Size sorting machine with adjustable profile rollers for round and bulbous products

j The innovation concerns constructive solutions, which in principle are a well-known Improve the quality of the sorting system.

■ Protected constructive solutions:

- 1. Adjustment of sorting rollers

[! ■ -2. Cleaning of sorting rollers

£ ■ - 3. Increasing speeds of the sorting rollers

f -4. Adjustable inclination of the sorting level

To 1. "Adjustment of sorting rollers"

With sorting machines that work according to the profile roller principle, is special the quick and even adjustment of the rollers is important. The distances between the rollers must remain the same over the entire area of use. Conventional systems can only be used to a limited extent here.

The innovation concerns a constructive solution with a lifting system. - Please refer j Figure 1:

Sorting rolls 1, 1 '., I "are mounted mutually displaceable uniform adjustment is k with adjusting lever 2, 2', 2 ^'reaches the levers are designed with two arms, the one end of the lever engages the roller and the other in the adjusting rod.. 3. The adjusting rod is actuated by means of a threaded rod 4 and handwheel 5. Uniform adjustment k is achieved by means of a pivot point arrangement A, B, C, which is at distances a, b, c from the roller plane.

To 2. "Cleaning of sorting rollers"

! The cleaning device of sorting rollers is problematic in that

Ί it is stressed differently on the one hand by the goods to be sorted, Uf> d on the other

, on the other hand, requires a stronger drive of the rollers and thus a

ί favors mechanical parts. A periodic one is therefore optimal

Cleaning of individual rollers as required.

The innovation concerns such a construction. - See Figure 2; Cleaning rake 1 is adapted in the profile of the sorting roller 2 and is laterally parallel to the rollers 3, tipping forces are controlled by roller guides 4 added. Adjustment of the cleaning rake from roller to roller for the purpose of cleaning is carried out with a hand crank or a motorized drive via a toothed drive achieved. The drive consists e.g. of a rack 6 and a gear attached to the drive shaft 7. When moving the These are cleaning rakes under the rotating sorting rollers cleaned one by one. The cleaning effect occurs in both Directions.

To 3. "Increasing speeds of the sorting rollers"

With the profiled roller sorting principle, all rollers rotate in the same direction. See figure 3:

The items to be sorted 1 lying on the rollers get an opposite one due to friction Rotary movement, which increases the sorting performance, but because of the different tuber shapes, creates a "clamping effect" of individual tubers between the Rolling can lead.

The innovation is that the drive of the rollers is selected according to a translation principle, according to which each subsequent roller - in the conveying direction seen - turns faster. As a result, the "ejection effect" is greater than that "Clamping effect" of the goods to be sorted. Gentle treatment of the tubers is thus guaranteed.

Transmission ratio i between the rollers can remain the same, but must have a value below 1.

To 4. "Adjustable inclination of the sorting level"

Depending on the goods and the quantity to be sorted, it is necessary to close the sorting level tend.

The innovation solves the problem by suspending the sorting device in a rocker-like manner. - See Figure 4:

The sorting device 1 is suspended on one side in the pivot point 2. The inclination can be adjusted using the threaded spindle 3 and handwheel with threaded nut 4.

Claims (4)

Protection claims 1. Figure sizing machine with adjustable profile rollers for round and bulbous products, characterized that the levers made of flat steel (2.2; 2 ") in the pivot points A, B, C on the side walls the machine are stored. They grip on one side via slot-like shaped guides the bolts of the adjusting rod (3) and on the other side in the axis extensions of the sorting roller (l, 1; i "). 2. Figure size sorting machine according to claim 1, characterized in that that she has a cleaning rake. The cleaning rake is attached under the sorting rollers (2) and held in driving angles (4) on both sides. The guide rollers (3) on the left ensure tipping stability and are attached to the right of the rake. Two gears (7) attached to the rack shaft engage in the Racks (6). A side crank aient to move. 3. Figure size sorting machine according to claim 1, characterized in that that each subsequent sorting roller - seen in the sorting direction - rotates faster (Rig. 3). This is achieved with sprockets (Zl) and (Z2) by means of a gear ratio Z2 / Zl 1. 4. Figure size sorting machine according to claim 1, characterized in that that the sorting unit is rotatably mounted on the inlet side (2). On the front of the holding frame there are threaded spindles (3) on both sides, as well as a handwheel (4) with spindle nuts. it Uli
