2. Description of the Related Art For example, instant noodles in a container are attached 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 produced through a series of processes such as harvesting, washing, chopping, and drying the raw vegetables. Through this production process, granules such as sand or fibrous materials such as twigs, straw, hair, lint, etc. In some cases, the final dried vegetable pieces are mixed or mixed.

[0003] However, in the case of food, it is not preferable from the viewpoint of hygiene when such foreign substances are mixed, and it is necessary to remove these foreign substances in order to avoid complaints from consumers.

Therefore, conventionally, granular foreign substances such as sand are separated by using a mesh-shaped sieve capable of separating dried vegetable pieces and foreign substances, and dried vegetable pieces are placed at an appropriate place for fibrous foreign substances. The inspection worker inspected visually and removed it.

[0005]

However, although particulate foreign substances such as sand can be easily separated by a sieve, fibrous foreign substances such as hair are extremely fine and it is extremely difficult to remove them visually. Further, in particular, hair and the like may be entangled with the dried vegetable pieces, and there is a problem that manual work is extremely inefficient and productivity does not increase. Such problems are not limited to the above-mentioned dried vegetable pieces, but other dried food pieces such as fish and shellfish, food pieces such as beans and cereals, foods such as gums and candy, and anything that may contain other foreign substances. Exists as well.

The present invention has been made in view of the above circumstances, and is intended to remove not only particulate foreign substances such as sand but also mixed foreign substances which can efficiently remove fibrous foreign substances. It is intended to provide a method and a removal device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 an apparatus for removing mixed foreign substances according to the present embodiment, and FIG. 2 is a perspective view showing a part of the apparatus. As shown in FIG. 1, the removing device 1 includes a supply device 2 that supplies an object to be processed, and a first foreign substance holding device 10 and a second foreign substance holding device 25 that are sequentially provided below the supply device 2. The first foreign matter holding device 1
A first foreign matter removing device 30, a second foreign matter removing device 35 provided below the 0 and the second foreign matter holding devices 25, collecting buckets 34, 36, 40, and chutes 26, 27. It is. Hereinafter, the details of these units will be described.

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

The first foreign matter holding device 10 includes a pair of a driving rotary shaft 11 and a driven rotary shaft 1 which are juxtaposed at appropriate intervals.
2, a pair of drive sprockets 13 arranged side by side with the drive rotating shaft 11 at appropriate intervals, and a pair of driven sprockets 14 arranged side by side at an appropriate interval on the driven rotary shaft 12;
The pair of the driving sprocket 13 and the driven sprocket 1
4 and a plurality of slat bars 17 shown in FIG. 2 which are laid on the pair of chains 15 via the mounting stays 16 and are formed in an endless ring shape as a whole. A porous sheet 18 wound around the outer periphery of the slat bar 17 and also formed in the shape of an endless ring; and a drive unit (not shown) for rotating the drive rotary shaft 11 in the direction of arrow D. By driving the drive unit (not shown) to rotate the drive sprocket 13 in the direction of arrow D, the chain 15, the slat bar 17 and the porous sheet 18 are moved outward (see FIG. 1). It turns around and turns sequentially in the direction of arrow B) and the return path (direction of arrow C).

As shown in FIG. 2, the plurality of slat bars 17 are provided so as to be extremely close to each other so that the gap between the adjacent slat bars 17 is small. ing. As shown in FIG. 3, both ends of the porous sheet 18 are overlap-locked with spikes 19 erected on the surface of the slat bar 17. This is firmly joined by the pressed plate 20 to be worn. In this way, the porous sheet 18 can be easily replaced when the porous sheet 18 becomes soiled.

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, woven fabric, knitted fabric, nonwoven fabric, etc. Fabrics, braided steel wool, vinyl yarns formed into a net shape, fibers laminated and crimped, etc. can be used. Use a single layer of these or a multi-layered structure Can be. In this example, a single-layer sheet-like sponge 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. The sponge made of is particularly preferable because the pore distribution is entirely uniform as compared with the polyether-based sponge. The number of cells of the sponge (the average number of holes existing on an arbitrary 25 mm straight line from the surface of the sponge to the inside thereof) is preferably in the range of 16 to 34,
Those having a range of 4 are more preferable. If the number of cells is less than 16, the pore diameter becomes too large. For example, when this is used for a very small particle such as sesame seed, the substance itself is captured and held in the pores and collected. When the rate is reduced, or there is a tendency that foreign matter such as debris of the object to be processed completely closes the pores and the efficiency of removing other foreign matter decreases, and conversely, when the number of cells exceeds 34, This is because the pore diameter becomes too small, so that the foreign matter cannot be sufficiently captured and held, and the removal rate of the foreign matter tends to decrease.
From the above viewpoint, specifically, in this example, "Molt Filter (trade name), MF-20" (manufactured by polyester urethane foam) manufactured by Inoac Corporation was used for the sponge sheet. In addition, in addition to the above, "Mort filter, MF-
30 "(made of polyester urethane foam) or" Malt filter, CFH-20 or CFH-30 "
(Made of polyether-based urethane foam) can be used.

As shown in FIG. 1, the first foreign matter holding device 10 is inclined at a predetermined angle θ with respect to the horizontal plane as a whole, and the end of the first foreign matter holding device 10 in the direction of arrow B is the transfer end of the belt conveyor 3. It is arranged to be located below. This inclination angle θ is set according to the object to be processed,
The angle is set so that the object can slide down on the porous sheet 18. For example, if the material to be treated is extremely light and slender or flaky, such as dried leek pieces, dried crab-like pieces, etc., the angle is preferably 50 to 70 °, and dried meat pieces, dried shrimp, dried flesh pieces are preferred. The angle is preferably 20 to 50 ° for irregular blocks or small pieces having a large number of irregularities and corners on the surface, such as buds of dried garlic and the like, and dried corn grains, dried tofu, and almonds The angle is preferably 15 to 30 ° for a roughly spherical or dice-like or spindle-like shape having slight irregularities and corners on the surface, such as grains of peanuts, peanuts, and the like, and beans, chocolate balls, sesame, and the like. If the surface is substantially smooth and has a regular, substantially spherical or elliptical shape as described above, the angle is preferably from 5 to 30 °, and more preferably from 5 to 70 °.

Further, as shown in FIG. 1, the chute 26 is a plate having an inverted letter-like shape composed of a vertical side and an inclined side, and the vertical side is the belt conveyor 3. This is disposed so that the inclined side is located above the outward path of the first foreign matter holding device 10.

The first foreign matter removing device 30 includes a suction chamber 32 having a suction port 31, a suction pump (not shown), and a suction connecting the suction chamber 32 and a suction pump (not shown). The suction port 31 is disposed so as to face the surface of the porous sheet 18 on the outward path with a slight gap.

The collecting bucket 34 is a housing having an open top, and is provided below the return path of the first foreign matter holding device 10 on the upper side of the suction port 31 in the direction of arrow C. I have.

The second foreign matter holding device 25, the chute 27, the second foreign matter removing device 35, and the collecting bucket 3
Numeral 6 has the same configuration as the first foreign matter holding device 10, the chute 26, the first foreign matter removing device 30, and the collecting bucket 34, and the second foreign matter holding device 25 is indicated by an arrow B '. The direction end is the first foreign matter holding device 1
The chute 27 is disposed such that its inclined side is located above the outward path of the second foreign substance holding device 25, and the second foreign substance is disposed. The removing device 35 and the collecting bucket 36 are disposed below the return path of the second foreign matter holding device 25, respectively. The second
The inclination angle of the foreign substance holding device 25 may be the same as or different from the inclination angle of the first foreign substance holding device 10.

The collecting bucket 40 is a casing 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 the 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 processed in which foreign matters are mixed is supplied in an appropriate amount onto the belt conveyor 3 of the supply device 2. 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 contacts 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 workpiece is scraped by the leveling arm 6 and flattened. Is done. Thereafter, the object to be processed falls from the end of the belt conveyor 3 in the transport direction and reaches the first foreign matter holding device 10 on the outward path. At this time, the object to be processed is guided by the chute 26 to be sure. It is supplied on the outward path of the first foreign matter holding device 10.

The object to be processed sequentially supplied onto the porous sheet 18 on the outward path of the first foreign matter holding device 10 has the porous sheet 18 provided at a downward slope. The upper part slides downward along the slope, and passes through the chute 27 to the second foreign matter holding device 25.
Leads to. As described above, the opening of the porous sheet 18 has an opening area larger than that of the particulate foreign matter. The fibrous foreign matter has its tip entering the opening and is entangled with it and is captured and held therein. In the sliding process, the foreign matter not captured by the porous sheet 18 and other objects to be processed other than the foreign matter reach the second foreign matter holding device 25 via the chute 27 as described above.

In this embodiment, the object to be processed supplied from the belt conveyor 3 onto the porous sheet 18 is thinned and spread by the leveling means 4. Foreign substances are easily trapped in the porous sheet 18 because they slide down smoothly sequentially without entering a state. In addition, since the porous sheet 18 is rotated in the direction opposite to the sliding direction of the workpiece (the direction indicated by the arrow B), compared to the case where the porous sheet 18 is stopped or rotated in the forward direction,
The contact time between the object to be processed and the porous sheet 18 is long, foreign substances can be trapped more efficiently, and more processing can be performed.

The foreign matter thus captured and held by the porous sheet 18 moves toward the return path 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 and then fall out of the opening to be provided immediately below the opening. Collected in the bucket 34. On the other hand, the fibrous foreign matter and the like strongly held by the opening further proceeds in the direction of arrow C to reach the suction port 31 of the first foreign matter removing device 30, and is sucked and removed by the suction port 31. Is done. 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, by successively repeating the capturing and holding of the foreign matter by the porous sheet 18 and the suction and removal of the foreign matter by the first foreign matter removing device 10, the foreign matter can be continuously removed from the object to be processed. As described above, since the slat bar 17 which is in contact with the back surface of the porous sheet 18 is provided so as to be adjacent without any gap, the flow of air entering the suction port 31 from the back surface side of the porous sheet 18 is prevented. And the suction force of the part can be increased.

On the other hand, in the second foreign matter holding device 25, as in the case of the first foreign matter holding device 10, foreign matter that has not been completely captured and retained on the porous sheet 18 is captured in the process of sliding down. The other object to be removed that has been removed and falls from the second foreign matter holding device 25 is collected by the collection bucket 40 provided immediately below the second foreign matter holding device 25.

As described above, according to the removing apparatus 1 according to the present embodiment, the objects to be processed are sequentially and continuously supplied by the supplying apparatus 2, so that the foreign substances mixed therein can be continuously removed. . 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 processed in which the hair was mixed with the dried vegetable pieces was processed using the removing device 1, about 80% of the hair was recovered in the first foreign matter holding device 10, The remaining 20% of the hairs were recovered in the second foreign matter holding device 25, and all the mixed hairs could be recovered as the entire device. Further, in this example, since the sponge is used for the porous sheet 18, the object to be processed is less affected when the object is supplied to the porous sheet 18 or slides on the porous sheet 18, and therefore, the object to be processed is dried. Even if it is particularly brittle or has irregularities such as vegetable slices, and even if it is easily broken by a slight impact such as nuts, its shape can be maintained properly. This is the same even if it is something other than a sponge as long as it is flexible and elastic.

Although not shown in FIGS. 1 and 2, both ends of the supply device 2, the first foreign matter holding device 10, the second foreign matter holding device 25, the chute 26, and the chute 27 are provided. Is provided with a guide cover, and the object to be processed is prevented from being scattered outside the apparatus during movement by the guide cover.

Although the first embodiment of the present invention has been described above, the following embodiment can be adopted as a modification of this embodiment.

That is, in the above 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, and the porous sheet 18 may be rotated from the viewpoint of continuous processing and efficient processing. It is preferable that the object to be processed is slid down while rotating. However, the porous sheet 18 is stopped while a certain amount of the object to be slid down. It may be removed. 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.

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

The surface of the porous sheet 18 may not be flat, but may be wavy or provided with protrusions. Further, the porous sheet 18 may be cylindrical or spherical in place of the sheet. Of the sponge into the slat bar 17
It may be configured to be adhered to. The use of a material having an uneven surface as described above makes it easier to capture foreign matter.

The porous sheet 18 may be made of a different material or have a different opening area between the first foreign matter holding device 10 and the second foreign matter holding device 25.

The first foreign matter holding device 10 and the second foreign matter holding device
Are provided in multiple stages, but if the first foreign matter holding device 10 can sufficiently remove foreign matter, the second holding device 25, the chute 27, and the second foreign matter removing device 35 And the collection bucket 36 is not particularly provided.

The first foreign substance holding device 10 and the second foreign substance 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. Alternatively, it may be configured to be a polygon in a front view.

In the above-described example, the rotating direction of the porous sheet 18 and the like are provided so as to coincide with the inclination direction. However, as shown in FIG. 5, the rotating direction and the inclination direction are orthogonal to each other. These can be provided as described above.

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 are provided. The removal device 47 may be provided. As shown in the figure, the brush roll 46 is used for the porous sheet 1.
8 is provided so as to be in contact with the entire width thereof, and is rotated in an arrow direction (a direction opposite to the rotating direction of the porous sheet 18) by a driving means (not shown) as appropriate. Some soft and slender foreign matter and fine granular foreign matter, such as hair and lint, are strongly captured and held by the porous sheet 18. This brush roll 4
According to 6, the tip of the high-density fibrous portion provided on the brush roll 46 is rotated while the porous sheet 1 is rotated.
8, the foreign matter is forcibly removed by scraping out the foreign matter, so that even a foreign matter having an elongated shape or a fine granular matter can be easily removed from the porous sheet 18. The fibrous member of the brush roll 46 is preferably soft from the viewpoint of protection of the porous sheet 18.
