The screw shaft 14 is rotated in any direction by the handle 14a, thereby moving the slide member 6 back and forth, and the front part whose movement is restrained by the guide column 7 etc. Part surface plate 3
The cutting thickness is set by slightly moving the front surface plate 3 only in the vertical direction, and when the front surface plate 3 is to be moved vertically, the pistons 9, 9 are slightly extended upward to lock the locking jaws 10, 10 in the locking plate. 12 from above as shown in Figure 1.

In this embodiment, in the known vertical slicer exemplified above, a drive chain 22 is attached to the main shaft of a reversible motor 21 installed on an installation frame 1, as shown in FIGS. gear 23
A known rotary transducer 25 is connected to the tip of the screw shaft 14 so that the rotation of the screw shaft 14 can be controlled by a motor. A bracket 24 provided and fixed on the installation frame 1
A slit disk (known) provided with a large number of transparent slits of the transducer 25 is rotated by the screw shaft 14, and the screw shaft 1
Converts the rotation speed of 4 into electrical pulses. The conversion ratio depends on the number of transparent slits formed in the slit disk, and for example, the number of output pulses is 100 to 500 per revolution of the spring screw shaft 14. In addition, by one rotation of the screw shaft 14, the slide member 6, for example,
mm so that the front upper plate 3 can be moved vertically by 0.625 mm. The numerical values exemplified above can be changed freely.

Reference numeral 27 indicates an operation panel, and a set counter 28 for setting the setting value of cutting thickness by rotating several number wheels 28' and a set counter 28 for setting correction values by rotating several number wheels 28'.
A set counter 29 for correction that sets a number by rotating the counter 9', a push lead switch 30 attached to the set counter 28 for setting, a push lead switch 31 attached to the set counter 29 for correction, and a digital numeric display. It includes a plate 32 and the like. The correction set counter 29 is provided with a rotary wheel 29'' for displaying , coaxially with the number wheel 29'.

The present invention is a set counter 2 of both types mentioned above.
The microcomputer 26 is controlled using the push-button switches 8, 29 and push-button switches 30, 31 as operation heads, and the operation mode thereof is as follows.

Set the number ``200'', which indicates the cutting thickness, for example, 2 mm, by rotating the number ring 29' of the setting counter 28, and then turn the push lead switch 30.
When is pressed, the above-mentioned numerical value is input into the microcomputer 26, which stores the value converted into the number of electric pulses generated by one revolution of the slit disk of the transducer 25, and at the same time, the control box 33 converts the number of electric pulses into reversible pulses. The motor 21 is commanded to rotate in the forward direction and the lock cylinder 8 is unlocked, and the reversible motor 21 rotates the screw shaft 14 to cause the slide member 6 to slide on the installation frame 1. The transducer 25 changes the rotational speed of the screw shaft 14 into a pulse number and inputs it to the microcomputer 26, and when it matches the number of stored pulses corresponding to the set number input from the setting counter 28, the control box 33 At the same time, the rotation of the reversible motor 21 is stopped, and at the same time, the rear surface plate 2 is locked so that it cannot float using the locking cylinder 8, and the level difference between the cutting blade 4, the cutting edge 5, and the contact surface of the front surface plate 3 is set to 2 mm. , thereby setting the cutting thickness of the workpiece.
Further, when the push-button switch 30 is pressed, a signal is sent from the microcomputer 26 to the digital numeric display board 32 to display the digit ``200''.

For example, when the cutting thickness was set at 1 mm last time, calculations are performed in the microcomputer 26 as the pusher switch 30 is pressed, and the reversible motor 21 lowers the front surface plate 3 by 1 mm. Perform 14 rotations.

As described above, set the cutting thickness on the vertical slicer, and measure the thickness of the veneer cut from the processed material using a scale during actual work. For example, if the measured thickness is 1.9 mm (+0.1 mm ), turn the number wheel 29' and rotary wheel 29'' of the correction set counter 29 to set the number "+010" to display +0.1 mm, then press the push-in switch 31. , as in the case of setting the cutting thickness, the above-mentioned correction number is set by the microcomputer 26.
The number is input into the number of electric pulses generated by one revolution of the slit disk of the transducer 25, and is stored,
Correct the cutting thickness by lowering the value by the amount appropriate to the correction value. Simultaneously with pressing the push-in switch 31, a calculation signal from the microcomputer is input, and the digits of the setting counter 28 and the correction set counter 29 are displayed on the digital numeric display board.
It is displayed as "210" which is the sum of the digits.

When the current cutting thickness setting is smaller than the previous one, or when correction is to be performed, the control box 33 rotates the reversible motor 21 in the reverse direction, and the locking cylinder 8 and transducer 25 The effect of sending out electric pulses, etc. is the same.

The present invention has the above-mentioned configuration and function, and the erroneous dimensions found by the thickness inspection using the scale of the veneer separated during actual work are entered by a correction set counter, and the pushbutton attached to the counter is set. It has the effect of automatically correcting errors in the cutting thickness set on the vertical slicer by simply pressing the lead switch.
