Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 to 3, the structure of the turnover sorting system includes a support 1 and a conveying assembly 2, both ends of which are rotatably mounted on the support 1, and the support 1 is further provided with a turnover driving mechanism 3 for driving the conveying assembly 2 to turn over on the support 1, and the turnover direction is perpendicular to the conveying direction of the conveying assembly 2.

As shown in fig. 3 and 4, the number of the conveyor assemblies 2 in the sorting system is generally not less than two, each set of the conveyor assemblies 2 is arranged on the support 1 in sequence along the conveying direction of the conveying belt 2d, and the material frames 9 are placed on both sides of each conveyor assembly 2.

Above-mentioned conveyor components 2's structure includes framework 2a, framework 2 a's both ends are equipped with left back shaft 2e and right back shaft 2f respectively, left back shaft 2e and right back shaft 2f all rotate through the bearing and install on support 1, be equipped with initiative cylinder 2b and driven cylinder 2c in framework 2a, the cover is equipped with conveyor belt 2d on initiative cylinder 2b and the driven cylinder 2c, and initiative cylinder 2b directly adopts electric cylinder, but direct drive conveyor belt 2d operates, need not external motor.

The overturning driving mechanism 3 comprises a motor 3a fixedly arranged on the bracket 1, a lower belt pulley 3d is arranged on an output shaft of the motor 3a, an upper belt pulley 3c is arranged on the left supporting shaft 2e, and a driving belt 3b is sleeved on the upper belt pulley 3c and the lower belt pulley 3 d.

Based on the structural layout of the turnover sorting system, an article 8 is placed on a conveying belt 2d, the electric roller (i.e. a driving roller 2b) rotates to realize horizontal conveying of the article 8, when the article 8 needs to be sorted into a material frame 9, a motor 3a works to drive a driving belt 3b to rotate, the driving belt 3b can pull the conveying component 2 to turn 180 degrees around a support 1, the article 8 falls into the material frame 9 due to the turning force and gravity, at the moment, the upper surface of the conveying belt 2d turns over for 180 degrees to become the lower surface of the conveying belt 2d, the lower surface also becomes the upper surface, the conveying direction of the conveying belt 2d is reversed, and therefore, in the process of turning 180 degrees of the conveying component 2, the working process of the electric roller (i.e. the driving roller 2b) is decelerated → stopped → reversely rotated to ensure that the conveying component 2 turns over for 180 degrees, the conveying direction of the conveying belt 2d is kept constant, thereby realizing continuous conveyance and article discharge.

In order to avoid the electric roller from turning over along with the conveying component 2, the electric conduction and control cable is not wound, and the electric slip ring 4 is sleeved on the left supporting shaft 2 e.

As shown in fig. 1 and 3, in the conventional design of the conveying belt 2d, the upper and lower surfaces of the conveying belt 2d are parallel to each other, that is, the conveying surfaces are arranged horizontally, and since a transition gap exists between two adjacent conveying assemblies 2 in the sorting system, when the articles 8 are conveyed from the rear end to the front end, the articles 8 stay on the transition region between the two conveying assemblies 2 due to gravity, friction and other factors, so that the articles 8 are stopped or jammed in the gap, and the conveying rhythm is broken, which affects the sorting efficiency of the articles 8. In view of the technical defects, the distance between the upper side and the lower side of the conveying belt 2d in the embodiment gradually increases along the conveying direction, when the conveying assemblies 2 are arranged in the sorting system in an assembling manner, the upper side of the conveying belt 2d is inclined, and the left end of the conveying belt 2d is higher than the right end of the conveying belt, that is, the position of the conveying belt 2d on the driven roller 2c is higher than that of the next driving roller 2b, so that when the articles 8 are conveyed, the articles directly fly onto the next conveying assembly 2 from the current conveying assembly 2, the articles are prevented from being stopped or being clamped between the two conveying assemblies 2, and the sorting efficiency and the fluency of the system are favorably improved.

As shown in fig. 1 and 5, in order to make the left end of the conveyor belt 1 higher than the right end, the following two ways are available:

the first method is as follows: the diameter of the driven roller 2c is made larger than that of the driving roller 2 b.

The second method comprises the following steps: the two driven rollers 2c are distributed along the vertical direction, and the total height of one side of the two driven rollers 2c is larger than the diameter of the driving roller 2b, namely the sum of the diameters of the two driven rollers 2c and the distance between the two driven rollers is larger than the diameter of the driving roller 2 b.

Furthermore, in the second mode, the distances between the two driven rollers 2c and the driving roller 2b are equal, that is, the two driven rollers 2c and the driving roller 2b are arranged in an isosceles triangle, the upper side and the lower side of the conveying belt 2d are symmetrically distributed on the upper side and the lower side of the axial line of the left support shaft 2e, that is, the upper side and the lower side of the conveying belt 2d are symmetrical to each other relative to the axial line of the left support shaft 2e, so that the design can enable the conveying assembly 2 to keep the original inclined conveying state after being turned over by 180 degrees on the bracket 1, and the lower side of the conveying assembly faces upwards.

In the first mode, it should be noted that the driven roller 2c is located at the feeding end, and the height of the position is greater than that of the feeding start end, however, according to the actual application requirement, the driving roller 2b may be arranged at the feeding end, that is, the driving roller 2b and the driven roller 2c are switched, and in this case, it is required to ensure that the diameter of the driving roller 2b is greater than that of the driven roller 2 c.

As shown in fig. 3, in the sorting system, a sensor 5 is provided between two adjacent conveyors to detect whether an article 8 is smoothly fed into the next conveyor, and a cover plate 6 is installed at a transition area of two adjacent conveyors, and the cover plate 6 is disposed obliquely.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
