Description

The supporting and the orientation system that are used for the needle bent Sewing machines

Technical field

The present invention relates to the technical field of Sewing machines, particularly relate to through being usually used in the needle bent Sewing machines of Shoes Factory.

Background technology

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

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

Axle will drive through the 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 the sewing process.

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

Vibrate into suitable phase relation with pin outside, drive and keep sole, towards the direction opposite, for example be used for the thrust of needle support with advancing of pin from crochet device side so that push tabs.

When pin inserted in the tabs, longitudinal axis and crochet device be the amount that equates with the needle tracking step-length of being scheduled to of axial translation synchronously, thus the advancing of the material of having confirmed to sew.

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

Begin from initial machine, used the equipment of special interpolation to be used to obtain to be applicable to that the machine of special process operation changes.

In the scope of these variations, the arm of different shape is provided sometimes, so that the supporting of the material that must sew up and guiding device are fixed on this arm.

Arm links to each other with relevant base portion, and base portion is different at every turn, and the head of machine is fixed on this base portion with the 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 addition, also have italian patent No.1299967, this italian patent No.1299967 has introduced a kind of version, and it can be sewed the top of opening type to the relative bottom of pushing composite.

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

A little be higher than inlet point because leave, 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 (relevant with each possible version) various augmenting in the modification.

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

In some cases, for example when molded arm and base portion, these costs are owing to the batch machining of minimal amount needs to increase, and they possibly be kept at (according to running into what kind of sales order) in the 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) will make client when a kind of machine is transformed into another kind of machine, have problems, not even possibility (when production needs to change like this).

Summary of the invention

Therefore; The supporting and the orientation system that the purpose of this invention is to provide a kind of needle bent Sewing machines; Make it on uniform machinery, use a spot of simple change and be used to institute and might expand in the version, and all these is through being increased in the number of the common component in the various modification.
