Description

The invention relates to a technique of packaging, and in particular to methods of packaging the end portions of long products into moisture-proof packaging material without changing the position of the products to be packaged.

The purpose of the invention is to increase productivity and expand technological capabilities.

The method of packing the end parts of long products involves forming a half-sleeve by folding the packaging material web twice in its length, which is produced from the initial in the direction of movement of the web section, and sealing the end, forming a number of products, feeding it, placing the end parts of the product in the semi-sleeve and separating packages, and the placement of con-. The primary parts of the products in the semi-sleeve are filled with the first product in a row, placed at the sealed end, and the placement of the end parts of the subsequent products of the series is combined with its supply, making it in a direction parallel to the longitudinal axis of the packaging material web, with the gripping of the fabric, envelope end parts of products. „

FIG. Figure 1 shows a schematic view of the device for packaging the end portions of long products, side view; pa fpg. 2 the same, top view.

The device comprises a roll holder 1 of a packaging material, for example, a plastic film 2, and a welding-cutting device, including welding beams 3. The products are indicated by the position 4.

The proposed method is interpreted as follows.

Places in it welding beams. From the poly-technological parameters proposed

dimensional film 2 forms a half-sleeve, a method (film width, packing film 2 along the length of the batch of parts, etc.) to cut the length, and seal the front end of the film 2 in the direction-liver of normal operability by dumping the film reliable

 and high-quality seam, it is necessary to ensure the end parts of the first in the direction of maintaining the tapering layers

the supply of the product 4 is placed at the sealed-Yu film 2 outside, reducing the angle of the end of the semi-sleeve. Thus, dressing the layers before the welding position.

Further, the product 4 is stopped due to the relative position of the sealing portion and the connection of the layers of the half sleeve to the film and the front weld using a pile-sleeve extended by the product. but

The approaching layers of the web of packing roll washers, for sealing the package material occurs by virtue of the initial drive linear welding joint of these layers with a pre-35 le traverse with the heating element sealing the front with the stakes and the knife between them, folded semi-manual-when technological need to pack. Already when this operation is performed, the other end of the long frame of the film 2 is brought together and joined. If the process can be carried out, the distance between the edges of the film 2 at a time and on the other side of the products becomes variable along the distance from the proposed method. If necessary, getting more than the width of the web, down to zero. Plant flush packaging is possible to use, this shedding of tapering edges is the first of the heat-shrinking film, followed by heat 4, up to the stop from the inside in the front processing of the packaged end of the half sleeve and moving the first light of 45, for example, in the heat-shrinkable heater 4 to the side from the roll captive tunnel.

The convergence of the layers of the film 2 at the same time about the packaging of the end parts of long

it develops spontaneously. The product allows one to achieve an increase in production, however, the value of the angle of approaching more than 4 times. This (layer) film 2 affects the quality and 50 is achieved by combining operational-package reliability. In the zone of formation and execution of them along the moving welded groove, this angle should be the sight of the products. Such operative conditions are excluded, so that under the action of convergence, such as pre-storing after welding beams, 3 layers of a 2-layer film of packaging material in half-wrinkle and do not warp. If shi-kav, sealing its front end, the wrap of the film web 2 is relatively non-expanding the opening angle, putting on the polka, and the distance from the roll to the position of the film on the ends of the products, welding elongation is sufficient; Slack Packing. The cycle time of the layers of the film 2 is formed is determined only by the time of two operations - the supply of the product (film) to the sealing position and the formation of the weld.

In addition, when packaging is formed directly around the product, the quality of the packaging is improved, since bends and contact material of the packaging material are excluded.
