Изобретение относитс к оЬорудованию дл упаковки штучных изделий и может найти применение в шинной промьоишенности , в частности при упаковке пневматических шин.The invention relates to the packaging of piece goods and may find application in tire industry, in particular when packaging pneumatic tires.

В основном авт. св. № 585103 описано устройство дл упаковки штучных изделий ленточным материалом, содержащее ротор с установленной на валу Q катушкой дл ленточного материала и тормозное приспособление, состо щее из дугообразной планки и диска, смонтированного на валу катушки.Basically auth. St. No. 585103 describes a device for packing piece goods with a tape material, comprising a rotor with a coil for a tape material mounted on a shaft Q and a braking device consisting of an arcuate bar and a disk mounted on a coil shaft.

Недостатком этого устройства 15 вл етс отсутствие посто нного нат жени упаковочной ленты. Из-за этого она провисает, рветс , и изделие упаковываетс некачественно.A disadvantage of this device 15 is the lack of constant tensioning of the packaging tape. Because of this, it sags, tears, and the product is packaged poorly.

Целью изобретени вл етс создание посто нного нат жени упаковочной ленты при упаковке издели .The aim of the invention is to create a constant tension on the packaging tape when packing the product.

Это достигаетс тем, что на роторе параллельно валу катушки закреп- 25 лена ось с двуплечим рычагом, одно плечо которого изогнуто по дуге, соответствующей кромке диска, и имеет ролик дл взаимодействи с дугообразной планкой, а на другом плече зоThis is achieved by the fact that on the rotor, parallel to the shaft of the coil, there is fixed an axis with a double-arm lever, one shoulder of which is bent along an arc corresponding to the edge of the disk, and has a roller for interacting with the arcuate bar.

На фиг. 1 схематически изображено описываемое устройство на фиг.2 катушка в начальный момент взаимодействи с планкой; на фиг. 3 - сечение А-А на фиг. 2; на фиг. 4 - сечение В-Б на фиг. 2.FIG. Figure 1 shows schematically the device described in Figure 2; the coil is at the initial moment of interaction with the bar; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section B-B in FIG. 2

Устройство дл упаковки штучных изделий ленточным материалом содержит ротор 1 с установленной на нем катушкой 2 дл ленточного материала 3 и тормозную дугообразную планку. 4. .Катушка имеет тормозной диск 5, контактна поверхность которого покрыта фрикционным материалом 6 (например , обрезинена).The apparatus for packaging piece goods with tape material comprises a rotor 1 with a coil 2 mounted thereon for the tape material 3 and a brake arcuate bar. 4. The coil has a brake disc 5, the contact surface of which is covered with friction material 6 (e.g. rubber coated).

Claims

20 parallel to the shaft of the coil 2 is mounted brake lever 9, fastened at one end with the housing by spring 10. Brake lever 9 is equipped with a support roller 11 mounted in the plug 12 on the axis 13 and has an arcuate section. At the end of the disk 5 a washer 14 of friction material is fixed on which a coil 2 with a packing tape is installed. The device works as follows. The packing material 3 from the coil 2 is applied to the product 15. When the rotor 1 rotates in the direction of arrow B, the coil moves away from the product, rotates around its axis in the direction of arrow G and unwinds the packing tape with a constant tension. In the area, the brake disc 5 is braked due to pressing the arcuate section of the lever 9 to the edge of the disk 5 by the spring 10. In this area, due to the action of friction forces between the surfaces of the brake disk 5, washers 14 and coil 2, a braking torque is created on the shaft . It is less than the belt tension force, so that the packing material 3 is applied to the product 15 with a constant tension, preventing the coil from unwinding the packing tape more than is necessary to apply it to the product. In section 05-04-0, the support roller 11 mounted in the fork 12, free rotates on the axis 13, contacts the brake bar 4, depressing the lever 9 from the disk 5 of the coil 2, and the disk interacts with the brake bar, allowing coil 2 Choose a packing tape with a constant tension due to the fact that the moment of the tension force is less than the moment of the friction forces. As soon as the torque from the tension force in the packaging material 3 exceeds the moment of frictional forces, coil 2 again begins to slip relative to the brake disk 5 in the direction of arrow G, unwinding the tape with constant tension. Thus, in the process of packing, the packing tape is superimposed around the entire perimeter of products with constant tension without sagging, which improves the quality of the packaging and eliminates breakage of the tape. Claims of the invention The device for packing piece goods with tape material according to the author. St. No. 585103, characterized in that, in order to ensure constant tension of the tape material, an axle with a double-arm lever is fixed on the rotor parallel to the coil shaft; On the other arm of the lever there is a spring fixed on the rotor.
