[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0029] This example provides a discharge device, such as... Figure 1 As shown, the discharging device includes a storage unit 1, a discharging assembly 2, and a first driving assembly 3. The storage unit 1 adopts a cylindrical structure, specifically a cylindrical structure. The top of the storage unit 1 has an opening, and material is stored within it. The material is fed in through the opening at the top of the storage unit 1. In this example, the material used is a metal ball bearing. Figure 2 As shown, the bottom of the storage component 1 is provided with a first discharge hole 11. The balls are discharged from the first discharge hole 11. The diameter of the first discharge hole 11 is set to be 5-10% larger than the diameter of the balls. If the diameter of the balls is 10mm, the diameter of the first discharge hole 11 is set in the range of 10.5mm to 11mm. The diameter of the first discharge hole 11 is slightly larger than the diameter of the balls to ensure that the balls pass through smoothly and that the balls pass through one by one in sequence.
[0030] like Figure 3 As shown, the discharge assembly 2 includes a moving part 21 and a fixed part 22, as... Figure 4 As shown, a sandwich 23 is formed inside the fixed part 22, and the movable part 21 is disposed in the sandwich 23 and can move within the sandwich 23. The fixed part 22 is connected to the bottom of the storage component 1. A second discharge hole 211 is formed at one end of the movable part 21. The diameter of the second discharge hole 211 is the same as the diameter of the first discharge hole 11. The movable part 21 can move within a preset range. The starting point of the preset range is defined as the first preset position, and the ending point of the preset range is defined as the second preset position. The movable part 21 transports the material from the first preset position to the second preset position, and then returns from the second preset position to the first preset position to transport the material again, and so on.
[0031] like Figure 5 As shown, the second discharge hole 211 has a chamfer 212 on the side near the storage component 1. The chamfer 212 is set to 45° so that the ball can be guided to slide smoothly into the second discharge hole 211 when it approaches the hole, and prevent the ball from getting stuck at the edge of the hole.
[0032] In one implementation, when the ball falls from the first discharge hole 11 to the second discharge hole 211, the ball first contacts the chamfered area 212 of the hole opening. The 45° chamfer provides an inclined surface for the ball, guiding it toward the center of the second discharge hole 211 and allowing it to fall stably into the second discharge hole 211. At the same time, the chamfered area 212 prevents the ball from directly contacting the sharp edge of the second discharge hole 211, reducing wear caused by collision and preventing the ball from rebounding.
[0033] like Figure 6 As shown, the fixing part 22 has a third discharge hole 225 at one end near the second preset position. When the moving part 21 is in the first preset position, the second discharge hole 211 is connected to the first discharge hole 11, and the material falls from the first discharge hole 11 into the second discharge hole 211. When the moving part 21 is in the second preset position, the second discharge hole 211 is connected to the third discharge hole 225, and the material falls from the second discharge hole 211 into the third discharge hole 225.
[0034] The second discharge hole 211 is located above the fixed part 22. When the moving part 21 is within a preset range other than the third discharge hole 225, the bottom channel 224 of the second discharge hole 211 is blocked by the fixed part 22. At this time, the material is inside the second discharge hole 211. When the moving part 21 moves to the second preset position, the bottom channel 224 of the second discharge hole 211 is connected to the third discharge hole 225, and the material can fall smoothly.
[0035] The storage component 1 overlaps with at least a portion of the fixing part 22. If the fixing part 22 overlaps with the first discharge hole 11, a fourth discharge hole 223 is also provided on the fixing part 22. The fourth discharge hole 223 is connected to the first discharge hole 11. The material in the storage component 1 can continuously pass through the first discharge hole 11 and the fourth discharge hole 223, and then reach the second discharge hole 211 of the moving part 21.
[0036] In one example, such as Figure 7 As shown, the fixing part 22 is composed of two parts spliced together, namely the first part 221 and the second part 222. The first part 221 is connected to the storage component 1. The first part 221 coincides with at least a part of the fixing part 22. If the first part 221 coincides with the first discharge hole 11, then the first part 221 is provided with a fourth discharge hole 223. The fourth discharge hole 223 is connected to the first discharge hole 11. The material in the storage component 1 can continuously pass through the first discharge hole 11 and the fourth discharge hole 223, and then reach the second discharge hole 211 of the moving part 21. The second part 222 is connected to at least a part of the first part. A channel 224 is opened at the bottom of the first part 221. The moving part 21 is disposed in the channel 224 and can move in the channel 224. A third discharge hole 225 is opened on the second part 222. The third discharge hole 225 forms a material dropping channel 224.
[0037] like Figure 8 As shown, the first drive assembly 3 includes a double-acting cylinder 31, a cylinder tail support 32, a cylinder fixing support 33, and a cylinder ejection support 34. The cylinder includes a cylinder body and a piston rod. The cylinder tail support 32 is located at the tail of the cylinder body and is connected to the discharge assembly 2. The cylinder fixing support 33 is located at the head of the cylinder body and is connected to the discharge assembly 2. The cylinder ejection support 34 is located at one end of the piston rod and is connected to the moving part 21. The piston rod drives the cylinder ejection support 34 to move, and the cylinder ejection support 34 then drives the moving part 21 to move.
[0038] In one implementation, the extension and retraction motion of the double-acting cylinder 31 described above drives the moving part 21 to reciprocate, causing the balls to enter the third discharge hole 225 through the second discharge hole 211, completing the discharge action. Specifically, the double-acting cylinder 31 has two independent air inlets, which control the extension and retraction of the cylinder respectively. The cylinder body is fixed, and the piston rod is connected to the moving part 21, driving the moving part 21 to reciprocate. In the initial state, the moving part 21 is located in the first preset position, ready to receive the balls, the cylinder is in the retracted state, the second receiving hole is aligned with the first discharge hole 11, waiting for the balls to enter; when the balls fall into the second discharge hole 211, pressure is applied to one of the air inlets, the piston rod extends, and the moving part 21 moves along the channel 224. After the piston rod extends one unit, the moving part 21 reaches the second preset position, rolls into the third discharge hole 225, the airflow direction is switched, the air inlet exhausts, the other air inlet is pressurized, the piston rod retracts, and the moving part 21 returns to the first preset position, ready to receive the next batch of balls.
[0039] The discharge device also includes a limiting component. It is understood that the moving part 21 is disposed in the interlayer 23 of the fixed part 22. During the movement, at least a part of the moving part 21 remains within the interlayer 23. A channel 224 for the moving part 21 is formed within the interlayer 23. This channel 224 can serve as a guide groove, which corresponds to the guide surface of the moving part 21. The width of the guide groove is slightly larger than the width of the moving part 21, allowing the moving part 21 to move axially while avoiding radial displacement. Specifically, the gap between the guide groove and the moving part 21 is set to 0.1 mm to 0.2 mm to ensure that the moving part 21 does not move significantly in the radial direction. On the other hand, when a part of the moving part 21 moves outside the interlayer 23, the path of the moving part 21 is controlled by the limiting component. The limiting component is a symmetrically arranged rectangular structure located on both sides of the moving part 21 and closely attached to the moving part 21, forming a clamping structure for the moving part 21. The limiting component is fixed on the fixed part 22 and parallel to the path of the moving part 21.
[0040] As shown in the figure, Figure 9 As shown, the discharge device also includes a rotating component 4 and a second drive assembly 5, such as... Figure 10 As shown, the rotating component 4 includes a turntable 41 and a brush 42. The second drive assembly 5 includes a DC geared motor, a motor mounting plate, and a coupling. Specifically, the motor mounting plate is connected to the top of the storage component 1, and a through hole is provided in the center of the plate. The motor is mounted on the motor mounting plate, and the extension shaft of the motor extends from the through hole to the bottom of the storage component 1. The coupling connects the extension shaft and the turntable 41. The brush 42 is inserted into the side of the turntable 41 and is located at the bottom of the storage component 1. The brush bristles are dense and maintain an appropriate distance from the bottom of the storage component 1 to ensure that the brush 42 can effectively contact the ball and sweep it toward the first discharge hole 11 when it rotates.
[0041] In one implementation, the motor provides low-speed, high-torque output, driving the brush 42 to rotate slowly. During the rotation, the brush 42 gradually contacts the balls at the bottom of the storage component 1. The rotation of the brush 42 pushes the balls toward the first discharge hole 11, and the balls are discharged one by one under the action of gravity.
[0042] In one example, such as Figure 10 As shown, the brush 42 has a double-row structure. The upper row of brushes 42 is inserted into the upper part of the turntable 41, and the lower row of brushes 42 is inserted into the lower part of the turntable 41. The upper and lower rows of brushes 42 are arranged in parallel to form a precisely coordinated material discharge area. The upper row of brushes 42 can guide the upper ball downwards and prevent the ball from accumulating in the storage component 1. The lower row of brushes 42 is adjacent to the first discharge hole 11 and is responsible for accurately pushing the ball towards the first discharge hole 11 to ensure that the ball is discharged one by one. The upper and lower rows of brushes 42 are driven to rotate simultaneously through the coupling.
[0043] The discharge device also includes a support and a mounting component. The support has a mounting section, one end of which is located within the mounting section, and the other end is connected to the storage component 1 and / or the discharge assembly 2. Specifically, the mounting section adopts a chute structure, which can be two parallel vertical chutes that run through the upper and lower parts of the support. Through the chute design, the height of the discharge assembly 2 can be freely adjusted within a certain range to adapt to different sizes and types of receiving containers or production conditions. The edges of the chute are reinforced to increase its rigidity and prevent deformation during repeated position adjustments. The discharge assembly 2 and the storage component 1 are mounted on the mounting section via the mounting component. The mounting component can move along the chute direction of the mounting section. The mounting component is equipped with locking bolts, which, when tightened, fix the discharge assembly 2 and the storage component 1 to the target position on the mounting section, ensuring that the discharge assembly 2 operates stably without displacement.
[0044] The bottom of the bracket is equipped with a base for fixing the bracket to the work platform of the production line.
[0045] In one implementation, this device is used in an assembly line and is installed on the work platform of the assembly line. Specifically, the bracket is first fixed to the work platform through the mounting holes on the base, and then the storage component 1 and the discharge component 2 are fixedly connected. The combination of the storage component 1 and the discharge component 2 is inserted into the mounting part of the bracket through the mounting part and adjusted to the target position. It is then fixed by locking bolts. When it is necessary to adjust the height of the discharge component 2 to adapt to different working conditions, the operator loosens the locking bolts on the mounting part and moves the discharge component 2 up or down to reach the required height. During the adjustment process, the structure of the chute provides vertical guidance, so that the discharge component 2 always stays in the center position of the bracket during the sliding process and does not deviate.
[0046] Furthermore, the mounting component includes two mounting plates that are fixedly connected. One mounting plate is fixed to the mounting part, and the other mounting plate is connected to the bottom of the storage component 1, or the other mounting plate is connected to one side of the discharge component 2.
[0047] In one example, a conveyor belt is provided below the discharge component 2. The conveyor belt is located directly below the third discharge hole 225. When the material is pushed out from the discharge component 2, it falls naturally by gravity and falls directly onto the conveyor belt after passing through the third discharge hole 225, or falls into other materials on the conveyor. The conveyor belt transports the material to the designated position.
[0048] Furthermore, the conveyor belt surface employs a cross-grid anti-slip pattern. The grid-like patterns are arranged in a crisscross pattern at preset intervals to form an anti-slip surface, suitable for conveying small materials that are prone to rolling, such as balls and granules. Specifically, the depth of the pattern is set to 0.5mm to 1mm. This depth range provides additional friction for the material without affecting the overall smoothness of the conveyor belt. The width of each pattern is set to 1mm to 2mm, and the grid spacing is set to 5mm to 8mm to achieve a balance between friction and surface smoothness.
[0049] In one example, the conveyor belt surface is coated with a layer of wear-resistant and anti-slip silicone. The anti-slip coating has excellent friction performance and wear resistance, making it suitable for use in continuous operation. The thickness of the anti-slip silicone is set to 0.2mm to 0.5mm to ensure that the coating surface is uniform. When the material falls onto the conveyor belt, it ensures that the material is stably supported as soon as it enters the conveyor belt, avoiding excessive sliding or rolling.
[0050] In one implementation, a speed control valve is used to control the movement speed of the cylinder. The speed control valve can be a solenoid valve, used to adjust the intake or exhaust flow of the cylinder, thereby controlling the piston movement speed of the cylinder. Specifically, the speed control valve is installed on the intake channel 224 of the cylinder. According to the weight of the material and the required discharge speed, the speed control valve adjusts the size of the airflow channel 224 by adjusting the adjusting screw or by electronic control to control the airflow entering the cylinder. When it is necessary to speed up the discharge speed, the speed control valve increases the airflow, and the cylinder piston moves faster; when it is necessary to slow down the discharge speed, the speed control valve decreases the airflow, and the cylinder piston moves slower.
[0051] like Figure 11 As shown, a detection hole 226 is provided on one side of the fixing part 22. The detection hole 226 is connected to the third discharge hole 225, and an inductive sensor 227 is provided inside it. The inductive sensor 227 is used to detect the material passing through the third discharge hole 225.
[0052] In one implementation, an inductive sensor 227 is used to detect material discharge signals. The inductive sensor 227 is installed on the side of the material discharge path, so that its sensing area covers the path through which the material passes. When the material is a steel ball, the inductive sensor 227 works by generating an alternating electromagnetic field. When the steel ball enters the sensing area, eddy currents are generated inside the steel ball. The eddy currents affect the electromagnetic field of the coil of the inductive sensor 227, causing a change in the inductance of the coil. The inductive sensor 227 converts the detected change in inductance into an electrical signal and outputs it. Specifically, when the steel ball passes through the third discharge hole 225, the inductive sensor 227 outputs a material discharge signal; if no material passes through, the inductive sensor 227 maintains a no-material signal and does not output a signal, indicating that the current discharge path is empty.
[0053] Understandably, the quantity of material discharged is counted based on the material discharge signal. Each time the inductive sensor 227 detects a discharge signal, the count is incremented by one, which is convenient for monitoring the production progress. Alternatively, the count can be divided into periodic statistics such as hourly, shift, or daily statistics according to production needs, and the count is reset after each statistical period ends.
[0054] A through-beam sensor is installed inside the storage unit 1, which is used to detect the content of material inside the storage unit 1.
[0055] In one implementation, the through-beam sensor includes a transmitter and a receiver. The material is detected by emitting a light beam from the transmitter and monitoring the light reception at the receiver. Specifically, the transmitter emits a light beam, which can be infrared light or laser light, and the receiver receives the light beam. The transmitter and receiver are positioned at a preset height on the inner wall of the storage unit 1, and the preset height is the same as the height of the light beam.
[0056] When the material in storage unit 1 is higher than the preset height, the material blocks the light beam, and the receiver cannot receive the light signal. At this time, the through-beam sensor will remain in the blocked state, indicating that the material in storage unit 1 is sufficient. When the material in storage unit 1 drops below the preset height, the light beam can be transmitted to the receiver. At this time, the receiver receives the light signal, and the through-beam sensor will generate a material shortage state, indicating that material needs to be replenished.
[0057] With the double-row rotating brush 42 structure adopted in this example, the ball material can be discharged continuously and evenly under the drive of the DC geared motor, effectively avoiding the problem of poor discharge caused by material accumulation or jamming in traditional discharge devices; the modular structure makes it easier to disassemble and replace the various parts of the discharge device; by setting the inductive sensor 227 and the through-beam sensor, the material status and discharge quantity of the storage device 1 can be accurately detected.
[0058] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
