Description

Technical Field

[0001] The utility model relates to the field of pallet loading, in particular to a chain lifting pallet warehouse. Background Art

[0002] Pallets are often placed in stacks. When the stacked pallets need to be loaded one by one, the pallets are usually taken out one by one from top to bottom through a loading mechanism. This pallet loading process has the following problems:

[0003] First, the number of pallets that can be stacked is limited by the height of the loading mechanism;

[0004] Second, the loading mechanism usually needs to move in the X-axis, Y-axis and Z-axis, and the structure of the entire loading mechanism is relatively complicated;

[0005] Third, when the loading mechanism takes away the high pallet and the low pallet, the moving stroke is quite different, resulting in inconsistent time spent on taking the high and low materials;

[0006] Fourthly, in the process of taking away the pallets one by one from top to bottom, the total movement stroke of the loading mechanism is relatively long, resulting in low pallet loading efficiency. Summary of the invention

[0007] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a chain lifting pallet warehouse which can load stacked pallets one by one in a more optimal way from bottom to top with a simple structure.

[0008] In order to solve the above technical problems, the technical solution of the utility model is: a chain lifting pallet warehouse, comprising:

[0009] Pallet racks;

[0010] A lifting frame, which can be slidably mounted on the pallet storage rack up and down;

[0011] A chain lifting mechanism is installed on the pallet storage rack, and a lifting chain of the chain lifting mechanism is connected to the lifting rack.

[0012] The pallet lifting mechanism comprises two lifting components symmetrically slidably mounted on the lifting frame in the left-right direction, wherein the lifting components have fork teeth for extending into the fork holes of the pallet;

[0013] The opening and closing driving mechanism is installed on the lifting frame and connected with the two lifting components, and is used for driving the two lifting components to move toward each other until the fork tines are inserted into the fork holes; and driving the two lifting components to move backwards until the fork tines are separated from the fork holes.

[0014] To further facilitate the entry of stacked pallets into the pallet warehouse, the lifting frame and the two supporting components together enclose a space with an opening on the front side, and the pallet conveyor is configured to convey pallets from front to back, and the stacked pallets conveyed by the pallet conveyor enter the space from the front opening of the space.

[0015] In order to further transport the stacked pallets one by one from bottom to top, the lower end of the lifting frame extends downward beyond the fork tine, and when the fork tine faces the fork hole of the second pallet from bottom to top, the lower end of the lifting frame blocks the rear side of the lowest pallet.

[0016] A specific structure of a simple and reliable lifting assembly is further provided, the lifting assembly also includes a mounting rod and at least two material stopping rods, the mounting rod extends in the front-to-back direction, at least two material stopping rods are installed on the material stopping rod in parallel along the front-to-back direction and extend in the up-down direction, the fork teeth are installed on the inner side of the lower end of the material stopping rod.

[0017] To further facilitate the installation of the lifting assembly on the lifting frame, the lifting assembly also includes a sliding seat, the lower end of the sliding seat is fixedly connected to the rear end of the mounting rod, and the upper end is slidably mounted on the lifting frame in the left and right directions.

[0018] In order to further ensure that the lifting assembly is level front to back, a leveling roller with adjustable front and rear positions is installed at the rear end of each sliding seat.

[0019] Furthermore, the lifting frame is provided with a sliding rod axially located in the left and right directions, and the two lifting components are slidably mounted on the sliding rod. The opening and closing drive mechanism includes two cylinders, the cylinder bodies of the cylinders are mounted on the sliding rod, and the cylinder rod is connected to a lifting component.

[0020] After adopting the above technical solution, after stacks of pallets are placed in the space for accommodating pallets of the pallet warehouse rack, the chain lifting mechanism drives the lifting frame to rise and fall to a position where the fork tine faces the fork hole of the second pallet from the bottom to the top, and then the opening and closing driving mechanism drives the two lifting groups to move toward each other, and the fork tine is inserted into the fork hole of the second pallet from the bottom to the top, and the chain lifting mechanism drives the lifting frame to drive the other pallets except the bottom pallet to rise, so that the bottom pallet is separated and can be transported away, or other operations are taken to load it out. The pallet warehouse in the utility model can load the pallets therein one by one from the bottom to the top, without being limited by the height of the pallets, and has good flexibility in use, high loading efficiency, and the time spent on loading each pallet is consistent.

[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1 , 2 , 3, a chain lifting pallet warehouse, comprising:

[0027] Pallet rack 1;

[0028] The lifting frame 2 can be slidably mounted on the pallet storage frame 1 up and down;

[0029] The chain lifting mechanism 3 is installed on the pallet storage rack 1, and the lifting chain of the chain lifting mechanism 3 is connected to the lifting rack 2.

[0030] The pallet lifting mechanism comprises two lifting components 4 symmetrically slidably mounted on the lifting frame 2 in the left-right direction, and the lifting components 4 have fork teeth 41 for extending into the fork holes 51 of the pallet 5;

[0031] The opening and closing driving mechanism is installed on the lifting frame 2 and connected to the two lifting components 4, and is used to drive the two lifting components 4 to move toward each other until the fork teeth 41 are inserted into the fork holes 51; and drive the two lifting components 4 to move backwards until the fork teeth 41 are separated from the fork holes 51.

[0032] Specifically, after the stacked pallets 5 are placed in the space for accommodating the pallets 5 of the pallet storage rack 1, the chain lifting mechanism 3 drives the lifting frame to rise and fall to a position where the fork tine 41 is directly opposite to the fork hole 51 of the second pallet 5 from the bottom to the top, and then the opening and closing driving mechanism drives the two lifting components 4 to move toward each other, and the fork tine 41 is inserted into the fork hole 51 of the second pallet 5 from the bottom to the top, and the chain lifting mechanism 3 drives the lifting frame 21 to drive the other pallets 5 except the bottom pallet 5 to rise, and then the bottom pallet 5 is separated and can be transported away, or other operations are taken. The pallet storage in this embodiment can well transport the pallets 5 in the pallet storage from the bottom to the top one by one, without being restricted by the height of the pallet 5, and has good flexibility in use. Therefore, the pallet storage in this embodiment can well load the pallets 5 in it from the bottom to the top one by one, without being restricted by the height of the pallet 5, and has good flexibility in use; the loading efficiency is high; and the time spent on loading each pallet 5 is consistent. That is to say, this embodiment can load the stacked trays 5 one by one in a more optimal manner from bottom to top with a simple structure, thus solving the problems mentioned in the background art.

[0033] Preferably, if Figure 1 , Figure 2 and Figure 3 As shown, the lifting frame 2 and the two lifting assemblies 4 together enclose a space with an opening at the front side, and the pallet conveyor is configured to convey pallets 5 from front to back, and the stacked pallets 5 conveyed by the pallet conveyor enter the space from the front opening of the space.

[0034] In this way, the stacked pallets 5 can be directly transported into the pallet warehouse, which simplifies the operation of placing the stacked pallets 5 in the pallet warehouse.

[0035] More preferably, if Figure 3 As shown, the lower end of the lifting frame 2 extends downward beyond the fork tine 41 , and when the fork tine 41 faces the fork hole 51 of the second tray 5 from the bottom to the top, the lower end of the lifting frame 2 blocks the rear side of the lowest tray 5 .

[0036] In this way, after the fork tine 41 is inserted into the fork hole 51 of the second pallet 5 from the bottom to the top, the lifting frame 2 still blocks the rear side of the lowest pallet 5, and plays a blocking role on the pallet 5. After the chain lifting mechanism 3 drives the lifting frame 2 to drive the two lifting components 4 to lift the other pallets 5 except the lowest pallet 5, the lifting frame 2 rises to a height that does not block the lowest pallet 5, and the lowest pallet 5 can be transported backwards by the pallet conveyor from the lower channel formed by the rise of the lifting frame 2. In other words, after the stacked pallets 5 are placed in the pallet conveyor, the pallet conveyor transports the stacked pallets 5 to the pallet warehouse, and then the stacked pallets 5 can be transported backwards one by one from the bottom to the top, so as to enter the subsequent process, which greatly facilitates the operation of the upper pallet 5.

[0037] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the lifting assembly 4 also includes a mounting rod 42 and at least two material stopping rods 43, the mounting rod 42 extends in the front-to-back direction, at least two material stopping rods 43 are installed in parallel on the material stopping rod 43 along the front-to-back direction and extend in the up-down direction, and the fork teeth 41 are installed on the inner side of the lower end of the material stopping rod 43.

[0038] Specifically, the lifting assembly 4 of this structure is simple and reliable.

[0039] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the lifting assembly 4 further includes a sliding seat 44 , the lower end of the sliding seat 44 is fixedly connected to the rear end of the mounting rod 42 , and the upper end is slidably mounted on the lifting frame 2 in the left-right direction.

[0040] In this way, it is convenient to install the lifting assembly 4 on the lifting frame 2 .

[0041] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a leveling roller 8 whose front and rear positions are adjustable is installed at the rear end of each sliding seat 44 .

[0042] Specifically, the lifting assembly 4 can be leveled by moving the position of the leveling roller 8 in the front-to-back direction to prevent the front end or the rear end of the lifting assembly 4 from warping, thereby facilitating the long-term stable operation of the lifting assembly 4.

[0043] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a sliding rod 6 axially located in the left-right direction is installed on the lifting frame 2, and the two lifting components 4 are slidably fitted on the sliding rod 6. The opening and closing driving mechanism includes two cylinders 7, and the cylinder bodies of the cylinders 7 are installed on the sliding rod 6. The cylinder rod is connected to one lifting component 4. The two cylinders 7 are arranged back to back.

[0044] It should be noted that the two cylinders 7 can also be replaced by a two-way cylinder, or an oil cylinder, an electric cylinder, etc.

[0045] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
