Furthermore, an exit shute 3 is linearly provided so as to be located on the extended line of the linear walking channel on the weighing apparatus 2, ensuring the cows after completion of their weighing to readily leave said weighing apparatus.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a walkable animal guideway used to guide animals such as cows, sheep, horses, etc. one by one from among many animals. In particular, it relates to one in which the width of the passage is slightly wider than the width of one target animal due to the regulating bodies on both sides.

[Conventional technology]

For example, when weighing or inspecting herd animals,
A guideway is needed to guide the animals one by one from the herd and place them on a weighing platform, or drive them into a space for testing. This guideway is formed by installing fence-like regulating bodies along both sides of the path that the animal passes at intervals large enough for one target animal to pass through, and when viewed from the top, it looks like a straight line. Common.

[Problem to be solved by the invention]

The width of the guideway is set to be wide enough to guide all the animals to be guided. As a supplement, the regulating bodies are provided at intervals slightly wider than the width of the animal that is considered to be the thickest among the animals to be guided. However, the size of animals varies depending on their age, growth status, and species. Even within the same species, there are animals with wide and narrow widths. Therefore, when the width is relatively narrow and an animal is to be guided, if the animal's side becomes clogged, a considerable gap is created between the animal and the regulating body. If this gap is wide, subsequent animals may cut into the side and become stagnant, making it impossible to guide the animal smoothly. Furthermore, if the width of the following animal is narrow, it may end up lined up with the preceding animal, and two animals may be guided at the same time.

An object of the present invention is to prevent troubles caused by a following animal cutting into the side of a preceding animal.

[Means to solve the problem]

To achieve the above object, the first invention is characterized in that at least a portion of the guideway in the longitudinal direction is bent in plan view.

In the second invention, the bending angle of the bent portion is 80
It is characterized in that it is between 100 degrees and 100 degrees.

The third aspect of the invention is characterized in that a width adjustment means is provided for changing and adjusting the width of the bent portion.

The fourth aspect of the invention is characterized in that a restraining space for weighing or testing, through which an ambulatory animal walks, is connected to the entrance side.

[Operation of the first invention] When the target animal that has been guided along the guide path reaches a curved part, it has to bend according to the curve. When an animal makes a turn, it must walk with its body diagonal to the guideway, and for this purpose it utilizes the gap created between its body and the regulating body. In this case, even small animals can utilize most of the space by tilting their bodies. Therefore, two animals cannot bend at the same time. If two animals are following, the following animal waits until the leading animal has finished turning and then begins turning.

In other words, since gaps are used when making a turn, the following animal cannot cut into the gap of the leading animal at the curved part of the taxiway, and if the following animal cuts in, the leading animal will not be able to turn. The two animals are separated one behind the other, as the following animal cannot move forward until it is finished.

In addition, animals walk normally in a straight line, but they walk slowly in a curved area, so even if there are multiple animals following each other, the distance between the animals is adjusted to an appropriate distance at the end of the bend.

[Effects of the first invention] It is possible to prevent troubles such as a following animal cutting into the gap between the preceding animals, and even when a plurality of animals are guided one after another, it is possible to adjust the intervals to be appropriate. Therefore, it becomes possible to smoothly guide the weighing device to the entrance. This becomes more effective by providing a plurality of bent portions in the guide path.

[Operations and effects of the second invention] If the bending angle is too small, the gap will not be fully utilized when bending, which may result in a following animal cutting in. On the other hand, if the bending angle is too large, the animal will have difficulty bending, making it difficult to guide the animal smoothly. It has been established by the Applicant that a bending angle of 80 degrees to 100 degrees allows even small animals to fully utilize the gap and turn quickly.

[Operations and effects of the third invention] Body length and width vary depending on the animal.

Animals with long bodies or wide bodies are easier to separate, but they require leverage to bend. In this case, if the lateral width of the bent portion is adjusted to be wide by the width adjustment means, the bending can be quickly performed. Also, animals with short body length or narrow width tend to bend easily, but they also tend to create gaps. In this case, if the width of the bent portion is adjusted narrowly by the width adjustment means, the interruption can be reliably prevented. In particular, by providing a width-limiting means at the bend, which is the point where two animals are separated, a sufficient separation effect can be expected without having to make it so large-scale as to change the interval between the regulating devices.

[Operations and effects of the fourth invention] If the animals guided along this guide path are guided to the entrance of the restraint space for weighing and testing, even if a large number of animals are in a group, they can be quickly weighed and tested. can do.

EMBODIMENT OF THE INVENTION Hereinafter, the case where the Example of this invention is applied to the weighing of a cow is demonstrated based on drawing.

As shown in FIG. 1, a cattle weight measuring device is installed in the middle of a walking path where cattle are accustomed to walking, such as between a livestock pen and a pasture.

This weight measuring device is an inlet shoe for guiding cattle) (1)
(corresponding to the guideway in the claims), and a weighing device (2
) and an exit chute (3) for guiding the cow, and as the cow walks past the weighing device (2), the static weight value of the cow is measured. It is designed to be measured.

The entrance chute (1) and the exit chute (3) are fences (LA) and (3A) (framed by pipe frames).
The system is constructed by providing the regulators (corresponding to the regulating bodies in the claims) on both the left and right sides of the passage at intervals that allow one cow to pass through, so that the cow can walk safely while keeping an eye on its surroundings. be.

The entrance seat (1) is for guiding cattle one by one from the herd gathered in the holding area to the weighing machine (2). The adjacent part (1a) is bent to form a substantially right angle, and the weighing device (
2). In other words, by bending the walking path of the cows, it is possible to prevent two cows from entering the weighing machine (2) at the same time, or to prevent a following cow from cutting in from the side of the preceding cow. In addition, the bent part (1
The outer booklet (1A) of a) is formed into an arc shape to facilitate the cow to change the direction of her head.

The exit chute (3) is provided in a straight line so as to be located as an extension of the linear walking path on the weighing device (2), so that the cow can easily exit after being weighed.

As shown in FIG. 2, the weighing section (S) sequentially captures the weighing data of guided cattle while walking on the scale (2), and calculates the weight of the cattle from the captured weighing data. A measurement processing unit (H) is provided to calculate the static weight value of the weighing device (2), and a measurement processing unit (H) is provided on the inlet side and the outlet side of the weighing device (2), respectively.
), and furthermore, fences (4) are provided on both sides of the scale (2) to regulate the walking direction of the cow so that the cow walks along a straight path on the scale. is provided.

By the way, the body length of the weighing device (2) is set to 3 m so that the cow can walk (for example, 3 to 6) with its entire body on it, and the distance between the left and right fences (4) is set to the length of one cow. The distance should be set so that a cow can pass through (for example, 70 to 80 cm).

Next, the weighing device (2) will be explained in detail based mainly on FIGS. 3 to 5.

The weighing device (2) is assembled to a pair of front and rear plate-shaped bases (5) installed on the inlet side and the outlet side, and includes a rectangular measurement object mounting part (2A) and its mounting part (2A).
It is equipped with four load detection parts (2B) arranged so as to receive and stop each of the squares of two people separately. The load detection section (2B) consists of a plate-shaped load cell receiver (6) and a load cell (7) fixed to the load cell receiver (6) with a bolt (see FIG. 3).

The measurement object mounting section (for two people) includes a pair of elongated frames (8) along the long side direction, and four parts divided along the long side direction.
each of the frame bodies (8) is detachably connected to the load detection part (2B), and each of the frame bodies (9) is connected to the pair of frame bodies (9). (8) and is removably placed on it (see Fig. 4).

To explain each part, the pair of bases (5)
is fixed to the road surface with anchor bolts (10). The load cell receivers (6) are bolted to both left and right ends of these bases (5). Each load cell (7) has a service pin (
11) is inserted in a removable manner, and the elongated frame (8) is removably fitted into the head of the pin (11). Incidentally, side frames (12) are installed at both front and rear ends of the pair of elongated frames (8) to connect them.

When fitting the elongated frame body (8) to the service pin (11), a rubber pad) (
13) and a washer (14) are stacked in two layers, and the head of the pin (11) is inserted into the hole (15) passing through these, thereby reducing the high frequency vibrations generated when the cow walks. (See Figure 5).

The upper surface of the mounting plate (9) is made of rubber pine (1
6) is attached by adhesive. Each mounting board (9)
(pine trees located on the entrance and exit sides) (1
6) is extended to the inlet side or outlet side, and its extension part (16
a) is a tilting table (
17). This is designed to prevent mud and stones from entering the gap between the scale (2) and the ramp (17) (see Figure 2). Further, an angle member (18) is attached to the lower surface of the mounting plate (9), which serves both for positioning and reinforcement by contacting with the elongated frame (8).

In this way, the weighing device (2) can be divided into the measurement object mounting section (2A) and the load detection section (2B), and the measurement object mounting section (2 people) is connected to the pair of elongated frames (8). and four mounting plates (
9) Because it can be divided into two parts, it is possible to handle individual items that are extremely heavy compared to the overall weight.
The transportation and installation work can be carried out easily even by one person.

Next, each of the gates (Gl) and (G2) will be explained based on FIGS. 6 to 8.

However, since both games) (Gl) and (G2) have basically the same structure, I will explain using Jinrogame (Gl) as a representative, and add explanations for Outerrogame) (G2) as needed.

The human logo game (Gl) consists of a gate-shaped frame (19), a pair of left and right doors (20) that open and close in a sliding manner, and a door opening/closing mechanism (21) that opens and closes the doors (20). The lower end flanges of the portal frame (19) are fixed to both ends of the base (5) with bolts.

The door (20) is formed into a horizontal lattice shape with a plurality of horizontal vibrator frames (20a) in order to improve the cow's visibility and prevent the cow from feeling uneasy, and the portion corresponding to the cow's feet has a , a board (20b) is pasted so as not to attract the attention of the cows. Furthermore, in order to make the pot lighter and reduce costs, the lower part of the plate (20b) is omitted to leave a gap (
(See Figure 6).

Brackets (22) are provided at both left and right ends of the upper portion (19a) of the portal frame (19), and a stopper (23) is provided at the center of the horizontal frame portion (19a). These brackets (22) and stoppers (23)
) is supported by a round bar-shaped upper slide rail (24) (see FIG. 7). This upper slide rail (
24), bosses (25) welded to the left and right upper portions of the door (20) are slidably fitted on the outside (see FIG. 8).

On the other hand, a pair of left and right vertical frame portions (19b) of the portal frame (19) are provided with locking pieces (26) that slidably lock the lower edge of the door (20). Therefore, the door (20) is supported in a suspended state so as to be freely slidable.

Further, as shown in FIG. 7, the horizontal frame portion (1
A sprocket (27) rotatable about a vertical axis is provided on each of the left and right ends of the sprocket (27), and a chain (28) is wound around these sprockets (27). Then, the pair of path portions of the chain (28) are separately connected to the bosses (25) on the inner side of the left and right doors (20), and as the chain (28) rotates, the left and right doors (20) ( 20) are configured to slide in opposite directions, so that the left and right doors (20) can be opened and closed at the same time.

The door opening/closing mechanism (21) includes a first operating lever (29) as an opening/closing operating tool provided on the vertical frame portion (19b) of the gate-shaped frame (19) so as to be able to swing vertically, and this first operating lever. A swinging arm (30) attached to the support shaft (29a) of (29), and an erection connection between this swinging arm (30) and a boss (25) on the inside of the left door (20). It consists of a push/pull link (31).

Then, when the first operating lever (29) is manually rocked downward, the swing arm (30) swings outward and the push/pull link (31) is pulled outward to the left. (2
0) is now open. Of course, as described above, the left and right doors (20) are interlocked and connected so that they slide in opposite directions at the same time, so the right door (20) is also opened. In addition, the inner boss (25) to which the push/pull link (31) is connected and the horizontal frame portion (
A spring (32) that pulls and biases the door (20) toward the closing side is interposed between the door (19a) and the left and right doors (20) when the first operating lever (29) is released. It is designed to return to the closed position regulated by (23).

Since the exit gate (G2) has a front-back symmetrical structure with that of the human log game (Gl), a detailed explanation of its structure will be omitted. However, the second operation lever (33) as an opening/closing operation tool for operating this output game (G2) is provided on the entrance side of the weighing device (2) together with the first operation lever (29). That is, the second operating lever (3
The support shaft (33a) of 3) is connected to the portal frame (19) of the entering log game) (Gυ's portal frame (19) and the portal frame (19) of the exit log game) (G2).
34), and a second operating lever (33) is attached to the support shaft (33a) near the artificial gate (G) (see FIG. 2).

Therefore, the operator can open and close both the gates (G,) and (G2) while remaining on the inlet side of the weighing device (2).

Next, a description will be given of a configuration in which a cow is made to walk along a linear walking path on the scale (2).

As mentioned above, fences (4) are provided on both the left and right sides of the weighing device (2), and a width fence (3) is provided below these fences (4).
8) is provided. The fence (4) is provided to restrict lateral movement of the cow's body, and the width fence (38) is provided to restrict lateral movement of the cow's legs.

As shown in FIG. 2, the fence (4) has a horizontal lattice shape in which front and rear vertical pipe frames (35a) are connected by four horizontal pipe frames (35b) arranged in the vertical direction, The vertical frame part (19b) of the portal frame (19) of the entry gate (G,), and the vertical frame part (34b) of the portal frame (34) of the exit gate (G2),
It is fixed to each of the central pillars (37) located between them using 0-shaped bolts (36). In this way, by connecting the population gate (C+) and the exit game (G2) through the fence (4), they are made into an integrated structure, thereby increasing their installation strength.

By the way, if the walking direction of the cow is restricted only by 1 (4) above, there is a risk that the calf etc. will change direction unnecessarily, and the body part of the cow will be more likely to come into contact with the fence (4). This contact tends to cause errors in the weighed value. For this reason, the above-mentioned side fence (38) is provided to avoid these inconveniences. The width fence (38) is
A rectangular loop formed by a pipe frame is connected with a plurality of reinforcing pipe frames (41) arranged in the vertical direction to form a framework, and a board (38a) is pasted on the entire inside of the frame, and a fence ( It is suspended from the horizontal pipe frame (35b) at the bottom of 4) so as to be able to swing freely. By adjusting the swing, the left and right side fences (38
) can be adjusted to suit the size of the cow. Specifically, as shown in FIG. 4, a support frame (39) is fixed to the central column (37) along the front-rear direction, and pin receivers are attached to brackets at both ends of the support frame (39). (40) is attached. In addition, the reinforced pipe frame (
Plate-shaped adjustment fittings (42) are pivotally attached to the front and back of the lower end of the fittings (41). And the pin holder is a bracket)
(40) and the adjustment fitting (42) are connected with pins to restrict the swinging of the fence (38), and the adjustment fitting (42) has a large number of pin holes (42a). It is perforated. Therefore, when adjusting the interval between the left and right side fences (38), the pin holes (42) used for connection must be adjusted.
This can be easily done by changing a).

Incidentally, the width fence (38) can be used to substantially change the passage for cattle without changing the width of the fence (4), but even if it is narrowed, it does not approach from both sides like a normal fence. This has the advantage of not causing anxiety to the cows as there is no pressure from the cows.

As shown in FIG. 9, a stand (43) is erected near the entrance side of the weighing device (2).

The front-open, box-shaped casing (44) fixed to the top of the stand (43) has an instrument box (B) that houses the measurement processing unit (H) that can be tilted back and forth using two bolts. Possibly supported. Further, a printer mounting stand (45) is provided on the side of the casing (44), and a printer (46) for printing the cow's identification number and determined static weight value is placed on this stand. ing.

This printer mounting stand (45) is swingably provided via a hinge (47), and when not in use, it can be swung upwards and placed over the top of the casing (44) for compact storage. It's Nishide.

On the front of the instrument box (B), there is a first display section (48
) and the second display section (49), a numeric keypad (50) for data input, ON/OFF keys (51) and (52) for commanding the start and end of weighing, and commands for printing on the printer (46). Various keys such as a print key (53) are provided. Further, a buzzer (54) is provided in the instrument box (B). The first display section (48) displays the identification number of the cow input using the numeric keypad (50), the weighing value data read at any time, etc.
The calculated static weight value of the cow is displayed on the display section (49).

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

Cows are guided to the artificial chute (1) and enter the entrance gate (GO).
When you get to the front of , enter the cow's identification number on the numeric keypad (
50) Press manually. When the manual operation is finished, operate the first operating lever (29) to release the population game) (G,),
Place the cow on the scale (2).

When the cow gets on the scale (2), the GO is closed. When the static weight value is determined by the measurement processing section (S), the buzzer (54) is activated to notify the end of weighing. .Then, open the weighing machine (G2) to remove the cow from the scale (2), and press the print key (53) to display the static weight value displayed on the second display (49) along with the cow's identification number. Make the printer (46) print.

Next, the measurement processing section (H) will be explained in detail.

As shown in FIG. 1O, this measurement process B(H) includes an input means (55) for receiving and receiving a weight value signal (analog electrical signal) obtained by adding the detection signals of the four load cells (7); The receiver consists of a central control unit (56) that sequentially captures and stores the taken weighing value signals as time-series weighing value data to obtain a static weight value.

The human power means (55) includes an amplifier (55^) that amplifies the weighed value signal, a low-pass filter (55B) that smoothes the output of this amplifier, and quantizes the smoothed signal at a predetermined sampling time. A/D converter (
55C).

The central control device (56) stores time-series weight value data of sampled weight values for a certain period of time. J (56A), a gait periodicity evaluation means (56B) that calculates gait periodicity from the time-series weighed value data, and sets a valid data section (T) from the time-series weighed value data based on the gait periodicity. It consists of a valid data interval setting means (56C) and a calculation means (56D) for calculating the static weight value of a walking animal from the time-series weighing value data in the valid data interval (T). It is organized as a department.

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

Figure 11 shows that as the cow walks on the scale (2),
It is a graph of the amplifier output of the analog signal indicating the weighed value sent from the load cell (7). In this graph, the area indicated by a indicates that only the forepaws of the walking animal are on the scale (2
), the region indicated by b is the state where the whole cow 1 is on the scale (2), and the region indicated by C is the state where only the cow's hind legs are on the scale (2). It is in a riding state.

The output of this amplifier is passed through a low-pass filter (55B) and becomes a smoothed signal as shown in FIG. 1st
FIG. 3 is an enlarged view of the region already shown above, and from this figure it can be understood how the analog weighing value signal is sampled and quantized.

After weighing has started, when the quantized weight 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 scale (2), the cow is weighed. Assuming that the weighing device (2) has started to be loaded, the weighed value data is sequentially stored in the memory (56A) as a sampling series. This memo! J (56A), the sample data interval (T
o).

Next, the gait periodicity evaluation means (56B) calculates the maximum value: Wmax from the sampling data stored in the memory (56A), and 90% of this maximum value.
The data group with the above values indicates that the total weight load of the cow is measured on the scale (
2) It is regarded as a group of weighing value data while riding on the
Identified as a weighing value data group. In addition, in this example,
We multiplied by 0.9, but the value (n) to be multiplied is:
Numbers greater than 0.8 and less than 1 can be used.

Furthermore, the gait periodicity evaluation means (56B) evaluates the gait periodicity from this weighed value data group by examining its maximum value. In the case shown in FIG. 13, the local maximum values are Wl, W8. Wl5゜W23. There will be five W29s.

Next, the valid data interval setting means (56C) sets the time point at which the first local maximum value W1 appears as the starting point, and sets the
Here, a valid data section (T) is set with the end point at the time when the fourth maximum value W23 appears.

However, in setting this effective data interval (T), how many gait cycle peaks are included can be set in advance depending on the type of walking animal, the natural frequency of the weighing device (2), etc.

The sampling data within the effective data interval (T) thus set is averaged by the calculation means (560), and the static weight value of the cow walking on the scale (2) is calculated. By this measurement, an animal weighing, for example, 1000 kg can be detected with accuracy within an error of 1 kg.

[Another example]

As shown in FIG. 14, three bent portions (1a) are successively provided in the middle of the population siz −+−(t). The bending angles of the upper and lower side bending portions (1a) in the direction of travel are each 125 degrees, and the bending angle of the central bending portion (1a) is set to 90 degrees. In addition, the central bent part (
In 1a), a width door (57), which is an example of width width means, is swingably provided.

By swinging and adjusting the width door (57), the distance between the paths can be substantially changed without changing the distance between the fences (1A). And this width door (
57) Although it is a rigid body, it is constructed in such a way that when it receives an external force above a certain level from the cow, it retreats inward to prevent injury to the cow.

As shown in FIG. 15, the width door (57) may be provided so as to swing backwardly.

In addition, the width door (57) should be constructed so that it can be evacuated by external force (
However, the same effect can be achieved by making the material itself elastic.

Furthermore, on the upper side of the width door (57), add the width of the cow.
A light sensor for detection may be provided, and the width door (57) may be automatically adjusted based on the detection result of the light sensor.

[Other alternative embodiments]

The shape of the above-mentioned population (1) can be changed in various ways. For example, as shown in Figure 16, the entrance chute (
There is another bent part (1a) in the guideway part located on the upper side than the bent part (1a) near the scale (2) in 1).
may be provided so that the cows are separated at a plurality of bends. In this case, the length of the straight line sandwiched between the two bent portions is preferably slightly shorter than the body length of the cow.

Further, as shown in FIG. 17, the inlet chute (1) may be bent in an arc shape.

Furthermore, the bending portion (1a) provided in the portion close to the weighing device (2) of the population shift x-) (1) and the weighing device (1)
) A straight section may be added between the scale and the curved section, and the cow that has turned the bend may pass through the straight section once and then step on the weighing device (2).

[Application example]

In the case of a quadrupedal animal with a thick body such as a cow, due to its body shape, large gaps tend to form at the top and bottom of the fence (1A) of the population (A -) (t), and the following animals can move their heads close to that of the preceding cow. It cuts into the upper or lower side of the armpit. In that case, instead of using a straight fence (1A), a curved fence with a middle portion projecting outward may be provided so that the cross section is oval. By doing so, the gap between it and the fence (1A) can be made as small as possible.

Further, the regulating body is not limited to the fence (1A), but may be something like a wall.

In this embodiment, cows are weighed, but other animals such as cows, horses, and sheep may be weighed. In addition, the population chute (1) described above can be used not only as a guideway to the weighing device (2), but also as a guideway to a restricted space for testing or medical purposes for body temperature measurement, body length measurement, and diagnosis. is also possible.
