Devices for automation are also known (for example, Patent Documents 1 and 2).
JP-A-8-140233 Japanese Patent Laid-Open No. 9-282957

  When such a conventional technique is used, crimp terminals and markers can be attached to the terminals of each electric wire, but only the wiring symbol of each electric wire is displayed on the marker. There is a problem that the instruction information is not sufficient, there is a limit to improving the efficiency of wiring work, and there is a high risk of erroneous wiring. Generally, the wiring symbol of each electric wire is merely a symbol on the electric circuit indicated in the electric wiring diagram, and does not specifically indicate the connection destination of each electric wire.

  Therefore, in view of the problems of the prior art, the object of the present invention is to display information indicating the connection destination of each electric wire (hereinafter referred to as wiring information) by combining the main sheet and the sub sheet, thereby facilitating the wiring work. It is an object of the present invention to provide an apparatus for mounting a display tag for wiring information that can be highly efficient.

  The configuration of the present invention for achieving such an object includes a pair of left and right opening / closing arms that adsorb and hold a main sheet and a sub sheet constituting a wiring information display tag of an electric wire. The gist is to attach the main sheet and the sub-sheet together and attach them to the electric wire by closing them so as to sandwich them.

  The open / close arm can be provided with an open / close guide for guiding the electric wire to an appropriate position when the main sheet and the sub sheet are bonded together.

  Moreover, the removal member which removes the main sheet | seat and sub sheet | seat adhering to an opening / closing arm can be provided.

  The display tag for electric wire wiring information includes a main sheet and a sub sheet, and the main sheet for displaying the wiring information of the electric wire is attached to the electric wire by being bonded together with the sub sheet. Therefore, the operator can easily connect the electric wire to the correct connection destination according to the instruction of the wiring information, and minimize the chance of taking excessive time or miswiring to find the connection destination. be able to. In addition, the main sheet and the sub sheet may be removed from the electric wire and discarded together with the main sheet by breaking the sub sheet when the connection of the electric wires is completed.

  The main sheet is transported in an orderly manner on the carrier tape by applying pressure-sensitive adhesive to the entire back side, and the necessary wiring information is printed and displayed by the printing unit, and the wires are sandwiched. When the sheet is bonded to the sub-sheet, the central portion adheres to the coating of the electric wire, so that it does not inadvertently move in the longitudinal direction of the electric wire. On the other hand, by applying a pressure sensitive adhesive to both ends on the back side, the secondary sheet can be similarly transported in alignment on a carrier tape for transport, and the main sheet is turned inside when breaking. Even if it is bent, there is no risk of excessively strong adhesion to the wire coating. As long as there is no hindrance to the printing operation by the printing unit, the pressure-sensitive adhesive can be applied to both ends of the back side of the main sheet and applied to the entire back side of the sub sheet. The sheet side can be broken and removed from the wire at once.

  According to the configuration of the present invention, the pair of left and right open / close arms are opened at 180 °, for example, the main sheet and the sub sheet are adsorbed and held on the lower surfaces of the respective front end portions, and are closed downward so as to sandwich the electric wire. The sheet and the sub-sheet can be bonded together and attached to the electric wire, and the connection destination of the electric wire can be specifically instructed to the operator via the wiring information on the main sheet. However, the open / close arm is, for example, opened at 180 ° to attract the main sheet and the sub sheet on the carrier tape, the peeling position to move forward with the advance of the carrier sheet and peel the main sheet and the sub sheet from the carrier tape, Further forward and backward, the standby position to stand up above the electric wire, close down downward toward the lower electric wire, and move back and forth so as to reversibly move between the attachment positions where the main seat and sub-sheet are attached to the electric wire It shall drive in a direction and an up-down direction.

  The open / close guide attached to the open / close arm guides the electric wire to an appropriate position when the open / close arm is closed, and correctly attaches the main sheet and the sub sheet to the electric wire. In addition, when one or both of the main sheet and the sub sheet cannot be attached to the electric wire, the removing member mechanically removes the main sheet and the sub sheet that remain attached to the open / close arm from the open / close arm, thereby The main sheet and the sub sheet can be adsorbed to the opening / closing arm without any trouble.

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

  The display tag for wiring information of electric wires is composed of a main sheet Sa and a sub sheet Sb (FIG. 1).

  The electric wire W is, for example, a vinyl-coated electric wire. The electric wire W is subjected to terminal processing by attaching, for example, a tube-shaped marker M displaying a wiring symbol Ma and a crimp terminal T with an insulating sheath T1 to each terminal.

  The main sheet Sa is made of paper, for example, and the wiring information Wa of one end of the electric wire W is printed and displayed on the surface. However, the illustrated wiring information Wa = AB01D02 indicates that the electric wire W should be connected to, for example, the terminal D02 of the instrument number AB01. Since the wiring information Wa is instruction information for wiring work for the worker, it can be changed to any other display format. The sub sheet Sb is made of paper of the same shape and size as the main sheet Sa.

  A pressure sensitive adhesive N is applied to the entire back surface of the main sheet Sa (FIG. 2A). Moreover, the pressure sensitive adhesive N is apply | coated to the back surface side both ends of subsheet Sb, respectively (the same figure). Thus, the main sheet Sa and the sub sheet Sb can be attached to the electric wire W as a display tag for wiring information of the electric wire by attaching them together so as to sandwich the electric wire W (two-dot chain line in FIG. 1, FIG. 2 ( B)). The main sheet Sa and the sub-sheet Sb mounted on the electric wire W in this way are bonded to the coating of the electric wire W via the pressure-sensitive adhesive N on the back surface side of the main sheet Sa. There is no possibility of inadvertent movement in the longitudinal direction of the electric wire W. Further, the main sheet Sa and the sub-sheet Sb on the electric wire W are bent with fingers so that the main sheet Sa becomes inside when the wiring of the electric wire W is completed (in the direction of the arrow in FIG. 2C), and the main sheet Sa is left as it is. By pulling to the side (in the direction of the arrow in FIG. 4D), the outer sub-sheet Sb can be broken, removed from the electric wire W together with the main sheet Sa, and discarded.

  The blank main sheet Sa before printing the wiring information Wa can be prepared by sticking it in a line on the carrier tape C for transportation through the pressure-sensitive adhesive N in an equal pitch and winding it up in a roll. (FIG. 2 (E)). Further, the main sheet Sa unwinds the carrier tape C and advances it intermittently along a guide (not shown) (in the direction of the arrow C1 in FIG. 2 (F)), and necessary wiring information Wa by a printing unit (not shown). Is printed (arrow C2 position in the figure). Thereafter, a suction pad (not shown) is pressed from the upper surface to be sucked to the suction pad (position of arrow C3 in the figure), and is advanced together with the suction pad to bend the carrier tape C downward at an acute angle, whereby the main sheet Sa is brought into contact with the carrier tape. It can be easily peeled off from C and only the main sheet Sa can be transported to the mounting position for the electric wire W together with the suction pad (in the direction of arrow C4 in the figure).

  The sub-sheet Sb can be handled in the same manner. However, the sub sheet Sb does not need to print the wiring information Wa. That is, the main sheet Sa and the sub sheet Sb may be conveyed one by one to the mounting position with respect to the electric wire W, and bonded together to be mounted on the electric wire W.

  The mounting device for the display tag for wiring information of the electric wire includes a pair of left and right symmetrical opening and closing arms 11 and 11 for the main sheet Sa and the sub sheet Sb (FIGS. 3 and 4). However, FIG. 4 shows the opening / closing arm 11 for the sub-sheet Sb, but the opening / closing arm 11 of the main sheet Sa is also configured in the same manner.

  The front end portion of each open / close arm 11 is partially widened rearward, and a groove 11a is formed across the open / close arm 11 on the lower surface of the widened portion. Further, suction pads 12 and 12 for adsorbing the main sheet Sa or the sub-sheet Sb are attached to both sides of the groove 11a on the lower half of the lower surface of the widened portion, and connectors 12a corresponding to the respective suction pads 12 are provided on the upper surface. , 12a are mounted. Header holes 12b and 12b with blind plugs 12c communicating with the respective connectors 12a are formed in the widened portion of the opening / closing arm 11, and small holes reaching the lower surface of the suction pad 12 are formed in each header hole 12b. 12d, 12d, ... are formed in communication. Each suction pad 12 is formed of an appropriate elastic body such as silicone rubber, and each connector 12a is connected to a negative pressure source (not shown).

  Therefore, the main sheet Sa and the sub-sheet Sb can be sucked and held on the lower surfaces of the suction pads 12 and 12 so as to cross the grooves 11a of the corresponding opening and closing arms 11, respectively. An optical sensor 11d is mounted between the connectors 12a and 12a on each open / close arm 11 through a hole 11e that opens in the top surface of the groove 11a. The optical sensor 11d is attached to the suction pads 12 and 12. The adsorbed main sheet Sa or sub sheet Sb can be detected.

  The open / close arms 11 and 11 can be opened and closed by a common air-driven actuator 13 (FIGS. 3 and 5). That is, the open / close arms 11 and 11 are horizontally opened at 180 ° to adsorb the main sheet Sa and the sub sheet Sb (solid lines in FIGS. 3 and 5) and are closed downward via the actuator 13 (arrows in FIG. 3). 5, the main sheet Sa and the sub sheet Sb can be integrally attached to the electric wire W so as to sandwich the electric wire W therebetween. However, the terminal-processed electric wire W is supplied to an appropriate position below the open / close arms 11 and 11 via a guide rod Wb that moves in parallel toward the lower side of the open / close arms 11 and 11 (see FIG. 3). When the open / close arms 11 and 11 are closed, they are stored in a square area 11b formed by grooves 11a and 11a between the suction pads 12 and 12. The actuator 13 is provided with stoppers 11c and 11c in order to define an opening limit when the opening and closing arms 11 and 11 are opened at 180 °.

  A pair of opening and closing guides 14 and 14 are assembled in front of and behind the opening and closing arms 11 and 11, respectively. The bases of the opening / closing guides 14 and 14 of each set are rotatably connected to the opening and closing arms 11 and 11, and the distal ends thereof are connected to each other so as to be rotatable. Therefore, the open / close guides 14 and 14 are lowered while the open / close arms 11 and 11 are closed and the downward leading ends are closed (two-dot chain lines and one-dot chain lines in FIG. 5), and the electric wires W are correctly inserted into the area 11b together with the guide rods Wb. Can guide.

  The actuator 13 is assembled to the lower end of the movable base 17 through a slider 16 attached to one side surface and a slide rail 16a combined with the slider 16 so as to be movable back and forth (FIGS. 5 and 6). A rack 15 parallel to the slider 16 and the slide rail 16 a is attached to the actuator 13, and a pinion 15 a at the shaft end of the motor 15 b on the moving base 17 is engaged with the rack 15.

  On the other hand, a slider 17 a is fixed to the back side of the moving base 17, and the slider 17 a is combined with a vertical slide rail 17 b on the fixed base 18. On the fixed base 18, a double rod air cylinder 19 is mounted vertically via a bracket 19a. The downward rod of the air cylinder 19 is connected to the bracket 19a, and the upward rod is a bracket. It connects with the movement base 17 via 19b. Therefore, the open / close arms 11 and 11 connected to the actuator 13 can be driven in three stages up and down via the air cylinder 19 and can be arbitrarily moved back and forth via the motor 15b. However, the opening / closing arm 11 and the suction pad 12 indicated by the thin lines in FIG. 6 illustrate a plurality of typical movement positions.

  Behind the open / close arms 11 and 11, a pair of left and right boat-shaped guide blocks 21 are provided for advancing and bending the carrier tapes C and C for the main sheet Sa and the sub sheet Sb wound in a roll shape at an acute angle. 21 is disposed (FIGS. 7 and 8). 7A and 7B are a side view and a front view, respectively, and FIG. 8 is an enlarged perspective view of a main part showing the guide block 21 on the main sheet Sa side and the printing unit 22 thereabove. It is.

  A rod 21b is rotatably mounted on the front end of the guide block 21 via left and right brackets 21a and 21a in order to bend the carrier tape C downward at an acute angle. The printing unit 22 is protected by a protective cover 22a, and is mounted on a movable bracket 22c that can move up and down via a slider 22d and a slide rail 22e together with a rear pressure roller 22b. An auxiliary bracket 23a is attached to the moving bracket 22c, and the auxiliary bracket 23a is engaged with and disengaged from a catch 23 that is fixed downward to the fixed base 23b, so that the print unit 22 on the moving bracket 22c is moved to an upper standby position ( 7A) and the operation position (two-dot chain line in FIG. 7) for printing predetermined wiring information Wa on the main sheet Sa on the carrier tape C on the guide block 21. Can do.

  When the printing unit 22 is set to the operating position, the pressure roller 22b is pressed against the carrier tape C on the guide block 21 via a spring 22f that urges the moving bracket 22c downward. However, the printing unit 22 is omitted from the moving bracket 22c on the sub-sheet Sb side. Each moving bracket 22c on the main sheet Sa side and the sub sheet Sb side is assembled with an optical sensor 22g for detecting the main sheet Sa or the sub sheet Sb on the carrier tape C traveling on the guide block 21. ing.

  Accordingly, the carrier tapes C on the main sheet Sa side and the sub sheet Sb side are supplied from the rear side to the upper surface of the corresponding guide block 21 via the supply roller 25, and face downward via the rod 21 b at the front end of the guide block 21. Can be bent at an acute angle and wound around a winding roller (not shown). Further, the main sheet Sa or the sub sheet Sb on the carrier tape C is detected by the corresponding optical sensor 22g, so that the wiring information Wa can be correctly printed on the main sheet Sa via the printing unit 22. However, the carrier tapes C and C for the main sheet Sa and the sub sheet Sb are synchronized with each other, and the pitches of the main sheet Sa and the sub sheet Sb are intermittently advanced on the guide block 21.

  A plate-shaped removal member 31 is disposed below the guide blocks 21 and 21 (FIGS. 7 and 9). The front end of the removal member 31 is formed with claws 31a and 31a that are branched in a fork shape and bent upward, and the rear connection piece 31b is connected to the rod of the rear air cylinder 31c. The air cylinder 31c is mounted on a fixed base plate 31d via a bracket 31e.

  The claws 31a and 31a protrude upward in front of the left and right guide blocks 21 and 21 (FIGS. 7 and 8), and the lower surfaces of the guide blocks 21 have auxiliary claws 32a corresponding to the claws 31a. The material 32 is fixed. Therefore, when the removal member 31 is driven back and forth by expanding and contracting the air cylinder 31c, the claws 31a and 31a are in front of the guide block 21, respectively, at the pinch positions where they closely contact the claws 32a of the auxiliary material 32 (see FIG. 7A). It can be moved back and forth between the solid line, FIG. 8) and a standby position (two-dot chain line in FIG. 7A) that moves forward of the claw 32a. However, the front part of the removal member 31 is guided by inserting the guide pins 21c, 21c on the lower surface of each guide block 21 into the left and right elongated holes 31f, 31f (FIG. 9), and the rear part of the removal member 31 is The slider 31h on the removing member 31 and the slide rail 31g on the lower surface of the base plate 31d are combined to guide (FIG. 7).

  The operation of the mounting device for the display tag for wiring information of the electric wire is as follows.

２１上を進行するキャリヤテープＣ、Ｃ上の主シートＳa 、副シートＳb の各１ピッチ相当だけ印字ユニット２２の前方の位置である。また、このときの除去部材３１は、待機位置に待機させる。 First, the open / close arms 11 and 11 are opened at 180 °, and the guides immediately in front of the print unit 22

21 is a position in front of the printing unit 22 corresponding to one pitch of each of the main sheet Sa and the sub-sheet Sb on the carrier tape C and C traveling on the C. Moreover, the removal member 31 at this time is made to wait at a standby position.

  On the other hand, based on a signal from an electric wire supply device (not shown), the printing unit 22 uses the guide information Wb, the wiring information Wa, Wa,... Of the electric wires W, W, which are sequentially supplied to the front of the open / close arms 11, 11. Since printing is sequentially performed on the main sheets Sa, Sa... On the tape C, the carrier tapes C and C for the main sheet Sa and the sub sheet Sb are intermittently advanced in synchronism with each other. Therefore, by synchronizing the operation timings of the printing unit 22 and the electric wire supply device, the wiring information Wa printed on the main sheet Sa immediately below the open / close arms 11 and 11 at the preparation position and the actual open / close arms 11 and 11 The correspondence with the electric wire W supplied forward can be adapted.

こで、開閉アーム１１、１１は、それぞれの先端部の吸着パッド１２、１２を介し、ガイドブロック２１、２１上の主シートＳa 、副シートＳb を吸着して保持することができる。なお、各吸着パッド１２の下面には、図示しない負圧源からの負圧を作用させるものとする。 The main sheet Sa on which the wiring information Wa is printed and the corresponding sub-sheet Sb are in the preparation position.

Here, the open / close arms 11 and 11 can suck and hold the main sheet Sa and the sub sheet Sb on the guide blocks 21 and 21 via the suction pads 12 and 12 at the respective leading ends. It should be noted that a negative pressure from a negative pressure source (not shown) is applied to the lower surface of each suction pad 12.

対応するガイドブロック２１の前端のロッド２１ｂを介して鋭角に屈曲するから、開閉アーム１１、１１に吸着して保持されている主シートＳa 、副シートＳb は、対応するキャリヤテープＣから容易に剥がすことができる。そこで、開閉アーム１１、１１は、剥離位置に留まることなく、さらに斜め上向きに前進することにより、キャリヤテープＣ、Ｃから剥がした主シートＳa 、副シートＳb を保持して、除去部材３１の爪３１ａ、３１ａの

シートＳb を装着すべき電線Ｗは、ガイドロッドＷb を介して開閉アーム１１、１１の下方の適位置に供給される（図１０の実線、二点鎖線）。 Subsequently, when the main sheet Sa and the sub sheet Sb move forward by one pitch, the open / close arms 11 and 11 are moved forward to the peeling position of the front ends of the guide blocks 21 and 21 in synchronization therewith.

Since it bends at an acute angle via the rod 21b at the front end of the corresponding guide block 21, the main sheet Sa and the sub sheet Sb adsorbed and held by the open / close arms 11 and 11 are easily peeled off from the corresponding carrier tape C. be able to. Therefore, the open / close arms 11 and 11 do not stay at the peeling position, but further advance obliquely upward to hold the main sheet Sa and the sub sheet Sb peeled off from the carrier tapes C and C, and the claw of the removing member 31. 31a, 31a

The electric wire W to which the sheet Sb is to be mounted is supplied to an appropriate position below the open / close arms 11 and 11 via the guide rod Wb (solid line, two-dot chain line in FIG. 10).

と（図１０の一点鎖線）、電線Ｗを挟むようにして主シートＳa 、副シートＳb を貼り合わせ、電線Ｗに装着することができる。そこで、各吸着パッド１２に対する負圧を停止し

b の進出を待ち、以下同様の装着動作を繰り返せばよい。

(The one-dot chain line in FIG. 10), the main sheet Sa and the sub sheet Sb can be bonded together so as to sandwich the electric wire W, and can be attached to the electric wire W. Therefore, the negative pressure on each suction pad 12 is stopped.

Wait for b to advance, and then repeat the same mounting operation.

きの除去部材３１は、その待機位置にあり、爪３１ａ、３１ａが補助材３２、３２の爪３２ａ、３２ａに対して十分に開いている（図１１の二点鎖線）。 In the above series of operations, if the attachment of the main sheet Sa and the sub sheet Sb to the electric wire W fails, the open / close arms 11 and 11 are in the preparation position with the main sheet Sa or the sub sheet Sb attached to the lower surface of the suction pads 12 and 12. Return to. Therefore, when the main sheet Sa or the sub sheet Sb that has failed to be mounted is detected by the optical sensors 11d, 11d on the open / close arms 11, 11, the open / close arms 11, 11 are located above the claws 31a, 31a of the removal member 31. Standby position for removal

The mushroom removal member 31 is in its standby position, and the claws 31a, 31a are sufficiently open to the claws 32a, 32a of the auxiliary members 32, 32 (two-dot chain line in FIG. 11).

位置に後退させて爪３１ａ、３１ａを爪３２ａ、３２ａに密着させると（図１１の二点鎖線、実線）、各組の吸着パッド１２、１２の下面の主シートＳa または副シートＳb を爪３１ａ、３２ａの間に折り縮めるようにして挟み込み、吸着パッド１２、１２の下面から機械的に除去することができる。なお、このときの各組の爪３１ａ、３２ａは、各開閉アーム１１の吸着パッド１２、１２の間の溝１１ａに対応するものとし、爪３１ａの上端は、溝１１ａ内を開閉アーム１１の前方から後方に通り抜けるものとする。したがって、そ

When the claws 31a and 31a are brought into close contact with the claws 32a and 32a (the two-dot chain line and the solid line in FIG. 11), the main sheet Sa or the sub-sheet Sb on the lower surface of each of the suction pads 12 and 12 is moved to the claws 31a , 32a so as to be folded between them, and mechanically removed from the lower surfaces of the suction pads 12, 12. In this case, each pair of claws 31a and 32a corresponds to the groove 11a between the suction pads 12 and 12 of each opening and closing arm 11, and the upper end of the claw 31a extends in the groove 11a to the front of the opening and closing arm 11.
