Description

The invention relates to an adjustable electronic counter with variable counting ranges.

It is known for knitting machines, especially for flat knitting machines, the goods with repetitive Make patterns to use counters that count these pattern repetitions so that the Musteiinformation does not have to be included in the program more than once.

In flat knitting machines, repeat counters are used for this, through so-called counting disks being represented. These counting disks have a predetermined total counting range, which is defined by a Number of holes is shown. By inserting shank screws into these holes you will Partial counting areas created which indicate the number of repeats of the repeat.

So if on the counting disc the choice of the individual Partial counting ranges were hit by the arrangement of the set screws, the number of the pattern repetitions cannot be changed arbitrarily, because by reducing the size of the first Partial counting area would be the second partial counting area

S are accidentally enlarged and vice versa. Therefore you have to z. B. when reducing the Number of repeats in the first counting area, for example by five, the following set screw that the Beginning and size of the repeats in the second

ίο counting range determined by the same amount, namely by five holes on the counting disk in the direction of the first counting area. Just like that must be used with the other set screws, which determine the following number of repeats, because the distances to each other must always remain the same. This procedure is very cumbersome and time-consuming, especially because a change in the partial counting ranges cannot be changed on a running basis Knitting machine can make.

ao If the conventional cardboard machine is used on a knitting machine by means of an electronic control replaced, the mechanical report counter must also be replaced by an electronic one.

This counter has compared to the usual

The counting disc has the advantage that it is much faster can be set, the set counting ranges can be rejected immediately and directly and that A change in a counting range does not result in a change in the subsequent counting ranges, such as it is the case with the previously used counting disks.

There are already known presettable counters with different selection ranges. With these counters a switching signal is always emitted when the preset number of a selection range is reached. at With these counters, the number and size of the selection areas cannot be changed, as is the case with the present one Task would be beneficial.

According to the invention, this object is achieved by that the selector switches are linked to the counters so that at a certain position the Selector switch when switching from one counting range to the next only an overflow signal and none Switching signal occurs, in all other positions of the selector switch an overflow and switching signal occurs. The counter is therefore constructed in such a way that the counting areas can be added to one another, so that larger counting capacities are possible by combining the individual dialing ranges, the largest being Counting capacity arises when only one counting area is created. About lining up the selector switches to enable, these have a position in which a switch to the next selector switch occurs, but no switching signal is given.

Such a counter can preferably consist of two decadic counters with a total capacity of 100 counting steps and 10 selector switches with 10 selector levels each and an additional position for lining up be constructed.

Some possible combinations are given below to explain the above embodiment.

An exemplary embodiment of the subject matter of the invention is shown in the drawing.

The drawing shows a circuit diagram of the subject matter of the invention.

A counter Z according to the invention is shown in the circuit diagram shown, which corresponds to the above. The total capacity is ninety-nine counting steps, and there are ten adjustable sub-areas with counting areas of up to nine.

The counter Zl is always switched by a signal at the input ^ by one digit, z. B. at the end of a knitted repeat. The counters Zl and Z2 are initially triggered by a signal on the input /? brought to their starting position. In the case of counter Zl , resetting takes place via the OR gate G12. The ten outputs of the counter Zl go to ten positions of ten selector switches WO to W9. An 11th position of the selector switch, the overflow position Ü, is used to line up counting areas.

The AND gates GO to G9, together with the counter setting of counter Z2, determine which selector switch is selected. The counters Zl and Z2 are brought to their starting position, so the selector switch WO is in action. The counter Zl is switched gradually from 0 to 9 by signals at the input Λ. When the number set on the selector switch WO is reached , a signal occurs at the gate GO which resets the counter Zl to zero via the gates G10 and G12 now the selector switch selects Wl. The signal that brings the counter Zl into its starting position also occurs at the output and causes a switch to the new sample report.

If the selector switch WQ is in rigidity Ü and the counter Zl reaches position 9, the gate is GO

^ao blocked, and no signal reaches gate 10. However, a signal · .- · occurs at gate 11, which advances counter Z2 by one position . On the other hand, no signal for a report jump C occurs at output C. This means that the selection area is WHERE and the

^a 5 area Wl combined into one selection area. If the selector switch in the selection area Wl were in position Ü , the selection area Wl would also be added to the previous selection area WO and Wl . This can be done in all possible combinations. This results in a flexible counter which largely meets the requirements of a report counter and can be used in an electronically controlled machine.

When the switch B is actuated, the rows of numbers in the counters are reset to the initial value zero by the resetting device rs.
