Definitions
- the present invention is generally directed to the technical field of machines for chemical and/or surface treatment of laminar flexible products, such as leathers, hides, fabrics and yarns, and more specifically relates to a drum structure particularly suitable for the transportation from the place of manufacturing to the place of installation and use.
- drums are essentially constituted by a container with at least one part for inlet of the products to be treated and with at least one part for outlet of the treated products, as well as a series of ducts for admission of the substances useful for the treatment.
- the container is rotatably mounted on a support frame formed by robust metallic profiles, in such a manner as to be rotatably driven by suitable motor means about its axis.
- the rotation axis must have a predetermined height from the ground, in order to allow the free rotation without interaction with the ground and the frame.
- a standard drum suitable for the treatment of product quantities ranging between 800 and 1500 kg, has a diameter of about 3 meters and is raised from the ground of 20 - 80 cm, so that its total height with respect to the ground is comprised between 3,20 m and 3,80 m.
- Such maximum height provides, in addition to remarkable big installation problems in companies having little buildings, also great limitations during transportation.
- the machine has to be lifted and loaded on a suitable i transportation means, for example the flatcar of a lorry or of an articulated truck, which has a per se a height of 90-100 cm from the ground.
- the so loaded transportation means can easily reach a height equal to or higher then 4 m, which is the maximum allowable height for transportation without special authorizations.
- the truck driver has to require and obtain from the public traffic authority a special permission in every country or region in which he transits, and has to overcome a number of bureaucratic problems, additional costs and losses of time.
- the truck driver has to require and obtain from the public traffic authority a special permission in every country or region in which he transits, and has to overcome a number of bureaucratic problems, additional costs and losses of time.
- some national laws require special convoys, with dramatic increases of transportation costs and bureaucratic formalities.
- the drum can be transported without any special authorization or convoy.
- this known solution does not solve the problem of reducing the transportation costs because the container and the frame cannot be transported on one single truck and have to be transported using two trucks or one special transport mean, with consequent higher costs than the traditional solution.
- the general object of the present invention is to overcome the abovementioned drawbacks, by providing a drum structure for treatment of flexible sheet-like products, such as leathers, hides, fabrics and yams, which exhibits high flexibility and cost-effectiveness in use.
- a main object is that of providing a drum structure that allows the temporary reduction of the bulk of the machine during transportation until the installation place.
- a particular object is that of providing a drum structure that achieves the above advantages while keeping its effectiveness and functionality.
- a further object is that of providing a drum structure as above described that involves extremely low additional costs, in such a manner to be advantageous from a mere economical point of view.
- a drum structure for treatment of flexible sheet-like products such as leathers, hides, fabrics and yarns, in accordance with claim 1 , comprising a container having a side wall with predetermined outer diameter and with a longitudinal axis, one pair of substantially planar and mutually faced end walls, a support frame securable to the ground on which said container is rotatably mounted for rotation thereof about its longitudinal axis, said container mounted on said frame having a predetermined maximum height from the ground in normal operating condition, characterized in that it comprises support means which are adjustable in height to move said container from a raised position corresponding to the normal operating position to a lowered position substantially ground contacting in such a way as to reduce the vertical bulk and to simplify transportation of the drum structure. Thanks to this particular embodiment, the drum structure can be easily compacted in order to fit the maximum allowable dimensions for transportation without any special permissions or convoys, while being practical and efficient.
