Can you imagine the application of poultry boning machine?

If a robot can remove bones from fresh chickens and keep the skin, is there anything it can't do? Maybe it can challenge itself to remove bones from the fish. Actually to make the robot has the ability to process chickens of different size and weight, and remove the bones without destroying the meat and skin, it is required to have accurate sense of space, which is the cutting-edge technology in the robots field indeed.

At present, Georgia institute of technology has developed a system, which can finish the boning process automatically with the use of advanced image technology and mechanical arm. It may make revolutionary impact on the poultry processing market. It adopts a 3D video system to decide where to cut, and then the mechanical arm will implement the boning process precisely, which can avoid the bone scraps left in chickens effectively.

According to the announcement of Gary McMurray, the head of food processing department at Georgia institute of technology, because of the different sizes and shapes of chickens, they established a set of induction linkage system to make it be suitable for all chickens. Chicken meat is the main agricultural product in Georgia, and the annual production value is as high as two billions of dollors.
This newly released robot adopts double degree of freedom mechanical arm, and the chicken are controlled by a six-degree of freedom mechanical arm. The video system detects the chickens using force feedback algorithm firstly, and then the six-degree of freedom mechanical arm moves the chicken to the cutting mechanical arm. And this system can also be applied to process other poultry after a simple adjustment, but there are also some people worry that once this robot is produced in a large sale, many people will be at risk of losing their jobs.

KUKA robot brings automation to poultry processing equipment

KUKA was established in 1898 by Johann Josef Keller and Jakob Knappich in Augsburg, and it initially focused on the indoor lighting and urban lighting industries. In 1973, KUKA developed the first industrial robot named FAMULUS in the world, and later KUKA concentrated its business on offering advanced automation solution for industrial producing process. Now it has been one of the leading industrial robots manufacturers worldwide.

KUKA robots can be used for materials handling, processing, stacking, electric soldering and arc welding, and it has been very popular in electrical automation industry, food, plastic and many other industries. It is reported that KUKA robot also brings automation to poultry processing equipment industry today.
KUKA has introduce two six-axis robots: KR30 and KR60. Both of the two robots are equipped with shields to protect them from erosion. The perfect combination of three-dimensional laser measurement system, PC assessment software and the conveyor software forms the core of the automation solution. A hanging conveyor transfors the poultry bodies that have processed by chicken evisceration equipments constantly by the speed of 170mm/s. So the robot must be able to keep up this speed and synchronize with the conveyor. At the same time, the three-dimensional laser measurement system can obtain the date of the whole surface of the poultry body precisely.
Becasue of the different size, weight, and manu other anatomical characteristics of different body, so measurement is very essential. Then the measured date will be transfered to the robot control system by PC assessment software, which can decide the cut date of each poultry body. On the basis of the date, the robot control system can calculate the relevant robot orbit, and then the first KR30 robot, which is equipped with double hook-and-loop will cut off the forehoof at the fixed position, and another KR30 robot was installed on the ceiling, and it will remove the rectum with the rectum cutter. By the remeasurement of the three-dimensional laser measurement system, a hanged KR60 robot equipped with a cleaver will broke the pelvic cavity of each carcass and pre-cut the breast. And then another KR60 robot opens the chest of the carcass, and cut the sternum from the middle precisely.
I believe that with the application of the KUKA robots, meat quality can be fast and accurately controlled and people's health conditions can be well improved.

What poultry farm equipments do we need to build a chicken farm?

Advanced poultry farm equipments are used to creat an ideal living environment for chicken flocks, and improve the production efficiency drastically. Today I will introduce some necessary poultry farm equipments that we need to build an automated poultry farm.

1. Heating equipment
During the brooding stage, especially in the cold winter, we can use electric heating, water heating, central heating, heated brick bed and other heating methods to keep chicken farm at proper temperature. Electric heating, water heating and central heating are relatively cleaner and healthier than other methods. While we have to be careful to prevent a gas poisoning accident if we use coal stove to heat, and heated brick bed might be fuel-consuming, but it is able to keep the temperature constant. Choose the suitable heating method according to the local conditions.
2. Ventilating device
For the open type chicken farms, we can regulate ventilation mostly depends on natural ventilation by controling the windows and skylight. But if in the hot summer, natural ventilation doesn't work neither, and mechanical ventilation should be considered. For closed henhouse, we almost reply on mechanical ventilation completely, and there are two types in general: aspirate type and exhaust type. Some chicken farms use aspirating ventilation, and some others use exhausting ventilation, and you can choose between the two types to suit the occasion.
3. Automatic chicken waterer

From the point of saving water and preventing bacterial contamination, nipple type chicken waterer is the most ideal choice, but because of the low quality and leaking problem, there are few chicken farms choose this type at present. The hanging chicken waterer is the mostly common type in most chicken farms. It is suspended from the ceiling through the hanging loop. The top water inlet tube connect with the main water pipe, and the incoming water flow into the water dish by control valve, which is both healthy and water-saving.
4. Automatic chicken feeder

Hanging chicken feeder is the most common type of automatic chicken feeder, and it is the combination of the appending machine of chain feeding machine. The construction of chicken feeding trough decides if the feed can be fully applied. It will cause feed wastage if the chicken feeding trough is too shallow, and tall feeding trough can greatly reducing feed wastage.
5. Egg laying case
Feeding meat chicken and laying hen can use double-layer egg laying case. Every 4 hens shares a case. The height of the upper footboard from the ground should not exceed 60cm, and the size of each egg laying case is approximately 30cm*30cm*38cm. Both side and the back side is grid, which guarantees the ventilation inside the case. Outside the bottom board there should be a impingement baffle to prevent the eggs slipping off the ground.
6. Dung floor cleaner

The general chicken farms clean the dung manually termly, and there are a few chicken farms use the manure scraper to clean the dung. But the steel wire rope of the manure scraper is easily broken, and the maintenance is not convenient, and it costs much. So it has not been widely used.
7. Poultry cage
Rearing chicken can use both halftone and vertical multilayer brooder, and rearing adult chicken can choose overlapped and stepped poultry cage. Poultry cage can make full use of the space and increase the feeding capacity. Besides, the good health condition can prevent epidemic effectively, it helps save much feed.
8. Lighting equipment
Currently most chicken farms use incandescent lamp as lighting equipment. Many chicken farms are equipped with timer to control the light switch automatically, to take the place of manual control switch, which guarantees the accuracy and reliability of lighting time.
9. Debeaking device
The automatic debeaking device is constructed by transformer, electrical machine, cooling fan and so on. It can finish the complete process of debeaking, hemostasis and detoxification quickly. The maximum temperature of the blade can reach as high as 1020℃ when connect the power, and a blade can process more than 20,000 chicken.

Application and Development on MEMS Optical Switch

MEMS is a mechanical and electrical integration device or system composed by highly integrating MEMS device such as micro structure and micro actuator whose geometric dimensioning or operation size is only at micrometer, submicron even nanometer level and controlling circuit on a very small space of silicon substrate or non-silicon substrate material. MEMS component has characteristic of small size, light weight, low consumption, small inertance and short response time. It can massively integrate microstructure of different function, sensitive direction and actuating direction together to conduct batch copy and massive production by micro electroforming method.

MEMS processing has similar technology with semi-conduct assembly circuit. Its primary characteristic is preparing MEMS by taking use of integrated circuit common technics like photoetching and mechanical erosion and acquiring tender moving structure by finally selecting corrosion technology to release structure unit on the basis of thin film deposition. Entering 90s century, with the successful application of deep groove mechanical erosion technology, bonding technology and other critical technology, bulk silicon micro mechanics gets rapid development and further exploits new technique combined of multiple bulk silicon process and surface micro mechanism technique. This makes MEMS technology not only get rapid development in sensor field but acquire unprecedented development in application and study in fields like optical fiber communication, micro chemical analysis system, DNA analysis and micro robot.
Optical fiber communication enters into optical fiber network age after realizing high speed and high capacity point to point transmission. MEMS has greatly wide application range in optical fiber communication field. Almost each constitutional unit in all optical networks can apply MEMS to manufacture component and develop MEMS. It is the synthesis of multiple technologies like mechanism, electricity, light, magnetism, chemistry, automatic control, sensor technology and information treatment. Make a comprehensive survey of optical fiber communication component development history, we can observe component development trend is bulk conglomeration optical fiber and MOEMS integration. In present situation that integration component is still not quite mature, MEMS or MOEMS optical component has emerged commercialized products.
MEMS technology one very important application in optical fiber communication network is taking use of tender moving micro-mirror to manufacture optical switch matrix. Tender moving micro-mirror can adopt up and down folding method, left and right shuffling method or rotation method to realize connection and break function. MEMS optical switch manufactured by MEMS technology integrates mechanical structure, micro touching component and micro optical component on a same substrate, equipping characteristic of compact structure, light weight and easy expandability. Compared with mechanical optical switch and waveguide mode optical switch, it has better excellent like low insertion loss, small intrusion tone, high extinction ratio, good repeatability and moderate response speed. It has nothing to do with wavelength, polarization, speed rate and modulation system. With long service life and high dependability, it can expand into massive optical cross liking switch matrix.
Global optical fiber communication market has experienced three years hibernation period. After that, with the Alcatel-lucent market share turning good and market value looking up, it rekindles hope springs in people. Though MEMS optical component manufacturers are amidst the winds of change and experience turn of the tide, MEMS technology application field is not only optical communication and still keep strong vitality. It is sure to get wide propagation and application in limitary and civilian fields like communication, navigation, sensor, medical, traffic and aerospace by virtue of its inherent feature and born advantage like research direction diversification, process technique pluralism, system monolithic integration, assembly and packaging unification and application field entirety.

The Mobility Hoists for the Patient

The inability to mobilize patients at home is one of the primary reasons that patients find it necessary to leave the home environment and enter a nursing home when they become temporarily or permanently disabled. Now, patients can solve this problem with portable electric patient lifts.
An electric patient lift may be either a sling lift or sit-to-stand lift. This is an assistive device that allows patients in hospitals and nursing homes and those receiving home health care to be transferred between a bed and a chair or other similar resting places, using hydraulic power. Sling lifts are used for patients whose mobility is limited. They could be mobile patient lifts or overhead lifts. The sit-to-stand lift is designed to help patients with some mobility but who lack the strength or muscle control to rise to a standing position from a bed, wheelchair, chair, or commode. They use straps, vests, or belts (as opposed to slings) to make the transition possible.

There has been considerable effort put forth by nursing advocacy groups to encourage hospitals and nursing homes to adopt "zero-lift" or "no-lift" programs in order to prevent orthopedic injuries in healthcare workers. However such Safe Patient Handling and Movement programs, which require the use of mechanical lifting aids, are sometimes difficult to implement. This is in part due to the time and effort required to safely use lift equipment. Transferring a patient with a lift takes between three and six minutes which are considerably longer than moving a patient manually. Lift manufacturers emphasize that the added time it takes to use lifts is worthwhile since mechanical lifting aids improve caregiver and patient safety and while also preventing patient falls.
Normally, much consideration is given to the patient's comfort and wellbeing during the transfer process. For some patients, the use of a patient lift is more dignified than transferring a patient manually while some consider being hoisted in a sling less dignified. Lifts can enable families or caregivers to mobilize patients in the home setting rather than forcing patients to be relocated to an institutional setting. Safe patient handling is especially important in the area of bariatric care. Bariatric patients who are classified as patient who weigh more than 300 pounds require additional staff training and specialized equipment for transfer, showering, toileting, etc.
While power patient lifts are often used by only one health care worker without assistance, most manufacturers require that two caregivers be present. However, the single caregiver approach makes the patient lift more usable in home care settings where there is often only one caregiver per patient. In either case, patient lifts require special care in their use, as any mistakes made may result in serious injury.
