Abstract

An apparatus for a machine for packing chickens with legs cut off at the joint into plastic bags, which machine is arranged at the lower end of a movement arm and is moved by means of the latter into two operating positions, to pick up the chickens by the joints of their legs cut off at the joint individually from a transport means and to insert the chickens into the plastic bags with subsequent pressing of the legs cut off at the joint onto the bodies to which they append, is characterised in that the apparatus consists of a single shaping part (3) which can be pivoted into two switch positions (8 or 9), in that the shaping part (3) is designed in such a way that it is suitable in one switch position (8) for picking the chickens up from the transport means and, once they have been inserted into the plastic bags, for compressing the legs and releasing the bones of the joint from their mounting device in the other switch position (9). <IMAGE>

Description

Device for a packaging machine from

Chicken with legless thighs in plastic bag The invention relates to an apparatus for a legless chicken wrapping machine in a plastic bag, which is arranged at the lower end of a movement arm and over this to the individual transfer of the chickens to the joint bones of the legless thigh from a means of transport and for inserting the chickens into the Plastic bags with subsequent pressing of the legless thighs against their bodies is moved in two positions.

It is already a device of this type; has been proposed. This proposed 'device consists of two transport forks for picking up the joint bones of the chickens, each of which is made up of two brackets. In these Transport forks reach the joint bones by overcoming a spring tension standing pawl. This pawl is required to keep the articular bones at the Press the legless thighs against the body and do not slip out of the fork. There is a bracket for each joint to loosen the joint bones from the transport forks laterally pivotable.

The disadvantage of this device is the great mechanical effort due to the various moving parts and the associated increased costs as well as the increased susceptibility to failure.

The invention has therefore set itself the task of the described Eliminate disadvantages.

This object is achieved according to the invention in that the device consists of a single, pivotable in two switching positions molded part that the molded part is designed so that it can be taken over in one switching position the chicken from the means of transport and, after inserting it into the plastic bag, in the other switch position to compress the thighs and to loosen the joint bones from its bracket is suitable.

In an expedient embodiment of the invention, there is the device in that the molded part is at least half-shell and around a horizontal bearing is pivotably mounted that the one end face of the half-shell molded part with two slots are provided to accommodate the joint bones of the chickens, and at the opposite end face an actuator is articulated, and that the half-shell molded part in the switch position to take over the chickens from the side, and is open at the bottom in the second switch position.

Because when the chicken was taken over from the means of transport, the half-shell If the molded part is open at the side, the joint bones can be inserted into the two slots slide in and are held there until the upsetting process of the chicken thighs begins.

At the start of the upsetting process, the half-shell molded part is also included the opening pivoted downwards so that the articular bones slide out of the slots must and during the upsetting process on the upper inside of the half-shell Support the molded part.

After the upsetting process has ended, the molded part can be released from slide the chicken up with the motion arm.

To aid the persistence of the compression molded chicken is expediently further proposed that an additional counter to the movement arm Spring tension acting hold-down device is provided, which is designed in such a way that that he is in use at the beginning of the pressing process of the legs against the chicken body got.

The invention is explained with reference to the illustrated embodiment.

In the figure, 1 denotes the movement arm, which has a controllable pneumatic cylinder 2 move vertically into its two end positions of use can be.

At the lower end of the movement arm 1, the molded part 3 is pivotable mounted around the pivot bearing 13, with the slots arranged on one end face 4 5 and the pneumatic cylinder 7 articulated on the other end face 6 as an actuator, arranged.

The switching position 8 of the molded part 3 is that for receiving the Chicken from the means of transport. The indicated switching position 9 shows the one for pressing and loosening the chicken. By pivoting the molded part 3 in switching position 9 is the yielding under spring tension by the cam lo Hold-down device 11 released and deviates according to the downward movement of the moving arm 1 back to the top. Before that, the hold-down device 11 still has the task of removing the chicken to be passed through the guide funnel 12 in a stretched manner. For upsetting and pressing the legless chicken thigh to the body of the chicken is where the molding is located 3 in the switching position 9, so that the joint bones are on the inside of the molded part 3 can support.

Under particularly extreme conditions it is possible that the joint bones Slip out of the slots 5 during the process of inserting the chicken into the bag.

To ensure a secure packaging process for these individual cases as well In addition, a spring 14 is to be guaranteed at the slots 5 intended, through which the thigh bones into the slots 5 in the manner of a snap or pulled out.

Claims (3)

Claims 1) Device for a chicken packing machine with legless thighs in plastic bags attached to the lower end of a movement arm is arranged and above this for taking over the chickens individually to the joint bones the legless thigh of a means of transport and for introducing the chickens into the plastic bag with subsequent pressing of the legless thighs on them Body is moved in two positions of use, characterized in that the One device that can be pivoted into two switching positions (8 and 9) Molded part (3) ~ consists that the molded part (3) is designed so that it is in the one Switching position (8) for taking over the chickens from the means of transport and, after the Insertion into the plastic bag, in the other switch position (9) to compress the thigh and is suitable for loosening the joint bones from their holder. 2) Device according to claim 1, characterized in that the molded part (3) at least half-shell and pivotable about a horizontal bearing (13) is stored that one end face (4) of the half-shell molded part (3) with two Slits (5) are provided to accommodate the joint bones of the chickens, and at the opposite end face (6) an actuator (7) is articulated, and that the half-shell molded part (3) in the switching position (8) for taking over the chickens laterally, and in the second switching position (9) is open downwards. 3) Device according to claim 1, characterized in that on the Movement arm (1) additionally a hold-down device (11) acting against spring tension is provided, which is designed so that it starts with the pressing process the thigh comes into use on the chicken body.
