摘要： A material feeding apparatus for intermittently feeding a sheet or rod material in a predetermined length has a first gripper device having a first fixed gripper and a first movable gripper for cooperation with each other in clamping and unclamping a material therebetween, and a second gripper device having a similar construction as the first device and carried by a slide block provided for reciprocatory sliding movement along the path of feed of the material. The apparatus further has a first gripper actuating device having a first actuating member movable between a clamping position where it holds the first movable gripper at a position near the first fixed gripper and an unclamping position where it allows the first movable gripper to be spaced apart from the first fixed gripper, and a second gripper actuating device having a second actuating member movable between a clamping position where it holds the second movable gripper at a position near the second fixed gripper and an unclamping position where it allows the second movable gripper to be spaced apart from the second fixed gripper. The operation of the first and the second gripper actuating devices and the reciprocatory sliding motion of the slide block are effected in a timed relation by respective cams of a cam device, thereby to clamp, feed and unclamp the material.

摘要： A pneumatic feeder for punch presses and the like wherein a novel circuit and arrangement is incorporated in the feeder control system for causing the stock gripping means on the reciprocating feed slide to be released in response to the completion of each intermittent stock feeding stroke of the slide. This circuit and control arrangement includes a fluid motor means that is controlled by a pilot operated supplementary valve means which in turn is controlled by an air jet means that is arranged and adapted to sense the arrival of the feed slide at a predetermined position.

摘要： A pneumatically operated stock feeder for intermittently advancing stock into the work station of a punch press or the like and having an improved pneumatic control arrangement which incorporates three interconnected valves, namely a main three-way valve, an inlet pressure responsive valve means and a fluid pressure controlled exhaust valve means, for controlling the proper sequencing of the fluid motors that respectively produce the stock gripping, clamping and feeding actions of the feeder. The combination of the two pressure responsive sequence valve means control the operation of the main feed motor and are in turn controlled by the output of the main control valve; this control arrangement affording a high level of feed accuracy yet tolerating a relatively wide range of operator set-up inaccuracies and speed changes without significantly adversely affecting such feed accuracy.

摘要： A novel arrangement for the air circuit conduit lines of a pneumatically operated feeder for punch presses and the like. In order to insure that the stock gripping action of the feeder occurs before the initiation of the feed motion of the feed slide of the feeder a physically circuitous or roundabout path is provided for the air flowing between the control valve and the head end of the main feed cylinder. In this arrangement the main cylinder is located in the control circuit so as to be effectively disposed downstream of the stock grip cylinders when pressure air is directed to the main cylinder and so as to be effectively disposed upstream of said grip cylinders when pressure air is exhausted from said main cylinder. This arrangement will facilitate the establishment of the short but necessary time delay needed to enable the completion of the stock grip and release actions before movement of the feed slide commences.

摘要： A rotary power transfer component incorporated in the rotary to reciprocating motion conversion drive mechanism which operates the reciprocating feeder of a multiple slide machine increases the time available to the forming operation by correspondingly decreasing the feed time of the wire or ribbon stock during each cycle. The rotary power transfer component comprises a drive wheel and crank wheel mounted for respective eccentric rotation. The drive wheel, which is driven at a uniform rate of rotation synchronized to the forming operation of the machine, has an eccentric fixed pin which engages a radial slot in the crank wheel to thereby impart to the latter a synchronized cycle with varying speed of rotation within the cycle to be converted to a rapid advance feed stroke and a slow return stroke for the reciprocating drive of the feeder during which return stroke the forming operations are performed.

摘要： A strip-feed mechanism employing hold and feed gripper blades has a horizontal drive shaft with an adjustable eccentric assembly on it projecting from one side of a frame for easy access and adjustment. To accommodate extremely thin sheet material, the hold gripper blade is lifted from the sheet material during the forward portion of the stroke. The adjustable eccentric includes a cylindrical portion eccentrically mounted on a drive shaft and having a threaded periphery threadedly engaging an internally threaded wall of a bore through a cam member. The cam member and the threaded portion of the drive means are clamped together by a fastening means including a threaded plug and bolts. The threaded plug is threadedly received in the bore in the cam member, and the bolts are received in tapped holes in the cylindrical portion and bear against the plug to stress the mating threads on the drive member and cam member.

摘要： A pneumatic control arrangement for a high speed dual slide feeder for punch presses and the like; the feeder comprising two reciprocating feed slides which are respectively reciprocated by two main fluid motors and which respectively carry two gripper fluid motors. These four fluid motors are adapted to be sequentially controlled by only two control lines which arranged in a cross over type circuit and which have opposite pressure-exhaust conditions existing therein. This arrangement permits a substantial simplification in the valving and in the associated control lines over that normally required to produce the rapid successive alternate stock feed strokes of said feed slides; such thereby substantially reducing the cost of the feeder while increasing the reliability and durability thereof.
