ЗАПОЛНЕНИЯFILLINGS

Изобретение относитс к технике упаковки сыпучих материалов в мешки, может быть применено в расфасовоч но-упаковочных автоматс1х и использоватьс в любой отрасли народного хоз йства.The invention relates to the technique of packing bulk materials in bags, can be used in packaging machines and packaging machines and can be used in any branch of the national economy.

Известно устройство дл закрывани мешков после заполнени , содержащее пресс-формы, смонтированные с возможностью перемещени 1.A device for closing bags after filling is known, which contains molds mounted for movement 1.

Однако в известном устройстве необходимо предварительно собирать горловину в жгут, что снижает надежность работы.However, in the known device, it is necessary to pre-assemble the neck in the bundle, which reduces the reliability of operation.

Цель изобретени - повышение надежности работы путем исключени ручного труда.The purpose of the invention is to increase the reliability of work by eliminating manual labor.

Поставленна цель достигаетс тем, что устройство дл закрывани мешков после заполнени , содержащее пресс-формы, смонтированные с возможностью перемещени , снабжено приспособлением дл ст гивани горловины мешка в жгут, размещенным перед пресс-формами и состо щим из рамы и шарнирно укрепленных на ней фигурных рычагов, оси шарниров которых расположены попарно на противоположных сторонах рамы.The goal is achieved by the fact that the device for closing the bags after filling, containing molds mounted for movement, is equipped with a device for tightening the neck of the bag into a bundle placed in front of the molds and consisting of curved levers on the frame whose hinge axes are arranged in pairs on opposite sides of the frame.

На фиг. 1 схематично изображено устройство дл закрывани мешков после заполнени / на фиг. 2 - разрез А-А на фиг. 2.FIG. 1 schematically shows a device for closing bags after filling / in FIG. 2 shows section A-A in FIG. 2

Механизм включает кронштейн 1, к которому прикреплены рама 2 и гидроцилиндр 3. Внутри кронштейна 1 вмонтирован пружинный компенсатор 4 шарнирно св занный со штоком гидро10 цилиндра и коромыслом 5. Концы коромысла 5 шарнирно св заны с рейками 6 и 7. Рейка б сцеплена с шестерней 8, жестко сид щей на одной оси с jwчагом 9 и с шестерней 10, жестко сид щей на одной оси с рычагом 11.The mechanism includes a bracket 1, to which a frame 2 and a hydraulic cylinder 3 are attached. Inside the bracket 1, a spring compensator 4 is hingedly connected to the hydraulic cylinder 10 shaft and rocker 5. The ends of the rocker arms 5 are hingedly connected to the rails 6 and 7. The rail b is connected to gear 8 fixed rigidly on the same axis with jwchag 9 and with gear 10 fixed rigidly on the same axis with the lever 11.

Рейка 7 через паразитную шестерню 12 сцеплена с зубчатым колесом 13, жестко сид щим на одной оси с рычагом 14 и с шестерней 15, жестко The rail 7 through the parasitic gear 12 is engaged with the gear wheel 13, rigidly seated on the same axis with the lever 14 and with the gear wheel 15, rigidly

20 сид щей на одной оси с рычагом 16.20 sitting on the same axis with the lever 16.

Кроме того, на фиг. 1 изображены мешок 17 на позиции захвата мешка с обжимом его горловины в жгут 18 (позици I) и мешок 17, запечатанный пломбой 19 на позиции II.In addition, in FIG. Figure 1 shows the bag 17 at the gripping position of the bag with the crimping of its neck in the harness 18 (position I) and the bag 17 sealed with a seal 19 at position II.

Устройство работает следуквдим образом .The device works in the following way.

В исходном положении рычаги 9, In the initial position, the levers 9,

Claims

30 11, 14 and 16 are divorced and the neck of the bag 17 has a maximum perimeter. When the piston of the hydraulic cylinder 3 moves to the left, the rocker arm 5 rotates clockwise. In this case, the rail b is moved to the left, using iriecTepHH 10 by turning the lever 11 clockwise, and gear 8 by turning the lever 9 counterclockwise. Accordingly, the rail 7 moves to the right, by means of a parasitic two-gear gear 12 and a gear wheel, 13 turning the lever 16 counterclockwise. As a result of the descent of the levers in the center (position I), the st. Neck of the bag 17 into the tight bundle 1. The pull of the bundle is reached by stretching the springs with compensators when the piston of the hydraulic cylinder 3 moves to the extreme left position. The seized bag, together with the whole mechanism, moves to position 11 to seal the bag with an annular plastic seal 19. At position II, with the piston stroke of the hydraulic cylinder to the right, the levers 9, 11, 14 and 16 return to their original position, freeing the neck of the sealed bag. The mechanism then returns to position I to capture the next bag. The proposed device eliminates manual labor and thereby increases the reliability of the device. Claims An apparatus for closing bags after filling, containing molds mounted for movement, characterized in that, in order to increase reliability by eliminating manual labor, it is equipped with a device for shrinking the neck of the bag into a harness placed in front of the molds and consisting of frames and figured levers hinged on it, the axles of which are located in pairs on opposite sides of the frame.
