Description

Technical Field

[0001] The present application relates to the field of pallet technology, and in particular to a pallet turning machine. Background Art

[0002] In the freeze-drying workshop, materials need to go through steps such as pre-treatment, temporary storage in cold storage, freeze-drying, sorting and packaging. Materials are transferred between the equipment in each process, usually by laying them flat on pallets for transfer.

[0003] However, during the sorting and packaging steps, the freeze-dried materials need to be taken out from the pallet and collected. However, traditional taking-out operations are mostly manual operations. Workers need to take the pallet carrying the materials from the conveyor belt, pour the materials on the pallet into the collection box, and then put the empty pallet on the conveyor belt for the next process. The entire taking-out process requires repeated manual operations. When the number of pallets is large, it takes a lot of time and manpower to complete the material taking-out and collection operations. The material collection efficiency is low, which is obviously insufficient. Utility Model Content

[0004] In order to improve the material collection efficiency, the present application provides a pallet turning machine.

[0005] The present application provides a pallet turning machine adopting the following technical solution:

[0006] A pallet turning machine comprises a bracket and a first conveyor belt, wherein a pallet for holding materials is arranged on the first conveyor belt, and grabbing components for grabbing the pallet are arranged at opposite ends of the bracket, and the grabbing components comprise a fixed disk rotatably connected to the outer side wall of the bracket, and a plurality of pallet grabs are evenly distributed at equal intervals on the fixed disk, and collecting frames are arranged on the opposite outer sides of the bracket, and two of the collecting frames are surrounded on the outer side wall of the bracket, and a driving component for driving the fixed disk to rotate is arranged in the bracket.

[0007] By adopting the above technical solution, the freeze-dried material is transferred to the tray of the first conveyor belt. When the first conveyor belt drives the tray to the vicinity of the moving bracket, the tray grab supports the tray, the driving component starts and drives the fixed tray to rotate, the rotation of the fixed tray drives the tray grab to rotate, and the tray grab drives the tray to automatically flip over. During the flipping process, the material on the tray is poured into the collection frame. The entire collection process realizes automatic flipping of the tray through the driving component and the grabbing component. There is no need for workers to repeatedly remove the tray and flip the tray to dump the material, which saves time and effort, thereby improving the material collection efficiency.

[0008] Optionally, the driving assembly includes a rotating motor disposed on the bracket, the output shaft of the rotating motor is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected between opposite side walls of the bracket, and the two fixed plates are respectively fixedly connected to both ends of the rotating shaft.

[0009] By adopting the above technical solution, after the pallet grabs the carrying pallet, the rotating motor is started, the rotating motor drives the rotating shaft to rotate, the rotation of the rotating shaft drives the two fixed disks to rotate synchronously, and the rotation of the fixed disks drives the pallet grab to rotate, thereby realizing the automatic flipping of the pallet.

[0010] Optionally, the tray is provided with supporting edges on both sides opposite to each other, a limiting groove is provided on the tray grip, the supporting edge of the tray abuts against the inner side wall of the limiting groove, and the bottom surface of the supporting edge is slidably matched with the limiting groove. The horizontal height of the bottom surface of the limiting groove is on the same horizontal line as the bottom surface height of the supporting edge.

[0011] By adopting the above technical solution, when the first conveyor belt drives the pallet to the vicinity of the pallet gripper, the two supporting edges on the pallet slide into the limiting groove and abut against the limiting groove. At this time, the pallet is mounted between the two pallet grippers, thereby realizing the support of the pallet by the pallet gripper. Such a structure is simple and while realizing the detachable connection between the pallet and the pallet gripper, it improves the connection strength between the pallet and the pallet gripper, so that the pallet will not easily separate from the pallet gripper due to external forces such as collision or vibration during movement.

[0012] Optionally, a positioning plate is provided in the limiting groove, a pressure sensor is provided on the positioning plate, and the pressure sensor is electrically connected to the rotating motor through a control system.

[0013] By adopting the above technical solution, when the pallet collides with the positioning plate, the pressure sensor receives the pressure signal and controls the rotating motor to start automatically, and the rotating motor drives the push plate to flip. The setting of the positioning plate limits the moving distance of the pallet on the pallet grip, thereby fixing the flipping position of the pallet. At the same time, the pressure sensor is used to further improve the degree of automation of the pallet flipping process. Such a setting ensures the uniformity of the flipping positions of each pallet, ensuring that the material can be smoothly dumped into the collection frame.

[0014] Optionally, a second conveyor belt is provided on a side of the support away from the first conveyor belt, and the second conveyor belt is used to convey the tray emptied of materials.

[0015] By adopting the above technical solution, after the driving assembly drives the pallet to completely flip from one side of the bracket to the other side, the material in the pallet is completely dumped into the collection frame, and at the same time, the empty pallet is inverted on the second conveyor belt and transported to the next process under the conveyance of the second conveyor belt for subsequent use. The setting of the second conveyor belt realizes the automatic collection of the pallet with emptied materials, ensuring the continuity of the entire collection process.

[0016] Optionally, a shielding cover is provided on the bracket, and the shielding cover is provided on the outer surface of the bracket, and the top plate of the shielding cover is an inverted V-shaped plate.

[0017] By adopting the above technical solution, the setting of the shielding cover provides a sealed environment for the driving component inside the bracket, thereby protecting the safety of the driving component inside the bracket and reducing the impact of external environmental factors on the driving component. At the same time, under the guidance effect of the top plate of the shielding cover, the material dumped on the tray can be more smoothly collected in the collection frame, reducing the probability of material accumulation on the top of the shielding plate, thereby further improving the material collection efficiency.

[0018] Optionally, grooves are provided on the outer sides of the shielding cover, and connecting components are provided in the grooves. The collection frame is detachably connected to the bracket via the connecting components. The connecting components include a connecting shaft rotatably connected in the groove, a clamping block is fixedly connected to the outer side wall of the connecting shaft, a protrusion that is plug-inly matched with the groove is provided on the collection frame, and a clamping groove that is clamped with the clamping block is provided on the protrusion. A torsion spring is sleeved on the connecting shaft, one end of the torsion spring is connected to the inner side wall of the groove, and the other end is connected to the connecting shaft. When the torsion spring is in a natural state, the clamping block is clamped in the inside of the clamping groove.

[0019] By adopting the above technical solution, when the materials in the collection frame are fully collected, the worker pulls the block outward to disengage it from the slot. At this time, the protrusion lacks the limit of the block, and the worker can easily remove the collection frame from the bracket to centrally process the materials. When the collection frame needs to be installed, the worker pulls the block outward to disengage the block from the groove, and then inserts the protrusion into the groove and cancels the force on the block. Under the elastic force of the torsion spring, the torsion spring drives the connecting shaft to rotate, and the connecting shaft drives the block to engage into the slot. The detachable connection of the collection frame on the outer wall of the bracket is achieved through the engagement of the block and the slot, and the disassembly and installation process is convenient and quick, which is convenient for workers to operate and further improves the material collection efficiency.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The embodiment of the present application is provided with a grabbing assembly and a flipping assembly. When the first conveyor belt drives the tray to move near the bracket, the tray automatically slides into the limiting groove, and then the grabbing assembly is driven by the driving assembly to realize the automatic flipping of the tray. The entire collection process does not require workers to repeatedly take down the tray and flip the tray to dump the materials, which saves time and effort, thereby improving the collection efficiency of the materials;

[0022] 2. In the embodiment of the present application, a positioning plate is set. When the pallet collides with the positioning plate, the pressure sensor receives the pressure signal and controls the rotating motor to start automatically. The rotating motor drives the push plate to flip. The setting of the positioning plate limits the moving distance of the pallet on the pallet grip, thereby fixing the flipping position of the pallet. At the same time, the pressure sensor is used to further improve the degree of automation of the pallet flipping process. Such a setting ensures the uniformity of the flipping positions of each pallet, ensuring that the material can be smoothly dumped into the collection frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a pallet turning machine.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2A pallet turning machine comprises a bracket 1, a first conveyor belt 2 and a second conveyor belt 3, the bracket 1 is arranged between the first conveyor belt 2 and the second conveyor belt 3, the first conveyor belt 2 carries a pallet 4 for containing freeze-dried materials, and two opposite ends of the bracket 1 are provided with grabbing components 5 for grabbing the pallet 4, the grabbing component 5 comprises a fixed disk 51 rotatably connected to the outer wall of the bracket 1, and a plurality of pallet grabs 52 are evenly distributed on the outer peripheral side wall of each fixed disk 51 at equal distances. In this embodiment, the number of pallet grabs 52 is four. In the initial position, one of the pallet grabs 52 is parallel to the length direction of the first conveyor belt 2 and the second conveyor belt 3, and a driving component 6 for driving the two fixed disks 51 to rotate synchronously is arranged inside the bracket 1, and collecting frames 7 are fixedly installed on the two opposite end faces of the bracket 1, and the two collecting frames 7 are together surrounding the outer peripheral side wall of the bracket 1, and the collecting frame 7 is used to collect the materials dumped from the pallet 4.

[0032] Reference Figure 1 and Figure 2 The driving assembly 6 includes a rotating motor 61 fixedly mounted on the side wall of the bracket 1, the output shaft of the rotating motor 61 is fixedly connected to a rotating shaft 62, the rotating shaft 62 is rotatably connected between the opposite side walls of the bracket 1, and the two fixed plates 51 are fixedly connected to the two ends of the rotating shaft 62 respectively.

[0033] Reference Figure 1 and Figure 2 The freeze-dried material is transferred to the tray 4 of the first conveyor belt 2 through the transfer equipment. When the first conveyor belt 2 drives the tray 4 to move near the bracket 1, the rotating motor 61 is started, and the rotating motor 61 drives the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 drives the two fixed disks 51 to rotate synchronously. The rotation of the fixed disk 51 drives the tray grip 52 to rotate. The tray grip 52 drives the tray 4 to automatically flip over. During the flipping process, the material on the tray 4 is poured into the collection frame 7. The entire collection process realizes the automatic flipping of the tray 4 through the driving component 6. There is no need for workers to repeatedly remove the tray 4 and flip the tray 4 to dump the material, which saves time and effort, thereby improving the material collection efficiency.

[0034] At the same time, after the material in the tray 4 is completely dumped into the collection frame 7, the tray grip 52 drives the empty tray 4 to flip onto the second conveyor belt 3, and is transported to the next process under the conveyance of the second conveyor belt 3 for subsequent use. The setting of the second conveyor belt 3 realizes the automatic collection of the tray 4 with emptied materials, ensuring the continuity of the entire collection process.

[0035] Reference Figure 1 and Figure 2, the two opposite sides of the tray 4 are fixedly connected with a supporting edge 41, and the supporting edge 41 is in the shape of an outer flange. A limiting groove 8 is provided on the side wall of each tray grip 52 facing the bracket 1. When the first conveyor belt 2 drives the tray 4 to be transmitted to the vicinity of the tray grip 52, the supporting edge 41 of the tray 4 abuts against the inner bottom surface of the limiting groove 8. Under the guidance of the supporting edge 41 and the limiting groove 8, the tray 4 is slidably connected between the two opposite tray grips 52. The horizontal height of the bottom surface of the limiting groove 8 is on the same straight line as the horizontal height of the bottom surface of the supporting edge 41. A positioning plate 81 is fixedly connected to one end of each limiting groove 8 close to the bracket 1, and a pressure sensor 82 is fixedly installed on the positioning. The pressure sensor 82 is electrically connected to the rotating motor 61 through the control system.

[0036] When the first conveyor belt 2 drives the pallet 4 to be transmitted to the vicinity of the pallet grip 52, the two supporting edges 41 on the pallet 4 slide into the limiting groove 8 and abut against the limiting groove 8. At this time, the pallet 4 is mounted between the two pallet grips 52, thereby realizing the pallet grip 52 carrying the pallet 4. Under the transmission of the first conveyor belt 2, the pallet 4 continues to move in the limiting groove 8. When the pallet 4 abuts against the positioning plate 81, the pressure sensor 82 receives the pressure signal and controls the rotating motor 61 to start automatically. The rotating motor 61 drives the push plate to flip. Such a setting has a simple structure and improves the connection strength between the pallet 4 and the pallet grip 52 while realizing the detachable connection between the pallet 4 and the pallet grip 52, so that the pallet 4 will not easily separate from the pallet grip 52 due to external forces such as collision or vibration during the movement. At the same time, the setting of the positioning plate 81 limits the moving distance of the pallet 4 on the pallet grip 52, thereby fixing the flipping position of the pallet 4, ensuring the uniformity of the flipping position of each pallet 4, and ensuring that the material can be smoothly dumped into the collection frame 7.

[0037] Reference Figure 1 and Figure 2 In order to protect the driving assembly 6 inside the bracket 1, a shielding cover 9 is fixedly installed on the bracket 1. The shielding cover 9 completely covers the outer peripheral surface of the bracket 1, and the top plate of the shielding cover 9 is an inverted V-shaped plate.

[0038] The setting of the shielding cover 9 provides a sealed environment for the driving component 6 inside the bracket 1, thereby protecting the safety of the driving component 6 inside the bracket 1. At the same time, under the guidance effect of the top plate of the shielding cover 9, the material poured from the tray 4 can enter the collection frame 7 more smoothly and be collected, reducing the probability of material accumulation on the top of the shielding plate, thereby further improving the material collection efficiency.

[0039] The implementation principle of a pallet turning machine in the embodiment of the present application is as follows: the freeze-dried material is transferred to the pallet 4 of the first conveyor belt 2 by the transfer equipment; when the first conveyor belt 2 drives the pallet 4 to move near the support 1, the two supporting edges 41 on the pallet 4 slide into the limiting groove 8 and abut against the limiting groove 8; at this time, the pallet 4 is mounted between the two pallet grippers 52; under the transmission of the first conveyor belt 2, the pallet 4 continues to move in the limiting groove 8; when the pallet 4 abuts against the positioning plate 81, the pressure sensor 82 receives the pressure signal and controls the rotating motor 61 to start automatically; the rotating motor 61 drives The rotating shaft 62 rotates, and the rotation of the rotating shaft 62 drives the two fixed plates 51 to rotate synchronously. The rotation of the fixed plate 51 drives the tray grip 52 to rotate, and the tray grip 52 drives the tray 4 to automatically flip over. During the flipping process, the material on the tray 4 is poured into the collecting frame 7. After the material in the tray 4 is completely dumped into the collecting frame 7, the tray grip 52 drives the empty tray 4 to flip onto the second conveyor belt 3. The entire material collection process realizes the automatic flipping of the tray 4 through the driving component 6, and there is no need for workers to repeatedly remove the tray 4 and flip the tray 4 to dump the material, which saves time and effort, thereby improving the material collection efficiency.

[0040] Example 2

[0041] The difference between the embodiment of the present application and the embodiment 1 is that the two collecting frames 7 are detachably connected to the outer side wall of the bracket 1 .

[0042] Reference Figure 3 and Figure 4 , grooves 10 are provided on the side walls at both ends of the opposite sides of the shielding cover 9, and a connecting component 11 is arranged in the groove 10. Each collection frame 7 is detachably connected to the bracket 1 through the connecting component 11. The connecting component 11 includes a connecting shaft 111 rotatably connected to the groove 10, and a block 112 is fixedly connected to the outer wall of the connecting shaft 111. A protrusion 113 that is plugged into and matched with the groove 10 is fixedly installed on the side wall of the collection frame 7 close to the shielding cover 9. The protrusion 113 is provided with a slot 12 that is snap-fitted with the block 112. A torsion spring 114 is sleeved on the connecting shaft 111, and one end of the torsion spring 114 is fixedly connected to the inner wall of the groove 10, and the other end is fixedly connected to the connecting shaft 111. When the torsion spring 114 is in a natural state, the block 112 is snap-fitted into the inside of the slot 12.

[0043] The implementation principle of Example 2 is as follows: when the materials in the collection frame 7 are fully collected, the worker pulls the block 112 outward to disengage it from the slot 12. At this time, the protrusion 113 lacks the limit of the block 112, and the worker can easily remove the collection frame 7 from the bracket 1 for centralized processing of the materials. When the collection frame 7 needs to be installed, the worker pulls the block 112 outward to disengage the block 112 from the groove 10, and then inserts the protrusion 113 into the groove 10 and cancels the force on the block 112. Under the elastic force of the torsion spring 114, the torsion spring 114 drives the connecting shaft 111 to rotate, and the connecting shaft 111 drives the block 112 to engage in the slot 12. The detachable connection of the collection frame 7 on the outer wall of the bracket 1 is realized through the connecting component 11, and the disassembly and installation process is convenient and quick, which is convenient for the workers to operate and further improves the material collection efficiency.
