Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an automatic sewing device for joining at least two cut pieces, particularly cut pieces of fibrous cloth. It is known that, for the purpose of It is placed horizontally on the table, including the needle, and the needle operates vertically.

This method has the disadvantage that the cut fabric pieces cannot be fed fully automatically into the stitching device. This is because the parts to be joined must always be brought to the suturing device manually, one on top of the other.

Additionally, a device for facilitating the handling of flexible materials using a vibrating table is known from East German Patent No. 233,755.

The cut pieces of cloth to be joined are stacked on top of each other by a worker so that the seam allowances at the beginning of the sewing are aligned. A suturing process then takes place.

Due to the vibration of the completely horizontal table, positioning of the cut fabric piece can now be realized with a small operating force.

This invention has the disadvantage that the worker must always overlap the cut pieces of cloth to be joined one above the other in area H at the beginning of sewing.

The object of the invention is to free up labor for loading material into automatic sewing machines.

The invention is based on at least the problem of developing a method for splicing and an automatic sewing device in which two cut fabric pieces from two stacks are fed into a sewing device fully automatically.

The present invention solves this problem by lifting the cut fabric pieces to be joined from separate stacks at a distance in front of the stitching device and placing them side by side on a work surface or by placing two or more cut fabric pieces at a distance from each other. This can be solved by stacking the suturing device on top of one another and positioning it in front of the suturing device. The positioning and guiding of the cut fabric pieces during the sewing process takes place freely on the board and on the work surface.

When the cut cloth pieces are fed in one on top of the other, this is done by combining the inclination of the plates and their vibrations.

The vibrations reduce the friction between the plates to a minimum.

This allows each cut fabric piece to be freely guided into the guide by means of the transport mechanism of the suturing device and the wire guide in front of the needle and at the edge of the plate, individually and one above the other. For cut fabric pieces that are easily handled, the oscillator is switched off or the plate is lowered during the sewing process.

In a variant in which the cut pieces are fed side by side into the stitching device, the edges of the two cut pieces to be joined are directed towards each other. The cut fabric pieces are here fed into the stitching device in a flat or adapted state to the working surface, side by side. During transport, the seams and the front edges of the suture area first slide upwards or downwards into a vertical position and come into contact just in front of the suturing device so that they are always in a vertical position.

In front of the stitching device, the front edge of the cut fabric piece in the seam area is positioned and thus fed into the stitching device.

The seam closure is carried out at right angles to the vertical seam, ie the seam is horizontal and perpendicular to the transport direction of the cut fabric piece.

In that case, the suture area, including the area where the stitches will be made later,
Their leading edges are brought into a vertical or near-vertical position.

The seam portions of both cut fabric pieces and the area where the seam will later be made are either oriented upwards or folded downwards.

The width of the sutures and their alignment in the area of their cut edges is achieved by their positioning in front of the suturing device.

The automatic sewing device includes two or more plates arranged one above the other or two parts arranged side by side on a vibrating table. The plate and the vibrating table are inclined in the transport direction as well as in a direction perpendicular to the transport direction. In their essential parts, they extend in front of the suturing device and reach behind it, viewed in the transport direction.

The plate is conventionally attached to the suturing device, also to the left of the needle. A component is connected to the edge of the plate facing the suturing device and extending in the transport direction. The plate and the parts are then inclined at the same angle of inclination in the direction of the suturing device. The plate exhibits another angle of inclination in the direction of the section, this angle of inclination being greater than that in the direction of the suturing device. The angle of inclination of the part direction is variable.

The lower plate in each case is wider than the upper plate on the side opposite the suturing device. On the part that protrudes under the board placed above, the cut fabric pieces coming from the stack are spread out.

For positioning the cut fabric pieces, a large part of the plate is arranged in the area in front of the stitching device, and only a small part is behind the stitching device. The parts connected to the plate are only in front of the suturing device. These parts are rigidly or articulatedly connected to the plate. The oscillation of the plate about the joint is effected, for example, by an actuating cylinder, not shown, so that the angle of inclination between the plate and the component can be varied. It is possible to lower the plate until it is flush with the part. In a variant of the embodiment, the plate and associated parts vibrate with the same amplitude. It is also possible to connect all plates and parts to the same oscillator. In another variant of implementation, the parts are loosely connected to the plate. In this case, the parts do not vibrate together.O On the lower part, an edge guide is mounted just before the suturing device, the number of its tongues matching the number of plates. The entry area of the tongue of the edge guide connects directly to the edge of the board. Direct entry of the suture into the edge guide is thereby achieved.

The upper part that connects to the board ends in front of the edge guide.

on board(s), on parts below, or on parts and board(s)
There is a guide perpendicular to the top installed vertically, and it has a horizontal limit at the top. For the lower plate the upper plate serves as a limit, and for the guides mounted on the parts there is a tongue which engages in a cavity in the upper plate or is provided above the upper plate. This is the upper limit. The guides are mounted variably on the plate and on the parts independently of each other. This arrangement can be varied individually for each cut fabric piece depending on the contour of the cut edge to be deflected when creating the seam. The cut edge of the cut fabric piece, by means of which a seam is to be subsequently provided, is guided along these guides during positioning and during the sewing process.

The number and arrangement of pieces per guide are determined according to the size and shape of the cut cloth piece in question.

In the region of the stitching device or behind it, a separate area for each cut fabric piece or a common area for both pieces is provided. The shape of these areas is adapted to the contour of the front edge of the respective cut cloth piece. These are swingably mounted so that they can be moved downwards after the cut fabric has been positioned under the fabric holder, but before the stitching begins, so that the guidance of the stitched cut fabric under the sewing device is not obstructed. It is designed to be released by swinging upward or sideways. Around these, around the edge guide device and around the guide, a separate sensor is assigned for each cut fabric piece. These sensors emit a signal when the respective edge of the respective cut cloth touches the perforation or guide perforation.

Only then can the joining process begin.

The angle of inclination of the plates relative to each other and in the direction of the parts is variable. This depends on the quality of the cut fabric pieces and their adhesion to the board with which they are connected.

In another variant, the two parts of the automatic iI-making device are arranged side by side. In one embodiment of this variant, both parts are provided centrally, viewed in the direction of transport, with two downwardly directed side guides which are connected to each vibrating body half.

In the area in front of the needle, the lateral guides are joined by their lower edges at the bottom, the latter extending into the area of the needle. In this embodiment, the cut fabric pieces to be spliced, with the cut edges forming the seam behind them, slide downwardly over the edges facing towards the center of the two parts of the vibrating table. In another embodiment, these cutting edges are raised upwards. For this purpose, both parts of the vibrating table have their edges pointing towards the center upwards, terminating there in two vertical guides.

In both embodiments, the stitching device is arranged behind the vibrating table, viewed in the direction of transport, and the needle position and direction of movement are both designed at right angles to the vertical stitching of the cut fabric. The horizontally arranged needles are located below the vibrating table in the area behind the side guides and above the vibrating table in the area behind the guides.

In both of the embodiments described above, it is possible to connect the two parts of the vibrating table rigidly to each other and to make them subordinate to a common oscillator as an integral vibrating system.

For this purpose, the side guides are rigidly connected to both parts of the vibrating table, or both guides are rigidly connected. Furthermore, it is also possible to vibrate both parts of the vibrating table separately. In this case, both parts loosely (engage with the side guides. The side guides and the lower part connected to them do not vibrate together in this case. When the guide is deformed upward, both parts engage with the side guides.) There is a distance in the guide that is slightly larger than the amplitude of the vibration system.

By tilting the vibrating table part in the direction of the stitching device, the transport of the cut fabric piece is realized beyond this.

In this connection, in front of the needle and at right angles to the direction of transport, there is a pivotable abutment for the leading edge of the cut fabric piece.

A sensor is attached to the front of the cut cloth piece for recognition.

Guides are provided on both parts of the vibrating table for guiding the cut fabric pieces to be spliced. These guides are arranged in a coordinate network on the table surface according to the shape of the cut cloth piece. A mirror-image arrangement on the image area of the table surface is then possible. If the shapes of the cut fabric pieces to be spliced are very different, individual placement of the guides on each part is necessary.

The guide ends at a distance in front of the suturing device,
The magnitude of the distance then depends on the cut fabric pieces to be spliced and the technique.

In the area in front of the suturing device, liquid flows directly into the guide or side guide.

The lateral guides are vertical and/or inclined. The slopes then become such that their lower edges are closer together than their upper edges. Advantageously, the slope is only on the side of the vibrating table facing away from the suturing device. Immediately in front of the suturing device, it extends perpendicular to the side guide. The parts of the vibrating table take the form of a curved surface and transition to the side guide. Again, the arc formed by the curved surface is larger in the area opposite the suturing device than in front of the suturing device. There the curved surface advantageously approaches one edge. With this technical solution, it is achieved that the cut edges of the cut fabric pieces gradually enter the side guides and come to be vertically aligned with one another directly in front of the needle. A septum is provided between the side guides and terminates just before the needle. By means of this partition, it is achieved that the cut fabric pieces do not stick to each other in the area of their cut edges during transfer to the stitching device. The side guide similarly ends in front of the needle. A puncture plate is connected to the side guide 23 on the opposite side from the needle. On the suture bag flIJ side, the distance of the side guide corresponds to the distance of the cloth presser.

The lower edges of the side guides are parallel or their distance is greater on the side opposite the bar tool.

Both parts of the vibrating table are preferably inclined in the direction of the lateral guide.

The guide ends before the needle and the puncture plate facing it. At the top, the guide is provided with a horizontal or slightly downwardly oriented section, the long edge of which is bent downward.

This region exists over the entire guide or only in the area in front of the suturing device.

In the case of separate vibrating table parts, the guides are arranged at a distance from each other, with a vertical bulkhead in the middle of this distance, terminating in front of the needle.

The minimum width at the bottom as well as at the top of the guide is slightly greater than twice the thickness of the cut fabric piece.

If there is a partition wall, the minimum width becomes thicker by the thickness of the partition wall.

Both parts of the vibrating table to which the guides connect are concavely bent. The curvature then decreases from the outer edge of the part towards the center and rises again towards the guide, so that the guide assumes a vertical or nearly vertical position. Here too, the parts are horizontal or inclined in the direction of the suturing device when viewed in the direction of transport.

The present invention will be explained in detail below with reference to Examples.

Example 1 In this example, two cut pieces of cloth are sewn together using a suturing device (1).
A variant of the solution is described with two diaphragms 2, 23 arranged one above the other, which are used for feeding.

In another implementation variant not described, it is also possible to arrange two or more diaphragms one above the other. With this solution, the associated edge guide 4 must be equipped with a number of tongues corresponding to the number of plates 2, 230.

On the side of the suturing device 1, viewed in the transport direction, there is essentially a section in front of the suturing device 1, and a small portion extending to the rear thereof,
Two diaphragms 2 and 23 are arranged one above the other and extend. The upper plate 2 is narrower than the lower plate 3, i.e., on the side opposite the stitching device 1, the lower plate 3 protrudes below the upper plate 2 by a portion necessary for placing the cut fabric piece 6 thereon.

Both plates 2, 23 are directed towards the suturing device 1 and towards the section 9.
10 to the edge guide 4. The inclination in the direction of suturing device l is then smaller than that in the direction of parts -9, 1, 0.

The greens 7.8 extending in the transport direction of the plates 2, 23 are parallel to each other. These edges 7.8 have their suturing devices 10
Parts 9, 10 are connected over the entire length in front, which are inclined only in the direction of the suturing device l.

This inclination corresponds to the inclination of the associated plates 2, 23 in this direction. The plates 2, 23 are each rigidly connected to the associated part 9.10, in this case the part 9.1o being connected to the plate 2,
23 or plates 2, 23 vibrate with the same amplitude as part 9.
10, in which case parts 9 and 10 do not vibrate together with the plate.

In another variant of the embodiment, the plates 2, 23 are connected to the part 9.10 via the joint 11, so that the inclination of the plates 2, 23 in the direction of the part 9.10 is variable; 23 is part 9
．． 10, yet only a common inclination of the direction of their suturing devices 1 is maintained.

Both plates 2, 23 are connected to the same oscillator, ie they vibrate with the same amplitude. It is also possible to use separate oscillators for each plate 2, 23.

An edge guide 4 is mounted on the part 10 just in front of the needle 12. The tongues 13 of the edge guide 4 connect directly with their guiding area to the edges 7.8 of the plates 2, 23. Parts 9
ends in front of the edge guide 4 when viewed in the transport direction. Boards 2 and 23 are used to guide the edges of the cut cloth pieces 6 to be spliced.
Above and/or perpendicularly to the part 10 a guide 14 formed as a pin or plate is mounted. 1 per guide
4 has an upper limit 15, and for the guide 14 mounted on plate 3, plate 2 serves as the upper limit. A tongue 16 is provided on the guide perforation 14 mounted on the part 10. The lower tongue 16 connects directly to the part 9 or engages in a cavity in the part 9.

The upper tongue 16 serves as the upper limit 15. 1 per guide
4 are all variable independently of each other. Their arrangement on the plates 2, 23 and on the part 10 depends on the shape of the cut fabric pieces 6 to be spliced.

So it does not have to be the same on both plates 2, 23.

The distance between the plates 2, 23 and their mutual inclination angle are variable depending on the properties of the cut cloth piece 6.

That is, the angle of inclination of each of the plates 2, 23 can be adjusted in both directions independently of each other.

In the area of the needle 12 or behind it, a joint 17 is installed, which is common to both cut pieces 6 or is individual for each cut piece 6 . These holes 17 are removable from their position after the suturing has begun. These are adapted to the contour of the front edge of the cut cloth pieces 6 to be spliced in each case, and are variable depending on this contour. The free movement of the cut fabric pieces 6 is ensured by the perforation 17.During their movement, both cut fabric pieces 6 overlap one another in the area where the stitching is to be started and are fed into the needle 12. is achieved.

A sensor 18 for each cut fabric piece 6 is assigned to the area 5, the guide area 14 and the area 17 of the edge guide 4I, from which a sensor 18 is assigned for each cut piece 6 of the edge guide 4I. A signal is emitted when the guide touches 15 to 17 or the corresponding guide 14.

The method of operation of this device is as follows.

The cut fabric pieces 6 to be spliced, coming from two stacks (not shown), are placed individually on each of the two plates 2, 23.

On the lower plate 3, the corresponding cut cloth piece 6 is placed on the part of the plate 3 that projects below the upper plate 2 on the side opposite to the seam f1. If plates 2, 23 are used, which are connected to parts 9.10 via joints 11, these are in a position below them when positioning the cut fabric piece 6. That is, it is flush with parts 9 and 10.

When both cut cloth pieces 6 are placed on the plates 2, 23, the plates 2, 23
is lifted by mechanical means (not shown) to the joint 1.
1 as the center, it swings toward part 9.1o and forms an inclination angle.

Subsequently, the plates 2, 23 are vibrated in both deformations.

During this time, the edge guide 4 is open.

Vibration of plates 2, 23 and their suturing devices tl to 1
In combination with the inclination in the direction of 7 and in the direction of the guide 14 to the edge guide 4, the cut fabric pieces 6 move independently of each other and freely movable towards the guide 17, the guide 15 and the guide 14. The front edges of both cut cloth pieces 6 touch the area 17,
The edges of both sides should be stitched along them 5
Also, when all the guides 14 come in contact with each other, a command is issued via the sensor 18, which lowers the cloth ≦ 6, causes the guides 17 to move out of that position by, for example, swinging them, and moves the edge mill inner tool 4 into its operation. Lower into posture.

If articulated plates 2, 23 are used, they are lowered at this point. But they continue to vibrate. When using plates 2 and 23 which cannot be lowered, the oscillator is switched off at this point depending on the circumstances, depending on the type of material.

Then close the seam. Due to the vibration of the plates 2 and 23 or their inclination, the edges to be joined are
And it is led in contact with 14 per article. When the seam is closed, a sensor (not shown) issues commands to uncut, lift the cloth presser, take out the material, release the edge guide 4, stop the oscillator, and swing back the hit 17.

Example 2 The cut cloth piece 6 is fed onto the vibrating table 19 of the suturing device 1. The suturing device 1 is located at the rear of the vibrating table 19, viewed in the direction of the conveying force. In this case, the direction of the movement force of the diagonal 12 is horizontal,
It is on duty at right angles to the vertically rising or hanging seams and in the direction of the transport force of the cut fabric piece 6. In this embodiment, there are two possible modifications to the basic implementation format.

In a first variant of the embodiment, the suturing device 1 is located on the lower blade of the vibrating table 19. Vibration table 190 parts added, 2
10 The opposing edges descend downward in a curved manner, and the vibration table 19
On the side opposite to the suturing device 1, the curved surface draws a large arc (.

This arc becomes smaller as it approaches the suturing device 1, and in front of the suturing device 1 it advances in the direction of the radius or O. The parts 21 gradually descend downward when viewed in the transport direction, and become vertically downward in front of the suturing device 1. Between the parts 20 and 210, a side guide (number of membranes) 22 is connected downward. The latter is directly part field,
21 or, in another embodiment, fixedly provided below the parts parts,
21 will be slightly covered. The lateral guide n can be mounted vertically or obliquely, with the lateral guide n being initially oblique and extending directly along the suturing device 1.
1 to move vertically. In a diagonal arrangement, their distance from each other is progressively smaller at the bottom than at the top.

The lateral guides n are parallel to each other at their lower edges. In a further embodiment, it is also possible to reduce these distances in the transport direction. Immediately in front of the suturing device 1, it is always equal to or smaller than the distance of the cloth presser.

The height of the bottom part can be adjusted. Its height corresponds to the desired width of the seam, including the area of the seam. Suturing device 1
In the range of and the range in front of it, the lower edge of the side guide A is firmly connected to the lower horizontal area. On the side opposite to the needle point, a puncture plate 5 is connected directly and fixedly to the side guide n. The lower area is slightly wider than twice the thickness of the cut cloth piece 6. When the side guides n are rigidly connected to the vibrating table 19, they vibrate together with the vibrating table 19, including the lower part. When there is no connection between the vibrating table 19 and the side guide η, they are rigidly mounted, including the lower part. The side guide n extends over the entire length of the vibrating table 19 and ends before the needle point.

Both parts 21 of the vibrating table 19 are inclined in the direction of the side guide B. In addition to this inclination there is another inclination in the direction of the suturing device 1. At this time, both parts are made into the same or different shapes depending on what kind of stitches are to be applied to what kind of cut cloth piece 6.

Both parts 20, 21 are provided with guides 14 which are variable in shape. Advantageously, these consist of cylindrical bottles and are variably positionable in a coordinate network on the table surface. The guide piece 14 is then installed according to the shape of the cut fabric piece 6. Their arrangement on parts m, 21 is either mirror image or individual. 14 per guide is in front of the suturing device 1,
It ends at a distance. In this area, they always lie directly in contact with the side guides 4. Their distance to the suturing device 1 depends on the size and shape of the cut cloth pieces 6, the width of the seam and the manufacturing technique.

Immediately before the suturing device 1 there is a swingable abutment 17 for the front edge of the cut fabric piece 6, which
A sensor 18 is attached thereto.

In a modification of the embodiment in which the suturing device 1 is arranged above the vibration table 19, both parts (1) are connected to each other, or both parts are placed at a distance slightly larger than the amplitude of the vibration system. There is.

The concave curvature of the part 210 rises from the outer edge down towards the center of the vibrating table 19 and transitions into a vertical or vertical guiding range.

In the case of an undivided vibrating table 19, the guide plate is extremely thin and at the same time serves as a partition wall n. In the divided vibrating table 19, separate partition walls n are provided between the guide holes. The septum n and the guide a terminate before the suturing device l. Above the guide hole and the partition wall d, a horizontal or slightly downwardly inclined collar is attached in the front area of the suturing device 1, and its long lateral edges are bent downward. The distance of the guide can be adjusted depending on the width of the suture.

Suturing device I! The transfer of the cut fabric piece 6 to 1.1 and its guidance takes place by the technical means already described.

The operation method of the automatic sewing device is as follows: The cut cloth pieces coming from the stack of cut cloth pieces, such as the tatami sleeve and the back sleeve, are placed side by side at a distance from each other and positioned at different positions in front of the sewing device & one side. be done.

There, the individualization of the stacks takes place. The cut fabric pieces 6 to be spliced are each placed individually on parts 20, 21 of the vibrating table 19. The edges which will later form the seam are opposite each other and abut the guide 14.

The leading edge at which the suturing is started is then in the area of the lateral guide n or guide a. The cut fabric piece 6 is transported in the direction of the stitching device 1 along the guide 14 by means of a feed element or by tilting the vibrating table 19. During transportation, cut cloth pieces 6
After these, the cut edges forming the suture part cross over the curved edge of the part 21, and in the area in front of the suturing device 1, the cut edges touch the lower area or the two-way guide. The suturing device 1 rises and slides until it comes into contact with its cut edges in the area in front of the suturing device 1.

In both variants, the subsequent suture portion and the area where the stitches are to be formed are in a vertical position in front of the suturing device 1. The partition n prevents the cut fabric pieces 6 from sticking to each other during transport.

The width of the suture is determined by the adjustable height of the lower wing. The leading edge is located in front of the suture portion ft1. It hits a swingable area 17 around which a sensor is provided. After the front edges are aligned, the hitter 17 is folded down and the front edge of the cut cloth piece 6 is caught by the cloth presser O. Begin the suturing process. The fabric retainer and needle 12 with associated puncture plate 5 are then operated horizontally. That is, they are rotated by 90 degrees from the normal suturing direction.

Individual feeding of two or more cut fabric pieces 6 combined with a free guide along the guide per 14 on an inclined diaphragm 2, 23 or a vibrating table 19 and a swingable per 1
7 allows for the first time a fully automatic material loading of the suturing device 1.
