Description

 The invention relates to the packaging of products and is intended for packaging in an annular parcel from hot-melt adhesive tape of cash tickets of all virtues, new and used.

 Known automatic banding machine COM JD (series J-240).

 The known machine comprises a housing, tape drive, loop forming and welding mechanisms with drives and a knife for cutting the tape.

 The tape drive mechanism is made up of two pairs of rollers, one of which stretches the tape in one direction and the other in the other. The movement of the rollers is controlled using a cam-lever mechanism.

 The loop-forming mechanism is a table, a time of clamps and a grip. One of the clamps is made in the form of a lever, fortified with the possibility of angular movement.

 In the process, the tape is stretched between two clamps, fixed by a grip, unfolds and leads to the table. At the same time, a pair of rollers feed the tape to form a loop. The mechanism is controlled by a cam-lever mechanism.

 The welding mechanism is made in the form of a lever with a welding head, on which a knife for cutting the tape is mounted.

 The disadvantages of the above machine should include its low performance, structural complexity, as well as large dimensions.

 Closest to the claimed is the well-known "Device for banding the roots of securities", patent of the Russian Federation N 2123462, M. Kl. 65 B 27/08, declared July 28, 1997, publ. 12/20/1998.

 This device comprises: a housing, a tape drive mechanism with a roll holder, a feed channel and a sensor for determining the length of the tape and a loop forming unit. The device also contains a welding mechanism with a welding head, a knife for cutting the tape, drive mechanisms and a control unit.

 The loop-forming mechanism has a table for accommodating the spine, which is mounted with the possibility of rotation about a horizontal axis. The table includes a shaft, a spring-loaded clamping lever and a gear. A knife is mounted on the clamping lever for cutting the tape. The rotary table serves to clamp the end of the tape with a spring-loaded lever and rotate it when a loop is formed. The bottom surface of the table is designed to form a weld.

 The welding mechanism has a welding head, the movement of which is carried out by means of a cam mechanism.

 The loop forming and welding mechanisms have a common drive, the cams of each of the mechanisms and a program disk connected to the control unit are mounted on its shaft.

 The disadvantages of this design include the relatively low productivity of the device due to the complex process of looping, consisting of several stages, preliminary and final, as well as the need for accurate positioning of individual nodes and elements of the device.

The processes of feeding the tape and looping in a known device are as follows:
- in preparation of the table clamp;
- in the exact fixed feed of the tape;
- in turning the table and clamping the tape;
- in the formation of a small loop;
- in the rotation of the table with a spine;
- in the formation of a large loop.

 Thus, the device has a complex loop formation algorithm, which leads to a decrease in its reliability in operation, and also leads to an increase in its dimensions.

The tasks that the authors set themselves when creating the invention include:
- increasing the productivity of the device by simplifying the loop-forming unit and reducing the time required for the formation of the loop.

Along the solved tasks are:
- improving the reliability of the device in operation and ease of operation;
- reducing the size of the device.

 The tasks are achieved due to the fact that in the device containing the housing, a tape drive with a roll holder, a feed channel and a sensor with an obturator disk for determining the length of the tape, a loop-forming unit with a table, a welding mechanism with a welding head, a knife for cutting the tape and drive mechanisms, the loop-forming unit is made in the form of a channel, bounded by the walls, in the form of a loop, inside of which a little table for the root is cantilevered. The roll holder is made in the form of a tray and is placed in the upper part of the body above the channel, and the welding mechanism is equipped with a mechanical transmission for reciprocating movement and placed in the body directly under the table of the loop-forming unit. At the same time, welding and tape drives have individual drives interconnected by a control unit.

 Moreover, the welding mechanism is equipped with a software bar and a linear motion control sensor associated with the control unit.

 In addition, the welding mechanism is equipped with a pair of clamps for the tape and a knife for cutting it.

 The drive of the tape drive is made reversible.

 The principle of operation of the device is illustrated by drawings: in FIG. 1 schematically shows the device as a whole; in FIG. 2 shows its tape drive mechanism; in FIG. 3 shows a loop-forming unit of the device; in FIG. 4 is an image of a welding and cutting mechanism.

 A device for banding the roots of cash tickets comprises a housing 1, a tape drive 2, a loop forming unit 3, a welding mechanism 4.

 The tape drive mechanism 2 includes a roll holder 5, which is made in the form of a tray and placed in the upper part of the housing, a roller unit placed in an individual housing 6, and including a receiving roller 7 and a drive 8, as well as a pressure roller 9, spring-loaded with a spring 10. Tape drive mechanism 2 also includes a supply channel 11, obturator disk 12, mounted on the shaft of the pressure roller, and a sensor 13 for determining the length of the tape. The drive roller 8 of the tape drive mechanism 2 has an individual drive (not shown in the drawing), it is driven by a DC motor and a pair of belt drives, which allows you to move the tape in two directions.

 The loop-forming unit 3 is made in the form of a channel 14, bounded by the walls, having the shape of a loop, inside of which a table 15 for the spine is cantilevered. Channel 14 is located in the middle of the housing, under the roll holder 5.

 The welding mechanism 4 is placed in the housing 1 directly under the table 15 of the loop forming unit 3 and comprises a housing 16, a spring 18 welding head 18, inside which the heating element 19 and the temperature sensor 20 are located. The welding mechanism 4 is also equipped with a knife 21 for cutting the tape, spring loaded in two directions by springs 22 and 23, and a pair of clamps 24 and 25. The left clamp 24 has a groove 26 and is spring-loaded with a spring 27. The right clamp 25 with spring 28 has a protective rod 29. The welding mechanism 4 is equipped with a mechanical front whose 30 for reciprocating movement. The mechanical transmission 30 consists of a screw 31 connected to the housing 16 of the welding mechanism 4, and a drive pulley - nut 32, which is located between the angular contact bearing 33 and the support bracket 34.

 The tape drive 2 and welding 4 mechanisms are interconnected by a control unit (not shown) that synchronizes their work.

 On the housing 16 of the welding mechanism 4, a program bar 35 is coupled, interacting with the sensor 36 of the linear movement of the mechanism.

 The mechanical transmission 30 of the welding mechanism has an individual drive from a DC motor and a belt drive (not shown in the drawing) for moving the mechanism in two directions.

 The device operates as follows.

 Before bandaging the cash ticket spine, the roll with the tape is installed in the roll holder 5. Through the take-up roller 7, the tape is inserted into the feed channel 11 until it touches the rollers 8 and 9. When the drive of the tape drive 2 is turned on in the “refueling” mode, the started rollers 8 and 9 capture the end tape and advance it through channel 11 to the length specified by the control unit. The counting of the length of the tape is carried out by means of an obturator disk 12 mounted on the shaft of the pinch roller 9 and a sensor 13 for determining the length of the tape.

 When placing the root in the banding zone, the control unit includes tape drives 2 and welding 4 mechanisms. The first using the rollers 8 and 9 feeds the tape forward, and the second by means of a mechanical transmission 30 begins to move "up". The tape using the tape drive mechanism 2 enters the tape slot 26 of the left clamp 24, slides along the upper surface of the protective rod 29 of the right clamp 25, and then enters the channel 14 of the loop forming unit 3. There, the tape, pressing against the inner surface of the channel 14, is fed into the gap between left clamp 24 and table 15 to the right edge of the latter. When the end of the tape goes under the table 15, the left clamp 24 presses it on the bottom surface of the table 15. At this point, the drive of the tape drive 2 is turned on in the opposite direction, and the loop tightens the spine located on the table 15. The welding mechanism 4, continuing to move up, pushes with its right clip 25, the stretched part of the loop to the lower surface of the table 15. The knife 21, pressed to the plane of the left clamp 24, slides along it and cuts the stretched part of the loop. The left end of the tape pullers 8 and 9 is pulled back and stops after a signal from the sensor 13 determine the length of the tape to the control unit. The right end of the tape is pressed against the lower surface of the table 15 with a heated welding head 18, and welding occurs. The welding process ends after a command is received from the control unit, which, after a certain time, turns on the drive of the welding mechanism 4 in the opposite direction, and that mechanism is retracted down to its original position.

 The bandaged root is removed from the table 15. Then the cycle is repeated, and the whole process is carried out automatically.
