It is composed of a sensor S2 and the like.
Then, in the budding carriage transport unit 3, a manual carrying-in process in which an operator manually carries the budding carriage 2 to the starting end of the carrying conveyor 18, and automatically carries in the manually carried budding carriage 2 to the transfer position. Automatic carrying-out processing, automatic carrying-out processing for automatically carrying out the germination trolley 2 after the completion of the transshipment work to the terminal end of the conveyor 18, and an operator manually carrying out the automatically carried-out budding carriage 2 to a predetermined position. By repeating the manual unloading process at a predetermined timing, the germinating carts 2 are sequentially supplied to the transfer work position of the conveyor 18.

That is, when the worker pushes the germination trolley 2 backward from the front side of the germination trolley transport section 3 so as to be guided by the entry guide 19, the germination trolley 2 enters between the left and right roller guides 17. At the same time, the bottom front side of the budding cart 2 rides on the starting end of the conveyor 18.
Here, the first bogie sensor S1 detects the germination trolley 2 riding on the transport conveyor 18, and the transfer conveyor 18 operated in response to the detection signal causes the germination trolley 2 to float from the floor, and the transfer work position. (Detection position of second bogie sensor S2)

Then, in the greening truck transport section 5, a manual loading process in which an operator manually loads the greening truck 4 to the starting end of the transport conveyor 22, and automatically transports the manually loaded greening truck 4 to the reloading work position. Automatic carrying-in processing, and automatic carrying-out processing for automatically carrying out the greening trolley 4 on which the transshipment work has been completed to the terminal end of the conveyor 22;
By manually repeating the manual unloading process in which the operator manually unloads the automatically transported greening cart 4 to a predetermined position (greening chamber), the greening cart 4 is sequentially supplied to the transfer work position of the conveyor 22. It is supposed to. In other words, although the greening truck transport unit 5 has different dimensions and the like, the basic configuration and the processing procedure are substantially the same as those of the above-described sprouting truck transport unit 3. Invite.

[0013] Each of the trolley transport units 3 and 5 carries the trolleys 2 and 4 from the front side of the seedling box transshipment device 1 and transfers the completed trolleys 2 and 4 to the seedling box transshipment device. 1 is carried out to the rear side. That is, each carriage transport unit 3,
5 is one-way and straight, the flow line of the carry-in vehicle and the flow line of the carry-out vehicle do not overlap or intersect. Are parallel at a predetermined interval, so that the flow line of the budding trolley 2 and the flow line of the greening trolley 4 can be prevented from overlapping or intersecting. As a result, in the seedling box transfer process, It is not permissible to simplify the flow lines of the trolleys 2 and 4 to simplify the transportation work of the trolleys 2 and 4 by the operator, and it is possible to perform an efficient seedling box transfer operation in a minimum space. I can do it.

Further, in each of the carriage transport sections 3 and 5 of the present embodiment, the carriage transport direction can be appropriately reversed according to the installation environment of the seedling box transshipment apparatus 1. That is, it is possible to change the carriage transport direction by reversing the installation direction of the transport conveyors 18 and 22. However, in the present embodiment,
Since the transport conveyors 18 and 22 are configured to be installed independently on the floor surface, the transport direction of the trolley is changed as compared with the case where the transport conveyors 18 and 22 are integrally mounted on the seedling box transshipment apparatus 1. Can be easily performed.

The conveyors 18 and 22 include conveyor bases 18a and 22a which are in contact with the floor, and a pair of left and right driven sprockets 18b and 22b provided on the start side of the conveyor.
A pair of left and right driving sprockets 1 provided on the transport end side

It comprises chain guides 18e, 22e for supporting the tensioned side (upper side) of 22d from below, and conveyor driving motors 18f, 22f for driving the drive sprockets 18c, 22c, etc., but the chain support at the top of the driven sprockets 18b, 22b. The position is the chain guide 18e, 22
e is set lower than the chain support position at the start end of the chain guide. Therefore, in the chain movement path from the driven sprockets 18b, 22b to the start end of the chain guides 18e, 22e, the chain is inclined forward by a predetermined angle α. An inclined portion will be formed. That is, since the carriages 2 and 4 can easily climb onto the conveyors 18 and 22, workability when the carriages 2 and 4 are manually loaded on the conveyors 18 and 22 is improved.
Since the overall height of the carriage 22 is not low, the levitation height of the bogies 2 and 4 from the floor surface can be set as high as possible to prevent contact with obstacles on the floor surface. It has become.

The conveyor bases 18a, 18a,
At the start end of 2a, the rear ends of the above-mentioned approach guides 19 and 23 are fixed via a pair of left and right bolts 19a and 23a, but in a state where the bolts 19a and 23a are loosened,
Entry guide 1 with bolts 19a and 23a as pivot points
Since the occupants 9 and 23 can be stored in the upright posture at the rear upper side, inconveniences such as the entry guides 19 and 23 obstructing traffic during non-transfer work can be avoided.

The approach guides 19 and 23 guide the free casters 8 and 10 of the bogies 2 and 4 to a predetermined approach path by flange-like guide portions 19b and 23b formed on left and right outer portions. , Left and right guide portions 19b, 23b
Are integrally connected via the connecting portions 19c and 23c, so that the storing operation can be facilitated as compared with the case where the left and right guide portions 19b and 23b are formed independently, and strength is not increased. Is also advantageous, and furthermore, the entry guides 19, 23
Can cover the chains, sprockets and the like of the conveyors 18 and 22 from the front at the time of storage, so that it can also function as a safety cover.

The entry guides 19 and 23 guide the free casters 8 and 10 so that the carts 2 and 4 enter between the left and right roller guides 17 and 21 as described above. Are provided so as to enter between the roller guides 17 and 21 in plan view. That is, since the entry guides 19 and 23 overlap the roller guides 17 and 21 by at least one pitch of the roller, at least a plurality of rollers 17a and 21a are inserted after the carriages 2 and 4 enter between the roller guides 17 and 21.
Will support the sides of the trolleys 2, 4 and as a result,
The rollers 17a, 2a at the starting end are compared with those that may support the sides of the carts 2, 4 with a single roller 17a, 21a.
It is not possible to reduce the load acting on 1a, but it is possible to improve the positional accuracy of the carriages 2 and 4 transported by the transport conveyors 18 and 22.

The seedling box transfer unit 7 includes a seedling box removal unit 24 for removing the seedling box 6 from the germination cart 2 set at the transfer position of the germination carriage transport unit 3. And a seedling box insertion part 25 for inserting the extracted seedling box 6 into the greening truck 4 set at the transshipment operation position of the greening truck transporting unit 5. The details of each part will be sequentially described below.

The seedling box take-out section 24 is composed of a pair of front and rear guide rails 26a laid on the frame 11, and the take-out section frame 2 which is movable left and right along the guide rails 26a.
7. A pair of left and right seedling box gripping mechanisms 29 provided on the take-out section frame 27 via a lifting guide shaft 28 so as to be able to move up and down, and can move laterally in the front-rear direction with respect to the main body of each seedling box gripping mechanism 29; It is provided with a pair of front and rear seedling box grippers 30 and the like which are configured to be extendable and contractible.
Take-out unit laterally moving motor 31 for laterally moving 7 through a laterally moving chain 31a;
Mechanism for raising and lowering the seedlings via the raising / lowering chain 32a, and the above-mentioned seedling box gripping bodies 30 are connected to the telescopic chains 33a.
The actuator is driven by actuators such as a gripper expansion / contraction motor 33 that expands and contracts via a gripper and a gripper lateral movement cylinder 34 that horizontally moves the opposing seedling box gripper 30 in the approaching / separating direction.

The seedling box gripping body 30 is integrally extended from a ten-stage nail bracket 36 to which a pair of left and right seedling box gripping claws 35 are attached, a lowermost nail bracket 36 and another nail bracket 36. A pair of right and left telescopic guide shafts 37 for guiding the upper and lower slidable freely, each claw bracket 36
It is composed of a flexible connecting link 38 and the like interposed therebetween. The uppermost claw bracket 36 is integrally supported on the side of the laterally moving bracket 39 that moves laterally with the driving of the gripper laterally moving cylinder 34 described above,
The lowermost claw bracket 36 is provided with the telescopic chain 33 described above.
a, it is extended from the upper claw bracket 36 so as to gradually widen the interval along with the chain extension drive of the gripper extending / contracting motor 33, while the chain retracting drive of the gripper extending / contracting motor 33 is performed. Accordingly, the lower claw bracket 36
It will be reduced by gradually narrowing the interval from
In addition, the vertical interval of each seedling box gripping claw 35 at the time of extension,
It is set so as to substantially coincide with the vertical placement interval K3 of the seedling box 6 in the greening cart 4. Note that 35a is a locking projection that protrudes upward from the tip of the seedling box gripping claw 35,
When the seedling box gripping claw 35 is gripping the seedling box 6, the locking projection 35 a is provided with a flange 6 c so as to restrict the falling of the seedling box 6.
To lock the inner part.

Next, a procedure for removing the seedling box in the seedling box removing section 24 (control procedure of the control panel 20) will be described. However, in the initial state, the opposing seedling box gripping bodies 30 are separated from each other and are in a contracted state. First, a pair of left and right seedling box gripping mechanisms 29 is driven based on the driving of the take-out unit lateral movement motor 31.
Is moved laterally above the budding cart 2. Here, when four rows of seedling box groups A are placed on the germination trolley 2, the pair of left and right seedling box gripping mechanisms 29 move laterally to above the right two rows of seedling box groups A, while germinating. When the seedling box group A on the trolley 2 is the remaining two rows, the seedling box gripping mechanism 29 moves laterally to above the seedling box group A in the left two rows. After the lateral movement is completed, the pair of left and right seedling box gripping mechanisms 29 is lowered based on the driving of the gripping mechanism lifting / lowering motor 32, and then the seedling box gripping body 30 is moved to the side of the upper ten rows of the seedling box group A. At this stage, the lowering of the seedling box holding mechanism 29 is stopped. In the above description, the lowering operation is performed after the seedling box gripping mechanism 29 is laterally moved. However, the operation order may be reversed, and both operations may be performed simultaneously. is there.

Next, the seedling box holding body 30 is moved by a predetermined stroke in a direction approaching the seedling box group A based on the driving of the holding body lateral movement cylinder 34. Here, the seedling box gripping claws 35 of the respective nail brackets 36 enter the above-described gap K1 secured between the flange portions 6c of the seedling box 6, and are subsequently driven by the gripping mechanism elevating motor 32. When the pair of right and left seedling box gripping mechanisms 29 is raised, 10-stage seedling boxes 6 are simultaneously taken out of the two rows of seedling box groups A arranged in parallel. Then, the pair of left and right seedling box holding mechanisms 29 is connected to the seedling box 6.
After the removal, the pair of left and right seedling box gripping mechanisms 29 are laterally moved to the initial position on the right end based on the drive of the extracting unit lateral movement motor 31, and then the seedling box is driven by the gripping body expansion / contraction motor 33. The gripper 30 is extended to extend the vertical interval of the seedling box 6 to the interval K3.

In other words, the seedling box take-out section 24 simultaneously holds the seedling box group A placed on the budding cart 2 in a stacked manner,
In order to adjust the vertical spacing of the group A of grasped seedling boxes, the processing speed cannot be increased as compared with the conventional one in which the seedling boxes 6 are taken out one by one, and the structure can be simplified. Moreover, since a plurality of seedling box holding mechanisms 29 are arranged in parallel to simultaneously hold a plurality of rows of seedling box groups A, the processing speed can be further increased. In the present embodiment, when simultaneously holding the seedling box groups A in a plurality of rows, in the present embodiment, the right and left intervals of the seedling box holding mechanisms 29 are fixed to simplify the structure. Since the position of the box group A in the left-right direction is regulated by the seedling box guide 9, the inconvenience of lowering the accuracy of the seedling box removing operation can be avoided.

When a plurality of seedling box gripping mechanisms 29 are arranged in parallel, the plurality of seedling box gripping mechanisms 29 are configured to be laterally moved by a single take-out portion lateral movement motor 31 (lateral movement mechanism). As a result, the structure can be simplified and the number of parts can be reduced as compared with the case where each seedling box gripping mechanism 29 is laterally moved individually.
It is possible to reduce the size of the device.

Numeral 40 denotes a seedling box pressing member (seedling box pressing member) provided in each seedling box holding mechanism 29.
Is configured such that the upper portion of the seedling box group A is pressed downward when the seedling box holding body 30 grips the seedling box group A on the budding cart 2. That is, while pressing the upper part, the seedling box group A
In order to grip the seedling box 6, even if the seedling box 6 is floating due to budding, the vertical displacement of the gripping position (gap K1) can be corrected as much as possible, so that the seedling box 6 can be reliably gripped. .

The seedling box pressing body 40 includes a pressing roller 41 rotatable in the seedling box gripping operation direction (front-rear direction) of the seedling box gripping body 30, and a rod 42 for supporting the pressing roller 41 up and down. , A pressing roller 43 for pressing the pressing roller 41 toward the upper part of the seedling box group A, a spacer 44 for adjusting the pressing force of the pressing roller 43, and the like. That is, while pressing the upper part of the seedling box group A, the seedling box gripper 3
With respect to the seedling box gripping operation direction of 0, since the movement of the seedling box group A based on the rotation of the pressing roller 41 is allowed, the seedling box gripping body 30 is displaced in the seedling box gripping operation direction. When the seedling box group A is gripped, the seedling box pressing body 40 can restrict the movement of the seedling box group A to avoid the inconvenience of hindering the seedling box gripping operation.

A plurality (two in the present embodiment) of the seedling box pressing members 40 are provided at predetermined intervals in the front-rear direction with respect to the respective seedling box gripping mechanisms 29. Since the pressing rollers 41 of the seedling box pressing body 40 provided in the gripping mechanism 29 are connected via the connecting plate 45, necessary rigidity can be secured. A plurality of pressing rollers 41 are provided by pivotally connecting a pin 41b that penetrates the long hole 45a of the connection plate 45 to a roller bracket 41a of the roller 41.
Is connected, the proper independence of the expansion and contraction operation of each seedling box pressing body 40 cannot be maintained, and the connection plate 45 restricts the rotation of the pressing roller 41 around the rod axis. It can be used also as a rotation restricting member.

Reference numeral 46 denotes a peeling claw provided on the lowermost claw bracket 36. The peeling claw 46 is used when the seedling box holding body 30 is extended to widen the vertical distance between the seedling boxes 6.
The lower seedling box 6 is provided to prevent the state where the seedling box 6 remains attached to the upper seedling box 6. In other words, in the seedling box 6 that has been sprouted in a stacked state, the upper and lower seedling boxes 6 may become attached due to the growth of germinated seedlings. Since the pulling load is not applied by the seedling box 6 on the side,
Is engaged with the upper side of the flange portion 6c to forcibly peel off the lowermost seedling box 6. Therefore, as in the case where the seedling box reloading operation is continued while the lowermost seedling box 6 is attached, the seedling box 6 is dropped or clogged, and the operation is interrupted.
It is possible to eliminate the inconvenience of taking time for the recovery work.

On the other hand, the seedling box insertion section 25 is
1, a pair of front and rear guide rails 26 b laid on the top, an insertion portion frame 47 movable left and right along the guide rails 26 b, and an elevating guide shaft 4 mounted on the insertion portion frame 47.
8, a table body 49 that can be moved up and down freely through
10-stage fixed table 50 provided on the table body 49 at predetermined intervals in the vertical direction, and two seedling boxes 6 that can be moved horizontally in the horizontal direction on the fixed table 50 and are arranged side by side.
And a motor 5 for horizontally moving the insertion section frame 47 in the left-right direction via a horizontal movement chain 52a.
2. Actuates based on actuator drives such as a table elevating motor 53 for elevating and lowering the table body 49 via an elevating chain 53a, and a table lateral moving cylinder 54 for laterally moving the lateral moving table 51. The guide rail 26b guides the take-out part frame 27 of the seedling box take-out part 24 so as to be movable left and right.
The same rail member 26 as a is used. That is, since the take-out unit frame 27 and the insertion unit frame 47 are supported by the same rail member 26 that is linearly continuous so as to be able to move laterally, the number of parts can be reduced and the structure can be simplified. In addition, it is possible to avoid a relative positional shift between the take-out unit frame 27 and the insertion unit frame 47 due to a rail mounting error.

Next, a procedure for inserting a seedling box in the seedling box insertion section 25 will be described. However, in the seedling box removal section 24, two rows of seedling box groups A with an increased vertical spacing are on standby, while in the seedling box insertion section 25, the laterally moving table 51 is connected to the fixed table 50 by the end of the fixed table 50 near the seedling box removal section ( (Left end). First, the table body 49 is laterally moved to the seedling box take-out part 24 side based on the driving of the insertion part lateral movement motor 52. Here, each of the horizontal moving tables 51 enters the space secured between the upper and lower seedling boxes 6, and subsequently, the table body 49 is raised by a predetermined stroke based on the driving of the table lifting motor 53. The two seedling boxes 6 in which the lateral movement tables 51 are arranged side by side at predetermined intervals K2 on the left and right sides are simultaneously scooped from the seedling box holding mechanism 29. Next, the table body 49 is driven based on the driving of the insertion portion lateral movement motor 52.
Is moved to the greening truck 4 side, and the horizontal moving table 51 is moved to the greening truck side end (right end) of the fixed table 50 based on the driving of the table horizontal moving cylinder 54. The two seedling boxes 6 on 51 are to be inserted into the respective mounting shelves 4b of the greening cart 4, and then the table body 49 is lowered by a predetermined stroke based on the drive of the table elevating motor 53. Thus, the two seedling boxes 6 are placed on the respective shelves 4b.

That is, the seedling box insertion section 25 is connected to the seedling box extracting section 2.
In order to simultaneously scoop up the two rows of seedling box groups A held by 4 and mount them on the mounting shelf 4b of the greening cart 4, the seedling boxes 6 taken out one by one are arranged vertically. The processing speed cannot be increased as compared with the conventional one inserted into the greening cart 4, and the structure of the apparatus can be simplified. In order to place the seedling boxes 6 in a row in close contact with the greening cart 4 with the predetermined spacing K2 secured between the seedling boxes 6 in the row, the floor soil may be offset. It is not allowed to avoid inconvenience, but it is also possible to improve lighting and irrigation in the greening process.

As described above, the seedling box insertion section 25 performs the overall lateral movement of the table body 49 and the relative lateral movement of the lateral movement table 51 with respect to the table body 49 in a combined manner. The seedling box 6 is configured to be inserted into the greening cart 4. As a result, the horizontal movement stroke of the table body 49 can be reduced to reduce the size of the apparatus. Based on the proper operation speed setting of 51, the processing speed can be increased while suppressing the impact given to the seedling box 6.

In the present embodiment, when the table body 49 and the laterally moving table 51 are laterally moved in a complex manner, in the present embodiment, the table body 49 is prevented from accelerating and decelerating due to stopping, and the table body 49 is not fixed. At the time of high-speed movement, the horizontal movement table 51 is moved laterally. That is, since the acceleration or deceleration timing of the table body 49 and the lateral movement table 51 is avoided from being coincident, the impact on the seedling box 6 during the lateral movement can be minimized. The quality of the seedlings can be prevented from deteriorating due to bias or the like.

In addition, the table horizontal movement cylinder 54
Employs a rodless cylinder that moves a movable portion 54b protruding from a cylinder body 54a by air pressure. And, since the rodless cylinder can constitute the table lateral movement mechanism by itself, it constitutes a compact and simple table lateral movement mechanism as compared with the case of employing a transmission mechanism such as a chain mechanism, a rack and pinion mechanism, and a ball screw mechanism. You can do it.

The table lateral movement cylinder 54
In the present embodiment, when the horizontal movement table 51 is moved laterally, the table horizontal movement cylinder 54 is mounted along the upper surface of the fixed table 50, and the movable portion 54b of the table horizontal movement cylinder 54 is moved to the horizontal movement table 51.
The casters 51a which roll on the upper surface of the fixed table 50 are provided at the bottom of the horizontal moving table 51.
Is provided, the lateral movement load received by the table lateral movement cylinder 54 can be reduced, and as a result, a small rodless cylinder cannot be adopted. Can be improved. Reference numeral 50a denotes a pair of front and rear guide rails 50a provided on the upper surface of the fixed table 50 to guide the casters 51a.

The components of the seedling box transshipment apparatus 1 have been described above. The seedling box transshipment apparatus 1 thus constructed is described above.
In, the seedling box transfer transfer path from the germination trolley 2 of the germination trolley transport unit 3 to the greening trolley 4 of the greening trolley transport unit 5 is substantially straight in plan view. Therefore, it is not possible to simplify the flow line of the seedling box 6 in the seedling box transfer process to improve the processing capacity, and it is possible to prevent the floor soil from shifting and improve the quality of the seedling. In addition, in the present embodiment, the germination trolley transport unit 3, the seedling box transfer unit 7, and the greening trolley transport unit 5
Are arranged in a substantially straight line in the frame 11, so that the moving distance of the seedling box between the parts can be shortened to improve the processing capacity, and the front and rear width of the seedling box transfer device 1 is made as large as possible. It becomes possible to make it smaller.

In providing the seedling box extracting section 24 and the seedling box inserting section 25 in the frame 11, in the present embodiment, the long side of the seedling box 6 is provided below the seedling box extracting section 24 and the seedling box inserting section 25. A gap K4 of approximately the same size is ensured. Therefore, even if there is a problem that the seedling box 6 falls off from the seedling box extracting section 24 and the seedling box inserting section 25, the seedling box extracting section 24
And the seedling box 6 between the seedling box insertion part 25 and the floor.
It is not possible to avoid secondary troubles such as pinching of the seedlings, but it is also possible to improve the maintainability by enabling inspection, adjustment, and the like from below the seedling box extracting section 24 and the seedling box inserting section 25. I can do it.

The actuators of the above-described components are all controlled centrally by the control panel 20. The control program incorporated in the control panel 20 includes a budding carriage transporting section 3, a seedling box extracting section 24, a seedling box It is described that the insertion section 25 and the greening truck transport section 5 are independently operated. For this reason, it is possible to individually set the processing timing and processing speed of each unit, and as a result, it is possible to perform efficient seedling box transfer processing by eliminating waste such as processing waiting time as much as possible. Not to be forgiven, the quality of the seedlings can be improved based on appropriate processing speed settings of each part.

The control panel 20 is connected to an alarm lamp (not shown) corresponding to the budding carriage transport unit 3, the seedling box removal unit 24, the seedling box insertion unit 25, and the greening carriage transport unit 5. When a trouble occurs in any part, the control panel 20 determines the trouble part and turns on a corresponding alarm lamp. For this reason, it is possible to easily specify the location where the trouble has occurred, as compared with the case of simply displaying an error code or the like, and as a result, it is possible to promptly respond to the occurrence of the trouble.

In the apparatus constructed as described above, the seedling box transshipment apparatus 1 includes a plurality of seedling boxes 6 mounted on a germination cart 2 for performing a germination process, and a greening cart 4 for performing a greening process. The seedling box transfer device which transfers the budding trolley 2 for which transshipment work has been refrained from the seedling box transfer device 1 and unloads the germination trolley 2 after the completion of the transfer operation. 3 and a greening truck transport unit 5 for carrying in the greening truck 4 for which transshipment work has been scheduled and for carrying out the greening truck 4 for which transshipment work has been completed.
In providing the seedling box 6 from the germination cart 2 of the germination cart transport unit 3 and the seedling box transfer unit 7 for placing the extracted seedling box 6 on the greening cart 4 of the greening cart transport unit 5, Since the seedling box transfer transfer path from the germination trolley 2 of the germination trolley transfer section 3 to the greening trolley 4 of the greening trolley transfer section 5 is substantially straight in plan view, the flow line of the seedling box 6 in the seedling box transfer processing is reduced. Not a forgiveness that can simplify and improve processing power,
The quality of seedlings can be improved by preventing displacement of the floor soil and the like.

Further, since the carriage transport directions of the carriage transport units 3 and 5 are one direction and are parallel to each other with a predetermined interval, the flow lines of the carriages 2 and 4 in the seedling box transfer process are simplified. Therefore, it is not possible to simplify the work of transporting the carts 2 and 4 by the worker, and an efficient seedling box transfer operation can be performed in a minimum space.

The seedling box transshipment unit 7 includes a seedling box extracting unit 24 that extracts the seedling box 6 from the germination cart 2, and a seedling that mounts the seedling box 6 inherited from the seedling box extracting unit 24 on the greening cart 4. A box insertion section (seedling box placement section) 25 and a budding carriage transport section 3, a seedling box removal section 24, a seedling box insertion section 25, and a greening carriage transport section 5 are operated independently of each other. The processing timing and processing speed can be set individually, and as a result, it is not possible to perform efficient seedling box transfer processing by eliminating waste such as processing waiting time as much as possible, The quality of the seedlings can also be improved based on the appropriate processing speed setting of each part.

The present invention is, of course, not limited to the above-described embodiment. For example, as shown in FIG.
5b may be formed. In this case, the seedling box holding claws 35
Has a sharp shape, so that the allowable range of positional deviation of the seedling box 6 with respect to the seedling box holding claw 35 can be expanded. In the above-described embodiment, the seedling box holding claw 35 is attached from the inside of the claw bracket 36. However, as shown in FIG. 14, the seedling box holding claw 35 may be attached from the outside of the claw bracket 36. In this case, there is an advantage that the position of the seedling box gripping claw 35 can be adjusted (such as height adjustment) while the seedling box 6 is held. Also, as shown in FIG.
A locking claw 51b for locking the end of the seedling box 6 may be provided at the end of the lateral movement table 51. In this case, the displacement of the seedling box 6 due to vibration or the like can be regulated. It is possible to prevent an incorrect insertion into the greening cart 4 due to the displacement.
