Definitions
- the invention relates to a device for waste disposal on the card, in particular the disposal of waste excreted on the licker-in and / or the cleaner shaft.
- the tasks of a card are the disintegration to single fiber, the removal of impurities, the removal of dust, the dissolving of nits and a band to form.
- the elimination of impurities happens especially in the area of the licker-in. Only a small part of the impurities goes along with the lid outlet or precipitates in other places.
- the degree of cleaning of the modern card is very high at 80 - 95%. Due to the aggressive dissolution of the flakes at the feed trough by the licker-in, a lot of dirt is released. Thus, the departure at the licker has a lot of dirt (70-90%).
- a cleaning point can be provided on the opening roller in the hopper.
- the excretion is also selective at this cleaning site and may contain a large amount of "dark" finish, depending on the setting.
- the single excretion point of the card - both the licker-in and the drum and lid - are combined in a card today in a collecting line and transported to a central waste container.
- the suction capacity is limited, partly by the high costs and partly by the negative effect, which has too much suction on the Aus colgungung ⁇ gseffizienz the individual excretory.
- EP 750 059 introduces a system wherein the drop of the licker-in falls into a separate container and is removed therefrom only intermittently. By short-term throttling the suction at the remaining location and the container to suck in this period, greater influence on the remaining locations can be minimized and the waste can, if necessary, disposed of by means of a flap via a separate path or collected.
- a prerequisite of this method is that the precipitates are directed down the licker-in, the precipitates located above the roller need suction to carry away the precipitated particles before they are pulled back onto the roller.
- the outlet device consists of a container with at least two chambers, separated by an air-permeable wall, z. As a filter cloth, a perforated plate or screen plate.
- the chamber that effectively collects the waste has at least one entrance connected to a waste disposal site or the waste disposal sites so that the waste can be collected separately from the other waste disposal sites and an exit for the further transport of the collected material.
- the other Chamber has only one opening, which is connected to a vacuum source. This source may be, for example, the central aspiration channel used for the remaining excretory sites.
- all the exits and entrances are provided with means for opening and closing, so that the process can be controlled.
- the inlet connected to the waste site, and the outlet communicating with a source of negative pressure will be open, thereby sucking the waste discharged and keeping it in the collection chamber by means of the air-permeable wall.
- the extracted air leaves the housing through the air-permeable wall via the outlet in the second chamber.
- the inlet and air-permeable wall are arranged such that the air flow can sweep the air-permeable wall surface and thereby cleans the air-permeable wall.
- the air-permeable wall is arranged opposite the entrance, which is connected to the vacuum source, in such a way that optimum use is made of the surface of the air-permeable wall. If, in particular, the distance between the inlet and outlet is chosen as far apart as possible, the air-permeable wall can be used over the entire surface.
- the input is arranged such that the force of gravity may additionally be responsible for the deposition of the contaminant material, but without affecting the effect of the air-permeable wall.
- input and output are arranged such that the material air flow can deposit the longest path over the air-permeable wall, so that the excretory function of this wall is optimally utilized.
- the output connected to a vacuum source, is then intermittently closed and the output connected to the discharge channel, which is also connected to a vacuum source, is opened. Possibly also an entrance, connected with purging air, is opened. Although one for the purge air one 2005/000733
- Compressed air source can provide, it is cheaper to arrange only one opening in connection with the environment. Since the chamber is always under a negative pressure, either from the entrance connected to a vacuum source itself or from the discharge channel, which is also connected to a vacuum source, air is sucked through an opening from the environment. This sucked air flow is sufficient to convey the accumulated material in the transport channel.
- the advantage of this method is that the opening associated with the waste site does not have to be closed. The excretion site is thereby permanently sucked off. The effects on the discharge site by interruptions in the suction or by fluctuations in the suction power are thereby eliminated.
- the collected material is removed from the capture chamber and forwarded via a separate channel, either to a reusable waste collection site where all carded waste of this type is collected or returned to be reintroduced at a convenient location in the process.
- a separate air flow is passed as scavenging air over the bottom of the collecting chamber, so that the removal of heavier parts is guaranteed and the process can be shortened in time.
- the material outlet and possibly the scavenging air opening are closed again and the input, connected to the excretion point, and the outlet, connected to a vacuum source, are opened again.
- the bottom of the collection container is designed so that the dirt particles are collected in a groove, wherein the shape of the groove is adapted to the openings for the purging air and the removal.
- the intermittent extraction of waste from the outgoing device has a particular advantage in larger systems consisting of several cards, each having a departure device. If each outlet device is permanently evacuated separately, then the total suction is higher and the separate disposal is thus more expensive. With an intermittent suction, the H2005 / 000733
- Suction power is sufficient for only one or some of the cards and can be constructed inexpensively.
- the outgoing device can also be designed so that several precipitates are collected separately.
- a separate intake of the cleaner shaft outlet and licker-in can be realized by a three-chamber outlet device, wherein the middle chamber is separated from the two remaining chambers by means of air-permeable walls.
- the middle chamber is connected to a vacuum source and the outer chamber is either for recording from the licker-in or from
- Cleaner shaft outlet provided. The easiest way to emptying the two chambers is at the same time, but via separate channels.
- FIG. 1 Schematic representation of a carding machine.
- FIG. 2. Schematic representation of the outgoing device according to the invention from above FIG. 2a and from the side FIG. 2b.
- Figure 1 shows a Wanderdeckelkarde 1, z.
- Example the Rieter card C60 with a working width of 1.5 meters, with a cleaner shaft 9. fiber flakes are transported through transport channels (not shown) through the various Putzereireamen and finally fed into the cleaner shaft of the card.
- the cleaner shaft consists of an upper shaft portion 10 and a lower shaft portion 13. Between the two shaft parts is a dissolving or opening roller, which is fed by means of a feed device 11. On the opener roller cleaning elements 12 may be arranged, which for the
- the cleaner shaft then passes the fiber flakes to the card as cotton wool.
- the feed device 7 feeds the fiber flakes to the lickerins 6.
- the lickerins open the fiber flakes and remove some of the dirt particles.
- Vorreisserwalze passes the fibers to the card drum 2.
- the Kardentrommei 2 cooperates with the covers 4 and parallelized while the fibers even further.
- the lids are cleaned by a lid cleaning 5. After the fibers have sometimes performed several rounds on the card drum, they are removed from the doffer roller 3 of the card drum, fed to the nip roller 8 and finally stored as a card sliver in a can in a pot (not shown).
- the excretory points are normally connected to the machine exhaust (25, Figure 2).
- FIG. 2a shows a side view
- FIG. 2b shows a view from above. Waste disposal and card or cleaning shaft are not drawn in relation to each other.
- the waste device 16 is provided with two chambers 22, 23 which are separated by an inclined air-permeable wall 21.
- This air-permeable wall can z. As a filter, be curious about a frame. ,
- the air-permeable wall has as large a surface as possible, the air can optimally use this surface and the dirt particles do not hinder the suction processes.
- the air-permeable wall is therefore arranged substantially vertically, so that no waste can settle on the wall.
- the air-permeable wall By placing the air-permeable wall not quite straight in the container but at a slight angle, the possibility of particle settling can be further reduced and the filtering surface remains optimized.
- the input 17 is connected, for example, to a precipitation point 24 in the card. These usually run as a channel over the working width of the card, as shown in Figure 2b can be seen.
- the inlet is arranged in such a way that gravity can also be responsible for the separation of the dirt particles, and that the sedimented particles do not revolve again.
- the second chamber 22 is connected to the central suction via output 20.
- the channel connections can be formed with separation points, whereby a simple removal of the device is ensured.
- the device can additionally run on wheels or on rails, so that the removal is simplified.
- a possibility can also be provided at the collecting chambers of the waste device for manual sampling, so that the waste composition can be assessed.
