall 5a. The pressing member 9 engages with the engaging portion 2a provided on the object 2 to be held, thereby connecting the main body 5 (carrying and holding tool 4) and the object 2 to be held (see FIG. 4).

[0019] Specifically, the holding wall 5a of the main body 5 is formed in a cylindrical shape, the inner peripheral surface of the holding wall 5a serves as the one wall surface 5b, and the outer peripheral surface of the holding wall 5a serves as the other wall surface 5c. The actuator 7 includes a fitting shaft portion 7e that is fitted inside the holding wall 5a, and the opposing surface 7b is provided on the outer periphery of the fitting shaft portion 7e.

[0020] Further, the movement of the operating body 6 is a sliding movement in a direction perpendicular to the placement surface 3. Therefore, the interlocking mechanism 8 includes an inclined surface 8a provided on one of the members of the operating body 6 or the actuator 7 and inclined with respect to the sliding direction of the one member, and a contact portion 8b provided on the other member and in contact with the inclined surface 8a. In the illustrated embodiments, they are all inclined surfaces. That is, for example, the operating body 6 is provided with a first inclined surface 801 as the inclined surface 8a, and the actuator 7 is provided with a second inclined surface 802 that is inclined with respect to the sliding direction 7a of the actuator 7 and mates with the first inclined surface 801 as the contact portion 8b.

[0021] Specifically, the transfer device 1 consists of an industrial robot, and a transfer holder 4 is attached to the arm 1a of the robot. More specifically, an attachment 11 (in the illustrated embodiment, an L-shaped attachment) is attached to the arm 1a, and the transfer holder 4 is attached to the attachment 11. That is, the transfer holder 4 is attached to the arm 1a of the robot via the attachment 11. The object to be held 2 is a support (in the illustrated embodiment, a placing support) that supports the object to be transferred (for example, a workpiece to be processed, a fixture to which the workpiece is attached, jigs, etc.). A connecting hole 2b is provided in the object to be held 2, and the above-described engaging portion 2a is formed on the inner peripheral surface thereof. This engaging portion 2a is composed of an inclined surface whose diameter expands from the mouth side to the back side of the connecting hole 2b. In the illustrated embodiment, the connecting hole 2b is a hole inside a cylindrical auxiliary member 2c, and the auxiliary member 2c is embedded in the object to be held 2. Then, the object to be held 2 is directly arranged so as to be placed on the placement surface 3 (in the illustrated embodiment, a horizontal plane). At this time, a placement frame 12 is provided on the placement surface 3, and this placement frame 12 supports the object to be held 2 so that it does not slide on the placement surface 3 (specifically, supports it by surrounding the four corners).

[0022] In the case of the transfer and holding tool 4, the main body 5 includes a rectangular parallelepiped-shaped and horizontally long main body portion 5e, an intermediate protruding portion 5f that protrudes slightly laterally from the main body portion 5e, and the aforementioned holding wall 5a that further protrudes laterally. Therefore, when connecting the main body 5 (transfer and holding tool 4) and the object to be held 2, the holding wall 5a is inserted into a connection hole 2b provided in the object to be held 2. In this main body 5, there are a first hole 5g into which an operating body 6 is inserted and slides, and a second hole 5h into which an actuating body 7 is inserted and slides. Specifically, the first hole 5g is formed in the main body portion 5e so that the side facing the placement surface 3 is open, and is formed in the vertical direction that is perpendicular to the placement surface 3. The second hole 5h is formed so as to communicate orthogonally with the first hole 5g, extends from the main body portion 5e to the intermediate protruding portion 5f, and is further formed in the horizontal direction that is parallel to the placement surface 3 so as to form the inside of the cylindrical holding wall 5a. This second hole 5h is formed with a large diameter in the portion of the main body portion 5e and the intermediate protruding portion 5f, and is formed with a small diameter in the portion of the holding wall 5a, and a stepped portion 5k is formed at the boundary between the large diameter hole portion 5i and the small diameter hole portion 5j. Further, in the illustrated embodiment, three holding holes 5d are provided in the holding wall 5a, and these holding holes 5d, 5d are arranged at equal intervals in the circumferential direction of the holding wall 5a.

[0023] The operating body 6 is formed in a columnar shape with the sliding direction 6a of the operating body 6 as the axis, and the first inclined surface 801 is provided at its tip. Further, in order to prevent the operating body 6 from falling off and restricting rotation, a groove 6b extending in the sliding direction 6a of the operating body 6 is provided on the side surface of the operating body 6, and a convex portion 5m that fits into the groove 6b is provided on the main body 5.

[0024] The actuating body 7 is formed in a columnar shape with the direction 7a of the sliding movement of the actuating body 7 as the axis, and the second inclined surface 802 is provided at the tip facing the operating body 6 side. Further, the actuating body 7 has a large-diameter formation at the tip portion where the second inclined surface 802 is provided, and other portions are formed with a small diameter, and a stepped portion 7h is formed at the boundary between the large-diameter shaft portion 7f and the small-diameter shaft portion 7g. And the tip side of the small-diameter shaft portion 7g becomes the aforementioned fitting shaft portion 7e, and a holding surface 7c and an acting surface 7d are provided on the opposing surface 7b provided on the outer peripheral surface thereof. The holding surface 7c is formed to be recessed from the opposing surface 7b so as to be located far from one wall surface 5b of the holding wall 5a. The acting surface 7d has an inclined acting surface 7i on the side closer to the holding surface 7c and a flat surface 7j on the side farther from the holding surface 7c in the sliding movement direction 7a of the actuating body 7. Specifically, in the sliding movement direction 7a of the actuating body 7, from the side closer to the holding surface 7c to the side farther away, the inclined acting surface 7i is inclined so as to approach one wall surface 5b of the holding wall 5a, and the flat surface 7j is formed to be parallel to the sliding movement direction 7a of the actuating body 7 after crossing the inclined acting surface 7i.

[0025] The pressing member 9 is formed in a spherical shape and is inserted into each of the three holding holes 5d, 5d. Further, the elastic member 10 is composed of a coil spring (specifically, a compression coil spring), is within the large-diameter hole portion 5i of the second hole 5h, is fitted to the small-diameter shaft portion 7g of the actuating body 7, and is arranged to be compressed between the stepped portion 5k of the second hole 5h and the stepped portion 7h of the actuating body 7.

[0026] Figures 5 to 9 show the process of holding the object 2 by the transfer holder 4. In the first stage shown in FIGS. 5 and 6, the object 2 is placed on the placement surface 3, and the transfer holder 4 is attached to the arm 1a of the robot which is the transfer device 1 via the attachment 11, and is located above and in front of the object 2 (in the illustrated embodiment, to the left) and away from the placement surface 3. At this time, the operating body 6 of the transfer holder 4 is in the second operating position without being pressed against the placement surface 3, and the actuating body 7 is in the second actuating position, and the acting surface 7d (specifically, the flat surface 7j) faces the pressing member 9 (see FIG. 2). Further, the attachment 11 is provided with a guide pin 11a protruding therefrom, and the object 2 is provided with a guide hole 2d into which the guide pin 11a is inserted (see FIG. 5).

[0027] In the second stage shown in FIG. 7, the transfer holder 4 is lowered to bring the main body 5 closer to or into contact with the placement surface 3 (in the illustrated embodiment, closer). Then, the operating body 6 is pushed by the placement surface 3 and moves (slides) from the second operating position to the first operating position (see FIG. 3), and the actuating body 7 slides from the second actuating position to the first actuating position (see FIG. 3) by the linkage mechanism 8. When the actuating body 7 slides to the first actuating position, the holding surface 7c of the actuating body 7 faces the pressing member 9, and the pressing member 9 is allowed to move to a side where the protruding amount from the other wall surface 5c (in the illustrated embodiment, the outer peripheral surface) of the holding wall 5a becomes smaller or does not protrude.

[0028] In the third stage shown in FIG. 8, the transfer holder 4 is advanced along the placement surface 3 toward the object 2 side, the holding wall 5a is inserted into the connecting hole 2b of the object 2, and the pressing member 9 is opposed to the engaging portion 2a in the connecting hole 2b (see FIG. 3). At this time, the pressing member 9 is not engaged with the engaging portion 2a, and the connection between the main body 5 (transfer holder 4) and the object 2 is in a released state.

[0029] In the fourth stage shown in FIG. 9, the transfer holder 4 is raised together with the object 2 to be held, and the main body 5 is moved away from the placement surface 3. Then, the operating body 6 moves away from the placement surface 3 and is no longer pushed by the placement surface 3. By the interlocking mechanism 8 and the elastic member 10, the operating body 6 moves (slides) from the first operating position to the second operating position, and the actuator 7 slides from the first operating position to the second operating position (see FIG. 4). When the actuator 7 slides to the second operating position, the working surface 7d (specifically, the inclined working surface 7i) of the actuator 7 faces the pressing member 9, and the pressing member 9 is pushed by the working surface 7d (inclined working surface 7i) so that a part of it protrudes from the other wall surface 5c of the holding wall 5a and engages with the engaging portion 2a of the object 2 to be held. In this way, the main body 5 (transfer holder 4) and the object 2 to be held are connected.

[0030] Next, the operation and effect of the transfer holder 4 having the above configuration will be described. According to this transfer holder 4, the transfer holder 4 is attached to the transfer device 1. This transfer holder 4 includes a main body 5, an operating body 6, an actuating body 7, an interlocking mechanism 8, a pressing member 9, and an elastic member 10. As shown in FIG. 3, when the operating body 6 is pushed against the placement surface 3, it is located at the first operating position. The actuating body 7, by means of the interlocking mechanism 8 with the operating body 6, is located at the first actuating position, and the holding surface 7c of the actuating body 7 faces the pressing member 9 inserted into the holding hole 5d of the holding wall 5a of the main body 5. The pressing member 9 is allowed to move toward the side where the protruding amount from the other wall surface 5c of the holding wall 5a becomes smaller or no longer protrudes. Therefore, by the transfer device 1, the transfer holder 4 is moved along the placement surface 3 so that the pressing member 9 faces the engaging portion 2a of the object to be held 2. At this time, as described above, the pressing member 9 is allowed to move toward the side where the protruding amount from the other wall surface 5c of the holding wall 5a becomes smaller or no longer protrudes, and the pressing member 9 does not engage with the engaging portion 2a of the object to be held 2, and the connection between the main body 5 (transfer holder 4) and the object to be held 2 is in a released state. Thereafter, as shown in FIG. 4, when the transfer holder 4 is moved away from the placement surface 3, the operating body 6 moves away from the placement surface 3, so that it is no longer pushed by the placement surface 3. By the interlocking mechanism 8 and the elastic member 10, the operating body 6 moves to the second operating position (in the illustrated embodiment, it slides), and the actuating body 7 slides to the second actuating position. Then, the pressing member 9 is pushed by the acting surface 7d (specifically, the inclined acting surface 7i) of the actuating body 7 and engages with the engaging portion 2a provided on the object to be held 2, and the main body 5 (transfer holder 4) and the object to be held 2 are connected, and the object to be held 2 is held by this transfer holder 4. That is, by providing the operating body 6 that is pushed and operated against the placement surface 3 in this way, the non-connection (connection release) and connection to the object to be held 2 can be easily performed without using air.

[0031] Note that the present invention is not limited to the above-described embodiments, and various other modifications are possible. For example, the transfer device 1 may be a dedicated device specialized for the object to be held 2 instead of a general-purpose robot.

[0032] Further, the object 2 to be held may not be a support for supporting the object to be conveyed, but may be the object to be conveyed itself.

[0033] Further, the object 2 to be held may not be directly disposed on the placement surface 3, but may be indirectly disposed via a pedestal or the like. Also, the object 2 to be held may be indirectly disposed on the placement surface 3 such that the placement surface 3 is a vertical surface and is placed on a bracket protruding from the vertical surface. In this case, the conveying and holding tool 4 can be advanced from below along the placement surface 3 toward the object 2 to be held, and the object 2 to be held can be supported from below by this conveying and holding tool 4 (specifically, the main body 5).

[0034] Also, as the interlocking mechanism 8, a first inclined surface 801 as an inclined surface 8a is provided on the operating body 6, and a second inclined surface 802 as a contact portion 8b is provided on the operating body 7. In this case, both are inclined surfaces. However, only one of them may be an inclined surface, and the other may be a contact portion such as an arc shape or an angular shape that contacts the inclined surface.

[0035] Also, as shown in FIG. 10, the positional relationship between one wall surface 5b and the other wall surface 5c of the holding wall 5a may be reversed. That is, the holding wall 5a may be formed in a cylindrical shape, the outer peripheral surface of the holding wall 5a may be one wall surface 5b, and the inner peripheral surface of the holding wall 5a may be the other wall surface 5c. At this time, the operating body 7 includes a fitting cylinder portion 7k fitted outside the holding wall 5a, and an opposing surface 7b is provided on the inner periphery of the fitting cylinder portion 7k. In the object 2 to be held, a connecting shaft 2e protruding from the object 2 to be held is provided, and an engaging portion 2a is formed on the outer peripheral surface thereof. The engaging portion 2a is composed of an inclined surface whose diameter decreases from the tip side to the base side of the connecting shaft 2e. In the illustrated embodiment, the connecting shaft 2e is provided on an axial auxiliary member 2f, and the auxiliary member 2f is attached to the object 2 to be held. When connecting the main body 5 (conveying and holding tool 4) and the object 2 to be held, the holding wall 5a is fitted onto the connecting shaft 2e.

[0036] Also, as shown in FIG. 11, the movement of the operating body 6 may be a rotational movement. Specifically, the movement of the operating body 6 may be a rotational movement about an axis 6c that is perpendicular to the sliding direction 7a of the actuating body 7 and is parallel to the placement surface 3. At this time, the interlocking mechanism 8 includes a first contact portion 8c provided on the operating body 6 and a second contact portion 8d provided on the actuating body 7 and contacting the first contact portion 8c.

[0037] Also, as shown in FIG. 12, two transfer holders 4 may be attached to a transfer device (specifically, an attachment 11 attached to the arm of the transfer device), and the two transfer holders 4, 4 may hold one object to be held 2 (in the illustrated embodiment, a support body that supports the object to be transferred by sandwiching it). In this example, on the placement surface 3, placement pins 13 are provided instead of the placement frame 12, and the object to be held 2 is supported by the placement pins 13 so as not to slide on the placement surface 3.
