Description

The proposal relates to dosing equipment and is intended for use in the food industry, mainly for dosing a product such as cottage cheese, before its subsequent packaging.

It is preferable to use the claimed technical solution for filling and packaging machines, for example, rotor type, designed for dosed packaging plastic products in plastic cups, followed by sealing with foil and capping with a plastic lid.

Known methods for volumetric dosing of plastic products consist in feeding (with a screw or piston) with a constant force of the dosed product from the feeder into the measured capacity of the nominal volume for a predetermined period of time sufficient to guarantee the filling of the specified capacity. The dosing accuracy in this method is achieved by the fact that the product is supplied from the feeder to a measured container in an excess amount slightly exceeding the set dose, and the excess product coming from the feeder is cut off from the measured tank, after which the product is unloaded.

The prior art ice cream dispenser, operating in accordance with the aforementioned dispensing technology, comprising a consumable container connected to a measuring chamber with openings mounted for rotation, freely mounted in the chamber

floating piston (see copyright certificate SU No. 1685790, B 65 V 3/12, 10/23/1991, Bull. No. 39).

The main disadvantage of this device is the narrow scope, namely, the ability to dispense only fluid products, when dosing plastic products there are significant errors in the measured dose.

It is also known a device for filling cans with a product containing a feeder, a metering device, including a carousel with measuring sleeves reinforced around its circumference, at least one eject piston and a container feeding device (see copyright certificate SU No. 581009, 65 V 3 / 12, 11/25/1977, Bull. No. 43).

This device does not provide accurate dosing of the product, which is due to its sticking to the surface of the working part of the piston when pushing the product out of the measuring container and the ablation of part of the dose. To a large extent, this applies to such a viscous and plastic product as cottage cheese, especially traditional Russian cottage cheese, which is characterized by high adhesion to almost any known structural material - metals, plastics, wood.

Known technical solutions, including regular wetting of the ejecting piston to reduce the phenomenon of sticking cottage cheese on it. However, this solution cannot be called acceptable, since it leads to a dosage violation and the introduction of a foreign substance, a wetting liquid, into the dose of the product.

Also known is a device for pumping and evacuating viscoplastic food products such as minced meat, dough, cottage cheese (see patent RU No. 2035151, A 22 C 11/08, 1995). The device comprises a loading hopper, a screw blower, a nozzle for connection to a vacuum system, a discharge nozzle, a chamber located between the hopper and a screw blower and communicated through slit-shaped openings

and nozzles with an autonomous vacuum system, a roller feeder mounted in the upper part of this chamber.

This device allows for double evacuation of the product, and experimentally proves that such a perfect vacuum treatment of the product reduces its stickiness by 40-50%, and as a result sticking, for example, cottage cheese on the surface of the device. This increases the accuracy of dosing, however, in general, the device acquires significant dimensions and high energy intensity.

The closest in technical essence to the claimed solution is a device for filling containers with a plastic product, mainly cottage cheese, containing a feeder, a dosing device and a device for feeding containers (see patent RU No. 2169683, 65 V 3/12, 2001).

The disadvantages of the known device are the complexity of the design and the narrow scope, namely the impossibility of dosing, for example, granulated cottage cheese, which is in constant demand among the modern consumer. However, many milk processing enterprises encounter certain difficulties in its packaging, since due to the granular structure with a dense consistency of grains, such cottage cheese is easily damaged during the dosing process.

The technical result of the proposal is to improve the operational and technological capabilities of the dispenser, mainly as a part of the packaging machine, first of all, simple in design and convenient to use, and at the same time, allowing to expand the range of dosed products by packing cereal curds.

Thus, the dispenser must deliver the exact weighted dose of the cottage cheese to the package, while the packaging machine with this device must have high productivity.

To achieve the indicated technical result, in a dispenser containing a loading hopper, under the outlet part of which there is a screw chamber connected with it with a screw fixed therein and having means for supplying containers, according to the proposal, the screw is formed from a flexible spiral feeding the product from the screw chamber through the neck into the storage hopper, over which there is a baking powder, made as a drum with teeth over the entire surface, installed with the formation of a calibration gap between it and the neck and with rotation capacity from a drive, wherein the collecting hopper is configured to shut off the product at the outlet, and means for feeding containers provided with a lift mounted to a reciprocating vertical movement and equipped meter weight dispensed product, which in turn is connected to shut off the control system.

The presence of distinctive features, namely, the execution of the screw in the form of a flexible spiral, the placement of the neck at the product exit from the screw chamber, the execution of the storage hopper with the product cut-off at the outlet, the placement of the baking powder in the form of a drum with teeth over the entire surface, its installation with the formation calibration gap between it and the neck and with the possibility of rotation from the drive, the implementation of the means for supplying containers with a lift, which is installed with the possibility of reciprocating vertical displacement and is equipped with a meter of the weight of the dosed product, and is also connected by a control system with a cutter, indicates the compliance of the claimed technical solution with the patentability criterion of "novelty".

The essence of the proposal is illustrated by drawings, where in Fig.1 shows a General view of the dispenser in a perspective view; figure 2 schematically shows a front view of the dispenser; figure 3 schematically shows the auger dispenser; figure 4 presents a General view of the packaging machine model "PASTPAK-R", equipped with the inventive dispenser and container lift.

It should be noted that in the drawings for clarity only those details are presented that are necessary for understanding the essence of the technical solution, and related equipment, well known to specialists in this field, is not shown in the drawings.

In the presented embodiment, the proposed dispenser is installed in a filling and packaging machine of the rotary type model "PASTPAK-R".

General view of the packaging machine "PASTPAK-R" is presented in figure 4.

The machine is designed for automatic filling (volumetric dosing) of liquid and pasty products in plastic cups, hermetically sealing them with aluminum foil lids with thermo-varnish coating.

The design of the machine provides work in two modes: automatic and manual during commissioning.

The machine’s base is a bed on which all mechanisms and units are located: a rotary disk, a cup feeding unit, a dispenser, an aluminum foil feeding unit, a cup sealing unit, a date setting device, an ejector, a finished product receiving table, an electric cabinet, an air preparation unit.

The machine bed is made in the form of a frame welded from rectangular pipes, covered with a steel plate. In the center of the plate is the support of the rotary disk. Evenly around the circumference of the disk, ten holes were made with inserts for cups installed in them.

The drive of all mechanisms is pneumatic, except for the drive of the rotary disk. The rotation of the disk is carried out using a discontinuous drive, namely, the Maltese mechanism.

The machine operates as follows. First, the machine is prepared for work, that is, the dose of the product is set, the cup and lid supply units made of aluminum foil are filled, and the pipe is connected to the food container. Then, after starting the Start button, automatically

the machine performs the whole cycle of operations with a given rhythm from loading an empty cup to giving the sealed cup with the product to the finished product. The operator’s job is to replenish the cup, lid and cup dispensing units and remove packaged cups during the change of the product.

A general view of the dispenser is shown in FIG.

The device includes a screw chamber 1, which is made of caprolon in the form of a half-cylinder in the form of a horizontal horizontal gutter open on top and fixed to the base 2 with an essentially steel mounting plate by fasteners, for example, studs. At the ends, the screw chamber 1 is closed by flanges 3, 4, and the hopper 5 is mounted on top of it. It is a welded structure in the form of an inverted truncated pyramid that has no bases, while this structure is fixed with studs on the lateral horizontal surfaces of the screw chamber 1 in this way that their internal spaces form a combined free volume for receiving and further unimpeded transportation of grain curd.

From one end of the screw chamber 1, a steel stepped shaft 6 is installed on the flange 3, one end of which is placed in the screw chamber 1 (figure 2). At this end, a sleeve 7 is fixed with a screw 8 mounted rotatably from the drive 9, located on the other end of the shaft 6. Thus, the screw 8 is completely located in the inner space of the screw chamber 1, and the second end is not fixed. The screw 8 is made flexible, without an axial rod and is a spiral - spring, twisted from a steel bar, working as a screw (screw) and moving the product during rotation (figure 3).

From the other end of the screw chamber 1 to the flange 4 is fixed and mounted on the mounting structure perpendicular to the horizontal axis of the screw chamber 1 and at some distance from it, the baking powder 10, mounted for rotation from the drive 11. The baking powder 10 represents

a drum made of fluoroplastic with teeth along its entire outer surface. And in the resulting space between the auger chamber 1 and the baking powder 10 there is a neck 12 made in the form of a pipe with a flange of a metal channel and installed with a calibration gap for the passage of the product with the outer surface of the baking powder drum 10. An accumulating hopper 13 is placed directly under the baking powder 10 in the form of a bulk funnel, attached by an arm 14 to the base 2. In the lower part, the storage hopper 13 is equipped with a shut-off device 15 in the form of a slide gate installed with the possibility of return atomic-translational movement.

The device also includes a container lift 16 mounted directly on the packaging machine with the possibility of axial vertical movement to isolate the container, which is brought under the storage hopper 13, from contacts with the surface of the rotary disk. The container lift 16 is provided with a strain gauge element.

The device operates as follows.

The product, for example, cottage cheese, is fed into the hopper 5, from which it freely enters the screw chamber 1. Before dosing, the container is lifted by the container lifter 16, thus freeing it from any contact with the inner surface of the holes of the rotary disk of the machine, after whereupon a container, for example a glass, is weighed. Then, from the drive 9, the screw 8 starts its rotation, carefully moving the cottage cheese with its spiral from the screw chamber 1 to the neck 12, and then to the baking powder 10.

The baking powder 10, rotating from the drive 11, breaks the lumps of the product with its teeth, preventing the cottage cheese from getting large pieces into the storage hopper 13. Thus, through the calibration gap between the neck 12 and the baking powder drum 10, the mass of cottage cheese with almost the same grain size enters the storage hopper 13 .

When this shutter 15 is open, and the product enters the container. Then, when filling the container, and essentially when fixing it with the strain gauge element, to achieve the desired product weight in the cup, the shutter shutter 15 closes. When this auger 8 and baking powder 10 are stopped, the container lift 16 is lowered.

On this, the operation of the device is completed.

A cup with cottage cheese is served further at the positions of laying and sealing foil, setting the date, etc. And at the dosing position in the hole of the rotary disk serves the next empty cup. The cycle repeats.

Due to the fact that the flexible rodless spiral screw carefully moves the curd mass without injuring the grain, and the baking powder does not allow the curd to fall into the storage hopper in large pieces, the curd does not deform, preserving its structure and presentation. And the addition of the device to a weighing system based on a strain gauge element allows to achieve high accuracy and dosing speed.

The simplicity of the design, the simplicity of manufacture, reliability in operation are the basis for widespread use of the proposed dispenser for the packaging of cottage cheese.

The device was developed and manufactured at the TAURAS-PHOENIX engineering plant and was successfully used at the customer’s enterprise.

From the above it follows that the manufacture of this device in an industrial way does not cause difficulties, involves the use of developed materials and standard equipment, which indicates the compliance of the claimed technical solution with the patentability criterion of "industrial applicability".
