Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for overfitting ironing products onto molds with lateral inflatable tube bags operated by a pressure medium, in order to stretch the ironing products laterally. The inflatable tube bag is loaded with a pressure medium, and the mold together with the overfitted ironing product is moved between two heated press plates, and the pressing of the press plates, tensioning of the inflatable tube bag and the lateral movement to the press plate are carried out. A method of ironing garments in which the ironing article is ironed by crimping the parts of the ironing article, and a mold is provided which can run between two heated press plates and which can run from it. The present invention relates to a garment ironing device comprising a lateral inflatable bag which 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 and lateral parts of the mold; The bag is fitted over the support or base plate. Controlled and movable support and restraint elements for tensioning ironing items are arranged inside the inflatable tube bag. The outer part of the inflatable tube bag located in the shoulder area of the ironing product is arranged so that it can be moved with the support element into the basic position and into the working position by means of a lace or the like.
Fixed to the shoulder support element.

Locating the support and restraint elements inside the inflatable bag causes high costs. If it is desired to remove such an element and to carry out the tensioning and ironing of the ironing item exclusively by means of the pressure medium load of the inflatable tube bag, then this element must be removed and the upper outer shoulder part must be attached to it. It is clear that significant disadvantages arise due to the discontinuation of fixation. In this case, in particular, the upper part of the inflation tube, which is folded down when the ironing item is placed over the mold, often does not move to an outward position during the next inflation (stretching), but instead is stuck in the folded state. It may happen. 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. This is because the upper part of the inflatable tube bag is not stretched 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 bag is known from, inter alia, German Patent Application No. 1116189 and U.S. Pat. No. 3,257,057 and U.S. Pat. No. 3,595,450. be. However, few measures have been taken in these devices to avoid the above-mentioned drawbacks, or, as in the device described in US Pat. This is not necessarily required if you are not guided to leave.

Furthermore, German Patent No. 1 154 785 discloses that, in order to laterally tension the ironing item in the mold, a fixed material, instead of an inflatable bag or the like, is provided at one end approximately in the central plane of the mold. It is also known to arrange circular spring-shaped rods.

Problems to be Solved by the Invention The object of the present invention is to solve the problem so that the above drawbacks do not occur.
The object of the invention is to improve methods and devices of the type mentioned at the outset. 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 subjected to a spring force while being fitted over the ironing product. The inflatable tube bag is pulled inward toward the center of the mold by the spring force, and the inflatable tube bag is stretched by a pressure medium load that overcomes the spring force. A spring is provided for pulling at least the upper part of the outer region toward the center of the mold.

Effect of the invention By the method and apparatus according to the present invention, in particular,
This prevents the pinching of the lateral inflatable tube bag portions when pressing the press plates together (closing), as well as the self-locking action of these portions during inflation (stretching). All the lateral ironing parts to be ironed (upper, middle and lower parts) are exposed to the well-developed inflation of the upper inflation tube part and the corresponding movement of the ironing parts. Based on the ironing without forming wrinkles. This is achieved in particular even when the risk of the inflatable bag part remaining folded is particularly high, such as when the inflatable bag is inflated only after the press plate has been closed.

Embodiment The spring advantageously consists of a spring profiled rod, in particular a curved spring wire, which extends inside the inflatable sleeve and extends inside the upper lateral end of the inflatable sleeve. 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,
As a result, 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 is configured such that the press plate is curved or retracted to adapt to 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 shown in FIG. 1 external to the press 12 for removing and covering the laundry. The molds 10 and 11 can be moved into and out of the press in a controlled manner along rails (not shown).

The molds 10, 11 have a substantially rectangular base body 13 forming a mold frame, each of which has an inflatable tube bag 14, 15 attached to each of its narrow sides. The purpose of the inflatable tube bags 14, 15 is to iron laundry or shirts taut and to be able to accommodate 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-shaped rod or a curved spring wire 16 or 17. These curved spring wires 16, 17 are held immovable relative to the base body 13 with their lower ends 18 and 19, which in the illustrated embodiment are connected via L-shaped elements 20 and 21. The L-shaped member is fixed to the base body 13 with one leg and connected to the curved spring wire 1 with the other leg.
The lower end portions 18 or 19 of 6, 17 are held. That is, the curved spring wire rods 16 and 17 protrude upward. In this case, the lower ends 18, 19 of the curved spring wire pass through a small opening in the assigned inflatable tube bag 14 or 15, so that most of the curved spring wire 16 or 17 passes through the inflatable tube bag 14 or 15. It extends inside 15. 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 inflatable tube bag 1 is
The upper end of 4 or 15 is a curved spring wire 16,1
It is held at the upper end 22 or 23 of 7.
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. There is. The spring force of each curved spring wire 16 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. When the inflatable tube bags 14, 15 are evacuated, the curved spring wire rods 16, 17 are removed from the inflatable tube bags 14, 15.
The inflatable tube bag is folded neatly and without undesirable creases. 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 the lower end,
The connection is, for example, a pressure medium distributor 2 for compressed air.
7 is connected. In the illustrated embodiment, the pressure medium distributor 27 is connected to the base body 13;
And it can run together with the base body.

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

FIG. 3 shows the mold 11 with the inflatable tube bags 14, 15 and the press plates 40, 41 pressed together in a sectional view. The base body 13 of the mold 11 is
It has an inner frame with vertical profiles 30 extending parallel to each other, said profiles forming a support mechanism. Two metal support plates 31 facing each other are fixed on the molded body. This support plate carries on each outwardly facing side an elastic support in the form of a spring mat,
The mounting consists of a base plate 32 and a plurality of springs 33 with spring caps 57. The spring 33 is pressed against the first textile lining 34.
This type of basic structure is laterally surrounded by two U-shaped covers 35, 36 which overlap one another. The two covers 35, 36 are made of textile material or are covered with textile material. The mutually overlapping legs of the covers 35 and 36 are connected to each other in the longitudinal central plane, in particular by rivets 37. Rivets 3
7 is again covered by vertical strips 38, 39. The narrow side of the base body 13, that is, the cover 35
and 36 and to the mutually overlapping legs 38, 39, inflatable tube bags 14 and 15 are attached in a manner known per se.

The press plates 40 and 41, arranged mirror-symmetrically with respect to the center line 42, have an inner hollow chamber 4 for heating the press plates, for example with oil or steam.
It has 3. The chamber formed between the mutually facing curved surfaces of the pressing plates 40, 41 is 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. It tapers toward the center line 42.

The inflatable tube bags 14 and 15 are shown in their starting positions by solid lines, and in this starting position the curved spring wires 16 and 17 are connected to the inflatable tube bags 14,
The upper corner of the base body 13 is turned inward.
Alternatively, it is pressed against the strips 38 and 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, the inflatable tube bag 14
When inflating and 15, the outer wall of the inflatable tube bag 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, it is also avoided that a part of the inflatable tube bags 14, 15 is folded up when the press plates 40, 41 are closed and is sandwiched, for example, between the cover 35 or 36 and the assigned press plate 40 or 41. It is being

Of course, the final position of the inflatable tube bag is
It is also related to the size of the garment you are trying to iron. 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 by exclusively inflating the tube bags 14, 15 to different sizes. As is further clear, the configuration of the inflatable tube bags 14, 15 with the curved spring wires 16 and 17 is particularly advantageous when the inflatable tube bags 14, 15 are inflated by the press plates 40 and 41.
It is advantageous if this is done for the first time when closing. In this type of operation, especially when press plates 40 and 41 are used, in which the "curved chambers" are formed to become narrower toward the outside, a portion of the inflatable tube bags 14 and 15 The risk of pinching or forming creases is particularly high.

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. This creates a clip 24 into which the upper edge of the inflatable tube bag 14 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 in 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. The inflatable tube bag 15 is attached to the wall 44 (A in FIG.
6a, which shows the cross-section along line B). The wall 44 is in contact with the narrow side wall of the base body 13. The further inflatable wall 45 forms together with wall 44 the actual inflatable hollow body. In the connection region between walls 44 and 45 a tongue 46 or 47 is fitted, respectively, which serves to more effectively fix the inflatable bag to the base body 13. Attached to the tongues 46, 47 is, inter alia, a decorative cord or elastic cord 48 or 49, with which the inflatable tube bag can be fixed to the base body 13.

Figure 6a shows the curved spring wire 1 inside the inflatable tube bag.
The positions of 6 and 17 are clearly indicated.

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

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. ing. This detail is shown in section 6b, which shows a cross section along line CD in FIG.
It is clear from the figure. In this region, the inflatable tube bag has two chambers 53 and 54,
These chambers communicate with each other and have a clamp 52 between them. These chambers 53,
54 can of course also be separated from other interior chambers of the inflatable bag, as shown by an airtight separation seam 55.

The dash-dot line 56 in FIG. 6 further schematically shows the inflatable tube bag in the folded state, in which case the outline of the curved spring wire 17 is indicated by the dash-dot line 17a.

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