Next, the operation of the mark tube mounting apparatus of the present embodiment will be described with reference to the flowcharts of FIGS. When the power is turned on to the apparatus, first, each control circuit is initialized, and the housing 14 and the tube hand 41 are respectively positioned at the home positions.
And the tube hand 41 are opened (101). Subsequently, the wire is transported until the sensor 16a detects the wire 1 (10
2) Then, the wire 1 is cut obliquely by the cutter 13 (10
3) The cut excess electric wire falls into the discharge hole 29 and is discharged to the outside.

Next, the apparatus enters a state of waiting for input of operation data from the operation unit 4 (104). When the operation data is input, the data is stored in the RAM 52 (105), and the operation of all data is completed. The work of attaching the mark tube to the electric wire is performed until (106).

In this operation, first, tube printing processing is performed.
(107) Subsequently, the delivery process of the mark tube single material 48 is performed (108). The mark tube printing process (107) will be described with reference to the flowchart of FIG. 12. First, when the data of the mark tube 2 attached to the first electric wire is sent,
(201), the mark tube is conveyed while printing on the mark tube according to the print data, and stopped when the amount of tube conveyance from the start of the printing process reaches the distance from the thermal head 32a to the tube cutter 33 (202). The tube 2 is cut (203), and an extra mark tube at the end is removed (204).

The tube discharging process (204) will be described with reference to the flowchart of FIG.
1 is closed, the mark tube single material 48 is grasped (401), and the tube hand 41 is advanced until the sensor 47 detects it (4).
02) Then, the tube hand 41 is opened (403). As a result, as shown in FIG. 8, the mark tube material 48 falls from the tube hand 41 toward the discharge hole 29 and is discharged to the outside. Next, the tube hand 41 is retracted to the home position (404), and the mark tube discharging process is completed.

Subsequently, one mark tube is transported by one tube (at this time, if there is print data, printing is performed) (205),
The mark tube 2 is cut (206). Thus, the single mark tube material 49 to be attached to the first electric wire is created.

Next, tube delivery processing (108) is performed.
Referring to the flowchart of FIG. 13, first, the tube hand 41 is closed, and the mark tube single material 48 is grasped (30).
1) The tube hand 41 is advanced to the housing 14 (302), and then the tube hand 41 is opened (303). As a result, as shown in FIG. 7, the mark tube single material 48 is placed on the set portion 14c of the housing 14. Next, when the mark tube sensor 23 of the housing 14 detects the single mark tube material 48 (304), the tube hand 41 is retracted (305), and the mark tube delivery process ends. When the mark tube single material 48 does not fall from the tube hand 41 and the sensor 23 does not detect it in step (304), the tube hand 41 is closed again.
(306), open again (303), and repeat until the tube falls.

Next, the housing 14 is closed, and the mark tube 48 is held in the set portion 14c (109). Subsequently, the electric wire 1 is transported. Electric wire 1 is guide block 12
a and the retaining press 15a, pass through the guide portion 14d of the housing 14, and are guided into the inner hole of the marker tube single piece 48, come out of the housing 14, and enter the retaining press 1.
5b, the guide block 12c, and the transport roller 10c, and when the sensor 16b detects the wire, the wire 1 is temporarily stopped (110). At this time mark tube single material 4
8 is the set portion 1 without being conveyed with the electric wire by the mark tube stopper 14e of the housing upper block 14a.
4c. Next, retaining press 1
5b is closed to form a bent portion 49 at the tip of the electric wire 1 (11).
1)

Next, the housing 14 is opened (112), and the electric wire 1 is conveyed again until its end passes the cutter 17 (1).
13) . At this time, since the upper block 14a of the housing is moving, the mark tube stopper 14e does not hinder the transfer of the mark tube, and since the lower block is not provided with a gap, the electric wire 1 and the single material of the mark tube 48 are smoothly transferred. Is done. Subsequently, the tip of the electric wire 1 is cut at a right angle by the cutter 17 (114), and a predetermined
The wire 1 is transported again to the length (115), and the rear end of the wire 1 is cut obliquely by the cutter 13 (116). After the slant cutting, the wire 1 is transported again, and the rear end of the wire 1
When the wire 1 has been transported, the transport of the electric wire 1 is stopped (117).
It is in a standby state until the next marker tube 48 attached to the rear end of the electric wire 1 is conveyed to the housing 14. The extra electric wire cut in step (114) falls into the discharge hole 29 and is discharged outside.

Subsequently, tube printing processing (118) is performed. Referring to the flow chart of FIG. 12, since it is not the first tube in this case (201), one mark tube is conveyed (at this time, if there is print data, printing is performed) (205), and the mark tube is cut off ( 206), and the microphone tube single material 48 to be next attached to the electric wire is created. Next, in the same manner as in step (108) described above, the mark tube single material 48 is conveyed to the housing 14 and tube delivery processing is performed (119).

Subsequently, the housing 14 is closed (120), and then the housing 14 is rotated by 180 ° to cope with the reverse transport of the electric wires (121). Then, the electric wires are reversely transported. When the sensor 16a detects, the reverse conveyance of the wire is stopped (122), and a stopper is formed at the rear end of the wire (12).
3) Open the housing (124).
The wire is conveyed until passing through 6b (125), the rear end of the wire is cut at a right angle by the cutter 17 (126), and the prepared wire is discharged (127). Finally, the housing 14 is rotated to return to the home position (128). The process of attaching the mark tube for one electric wire is completed. Step (1
The extra wires cut in step 26) fall into the discharge holes 29 and are discharged to the outside
