Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to removing stains from a cutter when cutting marks to be pasted on clothing, etc.

(Problems to be solved by the prior art and the invention) In the past, dirt was removed periodically by visual inspection, but work had to be stopped to remove dirt, which resulted in poor work efficiency, and for quality control reasons, marks were stained. This was a problem because it required visual inspection to ensure that it did not get wet, and there was also concern about safety due to heat.

(Means for solving the problem) As shown in Fig. 3, by using a metal brush to move the bit (trowel tip) of the heat cutter in the direction of the moving cleaning pattern within the operating range of Fig. 2. We basically solved the problem by removing the dirt. Conventionally, stains were removed by visual inspection, which was done by adding up marks cut at a certain distance, and removing stains when a certain distance was reached. If cutting is in progress, complete the mark cutting operation and remove dirt.

In addition, by changing the mark cut distance depending on the type of marked area, the optimum distance can be selected to improve the efficiency of dirt removal work.

As shown in Figure 2, in the moving cleaning pattern, the first time is clockwise (CW), the second time is moving within the operating range and counterclockwise (ccw), and so on, and the fifth time is the same as the first time. Shift it slightly to the right and change the rotation from CW to CCW to prevent the metal plan from sagging, and avoid removing dirt in the same place to avoid getting dirt on the mark.

Even if the power is cut off, the moving cleaning pattern before the power is cut off is memorized, and if you want to remove dirt after turning the power on and working again, the machine will move to the next moving cleaning pattern before the power was cut off and remove dirt. We make sure not to carry out removal work in the same place.

13 is a heat cutter for cutting marks.A detailed explanation of the mechanism of the mark cutting device can be found in 1. Mark cutting device, which was filed as a utility model on February 2, 1990, so please click here. I will omit it here.

The functions of the structure will be explained with reference to FIG.

Key 1 is an input means for inputting the type, size, speed, etc. of the pattern to be cut, giving instructions for the cutting operation, and also inputting the type of mark area.

The LCD 2 displays the operating status of the mark cutter and the details of the instructed operation.

The FDD 3 is a device that reads mark data on a floppy disk (FD), and the X-Y mechanism 4 uses a heat cutter 13 to read mark data. Therefore, it is a mechanism that moves on the X-Y plane, and includes a Y motor 6 that moves in the Y direction, a Y motor driver 7 that drives the Y motor, and an X motor that moves in the X direction.
X motor driver 10 that drives the motor 9 and the X motor
, position sensor 8 detects the initial position in the Y direction, and position sensor II detects the initial position in the X direction.

The heater vertical mechanism 12 moves the heat cutter 13 up and down, and when it is at the top it is used to move, and when it is at the bottom it is a mechanism that cuts marks. I am using driver 15. The position sensor 16 is a sensor that detects the position in the Z direction, and is composed of a heater driver 18 so that the temperature of the heat cutter is detected by a temperature sensor 17 and the temperature is kept constant. The CPU 22 controls the movement of the entire device and also integrates the cutting distance. The ROM 23 is a storage device that programs the operation of the device, and also stores a plurality of moving cleaning patterns.

The RAM 24 temporarily stores the mark data of the FD read by the FDD 3 and transfers it to the CPU 22. Mark cutting work is performed according to signals from the ROM 23.

The non-volatile memory 25 is a non-volatile memory that stores the moving cleaning pattern used in the dirt removal operation and the usage range of the metal brush, and the data content does not disappear even when the power is cut off.

Next, the operation of the main program will be explained using the flowchart shown in FIG. When the power is turned on in step 1, the Z-axis motor performs a positioning operation and lifts the cutter upward. Next, the X-axis motor and Y-axis motor are moved to the initial position sensor to perform positioning. At 2, the system waits for key input and waits for the next operation.

In step 4, input a character string or pattern number using the keys, select a mark pattern, and register it in the editing buffer on the RAM. In step 5, by selecting the type of marked area using the key, the reference length for executing the stain removal operation is set. Instead of selecting the type of mark area, the reference length value (XXX
It may also be input as mm). 6, the dirt removal operation can be forcibly executed by key operation (manual execution). When all the standards are correct in step 3, start the mark cutting operation by pressing the start key. At step 7, all mark data of the selected pattern is read from the floppy disk into the data buffer on the RAM. In step 8, one pattern of mark data consisting of straight line and arc components is all converted into displacement amounts (ΔX, Δy) of straight line components, and registered in the development buffer on the RAM. In step 9, the straight line component data stored in the expansion buffer is taken out sequentially from the beginning, and the length of the straight line is determined from the equation Q=1 using the ΔX and Δy components. In step 10, add up the lengths found in step 9. Find the total length of the cut from the SUM 44-8U+U integrated result.

Compare the reference value set in advance in step 11 with the cut length of the marked area, and if the cut length in step 12 is larger, it is assumed that it is necessary to perform the dirt removal operation. Set recognition flag. If it is smaller than the reference value, a cut of one linear acid is executed at 13.

Step 13: Cut the marked area by the length Ω obtained in step 9. 1
Repeat steps 9 to 14 until 1 mark is completed at 4.

When one mark is completed at step 15, the recognition flag for the dirt removal operation is checked, and if the flag is set, the dirt removal operation is executed at step 16 (automatic execution).

Steps 8 to 17 are repeated until cutting of all marks is completed at step I7.

Next, the dirt removal operation will be explained with reference to FIG. At step 18, the range of the metal brush to be used for the dirt removal operation is determined based on the information stored in the non-volatile memory. 19 is 18
Move the cutter to the position determined by . At step 20, lower the cutter and insert the tip of the cutter into the brush for dirt removal operation (Figure 3). At step 21, a moving cleaning pattern for removing dirt by moving the cutter tip within a metal brush is determined based on information stored in the non-volatile memory. At step 22, the cutter is moved as shown in FIG. 2 (diamond-shaped) according to the moving cleaning pattern determined at step 21, and the dirt is scrubbed off with a brush. 23 to lift the cutter. At 24, move to the original position to cut the next mark. In step 25, the range of the metal brush used this time and the movement cleaning pattern are stored in the non-volatile memory. 26 sets the actual cut length to zero and returns it to the initial state.

(Effects of the Invention) Since the dirt removal operation is automatically executed while cutting a plurality of marks, the work can be continued without staining the cut marks with dirt attached to a part of the cutter.

Since the type of marking area can be specified, the cutting distance when executing dirt removal operations can be set to the optimum value, and the frequency of dirt removal operations can be kept to a minimum, so that dirt removal operations are not performed unnecessarily. This increases work efficiency.

Since the range of use of the metal plano is shifted each time, the dirt removed in the previous dirt removal operation does not adhere to a part of the cutter again. In addition, the metal planer does not use the same location, and the rotating direction of the moving cleaning pattern is rotated CW and then CCW around the same location, so the metal brush is less likely to wear out, extending the life of the metal plan. Since it remembers the location even when the power is turned off, it can restart from the state it was in before the power was turned off, so there is no dirt attached, which is extremely effective.
