The mark tube mounting device M1 can be operated by the control of the controller M12 shown in FIG. Hereinafter, FIG. 2, FIG. 3 and FIG. 6 to FIG.
The operation of the mark tube mounting device M1 will be described based on the flowcharts of FIGS. 14 to 16 with reference to FIG.
The controller M12 executes the mark tube processing control means M21 and the electric wire processing control means M22 to control the mark tube processing mechanism M111 and the electric wire processing mechanism M112 of the mark tube mounting device M1.

The electric wire processing mechanism M112 is a driven roller 36.
Is pressed against the roller 35 to start from the initial state in which the covered electric wire 28 is gripped (step 100). Further, the mark tube processing mechanism M111 also includes the roller 7,
The mark tube 2 is gripped by the driven roller 8, and the mark tube grip correction plate 11 moves up to the boundary between the mark tube grip guide hole 75 of the housing 6 and the electric wire guide path 76 toward the open housing 6, and the housing 6 Is closed and the mark tube gripping correction plate 11 is sandwiched between the initial state to start (step 100). First, the length, component position information, wire order, mark tube order, etc. for each covered electric wire are read from an external memory or the like (step 101).

When the input of data is completed, the system waits for a start input and starts when the start button is pressed (step 101). First, the process 1 shown in FIG. 16 is executed. Mark tube 2 set in guide pipe 3
However, the conveyance is started by the rollers 7 and 8. The mark tube 2 which has started to be conveyed passes through the guide pipes 3 and 4, and is inserted into the housing 6 in a closed state with the thickness of the mark tube gripping correction plate 11 left (step 10).
2). When this is detected by the sensor (mark tube detection) 21 (step 103), since the necessary amount of mark tube has already been taken in, the mark tube grip correction plate 11 stops the conveyance of the mark tube 2 (step). 104). When the sensor (for mark tube detection) 21 confirms the conveyance, the roller 7,
8 stops, the mark tube grip correction plate 11 is pulled out from the housing 6, the housing 6 is completely closed, and the mark tube is securely gripped (step 105).

Next, in order to search the cutting position where the mounting plate 24 is printed on the mark tube, the stepping motor (for the mounting plate) 23 starts moving upward (step 106), and the sensor 20 causes the cutting position. When the cutting position is detected, it stops (step 107). Next, the mark tube cutting blade 9 completely cuts the mark tube,
At the same time, the mark tube cutting blade 10 (for semi-cutting) carries out semi-cutting with one tube left (step 108). As a result, it is possible to always correct the unavoidable expansion and contraction of the mark tube, which occurs due to pre-printing work on the mark tube, mechanical conveyance in this apparatus, environmental temperature change, and the like.

Next, the mounting plate 24 is lowered to the initial position (step 109), and the guide pipe 5 is opened (step 110). Returning to FIG. 14, after this first processing 1 (step 150), the housing 6 is rotated 180 degrees (step 112), and the mounting plate 25 is transferred in the direction of the electric wire machining mechanism M112 (step 113). The housing 6 is shown in FIG.
The mark tube 2 is installed at the position of 0 and the mark tube 2 is set on the line of the electric wire processing mechanism M112. At this time, the semi-cut portion 67 of the mark tube 2 is cut into the notch on the mark tube side of the guide pipe 33 and the mark tube contact plate 56.
As a result, the mark tube 66 marked with the wire number attached to the covered wire 28 is bent into a shape close to a right angle, so that the wire does not interfere with the insertion of the wire into the mark tube.

Next, the covered electric wire 28 set in the guide pipe 29 is started to be conveyed by the driven roller 36 pressed by the air cylinder (for the driven roller) 48 and the roller 35 driven by the torque motor 57 (step 114). ,
The electric wire guide 30, the block (fixed) 43, and the block (movable) 44 are passed to the guide pipe 32 with certainty by the roller 35, the roller 37 rotating in synchronization with the driven roller 36, and the driven roller 38. The covered electric wire 28 is securely inserted into the mark tube 2 held by the housing 6 and attached by the electric wire guide path of the guide pipe 32. The mark tube 2 attached here is shown in FIG.
The mark tube 66 is engraved with the electric wire number, and the semi-cut portion 67 is attached to the electric wire number engraved mark tube 66. In the semi-cut part 67,
Wiring instruction information and the like are engraved.

Then, the covered electric wire 28 passes through the guide pipe 32 and is fed to a position where the sensor 47 incorporated in the electric wire guide block 34 detects the electric wire. When the sensor 47 senses the electric wire (step 115), the roller 35, the driven roller 36, the roller 37, and the driven roller 38 are stopped, and the conveyance of the covered electric wire 28 is stopped (step 116). Then, the air cylinder (for the driven roller) 52 presses the driven roller 40 toward the roller 39, so that the roller 39 and the driven roller 40 grip the electric wire.

Next, the housing 6 is opened (step 1
17), the mounting plate 25 is a mark tube processing mechanism M111
Direction, and the housing 6 is rotated 180 degrees with the housing 6 opened (step 118), and then the mark tube grip correction plate 11 is moved toward the opened housing 6.
When it rises to the boundary between the mark tube grip guide hole 75 of the housing 6 and the electric wire guide path 76 (step 11
9), the housing 6 is closed (step 120), and the mark tube grip correction plate 11 is sandwiched. That is, it is set in the initial position in the figure in the initial state. And
As a result, the mark tube processing mechanism M111 performs the series of operations described above regardless of the operation of the electric wire processing mechanism M112, and enters the standby state.

On the other hand, in the electric wire processing mechanism M112, after the electric wire gripping operation of the roller 39 and the driven roller 40, the driven roller 36 is separated from the roller 35 and the driven roller 38 is separated from the roller 37. Next, after the tube is fixed by the block (fixed) 43 and the block (movable) 44 (step 121), the guide pipe 32 and the guide pipe 33 are opened (step 12).
2). As a result, the covered electric wire 28 can be conveyed by the servomotor 59 with the mark tube 2 still attached.

In the electric wire processing mechanism M112 capable of conveying electric wires with the tube attached, the controller M12
When the specified amount of the electric wire is conveyed in the forward direction based on the command from the electric wire, and the electric wire's curling position passes through the roller 39 and the driven roller 40 (step 123), the guide pipe 3

4). Then, the encoder 6 attached to the servo motor 59
When the feed amount of the electric wire measured at 0 coincides with the input electric wire length data, the forward feeding of the covered electric wire 28 is stopped (step 125). Next, the driven roller 36 is pressed by the roller 35 to grip the covered electric wire 28, and the blade (fixed) 4
1. The coated electric wire 28 is cut by the blade (moving) 42,
It becomes the electric wire 63 (see FIG. 13) (step 126).

Next, the forward transport is started again (step 12
7) When the sensor 46 senses the electric wire cutting portion (step 128), the servo motor 59 is stopped and the electric wire 63 is stopped from being conveyed (step 129). After branching, the process 1 is terminated (step 151), and the mark tube processing mechanism M111 grips the mark tube 2 and stands by.
In order to incorporate the housing 6 of No. 6 into the electric wire processing mechanism M112, the housing 6 is transferred by moving the mounting plate 25 as shown in FIG. 11 (step 130 in FIG. 15), and the mark tube 2 is moved to the position shown in FIG. Set.
At this time, the semi-cut portion 69 of the mark tube 2 is bent by the notch on the mark tube side of the guide pipe 32 and the mark tube abutting plate 55 so as to be bent from the electric wire number-marked mark tube 68 attached to the rear end of the electric wire 63 to a nearly right angle. As in the case where the mark tube is attached to the tip of the electric wire, the shape is such that it does not hinder the insertion of the rear end of the electric wire 63 into the mark tube.

Next, the roller 39 and the driven roller 40 start reverse rotation, and the electric wire 63 is conveyed backward. Electric wire 6 here
The mark tube is surely attached to the rear end of step 3 (step 131). The electric wire 63 passes through the guide pipe 32, the roller 39 left open, and the roller 37 and the driven roller 38 which started reverse rotation at substantially the same speed as the driven roller 40, the block (fixed) 43, the block (movable) 44, and the sensor 45. Is detected (step 132). Sensor 4
5, the roller 39, the driven roller 40, the roller 37, and the driven roller 38 stop (step 13).
3) The electric wires are laid so that the mark tubes are not moved or fallen off (step 134).

Next, the guide pipe 32 and the guide pipe 3
3, the housing 6 is opened (step 135), and the mounting plate 25 and the housing 6 become the mark tube processing mechanism M1.
Returning to the initial position of 11 (step 136), the mark tube grip correction plate 11 faces the opened housing 6, and the mark tube grip guide hole 7 of the housing 6 is moved.
5 and the electric wire guideway 76 (step 14
3) The housing 6 is closed (step 144), the mark tube gripping correction plate 11 is sandwiched, and the mark tube processing mechanism M111 is in the initial standby state.

On the other hand, the forward transfer of the electric wire 63, which has been curled by the roller 39 and the driven roller 40, is restarted (step 137), and when the sensor 47 detects the complete discharge of the electric wire (step 138), the roller 39 and the driven roller are driven. The roller 40 stops, the forward conveyance of the electric wire 63 is completed (step 139), and the guide pipe 32 and the guide pipe 33 are closed (step 140). When the driven roller 40 is opened by the air cylinder (for the driven roller) 52 (step 141), the wire processing mechanism M is released.
112 also returns to the initial standby state. Finally, the operation control computer (not shown) is confirmed to send a signal indicating the end of the final process (step 142), and a series of operations is ended. If there is subsequent data, these steps are repeated until there is no more data.

In the above description, the outer diameter of the mark tube is 4.3.
Although the description has been given with respect to the millimeter, the inner diameter of 3.3 millimeter, and the conductor cross-sectional area of the coated electric wire of 1.25 square millimeter, it is not limited to this size. When it is desired to change the coated electric wire and the tube, the guide pipe 32, the guide pipe 33 and the housing 6 can be easily replaced, respectively. Guide pipe 2
9, the electric wire guide 30, the guide pipe 31, the electric wire guide block 34, the guide pipe 3, the guide pipe 4, the guide pipe 5, etc. do not need to be changed. Further, although the mark tube which has already been printed is applied here, a commercially available thermal head may be arranged above the guide pipe 3 for printing and mounting processing.
