Description

Laminator with Sedan {Laminator having the shredder}

The present invention relates to a laminator having a document shredding function in which a document shredder is added to a laminator that coats the document with a transparent film. A drive device for integrating and selectively driving the same.

In general, the laminator is a coating device for protecting the document by coating the surface of the paper (hereinafter referred to as the document) with a transparent film is mainly used for long-term storage by coating students' stationery or photos of daily life. Such laminators are now widely used in various fields, and are also widely used in general offices.

On the other hand, document shredder refers to a device that finely shreds document shredders and cardboard boxes and waste paper for the purpose of recycling or discarding documents or transaction documents and micro films that require security in offices or banks. Inventions are more effective at breaking documents, microfilm bills, or other papers that require security.

In this way, the laminator and document shredder which are one in the office equipment are manufactured independently and installed separately. In the past, office equipment such as facsimile machines and copier scanners all had independent functions (one function) .In recent years, for example, facsimile machines, copiers, and scanners that have multiple functions in one machine are integrated into one machine. (Called a multifunction device).

Such a multifunction device not only overcomes the space constraints occupied by office equipment when the office or indoor space is small, but also lowers the manufacturing cost of the office equipment and provides a more convenient and convenient user effect.

As described above, the present invention integrates a laminator and a document shredder to reduce manufacturing costs by multiplying functions by integrating independently configured laminators and document shredders, and integrates a sedan function with a laminator so as to reduce an installation space. To provide a driving device for integrating the drive to perform both functions with a single drive motor.

To integrate laminators with document semantics, they must have the necessary functions to perform their respective functions and solve the problem of minimizing their components.

Therefore, in order to solve this problem, the components of the existing document shredder and laminator are examined, and the configuration to minimize the components is examined.

First, document shredder registered utility model No. 0298640 (registration date: 12/09/2002) "document shredder" and utility model registration No. 0292643 (registration date: 10/08/2002) "document shredder cutter shaft power transmission structure" It is disclosed in detail.

According to the above-mentioned document shredder, two disc-shaped blades are supported to alternately engage each other so that the cutters for the cutters intersect with each other so that the driven gear is transferred to the disc-shaped blade when the drive motor rotates. It can be seen that the power is coupled to the blade shaft.

Therefore, the document shredder operates two disc-shaped blades which rotate in an alternately engaged state, power generating means for providing rotational force, power connecting means for connecting power, and the power generating means for implementing the function. And a switch for stopping.

On the other hand, the laminator is configured such that when the main power switch is turned to the ON position, the driving motor is operated so that a pair of driving rollers are engaged and rotated, and the coating film is fused by heat while the original passes between the pressurized rollers heated to high temperature.

Therefore, the laminator operates the main power switch during the laminating operation, and after a few seconds, the film is sandwiched between the heated rollers and passed between the pressure rollers so that the film is fused and the film is coated on the surface of the container.

As such, the elements commonly needed in the existing laminator and document shredder require a drive source and a connection means for transmitting power of the drive source. Therefore, a single drive source (motor) is sufficient to press the laminator's press roller and the disc type blade of the shredder. It can be used as a driving source to drive.

However, the power generated by the drive motor must be connected to the press roller for the laminator function, and when the document shredder is used, the power must be connected to the disk-type blade of the document shredder to selectively connect or disconnect the power. Power switching means are required.

As described above, the laminator having the sedan function according to the present invention is configured to selectively use the power of the sedan function or the laminator function using a single drive source.

Hereinafter, with reference to the accompanying drawings for a laminator having a sedan function according to the present invention in more detail as follows.

Referring to Figure 1, Figure 1 shows a first embodiment of a laminator having a document shredding function according to the present invention, in the drawing, reference numeral 10 is a pressure roller for the laminator, 20 is a disc-shaped blade for the shredder, 30 is a drive motor, 40 is a power switching device for selectively connecting the power of the drive motor 30 to the pressure roller 10 and the disk-type blade (20).

The pressure roller 10 has both ends supported by the bracket 11 so as to be rotatably supported, and one shaft end thereof is connected to the power of the driving motor 30 to rotate. ) Is attached, and two pressure rollers 10 positioned up and down on the opposite shaft end are engaged with each other through the spur gear.

The disc-shaped blade 20 for the shredder is rotatably received on the support 21 extending from the bottom surface of the case to a predetermined height on the left and right sides, and at one end of the shaft, the drive motor 30 The driven gear 22 to be connected to the power is connected.

The power switching device is an element for connecting or disconnecting power to the blade described above. Therefore, the knob 41a of the switching lever 41 slightly protrudes out of the outer case of the laminator, and rotates to the bracket 11. It is possibly supported by a pivot shaft, and has a first planetary gear 43 and a second planetary gear 44 on its surface. According to the switching position of the switching lever, the first planetary gear 43 and the sun gear 32 and the second planetary gear 44 mesh with the driven gear 22 attached to the shaft of the disc-shaped blade 20, respectively. Or spaced apart. In addition, a stopper fixing groove 13 is provided on the bracket 11 so that the position of the switching lever 40 is not deformed, and the switching lever includes a stopper 42 inserted into the stopper fixing groove 13. .

Although not shown in the drawing, the operation of the driving motor 30 is performed by the main power switch, and when the power is applied, the heating roller is heated while the pressure roller is heated to a high temperature.

Therefore, the pressure roller 10 is rotated through the planetary gear meshed with the sun gear 32 which is rotated by the worm gear 31 of the driving motor, and the paper is coated with the film and discharged. When the original drive is discharged from the drive motor 30, the main power switch is turned off to cut off the power to stop the drive motor 30 to stop the pressure roller.

Reference numeral 34 is a planetary gear for adjusting the rotational speed between the sun gear 32 and the pressure roller 10 side spur gear 12 is rotatably coupled to the bracket (11).

The configuration according to the sedan function is implemented as a switching lever 41, the switching lever 41 is pivotally coupled on the bracket 11, the other end is two stopper fixing groove on the bracket (11) The stopper 42 moves from one side to the other side so that the position is fixed while the position is switched.

At this time, the stopper 42 inserted into the stopper fixing groove 13 has a relatively narrow diameter between the fixing grooves symmetrically formed so that the stopper 42 passing through the place is caught on the inner surface of the stopper 42 when it moves. In the case of moving to the other side of the fixing groove, the stopper 42 does not move and remains in a locked state until the knob 41a of the switching lever 41 protruding out of the case is changed to the original position slightly.

Accordingly, the knob 41a of the switching lever 41 is positioned to protrude slightly out of the case of the laminator, and if the knob 41a is shifted in the front and rear directions, it is rotatably coupled to the lever 41. As the first planetary gear 43 and the second planetary gear 44 rotate integrally, the first planetary gear 43 is the sun gear 32 and the second planetary gear 44 are the shafts of the disc-shaped blade 20. Meshed with the driven gears 22 attached thereto.

Accordingly, the power of the drive motor 30 is transferred to the sun gear 32, the first planetary gear 43, the second planetary gear 44, and the driven gear 22 in the document cutting operation. The document is cut by the blade 20.

This action stops the driving motor by turning off the main power switch while all the grippers inserted into the grip insertion restraint are pulled out.

In addition, in order to release the switching lever 41 in the sedan mode, when the switching lever 41 is moved to its original position, the lever 41 is rotated around the pivot shaft 45. In this case, the stopper 42 is described above. ) Is moved to the opposite stopper fixing groove (13). Of course, the first planetary gear 43 and the second planetary gear 44 are separated from the sun gear 32 and the driven gear 22, respectively, and the power is cut off.

4 and 5 show a second embodiment of the laminator with a document shredder according to the present invention, the second embodiment is a pressurizing roller 10 for laminating the power without using the switching lever 41 and By driving the disc-shaped blade 20 for the sedan at the same time shows an example of the purpose of the present invention.

As can be seen in the figure, the sun gear generated from each of the sprockets 12a and 22a and the driving motor 30 attached to the pressure roller 10 and the disk-shaped blade 20 through the chain C. By connecting the chain (C) between the 32 can be configured to perform the laminator function and the sedan function at the same time when the drive motor 30 rotates. Of course, the chain (C) is not only a medium for connecting the power, it is also possible to employ a variety of power transmission means such as a variety of known power connection means, for example, a gear belt consisting of a timing belt or a spur gear.

As described above, the present invention integrates the sedan function with the laminator to reduce the manufacturing cost and provides the advantage of easy use and reduced installation space by the integrated function.
