Definitions

  • the invention relates to a method and a device for straight-edged and smooth introduction of long webs of fabric, in particular a roller towels, angel in a M, wherein the fabric of the lack is supplied positionally aligned along one of the two edges and tightened in the other transversely to the conveying direction.
  • the device for carrying out the method has a defect, which is preceded by a defect inlet, under which a pit for hanging conveying of the material web is arranged upwards.
  • Each mangle has a mangle inlet, which can either be designed as a stationary, essentially horizontally extending table, or it can consist of a short but possibly relatively wide rotating conveyor belt corresponding to the working width of the mangle. As is known, there is a pit under the inlet of the mangle if the mangle is set up for processing long strips of fabric, especially roll towels, as are used in particular in the catering trade.
  • the washing and ironing process of these roll towels is as follows.
  • the roll towels have a length of about 40 m and a width of about 30 cm.
  • the dirty towel roll is first unwound or meandered with an automatic unwinder folded. Then each towel is tied one or more times in this position in the middle or at both ends, ie wrapped and tied with a twine or the like.
  • the bundled towel roll then has a length of approx. 1 m. It is washed, dewatered and shaken in this bundled form. Only in this bundled form, because of their considerable length, several of the towel rolls can be washed in a washing machine and separated from one another after the washing process. After shaking, the bundled towel rolls usually still have up to 50% residual moisture of their initial weight.
  • one end of the towel roll is gripped and held in place while the rest of the cut bundle is thrown into the pit in front of the mangle, so that the towel is hanging vertically for a certain distance.
  • the free end of the towel roll is then fed to the mangle via the mangle inlet, where the mangle rollers grip the towel and pull the mangle itself through the mangle. So that the roll towel ord when used later in the automatic towel dispenser runs properly, it is necessary that it runs properly over its entire length of about 40 m in the ironer. So far, the entry into the shortage of operators has been monitored, and five towels can be monitored by one person using a pit. If, for example, ten roll towels are passed through a defect at the same time, two operators are already required at the defect inlet.
  • the aim of the invention is to avoid the disadvantages of the known methods and devices and to achieve an edge-correct infeed of the fabric web with less effort, in particular for operators.
  • Another purpose of the invention is to ensure that the fabric web not only runs straight, but also laterally streamlined into the ironer.
  • the first-mentioned purpose is achieved according to the invention in that the material web is guided over an edge or surface before the entry into the ironer, the part of which engaging with the material web pivots about an axis arranged at right angles to it, depending on the respective position of the material web becomes.
  • an edge-correct running-in of the fabric web is obtained practically automatically, because by correspondingly pivoting the edge or surface, ie by changing the position of the edge or surface relative to the fabric web, a necessary lateral displacement of the fabric web during the running-in is required can be achieved.
  • the edge or surface is pivoted depending on the determination of the position of a side edge of the fabric.
  • the said edge or surface is curved or curved, because in this case, in addition to the directivity, a lateral streaking of the fabric web is also achieved.
  • the ironer 1 has two drums 2, which are heated and over which the fabric webs are guided in a known manner, the residual moisture being removed from the fabric web.
  • the fabric panels are pressed at the same time, so that an ironing effect occurs.
  • the ironer inlet 3 In front of the first drum 2 of the ironer 1 is the ironer inlet 3, which is designed as a rotating conveyor belt 4. Immediately in front of the ironer inlet 3 is a device 5 according to an embodiment of the invention, via which the material webs 6 are guided in an appropriate number depending on the width of the ironer 1.
  • a roller 8 extending across the entire working width can be arranged, which is equipped with a plurality of radially projecting striking arms 9, which are set in a relatively slow rotation, so that in addition the fabric web 6 can thereby be straightened during its vertical transport .
  • the towel winder 10 Behind the rearmost drum 2 of the ironer 1 there is the towel winder 10, where the individual material webs 6 or towels are wound up in the form of rolls 11.
  • the fabric or towels 6 have a width of about 30 cm and a length of 40 m.
  • One end of such a towel is held in place while the towel is thrown down into the pit 7. With the end held, the fabric web 6 is then fed to the drum 2 via the mangle inlet 3.
  • the device 5 As soon as the front end of the fabric web 6 is gripped by the ironer 1, the remaining alignment, guiding and smoothing work is carried out by the device 5, so that a single operator is sufficient for, for example, ten roll towels in the area of an ironer 1.
  • the device 5 has a curved path 12 in the form of a curved edge, which has the shape shown in FIG. 2.
  • This cam track 12 is pivoted about a vertical axis 13 and provided with a drive.
  • FIG. 2 and 3 show details of the device 5, specifically in plan view according to arrow 14 in FIG. 1 and only in sections, only one curved path or curved surface 12 as a whole, that is to say for a fabric web 6, being shown, while the one on the right - And on the left-hand, identically designed devices are only cut off.
  • the cam track 12 consists of a thin metal plate (FIG. 3) and has the curved shape shown in FIG. 2, which can also be modified. In the illustrated embodiment, the cam track 12 has the highest elevation in the middle, so that a convex edge engages with the fabric web 6.
  • the cam track 12 is mounted on a frame 14 so as to be pivotable about the vertical axis 13, it having a lever arm 15 firmly connected to it, at the end of which, for example, an air cylinder 16 is articulated with its bearing 17 on the piston rod side.
  • the housing of the air cylinder 16 is supported on the rest of the fixedly arranged bearing 18. It can be seen that the cam track 12 is pivoted about the axis 13, to one side or the other, depending on whether the air cylinder 16 is extended or retracted.
  • the air cylinder is supplied with the necessary air via a control device, but this is not shown for the sake of simplicity.
  • the cam track 12 has approximately the width of a fabric web 6.
  • a photocell 19 which works according to the reflection principle, is arranged as a button for the straight inlet. It goes without saying that an air cylinder 16 and a photocell 19 belong to each cam track 12. If the photocell 19 is shaded by the fabric web or its one edge when the fabric web 6 is inserted, then the air cylinder 16 is actuated in such a way that the cam web 12 is transversely pivoted or pivoted about the axis 13 in such a way that the fabric web 6 suffers a lateral force component. which leads them away from the photocell 19.
  • the fabric web 6 is tightened transversely to the conveying direction.
  • Adjustable stops 20 and 21 can be provided to limit the pivotability of the cam track 12 to the right and left. In order to better illustrate the extent of the pivotability on both sides, the Curved track 12 in the drawn position in its middle position and in dash-dot position in its two end positions.
  • an edge-correct run-in and a lateral streaking or lateral tightening of the fabric web 6 are obtained simultaneously using a single pivotable component, the edge 12 of which engages with the fabric web 6 is convexly curved in the direction of the fabric web 6.
  • the corresponding component over which the fabric web 6 runs is provided in the form of a component which in turn can be pivoted and which has a spherical or curved rotating surface which engages with the fabric web, which is a complete, ie can be a closed rotation surface or a partial ground surface.
  • this component it is also possible to form this component as a roller with a spherical outer surface, in which case suitable means are provided to create resistance to rotation of the roller, for example in the form of a friction brake or the like.
  • the embodiment shown in the drawing enables the fabric web 6 to be run in with correct edging and lateral tightening with a single pivotable component.
  • a separate component for example known by means of a per se fixedly arranged usstreifers A, the bestitz in a direction against the material web convexly curved Ausstreifkante or Ausstreif Structure.
  • a stationary component can be arranged in front of or behind the straight guide device, but expediently in front of this device.
  • the edge or surface engaging with the fabric web 6 on the pivotable component of the straight guide device need not be spherical or curved. Rather, in such a case, it is sufficient if this edge or surface is straight. In this case, too, a lateral displacement of the fabric web 6 is brought about by correspondingly pivoting the component having this edge or surface. As before, the pivoting is appropriately controlled depending on the position of a side edge of the fabric web 6.
  • the pivotable component of the straight guide device can be a plate with a straight edge, a component with a closed rotating surface or with a partial rotating surface, or a cylindrical roller, in which case no means need be provided to provide resistance to rotation of the roller to accomplish.
