Definitions
- the invention refers to improvements and modifications in the polychromatic printing systems of yarn on distaffs.
- the machine carries out in synchronism and automatically, with continuous cycle, the subsequent polychromatic printing operations, the colour fixing, washing and extraction of the most part of water present in the distaffs with yarns of any type of fibres whatever.
- the invention device enables to avoid the present differentiated working compartments by adopting a machine which carries out the complete operating cycle of the polychromatic printing with variable sections of yarn in distaffs, thus obtaining a general operating simplification with consequent saving of costs, time and labour. In addition, it carries out a printing system which does not require the employ of the above solution in excess.
- the machine synthetically consists of: a) an injection needle assembly which lays down the colour solutions by penetrating into the distaff inside; b) a squeezing and compressing device which equilizes the distribution of the coloured solutions; c) a colour cooking device consisting of some stocking containers and of as many dosing ones (a little smaller than the previous ones) for distributing the coloured solutions to the injecting needles; d) an autoclave foreseen for the different fixing, washing and print ed distaff extracting operations; e) a robotized and centralized system for automatic distaff charging and discharging.
- Substantially the operation cycle foresees the positioning of the distaffs on housings 49 fitted in a rotating system 26 by means of a robot system 44 with arms, which carries out three different operations at the same time: taking up the distaff to print, in position 43, from the accumulation store 48; drawing of the printed distaff, in position 42, from the rotating system of the printing bench, and the laying down of the distaff separating plate in position 41.
- the robot then carries out other three operations: it lays down the printed distaff on the distaff carrying chariot 46 of autoclave 18; it lays down the distaff to print on the seat fitted on the rotating system now become free after the previous operation; it draws away the plate separating the distaffs from the relevant plate store 45.
- the rotating system foresees four positions: two working ones intercaleted with two other waiting ones.
- the distaff to print, fitted on the rotating system for charging and discharging 28, after the first waiting position 27, is raised by means of a piston 37 as high as the printing bench 24 and it here undergoes an injection action by means of four pneumatic assemblies 36 with needle injectors 35 and subsequently a squeezing and compression action by four pneumatic groups 31 complete with jaws 32.
- the distaff thus printed is laid down on the housing of the underlying rotating system by means of the same piston 37 which previously had taken it.
- the vacuum is obtained, checked by means of the relevant vacuumgauge 1; steam is then introduced directly through the opening of valve 11 into the autoclave until the pressure has been reestablished and as long as wished.
- the operation of the distaff washing starts, the discharge valve 14 is opened, then closed, and the breathing valve 3 opened.
- the required water quantity is introduced through valve 8, checking it by means of level probe 6.
- the bath recirculation pump 23 is started, the water begins to be warmed through the heat exchanger 19, then is cooled and rinsed. After having discharged the machine through valve 14, the operation is started for extracting the most part of the water still remained on the distaffs.
- the coloured solutions to the injecting needles 35 are fed by a colour kitchen consisting of some cylindrical containers 30 far the coloured solution stocking and through the relevant dividing containers 29 foreseen for establishing in advance the exact quantity of solution to inject. This occurs by means of the electronic preselectors, level gauges 40 and sensors 38. As soon as in the dividing containers 29 the wished level has been reached, compressed air is let into them determining a pressure established in advance and checked by means of gauges 39. This allows to transfer the whole quantity of solution selected in advance to the injecting needles 35 and from here on the distaff to print 5.
- the input of the different coloured solutions to the needles 35 can be changed by exchanging, by means of quick connectors, the pipes coming from the colour kitchen and containing coloured substances, so as to obtain a variety of combinations.
- the possibility of establishing in advance the exact quantity of liquid on the distaff enables to avoid an exceeding quantity of solution on the distaffs alltogether and in combination with the compression squeezing and, therefore, to avoid the inconveniencies of the colour percolation.
- Table 4 is the representation of the distaff bearing chariot.
- Table 5 is the representation of the printing device and of the colour kitchen.
- Table 6 is the schematic view of the rotating system 46 with the distaff in ist positioning.
- Table 7 is the representation of the colour kitchen;
- table 8 points out a particular of the colour kitchen concerning the dosing system of the dosing containers;
- table 9 is the representation of the robotized system for the distaff loading and unloading.
