Abstract

PURPOSE:To perform a smooth operation to replace a pen, by a method wherein microswitches for identifying the presence of a pen are mounted in the proximity of a stationary pen holder and a moving pen holder, and the pen is replaced after confirming the presence of the pen. CONSTITUTION:Microswitches 18 and 21 for identifying the presence of a pen are located in the proximity of a stationary pen holder 6 and a moving pen holder 12, and the presence of a pen of each holder portion is detected by means of the switch 18 and a slit detector 26 for storing. According to a command to attach a recording pen 10, in which it is confirmed that the pen is present, to the unoccupied holder 12, the holder 12 moves in a direction A and reaches a coincidence point. Then, the pen, being unpresent, is confirmed by the microswitch 21. The holder 6 turns by 45 deg. in a direction D to deliver the pen to the holder 12, and the holder 12 moves in a direction B to perform a recording. This confirms the presence of the pen and prevents impingement of the pens with each other, which results in performing a smooth replacement.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pen changing device for a recorder, which comprises a fixed position pen holder that holds a plurality of recording pens, and a movable pen holder that is held in the fixed position pen holder and that exchanges a Kuki Kama pen. .

FIG. 1 is a perspective view of a main part of a recording needle having this type of pen changing device. In the figure, a recording paper 1 is wound around a drum 2 via a sprocket 3 and is tightly attached by a recording paper presser 4. As shown in FIG. Further, the recording paper 1 is driven in the X-axis direction (temporarily referred to as the X-axis direction) by a Nords motor (not shown) K via the drive shaft 5 of the drum 2. The recording pen 10 is attached to the carriage 11 via a movable pen holder 12, and is driven in the Y-axis direction by a wire 16 that transmits the output of a Nolls motor (not shown) and guide shafts 14 and 15.

The fixed-position pen holder 6 holds a plurality of recording pens lO,
It is supported in a fixed position by the support fitting 7. At this time,
The fixed-position pen holder 6 has a rotatable structure, and its drive shaft 8 is connected to a Norms motor (not shown) K. The rotational movement of the fixed position ben holder 60 is therefore controlled by commands of an internal electrical circuit (not shown). Also, at this time, the surface of the recording pen 100 is partially or mostly covered with a magnetic material, and the magnet 9 of the fixed position pen holder 6
The interaction with the magnet 13 of the movable pen holder 12 forms a magnetic mechanism. By this magnetic mechanism, the recording pen lO is attracted and held by the fixed position pen holder 6 and the movable pen holder 12.

Next, the operation will be explained. First, in response to a recording command from an internal electric circuit (not shown), the recording pen 10 held in the pen holder 12 of the moving part 12 records on the recording paper l within the effective recording range. ? :, the pen at ζ, and the recording pen lO of the movable part pen holder 12 reaches the matching point with the vacant pen holder of the fixed position pen holder 6 (FIG. 1). This matching point is the center of the notch forming each pen holding part of the fixed position pen holder 6 and the pen of the movable pen holder 120. Furthermore, the pen holding portion of the one fixed position pen holder 6 and the pen holding portion of the movable pen holder 12 are configured so that their rounded positions are shifted to avoid collision.

Now, when the recording pen 10 on the movable pen holder 12 reaches the matching point, the fixed position pen holder 6 moves in the direction of arrow C (in the fixed position pen holder 6 having four recording pens 10 in this embodiment →
Rotate 45°. This angle of 45° is an angle at which the fixed-position pen holder 6 and the movable pen holder 6 do not collide.

At this time, at the matching point, the directionality of the pen holding part of the fixed position pen holder 6 and the directionality of the pen holding part of the movable pen holder 12 match, and the directionality of the matching point is the same as the direction of the arrow O, so the movement is made. The recording pen IO held in the pen holder 12 is captured by an empty holding portion of the fixed position pen holder 6.

The movable pen holder 12 that has captured the recording pen 10 is driven in the direction of arrow B by the carriage IIK. During this period, the fixed position pen system, D6, moves the pen holder holding the desired recording pen lO from the matching point to the arrow C according to the internal electric circuit command.
Stop at a position rotated 45° in the direction.

Once this is completed, the empty movable pen holder 12
moves in the direction of arrow A to the matching point. Here, the fixed position pen holder 6 is rotated by 45 degrees in the direction of the arrow (FIG. 1).

When the movable pen holder 12 moves from the carriage IIK in the direction of arrow B, K takes over a desired recording pen and performs necessary recording.

However, in this type of pen exchange device, the recording pen 1
Since the attachment and detachment of the 0 was not confirmed, the following problems occurred.

1. Without checking whether the recording pen 10 is held in the movable pen holder 12, the operator waits w4 and attaches the recording pen 10 to the movable pen holder 121C even though the pen replacements 10 have been completed. The above-mentioned inconveniences occurred when the pen was replaced.

In addition, after the pen replacement operation is completed, if it is not checked whether the recording pen 10 is securely held in the movable pen slip holder 12, the recording pen 10 will not be held and the operation will proceed to the dispensing operation, resulting in a large amount of recording loss time. There was a drawback.

2) When using many types of recording pens 10, it is necessary to manually adjust the optimal pen pressure, pen speed, etc. for the recording pen 10 each time the recording pen 10 is replaced. It had some annoying flaws.

In view of these points, Honda filed a patent application in 1986-119.
No. 814 (filed on September 1, 1981, hereinafter referred to as the "prior application"), the presence or absence and type of a recording pen can be determined by providing a reflective mark on each pen holder (in the specification of the present application, a fixed position pen holder) in the storage section. It is described that the detection output is used for pen exchange operation, pen pressure control, etc.

However, in this prior application, the number of detection devices required is equal to the number of recording pens, which not only increases costs but also has the disadvantage of complicating the configuration.

The present invention eliminates these drawbacks and achieves the following objects.

1. To provide a recording needle pen exchange device that smoothly performs a pen exchange operation.

2. To provide a pen exchange device for a recorder capable of automatically controlling pen pressure, pen speed, etc. even when many types of recording pens 10 are used.

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

FIG. 2 is a perspective view showing an example of the recording pen 10 applied to the present invention. The pen shaft at the tip of the recording pen 10 is used as the physical structure for identifying the presence or absence of a pen in the shaft of the recording pen 100, and the movable pen holder 2, . . . , 1), .

The pen shaft body at the end of the recording pen 10 is used as the physical structure for identifying whether the recording pen 10 is attached or not. The convex portion 16 is used as the physical structure for pen type identification.

FIG. 3 is a perspective view of essential parts of an embodiment of the present invention. 1st
In the recorder pen changing device shown in the figure, a microswitch 18 for identifying the presence or absence of a pen and a microswitch 19 for detecting the type of pen are provided near the fixed-position pen holder. Both detection devices are attached to a housing (not shown) using a support fitting 20.

Further, a pen-attached non-detection microswitch 21 is provided along the trajectory of the movable pen holder 12. This detection device 21
is attached to the housing by a support fitting 23.

Furthermore, these detection devices are equipped with internal electrical circuits (diagrams, not shown).
is connected to the storage device. This storage device is a detection device installed on the drive shaft 8 of the fixed position pen holder 6.
This slit detection device is synchronized with the dpi storage device. Next, the operation will be explained. First, the operation for detecting the presence or absence and type of the recording pen 10 attached to the fixed position holder 6 will be explained.

This operation is performed at power-on or initialization.

The fixed-position pen holder 6 is rotated in a fixed direction by its drive shaft 8. At this time, the storage device operates according to the slit detection signal. Here, each pen holding portion of the temporary DK fixed position pen holder 6 corresponding to the slit 24 is designated as a,
in the direction of rotation, c.

Let it be d. First, regarding the pen holding portion aK, the pen presence/absence detecting device 18 detects that the recording pen 10 is being held, and at the same time, the pen type detecting device 19 detects the pen type (presence/absence of the convex portion 16). Similarly, the pen holding parts S, C, and D are also detected and stored in the storage device as follows.Detection device 18) (Detection device 19) a 1 1b
1 0 Cl l d Q 03 ζ Here, l is detected by the detection device 18, IIC, and C1O
This is something that was not detected.

When the storage of the recording pen 10 attached to the fixed position pen holder 6 is completed in this manner, an instruction to attach the recording pen 10 on the pen holder neck is sent to the internal electric circuit, for example, when the pen holder 6 is in a vacant position. It is taken out to the pen holder 12.

In response to this, the movable pen holder 12. moves from the right side z of the drawing in the left direction toward the pen holding part 6 of the fixed position pen holder 6. (At this time, if the recording pen 1'0 is attached to the movable pen holder 12, the rear shaft of the recording pen 10 will disconnect the pen presence/absence detection microswitch 21 of the movable pen holder 12, which will issue an alarm and record the pen 1
(The configuration is such that a new command is issued to attach 0 to the vacant pen holder dK). When the recording pen 10 of the pen holder is attached to the vacant movable pen holder 12, the movable pen holder 6 moves in the opposite direction to perform recording. (If the recording pen 10 is not attached to the movable pen holder 6 at the time of release, it will not be detected by the pen presence/absence detection device 21, so the configuration is such that an !IN notification is generated).

A similar operation is performed when the recording pen 10 attached to the movable pen holder 12 is returned to an empty pen holding portion of the fixed position pen holder 6.

FIG. 4 is a flowchart showing this pen exchange operation.

Also, at this time, the internal electric circuit is connected to the pen type detection device 19.
By providing a control circuit for controlling the pen pressure and pen speed according to the pen tilt stored in the storage device, the optimum pen pressure and speed are provided.

As described above, the present invention has the following effects.

1. During the pen exchange operation, collisions between the recording pens 1011tl and 1011tl are avoided, and the recording pen 10 is checked each time each pen exchange operation is completed, so that the pen exchange can be performed smoothly. An exchange operation is performed.

2. Automatic control of pen pressure, pen speed, etc. is now possible in a recorder that uses many types of recording pens and performs pen exchange operations.

In this embodiment, the physical structure for identifying the presence or absence of a pen and the physical structure for identifying the pen type are configured by the pen shaft and the convex portion 16 provided on the pen shaft.
A similar effect can be obtained by detecting a change in shape using a concave portion such as a cut or a convex portion such as a convex portion. Also,
Rather than utilizing such a change in shape, other physical means such as the reflective mark and light beam described in the prior application are used.

Also, in this embodiment, the movable pen holder: j, 1
Although the 12 pen presence/absence detection devices are provided along the movable pen holder 12, they may be provided on the movable pen holder 12 itself.
