Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper-driven automatic drafting machine that allows a writing implement to be exchanged between a writing implement stocker and a drawing head.

[Conventional technology]

In this type of drawing device, the display of the operation panel is formed to be relatively small, and the display does not display writing instrument information such as the type of writing instrument of the writing instrument stocker.

[Problems to be solved by the invention]

There are different types of writing implement stockers according to each pen type, and the number of pens is set according to use.

However, once the writing instrument stocker has been set in its storage section, the operator can select the type of writing instrument stocker,
In order to check the setting state of the writing implement of the stocker, the cover of the writing implement stocker storage section had to be opened and looked from above, which was extremely inconvenient.

An object of the present invention is to provide a paper-driven automatic drafting machine from which the above-mentioned defect has been eliminated.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a drawing head, a writing implement connected to a rotary drive motor and having a plurality of writing implement holding mechanisms on an outer peripheral portion, the writing implement being rotated by driving the motor and being held by the writing implement holding mechanism. A writing implement stocker that brings a desired writing implement to a transfer position for delivering the drawing implement to the drawing head, and a writing implement stocker storage unit provided to store the writing implement stocker in the body of an automatic drafting machine,
An operation panel for operating an automatic drafting machine, wherein a paper-driven automatic drafting machine configured to mutually exchange writing tools between the drawing head and a desired writing tool holding mechanism of the writing tool stocker; And a display for displaying writing instrument information such as the type of the writing instrument held by the writing instrument holding mechanism of the writing instrument stocker.

[Action]

With the above-described configuration, the writing implement-related information is always displayed on the display, so that the operator does not need to remove the writing implement stocker from its storage part for checking the pen, and the operability is greatly improved.

〔Example〕

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

In FIG. 1, reference numeral 2 denotes a body of a paper-driven automatic drafting machine, on which a Y rail 4 is installed. Boxes 2a and 2b are formed on both sides of the body 2, and a display 3 made of liquid crystal and an operation panel 6 for operating the controller 24 of the drafting machine are arranged on a front panel of one box 2a. .

The inside of the other box 2a forms a writing implement stocker storage section 8, and a cover 10 is fitted on the upper part thereof so as to be openable and closable.

A stepping motor 12 is provided at the bottom of the storage section 8, and a tubular portion of a known writing implement stocker 16 is detachably mounted on a shaft 14 fixed to an output shaft of the stepping motor 12. A plurality of known writing instrument holding mechanisms 18 are formed at equal intervals on the outer periphery of the stocker 16.

A drawing head 20 is attached to the Y-rail 4 so as to be movable along the Y-rail 4, and a pen holder is attached to the drawing head 20.
Numerals 22 are arranged in association with a lifting mechanism built in the head 20.

When the pen holder 22 of the drawing head 20 moves to the writing tool transfer position A of the stocker storage section 8, the writing tool holding mechanism 18 of the stocker 16 at the transfer position and the drawing head 20 move.
It is configured such that writing instruments can be exchanged with the pen holder 22.

Reference numeral 24 denotes a platen on which a sheet 26 is placed and guided. The sheet 26 is formed by a driving roller projecting from a notch of the platen and a pressing roller pressing the sheet onto the driving roller. It is configured to be fed back and forth along 24.

The pen head 20 is driven by a Y motor 28, the driving roller is driven by an X motor 26, and the pen holder 22 is driven by a solenoid 30 in a vertical direction. In the above-described configuration, the display 3 displays (1) the type of the writing instrument stocker 16 and (2) the pencil stocker based on information supplied from various known detectors 32, 34, 36, and 38 to the controller 24. (3) Writing tool type setting in the case of a pen stocker, (4) presence / absence of a writing tool in the writing tool stocker, and presence / absence of a core in the case of a pencil stocker. More than the type of writing implements are displayed.

As shown in FIG. 4, a pen-related display area E including a stocker type display area (E1) and a stocker pen status display area E2 is provided in a part of the display 3.

These types do not always display the stocker-related information. Instead, when the entire display is used by some operation or the like, the display becomes the display, and when the operation is completed, the display returns to the stocker-related display.

 The display of the stocker relation is changed by the following factors.

(1) When the stocker is attached or removed, (2) When they are changed by the operation of the pencil map and pen type setting, (3) When the pen is taken or returned, (4) When the pen stocker is In the case where there is no core, the fourth
In the case of the display shown in the figure, it indicates that the stocker 16 attached to the storage unit 8 is an aqueous ballpoint pen, and the writing implement, that is, the pen is set in the writing implement holding mechanism 18 of the stocker 16 at Nos. ing.

Further, among the pens set in the writing instrument holding mechanism 18, numerals 1 to 3 indicate water-based ball pens, and numerals 7 and 8 indicate ink pens.

The writing implement P taken by the drawing head 20 blinks the number of the writing implement holding mechanism 18 on the stocker 16 side holding the corresponding writing implement, that is, the pen number, without providing a separate display area for the pen head.

Regarding the types of writing instruments, in order to display them in a limited space, as shown in FIG. 4, abbreviations are used for the water-based ballpoint pen and the ink pen, respectively.

The sensor 32 shown in FIG. 3 detects a mark provided on the stocker 16 to detect the type of the stocker 16 and a sensor 34.
Detects the mark M1 formed on the writing implement P and
, The sensor 36 detects the mark M2 of the writing implement P to detect its type, and the sensor 38 detects the presence or absence of the writing implement.

The origin position of the stocker 16 is configured to be detected by a sensor 40.

The various sensors are provided on the stocker storage unit 8 side.

The sensor may have various configurations, and the present invention is not particularly limited to the sensor.

〔effect〕

Since the present invention is configured as described above, the state of the writing instrument stocker can be checked on the display without adding hardware, and therefore, the operator does not need to take out the writing instrument stocker from the storage unit and without any special operation. Since the stocker state can be grasped, there is an effect that operability is extremely improved.
