Description

The invention relates to the production of radio electronic elements, namely, devices for cutting tape material in the manufacture of coiled capacitors.

The aim of the invention is to improve the operational capabilities by facilitating and unloading reels and sleeves with tape material.

FIG. 1 shows a kinematic diagram of a device for cutting tape material; in fig. 2 - the device, top view; in fig. 3 shows the node I in FIG. 2; in fig. 4 - sleeve fixation structure; in fig. 5 - arm fastening structures with sleeves; in fig. 6 — spindle for reel with tape material.

The device consists of a straightening shaft 1 mounted rotatably from the electric motor 2, with sleeves 3 mounted so as to cooperate with the straightening shaft 1. The sleeves 3 are mounted on the rotary levers 4 and are arranged around the circumference of the straightening shaft 1 rows. A reel 5 with a tape 6 is mounted on a spindle (axis) rotatably under the action of tensioning the tape 6 during rewinding. The straightening roller 1 is clamped to the expanding shaft 1 by means of a spring-loaded pressure roller 7. The device is equipped with a tension roller 8. The tension roller is installed between the reel 5 and the pressure roller 7. The fixed blades 9 are offset from each other by the width of the cut ribbons (about 2 mm), their number is, respectively, one less than the number of ribbons cut, and they are installed between the tension 8 and the pressure 7 rollers. The spreading device is formed by the sector of the expansion shaft 1 located between the pressure roller 7 and the corresponding row of sleeves 3. Thus, the spreading devices on the one hand are as much as the rows of sleeves 3, on the other hand the straightening device 1) The Spread Shaft performs the function of driving the sleeves at a constant linear winding speed (not dependent on the increase in the winding process of the sleeves' radius), i.e. is also a winding roller.

The rows of sleeves 3 (Fig. 2) are displaced relative to each other along the axis of the winding shaft 1 by an amount b, and the sleeves of each row are displaced relative to each other along the same axis by an amount (n -1) b, where b is the width of the cut ribbon , n - number of rows of sleeves,

Each row of sleeves is provided with an axle 10, on which pivot levers 4 are mounted by means of a hinge 11.

Each lever 4 is provided with an additional arm 12, on which a counterweight 13 is placed, which serves to press the sleeve 3 against the winding shaft. In order to avoid distortions, the levers 4 are installed with the possibility of rotation in the guides 14.

The tension in the device is created by braking the reel 5. The tension roller 8 is designed to guide the belt 6. Its position is strictly defined in space and is interconnected with the position of the knives.

FIG. 3 shows the design of the sleeve 3 (in section). The sleeve 3 (each of the sleeves) consists of a screw 15 fixed on the pivot arm 4 using a screw 15 and a font

0 16 axis 17 with flange. An axis 18 is fitted with a disk 18 with a ring 19. Axial movement of the disk 18 is held on one side by the surface of the lever 4, and on the other by the flange of the axis 17. To do this, as far as possible from the axis of the disk 18, annular projections 20 are made on it the purpose of which is to prevent displacement and skew of the disk 18, as well as to reduce the sliding friction, all device nodes are installed on the frame 21.

A device for cutting tape material works as follows.

The reel 5 with the tape 6 to be cut is mounted on an axis and

5 is braked to create a subsequent tension. The braking may be effected, for example, using a brake roller or by any other known method. Tape b when refueling

0 bends the tension roller 8 and is cut by the knives 9 into strips of the required width, which are pressed by the pressure roller 7 to the surface of the straightening shaft 1. The cut and straightened tapes bend around

5, the corresponding sector of the straightening shaft and fastened to the rings 19 of the respective sleeves. The rotation of the straightening shaft 1 is transmitted from the electric motor 2. From the straightening shaft 1, the rotation is re0, which is in contact with the counterweight 13 of the sleeves 3, onto which the cut tapes are wound. Thus, the spreader shaft 1 serves both to drive the sleeves 3 and

5 straightening device.

As you cut and wind, the diameter of the sleeves 3 increases, the levers 4 rotate on the hinges 11 around the axes 10, while the sleeves 3 remain pressed against the rotating unwind shaft 1 due to

counterweights 13, placed on the additional arms of 12 levers 4.

At the end of the cutting and rewinding, a new reel 5 with tape material is installed, rings 19 with cut tapes wound on them are removed, new rings 19 are installed, the tape B is loaded, as indicated above, and the installation is ready for operation again
