B. Description of Related Art
Product packaging can be a labor intensive endeavor, particularly when the product to be packaged must first be separated from a bulk article that is purchased from a farm or other locality. In order to separate a product to be packaged from the bulk article a grading and sorting system is typically used to break apart the bulk article into smaller pieces, separate the pieces from each other according to size and package the variously sized articles within bags. Such grading and sorting systems employ the use of hoppers, conveyors and vibratory motion to grade and sort the bulk article. In certain industries, however, it may be desirable to track the bulk article throughout the grading and sorting system to account for the total amount of bulk product that is processed including any remnants from the bulk article that are not processed. It may also be desirable to grade and sort the bulk article into pieces which are small enough to automatically fit within an opening of a bag without the need for human manipulation of the graded and sorted product. Moreover, it may also be desirable to provide a grading and sorting system which is run by software which directs a specific or pre-set amount of graded and sorted product to be placed within a package and which times the operation of the various components of the grading and sorting system so that they are synchronized. Such synchronization may allow for a pre-set amount of graded and sorted product to be packaged within a bag which has already been labeled with data related to the amount of graded and sorted product. The present disclosure provides various embodiments of a system and method which may achieve these results.

The method includes the steps of: receiving a bulk article to be inventoried and measuring the weight of the bulk article on a receiving load cell; inserting the bulk article within a hopper for separating the bulk article into smaller pieces; allowing the bulk article to pass through an aperture at a bottom portion of the hopper to fall on a first tray positioned under the hopper, wherein the first tray includes a plurality of indentations which form a plurality of grooves within the first tray; applying vibratory forces to the first tray allowing the bulk article to be separated along the grooves within the first tray into graded and sorted product, wherein the vibratory forces on the first tray cause the graded and sorted product to travel towards a second tray; allowing the graded and sorted product to fall onto a second tray positioned below the first tray, wherein the second tray includes a plurality of indentations which form a plurality of grooves within the tray for further separation and alignment of the graded and sorted product, applying vibratory forces to the second tray allowing the graded and sorted article to be further separated along the grooves within the second tray and wherein the vibratory forces on the second tray cause the graded and sorted product to travel towards a third tray; allowing the graded and sorted product to fall onto a third tray positioned below the second tray, wherein the third tray includes a plurality of variously sized channels; applying vibratory forces to the third tray allowing the graded and sorted product having a size within the dimensions of a particular channel to enter into the channel and fall towards a load cell positioned below the channel, wherein at least two load cells are positioned within a carousel below the third tray and a bag within the load cells receives graded and sorted product having a size which permits entry within an opening of the bag without causing bridging of the channel; recording the weight of the graded and sorted product within the bag in the load cell through use of a sensor within the load cell; allowing the carousel to rotate the load cell when it is filled to the appropriate pre-set weight and position a subsequent load cell under the channel; removing the bag filled with graded and sorted product from the load cell on the carousel thereby rendering the load cell empty; using a label machine for applying data related to the inventoried bulk article and the graded and sorted product onto a label and applying the label to a bag prior to disposal of the bag by the bagger machine onto the empty load cell on the carousel, wherein inventory data is encoded on the label through one of the following: an identification number, a bar code and a quick release code; and rotating the carousel so that the load cell without a bag is positioned adjacent a dump window on a bagger machine and allowing the bagger machine to dispose a bag within the empty load cell on the carousel prior to disposal of the product from the channels of the third trays in the load cell; and using a computer programmed to execute the steps of: recording and saving data related the weight of the bulk article as it is measured in the receiver load cell within the internal memory of a computer, referred to as the “weight-in”; recording and saving data related to the weight of the graded and sorted product as is it measured in all of the load cells within the carousel within the internal memory of a computer, referred to as the “weight-out”; calibrating the automatic grading, sorting and packaging system so that the “weight in” of the bulk article is equal to the total “weight out” of the graded and sorted product contained within the bags of the respective load cells; instructing the label machine to print a label including the “weight-in” of the bulk product and the “weight-out” of the graded and sorted product prior to insertion of the graded and sorted product into the bag.
Provided is a system for automatic grading, sorting and packaging articles. Also provided is an apparatus and method for automatically, grading, sorting and packaging articles. The automatic grading, sorting and packaging system provides an effective way to grade, sort and package articles separated or originating from a bulk stock while at the same time tracking the articles from the point of entry into the system up to the point of packaging. The automatic grading, sorting and packaging system also effectively and efficiently grades and sorts the articles to a size sufficient to pass through a chute into a package without causing bridging at the opening of the chute.
In certain embodiments, the system is a two part system comprising a grade and sort system and a feed and packaging system. The grade and sort system is capable of receiving a bulk article, grading that article into different sizes and lengths and sorting the graded article according to size and length. Articles which are graded are transported through a feed system through the use of micro-vibratory forces for placement into specifically designated bags for packaging. These micro-vibratory forces are applied by vibratory machines to the various trays of the system. The micro-vibratory forces cause the bulk article to separate into differently sized pieces and position themselves along various grooves or channels within the trays. The micro-vibratory forces also cause the article pieces to align and elongate themselves so that article pieces of specific lengths may pass through specifically sized channels within a tray for packaging within a particular bag. The channels themselves further assist in aligning and creating elongation of the product as the product cascades down or over different levels within the system. The bags may be housed within the load cells of a carousel unit which rotates around the tray containing the channels. As the load cell is positioned under or aligned with a particular channel, the graded and sorted article may be caused to pass through the channel and a chute into the appropriate bag. In certain embodiments, the specific dimensions (e.g., the width) of the channels may be designed in conjunction with the size of the opening of the bag. This is to ensure that only graded and sorted products having appropriately sized width and girth for passage through the opening of a bag are capable of passing through the channels. This design prevents bridging of the graded and sorted product between the chute and the bag. For example, in certain embodiments, the channels may have a width of 1.34 inches to ensure that only graded and sorted products within that size fit within the channels and pass through the opening of the bag. If products having a width larger than 1.34 inches were permitted to pass through the channels, bridging of the product between the chute and the bag would occur, thereby blocking passage of products through the channel into the bag.
In further embodiments, the micro-vibratory forces may be applied by vibratory machines which are integrated with the second tray. In such embodiments, the second tray may be stationary and have a 5 degree angle relative to its horizontal axis. This allows the incorporation of a vibratory conveyer system with the vibratory sorting system.
The disclosed system also includes a bag labeling apparatus and process and software for entering and tracking data related to a particular bulk article from the moment it is received and inventoried to the moment it is graded, sorted and packaged. The overall process begins when the bulk article is received by the purchaser. The bulk article is weighed by a receiving load cell within the system. This weight is recorded within the software and is characterized as the “weight in” of the bulk article. Data related to the origins of the bulk article such as the farm where it was purchased from, the type and strain of bulk article purchased, time and date of the order, shipping data related to the order and the time and date of receipt of the order are also entered into the software. This data is transmitted by the software to a label machine which uses the data to create a label containing at least some of this data for a bag that is to receive the graded and sorted product. Thus, the disclosed system allows for the creation of labels for bags prior to the packaging of the bags with graded and sorted product.
The process of receiving, weighing and recording data related to the bulk article may be referred to as a bulk density inventory control system. After recording data related to the bulk article, the bulk article may be subsequently fed or processed through the Automatic Grading, Sorting and Packaging System or it may be stored in inventory for later processing. When an order for a certain amount and type of product is received, the bulk density inventory control system allows the user to retrieve the bulk article from inventory and place it through the grade and sort system and the feed and packaging system of the Automatic Grading, Sorting and Packaging System. The sort and grade system and the feed system break down the bulk article into an appropriately sized product for a particular bag opening and align the product for packaging within the bag. The broken down product passes through various channels within the feed system, exits the feed system through a chute and falls into a bag housed within a load cell on a carousel.
In certain embodiments, the grade and sort and feed system include three trays or vibratory conveyors. The first tray may, in certain embodiments, comprise a flat deck having a plurality of indentations which form various grooves within the tray. The second tray may, in certain embodiments, be positioned below the first tray and comprise at least one v-tray also having a plurality of indentations which form various grooves within the tray. The v-tray may be angled downward from a pivot point so that the interior end of the v-tray faces a third tray which is positioned below the v-tray. The outer end of the v-tray may include a pivot allowing the v-tray to be angled downward towards the third tray. The third tray includes variously sized channels allowing graded and sorted product of specific sizes to pass through into a bag for packaging. In certain embodiments, the channels within the third tray may comprise v-channels which are angled downward from a first end of the third tray to a second end of the third tray. This angled decline of the channels allows graded and sorted product to pass through the channels, through a chute and into a bag for packaging. In certain embodiments the first tray vibrates at a slower rate than the second and third trays. This allows for the initial breaking apart of the bulk article. In further embodiments, the second tray vibrates at a speed that is twice that of the third tray containing the channels. This allows for further separation of the product into smaller pieces of various individual lengths as well as alignment of the graded and sorted product before it enters the channels in the third tray.
In certain embodiments, the second tray and third tray may be integrated within a sort table. In further embodiments, interchangeable screens may be located at the beginning of the sort table upstream from the second tray in such a position that product received from the first tray must pass through these screens as it enters the second tray. This allows for the passage of particulates that are smaller than the screen size onto the second tray. After passing through the screens, product is then moved through the sorting tray separation process performed by the second and third trays.
As mentioned above, the bulk article is graded and sorted into a product which is packaged within bags positioned within load cells of a carousel unit. In certain embodiments, carousel operates by positioning the load cells under different sized channels of a tray. The load cells may include a female receptacle for catching product from the channels. In certain embodiments, a bag is positioned within a female receptacle of a particular load cell for receiving product from a particular channel. A chute is typically employed to transfer product from a channel to a bag within a particular load cell. Before a bag can receive product from a particular channel, the bag must be positioned within the load cell. In certain embodiments, this is accomplished through use of a bagger machine. Therefore, in certain embodiments, the carousel is designed to receive timed delivery of bags from the bagger machine. This may be accomplished through the use of software which times the delivery of the bags from the bagger machine to the load cells on the carousel. In certain embodiments, the labeling device operates by creating labels for up to three bags ahead from the current label being applied to a bag within the system.
Before the bagger machine inserts a bag within a particular load cell, it may be desirable to apply a label to a particular bag. Accordingly, in certain embodiments, the bagger machine works in conjunction with a label machine to apply a printed label onto a bag before the bag is inserted within a particular load cell. Through the use of software in communication with the label machine, the label applied to the bag may contain data related to “weight in” of the bulk article and the weight of the product to be inserted within the particular bag referred to as the “weight out” of the graded and sorted product. As mentioned above, in certain embodiments, the grading and sorting system may include four different sized channels for grading and sorting different sized product. In such embodiments, the grading and sorting system may also include four different load cells within the carousel for receiving graded and sorted product from these four channels. These four load cells may further contain weighing sensors or devices to register and record the weight of the product that is inserted within the bags contained within the respective load cells. In such embodiments, the system is calibrated so that the “weight in” of the bulk article is equal to the “weight out” of the product contained in the respective bags of the four load cells. Thus, in certain embodiments, the system may be described as being calibrated to zero, meaning that the “weight-in” of the bulk article is equal to the “weight out” of the graded and sorted product as measured by the load cells. Accordingly, the disclosed software not only tracks the weight of the product as it enters and exits the system to ensure that all product is accounted for and that no product is lost through the grading and sorting process but it also controls the separation, distribution and packaging of graded and sorted product into the bags on the load cells of the carousel.
The grading, sorting and packaging system through use of the software tracking and accountability system ensures that only the specific weight listed on the bag label is inserted within the respective bag that is to be packaged. This may be accomplished through the use of sensors or a weighing device within the load cell. When a particular weight is reached, an instruction may be sent to software controlling the grading and sorting apparatus to stop flow of product through a particular channel and allow the bag within the load cell to proceed to the final packaging step.
In certain embodiments, the channels within the grading and sorting system may be used to sort product into four different categories. For example, the product may be sorted into four different categories defined by their length such as one inch, two inches, three inches and four inches. This may be accomplished through the use of appropriately sized channels (e.g., one inch, two inches, three inches and four inches).

In an alternative embodiment illustrated within
An alternative embodiment of the carousel (70) is illustrated within
In certain embodiments, the carousel may have a secondary dump sequence designed for hand packaging rejected product or for hand packaging product after the grading and sorting process has halted. In such embodiments, the carousel can be considered to comprise four stages with the first stage consisting of receiving the weighted product and the fourth stage consisting of the weighted product being dumped into the alignment shoot to the packaging machine. In such embodiments, the third stage or position of the carousel may be used to feed a hand packaged process or another type of packaging process.
In certain embodiments, the disclosed Automatic Grading, Sorting and Packaging System may be utilized in conjunction with tracking software run on a computer. The computer includes a processing system capable of executing various instructions or steps received from the software. The software may be used to record data related to the bulk material product from entry within the system until discharge and packing of the final graded and sorted product. Upon receiving inventory at a load station, a user of the software within the system may enter data related to the farm or location of purchase of the bulk material product, the weight of the product, the date and time of receipt of the bulk material product, the date and time of purchase of the bulk material product, the order number of the bulk material product, the specific type or strain of bulk material product, an employee identification number of the user entering the data and performing the grading and sorting, the purchase code of the bulk material product, comments, the brand name of the bulk material product purchase, the estimated time to market of the bulk material product, the price paid per pound or unit of the bulk material product, etc. The received bulk material product may then be subject to quality control and grade where it may be further scaled. The software may instruct the computer processor to save this inventory data within the internal memory of the computer. Subsequently, the software may instruct the computer processor to upload this inventory data to be posted on a retailer's website. The bulk material product may then be sorted into various grade sizes. Information related to grade size, load identification and grade weight as well as other information is entered into the software. The software may instruct the computer processor to save this data within the internal memory of the computer. Subsequently, the software may instruct the computer processor to upload data related to the various grades for posting on a retailer's website as processed inventory. This processed inventory data includes the brand name of the product, the estimated time to market, the estimated volume of product in stock, the estimated price per unit of product and order information of the product. After the product is sorted into various grades it is further scaled, processed through the feeder system, packaged and labeled. The software instructs the computer processor to track the product as it is fed through the feeder system, packaged and labeled into a particular product form (e.g., a cigarette or an edible), store this data within the internal memory of the computer and upload the data related to available inventory for purchase for posting on the retailer's website. Such information includes the brand name of the product, the volume of product available, the price per unit of product and order information. The package may include a label having a bar code or quick release (QR) code which may contain product information embedded therein. This code may be scanned by a scanner within the system. The software may receive and decode the scanned information and instruct the computer processor to save this data within the internal memory of the computer. Subsequently, the software may instruct the computer processor to upload this data to be posted on a retailer's website. Thus, the software permits the uploading of product purchasing information on the retailer's website. Customers may access the retailer's website for offers to purchase various products. In addition farms selling bulk material product may access the website to view price offers for purchasing bulk material products by the retailer or distributor. After an order is placed by the customer or an offer accepted by a farm, the software may set instructions in place through the computer processor to arrange for transportation of product and set a delivery time and place.
In other embodiments, specific identification numbers or codes of the various variables related to any type of inventory data (including inventory data described above) may be generated and linked with the actual weight data assigned to a particular load cell within the system (this process may be applied to all load cells within the system). The identification numbers or codes may then be processed through software and printed on a corresponding label assigned to the specific package being produced. This process may be repeated in each of the four zones of data generation which include receiving product, grading and sorting product, packaging product and shipping product.
The Automatic Grading, Sorting and Packaging System may be used to grade, sort and package any food product such as fruits, vegetables, plants, parts of plants, herbs, grains, tobacco, beans (including but not limited to coffee beans), seeds, medicines and anything that may be ground chopped, sliced or separated into different sizes. In certain embodiments, the Automatic Grading, Sorting and Packaging System may be used to grade, sort and package cannabis. The presently disclosed system may be used to package cannabis in the form of leaves and herbs. In certain embodiments, the bag used to package products processed through the Automatic Grading, Sorting and packaging System is a polypropylene bag.
