Abstract

The embroidery machine, and especially a shuttle embroidery machine, has an individual thread guide (17) which can be moved in and out of action for each embroidery point (S1-S3). A switch unit simultaneously moves the needles (15) and the thread guides (17) in and out of action at an embroidery point (S1-S3), and also acts on a further unit such as a fabric drill (43), thread brake and/or thread monitor at the embroidery point (S1-S3). A coupling (51,53,69), at a unit (15,43,17) to be switched in and out of action, engages a straight edge (33,42,37) according to the position of the switch unit for one or more embroidery points (S1-S3), or is held by the switch unit in a disengaged position. A spring holds the couplings in the engaged position, to be moved against the spring action by the switch unit. The switch unit has a trough at a switch rod to secure the coupling away from the straight edge. The switch unit is operated pneumatically. The thread guide (17) is between two thread deflectors, and moves across the line of thread travel in a vertical movement. An eyelet (65) is at a thread guide lever (63), which is given a translatory movement by a swing shaft (61). The thread guide lever can be linked at an intermediate lever, as a swing coupling. The thread guide lever (63) is operated by a unit (37,35,25,11) which is engaged and disengaged. A common drive shaft (11) operates a number of units (15,17) at an embroidery point (S1-S3) with an additional and independent switch unit to switch needles (15) and/or thread guide (17) at a needle slide. The thread guide (17) for one embroidery point is operated independently of the thread guides (17) at the other embroidery points.

Description

The present invention relates to an embroidery machine, in particular Schifflistickmaschine, in which a Movable thread guide as one of the stitch-forming organs serves with a variety of individually switchable on and off Embroidery sites, according to the preamble of claim 1.

Embroidery machines come with a variety of embroidery points equipped in a row at the same distance, the so-called repeat are arranged. Each embroidery site points a number of stitch formation organs, namely especially needle and thread guide. Working with different embroidery repeats, e.g. every other needle, or with different colored yarns requires that certain Embroidery points switched on, but other embroidery points are switched off.

For example, Japanese Patent Application 04041763A discloses this Individual switching on and off of needle and drill the individual embroidery points.

In the embroidery machine according to EP-A 0 634 512, pro Two or more actuators are arranged in the embroidery location. With a The actuator is the needle, with a second actuator the drill can be switched off. By actuating a third actuator, the Thread brake levers are raised to the thread brake roller by uncouple the thread brake shaft. These three actuators will be through a switching element electrically, pneumatically or hydraulically activated or deactivated. Cannot be switched off are the presser, as well as large and small thread guides. The latter are in the usual way as poles for everyone Embroidery sites trained together. In an analogous way according to this document by other actuators also these others Tools of an embroidery location activated or deactivated become. The cited reference, however, shows no solution to.

A disadvantage of the disperse arrangement of different ones Actuators in the stitch-forming organs is that for everyone Stitch formation organ a separate line for controlling the Actuator must be relocated. These lines are also sensitive to vibrations, so that e.g. electrical Contacts loosened or loose cables worn through can.

EP-A-0 635 512 provides that a switching element needle, Thread brake and drill switches together. The thread ladder are however conventional, i.e. a big and a small thread guide extends the entire length the machine. The big one gives the stitch Thread guide releases the front thread to form a loop, to after the passage of the boat with the rear thread to pull the front thread through the loop and so the To complete stitch.

If an embroidery point is switched off, its needle remains stand, but the thread guide common to all embroidery sites loosens and tensions the front thread with every machine cycle. The thread of the stationary embroidery site is therefore through the Thread guide loosened around two hundred times a minute and excited again. This can lead to a long-term shutdown Embroidery point of the thread will be destroyed. There is also the Risk of the thread coming out of the thread clamp after cutting is pulled, so that a stitching on switching on again the embroidery site is prevented. Another disadvantage is that usual Z-line of the thread, which is a complex Threading by hand is required.

It is therefore an object of the invention to provide an embroidery machine create, which avoids these disadvantages. In particular, should the thread with a switched off embroidery through the Thread conductor neither broken nor out of the thread clamp can be pulled. Furthermore, the thread should also can be automatically threaded into the thread guide.

According to the invention, this is due to the features of Characteristic of claim 1 achieved. That the respective An individual embroidery location that can be switched on and off Thread guide has the advantage that when stopping the thread guide is stopped at an embroidery site. The Thread from this embroidery site is neither destroyed nor from the Anchoring pulled in the thread clamp, because at not everybody will turn off the embroidery point Machine cycle relaxed and tense again.

The embroidery machine advantageously has a switching element in order to Simultaneously with the needle the thread guide of an embroidery site on or off. A separate switch off and Switching on the thread guide and thus the possibility of the thread guide when the embroidery point is switched off wrongly not switching off can be avoided become. The switching element advantageously switches at the same time at least one other organ, e.g. Drill, thread roller and / or thread monitor, the corresponding embroidery site on or off. Preferably, all organs are with the switching element the embroidery location is switched on or off at the same time.

The embroidery machine advantageously has one Coupling member on the on and off switchable organs, such as Needle, drill and thread guide depending on the position of the switching element in engagement with one over several Ruler running through the embroidery points or through the switching element in a position that does not interfere with the ruler is held. As a result, the switching element only needs that Coupling between the embroidery organ of the embroidery site and the corresponding drive element to solve or engaged bring to the organs of the respective embroidery site switch. The drive elements can continue to operate and thus be common to all embroidery sites.

The coupling member is a one and switchable organ by spring force in the engaging position or by the switching element against the spring force in the non-engaging Position held. All are expedient Coupling elements by spring force in the engaging Position held.

The switching element expediently has a switching rod to actuate the coupling member. This shift rod has advantageously a trough in which the coupling member in the non-engaging position so that the forces which from the coupling member to the shift rod of the Switching element act, the switching element can not move and the coupling member remains safely switched off. By the The coupling elements can snap into the shift rod the deactivated organs, such as the needle, drill and Thread guide, not even due to machine vibrations switch on again automatically.

The switching element is expediently pneumatic actuatable. Alternatively, a hydraulic or a motorized operation possible. The pneumatic actuation the switchgear is preferred because it is very clean, is inexpensive to maintain and easy to control.

The thread guide between two thread deflection members is advantageous arranged and essentially transverse to Thread running direction movable by the length of the thread running line to change between the two deflection elements. This will the thread in a V-line between the thread deflection elements guided. This V-line is depending on the position of the thread guide different flat and can be in one position of the thread guide to be a straight. Threading is in this position of the thread very simple and could also be automatic be accomplished because the thread is none Direction changes.

The thread guide is preferably essentially vertical moveable, because this means that the Needle carriage not the working thread guide of an embroidery site comes into conflict with the thread guide that is switched off neighboring embroidery site.

An embroidery machine according to the invention advantageously has End of a thread guide lever on an eyelet, which as Thread guide is used, the thread guide lever by a Actuator is actuated. This is the thread optimally managed. The eyelet can also be a hanging eyelet. A shaft is advantageously provided, in which the Thread guide lever or thread guide tappet translational is mobile. The shaft is expedient pivoted. This allows the thread guide lever Curve of an operating lever pivoting about an axis consequences. And the thread guide lever can act as a coupling element serve.

In another expedient embodiment, the Thread guide lever articulated. One is advantageous pivotable intermediate lever provided on which the Thread guide lever is articulated. This in turn to the thread guide lever to allow the curve one To follow the operating lever and around the thread guide lever as to be able to use pivotable coupling element.

The thread guide lever itself, where its This allows freedom of movement as a coupling element educated. So an additional part with a game having joint can be avoided.

Are the actuators on a common Actuating shaft arranged, so is preferably at least one independent of the individual embroidery stations actuable switching element provided to the needles and / or switch the thread guide of a needle carriage on and off.

The invention also relates to an embroidery machine, in particular Schifflistickmaschine, in which a thread guide as one the stitch formation organs serves. According to the invention Thread guide in an embroidery machine of this type between two thread deflectors arranged and essentially transverse Movable to the direction of the thread by the length of the Thread running line between the two thread deflection elements change. This enables the thread guide to be in one position a thread guide without changing direction. This allows the Thread can also be threaded by machine.

In such an embroidery machine, the Thread guide essentially vertically movable. Preferably the thread guide pulls the thread down from the direct one Connection line between the two deflection elements in one V line gone. As a result, the thread guide can be a rod and operate all embroidery points at the same time. Even with one continuous bar is threading under the bar through, e.g. with a blower, in the simplest way can be automated because the thread is threaded in a straight line can.

A separate one is advantageous for each embroidery site Thread guide arranged, which is independent of the Thread ladders of the other embroidery points can be switched on or off is. The thread guide advantageously has a thread guide lever and an eyelet on it. The thread guide lever is advantageous by means of an actuator that can be engaged and disengaged actuatable.

The schematic representation of Figure 1 shows a number from embroidery sites S1, S2, S3 ... which, as will be explained later is carried out, individually by an embroidery switching device (Figure 2: 71) can be switched on and off. A drive shaft 11 driven by a motor 10 is used the drive of the presser 13, the needles 15 and the Thread guide 17. For this purpose, cam disks 19, 21, 25 intended. The cam disc 19 acts via the cam lever 27 on the presser 13. The cam disc 21 acts the cam lever 31 on the needle ruler 33. The cam 25 acts on the thread guide ruler via the cam lever 35 37.

The drill drive 39 is also shown schematically. about the lever 41, the drill ruler 42 is pivotable. Because needle 15 and drill 43 arranged at a distance from each other must be before and / or after the drilling operation Tensioning frame (not shown) on which the embroidered Fabric is stretched, moved. The must The presser 13 should be lifted off. To make this possible e.g. a clutch 45 is provided which at a Drilling operation can be operated. Since drill 43 and needle 15 are not the drive shaft is stationary 11 silent when drilling.

To allow the switching off of an embroidery site is both the needle plunger 47 and the drill plunger 49 with a Coupling member 51 and 53 provided. The respective Coupling member 51, 53 expediently has the shape of a Lever with a trough 55 or 57, with which he on Needle ruler 33 or drill ruler 42 can snap into place.

The thread guide 17 of each embroidery site is also individual can be switched on and off. The thread guide 17 is in the illustrated embodiment from a pivotable Lever, which is mounted on the axis 59. The lower part of the thread guide 17 consists of a sleeve 61 in which a thread guide plunger 63 is slidably mounted. The Thread guide plunger 63 has an eyelet 65 for thread 67 and a coupling member 69, which engages in Figure 1 is shown with the thread guide ruler 37.

If an embroidery point is to be switched off, then by a switching device, the coupling members 51, 53, 69 disengaged, i.e. the levers 51, 53 will be raised and the thread guide 17 becomes counterclockwise panned.

Figures 2 and 3 show one of the embroidery sites S1, S2, S3 ... from FIG. 1 with the embroidery point switching device 71 to switch the embroidery point on and off. The embroidery point switch 71 consists essentially of that of the Control unit (not shown) or controllable by hand pneumatic cylinder 73 and the associated Shift rods 75 (only shown in Figure 2) and 77. Die Shift rod 75 controls the coupling members 51 and 53 of Needle 15 and drill 43 and the thread guide 17. Die Shift rod 75 has sliding surfaces 79, 79 'for lifting the Coupling members 51 and 53 and a driver 81 for Swiveling the thread guide 17 on. Furthermore, the Shift rod 75 troughs 82, 82 'into which the coupling members 51, 53 with the lugs 83, 85 in the switched-off position can snap into place. Slide the shift rod 75 forward the lugs 83, 85 of the coupling members 51 and 53 on the sloping sliding surfaces 79, 79 'on the shift rod 75 and are raised so far that they no longer are in engagement with the rulers 33 and 42 respectively. At the The shift rod 75 is advanced by the driver 81 also the thread guide 17 on the nose 87 detected and in Counterclockwise swiveled so far that it is out Engagement with the thread guide ruler 37. A transfer the movement of the rulers 33, 42, 37 on the drill 43, the Needle 15 and the thread guide 17 of this embroidery site is thereby prevented.

The shift rod 75 is with play with the shift rod 77 coupled. As a result, the thread brake 89 and Thread monitor 91 controlled. When the Shift rod 75 is through the driver 76 with a Delay moves the shift rod 77 and the thread brake 89 and the thread monitor 91 switched off. Accordingly when the shift rod is subsequently moved back 75 also pushed the shift rod 77 back with a delay and the thread brake 89 is reconnected to the thread roller 93 and the thread monitor 91 put into operation.

The between the sleeve 61 of the thread guide 17 and the Machine frame arranged spring 95, maintains activated embroidery site engages the thread guide 17 with the thread guide ruler 37. Likewise, on the ram 49 and a spring on the needle plunger 47 (not shown) arranged to the coupling members 53, 51 against the rulers 42 and press 33.

Since needles 15 and thread guides 17 from the same shaft 11 are driven for switching off the needles 15 or the thread guide 17 of all embroidery sites separately Switching devices 94 and 96 are provided. In Figure 3 is to Explanation of the function of these switching devices 94.96 Shift rod 75 has been omitted. The switching device 94 for the needles 15 has 99 lever 97 on a drive shaft on which a ruler 101 is arranged. With the ruler 101 is a switching rod 103 in at each embroidery point Intervention. With the shift rod 103, the needle 15 is in same way as with the shift rod 75 on and can be switched off. The shift rod 103 is with bolts 105 in Elongated holes 107 (Figure 2) attached to the shift rod 75 and translationally independent of the shift rod 75 movable.

The switching device 96 for switching off the thread conductors 17 has a pivotable lever at each embroidery point 109 on a drive shaft 111. On these levers 109 are each driver 113 with troughs 115 for receiving the Lugs 87 of the coupling members 69 of the thread guide 17th arranged. To turn off the thread guide 17, these are by the driver 113 against the force of the spring 95 in Swiveled counterclockwise and out of engagement with the Thread guide ruler 37 brought.

At a distance from the thread guide 17 there are deflection elements 117 and 119 , e.g. Bars or sheets, arranged for the thread 67. The Thread 67 runs over the deflection element 117, through the eyelet 65 of the thread guide 17 and via the deflection element 119 to the needle 15. The thread course has the shape of a V. Depending on the position of the thread guide plunger 63 in the sleeve 61 is the angle between the legs of the V smaller or larger. In the highest position of the thread guide plunger 63 is the The thread runs practically straight.

Another embodiment is shown in FIGS Embroidery site shown, namely in Figure 4 in switched on and in Figure 5 in the off state. The drive of the presser 13, needle 15 and thread guide 17 ' takes place via three shafts 11 ', 11 ", 11' ''. The cam disk 19 on the shaft 11 'acts on the cam lever 27' Presser 13. The cam disc 21 acts on the shaft 11 ″ via the cam lever 31 'on the needle ruler 33. Die Cam 25 on the shaft 11 "'acts on the Cam lever 35 'on the thread guide ruler 37 the individual organs 13, 15, 17 by separate shafts 11 ', 11 ", 11 '' 'are driven, the need of Switching devices for switching the on and off together Thread conductor 17 or the needles 15. For switching on or off the corresponding shaft is driven or shut down. The thread guide 17, for example, by decommissioning the Shaft 11 '' 'switched off together.

However, an embroidery point switching device 71 'is on and off Switching off the respective embroidery location provided. Therefore is a pneumatic cylinder 73, a shift rod 75 'and a shift rod 77 is provided which the parts 73, 75 and 77 from the first exemplary embodiment from FIGS. 2 and 3 correspond. Only that is slightly different Shift rod 75 ', because no shift rod for common Switching the needle 15 is more necessary and the thread guide 17 'is designed differently.

The thread guide 17 'has a thread guide lever 63', which at one end with an eyelet 65 and at the other end with a trough 121 for engaging on the thread guide ruler 37 is provided. This thread guide lever 63 'is articulated mounted on an intermediate lever 123, which at 124 is pivotally attached to the machine frame. The Thread guide lever 63 'remains approximately when it is actuated vertical orientation. The eyelet 65 performs on everyone Rotation of the drive shaft 11 '' 'a down and up movement. The thread 67 becomes like the previous one Embodiment in a V-line between two Deflectors 117 ', 119' pulled down and into one about stretched line subsided again.

The individual thread guide 17 'is through the embroidery point switching device 71 'can be switched on and off. This is what a Driver 81 'on the shift rod 75'. The driver 81 ' has a trough 82 'which is used to switch off the Thread guide 17 'with a pin 125 on the thread guide lever 63' cooperates. If the embroidery site is switched off, like this in Figure 5 is shown, the thread guide lever 63 ' opposite the intermediate lever 123 in a counterclockwise direction Force pivoted by a spring so that the trough 121 does not is more engaged with the thread guide ruler 37. Thereby is the individual thread guide 17 'of the switched off Embroidery site shut down while the thread guide 17 'of continue to work with the embroidery positions switched on.

As FIG. 5 shows, coupling members 51 and 53 of the needle are seated 15 and drill 43 with their embroidery position switched off Noses 83 and 85 in troughs 82, 82 'of shift rod 75'. By means of sliding surfaces 79, 79 'on the shift rod 75' Coupling members 51.53 when pneumatically actuating the Shift rod 75 'raised from the engaging position been. Therefore, the needle ruler 33 and Move the drill ruler 42 in the switched-off embroidery location, without operating the needle 15 or the drill 43.

To switch on the embroidery point, switch rod 75 ' moved back by spring force or pneumatically. The Coupling members 53 and 51 are subsequently by springs (Not visible, since there are recesses in the coupling member 51, 53 Leaf spring) pushed back into the engaging position. The thread guide lever 63 'is also by a spring (not shown) counterclockwise into that with the Thread guide ruler 37 engaging position pushed.

Another embodiment of an embroidery site is in the Figures 6 and 7 shown. This example differs differs from the previous one essentially by the thread guide 17 ". During drive and coupling of presser 13, drill 43 and needle 15 are identical, is about an axis 127 pivotable thread guide lever 63 '' a coupling member 131 pivotally attached, which with a trough 121 ' the thread guide ruler 37 is engaged. The Pivotal movement of the thread guide ruler 37 is about Transfer the coupling member 131 to the thread guide lever 63 ″, whereby the eyelet 65 '' arranged on the thread guide lever for each Rotation of the drive axis 11 '' 'a forward and backward movement accomplished. This will thread 67, which in conventionally in a Z line through the small one Thread guide 133, back to the large thread guide 17 '' and after Is guided to the front of the needle 15 in every machine cycle withdrawn and eased forward. The movement of the Eyelet 65 '' of the thread guide 17 '' is accordingly practical horizontal.

The coupling member 131 is with a sliding surface 79 ″ on the Shift rod 75 '' from the engaging position (Figure 6) liftable. With the embroidery position switched off (Figure 7), the Coupling members 51 and 53 of the needle 15 and the drill 43 also the coupling member 131 of the individual thread guide 17 '' off the corresponding ruler 33,42,37 so that the rulers 33,42,37 can move without the To drive the embroidery site.

The thread guide 17 '' is in the position in which the thread 67 is longest, can be switched off. This makes the thread 67 taut and no thread loops can form, which is with an adjacent working thread guide 17 '' could impose. For the thread guide plunger or -lever 63, 63 'of the exemplary embodiments according to FIGS. 1 to 3 or 4 and 5, this consideration is irrelevant because in the vertically movable thread conductors 17, 17 'none Can impose thread loops.

The essential idea of the invention of the individual, individually pro Embroidery thread switchable thread guide can also be different designed embroidery machines, e.g. with the drive elements below the needle carriage.

In summary, it can be said from FIG. 1 that on an embroidery machine over cams (25) on a Drive shaft (11) and a scanning the curves Cam lever (35) a thread guide ruler (37) is driven. Each embroidery site (S1, S2, S3 ...) has an individual one Thread conductor (17) via a coupling piece (69) on Thread guide lever or tappet (63) engages with the Thread guide ruler (37). By a not shown Switching element (Figure 2: 75) at each embroidery point (S1, S2, S3 ..) can individual embroidery points (S1, S2, S3 ...) including the individual thread guide (17) from the drive elements (11,19,27; 11,21,31,33; 11,25,35,37) solved and thereby be shut down.
