Description

Technical Field

[0001] The present invention relates to an automatic stacking machine for rice seedling trays, belonging to the technical field of agricultural equipment. Background Art

[0002] As shown in the traditional automatic stacking machine for seedling trays, such as the Chinese utility model patent "Authorized Publication Number: CN221419711U; Authorization Publication Date: July 26, 2024; Title: An Automatic Stacking Machine for Seedling Boxes", a first conveying device is used to send a small seedling tray group into the stacking device. The stacking device first lifts the small seedling tray groups one by one in batches, and then uses the pushing mechanism at the top to push the small seedling tray group at the topmost position forward, stacking multiple small seedling tray groups into a large seedling tray group. Then, a fork conveying device is used to fork multiple large seedling tray groups onto a pallet, and finally, a blanking device is used to send out the pallet with the large seedling tray group to achieve blanking. Although this solution can achieve rapid stacking of seedling trays, there is a situation where the seedling trays are prone to loosen and fall during the transportation process. In addition, sometimes it is necessary to carry out darkening treatment on the seedlings. For the seedling trays stacked by this kind of equipment, workers need to manually wrap them with black film, and there are also defects such as high labor intensity of workers and low production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned technical defects of the traditional seedling tray stacking machine, and provide an automatic stacking machine for rice seedling trays. A film winding and packing device for the pallet with several seedling tray groups placed thereon is arranged on the blanking path. This design can wind and wrap the seedling tray groups and the pallet. During actual use, ropes and films can be arranged as needed to achieve winding and packing of the seedling tray groups or both packing and darkening treatment. This design can not only solve the situation of the seedling tray groups tipping over during the transportation process, but also solve the problem of darkening treatment, and can greatly relieve the labor intensity of workers and improve production efficiency.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions:

[0005] An automatic stacking machine for rice seedling trays includes a stacking device, a seedling tray group fork conveying device, and a film winding and packing device arranged in sequence. The film winding and packing device is used for winding and packing the pallet with several seedling tray groups placed thereon.

[0006] By adopting the above technical solutions, an automatic stacking machine for rice seedling trays is provided. The stacking machine is equipped with a film winding and packing device, which can effectively solve the situation of the seedling tray groups on the pallet tipping over during the transportation process. In addition, it can automatically wind the film to carry out darkening treatment on the seedling trays. This design can effectively reduce the labor intensity of workers and improve production efficiency.

[0007] The further setting of the present invention is that the pallet is slidably placed on the blanking path, and the film winding and packing device includes a vertical winding device.

[0008] By adopting the above technical solution, the position of the pallet in the solution is defined, and the specific functions of the film winding and packing device are defined. By using the vertical winding device, the upper, lower, left and right sides of the rectangular block composed of the seedling tray group and the pallet can be wrapped. This wrapping method is relatively simple, but it can firmly fix the seedling tray group on the pallet. In addition, by wrapping the upper and lower sides and the left and right sides at the same time, the darkening treatment of the seedling trays can be completely achieved. This winding method is simple and effective, and can effectively solve the defects of the traditional stacking machine.

[0009] The further setting of the present invention is that: the vertical winding device includes a ring frame perpendicular to the blanking path, and a slip ring is rotatably arranged on the ring frame. The rotation of the slip ring on the ring frame is driven by a driving motor on the ring frame. A film roll is arranged on the slip ring, and the blanking path is located inside the slip ring.

[0010] By adopting the above technical solution, the basic structure of the vertical winding device is defined.

[0011] The further setting of the present invention is that: a film pressing device for the film is arranged on the ring frame, and a cutting device for the unfolded film is arranged on the slip ring. After the film on the film roll is unfolded, it first passes through the cutting device, and then through the traction positioning of the film pressing device and the rotation of the slip ring, the vertical winding of the stacked pallets and several seedling tray groups is realized.

[0012] The further setting of the present invention is that: the film pressing device includes a rotating motor and an L-shaped bracket arranged on the output shaft of the rotating motor. The rotating motor and the outer rod body of the L-shaped bracket are perpendicular to the slip ring. A suction cup for the film is arranged on the outer rod body. When the rotating motor drives the L-shaped bracket to swing up and down reciprocally, the film at the cutting device can be pulled to the top of the seedling tray group above the pallet and pressed down for positioning through the suction cup.

[0013] By adopting the above technical solution, a film pressing device is arranged on the vertical winding device, which can press the film on the top of the seedling tray group on the pallet before winding, facilitating the winding operation of the film. The main part (L-shaped bracket) of the film pressing device is located inside the central hole of the slip ring. During use, the rotating motor drives the L-shaped bracket to rotate reciprocally, realizing the reciprocating swing of the outer rod of the L-shaped bracket between the cutting device and the top of the seedling tray group. When the outer rod of the L-shaped bracket reaches the upper part to dock with the film at the cutting device, a suction cup can be used to suck the film, and then through the downward swing of the L-shaped bracket, the film is pulled down to the top of the seedling tray, pressing the film tightly on the top of the seedling tray. While the slip ring rotates, the seedling tray group and the pallet move along the feeding path, and the film unrolled from the film roll is spirally wound around the seedling tray group and the pallet. At the same time, the L-shaped bracket remains stationary. As the seedling tray group and the pallet move along the feeding path, the L-shaped bracket gradually disengages from the seedling tray group. When the winding of the seedling tray group and the pallet is completed, the cutting device cuts the film, and the wound seedling tray group and the pallet continue to move along the feeding path until they reach the set position for storage.

[0014] The further setting of the present invention is that the cutting device includes a cutting mechanism and a film guiding mechanism. The cutting mechanism is on the side close to the film pressing device, and the film guiding mechanism is on the side close to the film roll. When the outer rod swings upward to dock with the cutting device, the suction cup on the outer rod is located between the cutting mechanism and the film guiding mechanism.

[0015] By adopting the above technical solution, the cooperation mode between the film pressing device and the cutting device is defined.

[0016] The further setting of the present invention is that the film is a black plastic film.

[0017] By adopting the above technical solution, using a black plastic film to wind the seedling tray combination and the pallet can not only achieve the purpose of packaging but also realize the darkening treatment of the seedling tray.

[0018] The further setting of the present invention is that the film winding and packaging device further includes a horizontal winding device.

[0019] By adopting the above technical solution, a horizontal winding device is arranged at the downstream position of the vertical winding device, which can realize the six-sided winding of the seedling tray group and the pallet, and can further improve the winding and wrapping ability of the seedling tray group and the pallet.

[0020] The further setting of the present invention is that the feeding path includes a first feeding conveyor section and a second feeding conveyor section. The vertical winding device of the film winding and packaging device winds and packages the stacked pallets and several seedling tray groups at the gap between the first feeding conveyor section and the second feeding conveyor section.

[0021] By adopting the above technical solution, the specific structure of the feeding path is defined.

[0022] A further setting of the present invention is that the tray stacking device is used to stack the seedling trays into a group of seedling trays, the fork conveyor for the group of seedling trays is used to transport and place the group of seedling trays on the pallet located on the blanking path, and several groups of seedling trays are evenly distributed horizontally on the pallet. The pallet is provided by a pallet storage device located beside the tray stacking device and configured with the blanking path.

[0023] By adopting the above technical solution, the tray stacking device is defined.

[0024] The main beneficial effects of the present invention are as follows:

[0025] 1. The film winding and packing device configured on the blanking path of the present invention can effectively solve the problem of the group of seedling trays on the pallet tipping over during transportation. In addition, it can automatically realize the darkening treatment of the seedling trays by winding the film, which can effectively reduce the labor intensity of workers and improve production efficiency.

[0026] 2. The present invention is provided with a film pressing device on the vertical winding device. Before winding, the film pressing device can pull the film located at the cutting device to the top of the group of seedling trays on the pallet and press it down, which can effectively improve the subsequent film winding operation.

[0027] 3. The present invention sets a horizontal winding device at the downstream position of the vertical winding device, which can realize six-sided winding of the group of seedling trays and the pallet, and can further improve the winding and wrapping ability of the group of seedling trays and the pallet.

The pallet 41 is provided by a pallet storage device 6 located beside the tray stacking device 1 and configured with the blanking path. The blanking path includes a first blanking conveying section 51 and a second blanking conveying section 52. The vertical winding device 31 of the film winding and packing device winds and packs the film on the stacked pallets 41 and a number of seedling tray groups 42 in the gap between the first blanking conveying section 51 and the second blanking conveying section 52.

[0037] The pallet 41 is slidably placed on the blanking path. The film winding and packing device includes a vertical winding device 31 and a horizontal winding device. The vertical winding device 31 and the horizontal winding device are sequentially arranged along the blanking path. For the structural principle of the horizontal winding device, reference can be made to the winding device shown in Figure 5 of the Chinese invention patent application "Application Publication No.: CN118992189A; Application Publication Date: November 22, 2024; Title: Film Coiling and Winding Device".

[0038] The vertical winding device 31 includes a ring frame 311 perpendicular to the blanking path. A slip ring 312 is rotatably arranged on the ring frame 311. The rotation of the slip ring 312 on the ring frame 311 is driven by a driving motor 313 on the ring frame 311. A film roll 314 is arranged on the slip ring 312. The blanking path is located in the central hole of the slip ring 312.

[0039] A film pressing device 316 for the film 3141 is provided on the ring frame 311. The film 3141 is a black plastic film. A cutting device 315 for the unfolded film 3141 is provided on the slip ring 312. After the film 3141 on the film roll 314 is unfolded, it first passes through the cutting device 315, and then through the traction positioning of the film pressing device 316 and the rotation of the slip ring 312, the vertical winding of the stacked pallets 41 and several seedling tray groups 42 is realized. The film pressing device 316 includes a rotating motor 3161 and an L-shaped bracket 3162 arranged on the output shaft of the rotating motor 3161.
