DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tow line for towing a milking machine in a dairy cattle barn, and more particularly to an apparatus for changing its direction.

[0002]

2. Description of the Related Art Hitherto, in a milking operation of a dairy cow, when a milking machine is changed from a cow to a cow, an operator has to carry and move the milking machine one by one, which requires a great deal of labor.

By the way, the present inventor has previously described Japanese Patent Application No. 8-1.
No. 72754 proposes a traction device of this kind.
This is tow the cow itself, but the gist is to solve the conventional problem by arranging the guide rail for towing the cow over 160 cm above the floor. Therefore, the present inventor has conceived of arranging such a guide rail and pulling and moving the milking machine also in the work of transporting the milking machine. That is, a guide rail 11 using an existing I-type steel or H-type steel is erected in a livestock barn, and a milking machine M is attached to a traction runner 12 that slides on the guide rail 11, thereby saving labor for transporting the milking machine. (See FIG. 7).
reference).

[0004]

However, when the milking machine is turned on the guide rail (for example, when the milking machine is pulled into an enclosure perpendicular to the moving path), the milking machine is replaced with another tow runner. Alternatively, the tow runner must be once detached from the guide rail and re-mounted on another guide rail, resulting in a problem that the operation becomes complicated. The present invention has been made in view of the above problems, and an object of the present invention is to provide a directional change device in a traction line of a milking machine that can easily perform a directional change in traction work of the milking machine. is there.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 10 shown in FIG. 7 denotes a tow line for towing and moving a milking machine M in a dairy cattle stall, and a vertically symmetric flange 1 through a central web 11a.
A guide rail 11 using an existing I-type steel or H-type steel having 1b is provided in an elevated manner in accordance with a moving route for moving cows. Specifically, the height up to the guide rail 11 is about 160 cm or more above the floor, preferably from 180 cm to 20 cm.
It is suspended at a height of about 0 cm by a support beam 9 arranged on the ceiling side, and a tow runner 12 that slides and moves on the guide rail 11 is mounted. As shown in FIGS. 5 to 7, the tow runner 12 is a column 1 extending downward.
Arm rods 12b and 12c are provided at two places above and below 2a.
And the cylinder 13 of the milking machine M
The hook 14 attached to the arm rod 12b can be hooked on the arm rod 12b.

A metal support frame 15 is provided at the upper end of the towing runner 12, and the diameter of the support frame 15 is smaller than the width of the support frame 15 in a state in which both sides of the support frame 15 face each other. A pair of support pulleys 16 are rotatably supported on a shaft, and roll on the upper surface of the lower flange 11 b of the guide rail 11. Further, a torgue clamp 17 is attached to the support 12a of the towing runner 12, and a steel wire 18 vertically connected to the torch clamp 17 is penetrated from the bottom frame of the support frame 15 so as to be movable up and down. The upper end surface of the steel wire 18 presses the lower surface of the flange 11b of the guide rail 11, so that the towing runner 12 can be temporarily fixed on the guide rail 11.

[0009] The direction changing device T of the present invention comprises a traction line 1
At 0, a plurality of guide rails 11 are provided at a branch point. As shown in FIGS. 1 to 3, for example, a case where four guide rails 11 are orthogonally branched in four directions will be described. The direction changing device T includes a cover 1 having a substantially cylindrical shape, and a rotating body 2 rotatably mounted in the cover 1 in a horizontal direction.
It is composed of The cover 1 is provided with windows 1a, 1b, 1c and 1d on four sides of its peripheral wall, and guide plates 3 for joining with the respective guide rails 11 are externally provided from the windows 1a, 1b, 1c and 1d. It is attached to extend.

The rotating body 2 is provided with a vertical rotating shaft 2a at the center, and four engaging rail pieces 5 to which the towing runner 12 is engaged by piers 4 arranged in a cross shape around four sides. The support pulley 16 fits into a gap between each engagement rail piece 5 and a locking piece 2b provided at the lower end of the rotating shaft 2a, so that the towing runner 12 can be locked. The support plate 8 supporting the rotating body 2 on the cover 1 at the upper end accommodates ball-shaped stoppers 6 at two arbitrary positions corresponding to the engagement rail pieces 5 respectively. On the top surface of the top plate of the cover 1, four recesses 7 are formed at positions corresponding to the engagement rail pieces 5, similarly to the two ball-shaped stoppers 6. Stopper 6
The rotation of the rotator 2 can be restricted by dropping the rotation. The guide plate 3 and the engagement rail piece 5 connected to each guide rail 11 have a flange at the lower end similar to the flange 11b of the guide rail 11, so that the towing runner 12 can enter the guide rail 11 continuously. Have been able to.

Next, the operation of this embodiment will be described with reference to FIG. As shown in FIGS. 4A and 4B,
When moving the tow runner 12 from the guide rail 11A to the guide rail 11B arranged at right angles to the guide rail 11A, first, the tow runner 12 is advanced into the direction change device T, and the support pulley 16 is connected to the engagement rail piece 5. The towing runner 12 is temporarily locked by being fitted into the gap with the locking piece 2b. In this state, if the tow runner 12 is rotated 90 ° together with the rotating body 2 to escape from the direction changing device T, the tow runner 12 moves on the guide rail 11B. In the present embodiment, the apparatus of the present invention is used for a line for moving a milking machine, but the configuration of the apparatus is not limited to such a purpose of use, for example, as in a meat processing line. In addition, the present invention can be applied to a production line in which a product is operated in a suspended state.

[0012]

As described above, according to the present invention, the rotating body disposed at the branch point of the towing line is provided with the vertical rotating shaft and the surroundings.
A plurality of engagement rail pieces with which the tow runner is engaged by the bridge pier, and a locking piece provided with a gap between the engagement rail pieces. The support pulley of the runner is fitted and locked in the gap between the engaging rail piece and the locking piece in the rotating body, and the towing runner together with the rotating body is rotated to a position where it can be engaged with the desired guide rail. As a result, there is an excellent effect that the direction can be easily changed in the moving operation of the milking machine.
