Since the sheet material tobacco immediately after unpacking is in the form of a compressed laminate, the feeder is equipped with a rake roller that unravels the sheet material tobacco in the compressed and laminated state, and directs the unraveled sheet material tobacco to the next process. Can be supplied. Therefore, most of the sheet raw material tobacco that has passed through the feeder is
Generally, it becomes a single leaf regenerated tobacco raw material and is transported to the next step.

[0003]

However, if the compressed laminate of tobacco sheet material is strong, unraveling in the feeder becomes insufficient, and the tobacco material is conveyed to the next step as a consolidated mass. is there. This consolidation lump causes a raw material to stay in the middle of the transportation, and causes a raw material to be clogged in a relatively narrow portion of the transportation path. Furthermore, when the recycled tobacco raw material and another tobacco raw material are blended, the consolidated agglomerate hinders the uniform blending of the tobacco raw material and causes a reduction in the blending accuracy.

[0004] The present invention has been made based on the above-described circumstances, and its object is to provide a simple configuration.
It is an object of the present invention to provide a sheet material tobacco feeder capable of supplying a stable sheet material tobacco.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a feeder for sheet raw material tobacco is provided with a feeder 2 for recycled tobacco raw material, and the feeder 2 has a conveyor housing 4. A horizontal conveyor 6 is arranged in the conveyor housing 4, and the conveyor housing 4 has a receiving port 8 above the start end of the horizontal conveyor 6. Therefore, the sheet raw material tobacco, that is, the compressed laminate S thereof can be supplied from the receiving port 8 into the conveyor housing 4. Here, the compressed laminate S is obtained by stacking individual sheet raw material tobacco (for example, a square of 5 × 5 cm) in a container (not shown) of a container, a box, and a pallet, and thereafter compressing the same. After being unpacked from the container, the compressed laminate S is dropped into the conveyor housing 4 from the receiving port 8 and received on the horizontal conveyor 6, and is conveyed by the horizontal conveyor 6 toward its end.

[0010] Further, a scraping conveyor 10 is arranged in the conveyor housing 4. The scraping conveyor 10 extends obliquely upward from the vicinity of the end of the horizontal conveyor 6, and has a number of scraping pins 12 protruding from its transport surface. Compressed laminate S reaching the end of horizontal conveyor 6
Is scraped by the scraping pins 12 as the scraping conveyor 10 travels, and the recycled tobacco raw material T obtained by the scraping is conveyed upward from the lower end of the scraping conveyor 10.

Further, a rake roller 14 is rotatably disposed directly above the upper end of the scraping conveyor 10, and the rake roller 10 has a number of rake pins protruding from the outer peripheral surface of the roller. Raised conveyor 10
The recycled tobacco material T that has reached the upper end of the
Is further disentangled by the rake pin and sent out from the upper end of the scraping conveyor 10. The conveyor housing 4 includes a hopper 16 connected to the upper end of the scraping conveyor 10, and the recycled tobacco material T sent from the scraping conveyor 10 is dropped into the hopper 16.

A flow controller 18 is provided at the lower end opening of the hopper 16.
The flow control unit 18 is provided with a horizontal conveyor 22 in the housing 20. Therefore, the recycled tobacco raw material T dropped into the hopper 16 is fed from the lower end opening of the hopper 16 to the horizontal conveyor 2.
2 will be received. Further, a drop shooter 24 is connected to the housing 20, and a lower end opening of the drop shooter 24 is formed as a drop port 26.
When the horizontal conveyor 22 runs, the recycled tobacco raw material T on the horizontal conveyor 22 is transported toward the drop shooter 24 and then dropped downward from the drop shooter 24. Therefore, the flow control unit 18 controls the traveling speed of the horizontal conveyor 24 so that the drop shooter 24
, The amount of the recycled tobacco raw material T dropped from the container can be controlled.

A belt conveyor 28 is disposed below the drop shooter 24 as a transport path, and the belt conveyor 28 extends horizontally to a blending machine (not shown). It should be noted that tobacco materials other than recycled tobacco materials are supplied to the blending machine. A sieve conveyor 30 is horizontally disposed between the belt conveyor 28 and the drop chute 24, and the sieve conveyor 30 is parallel to the belt conveyor 28 from the drop port 26 of the drop chute 24 over a predetermined length. Extends to.

The sieve conveyor 30 is composed of a roller conveyor in which a number of rollers 32 are arranged at predetermined intervals, and the upper surface thereof is configured as a sieve surface. That is, the opening of the sieve surface is defined by the interval between the adjacent rollers 32. For example, the diameter of the roller 32 is 61 mm,
The gap between the two is set to about 59 mm. Each roller 3
2, two ends are rotatably supported by left and right frames 34, and a sprocket 36 is attached to one end thereof as shown in FIG. The sprockets 36 are engaged with an endless chain 38, which extends between the driving sprocket and the driven sprocket. FIG. 2 shows only the driving sprocket 40, and the driving sprocket 40 is connected to an output shaft of a motor (not shown). When the drive sprocket 40 is rotated by the motor, the chain 38 travels in one direction, and with this travel, the rollers 32 rotate in the same direction, that is, in a clockwise direction as viewed in FIG. The rotation speed of the motor,
That is, the rotation speed of each roller 32 can be arbitrarily changed.

Further, as shown in FIG. 3, a large number of projections 42 are provided on the outer peripheral surface of each roller 32, and these projections 42 are arranged in a staggered arrangement between adjacent rollers 32. I have. In the example shown in FIG. 3, each protrusion 42 is obtained by winding a pair of arc-shaped plate members whose both ends are folded around the outer peripheral surface of the roller 32, and connecting the folded portions at both ends to each other. I have. Also,
When the wire is wound around the outer peripheral surface of the roller 32, a part of the wire can be projected as the projection 42. In addition,
When the distance between the rollers 32 is 59 mm, the protrusion length of the protrusion 42 is set to about 11 mm.

A brush roller 44 is disposed immediately above the end of the sieve conveyor 30, and the brush roller 44 is rotated in a direction opposite to that of the roller 32. FIG.
As shown in FIG.
And a large number of bristle portions 48 planted on the outer peripheral surface of the roller 46. Each bristle portion 48 is obtained by arranging a bristle bundle 50 in two rows in a spiral shape. Here, as apparent from FIG. 1, the brush roller 44 can rotate while its bristle portion 48 is in contact with the roller 32 of the sieve conveyor 30. In addition, as shown in FIG.
At the end of 0, a collection container 52 is arranged.

When the recycled tobacco raw material T is dropped from the above-mentioned outlet 26 of the hopper 16, the recycled tobacco raw material T is once received by the sieve conveyor 30. Here, even if the recycled tobacco raw material T is unraveled to the extent that it has fluidity like a single-sheet flow, or if it is a lump, the consolidated lump can pass between the rollers 32 of the sieve conveyor 30. If the size is large, the recycled tobacco raw material T falls through the sieve conveyor 30 and is received on the belt conveyor 28. Thereafter, the recycled tobacco raw material T is conveyed by a belt conveyor 28 toward a blending machine.

However, if the compacted mass of the recycled tobacco raw material T is larger than the opening width between the rollers 32 and the mesh of the sieve surface formed by the interval between the rollers 32 and the projections 42, the compacted mass will be removed from the sieve conveyor. 30 cannot pass through, and is left on this sieve conveyor 30. Thereafter, the large consolidation mass is transferred on the sieve conveyor 30 toward the brush roller 44 with the rotation of the roller 32.

When the large compacted mass reaches the brush roller 44, the rotating brush roller 44 beats the compacted mass at its bristle portion 48 to break the compacted mass. At this time, if the crushed compacted mass becomes small enough to pass between the rollers 32, the compacted mass also passes through the sieve conveyor 30 and falls onto the belt conveyor 28, and is received by the belt conveyor 44. It is. On the other hand, the compacted lump that has not passed through the brush roller 44 and is not sufficiently crushed by the brush roller 44 is discharged from the end of the sieve conveyor 30 to the collection container 52, and the compacted lump is regenerated tobacco material T on the belt conveyor 28. It does not get mixed in.

Therefore, there is no solidified mass larger than the allowable limit in the recycled tobacco material T supplied on the belt conveyor 28, and the recycled tobacco material T on the belt conveyor 28 is stable toward the bread machine. Transported. As a result, during the transportation, not only can the retention and clogging of the recycled tobacco raw material T caused by the consolidation lump be prevented, but also the raw material can be blended well in the blending machine and the blending accuracy can be improved. Can be done.

Since each of the rollers 32 of the sieve conveyor 30 is provided with the above-mentioned projections 42, the solidified mass of the recycled tobacco material T remaining on the sieve conveyor 30 is sent out by being hooked on the projections 42 of the rollers 32. As a result, it is reliably conveyed toward the brush roller 44. That is, the compacted lump does not stay on the sieve conveyor 30. The present invention is not limited to the embodiments described above, and various modifications are possible. For example, the sieve conveyor 30 is not limited to a roller conveyor, and a belt conveyor having a belt surface in a mesh structure can be used.

[0022]

As described above, according to the sheet raw material tobacco feeder of the first aspect, since the sieve conveyor is disposed between the discharge port of the supply device and the transport path, the recycled tobacco raw material is discharged. Even if a large consolidation mass exists, the consolidation mass remains on the sieve conveyor and is not supplied on the transport path. Therefore, since only the recycled tobacco material that has passed through the sieve conveyor is received on the transport path, when the recycled tobacco material that is transported on the transport path is transported to the blending machine in the next process, the condensed agglomerate Therefore, the raw material can be stably conveyed toward the blending machine without causing stagnation or clogging of the raw material, and the mixing accuracy can be improved in the blending machine.

According to the feeder of the second aspect, since the sieve conveyor is obtained from the roller conveyor, the gap between the rollers can be used as individual eyes of the sieve surface, and the sieve conveyor can be simplified. Can be configured. According to the feeder of claim 3, since a plurality of protrusions are provided on each roller of the roller conveyor, even if a compacted lump of recycled tobacco material remains on the roller conveyor, the compacted lump is formed on the roller protrusion. It can be sent out by hooking, and the consolidated mass does not stay on the roller conveyor.

According to the feeder of the fourth aspect, since the brush roller is further provided immediately above the sieve conveyor, it is possible to crush the solidified mass transferred and fed on the sieve conveyor by the brush roller.
