Abstract:
Equipment for cropping, measuring and machining elongated work pieces, preferably rod-shaped or flat, comprises a computer which calculates the length of the work-piece and determines the machining processes, a device for clamping and conveying the work-piece, and a stationary clamping device for the latter, according to Claim one. The clamping and conveying device (5) is controlled by the computer according to simultaneous positioning tasks determined by the shaft encoder (3) or by the length-measuring device (74). A mobile carriage (63) conveys the material (7) through the diametrically opposed clamping device (67) when the latter is opened. However, when the material reaches the predetermined machining position, it is gripped by the clamping device (67) which then closes. The material is then cut or machined in a predetermined position of the sawing tool.

Abstract:
The mechanical hand (16) comprises, on one hand, a zone (46) for the support and sliding of a panel or slab (SP) in a horizontal working plane (WP) and, on the other hand, a handling gripper (36) which can move horizontally along and across the whole range of said supporting and sliding zone (46). The gripper (36) has a lower jaw (40) located below the working plane (WP). The support and sliding zone (46) is defined by retractable members consisting of an array of vertically moving pillars (48) with each of which are associated positive control means for causing them to perform selectively a travel independently of that of the other pillars between a raised position in which one of its upper support and sliding surfaces is in the working plane (WP), and a lowered position in which the surface is at a level which is lower than that of the lower jaw (40) of the gripper (36). Control means are provided which interconnect the means (Mx, My, Mz) for controlling the movement of the gripper (36) and the means for controlling the movements of each support (48) such that, when the gripper (36) passes through and stops in the zone (46) of the pillars (48), the pillars (48a) which are in correspondence with or in the vicinity of the gripper (36) are lowered such that they do not interfere with its lower jaw (40) whilst the other pillars (48) are raised in order to hold the panel (SP).

Abstract:
On each side of the frame of the machine (1) there is provided a clamping unit (2) to tighten the piece of which both sides are to be machined. A puppet head (5) is movable, either on the clamping unit or on the frame (1). In either case, both the puppet head and the clamping unit may be alternatively locked on the frame. The puppet head and the clamping block are connected by a ball threaded spindle (8) driven by a direct current motor (10). A microprocessor controls the motor (10) for the driving of the threaded spindle (8) as well as, alternatively, the locking and unlocking of the puppet head and the clamping block. The ball threaded spindle (8) allows on one hand the rapid feed from one work position to another of the puppet head and the clamping unit and, on the other hand, the slow feed for the machining. During these operations, the unlocked part is shifted with respect to the locked part.
