Description

Technical Field

[0001] The present invention relates to a mark band mounting device for mounting a mark band on an electric wire.

Background Art

[0002] For example, in electric wires used in electrical equipment that requires a large number of wirings such as switchboards and control panels, in order to eliminate incorrect connection of the electric wires and facilitate maintenance and inspection work, an identification ring called a mark band is attached to the end portion on the connection terminal side of each electric wire. As the mark band, a ring body as described in FIG. 1 of Patent Document 1 may be used. This mark band has a form of a split ring made of synthetic resin provided with a slit, and is provided with identification displays such as numbers, letters, symbols, colors, etc. for identifying the electric wire. When mounting the mark band on the electric wire, the slit is expanded and fitted onto the electric wire from the slit portion.

[0003] In order to improve the workability when manually attaching the above-described mark band to an electric wire, a set of mark bands as described in Patent Documents 2 and 3 is commercially available. As shown in FIGS. 12a and 12b, this set of mark bands is configured by inserting a plurality of synthetic resin mark bands 1 into a synthetic resin support shaft 2. On the outer periphery of the support shaft 2, a convex linear guide 2a is provided along the axial direction of the support shaft 2. Further, at the tip of the support shaft 2, a contact portion 2b is provided which has a shape that can contact the outer periphery of the electric wire 3 to which the mark band 1 is to be attached and which has a shape that gradually expands toward the tip. The mark band 1 is inserted into the support shaft 2 with its slit 1a portion aligned with the linear guide 2a. As shown in FIG. 13, when attaching the mark band 1 to the electric wire 3, hold the set of mark bands in the hand, and while bringing the contact portion 2b at the tip of the support shaft 2 into contact with the outer periphery of the electric wire 3, push the mark band 1 with a finger toward the tip side of the support shaft 2. Then, the mark band 2 is guided by the linear guide 2b and advances to the contact portion 2b. When passing through the contact portion 2b, the slit 1a is pushed open and expands in diameter, and fits into the outer periphery of the electric wire 3 from the slit 1a portion. Thereby, the mark band 1 is attached to the electric wire 3.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010] FIG. 1 shows an electric wire 3 having a connection terminal, for example, a crimp terminal 4, attached to one end portion. In the electric wire 3 of this example, a mark band 1 is attached adjacent to the crimp terminal 4, and further, a mark tube 5 is attached adjacent to the mark band 1. For example, the mark band 1 is a color band having a predetermined color according to the phase of an AC circuit or the polarity of a DC circuit to which the electric wire 3 is connected. Further, the mark tube 5 displays information such as the equipment to which the electric wire 3 is connected, the wire number, the terminal number, etc. on its outer peripheral surface by numbers, letters, symbols, two-dimensional barcodes, etc. Although illustration is omitted, the other end portion of the electric wire 3 has the same configuration.

[0011] The marking band 1 is a ring body in the same form as the marking band 1 shown in FIGS. 12a and 12b. That is, the marking band 1 has the form of a split ring made of synthetic resin provided with a slit 1a. When an external force is applied in the direction of expanding the slit 1a, the diameter expands, and when this external force disappears, the diameter contracts and returns to the natural state. The inner diameter of the marking band 1 in the natural state is smaller than the outer diameter of the wire 3 (including the insulation coating) to be mounted. In this embodiment, four-color (for example, blue, red, black, yellow) marking bands 1 whose colors are determined in advance according to the phase of the AC circuit, the polarity of the DC circuit, etc. are prepared. For each color, a plurality of marking bands 1 of the same color are inserted into the support shaft 2 to form a marking band set A. This marking band set A may be specially designed and manufactured. However, in this embodiment, a commercially available marking band set product as shown in FIGS. 12a and 12b is used as the marking band set A.

[0012] FIG. 2 shows the wire 3 before attaching the marking band 1 and the crimp terminal 4. The end of the wire 3 has the insulation coating removed at the outermost end 3a in order to connect the crimp terminal 4. Then, a marking tube 5 is mounted with a predetermined space left from the outermost end 3a where the insulation coating has been removed toward the center side of the wire 3. The marking band mounting device according to this embodiment automatically mounts the marking band 1 on the end of the wire 3 (the portion between the outermost end 3a and the marking tube 5) supplied in the manner shown in FIG. 2.

[0013] FIG. 3 is a schematic view of the marking band mounting device according to this embodiment as viewed from above.

[0014] The mark band mounting device of this embodiment is composed of a mark band set A configured by inserting a plurality of mark bands 1 of the same color into a support shaft 2, a positioning table as a base, for example, an index table (rotary table) 6, a mark band set holding portion 7 (7a, 7b) that holds the mark band set A on the upper surface side of the index table 6, a mark band receiving pin 8, a first pressing member 9, and a second pressing member 10 (not shown in FIG. 3) described later as main elements. The index table 6 is rotationally driven and controlled in one direction or two directions (counterclockwise in the example shown in FIG. 3) by a control unit (not shown).

[0015] In this embodiment, a structure including the mark band set A, the mark band set holding portion 7 (7a, 7b), and the first pressing member 9 is used as a unit unit U, and twelve unit units U1 to U12 of the same structure are arranged at equal intervals in the circumferential direction on the upper surface of the index table 6, each facing radially outward from the index table 6. For the twelve unit units U1 to U12, for example, the mark bands 1 of the mark band set A in the unit units U1 to U3 are blue, those in the unit units U4 to U6 are red, those in the unit units U7 to U9 are black, and those in the unit units U9 to U12 are yellow.

[0016] The mark band receiving pin 8 is attached to a movable base 12 (not shown in FIG. 3) described later, and is always positioned at a predetermined position on the outer peripheral side of the index table 6 and a predetermined dimension above the upper surface of the index table 6 with its axis facing radially outward from the index table 6. In this embodiment, the position of this mark band receiving pin 8 is referred to as the first position P1. The control unit (not shown) of the index table 6 selects one unit unit U that holds the mark band 1 (mark band set A) of a predetermined color to be attached to the electric wire 3 from among the unit units U1 to U12, and rotationally drives and controls the index table 6 so that the unit unit U comes to a position facing the mark band receiving pin 8 located at the first position P1.

[0017] Figure 4a is a schematic view from above of a state in which the selected unit unit U has moved to a position facing the mark band receiving pin 8 located at the first position P1 by the rotational drive control of the index table 6. The mark band set holding portion 7 (7a, 7b) is attached to a pedestal 11 fixed at a predetermined position on the upper surface of the index table 6, and holds the portion of the contact portion 2b on both sides so as to grip it on the front end side of the support shaft 2. The first holding portion 7a and the second holding portion 7b that holds the outer peripheral portion of the mark band 1 on both sides on the rear end side of the support shaft 2. The first holding portion 7a holds the support shaft 2 in a non-movable state, and the second holding portion 7b holds the mark band 1 in a state movable in the axial direction of the support shaft 2. The axis of the support rod 2 of the mark band set A held by the mark band set holding portion 7 (7a, 7b) is coaxial (including substantially coaxial) with the axis of the mark band receiving pin 8 located at the first position P1.

[0018] The first pressing member 9 has a form that can contact the end surface of the mark band 1, is attached to the pedestal 11 in a state slidable along the support shaft 2 of the mark band set A, and is slidably driven by a driving means such as a linear actuator (not shown). The first pressing member 9 is located on the front end side of the support shaft 2 with respect to the plurality of mark bands 1 in the mark band set A, and is slidably driven to the rear end side of the support shaft 2, so that as shown in FIG. 4(b), the plurality of mark bands 1 are pressed to the rear end portion side of the support shaft 2, and a predetermined number, for example, one mark band 1 is pushed out from the rear end portion of the support shaft 2.

[0019] The mark band receiving pin 8 is formed in a hollow shaft shape, and has a tapered conical tubular tip portion 8a having a smaller diameter than the inner diameter of the mark band 1 in the natural state, and a cylindrical enlarged diameter portion 8b that is smoothly connected to the tip portion 8a and has a larger diameter than the inner diameter of the mark band 1 in the natural state. The mark band 1 pushed out from the rear end portion of the support shaft 2 by the first pressing member 9 is received by the tapered conical tubular tip portion 8a of the mark band receiving pin 8.

[0020] FIG. 5 is a schematic side view of the state in which the selected unit unit U has moved to a position facing the mark band receiving pin 8 located at the first position P1 (the state shown in FIG. 4b). The mark band receiving pin 8 is fixed to the movable base 12 and is normally located at the first position P1. The movable base 12 is composed of an upper movable part 12a to which the mark band receiving pin 8 is attached and which is movable along the axial direction of the mark band receiving pin 8, a lower movable part 12b which is movable in the vertical direction, and a driving part (not shown) for operating the upper movable part 12a and the lower movable part 12b in the respective directions. Further, in this embodiment, a guide member 13 described later is attached to the upper movable part 12a. The guide member 13 has a role of guiding the end portion of the electric wire 3 to which the mark band 1 is to be attached to the inner peripheral portion of the rear end portion of the enlarged diameter portion 8b of the mark band receiving pin 8.

[0021] A second pressing member 10 attached to the attachment member 14 is fixedly arranged below the mark band receiving pin 8 located at the first position P1. When the mark band 1 is pushed out from the rear end portion of the support shaft 2 in the manner shown in FIG. 4(b) and received by the tip portion 8a of the mark band receiving pin 8 located at the first position P1, the upper movable part 12a operates in the axial direction of the mark band receiving pin 8 so as to move away from the index table 6, and further the lower movable part 12b operates downward. Due to the operation of the movable base 12, the mark band receiving pin 8 and the guide member 13 that have received the mark band 1 move in the axial direction and the downward direction described above. As shown in FIG. 6, the tip portion 8a of the mark band receiving pin 8 moves to a predetermined position facing the second pressing member 10 so as to avoid interference with the second pressing member 10. In this embodiment, the position of this mark band receiving pin 8 is referred to as the second position P2. Behind the mark band receiving pin 8 and the guide member 13 that have moved to the second position P2, an electric wire insertion portion, for example, the electric wire 3 held by the robot hand 15, waits. The robot hand 15 has a function of gripping the end portion of the electric wire 3 and moving the end portion of the electric wire 3 in the axial direction of the mark band receiving pin 8.

[0022] From the state shown in FIG. 6, the upper movable part 12a operates in the axial direction of the mark band receiving pin 8 to move the mark band receiving pin 8 and the guide member 13 a predetermined distance toward the second pressing member 10, and further the robot hand 15 operates to move the end of the electric wire 3 a predetermined distance toward the mark band receiving pin 8. FIG. 7 shows a state in which the mark band receiving pin 8 and the guide member 13 and the end of the electric wire 3 have each moved by the above-mentioned predetermined distance.

[0023] FIG. 8a shows a state (viewed from above) in which the mark band receiving pin 8 and the guide member 13 are located at the second position P2 shown in FIG. 6, and FIG. 8b shows a state (viewed from above) in which the mark band receiving pin 8 and the guide member 13 have moved a predetermined distance toward the second pressing member 10 from the second position P2 shown in FIG. 6 and reached the position shown in FIG. 7. The second pressing member 10 has a form capable of abutting against the end face of the mark band 1. When the mark band receiving pin 8 and the guide member 13 move from the second position P2 shown in FIG. 8a toward the second pressing member 10, the mark band 1 received at the tip 8a of the mark band receiving pin 8 is pressed by the second pressing member 10 and transferred to the enlarged diameter portion 8b. The mark band 1 transferred to the enlarged diameter portion 8b is enlarged in diameter at the enlarged diameter portion 8b to have a diameter larger than the outer diameter of the electric wire 3 (including the insulating coating). As shown in FIG. 8b, the mark band receiving pin 8 and the guide member 13 temporarily stop when the mark band 1 is pressed by the second pressing member 10 and moves to the rear end portion of the enlarged diameter portion 8b.

[0024] Fig. 9a shows the state where the marking band 1 is pressed against the second pressing member 10 and moves to the rear end portion of the diameter-expanded portion 8b (the state shown in Figs. 7 and 8b). Fig. 9b shows the state where, due to the operation of the robot hand 15, the end portion of the electric wire 3 moves a predetermined distance toward the side of the marking band receiving pin 8 and is inserted into the inner peripheral portion of the rear end portion of the diameter-expanded portion 8b of the marking band receiving pin 8 through the guide member 13. The guide member 13 is arranged to face the rear end portion of the diameter-expanded portion 8b of the marking band receiving pin 8. A conical guide surface 13a that gradually expands in diameter from the front end to the rear end is provided on the inner peripheral portion of the guide member 13. The front end portion and the rear end portion of the guide surface 13a are each open. The front end portion of the guide surface 13a has an inner diameter that conforms to the outer diameter (including the insulating coating) of the electric wire 3 and faces the rear end portion of the diameter-expanded portion 8b of the marking band receiving pin 8. Due to the operation of the robot hand 15, the end portion of the electric wire 3 that moves toward the side of the marking band receiving pin 8 enters the guide surface 13a from the rear end portion of the guide surface 13a of the guide member 13, and while being guided by the guide surface 13a, passes through the front end portion of the guide surface 13a and is inserted into the inner peripheral portion of the rear end portion of the diameter-expanded portion 8b. As shown in Fig. 9b, the robot hand 15 temporarily stops when the end portion of the electric wire 3 is inserted into the inner peripheral portion of the rear end portion of the diameter-expanded portion 8b by a predetermined dimension.

[0025] As shown in Fig. 10, the guide member 13 is composed of left and right divided bodies 13b and 13c that are divided along the axis of the guide surface 13a, and at least one of the divided bodies 13b and 13c is movable in the left-right direction so as to open the guide surface 13a. When the end portion of the electric wire 3 is inserted into the inner peripheral portion of the rear end portion of the diameter-expanded portion 8b by a predetermined dimension and the operation of the robot hand 15 stops, the divided bodies 13b and 13c operate to open the guide surface 13a in the left-right direction.

[0026] Thereafter, the upper movable part 12a operates in the axial direction of the mark band receiving pin 8. As shown in FIG. 11, the mark band receiving pin 8 and the guide member 13 further move a predetermined distance to the side of the second pressing member 10 (the left side in the figure). As a result, the mark band 1 that has moved to the rear end portion of the diameter-expanded portion 8b is pressed by the second pressing member 10, pushed out from the rear end portion of the diameter-expanded portion 8b, and transferred onto the outer peripheral portion of the end portion of the electric wire 3. Then, the mark band 1 transferred onto the outer peripheral portion of the end portion of the electric wire 3 contracts in diameter due to the elastic restoring force and fits onto the outer peripheral portion of the end portion of the electric wire 3.

[0027] Thus, the attachment of the mark band 1 to one end portion of the electric wire 3 is completed. The electric wire 3 with the mark band 1 attached to one end portion is pulled out from the inner peripheral portion of the rear end portion of the diameter-expanded portion 8b of the mark band receiving pin 8 by the operation of the robot hand 15 and moves to a predetermined position. The attachment of the mark band 1 to the other end portion of the electric wire 3 is also performed in the same manner as above. In this way, the electric wire 3 with the mark band 1 attached to both end portions is sent to the process of crimping (connecting) the crimp terminal 4.

[0028] In the above embodiment, the second pressing member 10 is fixedly arranged, and the mark band receiving pin 8 moves to the side of the second pressing member 10 along its axial direction, so that the mark band 1 is pressed by the second pressing member 10. However, the second pressing member 10 may move to the side of the mark band receiving pin 8 along the axial direction of the mark band receiving pin 8, or both the mark band receiving pin 8 and the second pressing member 10 may move to each other's sides along the axial direction of the mark band receiving pin 8, so that the mark band 1 is pressed by the second pressing member 10.

[0029] Also, when moving the mark band receiving pin 8 between a first position P1 for receiving the mark band 1 pushed out from the rear end portion of the support shaft 2 by the first pressing member 9 and a second position P2 facing the second pressing member 10, in the above-described embodiment, the movable table 12 is operated in the axial direction and the vertical direction of the mark band receiving pin 8. However, for example, when the second pressing member 10 is disposed directly below or directly above the outer peripheral portion of the index table 6, by operating the movable table 12 in the vertical direction, the mark band receiving pin 8 can be moved between the first position P1 and the second position P2 without interfering with the second pressing member 10. Further, for example, when the second pressing member 10 is disposed at a position orthogonal to the axial direction and the horizontal direction of the mark band receiving pin 8 located at the first position P1, the movable table 12 is configured to be movable in the axial direction and the rotational direction of the mark band receiving pin 8, and by operating the movable table 12 90 degrees in the rotational direction, the mark band receiving pin 8 can be moved between the first position P1 and the second position P2 (facing the second pressing member 10).

[0030] Also, in the above-described embodiment, the index table (rotary table) 6 is used as the positioning table. However, instead of the index table 6, a positioning table that can be positioned in the one-axis (X-axis) or two-axis (X-axis and Y-axis) direction may be used. In this case, a plurality of unit units U (U1 to U12) are arranged on the upper surface of the positioning table at predetermined intervals in the X-axis direction with their respective Y-axis directions facing the positioning table, and the positioning table is driven and controlled in the X-axis direction so that the support shaft 2 of the mark band set A of the selected one unit unit U comes to a position facing the tip portion 8a of the mark band receiving pin 8 located at the first position P1. For example, the second pressing member 10 is disposed at a position orthogonal to the axial direction and the horizontal direction of the mark band receiving pin 8 located at the first position P1, the movable table 12 is configured to be movable in the axial direction and the rotational direction of the mark band receiving pin 8, and by operating the movable table 12 90 degrees in the rotational direction, the mark band receiving pin 8 can be moved between the first position P1 and the second position P2.

[0031] Also, the operation of inserting the end of the electric wire 3 into the inner peripheral portion of the rear end portion of the enlarged diameter portion 8b of the mark band receiving pin 8 by the operation of the robot hand 15 may be performed when the mark band receiving pin 8 moves to the second position P2 (the state shown in FIG. 6). In this case, in the state shown in FIG. 6, the robot hand 15 is operated, and after the end of the electric wire 3 is inserted into the inner peripheral portion of the rear end portion of the enlarged diameter portion 8b of the mark band receiving pin 8, by the operation of the movable table 12, the mark band receiving pin 8 and the guide member 13 are moved to the side of the second pressing member 10. At the same time, by the operation of the robot hand 15, the end of the electric wire 3 follows (synchronizes with) the movement of the mark band receiving pin 8 and the guide member 13 and is moved to the side of the second pressing member 10. Thereby, the state shown in FIG. 7 is reached.
