Description

PAPERBOARD WRAPPING DEVICE

BACKGROUND OF THE INVENTION The invention relates to paper tape winding devices and may be used in the automation and computing industries, such as cash registers, desk calculators with printers, data recorders, cashless check systems for personal paper, or other machines for processing information and printing. on a recording tape.

There is a known paper tape winder described in the German Datamega Magazine, July 1993, pages 13 and 25. and includes a built-in paper tape drive electric motor and a special winding cassette that can be extended and disassembled horizontally. It can be autonomous or built into the DAF-200.

The disadvantage of this known device is that it requires two separate drives - one for the printer and the other for wrapping paper tape.

Also known is a printer paper tape winding device according to European Patent Application No. 89311246.6, SIK B 41 J 15/06, which comprises a winding shoulder having a paper roll on one end and a wound axis rotatably mounted in a housing. The winding shoulder has one end of the winding reel and the other end of the shoulder is attached to the housing. The machine is driven by a printer motor with a belt drive, which drives the roll of paper.

The disadvantage of the known device is that it has a complicated construction, but the winding of the paper tape is implemented by a special drive mechanism.

Of all known devices, the closest device to the one described in the present invention is an office equipment paper tape winding device, selected as a prototype, under former GDR Patent No. 5,198. 241968, SIK G 06 K 13/26, comprising a winding reel mounted on a winding reel, a friction roller axis on which a friction roller is mounted, a roll of reel paper tape fixed on a rolling support, the winding reel rolling support and a friction roller the axles are mounted in the first frame, and the rolling support of the roll of reel tape is in the second frame. The frames are movably fixed by means of a screw, the moving parts of the frames are interconnected by a spring. The friction roller shaft with gears is clutched by a winding roller driven roller bearing for transmission of torque movement, wherein the friction roller rotation speed is equal to or less than the winding roller roller rotation speed.

The drawback of the known device is its intricate design.

the object of the present invention is to simplify the construction of a paper tape winding device.

The object of the present invention is achieved by placing the roll paper reel on and / or in contact with the surface of the paper roll in a paper belt winder comprising a frame with roll and roll paper roll reels supported thereon and a printer drive shaft for transporting paper roll.

The object is also achieved by the horizontal reels of the roll and roll paper rolls being arranged horizontally on the roll supports which are arranged in the frame according to the coil segments, wherein at least the first roll support of the roll reel is located between the roll roll and the roll paper.

The stated aim is also achieved in that the reels of the roll and roll paper webs, with the roll supports, are arranged on top of each other in a guide so that they have freedom of movement in the vertical direction.

The objective is also achieved by placing a friction roller with freedom of movement in the vertical direction between the reels of the roll and roll paper web.

The drawings accompanying the description of the invention show examples of the implementation of the device:

FIG. 1 - a paper tape winding device with a horizontal arrangement of paper tape reels,

FIG. 2 - a paper tape winding device with a vertical arrangement of paper tape reels,

FIG. 3 - a paper tape winding device with a vertical arrangement of paper tape reels in section,

FIG. 4 - Friction roller arrangement between vertically spaced rolls of paper tape.

The paper tape winding device according to FIG. 1 comprises a frame 1 with horizontally arranged rolls of reelable and rollable paper tape 2, 3 with paper tape 4, which are arranged in segmented pockets a and b. The segmented pockets a and b are formed by rolling supports 6, which are arranged in frame 1 according to the outer circumference of the coils 2, 3. The paper web 4 of the reeling coil 2 encircles at least the first rolling support 6 and may be further spaced between the surfaces of the reeling and winding reels 2, 3 and the other rolling supports 6 with an entrance to the printer's paper perception slot. The paper tape inserted into the printer paper capture slot 4 surrounds the printer drive shaft 5 and is connected through the printer paper output slot to the roll paper tape reel 3 that fits in its segmented pocket

b. In the center of the wrapping paper reel 3, a weight compensation roller 7 may be disposed. If a coil carrier sleeve 8 is used to wind the paper web reel 3, the winding end of the paper tape 4 is secured to the carrier sleeve with glue or adhesive tape.

The paper tape winding device according to FIG. 2 and FIG. 3 comprises a frame 1 having vertical and guide rolls 2, 3 placed on top of one another in the central roller supports 6, the surfaces of the paper webs being in continuous frictional contact with one another. From a service point of view, it is expedient to position the roll paper roll reel 3 above the roll paper roll reel 2, with the roll paper roll reel 3 formed with the cheeks 10 and its rolling support to be folded out and disassembled horizontally. The roll paper web 4 from the roll paper roll 2 wraps around the printer drive spindle 5 through the printer paper catch slot and is connected to the roll paper roll reel 3 through the printer paper output slot. If a friction roller 11 is disposed between the roll paper roll and roll rolls 2, 3. 4, it is located in the vertical guides 9 and can move freely in the vertical direction by being in constant frictional contact with the paper roll surfaces of both coils.

The devices described above work as follows.

At horizontal positioning of the winding and winding reels 2, 3, the paper web 4 is moved by the drive motor 5 of the printer motor. Due to the fact that the paper tape of the reel 2 wraps at least the first rolling support 6, the reel 2 of the paper reel is always oriented in its segmented pocket a, regardless of the length / quantity of the remaining paper tape. When moving the paper tape 4, the portion of the paper tape 4 that is ejected from the printer's paper output slot is simultaneously wound onto the rewinding paper reel 3. This is achieved by having the reeling paper reel 3 in constant frictional contact with the reeling portion of the paper web 4 which is moved by the printer motor shaft 5. The permanent frictional contact is provided by the weight of the reel 3 or by a weight compensating roller 7. the direction of rotation / rotation coincides, thus providing the unit winding / winding process for the paper tape 4 one-sided, that is, the same side of the paper tape is wound and wound. By placing the roll paper web 4 under the roller supports 6, a roller path rotating in the opposite direction to the winding reel 3 can be created.

At the vertical arrangement of the reeling and winding reels 2, 3, the paper web 4 is reeled from the paper web winding reel 2 by the drive motor 5 of the printer. The paper roll 4 is wound through a printer and is wound onto a paper roll reel 3 which, under its weight, is in continuous frictional contact with the paper surface of the roll paper roll 2. Continuous frictional contact is achieved by allowing the paper web coil 3 to move freely in the vertical direction of the guide 9 of the frame 1 (the selection of the lever type guide is not excluded), thereby compensating for changes in the thickness of the coils 2,3. In this case, the direction of rotation / rotation of the paper web winding and winding reels 2, 3 is reversed and the paper web 4 reverses its winding side. If it is necessary to carry out a one-sided reeling / winding process of the paper tape 4, this is achieved by rotating a friction roller 11 between the coil surfaces, which changes the direction of rotation / rotation of the paper tape reel 3.

The proposed paper tape winding devices are simpler in design and do not require constructive intervention in the drive system. The paper tape winding drive itself uses the roll paper itself, which is moved by the printer's drive shaft. The device can be constructively designed either as a built-in variant or as a stand-alone, replaceable unit with the ability to be customized for different printer configurations. The wrapped paper tape reel (check tape) is easy to store.
