Description

Technical Field

[0001] The present application relates to corrugated paper production equipment, and in particular to a stacking and lifting device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of corrugated core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] After the corrugated cardboard is pasted, cut, and bundled, it will be stacked on a pallet for transportation. At this time, a palletizing and lifting device is needed to assist. In actual use, the existing palletizing and lifting device cannot, firstly, be used to position the pallet. During the lifting process, it is easy for the device to shake, which will cause the stacked cardboard to collapse. Secondly, it cannot limit the stacking height of the cardboard, resulting in the height of the cardboard stacked on each pallet being inconsistent.

[0004] In order to solve the above problems, the present application discloses a palletizing and lifting device. Utility Model Content

[0031] Example

[0032] In order to solve the problem that the stacking lifting device in the prior art cannot accurately position the pallet and cannot ensure that the cardboard is stacked to the set height, Figure 1 As shown, the present application discloses a palletizing and lifting device, comprising: two bases 10, the two bases 10 being arranged relatively and spaced apart;

[0033] The first frame 20 is slidably disposed between the two bases 10. Linear guide rails 60 are provided on opposite sides of the two bases 10. Sliding seats 70 are provided around the first frame 20 and slidably connected to the four linear guide rails 60.

[0034] A lifting drive mechanism 30 is provided on the two bases 10 and is connected to the first frame 20 to drive the first frame 20 to perform a lifting movement;

[0035] The roller conveyor line 40 is provided above the first frame 20 to drive the pallet for transportation;

[0036] The pallet positioning mechanism 50 is disposed below the first frame 20 and can extend from the roller gap of the roller conveyor line 40 to position the pallet.

[0037] Based on the above structure, during the specific implementation process, the operator places the pallet to be stacked on the roller conveyor line 40 and controls the pallet positioning mechanism 50 to position the pallet. After that, the robot can stack the cardboard on the pallet. After the cardboard on the pallet is stacked to a certain height, the pallet positioning mechanism 50 will be reset, and at this time, the roller conveyor line 40 will send the pallet out.

[0038] In order to connect the lifting drive mechanism 30 with the first frame 20, the present application further provides an inverted L-shaped connecting frame 80 on opposite sides of the first frame 20. The lifting drive mechanism 30 is connected to the two inverted L-shaped connecting frames 80. As for the lifting drive mechanism 30 of the present application, the following two structures can be selected:

[0039] The first one, reference Figure 4 As shown, the lifting drive mechanism 30 includes a lifting drive motor 32 and two diverters 33. The two diverters 33 are respectively arranged below the opposite side of the two bases 10. The two diverters 33 are connected by a transmission shaft 34. The lifting drive motor 32 is installed on one of the diverters 33. The output ends of the two diverters 33 are respectively connected to a worm 35 connected to the inverted L-shaped connecting frame 80. When the lifting drive motor 32 drives one diverter 33 to move, the other diverter 33 will be driven to rotate through the transmission shaft 34. At this time, the two worms 35 connected to the two diverters 33 will automatically lift the first frame 20.

[0040] The second one, reference Figure 3 As shown, the lifting drive mechanism 30 includes two hydraulic cylinders 31, which are respectively arranged below the opposite side of the two bases 10. The two piston rods of the two hydraulic cylinders 31 are respectively connected to the two inverted L-shaped connecting frames 80. Under the action of the two hydraulic cylinders 31, the first frame 20 will be automatically lifted.

[0041] Based on the above two situations, the structure of the second lifting drive mechanism 30 is relatively simple and low in cost, and can be adopted in a timely manner during the specific implementation process. This application will not elaborate on it in detail.

[0042] In one embodiment, reference Figure 2 As shown, the pallet positioning mechanism 50 of the present application includes an upper base plate 51, a lower base plate 52, a cylinder 53 and four positioning columns 54. Two support rods 55 are provided at the bottom of the first frame 20. The lower base plate 52 is fixed below the two support rods 55. The cylinder 53 is provided below the lower base plate 52. The upper base plate 51 is provided between the first frame 20 and the two support rods 55 and is connected to the piston rod of the cylinder 53. The four positioning columns 54 are opposite to each other and pass through the gap between the rollers of the roller conveyor line 40. It should be noted here that the pallet used in practice must have four positioning holes corresponding to the positions of the positioning columns 54 at its bottom (not shown in this application). When the control cylinder 53 drives the upper base plate 51 to rise, the four positioning columns 54 of the present application will be inserted into the four positioning holes at the bottom of the pallet, thereby realizing the positioning of the pallet.

[0043] In order to ensure the smooth lifting and lowering of the upper base plate 51, the present application also provides four guide sleeves 56 around the inner part of the lower base plate 52, and four guide columns 57 are provided around the bottom of the upper base plate 51 to pass through the four guide sleeves 56. The bottom of each two guide columns 57 is respectively connected to a limit block 58. When the cylinder 53 drives the upper base plate 51 to lift, the two limit blocks 58 can limit the lifting height of the four positioning columns 54, thereby avoiding lifting the pallet from the roller conveyor line 40.

[0044] The second frame 90 is connected to the bottom of the two bases 10 of the present application, and stabilizing tubes 100 are connected to the opposite sides of the middle of the two bases 10. In this way, the stability of the entire stacking and lifting device is improved, and the device has higher usability.

[0045] In the present application, trigger plates 120 are respectively provided on one side of the two inverted L-shaped connecting frames 80 close to the two upright seats, and trigger switches 130 corresponding to the trigger plates 120 are respectively provided above the opposite sides of the two bases 10. After the cardboards on the pallet are stacked to the moving height, the first frame 20 will be lifted to the set height. When the trigger plate 120 triggers the trigger switch 130, the entire machine will stop.

[0046] In order to achieve rapid positioning of the pallet, the conveying end and the opposite sides of the roller conveyor line 40 of the present application are provided with baffles 110 for blocking the pallet. Based on the setting of the above baffles 110, the pallet can be accurately placed in a fixed position on the roller conveyor line 40.
