of containers

The invention relates to a device for turning and palletizing or depalletizing containers, in particular of cylindrical metal beer kegs whose nozzle, is arranged on the top surface of the barrel, from the upside down position in which such Barrels are filled or cleaned by 180 ° in the upright position in which such barrels are tapped.

For some time now, the wooden barrels of beer barrels have been increasingly replaced by metal barrels. The metal barrels, which have a simple cylindrical shape are easier to manufacture than the bulbous wooden barrels made from a variety of wooden staves, easier to clean and also easier to use. The valve is located in these metal kegs known as KEG kegs on the top of the barrel and not as with the wooden

barrel in the middle of the bulbous outer surface. These KEG barrels are always under a certain pressure, even if they do not contain any beer, so that when they are upside down they are fermented from below * through the valve and filled with beer. barrels in a brewery first in the inverted position Urid ~ have to be reversed by 180 ° ^v after filling with beer because these drums have in their natural position to the pin with the valve for 'above.

For turning the cleaned metal kegs filled with beer devices of the type mentioned have already been proposed in which the cylindrical Metal drums, however, can only be rotated individually by 180 ° and where palletizing is carried out in one of the Turning device separate second device is carried out. By erecting individual barrels and by the further transport of these individual erected barrels to the palletizer are known in these However, devices only run the clock speeds a lot small. In addition, these known devices require the separate arrangement of the turning device and the palletizer takes up a lot of space.

The present invention is therefore based on the object of providing a device of the type mentioned at the beginning create that only take up a comparatively small amount of space has and with which a much higher cycle speed is possible, especially around cylindrical metal drums from the inverted position by 180 ° to the upright To turn the position around and to put it down on pallets and on the pallets in the same device to move out of the device.

the barrels with high cycle speeds is possible.

i Special advantages of the device according to the invention! also exist in the compact structure of the system, so that its space requirement is very small, and in that it is very ro- | bust is and works practically maintenance-free. j

The transport device is preferably arranged at a higher level than the feed device that is used for
Transport device is arranged vertically, and the
Turning means may be arranged laterally next to the transport device and the feed device by the arrangement of the transport device over the forward, pushing means, it is very easily possible, the trans - ¹ port device aligned vertically to the feed means so that the delivered on the transport device inverted barrels in rows next to and
can be placed one behind the other on a pallet, with the upside-down barrels with the turning device
be brought into the upright position. This arrangement results in the possibility of a very compact construction of the device according to the invention and a trouble-free operation of the same.

The feed device can lay-on technology for the support
of the pallets and endless belts running parallel to one another with crossbars for advancing the pallets, the crossbars being spaced apart from one another
can have, which is slightly larger than the extent of the pallets in the feed direction of the feed device.
With such a feed device, it is very much
easily possible from a stack of pallets under which

According to the invention, this object is achieved by a Transport device for transporting the inverted container into the device, a feed device for the step-by-step feed of pallets in and through the device, and through a turning device for Remove at least one inverted container from the transport device and for placing the container turned by 180 ° into the upright position a pallet, the turning device having at least two lateral gripping arms for gripping the lateral surface a container, a drive motor to drive at least one pinion and at least one archway ' has shaped guide rail which is provided with a toothing corresponding to the pinion and a leg the guide rail in the vicinity of the transport device for the container and the second leg of the Guide rail in the vicinity of the feed device for the pallets ends.

The upside-down, for example, cylindrical kegs filled with beer are automatically transported into the device, wherein Stops can be provided in order to position the barrels just right in front of the turning device. Simultaneously With this transport of the barrels, the pallets stacked next to the device according to the invention are removed moved one after the other with the feed device in and through the device according to the invention. This feed movement is a step-by-step movement that is controlled, for example, by light barriers. The gradual control of the pallets is carried out so that at least two from one barrel or from two or rows of three barrels can be arranged close together on a pallet. Since the step-by-step pallet feed and the turning process can be carried out at the same time, results with the according to the invention

the feed device runs through it, in each case the lowermost one resting on the guide rails To drive the pallet into the device according to the invention, at the turning device with at least one barrel, but preferably at the same time with several upright to load standing barrels and complete them then gradually move loaded pallets out of the device according to the invention. Through this, that the distances between the crossbars are slightly larger than the extent of the pallets in the direction of advance the individual pallets at any time without tilting, on the support rails on and with their rear on the crossbeam, so that the pallets can be advanced step by step through the device according to the invention can be.

The turning device can y.woi arch-shaped guide rails which are arranged laterally above the feed device, on each guide rail at least one pinion engages in the teeth and on the guide rail on the opposite one of the teeth Side is at least one roller connected to the pinion and the pinions of the two guide rails with Shafts are connected with a centrally located Drive motor are driven. With the rollers, the pinions are always and in every position of the turning device securely pressed against the teeth of the guide rail, so that the pinion is always safely in the teeth engage the guide rail. Due to the shafts connecting the pinions, there is a mechanical extreme stable structure of the device according to the invention, see above that tilting of the pinion on the two guide rails is reliably avoided.

Λ-

Preferably, two pinions can engage in the toothing of each guide rail and two threatening rollers connected to the pinions can rest on the side of the guide rope opposite the toothing. By arranging two pinions and two rollers that hold the pinions in engagement with the teeth, the guiding properties of the turning device have been further improved and, in any case, secure engagement of the pinions in the teeth of the guide rail is ensured.

In one embodiment of the invention, the gripping arms each have a diameter of three barrels corresponding span, with the middle of the barrels to be turned against the two outer barrels to Turning device is arranged offset and the gripping arms partially grip around the two outer barrels. By this displacement of the middle fascia against the Both side barrels result in a .secure holder of all three barrels, so that three kegs Turned 180 "in a single operation, and burned out standing on 1: can be placed on a pallet.

For precise definition of the networking of the middle barrel against the two outer barrels on the side, which are in the Size is around 10-15 mm, the middle barrel on one. Stop against the turning device.

With the device according to the invention it is therefore possible to grab several upside-down cylindrical barrels at the same time, to turn them by 180 ° by means of the turning device and to stand upright on a pallet moving step by step through the device. Included In a first step, three KEG barrels are dispensed simultaneously on the pallet. Afterward this pallet with the feed rate] η r i c: hl unq
