Abstract:
Disclosed is a bar feeder, which is capable of reliably loading a bar onto a guide rail with a simplified structure. The bar feeder 1 comprises a stock rack 8, a guide rail 4 for guiding a bar to a bar machining apparatus, and a bar supply mechanism 32 for taking bars W one by one out of the stock rack 8 and supplying the taken-out bar W onto the guide rail 4. The bar supply mechanism 32 includes a lifting member 40 adapted to lift a downstreammost one of the bar W on the stack rack 8, a bar receiving member 42 adapted to receive thereon the lifted bar W and supply the bar W onto the guide rail 4, and a stopper member 36 adapted to holds a second-downstreammost one of the bar W to be subsequently supplied. The lifting member 40 and the bar receiving member 42 are adapted to be driven by a common moving device 44, in such a manner that the lifting member 40 is linearly moved in an upward-downward direction in conjunction with a swing movement of the bar receiving member 42. The structure designed to drive the lifting member 40 and the bar receiving member 42 by the common moving device 44 makes it possible to reduce the number of components for a driving section, and achieve structural simplification.

The main feature of the invention is that the driving assembly further comprises, on a portion of an active arm of the driving chain, actuator elements for removing the drive shoes from a panel sliding plane, to allow a processing tool to perform a lot of desired machining operations on the panels.
Abstract:
A method to remove pieces (14) cut off from bar-shaped workpiece material (5) by a cutting machine (1) is provided as well as an apparatus to carry out this process, wherein the piece (14) of the material (5) to be cut lies on a machine table (7) during cutting behind the cutting plane (8) in the direction of feed (9) of the material (5), is gripped between gripping jaws (12, 13) from behind the cutting plane (8) only. At the end of the cut, the cut off piece (14) is moved away from the cutting plane (8) by the gripping jaws (12, 13) in the material feed direction (9) and is tilted about an axis perpendicular to the material feed direction (9) such that its most recently cut surface is essentially horizontal and directed downward and that the piece (14) is then discharged by the gripping jaws (12, 13) by an essentially vertical motion downward onto an offload table (21).
Abstract:
An apparatus has first propellers (20) and second propellers (21) alternating with the first propellers. Each propeller has one or more helical biting edges (24a) protruding into a guide passage (28) through which a raw material (W) advances. The biting edges are formed along an inner periphery of each propeller at a predetermined lead angle so as to bite an outer periphery of the raw material (W). The apparatus further has a drive mechanism for rotating the first propellers (20) in a direction opposite to that in which the second propellers (21) are driven. The helical biting edges (24a) are inclined such that the raw material (W) may be forced towards a pressure vessel (2) by all the propellers, notwithstanding the opposite directions in which the first and second propellers ape driven, so that a strong thrust is applied to the raw material, without causing any torsion of the material which is being forced towards the pressure vessel.
Abstract:
The crank assembly of the advancing apparatus is eccentrically supported in an intermediate shaft. This intermediate shaft is in turn supported in an oscillating slide. Accordingly, the oscillating movement of the slide is superimposed over such of the driving pivot of the crank assembly. The intermediate shaft includes a cam disk. Due to the cam disk the intermediate shaft oscillates in operation and causes in turn the oscillating movement of the slide, which oscillating movement proceeds oppositely to the oscillating movement of the driving pivot. The sum of these two movements in the zones of the end positions thereof is accordingly zero. Accordingly, the driving pivot is at rest over a prolonged time span. Due to this prolonged rest period between individual feeding steps, elastical deformations of working structures and of the workpiece being worked upon, can attenuate and fade out prior to the working proper, and at the same time the length of the advancing is not subjected to a change. Furthermore, any clamping elements for the clamping of the workpiece can be lowered more slowly against the workpiece such that a lower energy of impact is produced. Conclusively, the workpieces are not subjected to a plastic deformation. The apparatus finds application specifically in punch presses.
Abstract:
An apparatus comprising a plurality of support members 6 mounted on a rail 5 and movable longitudinally of the rail, a housing 7 mounted on each of the support members 6 and rotatable about a support shaft 22 perpendicular to the length of the rail, and a contact ring mounted on the housing and rotatable about an axis perpendicular to the support shaft 22. An elongated material 31 is inserted through the contact rings 8 and rotated about its longitudinal axis as positioned longitudinally of the rail 5. The angle of inclination of the rotational axis of the material 31 relative to the axis of rotation of each contact ring 8 is variable by rotating the housing 7 about the support shaft 22. Lengths of elongated material of varying diameters are supportable each at its outer periphery by the outer periphery of each contact ring 8 at its axial one end and the other end thereof, with the center axis of the material positioned at a constant level, while the material is prevented from deflective revolution during its rotation. The elongated material 31 supported by the contact rings 8 is fed longitudinally thereof by a feed mechanism 60.
Abstract:
An automatic supply and storage system for machined materials includes; a feed conveyor which aligns and recycles a plurality of machined materials; a delivery conveyor which moves back and forth from the conveying area of the feed conveyor to advance and receive back the machined materials and to convey the machined materials for further processing in a direction transverse to the conveying direction of the feed conveyor; and a storage conveyor having a plurality of buckets which are intermittently recycled to store the machined materials, after further machining, in a prescribed bucket. The buckets have an aperture section which can be opened and closed in both the vertical and sideways directions. The system thus has the capability of feeding the machined materials to a machine tool, and after feeding a specified amount, sending the materials back to the feed conveyor.Also, a remnant selection device is positioned in the discharge end direction of the delivery conveyor to form a machined material transportation passage conforming to the quantity of machined material remnants. Remnants which are shorter than a prescribed length are rejected. A remnant collection hook which engages remnants which exceed the prescribed length and returns the remnants to the delivery conveyor then to the feed conveyor.A prestock passage aligns and stores the materials after processing and is movable to a push-out position in a direction transverse to the direction of delivery of the materials from the prestock passage to the storage conveyor.
Abstract:
The invention is concerned with a feeler unit for positioning sheet glass processing tools, which comprises a frame carrying at least one feeler roller piloting a tool holder head positioning motor, and a back-up roller engageable with the underside of a sheet glass edge being processed and rotatable about an axis which extends substantially parallel to the plane containing the glass sheet and substantially perpendicular to the edge being processed.A peculiar aspect of the invention is that a controlled movement of the back-up roller to and/or from the glass sheet, as well as controllable displacing of the back-up roller along a direction which is substantially parallel to a tangential direction to the glass sheet edge and perpendicular to the axis of the feeler roller are effected to vary the mutual position relationship between the feeler roller and back-up roller.

A drive device for rotation and axial displacement of each tube is provided. At least one of the scanning fingers is engageable in one of the cutouts upon the rotation and axial displacement of the tube so that the distance between the saw and the cutout can be determined and the tube can be accurately aligned with the saw.
