Definitions

  • the invention relates to a thread clamping and cutting device arranged on a sewing machine, which has two resiliently interacting clamping disks and a knife with a knife edge arranged at an angle to the clamping plane of the disks.
  • a thread clamping and cutting device of this type is e.g. B. known from DE-U-74 05 640.
  • a first, only slightly protruding clamping disc is fixed in a recess of the machine, against which the second, overlying and thus inevitably strongly protruding clamping disc is pressed by means of a spring.
  • This second clamping disk is provided on a guide pin which axially penetrates the first, fixed clamping disk.
  • a clamping and cutting device of this type thus protrudes considerably beyond the wall surface of the machine at the installation point, so that its arrangement in the area of the working surface of the machine, i. H.
  • the present invention aims to provide a clamping and cutting device of the type mentioned, which in the most sensible place for its use, i. H. in the work surface of the machine, can be installed without the sewing work, d. H. to hinder the flow of material on the work surface, and which is also optimal in terms of clamping and cutting action.
  • the clamping and cutting device is characterized by a holding sleeve which is inserted at a distance from the needle insertion point into a recess in the working surface of the machine and is secured against rotation, the inner shaft part of which has an axially parallel edge bar with the knife edge and an outer clamping disk forming in The operative position is at least partially and at most partially out of the operative position connected in one piece above the working surface of the front part, while the inner clamping disk, which is axially movable between the shaft part and the front part along the edge web, is supported by a spring supported on the shaft part with its clamping surface facing outwards against the clamping surface facing inwards first clamping disc is pressed.
  • the clamping plane formed by the contact surfaces of the two clamping disks it is possible to arrange the clamping plane formed by the contact surfaces of the two clamping disks either directly, and only slightly, above the work surface or to lower it below this work surface when not in use. Since the inner clamping disc is moved further inwards by the inserted threads, while the outer clamping disc is fixed and the knife edge ends on this fixed disc, the outer clamping disc, the thickness of which is only determined by strength considerations, has to be above the working surface of the non-use position Protrude machine. In order to at least temporarily avoid this slight overlap of parts of the device in certain work steps, the holding sleeve can expediently be completely submerged in or under the working surface of the machine by applying slight pressure against the action of a spring from the working position of the device.
  • the outer end of the knife edge and thus the corresponding part of the clamping plane defined by the slightly inclined contact surface of the outer clamping disc advantageously lies in the plane of the working surface, while the insertion gap between the contact surfaces of the two clamp
  • the invention makes it possible to avoid this disadvantage by engaging on the holding bush which is axially displaceable in a guide bush by a driver which can be moved by an actuating element and which can be moved from a first working position, in which the outer clamping disc is flush with the working surface, to a second working position , which is the clamping plane created between the clamping disks at a predetermined distance above the work surface.
  • the driver is expedient a z. B. with one arm through a slot of the guide and holding bushing on the latter attacking double lever, which is limited pivotable about an axis parallel to the work surface. As such, this could bring the clamping disks into and out of engagement by manual operation of the driver.
  • the clamping and cutting device is practically only used when the presser foot is raised.
  • the lifting mechanism of the presser foot can be operated using a hand lever or a knee lever; in this case the driver can also be operatively connected to this hand lever or knee lever via a suitable linkage.
  • the driver can also be operatively connected to this hand lever or knee lever via a suitable linkage.
  • electrical or electromagnetic connections are also possible.
  • An arrangement has proven to be particularly advantageous in which the axis of the device is located in one and the needle insertion point of the machine in the other diagonal corner of a square in the feed direction of the sewing material behind and to the left of the insertion point and parallel to the feed axis.
  • the knife edge lies on the corner surface line farther away from the puncture point of the cross-section, which is expediently segment-shaped or crescent-shaped connecting web between the outer clamping disk and the shaft part of the holding sleeve.
  • the free arm cover plate forming the work surface A is 1
  • the needle plate having the needle insertion point x is 2
  • the feed dog acting through slots in this plate is 3 and its feed direction is indicated by a. If you think of a square y (FIG. 2) parallel to the edges of the cover plate 1, one corner of which is at the needle insertion point x and which extends in the feed direction a and left of the feed axis leading through the injection point x, then this leads to the cover plate 1 vertical axis b of the thread clamping and cutting device through the corner of this square y diagonally opposite the insertion point x.
  • a holding sleeve 4 of the clamping and cutting device is inserted into the recess of an inwardly projecting cover plate eye 1a.
  • the holding bushing 4 is provided with a segment-shaped recess 4b which extends over a circumferential angle of more than 100 °, so that an axially parallel edge crosspiece 4c with a cross-section and a relatively thin-walled end part 8 remain in the area of the working surface A.
  • the arrangement of the holding sleeve 4 in the cover plate eye 1a is such that the corner surface lines of the edge web 4c are in the plan on a line approximately parallel to the above-mentioned square diagonal (xb), ie the fall line of the inner surface 9 slightly inclined to the working surface A of the front part 8
  • the clamping disc runs approximately at right angles to this square diagonal.
  • the part of the axially parallel edge 10 of the edge web 4c which is distant from the puncture point x and which starts from the end part 8 is formed by an external bevel 10a to the cutting edge 10.
  • a second clamping disk 11 Arranged in the segment-shaped recess 4b of the holding bushing 4 is a second clamping disk 11 which is adapted to the recess cross section, the outer end face 12 of the inner surface 9 of the the first mentioned, formed by the front part 8 clamping disc is adapted.
  • the clamping disc 11 is firmly seated on a bolt 13 which, slightly offset to the axis b of the retaining bush 4, is guided in the shaft part 4a Jer retaining bush 4.
  • the clamping disc 11 is pressed against the end part 8 by a spring 14 supported on the shaft part 4a.
  • the two contact surfaces 9, 12 of the front part 8 and the clamping disk 11 form the clamping plane, which slopes slightly outwards from the outer end of the edge web 4c lying in the working surface plane and thus also from the knife edge 10 to a thread insertion gap 15, which there is created by relatively strong rounding of the clamping disc 11.
  • this insertion gap 15 is only slightly above the working surface A thanks to the slight inclination of the clamping plane, the upper and lower thread can be guided in the simplest manner approximately in the direction of the above-mentioned square diagonal in the feed direction a behind and around the device after the completion of a sewing operation, the Threads, as indicated in FIG. 2 at F, are guided by a slight pull at the insertion point 15 between the end part 8 and the clamping disk 11 and are cut off at the cutting edge 10.
  • the inwardly resilient clamping disk 11 clamps the thread parts F coming from the sewing point on the end part 8.
  • the diagonal distance xb a few, expediently about 5 cm, so that when the next sewing begins, there is a sufficient supply length of both threads F to allow the upper thread to come out of the eye of the needle and enter even when the needle is in an unfavorable position To prevent the looper thread from sliding back under the needle plate 2 when sewing starts again.
  • a major advantage of the clamping and cutting device described is not only that the cutting edge is nowhere exposed, but in particular that the outer clamping disk formed by the end part 8, which is also fixed during the clamping and cutting process, is only partially, and practically only protrudes beyond the work surface A on the side facing away from the sewing point, so that it cannot hinder the flow of material. If, on the other hand, this slight excess of the rounded end part 8, z. B. when using auxiliary devices lying on the work surface A, such as embroidery and darning frames, but could still have a disruptive effect, the holding bush 4 can be temporarily completely pressed into the work surface A by pressing on the end part 8 by means of such auxiliary devices against the action of the spring 7 sink. If desired, the clamping and cutting device could be locked in the lowered position by simple means, for example by means of a 2-stage design of the slot 6 and slight radial rotation of the holding bush 4.
  • a guide bush 21a is firmly inserted into a bore in the base plate 21.
  • a holding bushing 24 of the clamping and cutting device is arranged to be axially displaceable.
  • an inner shaft part 24a of the holding bush 24 is provided with a segment-shaped recess 24b which extends over a circumferential angle of more than 180 °, so that an axially parallel, parallel cross-section edge web 24c (analogous to the example according to FIGS.
  • a relatively thin-walled end part 28 remains on the outer end of the holding bush 24.
  • the starting from the end part 28 of the one, axially parallel edge 30 of the edge web 24c is z. B. formed by an outer bevel to the cutting edge.
  • a second clamping disk 31, which is adapted to the cross section of this recess, is arranged in the segment-shaped recess 24b of the holding bush 24.
  • the clamping disk 31 is firmly seated on a bolt 33 which is guided in the shaft part 24a in a slightly offset manner with respect to the axis of the holding bush.
  • the inner end part of the shaft part of the holding bush 24 is provided with a diametrical longitudinal slot 36.
  • the guide bushing 21a is also provided in the same plane with an approximately equally long longitudinal slot 37.
  • One arm 38a of a double lever 38 projects through these two longitudinal slots 36, 37 and is pivotably mounted on a pin 21 on an inner projection 21b of the base plate 21 in a plane perpendicular to the working surface A.
  • a head screw 39 is screwed into a threaded bore of the shaft part 24a, the tip of which rests against the lever arm 38a from below, which in turn projects upwards with minimal play against the unslotted part of the shaft part 24a.
  • the head of the screw 39 projects beyond the end edge of the guide bushing 21a and thus forms a safeguard against the axial pulling out of the holding bushing 24 outwards from the guide bushing 21a, even if the axial height of the slot 37 of the guide bushing 21a pulls out the holding bushing via allowable extent beyond.
  • a holding bracket 40 which is fixed to the base plate 21 and which engages under the lever arm 38.
  • This holding bracket 40 limits the possible pivoting movement of the lever arm 38a downwards, such that when the arm 38a rests on the holding bracket 40 (indicated by dashed lines in FIG. 7), the holding sleeve 24 moved downward by the arm 38a assumes a position in which is the top of the outer Clamping disk 28 lies in the plane of the work surface A.
  • the other arm 38b of the double lever 38 is provided with a curved path 41, in which a pin 43 fixed to a link 42 is guided.
  • the cam track 41 has a section 41a which runs concentrically with the axis 42a and a section 41b which controls the movement of the double lever 38.
  • the handlebar 42 can be pivoted on an inner console 21 d of the base plate 21 to an extent parallel to an axis 42 a parallel to the bolt 21 c.
  • This handlebar 42 is connected in a manner not shown to the lifting mechanism of the presser foot or its actuating element in such a way that when the presser foot is lifted (by actuating the element mentioned) the double lever 38 under the influence of the one interacting with the pin 43 approximately in the last third of its stroke Section 41b of the cam track 41 is pivoted into the position shown, in which the lever arm 38a pushes the holding bush 24 outward to such an extent that the clamping plane formed by the clamping disks 28, 31 and thus the thread insertion gap 35 are at a predetermined distance of a few mm the work surface A is. During such an interruption in the sewing work, the thread can thus be inserted and cut off between the clamping disks in a simple manner.
  • the double lever 38 which is also pivoted therewith, pushes the holding bush 24 with the clamping disks into the guide sleeve so far that the upper side of the clamping disk 28 is flush with the work surface A, as shown by dashed lines in FIG. 7 is shown. This prevents the device from passing over the work surface A, even if only slightly, but is annoying during the sewing work. It should be noted that the lifting of the presser foot due to the material thickness cannot cause the clamping and cutting device to overlap, since this does not affect the actuating element for lifting the presser foot and for simultaneously pivoting the double lever 38.
  • a pivotable double lever 38 is provided for axially displacing the holding bush 24, the arm 38a of which passes through the slotted shaft part of the guide bush and the holding bush.
  • the lever arm 38a could also be operatively connected to the holding bush 24 in another way.
  • another driver could also be provided for lifting and lowering the holding sleeve.
