Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to an automatic sorting device for express items. Background Art

[0002] During the delivery process, express delivery needs to be transferred in the transit yard. The transit yard generally has sorting equipment, which is used to sort and organize express delivery, so that express delivery with the same delivery location can be sorted together to improve the transportation efficiency of express delivery. Express delivery sorting equipment generally includes a sorting conveyor device and multiple sorting crossings. The express delivery on the sorting conveyor device will be sorted to each sorting crossing, and then the express delivery in each sorting crossing will be delivered to the destination by express delivery vehicles and other transportation equipment.

[0003] As we all know, the most important link of the sorting machine is the conveying stage throughout. At present, most of the conveying methods are inseparable from the conveyor belt. In order to keep the conveying process smooth and meet the purpose of transportation in different directions, more than one conveyor belt is often set on the transportation line. At this time, gaps and "grooves" will inevitably appear at the joints of the conveyor belts. This is also the "accident" section that is most prone to jamming and blockage during the transportation process. How to solve the jamming of the docking section on the conveyor belt is an urgent problem to be solved nowadays; therefore, we propose a new self-delivery sorting device that can solve the jamming problem at the junction of express sorting conveyor belts. Summary of the invention

[0004] In order to solve the problem that the grooves at the joints of the conveyor belt in the prior art easily cause express parcels to be blocked and thin parcels to be clamped:

[0005] The present invention proposes an automatic sorting device for express parcel specifications, comprising a conveyor frame neatly arranged on a conveyor line, the conveyor frame comprising two parallel side roller frames in an arched structure, and a same connecting support plate is fixed between the top ends of the two side roller frames, and conveyor rollers parallel to each other are fixed near the top at both ends of the conveyor frame, and a same conveyor belt is wound between the two conveyor rollers, the upper surface of the connecting support plate is lower than the height of the top end of the side roller frame, and the upper surface of the conveyor belt is lower than the height of the top end of the side roller frame, so as to ensure that the side roller frame can form a role similar to a guardrail, and an L-shaped cantilever frame is fixed to the top end of the side roller frame near the rear side of the conveyor frame, and the top end of the L-shaped cantilever frame A scanning and identification device is arranged near the upper middle part of the conveyor belt; two vertical and open grooved slide rails are fixed at the junction of the two conveyor frames, and anti-twist sliders are slidably connected in the slide grooves of the two grooved slide rails, the two anti-twist sliders always keep the same height, and the same transition slat is fixed between the tops of the two anti-twist sliders by bolts, and arc groove one and arc groove two with the same curvature are respectively opened on both sides of the transition slat, and the length of arc groove one is longer than that of arc groove two, that is, the top end of the transition slat is set as an inclined plane, and the height of the inclined plane close to the incoming material end is higher than that of the other end, and the highest end of the top of the transition slat is lower than the conveying plane of the conveyor belt.

[0006] A further arrangement of the present invention is that adjustment ear plates are fixed near the bottom ends of the groove bottoms of the two groove-type slide rails, and self-locking screw holes are opened on the upper surfaces of the two adjustment ear plates, and adjustment screws are threaded in the self-locking screw holes, and tension springs are fixed to the top ends of the adjustment screws, and the top ends of the tension springs are fixed to the lower surface of the anti-twist slider on the side; by means of the tension springs arranged under the anti-twist slider, the extension length of the adjustment screws can be adjusted according to the demand for the gap, thereby changing the overall height of the transition slats.

[0007] A further configuration of the present invention is that both ends of the arc groove one and the arc groove two are provided with transverse roller grooves near the top edges, and rotatable rollers are provided in the roller grooves, and the roller surfaces of the rollers protrude from the surfaces where the bottoms of the arc grooves one and the arc grooves two are located; by providing the rollers at the bottoms of the arc grooves one and the arc grooves two, when the excess slats are tightened downward, it is possible to avoid the excess slats from being in too close contact with the surface of the conveyor belt, thereby causing the conveyor belt to be locked and stuck.

[0008] A further configuration of the present invention is that a suspension rod is fixed on the lower surface of the top cross beam of the L-shaped cantilever frame near the rear side, and a lighting device inclined toward the middle of the conveyor belt is fixed at the bottom end of the suspension rod; through the set lighting device, the barcode information on the upper surface of the express item can be observed more clearly.

[0009] A further arrangement of the present invention is that the L-shaped cantilever frame is fixed to 1 / 3 of the upper surface of the conveyor frame near the junction, and a bearing hole is opened on the upper surface of the side roller frame near the rear side, and a tapered roller bearing is clamped in the bearing hole, and a transmission rod is rotatably connected in the tapered roller bearing, and a servo motor and a baffle are respectively fixed at the upper and lower ends of the transmission rod; the length of the baffle is equal to 2 / 3 of the length of the conveyor frame, and a notch is opened at the top of the side roller frame on the other side, and the bottom of the notch is flush with the upper surface of the connecting support plate; through the arranged servo motor and the notch matched with the direction of the baffle, when the scanning and identification device identifies the express item of the destination, the baffle can be controlled to rotate 45 degrees to the middle position of the conveyor belt, that is, the other end of the baffle reaches the other end of the notch, and the express item can be gently delivered to the destination with the help of the advancing conveyor belt.

[0010] A further configuration of the present invention is that a plurality of staggered ball grooves are provided on one side of the baffle plate close to the notch, and balls are embedded in the ball grooves, and the surface of the balls protrudes from the surface of the baffle plate; by providing the protruding balls on the surface of the baffle plate, the static friction between the side of the express item and the baffle plate can be reduced, thereby ensuring that the express item slides away smoothly.

[0011] A further configuration of the present invention is that a sloped chute inclined toward the outside of the conveyor frame is opened at the bottom of the notch, and a discharge guide plate is fixed on the outside of the conveyor frame near the lower mouth of the sloped chute, the slope of the discharge guide plate is the same as the inclination of the sloped chute, and pocket hooks are arranged on both sides of the bottom end of the discharge guide plate; the arranged sloped chute facilitates the express parcels to leave the conveyor belt quickly.

[0012] A further configuration of the present invention is that a support frame with an opening upward and a rectangular structure is fixed to the side of the conveyor frame near the bottom of the discharge guide plate, and magnet grooves are opened on the outer walls of the two opposite sides of the support frame near the four corners of the top, and a snakeskin bag is sleeved at the opening of the support frame. The opening of the snakeskin bag is rolled outward and sleeved on the opening of the support frame, and is adsorbed in the magnet groove by a magnet to fix the bag opening.

[0013] A further arrangement of the present invention is that a bellows is fixed in the middle of the bottom inner wall of the support frame, and a support plate is fixed to the top of the bellows, a hard air pipe extending out of the outside of the support frame is inserted into the bottom side of the bellows, an air distributor is fixed at the end of the hard air pipe away from the bellows, and a balloon is sleeved at the outlet of the air distributor; by providing a balloon sleeved on the air distributor, when no express items fall, the support plate will lift the bottom of the snakeskin bag to prevent the express items from falling to the bottom of the support frame and causing damage due to the large drop; as the weight accumulates, the support plate slowly descends to the bottom, so that the fallen express items always maintain a low drop when falling into the support frame, avoiding damage to the express items.

[0014] A further configuration of the present invention is that a return spring is provided in the bellows to adjust the load-bearing capacity of the support plate in accordance with the number and quality of the balloons.

[0015] The beneficial effects of the present invention are:

[0016] 1. By setting a transition slat between the two conveying units, the height of the two anti-twist sliders can be controlled to be lowered in advance when conveying thinner express parcels, so that the distance between the top edge of the transition slat and the conveyor belts on both sides can be smaller. At this time, the express parcel is not easy to fall into the gap between the two conveyor belts, ensuring smooth transmission. Under the action of inertia and gravity, the head of the express parcel will horizontally cross the edge of the transition slat, and then smoothly reach the upper surface of the transition slat to prevent it from being bitten into the gap.

[0017] 2. By setting the tension spring under the anti-twist slider, the extension length of the adjusting screw can be adjusted according to the demand for the gap, thereby changing the overall height of the transition slat; and the rollers set at the bottom of the arc groove 1 and the arc groove 2 can prevent the transition slat from being in too close contact with the surface of the conveyor belt when the transition slat is tightened downward, thereby causing the conveyor belt to lock and jam.

[0018] 3. By setting a balloon connected to the air distributor, when there is no express falling, the pallet will lift the bottom of the snakeskin bag to prevent the express from falling to the bottom of the pallet frame and causing damage due to the large drop; as the weight accumulates, the pallet slowly descends to the bottom, so that the falling express always maintains a low drop and falls into the pallet frame to avoid damaging the express.

[0036] Reference Figure 1 and Figure 7 A slope chute 11 inclined toward the outside of the conveyor frame 1 is opened at the bottom of the notch, and a discharge guide plate 12 is fixed to the outside of the conveyor frame 1 near the lower mouth of the slope chute 11.
