The rollers are supported in bearing blocks (30, 31) adjustable to vary the width of the gap. The rollers are driven from a common drive pulley (402) and respective roller pulleys (403, 404) and there is an arrangement for adjusting the tension in the pulley drive belt. Separating units may be stacked one above the other in a frame. <IMAGE>

Description

A Sorting Device for Shell Fishes This invention relates to a sorting device which can accurately sort out shell fishes, and can also adjust the sorting standards if necessary.
In a conventional sorting method for shell fishes, a sieve is usually used; every two persons are orgainzed as one team; usually, two such teams are required to provide three stages of sorting process; in other words, four persons are required at least to perform the sorting process; it is deemed a waste of manpower and time. Another sorting method for shell fishes is called a rotative cylinder type of sorting apparatus, which comprises four metal cylinders in different diameters, being assembled together like a nest of cylinder assembly. Each of the inner three cylinders has a plurality of round holes; the most inner (or first) cylinder has a plurality of largest holes, while the third cylinder has the smallest holes.When shell fishes (such as clams) are poured into the center of the cylinder assembly, the larger shell fishes will flow out of the sloping cylinder assembly, while the smaller shell fishes would flow through the round holes to flow into the second cylinder; finally, the shell fishes will be sorted into four grades. However, since the round holes on the cylinders have been set in different and fixed sizes, such a sorting apparatus is unable to meet the variation of sorting standards in different supply seasons; furthermore, the shell fishes are subject to being caught in the round holes during sorting operation, and some of them are subject to being broken upon falling from upper part of the cylinder assembly.It is deemed that such sorting apparatus is unable to provide an accurate sorting result because the sorting duration in a cylinder is too short to provide a better sorting result.
In view of the drawbacks of the prior art, the applicant has developed the present invention, of which the prime feature is to provide an adjustable sorting standard for shell fishes; the sorting standard can be varied by varying the space between two rollers through an adjustment assembly of bearing blocks so as to meet the market sorting requirement.
Another feature of the present invention is to provide a sorting device which can provide an accurate sorting requirement. According to the present invention, after a given quantity of shell fishes pass through the first set of rollers, they have to be moved together first before entering the second set of rollers; therefore, an accurate sorting result can be obtained; moreover, the present invention would not cause some of the shell fishes to be broken during sorting operation.
An embodiment of this invention is described by way of example with reference to the drawings, in which: FIG.1 is an exploded view of an embodiment-1 of a sorting unit according to the present invention.
FIG.2 is a perspective view of an adjustment assembly of a bearing block of the sorting unit of embodiment-1 according to the present invention.

Referring to FIG.1, a sorting unit 1 according to the present invention comprises two rollers 10 and 11, one material tank 20, two adjustment assemblies 30 and 31 for bearing blocks, and a belt-pulley driving assembly 40. Eoch of two rollers 10 and 11 is formed into a cylindrical shape; there are four two fixed axle ends 101, 102, 111 and 112 attached to the ends of the two rollers respectively to be mounted in bearings respectively. The material tank 20 is substantially a rectangular container with an opening 201 on the top thereof, an outlet 202 on the left end thereof, and two slots 203 on both sides of the outlet 202 respectively. The bottom 204 of the material tank 20 is formed into a taper shape with an outlet 2.05 to facilitate the shell fishes to flow out through the outlet 202.The sorting unit further includes two sets of opposite adjustment assemblies 30 and 31 of bearing blocks being the same in structure; therefore, only one of the adjustment assemblies is described in detail by referring to FIG.2, in which the adjustment assembly 30 of the bearing block includes two bearing blocks 301; each of the bearing blocks has a round hole 3011 for mounting a bearing 302 therein. Both sides of the bearing block have two round holes 3012 respectively to facilitate two screws 303 to pass through two slots 3041 on a base frame 304, and to pass through two round holes 3051 on a sliding plate 305 so as to fix the bearing blocks on the base frame 304 with Nuts 306 respectively. One end of the sliding plate 305 has a bolt hole 3052.Both ends of the base frame are mounted with two end plates 307 respectively each having a round hole 3071; an adjusting screw 308 passes through the round hole 3071, a lock ring 309, and a bolt hole 3052 of the sliding plate 305; the lock ring 309 is mounted in a groove 3081 on the adjusting screw 308. When the adjusting screw 308 is rotated, the position of the sliding plate 305 and the bearing block 301 can be adjusted to right left along the base frame 304 as shown with arrows, and therefore the space between the rollers 10 and 11 can be adjusted. As shown in FIG.1, the right end of the material tank 20 is mounted with a belt-pulley driving assembly 40, which includes a motor 401, a driving pulley 402, two driven pulleys 403 and 404, and idle pulley 405, a belt 406, and an adjusting screw 407 for the idle pulley. The motor 401 is to be fixedly mounted on a frame 408. The driving pulley 402 is mounted on the motor shaft; the two driven pulleys pulleys 403 and 404 are mounted on two fixed axle ends 102 and 112 of the two rollers 10 and 11 respectively. The idle pulley 405 as shown in FIG.3 is mounted on the sliding plate 411 by means of a screw 409 to insert through a round hole 4051 of the idle pulley 405, a spacer 414, a slot 4081 of the frame 408, a round hole 4111 of the sliding plate 411,- and a nut 412. The sliding plate 411 has another bolt hole 4112, through which an adjusting screw 407 passes through a round hole 4082 of the frame 408, and the colt hole 4112 of the sliding plate 411; the adjusting screw 407 has a groove 4071, around which a lock ring 413 is mounted so as to maintain the adjusting screw 407 in place.Whenever the adjusting screw 407 is rotated, the sliding plate 411 and the idle pulley 405 will be moved up or down so as to adjust the tension of the belt 406.
Referring to FIG.1 and 4, a perspective view of a sorting unit according to the present invention is shown; in the aforesaid views, the adjustment assemblies 30 and 31 are fixedly mounted on both ends of the material tank 20 by means of two base frames 304 and 314 respectively; the fixed axle ends 101, 102, 111 and 112 of the two rollers 10 and 11 are fixedly mounted respectively on the bearings 302 and 312 on the bearing blocks 301 and 311 of the adjustment assemblies 30 and 31 of bearing blocks. Whenever the bearing blocks 301 and 311 are moved, the space between the two rollers 10 and 11 will be changed.The right end of the material tank 20 is furnished with a belt-pulley driving assembly 40, in which a driving pulley 402 can be driven to rotate counter-clockwise by means of the motor 401, and then the driven wheel 403 will be driven to rotate counter-clockwise, while the driven pulley 404 will be driven to rotate clockwise.
FIG.5 and 6 illustrate respectively a perspective view and a disassembled view of the present invention, which comprises two sorting units 1 and 2. The two sorting units 1 and 2 are supported from their center portions respectively by means of two screws 50 and 51 and two nuts 531 and 541 so as to have the two sorting units fixedly mounted on two supporting plates 53 and 54 respectively. Both ends of the outer frame 52 are mounted with two hand wheels 55 and 56 respectively for angle adjustment of the material tanks 20 and 21 of the two sorting units 1 and 2; when one of the hand wheels 55 and 56 is turned, one of the all thread rods 57 and 58 will be moved up or down.One end of each of the all thread rods 57 and 58 has a rod end bearing ( not shown ) to be connected with one of the material tanks 20 and 21 so as to control one of the material tanks 20 and 21 to set at a given angle desired. When shell fishes or the like enter the space between the rollers 10 and 11 from the material inlet 64, the shell fishes will flow in the material tanks as a result of gravity thereof , the slanting material tank and the rolling rollers; the shell fishes will be sorted automatically in accordance with the space between the two rollers and their size. The shell fishes which are smaller in size than the space between the two rollers will fall below the rollers, while the shell fishes which are bigger in size than the space between the two rollers will move along the two rollers to flow out through the outlet 202 of the sorting unit 1.The small shell fishes which fall below the rollers 10 and 11 of the sorting unit 1 will flow out through the outlet 206 in the bottom 204 of the material tank, and the shell fishes will flow into the sorting unit 2, i.e., the small shell fishes will fall in the space between two rollers 12 and 13 for further sorting steps. The bottom of the outer frame 52 is mounted with fixing legs 59 and castors 60 to facilitate the present invention to set up and to move, if necessary.
The prime operation principle of the present invention is to utilize the smooth and slippery natures together with the rolling speed of the rollers, the sloping angle, the length of the rollers, the space between two rollers, and the diameter of rollers. Since the rollers can rotate, the shell fishes can slide and move between the two rollers. When the shell fishes slide between two rollers, the different sloping angles of the shell fishes would increase the gravity and moving speed, and the falling speed thereof,i.e., the sorting speed would be increased. The length of the rollers is in direct proportion to the precision of the sorting process, since the rollers are longer in length , the shell fishes would need a longer time to move thereon in series.The space between two rollers can be set to a given space by adjusting the adjustment assembly of the bearing block so as to sort out the shell fishes in size. The diameter of the roller is in direct proportion to the space between the rollers. The bigger the space is, the more quantity the shell fishes can be sorted up; in other words, a sorting device should be designed in accordance with the aforesaid five factors for better sorting result. The present invention after experiment on the prototype vevice has been proved to meet the aforesaid factors (or requirements), i.e., the length and the rotation speed of the rollers, the space between two rollers, the sloping engle and the diameter of the roller.According to the present invention, the sorting accuracy thereof can be over 84%, the sorting device according to the present invention can process 1600 Kgs of clams (about 120 thousands clams) per hour; the aforesaid quantity is almost equal to the quantity done by eight persons with the conventional sorting method, i.e..
the present invention can provide a large quantity of sorting process accurately.
After a given quantity of shell fishes, such as clams, are sorted through the sorting unit 1, there would be less 50% of the given quantity of middle sized and small sized shell fishes to be further sorted through the sorting unit 2; therefore, an additional sorting unit 1 should be installed in parallel with the first sorting unit 1 (as shown in fig.7). The shell fishes to be sorted will be poured into the material inlets 61 and 62, and then the shell fishes will flow out through the material outlet 63 in one stream before entering into the sorting unit 2; in other words, the sorting capacity of the sorting device will be increased by 50%.
Furthermore, a water stream 73 can be provided over and between the rollers 10 and 11 as shown in FIG.8 so as to facilitate the process of less weight shell fishes, such as clams or the like.
