Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1-8, a transportation structure for a digital sorting machine comprises a fixed frame unit 1, a rotating rod unit 2 with two ends respectively inserted on two opposite inner side surfaces of the fixed frame unit 1, a wheat wheel unit 3 sleeved on the rotating rod unit 2 and used for changing the discharge direction of lifted objects to be sorted by changing the rotating direction and adjusting the rotating speed, and a connecting belt unit 4 arranged on the rotating rod unit 2 and externally connected with a driving motor.

In this embodiment, 6, 8, 10 or 12 rotating rod units 2 are arranged in one fixed frame unit 1, a plurality of wheat wheel units 3 are fixedly mounted on each rotating rod unit 2, and finally the connecting belt unit 4 drives the rotating rod units 2, so that the wheat wheel units 3 have the functions of variable rotating directions and adjustable rotating speeds.

In this way, flexible and variable resultant speeds, i.e. resultant forces for conveying, can be obtained on the lower surface of the objects to be sorted, and the directions and the magnitudes of the resultant forces can be changed, so that the final discharging operation in different directions, namely the so-called sorting, can be realized.

The wheat wheel unit 3 comprises wheat wheel main bodies 301, the rotary rod units 2 are arranged in pairs, the rollers of the wheat wheel main bodies 301 on the adjacent two rotary rod units 2 are symmetrically arranged, and the feeding direction of objects to be sorted is parallel to the length direction of the rotary rod units 2.

In this embodiment, the wheel body 301 is a conventional structure, and includes a wheel body and an outer ring of rollers 301a, and the inclination angle of the rollers 301a is usually 45 °, so that the component speeds, or component forces, of V1 and V2 are all at the decomposition position of 45 °.

In addition, the rollers 301a of the wheat wheel main bodies 301 on two adjacent rotating rod units 2 are symmetrically arranged, that is, the combination speeds of the two adjacent rollers 301a are respectively two, namely, positive rotation and reverse rotation, which can be called as + V1, -V1, + V2 and-V2, so that two rollers are combined in pairs, and finally, four combination speeds are provided on the lower surface of the object to be sorted, corresponding to four different discharging directions of the object to be sorted, namely, left turning 90 degrees, right turning 90 degrees, straight going and reverse going.

Generally, the reverse mode is not adopted, so that the steering component in the embodiment finally has at least 3 discharging sorting directions, for example, a batch of boxes which have three colors of red, green and blue and are mixed together, and the transportation structure comprising the steering component in the embodiment can be used for realizing the sorting purpose. In the process, the necessary color recognition device, control circuit, some existing control software and the like are installed on the transportation structure.

Finally, when the feeding direction of the objects to be sorted and the length direction of the rotating rod unit 2 are parallel to each other, the lower surfaces of the objects to be sorted have low efficiency, or the component forces are bilaterally symmetrical, so that the objects to be sorted are not easy to rotate.

However, when the feeding direction is perpendicular to the length direction of the rotating rod unit 2, the mutually inefficient component speeds, or component forces, are offset back and forth, so that the objects to be sorted are prone to the problem of rotation, which needs to be avoided and is the key point of the present application.

The fixed frame unit 1 comprises a rectangular frame 101, wherein a feeding roller a is arranged on one of the frame plates of the rectangular frame 101, which is provided with the rotating rod unit 2, and discharging rollers b are arranged on the other three frame plates.

In this embodiment, if the objects to be sorted are placed downwards on the wheat wheel main body 301, there are four discharging directions as described above, but in the real conveying and sorting operation, the objects to be sorted are all conveyed by rollers or conveyor belts, and therefore, one direction, namely the feeding rollers a, is occupied, so that the remaining three sides correspond to three discharging rollers b in total, and the transportation structure is ensured to have at least three-way or three-stage sorting function.

More importantly, however, the operation modes of the + V1, -V1, + V2 and-V2 only relate to the change of the rotating direction, and the adjustment of the rotating speed is not mentioned. Thus, in theory, the original rotation between + V1 and + V2, for example, is: the partial velocities perpendicular to the rotary bar unit 2 are completely offset, the partial velocities parallel to the rotary bar unit 2 are directly added, and the items to be sorted are directly fed back to the feeding roller a, which is not available.

At this time, only the speed of + V1 or + V2 is reduced, so that a new discharging direction inclined at a small angle with the feeding roller a can be finally obtained, and the new discharging direction can be named as 'discharging after being rotated by 140 degrees'.

Therefore, the high efficiency of the theoretically infinite discharging directions is the creativity of the application.

The fixing frame unit 1 further includes protruding plates 102 provided on two opposite inner sides of the rectangular frame 101, and a circular hole 103 provided on the protruding plates 102 and for inserting and mounting the rotating rod unit 2.

In this embodiment, the protruding plate 102 is provided with a circular hole 103, which is a mounting seat for rotating the rotating rod unit 2, and two mounting seats are respectively arranged at two ends of the rotating rod unit 2.

The rotating rod unit 2 includes a threaded cylinder 201 provided on the circular hole 103, and a prismatic rod body 202 provided between the two threaded cylinders 201; the wheat wheel unit 3 further comprises an on-wheel circular hole 302 and an on-wheel screw hole 303 which are arranged on the wheat wheel main body 301, and a limiting tube body portion 304 which is arranged in the on-wheel circular hole 302, connected with the on-wheel screw hole 303 and used for being sleeved with the prismatic rod body 202.

In this embodiment, the wheel main body 301, the wheel circular hole 302 and the wheel screw hole 303 are the structure of the existing wheel, and the limiting tube 304 functions as: the wheat wheel is provided with a square or regular-hexagon hole, and the prismatic rod body 202 with the square or regular-hexagon section is matched, so that an annular limiting fixing effect can be obtained additionally on the basis of sleeving the wheat wheel and the rod body.

In addition, the thread section of the thread cylinder 201 is only partially opened, so that the thread section does not touch the circular hole 103.

The stopper tube body 304 includes a fixing plate 304a provided on the side of the wheel main body 301, a regular polygonal hole 304b provided on the fixing plate 304a, a regular polygonal tube 304c provided on the side of the fixing plate 304a and inserted into the wheel-mounted circular hole 302 with its inner hole aligned with the regular polygonal hole 304b, and a fixing bolt 304d provided on the fixing plate 304a and for coupling with the wheel-mounted screw hole 303.

In this embodiment, the entire limiting tube body 304 is made of engineering plastic or light aluminum, the inner hole of the regular polygonal tube 304c must be a square or a regular hexagon matched with the prismatic rod 202, and the shape of the outer side of the tube body is not limited as long as the tube body can be inserted into the round hole 302 on the wheel.

In addition, the length of the regular polygonal tube 304c needs to be relatively large to ensure a sufficient socket engagement with the prism-shaped rod 202.

The limiting pipe body 304 further comprises a first annular groove 304e arranged on the side surface of the fixing plate 304a and used for accommodating the exposed tail part of all the fixing bolts 304d, and an outer sleeve body 304f arranged on the first annular groove 304e and used for jacking up and limiting operations between the adjacent wheat wheel main bodies 301 and between the wheat wheel main body 301 on the side and the connecting belt unit 4.

In this embodiment, the outer sleeve body 304f has several advantages.

First, the fixing bolt 304d is held in the first annular groove 304e, so that the fixing bolt 304d is prevented from loosening in a short time, and even if loosened, the fixing bolt does not fall off and is lost.

Secondly, if the outer sleeve body 304f is not provided, the wheat wheel only has an annular limiting effect and lacks the limiting effect in the length direction of the prismatic rod body 202, so that the wheat wheel can swing left and right to influence the stability of the static friction force application action after supporting and lifting the lower surface of the object to be sorted.

If the outer sleeve body 304f is to be replaced, it is very inefficient and cumbersome to install screws on the regular polygonal tube 304c, connecting the prismatic rod 202.

And thirdly, n wheat wheels and n +1 outer sleeve bodies 304f are all simply sleeved on the prism-shaped rod body 202, and two ends of the wheat wheel units are fixed by two connecting belt units 4 in a screwed manner, so that the whole wheat wheel unit 3 has a quick-release function, and all the wheat wheels and the outer sleeve bodies 304f slide down only by taking down one connecting belt unit 4, which is very convenient.

Fourth, the objects to be sorted may drip down, and the threaded cylinder 201 and the prismatic rod 202 are generally made of steel rods due to the use strength, so the plastic outer sleeve 304f also has the function of protecting the threaded cylinder 201 and the prismatic rod 202 from water, and certainly, can also be dustproof.

The connection belt unit 4 includes two internal thread rings 401 respectively disposed on the two threaded cylinders 201, a driving belt 402 fitted over the two spaced internal thread rings 401, and two belt ring grooves 403 disposed on the outer circumferential surface of the internal thread rings 401.

In this embodiment, the smallest repeating unit of all the rotating rod units 2 of even number is a pair, so for example, the left one of each pair of the rotating rod units 2 needs to be linked together, and similarly, all the rotating rod units 2 on the right side need to be linked together, so that the internal thread ring 401 and the driving belt 402 are provided, and all the rotating rod units 2 are also driven at intervals.

Furthermore, it is more important that the rotating rod unit 2 is required to rotate in the opposite direction, so that if only one internally threaded ring 401 is used for driving, it is dangerous that the internally threaded ring 401 is unscrewed in one of the rotating directions, and therefore, in this embodiment, one internally threaded ring 401 is provided on each of the two rotating rod units 2, so as to ensure that the internally threaded ring 401 is screwed in both rotating directions.

Finally, as can be understood in colloquial terms, all of the rotating rod units 2, i.e., all of the internally threaded rings 401, have an odd number of the internally threaded rings 401 on one side that share a drive motor, an even number of the internally threaded rings 401 that share a drive motor, and the other side that is repeated, the steering assembly requires only four drive motors, and is a relatively small motor, since the power is directly input to the article to be sorted, and it is not necessary to rotate the other parts of the steering assembly, which is very efficient.

The connection band unit 4 further includes a ball groove 404 provided on an opposite outer end surface of the female screw ring 401, a ball body 405 provided on the ball groove 404 for rolling friction on the projection plate 102, and a second annular groove 406 provided on an opposite inner end surface of the female screw ring 401 for insertion-mounting of the outer sleeve body 304 f. The connecting band unit 4 further includes an internal threaded hole 407 disposed between the ball groove 404 and the second annular groove 406, a first stud 408 disposed on the internal threaded hole 407 and protruding into the ball groove 404, an arc-shaped groove plate 409 disposed on an end surface of the first stud 408 and adapted to snap-fit the ball body 405, and a second stud 410 disposed on the internal threaded hole 407 and protruding into the second annular groove 406 and adapted to clamp the outer sleeve body 304 f.

Finally, the ball bodies 405 in this embodiment are adapted to roll on the side of the protruding plate 102 to ensure relatively low resistance, while the outer sleeve body 304f is also continuously clamped in the second annular groove 406 to ensure that the entire connecting band unit 4 can be stably rotated for a long time.

However, after a period of use, the protruding plate 102 is liable to be worn and recessed, and the outer sleeve body 304f is liable to have a small shrinkage deformation, so that the rolling friction portion, the second annular groove 406 and the first annular groove 304e are liable to be loosened, which affects the use quality of the whole steering component.

The arc-shaped groove body plate 409 which can be extended out in an outward rotating manner and the second stud 410 are introduced to compensate the wear deformation and shrinkage deformation, wherein the first stud 408 with the arc-shaped groove body plate 409 can push the ball body 405 out properly, and has a relatively outer dimension without affecting the rotating and rolling of the ball body, and the second stud 410 with the support plate thereof can clamp the outer sleeve body 304f again after being protruded, and clamps all the outer sleeve bodies 304f in a row.

Finally, the positions and the number of the internal threaded holes 407 are aligned with the ball grooves 404, and the support plates on the arc-shaped groove body plate 409 and the second stud 410 can be correspondingly provided with a cross-shaped groove for rotation.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
