The invention relates to a device for separating conical bottle caps a stack of capsules plugged together for transport with a gripping tool that is used for Detachment of the foremost capsule from the next capsule of the stack grips them sideways.

The supply is located in devices or machines for closing bottles or the like on conical caps, mostly plugged into one another in a kind of capsule magazine; the capsules must be removed one after the other and put on each bottle. This process comes across to great technical difficulties, which means that even today in most filling plants, even if these are fully automated, capsules are pushed over the bottles by hand.

A number of proposals have already been made to mechanize this process. For example, it is proposed for capsules that are provided with a passage opening at the bottom been that an air tube is passed through the bottoms of the capsules of the stack, which through Inlet openings in the jacket air between the bottom of the last and the bottom of the penultimate Capsule blows and at the same time closes the passage opening in the bottom of the last capsule, causing it The capsule is lifted from the stack and transported on while the penultimate capsule is held and is pressed against the stack.

However, this method can only be used if the capsules have a passage opening in the bottom exhibit. But now it is particularly desirable for bottle caps that the bottom is on the outside forms a smooth surface in order to be able to attach a lettering or an image that refers to the content of the Advertise the bottle.

The difficulty in isolating capsules without this passage opening was that the nested Capsers tend to be not just individually, but in pairs or even in groups of three to peel off the stack. Attempts have also been made with gripping tools that remove the last capsule Grip from the capsule shell as lightly and gently as possible, removing the gripping parts with cushions Rubber or the like. Are provided. However, it turned out that the gripping tool was too weak and to gently grasp the outer capsules when, as is often the case, they are compressed into one another are and sit tightly together, slide off without taking a capsule with you, but that as soon as the pressure to attack is increased somewhat, more than one capsule is taken.

It is already a device for separating cardboard containers and for transporting them on Known container. A guide is used to hold a stack of containers in their lower Part with shoulders or depressions. On the side of the outlet end of the guide is one on both Pivoting levers provided with claws are arranged at the ends. Located at a distance below the guide a vertically displaceable plate, which is articulated with grippers. Of the Pivoting levers and the plate with the grippers are on a carrier plate that is moved vertically by means of a lifting rod assembled. In the lower position of the lifting rod, the lower claw of the pivot lever is below swiveled the container stack. When the lifting rod is raised, the plate hits the bottom of the lowest container, while the upper claw of the pivot lever engages the upper part of the penultimate container is brought. When the lifting rod continues to move upwards, the stack of containers pushes the plate down against the action of a normally open spring holding the grippers. This pivots the grippers inward until they engage the recesses of the bottom container. The grippers snap into the container recesses so that the plate pressed down and the grippers kept closed. If the 'lifting rod is then lowered, the bottom container is taken along until the gripper is released again when the rod is pressed be opened. ■

This known device is only in connection Can be used with relatively stiff cardboard containers equipped with indentations.

Bottle caps have no depressions corresponding to the known depressions. Such depressions would make the capsules more expensive in an undesirable manner and the rest of the decorative effect of the Capsules affect. But they are a prerequisite for using the known device. If the grippers were not able to lock into such depressions, the grippers would move at the beginning the downward movement of the lifting rod open again immediately; so the foremost container could cannot be detached from the stack of containers. Since bottle caps are generally made from very weak Material, e.g. B. thin aluminum foil, the capsules were also under the push-down the plate and the pivoting of the gripper against the action of the spring required Force to be crushed. At least the stack of capsules would be compressed so much that the Coat of the foremost capsule in the area of the depressions, if such were present at the Lowering the lifting rod would be torn open by the grippers.

Devices for separating bottle caps with gripping rings are also known, but they alone also does not guarantee a perfect detachment of the paper cups. In addition to the Fingers, the known device therefore has a rubber stamp on the bottom of the foremost Container pressed and for the purpose of loosening the container at a certain angle about its longitudinal axis is rotated. The known arrangement can just as little as the device described above can be used for separating bottle caps, as the rubber stamp is pressed on the bottle caps would be destroyed or at least pressed so firmly against the following capsules that detachment would be prevented.

The invention is based on the object, specifically the problem of separating bottle capsules to solve in a simple manner and to avoid the difficulties outlined above.

The invention consists essentially in that the gripping tool one or more against the Stack axis has radially movable claws under positive guidance, which the foremost bottle cap pushes back and the gripped bottle cap all the more is isolated more securely. The tool does not slide off.

A contact is preferably provided, by means of which the movement of the gripping tool in the direction to the capsule stack stopped at a predetermined point and the radial movement of the gripping tools is initiated. This contact can work mechanically or electrically and is useful attached to the gripping tool and immediately conducts the radial when it comes into contact with the capsule base Movement of the claws, at the same time the movement of the gripping tool towards the capsule is stopped will.

The point where the movement of the gripping tool is stopped can be movable. Advantageously the radial movement of the claws is also adjustable. Through these two settings the device according to the invention can be adapted to the various capsules which, for. B. in size, in the conicity of the jacket, their material differ from each other, be adapted.

According to the invention, each detached capsule becomes a certain amount by means of the gripping tool and the claws Distance moved away from the stack, whereupon the claws loosened in the radial direction and the Capsule is released for further transport.

Further features, advantages and possible applications of the invention are shown in the schematic

ίο held representations of exemplary embodiments as well as the following description.

The nested capsules are fed to the gripping tool 2 by a conveying device (not shown). The gripping tool 2 can be moved in the direction of arrow A and has claws 3 which can be moved in the direction of arrow B. Preferably three claws 3 are used, and the movement of the claws takes place radially. However, it is also possible to use two or only one claw, in the latter case the bottom end of the capsule is supported on a smooth surface opposite the claw. The starting position of the claws is denoted by 3 α (Fig. 1). From here, the gripper tool is moved in the direction of arrow A, to an unillustrated switch in contact with the bottom 1 α of the first capsule contact is and causes the movement of the gripping tool is stopped with the claws towards the Kapsem out immediately. The claws are now in the 3 ft position. The claws are then moved radially in the direction of the first capsule 1 as indicated by arrow B. After this movement of the claws, the extent of which is adjustable and is governed by the respective type of capsules has ended c in the 3-position, the gripping tool is again moved backwards in the direction of arrow C (F i g. 2), the claws take the first capsule with you. When the claws move inwards, the next capsule has been pushed away somewhat at the same time as a result of the indentation formed by the claws, whereby the separation of the gripped capsule 1 is facilitated. A retaining lip 4 ensures that the now first capsule is held in the stack, while the claws in position 3 d let go of the capsule that has been carried along and move in the direction of arrow D back into position 3 α . The process repeats and the claws move as shown in FIG. 3 shows again in the position 3 b.
