Description

Technical Field

[0001] This utility model belongs to the field of feeding mechanisms, specifically relating to a turnover box tilting feeding mechanism. Background Technology

[0002] In automated material handling systems, the core function of the turnover box tilting and unloading mechanism is to achieve smooth tilting and precise unloading of the material box. Traditional technology generally adopts a rotating shaft driven frame structure, that is, the frame carrying the box is tilted by a through rotating shaft.

[0003] However, the rotating shaft needs to pass through both sides of the frame, which causes an axial mechanical interference zone to be formed inside the frame. The housing cannot be placed in this area, forcing the housing to be installed off the rotation center, resulting in increased drive torque and reduced service life of the equipment.

[0004] Most unloading mechanisms use servo motors to drive the rotating frame. When the frame is rotated to the critical point of 90°, it will cause the frame to vibrate. Vibration is also likely to occur during start-up and shutdown, which will reduce the service life of the equipment. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a turnover box tilting and unloading mechanism, which effectively solves the problem that the rotating shaft needs to pass through both sides of the frame, resulting in an axial mechanical interference zone inside the frame. This area cannot be used to place the box, forcing the box installation position to deviate from the rotation center, resulting in increased driving torque. Some unloading mechanisms use servo motors to drive the rotating frame to rotate. When using servo motors, the frame will vibrate when it flips to the 90° critical point, and vibration is also likely to occur during start-up and shutdown, thereby reducing the service life of the equipment.

[0006] One embodiment of this utility model provides a turnover box tilting and unloading mechanism, including:

[0007] Mounting frame structure;

[0008] A rotating frame, which is rotatably mounted on the mounting frame structure;

[0009] A gear drive structure, wherein the gear drive structure is mounted on the mounting bracket structure;

[0010] A driven gear is mounted on the rotating frame and meshes with the drive end of the gear drive structure.

[0011] A lifting mechanism, which is mounted on the rotating frame;

[0012] The rotating frame is provided with a limiting area, which is used to limit the turnover box. The gear drive structure is used to drive the driven gear to rotate, and the lifting mechanism is used to push the turnover box into the limiting area.

[0013] This utility model discloses a tilting and unloading mechanism for turnover boxes. A rotating frame, a gear drive structure, and a lifting mechanism are mounted on an external unloading mechanism via a mounting bracket structure. The rotating frame receives the boxes to be unloaded. After receiving, the gear drive structure drives a driven gear to rotate, which in turn rotates the rotating frame and the unloaded box together. The lifting mechanism holds the unloaded box firmly against the limiting area of ​​the rotating frame, preventing the box from detaching during rotation. It can also fix boxes of different depths. Currently, existing tilting and unloading mechanisms all use a single rotating shaft to fix the rotating frame, and most of these shafts are electrically powered. In traditional machine-driven systems, the rotating frame, due to its weight, vibrates when tilting to unload material. This reduces the lifespan of the device. However, this invention uses gear drive, which significantly reduces vibration. Furthermore, instead of using a rotating shaft, the rotating frame rotates directly, bringing the center of gravity closer to the rotating frame's axis after the material is placed inside. This optimizes the torque and inertia required for unloading, while also reducing the space needed for rotation and unloading, further extending the device's lifespan.

[0014] In one embodiment, the mounting frame structure includes a fixing plate and mounting components;

[0015] The fixing plate is used for mounting on the unloading mechanism;

[0016] The mounting components are symmetrically and fixedly mounted on the fixing plate;

[0017] One of the mounting components is provided with a mounting housing, and the driven gear and the drive end of the gear drive structure are located inside the mounting housing.

[0018] In one embodiment, the gear drive structure includes a drive mechanism and a transmission gear.

[0019] In one embodiment, the drive mechanism is fixedly mounted on the mounting frame structure.

[0020] In one embodiment, the transmission gear is fixedly mounted on the rotating shaft of the drive mechanism, and the transmission gear meshes with the driven gear.

[0021] In one embodiment, the lifting mechanism includes a plurality of mounting plates, cylinders, and push plates.

[0022] In one embodiment, several of the mounting plates are disposed at the bottom of the rotating frame.

[0023] In one embodiment, each of the mounting plates is provided with a cylinder.

[0024] In one embodiment, the push plate is fixedly disposed on the output end of the cylinder, the output ends of each cylinder are in the same direction, and the cylinder is located below the rotating frame.

[0025] In one embodiment, one of the mounting members without the driven gear is rotatably connected to the rotating frame;

[0026] The rotating frame is provided with a box inlet.

[0027] The turnover box tilting and unloading mechanism provided by the above technical solution has the following beneficial effects:

[0028] 1. Currently, existing tilting and feeding mechanisms all use a rotating shaft to fix the rotating frame, and most of the rotating shafts are driven by motors. When the rotating frame tilts and feeds, due to the heavy weight of the box and the rotating frame, the rotating frame shakes due to gravity when it flips over to the top of the feed inlet, which reduces the service life of the device. However, this utility model uses gear drive, which greatly reduces the occurrence of shaking.

[0029] 2. The rotating frame of this utility model does not use a rotating shaft to drive the rotation, but directly rotates the entire rotating frame (without being blocked by the rotating shaft, so that the unloading box can be placed closer to the rotation center axis of the rotating frame). After the unloading box is placed in the rotating frame, the overall center of gravity can be closer to the rotation center axis of the rotating frame, which optimizes the torque and inertia required for rotation during unloading. At the same time, the space required for rotating and unloading is smaller, which also greatly improves the service life of the device.

[0030] 3. The rotating frame, gear drive structure, and lifting mechanism are installed on the external unloading mechanism through the mounting frame structure. The rotating frame is used to receive the boxes to be unloaded. After receiving, the gear drive structure drives the driven gear to rotate. The rotation of the driven gear drives the rotating frame and the unloaded box to rotate together. The lifting mechanism is used to press the unloaded box tightly against the limiting area of ​​the rotating frame, so that the box will not detach from the rotating frame during rotation. It can also fix boxes of different depths. Attached Figure Description

[0052] Combination Figures 1 to 4 As shown, one embodiment of this utility model provides a turnover box tilting and unloading mechanism, including:

[0053] Mounting frame structure 100;

[0054] A rotating frame 200 is rotatably mounted on the mounting frame structure 100;

[0055] A gear drive structure 300 is mounted on the mounting bracket structure 100;

[0056] Driven gear 400 is mounted on the rotating frame 200 and meshes with the drive end of the gear drive structure 300.

[0057] A lifting mechanism 500 is mounted on the rotating frame 200;

[0058] The rotating frame 200 is provided with a limiting area 600, which is used to limit the turnover box. The gear drive structure 300 is used to drive the driven gear 400 to rotate. The lifting mechanism 500 is used to push the turnover box into the limiting area 600.

[0059] This utility model discloses a tilting and unloading mechanism for turnover boxes. A rotating frame 200, a gear drive structure 300, and a lifting mechanism 500 are mounted on an external unloading mechanism via a mounting frame structure 100. The rotating frame 200 receives the boxes 700 to be unloaded. After receiving, the gear drive structure 300 drives the driven gear 400 to rotate. The rotation of the driven gear 400 causes the rotating frame 200 and the unloaded box 700 to rotate together. The lifting mechanism 500 presses the unloaded box 700 against the limiting area 600 of the rotating frame 200, preventing the box 700 from detaching from the rotating frame 200 during rotation. It can also fix boxes 700 of different depths. Currently, existing tilting and unloading mechanisms all use a single rotating shaft to fix the rotating frame 200. 0. In most cases, the rotating shaft is driven by a motor. When the rotating frame 200 tilts to unload material, the weight of the box 700 plus the rotating frame 200 is relatively heavy. When the rotating frame 200 is flipped above the feed inlet, the rotating frame 200 vibrates due to gravity, reducing the service life of the device. However, this utility model uses gear drive, which greatly reduces the occurrence of vibration. Moreover, the rotating frame 200 of this utility model does not use a rotating shaft to drive the rotation, but directly rotates the entire rotating frame 200. This makes the center of gravity of the box 700 after it is placed into the rotating frame 200 closer to the rotation center axis of the rotating frame 200. This optimizes the torque and inertia required for rotation during unloading, and at the same time, the space required for rotation and unloading is smaller, which also greatly improves the service life of the device.

[0060] In one embodiment, the mounting frame structure 100 includes a fixing plate 110 and a mounting member 120;

[0061] The fixing plate 110 is used to be installed on the unloading mechanism;

[0062] The mounting components 120 are symmetrically and fixedly disposed on the fixing plate 110;

[0063] One of the mounting components 120 is provided with a mounting housing 121, and the driven gear 400 and the drive end of the gear drive structure 300 are located inside the mounting housing 121.

[0064] In this embodiment, the fixing plate 110 is used to install the rotating frame 200, the gear drive structure 300 and the lifting mechanism 500 on the external unloading mechanism. The rotating frame 200 is rotatably installed between two mounting parts 120. The gear drive structure 300 drives the driven gear 400 to rotate, thereby driving the rotating frame 200 to rotate.

[0065] It should be noted that existing tilting and unloading mechanisms all use a single rotating shaft to fix the rotating frame 200, and most of these rotating shafts are driven by a motor. When the rotating frame 200 tilts and unloads, the weight of the box 700 plus the rotating frame 200 is relatively heavy. When the rotating frame 200 is tilted above the feed inlet, the rotating frame 200 vibrates due to gravity, reducing the service life of the device. However, this invention uses gear drive, which greatly reduces the vibration. Moreover, this invention does not use a rotating shaft to drive the rotation of the rotating frame 200, but directly rotates the entire rotating frame 200. This makes the center of gravity of the box 700 after it is placed into the rotating frame 200 closer to the rotation center axis of the rotating frame 200, thus optimizing the torque and inertia required for rotation during unloading. At the same time, the space required for rotation and unloading is smaller, which also greatly improves the service life of the device.

[0066] In one embodiment, the gear drive structure 300 includes a drive mechanism 310 and a transmission gear 320;

[0067] The drive mechanism 310 is fixedly mounted on the mounting frame structure 100;

[0068] The transmission gear 320 is fixedly mounted on the rotating shaft of the drive mechanism 310, and the transmission gear 320 meshes with the driven gear 400.

[0069] In this embodiment, the drive mechanism 310 drives the transmission gear 320 to rotate. Since the transmission gear 320 and the driven gear 400 mesh, the rotation of the transmission gear 320 drives the driven gear 400 to rotate, and the rotation of the driven gear 400 drives the rotating frame 200 to rotate.

[0070] In one embodiment, the lifting mechanism 500 includes a plurality of mounting plates 510, cylinders 520 and push plates 530;

[0071] Several mounting plates 510 are disposed at the bottom of the rotating frame 200;

[0072] Each of the mounting plates 510 is provided with a cylinder 520;

[0073] The push plate 530 is fixedly mounted on the output end of the cylinder 520. The output ends of each cylinder 520 are in the same direction, and the cylinder 520 is located below the rotating frame 200.

[0074] One of the mounting pieces 120, which does not have the driven gear 400 installed, is rotatably connected to the rotating frame 200;

[0075] The rotating frame 200 is provided with a box inlet 210.

[0076] In this embodiment, the rotating frame 200, gear drive structure 300, and lifting mechanism 500 are mounted on the external unloading mechanism via the mounting frame structure 100. The rotating frame 200 is used to receive the box 700 to be unloaded. After receiving, the gear drive structure 300 drives the driven gear 400 to rotate. The rotation of the driven gear 400 drives the rotating frame 200 and the unloaded box 700 to rotate together. The cylinder 520 and push plate 530 are used to press the unloaded box 700 against the limiting area 600 of the rotating frame 200, so that the box 700 will not detach from the rotating frame 200 during rotation. It can also fix boxes 700 of different depths. The mounting plate 510 is used to mount the cylinder 520. Generally, when the box 700 is placed, a positioning photoelectric sensor is used to detect the placement position of the box 700. After detecting that the box 700 is placed in the designated position, the cylinder 520 is activated to press the box 700 against the frame.

[0077] It should be noted that the rotating frame 200 is symmetrically equipped with limiting members 230, which are L-shaped. The two limiting members 230 form a limiting area 600, thereby limiting the housing 700 and preventing the housing 700 from falling out of the device during rotation. The rotating frame 200 is also equipped with a limiting rod 220, which limits the pushing distance of the housing 700 after it is pushed into the rotating frame 200 (here, "pushing" means that most of the housing 700 is transported into the rotating frame 200 by a pusher). Because the above structure is quite common, it is only mentioned in the instruction manual, but is explained here.

[0078] Furthermore, Figure 1 The rotation direction of the rotating frame 200 is indicated here for illustrative purposes.

[0079] Furthermore, gear transmission is more stable than direct motor drive because multiple teeth contact each other when gears mesh, like multiple people lifting a heavy object together, the impact force is dispersed, avoiding single-point overload. The gear meshing process produces slight elastic deformation, similar to the effect of a spring, which can absorb the impact of sudden start and stop. The gear set reduces the motor speed through the reduction ratio, like a car shifting to a low gear to climb a hill, resulting in smoother power output and less susceptibility to sudden load changes.

[0080] The working principle of this utility model:

[0081] The rotating frame 200, gear drive structure 300, and lifting mechanism 500 are mounted on the external unloading mechanism via the mounting frame structure 100. The rotating frame 200 is used to receive the box 700 to be unloaded. After receiving, the gear drive structure 300 drives the driven gear 400 to rotate. The rotation of the driven gear 400 drives the rotating frame 200 and the unloaded box 700 to rotate together. The lifting mechanism 500 is used to press the unloaded box 700 against the limiting area 600 of the rotating frame 200, so that the box 700 will not detach from the rotating frame 200 during rotation. It can also fix boxes 700 of different depths. The rotating frame 200 rotates to unload, and then resets after unloading, thus completing the unloading action.

[0082] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made using the paper parts and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
