Tray system and method for filling pills into blister packs
A tray system for filling pills into a blister pack is provided, as well as a corresponding method. The system includes a mounting tray to support the blister pack, rows of lights, with each light adapted to illuminate the pill-chambers of the blister pack; a depositing plate placed over the mounting tray and includes depositing-plate rows with pairs of pill-drop surface and a pill-hole, each pill-hole faces a corresponding pill-chamber; a sliding tray placed over the depositing plate which includes sliding-tray rows with opened cavities, and is slidable over the depositing plate from a pill-drop position to a chamber-filling position. Moving the sliding tray from the pill-drop position to the chamber-filling position pushes the pills from the pill-drop surfaces to the pill-chambers. The depositing plate material allows lights emissions to pass through the pill-drop surfaces while hiding the pills in the pill-chambers of the blister pack.
1. A tray system for filling pills into a blister pack, the blister pack being provided with rows of pill-chambers, the tray system comprising:
a mounting tray provided with rows of recesses, the mounting tray being shaped and configured to support the blister pack thereon, the pill-chambers fitting in corresponding recesses of the mounting tray;
rows of lights, each light facing one of the recesses of the mounting tray and being adapted to be turned on to illuminate the corresponding pill-chambers of the blister pack in which pills are to be dropped;
a depositing plate placed over the mounting tray, the depositing plate comprising depositing-plate rows facing the rows of the mounting tray, each depositing-plate row comprising side-by-side pairs of pill-drop surface and a pill-hole, the pill-hole of each pair facing a corresponding pill-chamber of the blister pack;
a sliding tray placed over the depositing plate, the sliding tray comprising sliding-tray rows providing with opened cavities, the sliding tray being slidable over the depositing plate from a pill-drop position to a chamber-filling position, wherein:
in the pill-drop position, the opened cavities are facing the pill-drop surfaces, such that pills can be dropped onto the pill-drop surfaces, and
in the chamber-filling position, the opened cavities are facing the pill-holes, such that pills can be dropped into the pill-chambers of the blister pack;
whereby moving the sliding tray from the pill-drop position to the chamber-filling position pushes the pills from the pill-drop surfaces to the pill-chambers of the blister pack;
the depositing plate being made of a material allowing light emissions from the lights to pass through the pill-drop surfaces while hiding the pills in the pill-chambers of the blister pack, when the sliding tray is in the pill-drop position, allowing a user to see a diffused light corresponding to the pill-chambers of the blister pack into which the pills are to be dropped and allowing a camera to detect pills on the pill-drop surface of the depositing plate, while hiding the pills already in the pill-chambers of the blister pack.
2. The tray system according to claim 1 , wherein each recess has a greater area than an area of the pill-holes of the depositing plates.
3. The tray system according to claim 1 , wherein the depositing plate material comprises a blurring element, the blurring element being adapted to allow the diffused light to pass therethrough while dimming the view of the pills in the pill-chambers of the blister pack.
4. The tray system according to claim 3 , wherein the blurring element is a textured surface composed of a plurality of prismatic shapes.
5. The tray system according to claim 3 , wherein the blurring element is a frosted surface treatment applied to the surface of the depositing plate.
6. The tray system according to claim 5 , wherein the frosted surface treatment is sanding the surface of the depositing plate.
7. The tray system according to claim 5 , wherein the frosted surface treatment is a translucent layer of paint applied on the surface of the depositing plate.
8. The tray system according to claim 5 , wherein the frosted surface treatment is a frosted film applied onto the surface of the depositing plate.
9. The tray system according to claim 3 , wherein the blurring element of the depositing plate is caused by the translucency of the depositing plate material.
10. The tray system according to claim 9 , wherein translucency of the depositing plate material is between 25% and 75%, where 0% is completely opaque and 100% is completely transparent.
11. The tray system according to any one of claim 1 , wherein the sliding tray material is the same as the depositing plate material.
12. The tray system according to any one of claim 1 , wherein the sliding tray and the depositing plate form a sliding tray assembly and are linked together such that the sliding tray moves in parallel to the depositing plate when transitioning between the pill-drop position and the chamber-filling position.
13. The tray system according to claim 12 , further comprises a guiding element provided on one of the sliding tray and the depositing plate and moving along a corresponding receiving element provided on the other one of the sliding tray and the depositing plate, maintaining the sliding tray parallel to the depositing plate during transition between the pill-drop position and the chamber-filling position.
14. The tray system according to any one of claim 1 , further comprising a light board positioned underneath the mounting tray, the light board being provided with the rows of lights.
15. The tray system according to any one of claim 1 , further comprising a microcontroller and a wireless communication module, to wirelessly control the lights facing the recesses of the mounting tray.
16. The tray system according to claim 15 , wherein the wireless communication module is a Bluetooth device.
17. The tray system according to claim 15 , further comprising a status device having status lights for indicating a status of the wireless communication module.
