Description

MA SYSTEM I TRANSFERRED LI N HA PRODUCTION PAIN

[0001] The present invention relates to a production line transfer system capable of collecting chicken thighs from one or two anterior (knot) lines and hanging from a single posterior (knot) line. This equipment can be used in poultry slaughterhouses and / or refrigeration industries, making the transfer between air carriers (knots) intelligently without the need for human intervention.

[0002] Production line can be understood as a form of series production, where various workers and / or machines, specializing in various specific and repetitive functions, working sequentially, arrive at a semi-finished or finished product.

Air carriers (knots) are responsible for moving the product between the workstations of the production line, leading the animal (chicken) hanging on hooks by the production line.

[0004] The system described in this patent will generally be used in poultry production lines and normally positioned between the cutting and boning stages, in which position only the chicken thighs and thighs are hung, as the rest are already in place. was processed in the previous steps. Normally after the cutting step the knot goes to the packaging step, but in some cases the product may need to go to the boning line.

Currently, the thread change is done manually, that is, between the cutting and packing steps there is a device that drops the product from the nomad, and it slides through ducts or transported by treadmills, placing it on a workbench where employees manually hang and align the product in a second area leading to the boning process, whether automatic or manual.

To meet the above need, the present invention has been developed which aims to automatically perform this task which is currently done manually by removing the thighs from the knot (s), positioning and hanging on the knot that will lead right up to the boners, and right thigh gear and left thigh gear are needed. With the aid of computation, the production line transfer system communicates with other machines present on the production line through its electronic control, allowing the equipment to perform functions / tasks to optimize the process without human intervention, as for example. For example, if any subsequent machine has a malfunction or is under maintenance, the present system may cause the hook intended for this machine to be empty as it would not remove it because it is out of operation, which causes rework. In addition, it is possible to communicate with machines from previous stages, allowing the present invention to stop collecting specific products that pass through the conveyor and are destined to other machines or with the help of a scale. The electronic control can select the products to be collected. by weight range.

The selection guide (3), lung (4) and driving guide (6) components are equipped with a rail made from joining two profiles by connecting plates so that between these profiles remains a gap with sufficient spacing so that the thigh bone can travel the length between this gap so that the joint located at its end is no larger than this gap, thereby ensuring that the thigh will travel all the way through the equipment without being detached from the rail even when positioned vertically. Along the track, more specifically in the region of the guideway (6) and the lung (4) this track comprises a conveyor belt responsible for leading the thighs to the separation device (7).

At the very beginning of the process, there is a selection guide (2) which is positioned so that its initial end is perfectly aligned on the underside of the anterior knot hooks (1 and 2) so that when passing through this, the thigh fits into the selection guide (3) which soon thereafter has a curve to the outside of the knot causing the thigh to detach from the hook and then it runs the rail to the other sectors of this equipment. The selection guide (3) comprises a deactivation system which contains a pneumatic or hydraulic piston controlled by the electronic control which can bypass the retraction of certain positions as directed. If the system needs to ignore a certain product of the nomad, the piston is actuated by angularly displacing the selection guide (3) and thus not removing the thigh from the previous nomadic hook. To retract the thighs, the piston should return to the normal position and thus aligning the selection guide (3) with the nozzle hooks. Then the thighs move to the driving guide (6). The driving guide (6) is responsible for leading the thighs to the separation device (7) and the excess products are accumulated along the rail forming a lung (4), which is simply formed by a certain amount. being able to hold some spare parts, absorb a possible momentary higher speed from the front conveyors (1 and 2) and keep the rear conveyor (5) free of failures. When the lung (4) reaches its reserve capacity limit, that is, occupying the entire driving guide (6), the monitoring sensors communicate the situation to the electronic control, which automatically interrupts the collection of products from (s). ) previous node (s), which targets another processing line or temporary storage for manual processing. This lung (4) also assists in product failures provided by the anterior node (1) by ensuring that the posterior node (5) works at its full capacity.

In the driving guide (6) there is an inclined track section, such that the thigh rotates from vertical to horizontal position, which remains attached by the driving guide (6) and pulled A conveyor belt, which forms a support and positions them through the action of gravity at their center of mass, making all thighs in a standard position.

After the lung (4) and alignment the thighs pass through the separation device (7) which causes the thighs to separate, remaining in the ideal position and spacing for use in the posterior node (5) through a system. of helicoid such that the thighs are uniquely spaced according to your pass. The separation device (7) is synchronized with the dosing system (8) through a set of pulleys and belts.

[0012] The last step is the dosing system (8), which performs the function of selecting, positioning and distributing the products in the rear node (5) as directed by the electronic control. The dosing system (8) comprises a set of two discs which are driven by a servomotor / gearmotor and synchronized together with the separator device helicoid (7) through a set of pulleys and belts.

The thighs are separated unitarily from the lung (4) by the separation device (7), providing a thigh at each position of the disc, which is captured by the first disc of the dosing system (8) due to its geometry forming a tooth species for each available position; after approximately 180 ° rotation the two discs meet and at this moment the second disc captures the thighs in a similar way as the previous one, which in turn when performing a 180 ° rotation will be tangentially aligned with the posterior knot (5) and then the electronic control will drastically reduce the speed of the servomotor / gear motor while waiting for the rear knot hook (5) to be perfectly aligned with the disc tooth; At this time the mechanical arm installed on the inner side of the second disc through a piston will push the thigh up to the hook of the rear knot (5) thus completing the cycle. At this stage, the system by communicating with later machines and their logical processing determines which positions should be filled and which positions should remain empty so there is no waste and / or rework in subsequent steps.

Under the thigh path in the driving guide (6), separation device (7) and dosing system (8), a splash and drip pick-up rail is installed which, in addition to maintaining the environment sanitized protect the thighs that may fall during the process, as a protective grid is installed on it.

In cases where there are two anterior knots (1 and 2), the thighs are retracted alternately between anterior knot 1 (1) and anterior knot 2 (2) forming a single line on the guide rail. conduction (6), forming a lung (4) in its extension. Then the thighs pass through a separation device (7) composed of a helicoid which has the function of keeping the thighs with a certain spacing that is in sync with the dosing system (8), which is composed of perfectly electronically synchronized discs. with the rear knot (5) for hanging.

The two-node removal process provides flexibility on the production line so that the anterior nodes (1 and 2) can rotate independently from each other and also from the posterior node (5). In this way if the nomad lines (1 and 2) feed two or more transfer points at the same time, and a transfer point needs to stop production, the product hanging from the nomad is automatically redistributed between the other transfer points. This is possible thanks to fully independent operation between these devices, ie there is no synchronization or dependency between them. Another application example: when there are two nomad lines with individual capacity less than the deboning line capacity, all product is removed from one nomad line being considered as main, clearing it and collecting from a second line. The amount of product left to supply the deboning line.

[0017] The production line transfer system is managed by an electronic control which, in addition to comprising electronic modules, is equipped with several sensors that monitor all steps, as well as obtaining information directly from the anterior (1 and 2), posterior ( 5), lung accumulation (4) and later machines in order to detect its velocities, operating status and also empty spaces; With these data, the electronic control determines optimal values for parameters such as: optimal angular speed of the dosing system discs (8), deactivation system management and driving guide belt speed (6).
