The present invention relates to a roller sorter driven by a chain having a pair of adjusting levers in more detail.

A casing 10; A rotating shaft portion 20 configured to rotate while being fixedly coupled to the casing; A pair of chain parts 30 which are guided by the rotating shaft part 20 and run in endless tracks; The chain portion 30 is characterized in that each of which is provided with a plurality of a pair of gap adjusting lever 660,

A sorting part 40 formed of sorting rollers 41 coupled to each hinge point of the gap adjusting lever 660;

A pressing part (50) for pressing the pair of gap adjusting levers (660) to adjust the gap between the sorting rollers (41);

It is characterized by consisting of the adjusting unit 60 for adjusting the height of the pressing unit 50 while being disposed on both end sides of the pressing unit 50.

The above configuration will be described in detail with reference to Figs.

First, referring to FIG. 1, the roller selector including the above-described components may include a separate supply part 70 and an outlet part 80.

In addition, the roller sorter, the structure of the casing, the method of driving the chain is already known, and the detailed description thereof will be omitted.

In addition, it will be described with respect to the remarkably improved differentiation in response to US Patent No. 06182832 (hereinafter referred to as "background technology") that is the background technology of the present invention.

2, the structure of a chain is demonstrated first.

Generally the chain is;

The inner link 1 having two holes and the outer link 2 having two holes on the outer side of the inner link 1 face each other in pairs, and the inner link 1 and the outer side face each other. Links 2 are connected in a zigzag connection.

In addition, all of the pair of inner links 1 are fixedly coupled by two inner link fixing pipes 4, and the outer pipes of the inner link fixing pipes 4 are provided with rotary pipes 5, respectively.

And all the pair of outer link (2) is fixed by the link connecting pin (3) while receiving the pair of inner link (1) fixedly coupled by two inner link fixing pipe (4) inside. Is coupled, this link connecting pin (3) is to be inserted into the inner link fixing pipe (4).

At this time, an important point of the present invention is the tolerance between the chain components.

The chain needs to be sturdy because it is pulled by the force of a powerful motor while it is connected by the coupling between the links.

Accordingly, the pair of inner links 1 and the inner link fixing pipes 4 are integrally fixed as an interference fit tolerance, and the pair of outer links 2 also have the link connecting pin 3. And integrally fixed together as an interference fit tolerance.

In this case, the fixed coupling expresses the complete body as if it were welded. That is, the pair of inner links 1 and the pair of outer links 2 become an integral structure that cannot be moved.

However, the inner link fixing pipe 4 is coupled to the link connecting pin 3 in the inner link fixing pipe 4 in a loose fitting tolerance, and the outer link of the inner link fixing pipe 4. The rotary pipes 5 are usually joined together in a very loose fit tolerance of up to about 1 mm.

Background art in this state is to provide a gap adjusting lever 66 (US Patent: Adjustlever) in order to narrow the gap between the sorting rollers 41 by pressing the chain has many problems.

When the gap adjustment lever 66 exerts a force of "P" on the bearing plate with a bearing plate 8 provided above the gap adjustment lever 66, the sorting roller 41 is on the line "O" of the rail surface. In the state of being positioned, the center point A1 or A2 of the sorting roller 41 is a hinge point, and the “B” point, which is an intermediate point between A1 and A2, is pressed, and as a result, the interval between the sorting rollers 41 is constant. It affects to be narrowed.

4 illustrates that as the height of H decreases to H1 and H2, the interval W between the sorting rollers 41 is narrowed like W1 and W2.

By the way, the background technology here is that the spacing of W is not exactly proportional as the height of H is lowered.

This arrangement of the adjusting lever 66 in the background is as follows.

First, the chain link 76 is provided instead of the outer link 2 and the spacing control lever 66 is coupled to the main shaft pin hole 72 (Attachiment) located above the chain link 76 as a hinge point. However, the outer link spacing members 7 are inserted between the chain link 76 and the spacing lever 66 and the low arm 69 of the spacing lever 66 moves the rotary pipe 5. Will be pressed.

Here, a loose fitting tolerance is generated primarily between the gap control lever 66 and the main shaft pin hole 72, and the link connecting pin 3 and the inner link fixing pipe at the point “B” are secondary. 4) The loose fit tolerances formed between the three parts are generated, and the third loose fit tolerances formed between the inner link fixing pipe 4 and the rotary pipes 5 are generated and are affected by the accumulated tolerances. The spacing W between the rollers 41 is such that an exact proportion to the height of H cannot be guaranteed.

Furthermore, in the background, only one gap adjusting lever 66 exists between the pair of chain links 76 (at the center), and the bearing with the pressing plate 8 corresponding to the pressing force " P " ) Is a cantilever-shaped unstable structure that is displaced to one side from the center of the chain and has an unbalanced structure without force symmetry.

In addition, the action point for pressing the "B" point when the pressing force "P" is applied is not the "A" point, which is the center point of the sorting roller 41, but the spindle pin hole 72 which is a position spaced a certain distance from the "A" point. Therefore, the cumulative error in manufacturing and assembling can be said to be larger.

On the contrary, the chain coupling technique according to the present invention will be described with reference to FIG.

In the chain coupling technique according to the present invention, the main shaft pin hole 72 and the outer link spacing member 7 are omitted in the background, and there are no cumulative tolerances due to their coupling.

On the other hand, a pair of the control lever 660 instead of one of the control lever 66 is configured and such a structure is to be a preferred structure for achieving improved durability and improved symmetry of the force.

The hinge point in the chain coupling technique according to the present invention is not the spindle pin hole 72 but the point “A” which is the center point of the sorting roller 41.

In addition, the spacing lever 660 is not configured between the pair of chain links 76 as the spacing lever 66 in the background, but a pair of spacing lever 660 is a pair The gap adjusting lever 660 at the same time will be a pair of outer link (2) itself.

That is, the pair is a pair of the space control lever 660 and the pair of space control lever 660, which is fixedly coupled by the link connecting pin (3) to form a body, the pair Another pair of gap adjustment lever corresponding links 661 to be pushed when the pressing force “P” acts on the gap adjustment lever 660 of the linking pins 3 is fixedly arranged as an integral type in connection with the link connecting pins 3. As a result, the outer link 2 presses another outer link 2 so that the gap between the sorting rollers 41 is narrowed.

At this time, the center of the hole for fixedly coupling the link connecting pin (3) on one side of the pair of adjusting lever 660 coincides with the center point of the sorting roller 41 and the sorting rollers 41 are rails When the "B" point is pressed while the state "O" is placed on the surface, the interval W of the sorting rollers 41 is narrowed as a result.

Here, the spacing control lever corresponding link 661 does not cause interference even when the spacing control lever 660 is pressed and the spacing control lever 660 rotates the center point of the sorting roller 41 as a hinge point. It is characterized in that the arc 662 is provided to prevent.

Therefore, there is a tolerance, and the pair of gap adjustment levers 660 that are fixedly coupled in one piece is not integrally coupled by assembly in which tolerances are accumulated. 661), and there is no tolerance between the components of the chain and no cumulative tolerance, which makes H and W the right proportional structure.

As a result, the intervals W, W1 and W2 between the sorting rollers 41, which are the life of the sorting machine, can be very accurate.

When the tolerance is described in detail in the above description,

In the background art, the tolerance due to the loose fitting produced primarily between the gap control lever 66 and the spindle pin hole 72 is about -0.1 mm, and secondly, the link connecting pin 3 and the inner link are fixed. The tolerance due to the loose fit formed between the pipes 4 is about 0.1 mm to 0.3 mm, and the tolerance due to the very loose fit formed between the inner link fixing pipe 4 and the rotary pipe 5 in the third order is 0.8mm ~ 1mm or so, the sum of the accumulated tolerance is up to 1.4mm,

The chain coupling technique according to the present invention has a sum of tolerances of 0 mm, and this difference is very important as it enables accurate maintenance and control of W, which is the interval between the sorting rollers 41, which is the most important requirement as a sorting machine.

In addition, the chain coupling technology according to the present invention is not only easy to manufacture due to the simple configuration, but also greatly improves mechanical stability and durability, and the ripple effect in the industrial field is expected to be great.

FIG. 7 shows the configuration in the case where W, which is the distance between the sorting rollers 41, should be very wide.

5 is a roller sorting machine driven by a chain having a pair of gap adjusting levers according to the present invention, wherein the sorting roller 41 is connected to the chain part 30 and the pressing part 50. Explain.

The adjustment lever shaft 662 is fixedly engaged inwardly, that is, in the sorting roller direction, at the “A” point of the gap control lever 660, which is a hinge point or action point for pressing the “B” point when the pressing force “P” is applied. do.

On the other hand, both ends of the sorting roller 41 is provided with a sorting roller connecting workpiece 42, and the sorting roller bearing 43 is provided inside the sorting roller connecting workpiece 42, the sorting roller bearing 43 and the The control lever shaft 662 is engaged in conjunction with the snap ring (stop ring) 44 or the like. And the outer ring of the sorting roller connection workpiece 42 may be provided with a rail groove 45 for allowing the sorting roller 41 to travel the correct track.

In general, however, the sorting roller 41 and the sorting roller connecting workpiece 42 are forcibly press-fitted to maintain a tight fitting tolerance for coupling or are provided with a hole in the outer ring surface of the sorting roller 41 for the sorting roller. It is a situation that the connection of the workpiece 42 and the bolt fastening, etc. This configuration is difficult to assemble and there is a possibility of disassembly and disassembly at any time.

On the contrary, the assembly technique according to the present invention has a hole in the inner surface of the sorting roller connecting workpiece 42, and passes through the workpiece connecting member 46 provided with a threaded bolt or a screw at both ends through the hole, and then unwinding. By fixing the lock nut 47, it will be equipped with a desirable structure for implementing a reliable assembly that is easy to ensure easy assembly and durability.

In the present invention, the sorting roller 41 is illustrated as a pipe, and the sorting roller connecting workpiece 42 is connected to each other at both ends of the pipe in connection with each other, but the surface of the sorting roller 41 may have various configurations. Can be.

That is, as shown in FIGS. 8 to 10, one or more semi-circles or elliptic curved portions 400 may be provided on the surface, and as shown in FIG. 11, when the curved portions 400 face each other, a circular space portion ( 401 may be generated and the spherical shaped article may be rotated and moved through the space, and may be sorted. In particular, the curved portion in which an ellipse-shaped abalone (success and chip) has a certain thickness rotates and moves. After being seated in the space 401 between the 400, the lengthwise direction of the ellipse becomes a desirable structure to be sorted and aligned toward the upper and lower surfaces of the sorting roller 41 (upright). will be.

The curved portion 400 of the sorting roller 41 may be empty as shown in FIG. 8, may be in a full state as shown in FIG. 9, and as shown in FIG. 10. 41) may form a body in one piece with the sorting roller connecting workpiece (42).

Both ends of the sorting roller 41 are provided with chain parts 30, respectively, and an upper part of the chain part 30 is provided with a pressing part 50.

Now, the pressing unit 50 will be described with reference to FIG. 6.

The pressing part 50 is manufactured as a plate-shaped metal material to minimize bending and maintain straightness, and uses a cutting method such as cutting by waterjet or laser cutting to minimize deformation by heat during cutting for manufacturing. The third reinforcement having a thickness that is easy to attach the primary reinforcing member 51, the upper and lower portions are bent, the secondary reinforcing member, the upper and lower portions are bent, and the wear-resistant member 54 is bent. The member and wear-resistant member insertion plate 53 is fastened by bolts to be integrally coupled.

The wear member having a c-shaped cross section that is easily inserted into the tertiary reinforcing member and wear-resistant member insertion plate 53 under the tertiary reinforcing member and wear-resistant member insertion plate 53 ( 54) is combined, this wear member 54 is a high-density polyethylene with a molecular weight average range of 5 million or more as a polymer material, non-toxic, and applies a material having excellent wear resistance, impact resistance, cold resistance, chemical resistance, and lubrication activity. .

On the other hand, both ends of the primary reinforcing member 51 is provided with an adjusting portion 60, respectively, the adjusting portion 60 is the upper and lower height in the casing while the screw portion 61 is fixedly coupled to the hinge 62. Nuts 63 are provided to enable adjustment, and the nuts 63 are disposed at upper and lower portions of the casing to be fixed in connection with the casing, and the hinge 62 is connected to the primary reinforcement by a coupling pin 64. The first reinforcing member 51 or the second reinforcing member is coupled to the member 51, and a plate (Scale) 65 made of metal is fixedly coupled to the casing, which is a fixed structure. It is possible to determine the height of the pressing portion 50 is maintained.

Compared with the configuration of the pressing part 50 and the adjusting part 60 according to the present invention, the pressing part and the adjusting part of the background art have a complicated structure and are difficult to realize the production.

First of all, the adjust rail 36 consists of a single unit with a thick and high cross section, so it has to be too high to maintain the truss shape and nevertheless the force "P" applied to the multiple adjust levers 66 Since it is easy to bend due to the reaction forces, tension bars (38) should be provided for each bracket (42) to correct them at any time, and the adjusting part for adjusting the height of the adjust rail (36) up and down Post (48), Crank (34), Shaft (52), many other components, and a Grar box system were required.

However, the pressing part 50 and the adjusting part 60 according to the present invention simplifies the parts and, while omitting, the durability is rather improved so that the structure is strong, and the weight is reduced, in particular, the tertiary reinforcing member and the wear-resistant member. Insertion plate 53 is a structure that can be disassembled and assembled from the pressing portion 50, so that when you want to change the rail guide surface 55 according to the sorted article can be replaced, the wear member made of synthetic resin material having abrasion resistance Denoted at 54 is a preferred configuration for quiet operation of the sorter.
