That is, the height dimension L1 between the lower end portion 61c of the brush portion 61 and the transport surface 2c is shorter than the height dimension L2 of the container 10 (L1 <L2). Therefore, the container 10 to be transported is sandwiched between the lower end portion 61c and the transport surface 2c.

Further, in the first brush 60, the height dimension L3 of the lower end portion of the base portion 61a and the transport surface 2c is longer than the height dimension L2 of the container 10 (L3> L2). According to this, the transport of the container 10 is not hindered by the contact of the container 10 with the base 61a.

Further, the container 10 to be transported is positioned in the left-right direction by sandwiching the grip portion 15 between the belt conveyor portions 90R and 90L as described later. Since the grip portion 15 of the container 10 to be transported has a plurality of ribs formed in the circumferential direction to increase the strength, even if the grip portion 15 is sandwiched between the belt conveyor portions 90R and 90L, The container 10 has a structure that is not easily deformed.

The ends of the front side brushes 80a and 80a on the roller conveyor 2 side are the small convex portion 13c and the large convex portion 13d of the short side portion 13 of the container 10 which is conveyed in a state of being positioned in the left-right direction on the roller conveyor 2. It is arranged so as to be in contact with (not shown). That is, the front side surface brushes 80a and 80a can brush the small convex portion 13c and the large convex portion 13d related to the stacking of the containers 10. Further, the front side surface brushes 80a and 80a can also brush the burrs 100 protruding from the back surface 11a of the container 10 to the short side portions 13 and 13'.

Further, since the lower grip portion 15 is sandwiched between the belt conveyor portions 90R and 90L, the container 10 to be conveyed is brushed by brushing the front side surface brushes 80a and 80a provided above the belt conveyor portions 90R and 90L. The situation is easy to see.

Next, the deburring step, which is a mode for removing the burr 100, will be described in detail with reference to FIGS. 1 and 6 to 7.

First, as shown in FIG. 1, the container 10 is placed on the transport surface 2c of the roller conveyor 2 with the back surface 11a of the container 10 facing upward at the carry-in portion 2a. The roller conveyor 2 conveys the container 10 placed on the conveying surface 2c to the deburring unit 3.

As shown in FIG. 7A, when the container 10 transported by the roller conveyor 2 enters the deburring unit 3, the grip portion 15 is provided by the front end portions of the belt conveyor portions 90R and 90L which are the transport assisting means 9. Are in contact and pinched.

Further, due to the belt conveyor portions 90R and 90L, even if the short side portions 13 and 13'of the container 10 placed on the transport surface 2c are slightly tilted in the transport direction, the belt conveyor portions 90R and 90L of the container 10 By sandwiching the grip portion 15 from the left and right, the short side portions 13, 13'of the container 10 can be adjusted to be substantially parallel to the transport direction, so that brushing by the side brush unit 8 described later becomes easy.

As described above, the rollers 98, 98, ... Of the belt conveyor portions 90R, 90L are urged by springs toward the center side of the roller conveyor 2, so that the belt conveyor portions 90R, 90L hold the grip portion 15. It can be held by pressing from the left and right. Further, even if there is a slight difference in the left-right dimensions of the container 10, the container 10 can be stably sandwiched by the inner peripheral surfaces of the toothed belts 99 and 99 by the urging of the spring. Therefore, the transport assisting means 9 can reliably assist the transport of the container 10 by the roller conveyor 2.

As shown in FIGS. 6 (a) and 7 (a), the container 10 is conveyed toward the first brush 60 and the front side brush 80a. At this time, the first brush 60 is rotating in the direction M1, and the front side brushes 80a and 80a are rotating in the direction M2. That is, the lower end 61c of the first brush 60 and the ends of the front side brushes 80a and 80a on the roller conveyor 2 side are moving in the direction opposite to the transport direction of the roller conveyor 2.

As shown in FIG. 6B, when the container 10 reaches the first brush 60, the container 10 is sandwiched between the lower end portion 61c of the first brush 60 and the transport surface 2c in the vertical direction. The back surface 11a of 10 is brushed. Further, the lower end portion 61c of the first brush 60 also brushes the long side portions 12 and 12'near the back surface 11a and the burrs 100 formed near the back surfaces of the large convex portions 12d and 12d and the small convex portions 12c and 12c, respectively. (Not shown).

Further, since the lower end 61c of the first brush 60 is in a state of sandwiching the container 10 with the transport surface 2c, when the lower end 61c of the first brush 60 brushes the back surface 11a of the container 10, the first brush Since the lower end 61c of the 60 presses the container 10 against the transport surface 2c, the frictional force due to the movement of the lower end 61c of the first brush 60 can be reliably transmitted to the back surface 11a of the container 10.

As shown in FIG. 6A, the rotation direction of the first brush 60 is the direction M1, and the moving direction of the lower end portion 61c thereof is opposite to the conveying direction of the roller conveyor 2. Therefore, the first brush 60 The moving speed of the lower end portion 61c of the roller conveyor 2 and the transport speed of the roller conveyor 2 are added so that the relative speed between the two becomes faster than the transport speed of the roller conveyor 2 and the frictional force between the two is increased.

Further, since the bottom portion 11 of the container 10 is formed in a substantially lattice pattern, when the burrs 100 formed on the back surface 11a are removed by brushing the first brush 60, the removed burrs 100 are removed from the mesh of the bottom portion 11. Since it falls off, the removed burr 100 is unlikely to be accumulated in the first brush 60.

Further, since the bottom portion 11 of the container 10 is formed in a substantially grid pattern, by allowing the lower end portion 61c of the first brush 60 to enter the mesh, it is easy to bite into the root of the burr 100 formed on the back surface 11a. It has a structure that can reliably remove 100. Further, the burr 100 can be reliably removed by the synergistic effect of this characteristic and the increase in frictional force.

Since the rotation direction of the first brush 60 is the direction M1 at the lower end of the first brush 60, the thrust for transporting the container 10 is reduced, but the container 10 is sandwiched by the transport assisting means 9. Therefore, since the transport assisting means 9 assists the insufficient thrust, the transport speed of the container 10 does not slow down as much as the transport speed of the roller conveyor 2. That is, since the container 10 is conveyed at a constant speed, it is possible to suppress the occurrence of uneven brushing.

Next, as shown in FIG. 7A, the container 10 has a short side portion 13 near the back surface 11a after brushing with the first brush 60 while the grip portion 15 is sandwiched between the transport assisting means 9. , 13'to the front side brushes 80a, 80a and the rear side brushes 80b, 80b in this order.

Since the rotation direction of the front side surface brushes 80a, 80a and the rear side surface brushes 80b, 80b is the direction M2, and the moving direction of the end portion on the roller conveyor 2 side is opposite to the transport direction of the roller conveyor 2, the front side surface The moving speeds of the brushes 80a and 80a and the rear side surface brushes 80b and 80b and the transport speed of the roller conveyor 2 are added, and the relative speed between them becomes faster than the transport speed of the roller conveyor 2 and the frictional force between them increases. ..

Further, as shown in FIG. 7B, the vicinity of the side surfaces of the short side portions 13 and 13'is brushed twice in succession by the front side surface brushes 80a and 80a and the rear side surface brushes 80b and 80b. The burrs 100 that could not be removed by the side brushes 80a and 80a can also be removed by the rear side brushes 80b and 80b.

Further, as described above, since the back surface 11a of the container 10 has been brushed by the first brush 60, the burrs 100 formed on the back surface 11a are on the small convex portions 13c and 13c and the large convex portions 13d and 13d. May be pushed out. Such a burr 100 can also be brushed by the front side surface brushes 80a and 80a in the same manner as the burr 100 formed on each of the small convex portions 13c and 13c and the large convex portions 13d and 13d.

Since the front side brushes 80a and 80a and the rear side brushes 80b and 80b rotate in the direction M2, the thrust for transporting the container 10 is reduced. However, the container 10 has a belt conveyor portion 90R. Since it is in a state of being sandwiched by 90L, it does not slow down faster than the transport speed by the roller conveyor 2.

Next, although the direct illustration is omitted, the container 10 is on the short side after brushing with the front side brushes 80a and 80a and the rear side brushes 80b and 80b while the grip portion 15 is sandwiched by the transport assisting means 9. It is conveyed to the second brush 70 in order from the back surface 11a near the portions 13 and 13'. As a result, the back surface 11a of the container 10 that has not been brushed by the first brush 60 can be brushed.

The brushing mode of the second brush 70 is the same as the brushing of the first brush 60, as shown in FIGS. 6A and 6B.

Since the transport assisting means 9 transports the container 10 in a state of being sandwiched from the left and right until it passes through the first brush 60 to the second brush 70, the deburring means 5 prevents the transport of the container 10 from being stagnant. ..

Since the transport assisting means 9 sandwiches the container 10 from both sides, even if the container 10 receives brushing by each brush, the container 10 rotates horizontally on the transport surface 2c of the roller conveyor 2. It is deterred.

The deburring device 1 can remove the burrs 100 formed on the back surface 11a of the container 10 by brushing with the first brush 60 and the second brush 70 by passing the container 10 through the deburring unit 3, and the front surface. The burrs 100 formed on the short side portions 13 and 13'of the container 10 can be removed by brushing with the side brushes 80a and 80a and the rear side brushes 80b and 80b.

The container 10 that has been brushed by each brush is conveyed to the carry-out portion 2b by the roller conveyor 2. The container 10 conveyed to the carry-out portion 2b is washed by a washing machine (not shown).
[Modification 1]

So far, the deburring device 1 has described a deburring step for removing the burr 100, but an example having a deburring step which is performed before the deburring step in order to remove the burr 100 more reliably. , The synergistic effect will be explained in detail. Some aspects similar to the deburring step will be omitted or simplified.

In the burr alignment step, as in the deburring step, the container 10 is first placed on the transport surface 2c of the roller conveyor 2 in the carry-in portion 2a. The roller conveyor 2 transports the container 10 placed on the transport surface 2c to the deburring unit 3, and the transport assisting means 9 of the deburring unit 3 sandwiches the transported container 10.

As shown in FIGS. 8 (a) and 9 (a), the container 10 is conveyed toward the first brush 60 and the front side brush 80a. At this time, the first brush 60 is rotating in the direction P1, and the front side brushes 80a and 80a are rotating in the direction P2. That is, the lower end 61c of the first brush 60 and the ends of the front side brushes 80a and 80a on the roller conveyor 2 side are moving in the same direction as the transport direction of the roller conveyor 2.

Further, since the rotation direction of the first brush 60 is the direction P1 and the moving direction of the lower end portion 61c thereof is the same as the conveying direction of the roller conveyor 2, the moving speed of the lower end portion 61c of the first brush 60 and the roller conveyor The transport speed of 2 is subtracted, and the relative speed between the two becomes slower than the transport speed of the roller conveyor 2, and the frictional force between the two is reduced as compared with the configuration of FIG. Utilizing this, as shown in FIG. 8 (a), by brushing the burr 100 formed on the back surface 11a with an irregular orientation, the directions are substantially the same as shown in FIG. 8 (b). Can be aligned to.

Since the rotation direction of the first brush 60 is the direction P1, thrust in the transport direction is applied to the container 10, but the container 10 is in a state of being sandwiched by the transport assisting means 9. It does not accelerate faster than the transfer speed of the roller conveyor 2. That is, since the container 10 is conveyed at a constant speed, it is possible to suppress the occurrence of uneven brushing.

Next, as shown in FIG. 9B, the container 10 has the front side brush 80a in order from the portion where the brushing by the first brush 60 is completed while the grip portion 15 is sandwiched by the transport assisting means 9. Is transported to.

Since the rotation direction of the front side brushes 80a and 80a is the direction P2 and the moving direction of the end portion on the roller conveyor 2 side is the same as the transport direction of the roller conveyor 2, the roller conveyor 2 of the front side brushes 80a and 80a The moving speed of the end on the side and the transport speed of the roller conveyor 2 are subtracted, and the relative speed between the two becomes slower than the transport speed of the roller conveyor 2, and the frictional force between the two is reduced as compared with the configuration of FIG. It has become like. Utilizing this, as shown in FIG. 9A, by brushing the burrs 100 formed in the small convex portions 13c and 13c and the large convex portions 13d and 13d in irregular directions, FIG. 9 ( As shown in b), the orientations can be aligned in substantially the same direction.

Further, as described above, since the back surface 11a of the container 10 has been brushed by the first brush 60, the burrs 100 formed on the back surface 11a are on the small convex portions 13c and 13c and the large convex portions 13d and 13d. May be pushed out. Such a burr 100 can also be brushed by the front side surface brushes 80a and 80a in the same manner as the burr 100 formed on each of the small convex portions 13c and 13c and the large convex portions 13d and 13d.

Further, as shown in FIG. 9B, after brushing the front side brushes 80a and 80a, the rear side brushes 80b and 80b brush twice in succession, so that the front side brushes 80a and 80a are omitted. Even for the burrs 100 that could not be aligned in the same direction, the orientation can be aligned by the rear side brushes 80b and 80b.

Since the front side surface brushes 80a and 80a and the rear side surface brushes 80b and 80b are rotated in the direction P2, a thrust in the transport direction is applied to the container 10, but the container 10 is the transport assisting means 9. Since it is in a state of being sandwiched by the rollers, it does not accelerate faster than the transfer speed of the roller conveyor 2.

Next, although the direct illustration is omitted, the container 10 is on the short side after brushing with the front side brushes 80a and 80a and the rear side brushes 80b and 80b while the grip portion 15 is sandwiched by the transport assisting means 9. It is conveyed to the second brush 70 in order from the back surface 11a near the portions 13 and 13'. As a result, the back surface 11a of the container 10 that has not been brushed by the first brush 60 can be brushed.

In the deburring device 1, when the container 10 passes through the deburring unit 3, the direction of the deburring 100 formed in the vicinity of the back surface 11a transport direction of the container 10 by brushing with the first brush 60 and the second brush 70 is substantially uniform. By brushing with the front side brushes 80a and 80a and the rear side brushes 80b and 80b, the directions of the burrs 100 formed near the side surfaces of the short side portions 13 and 13'of the container 10 can be aligned substantially uniformly. it can.

The container 10 that has been brushed by each brush is conveyed to the carry-out portion 2b by the roller conveyor 2. The container 10 (container 10 for which the burr alignment step has been completed) transported to the carry-out unit 2b is collected.

In this way, when the deburring device 1 finishes the burr alignment step of the container 10, the rotation directions of the first brush 60 and the second brush 70, the front side brushes 80a and 80a, and the rear side brushes 80b and 80b are deburred. It is switched to the directions M1 and M2 which are opposite to the directions P1 and P2 which are the rotation directions of the alignment process. When the switching of each rotation direction is completed, the deburring step described above is performed. The orientation of the container 10 when placed on the transport surface 2c is the same as in the burr alignment step.

The burrs 100 formed on the back surface 11a of the container 10 are oriented in substantially the same direction in the burr alignment step, and the orientation faces the moving direction of the lower end portion 61c of the first brush 60, so that the burrs are surely aligned. The burr 100 can be reliably removed by brushing the lower end portion 61c of the first brush 60 by biting it into the root of the burr 100.

The burrs 100 near the side surfaces of the short side portions 13 and 13'are also aligned in substantially the same direction in the burr alignment process, and the directions are the roller conveyors of the front side brushes 80a and 80a and the rear side brushes 80b and 80b. Since the ends on the two sides face the moving direction, the burrs 100 can be reliably removed by surely biting each tip into the root of the burrs 100 and brushing.

The mode of brushing the second brush 70 in the deburring step after the deburring step is the same as the brushing of the first brush 60 in the deburring step after the deburring step.

As described above, the deburring device 1 can remove the burr 100 more reliably by performing the deburring step through the burr alignment step in order to remove the burr 100 of the container 10. ..
[Modification 2]

In the first modification, an example in which the container 10 is conveyed twice by the roller conveyor 2 to perform the deburring step and the deburring step has been described. However, the container 10 is conveyed once by the roller conveyor 2 and the burr alignment step is performed. The deburring process may be performed. For example, as shown in FIG. 10, the brush portion 161 of the first brush 160 and the brush portion 171 of the second brush 170 may be formed in a single continuous shape in the left-right direction. In this case, by rotating the first brush 160 and the second brush 170 in different rotation directions, the deburring step and the deburring step can be performed only by passing the container 10 through the deburring unit 3 once. Therefore, the burr 100 can be reliably removed in a short time. Further, since the brush portions 161, 171 are continuous in the left-right direction, brushing can be performed evenly.

Although the brush portions 161, 171 have been described as being formed as one continuous brush portion in the left-right direction, the present invention is not limited to this, and for example, a plurality of brush portions 61, 61, ... Or brush portions 71, 71, ... It may be arranged without a gap. In this embodiment, when any of the brush portions 61, 71 is worn or the like, it is only necessary to replace the worn portion, so that the cost related to the replacement can be suppressed.
[Modification 3]

In the first embodiment, an example in which the container 10 is conveyed once by the roller conveyor 2 to perform the deburring process has been described. However, the container 10 is conveyed twice by the roller conveyor 2, and in this case, the rollers are conveyed the first time and the second time. By changing the direction of the container 10 placed on the conveyor 2 by 180 degrees, the first deburring step and the second deburring step may be performed. In this case, even if the inclination of the burr 100 is different, it can be removed by either the first deburring step or the second deburring step.

In the present embodiment, the first brush unit 6 and the second brush unit 7 have been described as having the first motor 65 and the second motor 75, respectively, but the present invention is not limited to this, and the first brush unit 6 is not limited to this. Alternatively, one of the second brush units 7 may have a motor, and the other may follow the drive of one motor via a toothed belt or the like. In this embodiment, the number of members can be reduced.

Further, the brush portions 61, 61, 61 of the first brush 60 and the brush portions 71, 71 of the second brush 70 are arranged in the front-rear direction so as to be staggered in the left-right direction, but the present invention is not limited to this. , Only one first brush 160 extending in the left-right direction may be used.

Further, the front side brushes 80a and 80a and the rear side brushes 80b and 80b are designed to rotate in the same direction, respectively. For example, a pair of left and right front side brushes 80a and 80a rotate in the direction P2 and a pair of left and right brushes 80a and 80a. The rear side surface brushes 80b, 80b of the above may be rotated in the direction M2.

Further, the deburring unit 3 may be in a mode in which air blowing, water (including detergent or the like), or both are used in the deburring step and the deburring step. In this embodiment, the burr 100 peeled off from the container 10 adhering to the container 10 or the like can be reliably removed.

As described above, the deburring device 1 in the present embodiment includes the first brush 60 and the second brush 70 located above the transport surface 2c of the roller conveyor 2, and the lower end portion 61c of the first brush 60. The height dimension L1 of the lower end portion 71c of the second brush 70 and the transport surface 2c is shorter than the height dimension L2 of the container 10. Since the container 10 is sandwiched between the first brush 60 and the second brush 70 and the transport surface 2c of the roller conveyor 2, a sufficient frictional force is sufficiently applied to the container 10 from the first brush 60 and the second brush 70. It is reported that the burr 100 on the back surface 11a of the container 10 has a high removing power.

Further, since the container 10 has a box shape having an opening and is placed on the transport surface 2c of the roller conveyor 2 with the back surface 11a of the container 10 facing upward, the back surface 11a of the container 10 is placed during transportation and brushing. Easy to visually check the condition. Further, the burr 100 is likely to be formed on the back surface 11a of the container 10, which is particularly effective.

Further, the transport assisting means 9 that comes into contact with the short side portions 13 and 13'of the container 10 and assists the transport of the roller conveyor 2 in the transport direction is at least in the vicinity of the first brush 60 and the second brush 70, that is, the first brush 70. Since the brush 60 and the second brush 70 are provided below the first brush 60 from the front of the first brush 60 to the rear of the second brush 70, the first brush 60, the second brush 70, and the rollers are provided by the transport assisting means 9. The container 10 sandwiched between the conveyors 2 can be reliably conveyed. Further, since the transport assisting means 9 sandwiches the container 10 from both sides by the belt conveyor portions 90R and 90L, it is possible to suppress the acceleration of the transport of the container 10 in the vicinity of the first brush 60 or the second brush 70.

Although not shown, the first brush unit 6, the second brush unit 7, and the side brush units 8R and 8L are attached to the frame 4 so that the front-rear position, the left-right position, or the height position can be adjusted. According to this, even containers having different shapes can be brushed.

Although examples of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these examples, and any changes or additions within the scope of the gist of the present invention are included in the present invention. Is done.

For example, in the above embodiment, the bottom portion 11 of the container 10 has been described as being formed in a substantially lattice shape, but the present invention is not limited to this, and the bottom portion 11 may be in a substantially plate shape. Further, also in the long side portions 12, 12'and the short side portions 13, 13', each convex portion may not be formed, or may be simply a substantially plate-like one, or a grid-like mesh. It may be formed in a shape. That is, the shape of the container 10 may be a similar shape, and is not limited to the specific shape described in this embodiment.

The deburring device 1 has been described as a mode in which the roller conveyor 2 is provided as a conveyor device, but the deburring device 1 is not limited to this, and may be a belt conveyor and is not limited to the roller conveyor.

The transport direction of the roller conveyor 2 and the drive direction of the belt conveyor motor 95 of the transport assisting means 9 have been described as being constant, but the present invention is not limited to this, and even if the respective transport directions and drive directions can be reversed. Good.

The deburring means 5 has been described as a mode in which the first brush unit 6 and the second brush unit 7 are provided, but the present invention is not limited to this, and three or more brush units may be provided.

The first brush 60 and the second brush 70 have been described as having the same diameter of the brush portions axially supported by the respective shafts, but the present invention is not limited to this, and the lower end portions of the brush portions and the roller conveyor are conveyed. As long as the height dimension L1 between the surface and the surface is smaller than the height dimension L2 of the container, brush portions having different diameters may be used.

The cilia of the brush portions 61, 71 and the brush portion 81 have been described as being made of nylon containing an abrasive, but the present invention is not limited to this, and the cilia may be made of metal or other than nylon.

The side brush unit 8 has been described as a mode in which the front side brushes 80a and 80a and the rear side brushes 80b and 80b are provided, but the present invention is not limited to this, and the side brush unit 8 may have only one pair of left and right brushes, and a pair of left and right brushes. You may have three or more brushes.

The side brush unit 8 has been described as having the front side brushes 80a and 80a arranged in the front and the rear side brushes 80b and 80b arranged in the rear, but the present invention is not limited to this, and the left and right sides facing each other. It may have only a pair of side brushes.

Further, the side brush unit 8 may have a mode in which the brush portion is fixed to a pair of left and right shafts extending in the front-rear direction, and the brush portion rotates about the shaft. In this case, the brush portion may also extend to the front and back of a pair of left and right according to the shaft.

Further, although the side brush unit 8 has been described as a mode of brushing the short side portions 13, 13', the present invention is not limited to this, and the long side portions 12, 12'may be brushed.

Further, the width between the side brush units 8R and 8L may be adjusted according to the shape of the container 10, for example, the side brush units 8R and 8L are fixed to a plurality of elongated holes via bolts and nuts. , It may be possible to correspond to the long side portions 12, 12'and the short side portions 13, 13'of the container 10, respectively. The front side brush 80a is arranged behind the first brush 60 so as not to come into direct contact with the first brush 60, and the rear side brush 80b is directly attached to the second brush 70. The front side brush 80a and the rear side brush 80b are also separated from each other in the front-rear direction so as not to come into contact with each other. Due to these features, the side brush unit 8 does not come into contact with other brushes because the dimensions between the left and right sides are variable even if the dimensions between the side brush units 8R and 8L are variable.

Further, the front side brush 80a is provided so that the brush portion 81 is arranged substantially at the center of the upper and lower sides between the support members 88 and 88 on the front side of the pair of upper and lower support members 88 and 88 attached to the side frame 42.

Further, the rear side surface brush 80b is provided so that a cylindrical brush portion 81 is arranged substantially in the vertical center between the support members 88 and 88 on the rear side of the support members 88 and 88 described above. The rear side surface brush 80b is arranged so as to be separated from the second brush 70 in front of the second brush 70 so as not to come into direct contact with the second brush 70. Furthermore, the front side surface brush 80a and the rear side surface brush 80b are also separated in the front-rear direction so as not to come into contact with each other.

The front side brushes 80a and 80a and the rear side brushes 80b and 80b of the side brush unit 8 may be individually movable by being provided with motors.

The rollers 98, 98, 98 have been described as being in contact with the inner peripheral surface of the toothed belt 99 in a state of being urged by a spring toward the center side of the roller conveyor 2, but the present invention is limited to this. Instead, the urging means may be in another mode, such as being urged by flood control, or the toothed belt 99 may be urged toward the center side of the roller conveyor 2 depending on the mounting position. ..

The mode in which the container 10 is washed by a washing machine (not shown) after deburring by the deburring device 1 has been described, but the present invention is not limited to this, and the container 10 may be washed by the deburring unit 3. In this case, the rotation speed of the deburring means 5 can be slowed down, the material of the brush can be changed, and the like. Comparing this aspect with Patent Document 1, since the brush portions 61 and 71 are located above the transport surface 2c, the dirt removed from the container 10 falls due to gravity, and the brush itself is less likely to be soiled.

Further, in the mode of cleaning the container 10 by the deburring device 1, the mode of blowing air may be used. In this embodiment, the dirt removed from the container 10 can be blown off from the container 10 by blowing air on the dirt, so that the dirt can be prevented from adhering to the container 10 again. It should be noted that both cleaning and deburring are included in the concept of maintenance because the outside of the container 10 is prepared.

Further, in the mode of cleaning the container 10 with the deburring device 1, water (including detergent and the like) may be used. Comparing this aspect with Patent Document 1, in the first place, in the deburring device 1, the container 10 is placed and conveyed on the conveying surface 2c of the roller conveyor 2 with the opening of the container 10 facing downward. Therefore, water can flow down substantially uniformly from above from the back surface 11a of the container 10 to each grip portion 15, and since water is unlikely to collect in the container 10, it can be washed evenly. In addition, the above-mentioned air blowing may also be performed.

Further, unlike the transport container having long vertical dimensions in Patent Document 1, the container 10 in this embodiment is thin because the grip portion 15 and the like are formed so that the side surfaces do not substantially have parallel surfaces. It is a container. Therefore, when cleaning the container 10 of the present embodiment by the cleaning device of Patent Document 1, it is difficult to securely sandwich the grip portion 15 of the container 10 having a small contact area with the sandwiching belt, and the container 10 is conveyed on the rotating brush. The conveyed state of the container 10 is not stable, and the back surface of the container 10 is not sufficiently washed.
