Definitions

  • the present invention relates to a machine for the plane frame printing of textile products and the like, operatively controlled by an electronic apparatus for the control and adjustment of the speed of the belt and of the alignment thereof, both longitudinal and transverse, capable of ensuring a print with high precision and assured repeatability.
  • various type of printing devices are used for printing, in one or more colors, textile products, and are differentiated in the methodology and in the devices used according to the quantity and the quality of the finished product.
  • Said machines which, due to the plurality of the stations, allow elevated production, do not however ensure the perfect execution of the product, also due to the systems used, which are composed of mechanical or hydraulic grippers which grasp the belt on the sides and move it into alignment with reference to external stroke limiters.
  • These systems can give rise to remarkable disadvantages, since these grippers do not ensure a perfect grasp due to slippage and most of all, even with very small errors, cannot ensure correct positioning of the belt after a high number of rotations.
  • FR-A-24 53 096 is a machine for the plane frame printing of textile products as defined in the precharacterizing part of claim 1.
  • the main aim of the present invention is to provide a rotating-belt printing machine structured so as to ensure a high quality and repeatable printing action and capable of ensuring a constant translatory speed of the belt, monitoring, at the same time, its perfect alignment, both longitudinally and transversely, during the passage under the printing station.
  • Another object of the invention is to provide a printing machine with plane frames and with a rotating belt, capable of allowing high productivity, by virtue of the possibility of increasing the translatory speed of the belt and rendering automatic, most of those services which usually reduce, in known systems, the printing operations, these possibilities being allowed by the fact that the printing station (or stations) are kept in a fixed position.
  • a further object of the invention is to provide a machine of the type described above, structured so that, by virtue of the use of a particular reading system, rigidly coupled to the belt, combined with a system for detecting the fixed pitch at the printing station, it allows to calculate, by means of a calculator, the perfect takeup of a pitch even if the latter is not a submultiple of the extension of the belt.
  • Still another object of the invention is to provide a printing machine with very small overall dimensions, in practice equal to half, with respect to the conventional fixed table, and such as to save the operator the need to move along the table as required in the case of a fixed and very long table.
  • Not least object is to provide means for laying the fabric on the belt such as to avoid any danger of uncoupling from the belt, during the rotations thereof around the rollers.
  • the machine comprises a conveyor belt 1, arranged in a closed loop formation around two end rollers 2 and 3: the roller 2 is provided as a traction roller for the belt 1 along the arrow A and for this purpose a direct-current or similar motor (not illustrated) is associated with its axis, while the roller 3 constitutes a transmission and tensioning roller for the belt using known and not illustrated means.
  • the function of the driving roller 2 is only to cause rotation of the endless belt in order to transfer the textile product to be printed, fed on the belt in a known manner by means of end rollers 4, below the printing station 5, and then to transfer the same to the end of the upper portion of said belt, where it can be extracted by means of rollers 3a, or to return it to the feed area, following the lower portion of the belt, where it can be extracted by means of the rollers 4a, or even perform a plurality of rotations for printing in multiple colors.
  • a printing station 5 is positioned fixed above the belt 1, and is composed of two parallel shoulders 6-6a (Figs. 4 and 5), supported by two opposite crosspieces 7-7a rigidly coupled to the sides of the machine; within these shoulders 6,6a, a support 8 for the doctor blade or spatula 9 is advantageously slideably mounted by means of a kinematic transmission and a motor 10.
  • the doctor blade 9 is magnetically coupled to the supporting bar 8 and is subjected to a constant pressure on the part of suitably spaced pneumatic pistons 11.
  • the extent of the translatory motion of the support 8 along the shoulders 6-6a is variable and depends on the dimensions of the printing frame, and the setting of the extent of the translatory motion is expediently performed by electronically memorizing the actual position of the doctor blade, moving it both by means of buttons for actuating the motor 10, or manually or even by detecting the dimensions of the print frame by means of sensors arranged on the doctor blade-bearing bar 9.
  • the present invention provides, in association with the belt 1, a device for the continuous measurement of the motion of the belt, based on a known detection system, precisely described in FR-A-2,560,096, which claims priority from the Italian patent application no. 23830 A/83 filed on 22nd November 1983.
  • the device is rigidly coupled to said belt so as to ensure the perfect registering of the textile product below the printing station and, simultaneously ensure the perfect alignment of the belt both longitudinally and transversely.
  • Said device for detecting and adjusting the traction speed of the belt on the part of said driving roller 2 is substantially composed, according to the present invention, of at least one band 12 (Fig. 2-3), advantageously constituted by a continuous steel band, rigidly coupled to the peripheral edge of the belt 1, for example by rivets 13, and extending in length so as to affect the entire length of the belt 1.
  • band 12 advantageously constituted by a continuous steel band, rigidly coupled to the peripheral edge of the belt 1, for example by rivets 13, and extending in length so as to affect the entire length of the belt 1.
  • a series of holes 14 are provided, which holes are advantageously substantially rectangular in shape, substantially equally spaced apart from each other, and arranged in one or more rows.
  • the holes 14 are intended to remain in constant engagement with the teeth of underlying toothed wheels, preferably idly mounted on their axes and indicated by the reference numerals 15-15a-15b in Figs. 1 and 4; said toothed wheels are arranged below the printing station 5 so as to keep the belt constantly in tension and aligned in the print area, regardless of the eventual oscillations and/or fluctuations of the remaining part of said belt.
  • a rotary transducer On the axis of one of said toothed wheels, for example the wheel 15, a rotary transducer is rotatively coupled, substantially an encoder of the incremental type which is of a known type and thus not illustrated, (as already mentioned), the purpose of which is to supply electric output signals corresponding to the rotation of said gearwheel 15 rigidly coupled to the band 12, which signals, by means of control elements operatively associated with said encoder and with said motor for operating said roller 2, are capable of providing electric output control signals adapted for driving said motor which operates the traction roller 2 of the belt 1.
  • the reading and measurement system rigidly coupled to the belt, never uncouples from the system for detecting the already preset fixed pitch for the print station, it is possible to calculate with ease, by means of a calculator, the perfect resumption of a printing pitch both in the case in which the pitch is a perfect submultiple of the extension of the belt and also in the case of a pitch equal to any submultiple of the extension of said belt; in other words, the resumption of the pitch can be performed regardless of the dimension (extension) of said pitch.
  • the above described machine is furthermore completed by the known heating systems 16 for drying the fabric, which is carried out by conveying warm air on the upper part of the belt, by belt washing devices 17, arranged below the return portion of said belt and by usual devices for the laying and removal of the textile product by means of the above mentioned rollers 4a and, respectively, 3a.
  • the computerized machine according to the invention is adapted for printing by means of a printing station with automatic operation as briefly described above, but can be advantageously used also with printing stations of the conventional type.
  • the laying of the fabric gives rise to particular problems due to the fact that the fabric, during the motion of the belt around the end rollers 2 and 3, tends to uncouple from said belt, thus compromising the printing precision in the subsequent phases.
  • the fabric is subject to a tension which causes the uncoupling thereof from the layer of adhesive, since the deformation by stretching of the upper portion of the belt with respect to its original length and the consequent elongation of the upper part of adhesive causes the fabric, already pre-stretched, to tend to exceed its remaining percentage of elongation and therefore, by becoming rigid, that is without elasticity, to cause its uncoupling from said adhesive.
  • the present invention provides, as schematically illustrated in Fig. 6, a different initial positioning of the fabric on the belt, already provided with adhesive.
  • the fabric 17, which unrolls from a free roll 18 (Fig. 6) is guided on a motorized unwinding cylinder 19 and then, passing through deviation rollers, around a speed adjustment roll or roller 20 to which a potentiometer (not illustrated) is applied for the adjustment of the speed of said roller 20; during unwinding, the fabric is subjected to pretensioning, adjusted according to the type of fabric, and is then caused to adhere to the belt 1 by means of a usual presser roller 21.
  • the line of contact between the fabric and the belt is selected, according to the present invention, in a rearward position with respect to the start of the plane region of the belt 1 and precisely in a position which is angularly rearwardly offset by an angle "i" with respect to the start line of the upper plane portion of the belt (see figure 6).
  • the shift of the initial laying position in the curved region of the belt, while allowing application of the fabric with the provided tension in order to ensure its planarity on the belt, allows the performance of the glueing of the fabric to a part of adhesive already subject to elongation since it is already arranged on the curved part of the belt; accordingly, the fabric, already tensioned on the curved region of the belt, is subject to a compression of its fibers when it reaches the plane part of the belt, which compression is allowed by the residual degree of elasticity remaining after the initial tensioning; accordingly, the fabric, when it reaches the curved part of the cylinders 2 and 3, is again in its elastic range without being subjected to stiffenings such as to cause its uncoupling from the adhesive.
  • This method of laying on the curved part of the motor cylinder 2 is thus capable of preventing the uncoupling and the shifting of the fabric from the conveyor belt, even after many rotations of said belt.
