Definitions
- the invention relates to a method for comminuting chips in a comminution space between a driven, rotatable in both directions, equipped with shear elements, horizontal shaft and associated counter-shear elements, wherein chips entered from above are crushed and discharged downwards over a perforated screen floor and blocking components cause a wave standstill to be discarded after reversing the wave.
- the invention further relates to two devices for carrying out the method according to the invention.
- a vertical chip breaker for steel or metal chips with a coarse part ejection element is known from EP 0 717 663 B1.
- This single-shaft crusher consists of a receiving funnel and a grinding funnel which adjoins the bottom and which has rice blocks arranged around the circumference, at the edges of which the rice knives attached to a rotating cutter head can be moved.
- a grinder follows below the grinding funnel.
- an ejection channel for coarse parts which can be opened by means of a power-driven channel slide, is provided. If there is now a large part between the chip material, this lies on the grinder and is rotated by the cutter head together with the chips until it blocks the Knife head comes.
- a slow reversing process is initiated and the coarse part ejection element is opened so that the interfering elements can be transported from the cutter head to the ejection and through it.
- a disadvantage of this design is that it cannot be used for horizontal chip breakers.
- the rotary movement of the cutter head is impaired, no distinction is made between dense tufts of chips and coarse parts or combinations of the two.
- dense tufts of chips can often lead to blockage. These tufts are also removed via the ejection and thus removed from the shredding process.
- the object of the above invention is now to provide a method and two devices of the type mentioned at the beginning, wherein a horizontal chip breaker is provided which divides the blocking components into groups, e.g. dense tufts of chips, pure coarse particles, and each group assigns a defined reversing process and, if necessary, discharge from the shredding area via a coarse particle ejection element.
- groups e.g. dense tufts of chips, pure coarse particles
- a method in order to achieve the object, in which the speed of the change in the load of the driven shaft, which is fitted with shear elements, is recorded, the change in the load taking into account the type, quantity, and / or - of the chip due to the detected speed. large the presence of blocking components is determined and then the non-comminuted blocking components are ejected after one or more reversals of the shaft.
- the controls of the shaft and counter shaft in such a way that one shaft comes to a standstill during the reversing process or reverses significantly more slowly than the other shaft. This counteracts the previously blocking components being thrown out.
- the blocking components are more likely to be carried along by the faster shaft and are thus carried to the same side of the comminution space.
- the method according to the invention can advantageously be carried out in such a way that the acceleration of the shaft is recorded in order to record the speed of the change in the load of the driven shaft which is equipped with shear elements.
- Hard, one-piece coarse parts e.g. Fragments of machined workpieces generate a high negative acceleration.
- Very dense tufts of chips cause a lower negative acceleration. The value is even lower for less dense tufts of chips.
- the rate of change in load can also be e.g. about the change in the torque of the shaft by means of strain gauges.
- the speed of the shaft deformation would vary. Vibration measuring devices are also conceivable, since a blockage by coarse parts would cause a higher vibration than dense tufts of chips.
- the method according to the invention can be carried out in such a way that, on the basis of the determined acceleration profile, the components causing the blockage are divided into at least two categories, the components being moved more or less frequently by reversing the shaft, depending on the applicable category, and either being crushed or thrown back uncrushed.
- a subdivision into categories allows for an optimized program flow for blocking components for each component type. For example, compacted tufts of chips that cause blockage are recognized as such due to the relatively low negative acceleration caused by them. This can be followed by a long, repeated reversing with the coarse part ejection element closed, as a result of which the compacted bundle of chips is to be crushed. At the end of the reversing process, dense remnants of clumps can still be present the coarse part ejection element to be opened are discharged.
- Blocking coarse parts form a further category. Coarse parts can be, for example, fractions of machined workpieces or screws. These coarse parts abruptly cause a high negative acceleration when blocked. Since such components cannot be crushed by the shear elements, a short reversing process is initiated when the coarse part ejection element is open in order to eject the coarse part as quickly as possible.
- the categories after increasing negative acceleration, the frequency of reversing from category to category decreasing with increasing negative acceleration.
- the method according to the invention can advantageously also be carried out in such a way that the speed change of the drive is measured in order to detect a negative shaft acceleration.
- the speed change of the drive is measured in order to detect a negative shaft acceleration.
- direct detection on the shaft is unnecessary.
- a detection on the shaft would only be realized with great effort. For example, a sensor would have to be protected from contamination by adhering or penetrating chip dust. An optical sensor would not be used due to the chips to be shredded.
- the method according to the invention can also be carried out in such a way that the rotational speed is set lower than the normal rotational speed during the reversing of the shaft. Lowering the speed when reversing prevents blocking components from being abruptly loosened and flung around in the shredding room. Instead, the blocking component has to be released carefully and carried over to the coarse part ejection element by reversing.
- a first device for shredding chips the above-mentioned object is arched with a horizontal shaft which is arranged in a shredding chamber and can be rotated in both directions by means of drive and control, is equipped with shear elements, with shear elements associated with this shaft and with a wave shape which is adapted to the wave shape
- Perforated screen bottom is equipped, solved in that a coarse part ejection element is attached to the walls of the comminution chamber lying parallel to the shaft axis and the counter shear elements are arranged in two rows on walls of the comminution chamber lying parallel to the shaft axis.
- a control for the coarse part ejection element is provided, the controls of the shaft and coarse part ejection element being networked with one another.
- a control for the coarse-part ejection element which detects the negative accelerations of the shaft, is provided for detecting the speed of the change in the load on the shaft and, depending on the respective negative acceleration, a variable number of reversing processes can be programmed when the coarse-part ejection element is closed and / or open.
- the first device according to the invention i.e. the horizontal single-shaft crusher enables the shredding process to run almost smoothly. There is a separation of hard parts and chips. Discharge of chips over the coarse part ejection element is largely avoided. Downtimes are reduced and wear on the shear elements is reduced.
- the device works automatically, which reduces the need for manpower.
- the device can be manufactured easily and inexpensively. It is possible to retrofit existing crushers accordingly or to use existing modules as far as possible when manufacturing new crushers. For example, as a coarse part ejection element a simple flap that can be opened to the outside is conceivable. But it can also be a door that can be moved sideways.
- the drive of a chip breaker is normally arranged outside the chip breaker, so that a measuring device can be accommodated there free of dust and easily maintained.
- the first device may be advantageous to design the first device according to the invention in such a way that one of the rows of shears is at the level of the shaft axis or lower, ie below the opening of the coarse part ejection element, and the other row of shears is arranged on the opposite wall above the shaft axis. If a component gets stuck between the lower row of shears and the shaft, a single reversal can loosen this component and move it directly to the opening in the wall, whereby it leaves the shredding room. At the On the opposite side, the row of scissors must be placed higher so that a blocking component that has to be transported to the coarse part ejection element can be transported more easily over the shaft.
- the first device according to the invention can be advantageous to design in such a way that the lower-lying shear row is the lower limit of the coarse part ejection element.
- a blocking component is already as close as possible to the coarse part ejection element. A brief reversal is sufficient to loosen this component and to remove it immediately.
- the first device according to the invention can advantageously be designed in such a way that the rows of shears are mounted on the walls with a slope towards the coarse part ejection element. Such a slope facilitates the transport of blocking components to and through the coarse part ejection element when reversing.
- a second device for comminuting chips which has a horizontal shaft arranged in a comminution space, rotatable in both directions by means of drive and control, and equipped with shear elements, and on an associated countershear element arranged on the same type and one matching the shaft and
- the counter-wave arched perforated sieve bottom is achieved in that a coarse-part ejection element that is to be opened is attached to at least one of the walls of the comminution chamber lying parallel to the shaft axis.
- a control for the coarse part ejection element which detects the negative accelerations of at least one of the shafts, is provided for detecting the speed of the change in the load on the driven shaft (s), the controls of the shaft, countershaft and coarse part ejection element being networked with one another; depending on the respective negative acceleration, a variable number of reversing processes can be programmed with the coarse part ejection element closed and / or open.
- the second device according to the invention ie the horizontal twin-shaft crusher, enables the shredding process to run smoothly.
- the first device according to the invention that is to say in the case of the single-shaft crusher, there is an almost pure separation of hard parts and chips, with discharge of chips over the coarse part ejection element being largely avoided. Downtimes are reduced and wear on the shear shafts is reduced.
- This device also works automatically and can be manufactured easily and inexpensively. It is possible to retrofit existing twin-shaft crusher accordingly or to use existing modules as far as possible when manufacturing new crusher.
- One or two coarse part ejection elements can be provided, for example in the form of flaps or sliding doors.
- the second device according to the invention i.e. to design the twin-shaft chip breaker in such a way that the negative accelerations of at least one of the shafts can be determined by recording measured values on the drive.
- the drive of a chip breaker is normally arranged outside the chip breaker, so that a measuring device can be accommodated there free of dust and easily maintained.
- the second device according to the invention i.e. to design the twin-shaft chip crusher in such a way that the shaft is mounted higher than the counter shaft and a coarse part ejection element is attached to the wall facing the counter shaft. Due to the increased mounting of the shaft, the previously blocking components are rather carried from the lower counter shaft to the coarse part ejection element. This reduces the number of reversals required, and a second coarse part ejection element can be dispensed with.
- both devices i.e. to design the single-shaft or two-shaft crusher in such a way that the device is set up with an angle of inclination about one or two axes. It can furthermore be advantageous that one or both inclination angles can be (are) individually adjusted.
- the ejection of coarse parts can be significantly simplified by inclining the device towards the coarse part ejection element.
- both devices can also be advantageous for both devices according to the invention to design the shear elements and / or counter shear elements differently on a shaft. So a wave or both shafts can be equipped with differently sharp (counter) shear elements.
- the sharper (counter) shear elements can be arranged in the areas of greater stress. In the case of an arrangement with a shaft axis slightly inclined in the direction of gravity, it makes sense, for example, to attach increasingly sharper (counter) shear elements from the higher shaft end to the lower shaft end.
- Both devices can advantageously be equipped with a drive in the form of an electric or hydraulic motor.
- both devices can provide a pulse pickup for measuring the rotational speed on the electric motor in order to detect the negative shaft acceleration.
- a rotor-shaped signal disc with proximity switch can be used as the pulse pickup.
- the coarse part ejection element is equipped with a sensor for detecting passing coarse parts.
- This can be an optical sensor. If a component passes the coarse part ejection element, the coarse part ejection element is closed immediately afterwards and the reversing process is ended.
- the devices according to the invention can advantageously be designed such that the coarse part ejection element is a flap that can be opened by means of pneumatics or hydraulics. Flaps operated in this way are already known and proven from other areas. An ejection element in the form of a flap is simple and inexpensive to manufacture. This embodiment is also robust enough to withstand the daily stress during the shredding process.

- chips are to be shredded from above, e.g. Metallic chips, placed in the shredding chamber 1, they are gripped by the rotating shear shaft 3, moved to the shear row 8, shredded between the shear elements 4 of the shear shaft 3 and the shear row 8 and carried to the perforated sieve bottom 14.
- the chips which are already small enough, fall through the perforated screen base 14. Larger chips are sheared between the shear shaft 3 and the perforated sieve bottom 14 and partly discharged through the perforated sieve bottom 14 or carried along by the shear shaft 3.
- the chips taken away are again crushed and transported back to the starting point. There, these chips meet new, still uncrushed chips and are transported with them again to the first row of shears 8 and again crushed.
- the chips to be shredded are mixed with coarse particles. This can be, for example, fragments of machined workpieces. Now such a part gets into the shredding chamber 1 between the shear shaft 3 and the shear row 8, the shear shaft 3 is blocked immediately. Compressed tufts of chips can also block the shear shaft 3, but the negative acceleration generated by the shear shaft 3 is lower than in the case of coarse parts.
- the negative acceleration of the shear shaft 3 is e.g. detected by speed measurements on the electric drive 5.
- the device parts for speed measurement are shown in Fig. 9.
- a programmed reversing and ejection program begins.
- the speed of rotation of the shear shaft 3 when reversing is significantly reduced compared to the normal speed of rotation.
- a reversing process of 20 reversing steps is set with the ejection flap 12 closed. This number should be chosen high enough so that the compressed tufts of chips can still be shredded. If the predetermined number of reversing steps is exceeded, the ejection flap 12 can be opened and a possibly still existing undrilled component can be discharged over the reversing shear shaft 3.
- FIGS. 2 and 3 each show a section BB through the single-shaft chip crusher from FIG. 1 with the chute 12 closed and with the chute open.

- FIGS. 4 and 5 show a top view and a section through a twin-shaft chip crusher with a comminution chamber 15 and an ejection chamber 16.
- a shear shaft 17 and a counter shear shaft 18 are arranged horizontally at the same level.
- the shafts 17, 18 are provided with a large number of shear elements 19, 19 'in the form of shear disks.
- the shear discs can be designed differently in terms of sharpness, hardness and shape.
- the outer edge of each shear disk 19, 19 ' is provided with at least one shear tooth 20 or the like.
- a perforated screen 21 is arranged below the two shafts 17, 18. This consists of a perforated screen bottom 22 which is concavely curved toward the underside of the shaft, a central web 23, 2 side walls 24, 25 and stiffeners. These individual parts are integrally connected to one another via weld seams 26, 27.

- the shafts 17, 18 are driven by an electric drive 30 and are provided with at least one control (not shown here).
- a first perforated screen side wall 24 is attached to the wall 28 in such a way that its top surface 31 lies above the shaft axes.
- the lower limit of the discharge which is formed by a head surface 33 of the wall 29, is designed with an inclination towards the discharge chamber 16.
- the edge of this head surface 33 facing the shredding space 15, ie the higher edge of the head surface 33, is located at the level of the shaft axes.
- the ejection flap 32 can be opened pneumatically or hydraulically towards the ejection chamber 16 via a lever device 34.
- control of the discharge flap 32 is also networked with the control of the shear shaft 17 in the case of the two-shaft chip crusher. Both controls are not shown here. It is also possibly a further controller, ie a controller of the counter shear shaft 18, can also be networked.
- chips are to be shredded from above, e.g. metallic chips, placed in the comminution space 15, these are from the shear discs 19, 19 'of the two rotating shafts, i.e. the shear shaft 17 and the counter shear shaft 18 are gripped, crushed between them and carried to the perforated screen bottom 22.
- the shear disks 19, 19 ' there is a shearing or cutting stress on the chips between them.
- the shear discs 19, 19 ' are arranged in such a way that the chips are subjected to cutting stress. The chips, which are already small enough, fall directly through the perforated screen bottom 22.
- the shafts 17, 18 may be blocked. Coarse parts can be both hard fragments and compacted tufts of chips.
- the negative acceleration of the shear shaft 17 and / or the counter shear shaft 18 is detected, for example, by speed measurements on the electric drive 30.
- the device parts for speed measurement are shown in Fig. 9.

- the shear shaft 17 could also be arranged closer to the discharge flap and the counter shear shaft 18 could be arranged further away.
- the reversing processes of the two shafts 17, 18 must be coordinated with one another in such a way that the coarse parts to be discharged are transported to the ejection flap 32 as quickly as possible. It can be provided that one of the two shafts or both shafts 17, 18 significantly reduce their rotational speed compared to the normal rotational speed during this program run. If there is now a hard, coarse fragment between the wall 28 and the shear shaft 17, when the same is reversed briefly, for example 5-6 times, the fragment is caught by the shear shaft 17 and transported to the counter shear shaft 18 via the same.
- the first perforated screen side wall 24 with a head surface 31 is attached to the wall 28 above the shear shaft and counter shear shaft axis.
- the coarse part transported to the counter shear shaft 18 is now gripped by the latter and conveyed to the discharge flap 32 by reversing.
- the coarse part falls into the ejection chamber 16 through this ejection flap 32.
- the ejection flap 32 is then closed again and the shafts 17, 18 resume their normal direction and speed of rotation.
- a reversing process of 20 reversing steps is set with the ejection flap 32 closed. This number should be chosen high enough that compacted tufts of chips can still be shredded. If the predetermined number of reversing steps is exceeded, the ejection flap 32 can be opened and a possibly still existing undrilled component can be discharged over the reversing shafts 17, 18.
- a further ejection flap is attached to the wall 28 opposite the ejection flap 32; the first perforated screen side wall 24 is to be designed accordingly shortened.
- coarse parts can be discharged through the transport via only one of the shafts 17 or 18. Precise coordination of the reversing movements of the two shafts can thus be dispensed with.
- FIG. 6 shows an embodiment of the twin-shaft chip breaker according to the invention which is slightly modified compared to FIGS. 4 and 5.
- the shear shaft which is further away from the discharge flap 32 (here: shear shaft 17), is arranged higher than the counter-shear shaft 18.

- FIGS. 7 and 8 show a twin-shaft chip crusher according to the invention in an inclined position
- the axis of rotation of the inclination is once parallel and once normal to the axes of rotation of the shafts 17, 18.
- Coarse part ejection chamber 16 is the discharge of coarse parts or compressed tufts of chips facilitated by the ejection flap 32.
- the material to be shredded is moved towards the lower ends of the shafts 17, 18.
- shear discs 19, 19 'with higher sharpness can be provided, which can in particular be difficult to shred tufts of chips.
- both inclinations can be combined and their extent varied. Such an inclined structure is also conceivable for single-shaft chip breakers.
- FIG. 9 shows an electric drive 5 or 30, on the motor shaft 35 of which a flat rotor 36 is attached.
- This rotor 36 has a plurality of rotor teeth 37 on its outer edge, which are arranged at a uniform distance from one another.
- the rotor 36 is not shown continuously in the figure.
- a light metal fan 38 is indicated above the rotor 36.

- This signal pickup 39 can be an optical sensor.
- the signal pick-up 39 detects the number of rotor teeth 37 moving past it.
- the controls of the shear shaft (s) 3 or 17, 18 and ejection flap (s) 12 or 32 are subjected to the respective negative accelerations of the motor shaft 35 via the signal pick-up 39 transmitted so that, depending on the acceleration category, a defined program runs, which includes reversing processes and possibly opening the ejection flap (s) 12 or 32.
