As used herein, the term "and/or" 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. The device comprises a machine frame 1 and a plurality of groups of conveying assemblies 2 arranged on the machine frame 1. Referring to fig. 5 and 6, the conveyor assembly 2 includes a motor drive assembly 21, a plurality of conveyor rollers 221, and a lateral guide limit plate 23. The motor driving assembly 21 is drivingly connected to the feeding roller 221, and it is understood that the motor driving assembly may be directly drivingly connected or may be drivingly connected through an intermediate transmission structure. A plurality of feed rollers 221 are arranged in parallel and at intervals in order along the feed direction of a roller type feed device, and the lateral guide restriction plate 23 extends along the feed direction of a roller type feed device and is located at one end of the feed rollers 221. Importantly, the horizontal height of the end of the conveying roller 221 close to the lateral guide limiting plate 23 is lower than the horizontal height of the end of the conveying roller 221 far from the lateral guide limiting plate 23, so that the product supported by the conveying roller 221 can slide down under the action of self gravity until the product is close to the lateral guide limiting plate 23. And, importantly, the sets of conveyor assemblies 2 are arranged at intervals in the direction of gravity, and the plurality of lateral guide limit plates 23 are arranged at intervals in the horizontal direction. In this way, the plurality of sets of conveyor assemblies 2 arranged at intervals in the direction of gravity are arranged in a staggered manner in the horizontal direction, that is, the lateral guide limit plates 23 arranged at intervals in the direction of gravity are arranged in a staggered manner.

When the packaging machinery equipment works, a plurality of groups of conveying assemblies 2 of the packaging machinery equipment receive products at the same time, namely the products are conveyed on the conveying assemblies 2 at different horizontal heights, and a speed difference is generated between part of adjacent conveying rollers 221 driven by the motor driving assembly 21, so that the products positioned below in the overlapped products are accelerated suddenly, and the speed of the products positioned above is kept unchanged due to inertia, so that the overlapped products generate relative displacement; the overlapping products can be separated out after they have undergone a plurality of relative displacements on the conveyor assembly 2. And based on the fact that the horizontal height of the end, close to the lateral guide limiting plate 23, of the conveying roller 221 is lower than the horizontal height of the end, far away from the lateral guide limiting plate 23, of the conveying roller 221, the product supported by the conveying roller 221 can slide downwards under the action of self gravity until the product laterally abuts against the lateral guide limiting plate 23, so that the product sent out from the conveying assembly 2 can fall on a blanking conveying belt of packaging machinery equipment in a neat and neat manner and can be sent out in sequence. In addition, the plurality of groups of conveying assemblies 2 are arranged at intervals along the gravity direction, so that the conveying efficiency of the roller type conveying device is improved, and the occupied area is not required to be greatly increased. Moreover, the plurality of lateral guiding limit plates 23 are arranged at intervals along the horizontal direction, so that the blanking among the plurality of conveying assemblies 2 arranged at intervals along the gravity direction is not overlapped, and the phenomenon that the products are overlapped again is avoided.

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

Preferably, referring to fig. 8-11, the delivery 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 (see fig. 9: the inner roller 2211 and the outer roller 2212 are pivotally connected to the stationary support bar 2213 by respective sets of bearings). Referring to fig. 5-7, the motor driving assembly 21 is composed of a plurality of unit motor sets, each unit motor set being drivingly connected to one or more of the feed rollers 221. The unit motor group comprises a first motor 211 and a second motor, wherein the first motor 211 is in driving connection with the inner side roller 2211, and the second motor is in driving connection with the outer side roller 2212. In the present roller type conveying apparatus, the second motor is arranged to be staggered in the horizontal direction with respect to the first motor 211. So arranged, the speed of the inside roller 2211 is controlled by the first motor 211 and the speed of the outside roller 2212 is controlled by the second motor, so that when a product is between the inside roller 2211 and the outside roller 2212, a differential roller is formed based on the difference between the speed of the inside roller 2211 and the speed of the outside roller 2212, so that the product is diverted, and thus all the products are oriented in the same direction, which is more beneficial to the automatic packaging of the product. It needs to be specified to say that, the product generally is the rectangle structure, and its length of side has long limit and minor face promptly, after product laminating side direction limiting plate 23: if the long side is different from the self-conveying direction, it is inevitably interposed between the inner roller 2211 and the outer roller 2212, and thus the turning occurs, and if the long side is the same as the self-conveying direction, it is no longer positioned between the inner roller 2211 and the outer roller 2212 because the length of the short side is smaller than that of the inner roller 2211, and the product is oriented in the target direction. It should be noted that, at this time, the differential speed between adjacent conveying rollers 221, that is, the differential speed between two adjacent unit motor sets, that is, the speeds of the conveying rollers 221 belonging to the same unit motor set are the same, and the speeds of two conveying rollers 221 belonging to different unit motor sets are different.

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 by the third belt 26; the second motor of the unit motor set is wound around 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 trained around two first belt wheel surfaces 22111.

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