[0028] See also Figures 1 to 7 The utility model provides a front-to-back arrangement of a multi-station sorting device, comprising: a conveying device 1 and a plurality of sorting devices arranged and distributed in a front-to-back interval, wherein the conveying device 1 is arranged through the plurality of sorting devices. It should be noted that the front and back are based on the conveying direction of the conveying device 1, and the upstream along the conveying direction of the conveying device 1 is the front and the downstream is the rear. The conveying device 1 is used to convey a material tray 2 carrying materials to be sorted to each sorting device for sorting.

[0029] The materials on the loading tray 2 can be cut by a cutting device located upstream of the front-to-back multi-station sorting device of the present invention.

[0030] Furthermore, each sorting device includes a lifting device 3 and a sorting robot 4, the lifting device 3 is used to lift the loading tray 2 transported to the position by the conveying device 1, and the sorting robot 4 is used to sort the materials on the loaded tray 2 lifted to the position.

[0031] like Figure 2As shown, when the upstream sorting device is in the sorting state, that is: the conveying device 1 transfers the loading tray 2 to the upstream sorting device and is lifted up into place by the lifting device 3, the upstream sorting robot 4 is in the sorting state, the conveying device 1 can convey the next loading tray 2 through the upstream sorting device and flow to the downstream sorting device. At this time, the lifting device 3 of the downstream sorting device lifts the loading tray 2 upward into place for the downstream sorting robot 4 to sort; in this way, multiple sorting devices can work simultaneously without waiting for each other, which can greatly improve the sorting efficiency.

[0032] It is worth mentioning that the sorting robot 4 of each sorting device in the present invention can sort and classify all the materials on the material tray 2, for example Figure 1 The two sorting robots 4 shown in the figure will sort until all the materials on their respective loading trays 2 are sorted; they can also sort only large or small items according to the settings, for example, by setting up four sorting devices, the first and third sorting devices sort small items, and the second and fourth sorting devices sort large items. In this way, they can be used according to needs, which greatly increases practicality.

[0033] See also Figure 5 The conveying device 1 includes two parallel conveying rollers of the same height and a first driving device which is transmission-connected to the conveying rollers. The width of the loading tray 2 is greater than the spacing between the two conveying rollers so that both sides of the loading tray 2 can overlap on the two conveying rollers. The first driving device is used to drive the two conveying rollers to rotate so as to convey the loading tray 2 to flow to each sorting device.

[0034] The two conveying rollers are each composed of a plurality of rollers 11 arranged at intervals, and the conveying device 1 further comprises a roller mounting frame 12.

[0035] Optionally, the lifting device 3 adopts any one or a combination of a worm gear screw lift, a hydraulic lift, a rack and pinion lift and a screw lift.

[0036] In this embodiment, the lifting device 3 is specifically a worm gear screw lift, and each sorting device includes two lifting devices 3 , which are respectively arranged on two outer sides of the conveying device 1 .

[0037] Among them, the lifting devices 3 include multiple worm gear screw devices and a second driving device that is transmission-connected to the multiple worm gear screw devices. The worm gear screw devices include a lifting block 31, and the lifting block 31 is located directly below the loading tray 2 that flows to the sorting device. The second driving device is used to drive the multiple worm gear screw devices to move synchronously and drive the lifting block 31 to move upward to lift the loading tray 2.

[0038] It is worth mentioning that the conveying device 1 also includes a plurality of transition wheels 15, which are rotatably mounted on the roller mounting frame 12. The chain of the chain transmission mechanism 14 is wound around the roller 11 and the transition wheel 15. The transition wheel 15 is used to change the winding path of the chain so that it avoids the lifting block 31 to avoid interfering with the lifting movement of the lifting block 31.

[0039] See also Figure 6 and Figure 7 Each worm gear screw device also includes a lifting bracket 32 ​​arranged vertically, a worm gear module 33 fixed to the bottom of the lifting bracket 32, a screw 34 arranged on the lifting bracket 32 ​​and connected to the worm gear module 33, and a lifting nut 35 sleeved on the screw 34. The lifting block 31 is fixedly connected to the lifting nut 35. The multiple worm gear modules 33 located on the same side of the conveying device 1 are connected to each other through a transmission shaft 36. The second driving device includes a second reduction motor 37, which is transmission-connected to one of the worm gear modules 33. The second reduction motor 37 is used to drive the multiple worm gear modules 33 to rotate synchronously, and drive the lifting block 31 to perform synchronous lifting and lowering movements through the screw 34 and the lifting nut 35. The worm gear screw devices located on the same side are linked by the transmission shaft 36, and are driven to move synchronously by the second reduction motor 37, so as to achieve stable driving of the loading tray 2 to perform lifting and lowering movements.

[0040] In addition, the worm gear screw device also includes a connecting frame 38, which is fixed on the lifting nut 35, and the lifting block 31 is fixedly installed on the connecting frame 38. Guide wheels 39 are axially arranged on both sides of the connecting frame 38, and optionally, the guide wheels 39 are U-shaped pulleys; both inner sides of the lifting bracket 32 ​​are vertically provided with slide rails 310, and the guide wheels 39 are slidably matched on the corresponding slide rails 310, and the guide wheels 39 and the slide rails 310 are used in conjunction with each other to play a guiding role and improve the stability of lifting.

[0041] Optionally, the sorting robot 4 adopts any one or a combination of a gantry robot, an articulated robot, a coordinate robot and a truss robot. The sorting robot 4 can use an electromagnet to pick up the materials on the loading tray 2 and stack the materials into a specified material frame as required.

[0042] It can be seen that the front-to-back multi-station sorting device of the present invention is provided with a conveying device 1 and a plurality of arranged and distributed sorting devices. The conveying device 1 is arranged between the plurality of sorting devices. When the conveying device 1 transfers the loading tray 2 to the upstream sorting device and is lifted up by the lifting device 3 of the upstream sorting device to be sorted by the sorting robot 4, the conveying device 1 can convey the next loading tray 2 through the upstream sorting device and transfer it to the downstream sorting device for sorting by the downstream sorting robot 4, thereby realizing that a plurality of sorting devices work at the same time without waiting for each other, which can greatly improve the sorting efficiency, and this structural layout is reasonable and ingenious, which can save space and reduce equipment costs.
