i Claims. '1
This invention "relates to a device for applying a-spot of an adhesive-materialrsuch as glue to a paper wrapper.
The invention as illustrated herein, is shown as used'in connection with the wrapping'of nested stacks of milk bottle caps in the manner disclosed in the Goodwin Patent No. 2,266,547. The caps are then applied to the mouth of milk bottles by capping machines such as are shown in the Daniels Patent No. 2,068,165 and the Goodwin et al. Patent No. 2,325,163. These patents each show a capping machine having a cylindrical mag: azine adaptedto receive a stackof milk bottle caps from which they are automatically fed arid'applied to successive milk bottles as they leave a filling machine. In commercial practice the stacks of caps are wrapped {by rolling the same in wrapping paper in such away that'the wr'a'pper may be'sealed by a spot of adhesiveapplied to the wrapper adjacent one of the "corners thereof. Generally a definite number :of 'caps are wrapped in each wrappenand they are shipped and stored in wrapped stacks. Inloading the'capping machine a wrapped stack of caps is placed in the magazine with the corner of the wrapper beyond the sealing sp'ot extending out through a longitudinal slot in the magazine. The wrapper is removed by grasping this corner. and pulling on the same to break the seal and to un'roll the wrapper from the stack of caps, leaving the stack of caps in the magazine in condition for use. The caps are thus charged into the magazine without being touched by the operator; an important sanitary consideration in 'modern dairies. 5
Heretofore the adhesive was applied to the wrapping paper either by a small brush or by mechanism of the type such as :showndn 'ithe Dorsch Patent No. 2,156,804. Applying the adhesive by a brush is a-slow process and it is practically impossible to apply the-same amount of adhesive to successive sheets of wrapping vpaper. Either toomuch or too little adhesive is generally applied. When too vmuch -is applied the seal is not readily broken-after astack'has been inserted in the capping'machine magazine, and whentoo little is applied the seal frequently breaks "during handling. Prior known adhesive ap-plying mechamsms -are.rather complicated andare not too efficient in operation.
The principal object of the present invention is to provide an apparatus for applying spot'sof glue to-sheets of wrapping ,paper whichis simple and efficient in operation and which will always apply the same amount of glue" to successive sheets of wrapping :paper presented thereto.
Other and more specific objects of the invention will be apparent from the following specification and the accompanying drawings forming a part thereof wherein:
Fig. 1 is a plan view showing a wrapping table and my improved glue spotter associated therewith;
Fig. 2 is a front elevation thereof;
Fig. 3 is a central vertical section through our improved glue spotter showing the various parts thereof in their normal inoperative position;
Fig. 4 is a viewsimilar to Fig. 3 showing the various parts in the position they assume after the initial operative movement of the device; and
Fig. 5 is a view similar to Figs. 3 and 4 showing the device after it has been brought into contact with a sheet of wrapping paper to apply a spot of glue thereto.
Referring now to the drawing by reference characters, the numeral I indicates generally our improved glue spotter which when used in connection with the wrapping of nested stacks 'of bottle caps is usually associated with a wrapping table 2 as shown in Figs. 1 and 2. The table 2 has agroove or trough 3 extending from side to side thereof, and a pair of spaced transversely extending guide rails 4 and 5 adjustably secured to the upper surface thereof.
In wrapping stacks of bottle caps a rectangular sheet of wrapping paperB is first placed diagonally upon the table 2 with one corner 1 thereof beneath the glue spotter I, as shown in Fig. 1. A stack of caps, the length of the stack being equal to the distance between the rails 4 and 5, is then laid upon the wrapping paper over the groove or trough 3 and is pressed down thereinto. The lower corner 8 of the wrapper is then folded up over the stack, partially enclosing it, after which the opposite corners 9 and I6 of the wrapper are-folded in toward each other enclosing'the ends of the stack. The glue spotter l is then operated to place a spot of glue on the corner "I of the wrapper and the stack with the wrapper thus folded thereabout is rolled upon the table 2 until the spot of glue contacts the underlying wrapper and effectively seals it about the stack. The manner in which the wrapper is folded and rolled about a stack of caps is clearly disclosed in the aforesaid Goodwin Patent No. 2,266,547.
Our improved glue spotter l includes a glue pot H having its upper end closed by a cover l2 which is removably secured thereto by screw l3 extending upwardly from the 'pot ll through bayonet slots 14 in the *cover. It is supported ln operative relation to the table 2 by a bracket 15 having a vertical bore I6 therethrough in which the glue pot I I is slidably mounted. The bracket I is rigidly secured to either the table 2 or to any suitable support adjacent thereto.
A disc I'I having a transversely extending slot I8 formed therein is mounted within the upper end of the glue pot II upon an annular shoulder I9. Formed integrally with and projecting downwardly from the disc I? is a sleeve which acts as a guide for a valve stem 2I slidably mounted therein. A frustro-conical valve 22 which is pinned to the lower reduced end of the valve stem 2| is adapted to open and close a complementary shaped port 23 in a block 24 which is disposed in the lower end of the glue pot II. The valve 22 and the block 2d are made of hardened metal to resist wear due to operation. The valve stem 2| has an annular flange 25 formed integrally therewith a short distance below the upper end 26 thereof, and immediately below the flange 25 the valve stem l I has a slot 21 therethrough.
The upper end 23 of the valve stem and the flange 25 extend into an axial recess 28 in the lower end of a cam 29. The cam 29 has a cylindrical portion 30 which is slidably mounted in a centrally disposed aperture 3i through the cover I2. A knob 32 is pinned to the cam 29 as indicated at 33. A coiled spring 34 mounted in a bore 35 in the upper end of the valve stem 2I biases the valve stem 2I and valve 22 downwardly to close the port 23 and at the same time urges the cam 29 upwardly in the aperture 3|.
A pair of opposed bell crank levers 36 each having a vertical arm 31 and a horizontal arm 38 are pivotally supported in the slot I8 by pins 39. The horizontal arms 38 of the bell crank lever extend into the slot 21, through the valve stem 21, and the vertical arms 3'l of the bell crank lever are in contact with the frustro-conioal cam surface 40 of the cam 29.
A coiled spring II disposed about the glue pot I I between an annular flange 42, about the upper end thereof, and the upper surface of the bracket I5 normally urges the device upwardly in the bore It to the position shown in Fig. 3. A ring 4 3 adjustably secured about the glue pot II by a set screw 46 limits this upward movement of the device in the bore I6.
Operation In operation, glue in liquid form is placed in the glue pot I I beneath the disc II. This is done by loosening the screws I3, turning the cover I2 until the screw heads are in alignment with the enlarged ends of the bayonet slot I4 and then lifting the cover I2 and cam 29 01f by the knob 32. The disc I7 and the mechanism carried thereby are then removed and the glue inserted. These parts are then replaced. The spring 34 will normally hold the valve 22 down, closing the port 23 and preventing glue escaping. The wrapping paper is placed in proper position beneath the device and the knob 32 is depressed by the operator. This depresses the cam 29 which through the frustro-conical surface 40 spreads the vertical arm 3'! of the bell crank levers 36 and rocks the ends of the horizontal arms thereof upwardly. The upward movement of the ends of the bell crank arms 38 lifts the valve stem 2I and valve 22, from the position shown in Fig. 3 to the position shown in Fig. 4, opening the port 23 and allowing glue to flow into the annular space between the valve 22 and the port 23 and about the lower flattened end of the valve. Further depression of the knob 32 will move the device downwardly in the bore I6 against the upward pressure of the spring II, from the position shown in Fig. 4 to the position shown in Fig. 5 with the lower end of the device in contact with the wrapping paper. A spot of glue, the size of the lower end of the port 23 will then be applied to the wrapper. The operator then releases the knob 32 allowing the springs 34 and II to return the various elements of the device to the position shown in Fig. 3, ready for the next operation.
The device has been illustrated and described herein in connection with the wrapping of nested stacks of bottle caps, but that is only for the purposes of illustration as the device can be used equally well in many other environments where it is desired to successively apply spots of adhesive to articles.
From the foregoing it will be apparent to those skilled in this art that we have provided a simple and eflicient mechanism for carrying out the objects of our invention; and it is to be understood that we are not limited to the specific construction shown herein as various modifications may be made therein within the scope of the appended claims.
