Abstract

This invention relates to a sterilization technique, in particular, to devices for sterilizing quadrilateral cardboard containers for liquids before filling, filling and closing. The purpose of the invention is to improve the quality of sterilization. Sterilization is carried out using a spraying nozzle 21 for impregnating the inner surface of the cardboard blank after removing it from the magazine 1, in which the blanks are folded, and when removed from the magazine by suction cups 17, they are opened to form a tubular shape. The tubular shaped blanks are moved on the mandrels 5 of the rotating cylindrical body 4 in the operation of closing the containers, after which the containers are filled with liquid and their upper part is closed. 7 il. g SU) FIG. one

Description

one

This invention relates to a sterilization technique, in particular, to devices for sterilizing quadrilateral cardboard containers for liquids before filling, filling and closing.

The aim of the invention is to improve the quality of sterilization (this increases the shelf life of the product in containers).

FIG. 1 schematically shows a device for sterilizing, filling and closing quadrangular cardboard containers, side view, vertical section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the sequence of operations carried out with the container during its movement

go agent under pressure. The conveyor 15 is reinforced so that its upper branch and mandrel 5, which is in working position, are located at the same level, and the nozzle 21 is located coaxially with this mandrel. The device is equipped with a device 24 for removing the container with a closed bottom from the mandrel, driven

0 in reciprocating motion and equipped with a suction cup 25.

The device works as follows.

Covered with a thermoplastic non-processing tanna cardboard blank 2 (Fig. 4) is removed using vacuum suction pads 17 from the store 1, and the quadrangular blank 2 is opened to form a pipe

through the device; in fig. 4 - complex 2o (Fig. 5), which is supplied to the potential container, is ready for loading into the device; in fig. 5 - capacity is empty; in fig. 6 - capacity after closing its bottom; in fig. 7 - the tank is full and closed.

1 The device contains a store 1 for

accumulating quadrilateral blanks

2 when folded, mounted on a horizontal shaft 3, a cylindrical body 4 with mandrels 5 radially disposed thereon for accommodating cardboard containers, obtained first from the blanks 2, and devices 6-9 for hermetically closing the bottom of the containers, device 10 for filling containers and 11 -14 to close the upper side of the tank: ty. Under the preform store 1, there is a conveyor 15 with a protruding finger 16 for moving the tubular preform 2. A means of suction is mounted above the conveyor 15 to extract the folded preforms 2 from the store 1 and to give them a tubular shape, Medium 1 va made in the form of suction pads 17 fixed on the gate element 18, installed with a 90 °

can turn on

to capture the workpiece, open it and move it. At the location of the slide element 18, an arcuate guide 19 is installed, and the magazine 1 is provided with snaps 20 for cutting off the subsequent billet. Directly above the conveyor 15, from the side of the opposite mandrel, is mounted the dispatching nozzle 21 connected by means of the generator 22 and the pipeline 23 to the supply source of the sterilizing unit 15 and is moved by it to one of the mandrels 5. The nozzle 21 is placed coaxially with this mandrel and the tubular billet located on it and spreads a sterilizing spray agent on the inner side of the tubular blank, which also gets onto the mandrel, swirls and additionally covers the inner surface of the tubular blank. I

Then, when the cylindrical body 4 with mandrels 5 rotates, the mandrel with the finished workpiece is fed to the fixture 6 for pre-bending the edges of the bottom of the blank 2, after which the mandrel with the finished blank is fed to the fixture 7 to warm the bottom part of the blank, and then to the fixture 8

40 for folding and squeezing the bottom of the workpiece, followed by feeding it to the device 9 for additional squeezing of the bottom. Capacity with a closed bottom comes to the device for.

45 removing it from the mandrel, where the container is captured by the vacuum 1-suction cup 25, is pulled out of the mandrel and drained to the conveyor 26, above which is placed a device 11 for pre-bending the upper edges of the container, a device 10 for filling the container with a predetermined volume of product, for example juice , a device 12 for folding the upper edges of the pro-container 55, a device 13 for heating the thermoplastic container's edge closing, a device 14 for finally closing the upper part of the container under the action of pressure and cool the. When the container is moved by the conveyor 26, the above operations are performed on it. After which the prepared container is discharged to the discharge station.

When the preform is sterilized with an agent such as chlorine dioxide, heat is supplied to it from the preheating device 7.

When used to sterilize hydrogen peroxide, a heating device may be inserted between the device 11 for pre-bending the upper edges of the vessel and the device 10 for filling the vessel, while removing the remaining hydrogen peroxide before filling the vessel with the product.
