[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1 like Figure 1 to Figure 2 , Figures 4 to 5 As shown, the present invention provides a flexible express sorting device, including an express conveying track 1; a rotation correction component 2 and a position correction component 3 are sequentially arranged on the express conveying track 1; a sorting mechanical arm component 4 is arranged on the express conveying track 1 away from the rotation correction component 2; a sorting port 5 is arranged on the express conveying track 1, and the position of the sorting port 5 corresponds to the position of the sorting mechanical arm component 4; the rotation correction component 2 includes a U-shaped flip frame 21 rotatably arranged on the express conveying track 1, and the U-shaped opening of the U-shaped flip frame 21 is provided on the inner walls. A correction roller assembly 22 is movably provided, a pushing cylinder 23 is provided on the bottom surface of the U-shaped opening of the U-shaped turning frame 21, and a pushing plate 231 is provided on the piston rod of the pushing cylinder 23; the sorting robot arm assembly 4 includes a sorting cylinder 41 arranged outside the express conveying track 1, a U-shaped sorting seat 42 is provided on the piston rod of the sorting cylinder 41, a touch rod 43 is rotatably provided in the U-shaped opening of the U-shaped sorting seat 42, the U-shaped opening of the U-shaped sorting seat 42 movably passes through the express conveying track 1, and the touch rod 43 is electrically connected to the sorting cylinder 41.

[0025] The express delivery conveyor track 1 is a belt conveyor belt or a plate conveyor belt. The express delivered in box packaging (hereinafter referred to as express delivered) is placed on the express delivery conveyor track 1 (close to the end of the rotation correction component 2) in sequence. The express delivered moves away from the position correction component 3 under the drive of the express delivery conveyor track 1. When the express delivered passes through the position correction component 3, the position of each express delivered can be kept uniform, and it is convenient for express delivered in different shapes and sizes to be unloaded through the sorting port 5 or the unloading port 11.

[0026] The rotation correction component 2 can correct the position of the express delivery, so that after passing through the position correction component 3, the express delivery can be unloaded through the sorting port 5 or the discharge port 11 under the action of the sorting robot arm component 4: that is, when the express delivery touches the touch rod 43 under the action of the express delivery conveyor track 1, the sorting cylinder 41 can be started to push the U-shaped sorting seat 42 and the touch rod 43 to push the express delivery toward the sorting port 5, thereby completing the unloading of the express delivery through the sorting port 5; when the express delivery does not touch the touch rod 43 under the action of the express delivery conveyor track 1, the sorting cylinder 41 will not be triggered to start, and the express delivery can be unloaded through the discharge port 11 under the action of the express delivery conveyor track 1.

[0027] Embodiment 2 Based on the first embodiment, Figures 1 to 3 , Figure 5As shown, a conveying plate 6 is also provided on the outside of the express conveying track 1. The conveying plate 6 and the express conveying track 1 are on the same flat plate. A rotating motor 61 is embedded in the conveying plate 6. An adjusting disk 62 is coaxially provided on the output shaft of the rotating motor 61. The adjusting disk 62 is embedded in the conveying plate 6, and the top surface of the adjusting disk 62 is on the same plane as the top surface of the conveying plate 6; a U-shaped flip frame 21 is provided on the side wall of the conveying plate 6 away from the express conveying track 1, and both ends of the U-shaped opening of the U-shaped flip frame 21 are rotatably hinged with a correction seat 63, and the correction roller assembly 22 is provided on the correction seat 63. The correction roller assembly 22 includes an intermediate plate 221, and the intermediate plate 221 is provided on the side wall of the correction seat 63, and the intermediate plate 2 21 wherein the two opposite side walls are both open; two rotating arc plates 223 are provided, and one arc end of the two rotating arc plates 223 is rotatably hinged to one end of the two telescopic plates 222 away from the middle plate 221 through a rotating shaft 1 2231 with a torsion spring; a correction roller mounting seat 224 is hinged between the other arc ends of the two rotating arc plates 223 through a rotating shaft 2241 with a torsion spring; a plurality of correction rollers 225 are provided, and the plurality of correction rollers 225 are rotatably arranged in sequence on the side wall of the correction roller mounting seat 224 away from the middle plate 221; both ends of the U-shaped opening of the U-shaped flip frame 21 are provided with flip motors 631, and the correction seat 63 is arranged on the output shaft of the flip motor 631.

[0028] First, the flip motor 631 is started to drive the correction seat 63 to rotate in the direction away from the adjustment disk 62, and the express package (hereinafter referred to as the express package) packed in the box is placed on the adjustment disk 62; the flip motor 631 is started to drive the correction seat 63 to rotate in the direction close to the adjustment disk 62; the correction roller 225 is in conflict with the box of the express package, so that the position of the express package placed crookedly on the adjustment disk 62 can be corrected (the rotating arc plate 223 is made of elastic material. When the correction roller 225 conflicts with the express package, the rotating arc plate 223 can play a certain buffering role, which is beneficial to prevent the box of the express package from being squeezed and deformed); the rotating motor 61 can also be started to drive the adjustment disk 62 to rotate, so that the express package placed on the adjustment disk 62 can be rotated and adjusted, that is, the position of the express package can be corrected; when the position of the express package placed on the adjustment disk 62 is adjusted, the pushing cylinder 23 is started to drive the pushing plate 231 to push in the direction close to the adjustment disk 62, so that the express package placed on the adjustment disk 62 can be pushed to the express delivery track 1, so that the express package continues to be transported under the action of the express delivery track 1.

[0029] The flip motor 631 can also be started to drive the correction seat 63 to rotate in the direction away from the adjustment disk 62, so that the two middle plates 221 are parallel to each other (at this time, the vertical planes where the axes of the correction rollers 225 on the two correction seats 63 are located are also parallel to each other). The express can be inspected and placed between the correction rollers 225 on the two correction seats 63, and then under the action of the pushing cylinder 23, the express can be pushed one by one onto the express conveying track 1 for transportation.

[0030] Two telescopic plates 222 are provided, and the two telescopic plates 222 are movably arranged in the openings of the side walls at both ends of the middle plate 221, and the two telescopic plates 222 on the same middle plate 221 are connected by multiple return springs 2211; this can prevent the correction roller 225 from conflicting with the express box when the clamping force is too large. At this time, the telescopic plate 222 can squeeze the return spring 2211 on the middle plate 221, thereby having a certain buffering effect on the clamping force and preventing the express box from being damaged.

[0031] Embodiment 3 Based on the first embodiment, Figure 1 As shown, the position correction component 3 includes a correction cylinder 31 embedded in the opposite side walls of the express conveying track 1, and a roller seat 32 is arranged on the piston rod of the correction cylinder 31. A plurality of rotating rollers 33 are arranged in parallel and at intervals on the side walls of the roller seat 32, and the axis of the rotating roller 33 is perpendicular to the bottom surface of the express conveying track 1; the correction cylinder 31 away from the end of the sorting robot arm assembly 4 can be started to drive the roller seat 32 to shrink, so that the end of the roller seat 32 away from the correction cylinder 31 is flush with the opening of the sorting port 5, and at the same time, according to the size of the express, another correction cylinder 31 can be started to push the roller seat 32 and the rotating roller 33 to the corresponding position, so that the express can pass between the two position correction components 3 when being transported on the express conveying track 1, which is beneficial to the stability of the position of the express after being pushed out from the discharge port 11.

[0032] When it is necessary to sort express parcels of various sizes at the same time, the ends of the roller seats 32 in the two position correction assemblies 3 away from the correction cylinder 31 can be made flush with the opening of the sorting port 5 at the same time; when the express parcel is placed on the express conveying track 1, one of the sides of the express parcel is made to contact with the correction cylinder 31 away from the end of the sorting robot arm assembly 4, and as the express parcel on the express conveying track 1 is conveyed, it contacts with the position correction assembly 3 away from the end of the sorting robot arm assembly 4 (that is, it contacts with the rotating roller 33); as the express parcel is conveyed on the express conveying track 1, when the size of the express parcel is small (the express parcel will not contact with the sorting robot arm assembly 4 at this time), it can be directly unloaded from the unloading port 11 through the sorting robot arm assembly 4; when the size of the express parcel is large, the express parcel contacts with the sorting robot arm assembly 4 at this time, triggering the sorting robot arm assembly 4 to push the express parcel to the sorting port 5 to complete the unloading.

[0033] Embodiment 4 Based on the first embodiment, Figure 1 , Figures 4 to 5 As shown, a feeding port 11 is provided at one end of the express delivery conveying track 1 away from the conveying plate 6; a touch rod 43 is obliquely arranged in the U-shaped opening of the U-shaped sorting seat 42, and a distance from one end of the touch rod 43 close to the feeding port 11 to the sorting port 5 is greater than a distance from one end of the touch rod 43 away from the feeding port 11 to the sorting port 5, an end of the touch rod 43 close to the feeding port 11 is located outside the U-shaped opening of the U-shaped sorting seat 42, and an end of the touch rod 43 away from the feeding port 11 is located inside the U-shaped opening of the U-shaped sorting seat 42; on the express delivery conveying track 1 A seat groove 12 is provided which is matched with the size of the U-shaped sorting seat 42, the U-shaped opening of the U-shaped sorting seat 42 faces the direction of the sorting port 5, the U-shaped sorting seat 42 is movably arranged in the seat groove 12, and the end face of the U-shaped opening of the U-shaped sorting seat 42 is in the same vertical plane as the seat groove 12; a rod frame 421 is provided in the U-shaped opening of the U-shaped sorting seat 42, the touch rod 43 is connected to the rod frame 421 by a bolt 422, and a pressure sensor is provided on the side wall of the touch rod 43 close to the sorting port 5, and the pressure sensor is electrically connected to the sorting cylinder 41.

[0034] When the outer dimensions of the express packaged in the box are relatively large, the express package touches the end of the touch rod 43 close to the discharge port 11 (the end of the touch rod 43 close to the discharge port 11 corresponds to the position of the express conveying track 1 up and down), so that the touch rod 43 can rotate in the U-shaped opening of the U-shaped sorting seat 42. After the pressure sensor receives the pressure signal, the sorting cylinder 41 can be started to push the U-shaped sorting seat 42 and the touch rod 43 to move toward the sorting port 5 at the same time (the pressure sensor realizes the control of the cylinder as an existing technology, so it will not be repeated here), so that the express package can be pushed into the sorting port 5 to complete the unloading; after the unloading is completed, the sorting cylinder 41 drives the U-shaped sorting seat 42 and the touch rod 43 to return to the seat groove 12.

[0035] When the dimensions of the express packaged in the box are small, the express package will not touch the touch rod 43 , so the express package can be directly unloaded from the unloading port 11 under the transportation of the express delivery track 1 .

[0036] An adjusting motor may be embedded in the rod frame 421, and a bolt 422 passes through the rod frame 421 and is connected to the output shaft of the adjusting motor, so that when the express touches the rod frame 421, the rod frame 421 can be rotated to be perpendicular to the side wall of the U-shaped opening of the U-shaped sorting seat 42, which is beneficial for the rod frame 421 to maintain the horizontality when pushing the express to move to the sorting port 5. When the express is pushed, the rod frame 421 is rotated under the action of the adjusting motor to keep the touch rod 43 tilted in the U-shaped opening of the U-shaped sorting seat 42 (that is, the distance from the end of the touch rod 43 close to the discharge port 11 to the sorting port 5 is greater than the distance from the end of the touch rod 43 away from the discharge port 11 to the sorting port 5).

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
