Description

Detailed Description of the Invention <Industrial Field of Application> The present invention relates to a pen exchange device for a multi-pen recording device, and more specifically, the present invention relates to a pen exchange device for a multi-pen type recording device, and more specifically, it takes out any one of the plurality of recording pens stored therein and After the operation of
The present invention relates to a pen exchange device for a recording device that stores a recording pen in its original storage position.

<Prior art> Conventionally, automatic exchange devices for recording pens (hereinafter referred to as pens) of recording devices have generally consisted of (a) a pen holder that uses a magnetic material to hold the pen, a movable pen holder, and a storage pen holder. It consists of a holding plate with an opening at 90 degrees, and when taking out a pen from the storage part, the turret that holds the storage part is rotated in advance to a position where the moving part pen holder does not collide with the pen in question. A system in which the pen is automatically exchanged by advancing the moving pen holder to a predetermined position, then reversing the turret to the pen sharing position, retracting the moving pen holder to take out the pen, and retracting the pen through the reverse process. (b) Taking advantage of the fact that the physical position of the tip of the pen pressure holding movable arm provided in the pen holder is different between the pen holding part and the non-pen holding part, the opposing pen pressure holding movable arm is divided. There is a method in which the pen is automatically replaced by changing the pen.

<Problems to be Solved by the Invention> In the above method (A), it is necessary to rotate the turret significantly to avoid collisions on the pen holder side of the moving part, and when replacing a large number of pens, it is necessary to increase the diameter of the turret. Needs to be changed and the pen changing device requires a large space.

In the above method (a), the movable arms for holding pen pressure are inserted into each other, so the arms are left wide open, which causes problems such as wear of the arms and reduction in the elasticity of the springs that elastically support the arms. There is a point.

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a compact and highly reliable automatic pen exchange device.

<Means for Solving the Problems> According to the present invention, a moving part pen holder moves a recording pen in the Y-axis direction, and a storage part pen holder is provided at one end in the Y-axis direction and stores a plurality of recording pens. A recording device comprising a rotatable turret having a turret, the storage pen holder is rotatable at a predetermined angle with respect to a holding plate that rotates together with the turret, and the holding plate is provided with an opening having a pen restraint part,
The pen can be taken out by making the pen holding force of the movable pen holder sufficiently stronger than the pen holding force of the storage pen holder, and the pen can be stored by rotating the turret a predetermined amount with both holders sharing the same pen. Accordingly, there is provided a pen exchange device for a recording device in which a storage part pen holder rotates idly and the pen is restrained by a pen restraint part of a holding plate of a turret, thereby making it possible to store the pen.

<Function> According to the present invention, since the pen holding force of the movable pen holder can be made sufficiently strong, the operation reliability as a recording device is high, and the pen exchange operation between the movable pen holder and the storage pen holder is easy. is reliable, reliable, and has a simple mechanism.

<Embodiment> An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. A rotary disk 3, a turret base 4, and a turret holding plate 5 are rotated as a unit by a motor, for example, a step motor 2. These are positioned and fixed to each other by dowels, set screws, etc. as shown. A cylinder 6 in which a plurality of storage pen holders 7 are provided at angular intervals is attached to the turret base 4 so as to be relatively rotatable, and the amount of relative rotation, that is, idling, is fixed to the turret base 4. It is limited by a pin 9 and a spring 10 connected at one end to the cylinder 6. The turret holding plate 5 has a storage pen holder 7.
A plurality of openings 11 corresponding to the number of openings 11 are provided on the periphery thereof, and each opening 11 is provided with a restraining portion 12, which will be described later. Spring 10 is normally open 1
1 peripheral openings are respectively aligned with the storage pen holders 7. FIG. 2 is a sectional view showing the assembled state.

FIG. 3 shows a pen removal process in which the pen 20 is transferred from the fixed pen holder 7 to the movable pen holder 14, in which the movable pen holder is attached to the pen cartridge 15 that moves in the left-right direction in the figure while being guided by the pen cartridge guide rod 16. 14 moves to the leftmost side, it is held by the fixed part pen holder 14 while being held by the fixed part pen holder 7. This state is shown in FIG. When the pen cartridge 15 moves in the direction of the arrow, the pen holding force of the moving part pen holder 14 is sufficiently greater than the pen holding force of the fixed part pen holder 7, so the pen 20 is released from the fixed part pen holder 7 and moves to the moving part pen holder 14.
Moved to.

FIG. 4 shows the pen storage process, in which the movable pen holder 14 to which the pen 20 is attached moves to the left and assumes a position where it shares the pen 20 with the fixed pen holder 7 shown in FIG. The plate 5 is shown rotated in the direction of arrow B. Since the fixed part pen holder 7 can idle at a predetermined angle with respect to the turret holding plate 5, it remains in the initial position, and the restraining part 12 of the opening 11 assumes the position shown in the drawing. When the pen cartridge 15 moves in the direction of the arrow A, the pen 20 remains held in the stationary pen holder 7 and is forcibly released from the movable pen holder 14.

<Effects of the Invention> As described above, according to the present invention, pen replacement is extremely easy, reliable, and has a simple mechanism, and the pen holding force of the movable pen holder 14 is made sufficiently large during recording. Improve operational reliability.

In addition, the automatic pen exchange device can be made smaller and more reliable, which has the advantage of being of great industrial value.
