Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and particularly relates to a high-speed grouping and lane-dividing device. Background Art

[0002] Before the final packaging of articles, they first need to be arranged at equal intervals, and then it is convenient to carry out lane division subsequently. The usual equal-spacing adjusting device includes a clamping and conveying component and an equal-spacing adjusting component that are sequentially arranged along the conveying path direction and correspondingly arranged on both sides of the conveying path, which respectively realize the clamping and conveying of articles and the equal-spacing adjustment. Since their functions are different, currently, usually one driving motor is respectively set as the power source. However, since the operating rhythms of the clamping and conveying component and the equal-spacing adjusting component must be coordinated to achieve the connection between clamping and conveying and equal-spacing adjustment, independent driving and control have higher requirements for the performance of the driving motor and the control accuracy.

[0003] The angles of some articles during the conveying process are different from the angles when they are placed in the packing box during the final packaging. Therefore, angle adjustment is required. Before adjustment, it is necessary to first pause the conveying of the articles, and then change the angles of the articles through a manipulator or the like. After completion, the conveying is continued, and the angle adjustment during the continuous conveying process cannot be realized.

[0004] In the existing lane-dividing device, it is necessary to first pause the conveying of the articles, and then carry out lane division through a manipulator or a push plate or the like. After the lane division is completed, the conveying is continued, and continuous high-speed lane division cannot be realized. Summary of the Invention

[0026] The technical solution adopted by the present invention has the following beneficial effects:

[0027] In the clamping and conveying and equal-spacing adjusting device, the clamping and conveying component and the equal-spacing adjusting component respectively achieve the clamping and conveying of articles and the equal-spacing adjustment. Moreover, the lateral conveyor belt of the clamping and conveying component and the lateral driving component of the equal-spacing adjusting component are driven by the same conveying driving motor, so the requirements for the performance and control accuracy of the driving motor are not too high. This not only helps to ensure the coordination of the operation rhythms of the clamping and conveying component and the equal-spacing adjusting component, but also, compared with using driving motors separately, one driving motor can be reduced, which is also conducive to cost reduction.

[0028] The conveying device capable of adjusting the placing angle of articles can adjust the placing angle of articles during the conveying process, facilitating subsequent lane division and packaging. The first carrying component continuously runs along the annular path of the first conveying component without interruption during the process of adjusting the article angle. And the process of adjusting the article angle is achieved by the cooperation of the steering guide post and the steering track to drive two of the first carrying sliders to slide towards the opposite sides of the first conveying rod. This cooperation method also enables the first carrying component to run at a relatively fast speed. Therefore, the adjustment speed is accelerated and the adjustment efficiency is improved.

[0029] In the continuous high-speed lane division device, the second carrying component continuously runs along the annular path of the second conveying component without interruption during the lane division process. And the lane division process is achieved by the cooperation of the lane division driving column and the lane division track to drive the second carrying platform assembly. This cooperation method also enables the second carrying component to run at a relatively fast speed. Therefore, the lane division speed is accelerated and the lane division efficiency is improved.

Detailed implementation manners

[0057] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0058] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0059] The terms used in the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. For example, terms indicating orientation or positional relationships such as "front", "rear", "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0060] In the present invention, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more, unless otherwise clearly defined.

[0062] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0063] Refer to Figures 1 to 22As shown in the figure, a high-speed packet lane-dividing device includes a clamping and conveying and equal-spacing adjusting device 1, a conveying device 2 for adjusting the placing angle of an article, and a continuous high-speed lane-dividing device 3. Among them, the clamping and conveying and equal-spacing adjusting device 1 realizes the equal-spacing adjustment of the article 100 during the process of clamping and conveying the article 100. Therefore, the articles are arranged in a row at equal intervals through the clamping and conveying and equal-spacing adjusting device 1, and then the articles arranged in a row at equal intervals remain arranged at equal intervals when being conveyed on the conveying device 2 for adjusting the placing angle of the article; the conveying device 2 for adjusting the placing angle of the article is used to adjust the placing angle of the article 100 during the conveying process; the continuous high-speed lane-dividing device 3 divides a row of articles 100 arranged at equal intervals into at least two columns of articles 100 arranged at equal intervals.

[0064] The clamping and conveying and equal-spacing adjusting device 1, the conveying device 2 for adjusting the placing angle of the article, and the continuous high-speed lane-dividing device 3 can be arranged continuously. Of course, it can be understood that for articles that do not need to adjust the placing angle, the conveying device 2 for adjusting the placing angle of the article may not be provided, and the clamping and conveying and equal-spacing adjusting device 1 and the continuous high-speed lane-dividing device 3 are arranged continuously, and the articles arranged in a row at equal intervals output from the clamping and conveying and equal-spacing adjusting device 1 directly enter the continuous high-speed lane-dividing device 3 for lane division.

[0065] As Figures 1 to 5 shown in the figure, on the clamping and conveying and equal-spacing adjusting device 1, the article 100 is conveyed forward along a straight conveying path and equal-spacing adjustment is performed during the conveying process. The clamping and conveying and equal-spacing adjusting device includes clamping and conveying components 12 and equal-spacing adjusting components 13 that are arranged in sequence along the straight conveying path direction and are correspondingly arranged on both sides of the conveying path, and a bracket 11 for mounting the clamping and conveying components 12 and the equal-spacing adjusting components 13. Among them, the clamping and conveying component 12 is provided with a lateral conveyor belt 121, and a clamping and conveying channel is formed between the lateral conveyor belts 121 of the clamping and conveying components 12 on both sides. The equal-spacing adjusting component 13 is provided with a lateral driving assembly and a push head 134. The push head 134 is mounted on the lateral driving assembly, and an equal-spacing adjusting conveying channel is formed between the lateral driving assemblies of the equal-spacing adjusting components 13 on both sides. The lateral driving assembly drives the push head 134 to move unidirectionally along the straight conveying path direction. The lateral conveyor belt 121 and the lateral driving assembly are driven by the same conveying driving motor 125.

[0066] It can be understood that the downstream part of the clamping and conveying channel needs to overlap with the upstream part of the equal-spacing adjusting conveying channel for a certain length, and the specific overlapping length is approximately the length of one article. In this way, the clamping and conveying components 12 on both sides convey the article into the equal-spacing adjusting conveying channel, so that the push head 134 can act on the rear end of the article 100, thereby pushing the article to move along the equal-spacing adjusting conveying channel.

[0067] As an implementation manner, the lateral driving assembly includes a pushing chain 131, a driving sprocket 132 for driving the pushing chain 131, and a driven sprocket 133 engaged with the pushing chain 131. A plurality of driven sprockets 133 can be provided to form a closed-loop movement path for the pushing chain 131. The pushing head 134 is installed on one of the chain links of the chain. At least two pushing heads 134 are arranged along the circumferential direction of the chain, and the pushing heads 134 are arranged at equal intervals on the chain. Therefore, while the pushing heads 134 push the article 100 to move along the equally-spaced adjustable conveying channel, an equally-spaced distribution mode is formed. It can be understood that the lateral driving assembly is not limited to the above manner. For example, a synchronous belt or the like can also be used.

[0068] In this implementation manner, the pushing chain 131 has a closed-loop movement path with a right-angled trapezoidal structure. A total of four sprockets are provided, including a driving sprocket 132 and three driven sprockets 133, which are correspondingly distributed at the four corner positions of the right-angled trapezoid. Among them, the driving sprocket is located at the corner on one side of the upper base right angle. When the pushing chain 131 passes through the waist on one side of the straight edge, an equally-spaced adjustable conveying channel is formed between the two pushing chains 131 on both sides. In addition, a guard plate can be provided on the outer side of the pushing chain, including a fixed guard plate on the outer side and a movable guard plate that can be turned up and down and is hinged to the upper side of the fixed guard plate through a hinge.

[0069] In order to drive the lateral conveyor belt 121 and the pushing chain 131 simultaneously, the conveying driving motor 125 is connected to the driving shaft 122. The lateral conveyor belt 121 is connected with a driving pulley, and both the driving pulley and the driving sprocket are installed on the driving shaft 122.

[0070] In this implementation manner, the lateral conveyor belt 121 has a closed-loop movement path with a triangular structure. The lateral conveyor belt 121 is also connected with a driven pulley 123. One driving pulley and two driven pulleys 123 are respectively located at the three corner positions of the triangle, and a tensioning pulley 124 is correspondingly provided in the middle of one side.

[0071] In order to ensure the clamping of the article, the lateral conveyor belt 121 is arranged in a two-layer structure in the up-and-down direction. The upper-layer lateral conveyor belt clamps the upper part of the article, and the lower-layer lateral conveyor belt clamps the lower part of the article. The pushing chain 131 only needs to be arranged in one layer and is located at the middle position of the height between the upper and lower layers of the lateral conveyor belts 121. The pushing head acts on the middle part of the article. In this way, while realizing the driving of the lateral conveyor belt 121 and the pushing chain 131 by the same conveying driving motor 125, it is possible to make the downstream part of the clamping conveying channel coincide with the upstream part of the equally-spaced adjustable conveying channel.

[0072] In order to adapt to different articles, the widths of the clamping and conveying channel and the equal-spacing adjusting and conveying channel need to be adjusted. Therefore, the clamping and conveying components 12 and the equal-spacing adjusting components 13 on both sides of the conveying path are correspondingly arranged on the lateral sliding brackets 112. Correspondingly, a lateral fixed bracket 111 is provided below the lateral sliding bracket, and the lateral fixed brackets 111 on both sides are connected by an intermediate connecting piece and fixed as a whole. A linear slide rail 113 is provided between the lateral sliding bracket 112 and the lateral fixed bracket 111, and the lateral sliding bracket 112 is connected with a linear drive. Therefore, the linear drives on both sides act synchronously to drive the clamping and conveying components 12 and the equal-spacing adjusting components 13 on both sides to act synchronously, moving relatively or towards each other, so as to realize the synchronous adjustment of the widths of the clamping and conveying channel and the equal-spacing adjusting and conveying channel.

[0073] In this embodiment, the linear drive includes an adjusting drive motor 114 and a lead screw nut mechanism. The lead screw nut mechanism is connected with the lateral sliding bracket 112. The adjusting drive motor 114 drives the lead screw of the lead screw nut mechanism to rotate, driving the nut to move linearly. Since the lateral sliding bracket 112 is connected with the nut, it also moves linearly along with the nut. It can be understood that the linear drive can also be replaced by a cylinder, an electric cylinder, etc.

[0074] Since the lateral sliding bracket is long and heavy, in order to realize the synchronous movement of the front part and the rear part, one adjusting drive motor and two speed changers 115 are provided for the linear drive. The two speed changers 115 are arranged side by side in the front and rear direction and both are provided with input shafts extending in the front and rear directions. An intermediate transmission shaft is connected between the two input shafts. The output shaft of the adjusting drive motor 114 is connected with the input shaft of one of the speed changers, and the output shaft of the speed changer is connected with the lead screw nut mechanism.

[0075] Take Figure 2 as an example shown. The article to be pushed is an aluminum can that has been packaged and arranged in a rectangular array. Since the outer shape of the aluminum can is cylindrical, the push head 134 is provided with an arc-shaped recess that matches the arc of the edge of the article.

[0076] Still taking the aluminum can as an example, before entering the continuous high-speed lane-dividing device 3, the length direction of the article is consistent with the conveying direction. After adjusting the placing angle of the article, the length direction of the article is perpendicular to the conveying direction. Therefore, a conveying device 2 for adjusting the placing angle of the article is provided. As Figures 6 to 13 shown, the conveying device 2 for adjusting the placing angle of the article includes a first conveying component 21, a first bearing component 22 and a steering component 23.

[0077] Among them, the first conveying component 21 includes a plurality of first conveying rods 212 that move unidirectionally along an annular path. The first conveying rods 212 extend in the left-right direction, and the annular path has a horizontally extending horizontal conveying path.

[0078] The first bearing member 22 includes a plurality of first bearing platform assemblies 221 continuously distributed along the annular path of the first conveying member. The first bearing platform assembly 221 is composed of a plurality of first bearing sliders connected in sequence along its extending direction, and the first bearing sliders are slidably connected to the first conveying rod 212. Convex columns 22112 are provided at the rectangular diagonal positions of the articles corresponding to the bearing surfaces of two first bearing sliders spaced apart from each other, and steering guide columns 22111 are provided on the bottom surfaces of these two first bearing sliders. These two first bearing sliders are herein referred to as steering bearing sliders 2211, and the other first bearing sliders are herein referred to as fixed bearing sliders 2212. The steering bearing sliders 2211 can slide along the axial direction of the first conveying rod 212, and the fixed bearing sliders 2212 do not slide relative to the first conveying rod 212.

[0079] The steering member 23 includes two steering tracks 231 slidably connected to the corresponding steering guide columns 22111 on the two steering bearing sliders 2211. The steering track 231 has an inclined section 2312 inclined to the horizontal conveying path. By guiding the steering guide columns 22111 through the inclined section 2312, the two steering bearing sliders 2211 are driven to slide to the opposite sides of the first conveying rod 212, and the articles are driven to turn through the cooperation of the convex columns 22112 on the two steering bearing sliders. In this embodiment, since the article is rectangular, the convex columns 22112 on the two steering bearing sliders act on the two diagonal side surfaces of the article correspondingly and move in two opposite directions at the same time, so as to push the article to turn. Finally, the rotation angle is 90 degrees. It can be understood that for different articles, the positions of the convex columns 22112 on the steering bearing sliders can be changed, and the shapes of the convex columns can be cylindrical, frustum-shaped, or other shapes.

[0080] In this embodiment, the first conveying component 21 further includes two first conveying chains 211 arranged side by side left and right. The first conveying chains 211 are installed on sprockets and are unfolded to form an annular structure with both ends being arc-shaped and the middle being straight. The sprockets are installed on the first sprocket shafts 214, and one of the first sprocket shafts is driven by the first conveying motor 213, specifically, it can drive the first sprocket shaft after passing through a speed reducer. Correspondingly, several first bearing platform components move unidirectionally in a circular path along with several first conveying rods following the chains. This circular movement path includes a straight movement path I, an arc movement path I, a straight movement path II, and an arc movement path II. The straight movement path II is located on the opposite side of the straight movement path I, and the straight movement path I and the straight movement path II are relatively parallel. The arc movement path II is located on the opposite side of the arc movement path I. The straight movement path I, the arc movement path I, the straight movement path II, and the arc movement path II are connected in sequence to form a closed circular movement path. Among them, the straight movement path I is located on the upper side, the straight movement path II is located on the lower side, and the arc movement path II and the arc movement path I are located on the front side and the rear side respectively.

[0081] The first conveying rod 212 can be set as a hollow rod. The first conveying rod is rotatably sleeved on the core rod, and both ends of the core rod are correspondingly connected to the links of the two chains.

[0082] In order to realize the lateral sliding of the steering bearing slider 2211 relative to the fixed bearing slider 2212, first sliding grooves 2213 are provided on the front and rear side surfaces of the first bearing slider. The first sliding grooves of adjacent two first bearing sliders are combined and are in sliding fit with the first conveying rod. Therefore, the adjacent steering bearing slider 2211 and the fixed bearing slider 2212 are in sliding fit with the same first conveying rod 212.

[0083] It can be understood that adjacent two items on the first bearing component 22 are arranged at equal intervals and have an interval space, and thus they will not interfere with each other during the steering process. Therefore, the fixed bearing slider 2212 includes a middle fixed bearing slider located between two steering bearing sliders 2211 and edge fixed bearing sliders located on the front and rear sides of the first bearing platform component 221. The middle fixed bearing slider plays a main bearing role, and the number of the middle fixed bearing slider and the edge fixed bearing sliders can be changed according to the size of the item.

[0084] In order to form a stable support for the item while reducing the friction during the steering process of the item, a first arc-shaped groove is provided on the bearing surface of the middle fixed bearing slider, and a first support column 22122 is connected in the first arc-shaped groove. The first support column 22122 is a cylinder and protrudes from the first arc-shaped groove. Therefore, the item is supported by multiple spaced first support columns 22122, and multi-point stable support can be formed.

[0085] Further, the steering track 231 further includes a first straight section 2311 connected to the first end of the inclined section 2312 and extending along the horizontal conveying path direction, and a second straight section 2313 connected to the second end of the inclined section 2312 and extending along the horizontal conveying path direction. Before entering the inclined section, the steering guide post 22111 cooperates with the first straight section 2311, and the steering carrier slider 2211 and the fixed carrier slider 2212 remain relatively stationary, that is, the steering carrier slider 2211 still remains flush with the fixed carrier slider 2212. During the movement along the inclined section 2213, the steering carrier slider 2211 slides laterally. When reaching the end of the inclined section 2213, the steering carrier slider 2211 laterally moves to the maximum lateral position. After disengaging from the inclined section 2213, the steering guide post 22111 cooperates with the second straight section 2313 and still remains in the maximum lateral position.

[0086] Since not all items need to adjust the placement angle, when there is no need to adjust the placement angle, if the clamping and conveying and equal-spacing adjusting device 1 is directly connected to the continuous high-speed lane-dividing device 3, the conveying device 2 that can adjust the placement angle of the item needs to be removed. This is less efficient and not convenient enough. In order to keep the item at the original angle during the conveyance through the conveying device 2 that can adjust the placement angle of the item without removing the conveying device 2 that can adjust the placement angle of the item. The steering member 23 further includes an intermediate straight track 232. The bottom surfaces of all the fixed carrier sliders 2212, except for the steering carrier slider 2211 provided with the convex post, in the first carrier platform assembly are provided with straight guide posts 22121, and the straight guide posts 22121 cooperate with the intermediate straight track 232. At the same time, the steering member 23 further includes side straight tracks 233 provided on both sides of the intermediate straight track 232. The side straight tracks 233 are provided in the extending direction of the first straight section. A conversion track 2314 for realizing the on-off between the first straight section and the inclined section and the straight track is provided between the first straight section 2311, the inclined section 2312, and the side straight track 233. When the conversion track 2314 connects the first straight section 2311 and the side straight track 233, that is, cuts off the connection between the first straight section 2311 and the inclined section 2312, after the steering guide post 22111 disengages from the first straight section 2311, it cooperates with the side straight track 233. During this process, the steering carrier slider 2211 does not slide laterally, so the item passes through the conveying device 2 that can adjust the placement angle of the item and is conveyed at the original angle. When the conversion track 2314 connects the first straight section 2311 and the inclined section 2312, that is, cuts off the connection between the first straight section 2311 and the side straight track 233, after the steering guide post 22111 disengages from the first straight section 2311, it cooperates with the inclined section 2312, and the placement angle of the item can be adjusted.

[0087] To achieve the rapid conversion of the conversion track 2314, the conversion track 2314 is rotatably connected to a pin shaft and driven by a conversion cylinder 2315. Or it can also be driven by other drivers, such as an electric cylinder.

[0088] When the first carrying platform assembly 221 passes through the straight motion path I, if the steering carrying slider 2211 slides laterally to adjust the placement angle of the article, then after leaving the inclined section 2213, the steering guide post 22111 cooperates with the second straight section 2313 and still remains in the maximum lateral position. When the first carrying platform assembly 221 passes through the arc motion path I, the straight motion path II, and the arc motion path II in sequence and before entering the straight motion path I, the steering carrying slider 2211 must return to its original position and be flush with other fixed carrying sliders 2212 in order to adjust the article angle again. To achieve this purpose, as Figure 12 and Figure 13 shown, steering tracks 231, intermediate straight tracks 232, and side straight tracks 233 are correspondingly provided on both the upper and lower sides of the steering member 23, and the positions and extension directions of the upper and lower sides are exactly the same. Of course, it can be understood that the conversion track 2314 does not need to be provided on the lower side, and other structures are the same.

[0089] Furthermore, first transition tracks 234 are provided on both the front and rear sides of the steering member 23 for realizing the transitional connection between the upper and lower tracks. The first transition tracks 234 are installed on the first sprocket shaft 214. Among them, three first transition tracks are provided on the front side, correspondingly connected to two steering tracks and the intermediate straight track, and five first transition tracks are provided on the rear side, correspondingly connected to two steering tracks, two side straight tracks, and the intermediate straight track. The first transition track 234 has an arc section and straight sections that are parallel up and down and connected to both ends of the arc section. The front straight section is connected to the first straight section 2311, and the rear straight section is connected to the second straight section 2313. In this way, if the steering carrying slider 2211 slides laterally when the first carrying platform assembly 221 passes through the straight motion path I, then when passing through the straight motion path II, the steering carrying slider 2211 will return to its original position again, and so on, in a reciprocating cycle.

[0090] As Figures 14 to 22 shown, the continuous high-speed lane-dividing device 3 includes a second conveying member 31, a second carrying member 32, and a lane-dividing member 33.

[0091] The second conveying member 31 includes a plurality of second conveying rods 312 that move unidirectionally along an annular path. The annular path has a horizontally extending horizontal conveying path, and at least two conveying channels are arranged side by side on the horizontal conveying path.

[0092] The second bearing member 32 includes a plurality of second bearing platform assemblies 321 continuously distributed along the annular path of the second conveying member. The second bearing platform assembly 321 is composed of a plurality of second bearing sliders, and adjacent two second bearing sliders are movably connected. The second bearing slider is slidably connected with the second conveying rod 312. One of the second bearing sliders is provided with a lane dividing driving column 32111. The second bearing slider provided with the lane dividing driving column 32111 here is called the active bearing slider 3211, and the remaining second bearing sliders are called driven bearing sliders 3212. All the driven bearing sliders 3212 are driven by the active bearing slider 3211 to slide along the second conveying rod 312. Since adjacent two second bearing sliders are movably connected, when moving along the annular path, they can move relatively and form a certain angle along the annular path. At the same time, all the second bearing sliders of the second bearing platform assembly 321 can also slide axially along the second conveying rod 312.

[0093] In order to realize the sliding of the second bearing sliders in the second bearing platform assembly 321, similar to the chute structure of the first bearing sliders in the first bearing member, second chutes are also provided on the front and rear sides of the second bearing sliders. The second chutes of adjacent two second bearing sliders are combined and slidably cooperate with the second conveying rod. And in order to ensure the synchronous lateral sliding of all the second bearing sliders in the second bearing platform assembly 321, as Figure 17 shown, adjacent two second bearing sliders in the second bearing platform assembly 321 are fitted and connected through a concave-convex structure 3213. In this way, adjacent two second bearing sliders can move relatively. At the same time, through the fitting connection of the concave-convex structure 3213, when any one of the second bearing sliders slides laterally along the axial direction of the second conveying rod 312, it can drive the other second bearing slider to slide laterally along the axial direction of the second conveying rod 312.

[0094] In this embodiment, among adjacent two second bearing sliders, one is provided with a rectangular protrusion, and the other is provided with a rectangular groove. The protrusion is embedded in the groove to form a concave-convex structure 3213 by cooperation. In the second bearing platform assembly 321, on the front and rear sides of the middle second bearing slider, one side is provided with a protrusion and the other side is provided with a groove, so that all the middle second bearing sliders are fitted and connected through the concave-convex structure 3213. In the second bearing platform assembly 321, for the two second bearing sliders corresponding to the front and rear sides, only the side that is connected to other second bearing sliders is provided with a groove or a protrusion, and the side that is connected to the adjacent second bearing platform assembly 321 is not provided with a groove or a protrusion. In this way, adjacent two second bearing sliders between adjacent two second bearing platform assemblies are not directly connected, but only slidably cooperate with the same second conveying rod through the second chute, and adjacent two second bearing platform assemblies 321 will not form a linkage action.

[0095] It can be understood that only one active load-bearing slider 3211 needs to be provided. As long as one active load-bearing slider 3211 slides laterally, it can drive all the second load-bearing sliders in the second load-bearing platform assembly to slide laterally synchronously. Of course, more than one active load-bearing slider 3211 can also be provided.

[0096] In order to form a stable support for the article, similar to the bearing surface structure of the intermediate fixed load-bearing slider, a second arc-shaped groove is provided on the bearing surface of the second load-bearing slider, and a second support column is connected in the second arc-shaped groove. The second support column is a cylinder and protrudes from the second arc-shaped groove. Therefore, the article is supported by multiple second support columns arranged at intervals, and a multi-point stable support can be formed.

[0097] In this embodiment, the second conveying component 31 further includes two second conveying chains 311 arranged side by side left and right. The second conveying chains 311 are installed on the sprockets and are unfolded to form an annular structure with arc-shaped ends and a straight middle. The sprockets are installed on the second sprocket shafts 314, and one of the second sprocket shafts is driven by the second conveying motor 313. Specifically, it can be driven after passing through a speed reducer and then driving the second sprocket shaft. Correspondingly, several second load-bearing platform assemblies move unidirectionally in a circular path along with several second conveying rods following the chains. This circular movement path includes a straight movement path I, an arc movement path I, a straight movement path II, and an arc movement path II. The straight movement path II is located on the opposite side of the straight movement path I, and the straight movement path I and the straight movement path II are relatively parallel. The arc movement path II is located on the opposite side of the arc movement path I. The straight movement path I, the arc movement path I, the straight movement path II, and the arc movement path II are connected in sequence to form a closed circular movement path. Among them, the straight movement path I is located on the upper side, the straight movement path II is located on the lower side, and the arc movement path II and the arc movement path I are located on the front side and the rear side respectively.

[0098] The second conveying rod 312 can be set as a hollow rod. The second conveying rod is rotationally sleeved on the core rod, and the two ends of the core rod are correspondingly connected to the links of the two chains.

[0099] As Figures 19 to 22 shown, the lane-changing component 33 includes a lane-changing track 331 slidably connected to the lane-changing driving column 32111. The lane-changing track 331 includes an inclined section 3311 inclined to the horizontal conveying path. By guiding the movement of the lane-changing driving column 3211 through the inclined section 3311, the entire second load-bearing platform assembly 321 is driven to move laterally, so as to change the conveying channel of the article on the second load-bearing platform assembly 321.

[0100] During the lane splitting process, a part of the second load-bearing platform assembly 321 can remain without lateral sliding, and another part of the second load-bearing platform assembly 321 can laterally slide to one side of the horizontal conveying path, so that the originally single row of items can be split into two rows. Of course, a more preferred way is that a part of the second load-bearing platform assembly 321 laterally slides to one side of the horizontal conveying path, and another part of the second load-bearing platform assembly laterally slides to one side of the horizontal conveying path. In this way, within a limited width, a sufficient spacing can be maintained between the two rows of items after lane splitting. Therefore, correspondingly, lane splitting tracks 331 are provided on both the left and right sides of the lane splitting component 33, that is, the left lane splitting track cooperates with the lane splitting drive columns 32111 of a part of the second load-bearing platform assembly 321, and the right lane splitting track cooperates with the lane splitting drive columns 32111 of another part of the second load-bearing platform assembly 321.

[0101] During the lane splitting process, all the second load-bearing platform assemblies 321 continue to continuously convey items. Therefore, the lane splitting process is continuous, and high-speed lane splitting can be achieved.

[0102] Furthermore, it is also necessary to consider the situation where the continuous high-speed lane splitting device 3 does not perform lane splitting. A straight track 332 is provided in the middle of the lane splitting component. The first ends of the lane splitting tracks 331 and the straight track 332 are connected to a first turnout track 334, and the on / off of the lane splitting tracks 331 and the straight track 332 is achieved through the first turnout track 334. When lane splitting is not required, the first turnout track 334 is connected to the straight track 332, and at the same time, the lane splitting tracks 331 are cut off. When lane splitting is required, the first turnout track 334 is connected to the lane splitting tracks 331, and at the same time, the straight track 332 is cut off. Moreover, the first turnout track 334 switches between the left lane splitting track and the right lane splitting track, thereby determining whether the items on the second load-bearing platform assembly 321 are split into the left conveying channel or the right conveying channel.

[0103] In order to achieve the fast and accurate switching of the first turnout track 334, the first turnout track 334 is rotatably connected to a pin shaft and is driven by a turnout electric cylinder 335. Or it can also be driven by other drivers.

[0104] Further, in order to adjust the spacing between the two columns of articles after lane splitting, the lane splitting track 331 further includes at least two bifurcated segments 3313 connected to the second end of the inclined segment 3311. Taking two bifurcated segments as an example, one of the bifurcated segments 3313 extends straight along the straight movement path I, corresponding to a relatively narrow spacing between the two columns of articles after lane splitting. A part of the other bifurcated segment 331 is arranged in the extending direction of the inclined segment 3311, and the other part extends straight along the straight movement path I, corresponding to a relatively wide spacing between the two columns of articles after lane splitting. A second switch track 3312 is provided between at least two bifurcated segments 3313 and the second end of the inclined segment 3311. The on-off of the bifurcated segment entrance is realized through the second switch track 3312, that is, one bifurcated segment is connected and the other bifurcated segment is cut off. If the second switch track 3312 is currently connected to one of the above bifurcated segments 3313, corresponding to a relatively narrow spacing between the two columns of articles after lane splitting, and if it is necessary to change to a relatively wide spacing between the two columns of articles after lane splitting, the second switch track 3312 is connected to the other bifurcated segment 3313 of the above. When the lane splitting driving column 32111 runs to the straight part of the bifurcated segment 3313, the second bearing platform assembly 321 moves laterally to the position after lane splitting, that is, the lane splitting of the two columns of articles is realized.

[0105] In order to achieve the rapid conversion of the second switch track 3312, the second switch track 3312 is rotatably connected to a pin shaft and is driven by a switch cylinder 3314. Or it can also be driven by other drivers, such as an electric cylinder.

[0106] When the second bearing platform assembly 321 passes through the straight movement path I, if the second bearing platform assembly 321 slides laterally to split the articles, then after the lane splitting is completed, the second bearing platform assembly 321 still remains in the position after lane splitting. When the second bearing platform assembly 321 passes through the arc movement path I, the straight movement path II, and the arc movement path II in sequence and before entering the straight movement path I, the second bearing platform assembly 321 must return to its original position before it can split the lanes again. To achieve this purpose, as Figure 19 and Figure 22As shown, lane-dividing tracks 331 and straight tracks 332 are correspondingly provided on the upper and lower sides of the lane-dividing component 33, and the positions and extension directions of the upper and lower sides are exactly the same. Of course, it can be understood that the first switch track 334 and the second switch track 3312 do not need to be provided on the lower side, and other structures are the same. At the same time, second transition tracks 333 are provided on the front and rear sides of the lane-dividing component 33. The second transition tracks 333 are installed on the second sprocket shaft 314. Among them, one second transition track is provided on the front side, and several second transition tracks are provided on the rear side. The second transition track 333 has an arc section and straight sections that are vertically parallel and connected to both ends of the arc section. The upper straight section on the front side is connected to the first switch track, and the upper straight section on the rear side is connected to the bifurcated section and the straight track. In this way, if the second load-bearing platform assembly slides laterally when passing through the straight movement path I, then when passing through the straight movement path II, the second load-bearing platform assembly will return to its original position. In this way, it circulates reciprocally.

[0107] As described above, it is only the specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
