Description

MACHINE FOR DRYING AND TREATING FABRICS WITH ROTATING DRUM AND FABRIC TRANSFER DUCTS}

As a continuous processing apparatus of this type of fabric, in Italian patent application PR99A00002 filed on December 1, 1999, there is a configuration in which a plurality of drums are arranged in series along a conveyance path of the fabric.

The present invention relates to an improvement of this type of device for optimizing the characteristics of this type of device while at the same time solving the problems of the prior art.

In particular, it is an object of the present invention to provide an apparatus of this type which is more convenient and effective in conveying from one drum to another drum.

The present invention relates, for example, to a continuous processing apparatus for fabrics, in particular for drying fabrics on cord fabrics.

More specifically, the present invention, the transfer path for the fabric to be treated; Fabric feeding device and fabric removing device; A plurality of rotating drums having an inlet and an outlet along which the fabric is inclined with respect to the horizontal direction, through which the fabric passes; It relates to an apparatus of the type provided with conveying means for transferring fabric from an upstream drum to a downstream drum between adjacent drums.

2 is a cross-sectional view taken along II-II of FIG.

3 is a cross-sectional view taken along line III-III of FIG.

4 is a plan view of a processing apparatus according to a second embodiment of the present invention.

The above and other objects and advantages, which will be apparent to those skilled in the art by reading the following detailed description, are, in fact, positioned continuously so that the outlet of the upstream drum is arranged side by side with the inlet of the downstream drum (relative to the conveying direction of the fabric). It is achieved by an apparatus of this type characterized in that it is determined. In this way, when the fabric is transferred from the unloading area of one drum to the loading drum of the subsequent drum, the conveyance path of the fabric through the device is substantially reduced, so that the transfer efficiency of the fabric between one drum and the next drum is reduced. This is improved.

The concept of this invention is that the device for discontinuous processing, i.e., the bolt of the fabric is opened again and removed from the device, and then closed in a ring joining both ends of the bolt, so that the bolt is closed for a predetermined time. It is also applicable to a device circulating along. In this case, according to the present invention, the transfer path for the fabric to be treated; A plurality of rotating drums having an inlet and an outlet along which the fabric is inclined with respect to the horizontal direction, through which the fabric passes; An apparatus having a conveying means for conveying a fabric from an upstream drum to a downstream drum between adjacent drums, wherein the outlet of the upstream drum is arranged side by side with the inlet of the downstream drum in relation to the conveying direction of the fabric. A drum is characterized in that it is positioned continuously. In this case, the fabric closed in the ring is to be circulated along a transport path that continues to run repeatedly over two or more drums located along the transport path, rather than being continuously fed and removed in the open transport path. .

Advantageously, the conveyance of the fabric may be carried out pneumatically, in whole or in part, by means of air flow means in the tube, even if it does not necessarily have a closed cross section. Itself is known from PR99A00002.

Nevertheless, in the conventional apparatus, air flow is not improved, causing a certain amount of energy loss in addition to the undesirable increase in adhesion of the fabric.

An object of a preferred embodiment of the present invention is to further improve the efficiency of the apparatus in order to overcome the drawbacks of the conventional apparatus from the above point of view. For this purpose, an air tube for conveying the fabric from one drum to the next is adapted to pass through the inlet of the drum through the inlet for the fabric of the drum. In this way, the air used for conveyance flows into a drum. By this, the conditions of temperature and humidity are usually controlled so as to act thermally on the fabric being transported. By allowing the tube to pass through the drum, this controlled air is further used to process the fabric even in the drum, as opposed to conventional devices where air is actually dispersed to the outlet of the tube. This saves energy and improves the amount of processing.

Further advantageous features of this device according to the invention are described below with reference to examples of embodiments, which are also shown in the appended claims.

The present invention may be better understood by reading the following description with reference to the accompanying drawings, in which the accompanying drawings represent actual, non-limiting embodiments of the invention.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described in detail.

Referring first to FIGS. 1 to 3, the treatment apparatus of the present invention has an inlet 1 for continuously feeding the fabric T by a feeder 1 consisting of a reel in the illustrated example. The fabric T is conveyed through a series of device portions 2A, 2B, 2C, and 2D provided with respective rotating drums 3A to 3D. The device sections 2A to 2D and the rotating drum are positioned along the supply path of the fabric. In the example shown, four respective rotating drums are arranged approximately side by side with respect to each other. One of the device parts, more specifically, the device part 2A with the drum 3A, is shown in more detail in FIGS. 2 and 3, which will be described later. The number of each device portion and drums can vary depending on the complexity and dimensions of the device.

The fabric T sequentially transferred through the various device sections 2A to 2D, and thus through the various rotating drums 3A to 3D, is another reel (in the illustrated example) represented by (5) as a whole. It is removed from the processing device by the configured removal device. In each of the drums 3A to 3D, the fabric T is conveyed through the drum along the supply path, while being similar to the treatment disclosed in the above-mentioned patent application PR99A00002, and in actual mechanical processing in a form known as it is, Heat treatment is performed as needed.

2 and 3, in the apparatus section 2A (the same applies to the remaining apparatus sections 2B, 2C, and 2D), the axis 3 of the rotating drum 3A is horizontal. It is inclined with respect to the direction, for example, about 5 to 20 degrees, preferably about 5 to 15 degrees (but not limited to these values). The cord fabric T is fed into the drum 3A by means of a conveying means 6 consisting of a reel 7 driven by a motor 7M schematically shown in FIG. 2 only in the illustrated example. In addition to the reel 7, the conveying means 6 is provided with a flow of air from a blower inside it, or a heating cell not shown, as necessary, via an annular distributor 9A or equivalent means. The pipe 9 to be supplied is provided. In practice, the accessories 9, 9A form an ejector that draws in the fabric. The air blown into the tube 9 draws the fabric T mechanically supplied by the reel 7, or optionally along the tube 9 until it reaches the interior of the rotating drum 3A. To facilitate its flow. In the illustrated example, the tube 9 has a curved shape and is fed into the drum 3A through the inlet 11 in the drum 3A located on the side of the device portion 2A where the conveying means 6 is positioned. Will lead to.

The inlet 11 of the drum 3A is located at the highest end of the drum 3A, and at the lower end opposite it, an outlet 12 is located, through which the fabric T is rotated. Is discharged into the recovery container (13). From this collection container 13, the fabric is picked up by the reel 7 of the subsequent device section 2B and fed into the rotating drum 3B. Similarly, a device (here, a supply device, a removal device, etc.) is provided. It is also provided in the parts 2B and 2C. As can be seen in FIG. 1, in the last device part 2D of the device, or in the reverse device part, the fabrics are respectively reeled by a reel 7B for transferring the fabric to the removal device 5. It is taken from the barrel 13 of.

The drum 3A (the same applies to the other drums 3B to 3D) is supported at the top end by a hinge having a horizontal axis 15. In the plan view, the axis of the hinge is the axis of the drum 3A. It is 90 ° to (AA). The drum 3A is suspended on a pair of substantially vertical rods 17A, 17B at the opposite lower end, and each of these rods is actuated by joints 19A, 19B. It is connected to (21A) and (21B). The actuators 21A, 21B are represented in the form of mechanical jacks, but may be piston-cylinder actuators or other types of suitable instruments. Similarly, other mechanical parts such as chains and cables may be used instead of the bars 17A and 17B. In this case, the actuators 21A and 21B may be composed of one winch at each winch or wick.

Each rod 17A, 17B is hinged at 23A, 23B with respect to the support frame 25 of the rotating drum 3A at the opposite end with respect to the seam 19A, 19B. It is. According to this configuration, the inclination of the axes A-A of the rotating drum 3A may be changed by adjusting the rods 17A and 17B by the actuators 21A and 21B to be described in more detail below.

The support frame 25 of the rotating drum 3A has a shaft 27 parallel to the axis AA of the rotating drum 3A, and on this shaft is integral with the drum 3A. Two corresponding toothed wheels 28 engaged with the toothed ring gear 29 are fixed. The drum is placed on the frame 25 by rollers or wheels not shown in the same manner as the method described in the above-described Italian Patent Application No. PR99A00002. Alternatively, the toothed wheel may be a friction wheel having a surface of a material suitable for transmitting movement by simple friction. In this case, the ring gear may be omitted. In general, the rotary motion may be provided by any suitable means. The shaft 27 receives a rotational movement from the motor shaft 31 controlled by the motor 33 (see FIG. 2) through the universal joint 35 interposed between the shaft 27 and 31. . Since the universal joint 35 is approximately in line with the axis 15 of the vibration of the drum 3A, the inclination of the drum 3A is prevented by the mechanical transmission between the motor 33 and the drum 3A. You can change it without a problem.

The drum 3A is rotated about its axis A-A by the motor 33. This rotational movement may be continuous, intermittent or alternating rotational movements, or a combination of these movements, depending on the requirements of the work cycle and also depending on the operator's settings for the dedicated control unit (see FIG. 2), schematically indicated at 37. do. It is also possible to use other systems that transmit rotational motion to the drum, provided that their suitability is justified so that the drum can be tilted.

The mechanical parts associated with the support of the drum and their rotation are almost similar to those for the other device parts and are therefore omitted in the top view of FIG. 1 to simplify the drawing.

Since the cylinder 13 is inclined on the support frame 25 of the drum 3A, it can vibrate about the axis 39 parallel to the oscillation axis 15 of the drum 3A. The barrel 13 is attached to a tie rod 41 at the opposite end in relation to being placed on the frame 25, the leading end of which is fixed frame 45 of the processing apparatus. And an actuator 21A, 21B are also connected to this fixed frame. A sensor, for example a load cell 47, is inserted between the bracket 43 and the tie rod 41 and applied to the tie rod 41 due to the weight of the fabric in the bin 13. The traction is detected (more on this later).

The load cell 47 is in contact with the control unit 37 as soon as the actuators 21A and 21B contact the control unit 37.

The tie rod 41, the bracket 43 and the load cell 47 associated therewith may be two like the rods 17A and 17B for the drum 3A, but this is smaller than the drum 3A. It is not absolutely necessary as it has mass.

The configuration of the device portion 2A described with reference to FIGS. 2 and 3 is the same for the remaining device portions 2B, 2B, and 2D. It is interposed between the actuator of the device unit and the sensor.

The operation of the processing apparatus described above is as follows.

By the feeding device 1 of the cloth T, the cloth is supplied to the reel 7 of the device portion 2A and supplied into the drum 3A through the pipe 9. Here, the fabric is subjected to mechanical treatment through the continuous or alternating rotational movement of the drum, and the inside of the drum may have a suitable ribbing or similar form. The fabric T moves gradually due to the inclination of the corresponding drum in the horizontal direction along the drum 3A, and is discharged through the outlet 12 into the barrel 13 of the apparatus portion 2A. From here, the fabric is picked up by the reel 7 of the subsequent apparatus section 2B until finally discharged into the cylinder 13 of the apparatus section 2D, and even in the apparatus section, the drum 3B. ), The fabric T, which has been completely processed from the apparatus portion 2D, is removed by the reels 7B and 5, for example.

The reel speed of the reel of the feeder 1 and the reel of the remover 5 can be controlled to obtain gradual advancement of the fabric through the various drums and to prevent excess accumulation of the fabric in each bin 13. There is a need. For this purpose, the load cell 47 detects the amount (weight) of the fabric accumulated in each bin 13. Based on this information, the control unit 37 controls the speed of the reel 7. In addition, when it is necessary to change the discharge speed of the fabric T from each of the drums 3A, 3B, 3C, and 3D, the inclination of each drum is changed according to the bidirectional arrow f17. You may record separately by each actuator 21A, 21B which raises and lowers 17A) and 17B (refer FIG. 2 and FIG. 3). By increasing the inclination of the axes A-A of the drums 3A to 3B with respect to the horizontal direction, the speed at which the fabric is discharged into the barrel 13 is increased. In addition, if the inclination angle in the horizontal direction is reduced, the discharge speed is reduced in contrast to the above.

According to a modified embodiment of the present invention, one load cell or a pair of load cells indicated by (48) is, for example, the rods 17A and 17B positioned at the joints 19A and 19B. It may be provided in connection (in addition to or instead of the load cell 27). In this way, it is possible to detect the load on the rods 17A and 17B which is proportional to the weight of the fabric T, and thus the amount of the fabric, obtained from the drum at that moment. This information is used to control the actuators 21A and 21B directly, alone or in combination with information from the load cell 47, so that the inclination of the drum can be changed. For example, if excess amount of fabric is detected in the drum, the inclination of the drum may be increased to increase the rate at which the fabric T is ejected from the drum. By increasing the speed of the reel 7 on the downstream side of the drum, it is possible to prevent excessive accumulation of fabric in the bin 13. Alternatively, the speed of the reel 7 is relative to the signal input from the load cell 47 (when provided in combination) instead of directly interlocking with the signals from the load cells associated with the rods 17A and 17B. You may make it work. The signals input from the tie rods 41 and / or the load cells on the rods 17A, 17B are also within each tube 9 as a function of the feed rate of the fabric T from one device part to the other device part. You may use it to adjust the flowing air by the control part 37. FIG.

4 is a schematic plan view of a second embodiment of the present invention. In this case, each apparatus part 2A- (2C) (three in this example) is aligned according to the linear structure. The configuration and operation of the means for controlling the inclination of the drum of each device section are the same as described above.

The drawings of the present invention merely exemplify non-limiting examples of the embodiments of the present invention, and the embodiments and configurations thereof may be changed without departing from the scope of the basic idea of the present application. Reference numerals in the appended claims are provided merely for the purpose of facilitating reading in light of the foregoing description and the accompanying drawings, and do not limit the scope of protection.

As mentioned above, according to this invention, it is possible to provide the drying processing apparatus of the textile which improved the efficiency by overcoming the fault of the conventional apparatus. Moreover, according to the apparatus of the preferred embodiment of the present invention, energy is saved and the amount of processing is improved.
