As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the present invention discloses a roll-over type sorting apparatus 10 based on drum transfer, comprising: a main line drum conveyor 20, a plurality of weight sorting devices 30, and a plurality of branch conveyors 40. The plurality of weight sorting devices 30 are respectively installed at different positions of the main line roller conveying device 20, the plurality of branch line conveying devices 40 are arranged at one side of the main line roller conveying device 20, the conveying direction of the branch line conveying devices 40 is perpendicular to the conveying direction of the main line roller conveying device 20, and the positions of the plurality of branch line conveying devices 40 correspond to the positions of the plurality of weight sorting devices 30 one by one.

The main line drum transport device 20 includes: an input end 21, an output end 22 and a transport plane 23. It should be noted that the input end 21, the output end 22, and the conveyance plane 23 do not refer to actual structures, but refer to relative positions. The articles are placed on a transport plane 23 at the input end 21 and subsequently moved on the transport plane 23 in the direction of the output end 22; during this movement, the articles are sorted by the weight sorting apparatus 30 to a different branch conveyor 40, while the unsorted articles exit the main line drum conveyor 20 from the output 22.

Specifically, as shown in fig. 4 and 5, the main line drum conveying device 20 includes: a fixed bracket 24, a roller 25, a transmission motor 26 and a plurality of turnover plates 27. The number of the rollers 25 is multiple, the rollers 25 are rotatably arranged on the fixed support 24 and located on the conveying plane 23, the transmission motor 26 drives the rollers 25 to rotate through a belt (not shown), the turnover plates 27 are located on the conveying plane 23, each turnover plate 27 is arranged between two adjacent rollers 25, one end of each turnover plate 27 is rotatably arranged on the fixed support 24, and the weight sorting devices 30 respectively drive the turnover plates 27.

In the present embodiment, as shown in fig. 2 and 6, the branch conveyor 40 has a drum-type structure. The branch conveyor 40 includes a support frame 41 and branch rollers (not shown) rotatably mounted on the support frame 41, the branch rollers forming a branch conveying surface 42 of the branch conveyor 40, the branch conveying surface 42 being inclined with respect to the conveying plane 23. That is, as shown in fig. 6, the side of the supporting frame 41 close to the main line roller conveyor 20 is higher, and the other side far from the main line roller conveyor 20 is lower, so that an inclined branch conveying surface 42 is formed, and after the object enters the branch conveying device 40, the object slides along the inclined branch conveying surface 42, so that no driving source is required to be added to the branch conveying device 40, and the energy-saving and environment-friendly effects are achieved.

The basic operation of a roll-transfer based flip-chip sorting apparatus 10 of the present invention is explained as follows:

in operation, the drive motor 26 rotates the rollers 25 to place articles on the conveyor surface 23 at the input end 21, at which time the rotating rollers 25 will urge the articles toward the output end 22. During this time, each weight sorter 30 will drive the respective flipping panel 27 to selectively perform the flipping motion, each flipping panel 27 having a different flipping force threshold, and the flipping panel 27 being capable of flipping only when the weight of the object is less than the flipping force threshold. Specifically, when an object moves above a certain flipping plate 27, if the weight of the object is less than the threshold value of the flipping force of the flipping plate 27, the flipping plate 27 completes the flipping action, so that the object is pushed into the corresponding branch conveyor 40, as shown in fig. 2; if the weight of the object is greater than the threshold value of the flipping force of the flipping board 27, the flipping board 27 cannot flip, i.e., the flipping board 27 cannot push the object, which will move above the next flipping board 27 as the drum 25 rotates. Thus, the articles can be classified according to their weight gradient, and the articles in the same branch conveyor 40 have the same weight gradient.

Up to this point, the basic operation of the roll-over sorter 10 based on roller transfer is described.

Because the turnover plate 27 is driven by the corresponding weight sorting device 30, the limit value of the turnover force is determined by the weight sorting device 30, in order to realize the basic working principle of the turnover sorting equipment 10 and simplify the internal structure of the weight sorting equipment, the invention makes special design on the structure of the weight sorting device 30, and the specific details are as follows:

as shown in fig. 5, the plurality of weight sorting devices 30 are in driving connection through a transmission shaft 31, the transmission shaft 31 is driven through a driving motor 32, and the driving motor 32 is fixedly installed on the fixed bracket 24;

as shown in fig. 7 and 8, each weight sorting apparatus 30 includes: a device base 100, an eccentric runner 200, a sliding rod 300, and a pressure movable assembly 400. The device base 100 is installed on the fixing bracket 24, the eccentric rotating wheel 200 is rotatably installed on the device base 100, the transmission shaft 31 drives the eccentric rotating wheel 200 to rotate, the sliding rod 300 is slidably installed on the device base 100, and the pressure movable assembly 400 connects the sliding rod 300 and the eccentric rotating wheel 200.

As shown in fig. 8, the pressure activity assembly 400 includes: a connecting wheel sleeve 410, a yaw connecting piece 420, a guide rod 430 and a sliding block 440. The connecting wheel sleeve 410 is sleeved on the eccentric rotating wheel 200, and the deflection connecting piece 420 is rotatably arranged at one end of the sliding rod 300; the connecting wheel sleeve 410 is provided with a wheel sleeve main connecting end 411 and a wheel sleeve auxiliary connecting end 412, the deflection connecting piece 420 is provided with a deflection main connecting end 421 and a deflection auxiliary connecting end 422, the guide rod 430 is provided with a connecting end 431, and the wheel sleeve main connecting end 411, the deflection main connecting end 421 and the connecting end 431 are hinged with each other; the sliding block 440 is slidably disposed on the guiding rod 430 through a telescopic elastic member 441, the sliding block 440 is connected to the wheel sleeve abutting end 412 through a first connecting rod 450, and the sliding block 440 is connected to the deflection abutting end 422 through a second connecting rod 460. Preferably, the telescopic elastic member 441 has a spring structure.

In the rotating process of the eccentric rotating wheel 200, the connecting wheel sleeve 410 is subjected to the interaction force of other parts and does not rotate along with the eccentric rotating wheel 200, and preferably, a bearing (not shown) is arranged on the inner side of the connecting wheel sleeve 410, so that the friction force between the eccentric rotating wheel 200 and the connecting wheel sleeve 410 can be effectively reduced.

During the operation of the weight sorting device 30, the pressure movable assembly 400 has two states, namely a stable state (as shown in fig. 9) and a movable state (as shown in fig. 10), when the pressure movable assembly 400 is in the stable state, the rotation of the eccentric wheel 200 drives the sliding rod 300 to perform the lifting motion through the pressure movable assembly 400, and during this period, the relative positions of the components of the pressure movable assembly 400 are not changed; when the pressure movable assembly 400 is in the movable state, the rotation of the eccentric wheel 200 will change the relative position between the parts of the pressure movable assembly 400, and the sliding rod 300 only slightly slides, even does not slide. The specific working principle will be explained below.

The state of the pressure movable assembly 400 is determined according to the relationship between the elastic force of the elastic member 441 and the pressure applied to the sliding rod 300, and when the pressure applied cannot overcome the elastic force, the pressure movable assembly 400 is in a stable state; when the pressure is applied to overcome the elastic force, the pressure activated assembly 400 is in an activated state. The sliding rod 300 is pressed to be related to the weight of the object, and the sliding rod 300 moves up and down to drive the turnover plate 27 to turn over, so that the elastic force of the elastic member 441 determines the limit value of the turnover force of the turnover plate 27.

The operation of the weight sorting device 30 will be explained with reference to the above structure:

for convenience of understanding, as shown in fig. 9, the process of the weight sorting apparatus 30 is divided into three states when the pressure movable assembly 400 is in the steady state, and denoted by reference numerals 1 to 3; as shown in fig. 10, when the pressure movable assembly 400 is in the active state, the process of the weight sorting apparatus 30 is also divided into three states and denoted by reference numerals 4 to 6;

taking a certain weight sorting device 30 as an example, the driving motor 32 is started, the transmission shaft 31 drives the eccentric rotating wheel 200 to rotate, at this time, no object is located above the weight sorting device 30, the sliding rod 300 of the weight sorting device 30 is not subjected to the pressure of the object, and the pressure cannot overcome the elastic force of the telescopic elastic member 441, at this time, the pressure movable assembly 400 is in a stable state, as shown in fig. 9, as the eccentric rotating wheel 200 rotates, the pressure movable assembly 400 only moves correspondingly and pushes the sliding rod 300 to move up and down, and further, the corresponding turnover plate 27 performs a turnover action;

when the object moves above the turnover plate 27, the turnover plate 27 is subject to the pressure of the object during the turnover action, and the pressure is transmitted to the sliding rod 300. Under the action of pressure, the connecting wheel sleeve 410 and the deflection connecting member 420 tend to deflect, and the first connecting rod 450 and the second connecting rod 460 tend to push the sliding block 440 to slide. However, since the sliding block 440 is also acted by the elastic force of the elastic member 441, the relationship between the elastic force and the pressure will affect the state of the pressure movable assembly 400;

if the elastic force of the elastic member 441 cannot be overcome by the pressure, as shown in fig. 9 with reference numerals 1 to 3, the sliding block 440 is firmly pulled by the elastic member 441 and cannot slide, so that the pressure movable assembly 400 is kept in a stable state, and during the rotation of the eccentric wheel 200, the pressure movable assembly 400 only moves correspondingly and pushes the sliding rod 300 to move up and down, and further, the turnover plate 27 performs a turnover action to push the object above the turnover plate 27 into the corresponding branch line conveying device 40;

if the pressure is applied to overcome the elastic force of the elastic member 441, as shown in fig. 10 with reference numbers 4 to 6, the pushing force applied to the sliding block 440 by the first connecting rod 450 and the second connecting rod 460 can overcome the elastic force of the elastic member 441, so that the sliding block 440 starts to slide. Due to the sliding of the sliding block 440, the connecting wheel sleeve 410 and the deflection connecting piece 420 perform corresponding deflection motion, and the relative distance between the connecting wheel sleeve 410 and the deflection connecting piece 420 is close, so that the rotation of the eccentric wheel 200 hardly pushes the sliding rod 300 to ascend and descend, i.e. the turnover plate 27 cannot be turned over, and the object moves to the upper side of the next turnover plate 27 along with the rotation of the roller 25.

The elastic force of the elastic member 441 is the initial elastic force of the elastic member 441. When the pressure is applied to overcome the initial elastic force of the elastic member 441, the sliding block 440 starts to slide, and as the sliding block 440 slides, the elastic member 441 is continuously stretched, so that the elastic force provided by the elastic member 441 to the sliding block 440 is continuously increased. In this way, the elastic force may increase to such a degree that the pressure cannot be overcome. However, when the elastic member 441 is stretched, the relative distance between the connecting wheel 410 and the deflecting link 420 is necessarily close to each other, and the distance for lifting the slide rod 300 is shortened, and further, the flipping plate 27 cannot be flipped at a sufficient angle, so that the flipping plate 27 cannot push the object into the branch conveyor 40.

It is further noted that the turning force limits of the plurality of turning plates 27 are not uniform. Whether the turnover plate 27 is turned over depends on whether the sliding rod 300 performs a lifting motion, and the condition for lifting the sliding rod 300 is that the pressure provided by the object cannot overcome the elastic force of the elastic member 441, i.e., the turnover plate 27 is capable of turning over only when the weight of the object is less than the turnover force limit value. To achieve a weight-gradient sorting of the articles, it is necessary for the flap plates 27 to have different turning force limits, and the flap plates 27 are arranged in a direction of transport along the main roller conveyor 20, in response to the turning force limits, from smaller to larger, i.e. the weight sorting device 30 with the greater spring force is closer to the output 22. This is because, if the weight sorting device 30 having a large elastic force is close to the input end 21, both the articles having a large weight and the articles having a small weight are pushed into the branch conveyor 40 by the flipping plate 27; only when the articles are arranged according to the limit value of the turning force from small to large, the articles can be better classified according to the weight gradient.

In one embodiment, as shown in fig. 11, an adjusting collar 432 is disposed on the guiding rod 430, a telescopic elastic member 441 connects the adjusting collar 432 and the sliding block 440, and a limit adjusting groove 433 engaged with the adjusting collar 432 is disposed on the guiding rod 430. The adjusting collar 432 can be locked on the guide rod 430 by matching the adjusting collar 432 with the limit adjusting groove 433; the position of the adjusting collar 432 can be adjusted according to actual needs, and the distance between the adjusting collar 432 and the sliding block 440 is increased or decreased, so as to adjust the elastic force of the telescopic elastic member 441.

In one embodiment, as shown in fig. 8, the connecting wheel sleeve 410 is provided with an anti-separation blocking piece 413, and the anti-separation blocking piece 413 is pressed on the eccentric rotating wheel 200, so that the connecting wheel sleeve 410 is prevented from being separated from the eccentric rotating wheel 200 in the rotating process.

In summary, the turnover type sorting equipment 10 based on roller conveying adopts a simple mechanical structure, so that the objects with different weights can be sorted according to the weight gradient, the cost of the sorting equipment is reduced, and the efficiency of object sorting is improved.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
