Description

FIELD OF THE DISCLOSURE

This disclosure relates to an improved bulk bin lid opener system for controlling access, remotely opening and closing, and easily disconnecting the actuator if manual operation is required.

BACKGROUND OF THE DISCLOSURE

To continuously improve bio-security in the food supply chain, control and monitoring is being extended to all input activities related to production. Today, personnel movement between facilities is monitored to prevent entry into a non-infected facility after exposure to infected facility. One input in the production of protein is the feed supplies which are delivered by a common truck and driver to bulk feed bins located on the property outside of the production building. A truck and driver travel to and between disease infected facilities and non-infected facilities on the same route potentially spreading disease.

The disease transfer could occur due to cross traffic at the bulk bin installation location. When feed is delivered, the driver must exit the truck to open the bin lid, transfer feed from the truck, and close the lid. The transfer of disease to the facility occurs when bulk bins are inspected or serviced by facility staff who then re-enter a production facility. Current practices at bulk bin installation locations do not sufficiently limit or eliminate cross-traffic contamination. Additionally, current practices do not provide information about facility traffic.

Pavlicek, U.S. Pat. No. 4,267,936, and Pollock, U.S. Pat. No. 5,218,784, teach the most common method to open a bulk bin lid, a chain that extends from the lid down the side of the bulk bin. To fill the bulk bin the driver exits the vehicle, pulls on the chain and secures it to a latch. When the delivery is complete, the chain is released and the lid closes. This method does not allow for remote control and activation as required by modern bio-security requirements.

Thompson, U.S. Pat. No. 4,625,888, and Christianson, U.S. Pat. No. 4,747,244 teach complex and impractical methods of cranks, pulleys, cables and slides to open and close a bulk bin lid from the ground.

Poncsak, U.S. Pat. No. 9,919,867, teaches a method for opening and closing a bulk storage bin using a linear actuator mounted at the top of the bin and directly connected to the lid. The actuator is activated by a control box which can be controlled remotely by electronic communications. The installation and service of a top mounted system makes this solution, especially difficult and costly for retrofitting to a current system and requires high safety precautions during installation. The taught method is rigidly connected and cannot be disconnect without climbing to the bin top. Therefore, in the case of a power failure or other problem the lid is inoperable.

Therefore, for all the reasons stated herein, there is a need for a better remotely mounted actuator that will open and close a storage bin lid on new or retro fit bulk tank applications, which is easily installed and serviced from a near ground location and can be operated manually in the event of a system failure.

Thus, it is an object of the disclosure to mount the bin lid actuator at or near ground level.

Another object of the disclosure is no requirement to drill any additional holes in structure or bin.

Yet another object of the disclosure is the lid can still be opened manually without disconnecting.

Another object of the disclosure is the actuator can be disconnected from the bin lid without tools.

Yet another object of the disclosure is to function in all environmental conditions, such as snow, ice, water, wind, and extreme temperatures.

Another object of the disclosure is to minimize parts.

Yet another object of the disclosure is to minimize the number of components.

Another object of the disclosure is to simplify assembly.

Yet another object of the disclosure is minimizing actuator stroke required.

Another object of the disclosure is a mechanical override means and method.

Yet another object of the disclosure is the central control box can be controlled remotely.

Another object of the disclosure is the central control box can be controlled manually.

Yet another object of the disclosure is the central control box can be connected to as many actuators as a site requires.

Another object of the disclosure is safe to service.

Another objective of the disclosure is to associate the operation of the device to an overall digital biosecurity system to record the driver's and/or feed truck's presence on the site and that visits impact to biosecurity.

Another objective of the disclosure is to associate the operation of the device to a particular feed delivery order to assure the driver, upon operation of the control box, is at the correct site.

BRIEF SUMMARY OF THE DISCLOSURE

The disclosure relates to a bulk storage bin and delivery system installation used to store and deliver granular products to manufacturing or production systems such as feed processing or animal production in confinement buildings. The granular material is top loaded into a bulk storage bin when an input bin lid is opened by pulling and latching a lid cable, chain, or other tension force member. When loading is complete, the input bin lid is returned to a closed position with restitution force(s) which may be singular or a combination of torsion, compression or tension spring and gravitational force when the at least one cable is released. A guide channel plate comprises an elongated member, a first guide channel comprising a first slot formed within and along the length of the guide channel plate, and a second guide channel comprising a second slot formed within and along the length of the guide channel plate and parallel to the first guide channel slot. A block plate fits within the first and second guide channels and is secured by a block plate clamp. The block plate connects to a linear actuator that is secured to a support member of the bin. A slide block fits compressively within the first and second guide channels thus securing a flexible link assembly and wherein the slide block connects to the linear actuator. A connector plate allows connecting and disconnecting of the linear actuator.

The knowledge of herd health and a method to restock feed bulk bins without exiting the truck would eliminate the exposure between facilities. Furthermore, the development and deployment of unique delivery sequences to service infected and non-infected herds eliminate cross site vehicular traffic. For example, all non-infected barns are delivered first and then the infected barns, followed by truck cleaning and disinfection procedures; or trucks are restricted to specific barn infections and never enter a healthy site.

The at least one linear actuator 31 can be single acting when closing forces are sufficient enough to close the at least one bin lid 17 and collapse the actuator 31.

As shown in FIG. 5, the at least one guide channel plate 33 is formed or extruded to create at least one guide channel 34 and an apposing guide channel 34. An actuator relief cut 35 allowing the positioning the at least one linear actuator 31 to axially aligned with the intersection of the horizontal plane 67 and the vertical plane 69 of the apposing guide channel 34. The at least one block plate clamp slot 48 extends through parallel surfaces of the at least one guide channel 34. This structural support on both sides of the at least one guide channel 34 provides required structural support to secure the at least one block plate 45 when the at least one linear actuator 31 is energized.

Similarly, the at least one guide channel clamp slot 64 allows the at least one guide channel clamp tab 65 of at least one guide channel clamp 63 to intersect and secure to the at least one guide channel 34 forming an assembly. The at least one block plate clamp tab 49 and the at least one guide channel clamp slot tab 65 are twisted, folded, bent, or deformed after insertion to prevent removal.

As shown in FIG. 7, the at least one block plate 45 is connected to the at least one linear actuator 31 non-rod end and secured with the at least one pin 75 and hairpin cotter pin 77. The at least one linear actuator 31 extending rod end is connected to the at least one slide block 61 and secured with the at least one pin 75 and hairpin cotter pin 77. The at least one block plate 45 and the at least one slide block 61 are a material that will not damage the at least one flexible link assembly 70, such as ultra-high molecular weight polyethylene (UHMW).

As shown in FIG. 8, the at least one slide block 61 is compressively constrained within the apposing guide channels 34 due to a compressible section 62. The compression force is created by relieving the sides requiring deflection to position in the apposing guide channels 34 and ensuring an interference fit. The compressive contact between the at least one compressible section 62 with the surface of the at least one guide channel 34 ensures the flexible link assembly 70 is properly positioned and constrained. The at least one slide block 61 has at least one flexible link assembly guide channel 66 which symmetric to the horizontal plane 67 and arcs around the end of the at least one slide block 61 approximately 180 degrees.

In one embodiment the at least one flexible link assembly 70 is a length of wire rope 71 with a wire rope stop 73 compressed on each end. The at least one flexible link assembly extends through a hole or profile in the at least one block plate 45 extending to and around the at least one slide block 61 wraps around and constrained in the at least one flexible link assembly guide channel 66, then extending opposite and parallel through a hole or profile in the at least one block plate connecting to the at least one connector plate 27. The at least one flexible link assembly 70 is disclosed as a cable assembly, but could be a tape, rope, or other flexible two force member without departing from the scope of the disclosure.

FIG. 9 shows a sectional view of the at least one slide block 61 in compression against the at least one guide channel 34 and the at least one flexible link assembly 70 wrapped around the at least one flexible link assembly guide channel 66.

The disclosed solution by looping the at least one flexible link assembly 70 around the at least one slide block 61 and connecting to the at least one lid cable 21 doubles the at least one linear actuator 31 stroke length. This amplification of stroke does reduce the at least one actuator 31 maximum force in half. The at least one actuator assembly 30 mounted in a near ground location provides a reliable, compact, and safe to service solution. When the control receives a manual or remote signal the linear actuator 31 extends at a predetermined stroke length. The solution provides a durable and cost-effective method to open granular material bin lids and improving the bio-security of existing and new bulk material bin installations.

The at least one flexible link assembly 70, the at least one connector plate 27, and the existing lid cable 21 provide needed flexibility for correct installation and lid opening angle. For instance, if the total stroke of the actuator results in a lid angle to great an adjustment at the at least one connector plate 27 is made, the at least one flexible link assembly 70 extends below, not in contact with the at least one slide block 61. This is acceptable since the at least one flexible link 70 is retained in proper location by the compressive contact between the at least one slide block 61 and the at least one guide channel 34. Upon energization, the at least one linear actuator 31 extends until contact with the at least one flexible link assembly 70 occurs and the at least one input bin lid 17 opens.

The closed bulk storage bin installation 10 has many benefits and advantages including, but not limited to controlling access, remotely opening and closing, and easily disconnecting the actuator if manual operation is required. These and other benefits and advantages are apparent from the specification and claims.
