Further, as shown in FIG. 4 and FIG. 8, the mark tube unit 29a is set up vertically along a step with the guide portion 14e of the set portion 14c of the housing 14, and the mark tube unit is provided. When the material 37 is dropped onto the setting portion 14c, the mark tube single material 37 is moved to the guide portion 14e.
A tube guide plate 36 is provided to guide the end of the mark tube single piece 37 so as not to protrude from the side and to be positioned close to the guide portion 14e side.

At the tip of the swinging plate 32, a mark tube 3 placed in the concave portion 28 a of the tube hand 28 is provided.
7 is provided (a hole 28b is formed above the concave portion of the tube hand).

The sensors 34 and 35 detect the position of the air cylinder, and the sensor 34
Is at the home position, and the sensor 35 detects that the concave portion 28a of the tube hand 28 is at the position of the housing 14.

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 this apparatus, first, each control circuit is initialized, the housing 14 and the tube hand 28 are respectively located at their home positions, and the housing 14 is opened (101). Subsequently, the electric wire 1 is transported to the cutter 13 and cut obliquely by the cutter 13 (102). The surplus cut electric wires fall into the discharge holes 21 and are discharged to the outside.

Next, the operation waits for input of operation data from the operation unit 4 (103), and when the operation data is input, this data is stored in the data storage means (RAM) (104). The work of attaching the mark tube to the electric wire is performed until the end of the process (105).

First, predetermined characters and the like are printed on the tube 2, and then are conveyed to the concave portion 28 a of the tube hand 28, and cut into a predetermined length by the tube cutter 25.
(106). At this time, as shown in the enlarged view of the tube transport section when the mark tube is cut in FIG. 9, the solenoid 31 is activated and the mark tube is pressed by the projection 32a of the swinging plate 32. Is prevented from moving.

The tube delivery process (107) will be described with reference to the flowchart of FIG. 12. First, as shown in FIGS. 5 and 8, the tube material 37 is formed by the concave portion 28 a of the tube hand 28 and the tube receiving portion 29 a of the sliding member 29. It is supported so as to be held from the side and from below, so that, for example, even if the mark tube single material 37 is deformed as if it is crushed vertically long, or if it is softened by heat, it does not fall on the way.

[0026] (moving to the left in FIG. 5) the tubes hand 28 when Ru is advanced until Hauujingu 14 in this state (2
01) , as shown in FIGS. 6 and 10, the protrusion 29b of the sliding member 29 comes into contact with the lower block 14b of the housing 14, and the movement of the sliding member 29 is stopped against the spring 30. When the member 28 is completely advanced, the lower portion of the concave portion 28a is opened, and the mark tube material 3
7 is dropped and placed on the set portion 14c of the housing 14.

Next, when the mark tube sensor 20 of the housing 14 detects the mark tube material 37 (20
2) The tube hand 28 is retracted (203), and the mark tube delivery process ends.

Here, when the sensor 20 does not detect the mark tube single material 37, for example, the mark tube single material 3
When the cylinder 7 is deformed as if squashed laterally and does not fall down in contact with the inner wall of the recess 28a, the solenoid 31 is activated (204).
As shown in FIG. 6 and FIG.
Forcibly drop a mark tube single material 37 extruded tube single member 37 from the recess 28a of the tube hand 28 2a
Let it down.

Subsequently, the presence or absence of the mark tube single material 37 in the setting section 14c is again checked (205), and when the mark tube single material 37 is detected, the tube hand 28 is retracted (203). When the mark tube is not detected, it is determined that the tube has not been successfully delivered, and the operation is interrupted (206).

Here, a state where the mark tube single material 37 is dropped will be described. When the sliding member 29 comes into contact with the lower block 14b of the housing 14 and moves with respect to the tube hand 28, the tube guide plate 36 comes to face the concave portion 28a of the tube hand 28,
7 falls along the tube guide plate 36.

[0031] Therefore dropped or marked tubes single member 37 is obliquely for some time signature, even so moves toward the guide portion 14e side of the electric wire insertion side of the setting portion 14C when bounces off a rebound of the drop, 10 As shown in (2), the tube guide plate 36 guides the mark tube single material 37 so as to fall straight down to the set portion 14C, so that the mark tube single material 37 and the guide portion 14e can be prevented from overlapping.

Next, the housing 14 is closed, and the mark tube single member 37 is gripped in the set portion 14c (108).
The electric wire 1 is conveyed again, and the electric wire 1 passes through the guide block 12a, passes through the guide portion 14e of the housing 14, passes through the inner hole of the marker tube single piece 37, passes through the housing 14, and passes through the guide block 12c. Once passed, it is temporarily stopped, then the retaining air cylinder 15 is activated, and the piston 15a is pushed down to bend the electric wire 1 together with the tube single material 37, and the bent portion 3 of the tube single material retaining is prevented.
8 is formed (109).

Next, the housing 14 is opened (110), the electric wire 1 is conveyed again, and the tip of the electric wire 1 is cut at a right angle by the cutter 16 (111). Cut the rear end of the wire 1 diagonally (112)
. After the diagonal cutting, the wire 1 is transported until the rear end passes through the housing 14, and the standby state is set until the next marker tube material 37 attached to the rear end of the wire 1 is transported to the housing 14 (113).

Subsequently, tube printing and cutting processing (114) of the mark tube single material 37 attached to the rear end is performed,
Next, in the same manner as in step (107) described above, the rear end mark tube material 37 is placed on the housing 14 (1).
15).

Subsequently, the housing 14 is closed, and the housing 14 is rotated by 180 ° to cope with the reverse conveyance of the electric wire (116), and then the electric wire 1 is conveyed in the reverse direction. Is stopped, and the air cylinder 15 is started to form a stopper at the rear end of the electric wire (117).
.

The open housing 14 After retaining process is (118), conveying the electric wire 1 in the positive direction, the rear end of the wire 1 is perpendicularly cut by the cutter 16 (119), discharging to the outside of the apparatus this < Finally, the housing 14 is rotated to return to the home position (121), and the process of attaching the mark tube for one wire is completed, and the process for the next wire is performed.

In the above-described embodiment, the mark tube mounting device for the electric wire including the tube printing portion is disclosed. However, a single mark tube material is prepared in advance by another device, and a plurality of the mark tubes are stocked. Mark from inside
The single tube material may be sequentially conveyed to the mark tube gripping means by the mark tube conveying means .
