DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) For a general understanding of the features of the disclosure, reference is made to the drawings. In the drawings, like reference numerals have been used throughout to identify identical elements.

(12) Referring now to FIG. 1, there is shown a system 10 for outputting printed shelf edge markers from a conventional unwinder 20 that roll feeds edge markers in continuous sheet form into a conventional perforator/slitter/cutter 30 that slits and cuts the continuous roll fed sheet of shelf retail edge markers into extended predetermined lengths of, e.g., 4 feet to 5 feet. Each predetermined sheet length is slit into four separate and individual strips and each individual strip is perforated into four different parallel sections to accommodate different in-store requirements. While this system feeds roll stock and cuts and perforates the stock, it does not include a system for accumulating and collating in-store shelf edge strips exiting the system.

(13) In accordance with the present disclosure, an accumulation and collation system 50 is disclosed in FIG. 1 that fits directly after the perforator/slitter/cutter 30 of the continuous roll feed system 10 that converts the edge markers roll into perforated and cut strips 52 shown in FIG. 4 and includes a series of angled baffles 60 that are identical and include bins 62, 64, 66 and 68 more clearly shown in FIG. 2 that accept and register the retail edge marker strips 52 from the perforator/slitter/cutter 30 and accumulates them as they exit perforator/slitter/cutter 30. Each angled baffle 60 is configured to allow retail edge marker strips exiting perforator/slitter/cutter 30 to cascade from the upstream angled baffle eliminating stub points and provides a downward slope to help the retail edge marker strips to be conveyed down the baffles. Bins 62, 64, 66 and 68 of angled baffles 60 are configured to allow the retail edge marker strips 52 to fall into place during the accumulation stage and then allow the retail edger marker strips 52 to be collated onto a final stack platform 79 after all of the retail edge marker strips 52 have been fed from perforator/slitter/cutter 30. At the end of the accumulation stage, a pusher 70 is moved orthogonally to the retail edge marker strips 52 to remove the retail edge marker strips from each bin onto the top of retail edge marker strips in bins of baffles 60 in succession to collate the retail edge marker strips onto final stack platform 79.

(14) An exemplary angled baffle 60 is shown in FIG. 2 that includes bin shelves equal in width with the exception of bin shelf 61 which is shorter or narrower. The shelves of bins 62, 64, 66 and 68 are critically positioned at an angle of approximately 20 in order to facilitate having the retail edge marker strips 52 separate and accumulate in the bins automatically by letting the retail edge markers strips drop and slide to the bottom of the bins. The bins edges also register longer retail edge marker strips. The narrower shelf 61 is critical in that it is necessary to accommodate different retail edge marker strip widths with the same angled shelve. When starting from the center line of the sheet of retail edge markers this keeps the different width retail edge marker strips in the last bin from overlapping the third bin which would then allow the edge of the last set of retail edge marker strips to get hung up on the tip of the angled shelf when they are being fed in from the upstream perforator/slitter/cutter 30.

(15) As shown in FIG. 3, each bin 64, 66 and 68 is stepped downward an increment, as well as staggered backward after bin 62 in order to prevent stubbing of retail edge marker strips on edges of a succeeding bin. In addition, the stepping and staggering of each bin with respect to the preceding one enhances registering long retail edge marker strips exiting perforator/slitter/cutter 30. Pusher 70 is arranged for pulling through openings between bins 60 towards platform 79 to unload retail edge marker strips from each bin and simultaneously convey the retail edge marker strips onto platform 79 into a collated stack. By doing the final collation in the cross process direction, it allows the operator, or system if automated, to collect the bin stacks of retail edge marker strips at the edge in the short move direction allowing for a fast collation process and reduces delay in the high speed continuous feed system which can stop and buffer for five seconds. Collating in the orthogonal direction from the feed direction, facilitates collation in that five second interval. Alternatively, while a five second buffer stop is preferred, the buffer could be more or less than five seconds and could stop until an operator action is performed rather than for a set time. Preferably, an optical mark is included on the edge trim of the last retail edge marker strip that is that is sensed to signal the system to stop and wait for the orthogonal pusher operation. The depth of the bins allow retail edge markers for an entire store to be accumulated prior to collating into a stack. The retail edge strip markers can also be accumulated and then pushed at predetermined break points if a store volume is too large of if the process can be improved by using set breakpoints.

(16) Bundles of retail edge marker strips 52 in FIG. 4 are shown in baffles 60 after exiting perforator/slitter/cutter 30 and settling into bins 62, 64, 66 and 68 ready for a single collation push onto compiling platform 79. Each bundle of retail edge marker strips 52 is made up of four retail edge marker strips separated by a perforation for ease in separating the retail edge marker strips for placement onto store shelf edges. In FIG. 5, a final collated bundle is formed by moving pusher 70 in a cross process direction across the angled baffles to stack the separate bundles into a single bundle and in in-store planogram order.

(17) A sensing arrangement is shown in FIG. 6 that shuts the system down if there is a jam or pileup of retail edge markers in baffles 60 and includes a dual use retro-reflective sensor 40 (Banner QS18) that directs a beam into mirror 41 mounted on a wall portion connected to compiling platform 79. The beam reflects off mirror 41 and against a reflector 42 that is mounted on upstanding support member 72 shown in FIG. 1 which assists in supporting pusher 70. The beam is then reflected back from reflector 42 to retro-reflective sensor 40. If for any reason the beam is broken, e.g., a jam or misaligned retail edge marker strips, the system 10 will be stopped. Dual use retro-reflective sensor 40 is also used to ensure that pusher 70 is back in the home position before giving a stacker ready signal.

(18) Another embodiment of the collator in accordance with the present disclosure is shown in FIGS. 7 and 8 and includes a baffle 80 that is positioned furthest from perforator/slitter 30 and accepts incoming retail edge marker strips conveyed in the direction of arrow 88. Baffle 80 includes a kicker bin 2 that that is the narrowest of the bins 1 through 4 and has an upstanding back portion that is tilted at an angle of 1 with respect to an upstanding portion of bin 3 of about 1 to bump the lead edge of incoming retail edge marker strips. This bump is critical in that it assists in separating the trail edge of a bumped retail edge marker strip from a retail edge marker strip entering bin 1.

(19) In FIG. 9, a stopper 90 is shown that is inserted using handle 92 into a portion of the baffle 60 farthest downstream from perforator/slitter 30 to change the length of retail edge marker strips 52. This facilitates system 10 outputting both 4 and 5 feet lengths of retail edge strip markers.

(20) It should be understood that an accumulation and collation system has been disclosed that collates retail edge markers which have been cut from a high speed continuous feed roll and fall directly into bins of a plurality of one or single piece stepped and angled baffles that drop downward and back from each other consecutively to provide both separation and registration of long media strips. The stepped and angled baffles are configured to allow the cut media to slide successively from the first of the plurality of stepped and angled baffles to the last angled baffle to eliminate stubbing points and provide a downward slope to ease the conveying of the media strips down the angled baffles. After all of the retail edge markers have settled into respective baffle bins a cross process collation system is actuated that includes a pusher that is used to orthogonally contact the retail edge markers and empty the first bin contents on top of the contents of the next bin and continue consecutively until all of the retail edge markers are pushed as one bundle onto a compiling or final collation platform for pick-up and distribution to a specific store identified on the edge markers. Cross process collation of the retail edge markers is performed after each store or job requirement is completed and the cross process collation is critical in that it facilitates compiling of the retail edge markers on the final collation platform in the shortest distance for reduced delay in feeding the retail edge markers to the accumulation and collation system.
