Description

Technical Field

[0001] The invention relates to logistics sorting equipment, in particular to a bidirectional flap trolley, a flap type sorting line and a flap type sorting system. Background Art

[0002] Sorting is the operation of stacking items by category and in the order of entry and exit. Sorting is to improve delivery and support delivery preparation work. It is an inevitable extension of different distribution companies competing and improving their own economic benefits during delivery. Therefore, it can also be said that sorting is an inevitable requirement for delivery to develop into a higher form.

[0003] The sorting and conveying system is a material handling system that classifies random and differently oriented items according to certain requirements. With the rapid development of e-commerce, the logistics industry has also developed rapidly. Various automatic and semi-automatic logistics sorting systems and equipment have been developed and applied to actual sorting operations. Among them, the flip-plate sorting equipment uses a flip plate that is tilted at a certain angle at the sorting position to unload the items on it into the sorting port or other sorting equipment.

[0004] Known flip-plate sorting equipment, such as the Chinese patent with application number "2017207460700" and patent name "Flip-plate mechanism and sorting robot", and the Chinese patent with application number "2016200065693" and patent name "Sorting robot", both reveal a mechanism in which the flip-plate is driven by a power device to tilt to one side.

[0005] However, their flaps can only tilt in one direction, so they can only unload in one direction. When unloading, in order to ensure that the items can be accurately sorted to the location to be sorted, the trolley must stop at a certain position before the power equipment can be started to turn the flap, which is not conducive to improving the sorting rate and efficiency.

[0006] Moreover, their flipping plates are driven by independent driving devices and each sorting machine has an independent wheel driving structure. Although the integration of a single device is improved, the corresponding equipment cost is also increased.

[0007] At the same time, within the limited scope of the site, since each flip-plate sorting robot requires a certain path to carry out sorting, this creates a contradiction between multiple paths and the size of the site, resulting in the inability to allow multiple flip-plate sorting robots to work at the same time, which is not conducive to meeting the sorting requirements of large quantities and multiple sorting paths. Summary of the invention

[0008] The purpose of the present invention is to solve the above problems existing in the prior art and to provide a two-way flap trolley, a flap type sorting line and a flap type sorting system.

[0016] Preferably, in the bidirectional flap trolley, a pair of baffles perpendicular to and parallel to the flap are provided on the top edge of the flap, and the baffles cooperate with the flap to form a slide groove, and the openings at both ends of the slide groove are located on both sides of the connecting shaft.

[0017] Preferably, in the bidirectional flip-up trolley, a pair of parallel guide top plates with the connecting axis as the axis of symmetry are provided in the bottom gap of the flip plate, and a slope inclined upward is formed at the bottom of the guide top plates, and the upper end of the slope is located at the front end of the bidirectional flip-up trolley.

[0018] Preferably, in the bidirectional flap trolley, a pair of leveling members for leveling the flap are further provided at the bottom of the flap.

[0019] A flap-type sorting line comprises any of the above-mentioned bidirectional flap trolleys, wherein the bidirectional flap trolley is slidably arranged on a track, and the bidirectional flap trolley is connected to a driving device that drives it to slide along the track, and also comprises a device that drives the flap to flip.

[0020] Preferably, in the flap-type sorting line, the bidirectional flap trolleys are multiple and are spaced apart on a circular track, and the multiple bidirectional flap trolleys are connected to the same driving device and move synchronously.

[0021] Preferably, in the flap type sorting line, the device for driving the flap to flip includes a forced discharge device, which includes at least one forced discharge slope arranged beside the track, and the height of the top plane of the forced discharge slope is higher than the bottom height of the leveling member in a horizontal state.

[0022] Preferably, in the flap-type sorting line, the forced discharge device further comprises a pair of first leveling slopes symmetrically distributed on both sides of the track, and the height of the top plane of the first leveling slope is equal to the bottom height of the leveling member in a horizontal state.

[0023] Preferably, in the flap-type sorting line, the device for driving the flap to flip includes an electrically driven lifting device, the lifting device includes a push rod, a rotating wheel is provided on the top of the push rod, under normal conditions, the rotating wheel is in a low position and has no contact with the flap; when unloading, the rotating wheel is in a high position, and the top height of the rotating wheel is higher than the height of the bottom plane of the guide top plate.

[0024] Preferably, the flap type sorting line further comprises a leveling device for leveling the flap from an inclined state after unloading.

[0025] Preferably, in the flip-plate sorting line, the leveling device includes at least a second leveling slope and a third leveling slope arranged on both sides of the track, the height of the top plane of the second leveling slope coincides with the bottom height of the leveling member in a horizontal state, the height of the top plane of the third leveling slope is higher than the height of the top plane of the second leveling slope, and its top plane is located behind the top plane of the second leveling slope.

[0026] Preferably, in the flap type sorting line, the leveling device comprises a pair of fourth leveling slopes symmetrically arranged on both sides of the track, and the top height of the fourth leveling slope is the same as the bottom height of the flap in a horizontal state.

[0027] The flip-plate sorting system includes any of the above-mentioned flip-plate sorting lines, and also includes a loading area, a detection device and a sorting grid area.

[0028] The advantages of the technical solution of the present invention are mainly reflected in:

[0029] This solution has an exquisite design and a simple structure. The flap can be flipped in two directions around its symmetry axis. The limit structure is used to stably maintain the flap in a horizontal and tilted state, thereby effectively realizing two-way selective sorting. In addition, the two-way sorting trolley of this solution eliminates the need for an independent power structure and a wheel drive structure for driving the flap to rotate. The overall structure is more streamlined and the equipment cost is lower. Since a purely mechanical structure is used, no complex electrical control structure is required, and production and maintenance are more convenient.

[0030] The present invention adopts a special lifting device design, which effectively cooperates with the two-way flap trolley to realize non-stop sorting, saves the parts loss and time lapse of equipment start and stop, and greatly improves the sorting efficiency and sorting accuracy.

[0031] In addition, one jacking device can work in conjunction with multiple two-way tipping trolleys, which is beneficial to reducing equipment costs. Multiple jacking devices are concentrated in one area, which also facilitates centralized management and maintenance.

[0032] The jacking device of the present invention has a simple structure, the jack is in an inclined state under normal conditions, the rotation angle during operation is small, and the two states are switched by whether the electromagnet is energized or not. The control is simple and the response speed is fast, thereby greatly improving the switching rate of the two states, which is beneficial to improving the running speed of the two-way flap trolley.

[0033] The bidirectional flap trolley of the present invention can be effectively combined with the track, and a chain drive method is adopted to realize synchronous operation of multiple trolleys. Combined with multiple lifting devices, multi-path sorting can be effectively realized under limited site conditions, avoiding the interference problem caused by the driving path of conventional trolleys, and having low requirements for the site. At the same time, multi-path synchronous sorting of multiple trolleys greatly improves the sorting efficiency.

[0034] The track of the present invention is a vertical ring and is arranged along a straight line, so it is convenient to arrange according to the site, which is conducive to saving space and can better cooperate with various other sorting equipment.

[0035] The present invention adds a forced discharge device and adopts a purely mechanical structure. In the absence of a lifting device, unloading can still be ensured. The structure is simpler and unloading methods are increased, thereby making the application of the sorting system more flexible.

[0036] By setting the height of the top plane of the strong discharge slope, the flap can have a larger inclination angle, thereby ensuring that the packages on the flap have greater unloading power and ensuring unloading.

[0037] The present invention adopts a purely mechanical leveling structure by cooperating the guide wheel and the wing plate with the leveling ramp. While effectively realizing the straightening of the flap, the risk of misoperation of electrical components can be prevented. In addition, compared with the electrical structure, the cost is lower and the processing is simpler. The setting of the double leveling structure also fully guarantees the reliability and effectiveness of the flap leveling. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The purpose, advantages and features of the present invention will be illustrated and explained by the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0045] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0046] The following is an explanation of the flip plate sorting line 100 disclosed by the present invention in conjunction with the accompanying drawings. Figure 1 As shown, it includes a two-way flip trolley 10, which is slidably arranged on a track 8, and the two-way flip trolley 10 is connected to a driving device 9 that drives it to slide along the track 8.

[0047] Among them, as attached Figure 2 As shown, the bidirectional flap trolley 10 includes a frame 1, and the frame 1 can be of various known structures. In the present embodiment, the frame 1 as a whole is two U-shaped frames 11 with a common bottom plate, and any two adjacent ones of their four side walls are vertical. The use of this structure can simplify the vehicle body structure to the greatest extent, facilitate processing, reduce costs, and is conducive to the miniaturization of the overall structure.

[0048] Two rollers 2 are respectively installed on the side plates of the U-shaped frame located at the bottom of the frame 1, so that the trolley can roll. Of course, in some other embodiments, the rollers are not necessary and can be omitted, or other structures can be used instead, such as balls protruding from the bottom of the frame. As long as the frame 1 can slide with the track, this is a known technology and will not be repeated here.

[0049] As attached Figure 2 , Attachment Figure 3 As shown, the upper pivot of the frame 1 is connected to a flap 3, and the flap 3 includes a rectangular flat plate 31, and the flat plate 31 is connected to the frame 1 through a pivot connection member 32 arranged at the bottom thereof, and the pivot connection member 32 has two parallel and inverted triangular connecting pieces 321, and a bearing 33 is arranged in the through hole of each connecting piece 321, and a bolt (connecting axis X) is connected to the inner ring of the bearing 33 and passes through a through hole on the side plate of the upper U-shaped frame of the frame 1 and is locked by a nut (not shown in the figure). The axis of the two connecting axes X connecting the flap 3 and the frame 1 is projected on the flap 3 as the symmetry axis of the flap, so that the flap 3 can rotate in two directions around the connecting axis X to realize two-way unloading, and,

[0050] In the loading state, the flap 3 is kept horizontal by the limiting mechanism 4;

[0051] In the unloading state, the flap 3 is kept inclined at a certain angle by the limiting mechanism 4 .

[0052] Specifically, as attached Figure 3 As shown, the limiting mechanism 4 includes a limiting pin 41 fixed on the frame 1 and a limiting member 42 that can be flipped synchronously with the flap 3. The limiting pin 41 is vertically fixed to the middle area of ​​a side plate of the upper U-shaped frame of the frame and extends into the groove of the U-shaped frame. The limiting member 42 is connected to the pivot connecting member 32 through an adapter frame 34. A semicircular limiting groove 421 and inclined limiting grooves 422 located on both sides and continuously distributed therewith are formed on its bottom plane. The inclined limiting groove 422 is in the shape of an inverted "J" inclined upward from the notch of the semicircular limiting groove 421, and the two inclined limiting grooves 422 are symmetrical.

[0053] When the limit pin 41 is clamped in the semicircular limit groove 421, the flap 3 is in a horizontal state; when the limit pin 41 is clamped at the bottom position of an inclined limit groove 422, the flap 3 is in an inclined state.

[0054] Further, as attached Figure 2 , Attachment Figure 3As shown, a pair of baffles 5 perpendicular to and parallel to the flap 3 are provided on the top edge of the flat plate 31 of the flap 3. The baffles 5 cooperate with the flap 3 to form a slide groove. The openings at both ends of the slide groove are located on both sides of the connecting axis X, so that the moving direction of the trolley is perpendicular to its unloading direction, thereby providing the possibility of unloading without stopping.

[0055] Of course, when actually unloading materials, the flap 3 can also be manually turned over for unloading as needed. At this time, the vehicle needs to be stopped for operation. Of course, other equipment can also be used to apply force to the flap to make it turn over for unloading.

[0056] When unloading materials without stopping, the following structure is adopted, as shown in the attached Figure 2 , Attachment Figure 3 As shown, a pair of parallel guide top plates 6 with the connection axis X as the axis of symmetry are provided in the bottom gap of the flap 3, the two guide top plates 6 are located on both sides of the track 8, and the guide top plates 6 are perpendicular to the flat plate 31 of the flap 3 and they are approximately inverted trapezoidal as a whole, a slope 61 is formed at the bottom of the guide top plates 6, the upper end of the slope 61 is located at the front end of the two-way flap trolley (in the description of the scheme, during the movement of the trolley, the part of the trolley that passes a certain position first is the front, and the part of the trolley that passes the position later is the rear, that is, the right side of the upper layer of the track is the front, and the left side is the rear, and the left side of the lower layer of the track is the front, and the right side is the rear) and has a rounded structure, and the lower end of the slope is connected with the bottom plane 62, as shown in the attached Figure 1 As shown, the two guide top plates 6 cooperate with the lifting device 20 in the flip-plate sorting line 100 to realize automatic unloading.

[0057] As attached Figure 1 As shown, the lifting device 20 is arranged beside the track 8, which can be a device or mechanism capable of lifting a certain stroke and tilting the flap 3, such as various cylinders, oil cylinders, etc. In this embodiment, as shown in the attached Figure 4 As shown, it preferably includes a support plate 203, the support plate 203 is L-shaped, and a push rod 201 is pivotally connected to a longer panel 2031, and the push rod 201 rotates around an axis Y connecting it and the panel 2031. The length of the push rod 201 is greater than the width of the panel 2031 and its upper end extends outside the top edge of the panel 2031. The top end of the push rod 201 is provided with a rotating wheel 202, and its lower end is connected to a power device 204 that drives it to rotate.

[0058] As attached Figure 5 As shown, in the first state, the power device 204 keeps the top rod 201 tilted, and the runner 202 thereon maintains a gap with the bottom of the guide top plate 6, and the runner 202 does not contact other parts of the two-way flap trolley;

[0059] As attached Figure 4 As shown, in the second state, the power device 204 keeps the top rod 201 vertical, and the top height of the rotating wheel 202 thereon is higher than the height of the bottom plane 62 of the guide top plate, when the trolley passes over the vertical top rod, the rotating wheel 202 can contact the slope 61 of a guide top plate 6 at the bottom of the flap 3, and when the rotating wheel 202 moves to the bottom plane 62, the flap 3 is flipped over and is in a tilted state.

[0060] The power device 204 may be of various feasible structures, such as a gas cylinder, an electric cylinder, an oil cylinder, etc. In this embodiment, the preferred structure is as shown in the attached figure. Figure 4 In the structure shown, the power device 204 includes a pull rod 2041, an electromagnetic pulling device 2042 and an elastic member 2043. One end of the pull rod 2041 is pivotally connected to a connecting member 2044 at the lower end of the top rod 201 and one end of the elastic member 2043, and the other end is pivotally connected to the electromagnetic pulling device 2042. The other end of the elastic member 2043 is fixed to a shorter panel 2032 of the support plate 203.

[0061] Furthermore, when the electromagnetic pulling device 2042 is powered off, the pulling force applied by the elastic member 2043 to the pull rod 2041 is greater than the pulling force applied by the electromagnetic pulling device 2041 to the pull rod 2041, and the top rod 201 remains in an inclined state;

[0062] When the electromagnetic pulling device 2042 is powered on, the pulling force applied by the electromagnetic pulling device 2042 to the pull rod 2041 is greater than the pulling force applied by the elastic member 2043 to the pull rod 2041, and the top rod remains in a vertical state.

[0063] The electromagnetic pulling device 2042 is an electromagnet. When the electromagnet is energized, the iron core therein is acted upon by the electromagnetic force to pull the pull rod 2041 toward the side where the electromagnet is located, and causes the elastic member 2043 to be deformed under force. When the electromagnet is de-energized, the iron core is no longer acted upon by the electromagnetic force, and the pull rod 2041 is pulled back to its original position under the reaction force of the elastic member 2043. The elastic member 2043 may be a tension spring, a spring, a shrapnel, or other component with a certain elastic deformation capability.

[0064] At the same time, the pulling force of the electromagnet can be set as needed, preferably adjusted between 37N-50N, and the main function of the elastic member 2043 in the above structure is to restore the top rod 201 from a vertical state to an inclined state when the electromagnetic pulling device 2042 is powered off. After the electromagnetic pulling device 2042 is powered off, it no longer applies pulling force to the pull rod 2041. Therefore, the pulling force of the elastic member only needs to be sufficient to pull the pull rod 2041 to reset, preferably between 5N-29N.

[0065] Furthermore, the other end of the elastic member 2043 is preferably connected to a position-adjustable tensioning bolt 205, and the tensioning bolt 205 is vertically arranged on the shorter panel 2032 of the support plate 203, so that the tension of the elastic member 2043 can be changed by adjusting the protruding length of the tensioning bolt 205 on the shorter panel of the support plate 203, thereby changing the magnitude of the pulling force applied to the elastic member when the electromagnetic pulling device 2042 is energized.

[0066] In addition, as attached Figure 4 As shown, the support plate 203 is also provided with a buffer stopper 206 for limiting the rotation angle of the push rod 201. The buffer stopper 206 includes a first stopper 2061 and a second stopper 2062.

[0067] The top rod 201 is in a vertical state and abuts against the first stopper 2061.

[0068] The push rod 201 abuts against the second stopper 2062 in the tilted state.

[0069] Correspondingly, gaskets 207 are respectively provided on the push rod 201 at the positions in contact with the first stop block 2061 and the second stop block 2062. During the rotation of the push rod 201, the first stop block 2061 and the second stop block 2062 can buffer the impact force of the push rod 201 during the swinging process and limit the push rod.

[0070] During operation, under normal conditions, the electromagnetic pulling device 2042 is powered off, and the top rod 201 remains in an inclined state under the pulling force of the elastic member 2043 . At this time, the bidirectional flip-plate trolley carrying items (packages, etc.) can pass over the top of the top rod 201 .

[0071] When the flap 3 needs to be tilted, firstly power on the electromagnetic pulling device 2042 of a lifting device 20 in front of the traveling direction of the bidirectional flap trolley 10 (the control of power on and off here can be realized by software programming, or by scanning codes, RFID radio frequency identification, sensors and other technologies to determine that the bidirectional flap trolley has arrived at the corresponding lifting device 20 for control. This is a known technology and will not be described in detail here). The electromagnet therein generates a magnetic force to pull the pull rod 2041, so that the pull rod 2041 rotates from a tilted state to a vertical state.

[0072] At this time, when the trolley passes through the vertical jacking device 20 of the jacking rod, the upper end of the slope 61 at the bottom of the guide top plate 6 first contacts the rotating wheel 202 on the jacking device 20, and as the trolley moves forward, the jacking rod 201 gradually applies an upward force to the bottom of the guide top plate 6, so that the corresponding end of the flap 3 has the power to flip upward to tilt it, and the rotation of the flap 3 causes the limit piece 42 to rotate relative to the limit pin 41, and causes the limit pin 41 to disengage from the semicircular limit groove 421 and gradually slide into the inclined limit groove 422 on the jacking side, until the rotating wheel 202 contacts the bottom plane 62 of the guide top plate 6, the jacking device 20 no longer applies an upward force to the flap 3, and at this time the limit pin 41 is located at the bottom position of the inclined limit groove 422, thereby achieving the locking of the flap 3.

[0073] After the trolley passes through the jacking device 20, if the position of the jacking device 20 no longer needs to unload materials, the electromagnetic pulling device 2042 in the jacking device 20 is powered off. At this time, the electromagnetic pulling device no longer applies pulling force to the pull rod 2041. Therefore, the pull rod 2041 is pulled toward the elastic member 2043 under the reaction force generated by the deformation of the elastic member 2043, thereby driving the jacking rod 201 to rotate in the opposite direction and reset to the inclined state.

[0074] Furthermore, in specific applications, the track 8 can be arranged according to different application environments, especially the size and shape of the space. The track 8 can be a non-closed and straight or non-straight line, or a closed line, and can be arranged in the horizontal direction or in a straight line as shown in the attached figure. Figure 1 As shown, it is arranged longitudinally (the track has an upper layer 81 and a lower layer 82), so that the application mode of the bidirectional flap trolley 10 can also be adjusted according to the specific environment.

[0075] For example, when the track 8 is a non-closed line, the bidirectional flap trolley 10 can reciprocate on the track 8, and correspondingly, the driving structure that drives its reciprocating movement can also be various feasible structures, such as a screw + motor structure.

[0076] When the track 8 is a closed circuit, preferably the track 8 is a longitudinally arranged annular track 8, the two-way flip trolley 10 can be multiple and slidably located on the track 8 in sequence, preferably they are arranged with equal gaps, and the multiple two-way flip trolleys 10 are driven by the same driving device 9, preferably, the driving device 9 includes a motor and two sprockets (not shown in the figure), the two sprockets are located at both ends of the track 8, one of the sprockets is connected to the motor, and the two sprockets are equipped with chains (not shown in the figure), the chains are connected to each two-way flip trolley 10, so that the chain is driven to rotate by the motor, and then all the two-way flip trolleys 10 are driven to slide along the track synchronously.

[0077] Moreover, the number of the lifting devices 20 can be set according to the actual sorting needs. For example, when there is one lifting device 20, the multiple two-way flip trolleys 10 can only unload materials to the same sorting port in one direction; when there are multiple lifting devices 20 and they are arranged side by side on the same side of the track 8, the two-way flip trolleys 10 can unload materials to multiple different sorting ports in one direction; when there are multiple lifting devices 20 and they are located on both sides of the track 8, the two-way flip trolleys can unload materials to multiple sorting ports on both sides of the track. Preferably, as shown in the attached figure Figure 1 As shown, there are multiple jacking devices 20, and they are symmetrically arranged on both sides of the upper layer 81 of the track 8, and the jacking devices 20 on the same side are arranged at equal intervals and the gap between adjacent jacking devices 20 is sufficient that when one of the two-way flip trolleys 10 contacts a jacking device 20, each pair of symmetrical jacking devices 20 corresponds to the position of a two-way flip trolley 10.

[0078] By matching the gaps between the trolleys and the lifting devices, it is possible to easily bind the data of multiple trolleys, parcels, and the lifting devices corresponding to the parcel routes, thereby improving the accuracy of sorting and reducing the difficulty of controlling the actions of multiple lifting devices, as well as improving the coordination and synchronization of simultaneous sorting by multiple trolleys, which is conducive to improving sorting efficiency and accuracy.

[0079] On the other hand, after unloading, the flap 3 needs to be restored to a horizontal state for loading, but since the flap 3 is restricted by the limiting mechanism 4 and cannot automatically restore to a horizontal state, it needs to be restored to a horizontal state manually or by corresponding equipment mechanisms.

[0080] Correspondingly, as attached Figure 2 As shown, a pair of leveling members 7 for leveling the flap 3 are also provided at the bottom of the flap 3. Figure 3 As shown in FIG. 1 , the leveling member 7 includes a support rod 71 fixed to the outer side wall of the guide top block 6 and perpendicular to the outer side wall thereof, and a guide wheel 72 rotatably disposed on the support rod 71, and the bottom of the guide wheel 72 is located above the middle point of the slope 61. Figure 1As shown, it also includes a leveling device 30 that cooperates with the guide wheel 72 to level the flap 3 after unloading from an inclined state, and is located in front of a pair of jacking devices 20 that the two-way flap trolley 10 passes last.

[0081] The leveling device 30 at least includes a second leveling slope 301 and a third leveling slope 302 arranged on both sides of the track 8, and their positions match the guide wheel 72 on the leveling member 7. The second leveling slope 301 includes an inclined wing 3011 inclined upward to the right and a slope top plane 3012, and the height of the slope top plane 3012 coincides with the bottom height of the leveling member 7 in a horizontal state, specifically, is the same as the bottom height of the guide wheel 72 of the leveling member 7. The third leveling slope 302 is, from one end to the other, a first inclined wing 3021 inclined upward to the right, a slope top plane 3022 and a second slope 3023 inclined downward to the right, and the height of the slope top plane 3022 is higher than the height of the slope top plane 3011 of the second leveling slope 301, and its slope top plane is located behind the slope top plane of the second leveling slope.

[0082] Of course, the specific structures of the second leveling slope and the third leveling slope may also adopt the method of the first leveling slope described below.

[0083] After unloading is completed, since the flap 3 is in an inclined state, the corresponding two guide wheels 72 are in a high and low state. When the guide wheels 72 pass through the second leveling slope 301 and the third leveling slope 302, they are adjusted to the same height under the support and restriction of the two leveling slopes, thereby flipping the trolley from an inclined state to a horizontal state.

[0084] Furthermore, during the flipping process of the flap 3, the limit member 42 rotates synchronously, and during the flipping process, it rotates relative to the limit pin 41, and causes the limit pin 41 to gradually slide from the inclined limit groove 422 into the semicircular limit groove 421, thereby limiting the horizontal state of the flap 3.

[0085] Of course, in actual application, in addition to the leveling method using the guide wheel 72 described above, the following wing plate leveling method may also be used, or the two may be organically combined, preferably the two methods are combined to ensure the reliability of leveling.

[0086] Specifically, if the flap 3 fails to be fully leveled when passing through the second leveling slope 301 and the third leveling slope 302, as shown in the attached Figure 1As shown, the leveling device 30 also includes a pair of fourth leveling slopes 303 symmetrically arranged on both sides of the track 8 and located in front of the second leveling slope 301 and the third leveling slope 302. The top edge of the fourth leveling slope 303 is arc-shaped, and the top height of the fourth leveling slope 303 is the same as the bottom height of the flap 3 in a horizontal state, specifically the same as the bottom surface height of the flat plate 31.

[0087] When the flap 3 passes through the first slope 301 and the second leveling slope 302 without being leveled, no matter which side it tilts to, when it passes through the fourth leveling slope 303, the wing plate of the flap 3 (the part extending outside the frame) will first contact the top arc of the fourth leveling slope 303 on one side, and gradually flip over under the action of its supporting force, until the flap 3 moves to the top position of the second leveling slope 302, the bottom of its two side wing plates respectively contact the top of a fourth leveling slope 303, so that the two side wing plates of the flap 3 are in the same height state to achieve leveling, and the limit member 42 flips synchronously with the flap 3. The limit member 42 rotates relative to the limit pin 41 during the flipping process, and makes the limit pin 41 gradually slide from the inclined limit groove 422 where it is located into the semicircular limit groove 421, thereby realizing the position limitation of the horizontal state of the flap 3.

[0088] On the other hand, considering that the lifting device 20 does not work due to equipment failure or failure to accurately obtain the route of a certain package, making it impossible to unload the material, if the package on the flap 3 is not unloaded at this time, it will affect the subsequent sorting. Correspondingly, the flap type sorting line also includes a forced discharge device 40 with a purely mechanical structure.

[0089] The forced discharge device 40 is placed between the lifting device 20 and the leveling device 30 that the two-way flip trolley 10 passes last, and it includes at least one forced discharge ramp 401. The position of the forced discharge ramp 401 matches the position of the guide wheel 72 on the two-way flip trolley 10, and it is on the same side of the guide rail 8 as the third leveling ramp 302.

[0090] The forced discharge slope 401 has a slope 4011 inclined to the upper right and a slope top plane 4012. The height of the slope top plane 4012 of the forced discharge slope 401 is higher than the bottom height of the leveling member 7 in a horizontal state, specifically, higher than the height of the bottom of the guide wheel 72. Therefore, when the jacking device 20 is absent or not working, the flap 3 can be tilted by the support of the forced discharge slope 401 on the guide wheel 72, and the unloading of the packages can still be achieved.

[0091] Furthermore, when the flap 3 passes through the lifting device 20, there is still a situation where the material cannot be unloaded due to the insufficient inclination angle of the flap 3. Correspondingly, the height of the top plane of the forced discharge slope 401 satisfies the requirement that the inclination angle of the flap 3 is greater than the inclination angle of the lifting device 20. This allows the flap to have a larger inclination angle, so that the package has a greater unloading power, ensuring that the package can slide down the flap smoothly.

[0092] On the other hand, the forced discharge device also includes a pair of first leveling slopes 402 symmetrically distributed on both sides of the track 8, the first leveling slopes 402 are located behind the forced discharge slope 20, and the position of each of the first leveling slopes 402 matches the position of the guide wheels 72 on both sides of the two-way flip trolley, and the height of the top plane 4021 of the first leveling slope 402 is equal to the bottom height of the leveling member in a horizontal state, specifically the same as the bottom height of the guide wheel 72, that is, when the two-way flip trolley 10 moves past the first leveling slope, the bottom of the guide wheels 72 on both sides thereof can respectively contact the top plane 4021 of the first leveling slope on one side.

[0093] When the bidirectional flap trolley passes through the lifting device 2 and becomes tilted, the two guide wheels 72 thereon are in a state of one high and one low. When the trolley passes through the first leveling slope 301, the guide wheel 72 at the low position contacts the first leveling slope 301 on its corresponding side and is gradually lifted up under the supporting force of the first leveling slope 301, thereby driving the flap to gradually flip to a horizontal state. When the two guide wheels 72 are both located at the flat plate position at the top of the first leveling slope 301, the two guide wheels 72 are at the same height, and the flap 3 becomes horizontal. At this time, when the leveled flap 3 passes through the subsequent forced discharge slope 401 again, the flap 3 has a larger tilt change, so that the components on it have a greater sliding power.

[0094] Furthermore, the present invention also discloses a flip plate sorting system, as shown in the attached Figure 6As shown, it includes the flip-plate sorting line, and also includes a loading area 70, a detection device 50 and a grid area 60. The loading area 70 is located near one end of the flip-plate sorting line, and the packages to be sorted can be placed on each two-way flip-plate trolley by manual or automated equipment; the detection device 50 can be any known software and hardware that can obtain and bind the data of the two-way flip-plate trolley number, the corresponding route of the package, and the flip-plate lifting device of the sorting port corresponding to the package route. Of course, it can also include a device for weighing the package and measuring the size. The grid area 60 includes a plurality of sorting ports, one sorting port is a route, and a lifting device 20 is arranged behind each of the sorting ports. When the two-way flip-plate trolley passes through the lifting device 20 corresponding to the sorting port, the package on it enters the corresponding sorting port, and each sorting port can be connected to other sorting equipment, such as various belt conveyor lines, roller conveyor lines, sorting AGV, etc., so as to be combined with other sorting methods, so as to effectively realize loading, route determination, sorting, and automatic or semi-automatic operations in sorting, thereby greatly improving efficiency.

[0095] There are many implementation methods of the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
