在分配器和系统中的保持机构包括保持机构和端塞

Retention mechanism in a dispenser and system comprising a retention mechanism and an end plug
Abstract:
A retention mechanism (40) for a dispenser for retaining an end plug (10) of an exchangeable roll of material includes an insertion slot extending between a receiving end (54) and a seating region (50) for inserting a bearing pin (22) of the end plug. The bearing pin has at least a first portion (26) with a first diameter, and a second portion (28) with a second diameter smaller than the first diameter. A pin discriminator (46) is at least at the receiving end and narrows the receiving end so only bearing pins can enter the receiving slot which have a maximum outer diameter in the second portion which equals the second diameter. A rejecting slot (48) extends from the seating region and is dimensioned so only bearing pins with a predetermined maximum diameter in the first portion which is smaller than the first diameter will enter the rejecting slot.
Abstract(Chinese):

用于保持可更换材料卷的端塞（10）的分配器的保持机构（40）包括在接收端（54）和用于插入轴承销（22）的就位区域（50）之间延伸的插槽， 的端塞。 轴承销至少具有第一直径的第一部分（26）和具有小于第一直径的第二直径的第二部分（28）。 针鉴别器（46）至少在接收端并且使接收端变窄，因此只有轴承销可以进入在第二部分中具有等于第二直径的最大外径的接收槽。 拒绝槽（48）从座位区域延伸并且尺寸使得仅在小于第一直径的第一部分中具有预定最大直径的轴承销将进入拒收槽。
