Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a pair of left and right doors that are provided in the middle of a walkway through which a walking animal passes and are opened and closed to allow the walking animals to pass separately. Each of the doors is for a walking animal that is slidably supported along the width direction of the door in a closed state in which the doors are arranged side by side in the width direction of the passage so as to close the path of the walking animal, and in an open state that is located beside the passage. Regarding the gate.

[Conventional technology]

The gate for such a walking animal opens and closes a pair of left and right doors provided in the middle of a walking passage through which the walking animal passes,
The purpose is to separate and pass the walking animals one by one in order to weigh and test the walking animals. Therefore, since walking animals often pass close to each other when passing through a walkway, the pair of left and right doors is frequently opened and closed, but such a door can be opened and closed by the left and right doors. It has the advantage that the passages can be opened and closed quickly and the walking animals can be separated efficiently.

By the way, it is conceivable to construct the left and right doors by using a plate body or the like so that the entire body cannot be seen through. However, this configuration has the disadvantage of increasing the weight of the door, and because animals, especially cows and other weak animals, have the property of disabling to proceed unless the front of the animal can be seen, the animal should be placed in front of the door. It has been confirmed that it is not suitable as a gate for animals because it is difficult to proceed or make it stand by.

For this reason, conventionally, it has been practiced to use a lattice-shaped frame or the like so that the entire door can be seen through.

[Problems to be solved by the device]

Of course, the height of the door needs to be high enough to prevent animals from getting over, but as the pair of left and right doors are frequently opened and closed as described above, the weight and simplification of the door should be reduced. For the purpose of illustration, it is desirable to omit the part corresponding to the feet of the animal.

However, if the part corresponding to the animal's feet is simply omitted, the animal may thrust its head into the gap between the aisle surface and the lower edge of the door, and the animal cannot be properly stopped immediately before the door. It was a thing.

The present invention has been made in view of the above circumstances, and an object thereof is to appropriately stop an animal immediately before a door while omitting a part corresponding to the foot of the animal. The point is to provide a gate for possible walking animals.

[Means for Solving the Problems]

The gate for a walking animal according to the present invention is provided in the middle of a walking path through which a walking animal passes, and a pair of left and right doors, which are opened and closed to separate the walking animals one by one, respectively, have a passage for the walking animal. It is also supported slidably along the lateral width direction of the door in a closed state arranged side by side in the lateral width direction so as to close the door, and in an open state positioned at the lateral side of the passage, the first characteristic of which is Each of the doors is formed such that a lower end edge of the door is positioned above the upper surface of the passage with a space therebetween, and a lower portion of the door is configured to be invisible.
The other upper portion is configured to be transparent.

A second feature is to specify a preferred form of the first feature, in which the see-through portion of each door is formed by vertically arranging a plurality of elongated frames along the door lateral width direction. .

The third feature and the fourth feature specify the use object of the gate of the present invention. In the third feature, the gate is installed at the exit side of the restraint space for weighing or inspection that the walking animal passes through. The fourth feature is to specify the installation on the inlet side of the constraining space for weighing or inspection.

A fifth feature is to specify a preferable installation mode of the doors, and a linking means for interlockingly connecting the pair of doors is provided so that the pair of doors move integrally between a closed state and an open state. There is a point.

 The operation of the first feature is as follows.

When a walking animal passing through the walking passage reaches a position on the front side of the door provided in the middle of the walking passage and the door comes into the field of view of the walking animal, the lower part of the door cannot be seen through. Since the other upper part can be seen through, the walking animal can proceed to the position just before the door without being disliked while checking the front through the see-through part.

And since the lower part of the door is invisible,
Although the lower edge of the door is formed so as to be positioned above the upper surface of the walkway at a distance from the upper surface of the walkway to reduce the weight of the door, there is a gap between the lower edge of the door and the upper surface of the walkway. Walking animals do not stick their heads. The reason can be considered as a main factor that the gap between the lower end edge of the door and the upper surface of the walkway seems to be small when, for example, the animal located immediately in front of the door looks downward.

The operation of the second feature is as follows.

In order to configure the door so that it can be seen through, it is conceivable that long frames along the vertical direction are arranged side by side in the width direction of the door.
It has been confirmed that it is easier to stabilize the spirit of animals such as cows by arranging a plurality of elongated frames arranged in the vertical direction along the width direction of the door.

The action of the third feature is utilized for the gate of the exit of the restraint space for weighing or inspection, and the action of the first feature and the action of the second feature smoothly introduce the animal into the restraint space. The animal can be kept calm in the restraint space and an appropriate weighing value and an appropriate test result can be obtained.

The action by the fourth feature is utilized for the gate of the entrance of the restraint space, and by the action by the first feature, the action by the second feature and the action of the third feature, the action of the entrance of the restraint space is achieved. With the opening of the gate, the animal that had been waiting immediately before can be swiftly advanced into the restraint space.

The function of the fifth feature is that the pair of left and right doors can be opened and closed at once, so that the opening and closing operation can be performed quickly and appropriately.

[Advantage of Invention] According to the first feature, the animal can be favorably advanced just before the door, and the part of the door corresponding to the foot of the walking animal is omitted, and each walking animal is individually A door that can be opened and closed more frequently due to the work of separating it, while reducing the weight and simplifying the door, but it is possible to prevent a walking animal from thrusting its head into the gap between the upper surface of the walkway and the lower edge of the door. As a result, a gate for walking animals, which is excellent in practical use and production, has been obtained.

According to the second feature, the animal can be further advanced toward the door, which is effective in enhancing the effect of the first feature.

According to the third feature and the fourth feature, it is advantageous to obtain an appropriate weighed value and an appropriate inspection result, and it is advantageous to quickly weigh and inspect.

According to the fifth feature, opening and closing operations of the left and right doors can be appropriately performed, which is convenient for enhancing the effect of the first, second, third, or fourth feature.

A buzzer (54) is provided in the instrument box (B). The first display section (48) displays the identification number of the cow input by the ten-key (50), the weighing value data that is read at any time, and the second display section (49) displays the calculation. The static weight value of the selected cow is displayed.

Here, the operation of the weighing section (S) and its operating procedure will be briefly described.

The cow is guided by the entrance chute (1) and the entrance gate (2B)
When you come to the front, press the numeric keypad (50) to enter the identification number of the cow you read. After finishing the input, operate the first operation lever (29) to open the entrance gate (G ₁ ) and place the cow on the weighing machine (2). Once the cow is on the balance (2), close the entrance gate (G ₁ ). When the static weight value is obtained by the measurement processing unit (H), the buzzer (54) operates to notify the end of weighing. Then, the outlet gate (G ₂ ) is opened to lower the cow from the weighing machine (2), the print key (53) is pressed, and the static weight value displayed on the second display section (49) is printed with the cow identification number. Print it on (46).

That is, by opening and closing the pair of left and right doors (20), the cows passing through the walking passage are separated and walked on the weighing machine (2) to measure the static weight of the cows.

Next, the measurement processing unit (H) will be described in detail. As shown in FIG. 9, this measurement processing unit (H) receives an input means (55) for receiving a weighing value signal (analog electric signal) obtained by adding the detection signals of the four load cells (7), and receives it. A central control unit (56) for obtaining the static weight value by sequentially fetching and storing the weighing value signal as time series weighing value data.

The input means (55) includes an amplifier (55A) for amplifying the weighing value signal, a low-pass filter (55B) for smoothing the output of the amplifier, and a quantizer A for smoothing the signal with a predetermined sampling time. It consists of a / D converter (55C).

The main component is a microcomputer.

Next, the procedure for determining the static weight of a cow walking on the weighing machine (2) will be described.

FIG. 10 is a graph of an amplifier output of an analog signal indicating a weighing value sent from the load cell (7) as a cow walks on the weighing machine (2). In this graph, the area indicated by a is a state in which only the front paws of the walking animal are on the scale (2), and the area indicated by b is a state in which the total weight of the cow is on the scale (2), The area indicated by c is a state in which only the hind legs of the cow are on the scale (2).

The output of this amplifier is passed through a low pass filter (55B),
The signal becomes a smoothed signal as shown in FIG. FIG. 12 is an enlarged view of the area indicated by b above. From this figure, it can be understood how the analog weight value signal is sampled and quantized.

After the weighing is started, when the quantized weighing value data (hereinafter simply referred to as weighing value data) becomes larger than a set value (K) which is slightly larger than the weight of the weighing machine (2), the cow weighs. The weighing value data is sequentially stored in the memory (56A) as a sampling sequence as if the user started riding on the vessel (2). The storage is continued until the set time (T ₀ ) for storing the sample data has elapsed.

Next, the gait periodicity evaluation means (56B) obtains the maximum value: Wmax from the stored sampling data, and from this, a data group within a predetermined range, the maximum value in this embodiment,
The data group having a value of 90% or more is regarded as the weighing value data group when the total weight load of cattle is on the weighing machine (2). In this embodiment, 0.9 is multiplied, but the value (n) to be multiplied can be a number greater than 0.8 and less than 1.

The gait periodicity evaluation means (56B) further evaluates the gait periodicity by examining the maximum value from the weighed value data group. In the case shown in FIG. 12, the maximum value is
There are five of W1, W8, W15, W23, W29.

Next, the valid data section setting means (56C) sets the valid data section (T) with the time point at which the first maximum value W1 appears as the starting point, and the time point at which the maximum value W23 of the fourth time here appears as the end point. Will be set.

However, in the setting of this valid data section, how many walking cycles are included can be set in advance depending on the type of walking animal, the natural frequency of the weighing machine (2), and the like.

The sampling data in the valid data section (T) set in this way are averaged by the computing means (56D), and the static weight value of the cow walking on the weighing machine (2) is calculated. By this measurement, for example, an animal weighing 1000 kg can be detected with an accuracy within an error of 1 kg.

[Another embodiment] The doors (20) of the gates (G ₁ ) and (G ₂ ) on the inlet side and the outlet side may be opened and closed by an actuator such as an electric motor. In that case, an opening / closing operation tool Switches can be used as (29) and (33).

When the gate of the present invention is applied to the weighing machine (2), various means can be used to obtain the weight of the animal from the weighing value data of the weighing machine (2). In other words, if the weight of the animal is obtained from the weight value data obtained along with the walking while actively walking the animal as described in the above embodiment, the weight of many head animals can be efficiently measured. However, various means can be used such as stopping the animal on the weighing machine (2) and determining the weighted value of the stopped state as the weight of the animal.

It is advantageous to use the color of the door (20) of the gates (G ₁ ) and (G ₂ ) on the entrance side and the exit side that is good for stabilizing the spirit of walking animals. Of course, when the fence (4) and the chute (1), (3) at the entrance and exit are provided as described in the above embodiment, it is desirable to use a color that is good for the mental stability of the walking animal.

The gate of the present invention is used as a gate for opening and closing the passage formed in the constraining space for weighing, that is, the passage formed on the weighing machine (2) described in the above embodiment, and various passages. Can be used as a gate to open and close.
For example, even if the restraint space is a restraint space for inspection such as temperature measurement, it can be carried out in the same manner as in the above embodiment, and can be used to open and close the entrance and exit portions and the middle portion of the animal guide passage.

Further, the gate of the present invention can be applied to various walking animals such as horses, sheep, goats, and chickens in addition to cows. The specific configuration of each unit can be changed in various ways according to the object of use.
