    Disclosed is a method and apparatus for pressing and binding voluminous material into bales, in which material in the form of several layers is supplied through a closable opening into a pressing chamber where compression takes place of each supplied layer. Final pressing is carried out at high pressure after a desired number of layers have been supplied into the pressing chamber, whereafter the pressing effect is lowered to a substantially lower pressure, so that the material compressed into a bale is permitted to expand, and the bale thereafter is discharged from said pressing chamber through a closable opening and bound while said substantially lower pressure is being maintained.

    A device for packing a fibrous material includes a shaft 1 for loading a material, s of which there is a weighing mechanism 2 with a PLATE 3 and a flap 4; a plate made in the form of a comb 5, for compressing material in the shaft 1, in the side wall of which there is an outlet port 6. The device comprises a pre-pressing chamber 7 with a press plate 8 equipped with a vertical plate 9 for closing the window 6 and plate 10 with strips 11 to act on the material during its pre-pressing, powered by a hydraulic motor 12, a pusher 13, a hydraulic motor 14 for moving. a press plate 8, a horizontally mounted movable plate made in the form of a comb 15, similar in shape and purpose of the comb 5, a pressing chamber 16 with a press plate 17 set in motion by a hydraulic motor 18, and a fixture 19 to hold the compressed portions of material s compressed when the press plate 17 is lifted. Chambers 7 and 16 are separated from one another by a wall 20, the latter being rigidly connected to the plate 17 and moving together with it upwards, together with the chambers. In the device there is one more movable horizontal plane plate, made in the form of a comb 21, and equipped with a hydraulic motor 22 a pusher 23 with a plate-like horizontal element. On the piston moved by the press plate 17, there are elements interacting with limit switches 24 to 25.
    The press chamber 16 is formed, on two opposite walls 26, connected to the respective hydraulic motors 27, the pressure in which is regulated by valves 2B and can reach a maximum of 25 kg / cm.
    In the lower part of the chamber 16 there are two covers 29, which at the time of pressing the material form the wall of the chamber 16, and after the end of the pressing process. Are shifted outward and serve as a guideline
    transferring the compressed portion of the material through the lower window to the following operations - packaging and wrapping. To reduce the pressure of the wall 26 on the material bale, there is an additional valve 30. The bale travels in lateral pressure due to the action of the ejector 32 driven by the hydraulic motor 31.
    For packing and wrapping the bale, the device is equipped with a special mechanism in which there is a drum 33 with packaging material 34, rollers 35, a conveyor belt 36 and roller conveyors 37, the latter are installed at the lower window of the chamber 16.
    A knife 38 is provided to cut the packaging material, for example a polyethylene film.
    The shaft 1 has an exhaust box 19 with an outlet nozzle 40. By this, the upstream air flow is prevented in the shaft 1, which impedes the movement of the fibers falling into the shaft. The chamber of preliminary pressing is communicated with a box of 39 cherkez grooves, shaped by a rod 11.
    The upper wall of the box 39 is made of an air-permeable material. A fan is connected to the outlet 40. The latter creates a vacuum in the mine, which prevents the possibility of material leakage through the gaps of the mine. The privatera 16 communicates with the chamber 7 via the upper window 41.
    The device works in the following way.
    In the shaft 1 serves fibrous material. The latter is uniformly distributed over the cross section of the shaft. The material is collected and held by plate 3 associated with mechanism 2. As soon as the mass of the material portion reaches a predetermined value, the valve 4 is pushed into the shaft. Then plate 3 is pushed and the material drops from it, filling the lower part of the shaft.
    At this time, the portions of the material are held by the flap 4 (Fig. 5).
    After the delay time has elapsed, the comb 5 is pushed into the shaft through an opening in one of its walls. The plate 3 also slides in at the same time. Then the valve 4 is pushed out and the material falls onto the plate 3. The individual portions of the material, padakvdie, are pressed to the bottom of the shaft 5, which is pressed to the bottom of the upper edge of the outlet 6 at the same time. The latter, when the portions of the material are pressed in, is closed with a PLATE 9.,

    Claims (6)
    [1]
    Before the material is fed into the pre-pressing chamber 7, the press plate 8 of the latter is moved upwards and set so that. the bottom surface of the slats 11 is located at the same level with the upper edge of the window 6 (FIG. 9). Then, under the action of the pusher 13, portions of the material from the shaft 1 enters the chamber 7. At the same time, the plate-like element of the pusher blocks the shaft from the bottom (Fig. 10). The comb 15 is pushed out of the chamber 7, and the comb 5 (fig. 11 and 4) returns to its initial position. The fiber entered into the chamber 7 is compressed, after which the comb 15 enters the open slots formed by the strips 11 of the plate 10 (fig. 12). These operations are repeated until the desired amount of material is accumulated in chamber 7 - usually it comes in 4-5 portions. The compressed portion of chamber 7 enters the keiler 16. Before this, plate 17 is moved up to the level of the upper mass limit located in chamber 7. At the same time, wall 20 moves upwards (Fig. 13). As soon as the plate 17 reaches the top position, the comb 21 moves in the chamber 16 (Fig. 15). Then the pusher 23 comes into action, under the action of which the material from the chamber 21 enters the chamber 16. Under the plate 8, a horizontal element of the pusher 23 is installed, which, upon reaching the extreme lateral movement, returns the plate 8 to the upper position (Fig. 9), and the next portion of material enters the chamber 7 (Fig. 10) The comb 16, the retainer 19 extends from the chamber 16 and the press begins. As soon as the plate 17 passes a certain height mark, for example 850 mm, the pusher 23 returns to the extended position at another level, for example 700 mm, and the limit switch 24 is activated (Figures 18 and 19). After applying pressure to the fiber for a predetermined time, the plate returns to the upper level (850 mi) and remains in this position until the signal from the final switch 25 is obtained (Fig. 20 and 21). Usually, a bale is formed from three batches of material. When pressing the first portion, the plate 17 begins to rise after it is ready for delivery from the chamber 7 of the follower, a portion of the material. When pressing the second and third portions, the plate moves upward after the elements of the latch 19 enter into the chamber, preventing the expansion of the compressed portions. During the final pressing of all three portions, the pressure of the walls 26 is limited. After returning the plate 17 to a level of 850 mm in chamber 16, the KE-1-pans 29, window 41 is opened, the pressure of the side walls 26 decreases on the bale, and the ejector 32 is turned on. It is enough to move the walls 26 outward 40 mm when the side friction decreases to it was possible to move from the chamber 16 along the opened covers 29 to the roller conveyors 37. Here the bale is packed into a film, which is fed from the drum. After returning the ejector 32 to the initial position, the covers 29 also return to their original positions, closing the window 41, and the chamber 16 is ready for the next working cycle. The proposed device can produce bales of various sizes. Dimensions are preferable for textile fiber bales: length 1050 mm, width 550 mm and height 9001000 mm. The density of the material in the bale is 125-150 kg / m. The density of the material itself before the formation of a bale is 10 kg / m. The fibers can be of various materials, namely, viscose, perlon, etc., and have different thickness and length. The performance of the device is different. When working on viscose, it can be 80-100 tons per day. Claim 1.
