  • Patent number: 9534469
    Abstract: A ball dropper has a stack of trays that have solid portions for supporting a ball and open portions to allow a ball to pass through a tray. Fixed barriers limit the travel of the ball with the rotating tray to allow the ball to become unsupported so that it can be caught on the tray below. A stepper motor precisely makes the required incremental rotation to allow the addition of the next ball at the top. Once the trays are filled or the balls loaded are advanced such that the lead ball is on the last tray any further rotation will start to discharge the balls with each increment of rotation. The device is easy and cheap to fabricate and presents a reliable way to get jam free operation while having a housing that will tolerate the operating pressures in the wellbore.

    Abstract: A reduction to the traveling motion of bottles along a delivery conveyor in an intermittent motion decorating machine is provided by one of a pair of workpiece feed cams rotatably supported in a side-by-side relation to rotate about spaced horizontal axes lying in a common horizontal plane. The workpiece feed cams have feed cam tracks for receiving cam followers of each of plurality of vertical bottle carriers. One of the feed cam tracks reduces the speed of the bottle carriers from a relatively high entry speed corresponding to the through put speed in the decorating machine to the speed of the deliver conveyor for more densely populating the delivery conveyor with workpieces. Carrier transfer members at each of opposite ends of the workpiece feed cams transfer the bottle carriers from one to the other of the workpiece feed cams. A drive rotates the workpiece feed cams, carrier return cams and carrier transfer members.

Thereafter, the articles are advanced in a direction perpendicular to the position in space and toward a release station by means of a first conveyor equipped with pockets. The articles are caused to advance at a first linear velocity in such a way that each pocket receives an article and, at predetermined intervals, are accelerated to a second velocity for a predetermined duration between the arrival of one article at the transfer station and the arrival of the next article.
