Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic feeder for feeding a seedling box to a desired processing device.

[0002]

2. Description of the Related Art Conventionally, in a case where a seedling box is supplied to a processing device such as a washing machine for washing treatment, the seedling boxes to be washed are manually fed to the processing device one by one. . Therefore, in the case of processing a large number of seedling boxes, it takes a lot of labor and the worker replacement staff must be on standby.

[0003]

SUMMARY OF THE INVENTION In view of the present situation as described above, the present invention unmanned by automatically supplying a seedling box to a processing device by hand, thereby saving labor for seedling box supply work. The present invention was created for the purpose of providing an automatic supply device that supplies each seedling box one by one in a timely manner and reliably supplies it to the processing device.

[0004]

In order to achieve the object described in the preceding paragraph, the present invention provides a feeding belt for placing and feeding a seedling box, and a seedling box which is stacked on the feeding belt.
A processing device that includes a chuck mechanism that holds a second item and a lifting mechanism that raises and lowers the chuck mechanism, and that attaches the protrusions of the feeding belt of the supply belt at regular intervals to lock the seedling box to the protrusions. The chain with a protrusion to be conveyed to is suspended, and a protrusion detection sensor is provided at a predetermined position beside the chain with a protrusion. Based on the ON operation of the protrusion detection sensor, the chuck mechanism is opened and closed and the lifting mechanism is moved up and down. By linking the seedlings, the seedling boxes on the supply belt are sent out one by one and inherited by the chain with projections. Further, the supply belt is connected to the alligator stock conveyor, and a seedling box detection sensor for detecting the presence or absence of the seedling box on the supply belt is provided, and the stock motor is driven by the OFF detection of the sensor. Then, the seedling box on the stock conveyor may be transferred onto the supply belt.

[0005]

With this structure, when the seedling boxes stacked on the supply belt are present, when the chain with projections rotates and the projections attached at regular intervals come into contact with the projection detection sensor provided at predetermined positions, The protrusion detection sensor detects this and closes the chuck mechanism to clamp the second seedling box from the bottom on the supply belt, and the chuck mechanism in the clamped state is lifted by the lifting mechanism. The seedling boxes that have been raised and lifted up from the second one are lifted up, so the seedling boxes left on the supply belt are sent out by the supply belt, locked by the projections, and conveyed to the processing device by the chain with the projections. And
The lifting mechanism descends after a certain period of time, the chuck mechanism opens to release the sandwiched state, and the second seedling box from the bottom comes to be placed on the supply belt. When the projection contacts the projection detection sensor, the chuck mechanism and the lifting mechanism repeat the above-mentioned operation, and the seedling box is sent out by the supply belt and inherited by the chain with the projection and conveyed one by one to the processing device. is there.

Further, when the seedling box disappears or does not exist on the supply belt, the seedling box detection sensor is turned off and the stocking motor is turned on, so that the stock conveyor is rotated. The seedling boxes placed on the stock conveyor are then transferred onto the supply belt and delivered one by one as described above.

Is a freely rotatable roller that supports the movement of the transfer belts (39) and (39).

The operation unit (43) is provided in the stacking device (C) as shown in FIG.
(M1), stock motor (M2), protrusion detection sensor (S1), seedling box detection sensor (S2), chuck solenoid valve (V1), lifting solenoid valve (V2) A program is organized to operate as shown in the operation system diagram in "7".

That is, the operation system diagram "FIG. 7" and the operation explanatory diagram "FIG. 1" will be explained. When the main switch (44) of the driving operation unit (43) is turned on, the operation starts from the later stage and the projection is provided. When the motor (not shown) for driving the chain (4) is turned on and the supply motor (M1) is turned on, the chain (4) with protrusions and the supply belt (1) are respectively indicated by arrows (a) (b). ) Rotate in the direction of. At this time, if the seedling box (a) is placed on the supply belts (1) and (1) as indicated by phantom lines, the seedling box (a) is rotated by the rotation of the supply belts (1) and (1). Although it is about to be delivered to the rear side, the second one from the bottom is blocked by the connecting member (25) and the bottom one is the weight of the two or more piled up from the bottom and the one directly above (2 from the bottom). By the locking action with the first one, the stopped state is maintained while making sliding contact with the conveying surface of the supply belts (1) (1).

The presence of the seedling box (a) in this stopped state is detected by the seedling box detection sensor (S2), which is turned on, and after 0.5 seconds, the projection (4a) of the projection-attached chain (4) is rotated. When the protrusion detection sensor (S1) is turned on by contact, 1
After 2 seconds, the chuck solenoid valves (V1) (V1) are turned on and the sandwiching plates (23) (23) move in the directions of the arrows (c) to close the chuck. 0.5 seconds later, the lift solenoid valve (V2) is turned on. O
Operate N and lift the second or more seedling box (a) from the bottom as shown by the arrow (d). By this lifting, the bottom seedling box (a) left on the supply belts (1) (1) is sent out to the rear, and at this time, the projections (4a) of the chain with projections (4) are timely. Locked to (a) (e)
Then, it is pushed to the processing device (A).

The lifting solenoid valve (V2) is turned off after 1.5 seconds from the ON operation to lower the lifted seedling box (a), and 0.3 seconds after that, the chuck solenoid valves (V1) (V1).
Is turned off and the chuck is opened, and the second one from the bottom is placed on the supply belt (1) (1) and the projection (4a) that follows is stopped and stopped as described above. Contacting the protrusion detection sensor (S1) causes the chuck mechanism (2) and the lifting mechanism (3) to repeatedly carry their operations to the chain with protrusions (4) and convey them to the processing device (A). .

Next, when the seedling box (a) is not present on the supply belts (1) and (1) and the seedling box detection sensor (S2) is OFF, this OFF causes the stock motor (M2). Is turned on, the transfer belts (39) (39) are driven, and the seedling boxes (a) placed on the belts (39) (39) are transferred onto the supply belts (1) (1). , When the seedling box detection sensor (S2) is turned on by this transfer, the stock motor (M2) is turned off and the transfer belt (39)
(39) stops.

In this way, the supply belt (1) (1)
The seedling boxes (a) stacked or placed on the transfer belts (39) (39) are delivered one by one by the supply belts (1) (1) and processed by the chain (4) having a projection (A).
In this embodiment, the processing device (A) is a cleaning device, and the cleaning water is stored in the water tank (45) as shown in FIG. A sucking tube (46) is attached and sprayed on the seedling box (a). In this case, when the water in the water tank (45) falls from the limit water level, the water level detection sensor (S3) detects this and turns on the solenoid valve (V3) to replenish the water and stop the operation of the cleaning device. The device is safe.
