Conveying mechanism follows in this application the length of first direction is adjustable, can effectively improve the matching nature of conveyer and different carriages or cupboard to improve discharge efficiency.

Referring to fig. 1 and 2, the conveying device 10 includes a conveying mechanism 100, a telescopic assembly 200, a baffle assembly, and a first driving mechanism. The conveying mechanism 100 includes a first conveying group 110 and a second conveying group 120, and the second conveying group 120 is disposed on at least one side of the first conveying group 110. The first transfer group 110 includes at least one transfer assembly, and the second transfer group 120 includes at least one transfer assembly, a plurality of which are arranged side by side along the first direction F1. It should be noted that the conveying assembly may be a belt conveyor or a roller line, and the plurality of conveying assemblies may be the same or different.

In some embodiments of the present application, the first transfer group 110 is provided with the second transfer group 120 on both sides thereof. The telescopic assembly 200 drives the second conveying groups 120 at both sides to move along the telescopic direction of the telescopic assembly 200 during the telescopic process, and the telescopic direction of the telescopic assembly 200 is the same as the first direction F1. In one possible way, the telescopic assembly 200 is fixedly connected to the two second conveying groups 120, so as to drive the two second conveying groups 120 to move towards or away from the first conveying group 110 at the same time. Of course, the telescopic assembly 200 may be fixedly connected to the second transmission group 120 and the first transmission group 110 on both sides, respectively, so as to drive the second transmission group 120 and the first transmission group 110 on both sides to move toward or away from each other. It should be noted that in other embodiments of the present invention, the telescoping direction of the telescoping assembly 200 may be different from the first direction F1, for example, the included angle (acute angle) between the telescoping direction and the first direction F1 is 0 ° to 45 °.

It is understood that the second conveying groups 120 are disposed on both sides of the first conveying group 110, and the second conveying groups 120 on both sides can move toward or away from the first conveying group 110, so that the length adjustment of the conveying mechanism 100 in the first direction F1 is more flexible and has a larger adjustment range. It is further preferred that the 2 second conveying groups 120 are symmetrically distributed on both sides of the first conveying group 110, which facilitates the adjustment and control of the length of the conveying mechanism 100 in the first direction F1.

In some embodiments of the present application, the second conveying group 120 includes a plurality of conveying assemblies arranged side by side, and the plurality of conveying assemblies may be the same or different. Specifically, the conveying assembly is a belt conveyor. The second conveying group 120 includes a first belt conveyor 121, a second belt conveyor 122, and a third belt conveyor 123 arranged in parallel. The first belt conveyor 121, the second belt conveyor 122 and the third belt conveyor 123 are respectively and fixedly connected with the telescopic assembly 200. One possible way is that the telescopic assembly 200 drives the first belt conveyor 121, the second belt conveyor 122, and the third belt conveyor 123 to move toward or away from the first conveying group 110 at the same time. It should be noted that the conveying surfaces of the first belt conveyor 121, the second belt conveyor 122, the third belt conveyor 123, and the first conveying group 110 are located on the same horizontal plane, where the conveying surface refers to a surface of the conveyor belt that carries and conveys goods, that is, an upper plane of the conveyor belt. In other embodiments of the present invention, the conveying assemblies may also be roller lines, such as edge roller lines, since the edge roller lines can change the conveying direction of the goods thereon, the goods on the edge roller lines can be conveyed to the adjacent conveying assemblies, and one or more conveying assemblies in the second conveying group 120 are set to be edge roller lines, which facilitates the goods on the second conveying group 120 to converge onto the first conveying group 110, so as to effectively prevent the goods on the second conveying group 120 from stacking or jamming when converging onto the first conveying group 110 through the first baffle assembly 510, thereby enabling the conveying mechanism 100 to have higher conveying efficiency.

In some embodiments of the present application, the first belt conveyor 121 includes a pair of rollers 1211 disposed opposite to each other in a conveying direction, a first belt 1212 wound around the pair of rollers 1211, a first belt support plate (not shown), and a roller mounting bracket (not shown). The roller mount comprises a pair of first side plates 1213 oppositely arranged along the first direction F1. The pair of rollers 1211 is disposed between the pair of first side plates 1213, and is rotatably connected to the pair of first side plates 1213. The first belt supporting plate is fixed on one first side plate 1213 and is abutted to the upper belt segment in the first belt 1212, so that the bearing weight of the first belt conveyor 121 can be effectively improved. The second belt conveyor 122 and the third belt conveyor 123 may have the same or similar structure as the first belt conveyor 121, and will not be described again.

In some embodiments of the present application, the baffle assembly includes a first baffle assembly 510. The first baffle assembly 510 is used for guiding the goods on the second conveying group 120 to move towards the first conveying group 110. Specifically, the baffle assembly comprises 2 first baffle assemblies 510, and the 2 first baffle assemblies 510 are symmetrically arranged on two sides of the conveying mechanism 10. 2 of the first baffle assemblies 510 enclose the conveyor mechanism 100 to form a cargo conveyor line. In the conveying direction of the conveying mechanism 100, the first flap assembly 510 has a first end 501 and a second end 502. The first end 501 extends to the outside of the first belt conveyor 121 (the side away from the first conveying group 110), and the second end 502 extends to the first conveying group 110. The distance between the 2 first end portions 501 is greater than the distance between the 2 second end portions 502, the goods enter the conveying mechanism 100 through the gap between the 2 first end portions 501, and the goods on the second conveying group 120 are conveyed to the first conveying group 110 under the limiting and guiding effects of the corresponding first baffle plate assemblies 510.

Preferably, the first baffle assembly 510 includes a plurality of first sub-baffles 511, and the plurality of first sub-baffles 511 are distributed in a splayed shape at both sides of the first conveying group 110. Specifically, the first baffle assembly 510 further includes a first side baffle 512, each of the conveying assemblies is provided with a corresponding first sub-baffle 511, an included angle (acute angle) between the extending direction of the first sub-baffle 511 and the conveying direction is 30 ° to 60 °, and the plurality of first sub-baffles 511 are arranged in parallel. The first side baffle 512 is fixed on the first side plate 1213 and extends along the conveying direction of the first belt conveyor 121. One end (namely, the first end 501) of the first sub-baffle 511 on the first belt conveyor 121 is fixedly connected with the first side baffle 512, and the other end extends to the inner side (close to the side of the first conveying group 110) of the first sub-baffle 511 on the second belt conveyor 122, so that the two adjacent first sub-baffles 511 are effectively prevented from interfering when the two adjacent belt conveyors are close to or away from each other, and the clamping of the two adjacent first sub-baffles 511 at the joint of the first sub-baffles 511 can be effectively prevented when the goods on the first belt conveyor 121 are conveyed to the second belt conveyor 122. Of course, in other embodiments of the present application, the first side flap 512, the first side plate 1213 fixedly connected to the first side flap 512, and the first sub-flap 511 on the first belt conveyor 121 may also be an integrally formed structure, so that the assembly of the conveying apparatus 10 is more convenient.

It can be understood that when the first driving mechanism drives the first belt conveyor 121 to move along the first direction F1 toward the direction approaching the second belt conveyor 122, the overlapping portions of the two first baffle plates 511 on the first belt conveyor 121 and the second belt conveyor 122 respectively gradually increase as the first belt conveyor 121 moves along the first direction F1 toward the direction approaching the second belt conveyor 122, that is, the projected area of the first baffle plates 511 on the first belt conveyor 121 on the first baffle plates 511 on the second belt conveyor 122 gradually increases; similarly, when the first driving mechanism drives the first belt conveyor 121 to move in the first direction F1 toward the direction away from the second belt conveyor 122, the overlapping portions of the two first baffle plates 511 respectively located on the first belt conveyor 121 and the second belt conveyor 122 gradually decrease to compensate for the increased distance between the belt conveyors, so that the structure of the conveying device 10 is more compact and has better applicability.

It can be understood that the extension of the other side of the first sub-barrier 511 on the second belt conveyor 122 to the inner side (the side close to the first conveying group 110) of the first sub-barrier 511 on the third belt conveyor 123 can effectively prevent the occurrence of the jamming at the joint of two adjacent first sub-barriers 511 when the goods on the second belt conveyor 122 are conveyed to the third belt conveyor 123. The first sub-baffles 511 on the other belt conveyors have the same or similar structural arrangement and will not be repeated herein.

In some embodiments of the present application, the baffle assembly further comprises a second baffle assembly 520, and the second baffle assembly 520 is used for preventing goods from falling off from a gap between two adjacent belt conveyors.

It can be understood that, in the embodiment of the present application, when the driving mechanism 310 drives the plurality of conveying assemblies to approach each other, the gap between two adjacent conveying assemblies is reduced, and the length of the conveying mechanism 100 along the first direction F1 becomes smaller; when the driving mechanism 310 drives the plurality of conveyance assemblies to approach each other, the gap between adjacent two conveyance assemblies increases, and the length of the conveyance mechanism 100 in the first direction F1 becomes larger. It can be understood that when the first driving mechanism drives the plurality of conveyor assemblies to move away from each other along the first direction F1, the gap between two adjacent conveyor belts is inevitably increased, which easily causes the goods to fall off from the gap between two adjacent conveyor belts, and therefore it is necessary to provide the second baffle assembly 520 in the conveyor 10 to prevent the goods from falling off from the gap between two adjacent conveyor belts.

Preferably, the second baffle assembly 520 comprises a plurality of second baffles 521, and the plurality of second baffles 521 are respectively arranged on a plurality of belt conveyors; when the plurality of belt conveyors approach the first conveying group 110 along the first direction F1, the second baffle 521 may be accommodated below the adjacent belt conveyors.

Specifically, a second baffle 521 is arranged on a first side plate 1213 of the first belt conveyor 121, which is close to the second belt conveyor 122, and the second baffle 521 extends towards the second belt conveyor 122 to the inside of the second conveyor belt 1221. One possible implementation is that the top of the second side plate 1222 is located below the upper belt of the second conveyor belt 1221, and it is understood that a receiving space (not shown) is formed between the upper belt and the lower belt of the second conveyor belt 1221, and the second baffle 521 can pass through a gap between the corresponding second side plate 1222 and the upper belt of the second conveyor belt 1221 and enter the receiving space, and is disposed close to the upper belt of the second conveyor belt 1221. When the first driving mechanism drives the first belt conveyor 121 and the second belt conveyor 122 to approach each other, the second baffle 521 moves towards the direction of approaching the second belt conveyor 122 along the first direction F1, and is gradually accommodated in the accommodating space enclosed by the second conveyor belt 1221; when the first driving mechanism drives the first belt conveyor 121 and the second belt conveyor 122 to be away from each other, the gap between the first belt conveyor 121 and the second belt conveyor 122 is gradually increased, and the second baffle 521 is gradually moved out of the accommodating space formed by the enclosing of the second conveyor belt 1221, so that the goods are prevented from falling off from the gap between the first belt conveyor 121 and the second belt conveyor 122, the structure of the conveying device 10 is more compact, and the conveying device has better applicability. The second apron 521 of the second belt conveyor 122 and the third belt conveyor 123 may have the same or similar structure as the second apron 521 of the first belt conveyor 121, and will not be described again.

In some embodiments of the present application, the first conveying group 110 comprises a first conveying segment 111 and a second conveying segment arranged in the conveying direction. The first conveying section 111 comprises a plurality of belt conveyors arranged side by side, the second conveying section is respectively abutted to the plurality of belt conveyors in the first conveying section 111, and the plurality of belt conveyors in the first conveying section 111 are respectively provided with independent second driving mechanisms (not marked in the figure).

Specifically, the first conveying section 111 includes a fourth belt conveyor 1111, a fifth belt conveyor 1112, and a sixth belt conveyor 1113. The second transfer section comprises a seventh belt conveyor 112. The fourth belt conveyer 1111, the fifth belt conveyer 1112 and the sixth belt conveyer 1113 are arranged side by side, and the seventh belt conveyer 112 is abutted against the fourth belt conveyer 1111, the fifth belt conveyer 1112 and the sixth belt conveyer 1113 respectively, that is, the cargo on the fourth belt conveyer 1111 or the fifth belt conveyer 1112 or the sixth belt conveyer 1113 can be conveyed to the seventh belt conveyer 112. The fourth belt conveyor 1111, the fifth belt conveyor 1112 and the sixth belt conveyor 1113 are respectively provided with an independent second driving mechanism, that is, the rotating speeds of the fourth belt conveyor 1111, the fifth belt conveyor 1112 and the sixth belt conveyor 1113 can be freely set. It can be understood that the cargo on the second conveying group 120 needs to be converged onto the first conveying assembly 110, which easily causes the cargo on the conveying mechanism 100 to be jammed at the junction (i.e. the position between the two oppositely disposed 2 second ends 502). The fourth belt conveyor 1111, the fifth belt conveyor 1112 and the sixth belt conveyor 1113 are respectively provided with an independent second driving mechanism which can flexibly control the rotating speed of the fourth belt conveyor 1111, the fifth belt conveyor 1112 and the sixth belt conveyor 1113, and can effectively prevent the clamping of goods at the junction. Of course, in other embodiments of the present invention, the first conveying group 110 may also include only one belt conveyor, which is not limited herein.

Referring to fig. 2, in some embodiments of the present application, the transfer device 10 further includes a guide assembly 400. Specifically, the guide assembly 400 includes 2 guide shafts 410 disposed along the conveying direction, and a plurality of linear bearings 420 coupled to the guide shafts 410. The guide shaft 410 extends in the first direction F1. Through holes (not marked in the figure) are formed in the first side plate 1213, the second side plate 1222 and the third side plate 1231, each through hole is provided with a corresponding linear bearing 420, and the linear bearings 420 are arranged on the inner sides of the corresponding conveyor belts and fixed on the corresponding belt conveyor mounting side plates, so that the maintenance cost of the linear bearings 420 can be reduced, and the structure of the conveyor 10 is more compact. The outer end of the guide shaft 410 (i.e., the end away from the first conveying set 110) is fixedly connected to the first side plate 1213, the inner end of the guide shaft 410 (i.e., the other end of the guide 410) sequentially passes through the plurality of through holes and the linear bearing 420 and extends to the inner side of the conveying belt of the fifth belt conveyor 1112, and the guide shaft 410 is slidably connected to the linear bearing 420. It can be understood that, since the guide shaft 410 is slidably connected with the linear bearing 420, the second belt conveyor 122 and the third belt conveyor 123 can slide along the guide shaft 410. The outer end of the guide shaft 410 is fixedly connected to the first belt conveyor 121, and when the first driving mechanism works, the first belt conveyor 121, the guide shaft 410, the second belt conveyor 122, and the third belt conveyor 123 move in a direction approaching or departing from the first conveying group 110 along the first direction F1 under the driving action of the telescopic assembly 200.

In some embodiments of the present application, the retraction assembly 200 is a scissor-set retraction assembly. The telescopic assembly 200 includes a plurality of scissor sets 210 arranged along the first direction F1, each scissor set 210 includes a first fork 211 and a second fork 212 hinged to each other in a crossing manner, two adjacent scissor sets 210 are hinged to each other, and a hinge shaft 213 of each scissor set 210 is fixedly connected to a corresponding belt conveyor. Each scissor group 210 is arranged on the inner side of the corresponding conveyor belt, so that the interference of the external environment can be effectively avoided, the potential safety hazard can be reduced as much as possible, and the structure of the conveyor device 10 is more compact. It will be appreciated that the 2 scissor sets 210 at the ends of the telescoping assembly 200 have one end with a hinge shaft 213 and the other end with an adjacent scissor set. The two ends of the scissor set 210 located in the middle of the telescopic assembly 200 are hinged to the adjacent scissor sets respectively. Of course, in other embodiments of the present invention, the telescopic assembly 200 may also be a sliding telescopic assembly, such as a telescopic plate or a telescopic rod, and the plurality of belt conveyors are fixedly connected to a plurality of telescopic units of the telescopic plate or the telescopic rod, respectively.

Specifically, the telescoping assembly 200 includes 4 scissor sets 210. A hinge base 113 is provided on the first side plate 1213 located at the outer side, and a hinge shaft 213 of 1 scissor group 210 (i.e. one scissor group away from the first conveying group 110) corresponding to the first belt conveyor 121 is fixed to the corresponding hinge base 113. A limiting hole 124 is respectively formed in the other first side plate 1213 and the adjacent second side plate 1222, and one end of the 1 scissor set 210 corresponding to the second belt conveyor 122 (i.e. one end of the first fork 211 and the second fork 212) extends to the inner side of the first belt conveyor 1212 through the limiting hole 124, and is hinged to the first fork 211 and the second fork 212 in the 1 scissor set corresponding to the first belt conveyor 121. The other scissor sets 210 have the same or similar structure and will not be repeated here.
