Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milking device transport path used for transporting milking devices such as milk claw, teat cup liner and milk tube in a livestock barn or other livestock barn.

[0002]

2. Description of the Related Art As the above-mentioned transport path, there is one having a structure as shown in FIGS. FIG. 8 is a partially cutaway front view, and FIG. 9 is a partially bottom view. Hereinafter, the conveying path of the milking device will be described.

In the conveying path of the milking apparatus, an L-shaped, T-shaped or cross-shaped track 30 is erected on a ceiling (not shown) of a barn. The track 30 is formed by connecting a plurality of rails 10 via a joint 20 having an L-shape, a T-shape, or a cross shape (in the drawing, a T-shape). The rail 10 is connected to the joint 20 with its end inserted into the joint 20.

[0004] A slider 40 for transporting the milking device is slidably accommodated in the track 30. Slider 40
Is made of a resin such as tetrafluoroethylene (trade name: Teflon) having a short columnar shape and a small friction coefficient. Then, the slider 40 is configured to be able to move smoothly in the track 30 formed by connecting the rail 10 formed of a steel plate or the like and the joint 20.

The rail 10 and the joint 20 have, for example, a C-shaped cross section. For example, the guide grooves 12 and 22 are continuously formed long in the longitudinal direction of the side wall of the rail 10 and the joint 20 facing downward, that is, in the center of the side wall of the rail 10 and the joint 20 facing the floor of the barn.
A hook 6 such as a hook for suspending a milking device suspended from the slider 40 is provided in the guide groove 12 or 22.
0 is movably inserted. The hook 62 has its body 62 inserted into the guide groove 12 or 22, and its tip hook 64 projects below the track 30.

As shown in FIG. 9, the width of the guide groove 22 of the joint is smaller than the width of the guide groove 12 of the rail. This is because when the slider 40 is moved inside the joint 20 that is largely bent in an L-shape, a T-shape, or the like, the sludge 40 is greatly inclined. If the width of the guide groove 22 of the joint is wide, the slider 4
0 enters the guide groove 22 of the joint, and the guide groove 22
Because it gets caught inside. This is because the slider 40 cannot be moved smoothly inside the joint 20. In contrast, rail guide groove 1
2 is formed so that the rail 10 has a linear shape or a nearly linear shape, and the slider 40
Without being caught in the guide groove 12 of the rail, the rail 1
This is because it always moves smoothly inside 0. Further, the wide groove width of the guide groove 12 of the rail is formed so that the hook 60 hanging from the slider 40 can be smoothly moved inside the guide groove 12 without being caught. That's why.

As shown in FIG. 9, the inner end face 22a facing the outer end of the guide groove 22 of the joint is cut into an oblique linear shape or an oblique arc shape (in the figure, the oblique linear shape). . The groove width of the outer end portion of the guide groove 22 of the joint is gradually increased outward to the lateral width of the guide groove 12 of the rail. And the guide grooves 2 of the joints having different groove widths
2 and the guide groove 12 of the rail,
0 is smoothly moved without being caught.

In the conveying path of the milking apparatus, a milk claw, a teat cup liner, and the like are attached to a tip end portion 64 of a hook 60 hung from a slider 40 housed in a track 30 provided on the ceiling of a barn. , A milking device such as a milk tube (not shown) can be suspended from the floor (not shown) of the barn. Then, the user pushes the milking device in the direction in which the track 30 is erected, and the slider 4 suspends the milking device via the hook 60.
0 can be moved in the trajectory 30. And
The milking device hung on the slider 40 via the hook 60 can be easily moved in the direction in which the track 30 is erected without lifting labor while being lifted from the floor of the barn.

[0009]

By the way, in the conveying path of the above milking apparatus, the track 3 between the end of the rail 10 inserted into the joint 20 and the joint 20 following the end is provided.
When the slider 40 is moved in the inner part of 0, the slider 40 is caught in the orbit 30 and
The slider 40 cannot be smoothly moved in the track 30. This phenomenon occurred remarkably when a heavy milking device was hung on the hook 60 hung from the slider 40.

[0010] This is because the rail 10
This is because a step 80 corresponding to the thickness of the side wall of the end of the rail 10 is formed at the boundary between the inner surface of the end and the inner surface of the joint 20 following the end, as shown in FIG. The slider 4 sliding on the inner surface of the track 30 on the step 80.
This is because 0 is caught. This slider 4
The catch of 0 was remarkably generated when the slider 40 moved from the inside of the joint 20 to the inside of the end of the rail 10.

In order to solve such a problem, means as shown in FIG. 11 has conventionally been taken. In this means, a plate-shaped spacer 50 is laid on the inner surface of the joint 20 following the end of the rail 10 inserted into the joint 20 by the thickness of the side wall of the end of the rail 10. The step 80 is prevented from being formed at the boundary between the inner surface of the end of the rail 10 and the inner surface of the joint 20 that follows.

However, even when this measure is taken, the slider 40 often gets caught on the boundary between the inner surface of the end of the rail 10 inserted into the joint 20 and the inner surface of the joint 20 that follows. .

This is caused by variations in the thickness of the spacer 50 laid on the inner surface of the joint 20 following the end of the rail 10 and the side wall of the end of the rail 10 and at the end of the rail 10 when the rail 10 is cut. The rail 10 may be turned or warped.
This is because a large or small step still occurs at the boundary between the inner surface of the end and the inner surface of the joint 20 that follows.

Further, when the slider 40 is moved inside the joint 20 which is largely bent in an L-shape, a T-shape or the like, the slider 40 is greatly inclined and a part of the slider 40 is , Or the hook 60 hung down from the slider 40 was strongly pressed against the opposing inner end face of the guide groove 22 of the joint. The slider 40 and the latch 60 are connected to the joint 2.
A large frictional resistance was received from the inner side surface of the No. 0 and the opposing inner end surface of the guide groove 22 of the joint. And, the slider 40,
The inside portion of the joint 20 bent in an L shape, a T shape, or the like could not be moved smoothly. At the same time, due to the large frictional resistance that the slider 40 and the latch 60 receive from the inner side surface of the joint 20 and the inner end face of the joint groove 22 facing the joint 20, the slider 40 and the latch 60 were quickly worn.

The present invention can solve such a problem.
It is intended to provide a transport path for milking equipment.

[0016]

In order to achieve the above object, the conveying path of the milking apparatus of the present invention is a track formed by connecting a plurality of rails via joints, and the rail ends are connected to the rails. A track inserted into the joint and connected to the joint is erected on the ceiling of the barn, and a slider for conveying a milking device is slidably accommodated in the track, and the rail and the longitudinal direction of the joint are accommodated. Hooks for suspending milking equipment suspended from the slider in guide grooves that are continuously opened to the guide groove, the guide grooves being formed so that the width of the guide groove of the joint is smaller than the width of the guide groove of the rail. In the conveyance path of the milking device in which the tool is movably inserted, the opposing inner end face of the guide groove of the joint and the inner side face of the joint following the end face are covered with a smooth resin layer, and Guide of the rail end inserted inside the joint At least a portion of the surface portion of the resin layer that covers the inner side surface of the joint exposed to the inside of the joint is inclined downward toward the outside of the joint, and the rail end that follows the inclined surface portion of the resin layer.

In the conveying path of the milking apparatus,
At least a part of the surface portion of the resin layer covering the inner side surface of the joint exposed inside the guide groove at the end of the rail inserted into the joint is inclined downward toward the outside of the joint. Then, the inner end of the surface portion of the resin layer exposed inside the guide groove of the rail following the inclined surface portion of the resin layer is positioned above the inner side surface of the rail end. At the same time, the outer end portion of the surface portion of the resin layer exposed inside the guide groove of the rail following the inclined surface portion of the resin layer is located below the inner side surface of the rail end portion. Therefore, the middle part of the surface part of the resin layer inclined downward toward the outside and the middle part of the inner side surface of the rail end can be crossed in a V-shape when viewed from the lateral direction. . Then, the middle part of the surface portion of the resin layer inclined downward and the middle part of the inner side surface of the rail end can be smoothly connected without any step. Then, through the surface portion of the resin layer inclined downward, the inner surface of the rail end portion and the surface portion of the resin layer exposed inside the guide groove of the rail positioned above the inner surface of the rail end portion. The bottom surface of the slider can be slid smoothly between the inner end portion and the bottom surface of the slider without being caught on the rail edge or the like. And the inner part between the rail end and the joint, the slider, without getting caught,
It can be moved smoothly.

In the conveying path of the milking apparatus of the present invention, the bottom surface of the slider is formed in the same shape as a part of a spherical surface or a partial side surface of a cone, and the bottom surface of the slider faces the guide groove of the joint. The inner edge of the inner surface of the joint that intersects the inner end surface and the inner edge of the inner surface of the rail that intersects the opposing inner end surface of the guide groove of the rail are configured to slide in a point contact state. It is preferred.

In the conveying path of the milking apparatus, the bottom surface of the slider moving in the track, the inner edge of the inner surface of the joint, and the inner edge of the inner surface of the rail are slid in a point contact state with low frictional resistance. Can be moved. Then, the slider can be smoothly moved inside the joint and the rail without being caught.

Then, the inner end portion 102b of the surface portion of the resin layer 100 exposed inside the guide groove 12 at the end portion of the rail 10 following the surface portion 102a of the resin layer inclined downward is separated from the inner side surface 10a of the rail end portion. It is located above. At the same time, the outer end 102c of the surface portion of the resin layer 100 exposed to the inside of the guide groove 12 at the end of the rail 10 following the surface portion 102a of the resin layer inclined downward is moved to the inner side surface 10a of the rail end. It is located below.

Then, the intermediate portion of the surface portion 102a of the resin layer inclined downwardly and the inner surface 10a of the rail end portion.
And the middle part of the vehicle crosses in a gentle V-shape when viewed from the side. The middle part of the surface portion 102a of the resin layer inclined downward and the inner surface 10a of the end of the rail.
And the middle part is smoothly connected without any steps. Then, the surface portion 102a of the resin layer inclined downwardly

It can be slid smoothly. Then, the slider 40 can be moved smoothly without being caught in the inner portion between the joint 20 and the end of the rail 10.

The surface portion 102a of the resin layer inclined downward is the surface portion 102 inside the resin layer 100 exposed to the inside of the guide groove 12 at the end of the rail 10, or the surface of the resin layer 100 in the middle. It may be provided in the portion 102.
In some cases, the surface portion 102a of the resin layer inclined downward may be provided over substantially the entire length of the surface portion 102 of the resin layer exposed inside the guide groove 12 at the end of the rail 10. And even in this case, similarly to the above, the middle part of the surface portion 102a of the resin layer inclined downward and the middle part of the inner side surface 10a of the end of the rail 10 are viewed from the lateral direction. They can cross in a gentle V-shape. Then, the middle part of the surface portion 102 of the resin layer exposed inside the guide groove 12 at the end of the rail 10 and the middle part of the inner side surface 10a of the rail end can be smoothly connected without any step. Then, the end of the rail 10 and the joint 20 are passed through the surface portion 102a of the resin layer inclined downward.
The slider 40 can be moved smoothly without being caught in the inner part between the two.

The inner end 102b of the surface portion of the resin layer 100 covering the inner surface of the joint 20 exposed inside the guide groove 12 at the end of the rail 10, and the joint 2 following the inner end 102b
The surface portion of the resin layer 100 that covers the inner surface of the inner side of 0
They are formed at almost the same height without any steps. The bottom surface of the slider 40 can be smoothly slid between the surface portions of the resin layer 100 without being caught.

Other configurations are the same as those of the above-described milking device transport path shown in FIGS. 8 and 9. In this milking device transport path, the end of the rail 10 inserted into the joint 20 is connected to the end of the rail 10. In the track 30 between the joint 20 and the slider 40,
It can be moved smoothly without being caught.

Further, as the slider 40 moving inside the joint 20 is greatly inclined or the like, the body 62 of the hook 60 hung from the slider 40 is inserted into the joint 2 through which it is inserted.
When the guide groove 22 is strongly pressed against the opposing inner end surface, the body 62 of the hook 60 is caught on the inner end surface by the surface covering the inner end surface is smooth and has less frictional resistance. This can be prevented by the resin layer 100. And the hook 6
0 can be smoothly moved inside the guide groove 22 of the joint.

The slider 4 moving in the orbit 30
The bottom surface of the joint 0 can be prevented from being hooked on the inner side surface of the joint 20 by the resin layer 100 having a smooth surface with little frictional resistance covering the inner side surface of the joint 20. And the slider 40
Can be smoothly moved inside the joint 20.

In addition, in the transportation path of the milking device shown in FIG.
As shown in FIG. 7 and FIG. 7, the bottom surface of the slider 40 is formed in a curved shape in the same shape as a part of the spherical surface. Then, the bottom surface of the slider 40 moving in the track 30 intersects with the inner edge 110 of the inner surface of the joint 20 that intersects with the opposing inner end surface of the guide groove 22 of the joint, and the opposing inner end surface of the guide groove 12 of the rail. Inner edge 210 of the inner surface of rail 10
Are configured to slide in a point contact state.

Then, the slider 40 moving in the track 30 is connected to the joint 20 or the rail 10 forming the track 30.
Minimizes frictional resistance from The slider 40 can be moved smoothly without being caught in the track 30.

The bottom surface of the slider 40 may be formed in the same shape as a partial side surface of the cone as shown in FIG. In this case, in the sectional view of the slider 40,
The bottom surface of the slider 40 is obliquely straight. And
Also in this case, the bottom surface of the slider 40 moving in the track 30 is fixed to the inner edge 110 of the inner surface of the joint 20 that intersects the opposing inner end surface of the guide groove 22 of the joint, and the opposing inner surface of the guide groove 12 of the rail. Rail 10 crossing the end face
Can be slid in a point contact state. And the frictional resistance which the slider 40 receives from the joint 20 and the rail 10 can be suppressed as small as possible.

The bottom surface of the slider 40 may be formed flat or the like as shown in FIG. Then, even when the bottom surface of the slider 40 is formed flat or the like, the coupling
The inner surface of the resin layer 10 with a smooth surface having a small coefficient of friction.
Since the joint 20 is covered with the resin layer 100, the inner surface of the joint 20 covered with the resin layer 100 can slide smoothly on the flat bottom surface of the slider 40 with little frictional resistance without being caught.

In addition, in the conveying path of the milking apparatus, the inner surface of the rail 10 on which the slider 40 slides also
As shown in FIG. 7, the surface having a small coefficient of friction is preferably covered with a resin layer 200 made of a smooth nylon resin or the like. In this case, the slider 40 can be slid smoothly on the inner side surface of the rail 10 whose surface is covered with the smooth resin layer 200 with less frictional resistance. Then, the slider 40 can be smoothly moved inside the rail 10 without being caught.

In the rail 10 shown in FIG. 7, the opposing inner end face of the guide groove 12 of the rail 10 is also covered with a resin layer 200 having a smooth surface. However,
The rail 10 and the guide groove 12 of the rail have a linear shape or a shape close to a straight line, and the slider 40 moving inside the rail 10 does not greatly tilt. Then, the trunk 6 of the hook 60 hung from the slider 40
2 is not strongly pressed against the opposite inner end face of the guide groove 12 of the rail. Therefore, the opposing inner end face of the guide groove 12 of the rail need not necessarily be covered with the resin layer 200 having a smooth surface.

In the rail 10 shown in FIG. 7, the opposite inner end face of the guide groove 12 of the rail is covered with the resin layer 200 because the resin layer 200 covering the inner side face of the rail 10 is used.
This is because it is necessary to form a locking groove 204 for locking the rail with the side edge of the guide groove 12 of the rail inside the resin layer 200.

On the outer edge of the resin layer 200, a resin side wall 206 having a smooth surface is provided so as to rise inside the rail 10. Then, the cylindrical side surface of the slider 40 can be guided along the inside of the resin side wall 206 whose surface is smooth. At the same time, slider 4
When 0 passes inside the rail 10, the slider 40
However, the resin layer 200 is connected to the rail 1 via the resin side wall 206.
