Forming a tape feed mechanism such that a tape feed angle β formed between the horizontal surface and the tape between the rollers 11 and 12 is α = β, and a cutter is attached to the attaching roller, and the cutter and the attaching roller are synchronously controlled. An inner peripheral taping device for a packaging material, characterized in that: Further, the present invention is an inner peripheral taping device for a packaging material in which a paper lifting prevention roller is provided on the coil end surface side of the attaching roller and a main body protection roll is provided at the same level on the coil center side.

The present invention will be described below with reference to the drawings. In the present invention, in the inner peripheral taping device of the packaging material folded at the end face of the metal plate coil of the down-end type and folded on the inner peripheral surface, the metal plate coil advances and retreats with respect to the metal plate coil placed on the rotating mechanism. A flexible support is provided, and the tape coil 3 is disposed on the support. The taping device of the present invention includes a sticking roller, an auxiliary roller, and a cutter, and has a driving cylinder for each. A driving cylinder is provided in the taping device, and the taping device can be moved up and down freely.

[0008] A roller 8 is attached to the rotating side of the metal plate coil.
And the auxiliary roller 9 are provided in parallel with the tape coil 3. The attaching roller 8 and the auxiliary roller 9 are provided with lifting cylinders 21 and 22, respectively. A plurality of tape guide rollers 11, 12, 13 are provided below the tape coil 3 to form a tape feed mechanism having a tape feed angle α. The tape guide roller 11 and the guide roller 12 form a tape feed angle α, and the guide roller 13 functions as a feed mechanism by pinching the sticking roller 8 and the tape 4.

Further, the guide rollers 12 and 13 can be moved up and down together with the attaching roller 8 to form a tape feed angle β when the tape is adhered. Cutter 17 on sticking roller 8
Is provided, a cutter cylinder 18 is provided, incorporated in the same system as the attaching cylinder 21, and a control system for operating the cutter and the attaching roller in synchronization is provided.

FIG. 1, FIG. 2, and FIG. 3 show the main parts of the present invention. (1) The entire device has a coil minimum diameter in the circumferential direction in a standby state and a range that does not interfere with the grip height h.
The width (depth) is designed to be equal to or less than 1/2 of the minimum coil width (this is due to the provision of taping devices on both sides of the coil). (2) The device elevating cylinder 26 is attached to the support 25. When the cylinder 26 is operated, the tape coil 3, the tape guide rollers 11 , 12, and 13 , the attaching roller 8, the attaching roller elevating cylinder 21, the auxiliary roller 9, and the auxiliary roller 9. The roller lifting cylinder 22 , the cutter 17, the cutter cylinder 18, the main body protection roll 14, and the paper lifting prevention roller 15 move up and down. (3) Only the cutter cylinder 18 in the apparatus is in the extended state, and all the other cylinders are in the pulled state, and the apparatus is in the standby state. At this time, it is horizontal between the guide rollers 11 and 12.
Tape feed angle between the surface and the tape, ie at the time of the waiting you
Α is the tape feed angle to be applied. There is an uncut remaining tape tip below the attaching roller 8 , and the attaching roller 8 and the cutter 17 operate synchronously, so that the uncut remaining tape tip length is stable.

(4) After entering the inside diameter of the coil, the attaching roller 8 is taken out (pulling of the cutter). This is the preparation state. At this time, the tape feed angle between the horizontal surface and the tape between the guide rollers 11 and 12 , ie, the
The loop feed angle is β. Since the angle between the horizontal surface between the guide rollers 11 and 12 and the tape is α = β, the length of the leading end of the tape corresponding to the uncut portion is maintained as long as the sticking roller is inserted (guide roller arrangement effect). (5) The leading end of the wrapping paper attached to the coil rotates together with the coil and passes below the attaching roller, and at the same time the attaching roller comes into contact with the leading end of the paper, the apparatus elevating cylinder is ejected. When the sticking roller touches the leading edge of the paper,
The tip of the remaining tape is stuck to the paper. (6) The tip of the tape goes down the auxiliary roller after passing through the auxiliary roll. (If the tape passes after the lowering of the auxiliary roll, if the tip of the tape rises, the tape is stuck to the auxiliary roller and the taping operation cannot be continued. ). Thus, the auxiliary roll has its own lifting effect.

(7) Although the rotation of the coil is continued, since the leading end of the tape is stuck to the paper, the tape is also stuck around the circumference, during which time the tape is supplied from the tape coil. When the coil grip passes, the entire device smoothly passes over the grip by the main body protection roll (main body protection roll effect). (8) When the application of the tape for the circumference of the coil inner diameter is completed, the application roller is raised. The cutter cylinder comes out,
Cut the trailing edge of the tape between the application roller and the auxiliary roller.
At this time, the cutter is disposed between the application roller and the auxiliary roller. The tape also rises when the sticking roller rises,
The attached paper floats with the tape, and when the tape is cut in this state, the cutter blade cuts into the raised paper,
Cutting flaws appear on the wrapping paper. In the present invention, this is prevented by a paper lifting prevention roller and a main body protection roll provided on both sides of the sticking roller (the main body protection roll plays a dual role of getting over the grip). (9) After the rear end of the tape is cut, the auxiliary roller is pressed until the rear end of the tape passes. Therefore, the rear end of the tape and the auxiliary roll have an independent lifting / lowering effect. (10) After the trailing edge of the tape has passed, the auxiliary roller rises, the device elevating cylinder rises, and the apparatus enters a standby state, ending the work cycle.

In the present invention, as shown in FIG. 4, a roll 15 is supported on the coil end face side of the sticking roller 8, and a roll 14 is supported on the coil center side. The rolls 14 and 15 are located on both sides of the sticking roller 8 at the same level. As shown in FIG. 5, a cylinder is provided for each of the attaching roller, the tape cutter, and the auxiliary roller, and the entire taping device has an elevating cylinder. The cylinder of the tape cutter and the cylinder of the sticking roller operate in the same manner. The present invention does not use a drive motor, does not require a suction device, and uses a plate cylinder, a low friction cylinder, a CDG type cylinder, or the like, but is not limited thereto.

In the present invention, by feeding the tape tip to the inner surface of the coil with a sticking roller, the tape is simultaneously supplied and adhered by the rotation of the coil. In addition, since the cutter and the sticking roller have the same operation source and operate synchronously, the cutter descends when the sticking roller rises when the sticking is completed. The length of the coil is secured, and the tip of the next coil is securely attached.

Since the tape guide roller 11 operates in the same manner as the coil tape and the tape guide rollers 12 and 13 operate in the same manner as the sticking roller, and the angle between the guide rollers 11 and 12 moving up and down is set to α = β. There is an advantage that there is no difference in the tape supply length at the time of elevating and there is no influence on the tape sticking length. Further, since the auxiliary roller 9 which can be moved up and down independently is arranged, the tape position at the time of cutting is always constant with respect to the cutter, so that the tape can be cut reliably. Also, it can be stuck securely to the end of the sticking tape.

In the present invention, the tape rises when the sticking roller rises, but the wrapping paper also rises along with the tape, and there is a possibility that the packaging paper may have a cutter flaw when cutting. A paper lifting prevention roller 15 for preventing this was mounted. Further, a protection roll 14 is mounted for the purpose of protecting the entire device by the grip existing in the inner diameter portion of the coil, and the entire device can be smoothly retracted by the protection roll when passing through the grip.

That is, the tape tip is brought into contact with the inner surface of the coil by a sticking roller, and the supply and sticking of the tape are performed simultaneously by the rotation of the coil. Attach the tape guide rollers between the sticking rollers during the standby and when attaching.
Are arranged so that α = β
A tape feeding mechanism is provided, an auxiliary roller which can be raised and lowered independently is provided, and a paper lifting prevention roller and a protection roller at the time of passing the grip are provided. Therefore, the concerns of the conventional example, in which the leading end of the tape cannot be securely adhered, the trailing end of the tape cannot be reliably cut, the trailing end of the tape cannot be adhered (raise), and a wrapping paper cutter flaw is generated when the tape is cut, are completely eliminated.

[0018]

According to the present invention, a drive motor, a tape suction device, and the like are not required, and the tape can be stuck and cut without fail.
