Definitions

  • the invention is developed to be used in milking systems, wherein it relates to a pulsation monitoring claw that enables monitoring the intensity, frequency and duration of vacuum applied to animal teats during milking and warns the user if required limits are exceeded.
  • teat diseases occur in time especially in bovine animals due to high yield. These diseases of udder directly affect milk production and in most instances, milk obtained from other healthy udders can't also be used as "product" for days due to the administered antibiotic treatment. Used antibiotics are easily transmitted form the animal body to the milk. Economically utilizing the milk containing antibiotics is impossible both health-wise and from the technical aspect.
  • the fundamental method of fighting disease in a business is to eliminate the conditions that cause the disease.
  • One of the main factors of disease formation in teats is the intensity, frequency and duration of the vacuum applied on the animal's udder.
  • Pulsation ratio is shown as "X/Y” and this means vacuum is applied during "X" percent of the duration of one cycle; and the udder is in squeezing, i.e. resting stage during the remaining "Y" percent.
  • X/Y vacuum is applied during "X” percent of the duration of one cycle
  • the udder is in squeezing, i.e. resting stage during the remaining "Y” percent.
  • High pulsation ratio e.g. 70/30
  • might reduce milking duration due to long vacuum period for example when vacuum is applied in 70% of a second.
  • an incompatibility occurs between the flow of milk from the teat and the operation of the machine especially in old cows.
  • the udder will remain under vacuum longer than the optimum period and it will become defenseless against microbes due to the deformation of udder canals.
  • Low pulsation ratio e.g. 30/70
  • increases milking duration and longer milking duration will similarly result in longer exposure to vacuum and render the udder defenseless against bacteria.
  • Low or high pulsation frequency is also harmful to the udder.
  • very low pulsation frequency less than 30 per minute
  • pain is felt on the teat due to insufficient blood circulation.
  • Cows respond to pain by kicking.
  • high pulsation frequency more than 60 per minute
  • teat canal is overstrained and loses its inherent power to prevent microorganisms from entering the udder.
  • FIG 4 view of the milking claw applied to teats is shown.
  • the right cup When the right cup is in squeeze position, the left cup is in release position. In squeeze position, vacuum applied to the udder and flow of milk from the udder is stopped; whereas in release position vacuum is applied to the udder in order to enable milk outflow.
  • Teat cups are connected to the milking claw after hoses connected to the vacuum inlet (21 ). Hose distance is fixed here.
  • the rubber part placed inside the teat cup and squeezing the udder is called teat cup liner. Teat cup liner and the hose, referred to as vacuum inlet (21 ) constitute a single piece together. Teat cup liners are manufactured as standard. Vacuum enabling the milking process is transmitted to the teat cup liner through milking claw and enters the chamber, in which the udder is placed, via the vacuum inlet (21 ). If vacuum is also provided through the pulsator inlet (22) in the meantime, internal and external pressure will be equal and thus the teat cup liner will preserve its form and milk flow will be provided by applying vacuum directly to the udder.
  • the pulsator inlet (22) If air with atmospheric pressure enters the pulsator inlet (22) while there is vacuum inside the internal chamber, i.e. the chamber in which the udder is placed; the pressure of the internal chamber will be negative and that of the external chamber will be positive leading to closing of the liner by contracting inwards and cessation of application of vacuum on the udder. Meanwhile, milk flow stops and udder is allowed to rest.
  • Pulsator is the component that enables vacuum or air entry from the pulsator inlet (22) as shown in Figure 4. It connects the pulsator inlet (22) to the vacuum pipeline and the environment atmosphere respectively according to the desired pulsation settings. Once the pulsator starts applying vacuum to the mentioned chamber, all air in this area and the hose should be evacuated by vacuum for the liner to go back to its old form. If the hose is extended or the diameter of the hose is increased, squeezing process will last longer than it's supposed to because air inside will be evacuated later; and the desired pulsation ratio will change. Therefore hose diameter and distance between the pulsator and the teat cup is important for the pulsation ratio.
  • vacuum measurement is performed with mechanical vacuum gauges from one point (outlet of the vacuum source) on the vacuum pipeline.
  • vacuum passes through many different sized joints and junctions until it reaches the milking claw, i.e. the cup on the animal's udder. Therefore, the value at the outlet of the vacuum source is different than the value that reaches the animal's udder.
  • another major factor in mastitis disease formation is the pulsation ratio and frequency; and pulsation ratio cannot be measured in this system.
  • Present invention relates to a pulsation monitoring claw developed in order to eliminate the abovementioned disadvantages and bring new advantages to the relevant technical field.
  • Main object of the invention is to provide a pulsation monitoring claw, which measures the intensity, frequency and duration of vacuum applied to each teat of the animal during milking process and evaluates the acceptability of these parameters by a processor unit contained within itself.
  • Another object of the invention is to provide a monitoring claw that automatically becomes active during milking process and inactive after the milking process is finished; therefore measures the ratio, frequency and speed of pulsation during every milking process without the need to interfere by the user.
  • Another object of the invention is to provide a monitoring claw that can communicate with external units in a wired or wireless manner. Therefore, all performed measurements (pulsation ratio, vacuum intensity, frequency and period etc.) can be transferred to external systems and recorded, interpreted and similar actions can be performed.
  • Another object of the invention is to provide a monitoring claw that can be integrated with any kind of mechanical or electronic milking system. For instance, besides being able to be used in mobile milking machines that are only made of mechanical components and that do not contain any smart components; monitoring claw will also be able to be used together with automatic milking systems and/or advanced herd management systems.
  • present invention relates to a pulsation monitoring claw, which comprises one milk tube provided for each milking cup attached to teats of the animal to be milked and which enables measuring the intensity, frequency and duration of vacuum applied on teats during milking process.
  • the mentioned pulsation monitoring claw is characterized in that it comprises:
  • a central processor unit that calculates the pulsation ratio for each teat by using data from the mentioned sensors and evaluates the acceptability of this value
  • a trigger unit to trigger the central processor unit in order to activate the power supply when milking process starts
  • Another preferred embodiment of the invention comprises an external systems connection unit in order to enable wired and/or wireless communication of the central processor unit with external electronic units.
  • Another preferred embodiment of the invention comprises warning lights, each of which corresponds to one teat and enables warning the user by being switched on by the central processor unit when level of vacuum applied to the corresponding teat is not acceptable.
  • mentioned trigger unit is a direction sensor that activates the power supply during the milking process and inactivates it when milking process is finished by detecting the direction change occurring in the pulsation monitoring claw.
  • mentioned trigger unit is a pressure sensor that activates the power supply by detecting the negative pressure occurring in the claw during the milking process and inactivates it upon disappearing of the pressure when milking process is finished.
  • mentioned trigger unit activates and inactivates the power supply in accordance with a command received from an external unit by the unit for connecting with external systems.
  • mentioned trigger unit is an on-off button that is placed on the pulsation monitoring claw and that enables activating and inactivating of the power supply manually.
  • a smart power management system is provided with the trigger unit that controls the power supply within the scope of the pulsation monitoring claw of the invention. Therefore, it is ensured that the power supply is activated only during milking process and inactivated when milking process is finished. This extends the lifetime of the power supply.
