Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an elongated carding plate for a cart for carding textile materials, the carding plate being immovably mounted on the cart. , cooperating with the clothing of the cylinder of cart 0, and comprising a rod-shaped rigid carrier, #1 with respect to the axis of rotation of the cylinder on the side of the carrier cooperating with the clothing of the cylinder of the carrier. are provided with a row of disks running parallel and forming a toothing area, these disks being arranged approximately perpendicularly on the plane of the carrier and parallel to each other, with their wide sides and in which at least a certain number of these discs are toothed to form the teeth of the toothing region at the longitudinal edge opposite the carrier. an elongated carding card for carding textile materials, of the type in which the discs of the disc array are held on a carrier by fastening means provided on the carrier; Cart herein with reference to a carding board refers to any type of cart 1 which is provided with at least one carding board according to the invention.
For example, it means rotating flat cart°, cart°, etc.

The carding plate to which the present invention relates can be mounted immovably in the cart, for example between a linear tracker and a rotary flat or similar mechanism, or between a rotary flat or similar mechanism and a drawer. It is often located below the card cylinder, between the transfer and the linear take-in, or at any other location depending on the type of cart.

The carding plate to which the present invention relates is provided on the card so that the carding plate extends in its longitudinal direction parallel to the axis of rotation of the cylinder. The toothing area of the carding plate then extends over the entire width 1111 of the clothing measured in the direction of the axis of rotation of the cylinder, ie over almost the entire working width of the cylinder. Clothing of the cylinder means a strip greened with hooks or teeth.

The cart can be provided with one carding board or multiple carding boards to which the present invention relates.

That is, the carding board to which the present invention relates does not refer to a roller on which cards rotate, but refers to a stationary carding board that rotates frequently.

A number of such carding plates, each of which is formed by a single row of disks, are placed parallel to each other in the direction of rotation of the cylinder of the cart and at a distance h,
For example, it is known to provide a linear take-in and a rotating hook between the rotating flat of the card. However, the required precise adjustment of the carding board is difficult;
It also takes time. In addition, the intermediate spaces between these carding plates create a work-related air flow that significantly contaminates the cart and its surroundings. This also prevents fiber orientation. Therefore, attempts have been made in the past to suck this air flow by means of air suction devices. However, this requires high construction costs, increases operating costs, and has a negative impact on the carding process.Furthermore, the carding plates of the J-shira must be adjusted individually and with respect to each other. Therefore, it is an object of the present invention to provide a method of the above-mentioned type for improving the carding operation, which increases the assembly effort and risks insufficient adjustment. It's about making a carding board.

This problem is solved according to the invention by the structure according to claim 1.The carding board according to the invention on the one hand improves the carding operation by making it possible to simplify the structure, while on the other hand it It is possible to replace the adjacent carding board with Vg.

Also, because of their large width, the carrier plates can be constructed with less rigidity than carding plates, each of which has only one toothing area.

The same applies to carding work, and it is easy to adjust the carding board.

This can be done with great precision. This is because the toothing area does not require any individual adjustment.

In the carding plate according to the invention, the discs are arranged at intervals from each other in the direction of rotation of the cylinder. The carding plates are in contact with each other or almost touching each other relative to each other to compensate for manufacturing tolerances and radial sliding of the disk row in the longitudinal direction. III, it fits. This also works well for curving and franging operations. In particular, there is a slight increase in dust generation, which eliminates the need for dust suction in this location, and the risk of contamination of the plow area, the risk of getting caught in the fibers, and the risk of fiber clogging as well. or excluded altogether. With the carding plate according to the invention, the occurrence of drafts, clogging and fouling caused by the known arrangement of multiple carding plates spaced apart from one another is also avoided.

The carding plate according to the invention is advantageously provided with each unique toothing area (instead of the known multiple carding plates for mounting on a cart), one after the other. The overall width of the arrangement of the toothing areas is considerably greater in the carding plate according to the invention, and generally has only one toothing area and is even wider than the width of the toothing area of known carding plates. It is possible to set the size several times larger.

Since a large number of disc rows are mounted on the carrier, an additional fzoj capability of improving the carding operation is obtained by differentiating at least two mutually bordering toothing areas of the novel carding plate according to the invention. This can be achieved by providing a The purposeful structure of this pothole is particularly the following points. at least two mutually abutting toothing regions having teeth with different tooth heights and/or different tooth profiles and/or at least two mutually abutting tooth discs of tooth disc rows having different tooth heights and/or teeth with different tooth profiles; The number of teeth or the tooth pitch is different and/or the at least two mutually adjoining toothing regions have different tooth density profiles and/or different guiding angles.

The tooth density, i.e. the number of teeth on a single surface @R in the tooth working area, increases from tooth working area to tooth working area in the direction of cylinder rotation, and/or the tooth height increases from tooth working area to tooth working area. The shape of the teeth becomes smaller in the direction of cylinder rotation, and the shape of the teeth is changed from tooth working area to tooth working area in the cylinder rotation direction so that finer carding is performed.
and/or it is advantageous to design the toothed disk with a large tooth pitch.

That the guiding angle of the toothing can likewise be varied particularly advantageously allows passage-free formation of the entire arrangement of the fungal working field of the carding board. In this case, the term "no passage" means that the entire arrangement of teeth extends between the teeth from the edge of the entire arrangement of teeth in the upper working direction of the entire arrangement of teeth with respect to the upper working direction of the entire arrangement of teeth with respect to the fiber movement direction. This means that they would like to have a straight Kei passage leading to.

Various configurations are possible for fixing the disk array on the carrier. For example, it is possible to glue each of the tooth discs onto a carrier plate and to fasten these carrier plates to the carrier, but this requires a large amount of expenditure. In order to create particularly good fixing possibilities, the configuration according to claim 5 is adopted.

Teeth work! It is possible to combine the disks into seven packets, or by combining them into a large number of parallel packets arranged one after the other - in this case the side packets are grouped together by at least one fixed device, and the packets are The width of this toothing area is not lost due to the m- fastening means which are fixed on the carrier by the fastening device +' (which engages in one or more second gaps). and narrow it down to the phase t'lfl (k
This makes it possible to extend the arrangement of the gold tooth working area over the entire width of the carrier, thus eliminating the need for the carrier to be unnecessarily wide.

Since the discs of the packet are already stacked together by at least one fixing device before they are attached to the carrier, the discs can already be assembled into a packet forming a structural unit at the manufacturing plant. As a result, the demand for high precision can be solved without any problems.

In this way, it is possible to quickly and simply fix the packets on the carrier beforehand, for example in a spinning mill. It's the building.
By grouping the disks of a disk array into one or more packets, it is easy to exchange a disk of a packet for a new disk by exchanging the corresponding packet of the new disk with the old packet. can be done quickly and without problems. It often happens that there are disks to be replaced only in a limited portion of the disk row, K i -, when the remaining disks in the disk row are still fully functional, i.e., need to be replaced. Ru.

In this case, in order to facilitate exchange, a disk array is formed by a large number of packets located in parallel with each other. In that case, when exchanging areas bordering disks in a disk array, generally only one or two of these packets are exchanged17, and the remaining packets need to be exchanged. In a simple manner, it is possible to arrange the mutually parallel tooth discs of one packet at an acute angle to the longitudinal direction of the carrier, ie to form an acute guiding angle. However, when making the packet, it is possible to arrange the disks in pairs in the longitudinal direction of the packet (with a desired guiding angle). In this case, the packet is shaped like a parallelogram. In the case of an IC, the corner angle of this parallelogram is 4 degrees even when the packet is separated from the punching body by 11" and transported because of the frictional force that occurs between the many discs of such a pack. During assembly, they are also held together by the supporting body.For this purpose, it is necessary to hold the I-isks of the packet together sufficiently strongly by means of at least one fastening device.

Also, very good retention of the individual packets on the carrier is achieved. This is also advantageous for the carding operation, since the back side of the disc fits tightly onto the support surface of the carrier.

so that the fixing means engages a recess in the disc of the packet;
The pressing force of the packet against the supporting body also becomes uniform. This is advantageous in that the fixing means comprises a bar-like profile passing through the second passage of the packet, this bar-like profile being provided with a threaded hole extending transversely to its longitudinal direction, This is achieved by screwing in the threaded hole a tensioning means, preferably a fixing screw, which is supported on the carrier. When this fixing screw is tightened with a torque wrench, a very uniform pressure force on the carrier is achieved over the entire length of the packet.

The formation of this fastening means is particularly simple in construction and
A simple assembly of packets into -+1 carriers and a particularly simple exchange of packets with new packets is possible.

This arrangement also works well for carding operations, since a high accuracy of the discs can be achieved.

In addition, the fixing mode of the discs allows for a more precise adjustment of the position (iq) of the discs, so that in at least many cases there is no need for post-adjustment of the toothing area and/or post-grinding of the teeth after assembly on the carrier. In particular, for this purpose, the second channel of the packet is formed with a neutral cross-section and the fixing means is provided with at least one rod-shaped feature which likewise has a neutral cross-section or cross-sectional area;
This rod-like form is brought into contact with the inclined surface forming the under-/J-side surface of the second passage. This ensures a very precise self-adjustment of the packet when fixing it on the carrier, so that the disk is located very precisely within the packet.

Instead of forming the recess forming the second passage of the disk of the packet with a useless profile, the recess with 1. often has another suitable profile, for example a T-shaped profile. In this case, a bar of rectangular profile, for example, may be placed in this second channel, advantageously sometimes with lateral play, or the shoulders of the disc forming a T-shape in this recess. such that a tension is applied in the direction of the carrier in order to hold the packet on the carrier by a fixing screw or the like supported on the carrier and screwed into the carrier. It is inserted with a slight play.

Generally, it is sufficient for the packet to have only one second path. Advantageously, the recesses forming this second channel of the disc and located in the same row as one another are of equal design.

The mutually aligned recesses forming the first channel of the disk can also be designed equally.

For ease of manufacturing the discs, it is advantageous for each disc to have a constant thickness and be made of stone. In this case, it is advantageous if all toothed discs of the disc row have the same thickness relative to each other.

Since the toothed discs must be spaced apart from each other, in this case, in addition to these toothed discs, further spacer discs together form a packet, in which case at least one spacer disc is placed between each two toothed discs in the middle. is inserted into.

The intermediate disk and spacer disk are metal! It is advantageous for the Samurai to be made of steel.

It is also possible to design the toothed disc in such a way that its legs are thicker than its multi-toothed toothed region. In this case, if the thickness of the legs provides the desired spacing between the tooth areas of adjacent tooth discs,
It is possible to mount such discs directly in parallel in rows. That is, in this case, it is unnecessary to provide a spacer disk.

Although it is generally advantageous and sufficient to provide a single second 7Ij circuit in a packet reservoir, in some cases it may be necessary, for example, to secure the packet more evenly or to improve the precision of its arrangement. It is also possible to provide two or more such second passages for further increase.

The teeth of the disc can be formed in any suitable manner. If desired, it is also possible to provide the tooth sharp edges of the toothed disk along a geometrical force arc whose radius corresponds closely to the radius of the cylinder.

The packet as a whole is provided with two first passages, which passages are suitably provided symmetrically to each other with respect to the longitudinal center plane of the packet, in particular in the vicinity of both longitudinal sides of the packet. In most cases, only one first passage 4'f is sufficient if this passage lies approximately in the longitudinal center plane of the packet.

In many cases it is also possible to provide more than two passages, especially if a high individual stiffness of the packet is achieved by means of a fixing device through which the first passage passes.

The recess in the disc forming the first passage may advantageously be a hole.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings.

The longitudinally elongated carding plate 10 shown in FIGS. 1 to 4 is provided with a solid strip-shaped carrier 11 made of aluminum or other metal and having a constant cross-sectional shape. If the card is provided with a carrier whose longitudinal direction is - extending parallel to the axis of rotation of the cylinder of this cart and which is immovably mounted on the card - this carrier is extremely stable. Therefore, this carrier often bends during operation. The carrier has in this embodiment a total of four mutually parallel discs 12a to 12d of equal width, each of which forms one toothing area 18 and is shown in FIG. They are arranged closely one after the other in the direction of rotation of the cylinder of the cart (in the direction of the arrow), indicated by a dashed line and reference numeral 2B. Each of such tooth working areas 1a is
Each unique row 12a to 12d of discs 15.16 abutting each other in parallel, flat and on their wide sides.
are formed by teeth 17 of toothed disc 16 spaced apart by spacer disc 16 of C.

The disks 15, 16 of each such disk row 12a-12d are combined to form a single packet 21 or a number of packets present in the same row. In this case, the disks 15,16 of each packet 21 are each held together by two fastening devices 19.

Each packet 21 consists of a number of disks 15, 16 of the same length, formed by stamping, with a thin, straight back edge 14. In this case two types of disks 15.1
6 are provided, one type being a disk 15, for example the disk according to FIG. 5, and the other type #'i, a toothless spacer disk 16, for example the disk according to FIG. The tooth discs 15 of the individual toothing areas 18 are equal to one another, and therefore the spacer discs 16 are also equal to one another.

1-The tooth discs 15 of the different tooth working areas 18 depend in particular on the tooth profile, tooth height, tooth pitch and number of its teeth 17.
− It takes a different shape. The spacer disks 16 of the toothing regions 18 are likewise designed identically to each other and can be equal for all S working regions 13 on the gates 12 or have different thicknesses, for example for the two toothing regions 13; -1, it is possible to vary the tooth density in this toothing region 18. The tooth density in the tooth working area and e means the number of teeth per unit area. Tooth working area 130 Teeth 17 are tapered from one tooth working area to the other tooth working area in the cylinder rotation direction (direction of arrow A), and the teeth have a large degree of flute.
The height of the teeth decreases.

The length of each of the toothing areas 18 is (j), which corresponds to the working width of the cylinder of the card in question.

The tooth discs 15 and the spacer discs 16 forming the toothing surface 18 are parallel to each other and form their straight back edges 14 to form the flat or surface ladle resting surface 20 of the carrier 11. Although it stands vertically above, it is cut out and shown in Fig. 1. As shown in the example of the row of discs, it may also be provided at a guiding angle a with respect to the longitudinal direction of the toothing region 13.

1. Therefore, in this case, the outline of the Dis array has a parallelogram shape. In the embodiment according to FIG. 1, the guiding angle a from the toothing region to the toothing region is oriented 1. Therefore, in this embodiment, the toothing area has a staggered arrangement. That is, the guide angle a is formed differently from the toothing region 18 to the toothing region 1B, and in some cases is formed at 90°, in the latter case the contour of the toothing region 18 being rectangular. By providing a large number of toothing regions 18 in close succession, in which case different guiding angles a from toothing region 18 to toothing region 18 can be provided, the entire toothing region can be This entire toothing area has no passage, that is, it extends across the entire arrangement of the toothing area 18 in the running direction of the #1 fibers, and the fibers run through without being diverted to Lm. Leave plenty of space.

This is further improved by this carding board 10.

As seen in FIG. 2, the four flat mounting surfaces 20 of the four disc rows 12a to 12d are provided at a slight inclination to each other, and the remaining parts are removed in detail by pressing. Adaptation of the toothing area to the part indicated by dash-dotted lines at 28 of the cylinder of a card (not shown), which may be a rotating flat cart, a carding machine or another cart 0, takes place. Cylinder lining curvature 01
0t7j, in order to further improve the adaptation of this toothing area to
As shown in the figure, the linear shape is a curved line 23' having a geometrical convex arc shape whose radius corresponds approximately to the radius of the cylinder 2B.

The toothing area 13 of the carrier 11 is, for example, 1 m to 1.50 m.
It has a length of 1, but can be made shorter or longer depending on the card.

In the embodiment according to FIG. 8, the illustrated χ disk row 12a is formed by a single packet 21, shown broken away, consisting of a tooth disk 15 and a spacer disk 16, the flesh of which is on its wide side. The two fastening devices 19, only one of which can be seen in the drawing, abut each other and pass through holes in the discs 14 and 15, and are firmly pressed into place.

Therefore, when this packet 21 is lifted off the carrier 11, it is held together by this fixing device 19, and this holding state is also held firmly on the companion body 11, and thereby this packet 21 is lifted from the carrier 11.
The overall at perch retention on 1 is improved.

This packet 21 consists of from several six to several thousand disks 15.16, depending on the thickness of the disks 15.16, of which only a few are shown in FIG.

A spacer disk 1 is provided between each two tooth disks 15.
6 is provided. Two circular holes 24 pass through each of these disks 15 and 16 (see FIGS. 6 and 6), these holes being located near both longitudinal ends of the disks. These holes 24 form two parallel rows of holes within the packet 21, which form two straight first passages 24' through the packet 21 ( 8 and 7), each passage 24' forms a tensioning device 1. A fastening device 19 passes through it, which does not project outwardly beyond this passage. In this way, packets with possibly a large number of equal discs 15, 16 are arranged on the carrier 11 in a row of discs in parallel with each other without any spacing. If only the existing tooth disc has to be replaced, it is easier to replace the worn tooth disc.

The fixing device 19 consists in this embodiment of a straight gold pull rod 26 and a fixing screw 27. The draw rod 26 is provided with a frusto-conical head 26' at its end, by means of which the last eight discs 15, 16, as can be seen from FIG. The fixing screw 27 is likewise provided with a frusto-conical head 27', and is fitted so as to be correspondingly enlarged and to be sunk in the shape so that no reaction force is obtained in the bore 24. The two disks 15, 16 are fitted into correspondingly widened holes 24 in the same way, so that the reaction force is obtained here, and the hexagonal threaded hole in the tension rod 26 The entire set of discs 15, 16 of the disc row 12& forming the gearing area 1B therein are inserted together into one bucket) 21.

The straight tension rod 26 has an axis 2C of circular cross-section, which lies in the bore 24 of the disk 15, 16 through which it passes, with sliding play.

Each of the disk rows 12a to 12d itself forms such a packet 21, in which case each packet 21 has two fastening devices f! passing through both first passages 24'.
719.

Therefore, all disks 15 of this nokukerato 21
, 16 consistently fit into each other on their wide sides.

Each such packet 21 constitutes a structural unit which rests with its straight back edge 14 of its discs 15, 16 on the associated flat force surface 20 of the carrier 11. There is. Carrying individual packets 21 on carrier 11
A fixation 12 is provided on the top, and thereby a uniform and immovable adaptation of the carrier 11 to the associated surface 20 and self-adjustment of the packets takes place, with the disk rows 12a to 12
In order to achieve the close-contact front and rear arrangement of d, the following configuration is adopted.

In each disk 15,16 of each packet 21, the lower and centrally calorific recesses 80, which are open L' towards the carrier 11, are all of the same shape and are aligned with each other in 21 in the packet 21. It is formed to be. These recesses 80 thus provide a consistent path 3 within the packet 21.
0' (second path), and this path
It extends over the entire length of this packet 21 along its central longitudinal axis and has a calorimetric cross section. Accordingly, an inclined undercut surface forming a "C" undercut is formed. All the second JO passages 80' of the buckets 21 have equal cross-sectional size and shape. Equivalent to 17, U
Advantageously, the length is between 3 and 12 cm. Into the second passage 30' of each packet 21, as can be seen from FIG. 4, is inserted a solid rod-shaped feature 32. The profile of this rod-like profile consists of an inexhaustible area and a rectangular area. The head 34 of the rod-like profile 82, which is of infinite cross-section, is provided with an inclined side surface 38 which is identical to the inclined flat undercut 81 of the second channel 30' of the bucket 21. forming an angle. In this case, the width of the flat end surface of the head 84 of the rod-shaped member 82 is the second width.
is somewhat smaller than the width of the flat bottom of passage 80'. This allows the rod-shaped feature 32 to enter the second passage 80' without any problems. This flocculent form extends over at least the entire length of the second passage 30', so that the entire disc 15.16 of the packet 21 in question is covered by the second passage 80.
The shape is brought into contact with the solid body weight at the ``γ undercut dri81''.

The rod-like shape 32 passes through the opening 41 of the second passage 80' facing the carrier 11 [2] and has a leg 86 whose cross section is rectangular and extends along the long side of this leg in the corresponding mounting surface 20 of the carrier 11. Guide the side 1. It protrudes into the longitudinal groove 86 with slight sliding play. Threaded holes 87 are formed at the same intervals in this leg portion 35 , and a fixing device 39 is screwed into the screw holes of the carrier 11 .
It is sunk into the hole, and its head is supported by the stepped portion of the hole via a washer. By rotating K this fixing device 39, the rod-shaped profile 32 is moved deeper into the associated longitudinal groove 86 in the direction of the carrier 11, and by the pull the rod-shaped profile 82Fi, this packet 2
Pull all the disks 15, 16 of 1 firmly against the corresponding mounting surface 20, thereby making this packet 2
All discs 15, 16 of 1 are firmly pressed against the bearing surface 20 of 41 (special holiday 11) with significant force until they cannot move any further. The screw 39 and the rod-shaped profile together form a fixing means. , this fixing means includes a passage 80' and a bar-shaped member 82.
Packet 21 and its disk 15 were created through the cooperation of
．． 16 are press-fixed onto the abutment surface 20 of the carrier 11 while simultaneously accurately aligning and adjusting the fixing action.

This eliminates, at least in most cases, the need for further adjustment of the packets 21 on the carrier 11 and therefore also the need for regrinding of the teeth 17.

Illustrated in Figure 11. As a result, the four disk rows 12a to 12d according to FIGS. be done. The width of the carrier 11 is optimally utilized by the toothing area 18. This is because this width covers the entire width of the carrier.

This carding board has a number of advantages, including, among other things, a good carding operation and low dust generation, and the prevention of clogging of the clothing of this carding board formed by the disk rows 12a to 12d. This has the advantage that the packet 21 can be assembled easily, quickly and accurately without any problems, and the packets can be easily exchanged.

Up to four or more disk rows can be provided on the carrier 11.
