"Device for opening and closing screw caps

for bottles "

Lately more and more tougher Fla see with screw caps Use, especially for fruit juice drinks and the like. When the bottles are transported back to the bottler, this is done by rubbing off the closures still present on the bottles are required, which is associated with a comparatively large expenditure of time is.

To mechanize this work, there is already a device has been proposed, which has two circumferential conveyor belts arranged one above the other, which once the bottle body, and on the other hand, press the bottle neck against a counter strip covered with a sponge. However, this known device has significant disadvantage that the closures are not released with certainty, especially not when they are strong are encrusted, which occurs very easily with sugary liquids, for example, and therefore disturbances in the subsequent ones Work steps, i.e. when rinsing the bottles, etc., are unavoidable are.

On the basis of this prior art, the invention is 1

the object of the invention is to create a device for opening and closing screw caps for bottles which j

is easy to manufacture and handle, and]

allows the locks to be loosened and turned off with certainty.

i light, and moreover a comparatively large j

Throughput. i

/ According to the invention this is achieved in that in one Frame a roller or the like. is rotatably mounted, which at a distance of one, the shape of the roller or the like. adapted jaw is encompassed, and above the roller or the like. a curved one Bar is attached, which one or more rotatable rollers or the like. assigned. The roller or the like. and this Adapted jaws form a guideway for the actual bottle body, while the bar above it and their associated rollers or the like. form a guideway for the bottle mouths. In this way it is achieved that the Bottles are guided exactly, on the one hand on the bottle body, where they are firmly clamped, and on the other hand on theirs Mouth, whereby od the like. The bottle body executes a Drviibewbewegung due to the rotational movement of the roller, and by the Muzzle adjacent bar is exerted a fixed rotational movement on the screw cap with the rollers assigned to it, so that this will be resolved with certainty.

The jaws are under the action of compression springs, which

702623822.10.70

support themselves in supports attached to the frame, so that a fixed clamping and thus inevitable rotation of the bottles, achieved by srix-d .. The strength of the springs is adjustable, so that the device can also be used with bottles of different diameters.

The rotatable rollers or the like are driven by means of a frame

the
bar, which is placed around a pulley, which sits aif a shaft which od through the drive shaft of the lower roller. The like. Extends. This embodiment is extremely space-saving. The rotary movement of the upper and lower rollers can be taken from a single drive source f> js by means of a gear.

At the end of the guide track for the bottle mouths, a discharge nozzle and a suction device are provided, so that the shutters are automatically transported away, and the now s \ open bottles to the further processing operation can be supplied. The device according to the invention itself is advantageously set up next to a conveyor belt, with the bottles being guided from the conveyor belt into the guideway of the device according to the invention by means of a scraper known per se.

An embodiment of the invention is explained in more detail with reference to the drawing, which shows:

With i the frame is referred to, which is downwards further extends for installation next to the conveyor belt 2. In the frame 1, the roller 3 is mounted, which on its surface "Gummier-1 is uxid is located on a hollow shaft 4, which in the direction of rotation indicated by arrow 5 can be driven. The roller 3 is loaded with an intermediate space 6 of around a jaw 7, which is also rubberized on the surface facing the roller 3. The jaw 7 is under the Action of compression springs 8, which are mounted in the frame 1 Support supports 9. The roller 3 and its associated jaw 7 form the guide track for the. Bottle body 10. By the rotation of the roller 3, the bottle body is also in. Rotation, as indicated by arrow 11 ben is.

] Above the roller 3 is in the frame 1, a curved bar

j 12 arranged, which two rotatable rollers I3 are assigned.

The two rollers 13 are driven by means of a belt 14, which for this purpose is placed around the pulleys 15, 16, of which the pulley ± 5 is located on the shaft 16 which passes through the hollow shaft k of the roller 3. The shaft l6 can be driven in the direction of rotation indicated by the arrow 17, which results in a rotation for the rollers 13 according to the arrow l8.

The arrangement is such that the roller 3 in. .binding with the jaw 7 assigned to it clamps the bottle body 10, while the two rollers I3 with their associated curved bar 12 clamp the bottle mouth.

To Passing through the guide track 6, the bottles 10 reach the area of the blow-off nozzle 19, which blows off the loosened closure, which is then conveyed away by means of a suction device 20. Now the bottle is placed back on the conveyor belt 2 and continues its original path to the further processing stages away.
