SU426917A1 - DEVICE FOR MANUFACTURING. FILLING UP AND SEALING THE MESHKOVIZ OF THE SLEEVE THERMOSLASTING MATERIAL FRONT S'iSflEPTOB - Google Patents

Description

The invention relates to the field of packaging industry in the industrial industry, as well as to a device for the manufacture, filling and sealing of bags from tubular terlysklei vayush, egas of the Material, and can be used for packaging bulk, paste-like and liquid products. A similar device is known, comprising a roll holder of a flat-laid sleeve, guide rollers, a frame with a hollow mandrel pivoting about the horizontal axis and a device for forming transverse seams. The known device has a low productivity and does not provide for creating a vacuum inside the dresser. A distinctive feature of the proposed device is that the mandrel and the device for forming transverse grooves are mounted on the frame on the guides with the possibility of reciprocating movement in the radial direction of the frame. FIG. 1-7 schematically depicts the proposed device in various operating positions, a longitudinal section. The device consists of a roll holder / flat-laid sleeve 2, guide rollers 3 rotatable about the horizontal axis 4 of the frame 5, with a hollow mandrel 6 mounted on it, and a device 7 for forming transverse seams moving reciprocatingly in the radial direction relative to the frame 8 using sliders 9 along guideways W, which are reinforced with sleeves / on a swing frame 8. The floor of the mandrel 6 has elastic spacers 12 and is supported by the rollers 13 built into it on the support rollers 14 and above its throat It is a feeder 15. The conveyor 16 is arranged on the rotary frame 7. The device operates as follows. The device is prepared for operation (Fig. 1), while the flat-folded tubular film 2 is unwound from a roll installed in the roll holder 1, is passed through a system of guide rollers 3 and is put on the mandrel 6 and envelops the latter until it reaches the level of the device to form transverse seams. Next, the internal cavity BO of the mandrel 6 enters the product from the feeder 75, while the fixture 7 for forming the transverse joints is reduced, forming the bottom of the bag 17 and sealing the internal closed volume of the film 2 (Fig. 2), consisting of the volume occupied by the mandrel 6 and the free cavity 18. The pivoting frame 8 is then rotated with the mandrel 6 and other mechanisms by 180 ° around axis 4 (Fig. 3).

After this, the basement frame 4 with the support rollers 14 and the support frame 6 installed on it moves along the points 10 until the sliders 9 rest against the bushes /) (Fig. 4), and the bag filled with the product is kept in the same position with the help of the device 7 to form cross seams. The mandrel 6, moving along the guides 10, pushes the walls of the cavity 18 inside the film 2, thus increasing the inner closed volume of the film. This leads to the fact that (inside the closed volume and inside the manufactured bed 17 there is a vacuum, the depth of which is governed by the stroke of the oiratac 6 by changing the position of the sleeves 5.

Then the device for forming the transverse seams 7 is diluted (Fig. 5) and moves upward along the guides 10 to the required level, after which the device 7 is diluted and the film is clamped, sealing the bag 17 (Fig 6). At the same time, the finished bag is separated from the film and lowered under the weight of its weight onto

the conveyor 16 is removed from the device (Fig. 7). In this case, the remaining sleeve film 2 is held and pulled between the support rollers 14 and the rollers 13 of the mandrel 6 with the help of a device moving down along the guide JO to form transverse seams with simultaneous movement of the mandrel 6 and unwind from the roll.

Subject invention

A device for making, filling and sealing bags from a bag-type heat-sealing material, comprising a roll holder of a flat-laid sleeve, guides the rollers, swiveled relative to the 0 horizontal axis of the ax, a radial with a hollow mandrel, and a device for creating transverse cross sections, characterized by In order to increase the size of the device, to create 1 bag of bag and bag, the mandrel and the tool for the design of transverse welders are mounted on the guides

with the possibility of automatic displacement in the radial direction of the frame.
