摘要： A tool-changing system for a press utilizes a rotary turret on which different tools are rigidly fixed. The turret includes a circular table base which is rotatably mounted on top of the press anvil. As the turret is turned, a different tool is moved into the work zone in vertical alignment with the upper tool on the press ram. The turret table can either be manually or motor driven in either direction between indexed operative positions. The indexing system which senses the position of the turret and indexes the turret to its next operating position uses only two simple sensors which are located beneath the turret table. Each sensor reads a different circular track on the underside of the turret table.

摘要： A light-controlled safety switch for an automated press includes an optical transmitter and receiver affixed to the press frame just above the press ram that redirects the light beam from vertical to horizontal. A light beam is directed downward from the transmitter to a 45-degree reflective surface on the ram. A cross-hole, perpendicular to the centerline of the ram, and a second 45-degree opposite-facing reflector opposite to the first reflective surface returns the light beam to the receiver. Thus, an optical path is achieved from the transmitter to the first reflector, through the ram, to the second reflector and then back up to the receiver. The opposing 45-degree reflectors are preferably provided by a 45-degree dished collar with a light-reflective interfacing surface fitted about the ram. The collar, and thus the reflective surfaces, stroke up and down with the movement of the ram, but maintains the optical path from the transmitter to the receiver because the send and receive light paths are parallel to the linear motion of the ram. A light-blocking shutter is connected to the top of a slidable punch holder assembly that breaks the horizontal light beam through the ram centerline whenever the punch contacts an object. Thus, the present optical system replaces the hard-wired punch contact safety switch of the prior art and its external wiring, thereby providing many advantages.
摘要翻译： 用于自动压力机的光控安全开关包括固定到压机框架上方的压机框架上的光发射器和接收器，其将光束从垂直方向重定向到水平。 光束从发射器向下定向到冲头上的45度反射表面。 垂直于冲头的中心线的十字孔和与第一反射表面相对的第二45度相对面的反射器将光束返回到接收器。 因此，从发射器到第一反射器，通过压头，到第二反射器，然后返回接收器，实现光路。 相对的45度反射器优选地由具有围绕压头安装的光反射接口表面的45度碟形环提供。 由于发射和接收光路平行于柱塞的直线运动，轴环和反射表面随着压头的运动而上下移动，而是保持从发射器到接收器的光路。 遮光挡板连接到可滑动的冲头保持器组件的顶部，每当冲头接触到物体时，其将水平光束穿过冲头中心线。 因此，本光学系统代替了现有技术的硬接线冲头接触安全开关及其外部布线，从而提供了许多优点。

摘要： A label applicator for applying a label to the top surface of an object moving along a path adjacent to the applicator. The applicator is comprised of a label printer mounted for vertical adjustment on support structure attached to a moveable frame. The printer has a label feed position and is adjusted vertically on the support to set the label feed position to an expected median article height. A label transport assembly, attached to the frame, receives and retains the label and then moves vertically and laterally from a home position, above the label feed position, to an article intercept position, where it applies the label to the moving article. The controller learns the home position and positions the label transport assembly at the home position to pick up labels. The label printer, the label transport assembly, and the moveable frame are located along side the object path such that when the label transport assembly is in the home position, the object path is vertically unobstructed.
