Description

Technical Field

[0001] This invention belongs to the field of material transport equipment technology, and in particular relates to a device for preventing material accumulation during continuous unloading. Background Technology

[0002] In material conveying systems, continuous unloading is usually required. That is, the material conveying equipment continuously transports the material to the unloading area, and then the material is guided by the discharge chute to the parallel storage bins. In order to ensure that the transported material does not accumulate, the discharge chute needs to move continuously between the storage bins so as to smoothly guide the material to each storage bin.

[0003] However, during the movement of the discharge chute, it continuously passes between two adjacent storage silos. These silos are typically separated by support beams or expansion joints, and these structures do not allow for openings. Therefore, during continuous unloading, the discharge chute indiscriminately discharges material each time it passes these locations, causing material to accumulate on the support beams or expansion joints. When the material accumulation reaches a certain height, it obstructs the movement of the discharge chute, increases the operating resistance of the unloading equipment, and consequently affects unloading efficiency. Especially at expansion joints, in addition to material accumulation, there is also the risk of falling objects from above. These accumulated materials require regular manual cleaning, and sometimes machine shutdown for cleaning. Furthermore, manual cleaning generates dust. The work of cleaning accumulated materials increases the labor intensity of operators, affects the company's production process, hinders automated management, and cannot guarantee the effective operation of safe and environmentally friendly production.

[0004] Therefore, there is an urgent need for equipment that can prevent material accumulation or enable automatic periodic cleaning to solve the aforementioned problems caused by material accumulation due to continuous unloading.

[0049] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0050] Please refer to Figures 1 to 8 The contents are shown to better understand the specific structure of the invention. A device for preventing material accumulation during continuous unloading, such as... Figures 1-3 As shown, it includes:

[0051] Several storage bins 1 arranged side by side are configured to store delivered materials;

[0052] The discharge chute 2 is movable along the arrangement direction of the plurality of storage bins 1 and is configured to guide the material into each of the storage bins 1;

[0053] Several dispensing units 3 are all located close to each other at the upper ends of two adjacent storage bins 1 and directly below the moving path of the discharge chute 2, which is configured to prevent material from accumulating between two adjacent storage bins 1.

[0054] And several control units (not shown in the figure), which are electrically connected to each of the packaging units 3, and are configured to control the start, stop and operation of the packaging units 3.

[0055] It should be noted that both the storage bin 1 and the discharge chute 2 adopt common structures in the existing technology and should be able to achieve continuous unloading. There are no restrictions on the structure of the two here.

[0056] In specific implementation, the anti-material accumulation device provided by this invention can effectively prevent materials from accumulating between adjacent storage bins 1 during continuous unloading, thereby solving the problems caused by material accumulation, such as reduced unloading efficiency, easy falling objects from heights, increased labor intensity for workers, impact on production process, and inability to guarantee safe and environmentally friendly production. The device also features several dispensing units 3, which can dispense materials into two adjacent storage bins 1, preventing material accumulation between them and ensuring smooth production. Furthermore, the device includes a control unit, which enables automated control of the dispensing units 3, reducing the burden of manual operation and promoting the automation of enterprise production.

[0057] In the embodiments provided by the present invention, such as Figure 4 As shown, the packaging unit 3 includes:

[0058] The flap 301 is swingably mounted on the upper end of the dispensing unit 3 and aligned with the discharge port 201 of the discharge chute 2. It is configured to dispense the material unloaded from the discharge chute 2 into the two adjacent storage bins 1.

[0059] A flip drive unit 302 is disposed at the lower end of the flip plate 301 and is electrically connected to the control unit;

[0060] The flipping transmission unit 303 is disposed at the lower end of the flip plate 301. Its power input end is connected to the power output end of the flipping drive unit 302, and its power output end is connected to the flip plate 301. It can drive the flip plate 301 to swing to the left and right sides of the storage bins 1.

[0061] Material position sensors (not shown in the figure) are installed in two adjacent storage bins 1 and electrically connected to the control unit. They are configured to collect the position information of the material filling in the storage bins 1 and transmit the material filling position information to the control unit.

[0062] The sliding support 304 is located at the bottom of the dispensing unit 3 and is movably installed at the connection between the upper ends of the two adjacent storage bins 1.

[0063] It should be noted that when the number of storage bins 1 is small, the deformation and installation error between two adjacent storage bins 1 can be ignored. Therefore, the upper ends of the two storage bins 1 can be directly connected by the support beam 101; the sub-packing unit 3 can be fixed on the support beam 101.

[0064] It should be noted that the flap 301 is preferably a flat plate made of metal, but other materials such as PVC can also be used depending on the type of material. The flap 301 should be located on the moving path of the discharge chute 2 and aligned with the discharge port 201 of the discharge chute 2.

[0065] It should be noted that the flip drive unit 302 preferably adopts a stepper motor structure, which can be fixedly installed on the upper surface of the sliding support 304 by means of a fixed bracket and screws; the power output end of the flip drive unit 302 is the output shaft of the stepper motor.

[0066] It should be noted that the flipping transmission unit 303 includes a transmission shaft 3031 and a flipping bracket 3032; one end of the transmission shaft 3031 (the power input end of the flipping transmission unit 303) is connected to the output shaft of the flipping drive unit 302, which can be connected to the output shaft of the flipping drive unit 302 by means of a coupling 305, the middle part is welded or screwed to the flipping bracket 3032, and both ends are supported on the upper end face of the sliding support 304 by bearings 306; the upper part of the flipping bracket 3032 (the power output end of the flipping transmission unit 303) is preferably welded or screwed to the lower end face of the flip plate 301.

[0067] It should be noted that the material position sensor preferably adopts an infrared detector from the existing technology, which can detect the filling position of the material in the storage bin 1 by emitting and receiving infrared rays, and transmit the position information to the control unit.

[0068] It should be noted that the control unit is preferably a PLC (PLC is the abbreviation for Programmable Logic Controller), but it can also be a circuit including at least one processor, a circuit including at least one microcontroller, or a combination of multiple circuits or chips, as long as it can achieve the corresponding function. It is understood that for those skilled in the art, the control circuit can also be a common circuit composed of amplifiers, comparators, transistors, MOSFETs, etc., to achieve the corresponding function in a purely hardware manner.

[0069] It should be noted that the working principle of the dispensing unit 3 is as follows: Under normal circumstances, the material chute 2 moves along the unloading path, unloading the material transported by the material conveyor 4 through the discharge port 201 into each storage bin 1. This unloading process is continuous. When a storage bin 1 is full, the material chute 2 will move to the next adjacent storage bin 1, or the material chute 2 will circulate between each storage bin 1 until all storage bins 1 are full. Regardless of the unloading method used, the material chute 2 is always unloading continuously during its movement. When the material chute 2 passes between two adjacent storage bins 1, it will unload the material indiscriminately between the two storage bins 1, causing material accumulation. After using the dispensing unit 3, the tilting drive unit... Under the control of the control unit, the flipping transmission unit 303 drives the flap 301 to swing left and right, which can pour the material unloaded between the two storage bins 1 by the discharge chute 2 into the two storage bins 1, thereby avoiding the accumulation of material. In addition, after adopting the dispensing unit 3, the discharge chute 2 can stop above the dispensing unit 3 for unloading. At this time, the flap 301 swings to one side of the storage bin 1. When the material is filled to a certain extent, the material position sensor will monitor the filling position of the material and send the position information to the control unit. The control unit controls the flipping drive unit 302 to drive the flipping transmission unit 303 and the flap 301 to swing to the other side of the storage bin 1, and continue to unload to the other side of the storage bin 1.

[0070] It should be noted that, as Figure 5 As shown, the sliding support 304 adopts a plate-like structure with an elongated hole 3041, and is fixed to the support beam 101 between two adjacent storage bins 1. Preferably, it is fixed to the support beam 101 by screws at the position of the elongated hole 3041 (the width of the elongated hole 3041 can be slightly larger than the diameter of the screw thread). Since there is a certain error in the position between each pair of storage bins 1, the discharge port 201 of the discharge chute 2 may not be aligned with each sub-packaging unit 3. Therefore, during installation, the front and rear installation positions of the sub-packaging units 3 can be appropriately adjusted through the elongated hole 3041 so that each sub-packaging unit 3 is aligned with the discharge port 201. In addition, if there is a slight misalignment between the two storage bins 1 (in the case of a deformation joint 102 structure), the misalignment can also be offset by the elongated hole 3041 of the sliding support 304.

[0071] In specific implementation, a flipping drive unit 302, a flipping transmission unit 303, and a material position sensor are set up. Under the control of the control unit, the flip plate 301 can be automatically flipped according to the material filling status to distribute the material to the storage bin 1 on the other side, which improves the degree of automation control and reduces the manual burden. A sliding support 304 is set up so that the installation position of each dispensing unit 3 can be adjusted back and forth to ensure alignment with the discharge port 201, which improves the accuracy of unloading.

[0072] In one implementation, such as Figures 6-8As shown, the anti-material accumulation device also includes a servo support unit 5; the servo support unit 5 is located at the lower end of the dispensing unit 3 and is installed at a position close to each other on the upper ends of two adjacent storage bins 1. It is configured to avoid motion interference between the two adjacent storage bins 1 and the dispensing unit 3 and to adjust the horizontal deflection angle of the dispensing unit 3.

[0073] The servo support unit 5 includes:

[0074] Support base 501, the upper end of which is connected to the lower end of the dispensing unit 3;

[0075] The rotating part 502 is installed on the lower end face of the support base 501 and includes an upper rotating part 5021 and a lower rotating part 5022 that are capable of rotating independently of each other and are coaxially arranged.

[0076] The first support rod 503 is connected to the upper rotating part 5021 in the middle, and its two ends are respectively hinged to the upper ends of the two adjacent storage bins 1.

[0077] The second support rod 504 is connected to the lower rotating part 5022 in the middle, and its two ends are respectively hinged to the upper ends of the two adjacent storage bins 1.

[0078] Both the first support rod 503 and the second support rod 504 are telescopic structures, and there is an included angle between the two axes;

[0079] The servo drive unit 505 is mounted on the lower end face of the support base 501 and is electrically connected to the control unit;

[0080] The servo transmission unit 506 has its power input end connected to the power output end of the servo drive unit 505, and its power output end connected to the lower rotating part 5022, which can drive the support base 501 to rotate clockwise or counterclockwise in the horizontal direction.

[0081] An angle sensor 507 is disposed on the support base 501 and electrically connected to the control unit. It is configured to collect the horizontal deflection angle information of the support base 501 and transmit the horizontal deflection angle information to the control unit.

[0082] It should be noted that when there are many storage bins 1, there will be a certain amount of deformation and installation error between two adjacent storage bins 1. Therefore, an expansion joint 102 needs to be set at the upper end between two storage bins 1 to offset the above-mentioned deformation and error. In particular, the slight forward and backward movement of a single storage bin 1 due to changes in the installation terrain, or the slight left and right movement of a storage bin 1 due to the increase in weight after material filling, will cause changes in the position between two adjacent storage bins 1. If the dispensing unit 3 is fixed and straddled between two storage bins 1 in the above manner, there will be movement interference between the dispensing unit 3 and the two storage bins 1, which will cause damage to the components. Therefore, a servo support unit 5 needs to be added to the anti-material accumulation device.

[0083] It should be noted that the support base 501 is preferably a metal plate structure component, and preferably uses a structure such as a fixed bracket and screws to fix the flip drive unit 302 on the upper end surface. Preferably, the two ends of the transmission shaft 3031 are supported on the upper end surface of the support base 501 by the bearing 306.

[0084] It should be noted that the connecting shaft 508 is preferably fixed to the lower end face of the support 501 by welding.

[0085] It should be noted that the rotating part 502 is preferably a double-row radial roller bearing; the bearing structure is that the inner ring is fitted onto the connecting shaft 508 by interference fit or key connection, and the outer part consists of two parallel outer rings that can rotate independently of each other (i.e., the upper rotating part 5021 and the lower rotating part 5022). Circumferentially distributed rollers are made between the inner ring and the two outer rings.

[0086] It should be noted that the first support rod 503 and the second support rod 504 both adopt a metal rod structure, and the middle part is preferably welded to the two sides of the upper rotating part 5021 and the lower rotating part 5022 respectively. The included angle value can be determined according to the width of the expansion joint 102.

[0087] It should be noted that both ends of the first support rod 503 and the second support rod 504 are telescopic structures, preferably using a telescopic axial tubular component fitted at both ends of the rod.

[0088] It should be noted that the two ends of the first support rod 503 and the second support rod 504 are preferably connected to the storage bins 1 on both sides through hinges such as bearing structures.

[0089] It should be noted that the servo drive unit 505 is preferably in the form of a stepper motor, and can be fixed to the lower end face of the support base 501 via a connecting bracket. The output shaft of the stepper motor is the power output end of the servo drive unit 505.

[0090] It should be noted that the servo transmission unit 506 preferably has a pair of meshing bevel gears, including a driving bevel gear 5061 (the power input end of the servo transmission unit 506) and a driven bevel gear 5062 (the power output end of the servo transmission unit 506); the driving bevel gear 5061 is connected to the power output end of the servo drive unit 505; the driven bevel gear 5062 is connected to the lower rotating part 5022 by welding or screws.

[0091] It should be noted that the angle sensor 507 is preferably an inductive angle sensor 507, which can obtain the deflection angle of the support 501 by utilizing the change of coil inductance with the position of the magnetic material.

[0092] It should be noted that the working principle of the servo support unit 5 is as follows: when the dispensing unit 3 is installed between the two storage bins 1 with the expansion joint 102, it is easy to cause motion interference with the storage bins 1. Therefore, the servo support unit 5 is set up. Taking the case where the two storage bins 1 move away from each other as an example (the working process is basically the same when the two storage bins 1 move away from each other, move closer to each other, or have other offsets, so it will not be described again), at this time, both the first support rod 503 and the second support rod 504 extend and rotate around their respective middle parts, the included angle between them decreases, and the upper rotating part 50 21 rotates with the first support rod 503 and the second support rod 504, corresponding to the lower rotating part 5022. Since the driven bevel gear 5062 is fixedly connected to the lower rotating part 5022 and connected to the support base 501 through the driving bevel gear 5061 and the servo drive unit 505, the support base 501 and the dispensing unit 3 will rotate together with the lower rotating part 5022 at a certain angle. This angle causes the flap 301 and the discharge port 201 to not be aligned, resulting in material leakage during unloading. The angle sensor 507 can collect the deflection angle and deflection direction of the support base 501. The data is transmitted to the control unit; the control unit sends a start command to the servo drive unit 505, which drives the lower rotating part 5022 to rotate via the driving bevel gear 5061 and the driven bevel gear 5062. However, due to the large resistance of the lower rotating part 5022 and the second support rod 504 from the two storage bins 1, they do not rotate. Therefore, the driven bevel gear 5062 and the driving bevel gear 5061 react to the servo drive unit 505 and the support base 501, causing the support base 501 to rotate in the opposite direction, thereby restoring the support base 501 and the dispensing unit 3 to their initial positions; when the two storage bins 1... When there is a misalignment in other directions, the changes in the first support rod 503 and the second support rod 504 and the adjustment method of the control unit are the same as the above principle. In short, no matter what kind of deflection occurs in the support seat 501, it can be adjusted to the initial position by the angle sensor 507 and the control unit (although the sliding support 304 can avoid motion interference to a certain extent when the offset of the two storage bins 1 is very small, it cannot automatically adjust the dispensing unit 3 to the initial position), thus avoiding the problem of material leakage caused by the misalignment of the flip plate 301 and the discharge port 201.

[0093] In specific implementation, a servo support unit 5 is set up. By using the servo adjustment method, the angle of the dispensing unit 3 can be adjusted in real time when the flip plate 301 deflects, so as to prevent the material leakage caused by the deviation between the flip plate 301 and the discharge port 201. This realizes the automation control of production and improves production efficiency.
