Description

[Technical field]

[0001] The present invention relates to a mark band attachment device for attaching a mark band to an electric wire. [Background technology]

[0002] For example, in electric wires used in electrical equipment requiring a large number of wires, such as distribution boards and control panels, a ring for identification called a mark band is attached to the end of each electric wire on the connection terminal side in order to prevent erroneous connection of the electric wire and to facilitate maintenance and inspection work. A ring as shown in FIG. 1 of Patent Document 1 may be used as the mark band. This mark band has a form of a split ring made of synthetic resin with a slit, and is provided with an identification mark such as a number, letter, symbol, or color to identify the electric wire. When attaching the mark band to the electric wire, the slit is pushed open and the mark band is fitted onto the electric wire through the slit portion.

[0003] In order to improve the workability when manually attaching the above-mentioned mark band to an electric wire, a mark band set as described in Patent Documents 2 and 3 is commercially available. As shown in Fig. 12a and Fig. 12b, this mark band set is configured by inserting a plurality of synthetic resin mark bands 1 into a synthetic resin support shaft 2. A convex linear guide 2a is provided on the outer periphery of the support shaft 2 along the axial direction of the support shaft 2. In addition, a contact portion 2b is provided on the tip of the support shaft 2, which has a shape that can contact the outer periphery of the electric wire 3 to which the mark band 1 is attached and 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, the mark band set is held in the hand, and the mark band 1 is pushed toward the tip of the support shaft 2 with the fingers while the contact portion 2b at the tip of the support shaft 2 is in contact with the outer periphery of the electric wire 3. Then, the mark band 2 is guided by the linear guide 2b to the contact portion 2b, and when passing through the contact portion 2b, the slit 1a is pushed open and expanded in diameter, and the mark band 2 fits onto the outer periphery of the electric wire 3 through the slit 1a. In this way, the mark band 1 is attached to the electric wire 3. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0010] 1 shows an electric wire 3 with a connection terminal, for example, a crimp terminal 4 attached to one end. In this example of the electric wire 3, a mark band 1 is attached adjacent to the crimp terminal 4, and a mark tube 5 is attached adjacent to the mark band 1. For example, the mark band 1 is a color band having a color determined in advance according to the phase of an AC circuit or the polarity of a DC circuit to which the electric wire 3 is connected. The mark tube 5 displays information such as the device, line number, and terminal number to which the electric wire 3 is connected on its outer surface using numbers, letters, symbols, two-dimensional barcodes, etc. Although not shown in the figure, the other end of the electric wire 3 has a similar configuration.

[0011] The mark band 1 is a ring having the same shape as the mark band 1 shown in Fig. 12a and Fig. 12b. That is, the mark band 1 has a form of a split ring made of synthetic resin with a slit 1a, and when an external force is applied in a direction to expand the slit 1a, the diameter expands, and when the external force is removed, the diameter contracts and returns to the natural state. The inner diameter of the mark band 1 in the natural state is smaller than the outer diameter (including the insulating coating) of the electric wire 3 to be attached. In this embodiment, mark bands 1 of four colors (for example, blue, red, black, and yellow) that are predetermined in accordance with the phase of the AC circuit and the polarity of the DC circuit are prepared, and for each color, multiple mark bands 1 of the same color are inserted into the support shaft 2 to form a mark band set A. This mark band set A may be specially designed and manufactured, but in this embodiment, a commercially available mark band set product as shown in Fig. 12a and Fig. 12b is used as the mark band set A.

[0012] 2 shows an electric wire 3 before the mark band 1 and the crimp terminal 4 are attached. The insulating coating of the most end 3a of the end of the electric wire 3 is removed in order to connect the crimp terminal 4. Then, a mark tube 5 is attached to the center of the electric wire 3 with a predetermined space from the most end 3a from which the insulating coating has been removed. The mark band attachment device according to this embodiment automatically attaches a mark band 1 to the end of the electric wire 3 (the portion between the most end 3a and the mark tube 5) that is supplied in the manner shown in FIG. 2.

[0013] FIG. 3 is a schematic diagram of the mark band attachment device according to this embodiment, seen from above.

[0014] The mark band attachment device of this embodiment is composed mainly of a mark band set A formed by inserting multiple mark bands 1 of the same color into a support shaft 2, a positioning table serving as a base, for example an index table (rotary table) 6, a mark band set holding section 7 (7a, 7b) which 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 described below (the second pressing member 10 is not shown in FIG. 3). The index table 6 is rotationally driven and controlled in one or both directions (counterclockwise in the example shown in FIG. 3) by a control section, not shown.

[0015] In this embodiment, a structure including the mark band set A, the mark band set holding parts 7 (7a, 7b) and the first pressing member 9 is defined as a unit U, and 12 unit units U1 to U12 having the same structure are arranged at equal intervals in the circumferential direction on the upper surface of the index table 6, facing the radial direction of the index table 6. For the 12 unit units U1 to U12, for example, the mark band 1 of the mark band set A in the unit units U1 to U3 is blue, the mark band 1 of the mark band set A in the unit units U4 to U6 is red, the mark band 1 of the mark band set A in the unit units U7 to U9 is black, and the mark band 1 of the mark band set A in the unit units U9 to U12 is yellow.

[0016] The mark band receiving pin 8 is attached to a movable base 12 (illustration of the movable base 12 is omitted in FIG. 3) described later, and is normally located at a predetermined position on the outer periphery of the index table 6 and a predetermined distance above the upper surface of the index table 6 with its axis facing the radial direction of the index table 6. In this embodiment, the position of this mark band receiving pin 8 is referred to as a first position P1. A control unit (not shown) of the index table 6 selects one unit U holding a 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 U is positioned opposite the mark band receiving pin 8 located at the first position P1.

[0017] FIG. 4a is a schematic diagram seen from above showing a state where the selected unit U is moved to a position facing the mark band receiving pin 8 located at the first position P1 by the rotation drive control of the index table 6. The mark band set holding portion 7 (7a, 7b) is attached to a base 11 fixed at a predetermined position on the upper surface of the index table 6, and includes a first holding portion 7a that holds the contact portion 2b at the tip side of the support shaft 2 so as to grip it from both sides, and a second holding portion 7b that holds the outer periphery of the mark band 1 at the rear end side of the support shaft 2 so as to grip it from both sides. The first holding portion 7a holds the support shaft 2 in an immovable state, and the second holding portion 7b holds the mark band 1 in a state where it can move 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 approximately 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 shape capable of contacting an end face of the mark band 1, is attached to a base 11 in a state in which it can slide along the support shaft 2 of the mark band set A, and is driven to slide by a driving means such as a linear actuator (not shown). The first pressing member 9 is located closer to the tip of the support shaft 2 than the multiple mark bands 1 in the mark band set A, and is driven to slide toward the rear end of the support shaft 2, thereby pressing the multiple mark bands 1 toward the rear end of the support shaft 2 and pushing out a predetermined number of mark bands 1, for example one mark band 1, from the rear end of the support shaft 2, as shown in FIG. 4(b).

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

[0020] FIG. 5 is a schematic side view of the selected unit U when it has moved to a position facing the mark band receiving pin 8 located at the first position P1 (as shown in FIG. 4b). The mark band receiving pin 8 is fixed to a 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 movable along the axial direction of the mark band receiving pin 8, a lower movable part 12b movable in the vertical direction, and a drive part (not shown) that operates the upper movable part 12a and the lower movable part 12b in each of the above directions. In this embodiment, a guide member 13, which will be described later, is attached to the upper movable part 12a. The guide member 13 has a role of guiding the end of the electric wire 3 to which the mark band 1 is to be attached to the inner peripheral part of the rear end of the enlarged diameter part 8b of the mark band receiving pin 8.

[0021] The second pressing member 10 attached to the mounting member 14 is fixedly disposed 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 of the support shaft 2 in the manner shown in FIG. 4(b) and received by the tip 8a of the mark band receiving pin 8 located at the first position P1, the upper movable part 12a moves in the axial direction of the mark band receiving pin 8 so as to move away from the index table 6, and the lower movable part 12b moves downward. Due to the operation of the movable base 12, the mark band receiving pin 8 that has received the mark band 1 and the guide member 13 move in the axial direction and downward, and as shown in FIG. 6, the mark band receiving pin 8 moves to a predetermined position where its tip 8a faces the second pressing member 10 so as to avoid interference with the second pressing member 10. In this embodiment, the position of the 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 3 held by an electric wire insertion unit, for example, a robot hand 15, waits. The robot hand 15 has a function of gripping an end of the electric wire 3 and moving the end 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 guide member 13 a predetermined distance toward the second pressing member 10, and 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 the state in which the mark band receiving pin 8, guide member 13, and the end of the electric wire 3 have each moved the above-mentioned predetermined distances.

[0023] 8a shows the state (as 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 the state (as viewed from above) in which the mark band receiving pin 8 and the guide member 13 have moved the above-mentioned predetermined distance from the second position P2 shown in FIG. 6 toward the second pressing member 10 and reached the position shown in FIG. 7. The second pressing member 10 has a shape that can abut against the end face of the mark band 1, and 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 by the tip 8a of the mark band receiving pin 8 is pressed by the second pressing member 10 and transferred to the expanded diameter portion 8b. The mark band 1 transferred to the expanded diameter portion 8b is expanded in diameter by the expanded diameter portion 8b to 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 are temporarily stopped when the mark band 1 is pressed by the second pressing member 10 and moves to the rear end of the enlarged diameter portion 8b.

[0024] FIG. 9a shows a state in which the mark band 1 has been pressed by the second pressing member 10 and moved to the rear end of the expanded diameter portion 8b (the state shown in FIGS. 7 and 8b), and FIG. 9b shows a state in which the end of the wire 3 has moved a predetermined distance toward the mark band receiving pin 8 by operation of the robot hand 15 and has been inserted into the inner peripheral portion of the rear end of the expanded diameter portion 8b of the mark band receiving pin 8 via the guide member 13. The guide member 13 is disposed so as to face the rear end of the expanded diameter portion 8b of the mark band receiving pin 8, and the inner peripheral portion of the guide member 13 is provided with a conical guide surface 13a whose diameter gradually increases from the front end to the rear end of the guide member 13. The guide surface 13a The front and rear ends are both open, and the front end of the guide surface 13a has an inner diameter that fits the outer diameter (including the insulating coating) of the electric wire 3 and faces the rear end of the enlarged diameter portion 8b of the mark band receiving pin 8. By the operation of the robot hand 15, the end of the electric wire 3 moving toward the mark band receiving pin 8 enters the guide surface 13a from the rear end of the guide surface 13a of the guide member 13, and while being guided by the guide surface 13a, it passes through the front end of the guide surface 13a and is inserted into the inner peripheral portion of the rear end of the enlarged diameter portion 8b. As shown in FIG. 9b, the robot hand 15 stops once when the end of the electric wire 3 is inserted into the inner peripheral portion of the rear end of the enlarged diameter portion 8b by a predetermined distance.

[0025] 10, the guide member 13 is composed of left and right divided bodies 13b, 13c divided along the axis of the guide surface 13a, and at least one of the divided bodies 13b, 13c is movable in the left and right direction so as to open the guide surface 13a. When the end of the electric wire 3 is inserted into the inner peripheral part of the rear end part of the enlarged diameter part 8b by a predetermined distance and the operation of the robot hand 15 is stopped, the divided bodies 13b, 13c are operated to open the guide surface 13a in the left and right direction.

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

[0027] This completes the attachment of the mark band 1 to one end of the electric wire 3. The electric wire 3 with the mark band 1 attached to one end is pulled out from the inner peripheral part of the rear end of the expanded diameter part 8b of the mark band receiving pin 8 by the operation of the robot hand 15, and moved to a predetermined location. The attachment of the mark band 1 to the other end of the electric wire 3 is performed in the same manner as above. In this way, the electric wire 3 with the mark bands 1 attached to both ends is sent to a process of crimping (connecting) the crimp terminals 4.

[0028] In the above embodiment, the second pressing member 10 is fixedly arranged and the mark band 1 is pressed by the second pressing member 10 as the mark band receiving pin 8 moves toward the second pressing member 10 along its axial direction; however, the mark band 1 may also be pressed by the second pressing member 10 moving toward the mark band receiving pin 8 along the axial direction of the mark band receiving pin 8, or by both the mark band receiving pin 8 and the second pressing member 10 moving toward each other along the axial direction of the mark band receiving pin 8.

[0029] In addition, when moving the mark band receiving pin 8 between the first position P1 where it receives the mark band 1 pushed out from the rear end of the support shaft 2 by the first pressing member 9, and the second position P2 opposite the second pressing member 10, in the above embodiment, the movable table 12 is operated in the axial direction of the mark band receiving pin 8 and in the vertical direction. However, for example, if the second pressing member 10 is positioned directly below or directly above the outer periphery of the index table 6, the movable table 12 can be operated in the vertical direction to move the mark band receiving pin 8 between the first position P1 and the second position P2 without interfering with the second pressing member 10. Furthermore, for example, when the second pressing member 10 is positioned at a position horizontally perpendicular to the axial 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 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 (opposite the second pressing member 10).

[0030] In the above embodiment, the index table (rotary table) 6 is used as the positioning table, but a positioning table capable of positioning in one axis (X axis) or two axes (X axis and Y axis) may be used instead of the index table 6. In this case, a plurality of units U (U1 to U12) are arranged on the upper surface of the positioning table at a predetermined interval in the X axis direction, each facing the Y axis direction of 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 a selected unit U is positioned to face 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 arranged at a position perpendicular to the axial direction of the mark band receiving pin 8 located at the first position P1, and the movable base 12 is configured to be movable in the axial direction and the rotational direction of the mark band receiving pin 8, and the mark band receiving pin 8 can be moved between the first position P1 and the second position P2 by operating the movable base 12 90 degrees in the rotational direction.

[0031] Also, the operation of inserting the end of the electric wire 3 into the inner peripheral portion of the rear end of the enlarged diameter portion 8b of the mark band receiving pin 8 by operating 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, the robot hand 15 is operated in the state shown in FIG. 6 to insert the end of the electric wire 3 into the inner peripheral portion of the rear end of the enlarged diameter portion 8b of the mark band receiving pin 8, and then the movable base 12 is operated to move the mark band receiving pin 8 and the guide member 13 toward the second pressing member 10, and at the same time, the robot hand 15 is operated to move the end of the electric wire 3 toward the second pressing member 10 following (synchronizing) with the movement of the mark band receiving pin 8 and the guide member 13. This leads to the state shown in FIG. 7. [Explanation of symbols]
