Definitions

• the present invention relates generally to improvements in the design and operation of an article containment area, storage area and system therefore, for use with an article handling apparatus, and is particularly useful for storing, containing and/or handling fragile articles, such as bags of potato chips, in a columnar/stacked manner.
• US Patent 5,240,139 represents a significant improvement in article handling devices. It describes the use of a negative air pressure lifter (i.e., article pickup or handling mechanism), which uses suction, i.e., a reduced or so-called "negative" air pressure created by a partial vacuum, for making a secure contact to an article to be retrieved by entering the open top of an article storage bin located in a refrigerated storage area of a vending machine.

• suction i.e., a reduced or so-called "negative" air pressure created by a partial vacuum
• robotic, and specifically suction-type lifting mechanisms are in common use in factory settings, where space limitations are generally relaxed, their use in tight confines, such as an article vending machine, has not gained wide acceptance. Due to the greater reliability and versatility of vending machines of the type which utilizes suction technology for grasping and moving selected articles, it would be desirable to develop new techniques and methods for the operation and control of such machines, as
• Article storage is provided in the forenoted US Patent 5,240,139 by arranging a plurality of vertically aligned storage compartments or bins within the freezer. Since the articles to be dispensed were frozen, the weight presented on the articles stored in a lower portion of the bin, by the stack of articles stored above, did not present the problem of product crushing. In some applications, however, the articles stored in the bins may be fragile (such as potato chips which are packaged in flexible bags), and means would then be necessary to prevent crushing of the articles stored near the bottom of the bin. Even if article storage in the dispenser used horizontal placement of the article storage bins, fragile articles could still be damaged during transportation of the storage bins from the warehouse or article manufacturer to the actual dispenser mechanism. It is desirable to make the article storage bins so that they have the most capacity possible, for example, by making the bins taller. However, the taller the storage bins, the more the above noted crushing problem is exacerbated.
• U.S. patent 6,082,578 entitled VENDING MACHINE FOR PACKAGED COMMODITIES discloses a vending machine wherein the articles to be dispensed are stored in vertical columns. In order to prevent the weight of the articles in the columns from crushing those articles near the bottom of the column, the vertical stack of products is divided into sections, with each section having its own article dispenser at the bottom thereof. Providing multiple dispenses to solve this "crush" problem is wasteful of the article storage volume, as well as requiring the use of many additional electromechanical components.
• AND OVEN COMPARTMENTS subdivides a vertically oriented article storage magazine into multiple vertically oriented sections. Each section includes a pair of opposed “retention levers” for engaging the bottom product in its section of the magazine.
• the “retention levers” are operated in a sequential manner in order to shift the stored products, one at the time of each vend, from a higher section to a lower section, until all of the products have been dispensed from the magazine.
• This technique would be somewhat undesirable for supporting articles comprising flexible bags, since the retention levers would have to extend quite far into the interior of the magazine in order to engage the bags in a supporting manner, and could therefore damage fragile products.
• U.S. patent 5,651,476 entitled MODULAR VENDING MACHINE and U.S. patent 3,175,669 entitled DEVICE FOR VENDING CYLINDRICAL OBJECTS are illustrative of the use of baffles along the inside portion of a vertical column of products, for staggering the distribution of the products in the vertical column, thereby preventing the weight of the products above from "bunching" or "jamming" a product feed mechanism located at the bottom of the column.
• the use of fixed position baffle elements are not sufficient to prevent damage to a column of fragile articles, such as a stack for bags of potato chips, and in fact the fixed position baffle elements themselves are likely to cause damage to the products.
• one of the general objects of the present invention is to provide new techniques and methods for the design, operation and control of article handling mechanisms.
• More specific objects of the present invention are to: 1) increase article storage capacity by increasing the height/length of a stack of articles, and manner so that forces which act upon the articles are prevented from causing damage, such forces comprising, for example the weight of the articles stored above or impact forces which result from shipping/transportation of the articles in a columnar form; 2) provide article storage bins which are designed so as to facilitate enforcement of the loading of articles in a FIFO manner;

• the storage area includes a plurality of axially aligned storage bins having an opening at a dispensing end thereof, wherein each storage bin includes at spaced positions along its length, opposed intrusions adapted to support at least the edges of articles stacked in the bin.
• the intrusions comprise opposed pairs of tabs which extend from the inside wall of the bin into its article storage interior. The tabs are flexibly biased within the bin so as to facilitate movement of the articles in a direction towards its dispensing end, and which at the same time hinder movement of the articles in a direction which is opposite to the dispensing direction.
• flexible biasing of the tabs is accomplished by attaching the tabs to the exterior the bin and having them extend into the interior of the bin via a hold in the bin wall.
• the thickness of the hole in the wall acts to create a support for the tabs which hinders movement of the tabs in a direction below the hole, while the whole as a height which is sufficient so as to allow the tabs to easily flex in a direction above the hole.
• the length of the tabs are predetermined so that the space between their opposed free ends is sufficient to allow the article gripping mechanism to freely pass therethrough, and the flexible biasing of the tabs is not strong enough to dislodge an article from the article gripping mechanism as a result of contact between the tabs and the article during removal of the article from the storage bin.
• the article storage bins may be segmented and pre- f ⁇ lled with articles at a warehouse, or even at the facility of the article manufacturer,
• the segments may comprise at least a portion of a shipping container from the manufacturer or warehouse for use in refilling/filling the article dispenser.
• the use of bin segments preloaded with articles enable the operator of the dispensing apparatus to realize significant savings in time and labor during the restocking process, due to not having to take the previously un-sold articles from the storage bins back to the warehouse.
• the storage bins themselves may have a full height which is appropriate for the storage area, and sleeves comprising prepackaged groups of articles can be inserted into the storage bins for refilling/filling through an opening at or near a bottom portion thereof.

• Article ID device 254 is mounted within cabinet 12 at a relatively fixed location, the mounting being such that some controlled movement in the orientation of article ID device 254 may be facilitated, in order to help ensure a good "view" of the article being transported, and a high confidence of the transported articles being identified.
• ID device 254 One way to provide such controlled movement for ID device 254 would be to mount it on a piezoelectric substrate, and control system 400 could provide a voltage to the substrate so as to shift the "view" of ID device 254. It is noted that by using an appropriately positioned article ID device 254, only a single article ID device 254 is needed. This is particularly useful for a robotic type dispenser, since the robotic apparatus can controllably position, and re-position if necessary, the article in the vicinity of the article ID device 254, thereby helping ensure a reliable ID of the article.

• Accurate control of energization of blower motor 226 is particularly advantageous in the event that the inside of the cabinet, or a portion thereof, is refrigerated, since accurate control would decrease the amount of refrigerated air being displaced by blower motor 226.
• the microprocessor 402 will energize blower motor 226 as the pickup head 224 approaches the desired article, and in fact only when it is in the immediate proximity of the desired article (and not earlier), due to control system 400 maintaining updated information about the height of the stack of articles in each bin 216. The height is assumed to be at a predefined level upon article refilling/filling of the vending machine 10 by the operator.
• Control system 400 may confirm the assumed height by moving the pickup head 224 at a reduced speed towards an article at the top of a bin 216 on the first retrieval attempt after the storage area has been refilled, and then compare the assumed height to the actual height.
• Memory 404 can be pre-programmed with specific article heights in advance, or the heights can be learned by control system 400 by comparison of prior vend heights in each bin. Once the height of the top article is known, control system 400 will be able to always know the height of the next "top" article in that bin. Subsequently, control system 400 may cause the pickup head 224 to approach the articles in that storage area at a higher speed, and only slow down when in the immediate proximity of the next "top” article in that bin. The technique to slow down upon the pickup head 224 approaching the next article also helps ensure that the stored articles will not be damaged by the pickup head 224.
