[0059] Figure 1 It is a schematic structural diagram of a tray loading device according to one embodiment of the present disclosure. Figure 2 It is a structural schematic diagram of a tray loading device from another angle according to an embodiment of the present disclosure.

[0060] like Figure 1 and Figure 2 As shown, when the pallet loading device of the present invention is in use, the stacked pallets can be loaded one by one, and thus the materials placed on the pallets can be loaded.

[0061] Specifically, the pallet loading device of the present disclosure may include: a lifting device 100, a lifting seat 200, a pressing device 300, a conveying device 400 and other components.

[0062] In one embodiment, the tray loading device may include a vertical plate 500. In actual use, the vertical plate 500 is vertically arranged or approximately vertically arranged, so that the first direction described below can be a vertical direction or an approximately vertical direction.

[0063] A guide rail is provided on one surface of the vertical plate 500. More specifically, two guide rails may be provided, and the length direction of the guide rail is the first direction, so that the lifting seat 200 can slide along the guide rail, and accordingly, the lifting seat 200 can move along the first direction.

[0064] In the present disclosure, the lifting device 100 includes a screw rod 101 and a screw nut 102 disposed on the screw rod 101. In a preferred embodiment, both ends of the screw rod 101 are rotatably disposed on the vertical plate 500. For example, a bearing seat is disposed on the vertical plate 500, and a bearing is disposed in the bearing seat. Both ends of the screw rod 101 are rotatably supported by the bearings, and the screw rod 101 is limited by the bearings so that the screw rod 101 cannot move along the first direction.

[0065] In the present disclosure, the screw rod 101 is disposed in the area between the two guide rails, and the screw rod 101 is spaced apart from the surface of the vertical plate 500. In a preferred embodiment, the screw rod 101 may be a ball screw.

[0066] The nut 102 is rotatably disposed on the screw rod 101 . Accordingly, when the nut 102 is fixed to the lifting seat 200 and the screw rod 101 rotates, the nut 102 can move along the axial direction of the screw rod 101 , that is, along the first direction.

[0067] In the present disclosure, the screw rod 101 can be driven by a motor to rotate. Preferably, the motor can be a force-controlled servo motor, so that the lifting seat 200 has a higher movement accuracy in the first direction.

[0068] Specifically, the motor can be fixed to the other side of the vertical plate 500, and a driving wheel is fixed on the output shaft of the motor, and a driven wheel is fixed on the screw rod 101, and the driving wheel is connected to the driven wheel in a transmission manner, so that the motor can drive the screw rod 101 to rotate. More specifically, both the driving wheel and the driven wheel can be synchronous pulleys, and accordingly, the driving wheel and the driven wheel can be connected by a synchronous belt.

[0069] The lifting seat 200 is fixed to the nut 102 and is slidably disposed on the guide rail, so that the lifting device 100 can drive the lifting seat 200 to generate a lifting motion, that is, generate a motion in a first direction.

[0070] The vertical plate 500 is provided with a position detection component 501, and the position detection component 501 is used to detect the position of the lifting seat 200. Specifically, the position detection component 501 may include a beamforming switch, and accordingly, the lifting seat 200 is provided with a detection sheet, and when the detection sheet moves to a position between two beamforming switches, the beamforming switches will be triggered because the detection sheet blocks the signal transmission between the beamforming switches, and based on this, the position detection component 501 will be able to obtain the current position of the lifting seat 200.

[0071] In the present disclosure, the position detection component 501 can also be implemented by a distance sensor or other structures. In addition, when the position detection component 501 is implemented by a beam switch, the beam switch can also be fixed on the lifting seat 200, and accordingly, the detection sheet can be fixed on the vertical plate 500.

[0072] The lifting seat 200 is used to transport stacked pallets; specifically, the stacked pallets can be placed on the lifting seat 200 and move upward with the lifting seat 200, thereby realizing the transportation of the pallets. In addition, when the stacked pallets are transported by the conveying device 400 described below, the lifting seat 200 can move downward, and a new stacked pallet can be placed at this time.

[0073] In a preferred embodiment, a material detection sensor may be provided on the lifting seat 200. The material detection sensor may be a distance sensor, and the distance sensor is located below the stacked pallets and can detect the distance between the bottom pallet and the distance sensor. Accordingly, when the detection value of the distance sensor is within a preset range, such as 10 cm, it can be determined that there is a pallet on the lifting seat 200. When the detection value of the distance sensor is outside the preset range, it indicates that the bottom pallet has been transported, and it is determined that there is no pallet.

[0074] In the present disclosure, a material stopper 600 is also provided on the vertical plate 500. The pallet can contact the material stopper 600 during the upward conveyance process, so that the position of the pallet in one direction can be limited by the material stopper 600, making the stacked pallets easier to be conveyed by the conveying device 400 described below.

[0075] In the present disclosure, the pressing device 300 can be fixed to the base plate 700, and the base plate 700 can be arranged horizontally. In a preferred embodiment, the base plate 700 and the vertical plate 500 can be fixed to the same component, for example, fixed to the frame at the same time, so that the position between the base plate 700 and the vertical plate 500 can be relatively fixed.

[0076] Preferably, the number of the base plates 700 is two, and there is a gap between the two base plates 700 . At this time, when the stacked trays are driven by the lifting seat 200 and move upward, the stacked trays can pass through the gap between the two base plates 700 .

[0077] The pressing device 300 and the conveying device 400 are both provided in pairs, and one pressing device 300 and one conveying device 400 are fixed on each substrate 700. Thus, the present invention discloses that the two pressing devices 300 are symmetrically arranged; and / or, the two conveying devices 400 are symmetrically arranged, and Figure 1 In the direction shown, the two pressing devices 300 are respectively located at the front and rear sides of the stacked pallets, and correspondingly, the two conveying devices 400 are also respectively located at the front and rear sides of the stacked pallets.

[0078] The pressing device 300 can be driven to approach the stacked trays and press the trays; specifically, the pressing device 300 includes: a pressing driving device 310 and a pressing claw 320 .

[0079] The material pressing driving device 310 may be a cylinder, and the cylinder may be fixed to the base plate 700 via a support structure such as a bracket, so that the material pressing claw 320 can be set at a reasonable height.

[0080] The pressing claw 320 is arranged on the pressing driving device 310 and is driven by the pressing driving device 310 to move. Specifically, the movement generated by the pressing driving device 310 is approaching or moving away from the pallet, so that when the pressing driving device 310 drives the pressing claw 320 to approach the pallet, it can contact the pallet and keep the pallet at the current position. Accordingly, when the conveying device 400 conveys the pallet, the pallet below the conveyed pallet will not be conveyed together with the pallet above.

[0081] In a preferred embodiment, the press claw 320 includes a base portion 321 and a bent portion 322, wherein the base portion 321 is fixed to the press drive device 310 and is substantially vertically arranged. The bent portion 322 is arranged at the upper end of the base portion 321 and extends outwardly from a surface of the base portion 321 in a direction substantially perpendicular to the base portion 321 by a preset length, so that the position of the tray can be restricted by the cooperation between the bent portion 322 and the tray.

[0082] In the present disclosure, the number of the bending portions 322 can be set to more than two. In a specific embodiment of the present disclosure, the bending portions 322 are set to two. Those skilled in the art should know that it is also possible to set the bending portions 322 to other numbers.

[0083] The conveying device 400 is used to convey the pallet above the pallet pressed by the pressing device 300, that is, the conveying device 400 can convey the top pallet of the stack of pallets, and correspondingly, the pressing device 300 can hold the second pallet from the top in the stack of pallets, so that the pallets are conveyed one by one through the cooperation of the pressing device 300 and the conveying device 400.

[0084] In a specific embodiment, the conveying device 400 may include: a conveying drive device 410, an intermediate plate 420, a clamping drive device 430, a conveying claw 440 and other components.

[0085] In the present disclosure, two columns 710 are disposed on the base plate 700, and the two columns 710 are disposed in parallel with each other. For example, the two columns 710 are both disposed vertically.

[0086] A sliding block is disposed on one side wall of the column 710 , and a sliding rail is slidably disposed in the sliding block so that the sliding block can move relative to the sliding block along a first direction.

[0087] The slide rail is fixed with an intermediate plate 420. In the present disclosure, the intermediate plate 420 can be directly fixed to the upper end of the slide rail, or indirectly fixed to the slide rail through a connector, that is, the intermediate plate 420 in the present disclosure moves synchronously with the slide rail.

[0088] The intermediate plate 420 can be driven by the conveying drive device 410 to produce movement in the first direction; specifically, the conveying drive device 410 can be a cylinder, the cylinder body of the cylinder can be fixed to the base plate 700 or the column 710, and correspondingly, the piston rod of the cylinder can be fixed to the intermediate plate 420, thereby the intermediate plate 420 can be driven up and down by the cylinder, so that the intermediate plate 420 produces movement in the first direction.

[0089] The clamping drive device 430 is disposed on the middle plate 420 and can generate a second direction of motion, the second direction being different from the first direction; more preferably, the first direction is perpendicular to the second direction. In a specific embodiment, the second direction is a direction approaching or moving away from the tray.

[0090] The conveying claw 440 is disposed on the clamping driving device 430 and can be driven by the clamping driving device 430 to generate a movement in the second direction.

[0091] Specifically, when the clamping driving device 430 is in motion, the conveying claw 440 is driven by the clamping driving device 430 to approach the tray, and clamps the tray to be conveyed through the cooperation of the two conveying devices.

[0092] In the present disclosure, a groove is provided on the conveying claw 440. When the conveying claw 440 moves in a direction approaching the pressing claw 320, at least a portion of the pressing claw 320 of the pressing device 300 can be located in the groove, so that the movement between the conveying device 400 and the pressing device 300 will not interfere.

[0093] When the conveying device 400 disclosed in the present invention is in use, the conveying driving device is first controlled to operate to drive the conveying claw 440 to a preset position, and then the clamping driving device 430 is controlled to operate to clamp the pallet; and then the conveying driving device 410 is controlled to operate to lift the pallet, so that the pallet is separated from other pallets and conveyed.

[0094] After the delivery of one pallet is completed, the force-controlled servo motor can drive the stacked pallets to move upward by the height of one pallet, so that the stacked pallets are transferred to the position to be delivered.

[0095] At the same time, the beam switch can also be used to detect whether the top tray of the stacked trays has reached the preset position, so that the force-controlled servo motor can be started and stopped according to the signal of the beam switch. In other words, the beam switch can accurately determine the rising height of the tray, achieving a closed-loop control effect on the force-controlled servo motor.

[0096] The driving device disclosed in the present invention is mostly implemented by a cylinder, which has high stability and can ensure accurate and stable tray loading under high-speed operation.

[0097] The pallet loading device disclosed in the present invention has a high degree of automation, can reduce the labor intensity of manual operations, and solves the problems raised in the background technology.
