Description
The present invention relates to a kind of for opening roller opening tag weaving loom, that there is matrix, described matrix is removably connected with card clothing frame (Garniturtr ger) by rotation latching member, and wherein card clothing frame is used for while being connected with matrix turning to the position of engagement and further turning to the locked position of coupler of terminal from this position of engagement again from unlocked position with respect to the matrix moving axis that rotates.
Known a kind of opening roller for opening tag weaving loom from US4296527A, described opening roller has the rotation latching member that is designed to spiral closure.Matrix has external screw thread and card clothing frame has internal thread herein.The problem is here that, if correctly matrix is not tightened onto to card clothing frame until reach retainer by enough thrusts in advance, card clothing frame may depart from from matrix in the time of operation.The danger existing is in addition, the card clothing frame correctly screwing with matrix after the operation long period because wearing and tearing and/or vibration depart from from matrix.
Therefore, task of the present invention is to provide the opening roller with safe rotation latching member, thereby avoids card clothing frame to depart from from matrix in the time of operation.
This task realizes by having the opening roller of feature described in independent claims 1.
According to the present invention, there is matrix and card clothing frame for the opening roller of opening tag weaving loom.Matrix and card clothing frame are removably connected to each other by means of rotation latching member.Rotation latching member is preferably quick lock part, ensures fast and on matrix, mount and dismount easily card clothing frame by it.In order to connect matrix, card clothing frame can turn to the position of engagement and further turn to the locked position of coupler of terminal from this position of engagement again from unlocked position towards matrix or with respect to the matrix moving axis that rotates.
Card clothing frame and matrix come unlocked position is separated from one another, thus make card clothing frame can with Matrix separation.
In contrast, two members are coupled in the position of engagement at opening roller on axially, thereby make the card clothing frame can be again because of pure axially-movable and Matrix separation.But two members are still insecure being connected to each other of the position of engagement in the tangential direction of opening roller, both can be reversed toward each other in turning cylinder.Card clothing frame and matrix, in the preferably design as follows of coupling of the position of engagement, make the first rear partition shapes of card mounting machine frame engage ordinatedly the second rear subregion into matrix, thereby they are connected to each other to form fit on the axial direction of opening roller.
Only, at locked position of coupler place, the coupling between card clothing frame and matrix is different from the position of engagement, is not only positioned on axial direction, but also is positioned in the tangential direction of opening roller.Card clothing frame is firmly locked with respect to matrix at locked position of coupler, thereby card clothing frame can not be departed from from matrix in the time of operation.
Rotation latching member has at least one locking member.This element can stop card clothing frame to move to unlocked position with respect to matrix from the position of engagement in the time of operation.This is particularly advantageous in following situation, does not correctly turn to locked position of coupler when card clothing frame is connected with matrix in advance.What it is contemplated that equally in addition is, its role is to when for example rotating latching member Bu Jian –, card clothing frame is remained on when closing lock position – and being no longer positioned at this position because of wearing and tearing or the reason of damage aspect with respect to matrix, and the card clothing frame correctly being locked moves to the position of engagement from locked position of coupler.Therefore can advantageously avoid by locking member, card clothing frame departs from from matrix completely in the time of operation.
Advantageously, preferably substantially move at the axial direction of opening roller in latched position with by the locking member between position.Locking member stops card clothing frame to turn to unlocked position from the position of engagement in latched position.Locking member can make card clothing frame turn to the position of engagement to install and make card clothing frame turn to unlocked position from the position of engagement so that dismounting from unlocked position by position.Therefore, advantageously ensure on matrix fast and installation and removal card clothing frame easily, while ensureing operation, card clothing frame remains on the position of engagement simultaneously.
Locking member is advantageously arranged on matrix.Can reduce thus the maintenance cost of opening roller, because wear and tear more severely with matrix phase than card clothing frame.Even if therefore often change card clothing frame but locking member remains unchanged.
Also advantageously, locking member designs as follows, when latched position moves to by position locking member on the axial direction of opening roller at least in part the side at matrix move upward.Can be reduced at thus installation and removal card clothing frame on matrix.Therefore first card clothing frame must be placed on matrix and then it be pressed to matrix, wherein locking member moves to and passes through position from latched position on opening roller is axial.The motion of locking member is preferably yaw motion or shift movement.
Problem is, must be manually by locking member from being moved back into latched position by position.If therefore operating personnel forget in advance locking member is moved back into latched position in this case, the problem likely occurring is that card clothing frame does not lock with respect to matrix.Given this reason advantageously, designs locking member as follows, makes after deflecting into by position, and when particularly installing on matrix and/or dismantling card clothing frame, locking member automatically returns to latched position again.
Again automatically return to latched position self-locking locking member can by ground simple in structure and low price realize, method be locking member is designed to flexible.At this moment locking member can be designed to elastomeric element completely, but also can only have region or the parts of single Flexible Design.The locking member of Flexible Design is to design as follows, and make it is elastic unloading (federentlastet) for elasticity loading (federbeaufschlagt) and/or in latched position in the time deflecting into by position in latched position direction.Consequently, user must overcome elastic force threshold value when installation or removal card clothing frame on matrix, and described threshold value is determined by the spring force of locking member.For locking member is moved to by position from latched position, user must apply the assembly force that exceedes elastic force threshold value.Meanwhile, there is so large elastic force threshold value, make the power that turns that locking member is produced in service be no more than this elastic force threshold value.
If locking member is designed to spring or elastic locking element, there is following danger,, in the time of installation or removal card clothing frame, locking member or its parts produce plastic deformation, and reason is that the assembly force that user applies has exceeded plastic deformation threshold value.Therefore advantageously, the locking member of Flexible Design has at least one overstress stops, and before locking member generation plastic deformation, particularly in the time deflecting into by position, it is fixing in overstress stops.
In a favourable improvement project of the present invention, locking member is designed to lock spring legs.It preferably has pedestal, free end and is arranged in the bending area between the two.At least a portion in bending area and/or free end are designed to can be around pedestal (particularly on the axial direction at opening roller) in latched position with by pivotable or deflection between position.Like this can be simple in structure and low price realize locking member.
Advantageously, locking spring legs and turning cylinder maintain a certain distance and/or substantially in the tangential direction at opening roller, extend at axial direction.Locking spring legs can be designed to obtain to long enough thus, thereby make to mate with elastic force threshold value, result is to guarantee to mount and dismount simply card clothing frame on card clothing ring.Therefore mode is mated with elastic force threshold value as follows simultaneously, makes the power in the time of operation, the locking member of card clothing frame being produced be no more than elastic force threshold value, thereby avoids card clothing frame to move to unlocked position from the position of engagement.
Also advantageously, locking spring legs (especially on bending area and/or free-ended region) has domatic, and this is domatic tilts with angle [alpha] with respect to pedestal, particularly tilts in matrix direction.Therefore particularly the Connection Element of card clothing frame slides into unlocked position along domatic from the position of engagement when mobile, thereby makes card clothing frame to move to unlocked position with respect to matrix.
Can improve in addition the movement from the position of engagement to unlocked position with respect to matrix of card clothing frame, approach is that locking spring legs has outlet area (Ausf ü hrbereich) in its free-ended region, particularly has curvature (Rundung).Can avoid thus the free end locking in the locked spring legs of dismounting card clothing frame hour hands cloth frame, particularly by the Connection Element locking of card clothing frame.
In order to ensure simply card clothing frame being disassembled from matrix, advantageously, outlet area tilts with angle beta with respect to pedestal, particularly tilts in matrix direction, and angle [alpha] is preferably less than angle beta simultaneously.
Advantageously, rotation latching member has at least one and is arranged on a member in these two members, be arranged in matrix or card clothing frame, be in particular the hook-shaped Connection Element with stop rib, also have be arranged on another member, be particularly designed to blocking element case spring supporting leg, that there is stop shoulder, and/or stop shoulder is at locked position of coupler engagement stop rib, thus make these two members axial direction relative to one another elasticity load and card clothing frame is firmly locked in locked position of coupler by blocking element.
Also advantageously, the free end of locking spring legs is adjacent with the pedestal of case spring supporting leg in the tangential direction of opening roller.Can ensure thus card clothing frame, particularly the Connection Element of card clothing frame is encountered the free end of locking member, and condition is that card clothing frame is not correctly locked in locked position of coupler in advance.
Rotation latching member can be simple in structure together with at least one locking member and low price realize, condition is that at least one locking spring legs and at least one case spring supporting leg are done as a wholely to form, and is particularly designed to the leaf spring of single type.
In the German patent application that rotation latching member is preferably 102012100526.5 according to application number, one or more features of disclosed quick lock part build.
Therefore card clothing frame is arranged for the opening roller of the opening tag weaving loom of the moving axis rotation that can rotate.It has quick lock part, card clothing frame removably can be fixed on the matrix of opening roller by this quick lock part.Quick lock part is designed to rotate latching member, thereby card clothing frame can removably be coupled together with matrix by means of the rotation around turning cylinder, and wherein rotation is to carry out with respect to the matrix arranging for this reason.Ensure thus fast and simply card clothing frame to be arranged on matrix or from matrix and to be disassembled.Guarantee card clothing frame to be fixed on matrix firmly by rotation latching member, because particularly can not cause card clothing frame to depart from from matrix to connecting the power producing in the axial direction simultaneously.
Fixing on matrix of card clothing frame will be more firm, and condition is that rotation latching member is designed as follows, even if must be used for, card clothing frame will be locked to rotation on matrix and the direction of rotation of opening roller.The main cause of doing is like this, is applied to main power and direction of rotation in the connection between card clothing frame and matrix in the time starting opening roller and unclamp fiber roll.Can avoid like this causing card clothing frame unexpectedly to depart from from matrix because opening roller rotates in rotation direction.
Advantageously, card clothing frame has at least one radially spaced Connection Element.This Connection Element so designs, and makes it to keep mating with the elastomeric element of matrix.Can form thus in the axial direction and being connected of elastomeric element form fit.Connection Element is preferably hook-shaped.Selectively or addedly also it can be designed to rear subregion, rib and/or the groove in card clothing frame.Thus, advantageously very simple and not highland manufacture of cost of rotation latching member.In addition also can guarantee the connection of form fit very firm and stable between card clothing frame and matrix, thereby avoid departing from from matrix because the impact of axial force causes card clothing frame.
Advantageously, Connection Element has the first opening and/or the second opening for inserting elastomeric element, and the first opening direction is tangential direction, and the second opening is preferably radially inside.The rotation latching member that formed is like this saved space very much.So also can be advantageously that elastomeric element is radially inside, and Connection Element correspondingly is radially outward arranged on card clothing frame and/or matrix, can make like this structure of elastomeric element simpler.
Also advantageously, Connection Element has spring stop surface for insert and tighten elastomeric element in rotation process, thereby ensures that card clothing frame is correctly locked on matrix.In addition this point also advantageously, leave from the matrix arranging for this reason by spring stop surface instruction, or instruction is towards card clothing frame because card clothing frame by spring force pressure to matrix, this spring force is produced by the elastomeric element that presses to spring stop surface.
Also advantageously, card clothing frame has at least one first stop surface, and it can match with the first stop surface of matrix, makes in tangential direction, to form the connection of form fit between card clothing frame and matrix.When the card clothing frame for being connected with matrix is with respect to matrix, while particularly rotation towards rotation direction, these two first stop surfaces are adjacent to each other.Between card clothing frame and matrix, particularly, towards the rotation direction of opening roller, form the connection of stable especially form fit like this, this connection can be born very large power.In the time that opening roller rotates, avoid thus the connection between Connection Element and elastomeric element surprisingly to unclamp.In a preferred implementing form, the first stop surface is arranged in card clothing frame, makes it point to tangential direction.Therefore the first stop surface can bear very large power, and card clothing frame is without sliding with respect to matrix.
Selectable or supplementary advantage is, card clothing frame has at least one second stop surface, and it is corresponding with the second stop surface of matrix, makes to form in the axial direction the connection of form fit between card clothing frame and matrix.When the card clothing frame for being connected with matrix is with respect to matrix, while particularly rotation with direction of rotation, two the second stop surfaces are not adjacent to mutually, but leave gap to each other.Therefore,, in the time that card clothing frame removes from matrix mistakenly by axially-movable, the second stop surface is as the overload protection of elastomeric element.In a preferred implementing form, the first stop surface is arranged in card clothing frame, makes it point to axial direction.Thus, the second stop surface can bear very large power, and card clothing frame is without sliding with respect to matrix.
The first stop surface can be especially simple and cost do not form on highland, condition is when the first stop surface, particularly as platform (Absatz), while being arranged on Connection Element.In addition, can make like this to rotate special the saving spatially of latching member and construct, because can form overlay region between the second stop surface simultaneously.
Advantageously, platform preferably in the region of the first side of Connection Element, form and/or preferably the first side point to rotation direction, because in the time that card clothing frame is locked in matrix and rotate with the direction of rotation of opening roller, being connected of the form fit of the first side and the Connection Element contact of matrix therefore formation and direction of rotation.
For card clothing frame is disassembled from matrix, card clothing frame direction with respect to card clothing frame in opening roller rotation direction must be reversed.For fear of unintentionally once card clothing frame being departed from and provides anti-feedback letter breath – card clothing frame sound and/or sense of touch to be correctly fixed on base body – advantageously in the time that card clothing frame is installed to user from matrix, card clothing frame has stop rib, and this stop rib can mate with the stop shoulder of the elastomeric element of matrix.
When stop rib being arranged in interval in tangential direction on the Connection Element of the first side, particularly, in the second lateral side regions of Connection Element, compact structure is achieved.In addition two only just contacts in the time that stop shoulder engages into stop rib of stop surface of coupling mutually.Platform is preferably placed on two relative sides of Connection Element with stop rib.
Advantageously, card clothing frame has elastomeric element, and this elastomeric element can match with the Connection Element being arranged on matrix.
Also advantageously, card clothing frame have multiple in tangential direction mutual spaced Connection Element.Therefore single Connection Element can design more a little bit smallerly, because the power producing has been assigned on multiple Connection Elements.
According to a favourable improvement project of the present invention, card clothing frame (particularly in its end region) has at least one radial depressions, the radial protrusion (the particularly radial protrusion in its grooved area) of this depression and matrix can be intermeshing, makes to have formed at least one direction in two tangential directions the connection of form fit.Thereby serve as critical component (Schl ü sselelement) with coding (codierte) angle position and/or depression that shape was formed in tangential direction, ensure thus, only have described card clothing frame can be arranged on the matrix being formed by coding projection, described card clothing frame has the respective recesses matching with projection.Evitable like this, can add large – and be fixed on matrix because of the loosening dangerous risk that causes the accident that improves therefore its quality of product – imitative processed of card clothing frame can not be guaranteed.In addition for by card clothing frame and card clothing ring two-piece type for the card clothing frame that forms, the advantage that depression has is, only has when card clothing ring correctly when directed towards matrix, it and matrix could be coupled together.Moreover the connection of the form fit between matrix and card clothing ring forming in this way ensures to drive safely card clothing ring in rotation direction.Therefore avoided card clothing ring to skid.
If card clothing frame be single type form or card clothing frame be torsionally connected with card clothing ring, advantageously, being recessed on certain angular range in tangential direction extended, and this angular range conforms to respect to the rotational angle of matrix with card clothing frame substantially.Therefore can ensure, card clothing frame can screw in matrix, and condition is that matrix has at least one projection.Therefore, mutually the depression of coupling and projection only in a direction in two tangential directions (particularly with in the direction of direction of rotation) form being connected of form fit of card clothing frame and matrix.
Also advantageously, card clothing frame two-piece type ground forms, and wherein card clothing frame has card clothing frame and the card clothing ring being connected with this card clothing frame.Can reduce like this spare parts cost, no longer need to have replaced whole card clothing frame because substantially only need to replace card clothing ring.
If arranged at least one Connection Element on card clothing frame, card clothing ring can advantageously axially be pressed between card clothing frame and matrix.
Advantageously, there is matrix and card clothing frame for the opening roller of opening tag weaving loom.Preferably, can torsionally opening roller be fixed on the driving shaft of opening tag weaving loom by matrix.Card clothing frame preferably has the card clothing for unclamping fiber roll.Matrix and card clothing frame can be rotated and removably be connected to each other by quick lock part around total turning cylinder.Quick lock part is designed to rotate latching member, and card clothing frame can removably be coupled together with matrix by the rotation of the moving axis that rotates with respect to matrix.The connection of guaranteeing thus between matrix and card clothing frame (particularly in the axial direction) very firmly and safety, thereby avoid card clothing frame to depart from from matrix.In addition, rotation latching member makes it possible to mount and dismount simply and rapidly card clothing frame, so greatly shortened the maintenance time of the maintenance time for changing wear-out part, particularly card clothing frame.
In an improvement project of the present invention, as previously mentioned, the feature wherein mentioned can also can exist by any combination by individualism the structure of card clothing frame.
Advantageously, card clothing frame is connected ordinatedly with base shape in the axial direction.Therefore the connection between card clothing frame and matrix can be born king-sized power in the axial direction, thereby ensures that card clothing frame is fixed in matrix safely.In addition selectable or supplementary advantage is, card clothing frame forms the connection of being connected of form fit or power cooperation at tangential direction and matrix.This situation can be avoided especially when card clothing frame is in the time being connected ordinatedly with base shape with the direction of rotation direction of opening roller, and this card clothing frame is unexpected to depart from from matrix.The connection of this form fit is suitably in especially opening roller when rotation and bears very large power while unclamping fiber roll by card clothing, and this masterpiece is for the connection between card clothing frame and matrix, particularly with direction of rotation act on.This power working with the direction of direction of rotation, it also can produce in the time that opening roller starts.In contrast, in the time that opening roller moves, in rotation direction, effect has very little power.Therefore advantageously, card clothing frame, particularly in the rotation direction of opening roller, power is connected with matrix ordinatedly, because so in the time that being connected enough between card clothing frame and matrix is strong, has also ensured the easy installation and removal on matrix of card clothing frame simultaneously.Active force in rotation direction only just occurs substantially in the time of braking opening roller.The connection that card clothing frame and the matrix power in opening roller rotation direction coordinates and/or the connection of form fit will form as follows, make it in the time there is described brake force, can not unclamp.
Also advantageously, matrix and/or card clothing frame have the Connection Element that at least one and turning cylinder radially keep certain distance.Therefore, just can be by Connection Element and parts correspondingly (particularly elastomeric element) engagement by simple rotational motion.For this reason, be favourable when Connection Element is preferably when hook-shaped.Alternatively or extraly, Connection Element also can be designed to rear subregion, depression, projection, groove and/or the rib in matrix and/or card clothing frame.In addition Connection Element also can have the first and second openings, and parts (particularly elastomeric element) correspondingly and/or similarly Connection Element are engaged in described opening at least in part.In addition the Connection Element that designs grooving and/or seam can extend on the four corner of matrix and/or card clothing frame.For card clothing frame axially being inserted to matrix, the Connection Element of design grooving and/or rib has at least one recess, wherein can insert parts (particularly elastomeric element) and/or other Connection Element correspondingly.Therefore advantageously, the Connection Element in matrix and/or card clothing frame can simple especially and not highland manufacture of cost.
For card clothing frame and matrix are coupled together as follows in the rotation direction of opening roller, card clothing frame can be arranged on matrix and also like a cork can be disassembled from matrix very like a cork, advantageously, matrix and/or card clothing frame have elastomeric element, particularly leaf spring.Obviously elastomeric element also can be designed to any other spring well known in the prior art.Elastomeric element is arranged in such a way in matrix and/or card clothing frame, and it is compressed matrix and card clothing frame (particularly in the time engaging into Connection Element) mutually in the axial direction.The connection so just coordinating in tangential direction formation power between matrix and card clothing frame.The thrust of elastomeric element is so big, the connection on one side in the time of braking opening roller can not be unclamped, and the connection on its another side just can be unclamped simultaneously by ordinary people's arm strength.So both ensured card clothing frame to be installed fast and simply and card clothing frame is disassembled from matrix, also ensured that card clothing frame can not depart from from matrix simultaneously.In addition, guarantee in shredding region by mutual compression, particularly in card clothing region, make formation gapless connection substantially between card clothing frame and matrix.Therefore do not have fiber retention wherein, these fibers are because constantly stacking and may cause spinning inhomogeneous and/or polluting in the time of shredding afterwards.
Advantageously, matrix and card clothing frame have at least one first stop surface and/or the second stop surface separately.The first stop surface is arranged in such a way in matrix or card clothing frame, and when card clothing frame is rotated with respect to matrix, thereby while particularly coupling together with matrix towards contrary rotation direction rotation, matrix and card clothing frame abut against each other.Advantageously be formed on being connected of form fit between card clothing frame and matrix in tangential direction thus, so rotate latching member, particularly with the direction of the direction of rotation of opening roller on, can bear very large power, described power particularly can act on described rotation latching member in the time that opening roller starts and in the time that fiber roll is unclamped.Advantageously determine the predetermined turned position of card clothing frame with respect to matrix by the first stop surface abutting against each other in addition, wherein the Connection Element of card clothing frame and/or elastomeric element are engaged in the Connection Element and/or elastomeric element of matrix ideally.
The second stop surface is arranged in such a way in matrix and card clothing frame, makes it can form in the axial direction the connection of form fit.For this reason, the preferred axial orientation of the second stop surface and toward each other.In the time that card clothing frame and matrix interconnect by rotational motion, the second stop surface does not abut against each other, but leaves each other certain gap.For this reason, the second stop surface is as the overload protection of elastomeric element.Described overload only just occurs in following situation, when user does not attempt the rotation by matrix, but unclamps card clothing frame by the axially-movable of straight line mistakenly.Therefore, cause distortion thereby elastomeric element may exceed its flexible scope, result makes card clothing frame no longer be close to matrix.But before described overload appears in elastomeric element, the second stop surface mutually collides and prevents that by the connection of the form fit that forms thus card clothing frame from further departing from matrix in the axial direction.
In order to reduce production costs advantageously, on elastomeric element, particularly in its free end region, the first stop surface is set, and/or (particularly in its first lateral side regions) arranges the first and/or second stop surface on Connection Element.Can be simply, low cost and/or save and produce spatially the second stop surface, condition is that the second stop surface forms in Connection Element with the form of platform.In addition can be so also that the second stop surface arranges overlay region, simultaneously.Connection Element advantageously has the first side and the second side, wherein the rotation direction that is oriented to opening roller of the direction of rotation of the first side and opening roller and the second side.For in tangential direction (particularly and in the direction of direction of rotation) guarantee to form being firmly connected of form fit between these two Connection Elements, platform is preferably structured in first lateral side regions of Connection Element of card clothing frame.
Also advantageously, elastomeric element has at least one stop shoulder is set with free-ended resilient legs and in this free-ended region, and it engages into the stop rib of matrix and/or card clothing frame.In the time of the engagement of stop shoulder, installation personnel can advantageously obtain the feedback information of sound and sense of touch, he just learns that when card clothing frame can be positioned at respect to the correct angle position of matrix, ensures that in this position card clothing frame is firmly tightly locked in matrix exactly like this.In addition, intermeshing stop shoulder and stop rib form the connection of form fit and/or the connection that power coordinates in tangential direction, can prevent from thus rotating latching member surprisingly loosening, and the accident particularly occurring in the time that braking shredding is moving is loosening.
In a preferred implementing form, stop rib be formed in tangential direction with the first spaced Connection Element in side on, be particularly formed in the second lateral side regions of the Connection Element corresponding with elastomeric element.For this reason, when the first stop surface is adjacent to each other in the time that tangential direction forms the connection of form fit, the stop shoulder of elastomeric element be engaged to stop rib after.
Advantageously, matrix and/or card clothing frame have at least two (particularly multiple) Connection Elements, and these Connection Elements come in tangential direction each interval, particularly equidistantly spaced apart.Each such Connection Element has respectively an elastomeric element and/or resilient legs, and they are mated mutually.The Connection Element that formed like this can be saved space, because the active force in tangential direction and is axially assigned on all Connection Elements fifty-fifty.
Also advantageously, elastomeric element is made up of multiple parts, and wherein particularly each elastomeric element has the Connection Element of answering in contrast.So, the elastic range of supporting leg is advantageously more longer and therefore softer, and this is generally favourable in the time of engaging application (Klippanwendung).
Also advantageously, elastomeric element has domatic, when installation Connection Element in rotational motion process first with this domatic contact.So more be conducive to stop shoulder be engaged to stop rib after because Connection Element is through described domatic.In addition, in the time that rotation exceedes the straight angle, spring can be tightened, thereby makes to keep as far as possible little for card clothing frame being installed to rotatory force required on matrix.
Also advantageously, rotation latching member has positioning aid, while this two members being installed by this positioning aid, it can be positioned to unlocked position toward each other.Find correct installation site, described installation site is corresponding to unlocked position, and this process can be simplified greatly because of positioning aid.Also avoid, because Rig up error causes damage to some parts in blocking element and rotation latching member, particularly avoiding case spring supporting leg to cause damage simultaneously.Also can simplify the operation of opening roller while installation, reason is to find quickly correct installation site simultaneously.
According to another favourable form of implementation of the present invention, blocking element (particularly case spring supporting leg) or locking member (particularly locking spring legs) preferably have the fastening element working in the axial direction.Particularly advantageously, at least described case spring supporting leg is furnished with fastening element because card mounting machine chord position can protection blocking spring legs during in the position of engagement avoid dismantling at axial direction improper.Equally, such fastening element also can protection blocking spring legs avoid Rig up error, such as the axial compressive force of attempting with imposing on matrix is installed card clothing frame, but does not have in advance these two parts to be positioned to correct installation site toward each other.Can avoid thus case spring supporting leg cause wearing and tearing or damage, described wearing and tearing or the meeting of damage reduce the locking moment of torsion between matrix and card clothing frame.Therefore for the same reason also advantageously, locking member is furnished with fastening element.
The particularly advantageous form of implementation of one according to the present invention, is arranged in positioning aid on fastening element, and wherein fastening element preferably has the one or more locating holes as positioning aid.First card clothing frame and matrix are placed in the axial direction simultaneously, wherein fastening element protection Connection Element and locking member are avoided damaging for this reason, and by reversing fastening element is delivered to unlocked position relative to one another, likely correctly install at this unlocked position.Be preferably formed locating hole, for the Connection Element in conjunction with card clothing frame simultaneously.
Also advantageously, fastening element is designed to the reinforced gasket of single type, this pad has at least one first reinforcing area of at least one locking spring legs and/or at least one second reinforcing area of at least one case spring supporting leg.Especially, in the time that one or more locking spring legs and one or more case spring supporting leg are designed to the leaf spring of single type, the reinforced gasket of described single type is favourable.
According to the present invention, opening tag weaving loom has at least one rotating box, and this rotating box surrounds opening roller.As previously mentioned, the feature wherein mentioned can individualism or is existed with any combination in the design of opening roller.

Fig. 1 shows the perspective view of opening roller 1, and it has the matrix 2 and the card clothing frame 3 that are in the unlocked position.At this unlocked position, card clothing frame 3 can be in the axial direction by rotating and depart from matrix 2 along turning cylinder A.In this embodiment, card clothing frame 3 two-piece type ground form, and wherein card clothing frame has card clothing frame 4 and card clothing ring 5.But card clothing frame 3 also can form on single type ground.Matrix 2 torsionally links together and concentrates on driving shaft with the driving shaft 6 of opening tag weaving loom.Card clothing frame 3 also concentrates on driving shaft 6.Driving shaft 6 is installed in rotation on and holds in cover 7.
Matrix 2 and card clothing frame 3 are removably connected to each other by rotation latching member 8.Rotation latching member 8 is designed to quick lock part.Thus can Fast Installation and dismounting card clothing frame 3.Rotation latching member 8 designs as follows, makes the card clothing frame 3 can be by with on the rotation direction R opposite direction of opening roller 1 and be removably connected matrix with respect to the rotation of matrix 2.
Under connection status, card clothing frame 3 or card clothing frame 4 and matrix 2 be by rotation latching member 8 elastic load relative to one another, thereby the two card clothing ring 5 is seamlessly clamped substantially.Evitable like this, fiber accumulate in the join domain between matrix 2 and card clothing ring 5 or accumulate in card clothing frame 4 and card clothing ring 5 between join domain, these fibers may pollute spinning in the time of shredding.
Card clothing ring 5 is cut open with certain angular range in Fig. 1, to can see the rotation latching member 8 in this region.Rotation latching member 8 mainly has Connection Element and blocking element, is engaged with each other its bayonet type, make thus card clothing frame 3 and matrix 2 the axial direction form fit of opening roller 1 be joined to one another.In this embodiment, Connection Element is designed to the hook-shaped Connection Element 9 of in card clothing frame 3 (particularly on card clothing frame 4).In addition, blocking element is designed to the case spring supporting leg 10 on matrix 2.But selectively or extraly can imagine too, hook-shaped Connection Element 9 is arranged on matrix 2 and case spring supporting leg 10 is arranged in card clothing frame 3, particularly on card clothing frame 4.
Case spring supporting leg 10 has pedestal 11, free end 12 and is arranged in the bending area 13 between the two.Case spring supporting leg 10 is designed to flexible, the wherein case spring supporting leg direction bending toward card clothing frame 3 or card clothing frame 4 with respect to the locked position of coupler of the card clothing frame 3 of matrix 2 in the axial direction, the card clothing ring 5 between card clothing frame 3 and matrix 2 is tensioned (referring to Fig. 3 f) with elasticity load mode.
According to Fig. 1, case spring supporting leg 10(is particularly in bending area 13) have domaticly 14, hook-shaped Connection Element 9(is particularly with spring stop surface 15) in the time connecting, contact described domaticly, case spring supporting leg 10 is tensioned.
In addition, case spring supporting leg 10(is particularly in the region between free end 12 and bending area 13) there is stop shoulder 16.Stop is takeed on corresponding with the stop rib 17 of hook-shaped Connection Element 9, thereby makes card clothing frame 3 removably maintain the locked position of coupler of terminal with respect to matrix 2 by definite thus elastic force.Stop rib 17 is arranged on hook-shaped Connection Element 9 and (is positioned on the second side 19 away from case spring supporting leg 10 at it).So with being formed in Connection Element 9 presses to matrix 2 by retainer 20 on the first side 18 of Connection Element circumference retainer 21(referring to Fig. 3 f).
In order to unclamp card clothing frame 3, must overcome the elastic force threshold value definite by case spring supporting leg 10, to stop rib 17 can be spun off from stop shoulder 16.The rotatory force occurring when operation can not exceed described elastic force threshold value, thereby makes card clothing frame 3 be locked in securely locked position of coupler with respect to matrix 2 in the time of operation.
Due to wearing and tearing and/or fatigue of materials may there is following situation, be that hook-shaped Connection Element 9 can not correctly remain on locked position of coupler by case spring supporting leg 10 again, for conventionally engaging as follows at stop shoulder 16 stop rib 17 below, make the retainer 20 of Connection Element 9 near circumference retainer 21(referring to Fig. 3 f) in this position.Otherwise Connection Element 9 can slide out to the position of engagement from locked position of coupler, although be still connected to form fit with Connection Element 9 at this position of engagement case spring supporting leg 10, but have this danger, Connection Element 9 can further slide into unlocked position from this position of engagement.This may cause card clothing frame 3 to depart from from matrix 2 uncontrollably in the time of operation.But another kind of alternative case also it is contemplated that, card clothing frame 3 does not correctly turn to locked position of coupler when mounted, and only turns to the position of engagement, and wherein this situation also may cause card clothing frame 3 to depart from from matrix 2 uncontrollably.
For this reason, opening roller 1 as shown in Figure 1 has locking member, and it is preferably designed to locking spring legs 23 in the present embodiment.The purposes of described locking spring legs 23 is, in the time of operation, hook-shaped Connection Element 9 is firmly held in to the position of engagement.Hold it in latched position with definite elastic force for this reason.For Connection Element 9 or the card clothing frame 3 moving axis A that rotates being turned to unlocked position from the position of engagement with respect to case spring supporting leg 10 or matrix 2, operating personnel must overcome elastic force threshold value.
Locking spring legs 23 has pedestal 24 and free end 25.The two is provided with bending area 26.The locking spring legs 23 of Flexible Design can move in latched position with between by position.In latched position, avoid card clothing frame 3 to turn to unlocked position from the position of engagement.By position, make card clothing frame 3 turn to the position of engagement to install from unlocked position, and turn to unlocked position from the position of engagement so that dismounting.
In addition, locking spring legs 23 also has domatic 27.Described domatic corresponding with the contact zone 28 of Connection Element 9.Contact zone 28 is preferably formed in the region of end face 22 and/or in the region of the second side 19 of Connection Element 9.Contact zone 28 is designed to seamed edge herein, is preferably the seamed edge between end face 22 and the second side 19.But in another alternate embodiment, also contemplated that point-like or planar contact zone 28.
In addition, locking spring legs 23 also has overstress stops 29.The purposes of this overstress stops is in the time that latched position moves to by position, to prevent from locking spring legs 23 in locking spring legs 23 and produce plastic deformation.Overstress stops 29 is arranged in the latched position of locking spring legs 23 with interval, is particularly arranged in the domatic side away from locking spring legs.
Fig. 2 shows the perspective view of matrix 2.As can be seen from FIG., rotation latching member 8 has respectively three bases and describes before this region of engagement of designing.Case spring supporting leg 11a, 11b, 11c and locking spring legs 23a, 23b, 23c are designed to the leaf spring 30 of single type.But in unshowned alternate embodiment, each case spring supporting leg 11a, 11b, 11c also form respectively an entirety as locking spring legs 23a, 23b, 23c herein.Therefore advantageously, can make the most applicable case spring supporting leg of characteristic 11a, 11b, 11c or locking spring legs 23a, 23b, the 23c requirement separately of spring steel.
Fig. 3 a – 3f is the rough schematic view of rotation latching member 8, wherein turns to the position of engagement and further turns to the locked position of coupler of terminal from the position of engagement again from unlocked position with respect to the card clothing frame 3 of matrix 2.Card clothing frame 3 is here reduced on single hook-shaped Connection Element 9.In addition, matrix 2 is also reduced on locking spring legs 23, case spring supporting leg 10 and stopping element 31.
Fig. 3 a shows the rotation latching member 8 being in the unlocked position while beginning is installed.Now between card clothing frame 3 and matrix 2, there is no the connection of form fit at the axial direction of opening roller.Locking spring legs 23 and case spring supporting leg 10 are unloaded, wherein lock spring legs 23 and are positioned at latched position.Hook-shaped Connection Element 9 in its 18 regions, the first side in tangential direction near the pedestal 11 of case spring supporting leg 10 and be in contact with it domatic 27 near locking spring legs 23 of face 28 on axis direction, thereby card clothing frame 3 can not be rotated with respect to matrix 2.
For card clothing frame 3 is arranged on matrix 2 and must first in the axial direction card clothing frame 3 be pressed into towards the direction of matrix 2.The power that operating personnel apply simultaneously must exceed the elastic force threshold value that locks spring legs 23, thereby makes the free end 25 and/or its bending area 26 that lock spring legs 23 be pressed into shown in Fig. 3 b and to pass through position from latched position shown in Fig. 3 a.Locking spring legs 23 1 arrives it and passes through position, card clothing frame 3 or Connection Element 9 just can rotate with respect to matrix 2, simultaneously Connection Element 9 form fit ground act on case spring supporting leg 10 in the back, thereby the connection that makes to form between card clothing frame 3 and matrix 2 form fit on the axial direction of opening roller (referring to Fig. 3 b).
Due to the Flexible Design of locking spring legs 23, once the axial force therefore being applied by operating personnel is less than the elastic force threshold value that locks spring legs 23, locking spring legs will be slided and automatically be returned to latched position.Now except the power that operating personnel apply in tangential direction, also Connection Element to be pressed into the position of engagement shown in Fig. 3 c.
Fig. 3 c, 3d and 3e show the rotation latching member 8 in position of engagement different phase.In the position of engagement, between card clothing frame 3 and matrix 2, have in the axial direction the connection with gapped form fit, but card clothing frame 3 is not locked in tangential direction with respect to matrix 2.In the time of operation, automatically again move to unlocked position from the position of engagement but the locking spring legs 23 that automatically again slides into latched position prevents Connection Element 9, prerequisite is that card clothing frame 3 does not correctly turn in advance locked position of coupler shown in Fig. 3 f or makes card clothing frame automatically move to the position of engagement from locked position of coupler because case spring supporting leg 10 is beset by technical hitches.Therefore, Connection Element 9 can only come back to unlocked position shown in Fig. 3 a by the elastic force threshold value that overcomes locking spring legs 23.
For correct release rotation latching member 8 must turn to retainer in tangential direction by it.Therefore according to shown in Fig. 3 d, the first stage of the position of engagement is between Connection Element 9 and matrix 2, particularly between its stopping element 31 and case spring supporting leg 10, gapped in the axial direction.Only have in the time that card clothing frame 3 is further rotated with respect to matrix 2 as shown in Figure 3 e, the spring stop surface 15 of Connection Element 9 just contacts with domatic 14 of case spring supporting leg 10.At this moment case spring supporting leg 10 is tensioned, and makes it Connection Element 9 be pressed in the axial direction to the stopping element 31 of matrix 2.
Connection Element 9 one hook-shaped shown in Fig. 3 f is by the stop shoulder 16 of case spring supporting leg 10, and stop rib 17 just engages into stop and takes on after 16.At this moment, Connection Element 9 presses to the circumference retainer 21 of stopping element 31 in tangential direction with its retainer 20.Card clothing frame 3 is connected with matrix 2 securely at locked position of coupler.
It must be rotated as follows with respect to matrix 2 for card clothing frame 3 is disassembled, first card clothing frame returns to the position of engagement shown in Fig. 3 e to Fig. 3 c from locked position of coupler shown in Fig. 3 f.For this reason, operating personnel must overcome the elastic force threshold value of case spring supporting leg 10, thereby make the stop rib 17 of Connection Element 9 slip over the stop shoulder 16 of case spring supporting leg 10.Connection Element 9 remains on the position of engagement shown in Fig. 3 c to Fig. 3 e firmly by locking spring legs 23 now.For card mounting machine frame 3 the most at last disassembles from matrix 2, must further rotate card clothing frame 3, until the contact area 28 of the frame of card clothing shown in 3c and domatic 27 contacting of locking spring legs 23.Due to domatic 27, Connection Element 9 makes free end 25 and/or bending area 26 turn to shown in Fig. 3 b and pass through position from latched position.For this reason, must overcome the elastic force threshold value of locking spring legs 23.Thereby substantially avoid Connection Element 9 automatically to unclamp in the time of operation.Turn to unlocked position according to Connection Element 9 one shown in Fig. 3 a, locking spring legs 23 just automatically returns to latched position and card clothing frame 3 and can depart from from matrix 2.
Fig. 4 shows the alternate embodiment of the rotation latching member 8 with locking spring legs 23, and this rotation latching member 8 has outlet area 32 in its free end 25 regions.Preferably, outlet area 32 has been designed to curvature.This is conducive to skid off better in the time of dismounting Connection Element 9.
Similar with Fig. 3 a – 3f illustrated embodiment, domatic 27 of locking spring legs 23 tilts with α angle in the direction of matrix 2 towards pedestal 24.Elasticity threshold value by the material behavior that locks spring legs 23 with and length and the gradient of bending area determine, Connection Element 9 be moved to unlocked position from the position of engagement and must overcome described elasticity threshold value.Shown in Fig. 4, outlet area tilts with β angle in the direction of matrix 2 towards pedestal 24.Compared with β angle, α angle is designed to be less.
Fig. 5 shows the alternate embodiment of case spring supporting leg 10.Similar with previous embodiment, the profile of the first side 18 of Connection Element 9 is identical with the side 34 of case spring supporting leg 10 in pedestal 11 regions.Can limit thus the accurately position of engagement of Connection Element 9 with respect to case spring supporting leg 10.
But be different from previous embodiment, the supporting leg of case spring shown in Fig. 5 10 has ingate/outlet opening 33.This hole forms and for introducing and derive hook-shaped Connection Element 9 in pedestal 11 regions.Advantageously, ingate/outlet opening 33 is only slightly bigger than the hook-shaped Connection Element 9 of answering in contrast, slides into the risk of unlocked position because can reduce in addition like this Connection Element 9 in when operation from the position of engagement.Therefore, Connection Element 9 rotates in ingate/outlet opening 33 regions just, and this probability is quite low.To expect on the contrary, when described blocking element rotates through the top of ingate/outlet opening 33 and reach the end away from the pedestal 11 of bending area 13.In this position, between Connection Element 9 and case spring supporting leg 10, still there is being connected of form fit, thereby card clothing frame 3 can not be departed from from matrix 2 in the axial direction.
Fig. 6 shows the cutaway view of matrix 2, and described matrix is also provided with positioning aid 36 and fastening element 35 in addition.The matrix 2 in addition with case spring supporting leg 10 and locking spring legs 23 is equal to matrix shown in Fig. 2 substantially, and making can be with reference to the form of implementation of earlier drawings.Therefore difference with form of implementation shown in earlier drawings is only discussed hereinafter.
In this example, case spring supporting leg 10(has 3 herein), and locking spring legs 23(also has 3 herein) all with the form design of the leaf spring 30 of single type.Leaf spring 30 is covered by the fastening element 35 of the reinforced gasket that is designed to single type.Fastening element 35 has positioning aid 36 simultaneously, and card clothing frame 3 can turn to unlocked position with respect to matrix 2 by this positioning aid, to can correctly install.Positioning aid 36 has three locating hole 36a herein, and these holes are designed to the axial intercept of fastening element 35.Meanwhile, locating hole 36a accurately arranged and matched with the size of the Connection Element 9 of card clothing frame 3 at unlocked position, and and Connection Element acting in conjunction in the correct location of two members 2,3.Therefore card clothing frame 3 in axial direction can be placed in to matrix 2 when installing, and then rotate card clothing frame until Connection Element 9 almost slips into locating hole 36a automatically.So, matrix 2 and card clothing frame 3 are positioned at unlocked position (this unlocked position is corresponding to correct installation site) now toward each other, and the two are combined by the mode of having described by lasting axial compressive force.
Even if show particularly advantageous form of implementation here, in described form of implementation, positioning aid 36 is arranged on fastening element 35, but still has likely, and positioning aid 36 is designed to separate with one or more fastening elements 35.In addition, positioning aid 36 also not necessarily will be designed to locating hole 36a, but can have equally position block or analog.
Fastening element 35 is designed to the reinforced gasket of sheet material material here and offsets in the axial direction wrong assembly force and wrong removal force.Just there are wrong installation or removal in this situation below, i.e. matrix 2 and card clothing frame 3 relative to each other motion in the axial direction in installation process or unloading process, but do not locate toward each other at its unlocked position.Fastening element 35 has three the first reinforcing area 35a simultaneously, and these regions are furnished with respectively locking spring legs 23 and the supporting leg away from card clothing frame 3 one sides is covered.If opening roller 1 is installed by wrong now, can prevent from locking spring legs 23 cause damage or prevent from locking spring legs 23 bendings by fastening element 35 or reinforcing area 35a.
In addition, fastening element 35 has three reinforcing area 35b, and these regions at least cover the pedestal 11 of case spring supporting leg 10.The second reinforcing area 35b here extends beyond the four corner of case spring supporting leg 10.Same as described in just locked before this spring legs 23 thus, reinforcing area protection blocking spring legs 10 is avoided infringement in the time of Rig up error.Equally, fastening element 35 can be reinforced case spring supporting leg 10 in following situation, when card clothing frame 3 is positioned at the position of engagement and directly out attempts from the position of engagement to carry out improper dismounting at axial direction.At this moment by case spring supporting leg 10 be fixed on fastening element 35 and stop thus it to be moved further backward, can prevent that case spring supporting leg 10 is bending and it is caused damage.The reinforced gasket that substitutes the single type of having described can be imagined certainly, and at least one or more case spring supporting leg 10 is furnished with respectively the fastening element 35 of oneself.
As can be seen from Figure 6, fastening element 35 has other axial intercept, and these intercepts form installing auxiliary part 38, for fastening element 35 being correctly positioned to matrix 2 opposites in the time that it is installed.Here installing auxiliary part 38 or other axial depression are corresponding with the circumference retainer 21 of matrix 2.The profile of the pedestal 24 of locking spring legs 23 also can build in the same way, thereby makes itself and circumference retainer 21 use form installing auxiliary part 38 with regard to the described that mode of fastening element 35 above.Therefore can leaf spring 30 and fastening element 35 be placed on driving shaft 6 and by this circumference retainer 21 and correctly be located by simple mode.
In addition fastening element 35 also has other through hole 39, for for example accessible herein without the bearing of matrix 2 or other built-in element being shown or for realizing other function.For the ease of matrix 2 and card clothing frame 3 are transferred to the position of engagement and conversely from unlocked position, advantageously, fastening element 35 at least has the consolidation effect being weakened in pedestal 11 regions of case spring supporting leg 10.For this reason, to place as follows through hole 39 herein, be weakened and only leave thin plate 37 even if must be used for the reinforcing area 35b of case spring supporting leg 10 in pedestal 11 regions.This can make fastening element 35 flexibly flexible in the axial direction, so that reverse.
Last Fig. 7 shows the detail view of rotation latching member 8, and the card clothing frame 3 wherein with Connection Element 9 is positioned at the unlocked position with respect to matrix 2.As described in the embodiment of Fig. 5, the profile of the first side 18 of Connection Element 9 is identical with the side 34 of case spring supporting leg 10 herein.For this reason as described, determined the accurate position of engagement with respect to the Connection Element 9 of case spring supporting leg 10.Now also can make the 40(Ci side, side of fastening element 35 away from the Connection Element 9 being in the unlocked position by same mode) there is the profile consistent with the side 18 of Connection Element 9, thus effect is herein strengthened.
In addition, because fastening element 35 can make the structure of Connection Element 9 simpler, because the retainer 20 of Connection Element 9 can directly be made up of side 18 now.The wearing and tearing of contact site because the side 18 of Connection Element 9 contacts with 34 of the sides of case spring supporting leg 10, and also contact with 40 of the sides of fastening element 35 if necessary, so can reduce on side 18,34 and 40.This also contributes to increase the locking moment of torsion between matrix 2 and card clothing frame 3.
The present invention is not limited to the embodiment that illustrates and describe.Also likely within the scope of claim, modify, such as Feature Combination is got up, even if these features are to describe and describe in different embodiment.Therefore card clothing frame can be separately or complementally or is alternatively had the whole above-mentioned feature of matrix with any combination.Matrix is also like this conversely.
