Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Fig. 1-4 illustrate a roller conveyor according to a preferred embodiment of the present invention. It comprises a frame 1 and a plurality of groups of conveying components 2 arranged on the frame 1. Referring to fig. 5 and 6, the conveying assembly 2 includes a motor driving assembly 21, a plurality of conveying rollers 221, and a lateral guide limit plate 23. The motor drive assembly 21 is in driving connection with the conveyor roller 221, and it is understood that it may be in direct driving connection or may be in driving connection through an intermediate transmission structure. The plurality of conveying rollers 221 are sequentially arranged in parallel and at intervals along the conveying direction of the roller type conveying device, and the lateral guide limiting plate 23 extends along the conveying direction of the roller type conveying device and is positioned at one end of the conveying rollers 221. Importantly, the horizontal height of the end of the conveying roller 221 near the lateral guiding limiting plate 23 is lower than the horizontal height of the end of the conveying roller 221 far away from the lateral guiding limiting plate 23, so that the product supported by the conveying roller 221 can slide downwards under the action of self gravity until the product is abutted against the lateral guiding limiting plate 23. And, importantly, the multiple sets of conveying assemblies 2 are disposed at intervals in the horizontal direction.

When the packaging machine works, a plurality of groups of conveying assemblies 2 of the packaging machine simultaneously receive products and convey the products on the conveying assemblies 2 in parallel, and a motor driving assembly 21 drives part of adjacent conveying rollers 221 to generate a speed difference, so that products positioned below in the overlapped products are suddenly accelerated, and the speed of the products positioned above is kept unchanged due to inertia, so that the overlapped products generate relative displacement; the overlapped products may be separated after they have undergone multiple relative displacements on the conveyor assembly 2. And, based on that the horizontal height of one end of the conveying roller 221 near the lateral guiding limiting plate 23 is lower than the horizontal height of one end of the conveying roller 221 far away from the lateral guiding limiting plate 23, the product supported by the conveying roller 221 can slide down under the action of self gravity until the product is abutted against the lateral guiding limiting plate 23, so that the product sent out from the conveying assembly 2 falls on the blanking conveying belt of the packaging mechanical equipment in a regular and uniform manner and is sequentially sent out. In addition, based on multiunit conveying component 2 along the horizontal direction interval setting to roller conveyor's conveying efficiency has been improved, and based on the blanking point of each multiunit conveying component 2 all laminating respective side direction limiting plate 23, thereby make the blanking between two adjacent conveying components 2 overlap, in order to avoid causing the phenomenon that the product appears overlapping again.

Preferably, referring to fig. 5, multiple sets of conveyor assemblies 2 are disposed at intervals and in an array along the horizontal direction. By the arrangement, the horizontal spacing between two adjacent lateral guide limiting plates 23 is further different, so that the phenomenon of overlapping of products is further avoided. That is, the two adjacent conveying assemblies 2 may be arranged in mirror image, but the horizontal spacing between the two adjacent lateral guiding limiting plates 23 is relatively close.

Preferably, referring to fig. 5, in order to intercept the overlapped products more surely for subsequent packing of the products, the lateral guide limiting plate 23 is provided with a height limiting block 24, the height limiting block 24 is disposed right above the conveying roller 221, and the height limiting block 24 is used for separating the overlapped products.

Preferably, referring to fig. 8-11, the transport roller 221 includes an inner roller 2211 and an outer roller 2212, the inner roller 2211 and the outer roller 2212 being pivotally connected to each other and coaxially arranged (fig. 9 shows that the inner roller 2211 and the outer roller 2212 are pivotally connected to each other outside the stationary support bar 2213 by respective bearing sets). Referring to fig. 5-7, the motor drive assembly 21 is comprised of a plurality of unit motor sets, each unit motor set being drivingly connected to one or more conveyor rollers 221. The unit motor group includes a first motor 211 and a second motor, the first motor 211 is in driving connection with the inner roller 2211, and the second motor is in driving connection with the outer roller 2212. In the present roller conveyor, the second motor and the first motor 211 are staggered in the horizontal direction. So configured, the speed of the inner roller 2211 is controlled by the first motor 211 and the speed of the outer roller 2212 is controlled by the second motor, so that when the product is between the inner roller 2211 and the outer roller 2212, a differential roller is formed based on the difference between the speed of the inner roller 2211 and the speed of the outer roller 2212, so that the product is turned, and the orientations of all the products are the same, thereby facilitating the automatic packing of the product. It should be specifically noted that, the product is generally rectangular, that is, the sides thereof have long sides and short sides, and when the product is attached to the lateral guiding limiting plate 23: if the long side is different from the self-conveying direction, the long side is inevitably interposed between the inner side roller 2211 and the outer side roller 2212, and thus the direction of rotation occurs, and if the long side is the same as the self-conveying direction, the long side length is smaller than the length of the inner side roller 2211, and thus the long side is no longer located between the inner side roller 2211 and the outer side roller 2212, and the product is oriented as a target. It should be noted that, at this time, the differential speed between the adjacent conveying rollers 221, that is, the differential speed between the adjacent two unit motor groups, that is, the speeds of the conveying rollers 221 belonging to the same unit motor group are the same, and the speeds of the two conveying rollers 221 adjacent to and belonging to different unit motor groups are different.

Preferably, referring to fig. 5 to 7, each unit motor group is drivingly connected to a plurality of conveying rollers 221, and a plurality of conveying rollers 221 drivingly connected by the same unit motor group are defined as a combination roller 22.

The outer roll 2212 has a second pulley surface 22121, and a plurality of second pulley surfaces 22121 belonging to the same set of combination rolls 22 are wound by a second belt. The first pulley surface 22111 and the second pulley surface 22121 may be located at the same end of the conveying roller 221, or may be located at both ends of the conveying roller 221, respectively.

In the present invention, it is preferable that: some or all of the adjacent two conveying rollers 221 in the combination roller 22 are in winding connection through the first driving belt 25, and taking fig. 7 as an example, the combination roller 22 consists of six conveying rollers 221, and the combination roller 22 is in winding connection with four first driving belts 25. It will be appreciated that the second belts are equal in number to the first belts 25 and are disposed at the same end of the conveyor roller 221.

Preferably, referring to fig. 7, in order to make the installation positions of the first motor 211 and the second motor more reasonable, the first motor 211 of the unit motor group is wound with at least one of the first pulley surfaces 22111 through the third transmission belt 26; the second motor of the unit motor group is wound with at least one of the second pulley surfaces 22121 through a fourth transmission belt. In fig. 7, it can be clearly seen that the third belt 26 is wound around the two first belt surfaces 22111.

Preferably, the length of the inner roll 2211 is different from the length of the outer roll 2212 such that one of the two is a short roll and the other is a long roll. Obviously, the length between the two can be the same.

Preferably, in order to further improve the conveying efficiency of the present roller conveyor, the partial conveying assemblies 2 are arranged at intervals in the direction of gravity. In this case, the conveying directions of the two conveying assemblies 2 arranged one above the other are preferably opposite to avoid overlapping of the products at the discharge points of the two.

Preferably, referring to fig. 7, the outer curved surface wall of the conveying roller 221 is provided with a plurality of stripe-shaped anti-slip stripes 222, and the plurality of anti-slip stripes 222 are disposed at intervals around the circumferential direction of the conveying roller 221.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
