2. Description of the Related Art In order to facilitate the subsequent processing of marker tubes obtained by marking with a tube marking machine or the like and cutting each marking portion, and to facilitate the quantity control of these marker tubes, A technique has been proposed in which a marker tube is sequentially attached to an attaching tape at intervals in the longitudinal direction (for example, JP-A-63-288751 and JP-A-6-19170).
No. 9 and Japanese Patent Laid-Open No. 6-199464).

On the other hand, for example, when the terminals of the electric wire are attached near the terminals of the electric wire and each end of the electric wire is connected to a corresponding terminal of another device, the terminals to be connected to each other can be easily associated with each other. A marker tube is put on so that it can be removed. In this case, the two marker tubes that are put on both ends of one electric wire have the same marker marking and are handled as a set.

In the prior art, a set of these marker tubes was processed by affixing the two tubes constituting the set side by side to a sticking tape in order with a space therebetween. That is, two marker tubes are pasted side by side on a long sticking tape, and this side by side is set as one set, and a plurality of marker tubes to be another set are similarly set in the next region in the longitudinal direction of the sticking tape. They were pasted side by side. The two marker tubes, which are each set on the sticking tape, are peeled off from the sticking tape one after another and used by covering them near the terminals of the electric wires.

In this method, however, the two marker tubes to be a set are separately attached to the attaching tape, so that the efficiency of the attaching operation is low, and the marker tubes are not used for the work such as covering these wires with the electric wire. Since each one is peeled off from the attached tape and processed, the subsequent processing of the marker tubes is troublesome and there is a possibility that two marker tubes to be set may be lost.

[0006]

One of the problems to be solved by the present invention is to provide a marker tube treatment method for attaching a marker tube so that two or more marker tubes forming a set can be easily handled. To do.

Another problem to be solved by the present invention is that the marker tube on the adhesive tape can be easily peeled off, so that the subsequent processing can be carried out efficiently and the tube to be set is lost. The purpose is to provide a marker tube treatment method that does not occur.

Another problem to be solved by the present invention is to provide a marker tube processing apparatus for attaching a marker tube so that two or more marker tubes forming a set can be easily handled. .

Still another problem to be solved by the present invention is that the marker tube on the adhesive tape can be easily peeled off, so that the subsequent processing can be performed efficiently and the tube to be set is lost. It is to provide a marker tube processing device which does not do.

[0010]

A first basic problem solving means of the present invention is to form a plurality of short marker tubes by marking long tubes at intervals and cutting at each marking interval. Then, attach these short marker tubes to the long adhesive tape at intervals in the longitudinal direction of the adhesive tape, and cut the long tubes by inserting the cutter into the long tube placed on the cutting table. In the method of treating a marker tube performed, a long tube is marked to form a first marked tube section, and then the first marked tube section and a subsequent tube section are halved on a cutting table. First to do
And the subsequent tube section is marked to form a second marked tube section
Second step of completely cutting the marked tube part and the subsequent tube part on a cutting table, and a third step of applying the set of the first and second marked tube parts to a sticking tape And a fourth step of intermittently feeding the sticking tape to the sticking area after the third step.
And a marker tube treatment method.

In the first means for solving the problems, two or more first marked tube portions are continuously formed,
During this first the marked tube partial cross means that they can be half cut.

The second basic problem solving means of the present invention is as follows.
Tube marking means for marking long tubes at intervals, and tube cutting means for cutting the long tubes marked by the tube marking means at each marking interval to form a plurality of short marker tubes, and these And a tube sticking means for sticking the short marker tube of the long sticker tape on the long sticking tape at intervals in the longitudinal direction of the sticking tape, and the tube cutting means is a cutting table on which the long tube is placed and a cutting table on this cutting board. In the marker tube processing device consisting of a cutter for cutting a long tube, the tube cutting means is configured so that the long tube can be switched between a fully cut state and a half cut state, and the tube attaching means is Completely cut by the tube cutting means and separated from the subsequent tube part However, a plurality of marker tubes, which are connected to each other at the half-cut portion, are pressed and pasted onto the pasting tape.The tube pasting mechanism and the tape is intermittently fed to the pasting area every time the long tube is fully cut. Another object of the present invention is to provide a marker tube processing device characterized by comprising a tape feeding mechanism.

In the second means for solving the problem , a tube cutting / pasting interlocking means for interlocking the tube pasting mechanism of the tube pasting means and the pasting tape feeding mechanism with the descending operation of the cutter of the tube cutting means can be further provided. This tube cutting / pasting interlocking means does not interlock with the tube cutting means and the tube pasting means in the half-cutting mode of the tube cutting means, but interlocks the tube cutting means with the tube pasting means in the full cutting mode of the tube cutting means. Is configured.

In this way, a plurality of adjacent tube portions to be the respective marker tubes are cut in half, and then the adjacent marker tubes and the subsequent tube portions are completely cut to form a set of marker tubes. If you attach two or more tube parts that should be connected in half cut state to the adhesive tape, the efficiency of the attaching work will be improved, and the marker tube will be used as a whole set in the process of covering these wires with the wires. Since it is peeled off from the adhesive tape and processed, the subsequent processing of the marker tube is easy, and since two or more tube parts that form a set are continuous at the half cut part, these can be done before attaching the marker tube. There is no risk of losing the tube part.

Further, the feeding and pasting operation of the sticking tape is prevented from being performed without disconnecting the tube cutting means in the half cutting mode of the tube cutting means, and in the tube cutting means in the full cutting mode of the tube cutting means. With the interlocking operation, the tape attaching means can be driven by utilizing the operation of the tube cutting means, and thus the tube attaching means can be easily formed with a simple structure.

A pair of feeding wheels 80, 8 sandwiched to feed
The tape feeding section 82 including 0 '. One feeding wheel 80 is a gear-shaped driving wheel that engages with the upper surface that is the adhesive surface of the adhesive tape 4, and the other feeding wheel 80 '.
Is a rubber driven wheel that engages with the lower surface that is the non-adhesive surface of the adhesive tape 4.

The tape feeding section 82 is a segment gear 8 that rotates together with the pivot arm 72 of the tube attaching mechanism 62.
4 and a drive gear 86 meshing with the segment gear 84 and a driven gear 88 meshing with the drive gear 86,
The driven gear 88 is connected to a gear-shaped feed wheel 80 via a one-way clutch 90.

The pivot arm 72, as shown in FIG.
When pushed down in the clockwise direction, the segment gear 84 also rotates in the same direction, and this rotation causes the driven gear 88 to rotate in the clockwise direction via the drive gear 86. However, the driven gear 88
Since the one-way clutch 90 is in the unlocked state for rotation in this direction, the one-way clutch 90 is not transmitted to the gear-shaped feeding wheel 80, and therefore the adhesive tape 4 is not fed. .

On the other hand, when the pivot arm 72 is raised in the counterclockwise direction by the spring 71 as shown in FIG. 13, the segment gear 84 also rotates in the same direction, and this rotation is driven by the drive gear 86. Rotate 88 counterclockwise.
Since the one-way clutch 90 is locked against the rotation of the driven gear 88 in this direction, the gear-shaped feed wheel 8 is provided.
0 also rotates counterclockwise, so that the adhesive tape 4 is fed.

In this way, the pair of feeding wheels 80, 8
When 0 ′ rotates, the adhesive tape 4 is fed while being sandwiched between these feeding wheels 80, 80 ′, but the feeding wheel 80 engaging with the adhesive surface is a gear-shaped driving wheel. The adhesive tape 4 can be reliably fed without adhering to the adhesive surface. The feeding pitch is set according to the angle at which the feeding wheel 80, which is the driving wheel, rotates during one feeding operation, but a detailed description thereof will be omitted.

Further, as shown in FIGS. 11, 14 and 15, the tube attaching mechanism 6 of the tube attaching means 18 is provided.
2 and the adhesive tape feeding mechanism 64 to the tube cutting means 1
Tube cutting that is interlocked with the descending movement of the cutter 30 of 6
A sticking interlocking means 92 is further provided. The tube cutting / pasting interlocking means 92 is the tube cutting means 16
In the half cut mode, the tube cutting means 16 and the tube attaching means 18 are not interlocked, but the tube cutting means 16
In the full cut mode, the tube cutting means 16 and the tube attaching means 18 are configured to interlock with each other.

In the illustrated embodiment, the tube cutting / pasting interlocking means 92 is the cutter 3 of the tube cutting means 16.
In the half-cutting mode of the tube cutting means 16, the interlocking arm 94 supported by the cutter arm 52 holding 0 and the interlocking arm 94 releases the linkage of the tube attaching means 18 to the tube attaching mechanism 62 and the tape feeding mechanism 64. In the full cut mode of the tube cutting means 16, the interlocking arm 94 includes an interlocking arm switching mechanism 96 for switching the position of the interlocking arm 94 so that the interlocking arm 94 is linked to the tube attaching mechanism 62 and the tape feeding mechanism 64 of the tube attaching means 18. ing.

The interlocking arm 94 is, as shown in FIGS. 4, 8 and 9, a bracket 98 of the cutter arm 52 (see FIGS. 8 and 9) so as to interlock with the lowering operation of the cutter 30 of the tube cutting means 16. It is rotatably supported by a pivot 100. Also, this interlocking arm 94
Regardless of its position, the groove 52a of the cutter arm 52 is always
Has an engagement plate piece 94a which is slightly wider so as to be engaged with (see FIGS. 4 and 6 to 9).
Depending on the pivotal position of the interlocking arm 94, it engages with the pressing roller 74 of the tube adhering means 18 (see FIG. 15) or disengages from the pressing roller 74 (see FIG. 14).

As shown in FIGS. 3, 7, 14 and 15, the interlocking arm switching mechanism 96 comprises a switching solenoid 102 attached to the frame 20, and the armature 102a of this solenoid 102 is the armature 102a of the interlocking arm 94. The ring-shaped free end (the end opposite to the side having the engaging plate piece 94a) is connected with play. In this play, the free end of the interlocking arm 94 makes an arc motion despite the armature 102a of the solenoid 102 making a linear motion, so that the linear motion of the armature 102a does not hinder the arc motion of the interlocking arm 94. It is a play of a degree.

In this way, when the solenoid 102 of the interlocking arm switching mechanism 96 is excited in one direction, as shown in FIG.
As shown in FIG. 4, since the interlocking arm 94 is biased in the counterclockwise direction in FIG. 14, the interlocking arm 94 is disengaged from the pressing roller 74 of the tube attaching means 18 and the solenoid 102 is excited in the other direction. As shown, the interlocking arm 94
Becomes a position where it is urged in the clockwise direction to engage with the pressing roller 74 of the tube attaching means 18, so that the cutter arm 52 and the pressing roller 74 interlock with each other.

Next, the marker tube processing method of the present invention will be described in the order of operation. As shown in FIG. 1, the thermal head 12 of the marking means 14 is applied to the portion of the long tube 1 to be marked via the marking tape 3. A series of markings (marking corresponding to one marker tube) is made on the portion of the long tube 1 to be marked by being pressed. During the marking operation of the thermal head 12, the long tubes 1 are sequentially fed by the tube feeding means 26, so that the long tubes 1 are marked in the longitudinal direction. At this time, the marking tape 3
Is also fed so that a new marking tape portion is always located in the marking area.

When a series of markings are made and the thermal head 12 is raised, the elongated tube 1 is advanced by the operation of the tube feeding means 26 along with the first series of marked tube sections 1A1 which are continuous with it. Then, the subsequent tube portion to be marked is transferred to the marking area.

Next, the thermal head 12 descends again and the following series of markings are applied to the tube portion in the marking area, and the following marked tube portion 1A is marked.
2 is formed. This second series of markings
It usually has the same marking as the first series of marking markings (marker markings). 1st marked tube part 1A1 and 2nd marked tube part 1A
2 constitutes a set to constitute one set of marker tubes 2. As can be seen from FIG. 1, in this case, the portion to be cut (the portion corresponding to the marked tube portion 1A2 after marking) between the first marked tube portion 1A1 and its subsequent portion is on the cutting table 28. Is located in the cutting area (area having the cutter 30).

During the second marking,
The tube cutting means 16 includes a first marked tube portion 1A1 and a second marked tube portion 1A2.
The space between and is cut in half (see FIGS. 10B and 10C). As shown in FIG. 9, the armature 38a of the bidirectional solenoid 38 of the base drive mechanism 36 is displaced to the right as shown in FIG. 9, and the connecting arm 42 is swung counterclockwise to move the movable base portion 34. Is opened with respect to the fixed base portion 32. As already described with reference to FIGS. 10B and 10C, in the state where the base portions 32 and 34 hold the gap G and open,
Even if the cutter 30 descends until it hits the cutting table 28, the lower part 1a ′ of the tube portion 1A on the cutting table 28 escapes into the gap G between the table parts 32 and 34 and remains uncut (half cut part). ) 1a is formed and thus tube 1
A remains continuous on both sides of the uncut portion.

When the tube portions 1A1 and 1A2 are cut in half, as shown in FIG. 14, the armature 102a of the solenoid 102 of the interlocking arm switching mechanism 96 of the tube attaching means 18 extends to interlock the arm 9 with each other.
4 swings counterclockwise to the position where the cutter arm 52 of the tube cutting means 16 and the pivot arm 72 of the tube attaching means 18 are not interlocked. Therefore, even if the cutter arm 52 descends to cut the tube portions 1A1 and 1A2 in half, the pivot arm 72 of the tube attaching means 18 does not descend and the tube attaching means 18 does not operate. .

After the second series of marking and half-cutting is completed, the thermal head 12 rises again, while the long tube 1 moves forward together with the marked tube portions 1A1 and 1A2 which are still continuous with it. , Transfer the subsequent tube portion to be marked to the marking area. In this way, the portion to be cut between the second marked tube portion 1A2 and its subsequent portion is located on the cutting table 28 in the cutting area, and the marked tube portions 1A1 and 1A2 are attached to the attachment area. Located in.

The thermal head 12 is then lowered again to make the first series of markings of the next set on the tube section in the marking area, during which the cutter 30 of the tube cutting means 16 is now the first. Second in the set
A complete cut is made between the first marked tube portion 1A2 and the subsequent tube portion (see FIG. 10 (A)). As shown in FIG. 8, the armature 38a of the bidirectional solenoid 38 of the platform drive mechanism 36 is displaced to the left as shown in FIG. 8, and the connecting arm 42 is swung clockwise to move the movable platform portion 34. It is performed by closing the fixed base portion 32. As already described with reference to FIG. 10 (A), the base portion 3
In the state in which 2, 34 are closed, the long tube portion 1A placed thereon is cut until the cutter 30 abuts on the cutting table 28, and the entire cross section thereof is cut and cut. Thus, there is a disconnect between the first set of second marked tube section 1A2 and the subsequent tube section.

When the long tube 1 is completely cut,
The armature 102a of the solenoid 102 of the interlocking arm switching mechanism 96 retracts, the interlocking arm 94 swings clockwise, and the cutter arm 5 of the tube cutting means 16 moves.
2 and the pivot arm 72 of the tube attaching means 18 are brought into the interlocking position. Therefore, when the cutter arm 52 of the cutter driving mechanism 48 is lowered by the cam 60 in order to completely cut between the marked tube portion 1A2 and the subsequent tube portion also in the second time, the interlocking arm 94,
The tube pressing member 68 via the pressing roller 74.
Is lowered, the marker tube 2 is attached to the tape 4
It is attached on top (see FIG. 2). As can be seen from FIG. 17, when the marker tube 2 is attached so that the half cut portion 1a is located on the sticking tape 4, the marker tube 2 is prevented from dripping at the half cut portion 1a. Therefore, it is preferable for storage management.

The interlocking arm 94 is at the interlocking position, the cutter arm 52 presses the tube pressing member 68 through the pressing roller 74, and the pressing roller 74 is pressed.
The pivoting arm 72, which holds the arrow, is also pushed down in the clockwise direction in FIG. Therefore, as described above, the driven gear 88 is rotated clockwise through the segment gear 84 and the drive gear 86 of the tape feeding mechanism 64, but the one-way clutch 90 is used.
Due to the unlocked state, the transmission tape 80 is not transmitted to the gear-shaped feeding wheel 80, and therefore the adhesive tape 4 is not fed.

On the other hand, when the cutting operation of the tube cutting means 16 is completed and the cutter arm 52 is released from the cam 60, the cutter arm 52 is lifted by the spring 54. Therefore, the pivot arm 72 is also shown in FIG. Like spring 7
1 raises counterclockwise. Therefore, the driven gear 88 is rotated counterclockwise via the segment gear 84 and the drive gear 86. This time, the gear-shaped feed wheel 80 is rotated counterclockwise due to the locked state of the one-way clutch 90. , The adhesive tape 4 is fed at a predetermined pitch. In this way, the new adhesive tape portion waits in the adhesive area for applying the next set of marker tubes 2.

By repeating the above operation, as shown in FIG. 2, a large number of marker tubes 2 (a set of marked tube portions 1A1 and 1A2) are attached to the tape 4.
It is pasted on the top with a space.

In the illustrated embodiment, as shown in FIGS. 1 and 2, the sticking tape receiving member 66 of the tube sticking means 18 gradually descends the sticking tape 4 toward the downstream side in the transfer direction of the marker tube 2. It is placed so as to be inclined so that the marker tube 2
This is to prevent the adhesive tape 4 from interfering with the transfer of the marker tube 2 when advancing to the adhesive area.

According to the present invention, as described above, the marker tubes are set by cutting the adjacent marked tube portions of the marker tubes in half and completely cutting the adjacent marker tubes. If you attach two or more tube parts that should be connected in half cut state to the adhesive tape, the efficiency of the attaching work will be improved, and the marker tube will be used as a whole set in the process of covering these wires with the wires. Since it is peeled off from the adhesive tape and processed, the subsequent processing of the marker tube is easy, and since two or more tube parts that form a set are continuous at the half cut part, these can be done before attaching the marker tube. There is no risk of losing the tube part.

In particular, when two or more tube portions to be the respective marker tubes are cut in half, and the portion to be each of the marker tubes and the subsequent tube portion are completely cut, the marker tubes are the same. It is formed from three or more tube sections with marker markings, so that, for example, if this marker tube is used to identify a wire, two tube sections will be attached to both ends of the wire and the other tube section will hold the wire. When connecting to another device or the like, it can be used as a confirmation marker for checking whether the correspondence is correct or not, and can be used as a discarding marker after the connecting work.

Further, the feeding and pasting operation of the sticking tape are prevented from being performed without disconnecting the tube cutting means in the half-cutting mode of the tube cutting means, and to the tube cutting means in the full-cutting mode of the tube cutting means. With the interlocking operation, the tape attaching means can be driven by utilizing the operation of the tube cutting means, and thus the tube attaching means can be easily formed with a simple structure.

Particularly, the switching of the tube cutting means between half-cut and full-cut and the feeding and sticking operation of the sticking tape are performed as follows.
When the tube is cut in half, the feeding and pasting operation of the sticking tape is not performed, but when cutting the tube in full, the feeding tape and the sticking operation of the sticking tape are performed together. It is easy to switch the set as a set, and the control of the entire apparatus becomes simple.
