Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for dispensing material consisting of coarse fibers or particles onto a moving porous carrier web, the method comprising dispensing said material into an elongated dispensing vessel located above said carrier web. and maintaining the fluidized material in air in a fluidized state, and slowly expelling the fluidized material from the dispensing vessel in a wide stream through a screening device provided in the dispensing vessel. The present invention relates to a method and apparatus which are directed towards said carrier web and wherein said wide stream of material is produced by suctioning air from the underside of said carrier web.

A method of this type and an apparatus for carrying out the method are disclosed in British Patent No. 1207556. The fibers are packed into a cylindrical butt having a flat perforated bottom, which constitutes a screen wall portion of the screen device, positioned parallel to and in close proximity to a moving carrier web lying transversely below. . The agitation device used to stir the fibers near the bottom of the screen includes two vertical rotor shafts mounted in a planetary gear system above the vat; The lower end is provided with radial, vertically oriented impeller blades that swirl within the bottom material layer. A suction box is arranged below the vat-moving web to draw a flow of air through the fibers in the vat, the screen bottom and the web, thereby sucking out loose fibers near the bottom. is deposited on the moving web in a fairly uniform layer. The web binds the layer and moves it to a curing position where the layer is rendered into a nonwoven sheet material.

The purpose of agitating the fibers is to keep the fibers mixed with air and to constantly realign them with respect to adjacent fibers to ensure even distribution of the fibers onto the web, while also allowing the fibers to be distributed as quickly as possible. The purpose is to give the suction air an opportunity to pass through the narrow holes in the screen wall section. The degree of fiber realignment is greatest where the impeller blade edge velocity is highest. That is, effective fiber agitation is obtained in the annular area adjacent the edge portion of the outer impeller blade. However,
Due to the tendency of centrifugal force to blow the fibers out of this annular area, the dispensing capacity of the distributor increases to some extent as the speed of the impeller increases, but thereafter the dispensing capacity decreases. It has thus been found that the maximum dispensing capacity obtainable in practice is not as high as desired.

According to another known method, the fibers are fed into a cylindrical space between a horizontally rotating drum and a screen shell, the drum being provided with a very large amount of material that serves to disassemble and rearrange the fibers. It carries a number of radially projecting needles. However, the fibers tend to be moved rapidly through the space with the drum surface, so that the speed of the needle with respect to the fibers is not as high as the needle speed itself, and therefore the fibers are The re-needle capacity and fiber dispensing capacity are relatively low. In addition, in order to uniformly distribute the fibers over the entire surface of the web, the fibers must be uniformly supplied throughout the cylindrical space, and there is a problem in that it is difficult to uniformly supply the fibers. be.

It is an object of the present invention to provide a dispensing method and device that achieves high dispensing capacity and uniformity of dispensing.

According to the invention, one side of the elongated dispensing container along the screen device or outlet screen wall device is oriented in the longitudinal direction of the container and follows a path substantially parallel to the surface of the carrier web. producing a flow of said fluidized material into the dispensing vessel in a direction that does not intersect with said outlet screen wall arrangement; directing the material along the return path along the other side of the dispensing vessel, spaced from and opposite the wall device, and directing material flowed along the return path toward the outlet screen wall device; producing a recirculation of material flow within said dispensing vessel by guiding the material in a manner similar to that of said dispensing vessel; and supplying fresh material into said circulating material; , a force application device configured to apply a force to the flow of material flowing along the exit screen wall arrangement to positively displace it outwardly; creating a moving component oriented transversely to the flow direction of the material flow and directed toward discharging the material through the exit screen wall arrangement, thereby increasing the distribution capacity of the material. A method of characterizing is provided. Also provided is a dispensing device for implementing the method. The material in the dispensing container is agitated by whipping the material just inside the screen wall portion of the screening device. In addition, in this specification,
The terms "whipping" and "whipping" refer to beat members having a relatively narrow width throughout the material.
In other words, by repeatedly moving the whip member at high speed, the arrangement of constituent substances of the material is disturbed along the movement path of the whip member through the material. It is used to clearly separate the constituent substances of the material from each other. When dry fibrous or other bulk material is whipped in air in this manner, the fibers or particles remain fluidized with the air and the whipping causes the fibers or particles to The pieces are suitably rearranged. The fibers or particles are thus easily drawn out through the holes in the screen wall section, thereby ensuring a high dispensing performance. As the whipping speed increases, the degree of fiber or particle rearrangement increases and the dispensing performance increases within wide limits. As is clear from the above,
Whipping provides a very efficient agitation or agitation of the material and thereby a favorable rearrangement of the constituents of the material; for example, the method and apparatus described in British Patent No. 1207556 describe such efficiency. It is impossible to cause agitation.

In practice, it would be unnecessary to whip material adjacent to all surface areas of the screen wall portion of the dispensing container, but tests have shown that whipping occurs in spaced areas along the screen wall portion of the dispensing container. It has also been found that excellent results are obtained when the material is allowed to move relatively slowly from one whipping zone to the next. Once whipped, the material remains air fluidized for a period of time, and if the whipping is repeated immediately thereafter, the material is moved along the screen wall section to the next whipping position. Thus, fibers or even particles in the flow of material between the whipping locations will be easily distributed through the screen wall portions.

The successive movement of the material from one whipping position to the next can be effected by the whipping member itself. To this end, the whip member is moved in one direction near the screen wall section so as to cause a relatively slow movement of material along the screen wall section. This movement, in absolute terms, is sufficiently rapid but slower than the speed of the whip member.

While the whip member rotates, the tip of the whip member moves in a circular trajectory, but the plane on which the circle is drawn and the surface of the screen wall portion are not parallel but form an angle. This is advantageous and will be discussed in detail later.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

An elongated, generally designated 1 in FIG.
The fiber distribution container has half rounded ends 2
each end portion 2 has a vertical semi-cylindrical upper portion and a semi-conical downwardly protruding bottom portion 6.
and a horizontal semicircular bottom plate 8. The end parts 2 are interconnected by vertical side plates 10 arranged between the upper parts. These members 2, 6, 8, 10 are made from non-porous metal sheet material. Mounted between the side plate 10 and the bottom portion 6 and bottom plate 8 is a screen device or exit screen wall device, generally indicated by the numeral 12, which screen device 12 is permeable to fibers and air and has an end wall. It has a U-shaped cross section corresponding to the portion 2. That is, a flat, horizontal bottom screen wall or screen wall portion 14;
It has two sloping screen wall sections or side wall sections 16. The dispensing container 1 is supported by struts 18 above the horizontal fiber-layered web. The horizontal fiber layered web consists of a fine screen or wire mesh 20 and is stretched endlessly around rollers 22 in the direction indicated by the arrows in FIG. 4 by a drive device (not shown). Driven. A suction box 24 with an exhaust device 26 is arranged below the screen device 12 and the wire mesh 20 and is supported by a beam 19 connected on the struts 18. The intake box 24 is closed at the bottom and sides, and is covered with wire mesh 20.
It has an upper opening 28 positioned closely against the lower surface of the housing, and the upper opening 28 is sealed against the wire mesh 20 by a sealing flange 30. A horizontal sliding gate 32 is provided on one side of the intake box 24, and the horizontal sliding gate 32 has a curved edge portion 34 for controlling the intake area. A bracket 36 supporting a motor 38 is provided in the upper part of one semi-cylindrical shape, and the motor 38 drives four vertical shafts 42 supported by bearings 44 by a chain transmission 40. Further, the bearing 44 is supported on a horizontal bar 46, and the horizontal bar 46 is supported on the side plate 10. The vertical shafts 42 are arranged in a row in the vertically symmetrical plane of the dispensing vessel 1 and each of them is diametrically aligned with one another and serves as a whip member (as will be explained later). Three pairs of elongated rotor members 48 are provided,
The length of the rotor members 48 is also such that during rotation, each tip portion sweeps an area of the sloped screen wall portion 16 a small distance apart, and further the lowermost rotor member 48 They are arranged directly above the wall 14. The lowermost rotor members 48 are all positioned to rotate in a common horizontal plane above the bottom screen wall 14, and the other rotor members 48 are staggered and positioned to rotate in a common horizontal plane above the bottom screen wall 14. They are arranged so that they rotate.
The rotor member 48 constitutes an agitation device for fluidizing the material and imparting a relatively slow movement to the material along the screening device 12 and imparts a lateral direction to the movement or flow of the material. Together they constitute a force application or deflection device for imparting a movement or velocity component in the direction of the screen wall section 16.

Along the opposite side, the dispensing container 1 is provided with an outer wall panel 50 , which together with a plate member 54 for closing the side surface forms a scavenging channel 52 with the side panel 10 . The exterior wall board 50 and the plate member 54 extend downwardly to just above the wire mesh 20 and define a space with a generally triangular cross section between the inclined screen wall portion 16 and the wire mesh 20, and this space is defined by the scavenging channel 52. is shielded from the surrounding air except for the upper opening.
The exterior wall plate 50 has a right angle bend at its lower edge forming an air gate 56 through which a wire mesh 20 carrying a layer of fibers deposited on its surface may pass as described below. It is made possible.

In operation, the vertical shafts 42 are rotated in the same direction so that the tip of the rotor member 48 is moved at a speed of 50 meters per second. This speed is suitable for processing cellulose fibers, for example, but can be varied depending on the desired product. through the bottom screen wall 14 and the screen wall portion 16;
An air flow is generated which is discharged through the wire mesh 20, the suction box 24 and to the outside through the exhaust device 26. Similarly, air is drawn through the scavenging channel 52. Disaggregated material, such as cellulose fiber pulp, is fed into the dispensing vessel 1 through the fiber distribution inlet 58 up to approximately the level of the uppermost rotor member 48 and is agitated by the rotor member 48 . The rotor member 48 thus whips violently through the material. The unidirectional rotation of the rotor member 48 forces the fiber material generally toward the oppositely sloped screen wall portion 16, such that the profile of the material is indicated by the dashed line a in FIG. It becomes like this. The material supported by the inclined screen wall portion 16 is forced by the rotor member 48 to move along the screen wall portion 16;
Overall, relatively slow recirculation flows through the distribution vessel 1 along one side from one end to the other, then around the end and back from one end to the other along the other side. Exercise. As is clear, this flow is approximately parallel to the surface of the wire mesh 20 and does not intersect with the surface. That is, arbitrary parts of the material flow, such as the upper edge and the lower edge, move above the wire mesh while drawing a line substantially parallel to the surface of the wire mesh. The fibers passing through the area swept by the rotor member 48 are rapidly whipped and rearranged until they reach the next whipping area.
Maintain each fluid state. Thus, the sloped screen wall portion 16 and the bottom screen wall 14 are continuously swept by the effectively fluidized flow of fibers, so that the fibers easily cross the bottom screen wall 14 and the sloped screen wall 14. It can be sucked in through part 16. After passing through these, the fibers are deposited onto a wire gauze 20 which separates the fibers from the air and thus forms a sheet of loose fiber material which is then subjected to the desired subsequent processing by the wire gauze 20. is conveyed over the air gate 56 for the purpose of

Some of the fibers have a tendency to adhere to the inner surfaces of the outer wall plate 50 and the plate member 54, but are removed by the downwardly flowing ski abending air (cleaning air) introduced into the scavenging channel 52. This prevents such adhesion. Drawing some of the air towards the wire mesh 20 in this manner allows more air to pass through thinner areas than through thicker areas, thereby causing more fibers to be distributed upwardly adjacent to the screen wall portion 16. Being directed from the zone to such a thin area has the advantage of obtaining a sheet of uniform thickness on the wire mesh 20.
Fibers are distributed at an increased rate from the screen wall portion 16 near the area that is swept closely to the tip of the rotor member 48, resulting in a somewhat uneven distribution of fibers.
The aforementioned advantages substantially offset such disadvantages. The longest passage of fibers from the screen wall section 16 to the wire mesh 20 is located above the screen wall section 16, i.e., at the uppermost rotor member 4.
It will be noted that the portion located near the highest velocity zone of the tip of 8, ie from the most active fiber distribution zone to the wire mesh 20. While traveling along this long path, the fiber is guided into the thin section described above.

The flow of fiber material inside the dispensing vessel 1 is forced upwardly around the semi-conical bottom part 6 at either end part 2 and the guide plate member 6
0 and then the other end portion 2
It moves in a flow in the opposite direction from before. That is, the fiber material moves along one screen wall section 16 from the upstream end to the downstream end and returns at the downstream end guided by the conical bottom section 6 and the guide plate member 60 forming a guide device. It is guided by a path, that is, a path along the other screen wall portion 16, and moves along this path in the opposite direction. At the downstream end of the return path, it is guided by a similar guide device as described above and returned to the path along the one screen wall section 16, thus repeating the circulation of the material flow. . During the redirection of the flow of fiber material, heavy particles or masses of fiber or other scrap material are concentrated in the area above the semi-conical bottom part 6 at the circumference and are removed in this area. It is being done. For this purpose, an outlet pipe 62 is provided tangentially, the inlet of which is constituted by a horizontal slot, the height of which is adjusted to control the exit of the scrap material, for example. It is partially covered by a plate member 64 that is slidably mounted for the purpose of doing so. It is possible to connect the outlet pipe 62 to a recirculation device in a known manner.

The rotor member 48 may take any of a variety of shapes to perform the whipping function, as shown, for example, in FIG. In FIG.
Two horizontal arm members 48' are mounted, and the horizontal arm members 48' are interconnected at their outer ends by two slanted connecting members 49. In this example the axes 4 should be spaced apart from each other to allow rotation in a constant direction. Connecting member 4 if possible
9 preferably has a sharpened forward edge, but the rear edge may be flat or may be provided with a flap member to impose hydrodynamic turbulence to facilitate fluidization of the fiber. .

The screening device 12 does not necessarily include three bottom screen walls 14 and screen wall sections 16 of the same mesh.
There is no need to prepare. For example, by careful selection of the type of screening device, a sheet of loose fibers consisting of two outer layers of one type of fiber and an intermediate layer of another type can be formed on the wire mesh. The different types of fibers are differentiated by the type of screen wall section selected. Tests have shown that longer fiber lengths than are normally processed by the dispensing apparatus of the present invention can be processed.

In the modified embodiment shown in FIG. 6, the rotary agitator is mounted for rotation about a horizontal axis. Numbers used to designate parts in the previous figures are also used in FIG. 6 to designate corresponding equipment. The dispensing container 1 has a modified bottom wall section with a screen 15 having a straight U-shaped cross section at the bottom. Two horizontal shafts 5 are arranged parallel to this bottom wall portion, and a pair of whip members or rotor members 148 arranged to be rotated by motor drive devices 38 and 40 are mounted on each shaft 5. has been done.

The screen 15 has a bottom wall portion (i.e., a portion corresponding to the screen bottom wall 14 in the embodiment of FIG. 2) and a pair of side wall portions (i.e., a portion corresponding to the screen wall portion 16 in the embodiment of FIG. 2). As described above, it has a U-shaped cross section as a whole. Further, the rotor member 148 protrudes in the radial direction of the horizontal shaft 5, so that when the rotor member 148 rotates together with the horizontal shaft 5, the tip of the rotor member 148 is in a plane perpendicular to the surface of the side wall portion of the screen 15. Move in a circular motion,
passing through an area adjacent to the side wall portion. Some of the rotor members, namely those rounded at the tips and designated by the reference numeral 51 in FIG. This causes a general movement of the fiber material along the section and in the axial direction of the horizontal axis 5. 6th
As indicated by the arrows in the figure, the direction of movement of the fiber material along one sidewall portion of the screen 15 is opposite to the direction of movement of the fiber material along the other sidewall portion of the screen 15. The rotor member thus serves the purpose of both whipping the material and moving the material around within the dispensing container.

An important feature of the dispensing device shown in FIGS. 1-4 is that, when rotated, the tip of rotor member 48
The rotor member 48 is arranged to rotate in a circular manner in a plane that is not parallel to the screen wall portion 16 , and when the rotor member 48 rotates, the tip of the rotor member 48 touches the screen wall portion 1 .
6. That is, the tip of the rotor member 48 moves in a circular trajectory, but the plane in which the circle is drawn is a horizontal plane parallel to the bottom screen wall 14, as is clear from FIG. Since the rotor member 48 has an inclined surface extending in the vertical direction, the tip of the rotor member 48 rotates in a circle within a plane that is not parallel to the screen wall portion 16 or within a plane that intersects the screen wall portion 16. and,
During the rotation, the tip of the rotor member 48 passes close to the screen wall portion 16. Such a configuration allows the area of effectively fluidized fibers to be directed by centrifugal force toward the screen wall portion 16, thereby orienting the fibers to facilitate passage through the screen wall portion 16. It is possible to do so.

The distribution device shown in FIG. 6 differs from the devices shown in FIGS. 1 to 4 in the arrangement of the rotor member 148 and the like.
However, in the distribution device shown in FIG. 6 as well, since the rotor members 148, 51 protrude in the radial direction of the horizontal shaft 5 extending along the side wall portion of the screen 15, the rotor members 148, 51 are not easily rotated when the rotor members rotate. The tip is configured to rotate in a circular manner in a plane that is not parallel to the side wall portion of the screen 15 (that is, in a plane perpendicular to the side wall portion). Further, during the rotation, the tip of the rotor member passes a position close to the side wall portion of the screen 15. Therefore, in the dispensing device of FIG. 6, the effectively fluidized portion of the fiber is directed by centrifugal force toward the side wall portion of the screen 15, and the fiber can easily pass through the side wall portion of the screen 15. You can point yourself in the direction of gaining.

The distribution apparatus of FIGS. 1-4 also directs the overall flow of loose material along the inner surface of the screen wall section 16 to facilitate uniformity of the amount of fibers passing through the screen wall section 16. It is becoming more and more important. It has already been mentioned that the distribution device of FIG. 6 is likewise adapted to produce a general flow of loose material along the inner surface of the side wall portion of the screen 15. Preferably, but not necessarily, the dispensing vessel 1 is provided with excess air if the fibers are being fed through the fishtail-shaped fiber dispensing inlet 58 with conveying air in excess of the amount of air being evacuated via the evacuation device 26. It is preferably covered with a lid portion (not shown) of screen material that allows the fibers to escape but retains the fibers within the container.

The amount of fiber within the dispensing vessel 1 is controlled by controlling the rate of entry in response to the rate of exit so as to maintain a constant profile of the fibers along the screen wall portion 16. Surprisingly, however, experiments have shown that it is possible to produce sheets with evenly distributed fibers without maintaining such a constant profile. In fact, even if the fiber is clumsily fed into the dispensing container 1 until the dispensing container 1 is actually empty, the money net 20
It is possible to obtain an even layer of fibers on top. This is a significant advantage of the present invention.

The rotor member may be of any suitable design, such as a wire member, and may be suitably arranged for rotation such that its distal end portion is repeatedly moved toward and away from the screen wall portion with which it cooperates. It's okay. The sliding gate 32 for controlling the suction area may be subdivided into sections as shown in dotted lines in FIG. The sections are thus individually actuated to adjust the shape of the suction area 28 to control possible thickness variations across the sheet of open fiber. That is, if the layer of fiber is to be provided with a thicker or thinner longitudinal zone, the portion or portions of the sliding gate 32 below the zone are positioned to respectively increase or decrease the suction area of interest. If, over a long period of continuous operation, the screen wall section becomes plugged with fibers or foreign matter, thereby creating a zone of reduced sheet thickness, the individual sections of the sliding gate 32 are moved to counteract this. be able to. This can also be controlled by automatic equipment.
This method of controlling the thickness of the sheet formed by suction is not only suitable for modifying the cross-sectional uniformity of the sheet, but is also advantageously used as a device for controlling the thickness of the sheet in general. be able to.

The inclined screen wall portion 16 is provided with a number of free openings where the centrifugal force of the rotor member acts, thus facilitating the penetration of fibers through the free openings. A slight drawback that arises from this is that some of the fibers are guided directly towards the inner surface of the outer wall plate 50 and accumulate on this inner surface, creating the risk that at some point suddenly a mass of fibers will fall. However, this risk is overcome by air flow through the skivesing channel 52. Another solution to this problem is to use in place of the outer wall plate 50 a horizontal roller that covers part of its surface to cover the space of triangular cross section between the screen wall section 16 and the wire mesh 20. In this way, fibers deposited on the roller surface can be continuously removed and the need for scavenging channels 52 and air gates 56 can be eliminated.

As can be seen from the foregoing, the dispensing method and dispensing apparatus of the present invention maintains the fiber or particulate material in a fluidized state within the dispensing vessel and creates a circular flow of said material along the walls of the screen device. , moreover, a velocity component is imparted to the flow that partially directs it toward the wall. This configuration significantly improves the ability to distribute the material onto the carrier web, the distribution capacity, and the uniformity of the distribution, and even if the holes in the wall become clogged with material. The fluidization and circulating flow of the material has the effect of removing clogged material.
