An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

A rocker arm includes an outer arm defining a stop aperture with a stop surface; an inner arm which selectively pivots relative to the outer arm; a latching mechanism which switches the rocker arm between a coupled state in which the inner arm is prevented from pivoting relative to the outer arm in a first direction and a decoupled state in which the inner arm pivots relative to the outer arm; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a second direction which is opposite from the first direction; and a stop pin fixed to the inner arm and extending into the stop aperture such that the stop pin is circumferentially surrounded by the stop surface and such that the stop pin within the stop aperture limits the extent to which the inner arm pivots relative to the outer arm.

A method for structuring at least one sliding surface (4) of a machine element (1), wherein the at least one sliding surface (4) is provided by a first structuring method with a first microstructure (5) for holding lubricant. To be able to now realize the best possible sliding properties for the sliding surface, during the course of a second structuring method, recesses are formed in the at least one sliding surface (4), by which a second microstructure (6) is defined with less depth in comparison with the first microstructure.

A tappet (1) having a tube-like housing (2), which in the region of one of the end faces (3) thereof receives a roller (5) running on a pin (4) and serving for contact with a periodic stroke generator. The pin (4) is mounted via the ends (6) thereof in a flat (8) that is indented from an outer surface (7) of the housing, wherein in the housing (2), axially beneath the roller (5), means (9) are provided for an at least indirect bearing of a tappet follower member. The housing (2) is formed of an extruded profile having profiling on the inner surface (10) of the housing (2), wherein, viewed in a circumferential direction of the housing (2), at least twothick-wall profile segments and two thin-wall profile segments (11, 12) are present. The thick-wall profile segments lie diametrically opposite each other and the thin-wall profile segments lie diametrically opposite each other, and the flat portions (8) are located in the thick-wall profiled segments (11).

A mechanical system, forming a cam follower or a rocker arm, the mechanical system comprising: a support element; a pin extending between two opposite ends along a first axis and supported by the support element; and a roller movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element includes an inner cavity in which the roller is at least partially arranged and which is adapted to contain an oil bath for lubricating the roller. Examples of applications for the mechanical system include a follower device, an injection pump or a valve actuator.

摘要:
A system for controlling variable valve actuation in an automobile engine. A first cam has a first lift profile and a second cam has a second lift profile. A rocker arm assembly engages the cams having a first arm for riding on the first cam, and a second arm for riding on the second cam. The second arm has an activatable latch capable of securing the second arm to the first arm when latched. When the first arm is secured to the second arm, the rocker arm assembly achieves a first lift profile and when the first arm is not secured to the second arm, the rocker arm assembly achieves a second lift profile. A non-contact sensor mounted adjacent the rocker arm assembly is adapted to monitor and create data indicative of whether the first arm is secured to the second arm.
摘要:
An epicycloid planet gear cam that converts rotational movement of a driveshaft into linear movement of an output device is disclosed. An epicycloid planet gear is assembled inside a stationary housing with an internal stationary ring gear. A driveshaft eccentric is connected to a driveshaft. The driveshaft eccentric rotates freely in a mounting hole of the epicycloid planet gear. When the driveshaft rotates, the driveshaft eccentric engages the epicycloid planet gear against the stationary ring gear and causes the epicycloid planet gear to rotate. A cam follower pin attached to an output device is held against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the raised cam track height or the slotted cam track distance from the center of the epicycloid planet gear causes the cam follower pin to move up, down, in, or out thereby moving the output device.
摘要:
A tire inflation system including a drive mechanism having a rotational axis, a pump cavity positioned a radial distance away from the axis of rotation, and a force translator coupling the rotational axis to the pump cavity. The drive mechanism includes a cam comprising an arcuate bearing surface having a non-uniform curvature, the cam rotatable about the rotational axis, and an eccentric mass couple to the cam that offsets a center of mass of the drive mechanism from the rotational axis. The pump cavity is rotatably coupled to the cam, wherein the pump cavity includes an actuating element and a chamber. The force translator couples the arcuate bearing surface to the actuating element, wherein the force translator includes an axis having an arcuate position fixed to an arcuate position of the pump cavity.
