    • A roller conveyor drive chain is equipped with drive transmission elements (30) for frictionally contacting the rollers (12) of the conveyor (10). Each element (30) is secured to a respective link of the chain (15) and extends at each end beyond this link to overlap the adjacent chain link. The parts of the elements (30) which project beyond their own chain link are an assymetrical wedge shape, having one side extending at an acute angle to the length of the chain (15) so that two adjacent elements (30) overlap one another laterally and have a line of separation which is acutely inclined across the chain (15) to reduce transmission noise as the elements (30) pass in contact with the rollers (12).
    • 辊式输送机驱动链装备有用于摩擦地接触输送机(10)的辊(12)的传动传动元件(30)。 每个元件(30)被固定到链条(15)的相应链节上,并且在每个端部延伸超出该链接以与相邻链节重叠。 突出超过其自身链节的元件(30)的部分是不对称的楔形,其一侧以与链条(15)的长度成锐角延伸,使得两个相邻的元件(30)横向彼此重叠 并且具有横跨链条(15)急剧倾斜的分离线,以在元件(30)通过与辊(12)接触时减小传动噪声。

    • The conveyor has a plurality of conveyor rollers (81) forming an article-conveying surface, a powered primary belt (84) for driving the rollers from beneath for moving articles downstream opposite to the direction of movement of the belt, a plurality of support units (20a, 20b) supporting the primary belt from beneath, each of the units having inner and outer wheels each having a flattened peripheral rest area (70), lost motion connections between the inner and outer wheels permitting the flattened surfaces of all the wheels to be aligned or misaligned whereby the wheels, when misaligned, collectively form a circular primary belt-supporting surface, the support units (20a, 20b) being arranged in groups along the conveyor, an endless sensing belt (80) being connected to the last upstream support unit (20b) of each group and extending downstream therefrom in fixed driven contact with some of the conveyor rollers (81) above the group to sense movement of the conveyor rollers (81); endless belts (83) interconnecting for simultaneous rotation the inner wheels of all but the last upstream one of the support units (20a, 20b) of each group with the last upstream drive unit of the next downstream group; the flattened surfaces (70) of all connected inner wheels being identically positioned; the lost motion connections permitting the inner and outer wheels to assume misaligned, circular belt-supporting relationship, and when the sensing belt (80) is braked by the conveyor rollers (81) the inner and outer wheels will be caused to assume an in-phase relationship permitting the belt (84) to drop into accumulation position.
    • 输送机具有形成物品输送表面的多个输送辊[81],用于从下方驱动辊的动力主带[84],用于在与带的运动方向相反的下游移动物品,多个支撑单元 [20a,20b]从下面支撑主带,每个单元具有内轮和外轮,每个具有扁平的周边休止区域[70],内轮和外轮之间的运动连接不足,允许所有车轮的平坦表面 对准或不对准,由此当未对准的车轮共同形成圆形的初级带支撑表面时,支撑单元[20a,20b]沿输送机组成一组,环形传感带[80]连接到最后的上游 每个组的支撑单元[20b]并且在组的下方的一些输送辊(81)固定的驱动接触中从其下游延伸,以感测输送辊[81]的运动。 互连用于同时旋转每组的最后上游一个支撑单元[20a,20b]的内轮与下一个下游组的最后一个上游驱动单元的环形带[83] 所有连接的内轮的平坦表面[70]相同地定位; 允许内轮和外轮呈现不对准的圆形带支撑关系的迷失运动连接,并且当传感带[80]被输送辊[81]制动时,将使内轮和外轮呈现在内侧, 相位关系允许皮带[84]下降到累积位置。
