Technical Field

[0001] The utility model relates to the field of pallet arranging technical equipment, in particular to a pallet arranging machine. Background Art

[0002] Pallets are usually stacked one by one by people. Manually stacking pallets is laborious and inefficient, and the workers' labor intensity is high. There is a pallet sorting machine on the market. After use, existing pallets are usually sorted and stacked in a designated area of the factory for subsequent use using a pallet sorting machine. The existing pallet sorting machine includes two parallel left and right side frames fixed to the ground and a pallet lifting mechanism. A pallet stacking space is formed between the two side frames. The pallet lifting mechanism is set on the two side frames and can lift the pallet up or down along the height direction of the side frames. However, the space between the two side frames in the existing pallet sorting machine is fixed and cannot be adjusted, so the pallet sorting machine can only stack pallets of a certain size and specifications. The specifications of existing pallets are not fixed, resulting in pallets of other specifications not being able to be stacked using the existing pallet sorting machine. The existing pallet sorting machine has a narrow range of applications for stacking pallets. Utility Model Content

[0003] The utility model aims to provide a pallet arranging machine which can be used to arrange and stack pallets of various specifications and sizes.

[0004] In order to solve the above technical problems, the specific solution adopted by the utility model is a pallet sorting machine: comprising two vertical stacking frames, a top plate, a transverse telescopic mechanism and a lifting mechanism. The two vertical stacking frames enclose a stacking space for stacking pallets. The top plate is suspended and fixed directly above the two vertical stacking frames by four supporting legs. The lifting mechanism is arranged on the vertical stacking frames to push the pallets up or down.

[0005] The lateral telescopic mechanism includes a sliding assembly and a driving assembly. The sliding assembly allows the two vertical code frames to slide in relative or opposite directions. The driving assembly is arranged on the top plate and is used to drive the two vertical code frames to slide on the sliding assembly. The driving assembly includes a long shaft and a first driving motor for driving the long shaft to rotate. The long shaft is distributed along the moving direction of the two vertical code frames. A worm is installed at each end of the long shaft. Any worm is meshed with a worm wheel. The worm wheels are coaxially mounted with a first transmission gear. The first transmission gear is meshed with a second transmission gear. The second transmission gear is coaxially mounted with a third transmission gear. The third transmission gear is meshed with a push rack, and the push rack is fixed to the vertical code frame on the corresponding side.

[0006] As another optimization solution of the above-mentioned pallet sorting machine: the sliding assembly includes two slide rails arranged between two vertical code frames, and a slider for slidingly cooperating with the corresponding slide rails is provided at the bottom of the vertical code frame.

[0007] As another optimization solution for the above-mentioned pallet sorting machine: the lifting mechanism includes multiple groups of lifting components respectively arranged on the vertical code frames, and any group of lifting components includes a lifting platform, a sliding rack and a second drive motor. The sliding rack is arranged along the height direction of the corresponding vertical code frame, and a sliding frame is slidably installed on the sliding rack. The sliding frame is fixedly connected to the second drive motor and the lifting platform respectively, and a lifting gear for engaging with the sliding rack is installed on the output shaft of the second drive motor.

[0008] As another optimization solution of the above-mentioned pallet sorting machine: each vertical stacking frame is provided with a plurality of lifting gaps along its height direction for installing the lifting components and allowing them to rise or fall.

[0009] As another optimization solution of the above-mentioned pallet sorting machine: two sets of lifting components are installed on each vertical stacking frame, and two lifting platforms on the same vertical stacking frame are connected.

[0010] As another optimization solution of the above-mentioned pallet sorting machine: a lift for assisting in taking out the pallets is provided between the two vertical code frames, and a lifting cylinder for ascending or descending the lift is provided at the bottom of the lift.

[0012] As another optimization solution of the above-mentioned pallet sorting machine: the first drive motor is fixed to the upper end surface of the top plate through a mounting base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The first driving motor in the driving assembly of the utility model can drive the long shaft to rotate, and the worm gears at both ends of the long shaft can mesh with the corresponding side worm gears and drive them to rotate. The first transmission gear coaxially arranged with the worm gear rotates synchronously and drives the second transmission gear meshed with it to rotate. The rotating second transmission gear drives the third transmission gear coaxially arranged with it to rotate. The rotation of the third transmission gear can drive the push rack meshed with it and fixed on the vertical stacking frame to move. The two vertical stacking frames slide in relative or opposite directions through the sliding assembly under the push of the push rack, so that the stacking space enclosed by the two vertical stacking frames gradually increases or decreases as it moves, so that the sorting machine can adjust the size of the stacking space according to the specifications and size of the pallets. Compared with the existing sorting machine that can only sort and stack pallets of one specification, the sorting machine can be used for sorting and stacking pallets of various specifications and sizes, and has a wider range of applications.

[0015] 2. In the present invention, the lifting assembly arranged on the two vertical stacking frames can be driven by the lifting drive motor to drive the driving gear meshing with the sliding rack to move along the height direction of the vertical stacking frame, and the lifting platform can be driven up or down by the sliding frame. The lifting platform can lift the pallet and move it above the vertical stacking frame, freeing up the stacking space below the vertical stacking frame, facilitating the subsequent stacking and sorting of the pallets, thereby realizing the longitudinal stacking and sorting of the pallets of the sorting machine.

[0016] 3. The lift in the utility model can be raised and lowered in the stacking space. The lift can support the pallet and increase the lifting height of the entire pallet, so that it is convenient to dock with the lifting platform and support the pallet to the stacking space above. At the same time, the lift lifts the pallet, making it convenient for a forklift to insert under the pallet and take out the pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts not described in detail in the following embodiments of the present invention, such as the models and specifications of the first drive motor and the second drive motor, the meshing transmission of the worm and the turbine, etc., should be immediately known to those skilled in the art or should be known to the prior art.

[0022] like Figure 1-3As shown, a pallet organizer includes two vertical stacking frames 1, a top plate 2, a transverse telescopic mechanism, and an elevator 5. The two vertical stacking frames 1 are arranged vertically parallel to each other, forming a stacking space for stacking pallets. The top plate 2 is suspended and fixed directly above the tops of the two vertical stacking frames 1 by four support legs 201. The lower ends of the four support legs 201 are fixed to the ground, and the upper ends of the four support legs 201 are fixed to the lower end surface of the top plate 2, leaving a gap between the top plate 2 and the tops of the two vertical stacking frames 1.

[0023] The lateral telescopic mechanism allows the two vertical code frames 1 to move laterally to adjust the size of the stacking space, so that the sorting machine can be suitable for the stacking of pallets of various specifications and sizes. The lateral telescopic mechanism includes a driving assembly 3 arranged on the top plate 2 and a sliding assembly 6 arranged at the bottom of the two vertical code frames 1. The sliding assembly 6 allows the two vertical code frames 1 to move laterally in relative or opposite directions. The sliding assembly 6 includes two slide rails 601. The two slide rails 601 are arranged in parallel between the bottoms of the two vertical code frames 1. Two sliders 602 are slidably installed on each slide rail 601. The sliders 602 are respectively fixed to the bottom of the corresponding vertical code frames 1 so that the two vertical code frames 1 can slide along the slide rails 601 under the drive of the driving assembly 3.

[0024] The drive assembly 3 includes a first drive motor 301, a long shaft 302 and two push racks 306. The first drive motor 301 is fixed to the middle part of the upper end surface of the top plate 2 through a mounting base. A worm gear reducer 3011 is installed on the output shaft of the first drive motor 301. The long shaft 302 is passed through the worm gear reducer 3011. A built-in worm (not shown in the figure) is fixed to the end of the output shaft of the first drive motor 301 in the worm gear reducer 3011. A built-in worm is installed on the long shaft 302 in the worm gear reducer 3011. The built-in worm wheel is engaged with the built-in worm. The first drive motor 301 can drive the built-in worm to rotate and engage with the built-in worm wheel to drive the long shaft 302 to rotate.

[0025] A worm 303 is fixed to each end of the long shaft 302. Each worm 303 engages with a worm wheel 304. The worm wheel 304 is mounted on a vertical mounting shaft (not shown). The mounting shaft is attached to one side of the corresponding worm 303 via an L-shaped mounting bracket (not shown). One end of the L-shaped mounting bracket is fixed to the upper end surface of the top plate 2, and the other end of the L-shaped mounting bracket is mounted with a bearing for the mounting shaft to pass through and rotate.

[0026] A first transmission gear 305 is installed at the lower end of the mounting shaft, and a second transmission gear 307 meshing with the first transmission gear 305 is respectively provided on both sides of the first transmission gear 305. The second transmission gears 307 are respectively fixed to the upper end of the vertically arranged rotating shaft (not shown in the figure), and a third transmission gear 308 is fixed to the lower end of the rotating shaft. The rotating shaft is stably set on one side of the first transmission gear 305 through a bracket (not shown in the figure). The structure of this bracket is consistent with the structure of the above-mentioned L-shaped mounting bracket. One end of the bracket is fixed to the lower end surface of the top plate 2, and the other end is provided with a bearing for the lower end of the rotating shaft to pass through and rotate, so that the second transmission gear 307 is stably located on both sides of the first transmission gear 305 and meshes with it for transmission.

[0027] The push rack 306 is arranged parallel to the long shaft 302, and one end of the push rack 306 is fixed to the inner side wall of the upper end of the vertical code frame 1 on the corresponding side, and the push rack 306 is located between the two third transmission gears 308 and meshes with them respectively, so that the rotating long shaft 302 can drive the two worm gears 304 to rotate through the worm gears 303 at both ends, and the rotating worm gears 304 drive the first transmission gear 305 to rotate through the mounting shaft, and the rotating first transmission gear 305 drives the second transmission gears 307 on both sides to rotate, and the second transmission gear 307 drives the third transmission gear 308 to rotate through the rotating shaft. Then, the two push racks 306 move in opposite directions with the rotation of the third transmission gear 308, thereby pushing the two vertical code frames 1 to move in opposite directions, thereby realizing the adjustment of the stacking space size between the two vertical code frames 1, and thus making the sorting machine suitable for stacking pallets of various specifications and sizes.

[0028] The two vertical stacking frames 1 are provided with two lifting gaps 101, spaced apart along their height. The two lifting gaps 101 on any vertical stacking frame 1 divide it into three vertically distributed vertical plates. An elevator 5 is mounted on the vertical stacking frames 1 to propel the pallet up or down. The elevator 5 comprises four lifting assemblies 401, one mounted in each lifting gap 101 on the vertical stacking frame 1.

[0029] Each set of lifting components 401 includes a lifting platform 2014, a sliding rack 4011, and a second drive motor 4013. The sliding rack 4011 is fixed to the side of the vertical plate on the side corresponding to the lifting gap 101 and is arranged along its height direction. A sliding frame 4012 is slidably mounted on the sliding rack 4011. The body of the second drive motor 4013 is fixedly connected to the outside of the sliding frame 4012. The output shaft of the second drive motor 4013 located within the sliding frame 4012 is mounted with a lifting gear (not shown in the figure) for engaging with the corresponding sliding rack 4011. The lifting platform 2014 is fixed to the inside of the sliding frame 4012. The horizontal surface of the lifting platform 2014 protrudes from the lifting gap 101 to facilitate supporting the pallet. The two lifting platforms 2014 on the same vertical code frame 1 are connected by a connecting rod to enable synchronous lifting.

[0030] The second drive motor 4013 can drive the lifting gear to rotate and drive the sliding frame 4012 to engage and move with the lifting platform 2014 along the length direction of the sliding rack 4011, thereby pushing the pallet placed on the lifting platform 2014 to rise or fall along the height direction of the vertical stacking frame 1. The lifting platform 2014 can lift the pallet placed below the stacking space and move it to the top of the stacking space, thereby freeing up the space below the stacking space to facilitate the subsequent stacking and removal of pallets.

[0031] Furthermore, a lift 5 is installed on the ground between the two vertical code frames 1. The lift 5 includes a lifting platform 2014 surface and a lifting cylinder for driving the lifting platform 2014 surface to rise or fall. A mounting groove for installing the lifting cylinder and the lifting platform 2014 surface is provided on the ground. The cylinder body of the lifting cylinder is fixed in the mounting groove, and the telescopic end of the lifting cylinder is set upward and fixed to the bottom surface of the lifting platform 2014 surface.

[0032] When a pallet needs to be taken out, the lifting platform 2014 lowers the pallet and places it on the lifting table of the elevator 5. The forklift for transferring the pallet can quickly insert under the pallets on both sides of the elevator 5. After the elevator 5 is lowered, the pallet falls exactly on the forklift, making it easy to take the pallet out. At the same time, when pallets need to be stacked, the forklift inserts on both sides of the elevator 5 and places the pallet on the lifting table to complete the stacking. In addition, it also makes it easier for the lifting platform 2014 to lower and support the pallets on the elevator 5 to free up space for stacking.

[0033] Furthermore, a group of articulated frames are respectively arranged on both sides of the lifting cylinder in the installation groove, and any group of articulated frames includes two lifting rods, the middle parts of the two lifting rods are hingedly connected and arranged in an X shape, the upper ends of the two lifting rods are hinged to the bottom surface of the lifting platform 2014, and the lower ends of the two lifting rods are hinged in the installation groove. The setting of the articulated frames can assist in supporting the lifting platform 2014 to stably rise or fall when supporting the pallet.
