Definitions

  • This invention concerns a device for attaching a shaft in a frame.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 the shaft 1 at its ends 4, and on the other hand, at least at one support 3, a lock 5 which in its closed position keeps the shaft 1 in place on its support 3, and a hinged blocking mechanism 6 for the lock 5.
  • the lock 5 is formed by a rotatable arm, which is attached by means of a fulcrum 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 the shaft 1 is applied in the support 3, it can be taken up to the shaft end 4, thus preventing the shaft end 4 to leave the support 3.
  • the support 3 is hereby constructed in two parts and consists of a bottom part 10 which is fixed to the frame 9, and a movable part 11 in the form of a lid, which is attached to the lock 5.
  • the hinged blocking mechanism 6 preferably consists of two arms 12 and 13 which form a toggle mechanism, whereby these arms 12 and 13 are mutually coupled to one another by means of a fulcrum 14.
  • the arm 12, for that matter, is hinged to the support 8 by means of a fulcrum 15, while the arm 13 is also connected with the lock 5 by means of a fulcrum 16.
  • the arms 12 and 13 are hereby arranged such that the three fulcrums 14, 15 and 16 can at least be put in one line 17, such that a locked position of the toggle mechanism is defined. This position is hereby determined by a preferably adjustable stop 18 which is mounted on the support 8.
  • the stop 18 may be placed, respectively set, such that the fulcrum between the arms 12 and 13 in its locked or toggled position is situated just off the line 17, particularly to its right, indicated by 14A in fig. 2. This has the advantage that a stable position of the arms 12 and 13 is obtained.
  • the hinged blocking mechanism 6 can be folded together in the other direction, such that the lock 5 can be turned round the fulcrum 7 and the support 3 is consequently opened.
  • 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 a torsion spring 19, mounted round a shaft 19A on the support 8, and pressing against the arm 12 with a free end, such that the latter is forced against the stop 18.
  • 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 a torsion spring 19, mounted round a shaft 19A on the support 8, and pressing against the arm 12 with a free end, such that the latter is forced against the stop 18.
  • the device preferably also has means which allow to activate the hinged blocking mechanism 6, in order to open the lock 5.
  • These means can in the first place consist of a handle 20 by which the blocking mechanism 6, particularly the arms 12 and 13, can be folded together, such that the lock 5 can be opened manually.
  • the handle 20 preferably makes up part of the above-mentioned arm 13 and is at an angle in relation to the connection line between the fulcrums 14 and 16.
  • the means which allow to activate the hinged blocking mechanism 6 can also consist of an element which can be moved by means of a shaft 1 presented to the device, such that the lock 5 is opened.
  • the above-mentioned element is formed by a protruding part 21 of the arm 13, such that this part 21 is situated above a supporting plane 22, over which the shaft 1 can be rolled to the bearing 3, and whereby the part 21 is situated in the path of the shaft 1.
  • the supporting plane 22 may have a recess 23 or similar, in which a shaft 1 can be placed in waiting position at its ends 4.
  • the bottom side 24 of the locking element in other words, the side which rests on the supporting plane 22, has a rounded form, such that the shaft end 4 can easily pass underneath the locking element 5.
  • the arm 13 preferably has a cam 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.
  • the torsion spring 19 keeps the hinged blocking mechanism 6 in such a position that the fulcrums 14, 15 and 16 are situated in one line , or in a position whereby the middle fulcrum is situated at another place, indicated by 14A.
  • the lock 5 cannot possibly be moved upward at the fulcrum 16, so that the support 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 supporting plane 22. Hereby it first makes contact with the above-mentioned part 21, as shown by the dashed line in fig. 2, such that the blocking mechanism 6 and the lock 5 are opened, such that the shaft 1 can be slid in the supports 3 unhindered.
  • the lock 5 can be opened manually by tilting the handle 20 according to arrow A, such that a situation is created, as shown in fig. 4, whereby the shaft ends 4 can pass freely underneath the lock 5.
  • the fulcrums 7, 14, 15 and 16, as well as the arms 12 and 13 and the lock 5 are constructed such that when the handle 20 is pulled down completely, the arm 13 and the lock 5 are toggled round the fulcrum 16 until the whole comes in contact with a stop 26, for example formed by the edge of the support 8.
  • a stop 26 for example formed by the edge of the support 8.
  • the blocking mechanism 6 remains in a stable deactivated position, as is represented schematically in fig. 5.
  • a pushing mechanism 27 exerts a force F on the part 21 in order to bring the blocking mechanism 6 in its non-blocking position, before the shaft 1 is removed from the supports 3, sliding over the supporting planes 22, by means of suitable movable arms 28 or similar.
  • an adjustable eccentric 29 is preferably mounted in the fulcrum 15, so that the fulcrum 15 can be shifted.
  • the setting of the stop 18 also allows the part 11 of the support 3 to come loose from the shaft end 4, such that the shaft 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 a lever 30.
  • the lock 5 hereby also consists of an arm which can turn round a hinge point 7.
  • the connection between the lever 30 and the lock 5 consists of a hinge clutch 31 which provides a well-defined play such that the lever 30 and the lock 5 act on one another by means of a pin slot clutch.
  • the lever 30 can be turned round a fulcrum 32 which is situated fixed to the frame and is charged by means of a spring 34 or similar at the end 33 which is situated opposite the hinge clutch 31, such that the lock 5 is pressed in its locked position, whereby in this position the fulcrum 32, the shaft 1 and the centre of the hinge clutch 31 are almost in one line 35.
  • the end 33 has a handle 36 and, at its underside, a cam 37, whose aim will become apparent from the description below.
  • a stop 38 is provided against which an element 39, such as an arm for removing the shaft 1, can be presented to move the lever 30 against the force of the spring 34.
  • the lock 5 also has a part 40 which can operate in conjunction with an adjustable stop 41, in order to avoid that the movable part 11 exerts a frictional force on the shaft end 4.
  • the part 40 can also operate in conjunction with a flexibly bendable stop 42, such that when the part 40 is moved past this stop, the lock 5 cannot be moved back by the force of the spring 34.
  • the supporting plane 22 over which the shaft 1 can be supplied is preferably placed horizontally. It is clear that the above-mentioned elements 39 for supplying and removing shafts 1 are provided with suitable driving means to move these horizontally and vertically, and to take up a shaft 1, such as a cloth roll or a warp beam, particularly as described below.
  • Fig. 7 shows the application of a shaft 1 in the support 3.
  • the shaft 1 is pushed forward over the supporting planes 22, situated underneath the shaft ends 4, by exerting a horizontal force on it by means of the above-mentioned elements 39.
  • the shaft ends 4 hereby slide underneath the lever 30 and the lock 5, whereby the latter are pressed aside conveniently.
  • Removing the shaft 1 is done by deblocking the blocking mechanism 6, for example by exerting an upward pressure on the stop 38 by moving the element 39, respectively the elements 39, upward until a position is reached as indicated in fig. 8. Then the shaft 1 can be pulled out of the support 3 by moving the elements 39 to the left, whereby the shaft ends 4, however, keep resting on the supporting planes 22.
  • the lever 30 is pulled down at the end 33 until a position is reached as shown in fig. 9, whereby the lock 5 is opened and is held behind the stop 42. Then the shaft 1 can be slid out of the support 3 over the supporting planes 22.
  • Fig. 11 shows a variant whereby on the blocking mechanism 6, particularly on the above-mentioned arm 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.
  • this movable element 44 may consist of a transport arm in order to remove the shaft 1 from the supports 3, whereby the upper side 45 makes contact with the stop 43 when the transport arm is presented to the shaft 1.
