Definitions

  • the invention relates to a trough lack according to the preamble of claim 1.
  • Trough ironers have at least one curved, flexible Lack trough, which is the lower half of a drivable Ironer is assigned.
  • the respective shortage is heated by a flowing heat transfer medium, such as Example steam.
  • the heat transfer medium is under pressure the shortage trough passed through.
  • the shortage trough is available over a double walled structure, whereby flow channels for the heat transfer medium can be formed in the ironer.
  • the walls of the double-walled trough are formed made of relatively thin, flexible sheets.
  • the walls or sheets are welded together, on the one hand through welds on the outer edge and the other on theirs Surfaces through a grid of welds. Between Weld spots are caused by a deformation (expansion) of the outer wall the flow channels for heating the Defect well serving heat transfer medium is formed.
  • weld spots are for area-wise connection of the walls or sheets as Weld spots formed. These weld spots only have about a limited resilience because they only have one can have a relatively small area. Large welding spots would cause deformation of those facing the ironer lead inner flat surface of the lack well, including the Deficiency quality suffers if you do not follow this deformation welding by mechanical finishing of the inside the lack trough eliminated.
  • the object of the invention is based on the foregoing to create a trough lack where the walls are connected by heavy-duty welds, which the Do not or not significantly impair the inner surface (flattened surface).
  • a lack of troughs to solve this task has the features of claim 1. Due to the formation of welds circumferential, in particular multiple circumferential welds will increase the effective welding area achieved against welding points, preferably by the circular circumferential welds during the welding process Accumulation of energy is avoided, which affects the inner surface of the Wall of the mangle trough (flat surface) not or not significantly impaired. It will be one high-strength connection of the walls of the lack trough to everyone Welding point reached, which also higher internal pressures of the Deficiency trough reliably withstands, without it being a noteworthy or expensive post-processing of the flattening surface is required.
  • the weld seam of the welds is preferably endless.
  • the weld seam of the respective welding point ends approximately the same place from which it starts.
  • the weld seam of the each welding point thus has a closed one Path that is preferably circular and / or spiral.
  • Such an endless weld with a closed seam is particularly resilient because there are no open weld ends are present that encourage the weld to be torn open could.
  • the Weld of the welds preferably each weld, several times, for example three times, completely.
  • the circulations of the weld seam are included dimensioned so that the weld seam sections of the individual Circuits do not overlap and / or touch. Just on The weld seam sections intersect at least one crossing point different rounds so that the end of Weld seam can get back to the beginning of the same Formation of a closed, endless weld.
  • the weld seam sections of the individual Only cut circulation, but not overlay or touch there will be an accumulation of energy at each Avoided weld.
  • the invention trained welds not the flattened surface or not significantly affect, so that no post-processing requires or at least no significant post-processing is required.
  • all orbits around a common center It changes the radius of at least part of a revolution Weld continuously so that it welds at least partially revolves in a spiral. This can cause a Coverage or overlap of the weld seam sections of different Circulations are prevented, so that by the individual Circulations formed annular parts of the welds are at least partially, preferably largely adjacent to one another and in some cases run parallel to each other.
  • Fig. 1 shows an example of a trough lack according to the Invention.

  • the trough lack has also via an underframe 15, which the two troughs 10 and 11 carries.
  • the invention is also suitable for Trough ironers, the more than two ironer troughs 10, 11 and ironer rollers 12, 13 or only through a single defect trough 10 and ironing roller 12 have. In the latter case the trough lack over no bridge 14.
  • the two in the exemplary embodiment shown are preferably the same trained ironing rollers 12 and 13 have a cylindrical Shape up. They are each about a central axis of rotation 16 and 17 continuously rotatable.
  • the outer cylinder jacket each ironer roller 12 and 13 is not with one in the figures provided wrapping shown.
  • the deficiency troughs 10 and 11, which are generally of the same design have an approximately semicircular cross section.
  • the Deficiency troughs 10 and 11 essentially surround the lower half of each ironer roller 12 and 13 (Fig. 1 and 2).
  • a curved inside of each trough 10 and 11 forms one smooth plate surface 18 and 19.
  • each trough 10 and 11 and the winding formed lateral surface of each ironing roller 12 and 13 are in the Figures not shown textile objects, in particular Items of laundry that can be moved through the trough.
  • To is between each trough 10 or 11 and the associated ironer roller 12 and 13 in the figures better visibility in an enlarged width, approximately semicircular nip 39. Wherever between the respective mangle roller 12 or 13 and the mangle trough 10 or 11 there is no laundry item at the moment elastic winding of the ironer roller 12 or 13 on the smooth Flat surface 18 and 19 of the respective trough 10 and 11.

  • the walls of the lack troughs 10 and 11 are made thin, elastic plates or sheets formed.
  • the plates or sheets are made of steel, preferably stainless steel, especially stainless steel.
  • Through the double-walled design of the troughs 10 and 11 are in Inside the same cavities.
  • Through the cavities of the Lack troughs 10 and 11 is a pressurized heat transfer medium can be passed through.
  • the heat transfer medium is used for Heating of the mangle troughs 10 and 11. These are a heated fluid, especially steam. Connections to Feeding the heat transfer medium to the mangle troughs 10 and 11 and to discharge the heat transfer medium are for reasons of simplification not shown in the figures.
  • the mostly spaced, curved sheets for the formation of the shortages 10 and 11 are in the here shown trough lack of different thickness.
  • inner sheet 20 formed thicker than an outer sheet 21.
  • the sheet thicknesses for the thicker, inner sheet 20 can range between 3 mm and 6 mm.

  • the thickness ratio between the inner sheet 20 and the outer sheet 21 is in the range of 2 to 3.5. It is also conceivable, the inner and outer sheets 20, 21 with about to be of the same thickness.
  • the sheets 20 and 21 then have about thicknesses in the range between 2 mm and 5 mm, in particular 3 mm to 4 mm.
  • Both sheets 20 and 21 to form the respective trough 10 and 11 are connected together at their edges, preferably welded, in particular by Laser welding. As a result, the cavities 22 and 23 are between the sheets 20 and 21 of each trough 10, 11 fluid-tight.
  • the Sheets 20, 21 of each trough 10 and 11 are also together connected by on the area in particular the respective outer sheet 21 evenly distributed in a grid Welding points 24.
  • the welding points 24 are in the exemplary embodiment shown all trained equally. Through the Welds 24 are the sheets 20 and 21 of the troughs 10 and 11 connected to each other in some areas.
  • the welds 24 are in several parallel rows the same distances in a row.
  • the Welds 24 of adjacent rows are offset from one another, and preferably by half the distance between two successive ones Welds 24 in a row. Thereby are the welds 24 of adjacent rows on a gap.
  • the Distances between adjacent, preferably horizontal, rows are like this chosen that the distances between adjacent welds 24 in of the respective row are roughly the same size as the diagonal Distances of the welds 24 lying on the gap between them Rows (Fig. 3).
  • the areas of the outer area surrounding the welds 24 Sheet 21 of each trough 10 and 11 are from the inner sheet 20th spaced. This can only be achieved through hydraulic deformation of the outer sheet 21.
