Background technology

The prototype structure of supporting these machines has for example been, at the theme of the industrial invention patent of multiple countries (seeing US4848252).

Needle bent is bearing in the free end of arm, and this arm redial key is combined on the axle being longitudinally arranged in machine head.

Axle will drive by vibration alternating movement, for example, make pin move between two extreme positions along serpentine track, and the flexibility of this serpentine track and pin self is concentric.

Machine provides suitable supporting and guiding device, and this supporting and guiding device will limit the correct location of leather tabs in sewing process.

In outwards vibrating, pin, first through the edge of a tabs, then enters the edge of another tabs, from that side direction, leaves, to enter rotary hook system (being commonly referred to crochet device), this rotary hook system coordinates with pin, to form sewing needle tracking.

Vibrate into suitable phase relation with pin outside, drive and keep sole to press tabs, from crochet device side towards the direction contrary with advancing of pin, for example, for the thrust of needle support.

When pin inserts in tabs, longitudinal axis and the crochet device amount that synchronously axial translation equates with predetermined needle tracking step-length, thus determined advancing of the material that will sew.

Then the vibration of returning of pin is carried out in order, and it has determined itself and the disengagement of material, and can pass through axle-pin-crochet device group and reverse translation same amount, to make them be back to initial position.

From initial machine, the machine that is applicable to special process operation with the special equipment adding for obtaining changes.

In the scope of these variations, sometimes provide the arm of various shapes, to the supporting of the material that must sew up and guiding device are fixed on this arm.

Arm is connected to relevant base portion, and base portion is at every turn different, and the head of machine is fixed on this base portion with precalculated position.

These versions have also produced patent: for example, and italian patent No.1310413 and patent documentation WO96/17989, WO96/20305 and WO96/20306.

In this version, the head inclination of machine is adjusted ground and is installed, rather than vertical (due to arrange in advance, for its base portion); In this position, with together with the suitable constructions (it can vertically arrange the bottom that will sew) of supporting member and guiding device, in the pin inlet point in top and bottom leave a little between obtain rising track.

Because leave a little higher than inlet point, therefore in the side of bottom, form pin and leave angle, this is more favourable, therefore produces the better needle tracking of arranging.

Therefore, the structure of machine comprises a series of global facility and some peculiar part (version possible to each is relevant) in the various modification of augmenting.

Because peculiar part must be produced with finite population (with respect to global facility), therefore this peculiar part inevitably causes more expensive.

In some cases, for example, when molded arm and base portion, these costs are because the batch machining of minimal amount needs to increase, and they may be kept at (according to running into what kind of sales order) in warehouse for a long time sometimes.

Arm and base portion are included in element kit (this element kit is characterised in that the parts of special interpolation) and will make client have problems when a kind of machine is transformed into another kind of machine, not even possibility (when need of production changes like this).

Summary of the invention

Therefore, the object of this invention is to provide a kind of supporting and orientation system of needle bent Sewing machines, can on uniform machinery, use a small amount of simple change and be used to likely expand in version, and all these is by being increased in the number of the common component in various modification.
