[0030] The purpose, advantages and characteristics of the utility model will be illustrated and explained through the non-restrictive description of the preferred embodiments.

[0032] Example 1

[0033] The three-dimensional sorting device disclosed by the present invention is described below in conjunction with the accompanying drawings. Figure 1 , Attachment Figure 2 As shown, it includes a circle of sorting carts 100 that move along the track 200 and form a sorting loop. The sorting conveyor 110 on the sorting cart 100 can move up and down to adjust the sorting height. The specific structure of the three-dimensional sorting device can refer to the patent literature described in the background technology, and of course it can also be the structure disclosed in the patent literature with authorization announcement number CN111014052B.

[0034] The three-dimensional sorting device further includes a height detection mechanism 300 for detecting the height of the sorting conveyor 110 on each of the sorting carts 100. The height detection mechanism 300 can use different detection sensors as needed;

[0035] When the detection sensor used by the height detection mechanism 300 is a diffuse reflection sensor, the height detection mechanism 300 includes a group of diffuse reflection sensors arranged outside one end of the sorting trolley 100 and distributed at equal intervals along the vertical direction; when the diffuse reflection sensor is used, by adjusting the detection distance of the diffuse reflection sensor, the diffuse reflection sensor can detect the end of the sorting conveyor 110 of each sorting trolley 100, so that the height of the sorting conveyor 110 can be determined by detecting the position of the diffuse reflection sensor at the end of the sorting conveyor 110.

[0036] When the detection sensor used by the height detection mechanism 300 is a through-beam sensor, the height detection mechanism 300 includes a transmitter arranged on the sorting conveyor 110 of each sorting cart 100 and a group of receivers arranged outside one end of the sorting conveyor 110 and distributed at equal intervals in the vertical direction; at this time, the height of the sorting conveyor 110 is determined according to the position of the receiver that receives the light emitted by the transmitter.

[0037] As attached Figure 1 , Attachment Figure 3As shown, when the detection sensor used by the height detection mechanism 300 is a mirror reflection sensor, the height detection mechanism 300 includes a reflective plate 310 provided on the sorting conveyor 110 of each of the sorting carts 100 and a group of reflective sensor components 320 provided outside one end of the sorting conveyor 110 and distributed at equal intervals in the vertical direction. The height of the sorting conveyor 110 is determined based on the position of the reflective sensor component 320 detected by the reflective plate 310.

[0038] More preferably, the height detection mechanism 300 uses a mirror reflection sensor. Accordingly, the reflective plate 310 is set at the end surface of the frame of the sorting conveyor 110, and the spacing between adjacent reflective sensor components 320 is smaller than the length of the reflective plate 310 (that is, the distance between the upper side and the lower side of the reflective plate 310). In this case, the height of the sorting conveyor 110 can be determined based on the positions of the two reflective sensor components 320 detected by the reflective plate 310.

[0039] As attached Figure 3 , Attachment Figure 4 As shown, for ease of installation, the diffuse reflection sensor, reflector, and reflective sensor assembly 320 are mounted on a sensor bracket 330, which is mounted on a mounting bracket 400 on the side of the track 200. The sensor bracket 330 includes a "J"-shaped body, with connecting plates 331 at the upper and lower ends of the body respectively screwed to the mounting bracket 400. In order to facilitate the adjustment of the spacing between the diffuse reflection sensors, reflectors or reflective sensor assemblies 320, a group of waist-shaped holes 333 extending in the vertical direction are provided on the vertical plate 332 of the main body, and a group of waist-shaped holes 333 are arranged at equal intervals along the vertical direction. Each of the diffuse reflection sensors, reflectors and reflective sensor assemblies 320 is arranged at an adjustable installation height at one of the waist-shaped holes 333, that is, each diffuse reflection sensor, reflector and reflective sensor assembly 320 is provided with at least one connecting hole for screwing with the main body, preferably two and distributed along the vertical direction, and the position adjustment of the diffuse reflection sensor, reflector and reflective sensor assembly 320 is achieved by adjusting the positions of the two connecting holes and the waist-shaped holes 333.

[0040] As attached Figure 3 As shown, an auxiliary connecting plate 334 is provided in the middle position of one side of the main body on which the diffuse reflection sensor, reflector and reflective sensor assembly 320 are installed. The auxiliary connecting plate 334 is L-shaped and is integrally formed with the main body. Of course, it can also be welded and fixed. The auxiliary connecting plate 334 is screwed to the mounting bracket 400, thereby improving the structural strength of the main body and preventing deformation of the main body from affecting the detection accuracy of the detection sensor.

[0041] As shown in the accompanying drawings, Figure 3 The diffuse reflection sensor, the reflector and the reflective sensor assembly 320 are located between the vertical plate 332 of the body and the mounting frame 400, so that they can be protected to some extent and the risk of collision with external structures is reduced.

[0042] As shown in the accompanying drawings, Figure 1 In order to ensure high reliability and timeliness, the height detection mechanism 300 is arranged at least one end of each straight section of the sorting loop, and preferably, when the sorting loop is waist-shaped, the height detection mechanism 300 is arranged at both ends of the two straight sections.

[0045] The utility model still has a variety of implementation manners, all technical schemes formed by using equivalent transformation or equivalent transformation, all fall within the protection scope of the utility model.
