The specific embodiment
Fig. 1 shows the tufting apparatus 10 that is used to make tufted articles 11.This goods for example are velvet carpets.It comprises the for example weaving back lining materials 12 on smooth plane, as shown in the dotted line among Fig. 1.This back lining materials has pile yarns 13, and it is stamped through back lining materials 12 so that at first form coil 14.Along with process continues, these coils are cut open, so that form open coil and therefore form clipping 15.This is to accomplish through the tufting clamper 16 that is associated with cutting knife 17.A plurality of tufting clampers 16 are arranged on the sinker adjacent to each other, and sinker is given the working motion of tufting clamper 16 expectations.The cutting knife 17 of respective numbers also is arranged on the sinker, and for cutting operation, sinker is carried out the motion to clamper 16.
In order to produce the coil 14 that will choose by clamper 16, promptly be used for punching press pile yarns 13 through back lining materials 12, used tufting needle 18, each said pin makes its oneself pile yarns 13 move through its pinprick.Tufting needle 18 itself has known design with cutting knife 17.Tufting clamper 16 can be inserted into as the tufting clamper of conventional design, yet, improved clamper according to the present invention, so that improve service life, the especially service life of tufting needle 18.
Tufting clamper 16 according to the present invention comprises especially by the clamp body 19 shown in Fig. 2 and Fig. 3.Clamp body 19 is configured to represent flat member and has two flattened side 20,21.They need not to be the plane, yet they can have plane domain.The flattened side 20,21 of adjacent clamper 16 is defined for the leg and the clipping 15 of coil 14 and is used for tufting needle 18 and the narrow slit-shaped passage of cutting knife 17 between them.Especially when relating to intensive suede, these passages are relatively closely.Through limiting, therefore tufting needle 18 contacts clamper 16.Equally, when coil 14 was cut, cutting knife 17 contacted clampers 16 at least.
As shown in Figure 1, the main body 19 of clamper 16 comprises elongated clamping finger 22 and the base portion 24 that extends towards tufting needle 18.Clamping finger 22 can have the grabber 23 away from back lining materials 12 bendings at its free end, and said grabber forms hook.Finger 22 is straight between the grabber 23 of the main body 19 of clamper 16 and base portion 24.As shown in Figure 1, finger 22 is arranged to choose coil 14.For this reason, said finger has straight edge 25 at its downside.This edge is as cutting edge 26, promptly at least one side of clamp body 19.
Cutting edge 26 is arranged on the cutting tip 27, yet and extends to from base portion 24 along the whole length of finger 22 in this exemplary embodiment at least that grabber 23-this not necessarily.Additional blade 28 and cutting tip 27 arranged adjacent, additional blade 28 have the profile identical with cutting tip 27 in this exemplary embodiment, and at the said blade of plane surface 29 place's butts.When cutting tip 27 during in abutting connection with the flattened side 21 of tufting clamper 16 (Fig. 3), another blade 28 does not have step and biasing ground in abutting connection with flattened side 20 (Fig. 2).
Cutting tip 27 for example is connected mutually through glue or scolder at plane surface 29 places with additional blade 28, thereby and form unit 30, this especially can obviously see from Fig. 4.Other joining techniques be can use, for example laser point or laser seam used as edge on surface 29.
Cutting tip 27 has hard material surface 32.If cutting tip 27 is made up of hard material, surface 32 for example can be the surface that is made up of this material so.This material can be hardened steel, hard metal, for example as tungsten carbide, cermet, or also can be pottery.Also can make cutting tip 27, and make hard material surface 32 with second hard material with first hard material.For example, cutting tip 27 can be made up of tungsten carbide, and hard material surface 32 can be constituted or is made up of the layer assembly that comprises various hard materials by titanium nitride, aluminium oxide, other hard materials.
Preferably, additional blade 28 is made up of the other materials that is different from cutting tip 27.Preferably, this is the material with low-friction coefficient.In abutting connection with flattened side 20, blade 28 has and hard material surface 32 visibly different surperficial 34.Especially, in view of with the contacting of tufting needle 18, surface 34 demonstrates low abrasion effect.For example, additional blade 28 can be made up of the material that demonstrates the emergency lubrication characteristic, for example comprise carbon metal structure, comprise the metal structure of tin etc.And surface 34 can be the ceramic surface with low-friction coefficient and minimum roughness height.
Briefly, tufting apparatus 10 operations of describing so far as described below:
During operation, thus remain on a plurality of tufting needles 18 punching press pile yarns 13 on the sinker through back lining materials 12 and form coil.Because the relative motion of said clamper, these coils are grasped by a plurality of tufting clampers 16 that support through sinker, so that coil 14 can be chosen by finger 22, this can obviously see from Fig. 1.During operation cycle, a plurality of cuttves 17 that remain on the sinker bar promote and on the cutting edge 26 of a plurality of tufting clampers 16, they are separated along the direction of the coil of choosing 14, so that form clipping 15.
During this process, cutting knife 17 contact cutting tips 27 and slide along the hard material surface 32 of said blade, wearing and tearing are minimum.
Tufting needle 18 contacts with tufting clamper 16.When doing like this, tufting needle 18 slides along additional blade 28 particularly.For example because hardness and/or smoothness and/or the softness and/or the emergency lubrication characteristic of said blade can make the abrasion effect of blade 28 minimum, and the wearing and tearing of pin are negligible little.Especially prevented the local sharp-pointed of pinprick edge, itself otherwise can cause damaging pile yarns 13.
Many changes of tufting clamper 16 are possible.As from shown in Figure 5, for example, cutting tip 27 can be configured to independent blade with additional blade 28.In this case, groove 31 does not extend through the whole thickness of tufting clamper 16.On the contrary, said groove has the bottom 35 that groove 31 is divided into two independent grooves 36,37. Groove 36,37 can have identical profile or different profiles.They are opened to ipsilateral not.Groove 36 connects boundary's flattened side 21 separately, and groove 37 connects boundary's flattened side 20 separately.And, consider this exemplary embodiment, cutting tip 27 can combine through material with additional blade 28, for example is fastened in the groove 36,37 through glueing joint or welding.
And, as shown in Figure 6, comprise that the assembled unit 30 of two blades 27,28 can be based on the matrix of sharing 38.Said matrix can have thin plate a side or also have the layer 39 of representing hard material surface 32.Hard material surface 32 is not then to have biasing and mode very close to each other in abutting connection with flattened side 21.The surface 34 that is positioned on the another side of tufting clamper 16 preferably is made up of different materials, and it can be applied to matrix 38 with the form of thin layer or plate 40.Especially this plate of side 34 forms or layer 40 produce the slidingsurface that is used for tufting needle 18 then.Every kind of aforementioned interconnection technique can be used for the unit 30 according to Fig. 6 is fastened in the groove 31.Can have side view according to the cutting tip 27 of Fig. 4 or Fig. 6, additional blade 28 and/or unit 30 according to Fig. 7.The periphery towards the wall of groove 31 (36 or 37) of each blade can have gasket member 41.This gasket member for example is knot shape or a rib shape protuberance 42,43, and this protuberance has the corresponding height of thickness at the expectation junction surface between the edge with the circumference that is formed on unit 30 and groove 31.Preferably, this highly is ten/several millimeters.It is set up and for example produces thickness limited hard solder joint, and also is used for split hair mode corresponding blade 27 or units corresponding 30 being positioned in the groove 31.
Fig. 8 shows an alternative embodiment of the invention of being represented by tufting clamper 44 forms.This clamper comprises elongate finger member thing 22.For example grabber 23 can omit.Suppose that cutting tip 27 and additional blade 28 are arranged in the groove 31 as assembled unit.Groove 31 has form fit structure 45 on its top, and when unit 30 was pushed against said form fit structure 45, said structure was fixed on unit 30 in the groove 31.For example, the edge of groove 31 has arc at its top side end.The edge of groove 31 limits blade or unit 30 with hook-shaped mode, thereby fixes said blade with the form of form fit along vertical direction.The edge of groove 31 can 21 be straight from flattened side 20 to flattened side with respect to horizontal direction.Alternatively, form fit structure 45 can have transversely in the direction rounding of tufting clamper 45 or become the shape at angle, so that also with the lateral position of form fit mode fixed cell 30.
In all previous embodiment; Can be applied to unit 30 separately and be applied to cutting tip 27 and additional blade 28 through this method, promptly be applied to embodiment that comprises gasket member 41 and the embodiment that does not use gasket member 41 from the spring force fixed blade of spring member 46.
In order to reduce or in order to prevent wearing and tearing on the tufting clamper 16 and contact point place tufting needle 18, except wear-resisting cutting tip 27, additional blade 28 to be provided also, said additional blade 28 is intended to interact with tufting needle 18.Said additional blade is made up of the material that forms best sliding combination in pairs with tufting needle 18.Preferably, additional blade 28 is soft province's pin blades.Preferably, cutting tip 27 is wearing blades of hard.Two blades 27,28 can be contained in separately in the different groove 36,37, perhaps are contained in together in the groove 31.They can be interconnected or process integratedly.
