FIELD: transport, package. ^ SUBSTANCE: set of invention relates to device and method of proportioning and packing. Proposed device comprises product feeder 170 with pump to allow a continuous volumetric flow, packing tube 20 connected to feeder 170 and intended for providing the stock 32 of sleeve-type package 30 that can be removed from tube 20 together with packed product. Besides proposed device comprises clamping device 150 fitted downstream of tube 20 to press filled package 30 into bundle during filling and pressing of clamping element 162 around said bundle. It has also retaining device 100 that embraces tube 20 along its edges and brake ring 110 that reciprocates parallel with the former to cause friction forces to act on package 30 in its removal. Clamping device 150 incorporates control device designed to generate squeezing and clamping force proceeding from selected portion size and continuous volumetric flow and to feed control signal to clamping device 150. Brake ring 110 is moved back on packing tube 20 towards direction of removal into position of packing volume release directly before of during squeezing and clamping. After clamping it moves forward on said tube 20 in direction of removal into working position. Product squeezed is forced into free packing volume and, after clamping, forced again into removed package 30. ^ EFFECT: higher efficiency of proportioner. ^ 21 cl, 2 dwg |
