The seedling bed conveying apparatus and the conveying method according to the present invention is easy to transfer the seedling bed because any one of the plurality of seedling beds arranged to be arranged in the nursery can be picked up or lowered to the pickup unit at random.

In addition, the seedling bed conveying apparatus and the conveying method according to the present invention is provided with a plurality of sensors to detect the presence or absence of the seedling bed, the empty space of the seedling bed, the waiting space of the seedling bed, the deviation of the position due to the sliding during transportation of the seedling bed By notifying the user, the transfer of the seedling bed can be managed efficiently.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a seedling bed conveying apparatus according to the present invention. Referring to the drawings, the seedling bed conveying apparatus according to the present invention is a transfer rail (2) disposed around the seedling bed (1), the pickup unit 10 for transporting the seedling bed while moving along the conveying rail (2) And, the pick-up unit 10 includes a sensor unit for sensing the seedling bed to be transported.

The seedling seedling bed 1 is arrange | positioned in plurality in the seedling seedling chamber, and the place for work of seedling, feeding, shipment, etc. is provided in the outer side of the last seedling seedling bed. In addition, a swing trailer 3 is provided below the seedling seedling beds 1 arranged adjacent to each other so as to provide a small working space between seedling beds. Swing trailer (3) consists of two rollers placed horizontally can move the seedling bed (1) little by little to the left and right. The conveyance rail 2 is arrange | positioned around the seedling bed 1 so that the pick-up unit 10 may move.

The pick-up unit 10 randomly picks up any one of the plurality of seedling beds 1 aligned and transports it to the work space (position). To this end, the pickup unit 10 includes a main body 12, a carrier 14 provided to move up and down on the main body 12, a hook 16 provided on the carrier 14, and a driving member 18. .

Referring to FIG. 2, the pickup unit 10 includes a driving member 18 for moving the pickup unit 10 along the transfer rail 2 and a driving motor 15 for lifting the carrier 14 up and down. do. The drive motor 15 is a winding-type motor connected to four corners of the carrier 14 and the wire 17. The hook 16 is provided at both ends of the carrier 14 and has a solenoid valve controlled by the control unit 5. The hook 16 connected to the solenoid valve and the linker is rotated rearward when descending to pick up the seedling bed, and is fixed in the vertical direction when the seedling bed is lifted up or moved. Unexplained reference numeral 13 is a limit sensor for defining the top dead center and the bottom dead center of the carrier 14.

In addition, the pickup unit 10 is provided with a sensor unit 20 to detect the seedling bed (1) for picking up. The sensor unit 20 includes first, second, third, and fourth sensor parts 21, 23, 25, and 27.

Referring to FIG. 3, the first sensor unit 21 is provided in a pair below the front and rear frame with respect to the moving direction of the pickup unit 10 to recognize the width of the seedling bed 1 (width sensor unit). The width of the seedling bed refers to the front and rear ends of the seedling bed (1) flowing into the pickup unit (10).

The second sensor unit 23 is provided in a pair in the lower side of the front and rear frame of the pickup unit 10 in the same manner as the first sensor unit 21, specifically, provided on the outer side adjacent to the first sensor unit 21. Sensing the space to put the seedling bed (1) (space sensor unit). That is, the first sensor unit 21 is relatively provided on the inside to recognize the seedling bed to be picked up, the second sensor unit 22 is provided on the relatively outside, for example, the space to put down the picked seedling bed Judge whether or not. In order to recognize the correct width and space, a guide wheel 22 for guiding the seedling bed 1 is provided in front of the second sensor unit 23. The guide wheel 22 is a roller which is rotatable in a horizontal direction and is provided in a pair of left and right, and corrects the misplaced position while the seedling bed 1 enters therebetween.

As shown in FIG. 4, the third sensor unit 25 recognizes the center (center) of the seedling bed 1 provided and picked on the center side of the pickup unit 10 (central sensor unit). As described above, each seedling bed 1 has a swing trailer 3 on the lower side so that an operator can move between the seedling beds 1 arranged adjacent to each other. Accordingly, since the center of the seedling bed 1 does not always coincide with the center of the swing trailer 3, the pickup unit 10 uses the third sensor unit 25 to raise the seedling bed 1 and the swing trailer 3. ) To match the center of the

The fourth sensor unit 27 is provided at the center of the frame lower side of the pickup unit 10 (upper side of the third sensor unit 25) to reduce the moving speed of the pickup unit 10 (deceleration sensor unit). The pick-up unit 10 has a different speed when traveling for quickness of work and when picking the seedling bed 1. In addition, such a speed difference may disturb the center of the seedling bed 1 by sliding when picking and transporting the seedling bed 1. Therefore, when the pickup unit 10 approaches the picking or laying seedling bed position set using the fourth sensor unit 27, the seedling bed 1 may be stably transported by reducing the feed speed. In this embodiment, the fourth sensor unit 27 starts to decelerate when the 'T' shaped end of the swing trailer 3 is detected, and when the center of the swing trailer 3 is sensed by the third sensor unit 25. Stop. On the other hand, the center of the pickup unit 10, for example, the counter 28 is provided on the upper side of the third, fourth sensor unit (25, 27), seedling bed (1) passing through the pickup unit (10) Counter to quickly move the pickup unit 10 to the position of the target seedling bed (1).

Then, the operation of the seedling bed transport apparatus having the configuration as described above will be described with reference to FIG.

When the user arbitrarily selects the number of seedling beds to be picked up by the control unit 5, the pickup unit 10 moves to check the seedling bed 1 with the counter 28.

When approaching the seedling bed 1 to be picked up, the pickup unit 10 slows down the moving speed by sensing the fourth sensor part 27, and picks up the center and the seedling bed through the third sensor part 25. Match the center of the unit 10.

If, as shown in (a) of FIG. 5, the first sensor unit 21 detects that there is a seedling bed at the position to be picked up, the pickup unit 10 picks up the corresponding seedling bed 1 and moves to a working position. Let's go. When the first sensor unit 21 detects that there is no seedling bed 1 in the position to pick up, the control unit 5 notifies the worker to a notification member (not shown), such as an alarm bell, an alarm.

On the other hand, in order to put down the picking seedling bed (1), first the pickup unit 10 is moved to the corresponding position and then check whether the seedling bed () in the corresponding position through the first sensor unit 21 and at the same time Check whether the space of the seedling bed (1) is secured in the corresponding position through the 2 sensor unit (23).

When the width and the space where the seedling seedling bed 1 can be put down as shown in FIG. 5 (b) are confirmed, the pickup unit 10 puts down the seedling seedling bed 1 being picked up. If the width and / or space of the seedling bed 1 is not secured as shown in (c) or (d) of FIG. 5, as described above, a notification member (not shown) such as an alarm bell or an alarm may be used. Notify the worker. (c) and (d) shows that when the nursery bed is pushed from one side of the aligned seedling bed, the worker moves the position of the seedling bed 1 slightly to the swing trailer 2 for the arbitrary work. The position is brought to a steady state (the center of the seedling bed coincides with the center of the swing trailer).

At the ends of the plurality of seedling beds 1 arranged in alignment, a limit (not shown) for restricting the movement of the pickup unit 10 is installed, and the pickup unit 10 can appropriately designate a standby position according to the operator's setting. .

As such, the present invention has the effect of maximizing the convenience of the work by minimizing the inconvenience of the operator by efficiently managing the transfer of the seedling bed 1 by using a plurality of sensors.
