[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating walking animals, and more particularly, to separating a walking animal from a preceding and following walking animal on a part of a guideway for guiding a plurality of walking animals. The present invention relates to a separation device for a walking animal in which a separation unit for providing a single state is provided and an entrance gate is provided at an entrance of the separation unit.

[0002]

2. Description of the Related Art When weighing or testing a walking animal (for example, a walking animal such as a cow, a goat or a horse) forming a herd during breeding, one of the herds (a cow or the like) is processed. In the case of (1), the animal is counted as one, and hence a separate animal is required to guide the walking animal by one and put it on the weighing platform or drive it into the space for inspection. In such a separation device, conventionally, a separation section for separating one walking animal into a space where the processing is performed is provided in a part of a guideway for guiding a plurality of walking animals, and an entrance gate is provided at an entrance of the separation section. Was provided. And, the entrance gate, in order to perform the separation, in a state in which the preceding walking animal is in the separation unit, to prevent the subsequent walking animal from entering the separation unit, in that state, in a fully closed state, and The opening and closing operation is performed so that the preceding walking animal comes out of the separating section and the following walking animal enters the separating section so as to be fully opened so as to enter the separating section.

[0003]

However, in such a conventional separation apparatus, as described above, in order for a preceding walking animal to come out of the separation section and to allow a subsequent walking animal to enter the separation section. The entrance gate is fully opened, but when a plurality of subsequent walking animals run toward the separation unit while running in series, the traveling state of the walking animal is prevented because the entrance gate is fully opened. And there is a problem that the walking animal continuously runs through the separating section. Therefore, in such a case, the walking animals could not be separated one by one from the herd.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the problems of the conventional separation device as described above, and to always surely separate walking animals from a herd one by one. To provide a separation device capable of performing such separation.

[0005]

A first characteristic configuration of the walking animal separating apparatus according to the present invention is such that the entrance gate is swingably openable and closable, and blocks the front view of the walking animal in a fully closed state. Where, when there is a walking animal in the separation unit, the entrance gate is in a fully closed state, and when there is no walking animal in the separation unit, the entrance gate is opened halfway between fully closed and fully opened, There is provided an opening / closing operation means for allowing a walking animal to push and open the entrance gate in the middle of the fully closed state and the fully opened state so as to pass therethrough.

The second characteristic configuration is a preferred specific configuration for implementing the first characteristic configuration. The second characteristic configuration is provided in a state where the entrance gate is urged in the closing direction, and The opening and closing operation is provided at an exit portion in a state where the exit gate is swingably opened and closed and urged in a closing direction, and is formed so as to maintain a forward view of the walking animal in the fully closed state. Means for transmitting the rotational force of the former to the latter so as to open the entrance gate halfway between fully closed and fully opened with the opening rotation of the exit gate,
A ratchet mechanism comprising a combination of a ratchet gear and a ratchet pawl biased in a direction locked by the ratchet gear for permitting the opening rotation of the entrance gate while prohibiting the closing rotation thereof; Separation means for separating the ratchet claw from the ratchet gear based on the opening rotation from the halfway state with the walking animal passing,
And a separation releasing means for releasing the ratchet claw from the separated state based on the closing rotation by the urging after the entrance gate has passed through the walking animal.

A third characteristic configuration is a preferred specific configuration for implementing the first characteristic configuration, wherein the opening / closing operation means detects whether or not there is a walking animal in the separation section. Based on the detection means and the detection means detecting a state where no walking animal is present, the entrance gate is opened in the middle of the fully closed state and the fully opened state, and the opening rotation of the entrance gate is allowed, and And an actuator operable to set the entrance gate to a fully closed state based on detection of a state in which a walking animal is present by the detecting means.

A fourth characteristic configuration is that, in the first, second or third characteristic configuration, the separation section is constituted by a weighing table.

[0009]

According to the first characteristic configuration, when a walking animal is present in the separation section, the entrance gate is fully closed, so that a subsequent walking animal located in front of the entrance gate (ie, the separation section). Of the walking animal trying to enter the walking area), the walking animal is less motivated to move forward, and the walking animal is prevented from entering the separation section. When there is no walking animal in the separation section, the entrance gate is opened halfway between fully closed and fully opened. Therefore, the forward view of the following walking animal (that is, the walking animal trying to enter the separation unit) positioned in front thereof is opened, and the walking animal tries to enter the separation unit with a desire to move forward. Upon entry, the entrance gate in the middle of the fully closed and fully opened state is pushed open by the passage of the walking animal to be in the fully opened state, and the walking animal can enter the separation section. Moreover, the entrance gate is not opened in the fully opened state, but is opened in the middle of the fully closed state and the fully opened state.
While keeping the forward visibility of the following walking animal, the width of the taxiway where the walking animal moves forward is narrowed in front of the separating section. Therefore, even when a subsequent walking animal runs toward the separation unit while running, the running state of the walking animal can be prevented, and the walking animal can enter the separation unit in the walking state. .

According to the second characteristic configuration, the operation is performed in the following order. First, in a state where the preceding walking animal passes through the exit gate and exits from the separating section and there is no walking animal there, the entrance gate that appears with the opening rotation of the exit gate is fully closed and fully opened. Is opened by the ratchet mechanism. Therefore, the forward view of the following walking animal (that is, the walking animal trying to enter the separation unit) positioned in front thereof is opened, and the walking animal tries to enter the separation unit with a desire to move forward. At the time of entry, the entrance gate which is in the middle of the fully closed state and the fully opened state is allowed to open and rotate, so that the walking animal is pushed open by passing and becomes a fully open state, and the walking animal is moved to the separation section. You can enter. Furthermore, based on the opening rotation of the entrance gate accompanying the passage of the walking animal, the ratchet pawl is separated from the ratchet gear by the separation means, and the operation state of the ratchet mechanism is once released, and the entrance gate is It is closed and rotated by the bias. Further, based on the closing rotation of the entrance gate, the separation releasing means operates to release the separation state of the ratchet claw, and the release state (that is, the state in which the ratchet mechanism operates).
Is maintained and the entrance gate is closed and rotated to a fully closed state. In the fully-closed state, since the forward view of the following walking animal (that is, the walking animal trying to enter the separation section) positioned in front of the walking animal is obstructed, the walking animal loses willingness to move forward, and Animals are prevented from entering the separation. Even when the exit gate is in the fully closed state, the walking gate keeps the front view of the walking animal located in front of the exit gate (that is, the walking animal in the separation section). And move the walking animal forward to exit the detachment. During the forward movement, the outlet gate naturally opens, but the rotational force is transmitted to the entrance gate by the transmission means, whereby the entrance gate opens halfway between the fully closed state and the fully opened state. Further, the state in which the entrance gate is opened halfway between the fully closed state and the fully opened state is maintained by the ratchet mechanism, whereby the above-described initial state is reproduced.

According to a third characteristic configuration, the entrance gate is in a state between the fully closed state and the fully opened state by the actuator based on the fact that the detection means detects that no walking animal is present in the separation section. Opened to. Therefore, the forward view of the following walking animal (that is, the walking animal trying to enter the separation unit) positioned in front thereof is opened, and the walking animal tries to enter the separation unit with a desire to move forward. At the time of entry, the entrance gate which is in the middle of the fully closed state and the fully opened state is allowed to open and rotate, so that the walking animal is pushed open by passing and becomes a fully open state, and the walking animal is moved to the separation section. You can enter. Then, the entrance gate is fully closed by the actuator based on the detection of the presence of the walking animal in the separation unit by the detection unit when the walking animal enters the separation unit. Therefore, since the forward view of the following walking animal (that is, the walking animal trying to enter the separation unit) positioned in front of the walking animal is obstructed, the walking animal is discouraged from moving forward, and the separation unit of the walking animal is cut off. Entry is blocked.

According to the fourth characteristic configuration, since the separation section is constituted by the weighing table, the weighing can be performed while separating the walking animal as described above.

[0013]

As described above, according to the present invention, when a plurality of walking animals successively run toward the separation section as in the above-described conventional separation apparatus, the running state of the walking animal is prevented. A separation device that can surely solve the problem that the walking animal continuously runs through the separation section, and can always separate the walking animal from the herd one by one. Can be provided. In addition, according to the second characteristic configuration, even if a detecting means for detecting whether or not a walking animal is present in the separation unit and an actuator for opening and closing the entrance gate based on the detection information of the detecting means are not provided. As described above, in the state where the preceding walking animal is in the separation section, it prevents the following walking animal from entering the separation section, and causes the preceding walking animal to exit the separation section, and The separation can be performed by causing the following walking animal to enter the separation unit as the preceding walking animal exits the separation unit. Moreover, the separation can be automatically performed by mechanically setting those timings. Therefore, the walking animal can be easily separated at low cost.

Further, according to the third characteristic configuration, when the entrance gate is opened halfway between the fully closed state and the fully opened state, the control of changing the opening degree is extremely easy by electrically controlling the actuator. Therefore, it is extremely easy to change and control the opening degree of the entrance gate depending on the size of the walking animal, and the versatility is enhanced.

According to the fourth characteristic configuration, as described above, since the separation and the weighing can be performed as described above, the weighing operation indispensable for the breeding management of the walking animal can be easily performed at low cost.
