The present invention relates to a transshipment device used when transferring boxes to greening carts, etc.

[Conventional technology 1] M-boxes for raising seedlings are stacked without gaps during germination to keep the interior dark, but after germination, gaps are left between the seedling boxes to allow for sunlight and space for leaf elongation. Can be transshipped. Conventionally, this work of transshipping W boxes was done manually.

[Problems to be Solved by the Invention] However, the conventional manual method has the problem of poor work efficiency and high labor costs.

[Means for Solving the Problems] In order to solve the second problem, the present invention has the following configuration.

The receivers 8b, . . . are provided facing each other at intervals wider than the above.

Next, FIG. 8 is a block diagram showing the control mechanism of this transshipment device 1. In the seedling box retrieval 9aL3, there is a seedling box a.
A stop switch 80 detects that the protrusion 25 of the mounting base comes into contact and turns off the valve of the air cylinder 22.
,81. An upper limit switch 83 that detects that the seedling box mounting base has risen to the upper limit position, a lower limit switch 84 that also detects that the seedling box mounting base has descended to the lower limit position, and a seedling box Ji
A lift switch 85 is provided for detecting that the mounting table has been raised by a certain amount when it has moved horizontally to the L side of the germination cart 7. The loading device 4 also includes a support arm 6.
2.62 is raised to the upper limit position by the upper limit switch 87. Similarly, a lower limit stiffener 88 detects that the support arm has lowered to the lower limit position, a lift down switch 89 detects that the support arm has further lowered by a slight amount from the lower limit position, and detection switches 57 (A), 57 of the stopper device. (B) is provided. and,
Detection signals from each of these switches are supplied to the CPU 90,
Output commands are issued to each air cylinder, motor, renoid, etc. The operation will be explained below based on the flowchart shown in FIG.

The germination trolley 7, on which a predetermined number of seedling boxes 99 are stacked in two rows each in the front, back, left, and right directions, is stopped at the predetermined position shown in the figure, and the support arm 62 of the loading device 4
．． After attaching the empty greening trolley 8 to 62, operation of the M changing device 1 is started.

First, the seedling box mounting table 20 at the lower limit position
2 is inserted into the gap between the germination cart 7 and the lowest seedling box. Initially, the stop switch 80 is activated, so the air cylinder 22 is stopped in a half-retracted state. Next, the motor 59 is started, and the seedling box 'a mounting table 0 is raised by a slight amount until it is detected by the lift switch 85. This allows the seedling boxes 99 to be stacked in stacking position II on the front left side of the cart. -... is placed a on the fork portion 20a of the seedling box mounting stand. Then, the air cylinder 22 is expanded and the seedling box mounting table 20 returns to its original position.

Subsequently, the camshaft 31.31 of the separation device 2A rotates once in a predetermined direction, and the air cylinder 33 of the extrusion device 212B contracts. J(b).

As shown in (C), the spiral cam 31b is inserted between the uppermost seedling box and the second seedling box while the cam shaft 31.31 rotates once and separates them. At this time, the air cylinder 33 contracts. As the engaging plate 34 presses the rear end surface of the seedling box at the farthest stage, the seedling box is pushed onto the conveying device 2. When these series of operations are completed, the motor 14 is activated to raise the seedling box mounting table 20 by the height H of the seedling box. and,
The drawing device and extrusion device are activated again. In this way, the seedling boxes stacked in the 8 1'' i-boxes 20 are successively pushed out to the transport device 2.

The seedling box pushed out by the transport device 2 is transferred to the transmission roller 41.
It is sent forward (in the X direction) by the rotation of . On the way, every other passing IW box is pulled to the left side of the conveyor by the action of the transfer air cylinder 44, which repeats the contraction operation at twice the cycle of the air cylinder 33. Therefore, the F stomach boxes are sent to the loading device 4 alternately through the right and left sides of the conveyor.

The m boxes sent by the transport device 2 are delivered to the roller conveyor 51 of the loading device 4, and further transported forward. At this time, the solenoid 58 is energized and the stopper device ff55 (B) is raised, so the 17 boxes are transferred to the front upper stop position A, passing under the stopper device 55 (B). The stopper device 55 (A) comes into contact with the receiving member 56 and stops. At the same time, this is detected by the detection switch 57 (A), and the loading air cylinder 70
(A) contracts. The suppression plate 69 of the air cylinder 70 (A) holds two seedling boxes juxtaposed on the conveyor 1-,
Push it into the bottom of the front storage section S (A) of the greening table ilI 8. Subsequently, the motor 64 is operated to lower the greening trolley 8 by a distance Hh for attaching the receiver 18b. Thereafter, the pushing of seedling boxes and the lowering of the stand Ilj are repeated in the same manner, and m boxes are sequentially loaded into the storage section S (A) on the front side of the greening cart 8 from the bottom. When all the seedling boxes are stored in the storage section S (A), the greening table 1tE8 is raised to the original one-hi limit position, and the solenoid 57 of the stopper device J55 (B) is de-energized.

+'+7 Tla When the mounting table 20 rises to the upper limit position and all 117 boxes are pushed out, the fNm mounting table 20 descends to the lower limit position. Then, the air cylinder 22 contracts again, but this time the stop switch 7 81 is activated, so the seedling box a placement stand 22 is moved from the germination trolley 7.
It is held out to the stacking position ■ on the front right side of the . Thereafter, the take-out device 3 performs the same operation as the previous time, and sequentially transports the seedling boxes at the stacking position (3) to the loading device 4.

On the other hand, in the loading device 4, the solenoid 72 is de-energized as described above, so the loading device 55 (B) is lowered, and the seedling boxes being transported are stopped at the transport stop position B. . And this time, loading air cylinder 7
0 (B) is activated and the seedling boxes are sequentially loaded into the storage section S (B) on the rear side of the greening cart 8.

When the implantation is completed, the convex portion 61 of the support arm is retracted and the moving air cylinder 50 is extended, thereby moving the loading device 4 along with the machine frame 47 in the Y direction. after that,
The fully loaded greening trolley 7 is replaced with an empty greening trolley. After the replacement is completed, the loading device 4 is returned to its original position.

Next, the germination trolley 7 is moved forward to a stacking position of 4 m on the rear side.
, m boxes from the RV are transferred to the greening trolley 8. That is,
The seedling boxes for one germination trolley are loaded onto two greening trolleys. Therefore, the greening trolley 8 can accommodate the m boxes 99 with sufficient vertical clearance, providing favorable conditions for greening.

In this way, this m-box transshipment device l is equipped with various detection switches and controls the operations of the air cylinder, motor, etc. with the CPU, thereby automatically transshipping the seedling boxes without any human intervention. be able to.

[Effects of the Invention] As is clear from the above description, the seedling box refining device according to the present invention can automatically and accurately change the seedling boxes piled up on a platform such as a germination trolley. It is now possible to transfer it onto a platform such as a greening trolley.
