Definitions
- Product accumulation systems are routinely used in conjunction with conveyors for the storage and accumulation of products which are fed from an upstream source onto conveyors.
- products are placed on a conveyor at the upstream location, for instance at one operational station, and then transported to a downstream location by conveyor where the next step in the manufacture or distribution of the products is to be accomplished.
- the upstream machinery can continue to operate by moving products to the accumulator. Since product movement can continue, there is no build-up of line pressure. Such a system also saves the substantial time and expense which would result in having to shutdown and then restart the entire system, if no accumulator was otherwise available.
- the downstream problem can be addressed.
- the products stored in the accumulator are released to the downstream destination, with little downtime to the system.
- Products can also be received and stored at the accumulator in case there is an upstream disruption. In this case, accumulated products could be retained and sent downstream in order to keep the system operational while the upstream problem is being remedied.
- a second type is offline storage. These devices store excess products at right angles to the line in mass. As products back up on the production line, the storage device will allow product flow out onto the planar surface, which is powered away from the line during the period of accumulation. When the stored products are called for, the planar surface reverses direction and the stored products are loaded back onto the production line. This is almost always done en mass and therefore has the same inherent problems with line pressure and single filing requirements as inline storage devices.
- a third type uses re-circulating storage.
- This type of storage device allows products to travel directly from the entry point to the exit point without interrupting the flow, until a need to store products occurs.
- products are re-circulated by means of two planar surfaces moving in opposite directions.
- Products that cannot exit the storage device are allowed to re- circulate onto the planar surface, moving in the direction which is opposite to the direction of discharge.
- This technique has been very effective in minimizing the amount of line pressure that can build up, as well as incorporating within the device the inherent ability to single file without a separate device to perform this function.
- the present invention which consists of a product conveying and accumulation system for use with products of various sizes, shapes and stability characteristics.
- the system comprises at least one product delivery conveyor which transports products from an upstream location. Another conveyor delivers products to a downstream location.
- Dual U-shaped accumulator conveyors in the system are positioned to accept upstream products from the delivery conveyors and to transport the products to the downstream conveyor.
- the dual conveyors each have straightaway conveyor sections which are aligned parallel to each other. Accumulator sections are formed at these parallel alignments. In one configuration, the two straightaway sections of one of the dual conveyors are parallel to and in adjacent alignment with the straightaway sections of the other of the dual conveyors.
- the straightaway section of one of the dual conveyors is parallel to and in adjacent alignment with one straightaway section of the other conveyor, and the other straightaway sections of the two conveyors are parallel to and in spaced relation to each other.
- Product guides are provided which allow for the movement of products from the upstream to downstream locations during normal operation and direct products to the accumulator sections. Any product which cannot be accepted downstream due to a disruption or malfunction is thus accumulated in the designated areas and such products are re -circulated to the areas and ultimately to the downstream location when the downstream disruption or malfunction is remedied.
- the conveying and accumulation system disclosed by the present invention permits product which is inherently unstable, e.g., lightweight, but top heavy plastic containers with a high center of gravity, to be received, accumulated, and re-circulated, without these products tipping, falling over, and thus disrupting the accumulation and re-circulation process.
- the configuration of the various conveying elements of the system maintains these products in their upright position throughout the accumulation and re-circulation process.
- FIG. 1 is a top view of the product conveying and accumulation system of the present invention, showing the directional movement of the conveyor components of the system.
- FIG. 2 is a top view of the product conveying and accumulation system of the present invention, showing an alternate embodiment of the present invention.
- the product conveying and accumulation system 1 of the present invention comprises separate, U-shaped conveyors 2 and 3 which are configured to assist in the movement of products from an upstream location or station designated at 4, via conveyor 5.
- Conveyor 6 is configured to move products from system 1 to a downstream location ⁇ , designated as 7.
- Conveyor 8, leading from upstream location 9 is shown to evidence that there may be alternate placement of conveyors in system 1 for the transport of products to and from the system.
- the invention is not deemed to be restrictive as to the positioning and configurations of those conveyors which provide products to system 1 from upstream to downstream destinations.
- Conveyors 2 and 3 are constructed of interlocked segments 10 which are well known in the industry.
- Conveyor 2 comprises conveyor straightaway sections 16 and 18 which are parallel to each other and are interconnected by curved end conveyor section 20.
- Conveyor 3 comprises conveyor straightaway sections 22 and 24 parallel to each other and connected by curved end conveyor section 26.
- Conveyor straightaway sections 16 and 18 of conveyor 2 and conveyor straightaway sections 22 and 24 of second conveyor 3 are parallel to each other.
- Conveyor 2 and conveyor 3 are each separate, continuous loop path conveyors.
- Conveyor 2 is powered for linear movement by well known drive means from a motor or other suitable power source 28 and conveyor 3 is powered for linear movement by well known drive means from a motor or other suitable power source 30.
- Inner guard rails 11 and 13 and outer guard rails 15 and 17 assist in receiving and maintaining product within the boundaries of conveyor 2 and conveyor 3.
- straightaway section 16 of conveyor 2 and straightaway section 22 of conveyor 3 are parallel and in substantial alignment with each other and are located in the same transverse plane.
- Straightaway section 24 of conveyor 2 and straightaway section 18 of conveyor 3 are parallel to and in substantial alignment with each other and are located in the same transverse plane.
- Accumulator section 32 is formed at straightaway sections 16 and 22 and accumulator section 34 is formed at straightaway sections 18 and 24.
- Guide 40 is designed to direct products for eventual transport onto conveyor 6 and to accumulator section 32.
- Guide 42 is designed to direct products from conveyor 3 onto accumulator section 34.
- Power sources 28 and 30 are designed to be operable at the same speed such that conveyor 2 and conveyor 3 are moving in the same direction at the parallel alignments of conveyor straightaway sections 16 and 22 and at straightaway sections 18 and 24.
- Straightaway sections 16 and 22 and straightaway sections 18 and 24, located in the same transverse plane, run adjacent to each other and move in the same direction at their parallel alignments, between locations 19 and 21 and between 23 and 25, with their respective interlocking segments 10 mated in a manner which is commonly employed in the industry.
- the directional arrows in FIG. 1 denote the direction of movement of conveyors 2, 3, 5, 6 and 8.
- conveyor 2 and conveyor 3 are optimally set to run in tandem, receiving products from conveyor 5 (and/or conveyor 8) and discharging them to downstream location 7 via conveyor 6. Products which cannot be readily accepted by conveyor 6 are directed by guide 40 onto accumulator section 32, where the products are recycled around conveyor 3 and returned to conveyor 2 for eventual transport to downstream station 7 via conveyor 6.
- guide 40 can be modified, as is known in the art, to close off product discharge to downstream 7. Then, as products continue to be delivered via conveyor 5 from upstream station 4, products are directed to accumulator sections 32 and 34, where they continue to be transported by conveyor 2 and conveyor 3. As more products are fed from upstream, an increased number of products are advantageously located and stored on conveyors 2 and 3.
- FIG. 2 shows an alternate configuration of the invention in which straightaway section 16 of conveyor 2 and conveyor straightaway section 22 of conveyor 3, while parallelally aligned, are located in spaced apart relation to each other. Positioning of these straightaway sections in this manner allows the use of downward slide transfer plate or similar slide transfer means 50, which serves to enhance the positioning of products for accumulation and eventually transport downstream.
- straightaway section 22 is located below straightaway section 16, being within a lower but parallel transverse plane, than the transverse plane within which section 16 is located.
- the speed of the upstream product feed and downstream product supply are designed to be adjusted, depending on the type of product and the location of the constraint. For optimal operation, there should always be sufficient accumulated product in system 1, such that the upstream product feed is adjusted to equate to the downstream flow of the product.
- An additional benefit derived from conveying and accumulation system 1 is obtained by a reduction of noise level and product damage during system operation.
- Products which are moved on prior conveyor systems tend to contact each other, especially at turns in the conveyor.
- the constant speed at which conveyors 2 and 3 travel causes the outboard product to become spaced apart from the inboard products. This reduces product contact and its resulting noise, and also helps to eliminate product and product labeling damage caused by product to product contact.
- guides 40 and 42 as shown may optimally be used for certain designated products. However, there may be other product guide configurations which are unique to and work best for individual products. The herein application is not to be considered restrictive as to the guide configurations which may be used.
