Definitions
- the invention relates to a rotary encoder having at least one track with a pulse train for generating signal pulses, a rotary machine with a rotary encoder, and two methods that relate to rotary encoders.
- Such rotary machines usually have a plurality of identical devices, which are arranged in a certain angular pitch on the circumference of the rotary.
- a labeling machine can have up to 60 or 70 turntables or more, with which to position vessels to be positioned to attach the labels on the vessels well-positioned.
- the angular distance between two such identical devices is called machine pitch.
- machine pitch In order to achieve the most accurate control in the treatment of the objects with the rotary machine, it is necessary to know the position of the rotor in relation to the machine pitch. This means that for a machine with a machine pitch of, for example, 10 °, this angle range must be known exactly with a resolution of / 4 ° C.
- Object of the present invention is therefore to provide a rotary encoder and a rotary machine, with which it is possible to construct as simple as possible machines with different machine divisions.
- Such a rotary encoder it is possible to obtain the information required about the position of the rotary in direct coupling of the rotary encoder to a shaft of the rotary. For this purpose, the appropriate reduction is selected according to the machine division.
- Such a rotary encoder can thus be used for different machines with different machine divisions.
- the rotary encoder has a track with a pulse train of 1 million pulses, 1 million signal pulses are generated in one revolution.
- a machine pitch of 3.6 ° ie, 100 identical Assemblies are provided
- a reduction of 10 000: 1 a signal pulse per rotation about a machine pitch.
- the output signal will be that of a conventional 5,000-pulse rotary encoder output on one revolution coupled to a respective transmission to rotate the machine rotates by a machine pitch once by 360 °.
- the rotary encoder In order to select the reduction ratios, a programming of the rotary encoder is advantageously possible. Programming can be done, for example, using a keyboard, switches, a remote control, a computer or similar. Furthermore, the rotary encoder preferably has a memory for storing the reduction information, so that the information does not have to be reentered or transmitted every time.
- the selectable ratios are advantageously in the interval from 2: 1 to 10,000: 1. Possible interval limits are 3: 1, 4: 1, 5: 1, 10: 1, 20: 1, 50: 1, 100: 1, 200: 1, 500: 1, 1000: 1, 2000: 1 or 5000: 1 ,
- a rotary machine according to the invention has a rotary encoder according to the invention.
- FIG. 1 is a schematic sectional view of a rotary machine
- FIG. 2 shows a schematic plan view of a rotary machine
- FIG. 3 shows a schematic representation of a rotary encoder
- Figure 4 is a schematic representation of a disc with a track of a rotary encoder.
- FIG. 1 shows a rotary machine 1 with a central shaft 2.
- a rotor 9 is fixed on the central shaft 2.
- On the circumference of the rotor 9 are, for example turntable 8, which can be rotated by servo motors 7.
- Such turntables 8 are used for example in labeling machines.
- Rotary machines are also used in fillers, blow molding machines, closing machines and others. used.
- a gear 4 is provided, to which a gear 5 engages, which is driven by a motor 6.
- a rotary encoder 3 is provided on the shaft 2. This is directly connected to the shaft 2 without intermediate transmission.
- FIG. 2 schematically shows a top view of the device from FIG. Evident is the rotor 9 with the turntables 8, which are distributed on the circumference of the rotor 9.
- the rotor 9 has 12 turntables 8.
- the angular distance a in this case is 30 °. That is, the machine pitch is 30 °.
- a rotary encoder 3 is shown schematically, as it may be provided at the lower end of a shaft 2.
- the rotary encoder 3 comprises a device 11 in which a track is provided with a pulse train with which signal pulses can be generated.
- the generated signal pulses are passed through lines 12 and 13 to a coaster 16.
- the transmitted in the lines 12 and 13 signal pulses 14, 15 have a phase shift of 90 °, so that from this direction of rotation of the track in the device 11 can be determined.
- the second uppermost output 17 has a reduction ratio 2: 1 and the next output a reduction ratio 4: 1.
- the other outputs may be equipped with phase-shifted signal pulses to determine directions of rotation or be assigned with other ratios.
- the output signal pulses may be the same length as those that are generated. They can also be longer than those generated, as shown in Figure 3 at the second and third signal output 17 from above. In this case, such signal pulses are advantageous whose high and low signal is the same length.
- the coaster 16 is programmable via an input 18.
- the coaster has corresponding memory devices for the programmed values.
- the coaster 16 is designed so that via the input 18, the reduction such as 5000: 1, for example, can be entered directly.
- the reduction factor is not input, but a measure of the machine pitch is input, such as a degree number corresponding to the machine pitch or the number of identical devices, such as 100 in the case of a machine pitch of 3.6 °.
- the coaster 16 then calculates the required reduction factor from this information itself.
- FIG. 4 schematically shows a track 19 which contains a series of pulses 20.
- the track 19 is arranged on a disc 23.
- the angle ⁇ of the machine pitch should be 30 ° as in Figure 2.
- the track 19 has a large number of pulses 20.
- a signal is to be generated which should be aligned in a certain position to the machine pitch, it is necessary to set the zero point of the signal with respect to the rotor.
- An example of this is a signal sequence that emits exactly one signal pulse upon rotation of the rotor about a machine pitch.
- the lines 22a and 22b also include an angle ⁇ 'corresponding to the machine pitch, but have a different zero point. By selecting the appropriate zero point so the signal can be set in in-phase relationship with the machine pitch.
- the method in which a reduction of the signal pulses to be output is selected in a rotary encoder for a rotary machine is usually carried out in the construction or in the conversion of a rotary machine.
- the corresponding rotary encoder can be programmed, for example, with a computer.
- the signals of a rotary encoder are output in proportion to the selected reduction ratio. This is a determination of Position of the rotary runner possible, the resolution may be sufficient to dissolve the position within a machine pitch.
