Filed Feb. 15, 1926 Patented Jan. 19, 1932 PATENT OFFICE- UNITED STATES JOHN CHARLES BALLETTI, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR'TO AMERICAN CAN COMPANY, OF SAN FRANCISCO, CALIFORNIA, A. CORPORATION OF NEW JERSEY BODY BLANK SORTING APPARATUS FOR PLATE SLITTING MACHINES Application filed February 15, 1928. Serial No. 88,220.
The present invention relates to a sorting or segregating apparatus for articles and is adapted for separating perfect from imperfect articles or objects. Sheets of tin plate are trimmed andslit into blanks from which can bodies are formed, and the surface of the plate often contains rough spots or other imperfections, which imperfections, when the sheet is out, are located in one or more of the body blanks.
This particular invention has for its ob jects to provide an apparatus for segregating or sorting the desirable from undesirable or imperfect slit portions or body blanks cut from a trimmed plate. Another important object of the invention is to provide a body blank segregating or sorting apparatus adaptable for use in connection with slitting apparatus as now employed; one wherein the body blanks as 'cut and discharged from the slitter may be selectively sorted, at the will of the operator, in accordance with their desirability of use for the purpose intended. A further object is to provide a control mechanism for a sorting apparatus adaptable for operation from a point distant from the location of the sorting apparatus, enabling the sheet feeder of the slitting apparatus, on observing any waster spot or imperfection in 30 the sheet as fed, to set the sorting apparatus to discard the slit portion or body blank containing the imperfection from the remainder of the slit portions or body blanks cut from the same sheet; to provide means for retaining the sorting apparatus in its set position until such time as the same is released to return to normal position by the passage'over one surface thereof of the directed slit portion or body blank.
With the above-mentioned and other objects in View, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrific- 50 ing any of the advantages of the invention.

Fig. 7 is a wiring diagram. for the apparatus controlling the directing means.
In the drawings, wherein like characters of reference designate corresponding parts throughout the several viewsthe numeral 1 indicatesa frame, the same being provided with runway surfaces or bed plates 2 and 3, illustrated as arranged at right angles to each other. At the free end of the bed plate 2 is stationed the operator employed to feed the tin plate sheets A onto said bed plate with one edge against the straight edge or aligning device 4, disposed at substantially right angles to the bed plate 3. Adjacent its juncture with the bed plate 3, the bed plate 2 has extended transversely thereove'r, one over and the other below the same, rotatable shafts 5, intergeared at 6, and mounted in their respective bearings 7. The shafts 5 each carry the well known type of feed and trimming rolls or cutters 8, arranged in cooperating pairs,
and one of the shafts, in the present embodi ment being the lower shaft, is provided with a power wheel or pulley 9, preferably operated in the direction of the arrows-Figs. 1 and 2.
The sheets A, positioned as in Fig. 1, when fed between the feed and cutter rolls 8 are trimmed and are discharged by the action of the feed portions of the cutter rolls onto the bed plate 3, with their edge 9 in contact with the straight edge or guiding wall 10 disposed at the far side of the bed plate 3.
The bed plate 3 for a portion of its length is preferably formed with a longitudinal slot 11 in which operates a feed chain 12 carrying at spaced intervals thereon angle members 13 serving as sheet propelling dogs. The endless chain at opposite ends of the slot 11 operates over sprockets 14 and 14', Figs. 1 and 2 of the drawings. The sprocket 14 is carried by a shaft 15 which has chain driving connection 16 with shaft 17 disposed parallel beneath the discharge end of bed plate 3.
Disposed parallel with shaft 17 and located above the same is a complemental shaft 19, the shafts 17 and 19 eachcarrying pairs of cooperating feed rolls and slitter knives 20 spaced in pairs throughout their length, the distance between the pairs of feed rolls and slitter knives on the respective shafts corresponding to the width it is desired to cut the body blanks from the sheet A as fed thereto by the endless chain 12. The shaft 19 is driven through a bevel gear connection 18 with the uppermost of the pair of shafts 5.
To properly align the blank A with reference to the rolls 20, I provide a shaft 21 disposed parallel with shafts 17 and 19 and positioned above the same, the ends of said shaft 21, like the ends of said shafts 17 and 19, being supported in journals in suitable brackets 22 secured to the side walls of the frame 1 adjacent the discharge end of the bed plate 3.
Secured to the shaft 21 at spaced points are the arms 22 weighted at their outer ends, as at 23, and each having on a depending portion a pivotally mounted finger 24, the ends of which are designed with relatively blunt portions 25 to project between adjacent pairs of feed and slitting rollers and to normally lie in contact with the free edge of the discharge end of bed plate 3.
Springs 26 connecting the fingers 24 and arms 22 afford means for normally maintaining the parts 22 and 24 in a position so that the end 25 of the finger 24, when pressure thereon is relieved, will lie in a position to contact with the edge of the discharge end of the bed plate 3. On the forward edge of the sheet A, as conveyed over the bed plate 3, arriving at the discharge end of the bed plate, the same encounters the blunt ends 25 of fingers 24, the action of which is to align the edge of the sheet A parallel with the discharge edge of the bed. Continued movement of the sheet A'by the endless chain 12 3 causes the forward edge of the plate to pass between the feeding portions 'ofthe feed and slitter rolls 20, and from this time on the sheet is fed andslit into body blanks by the rotation and action of the combined feed and slitting rollers 20. As the forward e of the sheet passes between the rolls, F1g. 5, springs 26 on the respective arms 22 yield, enabling the fingers to be displaced from within the path of the sheet.
The means for directing or guiding the body blanks or slit portions cut from the sheet A as discharged from the cutting and feed rollers 20 into classes or grades in accordance with their quality or perfection, is
, arranged and constructed in the present embodiment, as follows Connecting the lateral extensions 23' of brackets 22 and disposed substantially parallel with shafts 17 and 19 is a supporting shaft 27, the latter mounting at points between the spaced pairs of feed and slitter rolls 20 a supporting bracket 28 having a curved wall 29 and a laterally extending arm 30. The brackets 28 are in the present embodiment illustrated as being four in number, the same being free to rotate on shaft 27 and held from longitudinal movement thereon by the confining collars 31.
To the curved portion 29 of each bracket is secured a curved directing plate 32, the upper bevelled end of which, as in Fig. 2, normally lies at a point beneath the plane of the discharge end of the bed plate 3. The respective members 32 are downwardly and rearwardly curved with their discharge end 33 illustrated as lying beneath the discharge end of the bed plate3. To each lateral arm 30 is secured a core 34, and each core cooperates with an electro-magnet 35, the energizing of the respective magnets being controlled by manually operated contacts 36, preferably located at one edgeof the bed plate 2 within convenient reach of the operator.
The electric energy for operating the electro-magnets on the closing of their respective closing contacts may be supplied from any suitable source, a battery 37 connected with the magnets by suitable conductors 38 forming a simple wiring layout, is indicated.
Associated with each curved directing plate 32 is a pivoted latch member 39 of substantially T formation in side elevation, and each latch member is fulcrumed to pivot on a shaft 40 and is disposed with one end of its transverse portion 41 projecting through an opening 42 in the member 32 adjacent its discharge end.
The main portion of the latch 39 is weighted at 43 and the opposite end of its transverse portion 44 is adapted to ride on a bracket 45 and rest thereon until such time as displaced in a hereinafter described manner.
As previously explained, the curved directing plates 32 normally lie in the position indicated in Fig. 2 of the'drawings, with their upper end disposed so that the perfect body blanks D will'pass thereover and be received in their respective compartments B in a suitable receptacle.
On the operation of any of the contacts 36 the electro-magnet 35 connected therewith is energized, drawing the core 34 toward the same, which operation causes a movement of the bracket 28 on the shaft 27. This operation raises or elevates the upper or free end of the associated directing plate 32 to a position as in Fig. 3, in contact with a limiting finger 46 and causes the portion 44 of the latch 39 to rest on the bracket 45. The plate 32 is thus held in this position by the latch 39, even after the operated contact 36 is broken, and remains in such position, directing the discarded body blank D into the receptacle C.
. The body blank in its passage in contact with the undersurface of the plate 32 engages the portion 41 of the latch 39 and pivots the latch on its shaft 40, raising the weighted end 43 thereof, and by gravity the plate 32 swings on its axis about the shaft 27 to its normal position, as indicated in Fig. 2 of the drawings.
It will be understood that the operator employed for feeding the sheets to the bed plate 2 is enabled by closing any of the selected contacts 36, to cause the movement of the directing plates 32 from normal position, Fig. 2, to operated or set position, Fig. 3, and that the actuated plate or plates will remain in such position until such time as the body blank directed thereby into the receptacle C releases its associated plate from its passage thereover, thus the operator is enabled to set the plates 32 in accordance with his desire of classification of body blanks cut from the plate by the slitter mechanism.
This classification, at the will of the operator, is done as follows: Reverting to Fig. 1 it will be seen that the right hand side of feed table 2 adjacent the right hand longitudinal edge of the standard size tin plate A is graduated transversely or divided into four equal parts E, F, G and H, corresponding to the width of the four can body blanks which are ultimately to be cut from the standard size sheet in the second operation slitter, and also corresponding with the four contacts or switches 36 on slitter table 2. These graduations or divisions are for the guidance of the operator, who, when he detects a waster spot or imperfection, somewhere on the surface of the standard size sheet A, almost instantly locates such spot as belonging within the boundary of one of the areas E, F, G or H, and he accordingly depresses the first, second, third or fourth switch 36, with the result that the correct one of the directing or diverting plates 32 is raised to diverting position by means of its associated electromagnet and thus the defective'can bod blank is led to the proper discard receptacle C.
