Abstract

Claims (38)

1. An ice bagging apparatus comprising:

a) a frame,

b) a first ice collecting zone within said frame comprising a collecting bin;

c) an ice bagging zone within said frame comprising

i) a film feeding mechanism for conveying two superposed heat-sealable elongated film webs of plastic from a film web stock according to a conveying direction, and

ii) a welding apparatus for joining said two film webs to form a bag,

d) a first ice transport system within said frame, having an inlet opening in the first ice collecting zone and an outlet opening in the ice bagging zone and positioned between the two film webs above the formed bag,

e) a measuring arrangement within said frame for measuring the amount of ice dispensed into the bag by the first ice transport system,

wherein the film feeding mechanism comprises a pair of rollers between which the film webs are passed, means for pressing the rollers against each other for retaining the film webs there between, and a film feeding motor operationally connected to at least one of the rollers, and

wherein the measuring arrangement comprises a weighing scale which includes a base and a weighing pan, wherein the base is attached to the frame, and wherein the pair of rollers are suspended from the weighing pan.

2. An ice bagging apparatus according to claim 1 , wherein the first ice transport system comprise a chute, a drive spring positioned inside said chute along the axis thereof, and an drive spring drive motor.

3. An ice bagging apparatus according to claim 2 , wherein the drive spring is a helical spring.

4. An ice bagging apparatus according to claim 2 , wherein at least one drain opening is formed at substantially the lowest position of the chute, and wherein a drip pan is provided underneath said at least one drain opening.

5. An ice bagging apparatus according to claim 1 , wherein the welding apparatus comprise means for performing thermal sealing, the means being disposed at a position after the rollers as seen in the conveying direction of the film webs.

6. An ice bagging apparatus according to claim 1 , wherein the welding apparatus comprises means of thermal sealing on the film webs both in direction across and along the conveying direction.

7. An ice bagging apparatus according to claim 1 , wherein the welding apparatus comprises means for separating the ice filled bag from the film webs.

8. An ice bagging apparatus according to claim 1 , wherein the measuring arrangement comprise a strain gauge scale which is interconnected between the frame and the pair of rollers.

9. An ice bagging apparatus according to claim 1 , wherein the first ice transport system is a downwardly directional ice transport system.

10. An ice bagging apparatus comprising:

a) a first ice collecting zone comprising a first collecting bin;

b) a second ice collecting zone comprising a second collecting bin;

c) an ice bagging zone comprising

i) a film feeding mechanism for conveying two superposed heat-sealable elongated webs of film from a film stock according to a conveying direction, and

ii) a welding apparatus for joining said two film webs to form a bag,

d) a first ice transport system, having an inlet opening in the first ice collecting zone and an outlet opening in the ice bagging zone and positioned between the two webs of film above the formed bag,

e) a second ice transport system, having an inlet opening in the second ice collecting zone and an outlet opening in first collection zone, and

f) a measuring arrangement for measuring the amount of ice dispensed into the bag by the first ice transport system,

wherein the film feeding mechanism comprises a pair of rollers between which the film webs are passed, means for pressing the rollers against each other for retaining the film webs there between, and film feeding motor operationally connected to at least one of the rollers, and

wherein the measuring arrangement comprises a weighing scale which includes a base and a weighing pan, wherein the base is attached to the frame, and wherein the pair of rollers are suspended from the weighing pan.

11. An ice bagging apparatus according to claim 10 , wherein the first and/or second ice transport system comprise a chute, a drive spring positioned inside said chute along the axis thereof, and an drive spring drive motor.

12. An ice bagging apparatus according to claim 11 , wherein the drive spring is a helical spring.

13. An ice bagging apparatus according to claim 11 , wherein at least one drain opening is formed at substantially the lowest position of the chute, and wherein a drip pan is provided underneath said at least one opening.

14. An ice bagging apparatus according to claim 10 , wherein the welding apparatus comprise means for performing thermal sealing, the means being disposed at a position after the rollers as seen in the conveying direction of the film webs.

15. An ice bagging apparatus according to claim 10 , wherein the welding apparatus comprises means of thermal sealing on the film webs both in direction across and along the conveying direction.

16. An ice bagging apparatus according to claim 10 , wherein the welding apparatus comprises means for separating the ice filled bag from the film webs.

17. An ice bagging apparatus according to claim 10 , wherein the measuring arrangement comprise a strain gauge scale which is interconnected between the frame and the pair of rollers.

18. An ice bagging apparatus according to claim 10 , wherein the first ice transport system is a downwardly directional ice transport system.

19. An ice bagging apparatus according to claim 10 , wherein the second ice transport system is an upwardly directional ice transport system.
