Abstract

A shuttle emnbroidery machine has a drive beam which drives a drive for leading the shuttle shuttlecock. A guide part is fixed on the drive beam for guiding the shuttle. There is no friction between the guide part and the shuttle because the shuttle follows the guide part, so that the friction of the shuttle is largely reduced. The rear needle plate is unnecessary any more, but may be retained in the machine in the modification.

Description

Shuttle embroidery machine or binding-off machine

Technical field

The present invention relates to a kind of shuttle embroidery machine (Schiffchenstickmaschine) or binding-off machine (Steppmaschine), it has driver through axle (Treiberlineal) or like, is used to make at least one shuttle to come and go on the shuttle rail and moves.

Background technology

Embroidery machine carries out work according to two-wire system, just uses face line and shuttle line to carry out work, and wherein the face line becomes kink with the shuttle toe-in in each pin.The pin that is provided with pinprick passes cloth with the face line, and wherein this line forms coil when pin returns.Pass this coil comprising the shuttle that the shuttle line is arranged then.Usually embroidery machine or binding-off machine have a large amount of embroidery positions, and correspondingly have a large amount of pins and shuttle.So-called driver is used to make shuttle round mobile through axle or like.In the embroidery machine in modern times, driver is made of section bar through axle.This section bar has the hole, and for each embroidery position, a following driver nail (Treibernagel) and a last driver nail are inserted in these holes.By these driver nails, shuttle moves on the working face of the inclination of shuttle rail up and down.In binding-off machine, the shuttle rail is for being horizontally disposed with usually.No matter be in embroidery machine or in binding-off machine, the needle plate of front leads in the side that a side is used for shuttle, and the needle plate shuttle of back is used for the side guiding of shuttle at opposite side.

In recent years the speed of service of shuttle embroidery machine improves a lot.There has been per minute to embroider 600 pins or more machine.But different factors has hindered the further raising of machine rotational speed.The wearing and tearing that for example it is found that shuttle are strengthening.Be accelerated with 5 G because shuttle is the highest.The shuttle zone also produces high noise radiation when high speed.

Summary of the invention

Therefore task of the present invention is the wearing and tearing that prevent shuttle, and also reduces the noise from the shuttle zone as much as possible.

According to the present invention, in shuttle embroidery machine or binding-off machine, this task is by finishing with the guiding parts shuttle servo-actuated, that be used to guide shuttle in come and go the moving of shuttle.

Because this guiding parts and shuttle servo-actuated, so relative motion does not take place between shuttle and guiding parts.So wearing and tearing just do not appear in the side surface at shuttle.Surprisingly, use guiding parts also to make the reduction greatly of noise.

It is suitable on axle that guiding parts is fixed on driver.Yet described guiding parts also can move by additional drive unit.

Channeling conduct is suitable to shuttle in both sides.For this purpose, guiding parts surrounds shuttle in arc ground with a gap.But the fact shows, though guiding parts just at driver through that side directed shuttle of axle, wearing and tearing just have substantial degradation.This guiding has following advantage, can easily reequip existing machinery.In order to reequip, only need (block-foermig) guiding parts of bulk is installed in driver on axle.In order to guide shuttle laterally, guiding parts lobed (bombiert) contact surface is suitable.For guiding parts is fixed, this guiding parts can have the through hole that is used for bolt, is used for fixing at driver on axle.This guiding parts also has at least one axle journal suitably.It can be rabbeted in the hole of driver on axle.This structure of guiding parts allows to fix simply.

Description of drawings

Below with reference to accompanying drawing embodiments of the invention are described.Accompanying drawing illustrates:

Fig. 1: fixing shuttle box (Stoeckli) and the driver that moves up and down be through the side view of axle, have fixed thereon, be used for guiding parts that shuttle is led,

Fig. 2: according to the perspective view of the shuttle box of Fig. 1,

Fig. 3: observe the view of the shuttle box of Fig. 1 and Fig. 2 from behind, but omitted driver through axle, and wherein guiding parts and driver still as seen,

Fig. 4: the view of similar Fig. 2, however guiding parts has another kind of embodiment,

Fig. 5: from top view, it shows the shape of guiding parts,

Fig. 6: according to the perspective view of guide rail Fig. 4 and Fig. 5, that be used for shuttle and guiding parts.

The specific embodiment

The present invention is not only applicable to new machine, and can reequip existing machine with a spot of cost.Therefore Fig. 1 to Fig. 3 also discloses and how can existing machine have been reequiped.Shuttle box 11 has a plurality of shuttle rails 13 that are used for shuttle 15 in disclosed mode.Represent preceding needle plate with Reference numeral 17.Rear faller 19 no longer needs, but can be retained in the machine when repacking.The driver that moves up and down can be version arbitrarily through axle 21.Shown driver is EP 1 055 761 described versions through axle.Driver is made of a section bar 23 with hole through axle 21, and

driver nail

25,27 inserts in these holes.For each shuttle 15, on axle 21, be fixed with guiding parts 31 by means of bolt 29 at driver.In according to this embodiment of the invention, by this guiding parts 31, shuttle 15 is directed to through that side of axle at driver.Guiding parts 31 is configured to bulk, and preferably is made of plastics.For shuttle 15 being led laterally guiding parts 31 lobed contact surfaces.Guiding parts 31 has through hole 34 and two axle journals 37 that are used for bolt 29, and these two axle journals 37 are rabbeted driver in the hole 39 of axle 21, and make guiding parts 31 be in correct position with respect to shuttle 15.

When machine run, guiding parts 31 synchronously moves through axle 21 and driver 25,27 by driver, and these

drivers

25,27 drive shuttle 15, make and between shuttle 15 and guiding parts 31 relative motion do not take place.In described embodiment of the present invention, though shuttle 15 slides along needle plate 17 all the time in that side of pin.But practice shows, has been reduced the wearing and tearing of shuttle widely by 15 servo-actuated guiding partss 31 that guided in a side of shuttle.

Above mention, it is unnecessary to adopt described measure to make that the needle plate 19 of back becomes.The production cost of this rear faller is relatively more expensive.By comparison, the production cost of guiding parts 31 is low significantly.Therefore for new machine, the present invention also brings the reduction of cost.

Fig. 4 to Fig. 6 illustrates another embodiment of the invention.In this embodiment, shuttle 15 is directed in both sides by guiding parts 31 '.Shuttle 15 is directed to parts 31 ' and has some arc ground encirclement with gap a little.In others, the guiding parts 31 among guiding parts 31 ' and Fig. 1 and Fig. 3 is constructed in the same manner.It can be fixed on driver on axle 21 by bolt 29 (cannot see) too, and wherein axle journal 37 is rabbeted driver in the hole of axle 21.

Can draw following conclusion in sum:

The shuttle embroidery machine has driver through axle 21, and it makes shuttle 15 come and go the

driver

25,27 that moves with being used to.On axle 21, be fixed with guiding parts 31 at driver, be used to guide shuttle 15.Because guiding parts 31 and shuttle 15 servo-actuateds, thus between guiding parts 31 and shuttle, do not rub, thus reduced the wearing and tearing of shuttle widely.Rear faller 19 no longer needs, but it can be retained in the machine when repacking.
