The machine above is another Traveling Lift Conveyor. My boss bought the top part at a used machinery auction. I added the bottom part, to make it travel on small railroad tracks. It came from an old twin beam overhead traveling crane. The next day, when the concrete is hard, we will use this Traveling Lift Conveyor to unload the boards from the conveyors. Because this machine moves automatically and could hit something left in it's path, so I have added the little gray box at the extreme left edge of this photo and a fine stranded steel cable. This system is known as a "Emergency Stop Pull Cable Switch". If something comes in contact with the small cable while it is traveling, it will pull on the Switch causing an Emergency Stop Condition. I will be installing this same system on the other Traveling Lift Conveyor.
As you can see in this photo, this is a "Scissors" type of lift. It's capable of lifting 5000 lbs. The Electrical box that you see in the foreground I built and added to this machine. The box door has been opened so that you can see the electrical equipment. As with the other Traveling Lift Conveyor, an Automation Direct 205 PLC has been added to control the functions of this machine. This PLC communicates with the rest of this machine through the little white LAN communication cable on the right. The dark bracket sticking out on the right side of this machine close to the floor are the binary Proximity switches (1, 2, 4 & 8), enabling this machine to find up to 15 positions. Other Position sensors that can't be seen in this view allow this machine to raise to 5 different positions to match the height of the 3 product Accumulation conveyors and the next machine's in feed conveyor. 2 conventional limit switches mounted on the deck above allow this machine to hold 2 boards and pass them automatically to the next machine. The Box and motor on the left end of the machine are the Hydraulic reservoir, motor & Pump.
This photo above shows things from another angle. In this view you can see that the Traveling Lift Conveyor is raised to the level of the Product/Board Separator, so that the Board from the Fleming machine can travel into the Product/Board Separator. The Product/Board Separator can de stack multiple layers of boards from their Product. If there is only one layer, then this part simply pushes the Product off the board (Right) and on to the Transfer Table, and on the way back, it pulls the board left into the Fleming Board magazine.
In this view above, it shows that the Fleming board has now been fully transferred into the Product/Board Separator. The next step for this machine, is to have the Product pusher bar come forward (toward the camera), and if the Board actually had a product such as Pavers or Meter boxes on it, they would now have been all pushed off of the board and several inches onto the transfer table plate (foreground). When the pusher bar goes back to it's normal retracted position as shown, it pulls the board into the rear part of this machine (Shown 2 photos down), which is the Fleming Board Magazine.
In this view, you can now see the Transfer Table in the foreground. The Transfer Table moves in 2 axises, up & down and back & forth. I designed it to be able to move and support 500 Lbs. In this view, it is in it's upper, rearward position, which allows it to receive products from the Fleming board. The round silver colored pipe by the front edge of the Transfer Table is the "Stripper Bar". The Stripper Bar is shown "Down", but it normally is "up", to allow the products to pass under it.
In this close up view, it shows that the pusher bar has been fully forward, and it now is returning to it's normal position, pulling the Fleming board back, and into the Fleming Board Magazine.
The view above is of the Fleming Board Magazine. The Fleming Board Magazine can hold about 25 Fleming Boards. If the forklift operator does not empty the Fleming Board Magazine before it becomes full, the machine will stop and an alarm will sound, and the red light will light on the electrical control cabinet (The red light is on top of the big Blue rectangle box standing behind the Fleming Board Magazine).
