DE8525550U1 - Device for ironing outer garments such as jackets, coats, etc. - Google Patents

Description

Description;

The innovation relates to a device for ironing outer garments, such as jackets, coats and the like, by means of steam and hot air, preferably in a treatment chamber, whereby the garment is pulled onto a shaped body (shoulder support) that supports it in the shoulder area and can be moved up and down by a pneumatic adjustment device, and a lower area of the garment can be clamped by a hem holding device with at least two clamping shaped pieces that can be moved relative to one another by an adjustment device.

In a known device of this type (DE-AS 12 56 617) it is necessary to operate the clamping molds in the area of the hem holding device by hand in order to hold the hem of the

-2-

item of clothing. The shoulder support is operated by a pneumatic longitudinal clamping device. For this purpose, a lifting cylinder (height clamp) is arranged in a base frame of the device, which can be operated manually via a valve.

This known device is largely dependent on manual operation. Of particular importance , however ^, is the lack of consideration ^of the permissible fabric tension. Rather, the operator must take the permissible fabric tension into account at his own discretion when operating the device.

An older patent application (DE-OS 35 07 757) discloses a device of the type mentioned above, in which the shoulder support and hem holding device are electro-pneumatically operated. Measures are also provided to take into account the individual permissible fabric tension of the items of clothing. For this purpose, a height adjustment device for the shoulder support is controlled in a path-dependent manner. According to one embodiment of the known device, the stroke of the height adjustment device for the shoulder support can be adjusted in several stages by applying different levels of compressed air to a height adjustment cylinder.

Such a device allows the optimal adaptation and adjustability of the adjustment devices for the shoulder support and/or hem holding device to the permissible fabric tension of various items of clothing only by means of considerable electro-pneumatic effort.

The innovation is based on the task of further developing and improving a device of the type mentioned above so that the shoulder support and/or the hem holding device can be adjusted in a simple and particularly precise manner to different permissible fabric tensions.

&phgr; &lgr; * &lgr; as rc it

^ the Jiü treated garments are adjustable.

!To solve this problem, the device according to the invention is characterized in that the electropneumatic adjustment device (longitudinal tensioning device) of the shoulder support and/or the electropneumatic adjustment device (tensioning cylinder) of the tensioning moldings of the hem holding device have electrically (via the energy supply) controllable tensioning force limiting devices ^q for limiting the adjustment movement of the shoulder support and/or tensioning moldings when an adjustable, permissible fabric tension of the garment is reached.

Thanks to the innovative design of the device, when the very easily adjustable permissible load on the garment is reached, the lifting or adjusting movement for the shoulder support or for the tensioning molded parts of the hem holding device is interrupted, so that the relevant elements remain in the position corresponding to the permissible load on the garment. This makes it possible to adjust the permissible fabric tension in small steps or continuously with relatively little effort.

2g A particularly advantageous embodiment of the innovation is characterized in that clamping molded parts of the shoulder support and/or the hem holding device are arranged so as to be movable (levers) over a defined range in the direction of the resulting clamping force and are provided with pre-adjustable holding

OQ can be fixed by means of a device (electromagnet) in such a way that the clamping fittings come into active connection with a sensor (switch) that interrupts the clamping movement when a set clamping force is exceeded.

gg Further features of the device according to the invention are the subject of sub-claims 3 to 9.

As shown in Fig. 1, the device according to the invention for ironing items of clothing is arranged in a treatment chamber 2. The device has a shoulder support in the form of a bust 10, which is arranged on a longitudinal tensioning device 80. At the fastening point of the longitudinal tensioning device 80, it is surrounded by the hem holding device 30, which consists of tensioning clamps 40 on the right and left as well as a rear clamp and a front clamp 36. The entire arrangement is located on a frame 31.

As shown in Fig. ¹ Ig. 2, the frame 31 is seated on a rotary table 90 so that the device for putting on the garment 1 or for taking it off can be easily rotated about its vertical axis.

-&Igr;&Ogr;&Igr; On the frame 31, support columns 24 projecting upwards are attached to the right and left, on each of which are slidably seated lever locks 23 with coupled holding levers 22. The holding levers 22 have sleeve clamps 21 at their ends, so that these parts together form sleeve holders 20, to which the sleeves of the item of clothing 1 can be attached.

As shown schematically in Fig. 3, the hem holding device 30 is arranged around the longitudinal clamping device 80. It has two stationary molded pieces or pressure surfaces 33, 37, to which (outside) opposite clamping surfaces 34, 38 are assigned. The clamping surfaces 34, 38 can be pressed onto the stationary surfaces 33, 37 via hydraulic clamping cylinders 35, 39.

To the right and left of the longitudinal clamping device 80 there are clamping mold pieces 41, which are also assigned clamping surfaces 42 opposite each other (on the outside). The clamping surfaces 42 can be pressed onto the clamping mold pieces 41 via clamping cylinders 43. The clamping mold pieces 41 can be moved outwards or in the direction of the arrow shown in Fig. 3 together with the clamping surfaces 42 and their clamping cylinders 43. A possible end position of the clamping mold pieces 41 is indicated in dashed lines.

The shape of the stationary molded pieces 33, 37 and the movable clamping molded pieces 41 is selected so that in plan view an essentially ellipse results, so that the hem 4 of a garment 1 can be pulled onto the hem holding device 30.

In the following, the clamping molded parts 41 and their holder are described in more detail using Fig. 4. As can be seen from the figure, the clamping cylinders 39 for the clamping surface 38 are fixed to the fixed frame 31. The fastening for the stationary molded part

Symmetrical to the central axis of the device, which is connected to the

Longitudinal tensioning device 80 coincides, deflection rollers 47, 48 are arranged around which a traction cable 46 is tensioned

&kgr; traction cable 46 is firmly connected. If the tensioning cylinder 45

extends its piston (shown in Fig. 4 with dashed lines), the traction cable 46 is moved clockwise; g retracts the piston rod of the tensioning cylinder 45,

I the traction cable 46 moves anti-clockwise.

!Symmetrically to the two linear sections of the cable pull 15 or between them, tension carriages 44 can be moved longitudinally on corresponding-I guides (not shown), namely

The arrangement of the clamping molds on the clamping carriage 44 is explained in more detail below with reference to FIG. _46. Both clamping carriages 44 are equipped in the same way.

The clamping molded part 41 is articulated on the clamping carriage 44 via a lever joint 49 or a lever 50. In the position shown in Fig. 6, the clamping molded part 41 is tilted outwards by about 6° from the vertical. In this position, the end of the lever sits on the yoke of an electromagnet 51, which is firmly attached to the clamping carriage 44. The lever 50 also has an extension that extends beyond the lever joint 49, to which a spring 54 engages at one end, the other end of which is connected to the clamping carriage 44. The spring 54 is pre-tensioned in such a way that without external forces the arrangement assumes the position shown in Fig. 6 (compensation of the lever weight).

I If forces now act (to the right in Fig. 6) on the clamping | fitting 41, the lever 50 can pivot about the lever joint and assumes the position shown in dashed lines in Fig. 6. In this position, the end of the lever 50 actuates a switch 52, which is also attached to the clamping carriage 44.

In the following, the control of the hem holding device 30 is described in more detail with reference to Fig. 7.

As can be seen from this drawing, the clamping cylinders 43 are connected in parallel with the clamping cylinder 35 and via two valves 63, 64 from a compressed air device

60 with a downstream pressure reducer 67. The valves 63, 64 are controlled by a central control device 70 via electrical control lines 73, 74.

The working cylinder 39», which presses the clamping surface 38 onto the stationary molded part 37, is controlled by separate valves 61, 62 which are connected to the control device via their own control lines 71, 72.

The clamping cylinder 45 for moving the clamping molded pieces 41 apart is connected to a pneumatically controllable positioning valve 68. The positioning valve 68 is controlled by the control device 70 via valves 65, 66 or the electrical control lines 75, 76 and is designed in such a way that when a signal is received on one of these control lines, the piston is moved out of the cylinder 45 and when a signal is received on

_1K of the other control line into the cylinder 45.

If both control lines 75, 76 are not actuated, the piston of the clamping cylinder 45 is held in the position it has just reached.

The following describes the function of the automatic voltage

voltage setting of the hem holding device 30 is described in more detail with reference to Fig. 8. As can be seen from this figure, the electromagnet 51 is supplied with power via lines 78/ 92/ 77. An adjustable resistor R (and in series with this a &ogr;&Rgr;

fixed resistor R), the control resistor R can now be used to adjust the current intensity of a current coming from the power supply 53 via the lines 79 and 77, so that a

preselected holding current flows. This holding current be-30

If the force with which the lever 50 is held to the yoke of the electromagnet 51 is correct, if the force acting on the clamping molding 41 exceeds the holding force of the electromagnet 51, the lever 50 folds

The function or the mode of operation of the device according to the invention is explained in more detail below. First, the operator pulls the item of clothing 1 onto the bust 10 and places the hem 4 over the stationary and the tension carriage moldings 33 and 41, respectively. After this manual activity, the automated process begins. By operating a switch (not shown), the control device 70 is set in motion. The control device 70 first actuates the valve 62 so that the clamping surface 38 closes and the hem 4 of the item of clothing 1 is clamped in the area of its button strip. The control device 70 then switches on the valve 66 in such a way that the positioning valve 68 is actuated and the tension cylinder 45 extends. As a result, the two tension carriages 44 with the tension carriage moldings 41 are moved apart via the cable pull 46. By moving the tensioning carriages 44 apart, the seam 4 of the garment 1 is pulled apart by the tensioning molds 41 until the force acting on the tensioning molds 41 exceeds the holding force of the electromagnet 51 set by the resistance R. As soon as the lever 50 "falls off" the holding magnet 51, the switch 52 is actuated. The switch 52 sends a corresponding signal to the control device 70 via the lines 91 and 79. In response to this signal, the control device 70 switches off the valve 66, whereby the positioning valve 68 is brought into the holding position and the tensioning cylinder 45 is fixed in the position currently reached. At this point in time, the control device 70 also controls the valve 64, so that the previously unactuated clamping cylinders 35, 43 are actuated and the clamping surfaces 34, 42 are closed.

35

At this point, the control device 70 also operates the longitudinal tensioning device 80 via connections not shown here, which will be described in more detail later. After all the tensioning processes have been completed, the control device 70 then initiates the treatment program, it is

ijesteamed, dried etc. After the treatment program has ended, the control device 70 operates the valve 65 for a certain time, whereby the positioning valve 68 is pressurized with compressed air in such a way that the piston rod of the tensioning cylinder 45 retracts and the tensioning moldings 41 move into their "closed" position. At the same time, the corresponding measures are taken with regard to the longitudinal tensioning device 80 via connecting lines (not shown here), so that the item of clothing 1 is then essentially unstretched again. The control device 70 then controls the valves 61 and 63 so that the clamping cylinders 35, 39 and the clamping surfaces 34, 38 and 42 open and release the hem 4 of the item of clothing 1 so that the operator can remove the item of clothing 1.

The longitudinal clamping device 80 is described in more detail in Fig. 9. This consists first of all of a guide tube 81 with a substantially rectangular cross-section, which is arranged longitudinally displaceably on a piston rod 83 with a guide 84 and an anti-twist device 82. The piston rod 83 belongs to a longitudinal clamping cylinder 85, the cylinder base 86 of which is fixedly secured to the frame 31. The piston rod 83 and the guide tube 81 are connected to the shoulder support 10. If compressed air is supplied to the longitudinal clamping cylinder 85, the piston rod 83 extends and pushes the bust 10 (together with the guide tube 81) upwards. Advantageously, this device, as well as the hem holding device 30, is provided with corresponding sensor means which limit the longitudinal clamping force to a defined level. The control means, which were only described in more detail for the hem holding device 30 with reference to Fig. 7, are constructed equivalently.

In a further preferred embodiment of the invention, the sleeve tensioning devices are also designed in such a way that a certain pre-set tensile force is not exceeded when tensioning the garment 1 or is kept constant during the actual treatment.
