Definitions
- the present invention relates to a machine for continuous treatment of fabrics, for example for drying treatment, above all for treating cord fabrics.
- the present invention relates to a machine of the type comprising a combination of: a path of travel for the fabric to be treated; a device to feed the fabric and a device to remove the fabric; along said path of travel a plurality of rotating drums inclined in relation to the horizontal, through which said fabric is made to travel to be subjected to a continuous treatment process; and between adjacent drums means to transfer the fabric from a drum upstream to a drum downstream.
- a machine for continuous treatment of fabric of the type mentioned above comprising a plurality of drums in series along the path of travel of the fabric in the Italian patent application n. PR99A00002, filed on 12.1.1999.
- the present invention relates to improvements to a machine of the type mentioned above in order to optimize the characteristics and solve some technical problems.
- an object of the present invention is to produce a machine of the type mentioned, in which transfer of the fabric from one drum to the other is more simple and efficient.
- the same inventive concept may be applied to machines for discontinuous treatment, that is in which a bolt of fabric is closed in a ring joining the two ends of the bolt and is made to circulate along a closed path of travel for a certain period of time, after which the bolt is opened again and removed from the machine.
- a machine comprising: a path of travel for the fabric to be treated; along said path of travel a plurality of rotating drums, inclined in relation to the horizontal, through which said fabric is made to travel to be subjected to a treatment process, each rotating drum having an inlet and an outlet; and, between adjacent drums, means to transfer the fabric from a drum upstream to drum downstream, characterized in that consecutive drums are positioned so that the outlet of the upstream drum, in relation to the direction of travel of the fabric, js . side _byINside with the inlet of the drum downstream.
- the . fabric, closed in a ring is made to circulate along a path of travel which successively and repeatedly travels through two or more drums positioned along this path of travel, rather than be fed and removed continuously in an open path of travel.
- transfer of the fabric may be performed entirely or partly pneumatically, by means of a flow of air inside a duct, preferably although not necessarily with a closed cross section.
- a flow of air inside a duct preferably although not necessarily with a closed cross section.
- the object of an enhanced embodiment of the present invention is to further improve the efficiency of the machine, overcoming the drawbacks of the prior art machine from this viewpoint.
- the pneumatic duct to transport the fabric from one drum to the successive one is made to lead into the inside of the drum through the inlet for the fabric.
- the air used for transport enters the drum.
- this conditioned air is further utilized to treat the fabric also in the drum, contrary to what happens in the prior art machine, in which the air is substantially dispersed at the duct outlet. This saves energy and improves the quality of treatment.

- Fig.4 a plan view, of a machine according to the invention in a second_ embodiment.
- the machine has an inlet 1 for continuously feeding a fabric T, by means of a feed device 1 , constituted in the example shown by a reel.
- the fabric T is made to travel through a series of machine sections, indicated with 2A, 2B, 2C, 2D, each of which comprises a respective rotating drum 3A-3D.
- the sections 2A-2D and the rotating drums are positioned along a feed path of the fabric.
- four sections are provided with four respective drums substantially the same as one another, positioned side by side.
- One of the sections and more specifically section 2A with the drum 3A is shown in greater detail in Figs. 2 and 3 and will be described hereunder.
- the number of sections and drums may vary according to the complexity and dimension of the machine.
- the fabric T which has travelled through the various sections 2A-2D and therefore the various drums 3A-3D in sequence, is removed from the machine by a removal device generically indicated with 5 and constituted (in the example shown) by a further reel.
- the fabric T is subjected to mechanical and, where required, heat treatment, of a type substantially per se known and similar to the treatment described in the aforesaid patent application PR99A00002.
- the rotating drum 3A is positioned with its axis
- the cord fabric T is fed inside the drum 3A by transfer means 6 which comprise, in the example shown, a reel 7 motorized by a motor only shown schematically in Fig.2 and marked therein with 7M.
- transfer means 6 are provided with a duct 9 inside which, through an annular distributor 9A or equivalent means, a flow of air is fed which comes from a blower and if necessary a heating battery, not shown.
- 9A forms an ejector for drawing the fabric.
- the air blown into the duct 9 draws the fabric T mechanically fed by the reel 7 or in any case facilitates its running along the duct 9 until it reaches the inside of the rotating drum 3A.
- the duct 9 has a curvilinear form and leads into the drum 3A through an inlet 11 in the drum, positioned on the side of the section 2A in which the transfer means 6 are positioned.
- the inlet 11 of the drum 3A is located at the highest end of the drum 3A, which is equipped, at the opposite and lower end, with an outlet 12, through which the fabric T is delivered from the rotating drum 3Ato drop into a collection tub 13. From this collection tub 13 the fabric is picked up by the reel 7 of the subsequent section 2B to be fed into the rotating drum 3B.
- a similar device is provided in sections 2B, 2C. As can be seen in Fig. 1 , in the last section 2D of the machine, vice versa, the fabric is taken from the respective tub 13 by a reel 7B which transfers the fabric to the removal device 5.
- the drum 3A (and similarly the other drums 3B-3D) are supported at the highest end by means of a hinge with horizontal axis 15, in the plan projection the axis of the hinge is at 90° in relation to the axis A-A of the drum 3A.
- the drum 3A is hung on a pair of rods 17A, 17B approximately vertical, each of which is connected, by a joint 19A, 19B to an actuator 21 A, 21 B.
- the actuator 21 A, 21 B is represented in the form of a mechanical jack, but may also be a piston-cylinder actuator or any other type of suitable mechanism.
- the rods 17A, 17B may be replaced by other mechanical parts, for example by chains or cables. In this case the actuators 21 A, 21 B may be constituted by respective winches or even by a single winch.
- each rod 17A, 17B is hinged in 23A, 23B to a supporting frame 25 of the rotating drum 3A.
- this layout inclination of the axis A-A of the rotating drum 3A may be modified by adjusting the rods 17A, 17B by means of the actuators 21 A, 21 B for the purposes described in greater detail hereunder.
- the supporting frame 25 of the rotating drum 3A has a shaft 27 parallel to the axis A-A of the rotating drum 3A, keyed on which are two toothed wheels 28 meshing with corresponding toothed ring gears 29 integral with the drum 3A.
- the drum also rests on the frame 25 by means of rollers or wheels not shown, substantially in the same manner described in the Italian patent application PR99A00002.
- friction wheels may be used, with surfaces in material suitable to transmit motion by simple friction.
- the ring gears may be omitted.
- rotating movement may be provided with any suitable means.
- the shaft 27 receives rotating movement from a motor shaft 31 controlled by a motor 33 (Fig.
- the universal joint 35 is substantially in line with the axis 15 of oscillation of the drum 3A, so that inclination of the drum 3A can be varied without this being prevented by the mechanical transmission between the motor 33 and the drum 3A.
- the motor 33 makes the drum 3A rotate around its axis A-A.
- the rotating movement may be a continuous, intermittent or alternate rotating movement, or a combination of these movements, according to the requirements of the work cycle and according to the settings made by the operator on a specific control unit, indicated schematically with 37 (Fig. 2).
- Other systems to transmit rotating motion to the drums may be used, as only their suitability to allow inclination of the drum to be modified is relevant.
- the tub 13 is resting in an tilting manner on the supporting frame 25 of the drum 3A, so that it can oscillate around an axis 39 parallel to the axis 15 of oscillation of the drum 3A.
- the tub is attached to a tie rod 41 , the top end of which is connected to a bracket 43 integral with the fixed frame 45 of the machine, to which the actuators 21 A, 21 B are also connected.
- a sensor for example a load cell 47, is interposed between the bracket 43 and the tie rod 41 , to detect the tractive force applied to the tie rod 41 , due to the weight of the fabric in the tub 13, for the purposes described below in greater detail.
- the load cell 47 is interfaced with the control unit 37 just as the actuators 21 A, 21 B are interfaced with it.
- the tie rod 41 , the relative bracket 43 and the load cell 47 may be double, just as the rods 17A, 17B for the drum 3A, although this is not absolutely necessary as the tub has a smaller mass than the drum 3A.
- the feeding device 1 of the fabric T By means of the feeding device 1 of the fabric T, the latter is fed to the reel 7 of the section 2A and through of the duct 9 it is fed into the drum 3A.
- the fabric T moves gradually along the drum 3A, thanks to its inclination on the horizontal and is delivered through the outlet 12 into the tub 13 of section 2A. From here the fabric is picked up by the reel 7 of the successive section 2B where the fabric is subjected to similar treatment in the drum 3B and so on until it is unloaded into the tub 13 of section 2D, from which the completely treated fabric T is removed by the reels 7B and 5.
- each reel 7, of the feeding device 1 and of the removal device 5 must be controlled in order to obtain gradual advance of the fabric through the various drums and to prevent excessive accumulation of fabric in each tub 13.
- the quantity of fabric (in weight) accumulated in each tub 13 is detected by the load cells 47.
- the control unit 37 controls the speed of the reels 7.
- the inclination of each drum may be individually registered by means of the respective actuators 21 A, 21 B, which raise or lower the rods 17A, 17B according to the double arrow F17 (Figs. 2 and 3).
- a load cell or a pair of load cells may be provided (in addition to or to replace the load cell 47) associated with the rods 17A, 17B, for example positioned in the joints 19A, 19B, and indicated with 48.
- This information can be used directly, alone or in combination with information from the load cell 47, to control the actuators 21 A, 21 B and hence to modify inclination of the drum. For example, if an excessive quantity of fabric is detected in the drum, inclination of the drum can be increased to increase the speed with which the fabric T is unloaded from the drum.
- Fig. 4 shows a second embodiment in a schematic plan view. In this case each section 2A-2C (three in the example) is aligned according to a rectilinear layout.
