Technical field
The present invention relates to a kind of reinforced embedded member of the suction channel for fiber accumulation device in weaving loom, wherein reinforced embedded member has retention mechanism and the dismounting mouth for easily reinforced embedded member being removed from suction channel for being fixed in suction channel.
Background technology
Fiber accumulation device is arranged in the downstream of drafter, and for pneumatically compacting, leaves the fiber strip of drafter.Pneumatic compacting is characterised in that, fiber strip under the state of not yet twisting with substantially in compacting zone the fiber of placement parallel to each other lean against in ventilative transport element and transport, and in compacting zone, produce one through the air stream of transport element, described air stream is determined compaction according to its width and/or direction, and fiber is located transverse to transporting direction, thereby make fiber strip bunchy or be compacted.In the fiber strip of like this compacting, for twisting configuration, in fact no longer there will be spinning triangle, therefore formed yarn become more evenly, more anti-fracture and seldom fluffing.
DE 102005027189A1 discloses the reinforced embedded member that starts described type herein.Known reinforced embedded member has as the fixed protuberance of retention mechanism and the clip of mating reaction with it.Reinforced embedded member can be arranged in a groove shape vacancy of suction channel.For simplifying reinforced embedded member from the dismounting of suction channel, establish removal hole.Removal hole be designed to can with the instrument mating reaction of screwdriver shape or bottle-opener shape, to reinforced embedded member is pulled out from the groove shape vacancy of suction channel.
In a kind of use in enormous quantities reinforced embedded member in actual applications, removal hole is designed to extend until form the bottom surface of contact-making surface in suction channel from being configured for the end face of the sliding surface of transport tape, through whole thickness.
When fiber accumulation device is worked, may on suction channel, gather some for example form be the dirt of fleeces and/or dust.So suction channel will clean conventionally every now and then.At this, the suction channel taking off from weaving loom obtains blowing brush with pressed gas, so dirt is removed.In known reinforced embedded member, when reinforced embedded member is hit by pressed gas bundle, it can surprisingly be thrown away suction channel.
Summary of the invention
Technical problem to be solved by this invention is, creates a kind of reinforced embedded member of improvement, and it can not come off from suction channel unintentionally.
This technical problem solves thus, and removal hole has lid.
Surprisingly, already showed, when clean suction channel, when blowing brush suction channel with pressed gas and remove dirt, lid can prevent that reinforced embedded member from unexpectedly being come off and throwing away from the groove shape vacancy of suction channel.Probably produce thus positive effect, lid prevents pressure air by removal hole until arrive the bottom of groove shape vacancy and set up a superpressure between the basal plane of groove shape vacancy and the bottom surface of reinforced embedded member, and this superpressure then can put forward reinforced embedded member from groove shape vacancy.
By lid, can make the retention mechanism that is designed to clip there is enough confining forces, to it is fixed in suction channel firmly in the useful life of reinforced embedded member.Structure space space situation based on limited, cannot strengthen the confining force of clip.
If reinforced embedded member finally on its sliding surface because the conveyer belt sliding on this sliding surface is all the time worn and must be replaced, so just on removal hole, place extracting tool.In the time of in extracting tool is inserted to removal hole, cover penetrates.Then can completely extracting tool be inserted in removal hole, and reinforced embedded member can pull out from the groove shape vacancy of suction channel.And then brand-new reinforced embedded member is inserted in groove shape vacancy.For inserting reinforced embedded member, only need it to be pressed into groove shape vacancy, and kayser is in the recess of undercut.
The advantage of transparent lid is, it has formed the closure member for removal hole, but can not hinder the dismounting of being undertaken by extracting tool.Lid prevents removal hole lower opening wide in working order.In addition, lid also prevents that removal hole from being stopped up by dirt and hinders inserting of extracting tool because of pollutant.
In another kind of design of the present invention, lid has the shape of the thin-walled in sealing disassembly hole.Cover this preferably with reinforced embedded member moulding integratedly.Reinforced embedded member is preferably made as die casting.The thin-walled in sealing disassembly hole can just can be produced in the region at removal hole without extra producing cost at this.The thickness of thin-walled is about 0.05mm to 0.5mm.Conventionally several 1/10th millimeters just enough.Thin like this wall can unhinderedly insert extracting tool, thereby takes out reinforced embedded member.
Extracting tool preferably have T shape substantially for engaging-in end regions in removal hole.Removal hole, with regard to its structure, preferably matches with the extracting tool of this shape of T substantially.
In another kind of design of the present invention, stipulate, lid keeps at a certain distance away with the sliding surface of reinforced embedded member.At this, the thin-walled in sealing disassembly hole is not positioned to flush with sliding surface.Lid makes in sliding surface, there is obvious visible depression to the distance of sliding surface, so in int lid, the identification that occupies a good place of removal hole.Therefore,, for changing reinforced embedded member, can pick out well and where settle extracting tool.The distance of lid and sliding surface is in the magnitude of a plurality of 1/10th millimeters.Spacing be preferably chosen as can guarantee good can identification, but still there will not be dirt deposition.

The specific embodiment
The fiber accumulation device 1 of the fiber strip 2 being comprised of staple fibre for compacting has been shown in Fig. 1 and Fig. 2, and it is arranged on the only downstream of the drafter 3 shown in part of weaving loom.The weaving loom that can be for example spinning machine, especially ring spinner has a plurality of drafters that are arranged side by side 3 conventionally at this.
Drafter 3 about designing in known mode own, only shows delivery roller to 4 and arranges that preceding divider tape is to 5,6.
Delivery roller comprises driven bottom roll 7 to 4, and it can be designed to continuous lower roll machine is longitudinal, and each drafted fiber strip 2 is equipped with a calender roller 8.Bottom roll 7 and calender roller 8 form an output jaw line 9 mutually, and it stops the draw zone of drafter 3.
Fiber strip or optional rove are fed to drafter 3 along direction of transfer A, and make it with known manner, to be drawing to desired precision in drafter 3 always.
The delivery roller that follows drafter 3 closely to 4 be compacting zone 11, in this region by drawing-off but still without pneumatically boundling or the compacting of fiber strip 2 of twisting.Fiber accumulation device 1 for this comprises fiber strip 2 transportations by the ventilative conveyer belt 12 of compacting zone 11.Conveyer belt 12 is advantageously designed to the flimsy material band of the fine mesh made with polyamide yarn.
The end of the exit side of compacting zone 11 is limited by a jaw line 13, and jaw line 13 is also used as twisting locking device (Drallsperre) simultaneously, so the fiber strip in compacting zone 11 2 is still untwisted.Then in the downstream of supplying with jaw line 13, form yarn 14, it flows to unshowned twisting mechanism along direction of the supply B, for example, encircle ingot or air nozzle, and twists at this.
In addition, fiber accumulation device 1 also comprises a suction channel 15, and it preferably consists of the hollow profile under negative pressure, and this hollow profile is with the matrix 23 of tubulose.Suction channel 15 advantageously extends on the width of a plurality of drafters that are arranged side by side 3, and is connected on unshowned negative pressure source via negative pressure joint 16.
The outline that faces conveyer belt 12 of suction channel 15 is designed to sliding surface 17, and it guides conveyer belt 12 in this region.Substantially the suction socket 18 extending along transporting direction A is arranged in sliding surface 17, and this suction socket betransported is with 12 coverings, and extends until nestle up supply jaw line 13.As shown in Figure 2, the relative transporting direction A of suction socket 18 arranges slightly obliquely.The type that depends on fiber strip 2 to be processed, suction socket can be also the suction socket of other shape.
In order to realize twisting on jaw line 13 and to stop supplying with, establish one and clamp roller 19, it drives conveyer belt 12, and with certain pressing force by conveyer belt 12 and fiber strip 2 is pressed to sliding surface 17 simultaneously.Clamping roller 19 itself is obtained and drives 4 calender roller 8 from delivery roller by gear 20.Gear 20 is designed to idler gear, the gear on it and calender roller 8 and clamp roller 19 mating reactions.
Owing to clamping roller 19, press to sliding surface 17, so produced certain wearing and tearing on sliding surface 17 in the region of supplying with jaw line 13.Because according to previous experiences, wearing and tearing are confined to supply with in the region of jaw line 13 substantially, so advantageously, arrange there a reinforced embedded member 21.Reinforced embedded member 21 inserts in the groove shape vacancy 22 in the tubular matrix of suction channel 15 below supplying with jaw line 13.Reinforced embedded member 21 should be wear-resisting, simultaneously again should be enough level and smooth, thereby the suffered resistance of the conveyer belt 12 sliding on suction channel 15 is just little.Therefore reinforced embedded member 21 is preferably made by plastic material.Reinforced embedded member 21 relative narrower on transporting direction, it surpasses the width of conveyer belt 12 worthily transverse to transporting direction A.Reinforced embedded member 21 is comprised of longitudinal bodies, this longitudinal bodies with its longitudinal axis transverse to transporting direction A arrange.
Reinforced embedded member 21 contains removal hole 24, and removal hole 24 is arranged in the region outside conveyer belt 12, thereby jaw line 13 is without prejudice.Removal hole 24 is designed to match with the extracting tool of T shape substantially.Reinforced embedded member 21, when its wearing and tearing and necessary replacing, can pull out together with extracting tool from groove shape vacancy 22.
In Fig. 3 and Fig. 4, amplify and show reinforced embedded member 21.Reinforced embedded member 21 is placed in groove shape vacancy 22, and by its sliding surface 25, has lengthened the sliding surface 17 of suction channel 15.Sliding surface 25 forms the end face of reinforced embedded member 21.The bottom surface of reinforced embedded member 21 is by forming with the opposed contact-making surface of sliding surface 25, and reinforced embedded member 21 leans against on the basal plane of groove shape vacancy 22 with this contact-making surface.Reinforced embedded member 21 have with groove shape vacancy 22 in the retention mechanism 27 of undercut recess mating reaction.As shown in Figure 4, reinforced embedded member has the retention mechanism 27 that form is the form fit of fixed protuberance 29 on an end.Reinforced embedded member 21 has a plurality of clips 30 as retention mechanism 27 on its another end.On the same end of reinforced embedded member 21, clip 30 is arranged as removal hole 24.In unshowned design, also can advantageously sliding surface 25 be designed to protruding spherical.Therefore sliding surface 25 can mate with the bend of sliding surface 17.
The thickness of reinforced embedded member 21 is consistent with the degree of depth of groove shape vacancy 22, and therefore, after inserting suction channel 15, the end face 25 of reinforced embedded member 21 flushes ground substantially with sliding surface 17 closed.
In order to work as reinforced embedded member 21, may wear to while finishing its service life and again easily it is taken out from groove shape vacancy 22, removal hole 24 is set.
By the present invention regulation, removal hole 24 has and covers 31.In Fig. 3, can be clear that and cover 31.Lid 31 thin-walleds by sealing disassembly hole 24 form.This wall preferably has the thickness that is about 0.2mm.Lid 31 is penetrated when extracting tool 32 is inserted into removal hole 24.Because the thickness of lid 31 is very little, so it does not form any resistance of being worth mentioning to extracting tool 32.Yet cover 31 huge advantage that have, be, removal hole 24 is closed in the useful life of reinforced embedded member 21.Can prevent that thus reinforced embedded member 21 from throwing away in the cleaning course of with pressure air beam, the dust adhering to and fleeces being cleared out of to suction channel from groove shape vacancy 22.When removal hole 24 does not seal, the confining force of clip 30 cannot stop the pressure of setting up on reinforced embedded member 21 bottom surfaces 26 of the pressure air beam that points to removal hole 24 that reinforced embedded member 21 is extruded from groove shape vacancy 22.Lid 31 destroyed fact when by extracting tool 32 dismounting reinforced embedded member 21 can not brought defect, because reinforced embedded member 21 only can take out in its wearing and tearing and no longer can continue to use time from suction channel 15.
As shown in Figure 3, lid 31 preferably and reinforced embedded member 21 be shaped integratedly.Therefore, using reinforced embedded member 21 when die casting is made, the manufacture of lid 31 means there is more cost again.
As shown in the figure, advantageously, lid 31 keeps at a certain distance away with the sliding surface 25 of reinforced embedded member 21.When damaging, lid can not identify well removal hole thus, because be shown with slight depression in the region of lid 31.Where can identify without doubt thus extracting tool 32 is placed on.Spacing between lid 31 and sliding surface 25 is preferably about 0.5mm.Can guarantee thus to place well extracting tool, prevent from that dirt from accumulating in to cover on 31 simultaneously.
Removal hole 24 be designed to can with extracting tool 31 mating reactions of T shape substantially.For this reason, removal hole 24 is designed to ellipse in the region with end face 25 adjacency.It is designed to substantially rounded in the region with bottom surface 26 adjacency, and wherein diameter is consistent with the full-size of elliptical region.T shape extracting tool 32 can pass according to the form of key the elliptical region of removal hole 24, then half-twist.Then can easily reinforced embedded member 21 be pulled out from groove shape vacancy 22.
