Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a seam ironing device for ironing seams of fabric using steam, comprising a stand equipped with a blower and a stand fixed to the stand. A suctionable ironing beam is provided, in which case the ironing board of the ironing beam is a conveyor belt which circulates in the longitudinal direction of the ironing beam and whose direction of circulation can be controlled; an overbeam fixed to a stand; a shaped press body disposed on the overbeam that can be lowered toward the conveyor belt; and a shaped press body attached to the shaped press body that can be connected to a steam generator and can be heated. a steam chamber; a shaped press plate closing the lower side of the steam chamber and provided with a steam opening; a controllable fabric stitching device assigned to the free end of the overbeam; A receiving beam beyond which the ironing beam extends is provided.

BACKGROUND OF THE INVENTION A seam ironing device of this type is known, for example from US Pat. No. 3,107,447. This known seam ironing device has the task of significantly reducing the time required to iron seams, especially in conjunction with ironing operations during garment manufacturing.

As practice has shown, it is extremely difficult to automate this process, given the high demands on perfectly clean ironing of such fabric seams. These difficulties are based in particular on: This means that the fabrics to be treated differ over a very wide range with respect to their properties, which already makes it possible to change the seam area of the fabric to a greater or lesser extent between ironing and overbeaming, depending on the nature and thickness of the fabric. Good retraction is a prerequisite, however, it is not carried out satisfactorily in all cases.

In a seam ironing device of the above type, also known from GB 143 657, the fabric to be ironed is not run along the conveyor belt between the beams, but rather It is adapted to be retracted using a movable clamp fixed to the ironing beam, the clamp engaging the edge of the fabric.

Even if we ignore the fact that such drawing devices only allow relatively slow working cycle times and that the treated fabric has to be drawn out of the ironing beam again by hand, this known Ironing devices do not guarantee a satisfactory pulling of the fabric. This is because the fabric can very easily shift to one side when being drawn in along the ironing beam, so that satisfactory results cannot be obtained when ironing the seams.

OBJECT OF THE INVENTION It is therefore an object of the invention to always be able to draw the fabric between the ironing beam and the overbeam satisfactorily and quickly, regardless of the nature and thickness of the fabric, and to ensure that the ironing beam and overbeam can be drawn in between the ironing beam and the overbeam after the ironing operation has ended. To provide a seam ironing device capable of always satisfactorily and quickly removing fabric from the gap between the beam and the beam.

Means for Solving the Problem In order to solve this problem, the configuration of the present invention includes:
A controllable fabric edge holder is provided on the upper side of the conveyor belt and moves together with the conveyor belt during the seam ironing operation, the controllable fabric edge holder being a constituent unit having a base plate. is fixed to the conveyor belt by means of the substrate, and on the front side of the substrate there is arranged a fabric stopper edge oriented at right angles to the direction of movement of the conveyor belt, the fabric stopper edge contacting the fabric stopper edge being retracted. A controllable fabric clamping device is provided that descends from above to grip the edge of the fabric and engages the edge of the fabric stopper from above, the fabric clamping device being adapted to the rhythm of the work cycle. , the fabric edge in contact with the fabric stopper edge is tightened against the conveyor belt before the start of the fabric retraction movement of the conveyor belt;
This tight connection is adapted to be maintained beyond the receiving beam and through the fabric threading device at least during the fabric retraction movement between the ironing beam and the overbeam.

Functions and Effects of the Invention The present invention is based on the following recognition. In other words, a conveyor, which runs the fabric between the beams and again out of them, is combined with a fabric edge holder, which firmly holds the edge of the fabric introduced into the fabric threading device and moves together with the conveyor belt. In a very advantageous manner, the friction between the fabric and the fabric threading device, which varies in relation to the different static friction between the fabric and the conveyor belt surface as well as the fabric thickness, is reduced between the beams. The effect is that the precise guidance of the fabric is virtually no longer influenced. Furthermore, by additionally tightening the fabric edges during the travel movement between the beams, significantly higher travel speeds are possible, which shortens the working cycle accordingly.

Embodiment In an advantageous embodiment of the invention, the controllable fabric edge holder is fixed to the conveyor belt with a base plate using rivets.

The substrate also has ends on both sides that are bent upwardly at right angles to the direction of movement of the conveyor belt and project beyond the conveyor belt, and between the ends engages the edge of the fabric stopper from above. A mating fabric clamping device is pivotably mounted on a horizontal axis perpendicular to the direction of movement of the conveyor belt, the fabric clamping device having a rod that converts a vertical rotary movement into a linear horizontal movement. at least one said linear horizontal movement through the
Advantageously, one drive cylinder is connected, which drive cylinder is likewise held in the folded end region of the base plate. In this case, the fabric clamping device has at least two clamping fingers with L-shaped features, which clamp fingers only clamp the edge of the fabric being drawn in that is in contact with the edge of the fabric stopper. It is advantageous if things become tense.

Furthermore, in a further advantageous embodiment, the receiving beam is designed in a tubular manner, and on the upper side of the receiving beam there are a plurality of air openings oriented obliquely upwards towards the free end of the receiving beam. The tube interior of the receiving beam is connected to a compressed air generator via a controllable solenoid valve, and a lifting device for raising and lowering the shape press body together with its shape press plate is installed in the overboard. mounted on the beam and designed such that the lifting device occupies a first rest position above the conveyor belt during fabric retraction and a second rest position above the conveyor belt during fabric discharge following seam ironing; In this case, the distance between the forming press plate and the conveyor belt in the second rest position of the forming press body is set larger than in the first rest position, The ratio of the spacing between the forming press plate and the conveyor belt in the second rest position relative to the rest position is approximately 3/1, and the first of the forming press bodies
The distance between the shape press plate and the conveyor belt in the rest position is chosen to be of such a size that the widening of the fabric seam edges produced by the fabric stitching device is guaranteed throughout the fabric drawing. has been done. Configured in this way, the receiving beam and the lifting device not only achieve a rapid introduction of the fabric between the beams, but also additionally assist in the rapid release of the ironed fabric, and in this case Curved fabric seams are also considered.

In a further advantageous embodiment, the fabric threading device has a guide body which is fixed on the head side to a piston rod of a lifting cylinder held in the overbeam, and furthermore, A block-shaped seam folding body with a keel is arranged on the foot side, which seam folding body is movable relative to the guide body in the vertical direction in conjunction with an adjusting device, and the seam folding body The keel of the body has transitioned to a seam split sword,
A shoe-shaped fabric seam side guide is arranged on each side of the seam dividing sword, in which case the free end of the fabric seam side guide projects beyond the tip of the seam dividing sword, and the seam is separated on both sides. A fabric seam side guide held by the folding body is slidably guided along the seam folding body and the guide body, and the fabric seam side guide is held in a vertical direction of the seam folding body with respect to the guide body. Not only does this vertical movement occur in conjunction with the movement;
At the same time, an equal and opposite horizontal movement with respect to the seam-dividing sword is carried out, in which case the guide has a head plate which is rigidly connected to the piston rod of the lifting cylinder, and which head plates are mutually connected. It is connected to a foot plate via two parallel spacer bushes, in which a guide pin, on the lower end of which a seam folding body is fixed, is guided in the vertical direction; is capable of being lifted against the foot plate against the force of a pressing spring supported by the upper side of the seam folded body and the lower side of the foot plate, and furthermore, an elevating mechanism fixed to the upper end of the guide pin The head engages an eccentric rotatable about a horizontal axis, and each shoe-shaped fabric seam side guide is fixed via a connecting leg to a bearing plate, the bearing plate has in the region of its lower end a hole for receiving a transverse pin fixed to the seam folding body, and at its upper end transitions into a wedge head with a slope oriented towards the seam folding body. and
Furthermore, the wedge head of the bearing plate is additionally guided vertically via its slope in a correspondingly designed lateral wedge groove of the foot plate, so that the bearing plates of the two fabric seam side guides are centered relative to each other. The area is connected by a tension spring and is adapted to carry out a horizontal spreading movement against the force of the tension spring during vertical upward movement of the seam-folding body relative to the guide body. , during the vertical relative movement of the seam folding body with both fabric seam side guides, the horizontal relative movements of both fabric seam side guides caused thereby are of equal magnitude, and furthermore, the fabric seam threading On the front side of the device, an air nozzle is provided which is directed approximately forward and downward. Configured in this way, the fabric threading device not only can be quickly adapted to different fabric thicknesses, but also ensures a quick and always reliable threading of the fabric whose seams are being ironed.

The seam ironing device shown in FIG. 1 has a stand 1 with a stand base 2, which is provided with rollers 3, 4 for easy movement of the seam ironing device. ing. Stand 1 has entered stand head 5, and this stand head 5 has iron beam 6.
is fixed. The ironing beam 6 has a receiving beam 7 which extends it at its free end and is bent somewhat downwards, and an overbeam 8 which is arranged above the ironing beam 6.
It has The overbeam 8 has at its free end a fabric stitching device 9, which will be explained in detail later with reference to FIGS. A directed air nozzle 9a is assigned. Furthermore, the overbeam 8 is height adjustable in the stand head 5, as indicated by the double arrow. The overbeam 8 is open towards the bottom,
It has a forming press 10 equipped with an electric heating device, the steam chamber 11 opening towards the bottom of the forming press being closed off by a forming press plate 13. This type of press plate has steam openings 12 in the form of rows of holes. The heated molding press 10, including the steam chamber 11, is surrounded by a heat insulating layer 14 against the overbeam 8 and is moved around the piston rod 15 by means of a lifting device in the form of a crimping cylinder 16 fixed to the overbeam. It is disposed so as to be movable in the vertical direction via the overbeam 8.

The iron beam 6, which is configured as a suction trough, is provided with a conveyor belt 17, which conveys the material by means of a drive roller 18, a deflection roller 19, and a pressure roller 20 arranged close to the drive roller 18. It circulates in the longitudinal direction of the ironing beam 6 and forms an ironing board on the upper side of the ironing beam 6 in cooperation with a silicone rubber coating layer on the upper side of the ironing beam.

In its basic working position, the conveyor belt 17 is provided with a fabric edge holder 21 directly behind the fabric threading device 9, which moves together with the conveyor belt 17 when drawing in or finishing the fabric. , tensioning the fabric at its leading edge against the conveyor belt.

Shaped press body 10 in the area of overbeam 8
In order to supply steam to the steam chamber 11 of the stand head 5, a solenoid valve 22 is arranged at an appropriate height, and this solenoid valve is connected to a steam generator 24 via a hose conduit 23. . steam generator 2
4 need not be rigidly connected to the stand base 2 of the stand 1 as shown in FIG.
Can be installed freely. A blower 25 is rigidly connected to the stand 1 or to the stand base 2 and is connected to the suction trough of the ironing beam 6 via a conduit (not shown). FIG. 1 further shows a compressed air generator 30, which includes solenoid valves 22a,
Compressed air is supplied to the receiving beam 7 and to the fabric threading device 9 via 22b.

Furthermore, as shown in FIG. 1, a holding yoke 26 is pivotably arranged above the stand head 5, at the free end of which a control and control unit is provided in the area of the fabric threading device 9. The operating unit 27 is fixed. Control and operation unit 2
7 has a row of operating buttons 28 by means of which the desired cycle time for seam ironing can be adjusted. The control and operation unit 27 further includes a blower 25 and a solenoid valve 2.
2, 22a, 22b and the crimping cylinder 1 of the lifting device
6, the fabric threading device 9, the controllable fabric edge holder 21 and the drive for the conveyor belt 17.

A foot switch 29 is also provided on the floor next to the stand base 2 of the stand 1 for starting and interrupting the work cycle, which foot switch 29 is connected via a cable 29a passed through the stand 1 and the holding yoke 26. It is connected to a control and operation unit 27.

In the seam ironing station shown in FIG. 1, only one ironing beam/overbeam combination in stand 1 is shown.
However, it is advantageous for an optimal workplace configuration to arrange two beam combinations, side by side at a certain distance, on the stand 1, in which the fabrics to be ironed are supplied alternately by the worker. I understand. In this case, the steam generator 24, the blower 25 and the compressed air generator 30 can be assigned in common to both beam devices.

The receiving beam 7 shown in FIG. 1 is shown in cross-section in FIG. 2, and it can be clearly seen that the receiving beam 7 is constructed as a tube 7a, which has its free end. It ends in an arcuate closure at the end.

In order to keep the sliding friction in the receiving beam 7 as low as possible when removing the fabric to be ironed, the hollow chamber of the tube 7a is connected to a compressed air generator 30, which injects a plurality of air into the upper side of the tube. It has an opening 7b. These air openings 7b are oriented obliquely upwards towards the free end of the receiving beam 7, so that during removal of the fabric, an air stream exits through these air openings 7b towards the fabric.

As can be seen from the side view of fabric edge holder 21 shown in FIG. 3 and from the top view of fabric edge holder 21 shown in FIG. It has a substrate 31 which is made of aluminum.

The base plate 31 projects beyond the conveyor belt 17 on both sides and has upwardly bent ends in this area, to which a drive cylinder 35 is fixed in each case on both sides.

On the front side, the fabric edge holder 21 is assigned a fabric stop edge 33 oriented at right angles to the direction of movement of the conveyor belt 17, above which at least two clamping fingers are arranged. 34 is engaged. Clamp finger 3
4 is a yoke 34a that straddles the conveyor belt 17;
The fabric on which the seam to be ironed, which is fixed to and guided through the fabric threading device 9 to the fabric stopper edge 33, is to be ironed is clamped to the conveyor belt 17 at its edge. The fixing of the yoke 34a with the clamping fingers 34 is carried out by means of a drive cylinder 35, by means of which a linear horizontal movement is effected via a rod 36 connected to the end of the yoke 34a. , into a pivoting movement of the yoke 34a with the clamp finger 34 about the horizontal axis.

The fabric stop edge 33 is advantageously a component of the base plate 31, so that special fixing of the fabric stop edge 33 on the conveyor belt can be dispensed with.

The fabric threading device 9, shown in front, side and top view in FIGS. 5, 6 and 7, consists of a lifting cylinder 37 and a guide body 38 which receives the actual fabric threading device. It's on. In this case, the lifting cylinder 37 is rigidly connected to the guide body 38 on the underside via its piston rod 39. On the lower side, the lifting cylinder 37 transitions into a ring flange 37a, at which the lifting cylinder 37 engages in an opening 40 in the wall 41 of the overbeam 8 and is screwed there with the aid of an eye nut 42. .

The guide body 38 has a head plate 43 which is connected to a foot plate 46 via two mutually parallel spacer bushes 44, 45. The connection between the head plate 43 and the foot plate 46 via the spacer bushes 44, 45 is achieved by means of screws 47, as can be seen from the front view of the fabric threading device 9 shown in FIG. be exposed.

A block-shaped seam folding body 49 with a transverse pin 48 is located below the guide body 38 and is fixed to the lower end of the guide pin 51. The guide pin 51 is guided in a hole (not shown) provided in the foot plate 46, passes through the foot plate 46 at its upper end, and transitions into a lifting head 52 at this end. In this lifting head 52, the guide pin 51 is connected to an eccentric 53 which is part of an adjusting device 54. In this case, the eccentric 53 is fixed at the end of a horizontal shaft 55, which is rotatably held in a bearing mounting 56 fixed to the foot plate and which extends forward from the guide. The other protruding end has an adjustment button 55a. Rotation of the adjustment button 55a and therefore eccentric body 5
Depending on the shape of the eccentric disk, the seam folding body 49 can be adjusted in height continuously or stepwise against the pressure of the pressure spring 57 by the rotation of 3. The pressure spring 57 is supported on the guide pin 51 and is supported at its ends on the one hand above the seam folding body 49 and laterally on the underside of the foot plate 46.

The block-shaped folded seam body 49 transitions to a keel 50 on the front side, and this keel 5
0 further continues to the seam dividing sword 50a. Shoe-shaped fabric seam side guides 58 are provided on both sides of the seam dividing sword 50a. Each fabric seam side guide 58 is connected via a connecting leg 59 to a bearing plate 60 which is slidably guided along a transverse pin 48 in a hole 61 at its lower end. Furthermore, the bearing plate 60 has on its upper side a wedge head 62 whose downwardly extending inclined surface is oriented towards the seam folding body 49 . The two bearing plates 60 are guided with their wedge heads 62 on either side of the seam folding body 49 in vertically slidable manner in suitably designed lateral wedge grooves 63 of the foot plate 46. With this configuration, the seam folding body 49 using the adjusting device 54 can be
During the vertical relative movement of the fabric seam side guides 58, a horizontal expansion movement of the fabric seam side guides 58 simultaneously takes place.
If the inclined surfaces of the wedge heads 62 of the bearing plate 60 are configured to slide relative to each other in the wedge grooves 63 at an angle of 45°, the distance of the seam folding body 49 relative to the guide body 38 can be It is ensured that the ratio of changes always implements an equal longitudinal spacing change of the fabric seam side guides 58 relative to the seam dividing swords 50a. That is, the adjustment device 54
The fabric threading device 9 can be manually adapted to different fabric thicknesses as quickly as desired.

The opposite horizontal movement of the fabric seam side guides 58, carried out in connection with the vertical movement of the seam folding body 49 relative to the guide body 38, resists the force of the tension spring 64 which connects the two bearing plates 60 to each other. It is done as follows. In this case, the tension springs 64 are fixed on the support plate side by inserting the ends of the tension springs 64 into holes 65 in the center of the support plate 60.
This is achieved by being held by split pins 60 on the outside of the support plate 60, passing through them.

As can be seen from the plan view of the fabric seam threading device 9 in FIG. 7, the seam dividing sword 50a projects beyond the free end of the fabric seam side guide 58 with its sword tip, and is shown in FIG. As can be seen from the side view of the fabric stitching device 9, it has a front edge that slopes diagonally downward. Furthermore, the shoe-shaped fabric seam side guide 58 tapers in a wedge-like manner at its free end on the side of the seam dividing sword 50a. This makes it possible in a very advantageous manner to always easily and quickly thread the fabric seams of the fabric whose seams are being ironed by hand.

The fabric seam threading device is used during the threading of the fabric seam of the fabric whose seams are to be ironed, as well as during the drawing of the fabric between the ironing beam and the overbeam using the conveyor belt 17 after tightening in the fabric edge holder 21. 9 is a conveyor belt 17
, at a distance determined by the fabric thickness of the fabric being treated.

Furthermore, the shaping press 10 on the overbeam 8 still occupies its first rest position, in which the underside of the shaping press plate 13 of the shaping press is approximately 5.
It has a spacing of mm. This reliably prevents fabric seams that have been folded down during passage through the fabric stitching device 9 from standing up again during retraction between the beams. After carrying out the ironing operation, in which the shaping press 13 is lowered onto the fabric resting on the conveyor belt 17, the shaping press 10 is lifted into its second rest position, in which the shaping press 13 shape press plate 1
The lower side of 3 is located above the conveyor belt at a distance of approximately 15 mm. At the same time, and if necessary beforehand, the guide body 38, which forms the actual fabric threading device, is moved upwards by means of the lifting cylinder 37, so that the fabric threading device can be used to iron the seams of the fabric. will no longer prevent the release of At the same time, the second press body 10 is
Due to the rest position, the discharged ironed fabric can find a relatively large movement space between the beams. As already mentioned,
The ejection of the ironed fabric is assisted by the blowing air from the air opening 7b provided on the upper side of the receiving beam 7.

The seam ironing device according to the invention can be used wherever the seams of sewn fabric parts have to be ironed during the production of ready-made garments. The use of such a seam ironing device also serves not only for the economical production of ready-made garments, but also for always achieving equally good work results and thus quality assurance.
