Description
Technical field
The present invention relates to a kind of device, this device is used to drive function element on the track that is arranged on the longitudinal axis that is parallel to straight-bar machines, that can vertically move, especially thread-carrier, this device has one and can mesh with function element and out-of-gear engaging pin (Mitnahmefinger).
Background technology
Generally exceeding on the optional position of planting pin spacing of straight-bar machines and driving or the function element of stopping, for example thread-carrier or shearing equipment on the straight-bar machines by being arranged in geared assembly on the cam carrier.Geared assembly has one and can mesh and out-of-gear engaging pin with function element for this reason.In addition, by in the geared assembly of prior art, engaging pin can also trigger the switching function of function element at some, as the gyration of the transverse arm of embossing thread-carrier.Wherein come the operable engagement pin with electromagnetic mode usually.
Open in addition, to the insurance institution of a form of springs of geared assembly outfit, engaging pin can overcome its elastic force and break away from engagement with function element in short time in its position of engagement.For this reason can be on function element such as rising ramp is set.Behind the process rising ramp, engaging pin meshes with function element once more.This measure is used to prevent the collision between the function element, and such collision can cause the destruction or the damage of engaging pin.Such as in DE 39 22 513 C2, just a kind of such geared assembly being illustrated.
If engaging pin also should trigger the switching function on the function element except driving function element, and the triggering of these switching functions must be staggered in time with the drive of function element, that is to say before driving function element or after the closing function element, on by the geared assembly of prior art, must correspondingly design function element longer so, so that the engaging pin of geared assembly is such as can at first trigger a switching function before it drives this function element.Needed time warping between switching function and engagement capability what, the switch surface on the function element correspondingly must be arranged far according to from the mating surface of function element.But the function element of elongate structure has such shortcoming, promptly can only arrange a limited number of this function element along the predefined length of track.
In DE4407708C2 a kind of straight-bar machines is illustrated, its geared assembly has two engaging pins respectively.Also can drive the short function element of structure thus.But be provided with one of function element extra switching function is not triggered with second engaging pin.Or rather, should abandon a kind of controlled embossing thread-carrier by additional engaging pin.In addition, this geared assembly by prior art is very bothersome technically.
Summary of the invention
Task of the present invention provides a kind of geared assembly, utilize the function element that this device also can drive and switching construction is very short, and this device is simple in structure technically.
This task utilizes a kind of device to be resolved, this device is used to drive the function element that can vertically move on the track that is arranged on the longitudinal axis that is parallel to straight-bar machines, especially thread-carrier, this device has one and can mesh and out-of-gear engaging pin with function element, be characterised in that by this device of the present invention, it has at least one switch projection in addition, this switch projection is arranged in the front or the back of engaging pin on the traffic direction of function element, and can mesh with the switch surface on the function element and break away from engagement, be used to trigger the switching function of function element.
The necessary switching function of function element triggers by described at least one switch projection, rather than is triggering by an engaging pin on the geared assembly of prior art by resembling.
Preferred this device can be arranged in to fixed-site on the cam carrier of straight-bar machines, and can be driven by this cam carrier thus.If engaging pin is arranged in the top of a Trianguli centre of cam carrier in the mode that can move up and down, that just can carry out best location with respect to the expectation place to use of function element with geared assembly and especially engaging pin and described at least one switch projection.
If described at least one switch projection and engaging pin are arranged in the plane that the traffic direction transverse to function element staggers each other, that just produces other advantage.Engaging pin and described at least one switch projection are jointly moved up and down under the situation that does not hinder two element functions mutually.The switch projection then slips over and engaging pin slips over from the switch surface of function element from the field of conjugate action.Two elements only act on the surface into its setting, and these surfaces are arranged in the different planes equally.
If the meshing relation and the switch relation of symmetry are provided on two traffic directions of cam carrier, and/or want on function element, to trigger more than one switching function, two switch projectioies can be set so, these two switch projectioies preferably with between the engaging pin have identical spacing on the traffic direction of function element, in the front of engaging pin, another switch projection then is arranged in the back of engaging pin in this one of them switch projection arrangements.
Can be arranged in the plane that the traffic direction transverse to function element staggers each other in this this two switch projectioies.This can further shorten the structure of function element, because the switch projection only can mesh with the switch surface that is in its plane of function element.These two switch projectioies slip over by the switch surface of another switch projection and by the mating surface of function element.In addition, the switch projection arrangements also can be carried out co-operate to two switch projectioies in different planes.
Engaging pin can mesh and break away from engagement in known manner with electromagnetic mode and function element.Also described at least one switch projection can be meshed and breaks away from engagement with the switch surface of engaging pin and function element at this.This means, only need an electromagnetic actuator device to be used for engaging pin and described at least one switch projection.
But described at least one switch projection also can be independent of a switch surface of engaging pin and function element and mesh and break away from engagement.Although this solution is more bothersome technically, an independent drive unit is set such as an electromagnet because be necessary for the switch projection, but engaging pin and switch projection separately controlled this scheme has but realized the time sequencing between engagement process and the switching process under the cam carrier direction keeps identical situation reverse.In contrast, when engaging pin and described at least one switch projection are driven jointly, then be the time sequencing that the relative position on geared assembly arranges to determine switching process and engagement process by engaging pin and switch projection.
And can have an insurance institution by geared assembly of the present invention, thereby at least engaging pin can with the position of engagement of function element in especially overcome a spring by the rising ramp on the function element elastic force break away from engagement with function element in short time.Avoid when function element that is driven and the collision of other function element, damaging geared assembly and/or function element thus.
For described at least one switch projection, an independent spring element also can be set, the switch projection can be independent of the elastic force that engaging pin overcomes this spring and break away from engagement with function element in short time in its position of engagement.When the switch projection contacted with a rising ramp, this just caused mentioning momently the switch projection.At this advantageously, the elastic force of this spring element is less than the elastic force of the spring element that is used for engaging pin.Then when engaging pin rose to a rising ramp, not only engaging pin but also described at least one switch projection were raised, and when only described at least one switch projection rises to a rising ramp, had only this switch projection to be raised.
Description of drawings
Describe preferred embodiment below with reference to the accompanying drawings in detail by geared assembly of the present invention.
Accompanying drawing illustrates:
Fig. 1 shows the front view of first kind of geared assembly;
Fig. 2 a, 2b show the side view of geared assembly shown in Figure 1, show itself and the engagement of function element respectively and break away from engagement;
Fig. 3 a, 3b, 3c show the front view of geared assembly shown in Figure 1 and the front view of two kinds of flexible programs thereof.
The specific embodiment
Fig. 1 illustrates a kind of geared assembly 1, is arranged in to its fixed-site one on the cam carrier 2 of the straight-bar machines that others are not shown specifically.This device 1 has a guide 10 and one disposed thereon 's bridge shape frame 11.This guide 10 can move up and down along arrow A and T direction in cam carrier 2 with electromagnetic mode, and can mesh (direction of arrow T) with a function element that schematically illustrates 4 thus and break away from engagement (direction of arrow A), function element 4 then can be parallel to here that the track of the longitudinal axis of unshowned straight-bar machines vertically moves along direction of arrow X along one.An engaging pin 13 and two switch projectioies 12,14 on a side of track 3, have been arranged at bridge shape frame 11.Engaging pin 13 just in time is in the Y place, center of geared assembly 1, and this center Y also is equivalent to the center of a Triangulum that schematically illustrates 5 of straight-bar machines.Switch projection 12 and 14 is arranged in the stub area of bridge shape frame 11 symmetrically with respect to engaging pin 13.Two switch projectioies 12,14 are furnished with switch surface 12 ', 12 " or 14 ', 14 ".Engaging pin 13 also has two mating surfaces 13 ', 13 ".Mating surface 13 ', 13 not only " but also switch surface 12 ', 12 " and 14 ', 14 " be arranged in the plane interlaced with each other transverse to the moving direction X of device 1. Element 13,12 and 14 is engaged on respectively on the different switch surfaces or mating surface of function element 4, and can hamper remaining element 12,13,14 at this.Certainly this also causes such situation, and promptly the corresponding switch surface of function element 4 and mating surface are arranged in the plane of staggering each other transverse to moving direction X equally.Switch surface 12 ' is to spacing VL and the switch surface 14 of center Y " determined a time interval to the spacing VR of center Y, the engagement action of being undertaken by engaging pin 13 is led in the switch motion of switch projection 12,14 with this time interval.Switch surface 12 " and 14 ' divide the spacing NR be clipped to center Y and NL determined in the same way engagement action with by the time lag between the switch motion of switch projection 12,14 triggerings.If cam carrier 2 and thus Triangulum 5 also move along direction of arrow L, switch surface 12 ' just causes the switch motion that is ahead of Triangulum 5 on function element 4 so, mating surface 13 ' causes engagement action on function element 4, and switch surface 14 ' causes on function element 4 and lags behind Trianguli switch motion.If cam carrier 2 moves along R in the other direction, so surface 14 ", 13 " and 12 " then priority is to function element 4 generation effects.
Spacing VL, VR, NL, NR needn't immobilize.They also can change when switch projection 12,14 is movably arranged.In addition, in the illustrated embodiment, engaging pin 13 is identical with 14 length with switch projection 12.But equally also can consider the different schemes of the length of element 12,13,14 here.
Be among the engagement with function element 4 if install 1, install 1 locking regularly in this position so.Or rather, it can overcome the elastic force upwards extruding in short time of spring 16, that is to say, breaks away from engagement with function element 4.Spring 16 is bearing on the surface 22 of cam carrier 2, and abuts against the upper side of bridge shape frame 11.Under unpressed state, spring 16 makes the interface 15 of guide 10 touch a surface 21 in the cam carrier 2, and bridge shape frame 11 is in its darkest position thus.
Fig. 2 illustrates a side of device 1, that is to say along according to the direction of motion X of Fig. 1, and wherein Fig. 2 a illustrates the state that device 1 and function element 4 mesh, and Fig. 2 b then illustrates itself and function element 4 out-of-gear states.Fig. 2 shows how switch projection 12,14 is arranged in the different planes with engaging pin 13, and how in these planes with function element 4 on corresponding projection carry out acting in conjunction.The plane of switch projection 12,14 and engaging pin 13 also can exchange.
Figure 3 illustrates the different arrangement of switch projection 12,14 on bridge shape frame 11.The flexible program of Fig. 1 is shown in Fig. 3 a once more.Switch projection 12,14 is connected with bridge shape frame 11 rigidly.If install 1 from right past moving left, switch projection 12 can rise on a rising ramp 8 that is arranged in its plane so, engaging pin 13 arranges that at one the rising ramp 8 ' in its plane rises, and perhaps switch projection 14 is at a rising ramp 8 that is arranged in its plane " go up and rise.In case the rising ramp 8,8 ', 8 under one of them in the switch projection 12,14 or engaging pin 13 and its " contact; bridge shape frame 11 just overcomes the elastic force of spring 16 according to rising ramp 8,8 ', 8 so " height promote in the direction of arrow A, wherein element 12,13,14 is being followed the action of bridge shape frame 11.
In the device 1 ' shown in Fig. 3 b, engaging pin 13 is connected with bridge shape frame 11 rigidly, switch projection 12 " ' with 14 " ' then can vertically be bearing in movably in the bridge shape frame 11, and load by compression spring 6, the elastic force of compression spring 6 is less than the elastic force of spring 16.Spring 6 is with switch projection 12 " ' and 14 " ' remain in its nethermost position, and be supported in cam carrier 2 opposite with shown flexible program.If install 1 ' from right past moving left, and switch projection 12 " in ' or 14 " ' one of them be in its plane in rising ramp 8,8 " contact, have only current switch projection to overcome the elastic force of spring 6 so according to rising ramp 8,8 " height promote in the direction of arrow A.On the contrary, 13 of bridge shape frame 11 and engaging pins do not promote.If engaging pin 13 contacts with rising ramp 8 ' in contrast, bridge shape frame 11 and two switch projectioies 12 so thus " ' and 14 " ' all raise up.
According to the device 1 shown in Fig. 3 c " in, two switch projectioies 12 " " with 14 " " can vertically be bearing in movably in the bridge shape frame 11, and can mesh and break away from engagement with electromagnetic mode and function element 4.Engaging pin 13 is fixedly placed on the bridge shape frame 11.Switch projection 12 " " and 14 " " at direction of arrow A " and on not only can move by electromagnet, and can when rising, move to rising ramp 8 or 8 " on.This also is a kind of safety measure here, is used to avoid damage with other element collision the time geared assembly and/or function element.Electromagnet is at arrow T " direction on to two switch projectioies 12 " " and 14 " " active force less than the elastic force of spring 16, thereby when promoting one of them switch projection, immediately whole bridge shape frame 11 is not together mentioned.If engaging pin 13 contacts with rising ramp 8 ' in contrast, so whole bridge shape frame 11 has just been carried.In this regard, device 1 " role is quite analogous to the device 1 ' shown in Fig. 3 b.But it also has an extra advantage, i.e. two switch projectioies 12 " ", 14 " " can be separated from each other and activate by engaging pin 13, under cam carrier keeps the situation of equidirectional, also can realize the engagement action and the switch motion reverse in time of function element thus.Can before or after driving function element, carry out function element 4 by switch projection 12 by engaging pin 13 " ", 14 " " two or only switch motion triggering.
