The present report describes a machine used for realizing the automated process of poultry packaging, entire, or in parts, such as chicken, turkey, chester, among others. Such machine carries out the whole process of packaging, including the poultry position within the packaging, its closing and sealing.
initially, the poultries packaging, such as chickens, entire, or its parts, was carried out manually by operators. This condition showed numerous drawbacks, such as low productivity, operator dependency, lesions due to repetitive strain of the operator, non-conformities, lack of operation regularity etc.
The American patent document U.S. Pat. No. 4,141,194, published on February 1979 revealed some improvements regarding the packaging fully manual of chickens, or parts of chickens; this document describes a machine which provides means for grasping the chicken along legs, a hopper for directing the chicken to an opening packaging, prepared at the lower part, and the packaging must be automatically positioned to receive chicken, and its previous closing. This document indicates a solution very primitive, but very important for the packaging fully manual previously known.
Another document must be mentioned, the German document DE2758289, published on June 1979, that also shows a dispositive for packing poultries and a configuration which provides better centralization of the poultry.
Another latest solution, already known, is described on the Brazilian document MU8700798-3 deposited on July 2007, in this provision, the chicken is overthrown of the production line directly on adequate funnel in the position to be packed, falling directly within the respective plastic packaging that shall be open, pressured by airstream, given that this packaging contains a perforated supporting tab, that gets stuck into the output nozzle of such funnel, in order to burst this perforation when the chicken falls of the upper part of the machine into the packaging, emphasizing it of the packaging refill, roller type, receiving an adequate seal, given that the machine is ready for receiving a new chicken that falls through the funnel.
On the basis of the referred documents, it shall be noticed that already exists a solution for packing poultries automatically, gaining productivity, through automatic feed packaging machine; improving subsequently the packaging stage through centralization and better position of the chicken within the packaging, as revealed by the German document; and on the Brazilian document, it appears that all machine improvements whose configuration provides set of hoppers that already allows to receive the chicken of the line production and directing it until the packaging remains open with the help of airstream.
The latest and technically feasible solution hitherto known in the current technical status is described on the Brazilian patent document MU8900365-9, and which was acquired by the inventor and depositor of the present report. This document shows a machine for packing chicken including all ideas of previous solutions that makes the process fully automated: from the poultry receipt to the closing and sealing of the package. This automation take into account the entire manufacturing process, such machine is composed of system for receiving the chicken from the freezer line, centralizing through set of funnels and cylinders, and supply packaging system at the lower part of this stock of funnels; this machine provides a carrousel system with distinctive chicken packaging, being a position for receiving chicken within the packaging, other position for the closing and sealing of the packaging and third positioning to discard the chicken which has been packed again for the line. The carrousel has an interlinked movement through clutch system containing chains which perform all their movement. Such machine, as described in this aforementioned, has revolutionized the chicken packaging system, or similar poultries, without having to complete any step by the operator.
A problem associated with this machine is the way to realize the chicken package process of such machine, closing and sealing package is very difficult. The chambers, established in the carrousel, realize two types of movement: one of transfer, which is the carousel rotation as a whole, that allows a change on the position of such chambers, for receiving chicken, closing and sealing of the package, and disposal of the packaged chicken, and another rotation movement around the own compartment axis: this rotation movement that allows to realize closing and sealing of the packaging. It is provided in each compartment a fixing package system, containing clamps which open and close by pneumatic control, and by closing, the chamber turn performing the closing of the packaging and the guide for the sealing mechanism, which contains a blowing system, with a cotter shear pin to remove the edge package, the surplus, which is located on the clamp. All the movement was realized by a mechanism containing clutch interconnected by chain.
As indicated with the brief explanation above, the way to closing and sealing package with this machine is very difficult; requires a series of mechanism, in each compartment which receives poultry including the mechanism for securing the package, pneumatic controls, the rotation of each chamber, the mechanism which is provided in each chamber for moving the packaging to the sealing system etc., in addition to the mechanism containing clutch and chains for the execution of the entire assembly movement. This undertaken configuration causes several problems such as many stops during setup and maintenance of the chains, clutches; the possibility of breakdown and imbalances are higher, and any clamp breakdown of a compartment or any other piece could affect the entire machine; it is required a huge quantity of sensors to control each step to be carried out for each compartment. Another problem is linked to the surplus of CUT package, once this surplus has no destination, that is to say, when they are CUT, these will fall on the machine causing series of drawbacks, such as residues accumulation within the machine, dirt, etc.
In order to seize all knowledge and technical information available, such as market necessities, it was sought to develop a machine for packaging poultries enjoying all advantages of other solutions as revealed previously, document contents of the aforementioned patents, and with the purpose to automate entirely, however, solving issues contained and not solved by current technical status, including particularly the last machine as referred above, offering a solution that takes into account the entire necessity produced by the market.

The packaging module (140) is pulled by driving element (142) and realizes rotation movement by step, enabling the compartment (141) to advance from a closing and sealing position and subsequently to a package liberation position; the compartment (141) is simple, easy to maintain, without big mechanical devices.
Furthermore, such machine (1) provides a closing module (150), containing lower extremity (151) responsible for closing package which contains poultry inside; provides a sealing module (160) of the package. After the sealing, the compartment module (140) turns another step and places chicken, already packed, in the part of package liberation for an output conveyor (3).
The arrival of chickens and its parts of the equipment occurs through the feeding conveyor (100) which receives poultry possibly from the assembly line conveyor (2); the feeding conveyor (100) is responsible for directing chickens to be packed; they are positioned along the feeding conveyor (100). As described on the
After passing by the feeding conveyor (100), the poultry, for example, the chicken and/or its parts, falling in the set of funnel (110), by which goes down until the package; the funnel (110) has angulations and geometrical shapes considered as compatible to allow such poultry displacement until the package. The set of funnel (110) provides, before the funnel mouth (110), a piston in line (111) centralized with the funnel axis (110) that performs forward and retreat movement established in the store department (130), this package is open though opening mechanism (120), positioned in face of department store (130), containing forks (121) which advance and retreat towards store department (130), by opening package with the aid of slipstream (131) established in the store department (130). Furthermore, the poultry is pushed into the chamber (141) of packaging module (140) to continue the process.
The picture 6 shows in detail this set of funnel (110), which contains funnel (110) with opening mechanism (113), that allows to open its tip for passing the chicken; a piston (111), which is established before the funnel mouth (110), with extremity in line (114) centralized with the funnel axis (110) that advances and retreats in relation to the chamber (141) with the aid of guides (112), pushing the chicken until the compartment (141) of packaging module (140). Such funnel package (110) contains a quick change (115) to facilitate the removal for cleaning, as well as auxiliary accessories which help in this process, including in the process of funnel locking (110) into the equipment in itself. The guides (112) are self-lubricants.
