Description

[0001] The present invention relates to an automatic direction changing unit for moving a base plate in three directions,

The present invention relates to a transfer device for transferring an ornamental plate in a nursery, in which a seedling plate transferred at a constant speed is maintained at a constant speed while being switched in direction, And an automatic direction switching unit.

In particular, the present invention relates to a method for forming a gas-filled frame in which a plane is formed in a "T" shape and has three directions, i.e., first, second and third directions, The plate can naturally move in the opposite direction to move at the same speed so that the traffic jam phenomenon does not occur at all while the direction is switched so that the stable transportation operation can be realized. Unit.

Generally, the base plate is a badge for seedlings, and it is a badge to grow seedlings that are necessary for the simulation work.

The planting work is a kind of manual work, but it is practically impossible to plant the seedlings in the rice field in spring when planting the rice plant. In other words, the seedlings are grown to a certain size, and the seedlings are cultivated in such a way that only seedlings that have been nurtured to some extent and raised their own abilities are moved to the rice field.

In other words, in order to reach the rice paddy, the nursery is raised according to the method set in the place where the seedling is raised for a certain period. The present invention relates to a transfer device of a base plate installed in a nursery, which is raised during self-sustaining period, and a direction switching unit which is a part of a transfer system of transferring the base plate.

As shown in FIG. 1 (domestic patent No. 10-2000-0040895; rice seedling-saving box method and seedling box), seedlings are planted in a seedling plate, The environment will raise about 8 days. The temperature condition is about 36-40 ° C. After this period, the seedlings change color in yellow, and in this state, they are taken out to the shaded room, which is the shielded space, and only water is added to the room temperature for 3-6 days. After that, seedlings are changed into greenish sprouted seedlings. After that, they are taken out to the nursery and grown for 4-8 days in the sunlight. The sun that received the sunlight is placed in the nursery in the state of being seated inside the basin of Fig. 1, which is actually the same as the rice field. The seedlings grow more healthily through the sunlight on a row of piles. Each farmer then buys them and grows up his own rice field, grows rice, grows rice, and then produces rice.

In the past, most of the nurseries are mainly in the greenhouse, supplying water for cutting seedlings and cutting off the light. In order to shoot the sunlight, it is necessary to take out the seedling plate inside the greenhouse to the outside nursery . This work is quite difficult. Every one should take out the nursery plates and spread them one by one to lay them on the nursery. In fact, only the manual work of man is used to carry all the nursery plates because the seedlings die and can not overlap because they are rolled up. Although there are existing automated facilities, many problems arise in the process of being transported. If only one of them lose their velocity during transport, they hit each other in succession, interfere with the transport of the other seedling plates, and become like a domino and become broken and destroyed.

Therefore, in the case of most conventional conveyor belt conveying means, it is necessary to develop a precise and stable development of a direction switching unit for changing the direction. A direction switching unit used for conveying a long conveying belt of about 50-100 m or longer, The development was more difficult. However, the present invention completely solved the problem.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction changing unit which is a part of a feeding apparatus installed in a nursery.

Therefore, the configuration of the present invention and the operation thereof will be described in detail with reference to FIG. 2 through FIG.

As shown in the drawings, the present invention is directed to a direction switching unit that allows a base plate 7 or various boxes to be moved on a conveyor in one direction to be conveyed in a horizontal direction by 90 ° and 180 °, A gas frame 50 formed in a first direction (I), a second direction (II), and a third direction (III), each extending at an angle of 90 degrees; 2 and 3 in the direction of the first, second and third directions (I, II, III) from the central portion side of the base frame 50 so that the outer periphery of the rolls protrudes above the base frame 50, 54) a first roll (51, 53) engaged; Is fixed between the interlocking bars 57 which are axially coupled to the end frames of the first, second and third directions I, II, and III so as to correspond to the first rolls 51 and 53, A counter roll 58; Three change-over belts 61 wound around the outer circumferential surfaces of respective corresponding rolls 58 corresponding to the three first rolls 51, 53; And sprockets corresponding to separate sprockets fastened to the shafts 52 and 54 of the first rolls 51 and 53 fastened to the center of the base frame 50, M2 and M3 in the direction of the direction changing unit K so that the base plate 7 or the box moving along the conveyor belt 12 is moved in the direction of one side of the direction switching unit K, And then to be transferred to the other conveyor belt 12 in the other direction.

For reference, in the drawing of the present invention, the first roll 51 forming the first and second directions I and II is denoted by 51 in the drawing, and the first roll 51 forming the third direction 53 1 roll 53 is denoted by 53 in the figure. This is for no particular reason, but merely to make the description of the drawings more distinguishable so that the division of direction is made clear.

That is, the present invention is used when the base plate 7 and various boxes are to be conveyed through the conveyor belt 12 and the conveyance is to be continued at a different angle by switching the direction. The transfer of the moving object has its own inertia, so that it often happens that there is a flock in the process of switching the direction. Therefore, it is necessary to maintain the conveying speed even after the direction is changed, and all of the bases 7 or boxes inserted in the conveying process must always face the destination of the conveyance accurately, It should not be rolled inside. But achieving these conditions is not easy. In particular, as in the present invention, careful and accurate operation must be performed in order to transfer the base plate 7 planted with the seedling 6 and to change the direction again. The direction switching unit (K) of the present invention is a breakthrough invention including all of these considerations.

Before explaining the process of the operation of the direction switching unit K of the present invention, the nursery 8 and related overall technical matters will be described to explain how to use the direction switching unit K.

(8) Nursery plate (5) The feeding system of the feeding device is simple. As shown in Figs. 2 and 3, the first conveyor conveying path 10 and the second conveyor conveying path 20 shown in the left and right sides of the rice paddy of the nursery field 8 formed by the elongated rice paddies are installed. 2, a greenhouse H is installed on the side of the first conveyor transfer path 10, but it is also possible that a greenhouse H is installed on the side of the second conveyor transfer path 20 in a substantially opposite direction. In the greenhouse (H), seedlings are grown at a temperature of about 34-40 ° C for about 8 days. In other words, the value of the seed (= seedling) increases according to the number of days cultivated in the nursery (8). The seedlings purchased by the farmers for the transplant actually grow after the first growth of the greenhouse (H), and the second growth of six days in the shade. In fact, seedlings can be sold to farmers since the second growth. Of course, after the shading room, a farmer who wishes for more expensive but more self-sustaining seedlings grows in this greenhouse (H) and shading room, and grows more seedlings in the nursery (8) with sunlight.

Therefore, the nursery (8) system requires the nursery (8) to improve the quality of the goods as well as the greenhouse (H). For this reason, the nursery conveyor 8 of this invention uses the first, second, and third conveyor conveyors 10, 20, 30 in various manners.

If a farmer chooses a seedling raised in a greenhouse when ordering seedlings for transplantation in the nursery (8), the transfer device containing the invention operates as follows. When the driving motor M is rotated, the driving motor M drives the connecting path 80. The connecting path 80 extends outward from the greenhouse H and is connected to the first conveyor conveying path 10 as shown in Fig. Therefore, the operator performs an operation of placing the plate 7 on the upper portion of the connecting path 80 from the greenhouse H. This operation is carried out on the conveyor belt 12 to the outside of the connecting path 80 and moves to the first conveyor conveying path 10. In the drawing, part A, which is the important part, is the part to which the conveyor belt 12 is vertically connected. In this part, it is necessary to pay considerable attention to the movement in the perpendicular direction. Only when the direction is changed and the vehicle (= cargo truck) 9 stops at the end of the first conveyor conveyance route 10, the bed plate 7 moves toward this portion. Then, through the simple work, the car is completed.

On the other hand, if the seedlings are to be planted for a certain period of time in the greenhouse, and then the seedlings are exposed to the sunlight, a plurality of seedlings (5) And travels on the conveyor conveying path (10). The third conveyor conveying path 30, which is mounted on the inner side of the transformer structure T, is moved. The worker moves from the inside of the nursery school 8 to his position and places the nursery plate 5 on the inside of the nursery school 8. Then, after being cultivated for a certain period of time, the seedlings (6) cultivated in the sunlight are transferred to the farmer who has purchased them. Even in this case, the present invention transfers the base plate 7 only by changing the direction.

That is, the operator transfers the trans structure T to the position where the fastest sales should be made. In the drawing, the direction is indicated by the x-axis coordinate and the y-axis coordinate, and the movement of the x-axis coordinate proceeds. When the operator moves in the X1 direction and the X2 direction and takes an accurate position, the worker grasps the base plate 7 which has been nurtured inside the nursery 8 and places it on the third conveyor conveying path 30 at the upper position. To the third conveyor conveying path (30) placed inside the trans structure (T). When this operation is completed, the third conveyor conveying path 30 is moved to a position where the vehicle 9 is stopped, that is, to the end of the first conveyor conveying path 10 or the second conveyor conveying path 20, Move to the selected location. The direction changing unit K is formed at both ends of the third conveyor conveying path 30 so that the conveying of the first and second conveyor conveying paths 10 and 20 is performed in the third conveyor conveying path 30, This is flexible. When this transfer is made, transfer of the seedlings plate 5 to the vehicle 9 is easy.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. In the present invention, the first, second, and third conveyor conveying paths 10, 20, 30 and the connecting path 80 for conveying the seedling plate 5 through the conveyor belt 12 are substantially the same combination of components to be. That is, there are a rail frame 15 which is extended in both left and right ends and which is installed in a parallel line shape at regular intervals in the longitudinal direction. Inside the rail frame 15, a plurality of belt rolls 11 ). There are also a number of conveyor belts 12 around the outer periphery of the belt roll 11 and surrounding a plurality of belt rolls 11 in the same longitudinal direction as the rail frame 15, And a plurality of drive motors M, chains and sprockets (not shown) installed to rotate the conveyor belt 12 through a certain combination. Therefore, when the driving motor M rotates the belt roll 11 on one side, the belt roll 11 on one side rotates and the incubation plate 5, which is seated on the upper end of the conveyor belt 12 interlocked with the outer circumferential surface, To a desired place.

In addition, the movement of the transformer structure T is important for the seedlings 5 to undergo a growth process using sunlight in the nursery 8. That is, the trans structure, which assists the operation of the present invention and on which the orientation changing unit of the present invention is mounted, is an important component of its own. As shown in Figs. 3 to 6, the trans-structure T on which the third conveyor conveying path 30 is seated is connected to the plurality of vertical frames 22 and the horizontal frame 21, The conveyor rolls 38 integrated with the lower leg frames 25 at both the left and right ends of the conveyor rollers 10 and 20 are seated on the rails 19; When the power generating unit KT operates the rotating motor 31, the feed roll 38 rotates to ride on the rail 19 so that the trans structure T can move in the nursery in the left and right direction.

As described above, the trans structure T serves as a leg connecting the right and left ends of the nursery 8, and the left and right ends of the transformer structure T are connected to each other by a separate direction switching unit K, The X axis movement shown in Fig. 2 can be achieved. So that the inside of the nursery (8) can be fully utilized. This is a structure in which a plurality of horizontal frames 21 and vertical frames 22 are welded to a transformer structure. This has a rail frame 15 on which a third conveyor conveying path 30 can be mounted.

That is, the trans structure T of the present invention can move in the X-axis while the third conveyor conveying path 30 is mounted. This is because of the leg frame 25 and the carriage 26 formed at the right and left ends of the trans structure T. The leg frame 25 is a substantially vertical frame 22 descending from the left and right ends of the trans structure T to the lower ends thereof. At the lower end of the leg frame 25 is formed a bogie 26 which is seated on the top of the rail 19 with the illustrated bogie roll 38 fastened.

The rails 19 are different from the levels of the first, second and third conveyor conveyors 10, 20 and 30. As shown in Fig. 4, the first and second conveyor conveying paths 10 and 20 are mounted at the tops of the paddles maintaining the level of the flatness t or somewhat higher. On the other hand, the rail 19 is mounted on the nursery field 8, that is, on the ground surface 7-1 of the rice field. The rail 19 is of the same or similar construction as the rail 19 of the train and guides the trans-structure T so that it can move along this rail 19. [ A transfer roll 38 formed on the carriage 26 is seated on the rail 19 and the transfer structure T is moved on the rail 19 when the transfer roll 38 is rotated. For reference, details of the transfer apparatus including the present invention can be found in the "automatic transfer apparatus for seedlings for seedlings on the base plate", which is filed by the same inventor and the same inventor.

In this case, the operation mode of the direction switching unit K, which is included as part of the conveying device and performs the most important operation, will be described. The redirection unit K of the present invention is formed in the rounded block B portion shown in Fig. More precisely, at both ends of the left and right sides of the trans structure T, respectively. As shown in FIGS. 2 to 8, the transformer structure T has a transverse structure T which is seated on the left and right ends of the transverse structure T, that is, the upper portion of the first and second conveyor conveying passages 10 and 20, A direction switching unit K for converting the motion of the base plate 7 to a position (= B point) The direction switching unit (K) is substantially integrated with the transformer structure (T); The base plate 7, which has the movement path of the "T" course and moves on the direction switching unit K, is capable of switching motion in three directions freely.

The reason why the direction switching unit K is essential in the present invention is as follows. 2, the third conveyor conveying path 30 and the first and second conveyor conveying paths 10, 20, which are mounted on the trans-structure T, Always be able to communicate. For example, the ornamental plate 5, which has been moved on the first conveyor conveying path 10, is moved to the third conveyor conveying path 30 after climbing on one side direction switching unit K of the transformer structure T, There is a case in which the first conveyor conveying path 10 must be moved up again beyond the base frame 50 of the unit K. [ The trans structure T has a substantially high level because it serves as a bridge connecting the first and second conveyor conveying paths 10 and 20. In order to achieve such a difficult directional change, as shown in Fig. 9, the ornamental plate 5 rides on the first conveyor conveying route 10 to one side of the direction switching unit K (in Fig. 9, II)} (see Fig. 9A). At this time, the changeover belt 61 in the second direction II, which is tapered downward to the first conveyor conveying path 10, receives the ornamental plate 5.

The switching belts 61 of the first, second, and third directions I, II, and III provided in the present invention are arranged in the center of the base frame 50 of the direction switching unit K, The rolls 58 corresponding to the first, second and third directions are rotated around the first rolls 51 and 53 while being connected to the respective rolls 59 Rolls around the outer circumferential surface of the roll 60. Accordingly, the first rolls 51 and 53 and the corresponding rolls 58 and 53 are driven through the respective motors M1, M2 and M3, which are separate motors, in the first, second and third directions I, The switching belt 61 is rotated to receive the seedling plate 5 from the first conveyor conveying path 10 and the gasket frame 50 As shown in Fig.

9 shows a guide plate 63 which is separately fastened for guiding the direction change. The guide plate 63 is formed in a smoothly rounded shape, and guides the edge of the introduced seedlings plate 5 And to the other direction. To assist in this guide, the direction switching unit K of the present invention transfers power to the shafts of the first rolls 51 and 53 by separate motors M1, M2 and M3 as shown. Therefore, in Fig. 9, the user exits in the third direction (III) (as shown in Fig. 9C). This allows the third conveyor conveying path 30 to enter the end portion in the third direction III.

At this time, there are the first roll 51 and the corresponding roll 58, the connecting roll 60 and the contact roll 59 forming the first direction I shown in the figure, Thereby preventing power waste and stopping the transfer operation.

On the other hand, in this type of operation, in the direction changing unit K of the "T" shape, the seedlings 5 entering in the first direction I are guided to go out in the second direction II And it is easy to change the direction so that the starting point can be entered in the third direction (III) and exit in the first and second directions (I, II).

The detailed configuration and operation of the redirecting unit of the present invention will be described below. As shown in the drawing, the present invention is characterized in that the interlocking bar 57 is interposed between the end frames of the first, second and third directions (I, II, III) And a corresponding roll 58 extending from the shaft 56 and horizontally fastened to the outer side of the interlocking bar 57 is provided at the corresponding roll 58 coupled to the shaft 50 and the shaft 56, Tightening rolls 59 are fixed to the lower ends of the corresponding rolls 58 at predetermined intervals so as to be fastened between the interlocking bars 57 and to the left and right sides respectively, A separate connecting roll 60 is formed only between the end of the interlocking bar 57 and the interlocking bar 57 and then the switching belt 61 is wound around the connecting roll 60 at the outer peripheral surface of the first rolls 51, To the outer circumferential surface of the housing; An interlocking bar 57 having a narrow connecting roll 60 is sandwiched between the conveyor belts 12 formed in the first, second and third conveyor conveying paths 10, 20 and 30 for conveying, 20 or 30 from the base frame 50 of the direction changing unit K to the conveyor conveying path 10 or 20 or 30 or from the conveyor conveying path 10 to the inside of the base frame 50 of the direction switching unit K Make sure that there is no problem with the transportation. For reference, as described above, the first roll 51 forming the first and second directions I and II in the drawings of the present invention has the reference numeral 51 in the drawing, and the first roll 51 in the third direction 53 are denoted by reference numerals 53 in the drawing. This confirms that there is no particular reason but that the description of the drawings is made more distinct so that the division of directions is made clear.

In the structural pivoting method of the present invention, the three independent first rolls 51 and 53 rotate respectively, and this rotation rotates the respective change-over belts 61, The other rolled rolls were also rotated to actually rotate a number of rolls through a single power. It should be noted here that the contact rolls 59 and the connecting rolls 60 are continuously fastened to the lower end of the corresponding rolls 58. In the case of the counter roll 58, there is a corresponding roll 58 of the center portion around which the change-over belt 61 rolls, and a corresponding roll 58 whose axes extend to engage in a left-right pair. In the case of the corresponding roll 58 formed in the central portion, the power is transmitted through the changeover belt 61 to provide the power to move the direction in which the seedlings 5 and the box are seated on the upper portion thereof, The roll 58 has virtually no turning power. This serves as a guide roll that the box 6 can be evenly moved. When the center supporting roll 58 providing the power is pulled out of the box or the seedling plate 5, the same rotation is maintained in order to prevent the direction or the turning of the box, and serves as a guide for stable movement.

In order to achieve this substantially, in the present invention, an interlocking bar 57 is formed at the left and right ends of the corresponding roll 58 of the central portion. The shaft (= shaft) 56 of the corresponding roll 58 is fitted to the interlocking bar 57. The corresponding roll 58 at the center and both the left and right ends of the corresponding roll 58 has the same axis. Eventually, they will rotate at the same speed at the same speed.

The corresponding roll 58 has the same diameter as the other adjacent roll 59 and the connecting roll 60 fastened to the link bar 57. If the corresponding roll 58 is fastened to the upper end of the interlocking bar 57, the tightening roll 59 is fastened to its stop. It is actually concluded in the interlocking bar 57, but the level is different. In detail, in the case of the interlocking bar 57, the shaft 56, which is sandwiched by the corresponding roll 58 at its uppermost end, acts substantially as a hinge. And the interlocking bar 57 is rotatable about the hinge. 9, when the operator intends to move the seedlings 5 from the second direction II to the third direction III, the operation in the first direction I is substantially stopped . Therefore, the direction of operation is (II, III) in the second and third directions. The motors M2 and M3 which provide power in the second and third directions II and III are turned on and the motor M1 which is the power of the first direction I is cut off.

It is further preferable that the power control method of another type is such that the interlocking bar 57 is lifted up to the upper portion of the conveyor belt 12 as shown in Fig. That is, when it is necessary to switch the direction more quickly than the operation time for stopping the rotation of the motors M1, M2 and M3 in the course of the operation, the necessary interlocking bar 57 is lowered, And the interlocking bar 57 in an unnecessary direction is raised so as to block the movement of the ornamental plate 5.

The manner of operation of this invention will be described in more detail. 5, the direction switching unit K of the present invention is installed at the right and left ends of the transformer structure T, of which units installed on the first conveyor conveying path 10 are shown. In the case of the first and second directions (I, II), the direction switching unit K of the present invention is not in a form coupled to the first conveyor conveying path 10, Since it is fastened to the structure (T), a block process is performed to express this. Of course, this point will be described, and in the next figure, FIG. 7, the figure is shown in the other direction, i.e., in the first direction (I) (I) between the seedling plate 5 and the box. 8 shows a plan view of the direction switching unit K. As shown in this drawing, the direction switching unit K of the present invention has a body formed in a "T" shape The direction can be switched in three directions. FIG. 8 shows a transfer mode between the first and third directions I and III, and FIG. 9 shows a transfer mode between the second and third directions II and III. In this way, the present invention is advantageous in that the movement is changed in various directions.

If the operator intends to enter the seedling plate 5 in the second direction II as shown in Fig. 9 and to discharge the seedling plate 5 in the third direction III as shown in Fig. 9, The connecting rolls 60 at the ends of the interlocking bars 57 are installed so as to be laid on the lower end of the conveyor belt 12 by lowering the interlocking bars 57 provided in the second and third directions II and III. 8 is not inserted deeply into the lower end of the conveyor belt 12, but in use, it is pushed by the lower end of the conveyor belt 12, as shown in FIG. 10, (57) to maintain the oblique angle.

Returning again, the transfer process of FIG. 9 will be described. The seedling platter 5 which has traveled on the conveyor belt 12 of the third conveyor transport path 30 enters the upper part of the connecting roll 60 in the second direction II of the direction switching unit K. The tie-up rollers 61 are lifted up at an oblique angle and are lifted up to the corresponding rolls 58 at the uppermost end by the stopper rollers 59 of the interlocking bars 57 to maintain the horizontal state. That is, the tapered direction changing unit K is located above the base frame 50 of the tapering direction switching unit K and is positioned at the top of the flat base frame 50. 9, the first rolls 51 and 53 for determining the three directions I, II, and III are provided on the upper surface of the base frame 50 in the present invention. As described above, The first roll 51 in the first direction I is in a stopped state. It does not give any force to the bottom of the seedling plate 5 which is pushed up without rotation. On the other hand, the first roll 51 in the second direction II continues to apply the force until now and pushes up the ornament plate 5, and the first roll 51 in the second direction The roll 53 is rotated by the first roll 53, the corresponding roll 58, the close-contact roll 59 and the connecting roll 60 toward the third conveyor transfer path 10 on the other side. The eccentric force for changing direction is applied to the movement of the ornamental plate 5. In addition, the present invention further includes a guide plate 63 shown in order to facilitate the direction change of the ornamental plate 5. It is possible to connect the operator in a desired direction in a detachable form. If the direction switching unit K maintaining the communication in the first and third directions I and III as shown in FIG. 8 is to be converted into communication in the second and third directions (II, III) as shown in FIG. 9, The operation of the motor M for actuating the first direction I is stopped and the interlocking bar 57 is elevated in the first direction I to interrupt the connection with the conveyor belt 12. [ Next, the motor M for rotating the first roll 51 in the second direction II is operated while the interlocking bar 57 in the second direction II is moved to the lower end of the first conveyor conveying path 10, To push it in. After the connecting roll 60 is allowed to descend downwardly to the lower end of the conveyor belt 12, the guide plate 63 of FIG. 8 is disassembled and the direction of the guide plate 63 is changed as shown in FIG. It is possible to switch directions with very simple operation.

The guide plate 63 described above is provided on the upper portion of the base frame 50 of the direction switching unit K so as to guide a moving direction of the base plate 7, The first and third conveyor conveying paths 10, 30 (in the direction indicated by the arrows in the figure) for guiding the more reliable seedling plate 5, (Not shown) having elasticity for guiding the seedlings plate 5 on both the left and right sides can be further provided to carry out the safer seedling plate 5 feeding operation.

Next, the present invention is characterized in that the interlocking bar 57, which forms the extended ends of each of the first, second and third directions I, II, III, can manually rotate the shaft 56 with a hinge A tension adjusting roll 70 is provided on the inside or outside of each of the change-over belts 61 to adjust the tension of the change-over belt 61, Thereby improving durability.

10 shows a side view of the direction switching unit K according to the present invention. The combination of the switching belts 61 forming the respective directions, that is, the first rolls 51, 53, the corresponding rolls 58 ), The connecting roll 60, and the close-contact roll 59, another tension adjusting roll 70 is provided. In the case of the changeover belt 61, a tension adjusting roll 70 for adjusting the tension is formed to have a high tensile strength due to long use, so that the tensioning roll 70 always has a uniform tension.

Finally, in the case of the present invention, the first, second and third conveyor conveying passages 10, 20 and 30 are interlocked with each other in order to allow the connecting roll 60, which is descended by the interlocking bar 57, Forming a conveyor belt (12) on both sides of the bar (57) in such a manner as to be able to receive a gap therebetween; When the connecting roll 60 of the interlocking bar 57 is fitted to the lower ends of the conveying passages 10,20 and 30, the outer contact roll 59 of the interlocking bar 57 interrupts closely to the conveyor belt 12, So that the roll 59 can be rotated in the moving direction; So that the box 7 moving to the conveyor conveying paths 10, 20, 30 and the direction switching unit K and the box can always be stably moved.

That is, the direction switching unit (K) of the present invention relates to a direction switching unit (K) for switching the direction while moving back and forth while being integrally fastened to the transformer structure (T). Therefore, it is difficult for the present invention to separately provide the operation mode of the direction switching unit K alone. The first, second, and third conveyor conveyors (10, 20, 30), which are used together and must produce the same effect even if they are moved a certain distance, must be correlated with each other. To this end, the present invention adopts a configuration for forming the interlocking bar 57, so that two conveyor belts 12 formed on the first, second and third conveyor conveying paths 10, 20 and 30 are provided. One connecting roll 60 is formed between the lowermost ends of the interlocking bars 57 formed in the first, second and third directions I, II, and III so as to rotate in the first, second and third directions I, The conveyor belt 12 is formed so as to be close to the rail frame 15 at both the left and right ends so that the interlocking bar 57 formed in a pair with a predetermined distance from the conveyor belt 15, (12). The switching belt 61 wound around the outer circumferential surface of the connection roll 60 which is embedded deeply catches and lifts the bottom surface of the seedlings plate 5 which is moved on the conveyor belt 12 so that it can be towed.

The important point of the present invention is that when the interlocking bar 57 is downwardly moved so that the connecting roll 60 is deeply inserted into the lower ends of the first, second and third conveyor conveying paths 10, 20 and 30, Is brought into close contact with or seated on the upper portion of the conveyor belt 12 placed on the first, second and third conveyor conveying paths 10, 20 and 30. This is important. The adhering roll 59 rotates with the aid of the interlocking action of the conveyor belt 12 of the first, second and third conveyor conveying paths 10, 20 and 30 so as to apply force to the ornamental plate 5 . Further, the operator can perform the function of the stopper and the stopper to prevent the connection roll 60 from being pushed to the lower end of the conveyor belt 12 by the tightening roll 59.
