Description

A group of utility models relates to filling and packaging equipment and can be used at dairy enterprises for dispensing grain curd, as well as in other industries where packaging of plastic or viscous products, as well as bulk ones prone to clumping, is required.

The subject of the utility model are two objects:

- packaging machine in general

- her metering unit.

A device is known for filling containers with a plastic product, mainly cottage cheese [see RF patent for the invention No. 2169683, 2001]. The device contains a feeder, a metering carousel with measuring sleeves, an ejecting piston and a device for supplying containers. A recess is made in the working part of the piston, the diameter of which at the end of the piston does not exceed the diameter of the piston, and channels are made in the piston body that communicate with the cavity of the recess with a source of compressed gaseous medium. The output sections of the channels can be located at an angle to the axis of the piston so that their geometric axis pass through the zone of the edges of the working part of the piston.

The main problem that arises with automatic strictly dosed packaging of such a product as cottage cheese is its viscosity. In this case, the accuracy of dosing of grain curd is complicated by the coalescence of grains and clumping of the loaded product.

Due to the fact that in the described analogue the product is fed into cups located in the carousel, using a pushing piston this device is not applicable for the packaging of cottage cheese, as squeezing by a piston leads to a violation of the granular structure of the product.

As a prototype for both of the claimed objects, the PASTPAK-R rotary-type filling and packaging machine and dispenser for it were selected [see RF patent for utility model No. 45981, 2005]. The machine performs automatic packaging of liquid and pasty products in plastic cups, hermetically sealing them with aluminum foil lids with thermo-varnish coating. All mechanisms and blocks are located on the machine bed: 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 dispenser described in patent No. 45981, adopted for the prototype of the second object, incorporates a loading hopper, under the outlet part of which there is a screw chamber with a hollow spiral screw fixed therein (an axial spiral pusher). At the exit of the auger chamber, a curd baking powder is installed, which is a drum with radial teeth on the outer surface. The baking powder is equipped with a gear motor, and its axis is oriented horizontally. A vertically oriented storage hopper is located under the baking powder, equipped at the bottom with a product shut-off - a slide gate, controlled from the signal of the weight meter - strain gauge. The means for supplying containers (cups) is equipped with a lift installed directly on the packaging machine with the possibility of reciprocating vertical movement, the drive of which is connected with a strain gauge.

The disadvantage described in the prototype dispenser is the low efficiency of the baking powder, the radial teeth of which are clogged with cottage cheese grains during operation, and it ceases to fulfill its function. Lumps entering the collecting hopper reduce dosing accuracy. In the prototype, the packaging of cottage cheese is carried out in plastic cups, it does not provide for packaging in plastic bags. However, the packaging of dairy products in plastic bags is widely used and is in steady demand among consumers, but is not available on the market for grain curd. The task solved by the utility model is to expand the arsenal of funds and satisfy the existing need - to create a filling and packaging machine and dispenser that carry out precisely dosed packaging of grain curd in plastic packaging bags. The technical result achieved is an increase in the dosage accuracy of granular products prone to clumping during packaging in plastic bags by loosening the lumps and preventing secondary clumping of the product (grain curd) during packaging.

The problem is solved by both objects of the utility model.

The inventive filling and packaging machine has a frame on which is mounted a device for unwinding the packaging roll of polymer material, as well as devices forming the packaging bag, namely: a collar and a pipe forming a sleeve from the packaging material, a device for automatically centering the packaging material on the collar, device for broaching a sleeve, a longitudinal welding jaw intended for forming a longitudinal seam of a package, transverse welding jaws with a cutting knife are designed for forming end joints with the product package placed therein. A doser is also installed on the frame, which has a loading hopper, a screw chamber with a non-axial spiral conveyor, a vertically oriented storage hopper equipped with a product cutter in the lower part controlled by a strain gauge signal. Inside the storage hopper, a baking powder is installed coaxially with it, having an axial shaft, the upper end of which is connected to the gear motor, and the lower is free. Mixing elements fixed along the walls of the storage hopper are fixed on the baking powder axial shaft. Under the storage hopper there is a dosing tank with a second product cutter controlled from the strain gauge sensor, and said tube forming a sleeve is located under the dosing tank. A control system for the operation of the machine located in a control cabinet equipped with a control panel is also fixed on the frame.

The second object of the utility model is the dispenser included in the patented machine. However, this dispenser is an independent object of protection, as can find application for any other products whose packaging requires an exact dosage. The dispenser incorporates a loading hopper, under the outlet part of which there is a screw chamber connected to it with a non-axial spiral conveyor fixed in it, which is designed to feed the product from the screw chamber into a vertically oriented storage hopper. The storage hopper is equipped in the lower part with a product cutter controlled from the signal of the strain gauge sensor and is also equipped with a baking powder with a gear motor. The claimed dispenser differs from the prototype in that it additionally contains a vertically oriented dispensing tank located under the storage hopper and equipped with a second product cutter controlled from the strain gauge signal. The base of the dosing tank is mounted on the console of the strain gauge. The baking powder is installed inside the storage hopper coaxially with it, and has an axial shaft, the upper end of which is connected to the gear motor, and the lower one is free. Mixing elements are fixed on the axial shaft, oriented along the walls of the storage hopper spaced from the walls with a given clearance.

The mixing elements of the baking powder can be made of rods curved in the form of spiral fragments and fixed to the axial shaft with radial fingers, or in the form of plate scrapers curved in the form of spiral fragments and fixed on the axial shaft with radial fingers.

The mixing elements can be fixed on the axial shaft of the baking powder tier.

In order to better demonstrate the distinctive features of the utility model, as an example, which does not have any restrictive character, the preferred embodiment described below is embodied in the PITPAK model range machine, which is used for packing and packing grain curd in plastic film bags .

An example implementation is illustrated by the figures of the drawings, which show:

Figure 1 - filling and packaging machine

Figure 2 - dispenser,

Figure 3 - storage hopper.

The filling and packaging machine has a welded metal frame 1, on the top plate of which a dispenser 2 is installed.

On the frame 1 there is also a device for unwinding 3 packaging roll polymer material, equipped with its own gear motor. Inside the frame there are rollers, a collar, and a pipe designed to form a sleeve (not shown in the Figures). The collar is a spatially complex figure formed by curving a flat surface to the shape of a cylinder. The pipe is made of stainless steel and is located vertically in the holder mounted on the top panel of the machine. It performs two functions: feeds the product into a bag and is an emphasis for the longitudinal welding jaw during the formation of the longitudinal seam.

At the lower end of the pipe there are shapers that stretch the film before welding with transverse welding jaws. There is also a device for broaching the sleeve, a longitudinal welding jaw, designed to form the longitudinal seam of the package and transverse welding jaws with a cutting knife, designed to form the butt welds of the package with the product placed in it. Also on the frame is fixed a control system for the operation of the machine, located in the control cabinet 4, equipped with a control panel.

The dispenser has a loading hopper 5 connected to a horizontal auger chamber 6 with an axisless spiral conveyor 7. The outlet of the auger chamber 6 is connected by a flange transition to a vertically oriented accumulating hopper 8, equipped with a product cutter 9 (slide gate) in the lower part controlled by a signal from the system strain gauge management. Inside the storage hopper 8, a baking powder is installed coaxially with it, having an axial shaft 10, the upper end of which is connected to the gear motor 11, and the lower one is free. On the axial shaft 10 are fixed mixing elements oriented along the walls of the storage hopper. The mixing elements are mounted on the shaft 10 using radial fingers 12 and are installed at an angle to the axis.

The mixing elements of the baking powder can be made of rods curved in the form of spiral fragments, or, as shown in the Figures, in the form of sickle-shaped scrapers 13, curved in the form of spiral fragments. Scrapers 13 are made of metal strips (plates). The mixing elements can be arranged in two tiers, several at the same level, for example, 4 pieces on the upper level, equally spaced from each other, and two on the lower, diametrically opposite.

Under the storage hopper 8 a metering tank 14 is installed, made in the form of a cylinder (pipe section). The dosing tank is equipped with a second product cutter 15 (second slide gate) controlled from the signal of the strain gauge sensor. The base of the dosing tank is installed on the console of the strain gauge sensor of the control system.

The device operates as follows.

A roll of packaging material is mounted on the rear side of the frame on a pneumatic shaft, where it is clamped with cams when air is supplied by a pneumatic gun. From the roll, the packaging material extends through a swaying arm, the deviations of which, monitored by proximity sensors, guarantee a constant, fairly free supply of packaging material, necessary for uniform pulling up.

The packaging material is pulled through a system of rollers to a collar, on which it is rolled up to the shape of a sleeve and moves further along the pipe to the welding jaws. A sensor is mounted on one of the rollers, designed to measure the length of the bag and control the drawing of the packaging material. On the pipe, a longitudinal seam of the package (longitudinal welding) is formed by a longitudinal welding sponge. Under the pipe, the sleeve of the packaging material enters the space of the transverse welding jaws, where the welding and cutting of the finished package with a cutting knife takes place.

The feed is blown into the formed bag by dispenser 2 as follows.

Grain cottage cheese is fed into the loading hopper 5, from which it enters the auger chamber 6, where, using an axisless spiral conveyor 7, additionally gently mixing, moves to the input of the storage hopper 8. In the storage hopper 8, the curd is directed downward, while it is affected by the mixing elements of the baking powder, which rotate from the gear motor. When mixing in the storage hopper, the loose lumps of grain curd due to the action of mixing elements break up into smaller fractions. Due to the fact that the rods or scrapers are bent in the form of spiral fragments, mixing occurs in the entire volume of the storage hopper. Larger adhering lumps, or lumps with greater grain adhesion to each other, during the mixing process are pushed to the periphery of the hopper and fall into the zone of intensive mixing and direct exposure to mixing elements. The tiered arrangement of the mixing elements contributes to more efficient grinding of lumps. It is established that the described construction does not lead to a violation of the structure of individual grains and a change in the fractional composition.

During the supply of the product, the first slide gate is open and the product, passing the opening of the lower base of the storage hopper, enters the dosing tank 14. When the set portion weight of the product is set, the strain gauge is activated and the first slide gate closes at its signal. The product that remains in the working area of the baking powder remains in the storage hopper, thereby achieving the exact dosage of the product. After actuation of the strain gauge sensor, its slide gate opens (second cutter), and the product enters the packet formed as described above. The package is brewed and trimmed.

The design of the machine provides means for applying to the surface of the package of shipping information in the process of its formation.

Thus, in the packaging process, the grained cottage cheese fed into the machine not only does not worsen its granular structure, but improves it, acquiring the original friable consistency. Breaking up existing lumps during packaging increases the accuracy of dosing.
