Description

Technical Field

[0001] This invention relates to the field of ton bag unloading technology, specifically a non-destructive unloading mechanism for ton bags. Background Technology

[0002] A ton bag (also known as a bulk container, jumbo bag, or space bag) is a large, flexible transport packaging container made of flexible materials such as polypropylene, with a load capacity of about 1 ton. It requires the use of lifting equipment and is specifically designed for the containerized storage and transportation of bulk powdery, granular, or lumpy materials. Currently, to improve unloading speed, factories commonly use ton bags to directly lower the material into the crusher, avoiding spillage and subsequent cleanup. Some factories use overhead cranes or forklifts to lift or scoop up the ton bags, then manually cut them open with knives to release the material. However, the spillage is irregular and unsafe, potentially injuring nearby workers. Furthermore, both methods prevent the ton bags from being reused and require improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a non-destructive unloading mechanism for ton bags. When unloading materials from ton bags, the operator only needs to drive a forklift to place the ton bag on the device's carrying platform. Then, the device automatically flips and tilts the materials in the ton bag to guide the unloading through the cooperation of clamping and tilting elements. The operation is convenient and safe, does not damage the structure of the ton bag, and allows the ton bag to be reused, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a ton bag non-destructive unloading mechanism, including a base, a support frame on the upper side of the base, and further including a self-turning component and a platform self-clamping component;

[0005] Self-flipping assembly: It includes a rotating shaft and a flipping platform. The rotating shaft is longitudinally and symmetrically connected to the upper end of the support frame through a bearing. A flipping platform is provided between the rotating shafts.

[0006] Platform self-clamping component: It is located at the left end of the tilting platform. When unloading materials from the ton bag, the operator only needs to drive a forklift to place the ton bag on the device's carrying platform. Then, the device automatically tilts and guides the unloading of the material in the ton bag by cooperating with the clamping element and the tilting element. The operation is convenient and safe, and will not damage the structure of the ton bag, so that the ton bag can be reused.

[0007] Furthermore, a controller is provided on the front side of the support frame, and the input end of the controller is electrically connected to an external power source, which facilitates the control of the operation of electrical components in the device.

[0008] Furthermore, the self-reversing assembly also includes a second rotating shaft and an electro-hydraulic actuator. The second rotating shaft is longitudinally and symmetrically connected to the right side of the reversing platform and the right end of the base through a second bearing. An electro-hydraulic actuator is provided between each of two vertically adjacent second rotating shafts. The input end of the electro-hydraulic actuator is electrically connected to the output end of the controller to provide power for the reversing and unloading of the ton bag in the ton bag non-destructive unloading mechanism.

[0009] Furthermore, the platform self-clamping component includes a rotating shaft three, clamping claws, and a linkage shaft. The rotating shaft three is vertically and equidistantly rotatably connected to the front and rear ends of the left side of the tilting platform through bearing three. Clamping claws are provided on the outer arc surface of the rotating shaft three. A linkage shaft is rotatably connected between vertically adjacent clamping claws through bearing four to radially limit the ton bag in the ton bag non-destructive unloading mechanism.

[0010] Furthermore, the platform self-clamping assembly also includes a fixed base, a rotating shaft four, and an electro-hydraulic actuator two. The fixed base is respectively located on the left end of the front and rear sides of the tilting platform. The rotating shaft four is rotatably connected to the inside of the fixed base through a bearing five. An electro-hydraulic actuator two is provided between the rotating shaft four and the horizontally adjacent linkage shaft. The input end of the electro-hydraulic actuator two is electrically connected to the output end of the controller to provide power for the unloading and fixing of the ton bag in the ton bag non-destructive unloading mechanism.

[0011] Furthermore, the clamping claws at the front left side and the rear left side of the flipping platform are vertically staggered to each other, which increases the vertical clamping coverage of the clamping claws on the ton bag in the non-destructive dumping mechanism.

[0012] Furthermore, the outer arc surface of the clamping claw is provided with uniformly distributed reinforcing ribs to improve the structural strength of the clamping claw in the ton bag non-destructive unloading mechanism.

[0013] Furthermore, the upper right wall of the flipping platform is provided with two vertically distributed connecting seats, and an electro-hydraulic actuator three is provided between the connecting seats. The input end of the electro-hydraulic actuator three is electrically connected to the output end of the controller, and the telescopic end of the electro-hydraulic actuator three is provided with a top rod, which vertically limits the bottom wall of the ton bag in the ton bag non-destructive dumping mechanism within the flipping platform.

[0014] Furthermore, the bottom of the base is provided with evenly distributed mounting holes to facilitate the positioning and fixing of the ton bag non-destructive material pouring mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This non-destructive material unloading mechanism for ton bags has the following advantages:

[0016] 1. When using the non-destructive unloading mechanism for ton bags of the same size, the operator drives a forklift to place the ton bag on the device's carrying platform. The device automatically clamps and fixes the ton bag inside radially through the clamping element. At the same time, the flipping element flips the ton bag to unload the material, and the shell of the flipping platform moves and limits the material to tilt and unload. The various components work together to automatically flip, tilt and guide the material in the ton bag for unloading without the need for operator intervention. The operation is convenient and safe. This process does not damage the structure of the ton bag, allowing the ton bag to be reused.

[0017] 2. When using the non-destructive unloading mechanism to unload ton bags of the same size, the electric components can automatically limit the vertical movement of the ton bags inside the device, preventing them from separating and falling off from the device during subsequent unloading.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-5This embodiment provides a technical solution: a ton bag non-destructive unloading mechanism, including a base 1, a support frame 2 on the upper side of the base 1, a controller 3 on the front side of the support frame 2, the input end of the controller 3 being electrically connected to an external power supply, and the controller 3 being fixed to the operating position around the device by screws, instead of being fixed to the support frame 2, so that the operator can operate and control the device remotely relative to the device, and also includes a self-flipping component 4 and a platform self-clamping component 5;

[0026] Self-flipping assembly 4: It includes a rotating shaft 41 and a flipping platform 42. The rotating shaft 41 is longitudinally and symmetrically connected to the upper end of the support frame 2 through a bearing. A flipping platform 42 is provided between the rotating shafts 41.

[0027] The self-tilting assembly 4 also includes a second rotating shaft 43 and an electro-hydraulic actuator 44. The second rotating shaft 43 is longitudinally and symmetrically connected to the right side of the tilting platform 42 and the right end of the base 1 via a second bearing. An electro-hydraulic actuator 44 is provided between each two vertically adjacent second rotating shafts 43. The input end of each electro-hydraulic actuator 44 is electrically connected to the output end of the controller 3. When using the device to perform non-destructive unloading of the same type of heavy ton bag, the worker drives a forklift to place the heavy ton bag vertically from top to bottom into the interior of the tilting platform 42, so that the bottom of the heavy ton bag contacts the bottom wall of the tilting platform 42, with the opening of the heavy ton bag facing upward. Then, the controller 3 activates the electro-hydraulic actuator 44, causing its extension end to drive the second rotating shaft 43 to extend a distance of three (distance three is the distance from the initial position of the tilting platform 42 to the point where it rotates 150 degrees to the right around the axis of the first rotating shaft 41, after which the electro-hydraulic actuator 44 extends further). During the adjustment of the extension distance of the telescopic end of the electro-hydraulic actuator 44, the controller 3 adopts a master-slave mode, with the extension trajectory of the front electro-hydraulic actuator 44 as the master and the extension trajectory of the rear electro-hydraulic actuator 44 as the slave. The current position of the master actuator is fed back in real time by the distance feedback sensor, and this position value is used as the real-time target position of the slave actuator. The controller 3 adjusts the opening of the proportional valve and corrects the extension speed by using a PID algorithm based on the difference between the current position of the slave actuator and the real-time position of the master actuator, so that the slave actuator moves synchronously with the position of the master actuator, thereby realizing the synchronous extension and retraction operation of the extension ends of the two electro-hydraulic actuators 44. The longitudinally adjacent shafts 43 in the device have their longitudinal axes coincident, and the shafts between shafts 41 have their longitudinal axes coincident. Figure 4As shown, the tilting platform 42 automatically tilts 150 degrees to the right around the axis of the rotating shaft 41. The material inside the heavy ton bag slides down the side wall of the tilting platform 42 under the action of gravity from the bag opening. The material inside the heavy ton bag is automatically dumped without damaging the bag body. During this process, the telescopic end and the fixed end of the electro-hydraulic actuator 44 adaptively rotate around the axis of the corresponding rotating shaft 41. The device automatically tilts and guides the material inside the ton bag to unload through the tilting element. The operation is convenient and safe, and it will not damage the structure of the ton bag, so that the ton bag can be reused.

[0028] Platform self-clamping component 5: It is located at the left end of the tilting platform 42. The platform self-clamping component 5 includes a rotating shaft 3 51, clamping claws 52 and a linkage shaft 53. The rotating shaft 3 51 is vertically equidistantly rotatably connected to the front and rear ends of the left side of the tilting platform 42 through bearing 3. The outer arc surface of the rotating shaft 3 51 is provided with clamping claws 52. Vertically adjacent clamping claws 52 are rotatably connected to a linkage shaft 53 through bearing 4.

[0029] The platform self-clamping component 5 also includes a fixed seat 54, a rotating shaft 55, and an electro-hydraulic actuator 56. The fixed seats 54 are respectively located on the left side of the front and rear sides of the tilting platform 42. The rotating shaft 55 is rotatably connected to the fixed seat 54 through a bearing 5. An electro-hydraulic actuator 56 is provided between the rotating shaft 55 and the horizontally adjacent linkage shaft 53. The input end of the electro-hydraulic actuator 56 is electrically connected to the output end of the controller 3.

[0030] The device was initially set as Figure 3As shown in the diagram, both front and rear clamping claws 52 are in the open state. The operator activates the electro-hydraulic actuator 2 56 via controller 3, extending its telescopic end (the telescopic ends of electro-hydraulic actuator 2 56 are fixedly connected to the outer arc surface of the laterally adjacent linkage shaft 53, and the fixed ends of electro-hydraulic actuator 2 56 are fixedly connected to the outer arc surface of the laterally adjacent rotating shaft 4 55). The extension of the telescopic end of electro-hydraulic actuator 2 56 drives the corresponding linkage shaft 53 to move synchronously a distance of one (this distance one is the extension distance of the telescopic end of electro-hydraulic actuator 2 56 from the open state to the 120-degree flipped clamping state; an additional device can be installed on electro-hydraulic actuator 2 56). A magnetostrictive displacement sensor, which can be an existing ES-type plug-in magnetostrictive displacement sensor, is bidirectionally electrically connected to the controller 3. The sensor waveguide of the magnetostrictive displacement sensor is built into the telescopic end of the electro-hydraulic actuator 56. Initially, the controller 3 activates the magnetostrictive displacement sensor. The permanent magnetic ring of the magnetostrictive displacement sensor moves with the telescopic end of the electro-hydraulic actuator 56. The electron head emits a current pulse to generate a magnetic field, which interacts with the magnetic field of the magnetic ring to generate a torsional wave. By calculating the time difference, the absolute position is obtained, and thus the extension of the electro-hydraulic actuator 56 is measured. The telescopic distance of the telescopic end is measured and the measurement result is fed back to the controller 3 as an electrical signal. When the controller 3 receives the result and the distance is reached, it automatically shuts off the electro-hydraulic actuator 2 56. The electro-hydraulic actuator 2 56, through its own oil circuit integrated block, has a bidirectional hydraulic lock and pressure holding mechanism, which allows its telescopic end to be locked in any position and maintain constant output force when the power is off or its own drive unit stops. The electro-hydraulic actuator 1 44 is equipped with a magnetostrictive displacement sensor in the same manner as the electro-hydraulic actuator 2 56, so as to provide feedback on the telescopic distance of the telescopic end of the electro-hydraulic actuator 1 44. Through the same principle, the controller 3 controls the telescopic distance of the electro-hydraulic actuator 3 8. (The stroke is controlled by commands). The linkage shaft 53 drives its fixed clamping claw 52 to rotate 120 degrees around the corresponding rotating shaft three 51 towards the left longitudinal center of the flipping platform 42 (the vertical axes of the vertically adjacent rotating shaft three 51 on the left side of the flipping platform 42 coincide, so that when a single linkage shaft 53 drives its fixed clamping claw 52 to rotate around the corresponding rotating shaft three 51, there will be no jamming during the flipping). During this process, the telescopic end of the electro-hydraulic actuator two 56 adaptively rotates around the corresponding linkage shaft 53, and the fixed end of the electro-hydraulic actuator two 56 adaptively rotates around the corresponding rotating shaft four 55. Figure 1As shown, the clamping claws 52 at both ends rotate axially around the corresponding rotating shaft 51 and radially clamp and fix the heavy ton bag inside the tilting platform 42. During the extension and retraction of the telescopic end of the electro-hydraulic actuator 56, both ends of the electro-hydraulic actuator 56 are rotatably connected to the corresponding shaft, forming a double hinge connection. The axis of the telescopic end of the electro-hydraulic actuator 56 always dynamically coincides with the line connecting the two hinge points. The telescopic end of the electro-hydraulic actuator 56 only transmits pushing and pulling forces along its own axial direction, and hardly generates any additional radial off-center load, thus avoiding damage to the telescopic end of the electro-hydraulic actuator 56 due to radial pressure. The problem is that both ends of the electro-hydraulic actuator 44, like the electro-hydraulic actuator 56, are rotated, which avoids damage to the telescopic end due to radial pressure through the same principle. The bearings in the device are all double-row tapered roller bearings, which can withstand radial and bidirectional axial loads at the same time. They have high rigidity, high load-bearing capacity and excellent running stability, which improves the bearing's load-bearing and limiting capacity for the corresponding shaft components. When the device unloads the material in the ton bag, the device uses the clamping element to radially clamp and limit the tipping of the ton bag, thereby improving its tipping and tipping stability.

[0031] The clamping claws 52 at the front left side and the clamping claws 52 at the rear left side of the flipping platform 42 are vertically staggered. The clamping claws 52 on the front and rear sides increase the clamping surface through the vertical staggered distribution, thereby improving the overall clamping effect of the clamping claws on the left side of the heavy ton bag.

[0032] The outer arc surface of the clamping claw 52 is provided with uniformly distributed reinforcing ribs 6. The reinforcing ribs 6 increase the moment of inertia of the section of the clamping claw 52, ​​thereby improving the strength and rigidity of the clamping claw 52 without significantly increasing the wall thickness of the clamping claw 52, ​​and reducing the probability of deformation during operation.

[0033] Two vertically distributed connecting seats 7 are provided on the upper right wall of the flipping platform 42. An electro-hydraulic actuator 3 8 is located between the connecting seats 7. The input end of the electro-hydraulic actuator 3 8 is electrically connected to the output end of the controller 3. The telescopic end of the electro-hydraulic actuator 3 8 is equipped with a push rod 9. The controller 3 then activates the electro-hydraulic actuator 3 8, causing its telescopic end to move the push rod 9 vertically downward a distance of two (the electro-hydraulic actuator 3 8, like the electro-hydraulic actuator 2 5 6, is equipped with a magnetostrictive displacement sensor, thus providing feedback on the telescopic distance of the electro-hydraulic actuator 3 8. Through the same principle, the controller 3 commands and controls the stroke of the telescopic end of the electro-hydraulic actuator 3 8. Distance two is the vertical downward movement distance of the bottom end of the push rod 9 from its initial state to when it comes into contact with the bottom wall of the heavy tonne bag. This distance can be measured from the connecting seat 7 on the lower side. A circular groove is opened in the middle, and the diameter of the groove is the same as the diameter of the telescopic end of the electro-hydraulic actuator 3 8. When the telescopic end of the electro-hydraulic actuator 3 8 extends or retracts, it slides vertically along the circular groove. Through the sliding connection between the two, the telescopic part of the electro-hydraulic actuator 3 8 is radially protected. This allows the bottom of the top rod 9 to make vertical compression contact with the bottom wall of the heavy ton bag in the tilting platform 42, so as to avoid the heavy ton bag body from being misaligned and separated from the tilting platform 42 during subsequent tilting. After the material in the heavy ton bag is tilted, the controller 3 controls the electrical components in the device to return to the initial state through the same principle, in preparation for the next material tilting of the heavy ton bag. The device automatically limits the vertical movement of the ton bag in the device through electric components to prevent the ton bag from separating and falling off from the device during subsequent tilting and unloading.

[0034] The bottom of the base 1 has evenly distributed mounting holes 10, which make it easy to fix the bottom of the device to the side of the company's small silo or the side of the high-frequency eddy current feeding belt by using anchor bolts through the mounting holes 10.

[0035] The working principle of the non-destructive unloading mechanism for ton bags provided by this invention is as follows: The bottom of the device is fixed to the side of the company's small silo or the side of the high-frequency eddy current feeding belt using anchor bolts through the mounting holes 10. When using the device to non-destructively unload the same type of heavy ton bags, a worker drives a forklift to vertically place the heavy ton bag from top to bottom into the interior of the tilting platform 42, so that the bottom of the heavy ton bag contacts the bottom wall of the tilting platform 42, with the opening of the heavy ton bag facing upwards. Initially, the device is... Figure 3 As shown, both front and rear clamping claws 52 are in the open state. The operator activates the electro-hydraulic actuator 2 56 via controller 3, extending its telescopic end. The extended end of the electro-hydraulic actuator 2 56 drives the corresponding linkage shaft 53 to move synchronously a distance of one. The linkage shaft 53 drives its fixed clamping claw 52 to rotate 120 degrees around the corresponding rotating shaft 3 51 towards the left longitudinal center of the tilting platform 42. During this process, the telescopic end of the electro-hydraulic actuator 2 56 adaptively rotates around the corresponding linkage shaft 53, and the fixed end of the electro-hydraulic actuator 2 56 adaptively rotates around the corresponding rotating shaft 4 55. Figure 1As shown, the clamping claws 52 at both ends rotate axially around the corresponding rotating shaft 3 51 and radially clamp and fix the heavy ton bag inside the tilting platform 42. The clamping claws 52 on both sides are vertically staggered to improve the clamping effect on the left side of the heavy ton bag. The cross-sectional moment of inertia of the clamping claws 52 is increased by the reinforcing ribs 6, which improves the strength and rigidity of the clamping claws 52 without significantly increasing the wall thickness of the clamping claws 52, and reduces the probability of deformation during operation. Then, the controller 3 activates the electro-hydraulic push rod 3 8, which causes its telescopic end to drive the top rod 9 to move vertically downward by a distance of two, so that the bottom of the top rod 9 makes vertical compression contact with the bottom wall of the heavy ton bag inside the tilting platform 42, so as to avoid the heavy ton bag body from being misaligned and separated from the tilting platform 42 during subsequent tilting. Then, the controller 3 activates the electro-hydraulic push rod 1 44, which causes its telescopic end to drive the rotating shaft 2 43 to extend by a distance of three, as shown. Figure 4 As shown, the tilting platform 42 automatically tilts 150 degrees to the right around the axis 41. The material inside the heavy ton bag slides down the side wall of the tilting platform 42 under gravity, without damaging the bag body, automatically emptying the material. During this process, both the telescopic and fixed ends of the electro-hydraulic actuator 44 adaptively rotate around the corresponding axis 41. After the material in the heavy ton bag is emptyed, the controller 3 uses the same principle to restore the electrical components in the device to their initial state, preparing for the next emptying of the heavy ton bag.

[0036] It is worth noting that the controller 3 disclosed in the above embodiments can be FX3U-30MR, the electro-hydraulic actuator 44 and the electro-hydraulic actuator 8 can be DYTZ-1000, the electro-hydraulic actuator 56 can be DYTZ-450, and the controller 3 controls the operation of the electro-hydraulic actuator 44, the electro-hydraulic actuator 56 and the electro-hydraulic actuator 8 using methods commonly used in the prior art.
