CLENCI-IING AND GUIDING MECHANISMv FOR STAPLING-IVIACHINES.
Specification of Letters Patent.
Patented May 2, i916.
Application filed October 15, 1915. Serial No. 55,915.
To all whom it may concern:
Be it known that I, HENRY WEBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Clenching and Guiding Mechanism for Stapling-Machines, of which the following is a specification.
This invention relates to stapling machines such as are used for forming 'heavy paper cartons and other devices, and is especially adapted for fasteningtogether the over-lapping flaps of a carton blank to form continuous side walls for a carton.
The invention consists of a novel combination and arrangement of parts set forth in the following specification, shown in the accompanying drawings, and more particularly pointed out in the appended claims.
In the drawings-Figure 1 is a fragmentary plan View of a portion of a cartonforming machine with the present invention applied thereto. Fig. 2 is a fragmentary side elevation of a portion of a carton-forming machine showing the pres ent invention attached thereto; and Fig. 3 is a fragmentary perspective of the mechanism shown in Figs. 1 and 2.
Referring to the above figures, the numeral 1 represents the table top of a cartonforming machine.
The numeral 2 represents a carton in the process of formation. The carton is folded as shown in Fig. 3 of the drawings, and the lower continuous fold 3 is placed fiat upon the table top and the upper flaps 4. and 5 are folded over on top of the lower fold 3 with portions of the margins of the flaps over-lapping each other. To form a carton these over-lapping margins must be fas tened together so that the complete device, when removed from the machine and expanded, will form continuous side walls for the carton.
The margins are secured together by driving staples inwardly through the overlapping portions of the flaps and in order to prevent these staples from piercing the lower fold 3 of the carton, and to clench them on the inner side of the lower flap *1, it is necessary to support a clencher plate 6 Within the carton as it is being formed.
This clencher plate must be so supported that it will not interfere with the continuous passage of cartons through the machine. To permit this free passage of the cartons, the plate 6 should have its lateral edges and 1ts upper and lower surfaces entirely free from obstruction. To accomplish this result in the present invention, the clencher comprises a supporting strip 7 made of a comparatively thin sheet of metal and extending longitudinally of the stapling machines. The clencher plate ,6 is an integral portion with the strip 7 and eX- tends laterally from the rear end of the extends laterally from the strip at the forward end thereof. A second portion 8 extends laterally from the rear end of the strip 7 in the same direction as the plate 6. The complete clenching device there fore, as shown in Fig. 1, consists of an elongated plate with the central portion largely removed, leaving a connecting strip only along one side of the plate.
In the drawing, the lower portion only of the stapling head is shown. The stapling head itself may be of any approved con struction and in the form represented in the drawing, a reciprocating plunger 9 is carried in guides 10 and is arranged to force staples downwardly into the work directly beneath, in a manner well-known in the, art. Secured to the stapling head, and extending therefrom in a direction longitudinally of the table, and toward the end of the table from which cartons are fed to the machine, is a bracket 11 which has a lower longitudinal bar 12 carryinglaterally projecting rollers 13. Near the end of the bracket 11 adjacent the stapling head, is secured to the under side thereof, the laterally projecting portion 8 of the clencher. As shown in Fig. 2, the lower portion of the bracket is out out to form a slightly inclined supporting surface, so that when the clencher is secured in place the strip 7 will be slightly inclined downwardly toward the clenching end thereof. At the end of the strip 7 where it joins the clencher plate 6, a slight bend is formed in the strip to compensate for its inclination and to bring the plate 6 into horizontal position beneath the clencher head.
T o assist in properly guiding the flaps of the carton into position to be secured together, an automatic flap separator 14 is provided, which comprises a pair of metal straps 15 having the rear portions 16 thereof lying in vertical planes and being twisted through an angle of 90, (as shown at 17 in Fig. 1) to bring the forward portions 18 into a horizontal plane. These straps are spaced apart and have their forward ends hinged at 19 to the rear edge of the clencher plate 6. The rear portions 16 of the straps 15 have a series of rollers 20 extending from one of the straps to the other and journaled for rotation therein. The extreme rear ends of the straps 15 are pointed, as shown at 21, to enable them readily to enter between the lower fold 3 of the carton and the over-lying flaps.
A guide plate 22 is secured to the bar 12 of the bracket 11 and extends outwardly therefrom as shown in Figs. 2 and 3, over the portion 8 of the clencher. This guide plate 22 has an angular portion 23' which is secured to the side of the bar 12, by any suitable means, for holding the plate in position. The plate is inclined downwardly toward the front of the machine in order to direct the uppermost flap of the carton downwardly into position beneath the stapling head. A roll 24 is carried by an arm 25 pivoted to the bracket 11 by a pivot bolt 26. The roll 24 is connected by mechanism not shown, with the starting clutch for the stapling head, in order that the stapling head may be automatically thrown into operation whenever a carton is fed beneath this roll.
The cartons are fed to the stapling mechanism by endless chains 27 traveling in grooves 28 in the top of the stapling machine table. The chains 27 are provided with a series of upstanding lugs 29 arranged to bear against the rear portions of the cartons as they are fed to the machine. The table also carried adjustable guides 33 to position the cartons beneath the stapling head. A suitable support 30 for the staple clenching portions of the machine is provided.
The operation of the device is as follows: A carton folded, as shown in Fig. 8, is placed on the portion of the table top back of the automatic flap separator 14, and between lateral guides, not shown. As soon as the chains 27 have traveled a sufiicient distance to bring a pair of stops 29 into contact with the rear edge of the carton, it is carried forwardly with the chains into position to be operated upon. As the carton is moved forwardly it is first met by the pointed portions 21 of the automatic flap separator 14. These portions enter between the lower fold 3 and the upper over-lapping flaps 4 and 5. In this way the flaps are rollers 13. The carton continues to move in this position until the forward edge of the flap 5 contacts with the guide plate 22, when it is presed downwardly and directed beneath the wheel 24. In this position, the flap 5 raises the wheel 24 and automatically starts the stapling mechanism to operating in a manner well-known in the art. The margin of the flap 4 is guided beneath the supporting portion 8 of the clencher plate by the lower edge of the bracket 11 beneath which the flap is traveling. As shown in Fig. 3, the extreme edge 32 of the flap 4 does not extend far enough to reach the strip 7 of the clencher. As the carton is moved forwardly, therefore, the front portion of the flap 4 is free to be guided on to the upper surface of the clencher plate 6 by the forward portions 18 of the automatic flap separator 14, which are hinged to the rear edge of the plate 6 and which support the flap 4 on their upper surfaces. In this way the overlapping portions of both flaps 4 and 5 are brought together on the upper surface of the clencher plate 6 in a position directly beneath the stapling head where they are secured together by staples forced downwardly from the stapling head and firmly clenched on the inner surface of the fiap 4 by the clencher plate 6.
It will be seen that the construction described provides a simple means for supportinga clencher plate within the interior of the carton blank and that there are no upwardly or downwardly projecting portions secured to the clencher plate, which is thus left with both its upper and lower surfaces and all of its lateral edges entirely unobstructed, so that the cartons may be fed continuously through the machine.
