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).
Claims23
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 supply roll of wrapping material;
- a tool for cutting the wrapping material;
- 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 and one or more layers of the wrapping material by advancing the belt while the mattress and one or more layers of the wrapping material are 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, resulting in the inner loop being opened, so that a mattress roll formed and wrapped in the inner loop is released and removed.
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 and wherein the roll-packing machine is further configured to wrap the rolled mattress by:
- feeding a wrapping material into the inner loop with the rolled mattress;
- and
- advancing the belt to rotate the rolled mattress in the inner loop and wrap the wrapping material around the rolled mattress.
