The present invention relates to a pen holding device for automatically controlled pen plotter (Pen Plotter).

In the conventional pen holding device, the pen is insecurely fixed by only one fixing arm and one clamp, and the pen can be enlarged by not penetrating the center of the pen table clamp. Since there is no function to push the pen forward by using the rotation of the replacement is not sure, there is a problem that the pen falls.

Therefore, an object of the present invention is to install an L-shaped rotary clamp in the cavity of the fence table clamp so that the pen holder of the pen flutter pen holder device can be compactly formed. The copper pin expands the rotation clamp of the fence table clamp and, in response, pushes the pen held by the rotation radius of the L-shape clamp and simply takes over the pen holder clamp, and the pen holder clamp holding the pen moves to the carriage pen holder replacement position. The present invention provides a new pen holding device that can increase the reliability of the pen exchange operation by pushing the sliding pin on the rotating arm of the carriage pen holder to expand the carriage arm of the carriage pen holder and at the same time accepting the pen.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The arm extends in parallel to the rotary clamp 3 located on the opposite side of the fixed fixed arm 2 by using the cavity speed of the stable pen holder 1 as in the first diagram. The end portion is easily refracted for holding of (P).

FIG. 2 shows a carriage pen holder 4 having a pen exchange function with the above-described stable pen clamp, and a rotary arm 5 coupled between two arms extending substantially parallel to the rotary clamp 3 of the stable pen holder 1. The elliptical sliding pin 6 penetrates up and down and is fixed to the end thereof, and the tip portion thereof has a hook shape to act as a hook when replacing the pen, and between the fixing arms 2 of the stable pen clamps 1 therebetween. The same hook shape is formed in the end of the fixed arm 7 of the carriage pen holder 4 which is held and coupled.

3 shows the working state of the stable pen clamp 1 and the carriage pen holder 4 at the time of pen replacement.

First, as shown in (a), the carriage pen holder 4 approaches the side of the stable pen clamp 1 to hold the pen for planar drawing.

At this time, as shown in (b), the sliding pin 6 of the rotary arm 5 rotatably arranged in the carriage pen holder 4 pushes the stable pen clamp 3 so that the rotary clamp 3 is the shaft pin ( 3b) rotates clockwise and at the same time, the L-shaped rear surface 3a of the L-shaped rotating clamp 3 pushes the pen toward the carriage pen holder 4, thereby taking over the pen to the carriage pen holder 4 in an instantaneous motion. do.

In this state, the carriage pen holder 4 retreats and the carriage moves in the X Y direction to perform planar drawing.

When the other pen is replaced during drawing, the carriage is brought to the pen replacement position and the operation of taking the pen to the penless stable pen clamp (1) is shown in Fig. (C) (d).

When the carriage pen holder 4 is at rest, the rotating clamp 3 of the stable pen clamp 1 is coupled between the rotary arms 5 of the carriage pen holder 4 while approaching from the side of the stable pen clamp 1. It is connected to the sliding pin (6) of the rotary arm (5) and the table pen clamp moves counterclockwise to the rotation arm (5) of the carriage pen holder (4) until the retained pen is transferred to the stable pen clamp. Expand in the direction.

Accordingly, the pen is completely turned over to the stable pen clamp 1 while pushing the pen held by the N-shaped horizontal end portion 5a of the rotary arm 5.

The features of the present invention as described above can be made compact by replacing the rotary clamp in the cavity of the stable pen clamp and the interaction of the sliding clamp of the stable pen clamp and the sliding pin protruding from the rotating arm of the carriage pen holder. There is an effect that can improve the reliability of the pen replacement operation.

Claims (1)
