George :M. Rickus, Wilton, Conn assignor to Hat Corporation of America, Fairfield, C0nn., a corporation of Delaware The present invention relates to apparatus for assembling and securing together the sides of. a. box and a transverse member extending .thereacross. Whilethe intion may be used for boxes of. varioustypes, it is particularly useful-in the makingof hat boxes.

Heretofore inmaking boxes such .as are usedfor hats and similar articles, it has been the custom toappl'y adhesive to theedges. of. the bottom orother transverse member and .insertthem between thesides. Thisrequires a certain amount of delay resulting frornthe. careful insertion of the coated edges and the necessary. time for the setting of the adhesive. Also, due to the possibility of the adhesive running out of the joint it has the tendency to produce. an unsightly box.

It is an object of the present invention. to provide an apparatus for. automatically andaccurately locating a transverse member within thewalls of. aboxandl secure it in position, said positionbeingat any point intermediate the ends of the sides'or at. the end of-the sides to form a bottom for the box.

It is another object of the invention to accurately secure a transverse member within the-sidewalls of the box by means of fasteningmeans passing therethrough and without the used cement .or glue.

A feature of the invention .residesin the complete and accurate control'of the component parts of the box during the assembly'and securing thereof. together by. the apparatus.

Another feature of the invention is the coaction between the plunger and the bottom supporting member whereby the action of the plunger. clamps the bottom to said supportingmember and movesthe bottom and supportingmemberto locate .the bottom in the desired position.

A further featured the invention is the provision of an automatic control system for completely and accurately'assembling and securing the sidewalls and bottom of the box and ejecting. the completely assembled structure so that the operator canreadily remove the same.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the drawings in which:

While the machine of the present invention may be used. to secure together the 'side walls. and a transverse member of a. box of various shapes with the transverse member. located. at. various pOS1t1011S"WilZ hi11pth. box, for

' the purpose. of:illustrating; the. inventionit wilLbe, described as. applyingaxbnttomz to, an octagonal haLbQx- .Aassshownrinafig. Lithezmachineqflomyrises atf'rarne 1,0 having a table 11 provided-withza well 12-10 receive the 2,696,612 Patented Dec. 14, 1954 sides A of the hat box. Extending above the table is, a pair of uprights 13connected at the upper end by a transverse member 14. Projectingabove the. transverse member 14 is an inverted V-shaped frame 15, the purpose of which will be more fully described.

As shown in Figs. 1 and 4', the well comprises anopening ,16 in the table which is shaped to receive the sidesA of the box which is formed of cardboard, paperboard, or other suitable box material scored at.A to forma plurality .of angularly related side panels A as..-shown in Figs. 7 and 9. The side supporting means or well is made up of a plurality of rigid strips 17' which are locatedflat the corners of the octagon. and .form supporting means for the angularly relatedside panels. oflthe box andinten mediate supporting ribs 18 located atsubstantially the midpoint of. each side panel. At the...botto rn of eachrib 18 is an inwardly extending lip 19 which forms astop for the sides when the same are inserted. into the well.

To facilitatethe inserting of the sides into the well, flared guide portions 21 are formed adjacentthe .end of each of .the ribs 17', 1 8'which enable the operatorto more quickly place the angularly related'sides in place.

In the center. of the well' is a bottom supporting member 20 which has its-edges spacedinwardly from the sides of the well; as showninFig. 4, and is normally yieldably held in the position shownin Fig. 2 to-engage theundersurface of a flared bottom B. as shown in Fig. 8, which may be made of cardboard, paperboard" or other suitable box. material, when the latterisinserted in the upperv portion of the side walls with'the flanges engaginglhelside walls as shown in Fig.2.

Whilethe bottom supporting member maybe urged to its normal position by any suitable means, it is herein illustrated. as beingmounted on a reciprocating piston rod 22' connected to a piston 22 ina cylinder 23. T0 insure accurate movement during its operation the. bottom supporting member 20 has a plurality of guide rods .24 connected to the undersurface and operating in guide bushings 25 carried by a subframe, 26 as shown in detail in Fig. 2.

As shown in Figs. 1 to 3 there is disposedabovethe table a plunger 27. for effecting-the assembly of the bottom and sides. In the illustrated form of the invention the plunger comprises a bottom engaging member 28 and a mounting plate or member 29 for the fastening devices of any suitable type. As herein illustrated they. are stapling devices. Each. of the members is mounted by means of. collars 30 on a reciprocatingpiston rod'31 connected to a piston32 operatingin the cylinder 33 carried by and extending between the transverse bar. '14 and the upper end of the inverted V' frame 15 so asto" be recipro'cated into and out of the well 12. The plunger is guided in its reciprocating movements by means of pairs of rollers 3'4 each adjustably mounted. at 35pm a projecting arm .3 6.-on. each. side of the plunger and riding in. tracks 37. extending between the table and transversefrarnernembcr. The tracks. are adjustable with respect. to the uprights 13 by .means of nut. and bolt adjustments 3.8..so. that anaccurately located and. steady-reciprocatingmovement. may be. had-on the plunger.

The plunger'is normally positioned in. retracted. position: as. shown. in Fig. l and.ha s.a.resilient .cus'hion 39 on the exterior of the mounting member 29'which engages the end of the cylinder and acts to cushion the plunger on its return stroke.v

The stapling. device. mounting member. has a, plurality of. stapling. devices 40 mounted: thereon. about the periphery asshown in Fig. 1. While stapling devices wh ch cut and form. staples fromspool's of wire may be. used, the devices hereinillustrated' areo'f' the Bostich typehaving. arms41. carrying preformed staples. notshown )1 which therefor 'by, .a-.;sj'pring.,.4 5 soasflfto-provide. a predetermined space between "the stapling head? andv the anvil to. permit the stapling head to be positioned on the exterior of the box while the anvil is positioned on the interior of the box within the flanges on the bottom when the plunger moves to the assembling and securing position. As shown in Fig. 4, either side of the supporting rib 18 is cut away at 46 to receive the stapling devices as they move to said assembling and securing position.

It will be noted that the stapling devices are arranged in the present preferred form of the invention with two stapling devices on each side of the box and are uniformly spaced so as to accurately secure the bottom to the sides. When the stapling devices have moved through the openings in the table and to a position shown in Fig. 3, the stapling heads will overlie the exterior of the box adjacent the lower portion thereof and the bottom engaging member will be disposed within the box and within the flanges on the bottom with the bottom accurately positioned at the bottom of the sides and the anvil on the edge thereof located within the flanges of the bottom so that the staple 47 will pass therethrough and be clinched over, when the stapling device is actuated, as shown in Fig. 7. To actuate the stapling devices, there are a plurality of operating means 48 carried by the subframe 26. In the illustrated form of the invention I provide one operating means for each side of the box, which means includes a striker head 49 which is of a length to engage the stapling heads of the pair of stapling devices overlying the side of the box. The striking head is carried by a piston rod 50 of a piston 51 operating in cylinder 52. The striking head is normally held in retracted position. A solenoid operated valve 53 is connected to the cylinder to cause the piston to be projected to actuate the striking heads. A guide plate 54 extends outwardly beyond the striker head and under the stapling head to guide the striking head as it is actuated to drive the staples.

In illustrating the operating system diagrammatically in Figs. and 6, I have shown a fluid system for the

cylinders

23 and 33 and for one of the stapling device operating means 48, all in normal position, it being understood that the stapling device operating means cylinders 52 are connected in multiple, as may be necessary. Any suitable fluid under pressure may be used to drive the pistons. In the preferred form of the invention, I employ air under pressure.

Fig. 5 shows a manually operated system in which air is pumped to a storage tank 55. Cylinder 33 is connected to the tank through a valve 56 so that pressure from the tank passes to the rod end of the cylinder and holds the plunger in retracted position. Cylinder 23 is connected to the tank 55 through a pressure reducing valve 57 so that a lower pressure than applied to cylinder 33 is applied to the head end of the cylinder 23 to hold the bottom supporting member in its normal raised position and yet permit it to yield under the action of the plunger. Cylinders 52 are connected through solenoid valve 53 to the tank 55, the valve being urged by spring 58 to a position that pressure is applied to the rod end holding the striker heads in retracted position. Valve 56 is manually turned to connect the head end of cylinder 33 to the tank. This causes the piston to move the plunger downwardly. The bottom engaging member 28 first engages the upper surface of the bottom B and clamps it against the supporting member 20. Continued pressure of the plunger overcomes the low pressure in cylinder 23, forces the member 20 and bottom downwardly relatively to the sides A for the full stroke of the plunger and accurately positions it at the bottom of the sides as shown in Fig. 3. The operator then closes the normally open switch 59 to the solenoid 60 on the valve which moves the valve and connects the head end of cylinder 52 to the tank and quickly projects the striker head to actuate the associated stapling heads. As soon as the switch is released, spring 58 restores the valve and the striker heads are returned to retracted position. The operator then returns valve 56 to the position of Fig. 5 and the plunger returns to normal position. As it moves upwardly, the member 20 will follow and raise the secured-together sides and bottom out of the well so that they may be readily removed therefrom.

Fig. 6 shows the operating system for an automatic control. In this system cylinder 33 is connected to the tank through a solenoid operated valve 56' which is normally spring urged to connect the rod end of the piston to pressure to maintain it in retracted position.

Cylinders

23 and 52 are connected to the tank in a manner similar to that disclosed in connection with Fig. 5. The operating circuit includes a normally open, manually operated switch 61 which is closed to energize solenoid 62 which will cause the valve to be shifted against the pressure of spring 63 to connect the head end of the cylinder to the pressure tank. At the same time it causes relay 64 to operate and close a holding circuit through the normally open contacts 65. The plunger will move down and position the bottom at the lower portion of the sides as described in connection with Fig. 5. When the plunger reaches the bottom of its stroke, it will close a normally open switch 59 to actuate the operator for the striking head which will be projected and clinch the staples. As the striking head moves to the end of its stroke it will open the normally closed switch 66 in the solenoid circuit and at the same time will open the circuit to the relay which will break the holding circuit. The

switches

59 and 66 are preferably microswitches so that the amount of movement necessary to close the switch 59 and open the switch 66 is very minute and hence the sequence of operation will be such that the switch 66 will not be actuated until the striking head is moved sufliciently to clinch the staple and immediately thereafter the plunger will start to rise and open the circuit at the switch 59.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
