Description
Technical Field
[0001] The present application relates to the technical field of pallet transportation, and in particular to a rotating table for pallet transfer. Background Art
[0002] In the freeze-drying workshop, materials need to go through processes such as pre-treatment, temporary storage in cold storage, freeze-drying, and sorting and packaging. When materials are transferred between processes, they are generally spread flat on pallets and transported through conveyor belts. When materials need to be transferred to the conveyor belt of the next process, a robot is used to support the transfer pallet.
[0003] However, when the robot arm grabs the pallet, it needs to accurately align with the specific grabbing point on the pallet to ensure that the robot arm can grab the pallet smoothly. During the transfer of the pallet on the conveyor belt, the position of the pallet on the conveyor belt may be offset due to external forces. The offset of the pallet position will cause the deviation of the grabbing point of the robot arm, resulting in the robot arm being unable to grab the pallet smoothly, and then the pallet cannot be smoothly transferred to the next process, the pallet transfer efficiency becomes low, and there are obvious shortcomings. Utility Model Content
[0004] In order to improve the transfer efficiency of pallets, the present application provides a rotating table for pallet transfer.
[0005] The present application provides a pallet transfer rotating table using the following technical solutions:
[0006] A rotating table for pallet transfer comprises a work surface, a fixed plate and a platform frame are arranged on the work surface, a supporting table surface for supporting the pallet is arranged on the platform frame, a rotating assembly is arranged on the fixed plate, the rotating assembly comprises a rotating motor arranged on the fixed plate, the output shaft of the rotating motor is fixedly connected with a connecting shaft, a connecting plate is arranged on the connecting shaft, a fixing piece is arranged on the connecting plate, the connecting plate is fixedly connected to the supporting table surface via the fixing piece, and the platform frame is rotatably connected to the work surface.
[0007] By adopting the above technical solution, during the transfer process, the conveyor belt transfers the pallet to the supporting table of the platform frame, and then the rotating motor is started. The rotating motor drives the connecting plate to rotate through the connecting shaft. Under the fixed connection of the fixing part, the connecting plate drives the supporting table to rotate, and the supporting table drives the pallet to rotate on the work table. During the rotation of the pallet, the position of the pallet grabbing point is adjusted. When the grabbing point on the pallet rotates to an angle suitable for the robot arm to grab, the rotating motor is turned off. At this time, the robot arm grabs the pallet and transfers it to the next process. The position of the pallet is adjusted through the rotating component, which reduces the probability of the pallet being unable to be successfully grabbed due to position offset, increases the probability of the pallet being successfully transferred, and thus improves the transfer efficiency of the pallet.
[0008] Optionally, a plurality of threaded holes are provided on the connecting plate and the supporting table surface, and the fixing members are fixing bolts threadedly connected in the threaded holes.
[0009] By adopting the above technical solution, the setting of multiple fixing bolts realizes a tight connection between the connecting plate and the support table, reducing the possibility of relative displacement between the connecting plate and the support table, thereby improving the stability of the support table during rotation and reducing the possibility of the pallet shaking and detaching from the support table. At the same time, the setting of the fixing bolts realizes a detachable connection between the connecting plate and the support table, making it convenient for workers to replace the corresponding support table according to pallets of different specifications.
[0010] Optionally, a cylindrical bracket is provided on the fixed plate, and the cylindrical bracket is rotatably connected to the bottom surface of the support table. A plane bearing is rotatably connected inside the cylindrical bracket, and the plane bearing is fixedly sleeved on the outer surface of the connecting shaft. The end face of the plane bearing abuts against the bottom surface of the connecting plate, and the connecting plate is rotatably connected to the plane bearing.
[0011] By adopting the above technical solution, during the rotation of the platform frame, all the loads on the connecting plate are concentrated on the connecting shaft. When the connecting shaft is subjected to a large load, unstable rotation may occur. The setting of the plane bearing balances the high-intensity load on the connecting shaft, thereby improving the stability of the connecting shaft during rotation.
[0012] Optionally, a through hole is formed on the connecting plate, a connecting piece is disposed in the through hole, the connecting shaft is slidably inserted into the through hole, and the connecting plate is detachably connected to the connecting shaft via the connecting piece.
[0013] By adopting the above technical solution, after long-term use of the connecting plate, wear may occur at the connection between the connecting plate and the connecting shaft, which directly affects the stability of the platform frame rotation. At this time, the worker can replace the connecting plate on the connecting shaft by disassembling the connecting parts, effectively reducing the occurrence of unstable rotation of the platform frame caused by wear of the connecting plate, thereby further improving the transfer efficiency of the pallet.
[0014] Optionally, the connecting member is a flat key, and the through hole and the outer surface of the connecting shaft are provided with key slots that are interconnected, and the flat key is inserted into the key slots.
[0015] By adopting the above technical solution, when it is necessary to disassemble the connecting plate, the flat key is taken out of the keyway and then the connecting plate is slid outward to separate the connecting plate from the connecting shaft. When it is necessary to install the connecting plate, the keyway on the connecting plate is aligned with the keyway on the connecting shaft, and then the connecting shaft is passed through the through hole on the connecting plate, and finally the flat key is inserted into the keyway. Under the connection of the flat key, the connecting plate and the connecting shaft are connected as a whole and will not rotate relative to each other.
[0016] Optionally, two pallet racks are disposed on the platform frame, the two pallet racks are symmetrical about the center of the support table, and the pallet racks are spaced apart from the support table on the platform frame.
[0017] By adopting the above technical solution, when the pallet is transferred to the platform frame, the support table supports the middle of the pallet, and the two pallet racks support the two sides of the pallet respectively. The setting of the pallet racks expands the contact area between the platform frame and the pallet, thereby improving the stability of the pallet on the platform frame. At the same time, the intervals between the pallet racks and the support table leave grabbing space for the robotic arm, so that the robotic arm can more easily grab the pallet from the platform frame, thereby improving the convenience of the robotic arm operation.
[0018] Optionally, a shielding cover is provided on the platform frame, the shielding cover is provided on the outer peripheral side of the supporting table surface, and the shielding cover is fixedly connected to the supporting table surface by bolts.
[0019] By adopting the above technical solution, the shielding cover shields the supporting table and the non-rotating component, providing a closed and safe environment, thereby increasing the service life of the rotating motor. At the same time, the supporting table and the shielding cover are fixedly connected by bolts, which reduces the possibility of relative displacement between the supporting table and the shielding cover during rotation, further improving the stability of the tray during rotation.
[0020] Optionally, a plurality of universal wheels are provided at the bottom of the platform frame, and the bottom surfaces of the universal wheels are in contact with the surface of the work table.
[0021] By adopting the above technical solution, under the rolling of the universal wheels, the rotation process of the platform frame on the work surface is smoother and more stable, thereby reducing the possibility of the pallet detaching from the platform frame during the rotation process and improving the transportation efficiency of the pallet.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The present application sets a rotating component, which drives the pallet to rotate on the work surface, thereby adjusting the position of the pallet grabbing point, reducing the probability that the pallet cannot be grabbed smoothly due to position offset, and increasing the probability of the pallet being successfully transferred, thereby improving the transfer efficiency of the pallet;

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The embodiment of the present application discloses a rotating table for transferring pallets.
[0032] Reference Figure 1A pallet transfer rotating table includes a work surface 1, on which a fixed plate 2 and a platform frame 3 are arranged, wherein the fixed plate 2 is fixedly connected to the work surface 1 by screws, and the platform frame 3 is rotatably connected to the work surface 1, and a support table 31 and two pallet racks 32 are fixedly welded to the platform frame 3, and the two pallet racks 32 are respectively arranged on opposite sides of the platform frame 3 and symmetrical about the center of the support table 31, and the two pallet racks 32 and the support table 31 are arranged on the platform frame 3 at intervals, wherein the support table 31 is used to support the middle position of the pallet, and the pallet rack 32 is used to support the opposite sides of the pallet.
[0033] When the pallet carrying the materials needs to be transferred to the next process, the pallet is transported to the platform frame 3 by the conveyor belt. With the joint support of the support table 31 and the pallet rack 32, the stability of the pallet on the platform frame 3 is improved. At the same time, the intervals between the pallet rack 32 and the support table 31 leave a grabbing space for the robot arm, so that the robot arm can grab the pallet from the platform frame 3 more easily, thereby improving the convenience of the robot arm operation.
[0034] Reference Figure 1 and Figure 2 A cylinder bracket 21 is welded on the fixed plate 2, and the top end of the cylinder bracket 21 is rotatably connected to the bottom surface of the support table 31. A rotating component 4 is arranged inside the cylinder bracket 21. The rotating component 4 includes a rotating motor 41 fixedly mounted on the surface of the fixed plate 2. The output shaft of the rotating motor 41 is fixedly connected to a connecting shaft 42. A connecting plate 43 is arranged on the connecting shaft 42. The connecting plate 43 is fixedly connected to the support table 31 through a fixing member 5.
[0035] Reference Figure 1 and Figure 2 A plurality of threaded holes 6 are provided on the surface of the connecting plate 43 and the supporting table 31, and the plurality of threaded holes 6 are distributed in a circle on the connecting plate 43. The fixing member 5 is a fixing bolt 51 threadedly connected in the threaded hole 6. The setting of the fixing bolt 51 improves the stability between the connecting plate 43 and the supporting table 31, and also realizes the detachable connection between the connecting plate 43 and the platform frame 3, which is convenient for workers to replace the corresponding platform frame 3 according to pallets of different specifications.
[0036] After the pallet is transferred to the platform frame 3, the rotating motor 41 is started. The rotating motor 41 drives the connecting plate 43 to rotate through the connecting shaft 42. Under the fastening connection of the fixing bolts 51, the connecting plate 43 drives the supporting table 31 to rotate, and at the same time drives the two pallet frames 32 to rotate through the connection of the platform frame 3, thereby realizing the rotation of the pallet on the work table 1. During the rotation of the pallet, the position of the pallet grabbing point is adjusted. When the grabbing point on the pallet rotates to an angle suitable for the robot arm to grab, the rotating motor 41 is turned off. At this time, the robot arm grabs the pallet and transfers it to the next process. The adjustment of the pallet position is realized through the rotating component 4, which reduces the probability of the pallet being unable to be successfully grabbed due to position offset, increases the probability of the pallet being successfully transferred, and thus improves the transfer efficiency of the pallet.
[0037] Reference Figure 1 and Figure 2 A plane bearing 7 is rotatably connected inside the cylindrical bracket 21. The plane bearing 7 is fixedly connected to the outer surface of the connecting shaft 42 by screws. The end face of the plane bearing 7 abuts against the bottom surface of the connecting plate 43. The connecting plate 43 is rotatably connected to the plane bearing 7. The setting of the plane bearing 7 balances the high-strength load on the connecting shaft 42 and improves the stability of the connecting shaft 42 during rotation.
[0038] Reference Figure 3 and Figure 4 A through hole 8 is provided on the surface of the connecting plate 43, the connecting shaft 42 is slidably connected in the through hole 8 and is detachably connected to the connecting plate 43 through a connecting piece 9, and key grooves 10 that are interconnected are provided on the side walls of the through hole 8 and the connecting shaft 42, and the connecting piece 9 is a flat key 11 that is inserted into the two key grooves 10.
[0039] After long-term use of the connecting plate 43, wear may occur at the connection between the connecting plate 43 and the connecting shaft 42, which directly affects the rotation stability of the platform frame 3. At this time, the worker removes the flat key 11 from the key slot 10, and then slides the connecting plate 43 outward to separate the connecting plate 43 from the connecting shaft 42. When a new connecting plate 43 needs to be installed, the key slot 10 on the connecting plate 43 is aligned with the key slot 10 on the connecting shaft 42, and then the connecting shaft 42 is passed through the through hole 8 on the connecting plate 43, and finally the flat key 11 is inserted into the key slot 10. Under the connection of the flat key 11, the connecting plate 43 and the connecting shaft 42 are connected as a whole and will not rotate relative to each other.
[0040] Reference Figure 3 and Figure 4A shielding cover 12 is provided on the platform frame 3, and the shielding cover 12 is provided on the outer peripheral side of the supporting table 31. The shielding cover 12 is fixedly connected to the supporting table 31 by bolts 13. The shielding cover 12 shields the supporting table 31 and does not provide a closed safety environment for the rotating component 4, thereby improving the service life of the rotating motor 41. At the same time, the supporting table 31 and the shielding cover 12 are fixedly connected by the bolts 13, which reduces the possibility of relative displacement between the supporting table 31 and the shielding cover 12 during rotation, and further improves the stability of the tray during rotation.
[0041] Reference Figure 3 and Figure 4 A plurality of universal wheels 14 are provided at the bottom of the platform frame 3 . In the present embodiment, the number of the universal wheels 14 is six, and the six universal wheels 14 are all rollingly connected to the work surface 1 .
[0042] With the rolling of the universal wheels 14 , the platform frame 3 rotates more smoothly and stably on the work surface 1 , thereby reducing the possibility of the pallet detaching from the platform frame 3 during the rotation process and improving the transportation efficiency of the pallet.
[0043] The implementation principle of the rotating table for pallet transfer in the embodiment of the present application is as follows: after the pallet is transferred to the platform frame 3, the rotating motor 41 is started, and the rotating motor 41 drives the connecting plate 43 to rotate through the connecting shaft 42. Under the fastening connection of the fixing bolts 51, the connecting plate 43 drives the supporting table 31 to rotate, and at the same time drives the two pallet frames 32 to rotate through the connection of the platform frame 3, thereby realizing the rotation of the pallet on the work table 1, and adjusting the position of the pallet grabbing point during the rotation of the pallet. When the grabbing point on the pallet rotates to an angle suitable for the robot arm to grab, the rotating motor 41 is turned off. At this time, the robot arm grabs the pallet and transfers it to the next process. The adjustment of the pallet position is realized through the rotating component 4, which reduces the probability that the pallet cannot be successfully grabbed due to position offset, increases the probability that the pallet is successfully transferred, and thus improves the transfer efficiency of the pallet.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
