Description

DEVICE ON SEWING OR EMBROIDERY MACHINES, FOR CHANGING THE BOBBIN FOR THE GRIPPER THREAD} for replacing bobbins for gripper threads

Such double backstitch-sewing machines typically have a gripper tip holding a needle thread hole and one gripper having a bobbin capsule received by the lower capsule and a lower capsule settled in the gripper. In this case, the lower capsule has a journal arranged coaxially to the axis of the gripper, which in the case of bobbin capsules inserted into the lower capsule is snapped into one hollow cylinder arranged in this capsule, the hollow cylinder Conveys the bobbin that accommodates the gripper chamber storage thereon.

To fix the bobbin capsule on the journal of the lower capsule, this journal has a cutting part in its free end, and in the case of the bobbin capsule inserted into the lower capsule, a paper latch formed therein is bitten. have. This paper bar is movable against the force of the spring in the bobbin capsule and has one opening for entry of the journal, the opening being a certain amount larger than the diameter of the journal. Now the jib restrains the bobbin capsule against its coming off the lower capsule at its one end position and is pivotally arranged on the bobbin capsule and is supported by the force of the spring by a lap movably coupled to the restraint The bobbin capsule can be brought to its other end position in response to free the bobbin capsule from which the bobbin capsule can be drawn from the lower capsule to the gripper. In order to prevent the bobbin from falling out of the bobbin capsule at the above-mentioned position of the paper latch and with it, especially during insertion and withdrawal of the bobbin capsule, the paper latch is provided with a generally curved bent portion. This protrudes into its inner space through a groove formed in the wall of the bobbin capsule and prevents the bobbin from falling out of the bobbin capsule.

To facilitate the operation of the flap its free end is bent slightly away from the bobbin capsule and can be gripped relatively easily by the user to pick up the bobbin capsule from the lower capsule and to introduce it into the lower capsule. have.

The bobbin can only accommodate the relatively small length of the gripper seal, so the frequent replacement of the bobbin combined with the extraction and reinsertion of the bobbin capsule requires manual replacement of the bobbin with technical means, Devices for the replacement of bobbins or bobbin capsules are known.

Devices of this kind are for example indicated in JP 8-196 766 and also in US PS 5 718 181.

The device according to JP 8-196 766 has one hook received by a movable carrier which holds its flap behind to pick up the bobbin capsule and gives it a turning motion corresponding to manual movement. At its end, the flap comes into contact with the opposite position formed in the carrier. This allows the restraint latches to perform a corresponding transverse motion, whereby the bobbin capsules are released and can be moved out of the lower capsule by a carrier which can be moved on a track given in advance with the bobbins. In this case, the motion trajectory is carried out by the carrier being guided appropriately to the mold, first of which is directed parallel to the axis of the gripper, which is then carried over to the pivoting movement and connected to this movement at an oblique downward direction. Followed by the movement, at its end the bobbin capsule is so shaped that it is carried over to the cassette arranged below and laterally of the gripper.

Similarly, bobbin capsules equipped with filled bobbins were placed into the lower capsule.

Since the bobbin capsules are thus only adequately supported by the hook during their movement from the gripper to the cassette and during the movement from the cassette to the gripper, this corresponds to the flaps on the entire lap of the above-described movement. You must exercise great pressure.

In the case of the above-described US-PS device, there is also a hook for holding his flap behind for holding the bobbin capsule, which is similar to the device according to JP 8-196766 to the cassette from the gripper to the cassette from the cassette. During the movement of the erotic bobbin capsule, the flap is pressed against the corresponding stopper. At the same time in the above stopper, in the case of the flap present in the end position, the tongue-like body gripped in the groove formed immediately in the flap is formed, so that the bobbin capsule is supported by the mold during the above-described movement, and the force is partially applied. It is made to suit.

Again here a number of different movements lead to the carryover of the bobbin capsules from the gripper to the cassette and from this to the gripper, as a result of which the device is also relatively complicated.

Thus, on the one hand, the task lies in improving this kind of device in a way that the gripping and supporting of the bobbin capsule on the one hand is simplified and the structural cost for the replacement of the bobbin is reduced on the other hand.

The present invention relates to a double bagstitch-sewing machine or knitting machine in order to replace the bobbin for the gripper yarn in accordance with the higher concept of claim 1.

19A-19D are schematic representations of the travel path of the bobbin capsule 101 from the gripper to the receiving location of the receiving device.

In the case of a device according to this kind, the problem is that the receiving position of the receiving device is directly on the side of the gripper and generally coaxial with the gripper, and the gripping device is located on the axis of the gripper between the position of the gripper and the holding device. It is solved by being able to move along a generally parallel orbit relative to it.

The arrangement according to the invention of the replacement position of the receiving device not only greatly simplifies the control of the bobbin capsule to be delivered, but rather leads the bobbin capsule from the receiving device to the gripper, or from the gripper to the receiving device. For this, an extremely short stroke was obtained, which was only slightly more than the width of the bobbin capsule as long as the distance between the bobbin capsule inserted in the receiving device and the gripper was reduced to the amount needed for entry of the needle thread. Big. This, on the one hand, significantly reduces the structural content for the delivery of the bobbin capsules, and on the other hand, a short stroke for the gripping device, which also leads to corresponding time savings, which means that the gripping device is replaced. There is a particularly strong effect from that point of view that the administration must be separated twice each time.

In this case it is clear that the teachings according to the invention are independent of the gripper structure and the assembly position in the sewing machine. It does not matter whether the rotating gripper is the problem or the so-called turning gripper is the problem. Likewise, it is irrelevant whether the gripper rotates about an axis parallel to the main axis of the sewing machine or about an axis laterally directed relative to the main axis. Even in the case of a sewing machine having a gripper rotating around a vertical axis, the teachings according to the invention can be applied.

A place-saving solution, such as having simple bobbins and at the same time simple transport, results when the receiving device is able to pivot about one axis parallel to and parallel to the gripper.

An alternative to this can be obtained when the receiving device pivots around one axis and this axis passes transversely to and crosses the axis of the gripper.

In this case it is advantageous when the receiving device can move in the vertical and / or horizontal direction.

Conventional dry bobbin capsules have a pivotable flap for gripping and processing, the pivoting motion of which is entrained by the cutting part of the journal of the lower capsule and causes the movement of the papermaking element formed as most of the supporters. This causes the bobbin capsule to be released to release it from the gripper.

On the one hand, the conventional flaps can be given up without replacement, and on the other hand, the solution of the embossing or tightening of the bobbin capsule during the carryover from the gripper to the replacement location of the receiving device is that the gripping device is on the skid. It has two supporting elements for bobbin capsules that can move parallel to the axis of the gripper, the first of which has a supporting finger, which is inserted into the groove formed in the bobbin capsule in the direction of motion of the gripping device. The indentable and second support element has one support nose portion, which is represented by being able to move transversely with respect to the long axis of the bobbin capsule while holding the paper slider. In this case it may be pivotally bearing on the first support element in order to obtain the lateral movement of the second support element.

Grooves for the first support element are installed on the bottom of the bobbin capsule and adjacent the grooves, the paper slider has a rear cutout, which is a bobbin capsule for both support elements when gripped from behind by the support nose of the second support element. This results in a relatively short stroke for the grasp of.

A solution that significantly simplifies the support element is a double-angular spring, in which the papermaking element is formed with two corners which are generally oriented parallel to one another, the first corner of which is in the locking position of the papermaking element in the lower capsule. The result is that it lies inside the cut of the journal and can be carried over to its release position by the gripping device.

Double-leg springs are also simultaneously bobbin when protruding into the receiving space of the bobbin capsule for the bobbin in the case of the double-angle springs in which the free ends of the legs of the double-foot spring are generally bent at right angles. It can be used to fix the bobbin on the large part of the capsule.

One variant of the first gripping device has a deployment device for double-angular springs with two fingers on top for releasing the bobbin capsule to take it out of the gripper while simultaneously preventing the bobbin from falling out of the bobbin capsule. These fingers can be moved between the legs of a double-foot spring by a skid that can be moved parallel to the axis of the gripper, where the angle of unlocking the bobbin capsule is additionally transverse to the trajectory of the skid. Can be.

The safety going past the excitation for the support of the bobbin capsule has a magnet with the gripping device carried by the skid, which can be obtained by interacting with the front side of the bobbin capsule.

On the one hand, the empty bobbin capsule can be easily removed from the receiving device and on the other hand the carrier is releasably combined with the capsule in order to be able to mount it back into the bobbin capsule with the filled bobbin. And it can be locked by quick closure. Thereby the receiving device can be equipped with a bobbin capsule having a bobbin refilled in a separate place irrespective of the sewing process at that time.

A particularly simple solution for driving a gripping device, which all require only one linear movement thereof, is provided when the gripping device can move from the side of the carrier away from the gripper to the gripper.

The receiving device has means for securing the bobbin capsule in the receiving device in position so that the bobbin capsule with the specially filled bobbin can be introduced into the gripper appropriately in position.

A particularly advantageous and also advantageously advantageous solution is that the means for fixing the bobbin capsules are generally oriented vertically and form two fins arranged spaced apart from each other, which protrude into the groove of the bobbin capsule. Wherein the spacing between the pins corresponds to the spacing of the fastening pins arranged in the lower capsule relative to the bobbin capsule and the recesses interacting with the fastening pins for their fixation in the bobbin capsule form the grooves for the pins of the receiving device. Obtained by doing.

Another fixability for bobbin capsules to the carrier is that it has a number of webs oriented generally parallel to its trajectory, where each of the webs has guide grooves for the restraint elements of the bobbin capsules, or If there are a plurality of sheaths arranged generally parallel to the trajectory and spaced apart from one another, this is indicated by having one guide groove each interacting with the restraining element of the bobbin capsule.

The present invention simplifies the gripping device for its transport from the gripper to the receiving device to the gripper from the gripper to the gripper, until no more parts are required for the support elements to move relative to each other. It is based on the challenges ahead.

The above object is to use bobbin capsules specially formed for this purpose, the gripping device has a number of supporting elements for the bobbin capsule, which can be moved parallel to the axis of the gripper on the skid and they are formed on the bottom of the bobbin capsule and It is solved by being able to enter into openings that are oriented generally parallel to their longitudinal axis, and move transversely with respect to the direction of motion of the gripping device for gripping the bobbin capsules in these openings.

In this case, the openings are formed as stepwise holes, which are advantageous if they join into the receiving space of the bobbin capsule for the bobbin.

The extremely simple possibility for the gripping of the bobbin capsules results from the fact that the supporting journals can pivot around each axis, either parallel or transverse to their longitudinal axis.

The fixing of the bobbin during the carryover of the bobbin capsule 101 from the gripper to the receiving device and from here to the gripper means that the supporting journals belong to at least one support spring for the bobbin, the support spring being the bobbins. Oriented generally parallel to, and in the case of supporting journals moved into the openings when they are caught in the gap formed in the housing of the bobbin capsule.

A structurally simple solution for the support spring and also for the movement of the support journal results from the support spring and the support journal being accommodated by a common carrier, which is coupled with the skid.

In order to be able to grip and move the bobbin capsules in both directions with the supporting journals, the supporting journals are provided with pressure elements adjacent to the entrainment, which are formed conical and the small diameter of the two-conical It is equal to or smaller than the small diameter of the phase holes and its large diameter is larger than the small diameter of the phase holes.

In terms of his construction and in terms of his movements and the start of his handling, paper sladers are made of a single ring which is formed by a single ring, which is placed inside a cutting section provided in the hollow journal of the bobbin capsule. It can be eliminated when it is arranged and elastically deformable in the radial direction.

In this case this is particularly simple if the elastic deformation of the papermaking element can be caused by the axial movement of the bobbin capsule which can be introduced by the support journal.

The conveying arms each have one receiving journal for the receipt of the bobbin capsules, so that the inside of the receiving device does not have a separate introduction of the movement for the papermaking element, and they There is one cut in the range, which cut corresponds to the cut in the journal of the lower capsule, where the diameter of the receiving journal corresponds to the diameter of the journal of the lower capsule.

In order to fix the bobbin or bobbin capsule received by the receiving journal, each receiving journal has at least one supporting spring extending in parallel to the receiving journal, and the supporting spring of the bobbin capsule pushed over the receiving journal. In the case there is an inheritance within one regard formed in the lanyard.

Further advantages and details of the invention emerge from the description of the embodiments shown in the figures.

1 shows a base plate 1 of a sewing machine as a dashed line, which has a gripper 3 which is circumferentially circumferentially around one horizontal axis 2, which gripper is known in the art. Work with a needle guiding (unmarked) the thread.

The gripper 3 has a lower capsule 4 used for receiving the bobbin capsule 5 in a conventional manner, and the bobbin capsule carries a bobbin 6 having a seal storage portion. Although the lower capsule 4 has no variation compared to the known embodiments of such lower capsules, FIG. 2 shows a front view of the lower capsule 4 in which its parts related to the invention are shown. The lower capsule (4) has a journal (7) arranged coaxially to the shaft (2) for fixing the bobbin capsule (5), which journal has a cutting portion (8) formed within the free end of its range. This cutting part interacts with the restraining element of the bobbin capsule 5 which will be described later. In its upper range there are two fixing pins 9 arranged spaced apart from each other on the inner side of the lower capsule 4, which fixing pins are inserted into the bobbin capsule 5 into the lower capsule 4. It protrudes into the groove 10 formed in this another range and fixes the bobbin capsule 5 in the radial direction.

The first embodiment of the bobbin capsule 5 shown in Figs. 3 and 4 is distinguished from conventional bobbin capsules as long as the ordinary flam which can be swung there first is omitted.

The bobbin capsule 11 according to the present invention has a housing 12 in which a hollow journal 13 is used, which is used for receiving the bobbin 6 in a known manner. On the front side of the bobbin capsule 11, a guide similar to the swallow tail for the papermaking element formed as the paper slider 14 is formed in a known manner, and this paper slider is transverse to the longitudinal axis of the bobbin capsule 11. It is arranged to be movable. This paper slider 14 has a stopper 15 as seen in FIGS. 3b and 4b which acts against a spring 16 arranged in the housing 12 and shows the paper slider 14. Press to the right with respect to 3 and 4. In the above-described position of the paper slider 14, the right end portion of the outer side of the bobbin capsule 11, which is bent at right angles and forms a hook-shaped nose portion 17, is present. The bobbin 6 is free from this.

The paper-making slider 14 further has a recess 18 formed in a step shape in the range of the left end. This results in a side of the paper slider 14-one bar 19 having a roughly half moon shape in plan view, which in the case of the bobbin capsule 11 is inserted into the lower capsule 4. It protrudes into the cutting part 8 of 7) and fixes the bobbin capsule 11 in the axial direction.

In particular, in the case of the bobbin capsule 11 taken out from the lower capsule 4, the screw acting as a stopper 21 is tightened into the paper slider 14 to limit the freedom of movement of the paper slider 14. The free end of the screw projects into the groove (not shown in detail) formed on the bottom of the housing 12 of the bobbin capsule 11.

In the release position of the bobbin capsule 11 shown in FIG. 4, the nose portion 17 of the paper slider 14 protrudes into the groove 20 formed in the housing 12 of the bobbin capsule 11 in a conventional manner. And the upper flange of the bobbin 6 is gripped to the bottom, as a result of which the latter is prevented from falling off the bobbin capsule (11).

As will be explained in further detail later, the bobbin capsule 11 is directly on the side of the paper slider 14 for the movement of the paper slider 14 from the locking position shown in FIG. 3 to the release position shown in FIG. 4. The gripping device being held is used. To this end, one groove 22 is formed in the left range of the paper slider 14 in relation to FIGS. 3 and 4, which has a groove 23 originally present in the bobbin capsule 11. Arranged and formed in a partially covered manner. Thus, the supporting element of the gripping device that is gripped while passing through both grooves 22 and 23 may come into contact with the right boundary of the groove 23 of the bobbin capsule 11. Furthermore, the groove 22 has a rear cutting portion 24 for the supporting element of the gripping device.

Finally, as can be seen from FIGS. 3b and 4b, the bobbin capsule 11 has one groove 25 in its upper range and the side interfaces of the grooves are inserted into the lower capsule 4. In the case of the capsule 11 it interacts with the fixing pins 9 of the lower capsule 9 and fixes the bobbin capsule 11 in the radial direction.

In the case of another embodiment of the bobbin capsule shown in FIGS. 5 and 6, the lateral conventional flaps are likewise eliminated. Compared with the first embodiment of the bobbin capsule 11, the paper slider 14 is also eliminated and replaced by the papermaking formed by the double corner springs.

The bobbin capsule 31 of the second embodiment thus has a double-angular spring 32 as described above as a papermaking element, one of which 33 passes generally horizontally with respect to FIG. 5 and with respect to the papermaking slider thus far. It is placed inside the upper guide. The free end of each of the corners 33 first runs obliquely downward and is curved at right angles to form the nose portion 34. In the locking position of the bobbin capsule 31, the nose portion 34 does not protrude through the groove 20 formed in the housing 12 of the bobbin capsule 31, so that the bobbin 6 is free.

The corner portion 33 of the double-angle spring 32 is coupled with a second corner portion 36 which passes through a web 35 and is about parallel to it, the second corner portion being bobbin capsules 31. In the locked position of the lower capsule 4 lies in the cutting section 8 of the journal 7, which causes the bobbin capsule 31 to be fixed in the axial direction. The corner portion 36-in relation to FIGS. 5B and 6B-is bent back in a ring to the right of its range, as a result of which the range 37 lies in the lower guide for the paper slider as ever. The section 33 and the range 37 of the section 36 thus run at about the same height within the guide to the paper slider 14 thus far, while the section 36 runs slightly above it from here. As can be seen in FIGS. 5 and 6, the range 37 is again bent at right angles in the horizontal plane and at the bottom of the web 35 the grooves of the housing 12 of the bobbin capsule 31 almost parallel to it. 23) and restrained there. The right range of the foot 33 is supported by one element of the gripping device and in this case the lower leg 36 of the double-foot spring 32 is pressed downwards by another element of the gripping device. 5b and 6b, the leg 36 moves out of the range of the cutting 8 of the journal 7, where the nose 34 of the leg 33 is simultaneously bobbin capsules. Moved to the housing 12 of the 31 and-in contact with the upper flange of the bobbin 6-while passing through the groove 20 in the housing 12, thereby debinding the bobbin capsule 31 In the case of), it is avoided that the bobbin 6 comes off from this.

7a and 7b show a first embodiment of the gripping apparatus 40 according to the invention, which interacts with the first embodiment of the bobbin capsule, ie with the bobbin capsule 11. The gripping device 40 has two support elements 41, 42, where the support element 41 is in accordance with a guide trajectory 44 which is oriented parallel to the axis 2 of the gripper 3. It is movable and is fixedly coupled with one skid 43 which is prevented from rotating on this. The support element 41 is provided with a support finger 45 which is in contact with the economic surface of the recess 23 of the housing 12 of the bobbin capsule 11 at its working position. The support element 42 is pivotally pivoted on the side of the support element 41 and has a support nose portion 46 which is the support of both support elements 41, 42. Viewed in the longitudinal direction-slightly backward relative to the supporting finger 45 and into their rear cutting portion 24 of the bobbin capsule 11 at their working position.

In addition to this the skid 43 carrying both of the support elements 41, 42 is driven by a frame 47 having a fixed location and may be formed as a cylinder or magnet 48. It is moved along the guide track 44 by the device. In this case the cylinder / magnet 48 grips the bent lever 49 bearing the frame 47 which is gripped on the side of the skid 43 via one pin / hole-engagement thereon. The skid moves against the force of the spring 50 and into the gripper 3 and thereby into the bobbin capsule 11. At the end of the longitudinal movement this support element 41 reaches its working position and is formed in the housing 12 of the bobbin capsule 11 while protruding through the groove 22 of the paper slider 14. Contact the interface of (23). This support nose portion 46 is in this case indeed likewise present in the recess 22 of the paper slider 14, but not yet in the range of its rear cut-out portion 24.

During the following pivoting movement of the support element 42, the support nose portion 46 is supported by the back cutting portion, which is held by the support element 42 and can be acted upon by a magnet carried by the support element 41. Guided within the scope of (24). In this case, the supporting nose portion 46 simultaneously contacts the interface of the groove 22 formed in the paper slider 14, as a result of which the paper slider 14 installs a lateral movement, thereby Is drawn out from the cutting portion 8 of the journal 7 of the lower capsule 4 of its bolt 19 and on the other hand the nose portion 17 of the paper slider 14 is recessed 20. It is guided to the inside of the housing 12 of the bobbin capsule 11 through. As a result, the bobbin 6 is prevented from falling off from the bobbin capsule 11 at the same time.

Bobbin through the support finger 45 of the support element 41 and the groove 22 formed in the paper slider 14 during the lateral movement of the paper slider 14 caused by the pivoting motion of the support nose 46. The bobbin capsule 11 resists forces laterally during the lateral movement of the paper slider 14 as it projects into the groove 23 provided in the housing 12 of the capsule 11 and contacts its interface. It is supported and the fitting of the bobbin capsule 11 in the journal 7 is avoided by this. The paper slider 14 gripped by both support elements 41, 42 thus stays in this position during the subsequent backward movement of the gripping device acted by the spring 50 to be relaxed. This bobbin capsule 11 is guided to a replacement site of the receiving device installed on the side of the gripper 3 directly along the track parallel to the axis 2 of the gripper 3 at the position described above and thereafter described. Is fixed.

8a and 8b show a second embodiment of the gripping apparatus 60 according to the invention, which interacts with the second embodiment of the bobbin capsule, i.e. the bobbin capsule 31 and the restraining thereof. The element is formed by a double-angular spring 32. The gripping device 60 has a deploying device 63 enclosing two fingers 61, 62 for unlocking the double-angular spring 32 which is likewise of the gripper 3. The skid 65 movable along the guide trajectory directed parallel to the axis 2 allows movement from the replacement location to the gripper and from there to the replacement location. The drive device for achieving the above-mentioned longitudinal motion of the skid 65 relative to the drive device of the first embodiment of the gripping device may be structurally the same, and therefore starts back to the drive device described above. According to this the skid 65 is also moved along the guide track 44 and by the cylinder or magnet 48 to the spring 50 in the manner described above.

The finger 61 is fixedly fixed to the skid 65 and has a step 66, while the finger 62 is pivotally confined to the skid 65 or to the finger 61. Fingers 61 to its step 66 act on each part 33 of double-angular spring 32. The finger 61 is also provided with actuation means that can be formed by, for example, a magnet 67 to pivot the finger 62 downward. This pivoting movement can be made against the force of the spring, which is not shown in detail, which then returns the finger 62 back to its initial position. This finger 62 has a compressive surface 68 which cooperates with the leg 36 of the double-leg spring 32. As can be seen from FIG. 8A and FIG. 8B, a magnet 69 is provided on the skid 65, and its anchor is directed parallel to the guide track 44.

The cylinder or magnet 48 moves the skid 65 to the gripper 3 against the force of the spring 50 to unlock the bobbin capsule 31. The finger 61 occupies one position at the action position of the deployment device, in which the step portion 66 is close to the lower side of the corner portion 33. The finger 62 is pivoted downwards and with its compression surface 68 presses the corner 36 downwards, where it (foot 36) is out from the cutting section 8 of the journal 7. It moves and frees the bobbin capsule 31 with it. At the same time, in addition to this, the nose portion 34 of the leg portion 33 is moved into the inside of the bobbin capsule 31 by the action of the force of the compression surface 68 on the leg portion 36. 34 contacts the flange of the bobbin 6 and thereby prevents the bobbin 6 from falling off the bobbin capsule 31. The anchor of the magnet 69 now moves towards the front axis side of the free bobbin capsule 31, as a result of which it is entrained during the subsequent return movement of the skid 43 and brought to the place of replacement.

The device according to the invention has a receiving device 70 for bobbin capsules, which is equipped with a carrier 71. This carrier is equipped with a number of receiving points 73 for the bobbin capsule and can pivot around the shaft 72. This shaft 72 may be arranged vertically or horizontally depending on the location of the corresponding sewing machine. It is important that the bobbin capsule occupy one position corresponding to its position in the gripper 3 at its replacement position. This means that the receiving points 73 and its supporting means for the bobbin capsule in the carrier 71 cause the longitudinal axis of the bobbin capsule to pass coaxially with respect to the axis 2 of the gripper 3 at its replacement position. And the bobbin capsules in the replacement position, as compared to their positions in the gripper 3, which do not interfere with the normal sewing process between the gripper 3 and the bobbin capsules and the carrier 71 at that time. This means that it is axially moved so far as to exist.

In the case of the embodiment shown in detail of the present invention, the shaft 72 of the receiving device 70 is arranged parallel to the shaft 2 of the gripper 3. The receiving device 70 is in this case received by a skid 74, which skid is arranged to be movable in a vertical direction along guide rods arranged on a mount not shown in more detail. 74). Since the skid 74 is also used for receiving the shaft 72, the receiving device 70 can rotate around the shaft 72 and if there is not enough place for this in the sewing machine, further rotation. You can move up and down for exercise. For driving the skid 74, a magnet 80 accommodated by a mount not shown in detail is used, which acts on it directly or via a stepped switch device.

In the case of the embodiment shown, the carrier 71 is equipped with four conveying arms 75 and the carrier thus has a total of four receiving points 73 for bobbin capsules. The carrier 71 pivots around the shaft 72 by 90 degrees at that time in a pulsating manner, as a result of which each of the receiving places 73 reaches the replacement position in a stepwise manner. Of course the carrier 71 also has four or more receiving points 73 and can be pulsated correspondingly.

9A-9C and also 10A-10C show the different possibilities of the special formation of receiving sites 73 for the bobbin capsule 11.

In the embodiment of the receiving places 73 according to FIGS. 9a and 10a the conveying arm 75 has a receiving journal 76, the diameter of which is generally the diameter of the journal 7 of the lower capsule 4. As a result, the bobbin capsule 11 is received on the receiving journal 76 under the same tolerance ratio as in the lower capsule 4. In the range protruding into the paper slider 14, the receiving journal 76 is formed with an eccentric protrusion 77, which protrudes into the groove 18 of the paper slider 14. As shown in FIG. The paper slider 14 thus maintains its position as far as the support elements 41, 42 to support finger 45 and the support nose portion 46 move out from their grooves 22, In this position, the nose portion 17 protrudes through the groove 20 in the housing 12 of the bobbin capsule 11 and grips one of the flanges of the bobbin 6 from below, and this is in the bobbin capsule 11. Hold firmly in Two pins 78 are provided for fixing the radial position of the bobbin capsule 11, which are received in the projection 79 of the carrier 71 and on the axis of the bobbin capsule 11. Faced vertically The spacing of its counterparts corresponds to the spacing opposite the fixing pins 9 of the lower capsule 4. The pins 78 protrude into the grooves 25 of the bobbin capsule 11, as a result of which they are fixed in the radially replaceable position in the same way as in the lower capsule 4.

In particular, as shown from FIG. 10A, the carrier arm 75 is present on the side of the groove 22 of the bobbin capsule 11, with the result that the supporting elements 41, 42 interfere with the bobbin capsule 11. Can be pulled onto the receiving journal 76 without receiving.

In the embodiment of the receiving places 73 according to FIGS. 9b and 10b, the return arm 75 has a receiving journal 81, the diameter of which is generally the diameter of the journal 7 of the lower capsule 4. Corresponds to The receiving journal 81 has one web 82 that is bent in place of the eccentric protrusion 77 and the web is oriented parallel to the trajectory of the skid 43 and the nose portion of the bobbin capsule ( 17 has a guide groove (83). Due to this, the paper slider 14 moves its holding device 40 fully onto the receiving journal 81 and the locking position of the bobbin 6 when it is released. Is maintained at. At the same time, the radial position of the bobbin capsule 11 is fixed by the nose portion 17 protruding into the guide groove 83. In particular, as shown from FIG. 10B, the carrier arm 75 is also present on the side of the groove 22 of the bobbin capsule 11, so that the supporting elements 41, 42 are the bobbin capsule 11. ) Can be attracted to the receiving journal 81 without being disturbed.

In the embodiment of the receiving places 73 according to FIGS. 9C and 10C, the carrier arm 75 is arranged with one sheath 84, the inner diameter of which generally corresponds to the outer diameter of the bobbin capsule 11. . The sheath 84 is open at its front side facing the gripper 3, and at the front side of the sheath far from the gripper 3, the sheath 84 has a bottom 85, and this bottom is gripped. An opening 86 for the passage of the support elements 41, 42 of the device 40 is used. The sheath 84 has a guide groove 83 for the nose portion 17 of the paper slider 14 on its inner side. Here too, the paper slider 14 is held in its position to lock the bobbin 6 when the gripping apparatus 40 is fully loaded with the bobbin capsule 11 into the covering 84 and the bobbin capsule 11 is released. do. At the same time, the radial position of the bobbin capsule 11 is fixed by the nose portion 17 protruding into the guide groove 87.

11A and 11B, the formation of receiving sites 73 for the bobbin capsule 31 inside the receiving device 70 is shown. Here too, the receiving journal 88 has a diameter corresponding to the diameter of the journal 7 of the lower capsule 4, and as a result, the bobbin capsule 31 has a lower capsule 4 Is received on the receiving journal 88 under the same tolerance ratio as shown in FIG.

This receiving journal 88 has a prism-shaped protrusion 89 at its end far from the gripper 3, the width of which generally corresponds to the width of the paper slider 14 of the bobbin capsule 11. As soon as the bobbin capsule 31 is pushed onto the receiving journal 88 by the fingers 61 and 62 of the gripping device 60, its protrusion 89 is formed in the bobbin capsule 31. Snapped into the guide for (14); For this reason, the bobbin capsule 31 is being fixed at the radial position. The protrusion part 34 of the leg part 33 also obstructs the return motion to the position in which the bobbin 6 releases its double-angular spring 32 which occupies the restraining position in this case. ) Stays in its position, which prevents the bobbin 6 from coming off from the bobbin capsule 31.

Drive device 90 having one magnet 91 in order to be able to rotate the receiving device 70 gradually around the axis 72 by an angular amount corresponding to the number of installed receiving places 73. 12 is provided. A slider 92 is connected to an anchor of the magnets 91, and the slider can move according to a guide trajectory formed in the horizontal range of the curved edge 93. This guide orbit may be formed by the gap 94 processed in the curved edge 93, and the lower end of the slider 92 is bitten into the gap. This slider 92 has one companion jaw 95 which interacts with the pins 96 of the index-disc 97 arranged on the axis 72 carrying the receiving device 70. In the embodiment shown, the magnet 91 carries out two working processes per switch step against the force of the spring 98 held at one end on the curved edge 93 and at the other end on the slider 92. The index-disc 97 is braked at that time after each switch step by the spring-loaded brakes 99 which are in the corresponding cutting section 100 in the index-disc 97.

For the following transition description, it begins with the situation indicated in FIG. 13, whereby four receiving places 73 of the receiving device 70 each having one bobbin capsule 11 are then filled. It is mounted with (6) and there is no bobbin capsule (11) in the gripper (3).

The paper slider 14 of the bobbin capsule 11 occupies the position which locks the bobbin 6 at that time. The receiving device 70 with the carrier 71 is located immediately to the side of the gripper 3, in which the bobbin is present in one of the journals 76, 81 or inside the sheath 84 at the replacement position. The axis of the capsule 11 is in line with the axis of the gripper 3 and the gripping device 40 with the supporting elements 41, 42-on the left side of the carrier 71-in relation to FIG. 13. exist. In the above situation, the bobbin 6 of all the bobbin capsules 11 is emptied by the preceding sewing processes, and the four carriers 71 are mounted on the outside of the sewing machine having four bobbin capsules 11. Appears when mounted with the filled bobbin (6).

Starting from here, the skid 43 has a support finger 45 of the support element 41 passing through the groove 22 in the support plate 14 on the guide track 44 thereof, and thus the groove 23 of the bobbin capsule 11. To the right, far enough to move within. By the pivoting motion of the subsequent support element 42 introduced by the magnets 51, its support nose portion 46 reaches the range of the rear cutting portion 24 of the paper slider 14. The thus retained bobbin capsules 11 into or to the lower capsule thereof in the gripper 3, leaving the corresponding receiving journal 76 or 81 or the sheath 84 during another longitudinal motion of the skid 43. It is pushed into (4) and in this case received by his journal (7). The nose portion 17 of this paper slider 14 is also always in its position of braking the bobbin 6; The support nose portion 46 is further present in its position allowing movement of the bobbin capsule 11 on the journal 7, the bobbin capsule 11 being completely in the gripper 3 or its lower capsule 4. Can be pushed in and occupy its sewing position.

Before starting the backward movement of the skid 43, the support nose portion 46 of the support element 42 is released by the magnets 51, as a result of which the rear cut-off portion in the paper slider 14 Exit from 24). The spring 16 arranged in the bobbin capsule 11 after the support elements 41, 42 have fallen out of the range of the paper making slider 14 is responsible for locking the paper slider 14 to the bobbin capsule 11. At the same time, the nose portion 17 of the paper slider 14 is moved to its position to release the bobbin 6. Again the skid 43 moves back to its initial position.

Now during the next sewing process the carrier 71 of the receiving device 70 stays in its position for so long until the bobbin 6 is worked empty. The receiving place 73 of the carrier 71 existing in this replacement position is thereby empty.

The skid 43 is newly moved to the gripper to the bobbin capsule 11 for the replacement of the bobbin capsule 11 carrying the empty processed bobbin. This support element 41 moves through the groove 22 in the paper slider 14 and into the groove 23 provided in the bottom of the bobbin capsule 11 and in this case makes contact with the lateral boundary thereof. do. The magnet 51 pivots the support element 42, as a result of which the support nose portion 46 is pivoted into the range of the back cut 24 in the paper slider 14. During the pivoting motion the support element 42 contacts the side boundary of the groove 22 and in this case pushes the paper slider 14 to its position releasing the journal 7; The nose portion 17 of the paper slider 14 is in this case guided to its rest position with respect to the bobbin 6 and prevents it from falling out of the bobbin capsule 11. The gripped bobbin capsule 11 can then be guided to an empty receiving site 73 which is in the replacement position of the carrier 71 during the now started reverse movement of the skid 43.

Support elements of the gripping apparatus 40 as long as its receiving places 73 for receiving the carriers 71 to bobbin capsules 11 are formed correspondingly to FIG. 9C and as a result have a coating 84. 41 and 42 move through the sheath 84 and in this case move the corresponding bobbin capsule 11 into the sheath 84. The nose portion 17 of the paper slider 14 present at its papermaking position for the bobbin 6 projects in this case into the grooves 87 of the sheath 84 and against torsion in the sheath 84. Fix the bobbin capsule (11). The inner diameter of the sheath 84 generally corresponds to the outer diameter of the bobbin capsule 11 and the paper slider 14 is immovable towards the right side-in relation to FIG. 9C-which is also a support element 41, 42. When) moves out of this, it also stays in its release position corresponding to the release of journal 7. The bobbin capsule 11 for conveying the bobbin 6, which is empty, has been replaced by the pivoting motion of the carrier 71 corresponding to the size of the number of receiving places 73 formed in the carrier 71. The bobbin capsule 11, which is moved out of the furnace and simultaneously conveys the filled bobbin 6, is brought to the replacement position.

Previously, the carrier 71 was equipped with one bobbin capsule 11 having the bobbins 6 filled therein when the bobbins 6 of all the bobbin capsules 11 were empty. It was started by being equipped with bobbin capsules 11 having bobbins replaced with or replaced with a bobbin refilled outside of the sewing machine. It is of course also possible to set the second replacement position with the gripping apparatus 40, 60 according to this invention with respect to the carrier 71. Such a second replacement position can be arranged immediately after the above-mentioned replacement position so that the bobbin capsule 11 has a bobbin that has been worked empty after leaving the first replacement position, and then immediately in the second replacement position. By the bobbin capsule 11, it can be equipped with a packed bobbin (6).

A third embodiment of a bobbin capsule and a gripping device adapted to it is shown in FIGS. 14 to 19.

In the case of another embodiment of the above described bobbin capsules, there is no conventional flap ever. Again, the paper slider of the first embodiment was eliminated and replaced by the papermaking element, which is arranged inside the bobbin capsule as opposed to the paper sliders of both the above-described embodiments.

The bobbin capsule 101 shown in FIGS. 14 and 15 has one housing 102 for receipt of a conventional bobbin 6, which is open at its front side facing the conventional lower capsule 4. And on its side farther from the lower capsule 4 is closed by the bottom face 103. The outer face of the bottom face 103 forms a slide face for each part of the needle thread hole in a conventional manner. The housing 102 of the bobbin capsule 101 has one hollow journal 104 in a conventional manner, the inner diameter of which corresponds to the diameter of the journal 7 of the lower capsule 4. In order to prevent the rotation of the bobbin capsule 101, the lower capsule 4 is provided with two fixing pins 9 arranged to be spaced apart from each other in a known manner, and the fixing pins have grooves formed around them. 10) protrude into and fix the bobbin capsule 101 in the radial direction. In order to fix the bobbin capsule 101 in its longitudinal direction, the lower capsule 4 has one journal 7, which is adapted to move the cutting section 8 in a conventional manner in the range of its free end. The cutting portion interacts with the papermaking element 105 of the bobbin capsule 101.

The papermaking element 105 is formed in a ring shape and may be formed by an O-ring 106 or by a spring ring 107 that is relatively easily deformable or deployable, which spring ring is a hollow journal. Received at the cutting portion 108 of 104 and its inner diameter is slightly smaller than the diameter of the journal 7. In this case the diameter of the cutting portion 108 is slightly larger than the outer diameter of the spring ring 107 or from the O-ring 106 of the elastic papermaking element 105. If the bobbin capsule 101 is pushed onto the journal 7 of the lower capsule 4, the papermaking element 105 is first deployed by the journal 7 and in this case is elastically deformed.

As soon as the papermaking element 105 is present in the range of the cutting portion 8 of the journal 7, the papermaking element 105 deforms to return to its original position and shape and the cutting portion of the journal 7. And the bobbin capsule 101 remains fixed in the axial direction.

As can be seen from FIGS. 14 and 15, the bottom face 103 is formed with all four stepped holes 109 oriented parallel to the longitudinal axis of the bobbin 6. Its large diameter is such that the four stepped holes 109 present in the range of the inner side of the bottom portion 103 are arranged at rectangular or forward corner points for reasons to be described later. The housing 102 is formed with two gaps 110 lying opposite to each other in the range of the bottom surface 103, into which the bobbin 6 is pulled out from the bobbin capsule 101. In the case of), the supporting spring of the holding device is bitten. On the side of the hollow journal 104, one hole 111 is formed in the bottom surface 103, which is rotated in the case of the bobbin capsule 101 which is pulled out from the lower capsule 4; Used for his fixation.

The description of the structure and mode of operation of still another embodiment of the gripping apparatus returns to the gripping apparatus 40 described earlier. In this case, the same parts as those of the gripping apparatus 40 described above of another embodiment of the gripping apparatus 120 are denoted by the same reference numerals as in the case of the gripping apparatus 40.

One carrier 121 is fixed to the skid 43 which is movable along the guide track 44 (FIGS. 16A and 16B), and these carriers are used for receiving four support journals 122 in all. The relative positions of the support journals 122 relative to each other and to the hollow journal 104 correspond to the arrangement and relative position of the stepped holes 109 relative to each other and to the hollow journal 104. . This ensures that when the skid 43 moves far enough in the direction of the gripper 3, the entire four support journals 122 are simultaneously locked into the four staircase holes 109. The support journals 122, which are generally parallel to each other at their initial positions, can rotate about one axis 123 in the carrier 121, respectively, which axes can be arranged horizontally or vertically. In the case of the embodiment shown, one axis 123 at that time, which may be arranged horizontally or vertically, may pivot. In the case of the embodiment shown, the axes 123 are arranged horizontally, with the result that the support journal 122 can pivot in a vertical plane. One magnet 125 is associated with each of the support journals 122 so as to allow the support journals 122 to pivot around the shaft 123. These magnets 125 are arranged in such a way that both support journals 122 adjacent to each other in one vertical plane can be moved away from each other or towards each other.

16A, 16B-At the bottom of the lower support journal 122, one support spring 124 is fixed to the carrier 121, the front end of which is bent down. In this case the arrangement of the support springs 124 in the carrier 121 means that the skids 43-in relation to FIGS. 16A and 16B-move the support springs 124 when they are moved far enough over the bobbin capsule 101. It is made so as to bite in the lower portion of the gap 110 of the bobbin capsule 101 and to prevent the bobbin from falling out of the bobbin capsule 101 against the rotation of the bobbin capsule 101. The tips of the support journal 122 are then each equipped with one projection 126 (FIG. 17), which has an annular surface which is used as the companion 127. The outer diameter of the entrainment 127 is slightly smaller than the diameter of the stepwise aperture 109 of the bobbin capsule 101, as a result of which the protrusion 126 easily enters into the aperture described above. In order to facilitate the introduction of the protruding portion 126 into the step-shaped hole 109 at that time, the range in front of it is formed in a slightly conical shape. The projection 126 is formed in a conical shape to be used as the pressure element 128 at a distance from the entrainment 127, the small diameter of which is slightly smaller than the small diameter of the step hole 109, as a result. The pressure element 128 only slightly moves into it.

18 shows the configuration of the receiving places 73 of the receiving device 70, which are suitable for the special formation of the bobbin capsule 101.

In this case, a receiving journal 130 is provided in the transfer arm 75, and its arrangement corresponds to the arrangement of the receiving journals 76, 81 shown in Figs. 9A and 9B. Thus, the receiving journal 130 has a diameter corresponding to the diameter of the journal 7 of the lower capsule (4). The receiving journal 130 has a cutting portion 131 in its end range facing the conveying arm 75, which cuts from the journal 7 of the lower capsule 4 to the cutting portion 8 thereon. Corresponds. Thus, the bobbin capsule 101 is received in the receiving journal 130 in the same manner as on the journal 7 of the lower capsule 4. In this case, in order to prevent the bobbin capsule 101 against the rotational movement in the receiving journal 130, a support spring 132 is fixed to the conveying arm 75 on the side of or above the receiving journal 130. , The free end thereof is easily bent and in the case of the bobbin capsule 101 pushed over the receiving journal 130 into the upper gap 110 in the housing 102 of the bobbin capsule 101. Handed down This also prevents the bobbin 6 from coming off from the bobbin capsule 101 or the bobbin capsule 101 from slipping off the receiving journal 130. In order to facilitate pushing the bobbin capsule 101 onto the receiving journal 130, its free end is provided with a conical projection 133. Finally, the conveying arm 75 may be provided with a pin 134 facing parallel to the receiving journal 130, which is the case of pushing the bobbin capsule 101 onto the receiving journal 130. The hole 111 is formed in the bottom surface 103 of the bobbin capsule 101.

19a to 19d are described for explanation of the method of operation of the third embodiment of the bobbin capsule 101 and of the corresponding support elements. In this case, the bobbin 6 existing in the gripper 3 is emptied and the receiving journal 130 of the receiving device 70 installed on the conveying arm 75 is in line with the axis of the gripper 3. And free from the bobbin capsule 101. The gripping device 120 is in its resting position lying on the left side of the transfer arm 75-in relation to FIG. 19A.

For receipt of the bobbin described above, the skid 43 is moved to the gripper 3 beyond the conveyance arm 75. The support journal 122 occupies its position in this case facing parallel to one another and by skid 43 the annular surface of the companion port 127 is the extent of the enlarged portion of the stepped holes 109. Into the stepwise holes 109 so far as to be present (FIG. 19B). The bottom face 103 of the bobbin capsule 101 is now present between the companion port 127 at that time and the pressure element 128 at the time of the support journal 122. In this case, the support spring 124 is gripped by the lower gap 110 of the housing 102 of the bobbin capsule 101 and the bobbin 6 is fixed during the axial movement occurring behind the bobbin capsule 101. .

In this position the support journal 122 is deployed by the magnets 125, as a result of which the entrainment 127 grips the base of the holes in stages (Fig. 19C).

During the now reversing motion of the skid 43, the resilient restraint element 105 formed by the O-ring 106 or the spring ring 107 is slightly outwardly by the backward motion of the support journal 122. Pushed towards and in this case reaches from the cutting 8 of the journal 7 of the lower capsule 4. The bobbin capsule 101 thus held by the support journal 122 is moved out of the lower capsule 4 and pushed onto the receiving journal 130 of the receiving device 70. In this case the elastically deformed papermaking element 105 is caught in the cutting portion 131 when it is on the opposite side of the cutting portion 131 of the receiving journal 130, so that the bobbin capsule 101 is lowered. It is fixed on the receiving journal 130 in the same manner as on the journal 7 of the capsule (4). The bobbin capsule 101 is also fixed in the radial direction because the pins provided on the conveying arm 75 are in this case passed into the holes 111 formed in the bottom surface of the bobbin capsule 101. In addition to this, the support spring 132 installed on the conveying arm 75 is caught into the bobbin capsule 101 through the upper gap 110 formed in the housing 102. As a result, the bobbin capsule 101 is on the one hand. This, too, is fixed radially and on the other hand also prevents the bobbin 6 from falling out.

After the support journals 122 have been returned to their parallel-position again, the gripping device 120 is brought back to its rest position by its skid 43, where the support journal 122 is also supported. 124 is also present outside the bobbin capsule 101.

If the bobbin capsule 101 equipped with the filled bobbin 6 should be brought from the receiving journal 130 to the gripper 3 to the lower capsule 4 by the gripping device 120, the skid 43 First, the gripper is so far away until there is an entrainment 127 in the interior of the receiving device 70 in the extended range of the stepwise holes 109 of the bobbin capsule 101 present on the receiving journal 130. The support journal 122 is moved in its parallel position in the direction of (3). As a result, the bottom surface 103 of the bobbin capsule 101 is again present between the companion port 127 and the pressure piece 128 of the support journal 122. Corresponding position corresponds to the position according to FIG. 19C. Starting from here, during another movement of the skid 43, the pressure pieces 128 of the support journal 122 cannot enter the stepwise holes 109 of the bobbin capsule 101, so the support journal ( 122 The expansion of itself may not be necessary. However, this means that the entrainment 127 does not have a coaxial position with respect to the stepwise holes 109 of the bobbin capsule 101 and thus the bobbin capsule 101 has a skid 43 into the gripper 3. It is purposeful to be so far away that it may not fall down from the support journal 122 during the motion of.

The present invention can be used in double backstitch sewing machines or knitting machines to replace bobbins for gripper yarns.
