Abstract
A roll-packing machine (100) is provided with a belt drive mechanism having a closed-loop belt (110). Further, the roll-packing machine (100) is provided with a feed mechanism (130, 140) configured to feed a mattress (10) to the belt (110). The belt drive mechanism is configured to form an inner loop (115) of the belt, to receive the mattress (10) in the inner loop (115), and to roll the mattress (10) by advancing the belt (110) while the mattress (10) is received in the inner loop (115). The inner loop (115) of the belt may thus act as a rolling chamber for the mattress (10).
Claims20
A roll-packing machine for packaging a mattress, the roll-packing machine comprising:
- a belt drive mechanism comprising a closed-loop belt;
- a feed mechanism configured to feed the mattress to the belt;
- a tiltable support structure independent of the feed mechanism,
- wherein the belt drive mechanism is configured to form an inner loop of the belt, to receive the mattress in the inner loop, and to roll the mattress by advancing the belt while the mattress is received in the inner loop,
- wherein the belt drive mechanism comprises a first roller and a second roller, the inner loop being formed between the first roller and the second roller,
- wherein the belt drive mechanism is configured to adjust a size of the inner loop by individually controlling rotation of the first roller and the second roller, and
- wherein the first and second rollers may be separated by tilting the tiltable support structure, resulting in the inner loop being opened, so that a mattress roll formed in the inner loop is released and removed by rolling along the belt above the tiltable support structure.
A method of packaging a mattress using a roll-packing machine, the method comprising:
- feeding the mattress to a closed-loop belt of a belt drive mechanism;
- forming an inner loop of the belt, wherein the belt drive mechanism comprises a first roller and a second roller, the inner loop being formed between the first roller and the second roller;
- receiving the mattress in the inner loop;
- rolling the mattress by advancing the belt while the mattress is received in the inner loop to create a mattress roll;
- adjusting a size of the inner loop with the belt drive mechanism by individually controlling rotation of the first roller and the second roller;
- and
- tilting a tiltable support structure to open the inner loop by moving one of the first and second rollers away from the other of the first and second rollers so that a portion of the belt between the first and second rollers assumes a straight-line form;
- rolling the mattress roll along the belt to eject the mattress roll from the roll-packing machine with the tiltable support structure below the mattress roll.
A method of packaging a mattress using a roll-packing machine, the method comprising:
- feeding the mattress to a closed-loop belt of a belt drive mechanism;
- forming an inner loop of the belt, wherein the belt drive mechanism comprises a first roller and a second roller, the inner loop being formed between the first roller and the second roller;
- receiving the mattress in the inner loop;
- rolling the mattress by advancing the belt while the mattress is received in the inner loop to create a mattress roll;
- adjusting a size of the inner loop with the belt drive mechanism by individually controlling rotation of the first roller and the second roller;
- and
- tilting a support structure from a raised position to a lowered position to open the inner loop by moving one of the first and second rollers away from the other of the first and second rollers, so that said one of the first and second rollers is below the other of the first and second rollers;
- and
- rolling the mattress roll along the belt to eject the mattress roll from the roll-packing machine with the support structure below the mattress roll.
