Description

  The present invention relates to a peeling hair removing apparatus and a peeling hair removing method for removing peeling hair (peeled yarn-like or hair-like object such as enamel hair) from a can, and in particular, to effectively remove enamel hair. The present invention relates to a peeling hair removal apparatus and a peeling hair removal method that can improve economy and productivity.

The can is a container made of a metal plate, and the metal plate to be used is usually coated with a paint or a resin before the can making process. The coated metal plate is formed into a predetermined shape in the can making process, and at this time, a part of the paint, resin, or the like may be peeled off into a thread shape or a hair shape. In addition, in the filling process, which is a subsequent process of the can manufacturing process, a part of the paint or resin may be peeled off in the same manner. Depending on the material of the peeled thread-like or hair-like object, it is called enamel hair, coat hair, thermoplastic resin hair or the like.
In addition, in this specification, the thread-like or hair-like object peeled from the can is generically referred to as peeled hair regardless of its material.

In addition, in cans in which score processing is performed on a coated metal plate (for example, corned beef cans), the score or paint in the vicinity of the score is peeled off into a thread shape, and peeling hair resulting from score processing (in the case of corned beef cans) , Enamel hair).
Next, corned beef cans and enameled hair of corned beef cans will be described.

  The corned beef is a square can having a special trapezoidal square shape (a truncated quadrangular pyramid shape), and is configured to divide and open the can body by winding the take-up portion. The winding portion to be wound has a width of about 5 mm, and two scores (the two scores are separated from each other by about 1 mm) are formed on the upper portion and the lower portion of the winding portion, respectively. Has been. If it does in this way, when winding up a winding part, the malfunction that it will remove | deviate from two scores and a can body will be cut | disconnected can be prevented.

The can body has a chromate-treated tin-plated steel sheet, a white coat layer, a printing layer such as letters, and a finishing varnish layer (these layers are appropriately referred to as a printing film) in this order. It is a laminated metal plate.
In the can making process, the metal plate coated with the printed film is first cut into a predetermined shape by punching. The punched metal plate has a flat plate shape.
Next, the punched metal plate is pushed into the printing surface while rotating the score cutter, whereby four scores are formed. Each score is a linear groove. For example, the cross section of the groove is a substantially triangular shape inverted, and the width of the groove is about 0.1 mm.

When the score is formed, a large surface pressure acts on the surface of the score (that is, the pair of inclined surfaces of the groove), and the lower surface of the printed film (the lower surface of the white coat layer) and the metal surface (the chromate-treated surface) A shearing force is applied between them, resulting in a decrease in adhesion.
Furthermore, cracks may occur in the printed film along the edge of the score (upper edge of the groove slope) and the center of the score (lower edge of the groove slope). Especially in such a case, even if no cracks are generated, the printed film of the score peels off in a thread form due to bending after scoring or rubbing with the chute during conveyance, and several mm to about An enamel hair with a length of 30 mm is generated.

  In addition, as described above, the corned beef can generally have a white coat layer containing a titanium oxide pigment on the base of the printing layer, so that enamel hair is easily noticeable, and the white coat is a pigmented paint. For this reason, the adhesion to the metal surface (here, the chromate-treated surface) is weak, and enamel hair tends to occur. Furthermore, since the can body seam can be made by soldering or welding, the metal plate is plated with tin, and in this respect too, the adhesion to the paint is weak and the enamel hair is The situation is likely to occur.

(Conventional example)
Next, a conventional enamel hair removing apparatus for removing enamel hair from a corned beef can will be described with reference to the drawings.
FIG. 5: is the schematic of the principal part of the enamel hair removal apparatus concerning a prior art example, (a) has shown the top view, (b) has shown DD expanded sectional drawing.
In FIG. 5, an enamel hair removing apparatus 101 as a peeling hair removing apparatus includes a magnet conveyor 11, a pair of channel brushes 102, a pair of suction ducts 105, and the like.
The corned beef 6 in the enamel hair removing step is an empty can made up of a can body and an upper lid (the bottom cover is attached after filling the corned beef). The winding part 61 is formed by the score 62.

  The magnetic conveyor 11 as a conveying means conveys the inverted top of the corned beef can 6 while being attracted by a magnetic force. At this time, the corned beef 6 which is a substantially rectangular can is transported in a direction in which the side surface in the longitudinal direction is parallel to the transport direction. In addition, a pair of guide rails 12 are provided on both sides of the magnet conveyor 11 so as to face each other, and guides the corned beef can 6 so that its orientation does not change.

  The pair of channel brushes 102 includes a channel member 121 and a brush 122, and are fixed to the base 10 via holding means (not shown) so as to sandwich the magnet conveyor 11. In each channel brush 102, the tip of the brush 122 abuts on the score 62 of the corned beef 6 and enamel hair (not shown) peels from both side surfaces in the longitudinal direction.

  The suction duct 105 has a substantially rectangular parallelepiped shape having an upper plate, a back plate, a pair of side plates, and the like, and a plurality of suction ports 155 are provided on the upper plate. The suction duct 105 is fixed so as to cover the channel brush 102 in a state where the tip end portion of the brush 122 protrudes toward the corned beef 6. The suction port 155 communicates with a suction port of a dust collector (not shown), and the enamel hair removed by the channel brush 102 is sucked upward by the suction duct 105 and discharged from the suction port 155 to the dust collector. The

Various techniques related to the present invention have been proposed.
For example, Patent Document 1 discloses a can coat hair that has a brush that revolves and rotates and that can move forward and backward in the can and removes the coat hair (enamel hair) at the flange tip of the draw can (DR can). The technology of the removal device is disclosed. This can coat hair removal device is provided with a dust scattering prevention cover so as to cover the movement range of the brush, sucks the removed coat hair and removes it to the outside of the device.

Furthermore, various techniques for suppressing the occurrence of enamel hair itself have been proposed.
For example, Patent Document 2 discloses a technique for a metal can lid covering coating material that suppresses the generation of enamel hair at the time of molding or opening a lid by dispersing thermoplastic resin particles in the coating material. Yes.
Patent Document 3 discloses a technology of a coated steel sheet for flange bending that does not generate enamel hair on the end face during flange bending by reducing the thickness of the coating film to half or less of the surface unevenness of the steel sheet. It is disclosed.
Patent Document 4 discloses a technique of a method for processing a flange edge portion of a metal can that prevents the enamel hair from falling off by applying a paint to the flange edge portion.

However, the enamel hair removing apparatus 101 described above has been desired to improve the removal rate of enamel hair. In other words, enamel hair can be removed effectively even if a large amount of enamel hair is generated because the rate of occurrence changes suddenly depending on the sharpness of the score cutter and the adhesion of the printed film. There was a demand for the establishment of technology that can be used.
In addition, as described above, when the score cutter becomes poor in sharpness, enamel hair is likely to occur. Therefore, it is necessary to frequently replace and re-polish the score cutter, thereby reducing the cost of re-polishing and improving productivity. There was a problem that it was not possible to plan.

In addition, although the technique of patent document 1 is a technique relevant to this invention, it cannot solve said subject, and is applied to square cans, such as a corned beef, in the state excellent in economical efficiency. It was difficult.
Further, in the techniques of Patent Documents 2 to 5, in order to suppress the generation of enamel hair, improvement of the adhesion of the coating film, improvement of the surface treatment of the metal, and ingenuity in processing have been made, but the generation of enamel hair Cannot be sufficiently suppressed, and it has been difficult to solve the above problems.

  The present invention has been proposed to solve the above-described problems, and can effectively remove enamel hair and the like, and a peeling hair removal device that can improve economy and productivity. It is another object of the present invention to provide a peeling hair removal method.

  In order to achieve the above object, the peeling hair removing device of the present invention is a peeling hair removing device that removes peeling hair from a can, and a conveying means that conveys the can, and a suction device for sucking the peeling hair A rotating brush that scrapes the peeling hair from the can and a suction duct that communicates with the suction channel and sucks and discharges the peeling hair.

  Further, the peeling hair removing method of the present invention is a peeling hair removing method for removing peeling hair from a can, wherein a conveying means conveys the can and has a suction channel for sucking the peeling hair. A brush abuts on the can that is being transported to scrape the peeling hair from the can, and a suction duct removes at least a portion of the scraped hair that has been scraped off from the suction flow of the rotating brush. As a method of sucking through a path.

  According to the peeling hair removal apparatus and peeling hair removal method of this invention, enamel hair etc. can be removed effectively and economical efficiency, productivity, etc. can be improved.

[Embodiment of Peeling Hair Removal Device]
FIG. 1: has shown the schematic plan view of the principal part of the enamel hair removal apparatus concerning one Embodiment of this invention.
FIG. 2 shows an AA enlarged sectional view of FIG.
1 and 2, the peeling hair removing device of the present embodiment is an enamel hair removing device 1, and includes a magnet conveyor 11 that conveys a corned beef can 6 and a suction channel 213 for sucking enamel hair 63. The segment-type roll brush 2 that scrapes the enamel hair 63 from the corned beef 6 and the suction duct 5 that communicates with the suction channel 213 and sucks and discharges the enamel hair 63 are provided.
The enamel hair removing device 1 scrapes the enamel hair 63 from the corned beef can 6 conveyed by the magnet conveyor 11 with the segment type roll brush 2 and removes it with the suction duct 5.
Note that the corned beef can 6 of the present embodiment is substantially the same as that of the conventional example described above.

(Magnet conveyor)
The magnet conveyor 11 as a conveying means is substantially the same as that of the above-described conventional example, and conveys the inverted top cover of the corned beef can 6 while being attracted by a magnetic force. At this time, the corned beef 6 which is a substantially rectangular can is transported in a direction in which the side surface in the longitudinal direction is parallel to the transport direction.
A pair of guide rails 12 are provided on both sides of the magnet conveyor 11 so as to face each other, and guides the corned beef 6 so that the direction of the corned beef 6 does not change. Furthermore, the guide rail 12 of this embodiment is provided with a hair removal member 4 to be described later at a portion corresponding to the segment-type roll brush 2 or the like.

(Segment type roll brush)
FIG. 3: is a schematic enlarged view of the principal part for demonstrating the rotating brush of the enamel hair removal apparatus concerning one Embodiment of this invention, (a) has shown the top view, (b) is B- B sectional drawing is shown, (c) has shown CC sectional drawing.
In FIG. 3, the rotating brush is a segment-type roll brush 2, and is disposed to face both sides of the magnet conveyor 11. In the illustrated example, two brush rolls 21 are connected and used. That is, the enamel hair removing apparatus 1 has a configuration in which the conveying means is the magnet conveyor 11 and the segment type roll brush 2 is disposed on both sides of the magnet conveyor 11. Thereby, the enamel hair 63 can be efficiently removed from both sides of the corned beef can 6. Moreover, the overall structure of the enamel hair removing apparatus 1 can be simplified, and the manufacturing cost can be reduced.

  The segment-type roll brush 2 has two brush rolls 21 that are attached adjacent to each other, a pair of zigzag collars 22 that sandwich the brush rolls 21, and a shaft 23 to which the brush rolls 21 and the zigzag collars 22 are attached. ing. The segment-type roll brush 2 has a suction channel 213 for sucking the enamel hair 63.

The brush roll 21 has a substantially cylindrical brush base 211 and a brush 212 planted on the brush base 211.
The brush base 211 is formed in the center portion of the circumferential surface so that three elongated holes 214 along the rotation center axis are positioned at equal intervals in the circumferential direction. That is, the brush base 211 has the brush 212 planted over the entire circumference on the outer peripheral surface in the vicinity of both ends, and on the outer peripheral surface on the center side at three linear locations along the rotation center axis (circumference). Brushes 212 are implanted so that they are positioned at equal intervals in the direction.

Further, the brush stand 211 is formed with crown-gear-shaped irregularities at both ends, and the irregularities engage with the zigzag collar 22 and the like, and transmit torque from the shaft 23.
Further, since the adjacent brush bases 211 are engaged with each other through the above-described unevenness, the phase of each opening 214 can be easily set. In the present embodiment, the phases of the openings 214 of the adjacent brush bases 211 are matched, but the present invention is not limited to this. The above phases may be different from each other by a predetermined angle, for example, 60 degrees.
The brush base 211 and the brush 212 are usually made of resin.

In the shaft 23, two brush rolls 21 are fitted in the center portion, and a zigzag collar 22 that sandwiches the two brush rolls 21 is further fitted. The zigzag collar 22 in which the shaft 23 is fitted is fixed to the shaft 23 by a hexagon socket set screw or the like.
The shaft 23 has a diameter corresponding to the opening 214 of the brush roll 21 smaller than the inner diameter (for example, 20 mm) of the brush base 211 (for example, 14 mm). A cylindrical space 215 is formed between the inner peripheral surface of 211. Furthermore, the shaft 23 is usually made of metal.
The cylindrical space 215 may be formed by boring the brush base 211.

As shown in FIG. 1, the shaft 23 is rotatably supported at both shaft ends by a bearing holder 24, and a bevel gear 25 is fixed to the shaft end on the conveyance direction side. The bevel gear 25 is engaged with a bevel gear 31, and the bevel gear 31 is connected to a sprocket 33 via a shaft 32, and the shaft 32 is rotatably supported by a bearing holder 34. .
In this embodiment, although not shown, the sprocket 33 is connected to the drive shaft of the magnet conveyor 11 and the like via a chain or the like. Thereby, since the enamel hair removal apparatus 1 does not need to provide an exclusive motor (not shown) etc., it can aim at cost reduction, such as manufacturing cost.

The segment roll brush 2 has a suction channel 213 for sucking the enamel hair 63. In this embodiment, the suction channel 213 includes the opening 214 and the cylindrical space 215 described above. It is made up of. That is, the segment type roll brush 2 has openings 214 arranged in three directions at intervals of 120 ° with respect to the rotation center axis, and the three openings 214 communicate with the cylindrical space 215.
In this way, the segment-type roll brush 2 can alternately scrape the enamel hair 63 with the brush 212 and suck the enamel hair 63 with the suction channel 213 with respect to the corned beef 6. As a result, the suction channel 213 can quickly suck and discharge the enamel hair 63 scraped by the group of brushes 212, thereby preventing the scraped enamel hair 63 from being entangled with the brush 212. Can do. Further, since the brush 212 is in contact with the enamel hair 63 partially protruding by the suction of the suction channel 213 in a state where the enamel hair 63 is not tangled, the scraping performance can be improved. Therefore, the segment type roll brush 2 can effectively remove the enamel hair 63.

In the segment-type roll brush 2 of this embodiment, the angle α of the group of brushes 212 is about 60 °, and the angle β of the sucked region is about 60 °. However, the angles α and β are not limited to those described above. For example, even when α = 50 ° to 70 ° and β = 70 ° to 50 °, substantially the same effect as described above can be obtained.
In the present embodiment, the three openings 214 are formed. The reason for this is that if four or more openings 214 are formed, the mechanical strength of the brush base 211 becomes weak, and the scraping efficiency decreases. It is because it does. Further, when one or two openings 214 are formed, it becomes difficult to suck the enamel hair 63 quickly, and the enamel hair 63 is likely to be entangled with the brush 212.

(Hair removal member)
In addition, the enamel hair removing apparatus 1 of the present embodiment has a predetermined angle θ (in this embodiment, the angle θ is determined from the position where the brush 212 of the segment-type roll brush 2 contacts the corned beef 6 (the position in the horizontal direction). A hair removal member 4 that abuts on the brush 212 is provided at a position separated from the segment-type roll brush 2 in the rotational direction by about 45 ° (see FIG. 2). The hair removing member 4 is usually a metal round bar (which may be an elongated plate-like member or a square bar) and an organic material (for example, rubber tube) with high frictional resistance covering the round bar. It is set as the structure which has. As a result, when the hair removing member 4 and the brush 212 come into contact with each other, as will be described later, the enamel hair 63 partially connected to the corned beef 6 is sandwiched and effectively pulled from the corned beef 6. Thus, the removal rate of the enamel hair 63 can be further improved.

The hair removal member 4 has an entry side portion in the conveyance direction bent outward and functions as a guide rail 12. Furthermore, the member 4 for hair removal is set as the structure which does not rotate normally.
Moreover, although the angle θ is about 45 °, the angle θ is not limited to this. For example, the angle θ may be 35 ° to 55 °, and substantially the same effect can be obtained.

(Suction duct)
The suction duct 5 has a substantially rectangular parallelepiped shape including an upper plate 51, a lower plate 52, a pair of side plates 53, a back plate 54, and the like, and a plurality of suction ports 55 are provided in the back plate 54. The suction port 55 communicates with a suction port of a dust collector (not shown), and the enamel hair 63 scraped by the segment type roll brush 2 is sucked in the left and right directions by the suction duct 5 (see FIG. 4), and is discharged from the suction port 55 to the dust collector.

  Here, preferably, the suction duct 5 is fixed so as to cover the brush roll 21 in a state where a part of the brush roll 21 protrudes toward the corned beef 6. In the present embodiment, the end portions of the upper plate 51, the lower plate 52, and the pair of side plates 53 are positioned on the side of the corned beef 6 by a minute distance (for example, several mm) from the rotation center axis of the shaft 23. The side plate 53 has a shape corresponding to the outer shape of the zigzag collar 22. That is, the suction duct 5 has a vacuum guide (upper plate 51, lower plate 52, so as to cover a predetermined area of the segment-type roll brush 2 (substantially the portion on the corned beef 6 side from the rotation center axis of the brush roll 21). A pair of side plates 53 and a back plate 54) are provided. In this way, the state in which the two openings 214 are located on the side of the corned beef 6 and the state in which one opening 214 is located on the side of the corned beef 6 are alternately repeated, and the opening 214 is strong. Since the enamel hair 63 is sucked with the suction force and rotating, the suction efficiency can be improved.

Preferably, the suction port 55 is provided on the opposite side of the corned beef can 6 with respect to the segment type roll brush 2. In this case, for example, air can easily pass through the suction channel 213 as compared with the case where the suction port 55 is provided in the upper plate 51 (not shown), and thus the enamel hair 63 is efficiently discharged. (See FIG. 4). Further, as will be described later, the scraped enamel hair 63 can be quickly sucked.
The position of the suction port 55 is not limited to the above. For example, the suction port 55 may be provided on the opposite side of the corned beef can 6 with respect to the segmented roll brush 2 and on the lower side thereof. The effect of can be obtained.

(Canned corned beef)
In the present embodiment, the can is a corned beef 6.
As described above, the corned beef 6 is provided with four scores 62 on the can body and is difficult to take measures against enamel hair. However, the corned beef 6 has a suction channel 213 and is a rotating segment type roll brush. 2, the enamel hair 63 can be effectively removed.

The corned beef 6 is a rectangular can, and the side surface in the longitudinal direction is formed into a shape in which the central portion is recessed inward by bending or overhanging after scoring, and the side surface in the short side is bent. Is formed into a shape curved outward. That is, the score 62 on the side surface in the longitudinal direction is a portion where the adhesion is further lowered in addition to the decrease in adhesion in the score processing, and the enamel hair 63 is likely to be generated by peeling of the printed film. The enamel hair removing apparatus 1 can efficiently remove the enamel hair 63 on the side surface in the longitudinal direction.
In the present embodiment, the enamel hair removing device 1 is applied to the side surface in the longitudinal direction of the corned beef 6. However, the present invention is not limited to this. For example, the direction of the corned beef 6 is 90 °. It is good also as a structure which changes and conveys and applies the enamel hair removal apparatus 1 also to the side surface of a transversal direction.

  Furthermore, the enamel hair removing apparatus 1 is configured to remove the enamel hair 63 from the corned beef 6 that is an empty can. If it does in this way, generation | occurrence | production of the enamel hair 63 can be prevented in the conveyance process, filling process, etc. after passing the enamel hair removal apparatus 1, For example, the malfunction that a filling line etc. becomes dirty with the enamel hair 63 is avoided. can do.

Next, operation | movement of the enamel hair removal apparatus 1 of the said structure etc. are demonstrated with reference to drawings.
FIG. 4: has shown schematic expanded sectional drawing of the principal part for demonstrating operation | movement of the enamel hair removal apparatus concerning one Embodiment of this invention.
In FIG. 4, the corned beef 6 is conveyed by the magnet conveyor 11, and the segment-type roll brush 2 is normally rotated at a rotational speed of several revolutions per second.
Here, the magnet conveyor 11 conveys the corned beef can 6 while being attracted by a magnetic force, and the segment-type roll brush 2 is in a direction in which the brush 212 is in contact with the longitudinal side surface of the corned beef can 6 from the upper side to the lower side. Rotate. At this time, since the corned beef 6 is pressed against the magnet conveyor 11 by the rotation of the brush 212, it can be reliably conveyed. Moreover, since the scraped enamel hair 63 moves downward, it is possible to prevent a problem such as intrusion into the inside of the corned beef 6.

First, as shown in FIG. 4A, the first opening 214 a is at a position almost opposite to the score 62. At this time, the space in the vicinity of the score 62 is surrounded by the third group of brushes 212c and the first group of brushes 212a, and the air in this space is supplied to the first opening 214a, the cylindrical space 215, and Then, the air is sucked into the suction port 55 through the second opening 214b or the third opening 214c. In this suction, since the tip end of the suction is substantially the first opening 214a, the suction force is increased, and the enamel hair 63 is raised in the vicinity of the score 62, that is, one end of the enamel hair 63 is peeled off. Although protruding, the other end is connected to the corned beef 6. Alternatively, although not peeled off from the corned beef can 6, the enamel hair 63 is likely to rise when rubbed by the first group of brushes 212 a.
Although not shown, in the second group of brushes 212b, the enamel hair 63 adhering to the second group of brushes 212b is almost certainly sucked into the suction port 55 here.

Next, as shown in FIG. 4B, when the segment-type roll brush 2 further rotates, the first group of brushes 212 a comes into contact with the enamel hair 63 and scrapes the enamel hair 63. At this time, the air in the space surrounded by the third group of brushes 212c and the first group of brushes 212a passes through the first opening 214a, the cylindrical space 215, and the third opening 214c, and then the suction port. 55 is sucked. The air flow is substantially linear, and the enamel hair 63 thus scraped off is quickly and reliably sucked into the suction port 55.
The air in the space surrounded by the first group of brushes 212a and the second group of brushes 212b passes through the second opening 214b, the cylindrical space 215, and the third opening 214c, and then the suction port 55. Sucked into. Thereby, since the upward air of the opened corned beef can 6 is sucked, even if there is the enamel hair 63 that has risen, it is possible to prevent the trouble of sucking and dropping into the corned beef 6.

  Here, preferably, the tip portions of the upper plate 51 and the lower plate 52 may be extended to the side of the corned beef can 6 as indicated by broken lines. In this way, the air in the space surrounded by the third group of brushes 212c and the first group of brushes 212a can be more strongly sucked, and the scraped enamel hair 63 can be sucked more quickly and reliably. Sucked into the mouth 55.

  In addition, the enamel hair 63 that is in contact with the first group of brushes 212a and peeled off from the corned beef 6 is sucked into the suction port 55 as described above, but in the enamel hair 63, the first group of brushes 212a and There are those that come into contact and have one end peeled off from the corned beef can 6 but the other end connected to the corned beef can 6. One end of the enamel hair 63 usually moves downward together with the brush 212a.

  As shown in FIG. 4 (c), the enamel hair 63, which is partly connected to the corned beef can 6, but the segment-type roll brush 2 is further rotated as shown in FIG. The segment-type roll brush 2 rotates while being sandwiched between the removal member 4 and is transported, and the corned beef 6 is transported to be shredded from the corned beef 6. That is, the enamel hair removing device 1 can remove the enamel hair 63 more reliably by including the hair removing member 4. Further, the enameled hair 63 that has been shredded is normally sucked into the suction port 55 through the first opening 214a, the cylindrical space 215, and the third opening 214c.

As described above, the enamel hair removing device 1 rubs the score 62 on the side surface in the longitudinal direction of the corned beef 6 where the enamel hair 63 easily occurs with the segment-type roll brush 2, scrapes the enamel hair 63 from the score 62, and The enamel hair 63 can be sucked through the suction flow path 213 and the suction duct 5 in the type roll brush 2 and captured by a filter (not shown) of the dust collector.
In addition, the enamel hair removing apparatus 1 scrapes and removes the enamel hair 63 (including a part that is likely to be peeled, whose adhesion is weak) immediately before peeling near the score 62 and the score 62. In the subsequent step of this step, the generation of the enamel hair 63 can be effectively prevented.
Further, the scraped enamel hair 63 is quickly recovered via the suction flow path 213 and the suction duct 5, so that the problem that the enamel hair 63 remains tangled with the brush 212 is avoided. be able to.

As described above, according to the enamel hair removing apparatus 1 of the present embodiment, the enamel hair 63 can be effectively removed, and the removal rate of the enamel hair 63 can be greatly improved. Further, it is not necessary to frequently replace and re-score the score cutter, so that the cost for re-polishing can be reduced and productivity can be improved.
In addition, although it is set as the structure which uses the segment-type roll brush 2 as a rotating brush, the structure of a rotating brush is not limited to the above, The brush (brush which can be rotated) of various structures is used. Can do.

[One Embodiment of Peeling Hair Removal Method]
Moreover, this invention is effective also as invention of the peeling hair removal method.
The peeling hair removal method of the present embodiment is a method of removing the enamel hair 63 from the corned beef 6 using the enamel hair removing apparatus 1 described above.
That is, the segment type roll brush 2 having the suction flow path 213 for sucking the enamel hair 63 is brought into contact with the corned beef can 6 by the magnet conveyor 11 conveying the corned beef 6, and the corned beef 6 The enamel hair 63 is scraped off, and the suction duct 5 sucks at least a part of the scraped enamel hair 63 through the suction channel 213 of the segmented roll brush 2.

  As a result, the score 62 on the side surface in the longitudinal direction of the corned beef 6 where the enamel hair 63 is likely to be generated is rubbed with the segmented roll brush 2, the enamel hair 63 is scraped off from the score 62, and the segmented roll brush 2 The enamel hair 63 can be sucked through the flow path 213 and the suction duct 5 and captured by a filter (not shown) of the dust collector.

In this case, the scraped enamel hair 63 is quickly collected via the suction flow path 213 and the suction duct 5, so that the enamel hair 63 remains tangled with the brush 212. Can be avoided. Further, since the brush 212 is in contact with the enamel hair 63 partially protruding by the suction of the suction channel 213 in a state where the enamel hair 63 is not tangled, the scraping performance can be improved. Therefore, the segment type roll brush 2 can effectively remove the enamel hair 63.

  In addition, the peeling hair removal method of the present embodiment preferably has a predetermined angle θ (in the present embodiment, from the angular position (horizontal position) where the brush 212 of the segmented roll brush 2 contacts the corned beef 6. The hair removal member 4 that contacts the brush 212 may be provided at a position on the rotation direction side by an angle θ of about 45 °. If it does in this way, when the member 4 for hair removal and the brush 212 will contact | abut, it will be in the state in which the enamel hair 63 in which the corned beef can 6 and the part were connected was pinched | interposed, and it will be effectively shredded from the corned beef 6 And the removal rate of the enamel hair 63 can be further improved.

  As explained above, according to the peeling hair removal method of this embodiment, the enamel hair 63 can be removed effectively and the removal rate of the enamel hair 63 can be significantly improved. Further, it is not necessary to frequently replace and re-score the score cutter, so that the cost for re-polishing can be reduced and productivity can be improved.

As mentioned above, although the preferable embodiment etc. were shown and demonstrated about the peeling hair removal apparatus and peeling hair removal method of this invention, the peeling hair removal apparatus and peeling hair removal method which concern on this invention are limited only to embodiment mentioned above. It goes without saying that various modifications can be made within the scope of the present invention.
For example, the peeling hair removal apparatus and peeling hair removal method of this invention are not limited to the case where it is used with respect to the corned beef 6. For example, although not shown in the figure, it is possible to avoid peeling hair generated in general when making a coated metal plate or a thermoplastic resin coated metal plate such as enamel hair generated from a flange or the like, a coat hair or a thermoplastic resin hair. It can be used as a countermeasure.
Also, the type of can is not particularly limited. For example, a three-piece can such as a welding can or a solder can, a drawn can for drawing a resin-coated metal plate, or a seamless combination of drawing ironing and stretching. It can also be applied to cans.
Furthermore, the can may be an empty can or an actual can after filling.
