The present disclosure relates generally to container filling systems and methods, and more particularly to a fluid filling line configured to continuously and simultaneously fill multiple containers of different shapes and/or sizes with a common fluid.
The term “coating product” is used to cover a variety of liquid coating materials such as paints, enamels, lacquers, varnishes, under coats, surfaces, primers, sealers, fillers, and stoppers. Most coating products contain a pigment, a resin polymer which acts as a film-former and in a coalesced applied coating film a binder to bind the pigment particles together, and water or solvent as a diluent. Coating products are often available in many different colors sheens (e.g., gloss, semi gloss, satin, and flat), quality levels (e.g., good, better and best), uses (e.g., indoor/outdoor, rust inhibiting, adhesion to particular surfaces, etc.), and quantities (e.g., quart, gallon, 5-gallon, etc.).
To meet customer needs, manufacturers offering all combinations of these colors, sheens, quality levels, uses, and quantities need to produce and handle a wide variety of coating products. From a manufacturing perspective, a significant investment in equipment may be necessary to handle the production of coating products.
Over the years, various machines for the batch manufacturing and packaging of coating and other liquid products have been developed. Two such machines common to the industry are in-line fillers and rotary fillers. With both types of fillers, a series of empty containers (e.g., cans or other vessels) are fed into the machine and conveyed along a feed track to be positioned beneath a dispensing nozzle. With in-line fillers, the container pauses beneath the dispensing nozzle while the container is filled. With rotary fillers, the dispensing nozzle rotates about a common axis with the container during the fill process, thereby enabling a more continuous throughput in comparison to in-line fillers.
In some cases, a plurality of dispensing nozzles, solenoid valves, or the like can be controlled for the automatic formulation of a particular coating or other liquid product as the coating containers are being filled. However, more commonly with batch systems, the coating or other liquid product is produced in a quality controlled batch of a given quantity, which is then used to fill the containers. During the fill process, various sensors can be utilized to ensure that the container has been filled to the appropriate level. A cover or lid can then be placed on the container and secured in position, thereby sealing the product within the container. Thereafter, the containers are conveyed along a track to a packing and distribution portion of the production line.
Although such batch manufacturing systems have proven effective in enabling manufacturers to readily fill containers with liquids such as, e.g., coating products of varying color, sheen, quality level, and use, these systems are typically not accommodative to multiple different sizes of containers. That is, typically each batch filling machine is only adapted to accommodate a specific container size. Accordingly, either separate batches of coating or other liquid product must be produced to accommodate each production line, or the batch must be “split” between the production lines for different sized containers. Further, having separate fill lines for each size container significantly adds to the required space and investment in manufacturing equipment necessary to handle a wide variety of coating or other liquid products.
Although the systems and methods described herein may be particularly useful for packaging coating products in containers, the systems and methods may be equally useful in packaging any liquid product in suitable containers, e.g., liquid hand sanitizer or other personal care products, solvents (e.g., like acetone, methyl ethyl ketone (MEK), xylene, mineral spirits, alcohols, etc.), stripping products (e.g., products used to remove coatings, etc.), cleaning/sanitizing products, food products (e.g., beverages, condiments, etc.), motor vehicle products (e.g., motor oil, transmission fluid, brake fluid, coolants, etc.), and many others.
Embodiments of the present disclosure provide a continuous rotary split fill apparatus configured to enable the continuous and simultaneous filling of multiple containers of different shapes and sizes with a common batch of coating or other liquid product on a single, compact manufacturing line, thereby both minimizing the production time, required space and investment in manufacturing equipment necessary to handle a wide variety coating or other liquid products.

The summary above is not intended to describe each illustrated embodiment or every implementation of the present disclosure. The figures and the detailed description that follow more particularly exemplify these embodiments.
The disclosure can be more completely understood in consideration of the following detailed description of various embodiments of the disclosure, in connection with the accompanying drawings, in which:
While embodiments of the disclosure are amenable to various modifications and alternative forms, specifics thereof shown by way of example in the drawings will be described in detail. It should be understood, however, that the intention is not to limit the disclosure to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.
Referring to
In general, the fluid production line 100 can include two or more feed conveyors 104A-C (collectively referred to as a feed conveyor mechanism 104), which converge at the rotary split filler 102, and then separate into two or more output conveyors 106A-C (collectively referred to as an output conveyor mechanism 106).
Each feed conveyor 104 and corresponding output conveyor 106 can be configured to accommodate a fluid container of a particular size. For example, in one non-limiting embodiment, the first feed conveyor 104A and corresponding first output conveyor 106A can be configured to accommodate containers having a normal internal fill volume of approximately 1-quart. The second feed conveyor 104B and corresponding second output conveyor 106B can be configured to accommodate containers having a normal internal fill volume of approximately 1-gallon. The third feed conveyor 104C and corresponding third output conveyor 106C can be configured to accommodate containers having a normal internal fill volume of approximately 5 gallons. Other conveyor configurations and container sizes are also contemplated. For example, the containers can have a normal internal fill volume of about ½-pint (0.24 L), 1-pint (0.47 L), 1-Liter, 1-quart (0.95 L), 1-gallon (3.79 L), 4-liters, 5.3-liters, 5-gallons (18.93 L), 20-liters, or any other desirable volume, and based on US fluid ounces, with the non-SI unit volumes being US or imperial units of measure as desired. The containers can be constructed of metal, glass, or plastic, and can have press-fit or screw-top lids or caps. Suitable containers of different shapes and sizes for use in the disclosed fluid production line 100 are available from a variety of suppliers, including BWAY, CARY CO., KW CONTAINER, and UNIVERSAL CAN CO., to name just a few.
In some embodiments, coating and other liquid products can be packaged in containers suitable for small batch lots. In the case of coating products, depending on the amount of pigmentation (e.g., white pigmentation) already present in a coating product, the container can have a small amount of headspace for colorant addition. For example, a one gallon (3.79 L) white base paint container can hold about 128 oz. (3.79 L) of the base paint, with only a small headspace volume available for colorant addition. A one gallon (3.79 L) clear base paint container can for example hold about 116 oz. (3.43 L) of a base paint, with about 12 oz. (0.35 L, or about 9% of the total container volume) of headspace available for colorant addition. When additional base paints of intermediate opacity are employed, they likewise can have intermediate available headspace volumes for colorant addition. For example, a four base system can employ the white and clear base paints mentioned above, together with a pastel base whose container has about 126 oz. (3.73 L) of base paint with about 2 oz. (0.06 L) of headspace available for colorant addition, and a standard color base whose container has about 124 oz. (3.57 L) of base paint with about 4 oz. (0.12 L) of headspace available for colorant addition.
As further depicted in
Similarly, the third feed conveyor 104C can originate at a container preparation station 108B, which in some embodiments can be configured to de-nest 5-gallon containers (which may be empty). Thereafter, the containers can proceed to a labeling station 112C (which optionally can be positioned further downstream). Thereafter, the containers of different sizes can be conveyed along the respective first, second and third feed conveyors 104A-C to the rotary split filler 102.
Downstream of the rotary split filler 102, filled containers transported along the first output conveyor 106A can pass through a lidder station 114A, configured to secure a lid or cover onto the filled container, thereby safely and securely sealing the coating product within the container. The sealed, filled containers can then progress to a case packer station 116A configured to bundle the filled containers together in a desired quantity. The cases of filled containers can then proceed to a rotary elevator 118A to a distribution portion 120 of the fluid production line 100.
Similarly, downstream of the rotary split filler 102, filled containers transported along the second output conveyor 106B can pass through a lidder station 114B. Where it is desired to position a handle on the container, the containers can pass through a bailing station 122. In some embodiments, the second output conveyor 106B can be divided to pass through a pair of bailing stations 122A/B operating in parallel. The filled containers can proceed on to a case packer station 116B, a rotary elevator 118B, and to a distribution portion 120 of the fluid production line 100. Likewise, downstream of the rotary split filler 102, filled containers transported along the third output conveyor 106C can pass through a lidder station 114C, and a rotary elevator 118B to the distribution portion 120 of the fluid production line 100.
It is noted that the fluid production line 100 depicted in
The feed conveyor, output conveyor and other container handling stations and components of the fluid production line 100 can be provided by a number of filling equipment manufacturers. Suitable manufacturers include FEDERAL MANUFACTURING CO., FILAMATIC, APACKS, UNIVERSAL FILLING, E-PAK MACHINERY, INC., and FRAIN INDUSTRIES, to name just a few. After reviewing this disclosure, suitable filling equipment manufacturers of ordinary skill will be able to fabricate a fluid production line 100 including a rotary split filler 102, as described herein.
With reference to
Each ring/section 126 of the turntable mechanism 124 can be configured to accommodate a fluid container of a particular size. For example, in one non-limiting embodiment, the first ring/section 126A can be configured to receive empty containers 200A of a first size from the first feed conveyor 104A and deliver filled containers 201A of the first size to the first output conveyor 106A.
In some embodiments, one or more of the feed conveyors 104A-C can be positioned radially with respect to the common axis 128, so as to extend radially outward from the turntable mechanism 128. As further depicted in
As depicted, the feed conveyors 104A-C can include a section having a pair of opposed helical screws 130 configured to separate empty fluid containers 200A-C from one another by a predefined distance (D) during transport along a portion of the fluid production line 100. Other transport mechanisms, such as a traditional conveyor belt, roller bed or gravity fed system are also contemplated.
In some embodiments, one or more of the output conveyors 106A-C can be tangentially positioned with respect to the respective sections 126A-C of the turntable mechanism 124, thereby enabling a smooth transition of the filled fluid containers 200A-C as they pass from the turntable mechanism 124 to the respective output conveyor 106A-C. Like the feed conveyors 104A-C, the elevation of the output conveyors 106A-C can be configured to enable the tops, bottoms or fill line levels of the fluid containers 200A-C to remain level with respect to a gravitational frame of reference throughout the filling process. The output conveyors 106A-C can utilize any of a number of transport mechanisms to convey the filled containers 200A-C along the fluid production line 100, such as a conveyor belt, roller bed, opposed helical screws, gravity-assisted system, or the like.
The rings/sections 126A-C of the turntable mechanism 124 can be configured as concentric rings. For example, as depicted, the first section 126A can be configured as a ring surrounding the common axis 128. The second section 126B can be configured as a ring concentrically surrounding the first section 126A. The third section 126C can be configured as a ring concentrically surrounding the second section 126B. Collectively, the first, second and third sections 126A-C can rotate about the common axis 128.
In other embodiments, the rings/sections 126A-C can rotate at their own respective rotational rates, thereby, for example, enabling the filling of containers of a first size 200A at a faster rate than containers of a second or third size 200B/C. In other embodiments, any two or more of the sections 126A-C can be collectively synced together to rotate in unison at the same rate of rotation. For example, in one embodiment, the various sections 126A-C can be integrally formed into a single piece, unitary turntable 124. In some embodiments, the time necessary to fill containers of different sizes can be compensated for by the spacing afforded by an increased circumferential distance of the larger concentric sections 126B/C, by adjustment of the flow rates through the nozzles 132A-C, by spacing of the containers as determined by the feed conveyors 104A-C, or a combination thereof.
As depicted, each of the first, second and third rings/sections 126A-C include a plurality of fluid container receptacles 134A-C configured to optimally position the respective fluid containers 200A-C on the turntable mechanism 124. As further depicted in
In one or more embodiments, the tops, bottoms, or fill line levels of the fluid containers 200A-C may remain level with respect to a gravitational frame of reference throughout the filling process. In one or more embodiments, the various rings/sections 126A-C of the turntable 124 a may lie in a common substantially horizontal plane.
As depicted in
In some embodiments, at least one fill valve 132A-C and its respective fill port can be positioned above each fluid container receptacle 134. In some embodiments, multiple fill valves, fill ports or orifices can be positioned above each container receptacle 134. In some embodiments, the fill vessel 136 can be configured to rotate about the common axis 124 at the same rate as the turntable mechanism 124 or the respective sections 126A-C, such that a given fill valve 132 remains over a given fluid container receptacle 134 during collective rotation of the turntable 124 and fill vessel 136, thereby enabling continuous filling of the containers and eliminating the need to pause or ratchet the turntable underneath the fill valves 132 during the container filling process.
As depicted in
As depicted, each of the first, second and third sections 126A-C can include a total of ten fluid container receptacles 134A-C; although other quantities of fluid container receptacles 134 are also contemplated. For example, in another embodiment, the first section 126A can include sixteen 1-quart sized fluid container receptacles 134A, the second section 126B can include twelve 1-gallon sized fluid container receptacles 134B and the third section 126C can include eight 5-gallon sized fluid container receptacles 134B. In yet another embodiment, in an effort to maximize production, the quantity of fluid container receptacles 134A-C can be determined based on the respective fill rates of the containers. For example in one embodiment, the number of fluid container receptacles 134A-C and the respective rotational speeds of the various sections 126A-C of the turntable 124 can be adjusted to simultaneously fill about forty-eight 1-quart containers, about thirty-six 1-gallon containers, and between about twenty and twenty-four 5-gallon containers each minute.
Accordingly, through the use of a multi-section 126 rotary split filler 102, the fluid production line 100 is configured to continuously fill multiple different sizes of containers in parallel, thereby not only enabling the different sizes of containers to be simultaneously filled with a common batch coating product 101, but also significantly decreasing the production time necessary to fill the containers. For example, in some embodiments, the fluid production line 100 can be configured to simultaneously fill containers of various sizes at a rate of approximately 168 gallons per minute. For higher viscosity fluids, such as thick paints and other coating products, the fill rate may be in a range from about 140 gallons per minute to about 155 gallons per minute. Other fill rates are also contemplated. For example, in some embodiments, the total fill rate from the common batch of fluid can be at least about 50 gallons per minute, at least about 80 gallons per minute, at least about 110 gallons per minute, or at least about 140 gallons per minute, and up to about 100 gallons per minute, up to about 130 gallons per minute, up to about 160 gallons per minute, or up to about 190 gallons per minute.
In operation, multiple empty fluid containers of different sizes 200A-C can be transported to the rotary split filler 102 via respective separate feed conveyors 104A-C (collectively referred to as a feed conveyor mechanism). Each of the feed conveyors 104A-C can be configured to position the containers of different sizes 200A-C on respective separate sections 126A-C of the turntable mechanism 124, beneath a respective fill valve 132A-C. The sections 126A-C of the turntable mechanism 124 can rotate about a common axis 128 while the containers of different sizes 200A-C are simultaneously filled with a designated quantity from a common batch of fluid. Upon completion of filling, the turntable mechanism 124 can deliver the filled fluid containers 200A-C of different sizes to respective separate output conveyors 106A-C for further transport along the fluid production line 100.
In some embodiments, filling operations on any one of the respective rings/sections 126A-C can be selectively turned on or off as desired. This may be useful where, for example, the desired number of containers of one size (e.g., the largest containers) on one of the rings/sections 126A-C has been filled (or, alternatively, when the desired number of containers of two different sizes on two different rings/sections 126A-C have been filled), but filling of containers of one or more other sizes is to be continued on the remaining rings/sections 126. In one or more embodiments, the rate at which the containers in the remaining rings/sections 126 may increase after filling of one or more selected rings/sections 126 has been turned off. That increased fill rate may allow for an increase in the rate at which the containers are filled and transferred to the output conveyor(s) 106A-C (which corresponds to an increased rotational speed of the remaining rings/sections 126).
In one illustrative embodiment of such an increase in fill rate associated with terminating the filling of containers on one ring/section in which containers of three different sizes (e.g., quart, gallon, and five gallon containers) are being filled, the rings/sections 126A-C may be rotated at a speed of one revolution per minute (rpm) while a cumulative flow rate of liquid delivered to the containers is 120 gallons per minute (gpm) (with 94 gpm delivered to the 5-gallon containers, 20 gpm delivered to the gallon containers, and 6 gpm delivered to the quart containers). When the desired number of 5-gallon containers have been filled, the fill valves used to deliver liquid to the ring/section carrying the 5-gallon containers are closed. At that point, the cumulative flow rate of 120 gpm may be maintained while the speed at which the rings/sections carrying the quart and gallon sized containers rotate may be increased to, e.g., 2.7 rpm (with 104 gpm delivered to the gallon containers, and 16 gpm delivered to the quart containers). Increasing the rotational speed of the rings/sections will typically require corresponding increases in the rate at which the containers are delivered to and removed from the rings/sections, as well as increases in the speed at which the fill valves and fill vessel are rotated.
Although the depicted illustrative embodiments of the filling apparatus and the fluid production lines described herein are configured to fill containers having three different sizes on three different rings/sections, one or more alternative embodiments of the filling apparatus and/or fluid production lines described herein that include three (or more) different rings/sections rotating about a common axis may include two rings/sections that are configured to fill containers of the same size while the third ring/section is configured to fill containers of a different size than the same-sized containers filled on the two rings/sections. For example, in a filling apparatus and/or fluid production line in which two rings/sections are configured to fill gallon size containers (with appropriate feed and output conveyors), one or more additional rings/sections may be configured to fill quart size containers, 5-gallon containers, etc.
