摘要： PURPOSE:To reduce the space for conveyance, simplify connecting work and promote its efficiency, by using a partition plate to divide a belt conveyor into an unfinished workpiece lane provided with an intake unit and a finished workpiece lane provided with a takeout unit and by installing a grabber between both the units. CONSTITUTION:When an unfinished workpiece V is supplied on an unfinished workpiece lane 1a, the direction of movement of the workpiece is shifted toward an outer edge by a gate 5 so that the workpiece goes into an intake chute 6 and drops down. A push-out unit 7 is then operated to push out the workpiece V forward to hole it by a grabber 15 and send the workpiece by an arm 14 to a numerical-controlled machine to turn one side of the workpiece. After the turning, a grabber 16 is moved to the finished workpiece W by the arm 14 to hold the workpiece and take it to the chute 9 of a takeout unit 8 to roll down the workpiece on an inverting chute 12. If the workpiece W, which is conveyed with its other side face-up after being transferred onto a finished workpiece lane 1b, needs to have the side machined, the side is processed by a lathe at an other-side-machining station.
摘要翻译：目的：为了减少运输空间，简化连接工作，提高效率，通过使用隔板将带式输送机分为未设置的工作车道，设有进气单元和设有取出单元的成品工件车道，并安装两个单位之间的抓手。构成：当未完成的工件V被供给到未完成的工件车道1a上时，工件的移动方向通过门5向外边缘移动，使得工件进入进入槽6并且下降。然后操作推出单元7向前推出工件V以通过抓取器15将其打孔，并通过臂14将工件发送到数控机器以转动工件的一侧。在转动之后，抓斗16通过臂14移动到成品工件W，以保持工件并将其带到取出单元8的斜槽9，以在倒车槽12上滚动工件。如果工件W，在被转移到成品工件车道1b上之后，其另一侧面向上传送的侧面需要侧面加工，侧面由另一侧加工站的车床加工。

摘要： PURPOSE:To permit the jaw of a chuck of a machine tool to be replaced automatically by the operation of a tool rest and the chuck. CONSTITUTION:A magazine 3 index-revolves to index a holder 30 for storing replacing jaws 2a to a replacing position X1. Then, the holder 30 is advanced to A position, and the replacing jaw 2a is inserted into a chuck 1, and the holder 30 returns again to the original position B. At the same time when the replacing jaw 2a is inserted into the chuck 1, a cam and an engagement piece operate, and said engagement piece is locked, and the jaw 2 is held fixedly. Therefore, replacement of jaw is automated, since the replacing jaw 2 in the magazine 3 is inserted by the operation of a housing through NC instruction.
摘要翻译：目的：通过刀架和卡盘的操作，可以自动更换机床卡盘的夹头。构成：杂志3索引 - 旋转以索引用于将更换爪2a存储到更换位置X1的保持器30。然后，保持器30前进到A位置，将替换爪2a插入到卡盘1中，并且保持件30再次返回到原来的位置B.在更换卡爪2a插入卡盘1的同时凸轮和接合件操作，并且所述接合件被锁定，并且夹爪2被固定地保持。因此，由于通过NC指令通过壳体的操作来插入料仓3中的更换夹爪2，因此更换颚部是自动化的。

摘要： PURPOSE:To align the position of a chuck held by holding arms with the position of each spindle, in a chuck transferring device, by variably adjusting the pivotal positions of the chuck holding arms. CONSTITUTION:A transfer body 8 is rotatably supported on a base 1, a plurality of chuck holding arms 12, 12' grip a chuck pivotally supported, a plurality of chuck pushing arms 15 resiliently press the chuck through a press spring 25, and an actuating cylinder 3 performs the gripping of the chuck holding arms and as well the pressing of the chuck pushing arms. A pivotal shaft 18 supporting the holding arms is formed as an eccentric shaft, and the eccentricity of the pivotal shaft is possible to be changed, that is, the eccentricity of the pivotal shaft for the holding arms is sequentially adjusted with respect to the position of one spindle which has the longest distance to a turning shaft 2 among the positions of the spindles, thereby the misalignment between the axis of the chuck to be gripped and the axis of each spindle is limited to the minimum.
