Description

 Wire Marking Device {APPARATUS FOR WIRE MARKING}

The present invention relates to a wire marking apparatus.

The present invention relates to a wire marking method and an apparatus using the method. 1 is a diagram showing the configuration of a conventional wire marker. The blue box represents the cutter, which is installed after the head for marking.

However, this marking system causes the loss of the wire used, which can cause cable damage as much as the operator operating the marking machine cuts at the beginning of the wire and a certain distance loss due to the autofeeding function of the cutter. The loss of the cable may occur because the distance between the cutter and the header of the marker cannot be marked.

In addition, when the wire marking is finished, the wire is cut after printing a fixed quantity. As much as the cable between the cutter and the marking machine does not need to be marked before cutting, the marking is lost because the marking is lost. Even when changing data, losses occur as much as already marked cables between the cutter and the marking machine.

Conventionally, after measuring the distance between the cutting machine and the header in advance using a signal of the cutter, using an encoder to calculate the traveling speed of the wire. More specifically, when the cutter of the cutter cuts in FIG. 1, the signal is transmitted to the marking machine and used as a print signal (PrintGo) to mark the wire. This has the advantage of not adding a separate signal, but the cutting signal in the cutter Until this occurs, the amount of wire fed to the cutter will be lost, and if there is a variety change, the marking information should be set on the cutting machine.

In addition, there is a method for marking the cutting signal cutting wire using a PLC and a sensor, which can be controlled in detail, but has a disadvantage in that a separate system must be constructed.

In addition, delay can occur when fine control is not performed, resulting in increased wire loss. Fig. 2 shows such a situation that the cutting occurs and the print head prints, but when the cutting signal is delayed, all of the lost parts are located in front of the actual printing part. In FIG. 2, the portion marked with the cutting edge, the portion between the printhead, and the portion marked with yellow are all lost of the product, and only the portion marked with gray becomes a marked portion.

Republic of Korea Patent Publication No. 2000-0047135 'cable marking device' is to enter the character to mark on the sheath of the cable and input a certain length to automatically mark the corresponding character on the sheath of the cable for a certain length Besides, there is no description of the cutting device, so there is no prediction about the problems occurring during cutting.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for reducing losses that may occur in cable marking and cutting. ㅇ

In order to achieve the above object, the present invention provides a wire marking apparatus comprising: a print control unit capable of editing the print content and receiving and storing the print content; a print head unit for actually printing the printed content; from the print control unit A PLC unit for receiving the print contents and instructing an operation of the print head unit; a first encoder unit for checking a traveling length of a wire to be printed; and a cutting signal generation unit for receiving a cutting signal received from a cutting machine; The marking of the wire is started by the start signal input from the print control unit. When the cutting signal is received by the cutting signal generator, the PLC unit compares the distance between the print head and the cutter and the distance of the actual marking by the first encoder. It may be to adjust.

 The PLC unit may have as many buffers as the number of marking positions to adjust the marking positions.

 One or more heads of the print head may be located, and the position of the head may be represented by a relative distance away from the length D between the print head and the cutter.

The printing control unit may be input to the number of production in advance so that only the marking of the number of production is made so that the loss of the breeding change and the end point may not occur.

The invention as described above has the effect of reducing the loss of wire caused by wire marking and cutting.

1 and 2 show a conventional marking apparatus.
3 to 10 show an embodiment of the marking apparatus according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings. Figure 3 is a diagram showing the configuration of a system according to the present invention and Figure 4 is one embodiment according to the present invention.

Conventionally, the actual marking is started from the cutting machine when cutting, but the device according to the present invention calculates the distance between the cutting machine and the marking head in advance, and then starts the marking. You will find. . That is, the first print signal (PrintGO) signal is to mark the wire by the PLC and the encoder, and when a cutting signal is generated, the print signal (PrintGO) is generated based on the cutting signal.

In FIG. 3, the print controller 31 may set the content to be printed at the time of wire marking. To this end, the print section control unit 32 controls the marking position, and the print content editing unit 33 allows the user to receive the print content. In the case of multiple heads, it is decided which color is marked at which position, and the marking contents are stored in advance in the data storage 35. Also, the head control unit 34 controls the print head so that it can actually be printed.

Reputation for controlling the print head in the head control unit 34 is transmitted to the print head unit 37 through the PLC (control unit, 36) and the PLC 36 is the print control unit 31, including the print head (37) In response to the signals from the first encoder 38 and the cutter 41, the entire system is controlled.

The first encoder unit 38 calculates the length of the wire entering through the print head, and calculates the progress of the wire entering the printer head through the first encoder unit through the rotation amount (or the number of pulses) of the encoder and the outer circumferential length of the encoder. do.

The cutter 41 includes a second encoder portion 42 for calculating the length of the wire coming into the cutter, the cutter roller 44 for introducing the wire into the cutter 43 of the cutter, and the cutter 43 for actually cutting the wire. And a cutting signal generator 44 which generates a cutting signal when the cutter is cutting.

Conventionally, when a cutting signal is generated, the marking is started, and a portion that is not marked by a delay after the incoming wire or the cutting signal occurs until the cutting signal is generated. Loss could occur. However, in the present invention, the first PrintGO signal is generated by a push button by automatic or manual operation, and after the PrintGO signal, the length of the wire drawn into the cutting machine from the first encoder is calculated, and the movement until the first cutting occurs is The operator can be moved finely by the moving button of the cutting machine.

Fig. 5 illustrates this situation, in which Fig. 5 is a situation where a wire is drawn through the printhead from the left to the right toward the cutter. The wire is moved toward the cutter by the operator's push button click, and fine movement occurs by the operator's movement button until the cutting occurs, and the movement length is detected by the first encoder. When the first cutting occurs, the cutting machine sends a cutting signal to the PLC unit through the cutting signal generating unit 44, and subsequent PrintGO signals are generated based on the cutting signal generation.

The distance between the printhead and the cutter is already set to the calculated distance (D) (1000mm in Fig. 5). The marking point is calculated based on this distance, as shown in Fig. 6. It can be further behind or further ahead. Since the length between the printhead and the cutter may have changed for some reason, it will recalculate the marking point changed by the delay or the like based on the current cutting signal receiving point. An example of this is shown at the lower end of FIG. The first marking point was 50mm and 250mm of the 300mm wire, but after receiving the cutting information, it changes with the change information.

In order to generate such change information, one change buffer is used for each marking position, and the number of marking positions and the number of change buffers are equally used.

In this way, the loss caused by the operator at the beginning of the cable can be reduced initially, and the loss that can occur at the end of the cable can be solved by the operator entering the cable production number, marking the production number, and not marking it afterwards. The loss of the change point can be solved by the operator inputting the number of cable production through the print control unit, marking the number of production and then marking the next marking information. 7 illustrates this situation.

8 shows an example with three printheads for various information. Each print head has head control part to control each head. Head 1 (Red R) has D value from the origin. Head 2 (Green G) is D + 100, 3 head (Blue) B) is mechanically set to D + 200 and head # 4 (yellow Y) to D + 300. As a result, the printhead does not move and the marking order of the color ring can be changed.For example, print YYYY. In this case, the parameters are D, D + 100, D + 200, and D + 300.

Table 1 below shows an example of printing by controlling the print head.
