Description

Technical solution - a utility model relates to packaging technology, namely, portioned packaging devices and can be used in the food industry for packaging small portions of a paste-like product in individual stick packages made of thermoplastic film.

In the food industry, devices for portioning pasty products into individual stick packaging are devices containing a shaper of a stick bag of a thermoplastic film, a welding unit consisting of thermal heating elements or ultrasound sources for the formation of one or more longitudinal joints, and also a transverse seam, a unit for supplying a product to an formed package and a unit for cutting off finished products.

The vast majority of devices operate according to the principle described above and contain the listed components in various design combinations.

The closest in technical essence to the proposed technical solution is the device for portion packaging of pasty products in a thermoplastic film [1], taken as a prototype and including a shaper of the packaging blank in the form of a sleeve from a thermoplastic film, a shaper of longitudinal and transverse sealing joints of the package, the unit for introducing the product into the package .

The unit for introducing the product into the package contains a metering device, the blank former includes a roll holder for the tape being welded, a sleeve former, a vertical pipe for introducing the product into the sleeve, a device for forming a longitudinal seam and welding-cutting elements for forming transverse seams and separating portioned packages.

The device adopted for the prototype works as follows. The packaging material is fed through a bending roller to a sleeve former, where a sleeve is formed around a vertical pipe, which is pulled down by closed heating elements-bars with the simultaneous formation of a longitudinal weld by means of a welding roller. When the pipe from the packaging material interacts with the heating elements - bars, a transverse seam is formed, which is the bottom of the package, and the previous finished package is cut off from the sleeve with a knife. The product to be packaged is fed into the hopper, from which, using a dosing device, it enters the pipe around which a sleeve of packaging material is formed. Thus, the sleeve is filled with a portion of the product, and with further advancement of the sleeve, a transverse seam is formed, which is upper for the packaged portion of the product and lower for the next.

The described device allows the manufacture of stick-bags representing a rolled-up sleeve, from which a pasty product can be squeezed out without hindrance in case of violation of the integrity of the package (tearing by the consumer during use). The disadvantage of this type of packaging is that the dosing of the pasty product during extrusion occurs unevenly, which greatly complicates its use by an individual user, for example, when applying butter to bread.

However, currently known packaging for pasty products [2], equipped with two rigid plates inside the package. Such a package after opening will allow you to squeeze a pasty product through the outlet in the form of a tape (for example, butter on bread) of a given width. In this case, there is no need to use a knife to distribute a pasty product [3].

Thus, given the need to manufacture a new type of packaging, the main technical disadvantages of the device adopted for the prototype are:

1. The inability to feed and welding to the inner surface of the formed package of two rigid plates located relative to each other with a gap between them. This is due to design features (sleeve formation on the sleeve former) of the prototype does not allow for the formation of a new type of packaging.

2. Low quality of the weld and the presence of possible violations of the tightness of the package. This is due to the formation of seams by the thermal method and leads to its use in the packaging of dry mixes and not to use for packaging liquid or pasty products.

3. The inability to ensure when using the prototype the introduction of the product into the package through the channel formed after welding to the inner surface of the package two hard plates.

The proposed technical solution is a useful model aimed at eliminating the shortcomings of the existing device, namely, to create a device for forming a new type of portioned packaging of pasty products in a thermoplastic film, equipped with rigid plates on the inner output of the stick bag for uniform application of the extruded product.

The essence of the proposed technical solution lies in the fact that in the known device for portion packaging of pasty products in a thermoplastic film, comprising a shaper of the packaging blank in the form of a sleeve of thermoplastic film, a shaper of longitudinal and transverse sealing joints of the packaging, the unit for introducing the product into the packaging, the shaper of the packaging blank is made in in the form of nodes of synchronous unwinding of two rolls of thermoplastic film, the width corresponding to the transverse size of the portioned packaging. The shaper is additionally equipped with nodes for feeding and welding onto the inner surface of the formed package of rigid plates, the length of which is less than the transverse size of the package by the width of two longitudinal joints of the formed package. The shaper of the longitudinal and transverse sealing seams of the package and the welding unit on the inner surface of the formed package of rigid plates contains ultrasonic sources, each of which is made in the form of sequentially installed and acoustically coupled working tools with a radiating surface of a given shape, a concentrator and a piezoelectric transducer connected to the generator. The unit for introducing the product into the package is equipped with a needle whose transverse size corresponds to the transverse size of two rigid plates welded to the inner surface of the package, the internal size of the needle provides the required filling performance, and the longitudinal size of the needle ensures its movement along the entire length of the package when it is filled.

The device for portion packaging pasty products in a thermoplastic film is schematically illustrated in FIG. 1 and FIG. 2, on which the following designations are adopted: 1 - source of ultrasonic action, 2 - welding support of cylindrical shape, 3 - axis of rotation, 4 - bearing assembly; 5 - mounting bracket; 6 - displacement pneumatic cylinder for a longitudinal seam; 7 - a source of ultrasonic action for welding a transverse seam; 8 - knife pieces of portioned packaging; 9 - mounting bracket; 10 - pneumatic displacement cylinder for the transverse seam; 11 - an arm of fastening; 12 - welding-cutting support; 13 - guide tapes; 14 - a hopper for a product; 15 - a needle; 16 - node unwinding thermoplastic film; 17 - envelopes; 18 - holder; 19 - store with hard records; 20 - source of ultrasonic action for welding a rigid plate and film; 21 is a device for supplying hard plates to the welding zone.

The unit portion packaging of pasty products in a thermoplastic film works as follows. Using the unwinding unit (16), the thermoplastic film is stretched through the envelopes (17), the guide films (13), and the longitudinal seam welding unit (the film is stretched between the ultrasound source (1) pressed by the pneumatic cylinder (6) and the cylindrical welding support (2) rotating around axis (3) fixed by means of a bearing assembly (4) on the bracket (5), the length of the package is measured, at the end of the formation of the longitudinal seams, the transverse (closing) seam is formed (the seam is formed by ultrasonic action on the sandwiched between the support (12) and the ultrasound source (7) fixed in the bracket (9) and driven by the pneumatic cylinder (10) mounted on the bracket (11), a short longitudinal seam is made (the cut-off zone of the bag is formed), at the end of the formation of the cut-off zone a second horizontal seam is made (the bottom of the bag). The formed and filled bag is cut off with a knife (8). The hard plate feeder (21) feeds the plate from the magazine (19) fixed on the holder (18) to the ultrasound source (20) after which a weld is formed between the thermoplastic film and the rigid plate. Together with the feeding of the plate from the magazine (19), the filling needle (15) is fed into the formed bag, the dispenser is turned on and the needle (15) starts to rise (the feed rate (stored in the hopper (14)) is selected so that the entire space under the needle (15 ) managed to fill up with the packaged product). At the end of filling the bag with the product, the cycle repeats.

The appearance of the designed and manufactured device is shown in FIG. 3.

The device is being prepared for industrial use in the conditions of a small innovative enterprise, Center for Ultrasonic Technologies LLC.
