Abstract

A unified docking apparatus is provided. It includes a single set of controls to operate a vehicle restraint, a dock door, a barrier device, a dock seal, and a loading light. Some optional embodiments include selector switch to select which apparatus the single set of controls will control. Other optional embodiments automatically select the apparatus to be controlled by the single set of controls. A method of operating a docking apparatus using a single set of controls is also provided.

Claims

1. An automatic loading dock controller, comprising:

(c) a first operation control attached to the control panel, wherein the first operation control, when activated, engages a vehicle restraint, opens a dock door, raises a dock leveler and lowers the dock leveler to an operative or stored position, and extend and retract a lip portion of the dock leveler;

(d) a second operation control attached to the control panel, wherein the second operation control, when activated, closes a dock door, and disengages a vehicle restraint;

(e) a programmable controller configured to selectively cause the first operation control to control the vehicle restraint, the dock door and the dock leveler according to a preprogrammed program, and selectively cause the second operation control to control a lip portion of a dock leveler, close the dock door and disengage a vehicle restraint according to a preprogrammed program;

(f) a third operation control attached to the control panel, wherein the third operation control is an emergency stop control configured to stop operation of the loading dock apparatus; and

(g) a vehicle restraint bypass switch located on the control panel, wherein the vehicle restraint bypass switch is configured to selectively bypass the dock loading apparatus causing the controller to not engage and disengage the vehicle restraint to a vehicle, but activate the operator control signal light to indicate at least one of loading dock ready for loading, operator be cautioned; and

loading dock not ready for loading, and proceed with a next operation in a sequence of operations.

2. The automatic loading dock controller of claim 1, further comprising a selectable manual bypass vehicle restraint control configured to select between at least one of release, automatic, and engage, wherein when the selectable manual vehicle control set for release, the vehicle restraint disengages when the selectable manual vehicle control is set for automatic, the vehicle control performs according to a predetermined schedule, and when the vehicle release control is set for engage, the vehicle release engages.

3. The automatic loading dock controller of claim 1, further comprising a selectable manual override door control configured to select between at least one of close, automatic, and open, wherein when the selectable manual door control is set for close, the dock door closes, when the selectable manual door control is set for automatic, the dock door performs according to a predetermined schedule, and when the door control is set for open, the dock door opens.

4. The automatic loading dock controller of claim 1, further comprising a selectable manual override loading light control configured to select between at least one of on, automatic, and off, wherein when the selectable manual loading light control is set for on, a loading light turns on, when the selectable manual loading light control is set for automatic, the loading light turns on when the dock door opens and turns off when the dock door closes, and when the loading light control is set for off, the loading light turns off.

5. The automatic loading dock controller of claim 1, wherein the controller also controls a barrier gate, when the vehicle restraint is engaged or bypassed, the barrier gate disengages, when the vehicle restraint is disengaged, the barrier gate engages.

6. The automatic loading dock controller of claim 5, further comprising a selectable manual override barrier gate control configured to select between at least one of engage, automatic, and disengage, wherein when the selectable manual barrier gate control set for engage, the barrier gate is engaged, when the selectable manual barrier gate control is set for automatic, the barrier gate performs according to a predetermined schedule, and when the barrier gate control is set for disengage, the barrier gate control disengages.

7. The automatic loading dock controller of claim 1, wherein the controller further controls a door seal, wherein the door seal automatically inflates when the vehicle restraint engages or bypassed, and deflates when a vehicle restraint is disengaged.

8. The automatic loading dock controller of claim 7, further comprising a selectable manual override door seal control configured to select between at least one of inflate, automatic, and off, wherein when the selectable manual door seal is set for inflate, the door seal inflates when the selectable door seal is set for automatic, the door seal performs according to a predetermined schedule, and when the door seal control is set for off, the door seal deflates.

9. The controller of claim 1, further comprising a selector switch located on the control panel for selectively operating docking loading apparatus for different docking bays.

10. An automatic loading dock controller, comprising:

(a) a control panel for providing a common area for operator controls and signals;

(b) operator signal lights located on the control panel and operatively connected to the loading dock apparatus for signaling an operator that a loading dock is at least one of ready for loading, not ready for loading, and operator be cautioned;

(c) means for controlling the docking apparatus attached to the control panel, wherein the means controls a vehicle restraint, controls a dock door, controls a dock leveler, and controls a lip portion of the dock leveler;

(d) a programmable controller configured to selectively cause the means for controlling the dock loading apparatus to control the vehicle restraint, the dock door, and the dock leveler according to a preprogrammed program;

(e) an emergency stop attached to the control panel, configured to stop operation of the loading dock apparatus; and

(f) a vehicle restraint bypass switch located on the controller, wherein the vehicle restraint bypass switch is configured to selectively bypass the dock loading apparatus causing the controller to not engage and disengage the vehicle restraint to a vehicle, but activate the operator control signal light to indicate at least one of loading dock ready for loading, operator be cautioned, and proceed with a next operation in a sequence of operations, when the vehicle restraining apparatus is attached to a vehicle or is bypassed and the operator control signal light to display the signal the loading dock not ready for loading when the vehicle restraining apparatus is not engaged and not bypassed.

11. The automatic loading dock controller of claim 10, further comprising a selectable manual bypass vehicle restraint control configured to select between at least one of release, automatic, and engage, wherein when the selectable manual vehicle control set for release, the vehicle restraint disengages, when the selectable manual vehicle control is set for automatic, the vehicle control performs according to a predetermined schedule, and when the vehicle release control is set for engage, the vehicle release engages.
