Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a method for vertically inverting a box-shaped pot-shaped seedling raising device by aligning and integrating a plurality of raising W bots on the same plane. Concerning the seedling pot used.

(Conventional technique i) A pot-shaped seedling nursery made of paper or resin is placed on a plate receiver, and while being transported by a conveyor, a small amount of covering soil is supplied into each pot with a soil covering supply device, and then sowing is carried out. There is a seeding plant that sows seeds using a device, then feeds the seedlings onto the floor using a floor feeding device, then turns the seedling raising device set upside down, and then removes the receiver that is now located on the upper side to irrigate. .

As a reversing device conventionally used in this type of plant, it holds the tip of the seedling nursery set that is sent in and
There is a type that can be swung around, but this type has a large amount of movement at the free end of the seedling nursery set, and it only holds one end of the seedling nursery set. There was a problem that a gap formed between the pot and the pot, causing the soil in the pot to spill out.

To solve this problem, we clamped the entire seedling nursery set,
A system has been developed in which the seedling raising device set rotates half a turn around the rotating shaft located in the center of the feeding direction, but in this case, the seedling raising device set after reversing is located at the same position in the feeding direction, so the previous seedling raising device While the set is being turned over, the feeding of the subsequent seedling grower set must be stopped, resulting in a problem of poor work efficiency.

(Means for Solving the Problems) In order to solve the problems of the conventional device described above, the present invention employs the following configuration.

That is, in the present invention, a box-shaped pot-shaped seedling-raising device in which a plurality of seedling-raising pots are aligned and integrated on the same plane is placed on a plate receiver, and a seedling-raising device set, which is made by covering a seedling box from above, is placed in a fixed position. A reversing device for vertically reversing the seedling raising device set while feeding the seedling raising device in the same direction, the device includes a clamping means for gripping the entire seedling raising device set, and is provided eccentrically to the front side in the feeding direction with respect to the central portion of the seedling raising device set in the front-rear direction. The gist of the present invention is to provide a reversing device for a pot-type seedling raising device, which is equipped with a rotating means for rotating the seedling raising device set together with the clamping means and inverting the seedling raising device set vertically about a rotation axis perpendicular to the feeding direction. .

(Function) Since the seedling nursery set is rotated while being held in its entirety, no soil leakage occurs. Moreover, since the rotation axis is located on the forward side in the feeding direction rather than the central part of the seedling raising device set in the front-rear direction, the seedling raising device set after reversal will move forward in the feeding direction by the eccentricity thereof.

(Example) Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Nipping roller 35. . . constitutes a clamping means that clamps and holds the seedling raising device set 20 vertically. In this embodiment, the front end and the middle part of the seedling raising device set 20 are clamped, but depending on the case, only the middle part may be clamped, and the seedling box 18 and the receiver PIi 10 are clamped. The flange portion may be clamped instead of the plate surface. In other words, any clamping method may be used as long as the clamping force is spread throughout the seedling raising device set 20.

Further, in this embodiment, the pinching roller 35 is made of an elastic body,
Although the seedling raising device set 20 is held between the rollers 35 by using its own elasticity, the rollers 35 are made of other materials,
The roller shaft 33 may be pressed by a spring or the like.

A feeding device 37 and a drawing device 38 are provided before and after the rotating frame 31.
is provided. The feeding device 37 has four roller shafts 40. on a pair of left and right frames 39. -... are provided, and three rollers 4 each made of an elastic body are provided on each of these roller shafts 40.

can be conveyed to. The clutch 47 is turned on and off by a solenoid that is turned on and off by a limit switch 50, and when the tip of the seedling raising device set 20 sent by the feeding device 37 reaches the position of this limit switch 50. When it is detected that the
-r is turned on, and the rotating shaft 30 is united with the rotating frame 31 and stops rotating by 180 degrees. Since this clutch 47 is a one-way clutch, it is brought up by the clutch when the rotation stops.
tI triple set 20 is prevented from recoil upwards.

In the figure, 49 and 49 are guides along which the end of the seedling raising device set 20 rotates in an arc. In addition, limit switch 5
0 is provided with a return spring 51, etc., and its detection part 50a is swingable in the front-rear direction and up-down direction, and moves downward when struck by the lower surface of the 180-degree rotating seedling raising device set 20. However, when the seedling raising device set 20 finishes passing, it moves up again and returns to its original position.

The drawer device 38 has a pair of frames 3 similar to the feeding device 37.

The rotational force of the motor 43 is transmitted through the motor 3. In addition, each roller 5. of the conveyor stand A3. -... are similarly rotated by power transmitted via the sprocket 54 and chain 55.

In this reversing device H, the rotating shaft 30 is located on the front side of the front-rear center position in the feeding direction of the seedling raising device set 20 when reversing. That is, the feeding device 37
When the seedling raising device set 20 pushed between the upper and lower pressure rollers 33, 33 of the rotating frame 31 has just come off the rollers 41, 41 of the feeding device 37, its tip comes into contact with the limit switch 50. However, at this time, the distance a from the rear end of the seedling raising device set 20 to the rotating shaft 30 is larger than the distance #1b from the rotating shaft 30 to the front end ( a>b). In this state, it is rotated 180 degrees in the direction of the arrow X around the rotating shaft 30, so when the rotation is finished and it is in the horizontal state again, the rear end of the seedling raising device set 20 (front end before inversion) is (a-b)
It will be in a state where it has progressed in the feeding direction.

Therefore, even during the reversal operation of the advance seedling nursery set (
It is possible to send the subsequent growing convex set 20 only by the distance a-b), and it becomes possible to carry out the work continuously without stopping the conveyance by the conveyor. Note that the pinching roller 35 of the rotating frame 31. -... are not forcibly rotated, so the seedling raising device set 20 will stop at that position after being reversed. The paper is pressed by the rollers 40 and 40 on the front side of the drawing device 38, and is forcibly transferred again.

Next, on the rear side of this reversing device H, there is provided a removing device (2) for removing the receptacle 1O that has been inverted and placed on the upper side. The removing device (2) includes a lifting tool 61 supported vertically and rotatably by a support 60, and a pin 62 pivotally attached to the rear end of the lifting tool 61, and the rear end is connected to a receiving material 63.
a link 65 supported by the link 65;
A pin 66 protruding from the lever 67 is loosely fitted into an elongated hole 68 of the lever 67. The base of the lever 67 is pivotally connected to a shaft 70 .
An arm 71 provided at the end of the eccentric cam 73 connects the bin 74
It is pivoted on. The eccentric cam 73 is a one-turn clutch 75
The clutch 75 is attached to the roller shaft 76 via a roller shaft 76, and when the clutch 75 is operated by one person, it is forcibly rotated by one rotation by the rotational force of the motor 43. Note that the clutch 75 is turned ON-OFF by a limit switch 78 that detects that the seedling raising device set 20 has arrived.
It is manually operated by a solenoid 80.

Seedling raising device set 2 that has been turned upside down by the reversing device H
When the tip of the 0 reaches the tip 61a of the pulling tool 61 which is held in an inclined state so that the front side is positioned downward, the tip 61a is attached to the container 10 of the seedling raising device set zO. It enters the lower side of the collar 10b, and the receiver 10 is pushed upward along the inclined upper surface of the lifting tool 61. During this time, the seedling grower 9 moves horizontally on the rollers of the conveyor table A4 together with the seedling box 18 in which it is placed. The receiver that has climbed onto the lifting tool 61 eventually reaches the link 65, where it is held horizontally by gravity.

When it is detected that the combination of the seedling grower 9 and the seedling box 8 has reached the position of the limit switch 78, the solenoid 80 is actuated to turn the one-turn clutch 75 to "one person".

As a result, the eccentric cam 73 rotates once, and during this rotation, the lever 67 moves, causing the lifting tool 6 to move as shown by the chain line in the figure.
1 and the link 65 are in a straight line and tilted greatly, and the receiver held on the roller 85 of the conveyor table A4
, 8B and onto the lower rail 90. The receiver 1θ supplied on the rail 90 is carried by the rail to a take-out position.

The seedling raising device 9 and the seedling box 18 are sent to the subsequent soil filling device J by a conveyor. The soil filling device J is equipped with a soil storage tank 92 and a soil feeding device 93, and supplies soil to the spaced portions of each pot of the inverted seedling raising device 9 after about 8 minutes.

Note that at the time when the tip of the preceding seedling raising device set 20 presses the limit switch 78, the succeeding seedling raising device set 20
The transfer speed is controlled so that the tip of the rollers 85 and 86 does not overlap the gap S between the rollers 85 and 86.

An irrigation device K is provided on the rear side of the soil filling device. The watering device is a device for watering the surface of the seedling growing device 9, and has a pump 94 attached to a fountain nozzle 95. The seedling growing device irrigated by this watering device K is taken out from the conveyor table A5 together with the seedling box 18 and stored in a predetermined seedling growing room.

(Effects of the Invention) As is clear from the above explanation, the reversing device of this pot-type seedling nursery is centered around a rotating shaft perpendicular to the feeding direction, which is eccentrically provided toward the front of the center in the front-rear direction in the feeding direction. By rotating the seedling raising device set, the seedling raising device set is turned upside down, so that when the reversing operation is completed, the seedling raising device set has advanced by the eccentricity. Therefore, there is no need to interrupt the feeding of the subsequent seedling raising device set even during the reversal operation of the preceding seedling raising set, resulting in high work efficiency.

The seedling nursery set can be turned over while being held in its entirety, not just one end, effectively preventing soil from leaking due to gaps between the seedling nursery, receiving plate, seedling box, etc. .

Note that it is clear that this reversing device can be used for reversing things other than seedling growers.
