Abstract

The invention relates to a device for sorting out defective candy packages. The purpose is to produce quality packs without subsequent manual sorting process. The object of the invention is to detect faulty packages and to remove them from the quality packs. This is achieved in that the acceptance gripper are pivotally mounted on one side of the effective range on Abnahmerad, which are associated coaxially with respect to pivotally mounted waves sensing lever, each of which is connected to one of the formschlüssess affiliated acceptance gripper, a lever arm, the pressure pin on a cam lever, the mounted on a pivotally mounted, parallel to the waves of the picking gripper and the waves of the sensing lever shaft, rests and the cam roller of the cam lever is connected to the cam plate mounted on the axis in operative connection and the lever levers are arranged on the feeler levers whose cam rollers on the cam track of a cam assigned to them and rest on the lever arms pawls are mounted, which are in operative connection with a, mounted on the shaft locking lever.

Description

-2- 231 569

The storage of the waves of the picking gripper and the sensing lever and their functional elements are arranged within a housing. The acceptance grippers have a shape profile on the gripping surfaces. This makes it possible to remove defective packages from the stream of quality packs and thus automatically perform the further production process in good quality.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing show:

Fig. 1: a half section through the Abnahmerad

2 shows a section of the wire Fig. 1 "

3 shows a section B of FIG. 1

At the periphery of the take-off wheel 1 are in the recess of the housing 2, the area of action of the take-off wheel 1 outside the housing 2, picking gripper 3; 3 'respectively at the free ends of the shafts 4; 4 'fixed and coaxial with the free ends of the shafts 5; 5'the feeler lever 6; 6 '. The acceptance gripper 3; 3 'are connected to a tension spring 7, are about the tooth segments 8; 8 'in conjunction and have on the gripping surfaces a mold profile 9; 9 'up. The feeler 6; 6 'have tension springs 10; 10'auf, which are attached to the housing 2. Within the housing 2 is located on a respective Abnahmeabreifer 3; 3 ', a lever arm 11 which is provided with a pressure pin 12, which rests on the cam lever 13. The cam lever 13 are mounted on the shafts 14, which parallel to the WeIIeVi 4; 4 'and 5; 5 'are arranged. The cam rollers 15 of the cam lever 13 rest on the cam track of the cam 16, which is fixedly connected to the axis 17. Each feeler 6; 6 'is with lever arms 18; 18'versehen. At the lever arms 18; 18 'are cam rollers 19; 19 'mounted, wherein the cam roller 19 rests on the curved path of the cam 20 and the cam roller 19' on the curved path of the cam 21. The cams 20; 21 are fixedly connected to the axis 17. At the lever arms 18 are still the pawls 22 and the lever arms 18 ', the pawls 23 are fixed, each of which a locking lever 24 which is mounted on the shafts 14, is assigned

 The operation of the device is the following:

The wrapping wheel of a candy wrapping machine not shown by the picking gripper 3; 3 'of the pick-up wheel 1 in already proposed manner acquired candy. B by detecting the drill points of the wrapping, are on further transport by rotation of the take-off wheel 1 about the axis 17 and thus by running the cam rollers 19; 19 'of the lever arms 18; 18 'on the cam tracks of the cams 20; 21 by a slight closing movement of the sensing lever 6 produced therewith; 6 'sampled. The scan consists of the on the feeler levers 6; 6'schräg formed pressure surface in a slight lift-off movement. In a package that meets the required quality, lifting the candy B is within the packaging container by the sensing lever 6; 6 'not possible and the on the lever arms 18; 18 'attached pawls 22; 23, which can also act independently of each other, do not sit in front of the locking lever 24. Thus, the cam roller 15 continues to act on the cam track of the cam disc 16 by transferring the position of the locking lever 24 via the track 14 to the cam lever 13. This process requires that by the design of the cam track of the cam 16, the acceptance gripper 3; 3 'at the point where the quality packages leave the machine. Is now between the acceptance grippers 3; 3 'is a defective package (eg, package wrap gapes up, package wrapper is turned over or no package wrapper exists), then the feeler levers 6; 6 'or one of the sensing levers 6; 6'the candy, which loosely in the Pack'mittelhülle, or without packaging wrapper in the mold section 9; 9 'is loose, lift slightly. Thus, the sensing lever 6; 6 'closed further than in a quality pack and the pawls 22; 23 or one of the pawls 22; 23 can sit above or in front of the locking lever 24. The lever arms 18; 18 'thus remain in the locked position and thus also, via the shaft 14, the cam lever 13 with cam roller 15. Since the cam roller 15 no longer rests on the cam track of the cam 16 by the lock and thereby does not run on the cam track, the Opening of the picking gripper 3; 3 'not at the point of delivery of the quality pack "but continues to the waste container for packages with packaging errors.
