[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figures 1 to 4 The loading and unloading platform device of the embodiment of the utility model comprises a frame 100, a conveying mechanism 200, a pallet 300 and a locking structure 400. The conveying mechanism 200 is arranged on the frame 100; the pallet 300 is detachably arranged on the conveying mechanism 200 and can be moved away from the conveying mechanism 200 along the conveying direction of the conveying mechanism 200; the locking structure 400 is movably arranged on the conveying mechanism 200, and the locking structure 400 can move to a position where the pallet 300 is locked or unlocked relative to the conveying mechanism 200.

[0034] Place the pallet 300 on the conveying mechanism 200 and load the workpiece. When the locking structure 400 moves to a position where the pallet 300 is unlocked relative to the conveying mechanism 200, the pallet 300 can move along the conveying direction of the conveying mechanism 200 to detach from the conveying mechanism 200 and move to a designated position. When the pallet 300 is no longer needed to convey the workpiece, the production staff can move the locking structure 400 to a position where the pallet 300 is locked relative to the conveying mechanism 200. At this time, the pallet 300 will not accidentally fall even if it is pushed by an external force, thereby improving the safety of the loading and unloading platform device.

[0035] In the embodiment, the locking structure 400 includes a latch member 410, and the tray 300 is provided with a first limiting hole 310. The latch member 410 is movably connected to the conveying mechanism 200 and can be inserted into or disengaged from the first limiting hole 310. The latch member 410 is movably connected to the conveying mechanism 200. When the latch member 410 is inserted into the first limiting hole 310 of the tray 300, the latch member 410 locks the position of the tray 300, making it difficult for the tray 300 to move relative to the conveying mechanism; when the latch member 410 is disengaged from the first limiting hole 310, the latch member 410 no longer blocks the tray 300, and the tray 300 can move normally along the conveying direction of the conveying mechanism 200 to convey the workpiece.

[0036] Specifically, the conveying direction of the conveying mechanism 200 is the front-to-back direction, the hole axis direction of the first limiting hole 310 is perpendicular to the conveying direction of the conveying mechanism 200, and the moving direction of the latch member 410 is also perpendicular to the conveying direction of the conveying mechanism 200, so that when the latch member 410 is inserted into the first limiting hole 310, the limiting effect on the tray 300 is better. In this embodiment, the hole axis of the first limiting hole 310 is arranged in the vertical direction, and the moving direction of the latch member 410 is also arranged in the vertical direction. It is conceivable that the hole axis direction of the first limiting hole 310 and the moving direction of the latch member 410 can also be other directions, for example, the hole axis direction of the first limiting hole 310 and the moving direction of the latch member 410 both have a certain angle with the conveying direction of the conveying mechanism 200.

[0037] In the embodiment, the conveying mechanism 200 is provided with a threaded through hole, and the latch member 410 is provided with a stud portion, which is threadedly connected to the threaded through hole. The latch member 410 is connected to the conveying mechanism 200 by a threaded connection. When the latch member 410 rotates, the latch member 410 as a whole can move relative to the conveying mechanism 200 to insert into or disengage from the first limiting hole 310. The movement of the latch member 410 is achieved by threaded engagement, which can facilitate the latch member 410 to remain in a specified position, which is conducive to the locking structure 400 to lock or unlock the tray 300.

[0038] It is conceivable that the latch member 410 can also move relative to the conveying mechanism 200 in other ways. For example, the conveying mechanism 200 is provided with a guide hole, and the latch member 410 is slidably inserted into the guide hole, so that the latch member 410 can be slidably connected to the conveying mechanism 200 to be inserted into or out of the first limit hole 310. It is conceivable that a slide groove can be provided on the conveying mechanism 200, and a slider portion can be provided on the latch member 410, and the slider portion can be movably connected to the slide groove, so that the latch member 410 can be slidably inserted into or out of the first limit hole 310.

[0039] In the embodiment, the locking structure 400 includes a catch 420, which is pivotally connected to the conveying mechanism 200. The tray 300 is provided with a second limiting hole 320. The catch 420 can be rotated to enter or disengage from the second limiting hole 320, and the rotation axis of the catch 420 is parallel to the conveying direction of the conveying mechanism 200. When it is necessary to further fix the position of the tray 300 relative to the conveying mechanism 200, the catch 420 can be rotated to enter the second limiting hole 320, and the catch 420 can also lock the position of the tray 300; when the tray 300 needs to move, the catch 420 can be rotated to disengage from the second limiting hole 320, and the catch 420 can unlock the position of the tray 300. Specifically, the catch 420 is a block.

[0040] In an embodiment, the conveying mechanism 200 includes a conveying frame 210 and a plurality of rollers 220, the rollers 220 are rotatably connected to the conveying frame 210, the conveying direction of the conveying mechanism 200 is the front-to-back direction, the rollers 220 are arranged in the left-right direction, and all the rollers 220 are arranged in the front-to-back direction. The pallet 300 is conveyed by a plurality of rollers 220 arranged in the front-to-back direction, and the structure is simple and easy to implement. When the pallet 300 is placed on the rollers 220 and the locking structure 400 unlocks the position of the pallet 300, the production personnel can manually push the pallet 300 lightly, and the pallet 300 can be moved along the conveying direction of the conveying mechanism 200, so as to remove the pallet 300 from one end of the conveying mechanism 200, so as to transfer the pallet 300 to the turnover trolley docked with one end of the conveying mechanism 200, which is relatively convenient to use and reduces the labor intensity of the production personnel. When the tray 300 is locked by the locking structure 400 , it is difficult to push the tray 300 so that the tray 300 moves along the conveying direction of the conveying mechanism 200 , thereby preventing the tray 300 from accidentally falling.

[0041] Specifically, the conveying mechanism 200 may have two, three, four or more rollers 220, and those skilled in the art may configure the rollers 220 according to actual needs. Further, in some embodiments, all rollers 220 may be driven to rotate by a motor in conjunction with a chain sprocket, further improving the automation of the conveying mechanism 200.

[0042] It is conceivable that the conveying mechanism 200 may also be other types of conveying mechanisms 200. For example, the conveying mechanism 200 includes a conveying frame 210 and a conveyor belt, and the conveyor belt is movably connected to the conveying frame 210. When the pallet 300 is placed on the conveyor belt, the pallet 300 can be moved along the conveying direction through the conveyor belt; or the conveying mechanism 200 includes a conveying frame 210 and rollers, and the pallet 300 is conveyed by the rollers.

[0043] In the embodiment, the tray 300 includes a plate body 330 and three support bars 340. The support bars 340 are located below the plate body 330. The support bars 340 are arranged in the front-to-back direction. All the support bars 340 are arranged at intervals in the left-to-right direction. The length of the support bars 340 is greater than the distance between two adjacent rollers 220. When the tray 300 is placed on the conveying mechanism 200, the support bars 340 are placed across two or more rollers 220 to reduce the contact area between the tray 300 and the rollers 220, thereby reducing the friction between the tray 300 and the conveying mechanism 200; at the same time, the material consumption and weight of the tray 300 are saved, and the height of the plate body 330 is also increased, which meets the use requirements.

[0044] It is conceivable that the tray 300 may also have two, four or more supporting bars 340 , and those skilled in the art may configure the supporting bars 340 according to actual needs.

[0045] Preferably, both ends of the support bar 340 may have chamfered surfaces to facilitate the support bar 340 to step into different rollers 220 when the tray 300 moves.

[0046] In the embodiment, the conveyor frame 210 includes a crossbeam 211 and two longitudinal beams 212, one end of the longitudinal beam 212 is connected to the end of the crossbeam 211, the two longitudinal beams 212 are respectively connected to the two ends of the crossbeam 211, and the two ends of the roller 220 are respectively rotatably connected to the two longitudinal beams 212, and the upper end of the roller 220 is lower than the upper end of the longitudinal beam 212. The above-mentioned conveyor frame 210 is U-shaped, and the upper end of the roller 220 is lower than the upper end of the longitudinal beam 212, so that when the support bar 340 of the pallet 300 is placed on the roller 220, the longitudinal beam 212 can also limit the support bar 340 to the left and right, reducing the risk of the pallet 300 accidentally falling from the left and right sides of the conveying mechanism 200, and further improving safety.

[0047] When the tray 300 is placed on the roller 220 , the plate 330 is higher than the upper end of the conveyor frame 210 , so that the plate 330 can be made larger without being limited by the size of the conveyor frame 210 , thereby being able to carry large-sized workpieces or a larger number of workpieces.

[0048] In the embodiment, the frame 100 includes a main frame 110, a lifting seat 120 and a lifting drive, the lifting seat 120 is movably arranged on the main frame 110 in a vertical direction, the lifting drive is arranged on the main frame 110 and can drive the lifting seat 120 to move, and the conveying mechanism 200 is arranged on the lifting seat 120. The lifting drive can drive the lifting seat 120 to rise and fall, so as to drive the conveying mechanism 200 to rise and fall. Firstly, in the process of continuously stacking workpieces, the lifting seat 120 can be gradually lowered so that the stacking position of the workpiece remains basically unchanged, which is conducive to stacking workpieces using a manipulator; secondly, the lifting seat 120 can drive the conveying mechanism 200 and the tray 300 to rise and fall to a height that docks with the turnover trolley, so as to facilitate the tray 300 to move along the conveying direction of the conveying mechanism 200 to separate from the conveying mechanism 200 and enter the turnover trolley.

[0049] Specifically, the lifting seat 120 can be movably connected to the main frame 110 along the vertical direction through a guide column and guide sleeve structure or a slide rail and slider structure. At this time, the lifting drive can be a screw, a screw nut and a motor. The screw is arranged vertically, and the screw nut is fixedly connected to the lifting seat 120 and cooperates with the screw thread. When the motor drives the screw to rotate, it can drive the lifting seat 120 to rise and fall; or the lifting drive adopts a structure such as an oil cylinder, an electric cylinder, etc. to output linear power.

[0050] In the embodiment, the conveying mechanism 200 is detachably disposed on the lifting seat 120, so that the maintenance of the conveying mechanism 200 and the lifting seat 120 is more convenient. When one of the lifting seat 120 and the conveying mechanism 200 needs maintenance, the two can be separated for separate maintenance.

[0051] In the embodiment, the conveying mechanism 200 is connected to the lifting seat 120 by screw locking. By screw locking, the conveying mechanism 200 is detachably connected, the structure is simple, and it is easy to implement. It is conceivable that the conveying mechanism 200 can also be detachably connected to the lifting seat 120 by other means, for example, the conveying mechanism 200 is plugged into the lifting seat 120 or the conveying mechanism 200 is clamped on the lifting seat 120, etc.

[0052] The utility model also discloses a rubber lagging machine, comprising a rubber lagging machine body, the above-mentioned loading and unloading platform device, a position detection sensor 500 and a control module. The above-mentioned loading and unloading platform device is arranged on the rubber lagging machine body; the position detection sensor 500 is arranged on the conveying mechanism 200 and is used to detect the position of the locking structure 400; the control module is arranged on the rubber lagging machine body and is electrically connected to the position detection sensor 500.

[0053] When the position detection sensor 500 detects that the locking structure 400 is in the position of locking the tray 300, the control module controls the main body of the rubber lagging machine to be unable to start; when the position sensor detects that the locking structure 400 is in the state of unlocking the tray 300, the control module allows the main body of the rubber lagging machine to start. The above-mentioned rubber lagging machine has good production safety.

[0054] Specifically, the position detection sensor 500 may be a photoelectric sensor or a contact switch, etc., and the control module may be a circuit board or a single-chip microcomputer including a control circuit.
