Escapement for a stepless / adjustable, stepwise Feed with: fast reverse as a means of moving the

Transport slide with register cutting machines.

Devices on register cutting machines, which take over the advance of the transport carriage, as well as its fast return, have long been known in technology »

For example, it is common to use the linear movement of the Slide by two controlled pairs of jaws working in the form of a stroke exercise, which is arranged alternately with a on the transport carriage. EXemmschiene be brought into engagement, against; fixed adjustable stops is moved. One Another well-known solution provides for the implementation of the Gate push the application of a. Ratchet lock "before that is switched by means of a revolving Euro drive.

However, all of these facilities are flawed, which partly, from the required number of transfer elements or other constructive peculiarities result and in the course of time in an imprecise work. make job loss noticeable.

This is where the invention described below comes into play

Its purpose is to remedy the disadvantages listed above with simple Eliminate means and fail two independently acting in the carrier of the transport carriage

orderly Elemmgesperre before »one of which by the Clamping a permanently driven pushing or pulling element of any cross-section, the advance of the slide causes, while the other, counter-acting clamping lock, the transport carriage during the empty stroke of the push or Pulling organ as a result of the clamping effect of the balls or balls between the guide wall of the machine frame and the carrier of the transport carriage until it is again taken along by the pushing or pulling element in its predetermined position position and secures against an unintentional backward movement of a third force.

In the drawing, an embodiment of the invention is shown in principle: '

Mg. 1- shows the operation of the device, at the moment

Fig. 2 shows the standstill or the working position during the

the pushing or pulling element is returned. Pig. 3 shows the device in the inactive state during of fast rewind.

With 1 and 2 the table guide of the machine frame is referred to, with 3 in this longitudinally displaceable carrier of the transport carriage. The carrier 3 is used for recording the clamping lock 4 and 5 and for this purpose is laterally provided with wedge-shaped recesses, the tips of which are facing the direction of movement of the feed.

HemmgespBrre 4 with; Roll 6, spring 7 "and pressure piece $ Hests on the guide bar 1 of the machine frame, while IQ.emmgesperre 5 mitRolle-9, leather 10 and pressure: - '; piece 11 acts on a pushing or pulling element 12, the dureii one outside of the table guides 1 and 2, a constant "revolving EurTbeltrie" b 15 with link guide 14- "known type is given a linear movement. The guiding side 2 of the machine frame and the bearing 5 of the transport slide take over the guiding of the pushing or pulling element 12. A longitudinal recess penetrating the carrier 3 serves to accommodate a release rod 15, which is flattened on both sides and which, when rotated around its axis by means of a foot lever * Bowden cable and deflection lever (not shown), disengages the locking mechanism 4 and 5 due to its Foekenwlrkung via pusher "16 and .17. Carrier 5 is still under the influence of a G-weight 18 which counteracts the gate pushing device and which returns the transport carriage to its starting position when the two locking mechanisms 4 and 5 are triggered.

The device according to the invention now works as follows:

At the Eolissenführung 14 of the continuously revolving Zurbeltrlebes 15 the register height to be cut is specified represents »The resulting Eurbel radius is determined thus the stroke of the pushing or pulling element 12, its movement sinusoidal. Fig. 1 shows the device at the moment of the goal. The carrier 3 is through

The clamping action of the spring-loaded Eolle 6 is positively connected to the pushing or pulling element 1 2 and is taken along in the gate pushing direction. During this gate passage, the guide side 1 exercises a reverse on the locking mechanism 4. Effect because there the roller 9, which is under the influence of the spring 10, is pressed out of the wedge-shaped recess. This state remains until the reversal of movement of the pushing or pulling element 12 is initiated. (Fig. 2). At this moment there is a change in function of the two locking mechanisms 4 and 5. The weight 18 acting on the carrier 3 counter to the gate pushing direction now tends to return the transport carriage to its starting position. This undesired return movement is prevented, however, by the locking mechanism 4, whose roller 9, under the action of the spring 10, is known to wedge itself more firmly between the guide side 1 and the wedge surface of the locking mechanism 4, the greater the force of the weight 18 acting on it. Meanwhile, the pushing or pulling element 12 is returned in the opposite direction to the clamping action of the locking mechanism 5. Only at the moment of the renewed gate push of the carrier 3 by the pushing or pulling element 1 2 is the clamping effect of the locking mechanism 4 canceled and locking mechanism 5 brought into engagement again.

The gates described above are repeated in a constant rhythm until the entire feed distance is reached. In this front end position ^: is' by means of a barrel lever via Bowden cable, lever or the like. the release rod 15, which until then was facing the plunger 16, 17 with its flattened sides, rotated in its carrier guide. As a result of the jib effect of the release rod 15 are 'two -de plungers 1 6 and 1 7 pressed at the same time in their bore so far outward that they emmgesperre with their conical ends the pressure pieces 8 and 11 of the KL emmgesperre 4 and 5 in their leadership against the Push rollers 6 and 9 and bring them out of their inhibited position. After the two locks have been triggered, the weight 18 can freely act on the carrier 5 of the transport carriage and move it back into its starting position.

Since the trip rod 1 5 under the influence of a return spring it is possible at any time to roll the locking mechanism 4. and 5 without any effect by moving your foot accordingly to make and thus bring back the transport carriage accelerated, or the clamping of the rollers 6 and 9 can only be lifted a little so that the slide is braked drive into its starting position. The invention is also not exclusively to a certain cross-section of the pushing or pulling element 12 limited, rather can Any profile can be used, albeit advantageously a rectangular or round cross-section is proposed.

There is also the option of using the release device instead to mechanize a foot switch, so that a fully automatic operation can be guaranteed.

The advantage of the invention and the essentials consists only in the fact that without extensive transmission links and without the aid of adjustable fixed or movable stops, the proposed device Absolutely positive entrainment of the transport slide, an infinitely variable gate thrust for the individual register heights from theoretically Hull to infinity and that the feed movement of the transport carriage is sinusoidal he follows.
