Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the use of ironing products which are fitted over molds with lateral inflatable sleeves which are manipulated by means of a pressure medium.
Loading the inflatable tube bag with the ironing product to the sides is loaded with a pressure medium, and the mold with the overfitted ironing product is moved between two heated press plates, and the pressing of the press plates and the expansion of the inflatable tube bag are carried out. A method of ironing garments in which an item to be ironed is ironed by tensioning and thus crimping of the lateral parts of the item to be ironed onto the press plates, and a mold which can be run between two heated press plates and which can be run from it. The present invention relates to a garment ironing device, which is provided with a lateral inflatable tube bag whose dispersion can be operated with a pressure medium.

PRIOR ART In the method and device known from DE 24 14 702, the mold has only one inflatable tube bag extending over the central part and the lateral parts, said inflatable tube being The bag is fitted over the support or pace plate. Arranged inside the inflatable tube bag are controllably movable support and hold-down elements of the reservoir for tensioning the ironing product. The outer part of the inflatable tube bag located in the shoulder area of the ironing product is fixed to the shoulder support element using a lace or similar so that this part can be moved together with the support element into the basic position and into the working position. has been done.

Placing the support and restraint elements inside the inflatable tube bag results in high costs.

If such an element is removed and the ironing article is to be stretched and ironed exclusively by pressure medium loading of an inflatable tube bag, this element is removed and the upper outer shoulder part is then fixed to this element. It is clear that significant disadvantages arise based on the fact that this is not the case.

In this case, it is particularly important that the upper part of the inflatable bag, which is folded down when the ironing item is placed over the mold, often does not move to an outward position during the subsequent tensioning process.
It may get caught in the folded state. As a result, not only the ironing product is not properly stretched and ironed in the fold-in area of the bulge, but also the central part and the lower side parts following the fold-in area are not properly stretched and ironed. because,
The upper part of the inflatable tube bag may not be tensioned correctly.
This is because it will have an unfavorable effect on the inflatable tube bag portion or the ironing product portion at the same location.

A device with a mold having a laterally separated inflatable tube bag is disclosed in particular in German Patent Application No. 1116
No. 189 and U.S. Patent No. 3257
No. 057 and No. 3,595,450. However, few measures have been taken to avoid the above-mentioned drawbacks even in these devices, or, for example, US Pat. No. 52,570
This is not necessarily necessary if the press plate is not guided away beyond the area of the inflatable tube, as in the device described in '57.

Furthermore, from German Patent No. 1154785, ironing on the mold stretches the item laterally;
It is also known to arrange a fixed circular spring-forming rod at one end, approximately in the central plane of the mold, instead of an inflatable tube bag or the like.

Problem to be Solved by the Invention The object of the invention is to improve a method and a device of the initially mentioned type so that the above-mentioned disadvantages do not occur. Particularly in this case, it is to be ensured that the entire (body) part of the ironing item to be ironed is pressed onto the active surface of the press board without the formation of wrinkles.

Means for solving the problem The means of the invention for solving this problem consists in that, in a method of the type mentioned at the outset, the upper lateral ends of the inflatable tube bag are fitted with a spring force while the ironing article is being fitted over the bag. 1. In the apparatus of the type mentioned at the beginning, the inflatable tube bag is pulled inward toward the center of the mold by the pressure medium, and the inflatable tube bag is stretched by a pressure medium load that overcomes the spring force. The main feature is that a spring is provided to pull at least the upper part of the outer region of the tube bag toward the center of the mold.

Effects of the Invention The method and device according to the invention avoids, in particular, the pinching of the lateral inflatable bag parts during pressing (closing) of the press plates, and the self-locking effect of these parts during inflated tensioning. be done. The side ironing part to be ironed must be fully ironed (the upper, middle and lower parts), and the upper part of the inflatable bag should be fully ironed (the expanding part and the corresponding ironing part should be ironed properly). Due to the movement of the parts, the ironing is done without the formation of wrinkles.This is especially true when the parts of the inflatable bag are inflated only after the closing of the press plate, so that the part of the inflatable bag remains folded. It is also achieved when the risk is particularly high.

Advantageously, the spring consists of a spring rod, in particular a curved spring wire, which extends into the interior of the inflatable bag and which extends inside the upper lateral end of the inflatable bag. It is stretched in advance so as to be pressed toward the center of the mold. In this case, the lower end of the curved spring wire is fixedly stretched, so that the curved spring wire protrudes upward.

The present invention may be used in molds having inflatable tube bags extending over the center and side portions of the mold, as well as molds having separate lateral inflatable tube bags. The present invention is characterized in that the press plate extends into or beyond the area of the inflatable tube bag, and that the press plate is curved or retracted to match the cross-sectional shape of the mold. It is particularly advantageous when used in such devices.

Example Next, the present invention will be explained in detail based on illustrated embodiments.

The apparatus shown in FIG. 1 works with two similarly constructed molds 10 and 11, each of which is located alternately inside or outside a press 12. The mold 10 is located in FIG. 1 external to the pool press 12 from which the laundry is removed and applied. The molds 10 and 11 can be moved into and out of the press in a controlled manner along rails (not shown).

Type i0. i1 has an approximately rectangular body 13 forming a mold frame, and one inflatable tube bag 14, 15 is attached to each narrow side of the pace body. The purpose of the inflatable tube bag 14,15 is to stretch and iron laundry or shirts and to be able to adapt it to different sizes.

The upper corners of the inflatable tube bag 14 or 15 are pretensioned inwardly toward the base body 13 by spring force. In the embodiment shown in FIG. 2, the spring force is obtained by a spring profile or a curved spring wire 16 or 17.

These curved spring wires 16, 17 are held immovably relative to the base body 13 with their lower ends 18 and 19, which in the illustrated embodiment form a cross-shaped element 20 and 21. The L-shaped member is fixed with one leg to the base body 13 and with the other leg to the lower end 1 of the curved spring wire 16,17.
Holds 8 or 19. In other words, curved spring wire 1
6.17 protrudes upward. In this case, the lower end 18, 19 of the curved spring wire passes through a small opening in the assigned inflatable tube bag 14 or 15, so that a large part of the curved spring wire 16 or 17 passes through the inflatable tube bag 14 or 15. extends inside. The upper end 22 or 23 also extends from the inflatable bag 14 or 15 through a small opening and is bent to form a clip 24 (FIG. 4). Using the clip 24 cooperating with the opening, the upper end of the inflatable tube bag 14 or 15 can be connected to a curved spring line.
,.

It is held at the upper end 22 or 23 of the material 16,17. The curved spring wires 16 and 17 are now pretensioned so as to press the inflatable tube bag 14 or 15 and at least its upper end inwardly towards the base body 13.

In FIG. 2, the inflatable tube bag 14 with the curved spring wire 16 shown on the left side of the drawing is shown in an inflated state, whereas the inflatable tube bag 15 on the right side of FIG. 2 is substantially evacuated. There is.

The spring force of each curved spring wire 1.6 or 17 is selected to be smaller than the outward force of the inflatable tube bag 14 or 15 when loaded with pressure medium. This allows perfect expansion of the inflatable tube bag. When the inflatable tube bag 14.15 is evacuated, the curved spring wire 16.17 presses inwardly around the upper end of the inflatable tube bag 14.15, so that the inflatable tube bag 14.15 is evacuated in an orderly and undesirable manner. Folds without forming wrinkles. This point will be explained in detail in connection with FIG.

The inflatable tube bags 14, 15 each have a hose-like connection 25 or 26 at their lower end, which is connected to a pressure medium distributor 27, for example for compressed air.

In the illustrated embodiment, the pressure medium distributor 27 is connected to the pace body 13.
The base body is connected to the base body and is movable together with the base body.

The lower outer corners of the inflatable tube bags 14, 15 are additionally pretensioned approximately vertically downwards via springs 28, 29, respectively.

FIG. 6 shows the mold 11 with the inflatable tube bag 14.15 and the crimped press plate 40.41 in a sectional view. The base body 13 of the mold 11 has an inner frame with vertical moldings 30 extending parallel to each other;
The molded body forms a support mechanism. Two metal support plates 31 facing each other are fixed on the molded body. On its outwardly facing side, this support plate carries elastic supports in the form of spring mats, which support a plurality of springs 3 with a base plate 32 and a spring cap 57.
It consists of 3. The spring 33 is pressed against the first textile lining 34. The basic structure of this type consists of two U-shaped covers 35 that laterally overlap each other.
．． It is surrounded by 36. Two covers35.
36 is made of or covered with a fibrous material.

The mutually overlapping legs of the covers 35 and 36 are connected to each other in the longitudinal center plane, in particular by rivets 37. The rivet 37 is also a vertical strip 38,3
Covered by 9. Inflatable bags 14 and 15 are attached in a manner known per se to the narrow sides of base body 13, that is to say to the mutually overlapping legs and strips 3B, 39 of covers 35 and 36.

Press plate 4 arranged mirror-symmetrically with respect to center line 42
0 and 41 have a hollow chamber 43 inside the reservoir for heating the press plate, for example with oil or steam. The chambers formed between the mutually facing curved surfaces of the press plates 40, 41 are adapted to the cross section of the base body 13 in the central region and on both sides in the region of the inflatable tube bags 14 and 15. and tapers toward the center line 42.

The inflatable tube bags 14 and 15 are shown in their starting position in solid lines, in which the curved spring wires 16 and 17 extend inwardly from the upper corners of the inflatable tube bags 14 and 15 into the base body 13. Or it is pressed against the strip 38, 39. As can be seen from the drawing, the inflatable tube bags 14 and 15 in this case have a neat, uncreased contour. The two dot-dash lines indicating the inflatable tube bags 14 and 15 indicate a half-inflated intermediate position and a fully inflated end position, respectively. As is clear from this, when the inflatable tube bags 14 and 15t are inflated, the outer wall of the inflatable tube bags deforms as it unfolds,
and gradually increases in size to fit the contours of the curved surfaces of press plates 40 and 41. In this case, (・The formation of wrinkles is reliably avoided.Furthermore, the inflatable tube bag 14.
It is also avoided that parts of the press plates 40, 41 are folded over and wedged between the cover 35 or 36 and the assigned press plate 40 or 41, for example.

The final position occupied by the inflatable bag is, of course, also related to the size of the garment to be ironed. It is clear that a relatively large range of adaptations to different garment sizes is provided and that different garment sizes can be compensated for exclusively by inflating the tube bags 14, 15 to different sizes. As is further evident, the configuration of the inflatable tube bag 14.15 with curved spring wires 16 and 17 is particularly important for the inflatable tube bag 14.1.
It is advantageous if the inflation of 5 takes place only when closing the press plates 40 and 41. It is precisely in this type of operation that the "curved chamber" narrows outward.
If a press plate 40, 41 shaped to have a shape is used, there is a particularly great risk that parts of the inflatable tube bag 14, 15 will become pinched or creases will form.

FIG. 4 shows the upper end 22 of the curved spring wire 16. As shown in FIG.

The upper end 22 is in this case first of all bent outwards (relative to the inflatable tube bag 14) and then bent back in a double inversion curve. As a result, a clip 24 is formed, and the inflatable tube bag 14 is attached to the clip.
The upper edge of the can be inserted. This becomes clearer when referring also to FIG. 5, which is a plan view showing a cross section of the upper end 22 of the curved spring wire 16 and the inflatable tube bag 14. The curved spring wire 16 is inserted from above through the opening of the inflatable tube bag 14 until the inflatable tube bag is held by the clip 24.

FIG. 6 shows an embodiment of the inflatable tube bag used. In this case, the inflatable tube bag 15 located on the right side in FIGS. 1 and 3 is taken up. Inflatable tube bag 1
5 is a hollow body having a wall 44 (see FIG. 6a showing a cross section along the line AB in FIG. 6). Said wall 4
4 is in contact with the narrow side wall of the base body 13. Another inflatable wall 45 forms, together with the wall 44, an essentially inflatable hollow body. A tongue-like piece 46 or 47 is attached to the connecting area between the two.

The tongues serve to secure the inflatable tube bag to the base body 13 more effectively. The tongues 46, 47 can inter alia have laces or fastenings.

Figure 6a shows curved spring wire rods 16 and 17 inside the inflatable tube bag.
The location is clearly indicated.

An eye 50 is provided in the lower outer corner of the inflatable bag, in which a spring 28 or 29 can be suspended. Of course, the inflatable tube bag is sealed at this point, for example, by the sealed tuck part 51.
achieved by.

In order to better hold the inflatable bag on the base body 13, the inflatable bag is suspended on shoulder-sleeve protrusions (not shown), in which case a clamping part 52 for the sleeve protrusion is provided. It is being This detail is clear from FIG. 6b, which shows a cross section along line CD in FIG. In this region, the inflatable bag has two chambers 53 and 54 which communicate with each other and have a clamp 52 between them.

These chambers 53, 54 can of course also be separated from the other interior chambers of the inflatable bag, as shown by a gas-tight separating seam 55.

The dot-dash line 56 in FIG.
The contour line is indicated by a dashed line 17a.

The invention is not limited to the illustrated embodiment, but can be implemented with various different embodiments.
