This patent application is a non-provisional of U.S. Patent Application No. 61/598,724 entitled “Apparatus For Counting Deposit Beverage Containers,” filed Feb. 14, 2012.
The field of the invention relates generally to container counting devices, and more specifically to apparatus for counting deposit beverage containers.
Certain types of beverage containers, such as bottles and cans, are made of recyclable materials such as aluminum, glass, or plastic. These containers can often be redeemed by consumers for money or other forms of compensation, wherein the redemption value is typically calculated on a per unit basis. Sometimes, the redemption value may be calculated by weight, but this method may result in inaccurate redemption values or require more work by consumers and redemption centers. For example, the presence of fluid in containers would increase the overall weight and redemption value of a collection of containers beyond their actual redemption value. In addition, the redemption value of different materials of equal weight may differ, and thus require consumers or redemption centers to take the extra step of sorting containers by material composition (e.g., glass, plastic, metal) before they are weighed.
Calculating the redemption value of containers on a per unit basis avoids these aforementioned issues but comes with its own set of issues. Manual counting of containers is time-consuming and labor-intensive. Furthermore, counting containers by hand, especially large quantities, is prone to errors.
An apparatus for counting deposit beverage containers that includes a loading basin for holding a plurality of deposit beverage containers, a feed chute for receiving the containers from the loading basin having an inlet end narrowing into at least one outlet end, and at least one feed channel extending from each outlet end. The feed channel includes a choke opening that orders the containers into a single file row, an upward bend following the choke opening that decreases the downward slope of the feed channel to moderate the flow of the containers, and a downward curve following the upward bend that accelerates each container to create separation between containers.
In one embodiment of the apparatus, the feed channel may include a bottom panel having a V-shaped contact surface, a low-friction contact surface, a liner insert, or a plurality of ribs extending upwards and aligned with the longitudinal axis of the feed channel.
In another embodiment of the apparatus, the radius of the downward curve is greater than about four inches.
In another embodiment of the apparatus, the loading basin of the apparatus may include a retaining member for guiding containers into the feed chute, an angled member for controlling the flow rate of containers into the feed chute, or transverse wheels for rotating a bin within the loading basin to control the flow rate of containers into the feed chute.

Illustrated in
a show an exemplary embodiment 10 of the deposit beverage container counting apparatus. The counting apparatus 10 includes a loading basin 20 for holding a plurality of deposit beverage containers to be counted by the counting apparatus, a feed chute 40 for merging the plurality of deposit containers received from the loading basin 20 into one or more rows 2 of deposit containers 4, and one or more feed channels 50 for receiving a row 2 of deposit containers 4 and conveying the deposit containers to a sensor assembly 84 which is used to sense the presence of a deposit container 4 in the feed channel 50 and to supply a signal to an electronic counting device in a control panel 35 which update the count and provides an updated signal to one or more output displays 39.
In the embodiment shown, the loading basin 20 includes a cradle 22 which supports and lifts a removable bin 26 holding the deposit containers 4 to a position above the feed chute 40 and feed channel(s) 50, so that the deposit containers 4 fall out of the removable bin 26 and slide down the feed channel(s) 50 under the force of gravity. In some aspects the removable bin 26 can include the standard 32-gallon plastic barrels commonly used at redemption centers. The cradle 22 has wheels mounted transverse to the longitudinal centerline of the cradle, as shown in
The loading basin 20 also includes an angled member 25, as shown in
A lift mechanism 30 can be used to rotate the cradle 22 to lift the removable bin 26 from its lowered loading position (

The feed chute 40 is shown with more detail in
As can be seen, the feed chute also narrows from the inlet end to the outlet opening(s) so that the plurality of deposit containers being dumped into the inlet end 44 from the loading basin are merged into one or more rows of deposit containers by the time they exit through the outlet openings 48,49 (see

Because the deposit containers leaving the outlet opening 48,49 of the feed chute 40 can sometimes be angled sideways, bunched together or stacked on top of each other, the choke opening 66 operates to restrict and order the row of the deposit containers into a single file, one-at-a-time row of deposit containers having the long axis of each deposit container aligned with the longitudinal axis 56 of the feed channel 50,51. Moreover, as the misaligned deposit containers can tend to pile up against choke plate 64 and clog the feed channel 50,51 during counting operations, manual clearing of the clog may be required by the operator. Manual clearing of the clogs can be accomplished easily and safely as the counting apparatus operates entirely under the influence of gravity and there are no moving machinery or powered parts. Additional side plates 65 can be attached to the sidewalls of the feed channels 50,51 upstream of the choke opening 66 to extend the height of the sidewalls and prevent the deposit containers from spilling over the sides of the feed channels when a clog does occur.
Referring back to
The reduced steepness of the second downward slope 72 serves to slow down and stabilize the flow of deposit containers and to keep them from becoming airborne at the transition channel portion 74,75 described below. In addition, when there are a large number of deposit containers traveling down the feed channel at the same time, the reduction in slope at the middle channel portions 70,71 can cause the deposit containers to contact each other end-to-end, thereby slowing any faster-traveling deposit containers down to the speed of the other deposit containers.
Thus, as the row of deposit containers approaches the final portion of the feed channel, namely the transition channel portions 74,75 and the lower channel portions 80,81, the deposit containers will have been merged into a one or more rows of deposit containers in the feed chute 40, ordered into single file and aligned in with the longitudinal axis of the feed channels 50,51 at the choke openings 66 of the upper channel portion 60,61, and then slowed in the middle channel portions 70,71 to ensure that the deposit containers do not enter the transition channel portions 74,75 with too great a velocity. When there is a large group of deposit containers traveling through the feed channel at the same time, moreover, the deposit containers are abutted end-to-end in the middle channel portions 70,71 so that each container approaches the transition channel portions 74,75 at approximately the same speed.

As can be seen in
It is thought that each deposit container is accelerated by the force of gravity as it passes over the downward, long-radius transition curve 76, which acceleration in turn causes the deposit container to separate from the adjacent deposit container which is immediately behind (e.g. above) the deposit container (e.g. lower) undergoing the acceleration. As the lower deposit container continues to move down the steeper slope 82 of the lower channel portion 80 the separation between the two objects will continue to grow, even though the upper deposit container by this time is also passing over the transition curve 76. Consequently, this separation or “singulation” created by the long-radius transition curve 76 can allow for the lower container to pass through the sensor assembly 84 having a sufficient separation from the next adjacent deposit container to ensure accurate counts.
The long-radius transition curve 76 provides the added benefit of controlling the alignment and/or orientation of the deposit container as it passes through the transition channel portion 74 of the feed channel 50, causing the flow of deposit containers to be smoother and more in-line with longitudinal axis of the feed channels. Because the downward change in direction is gradual rather than abrupt, the deposit containers will not become airborne and instead will remain in continuous contact with contact surface of the feed channel's bottom panel or liner insert. This continuous contact can ensure that the long axis of the deposit container remains aligned with the longitudinal axis of the feed channel as the deposit container rounds the transition curve 76 and proceeds down the lower channel portion 80 to reach the sensor assembly 84 located at the far end of the lower channel portion 80.
If not for the continuous contact with the contact surface providing guidance, the deposit container could become airborne after passing over the downward bend and skew out-of-alignment, which on occasion could allow one or both ends of the deposit container to contact a side wall of the feed channel and thereby slow the passage of the lower deposit container enough for the following deposit container to catch up. In this event the two deposit containers could enter the sensor assembly without adequate separation, which may cause the counting apparatus to miscount the two separate deposit containers as a single deposit container.
The sensor assembly 84 of the lower channel portion 80 is shown in more detail in
As can be seen in the figure, the orientation of the sensor 85/reflector 87 can be in the vertical plane so as to sense and count any deposit container which passes down the center portion of the feed channel, regardless of its height. Furthermore, and as would be appreciated by one of skill in the art, other types of sensor configurations for sensing the passage of deposit bottles are also possible and may be considered to fall within the spirit and scope of the present invention.
The sensor assembly can also include a visible indication to the user or operator of the counting apparatus as to whether or not the beam of light is currently unobstructed or obstructed, as a check to ensure that the optical sensing components are working correctly. Because of the sensor's vertical installation in the sensor assembly, this indicator light may not be easy to see from the operator's position. Illustrated in
