  • Patent number: 4627528
    Abstract: For the conveying of work pieces from one treatment step to the next and for release after the treatment, gripping devices are arranged at gripper rails that can be lifted and lowered wherein the lowest and the highest position of the gripper rails can be adjusted via a pulley that can be placed against cam parts carried along by the slide of the press, via a step-up gear and a lever system. The change of the gripping devices is to be carried out together with the tool change. For this purpose, the gripper rails are led into the lowest position, which position can be adjusted via a regulating means independently from the position of the slide.

  • Patent number: 4625855
    Abstract: An apparatus for displacing profiled steel rods, especially concrete reinforcing rods, off a roll conveyor. The apparatus includes a plurality of bars interspersed with the rolls of the conveyor. At their undersides, the bars are associated with respective bearing bolts which are adapted to be received by horizontally aligned sockets so that in the rest position the upper surfaces of the bars are located below the level of the top of the conveyor. Piston and cylinder combinations are provided at each side of the conveyor to selectively raise one bearing bolt out of its socket while retaining the other bearing bolt seated in its socket, thereby to move the bars up above the conveyor and to create an inclined plane by which a rod traveling along the conveyor and engaged by the bars can be displaced and cast off the conveyor to one side or the other depending on the sense of inclination of the bars.

  • Patent number: 4624358
    Abstract: In the case of the fabrication of semiconductor devices, lead frames are successively transferred to the bonding position where semiconductor chips are bonded to a lead frame. To this end, a lead frame transfer device has been used. According to the present invention, there are provided means for adjusting the distance between a pair of guide rails which define the lead frame transfer passage and means for varying the transfer stroke or pitch of a device for transferring a lead frame along the guide rails. The means for adjusting the distance between the pair of guide rails comprises gage holes and gages or lead screws and nut so that one of the pair of guide rails is moved toward or away from the other guide rail depending upon the width of a lead frame to be transferred. The means for varying the transfer stroke or pitch of a device for transferring a lead frame comprises cams and sensors, and varies them through rotating a screw shaft combined with a nut by a motor.

  • Patent number: 4620628
    Abstract: A cable drive conveyor system in which a cable drive carried by idler sheaves communicates with conveyor carrier rollers. An endless cable is driven and is carried by the idler sheaves. At least one cable connector connects the two ends of the endless cable. A start pad covers the cable connector and has predetermined characteristics distinct with respect to the endless cable. A vertical urger which urges the idler sheaves towards the support rollers is mounted on adjustable pressure angle supports to cause the endless cable to generally maintain a constant pressure against the carrier rollers excepting when the start pad which covers the cable connector is carried by the idler sheaves.

  • Patent number: 4614264
    Abstract: For supplying tobacco from a redryer to a packer, the invention provides apparatus comprising four consecutive conveyors, the first conveyor operating continuously in one direction to feed tobacco from the redryer to the second conveyor, the second conveyor being reversible to act selectively as a holding conveyor and a supply tobacco to the third conveyor, the third conveyor being a weighing conveyor operated at a slower speed to weight and at a faster speed to deliver the weight quantities onto the fourth conveyor which carries the successive weighed quantities of tobacco to the packer. The conveyors are so controlled that the weighed quantities, when on the fourth conveyor, are spaced apart by intervals and the packer is operated through a packing cycle during each such interval.

  • Patent number: 4613035
    Abstract: Apparatus for removing bulk material from a dump comprises a horizontal scooping tube, which is mounted for rotation about its axis and provided with a plurality of buckets, which are distributed around the periphery and over the length of the scooping tube and protrude into the interior of the scooping tube through entrance openings formed in the wall of the scooping tube, and a conveyor, which extends within the scooping tube and serves to receive bulk material which has been dropped through the entrance openings by the buckets. In order to provide good conditions for the removal of material and to provide a simplified structure, the buckets are secured to annular collars, which are disposed at the entrance openings in the tube wall and radially outwardly protrude from the tube wall, and the buckets protrude at least with their backs through the collars into the interior of the scooping tube.

  • Patent number: 4611707
    Abstract: The disclosure describes a device for transferring a ball, skein or package from a winding mandrel to a freely projecting carrier arm mounted on a conveyor belt. This purpose is served by a wedge member, onto which the wound ball is moved by a gripping device and which subsequently moves with the ball towards the carrier arm. The wedge member and carrier arm both have a cross sectional profile which enables the wedge member to be displaced lengthwise of the carrier arm so as to pass over and beyond it and so the ball is pushed onto and remains on the carrier arm. In this way, the ball is exactly positioned and an arrow label may be inserted into the center hole of the ball with the aid of the carrier arm. Once the label has been inserted the labelled ball is withdrawn from the carrier arm.

  • Patent number: 4609096
    Abstract: A loader/unloader assembly for use with a vertical tiltable platform stores conveyor having a horizontal load position, a vertical stowed position and an intermediate inclined unload position. The load platform contains guide pins cooperating with a race track-shaped guide groove for selectably positioning the load platform in the three positions. When the load platform is in the unload position, a spring biased camming plate prevents displacement of one of the guide pins except upon application of a predetermined downward force to the load platform which serves to move the camming plate to an inhibit position and activate a switch to disconnect power from the conveyor system and stop conveyor movement. The force necessary to trigger the inhibit action may be selectably adjusted on the loader/unloader assembly.

  • Patent number: 4603768
    Abstract: Apparatus for transporting paper stacks has two spaced-apart transporting units each having a supplying conveyor which can accept stacks from a maker or feeder, an intermediate conveyor which can accept stacks from the supplying conveyor, and a receiving conveyor which can accept stacks from the intermediate conveyor for delivery to a packing machine. A third receiving conveyor is disposed between the receiving conveyors of the two transporting units and serves to deliver stacks to a third packing machine. The intermediate conveyors can be linked to each other for simultaneous movement transversely of the transporting units so that one of the intermediate conveyors registers with the third receiving conveyor while the other intermediate conveyor receives one or more stacks from the supplying conveyor of the corresponding transporting unit.
