Definitions
- the invention relates to a timer with a switching element on which a suction cup is arranged, with a counter body against which the suction cup to form a Vacuum chamber can be pressed, with air contained in the suction cup being displaced with an air inlet opening in the vacuum chamber, the cross section of which determines the Release time of the suction cup from the counter body is preferably adjustable, and with a Restoring device whose restoring force is less than the suction force of the against the The suction cup is pressed against the counter body.
- Such timers are used, for example, to trigger or terminate a Process used when relatively short switching times are specified, only mechanical Energy sources are available, etc.
- a non-exclusive area of application lies in the motion control for transport rollers of paper towel dispensers or the like.
- the air inlet can be changed with the help of the adjusting screw, but this is not always effective if the switching cycle accelerates once experience and then again should run in the same setting.
- the vacuum chamber has a ventilation opening with an in Assigned closing position acted upon, sealing closure element, so that a any reduction in the duration of the switching time by raising the locking element becomes possible.
- the vacuum chamber thus has two openings, namely the one specified Switching time determining air inlet opening and the shortening of these Ventilation opening, the closure element of which is operated, for example, by hand.
- a preferred embodiment provides that the counter body is a solid plate, and the ventilation opening provided with the closure element is provided in the counter body is.
- a housing-fixed, non-compliant plate improves the sealing System of the closure element, which is arranged in particular on a lever on the one hand a return spring and on the other hand against the return spring working actuator attacks.
- the timer has a housing or a support frame 1 on which a plate or the like. is provided as a counter body 11 to a suction cup 3, which on a Switching element 5 is arranged.
- the switching element 5 is displaceable in a guide 2 mounted and has a bore 6 which is arranged in a within the suction cup 3 Air inlet opening 9 of small cross section ends.
- the outer end of the hole 6 preferably carries a needle valve 7 with an adjusting screw 8, the rotation thereof the inflow speed of the air in the vacuum chamber 10 changes.
- a Return spring 4 acts on the switching element 5 opposite to the suction force of the Suction cup 3, so that the switching element 5 from the position shown in FIG. 1 after sufficient Air access is transferred via the opening 9 in the position shown in FIG. 2.
- the counter body 11 is also a ventilation opening 12 which is associated with a closure element 13.
- the closure element 13 is provided with a seal 14 and on a lever 15 arranged, which is pivotable about an axis 16.
- lever 16 engages Return spring 17 which presses the closure element 13 against the ventilation opening 12, and on the other hand an actuating element 21, with the aid of which the ventilation opening 12 can be opened and counteracts the return spring 17.
