As shown in FIG. 3 and FIG. 4, the automatic roll cutting device of the present invention comprises an outer cylinder 10 which can be mounted with a roll-shaped tape 30 at the rear and which has an outer appearance, and a disc 41 located at the upper end of the outer cylinder 10 side. The rotatably coupled rotating assembly 40 is attached to the safety cover 12 of the outer cylinder 10, and is located inside the outer cylinder 10 covered by the safety cover 12, and performs a reciprocating rotation in the front-rear direction and a cutting operation of the winding tape cutting operation. The machine 20 is located inside the outer cylinder 10 and is provided with a click M for providing power, and a printed circuit board 18 having a microprocessor that is located inside the outer cylinder 10 and controls the overall operation of the rolled tape cutting device.

The roll-shaped tape automatic cutting device having the above structure is mounted on the rear side of the safety cover 12 of the outer cylinder 10, and the roll-shaped tape 30 is attached, and one end of the roll-shaped tape 30 is taken out and passed through the tape located at the cutter 20. The insertion port 20a is attached to a disk 41 rotatably driven at the upper end of the outer cylinder 10. Then, when the operation button 19 located at the center of the disk 41 is pushed, the motor M inside the outer cylinder 10 is operated, the cutter 20 is repeatedly rotated in the front-rear direction, and the cutting operation is performed, and the roll tape 30 is pressed to a certain length. The cutting is performed so that the cut tape 31 is attached to the disk 41 at regular intervals to provide the cut tape 31 to the user.

Next, an electric roll tape cutting device having the above structure will be described in detail.

First, as shown in Figs. 3 and 4, one side of the outer cylinder 10 has a cylindrical main body structure, and the rotary assembly 40 is assembled to the structure, and the disk 41 is rotatably provided. Inside the outer cylinder 10 corresponding to the lower side of the rotary assembly 40, a motor M for supplying power and a printed circuit board 18 having a microprocessor and controlling the operation of the entire roll tape cutting device are arranged side by side.

Further, on the other side inside the outer cylinder 10, a cutter 20 driven by the motor M and the gear assembly 17 is provided, and the upper portion of the cutter 20 is attached to the outer cylinder 10 by the mounting boss 12a. A safety cover 12 is embedded in the edge line for preventing a safety accident of the cutting machine 20.

The electric roll-shaped tape automatic cutting device of the present invention employs a structure in which the cutting operation can be continuously and automatically performed only by mounting the above-described safety cover 12.

As shown in FIG. 3 and FIG. 4, the inner peripheral surface of the outer cylinder 10 in which the above-described safety cover 12 mounting boss 12a is fitted is provided with the mounting protrusion 12a of the safety cover 12 pressed or not, and the safety cover 12 is sensed. The contact sensor 11 is installed or not. The above-described contact sensor 11 senses the attachment or detachment of the safety cover 12 in a contact manner, and determines whether the circuit is disconnected or turned on by the microprocessor of the printed circuit board 18 in accordance with such contact. The printed circuit board 18 selectively controls the manual or automatic mode of the roll-to-tape cutting operation in accordance with the above determination.

That is, the printed circuit board 18 allows the cutter 20 to continuously perform the automatic cutting operation of the rolled tape or the manual operation of the user to press the operation button 19 every time, depending on whether the safety cover 12 is attached or not.

For example, when the safety cover 12 is attached, the contact sensor 11 is pressed and the mounting state of the safety cover 12 is sensed, and even if the cutting machine 20 performs a continuous cutting operation, a safety accident can be prevented, so that only the above-mentioned action button is pressed once. 19, the cutting operation of the rolled tape 30 can be automatically performed continuously by the control of the printed circuit board 18 in the set range.

That is, with the conventional mechanical roll-shaped tape automatic cutting device, when the above-described safety cover 12 is not mounted, the main power source is cut, and the roll-shaped tape automatic cutting device cannot be driven at all. However, in the present invention, even if the above-described safety cover 12 is not attached, the main power source is not turned off, but only the continuous automatic control signal is turned off. Therefore, the user can perform a manual cutting operation by the cutter 20 by pressing the action button 19 once.

As shown in Fig. 4, the cutter 20 includes an upper blade portion 21 located at an upper portion of the cutter main body, and a lower blade portion 22 corresponding to the upper blade portion 21 at a lower portion thereof in contact with the top surface of the lower blade portion 22. The assembled blade drive plate 26 presses and fixes the roll tape 30 when the roll tape 30 is inserted into the roll tape insertion opening 20a in a state where the roll tape 30 is moved to the direction of the disk 41 to be pasted or cut. The roll-shaped tape pressing plate 25 that prevents the roll-shaped tape 30 from being shaken is provided under the upper blade portion 21 and the lower blade portion 22, the blade drive plate 26, and the roll-shaped tape pressing plate 25 by the cam shaft 24, and is driven by the driving of the cam. The machine 20 performs a cam assembly 23 for the cutting operation.

The cutter 20 having the above-described configuration moves to the rear side of the disk 41 around the cam shaft 24 by the driving of the motor M, and moves in the direction of the disk 41 in accordance with the activation of the gear assembly 17. In the process of repeating the above operation, the blade edge of the upper blade portion 21 and the blade edge of the lower blade portion 22 are interlaced, and the rolled tape 30 attached to the disk 41 is cut to a predetermined length.

On the outer side of the outer cylinder 10, a cutter moving distance adjusting knob 14 and a disc for adjusting the moving distance in the front-rear direction of the cutter 20 (the same cutting distance as the rolled tape) and the rotational distance of the disk 41 are provided. Rotate the distance adjustment knob 13.

Here, the mechanical construction principle of the cutter 20 moving distance adjustment knob 14 is adjusted in the front-rear direction of the cutting machine 20 (the same cutting distance as the roll-shaped tape), and the utility model application number 374488 which the applicant of the present invention has applied for in Korea. No. (2005.1.19 application, name: tape cutting distance adjusting device of the automatic tape cutting device), and the mechanical construction principle of adjusting the rotational distance of the disk 41 by the above-described disk rotation distance adjusting knob 15 and the applicant of the present invention The utility model application No. 374489 (2005.1.19 application filed in Korea, the name: the rotational distance adjusting device for feeding the disc with a tape-shaped tape automatic cutting device) is the same. Therefore, the detailed description of the specific structure and working principle is omitted.

Further, in the electric roll-shaped tape automatic cutting device of the present invention, a printed circuit board 18 is provided inside the outer tube 10. The printed circuit board 18 has a microprocessor in which a program for continuous cutting operation is stored. Therefore, the user can press the cutter button 20 once, and the cutter 20 can continuously perform the cutting operation in accordance with the set range (the rotation distance of the disk 41 is set in advance).

The prior art mechanical roll-shaped tape automatic cutting device requires the user to press the button each time, the cutting machine correspondingly cuts the roll-shaped tape, rotates the disk according to the set rotation distance, and sequentially pastes the cut roll-shaped tape. Compared with this prior art semi-automatic working structure, the present invention can greatly improve the convenience in use.

That is, the printed circuit board 18 receives the signal selected by the user according to the programmed program, and performs overall control of the cutting operation of the rolled tape 30, thereby eliminating the cumbersomeness of the manual operation for the user.

Next, a configuration of the rotary assembly 40 of the present invention which allows the disk 41 to continuously rotate automatically will be described with reference to Figs. 5 and 6 .

The rotating assembly 40 includes an assembly body 42 that is assembled on the upper cylindrical outer cylinder 10 of the motor M by means of a projection insert assembly, and is inserted and assembled along the inner side of the assembly body 42 and rotatably located in the outer cylinder. The upper end disc 41 is rotatably connected to the inside of the assembly main body 42 and is coupled to the outer peripheral surface of the central extending portion of the disc 41 by a gear transmission structure and a rotatable disc 41. At the same time as the lower end of the gear rotating portion 44, the rotary lever 45 is mechanically coupled to the cutter 20 and the disk rotation distance adjusting knob 13, and is rotatable in accordance with the reciprocating distance of the cutter 20 in the front-rear direction.

Here, the interlocking structure between the above-described rotating lever 45 and the cutter 20 and the disk rotation distance adjusting knob 13 is constituted by a connecting hole 45a at one end of the rotating lever 45 by means of another connecting structure (not shown).

The rotary lever 45 is interlocked with the cutter by a mechanical structure, and is repeatedly rotated clockwise and counterclockwise together with the gear rotating portion 44, so that the disk 41 can be rotated at a set rotational distance.

Further, on the upper circumferential surface of the outer cylinder 10 corresponding to the lower side of the bottom surface of the disk 41, an automatic sensor 16 which can be changed by the user through the guide rail 10a is provided.

The automatic sensor 16 senses the cut roll tape 31 that rotates together with the disk 41, and limits the rotation distance of the disk 41, so that the disk 41 and the cutter 20 can temporarily interrupt the operation, and the user changes The position of the automatic sensor 16 can limit the rotational distance of the disk 41.

Here, as shown in the figure, the automatic sensor 16 is assembled inside the assembly body 42 by the rotation support 16a, and is rotatable along the guide rail 10a at the upper end of the outer cylinder 10.

An action button 19 is slidably provided by the assembly ring 43 on the inner side of the extending portion formed downward from the central portion where the disk 41 of the rotary assembly 40 is open.

The operation button 19 is a button that issues a rotation operation of the disk 41 and a cutting operation start command of the cutter 20 in a state where the main power source is turned on. At the lower end of the operation button 19, an operation signal for receiving the operation button 19 and an auxiliary substrate 46 having a tap switch for transmitting a control signal to the printed circuit board 18 are provided.

In other words, the contact portion 19a supporting the lower end of the operation button 19 is brought into contact with the branch switch of the auxiliary board 46 to emit an operation signal.

Further, although not shown, a light-emitting element such as a light-emitting diode (LED) can be inserted into the internal space of the contact portion 19a to improve the appearance of the operation button 19.

The power source of the above-described light-emitting element can be provided by a circuit formed on the auxiliary substrate 46.

Next, the principle of operation of cutting the roll-shaped tape 30 of the electric roll-shaped tape automatic cutting device of the present invention will be described.

First, as shown in FIG. 7, on the rear side of the outer cylinder 10, a roll-shaped tape 30 to be cut and supplied is attached, and the one end of the roll-shaped tape 30 is taken out in a state where the safety cover 12 is covered, and inserted into the cutting. The roll-shaped tape of the machine 20 is inserted into the opening 20a.

Thereafter, the main power switch 15 located on the outer peripheral surface side of the outer cylinder 10 is turned on, and the power is turned on.

Of course, before the power is turned on by the main power switch 15, the cutting distance adjustment knob 14 and the disk rotation distance adjusting knob 13 are first moved by the cutter to set the cutting distance of the rolled tape 30 and the rotation distance of the disk 41.

When the operation button 19 at the center of the disk 41 is pressed and the operation signal is turned on while the power is turned on, the motor M inside the outer cylinder 10 starts to be driven, and the gear assembly connected to the cam shaft 46 at the lower end of the cutter 20 is driven. With 17 drives, the cutter 20 starts working. Here, the cutter rotates in conjunction with the cam of the cam assembly 40 to sequentially perform the cutting operation and the movement in the front-rear direction, and when the cutter 20 is sequentially operated, the disk 41 connected thereto is rotated in synchronization.

In other words, as shown in FIG. 7 to FIG. 9 , when the cutter 20 performs the reciprocating operation in the front-rear direction with respect to the disk 41, the cutting operation of the roll tape 30 is completed once, and the disk 41 to which the cut tape 31 is pasted is attached. Also rotate once at the set rotation distance.

Here, the cutter 20 moves to the rear side of the cam shaft 24 as the motor M is driven, and then moves in the direction of the disk 41. In the process of repeating the above operation, the cutter 20 affixes the roll tape 30 to the disk 41 in the state shown in Fig. 8, and cuts the roll tape 30 by a predetermined length in the state shown in Fig. 9.

That is, as shown in Fig. 8, the cutter 20 attaches the end of the rolled tape 30 to the disk 41, and as shown in Fig. 9, the cutter 20 cuts the rolled tape 30 while moving to the rear side.

Of course, as shown in Fig. 9, when the cutter 20 is moved rearward, the moving distance is the same as the cutter moving distance (the same cutting distance as the roll tape) set by the cutter moving distance adjusting knob 14.

Then, as shown in FIG. 8, the cutter 20 is moved in the direction of the disk 41 in a state where the roll tape 30 is fixed, and the end of the roll tape 30 is attached to the disk 41 again.

In this process, the disk 41 rotates to the rotational distance set by the disk rotation distance adjustment button 13 in accordance with the movement of the cutter 20 and the linkage therewith.

That is, the first cut tape is rotated together with the disk 41 to another position, and the end of the roll tape 30 is re-attached to the portion of the disk 41 that is in contact with the cutter 20.

Further, the present invention has a contact sensor 11 that senses whether or not the above-described safety cover 12 is attached in a contact manner. Therefore, according to the attachment or detachment of the safety cover, the continuous automatic cutting operation of the roll-shaped tape can be performed, and the manual cutting operation of the roll-shaped tape can be performed, and the roll-shaped tape 30 can be cut one by one by the user.

Further, in the present invention, the outer peripheral surface of the upper end of the outer cylinder 10 corresponding to the lower side of the disk is provided with a position which can be adjusted by the user, the position of the cut-and-rolled tape 31 which can be rotationally moved, and the total rotation of the disk 41 can be restricted. Automatic sensor 16 for distance. When the cutter 20 repeats the front-rear movement operation and the cutting operation and the disk 41 is continuously rotated, the cutter 20 and the disk 41 are temporarily interrupted in accordance with the setting of the user and the rotation distance of the restriction disk 41.

That is, when the cut tape 31 pasted on the disk 41 is moved to the position where the automatic sensor 16 is located, the automatic sensor 16 senses the situation and sends a sensing signal, and the printed circuit board according to the signal allows The cutter 41 is suspended while the cutter 41 is suspended.

When the user peels off the cut tape 31 at the position where the automatic sensor 16 is located, the cutter 20 and the disk 41 are restarted to perform the cutting operation of the rolled tape 30 and the supply of the cut roll tape 31. .
