## Abstract

An apparatus and method for unloading a plurality of items from a carrier is provided. The items are preloaded in the carrier, in a column having a top row. The apparatus has a first conveyor which has a first end for approaching the top row, an opposite second end and a conveyor body connecting the first end and the second end. The first end has an end platform for receiving the top row and an arm associated with the end platform for transporting the top row onto the end platform. A second conveyor is operatively connected to the first conveyor for receiving the top row from the first conveyor and transporting the top row for further processing the top row. The apparatus also has a control unit for controlling the movement of the first conveyor and the second conveyor.

## Claims

### Claim 1

An apparatus for unloading a plurality of items from a carrier, wherein the items are preloaded in a column having a top row, the apparatus comprising:
a first conveyor comprising a first end for approaching the top row, an opposite second end and a conveyor body connecting the first end and the second end;
wherein the first end comprises an end platform for receiving the top row and an arm associated with the end platform for transporting the top row onto the end platform;
a second conveyor operatively connected to the first conveyor, the second conveyor configured to receive the top row from the first conveyor and transport the top row for further processing the top row; and
a control unit configured to control the movement of the first conveyor and the second conveyor.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the arm comprises: a detector for detecting a target design provided on an exposed surface of the top row; and an engaging structure for positively engaging the top row based on the detection of the target design.

### Claim 3 (depends on 2)

The apparatus according to claim 2, wherein the engaging structure of the arm comprises one or more vacuum heads.

### Claim 4 (depends on 2)

The apparatus according to claim 2, wherein the control unit is configured to move the engaging structure of the arm based on the detection of the target design.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein the control unit is configured to move the end platform of the first conveyor substantially vertically and horizontally.

### Claim 6 (depends on 5)

The apparatus according to claim 5, wherein the control unit is configured to move the end platform of the first conveyor substantially vertically based on a height of the items.

### Claim 7 (depends on 1)

The apparatus according to claim 1, wherein the control unit is configured to move the second conveyor substantially horizontally.

### Claim 8

A method for unloading a plurality of items from a carrier, wherein the items are preloaded in a column having a top row, the method comprising:
moving an end platform of a first conveyor to approach the top row within the carrier;
moving an arm associated with the end platform to face an exposed surface of the top row, on which surface a preprinted target design is provided;
detecting the preprinted target design and positively engaging the top row based on the detection;
transporting the engaged top row onto the end platform of the first conveyor;
transporting the top row from the first conveyor onto a second conveyor;
transporting the top row from the second conveyor for further processing the top row; and
moving the end platform of the first conveyor downwardly a predetermined distance.

### Claim 9 (depends on 8)

The method according to claim 8, wherein the first conveyor is stopped prior to transporting the engaged top row onto the end platform of the first conveyor and is restarted after transporting the engaged top row onto the end platform of the first conveyor.

### Claim 10 (depends on 8)

The method according to claim 8, wherein in the step of moving the end platform of the first conveyor downwardly the predetermined distance, the predetermined distance is calculated based on a height of the items.
