[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1 to 8 The mechanism shown includes a support 1 for simultaneously loading and unloading multiple pallets. A support component is mounted on the support 1 to support a horizontal pallet 2 and to lift the horizontal pallet 2.

[0031] Specifically, the supporting component includes two L-shaped support plates 41 and a transmission unit that drives the two L-shaped support plates 41 to move synchronously. The transmission unit is mounted on the bracket 1, and the two L-shaped support plates 41 are fixed to the transmission unit. Both L-shaped support plates 41 are arranged horizontally in the front-to-back direction and have an L-shaped vertical cross-section. The two L-shaped support plates 41 are symmetrically arranged and together form a support frame for placing a horizontally positioned pallet 2.

[0032] Specifically, the transmission unit is divided into two parts, each of which is connected to an L-shaped support plate 41 and includes two auxiliary drive shafts 36 and two chains 43. The two auxiliary drive shafts 36 are arranged horizontally in the front-to-back direction and are rotatably mounted on the bracket 1, with the two auxiliary drive shafts 36 facing each other vertically.

[0033] Two sprockets 4 are fixedly mounted on each auxiliary drive shaft 36. The two sprockets 4 on the upper auxiliary drive shaft 36 correspond one-to-one with the two sprockets 4 on the lower auxiliary drive shaft 36. Each chain 43 is connected to two corresponding sprockets 4.

[0034] The L-shaped support plate 41 is fixedly connected to two chains 43, and the auxiliary drive shaft 36 located above is connected to the drive component for transmission.

[0035] Two chains 43 located on the same part of the transmission section are fixedly connected to multiple L-shaped support plates 41. The multiple L-shaped support plates 41 on the two parts of the transmission section together form multiple load-bearing brackets, which are evenly distributed on the chains 43.

[0036] A top plate 3 is fixedly installed on the top of the bracket 1. A drive component is installed on the top plate 3, and the drive component is in transmission cooperation with two auxiliary drive shafts 36 located above the supporting component. An outer cover is fixedly installed on the top plate 3 to cover the drive component and prevent personal injury.

[0037] Specifically, the drive component includes a power source 31, which typically consists of a servo motor and a speed reducer. Both the servo motor and the speed reducer are fixed on the top plate 3. The output shaft of the motor is coaxially and fixedly connected to the input shaft of the speed reducer.

[0038] A main drive shaft 34 is rotatably mounted on the top plate 3. A driven gear 32 and two first bevel gears 33 are fixedly sleeved on the main drive shaft 34. A driving gear 37 is fixedly sleeved on the output shaft of the reducer, and the driving gear 37 meshes with the driven gear 32. Two second bevel gears 38 are fixedly sleeved on the two auxiliary drive shafts 36 located above. The two first bevel gears 33 correspond one-to-one with the two second bevel gears 38, and each second bevel gear 38 meshes with the corresponding first bevel gear 33.

[0039] In this embodiment, the main drive shaft 34 and all auxiliary drive shafts 36 are rotatably connected to the bracket 1 via bearings. The bracket 1 is fixedly mounted with bearing seats 35, and the bearings are fixed inside the bearing seats 35.

[0040] Two side baffles 62 extend horizontally forward from the front of the bracket 1. The two side baffles 62 are parallel to each other and located at the same height. Both side baffles 62 are stably supported by multiple vertical support legs 61.

[0041] The two side baffles 62 are the same as the L-shaped support plate 41. The two side baffles 62 are symmetrically arranged and together form a loading platform that cooperates with the support bracket. The loading platform is opposite to the support bracket and is used for the sliding guidance and support of the pallet 2.

[0042] A rear baffle 42 is fixedly installed at the rear of the bracket 1, and the rear baffle 42 corresponds to the front and rear of the loading platform. The load-bearing bracket is located between the rear baffle 42 and the loading platform. A front baffle 63 is fixedly installed at the front end of each of the two side baffles 62.

[0043] The loading platform is located in the middle of the support 1 along the height direction. The area above the loading platform is the unloading area, and the area below the loading platform is the loading area.

[0044] A support rail 5 extending forward in a horizontal direction is fixedly installed at the front of the bracket 1, and the support rail 5 is located below the platform. A tray-removing component for removing the tray 2 from the supporting component or placing the tray 2 into the supporting component is installed on the support rail 5, and the tray-removing component is in transmission cooperation with the tray 2.

[0045] Specifically, the tray-retrieving component includes a transverse cylinder 51 and a gripper cylinder 53. In this embodiment, the transverse cylinder 51 is a rodless cylinder, with its cylinder body (guide rod) parallel to the support guide rail 5, and its slide (output end) in a limited sliding engagement with the support guide rail 5. The transverse cylinder 51 is fixedly connected to the support guide rail 5, and a mounting plate 52 is fixedly mounted on the output end (slide) of the transverse cylinder 51. The gripper cylinder 53 is fixedly mounted on the mounting plate 52.

[0046] In this embodiment, the gripper cylinder 53 is a pneumatic finger. Each of the two grippers, i.e., the two fingers, of the gripper cylinder 53 is fixedly mounted with a vertically placed positioning post 54. The front end of the tray 2 is provided with a slot corresponding to the positioning post 54, and each positioning post 54 is engaged with the corresponding slot in a contact-type locking transmission cooperation.

[0047] The slots on the tray 2 all penetrate the tray 2, and the front end of the tray 2 is provided with a notch for the positioning post 54 to slide into and out of the corresponding slot.

[0048] A PLC controller is fixedly mounted on bracket 1. The PLC controller is electrically connected to the transverse cylinder 51, the gripper cylinder 53, and the motor. An operation panel 6 is fixedly mounted on bracket 1 and is electrically connected to the PLC controller. This technology is prior art and will not be described in detail here.

[0049] The bottom of bracket 1 is equipped with casters for transport and feet for support.

[0050] Working principle: The operator manually places the pallet 2, filled with materials, onto the support frame in the loading area. Simultaneously, the information for pallet 2 is recorded on the operation panel 6 of the support 1. Then, based on actual production needs, the corresponding pallet 2 position information is sent to the drive unit via the PLC controller. The drive unit drives the transmission unit of the support component to lift the pallet 2 from the support frame to the loading platform. Afterwards, the pallet retrieval unit pulls the pallet 2 out of the support frame and onto the loading platform.

[0051] When the material on the pallet 2 on the platform is used up or when it is necessary to replace it with another pallet 2, the pallet retrieval component pushes the pallet 2 on the platform back to the support bracket.

[0052] Subsequently, the drive unit again drives the transmission part of the supporting unit to lift the pallet 2 on the support bracket to the unloading area. If the material on pallet 2 is used up, the operator removes the empty pallet 2 from the unloading area. This cycle is repeated.

[0053] The process by which the drive component drives the transmission part of the supporting component to lift the pallet 2 on the support bracket is as follows: The output shaft of the motor drives the input shaft of the reducer to rotate. The input shaft of the reducer drives the output shaft to rotate through an internal mechanism. The output shaft of the reducer drives the drive gear 37 to rotate. The drive gear 37 drives the driven gear 32 to rotate. The driven gear 32 drives the main drive shaft 34 to rotate. The main drive shaft 34 drives two first bevel gears 33 to rotate. The two first bevel gears 33 drive two second bevel gears 38 to rotate. The two second bevel gears 38 drive two auxiliary drive shafts 36 to rotate. The two auxiliary drive shafts 36 drive four sprockets 4 to rotate. The four sprockets 4 drive four chains 43 for transmission. The four chains 43 synchronously drive the connected L-shaped support plate 41 to move.

[0054] The process by which the tray-retrieving component pulls the tray 2 from the support bracket and onto the loading platform is as follows: The transverse cylinder 51 drives the slide to move closer to the tray 2, which in turn moves the mounting plate 52 closer to the tray 2. The mounting plate 52 then moves the gripper cylinder 53 closer to the tray 2, and the two grippers of the gripper cylinder 53 move the two positioning pins 54 from the notches on the tray 2 into the corresponding slots. Afterward, the two grippers of the gripper cylinder 53 move the two positioning pins 54 away from the tray 2 and finally engage with it. Finally, the transverse cylinder 51 drives the slide to move away from the bracket 1, while simultaneously, the two grippers of the gripper cylinder 53 move the two positioning pins 54 to pull the tray 2 out and onto the loading platform.

[0055] The process of the tray removal component pushing the tray 2 on the platform back to the support bracket is as follows: the transverse cylinder 51 drives the slide to slide close to the bracket 1, and at the same time, the two grippers of the gripper cylinder 53 drive the two positioning pins 54 to push the tray 2 back to the support bracket.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
