    专利说明:

    The invention relates to a storage tray for sliver according to the preamble of claim 1.
    In a known storage tray (EP-A-0 670 281), a round tube is converted as a starting material to a spatially curved band channel. Following the outlet bend, a straight line is arranged in the semi-finished product, which is separated at the completion of the band channel. The outlet of the band channel is designed such that it terminates flush with the bottom of the turntable. The bottom of the turntable has a through opening whose inner diameter is greater than the outer diameter of the outlet of the band channel, whereby a distance space is formed. The distance space and the opening are introduced when casting the turntable. The plate-shaped cover of the turntable on its underside also has a through opening, wherein the inner diameter of the cover is flush with the outer wall of the Bandrohrauslaufs. When mounting the spout of the band tube spout is inserted through the opening of the turntable through in the opening of the cover. Subsequently, a casting material is poured in such a way that the band channel is fixed to an outlet with the casting compound. In this case, the pouring point is covered by the plate-shaped cover such that only the free cross section of the band channel is free. The disadvantage is the considerable production and assembly technical effort. In particular, care must be taken when pouring the band channel with the casting material in the turntable. The casting compound is expensive. In addition, the significant amount of time required to close the distance space between the turntable and the Bandrohrauslauf. Finally, the casting compound in the region of the connection of the banded pipe outlet to the cover is critical, since in the event of damage or the like, the casting material can get stuck in an unwanted manner, which leads to an impairment of production and quality.
    The invention is based on the object to provide a storage tray of the type described above, which avoids the disadvantages mentioned, which is particularly simple in construction and allows easy production and assembly.
    The solution of this object is achieved according to the invention by a storage tray with the features of independent claim 1.
    Characterized in that the outlet of the band channel is connected by means of a bonding method for metallic materials, preferably by laser welding, with the top of the turntable or with the top of the cover, eliminating the fixation of the band channel by a casting compound and the associated production costs.
    The dependent claims have advantageous developments of the inventive storage tray to the subject.
    Another aspect of the invention relates to a method for producing a storage tray as described above, according to claim 18.
    The invention will be explained in more detail with reference to exemplary embodiments illustrated in the drawings.

    Fig. 1 shows a card, e.g. Trützschler card TC, with feed roller 1, dining table 2, lickerins 3a, 3b, 3c, drum 4, pickup 5, skimmer 6, squeezing rollers 7, 8, nonwoven guiding element 9, trimming funnels 10, take-off rollers 11, 12, revolving lid 13 with cover deflecting rollers and flat bars, Jug 15 and Kannenstock 16. The directions of rotation of the rollers are shown with curved arrows. M denotes the center point (axis) of the drum 4. 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4. The arrow A indicates the working direction. The card is preceded by a flock feed device 17. In the storage tray plate 18, the storage tray 19 is rotatably mounted. The storage tray 19 comprises a belt channel 20 with an inlet and an outlet (see Fig. 3) for sliver and a turntable 21, on the underside of a cover 22 (see Fig. 3) is present. With simultaneous rotation of the pot 15, the sliver 14 is deposited cycloid shape in the pot 15, whereby a uniform filling of the pot 15 with sliver is possible. With A, the working direction is designated.
    Referring to Fig. 2, a route, e.g. Trützschler line TD, a drafting system 26 with a drafting system inlet and a drafting system outlet. The slivers 27 come, coming from cans, not shown, in a tape guide and, pulled by draw-off rolls, transported past a measuring member. The drafting system 26 is designed as a 4-over-3 drafting system, i. it consists of three lower rollers I, II, III (I exit lower roller, II middle lower roller, III input lower roller) and four top rollers 28, 29, 30, 31. In the drafting system 26, the distortion of the fiber structure 27 is made of several slivers. The delay is composed of pre-delay and main delay. The roller pairs 31 / III and 30 / II form the Vorverzugsfeld and the roller pairs 30 / II and 29/28 form the main drafting field. The drawn slivers (nonwoven fabric 32) reach in the drafting outlet a nonwoven guide 33 and are pulled by means of the take-off rolls 34, 35 through a belt hopper 36, in which they are combined to form a sliver 37, which then in a fiber cane ring 16 and storage tray 19 in sliver rings 38 in a jug 39 is stored. The pot 39 is formed as a rectangular can and alternates during the tape storage below the cover plate in the direction of arrows C and D. The storage tray 19 includes a spatially curved band channel 20 for sliver 37 and a turntable 21, on the underside of a cover 22 is present. With B the direction of the fiber structure 27 is designated by the drafting system 26. The storage tray 19 is arranged in a storage tray plate 18 (not shown in FIG. 2), which essentially corresponds to the storage tray plate 18 according to FIG.
    3, the sliver 37 (see Fig. 2) enters the inlet 20a of the spatially curved band channel 20, passes through the band channel 20 and then exits the band channel 20 at the outlet 20b. The band channel 20 is arranged eccentrically in the turntable 21. The turntable 21 rotates during the storage of the sliver about a rotation axis 41 in the direction of arrow E. The rotation of the turntable 21 about the rotation axis 41 creates a circular (annular) storage of the sliver in the can 39th
    The band channel 20 is connected in the region of its inlet 20a with a plate holder 21a. In the region of its outlet 20b, the band channel 20 is firmly welded to the upper side 22 of the cover 22 (see FIG. 5). The underside 21 of the turntable 21 is provided with the cover 22, e.g. a cover made of stainless steel. Stainless steel is wear-resistant and low-friction with respect to the deposited in the pot 39 sliver 37. In addition, a mechanical processing (grinding, polishing) of the bottom of the turntable 21 is avoided, which preferably consists of a cast aluminum or an aluminum alloy. The cover 22 is arranged snugly against the underside of the turntable 21 and is e.g. attached by gluing. The edge 22 *, 22 ** of the cover 22 is bent and is located on the turntable 21 at. The turntable 21 has a through opening 21a (see Fig. 3a), which allows the passage of the sliver 37. The transitions 23, 23 at the outlet of the through opening 22a of the cover 22 are rounded. The cover 22 also has a through opening 22a (see Fig. 3a) for the passing sliver 37.
    As Fig. 3a shows, the opening 21a has a larger diameter than the opening 22a. In Fig. 3b, the connection of the outlet 20b of the band channel 20 with the cover 22 and the turntable 21 is shown in ready state. The peripheral edge of the tube end of the band channel 20 sits on the top of the edge of the opening 22a festgeschweisst on. The inner wall surface of the spout 20b of the band channel 20 terminates flush with the inner wall surface of the opening 22a. Between the outer wall surface of the spout 20b and the inner wall surface of the opening 21a there is an annular cavity which is closed from below by the cover 22 and open at the top. This cavity is filled with a molding compound 50, which serves to stabilize and connect the band channel 20 with the turntable 21. In this way, the casting compound 50 comes into contact neither with the sliver 37 to be deposited nor with the fiber sliver rings 38 deposited (see FIG.
    The outlet 20b of the band channel 20, e.g. is made of a stainless steel tube, is placed flush with the top 22 of the closed cover 22 from below in Fig. 4a flush. By a welding process, e.g. Laser beam welding, the band channel 20 and the cover 22 are firmly connected together. With 25, the circumferential weld is designated. The laser beam penetrates the cover 22 from the lower side 22 and welds the open end (edge) to the outlet 20b of the band channel 20 on the upper side 22 of the cover 22 (see Fig. 5). The fact that the band channel 20 and the cover 22 are made of stainless steel, a trouble welding connection is made possible by laser beam welding.
    In laser beam welding, a high-energy laser beam is converted into heat upon impact and penetration into the workpiece. The material melts and forms the weld during solidification. The weld seam is so thin that usually no additional material is required. Welding is carried out in vacuo or under inert gas, sometimes in a free atmosphere. By bundling the beam to a diameter smaller than 1 mm, the focal spot receives a high energy density and temperatures up to 20,000 ° C. The depth of the seam depends on the material to be welded, the power of the laser, the beam diameter and the feed rate.
    Advantages of laser beam welding:• Can be used for almost all materials and material combinations• High feed rate• Small seam width• Oxide-free welds when welding under vacuum or under protective gas• Minor distortion of the components• Easy to automate• High-strength welded connection
    The laser device for laser beam welding is designated 48 in FIG. 4a. For further details of a laser device, see the description below for a laser device 42 for a laser beam fusion cutting.
    Subsequently, the through opening 22a of the cover 22 from the bottom 22 of the cover 22 forth by a separation method, e.g. Laser cutting, introduced. For this purpose, a cutout part (not shown) is cut out of the closed cover 22 by cutting, as shown in FIG. 4b. In this way, the through opening 22a is formed in the cover 22. Subsequently, the transitions 23, 23 at the outlet of the through hole 22a of the cover 22 are ground and polished, so that adhesion or snagging of fiber material is effectively avoided.
    The required for generating a continuous kerf relative movement between the laser beam 43 and the cover 22 can be realized in different ways. For laser separation, the cover 22 can be moved under the stationary laser beam 43, for example by means of an X / Y coordinate shifter. Furthermore, for laser cutting either the laser source including the cutting head can be moved over the cover 22 or a movable mirror system can be guided together with the cutting head ("flying optics") between the stationary laser device and the cover 22.
    When laser beam fusion cutting according to Fig. 4b by means of a laser device 42 is a laser beam 43 for cutting, which is generated by means of gases (gas laser) or crystals (solid state laser) and by at least one lens 47 on a very small area Surface 22 of the cover 22 is focused (bundled). The stainless steel of the cover 22 melts or evaporates and is blown from the kerf by a gas jet 45. The cutting gas 46 is an inert gas, usually nitrogen or argon, and is introduced into the cutting nozzle 47 through an inlet.
    The laser beam 43 can operate in free space or through a medium such as oil or water, are performed. The laser power and the cutting speed must be adapted to the material type (stainless steel) and material thickness.
    The invention has been explained using the example, wherein the band channel 20 is connected to the top 22 of the closed cover 22 and then the through opening 22a of the cover 22 is introduced. The invention likewise includes a design according to which the through opening 22a is introduced into the closed cover 22 and subsequently the band channel 20 is connected to the upper side 22 of the cover 22.
    6, the sliver 37 (see Fig. 2) enters the inlet 20a of the spatially curved band channel 20, passes through the band channel 20 and then exits from the band channel 20 at the outlet 20b. The band channel 20 is arranged centrally in the turntable 21. The turntable 21 rotates during the storage of the sliver about a rotation axis 41 in the direction of arrow E. The rotation of the turntable 21 about the rotation axis 41 creates a circular (annular) storage of the sliver in the can 39th
    The band channel 20 is connected in the region of its inlet 20a with a plate holder 21a. In the region of its outlet 20b, the band channel 20 is firmly welded to the upper side 21 of the turntable 21. The underside 21 of the turntable 21 is provided with a cover 22, e.g. a cover made of stainless steel. Stainless steel is wear-resistant and low-friction with respect to the deposited in the pot 39 sliver 37. In addition, a mechanical processing (grinding, polishing) of the bottom of the turntable 21 is avoided, which preferably consists of a cast aluminum or an aluminum alloy. The cover 22 is arranged snugly against the underside of the turntable 21 and is e.g. attached by gluing. The edge 22b, 22c of the cover 22 is bent and is located on the turntable 21 at. The turntable 21 has a through opening 21a (see Fig. 6a), which allows the passage of the sliver 37. The transitions 23, 23 at the exit of the through hole are rounded. The cover 22 also has a through opening 22a (see Fig. 6a) for the passing sliver 37.
    The outlet 20b of the band channel 20, e.g. 7 is made flush with the top 21 of the closed turntable 21, e.g. made of cast aluminum, placed from above. By a welding process, e.g. Laser beam welding, the band channel 20 and the turntable 21 are firmly connected. With 24 the circumferential weld seam is designated.
    Subsequently, the through hole 21a of the turntable 21 is formed from the lower side 21 of the turntable 21 by a separation method, e.g. Laser cutting, introduced. For this purpose, a cutout part (not shown) is cut out of the closed turntable 21 by cutting, as shown in FIG. In this way, the through opening 21a is formed in the turntable 21st
    The time required to produce a continuous kerf relative movement between the laser beam 43 and the turntable 21 can be realized in different ways. For laser separation, the turntable 21 can be moved under the stationary laser beam 43, for example with the aid of an X / Y coordinate displacement device. Furthermore, for laser cutting either the laser source including the cutting head can be moved over the turntable 21 or a movable mirror system can be guided together with the cutting head ("flying optics") between the stationary laser device and turntable 21.
    When laser beam fusion cutting according to FIG. 8 with the aid of a laser device 42, a laser beam 43 is used for cutting, which is generated by means of gases (gas laser) or crystals (solid-state laser) and by at least one lens 47 on a very small area Surface 21 of the turntable 21 focused (bundled) is. The aluminum of the turntable 21 melts or evaporates and is blown from the kerf by a gas jet 45. The cutting gas 46 is an inert gas, usually nitrogen or argon, and is introduced into the cutting nozzle 47 through an inlet.
    The laser beam 43 can operate in free space or be guided by a medium such as oil or water. The laser power and the cutting speed must be adapted to the material type (aluminum) and material thickness.
    The invention has been explained using the example, wherein the band channel 20 is connected to the top 21 of the closed turntable 21 and then the through opening 21a of the turntable 21 is introduced. The invention likewise includes a design according to which the through opening 21a is inserted into the closed turntable 21 and subsequently the band channel 20 is connected to the upper side 21 of the turntable 21.
