Shoe cover removal apparatus
An apparatus which includes a trough for receiving a user's shoe. The trough includes a removal portal. The apparatus includes a vacuum capable of causing a shoe cover to be removed from the shoe of a user when a user places a shoe covered by a shoe cover into the trough. An actuator is triggered by the placement of an object in the trough, the triggering of the actuator causing the vacuum to activate. The vacuum activation causes the shoe cover to be sucked through the removal portal and into a primary chamber. The primary chamber collects the removed shoe covers and is disposed in a remote from the trough for preventing debris and other contaminants from being stored in a clean room. The apparatus may also include multiple troughs connected to one or more primary chambers.
1. A method of using an apparatus for removing a shoe cover from a user's shoe, the apparatus comprising an open trough for receiving a user's shoe, the trough including sidewalls, an open top area defined by upper edges of the sidewalls, and a bottom surface; a removal portal located within the trough; a vacuum including a motor, a suction portal, and a exhaust portal; a primary chamber including a lid, a primary chamber input portal, and a primary chamber output portal, the primary chamber for receiving and retaining removed shoe covers, the primary chamber input portal being connected to the removal portal, and the primary chamber output portal being connected to the suction portal of the vacuum; an actuator that it is activatable by the placement of an object in the trough, and a first filter for removing debris and other contaminants from gas passing through the apparatus when the vacuum is activated, wherein the first filter comprises a porous collection container removably located in the primary chamber, the porous collection container for collecting removed shoe covers and preventing removed shoe covers from obstructing the primary chamber output portal, the method comprising the steps of:
(a) inserting a shoe at least partially covered by a shoe cover into the trough such that the shoe is adjacent the removal portal;
(b) detecting the shoe when it placed into the trough using a detection system;
(c) actuating the vacuum device such that it creates a vacuum in the primary chamber and at the removal portal;
(d) removing the shoe cover from the shoe via the removal portal with the vacuum created at the removal portal;
(e) receiving and retaining the shoe cover in the primary chamber; and
(f) removing the porous collection container from the primary chamber for disposal of the removed shoe covers.
2. The method of claim 1 , further comprising the step of, after step (e):
(g) removing the shoe from the trough; and
(h) detecting that the shoe is not longer located within the trough; and
(i) deactuating the vacuum device.
3. The method of claim 1 , wherein the detection system is a motion detection system and the detecting step comprises detecting motion of the shoe entering the trough.
4. The method of claim 3 , wherein the motion detection system is an infrared light detection system.
5. The method of claim 1 wherein the removal portal is unobstructed above a top portion of the removal portal and step (d) further comprises the shoe cover being removed from the shoe directly through the top portion of the removal portal.
6. The method of claim 1 , wherein the apparatus further comprises a second filter, wherein the second filter is a high efficiency particulate air filter.
7. The method of claim 1 , wherein the apparatus further comprises a second filter, wherein the second filter is a cylindrical filter located in the primary chamber.
