DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a material tray turntable for an intelligent logistics system, such as Figures 1 to 7 As shown, it includes a carrier 1, a turntable 2 is provided on the top of the carrier 1, and the turntable 2 is a turntable on a rotating roller conveyor in the prior art. Both sides of the turntable 2 are set to arc surfaces, and side panels 3 are symmetrically fixedly installed on the top of the carrier 1. The side panels 3 are in contact with the arc surface of the turntable 2. Openings 4 are opened on both sides of the turntable 2, and a cross bar 5 is fixedly installed between the inner walls on both sides of the opening 4. A bracket 6 is rotatably sleeved on the cross bar 5, and torsion springs 7 are sleeved on both ends of the cross bar 5. The two ends of the torsion spring 7 are respectively fixedly connected to the bracket 6 and the cross bar 5, and the end of the bracket 6 away from the cross bar 5 is fixedly connected to a connecting rod 8. An iron sheet 9 is fixedly installed on the top of the bracket 6, and elastic cloth 10 is provided between the opposite sides of the two iron sheets 9 and the side away from the two iron sheets 9. The elastic cloth 10 between the sheets 9 is fixedly connected to the two iron sheets 9, one end of the elastic cloth 10 located on the side away from the two iron sheets 9 is fixedly connected to the iron sheet 9, and the other end is fixedly connected to the side of the bracket 6 close to the cross bar 5. The elastic cloth 10 connected to the bracket 6 passes through the mounting frame on which short guide rollers are installed on the turntable 2 and is fixedly connected to the mounting frame. A limiting component for limiting the bracket 6 is provided inside the turntable 2, and an anti-falling component for preventing goods from falling along the elastic cloth 10 is provided on the connecting rod 8. An arc-shaped inclined plate 29 is fixedly installed on the top of the opening 4, and inclined guide plates 28 are fixedly installed on both sides of the bottom wall of the turntable 2. In the initial state, the position of the elastic cloth 10 in the middle is below the cross bars 5 on both sides, so the two iron sheets 9 are in an inclined state.

[0028] When in use, after the goods enter the top of the turntable 2, the turntable 2 rotates 90 degrees. The rotation principle of the turntable 2 is consistent with the rotation principle of the turntable on the rotary roller conveyor in the prior art, which is the prior art and will not be repeated here. After rotating 90 degrees, the turntable 2 stops rotating, and then cooperates with the guide rollers on the turntable 2 to transport the goods. During the transportation process, if the packaging bag of the goods is accidentally damaged and the goods inside it fall into the inside of the turntable 2, the goods slide along the inclined elastic cloth 10 and the iron sheet 9 to the middle elastic cloth 10, so that the goods are gathered at the middle elastic cloth 10, so that no goods are located at the opening 4 and contact with the side plate 3, so that when the turntable 2 rotates, there will be no friction between the goods and the inner wall of the side plate 3 or continuous jamming causing the turntable 2 to vibrate, so that the entire turntable 2 can run smoothly and can stably transport the goods. When the turntable 2 rotates 90 degrees and stops, it is opened at this time. The opening 4 is located between the two side plates 3 and is not blocked by the side plates 3. When the goods leave the turntable 2, the restriction of the limiting component on the bracket 6 is cancelled, and the torsion spring 7 that has been torsionally deformed releases the force to rotate the bracket 6 upward. In this process, the anti-falling component can support the goods on the elastic cloth 10 in the middle to prevent the goods from falling and falling under the iron sheet 9 with the elastic cloth 10. As the bracket 6 rotates, the bracket 6 is finally tilted, and the position of the elastic cloth 10 in the middle is higher than the cross bars 5 on both sides. Under the action of gravity, the goods slide toward the opening 4 along the surface of the inclined iron sheet 9, and finally leave the inside of the turntable 2 from the opening 4, and the goods can be collected to complete the automatic cleaning and collection of the goods dropped in the turntable 2. Then the limiting component resumes the restriction on the bracket 6, so that the bracket 6 rotates downward, and the torsion spring 7 is torsionally deformed to generate a force, and finally the bracket 6 is reset.

[0029] like Figure 1 and Figure 4 As shown, the limiting component includes four electromagnets 11 fixedly connected to the bottom wall of the turntable 2. The electromagnet 11 is located below the bracket 6. The bracket 6 is made of iron. A controller 12 for controlling the electromagnet 11 is fixedly installed on the bottom wall of the turntable 2. The controller 13 is PLC controlled. A groove is provided on one side of the top of the turntable 2. A sensor 13 that cooperates with the controller 12 is provided in the groove. The sensor 13 is a photoelectric sensor.

[0030] When the goods leave the turntable 2, the sensor 13 detects the departure of the goods, and then cooperates with the controller 12 to pause the turntable 2 for 5S. At the same time, the controller 12 controls the energized electromagnet 11 to be powered off to make it lose its magnetism and lose the adsorption and fixation of the bracket 6. The torsion spring 7 that has been torsionally deformed releases its force to rotate the bracket 6 upward. After more than 5S, the controller 12 controls the electromagnet 11 to be powered on to make it magnetic, and then attracts the bracket 6 to make it rotate downward, and at the same time twists the torsion spring 7 to make it torsionally deform, and finally the bracket 6 is adsorbed and fixed to the electromagnet 11.

[0031] like Figure 6 As shown, the anti-falling assembly includes a baffle 14, a movable opening for the baffle 14 to pass through is opened on the connecting rod 8, the baffle 14 passes through the movable opening, a fixing plate 15 is fixedly installed on the bottom of the iron sheet 9, and a limiting rod 16 is equidistantly slidably inserted on the fixing plate 15, and the end of the limiting rod 16 close to the baffle 14 is fixedly connected to the baffle 14, the cross-section of the limiting rod 16 is T-shaped, and the outside of the limiting rod 16 is sleeved with a first spring 17, and the first spring 17 is located between the baffle 14 and the fixing plate 15, and the opposite sides of the two baffles 14 are set to be arc-shaped, and the opposite ends of the two baffles 14 are in conflict with each other.

[0032] When the bracket 6 rotates upward with the cross bar 5 as the fulcrum, the bracket 6 moves with the connecting rod 8 and the baffle 14. During the rotation, the distance between the two connecting rods 8 is shortened, so that the two baffles 14 are squeezed against each other. During the squeezing process, the baffles 14 compress the corresponding first springs 17 to deform and generate a force. When the bracket 6 rotates to a horizontal position, as the bracket 6 continues to rotate, the distance between the two connecting rods 8 becomes larger, and the compressed first spring 17 continuously releases the force to reset the baffle 14. When the bracket 6 stops rotating, the opposite ends of the two baffles 14 tilt upward, so that the middle part of the elastic cloth 10 in the middle tilts upward to help the goods slide down. During the whole process, the two baffles 14 always maintain contact, so as to block the goods and prevent the goods from falling and pulling the elastic cloth 10 in the middle to fall together, so as to avoid affecting the subsequent cleaning of the goods.

[0033] like Figure 5 and Figure 7 As shown, a blocking rod 18 is fixedly installed on the inner wall of the turntable 2 and above the bracket 6, and an anti-pinch component for preventing goods from being pinched between the blocking rod 18 and the iron sheet 9 is provided on the top of the iron sheet 9.

[0034] When the fallen cargo is fine particles, at this time, after the bracket 6 stops rotating upward, the iron sheet 9 conflicts with the baffle 18. At this time, some particles have not separated from the iron sheet 9 and the elastic cloth 10. At this time, the controller 12 controls the intermittent power on and power off of the electromagnet 11. When the electromagnet 11 is energized, it has magnetism, which attracts the bracket 6 and makes the bracket 6 rotate downward, thereby twisting the torsion spring 7. When the bracket 6 has not rotated to a horizontal state, the electromagnet 11 is powered off and loses its magnetism. At this time, the torsion spring 7 releases its force and causes the bracket 6 to rotate upward rapidly, causing the iron sheet 9 to move and collide with the baffle 18 to generate vibration. Subsequently, the intermittent power on and power off of the electromagnet 11 causes the iron sheet 9 to vibrate continuously, thereby causing the particles on its surface to vibrate continuously, helping these particles to leave the iron sheet 9 and the elastic cloth 10, thereby enabling a more thorough cleaning and collection of the particles.

[0035] like Figure 5 and Figure 7As shown, the anti-pinch assembly includes an arcuate shell 19 fixedly connected to the top of the iron sheet 9 and corresponding to the baffle rod 18. The arcuate shell 19 is sleeved on the outside of the baffle rod 18. A slope 20 is provided on one side of the arcuate shell 19 close to the middle elastic cloth 10, and a through opening is provided on the surface of the arcuate shell 19.

[0036] The setting of the inclined surface 20 ensures that the goods will not be stuck in the arc shell 19 when sliding along the surface of the iron sheet 9 toward the opening 4. The setting of the arc shell 19 makes it possible to close the bottom of the baffle 18, thereby preventing the goods from being located below the baffle 18 and getting stuck between the iron sheet 9 and the baffle 18 when the iron sheet 9 rises, thereby affecting the inclination of the iron sheet 9. This ensures that the iron sheet 9 can be in an inclined state, thereby ensuring that the goods can slide smoothly toward the opening 4.

[0037] like Figure 6 As shown, a cavity 21 is provided inside the crossbar 5 , and spray holes facing the inclined guide plate 28 are equidistantly provided outside the crossbar 5 . An air injection assembly for injecting air into the internal cavity 21 of the crossbar 5 is provided outside the crossbar 5 .

[0038] The inclined guide plate 28 can guide part of the goods falling from the elastic cloth 10 so that the goods can completely leave the turntable 2. When the bracket 6 rotates downward, the air injection component is cooperated to inject air into the cavity 21. After the air fills the cavity 21, it is sprayed out from the spray hole, so that the granular goods remaining on the top of the inclined guide plate 28 are blown, so that this part of the granular goods leave the inclined guide plate 28 and completely leave the turntable 2.

[0039] like Figure 6 As shown, the gas injection assembly includes a cylinder body 22 fixed on the bottom wall of the turntable 2, the cylinder body 22 corresponds to the cross bar 5, and the lower part of one side of the cylinder body 22 is connected to the cavity 21 through a hose 23. An air inlet is provided at the lower part of the side of the cylinder body 22 away from the hose 23, and a one-way valve 24 is provided inside the air inlet and the hose 23. A piston 25 is provided inside the cylinder body 22, and a push rod 27 is fixedly installed on the top of the piston 25. A second spring 26 is provided at the bottom of the piston 25, and the top of the push rod 27 extends to the outside of the cylinder body 22 and contacts with the bottom of the iron sheet 9.

[0040] When the bracket 6 rotates upward with the cross bar 5 as the fulcrum, the iron sheet 9 moves accordingly, and the compressed second spring 26 continuously releases the force to carry the piston 25 and the push rod 27 up, so that air is sucked into the cylinder body 22. At this time, the one-way valve 24 located in the air inlet hole is opened, and the one-way valve 24 located in the hose 23 is closed. At this time, the outside air enters the cylinder body 22 through the air inlet hole. When the bracket 6 descends, the iron sheet 9 squeezes the push rod 27 and the piston 25, so that the piston 25 descends and squeezes the air in the cylinder body 22 outward. At this time, the one-way valve 24 located in the air inlet hole is closed, and the one-way valve 24 located in the hose 23 is opened. The air enters the cavity 21 through the hose 23, fills the cavity 21, and then sprays outward through the spray hole, so that the particulate goods on the inclined guide plate 28 are blown to help the goods leave. The outer side of the inclined guide plate 28 matches the outer side shape of the turntable 2.

[0041] like Figure 3 and Figure 5 As shown, the stiffness constant of the torsion spring 7 is greater than the stiffness constant of the first spring 17 .

[0042] Working principle: when in use, after the goods enter the top of the turntable 2, the turntable 2 rotates 90 degrees. The rotation principle of the turntable 2 is consistent with the rotation principle of the turntable on the rotary roller conveyor in the prior art. It is the prior art and will not be described in detail here. After rotating 90 degrees, the turntable 2 stops rotating, and then cooperates with the guide rollers on the turntable 2 to transport the goods. In the process of transportation, if the packaging bag of the goods is accidentally damaged and the goods inside it fall into the turntable 2, the goods slide along the inclined elastic cloth 10 and the iron sheet 9 to the middle elastic cloth 10, so that the goods gather at the middle elastic cloth 10, so that no goods are located at the opening 4 and contact with the side plate 3, so that when the turntable 2 rotates, it will not The goods rub against the inner wall of the side plate 3 or are constantly stuck, causing the turntable 2 to vibrate, so that the entire turntable 2 can run smoothly and transport the goods stably. When the turntable 2 rotates 90 degrees and stops, the opening 4 is located between the two side plates 3 and is not blocked by the side plates 3. When the goods leave the turntable 2, the sensor 13 detects the departure of the goods, and then cooperates with the controller 12 to pause the turntable 2 for 5S. At the same time, the controller 12 controls the energized electromagnet 11 to be de-energized to make it lose its magnetism and lose the adsorption and fixation of the bracket 6. The torsion spring 7 that is torsionally deformed releases its force to rotate the bracket 6 upward. When the bracket 6 rotates upward with the cross bar 5 as the fulcrum, the bracket 6, the connecting rod 8 and the baffle 14 rotate upward. During the rotation, the distance between the two connecting rods 8 is shortened, so that the two baffles 14 are squeezed against each other. During the squeezing process, the baffles 14 compress the first springs 17 corresponding to each other to deform and generate a force. When the bracket 6 rotates to the horizontal position, as the bracket 6 continues to rotate, the distance between the two connecting rods 8 becomes larger, and the compressed first springs 17 continuously release the force to reset the baffle 14. When the bracket 6 stops rotating, the opposite ends of the two baffles 14 tilt upward, so that the middle part of the elastic cloth 10 in the middle tilts upward to help the goods slide down. During the whole process, the two baffles 14 always keep in contact with each other, so as to block the goods and prevent the goods from sliding down. The falling pulls the elastic cloth 10 in the middle to fall together to avoid affecting the cleaning of subsequent goods. As the bracket 6 rotates, the bracket 6 is finally tilted, and the position of the elastic cloth 10 in the middle is higher than the cross bars 5 on both sides. Under the action of gravity, the goods slide along the surface of the inclined iron sheet 9 to the opening 4, and finally leave the inside of the turntable 2 from the opening 4. The goods can be collected, and the automatic cleaning and collection of the goods dropped in the turntable 2 is completed. After more than 5S, the controller 12 controls the electromagnet 11 to energize it to make it magnetic, and then attracts the bracket 6 to rotate downward, and twists the torsion spring 7 to twist it. Finally, the bracket 6 is adsorbed and fixed to the electromagnet 11, and finally the bracket 6 is reset;

[0043] When the dropped cargo is fine particles, at this time, after the bracket 6 stops rotating upward, the iron sheet 9 conflicts with the blocking rod 18. At this time, some particles have not separated from the iron sheet 9 and the elastic cloth 10. At this time, the controller 12 controls the electromagnet 11 to be intermittently powered on and off. When the electromagnet 11 is powered on, it has magnetism, which attracts the bracket 6 and makes the bracket 6 rotate downward, thereby twisting the torsion spring 7. When the bracket 6 has not rotated to the horizontal state, the electromagnet 11 is powered off and loses its magnetism. At this time, the torsion spring 7 releases its force and causes the bracket 6 to rotate upward quickly, causing the iron sheet 9 to move and collide with the blocking rod 18 to generate vibration, and then the electromagnet 11 is intermittently powered on and off. The power is turned on and off, so that the iron sheet 9 is constantly vibrating, so that the particles on its surface are constantly vibrating, which helps these particles leave the iron sheet 9 and the elastic cloth 10, so that the particles can be cleaned and collected more thoroughly. The setting of the inclined surface 20 ensures that when the goods slide along the surface of the iron sheet 9 to the opening 4, they will not be stuck at the arc shell 19. The arc shell 19 can be set to close the bottom of the baffle 18, so as to prevent the goods from being located under the baffle 18 and being stuck between the iron sheet 9 and the baffle 18 when the iron sheet 9 rises, affecting the inclination of the iron sheet 9, so as to ensure that the iron sheet 9 can be in an inclined state, and thus ensure that the goods can slide smoothly to the opening 4;

[0044] When the bracket 6 rotates upward with the cross bar 5 as the fulcrum, the iron sheet 9 moves accordingly, and the compressed second spring 26 continuously releases the force to carry the piston 25 and the push rod 27 upward, so that air is sucked into the cylinder body 22. At this time, the one-way valve 24 located in the air inlet hole is opened, and the one-way valve 24 located in the hose 23 is closed. At this time, the outside air enters the cylinder body 22 through the air inlet hole. When the bracket 6 descends, the iron sheet 9 squeezes the push rod 27 and the piston 25, so that the piston 25 descends and squeezes the air in the cylinder body 22 outward. At this time, the one-way valve 24 located in the air inlet hole is closed, and the one-way valve 24 located in the hose 23 is opened. The air enters the cavity 21 through the hose 23, fills the cavity 21, and then sprays outward through the spray hole, so that the granular goods on the inclined guide plate 28 are blown, helping the goods to leave, thereby improving the collection effect of granular goods.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
