Description

Technical Field

[0001] This invention relates to the field of air loom technology, and more particularly to a jacquard air-jet loom. Background Technology

[0002] In the textile industry, jacquard air-jet looms are widely used in the production of high-end fabrics such as home textiles, clothing, and decorative fabrics because they combine the ability to weave complex patterns using jacquard technology with the high-speed and high-efficiency characteristics of air-jet weft insertion. Their core technology involves independently controlling the warp yarn rise and fall through the jacquard system to create complex sheds, which, in conjunction with high-speed airflow, completes the weft yarn introduction, achieving continuous production through warp and weft interlacing. Air-jet looms primarily use the jacquard head to independently control the raising and lowering of each or each group of warp yarns according to the pattern design, forming a dynamic shed that changes with the pattern for the weft yarn to pass through, providing the foundation for the formation of complex patterns. The main nozzle of the air-jet loom sprays high-pressure airflow, drawing the weft yarn out from one side of the loom. At the same time, auxiliary nozzles spray air along the weft yarn path, using the propulsion of the airflow to make the weft yarn pass through the shed at high speed, completing the introduction of the transverse yarn. The reed pushes the introduced weft yarn towards the weft, making the weft yarn and warp yarns interweave tightly, fixing the current interweaving point, and forming the fabric structure. The warp feed mechanism releases the warp yarn rhythmically and maintains stable tension, while the take-up mechanism simultaneously winds the woven fabric, ensuring that the jacquard opening, air-jet weft introduction, and beat-up actions are carried out cyclically, achieving continuous production.

[0003] However, the aforementioned air-jet looms still have limitations in practical use. While installing a jacquard loom head above the air-jet loom allows for the synchronous weaving of complex patterns during the weaving process through synchronized operation of the jacquard head and the air-jet loom, it also generates a large amount of lint. This lint mainly originates from the high-pressure airflow that carries and peels away loose fibers or short fibers on the surface of the warp and weft yarns during high-speed interlacing. The frequent raising and lowering of the warp yarns by the jacquard head further exacerbates fiber shedding. Due to the gap between the jacquard head and the flat loom, and the tendency of the high-speed airflow of the air-jet system to form vortices, the lint not only diffuses into the workshop environment but also adheres to precision components such as the needle bed, electromagnetic actuators, nozzles, and reeds of the jacquard head. This leads to problems such as jacquard needle jamming, nozzle blockage, and signal transmission failures, increasing equipment maintenance costs and downtime, while also affecting the surface smoothness of the fabric. Therefore, a jacquard air-jet loom needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides a jacquard air-jet loom to solve the problem that, although the aforementioned air-jet looms, after being equipped with jacquard heads, can simultaneously weave complex patterns, they generate a large amount of drifting fibers, polluting the environment, adhering to parts, and causing malfunctions.

[0006] The present invention adopts the following technical solution: a jacquard air-jet loom. It mainly includes a support frame with a through-slot for the yarn to pass through. A jacquard loom unit is mounted on the support frame, and an air-jet loom is positioned directly below the support frame. A dust removal assembly is located at the bottom of the support frame. The dust removal assembly includes two sets of mounting frames installed at the bottom of the support frame, with two sets of dust removal sections positioned between the two sets of mounting frames. The two sets of dust removal sections are arranged at opposite positions at one end of the mounting frames, forming a double-sided clamping coverage of the through-slot area. Each dust removal section is equipped with a drive unit for dynamically moving the dust removal section along the warp yarn running direction. A rotating part corresponding to the number of three dust suction groups is mounted on the dust removal section, allowing for flexible adjustment of the angle of the dust suction groups. A power unit is integrated into the side of the rotating part.

[0007] Furthermore, the dust removal components are symmetrically distributed on both sides of the penetration groove. Each dust removal unit includes a fixed seat installed on one side of the two sets of mounting brackets that are close to each other. A horizontally mounted lead screw is connected between the two sets of fixed seats by bearings. Guide rods are fixed at parallel positions on both sides of the lead screw between the two sets of fixed seats. The guide rods and the lead screw together form a main and two auxiliary transmission and guiding structure.

[0008] Furthermore, the drive unit includes a sliding seat threaded onto the external thread of the lead screw. The sliding seat has a threaded hole inside that matches the pitch of the lead screw. Sliding holes that match the diameter of the guide rod are machined on both sides of the sliding seat. A set of mounting brackets has a forward and reverse motor fixed on the outer wall. The output shaft of the forward and reverse motor is rigidly connected to one end of the lead screw via a coupling.

[0009] Furthermore, support seats are movably sleeved on the two sets of guide rods. Through holes with a diameter larger than that of the lead screw are machined on the support seats. A concave frame plate is connected between the support seats and the sliding seat. The concave frame plate serves as a bridge connecting the transmission component and the dust collection execution component.

[0010] Furthermore, the concave frame plate integrates a dust collection unit, which includes a rotating shaft connected to the concave frame plate at both ends by thrust ball bearings, and can rotate flexibly within the space defined by the frame plate.

[0011] Furthermore, each set of the vacuum assembly includes a fixed frame sleeved on the rotating shaft. A pipe clamp seat is fixed to the outer end face of the fixed frame. Two sets of U-shaped clamps are symmetrically arranged on the pipe clamp seat. The U-shaped clamps are fixedly connected to the pipe clamp seat. A vacuum tube is provided between the two sets of U-shaped clamps. The vacuum tube can also maintain a stable posture. One end of the vacuum tube is connected to a vacuum hood through a connecting pipe. The vacuum hood is designed with a grid plate with an inclined angle facing the side of the penetration groove.

[0012] Furthermore, the three sets of vacuum cleaners are interconnected by vacuum pipes to form a complete vacuum network. The vacuum pipes of adjacent sets of vacuum cleaners are sealed together by quick connectors. The end of the vacuum pipe closest to the right is connected to the air inlet of the external vacuum cleaner through a flange, forming a complete negative pressure channel from the vacuum hood to the external vacuum cleaner.

[0013] Furthermore, each set of rotating parts is supported by a fixed sleeve installed on the bottom surface of the inner wall of the concave frame plate. The fixed sleeve has a through hole larger than the diameter of the rotating shaft, so as to reserve sufficient space for the rotation of the rotating shaft.

[0014] Furthermore, a power unit is integrated on the side of the fixed sleeve. The power unit includes a fixed frame installed on the side of the fixed sleeve and tightly fitted onto the rotating shaft. The fixed frame is securely connected to the fixed sleeve and serves as a load-bearing structure for power transmission. A drive shaft is mounted on the fixed frame via bearings. One end of the drive shaft extends out of the fixed frame and is fixed with a gear. A rack adapted to mesh with the gear is installed on the bottom surface of the support frame. The rack is mounted on the bottom surface of the support frame via a frame body. A second bevel gear is installed at one end of the drive shaft that extends into the fixed frame. A first bevel gear meshing with the second bevel gear is installed on the rotating shaft. The fixed frame body of the dust removal group is movably fitted onto the rotating shaft, and a clearance is reserved between it and the bottom surface of the inner wall of the concave frame plate.

[0015] Furthermore, the bottom surface of the support frame is equipped with protective covers of the same number as the dust removal section, and the shape of the protective covers fully conforms to the structural contour of the dust removal section.

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: A jacquard air-jet loom features a dust-collecting assembly at the bottom of the support frame. Two sets of dust-collecting sections, supported by two sets of mounting frames, form a double-sided clamping cover over the penetration groove area. This comprehensively intercepts lint generated during high-speed weaving of warp and weft yarns and during the jacquard loom's pulling of the warp yarns, preventing lint from spreading through the connection gap between the jacquard loom and the air-jet loom, thus reducing pollution to the workshop environment. The drive unit on the dust-collecting section dynamically moves along the warp yarn running direction, achieving coverage of the lint-generating area and preventing lint from adhering to components such as the needle bed of the jacquard loom. Simultaneously... The rotating part on the dust removal unit, corresponding to the number of three dust suction groups, can flexibly adjust the angle of the dust suction groups under the drive of the power unit. This adapts to the dynamic distribution of lint caused by the vortex formed by the high-speed airflow of the jet system, improving the efficiency of lint capture, preventing lint from clogging the nozzles and reeds of the air-jet loom, ensuring the stability of jet weft insertion, reducing weaving defects caused by equipment failure, and effectively preventing lint from contaminating the fabric surface, thus improving the smoothness of the fabric. Ultimately, while ensuring that the jacquard unit and the air-jet loom can weave complex patterns, the reliability of equipment operation and the quality of fabric production are improved.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-4 As shown, this embodiment of the invention provides a jacquard air-jet loom, including a support frame 1, which serves as the basic load-bearing structure of the entire device, providing stable support for various functional components. A through-slot 11 is provided on the support frame 1 for the yarn to pass through, providing a channel for the orderly transmission of yarn within the device and ensuring that warp and weft yarns can participate in the weaving process according to a predetermined path. Simultaneously, a jacquard unit 2 is installed on the support frame 1. The jacquard unit 2 includes a jacquard head 21 fixedly mounted on the support frame 1 by four sets of support legs 22. The four sets of support legs 22 are evenly distributed, ensuring that the jacquard head 21 is stably suspended above the support frame 1. The jacquard head 21, as the core component for realizing the jacquard function, integrates a warp control mechanism, which can control the lifting and lowering movement of the warp yarns according to a preset pattern program, thereby constructing sheds of different shapes and laying the foundation for forming complex patterns.

[0022] Meanwhile, an air-jet loom 3 is positioned directly below the support frame 1. This loom 3 is a crucial component for completing air-jet weft insertion and fabric weaving, and it is equipped with an air-jet system, warp feeding mechanism, and take-up mechanism. During operation, the warp yarns are drawn from the upstream yarn trough and enter the jacquard head 21 through the penetration groove 11 on the support frame 1. The jacquard head 21, based on the pattern design, uses mechanical or electronic control methods (such as electromagnetic needle drive in electronic jacquard machines or pattern plate-bore drive in mechanical jacquard machines) to orderly raise and lower the warp yarns, forming a shed of a specific shape. At this time, the air-jet system of the air-jet loom 3 is activated, and the main nozzle generates a high-speed airflow that draws the weft yarns from the bobbin. Driven by the airflow, the weft yarns pass through the shed formed by the warp yarns in the jacquard head 21, completing the weft insertion action. During the weft insertion process, auxiliary nozzles can supplement the airflow in a timely manner according to the weft yarn's flight path, ensuring that the weft yarns reach the weft end stably and accurately.

[0023] The warp feeding mechanism continuously provides warp yarns with stable tension for the weaving process, while the take-up mechanism simultaneously winds the woven fabric into a roll. The warp and weft yarns interweave at the weft shed, and with the control of the warp yarns by the jacquard loom head 21, a fabric with complex patterns is gradually woven. Throughout the entire weaving cycle, the jacquard loom head 21 and various mechanisms of the air-jet loom 3 work in coordination. The frequency and timing of the warp shed changes controlled by the jacquard loom head 21 must be precisely matched with the weft insertion rhythm and warp feed and take-up speed of the air-jet loom 3 to ensure the continuity of fabric weaving and the accuracy of pattern formation, avoiding weft yarn breakage, pattern deformation, and other weaving defects. This enables the jacquard air-jet loom to efficiently and with high quality weave fabrics with complex patterns, solving problems such as poor coordination and unstable weaving quality that may exist in traditional jacquard air-jet looms, and improving the adaptability and reliability of the equipment in high-end fabric production scenarios.

[0024] To address the issue of fiber friction and tension that easily generates lint when warp yarns pass through the pass-through slot 11 during the actual operation of a jacquard air-jet loom, which, if not cleaned promptly, will adhere to the surface of precision components (such as the jacquard head 21 and the air-jet system), affecting weaving accuracy and equipment lifespan, the following measures are taken: Figures 2-5 As shown, a dust removal assembly 4 is provided at the bottom of the support frame 1 and around both sides of the penetration groove 11. The dust removal assembly 4 includes two sets of mounting brackets 42 that are fastened to the end face of the support frame 1 away from the jacquard machine unit 2 by bolts, and the dust removal assembly 4 is symmetrically distributed on both sides of the penetration groove 11. Two dust removal units are provided between the two sets of mounting brackets 42. The two sets of dust removal units are arranged at opposite positions at one end of the mounting brackets 42, forming a double-sided clamping coverage of the penetration groove 11 area. Each set of dust removal units includes a fixed seat 43 fixedly installed on the sides of the two sets of mounting brackets 42 close to each other, providing a reliable installation reference for the subsequent transmission structure. Between the two sets of fixed seats 43, a deep groove ball bearing (or a suitable high-precision bearing) is used to cooperate, and a lead screw 45 is horizontally mounted. The lead screw 45 serves as the transmission core, which can convert the rotational power of the motor into linear drive. At the same time, guide rods 44 are welded and fixed between the two sets of fixed seats 43 at parallel positions on both sides of the lead screw 45. The guide rods 44 and the lead screw 45 together form a main and two auxiliary transmission guide structure.

[0025] To drive the dust removal unit to move dynamically along the warp yarn running direction and track and clean up drifting lint, a drive unit is provided on the lead screw 45. This drive unit includes a sliding seat 46 threadedly connected to the external thread of the lead screw 45. A threaded hole matching the pitch of the lead screw 45 is formed inside the sliding seat 46, and sliding holes matching the diameter of the guide rod 44 are machined on both sides of the sliding seat 46, ensuring that the sliding seat 46 can perform linear reciprocating motion along the guide rod 44 without significant deflection during the movement. On the outer wall of one set of mounting brackets 42, a forward and reverse motor (not shown in the figure) is fixedly arranged via a motor mounting bracket. The output shaft of this forward and reverse motor is rigidly connected to one end of the lead screw 45 via a coupling. When the motor rotates forward or reverse, it can drive the lead screw 45 to rotate clockwise or counterclockwise, thereby causing the sliding seat 46 to reciprocate stably and controllably along the axis of the guide rod 44.

[0026] To further enhance structural stability and adapt to dust removal requirements under different working conditions, support seats 47 are movably sleeved on the two sets of guide rods 44. These support seats 47 have through holes with a diameter larger than that of the lead screw 45, allowing the lead screw 45 to move freely and avoiding motion interference. A concave frame plate 48 is bolted between the support seat 47 and the sliding seat 46. The concave frame plate 48 acts as a bridge connecting the transmission components and the dust collection actuator. It also synchronously drives the support seat 47 to slide along the guide rods 44 when the sliding seat 46 moves, ensuring the coordination of the entire transmission support system. This provides a stable and dynamically adjustable mounting surface for the dust collection unit.

[0027] The dust collection unit is integrated into the concave frame plate 48. The dust collection unit includes a rotating shaft 49 connected to the concave frame plate 48 at both ends via thrust ball bearings. This shaft can rotate flexibly within the space defined by the frame plate, adapting to the dynamic changes in the distribution of lint during warp movement and ensuring that the dust collection direction is always precisely aimed at the area where lint is concentrated. Three sets of dust collection units are arranged at equal intervals along the axial direction around the rotating shaft 49. Through the coordinated operation of multiple sets, the dust collection coverage is significantly expanded, ensuring that lint at different locations near the penetration groove 11 can be effectively adsorbed.

[0028] Each vacuum unit includes a fixed frame 416 sleeved on a rotating shaft 49. The outer end face of the fixed frame 416 is fixedly mounted with a pipe clamp seat 417 by bolts. The pipe clamp seat 417 serves as the intermediate hub for pipe fixing. Two sets of U-shaped clamps 418 are symmetrically arranged on it. The U-shaped clamps 418 are fixedly connected to the pipe clamp seat 417 by bolts, nuts and other fasteners. A vacuum pipe 419 is provided between the two sets of U-shaped clamps 418, so that even if the equipment vibrates during operation, the vacuum pipe 419 can maintain a stable posture. One end of the vacuum pipe 419 is connected to a vacuum hood 421 through a connecting pipe 420.

[0029] As the component that directly contacts the lint, the dust hood 421 has an inclined grid plate on the side facing the penetration groove 11. On the one hand, the grid plate can initially intercept larger debris (such as yarn breaks and clumps of fibers) to prevent them from entering the dust suction pipe 419 and causing blockage. On the other hand, the inclined plate can guide the airflow to carry the lint smoothly into the dust hood 421. With the help of the negative pressure suction of the dust suction system, the lint is drawn and collected, thereby effectively purifying the operating environment of the jacquard air-jet loom, reducing the pollution of the precision structure of the equipment by the lint, and ensuring the stability of the fabric weaving process and the quality of the finished product.

[0030] When the equipment is started, the forward and reverse motors drive the lead screw 45 to rotate, which in turn drives the sliding seat 46, the concave frame plate 48 and the dust collection unit to move back and forth along the warp yarn path. The rotating shaft 49 can adjust the angle of the dust collection hood 421 in real time according to the distribution of fluff. Multiple dust collection units work together to capture the fluff around the penetration groove 11 in an all-round and dynamic manner, forming an efficient loom cleaning and protection system.

[0031] It should be noted that, to achieve efficient vacuuming operations, the three vacuuming units are interconnected via vacuum hoses 419, forming a complete vacuuming network. Specifically, the vacuum hoses 419 of adjacent vacuuming units are sealed together using quick-connect fittings (such as clamp fittings or threaded fittings) to ensure smooth airflow within the pipes and prevent leaks that could reduce vacuuming efficiency. Here Figure 4 For example, the rightmost suction pipe 419 is connected to the air inlet of an external vacuuming device (such as an industrial vacuum cleaner or a central vacuum system) via a flange, forming a complete negative pressure channel from the suction hood 421 to the external vacuuming device. This connection method not only facilitates the installation and disassembly of the equipment but also allows for flexible adjustment of the number and layout of the suction units according to actual production needs. After the external vacuuming device is started, a negative pressure is created within the system, causing dust-laden air to pass sequentially through the suction hood 421, the connecting pipe 420, and the suction pipe 419, and is finally drawn into the external vacuuming device for filtration. This effectively removes fiber lint generated during the operation of the jacquard air-jet loom, ensuring a clean production environment and the normal operation of the equipment.

[0032] To further improve the suction performance of the three suction units and achieve precise capture of lint from different angles, such as Figures 4-7 As shown, rotating parts corresponding to the number of three dust collection units are installed on the concave frame plate 48. These rotating parts allow for flexible adjustment of the angle of the dust collection units to accommodate the dynamic distribution of lint generated by the warp yarn movement. Each rotating part is fixedly installed on the bottom surface of the inner wall of the concave frame plate 48 by a fixing sleeve 410 (see reference). Figure 5 The fixed sleeve 410 is provided with a through hole (not shown in the figure) larger than the diameter of the rotating shaft 49, which provides sufficient space for the rotation of the rotating shaft 49 and avoids structural interference.

[0033] A power unit is integrated on the side of the fixed sleeve 410 to provide rotational power to the rotating shaft 49. Specifically, the power unit includes a fixed frame 411 fixedly mounted on the side of the fixed sleeve 410 and tightly fitted onto the rotating shaft 49. The fixed frame 411 is securely connected to the fixed sleeve 410 via bolts, serving as a load-bearing structure for power transmission. A drive shaft 413 is mounted on the fixed frame 411 via bearings, with one end of the drive shaft 413 extending out of the fixed frame 411 and fixedly mounted with a gear 414. Simultaneously, a rack 415 adapted to mesh with the gear 414 is mounted on the bottom surface of the support frame 1 via bolts or other means, forming a stable meshing transmission track. When the concave frame plate 48 moves with the sliding seat 46, the gear part 414 rolls along the rack 415, driving the drive shaft 413 to rotate. A second bevel gear 422 is fixedly installed at one end of the drive shaft 413 that extends into the fixed frame 411, and a first bevel gear 412 that meshes with the second bevel gear 422 is fixedly installed on the rotating shaft 49. Through the meshing transmission of the bevel gears, the rotational motion of the drive shaft 413 is converted into the rotation of the rotating shaft 49. It should be noted that the fixed frame 416 of the dust removal group is movably sleeved on the rotating shaft 49, and a clearance is reserved between it and the bottom surface of the inner wall of the concave frame plate 48. The existence of this clearance allows the dust removal group to flexibly rotate around the rotating shaft 49 by a certain angle through the fixed frame 416, thereby adjusting the orientation of the dust suction hood 421 in real time according to the distribution of fluff, greatly improving the dust suction effect, ensuring that fluff in the warp yarn passage area is efficiently adsorbed, creating a cleaner operating environment for the jacquard air-jet loom, and ensuring the quality of fabric weaving.

[0034] In this application, to further improve the reliability and ease of maintenance of the jacquard air-jet loom, protective covers 41, the same number as the dust removal unit, are installed on the bottom surface of the support frame 1. The shape of the protective covers 41 is designed to fully fit the structural contour of the dust removal unit, ensuring both protective effect and without affecting the normal operation of the dust removal component 4. The protective covers 41 are tightly connected to the bottom surface of the support frame 1 by bolts, and a silicone sealing gasket is provided at the connection point to effectively prevent the intrusion of impurities such as fly waste and dust.

[0035] The specific protective functions of the protective cover 41 include: on the one hand, forming a fully enclosed protection for transmission components such as the lead screw 45 and guide rod 44 to prevent fiber lint from getting tangled and causing transmission jamming; on the other hand, providing dust protection for precision components such as motors and couplings to extend their service life.

[0036] Working Principle: Complex patterns are woven through the linkage of the jacquard loom 2 and the air-jet loom 3. When the equipment starts, the warp yarns are drawn from the upstream yarn creel and enter the jacquard head 21 through the penetration groove 11 of the support frame 1. The jacquard head 21 controls the raising and lowering of the warp yarns according to the preset pattern program through electromagnetic needles or the pattern plate-pattern tube system to form a specific shed. At the same time, the air jet system of the air-jet loom 3 is activated. The main nozzle generates a high-speed airflow to pull the weft yarns out of the bobbin, and the auxiliary nozzles supplement the airflow to ensure that the weft yarns pass through the shed along the predetermined path. The warp feed mechanism delivers the warp yarns with constant tension, and the take-up mechanism synchronously winds the fabric. The three work together to complete the warp and weft interlacing. During this process, the warp control timing of the jacquard head 21 must be precisely matched with the air jet weft insertion rhythm to avoid weft yarn breakage or pattern deviation. Through this coordinated operation, the equipment can achieve a high-speed weaving of 600-800 wefts per minute, while ensuring the clarity and consistency of complex patterns (such as flowers and geometric patterns).

[0037] The dust removal component 4 adopts a working mode that combines dynamic tracking and multi-angle dust collection. When the equipment is running, the forward and reverse motors drive the lead screw 45 to rotate, which drives the sliding seat 46 to move back and forth along the guide rod 44, so that the dust collection part integrated into the concave frame plate 48 covers the entire area of ​​the penetration groove 11, ensuring that the dust collection hood 421 is always aligned with the area where fluff is generated; Meanwhile, as the concave frame plate 48 moves along the guide rod 44 with the sliding seat 46, the gear part 414 fixed to the end of the drive shaft 413 continuously meshes with the rack 415, and the drive shaft 413 rotates synchronously with the gear part 414. The rotational motion of the drive shaft 413 is transmitted to the rotating shaft 49 through the bevel gear pair (first bevel gear 412 and second bevel gear 422), causing the rotating shaft 49 to rotate around its own axis. The rotation of the rotating shaft 49 directly drives the fixed frame 416 and the dust hood 421 to rotate synchronously. The swing trajectory of the dust hood 421 and the linear motion of the sliding seat 46 combine to form a compound motion path. By optimizing the length of the rack 415 and the diameter of the gear section 414, precise synchronization of the angle and position of the dust collection hood 421 is achieved. The rotating shafts 49 of the three dust collection groups rotate synchronously through the same transmission mechanism, but the initial installation angles of adjacent rotating shafts 49 are different. This allows the three dust collection hoods 421 to form a continuous dust collection area during the swinging process, generating a synergistic effect of strong central suction plus auxiliary airflow on both sides, effectively covering different positions in the warp yarn passage area and improving the overall dust collection efficiency. The three sets of suction pipes 419 are interconnected and connected to external vacuuming equipment, forming a negative pressure channel. When the dust-laden airflow passes through the grid plate of the suction hood 421, large particles of debris are intercepted, while fine lint enters the suction pipe 419 with the airflow and is eventually filtered and collected.
