Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings in conjunction with specific examples. It should be noted that directional terms such as "upper", "lower", "middle", "left", "right", "front", "rear", and the like, referred to in the examples, refer only to the direction of the drawings. Accordingly, the directions used are for illustration only and are not intended to limit the scope of the present invention.
A semi-automatic single granule racking machine is mainly composed of a base 5, a feeding mechanism, an asymmetric oscillating mechanism, a conveying mechanism, a collecting mechanism and a control circuit, as shown in figure 1.
The feeding mechanism is positioned right above the left side of the base 5. The feeding mechanism comprises a hopper 3, a hopper bracket 1, a hopper 2, 2 hopper brackets 4 and 2 rollers 7. The hopper 3 is horizontally arranged right above the left side of the base 5, extends along the left-right direction and has a U-shaped cross section. The conveying hopper of the granules adopts a U-shaped design, and the granules can be distributed in a single row by matching with an oscillating mechanism under the action of the gravity of the granules. The hopper bracket 1 is vertically arranged above the left side of the feeding hopper 3, and the hopper 2 is arranged on the hopper bracket 1. The bottom of the hopper 2 is designed by an oblique plane, the connecting part of the hopper bracket 1 and the feeding hopper 3 is designed by an oblique plane, and the angle of the oblique plane is the same as the cutting angle of the bottom of the hopper 2. Through adjusting the inclined plane angle of 2 bottom bevels of hopper and the department that connects hopper support 1 and hopper 3, come to control the unloading speed of aggregate to can realize 2 dead weight control feeds of hopper. When the inclined plane at the bottom end of the hopper 2 is opposite to the inclined plane at the joint of the hopper bracket 1 and the feeding hopper 3 in the inclined direction, the blanking speed is fastest; the blanking speed gradually becomes slower along with the rotation of the hopper 2 on the hopper bracket 1; when the inclined plane at the bottom end of the hopper 2 is the same as the inclined plane at the joint of the hopper bracket 1 and the feeding hopper 3, the discharging opening is sealed, and discharging is stopped. The upper ends of the 2 hopper supports 4 are respectively fixed below the left side and the right side of the hopper 3, the lower end of each hopper support 1 is provided with 1 roller 7, and the roller 7 is in contact with a roller guide rail 6 arranged on the base 5. The rollers 7 are designed in a concave shape and are matched with the convex shape of the roller guide rails 6 on the base 5, so that the moving direction and the moving stability of the hopper 3 are ensured, as shown in fig. 2.
The asymmetric oscillating mechanism is positioned below the middle part of the hopper 3. The asymmetric oscillation mechanism comprises a movable support plate 11, an oscillation adsorption iron sheet 12, a strong magnetic fixing support plate 8, a strong magnetic electromagnet 9, a weak magnetic electromagnet 13, a weak magnetic fixing support plate 14 and a spring 10. The upper end of the movable support plate 11 is fixed in the middle of the lower part of the feeding hopper 3, and the line segment of the movable support plate 11 is suspended. The lower ends of the strong magnetic fixing support plate 8 and the weak magnetic fixing support plate 14 are fixed on the base 5, and the upper ends of the strong magnetic fixing support plate 8 and the weak magnetic fixing support plate 14 are suspended. The strong magnetic fixed support plate 8 is positioned on the left side of the movable support plate 11, the weak magnetic fixed support plate 14 is positioned on the right side of the movable support plate 11, and the strong magnetic fixed support plate 8 and the movable support plate 11 and the weak magnetic fixed support plate 14 and the movable support plate 11 are connected through the springs 10. The left and right side surfaces of the lower part of the movable support plate 11 are respectively fixed with an oscillating adsorption iron sheet 12. The upper part of the strong magnetic fixed support plate 8 is provided with a strong magnetic electromagnet 9 facing to one side of the movable support plate 11, namely the right side, and the position of the strong magnetic electromagnet 9 is opposite to the position of the oscillating adsorption iron sheet 12 on the right side. The weak magnetic electromagnet 13 is provided on the upper portion of the weak magnetic fixed stay 14 toward the left side, which is the side of the movable stay 11, and the position of the weak magnetic electromagnet 13 is opposite to the position of the oscillating attracting iron piece 12 on the left side. Under the control of the control circuit, after the bilateral asymmetric oscillation mechanism is electrified, the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 are alternately electrified, and different attractive forces are generated to the oscillation adsorption iron sheet 12 due to different magnetism. Under the action of attraction force, the hopper 3 is supported by the roller 7 and the roller 7 bracket to do oscillating motion with different acceleration along the roller guide rail 6. The pellets move in an oscillation towards the conveyor belt 17 under the influence of inertia. Due to the structural design of the spring 10, the movable support plate 11 and the fixed support are prevented from colliding in the moving process of the hopper 3, and the iron sheet collides with the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13, so that the oscillation process is smoothly carried out. The asymmetric oscillation mechanism utilizes a bilateral asymmetric electromagnetic oscillation principle to enable the hopper 3 to generate different front and back accelerations under the action of asymmetric electromagnetic force, the front acceleration is greater than the back acceleration, the granules move back under the action of inertia, and then the granules are distributed in a single row under the action of self weight and oscillation of the hopper 3.
The conveying mechanism is positioned right above the middle part of the base 5. The transmission mechanism comprises a transmission belt 17, 2 transmission rotating wheels 15, 2 transmission brackets 18 and a transmission motor 16. The conveyor 17 is horizontally disposed right above the right side of the base 5 and extends in the left-right direction. The level of the conveyor belt 17 is lower than the level of the hopper 3 and the left end of the conveyor belt 17 is located directly below the right end of the hopper 3 and allows the granules from the hopper 3 to fall onto the conveyor belt 17. The lower end of 2 transmission supports 18 is fixed on the base 5, 1 transmission rotating wheel 15 is arranged above each transmission support 18, and the conveyor belt 17 is nested on the 2 transmission rotating wheels 15. The output end of the transmission motor 16 is connected with the transmission rotating wheel 15, and controls the transmission rotating wheel 15 to rotate clockwise so as to drive the upper surface of the conveyor belt 17 to move from left to right, and the aggregate sent out by the feeding mechanism is sent to the aggregate mechanism.
The material collecting mechanism is positioned right above the right side of the base 5. The material collecting mechanism is shown in fig. 3 and comprises a material collecting bin 27, an infrared transmitting tube 19, an infrared receiving tube 20, a partition plate 23, an upper bin opening electromagnet 24, a partition plate adsorption iron sheet 25, a lower bin opening electromagnet 26, a display screen 21 and a keyboard 22. The aggregate bin 27 is fixed on the right side of the base 5 and is a hollow cuboid as a whole. The pan feeding mouth of arc fretwork design has been seted up on the upper portion of collection feed bin 27 left side wall, and the discharge gate has been seted up to the lower part of collection feed bin 27 right side wall. An upper bin opening electromagnet 24 is arranged at the upper side of a discharge opening of the collecting bin 27, and a lower bin opening electromagnet 26 is arranged at the lower side of the collecting bin 27. The discharge port of the aggregate bin 27 is opposite to the right end of the conveyor belt 17.
The infrared emission tube 19 and the infrared receiving tube 20 are disposed in the inner cavity of the aggregate bin 27 and fixed relatively in the middle of the front and rear side walls of the aggregate bin 27. The display screen 21 and the keyboard 22 are provided on the outer side wall of the bin 27. The infrared transmitting tube 19 and the infrared receiving tube 20 form an infrared counter, which is installed at a position forming an included angle of 45 degrees with the conveyor belt 17, wherein the infrared transmitting tube and the infrared receiving tube are respectively installed at two sides of the collecting bin 27 adjacent to the conveyor belt 17, and the positions are opposite. The granular material is driven by the conveyor belt 17 to move to the right end of the conveyor belt 17, and when the granular material reaches a position forming an angle of 45 degrees with the plane of the conveyor belt 17, the granular material falls into the aggregate bin 27 under the action of the dead weight. At this time, the signal from the infrared transmitting tube 19 is blocked by the granular material, the signal received by the infrared receiving tube is blocked, and the counter counts the falling granular material. And the control circuit is used for processing the data and controlling the states of the bilateral asymmetric oscillation mechanism, the transmission motor 16 in the conveyor belt 17 and the port of the collecting bin 27 according to the data, thereby achieving the accurate and quick control effect.
One end of the clapboard 23 is hinged at the lower part of the left side wall of the aggregate bin 27, and the other end of the clapboard 23 is provided with a clapboard adsorption iron sheet 25. When the control circuit controls the electrification of the electromagnet 24 on the bin opening, the partition board adsorption iron sheet 25 is attached to the electromagnet 24 on the bin opening, and the discharge hole of the material collecting bin 27 is closed; when the control circuit controls the lower bin opening electromagnet 26 to be electrified, the partition plate adsorption iron sheet 25 is attached to the lower bin opening electromagnet 26, and the discharge hole of the aggregate bin 27 is opened, so that the aggregate can be automatically discharged after reaching the specified quantity.
The control circuit is connected with the strong magnetic electromagnet 9, the weak magnetic electromagnet 13, the transmission motor 16, the infrared transmitting tube 19, the infrared receiving tube 20, the upper hatch electromagnet 24, the lower hatch electromagnet 26, the display screen 21 and the keyboard 22. The strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 are used for controlling the movement of the asymmetric oscillation mechanism, so that the hopper 3 generates different acceleration in the front and back directions under the action of asymmetric electromagnetic force, and further, the granules are distributed in a single row under the action of self weight and the oscillation of the hopper 3. The transmission motor 16 controls the movement of the conveying mechanism, so that the granular materials falling into the feeding mechanism enter the material collecting mechanism. The infrared emission tube 19 and the infrared receiving tube 20 are used for counting the granules. The upper bin opening electromagnet 24 and the lower bin opening electromagnet 26 are used for controlling the partition plate 23 to move, so that the opening and closing of the discharge opening of the material collecting bin 27 are realized. The display screen 21 is used for displaying the total number of the particle counts, the particle subpackaging times and the current count of the subpackaging. The button is used for setting up single partial shipment quantity, and asymmetric oscillation mechanism controls the motion state of hopper 3 through switching on or off.
The minimum control system module of the control circuit takes AT89S52 as a main control chip and adopts an 11.0592MHZ crystal oscillator to construct a minimum control system. The transmission motor 16 module of the conveyor belt 17 takes a four-phase five-wire transmission motor 1628BYJ48 as a power source of the system, and is matched with a driving circuit taking L298N as a core to realize power transmission under the time sequence control of AT89S 52.
JLX12864G-086 is selected as a display interface of the system for the display screen 21, and data information such as setting parameters and counting data is mainly displayed. The keyboard 22 adopts a 4*4 matrix keyboard 22, is connected with a P0 port of the AT89S52 and is externally connected with a pull-up resistor. The control keyboard 22 is mainly used for data setting and related control operation of the system.
The asymmetric oscillation driving circuit comprises diodes D9-D10, darlington tubes Q1-Q2 and resistors R4-R5; the base electrode of the Darlington tube Q1 is connected with the output end of the controller through a resistor R4, and the base electrode of the Darlington tube Q2 is connected with the output end of the controller through a resistor R5; the drain electrode of the Darlington tube Q1 is divided into 2 paths, one path is connected with a power supply Vcc through a diode D9, and the other end is connected with the power supply Vcc through a strong magnetic electromagnet 9; the drain electrode of the Darlington tube Q2 is divided into 2 paths, one path is connected with a power supply Vcc through a diode D10, and the other end is connected with the power supply Vcc through a weak-magnetism electromagnet 13; the source electrode of the Darlington tube Q1 and the source electrode of the Darlington tube Q2 are simultaneously connected with the ground GND. See fig. 4. The asymmetric oscillation mechanism is composed of 2 electromagnets E1 and E2 which are symmetric, and the magnetism of E1 is stronger than that of E2. E1 and E2 are respectively driven by NPN and PNP Darlington tubes, the base electrodes of the two Darlington tubes are connected in common and are controlled by PWM waves output by a port P3.1 of AT89S 52. The circuit structure ensures that the electromagnets E1 and E2 can only be singly started at the same time, and the electromagnetic oscillation structure can be expressed as the back-and-forth expansion under the control of PWM waves. If the duty ratio alpha of the PWM wave is configured so that the start time of E1 and E2 in one period is different, the electromagnetic oscillation structure can make the speed of the granular material moving toward E1 different. When the alpha =1, the electromagnetic oscillation structure shows balanced vibration, and the granular material moves at a basic speed; when alpha is greater than 1, the electromagnetic oscillation structure shows deviation to E1 vibration, the speed of the hopper 3 moving to E1 is increased, and the speed of the granular materials moving to E2 under the action of inertia is increased; when alpha <1, the electromagnetic oscillation structure shows deflection towards E2 vibration, the speed of the hopper 3 moving towards E1 is reduced, and the speed of the granular material moving towards E2 under the action of inertia is reduced. And the larger | α -1| is, the more conspicuous the deflection vibration of the electromagnetic oscillating structure becomes.
The infrared counter is composed of an infrared transmitting tube and an infrared receiving tube and is arranged at a position where the included angle between the aggregate bin 27 and the plane of the conveyor belt 17 is 45 degrees. When the system operates, the infrared transmitting tube transmits infrared rays, and when no granules slide down the channel, the infrared receiving tube can normally receive the infrared rays and output high level; if the pellets slide down, the infrared ray is blocked, and the infrared ray receiving tube 20 cannot receive the infrared ray, and outputs a low level. Based on the principle, the number of the granular materials can be obtained by counting the output falling edges of the infrared receiving tubes, so that the counting function is realized.
The bin opening driving circuit comprises diodes D11-D12, darlington tubes Q3-Q4 and resistors R7-R8; the base electrode of the Darlington tube Q3 is connected with the output end of the controller through a resistor R7, and the base electrode of the Darlington tube Q4 is connected with the output end of the controller through a resistor R8; the drain electrode of the Darlington tube Q3 is divided into 2 paths, one path is connected with a power supply Vcc through a diode D11, and the other end is connected with the power supply Vcc through the lower cabin opening electromagnet 26; the drain electrode of the Darlington tube Q4 is divided into 2 paths, one path is connected with a power supply Vcc through a diode D12, and the other end is connected with the power supply Vcc through an electromagnet 24 on the bin opening; the source electrode of the Darlington tube Q3 and the source electrode of the Darlington tube Q4 are simultaneously connected with the ground GND. See fig. 5. The discharge port of the collecting bin 27 is controlled by 2 symmetrical electromagnets E3 and E4, which are respectively driven by NPN and PNP Darlington tubes, the base electrodes of the two Darlington tubes are connected in common and controlled by a P1.4 port of AT89S 52. When P1.4 outputs high level, E3 is started, E4 is stopped, the partition plate 23 moves to E3, and the bin opening is opened; when P1.4 outputs a low level, E3 stops, E4 starts, diaphragm 23 moves towards E4, and the hatch closes.
When the racking machine is used, a power switch of the control circuit is turned on, and the racking times and the single racking quantity are set through the keys. The lower oblique plane of the hopper 2 is rotated to the position coinciding with the feeding hopper 3, and then the granular particles to be subpackaged are poured into the hopper 2. The granules fall from hopper 2 into feed hopper 3 where they are initially arranged. Under the action of the asymmetric oscillation mechanism, the granules move towards the direction of the conveyor belt 17 in oscillation by inertia, and when the granules move to the edge of the hopper 3, the granules fall from the hopper 3 onto the conveyor belt 17. The moving conveyor 17 distributes the falling granules at different times to different locations on the conveyor 17, with a certain spacing between adjacent granules. When the granules fall from the tail end, namely the right end, of the conveyor belt 17 to the feeding port of the aggregate bin 27, the falling granules block the infrared receiving tube from receiving infrared rays emitted by the infrared emitting tube, the infrared counter catches granule signals, and the subpackaging count is added and displayed on the display screen 21. When this count value reaches and sets for single partial shipment numerical value, strong magnetism electro-magnet 9 and weak magnetism electro-magnet 13 outage among the asymmetric oscillation mechanism, conveyer belt 17 drive motor 16 outage, 24 outage on the door, 26 circular telegrams of electro-magnet under the door, baffle 23 is under the effect of gravity and electromagnetic attraction, around 23 pivot downstream of baffle, adsorb on electro-magnet 26 under the door, the discharge gate of collection feed bin 27 is opened, the aggregate falls into in the outside container from collection feed bin 27.
