Mechanism may move.It can clamp and remove jointly or be attached the multiple clampers or doffer clamper of spool or ceases to be busy bobbin again
On doffer bar.Single clamper is preferably can be pneumatically actuated, and the clamping element including iris-diaphragm, the clamping
Element can be worked by compressed air and be taken in spool or spool pipe, and then by introducing compressed sky
Gas clamps spool or spool pipe.In order to make single clamper work by compressed air, the pipe of compressed air is supplied
Road is located in doffer bar, is directed to the single barrier film of clamper via supply line respectively from the compressed air of doffer bar.
The Y of CN 2 873 813 describe the clamper with this design.Clamper has for accommodating spool or spool
The cylindrical holding element of pipe.The clamping element for the diaphragm of rubber form that can be adjusted via pneumatic means is located in holding element
On wall.Using barrier film, the outside grasping of the end of spool that can be from the inside for being inserted into holding element or spool pipe.Barrier film
Holding element is fixed to via direction of two closing caps along longitudinal axis, a closing cap is located on bottom side, another closing
Lid is on the top side of holding element.Two closing caps are clamped to holding element via buckle-type connection.Clamper includes being used for
It is fastened to the tightening member of doffer bar.Tightening member is fixedly connected to holding element, and including for being supplied to barrier film
The air duct of compressed air.Tightening member has hook in its top side, in the flexible holding tab in its bottom side.Clamper is passed through
Container is fixed to by hook, and via elastically keeping in the locking groove that tab is fixed on doffer bar.In the A1 of EP 0303877
Describe the clamper with similar Design.Compared with above-mentioned clamper, the tightening member of clamper is in its bottom side and top side
Upper flexible holding tab.Tab is elastically kept by two, clamper can depart from and be removably attached to doffer bar
On two parallel locking grooves in.Locking groove allows multiple single clampers to be fastened along doffer bar.
When replacing spool or spool pipe, barrier film is worked via air duct by compressed air.As a result, barrier film exists
Shunk in holding element, and spool or spool pipe are grasped from outside in its end region.In order to discharge the line in holding element
Cylinder or spool pipe, the pressure of barrier film is mitigated by interrupting compressed air.Continuous due to the stress on barrier film is alternately applied
Plus and mitigate and barrier film against spool or the frictional force of spool pipe, barrier film weares and teares after certain operation time period.Wear tables
Now become porous for barrier film, and be not airtight in some positions.As a result, no longer ensure that spool or the safety of spool pipe are replaced
Change., it is necessary to replace the barrier film of abrasion with new barrier film after certain operation time period.
One of described clamper significantly has the disadvantage that the barrier film worn and torn with new membrane replacement is comprising a considerable amount of
Effort.In order to replace barrier film, operator must remove clamper from doffer bar first.Therefore, for from CN 2873813
Y clamper, hook is removed from the container in doffer bar, and elastically keeps tab from locking groove release, or for from
The A1 of EP 0303877 clamper, two elastically keep tab from two parallel locking groove releases.Doffer device it
Outside, then upper closing cap and lower closing cap are removed from holding element.Then the barrier film of abrasion is separated with holding element, be used in combination

Part, and clamper is arranged on doffer bar.Due to the design of clamper, the barrier film for replacing abrasion be it is very laborious, because
It must be removed for whole clamper from doffer bar.Therefore, the long downtime that barrier film includes spinning machine is replaced.Further, since
Frequent assembly and disassembly of the clamper on doffer bar, the tab that elastically keeps of clamper is unnecessarily worn and torn.As a result,
It cannot ensure to elastically keep enough clamping effects in locking groove of the tab on doffer bar.
The content of the invention
The purpose of the present invention is this shortcoming for eliminating known clamper.
It is that holding element is maintained on tightening member by retaining element according to the purpose of the realization of the present invention.Via
Retaining element, holding element is secured transverse on tightening member relative to the longitudinal axis of holding element.With the folder of prior art
Holder is compared, and tightening member and holding element are separated each other, i.e. tightening member and the holding element part that to represent two different.Cause
This, in order to replace clamping element, clamper must no longer be removed from doffer bar.But, clamper can be stayed in doffer
On bar, and by dismantle retaining element by holding element together with clamping element from tightening member remove.Then can be simple
The clamping element of abrasion is replaced with new clamping element in ground.Therefore, during clamping element is replaced, the downtime of spinning machine protects
Hold relatively low.In addition, preventing the unnecessary abrasion for elastically keeping tab on tightening member.Falling so that it is guaranteed that elastically keeping tab
Enough clamping effects on yarn machine bar.
In addition, when retaining element partly surrounds the outer wall of holding element or partly installs outer wall against holding element
When, it has proved that it is favourable.This ensures that element is fully held and locate on tightening member.Therefore, except fastening
Outside element, retaining element is also represented by a part for the housing of clamper.Retaining element advantageously surrounds the outer wall of holding element
180 ° and 270 ° between.
When retaining element is connected to tightening member via buckle-type, it is also advantageous.As a result, retaining element is easy
Separated with tightening member, and holding element together with clamping element therefore, it is possible to rapidly being removed from tightening member.Buckle-type
Connection is designed so that tightening member has projection, and retaining element has the raised recess of encirclement.Conversely, however,
It can make retaining element that there is projection, and make tightening member that there is the recess for surrounding projection.
In addition, when clamping element at least one of the end of clamping element along the direction of longitudinal axis via clamping member
The Part I region of periphery of the part above tightening member, and of periphery via clamping element above retaining element
It is favourable when two subregions are fixed to holding element.When at two ends（I.e. at the lower end and upper end of holding element）'s
Clamping element or barrier film, along the direction of the longitudinal axis of holding element, via clamping element or barrier film above tightening member
The Part II region of the Part I region of periphery and the periphery via clamping element or barrier film above retaining element is consolidated
When arriving holding element surely, it is also advantageous.Compared with prior art, therefore eliminate for clamping element to be axially fixed into guarantor
Hold two closing caps of element.In order to realize clamping element to enough axial restraints of holding element, it has proved that work as clamping
Element via 180 ° of tops in the periphery of clamping element tightening member and via on 180 ° of the periphery of clamping element
It is favourable when the retaining element of side is fixed to holding element.
