Vorricntting for quilting or embroidery of strips of fabric or dp; l.

The invention relates to a device for quilting or embroidering fabric webs or the like. consisting of a main frame with a transverse

ί running bridge on which a needle holder in vertical

\ ' Direction is slidably arranged, wherein on the; Main frame a lower one movable in one direction

\ " Carriages and an upper carriage which can be moved perpendicular to it and which has guide rollers on one side and driven longitudinal guide rollers on the other side are provided.

In the classic devices, the pattern is generated by two movements of the fabric can be combined with the needle carrier, which is fixed. This is done by moving the tissue achieved in the longitudinal direction by the rotation of the driven longitudinal guide rollers, which on a Frame are arranged, which can be moved perpendicular to the movement of the fabric, what for example can be done by cams driven by a motor «

^: | However, such machines do not allow going back

moving the fabric and thus not the execution of patterns with closed edges.

To enable such a pattern, it has already been proposed to add a third type of movement, by placing the frame additionally parallel to the longitudinal movement

of the fabric is displaceable.

In the known device, which has two movements, these movements are activated by pressing electromagnetic clutches, which are driven by point stop counting apparatus, achieved, these Counting devices correspond in principle to the devices used in knitting machines, but differ from each other by the Differentiate them from each other by using a mechanical or hydraulic drive instead of a electric drive is used.

Such a device, "which by omitting. the cam represents a "significant improvement for any quilting or embroidery, however only to be used if straight paths • exist, because if the pattern is curvy or contains curved parts, the drive must also take place here via cams. The reason for this is that curvy roads require a number of many points to describe these curves, in contrast to straight stretches, which leads to the counting apparatus exceeding its capabilities. With such a It is also not possible for the machine to move backwards, so there are no patterns can be made with closed edges.

The present invention has set itself the task of avoiding the disadvantages of the known devices and to propose a machine in which no cams are required to control the various movements are not even if the pattern to be quilted or embroidered is provided with curves, with circles or other figures that are self-contained.

The invention consists in that for moving the lower carriage between this and the main frame a hydraulic motor and for moving the upper carriage between it and the lower carriage further hydraulic motor are arranged, wherein to drive the motors, a hydraulic generator, such as a pump or the like., Are provided during each • motor an electrically actuated valve of high

According to a further proposal of the invention, the procedure is that the valves with servomotors

Further features of the invention emerge from the following description of an exemplary embodiment in connection with the drawings and claims «

The device shown in Figure 1 consists of a main frame S on which a transverse Bridge Pt is arranged. On the bridge is a needle holder P with a plurality of needles Ag in provided displaceably in the vertical direction. The moving parts are made up of two suidsrliscsndeü VJasen susaM & en- namely, a lower one Carriage A, which runs on the main frame S transversely to the direction of movement of the fabric web, and an upper carriage B, which is arranged on the carriage A and is movable perpendicular to it. On the carriage B there are also the guide rollers Rd and those driven by a motor MH3 Longitudinal guide rollers G fastened

The directions of movement are also shown in FIG. 1, where y is the rotational movement of the Roles C represents, while ν and χ represent the movement of carriage A and wz the movement of carriage B. These directions of movement are also used in the further FIGS. 2, 3 and 5.

FIG. 2 shows the coordinates of a lock stitch, the stitch being from Pa to Pb. At the same time, the fabric must run lengthways ^! - be moved by the length L and in the transverse direction by the length T '", whereby these lengths L and T can be infinitely small, e.g. 0.5 mm or 0.1 mm.

Figure 3 shows a pattern that is followed by a Outline arises. The distance between the individual grooves is constant. You get

ζ.Β «the leaf-shaped shown in Figure 5 Structure in which the carriage A moves in the first quarter in the x-direction and the carriage B in the w-direction, while in the second quarter of the car A maintains its direction and the car B is now in z-direction is performed. In the third quarter, carriage A moves in direction v, while carriage B continues in the direction of ζ. Finally moves car A continues in the fourth quarter in direction v, while car B changes its direction and moves on now moved in direction w.

It follows that the sequence of movements and the individual movements must be carried out with great precision must be carried out as quickly as possible.

The three movements to which the fabric is subjected are advantageously achieved by hydraulic motors MH1 (transverse movement of carriage A), ΜΞ2 (longitudinal movement of carriage B) and MH3 (rotation of rollers G) - ₇ fed by a hydraulic generator, e.g. one Pump P, the motors driving the carriages A, B and the rollers C via chains, gears and the like. Electrically actuated valves V1, V2, V3 of high accuracy are built into the hydraulic circuit, which regulate the movement of the motors MH1, MH2, MH5. The valves V1, V2, V3 are in turn driven by servomotors ME1, ME2, ME3, ie a motor whose rotor causes an angular displacement with a constant and precise value. Each of these Stellsot-ore HEI _t H12 _? MEj is operated by a pulse generator GII ^ GI2, GI3 «

So it is proposed according to the present invention,

desired pattern is perforated, with the tape attached

show is provided. one showing the movement and its direction (positive or negative) and the other hatred of displacement (one step or several steps).

To make it easier to decipher the information contained on the tape, two types are used before. Key chosen, namely an alphabetic key that indicates the desired movement and their Sighting determined and a numerical key that relates to the value.

E.g.

Regarding car A:

after li-ifcs: ν - to the right: χ

Movement of carriage B:

forward: w - backward: ζ

Rotation of roles G:

Normal Shift Direction, Forward:. y

As already mentioned, only two simultaneous movements are necessary, so that it follows that deiß four lines of tape (see Figure 4) are needed for a lockstitch, namely line 1 relates refer to the direction of movement of car A, line 2 to the value of the displacement of car A, Line 3 on the direction of movement of carriage B and line 4 on the value of the movement of this Car

The band Bp, which moves forwards in the longitudinal direction, contains an additional one between two holes Sb (which correspond to stop devices) Row. During the hold time, the corrector gradually (or simultaneously) runs through the Lines 1, 2, 3 and 4- and the analyzer Co, with which the proofreader is provided, decodes these four lines and carries out the resulting from them Information dem. Electron brain too. The electrical brain "consists of the part mQ (or several) for Storage of the values while "for example the electronic brain mG1 for the displacement of the carriage A is responsible and the other electronic brains mG2 and mG3 control the further movements of the device.

The signals sent by the electronic brain (s) m ( come and those from mGi are distributed to a contactor 01, the other signals of the Electronic brains mG2 and iüG3 from further contactors 02 and 03 are recorded.

Each pulse generator, e.g. GH, is assigned a counter with two inputs, e.g. CG1, where "at the one input is used to trigger the values, while the other input triggers the desired movement.

Of course, the instruction is an appropriate one Generators only transmitted when the meter is ready for use, i.e. when a

It is possible to use numerous variations on this classification scheme, for example by interposed "brains" and transfer brains " be used so that the information first enters the counters (or only leaves them), when certain absolutely necessary conditions have been met. Such arrangements must also one or more transfer "monostables" step in between.
