  • Fig. 1 is a view showing the schematic structure of the stamping apparatus 10 in an embodiment of the present invention.
  • the stamping apparatus 10 is approximately structured by a reciprocating mechanism section 1, pressure control circuit 2, two-dimensional positioning mechanism section 3, positioning control circuit 4 and stamping oscillation generating circuit 5. Further, the reciprocating mechanism section 1 is structured by a motor 1a, cam 1b, cam follower 1c, dog 1d, holding portion 1e, pen 1f, stylus 1g, up-movement end detector 1h, down-movement end detector 1i, shaft 1j, coil spring 1k, fixed plate 1l, stopper lm, bearing 1n, and the like.
  • the motor 1a is attached on the fixed plate 1l, and when the motor 1a is driven and the cam 1b is rotated, the holding portion 1e is linearly moved through the cam follower 1c.
  • the holding portion 1e is fixed on two shafts 1j, and is always pressed onto the cam 1b side by the coil spring 1k. Therefore, as the cam is rotated, even when the holding portion le is pressed and lowered toward the material to be stamped 6 side, or even when the holding portion le is separated from the material to be stamped 6 side, the holding portion 1e is moved following the cam 1b.
  • the cam 1b has the shape in which the stylus 1g attached on the tip portion of the pen 1f can be pushed onto the material to be stamped 6 by a predetermined pressure by the predetermined torque from the motor 1a, without depending on its rotation position.
  • the stylus lg is made of the material having the higher hardness than the material to be stamped 6, and by being oscillated in the up and down directions at high speed, point stamping is repeated onto the material to be stamped 6.
  • a bearing 1n is housed in the fixed plate 1l, and the shaft 1j is guided by the bearing 1n, and linearly moved. Further, the cam follower 1c and the pen 1f are attached onto the holding portion 1e, and the up movement end detector 1h detects the dog 1d when the tip of the pen 1f attached on the bottom surface of the holding portion 1e is at the position of the up-movement end, and the down movement end detector 1i detects the dog 1d at the position of the down-movement end.
  • the pressure control circuit 2 controls the speed of the reciprocating movement of the pen 1f by controlling the rotation speed of the motor 1a, as will be described later. Further, the pressure control circuit 2 detects the arrival to the material to be stamped 6 when the pen 1f comes into contact with the material to be stamped 6 during the reciprocating movement of the pen 1f, and after the contact of the pen 1f with the material to be stamped 6, the pressure control circuit 2 controls the pressure of the stylus 1g applied onto the material to be stamped 6 so that it becomes a predetermined value.
  • the pressure control circuit 2 reversely rotates the motor 1a, and when the stylus 1g reaches the up-movement end, the pressure control circuit 2 stops the motor 1a, and outputs the alarm.
  • the two-dimensional positioning mechanism section 3 positions the two-dimensional pattern such as characters or numerals in the perpendicular direction to the stamping axis, according to the positioning control signal outputted from the positioning control circuit 4.
  • the reciprocating mechanism section 1 causes the pen 1f to contact with pressure with the material to be stamped 6 under the condition that the pen 1f is oscillated, and stamps the characters and numerals on the material to be stamped 6.
  • the stamping oscillation generating circuit 5 causes the pen 1f to generate the oscillation.
  • a fulcrum 101 expresses the fulcrum of the cam 1b which is a rotation shaft of the motor 1a
  • the contact point 102 expresses the contact point of the cam 1b with the cam follower 1c.
  • [R] expresses the distance between the fulcrum 101 and the contact point 102
  • [F] is the reaction force from the material to be stamped 6
  • [T] expresses the torque which is generated in the fulcrum 101 by [F].
  • [ ⁇ ] expresses an angle formed between the direction of the reaction force [F] and the direction of the reaction force of the cam follower 1c to the cam 1b
  • [ ⁇ ] is an angle formed between the direction of [F] and the direction of [R]
  • [ ⁇ ] expresses an angle formed between the direction of [F] and the direction of [F/cos ⁇ ] respectively.
  • the cam 1b is formed with the curved shape to satisfy the above expression, and when the distance between the fulcrum 101 and the contact point 102 is appropriately changed as the rotation of the cam 1b, the pressure to be applied onto the material to be stamped 6 when a predetermined torque is applied from the motor la, can be kept constant.
  • the change of the length of the coil spring 1k, [F] is changed, however, because the change of [F] is extremely small as compared to the pressure applied onto the material to be stamped 6, it can be neglected.
  • a switch 25 inputs this signal into a comparator 24b so as to make this signal a comparing signal with the chopping wave outputted from a chopping wave generation circuit 26' in a PWM pulse generation circuit 26.
  • the rotation speed of the motor 1a is controlled so that the output signal of the tachometer 1a' keeps a value which is previously set in the pulse ⁇ duty setting section 21a.
  • the pressure control circuit 2 can control the speed of reciprocating movement of the pen 1f to the arbitrary speed.
  • the current value is proportional to the torque, because the movement is restrained when the stylus 1g comes into contact with the material to be stamped 6, the torque of the motor la temporarily becomes excessive. Accordingly, by inputting the voltage of both ends of the current amount detection resistance 28 into the amplifier 29, the voltage is detected, and compared to the torque setting value of the torque setting section 21c previously stored by the comparator 24a, thereby, the arrival to the material to be stamped 6 is detected. Then, when the arrival to the material to be stamped 6 is not detected, the amplifier 29 stops the motor la and outputs the alarm. According to the above operations, the pressure control circuit 2 can detect the contact of the pen 1f with the material to be stamped 6 during the movement in the reciprocating motion.
  • the subtracter 22b and the adder 23b compare the output value of the amplifier 29, which is a signal proportional to the [T], to the pulse ⁇ duty setting value stored in the pulse ⁇ duty setting section 21b, and the signal in which the difference is added to the pulse ⁇ duty setting value, is generated.
  • the switch 25 inputs this signal into the comparator 24b so as to make this signal the comparing signal to the chopping wave outputted from the chopping wave generation circuit 26' in the PWM pulse generation circuit 26. Accordingly, the torque of the motor la is controlled so that the output signal of the amplifier 29 becomes the value which is previously set to the pulse ⁇ duty setting value of the pulse ⁇ duty setting section 21b. According to the above operations, the pressure control circuit 2 can control the pressure applied onto the material to be stamped 6 by the pen 1f, to the predetermined value.
  • the pressure control circuit 2 controls the switch 25 according to the signal to detect the arrival to the material to be stamped 6, because the difference of the weight of the pen If does not influence on the intensity of the collision with the material to be stamped 6, various kinds of pens can be used. Further, the pressure control circuit 2 can conduct the speed control and applying pressure control of the pen 1f so that the pressing force of the stylus 1g becomes the optimum value, thereby, the stamping apparatus by which the homogeneous stamping is conducted onto the processing surface without depending on the material and the shape of the material to be stamped 6, can be structured inexpensively and easily.
  • the stamping apparatus because the reaction force from the stamping section is used and the pressing force applied onto the material to be stamped is directly detected, and the pressing force can be kept constant, thereby, the stamping apparatus by which the applying pressure can be adjusted, can be realized in easy and small sized structure.
  • the material to be stamped can be stamped by the optimum speed and applying predssure corresponding to the difference of the weight of the stamping means or the contact position with the processing surface.
  • the time or power consumption can be saved.
  • the stamping in addition to the effect of the invention according to the first aspect, by keeping the torque applied onto the driving means constant, the stamping can be conducted with the uniform depth without depending on the contact position of the stamping section with the processing surface.
