- MACHINE FOR DISPENSING TAPE 3 Sheets-Sheet 3 1762? for [2? AZfreaz P United States Patent 2,695,058 MACHINE FOR DISPENSING TAPE Alfred P. Krueger, Stratford, Conn, assignor to Derby Sealers, Incorporated, Derby, Conn, a corporation of onnecticut Appiication August 1, 1952, Serial No. 302,146 23 Claims. (Cl. 16439) This application relates to tape-dispensing machines and more particularly to a machine for dispensing pressure-sensitive tape. Such tape is tacky or clingable upon one surface so that it will adhere to the surface of an article upon which it is pressed with a certain amount of pressure. Gn account of its tacky nature the serving or dispensing of tape of this kind has been attended with certain problems.

Prior machines of this type have been generally of two kinds. In one kind of such machines the tape is drawn from the supply roll manually by being engaged with the fingers and pulled from the roll. In the other type of machines for dispensing tape the tape is drawn from the supply roll by its adherence to a feeding device, the feeding device being moved for this purpose. In the present instance the feeding device is a feeding roll, and this roll is rotated to draw the tape from the machine. As indicated, this is a device of the second type above referred. to in that it is adapted to draw the tape from the supply roll by movement of a lever or the like which is operated manually, the movement of the lever serving to rotate the feed roll to which the tape adheres.

In a dispensing mechanism of the type illustrated in the present application it is desirable that. the movement of the lever by the operator not. only serve to dispense a proper length of tape but also serve to sever the dispensed portion of the tape and support this severed portion with a portion or free end in extended position so that it may be readily grasped by. the operator in a convenient manner to be applied to a package or other article.

In the present invention a device is provided which will dispense a given length of pressure-sensitive tape by drawing the tape from the supply roll, severing it, and delivering the severed portion to such a position that it may be readily grasped by the operator in a manner in: which it may be conveniently applied to a package. Moreover, the length of tape which has been severed will be supported by the device only at its severed end, the remainder of the severed portion projecting from the machine whereby it may be freely grasped.

In the present device a feed roll is provided to draw the tape from the supply roll, and the tape is stripped from the feed roll before being severed. This is a departure from the operation performed by certain prior devices. in which" the tape is held by the feeding device during the severing operation.

Also in the present mechanism the feed roll is rotated during. the. feeding operation, but at the end of this operation this roll is restrained against rotation and moved bodily with respect to the severing member or knife so as to carry the tape over the edge of the knife in order to sever it. At the same time the tape is gripped upon both sides adjacent the knife so that it will be cleanly severed- It may also be noted that the knife or severing blade is guarded so that there is no danger of itsbeing contacted by the fingers of the operator. This guard'member for the knife serves as one of the gripping members to grip' the tape at one surface thereof and also serves as the tape-end-supporting member which supports the severed portion of the tape with its free end extending in position to be grasped by the operator.

One objectof the invention is to provide a novel apparatus for dispensing pressure-sensitive tape.

A further object of the invention is to provide a device for dispensing pressure-sensitive tape such that a predetermined length of tape will be drawn from a supply roll, severed, and delivered in a position in which it tit) projects from the machine, and hence may be readily grasped by the operator.

A still further object of the invention is to provide a device for dispensing pressure-sensitive tape, which device will draw a predetermined length of tape from a supply roll by forward movement of a lever or similar manually operated element, and by a continued movement of this element cut or sever the dispensed length of tape while discontinuing the rotation of the feed roll during the severing operation.

A still further object of the invention is the provision of a tape-feeding mechanism having a feed roll to draw a length of tape from a supply roll in which the feed roller is rotated during the feeding operation, and thereafter the rotation of the feeding roller is discontinued and this roller with the tape clinging thereto is moved bodily toward a severing member in order to present the tape to the severing member at a point adjacent the roller.

Still another object of the invention is to provide a tape-dispensing machine of the character described above in which provision is made for stripping the tape from the feeding roller so that it will project forwardly from the machine, and after the severing operation a freely extending end will be presented where it may be readily grasped by the operator.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

To illustrate a preferred embodiment of my invention I have shown in the drawings a mechanism for dispensing pressure-sensitive tape comprising a frame having an upstanding portion 10 and a lower horizontally disposed flange or base portion 11. Mounted upon the upstanding portion of the frame is a shaft or spindle 12 upon which is rotatably mounted a spool 13 for holding a supply roll of tape 14, the spool being provided with a hub collar or sleeve 15 rotatable upon a second collar 16, which in turn is rotatably mounted on the spindle l2.

Secured to the collar 16 so that it is also rotatably mounted on the spindle 12 is a gear 17 having peripheral gear teeth 18. The collar 16 is in turn rotatably mounted upon a collar 20 also rotatably carried by the spindle l2.

Pivotailv mounted on. the spindle l2 adiacent the frame member lb so as to be capable of oscillating forward and reverse movement on the spindle is an actuating member or lever 21. This member 21 is provided with an arm 22 upon which is pivoted a pawl 23 held in engagement with the teeth of the gear 17 by the spring 24. As will be noted this provides a one-way connection between the actuating member and the gear so that when the former is moved in. a counter-clockwise direction, as shown in Fig. 1, it will rotate the gear in that direction, but when the actuating member is moved in a clockwise direction the pawl 23 is free to move over the teeth of the gear even though the latter is held against rotation. A coil spring 25 is secured at one end to a pin 26 mounted on the frame, and the other end of the spring is secured to the actuating member at 27 so as to urge this member in a clockwise direction. A stop pin 22; may be mounted in any one of a plurality of openings 29 in the frame to limit the movement of the member 21 under the tension of the spring and thus adjust the normal starting position of the actuating member.

Secured to the collar 29 so that it is rotatable upon the spindle 12 is a carrier member 30 for the feed and stripper mechanism. This carrier member also oscillates on the spindle 12 and is urged in a clockwise direction by a spring 32 secured at one end to a pin 33 in the frame and secured at the other end, as at 34, to the carrier. This spring normally holds a lug 35 on the carrier against a pin 36 (Fig. 2) on the frame so that the carrier normally stands in the position shown in Fig. 1 as do all the parts of the mechanism. Pivoted at the rear end of the carrier member is a pawl 37 normally urged by the spring 38 into engagement with the teeth of the gear 17, the arrangement being such that the gear may rotate in a counter-clockwise direction even though the carrier member 30 is held against movement, while the gear will be positively moved when the carrier is moved in a counterclockwise direction.

The forward portion of the carrier is shown in Fig. 7 of the drawings where, as is illustrated, this member is provided with openings 40 and 41 within which may be secured the inner ends of the shafts 42 and 43 (Fig. 6) of the feed roll 44 and stripping roll 45 respectively so that these rolls are rotatably mounted upon the forward end of the carrier. As shown, these rolls are provided with disk- like elements 46 and 47 respectively, the disks of one member overlapping with those of the other so that the disks 47 of the stripper roll will rotate between and strip the tape from the feeding disks 46 of the feed roll 44.

Secured to the shaft 42 of the feed roll is a pinion 48, while a pinion 49 is similarly secured to the shaft 43 of the stripping roll. The teeth of these pinions are both in mesh with a pinion 50 mounted on a short shaft secured in the opening 51 of the carrier 30 so that when the pinion 50 is rotated the feed roll 44 and stripping roll 45 will likewise be rotated, the adjacent surfaces of the disks 46 and 47 moving in opposite directions.

As shown in Figs. 1, 3 and 4, the teeth of the pinion 50 are in mesh With those of the gear 17 so that rotation of this gear will effect rotation of the pinion and of the feeding and stripping rolls. It may also be noted that if any one of these pinions is held against rotation, the remaining ones of these elements will also be prevented from rotation. However, when the carrier is released the pinions 48, 49 and 50 may, without rotation, move about the axis of the gear 17 as a unit when the latter rotates.

The carrier 30 is provided at its forward end with a laterally extending portion 53, and secured to this part of the carrier is a plate 54 having a rearwardly extending ear 55, and a tape-contacting roll 56 is rotatably mounted at one end in this ear and at the other end in the carrier 30. As shown more especially in Figs. 1 and 3, the free end of the tape 57 is drawn from the supply roll 14 by its adherence to the disks 46 of the feed roll 44 and is stripped therefrom by the stripping roller 45, the tape passing between the disks of the last-named roller and the guide roller 56, he latter contacting the nontacky surface of the tape. When a portion of the tape is dispensed it extends outwardly from the stripping roll, as shown in Fig. 3, prior to the severing operation.

A detent 58 is pivoted at 59 to the frame and urged in a counter-clockwise direction about its pivot by the spring 60 secured at one end to the lower end of the detent and at the other end to the pin 26 on the frame. In the position shown in Fig. l a shoulder 61 on this detent lies below the lug 35 of the carrier 30 and normally holds this carrier against movement in a counter-clockwise direction. It will be noted, however, that the arm 21 is provided with downwardly projecting fingers 62 and 63. The finger 63 is provided with a beveled or cam-shaped corner 64 to engage the upper beveled end 65 of the detent 58 and cam this member in a clockwise direction about its pivot to release the lug 35 from the shoulder 61. At approximately the same time a laterally turned lug 66 on the finger 62 engages the upper side of the lug 35 and causes the carrier 30 to move in a counter-clockwise direction with the actuating lever 21 and effect bodily movement of the feed roll and stripping roll in a downward direction as shown in Figs. 1 and 3. As shown in Fig. 3 the upper end of the detent 58 has been cammed toward the right and the lug 66 is about to engage the lug 35. Thereafter the carrier will be moved with the lever 21 in a counter-clockwise direction.

Rotatably mounted on the collar 16 is an arm 63 shown in perspective in Fig. 9. This arm is provided with a slot 69 which receives a pin 70 secured to the frame so that the arm is limited in its movement about the spindle 12 and is normally urged in an upward or clockwise direction, as shown in Fig. l, by a spring 71 secured at one end to the arm and secured at the other end to a pin 72 upon the carrier 39.

At its free end the arm 68 is provided with a plurality of stripper fingers 73 disposed in a plane extending laterally to the plane of the arm 68 so that these stripper fingers extend between the disks 47 of the stripper roll 45 and serve to insure that the dispensed end of the tape does not follow this roll and cling thereto but is stripped therefrom at a predetermined time in the operation of the device for proper severing.

Secured to the upstanding portion 10 of the frame is a bracket 75 to which is secured in upstanding position a severing member or knife 76. Also secured to the bracket 75 is a channel-shaped guard member 77 in the channels of which is slidably mounted a guard member 78, the guard member being urged to an upward position, as shown in Fig. 2, by a spring 79 secured at its upper end to the member 77 and at its lower end to the guard member 78. As shown in Figs. 1 and 2, for example, the upper edge of the guard member normally stands above the upper edge of the severing member 76 so that the knife will be guarded and at the same time the severed end of the tape will cling to the upper end of the guard after its is severed so that it will be presented for engagement by the fingers of the operator. For this purpose a narrow plate 80 may be secured to the upper end of the guard in order to provide it with a broader upper end surface to which the tape may cling.

The operating lever 21 is provided at its free end with a laterally extending portion 21 the lower end of which is turned outwardly at 21 so that it may be conveniently engaged by the fingers or hand of the operator and moved about the spindle 12 to operate the machine.

When the operator engages the portion 21 of the lever and moves the latter downwardly or in a counter-clockwise direction, as shown in Fig. l, the gear 17 is rotated by reason of the engagement of the pawl 23 with the teeth 18 of the gear. It will be understood that the gear rides freely below the pawl 37 at this time as the carrier 36 is held against movement by engagement of the shoulder 61 of the detent 58 with the lug 35 of the carrier. This rotation of the gear causes rotation of the pinion 50 which by its engagement with the pinions 48 and 49 effects rotation of the feeding roll 44 and the stripper roll 45 to draw tape from the supply roll 14, as shown in Fig. 3.

The carrier 30 has heretofore been held against movement but when the actuating lever 21 reaches the position shown in Fig. 3, the edge 64 of the finger 63 strikes the edge 65 of the detent 58 and releases the lug 35 of the carrier from the shoulder 61 of the detent 58. At this time the carrier will be free to move with the actuating lever and the frictional resistance of drawing the tape from the supply roll will tend to cause the carrier to move with the actuating lever, and when the feed rolls are allowed to move downwardly they will no longer be rotated but will move with the gear 17. However, substantially simultaneously with the release of lug 35 from the shoulder 61 of detent 58, the lug 35 on the carrier will be engaged by the lug 66 on the actuating lever 21 so as to positively move the carrier with the actuating lever and thus discontinue the rotation of the feed and stripper rolls.

During the first part of the movement of the carrier 30 from the position shown in Fig. 3, this member is moved relatively to the arm 68, and the stripper members 73 are caused to project beyond the periphery of the disks 47 of the stripper roll .5, as shown in Fig. 4, and cause the dispensed portion of the tape to project forwardly in a substantially horizontal position. the rear end having been lifted from the stripper disks. Th s prevents the formation of a loop in the tape between the knife and the feeding and stripping rolls when the tape is engaged by the member 3t After a relatively small movement of the carrier, the teeth of the pinion 49 are engaged by a tooth 82 carried by the arm 68 so that the rotation of this pinion and also the pinions 48 and 50 will be positively prevented during further downward movement of the carrier 30.

Continued movement of the lever 21 in a counter-clockwise direction now effects movement not only of the carrier 30 but also of the arm 68 until themovement is stopped by engagement of the pin 70 with the upper end of the slot 69, as shown in Fig. 4.

As the actuating carrier and arm 68 move downwardly together the lower end of the plate 54 on the carrier engages the upper edge of the guard 78 and moves this member downwardly with the tape gripped between the guard and the member 54 at a point close to the periphery of the-stripping disks and roller 56. This carries the tape beyond the upper edge of the severing member or knife 76 which, as shown in Fig. 4, enters the space between the part 53 of the carrier and the roller 56 and severs the tape as illustrated.

When the lever 21 is released, the spring 25 tends to return it to its original position, shown in Fig. 1, against the stop 28. It will be understood that the stop 28 may be placed in any of the openings 29 in order to regulate the length of the dispensed strip. During the first part of this return movement the carrier 30 and arm 68 move in a clockwise direction with the lever until the arm 68 is stopped by the engagement of the lower end of the slot 69 with the pin 70 in the frame. The movement of this arm will then be stopped, and it will be understood that the guard will also have been moved upwardly by its spring 79, its upward movement being limited by engagement of the guard with the pin 83 to which the upper end of the spring 79 is secured.

Thereafter the carrier 30 will be moved to the position shown in Fig. 3 where its movement will be halted by engagement of the lug 35 with the pin 36 on the frame, as shown in Fig. 2. During this time the feed and stripper rolls will have been prevented from rotating but will move bodily with the gear 17, the latter being moved by engagement of the teeth of the pinion 50 with the gear. When, however, the movement of the carrier 3t is stopped by engagement of the lug 35 with the pin 36, the gear 17 will also cease to rotate and the arm 21 will continue in a counter-clockwise direction to the position shown in Fig. 1, during which movement the pawl 21 will ride over the teeth of the gear .17 which remains at rest. The parts are now in position for a subsequent operation, and the rear end of the severed portion of the tape will adhere to the upper end of the guard member with the forwardly projectiug portion in position to be engaged by the operator.
