Description

Technical Field

[0001] The invention belongs to the technical field of logistics equipment, and in particular relates to a power component for a digital sorting machine. Background Art

[0002] Sorting machine refers to a "single-in, multiple-out" logistics conveying equipment, whose structure mainly includes input line, output line, steering mechanism, and various identification and control sensors. Among them, the input line and output line are generally various conveyor belts or conveyor rollers. The identification sensor judges each object to be sorted according to the sorting standard and conveys it to the corresponding sorting outlet, while the control sensor is used to control the entire conveying action, such as speed, angle, etc.

[0003] The most important thing is the steering mechanism, which plays a transitional role between feeding and discharging, ensuring the reliability of discharging operations in order and according to sorting standards. Its existing style is a section of conveyor belt or conveyor roller, with simple two sorting and discharging directions, namely one left and one right.

[0004] If you want to add more sorting and discharging directions, you can repeat the above structure and use the discharging roller of the previous step as the feeding roller of the next step. In this way, there will be four sorting and discharging directions. For example, you can sort out four different colored boxes of red, green, yellow and white in sequence.

[0005] However, the power components under this structural style will include a large number of rollers, motors, wires, etc., so it has many problems such as complex structure and high maintenance costs, and four sorting and discharging directions are sometimes still not enough.

[0006] A Chinese utility model patent with patent announcement number CN214298073U and announcement date 2021.09.28 discloses a roller conveyor device for logistics sorting, including a first conveying module, a transverse movement module is provided on one side of the output end of the first conveying module, the output end of the transverse movement module is connected to a second conveying module, and n third conveying modules are provided on one side of the transverse movement module. The second conveying module includes a first bracket, and a first lifting module is also provided in the middle of the inner side of the first bracket. The output end of the first lifting module is connected to a weighing module, and the weighing module is located between the two first rollers. A detection module is also provided on the first bracket.

[0007] However, the roller conveying device in the utility model patent still has a common roller as its steering structure, so there is a problem of relatively few sorting and discharging directions. It is not applicable when there are relatively more sorting types. In other words, if there are relatively more sorting and discharging directions, there are disadvantages of complex equipment structure and high cost. Summary of the invention

[0008] The present invention provides a power assembly for a digital sorting machine, which can achieve the purpose of effectively using the power assembly for steering sorting by arranging a support plate unit, a mounting rod unit, a wheat wheel unit and a driving wheel unit on a fixed frame.

[0009] The technical solution adopted by the present invention to solve the above-mentioned problem is: a power assembly for a digital sorting machine, including a fixed frame, and also including a wheat wheel unit located on the lower surface of the object to be sorted, a mounting rod unit used to sleeve and drive the wheat wheel unit, a driving wheel unit arranged at the end position of the mounting rod unit, and a support plate unit arranged on the inner side surface of the fixed frame and used to engage and place the mounting rod unit.

[0010] A further preferred technical solution is that the McWheel unit comprises a McWheel body and two annular limiting grooves respectively arranged on two side surfaces of the McWheel body.

[0011] A further preferred technical solution is that the mounting rod unit includes a regular hexagonal rod for sleeved onto the wheat wheel body, two threaded round rods respectively arranged on the two end faces of the regular hexagonal rod and clamped on the support plate unit, and a limiting circular tube sleeved on the regular hexagonal rod and located on the two annular limiting grooves relative to each other.

[0012] A further preferred technical solution is that the driving wheel unit includes an internal threaded ring arranged on the threaded round rod, an annular clamping groove arranged on the side of the internal threaded ring and used for clamping and installing the limiting round tube, and a driving belt arranged on the outer ring surface of the internal threaded ring.

[0013] A further preferred technical solution is that the support plate unit includes a fixed plate body arranged on the inner side of the fixed frame body, a rectangular groove opened downward from the upper surface of the fixed plate body, and a semicircular groove opened downward from the rectangular groove and used to place the threaded round rod.

[0014] A further preferred technical solution is that the driving wheel unit also includes an annular thread groove arranged on the outer end face of the internal thread ring, an axial channel arranged between the annular thread groove and the annular clamping groove, a lifting column arranged on the axial channel and used to clamp the limiting circular tube, an internal threaded tube body arranged on the annular thread groove and used to push the lifting column, and a lifting ring arranged on the end face of the lifting column and located in the annular clamping groove.

[0015] A further preferred technical solution is that the support plate unit also includes a mounting hole arranged on the fixed plate body and located above the internally threaded tube body, and a protruding column arranged on the mounting hole and used to limit and block the anti-drop operation above the internally threaded tube body.

[0016] A further preferred technical solution is that the rollers of the wheat wheel bodies on two adjacent mounting rod units are arranged opposite to each other.

[0017] A further preferred technical solution is that the driving belt is wound around the two spaced internal threaded rings, and the two spaced mounting rod units have the same rotation direction and equal rotation speed.

[0018] A further preferred technical solution is that: an internal threaded ring is provided on each of the two threaded round rods of the mounting rod unit, and the direction in which the driving belt drives the internal threaded ring is a tightening direction.

[0019] The present invention has the following advantages: first, the power assembly is used in the steering part of the sorting machine to control the rotation direction and rotation speed of the mounting rod unit, and theoretically has countless sorting and discharging directions; second, the wheat wheel structure used for steering sorting is firmly installed and can be quickly disassembled and assembled; third, the entire power assembly has high rotational operation stability, and the internal structure has its own locking and protection functions; fourth, the mounting rod unit has a waterproof function, and the entire power assembly can be used stably for a long time.

DETAILED DESCRIPTION

[0028] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0029] Example: As shown in the attached Figure 1-7 As shown, a power assembly for a digital sorting machine includes a fixed frame 11, a wheat wheel unit 1 located on the lower surface of the object a to be sorted, a mounting rod unit 2 for sleeve-engaging and driving the wheat wheel unit 1, a driving wheel unit 3 arranged at the end of the mounting rod unit 2, and a support plate unit 4 arranged on the inner side of the fixed frame 11 and used for engaging and placing the mounting rod unit 2.

[0030] In the prior art, the rollers of the Mech wheels are generally set at an inclined angle of 45°, so they have two equal speed fractions. When the mobile cart is equipped with four Mech wheels that are symmetrical in pairs, an all-round moving effect on the horizontal plane can be obtained. In this process, it is only necessary to adjust and coordinate the rotation direction and rotation speed of each Mech wheel.

[0031] Therefore, in this embodiment, the originally moving wheat wheel is fixed, and the originally fixed ground is replaced by the lower surface of the object a to be sorted. The object a to be sorted can be transported in any direction on the horizontal plane through the same wheat wheel adjustment control method, ensuring that the power component has the advantage of multiple sorting and discharging directions as a steering mechanism. Generally, a "M-shaped" structure can set up seven sorting and discharging directions except for one feeding direction, which has great economic value in today's increasingly complex and diversified logistics operations.

[0032] Among them, a pair of the mounting rod units 2 is the smallest unit of the power component, and the final combined speed is controllable and adjustable inside the smallest unit. Therefore, the object a to be sorted is fed along the length direction of the mounting rod unit 2 to ensure that it is pressed on two or four of the mounting rod units 2, ensuring that the conveying force is evenly applied on the lower surface of the object a to be sorted, and the combined speed is the combined force.

[0033] In addition, the driving wheel unit 3 is used to controllably drive the wheat wheel unit 1, and the supporting plate unit 4 is used to install the wheat wheel unit 1 to ensure that the wheat wheel unit 1 can be stably rotated and transported.

[0034] Finally, the word "digital" mentioned in the present invention refers to the determination of the sorting standard, the rotation direction and rotation speed of the power component, and the connection between the sensor for determination and the driving motor of the power component. A control system and a control program can be set up in accordance with the prior art to ensure that the objects a to be sorted can be discharged in an orderly manner in the above-mentioned seven sorting and discharging directions.

[0035] The McWheel unit 1 includes a McWheel body 101 and two annular limiting grooves 102 respectively arranged on two side surfaces of the McWheel body 101 .

[0036] In this embodiment, the wheel body 101 is an existing structure, including a regular hexagonal opening, a wheel body and a circle of inclined rollers on the outside, and the annular limiting groove 102 is used for the subsequent installation of the mounting rod unit 2.

[0037] The mounting rod unit 2 includes a regular hexagonal rod 201 for sleeved on the wheat wheel body 101, two threaded round rods 202 respectively arranged on the two end faces of the regular hexagonal rod 201 and clamped on the support plate unit 4, and a limiting circular tube 203 sleeved on the regular hexagonal rod 201 and located on the two annular limiting grooves 102 opposite to each other.

[0038] In this embodiment, the regular hexagonal rod 201 is inserted into the regular hexagonal wheat wheel opening, which has the advantage of almost no slipping during rotational drive compared to the socket connection method of the circular opening, and the limiting circular tube 203 has the following two functions: first, it supports the two driving wheel units 3 and all the wheat wheel bodies 101 to ensure that the entire structure does not rock back and forth on the regular hexagonal rod 201, so that the wheat wheel body 101 can stably rotate and drive the object a to be sorted; second, the limiting circular tube 203 itself is made of plastic, which can protect the regular hexagonal rod 201 and the threaded circular rod 202 from water and dust, which is particularly useful when sorting seafood products such as water.

[0039] The driving wheel unit 3 includes an internal threaded ring 301 arranged on the threaded round rod 202, an annular clamping groove 302 arranged on the side of the internal threaded ring 301 and used for clamping and installing the limiting round tube 203, and a driving belt 303 arranged on the outer ring surface of the internal threaded ring 301.

[0040] In this embodiment, the number of the mounting rod units 2 is set to eight, so a driving belt 303 is required to be set between the first and third, the third and fifth, the fifth and seventh, the second and fourth, the fourth and sixth, and the sixth and eighth to ensure that a single driving motor can drive all the odd or even numbered mounting rod units 2.

[0041] It should be noted that, as mentioned above, the smallest unit of the mounting rod unit 2 is a pair of two adjacent ones, so even if the number of the mounting rod units 2 in pairs is large, they are simply copied, and the principle of driving and conveying the lower surface of the object a to be sorted is the same.

[0042] For example, Figure 6 As shown, when the object a to be sorted is loaded along Va, V1 and V2 have a canceling effect of the component speeds in the vertical loading direction and a superimposing effect of the component speeds in the opposite loading direction, so the loading action of the object a to be sorted can be stopped first.

[0043] Then it is as attached Figure 7 As shown, the directions of V3 and V1 are the same, and the directions of V4 and V2 are opposite. At this time, for the stopped object a to be sorted, there is an effect of canceling the upper and lower speeds and superimposing the right speeds in the figure. Therefore, the material can be sorted and discharged to the right. For the object a to be sorted, it can be discharged even if it turns left 90°.

[0044] And just beside Figure 7 In the figure, if the speed of V4 is greater than V3, the superposition of the upper and lower component speeds still has a downward combined speed. At this time, the superposition of the right component speed is added, so the object a to be sorted is discharged in a certain direction in the lower right corner of the figure. This is the advantage of the so-called theoretically countless sorting and discharging directions in this application.

[0045] The support plate unit 4 includes a fixed plate body 401 disposed on the inner side of the fixed frame body 11 , a rectangular groove 402 opened downward from the upper surface of the fixed plate body 401 , and a semicircular groove 403 opened downward from the rectangular groove 402 and used to accommodate the threaded round rod 202 .

[0046] In this embodiment, a section of the threaded round rod 202 mounted on the semicircular slot 403 is not provided with threads, and the semicircular slot 403 can ensure that the entire mounting rod unit 2 will not fall and can rotate stably all the time.

[0047] The driving wheel unit 3 also includes an annular thread groove 304 arranged on the outer end face of the internal thread ring 301, an axial channel 305 arranged between the annular thread groove 304 and the annular clamping groove 302, a lifting column 306 arranged on the axial channel 305 and used to clamp the limiting circular tube 203, an internal threaded tube body 307 arranged on the annular thread groove 304 and used to push the lifting column 306, and a lifting ring 308 arranged on the end face of the lifting column 306 and located in the annular clamping groove 302.

[0048] In this embodiment, the two internal threaded rings 301 and a row of all the McWheel bodies 101 as a whole need to be fixed on the regular hexagonal rod 201, so the limiting circular tube 203 for lifting is introduced.

[0049] However, after being used for a period of time, the limiting circular tube 203 is bound to shrink and deform to a certain extent, so the entire internal thread ring 301 and the wheat wheel body 101 become loose, and the force conveying the lower surface of the object a to be sorted becomes asymmetric, which eventually causes the discharge direction of the object a to be sorted to deviate disorderly and uncontrollably. The most common problem is that it hits the guardrails on both sides of the sorting machine, which is a very serious problem.

[0050] Therefore, compared with the regular hexagonal rod 201, the McWh main body 101 cannot move, and the deformed and shortened limiting tube 203 requires a length reinforcement structure, that is, the internal threaded tube body 307 rotates inward, and the lifting column 306 and the lifting ring 308 as a whole lift the limiting tube 203, so that all the limiting tubes 203 and all the McWh main bodies 101 are locked and fixed again.

[0051] The support plate unit 4 further includes a mounting hole 404 disposed on the fixing plate body 401 and located above the internally threaded tube body 307 , and a protruding column 405 disposed on the mounting hole 404 and used for limiting and blocking the anti-drop operation above the internally threaded tube body 307 .

[0052] In this embodiment, the internal threaded tube body 307 also has a second function, namely: the protruding column 405 and the internal threaded tube body 307 overlap each other in the vertical direction, with the former being on the top and the latter being on the bottom. In this way, as long as the protruding column 405 is not pulled out, the internal threaded tube body 307, together with the driving wheel unit 3 and the mounting rod unit 2, will not accidentally fall out of the semicircular groove 403, which is very safe and efficient.

[0053] Of course, the length of the protruding column 405 cannot be too large, and it is necessary to ensure that it can be effectively screwed in and out between the internal threaded ring 301 and the fixed plate body 401 and on the mounting hole 404. The mounting hole 404 is also the location where the screws for mounting the fixed plate body 401 are set.

[0054] The rollers of the wheat wheel bodies 101 on two adjacent mounting rod units 2 are arranged opposite to each other.

[0055] In this embodiment, the two symmetrical rows of rollers of the wheat wheel body 101 can form a total of four rotation direction combinations on the lower surface of the object a to be sorted, that is, each of the two rows has two rotation directions, which are combined to form four directions, and finally ensure a total of eight conveying directions, one of which is the loading direction. In this way, in line with the above, seven discharging directions can be set, and the overall shape is a "M-shape".

[0056] The above direction combination plus the adjustment between different speeds can form countless final discharge directions in theory.

[0057] The driving belt 303 is wound around the two spaced internal thread rings 301 , and the two spaced mounting rod units 2 have the same rotation direction and equal rotation speed.

[0058] In this embodiment, the two spaced mounting rod units 2 are the two units at the same position in the minimum unit, and therefore require the same driving belt 303 for synchronous driving.

[0059] An internal thread ring 301 is respectively provided on the two threaded round rods 202 of the mounting rod unit 2, and the driving belt 303 drives the internal thread ring 301 in a tightening direction.

[0060] In this embodiment, the mounting rod unit 2 needs to have two rotation directions, but the internal threaded ring 301 has only one tightening direction. Therefore, when a single internal threaded ring 301 is responsible for driving in two rotation directions, it is easy to loosen it, which is very dangerous. Therefore, an internal threaded ring 301 is provided at both ends of a single mounting rod unit 2 to ensure that the internal threaded ring 301 is tightened in both rotation directions of the mounting rod unit 2.

[0061] Therefore, in the end, even if the entire power assembly has eight, ten, or twelve mounting rod units 2, only four unidirectional motors are required, that is, two on each side of the mounting rod unit 2. The two motors on the same side respectively drive the mounting rod units 2 in odd order and the mounting rod units 2 in even order. This is a relatively simple and reliable embodiment of the power assembly structure in the present invention.

[0062] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
