Description

Technical Field

[0001] This utility model relates to the field of pallet loading and unloading technology, specifically to a pallet loading and unloading device that facilitates pallet placement. Background Technology

[0002] In modern industrial production systems, the loading of semi-finished products or blanks is one of the steps in the production line. To ensure that the loading mechanism can grasp the workpieces with high precision and speed and complete subsequent assembly or processing tasks, the workpieces need to be pre-sorted and stored in an orderly manner on trays before loading, thus providing a reliable material basis for automated loading.

[0003] Currently, the pallet loading and unloading process commonly used in the industry is still based on the traditional model, which includes the following steps: First, operators manually remove empty pallets from the empty pallet hopper and move them to the designated loading station; then, using industrial robots or manual operation, the workpieces to be processed are placed into the preset positions within the pallet until it is completely full; finally, the full pallets are transferred manually or with the aid of simple handling tools to the storage bin for stacking to save space and facilitate centralized management. When the production line issues a loading request, operators must remove the pallets from the storage bin and transfer them to the loading station for the loading mechanism to pick up the workpieces for further processing.

[0004] Although the above process achieves the orderly flow and basic management of workpieces, it relies too much on manual operation, which is not only inefficient and unable to meet the needs of large-scale, high-paced production, but also labor-intensive, increasing operator fatigue and the risk of work-related injuries.

[0005] In view of the shortcomings of the existing technology, it is necessary to develop a pallet loading and unloading device that is easy to use and can automatically complete pallet loading, unloading and storage. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a pallet loading and unloading device that facilitates tray placement. At least the technical problem it can solve is: how to automatically load, unload, and store pallets, thereby improving production efficiency and reducing labor intensity.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tray loading and unloading device for easy tray placement, comprising:

[0010] The machine frame has a tray-loading station.

[0011] Both the input and output mechanisms are mounted on the frame and are used for conveying pallets;

[0012] The turnover mechanism, empty disk compartment, and storage compartment are all located on the rack. The output end of the input mechanism and the input end of the output mechanism are both positioned opposite to the turnover mechanism. The empty disk compartment and storage compartment are both located above the turnover mechanism and are positioned opposite to the input mechanism and the output mechanism, respectively.

[0013] The pallet loading and unloading device, which facilitates pallet placement, includes a storage state, a pallet placement state, and a loading state. In the storage state, the turnover mechanism is used to receive empty pallets from the output end of the input mechanism and stack them into the empty pallet bin. In the pallet placement state, the turnover mechanism is used to transfer empty pallets in the empty pallet bin one by one to the pallet placement station, and to transfer pallets filled with materials at the pallet placement station and stack them into the storage bin. In the loading state, the turnover mechanism is used to transfer pallets in the storage bin one by one to the output mechanism.

[0014] Further configuration: the aforementioned empty pallet hopper, pallet loading station and storage hopper are arranged sequentially along the X-axis direction, and each of the empty pallet hopper and storage hopper is equipped with at least one first material blocking mechanism to prevent the pallet from moving out.

[0015] The turnover mechanism includes a conveying drive assembly, a turnover frame, and a lifting drive assembly. The turnover frame is used to carry a single pallet. The conveying drive assembly is located on the frame and is connected to the turnover frame in a transmission manner. The lifting drive assembly is located on the turnover frame. The conveying drive assembly is used to drive the turnover frame and the lifting drive assembly to move along the X-axis direction so that the turnover frame and the lifting drive assembly are positioned relative to the empty pallet bin or storage bin, or so that the turnover frame is located at the pallet placement station.

[0016] In a further configuration, both the aforementioned input and output mechanisms include a drive shaft, at least one first driven shaft, two second driven shafts, a conveyor belt, a conveyor belt drive, a telescopic drive, and a movable frame. The conveyor belt is sleeved on the outside of the pulleys of the drive shaft, the first driven shaft, and the second driven shaft. The conveyor belt drive is mounted on the frame and is drivenly connected to the drive shaft. The telescopic drive is mounted on the frame and is drivenly connected to the movable frame. The drive shaft and the first driven shaft are rotatably mounted on the frame, and the two second driven shafts are rotatably mounted on the movable frame. Each of the drive shaft, the first driven shaft, and the second driven shaft is equipped with a pulley.

[0017] The conveyor belt drive is used to drive the drive shaft to rotate, thereby driving the conveyor belt to rotate and transport the pallets on the conveyor belt; the telescopic drive is used to drive the movable frame to move toward or away from the turnover mechanism, so as to extend part of the conveyor belt into or completely move it out between the turnover mechanism and the empty pallet bin or storage bin.

[0018] Furthermore, the aforementioned empty pallet compartment facing the input mechanism and the storage compartment facing the output mechanism are both provided with inlets and outlets for pallet input or output;

[0019] The pallet loading and unloading device that facilitates pallet placement also includes two second-stage blocking mechanisms. These two mechanisms are located at the inlet and outlet of the empty pallet compartment and the storage compartment, respectively, and are used to block the pallet input and output inlet and outlet.

[0020] In a further configuration, the aforementioned second baffle mechanism includes at least one baffle and a baffle drive. The baffle is rotatably located at the inlet or outlet of the empty tray or storage bin, and the baffle drive is installed on the outside of the empty tray or storage bin and is connected to the baffle in a transmission manner. The baffle drive is used to drive the baffle to rotate away from or towards the inlet or outlet to open or close the inlet or outlet.

[0021] Further, the pallet loading and unloading device for easy tray placement also includes two third-stage blocking mechanisms. The two third-stage blocking mechanisms are located on the frame and are respectively located in front of the two inlets and outlets. The two third-stage blocking mechanisms are used to block the pallet from moving toward or out of the turnover mechanism.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the tray loading and unloading device provided by this utility model has the following advantages:

[0024] The pallet loading and unloading device provided by this utility model has three highly coordinated working states: storage state, pallet stacking state, and loading state. In the storage state, the input mechanism sends empty pallets one by one or stack by stack to the turnover mechanism. The turnover mechanism receives the empty pallets from the output end of the input mechanism and stacks them into the empty pallet bin. This process realizes the automatic storage of empty pallets. In the pallet stacking state, the input mechanism stops sending empty pallets, and at the same time, the turnover mechanism transfers the empty pallets in the empty pallet bin one by one to the pallet stacking station. The existing pallet stacking mechanism places the workpieces into the preset positions in the pallets of the pallet stacking station until the pallet is completely full. Then, the turnover mechanism transfers the full pallet to the storage bin for storage. This process realizes the automatic loading of empty pallets and the automatic storage of full pallets. In the loading state, the turnover mechanism transfers the pallets in the storage bin one by one to the output mechanism. Subsequently, the output mechanism transports the full pallet to the loading station, where the existing loading mechanism picks up the workpieces for subsequent assembly or processing. This process realizes the automatic loading of full pallets. As can be seen, by flexibly switching between different working states, this utility model can automatically complete the loading, unloading, and storage of pallets, effectively reducing the degree of manual intervention, thereby greatly improving overall production efficiency and significantly reducing labor intensity.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] This utility model provides a pallet loading and unloading device that facilitates tray placement, which solves the problem of how to automatically load, unload, and store pallets 7, thereby improving production efficiency and reducing labor intensity.

[0039] See Figure 1 As shown, Figure 1 The figure shows a perspective view of a pallet loading and unloading device for easy pallet placement in the embodiment. The pallet loading and unloading device includes a frame 1, an input mechanism 2, an output mechanism 3, a turnover mechanism 4, an empty pallet compartment 5, and a storage compartment 6.

[0040] The frame 1 is equipped with a tray-sloshing station 11.

[0041] Both the input mechanism 2 and the output mechanism 3 are mounted on the frame 1 and are used to transport the pallet 7.

[0042] The turnover mechanism 4, empty disk compartment 5, and storage compartment 6 are all mounted on the rack 1. The output end of the input mechanism 2 and the input end of the output mechanism 3 are both opposite to the turnover mechanism 4. The empty disk compartment 5 and the storage compartment 6 are both located above the turnover mechanism 4 and are opposite to the input mechanism 2 and the output mechanism 3, respectively.

[0043] The pallet loading and unloading device, which facilitates pallet placement, includes a storage state, a pallet placement state, and a loading state. In the storage state, the turnover mechanism 4 is used to receive empty pallets 7 from the output end of the input mechanism 2 and stack them into the empty pallet bin 5. In the pallet placement state, the turnover mechanism 4 is used to transfer empty pallets 7 from the empty pallet bin 5 to the pallet placement station 11 one by one, and to transfer and stack pallets 7 filled with materials on the pallet placement station 11 into the storage bin 6. In the loading state, the turnover mechanism 4 is used to transfer pallets 7 from the storage bin 6 to the output mechanism 3 one by one.

[0044] The pallet loading and unloading device of the above technical solution has three highly coordinated working states: storage state, pallet stacking state, and loading state. In the storage state, the input mechanism 2 sends empty pallets 7 one by one or stack by stack to the turnover mechanism 4. The turnover mechanism 4 receives the empty pallets 7 from the output end of the input mechanism 2 and stacks them into the empty pallet bin 5. This process realizes the automatic storage of empty pallets 7. In the pallet stacking state, the input mechanism 2 stops conveying empty pallets 7, and at the same time, the turnover mechanism 4 transfers the empty pallets 7 in the empty pallet bin 5 one by one to the pallet stacking station 11. The existing pallet stacking mechanism places the workpieces into the preset positions of the pallets 7 in the pallet stacking station 11 until the pallet 7 is completely full. Then, the turnover mechanism 4 transfers the full pallet 7 to the storage bin 6 for storage. This process realizes the automatic loading of empty pallets 7 and the automatic storage of full pallets 7. During the loading phase, the turnover mechanism 4 transfers the pallets 7 in the storage compartment 6 one by one to the output mechanism 3. Subsequently, the output mechanism 3 transports the pallets 7 filled with materials to the loading station, where the existing loading mechanism picks up the workpieces for subsequent assembly or processing. This process achieves automatic loading of the full pallets 7. It can be seen that this utility model has three highly coordinated working states: storage state, tray placement state, and loading state. By flexibly switching between different working states, it can automatically complete the loading, unloading, and storage of pallets 7, effectively reducing the degree of manual intervention, thereby greatly improving overall production efficiency and significantly reducing labor intensity.

[0045] See Figure 1 and Figure 2 As shown, Figure 2This is a schematic diagram of the empty tray hopper, input mechanism, and turnover mechanism in one embodiment. In one implementation of the turnover mechanism 4, the turnover mechanism 4 includes a conveying drive assembly 41, a turnover frame 42, and a lifting drive assembly 43. The turnover frame 42 is used to carry a single tray 7. The conveying drive assembly 41 is mounted on the frame 1 by means of screwing or welding and is connected to the turnover frame 42 in a driving manner. The lifting drive assembly 43 is mounted on the turnover frame 42 by means of screwing or welding. The empty tray hopper 5, the tray placement station 11, and the storage compartment 6 are arranged sequentially along the X-axis. The empty tray hopper 5 and the storage compartment 6 are each equipped with at least one first blocking mechanism 51 for preventing the tray 7 from moving out. The conveying drive assembly 41 is used to drive the turnover frame 42 and the lifting drive assembly 43 to move along the X-axis, so that the turnover frame 42 and the lifting drive assembly 43 are positioned opposite the empty tray hopper 5 or the storage compartment 6, or so that the turnover frame 42 is located at the tray placement station 11. Thus, in the storage state, the conveying drive assembly 41 drives the turnover frame 42 and the lifting drive assembly 43 to move together to the position opposite to the empty tray 5, and the lifting drive assembly 43 receives the empty tray 7 on the output end of the input mechanism 2; then, the first blocking mechanism 51 releases the obstruction of the tray 7 in the empty tray 5, and at the same time, the lifting drive assembly 43 stacks the empty tray 7 into the empty tray 5, realizing the automatic storage of the empty tray 7; finally, the first blocking mechanism 51 restores the obstruction of the tray 7 in the empty tray 5 to prevent the empty tray 7 from accidentally falling out of the empty tray 5. In the tray-stacking state, the conveyor drive assembly 41 first drives the turnover rack 42 and the lifting drive assembly 43 to move together to a position opposite to the empty tray bin 5; then, the first stop mechanism 51 releases the obstruction of the tray 7 in the empty tray bin 5, while the lifting drive assembly 43 moves the bottommost tray 7 out of the empty tray bin 5; then, the first stop mechanism 51 restores the obstruction of the tray 7 in the empty tray bin 5 to prevent other trays 7 in the empty tray bin 5 from also being moved out of the empty tray bin 5, while the lifting drive assembly 43 places the tray 7 on the turnover rack 42; then the conveyor drive assembly 41 drives... The movable turnover rack 42 and the lifting drive assembly 43 move together to the tray loading station 11, realizing the automatic loading of empty trays 7; after the tray loading is completed, the conveying drive assembly 41 drives the turnover rack 42 and the lifting drive assembly 43 to move together to the position opposite to the storage bin 6; then, the first blocking mechanism 51 releases the obstruction of the trays 7 in the storage bin 6, and at the same time, the lifting drive assembly 43 stacks the trays 7 on the turnover rack 42 into the storage bin 6 for storage, realizing the automatic storage of full trays 7; finally, the first blocking mechanism 51 restores the obstruction of the trays 7 in the storage bin 6.During the loading process, the conveying drive assembly 41 drives the turnover frame 42 and the lifting drive assembly 43 to move together to a position opposite to the storage bin 6. Subsequently, the first blocking mechanism 51 releases the obstruction of the pallet 7 in the storage bin 6, while the lifting drive assembly 43 moves the bottom pallet 7 out of the storage bin 6. Finally, the first blocking mechanism 51 restores the obstruction of the pallet 7 in the storage bin 6, while the lifting drive assembly 43 places the pallet 7 filled with material onto the output mechanism 3, which then transports it to the loading station, thus realizing automatic loading of the full pallet 7.

[0046] The aforementioned turnover frame 42 can be slidably connected to the frame 1, which ensures the stability of the turnover frame 42 and the lifting drive assembly 43 during the displacement process along the X-axis.

[0047] The aforementioned conveying drive assembly 41 can use existing linear drive mechanisms such as servo motor-lead screw and nut linear modules, and its output end is connected to the turnover frame 42 by screwing or welding. The aforementioned first blocking mechanism 51 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and the first blocking mechanism 51 is positioned opposite to the bottommost pallet 7 in the empty pallet compartment 5 or storage compartment 6. In this way, the output end of the first blocking mechanism 51 extends into the empty pallet compartment 5 or storage compartment 6 and abuts against the bottommost pallet 7, thereby fixing the bottommost pallet 7 and preventing the pallet 7 in the empty pallet compartment 5 or storage compartment 6 from moving out.

[0048] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 This is a front view of the empty tray, input mechanism, and turnover mechanism in one embodiment. In one implementation of the input mechanism 2 and output mechanism 3, both the input mechanism 2 and output mechanism 3 include a drive shaft 21, at least one first driven shaft 22, two second driven shafts 23, a conveyor belt 24, a conveyor belt drive component 25, a telescopic drive component 26, and a movable frame 27. The conveyor belt drive component 25 is mounted on the frame 1 by screwing or welding and is drive-connected to the drive shaft 21. The telescopic drive component 26 is mounted on the frame 1 by screwing or welding and is drive-connected to the movable frame 27. The drive shaft 21 and the first driven shaft 22 are rotatably connected to the frame 1. The two second driven shafts 23 are rotatably connected to the movable frame 27. Pulleys 28 are mounted on the drive shaft 21, the first driven shaft 22, and the second driven shaft 23. The conveyor belt 24 is sleeved on the outside of the pulleys 28 of the drive shaft 21, the first driven shaft 22, and the second driven shaft 23. The conveyor belt drive 25 drives the drive shaft 21 to rotate, thereby driving the conveyor belt 24 to rotate, so as to transport the pallet 7 on the conveyor belt 24; the telescopic drive 26 drives the movable frame 27 to move towards or away from the turnover mechanism 4, so as to extend part of the conveyor belt 24 between the turnover mechanism 4 and the empty pallet hopper 5 or storage hopper 6 (e.g., Figure 2(as shown), or completely remove the conveyor belt 24 from between the turnover mechanism 4 and the empty tray 5 or storage tray 6 (as shown). Figure 3 (As shown). It can be seen that the input mechanism 2 can drive the movable frame 27 and the two second driven shafts 23 to move through the telescopic drive member 26, so that the conveyor belt 24 can be flexibly extended between the turnover mechanism 4 and the empty pallet hopper 5 or storage hopper 6, and dock with the empty pallet hopper 5 or storage hopper 6 to ensure that the pallet 7 can be smoothly transferred between different components. Specifically, when the conveyor belt 24 is partially extended between the turnover mechanism 4 and the empty pallet hopper 5, the conveyor belt drive member 25 drives the conveyor belt 24 to rotate, so that the pallet 7 on the conveyor belt 24 can be directly and smoothly input between the turnover mechanism 4 and the empty pallet hopper 5, so that the turnover mechanism 4 can stack the pallet 7 on the conveyor belt 24 into the empty pallet hopper 5; when the conveyor belt 24 is partially extended between the turnover mechanism 4 and the storage hopper 6, the turnover mechanism 4 can place the pallet 7 in the storage hopper 6 directly on the conveyor belt 24 located between the turnover mechanism 4 and the storage hopper 6, and then the conveyor belt drive member 25 drives the conveyor belt 24 to rotate, so that the pallet 7 can be smoothly sent out.

[0049] The aforementioned conveyor belt drive component 25 can use existing rotary motors or rotary drive mechanisms, with its output end connected to the drive shaft 21 via a belt assembly or gear set. The aforementioned telescopic drive component 26 can use existing telescopic cylinders or telescopic poles or linear drive mechanisms, with its output end connected to the movable frame 27 via screwing or welding.

[0050] See Figure 2 and Figure 3 As shown, in one embodiment of the lifting drive assembly 43, the lifting drive assembly 43 includes a lifting frame 431 and a lifting frame drive component 432. The lifting frame drive component 432 is mounted on the turnover frame 42 by means of screwing or welding, and is connected to the lifting frame 431 in a transmission manner. The lifting frame drive component 432 is used to drive the lifting frame 431 to move up and down. In this way, when the lifting frame 431 rises and passes through the bearing surface 421 of the movable frame 27 or the turnover frame 42, it can drive the pallets 7 on the movable frame 27 or the turnover frame 42 to rise and enter the empty pallet compartment 5 or the storage compartment 6, thereby realizing the stacking of the pallets 7. When the lifting frame 431 descends to below the bearing surface 421 of the turnover frame 42, the pallets 7 on the lifting frame 431 can be placed on the turnover frame 42.

[0051] The aforementioned lifting frame drive component 432 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the lifting frame 431 by means of screwing or welding.

[0052] See Figure 1As shown, based on the above embodiment, the empty pallet hopper 5 facing the input mechanism 2 and the storage hopper 6 facing the output mechanism 3 both have inlet / outlet 52 for the input or output of the pallet 7. This pallet loading / unloading device, which facilitates pallet placement, also includes two second blocking mechanisms 8. The two second blocking mechanisms 8 are respectively installed at the inlet / outlet 52 of the empty pallet hopper 5 and the storage hopper 6, and are used to block the inlet / outlet 52 of the pallet 7. Thus, when the pallet 7 is input into the empty pallet hopper 5 or output into the storage hopper 6 along with the conveyor belt 24, the second blocking mechanism 8 controls the inlet / outlet 52 to open, facilitating the entry and exit of the pallet 7 into the empty pallet hopper 5 or the storage hopper 6; and after the pallet 7 is input or output, the second blocking mechanism 8 controls the inlet / outlet 52 to close, effectively preventing the pallet 7 from accidentally sliding out of the empty pallet hopper 5 or the storage hopper 6 when no movement is required.

[0053] See Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the second blocking mechanism 8, the second blocking mechanism 8 includes at least one baffle 81 and a baffle drive member 82. The baffle 81 is rotatably connected to the inlet / outlet 52 of the empty tray hopper 5 or storage hopper 6. The baffle drive member 82 is installed on the outside of the empty tray hopper 5 or storage hopper 6 by means of screwing or welding, and is drively connected to the baffle 81. The baffle drive member 82 is used to drive the baffle 81 to rotate away from or towards the inlet / outlet 52 to open or close the inlet / outlet 52. In this way, the opening and closing of the inlet / outlet 52 is realized by driving the baffle 81 to rotate through the baffle drive member 82, thereby realizing the opening and closing of the empty tray hopper 5 or storage hopper 6. This structure is simple and reliable, easy to operate, and can quickly respond to control signals to achieve effective control of the entry and exit of the tray 7.

[0054] The aforementioned baffle drive component 82 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is rotatably connected to the baffle 81.

[0055] See Figure 1 As shown, based on any of the above embodiments, the pallet loading and unloading device for easy tray placement also includes two third blocking mechanisms 9. The third blocking mechanisms 9 are installed on the frame 1 by screwing or welding. The two third blocking mechanisms 9 are respectively configured to correspond to the input mechanism 2 and the output mechanism 3, and are used to prevent the pallet 7 from moving towards the turnover mechanism 4 or out of the output mechanism 3. Thus, the design of the third blocking mechanism 9 corresponding to the input mechanism 2 effectively prevents the input mechanism 2 from inputting the next empty pallet 7 between the turnover mechanism 4 and the empty pallet 5 before the turnover mechanism 4 has stacked the previous empty pallet 7 into the empty pallet bin 5, thus affecting the stacking and storage operation of the previous empty pallet 7; while the design of the third blocking mechanism 9 corresponding to the output mechanism 3 effectively prevents the output mechanism 3 from outputting the pallet 7 before the production line issues a loading request, thus affecting subsequent operations.

[0056] The aforementioned third material blocking mechanism 9 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles. Its output end extends into the input mechanism 2 or the output mechanism 3, which can prevent the tray 7 from moving with the input mechanism 2 or the output mechanism 3.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
