Description

Technical Field

[0001] The present invention relates to the technical field of silos, and more particularly to a storage silo with an automatic feeding function. Background Art

[0002] With the rapid development of industrial automation and intelligent manufacturing, the demand for the high efficiency and flexibility of warehousing and logistics systems has become increasingly prominent. Traditional silos mostly rely on manual or semi-automatic methods for material access and storage, suffering from problems such as low feeding efficiency, frequent manual intervention, easy occurrence of material residue or jamming. Especially in fields such as electronic components and precision machining, where the material specifications are diverse and the turnover frequency is high, the fixed silos in the prior art are difficult to adapt to the dynamic production rhythm and lack the ability of real-time inventory monitoring, which is likely to lead to production interruption or resource waste.

[0003] The existing silos mainly have the following problems: (1) No buffering treatment is carried out on the trays, resulting in poor tray stability; (2) No dust removal treatment is carried out on the trays, and after long-term operation, the operation becomes unsmooth. Summary of the Invention

[0004] The purpose of the present invention is to provide a storage silo with an automatic feeding function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: A storage silo with an automatic feeding function, including a negative pressure system and a control system, including a frame, on which a storage bin is installed. A sleeve is sleeved inside the storage bin. Two sets of sliding plates are slidably installed opposite to each other inside the sleeve. Conveyor belts are installed on both sets of sliding plates. A number of carrier plates are installed on the conveyor belts, and trays are placed on the carrier plates. The negative pressure system is connected to the conveyor belts and the carrier plates. A receiving plate is installed below the sleeve, and two sets of tray seats are installed below the storage bin. A feeding track is installed between the two sets of tray seats.

[0006] Two sets of rollers are in contact with both sides of the conveyor belt. The interiors of the two sets of rollers are of electric roller structure. A coil is installed between the two sets of rollers. The two ends of the coil are electrically connected to the control system. The coil and the two sets of rollers are both installed on the sliding plates. The conveyor belt is hollow inside, and a shielding film is arranged inside the conveyor belt. A magnetorheological fluid is arranged between the conveyor belt and one side of the shielding film. The magnetorheological fluid is within the magnetic field of the coil. A dust removal chamber is formed on the other side of the conveyor belt and the shielding film. The dust removal chamber is located outside the magnetorheological fluid;

[0007] A number of adsorption holes are provided in the conveyor belt between two adjacent load-carrying plates. One-way valves are installed in a number of the adsorption holes. A number of the adsorption holes are all communicated with a dust removal chamber. The dust removal chamber is connected to the inlet of an air slip ring through a pipeline. The outlet of the air slip ring is connected to a negative pressure system through a pipeline. The air slip ring is installed on a sliding plate, and the negative pressure system is installed on a frame.

[0008] The inside of the load-carrying plate is hollow. A number of negative pressure holes are provided in the load-carrying plate. A number of the negative pressure holes are all communicated with the inside of the load-carrying plate. The inside of the load-carrying plate is connected to the inlet of the air slip ring through a pipeline. Electromagnetic valves and flow meters are installed in the pipelines connected to the inlet of the air slip ring. The electromagnetic valves and the flow meters are both electrically connected to a control system.

[0009] Suspension shafts are connected between the four corners of the receiving plate and the storage box. The suspension shafts are of a telescopic structure. Telescopic springs are sleeved on the suspension shafts. The telescopic springs connect the receiving plate and the storage box. The two ends of the telescopic springs are electrically connected to the control system. A rectangular groove is provided in the middle of the receiving plate. The size of the rectangular groove is larger than the size of the tray. A displacement sensor is installed on the receiving plate.

[0010] A number of sliding grooves are provided on the receiving plate outside the rectangular groove. Transverse rods are slidably installed in the sliding grooves. Transverse springs are connected between the transverse rods and the receiving plate. Longitudinal rods are slidably installed on the transverse rods. Suction cups are provided at the upper ends of the longitudinal rods. Longitudinal springs are connected between the suction cups and the transverse rods. The two ends of the transverse springs and the longitudinal springs are both electrically connected to the control system. The suction cups are connected to the negative pressure system through pipelines.

[0011] Two groups of the tray seats are both installed on the frame. A number of positioning cylinders are installed on the tray seats. A number of the positioning cylinders are connected to the negative pressure system. Proximity switches are installed on the tray seats. The proximity switches are electrically connected to the control system.

[0012] The feeding track includes a feeding motor and a feeding guide rail. The feeding guide rail is installed on the frame. Feeding rollers are rotatably installed at both ends of the feeding guide rail. A slider is slidably installed on the feeding guide rail. The output shaft of the feeding motor is connected to one of the feeding rollers. The feeding motor is installed on the feeding guide rail. A transmission belt is sleeved between two groups of the feeding rollers. The slider is connected to the transmission belt. A support plate is installed on the slider.

[0013] A buffer plate is installed above the support plate. A number of guide posts are provided on the buffer plate. A number of the guide posts pass through the support plate. A sliding connection is formed between the guide posts and the support plate.

[0014] An adjustment motor is installed in the middle of the support plate. The output shaft of the adjustment motor passes through the support plate and is connected to a transmission shaft. The outer side of the transmission shaft is splined to an adjustment plate. A shock-absorbing spring is installed on the outer side of the adjustment plate. Two sets of extension plates are arranged on the outer side of the adjustment plate. One set of extension plates is higher than the other set. The two sets of extension plates are respectively inserted between adjacent turns of the shock-absorbing spring. The upper end of the shock-absorbing spring is installed on a buffer plate. Another set of displacement sensors are installed on both sets of extension plates.

[0015] By adjusting the effective number of turns of the shock-absorbing spring, the shock-absorbing ability of the shock-absorbing spring for the material tray can be adjusted to meet different usage scenarios. The effective number of turns refers to the number of turns of the shock-absorbing spring between the buffer plate and the extension plate. The more the effective number of turns of the shock-absorbing spring, the stronger the shock-absorbing ability of the shock-absorbing spring.

[0016] The control system drives the transmission shaft to rotate through the adjustment motor. The transmission shaft drives the adjustment plate to rotate. The adjustment plate drives the two side extension plates to rotate accordingly. Since the two side extension plates are respectively inserted into the shock-absorbing spring between adjacent turns, and the adjustment plate and the transmission shaft are splined, when the extension plate rotates, it moves downward at the same time, making the effective number of turns of the shock-absorbing spring between the buffer plate and the extension plate increase, and the shock-absorbing ability of the shock-absorbing spring becomes stronger. The adjustment plate also drives the buffer shaft to move downward at the same time, and the ratchet teeth on the buffer shaft move downward accordingly.

[0017] When the extension plate moves to the set position, the displacement sensor on the extension plate feeds the displacement data back to the control system. The control system energizes the electromagnet. The electromagnet is a push-pull electromagnet. The telescopic rod is the component that reciprocates on the electromagnet. The telescopic rod on the electromagnet pushes the pawl to engage with the ratchet teeth, making the buffer shaft unable to move downward, and further making the extension plate and the adjustment plate unable to move, realizing the adjustment of the buffer shock-absorbing ability.

[0018] A buffer shaft is arranged on the lower side of the adjustment plate. The buffer shaft passes through the support plate. A number of one-way ratchet teeth are arranged on the buffer shaft. An electromagnet is installed on the support plate on one side of the buffer shaft. A pawl is installed on the telescopic rod of the electromagnet. The pawl and the ratchet teeth are mutually adapted.

[0019] The two sets of sliding plates are slidably installed on the sleeve. The two sets of sliding plates are connected to the telescopic rod of the telescopic cylinder. The telescopic cylinder is installed on the storage box.

[0020] A control panel is installed on the frame. The control system is arranged inside the control panel.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The buffer plate reduces vibration and cushions the tray, improving the stability of the tray. The downward impact force of the tray will push the buffer plate downward, and the buffer plate compresses the shock-absorbing spring. The shock-absorbing spring buffers the impact force of the tray to prevent the tray from being damaged or the parts on the tray from splashing, enhancing the stability of the tray. By adjusting the effective number of turns of the shock-absorbing spring, the shock-absorbing ability of the shock-absorbing spring for the tray can be adjusted to meet different usage scenarios. The more the effective number of turns of the shock-absorbing spring, the stronger the shock-absorbing ability of the shock-absorbing spring.

[0023] 2. Dust removal treatment for the tray to avoid adverse effects of dust on the tray. The control system opens the solenoid valve in the connecting pipeline between the dust removal chamber and the air slip ring inlet, and the negative pressure system extracts the air in the dust removal chamber outward, so that the dust around the tray enters the dust removal chamber through the adsorption holes and is discharged into the external atmosphere through the dust removal chamber, pipeline and air slip ring, preventing the tray from being contaminated with dust during transportation, thus causing problems such as transportation delay and obstruction, and avoiding adverse effects of dust on the parts in the tray.

[0024] 3. Automatic centering treatment for the tray to prevent the tray from shifting. The control system controls the operation of the telescopic cylinders on both sides and the coil to be connected to the circuit. The coil generates a magnetic field to convert the magnetorheological fluid from a liquid state to a solid state. The telescopic cylinders on both sides drive the sliding plates on both sides to move relatively, reducing the distance between the sliding plates on both sides. The sliding plates on both sides drive the conveyor belts and the load-carrying plates on both sides to move relatively, and the load-carrying plates on both sides clamp and position the tray, keeping the tray in a centered state and preventing the tray from shifting; the magnetorheological fluid changes from a liquid state to a solid state, preventing the conveyor belt from being bent and deformed during the clamping process, and further improving the clamping effect of the load-carrying plate.

The negative pressure system is installed on the frame 11. The load plate 141 is hollow inside. A number of negative pressure holes are opened on the load plate 141. All the negative pressure holes are communicated with the interior of the load plate 141. The interior of the load plate 141 is connected to the inlet of the air slip ring through a pipeline. Solenoid valves and flow meters are installed in the pipelines connected to the inlet of the air slip ring. The solenoid valves and the flow meters are both electrically connected to the control system.

[0040] There are telescopic shafts connected between the four corners of the receiving plate 15 and the storage bin 12. The telescopic shafts are of telescopic structure, and telescopic springs 151 are sleeved on the telescopic shafts. The telescopic springs 151 connect the receiving plate 15 and the storage bin 12, and both ends of the telescopic springs 151 are electrically connected to the control system.

Suction cups 155 are provided at the upper ends of the longitudinal rods 154. A longitudinal spring 156 is connected between the suction cups 155 and the transverse rods 152. Both ends of the transverse spring 153 and the longitudinal spring 156 are electrically connected to the control system. The suction cups 155 are connected to the negative pressure system through pipes.

[0041] Both groups of tray seats 16 are installed on the frame 11. Multiple positioning cylinders 161 are installed on the tray seats 16. The multiple positioning cylinders 161 are connected to the negative pressure system. Proximity switches are installed on the tray seats 16, and the proximity switches are electrically connected to the control system.

[0042] The feeding track includes a feeding motor 18 and a feeding guide rail 181. The feeding guide rail 181 is installed on the frame 11. Feeding rollers are rotatably installed at both ends of the feeding guide rail 181. A slider 182 is slidably installed on the feeding guide rail 181. The output shaft of the feeding motor 18 is connected to one of the feeding rollers. The feeding motor 18 is installed on the feeding guide rail 181. A transmission belt 183 is sleeved between the two groups of feeding rollers. The slider 182 is connected to the transmission belt 183. A support plate 184 is installed on the slider 182; a buffer plate 185 is installed above the support plate 184. Multiple guide columns are provided on the buffer plate 185. The multiple guide columns pass through the support plate 184, and a sliding connection is formed between the guide columns and the support plate 184;

[0043] An adjustment motor 19 is installed in the middle of the support plate 184. The output shaft of the adjustment motor 19 passes through the support plate 184 and is connected to a transmission shaft 191. An adjustment plate 192 is splined on the outside of the transmission shaft 191. A shock-absorbing spring 193 is installed on the outside of the adjustment plate 192. Two groups of extension plates 194 are provided on the outside of the adjustment plate 192. One group of extension plates 194 is higher than the other group of extension plates 194. The two groups of extension plates 194 are respectively inserted between adjacent turns of the shock-absorbing spring 193. The upper end of the shock-absorbing spring 193 is installed on the buffer plate 185. Another group of displacement sensors are installed on both groups of extension plates 194; a buffer shaft 195 is provided on the lower side of the adjustment plate 192. The buffer shaft 195 passes through the support plate 184. A number of one-way ratchet teeth are provided on the buffer shaft 195. An electromagnet 196 is installed on the support plate 184 on one side of the buffer shaft 195. A pawl 197 is installed on the telescopic rod of the electromagnet 196. The pawl 197 and the ratchet teeth are mutually adapted.

[0044] By adjusting the effective number of turns of the shock-absorbing spring 193, the shock-absorbing capacity of the shock-absorbing spring 193 for the material tray 17 can be adjusted to meet different usage scenarios. The effective number of turns refers to the number of turns of the shock-absorbing spring 193 between the buffer plate 185 and the extension plate 194. The more the effective number of turns of the shock-absorbing spring 193, the stronger the shock-absorbing capacity of the shock-absorbing spring 193;

[0045] The control system drives the transmission shaft 191 to rotate by adjusting the motor 19. The transmission shaft 191 drives the adjusting plate 192 to rotate. The adjusting plate 192 drives the extension plates 194 on both sides to rotate accordingly. Since the extension plates 194 on both sides are respectively inserted into the shock-absorbing spring 193 between adjacent turns, and there is a spline connection between the adjusting plate 192 and the transmission shaft 191, when the extension plate 194 rotates, it moves downward at the same time, increasing the effective number of turns of the shock-absorbing spring 193 between the buffer plate 185 and the extension plate 194, and strengthening the shock-absorbing capacity of the shock-absorbing spring 193. At the same time, the adjusting plate 192 drives the buffer shaft 195 to move downward, and the ratchet teeth on the buffer shaft 195 move downward accordingly;

[0046] When the extension plate 194 moves to the set position, the displacement sensor on the extension plate 194 feeds the displacement data back to the control system. The control system energizes the electromagnet 196. The electromagnet 196 is a push-pull electromagnet, and the telescopic rod is the component that reciprocates on the electromagnet 196. The telescopic rod on the electromagnet 196 pushes the pawl 197 to engage with the ratchet teeth, preventing the buffer shaft 195 from moving downward, and further preventing the extension plate 194 and the adjusting plate 192 from moving, thus realizing the adjustment of the buffer shock-absorbing capacity.

[0047] Working principle: The staff places the material tray 17 on the carrier plates 141 on the two sides of the conveyor belt 14. The carrier plates 141 on both sides support the material tray 17. Press the start button on the control panel 1, and the storage bin starts. The control system controls the operation of the telescopic cylinders 131 on both sides and connects the coil 144 to the circuit. The coil 144 generates a magnetic field to convert the magnetorheological fluid from a liquid state to a solid state. The telescopic cylinders 131 on both sides drive the sliding plates 13 on both sides to move relatively, reducing the distance between the two sliding plates 13. The sliding plates 13 on both sides drive the conveyor belts 14 and the carrier plates 141 on both sides to move relatively. The carrier plates 141 on both sides clamp and position the material tray 17, keeping the material tray 17 in a centered state and preventing the material tray 17 from shifting; the magnetorheological fluid changes from a liquid state to a solid state, preventing the conveyor belt 14 from bending and deforming during the clamping process, and further improving the clamping effect of the carrier plate 141.

[0048] After the tray 17 is clamped and positioned by the carrier plates 141 on both sides, the encoder in the telescopic cylinder 131 feeds the displacement data back to the control system. The control system opens the solenoid valve in the connecting pipe between the air slip ring inlet and the carrier plate 141. The control system extracts the air in the carrier plate 141 where the tray 17 is placed through the negative pressure system, so that the negative pressure holes generate negative pressure to adsorb the tray 17, preventing the tray 17 from shaking during the up and down movement;

[0049] After the negative pressure holes adsorb the tray 17, the negative pressure system feeds the pressure signal back to the control system. The control system cuts off the power supply of the coil 144. After the coil 144 loses the magnetic field, the magnetorheological fluid changes from solid state to liquid state; then, the control system drives the conveyor belts 14 on both sides to move downward through the rollers 142 on both sides, that is, the conveyor belt 14 on the left moves clockwise, and the conveyor belt 14 on the right moves counterclockwise, so that the conveyor belts 14 on both sides drive the tray 17 to move downward through the carrier plates 141 on both sides;

[0050] During the downward movement of the tray 17, the encoder in the roller 142 feeds the displacement data of the tray 17 back to the control system in real time. The control system opens the solenoid valve in the connecting pipe between the dust removal chamber and the air slip ring inlet. The negative pressure system extracts the air in the dust removal chamber outward, so that the dust around the tray 17 enters the dust removal chamber through the adsorption holes 145, and is discharged to the external atmosphere through the dust removal chamber, pipeline and air slip ring, preventing the tray 17 from being contaminated with dust during transportation, thus causing problems such as transportation delay and obstruction, and avoiding the adverse effects of dust on the parts in the tray 17.

[0051] When the tray 17 moves close to the receiving plate 15, the encoder inside the roller 142 feeds the displacement data on the tray 17 back to the control system. The control system energizes the telescopic spring 151. After the telescopic spring 151 is energized, each turn generates a magnetic field that attracts each other, and this magnetic field compresses the telescopic spring 151, making the overall telescopic spring 151 shorten. The telescopic spring 151 pulls the receiving plate 15 to move upward, and the receiving plate 15 drives the cross bar 152, longitudinal bar 154, suction cup 155, etc. to move upward, so that the suction cup 155 contacts the tray 17, and the suction cup 155 and the negative pressure system cooperate to generate negative pressure to adsorb the tray 17;

[0052] After the tray 17 is adsorbed by the suction cup 155, the negative pressure system feeds the pressure signal of the suction cup 155 back to the control system. The control system extracts the external air into the carrier plate 141 through the negative pressure system, so that the negative pressure holes release the tray 17. At this time, the tray 17 is adsorbed by the suction cup 155;

[0053] When the negative pressure hole releases the material tray 17, the negative pressure system feeds back the pressure signal of the negative pressure hole to the control system. The control system cuts off the power supply of the telescopic spring 151. Under the action of its own elastic force, the telescopic spring 151 gradually elongates. The telescopic spring 151 pushes the receiving plate 15 downward. The receiving plate 15 drives the material tray 17 to move downward through the suction cup 155.

[0054] When the receiving plate 15 drives the material tray 17 to move downward through the suction cup 155, the displacement sensor on the receiving plate 15 feeds back the displacement data of the material tray 17 to the control system. The control system energizes the longitudinal spring 156. The longitudinal spring 156 pulls the longitudinal rod 154 and the suction cup 155 downward. The suction cup 155 drives the material tray 17 to move downward so that the material tray 17 is located in the rectangular groove.

[0055] When the longitudinal spring 156 is energized for a set time, the material tray 17 will be located in the rectangular groove. At this time, the control system cooperates with the negative pressure system and the suction cup 155 to make the suction cup 155 not adsorb the material tray 17, and energizes the transverse spring 153. The transverse spring 153 pulls the transverse rod 152 to move away from the material tray 17. The transverse rod 152 drives the longitudinal rod 154 and the longitudinal spring 156 to move away from the material tray 17, so that there is no blockage directly below the rectangular groove. At this time, the material tray 17 falls downward onto the buffer plate 185 due to its own weight.

[0056] During the process of the material tray 17 falling onto the buffer plate 185, the downward impact force of the material tray 17 will push the buffer plate 185 downward. The buffer plate 185 compresses the shock-absorbing spring 193, and the shock-absorbing spring 193 buffers the impact force of the material tray 17 to prevent the material tray 17 from being damaged or the parts on the material tray 17 from splashing, and improves the stability of the material tray 17.

[0057] After the material tray 17 falls onto the buffer plate 185, the proximity switch on the material tray seat 16 directly below feeds back the displacement data of the material tray 17 to the control system. The control system extends and then retracts the positioning cylinder 161 to position the material tray 17 to prevent the position of the material tray 17 from deviating. Then, the feeding motor 18 drives the feeding roller to rotate. The feeding roller drives the conveyor belt 183 to move. The conveyor belt 183 pulls the slider 182 to move on the feeding guide rail 181. The slider 182 drives the support plate 184 to move. The support plate 184 drives the buffer plate 185 to move through the guide post. The buffer plate 185 drives the material tray 17 to move towards the other material tray seat 16, realizing the feeding of the material tray 17.
