Description

  The present invention relates to a cutting machine, and more particularly to a handy controller thereof.

  When cutting a material to be cut such as woven fabric, knitted fabric or leather with a cutting machine, it is necessary to align the cutting pattern with respect to the material to be cut or to match the pattern of the material to be cut. In this regard, Patent Document 1 (Japanese Patent Laid-Open No. 7-324213) projects a cutting pattern from a projector onto a material to be cut, and an operator moves the projection pattern from the projector by a handy controller to align the material with the material to be cut. Etc. are disclosed. Cutting is taught by adjusting the position of the projection pattern, and the cutting head cuts the material to be cut along the projected pattern that has been aligned.

  Here, in order to operate the projector or the like, it is necessary to input a moving direction such as up (奧), down (front), right, left, etc. from the handy controller. Since the cutting machine has a fixed controller on one side, it is easy to make the movement direction based on the fixed controller side of the cutting machine. However, if this is done, when the projector or the like is operated from the opposite side of the fixed controller, the relationship between the top, bottom, left, and right is reversed, and the operator's sense does not match.

JP-A-7-324213

  An object of the present invention is to make the relationship between the front side and the heel and the right side and the left side coincide with the operator's senses even when the handy controller is operated from either side of the cutting machine.

A setting means for switching the setting of the direction instruction input unit according to the detected position or direction is provided.

  If the position of the handy controller with respect to the cutting machine can be detected, it is possible to know how to change the setting of the direction instruction input unit. Further, when the operator operates the handy controller, the direction should be determined according to the position. Therefore, if the orientation of the handy controller can be detected, it is possible to know how to change the setting of the direction instruction input unit. For this reason, in this invention, even if the handy controller is operated from either side of the cutter body, the setting of the direction instruction input unit can be switched so as to match the operator's feeling. Therefore, the operation of the cutting machine is facilitated.

  Preferably, the detection means comprises a combination of a transmitter provided on one of the cutter body and the handy controller and a receiver provided on the other. In this way, the position of the handy controller with respect to the cutter body can be easily detected.

  Preferably, the detection means is a gyroscope provided in a handy controller. The orientation of the handy controller can be detected by the gyroscope. And when the operator operates the handy controller, the front of the handy controller should be facing the cutting machine, so if the orientation is known, the position of the handy controller relative to the cutting machine can be known, and the setting of the direction indication input unit can be set It can be switched according to the position.

  By providing a projector that projects the image of the part shape on the material to be cut on the cutting bed and moving the image of the part shape according to the direction instruction input from the handy controller, the part can be easily moved against the material to be cut.

  In the following, an optimum embodiment for carrying out the invention will be shown. The scope of the present invention should be construed in consideration of the possibility of modification by well-known techniques in the description of the scope of claims.

  1 to 6 show an embodiment and its modifications. In the figure, reference numeral 2 denotes a cutting machine, which includes a cutting machine body composed of a cutting bed 3 and a cutting head 14. Reference numerals 4 and 6 denote conveyors, for example, the conveyor 4 is a conveyor that feeds the material to be cut and feeds it onto the cutting bed 3, and the conveyor 6 is a conveyor that carries out the material to be cut. The cutting machine main body includes a fixed controller 8 and 10 is a handy controller which is carried by an operator. A projector 12 projects a projection pattern 26 representing the shape of a part to be cut onto the material to be cut on the cutting bed 3. The cutting head 14 moves in two directions XY in the horizontal plane along the arm 22 and the guide rail 24, and includes a cutting blade 16, a laser pointer 18 for instructing the cutting start point and the inclination of the material to be cut, and the like. A camera 20 for taking an image of the material to be cut is provided. In addition, you may provide the camera 20 in the position of the projector 12, for example separately from the cutting head 14. FIG. A1 to A4 are antennas that transmit radio signals having different frequencies, for example.

  FIG. 2 shows the configuration of the handy controller 10 and the like. 30 and 31 are input units. Among these, the input unit 30 is used for direction input, and includes, for example, four direction instruction buttons 41 to 44 for inputting a moving direction and a ring 45 for inputting a rotation direction. ing. The input unit 31 receives an input other than a direction instruction from an appropriate button or the like. Note that the input unit 30 may input the movement direction and the rotation direction by tilting or rotating a knob or a stick instead of the buttons 41 to 44 and the like. In addition, a touch panel or the like may be provided, and an instruction of the moving direction may be received depending on which direction of the four corners of the touch panel is touched.

  A transmission control unit 40 controls transmission to the fixed controller 8. A transmission / reception unit 32 separates signals received from the antennas A1 to A4 by the bandpass filters B1 to B4 and performs AD conversion by the AD converter 34. The comparison unit 36 compares the relative strengths of these four signals, and detects the position of the handy controller with respect to the cutting machine body.

  Here, the side where the fixed controller 8 is located is the front, and the opposite side is the back. If the handy controller 10 is on the front side, the signals from the antennas A1 and A2 are strong, and the signals from the antennas A4 and A3 are weak. Therefore, the comparator 36 compares the strengths of the signals A1 and A4, and similarly compares the strengths of the signals A2 and A3. If the signals A1 and A2 are stronger than the signals A4 and A3, the handy controller 10 is on the front side. In the opposite case, it is on the back side. In the absence of the conveyors 4 and 6, the operator can enter the left and right sides of the cutting machine 2. When this position is also detected, the signal from the antenna A1 is compared with the signal from the antenna A2, and similarly, the signal from the antenna A4 and the signal from the antenna A3 are compared.

  The comparison unit 36 can determine whether the handy controller 10 is on the front side or the back side of the cutting machine 2. In response to this, the direction setting unit 38 switches the setting to the input from the direction instruction buttons 41 to 44. The setting for the input from the ring 45 is constant regardless of the position of the handy controller 10. That is, regardless of the position of the handy controller 10, if the ring 45 is rotated clockwise, the rotation is clockwise.

  Settings for input from the input unit 30 are shown in FIG. The setting 50 on the left is a setting when the handy controller 10 is on the front side of the cutting machine, and the upper and lower sides (in front of the cutting machine 2 and the front side) and the left and right coincide with normal meanings. The setting 51 on the right side is a setting when the handy controller 10 is on the back side of the cutting machine 2, and the upper, lower, left, and right are reversed from the normal meaning.

  If the handy controller 10 is at the position of the conveyor 4, the button 44 of the input unit 30 is a button for moving left, the lower button 42 is a button for moving right, and the button 41 is a button for moving up. , Button 43 is a button for moving down. When the handy controller 10 is at the position of the conveyor 6, the button 44 is a button for moving right, the button 42 is a button for moving left, the button 41 is a button for moving down, and the button 43 is a button for moving up To do.

  As described above, the setting for the input to the input unit 30 is switched depending on the position of the handy controller 10, thereby matching the meanings of the upper, lower, left, and right viewed from the operator and the upper, lower, left and right in the input unit 30. And according to an operator's direction instruction | indication, a signal is transmitted to the antenna A1 connected with the fixed controller 8 from the transmission control part 40 via the transmission / reception part 32. FIG.

  In the fixed controller 8, the projection pattern 26 is changed by moving the projector 12 or changing the position and inclination of the image generated in the projector 12 in accordance with the input from the handy controller 10. Further, the cutting head 14 is moved by the head moving unit 15 in accordance with the input from the handy controller 10.

  In the embodiment, the signals are transmitted from the antennas A1 to A4 and received by the handy controller 10. On the contrary, the handy controller 10 may transmit radio waves and the like and receive the antennas A1 to A4, and compare the reception strengths of the respective antennas. The signal is not limited to wireless, but may be infrared light, ultrasonic waves, or the like.

  FIG. 4 shows a modified handy controller. In this modification, the direction of the handy controller 10 is obtained by the signal of the gyroscope 52, not by the strength of the signals from the antennas A1 to A4. Then, assuming that the operator holds the handy controller 10 toward the cutting machine 2, the direction setting unit 38 switches the setting to the input from the input unit 30 according to the signal from the gyroscope 52. Other points are the same as in the embodiment. Note that the orientation may be obtained by using, for example, a geomagnetic sensor instead of the gyroscope.

  FIG. 5 shows an alignment or pattern matching algorithm using the projector 12. In step 1, an image of a part shape is projected on the material to be cut. At this time, the projected image is at the standard position. In step 2, the direction instruction input from the operator is received, the direction instruction input is interpreted according to the position or orientation of the handy controller (step 3), and the projection image is moved accordingly (step 4). When the position and inclination of the projected image are good and the part-shaped image has succeeded in pattern alignment or alignment with the material to be cut (step 5), the amount of movement of the projection image from the standard position is stored (step 6). ). In addition to the vertical and horizontal movement amounts, the movement amount includes a rotation amount corresponding to the inclination of the sheet material. Then, the operation of the cutting head is changed by the amount of movement with respect to the standard, and cutting is executed.

  FIG. 6 shows a teaching algorithm for the cutting head. For example, the laser pointer of the cutting head is turned on in step 11, and the operator's direction instruction input is accepted in step 12, and the direction instruction input is interpreted in the same manner as in FIG. Then, the cutting head is moved in accordance with the direction instruction input (step 14), and the cutting start point and the tilt direction of the material to be cut with respect to the cutting bed are input. For example, if two positions are input along the longitudinal direction of the material to be cut, the inclination is input. When the input of the cutting start point and the inclination of the material to be cut is completed (step 15), the cutting start point and the inclination are stored (step 16).

  In this way, it is possible to perform pattern matching or position alignment of parts to the material to be cut or teaching with the algorithms shown in FIGS. Pattern alignment is to align the position of the part with the pattern of the material to be cut, and alignment is to determine the position of the part according to the position, inclination, wrinkles, etc. of the material to be cut. Pattern alignment and alignment are similar and both are positioning.

In addition to instructions for moving the projector and cutting head, for example, when shooting the material to be cut while moving the camera sequentially, it is easy to move the camera according to the operator's intention using the direction instruction input to the handy controller. Can be made. In the embodiment, the fixed controller is integrated with the cutting machine main body, but the fixed controller may be separate from the cutting machine main body. In the embodiment, the direction setting unit is provided only in the handy controller. However, the direction setting unit may be provided in both the handy controller and the fixed controller, or only in the fixed controller.
