Definitions

  • the invention relates to a device for adjusting the interception device of a fabric presser of a sewing or embroidery machine.
  • Such an embroidery machine with a catching device for a presser is known from DE 3117140.
  • DE 3117140 With the interception device disclosed in DE 3117140 it is achieved that the presser no longer strikes the workpiece to be machined and thus the throat plate with the full force derived from the needle bar drive and transmitted via the intermediate spring, but is intercepted shortly before it hits , whereby at the same time a large part of the force inherent in the movement of the presser is absorbed before the presser is released with a certain time delay to carry out the remaining movement.
  • the interception device achieves considerable noise damping and the workpiece or the embroidery material is permanently damaged protected by the fabric printer.
  • the interception device consists essentially of a control cam which actuates an angle lever, one arm with an interception piece intercepting and releasing the accelerated fabric printer by a spring in the direction of the workpiece, so that the fabric printer hits the workpiece with braking.
  • a disadvantage of the interception device known from DE 3117140 is that, due to the rigid structure, the path of movement of the presser is the same for different workpiece thicknesses, so that with larger workpiece thicknesses the fabric printer strikes the surface of the workpiece with too great force, so that the advantages of Interception device are reduced.
  • DE 4324741 and DE 2938894 show interception devices for fabric printers, in which the path of movement of the fabric presser on the material thickness is possible.
  • a disadvantage of these devices is that they use complicated lever systems that are expensive in their Structure and susceptible to faults sin ⁇ . Due to the many moving parts, there are increased demands on the tolerances to be observed and the development of larvae is relatively large.
  • the object of the present invention is therefore to provide a device for setting a catch device of a fabric presser of a sewing machine, which is simple in its construction and enables adaptation to the most varied workpiece thicknesses.
  • the position of the mounting of the intercepting element which interacts directly with the fabric printer, is advantageously changed manually or automatically and held or locked in a specific position.
  • no additional elements are necessary, which must be arranged in the force transmission path between the interception element and the drive of the interception element.
  • the setting of the position of the support of the interception element which is advantageously an angle lever, should be freely movable and / or lockable in at least two positions or between two positions.
  • the bearing or the pivoting axis of the intercepting element can be pivoted about an axis, so that the position of the intercepting element e changes relative to the throat plate after the angle has been set.
  • the mounting of the interception element itself is mounted in a cylinder coaxially to its axis, the cylinder being mounted rotatably about its axis on the sewing or embroidery machine. If the cylinder is rotated, the storage, which, for. B. a bolt which is rotatably mounted in the cylinder coaxially to its axis around the axis, whereby the position of the bearing or the bearing pin to the throat plate changes.
  • the cylinder itself is by means of locking screws or a grid toothing, which, for. B. can be canceled against a spring force, locked in any angular position or in certain grid positions.
  • the angular adjustment of the rotatably mounted cylinder, which holds the mounting of the interception element can be carried out automatically by means of a drive.
  • the mounting of the interception element is not pivotally mounted about an axis, but is in particular parallel to the needle bar, for. B. lockable in an elongated hole in different positions.
  • the method of storage in the elongated hole can be carried out manually or automatically by means of a drive.
  • the material thickness in the vicinity of the presser below the presser is determined by means of a sensor and the position of the intercepting element is automatically adjusted by means of a drive.
  • Figure 1 is a side view of an embroidery head with an interception device according to the invention.
  • FIG. 3 shows an exploded view of the parts of an embroidery head relevant to the interception device
  • FIG. 4 shows an exploded view of an interception device according to the invention with an electric drive for automatically adjusting the mounting of the interception element;
  • FIG. 6 shows a multi-head embroidery machine with a central drive for the device according to the invention.
  • FIG. 1 shows a rare representation of the essential parts of the interception device.
  • At least one cam disk 5 is arranged on a shaft 4a which penetrates one embroidery head 4 or also other embroidery heads and which deflects a cam lever 12 which is pivotably mounted by means of the cam lever bearing 2 if the shaft 4a is rotated.
  • the free end of the one angle arm of the angle lever 10 carries a roller 9 which intercepts the presser 16, which is accelerated downwards by the spring F, and according to the movement of the angle lever 10, which is predetermined by the design of the guide curve of the cam plate 5 releases below.
  • the needle bar 17 is held by a guide 20 and is driven by the needle bar drive 15, which is not shown in FIG. 1.
  • the needle rod drive 15, like the angle lever 10, can be driven by the shaft 4a.
  • the position of the axis 10a of the angle lever 10 can be adjusted relative to the needle plate 19 and the embroidery base or workpiece 18 by rotating an eccentric bolt 7.
  • the eccentric bolt 7 is mounted in a bearing bush 8 and can be locked in any angular position by means of a locking screw 6 (FIG. 3).
  • the device has a bearing pin 2a, which is eccentric is arranged to an axis of rotation of part 2.
  • Part 2 lies with its cylindrical part 2b in one
  • the bearing pin 2a extends through the bore 3a and serves as a bearing for the cam lever 12.
  • the part 2 is by means of a plate 1 and one
  • a roller 14 or a ball bearing is mounted on a pin 13, which lies in the guide curve of the cam plate 5 and follows it when the cam plate 5 is rotated. Accordingly, the other arm and thus the angle lever 12 is pivoted.
  • FIG. 4 shows a further embodiment of the device according to the invention, the structure of the device essentially corresponding to that of the embodiment according to FIG. 3, but the eccentric bolt 7 being replaced by an eccentric bolt 21 which has a toothing (gear) at one end which is connected to a servomotor 22 via a toothed belt 23.
  • the eccentric bolt 21 and with it the bearing 10a of the angle lever 10 are automatically adjusted and held in the position.
  • FIGS. 5a and 5b show a further embodiment of the device according to FIG. 4, which has an additional sensor 24 which measures the material thickness or measures the distance between the surface of the workpiece 18 and the sensor 24.
  • the eccentric bolt 21 is rotated by means of the actuator 22 (not shown), as a result of which the pivot axis 10a of the angle lever 10 is pivoted relative to the throat plate 19.
  • the connecting rod 11 is used to compensate for the relative movements between the angle lever 10 and the cam lever 12 during the adjustment of either the cam lever 12 or the angle lever 10 by means of the respective adjusting device.
  • the mounting or the pivoting axis of the angle lever is not pivotably supported about an axis, but is moved linearly, manually or by means of a drive and locked in the required position. It is also conceivable that the bearing or the pivot axis can be moved and locked on any tracks.
  • FIG. 6 shows a multi-head embroidery machine with a central drive 24, which drives the eccentric bolts 21 of the individual embroidery heads 4 of the machine via a shaft 27 and toothed belt 23, as a result of which a height adjustment of the fabric presser can be carried out simultaneously for all embroidery heads. Since all embroidery heads mostly embroider identical embroidery patterns, it is sufficient to determine the distance from the surface of the embroidery material to the stitch plate only on one embroidery head or embroidery pattern in order to carry out the height adjustment for all embroidery heads at the same time based on the determined distance. In an embodiment, not shown, couplings are provided between the shaft 27 and the eccentric bolts 21, so that the height adjustment of certain embroidery heads 4 can optionally be or can be switched on.
