Description

Technical Field

[0001] The invention relates to the field of sorting conveyor belt manufacturing, and in particular to a magnetic high-speed sorting device. Background Art

[0002] There are three traditional ways of sorting goods: swing arm, round belt roller and disc. Each of these three sorting methods has its own disadvantages:

[0003] The swing-arm sorting method requires a large driving force and may damage the belt during use; the round belt roller sorting method is more complicated to install and the round belt will stretch, affecting production; the disc sorting method cannot achieve high-speed sorting due to its bulkiness.

[0004] The commonly used cross-belt sorting machine circulation system is composed of a small belt conveyor (referred to as the trolley) group and a circular track. The movement of the cross-belt sorting machine is completed by the trolley. When the trolley moves to the specified sorting position, the trolley rotates horizontally to complete the task of sorting out the goods. This sorting method improves the shortcomings of the traditional sorting method, does not increase the friction between the goods and the conveyor belt, and does not cause impact on the goods. However, the entire circulation system of the cross-belt sorting machine needs to be equipped with at least 350 sorting trolleys, and each trolley needs to be independently controlled, so the cost is very high. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an object of the present invention is to provide a magnetic high-speed sorting device.

[0006] A magnetic high-speed sorting device, comprising:

[0007] A toothed conveyor belt with a plurality of racks at the bottom, a T-shaped baffle plate is installed on the rack belt surface corresponding to the plurality of racks, an empty slot is left between the T-shaped baffle plates, a slider trolley is installed in the empty slot, a spring controlled by an armature is arranged in the slider trolley, and a push rod is arranged on the top of the slider trolley, through which the goods are pushed forward and guided;

[0008] A plurality of working magnetic mechanisms are obliquely installed below the toothed conveyor belt. The electromagnets of the working magnetic mechanisms reciprocate at an oblique angle to the running direction of the toothed conveyor belt under the push of the cylinder.

[0009] In a preferred embodiment of the present invention, the electromagnet of the working magnetic mechanism reciprocates along a slide groove which is inclined at an angle to the running direction of the toothed conveyor belt under the push of the cylinder, and a limit switch is provided at the end of the slide groove.

[0010] In a preferred embodiment of the present invention, the inclination angle is angle α, the belt linear speed is V1, the trolley lateral linear speed is V2, and tgα=V2 / V1.

[0011] In a preferred embodiment of the present invention, a return magnetic mechanism is provided at the terminal end of the toothed conveyor belt, and the slider trolley is attracted by the return magnetic mechanism to be sent back to the starting position.

[0012] In a preferred embodiment of the present invention, the return magnetic mechanism includes a return electromagnet controlled by a return cylinder, the return electromagnet slides on a return chute, and a return limit switch is provided at the end of the return chute.

[0013] The beneficial effects of the present invention are:

[0014] The present invention can push the goods into the collector at a high speed and smoothly. Compared with other sorting methods, it can greatly increase the speed of goods sorting and improve production efficiency, while also greatly reducing the manufacturing and use costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic structural diagram of the toothed conveyor belt of the present invention.

[0016] Figure 2 The structure diagram of the working magnetic mechanism of the present invention is shown in FIG. Figure 1 .

[0017] Figure 3 The structure diagram of the working magnetic mechanism of the present invention is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0018] like Figure 1 The magnetic high-speed sorting device 100 shown includes a toothed conveyor belt 110 with a plurality of racks 111 at the bottom, and a T-shaped baffle 113 is installed on the rack belt surface 112 corresponding to the plurality of racks 111.

[0019] An empty slot 114 is left between every two T-shaped baffles 113, and a slider trolley 120 is installed in the empty slot 114. The slider trolley 120 can make a reciprocating motion in the empty slot, and the push rod 123 on the top of the slider trolley 120 can push the goods forward along the empty slot 114, and also play a guiding role.

[0020] A spring 122 controlled by an armature 121 is arranged inside the slider trolley 120 , and a push rod 123 is arranged on the top of the slider trolley 120 , and the push rod 123 is used to push the cargo 500 forward and guide it.

[0021] A plurality of working magnetic mechanisms 200 are obliquely installed below the toothed conveyor belt 110 . The electromagnet 210 of the working magnetic mechanism 200 reciprocates along a slide 230 which is inclined at an angle to the running direction of the toothed conveyor belt 110 under the push of the cylinder 220 . A limit switch 231 is provided at the end of the slide 230 .

[0022] The inclination angle is angle α, the belt linear speed is V1, the trolley transverse linear speed is V2, and tgα=V2 / V1. Assuming the belt linear speed is V1, the trolley transverse linear speed is V2, and tgα=V2 / V1, the actual motion trajectory of the slider trolley 120 is an oblique line with an angle α to the running direction of the toothed conveyor belt 110, which is the same as the running trajectory of the electromagnet 210 slide rail.

[0023] Because of the above structure, the working principle of the present invention is:

[0024] When the goods enter the area 410 of the sorting target, the corresponding working magnetic mechanism 200 is energized, and the magnetic force of the electromagnet 210 attracts the armature 121 in the three connected slider trolleys 120 to press down the spring 122, and under the push of the cylinder 220, it moves from the starting position along the oblique slide 230 toward the direction 400 of the goods collector of the sorting target 1.

[0025] The slider trolley 120 moves laterally on the running toothed conveyor belt 110 until the goods are pushed into the goods collector.

[0026] A limit switch 231 is provided at the end of the slide slot 230 . When the electromagnet 210 contacts the limit switch 231 , the electromagnet 210 is powered off and the magnetic force disappears.

[0027] At this time, the electromagnet 210 is pulled back to the starting position by the cylinder 220, leaving the slider trolley 120 there; a return electromagnet 300 is set at the terminal 115 of the toothed conveyor belt 110, and when the slider trolley 120 remaining on this side moves to the return electromagnet 300, the return electromagnet 300 is energized to absorb the slider trolley 120 remaining on this side and move to the starting position of the slider trolley 120 under the push of the return cylinder 310; when the return electromagnet 300 touches the return limit switch 320, the return electromagnet 300 is de-energized, the slider trolley 120 is fixed at the starting position by the spring 122, and the return electromagnet 300 is pulled back to the starting position by the return cylinder 310, thus ensuring that the slider trolley 120 remaining on this side remains at the starting position of the slider trolley 120 when re-entering the working surface of the toothed conveyor belt 110.

[0028] Since the toothed conveyor belt 110 has a rack 111 at the bottom, the operation of the toothed conveyor belt 110 is achieved through the meshing between the rack 111 and a sprocket with teeth (not shown in the figure). No large tension is required between the toothed conveyor belt 110 and the driving sprocket (not shown in the figure), and the operation is reliable and the positioning is precise.

[0029] The slider trolley 120 magnetically attracted by the electromagnet 210 can also push the goods 500 into the collector 400 at high speed and smoothly, thereby ensuring high-speed, accurate and stable sorting of goods. Compared with other sorting methods, it can greatly improve the speed of sorting goods and improve production efficiency, and at the same time greatly reduce the manufacturing and use costs.
