Изобретение относитс к упаковочной технике и предназначено дл сварки и отделени один от другого пакетов, изготовл емых из термосваривае.мого материала.The invention relates to a packaging technique and is intended for welding and separating packages made of heat-sealing material from a material from one another.

Одним из требований, предъ вл емым к устройствам, производ щим сварку и отделение пакетов с жидким продуктом вл етс надежное вытеснение продукта из зоны образовани поперечного шва. Дл этого известные устройства дл сварки и отделени пакетов, содержапдие пару прижимных губок (в корпусах которых размещены нагревательные элементы) и лезвие дл отрезани пакета, снабжено вытеснител ми продукта из зоны сварки, расположенными в несколько р дов. Эти вытеснители при работе устройства постепенно вытесн ют жидкость через трубу в зону рукава, наход щуюс над пакетом 1.One of the requirements for devices that produce welding and separating packages with a liquid product is to reliably displace the product from the transverse weld zone. For this, the known devices for welding and separating the packages, containing a pair of clamping jaws (in the cases of which heating elements are placed) and a blade for cutting the package, are equipped with product displacers from the welding zone arranged in several rows. These displacers, when the device is operated, gradually displace the liquid through the pipe into the area of the sleeve above package 1.

Конструкци известных устройств сложна , в его состав входит приводной механизм вытеснителей и самосто тельный привод трубы, через которую вытесн етс продукт. К тому же сварные щвы, образуемые известным и устройствами, ненадежны .The design of the known devices is complex; it includes the drive mechanism of the displacers and the independent drive of the pipe through which the product is forced out. In addition, the welded grooves formed by the known and devices are unreliable.

Цель устройства - повышение качества сварных швов при упрощении конструкции .The purpose of the device is to improve the quality of welds while simplifying the design.

Дл этого в предлагаемом устройстве, содержащем пару прижимных губок с нагревательными элементами, размещенными в корпусах этих губок, лезвие дл отрезани пакета и вытеснитель продукта, последний расположен в корпусе одной из губок и выполнен в виде подпружиненного ползуна с каналом дл прохода лезви .For this, in the proposed device comprising a pair of clamping jaws with heating elements placed in the bodies of these jaws, a blade for cutting the bag and a product propellant, the latter is located in the body of one of the jaws and is designed as a spring-loaded slider with a passage for the blade to pass.

На фиг. 1 схематично изображено предлагаемое устройство в момент начала перехвата рукава и постепенного выжимани продукта из зоны сварки, поперечный разрез; на фиг. 2 - то же, сечение А-А на фиг. 1; на фиг. 3 - то же, в момент сварки пакетов и их отделени .FIG. 1 shows schematically the proposed device at the moment of the beginning of the interception of the sleeve and the gradual squeezing of the product from the weld zone, a cross section; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 - the same, at the time of welding packages and their separation.

Устройство дл сварки и отделени пакетов к упаковочным машинам содержит пару прижимных губок в корпусах 1 и 2, вытеснительвыполненный в видеA device for welding and separating packages to packaging machines contains a pair of clamping jaws in housings 1 and 2, the displacer executed in the form

Claims

20, slider 3, and blade 4. In the sponge body 1, a notch 5 is made, on both sides of which dielectric strips 6 and 7 are located, against the latter strips of heating elements 8 and 9 s. the projections 10. In the housing 2 of the other jaw there is a notch 11, in which the slider 3 is mounted with a channel 12 through which the blade 4 passes attached to the case 2. Elastic pads 13, 14 are also on both sides of the notch 11 Slider 3 installed in cutout 11, is equipped with springs 15. The device operates as follows. Sponges with shells 1 and 2 are closed and squeeze the opposite walls 16, 17 of the sleeve of the packaging film. At the beginning of the approaching of the sleeve walls, the slider 3 acts, and the product is squeezed out of the zone of convergence of the sleeve walls. After pressing the walls 16, 17 sleeves slider 3 to the housing 1 is the convergence of the buildings 1 and

2. As a result of this, squeezing the spring 15, the blade 4 protrudes and cuts the bag off the sleeve. With the full approach of the buildings 1, 2, the walls 16, 17 are finally welded and the transverse seam is formed. Then sponge with shells 1, 2. the knife is removed from channel 5, and then the slider is reset

3. The proposed device provides packages with high-quality welds. Apparatus of the Invention A device for welding and separating packages for packaging machines, comprising a pair of clamping jaws, in the body of which heating elements and a blade for cutting the package are placed, and a product displacer from the welding zone, characterized in that, with a view to improving the quality of the weld, the displacer is located in the body of one of the jaws and made in the form of a spring-loaded slide with a channel for the passage of the blade.
