Definitions

  • the present invention essentially relates to a process for the continuous control of an endless strip, in particular a strip intended to entrain a fabric which must receive successive impressions, the offset of which must be zero or reduced to a minimum in order to thus preserve the aesthetics of the printed fabric.
  • This invention also relates to a machine for continuously monitoring an endless belt for the implementation of this method.
  • textile printing machines generally comprise an endless sheet or band surrounding two cylinders, one of which is rotated and above which cylinders or flat frames are arranged. successive printing capable of printing patterns of different colors on a strip of fabric entrained by the strip and sandwiched between this strip and the printing cylinders.
  • the sheet or the endless strip generally has a sandwich structure of several more or less thick layers of elastomeric material, of fabric, etc., capable of allowing the printing of the fabric resting on the strip by compression of the cylinders or flat frames. printing on the fabric.
  • the endless belt is obviously driven at constant speed, but the speed of movement of the band remains irregular despite everything due to local-possible defects or variations in the internal structure of this band, these defects or variations in structure giving the band somewhat variable elasticity.
  • Such cropping can reach a few tenths of a millimeter, which is detrimental to the appearance of the fabric. Indeed, one cannot tolerate a cropping which is higher than approximately one tenth of a millimeter.
  • the present invention provides a method and a machine for continuously monitoring an endless belt, which make it possible to guarantee zero cropping or reduced to an acceptable minimum when said belt is fitted to a fabric printing machine.
  • the subject of the invention is a process for the continuous control of an endless belt, for example intended to drive a fabric which must receive successive impressions, the cropping of which must be zero or reduced to a minimum, and according to which performs on the strip a succession of marks detected by a device for measuring strip advance errors, characterized in that it consists in depositing periodically and simultaneously on a stretched strand of the strip driven at constant speed, two spaced drops dye, such as for example ink, coming respectively from an upstream injection system and from a downstream injection system so as to obtain on the stretched strand of the strip successive groups of two adjacent drops, to measure continuously and downstream of the downstream injection system the difference between these two adjacent drops, to memorize each measured value of difference between the two adjacent drops, to calculate the average of the different measured differences and to make the difference between the difference currently measured and said average, which allows very precise evaluation of the cropping which would be obtained on a fabric entrained and printed using said strip.
  • the invention also relates to a process for the continuous control of an endless strip, for example intended to entrain a fabric which must receive successive impressions, the cropping of which must be zero or reduced to a minimum, and according to which a succession of marks detected by a device for measuring errors in advance of said strip, characterized in that periodically a drop of dye is deposited on the stretched side of the strip, such as for example ink from a single injection system so as to obtain on the stretched strand of the strip a succession of drops, and we measure continuously and downstream of the injection system, the differences between the successive drops to determine the average value of the position of the neutral fiber in the strip.
  • a drop of dye is deposited on the stretched side of the strip, such as for example ink from a single injection system so as to obtain on the stretched strand of the strip a succession of drops, and we measure continuously and downstream of the injection system, the differences between the successive drops to determine the average value of the position of the neutral fiber in the strip.
  • the position of the neutral fiber in the strip is substantially constant, it will therefore be certain that the running speed of the said strip will also be substantially constant and that consequently this strip will be suitable for printing a fabric without defects in framing. It should also be added that the precise knowledge of the position of the neutral fiber will allow the operator of the textile printing machine to preset the said machine so as to obtain the required printing precision.
  • the invention also relates to a machine for implementing the method meeting one or the other of the above characteristics, this machine being of the type comprising a frame supporting two cylinders receiving an endless belt to be checked and whose l one is rotated by a motor to which an encoder is mechanically connected, characterized in that said frame carries, above the strip, at least one dye injection system and at least one camera connected to a computer, while the encoder is electrically connected to said injection system and to said camera.
  • this machine is mounted rolling, meshing or the like a first gantry located on the side of the cylinder driven by the engine and supporting a first dye injection system as well as two cameras, and a second gantry located on the side of the other cylinder and supporting a second dye injection system.
  • the other aforementioned cylinder is removably mounted on a rolling carriage or also meshing on the frame and capable of passing under the two aforementioned gantries.
  • the cylinder driven by the motor is removably mounted on a support fixed to the frame and carrying the aforementioned motor and encoder.
  • the machine according to this invention is further characterized in that it is functionally associated with a fabric printing machine or the like to regulate the speed thereof.
  • the printing machine itself may include all the means according to this invention for carrying out continuous control of the current speed of travel of the endless strip which drives the fabric to print it.
  • FIG. 1 is a schematic perspective view of an endless belt control machine, in accordance with the principles of the invention.
  • Figure 2 is a diagram illustrating a first mode of operation of this machine.
  • Figure 3 is a diagram illustrating a second mode of operation of the machine.
  • Figure 4 is a partial plan view of the endless belt as it appears on the computer screen, with cropping and neutral fiber values measured for a certain length of band.
  • Band B if its control proves satisfactory, may be transferred to a printing machine (not shown), or else, without departing from the scope of the invention, the printing machine may be integrated into the printing machine. control visible in Figure 1.

  • the rear cylinder 3 is removably mounted on a self-propelled carriage 4 meshing with a rack 5 secured to the frame 1.
  • the front cylinder 2 is removably mounted on a support 6 fixed, by any suitable means, to the frame 1 of the machine. On this fixed support is mounted a motor 7 for driving the cylinder 2 in rotation, and an encoder 8 is mechanically connected to the shaft of the motor 7.

  • a computer 0 shown diagrammatically in FIGS. 2 and 3 and connected to the video cameras 12 and 13 allows the calculation of the cropping and the position of the neutral fiber of band B, as will be described in detail below.
  • the two gantries 14 and 15 are moved back on the frame 1 towards the right end of this figure, and the self-propelled carriage 4 supporting the rear cylinder 3 is advanced on the frame 1, passing under the gantries 14 and 15, towards and relatively near support 6 bearing the motorized cylinder 2.
  • This motorized cylinder 2 is detached, by one of its ends from the support 6, and the endless band B to be checked is threaded (shown in dotted lines on the left side of FIG. 1) on the cylinder 2 which is then put back on its support 6.
  • a traveling crane, hoist or the like shown diagrammatically at 18, is used to reassemble the rear cylinder 3 (or 3a) threaded into the band B, on the self-propelled carriage 4 located very close to the support 6 carrying the front cylinder 2.
  • the strip B is thus in place, that is to say surrounding the cylinders 2 and 3, the two gantries 14 and 15 are brought to the left in FIG. 1, in the position visible in this figure by passing over the strip B.
  • the carriage 4 is brought to the right of FIG. 1 to take the position visible in this figure, it being understood that the strip B will, thanks to the carriage 4, be tensioned.
  • the tension of the strip will be adjusted by means of jacks (not shown) by an operator who will control the prescribed value of tension on indicators marked at 19 in FIG. 1.
  • the system is originally designed to give 900,000 points from the encoder 8 per revolution of the drive cylinder 2.
  • the encoder 8 gives the order to the injection systems 10 and 11 for each movement P i of the strip B, to simultaneously print a drop a, b on the sheet, after which the cropping caused by the irregularities of the strip will be controlled by the camera 12, downstream of the injection system 11.
  • the differences X i between two drops a, b are measured by the camera 12 connected to the computer 0 in which each difference value between two drops is stored.
  • a drop a i of the injection system 10 should be located exactly at the same place on the strip B as the drop b i + m emanating from the injection system 11, m being equal to the number of intervals L of 1 meter between the systems 10 and 11.
