Definitions
- the invention relates to an ironing machine according to the preamble of patent claim 1, each having one or more upper and lower molds which are arranged such that they can be pressed against one another and have an ironing surface on their mutually facing sides, at least one, preferably each the upper and lower molds are assigned at least two clamping bars that can be moved to the ironing surface with an elastically stretchable cover attached between them.
- Such an ironing machine is known from EP-0 253 048.
- the ironing machine described there has an upper plate and a lower plate which are one above the other and perpendicular to one another, i.e. are movable towards each other.
- the top plate and the bottom plate are each assigned a stretching frame provided with a stretchable cover.
- the two clamping frames lie before the start of the ironing with an unstretched cover approximately at the height of the ironing surface, which is formed by the mutually facing side surfaces of the top and bottom plates.
- each of the tenter frames, between the covers of which the material to be ironed, for example a pair of pants is movably guided on a vertical guide.
- the ironing process is carried out in the following way: A pair of pants is placed on the cover of the tensioning frame of the lower plate. Then the clamping frame of the top plate is guided onto the pants so that it lies between the elastic covers of the lower and the upper clamping frame. This is followed by an adjustment of the two clamping frames on the vertical guides downwards, whereby the covers are stretched and slide with their edge areas down over the edges of the lower plate.
- the top plate is lowered onto the bottom plate and presses the trousers which are kept stretched.
- the press plates are opened, ie the upper plate, together with its clamping frame moving back to the starting position, is moved upwards and possibly swung away, whereupon the cover also the trousers can be removed.
- the invention is based on the object of specifying an ironing machine in which items to be ironed can be stretched flat before ironing and accumulation of material - even in the case of multilayered items to be ironed - is avoided.
- An ironing machine each with one or more upper and lower molds, which are arranged such that they can be pressed against one another and have an ironing surface on their mutually facing sides, at least one, preferably each of the upper and lower forums having at least two clamping bars that can be moved perpendicular to the ironing surface are arranged with an elastically stretchable cover attached between them, characterized in that each clamping bar has its own drive device and can be moved independently of the other clamping bar (s).
- the elastic cover is no longer fastened in a rigid, only vertically movable clamping frame, it is possible to adapt the ironing material, e.g. on trousers, to the respective circumstances.
- the clamping bars on the side facing the knee of the pants can be held at the level of the ironing surface, while the clamping bars are guided downwards on the side facing the hollow of the knee. This will stretch the pants from the knee towards the back of the knee and pull the knee lining towards the back of the knee. An accumulation of knee lining in the region of the knee is thereby eliminated, whereby a clean crease can be obtained after ironing.
- an upper and a lower mold are provided, each of which is associated with an elastically stretchable cover that is present between two respective clamping bars, the two clamping bars on one side of the upper and lower mold by means of their respective ones Drive device can be moved independently of the two spars on the other side of the upper and lower mold.

- the elastically stretchable cover is a stretch cord.
- This stretch cord has the necessary stretching properties and is also heat-resistant, so that it has a long service life even with a large number of ironing pieces.
- the clamping system has two pairs of plates, each consisting of two plates, one pair of plates stretching a trouser flap in a transverse direction by moving the two plates apart, and the two pairs of plates being movable away from each other in a longitudinal direction.
- the trousers are inserted through a slit in the lower mold and the trouser covers are tensioned by a pair of sheets. After the sheet metal pairs have been moved apart in the longitudinal direction of the lower mold, the pants already lie largely flat on the elastic cover of the lower mold and can then be stretched further in the transverse direction by means of the elastic covers.
- a particularly advantageous further development of the invention is characterized in that the drive devices are pneumatic piston-cylinder units and that a control circuit is provided for connecting the piston-cylinder units to a compressed air supply or ventilation openings.
- the piston-cylinder units of the drive devices belonging to the lower clamping bars can be connected to the compressed air supply or the ventilation openings via a valve arrangement.
- the valve arrangement for each of the drive devices belonging to the lower clamping bars each has a check valve and a solenoid valve connected in parallel and controlled by a light barrier which indicates the presence of items to be ironed.
- the solenoid valves are in the blocking position when the light barrier does Indicates the presence of items to be ironed.
- This embodiment enables the upper mold, together with the upper stretchable cover, to be lifted off the ironing surface and from the items to be ironed after the ironing process, while the items to be ironed remain lying on the tensioned lower stretchable cover. This can prevent wrinkling and wrinkling. Only after the ironing material has been removed from the ironing machine can the lower stretchable cover be relaxed by moving the lower drive devices upwards.

- the upper stretchable cover 3 is carried by an upper front clamping bar 5 and an upper rear clamping bar 6.
- the lower stretchable cover 4 is made of a lower front spar 7 and one lower rear spar 8 worn.
- the clamping bars 5, 6, 7, 8 can be produced in a simple manner from a tube material, for example from light metal, and can be moved vertically in each case and are each driven by their own drive devices 9, 10, 11, 12. Hydraulic or pneumatic actuators, e.g. Cylinder-piston units. Electric drives are also conceivable in which the vertical movement is realized, for example, by a spindle gear.
- FIG. 1 Between the top plate 1 and the bottom plate 2, a piece of ironing 13, for example a pair of trousers, is inserted, schematically shown in FIG. 1.
- the ironing material 13 which can be seen in FIG. 1 consequently corresponds to a trouser leg which is tensioned by sheets 14 and 15 parallel to the top and bottom plates. With their narrow end faces, the sheets 14 and 15 create a fracture in the trouser leg 13, at which a crease later arises after ironing.
- the clamping bars 5 and 6 and thus also the upper stretchable cover 3 are located approximately at the level of the ironing surface of the top plate 1.
- the clamping bars 7 and 8 with the lower, stretchable cover 4 are located at the level of the ironing surface of the lower plate 2.
- the upper plate 1 is not above the lower plate 2 in the starting position, but is pivoted away laterally by means of a rotary guide (not shown) . Only after placing the items to be ironed 13 is the top plate 1 pivoted over the bottom plate 2 and can then be moved vertically onto the bottom plate 2.
- the ironing material 13 is first placed on the lower stretchable cover 4 and thus on the ironing surface of the lower plate 2. Then the upper stretchable cover 3 is moved vertically downwards by means of the drive devices 9 and 10 and the clamping bars 5 and 6 until it touches the ironing material 13. Subsequently, the upper front clamping bar 5 and the lower front clamping bar 7 are moved further vertically downwards by means of the drive devices 9 and 12, as a result of which the stretchable covers 3 and 4 are stretched and the strap material 13 lying in between is pulled smooth . Thereafter, the top plate 1 can be moved vertically downwards by means of a drive device (not shown) until finally the ironing material 13 is pressed by means of pressure, heat and / or moisture.
- the ironing machine according to the invention it is possible to exert a one-sided pull on the ironing material 13, as a result of which, for example, multilayer ironing material, e.g. pants consisting of an outer fabric and a knee lining can be pulled smoothly in the desired manner.
- multilayer ironing material e.g. pants consisting of an outer fabric and a knee lining
- FIGS 2a, 2b and 2c show, in schematic side views, how different pulling effects can be exerted on the ironing material 13 by different movement of the clamping bars 5, 6, 7, 8.
- FIG. 2a shows the principle described above, in which the front clamping bars 5, 7 are guided vertically and to a location below the ironing surface of the lower plate 2, while the rear clamping bars 6, 8 approximately at the height of the lower plate 2 are held.
- the course of the stretchable covers 3 and 4 can also be seen in FIG. 2a.
- the pulling action on the ironing material 13 takes place in this arrangement to the right, as shown by an arrow P1.
- the ironing material 13 is a pair of pants
- the pants lie on the lower stretchable cover 4 such that the knee region points to the left in FIG. 2a
- the pants are tightened in the direction of the arrow P1 to the right.
- a clean crease can be created without thickening due to the knee lining in the knee area be generated.
- FIG. 2b schematically shows an inverted arrangement in which the front clamping bars 5, 7 are held at the level of the ironing surface of the lower plate 2, while the rear clamping bars 6, 8 are moved further vertically downwards with the aid of the drive devices 10 and 11 . This creates a pulling effect to the left in the direction of arrow P2.
- FIG. 2c schematically shows the state of the art again, in which all the tie bars 5, 6, 7, 8 are moved downwards, as a result of which a train proceeding from the center of the ironing surface proceeds to the left and to the right in the direction of the arrows P3 and P4.
- the upper clamping bars 5 and 6 and the lower clamping bars 7 and 8 are each rigidly connected to one another to form a clamping frame. A separate movement of the clamping bars is therefore not possible.
- FIG. 3a to 3c schematically show the method for ironing already described above with the ironing machine according to the invention.
- the ironing material 13 i.e. the pants
- the top plate 1 with the upper stretchable cover 3 is in a pivoting position, so that the bottom plate 2 is easily accessible for placing the pants 13 on.
- Fig. 4a shows a schematic side view
- Fig. 4b shows a schematic Top view of part of a particularly advantageous embodiment of the ironing machine. It can be seen that the lower plate 2 has a slot
- the clamping bars 5.6.7.8 can be moved not only vertically but also horizontally to the ironing surface. In this embodiment too, a desired tensile effect on the ironing material 13 can be obtained, but a larger installation space is required for the movement of the clamping bars 5, 6, 7, 8.
- the control and coordination of the pneumatic or hydraulic cylinders or the electric motors is carried out by means of suitable control circuits, as are usually used.
- FIG. 5 schematically shows an example of a circuit for a pneumatic system for driving the clamping device.
- a pressure unit 18 supplies the entire system with constant air pressure.
- the drive devices 9, 10, 1, 12 of the clamping bars 5, 6, 7, 8 can each be controlled via two 5/2-way valves 19, 20.
- the 5/2-way valves 19.20 are each actuated by a solenoid valve 21, 22, wherein the solenoid valves 21.22 can be switched electrically into a blocking and a passage position, whereby the 5/2-way valves 19, 20 against spring force be ⁇ actuated.
- the operation is explained using the example of valves 19 and 21. In the initial state, the solenoid valve 21 locks, as a result of which the 5/2-way valve 19 is in position 19a.
- the 5/2-way valve 20 is actuated by the solenoid valve 22 between the positions 20a and 20b.
- the 5/2-way valve 20 is in position 20a, as a result of which lower chambers of the drive devices 10 and 11 designed as cylinder-piston units are connected to the pressure side.
- the clamping bars 6 and 8 together with the pistons are at the top dead center.
- the upper chambers of cylinders 9 and 10 are vented via 5/2-way valves 19 and 20, respectively.
- solenoid valves 23 and 24 and non-return valves 25 and 26 are inserted between the upper chambers of the cylinders 11 and 12 and the ventilation side.
- the solenoid valves 23, 24 are actuated via the light barrier 1, as will be explained later. They are connected in parallel to the check valves 25, 26.
- the upper chambers in the cylinders of the drive devices 9 and 12 are then supplied with compressed air and the pistons are pressed down accordingly.
- the compressed air is supplied to the upper chamber of the drive device 12 via the check valve 25 because the solenoid valve 23 has already been closed on the basis of the signal from the light barrier 17.
- the stretchable covers 3 and 4 are pulled over the edge of the lower plate 2 and, as already described several times, stretch the pants 13 in between, so that the upper plate 1 can then iron the pants 13.
- the top plate 1 is raised again and the solenoid valve 21 also returns to its original position, so that the 5/2-way valve 19 comes into position 19a by means of spring force.
- the solenoid valve 23 is kept closed, which means that only the upper chamber in the cylinder of the drive device 9, but not in the cylinder of the drive device 12 is vented.
- the upper chamber in the cylinder of the drive device 12 cannot be vented because, on the one hand, the solenoid valve 23 is closed and, on the other hand, the check valve 25 blocks in the venting direction.
- the solenoid valve 23 is closed and, on the other hand, the check valve 25 blocks in the venting direction.
- the valve 23 and also the valve 24 remain in the closed position. Only after the trousers 13 have been removed from the ironing machine are the solenoid valves 23 and 24 released via the light barrier 17, so that the upper chambers of the cylinders of the drive devices 11 and 12 can be vented. Of course, the same procedure also applies to the actuation of the rear clamping bars 6 and 8. Here, the upper chamber of the cylinder is blocked in the drive device 11 by means of the solenoid valve 24, and its ventilation takes place via the check valve 26.
