No. 563,572 16 Claims. (Cl. 1212.5)

This invention relates to adhesive applying mechanisms and particularly to a novel and improved adhesive applying mechanism for use in a machine for lasting an end portion of a shoe, for example, of the type disclosed in US. Letters Patent No. 3,138,810, issued June 30, 1964, on an application filed in the name of Karl V. Becker. This type of machine is modified in some respects as disclosed in a copending application for US. Letters Patent Serial No. 458,616, filed May 25, 1965, in the name of Jules N. Allard. It will be understood, of course, that features of this invention are of broad utility and not limited to use in machines of the foregoing type or to the exact mechanical construction shown.

As is explained in the Allard application, machines of the type disclosed in the Becker patent are widely used for cement heel seat last and when so used may be provided with adhesive applying mechanism for applying thermoplastic adhesive to the heel end of the insole of each shoe during the assembling, backpart molding and heel seat operations. The Allard application discloses and claims such an adhesive applying mechanism having a single nozzle member, shaped generally to conform to the heel end of the insole of the shoe and mounted for movement down into the pocket formed by the lasting margin of the upper held upstanding by the molding band into contact with the insole for extruding molten thermoplastic adhesive onto the heel end of the insole just before the wipers are advanced and closed. While the arrangement provided by Allard operates in a satisfactory manner and has, in fact, been embodied in machines in actual shoe factory, use, it does have the disadvantage that a single nozzle is necessarily limited to use on only a relatively small range of sizes of shoes and last styles.

It is, therefore, an object of this invention to provide a novel and improved adhesive applying mechanism which overcomes this difiiculty and is universally useable with practically all sizes of shoes and different last styles.

With the foregoing object in view, and in accordance with the features of this invention, the herein illustrated adhesive applying mechanism which is shown as applied to a machine of the type disclosed in the Becker patent, comprises a pair of nozzles movable first from a position in which they are spaced from the bottom of the end portion of the insole of the shoe to a position in which they are close together and in engagement with the insole, at a location adjacent the end portion of the shoe. They are next movable laterally of the shoe away from each other to an extent determined by engagement with the lasting margin of the upper which is held upstanding around the end portion of the shoe by the molding band of the machine, and lengthwise of the shoe from the end portion thereof. Finally, they are movable in reverse directions back to their original positions. Means are provided for effecting such movements of the nozzles as well as means for extruding molten thermoplastic adhesive through the nozzles and onto the insole during the lateral lengthwise movements of the nozzles, immediately after the molding band has ben operated and before the wipers are advanced and closed. More particularly, the means for extruding adhesive includes a melt body connected to the nozzles and mechanism for feeding the leading end of a solid rod of adhesive into the body to cause molten adhesive to be extruded from the nozzles. Each nozzle is provided with a normally closed valve member adapted to be opened in response to engagement of the nozzle with the bottom surface of the insole. Preferably, and as herein illustrated, fluid pressure operated power means are provided for effecting the several move ments of the nozzles and the means for effecting longitudinal and lateral movements thereof are arranged to be set in operation by an initial operation of the adhesive extruding means thereby to cause a quantity of adhesive to be extruded through the nozzles while they are located adjacent the end portion of the shoe and before they commence their lateral and lengthwise movements along the bottom surface of the insole.

The above and other objects and features of the invention will appear in the following detailed description of the embodiment illustrated in the accompanying drawings, and will be pointed out in the claims.

In the drawings: I

FIG. 1 is a view in side elevation of a portion of a shoe machine of the type disclosed in the above mentioned Becker patent provided with an improved adhesive applying mechanism embodying the features of this invention;

FIG. 2 is a plan view of that portion of the shoe machine and adhesive applying mechanism shown in FIG.l;

FIG. 3 is a view in side elevation and on an enlarged scale of the operating elements of the shoe machine and showing one of the adhesive applying nozzles forming part of the improved adhesive applying mechanism;

FIG. 4 is a view similar to that of FIG. 3, but showing the adhesive applying nozzle in a different position assumed during the operation of the machine;

FIG. 5 is a view similar to that of FIG. 4, but showing the operating elements of the shoe machine and the applying nozzle of the adhesive applying mechanism in other positions assumed during the operation of the machine;

FIG. 6 is a plan view of the heel end of a shoe with the two adhesive applying nozzles diagrammatically illustrated thereon and shown in two different positions assumed during the operation of the machine, one in broken lines and the other in solid lines;

FIG. 7 is a view in perspective and partly in vertical section of a portion of the heel end of a heel seat lasted shoe, and

FIG. 8 is a pneumatic diagram.

Referring to these drawings and particularly to F IGS. 1 and 2 thereof, as suggested above, the machine which is partly illustrated therein is similar to that disclosed in the patent and also in the copending application referred to above. Thus, FIG. 1 corresponds quite closely to FIG. 2 of the Becker patent and also to FIG. 1 of the Allard application and shows a portion of one of the assembling and backpart molding stations of a machine of this type which has been modified by omission of the tacking mechanism and by the provision of the improved adhesive applying mechanism of the present invention. Accordingly, the illustrated machine has a main frame member, indicated generally by the reference character 20, with which there is associated a shoe supporting jack 22, mounted for vertical movement by means of a fluid pressure actuated piston, not shown, to press the heel end of a shoe S, comprising a last L with upper materials U, C, P, and an insole I, FIGS. 1, 3, 4 and 5, assembled thereon against a shoe rest or holddown 30, in the manner explained in detail in the Becker patent. Also associated with the frame 20 and slidably mounted thereon is a heel band carriage 40 provided with a heel molding band 42, corresponding in construction and function to the heel molding band 156 illustrated in FIGS. 6 and 12 of the Becker patent and described in columns 5 and 6 thereof, and wipers 50, 52, FIG. 2, corresponding to the wipers 216,

3 220 in FIG. 4 of the Becker patent and described in columns 7 and 8 thereof.

For advancing the heel band carriage toward the heel end of a shoe on the jack, thereby to cause the heel band 42 to embrace and to shape the upper materials to the heel end of the last, a fluid pressure actuated piston 60, in a cylinder 62, FIG. 8, is provided, this piston having a piston rod 64 which is operatively connected to the carriage 40 by means of a lever 66 and a link 68, FIG. 1. The wipers 50, 52 are advanced and closed by fluid pressure actuated piston 70, in a cylinder 72, see FIG. 8, acting through various earns, rollers, etc., as described in detail in the Becker patent.

The fluid pressure system, diagrammatically illustrated in FIG. 8 comprises only that portion of the fluid pressure system associated with one of the backpart molding and assembling stations of a machine of the type disclosed in the Becker patent, see FIG. 16 thereof, which is involved in the operation of the heel molding band carriage 40, the wipers 50, 52 and the various operating elements of the improved adhesive applying means which, a will presently appear, operates immediately after the heel molding band carriage has been moved to cause the heel molding band to embrace the heel end of the shoe, thus shaping the heel portions of the upper materials to the heel end of the last, and just before the wipers are advanced and closed.

As will be understood by reference to the Becker patent, an automatic operating cycle of this station is initiated in response to the actuation of a treadle operated valve, not shown, and during this operating cycle the jack 22 is first elevated from the position shown in solid lines in FIG. 1 to the position shown in dotted lines in FIG. 1 and in solid lines in FIGS. 3, 4 and 5. Next, the heel molding band is operated to shape the upper materials to the heel end of the last. In the arrangement previously provided in the machine illustrated in the Becker patent, the wipers would now be advanced and closed and the operating cycle completed automatically. For the purposes of this invention, and as is the case in the machine of the Allard application, just before the wipers are advanced and closed, a band of thermoplastic adhesive is applied to the heel end of the insole in the following manner and by means of the improved adhesive applying mechanism about to be described.

Referring to FIGS. 1 and 2 of the drawings, there is slidably mounted on the heel molding band carriage 40 an open box-like frame member indicated generally by the reference character 100 having a bottom wall 102, FIG. 2, oppositely facing side walls 104, 106 and a rear wall 108. Connected to the rear wall 108 of the frame member 100 is the rod 110 of a piston 112, FIG. 8, contained within a cylinder 114, FIG. 1. At the beginning of the operating cycle, fluid under pressure admitted to the left hand end of cylinder 114, FIG. 1 (right end, FIG. 8) through a conduit 120 and check valve 122, holds the frame member 100, together with other parts carried thereby in the position shown in FIG. 1.

Supported on the frame member 100 by means of a bracket 126, is an elongated melt body 128 adapted to receive and melt the leading end of a solid rod of thermoplastic adhesive R, fed into the melt body through an inlet 130 at one end thereof, by mechanism to be described below, and to extrude molten thermoplastic adhesive through a pair of flexible conduits 132, 132 connected to the opposite end of the melt body. This melt body is provided with a longitudinal passageway, not shown, in which the melting takes place as the result of heating of the melt body by means of suitable electric heating devices, not shown.

The bracket member 126, in turn is carried by an elongated supporting arm 140 which itself is secured to the rear wall 108 of the frame member 100. Supported on this arm, by means of

twin posts

142, 144 is a tube-like guide member 150 on which there is slidably mounted a 4 feed block 152 carrying a pair of

feed dogs

154, 154, FIG. 1. These feed dogs extend through slots 155 in the guide member and are adapted frictionally to grip the solid rod R of adhesive which passes through the guide member 150 from a supply roll 156 and to feed the rod into the melt body 126 when the block 152 is moved to the left, FIGS. 1 and 2. For thus moving the feed block, the rod 160 of a piston 162, FIG. 8, is connected thereto. This piston is contained within a cylinder 164, pivotally mounted on a portion of the bracket 140. FIGS. 1 and 2.

Suspended on the side walls 104, 106 of the frame member 100, by means of parallel links 170, 172, 174 and 1'76, FIG. 2, is a platform and pivotally mounted on cars formed integrally at one end of this platform are a pair of bellcrank levers 182, 184. Connected to one arm of each of these two bell crank levers, by means of pin and slot connections, FIG. 2, is a cross head 186 carried by the outer end of the rod 188 of a piston 190, FIG. 8. This piston is contained within a cylinder 192 mounted on the platform 180, FIG. 1. Secured to the other arm of each of these two bell crank levers, by means of screws 194, 194 is an adhesive dispensing nozzle indicated generally by the reference character 200. An insulating block 196 is interposed between the nozzle and the arm, as shown in FIG. 3.

These two adhesive dispensing nozzles are of identical construction and are mirror images of each other, one right hand and the other left hand. Each nozzle comprises a block 202 provided with a vertical bore 204 in the lower end of which a tubular extension 206 is secured by means of a set screw 208, FIG. 4. At its lower end, the bore of the tubular extension is provided with a discharge orifice 210 and a shoulder 212 against which a valve member 214 is normally held by means of a coil spring 216. This spring is interposed between the upper end of the valve member and a closure plug 218 threaded into the upper end of the bore 204, FIG. 3. The valve member 214 is provided with a stem portion 220 which projects outwardly through the discharge orifice 210 when the nozzle member is elevated away from the bottom of a shoe in the machine, FIGS. 3 and 5, and which lifts the valve member away from its seat when the nozzle member is in engagement with a bottom of a shoe, FIG. 4. The tubular extension 206 is relieved at its lower end, as shown in FIGS. 3-6, see surface 216. Associated with the block 202 are

electric heating elements

222, 222. The flexible conduits 132, 132 are in communication with the

vertical bores

204, 204 of the two

adhesive dispensing nozzles

200, 200 as shown in FIG. 2.

For moving the platform 180 in a vertical direction thus to lower the adhesive dispensing nozzles into engagement with the bottom of the heel end of a shoe in the machine, there is connected to the two links 170, 174 a tie rod 230 which, in turn, is connected to the rod 232 of a piston 234, FIG. 8, contained within a cylinder 236, FIG. 2.

Referring to FIG. 8, when during the automatic operating cycle of the machine with which the adhesive applying mechanism is associated the heel band carriage 40 is advanced as a result of the admission of fluid under pressure to a conduit 300, thus to cause the heel molding band 42 to shape the upper materials around the heel end of the last L, see FIGS. 3 and 4, this pressure fluid also flows through a pilot operated valve 302, conduit 304, sequence valve 306, a manually operated valve 308 into the right hand end of the cylinder 236 (left hand end as viewed in FIG. 2). Pressure fluid also flows through a branch conduit 310 to shift a pilot operated valve 312 so as to connect another conduit 314 to exhaust. The piston 234 is now moved to the left (to the right in FIG. 2), as fluid exhausts from the cylinder 236 through the conduit 314, a check valve 316 and the valve 312, thus lowering the platform 180, FIG. 1, and bringing the

nozzle extensions

206, 206 of the

nozzles

200, 200 into engagement with the extreme heel end of the insole I, as

shown in broken lines in FIGS. 4 and 6. As a result of this engagement withthe insole, the

nozzle valves

214, 214 will be opened, see solid line nozzle in FIG. 4.

A cam surface 320 on the link 170, FIG. 1, now engages a roller 322, associated with a valve 324 and shifts this valve, against the resistance of its return spring, to a position to admit pressure from a pressure supply conduit 326 to the lower end of a pilot operated valve 328, thus shifting this valve to a position to admit pressure fluid to a conduit 330 and to connect another conduit 332 to exhaust. As shown in FIG. 8, these two last mentioned conduits are connected to the cylinder 164 and the piston 162 in this cylinder will now be moved to the left causing the feed block 152, FIG. 1, to move to the left and feed the leading end of the rod R of thermoplastic adhesive into the melt body 126 so that molten adhesive is ex-, truded from the melt body through the hoses 132, 132 to the

nozzle members

200, 200 and out through the

discharge orifices

210, 210 of the

nozzle extensions

206, 206. After a short initial movement of the block 152, a cam member 334 carried thereby engages a roller 336 associated with a valve 338.

The valve 338 is now shifted, against the resistance of its return spring, to a position to connect a conduit 340 to a conduit 342 thus causing a pilot operated valve 344 to be shifted to a position to connect a conduit 350 to the supply conduit 326 while a conduit 352 is connected to exhaust. These two conduits are associated with the

cylinders

114 and 192, FIG. 8, and

pistons

112 and 190 will now be moved to the right (to the left in FIGS. 1 and 2) causing the nozzle members to be moved to the left (FIGS. 1 and 2 and downwardly, FIG. 6) and to be swung outwardly, away from each other and laterally of the shoe, so that they follow curved paths as determined by the engagement of their

tubular extensions

206, 206 with the lasting margin of the upper materials now held upstanding around the heel end of the last by the action of the heel molding band 42, see FIGS. 3 and 4. Such movement of the nozzle members continues until the roller 354 of a valve 356 rides up on the surface ofa cam 35S, adjustably mounted on the heel band carriage 40 by means of a screw 360.

The valve 356 is now shifted against the resistance of a return spring to a position to admit pressure fluid from the conduit 310 to the upper pilot of the valve 302, thus shifting this valve to a position to connect

conduits

304 and 310 to exhaust through a conduit 362, and valve 308. Valve 312 is now shifted by its spring to a position to admit pressure fluid, from supply conduit 326, to the left hand end of the cylinder 236 (right hand end FIG. 1) through the conduit 314 and a flow control valve 364 and also to two

pilot lines

366, 368. As the piston 234 begins to move in a direction to elevate the platform 180 and the

nozzle members

200, 200, the cam 320 leaves the roller 322 so that the valve 324 is returned to its original position by its spring. Valve 328 is now shifted, by pilot pressure fluid in the line 366 to a position to connect conduit 330 to exhaust and to admit pressure fluid to the conduit 332. Piston 162 now moves to the right to return the feed block 152 to its original position.

Pressure fluid in line 368 now shifts the valve 344 to a position to connect conduit 350 to exhaust and to admit pressure fluid to the conduit 352. The

nozzle members

200, 200, wil now be retracted and brought together by movements of the

pistons

112 and 190 to the left (to the right in FIGS. 1 and 2), thereby returning the operating elements of the adhesive applying mechanism to their starting positions.

As the frame member 100, which carries the adhesive applying

nozzles

200, 200, the melt unit 126, etc., begins its movement by the piston 112, the roller 354 rides down off of the cam 358 and the valve 356 is returned by its spring to a position to connect the upper pilot of the valve 302 to exhaust. This valve, however, remains in its shifted position at this point in the operating cycle so that pressure fluid is admitted from the conduit 300 to a con duit 370 which leads to the wiper operating cylinder 72, through a cam operated valve 372 having a roller 374 and a flow control valve 376. When the platform has been fully elevated by the piston 234, a cam surface 378, on the link 174, engages the roller 374 thus shifting the valve 372 to a position to admit pressure fluid to the cylinder 72. The wipers are now advanced and closed as a result of movement of the piston 70 to the right (to the left in FIG. 1).

As these advancing and closing movements of the wipers are completed, a cam 380, movable with the wiper operating mechanism, FIG. 1, engages the roller 382 of a valve 384, associated with the fluid pressure operating system of the machine. As a result of the opening of this valve, the operating cycle of the machine, which had been previously interrupted during the operation of the adhesive applying means, is continued and completed. During the completion of the operating cycle, the wipers and heel molding band are retracted and the shoe jack is lowered to release the shoe. Prior to the completion of the cycle, pressure fluid is momentarily admitted to the lower end of the valve 304 through a conduit 390, by means of a valve associated with the fluid pressure system of the machine, thus returning the valve to its initial position.

As is explained above, the lateral and lengthwise movements of the adhesive applying

nozzles

200, 200 are started as a result of an initial movement of the rod feed block 152. Accordingly, a quantity of molten adhesive, A, A is extruded from each nozzle before it begins to move and these quantities of adhesive tend to flow toward each other slightly, as indicated in FIG. 6, to provide a slight excess of adhesive for bridging the gap between the nozzles when the lasting margin of the upper materials is subsequently wiped inwardly over and pressed against the insole. Now, as the nozzles are moved laterally and lengthwise of the heel end of the shoe, they follow the marginal contour of the heel end of the shoe as determined by the lasting margin of the upper materials held upstanding by the molding band, as indicated in FIG. 6 in which bands of adhesive are indicated in dotted lines. In this figure, the upstanding lasting margin of the upper materials is shown in full lines while the inner edge of the lasting margin after it has been wiped inwardly over the heel end of the shoe is indicated "by means of dash lines with a second dotted line indicating the inward extent of the adhesive slightly beyond the upper, see also FIG. 7. Thus, this improved adhesive applying mechanism is universally useable with practically all sizes of shoes and different styles of lasts. As will be readily apparent, the extent of lengthwise movement of adhesive applying nozzles may be varied to accommodate different sizes by suitable adjustment of the cam 358 by means of the hand screw 360. Just as soon as the nozzles are elevated from engagement with the bottom of the shoe, the

valves

214, 214 associated therewith will be closed and also the feeding of the rod R will be terminated as movement of the feed block 152 is reversed. Accordingly, pressure of the molten adhesive within the melt body 148, flexible conduits 132, 132, and

nozzles

200, 200 is reduced and leakage of adhesive around the nozzles is eliminated.
