The top plate 8 is provided with an exhaust base 11 and an injection base 13. A part of the dirt wiping device 4 shown in FIG. 1 is a cross section taken along the line II in FIG.

FIG. 3 is an enlarged sectional view showing the chime 12 of the drum 2. The chime 12 is formed by mutually joining the upper end edge of the body 6 and the outer peripheral edge of the top plate 8 by tightening with a seamer (winding machine) with a filler interposed. A chime 14 similar to the chime 12 is also formed from the lower end edge of the body 6 and the outer peripheral edge of the main plate 10.
The dirt wiping device 4 is generally composed of a rotating mechanism 16 that rotates the drum 2 in the body circumferential direction X, and a wiping unit 18 that wipes dirt in an area including the upper chime 12.

  Here, as shown in FIG. 3, the region including the chime 12 in the drum 2 for wiping off the dirt by the wiping unit 18 is the body 12 a that is the body 6 near the chime 12, and the body height direction Y of the drum 2. The inner edge 12b of the chime 12 is located on the body 6 side, the outer edge 12c of the chime 12 is located on the opposite side of the body 6 in the body height direction Y, and the body diameter direction Z of the drum 2 As a region including a top portion 12d that is the outer peripheral edge of the chime 12 as viewed, and an inner peripheral portion 12e that is located in the range from the inner peripheral edge 12e1 of the chime 12 to the upper surface (plate surface) 8a of the top plate 8 when viewed in the body radial direction Z. It is prescribed.

  The rotating mechanism 16 holds the drum 2 between the upper surface 8a of the top plate 8 and the lower surface (plate surface) 10a of the base plate 10, and a pair of upper and lower clamps (supporting portions) 20 and 22 each having a disk shape. It has. Rotating shafts 20a and 22a are connected to the centers of the clamps 20 and 22, respectively. Further, as shown by an arrow, the rotating shaft 20a is configured to be movable up and down in the body height direction Y by a lifting mechanism (not shown).

  The drum can 2 is placed on the clamp 22, the clamp 20 is lowered to sandwich the drum can 2, and a rotational force is applied to the rotary shaft 22 a from a drive unit (not shown), whereby the drum can 2 is rotated in the body circumferential direction X. The Further, a substrate 20b that rotatably supports the clamp 20 and the rotating shaft 20a is fixed to the upper side of the clamp 20. Four guide rollers 24 are fixed to the outer periphery of the substrate 20b with a lift cylinder 24a apart.

  These guide rollers 24 include flange portions 24b that are rotatably supported. Each flange portion 24 b is positioned between the clamp 20 and the inner peripheral edge 12 e 1 of the chime 12. Each flange portion 24b is positioned so as not to contact the upper surface 8a of the top plate 8 and the chime 12 even when the guide roller 24 is lowered by the elevating cylinder 24a, and at a position where the clamp 20 is separated from the inner peripheral edge 12e1. Guidance is made to contact the top surface 8a of the top plate 8. Although not shown, a wiping unit similar to the wiping unit 18 may be provided on the lower chime 14 side.

  The wiping unit 18 includes a feeding mechanism 28 for a towel 26 which is a dirt wiping material for the chime 12, a winding mechanism 30 for winding the towel 26 after the chime 12 is wiped, a holding mechanism 32 for gripping and holding the towel 26, and a feeding mechanism. The structure includes a pressing mechanism 34 that presses and contacts the towel 26 conveyed between the mechanism 28 and the winding mechanism 30 to the region including the chime 12 of the drum 2. The wiping unit 18 can move these mechanisms integrally or in conjunction.

  The delivery mechanism 28 is generally configured by, for example, four roll shafts 28a. The roll towel 26a is fed to the delivery mechanism 28 by inserting the core cavity of a roll body of a commercially available roll towel 26a (for example, 210 mm wide, 18 m roll) in which the towel 26 is wound on the roll shaft 28a farthest from the drum 2. Set. The delivery mechanism 28 is a so-called pinch roll, and the edge of the towel 26 is alternately passed between the remaining roll shafts 28a, and at least one of the roll shafts 28a is rotated by a drive unit such as a motor with brake (not shown). Thereby, the towel 26 is pulled out from the roll towel 26a by the frictional force with each roll shaft 28a.

Then, the towel 26 is sent out in the conveying direction A along the rotation direction of the drum can 2 toward the vicinity of the chime 12 on the drum can 2 side in a posture in which the width direction thereof is the body height direction Y of the drum can 2.
The winding mechanism 30 is schematically configured from, for example, three roll shafts 30a. Similarly to the delivery mechanism 28, the take-up mechanism 30 alternately passes the edge of the towel 26 between the remaining roll shafts 30a. Then, by rotating at least one of the roll shafts 30a by a driving unit such as a motor with a brake (not shown), the towel 26 winds up the towels 26 fed from the feed mechanism 28 by the frictional force with each roll shaft 30a. Thus, a wound body of the used roll towel 26b is formed.

  By making the winding speed of the towel 26 of the winding mechanism 30 slightly higher than the feeding speed of the towel 26 of the feeding mechanism 28, an area including the chime 12 described above is provided between the feeding mechanism 28 and the winding mechanism 30.

It consists of and. By supporting the towel 26 sandwiched between the upper and lower chucks 32a and 32b, the towel 26 can be prevented from slipping off from the roll shafts 28a and 30a even by the operation of the pressing mechanism 34. Note that the holding mechanism 32 may be configured by only the two upper chucks 32a.

  The pressing mechanism 34 includes an inner pad 36 disposed on the inner side of the wiping area 26 c, that is, on the drum can 2 side, and an outer edge pad 38 and an inner edge pad disposed on the outer side of the wiping area 26 c, that is, on the opposite side of the drum can 2. 40. The outer edge pad 38 and the inner edge pad 40 are disposed at a position completely displaced in the transport direction A in the wiping area 26c, and the outer edge pad 38 is the inner edge pad in the body height direction Y. It is arranged slightly above 40. Further, advance / retreat cylinders 36a, 38a, 40a, which are actuators such as air cylinders and oil cylinders, and elevating cylinders 36b, 38b, 40b are respectively connected to the pads 36, 38, 40 via rods. .

  Here, the delivery mechanism 28 and the upper chuck 32 a and the lower chuck 32 b disposed on the delivery mechanism 28 side of the holding mechanism 32 are fixed to the small substrate 42. On the other hand, the winding mechanism 30 and the upper chuck 32 a and the lower chuck 32 b arranged on the winding mechanism 30 side of the holding mechanism 32 are fixed to a small substrate 44 that is separate from the small substrate 42. In the present embodiment, the small substrate 44 is provided with an advance / retreat mechanism, and by driving the drive unit of this advance / retreat mechanism, the small substrate 44 approaches or separates from the small substrate 42 as indicated by an arrow in FIG. And slidable along the conveying direction A. However, the present invention is not limited to this, and it is sufficient that at least one of the small substrates 42 and 44 is configured to be slidable along the transport direction A.

  The forward / backward movement / lifting cylinders 38a, 38b of the outer edge pad 38 and the forward / backward movement / lifting cylinders 40a, 40b of the inner edge pad 40 are fixed to the large board 46 disposed below the small boards 42, 44. Has been. A small substrate 44 is also fixed to the large substrate 46, and the small substrate 42 is also fixed to the large substrate 46 so as to be slidable along the transport direction A. The large substrate 46 is provided with an advancing / retreating mechanism, and the wiping unit 18 is configured to be slidable integrally in the advancing / retreating direction B with respect to the drum can 2 by driving a drive unit of the advancing / retreating mechanism. An air blow nozzle 48 is fixed on the large substrate 46 between the advance / retreat cylinders 38a, 38b of the outer edge pad 38 and the advance / retreat cylinders 40a, 40b of the inner edge pad 40.

Hereinafter, the operation of the dirt wiping device 4 will be described with reference to FIGS. 4 to 11. FIGS. 4 to 11 are schematic diagrams partially omitting the description of the detailed parts in order to mainly explain the operation of the dirt wiping device 4 in an easily understandable manner.
First, as shown in FIG. 4, the wiping area 26 c of the towel 26 is brought close to the area including the chime 12 by sliding the large substrate 46 in the direction of the arrow approaching the drum 2.

  Next, as shown in FIG. 5, the small substrate 42 is slid in a direction to approach the small substrate 44 to be loosened in the center of the upper end of the wiping region 26 c to form a slack region 26 d of the towel 26. At this time, air is blown from the air blow nozzle 48 to the slack area 26d from the opposite side of the wiping area 26c to the drum 2 to guide the slack area 26d to a position where the slack area 26d is covered by the inner peripheral portion 12e of the chime 12.

Next, as shown in FIG. 6, the drum 20 is clamped by the clamps 20 and 22 by lowering the clamp 20 in the direction of the arrow.
At this time, as shown by a broken line in FIG. 7, the clamp 20 covers the inlet 13, thereby preventing foreign matter from entering the inlet 13 when the dirt wiping device 4 is operated. In addition to the lowering of the clamp 20, each guide roller 24 is also lowered by the operation of the elevating cylinder 24a.

  Since the guide roller 24 is not in contact with the upper surface 8a of the top plate 8 and the chime 12, the guide roller 24 is prevented from being contaminated with dirt including lubricating oil from the chime 12. Further, after the clamps 20 and 22 hold the drum 2, the guide roller 24 is raised and returned to the original position by the operation of the elevating cylinder 24 a.

  On the other hand, as shown by a broken line in FIG. 8, as the clamp 20 is lowered, the clamp 20 covers the exhaust base 11 to prevent foreign matter from being mixed into the exhaust base 11 when the dirt wiping device 4 is operated. In addition, when the label which covers the exhaust nozzle 11 is stuck on the exhaust nozzle 11, there exists a possibility that this label may peel off by the contact of the slack area | region 26d of the towel 26. FIG. However, when the clamp 20 covers the exhaust base 11, this label peeling can be suppressed.

  Further, as shown in FIG. 8, along with the lowering of the clamp 20, the inner pad 36 is also lowered by the operation of the elevating cylinder 36b, and is pressed against the upper surface 8a of the top plate 8 via the slack area 26d. Next, the inner pad 36 is pressed and brought into contact with the inner peripheral edge 12e1 of the chime 12 through the slack area 26d by the operation of the advance / retreat cylinder 36a.

  The inner pad 36 is positioned on the inner side of the chime 12 when viewed in the body radial direction Z of the drum 2 from the outer edge 12c positioned on the opposite side of the body 6 of the chime 12 when viewed in the body height direction Y of the drum 2 The slack region 26d can be pressed and brought into contact with the inner peripheral portion 12e of the chime 12 across the upper surface 8a of the top plate 8 through the inner peripheral edge 12e1.

  Specifically, the inner pad 36 is formed from a low-repulsion material such as urethane or felt having an L shape in cross section, extends in the body radial direction Z of the drum 2, and protrudes to press the slack area 26 d against the outer edge 12 c. A portion 36c, and a flat portion 36d that is bent substantially vertically downward from the protrusion 36c and extends in the body height direction Y of the drum 2 and presses the slack region 26d against the inner peripheral portion 12e of the chime 12. .

On the other hand, as shown in FIG. 9, when the inner pad 36 presses and contacts the slack region 26 d with the inner peripheral portion 12 e of the chime 12, the outer edge pad 38 and the inner edge pad 40 are also pressed and contacted with the chime 12. The
Specifically, as shown in FIG. 10, the outer edge pad 38 is formed from the same material as the inner pad 36 having an L-shaped cross-sectional view, extends in the body radial direction Z of the drum 2, and the outer edge 12 c. A protrusion 38c that presses the slack region 26d, and a flat portion 38d that is bent substantially vertically downward from the protrusion 38c and extends in the body height direction Y of the drum 2 and presses the slack region 26d against the top 12d of the chime 12. It consists of and. The outer edge pad 38 is pressed and contacted from the outer edge 12c to the top 12d of the chime 12 when viewed in the body height direction Y of the drum 2.

  Further, as shown in FIG. 11, the inner edge pad 40 is formed of the same material as the inner pad 36 having an I-shaped cross section, extends in the body radial direction Z of the drum can 2, and has an inner edge 12b. And a vertical surface 40d that extends in the body height direction Y of the drum 2 and presses the slack area 26d against the body 6 in the vicinity of the chime 12. The inner edge pad 40 is pressed and contacted from the body 6 through the inner edge 12b of the chime 12 to the top 12d as seen in the body height direction Y of the drum 2.

  Each pad 36, 38, 40 enters the corner or arc surface formed in the chime 12 while being deformed via the slack region 26 d in accordance with the pressing contact with the chime 12, and matches the corner or arc surface. In this state, as shown in FIG. 8, by rotating the drum can 2 in the body circumferential direction X by the rotation mechanism 16, the region including the chimes 12 can be wiped without being left behind by the towel 26.

  As described above, in this embodiment, the seamer lubricating oil is sufficiently sprayed to perform chime processing that guarantees the most important content leakage prevention in the drum 2, and then the drum can 2 is wiped by the drum can dirt wiping device 4 of the present invention. Both the productivity and quality performance of the drum can 2 can be improved by automatically removing the chimes 12 and the vicinity thereof. Specifically, it is possible to eliminate the wiping work by the worker who becomes heavy labor, and it is possible to prevent the dirt from being left unwiped and to prevent the exterior failure of the drum can 2.

  Further, since the amount of seamer lubricating oil can be properly supplied without worrying about dirt adhering to the chime 12 and the vicinity thereof, the chime processing that guarantees the most important content leakage prevention in the drum can 2 is realized. While being able to provide high quality products.

  In particular, in the present embodiment, the slack area 26d is formed while preventing the towel 26 from sliding off by the holding mechanism 32, and the slack area 26d is pressed into contact with the area including the chime 12 so that the towel 26 contacts the chime 12. Can be in surface contact. For this reason, the dirt of the drum can 2 can be wiped off efficiently while using the wiping area 26c of the towel 26 over a wide range.

In addition, by blowing air from the air blow nozzle 48 to the slack area 26d, the slack area 26d can be reliably guided to the inner peripheral portion 12e of the chime 12, and can be wiped without wiping up to the inner peripheral portion 12e of the chime 12. it can.
Moreover, since the positioning of the clamp 20 with respect to the top plate 8 can be automatically performed by providing each guide roller 24, the clamp 20 interferes with the wiping remaining on the inner peripheral portion 12e of the chime 12. Absent.

  In addition, since the guide rollers 24 are lifted and retracted after the clamp 20 is positioned, the wiping of the inner peripheral portion 12e of the chime 12 by the slack area 26d is not hindered. In addition, since each guide roller 24 is adjusted so as not to contact the drum 2 when lowered, the oil stain of the drum 2 adheres to each guide roller 24, and each guide roller 24 stains the drum 2. It can be stopped.

  Further, since the clamp 20 covers the exhaust base 11 and the injection base 13, foreign matters are prevented from entering the exhaust base 11 and the injection base 13 when the dirt wiping device 4 is operated. Further, when a label that covers the exhaust base 11 is attached to the exhaust base 11, the clamp 20 covers the exhaust base 11, so that peeling of the label can be suppressed.

The present invention is not limited to the above embodiment, and various modifications can be made.
Specifically, in the dirt wiping device 4 of the above embodiment, the towel 26 sent out from the roll towel 26a is used as a wiping material, but the wiping material is not limited to this.
Moreover, you may use the wiping material impregnated with the cleaning agent which consists of water, an organic solvent, etc. Thereby, the dirt removal efficiency of the chime 12 and the vicinity thereof is improved, and the life of the wiping material can be extended. However, when an organic solvent is included in the cleaning agent, it is necessary to take measures under the Industrial Safety and Health Law and Fire Service Law regarding explosion-proof measures.

Further, the number of pads used in the pressing mechanism 34 of the above embodiment and the shape of the pads are not limited to this. Specifically, the shape may be any shape as long as the dirt attached to the corners and the arc surface formed in the region including the chime 12 can be wiped off without being left behind.
Moreover, in the said embodiment, although the wiping area | region 26c is shifted to the conveyance direction of the towel 26 for every drum can 2 conveyed, wiping of dirt is performed, but the wiping area | region is moved up and down by the raising / lowering mechanism which is not shown in figure. 26c may be shifted up and down to wipe off dirt. In this case, the consumption of the towel 26 can be suppressed, which is preferable.

  Moreover, in the said embodiment, although the dirt wiping apparatus 4 of the sealed drum can 2 was demonstrated, this dirt wiping apparatus 4 is applicable also to an open type drum can. The open-type drum can includes a canopy that can be opened and closed instead of the top plate 8. In this case, instead of the outer edge pad 38 described above, a pad corresponding to the shape of the outer peripheral edge of the canopy is disposed in the wiping unit 18 so that this part can be wiped off. In this case, since the chime 14 similar to the sealed type is formed on the base plate 10 side, dirt on the chime 14 can be wiped off by the lower wiping unit.
