Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a coordinate analyzer that aligns an index of a reading head with a point to be read on a drawing and measures the XY coordinate values of the point, and marks the point as indicating completion of reading. The present invention relates to a marking device for marking.

Conventional coordinate analyzers generally use a projector as a reading head, and a crosshair indicator is provided on the projection surface of the projector. In order to project a desired position on the drawing onto the projection surface of the projector and read each point on the drawing, the marking ben of the marking device must be kept on standby outside the field of view of the projector. If the marking ben is placed within the field of view of the projector, the marking ben will be reflected on the projection surface, making it difficult to read the points on the drawing. Therefore, the distance between the tip of the marking ben and the marking position becomes long, and when marking a reading point on a drawing with the marking ben, it is necessary to lengthen the movement straw of the marking ben. When the movement stroke of the marking ben becomes longer, the time required for marking becomes longer, and the inertia of the marking ben increases, causing the pen tip to strongly hit the drawing, resulting in a problem that the life of the pen tip is shortened. The present invention solves the above problem by using two driving means to increase the stroke of the marking ben by two.
The purpose of this is to solve this problem by using a staged system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings. First, the outline of the coordinate analyzer will be explained with reference to FIG.

Reference numeral 2 denotes a battle platform, which is attached to the fuselage 4 so as to be movable in the direction of the x coordinate axis. Reference numeral 6 denotes a frame to which a Y cursor 8 is attached so as to be movable in the direction of the Y coordinate axis.

The layer table 2 is configured to be moved in the x coordinate axis direction by an X pulse motor, and the Y cursor 8 is configured to be moved in the Y coordinate axis direction by a Y pulse motor. The control box inside the fuselage 4 is equipped with the necessary devices to drive and control the KY pulse motor, and the operation panel of the fuselage 4 includes several manual switches for operating the ×Y motor and the A display unit 10 is provided that digitally displays the amount of movement of the battle platform 2 and the Y cursor 8 in the XY coordinate axis directions. 12 is projector 1
4 as the main component, and the head 12
is provided with a projection surface 16 on which a crosshair index is formed.

In the above-described configuration, the printed board original is positioned on the battle board 2, and the head 12 is moved to a point on the original to be read. The head 12 can be moved by driving the XY pulse motor by operating a switch. The center of the crosshair index of the projection diagram 16 is aligned with the point to be read, and the amount of X-Y movement of the battle platform 2 and the Y cursor 8 from the origin at this time is read by the display on the display unit 10, Enter this result into the tape punch. In this way, each point on the original map is read,
Input the coordinate data of the original drawing into the puncher one by one. The structure and operation of the above coordinate analyzer are generally known, and therefore, detailed explanation of the structure will be omitted. Next, the marking device will be explained.

In FIG. 2, reference numeral 20 denotes a holder fixed to the base plate 22 of the head 12, and a pen holder 24 is slidably held thereon by an iron insert.

The pen holder 24 is inclined at an angle of approximately 50 degrees with respect to the surface of the stacking table 2, and a felt ben 26 is attached to the tip of the pen holder 24. 28 is an annular body which is screwed into the upper threaded portion of the ben holder 24, and a circumferential groove 30 is formed on the outer peripheral surface of this annular body.

32 is a rotary solenoid fixed to the substrate 22, and one end of an arm 34 is fixed to the output shaft of the rotary solenoid.
The other end of the arm 34 is slidably fitted into the circumferential groove 3. Reference numeral 36 denotes a solenoid fixed to the base plate 22, and the tip of its operating shaft 38 is in contact with the arm 334 via a roller.

The solenoids 32, 36 are connected to control equipment in the control box. The pen holder 24 is biased in the upward direction by a spring (not shown) provided in the holder 20, and the pen holder 241 is in elastic contact with a stopper (not shown) at the 4th set upward position. When the pen holder 24 is in a standby state at the set raised position, the pen 26 is located outside the field of view of the projector 16, that is, the projection range W. In this embodiment, the distance between the tip of the pen 26 and the marking device P, that is, the stroke of the pen holder 24, is set to 13 legs. Next, the operation of this embodiment will be explained. After reading one point on the original drawing,
To mark the reading completion at the point, turn on the marking operation switch on the panel 40.

As a result, first, an operating signal is applied to the solenoid 36, and the operating shaft 38 moves in the protruding direction of the skin cape. As a result, the arm 34 is pushed in the counterclockwise direction of rotation of the hour hand in FIG. 2, and the ben holder 24 is moved diagonally downward to the left by the 10th side.
The descending speed of the pen holder 24 at this time is set relatively fast. When the pen holder 24 has finished descending 10 steps, the solenoid 36 is turned off, and then a drive signal is applied to the solenoid 32, and the output shaft of the solenoid 32 rotates at a predetermined angle in the counterclockwise direction of rotation of the hour hand on FIG. , the arm 34 pushes the ben holder 24 in a diagonally downward direction to the left by three degrees. By lowering the pen holder 24, the ben 26 hits a point on the original drawing or a position adjacent to the point, and marks the point as read completion. The descending speed of the three ribs of the pen holder 24 is set relatively slowly so as not to damage the pen tip. When the pen holder 24 has descended to the marking position P, the solenoid 32 is turned off, and the pen holder 24 is raised back to the set standby position by the elasticity of the spring. In this way, the read point is marked as reading completion, and then the reading operation for other points is started. After inputting all the coordinate data of the original drawing into the tape punch, the tape punch types out the input tape for the numerically controlled machine tool. This input tape can be checked through the steps shown in FIG. The input tape 42 is input to the tape reader 44, and the tape check button 46 on the panel 40 is turned on. When the check button 46 becomes ○N, the solenoid 36 is turned on, and the ben holder 24 descends by 10 degrees and maintains the descended state. Next, when the start button 48 on the panel 40 is pressed, the output pulse of the tape reader 44 is sent to the control device, and the "XY pulse motor 50 is driven, and the head 12
The battle counterfeit table 2 moves according to the coordinate reading procedure, and each time the crosshair index of the head 12 matches the reading position of the original drawing, an ON signal is output to the solenoid 32, and an ON signal is sent to the solenoid 32 for each reading point of the original drawing. A check mark is marked with a pen. This operation makes it possible to check whether there are any reading errors in the original drawing reading process. When checking the input tape 42, place a ben holder on the projection surface 16.
24 is displayed, so during the check operation,
The solenoid 36 remains ON and the ben holder 24
The marking raising and lowering operation is performed exclusively by turning on the solenoid 32,
This is done by OFF operation. As is clear from the above description, the solenoid 36 and the spring provided in the holder 20 serve as a first drive for driving the marking ben 26 in both directions toward and away from the drawing surface. The means constitutes a solenoid 32 and a holder 2.
The spring provided inside the marking ben 26 moves both toward and away from the drawing board teaching surface.
It constitutes a second driving means for driving the.

As described above, the present invention uses two driving means to make the stroke of the pen holder two-stage, and performs the downward movement of the first stage of the ben holder at high speed, and the downward movement of the second stage without damaging the pen tip. Since the marking operation is carried out at a speed that is low enough to avoid any damage, the marking operation can be carried out quickly and there are advantages such as not damaging the bend tip.
