Description

 The manufacture relates to techniques for the manufacture of sealed packaging, packaging liquid products in them and can be used in medicine, animal husbandry, veterinary medicine; in the pharmaceutical, food, chemical, biological industries.

 The famous machine of the Swedish company "Tetra Pak" and the Italian "Fata" for packaging liquid products in pre-made paper or in combination with plastic packaging. It consists of a disinfecting unit, a packaging manufacturing device, a dosing device and thermal sealing.

 The machine has the following disadvantages: it is bulky and is operated only in stationary conditions; to ensure the packaging of the liquid object is equipped with a special dosing device; in the absence of a liquid object, it is not used; packaging of the object in packaging is possible only if there is electricity in the network.

 Known molding and filling machine M6-OP2-D-2 (Kapsuksky factory of food vending machines named after the 50th anniversary of the USSR), which includes mechanisms for feeding films, a matrix for forming cells, a feeder, a dosing device, a mechanism for heat-sealing films and a cutting device.

 The main disadvantages of the machine are: its low productivity due to the small one-time volume of filling the boxes (4 6 pieces) with a dispenser; non-compliance with tightness when filling packages with a liquid product, which contributes to its contamination with microorganisms; elimination of the possibility of filling containers with a liquid product without the use of a metering device; the impossibility of packaging the product in packaging in the absence of electricity in the network; liquid product packaging is possible only under stationary conditions; the machine is idle in the absence of a liquid product.

 Another type of domestic machine 213 is known for packaging tablets in blister packs.

 The device consists of mechanisms for unwinding films, a heater, a matrix for forming cells of a drum (cylindrical) type, a storage device for tablets, a unit for thermo-gluing films, a unit for cutting packages with tablets and a cutting device for film waste.

 The disadvantages of the device: it is intended for packaging piece products.

 The objective of the present invention is to increase productivity, ensure tight filling, as well as self-dosage of a liquid product.

 This goal is achieved by the fact that the mechanism of thermal bonding of two films, a cutting device, a feeder are installed in the course of the technological process behind the matrix, in which the recesses are made to form channels connecting the cells on the film, and a mechanism for transmitting these channels and sealing them is installed behind the feeder.

 Comparison of this device not only with the prototype, but also with other technological solutions in the art showed that it has a new set of essential features.

 In FIG. 1 shows a diagram of a first embodiment of a device for manufacturing containers of film material and dosing them with liquid product.

 The device consists of a film feeding mechanism, including a lower film unwinding unit 1, an upper coating film unwinding unit 4 and a heater film 2 unwinding unit 9, a cell forming matrix 3 and a recess for performing mechanism 5 on the lower film of channels connecting the cells to each other thermal gluing of two films, a cutting device 6, a feeder equipped with a hose (tube) with a tip 7 for supplying a liquid product to the package, a channel transmission mechanism 8 and their sealing.

 The device operates as follows. When you turn on the drive of the device, the torque is transmitted to the mechanism 9 for winding the waste films of the lower and upper layers. The lower film from the unwinding unit 1 through the heater 2 is fed to the matrix 3 of forming cells and recesses connecting the cells, where the cells and recesses connecting the cells are formed by the pneumomechanical method. The molded blocks of cells with recesses are sent to the mechanism 5 for thermal bonding of two films. The sealing coating film is unwound from block 4, superimposed on the molded lower film, thermally glued, forming a block of containers with communicating channels. After heat sealing, the container block enters the cutting device 6, where it is cut off, forming a separate multi-cell sealed package.

 Sealed packaging is a multi-cell container. The cells are interconnected by channels for sequentially filling the cells with a liquid product. The cells are interconnected by channels both sequentially and parallel-sequentially. When the capacitances of the cells are connected in series, the packaging is filled from the first cell to another and so on to the last. With parallel-serial connection of the capacities of the cells, packaging is simultaneously carried out in two or more capacities of the cells.

 Each package has inlet and outlet channels.

 Sealed packaging serves to the feeder 7, equipped with a hose with a tip. They pierce the supply channel of the packaging with a tip, if necessary, tightly fasten them and use a gravity-filled liquid product or fill all packaging containers under pressure. To ensure filling, a discharge channel is punctured to let air out of the package. A package filled with a liquid product is fed under the mechanism of channel pressing and sealing 8, after which a package is presented representing metered containers of containers, which are placed in a secondary container.

 In FIG. 1 shows only the first possible variant of the device.

 If instead of a flat fixed matrix, the device is equipped with a cylindrical (drum) matrix (Fig. 2) or the matrices are placed on the Maltese cross (a mechanism for converting continuous rotational motion into intermittent one direction, Fig. 3), then the two films are thermo-glued on the matrix (s) molding.

 The device with a cylindrical matrix consists of a mechanism for unwinding the lower film 1, a heater 2, a cylindrical matrix 3. The thermo-adhesive drum 4 is tightly attached to the matrix, in which the high temperature necessary for gluing the upper and lower films is constantly maintained during operation. Inside the matrix are vacuum (B), cooling (O) and neutral (H) sectors. In the vacuum sector, cells are molded on the bottom sheet and two films are thermally glued. In sector (O), by cooling or otherwise, the drum is cooled. In sector H, there is no vacuum or cooling. At this level, the lower film is heated.

 Behind the thermo-adhesive drum there is a mechanism 5 for unwinding the upper film, a cutting device 6, a feeder 7, a mechanism 8 for pressing channels and their thermo-gluing and a mechanism 9 for winding film wastes.

 The manufacture of packages on a device with a drum matrix is carried out as follows.

 When you turn on the drive device, the torque is transmitted to the drum matrix 3 and the mechanism 9 for winding film waste. From the unwinding mechanism 1, the lower film, passing through the heater 2, is heated and tightly applied to the cylindrical matrix 3. In the vacuum sector B, cells and channels connecting these cells are formed on the film. In this sector, using the thermo-adhesive drum 4, the matrix is welded to the lower molded film from the upper, which is wound from the unwinding unit 5. The films glued together form blocks of containers that enter the cutting device 6, where they are cut into individual sealed packages. Packages are fed to feeder 7 and filled with liquid product through its hose and tip, and then the cells are sealed by squeezing and welding the channels with the device 8. The film wastes are wound onto the film-winding mechanism 9.

 A device with matrices placed on the Maltese cross (Fig. 3) does not have significant differences from a device with constant matrices (Fig. 1). The only difference is that the place of matrix 3 (Fig. 1) is replaced by one of the matrices of the Maltese cross, which is in the position indicated by the number 1; and in place of the mechanism 5 of thermal gluing of two films, there is another of the matrices of the Maltese cross located in the position indicated by the number 3. On one of the matrices, the molded lower film is molded and cut (position 1 of FIG. 3), and on the opposite matrix (position 3 of FIG. . 3) simultaneously with the molding, two films are thermally glued.

 Molding packages on the matrices of the Maltese cross (see Fig. 3) is carried out as follows. From the unwinding unit, the lower film is heated on a heater (not shown in Fig. 3) and fed to one of the matrices of the Maltese cross located in position 1. On this matrix, cells are formed with channels connecting them, followed by cutting. The molded film on this matrix from position 1 is automatically moved counterclockwise to position 2, where it is cooled, and then fed to position 3. In this position, the upper film is applied to the molded and cooled film and glued together with the subsequent cutting of the upper film. Then the matrix with the finished packaging enters position 4. In this position, the packaging is blown out or removed in a secondary container.

Thus, in one cycle, after the Maltese cross rotates 90 ^° , the lower film is molded and cut at the same time (position 1), the molded film is cooled (position 2), the lower molded film is thermally glued with the upper and its subsequent clipping (position 3), and blow or removed finished packaging in a secondary container (position 4).
