Definitions

  • the invention relates to a floor laying device according to the preamble of patent claim 1 and a method according to the preamble of patent claim 6
  • hose pieces are arranged with their hose longitudinal axis transverse to the transport direction.
  • a tube alignment table is used in known, generic devices for the individual alignment of the tube pieces, which preferably consist of paper.
  • the piece of hose separated from a stack of pieces of hose in a piece of hose separation device is discharged onto an alignment unit with which the pieces of hose can be aligned belts running in the direction of transport.
  • the belts have the stops attached to the transport side. The stops are arranged at a distance from the machine cycle.
  • At least one conveyor element is arranged in the space between the belts, which can be designed as a belt and which is inclined at an angle to the direction of transport.
  • These funding elements usually have one speed increased compared to the transport speed, so that a difference in speed to the transport speed is generated.
  • the differential speed has a linear dependence on the transport speed. This applies to both the longitudinal and the transverse direction, based on the hose section.
  • a conveyor belt arranged on one side and vertically is generally provided, which takes over the limitation of the lateral positions of the tube pieces.
  • the hose element can be displaced relative to the transport device by means of the conveying elements. In this way the piece of hose is aligned.
  • the workpiece placed on the alignment device at cycle speed is now conveyed from the obliquely arranged, generally faster-running conveying elements to the front stops via the sliding friction that arises between the belts and the workpiece, until the tube piece lies against these stops. Since the stops are also spaced apart from one another in the transverse direction, the tube piece is also rotated about an axis that is perpendicular to the tube plane if necessary. If the piece of tubing is already in contact with a stop, it is rotated around this stop point until it is also in contact with another stop. In addition, there is a transverse alignment at the same time, which means that the piece of hose also runs against the side stop. In other words, alignments of the tube piece are carried out on the alignment unit
  • an orientation about an axis of rotation means that rotation takes place with an angle of rotation of less than 20 degrees, in particular less than 10 degrees and preferably less than 5 degrees.
  • the lateral alignment belt is also sometimes reached early. This means that the alignment process has already been completed satisfactorily, but the piece of hose has not yet reached the end of an alignment section. Since the sloping conveying elements still act on the piece of hose afterwards, this is still pressed against the stops. It can happen that the hose pieces are damaged, especially if they are made of very flexible material.
  • the object of the present invention is therefore a
  • To create floor laying device for the production of at least one floor provided hose pieces, which largely prevents damage to hose pieces during their alignment.
  • the alignment process can be influenced in such a way that, for example, the execution of the alignments is essentially ended when the tube piece reaches the end of the alignment section.
  • the easiest way to do this is to change or even control the differential speed.
  • This can influence the duration of the alignment process so that the load on the material has been as low as possible at the end of the alignment section.
  • the conveyor elements can be driven by their own drive or that a variably adjustable gear stage is provided between the main drive and conveyor elements. In particular in the case of conveying elements arranged with an inclination angle, it is nevertheless possible the alignments that have already ended still exert a force on the hose element.
  • the relative position of the conveying elements to the direction of transport can be changed, in particular controlled.
  • this can mean that the conveying elements can be adjusted vertically, in the transverse direction and / or with respect to the angle of inclination relative to the transport device, the tube piece being transported horizontally and in a direction which is essentially perpendicular to its longitudinal axis. If the vertical position can be changed, the conveying elements can be brought into a position below the transport device, so that the conveying elements come out of contact with the hose section and the hose section cannot be moved any further relative to the transport device. It is also conceivable that the entire conveyor elements can be displaced relative to the transport device and / or can be changed with regard to the angle of inclination.
  • the transverse alignment and / or the rotary alignment can be carried out by independent movements of the conveyor elements.
  • the independence of the movements accordingly allows the orientations transversely to the transport direction and / or about the axis of rotation to be independent of the alignment path, so that the start time and the end time of the orientations can be selected independently.

  • the actual position of each piece of hose is first detected and this is then, preferably individually, aligned by appropriately controlling the conveying elements and / or changing their position, as has already been described above.
  • the size of the deviations from the target position can be determined by means of the computing and control device.
  • control and computing device After the deviations have been determined, the control and computing device generates control commands which are directed to the conveying elements and / or their drive or actuators. This can be understood as controlling the alignment, wherein the generation of the control commands and the control of the conveying elements takes place in such a way that the tube piece has subsequently assumed the desired position within tolerance limits.
  • a point in time can be calculated with a computing and control device at which the differential speed can be reduced to or less than zero and / or the relative position of the conveying elements to the transport device can be changed such that the piece of hose rests relative to the transport device.
  • the action of the conveying elements on the hose section can thus be ended when the hose section should have reached the desired position within tolerance limits.
  • the achievement of the target position is not verified, but only calculated in advance. It is therefore not necessary to set up a complete control loop.
  • the floor-laying device comprises at least one sensor with which the actual position of the hose piece relative to the transport device can be detected.
  • a sensor can be a light scanner, a light barrier, a camera or any other optoelectronic component which, for example, converts a change in contrast into an electrical signal and makes it accessible to a computing and control device.
  • a camera can be advantageous since it is used to take an image of complete hose section can be recorded and the actual position of the hose section can be easily determined.
