Definitions
- the devices for forming the crowd are generally made by means of a frame mechanism comprising hooks which are raised and lowered by claw frames, a selection from a cardboard being made so that the hooks are grasped or not by said claw frames.
- each arch is associated with the first pulley of a lifting beam which comprises a second pulley surrounded by a funicular member whose ends are integral with two hooks which are continuously moved vertically alternately in opposite directions by means of suitable devices such as knives.
- a lifting beam which comprises a second pulley surrounded by a funicular member whose ends are integral with two hooks which are continuously moved vertically alternately in opposite directions by means of suitable devices such as knives.
- the lifting beam that is to say the system with two pulleys, one of which is surrounded by the funicular element ensuring the connection between the two movable hooks, while the other cooperates with the yoke , is subject to parasitic movements.
- the improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of a device for training the crowd in a weaving loom which may include a large number of yarn lifting systems. chain.
- the device according to the invention is essentially characterized in that the elements of each system, that is to say the retaining hooks with their selection device, the movable hooks, and the lifter are arranged threaded between two vertical partitions connected to each other so as to form a compact and autonomous assembly.
- a number of assemblies are assembled side by side so as to constitute a module which can easily be extracted or replaced in the event of an incident in place of any other. because it is preset.
- FIG. 1 Schematically illustrated in FIG. 1 a layer of warp threads 1 placed on a loom and which comes from a beam 2.
- Each warp thread passes through the eyelet 3a of a heddle 3 intended to open the pitch to allow the passage of a pick in order to constitute a fabric which is wound on a spool 4.
- the lower ends of each stringer are connected to the frame by a tension spring 5, while their upper ends are each secured to an arcade 6.
- the arches are raised and lowered by means of a device for forming the crowd referenced 7.
- the device for forming the crowd 7 is in the case of the present invention constituted by a funicular member 8 at each end of which is associated a hook 9.
- the latter comprise a lateral beak cooperating with a knife 10 animated by a movement vertical alternative as is well known.
- the funicular element 9 passes around the first pulley 11 of a spreader 12 whose second pulley 13 is surrounded by an arch 6.
- the end of the latter opposite to that which is connected to the screw 3 is anchored to a fixed point 14 of the machine frame.
- the upper part of the device 7 is provided with retaining hooks produced in the form of flexible blades 15 associated in the known manner with a single electromagnet 16 intended to vary the position of the blades so that the latter are moved towards the center when the electromagnet is excited so that their curved ends 15a can grip one or the other or the two hooks 9.
- the electromagnet 16 is not supplied, so that the hooks 9 rise and fall without being grasped by the curved blades 15 so that the corresponding warp wire remains in its position low.
- Illustrated in fig. 3 the reverse position of the movable hooks which does not change the positioning of the arm and the wire corresponding chain since the lifter remains in a stable position.
- the electromagnet 16 If at the position of the movable hook of fig. 3 the electromagnet 16 is excited, the two blades are attracted so that during the descent of the corresponding knife, the hook considered remains in the high position, so that the blade 10 descends empty. During the rise of the other blade, the lifting beam 12 will be raised and that of the yoke and of the beam considered to arrive at the position of FIG. 4 in which the two movable hooks remain in the high position so that the corresponding warp thread remains raised in the open step position.
- the power to the electromagnet is cut off, so that the two blades move away from its core.
- One of the hooks is gripped by the first knife which arrives at its level and causes it to descend while the other remains attached to the curved blade 15.
- the other knife arrives at the hook which remains at the top, it unhooks it from the curved end 1 5a of the blade 15 so that it returns to the position illustrated in FIG. 2 on which we see the hook associated by its side beak with the knife 10.
- a system will be referred to herein as all of the control elements of an arch, that is to say the electromagnet 16, the two bent elastic blades 15, the two movable hooks 9 with their funicular element 8 as well as the lifter 12.
- each system described above is placed between two dividing partitions 17, connected together at their head 17a and their lower part 17b.
- spacers 17c ensure the spacing of two adjacent dividing partitions allowing the passage of the movable hooks 9. This thus constitutes a compact and autonomous assembly.
- each separating partition 17 is provided with an oblong opening 17d constituting a guide for the lifter 12 which comprises two flanges 12a each engaging in an opening 17d.
- each separating partition 17 is provided with two shoulders 17e intended to rest on two crosspieces 18 of the device 7.
- the lower part 17b of the dividing partitions 17 has a notch 17f allowing it to overlap a third retaining crosspiece 19 or vice versa.
- a number of autonomous assemblies such as that illustrated in FIG. 6 so as to constitute a module 20 comprising, without limitation, for example six to ten assemblies.
- the module supports a plate 21 comprising the supply circuit for the corresponding electromagnets. Said wafer is skewered with respect to complementary sheets carried by devices 7 and which have not been shown in the drawings.
- each module 20 can be removed for maintenance or repair reasons in a simple manner and in a very short time. It goes without saying that the replacement of a module is carried out under the same conditions by making its retaining means 17e, 17f cooperate with the crosspieces 18, 19.
