Abstract

By a device (2) for continuous weighing and preferably arranged in connection with a turning wheel (4) for an endless conveyor being provided with suspension shackles or forks (8) for broilers or parts thereof, or comprising weighing containers, as the device (2) comprises a number of lifting means (18), which are adapted to lift free and support suspension shackles, forks (8) or weighing containers, and therein suspended broilers, broiler parts or weighing members along a partial section preferably around the turning wheel (4), and which are adapted to co-operate with an electronic weighing cell, each of said lifting means (18) comprises an electronic weighing cell (24), which in a suitable manner is connected with belonging weighing and registration equipment.

Description

Device for continuous weighing
The present invention relates to a device for continuous weighing, and of the type de¬ scribed in the introductory part of claim 1.
For instance in connection with slaughtering and cut up of poultry, for instance broilers, the broilers are transported between respective treatment stations by means of hanging conveyors with suspension shackles, in which the broilers normally are suspended in the legs.
In order to sort the broilers after weight either to form larger groups of broilers with uniform weight or to form uniform portions of broilers or parts of broilers it is in con¬ nection with hanging conveyor known, that special suspension shackles for the broilers or said broiler parts in a partial section of a particular hanging conveyor - most often in connection with a turning wheel - are lifted free from the hanging conveyor and tempo¬ rarily supported on carrier means, which thereafter in turn briefly affect a common weighing device, for instance an electronic weighing cell. Known weighing devices of this type has a complicated construction and a limited capacity; and they have also shown to be less precise.
The invention has for its purpose to provide a device of the mentioned type for more general continuous weighing, and which by simple provisions makes it possible to obtain an increased capacity and an improved accuracy.
The device according to the invention is distinctive in that each of said lifting means comprises an electronic weighing cell, which in a suitable manner is connected with be- longing weighing and registration equipment. By means of simple provisions a weigh¬ ing device is hereby obtained, which may operate with considerably larger transition speed, that is having increased capacity and at the same time showing improved accuracy. The increased capacity is rather simply obtained by the fact that more lifting means with each its weighing cell may be activated at the same time. The fact, that weighing engagement is maintained for quite a long time, results in an improved average weighing accuracy at the same time.
Preferably the device according to the invention is such provided, that said partial section has such a length, that 6 to 12 lifting means may be activated at the same time, and that a steering rail for lifting means is stretching 180° to 225° along the circumfe¬ rence of the turning wheel.
The invention is explained in more detail in the following with reference to the drawing, in which :-
Fig. 1 shows a sketch of endless hanging conveyor with a turning wheel with a weighing device according to the invention, while
Fig. 2 shows an embodiment of a weighing device according to the invention, for in¬ stance cf. line II-II in Fig. 1.
The weighing device 2 shown is arranged in connection with a turning wheel of an endless hanging conveyor 6 being provided with particular, two-parted suspension shackles or forks 8 having an upper eye part 10 and a lower fork part 12 with a horizontal carrier part 14.
Under the turning wheel 4 a number of lifting means 18 with outer hook parts 20 are mounted on a common shaft 16, which hook parts 20 in relation to a basis part 22 of the lifting means 18 are supported by each its electronic weighing cell 24. The basis parts 22 are displaceable on vertical sliding rods 26 stretching between the periphery of horizontal carrier discs 28. Opposite the weighing cells 24 the basis parts 22 are provided with a steering wheel 30 co-operating with an arched, stationary steering rail 32 in such a manner, that the lifting means 18 - as the carrier discs 28 are rotated synchronously with the turning wheel 4 - are displaced upwards on the sliding rods 26, when the steering wheel 30 is lead upwards by engagment towards the topside of the steering rail 32, and are displaced downwards, when the steering wheel 30 again is allowed to be lead downwards - by the end of the steering rail 32.
The lifting means 18 are positioned along the turning wheel 4 with same mutual angle distance as that of the suspension shackles 8 of the hanging conveyor, so that the outer hook parts 20 of the lifting means interact between the lower fork parts 12 and the re¬ spective suspension shackles 8 - and under the horizontal carrier parts 14.
in the left side of Fig. 2 is shown, how the weighing engagement is established by the fact that the lower fork parts 12 are lifted free from the eye part 10, when the hook part 20 together with the lifting means 18 is displaced upwards by engagement between steering wheel 30 and steering rail 32. That is that active weighing engagement is estab¬ lished between the fork part 12 and the electronic weighing cell 24, as long as the - belonging steering wheel 30 is rolling along the topside of the steering rail 32.
In the right side of Fig. 2 is shown, how the weighing engagement between the hook part 20 and the fork part 12 stops, when the belonging steering wheel 30 is allowed to be lead downwards, when the steering rail 32 ends.

Claims

CLAIMS:
1. A device for continuous weighing and preferably arranged in connection with a turning wheel for an endless conveyor being provided with suspension shackles or forks for broilers or parts thereof, or comprising weighing containers, as the device compri¬ ses a number of lifting means, which are adapted to lift free and support suspension shackles, forks or weighing containers, and therein suspended broilers, broiler parts or weighing members along a partial section preferably around the turning wheel, and which are adated to co-operate with an electronic weighing cell, characterized in that each of said lifting means comprises an electronic weighing cell, which in a suitable manner is connected with belonging weighing and registration equipment.
2. A device according to claim ^characterized in that said partial section has such a length, that 6 to 12 lifting means may be activated at the same time, and that a steering rail for lifting means is stretching 180° to 225° along the circumference of the turning wheel.
