Description

This invention relates to a centering mechanism for capping rotary column designed for closing with nailing or screw caps of containers with various shapes and without necks < This invention will find applicatio in the food processing industry. &chgmnmd of t&e invention

A rotary column, which includes a reducer group mo nted to the main drive shaft of the column via bearings , is known from patent BG 111339, At the upper end of the main drive shaft, a upper guiding platform is placed, to and under which_., symmetrically to its axis, screwing devices are located,

A main hearing body is fastened to the main drive shaft _> which is under the upper guiding platform and above the reducer group. Under the main hearing body, there is a cam mounted to the main drive shaft, centered to an irremovable flange. The flange itself is attached to a support platform, A main heating is mounted to the upper part of the flange, which separates the rotating member of the column from the non- rotating one.

The reducer group with the electric motor, the main gear wheel, and the cam arc located under the support platform. The screwing devices are centered both to the main bearing body and to the tipper guiding platform.. Control of each screwing device is executed by the cam. through a drive roller, which is mounted at the. upper end of the screwing device and placed in a notch made in the cam.

A cap feeding platform a d an inlet, device are located in a particular sector under the screwing devices. Underneath this, is located a support platform for containers, which is irremovafoly bound to the main bearing body. Centering carriers are provided for positioning of the containers, along the periphery where there are holders with lateral lower and upper anil -rotation members, Irremovab!y attached above the support platform, Carrying and guiding of the containers can be done simultaneously by their neck and also by tlieir bottoms,

The know rotary column is not suitable for capping of containers, for example of parallelepiped shape , and particularly with a neck, which is positioned asymmetrically to the central axis of the bottle. The known rotar column is not suitable for capping of containers, which do not have neck, as the guiding of containers in that case is done by their neck, and bottoms,

Sniiffigfy of the inwi tloi

One aim of the invention is to design a centering mechanism for rotary column that can be used for capping containers with, various shapes, without necks, with nailing or screw caps, and with different opening locations to the container's centra! axis.

This aim is achieved by a centering mechanism for a rotary column for capping containers with nailing or screw caps, where one or more centering mechanisms are set circumferentially and symmetrically to the rotary column's mai drive shaft.

Each centering mechanism is comprised of a. support platform, on which there is a container, which is to he capped. Centrally below and to the siipport. platform, through releasafole connection, is rigidly connected a centering axis mounted to the guiding member via hearing. In the guiding member and in the centering axis, there is a perpendicular opening, where there s a bearing axis located, irremovably bound to the guiding member. At one end of the bearing axis, there is a drive bearing mounted, rested in a notch made in the cam, which is aligned and kremovahly bound to the main hearing body of the rotary column, A movable platform, is irremovably bound to the guiding member, to which there are bound two holders that pass through openings made in the support platform. The openings in the support platform correspond to the shape of the holders. The holders are changeable, and their shape depends on the shape of the container being capped. The support platform of the centering mechanism is changeable, as its shape and size depends on the shape and size of the container being capped.

The advantages of the invented centering mechanism for the rotary column for capping containers are that it allows a very accurate and reliable positioning under the capping heads of containers of various shapes and without necks.

Brief descri ti n of the dt a istgs

The invention is illustrated by the accompanying drawings, where:

~ Fig, 1 is an axonometrie view of the rotary column for capping containers ;

~ Fig, 2 is a. longit udinal section view of the rotary column from Fig. 1, without the 'upper part;

^■· Fig, 3 is a. longitudinal section view of a centering mechanism. est; Eli^d d serifstl is o invention

The rotary column (Figs. 1 and 2} is composed of a main drive shaft 1 to the lower part where there is fixed a main gear wheel 2, which is driven by a motor (not shown i the accompanying figures) < By means of this motor, trie rotary- capping column is driven into rotation around its lifting axis 25. irreniovahly to the upper end of the main driving shaft 1 , a upper guiding platform 5 is mounted. (Fig. 1), to which circularly and symmetrically to its axis, there are arranged screwing (nailing) devices 4, as when the main drive shaft 1 starts rotating, all the screwing {nailing} devices start to rotate around axis 4,

Simultaneously, the screwing (nailing) devices 4 for caps are driven as to perform a reciprocating motion, controlled by the upper cam 6, and simultaneously, the screwing devices 4 perform rotational motions around its own axis, driven by a motor reducer group 24, which is located in the upper part of the rotarv column.

The main hearing body 8 is fastened to the main drive shaft 1 , above the main, platform 3 and under the upper guiding platform 5 by means of screws (Fig, 2).

To the main drive shaft Ϊ , above the main bearing body 8, a cam is mounted. 9 (Fig. 2), which is centered and fastened to the main bearing body 8 by fastener's ?,

Centering mechanisms 1 1 (shown, in. Fig. 3} are mounted to the rotary capping column, circularly and symmetrically of the main drive shaft: 1. Each, one of the centering mechanisms 1 1 is comprised of a support platform 16, on which there is the container 10, which is to be capped. Under the support platform 16, by means of releasab!e connection 12, a centering axis 13 is attached irremovably, which is mounted at each end via. bearing bushes 14 to the guiding member 15. The guiding member 15 and the centering axis 13 are placed freely in an opening in an Intermediate platform 18 (Fig, 2), as the centering axis 13 in its lower end is attached irremovabl to a lower guiding platform 1 ,

Between the platforms - the intermediate IS arid th lower guiding platform 18 - are placed support columns, which connect irremovably both platforms 18 and 19.

In the space between platforms 18 and 19, perpendicular to the guiding member 15 and to the centering axis 13, is an opening in which a bearing axis 20 is located, fixed irremovably to the guiding member 15, At one end of the bearing axis 20 is mounted a drive bearing 21, set in a notch of the cam 9_;! which is fixed to the stationary part of the main hearing bod 8 of the rotary colum <

In the upper part, of the guiding member 15, a movable platform 22 is mounted to which there are fixed, holders 23 passing through openings made on the support platform 16. The openings of the support platform 16 correspond in shape to the profile of the holders 23, which, are changeable depending on the shape of the container to be capped 10, In this case, the holders 23 are connected, to the movable platform. 22 by a bolt connection.

The support platform 6 is also changeable, and its shape and size depend on the shape and. size of the container heing capped 10. According to the described embodiment, each of the containers 10 intended for capping, is of parallelepiped shape, as the holders 23 are also of parallelepiped shape and are four in number.

The main drive shaft 1 is mounted to the main bearing body 8 via bearings .17.

Operating principle of the centering mechanism:

By rotati g the main gear wheel 2, the main drive shaft starts rotating 1, and along with it, the centering mechanisms 1 attached to platforms IS and 19.

The control of the centering mechanisms 1 1 is earned out by the cam 9, in which there is a notch, which includes the bearings 21 of the guiding member IS, When the rotary column starts rotating, the centering mechanisms .1 1 start rotating around the central axis 25 of the rotary column, and as the drive bearing 21 moves along the notch of the cam 9, the guiding member 15 of the centering mechanism 11 moves in a vertical direction. Thus by the help of the holders 23, the container 10 is fixed and centered, While centering, the opening of the container 10 stands concentrically with the axis of the screw (nailing) mechanisms 4 (Fig. 1), and after the cap is screwed or nailed to the container 10, the holders 15 are pulled vertically down, by the bearings 21 , moving through the cam notch 9 and releasing the container 10.
