Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cutting plotter for cutting adhesive paper of a cutting sheet, and particularly relates to a cutting sheet mounting device.

[Prior Art] Conventionally, as an apparatus for cutting adhesive paper of a cutting sheet in which a release paper is laminated on the adhesive side of adhesive paper having an adhesive layer on the inside, there is, for example, a device disclosed in Japanese Patent Application Laid-open No. 1983
A cutting plotter described in Japanese Patent No. 300892 is known. The conventional cutting plotter is
A platen roller rotated by a motor is provided in the main body, and a slide rail is fixedly attached to the upper surface of the main body, so that the tool head of the cutter is disposed so as to be movable along the slide rail. In addition, pressure rollers are provided on both the front and rear of the platen roller, and the pressure rollers are placed on the left and right (Y) sides of the platen roller.
direction) so as to be able to be contacted with the main body. Then, to attach the cutting sheet, the cutting sheet is pulled out from the gap between the cutter and the platen roller, and the cutting sheet is clamped between the respective presser rollers and the platen roller. The cutting sheet is brought into close contact with the platen roller due to pressure between the front and rear pressure rollers, and the rotation of the platen roller causes the cutting sheet to move freely back and forth (in the X direction), and the tool head can be moved left and right. While moving in the Y direction, the cutter cuts the adhesive paper of the cutting sheet into predetermined characters, symbols, etc.

[Problems to be solved by the invention] The conventional cutting plotter mentioned above has problems with the clearance between the cutter and the platen roller when pulling the cutting sheet forward from the gap between the main body provided with the platen roller and the cutter of the tool head. Since the cutting sheet is small, there is a risk that the cutting sheet may come into contact with the cutter and damage the surface. Therefore, it is necessary to once remove the cutter, move the presser roller away from the platen roller, and insert the cutting sheet between the platen roller and the presser roller.

Furthermore, the gaps between the main body and the slide tool, between the press roller and the tool head, between the platen roller and the press roller, etc. are narrow, making it difficult to set the cutting sheet through these gaps.

Therefore, a technical problem arises that needs to be solved in order to prevent the sheet from coming into contact with the cutter when the cutting sheet is installed, and to facilitate the installation of the sheet.The present invention solves this problem. The purpose is to solve the problem.

[Means for Solving the Problems] This invention was proposed to achieve the above object, and consists of a roll-shaped cutter with a release paper on the adhesive side of adhesive paper having an adhesive layer on the inside. In a cutting plotter, the cutting sheet is moved in the X direction by a sprocket foil, and the tool head is moved in the Y direction to cut the adhesive paper of the cutting sheet. A lid body that can be opened and closed is provided on the top surface of the main body provided with the rollers, and a slide rail, a tool head that is movable on the slide rail, and a press roller that comes into contact with the sprocket foil are attached to the lid body. It is an object of the present invention to provide a sheet mounting device for a cutting plotter.

[Function] In this invention, the cutter head, press roller, etc. are attached to the lid, so that they can be opened and closed integrally with the lid. Therefore, by flipping the lid upward to open it, the platen roller of the main body is exposed, making it extremely easy to attach the cutting sheet. Furthermore, since the cutter head is flipped up when the cutting sheet is attached, there is no risk of damage to the cutting sheet by the cutter. Then, when the lid is pulled down, the clearance between the cutter and the platen returns to its initial state, and at the same time,
Each pressing roller and arm can be set in a predetermined position, and the cutting sheet can be attached with one touch.

[Example] Hereinafter, an example of this invention will be described in detail with reference to the attached drawings. 1 and 2 show the main parts of a cutting plotter. A platen roller 2 is pivotally attached to the approximate center of a main body 1, and its left and right ends (the direction of arrow Y in the figure is the horizontal direction). The sprocket wheels 3, 3 are fitted on the sprocket wheels. The platen roller 2 is driven by a stepping motor 5 via a pulley 4, and feeds a cutting sheet 6, which will be described later, in the front and back direction (in the direction of arrow X in the figure). Reference numeral 7 denotes a guide plate for sheet feeding, and the guide plate 7 is located at the front and back positions of the platen roller 2.
is bent downward to form recesses 8, 8 below the top of the platen roller 2 and the flat surface of the guide plate 7. Incidentally, reference numeral 9 is a switch for detecting the presence or absence of the cutting sheet 6.

On the other hand, a lid body 10 is mounted on the top surface of the main body 1,
The lid 10 is formed so that it can be opened and closed up and down with the pin 11 as the center of rotation. A slide rail 12 is fixed to the rear of the lid 10, and a moving mechanism (not shown) is provided to the slide rail 12, so that the tool head 13 is provided so as to be movable in the left-right direction (Y direction). The tool head 13 is provided with an arm portion 15 on which a cutting tool 14 is attached, and the arm portion 15 and the cutting tool 14 are configured to be vertically movable by a lifting mechanism 16. The tool head 13 is movable in the left-right direction (Y direction) by a stepping motor 17 via a moving mechanism. The tool head 13 is movable in the left-right direction (Y direction) by a stepping motor 17 via a moving mechanism. The upper surface of the central portion of the lid body 10 is open, and the cutter 18 of the cutting tool 14 is positioned on the top of the platen roller 2 pivotally attached to the main body 1.

The lid body 10 is located above the sprocket wheels 3, 3, and pressure rollers 19, 19, 19, 1 are provided at the front and back positions of the top of the sprocket wheels 3.
9 are pivotally mounted, and each presser roller 19 is formed so as to come into contact with the sprocket foil 3. Further, cylindrical arms 20, 20 are installed in the left-right direction at a constant distance from the recesses 8, 8 of the guide plate 7. Furthermore, the front arm 20 is made rotatable,
A hook 21 is fixedly attached to the left side of the lid body 10 and is vertically attached to the lower surface of the lid body 10. The hook 21 engages with a locking piece 23 fixed on the main body 1 side by tension of a spring 22, and the lid 10 comes into contact with the upper surface of the main body 1, thereby reducing the clearance between the cutter 18 and the platen roller 2. is the initial state.

A storage section 25 in which receiving rollers 24, 24 are pivotally mounted is provided at the rear of the main body 1, and a cutting sheet 6 wound into a roll is placed in the storage section 25. The cutting sheet 6 is wound by laminating adhesive paper on the outside of the roll and release paper on the inside of the roll, and the adhesive paper is made of films such as vinyl chloride coated with various colors.

Next, the procedure for attaching the cutting sheet 6 will be explained. First, the lever 26 protruding from the top of the lid 10 is pushed rearward to release the engagement between the hook 21 and the locking piece 23, and the front part of the lid 10 is lifted upward. Then, as shown in FIG. 3, the lid 10 is flipped upward about the pin 11. As mentioned above, since the tool head 13, press rollers 19, 19, 19, 19, arms 20, 20, etc. are attached to the lid 10, these parts are also attached to the lid 10.
move upwards. Therefore, there are no parts on the upper surface of the guide plate 7 of the main body 1, and the platen roller 2 is exposed. Then, the cutting sheet 6 is spread on the surface of the platen roller 2. As shown in FIG. 2, feed holes 27, 27, . 3.

Then, while pressing the lever 26 again, close the lid 1.
0, and as shown in FIG. 4, engage the hook 21 with the locking piece 23 to lock the lid 10 in contact with the upper surface of the main body 1. In this way, the cutter 18 is set in its initial state with a predetermined clearance from the top of the platen roller 2. At that time, the left and right pressing rollers 19, 19, 19,
19 presses both left and right ends of the cutting sheet 6 engaged with the sprocket wheels 3, 3, and prevents the feed holes 27, 27, . . . from floating up and coming off from the sprocket wheels 3, 3. At the same time, the arms 20, 20 move into the recess 8 of the guide plate 7,
8, the cutting sheet 6 is pushed up slightly, and the cutting sheet 6 is bent downward within the respective recesses 8, 8. Therefore, the curling of the cutting sheet 6 is corrected, and the cutting sheet 6 is brought into close contact with the curved surface of the platen roller 2.

In this way, the cutting sheet 6 is attached to the cutting programmer, and the cutter 18 is operated by the control signal of the cutting program set separately.
descends and contacts the adhesive paper of the cutting sheet 6. Further, the stepping motors 5 and 14 are also energized, and the cutter head 13 is moved left and right (in the X direction).
As it moves, the platen roller 2 rotates forward or backward, and the cutting sheet 6 rotates back and forth (in the Y direction).
The cutter 18 cuts the adhesive paper of the cutting sheet 6 into predetermined characters, symbols, etc.

It should be noted that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to those modifications.

[Effects of the invention] As detailed in the above-mentioned embodiment, this invention allows the cutter head, presser roller, etc. to be opened and closed integrally with the lid, so that when the lid is flipped up, the platen roller is exposed. This makes it extremely easy to attach the cutting sheet. Furthermore, since the cutter head is flipped up when the cutting sheet is attached, the cutting sheet does not come into contact with the cutter, eliminating the risk of damaging the adhesive paper of the cutting sheet. When the lid is pulled up, the clearance between the cutter and the platen is set to the initial state, and at the same time, the respective presser rollers and arms can be set in their predetermined positions, and the cutting sheet can be attached with a single touch. This is a valuable idea.
