16 Claims.

This invention relates to a machine for dispensing and for applying to an article such as a package, adhesive strips or sheets, for example, normally tacky or pressure-sensitive adhesive tape which is known as Scotch tape.

Prime objects of the invention are to provide a machine which shall embody novel and improved means for dispensing pieces of tape of predetermined length into a predetermined position to be engaged by a portion of an article, such as a package, upon movement of the latter in one direction, and means operable by and upon said movement of said article for applying said piece of tape to the article; and to provide such a machine wherein the last-named means shall also actuate the means for dispensing the tape, whereby the machine shall be simple and inexpensive in construction and operation and shall be reliable and durable.

Another object is to provide a machine of this character which can be manually operated by a relatively unskilled operator and with a minimum of attention and physical effort.

A further object is to provide in a machine of the general character described novel and improved means for withdrawing in succession predetermined lengths of tape from a roll or strip, for severing pieces of the tape from the roll or strip. and for projecting and holding the severed pieces in position to be engaged by an article t which the piece of tape is to be applied.

Other objects, advantages and results of the invention will be brought out by the following description in conjunction with the accompanying drawings in which Figure l is a top plan view oi' a gummed tape applicator embodying my invention, with portions broken away and shown in section for clearness in illustration.

Figure 2 is a vertical sectional view on the line 2-2 of Figure l.

Figure 3 is a transverse vertical sectional view on the line 3 3 of Figure 2.

Figures 4 and 5 are horizontal sectional views on the lines 4-4 and 5 5, respectively, of Figure 2, and

Figure 6 is a fragmentary perspective view of one end of a package or box having a piece of adhesive tape applied thereto, showing the manner in which the machine of the invention applies a piece of adhesive tape.

Speciiically describing the illustrated embodiment of the invention, the gummed tape applier includes a case A that may be mounted on any suitable support in any suitable manner. but is shown as set into a hole I in the top of a table or like support B. The casing has a top wall 2 disposed slightly above the top side of the support B and having an opening 3 through which the tape to be applied is projected and an applier for the tape is operated.

Within the casing are suitable supports, in the present instance rollers 4, for a roll C of adhesive tape, the rollers being shown as mounted on cap screws secured in bosses 6 in the casing, the heads 6 of the cap screws serving to hold the roll of tape on the rollers between said heads and the ends of the bosses.

One type of adhesive tape with which my applier may be utilized is what is known as "Scotch tape which generally comprises a strip of crepe paper. cellophane, or the like to one side of which is applied a normally tacky or pressuresensitive adhesive. Tape can be unwound from the roll without transfer or osetting o! the adhesive and the adhesive may be caused to adhere to a surface by simple application of pressure and without activation of the adhesive as by water,

solvents or heat. The strip I of adhesive material is unwound from the roll C and passes downwardly and then upwardly around a guide roller B and between a guide spring 9 and a block III, whereby the tape may be guided and pulled upwardly through the opening 3 in the top wall of the casing. The roller 8 is mounted on a stud II and is held thereon by a cap screw I2. The spring Il is mounted on a stud I3 and the block III is mounted on an angle bracket I4 which is secured by screws I5 to one wall of the casing.

Within the casing is also arranged a means generally designated D for feeding the strip l of adhesive material so as to locate the free end portion thereof in a predetermined position to be engaged by an article such as a package or box E upon movement of the latter in one direction as shown by the arrow in Figure 2. Cooperating with the feeding means D is a means F for severing a piece ot the adhesive material from the strip, and means G also is provided for applying the severed piece of adhesive material to the box E. As shown. preferably this means G also serves as the actuator for the feeding means D.

The feeding means comprises a carrier I6 which m in the form of a hat bar and has a longitudinal slot Il through which passes the stud II so that the carrier is slidably reciprocable. One end oi the carrier has a head Il which at its lower limit of movement is pressed into adhesive contact with the strip I at the side thereof opposite the block lil and during its upward movement pulls the strip from the roll C. At its upper limit of movement the head I8 holds the free end of the strip 1 in position to be engaged by the box E.

The means for actuating the carrier IB includes a gear I9 mounted on a stud 2li in the casing and rigidly connected to a crank arm 2i which is pivotally connected at 22 to the carrier i6. Meshing with the gear lil is a gear segment 23 which rotates about a stud 24 and is rigidly connected to the hub 25 of a bifurcated presser lever 26 between the arms of which is a presser roller 21. The lever 26 normally is influenced by a spiral spring 28 so as to locate the roller 21 in juxtaposition to and at the side of the free end of the strip 1 opposite that against which the box E is moved. A stop stud 28 limits the movement of the lever 26 under the influence of the spring 28.

In operation of the machine so far described the parts normally are in the position shown by solid lines in Figure 1 with the end of the adhesive strip projecting through the opening 3 as indicated at X and with the end portion of the strip severed from the main strip at Y. The operator pushes the box E to which adhesive tape is to be applied along the top of the casing Ain the direction of the arrow as shown by solid lines in Figure 2 whereupon the adhesive tape is pressed between the roller 21 and the end of the box so that the tape is adhesively attached to the box. Then the operator continues to move the box in the same direction against the influence of the spring 28 which pulls the piece of tape oil. the head i8 of' the carrier and causes the roller 21 to be moved by and with the box until the roller is forced downwardly through the opening I as shown by dot and dash lines in Figure 2. At the same time, the roller rolls over the piece of adhesive tape so as to securely attach the latter to the box.

During this operation, the carrier iB has been moved downwardly by the gear segment 23, gear i9 and crank arm 2| so as to bring the head IB of the carrier into contact with the tape at the side of the tape opposite the block iii. The tape thus is adhesively attached to the carrier.

Preferably the block ill is of rubber to facilitate the operation.

When the box is lifted by the operator, the lever 26 will be swung in the other direction under the influence of the spring 28 into its normal position. At the same time, the carrier will be moved upwardly with the strip 1 attached thereto so as to again project the end of the strip through the opening 3.

In accordance with the invention, the strip is severed at this time as shown in Figure 2. The severing means includes a lever Ill which is pivotally mounted intermediate its ends at 3l on the casing and has a knife blade I2 at its upper end to cooperate with a slotted cutting block 33. The lever 30 has a lateral arm M that is connected by a spring 35 to an arm 26 on the carrier I6, said spring serving to actuate the lever 21| in each dlrection as the carrier I6 moves to its respective limits of movement.

More particularly the knife blade normally is in cutting relation to the block 33 so as to sever the strip as shown in Figure 2. As the strip is applied to the box E and the carrier il is lowered, the lever lil is held against movement by engagement of a roller 21 onJ the lever In with a stop block 3B on the carrier, but when the carrier reaches its lower limit of movement, the block 38 is moved out of abutting relation to the roller 31 so that the roller may swing above the block and permit movement oi the lever I0 under the influence of the spring 3i in such a manner as to withdraw the knife blade from the cutting block and the strip as shown by dot and dash lines in Figure 2. Movement of the knife lever is limited by engagement with the stud I3. Then upon movement of the carrier upwardly, the lever 30 is held in its inoperative position by engagement of the roller 31 with the opposite side oi the stop block I8 until the carrier has reached its uppermost; or normal position, whereat the block is out of abutting relation to the roller 31 so that the knife lever 20 may be swung by the spring I5 into operative position with the blade 32 entering the slot of the block Ill so as to cut the strip and sever a piece of predetermined length therefrom as shown by solid lines in Figure 2.
