Definitions

• the automatic web winding device of Honki Ming is a process that automatically winds a web that is to be lined up automatically, and efficiently and reliably winds the work from the supply ⁇ -roll to the core.
• a cutting mechanism having a cutting blade is brought close to the web, the web is cut in a tension state between the supply roll and the full winding core, and after cutting, the cut portion is pressed into contact with the fiber.
• the new winding core is brought close to the web, while the tape sticking roll is made close to both sides.))
• the web is sandwiched to supply the cutting edge of the web.
• the adhesive tape on the tape affixing roll glue the adhesive tape on the tape affixing roll to the cut end of the web, and adhere to the new core with the remaining part of the adhesive tape as the web moves. And fix the web to the new core.
• the new core is wound on the web.
• the adhesive tape is necessary for bonding the web to the new core separately from the operation of the cutting mechanism, so that the cut portion of the web is fixed to the new core. Therefore, it is better to be supplied at the same time as cutting. Therefore, it is convenient to be integrated with the cutting mechanism.
• the supply of the adhesive tape is performed by previously holding the tape on a tape attaching roll. That is, the adhesive tape is placed at a position on the ⁇ -rule that presses one part of the edge of the tape while rotating the tape sticking hole. This allows for efficient work.
• FIG. 1 is a configuration diagram showing a state during winding in an example of “EB automatic winding” according to the present invention
• FIG. 2 is a state when the web is in a waiting state due to web cutting
• FIG. 3 is a configuration diagram
• FIG. 3 is a configuration diagram when the web is cut.
• Fig. 4 is an explanatory diagram showing the relationship between the web length L from the nip point to the cut ⁇ ; ⁇ and the holding position of the adhesive tape on the tape.
• Figure: FIG. 4 is an explanatory view showing the three states until the cut portion of the blade is attached to the new core.
• FIG. 4 is a detailed explanatory diagram of a positional relationship in a cutting state (FIG. 3).
• S is a point on the tape holding surface 1 9 a, the single-sided adhesive tape 2 1 'signal W ⁇ i: a point we leave for internally dividing ⁇ 2.
• N is a point at which the tape attaching port 19 is joined to the new core 7 via the web 8, that is, a nib point.
• the tape from the double point N to the internal dividing point S is attached to the tape.
• the straight line up to the upper blade 18 is selected as equal to L (ie, the length from the double point N to the end of the web) L.
• the inside of the tape attaching roll 19 is sucked to a negative pressure, and the single-sided adhesive tape 21 fed and fed by the tape feeder 22 a little longer than the web width is supplied.
• the adhesive is held with the adhesive surface facing outward. 0 This completes the preparation operation.
• the turning arm 3 of the turret winding machine 1 is rotated to the switching position as shown in FIG. 2, and the swing arm 15 is rotated. Descend to the position where it touches the web 8 and wait for the core change.
• the nipple 1 2 force is closed; the wrap roll 12 is closed.)
• the running of the downstream web 8 stops. I do.
• the swing arm 15 descends further, the taper roller 19 contacts the new winding core 7, and the upper cutting blade 18 enters the groove 40]) and the lower cutting blade 5 If so. This is done outside of Eve 8.
• the swing time 15 from the state of FIG.
• the inside of 4 a is open to the atmosphere, and the web 8 on the delivery side is cut off from the suction board 4 and the electromagnetic brake 2 ⁇
• FIG. 5 (a) to indicate the ⁇ rather, Teishakumodo and b Nore 1 9 force;
• (L I) can and moves by 2
• U E Bed 8 is L- ⁇ ⁇ was Technology of above up is Once the single-sided adhesive tape 2 1 c E against the blanking 8 ⁇ teeth. further moves to Teishakumodo rather ⁇ shown in FIG. 5 (b) ii Nore 1 9 L / 2 to move, U E cut end 8 a of the probe 8 a two-Tsu reached the blanking point N, Chi sales of tape width W of the single-sided adhesive tape 2 1 ⁇ ! Only affixed to web 8.
• the cut end 8 of the web 8 is stopped with a tape or the like to form a roll of the full core 6. Even during this work, the web 8 is wound around the core 7, and the preparation operation for the next core exchange is also in progress. Then, when the required amount of the web S is wound on the winding core 7, the immediate operation such as attaching the web 8 to the cut-off winding core of the web 8 is repeated.
• the web 8 ⁇ rear end is held by the suction board 4 before moving to the tape fixing operation of the web 8 rear end of the full core 6 side. For this reason, the rear end of the web 8 does not drop and waste is thrown away, and a film failure such as a damaged sticker or a chip is also generated.
• the cut end 8a of the web 8 approaches the new winding core 7 by some method, only the cut portion (the cut end and its vicinity) is doubled, and the adhesive tape is attached thereto. It may be configured so that the tape 21 is attached.
• a straight blade is used as the lower cutting blade 5
• a movable circular blade is used as the cutting new upper blade 18. Both blades 5 and 18 may be inserted, or both blades 5 and 18 may be co-linear.
• the web 8 on the feeding side after cutting is pulled back in the direction opposite to the feeding direction, and at least the web 8 is cut at the time of pulling back.
• Nib with a tape sticker and a new core and the cut end is attached to the new core with an adhesive tape.
• the core switching operation can be unmanned.
• the structure of the winder is simple.> Not only the cost of the whole machine is reduced, but also the reliability of the package is improved.
