Description
Technical field
The present invention relates to a kind of device that on double-lock type stitch sewing or embroidery machine, is used to change the looper thread shuttle as described in the preamble according to claim 1.
Background technology
Double-lock type stitch sewing machine has a shuttle usually, and it comprises that the shuttle tip and of clamping the needlework coil is installed on the inner casing in the shuttle, and inner casing has one by its bobbin case that holds.Wherein inner casing is provided with one and is concentric with the axle journal that the shuttle axis disposes, and when this axle journal inserts in the inner casing at bobbin case, embeds in the hollow cylinder that is arranged in the bobbin case, and bobbin case itself is loaded with and holds the shuttle that looper thread is got the raw materials ready.
For bobbin case being fixed on the axle journal of inner casing, axle journal is provided with recess in its free-ended zone, and a pin that is provided with thereon embeds in this recess in the bobbin case that inserts inner casing.This pin can overcome on bobbin case that spring force moves and for axle journal pass through have a perforate, its than axle journal diameter greater than an ormal weight.Pin therefore in the one final position fixedly bobbin case in case its from inner casing, come off and can from inner casing or shuttle, take out bobbin case in this final position by means of one that on bobbin case, swingingly be provided with and overcome another final position that spring force moves on to its disengagement bobbin case with catch that pin can be dynamically connected.Thereby for prevent in this position of pin and particularly not only during insertion but also in the taking-up process at bobbin case shuttle come off from bobbin case, be provided with the crooked flange that meets at right angles basically on pin, it inserts into the inner the chamber by the hole that is provided with and prevents that shuttle from coming off from bobbin case in the wall of bobbin case.
For the ease of the operation catch, its free end is bent some and is easier to catch in the back by operating personnel's ratio in order to take out bobbin case and be inserted in the inner casing from inner casing from bobbin case.
Since shuttle can only hold the looper thread of smaller length and therefore needs often change the taking-up of shuttle and relative bobbin case and insert again, the device that shuttle or bobbin case are changed in known being used to is with technique device imitation replacing shuttle by hand.
A kind of device that is used to change bobbin case has been described in JP 8-196 766.It has a hook by a mobile stool clamping, and this hook is rabbeted its catch in the back and given catch to be equivalent to the swing of manual movement, the relative position that catch constitutes on carriage in its terminal contact in order to take out bobbin case.Pin is realized a corresponding transverse movement whereby, throws off bobbin case and can be with shuttle by means of shifting out from inner casing by mobile carriage on predetermined guide rail thus.Wherein moving guide rail is designed so that its sealed ground of shape guide bracket and at first carries out one to be parallel to moving of shuttle axis location, transfer swing then to, and then one be tilted to down the motion that guides, in the holding device that its terminal point is handed to bobbin case below shuttle and the side is provided with.
Similarly this is realized a bobbin case that is equipped with the shuttle that fills up is inserted in the inner casing.
Therefore because bobbin case not only moves on to the process of holding device but also keeps by means of a hook force closure ground in the process that is moved on to by holding device in the shuttle at it from shuttle, therefore, hook must apply sizable pressure to catch in the whole duration of such motion.
Same in device according to US-PS 5 718 181, in order to grasp bobbin case, be provided with a hook of rabbeting its catch in the back, it is similar to according to the device of JP 8 196 766 catch is moved to holding device or moved on to by holding device in the process the shuttle at bobbin case from shuttle, is pressed on the corresponding block.Owing to constitute a protruding tongue simultaneously on this block, it is embedded in when catch is in its final position on the catch in the original groove that just is provided with, and the fractal sealed and part force closure ground, its above-mentioned motion process middle part that remains on of bobbin case is realized.
Shortcoming wherein is equally, and bobbin case is finished through a plurality of different motion stages to the transfer of shuttle from the shuttle to the holding device with by holding device, thereby this device also is complicated, and it is the manual bobbin case of changing of imitation equally in addition.
At last realize the replacing of bobbin case by DE-PS 1 206 713 known another devices in order to mechanical type in the shuttle that rotates in double-lock type stitch sewing machine is included in vertical plane, wherein bobbin case takes out from shuttle and a receiving positions of the holding device that leads along a guide rail that is parallel to the shuttle axis.Wherein be provided with an electromagnet slide plate that can therewith move with one and that be connected with electromagnet elasticity that is concentric with the removable setting of shuttle axis as bobbin changer apparatus.Electromagnet is gone out the deflection of bobbin case catch and is on the one hand thrown off the locking between bobbin case and the shuttle housing whereby and on the other hand shuttle is locked in the inside of bobbin case, thereby shuttle can not be from wherein coming off when extracting bobbin case subsequently.
To this, the principle that can take out among the DE-PS 1 206 713 also only is by means of the manual bobbin case of changing of mechanical device imitation.
Advised that about more early former undocumented DE 199 13 043 A1 the device of a same type is used for the bobbin case that double-lock type stitch sewing machine and adapts with it, wherein saved general afterwards lockplate and the bobbin case catch that utilized for its operation replaces the ring of the elasticity formation in the recess that two feet spring or inserts axle journal.Though simplified the structure of bobbin case whereby a little, wherein improved the construction expenditure of the motion of each holding element that is used for corresponding grabbing device.
