Description
- The invention relates to a device for holding a shaft end, wherein the device comprises a first bearing element and a bearing element movable relative thereto that can move between a holding position in which the shaft end is held and a release position in which the shaft end is free. The shaft end can be part of a warp beam or a cloth beam for a weaving machine.
- Such a device is for example known from
EP 414 291 A1 -
JP 4-37293 -
US 2,514,152 relates to a releasable bearing for a weaving machine comprising two lower rollers with stationary pivot axes and upper rollers mounted on movable arms actuated by locking cams. The rollers are all adapted to be moved into engagement with annular gudgeon grooves provided at a warp beam roll and/or a cloth beam roll. - An object of the invention is to form a simply constructed device of the above-mentioned type that is reliable and easy to operate.
- This object is achieved by a device for holding a shaft end, which is part of a cloth beam or a warp beam for a textile machine, with the features of
Claim 1. Preferred embodiments are defined in the dependent claims. - To achieve this object the device according to the invention comprises a pivotably mounted lever, a first stationary arranged bearing element and a movable bearing element attached to a pivotably mounted arm having a running surface that cooperates with the running surface of the lever to bring the arm in the holding position, wherein the running surface of the arm cooperates with the running surface of the lever to hold the arm in the holding position, and wherein the running surfaces of the arm and the lever are embodied in such a way that forces acting in radial direction on the shaft end cannot cause the movably mounted bearing element, together with the pivotably mounted arm, to be moved out of the holding position.
- The device can be easily operated by means of the lever that can interact with the arm. The profiled or cam-shaped running surfaces of the arm and the lever are embodied in such a way that forces acting in radial direction on the shaft end cannot cause the movably mounted bearing element, together with the pivotably mounted arm, to be moved out of the holding position. Only when the lever is moved out of its holding position the arm with the movably mounted bearing element can also leave the holding position. Through the interaction between the running surface of the arm and the running surface of the lever, the arm can be brought into and held in the holding position.
- According to one embodiment, the running surface of the arm and the running surface of the lever that cooperates with the running surface of the arm are arranged in such a way that when the lever is moved out of the holding position, the force between the lever and the arm first increases and with further movement decreases again. This means that the arm and the lever can hereby form an over-center mechanism while they are in the holding position. This is advantageous for holding the pivotably mounted bearing element in the holding position. Both the lever and the arm can hereby deform elastically during the movement from and to the holding position. As a result, an over-center mechanism is formed with the running surfaces of the arm and of the lever that allows the arm to be held in the holding position.
- According to one embodiment, the distance between a pivot of the lever and a contact point, in which the running surface of the arm contacts the running surface of the lever in order to reach the holding position is larger than a tangential distance between the pivot and the running surface of the arm, so that the running surface of the arm and the running surface of the lever cooperate to form an over-center mechanism.
- According to one embodiment, the arm and the lever are connected by a spring. This allows among other things the arm to follow the lever when commanded by the lever even when the running surfaces of the arm and the lever are not interacting with one another. The spring also allows to hold the arm in the holding position and allows to force the arm and the lever towards one another. The spring can hereby be installed between the lever and the arm in such a way that when the lever is moved out of the holding position, the force of the spring between the lever and the arm first increases and with further movement decreases again. This allows the arm and the lever to be pulled towards one another in the holding position, and allows that the arm and the lever may be in a so-called over-center position in the holding position by the spring. An over-center mechanism that allows the arm to be held in the holding position is thus formed with the spring.
- According to one embodiment, the spring is installed between an element attached to the arm and an element attached to the lever, wherein a line through the axis of the element attached to the arm and the axis of the element attached to the lever moves past a line through the axis of the element attached to the arm and the axis of the held shaft end in order to reach the holding position.
- According to one embodiment, a stop on the lever and a stop on the arm may make contact with one another in the holding position. This allows the relative positions of the arm and the lever in the holding position to be determined without the need for further elements.
- According to one embodiment, the device comprises a frame to which the arm and the lever are attached by means of a corresponding pivot with the pivot for the arm and the pivot for the lever being installed parallel to the held shaft end. This is advantageous for holding the shaft end in the device.
- The invention also relates to a weaving machine that comprises a device according to the invention.
- Further characteristics and advantages of the invention are presented in the following description of the embodiments shown in the drawings.
-

Figure 2 shows a side view along arrow F2 infigure 1 of the device infigure 1 with a shaft end held in the holding position. -
Figure 3 shows a side view along arrow F3 infigure 1 of the device infigure 1 with a shaft end held in the holding position. -
Figure 4 shows the side view offigure 3 in a position between the holding position and the release position. -
Figure 5 shows the side view offigure 3 in the release position. -
Figures 1 to 5 show adevice 1 according to the invention comprising aframe 2 to which abearing 3, also referred to as a bearing device, is attached. Thisframe 2 can be attached to or form part of a side section of a weaving machine. Close to the bearing 3 asupport surface 4 is arranged to guide ashaft end 5 to be held to thebearing 3. Theshaft end 5 hereby forms the part to be held in the bearing and can be a part of a warp beam, a cloth beam or an element for a weaving machine or for a textile machine. The bearing 3 of thedevice 1 for holding theshaft end 5 comprises a first stationary arranged bearingelement 6 and a second movably arranged bearingelement 7 that is moveable relative to the stationary installedbearing element 6. Thebearing element 7 is hereby moveable between a holding position in which theshaft end 5 is held in thebearing 3, and a release position in which theshaft end 5 is free in the area of thebearing 3, this means it is not held in thebearing 3. - The
bearing element 6 is installed in theframe 2 in the area of the angle between the horizontally arrangedpart 8 and the vertically arrangedpart 9 of theframe 2. Thebearing element 6 can be glued, clamped, welded or fastened by another known means to theframe 2. In the embodiment shown, thebearing element 6 is essentially formed by a cylinder segment that connects with thesupport surface 4 substantially tangentially. This may allow theshaft end 5 to be mounted in thebearing element 6 or to be removed from thebearing element 6. Thesupport surface 4 can consist of a plastic element, can be fastened by means of screw connections to thepart 8 of theframe 2 and extends substantially parallel to thepart 8. - The movable bearing
element 7 is attached to a pivotably mountedarm 10. Thearm 10 is attached to thepart 9 of theframe 2 by means of apivot 11. Thepivot 11 for thearm 10 is installed parallel to theshaft end 5 to be held. On the side facing towards the movably arranged bearingelement 7, thearm 10 has a runningsurface 12 with a profiled or cam-shaped form. Thebearing element 7 may be attached to thearm 10 by means ofbolt connections 13. Thebolt connections 13 comprise for example a bolt that extends with certain play through a bore in thearm 10 and a bore in thebearing element 7, whereby the bolt cooperates with a nut to attach thearm 10 to thebearing element 7. Thepivot 11 can be formed by abolt 14 that extends with limited play through a bore in thearm 10 and can be screwed into apart 9 of theframe 2. - The
device 1 also comprises a pivotably mountedlever 15, also referred to as holding arm. Thelever 15 is connected via apivot 16 to acollar 17 of thepart 9 of theframe 2. Thepivot 16 for thelever 15 is arranged parallel to theshaft end 5 to be held. Thepivot 16 is hereby also installed parallel to thepivot 11 for thearm 10. - The
lever 15 is provided with a runningsurface 18 with a profiled or cam-shaped form. The runningsurface 12 of thearm 10 and the runningsurface 18 of thelever 15 cooperate with one another and allow thearm 10 to be brought into and held in the holding position by means of thelever 15. Thepivot 16 can be formed by abolt 19 that extends with a limited play through a bore in thelever 15 and can be screwed into thepart 9 of theframe 2. - The
device 1 also comprises aspring 20 that may connect thearm 10 and thelever 15. Thespring 20 can force thearm 10 and thelever 15 towards one another. Thespring 20 may be embodied by a spring system or spring element and consists of a tension spring in the embodiment shown. Thespring 20 is hereby installed between anelement 21, for example a bolt, attached to thearm 10 and anelement 22, for example a bolt, attached to thelever 15. Thelever 15 has astop 23 that may interact with astop 24 on thearm 10. Thestop 23 and thestop 24 are intended to contact one another in the holding position. The relative positions of thebearing element 6 and thebearing element 7 in the holding position may be regulated by making use of the play in thebolt connections 13 with which thebearing element 7 is attached with respect to thearm 10. With a relative positioning of thestops shaft end 5 is held or clamped in thebearing 3 may be set by adjusting the relative positions of thebearing element 7 and thearm 10. The stops 23, 24 also allow theshaft end 5 to be held in thebearing 3 in such a way that theshaft end 5 may be locked with a certain play and, for example, can still turn in thebearing 3. - The
lever 15 comprises alever arm 25 that in the holding position can extend substantially parallel to thesupport surface 4. Thelever arm 25 enables an operator to move thelever 15 and thearm 10 from holding position to release position and from release position to holding position. For this purpose, thearm 10 and thelever 15 can be elastically deformable and/or mounted in an elastically deformable manner. In the embodiment shown, the surface of thestop 23 is positioned substantially perpendicularly on the lower surface of thelever arm 25. - The running
surface 12 of thearm 10 and the runningsurface 18 of thelever 15 that cooperates with the runningsurface 12 of thearm 10 are arranged in such a way that when thelever 15 is moved from the holding position as shown infigure 2 , the force between thelever 15 and thearm 10 first increases and with further movement decreases again. This is achieved in that the runningsurface 12 and the runningsurface 18 are hereby able to form an over-center mechanism, more particularly in that the distance alongline 26 infigure 2 between thepivot 16 and thecontact point 27 where the runningsurface 12 makes contact with the runningsurface 18 is larger than the tangential distance alongline 28 between thepivot 16 and the runningsurface 12. - The
spring 20 is hereby preferably arranged between thelever 15 and thearm 10 in such a way that when thelever 15 is moved out of the holding position, the force of thespring 20 between thelever 15 and thearm 10 first increases and with further movement decreases again. This is achieved in that infigure 3 theline 29 through the axis of theelement 21 and the axis of theelement 22, which determines the position of thespring 20, moves past theline 30 through the axis of theelement 21 and the axis of the heldshaft end 5 in order to reach the holding position as shown infigure 3 , and in this way an over-center mechanism is formed. - During the movement from the release position shown in
figure 5 via the position shown infigure 4 to the holding position shown infigure 3 , the runningsurface 12 makes contact with the runningsurface 18, as a result of which thearm 12 is moved to the holding position by thelever 15. During the movement of thelever 15 from the holding position via the position infigure 4 to the release position, thearm 12 is moved together with thelever 15 by means of thespring 20. - It is obvious that for holding a warp beam or a cloth beam on a weaving machine, two
devices 1 according to the invention are preferably provided, each of which can hold ashaft end 5 of the warp beam or the cloth beam. According to a variant not shown, thelever arm 25 may form an angle with thesupport surface 4 to allow to guide ashaft end 5 between thelever arm 25 and thesupport surface 4 towards thebearing 3. - The
arm 10 and thelever 15 may be formed, for example, by a profiled plate. The edges of such a profiled plate may hereby form a runningsurface arm 10 and thelever 15 as a plate permits a simple construction, and in particular allows a running surface to be made in a simple manner. - The device according to the invention also offers the advantage that no tools are required to open or to close the
device 1. Furthermore, thedevice 1 mainly comprises an easily manufacturable pivotably mountedarm 10 for abearing element 7, an easily manufacturable pivotably mountedlever 15 and aspring 20. - The device according to the invention may be applied in different types of machines, such as textile machines, in particular in any type of weaving machine or similar textile machine comprising a part designed to be held at the shaft ends such as a warp beam or a cloth beam. This may be either an airjet weaving machine, a rapier weaving machine, a water jet weaving machine, a projectile weaving machine, some other type of weaving machine, a beaming machine, a knitting machine or some other type of textile machine.
