Изобретение относитс  к устройствам дл  закупоривани  сосудов эластичной пленкой.This invention relates to a device for sealing vessels with an elastic film.

V Известно устройство дл  укупорки сосудов , состо щее из укрепленной с возможностью вертикального перемещени  прижимной плить, концентрично смонтированных относительно последней приспособлени  дл  подгибани  кра  пленки и нагревани  его и ножа, расположенного под прижимной плитой, приспособлени  дл  нат жени  пленки и стола дл  сосудов 1. Оно  вл етс  наиболее близким к изобретению по технической сущности и достигаемому результату. Однако устройство не обеспечивает достаточной герметичности и высокого качества укупорки сосуда.V A device for sealing vessels is known, consisting of a clamping plate strengthened with the possibility of vertical movement, concentrically mounted relative to the last device for bending the edge of the film and heating it and the knife located under the pressure plate, the device for tensioning the film and the table for vessels 1. It is closest to the invention by its technical essence and the achieved result. However, the device does not provide sufficient tightness and high-quality vessel capping.

Целью изобретени   вл етс  повышение герметичности и качества укупорки. В описываемом устройстве это достигаетс  тем, что в нем В прижимной плите образованы каналы дл  подачи холодной воды, нож смонтирован на внешней стороне приспособлени  дл  подгибани  кра  пленки и нагревани  его, а последнее имеет полость, сообщенную с источником сжатого воздуха. Кроме того, устройство может быть снабжено нагревательным элементом, установленным в полости приспособлени  дл  подгибани  кра  пленки и  агревани  его, а поверхность прижимной плиты выполнена вогнутой.

Устройство содержит прижимную плиту 1, приспособление 2 дл  подгибани  кра  3 пленки 4 и нагревани  его, нож 5 дл  обрезани  пленки, приспособление б дл  нат жени  пленки и стол 7 дл  сосудов 8 с фиксатором 9 дл  последних. Все части устройства смонтированы на раме 10. Приспособление 2 дл  подгибани  кра  пленки и нагревани  его смонтировано концентрично прижимной плите 1 и имеет полость 11, сообщающуюс  через форсунку 12 с источником сжатого воздуха (на чертеже не показан). Нож 5 дл  обрезани  кра  пленки расположен на приспособлении 2 дл  подгибани  кра  пленки и нагре вани  его, а на ноже установлен нагревательный элемент 13, например, импульсного типа. Прижимна  плита 1 укреплена на штоке силового цилиндра 14 с возможностью вертикального перемещени , при этом в прижимной плите образованы каналы 15 дл  подачи холодной воды и подобной ей жидкости. В процессе подготовки устройства к работе на стол 7 устанавливаетс  сосуд 8 (см. фиг. 3), подлежащий укупорке. Затем стол 7 опускаетс  до тех пор, покаторцова  кромка 16 сосуда 8 не приходит в контакт с нат нутой в горизонтальной плоскости пленкой 4, укрепленной в приспособлении 6 дл  ее нат жени . После этого под действием силового цилиндра 14 прижимна  плита 1 вместе с ножом 5 опускаетс  (см. фиг. 4), в результате чего пленка 4 прижимаетс  к торцовой кромке.16 сосуда 8 и обрезаетс  ножом 5, причем обрезка ее осуществл етс  по першиетру, размер которого больше периметра торцовой кромки сосуда. Через каналы 15 прижимной плиты 1 пропускаетс  охлаждающа  вода дл  того, чтобы плита не нагревалась до температуры, при которой возможна усадка пленки 4 прижимной плитой. Далее силовой цилиндр 14 (см. фиг. 5 и 6) опускаетс  дл  подгибани  и зафальцовывани  кра  3 пленки 4, выступающего за торцовую кромку 16 сосуда 8. Подгибание пленки осуществл етс  приспособлением 2 дл  подгибани  кра  пленки и нагревани  его, которое при этом опускаетс  ниже торцовой кромки 16 сосуда 8. Одновременно с фальцовкой и сразу же после нее через форсунку 12 продуваетс  гор чий воздухГВ результате этого выступающий за торец сосуда 8 край 3 пленки 4 поджимаетс  (см. фиг. 7) и приклеиваетс  к стенке и торцовой кромке сосуда , герметизиру  его. Воздух, подаваемый в полость II и форсунку 12, имеет посто нную температуру. в полости 11 приспособлени  дл  подгибани  кра  пленки и нагревани  его может быть установлен нагревательный элемент 17 ( см. фиг. 8). При этом, если фиксатору 9made together with a device for bending the edge of the film and heating it at the moment of clamping the film at the end of the vessel, a section; in fig. 12 is a pressing plate which simultaneously serves as a prism for the purpose of bending the edge of the film and heating it, an embodiment, a general view. The device comprises a pressure plate 1, a device 2 for bending the edge 3 of the film 4 and heating it, a knife 5 for cutting the film, a device b for stretching the film and a table 7 for vessels 8 with a lock 9 for the latter. All parts of the device are mounted on frame 10. Device 2 for bending the edge of the film and heating it is mounted concentrically to pressure plate 1 and has a cavity 11 communicating via a nozzle 12 with a source of compressed air (not shown). A knife 5 for cutting the edge of the film is located on the device 2 for bending the edge of the film and heating it, and a heating element 13, for example of a pulsed type, is mounted on the knife. The pressure plate 1 is mounted on the stem of the power cylinder 14 with the possibility of vertical movement, while channels 15 are formed in the pressure plate for supplying cold water and similar liquid. In the process of preparing the device for operation, a vessel 8 is installed on the table 7 (see FIG. 3) to be capped. Then the table 7 is lowered until the roll edge 16 of the vessel 8 does not come in contact with the horizontal film 4, reinforced in the fixture 6 for tensioning it. After that, under the action of the power cylinder 14, the pressure plate 1 together with the knife 5 is lowered (see Fig. 4), as a result of which the film 4 is pressed against the end edge of the vessel 16 of the vessel 8 and is cut off by the knife 5, and its trimming is carried out along the length of which is greater than the perimeter of the end edge of the vessel. Through the channels 15 of the pressure plate 1, cooling water is passed in order that the plate is not heated to a temperature at which shrinkage of the film 4 is possible by the pressure plate. Next, the power cylinder 14 (see Figs. 5 and 6) is lowered to bend and foil the edge 3 of the film 4 protruding beyond the end edge 16 of the vessel 8. The film is bent by means of the device 2 for bending the edge of the film and heating it, which then drops below the end edge 16 of the vessel 8. At the same time with folding and immediately after it, hot air is blown through the nozzle 12 and as a result, the edge 3 of the film 4 protruding beyond the end of the vessel 8 is pressed (see Fig. 7) and glued to the wall and end edge of the vessel, sealing him. The air supplied to the cavity II and the nozzle 12 has a constant temperature. In the cavity 11 of the device for bending the edge of the film and heating it can be installed heating element 17 (see. Fig. 8). However, if the latch 9

In the device in another embodiment (see Fig. 9), the surface 18 of the pressure plate 1, interacting with the film 4, is made concave. During operation of this device, the vessel 8 is reliably sealed even if the product 19 contained therein stands behind the end edge of the vessel. The protrusions 20 of the pressing plate 1 provide a reliable and tight pressing of the film to the end edge 16 of the vessel 8, as a result of which hot air supplied through the nozzle 12 to the end edge of the vessel 8 is prevented from entering during the technological operations. The device can be used for the continuous closure of vessels, the latter being supplied via a conveyor 21 (see Fig. 10). The vessels 8, being conveyed by the conveyor 21 to the device for their closure at a predetermined speed, are sealed and removed continuously. The tension and feed of the film are carried out from the reel 22, and the film is fed discretely at predetermined time intervals. The spent film is wound onto the drum 23. The film-closed end of the vessel 8 can be heated using a heating element 24 to reliably seal the vessel with a film.
