Definitions

  • the invention relates to a construction machine for processing of floor surfaces, with a milling drum, on the surface of a plurality of bit holders is arranged, wherein in a bit holder of the bit holder a chisel, in particular a round shank bit, is interchangeable added.
  • Such trained as a road milling machine construction machine is from the DE 39 03 482 A1 known.
  • road milling machines road surfaces can be milled off.
  • the chisels wear out continuously. If the chisels have reached a certain state of wear, they must be replaced. For this purpose, it is necessary that a worker goes into the area of the milling drum and drives out the chisels from the chisel holders there. When removing the chisel, the worker uses a special Austreibdornes and a hammer. This can lead to injuries.
  • the handling in the narrowed Fräswalzen Scheme is extremely cumbersome and requires great care to to minimize the risk of danger. After a chisel has been removed from its chisel holder, new unworn chisels must be inserted into the chisel holder. The exchange of the chisel is a very tedious and time-consuming job.
  • the road milling machine has a Fräswalzenkasten in which a milling drum is housed protected. This is equipped with a variety of chisels. To facilitate the replacement of worn chisels, a seat can be swiveled into the working area of the milling drum when the machine is stationary. There, the worker can then take a seat comfortably and carry out the tool change.
  • an exchange tool which automatically dismantles the worn bit and / or mounted an untapped bit in the bit holder holder of the bit holder.
  • the manual labor required to change the bits can be significantly reduced.
  • the fact that the change process is at least partially automated, this can also be done faster, so fewer machine downtime arise.
  • the health hazard and the physical strain on the operator are reduced.
  • the tool changing device has at least one tool changer, which is assigned to the individual bit holders or groups of bit holders by means of an actuating unit. It is also conceivable that all chisels or chisel holders together is assigned a single tool changer. This then dismantles or assembles the chisel at the same time.
  • the tool changers can also be connected to one another via a common control. For example, a machine operator can use this control to change individual chisels, groups of chisels or all chisels at the same time.
  • the design of the tool changing device can be such that the bit is positioned to the tool changer (see above b) and c)).
  • This can be done according to a possible variant of the invention such that the milling drum is coupled via a drive train with a drive motor of the construction machine, wherein the adjusting device has an auxiliary drive which can be coupled to the drive train, which rotates the milling drum in the raised state by a predetermined or selectable angle of rotation, wherein the torque of the auxiliary drive is higher than that Moment of inertia of the milling drum and the part of the drive train moving with the milling drum when the drive motor is switched off or decoupled.
  • you can take advantage of the given position pattern of the chisel and deposit it in a controller.
  • the setting unit and / or the adjusting device is equipped with a numerical control.
  • the tool design according to claim 1 is such that the setting unit positions the at least one tool changer relative to the milling drum. In this case, the tool changer and the milling drum are then brought into position to each other.
  • the tool changer (s) are fixedly arranged on the machine side.
  • the bits are then assigned to them as a result of a rotation of the milling drum.
  • the tool changer can be designed such that it engages the bit positively and / or non-positively and disassembled from the bit holder or mounted in this.
  • the tool change can be further automated if it is provided that the tool changing device conveys the dismantled bit directly or via a conveyor into a container or that the changing device is associated with a separating device, and that the singulator feeds bits from a storage unit of the tool changing device.
  • Optimal utilization of tool life can be achieved if it is provided that the milling drum is associated with a detection device, which continuously checks, at intervals or on default, the state of wear of the bit or a part of the bit or a single bit, and that the detection means Upon reaching a predetermined state of wear, a tool change initiated or signaled.
  • the wear detection can be designed, for example, such that at least one signal acquisition unit of the recognition device is assigned to at least one machine component directly or indirectly involved in the work process, that the signal acquisition unit detects an operating state of the machine component, and that the signal acquisition unit determines the state of wear via a signal processing arrangement ,
  • Fig. 1 is a rotary body of a road milling machine, namely a milling drum 10 is shown.
  • base parts 20 are arranged at a systematic spacing from one another.
  • the base parts 20 are connected to the roller surface 11, preferably welded.
  • the base parts 20 have a plug-in receptacle 21.
  • a Plug neck of a chisel holder 23 are used.
  • the chisel holder 23 is fixed to the base part 20 via a pressure screw 22.
  • the chisel holder 23 has a chisel holder 24, which in the present case is designed as a bore. In the bore, a bit 30, in this case a round shank bit, are used.
  • the bit 30 has a chisel head 31 to which a chisel tip 32 made of cemented carbide or a ceramic material is attached at the front.
  • a shaft 33 connects, on which a clamping sleeve 34 is mounted.
  • the clamping sleeve 34 is not axially displaceable, but rotatably connected in the circumferential direction with the shaft 33.
  • the chisel head 31 lies with the interposition of a wear protection disk 35 on a mating surface of the chisel holder 23.
  • Fig. 1 can recognize the bit holder 23 is associated with a tool changer 40 with a tool changer.
  • the tool changer 40 has a servomotor 43, which drives a transmission member 41.
  • the transmission member 41 is presently designed as a pull rod.
  • the transmission member 41 carries a Austreibdorn 42.
  • the Austreibdorn 42 can be introduced via the servo motor 43 in the bit holder 24. In this case, the mandrel penetrates into the bit receptacle 24 via the rear bore opening 25. He then meets the formed by the shaft 33 rear abutment surface.
  • the servo motor 43 pulls the Austreibdorn 42 into the bit holder 24.
  • the bit 30 together with its clamping sleeve 34 is pushed out of the bit receptacle 24.
  • the servomotor 43 pushes the Austreibdorn 42 back out of the bit receptacle 24.
  • the tool changer 40 can, for example, linearly by means of a, not shown in the drawing adjusting unit in the direction of the central longitudinal axis of the milling drum 10 be adjusted. It can then be gradually assigned to the individual bit holders 23 of the milling drum 10.
  • the servo motor 43 does not move alone a Austreibdorn 42, but several Austreibdorne 42 at the same time, so that a plurality of chisels 30 can be pushed out of their bit holders 23 with one adjusting operation.
  • the milling drum 10 can be rotated via an auxiliary drive of an adjusting device.
  • the auxiliary drive can be used when the milling drum 10 is lifted off the ground. Then it can be adjusted for tool change by means of the auxiliary drive.
  • the auxiliary drive is also assigned a control unit. This rotates the milling drum 10 according to a predetermined program sequence, so that the chisel 30 or a part of the chisel 30 can be successively aligned with the tool changer 40.
  • a tool changer 40 is shown which is used to mount an unworn bit 30 in the bit receptacle 24.
  • the tool changer 40 in turn has a servomotor 43, which adjusts the transmission member 41 linearly.
  • the transmission member 41 has a mounting bell 44. This is provided with a receptacle 45 in which the chisel 30 to be mounted is held with its chisel head 31.
  • the tool changer 40 is accordingly assigned to the bit holder 23 by means of an actuating unit. In this case, then the shaft 33 is opposite the hole entry into the bit holder 24. Subsequently, the servo motor 43 is activated. The shaft 33 is then inserted into the bit receptacle 24.
  • the in the Fig. 1 and 2 shown tool changer can be used individually or together on a road milling machine. If they are used together, then a fully automatic bit change can be performed.
