Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a seedling raising box feeding device for stacking seedling raising boxes in a frame and transporting the seedling raising boxes one by one for the next work.

[0002]

[Prior art]

 Conventionally, the structure of a nursery box feeding device for feeding the nursery boxes one by one to a soil-filling machine, a seeding machine, a washing device, etc. has been publicly known. For example, it is a technique disclosed in Japanese Utility Model Laid-Open No. Sho 63-158151. According to the conventional technique, the nursery boxes are stacked and stacked in the storage frame, and the upper and lower claw-shaped locking bodies provided at the lower portions of the front and rear storage frames allow the lowermost portion and the edge of the nursery box above it. By alternately locking the seedlings, the nursery boxes were dropped onto the chain conveyor one by one and transported to the next process.

[0003]

[Issues to be solved by the device]

 However, if the nursery box is configured to drop by alternately locking with the two locking bodies, the position of the nursery box will be misaligned when dropped, and it will not be conveyed in parallel with the conveyor, and it may be caught in the next process. It was impossible to sow accurately. In the next step, when troubles such as clogging occur, the seedling raising box was transported by the chain conveyor, so the rear end of the seedling raising box is forcibly transported by the locking body that protrudes onto the chain. There was a problem such as breaking the nursery box.

[0004]

[Means for solving the problem]

 The problem to be solved by the present invention is as described above. Next, the means for solving the problem will be described. That is, in the seedling raising box feeder that takes out the seedling raising boxes 4 one by one from the lower part of the collecting frame 3 and carries them out by the conveyor belt 2, the sensor S1 is provided below the collecting frame 3 to detect the presence or absence of the lowermost raising box. A sensor S2 is provided on the discharge side of the carrier 1 to detect the retention of the nursery box, and a nursery box take-out device A is arranged in front of and behind the stacking frame 3 so that the next nursery box can be taken out when the sensor S2 is ON. It is composed.

[0005]

[Action]

 With this configuration, the presence or absence of the nursery box 4 is detected by the sensor S1, and when the nursery box 4 is present in the stacking frame 3, the cylinder 6 is driven to engage the locking claws of the nursery box unloading device A. 14 The seedling raising box 4 placed on the conveyor belt 2 is lowered and conveyed to the discharge side, and the second raising seedling box from the bottom is locked and lifted when the locking claws 14 are raised to raise the seedling raising box. When the sensor 4 is transported and the sensor S2 is turned on, the cylinder 6 is driven again, the next seedling raising box is placed on the conveyor belt 2, and the above operation is repeated.

【Example】

 Next, an embodiment of the present invention will be described. FIG. 1 is a front view of the seedling raising box supply device of the present invention, FIG. 2 is a control block diagram, FIG. 3 is a side view of a seedling raising box take-out portion, and FIG. 4 is a side view of the state where the seedling raising box is also placed on a conveyor.

To explain the overall configuration in FIG. 1, a conveyor belt 2 is wound around a conveyor 1 and a stacking frame 3 is erected on the starting end side of the carrier 1, and the stacking frame 3 is a nursery box 4. The seedling-growing boxes 4 are stacked and accommodated as a size for storing the seedlings, and an opening 3a through which the seedling-growing boxes 4 can pass is opened in the lower part of the stacking frame 3 on the next process side. Then, the sensor S1 is arranged at a position on the lower side surface of the stacking frame 3 which receives the lowermost seedling growing box 4 to detect whether or not the seedling growing box 4 is present in the stacking frame 3, and both sides of the lower side of the stacking frame 3 are detected. A nursery box extractor A is installed in the section.

Further, a motor M1 is arranged on the terminal end side of the carrier table 1 and the carrier belt 2 can be rotated by driving the motor M1 so that the nursery box 4 ejected from the stacking frame 3 is detected. A sensor S2 is provided on the discharge side of the table 1, and the sensor S2 can be fixed to the elongated hole opened in the traveling direction with a bolt or the like so that the sensor S2 can be adjusted in position right and left. The sensors S1 and S2 are composed of reflection type optical sensors and switches, and are connected to a controller 5 as shown in FIG. 2. Further, the controller 5 includes an electric cylinder that is an actuator of the motor M1 and the take-out device. It is connected to the 6 motor M2. However, instead of the electric cylinder, a hydraulic cylinder, a pneumatic cylinder or the like may be used to switch the electromagnetic valve so as to expand and contract the cylinder.

As shown in FIGS. 1 and 3, the nursery box take-out device A has a structure in which the center of the connecting plate 10 is fixed to the tip of the piston rod 6a of the cylinder 6 fixed to the carrier 1. The drive rods 11 and 11 are erected on both sides of the connecting plate 10, and the drive rods 11 and 11 are slidably supported by being fitted and inserted in the guide pipes 12 in the middle of the drive rods 11. The locking claw 14 is pivotally supported. 17 is a bush. The locking claw 14 can be rotated upward from the horizontal direction, but is restricted downward by a notch 11a of the drive rod 11, and a spring 16 is engaged with a pin 19 in the middle of the locking claw 14. The other end of the spring 16 is locked by a pin 15 which is horizontally mounted on the upper end of the drive rod 11 above the pin 13, and urges the locking claw 14 to rotate upward.

An upper end of a rod 20 is pivotally supported by a pin 19 projecting from the locking claw 14, and a lower part of the regulating rod 20 is inserted into a ring 21 projecting from the guide pipe 12 and is attached to a lower end thereof. The spring 22 is externally fitted and locked with nuts 23. The spring force of the spring 22 is made stronger than the spring force of the spring 16, and the spring force of the spring 16 is set so as not to lift the seedling raising box 4. The drive rods 11 and 11 are provided at the front and rear respectively so that the edge portion 4a of the seedling raising box 4 can be placed on the locking claws 14, 14 ...

With this configuration, the seedling raising boxes 4, 4, ... Are placed in the stacking frame 3 and placed on the locking claws 14, 14, ..., and the motor M1 is driven. When the conveyor belt 2 is rotated and the motor M2 is driven to reduce the cylinder 6, the drive rod 11 is guided by the guide pipe 12 and descends as shown in FIG. 4, and the seedling raising box 4 is placed on the conveyor belt 2. When the drive rod 11 is further lowered, the biasing force of the spring 22 on the regulating rod 20 is released, the tip of the locking claw 14 is disengaged from the edge 4a of the seedling raising box 4, and The locking force causes the locking claw 14 to rotate upward.

When the locking claw 14 is disengaged from the edge 4 a, the motor M 2 is reversed and the cylinder 6 is extended, and when the upper end of the spring 22 comes into contact with the ring 21, the spring force of the spring 16 is overcome to overcome the locking claw 14. The regulation rod 20 pulls to rotate the locking claw 14 downward, locks the edge 4a of the second seedling raising box 4 from the bottom as shown by the chain double-dashed line in FIG. Lift up 4. When the nursery box 4 is placed on the conveyor belt 2, the nursery box 4 is transported, but the second and subsequent nursery boxes 4 from the bottom are stopped by the collecting frame 3 and are not transported. Before the second nursery box 4 from the bottom is dropped onto the conveyor belt 2 in the rear space, the drive rod 11 is raised to lift the second and subsequent nursery boxes 4 from the bottom.

Then, when the drive rod 11 rises to the rising end, the sensor S1 detects the presence or absence of the nursery box 4, and if there is, waits until there is a signal from the sensor S2, and the signal from the sensor S2 is input. Then, the motor M2 is again rotated normally and lowered. In other words, until the sensor S2 is turned on, there is the nursery box 4 on the conveyor belt 2 in the stacking frame 3, or the nursery box 4 is not conveyed due to being caught by something, so continue. Even if the nursery box 4 is lowered, it will ride on the nursery box or carry it continuously to collide with the previous nursery box, which will only increase the trouble. Even if the sensor S2 is turned on, if the sensor S2 is turned on for more than the passing time, it means that the sensor M2 stays, so that the driving of the motor M2 is stopped. Further, by adjusting the position of the sensor S2 in the advancing direction, the feeding timing (conveyance interval) of the seedling raising box can be changed so that the seedling raising box 4 can be fed according to the work of the next step.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. That is, the next nursery box is not taken out until the nursery box carried out by the conveyor belt is detected, so that even if the nursery box is clogged on the carrier or in the next process, the nursery box is not continuously supplied. It is now possible to easily perform repairs without damaging the nursery box and promoting problems.
