 Background art

 For example, instant 麵 in a container is provided with seasoning ingredients such as leafy vegetables such as cabbage and pak choi and root vegetables such as carrots and potatoes and dried. These dried vegetable pieces are manufactured through a series of processes, including harvesting, washing, shredding, and drying the raw vegetables. Through this manufacturing process, granules such as sand or twigs, straw, hair, lint, etc. Sometimes, the final dried vegetable pieces are mixed or mixed with fibrous materials.

 However, food is not hygienic in the presence of such foreign substances, and it is necessary to remove these foreign substances in order to avoid complaints from consumers.

Therefore, conventionally, granular foreign substances such as sand were separated by using a mesh-shaped sieve capable of separating dried vegetable pieces and foreign substances, and dried vegetable pieces were spread to appropriate places for fibrous foreign substances. Inspection workers visually inspected and removed them. However, granular foreign substances such as sand can be easily separated by a sieve, but fibrous foreign substances such as hair are extremely thin and it is extremely difficult to remove them by visual inspection. There was a problem that manual work was extremely inefficient and productivity did not increase. Such problems are not limited to the above-mentioned dried vegetable pieces, but other dry food pieces such as seafood, food pieces such as beans and cereals, foodstuffs such as gums and candy, and any other substances that may contain foreign substances such as the above.

 Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

 (First Embodiment)

 FIG. 1 is a front view showing a mixed foreign matter removing device according to the present embodiment, and FIG. 2 is a perspective view showing a part thereof. As shown in FIG. 1, the removing device 1 includes a supply device 2 for supplying an object to be processed, and a first foreign matter holding device 10 and a second foreign matter holding device provided sequentially below the supply device 2. 25, a first foreign matter removing device 30 provided below each of the first foreign matter holding device 10 and the second foreign matter holding device 25. A second foreign matter removing device 35, a collection baguette 3 It consists of 4, 36, 40 and shoots 26, 27. Hereinafter, the details of these units will be described.

 The supply device 2 includes a known belt conveyor 3 and leveling means 4 provided above the end of the belt conveyor 3 in the conveying direction (the direction indicated by arrow A). A rotating shaft 5 provided along the width direction of the belt conveyor 3, a plurality of leveling arms 6 standing on the rotating shaft 5 along the axial direction of the rotating shaft 5, and rotating the rotating shaft 5 in the direction of the arrow. And a drive unit (not shown).

The first foreign matter holding device 10 is provided with a pair of a drive rotary shaft 11 and a driven rotary shaft 12 arranged side by side at appropriate intervals, and a pair of drive rotary shafts 11 arranged at appropriate intervals on the drive rotary shaft 11. A pair of driven sprockets 13, a pair of driven sprockets 14 arranged side by side on the driven rotating shaft 12 with appropriate intervals, a pair of driven sprockets 13 and a driven sprocket 2 and a pair of chains 15 wound around each of them, and a pair of chains 15 shown in FIG. A plurality of slat bars 17, a porous sheet 18 wound around the outer periphery of the slat bars 17 and also formed into an endless annular shape, and the drive rotation shaft 11 is rotated in the direction of arrow D. A drive unit (not shown) is provided. By driving the drive unit (not shown) to rotate the drive sprocket 13 in the direction indicated by the arrow D, as shown in FIG. The chain 15, the slat bar 17 and the porous sheet 18 are configured to sequentially circulate and rotate on the outward route (in the direction of arrow B) and the return route (in the direction of arrow C). Then, as shown in FIG. 2, the plurality of slat bars 17 are extremely close to each other so that the gap between the adjacent slat bars 17 is small. Provided. Further, as shown in FIG. 3, both ends of the porous sheet 18 are overlap-locked to spikes 19 erected on the surface of the predetermined slat bar 11, and a stop screw 2 This is firmly joined by a push plate 20 which is screwed to the above-mentioned slot bar 17 by 1. Thus, since the porous sheet 18 is contaminated, it can be easily replaced when the porous sheet 18 is contaminated. The porous sheet 18 may be of any type as long as it has a large number of openings on its surface. For example, porous resin such as sponge, fabric such as woven fabric, knitted fabric, and non-woven fabric; In addition to braided steel wool, vinyl yarn formed into a net shape, and fibers laminated and crimped, it is possible to use a single layer of these or a multilayered layer of these. it can. In this example, a single-layer sponge having a sheet shape was used, and a sponge having an opening area larger than that of the particulate foreign matter was used in consideration of the particulate foreign matter to be removed. As the sponge, for example, a sponge made of a soft urethane foam having a complete open cell structure by treating a polyester urethane foam or a polyether urethane foam can be suitably used. A sponge made of polyester urethane foam has excellent oil resistance, while a sponge made of polyether urethane foam has excellent water resistance, and these may be appropriately selected and used depending on the processing environment. A sponge made of urethane foam is particularly preferable because its pore distribution is more uniform as a whole than a polyether-based sponge. Also, Regarding the number of cells of the dice (the average number of vacancies present on an arbitrary 25 mm straight line from the surface of the sponge to the inside thereof), those having a range of 16 to 34 are preferable, and those having a range of 16 to 2 are more preferable. preferable. If the number of cells is less than 16, the pore diameter becomes too large. For example, when this is used for an extremely small-sized workpiece such as sesame seeds, the workpiece itself is captured and held in the pores. There is a tendency for the recovery rate to decrease, or for foreign matter such as debris of the workpiece to completely block the pores, reducing the efficiency of removing other foreign matter, and conversely, the number of cells exceeds 34 This is because the pore diameter becomes too small, so that foreign matters cannot be sufficiently captured and retained, and the foreign matter removal rate tends to decrease. From the above viewpoints, specifically, in this example, "Molt filter (trade name), MF-20" (manufactured by polyester-based urethane foam) manufactured by Inoatsu Corporation was used for the sponge sheet. In addition, "Maltfill Yuichi, MF-30" (made of polyester urethane foam) or "Maltfill Yuichi, CFH-20 or CFH-30" (also made by Ino Atsuko Co., Ltd.) Polyether urethane foam) can be used.

As shown in FIG. 1, the first foreign matter holding device 10 is tilted as a whole at a predetermined angle 0 with respect to a horizontal plane, and the end in the arrow B direction is the transfer end of the belt conveyor 3. It is arranged to be located below. The inclination angle 0 is set according to the object to be processed, and is set to an angle at which the object to be processed can slide down on the porous sheet 18. For example, if the material to be treated is extremely light, slender or flaky, such as dried leek pieces, dried crab-like pieces, etc., an angle of 50 to 70 ° is preferable, and dried meat pieces, dried shrimp, An angle of 20 to 50 ° is preferable for irregular block or small pieces having a large number of irregularities and corners on the surface, such as dried pulp pieces and dried garlic buds. 15 to 30 if they are roughly spherical, dice-like or spindle-shaped, such as corn grains, dried tofu, almonds, and peanuts, with slight surface irregularities and slight corners. The angle is preferably 5 to 30 if the surface is substantially smooth and has a substantially spherical or elliptical shape, such as beans, chocolate and sesame. Is preferable, and a range of 5 to 70 ° is generally preferable. Further, as shown in FIG. 1, the chute 26 is a plate body having an inverted letter-like shape composed of a vertical side and an inclined side, and the vertical side is the belt conveyor. The first foreign matter holding device 10 is disposed such that the inclined side is located in front of the first foreign matter holding device 10 in the transport direction 3.

 The first foreign matter removing device 30 connects a suction chamber 32 having a suction port 31, a suction pump (not shown), and the suction chamber 32 to a suction pump (not shown). The suction pipe 31 is provided so that the suction port 31 is opposed to the surface of the porous sheet 18 on the outward path with a slight gap.

 Further, the collection packet 34 is a casing having an open upper side, and is provided below the return path of the first foreign matter holding device 10 on the upper side in the direction of arrow C than the suction port 31. I am.

 Further, the second foreign matter holding device 25, the chute 27, the second foreign matter removing device 35, and the collection bucket 36 are the first foreign matter holding device 10, the chute 26, the first foreign matter, respectively. It has the same configuration as the removal device 30 and the recovery bucket 34, and the end of the second foreign matter holding device 25 in the arrow B 'direction is the first foreign matter holding device.

10, the chute 27 is disposed so as to be located below the end in the direction C, and the chute 27 is disposed such that its inclined side is located above the outward path of the second foreign matter holding device 25. The second foreign matter holding device 25 and the foreign matter removing device 35 are disposed below the return path of the second foreign matter holding device 25. Note that the inclination angle of the second foreign matter holding device 25 is

The angle may be the same as or different from the inclination angle of the foreign matter holding device 10 of FIG.

 The collection baguette 40 is a housing having an open top, and is disposed below the end of the second foreign matter holding device 25 in the direction of arrow C ′.

 Next, a description will be given of an embodiment in which the foreign matter is removed from an object to be processed in which the foreign matter is mixed by the removing apparatus 1 having the above configuration.

First, an object to be treated containing foreign substances is supplied onto the belt conveyor 3 of the supply device 2 in an appropriate amount. The supplied workpiece is conveyed by the belt conveyor 3 in the direction of arrow A, and reaches the end in the conveying direction. Here, the workpiece comes into contact with the leveling arm 6 rotating in the direction of the arrow, and when the workpiece is fed onto the belt conveyor 3 in a heaped state, the leveling arm 6 moves the workpiece upward. And flattened. After a while, Drops downward from the end in the conveying direction of the belt conveyor 3 and reaches the forward path of the first foreign matter holding device 10. At this time, the workpiece is guided by the chute 26 and the first foreign matter is surely removed. It is supplied on the outward path of the holding device 10.

 The to-be-processed objects sequentially supplied onto the porous sheet 18 on the outward path of the first foreign matter holding device 10 are divided by the porous sheet 18 because the porous sheet 18 is provided on the downward slope. It slides downward on the quality sheet 18 along the gradient and reaches the second foreign substance holding device 25 via the shot 27. As described above, since the opening of the porous sheet 18 has an opening area larger than that of the particulate foreign matter, the particulate foreign matter mixed in the object to be processed in the process of sliding down on the porous sheet 18 Fits into the opening and is captured and held therein, and the fibrous foreign matter enters the opening at the tip end thereof and is entangled and captured and held therein. Then, in the sliding process, the foreign matter that has not been completely captured by the porous sheet 18 and other objects to be treated other than the foreign matter reach the second foreign matter holding device 25 via the shot 27 as described above.

In this example, the processing object supplied from the belt conveyor 3 onto the porous sheet 18 is thinned and spread by the equalizing means 4, and the processing object is supplied on the porous sheet 18. The foreign materials are liable to be trapped by the porous sheet 18 because they gradually slide down without forming a dumpling state. Further, since the porous sheet 18 is rotated in the direction opposite to the sliding direction of the object to be processed (the direction indicated by the arrow B), it is compared with the case where the porous sheet 18 is stopped or rotated in the forward direction. However, the contact time between the object to be treated and the porous sheet 18 is long, foreign substances can be trapped more efficiently, and a larger amount of treatment is possible. The foreign matter thus captured and held by the porous sheet 18 moves to the return path along with the rotation of the porous sheet 18. Among the foreign substances held in the opening of the porous sheet 18, the foreign substances held in a state of being weakly associated with the opening move to the return path side, then fall off from the opening and are provided immediately below the opening. Collected in the recovered bucket 34. On the other hand, the fibrous foreign matter and the like strongly held in the opening further proceeds in the direction of arrow C to reach the suction port 31 of the first foreign substance removal device 30, and the suction port 31 Aspirated and removed. Then, the portion of the porous sheet 18 that has been purified by the first foreign matter removing device 30 moves to the outward path again by rotation. As described above, the porous sheet 18 captures and holds foreign matter, and the first foreign matter removing device 10 By successively repeating the suction and removal of the foreign matter, the foreign matter can be continuously removed from the workpiece. As described above, since the slat bar 17 that is in contact with the back surface of the porous sheet 18 is provided adjacent to the back surface of the porous sheet 18 without any gap, the flow of air entering the suction port 31 from the back surface side of the porous sheet 18 Can be prevented, and the suction force of the part can be increased.

 On the other hand, in the second foreign matter holding device 25, the process of sliding the foreign matter that could not be captured and retained by the porous sheet 18 in the same manner as in the first foreign matter holding device 10. The remaining object to be processed, which is captured and removed by the above, falls from the second foreign matter holding device 25 and is collected in the collection bucket 40 provided immediately below the second foreign matter holding device 25.

 As described above, according to the removing apparatus 1 of the present example, the objects to be processed can be continuously removed by sequentially and continuously supplying the objects to be processed by the supplying apparatus 2. Further, since the first foreign matter holding device 10 and the second foreign matter holding device 25 are provided in multiple stages, the foreign matter can be removed step by step, and the foreign matter can be reliably removed. By the way, when the object to be treated in which the hair was mixed with the dried vegetable pieces was used as a target and was treated using the removing device 1, about 80% of the hair was recovered in the first foreign matter holding device 10 and, Then, the remaining 20% of the hair was collected in the second foreign matter holding device 25, and all the mixed hair could be collected as the entire device. In addition, in this example, since the sponge is used for the porous sheet 18, the object to be treated is less affected when the object is supplied to the porous sheet 18 or slides on the porous sheet 18. However, even if it is particularly fragile or rugged, such as a slice of dried vegetables, or even fragile, such as a nut, with a slight impact, its shape can be maintained properly. This is the same even if it is something other than a sponge, as long as it is soft and elastic.

 Although not particularly shown in FIGS. 1 and 2, each of the supply device 2, the first foreign matter holding device 10, the second foreign matter holding device 25, the chutes 26, and the chutes 27 is Guide covers are provided at both ends to prevent the workpiece from being scattered outside the equipment while moving.

Although the first embodiment of the present invention has been described above, the following modes can be adopted as modifications of this embodiment. That is, in the above-described example, the porous sheet 18 is rotated in the direction opposite to the sliding direction of the object, but the porous sheet 18 may be rotated in the forward direction. From the viewpoint of continuous processing and the efficiency of processing, it is preferable to slide the object to be processed while rotating the porous sheet 18. Alternatively, the porous sheet 18 may be rotated after completion of sliding to remove foreign matter. However, in these cases, the foreign matter recovery rate is slightly lower than when the porous sheet 18 is rotated in the direction opposite to the sliding direction of the object. Further, instead of rotating the porous sheet 18 continuously, the porous sheet 18 may be rotated intermittently at predetermined intervals.

 Further, in the above-described example, the object to be processed slides naturally on the porous sheet 18. However, the object to be processed slides down by vibrating or vibrating the porous sheet 18. Alternatively, the object to be processed may be configured to vibrate or vibrate on the porous sheet 18 so that the object to be processed climbs on the porous sheet 18 along the gradient. Further, the first foreign matter holding device 10 (similarly to the second foreign matter holding device 25) may be provided horizontally, and the object may be transferred by applying vibration or vibration thereto. .

 The porous sheet 18 may have a non-flat surface and may be provided in a wavy shape or may be provided with protrusions. Further, the porous sheet 18 may have a cylindrical or spherical shape in place of the sheet body. A structure in which a sponge is attached to the slat bar 17 may be used. The use of a material having irregularities on the surface makes it easier to capture foreign matter. In addition, the porous sheet 18 is made of a different material between the first foreign matter holding device 10 and the second foreign matter holding device 25. Or have a different opening area. Further, the first foreign matter holding device 10 and the second foreign matter holding device 25 are provided in multiple stages, but if the first foreign matter holding device 10 can sufficiently remove foreign matter, It is not necessary to provide the holding device 25, the chute 27, the second foreign matter removing device 35, and the collection bucket 36 of 2 in particular.

Further, the first foreign matter holding device 10 and the second foreign matter holding device 25 only need to have at least one inclined surface for sliding down the object to be processed, for example, as shown in FIG. As described above, it may be configured to be a polygon in a front view.

 Further, in the above-described example, the rotation direction of the porous sheet 18 and the like is provided so as to be coincident with the inclination direction, but as shown in FIG. These can also be provided so as to be orthogonal.

As shown in FIG. 6, instead of the first foreign matter removing device 30 and the second foreign matter removing device 35, a first foreign matter removing device 45 having a brush roll 46 and a second foreign matter removing device 45 are provided. The foreign matter removing device 47 may be provided. As shown in the figure, the brush roll 46 is provided so as to abut the entire width of the porous sheet 18, and is driven by an appropriate driving means (not shown) in the direction of the arrow (rotation of the porous sheet 18). In the opposite direction). Among soft and slender foreign substances and fine granular foreign substances, such as hair and lint, there are those which are strongly captured and held by the porous sheet 18. According to the brush roll 46, the tip of the high-density fibrous portion provided on the brush roll 46 comes into contact with the porous sheet 18 while rotating, so that foreign matter is exposed. Because of the forcible removal, it is possible to easily remove from the porous sheet 18 even the above-described elongated foreign matter or fine granular foreign matter. The fibrous member of the brush roll 46 is preferably soft from the viewpoint of protection of the porous sheet 18 and the bristle is preferably about 2 to 5 cm. Further, as shown in FIG. 7, when the fibrous member is inclined forward in the rotation direction and implanted, the effect of removing foreign substances can be improved. Further, as shown in FIG. 8, the brush roll 46 may be formed by spirally winding a brush sheet 46c around a rotating shaft 46. In addition, each of the fibrous members of the brush roll 46 is made hollow, and the hollow portion is connected to a suction means, whereby the foreign material is drawn out of the porous sheet 18 by the fibrous member and is sucked into the hollow portion. You may do it. By doing so, the foreign matter removing effect is further improved. From this aspect, the first foreign matter removing device 45 and the second foreign matter removing device 47 provided with the brush roll 46 are separated from the first foreign matter removing device 30 and the second foreign matter removing device. It is preferable to use them together or integrally. When they are used integrally, it is preferable to install the brush roll 46 in the suction port 31 of the first foreign matter removing device 30 and the second foreign matter removing device. Further, the position where the brush roll 46 is provided is not particularly limited as long as it is on the return path side of the porous sheet 18. However, in consideration of the bending of the porous sheet 18, it is preferable to provide it near the driving sprocket 13 or the driven sprocket 14. Further, a fixed brush may be used instead of the brush roll 46, or a comb-shaped member provided with a hard fibrous member at a low density. These also allow foreign substances to be pushed out of the porous sheet 18 as in the case of the brush roll 46.

 Further, as shown in FIG. 9, it is preferable that a plurality of the chutes 26 and 27 are arranged side by side above the porous sheet 18 along the longitudinal direction thereof (in FIG. Chutes 26 'and 27' are arranged on the opposite side to the directions B and B '). The material to be treated is extremely light, such as a piece of dried green onion, and the foreign matter mixed in the material to be treated is extremely light, such as hair or lint or a piece of the material to be treated, such as a piece of dried green onion. When the object to be treated is supplied on the porous sheet 18 when the object to be treated is substantially equal to or lighter than the object to be treated, as shown in FIG. Collision, reflection, and soaring of the porous sheet 18 cause the particles to pass through the trajectories H and I, which do not slide down on the porous sheet 18, and the foreign matter is not trapped by the porous sheet 18 and remains mixed with the object to be treated. Will be collected. On the other hand, when the chutes 26 ′ and 27 ′ are provided as described above, the so-called processed object is guided by the shot 26 ′ and follows the trajectory J as shown in FIG. And guided on the porous sheet 18. In this way, when the plurality of chutes 26 and 27 are juxtaposed, even if the object to be processed is light and easy to soar, it can be surely slid down on the porous sheet. The foreign substances mixed in the metal can be surely removed. In this case, furthermore, as shown in FIG. 11, a partition 26 a is provided on the shots 26, 26 ′, 27, 27 ′ so as to cover the entire width of the porous sheet 18. It is more preferable to uniformly guide the object to be processed, since the foreign matter removal rate by the porous sheet 18 can be increased. (Second embodiment)

Next, a second embodiment of the present invention will be described. As shown in FIG. 12, the apparatus for removing mixed foreign matter according to the second embodiment comprises a sheet body 5 instead of the porous sheet 18 of the apparatus according to the first embodiment described above. 0 is provided, and the remaining configuration is the same as the device according to the first embodiment. Accordingly, in FIG. 12, parts having the same configuration are denoted by the same reference numerals, and detailed description thereof is omitted. The sheet body 50 is formed by providing a large number of projections at a predetermined density on the surface of a sheet-like substrate, and is formed of granular foreign matter such as sand and elongated fiber-like foreign matter such as Z or hair or lint. Any material may be used as long as it can capture and hold the material. For example, a material in which a large number of mushroom-shaped or hook-shaped protrusions are implanted on the surface of the substrate, or a material in which the protrusions are integrally formed on the surface of the substrate A brush-like one in which fibrous naps are planted on the surface of the substrate; a brush-like one in which a number of fibrous loops are planted on the surface of the substrate; and the pile portion of the pile fabric is cut. Blankets or carpets formed, artificial turf and the like can be applied. In this example, as shown in FIG. 12, a substrate 50a formed by implanting a large number of mushroom-shaped projections 50b on the surface thereof was used. The density at which the protrusions 50b are provided is empirically set to a density at which the foreign matter can be selectively captured and held in consideration of the properties of the protrusion and the properties of the foreign matter to be removed. The sheet body 50 is formed in an endless ring shape so that the projection 50b is on the outside, and is wound around the outer periphery of the slat bar 17 as described above.

 According to this device, similarly to the device according to the above-described first embodiment, the processing object supplied by the supply device 2 is used for the first foreign matter holding device 10 and the second foreign matter holding device 25. It is slid down on the sheet body 50 and collected in the collection bucket 4◦. In the process of sliding down, the particulate foreign matter mixed in the object to be treated is interposed between the projections 50b and is captured and held by the projections 50b, and the fibrous foreign matter is partially or entirely located between the projections 50b. When they enter, they are trapped and retained by being entangled with them, and foreign substances mixed in the workpiece are separated. In addition, since the object is only slid down on the protrusion 50b, even if the object to be processed is a brittle one such as a dried vegetable piece, foreign matter can be removed without losing its shape.

 If the protrusion 50b is formed of a material having flexibility and elasticity (for example, sponge, etc.), when the protrusion 50b is supplied to or slides on the protrusion 50b, it is processed. Appropriate shape of the object to be treated, even if the object receives little impact and the object to be treated is particularly fragile, for example, thin slices of dried vegetables, or irregular, or is easily broken by small impacts, such as nuts It is more preferable that it can be maintained.

The protrusion 50b may be made of a different material or a different shape between the first foreign matter holding device 10 and the second foreign matter holding device 25. In addition, the first difference Instead of the sheet body 50 of one of the object holding device 10 and the second foreign matter holding device 25, the porous sheet 18 capable of capturing and holding the foreign matter is provided. 0b and the porous sheet 18 may be used in combination to remove foreign matter. Incidentally, the same porous sheet as in the first embodiment can be used as the porous sheet 18. Also, in this embodiment, the same modification as the modification of the above-described first embodiment can be adopted.
