Abstract

PURPOSE:To form a paper pattern directly by allowing the direction of the edge part of a cutter attached to a pen carriage to coincide with the moving direction of the cutter by the signal of a microcomputer. CONSTITUTION:A cutter 8 is always pushed up by a push spring 25; and when a contact piece 17 falls against the push spring 25, the cutter 8 falls in accor dance with this fall. The tip of the cutter 8 is formed to an edge part 26, and a paper is cut smoothly in the direction toward which the edge is directed. When a main shaft 18 is rotated, the cutter 8 is rotated together with a sleeve 23, and the moving direction of the cutter 8 is calculated by a microcomputer 20, and simultaneously, the rotation of a cutter motor 5 is so controlled that the edge part 26 is directed to the moving direction. The cutter 8 is moved vertically freely with respect to the sleeve 23 and is rotated together with the sleeve 23. Thus, a form set on a paper bed is cut to an optional shape.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an XY plotter that is connected to a computer to draw figures and the like with a pen, and particularly to an XY plotter that is suitable for creating paper patterns.

[Background of the invention]

Since the pen-drawing XY plotter is based on straight line drawing with a pen, it has traditionally been
Aided ]) is widely used for esign).

The purpose is to draw figures on paper, for example,
When applied to clothing, it is troublesome that the drawn figure must be cut out and made into a paper pattern by another means.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an XY plotter which can overcome the above-mentioned drawbacks and which can also directly create paper patterns.

[Summary of the invention]

In order to achieve such an object, the present invention includes a pen carriage that is equipped with a Paverbets F1 pen for setting paper and that can be moved in conjunction with a motor, an element for raising and lowering the pen, and a pen carriage. In an XY plotter having two motors for moving one or both of the sheets of paper in the X direction or the Y direction and a microcomputer for controlling the movement of each movable element, the pen carriage is capable of cutting the paper. Install a cutter that can
The apparatus is provided with means for aligning the direction of the blade of the cutter with the direction of movement of the cutter based on a signal from the microcomputer.

[Embodiments of the invention]

Hereinafter, one embodiment of the X-Y plotter according to the present invention will be explained in detail using FIGS. 1 to 4. In FIG.
A sheet of paper 1 is placed on a vapor bed 2, and the ends of the sheet of paper 1 are sandwiched between feed rows 23a, 3b arranged on the lower surface and rubber rollers 4a, 4b arranged on the upper surface. The feed rollers 3a and 3b are connected to an X-axis direction drive motor 5, and the paper 1 is rotated by forward and reverse rotation of the motor 5.
is moved in the X-axis direction. - A pen 7 and a cutter 8 are mounted on the sword and pen carriage 6. The rotation of the X-axis direction drive motor 9 is: Motor 7'-IJI
Ol< is transmitted to the pen carriage 6 via the thread 11,
The pen carriage 6 is moved in the X-axis direction. The thread 11 is fixed to the pen carriage 6, and one end is rotatably supported by the idler pulley 12.The pen up/down lever 13 is supported by shafts 14a and 14b at both ends, and controls the up and down action of the core shaft 16 of the solenoid 15. The tip moves up and down within a small angle range. The vertical direction of this tip is transmitted to the pen 7 via the contact piece 17. With this configuration, the pen can move up and down in response to the application of an electric signal to the solenoid 15. A main shaft 18 that guides the movement of the pen carriage 6 is connected to a cutter motor 19 and is rotatable. Depending on whether the contact piece 17 is in contact with the pen 7 or the cutter 8, either drawing a figure with the pen or cutting out with the cutter is selected. The contact piece 17 is switched in detail as shown in FIG. That is, the Y-axis movable range of the pen carriage 6 is divided into a cutting/drawing movement range LA and a switching movement range L++, and the pen carriage 6 has moved to the switching movement range Ls (moved by the operator at the time of switching). At this time, the contact piece 17 comes into contact with the abutment part 40 fixed to the device, and this contact piece is adapted to move from the pen 7 side to the cutter 8 side. Although FIG. M2 is a diagram showing one end side of the main shaft 18, the other end is also provided with a contact portion having the same function as the contact portion 40, and this contact portion allows the contact piece 17 to be is switched from the cutter 8 side to the pen 7 side. The X-axis direction drive motor 5, the X-axis direction drive motor 9, the solenoid 15, and the cutter motor 19 are independently controlled by a microcomputer 20, and the driver 2
1. Signals for controlling each element are sent from an external computer (not shown) having a program for creating predetermined graphics, and are taken into the microcomputer 20 via the I10 section 22t.

Next, a mechanism for aligning the direction of force of the cutter 8 with the direction of movement of the pen will be described. 3(a) is a view of the A-B@ plane of the pen carriage 6 in FIG. 1 viewed from the M direction, and FIG. 3(b) is a view of the pen carriage 6 viewed from the N direction. . In Figures (a) and (b), a sleeve 23 is rotatably attached to the carriage 6, and a retaining ring 24 provided on the sleeve 23 prevents the sleeve 23 from being pulled out downward from the carriage 6. Is going.

The cutter 8 is inserted inside the sleeve 23, and has a structure in which it can move vertically with respect to the sleeve 23, but is prohibited from relative rotational movement. The cutter 8 is constantly pushed up by a push spring 25, and when the contact piece 17 goes down against the push spring 25, the cutter 8 follows and moves down. The tip of the cutter 8 is a blade portion 26, which allows the paper to be smoothly cut in the direction the blade faces.

A worm gear 27 is attached to the main shaft 18 so that it is movable in the axial direction and rotates together with the main shaft 18. That is, main shaft 1
8 is formed with a spline groove 28, and an inner nozzle pin 29 of the worm gear 27 is fitted into this spline groove 28. The worm gear 27 has a sleeve 2
The pinion portions 30 of No. 3 are engaged with each other, and the main shaft 18'! When the sleeve 23 rotates, the cutter 8 rotates together with the sleeve 23. Therefore, the microcomputer 20 can calculate the moving direction of the cutter 8 and at the same time fully control the rotation of the cutter motor 5 so that the blade section 26 faces in that direction.

Here, the shape of the hole in the sleeve 23 is shown in FIG.

A spline groove 31 is formed inside the hole, into which a pin 32 on the side surface of the cutter 8 is fitted. Therefore, although the cutter 8 can freely move up and down relative to the sleeve 23, it rotates together with the sleeve 23.

According to this embodiment, pen writing and cutter cutting can be freely switched using an external computer, the cutter can be easily replaced, and the pen carriage is the only directly moving part and is lightweight, so high-speed movement is possible. It is possible to obtain effects such as being possible.

Furthermore, in this embodiment, the shaft of the guide 18 for moving the carriage 6 is also used as the drive shaft for rotating the cutting edge of the cutter 8, so that the apparatus can be simplified.

FIG. 5 shows another embodiment. Paper bed 2 cutter
An elongated recess 32 in the Y direction is formed in the 8 contact portion. In this way, it is possible to obtain the effect that the paper bed is not damaged by the cutter.

Also, if the paper 1 is made of multiple sheets of paper that are closely attached with adhesive material, and the side in contact with the paper bed is made of relatively thick paper, the paper bed can be prevented from being damaged by the cutter, as in the embodiment shown in Fig. 5 above. The effect is that there is no such thing. Further, an effect can be obtained in that it does not separate into pieces even after cutting.

〔Effect of the invention〕

As described above, according to the present invention, paper patterns and the like can be directly created by cutting the paper set on the vapor bed into an arbitrary shape with a cutter.
