Description

Technical Field

[0001] This invention relates to a seedling box stacking and removal device, and more specifically, to a seedling box stacking and removal device that, after the seedling boxes delivered by the seeder after the soil and seeds have been sown, are automatically stacked in sequence, and then pushed to the discharge device side by a pushing device at predetermined intervals, the seedling boxes are stably transported without shaking or scattering, thereby improving work efficiency. Background Technology

[0002] like Figure 1 As shown in Figure 4, the existing seedling box stacking and removal device transports the seedling boxes B that have been sown to the stacking section 20 via the conveying device 10. The seedling boxes B transported to the stacking section 20 are stacked according to a preset number. After stacking, the pushing device 30 pushes the seedling boxes B to the side and discharges them to the discharge device 40.

[0003] The conveying device 10 is used to transport the seedling box B after sowing. The conveying device 10 includes a conveying roller 11, and the seedling box B is transported by the rotation of the conveying roller 11 or by a conveyor.

[0004] The stacking section 20 is used to stack the seedling boxes B transported by the conveying device 10 in multiple layers. The stacking section 20 can be arranged at the end of the conveying device 10 or at the middle position of the conveying device 10.

[0005] The stacking unit 20 may include a detection mechanism for detecting the seedling boxes B that are being transported. When the seedling boxes B arrive at the position where they need to be stacked, the mechanism detects them and sends a detection signal to the control unit.

[0006] After the seedling box B reaches the predetermined position for stacking and sends a detection signal to the control unit, according to the instruction of the control unit, the lifting mechanism located below the stacking section 20 pushes the seedling box B from below upward, so that the seedling box B is stacked on the upper part of the support plate 21.

[0007] The seedling box B is usually rectangular in shape. In order to provide stable support for the seedling box B, the mounting plate 21 is set at the positions corresponding to the four corners of the rectangle.

[0008] Furthermore, when the seedling boxes B are stacked on top of the mounting plate 21, in order to stack the next seedling box B, another seedling box B is continuously transported by the conveying device 10 to the position where it needs to be stacked. Following the same order as the previously stacked seedling boxes B, it is moved upward by the lifting mechanism located below the stacking section 20. During the upward movement, it pushes the seedling box B supported by the mounting plate 21 and rises together. Then it is positioned on the upper layer of the mounting plate 21, thereby forming a structure in which the seedling boxes B are stacked sequentially.

[0009] The existing lifting mechanism, after raising and lowering the seedling box B and stacking it in the stacking position, will descend back to its original position. This is not only to return to the original lower position for raising and lowering the new seedling box B, but also because when the lifting mechanism rises to the position for stacking the seedling box B, the lifting plate 22 of the lifting mechanism will be in a position higher than the bottom plate 32 of the pushing device and the mounting plate 21 of the stacking device. Therefore, if the lifting mechanism does not return to its original position and stays in this state, it will hinder the reciprocating movement of the pushing device 30.

[0010] For example, regarding the lifting mechanism, reference can be made to Korean Patent No. 10-1868578, which is held by the applicant. Figure 1 As shown in Figure 4, it includes: a lifting plate 22 for supporting the seedling box B; a piston rod 24 attached to the lower surface of the lifting plate 22 for raising the lifting plate 22; a cylinder 23 for driving the piston rod 24; and a switch 25 for detecting and limiting the movement of the piston rod 24.

[0011] When the number of seedling boxes B stacked reaches a preset number, the pushing device 30 pushes the stacked seedling boxes B from the side, causing them to be discharged to the discharge device 40.

[0012] The pushing device 30 includes: a cylinder 34; a piston rod 35 that reciprocates; a pushing plate 33 mounted on the piston rod 35 for pushing the seedling box; and a base plate 32 attached below the pushing plate 33 for supporting the lower end of the seedling box.

[0013] However, in the existing device, when the action of pushing the seedling box B to the side discharge device 40 is performed, the seedling box B stacked in the stacking part 20 is only supported by the placement plate 21 located near the four corners of the seedling box, and the bottom plate 32 of the pushing device 30 is located below the placement plate 21.

[0014] In this state, when the pusher plate 33 of the pusher device 30 pushes the side of the seedling box B, after moving a distance corresponding to the width of the placement plate 21, the side of the seedling box B will fall from the placement plate 21 onto the bottom plate 32 of the pusher device, and then be pushed again by the pusher plate 33. At the moment when one side of the seedling box B falls onto the bottom plate 32 of the pusher device, due to the impact of the fall, the seedling box B is prone to an unstable arrangement, and there is a risk that it will be discharged to the discharge device 40 in this unstable state. That is to say, at the moment when the two sides of the seedling box fall onto the bottom plate 32, the seedling box will tilt, thus moving in a tilted and unstable state (see...). Figure 4b ).

[0015] Furthermore, while the seedling box B is being pushed further with one side tilted, as... Figure 4c , 4d As shown, the seedling box B will rise in the direction of movement with reference to the placement plate 21 on the side of the discharge device 40, and then eventually fall to the discharge device 40, thus there is a problem that the seedling box B ends its movement in a scattered state.

[0016] Furthermore, in order to place the seedling box on the placement plate, when the lifting plate is raised to its maximum position, the lifting plate will be above the placement plate, and therefore also above the base plate of the pushing device.

[0017] The reason why the bottom plate 32 of the pushing device 30 is located below the placement plate 21 is that the stacked seedling boxes B are only supported by the placement plate 21 near its four corners. Therefore, in order to push the seedling boxes B stably, it is necessary to apply a pushing force to its sides while supporting the seedling boxes B from below. Based on this, the bottom plate 32 is formed in the pushing device 30, and the bottom plate 32 is located below the placement plate 21.

[0018] In order to place the seedling box B on the placement plate 21 by raising the lifting plate 22, the placement plate 21 will be lifted and rotated by the seedling box B raised by the lifting plate 22, and then support the seedling box B from below during the process of returning to the original state.

[0019] Therefore, when the existing lifting plate 22 rises to its maximum position, it will be above the placement plate 21. Thus, in order for the pushing device 30 to perform the action of pushing the seedling box B, the lifting plate 22 needs to descend again and return to its original position. If a device malfunction occurs, such as the lifting plate 22 failing to return to its original position after supplying the seedling box B, and the pushing device 30 performs the action of pushing the seedling box B under these circumstances, problems such as collisions between the pushing device 30 and the lifting plate 22 may occur.

[0020] Furthermore, after the lifting plate 22 descends back to its original position, if a malfunction occurs such as the lifting plate 22 rising again during the pushing action of the pushing device 30 to push the seedling box B, the pushing device 30 and the lifting plate 22 may collide.

[0023] (Patent Document 1) Korean Patent No. 10-1868578 Summary of the Invention

[0024] [Technical Issues]

[0025] The purpose of this invention is to provide a seedling box stacking and removal device, wherein, after the seedling boxes delivered by the seeder after the soil seed sowing is completed, are automatically stacked in sequence, and during the operation of pushing the seedling boxes to the discharge device side by the pushing device at predetermined intervals, the seedling boxes can be stably transported without shaking or scattering.

[0026] [Technical Solution]

[0027] To achieve the above objectives, the present invention provides a seedling box stacking and removal device, which receives seedling boxes that have been sown in the soil via a conveying device and stacks them, while simultaneously removing the stacked seedling boxes in a specified quantity. The seedling box stacking and removal device includes:

[0028] A stacking device, connected to the conveying device, is used to stack the conveyed seedling boxes upwards;

[0029] Multiple placement plates are provided on the upper part of the stacking device to support the seedling boxes that are loaded and stacked upwards;

[0030] A pushing device is provided on one side of the stacking device for pushing the seedling box supported by the mounting plate to the discharge device side on the opposite side.

[0031] A discharge device, formed parallel and orthogonal to the stacking device, is used to receive and remove seedling boxes pushed by the pushing device, and is driven at a speed set to match the operating conditions of the pushing device; and

[0032] The control unit is used to control the operation of the conveying device, the stacking device, the pushing device, and the discharging device according to set conditions.

[0033] The stacking device of the present invention includes:

[0034] Framework; and

[0035] A seedling box guide is formed on the bottom surface of the frame to guide the seedling boxes that are transported into the inside of the frame to the position where they should be stacked.

[0036] Furthermore, a lifting component is provided at the lower part of the stacking device to push the seedling boxes, which are transported to the stacking position by the seedling box guide, upward, so that the seedling boxes are stacked on the placement plate provided on the frame.

[0037] The lifting component of the present invention includes: a lifting cylinder arranged in the lower part of the frame of the stacking device; and a lifting plate coupled to a piston rod that is driven by the lifting cylinder to move up and down reciprocally.

[0038] In addition, it may further include: a sliding plate disposed on the upper part of the lifting plate for supporting the seedling box and supporting the seedling box when it is transported to the discharge device so that the seedling box can slide stably.

[0039] The sliding plate of the present invention has grooves formed along the moving direction of the seedling box in order to make the seedling box move stably.

[0040] The sliding plate of the present invention is made of a material with a low coefficient of friction in order to enable the seedling box to move stably.

[0041] When the lifting component rises to its highest position, the sliding plate is located below the lowest position of the pushing device.

[0042] Furthermore, the placement plate of the present invention is mounted on the upper part of the seedling box guide via a hinge portion, and a spring device is provided in the hinge portion, so that the rotation of the placement plate is performed in an elastic manner.

[0043] Furthermore, the pushing device of the present invention includes: a cylinder disposed on one side of the frame of the stacking device and driven by a pneumatic or electric motor; a piston rod mounted on the cylinder for reciprocating motion; a pushing plate disposed on the piston rod for pushing the seedling box; and a switch for detecting the movement of the piston rod.

[0044] Furthermore, the discharge device of the present invention includes a conveying mechanism that operates in accordance with the operating speed of the cylinder of the pushing device. The conveying mechanism is used to remove the seedling box pushed by the pushing plate to one side and is only linked with the cylinder when it is running, so that the seedling boxes can be conveyed sequentially.

[0045] Furthermore, the lifting plate of the lifting component of the present invention can be raised and lowered to a position for placing the seedling box on the placement plate by the operation of a lifting cylinder arranged at the lower part of the frame of the stacking device and a piston rod that is driven by the lifting cylinder to move up and down reciprocally; and after the seedling boxes are stacked on the placement plate in a predetermined number, the lifting plate moves to a height position at the same horizontal line as the upper part of the placement plate and the conveying mechanism of the discharge device and is positioned.

[0046] According to the present invention, when the seedling box begins to move toward the discharge device side under the pushing action of the pusher plate, the lifting plate of the lifting member descends back to its original position, thereby enabling the stacking of subsequent seedling boxes to be performed.

[0047] [Beneficial Effects]

[0048] According to the seedling box stacking and removal device of the present invention, during the process of pushing the seedling box to the discharge device, the seedling box is stably supported and transported by the sliding plate of the lifting component, thereby achieving stable transport of the seedling box.

[0049] Furthermore, when the lifting component rises to its highest position, the lowest position of the pushing device is located above the lifting plate or sliding plate of the lifting component. Therefore, even if the lifting component and the pushing device malfunction, they will not collide with each other, thus providing the advantage of easy control over the lifting component and the pushing device.

[0050] Furthermore, after the stacked seedling boxes are pushed to the discharge device by the pushing device, the lifting component can be lowered to its original position below the frame before the pushing device returns to its original position, thus completing the preparation for the next stacking operation, which has the advantage of improving the operation speed.

[0065] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0066] This invention relates to a seedling box stacking and removal device, which receives seedling boxes B that have been sown in the soil via a conveying device 100 and stacks them, while simultaneously removing a specified number of stacked seedling boxes B. The seedling box stacking and removal device includes:

[0067] A stacking device 200 is connected to the conveying device 100 for stacking the conveyed seedling boxes B upwards.

[0068] Multiple placement plates 210 are disposed on the upper part of the stacking device 200 to support the seedling boxes B that are loaded and stacked upwards;

[0069] A pushing device 300 is disposed on one side of the stacking device 200 for pushing the seedling box B supported by the placement plate 210 to the discharge device 400 side on the opposite side.

[0070] A discharge device 400, formed parallel and orthogonal to the stacking device 200, is used to receive and remove the seedling box B pushed by the pushing device 300, and is driven at a speed set to match the operating conditions of the pushing device 300; and

[0071] The control unit 500 is used to control the operation of the conveying device 100, the stacking device 200, the pushing device 300 and the discharging device 400 according to set conditions;

[0072] The stacking device 200 includes:

[0073] Frame 201; and

[0074] A seedling box guide 202 is formed on the bottom surface of the frame 201 to guide the seedling boxes B that are transported into the inside of the frame 201 to the position where they should be stacked.

[0075] Furthermore, a lifting component is provided at the lower part of the stacking device 200 to push the seedling box B, which is transported to the stacking position by the seedling box guide 202, upward, so that the seedling box B is stacked on the placement plate 210 provided on the frame 201.

[0076] The lifting component includes: a lifting cylinder 221, arranged at the lower part of the frame of the stacking device 200; a lifting plate 220, coupled to a piston rod 222 that reciprocates up and down driven by the lifting cylinder 221; and a sliding plate 230, disposed at the upper part of the lifting plate 220, for supporting the seedling box and supporting the seedling box when it is transported to the discharge device so that the seedling box can slide stably.

[0077] Furthermore, the placement plate 210 of the present invention is mounted on the upper part of the seedling box guide part 202 via a hinge part 211, and a spring device 212 is provided on the hinge part 211, so that the rotation of the placement plate 210 is performed in an elastic manner.

[0078] Furthermore, the pushing device 300 of the present invention includes: a cylinder 301 disposed on one side of the frame of the stacking device 200 and driven by a pneumatic or electric motor; a piston rod 302 mounted on the cylinder 301 for reciprocating motion; a pushing plate 330 disposed on the piston rod 302 for pushing the seedling box B; and a switch 304 for detecting the movement of the piston rod 302.

[0079] Furthermore, the discharge device 400 of the present invention is provided with a conveying mechanism 410 that operates in accordance with the operating speed of the cylinder 301 of the pushing device 300. The conveying mechanism 410 is used to remove the seedling box B pushed by the pushing plate 330 to one side, and is only linked with the cylinder 301 when it is running, so that the seedling box B can be conveyed sequentially.

[0080] Furthermore, the lifting plate 220 of the lifting component of the present invention can be raised or lowered to a position for placing the seedling box B on the placement plate 210 by the operation of the lifting cylinder 221 arranged in the lower part of the frame of the stacking device and the piston rod 222 that is driven by the lifting cylinder 221 to move up and down.

[0081] Furthermore, in this invention, the upper part of the lifting plate 220 may be combined with a sliding plate 230 for smoothly transporting the seedling box B, and a groove 231 may be formed on the sliding plate 230 along the moving direction of the seedling box B.

[0082] Furthermore, after the seedling boxes B are stacked on the placement plate 210 in a predetermined number, the lifting plate 220 of the lifting component of the present invention will move and position itself at the same height as the upper part of the placement plate 210 and the conveying mechanism of the discharge device, so that the seedling boxes B can be supported from below during the process of the pushing device 300 pushing the seedling boxes B to the discharge device 400, so that the seedling boxes B can be transported smoothly.

[0083] The stacking and unloading operations of the seedling boxes according to the present invention will now be described. In particular, reference will be made to... Figures 10a to 10d The work procedures performed using this invention will be described.

[0084] Seedling boxes B, which undergo sowing using a known general sowing device, are conveyed to stacking device 200 via conveying device 100. The seedling boxes B conveyed to stacking device 200 are stacked in a pre-set quantity. After stacking, they are pushed laterally by pushing device 300 and discharged to discharge device 400 (see...). Figure 5 , Figure 6 ).

[0085] The conveying device 100 is used to convey seedling boxes that have been sown. It includes a conveying roller 101, and the seedling boxes are conveyed by the rotation of the conveying roller 101 or by a conveyor.

[0086] The stacking device 200 is used to stack the seedling boxes B transported by the conveying device 100 in multiple layers. The stacking device 200 can be arranged at the end of the conveying device 100 or at the middle position of the conveying device 100.

[0087] The stacking device 200 may include a detection mechanism for detecting the seedling box B being transported. When the seedling box B reaches the position where it needs to be stacked, a switch of the detection mechanism detects that the seedling box B has reached a preset position and sends a detection signal to the control unit 500.

[0088] When the seedling box B reaches the upper surface of the lifting plate or the upper surface of the sliding plate 230 of the lifting member formed in the stacking device 200 for stacking and is detected by the detection mechanism, after sending a detection signal to the control unit 500, the lifting member located below the stacking device 200 pushes the seedling box B from below upward according to the instruction of the control unit 500, so that the seedling box B is stacked on the upper part of the support plate 210, which is like a support platform; wherein, as the lifting cylinder 221 operates, the lifting plate 220 connected to the piston rod 222 rises to the upper part of the stacking device 200, and the seedling box B located on the upper surface of the lifting plate 220 or the sliding plate 230 rises while the support plate 210 rotates, and then is placed and positioned on the support plate 210 that has returned to its original position when the piston rod 222 descends back to its original position.

[0089] The seedling box B is typically rectangular in shape. To provide stable support for the seedling box B, the mounting plate 210 is positioned near the four corners of the rectangle.

[0090] Furthermore, when the seedling boxes B are stacked on the upper part of the mounting plate 210, in order to stack the next seedling box B, another seedling box B is continuously transported by the conveying device 100 to the position where it needs to be stacked. Following the same order as the previously stacked seedling boxes B, the lifting member located below the stacking device 200 moves upward. During the upward movement, it pushes the seedling box B supported by the mounting plate 210 and rises together. Then it is positioned on the upper layer of the mounting plate 210, so that the seedling boxes B can be stacked in sequence.

[0091] Subsequently, after the seedling boxes B are stacked in the preset quantity, the lifting component will not descend back to the lower part of the stacking device as its original position, but will move to a position where the lifting plate 220 or the sliding plate 230 is at the same height as the upper part of the placement plate 210.

[0092] After the stacking process of the seedling box B is completed and the lifting plate 220 or sliding plate 230 of the lifting component is positioned at a preset height, the pushing device 300 pushes the stacked seedling box B so that it is discharged to the discharge device 400.

[0093] The pushing device 300 includes: a cylinder 301; a piston rod 302 that reciprocates; a pushing plate 330 mounted on the piston rod 302 for pushing the seedling box B; and a switch 304 for controlling the moving distance of the piston rod 302, etc.

[0094] The seedling box B is placed on the mounting plate 210, and the mounting plate 210 is at the same height as the lifting plate 220 or the sliding plate 230. Therefore, the stacked seedling box B can be discharged to the discharge device 400 in a stable state without shaking simply by pushing the push plate 330 of the pushing device 300 from the side.

[0095] After the switch 304 on the pushing device 300 detects that the piston rod 302 has moved a preset distance, the piston rod 302 returns to its original position and enters a state of waiting for the next operation.

[0096] The discharge device 400 is provided with a conveying mechanism 410 that operates in accordance with the operating speed of the cylinder 301 of the pushing device. The conveying mechanism 410 is used to take out the seedling box B pushed by the pushing plate 330 to one side, and it only works in conjunction with the cylinder when it is running, so that the seedling box B is conveyed sequentially.

[0097] The pusher plate 330 of the pusher device 300 is positioned higher than the mounting plate 210 and the lifting plate 220 or the sliding plate 230, thereby structurally preventing the pusher plate 330 from interfering with the lifting component. This fundamentally prevents the pusher device from colliding with the lifting component due to malfunction, avoiding the problem of collision between the pusher device and the lifting component that occurs in existing stacking devices.

[0098] On the other hand, the sliding plate 230 has a groove 231 formed along the moving direction of the seedling box, thereby enabling the seedling box to move smoothly and stably. Furthermore, to ensure stable movement of the seedling box B, the sliding plate 230 can be made of materials with low coefficients of friction, such as metal, zirconia ceramic, or polytetrafluoroethylene.

[0099] In another embodiment of the present invention, the lifting plate 220 can also perform the functions of a lifting plate and a sliding plate at the same time, that is, the lifting plate 220 and the sliding plate can be integrally formed.

[0100] This invention is not limited to the specific preferred embodiments described above. Various modifications can be made by those skilled in the art without departing from the spirit of the claims, and all such modifications should fall within the scope of the claims.
