Description

German Patent Office, Munich 21.03.1989 Machine z ^|T m moving and packing of grids

The invention relates to a machine for packing and packaging goods, in particular for packing bottles, cans and the like in rows into packaging containers, boxes, cartons and the like, consisting of a gripper head with gripper devices guided therein for grasping the goods to be packed and a device for pivoting the gripper heads from the receiving position to the delivery position.

Machines of this type are used in particular in the packaging industry for handling bulk goods. The machines are used in particular in the beverage industry for handling and packing bottles or groups of bottles in containers such as boxes or similar. For this purpose, the bottles, which are brought in individually or in multiple lanes, are put together on a collection table in several rows next to each other and one behind the other and are grasped by gripper heads with gripper devices arranged on them and placed in the outer box. The incoming bottles are, as is well known, equipped with labels or other advertising media which are randomly aligned in all possible directions during the incoming flow. In particular, when using containers with viewing openings, the advertising effectiveness of the applied labels is practically limited by the random alignment of the relevant front sides.

without success, so that especially in the case of beer crates and the like, extra large cardboard or paper labels are inserted between the outer rows of bottles and the corresponding viewing windows. Special measures are required for this. In addition, the additional labels represent a significant environmental burden and also require additional effort during the unpacking process when returning the empty bottles.

In this context, it has already become known that the goods, bottles or similar in question can be run through additional machines after they have been placed in the relevant transport container or box, which rotate the bottles with their labels on the outer edge in such a way that they are clearly visible in the recesses or viewing windows of the boxes, thus increasing the advertising effectiveness and eliminating the need for additional inserted labels. The disadvantage here is that after the bottles have been transferred to the relevant containers, another machine unit and additional space is required for precise alignment (DE-OS 37 28 291).

The invention now has the task of ensuring an exact and repeatable positioning of the goods to be packed and stored during the required

To be able to carry out Umeet* operations&bgr;, whereby the goods

assigned labels or other advertising media in the

Area of viewing windows or recesses of the used Shipping containers should be visibly aligned.

Additional equipment that is required separately in the packaging flow to align the goods should be dispensed with.

This task is solved in a machine for moving and packing goods in an independent configuration by the features of the patent claims.

In a particularly advantageous manner, the accumulated rows of bottles and/or bottle groups are viewed and aligned accordingly immediately after delivery, so that at least the outer rows of a packaging group with the labels attached face outwards and can then be placed in the corresponding shipping containers. The specially applied labels or other advertising media are then aligned exactly with the relevant viewing windows of the packaging containers and can fully develop their advertising effect. Additional intermediate layers or labels that are inserted between the outer edge of a packaging group and the packaging container can be used.

The alignment itself takes place without delaying the transfer process and using the gripper devices that are required for transfer anyway. The additional effort required to align the labels is therefore minimal and easy to handle.

In the following, the invention is explained in more detail using embodiments shown in the drawings. The drawing shows

Fig. 1 is a general view of an example

used packaging machine and Fig. 2 a corresponding design of the gripper device.

The example shows a typical packing machine used in the beverage industry in particular. This can be equipped accordingly and designed and used in a different form and for other branches. The machine described here for transferring and packing bottles and containers consists of a feed and collection table 1, 2, a transfer device 3 and an associated conveyor 4, 5 for the containers 6. On the feed table 1, the containers 7 run in several rows next to each other to the end of the collection table 2, on which they are then piled up in a plurality of rows 8 next to and behind each other and held ready for the transfer process.

The actual transfer device 9 moves above the collection table and has a large number of gripper heads 10 next to one another and, with a correspondingly higher performance, one behind the other. These gripper heads 10 can be equipped with any grippers, suction grippers, gripper bells, gripper devices, so that different types of goods such as bottles and the like can be gripped. The actual conveyor 4, 5 for the boxes or cartons or containers 6 is located in front of the collection table 2. During the transfer process, the transfer device 9 first grips a complete group of containers from the front end of the collection table 2 and lifts them along a specific track 11 in order to deposit them in the containers 6 fed in front of the collection table 2. As soon as the gripper devices 13 have gripped a corresponding group of bottles 16, these are rotated about their vertical axis into a predeterminable position, so that at least the outer labels 14 face outwards and are clearly visible through the corresponding viewing windows 15 of the packaging container 6. The position of the randomly gripped bottles 16 shown is determined by sensors 17 arranged on the gripper heads 13', which then influence correspondingly controllable motors 18, which ensure the required alignment of the labels 14 or other advertising media in the direction of the viewing windows 15. For this purpose, at least

the outer grippers 13' of the gripper group formed from the individual grippers for determining the position of the bottles picked up 5 sensors 17 with which the relevant label 14 and/or the advertising medium can be determined by motor rotation and brought into a corresponding external viewing position. This takes place without any time delay during the transfer process, which is required anyway. Each gripper device 13 and/or each gripper device 13 forming the outer area of a gripper device group is mounted in the actual gripper head so as to be rotatable about its vertical axis and is designed with a rotating device 19 which can be activated accordingly after the bottles 16 to be transferred have been picked up and can be positioned by sensors 17 determining the advertising medium and/or the like. The sensor carrier itself is arranged on the gripper heads and, according to the embodiment shown in Fig. 2, extends with the sensor 17 into the area of the markings, labels 14 and the like. The arrangement is selected so that the sensor carrier 20 extends into the space between the bottles in the complete packaging group and the sensor 17 expediently points in the direction of later viewing openings 15 of the packaging containers 6 to be assigned. This can then initially determine the randomly aligned labels 14 and thereby cause a corresponding rotation of the gripper 13' by the motor 18 _; for example, it is conceivable that the gripper devices forming the edge rows each have a common

A sensor strip is assigned to the packaging group, which can be moved into the entire packaging group during the transfer process and can be moved out of it again before the actual depositing process, so that the packing process itself is not hindered by additional devices. A twisting device has proven to be particularly useful, which is designed as a servomotor 18 that can be rotated in both directions, the twisting position being determined by timers that can be activated and set via sensors 17. Firstly, an edge of the existing labels 14 or the like is determined, whereupon the servomotor 18 is activated again using timers or tilting sensors and carries out the desired alignment of the labels 14 in the direction of the viewing opening 15 of the shipping container 6 in question.

In Fig. 1, a further feed line 21 is provided for bottles pre-packaged in groups 22. The groups 22 are grasped by special grippers and, if desired, can also be placed in a container provided for this purpose in an appropriately aligned manner.

In Fig. 1, 12 denotes scanning elements that check the completeness of the surface rows on the collection table 2.
