DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of packaging a cylindrical body in which a metal band such as a steel band is wound in a coil shape and an outer package for protecting the outer surface is wound around the cylindrical surface. More particularly, the present invention relates to a method and an apparatus for wrapping a cylindrical body suitable for packaging a cylindrical body in multiple layers with a plurality of types of exterior sheets having different functions.

[0002]

2. Description of the Related Art For example, a large cylindrical body such as a steel plate coil of a car or a tin plate for a can has to be separately packaged on its outer periphery, both end surfaces and the inner periphery of a hollow portion. Are supplied from different sources to different working locations. Usually, the cylindrical body to be packaged is sequentially transported on a substantially horizontal transport line perpendicular to the axis thereof, and for example, the inner packaging work position, the outer packaging work position, and the end face packaging work position are spaced along the transport line. Are sequentially arranged. Among these, conventionally, the outer peripheral wrapping sheet is fed from a base paper roll which is arranged on the transport line in the ceiling space above the cylindrical body to be wrapped so that the center line of the transport line and the center line of the wrapping sheet substantially coincide with each other, and the outer peripheral wrapping sheet is provided. Arrangements have been developed that can be supplied and wound onto a surface.

[0003] In this case, the cylinder to be wrapped entering the transport line is not necessarily of a fixed surface length (length in the axial direction), and usually needs to handle cylinders of various surface lengths. Base paper rolls of various widths must be prepared accordingly. However, it is not easy to lift a number of heavy and bulky base paper rolls into the ceiling space and store them so that they can be switched and used at any time.

Further, the packaging sheet fed from the base paper roll in the ceiling space is directly supplied to and wound around the peripheral surface of the cylindrical body to be packaged. In this case, the cylindrical body having a different surface length is placed at the packaging position. When it enters, the time required to switch to a base paper roll having a different width takes a long time, so that the start of packaging is delayed, and the overall packaging capacity is reduced. In order to solve such a problem, in Japanese Patent Application Laid-Open No. 60-148422, several kinds of wrapping sheet supply sources are installed on a floor surface which is substantially at the same height as the conveying line of the cylindrical body to be wrapped. A surface winding device for a cylindrical body which receives predetermined lengths of various outer peripheral wrapping sheets, winds them around itself, carries them onto a cylindrical body to be wrapped located on a transport line, and unwinds and winds the wrapping sheets of the predetermined length onto the cylindrical body. Has been proposed.

That is, this means is a traveling means which can reciprocate between an outer peripheral wrapping position set on a conveying line of a cylindrical body to be wrapped and a wrapping sheet supply portion having a center line parallel to the conveying line. A swing frame supported on the traveling means so as to be able to swing coaxially with the axis of the cylindrical body, and a slide mounted so as to be able to slide in the radial direction of the cylindrical body on the swing frame. A frame, a set of an unwinding roll and a holding roll, which cantilever is suspended on the sliding frame substantially parallel to the axis of the cylindrical body and can rotate freely, and a guide plate for bridging between the rolls; When the set of unwinding roll, holding roll, and guide plate starts to rotate relative to the cylindrical body, the starting sheet pressing means for holding the vicinity of the winding sheet winding start end against the surface of the cylindrical body, Even roll has a configuration that is connected to the pressure means so as to pivot about the unwinding roll.

Further, Japanese Patent Publication No. 3-69766 discloses that
2. Description of the Related Art There has been proposed a method of bonding a winding end of a cylindrical package, in which the winding end (the rear end of the sheet) of the packaging sheet is adhered to the cylindrical body at the same time when the winding of the packaging sheet is completed. This is because it is necessary to fix the winding end of the packaging sheet on the cylindrical body by bonding or the like when wrapping the packaging sheet around the outer periphery of the cylindrical body such as a steel sheet coil, so that the fixing work is continuously performed. It is intended to be carried out easily and always in a short time as part of an automatic process. The outline of the winding end bonding method is as follows. Before starting the packaging, an adhesive tape is adhered to one end of the packaging sheet (the end to be the winding end later), for example, about half of the tape width, and at the start of winding, the packaging sheet is From the opposite end to the one end, the wrapping sheet is pressed and wound on the wrapped cylindrical body sequentially from the one end. The pressing operation is continued until about half of the width of the adhesive tape is adhered on the cylinder. Thus, the bonding and fixing of the winding end is instantaneously terminated at the same time as the completion of the winding. In this case, a temporary winding roll having a surface with a good peeling property with respect to the adhesive tape and capable of rotating forward and backward is disposed so as to be able to reciprocate between a position immediately above the cylindrical body to be wrapped and a side position. At one position, the above-mentioned one end of the packaging sheet is temporarily bonded on the temporary winding roll with an adhesive tape using a half of the tape width. Thereafter, the temporary winding roll is moved onto the cylindrical body to be wrapped, and the opposite end of the above-mentioned one end of the wrapping sheet (winding start end)
Is pressed and held temporarily on the cylindrical body, and a set with a pressing roll connected to the temporary winding roll is rotated around the cylindrical body peripheral surface, and the packaging sheet is rewound from the temporary rotating roll that rotates in the reverse direction and the packaging sheet is unwound. The temporary holding is released when the pressing position close to the surface is approached, and the temporary holding is released, and finally the adhesive tape is peeled off from the temporary winding roll by a tensile force acting on the temporary adhesive portion at the winding end, and the cylindrical It moves onto the body and is adhered onto the cylindrical body by the pressing roll.

Further, Japanese Utility Model Publication No. 5-35048 discloses that
Instead of accommodating a plurality of large wrapping paper rolls in a ceiling space or the like of a transport line, a wrapping paper supply apparatus has been proposed in which a plurality of wrapping paper rolls can be arbitrarily selected in a turret-type rotating annular body. . This includes a turret type base paper supply device capable of being discharged from a web discharge position set at a fixed height position, a cutter for cutting a base paper web sent from the base paper supply device into a predetermined length, and a cutter for cutting the base paper web into a predetermined length. Is provided with a width cutting mechanism for cutting the edge of the base paper web sent to the subsequent stage so that the base paper web has a predetermined width, and can supply a predetermined length and a predetermined width of a packaging base paper selected from a desired packaging base paper roll. It is like that.

The sheet winding / rewinding roll 120 is freely rotatable in both forward and reverse directions on a support shaft extending from the outer end of the sliding frame 117. Further, the sheet winding / rewinding roll 120 and the holding roll 121 are made of the steel coil 1.
Is connected to a cylinder 124 mounted on a sliding frame 117 so as to be able to pivot around the shaft, and is mounted so as to freely rotate around its own axis.

The coil lifter 3 includes a cylinder 125
Thereby, it can be moved in a direction orthogonal to the coil transfer line 2. Further, an inner diameter support rod 3a of the steel plate coil 1 is horizontally protruded from a vertical surface of the lifter frame 3b, and the cylinder 12 extends along the vertical surface of the lifter frame 3b.
6 is driven up and down. Then, the inner diameter support rod 3a is inserted into the inner diameter of the steel sheet coil 1 transported by the transport table 2a of the coil transport line 2, and
The steel sheet coil 1 is lifted and supported.

Hereinafter, the operation of the multiplex packaging apparatus constructed as described above will be described in which the rust-proof paper Sa and the board S
This will be described by taking as an example a case in which b is wound in order and packaged in two layers. In this case, the order of temporary winding on the sheet winding / rewinding roll 120 is as follows: first, the board Sb, and the rust-proof paper Sa
And First, based on the coil information, the rolls A ₁ to A _{1 of the} original packaging sheet held in the unreel section 4.
The roll A ₁ of the board Sb is selected from A ₆ , and the leading end of the board Sb (which becomes a winding end E _END during packaging) is supplied to the paper connecting section 5.

In the paper passing connection section 5, the width cutting cutters 21 and 22 are set in advance to the width of the steel sheet coil 1 according to the coil width information, and the endless belt mechanism 23,
At 24, trimming is performed while sending out the board Sb. During this process, the apparatus temporarily stops, and the rear end of the board Sb is cut by the cutter 17. Thereafter, the apparatus is restarted to trim the remaining portion of the board Sb, and the wrapping sheet S having a size corresponding to the circumferential length and width of the steel sheet coil 1 to be wrapped is taken up at the subsequent stage. It is fed to just below the roll 120 of the take-up and wrapping device 6 and stopped [FIG.
(A)].

Next, the traveling frame 39 of the adhesive tape adhering device 30 is driven by a motor or the like (not shown) and moved along the guide 41 in the length direction of the sheet take-up / rewind roll 120. Then, once the vehicle travels to a predetermined position, the vehicle is temporarily stopped. After the stop, the elevating cylinder 40 is operated to elevate the elevating frame 31, and the tip of the adhesive tape C above the adhesive tape sticking roller 33 is rolled by the roll 1.
20 and is pressed and attached to the end of the board Sb immediately below. In this case, the adhesive tape C is adhered so that approximately half of the tape width is adhered to the back surface of the board Sb, and the remaining half width portion is protruded to the side of the peripheral surface of the roll 120.

Next, the running frame 39 is restarted,
The board is run in the width direction of the board Sb. During this traveling, the adhesive tape C is pressed and adhered to both the back surface of the board Sb and the peripheral surface of the roll 120 by the adhesive tape pressing roller 35. In the case of this embodiment, the adhesive tape sticking roller 33 and the adhesive tape pressing roller 35 are formed in a drum shape, and the curved roller surface is formed by applying the adhesive tape C to the peripheral surface of the sheet winding / rewinding roll 120 and the board Sb. It can be brought into close contact with the end face, and peeling and displacement can be effectively prevented.

Immediately before reaching the opposite end in the width direction of the board Sb, the cylinder 33C is operated to lower the adhesive tape sticking roller 33. The adhesive tape C comes into contact with the cutter 38 while being lowered together with the adhesive tape attaching roller 33 and is cut. When the adhesive tape pressing roller 35 arrives at the opposite end in the width direction of the board Sb, the traveling frame 39 is stopped. Next, the elevating cylinder 40 is operated to lower the elevating frame 31, and the adhesive tape attaching device 30 is retracted to the original position.

In this manner, the adhesive tape C is securely attached over the entire length, and the end S _END of the board Sb is fixed to the peripheral surface of the sheet winding / rewinding roll 120 [FIG.
1 (b)]. Next, as shown in FIG.
8 is brought into contact with the peripheral surface of the sheet winding / rewinding roll 120. Then, a shaft 28a is driven by a motor (not shown).
Is rotated to move the belt 28b, thereby rotating the sheet winding / rewinding roll 120 in the winding direction. At the same time, the board Sb is fed out from the paper feed connection section 5 and fed by a required length. As a result, the board Sb is wound around the peripheral surface of the sheet winding / rewinding roll 120. When the rear end of the board cut by the cutter 17 is sent to a predetermined position (a position before being wound on the sheet winding / rewinding roll 120), the operation of the belt wrapper 28 and the feeding of the board Sb are stopped [FIG. c)].

Next, the operation of the cylinder 26 lowers the suction surface of the connection suction box 25 to the sheet feeding path, exhausts the air to suck the rear end of the board Sb,
The suction box 25 for connection is raised by the reverse operation of 6. As a result, the rear end of the board Sb is lifted above the sheet feeding path. On the other hand, in unreel section 4,
Select the required anti-corrosion paper Sa example a roll A ₂ on the basis of the coil information from among the wrapping raw sheet roll A ₁ to A ₆ which are held in Ann reel section 4, the tip of the anticorrosive paper Sa ( The connection end with the board Sb) is supplied to the paper connection section 5. Then, according to the coil width information, if necessary, for example, the edge cut by the width cutting cutters 21 and 22 to the width dimension of (width of the steel plate coil 1 + β) is sent out by the endless belt mechanisms 23 and 24, and the tip of the rust-proof paper Sa is When the section reaches just below the sheet winding / rewinding roll 120, the feeding is stopped. At this time, the end of the previously wound board Sb is lifted above the sheet feeding path by the connection suction box 25, and therefore does not hinder the feeding of the rust-proof paper Sa. The tip of the rust-proof paper Sa is
It can be easily confirmed from the outside whether or not it is located just below 0, and positioning is easy (FIG. 11D).

Next, the suction of the connection suction box 25 held above by sucking the rear end of the board Sb is released, and then the sheet winding / rewinding roll 120 is moved in the winding direction by the belt wrapper. By slightly rotating the sheet Sb and the rust-preventive paper Sa, the rotation of the sheet take-up / rewind roll 120 is stopped by adjusting the overlap length (overlap margin) of the board Sb and the rust-proof paper Sa to a predetermined length. In this case, the positions of the rear end of the board Sb and the front end of the rust-proof paper Sa can be easily confirmed, and the overlap margin can be accurately and easily controlled. (For example, in the case where the tip of the rust-proof paper Sa is inserted and connected between the roll 120 and the board Sb, it is difficult to confirm the position of the tip of the rust-proof paper Sa and it is not easy to accurately control the overlap margin. ).

Subsequently, the adhesive tape adhering device 30 is restarted and operated in the same manner as in the case of the board Sb to connect the rear end of the board Sb and the front end of the rust-proof paper Sa with the adhesive tape C. [FIG. 11E]. Next, belt wrapper 2
8, the sheet winding / rewinding roll 120 is rotated again to start winding the rust-proof paper Sa, and at the same time, the rust-proof paper Sa is fed out from the paper passing connection section 5 and the required length is fed. Then, the rear end (start end of winding around the steel sheet coil 1) S _START is cut by the cutter 17, and the rear end S _START is _fed to a predetermined position and stopped [FIG. 11 (f)].

In this way, the operation of temporarily winding the two kinds of packaging sheets S (rust-proof paper Sa and board Sb) having different functions on the sheet winding / rewinding roll 120 while connecting them in series is completed. Next, referring to FIG. 10 and FIG. 12, the operation of wrapping the rust-proof paper Sa and the board Sb around the outer periphery of the steel coil 1, that is, the action of double packaging of the steel coil 1 using the rust-proof paper Sa and the board Sb. Will be described.

When the coil 1 to be packaged is transported to the packaging position by the coil transport equipment 2, the cylinder 126 provided in the coil lifter 3 is operated based on the coil information,
The inner diameter support rod 3a is raised to the same height as the inner diameter hole of the steel plate coil 1. Next, by operating the cylinder 125, the coil lifter 3 is advanced in the direction of the coil transfer line 2, and the inner diameter support rod 3a is inserted into the inner diameter hole of the steel plate coil 1 and stopped.

Subsequently, the cylinder 126 is operated again to raise the inner diameter support rod 3a, and the steel sheet coil 1 is raised to a predetermined height at the time of winding the wrapping sheet and then stopped. Next, the motor 115 of the sheet take-up / winding device 6 is driven to move the sheet take-up / rewind roll 120 from the sheet temporary take-up position to the rewind position (that is, the angular position at which the winding of the sheet coil 1 is started). Turn.

Subsequently, as shown in FIG. 10, the traveling drive motor 111 is driven to cause the traveling carriage 100 to travel toward the coil conveying line 2 and stop at a predetermined position. next,
With reference to FIG. 12, the wrapping procedure will be described together with the operation of the wrapping sheet holding section 7. First, the turning cylinder 76 of the sheet feeding device 70 (see FIG. 7) is operated to bring the rotating belt 71 into contact with the rust-proof paper Sa wound on the sheet winding / rewinding roll 120. Thereafter, the rotary drive roll 72 is driven by a motor (not shown) to rotate the rotary belt 71. Thus, rewinding of the rust-proof paper Sa wound on the roll 120 is started. Rustproof paper S
When the leading end _{SSTART of a} is extended and hangs down by a predetermined length, the rotating belt 71 is stopped to stop the extension [FIG. 12 (a)].

Subsequently, the auxiliary suction rod device 80 (see FIG. 9)
Actuate the cylinder 84 to advance the kick rod 81,
The tip of the rust-proof paper Sa hanging down at the tip is kicked up toward the holding suction box 61 and sucked and held by the holding suction box 61 [X _{1 in} FIG. 12B].
In this manner, by catching the winding start end of the rust-proof paper Sa, the holding suction box 61 is lowered, and the steel coil 1
, And can be accurately and reliably fixed at a predetermined position with respect to the outer periphery of the steel sheet coil 1 without an adhesive tape.

Next, the sheet winding / winding device 6 (FIG. 1)
In step 0), the sliding frame 117 is lowered by driving the motor 119, and the lifting frame 54 of the sheet pressing device 50 is lowered, so that the holding suction box 61 and the sheet pressing device 50 are both lowered. Holding suction box 61
The winding start end S _START of the rust-proof paper Sa adsorbed on the sheet comes into contact with the peripheral surface of the steel sheet coil 1, while the sheet winding / rewinding roll 120 and the holding roll 121 are slightly separated from the peripheral surface of the steel sheet coil 1. The descent is stopped at the position [X _{2 in} FIG. 12 (b)].

Next, the motor 115 of the sheet winding / winding device 6 is driven to rotate the sheet winding / rewinding roll 120.
Then, the pressing roll 121 is moved in association with the outer circumference of the steel sheet coil 1 [X _{3 in} FIG. 12B]. By this rotation, the rust-preventive paper Sa is transferred to the sheet winding / rewinding roll 120.
And wound around the peripheral surface of the steel sheet coil 1.

In the initial stage of this rotation, the sheet winding / rewinding roll 120 is moved by the sheet pressing device 50 (at this time,
When the snubber roll 56 and the curved arm 57 are retracted above the roll), the cylinder 59 is actuated to turn the curved arm 57 downward, and the rust-proof paper Sa wound around the steel sheet coil by the snubber roll 56. Press and hold against 1.

Eventually, the sheet winding / rewinding roll 120 orbits around the steel sheet coil 1 by almost one turn, and adsorbs the sheet leading end pressing the winding start end S _START of the rust-proof paper Sa against the peripheral surface of the steel sheet coil 1. It approaches the holding device 60. At that time, the suction of the sheet holding suction box 61 is stopped to release the suction, and then the lifting cylinder 64 (see FIG. 8) is operated to raise the sheet holding suction box 61 so that the sheet take-up / rewind roll 120 Evacuation to a range that does not interfere with the lap.

The sheet winding / rewinding roll 120 continues to rotate around the steel sheet coil 1 as it is, passes below the retracted sheet holding suction box 61, and holds the rust-proof paper Sa on the steel sheet coil 1. It temporarily stops at an intermediate position with the roll 56 [Y _{1 in} FIG. 12C]. Next, the lifting / lowering cylinder 64 is operated to operate the sheet holding suction box 6.
1 is lowered, and the rust-proof paper Sa wound around the steel sheet coil 1 is pressed against the peripheral surface of the steel sheet coil. At this time, rust-proof paper Sa
And the end of the board Sb connected thereto is wound as shown in FIG. In this case, the winding length of the rust-proof paper Sa and the overlap of the board Sb are prevented by the sheet winding / rewinding roll 120 in the previous step so that the rust-proof paper Sa is in contact with the entire circumference of the steel sheet coil 1. It is adjusted when the rusted paper Sa and the board Sb are temporarily wound while being connected with the adhesive tape C.

Next, the cylinder 59 is operated to rotate the curved arm 57 and the snubber roll 56 to retract upward, and then the motor 1 of the sheet winding and winding device 6 is again rotated.
The sheet winding / rewinding roll 120 and the pressing roll 121 are driven to rotate around the outer periphery of the steel coil 1 by driving the sheet winding 15 [Y _{2 in} FIG. 12C]. By the second round, the board Sb is wound around the rust-proof paper Sa. The snubber roll 5 in which the sheet take-up / rewind roll 120 is retracted upward at the beginning of the second round.
After passing under 6, the curved arm 57 is turned down by operating the cylinder 59, and the board Sb is pressed and held by the snubber roll 56 against the peripheral surface of the steel plate coil 1.

Before the sheet take-up / rewind roll 120 completes the second round, when the rust-proof paper Sa approaches the sheet tip suction holding device 60 pressing the circumferential surface of the steel sheet coil 1, the sheet holding sheet The exhaust of the suction box 61 is stopped to release the suction, and then the lifting cylinder 64 is operated to move the suction box 61 for holding the sheet up and down. When the sheet winding / rewinding roll 120 passes below the retracted sheet holding suction box 61 and reaches just before the two peripheral ends, the cylinder 124 of the sheet winding / winding device 6 is operated to hold the sheet. The roll 121 is pressed against the coil 1. In this state, the sheet take-up / rewind roll 120 rotates to the first winding start position and then stops.
As a result, the adhesive tape C fixing the end of the board Sb to the sheet winding / rewinding roll 120 is peeled off from the roll surface, pressed down by the holding roll 121, and adhered to the other end of the board Sb. .

In this way, the rust-proof paper S
a and the board Sb are double-wound and held as shown in FIG. When the wrapping of the rust-proof paper Sa and the board Sb is completed, each part of the multiplex wrapping device returns to the original standby position, the sheet winding / winding device 6 retreats to the winding position, and wraps the next steel sheet coil 1. Get ready. Further, the coil lifter 3 descends, places the coiled steel sheet 1 on the chain conveyor skid, and retreats.

According to this embodiment, in the multiple winding step of the wrapping sheet S around the steel sheet coil 1, the wrapping sheet S is always held down by at least one of the sheet holding suction box 61 and the snubber roll 56. Therefore, the wound packaging sheet S is not shifted or loosened. In particular, the packaging sheet S can be packaged with the connection between the preceding sheet and the following sheet completely fixed to the steel sheet coil 1.

[0073] In this embodiment, it is possible to a case has been described of a double-winding Bosabishi Sa and board Sb, carried in exactly the same manner even if different package sheet more than triple winding of functions.
