DK149226B - PROCEDURE AND EQUIPMENT FOR FULLY AUTOMATIC FILLING OF A FOLDING BOX WITH CONTAINERS FROM ONE END SIDE - Google Patents

Description

The invention relates to a method for fully automatic filling of a folding box with containers from one end side and of the nature specified in the preamble of claim 1, and a plant of the kind specified in the preamble of claim 2 for carrying out the method.

Such a method is known from US patent 29 68 898. The grouping of the bottles used is carried out in a transfer station by transporting one longitudinal conveyor to another conveyor by means of a transverse movement. This grouping is very expensive and does not allow for continuous operation as the bottles will accumulate before the grouping station.

A continuous grouping is described in DE Publication 21 10 198 and. can be seen especially in FIG. 2. The longitudinally adjacent containers advancing on a transport device are braked by retention joints running in between each group of containers.

Thus, when filling cartons of three length rows with 25 four bottles in each, the retention joints move in between every four bottles. The grouping is thus already done at the first run-in of the detention joints. At the end of the braking distance, the restraint joints move away from the range of operation of the containers, so that the four bottles so far braked by that retention joint are accelerated. Thus, the acceleration does not occur at a particular location of the transport route, but rather in an area comprising four bottles longitudinally. The four bottles remain standing close to each other under acceleration and are all braked as a group. Therefore, there is no relative displacement between the bottles. The grouped containers are taken with an accompanying gripper and packed in the prepared cartons.

A disadvantage of the known filling method is that both the first braking distances and the removal devices or their transport speeds must be changed by switching from one pack size to another.

The object of the present invention is to provide a packing method of the aforementioned kind, in which switching from one pack size to another, where appropriate, from one container type to another can be done in a substantially simpler way.

This is achieved according to the invention by proceeding as set forth in the characterizing part of claim 1.

In the method according to the invention, the bottles which are brought close together are braked individually at a certain point of the transport section. At another point of the transport route, the braked containers are accelerated individually and in succession, so that a certain, always equal distance between the containers is obtained in the longitudinal direction. Up to this time 30, the containers have not yet been grouped. The grouping is according to the invention first by braking the front containers of each longitudinal row at the same time, so that the subsequent containers run against the front containers. When a certain number of containers have run against the front containers, the subsequent front containers are braked in each longitudinal direction before they can run against the front front containers. The grouping thus occurs only at the braking after the acceleration. The main advantage of the grouping method according to the invention is that the grouping is possible first in the take-off device. Therefore, when switching from one pack size to another, the take-off device 10 must be changed since the previous braking occurs completely independently of the pack size. Thus, the method of the invention inserts a universal braking, thus avoiding the conversion of the first braking device required in the known processes by changing the pack size.

A plant of the kind specified in the preamble of claim 2 for carrying out the method may suitably be designed as specified in the characterizing part of claim 2.

In this way, a simple construction ensures a safe execution of the method.

Conveniently, the plant may also be configured as claimed in claim 3.

A constructive particularly elegant solution is obtained when the system is designed as specified in claim 4. The transport device can e.g. consist of orbiting chains.

Conveniently, the plant is also designed as claimed in claim 5.

The length conveyors have a constant flow rate which is above the flow rate of the spacers, e.g. may be attached to an endless circumferential band, chain or similar means.

5 The upper part of this belt or chain is then located between the length conveyors and at the same height as these. Spacers moving from the lower part to the upper part dive between each two containers, extending laterally over the associated 10 longitudinal conveyors. From that moment, the containers are passed between the lugs. The containers are thereby forced on the smaller speed of the orbital lugs, while the length conveyors, the surface of which is smooth, continue at a constant speed. After the delay elongation thus produced, the length of which is determined by the length of the upper part of the longitudinal conveyors of the spacer or the corresponding means, the container which, viewed in transport direction, becomes first in each longitudinal row. , released by spacing the spacers down again. After severing the connection between the spacer and container, the transport speed of the container is again determined by the length conveyor to which it belongs. Thus, the container released from the spacer has an acceleration. This gives a distance from the container that follows longitudinally.

"As this process occurs simultaneously at each of the adjacent container length rows, 30 arising from the distance conveyors which are spaced apart from each other, are arranged between the so-called transverse rows. The slider is also arranged on an endless orbital conveying device which is conveniently adjacent to the longitudinal conveyors.This conveying device is designed so that the guided separators travel further in the conveyor length direction, however at a lower speed than the container-longitudinal conveyors. Thus, the higher-speed container transverse rows run one after the other against the guided separator and engage one another, after the desired number of transverse rows have been summed up to one wrapping unit, a different separator is introduced. in container litter mmm, and towards this the subsequent transitions run in the same way. The front wrapping unit 15 of a transverse slider can be slid into a front opening box. Here, too, to ensure a continuous course, it is advantageous when the transverse sliders together with the separator slides forward in longitudinal transport direction, while the boxes to be filled on the opposite side of the longitudinal conveyors are transported forward synchronously with the separator sliders and transverse sliders in transport direction. .

The invention is further explained with reference to the drawing, in which an embodiment of the system is shown schematically.

The system shown consists of several spaced length conveyors 1 for each row of containers 2, the width or diameter of which is greater than the width of the longitudinal conveyors 1. The longitudinal conveyors 1 change into a splitting device for forming packing units. This device consists of endless circumferential spacers 3 attached to each one orbital chain 4 or similar means on both sides of a longitudinal conveyor 1. The upper part of each chain 4 lies between the longitudinal conveyors 1 and at the same height as these, so that that the spacers 5 3 stand up. above the conveying plane formed by the longitudinal conveyors 1 * The spacers 3, which are round in cross-section and upwards slightly tapered, form between themselves such free length spacers that when bending from the lower part to the upper part of the chain 4, they appear between two containers. 2. The transport speed of the spacers 3 is lower than the speed of the longitudinal conveyors 1, whose transport direction is indicated by an arrow 5.

The longitudinal conveyors 1 extend over the operating range of the chains 4 spaced by spacer 3 for an acceleration section. Next to the length conveyors 1 opposite to the direction of rotation of the chains 4 is arranged an endless circulating conveyor 20. 6, which may also consist of e.g. chains and similar bodies. In this device, several separator sliders 7 are arranged and between them a transverse slider 8. The sliders and transverse sliders rotate in the direction of an arrow 9 and can further be moved across the longitudinal conveyors 1 and over these respectively between and against the containers 2. The rotational speed of the conveyor device 6 is lower than the speed of the length conveyors 1. 1

Opposite the transport device 6, on the other side of each longitudinal conveyor 1, is a transport device not shown for folding boxes 10 opened on one end side, which is transported forward in the direction of an arrow 11 and is thus arranged on their transport device not shown. there is always a folding box 10 with an open end side opposite a transverse slider 8. The transport speed of the folding boxes 10 in the direction of an arrow 11 corresponds to the transport speed of the transport device 6 after the arrow 9.

Plant works as follows:

Containers 2 are transported forwardly in multiple 10 adjacent longitudinal rows at a constant speed in the direction of arrow 5, with each container length row 12 being a longitudinal conveyor 1. The transport speed is higher than the orbital speed of the chains 4 and thus the transport speed of the the spacers 3 which are attached to these chains. From the moment the spacers 3 coming from below appear between every two containers 2, the containers are passed between the spacers 3, that is, braked in their transport speed relative to the longitudinal conveyors 1. Between each longitudinal conveyor. 1 and each container 2 thus a relative movement occurs. The container 2, which in the transport direction, stands in the first place in each longitudinal row 12, is released when the spacers 25 3 are again bent downwards. Because of the disconnected connection therefrom between the spacer 3 and the container 2, the last one will again be moved with the transport speed of the longitudinal conveyor 1, so it is accelerated. As this course occurs simultaneously 30 in all longitudinal rows 12, there is thereby obtained behind the braking distance formed by the circumferential chains 4, container crossfire T3 spaced apart on the longitudinal conveyors 1.

<8 149226 1 In order to then separate suitable wrapping units of the containers thus transported forward, a separator 7 in the direction of an arrow 14 is inserted between two container transverse rows 13 transversely of the trans-5 port direction 5. Since this separator 7 also runs further in the general conveying direction, but at a slower speed than the longitudinal conveyors 1, the container rows 13, which are advanced forward at a higher speed, will run against the introduced separator 7 and engage one another.

After the desired number of container cross rows 13 is summed to a wrapping unit during cancellation of the previously provided longitudinal distance, a second separator slide 7 is introduced into the container stream. In the illustrated example of the plant, the wrapping unit, which exists between two separator sliders 7, comprises three transverse rows 13. The wrapping unit thus separated is then shot into a transverse slider 8 which is inserted in the direction of an arrow 15 across the conveying direction 20 5. a folding box 10, which is also moved forward synchronously in the direction of an arrow 11. Subsequently, the transverse slides 8 and the separator slides 7 are retracted again in the direction of an arrow 16.
