Description

  TECHNICAL FIELD The present invention relates to a drum can ring processing apparatus and a drum can ring processing method for regenerating a drum can having a ring band on a cylindrical body into a straight can, and in particular, the ring band is formed by a pressure roller and a receiving roller. The present invention relates to a drum can ring processing apparatus and a drum can ring processing method that perform smooth processing of a ring zone by applying pressure from the inside and outside.

  A drum can is a container excellent in durability and fire resistance, and has many merits in use such as transportation and storage, and is used in various applications. There is a great demand for drums, and about 13 million new cans are produced annually.

  Usually, a drum can is formed with a ring of ridges on the body to increase the strength, but if there is no problem in strength depending on the application, a straight can is often used. There is a great demand for straight cans, which are used as ink containers for printing. However, the production amount of new straight cans is about 40,000 to 50,000, and the number is smaller than the total production amount.

  In addition, after the drum can has been used once, a recycle cycle is established that can be rehabilitated and reused, and the utilization rate of the recycled can in the market is also high. The number of recycled cans shipped is about 12 million annually, and many new cans are on the market, just like new cans.

  Along with environmental problems, there is a problem that the production of new cans is costly, and there is a demand for the reuse of straight cans as much as possible to increase the number of shipments. However, since the production amount of the original straight can is as small as 40,000 to 50,000 per year, there is a problem that the use of the straight can can be limited.

  Further, when a closed can having a top plate (upper lid) provided on the drum can is regenerated, there is a problem that if the top plate is removed and baking is performed, the length of the drum can in the longitudinal direction is shortened. Although there is a technique for stretching a drum can to make it the same length as a new can, there is a problem that the strength is weakened because the thickness of the drum can decreases when it is stretched.

  The drum can 80 to be reclaimed in the present invention is constituted by a top plate provided with a filling port, a base plate facing the top plate, and a cylindrical body 82 closed by the top plate and the base plate. In addition, open cans without top plates are also included. An annular zone 84 is provided on the drum body 82.

  As shown in FIGS. 1 and 2, the drum ring zone processing apparatus 10 of the present invention includes a pressure roller 20, a receiving roller 30, an axial positioning roller 40, a radial positioning roller 50, and an auxiliary roller 22. The heating device 24 and the guide roller 60 are provided.

  The axial positioning roller 40 is a roller that determines the position of the drum can in the axial direction. As shown in FIG. 1, in a state where the drum can 80 is on its side, the peripheral wall of the axial positioning roller 40 is in contact with a part of the circumference of the body 82 on the top plate side or the base plate side. Although not shown, when the drum can 80 is in a vertical state, the drum can 80 is provided so as to abut on a part of the circumference on the top plate side or the base plate side located above.

  The radial positioning roller 50 is a roller that determines the radial position of the drum can. As shown in FIG. 2, the drum can 80 is provided so as to come into contact with the peripheral wall of the body 82. The radial positioning roller 50 is composed of a pair of rollers made up of two rollers, and the drum 82 can be positioned by sandwiching the body 82 at two points.

The pressure roller 20 is a roller that presses the annular zone 84 of the ridge provided on the body 82 from the outer surface of the body. In this embodiment, the pressure is applied by a pressure air cylinder 72 provided above the pressure roller 20.
As shown in FIG. 1, the pressure roller 20 may have a structure in which one single roller is provided. However, the pressure roller 20 may be a pair of pressure rollers including two rollers. By providing a pair of pressure rollers for one annular zone, the applied pressure can be increased and the processing time of the annular zone can be shortened. Further, a single or a pair of pressure rollers can be provided at one place to move the drum can and process the two annular zones provided on the body 82. Further, as shown in FIG. 1, it is possible to adopt a structure in which two pressure rollers are provided in accordance with the number and position of the annular zones.

The receiving roller 30 is a roller that receives pressure from the pressure roller 20 from the inside of the body 82. The receiving roller 30 is inserted into the drum body body 82 from which the top plate or the base plate is removed, and has a structure in which the peripheral wall of the receiving roller 30 abuts against the inner side surface of the body 82 when pressed.
In the present embodiment, one receiving roller 30 is provided as a roller that covers the range of the annular zone 84, but a plurality of receiving rollers 30 are provided corresponding to the number of annular zones 84 so as to correspond to the pressure roller 20. It is also possible to provide a structure.

  Although the present embodiment shows a structure in which the zonal processing is performed in a state where the drum can is tilted sideways, the axial positioning roller 40 and the radial positioning roller 50 are disposed on the upper side and the side surface of the drum can with the drum can in the vertical state. It is also possible to adopt a structure that positions and pressurizes the annular zone.

The auxiliary roller 22 is a roller that presses the annular zone including the annular zone and the periphery of the annular zone after the annular zone processing by the pressure roller 20. The auxiliary roller 22 is a substantially spherical roller, and can have a structure capable of freely rotating the ring surface of the drum can 80 in all directions. With a structure that can rotate not only in the circumferential direction of the drum can but also in the longitudinal direction of the drum can, the wrinkles and deviation of the annular portion of the body 82 can be eliminated and a smooth straight can can be obtained.
In this embodiment, a spherical auxiliary roller 22 is provided at the tip of the cylinder. The auxiliary roller 22 is operated by an air cylinder within the range of 0 mm to 50 mm in the longitudinal direction of the drum can.

By heating the annular zone while rotating the drum can, it returns to the state before the iron molecules are processed, and the annular zone can be processed smoothly.
In this embodiment, heating is performed by acetylene gas from the lateral direction of the body 82 located above the lying drum can 80. One or two heating devices 24 can be provided in accordance with the annular zone. The position of the heating device 24 is not limited to the position shown in FIGS. 2 and 3, and may be any position that can heat the annular zone 84 in the vicinity of the annular zone portion. By stretching the annular zone 84 heated by the heating device 24 while being pressed by the auxiliary roller 22, a smoother straight can can be manufactured.

Next, the drum cannula processing method of the present invention will be described in detail.
The drum 80 is moved to the drum ring zone processing apparatus 10 with at least one of the top plate or the main plate removed for the regeneration process.
As shown in FIGS. 1 and 2, the moved drum can is placed on a guide roller 60 provided at the lower portion of the drum can ring processing apparatus.

  The placed drum can 80 has its longitudinal position determined by abutting the axial positioning roller 40 on a part of the circumference of the body 82 on the top plate or the main plate side. In addition, a set of radial positioning rollers 50 is brought into contact with the body 82 from above, thereby determining the radial position and positioning the drum.

  After the position of the body 82 is determined by the axial positioning roller 40 and the radial positioning roller 50, the annular zone 84 of the drum can is pressed by the pressure roller 20 and the receiving roller 30, and subjected to a deformation process. The receiving roller 30 is inserted into the drum 82 body 82 and is inscribed in the inner surface of the body 82. The pressure roller 20 comes into contact with the outer surface of the body 82 from the outside of the drum can, and the annular zone 84 is pressed from the inside and outside of the drum can body 82 with the rotation of the drum can to be deformed flat.

The drum 80 having the ring zone 84 pressed by the pressure roller 20 is further pressed by the auxiliary roller 22 around the ring zone and the ring zone.
As shown in FIG. 3, the pressing process by the auxiliary roller 22 may be configured to be performed by a smoothing ring zone processing apparatus provided with a pressure roller 20 and another auxiliary roller 22. The smoothing apparatus includes an auxiliary roller 22 and a heating device 24 instead of the pressure roller 20 or the radial positioning roller 50. By using in combination with the drum can ring processing apparatus, it is possible to perform ring processing of a large number of drum cans in a short time.
The auxiliary roller 22 has a substantially spherical shape and can be rotated not only in the circumferential direction of the drum can 80 but also in the longitudinal direction. By pressing the auxiliary zone 22 while rotating the annular zone in the circumferential direction or the longitudinal direction within a range of 0 mm to 50 mm, the annular zone 84 is made smooth. The receiving roller 30 is inserted into the drum can 80, and the pressure generated by the rotation of the receiving roller 30 and the auxiliary roller 22 smoothes wrinkles and shifts remaining on the drum can 80 after being pressed by the pressure roller. .

  In addition to the pressing process by the auxiliary roller 22, the annular zone is heated by the heating device 24. By pressing the annular zone 84 in a heated state, the processing time can be shortened and a smoother can can be obtained.
