Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for smoothing out wrinkles in clothing, especially clothing for the upper body, using steam and hot air, comprising at least one platform on which the clothing is placed. and in which the stand consists of at least one height-adjustable upper bust and a movable lower edge holding device for holding and tensioning the edges of the garment.

BACKGROUND OF THE INVENTION Devices of this type are used in the production of clothing, in particular for the production of blouses, dresses, shirts and the like, for smoothing out wrinkles or for so-called finishing. In this case, the wrinkle removal or treatment of the clothes is usually carried out today in a treatment chamber, into which a table covered with clothes is mechanically introduced and removed. In particular, the edge retaining device located at the lower end of the platform
It serves to hold the lower edge of the garment during garment processing, the actual holding process being preceded by an edge tensioning process, in particular in the direction of the side seams of the garment. For this purpose, the edge retaining device can be moved by hand step by step depending on the size of the garment or the like. This known method of operation is time-consuming and has the disadvantage that the shifting or tensioning is carried out without taking into account the fabric tensioning forces that are permissible in the different fabrics of different garments. The same can be said for a bust (shoulder support) whose height can be adjusted.

Therefore, it is an object of the invention to provide a device of the type mentioned at the outset, in which the movement of the bust (shoulder support) and/or the edge support is at least shorter and/or smaller. The goal is to improve it so that it can be done with less effort.

Means for Solving the Problem In order to solve this problem, the structure of the present invention is such that the bust and/or edge holding device is mechanically movable in an almost stepless manner. Functions and effects of the invention With the structure of the present invention, it is possible to adjust and reproduce the tension force allowed for different types of clothing, depending on various woven fabrics, at the time of tension. In particular, the mechanical adjustability saves the operator effort previously required.

EMBODIMENTS In an advantageous embodiment of the invention, the bust and/or edge retention device is provided with a tension measuring device, the tension measurement device being arranged such that the bust and/or edge retention device It is arranged to be movable in relation to the fabric tension. By measuring the tension force and subsequently controlling the movement of the bust or edge holding device, the operator can now determine whether the delivered garment corresponds dimensionally to the previously processed garment. There's no need to worry about it. This is because the device automatically adjusts to the correct tension value.

The housing, the edge retainer and/or III! It is advantageous if the image is movable using electromechanical and/or pneumatic displacement devices. In this case, the bust is adjusted in height and the edge holder is adjusted in diameter. Such electromechanical or lightning-pneumatic transfer devices have proven to be extremely robust in operation and are quick to operate.

In another advantageous embodiment in which the edge retention device and/or the bust are moved by means of lightning, pneumatic displacement devices, the displacement device for the bust and edge retention device is loaded with pressurized air on both sides. It is advantageous to have as few as possible working cylinders. At least one positioning valve is arranged in the pressurized air supply line for the working cylinders, which positioning valve can It is suitable for fixing working cylinders that can be moved in and can be loaded on both sides at any position of their stroke. Such universal positioning valves can be used to achieve the desired control of tensioning or displacement devices. It can be easily implemented.

In another advantageous embodiment of the invention, the edge retaining device has a body with at least one releasably movable tension profile 1, around which the edge of the garment surrounds. . With this embodiment, it is usually unnecessary to attach separate movable tensioning bodies, especially if these tensioning bodies have an approximately semicircular cross section.

In a further advantageous embodiment, a pair of stationary moldings VC are arranged between the movable tension moldings, on which the front and back sides of the garment are located.
In order to effectively apply a vertical force to the garment, it is advantageous if tightening surfaces are arranged opposite to each other on the molded body, and the tightening surfaces are tensioned against the molded body while tightening the garment. be. For tensile tensioning, electro-pneumatic devices (tightening cylinders) are also suitable in this case.

In addition, the clamping cylinder for the tensioning profile or its clamping surface and the clamping cylinder for the clamping surface of −1 of the two stationary profiles are connected in parallel and share a common actuating means. The control is particularly simple if it can be activated simultaneously via the . In this case, it is advantageous if the second clamping cylinder for the other stationary profile clamping surface can be actuated separately. With this embodiment, the garment can first be placed over the bust and then the edges can be tightened in the area of the tape by closing the front tightening surface. Only after the final tensioning of the edge retaining device has been achieved can the remaining clamping surfaces be activated.

In a particularly simple and robust embodiment of the device according to the invention,
A tension molding is arranged movably over a defined range in the direction of tension generation. Furthermore, preadjustable holding means are provided, by means of which the movable tensioning molding can be moved as follows: is fixable so as to be operatively coupled to a transmitter that interrupts the oscillation. With this simple device, it is thus possible to preset the permissible tensioning force for the fabric, so that the tensioning process is interrupted by deactivation of the tensioning cylinder when the transmitter is actuated.

In addition, the mechanically movable edge holding device has two tensioning carriages which are movable in mutually opposite directions and guided approximately linearly via deflected tensioning ropes. It is advantageous to have This simple device
This ensures an absolutely synchronous operation of the tensioning carriages or of the tensioning bodies attached thereto, which are pulled in opposite directions, so that distortions of the garment during the tensioning process are reliably avoided. This tension rope is preferably operatively connected to the working cylinder.

Furthermore, the task would be further simplified if a programmable central control device was provided, via which the moving device as well as the tightening device could be controlled. This control device advantageously also controls other treatment programs (steam, drying), which treatment programs are started only after the garment has been tensioned and which, after the end of the treatment program, the garment is again loosened. Treated garments should be bubbled out of the device.

The tension molded body 41 and its holding method will be described in detail below with reference to FIG. 4. As can be seen from the drawing, a clamping cylinder 39 for a clamping surface 38 is fixed in place on the immovable frame 31. Stationary molded body 3
The fixings for 7 are not shown in this figure.

Deflection rollers 47, 48 are arranged symmetrically with respect to the central axis of the device coinciding with the longitudinal tensioning device 80;
A tension rope 46 is stretched between these deflection rollers 47 and 48. The tension rope 4 formed in this way
6 (see FIG. 5), a tensioning cylinder 45 is arranged, and this tensioning cylinder 45 is rigidly connected to a tension rope 46 via a connecting plate.
When the piston moves (see the broken line in Figure 4),
The tension rope 46 is moved in a clockwise direction, whereas when the piston rod of the tensioning cylinder 45 moves in, the tension rope 46 is caused to move in a counterclockwise direction.

Symmetrically with respect to or between the two straight sections of the tensioning rope, the tensioning carriage 44 can be moved longitudinally parallel to the two straight sections along suitable guides, not shown. Five of the tensioning carts 44 are tightly connected to the leading portion of the tensioning rope, and the other tensioning cart 44 is tightly connected to the trailing portion.

When the piston rod of the tensioning cylinder 45 is moved, the two tensioning carriages 44 are moved in opposite directions, that is, in each case by exactly equal amounts.

A tensioning body 41 is assembled on the tensioning carriage +4 in a manner that will be explained in more detail below. A tension surface 42 is rotatably attached to a tension carriage 44 so as to face the tension molded body 41. Furthermore, a tensioning cylinder 43 is pivotally connected to the tensioning carriage 44 , the piston rod of which is operatively connected to the tensioning surface 42 . When the piston rod of the tightening cylinder 43 enters, the tightening surface 42 is pressed against the tension molded body 41, and the edge of the garment between the two sections is firmly held.

In the following, the arrangement of the tension bottom form 41 in the tension trolley 44 will be described in detail with reference to No. 6.

In this case, both tensioning carriages 44 are constructed in a similar manner.

Similarly, the switch 52 attached to the tension trolley 44 is operated.

In the following, the control format of the green maintenance device 30 will be explained in the seventh section.
This will be explained in detail with reference to figures.

As can be seen from the drawing, the clamping cylinder 43 is connected in parallel with the clamping cylinder 35 and is supplied with pressure via two valves 63, 64 by a pneumatic device 60 followed by a pressure reducer 67. The valves 63, 64 are in this case controlled by a central control device 70 via control lines 73, 74.

The clamping cylinder 39, which presses the clamping surface 38 against the stationary shaped body 37, is controlled via its own valves 61, 62, which are connected to the control device 70 via its own control wires 71, 72. It is connected.

The tensioning cylinder 45, which causes the tension molded bodies 41 to move away from each other, is connected to a pneumatically controlled positioning valve 68. The positioning valve 68 is in this case controlled by the control device 70 via the valves 65, 66 and the control wires 75, 76, and thus:
When a signal flows through 10,000 of both control wires 75 and 76, the piston runs out of the tension cylinder 45, and when a signal flows through the other control wire, the piston runs into the tension cylinder 45. ,It is configured. Both control wires 7
5.76, the piston of the tensioning cylinder 45 is held firmly in the position it occupies at that moment.

The automatic tensioning operation of the edge retaining device 30 will be described in detail below with reference to FIG. As can be seen from the drawings, the electromagnet 51 is supplied with power via electric wires 78, 92, and 77.

In this case, the electric wire 77.92 is connected to a variable resistor Rp and a fixed resistor R in series with the variable resistor Rp. The strength of the current flowing from the network section 55 via the wires 79,77 can be adjusted via a variable resistor Rp, so that a preselected holding current flows through the electromagnet 51. This holding current now defines the force with which Ray 5-5O is firmly held in the yoke of electromagnet 51. Tension molded body 41
When the force acting on the lever exceeds the holding force of the electromagnet 51, the lever 50 pivots downward against the tensile force of the spring 54, and the switch 52 is operated. The switch 52 is connected to the electric wire 79
．． It is connected to the control device 70 via 91. The control device 70 further includes a relay 5 for inputting the holding magnet 51.
5 is provided.

In the following, the mode of operation or operation of the device according to the invention will be explained in more detail. 1. First, a worker hooks the clothes 1 onto the bust 10 and places the rims on the stationary molded body 33 and tension molded body 41 (.

After this manual work, the automated process begins.

Control device 70 is actuated in this case by actuation of a switch, not shown.

The control device 70 first activates the valve 62, so that the tightening surface 38 closes and the edge 4 of the garment 1 is tightened in the area of its zethane tape.

The controller 70 then connects the valve 66 and the positioning valve 6
8 is activated and the tension cylinder 45 runs. As a result, both tensioning carts 44 with the tensioning body 41 are moved away from each other via the tensioning rope 46, and by this separating movement of the tensioning cart 44, the edge 4 of the garment 1 is pulled apart by the tensioning formation 41. That is, when the force acting on the tension molded body 41 exceeds the holding force of the electromagnet 51 adjusted by the resistance Rp, it is pulled apart. death·
As soon as the magnet 5 falls off the holding magnet 51, the switch 52 is activated. Switch 52 sends appropriate signals to controller 70 via wires 91 and 79. Based on this signal, the control device 70 shuts off the valve 66, whereby the positioning valve 68 is brought into the holding position and the tensioning cylinder 45
is fixed at the position obtained at that moment. At this point, the control device 70 also controls the valve 64, so that the clamping cylinder 35, 43, which was not activated up to now, is activated and the clamping surfaces 34-, 42 are closed.

At this point, the control device 70 also activates the longitudinal tensioning device 80 (which will be explained in more detail later) via a connection not shown. After all tensioning processes have been completed, the control device 70 introduces a treatment program, ie steam treatment, drying process, etc. are carried out. After the processing program ends, the control device 70 operates the valve 65 for a predetermined period of time, thereby supplying pressurized air to the positioning valve 68, causing the piston of the tension cylinder 45 to move in, and the tension molded body 41 to move in its direction. Move to closed position. At the same time, appropriate measures are taken with respect to the longitudinal tensioning device 80 via connection lines, which are not shown here;
As a result, the garment 1 is almost loosened again.

After this, the valve 61.63 is controlled by the control device 70 so that the clamping cylinders 35, 39.43 and the clamping surface 34.3
8, 42 open to release the edge 4 of the garment 1. This allows the worker to remove clothing 1.

FIG. 9 shows the longitudinal tensioning device 8o in detail.

This longitudinal tensioning device ao is made up of a guide tube 81 which does not stop and has a rectangular cross section. Possibly located. The piston rod 83 is part of a longitudinal tension cylinder 85, and a cylinder base 86 of the longitudinal tension cylinder 85 is fixed to the frame 31 in a non-rotatable manner. Even though the piston rod 83 and the guide tube 81 are connected to the shoulder support 1o, when pressurized air is supplied to the longitudinal tension cylinder 85, the piston rod 83 runs and the shoulder support 1o is connected.
Push 0 upwards together with guide W81. Advantageously, this device and the edge retaining device 30 are provided with suitable transmitters that limit the longitudinal tension to a predetermined value. The control means detailed only for the edge retaining device 30 in FIG. 7 are identically constructed.

In a further advantageous embodiment of the invention, the sleeve tensioning device is also configured such that a predetermined, preadjustable tension force is not exceeded during tensioning of the garment 1 or remains constant during the actual processing. It is configured.
