BRIEF DESCRIPTION OF THE DRAWINGS The novel features believed to be characteristic of the invention are set forth with particularity in the appended claims. However,
The invention itself, together with further objects and advantages of the invention, can be best understood by the following description taken in conjunction with the accompanying drawings, in conjunction with further objects and advantages of the invention. Here, FIG. 1 is a perspective view schematically showing the apparatus of the present invention, FIG. 2 is an elevational view schematically showing the control mechanism of the apparatus of the present invention, and FIG. 3 is FIG. 1 or FIG. 3 is a sectional view taken along line 3-3, and FIG. 4 is a sectional view taken along line 4-4 in FIG.

BEST MODE FOR CARRYING OUT THE INVENTION The overall features of the present invention are best understood by referring to FIG. This FIG. 1 shows a device of the type commonly used in paper mills, which stores the manufactured paper elsewhere and
It is for winding on a roller for use. A continuous web of paper 20 is sent to a spool at a relatively high speed and wrapped around the spool.
The web of paper 20 is advanced towards a tension roller 21, which is attached to the rotary support of a support 22, which guides the web of paper 20 to a drive roller 23, indicated by the arrow 25. And is wound around the spool 24. The drive roller 23 rotates in the direction of arrow 26 and is pressed against the spool 24 by the paper roller to rotate this spool in the direction shown. The required capacity of the spool 24 is the paper web 20.
When filled with, the paper web 20 is transversely cut, and the edge of the cut portion is transferred to the empty spool 27,
It is necessary to start the operation of winding the web around the spool in the direction of the arrow 28, and finally form the web into the shape of another roller such as the spool 24 in a state where the winding of the paper is completed. Is. The empty spool 27 is placed vertically above the position shown in FIG.
Is prepared for acceptance and maintained until the wrapping of this paper is started. The empty spool 27 may be individually rotated as is known in the art or may not be so rotated and the empty spool 27 is lowered until it contacts the drive roller 23. The drive roller is rotated as shown in FIG.
After that, the paper web 20 is cut and the web 20
Since the leading edge of the spool is wrapped around the empty spool, the empty spool continues to wind the web 20, and the continued spooling of the web of paper with the empty spool causes the spool to be wound onto another empty spool. It is carried out until it is ready to be replaced. According to the present invention, similar to the applicant's invention cited above, this web 20 is cut, and the cutting of this web 20 causes the front end 34 of the cutting tape 33 to move to the nip 29 of the empty spool 27. And through the drive roller 23 at the far end of the roller, by cutting this web 20,
The cutting tape itself is spirally wound around the empty spool 27, while the web 20 is transversely cut in front of the empty spool 27 and the web 20 is automatically conveyed to the empty spool 27. At times, the web 20 can continue to be wound around this empty spool. The cutting tape 33 is guided from an end 32 on the front side to an end 31 on the far side in a guide path 30 passing below the moving web 20 of paper. In the present invention, the front end 34 of the cutting tape 33 is guided from the guide path 30 to the vicinity of the outlet at the end 31 on the far side, and stops at this position. This stop is done to wait an appropriate amount of time to advance to enter the nip 29. The final movement of the front end 34 into the nip 29 can be made automatic, which involves cutting the web of paper and winding it onto a spool. The movement of some part of the device to be performed can be governed using movements, such as movement of the main arm of the spool to activate a limit switch. Further, the final movement of inserting the front end portion 34 into the nip 29 can be carried out by the switch activation of the operator. An important feature of the present invention is that all control equipment, operating equipment, and checkpoints are at the front end 32 of the spool 21, 23, 24, 27 so that the operator can move the paper. While traveling underneath or straddling over the web 20 of paper, it travels several feet to guide the front end 34 of the paper web 20 to be cut into the nip 29 and empty the web. This means that it is not compulsory to start the work of winding the spool 27.

A key feature of the present invention is that the control equipment, the sensing device, and the operating device are located at the front end 32 of the spool and the web 20 of paper. The mutual relationship between these devices and apparatuses is shown in FIG. 1 and FIG. The cutting tape 33 is a plurality of parallel fibers of paper that can be twisted and redissolved, which is similar to the one described in the applicant's patent already described. 33 is stored in a large paper feed spool 35, introduced from the paper feed spool 35 into an inlet 40 of the guide path 30, and introduced into a vertically inverted T slot as shown in FIG. Where the T-slot crossbar 73 is the conduit for the cutting tape 33,
The leg 74 of the slot is an opening extending in the length direction of the guide path 30. Since the shallow recess 75 along the bottom of the crossbar 73 is incorporated in the guide path, the adhesive is applied to the portion of the cutting tape 33 corresponding to this recess at this recess. Moreover, the cutting tape 33 does not come into contact with the guide path 30. As can be seen, the cutting tape 33 is supported on the side edges of the crossbar 73 by the side edges of the tape as it moves. Since the cutting tape 33 has sufficient toughness so as to bridge the recess 75 so as to bridge it, no problem of frictional resistance occurs when the cutting tape 33 passes through the guide path 30.

Cutting tape 33 sent from the supply spool 35
Passes between the rollers 36 and 37 and is advanced by the roller 36, and the cutting tape 33 captured by the roller 36 is pressed by the pressing roller 37.
6 is pressed. This pressure is applied by a lever 38, on which the pneumatically operated cylinder device 3
9, the cylinder device 39 presses the pressing roller 37 against the roller 36. The rollers 36 are rotated by devices not shown here, such as shafts driven by motorized pulleys and belts. The cutting tape 33 enters the guide passage 30 from the entrance 40 of the guide passage 30 and further into the T slot which has already been described.
Is detected by the photocell detector 40 '. If no cutting tape 33 is present in the guideway 30, the operator replaces the feed roller and / or starts the cutting tape between the rollers 36, 37. In any case, the cutting tape 33 is advanced to the end of the guide path 30 by intersecting the distal end 31 so that the front end 34 is about 76.2 mm (about 3 inches) of the nip 29. ) In front. The detector 77 detects that the front end portion 34 has passed, and the braking cylinder 6
0 and send a signal to the loop gate cylinder 57,
The functions of these cylinders are demonstrated. Instead of such a structure, the detector 77 can be omitted, and the pressing roller 37 is controlled so as to rotate at a selected rotational speed and passes the detector 80. Control is performed so as to perform partial rotation measured using the upper equidistant pickup point 79, and control is performed using this pressing roller 37 so that the cutting side end portion 34 is accurately advanced to a position before the nip 29. Even if you don't use it. The braking pads 59 are located opposite each other from both sides of the cutting tape 33 and are pressed together by the air-operated braking cylinder 60 to stop the movement of the cutting tape 33, thereby cutting tape. It completely prevents 33 from moving towards the far end 31. The air-actuated cylinder 57 is activated to draw a portion 56 of the T-slot into the guideway 30, leaving an unobstructed opening 58 in the temporary storage space. .

This storage space is formed by the guide wall 69 and allows the large loop portion 70 of the tape 33 to hang down, as shown in FIG. Drive roller 36
Continues to insert cutting tape 33 into inlet 40 to form loop portion 70. The pressing roller 37 is
It is calibrated to rotate at a predetermined number of revolutions and the cutting tape 33 is advanced a selected length,
After that, it stops automatically. When the drive roller 36 is stopped, the guillotine type cutter 41 is activated by the air-operated cylinder 42 to cut and cut the cutting tape 33, and the cutting tape 33 is cut at a proper time. To prepare a cutting tape 33 for use in cutting the web 20 of paper by cutting a selected length of the cutting tape 33 from the cutter 41 to the front end 34 of the cutting tape 33. The cutting tape 33 may be cut off by the operator, or may be automatically set by using a switching device. The changer is activated by the movement of the empty spool 27,
It is done so that it is in a position to receive the paper web 20. When the operator is ready, the cylinder 64 for moving the lever 63 is activated and the pressing roller 62
Is pressed against the cutting tape 33, and the pressing roller 62 presses the cutting tape 33 to rotate the roller 61 that advances the paper by a selected amount. The preferred process is a combination of a rack 81 and a pinion 83, in which case the rack 81 makes a selected linear movement through the support bearing 82 to rotate the pinion 83, and , Roller 61
Is rotated in the direction of arrow 78 to advance the front end 34 until the front end 34 is captured in the nip 29. Immediately after the rotation of the roller 61, the braking pads 59 together press against each other, forming a resistance to the movement of the cutting tape 33 in the guideway 30. The cutting tape 33 is wound around the empty spool 27 in a spiral shape, and is pulled and tensioned. This is because it receives the resistance of the brake 59. As a result, the cutting tape 33 cuts the web 20 of paper, guides the end of the cutting side to the empty spool 27, and the empty spool 2
Let it roll up to 7.

When the web of paper 20 is safely and securely attached to and wound on the empty spool 27, the operator initiates a new cycle of operation. This new cycle of operation is based on another long tape 3
In preparation for advancing 0 into nip 29 to cut web 20 and start a new empty spool 27. Manipulation of the front end 34 begins when the front end passes through the adhesive applicator roller 46, where one long double-sided pressure sensitive adhesive tape, eg, 7 lengths.
A double-sided pressure-sensitive adhesive tape of 6.2 to 101.6 mm (3 to 4 inches) is supplied from the supply roller 47 to the supply roller 48, and this tape 33 is used for cutting.
And the cutting tape 33 by the pressing roller 43.
And further downwards by a lever 44, which is operated by a pneumatically actuated cylinder device 45. The long double-sided adhesive tape 48 is adhered to the cutting tape 33, while the adhesive-surface protective material 49 is peeled off from the double-sided adhesive tape and wound on the winding roller 50. When the front end 34 is advanced forward, the advance of this end is detected by the roller 51, which sends a signal from the detector housing 52 to the pneumatic cylinder device 45, which signals However, the pressure roller 43 is slightly raised from the cutting tape 33, and the adhesive applying roller 46 is moved to the cutting tape 33.
Is not pressed harder, so that only one long adhesive tape is attached to the cutting tape 30.
After that, the cutting side end 34 of the tape passes over the detection roller 53, and the detection roller 53 has a metal surface or another surface, and these surfaces cut the pressure sensitive tape. Adhesive application roller 46 of tape 33
Adhere to the lower side of which is applied to. When the long double-sided adhesive tape passes, the detection roller 53 rotates, which causes the arm 54 to swing in a circle, which is a circle passing near the magnetically actuated switch 55. This actuation sends a signal to the pneumatically actuated switch 66 which keeps the guideway track switch 65 open relative to the cutting tape 33 so that the cutting tape 33 is , So that it can move in the direction of the end 31 on the far side by passing through the straight through portion 72. If for some reason there is no long adhesive tape at the cutting end 34 of the tape, the sensing roller will not rotate and no signal will be sent to the pneumatically actuated switch 66, which will cause The track changer 65 is the cutting tape 33.
About 254 mm (about 1
0 inch) and wait for operator selection in this state.
This choice is a treatment choice whether the operator manually applies the adhesive to the area where the adhesive tape should be attached or sends the cutting tape 33 to the waste collection area. If no adhesive is applied to the cut end 34 of the tape, the cut end 34 of the tape is
Is not caught on the empty spool 27 and therefore the paper web 20 is not cut. If everything is proceeding smoothly, the adhesive tape portion mounted on the cutting side end 34 of the tape guides the cutting tape 33 to the guideway 3
0 to the end 31 on the far side, the braking pad 59 stops the movement of the cutting tape 33, the track portion 56 is removed, the loop portion 70 is formed, and the cutter 41 is used for cutting. Make tape 33 into a circle.

It should be clarified that many of the components of the device shown in FIG. 2 can be replaced by components other than those already described. Air operated cylinder devices 39, 42, 45, 57, 60,
64, 66 can be hydraulic cylinders, solenoids, or other devices that perform linear motion. The roller adhesive applicators 43, 46, 47, 50 are adhesive spraying devices, or U.S. Pat. No. 4,783, already described by the applicant.
It can be replaced with an adhesive application device of the type which applies an adhesive using a roller as described in No. 018. Detection devices 51, 52, 53, 54, 5
5 may be replaced by a light beam blocking device, an X-ray blocking device, or a device similar to these devices and known in the prior art. Lever 3
8, 43, 63 can be spring-biased so that they automatically occupy one position, or use a corresponding pneumatically actuated cylinder to move only in one direction instead of two. It is also possible to do so. Similarly, the guideway track changer 65 is spring biased so that it automatically occupies one position or moves to another position only when given a signal. It is also possible.

Although the present invention has been described above using specific forms, it is possible to add many improvements and changes to these forms using conventional techniques without departing from the idea of the present invention. That is clear. Therefore, the appended claims are intended to cover all such modifications and changes as fall within the spirit and scope of the present invention.
