Description

Seeding culture box stacking device

The present invention relates to a laminating apparatus of a seedling box that can be extracted from the conveyor by stacking a certain number of seedling boxes run by the conveyor, and more specifically, in a position in which the seedling boxes are run at a constant speed by the conveyor to be stacked, sequentially In the seedling box stacking device for stacking the plurality of seedling box release holding pieces, and then to be extracted from the conveyor so that the seedling box release holding pieces formed on the four sides of the position where the conveyor seedling box is to be stacked. While the seedling box lifting and holding pieces in front of the seedling box's driving direction are driven to the conveyor, the seedling box stops running, and then the seedling box stopped by the operation of the lifting plate on the bottom of the conveyor can be placed on the seedling box lifting and holding pieces. Driven by conveyor Maintain the left and right parts of the unstrained seedling box in the forward direction so that they are aligned and stacked on all the mounting jaws of the seedling box release holders, so that the operation of the machine is caused by the trouble of the stacking of the seedling boxes in the stacking position. The present invention relates to a laminating apparatus for a seedling box capable of preventing a decrease in productivity such as stopping the productivity.

In general, seedling boxes are used to cultivate seeds and fertilize seeds correctly to cultivate crops such as rice seed and the like, and to facilitate movement.

For the growth of seeds in the seedling box above, the seeds are treated with chemicals, the soil is placed in a seedling box at a certain height, and the seeds are planted in the soil so that germination is formed.

In addition, the seed of the seedling box germinates by supplying a certain amount of water, and when the root of the seed grows, it is transplanted using a rice transplanter.

In addition, the rice transplanter is to be supplied with a seedling box continuously, in the process of working one by one worker is supplied by hand from the supply side to work.

However, when working in this way, one worker must always be in the supply position of the seedling box, so there is a disadvantage that is not suitable for the rural reality lacking work.

In addition, the supply of the seedling box is generally using a conveying conveyor, a known agricultural loading box conveying conveyor for transporting to a certain position to drive the drive pulley by the driving force of the drive source and to drive the driven pulley and the driven pulley connected to the belt interlocked Conveyors are known that transfer loads from a loading and shipping position to a fixed position by allowing a load to be loaded on the conveyor and traveling.

In addition, in the case of the driving means of the conveyor, chains or belts are adopted depending on the conveyed load, and in general, chains are used when the load of the load is large or the load takes a lot of travel. Or the belt is adopted when there is little load on the road.

In addition, in the case of the chain is adopted a lot of cases that require the precision, such as running speed and timing, there is a disadvantage that the equipment cost is relatively expensive, and in the case of the belt, there is a problem that the deformation is easier and less durable than the chain, It is adopted because of the relatively low price and the low cost of equipment.

In addition, there is a laminating apparatus in which a seedling box is driven on the conveyor so that a predetermined amount is stacked. For example, in Japanese Patent Application Laid-Open No. 2010-195562, the plurality of shafts 15 are equally spaced on the two frames 13 and 13. Rubber rollers 16 are mounted on the shafts 15, and the rubber rollers 16 are driven to the rubber rollers 16 in a rotational motion by a driving means connected to a driving source, so that the seedling box 19 is formed. Move to the position to be stacked.

In addition, at the position where the seedling box 19 is to be stacked, the shaft 27 is driven by the sprocket 43 and the chain 45 connected to the motor 35 and connected to the chain 45 to drive the shaft 27. An arm 30 is fixed to the shaft 27, and rollers 31 are formed on the arm 30 so as to be rotatable, and the seedlings are driven on the rubber roller 16 by the eccentric driving of the rollers 31. The bottom of the box 19 is pushed up so that the seedling box 19 moves upward.

The seedling raising box 19 raised from the bottom is stacked on the holding pieces 57 having the inclined portion 57b formed elastically by the torsion spring 59 formed on the plate 25.

The seedling box 19 laminated | stacked on these holding pieces 57 can set the lamination number of the seedling box 19 controlled and laminated by the limit switch 33 formed in the upper part of the plate 32. As shown in FIG. Extracting the seedlings 19 stacked in a predetermined number of holding pieces 57 as described above is transferred to a rice transplanter.

As described above, the seedling boxes 19 stacked on the holding pieces 57 are extracted, and there is a inconvenience in that a lot of effort is required to move the rice transplanter and the like.

In order to alleviate the above inconvenience, there are structures that push the stacked seedling boxes 19 sideways from the apparatus using a cylinder, but equipment costs such as installing a separate pushing member and a cylinder separately are expensive. there is a problem.

In addition, in Japanese Patent Application Laid-Open No. 2007-296627, a cylinder is used as a structure for pushing up the seedling box, but this also has a problem in that equipment costs such as separately installing a driving member and a cylinder to push out separately are expensive.

In addition, in the Republic of Korea No. 10-2018-0002040 proposed by the present applicant, the seedling box is controlled and placed on the step of the lifting plate stably without trouble with the lifting plate at the position where the seedling box is run and stacked at a constant speed by the conveyor. The hinge driving of the seedling box release maintenance piece, which allows a certain number of seedling boxes to be placed by the lifting plate, is formed above the direction in which the seedling box enters, so that the opening operation and also the seedling box are placed on the seedling boxes. Hinge driving such as narrowing operation to be made is made on the upper side of the stacking column.

As above, the lifting plate can be raised and lowered stably, and also the soil of the seedling box is prevented from flowing in the hinge driving of the release of the seedling box release and maintenance, so that the raising and lifting of the seedling box can be performed smoothly. Since the central side of the seedling box that is driven by the step of the steel plate is controlled, if the seedling box is not aligned in the forward direction and the soil of the seedling box is separated from the plate of the flat plate, the four corners of the seedling box are left and right on the plate by the soil. The defect that the operation of the machine is stopped due to trouble such as entanglement of seedling boxes with each other and not being stacked on the seedling box unloading retaining parts of the four sides at the position to be stacked by lifting of the lifting plate There is a problem that the seedling box bounces off and causes a safety accident.

The drive linkage sensor 56-2 detects and stops the operation of the step motor 51 and also the drive motor 3 of the conveyor 1.

In addition, the lifting plate 50 is formed with an inclined surface 57 which is bent downward on the side in which the seedling box 10 enters, the seedling box 10 is guided along the inclined surface 57, the lifting plate 50 It is supposed to be able to enter. The seedling box 10 is driven by the conveyor 1 at a constant speed by the inclined surface 57 and stopped at the stop 20 by the stoppers 0 of the seedling box release holding piece 31. The seedling box 10 may be stably placed on the lifting plate 50 without trouble with the lifting plate 50.

As shown in FIG. 1, when the seedling box 10 enters the position 20 to be stacked, the speed of the seedling box 10 that is elastically entered at a constant speed of the elastic piece 6 formed on the conveyor 1. Can be reduced.

And, as shown in Fig. 1, Fig. 2a, b, 3a, b, 4a, b the seedling box 10 is reduced the speed of the seedling box all around the position 20 to be stacked on the conveyor (1) Control in both front parts of the seedling box 10 which is driven by the stopper 70 extended to the front of the seedling box unloading retaining pieces 31 in the running direction of the seedling box unloading retaining pieces 31. The seedling box 10 is stopped.

Subsequently, as shown in FIGS. 5A and 5B, the elevating plate 50 is raised by driving the driving disks 56 of the reducer 52 and driving of the elevating link 53, and lifting the seedling box 10 to raise the seedling box ( 10) is placed on the mounting jaw 38 along the lower inclined surface 39 of the seedling box release holding pieces 31 of the stacking column 30.

As shown in FIG. 4A, when the seedling box 10 is placed on the seedling box release holding piece 31 of the stacking pillar 30, the lifting link 53 is driven by driving the driving disc 56 of the reducer 52. It descends and waits to raise the next seedling box 10.

2A and 4B, when the seedling boxes 10 are stacked in a set number by the repeated driving of the elevating plate 50, the release stack 44 of the stacking control box 40 is stacked. The seedling box release release piece which was supporting the bottom of the seedling box 10 as the pushing slope 36 was pushed up from the corner jaw 37 of the seedling box release release piece 31 of the holding pillar 30 ( 31 is pushed out of the stacking column 30 so that the entire seedling box 10 is placed on the belts 4 of the conveyor 1.

As a result, the seedling boxes 10 in the stacked state as shown in FIGS. 2B and 3B are mounted on the belts 4 of the conveyor 1 and travel with the control piece 61 provided at the center of the conveyor 1. As it pushes out, the control piece 61 causes the stacking control box 40 connected to the linkage 60 to be returned to its original position.

The linkage device 60 includes a control link 63 formed on the shaft 62 of the control piece 61 rotatably formed on the conveyor 1 as shown in Figs. 1 and 2A, B, and the seedlings. The drive link 65 formed elastically by the spring 67 around the link shaft 64 at the position at which the box 10 is to be stacked is connected to each other by a connecting rod 66.

Thus, while the stacked seedling boxes 10 are extracted by the conveyor 1 at the position 20 at which the stacked seedling boxes 10 are stacked, the holding jaw 47 of the stacking control box 40 is connected to the link shaft of the drive link 65. Raised on the opposite side of the (64) to keep the state away from the conveyor (1).

The driving link 65 connected to the control piece 61 and the connecting rod 66 by the striking of the seedling boxes 10 stacked in the above state by the hitting of the control piece 61 is centered on the link shaft 64. By moving counterclockwise, the stack control box 40 returns to the original frame 5 in an instant. And this stacking control box 40 can receive the seedling box 10 to be stacked next.

Next, a description of the working example of the present invention is as follows.

When the power supply of the present invention is turned on, the conveyor 1 drives the belt 4 from the right side to the left side by driving the driving motor 3 in FIGS. 1, 2A, 3B and 3A, 3B, and the seeding is completed. The seedling boxes 10 are fed onto the belt 4 of the conveyor 1 by automatic or manual.

In FIG. 1, when the seedling box 10 on the belt 4 reaches the position 20 to be gradually stacked, the traveling speed is reduced by the elastic piece 6 that is elastically erected on the conveyor 1. As shown in 3a, among the seedling box release holders 31 on all sides of the position 20 at which the conveyor 1 is to be stacked, the front seedling box release holders 31 in the traveling direction of the seedling box 10 are shown. The seedling box 10 is stopped by controlling from both front portions of the seedling box 10 that is driven by the stoppers 70 extended to.

The seedling box 10 which runs on both sides of the frame 5 of the conveyor 1 has a portion intersected by the L-shaped stopper 70 of the seedling box release retaining pieces 31 to keep the stop. In addition, by maintaining the sides along with the stop portion by the side portion extending to the transverse portion to maintain the left and right, as well as the front, rear portion of the seedling box 10 in the forward direction. Wherein the forward direction is in the aligned position that can be elevated by the elevating plate 50 in the position 20 in which the seedling box 10 is to be stacked, on the mounting jaws 38 of the seedling box release holding pieces 31. It means that the four corners of the seedling box 10 can be accurately seated.

In addition, in the present invention, the stoppers 70 of the seedling box placing and holding piece 31 are formed in a vertical direction with respect to the plane of the conveyor 1 in a substantially L-shape, so that the soil of the seedling box 10 is a stopper 70. Even if it falls on the field immediately falling down the conveyor 1, the stopper 70 does not have any influence on the control and lamination of the seedling box 10 in the conveyor 1, the position to be stacked (20) The seedling box 10 in Esau can solve the problem of stopping the operation of the conveyor due to the trouble of the warping stack.

As described above, when the seedling box 10 is aligned in the position to be stacked 20, the step motor 51 is operated as shown in Fig. 5a to 5b, the lifting link 53 through the drive disk 56 of the reducer 52. ) Drive upwards, so that the lifting plate 50 is moved to the uppermost stage, at which time, the seedling box 10 on the lifting plate 50 is fixed rod of the stacking column 30 of Fig. 4A The hinge rods 35 are pushed upward by pushing the lower inclined surface 39 of the seedling box release retaining piece 31 of the hinge rod 35 that is stretched to the elasticity 32 and is elastically maintained. To overcome, eventually pushing the hinge rod 35 out of the stacking pillars (30).

Subsequently, as the lifting link 53 connected to the driving disc 56 moves downward by the drive of the reducer 52 of the step motor 51 which continues to rotate, the lifting plate 50 moves to its original position, The seedling box 10 on the steel plate 50 is also moved downward, and as shown in FIG. 4A, the seedling box 10 is mounted on the mounting jaw 38 of the seedling box release holder 31, and at this time, the hinge rod 35. ), The seedling box 10 may be maintained on the mounting jaw 38 of the seedling box release holding piece 31 by the restoring force of the elastic spring (33).

Again, when the lifting plate 50 is horizontal to the conveyor 1, the seedling box 10 to be supplied is placed on the lifting plate 50 as described above, and the lifting plate is driven by the step motor 51. As the 50 rises, the seedling box 10 on the lifting plate 50 pushes the seedling box 10 placed on the seedling box release holding pieces 31 of the laminated holding pillar 30. Raised.

When the seedling box 10 of the seedling box release holding pieces 31 are pushed up, the seedling box release holding pieces 31 are moved back to the original position by the restoring force of the elastic spring 33, Subsequently, as the elevating link 53 moves downward by the driving of the reducer 52 of the stepper motor 51, the lower plate of the plurality of seedling boxes 10 is seeded while the elevating plate 50 moves to its original position. The box unloading retaining pieces 31 are supported (see FIG. 4A).

As described above, the lifting plate 50 can be stacked in the desired seedling box 10 by the repeated stroke to lift the seedling box 10.

The number of stacked seedling boxes 10 can be stacked, the control rods 43 can be selectively traversed to the setting holes 42 in the direction perpendicular to the opposing surfaces 41 of the stacking control box 40, If you want to stack a lot of seedling boxes 10, the control rod 43 is inserted into the upper setting hole 42, on the contrary, if you want to stack a small number of seedling boxes 10 to overlap the lower setting hole ( The number of the seedling boxes 10 to be stacked in the stacking control box 40 may be limited and set by inserting the control rod 43 into 42.

As shown in FIGS. 2A and 4A, when the seedling boxes 10 are stacked in a set number in the stacking control box 40 by the repeated driving of the elevating plate 50, as shown in FIG. 4B, the stacking control box ( As the release bar 44 of the 40 is pushed up from the corner jaw 37 of the seedling box holding piece 31 of the stacking pillar 30 toward the inclined plane 36, the seedling box 10 The seedling box release holding piece 31 which was supporting the bottom is elastically pushed outward of the stacking column 30 so that the seedling box 10 is placed on the belts 4 of the conveyor 1.

At this time, as shown in FIG. 3b, the seedling box release holding pieces 31 are pushed out of the stacking pillar 30 to allow the seedling box 10 of the conveyor 1 to travel.

As a result, the seedling boxes 10 in the stacked state as shown in FIG. 2B are mounted on the belts 4 of the conveyor 1 and travel while being mounted on the belts 4 of the conveyor 1. As the 61 is pushed out, the drive link 65 connected with the control piece 61 and the connecting rod 66 is instantaneously moved by the counterclockwise movement about the link shaft 64. 40 returns to the original frame 5 in its original form. And this stacking control box 40 can receive the seedling box 10 to be stacked next.

In addition, the conveyor 1 is formed with a drive motor 3 for driving the belt 4 of the conveyor and a step motor 51 for driving the lifting plate 50, and the drive motor 3 is a conveyor ( The seedling box 10 of 1) travels to the position 20 to be stacked, and the step motor 51 stacks the seedling box 10 arriving at the position 20 to be stacked.

In the present invention, the control box 100 stands on the frame 5 of the conveyor 1 and is fixed to the position 20 to be stacked on the conveyor 1.

This allows the operator to confirm that the seedling box 10 is stacked at the position 20 at which the conveyor is to be stacked, while the emergency switch of the control box 100 is immediately operated in an emergency such as unreasonable driving and stacking of the seedling box 10. Since the operation can be performed smoothly, safety accidents can be prevented.
