Definitions
- the invention relates to a screen cleaner for plansifters with brush or knob-like cleaning heads.
- Such screen cleaners are placed in the screen frames of plan sifters, so that it is with the shaking movement of the sieve under the sieve covering move along and with their cleaning heads with the screen covering get in touch to clean them.
- the cleaning heads are not always up in contact with the fabric, but the cleaning effect mainly comes from the fact that the cleaning heads blows exercise against the fabric. This is achieved, for example, by that the screen cleaner with one foot on a parallel under the Screen covering arranged grid supports and thereby during its movement is vibrated via the corrugated grid.
- This known screen cleaner has the advantage that it has a low overall height of the sieve frame and with its cantilevered arms well into the Corners of the sieve frame can penetrate, so that the sieve covering also in the corner areas is cleaned well.
- the screen cleaner hits the edge of the screen frame, the free ones come Ends of two arms in contact with the edge of the sieve frame, while the third arm points to the center of the sieve. This has the consequence that the middle area of the sieve statistically more often from the cleaning heads is painted over as the border areas. This can lead to a uneven cleaning effect and increased wear of the Screen covering in the middle of the screen.
- the object of the invention is to provide a screen cleaner with which can achieve a more uniform cleaning of the fabric.
- This object is achieved in that the predominant Part of the cleaning heads is arranged essentially in a row and that a not or at least less dense with cleaning heads equipped spacers on one side from the row of Cleaning heads protrudes.
- the screen cleaner according to the invention hits the edge of the screen frame, it can be aligned so that the row of cleaning heads approximates runs parallel to the edge of the sieve frame. This way, in A relatively large area of the screen covering from the cleaning heads near the edge painted over while the spacer protruding inwards is less or not at all effective for cleaning. This way the statistical Medium achieved a more uniform cleaning of the screen covering and excessive wear of the screen covering in the area of the middle of the screen avoided.
- the spacer is preferably not equipped with cleaning heads and T-shaped with respect to the row of cleaning heads, and one Foot with which the sieve cleaner is supported on the smooth sieve bottom and which can also serve as a floor scraper, is under the spacer trained that he touches the sieve bottom at least two points.
- the cleaning effect will in this case not achieved by blows against the fabric, but rather that the cleaning heads cover the screen paint over. This eliminates blows against the fabric more than weighed that all cleaning heads are always effective cleaning are.
- Another advantage of this configuration is that that the cleaning heads are worn more evenly.
- the cleaning heads are preferably flexible against the Prestressed fabric so that possible dimensional tolerances in the distance between the sieve bottom and the sieve covering, for example as a result a slight curvature of the sieve bottom, not to jam the Sieve cleaner.
- the resilient bias can, for example by making the foot in its entirety opposite the row the cleaning heads is offset so that the one carrying the cleaning heads Part of the screen cleaner can dodge down.
- the flexible prestressing can also be achieved by means of elastic elements can be achieved, for example, through self-elastic training of the cantilevered arms that carry the cleaning heads or through one in the Foot integrated spring.
- a plan sifter equipped with screen cleaners according to the invention is the subject of claim 9.
- the sieve frames of such a plan sifter have in usually an almost square plan.
- a special one Uniform cleaning effect can be achieved if the length of the screen cleaner, measured from the row of cleaning heads to the free one End of the spacer, approximately half the edge length of the Sieve frame is.
- the screen cleaner 10 shown in Figures 1 to 3 has one in plan almost T-shaped body made of rubber-elastic material.
- This Body 12 forms two cantilevered arms 14, essentially on one Line are aligned and several are arranged in a row at the top Wear cleaning heads 16.
- the cleaning heads 16 can by knobs formed in one piece with the body or alternatively through tufts of bristles inserted into the body 12 are formed.
- the body 12 also forms a spacer 18 which is T-shaped to the Row of cleaning heads 16 arranged and opposite the cantilevered Poor 14 is slightly down.
- stiffening ribs 20 which are located at one end of the Connect spacer 18. The spacer points at the opposite end 18 an upstanding projection 22, the upper end, however is lower than the upper ends of the cleaning heads 16.
- cam 24 has one circular floor plan and is near the end of the Spacer 18 facing arms 14 during the cams 26 has an elongated plan and in the axial direction over the opposite End of the spacer 18 protrudes.
- Figures 4 and 5 show a modified Embodiment in which the arms 14 are connected in a straight line are and carry a continuous straight row of cleaning heads 16.
- the screen cleaner according to FIGS. 4 and 5 has the same structure as the screen cleaner according to Figures 1 to 3.
- FIGS. 4 and 5 also show a sieve frame 28 of a plan sifter.
- This sieve frame has a smooth bottom 30 and is through four walls 32, 34 limited.
- the screen frame 28 has a screen covering 36, which is arranged at a distance parallel to the floor 30.
- the wall 34 of the sieve frame forms an ejection slot with the bottom 30 38 for sieve diarrhea.
- the screen cleaner 10 is supported with its aligned on a straight line Cam 24, 26 on the smooth bottom 30 of the screen frame and is in the height so adjusted on the sieve frame that all cleaning heads 16 rest on the underside of the screen covering 36, as in FIG. 5 can be seen. Since the cams 24, 26 with the bottom 30 a line of contact define that is perpendicular to the row of cleaning heads 16, the screen cleaner 10 itself could tip over this line of contact. However, this is due to the installation of the cleaning heads 16 on the screen covering prevented. The cams 24 therefore slide with their flat underside over the surface of the floor 30 and can thus as a floor scraper Act. The cam 26 is also dimensioned in height so that it can also enter the output slot 38, as shown in Figure 5 is.
- the screen cleaner can Tilt cam 24. However, this is usually prevented by the fact that the center of gravity S of the screen cleaner is somewhat in relation to the cam 24 Direction on the cam 26 is offset. If the screen cleaner is in Exceptional cases, for example in the event of violent vibrations, but once should tilt, the swivel range is limited by the fact that the projection 22 based on the fabric. To tip the sieve cleaner 10 it can still happen if the distance between the bottom 30 and the screen covering 36 by warping or arching the Soil 30 has changed. In this case, the tiltable support prevents the screen cleaner jams between the floor and the screen covering. This can also be achieved by a certain elastic compliance of the arms 14 contribute.
- FIG. 6 shows a variant in which the cam 24 extends over a spring 40 supported on the body 12 of the screen cleaner.
- the elastic Biasing with which the cleaning heads 16 against the screen covering Press 36 set very precisely.
- the screen frame 28 has an approximately square plan with a Edge length a.
- the length L of the screen cleaner 10 measured from the row the cleaning heads 16 to the free end of the spacer 18 about a / 2.
- the screen frame 28 is shaken offset so that the screen cleaner 10 erratic movements on the floor 30 executes.
- the cleaning heads 16 can the left half of the fabric Clean to the edge, but you can use the right half of the fabric do not reach, because then the spacer 18 on the wall 34th of the sieve frame. If the screen cleaner has the opposite orientation only the right half of the screen covering can getting cleaned. Since the length L of the screen cleaner is approximately half that Edge length of the sieve frame, there is between the two areas the screen covering, which is cleaned at different orientations can be neither a large gap nor a significant one Overlap.
