摘要： PROBLEM TO BE SOLVED: To provide components to be mounted on a bar feeder having a dividing plate so that the bar can be smoothly taken out of a material shelf. SOLUTION: The material shelf 10 and the dividing plate 8 have a first component 20 and a second component 22 to be removably mounted, respectively. The first component 20 has a stopper 20b that projects upward from a tilting shelf surface of the material shelf 10 and holds the bar W on the shelf surface, and the second component 22 has a bar receiving surface 22g expanding from a bar receiving region A to the under part of the bar W adjacent to the stopper 20b. The dividing plate 8 rotates in the second direction, thus the bar W is lifted up by the bar receiving surface 22g beyond the stopper 20b, and guided to the bar receiving region A by the bar receiving surface 22g.

摘要： PROBLEM TO BE SOLVED: To provide an automatic bar supply machine realizing energy savings by omitting useless motions and capable of shortening the time required for feeding. SOLUTION: This automatic bar supply machine is used to feed bars to be worked forward to a bar working machine by primarily sending them along a guide rail by means of primary feed members and then secondarily sending them by means of a secondary feed member. The guide rail has a primary feed guide rail portion for primarily sending the bars by the primary feed members and also has a primary send transmission provided with a pair of bodies of rotation for the primary feed disposed in the longitudinal direction of the guide rail portion and a primary feed endless member wound on the bodies of rotation. The two primary feed members, leaving a substantially constant space between them, are mounted on the endless member. The machine is characterized in that the primary feed members make circulating motion, or they move forward for the primary feed in the guide rail portion in keeping with the running motion of the endless member, and after they get out of its front end, they enter the guide rail portion from the rear side.

摘要： PROBLEM TO BE SOLVED: To provide an automatic bar supply machine having a material shelf with a simple structure, capable of smoothly supplying bars to a guide rail, capable of reducing a noise problem, and capable of reducing load of a worker. SOLUTION: In this automatic bar supply machine, the bars are supplied one by one from the material shelf juxtaposed with the guide rail to the inside of the guide rail extending to a bar working machine and the bars are fed along the guide rail by a feed member. The material shelf has a shelf surface upwardly inclined toward the downstream side relative to the flowing direction of the bars flowing on the shelf surface toward the guide rail and has a push member for pushing the bars in parallel with the guide rail along the shelf surface. The machine is characterized in that the plurality of bars placed in a line on the shelf surface are pushed by the push member from the upstream side to cause the bar on the downstream end to be pushed out, thus supplying it to the inside of the guide rail.

摘要： PROBLEM TO BE SOLVED: To restrain a rod material from causing rotational deflection by fitting a control means for controlling opening and closing of respective supporters which involve rod material clamping areas separated from a rod material restraining part so that they may be closed. SOLUTION: When a bar material W passes through roller type damper units 14a and 14b, the bar material W is clamped with rollers. When a finger chuck 10a rests in the rod material clamping area of a roller type damper unit 14a or 14b, the roller type damper unit 14a or 14b capable of clamping the finger chuck 10a is kept at an open position without closing. As a result of the finger chamber 10a passing through the roller type damper unit 14a or 14b completely, the respective rollers are brought into contact with the outer periphery of a push rod 10 to retighten the push rod 10 when the push rod 10 has passed through the roller type damper unit 14a or 14b.

摘要： PROBLEM TO BE SOLVED: To reliably and smoothly feed a small bar, especially an extra fine bar, to an automatic lathe. SOLUTION: An automatic bar feeder 1 to feed a bar W to an automatic bar finishing machine comprises a moving guide 14 to receive a bar in an initial position; a bar feeding member 13 movably arranged in the moving guide; a member drive device 3 and a moving guide drive device to press and energize frontward the bar feeding member and the moving guide; a drive control device 5 to control forward movement of the bar feeding member; and a guide coupling device 6 to regulate relative movement between the bar feeding member and the moving guide. The moving guide and the bar feeding member are integrally advanced in such a state to contain the bar W in the moving guide at an initial feed process. The drive control device and a guide coupling device cause relative displacement between the bar feeding member and the moving guide, causes relative forward and backward movement of the bar feeding member to and from the moving guide, and causes integral backward movement of the bar feeding member and the moving guide to an initial position.

摘要： PROBLEM TO BE SOLVED: To simplify the manufacturing process and management of a finger chuck provided with an elastic holding member while clamping the rear end of a bar material and the finger chuck so that both can be smoothly separated from each other. SOLUTION: In a method for manufacturing a finger chuck mounted to the front end of a bar material supply member, the outer periphery of the end of a bar material WC to be clamped by the finger chuck 10 is formed with a plurality of recesses 42. The bar material is inserted into a bar material inserting hole of the finger chuck to form a resin molding core WC in the bar material inserting hole. The recesses are disposed circumferentially of the bar material at a predetermined interval. Fluidized resin material is infused into a gap formed between the outer peripheral surface of the core WC and the inner wall surface of the bar material inserting hole, and an opening part of the bar material inserting hole is closed with a jig 30 provided with the bar material inserting hole through which the bar material can be inserted. The inner wall of the bar material inserting hole, the outer wall of the core and the opening part closing wall surface of the jig define the resin molding region in the bar material inserting hole.

摘要： PURPOSE:To prevent noise or vibration generated when a bar falls from a material shelf, simplify a structure of a new material replenishing mechanism, and improve a degree of design freedom in the arrangement or a structural design of a rotary swing preventive device or the like. CONSTITUTION:A new material replenishing device is arranged on the opposite side of a material shelf 8 to the bar feed axis X-X, and has the rotary axis 10 extending substantially in parallel to the bar feed axis, a swinging member 20 to rotate with the rotary axis as its center and a driving device 30 to rotate the swinging member in the first and the second rotational directions, and the swinging member has a prescribed width, and extends in the direction substantially orthogonal to the bar feed axis. The swinging member has a pushing-up part 21 having a bar pushing-up plane 23 butting a bar situated in the lowest end part of an inclined plane of a material shelf by first rotational directional rotary motion, an inclined part having an inclined plane 24 which continues with the pushing-up plane and extends toward the rotary axis and a bar receiving part 25 which has a bar guide surface continuing with the inclined plane and can be arranged with the bar feed axis by second rotational directional rotary motion.

摘要： PURPOSE:To provide a rod member swing stopper which is capable of supporting a feeding arrow effectively without preventing the movement of the feeding arrow by a rod member working machine after the rear end of the rod member passes. CONSTITUTION:A rod member swing stopper 10 is provided to a rod member supplier. There are provided swing-stopping rollers 14a-14d which are brought into contact with the outer circumferential surface of a rod member so as to suppress the rotational swing of the rod member (W) and hold the rod member in a rotatable manner, and a link mechanism and a fluid-actuation type cylinder device 17 to release the roller when the rear end part of the rod member passes. There is provided to the rod member swing stopper 10 a re-tightening device 30 to close the rollers after the rear end part of the rod member passes. The re-tightening device is provided with a link mechanism to move the rollers toward a feeding arrow 25 and a stopper screw 32 and a slider 34 to restrict the movement of the rollers when the rollers move to the specified location close to the outer circumferential surface of the feeding arrow.
