Abstract
Description
Technical Field
[0001] This invention relates to the field of sorting equipment, and in particular to a flip-top sorting device, its sorting method, and a flip-top sorting system. Background Technology
[0002] Patent document US5054601A discloses a usable flip-top sorting machine.
[0003] The tilting sorting component in the tilting sorting machine moves along the track, and the tilting of the tilting sorting component needs to be tilted left and right for sorting. Therefore, there needs to be a certain gap between the tilting and the track. At the same time, after the tilting is tilted, it needs to be restored to the upright state by the reset component at a predetermined position. Therefore, before the tilting is reset, there is a risk that the goods will fall into the internal parts of the equipment and get stuck. Summary of the Invention
[0004] The purpose of this invention is to solve the above-mentioned problems existing in the prior art and to provide a flip-top sorting device, its sorting method and flip-top sorting system.
[0005] The objective of this invention is achieved through the following technical solution:
[0006] A tilting sorting device includes a track and a set of tilting sorting components that move along the track. The track includes an inner rail and an outer rail. Each tilting sorting component includes a frame and a base frame mounted on the frame, with the tilting components mounted on the base frame.
[0007] An inner protective cover is provided on the inner rail, and an outer protective cover is provided on the outer rail; the inner and outer protective covers do not interfere with the tilting and turning of the tilting assembly.
[0008] The base frame is provided with a shielding plate surrounding its outer perimeter. The shielding plate does not interfere with the tilting and tilting of the tilting assembly and is shielded between the upper sides of the inner and outer protective covers.
[0009] Preferably, the shielding plate includes an upper plate and a lower plate axially distributed along the axis of rotation around which the flipping assembly rotates, and the upper plate of the shielding plate of each flipping sorting assembly partially overlaps with the lower plate of the shielding plate of another flipping sorting assembly connected to it.
[0010] Preferably, the inner and outer protective covers include a sliding ramp that allows goods to fall from them.
[0011] Preferably, the flip-top sorting device further includes a distance sensor for detecting the slip position of goods that slip from the straight extension of the inner and outer protective covers.
[0012] Preferably, a detection sensor is provided at a predetermined position on the track, upstream of the reset assembly at the track, for detecting whether there are goods on the shielding plate between adjacent flip-top sorting assemblies.
[0013] Preferably, a processing device for dropping goods off the shield is provided at the track downstream of the detection sensor.
[0014] Preferably, the processing device is located at the upstream end of the turning section of the track.
[0015] A flip-top sorting system, including any of the flip-top sorting devices described above.
[0016] The sorting method of the flip-top sorting device includes the following steps:
[0017] During the movement of the tilting sorting assembly along the track, the signal from the distance measuring sensor is acquired. When the distance measured by the distance measuring sensor is determined, the falling position of the goods is determined based on the distance measured by the distance measuring sensor.
[0018] The sorting method of the flip-top sorting device includes the following steps:
[0019] As the tipping sorting assembly moves along the track, a detection sensor detects whether there are goods on the shielding plate between adjacent tipping sorting assemblies.
[0020] When it is determined that there are goods on the shielding plate between adjacent tipping sorting components, the movement of the tipping sorting components is stopped and an alarm is triggered.
[0021] The sorting method of the flip-top sorting device includes the following steps:
[0022] As the tipping sorting assembly moves along the track, a detection sensor detects whether there are goods on the shielding plate between two adjacent tipping sorting assemblies.
[0023] When it is determined that there is cargo on the shield between two adjacent flip-top sorting components, and when it is determined that the cargo on the shield has moved to the processing device, the processing device is activated to cause the cargo to fall off the shield.
[0024] The advantages of the technical solution of this invention are mainly reflected in:
[0025] The present invention features a shielding plate on the tilting sorting assembly, which works in conjunction with the inner and outer protective covers on the inner and outer rails to cover the gap between the inner and outer rails. This ensures that even if goods fall off the tilting sorting assembly, they can slide off the inner and outer protective covers or be blocked by the shielding plate between the two tilting sorting assemblies, preventing them from entering the space between the inner and outer rails and effectively reducing the risk of jamming.
[0026] This invention, by setting up a detection component, can detect in a timely manner whether there are goods on the shielding plate, thereby issuing an alarm or processing them through a processing device, effectively preventing the goods at the shielding plate from being crushed or affected by the flip-top sorting component during sorting or resetting.
[0027] This invention places the processing device upstream of the turning section, enabling timely processing when goods are detected on the shield, thus preventing goods from slipping off the shield during the turning section and affecting the safety of the goods and subsequent processing.
[0028] This invention, by setting up a ranging sensor, can effectively detect the sliding position of goods that have slipped from the inner and outer protective covers, accurately determine the compartment into which the slipped goods have entered, and thus provide targeted reminders for manual handling to ensure the accuracy of sorting.
[0029] This invention, through the positional design of the ranging sensor and the processing device, enables the ranging sensor to determine the processing result of the processing device, thereby allowing timely feedback on situations where the processing device fails to effectively handle the problem. This not only expands the role of the ranging sensor but also improves the reliability of the processing. Attached Figure Description

[0040] Example 1
[0041] The flip-top sorting device disclosed in this invention will now be described in conjunction with the accompanying drawings. Figure 1 As shown, it includes a track 100 and a set of tilting sorting assemblies 200 that move along the track 100.
[0042] As attached Figure 1 - Appendix Figure 3 As shown, the track 100 includes an inner track 110 and an outer track 120 arranged concentrically, which are mounted on the track support 130. The shapes of the inner track 110 and the outer track 120 can be designed as needed, such as concentric waist-shaped or rounded rectangles, etc., which are not limited here. Furthermore, the inner track 110 and the outer track 120 include wheel grooves 140 with a C-shaped cross-section for the movement of the vehicle's wheels, and a baffle 150 extending downwards is vertically arranged on the inner side of the bottom plate of the wheel groove 140 for the movement of the guide wheels on the vehicle frame.
[0043] As attached Figure 1 Appendix Figure 3As shown, an inner protective cover 160 is provided above the inner rail 110, and an outer protective cover 170 is provided on the outer rail 120. The inner and outer protective covers are fixed to the profile 180 on the outside of the rail via connectors 190. The profile is fixed to the column on the outside of the rail support. The inner protective cover 160 and the outer protective cover 170 do not interfere with the tilting of the tilting assembly 230 of the tilting sorting assembly 200. The inner protective cover 160 and the outer protective cover 170 are symmetrically arranged, and... Both the inner protective cover 160 and the outer protective cover 170 include a vertical plate 101 and an inclined plate 102 connected above the vertical plate 101 and inclined upward toward the inner side of the vertical plate 101. The outer surface of the inclined plate 102 is a sliding slope for the goods 300 to fall from it. At the same time, a bent plate 103 inclined inward and upward may be connected to the upper side of the inclined plate 102. The vertical plate 101, the inclined plate 102 and the bent plate 103 may be formed by stamping sheet metal.
[0044] The specific structure of the flip-top sorting component 200 can be referred to the structure disclosed in the patent document with application publication number CN118618814A.
[0045] For details, see attached. Figure 4 As shown, the flip-top sorting assembly 200 includes a frame 210 that moves along the inner rail 110 and the outer rail 120, and a base frame 220 disposed on the frame 210. A flip-top assembly 230 that can rotate relative to the base frame 220 is disposed on the base frame 220.
[0046] Unlike existing flip-top sorting components, this invention, as shown in the appendix... Figure 3 - Appendix Figure 5 As shown, a shielding plate 240 is provided on the base frame 220 and surrounds its outer perimeter. The shielding plate 240 does not interfere with the tilting of the tilting assembly 230 and is shielded between the upper sides of the inner cover 160 and the outer cover 170. That is, the shielding plate 240 is higher than the inner cover 160 and the outer cover 170 but close to the upper sides of the inner cover 160 and the outer cover 170. At the same time, the two sides of the shielding plate 240 extend close to the upper sides of the inner cover 160 and the outer cover 170 or extend to the outside of the upper sides of the inner cover 160 and the outer cover 170.
[0047] As attached Figure 4 Appendix Figure 5As shown, the shielding plate 240 is connected to the base frame 220 via brackets 250 located outside the two side plates 221 of the base frame 220, and both ends of the shielding plate 240 extend to the sides of the tray 231 of the tilting assembly. The shielding plate 240 includes an upper plate 241 and a lower plate 242 axially distributed along the axis of rotation around which the tilting assembly 230 rotates. The shielding plate 240 can be machined from a single sheet. The length of the lower plate 242 is approximately equal to the distance the tray 231 of the tilting assembly 230 extends axially along the axis of rotation, and the lower plate 242 is provided with clearance holes 243 to avoid interference with the locking assembly 270, which cooperates with the limiting rod 260, as it rotates with the tilting assembly 230. When the tilting assembly 230 is in the upright position, the top height of the lower plate 242 is approximately equal to the top height of the tilting drive wheels 272 on both sides of the locking frame 271 of the locking assembly 270. The distance by which the upper plate 241 extends along the axial direction of the rotating shaft is significantly less than the length of the lower plate 242.
[0048] As attached Figure 6 As shown, when multiple flip-top sorting components 200 are connected in sequence, the upper plate 241 of the shielding plate 240 of each flip-top sorting component 200 partially overlaps with the lower plate 242 of the shielding plate 240 of the other flip-top sorting component 200 connected to it. Thus, the shielding plate 240 can effectively cover the gap between the two flip-top sorting components 200, and at the same time, it can effectively shield the flip-top sorting component 200 when it turns in the turning section of the track 100 and avoid affecting the turning.
[0049] As attached Figure 4 As shown, in order to reduce the risk of goods falling from the two long sides of the pallet other than the two sorting sides, wing plates 233 are respectively provided on the two long sides. When the pallet is upright, the wing plates 233 are horizontally positioned, and the outer side of the wing plates 233 is toothed.
[0050] When goods 300 fall from the tipping assembly 230 onto the shielding plate 240, goods 300 can usually slide off the outer cover 170 or the inner cover 160, thus sliding into the sorting slots on both sides of the track. If goods 300 sliding off the outer cover 170 and the inner cover 160 are not detected, missorting will occur. Therefore, in order to promptly detect goods 300 sliding off the outer cover 170 and the inner cover 160 and to determine as much as possible the sorting slots that goods 300 have slid into, as shown in the attached... Figure 3As shown, the tilting sorting device also includes a distance sensor 400 for detecting the sliding position of goods 300 that slide off the straight extensions of the inner cover 160 and the outer cover 170. The distance sensor 400 is, for example, a laser distance sensor, and its specific measurement range can be determined according to the length of the straight extensions of the inner cover 160 and the outer cover 170, which is not limited here. Furthermore, there are multiple distance sensors 400, the number of which is the same as the number of straight extensions of the inner cover 160 and the outer cover 170. For example, in a waist-shaped track, the inner cover 160 and the outer cover 170 each have two straight extensions and a turning section connecting the two ends of the two straight extensions, resulting in a total of four straight extensions. Four distance sensors 400 are correspondingly arranged on each straight extension, with each distance sensor 400 located at the end of a straight extension and outside the inclined plate 102 of the straight extension. Simultaneously, the detection sensor 400 is located below the tilted sorting pallet 231 so as not to affect the movement of the tilted pallet. When no goods 300 slide off the inner cover 160 and outer cover 170, the detection result of the ranging sensor 400 remains unchanged. When goods 300 slide off the inner cover 160 or outer cover 170, the distance measured by the ranging sensor 400 changes. This can confirm the presence of goods 300 sliding off, and can also determine the sorting compartment where the goods 300 might fall based on the real-time measured distance and the distance between each sorting compartment and the ranging sensor 400. This allows the indicator light at the sorting compartment where the goods 300 might fall to illuminate and / or signal. The system uses audible and visual alarms to alert manual personnel to troubleshoot anomalies. During manual troubleshooting, the system can switch the working status of these sorting slots to locked, making sorting impossible. At this time, the tilting sorting component 200, which contains the goods 300 that need to be sorted into these sorting slots, will stop sorting the goods 300 into these sorting slots until the anomaly is resolved. When the manual personnel issue an unlock command for the sorting slots, the working status of these sorting slots will switch to unlocked, sortable. Only then can the tilting sorting component 200 continue to sort the goods 300 that need to be sorted into these sorting slots into the corresponding sorting slots.
[0051] Of course, when the cargo 300 falls from the tipping assembly 230 onto the shielding plate 240 without sliding off the inner and outer protective covers, as shown in the attached... Figure 6 As shown, goods 300 may remain on the shielding plate 240 between adjacent tipping sorting components 200. If such goods 300 are not detected, when the tilted tipping sorting component 200 moves to the reset component 500 to restore its upright position, or when the tipping sorting component 200 where the fallen goods 300 was originally located starts sorting, interference between the goods 300 and the pallet 231 of the tipping component 230 is likely to occur. Therefore, it is necessary to detect the goods 300 on the shielding plate 240 in a timely manner. Correspondingly, as shown in the attached... Figure 3 Appendix Figure 6 As shown, a detection sensor 600 is provided at a predetermined position on the track 100, upstream of the reset assembly 500, for detecting whether there is cargo 300 on the shielding plate 240 between adjacent tilting sorting assemblies 200. The detection sensor 600 can be, for example, a known through-beam sensor, proximity switch, or specular reflection sensor, etc., depending on the specific requirements. Furthermore, the specific position and number of the detection sensors 600 can be designed as needed. For example, a detection sensor 600 can be placed at intervals above and close to the upper plate 241 of the shielding plate 240, while the detection sensor 600 is located below the inclined tray 231, thereby avoiding interference from the tilting assembly's rotation on the detection.
[0052] Furthermore, to avoid interference from the tilting frame 232 of the tilting assembly 230 of the tilting sorting trolley, the real-time position of the pallet sorting trolley can be determined using a known trolley position tracking method. This allows for the determination of whether the object passing through each detection sensor 600 is the tilting frame 232 or the gap between two tilting frames 232. The corresponding technology is known and is not limited here. When it is determined that the gap between two tilting frames 232 passes through one of the detection sensors 600, the detection sensor 600 is continuously triggered, thus confirming the presence of goods on the shielding plate 240 corresponding to the gap. Furthermore, when any of the detection sensors 600 detects goods on the shielding plate 240, the movement of the tilting sorting assembly 200 along the track 100 can be stopped. After the tilting sorting assembly 200 stops, the goods on the shielding plate 240 are manually removed before operation resumes.
[0053] Even better, to avoid the efficiency loss, increased labor costs, and energy consumption caused by the sorting loop formed by the flip-top sorting components stopping for manual processing, as shown in the attached... Figure 1 Appendix Figure 2As shown, a processing device 700 for causing the cargo 300 to fall off the shield 240 can be provided at the track 100 downstream of the detection sensor 600. The processing device 700 can be, for example, a jetting device capable of blowing air onto the cargo 300 on the shield 240. The jetting device can blow the cargo 300 off the shield 240 by blowing a high-speed airflow onto it. Alternatively, the processing device 700 can be a pushing device, which can be an electric push rod. The front end of the telescopic rod of the electric push rod can be provided with a soft pad to reduce the impact during pushing. When it is determined that there is cargo 300 on the shield 240, and the shield 240 containing the cargo 300 moves to the pushing device, the telescopic rod of the electric push rod quickly extends and then returns to its original position. When the telescopic rod extends, the soft pad at the front end of the telescopic rod pushes the cargo 300 off the shield 240.
[0054] Furthermore, when using a pushing device for processing, the movement speed of the tilting sorting component along the track can be appropriately slowed down to avoid interference between the movement of the pushing device and the movement of the tilting sorting component. After processing, the tilting sorting component is restored to its normal movement speed. Of course, if the movement speed of the tilting sorting component itself is relatively slow, there is no need to slow it down during processing.
[0055] Furthermore, an abnormality handling compartment 710 is provided on the side of the track 100 opposite to the handling device 700 to receive the goods 300 blown down or pushed down by the handling device 700.
[0056] The location of the processing device 700 can be designed as needed; preferably, as shown in the attached figure... Figure 1 As shown, the processing device 700 is located at the upstream end of the turning section of the track 100. This location is chosen because goods 300 on the shielding plate 240 may slip off the shielding plate 240 due to centrifugal force when moving to the turning section. Since there are usually no sorting slots on the outer side of the turning section, there is a risk that goods 300 may fall and be damaged from the tilting sorting device. Even if the goods 300 are not damaged, they may be scattered, making centralized collection difficult. Therefore, processing the goods 300 on the shielding plate 240 before they move to the turning section effectively prevents them from slipping off the shielding plate during the turning section.
[0057] Of course, the number of processing devices 700 can be configured according to the length of each straight segment of the flip-top sorting device, and even one processing device 700 can be configured downstream of each detection sensor 600.
[0058] Furthermore, the distance sensor 400 can determine whether the goods on the corresponding shield 240 fall off the shield 240 after the processing device 700 is activated. Specifically, this is determined based on the signals from the distance sensors distributed on both sides of the tilting sorting assembly 200. When one of the processing devices 700 is processing, the distance sensor 400 on the other side of the track determines whether the measured distance changes and whether the changed distance value is within the corresponding range. The corresponding range is the theoretical distance range between the goods processed by the processing device 700 and the distance sensor when the goods slide off. If yes, it is determined that the goods 300 have fallen off the shield; otherwise, it is determined that the goods 300 are still on the shield 240. At this time, the tilting sorting device can be stopped and an alarm can be triggered. Of course, in another embodiment, a verification sensor located downstream of the processing device 700 may also be provided at the track 100, and the verification sensor is located upstream of the reset component 500 provided at the track 100. The verification sensor determines whether there is still cargo 300 on the shielding plate 240 after processing by the processing device 700.
[0059] Example 2

Similar to existing technologies, the tipping sorting system also includes a top packaging area 800 located on the side of the track 100 and compartment areas 900 located on both sides of the track 100. A barcode scanning device 001 is provided downstream of the top packaging area 800 and upstream of the compartment areas 900. Their specific structures are the same as those in existing technologies and will not be described in detail here.
[0061] Example 3
[0062] This embodiment discloses a sorting method for a flip-top sorting device, including the following steps:
[0063] During the movement of the flip-top sorting assembly 200 along the track 100, the signal from the distance measuring sensor 400 is acquired, and the falling position of the goods 300 is determined based on the distance measured by the distance measuring sensor 400.

[0065] This embodiment discloses a sorting method for a flip-top sorting device, including the following steps:
[0066] During the movement of the flip-top sorting assembly 200 along the track 100, the detection sensor 600 detects whether there is any goods 300 on the shielding plate 240 between adjacent flip-top sorting assemblies 200.
[0067] When it is determined that there is cargo 300 on the shielding plate 240 between adjacent flip-top sorting components 200, the movement of the flip-top sorting component 200 is stopped and an alarm is triggered.
[0068] Example 5
[0069] This embodiment discloses a sorting method for a flip-top sorting device, including the following steps:
[0070] During the movement of the flip-top sorting assembly 200 along the track 100, the detection sensor 600 detects whether there is any goods 300 on the shielding plate 240 between two adjacent flip-top sorting assemblies 200.
[0071] When it is determined that there is a cargo 300 on the shielding plate 240 between two adjacent flip-top sorting components 200, and when it is determined that the cargo 300 on the shielding plate 240 has moved to the processing device 700, the processing device 700 is activated to make the cargo 300 fall off the shielding plate 240.
