[0002]

2. Description of the Related Art Conventionally, as an automatic feeding device capable of automatically supplying the feed weighed for each cow to each of the feeding tanks provided in a plurality of stalls, the automatic feeding device disclosed in Japanese Patent Laid-Open No. 60-55359 is disclosed. Feeding devices are known.

This automatic feeding device is a circulating type hopper that is hung from the ceiling or the like, a conveyor for driving the conveyor, a drive device for driving the conveyor, and a hopper for feeding feed that is movably mounted on the conveyor. A feed supply device for supplying feed to a hopper for feeding feed at a predetermined position,
Equipped with push rods corresponding to each feed tank, when feeding feed, push the push rod corresponding to the feed feed tank and circulate the feed hopper in the forward direction. By doing so, when the hopper passes through the pushing rod, the bottom lid of the hopper is opened by the pushing rod, and the feed falls from the hopper and is supplied to the feeding tank.

[0004]

However, such a conventional automatic feeding device has the following problems.

First, since the pushing rods individually controlled by the control device are provided for each feeding tank, a large number of pushing rods and wiring for connecting each pushing rod and the control device are required, which makes the equipment complicated and costly. Not only will this lead to uptime, but problems will be more likely to occur, leading to a lack of reliability.

Secondly, since the amount of movement of the hopper cannot be controlled accurately, the hopper is circulated in the forward direction so that the food is fed when it passes through the target feeding tank (push rod). Therefore, since the hopper has to constantly go around the endless conveyor, feeding time becomes long, efficient feeding cannot be performed, and wasteful energy consumption is caused.

Thirdly, when a worker, a cow, or the like hits the moving hopper, it is not possible to quickly and accurately carry out abnormal detection such as detection and automatic stop control.

The present invention has solved the problems existing in such conventional techniques, and can greatly simplify the equipment and reduce the cost, and further improve the reliability, the efficiency of feeding and the energy saving. At the same time, it is an object of the present invention to provide an automatic feeding device capable of performing detection in an abnormal state, automatic stop control, etc. quickly and accurately.

Further, the control unit 9 has an abnormality detection function of detecting an abnormality due to a change in relative rotation difference between the drive pulley 17m and the detection pulley 17n.

Next, the operation of the automatic feeding apparatus 1 according to this embodiment will be described with reference to the flow charts shown in FIGS.

First, various feeding conditions such as feeding time (about six times a day), feeding amount and blending conditions for individual cows are set in the computer unit 72 in advance. The amount of feed and the mixing conditions for each cow can be set based on the amount of milk, the period of milk, the weight, and the like.

On the other hand, the feeding operation proceeds as follows.
It is now assumed that the first carry 7x is waiting at the waiting position (step S1). When the set time is reached, the feed loading process is first performed (steps S2 and S3). The feed loading process is executed as shown in FIG. First, the control unit section 71 operates the driving section 5 to move the wire member 6 in the forward direction Df (step S31).

As a result, the carry 7x is set at the home position Ps just below the exit of the screw conveyor 65 (steps S32 and S33). At this time, the bottom lid 11 of the carry 7x is automatically closed by the automatic lid closing mechanism (not shown) and locked by the lock mechanism 12.

Further, in the feed mounting portion 8, the feed corresponding to the cow in the feeding tank 2a for feeding is measured.
In this case, the TMR feed is measured by the mixer 61,
In addition, the concentrated feed is measured by the first screw auger 62, the additive is measured by the second screw auger 63, and each measured feed is mounted on the carry 7x while being stirred by the screw conveyor 65 from the bottom tank 64. (Steps S34, S35, S36). Such mounting processing is similarly executed for all the remaining carries 7y ... (Step S37).

When the feeding of all the carriers 7x ... With the feeding unit 8 is completed, the carriers 7x ... With the feeding are moved in the forward direction Df (steps S4, S5). In this case, the carriers 7x ... Are moved to the target feeding tanks 2a ... And stopped at positions where they slightly pass the corresponding dogs 10a ... (Steps S6, S7).
At this time, although the upper ends of the clutch levers 16 ... In the clutch mechanism units 13 ... are rotatably displaced by hitting the dogs 10a, the lower ends of the clutch levers 16 ...
.. is displaced in a direction away from the lock lever 15 ..., the locking of the bottom lid 11 ... by the lock mechanism portion 12 is not released. Further, the movement position of the carriers 7x, that is, the movement amount of the wire member 6 is accurately detected by the movement amount detection unit 21 from the rotation of the detection pulley 17n, and the movement position of the carriers 7x is preset. Therefore, the carry 7x ... Is stopped at the point where the movement amount detected by the movement amount detection unit 21 matches the set movement amount.

On the other hand, if the wire moving mechanism 4 is controlled to move the carries 7x in the reverse direction Dr, the clutch levers 16 in the clutch mechanism 13 ... (Steps S8 and S9). At this time, the clutch levers 16 hit the dogs 10a in the opposite direction Dr, so that the lower ends of the clutch levers 16 push the upper ends of the lock levers 15 so that they are rotationally displaced. As a result, the lower ends of the lock levers 15 are also displaced, and the lock on the bottom lids 11 is released.
Therefore, the bottom lids 11 ... Open by their own weight and carry 7x ...
The feed housed in is dropped and supplied to the inside of the feeding tank 2a ... (Steps S10 and S11). In this case, dog 1
Since 0a ... is a fixed mere rod, the equipment can be simplified and the cost can be reduced. On the other hand, if the carry 7x ... Is moved in the reverse direction Dr as it is, the home position P
It is returned to the s side (step S12). Therefore, feeding efficiency and energy saving can be achieved. And the whole feeding tank 2a ...
The same feeding process may be performed on the (step S1
3).

By the way, the tensionable pulley (detection pulley) 17n provided so as to be displaceable is urged by the weight 20 suspended in the tension applying mechanism 19, and a certain tension is applied to the wire member 6. Therefore, since a predetermined slip can be generated between the drive pulley 17m and the wire member 6, even when a worker, a cow, or the like hits the moving carry 7x ... The slip between the members 6 softens the impact. At this time, the drive pulley 17
Since the relative rotation difference between m and the detection pulley 17n changes,
If the change in the relative rotation difference is detected by the abnormality detection function of the control unit 9, the abnormality processing such as the automatic stop control can be quickly performed. Even if slippage occurs, the movement amount of the wire member 6 is detected by the rotation of the detection pulley 17n, so the movement amount is accurately detected without being affected by the slippage.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, the transport rails may have shapes other than C-shaped channels and do not preclude the use of circulating rails. Further, the lock mechanism portion and the clutch mechanism portion can be replaced with another structure having the same function, and the clutch mechanism portion may be provided in the dog. Furthermore, the tensioning mechanism does not prevent the use of other biasing means such as springs.
Further, the tension pulley and the detection pulley may be separately and independently used. In addition, the detailed configuration, shape, technique, etc. can be arbitrarily changed without departing from the scope of the present invention.

[0039]

As described above, the automatic feeding device according to the present invention, in particular, has a dog provided corresponding to the feeding tank, a lock mechanism portion for locking the bottom lid of the carry that opens in the natural state at the closed position, Since it includes a clutch mechanism section that is pushed by the dog only when the carry passes in the reverse direction with respect to the dog to unlock the lock mechanism, and a control section that controls the movement of the wire member in the forward and reverse directions. , And has the following remarkable effects.

Since the dog need only be a fixed rod body, the equipment can be simplified and the cost can be reduced, and troubles such as breakdowns can be eliminated, and reliability can be improved.

By providing the control unit with the movement amount detection unit for detecting the movement amount of the wire member by rotating the detection pulley, the carry can be accurately controlled to move in the forward and reverse directions, thereby eliminating unnecessary movement. Therefore, feeding efficiency and energy saving can be achieved.

Even when an operator, a cow, or the like hits the moving carry, the abnormal processing such as the detection and the automatic stop control can be swiftly and appropriately performed.
