The clamping, conveying and equal-spacing adjusting device 1 realizes equal-spacing adjustment of the articles 100 in the process of clamping and conveying the articles 100, so that the articles are arranged in a row at equal spacing through the clamping, conveying and equal-spacing adjusting device 1, and then the articles arranged in the row at equal spacing are kept in the equal-spacing arrangement when being conveyed on the conveying device 2 with the article placing angle adjustable; the conveying device 2 with an adjustable article placing angle is used for adjusting the placing angle of the article 100 in the conveying process; the continuous high-speed lane divider 3 divides a row of equally spaced articles 100 into at least two equally spaced rows of articles 100.

The clamping conveying and equal-interval adjusting device 1, the conveying device 2 capable of adjusting the article placing angle and the continuous high-speed lane dividing device 3 can be continuously arranged. Of course, it is understood that, for an article whose placement angle does not need to be adjusted, the conveying device 2 whose placement angle is adjustable may not be provided, the gripping conveying and equal-pitch adjusting device 1 and the continuous high-speed lane dividing device 3 may be provided continuously, and the articles that are output from the gripping conveying and equal-pitch adjusting device 1 and arranged in a row at equal pitches directly enter the continuous high-speed lane dividing device 3 to be divided.

The clamping conveying and equal-spacing adjusting device comprises a clamping conveying component 12 and an equal-spacing adjusting component 13 which are sequentially arranged along the direction of a straight conveying path and are correspondingly arranged on two sides of the conveying path, and a bracket 11 for mounting the clamping conveying component 12 and the equal-spacing adjusting component 13. The clamping and conveying component 12 is provided with a lateral conveying belt 121, and a clamping and conveying channel is formed between the lateral conveying belts 121 of the clamping and conveying components 12 on two sides. Equidistant adjusting part 13 is equipped with side direction drive assembly and cuts somebody's hair 134, cut somebody's hair 134 and install on side direction drive assembly, form equidistant regulation conveying channel between the side direction drive assembly of both sides equidistant adjusting part 13, side direction drive assembly drives cuts somebody's hair 134 along straight transport path direction unidirectional movement. The lateral conveyor belt 121 and the lateral drive assembly are driven by the same conveyor drive motor 125.

It will be appreciated that the downstream portion of the gripping conveyor path and the upstream portion of the equal-spacing adjusting conveyor path need to overlap by a length of about one article. Thus, the gripping and conveying members 12 on both sides convey the article into the equal-interval adjusting conveying path, so that the pushing head 134 can act on the rear end of the article 100 to push the article along the equal-interval adjusting conveying path.

As an embodiment, the lateral driving assembly includes a push chain 131 and a driving sprocket 132 driving the push chain 131, and a driven sprocket 133 engaged with the push chain 131, and the driven sprocket 133 may be provided in plurality such that the push chain 131 forms a closed loop movement path. The pushing head 134 is installed on one of the chain links, at least two pushing heads 134 are arranged along the circumferential direction of the chain, and the pushing heads 134 are arranged on the chain at equal intervals, so that the pushing heads 134 form an equal-interval distribution mode while pushing the articles 100 to move along the equal-interval adjusting conveying channel. It will be appreciated that the lateral drive assembly is not limited to the above, and for example, a timing belt or the like may be used.

In this embodiment, the driving chain 131 has a closed loop motion path with a right trapezoid structure, and four chain wheels are provided, including a driving chain wheel 132 and three driven chain wheels 133, and are correspondingly distributed at four corners of the right trapezoid, wherein the driving chain wheel is located at a corner on one side of the upper bottom right angle. When the pushing chains 131 pass through the straight-side waist, an equal-interval adjusting conveying channel is formed between the pushing chains 131 on the two sides. In addition, the outer side of the pushing chain can be provided with a guard plate which comprises a fixed guard plate on the outer side and a movable guard plate which is hinged to the upper side of the fixed guard plate through a hinge and can be turned up and down.

In order to simultaneously drive the side conveyor belt 121 and the push chain 131, the conveyor driving motor 125 is connected to the driving shaft 122, the side conveyor belt 121 is connected to the driving pulley, and the driving pulley and the driving sprocket are mounted on the driving shaft 122.

In this embodiment, the lateral conveyor belt 121 has a closed loop movement path with a triangular structure, the lateral conveyor belt 121 is further connected with a driven pulley 123, one driving pulley and two driven pulleys 123 are respectively located at three corner positions of the triangle, and a tensioning pulley 124 is correspondingly arranged in the middle of one of the three corners.

In order to ensure the clamping of the articles, the lateral conveyor 121 is configured in a two-layer structure in the vertical direction, the upper lateral conveyor clamps the upper portion of the articles, and the lower lateral conveyor clamps the lower portion of the articles. The pushing chain 131 only needs to be provided with one layer and is positioned in the middle position of the lateral conveying belts 121 on the upper layer and the lower layer, and the pushing head acts on the middle of the article. In this way, it is possible to overlap the downstream portion of the nip conveying path and the upstream portion of the equal pitch adjusting conveying path while driving the side conveying belt 121 and the push chain 131 by the same conveying driving motor 125.

To accommodate different articles, the width of the gripping conveyor channel and the equidistant adjustment conveyor channel need to be adjusted. Therefore, the gripping and conveying members 12 and the equal-pitch adjusting members 13 on both sides of the conveying path are correspondingly provided on the lateral sliding brackets 112. The lateral fixing brackets 111 are correspondingly arranged below the lateral sliding brackets, and the lateral fixing brackets 111 at the two sides are connected through an intermediate connecting piece and fixed into a whole. A linear slide rail 113 is arranged between the lateral sliding support 112 and the lateral fixing support 111, and the lateral sliding support 112 is connected with a linear driver. Therefore, the linear drivers on the two sides synchronously act to drive the clamping conveying component 12 and the equal-spacing adjusting component 13 on the two sides to synchronously act and move relatively or oppositely, and the width synchronous adjustment of the clamping conveying channel and the equal-spacing adjusting conveying channel is realized.

In this embodiment, the linear actuator includes an adjusting driving motor 114 and a screw-nut mechanism, the screw-nut mechanism is connected to the lateral sliding support 112, the adjusting driving motor 114 drives a screw of the screw-nut mechanism to rotate, and drives a nut to move linearly, and the lateral sliding support 112 is connected to the nut, so that the lateral sliding support moves linearly with the nut. It will be appreciated that the linear actuator may be replaced by an air cylinder, an electric cylinder, or the like.

Because the lateral sliding support is long in length and heavy in weight, in order to realize synchronous motion of the front part and the rear part, the linear driver is provided with an adjusting driving motor and two speed changers 115, the two speed changers 115 are arranged side by side in the front and at the back and are respectively provided with an input shaft extending in the front and at the back, an intermediate transmission shaft is connected between the two input shafts, an output shaft of the adjusting driving motor 114 is connected with an input shaft of one of the speed changers, and an output shaft of the speed changer is connected with a screw-nut mechanism.

Taking the example shown in fig. 2, the pushed article is a packaged pop can arranged in a rectangular array, and the pushing head 134 is provided with an arc-shaped concave part matched with the arc-shaped edge of the article due to the cylindrical shape of the pop can.

Still taking the pop-top 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, and after the article placing angle is adjusted, the length direction of the article is perpendicular to the conveying direction. Thus, the conveying device 2 capable of adjusting the article placement angle is provided. As shown in fig. 6 to 13, the conveyor 2 capable of adjusting the article placement angle includes a first conveying member 21, a first carrying member 22, and a turning member 23.

The first conveying member 21 includes a plurality of first conveying rods 212 moving in a single direction along a circular path, the first conveying rods 212 extending in the left-right direction, and the circular path having a horizontal conveying path extending horizontally.

The first bearing part 22 comprises a plurality of first bearing platform assemblies 221 which are continuously distributed along the annular path of the first conveying part, each first bearing platform assembly 221 is composed of a plurality of first bearing sliding blocks which are sequentially connected along the extending direction of the first bearing platform assembly, and each first bearing sliding block is connected with the corresponding first conveying rod 212 in a sliding mode. Convex columns 22112 are arranged on the bearing surfaces of two first bearing sliders arranged at intervals and corresponding to the opposite corners of the article, and steering guide columns 22111 are arranged on the bottom surfaces of the two first bearing sliders, the two first bearing sliders are called as steering bearing sliders 2211, and the other first bearing sliders are called as fixed bearing sliders 2212. The turn-carrying slider 2211 can slide in the axial direction of the first transport rod 212, and the fixed carrying slider 2212 does not slide with respect to the first transport rod 212.

The diverting member 23 comprises two diverting rails 231 slidably connected to corresponding diverting guide columns 22111 on the two diverting carrying sliders 2211, the diverting rails 231 have inclined sections 2312 inclined to the horizontal conveying path, the guiding of the diverting guide columns 22111 by the inclined sections 2312 drives the two diverting carrying sliders 2211 to slide to the opposite sides of the first conveying rod 212, and the article is diverted by the cooperation of the convex columns 22112 on the two diverting carrying sliders. In this embodiment, since the article is rectangular, the two steering bearing slider upper protruding columns 22112 correspondingly act on two opposite angle side surfaces of the article, and move in two opposite directions simultaneously, so as to push the article to steer, and the final rotation angle is 90 degrees. It will be appreciated that the location of the post 22112 on the steering carrier block may vary for different articles, and that the shape of the post may be cylindrical, frustoconical, or other shapes.

In this embodiment, the first conveying component 21 further includes two first conveying chains 211 arranged side by side in the left and right direction, the first conveying chains 211 are installed on the chain wheel and unfolded to form an annular structure with two ends in an arc shape and a straight middle part, the chain wheel is installed on a first chain wheel shaft 214, one of the first chain wheel shaft is driven by a first conveying motor 213, and specifically, the first chain wheel shaft can be driven after passing through a speed reducer. Correspondingly, the first bearing platform assemblies and the first conveying rods move along the chain in a one-way circulating mode along the annular path along the chain, the annular movement path comprises 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, the straight movement path I and the straight movement path II are relatively parallel, and the arc movement path II is located on the opposite side of the arc movement path I. The straight motion path I, the arc motion path I, the straight motion path II and the arc motion path II are connected in sequence to form a closed annular motion path. Wherein, straight motion route I is located the upside, straight motion route II is located the downside, and arc motion route II and arc motion route I are located front side and rear side respectively.

The first conveying rod 212 may be configured as a hollow rod, and the first conveying rod rotates and is sleeved on a core rod, and two ends of the core rod are correspondingly connected with the chain links of the two chains.

In order to realize the lateral sliding of the steering bearing slide block 2211 relative to the fixed bearing slide block 2212, the front and rear side surfaces of the first bearing slide block are provided with first sliding grooves 2213, and the first sliding grooves of two adjacent first bearing slide blocks are combined and matched with the first conveying rod in a sliding manner. Thus, adjacent diverter carriage 2211 and stationary carriage 2212 are slidably engaged with the same first conveyor bar 212.

It will be appreciated that adjacent articles on the first load bearing member 22 are equally spaced and have a spacing therebetween and thus do not interfere with each other during a turn. The fixed bearing slide 2212 thus comprises a middle fixed bearing slide located between the two steering bearing slides 2211 and edge fixed bearing slides located on the front and rear sides of the first bearing platform assembly 221. The middle fixed bearing slide block plays a main bearing role, and the number of the middle fixed bearing slide block and the number of the edge fixed bearing slide blocks can be changed according to the size of an article.

In order to reduce the friction force during the steering process of the article while forming stable support for the article, a first arc-shaped groove is formed in 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 columns 22122 are cylindrical and protrude out of the first arc-shaped groove, so that the article is supported by the plurality of first support columns 22122 arranged at intervals, and a multi-point stable support can be formed.

Further, the turning track 231 further includes a first straight section 2311 connected to a first end of the inclined section 2312 and extending in the horizontal conveying path direction, and a second straight section 2313 connected to a second end of the inclined section 2312 and extending in the horizontal conveying path direction. Before entering the inclined section, the turn guide column 22111 engages the first straight section 2311, and the turn bearing block 2211 remains relatively stationary with respect to the fixed bearing block 2212, i.e. the turn bearing block 2211 remains flush with the fixed bearing block 2212. During movement along the inclined segment 2213, the diverter carriage 2211 slides laterally, to the end of the inclined segment 2213, the diverter carriage 2211 moves laterally to a maximum lateral position, and after disengaging the inclined segment 2213, the diverter guide post 22111 engages the second straight segment 2313, remaining in the maximum lateral position.

Since the placing angle is not required to be adjusted for all the articles, if the holding conveying and equal-interval adjusting device 1 is directly connected to the continuous high-speed lane dividing device 3, the conveying device 2 capable of adjusting the placing angle of the articles needs to be removed. Therefore, the efficiency is low and the use is inconvenient. In order to keep the article conveyed at the original angle when the article passes through the article placing angle adjustable conveyor 2 without removing the article placing angle adjustable conveyor 2. The steering component 23 further includes a middle straight track 232, the bottom surfaces of all the fixed bearing sliders 2212 except the steering bearing slider 2211 provided with the convex columns in the first bearing platform assembly are provided with straight guide columns 22121, and the straight guide columns 22121 are matched with the middle straight track 232. Meanwhile, the steering component 23 further includes lateral straight rails 233 disposed on two sides of the middle straight rail 232, the lateral straight rails 233 are disposed in the extending direction of the first straight section, and a switching rail 2314 for switching between the first straight section and the inclined section and between the first straight section 2311, the inclined section 2312 and the lateral straight rails 233 is disposed between the first straight section and the inclined section. When the transition track 2314 connects the first straight section 2311 and the lateral straight track 233, i.e., cuts off the connection between the first straight section 2311 and the inclined section 2312, the turn direction guide column 22111 is disengaged from the first straight section 2311 and then engages with the lateral straight track 233, during which the turn direction bearing slider 2211 does not slide laterally, so that the articles are conveyed at the original angle by the conveyor 2 with the article placement angle adjustable. When the switching track 2314 connects the first straight section 2311 and the inclined section 2312, i.e., cuts off the connection between the first straight section 2311 and the lateral straight track 233, the turn direction guide post 22111 is disengaged from the first straight section 2311 and then is engaged with the inclined section 2312, so that the article placement angle can be adjusted.

To achieve a fast switching of the switching track 2314, the switching track 2314 is rotatably connected to the pin and driven by a switching cylinder 2315. Or may be driven by other actuators, such as electric cylinders.

If the diverter carriage 2211 is slid laterally for article placement angle adjustment as the first carriage assembly 221 traverses the straight path of travel i, the diverter guide 22111 engages the second straight section 2313 after disengaging the angled section 2213 and remains in the maximum lateral position. After the first carriage assembly 221 passes through the arc-shaped movement path i, the straight movement path ii, and the arc-shaped movement path ii in sequence, before entering the straight movement path i, the steering carriage 2211 must return to the original position again, and be flush with the other fixed carriage 2212, so that the angle of the article can be adjusted again. To achieve this, as shown in fig. 12 and 13, the upper side and the lower side of the turning member 23 are respectively provided with a turning rail 231, a middle straight rail 232 and a side straight rail 233, and the positions and extending directions of the upper side and the lower side are completely identical. Of course, it is understood that the underside need not be provided with transition tracks 2314, and that other configurations are consistent.

Further, the front side and the rear side of the steering component 23 are provided with first transition tracks 234 for realizing transition connection between the upper side track and the lower side track, and the first transition tracks 234 are installed on the first sprocket shaft 214. The front side is provided with three first transition tracks which are correspondingly connected with the two steering tracks and the middle straight track, and the rear side is provided with five first transition tracks which are correspondingly connected with the two steering tracks, the two side straight tracks and the middle straight track. The first transition track 234 has an arc-shaped section and a straight section which is connected to both ends of the arc-shaped section and is parallel to the arc-shaped section up and down, the straight section on the front side is connected to the first straight section 2311, and the straight section on the rear side is connected to the second straight section 2313. Thus, if the steering carriage 2211 slides laterally while traveling along the straight path i, the steering carriage 2211 returns back again while traveling along the straight path ii, and the cycle is repeated.

As shown in fig. 14 to 22, the continuous high-speed lane device 3 includes a second conveying member 31, a second carrier member 32, and a lane member 33.

One of the second bearing sliders is provided with a lane driving post 32111. Here, the second bearing slider provided with the lane driving column 32111 is referred to as a driving bearing slider 3211, the remaining second bearing sliders are referred to as driven bearing sliders 3212, and all the driven bearing sliders 3212 are driven by the driving bearing slider 3211 to slide along the second conveying rod 312. Because two adjacent second bearing sliders are movably connected, when moving along the annular path, the two second bearing sliders can move relatively and form a certain included angle along the annular path, and simultaneously, all the second bearing sliders of the second bearing platform assembly 321 can axially slide along the second conveying rod 312 together.

In order to realize the sliding of the second bearing slider in the second bearing platform assembly 321, the structure of the sliding groove is the same as that of the sliding groove of the first bearing slider in the first bearing part, the front side surface and the rear side surface of the second bearing slider are also provided with second sliding grooves, and the second sliding grooves of two adjacent second bearing sliders are combined and matched with the second conveying rod in a sliding manner. In order to ensure that all the second bearing sliders in the second bearing platform assembly 321 slide laterally and synchronously, as shown in fig. 17, two adjacent second bearing sliders in the second bearing platform assembly 321 are connected through a concave-convex structure 3213 in an embedded manner, so that the two adjacent second bearing sliders can move relatively and are connected through a concave-convex structure 3213 in an embedded manner, and when any one of the second bearing sliders slides laterally along the axial direction of the second conveying rod 312, the other second bearing slider can be driven to slide laterally along the axial direction of the second conveying rod 312.

In this embodiment, one of the two adjacent second bearing sliders is provided with a rectangular protrusion, the other one of the two adjacent second bearing sliders is provided with a rectangular groove, and the protrusion is embedded into the groove to form the concave-convex structure 3213 in a matching manner. In the second bearing platform assembly 321, the middle second bearing slider is arranged on the front side and the rear side, wherein one side of the middle second bearing slider is provided with a protrusion, and the other side of the middle second bearing slider is provided with a groove, so that all the middle second bearing sliders are connected in an embedded manner through the concave-convex structure 3213. In the second bearing platform assembly 321, two second bearing sliding blocks corresponding to the front side and the rear side are provided with grooves or bulges only on one side connected with other second bearing sliding blocks, and one side connected with the adjacent second bearing platform assembly 321 is not provided with grooves or bulges, so that the two adjacent second bearing sliding blocks in the two adjacent second bearing platform assemblies are not directly connected, and only through the sliding fit of the second sliding grooves and the same second conveying rod, the two adjacent second bearing platform assemblies 321 can not form linkage action.

It can be understood that only one active bearing slider 3211 is provided, and as long as one active bearing slider 3211 slides laterally, all the second bearing sliders in the second bearing platform assembly can be driven to slide laterally and synchronously. Of course, more than one active load slider 3211 may be provided.

In order to form stable support for the article, the structure of the bearing surface of the second bearing slide block is similar to that of the bearing surface of the middle fixed bearing slide block, a second arc-shaped groove is formed in the bearing surface of the second bearing slide block, and a second supporting column is connected in the second arc-shaped groove. The second support columns are cylindrical and protrude out of the second arc-shaped grooves, so that the articles are supported by the plurality of second support columns arranged at intervals, and a multi-point stable support can be formed.

In this embodiment, the second conveying member 31 further includes two second conveying chains 311 arranged in parallel on the left and right, and the second conveying chains 311 are mounted on the sprockets and spread to form an annular structure with two ends in an arc shape and a straight middle part. The sprockets are mounted on second sprocket shafts 314, one of which is driven by a second conveyor motor 313, and in particular may be driven after passing through a speed reducer. Correspondingly, the second bearing platform assemblies and the second conveying rods move along the chain in a unidirectional circulating mode along an annular path together, the annular path comprises a straight moving path I, an arc moving path I, a straight moving path II and an arc moving path II, the straight moving path II is located on the opposite side of the straight moving path I, the straight moving path I and the straight moving path II are relatively parallel, and the arc moving path II is located on the opposite side of the arc moving path I. The straight motion path I, the arc motion path I, the straight motion path II and the arc motion path II are connected in sequence to form a closed annular motion path. Wherein, straight motion route I is located the upside, straight motion route II is located the downside, and arc motion route II and arc motion route I are located front side and rear side respectively.

The second conveying rod 312 may be configured as a hollow rod, and the second conveying rod rotates and is sleeved on a core rod, and two ends of the core rod are correspondingly connected with the links of the two chains.

As shown in fig. 19 to 22, the lane dividing component 33 includes a lane dividing rail 331 slidably connected to the lane dividing driving post 32111, the lane dividing rail 331 includes an inclined section 3311 inclined to the horizontal conveying path, and the lane dividing driving post 3211 is guided by the inclined section 3311 to move so as to drive the entire second loading platform assembly 321 to move laterally, so as to change the conveying path of the articles on the second loading platform assembly 321.

In the lane dividing process, a part of the second bearing platform assemblies 321 can keep not sliding laterally, and the other part of the second bearing platform assemblies 321 slide laterally to one side of the horizontal conveying path, so that the articles in one row can be divided into two rows. Of course, it is more preferable that a part of the second carriage platform assembly 321 slides laterally to one side of the horizontal conveying path, and another part of the second carriage platform assembly slides laterally to one side of the horizontal conveying path, so that a sufficient distance between two rows of articles after lane division can be maintained within a limited width. Accordingly, the lane dividing rail 331 is disposed on both left and right sides of the lane dividing component 33, that is, the lane dividing rail on the left side is matched with the lane dividing driving column 32111 of one part of the second supporting platform assemblies 321, and the lane dividing rail on the right side is matched with the lane dividing driving column 32111 of the other part of the second supporting platform assemblies 321.

In the lane dividing process, all the second bearing platform assemblies 321 continuously convey articles, so that the lane dividing process is continuously performed, and high-speed lane dividing can be realized.

Furthermore, the situation that the continuous high-speed lane dividing device 3 does not divide lanes needs to be considered, a straight track 332 is arranged in the middle of the lane dividing component, first ends of the lane dividing track 331 and the straight track 332 are connected with a first switching track 334, and the lane dividing track 331 and the straight track 332 are switched on and off through the first switching track 334. If a lane is not required, the first switch track 334 is switched on to the straight track 332 and the lane track 331 is switched off. If a lane is to be split, the first switch track 334 is connected to the split track 331 and the straight track 332 is disconnected. And, the first switching track 334 switches between the left hand lane rail and the right hand lane rail to determine whether the articles on the second load bearing platform assembly 321 will be diverted to the left hand side conveyor lane or the right hand side conveyor lane.

To achieve a fast and accurate switching of the first switch track 334, said first switch track 334 is rotatably connected to a pin and driven by a switch electric cylinder 335. Or may be driven by other drivers.

Further, in order to adjust the distance between two rows of articles after lane division, the lane dividing track 331 further includes at least two branch sections 3313 connected to the second end of the oblique section 3311. Taking two branch-off sections as an example, one branch-off section 3313 extends straight along the direction of the straight movement path i, corresponding to the distance between two rows of articles after relatively narrow lane division, and another branch-off section 331 is partially disposed in the extending direction of the inclined section 3311, and another branch-off section extends straight along the direction of the straight movement path i, corresponding to the distance between two rows of articles after relatively wide lane division. A second switch track 3312 is provided between the at least two branched sections 3313 and the second end of the inclined section 3311, and the opening and closing of the entrance of the branched section is realized by the second switch track 3312, that is, one branched section is connected and the other branched section is disconnected. If the second switch track 3312 is now connected to one of the branches 3313, corresponding to a relatively narrow spacing between the two rows of articles following the lane, and if a change is required to a relatively wide spacing between the two rows of articles following the lane, the second switch track 3312 is connected to the other branch 3313. When the lane driving post 32111 moves to the straight position of the forked section 3313, the second carriage assembly 321 moves laterally to the position after lane separation is completed, i.e., lane separation of two rows of articles is achieved.

To achieve a fast switching of the second switch rail 3312, the second switch rail 3312 is rotatably connected to a pin and driven by a switch cylinder 3314. Or may be driven by other actuators, such as electric cylinders.

When the second bearing platform assembly 321 passes through the straight moving path i, if the second bearing platform assembly 321 slides laterally to perform lane separation of the article, after the lane separation is completed, the second bearing platform assembly 321 still maintains the position after the lane separation. After the second supporting platform assembly 321 passes through the arc-shaped moving path i, the straight moving path ii, and the arc-shaped moving path ii in sequence, before entering the straight moving path i, the second supporting platform assembly 321 must return to the original position again to perform the shunting again. To achieve this, as shown in fig. 19 and 22, the lane member 33 is provided with a lane rail 331 and a straight rail 332 on the upper side and the lower side, respectively, and the positions and the extending directions of the upper side and the lower side are completely the same. Of course, it is understood that the first switch track 334 and the second switch track 3312 need not be provided on the underside, and that other configurations are consistent. Meanwhile, the front side and the rear side of the lane dividing component 33 are provided with second transition rails 333. The second transition track 333 is mounted on the second sprocket shaft 314. Wherein, the front side is provided with a second transition track, and the rear side is provided with a plurality of second transition tracks. The second transition track 333 has an arc-shaped section and straight sections connected to both ends of the arc-shaped section and parallel to each other, the straight section on the front side is connected to the first switching track, and the straight section on the rear side is connected to the diverging section and the straight track. Thus, if the second bearing platform assembly slides laterally when passing through the straight motion path I, the second bearing platform assembly returns again after passing through the straight motion path II. Thus, the operation is repeated.

While the foregoing is directed to embodiments of the present invention, the scope of the invention should not be limited thereby, and it will be apparent to those skilled in the art that the invention includes, but is not limited to, those illustrated in the drawings and described in the foregoing detailed description. Any modification which does not depart from the functional and structural principles of the invention is intended to be included within the scope of the claims.
