Description

  The present invention relates to a tobacco raw material sorting / exclusion system and a sorting / exclusion method thereof that sort and separate tobacco raw materials into non-defective products and defective products and eliminate defective products.

Generally, the tobacco raw material used for cigarette manufacture is obtained by cutting leaf tobacco, etc., and then dried to a predetermined moisture content, and further, a desired fragrance is added as necessary ( Patent Document 1).
Thereafter, the tobacco raw material is stored in the silo or directly supplied to the hoisting machine and used for cigarette manufacture.

WO 01/060185

  If the cutting of leaf tobacco or the like and the drying of the tobacco raw material are incomplete, the tobacco raw material does not all become a good product, and a defective product exists in the tobacco raw material. Defective products here include those that are larger than non-defective products and those that are entangled with tobacco raw materials, and such defective products are a major factor that deteriorates the quality of cigarettes.

In order to avoid such problems, it is desirable to select and separate defective products from the tobacco material and eliminate the defective products before the tobacco material is supplied to the silo or hoist.
For example, it is conceivable to supply a tobacco raw material to a sorting / separating device, sort the tobacco raw material into a non-defective product and a defective product by the sorting / separating device, and separate and eliminate only the defective product from the tobacco raw material.

  However, it is very difficult to completely sort a tobacco raw material into a non-defective product and a defective product using a single sorting / separating apparatus. For this reason, if the accuracy of screening defective products is increased, a large amount of non-defective products are inevitably mixed into the rejected defective products, and the yield of tobacco raw materials is deteriorated. On the other hand, if the defective product selection accuracy is lowered, it is not possible to avoid mixing defective products in the cigarette.

  For this reason, it is conceivable to improve the single sorting / excluding device to eliminate the above-mentioned trade-off relationship, but a long development period and a large investment are indispensable for improving the sorting / excluding device. On the other hand, even if an attempt is made to improve the sorting / exclusion device, an advantage that is commensurate with the development period and investment is not found, and in fact, the improvement of the single sorting / exclusion device has been abandoned.

  The present invention has been made on the basis of the above-mentioned circumstances, and its object is a simple configuration, and a tobacco material sorting / exclusion system capable of efficiently sorting and eliminating defective products in tobacco materials, and The purpose is to provide a screening / exclusion method.

The above-described object is achieved by the tobacco material sorting / exclusion system of the present invention. This system is provided between a sorting / separating device and a multi-stage sorting / separating device for sorting and separating tobacco materials into non-defective products and defective products. Is received as an intermediate stage, receives a defective product that has been sorted and separated by the sorting / separation device in the immediately preceding stage, performs a remanufacturing process to eliminate the defect, and remanufactures the defective product into a remanufactured product. And a remanufacturing device that supplies the raw material as a tobacco raw material to the sorting / separating device in the immediately subsequent stage, and the sorting / separating device in the final stage finally eliminates the defective product that has been sorted and separated.

  The present invention also provides a method for sorting / excluding tobacco raw materials, comprising a sorting / separating process and a remanufacturing process corresponding to the multi-stage sorting / separating apparatus and remanufacturing apparatus of the system.

  According to the sorting / exclusion system and method of the present invention, after sorting / separating tobacco raw materials, a defective product is subjected to remanufacturing processing, and the defective product is remanufactured into a remanufactured product. Good products will be included, and after that, by repeating the sorting and separation for the remanufactured product, the amount of defective products to be finally eliminated is reduced, and the yield of tobacco raw materials is improved.

  The sorting / exclusion system (method) according to the present invention has a simple configuration since a remanufacturing device (process) is simply provided between a plurality of sorting / separation devices (processes) having the same configuration. Sorting and exclusion can be performed efficiently.

It is the schematic which showed the flow of manufacture of the tobacco tobacco as a tobacco raw material. It is a schematic block diagram of a selection / exclusion system. It is a specific block diagram of the selection / exclusion system of one embodiment. It is a schematic block diagram of a wind-selection separation apparatus. It is a schematic block diagram of a reproduction apparatus. It is a perspective view of a basket.

Referring to FIG. 1, a basic flow of manufacturing a cigarette as a cigarette raw material is schematically shown, and the cigarette manufactured here is used for manufacturing a cigarette.
First, a leaf tobacco is prepared, and the leaf tobacco is cut into a tobacco of a predetermined size at the cutting stage 2, and then the tobacco is dried at the drying stage 4, so that the sorting / exclusion system 6 according to the present invention is used. Supplied.

The sorting / exclusion system 6 sorts and separates the cigarettes into good products (good products) and defective products (defective products), and transports only the good products to the silo 8 as the final stage, for example. The silo 8 stores non-defective items for a predetermined period.
Thereafter, the good product in the silo 8 is supplied to a hoisting machine, and is used for manufacturing cigarettes by the hoisting machine.

  Note that FIG. 1 does not show a scented stage for adding a fragrance to tobacco, but this scented stage is provided in the subsequent stage of the cutting stage 2, the drying stage 4, the sorting / exclusion system 6, and the silo 8. Can do. The non-defective product may be supplied directly from the sorting / exclusion system 6 to the hoisting machine for use in cigarette production.

  FIG. 2 shows the details of the sorting / exclusion system 6. In the case of this embodiment, the sorting / exclusion system 6 has two wind sorting / separating devices as a sorting / separating device, that is, primary and secondary wind sorting / separating devices 10, 12 and a remanufacturing device 14 arranged between these wind separation devices 10 and 12, which are more specifically shown in FIG.

As shown in FIG. 3, the primary wind separation / separation apparatus 10 includes a hollow sorting cylinder 16 that extends in the vertical direction.
As is clear from FIG. 4, an ascending air flow from the lower end opening 16 _L toward the upper end opening 16 _U flows in the sorting cylinder 16, while the lower end opening 16 _L and the upper end opening 16 are disposed on the outer peripheral surface of the sorting cylinder 16. _An introduction port 18 is provided between the _U and _U, and the dried tobacco is introduced into the sorting cylinder 16 through the introduction port 18.

The cigarettes introduced into the sorting cylinder 16 in this way are sorted into non-defective products and defective products by the rising airflow according to their weight. That is, the non-defective product is blown up by the ascending air current, rises in the sorting cylinder 16 together with the ascending air current, and is sent out from the upper end opening 16 _U of the sorting cylinder 16. In other words, the upper end opening 16 _U is a non-defective product sending port for sending good products. Thereafter, the non-defective product sent from the non-defective product delivery port is transferred to the silo 8 together with the air flow.

On the other hand, failure Shinakoku will drop through the screening cylinder 16 regardless of the upward current is sent from the lower end opening 16 _L. That is, the lower end opening _16L is a defective product delivery port. Such defective products include oversized and heavier than fine products, and entangled engraved cigarettes that are entangled with each other. On the other hand, entanglement is likely to occur due to the transport of tobacco in the drying stage.

The above-described primary wind separation / separation apparatus 10 sends, for example, about 10% of the introduced tobacco as a defective product from the defective product delivery port (lower end opening 16 _U ).

A charging conveyor 20 is disposed below the sorting cylinder 16 in the primary wind separation / separation apparatus 10, and the charging conveyor 20 extends obliquely upward toward the upper end of the reproduction apparatus 14, and the primary wind separation / separation apparatus 10 and the reproduction apparatus. 14 is connected. Therefore, the lower end opening 16 _L of the sorting cylinder 16, that is, the defective product engraved sent from the defective product delivery port is received by the input conveyor 20, and the direction of the arrow A in FIG. It is transferred to the remanufacturing device 14.

  The reproduction apparatus 14 includes a processing cylinder 22. The processing cylinder 22 of the present embodiment has a hollow prismatic shape extending vertically, and has a charging port 24 whose diameter is increased upward at the upper end. Therefore, the defective product transferred on the input conveyor 20 is input into the processing cylinder 22 through the input port 24.

  A remanufacturing unit 26 is arranged in the processing cylinder 22, and this remanufacturing unit 26 is shown in FIG. For example, the remanufacturing unit 26 includes a horizontal drive shaft 28, which can be rotated, for example, clockwise as viewed in FIG. A large number of bladed disks 30 are attached to the drive shaft 28, and these bladed disks 30 are arranged at predetermined intervals in the axial direction of the drive shaft 28.

Each bladed disk 30 has a plurality of rotary blades 32 on the outer periphery, and these rotary blades 32 are arranged at intervals in the circumferential direction of the bladed disk 30.
On the other hand, a large number of fixed blades 34 are fixed to the inner wall of the processing cylinder 22 along the drive shaft 28 and facing each other. These fixed blades 34 are arranged between the bladed disks 30 so as to sandwich the drive shaft 28 from both sides.

  The defective product engraved in the processing cylinder 22 falls toward the remanufacturing unit 26 and passes through the remanufacturing unit 26. At this time, the reproduction unit 26 performs a process for remanufacturing defective products. That is, the rotary blade 32 and the fixed blade 34 of the remanufacturing unit 26 cooperate with each other to re-engrave excessive engravings as a remanufacturing process, while releasing the entanglement and re-engrave the defective engravings. Remanufactured to (re-product). Therefore, the re-engravement includes a large amount of non-defective engravings by re-engraving defective engravings and releasing entanglement.

  Furthermore, in the case of this embodiment, the remanufacturing apparatus 14 further includes a basket 36 as a mesh member immediately below the remanufacturing unit 26, and the basket 36 has a semi-cylindrical shape that covers the remanufacturing unit 26 from below. For example, the basket 36 is made of punched metal and has a large number of uniformly distributed openings 38 that are smaller than the size of the defective product and larger than the re-work.

  Therefore, even if the defective product is to pass through the remanufacturing unit 26 without being subjected to re-cutting or entanglement, the defective product is captured in the basket 36 and temporarily stays on the basket 36. Thereafter, the defective product on the basket 36 is subjected to a remanufacturing process (re-engraved or entangled) by contact with the rotary blade 32, and passes through the opening 38 as a re-engraved process, whereby the defective product is efficiently reprocessed. be able to. Note that by changing the size of the opening 38, it is also possible to control the amount of non-defective items to be included during the re-engraving.

  As is clear from FIG. 3, the re-engraving is sent downward from the lower end opening of the processing cylinder 22, that is, from the re-engraving delivery port 40, and is received by the introduction conveyor 42. The introduction conveyor 42 extends obliquely upward from the lower side of the re-engravement sending port 40 toward the secondary wind separation / separation device 12, and transfers the re-engraving received in the direction of arrow B in FIG.

  The upper end of the introduction conveyor 42 is connected to the secondary wind separation / separation device 12 through, for example, an introduction chute 44, and the secondary wind separation / separation device 12 has the same structure as the primary wind separation / separation device 10 described above. That is, the secondary wind separating / separating device 12 also includes the vertical sorting cylinder 16, and the introduction chute 44 is connected to the introduction port 18 of the sorting cylinder 16.

Accordingly, the re-etching is introduced from the introduction conveyor 42 into the sorting cylinder 16 of the secondary wind separation / separation device 12 through the introduction chute 44 and the introduction port 18, and is sorted into good and inferior goods in the sorting cylinder 16. The non-defective product is sent from the upper end opening 16 _U (good product delivery port) of the sorting cylinder 16 toward the silo 8, while the defective product is sorted from the lower end opening 16 _L (exclusion port) of the sorting cylinder 16 as an exclusion time. Excluded outside the exclusion system 6 (see FIG. 4).

  As is clear from the above description, the secondary wind separation / separation device 12 performs the same function as the primary wind separation / separation device 10. This is only about 0.3% of the total amount of cigarettes introduced into the separator 10.

  Therefore, according to the sorting / exclusion system 6 and the sorting / exclusion method implemented in the system 6, the remanufacturing process (re-cutting) is performed between the front and rear wind separation processes that perform the same function.・ Easy to remove the entanglement), it is possible to efficiently select and eliminate the defective product in the cigarette and greatly improve the yield of the cigarette.

The present invention is not limited to the above-described embodiment, and various modifications are possible.
For example, in one embodiment, the wind selection separation process is performed twice, but the wind selection separation process may be performed three or more times. In this case, the wind selection separation process and the subsequent wind selection separation process may be performed. It goes without saying that the remanufacturing process is performed at each of the intervals.
Further, the specific structures of the wind separation / separation device and the remanufacturing device are not limited to the illustrated examples, and various modifications can be made as necessary.
