Description
Technical field
The present invention relates to a kind of device that on double-lock type stitch sewing or embroidery machine, is used for changing the shuttle that is used for looper thread.
Background technology
Double-lock type stitch sewing machine has a shuttle that has a shuttle tip of catching the sewing thread coil usually, and shuttle also has one and is bearing in end cover (Unterkapsel) in the shuttle together with the bobbin case that is held by this end cover.Here end cover be equipped with one with the draw pin of concentric settings of shuttle axle, it in bobbin case inserts the end cover time embedding be arranged in the hollow cylinder inside its, itself supports and holds the shuttle that looper thread is laid in.
On the draw pin that bobbin case is fixed on end cover, it is equipped with a kerf in the stub area that it stretches out from shuttle, and one holding screw that is arranged on above it embeds in this otch in the time of in bobbin case inserts end cover.Holding screw can overcome a spring force and move in bobbin case and have a hole, so that draw pin passes the big certain amount of the diameter of this boring ratio draw pin.Thus holding screw is fixed on the one terminal position, prevent that bobbin case from dropping out from end cover, but and can by means of a gyration be arranged in the bobbin case and overcome spring force and move on another terminal position that unclamps bobbin case with bobbin case lid that holding screw is connected movingly, bobbin case can take out from end cover or shuttle on this terminal position.Thereby in this position of holding screw and particularly both prevented when it takes out also when bobbin case is packed into that shuttle from dropping out from bobbin case, the one rectangular flange of bending basically is set on holding screw, it passes one and is arranged on groove on the bobbin case wall and inserts into the inner in the chamber and fixing shuttle, prevents that it from dropping out from bobbin case.
For the ease of the operation of bobbin case lid, its free end is bent away from bobbin case slightly, and can not be operated the person more easily and catch, so that bobbin case is taken out from end cover or pack into.
Because shuttle can only hold not oversize looper thread, therefore need often to change shuttle and the taking-up of the bobbin case that brings thus and reloading, the known device that is used for changing shuttle or bobbin case, they are with the manual replacing of technological means imitation shuttle.
In EP 0829565 A1 766, introduced a kind of device that is used for changing bobbin case, it has a hook by a movable bracket supports, this hook is caught its lid in order to take out bobbin case, and give its gyration corresponding to manual movement, fit at the correspondence position that gyration end lid and forms on support.Make holding screw do corresponding transverse movement thus, thereby unclamp bobbin case, and shift out from end cover by the support that can on the track of a regulation, move together with shuttle.Here movement locus designs like this, make support shape move sealedly, and at first be parallel to the motion of shuttle axis, it is transformed into gyration then, motion under then being tilted to, last bobbin case are handed to one and are arranged on the receiving system of side, shuttle below.
Similarly being equipped with the bobbin case of expiring shuttle packs in the end cover.Because thus not only its from shuttle when receiving system moves but also only fixing to force closure by hook from receiving system bobbin case when shuttle moves, it must cover at bobbin case duration of its motion whole and apply sizable thrust.
In by the device of US-PS 5718181, hook the hook that its bobbin case covers from behind in order to catch bobbin case also to be provided with one, similar with the device of pressing EP0829565, lid is pressed between moving period on the corresponding backstop to shuttle to receiving system or from it from shuttle at bobbin case.Because form a tongue piece simultaneously on this backstop, this tongue piece embeds when bobbin case lid is in its terminal position in the breach that is arranged on above it, and bobbin case is stated between moving period the sealed and part force closure ground of part shape thereon and fixed.
Here shortcoming is, bobbin case is transferred on the receiving system and transferred to above it from shuttle and is divided into many different motor segments in the shuttle and carries out, so device more complicated of manually changing of this same imitation bobbin case.
Therefore such scheme is hooking the bobbin case lid and part shape is sealed, be fitted in to the part force closure under the situation on the corresponding backstop from behind being only limited to aspect the manual replacing of imitation bobbin case by mechanical structure.
Be used on the double-lock type stitch sewing machine that has the shuttle that in vertical plane, rotates, mechanically carrying out the device of bobbin case or bobbin changer by DE-PS 1 206 713 known another kinds, wherein bobbin case takes out from shuttle along a track that is parallel to the shuttle axis, and moves to the receiving position of receiving system.Wherein as bobbin changer mechanism be provided with one can with the concentric electromagnet and a slide block that can move therewith and be connected that is provided with movably of shuttle axis with electromagnet elasticity.Electromagnet rotates the bobbin case lid, and cancels the locking between the bobbin case and the end cover on the one hand thus, on the other hand shuttle is locked in the bobbin case, and it can not dropped out from its inside when taking out bobbin case subsequently.Because the motion for slide block and electromagnet also additionally needs such mechanism except mechanical mechanism, so this scheme more complicated.
Last DE 199 13 043 A1 disclose a kind of device that is used for double-lock type stitch sewing machine of the same type and one and its bobbin case of matching, wherein cancelled sealing slide block commonly used up to now and operated needed bobbin case lid for it, and with a kind of two-arm spring or put into the doing of draw pin otch resilient ring replacement.Though the structure slightly simplified of bobbin case is made such bobbin case and no longer is applicable to its manual replacing thus.
Summary of the invention
Therefore the objective of the invention is, the device that is used for changing the bobbin case that holds shuttle that will be used for double-lock type stitch sewing machine improves as follows, make to guarantee bobbin case before its transfer movement and during caught reliably and fixed, and do not need to change bobbin case itself, make it both can by means of more changing device change and also can change by hand.
This purpose realizes by such mode, the operating mechanism that promptly is used for opening the bobbin case lid is made of a unlatching finger-type bar that can move between this bobbin case lid and bobbin case end face, and clamping device has two jaws on the longitudinal side boundary face that acts on the bobbin case lid that is opened, each jaw can with open the finger-type bar and be parallel to the orbiting motion stretch journey that the shuttle axis extends along one together, this distance is equivalent to pack into the degree of depth of shuttle of bobbin case at least.Because clamping device can act on the longitudinal side boundary face of opened bobbin case lid with two jaw on the next door near the bobbin case end face thus, and the bobbin case lid is fixed on its enable possition by the unlatching finger-type bar between this bobbin case lid and bobbin case end face, obtains a kind of scheme that the height functional reliability is provided of saving very much the space.
Reach scheme simple in structure by such method, promptly two jaws can be perpendicular to the adjustment part supporting of shuttle axial-movement by one, and the closing with opening movement of at least one in two jaws drawn by the motion of adjustment part.
If the motion of upper gripper jaw is drawn by the motion of adjustment part, the motion of another jaw is drawn by the motion of upper gripper jaw, and scheme can also further be simplified so.
This can realize by such mode in configuration aspects, and promptly be connected through the hinge respectively in order to produce two jaws of counter motion (pin-slotted hole connects) is hinged on one and is supported on the double armed lever of the equiarm on the support.
Just can be used in the double-lock type stitch sewing or embroidery machine with different big or small shuttles in order to make device of the present invention not do big change, vertical range between shuttle axis and two jaws can be by means of an adjustment element adjustment that acts on the adjustment part, and the centre position of two jaws can be complementary with the change in location of the shuttle axle of forcing to cause when the shuttle size changes thus.
If unlatching finger-type bar can be substantially perpendicular in the shuttle axis plane one move, especially revolution is just can reach the operation reliably of bobbin case lid so.
Draw by the motion of adjustment part if open the gyration of finger-type bar, so for realizing that this gyration is favourable.If adjustment part carries out the elevating movement of perpendicular layout and have the pin that stretches in the unlatching finger-type rod guidance approach rail road in order to produce the gyration of opening the finger-type bar, just can realize with simple method in configuration aspects so.
The bobbin case lid skids off from two jaws of clamping device during bobbin case is transported to receiving system or delivers to the replacing position therefrom from the replacing position in order to get rid of, and will open the finger-type rod lock and suit between bobbin case end face and bobbin case lid during carrying.This can realize that promptly guide rails has the zone of causing unlatching finger-type bar to stop by such method.
In order during opening finger-type bar working motion, to treat that rotating bobbin case covers the big as far as possible power that applies, and can be bearing on the bobbin case end face opening the finger-type bar simultaneously, open the finger-type bar and have a wedge shaped tip, wherein be arranged essentially parallel to the tracks of opening the finger-type bar and extend, and side and its tracks of bobbin case lid constitute an acute angle dorsad towards the side of bobbin case end face.Because the end face of bobbin case is not flat, but extending owing to the yarn pulling force is arch, have certain elasticity at least if open the finger-type bar in addition in its tip region, then is favourable.
