Description
- This invention concerns a device for attaching a shaft in a frame.
- Generally, this invention is meant to be used in various applications, particularly to attach a beam in a weaving installation, either a warp beam or a cloth roll in a weaving machine, or a cloth roll in a separate take-up apparatus.
- As is known, for the bearing of a cloth roll or warp beam, square shaft ends are used which act on square openings in the bearing. In order to apply the beam on the one hand and remove the beam on the other hand, it must be moved sideways, which is a cumbersome action.
- Other devices, whereby the cloth roll or the warp beam are laid or rolled in a bearing shell, after which the bearing is closed by means of a bearing lid, are also applied frequently.
- All these known devices have the disadvantage that they require additional interventions and that it is sometimes necessary that these interventions are performed by more than one person.
- They also have the disadvantage that the operations require the use of tools.
- It is particularly necessary for the automatic application and removal of the cloth roll that the number of operations to be performed remains limited, such that they can be performed by means of a simple mechanism.
- The present invention concerns a device for attaching a shaft in a frame which does not have the above-mentioned disadvantages. More particularly, the invention aims a device to allow both the manual and automatic application of the shaft in the frame, whereby a lock is automatically provided in order to secure the shaft.
- To this end, the invention concerns a device for attaching a shaft in a frame, characterized in that it essentially consists of at least two supports to carry the shaft at its ends on the one hand, and at least at one support a lock which in its closed position keeps the shaft in place on its support while it can turn locally, and a hinged blocking mechanism for the lock.
- Preferably, the lock consists of a rotatable arm which is attached to the frame in a turnable way, and which can be taken up to the shaft end of the above-mentioned shaft, while the hinged blocking mechanism is formed by two arms which form a toggle mechanism.
- In order to better explain the characteristics of the invention, by way of example only and without being limitative in any way, the following preferred embodiments are described with reference to the accompanying drawings, where:
- fig. 1 shows a weaving machine which uses a device according to the invention for the attachment of the cloth roll;
- figs. 2, 3 and 4 show a device according to the invention in various positions:
- fig. 5 shows a schematic representation of another special position;
- figs. 6 to 10 show a variant in various positions;
- fig. 11 shows another variant.
- Fig. 1 shows a schematic representation of a weaving machine, whereby, in order to attach removable shafts such as a
cloth roll 1,devices 2 can be used as described below. - According to the invention, the above-mentioned
devices 2 consist in this case essentially of, on the one hand, at least two supports 3, such as bearings, to carry theshaft 1 at itsends 4, and on the other hand, at least at onesupport 3, alock 5 which in its closed position keeps theshaft 1 in place on itssupport 3, and a hingedblocking mechanism 6 for thelock 5. - The
lock 5 is formed by a rotatable arm, which is attached by means of afulcrum 7 to a support 8, which is mounted on the frame 9 of the machine concerned or constructed in one part thereof. This rotatable arm is situated on such a place that, when theshaft 1 is applied in thesupport 3, it can be taken up to theshaft end 4, thus preventing theshaft end 4 to leave thesupport 3. - The
support 3 is hereby constructed in two parts and consists of abottom part 10 which is fixed to the frame 9, and amovable part 11 in the form of a lid, which is attached to thelock 5. - The hinged
blocking mechanism 6 preferably consists of twoarms arms fulcrum 14. Thearm 12, for that matter, is hinged to the support 8 by means of afulcrum 15, while thearm 13 is also connected with thelock 5 by means of afulcrum 16. Thearms fulcrums line 17, such that a locked position of the toggle mechanism is defined. This position is hereby determined by a preferablyadjustable stop 18 which is mounted on the support 8. - The
stop 18 may be placed, respectively set, such that the fulcrum between thearms line 17, particularly to its right, indicated by 14A in fig. 2. This has the advantage that a stable position of thearms - The hinged
blocking mechanism 6 can be folded together in the other direction, such that thelock 5 can be turned round thefulcrum 7 and thesupport 3 is consequently opened. - Preferably, the device is equipped with pressing means which force the hinged
blocking mechanism 6 in the above-mentioned locked position, and which consist of, for example, a spring, such as atorsion spring 19, mounted round ashaft 19A on the support 8, and pressing against thearm 12 with a free end, such that the latter is forced against thestop 18. - The device preferably also has means which allow to activate the hinged
blocking mechanism 6, in order to open thelock 5. - These means can in the first place consist of a
handle 20 by which theblocking mechanism 6, particularly thearms lock 5 can be opened manually. Thehandle 20 preferably makes up part of the above-mentionedarm 13 and is at an angle in relation to the connection line between thefulcrums - According to a variant, or possibly in combination with the description above, the means which allow to activate the hinged
blocking mechanism 6 can also consist of an element which can be moved by means of ashaft 1 presented to the device, such that thelock 5 is opened. - In the embodiment shown, the above-mentioned element is formed by a
protruding part 21 of thearm 13, such that thispart 21 is situated above a supportingplane 22, over which theshaft 1 can be rolled to thebearing 3, and whereby thepart 21 is situated in the path of theshaft 1. - The supporting
plane 22 may have arecess 23 or similar, in which ashaft 1 can be placed in waiting position at itsends 4. - Preferably, the
bottom side 24 of thelocking element 5, in other words, the side which rests on the supportingplane 22, has a rounded form, such that theshaft end 4 can easily pass underneath thelocking element 5. - The
arm 13 preferably has acam 25, whose aim will become apparent from the description below. - The working of the device can be easily deduced from the figs. 2 to 5.
- Fig. 2 shows the device in rest position, whereby a
shaft 1, such as a cloth roll, is placed in the support or bearing 3. Thetorsion spring 19 keeps the hingedblocking mechanism 6 in such a position that thefulcrums lock 5 cannot possibly be moved upward at thefulcrum 16, so that thesupport 3 remains closed. - Fig. 3 shows the situation when the
shaft 1 is applied manually or automatically, whereby it must only be pushed over the supportingplane 22. Hereby it first makes contact with the above-mentionedpart 21, as shown by the dashed line in fig. 2, such that theblocking mechanism 6 and thelock 5 are opened, such that theshaft 1 can be slid in thesupports 3 unhindered. - In order to remove the
shaft 1 from thesupport 3, thelock 5 can be opened manually by tilting thehandle 20 according to arrow A, such that a situation is created, as shown in fig. 4, whereby theshaft ends 4 can pass freely underneath thelock 5. - Preferably, the
fulcrums arms lock 5 are constructed such that when thehandle 20 is pulled down completely, thearm 13 and thelock 5 are toggled round thefulcrum 16 until the whole comes in contact with astop 26, for example formed by the edge of the support 8. As a result, theblocking mechanism 6 remains in a stable deactivated position, as is represented schematically in fig. 5. - When the
shaft 1 is removed from thesupports 3, the former is pushed over the supportingplane 22, whereby it makes contact with the above-mentionedcam 25, such that theblocking mechanism 6 is activated and thetwin support 3 is closed again. - When the
shaft 1 is automatically removed, as indicated in fig. 2, apushing mechanism 27 exerts a force F on thepart 21 in order to bring theblocking mechanism 6 in its non-blocking position, before theshaft 1 is removed from thesupports 3, sliding over the supportingplanes 22, by means of suitablemovable arms 28 or similar. - In order to be able to work with
shaft ends 4 of various thicknesses or to set the play or the prestress of the gripping force of thelock 5 on theshaft end 4, an adjustable eccentric 29 is preferably mounted in thefulcrum 15, so that thefulcrum 15 can be shifted. - The setting of the
stop 18 also allows thepart 11 of thesupport 3 to come loose from theshaft end 4, such that theshaft 1 is locked but can still turn. - Figs. 6 to 10 show a variant whereby the hinged
blocking mechanism 6 consists of only one arm, particularly in the form of alever 30. - The
lock 5 hereby also consists of an arm which can turn round ahinge point 7. The connection between thelever 30 and thelock 5 consists of ahinge clutch 31 which provides a well-defined play such that thelever 30 and thelock 5 act on one another by means of a pin slot clutch. Thelever 30 can be turned round afulcrum 32 which is situated fixed to the frame and is charged by means of aspring 34 or similar at theend 33 which is situated opposite thehinge clutch 31, such that thelock 5 is pressed in its locked position, whereby in this position thefulcrum 32, theshaft 1 and the centre of thehinge clutch 31 are almost in oneline 35. - The
end 33 has ahandle 36 and, at its underside, acam 37, whose aim will become apparent from the description below. - Between the
fulcrum 32 and the hinge clutch 31 astop 38 is provided against which anelement 39, such as an arm for removing theshaft 1, can be presented to move thelever 30 against the force of thespring 34. - The
lock 5 also has apart 40 which can operate in conjunction with an adjustable stop 41, in order to avoid that themovable part 11 exerts a frictional force on theshaft end 4. Thepart 40 can also operate in conjunction with a flexiblybendable stop 42, such that when thepart 40 is moved past this stop, thelock 5 cannot be moved back by the force of thespring 34. - The supporting
plane 22 over which theshaft 1 can be supplied is preferably placed horizontally. It is clear that the above-mentionedelements 39 for supplying and removingshafts 1 are provided with suitable driving means to move these horizontally and vertically, and to take up ashaft 1, such as a cloth roll or a warp beam, particularly as described below. - The working of the device according to fig. 6 can be easily deduced from the figs. 6 to 10.
- Fig. 7 shows the application of a
shaft 1 in thesupport 3. Hereby theshaft 1 is pushed forward over the supportingplanes 22, situated underneath theshaft ends 4, by exerting a horizontal force on it by means of the above-mentionedelements 39. The shaft ends 4 hereby slide underneath thelever 30 and thelock 5, whereby the latter are pressed aside conveniently. - Removing the
shaft 1 is done by deblocking theblocking mechanism 6, for example by exerting an upward pressure on thestop 38 by moving theelement 39, respectively theelements 39, upward until a position is reached as indicated in fig. 8. Then theshaft 1 can be pulled out of thesupport 3 by moving theelements 39 to the left, whereby the shaft ends 4, however, keep resting on the supporting planes 22. - If the
shaft 1 is removed manually, i.e. without using the above-mentionedelements 39, thelever 30 is pulled down at theend 33 until a position is reached as shown in fig. 9, whereby thelock 5 is opened and is held behind thestop 42. Then theshaft 1 can be slid out of thesupport 3 over the supporting planes 22. - When the
shaft 1 is removed either manually or automatically, thelock 5 is closed again, after theshaft 1 has been removed, as the shaft ends 4 act on the cam, respectivelycams 37, and theend 33 is moved up until thespring 34 keeps the whole in a closed position again, as indicated in fig. 10. - Fig. 11 shows a variant whereby on the
blocking mechanism 6, particularly on the above-mentionedarm 12, a stop 43 is applied which is situated such that the device is opened when an upward pressure is exerted on said stop 43. - This stop 43 allows the device to be opened by a
movable element 44 which exerts a pressure on the stop 43. As indicated in fig. 11, thismovable element 44 may consist of a transport arm in order to remove theshaft 1 from thesupports 3, whereby the upper side 45 makes contact with the stop 43 when the transport arm is presented to theshaft 1. - The present invention is in no way limited to the embodiments described by way of example and shown in the drawings; on the contrary, such a device can be made in various shapes and dimensions while still remaining within the scope of the invention.
