Description

Combing machine

The present invention relates to a kind of combing machine with a plurality of combings position (combing station), wherein, the ribbon that forms in each single combing position supplies to the drafter unit and becomes ribbon by the fiber web of drafter unit output via fiber web pack (gathering) mechanism pack through director element, this ribbon is output on driven conveying mechanism, this conveying mechanism is transferred to outgoing position with this ribbon, and ribbon is diverted and vertically exports to the strip stocking mechanism downwards at this outgoing position place.

By more known combing machines in the reality, wherein, the ribbon of locating to form at each single combing head (combing position) is placed on the output table side by side and is transferred to subsequently drafter unit.This drafter unit generally roughly is positioned at the top of output table, only also needs the inclined-plane of the rising of a weak point thus between the end of drafter unit and output table, so that the input roller that ribbon is transferred to the drafter unit from output table is right.Drafted mechanism unit drawing-off be converged into ribbon and output to driven conveyer belt subsequently through fiber web pack mechanism (for example fiber web funnel) with fiber web output.A kind of such device for example can be known from EP-640705A1.By conveyer belt, next ribbon is transported on the outgoing position of strip stocking mechanism top, and the pressure roller that vertically outputs to downwards subsequently of ribbon is right from here.Pressure roller is to transferring to ribbon funnel wheel subsequently, through funnel wheel is in place ribbon bar tube below it with tubular shape in.Extremely be provided with the pressure roller in the branchpoint place of driven conveyer belt at ribbon, the main and conveyer belt formation bite of this pressure roller, ribbon is supported on the conveyer belt reliably and is pulled away thus.

In DE-19640855A1, be shown specifically a this branchpoint to conveyer belt.Wherein, from the fiber web guider of fiber web during feeding guide pipe that the delivery roller of drafter unit is exported, assembled.In order to assist the conveying of fibrous material in guide pipe inside, be equipped with at the guide pipe place and be blown into nozzle (injector).Fibrous material arrives funnel through guide pipe, and fibrous material arrives at pressure roller and conveyer belt by this funnel, or is used for the bite between the roller of turning to of this conveyer belt.Describe in the embodiment that illustrates of the open source literature of quoting, be used for the steering front wheel of conveyer belt and the pressure roller installed in this zone should be a pressure roller, this pressure roller forms clamping gap.But main clamping action is to form at the pressure roller with between by the conveyer belt of deflection a little herein, and the ribbon that is conducted through the clamping gap is thus pushed flatly and compressed a little.Ribbon can be offset out to the side in the zone in clamping gap, can not realize can not realizing in other words solid significantly (fixed) of ribbon the raising of the adhesive force of ribbon thus.That is to say, utilize the device shown in this can not realize solid targetedly to ribbon.The shortcoming of this embodiment also is from the right outgoing position of the delivery roller of drafter unit up to the transfer to the arc of the outgoing position of subsequently conveyer belt in addition.Each turning point that is used for ribbon all influences the structure of fiber strip owing to the friction that exists, this also can produce adverse influence to the quality of ribbon.

In order to aid in the guiding of ribbon to the zone of the outgoing position of strip stocking mechanism, additionally be provided with guide plate in the illustrated embodiment.

The various embodiment of conveyer belt have been shown in disclosed JP-OS-9-119026, and ribbon is transferred to strip stocking mechanism subsequently from the drafter unit whereby.For solve under the high transporting velocity in the problem that especially produces on the conveyer belt to the zone of the outgoing position of strip stocking mechanism (because centrifugal force), suggestion herein, correspondingly directed at the pressure roller quilt of installing there, or design feeding funnel subsequently.It is tiltedly directed to advise in addition nearby conveyer belt correspondingly being dipped down before outgoing position.By these measures, under the transporting velocity of a restriction, the transfer that ribbon takes feeding funnel subsequently to from conveying can be implemented on no problem ground.Under the further raising of combing cycle-index and the situation in the raising of the transporting velocity on the conveyer belt that is associated therewith, these measures no longer are enough.That is to say that the transporting velocity on conveyer belt is high more, so owing to act on centrifugal force on the ribbon, just big more in the ribbon of the output danger that is offset out annularly downwards to the zone of the outgoing position of strip stocking mechanism.Produce additional tensile force thus in this zone on ribbon, it finally can cause ribbon to fracture.

More known embodiment in the other open source literature by DE19923576A1 and JP-4-263623, wherein, the drafter unit directly is arranged in strip stocking mechanism top.Obtain advantage thus, promptly the fibrous material of being exported by the drafter unit can be output to strip stocking mechanism place subsequently on short relatively stroke.But on the other hand, from the ribbon of each single combing position output, it has relatively low adhesive force, must carry up to the drafter unit on long conveying highway section.This contains the danger that ribbon fractures on the conveying highway section of this length on the one hand and requires special transport on the other hand.In addition in such an embodiment, the drafter unit of the more difficult arrangements of operations of operating personnel above the strip stocking mechanism.In addition, need to install an additional operating platform.

A kind of embodiment based on combing machine, as it for example shown in the EP640705A1, wherein, after following the drafter unit, the conveying mechanism that will be used for the transfer fiber bar places a position of strip stocking mechanism top, the present invention offers the challenge, and promptly improves known embodiment and avoids its shortcoming, even so that also can work under the higher transporting velocity of the ribbon that is used for being exported by the drafter unit.

In order to solve this task, suggestion is provided with the pressure roller that is connected with drive unit between fiber web pack mechanism and conveying mechanism right, wherein, the guiding mechanism of side is set in the zone of the right bite of pressure roller, and it is used for by the ribbon by the bite guiding.

Because being conducted through, the guiding mechanism that is provided with the side in the zone of the right bite of pressure roller can not be offset out from the side during the ribbon of bite is being compacted (fixed).On the entire cross section of ribbon, form the solid of this ribbon thus and cause the raising of the adhesive force of ribbon thus.Because the adhesive force of this raising, the danger that fractures at conveying mechanism (conveyer belt) ribbon to the zone of the outgoing position of subsequently strip stocking mechanism is lowered or is avoided.Also can move at conveying mechanism thus, and fractureing of strip can not taken place in the zone of the branchpoint of key with higher transporting velocity.In addition, by solid ribbon in the clamping gap of pressure roller, the danger that the edge fiber looses from ribbon during carrying on conveyer belt is lowered.

To the further solid of ribbon and improve adhesive force thus and can so realize, promptly the right pressure roller of pressure roller is provided with forming structure on its periphery.By this forming structure, especially the zone of edge fiber is by solid.

In order will accurately to transfer to the right bite of pressure roller from the ribbon of fiber web pack mechanism output, suggestion is provided with the feeding funnel between right bite of pressure roller and fiber web pack mechanism.

Suggestion in addition, fiber web pack mechanism is around pivotal axis, at the throughput direction of ribbon transversely, supporting pivotly in a vertical plane.Fiber web pack mechanism can be transferred to the inoperative position from the operating position thus, so that for example can implement maintenance or cleaning.

If, can use the pivoting action of fiber web pack mechanism so for monitoring purposes for fiber web pack mechanism disposes the sensor that is used to monitor its position.That is to say that by the accumulation of fibrous material in the zone of fiber web pack mechanism, this fiber web pack mechanism is pivoted on the inoperative position from its run location owing to gathering power, this discerns by sensor.Sensor sends signal to control module then, triggers relative measures (for example turn-offing combing machine) then by this control module.

For fiber web pack mechanism is remained on the run location reliably, magnet can be installed at the frame place, this magnet remains on magnet surface originally or remain on the corresponding stop surface that sets by its magnetic force on one's body with fiber web pack mechanism.

Advantageously suggestion in addition, the first right pressure roller of pressure roller is rotatably supported in the frame and is connected with drive unit and second pressure roller is rotatably supported in the pivot rods place, and this pivot rods is arranged pivotly and loaded with pressure mechanism under a spacing with pivotal axis around the pivotal axis that is installed in the frame place.

As pressure mechanism, for example can use the bellows cylinder barrel that is connected with pressure source in the case, it be supported on the frame and pivot rods on.

Suggestion in addition, pivot rods is provided with opposed dividing plate under a spacing mutually, rotatably support second pressure roller between them, wherein, dividing plate protrudes in the external diameter of second pressure roller and forms the guiding mechanism of the side of the ribbon by bite guiding thus in the zone of the right bite of pressure roller.In the case, the parallel distance between relative mutually dividing plate is so to select, and promptly this spacing is only less times greater than the width of pressure roller in the zone of its excircle.That is to say that the corresponding end face of pressure roller can be between 0.05mm and 0.8mm to the spacing of the mutual facing surfaces of corresponding dividing plate.Preferably this spacing is 0.1mm.

Dividing plate is used for rotatably support second pressure roller on the one hand and is used on the other hand at the ribbon of side guiding by the guiding of clamping gap thus.First (descending) pressure roller have with second (on) width that pressure roller is identical.Vertically see, because the accurately mutual upper and lower settings of first and second pressure rollers, therefore have 0.05-0.8mm between the mutual interior surface opposing of the end face (second pressure roller is too) of first pressure roller and the dividing plate that also partly hides first pressure roller, or the spacing of best 0.1mm.

In order on vertical position, to guide ribbon at the right bite of pressure roller with to the zone between the outgoing position of subsequently conveying mechanism, suggestion in addition, dividing plate is connected with a transversal web, and this transversal web is arranged in the zone between right bite of pressure roller and the conveying mechanism subsequently.

Advise a kind of embodiment in addition, wherein, fix the dividing plate that extends under two spacings of being separated by mutually in the zone of the outgoing position of fiber web pack mechanism, right second pressure roller of rotatably support pressure roller and first pressure roller that is connected with drive unit are rotatably supported in the frame and the pivotal axis of dividing plate and fiber web pack mechanism is separated by and is loaded with pressure mechanism under the spacing between it.Fiber web pack mechanism can be pivoted to off-position with second pressure roller of rotatably support between dividing plate from the operating position thus, so that for example can implement maintenance work.

Advantageously, dividing plate protrudes in the external diameter of second pressure roller and forms by the guiding mechanism of the side of the ribbon that guides by bite simultaneously thus in the zone of the right bite of pressure roller.Herein, the spacing between the mutual facing surfaces of the end face of second pressure roller and dividing plate also remains on the minimum dimension (0.05-0.8mm), prevents thus in the clamping gap between pressure roller that ribbon is offset out from the side during the compression (compacting).

In order under high transporting velocity, also to supply to outgoing position reliably from the ribbon of clamping gap output to subsequently conveyer belt (conveyer belt), suggestion in addition, dividing plate the right bite of pressure roller and to the zone between the outgoing position of conveying mechanism the side along the transporting flat of ribbon extend.

Suggestion in addition, the drafter unit is to the outgoing position of fiber web pack mechanism, the bite that pressure roller is right and roughly be arranged in a plane to the outgoing position of conveying mechanism.Avoid some may influence the turning point of ribbon quality unfriendly thus.
