Definitions

  • the invention relates to a device for inserting washed roll towels into a mangle, which is preceded by a mangle inlet, under which a pit for hanging conveying of the roll towels is arranged upwards, a guide device for the roll towels being arranged in front of the mangle, the one surface or edge engaging with the respective roll towel.
  • Such a device is known from DD-A-55319.
  • This device has two sections, namely an insertion section in front of the actual ironer and a winding section which is connected downstream of the ironer with the interposition of a memory. Oversized towels should be guided in the area of the second section, while such guidance cannot be determined with regard to the insertion section of the device.
  • a certain extension of the roll towels in the longitudinal direction can be assumed if they are gripped by the ironer rollers and pulled over a fixed angle and a subordinate guide roller. There is therefore no stretching of the roll towel web in the transverse direction, i.e. no stretching. Devices that would cause a straight inlet are also not provided.
  • the guide device also includes a roller that should have a slightly curved surface or should be flatly curved. It may be that with such means a certain control of the edge course of a towel web in the winding area can be achieved; in no case can this remove the wrinkles that were previously lacking in the towel rail.
  • DE-A-2659739 relates to a device for the straight guidance of a plurality of single-surface, textile fabrics which run endlessly next to one another and which are already tightened laterally due to their endless circulation, so that it is important to counteract asymmetrical processing tensions and to achieve straight guidance .
  • a clamping beam is used, which can be changed in its inclined position as a whole via a first adjusting device.
  • Individual adjustment zones are arranged on the clamping beam, each of which is assigned to an endlessly revolving path. These adjustment zones can be changed in their inclined position independently of one another by a second adjustment device, which is supported on the tensioning beam.
  • the adjustment zones are designed as flat surfaces and can be provided with an automatic position control or control, which acts on the actuating devices of the individual adjustment zones in the sense of a linear guidance of the endless path in question, so that a fully automatic linear guidance is achieved.
  • the problem of lateral tightening of the treatment path does not arise here, because here an endlessly revolving treatment path is used from the outset, which has no tendency to give up this tightening.
  • a device for feeding relatively small items of laundry is described and illustrated in US Pat. No. 3,553,863, wherein this device can be designed in multiple lanes.
  • a curved, stationary transverse stretching sheet or spreading sheet with a curved or curved edge is used for each web.
  • a vacuum source is used which acts on the laundry items through an opening such that the laundry items are spread, that is to say tightened, in the transverse direction.
  • a force counteracting the pull-in force of the defect is exerted on the item of laundry, so that the shape of the spreading edge results in the transverse tightening.
  • spreading plates and vacuum application belong together, so this effect can only be achieved in the interaction of spreading plate and vacuum. It is not important that the small items of laundry run straight in. Such an effect is neither described nor conceivable for a person skilled in the art due to an expansion plate and the use of negative pressure.
  • the invention has for its object to provide a device of the type described above, with which it is possible to achieve both a straight edge and a laterally tightened entry of the roll towels into the ironer while maintaining the longitudinal extension.
  • the edge or surface is convexly curved and is provided on a pivotably mounted component, the pivot axis of which is arranged perpendicular to the plane defined by the curved edge or a generatrix of the curved surface, and in order to control the pivoting of the Edge or surface a button that detects an edge of the respective roll towel and an on the component articulated drive are provided.
  • the invention is based on the knowledge that the convexly curved spreading edge can itself be driven, so that this one component can then fulfill the double function of straight edge running in and lateral stretching.
  • it is advantageously possible, for example, to utilize a mangle width of approximately 3.5 m and to iron and roll up about 10 such roll towels next to one another, only one operator being required for the device.
  • the component which effects the straight inlet and the lateral tightening can be designed as a flat plate or a spherical roller. Other configurations are also conceivable.
  • the button that detects one edge of the respective roll towel can have a photocell or a microswitch, via which the pivoting of the component is then controlled in such a way that an edge-straight entry takes place in the area of the one monitored edge, so that this edge follows also aligns the other, unmonitored edge.
  • the drive for pivoting the component or the curved edge or surface can have an air cylinder or a stepper motor.
  • the roll towel is treated symmetrically to its central longitudinal axis.
  • the influence of the pivoting movements on the roll of towel is particularly great.
  • Adjustable stops can be provided to limit the pivotability of the components on both sides in order to be able to adapt and adjust the device in this way.
  • the mangle system 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 the fabric web 6 can thereby additionally be directed 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 left adjoining devices of the same design are only indicated 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, wherein it has 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 transverse 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.
  • the cam track 12 is indicated in its middle position in the gas-drawn position and in its two end positions in a dash-dotted position.
  • 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, d. H. can be a closed rotating surface or a partial rotating 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.
