Definitions
- the invention relates to a method for automatic Setting the grain structure of the comminuted material determining grinding gap one Impact grinder or an impact crusher.
- This Crushers have one with striking organs, especially blow bars provided rotor and as Counter tools so-called impact mechanisms and if necessary in addition also grinding tracks that are in operation with the Blow bars form a grinding gap next to the rotor speed is decisive for the degree of comminution.
- This grinding gap is due to both wear Blow bars as well as the impact units and the grinding tracks gradually increased in size during operation so that the generated Product becomes coarser.
- the necessary circuits switching on the actuator for the impact system, reversal of movement after signaling through a microphone when touched, switched off of the actuator after the desired long return movement of the impact system) were made by hand.
- the invention is based on the objects, this known Process so that these human Shortcomings are eliminated and that Adjustment of the impact mechanism can happen automatically. It clears the way for an impact mill that from switching on your drive motor and starting it up the feed device for the comminuted material can be operated completely automatically.
- Signal a) ensures that the impact mill is actually free from comminuted material, through the signal b) that the impact mill rotor actually rotates.
- the modified signal c) ensures that the reversal of movement actually from the repetitive sound is controlled by striking the blow bars is generated against the impact mechanism and not by similar noises, which are caused by about Material feed stones falling into the impact mill or other coincidences.
- An advantageous embodiment of the invention Procedure results when the movement of the Impact mechanism on the rotor to when a first occurs, from a sub-signal originating from a hard noise immediately is stopped and resumed if there are no more Partial signals follow, and that the movement is reversed will when a certain strength and length or a certain minimum number of partial signals in a time unit the computer the mutual touch of Displays shredding tools.
- the adjustment method according to the invention for the impact device an impact mill enables one completely automatic operation of the impact mill when the computer a program (software) is assigned to the material to be shredded is coordinated. It determines in at what intervals a new adjustment of the impact mechanism takes place and it causes the material feed in each case stopped before and then started again is set.
- the comminuted material is relatively soft, so that the wear is very low, it may be enough if at the start of work, before the material to be crushed is given up is, the impact mechanism setting according to the invention takes place and no correction needed during the day is.
- the computer by means of it assigned interchangeable or influenceable program the distance of the impact device to the rotor according to a desired grain structure determined and accordingly an adjustment of the impact mechanism (the grinding gap) automatically. This allows the grain structure of the shredded goods can be changed particularly easily.
- the signals b) and c) from a common one Microphone derived by the outgoing from the microphone Signal after amplification divided into two channels becomes.
- the computer is for everyone Setting the grinding gap the distance traveled of the adjustable impact mechanism saves and compares with pre-programmed values and with the help of the program entered into it Wear rate or state of wear, the rest Operating time or the need to change the Shredding tools that shred the produced amount Good per shredding tool kit and the like Displays data to the operating personnel or into one parent, calculator there. This makes it a fully automatic Operation of the impact mill possible the only by changing worn out shredding tools by hand or by any other repair work is interrupted.
- the impact mechanism is driven in the sense of an approach to the rotor in progress set, the elastic intermediate member is from Drive energized. Then dissolves, e.g. B. as a result of occurring in the crushing work Shocks, the deadlock, so the impact under the action of the tensioned pontic hurled against the rotor that it was in the impact area the blow bars gets what destruction at the impact mill.
- an additional Intervention in the above marked Procedure provided by the drive of the impact system is stopped when moving towards the rotor if that elastic intermediate member compressed from the drive side becomes.
- the Computer through the program or after a warning signal one or more times also by hand control
- the impact mechanism can be moved back and forth, until readjustment as a result of the jamming being released of the impact mechanism to the rotor.
- the elastic intermediate member can in a known manner (DE-A-35 25 101) but also by a pneumatic Be formed spring, then the warning signal by the when the air cushion is compressed by the Pressure increase triggered on the drive side becomes.
- a pressure gauge in the like Context is part of DE-A-35 25 101, Fig. 2 21 known, but it serves in contrast to the present Use to do this, the pressure of the elastic Maintain pontic.
- the impact mechanism with the help a microphone provided on the impact mill housing by a drive unit to the desired distance is adjustable to the rotor, according to the invention is used Facility through which the microphone Signal amplified and then distributed over two channels, of which the signal of one channel is transmitted via a Signal decoupler with a low trigger threshold and that Signal of the other channel via a signal decoupler is fed into a computer with a high trigger threshold, which is programmed so that - provided that the Low trigger threshold overcoming signal reached him - after receiving one from switching off the material feed of the impact mill, delayed Signals the drive unit of the impact system in the sense switches on an approach of the impact mechanism to the rotor, this movement reverses as soon as the high one Signal crossing the trigger threshold in multiple sequences reached, according to a program entered into it the return movement stops and the material feed again starts.
- the signal decouplers that represent the trigger thresholds retriggerable timers, which convert the frequency signals into high signals and down a constant high signal to the minimum frequency Give calculator.
- the impact mill shown in Fig. 1 has a housing 1 on, in which a rotor 2 by a horizontal Axis 3 is rotatably mounted. It is with four blow bars 4 provided. Above the rotor 2 is in the housing 1 an impact mechanism 5 is pivotally mounted about an axis 6. It is on the side facing the rotor with wear plates 7 armored. Its lowest wear plate 7a forms with that of the outer edges of the blow bars 4 imaginary cylindrical surface described in circulation 8 a grinding gap 9 which, depending on the pivoting position of the Impact unit 5 is more or less tight. The panning the impact mechanism 5 takes place, as also shown in FIG.
- a microphone 18 is provided, which the recorded noise of the impact mill in electrical Converts signals.
- these signals pass through a preamplifier 19 and an amplifier 20 and are then in two channels 21, 22 passed to two signal decouplers 23, 24 with different settings Trigger thresholds.
- the signal decoupler 23 has a relatively low threshold that the at When the impact mill is idling, the resulting noise lets through.
- the corresponding signal is in a retriggerable Time switch 25 in an upcoming time High signal processed, which reaches the computer 27.
- the signal decoupler 24 has a high threshold and therefore only lets through hard signals such as z. B. from the striking of the blow bars 4 against the impact mechanism 5 originate, and then via a retriggerable Timer 26 also as a high signal to the computer 27 arrive.
- the computer is still under the influence of inductive Proximity switch 28, the position of the Impact system depends and the basis for the dimensioning that of the computer about the respective needs adapted to the shredding work, not shown Program (software) caused via a geared motor 10 adjustments of the impact mechanism to the rotor 2 forms.
- Program software
- the computer also switches according to the Program the feed device for the shredded Well off and on again, with the receipt for switching off with a time delay with contactors provided control cabinet 29 takes place. Through in that Control cabinet 29 provided organs can be more Interventions in the operation of the computer 27 by hand be made, unless this by the Computer-assigned program already done.
- the calculator 27 is also assigned as a proximity switch trained switching element 15, which ensures that the impact mechanism 5 can also be adjusted.
- the now following adjustment process of the impact mechanism 5 exists from two phases.
- the impact system slowly approached the rotor 2 by the electric motor 10. Is it so close to the rotor that the blow bars 4 against the foremost wear plate 7a of the impact mechanism beat, so arise at regular intervals (four impacts per rotor revolution) hard impact noises, which are picked up by the microphone 18 and as strong signals be passed on, which are suitable, the threshold the signal decoupler 24 to overcome and as a corresponding High signals get to the computer 27.
- the retriggerable Timer 26 ensures that the Computer only reacts to these signals if one certain minimum number per time unit of these impact noise signals occurs and thus correctly identified is that it is striking the Blow bars against the impact mechanism and not around from others Causes the resulting noise. There are the retriggerable timer has a constant high signal to the computer.
- the computer can, for. B. by means of a pulse counter 17, 28 in the actuator 10 of the impact mechanism 5 is installed, the number of for moving the Impact mechanism on the rotor 2, 4 required revolutions of a gear part and then - from this Number starting from zero of the impact mechanism - the gearbox turn back a number of revolutions that the desired new distance of the impact device from the rotor, thus corresponds to the desired gap width 9.
