Description of the invention

The utility model relates to the food industry, in particular to machines for aseptically filling 2 multi-layer bags with an inner stopper, used in the production of fruit and vegetable semi-finished products in the form of juices, concentrated juices and pureed products.

The closest technical solution is the machine of the company "Teiga ZiagAzeri EShipd Maspipe" for aseptic filling of multi-layered bags of the "Star-Acept" type with an internal stopper | see Advertising prospectus of "Temna Rak" company.

The machine has a frame that is mounted on four screw supports, a lever lifting mechanism, strain gauges and a column on which a traverse, a compressed air preparation system and a power supply cabinet are installed on the frame. A roller conveyor is installed on the tensometric scales.

A manipulation unit and control and control panels for this unit, as well as product supply and discharge pipelines are fixed on the traverse. The manipulation unit has two separate devices: one of which has 72 mechanisms for pinching the plug and removing it from the nozzle of an empty bag when uncorking it and installing it in the nozzle when closing a bag filled with product, the second mechanism is for attaching the nozzle to a special sterilization chamber by grabbing it with two levers and pressing, a system for supplying steam to the sterilization chamber for sterilizing the end of the stopper and nozzle before filling the bag with product and for short-term supply of steam to the unfilled part of the bag after it is filled, a chamber for the product, valves and piping for steam and condensate removal.

All mechanisms are driven by pneumocylinders, eight of which are installed on the machine.

The plug clamping mechanism is made in the form of a cylinder, inside which there are four teeth that move in the grooves due to the conical end of the rod fixed to the end of the pneumatic cylinder rod when the bag plug is pinched, and are insulated inside the cylinder when the bag is separated from the plug by means of springs. shsh

The mechanism for opening and closing the stopper has a rod mounted on an axis with the possibility of horizontal movement, and on which the mechanism for pinching the stopper of the bag is installed. The rod is driven by a pneumatic cylinder through a rod and a lever. In addition, the mechanism has a bumper, which is fixed on two rods with a drive from two pneumatic cylinders. All these mechanisms are installed in a box-type housing, which is fixed with Z at the end of the traverse. Gee)

The mechanism for attaching the nozzle of the bag to the sterilization chamber has two pneumatic cylinders, which are installed with the possibility of rotation around a vertical axis and on the rods of which two grabbers are attached, which have cutouts - in the form of half rings, as well as a pneumatic cylinder, which, with the help of levers, rotates the previous two pneumatic cylinders with grippers around vertical axes. 3o The sterilization chamber is made in the form of a thick square plate with a round hole on the axis and has a system of mutually perpendicular channels, in two of which there are spool valves, which are mixed along the channels due to the supply of compressed steam to these channels from one or the other side.

Seven valves are connected to the channels with the help of nozzles, which control the supply of steam and the removal of condensate. The sterilization chamber is hermetically connected to the product supply chamber, which has a valve with Z 50 actuated by a pneumatic cylinder and to which the product supply and discharge pipelines are attached. In order to ensure the tightness of the chamber, the connection of the rod of the pneumatic cylinder and the valve rod is made of

With" the use of a special conical bellows.

All the specified mechanisms, the sterilization chamber, the product supply chamber, and the product supply and discharge pipelines are installed in a box-type housing, which is fixed at the end of the crossbar. Control panels for controlling and controlling machine mechanisms are installed above these housings. o This technical solution is chosen as a prototype.

- focus on full original production of all component parts of the machine, including general technical products such as pneumatic cylinders; - frequent stoppages in work due to the fact that the teeth of the cork clamping mechanism are not always drowned by springs, and restoring their efficiency requires considerable work on disassembling and assembling the cork clamping mechanism.

The basis of the useful model is the task of improving the machine for aseptic filling of multi-layer bags, in which, by modifying the design of the lifting mechanism, the mechanism for pinching the cork when it is removed from the bag nozzle, the mechanism for fixing the bag nozzle on the sterilization chamber, and/or equipping it with additional mechanisms , which makes it possible to achieve a reduction in the mass and dimensions of the machine, simplification of the design of the mechanisms, continuity of the process of feeding the product into the bag, to ensure the simplification of the design of the machine as a whole, increase its productivity and efficiency, as well as the reliability of the technological process and the quality of the finished product.

The task is solved in a machine for aseptic filling of multi-layer bags, which includes /5 btanin, a lifting mechanism, a weighing device, a column with a traverse on which a sterilization chamber is placed, a manipulation unit, which includes a mechanism for pinching the cork when it is removed from the bag nozzle, made in the form of a rod with a rod placed inside it, inside which is installed a gripping element driven by a pneumatic cylinder, a mechanism for opening and closing the cork, a mechanism for attaching the nozzle of the bag to the sterilization chamber, a control panel, an electrical supply cabinet, a system of 2o Preparation of compressed air, inlet and outlet nozzles product, steam and condensate outlet nozzles, according to the useful model, the machine additionally contains a lifting mechanism installed on the traverse, a weighing device, a sterilization chamber, a manipulation unit, a control panel, and the lifting mechanism is made in the form of a lifting carriage mounted on guides x column with a chain partially balanced drive installed in the upper part of the column, the engaging element is made in the form of a collet with petals, inside which there is a rod with the possibility of longitudinal movement, and a ring is fixed at the end of the collet, while a finger is fixed in the middle part of the rod, which moves the sleeve, which is installed on the outside of the collet, and the mechanism for attaching the nozzle of the bag to the sterilization chamber is made in the form of a frame attached to the rod of the pneumatic cylinder, which consists of two half-frames, and has the ability to move in the guides with the help of rods "E zo New in the useful model, that is declared, is the presence of the following features: - the machine additionally contains: x, - lifting mechanism, "- - weighing device, - sterilization chamber, c - manipulation unit, c - control panel, - the lifting mechanism is made in the form of a lifting carriage mounted on column guides with chain partially balanced drive; - the arresting element is made in the form of a collet with petals, inside which there is a rod with the possibility of "longitudinal movement, and a ring is fixed at the end of the collet, while in the middle part of the rod, a finger is fixed with c, which moves the sleeve, which is installed on the outside of the collet; - the mechanism for attaching the nozzle of the bag to the sterilization chamber is made in the form of a frame attached;" to the rod of the pneumatic cylinder, which consists of two half-frames and has the ability to move in the guides with the help of rods.

The overall technical result is achieved by a set of essential features and is explained as follows.

GI Equipping the machine with an additional lifting mechanism, a weighing device with a platform, a sterilization chamber, a manipulation unit, and a control panel made it possible to carry out the process of filling bags under the condition of direct product supply, because when auxiliary operations are performed with one bag, the second one is filled and vice versa. It also made it possible to double the productivity of the machine.

Implementation of a mechanism for lifting containers with bags in the form of a carriage that moves along the racks of the column with

Me. counterbalance, allowed to significantly reduce energy costs for lifting and lowering due to the fact that the load on the drive is only half of the weight of the product in the bag. Exclusion from the machine of the roller conveyor with the replacement of its support platforms, on which the pallet with the container and the bag is installed, significantly reduced the load on the scales and improved the tare-product ratio, which, in turn, made it possible to use scales with a lower load capacity and increase weighing accuracy . Thus, several advantages have been obtained: simplification of the design, reduction of the weight of the machine, elimination of the requirement for equipment of scales with arrester, with the possibility of using serial commercial scales, reduction of dimensions, reduction of load on the lifting mechanism, saving of energy resources.

The new design of the cork clamping mechanism provides forced opening of the collet and its closing from one standard pneumatic cylinder with the help of one rod, which increased the reliability of the mechanism, simplified the design of the mechanism, and reduced its weight.

Changing the design of the mechanism for securing the bag nozzle to the sterilization chamber made it possible to change the algorithm of performing operations and thus shorten the period of performing auxiliary operations due to the combination of some operations according to the period of their performance. 65 In addition, the product supply chamber with a valve of individual design of the saddle type was excluded from the design of the manipulation unit, and this complex and heavy element was replaced by a serial rotary valve with a serial drive pneumatic cylinder.

Fig. 5 - view A on the frame for securing the bag nozzle;

Fig. 6 is a diagram of the supply of steam to the sterilization chamber and the removal of condensate and steam from the sterilization chamber. 70 The machine for aseptic filling of multi-layer bags includes a frame 1, a column 2, two traverses 3, two manipulation units 4 with two control panels 5, two carriages 6, on the platforms of which two electronic scales are placed 8, two lifting mechanisms 9 of carriages b, a power supply cabinet 10, compressed air preparation system 11.

Bed 1 is a frame structure and has two protrusions 12 on both sides, on which a 7/5 pallet is installed with a container inside which there is a bag.

Column 2 is made in the form of a metal structure, which has guides 7 for carriages 6, for example, in the form of four racks that act as supports and guides at the same time.

The manipulation units 4 have a support 13 and two blocks of mechanisms 14 and 15. The block of mechanisms 14 includes: a sleeve 16, which is attached with bolts to the vertical wall of the support 13 and in the middle of which a rod 17 is installed with the possibility of linear movement with the help of a pneumatic cylinder 18, which fixed on the sleeve 16 with the help of four ties 19 and a platform 20. The set of these parts forms a mechanism for uncorking and closing the bag (removing the cork from the nozzle and installing it in the nozzle after filling the bag with the product).

In the middle of the rod 17, a collet 21 is placed and fixed with a part 22. Along the axis of the collet 21, a rod 23 passes, which has the ability to move longitudinally, and at the end of which a ring 24 is fixed with the possibility of movement along the rod, which is intended to open the petals of the collet 21 when the rod 23 is moved back . In addition, a finger 25 is passed through the rod 23 t, which moves the sleeve 26, the latter compresses the petals of the collet 21 when the rod 23 is moved forward. The movement of the traction 23 is carried out by the pneumatic cylinder 27, which is fixed on the rod 17.

All these parts form a mechanism for pinching the plug when it is removed from the bag nozzle and releasing the plug from the bag after sealing at the end of its filling operation.

The mechanism unit 15 includes: a frame 28, consisting of two half-frames 29 and 30, one of which 29 serves as a nozzle support, and the other 30 as a retainer. The half-frame 29 is moved up and down in the "- guides of the half-frame 29 with the help of the lever 31 and the rod 32. The frame 28 with the help of four rods is attached to the rod of the pneumatic cylinder 33, which is fixed on the sterilization chamber 34. c

Together, these parts form a mechanism for securing the nozzle of the bag on the sterilization chamber 34. c

The sterilization chamber 34 is made in the form of a thick plate with a cylindrical hole in the middle and channels for steam supply and steam and condensate discharge. Steam is supplied to the chamber 34 through the steam line 35 through the Zb valve, and it is removed through the pipeline through the valve 37, and the condensate through the pipeline through the condensate trap 38.

Directly to the sterilization chamber 34 is hermetically attached the product supply valve 39 3 tv) with a pneumatic drive 40 and to the last pipeline 41 through which the sterile product is pumped.

The machine for aseptic filling of multi-layer bags works as follows: electric loader or ;" using a stacker, the operator installs a pallet with a container on the protrusions 12 of the bed 1. The operator removes the protective cap from the nozzle of the bag and inserts the nozzle into the frame 28, after which he presses the "start" button on the control panel.

GI Next, the following machine operation algorithm is performed: - the pneumatic cylinder 33 presses the end of the bag nozzle to the sterilization chamber 34 so that a hermetic space is formed, which consists of the cylindrical surface of the sterilization chamber 34, the end of the bag plug, - the outer surface of the product supply valve and supply channels and steam and condensate outlet blocked by 5p valves 36, 37 and condensate trap 38;

Me, - valve 36 opens the supply of steam to the sterilization chamber and the process of sterilization of all parts of the specified hermetic space begins, the condensate formed at the same time is removed through the condensate trap without breaking the tightness.

Sterilization takes place for a given period of time and is controlled by the appropriate time relay. - simultaneously with the sterilization process, the pneumatic cylinder 13 moves the rod 17 forward, while the end of the rod enters behind the plug into its inner cavity; c - the pneumatic cylinder 27 moves the rod 23, the ring 24 and the sleeve 26 in a backward stroke.

At the same time, the petals with the teeth of the collet 21 diverge, come out of the grooves in the rod 17 and pinch the bag plug by a special edge, which is for these purposes on the back end of the plug; in - after the end of the sterilization period, the relay sends a command to open valve 39 for product supply and to uncork the bag.

The pneumatic cylinder 40 of the product supply valve 39 opens the valve, the supply valve 36 closes the steam supply, and the pneumatic cylinder 18 moves the stem 17 back and thus uncorks the bag; - the process of filling the bag with the product begins; 65 - in the process of filling the bag with the product, the operator periodically lifts the carriage 6 up using the lifting mechanism 9;

- after filling the bag, according to the signal from the electronic scales 8, the product supply valve 39 is closed; - after closing the product supply valve, a command is given to open valves 36 and 37, and to close the bag plug.

Due to the difference in the timing of the valves 36 and 37 and the pneumatic cylinder 18, a short-term steam purge of the sterilization chamber 34 and the unfilled part of the bag occurs, after which the valves 36 and 37 are closed; - the pneumatic cylinder 27 moves the rod 23 in a forward motion and the collet 21 is compressed, the teeth of which 7/0 sink into the rod 17 and release the bag plug. - the pneumatic cylinder 18 moves the rod 17 out of the plug cavity to the extreme position in a backward stroke; - the pneumatic cylinder 33 moves the bag nozzle away from the sterilization chamber 34, which allows the operator to remove the bag nozzle from the frame 28, the operator lifts the lever 31 up, while the thrust 32 lifts the ZO half-frame up and allows the nozzle to be removed from the half-frame 29; - the operator puts a protective cover on the nozzle and, using the lifting mechanism 9, lowers the carriage 6 to the lowest position, while the pallet remains on the protrusions of the bed; - an electric forklift or a stacker removes a pallet with a filled bag in the container and replaces it with a pallet with an empty bag in the container.

The work on the second half of the machine is carried out exactly according to this algorithm, only the period of execution of operations is shifted so that the process of filling bags is carried out continuously.

The design of all component parts of the machine is made in such a way that it allows you to remove them from the machine separately from everything else. All this makes it possible to carry out repair work in stationary conditions and only those component parts that need it, as well as to carry out interchanges of the corresponding component parts without stopping the operation of the machine.

The declared machine is manufactured in the experimental production of DNDPKI "Konservpromkompleks". t
