Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for smoothing out wrinkles in suits, coats and similar clothing using steam and hot air, preferably in a processing chamber. A bust (shoulder support) that supports the covered garment in its shoulder area and that can be moved up and down by means of an adjustment device.
and an edge retention device for clamping the lower region of the garment, the edge retention device having at least two tensioning bodies movable relative to each other by means of a further adjustment device. .

BACKGROUND OF THE INVENTION Devices of this type are used in the production of garments, in particular suits, coats, dresses and the like, to smooth out wrinkles in the garment during the finishing stage. This treatment of the garments, ie the action of steam and possibly hot air on the garments, takes place in a treatment chamber.

Known devices of this type (DE-PS-
1256617), the shoulder support for receiving the shoulder area of the garment to be treated can be moved up and down by means of a pneumatic cylinder. A manually operated valve is arranged in the air conduit leading to this cylinder. The running movement of the cylinder that raises and lowers the shoulder support is therefore controlled by hand.

Furthermore, this known device is provided with an edge retention device, which consists of two pairs of diametrically opposite clamping jaws, between which the edge portion of the garment is secured. It's starting to get clamped. For this purpose, each outer clamping jaw is designed to be radially movable by hand, i.e. via a push rod with a grip. Two further clamping jaws facing each other, which can also be shifted horizontally by hand via a push rod, cooperate with fixed opposing surfaces.

With this edge holding device, it is possible to tension the garment in the vertical direction by shoulder support, but it is not possible to tension the garment in the circumferential direction. Furthermore, the clamping mechanism of the edge retainer is operated by hand, making its handling rather cumbersome.

In addition, in the device disclosed in Japanese Patent Publication No. 47-27838, the shoulder support for clothes is configured to be able to move up and down by a mechanical transmission device, that is, a toothed belt transmission device, and this transmission device is reciprocating. It is designed to be operated by hand using a movable pivot lever.

Furthermore, in this known device, the edge holding device is constructed in the same way as in the known device described above, such that tension acting in the circumferential direction cannot be transmitted to the garment;
The clamping jaws distributed along the entire circumference only press the edge area of the garment towards the stationary cylindrical profile.

This known device is therefore also difficult to handle and there are problems in introducing optimal tension into the garment.

OBJECT OF THE INVENTION It is therefore an object of the invention to improve a device of the type mentioned at the outset in order to provide tensioning for the treatment of garments in the shoulder and/or edge area by means of an automatically movable tensioning mechanism. The object of the present invention is to provide a device that can be used to introduce adjustable and optimal tension into clothing.

Means for Solving the Problem In order to solve this problem, the configuration of the present invention includes:
The tension profile of the bust and/or edge retention device is arranged movably over a defined range in the direction of tension generation and can be fixed with preadjustable holding means, in which case the tension profile is adapted to be operatively connected to a transmitter which interrupts the tensioning movement of the bust adjustment device or the edge retention device adjustment device in the event of an exceedance of the adjusted tensioning force.

Effects of the Invention The adjustment device for the shoulder support and/or edge retention device is automatically switched off during the running movement for tensioning the garment, ie when an adjustable tension in the fabric of the garment is achieved. This tension buildup then acts on a movable switching mechanism (tension profile). This switching mechanism is preloaded with a load depending on the tension to be obtained in the fabric and is moved when the desired tension in the fabric is achieved. This shifting adjustment movement triggers a switching operation, which ends the running movement of the direct adjustment device.

The adjusting device is preferably designed as an electro-pneumatic tensioning cylinder. When the tensioning movement is interrupted, a positioning valve is actuated, which in the extended position is activated by the tensioning cylinder (working cylinder).
hold firmly.

In a further embodiment of the invention, the tension profile serving as the switching mechanism is arranged on a pivotable lever, which is held in the starting position by a holding mechanism with adjustable holding force, in particular an electromagnet. . This lever then produces a pivoting movement if the holding force is exceeded by a suitable load on the garment.

Embodiment As shown in FIG. 1, a garment smoothing device according to the invention is placed in a treatment chamber 2. The device has a shoulder support in the form of a bust 10, which is arranged above the longitudinal tensioning device 80. The longitudinal tensioning device 80 is surrounded at its fixing point by an edge retention device 30, which includes a left and right tensioning clamp 40, a rear clamp 32 and a front clamp 36.

Holding columns 24 extending upward are attached to the left and right sides of the frame 31, and lever fixing members 23 are disposed on both holding columns so as to be slidable along the respective holding columns. A holding lever 22 is connected to each of the holding levers 23 . The holding lever 22 has at its free end a sleeve clip 21, which together form a sleeve holder 20, to which the sleeves of the garment 1 can be fastened. .

As shown in FIG.
are arranged around the longitudinal tensioning device 80. The edge retaining device 30 has two stationary moldings or crimping surfaces 33, 37 at the front and rear, and on the outside of these crimping surfaces, a clamping surface 34, 38 is assigned opposite each other. Tightening surfaces 34, 38
can be pressed onto stationary molded bodies 33, 37 via hydraulic tensioning cylinders 35, 39.

Tension molded bodies 41 are provided on the left and right sides of the longitudinal tension device 80.
are provided, and tensioning surfaces 42 are likewise assigned to the outside of both tensioning profiles, facing each other. The clamping surface 42 can be pressed onto the tension molded body 41 via a clamping cylinder 43 . The tension molded body 41 is the tension surface 4
2 and its clamping cylinder 43 are movable outwardly, ie in the direction of the arrow shown in FIG. The possible end positions of the tension profile 41 are shown in broken lines in FIG.

The shapes of the stationary shaped bodies 33, 37 and the movable tensioned shaped body 41 are selected in this case to be approximately oval in plan view, so that the edge 4 of the garment 1 is held in the edge retention device 30. can be attracted.

The tension molded body 41 and its holding method will be described in detail below with reference to FIG. 4.
As can be seen in the drawing, a clamping cylinder 39 for a clamping surface 38 is fixed in place on the stationary frame 31 . The fixings for the stationary shaped body 37 are not shown in this figure.

Deflection rollers 47, 48 are arranged symmetrically with respect to the central axis of the device, which coincides with the longitudinal tensioning device 80, and a tension rope 46 is stretched over these deflection rollers 47, 48. . A tensioning cylinder 45 is arranged below the tensioning rope 46 formed in this way (see FIG. 5), which tensioning cylinder 45 is rigidly connected to the tensioning rope 46 via a connecting plate. When the tension cylinder 45 moves its piston (see dashed line in FIG. 4), the tension rope 46 is forced to move in the clockwise direction, whereas when the piston rod of the tension cylinder 45 moves in, the tension rope 46 moves It is forced to move in a counterclockwise direction.

Symmetrically or between the two straight sections of the tension rope, the tensioning carriage 44 can be moved longitudinally parallel to the two straight sections along suitable guides, not shown.
One of the tensioning carts 44 is tightly connected to the leading part of the pulling rope, and the other tensioning cart 44 is tightly connected to the trailing part.

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

The tensioning body 41 is assembled on the tensioning carriage 44 in a manner that will be described 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 moves in, the tightening surface 42 is pressed against the tension profile 41 and the edge 4 of the garment between the two parts is held firmly.

In the following, the arrangement of the tension molded bodies 41 in the tension carriage 44 will be described in detail with reference to FIG. 6. In this case, both tensioning carriages 44 are constructed in a similar manner.

The tension molded body 41 is pivotally attached to the tension truck 44 via a lever joint 49 and a lever 50. In the position shown in FIG. 6, the tension profile 41 has now been pivoted outwards by approximately 6 DEG with respect to the vertical. In this position, the end of the lever 50 is in contact with the yoke of the electromagnet 51, which is rigidly fixed to the tensioning carriage 44. The lever 50 further includes an extension extending beyond the lever joint 49 and on which a spring 54 acts at one end, the other end of which is connected to the tensioning carriage 44. There is. The spring 54 in this case has a preload such that the lever 50 occupies the position shown in FIG. 6 in the absence of an external force (lever weight compensation).

When a force acts on the tension molded body 41 toward the right as seen in FIG.
9 and occupies the position indicated by the dashed line in FIG. In this position, lever 5
The 0 end operates a switch 52 which is also attached to the tension trolley 44.

In the following, the control type of the edge holding device 30 will be described in detail with reference to FIG.

As can be seen in the drawing, the tensioning cylinder 43 is connected in parallel with the tensioning cylinder 35 and is supplied with pressure via two valves 63, 64 by a pneumatic device 60 which is followed by a pressure reducer 67. . Valve 6
3, 64 are in this case controlled by a central control device 70 via control wires 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 tension cylinder 45, which causes the two 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 a control device 70 via the valves 65, 66 and the control lines 75, 76, and in other words, both control lines 7
When a signal flows to one of the control wires 5 and 76, the piston moves out of the tension cylinder 45, and when a signal flows to the other control wire, the tension cylinder 45
It is configured to be driven into the vehicle. If no signal is sent to both control wires 75, 76, the piston of the tensioning cylinder 45 is held firmly in the position it just occupies.

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 drawing, the electromagnet 51 is powered via electric wires 78, 92, 77. Electric wire 7
7,92 is the variable resistor R _P and this variable resistor in this case
A fixed resistor R is connected in series with R _P.
The strength of the current flowing from the network section 55 via the wires 79, 77 can be adjusted via a variable resistor R _P so that a preselected holding current flows through the electromagnet 51. This holding current now defines the force with which the lever 50 is held firmly against the yoke of the electromagnet 51. When the force acting on the tension molded body 41 exceeds the holding force of the electromagnet 51, the lever 50 pivots downward against the tension of the spring 54 and operates the switch 52. The switch 52 is connected to the control device 70 via electric wires 79 and 91. Control device 70 for input of holding magnet 51
Further, a relay 55 is provided.

In the following, the mode of operation or operation of the device according to the invention will be explained in more detail. First, a worker hooks the garment 1 onto the bust 10 and places the edge 4 on the stationary molded body 33 and tensioned 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. Control device 70
first actuates the valve 62, which results in the tightening surface 3
8 is closed and the edge 4 of the garment 1 is tightened in the area of its button tape. The control device 70 then connects the valve 66, the positioning valve 68 is actuated and the tensioning cylinder 45 is moved out. As a result, the two tensioning carts 44 with the tensioning bodies 41 are moved away from each other via the tensioning ropes 46. Due to this separating movement of the tensioning carts 44, the edge 4 of the garment 1 is moved away from the tensioning formations 41. , that is, until the force acting on the tension molded body 41 exceeds the holding force of the electromagnet 51 adjusted by the resistance R _P . As soon as the lever 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 in the position currently obtained. At this point, the control device 7
0 also controls the valve 64, so that the hitherto inactive clamping cylinders 35, 43 are activated and the clamping surfaces 34, 42 are closed.

At this point, the control device 70 connects the longitudinal tensioning device 80 via a connection not shown.
(more on this later) are also activated. 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 is finished, the valve 65 is actuated for a predetermined period of time by the control device 70, thereby supplying pressurized air to the positioning valve 68, so that the piston rod of the tension cylinder 45 moves in. The tension molding 41 moves into its closed position. At the same time, appropriate measures are taken with respect to the longitudinal tensioning device 80 via connection lines, not shown here, so that the garment 1 is almost relaxed again. After this, the control device 70 controls the valves 61, 63 to open the tightening cylinders 35, 39, 43 and the tightening surfaces 34, 38, 42 to release the edge 4 of the garment 1. This allows the worker to remove the clothing 1.

FIG. 9 shows the longitudinal tensioning device 80 in detail. This longitudinal tensioning device 80 first consists of a guide tube 81 with an approximately rectangular cross section, which can be slid longitudinally along a piston rod 83 by means of a guide 84 and an anti-rotation element 82. It is located in The piston rod 83 is the longitudinal tension cylinder 8
The cylinder base 86 of the longitudinal tension cylinder 85 is fixed to the frame 31 in a non-rotatable manner. The piston rod 83 and the guide tube 81 are connected to the shoulder support 10. Vertical tension cylinder 8
When pressurized air is supplied to 5, the piston rod 83 moves out and pushes the shoulder support 10 upward together with the guide tube 81. 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 arranged in such a way that a predetermined tension force, adjustable in advance, is not exceeded during tensioning of the garment 1 or remains constant during the actual processing. ,It is configured.
