Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gate for walking animals that opens and closes passages for walking animals.

[Conventional technology]

As shown in Fig. 10, conventional gates for opening and closing passages for animals that can walk have been gates in which two doors (50) are pivoted around a vertical axis (Q) so that they can be opened and closed, As shown in Fig. 11, a pair of left and right doors (51) are arranged on guide rails (52) in a closed state in which they are lined up in the width direction of the passage so as to close the passage, and in an open state in which they are moved parallel to the outside of the passage.
There is one that is supported so that it can slide freely. However, the drawings illustrate a case where a passage is formed above the weighing platform (1) and a gate is provided to open and close the entrance and exit of the weighing platform (1).

[Problem to be solved by the invention]

Of the conventional gates mentioned above, those that swing open and close require a locking mechanism that secures the door in the closed state to prevent the door from being pushed open in the longitudinal direction of the passageway by walking animals. . Therefore, the operator is required to open and close the door and the lock mechanism, which is disadvantageous and difficult to handle.

Among conventional gates, sliding type gates do not open even if the door is pushed in the longitudinal direction of the passageway by a walking animal, so the disadvantages of the swinging type door described above can be avoided. However, in this case, the door protrudes outward from the passage in the open state, so there is a disadvantage that space for installing the door must also be secured outside the passage.

The present invention was made in view of the above-mentioned circumstances and to eliminate the above-mentioned drawbacks, and its purpose is to provide a gate for walking animals that is easy to handle and does not require a large installation space outside the passage. It is in the point of doing.

[Means to solve the problem]

The first feature of the gate for walking animals that opens and closes the passage for walking animals of the present invention is that the pair of left and right doors are lined up in the width direction of the passage so as to close the passage, and that the gate is placed on the side of the passage. The door is supported so as to be slidable along the width direction of the door and in the open state positioned along the longitudinal direction of the passageway.

In this case, it is preferable to configure as shown in the method.

That is, the second feature of the present invention is that the inner end of the passageway of each of the pair of doors is supported to be movable in the width direction of the passageway and rotatable around an axis along the vertical direction, and The end of each door on the outside of the passageway is supported so as to be movable in the longitudinal direction of the passageway and rotatable around an axis along the longitudinal direction.

A third feature of the present invention is that a linking means is provided for interlocking and connecting the pair of doors so that each of the doors moves integrally between a closed state and an open state.

Furthermore, a fourth feature of the present invention is that the linking means is an endless rotating body wound in the width direction of the passageway, and each of the pair of doors is attached to each of the pair of path portions of the endless rotating body. It lies in the points that are connected separately.

[For production]

The effect of the first feature is as follows.

That is, the passageway is opened and closed by a pair of left and right doors, and when the doors are closed, the pair of doors are aligned in the width direction of the passageway, and when they are open, they are positioned on the sides of the passageway along the lengthwise direction of the passageway. Become. In other words, there is no need to provide a special space outside the passageway for the door in the open state.

The pair of left and right doors that are opened and closed by sliding movement can be supported so that they will not open even if they are pressed in the longitudinal direction of the passage in the closed state, eliminating the need for a locking mechanism to fix them in the closed state. It is easy to handle.

The effect of the second feature is as follows.

That is, the ends of each of the pair of doors on the inside of the passage are supported so as to be movable in the width direction of the passage and rotatable around an axis along the vertical direction, and the ends of each of the pair of doors on the outside of the passage are However, since the left and right doors are slidably opened and closed by being supported so as to be movable in the longitudinal direction of the passageway and rotatable around an axis along the vertical direction, the structure of the door is simplified.

In other words, each of a pair of doors is divided into a plurality of door sections along the width direction of the door, and adjacent door sections are pivoted and connected around the vertical axis so that each door section can be bent freely. A structure in which a guided member attached to the guide member is supported movably along the rail is also conceivable. However, in the case of this structure, the structure of each field becomes complicated and the overall structure becomes expensive.

The operation of the third feature is as follows.

That is, a pair of doors are interlocked and connected by a linking means,
Since the pair of doors is moved integrally from a closed state to a closed state, the trouble of opening and closing each pair of doors separately is eliminated, and the pair of doors can be opened and closed at once.

The effect of the fourth feature is as follows.

That is, when a pair of doors are linked together by a linking means so as to open and close at once, the linking means is constructed using a single endless rotating body, so it is possible to simplify the structure of the linking means. be advantageous to

〔Example〕

Hereinafter, a case where the present invention is applied to a gate that opens and closes a passage on a weighing platform used to measure the weight of a cow as a walking animal will be described based on the drawings.

As shown in Fig. 5, a weighing means (S) whose main part is a weighing platform (1) is installed in the walking path where cows are accustomed to walking, such as between the livestock pen and the pasture. , the cow is on the weighing platform (1
) The cow's weight was to be measured while walking on it.

The walking path is equipped with fences (2) on both sides, and the shelf portions (2a) of the fences (2) located on both sides of the weighing platform (1) are connected to the weighing platform (1). ) is adapted to function as a restrictor to prevent laterally outward movement of the cow so as to cause it to walk along a straight or substantially straight path. The interval between the left and right shelf portions (2a) is made slightly larger than the width of the cow, so that the above-mentioned regulating action can be performed accurately.

The length of the walking path of the cow on the weighing platform (1) is determined to be long enough for the cow to take at least a walk (for example 3 to 6 steps) with its entire load on the weighing platform.

Incidentally, in this example, the total length of the weighing platform (1) is 3 m, the width is 80 cm, and the distance between the legs of the cow, whose total length is approximately 2 m1, is approximately 1.5 m. Then, the weighing platform (
The width of 1) corresponds to 1.1 to 1.5 times the width of a cow.

In addition, the entrance and exit of the weighing platform (1) are
G) It is designed to be opened and closed by.

The weighing platform (1) includes a platform body (1a) and a platform body (1a).
The output signal of the load cell (1b) is sent to the measurement processing unit (1b) as a weighing value. H). By the way,
The output signals of the four load cells (1b) are added and output to the measurement processing section (H).

Furthermore, a rubber mat (1c) as a collision-absorbing elastic material layer is laid on the upper surface of the stand main body (1a) to reduce the impact when the cow puts her foot down.

In addition, a tag (3) that transmits radio signals to separate the weighing medium is hung around the neck of the weighing medium, and a tag (3) that transmits information transmitted from the tag (3) is hung next to the weighing platform (1). A tag recognition means (4) consisting of a receiving antenna or the like is provided, and the information received by the tag recognition means (4) is also input manually to a measurement processing section (H). In other words, the measurement processing section (H
) is designed to identify the -head cow out of a plurality of cows, and measure the weight 1 of the walking cow along with the identifying information.

As shown in FIG. 6, the measurement processing section (H) includes a manual means (5) for receiving and receiving an electric signal indicating a weighed value sent from the scale 1 means (S), and a stationary single value The system is comprised of a central control device (6) that determines the value of bases, and an output means (7) that outputs the determined stationary base weight value.

The input means (5) includes an amplifier (5A) for amplifying the analog electrical signal from the weighing means (S), a low-pass filter (5B) for smoothing the output of the amplifier, and a smoothed signal for a predetermined sampling period. But “A” is quantized.
/D converter (5C).

The central control device (6) has a memo 'J (
6A), gait periodicity evaluation means (6B) that calculates the gait periodicity from the time series data, and valid data section setting means (6C) that sets a valid data section from the time series based on the gait periodicity. ), and calculation means (6D) for calculating the static weight value of the running animal from the time-series data in the valid data section, and is configured with a microcomputer as its main part.

In this embodiment, the output means (7) is a CRT (7
A) and printer (7B) are used.

Next, the procedure for determining the static weight of a cow walking on the weighing platform (1) will be explained.

FIG. 7 is a graph of the amplifier output of an analog signal indicating the weight value sent from the load cell (1b) as the cow walks on the weighing platform (1). In this graph, the area indicated by a is where only the front legs of the walking animal are on the weighing platform (1
), the area marked b is the state where the cow's entire weight is on the weighing platform (1), and the area marked C is the state where only the cow's hind legs are on the weighing platform (1). It is in a state of

A signal obtained by applying a low-pass filter to this amplifier output is shown in FIG.

Furthermore, FIG. 9 is an enlarged view of the area already shown above, and from this view it can be understood how the analog weighing value signal is sampled and quantized.

When the quantized weighing value data (hereinafter simply referred to as weighing value data) becomes larger than a set value (K) that is slightly larger than the weight of the weighing platform (1a), the cow gets on the weighing platform (1a). As a starting point, the weighing value data is sequentially stored in the memory (6A) as a sampling series, and the storage is such that when the scale 1 value data becomes smaller than the setting 1 (K), the cow gets off the platform body (1a). It ends as a result.

Next, the gait periodicity evaluation means (6B) calculates the maximum value: Wmax from the stored sampling data, and from this calculates a data group in a predetermined range, in this example, having a value of 90% or more of the maximum value. The data group is regarded as a weighing value data group in a state where the entire weight of the cow is placed on the platform body (1a).

From this weighing value data group, we further use the gait periodicity evaluation method (
6B) evaluates its gait periodicity by examining its maximum value. In the case shown in FIG. 9, the local maximum value is W
l, W8. Wl5. W23. There will be five W29s.

Next, the valid data interval setting means (6C) sets a valid data interval T, starting from the time when the first local maximum value W1 appears and ending at the time when the plurality of times, in this case, the fourth maximum value W23 appears. It turns out.

The sampling data within the valid data section thus set is averaged by the calculation means (6D), and the static weight value of the cow running on the platform body (1a) is calculated. In this average calculation, preferably a weighted average calculation method using an appropriate window function, such as a Hamming window, is used, thereby suppressing inconveniences associated with data extraction.

Next, the gate (G) will be explained. However, since the inlet side and the outlet side have similar configurations, one side will be explained below as a representative.
