A packing method and apparatus are disclosed utilizing carrier stock comprising an elongated multi-leaf flexible strip assembly adapted, such as by a series of perforations therein, to be machine fed lengthwise in positive manner and the leaves of which spread apart progressively as they approach a packing station. There the cut films and prints are packed in the strip assembly by transverse insertion into the open spaces between the leaves in such timed relation with advancement of the strip assembly as to space the groups of interrelated items respectively in successive carrier-length sections of the strip assembly. Then the packed individual carrier-length sections are severed from the stock body for subsequent processing. In the preferred embodiment the carrier stock leaves, of material protective to the films and prints, are transversely scored and thereby weakened at carrier-length intervals along their lengths so as to permit severing the carrier-length sections by tearing. The face leaf is transparent so as to permit markings to be seen through it, and is of lesser width than an underlying leaf such that the latters projecting edge may serve as a marking tab.
11 Claims, 14 Drawing Figures PATENIE m 2 2 I975 SHEET 2 [IF Ar/rn BY PROCESSORS METHOD AND APPARATUS FOR PACKING PHOTOGRAPHS BACKGROUND This application is a continuation-in-part of Ser. No. 26,723 filed Apr. 8, 1970, entitled Package for Sheet Material by Leonard H. Tall and Arlen J. Erickson (now abandoned). v
In photographic film processing laboratories which handle a large volume of exposed films, developed negatives and prints, the film strips received from customers are generally processed in continuous strip form, one customers film being spliced onto that of another and the entire strip fed continuously through the development machine and thereafter through a printer with an emulsion paper strip. Finally the continuous film negative and print paper strips are severed into individual prints and negatives and these segregated and grouped by individual customer orders for packaging. The assembled prints and negatives with any other items to be packaged with them in total are then inserted by hand into a delivery envelope.
The above-described procedure in a competitive photographic processing laboratory represents a relatively large item of expense. At the low profit margin involved it is difficult to pay wages which will attract reliable and steady employees. Also the procedure is further complicated for the processor because it is necessary to provide considerable working area for the number of operators and the space they require in order to keep up with the production rate capability of automatic film and print processing apparatus now in use. Moreover, if the operators are unskilled or careless, expensive mistakes are readily possible in the mixing up of prints and negatives of different customer orders. If the mistakes are fortunately caught in time, the loss is only directly in terms of extra delay and wages, but of course, if such an error is not caught before the work product is released to customers, possible claims of damages may result, as well as loss of business good will.
A broad object of this invention is to overcome the above and related problems.
A further object of this invention is to provide an improved technique, including a mechanical packing technique and related carrier means which is designed essentially to facilitate machine correlation, packing and subsequent handling of such items as interrelated groups of films and prints in a photographic processing laboratory. A related object is to provide interim protection and reliable retention of the related items together as a group. Thus in the case of photographic films and prints of a laboratory customer, the invention protects the delicate emulsion surfaces against marking or abrasion and prevents physical mix-ups between the prints and negatives of other customers by fumbling or careless handling throughout subsequent procedures such as quality control inspections, pricing, and finally insertion into customer delivery envelopes. Moreover, the novel carrier means utilized conveniently remains as a retaining and separating carrier for the items adding an important degree of protection to the items even in the delivery envelope.
A further object hereof is to devise an inexpensive and rapid technique for protectively packing and separating individual customer orders of associated prints and negatives or similar items.
Still another object of the invention is to devise an improved carrier device and carrier device stock which can be fed into and through a packing machine to receive individual customer orders of photographic prints and negatives. A related object is to provide such a stock, carrier-length sections of which can be readily severed in the machine as each successive section receives its assigned group of prints and negatives. Further the improved carrier is so designed as to facilitate identifying inspection of items packed therein without removing them from the carrier.
A further object of the invention is to devise a novel carrier stock of the general character indicated which is adapted to be machine fed in indexed timed relation to machine feed of the cut film strips and negatives so as to reliably correlate the associated negatives and strips for insertion into the same carrier and to assure proper location of the packed items between the end margins of the carrier-length sections of stock before severance.
BRIEF DESCRIPTION In accordance with the invention the packing carriers which serve as collecting and interim retainers for the;
cut films and prints are severed as sections of carrierstock which comprises an elongated multi-leaf flexible strip assembly made up of mutually superimposed. leaves of paper-like strip material joined together substantially continuously along a common first-longitudinal edge and freely separable from'each other substantially continuously along. their opposite second longitudinal edge. The leaves of the strip assembly have resistance to tearing in a longitudinal direction which is substantially uniform across a major portion of the width thereof extending from the first edge towards the second edge of the strips and in the preferred instance the strip assembly is transversely scored and thereby weakened at intervals along its length so as to permit severing individual carrier-length sections therefrom by tearing. In order to permit progressive separation of the leaves of the carrier assembly for machine packing with negatives and prints as the strip assembly approaches the loading station of the packing machine, it is preferred that the transverse scoring of the strips which weakens the assembly for tearing be terminated short of the second edge thereof so as to maintain greater strength against such tearing adjacent the latter edge when the strips are being spread apart and subjected to any stresses in the packing operation. Once the negatives and prints are inserted into the inter-leaf spaces of the carrier strip, the negatives being inserted in a pocket space adjacent that occupied by the related prints of the same customer order, and at a location intermediate successive score lines in the strip, the sectional length of. carrier which contains the negatives andprints is then torn off for subsequent inspection or other handling and for eventual insertion into a delivery envelope.
Preferably an outside leaf of the carrier is substantially transparent so as to permit reading through it markings on an item packed behind it, and the second edge of the leaf behind the transparent leaf projects beyond the second edge of the transparent leaf so as to provide space for labeling if desired on the projecting edge. In the preferred embodiment the carrier stock strip assembly has a series of perforations formed in and along the joined edge thereof which are machine engageable so as to permit feeding the stock positively and thereby enabling it to be positioned correctly for each action cycle of the packing mechanism which inserts the films and negatives.

DESCRIPTION BY REFERENCE TO DRAWINGS As shown, the elongated carrier stock strip assembly 100 of this invention may be bulk stored compactly for feed purposes in an accordion fold configuration (FIG. 1) and thus retained in a bin 104, or it may be stored in a rolled configuration 130 upon a shaft (FIG. 7). In FIGS. 1 through 5, the illustrated carrier stock strip 100 comprises an elongated multi-leaf flexible strip assembly including mutually superimposed leaves of paper-like material such as cellulosic pulp paper or, if desired, any of various other natural or synthetic materials which may be made or are inherently suitable to protectively engage and cover photographic emulsion surfaces without marking or marring them while in sliding contact under pressure. In this instance four leaves are shown, designated respectively 52, 54, 56 and 58. The successive leaves are interjoined substantially continuously along a common first longitudinal edge 62 and are freely separable from each other substantially continuously along their opposite second longitudinal edge as shown in FIGS. 3 and 4 for packing of items bev hind the leaves. The separable edges of the respective leaves are designated 60, 68, 74 and 80. Also the leaves of the strip assembly have a resistance to tearing in a longitudinal direction which resistance is substantially uniform across a major portion of the width of the strip assembly extending uninterruptedly from the interjoined edge 62 toward the opposite edge of the strip assembly, so that as the leaves held at edge 62 by feed mechanism are being progressively spread apart and otherwise stressed in the machine loading process, or later severed in carrier-length sections 50 from the stock, the leaves will remain intact and together. In FIG. 3 stationary elements 116 comprising parts of a packing machine are interposed between adjacent leaves along the path of feed of the strip assembly so as to progressively open up the leaves for eventual reception of the prints and negatives.
The strip assembly depicted in FIG. 1 is transversely scored or perforated and thereby weakened along tear lines 102 at intervals spaced along its length so as to permit severing individual carrier-length sections 50 thereby by tearing, as at the right-hand side of FIG. 1. Such severance of the successive carrier-length sections occurs after each is loaded with its group of negatives and prints for the customer.
In FIG. 4 a severed carrier 50 is depicted. In this embodiment an intervaled series of holes 86 is formed in and along the interjoined edge 62 of the strip assembly. These holes are engageable by pins 108 (FIG. 1). These project from the outer face of an endless feed chain 106 encircling spaced sprockets 110- and 112. One of these is intended to be driven in any suitable or known manner so as to properly feed and position successive sections of the stock 100 at a loading station when the loading mechanism is to cycle. The loading station in FIG. 1 has two sections 118 and 124 spaced respectively along the length of feed of the strip assembly. At station section 118 a suitable mechanism 120, the details of which are not here important, deposits negatives 122 into a pocket between leaves of strip assembly 100. At station section 124 a mechanism 126 deposits the related prints 128 of the same customers order adjacent the negatives 122, meanwhile the feed 1061 12 having advanced the strip assembly by the necessary distance to achieve such registry. As depicted, the negative loader inserts the negatives 122 between the leaves 56 and 58 at a location along the strip assembly 100 intermediate successive score lines 102 which define a single carrier-length section of the assembly. The mechanism 126 inserts the associated customer order prints 128 between two other leaves such as the leaves 54 and 56 of the same carrier-length section 50. Into the remaining or third pocket of the illustrated carrier (FIG. 4), such as that defined between the leaves 52 and 54 may be deposited, at either station section 118 or 120 or at a third (not shown), any special items such as film ends, overexposed or underexposed sections of film, notices or other sheet items (such as in FIG. 10). Thereafter, that is with the last carrier-length section 50 loaded, it is torn off either manually or by machine at a score line 102. It may then undergo any further procedures including ultimate insertion in an appropriately identified customer order envelope E (FIG. 14).
It will be appreciated that the illustration of FIGS. 1 and 3 is simplified and schematic. Thus, whereas the leaf spreader elements 116 are shown as simple plates it will be recognized that these are intended to illustrate a function and that any of various spreader configurations may be employed to open up the leaves of the advancing strip assembly as its sections approach and reach the loading station of the packing machine. Also it will be self-evident that details of the loading means may vary. In FIG. 1, for example, the loading station comprises successive sections 118 and 124. FIG. 11 portrays successively located loader guides 200, 204 and 208, such as in a two-or three-section loading station machine. FIG. illustrates the case of FIG. 7, however, wherein th prints and negatives are deposited into the same carrier-length section of the strip as by means of loading chutes depicted as 184, 186and 188, respectively, with the carrier stock 100 remaining in the same feed position as all pockets are being loaded. Alternatively, of course, any separate items suchas 190 in FIG. 10 or 210 in FIG. 11 may be inserted by hand into a carrier pocket. The chutes may be fixed as spreaders between leaves.
In the operation of the process and machine depicted in FIG. 1, it will be recognized that any suitable controls and drive mechanisms may be incorportated by which to operate the loading mechanisms 120 and 126 in timed relationship with the advancement of the carrier strip assembly 100. Because the pins 108 positively engage in the feed apertures 86 in the bound edge 62 of the carrier strip assembly slippage is avoided and, either with the strip assembly in motion or with it temporarily. arrested at each point of discharge from the loading mechanisms 120 and 126, the negatives and prints are deposited in the spaces between successive score lines 102 in such a manner that the prints and negatives of a given customer order will be packaged in the same carrier-length section 50 subsequently to be torn or detached from the succeeding strip. During detachment of the endmost loaded carrier 50 the feed means pins 108 engaged in the holes 86 of the following body of strip 100 firmly hold the latter against shifting when the tearing occurs. For example, operation of the feed mechanisms 120 and 126 may be made intermittent so as to advance the strip 100 by increments, and with the pause that marks completion of each step of feed an automatic control or a human operator may actuate one or both loading mechanisms 120 and 126. Alternatively the method may be practiced with the drive motion a continuous one and the loaders operable at correctly controlled intervals to insert their loads into the proper sections 50 of strip 100.
In the modification shown in FIG. 5 instead of holes 86 formed in the bound edge portion of the carrier strip assembly, notches 90 are formed in the very edge thereof and may be used as a means to provide a positive indexing or positioning means for driving of the strip assembly positively. Mechanism for engaging the notches 90 is not illustrated but may be of any suitable or known type which is equivalent to that representing the chain supported drive pins 108' depicted in FIG. 1. If sufficiently reliable and positive, frictional surfacing of the stock to enable feeding and positioning the stock positively may be employed, or the stock may be perforated by sharpened pins on a feed wheel or the like in the act of feeding it to a similar end. The important re quirement is that of positioning each successive carrierlength section of stock in correct loading position for each loading sequence of the machine.
The packing machine and process depicted in FIG. 7 is assumed to be for use in feeding and packing a strip assembly such as that shown in FIG. 6 stored in a roll at 130. The strip assembly 121 in this instance comprises two or more leaves of flexible paper-like material interjoined at a first longitudinal edge 125 and having respectively severable opposite edges 123. Machine feed apertures 127 are located in series along the edge 125 as in the previously described embodiment of the strip assembly, and in this case transverse score lines to weaken the strip assembly leaves are omitted. Instead severance of successive carrier-length sections from the carrier strip assembly is accomplished by means of a shear 146, 150.
In addition optically detectable indicia marks 129 located at carrier-length intervals along the strip assembly are sensed by a photocell device 142 and associated light source 144 using known or suitable circuit techniques in order to control operation of the shear, also of the loading mechanism 132 by which negatives 138 and/or prints 131 are inserted between the separated leaves 134 and 136 of the strip assembly. Illustration of the feed mechanism for advancing the strip assembly is omitted from FIG. 7 as are the means by which the leaves are separated.
In the operation of the mechanism shown schematically in FIG. 7, it is assumed that suitable feed mechanism such as that shown in FIG. 1 is operated to advance the strip assembly from the roll past the loading mechanism 132 and thereafter past the photocell sensor 142 and the cutter mechanism 146. The cutter 146 is so positioned in relation to the photocell and the latter in relation to the loading mechanism 132 that each time the strip assembly reaches a certain point of advance the photocell senses the presence of an indicia mark 129 causing actuation of the cutter mechanism 146 and of the loading mechanism 132. The strip assembly is then positioned such that the cutter 146 correctly severs a previously loaded carrier-length section 153 of the strip assembly. The section drops into a receiving bin 152 at the same instant the loader 132 inserts prints and/or negatives into the carrier strip.
In FIG. 8 a carrier or package 20 is depicted having a first leaf 22 and a second leaf 24 mutually superimposed in the leaf 22. The leaves are joined together along a common edge 28, 36 and are separable from each other along respectively opposite edges 26 and 34. The intervening side edges 30 and 32 of leaf 22 and side edges 38 and 40 of leaf 24 are also separable for reception of sheet material between the leaves. The joined edge 28 has a series of drive pin apertures 42 for machine engagement in feeding and packing of the strip assembly from which the carrier has been severed in the described process.
In the embodiment shown in FIG. 9 the strip assembly comprises an elongated bound edge 164 joining the leaves together and an opposite edge 162 at which the leaves are separable from each other. The individual carrier length sections of the strip assembly are defined by transverse score lines 168 spaced at intervals along the length thereof and in this instance the joining together of the strip assembly along the first longitudinal edge 164 is accomplished by the use of an adhesive interlayer 166. The adhesive extends upwardly along the side edges of the individual carrier length sections in the narrow regions 174 by materially less than the distance from the bound edge 164 toward the separable or free edges 162 of the multi-leaf assembly so as not to interfere substantially with spreading of the leaves during loading of the carrier. Thus the leaves are still freely separable at the edge 162 and for a dis tance across the width of the strip assembly toward the bound edge 164. These bounded regions 172 partially close off the ends of the carriers 170 so as to form a shallow pocket in each.
In the embodiment of FIGS. 12 and 13 the presently preferred form of the carrier strip assembly appears, featuring in this instance four mutually superimposed leaves of paper-like strip material respectively designated 300, 302, 304 and 306, these being bound together along a common longitudinal edge at 308 by interposed adhesive deposits 310. Machine drive perforations 312 extend in spaced series relationship along the bound edge of the assembly as in previous embodiments and in this instance at least one of the front or face sheets, such as 306, is formed of a relatively transparent material such as a thin tissue paper through which markings are visable, such as identification numbers or initials which may be placed on items stored in the space between the sheet 306 and the sheet 304. Also in this instance leaf 306 is narrower than leaf 304 (or a succeeding leaf) so that the free edge 306a of sheet 306 is located short of the free edge 304a of sheet 304. The edge 304a then provides a projecting marginal tab 304b available for labeling or similar usage.
Also in this preferred embodiment the transverse score line 306c which weakens the face leaf 306 for tearing transversely, and the similar score line 3040 applied to the next sheet 304 (and similarly to the sheets beyond it) start at the bound edges of the assembled leaves and terminate short of their respective free edges 306a and 304a. Therefore the leaves are strengthened against such tearing prematurely at those edges where and while stress in the strip assembly during loading is greatest, namely at the spread-apart edges of the carrier assembly during loading thereof. Also in FIG. 12 it will be seen that photoelectrically detectable markings 314 applied to the carrier strip assembly at interval locations along the length thereof may be used to control timing of the loading sequence as in previous embodiments.
