Definitions
- the invention relates to a filament winding housing according to the preamble of claim 1. Furthermore, the invention relates to a gripper with such a filament winding housing and a sewing machine with such a gripper.
- a filament winding housing of the type mentioned is known from the DE 10 2006 009 966 A1 , This filament winding housing has proven itself in use. Nevertheless, there is a constant need for a further improvement of the insertion behavior of such a filament winding housing.
- an adjustability of the inner diameter of the filament winding receiving space of the housing pot leads to the possibility that the filament winding housing adapts to the outer circumference of the filament winding. This reduces the tolerance requirements in the coordination of the inner diameter of the filament winding housing to the outer diameter of the filament winding, which is advantageous both in the production of the filament winding housing and in the production of the filament winding. It can be due to the adjustability of the inner diameter with reduced effort to bring about a situation in which the filament winding is fed enough from the filament winding receiving space and Therefore, it is frictionally connected to the housing pot. This ensures trouble-free operation of the sewing machine. If, as is usually the case, the filament winding is consumed from the inside to the outside, the frictional engagement is maintained until almost complete consumption of the filament winding.
- a biasing means according to claim 2 improves the frictional contact between the housing pot and the filament winding.
- the filament winding is then covered with a bias from the housing pot.
- a slot according to claim 3 may represent a particularly inexpensive executable variant of such a biasing means. It can be used elastic material properties of the material from which the housing pot is made.
- the housing pot can be made in particular of metal.
- a slot according to claim 4 leads to a particularly reproducible shapable elastic behavior in the inner diameter adjustment of the filament winding receiving space.
- a slot according to claim 5 leads to the possibility to ensure a sufficient inner diameter adjustment even with housing material with high modulus of elasticity.
- a Ausmünde-circumferential region according to claim 6 leads to a reduction of the manufacturing costs in the execution of the slot, since in this peripheral region of the housing pot jacket is carried out usually with relatively low strength.
- Slot widths according to claim 7 can be produced by conventional production methods. Since the slot only has to separate the two bottom wall sections adjoining it, the slot width is not limited to itself. The slot can therefore be produced, for example, by laser material processing or by wire erosion. In the context of laser material processing, e.g. a slot width of 50 microns or 100 microns can be achieved.
- a conical extension according to claim 8 facilitates the insertion of the thread winding.
- a sewing machine 1 has a base plate 2 with a stand 3 extending upward therefrom and an angled arm 4 (FIG. Fig. 1 ). The latter ends in a head 5.
- an arm shaft 6 is rotatably mounted, which drives a crank mechanism 7 with a thread lever 8 in the head 5.
- the crank drive 7 is drivingly connected to a displaceably mounted in the head 5 needle bar 9 in conjunction.
- the latter has a sewing needle 10 at its lower end.
- the sewing needle 10 can be moved up and down by the crank mechanism 7. In this case, the sewing needle 10 passes through a movement space.
- the sewing needle 10 leads in an eye from a spool 12 via a thread tensioning device and the thread lever 8 supplied needle thread 13th
- a support plate 16 On the base plate 2 is a with screws, which are guided through screw holes 14, 15, a support plate 16 is mounted ( Fig. 2 ), on which a workpiece 17 rests ( Fig. 1 ).
- the support plate 16 has a feed gate 18, which is designed for the passage of a feed dog 19.
- the feed dog 19 has a in the Fig. 1 illustrated needle hole 20 for the passage of the sewing needle 10.
- the feed dog 19 is driven by a arranged below the base plate 2 thrust and lifting gear.
- a gripper 21 which has a gripper body 22 with a gripper tip 23 ( Fig. 2 ).
- a thread winding housing 25 is rotatably mounted, in which a thread supply in the form of a thread winding 26 (see Fig. 7 to 10 ) is recorded.
- the gripper body 22 (FIG. Fig. 2 ) one Circumferential groove in which a bearing rib 24a ( Fig. 4 ) of the filament winding housing 25 is received.
- the filament winding 26 is also referred to as a bobbin.
- the filament winding 26 provides a lower thread 27 ready. This runs from the thread winding 26 to an outlet opening 28 (FIG. Fig. 2 ) on a thread path, which is described in detail below. From the outlet opening 28, the lower or looper thread 27 extends through the needle hole 20 and the opening 18 therethrough.
- the gripper body 22 is fixedly connected to a shaft which has a vertical axis 29 extending parallel to the needle bar 9 (cf. Fig. 1 ) having.
- This shaft is rotatably mounted in a bearing block 30 screwed to the base plate 2.
- a drive shaft 31 is also mounted, which is connected to a arranged in the interior of the bearing block 30 gear transmission.
- the drive shaft 31 is drivingly connected to the arm shaft 6 via a belt drive 32.
- the gripper 21 is therefore rotatable driven about a vertical axis. It is therefore a vertical gripper.
- the filament winding housing 25 has a housing pot 33 for receiving the yarn winding 26, which in different views in the 4 to 6 is shown. Furthermore, the filament winding housing 25 has a housing cover 34 for covering the filament winding 26 (FIG. Fig. 3 ). About a hinge connection, which specifies a pivot bearing with a horizontal pivot axis, the housing cover 34 is pivotally mounted on the housing pot 33 between a closed or working position, in the Fig. 10 is shown and a thread winding insertion adjustment, in the Fig. 7 to 9 is shown, pivotally.
- a filament winding receiving space 35 of the housing pot 33 is in an area between one in the 4 to 6 illustrated minimum inner diameter ID and a contrast enlarged inner diameter adjustable.
- the housing pot 33 has a slot 36 which extends from a housing pot jacket 37 into a bottom wall 38 of the housing pot 33 inside.
- the housing pot 33 and thus also the bottom wall 38 is round.
- the slot 36 extends radially, extending from one in the Fig. 4 Lower left portion of the bottom wall 38, which is completely divided by the slot 36, extends beyond the center 39 of the bottom wall 38 addition.
- the extending beyond the center 39 part of the slot 36 penetrates again about two-thirds of the radius of the bottom wall 38 between the center 39 and the housing pot shell 37. At this bottom wall side end of the slot 36 terminates with a rounding 40. In the region of the center 39 of the slot 36 penetrates a round passage opening 41, which represents a production auxiliary bore.
- the slot 36 terminates in the housing pot jacket 37 in a peripheral region between a housing stop 42 and an end portion 43 of the bearing rib 24a facing this housing stop 42.
- the slot 36 has a slot width perpendicular to its radial extent of 0.25 mm. Other slot widths are possible. In an alternative embodiment of the slot this has a practical slot width of 0, that is, after insertion of the slot, the two wall sections of the bottom wall 38 delimiting the slot abut each other. Other slot widths in the range between 0 and for example 0.5 mm are possible.
- the thread winding receiving space 35 opens out via a conical enlargement 44.
- the thread winding 26 is inserted into the thread winding housing 25 as follows ( Fig. 7 ): First, the filament winding 26 is placed and positioned on the conical extension 44 of the housing pot 33 with the housing cover 34 opened, that is, unfolded. Now pressure is exerted on the filament winding 26 in the direction of the bottom wall 38 of the filament winding housing 25 from above (see directional arrow 55). This pressure causes the filament winding 26, the housing pot shell 37 and thus the housing pot 33 increases slightly in its inner diameter, wherein the slot 36 extends in its extension to the housing pot jacket 37 out accordingly. The resulting inner diameter of the filament winding receiving space 35 is then slightly larger than the minimum inner diameter ID and corresponds to the outer diameter of the filament winding 26. Now, the filament winding 26 is fully inserted into the housing pot 33 from above until it comes into contact with the bottom wall 38 ( compare 8 and 9 ). Now, the lid 34 can be closed, so closed (see Fig. 10 ).
- the housing pot 33 is made of an elastic material and in the present embodiment of metal. This ensures that the housing pot 33 exerts a biasing force upon extension of the inner diameter of the filament winding accommodating space 35 onto the outer peripheral wall of the filament winding 26. This biasing force depends on the size of the inner diameter extension by the introduction of the thread winding 26, the length of the slot 36 and the thickness of the housing pot and the material parameters of the Genzousetopfmaterials. The over the in its inner diameter extended housing pot exerted on the filament winding 26 biasing force leads to a secure frictional engagement between the filament winding 26 and the housing pot 33. A relative rotation of the filament winding 26 to the housing pot 33 is thus prevented.
- the filament winding 26 is consumed from the inside to the outside, so that the frictional engagement between the outer circumference of the filament winding 26 and the inner wall of the filament winding receiving space 35 is maintained practically until complete consumption of the filament winding 26.

Abstract
Description
Die Erfindung betrifft ein Fadenwickelgehäuse nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen Greifer mit einem derartigen Fadenwickelgehäuse und eine Nähmaschine mit einem derartigen Greifer.The invention relates to a filament winding housing according to the preamble of
Ein Fadenwickelgehäuse der eingangs genannten Art ist bekannt aus der
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Fadenwickelgehäuse der eingangs genannten Art derart weiterzubilden, dass sich der Fadenwickel bei guter Betriebssicherheit und Verfügbarkeit der Nähmaschine einfach einlegen lässt.It is therefore an object of the present invention to develop a filament winding housing of the type mentioned in such a way that the filament winding can be easily insert with good reliability and availability of the sewing machine.
Diese Aufgabe ist erfindungsgemäß gelöst durch ein Fadenwickelgehäuse mit den im Anspruch 1 angegebenen Merkmalen.This object is achieved by a filament winding housing with the features specified in
Erfindungsgemäß wurde erkannt, dass eine Verstellbarkeit des Innendurchmessers des Fadenwickel-Aufnahmeraums des Gehäusetopfes zur Möglichkeit führt, dass sich das Fadenwickelgehäuse an den Außenumfang des Fadenwickels anpasst. Dies verringert die Toleranzanforderungen bei der Abstimmung des Innendurchmessers des Fadenwickelgehäuses auf den Außendurchmesser des Fadenwickels, was sowohl bei der Produktion des Fadenwickelgehäuses als auch bei der Produktion der Fadenwickel von Vorteil ist. Es lässt sich aufgrund der Verstellbarkeit des Innendurchmessers mit verringertem Aufwand eine Situation herbeiführen, bei der der Fadenwickel satt vom Fadenwickelaufnahmeraum aufgenommen ist und daher reibschlüssig mit dem Gehäusetopf verbunden ist. Dies stellt ein problemloses Betriebsverhalten der Nähmaschine sicher. Wenn, was in der Regel der Fall ist, der Fadenwickel von innen nach außen verbraucht wird, bleibt der Reibschluss bis nahezu beim vollständigen Verbrauch des Fadenwickels erhalten.According to the invention it has been recognized that an adjustability of the inner diameter of the filament winding receiving space of the housing pot leads to the possibility that the filament winding housing adapts to the outer circumference of the filament winding. This reduces the tolerance requirements in the coordination of the inner diameter of the filament winding housing to the outer diameter of the filament winding, which is advantageous both in the production of the filament winding housing and in the production of the filament winding. It can be due to the adjustability of the inner diameter with reduced effort to bring about a situation in which the filament winding is fed enough from the filament winding receiving space and Therefore, it is frictionally connected to the housing pot. This ensures trouble-free operation of the sewing machine. If, as is usually the case, the filament winding is consumed from the inside to the outside, the frictional engagement is maintained until almost complete consumption of the filament winding.
