Abstract

PROBLEM TO BE SOLVED: To provide a calibration method for obtaining actual collected milk quantity not being different from an actual milk quantity by adding a holdup in piping when initial milk-collecting operation is performed. SOLUTION: This method comprises the following steps: coupling a milk- collecting pump 11 to an air separator 5; coupling the air separator to a flowmeter 10 through a connecting tube 4; coupling a supply tube 3 between the flowmeter 10 and a milk-collecting tank 1; coupling the pump 11 to a milk-sucking tube 7 so that milk is collected while transferring from a milk-storing vessel 12 to the tank 1 and; adding a quantity corresponding to a holdup existing between the pump 11 and the flowmeter 10 to an accumulated quantity of milk measured with the flowmeter 10 when the initial milk-collecting operation is over at an operator's round to be corrected and to find an actual collected quantity of milk. The method can remove the misreading of divisions of a gauge, and enables correction by adding a previously set quantity added to be performed even if a real collected quantity of milk in the initial milk- collecting operation differs from a measured quantity of collected milk measured with the flowmeter and can impart accurate actual collected quantity of milk.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milk collection system which tours a contract farmer who produces milk, and collects milk stored in a milk storage tank in each farmer by a milking truck.
At the time of the first milk collection, the amount of stagnation remaining in the device and the piping up to the flow meter is set in advance, and this is added and corrected at the end of the first milk collection work, and the first milk collection amount is corrected to the actual milk collection amount About the method.

[0002]

2. Description of the Related Art Conventionally, milk has been produced by each farmer every day from cows bred by the farmer, and the milk that has been milked is temporarily stored in a milk storage tank installed in the farmer. Has become. Then, the milk stored in the milk storage tank is collected by a milk collection truck of a milk collection company which is patrolled by contract. This milk collection truck is equipped with a milk collection tank and a milk collection pump that sucks milk into the milk collection tank, and the amount of milk milked at that time by each farmer is provided in the milk storage tank. At present, the scale of the gauge is directly read by visual inspection, and the person in charge of collecting milk manually writes it on a slip to obtain the actual amount of collected milk.

[0003]

However, in the work of collecting milk by patroling the contract farmers as described above, the scale of the gauge is directly read visually before starting the work each time the work is performed. After this, the milk collection staff performs the milk collection work in the milk collection tank, and when the work is completed, the gauge scale is directly read again visually and the difference is entered in the slip as the actual milk collection amount. As a result, the scale of the gauge was read by mistake, or the entry was mistaken or the entry was misread. Therefore,
Recently, the milk collection truck is equipped with a flow meter for measuring the amount of collected milk, and this is connected to a milk collection pump for measurement. However, air bubbles are generated in the stirred milk. For this reason, when supplied to the flow meter while containing air bubbles, an error occurs between the actual milk collection amount and the air mixed between the milk collection pump and the flow meter. At present, a tank-shaped air separator is always provided for separation from milk.

[0004] When an air separator is disposed between the milk collection pump and the flow meter via a pipe as described above, the milk collected by the milk collection pump does not pass through the flow meter in the first milk collection operation. It only stays in the air separator, so that it passes through the flow meter after staying in the air separator for a predetermined amount, so that at the end of the milk collection work, this stays stagnant, and the actual milk collection actual amount There is such a problem that a difference is generated between the measured milk collection amount measured by the flow meter and the measured milk collection amount.

[0005] An object of the present invention is to solve such a problem and add the staying amount in the pipe and the air separator in the first milk collecting operation to the measured milk collecting amount so that there is no difference between the measured milk collecting amount and the actual milk collecting amount. An object of the present invention is to provide a correction method for obtaining an actual milk collection amount.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to go around a farm where milk is stored, and to store milk in a milk storage tank 12 of a farm to which the milk is stored.
In a milk collection system using a traveling milk collection truck 2 that collects milk by a milk collection pump 11 into a milk collection tank 1 mounted on a milk collection truck 2 from the air collection device 2, an air separator 5 is connected to the milk collection pump 11 via a connection pipe 6. And a flow meter 10 is connected to the air separator 5 via a connection pipe 4.
A supply pipe 3 is connected between the milk collecting tank 1 and the milk collecting tank 1, and a milk sucking pipe 7 is further connected to the milk collecting pump 11 so as to collect milk from the milk storage tank 12 at the patrol destination to the milk collecting tank 1. Then, either at the start or at the end of the milk collection work of the first milk collection work at the patrol destination, the milk collection amount accumulated by the flow meter 10 stays between the milk collection pump 11 and the flow meter 10. This is attained by providing a method for correcting the initial milk collection amount by adding a preset amount corresponding to the staying amount and correcting the result to obtain the actual milk collection amount.

[0007]

FIG. 1 is a block diagram showing an embodiment of the present invention.
4 through FIG. 2 and 3, 1
Is a milk collection tank mounted on the milk collection vehicle 2, and the other end of the supply pipe 3 whose one end is connected to the flowmeter 10 is fixed to the upper part of the milk collection tank 1. An air separator 5 is connected to the flow meter 10 via a connection pipe 4, and the milk collection pump 1 is connected to the air separator 5 via another connection pipe 6.
1 is connected. This milk collection pump 11 sucks milk through an autosampler 13 that extracts a sample for checking beforehand whether foreign matter is mixed in milk collection from a milk storage tank 12 installed in each farmer. A tube 7 is connected, and the end of the sucking tube 7 is connected to a milk storage tank 12 by extending the tube. on the other hand,
The connection pipe 4 is provided with a discharge valve 8. By closing the discharge valve 8, milk is not discharged from the pipe and the flowmeter 10 to the outside.

A transmitter (not shown) for transmitting a pulse signal to the flow meter 10 when a fluid flows therethrough.
When the milk sucked by the milk collection pump 11 and the air separated by the air separator 5 flows through the flow meter 10 and is supplied into the milk collection tank 1, a pulse signal is accordingly generated. Is to be sent. As shown in FIG. 1, the transmitter of the flow meter 10 is connected to an on-vehicle arithmetic processing unit 20 via a signal line 21. 22 is connected via an output line 23.

Further, a memory card 24 for storing the milk collection data from the flow meter 10 for each farmer is detachably attached to the on-vehicle arithmetic processing unit 20, and this memory card 24 is inserted into the milk collection tank 1. It is to store milk collection data by a pulse signal transmitted according to the amount of milk that is collected. The actual milk collection amount as this milk collection data is obtained by calculating a pulse signal,
This actual milk collection amount is a value calculated by multiplying the milk collection amount per one pulse of the flow signal by the number of accumulated pulses. This memory card 24 is a computer 2 to which a card reader 25 installed separately, for example, installed in an office or the like is connected.
6 by operating the computer 26 by inserting it into the card reader 25 of No. 6, it is possible to perform the work processing such as totaling the actual amount of milk collection for each milk collection truck 2 and the production results for each farmer in a short time.

As described above, in a milk collection system in which the flowmeter 10 is mounted on the milk collection vehicle 2 to automatically measure the actual amount of collected milk, a person in charge of milk collection travels around the contract farmer with the milk collection vehicle 2 equipped with this system. When collecting milk at each farmer, when the collection milk truck 2 finishes the traveling milk collection work of the day, the milk collection tank 1 and each device through which the milk passes are in a state of being cleaned and sterilized. Before the milk collection operation, the milk in the milk collection tank 1 is empty. In this state, when the milk collection truck patrols the farmers and the first farmer starts the first milk collection work, the work starts by first connecting the sucking tube 7 to the milk storage tank 12. Thereafter, as shown in FIGS. 1 and 4, when a switch (not shown) for starting the milk collection work is turned on, the on-vehicle arithmetic processing unit 20 is operated and the milk collection pump 11 is operated.
Collection of milk begins. The milk thus collected enters the air separator 5, where the milk from which the air has been separated passes through the flow meter 10. At this time, a pulse signal is transmitted from the flow meter 10, and this signal is transmitted to the on-vehicle arithmetic processing unit 2.
Entering 0, the milk collection data is integrated.

On the other hand, at the start of this work, the milk collection pump 1
1 operates to collect milk, but no signal is output since milk is not yet flowing to the flow meter 10 because it is only supplied to the pipes and the air separator 5. That is, the measured milk collection amount is a measurement value smaller by a predetermined amount than the actual milk collection amount from the milk storage tank 12. For this reason, an operation switch for adding the milk collection amount corresponding to the milk storage amount in the piping from the milk collection pump 11 to the flow meter 10 and the air separator 5 that is set in advance by the milk collection person at the same time as the work start. By turning on (not shown), the milk collection amount as an initial addition amount is added in advance. Subsequently, the milk that is supplied to the pipe and the air separator 5 in a predetermined amount and from which the air is separated in the air separator 5 continuously passes through the flow meter 10, and a pulse signal is transmitted from the flow meter 10. . This allows milk collection tank 1
The amount of collected milk is collected by the in-vehicle arithmetic processing unit 20 and added to the initial addition amount to correct the actual amount of collected milk.

When the milk collection operation is performed in this way and the milk collection operation from the milk storage tank 12 is completed, the pulse signal from the flow meter 10 is stopped, and the milk collection integration process in the on-vehicle arithmetic processing unit 20 is started. The operation ends, and the milk collection pump 11 stops operating.
On the other hand, in the present embodiment, the addition operation of the initial addition amount is performed at the start of the work.
After the measurement of the milk collection amount is completed, an operation of adding the initial addition amount may be performed to obtain the actual milk collection amount. If it is not necessary to add the first addition amount and correct it, the operation switch for the first addition remains OFF.

Thereafter, by turning on an output switch (not shown) of the in-vehicle arithmetic processing unit 20 to the printer 22, necessary information such as the producer name, the actual amount of collected milk, and the date is printed on the slip. Then, the slip is passed to the producer, the sucking tube 7 is removed from the milk storage tank 12, and the sucking tube 7 is removed from the milk collecting truck 2.
To complete the first collection of milk at the farm. On the other hand, the milk collection data in this milk collection operation is stored in the memory card 24.

Subsequently, as shown in FIG. 4, the milk collection person moves the milk collection cart 2 to the next contract farmer, connects the sucking tube 7 to the milk storage tank 12 again, and collects the milk at the destination. Start milking.
At this time, the flowmeter 10 operates simultaneously with the start of the operation of the milk collection pump 11, a pulse signal is transmitted, and the milk collection integration processing in the on-vehicle arithmetic processing unit 20 is performed. Thereafter, when the milk collection operation is completed and the operation of the milk collection pump 11 is stopped,
The milk collection integration processing in the on-vehicle arithmetic processing unit 20 is also completed,
Printing of the actual amount of collected milk by the printer 22 becomes possible. At the start of the work at this time, the milk from the milk collection pump 11 to the flow meter 10 and the milk at the time of the first milk collection have already accumulated in the air separator 5, so that the correction of the actual milk collection amount thereafter is not possible. This is unnecessary, and normal milk collection work can be repeated.

When the milk collection truck 2 having completed the predetermined traveling milk collection operation returns to the company, the memory card 24 inserted and attached to the on-vehicle arithmetic processing unit 20 is removed, and this is removed. By inserting the card into the card reader 25 installed in the office and operating the computer 26, necessary processing is performed on the milk collection data stored in the memory card 24, the data is calculated and totaled, and the result data is calculated by the computer. 26.

[0016]

According to the present invention, as is apparent from the above-described embodiment, the milk collection tank 1 mounted on the milk collection truck 2
In a milk collection system with a traveling milk collection truck 2 that collects milk from a milk storage tank 12 by a milk collection pump 11, an air separator 5 is connected to the milk collection pump 11 via a connection pipe 6 and connected to the air separator 5. A flow meter 10 is connected via a pipe 4, and a supply pipe 3 is provided between the flow meter 10 and the milk collection tank 1.
Is connected to the milk collection pump 11 to collect the milk from the milk storage tank 12 at the patrol destination to the milk collection tank 1. Either at the start or at the end of the operation, the milk collection pump 11 applies the flow meter 10
This is an initial milk collection amount correction method in which a preset amount corresponding to the amount of stagnation that has accumulated during the period has been added and corrected to obtain the actual milk collection amount.

For this reason, in the work of collecting milk while patroling the contract farmers, each time the milk collection work is performed, the milk collection person reads the scale of the gauge of the milk storage tank before starting the milk collection, and then reads the scale in the milk collection tank. When this operation is completed, the operation of directly reading the scale of the gauge again visually and entering this difference as the actual amount of collected milk by hand on a slip becomes unnecessary.
Eliminating this operation also eliminates the possibility of reading the scale of the gauge by mistake or making a mistake. Furthermore, an air separator is arranged between the milk collection pump and the flow meter via a pipe, and in the first milk collection operation, the milk collected by the milk collection pump does not pass through the flow meter without passing through the flow meter. Although the milk is only stored in the air separator, the milk is stored in a predetermined amount in the air separator and then passes through the flow meter, so that the actual milk collection amount and the flow meter at the end of the milk collection work are measured. Even if there is a difference between the measured milk collection amount, it can be corrected by adding the amount corresponding to the preset retention amount, and the accurate actual milk collection amount can be obtained from the first milk collection time And the like.
