Abstract

PROBLEM TO BE SOLVED: To flatten the marking surface of a long material to clarify marking when the long material for marking is soft and uneven or curved, and to prevent imparting deformation such as bending and the like to the long material without applying a flattening function when the long material is hard and flat at its making surface. SOLUTION: When a long material 1 formed out of a long tube is soft, flexible and uneven at its marking surface, the long tube is made flat by passing it through a thermal head 32A while being held between a press roller 46 and a platen roller 30. Meanwhile, when the long material 1 is a hard long tape 1B' having a flat marking surface, a handle 64 is rocked clockwise around a center axis 50 against a spring 48 to separate the press roller 46 from the platen roller 30. Therefore, the hard tape 1B' is prevented from being imparted with bending with no flattening function applied, causing no interruption by bending of the running of the material so that the subsequent processing can be surely carried out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible soft non-flat long material such as a long tube formed of a soft plastic material such as polyvinyl chloride, and a flat hard hard long material. Related to a long material marking device that presses a marking head against a material to mark various characters and symbols, for example, an identification tube and the like that displays various characters and symbols to identify wires and the like and covers the wires. A long material marking device used to mark letters, symbols, etc. on soft tubing materials for manufacturing, or to mark letters, symbols, etc. on hard tape materials for manufacturing various marking labels It is related to the improvement of.

[0002]

2. Description of the Related Art Recently, a marking head has been pressed against a long material via a marking tape, and characters,
2. Description of the Related Art A long material marking apparatus including a marking means for marking a symbol and the like and a long material flattening means for flattening a printing surface of a long material to be fed to the marking means is used.

[0003] In this apparatus, for example, when the long material is a non-flat flexible soft material having a circular or elliptical cross section such as a tube, the marking surface can be flattened to perform clear marking. This is advantageous because it can be performed.

[0004] Even if there is no long material flattening means,
The tube can be flattened by the pressure of the marking head while the material is softened by the heat of the marking head.However, for this purpose, the pressure and current of the marking head must be increased, and the hardness of the tube depends on the season. If the height is increased, the marking head may be lifted by the repulsive force of the tube without completely flattening the tube, and the marking may be blurred. However, it is advantageous to have a long material flattening means, because such a disadvantage can be avoided.

On the other hand, a long material marking apparatus is a device in which a long material to be marked is a long material other than a tube,
For example, when the marking surface is a hard long material whose marking surface is originally flat, such as a hard tape, when the flat hard long material is passed through the flattening means, a deformation such as bending is given to the long material. Is done.

[0006] The long material provided with such a bend is
When the subsequent processing such as cutting is performed after passing through the marking means, the long material is not fed straight due to its deformation, so that the post-processing cannot be continuously and smoothly performed.

For example, when a long material such as a hard tape is passed through a long material flattening means, the hard material is bent upward in the running direction by the long material flattening means. After the marking is made on the marking surface of the hard tape, for example, when the hard tape is fed to the cutting means and cuts the hard tape for each marking section, the leading edge of the hard tape is bent upward of the hard tape. As a result, it is impossible to proceed so as to slip under the cutter of the cutting means, and the cutting operation is hindered.

[0008]

The problem to be solved by the present invention is that when a long material is soft and its marking surface is a non-flat surface such as a curved surface, the marking surface is flattened, When the long material is hard and its marking surface is flat, the long material can be marked without giving a deformation such as bending to the long material.

The lock mechanism 66 is shown in FIGS.
As shown in FIG. 6 to FIG. 6, particularly FIGS. 64, as shown in FIG.
And holds the press roller 46 at a position away from the platen roller 30.

Next, the long material marking apparatus 1 of the present invention
0, the elongate material flattening means 16 presses the press roller 46 against the platen roller 30 by a spring 48 to press the elongate material 1A immediately before the thermal head 32A, as shown in FIG. The platen roller 30 and the press roller 46 are maintained in a state having a flattening function.

In this state, when the long material 1 is a soft flexible long tube 1A 'having a non-flat marking surface, the long tube 1A' is, as shown in FIG. The paper passes between the press roller 46 of the long material flattening means 16 and the platen roller 30 of the marking means 14 and passes through the marking means 14, the long material feeding means 12 and the material cutting means 18. Therefore, this long tube 1A '
Is flattened by being sandwiched between the press roller 46 of the long material flattening means 12 and the platen roller 30, and the flattened long tube 1A 'is marked with the marking tape while maintaining the flattened state. Thermal head 32 with 2
A passes between A and the platen roller 30.

In this manner, the thermal head 32A of the marking means 14 applies a series of markings to the marked portion (marking surface) of the long tube 1A 'via the marking tape 2. During the marking, the long material feeding means 12 pulls the long tube 1A 'in synchronization with the marking tape 2 so as to feed it while contacting the thermal head 32A.

When a series of markings are made and the thermal head 32A rises, the feeding of the marking tape 2 stops. The long material feeding means 12 includes a long tube 1A '
With the first series of marked tube sections to transfer subsequent tube sections to be marked to the marking area. As can be seen from FIG. 1, in this case,
The portion to be cut between the first marked tube portion and its subsequent portion is located in the cutting area (the area having the cutter 36) on the cutting table 34 of the material cutting means 18.

Next, the thermal head 32A is lowered again, and the next series of markings is applied to the tube portion in the marking area, thereby forming a subsequent marked tube portion. While the second marking is being performed, the cutter 36 of the material cutting means 18 descends and cuts between the front and rear tube portions to form the marker 3 consisting of the first marked portion.

On the other hand, along with the cutting operation of the tube, the marker attaching member 40 of the material attaching means 20 descends, and the marker 3 is attached on the attaching tape 4. After the application of the marker 3 is completed, the application tape 4 advances by a predetermined pitch to prepare for the application of the next marker 3.

The subsequent tube portion is sequentially marked, and the marked portion is cut to form a marker 3. These markers 3 are similarly pasted to the pasting tape 4 in the same manner.

Next, when the long material 1 is a hard long tape 1B 'having a flat marking surface, the handle 64 of the eccentricity canceling means 58 is pivoted around the central axis 50 as shown in FIG.
Is angularly displaced from the position shown in FIG. 4 to the position shown in FIG. In this way, the eccentric support member 52 of the elongated material eccentricizing means 16 swings about the central axis 50, and thus the eccentric shaft 54 supported by the eccentric support member 52 extends the spring 48 to the central axis. The press roller 46 swings so as to be eccentric about the center 50 and separates from the platen roller 30.

At this time, as shown in FIG. 6, the handle 64 is locked to the notch locking portion 72 of the lock mechanism 66, so that the spring 48 is maintained in the extended state, and the press roller 46 is , And is locked away from the platen roller 30.

The long tape 1B 'is, as shown in FIG.
Elongating material flattening means 16 Marking means 14, elongate material feeding means 12 passing under open press roller 46
And material cutting means 18. Therefore, the long tape 1B ′ directly passes between the thermal head 32A and the platen roller 30 together with the marking tape 2 without receiving the flattening function.

Subsequent processing of the long tape 1B ', like the long tube 1A', is cut through the material cutting means 18 and the material sticking means 20 for each marking section, and is then stuck to the sticking tape 4. . It should be noted that the long material flattening means 16 has been released from the flattening function by the flattening release means 58, so that the long tape 1
B 'is not bent. Therefore, for example, since the leading end of the long tape 1B 'runs reliably so as to be located below the cutter of the material cutting means 18, cutting of the marked long tape 1B' and other processing are hindered. Therefore, the post-marking process can be performed smoothly.

When the handle 64 is in the non-release position in FIGS. 1 and 2 or in the release position in FIGS. 4 and 5,
Since the spring 70 functions to press the handle 64 via the eccentric support member 52 to the portion of the handle engagement wall 22A that does not have the notch engaging portion 72 and the portion that has the notch engaging portion 72, the handle 70 The flattening position of the press roller 46 and the release position thereof can be reliably maintained without deviating from the respective positions of the press rollers 64.

In the above embodiment, the pressing member 46 is
Although it has a roller shape, any other shape other than the roller shape can be used as long as the non-flat marking surface of the long member can be flattened.

In the above-described embodiment, the platen roller 30 of the marking unit 14 is used as the receiving member facing the press roller 46 as the material flattening unit, but a receiving member separate from the platen roller 30 is used. Is also good.

Further, the eccentric support member 52 of the flattening releasing means 58 is in the form of a crank arm in the illustrated example, but may be of any form such as a cam for lifting the press roller 46 from below. Eccentric support member. In this case, the release member 60 is a rotation handle of a cam shaft that supports the cam, and the lock mechanism 66 can be in any form such as a snap that holds the cam shaft at a predetermined rotation angle position. Of course, even when the release member is in the form of the swinging handle shown in the figure, the lock mechanism can be in any form other than the notch engaging portion.

In the above embodiment, a long tube is taken as an example of a soft flexible long material having a non-flat marking surface. However, a long member having a semicircular cross section, a long member having a hollow kamaboko type, or the like is used. A long tape is used as an example of a hard long material having a flat marking surface, which can be applied to a long member of any form. Can be similarly applied to those in which the sheets are attached at intervals and other arbitrary forms.

In the above embodiment, the marking head 3
2 is the thermal head 32A, which can be in the form of a heated and pressurized type ring assembly or any other form.

[0054]

According to the present invention, as described above, when the long material is soft and the marking surface is a non-flat surface such as a curved surface, the long material flattening means is used for the long material. When the marking surface is flattened, and the long material is hard and the marking surface is flat, the function of the long material flattening means is released by the flattening releasing means and bent into a long material. The marking can be applied to the long material without giving the deformation of the long material.

Therefore, a single common marking device can perform marking on both a soft long material having a non-flat marking surface and a hard long material having a flat marking surface.

Further, the state in which the long material flattening means functions and the state in which this function is released can be easily switched by operating the eccentric support member with the handle, so that the handling is easy and the structure is simple. Therefore, the size of the apparatus is not increased.

A hard long material having a flat marking surface is not subjected to bending by the long material flattening means, so that it does not hinder the post-marking process and can perform post-marking processing. Can be performed smoothly.
