Italian patent application no. 102020000004228 filed on 28/02/2020 - The invention relates to a wrapping machine with a rotary platform.
- In particular, the invention relates to a wrapping machine to wrap products with at least one band of wrapping material.
- When dealing with the wrapping of products in wrapping material bands, a wrapping machine is known, which comprises a base; a rotary platform, which defines a support surface for at least one product and is mounted on the base so as to rotate around a rotation axis, which is substantially vertical and perpendicular to the support surface; and a plurality of support rollers, which are interposed between the base and the rotary platform and are distributed around the aforesaid rotation axis.
- The wrapping machine further comprises a guide upright, which projects upwards from the base and extends in a vertical direction, which is substantially parallel to the rotation axis of the rotary platform; and a support slide, which is configured to receive and hold a spool of wrapping material and is movable along the guide upright so as to wrap the wrapping material band in a spiral around the products combining the movements of the rotary platform around the rotation axis and the movements of the support slide along the guide upright.
- Since the guide upright is fixed and the rotation speed of the platform cannot exceed a threshold value set by safety standards in force, known wrapping machines of the type described above have a relatively long operating cycle, during which each product is wrapped in the relative wrapping material band, and, as a consequence, a reduced productivity.
- The object of the invention is to provide a wrapping machine with a rotary platform, which does not suffer from the drawbacks discussed above and can be actuated in a straightforward, relatively low-cost manner.
