Description
Technical field
The present invention relates to a kind of top comb that is used for combing machine, it has the top comb support, and said top comb support has the fixed part that is connected on the supporting plate, and pin bar or top comb card clothing are fixed on the said supporting plate.
Background technology
In combing process, the alternation dynamic loading is born in the top comb of combing machine, and this alternation dynamic loading partly shows in the strain of top comb, especially on its longitudinal direction.This exerts an influence to the fixing point of top comb in the combing machine conversely.That is to say that the top comb relatively resilient bias that laterally produces of its longitudinal direction causes relatively moving between the fixed part of hard-wired fixture (for example geometrical clamp) and top comb.Therefore fixed part is worn in this zone.Normally, according to the number of combing head, on combing machine, use 8 top combs.
In order to reduce wearing and tearing, proposed among DE-102 52 098 A1 between top comb and top comb fixed mount, to use wear-resistant layer.Therefore, although the wearing and tearing in should the zone can reduce, dynamic loading or skew are still as usual.That is to say that the reason of wearing and tearing is not eliminated thus.
In order to obtain the best carding effect of top comb, the distance between top comb card clothing or pin bar and the following detaching roller (following detaching roller) need keep shortly as far as possible.In installation process, the location of top comb also must consider because dynamic loading and the skew that takes place transverse to the longitudinal direction of top comb.That is to say that the minimum range of choosing between top comb and the detaching roller must be greater than side-play amount, when avoiding top comb to be positioned at its combing position and detaching roller collide.Because the skew of above-mentioned top comb is looked along the fibroreticulate width of treating separation (take off), has also obtained different combing situations, this is because this skew reduces on the outer extreme direction of top comb.Therefore, because skew, the distance between top comb and the detaching roller is the shortest in zone line, and on direction outward, increases.This possibly make the different carding effect of generation on the length of top comb.
Then, can imagine the appearance and size that increases top comb for the skew that reduces top comb.But this can cause disadvantageous consequence, i.e. the weight of top comb increases under certain situation significantly.Because the higher combing cycle (KS/min), this will cause the increase that energy consumes subsequently, and will on the Support Position of pliers assembly, arrange extra load.
Summary of the invention
Therefore, the top comb that the objective of the invention is to avoid above-mentioned shortcoming and propose to have the bending strength of increase, thus relatively moving between fixed part and its securing member of top comb minimized.Simultaneously, take every caution against error changes with the size of guaranteeing top comb only smallly, and guarantees to consider the narrow geometry installation dimension of the top comb between pliers assembly and the detaching roller.
Above-mentioned purpose is achieved in that the present invention proposes at least one additional reinforcement is installed on supporting plate, be used to increase the bending strength of top comb support on its longitudinal direction.
Word " longitudinal direction " is meant the length direction of top comb, the through-flow direction horizontal expansion of fibrous material relatively on the installation site of said top comb in combing machine.
Because the setting that is proposed, the quality of top comb increases smallly.Reinforcement can be installed in such zone, although mounting condition is very narrow, reinforcement can not constitute any obstruction yet in this zone.Therefore, preferably, look from the installation site of top comb, reinforcement is installed on the relative side of the detaching roller of supporting plate up and down face.Through-flow direction along fibrous material is looked, and this side is corresponding with the front side of supporting plate.
Further preferably, look along the longitudinal direction of top comb support, reinforcement extends to its two ends from the centre of top comb support, and leaves end one segment distance of top comb support.Therefore, like present knowledge, the securing member that is used for fixing top comb can be used in each residue free space between each end of end and top comb support of reinforcement.
In addition, the present invention also proposes reinforcement is connected with supporting plate with fixed part.This provides stable with compact especially form, has also realized the remarkable increase transverse to the bending strength of the longitudinal direction of top comb support thus extraly.And, this thus can reinforcement be processed into hollow profile with fixed part and supporting plate.This provides the setting of the top comb support with light weight structure, has also increased bending strength simultaneously.As stated, it has realized the increase of top comb support transverse to the bending strength of its longitudinal length, and this helps in separation or combing operation, keeping the invariant position on the top of top comb card clothing equally.
In order to be fit to the geometrical condition in the detaching roller zone, the present invention proposes hollow profile and has the transverse cross-sectional area of looking and reducing along the top orientation of pin bar along cross section.
For the introducing optimization that production cost is minimized and exert all one's strength, the present invention proposes by fixed part, and the top comb support monoblock that supporting plate and reinforcement form is made.
The present invention proposes the top comb support and is made of plastics, and makes its weight saving, and possibly improve the combing cycle, and increases bending strength.
Through correspondingly being designed to the reinforcement of hollow material (hollow profile), the top comb support also is fit to processed by extrudate (extruded profile).
In this case, for weight reduction, extrudate can by nonmetallic materials for example aluminium alloy constitute.
In addition, the present invention's proportion of also proposing reinforcement is lower than the proportion of fixed part and supporting plate.Therefore it possibly increase the bending strength of top comb support, and the weight of top comb support only increases slightly.
Particularly in use the top comb support such reinforcement being installed subsequently, if these reinforcements can be connected to supporting plate or are connected on the supporting plate and fixed part of top comb support through adhesive, this is very favorable.
The object of the invention can also be provided with realization through another kind, and wherein supporting plate is being provided with protuberance in the subregion at its longitudinal direction aspect its transverse cross-sectional area at least, and these protuberances increase the bending strength of supporting plate on its longitudinal direction.That is to say, the reinforcement that is used to increase bending strength directly and supporting plate be integral.
Other advantage of the present invention will describe in further detail and explain through following illustrative examples.

The specific embodiment
Fig. 1 shows the cross section of the top comb support 2 of the top comb that is used for the combing machine (not shown) 1 of design according to the present invention.This top comb support 2 is formed by fixed part 4, and gripper shoe 5 is fixed on this fixed part 4.The shape of cross section of fixed part 4 is the opening section bar (openprofile) with arcuate outer surface.
In this case, fixed part 4 and supporting plate 5 can one-body molded (for example, being processed by plastics or extruding aluminium alloy).In order to increase the especially bending strength on its longitudinal direction L of top comb support 2; According to the present invention; Reinforcement 11 is fixed in the join domain 9 of fixed part 2 and supporting plate 5, and from as finding out Fig. 2, this reinforcement 11 extends on the almost whole length of top comb support 2.Can expect that also a plurality of reinforcements are arranged and installed to space one segment distance on the whole length of top comb support 2.Yet, as shown in Figure 2, when reinforcement 11 is designed to consecutive hours, can obtain to increase the maximum efficiency of bending strength.As can be seen from Figure 2, reinforcement 11 ends at branch and takes leave of the outward flange R 1 of top comb support 2, R2 one segment distance a place.This distance is used for top comb support 2 is mounted and fixed on top comb fixed mount 17 for the free space in the zone of a, as being schematically shown among Fig. 3.
Triangular cross section reduces downwards gradually, thereby guarantees the pressure cylinder collision that reinforcement 11 can not be provided with the installation site of next-door neighbour's top comb 1 of following pair of separated roller.Detaching roller can be from for example recognizing the disclosed patent EP-354456A2 with respect to the geometrical arrangements in the top comb.This is formerly announced also schematically to have described and how top comb fixed mount 17 is fixed on the top pecten on the following pincers that are installed in the pliers assembly.
In the lower area of supporting plate 5, top comb card clothing 7 is fixing with grip block 15 through a plurality of screws 14.Number according to screw 14 forms a plurality of screwed holes 16 on supporting plate 15.Card clothing 7 is clamped on the supporting plate 5 through screw 14 and grip block 15 firmly.
The top comb card clothing 7 of top comb 1 can be the form of the pin bar that is arranged in a row each other, or the form of the sheet metal of punching press that is arranged in a row each other or mold pressing (embossed), or other form.But this is unimportant to explaining the present invention.
Fig. 2 a is the viewgraph of cross-section along A-A, and its skew b that schematically shows the supporting plate 5 of top comb support 2 is how owing to the power F that on through-flow direction D, produces forms.Such as knowledge, next drafted in lock out operation by the fiber edge (fiber fringe) that circular comb combs out, pass the top comb card clothing 7 of top comb 1 along through-flow direction D through detaching roller.The power F that produces under this situation will cause the skew b of supporting plate 5, particularly in the zone line of top comb 2.This is a resilient bias, and it is at power F disappearance after vibration return.That is to say that under the situation in combing cycle of for example 500KS/min, this operation per minute takes place 500 times.Elastic vibration is passed in the FX a of top comb 1 along the longitudinal direction L of top comb support 2.This has produced the periodic relative motion of high-frequency (high number) between fixed part 4 and each securing member, top comb 1 is fixed on its position on combing machine through fixed part 4 and each securing member.Fig. 3 (looking along the Y direction) shows one of them securing member, and this securing member is the form of geometrical clamp 21, and it can be installed on the top comb fixed mount 17 around axle 22 pivotallies.Geometrical clamp 21 designs at its free end in such a way, makes that it sets a latched position when geometrical clamp 21 is bonded on the arc outline of fixed part 4.In addition, the effect of this geometrical clamp can be recognized from the illustrative examples the DE-10252098 A1.
Dotted line 21 ' among Fig. 3 shows the geometrical clamp 21 that is positioned at unlocked position, and wherein top comb support 2 can upwards take out from the slit 19 in the vertical socket 18 of top comb fixed mount 17.For each top comb, two this top comb fixed mounts 17 are fixed on the pliers assembly, also not shown among the figure.Like what in introduction, described, particularly, fixed part 4 is worn in the zone of its securing member 21 owing to said relative motion.According to the present invention, through reinforcement is installed, skew b reduces significantly, and has therefore also eliminated the risk of wearing and tearing in the zone of fixed position.Through skew is reduced to minimum, it has guaranteed that also how much combing situations remain unchanged basically on the whole length of top comb 1.
Fig. 4 shows another exemplary embodiment, and wherein, according to the setting shown in Fig. 1, top comb support 2 comprises fixed part fixed thereon 4 and supporting plate 5 equally.The installation of top comb card clothing 7 is also corresponding with the illustrative examples according to Fig. 1.In the present embodiment, reinforcement 12 is installed in the join domain 9 between fixed part 4 and the supporting plate 5, and has the for example cross section of rectangle.But, also can expect other shape of cross section.Reinforcement 12 is connected on fixed part 4 and the supporting plate 5 through adhesive layer 24.Also can expect reinforcement 12 being connected on supporting plate 5 or the fixed part 4 firmly through other fixing means (for example through weld, rivet, be threaded etc.).The installation method of the reinforcement 12 shown in Fig. 4 is specially adapted in textile mills, install subsequently in the already used top comb reinforcement.
Preferably, reinforcement 12 can be formed by nonmetallic materials (for example plastics), therefore through additional reinforcement is installed the removable amount of top comb is only increased slightly.
Fig. 5 shows another illustrative examples of the present invention, and supporting plate 5 itself is provided with the protuberance P1 that extends along the longitudinal direction L of top comb support 2.Fig. 5 a shows among Fig. 5 the view along the Z direction.As can be seen from the figure, protuberance P1 is from the edge R1 one segment distance a of top comb support 2.On the opposite side (not shown), protuberance P1 ends at isolated edge R2 one segment distance a place equally.Like what in illustrative examples shown in Figure 2, described, the free space that has apart from a is used for top comb support 2 is mounted and fixed on top comb fixed mount 17 (Fig. 3).Protuberance P1 can or use other known manufacturing approach processing through deep draw, mold pressing.Supporting plate 5 can be processed in same operation with protuberance P1, and this depends on material.In example shown in Figure 5, shown in illustrated property, supporting plate 5 is connected with fixed part 4 through weld seam.Also can use the connected mode of other types.Fixed head 4 equally can be one-body molded with supporting plate 5.
Fig. 6 and appended side view along the K direction (Fig. 6 b) have shown another illustrative examples, wherein triangle protuberance P2 fully and supporting plate 5a in aggregates.In addition, fixed part 4a also is connected to supporting plate 5a firmly.That is to say that in the example of Fig. 6, supporting plate 5a and fixed part 4a with protuberance P2 are one-body molded.On the one hand, this provides advantage for the processing of top comb support 2, and on the other hand, the power of generation optimally is introduced on the parts of top comb support.In the present embodiment, the reinforcement protuberance that is used to increase bending strength ends at respectively from each edge R1 and R2 one segment distance a place.For the top comb support of processing by extrudate among Fig. 62, be to remove the protuberance P2 in this free space through corresponding processing by the free space of a in order to obtain distance.
Various distortion about the installation of additional reinforcement are also unlisted here, but these distortion also possibly fall in the scope of the present invention.
