    • Either a focused beam (22) or a spatial (42) movable scanning unit which is attached to a movable horizontal arm (27) which is attached to a stand (26) such that the scanning unit can be controllably directed throughout a prescribed vertical-horizontal plane which is parallel to one end of a unit of lumber (10). Separate stands (26) are placed at either end of the unit (10). Throughout the automatic directed movement, the scanning unit either emits focused beam (38) and/or receives reflected energy beams (38 and 48) which have reflected off the end of unit (10). These reflected beams are in accordance with the surface pattern of unit (10) and are input to a topological processor (22b or 42b) which translates this information into the geometric attributes ot thickness, width and length. The exact count of distinct pieces of lumber of distinct geometric attributes is then transmitted to computer (28) as the unit's end tally. The computer (28) may accept related information through input means of a keypad (33) or bar code reader (34). The unit's end tally and related information may be transmitted via a bi-directional communications link (36) to a companion computer system which may in return transmit an associated identification number to be assigned to unit (10). Any or all of this determined and collected information may also be transmitted via link (36) to an automatic tagging sub-system (60). This sub-system is capable of printing tag (11) which is taken by grasping and stapling hand (72) which is further attached to movable arm (70) such that sub-system (60) may then automatically staple tag (11) to unit (10).
    • 聚焦光束(22)或空间(42)可移动扫描单元连接到可移动的水平臂(27)上,该可移动的水平臂连接到支架(26)上,使得扫描单元可以可控制地指向整个预定的竖直方向, 与木材单元(10)的一端平行的水平面。 独立支架(26)放置在单元(10)的任一端。 在整个自动定向运动中,扫描单元发射聚焦光束(38)和/或接收反射离开单元(10)末端的反射能量束(38和48)。 这些反射光束与单元(10)的表面图案相一致并被输入到拓扑处理器(22b或42b),该处理器将该信息转换成厚度,宽度和长度的几何属性。 然后将计数器(28)作为单元的最终计数器传送给不同几何属性的不同部分的准确计数。 计算机(28)可以通过小键盘(33)或条形码阅读器(34)的输入装置接受相关信息。 该单元的最终计数和相关信息可以通过双向通信链路(36)传送到伴随计算机系统,该伴随计算机系统可以反过来发送要分配给单元(10)的相关联的识别号码。 这些确定和收集的信息中的任何一个或全部也可以通过链路(36)传输到自动标签子系统(60)。 该子系统能够打印标签11,该标签11通过抓握和钉合手72进一步附接到可移动臂70,使得子系统60然后可以自动地将标签11固定到 单元(10)。
