Description

1 / 5 DEVICE APPLIED IN SEMI-AUTOMATIC CALLUS EXTRACTOR

[0001] This utility model refers to equipment for extracting / grinding calluses from the feet of birds. The equipment consists of shafts, gears, geared motors and retaining bearings, as well as a control panel, and also includes smaller assemblies and parts to facilitate cleaning, ensure operation and assist in adjusting the device's parameters.

[0002] The evolution of industry over the last few decades has been marked by the incorporation of advanced technologies, and automated machines play a crucial role in this scenario. Industrial automation, characterized by the use of automatic systems to perform tasks previously performed by humans, has brought numerous benefits that positively impact efficiency, quality, and productivity in industrial operations. The implementation of automated equipment in meat processing plants ensures efficiency, food safety, and product quality. This automation has significant impacts in various areas, contributing to the improvement of the meat processing industry as a whole.

[0003] Automated machines streamline production and packaging processes, reducing the time required to perform specific tasks. This not only increases operational efficiency but also contributes to reducing labor-related costs and minimizing resource waste. Automation in meat processing industries contributes to improved working conditions. Repetitive, heavy tasks or those performed in extremely low temperature environments can be carried out by automated machines, reducing occupational hazards and promoting a safer work environment for employees.

[0004] In summary, the implementation of automated equipment in refrigeration industries not only boosts operational efficiency but also plays a crucial role in ensuring product quality, compliance with sanitary standards, and workplace safety. This modern approach contributes to the sustainability and competitiveness of these industries in a globalized environment.

[0005] From the state of the art, we can consider relevant the document BR2020230229706 filed on 01 / 11 / 2023 and named “DEVICE APPLIED IN CALLUS EXTRACTOR” filed by the same holder and refers to equipment for extracting / grating calluses present on the feet of birds. The equipment consists of shafts, gears, a motor brake and retaining bearings, as well as a control panel, also comprising a set of smaller parts to facilitate cleaning and ensure operation and assist in adjusting the device's parameters. The object of the present application is a clear evolution of the aforementioned document.

[0006] Another document that can be cited is MU9001384-0 filed on 02 / 08 / 2010 and named “Pneumatic chicken foot callus cutter” refers to equipment developed to improve the yield and hygiene in the chicken foot cutting process. The equipment uses an automatic cutting blade, driven by a piston through compressed air pressure, which provides speed and efficiency to the procedure. The compressed air is admitted into an air preparation unit and pressure regulator. However, the aforementioned equipment only has one orifice to cut the callus, and this is done using a blade, while the claimed model has twenty-six (26) feeding cradles, which are moved through the conveyor belt to the extraction point, which is done with two friction rollers.

[0007] With the aim of improving ergonomic working conditions and consequently increasing the quality of work, presenting a simpler and more efficient solution geared towards industrialization, the present machine was developed to meet all the safety standards of the food industry and performs the function of removing calluses from the feet of poultry in a sanitary manner so that they can be marketed, through an automatic process.

[0008] The object of this utility model is a simple operation and maintenance device, featuring a robust construction with several stainless steel linear guides providing greater stability to the system. The device is basically composed of two geared motors (07 and 11), friction rollers (08), linear guides (09), cleaning piping (15), spray nozzles (16) and other components that will be explained throughout the report.

[0009] The equipment structure is built in stainless steel, polymers and other materials suitable for the food industry, all control of the same is carried out through the control panel (04), the device has several product inlets, where the operator can use all inlets (02) to feed the equipment, which are equipped with a safety system (14) which contains a protection sensor, in case the operator accidentally comes into contact with the conveyor belt of the feeding cradles (12), also including a safety cord (01) for any eventuality during operation.

[0010] The equipment's operation consists of two geared motors (07) transferring the force to the shafts (10) which have friction rollers (08), and another geared motor (11) transmitting the force to the conveyor drive shaft (13) responsible for pulling the cradles (02) to the friction rollers and efficiently extracting the hoof callus, in Petition 870260005587, dated 01 / 21 / 2026, p. 8 / 25 4 / 5 front part of the equipment to a reject chute (03) which excludes the grated part. The part of the paw where pododermatitis is exhibited is pressed against the friction roller (08) which grates completely in order to even out the paw.

[0011] Inside the device above the friction rollers (08) is a cleaning pipe (15) with spray nozzles (16) that keeps the rollers (08) always sanitized, and a nozzle (16) positioned inside the conveyor belt (12) for constant removal of residues that accumulate during the use of the equipment.

[0012] For supplying the cleaning pipe (15) the equipment includes a water inlet (06) which can be at room temperature or boiling for better sanitization.

[0013] The equipment can be operated manually by the operator pressing a control button to start it, or automatically after the process is complete.
