According to actual braided fabric requirement, sometimes to weave simultaneously with two yarn mouths, generally need not adjacent two yarn mouths, the angle between such two yarn mouths is large, and exchange is convenient, placed in the middle easily before and after the yarn mouth.Consider above-mentioned factor, the state of the first cam 61, the second cam 62, the 3rd cam 63, four-cam 64, the 5th cam 65, the 6th cam 66, the 7th cam 67 and the 8th cam 68 is optimized as shown in Figure 3, and wherein the cam bit state of the first cam, the second cam, the 3rd cam and four-cam is as follows:
The first cam bit of the first cam 61, the second cam 62, the 3rd cam 63 and four-cam 64 is outstanding;
The second cam bit of the first cam 61, the second cam 62 and four-cam 64 is outstanding, the second cam bit depression of the 3rd cam 63;
The 3rd cam bit of the first cam 61, the second cam 62 and the 3rd cam 63 is outstanding, the 3rd cam bit depression of four-cam 64;
The four-cam piece of the first cam 61, the 3rd cam 63 and four-cam 64 is outstanding, the four-cam piece depression of the second cam 62;
The 5th cam bit depression of the first cam 61, the 5th cam bit of the second cam 62, the 3rd cam 63 and four-cam 64 is outstanding;
The 6th cam bit depression of the first cam 61, the 3rd cam 63, the 6th cam bit of the second cam 62, four-cam 64 is outstanding;
The 7th cam bit depression of the first cam 61, four-cam 64, the 7th cam bit of the second cam 62, the 3rd cam 63 is outstanding;
The 8th cam bit of the first cam 61, the 3rd cam 63 is outstanding, the 8th cam bit depression of the second cam 62, four-cam 64;
The cam bit state of the cam bit state of the 5th cam 65, the 6th cam 66, the 7th cam 67 and the 8th cam 68 and the first cam 61, the second cam 62, the 3rd cam 63 and four-cam 64 is symmetrical.
Described symmetry refers to that the first cam 61 is identical with the 8th cam 68, and the second cam 62 is identical with the 7th cam 67, and the 3rd cam 63 is identical with the 6th cam 66, and four-cam 64 is identical with the 5th cam 65.
Take the first cam 61, the second cam 62, the 3rd cam 63 and four-cam 64 as example, the first cam bit that original state is given tacit consent to all cams 6 is positioned at ejector pin 8 tops (namely the first cam bit contacts with ejector pin 8, or contacts with ejector pin 8 by bearing 7).
Above-mentioned eight color replacing mechanisms course of work under motor 13 drives is as follows:
After the driven by motor cam set rotated counterclockwise 45 °, the switching slide block 2 of the 3rd cam 63 correspondences falls selected the thread-carrier balladeur train, and the first cam 61, the second cam 62 and four-cam 64 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of four-cam 64 correspondences falls selects the thread-carrier balladeur train, and the first cam 61, the second cam 62 and the 3rd cam 63 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of the second cam 62 correspondences falls selects the thread-carrier balladeur train, and the first cam 61, the 3rd cam 63 and four-cam 64 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of the first cam 61 correspondences falls selects the thread-carrier balladeur train, and the second cam 62, the 3rd cam 63 and four-cam 64 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of the first cam 61, the 3rd cam 63 correspondences falls selects the thread-carrier balladeur train, and the second cam 62, four-cam 64 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of the first cam 61, four-cam 64 correspondences falls selects the thread-carrier balladeur train, and the second cam 62, the 3rd cam 63 are packed up and do not selected the thread-carrier balladeur train; After continuing to rotate counterclockwise 45 °, the switching slide block 2 of the second cam 62, four-cam 64 correspondences falls selects the thread-carrier balladeur train, and the first cam 61, the 3rd cam 63 are packed up and do not selected the thread-carrier balladeur train.
Even if corresponding unselected switching slide block 2 falls and selects the thread-carrier balladeur train in the above-mentioned of short duration time, can not drive the guide balladeur train that need not to select yet.This kind situation is the result that a plurality of color replacing mechanisms of a motor 13 drivings produce, if adopt two cams of a driven by motor, then as long as alternately have a rest with unified up and down; The of short duration process of packing up afterwards that falls first that the irrelevant switching slide block that occurs when switching can not occur respectively switching between the slide block.
The initial position of the first cam bit of all cams 6 of above-mentioned acquiescence is positioned at ejector pin 8 tops (being original state), but be that what cam bit is positioned at ejector pin 8 tops when not limiting original state, the original state of described cam can be that the first cam bit is positioned at ejector pin 8 tops, also can be that arbitrary cam bit is positioned at ejector pin 8 tops in the second cam bit, the 3rd cam bit, four-cam piece, the 5th cam bit, the 6th cam bit, the 7th cam bit or the 8th cam bit.
For example, when the 3rd cam bit of all cams 6 is positioned at ejector pin 8 top (original state), the switching slide block 2 of the second cam 62 correspondences falls selects the thread-carrier balladeur train, and the first cam 61, the 3rd cam 63 and four-cam 64 are packed up and do not selected the thread-carrier balladeur train; Select the thread-carrier balladeur train if want this moment the switching slide block 2 of the 3rd cam 63 correspondences to fall, then clockwise rotate 90 ° as long as motor 13 drives all cams 6.
In like manner, the course of work of the 5th cam 65, the 6th cam 66, the 7th cam 67 and the 8th cam 68 and selection principle are all identical.
The concrete outcome that each cam 6 rotates as shown in Figure 4, and is corresponding among Fig. 4 cam 6 schematic diagrames and Fig. 3.
Because one group of cam that the first cam 61, the second cam 62, the 3rd cam 63, four-cam 64 forms adopts respectively two independently motor-driven with another group cam that the 5th cam 65, the 6th cam 66, the 7th cam 67, the 8th cam 68 form, so eight kinds of states of one group of cam can be organized with another eight kinds of state any combination of cam.
" " represents cam 6 surfaces (being curved surface) depression this moment among Fig. 4, and corresponding switching slide block 2 falls chooses the thread-carrier balladeur train; It is outstanding this moment that " zero " represents cam 6 surfaces, and corresponding switching slide block 2 does not fall, thereby can not choose the thread-carrier balladeur train.The angle that the angle representative clockwise rotates.And cam 6 rotates the different conditions of different angles acquisition shown in following table 1,2 under driven by motor:
Table 1 cam calibration rotary state table
Table 2 cam calibration rotary state table
Represent cam 6 surface depressions this moment in the table 1,2, corresponding switching slide block 2 falls chooses the thread-carrier balladeur train; Zero represents cam 6 surfaces gives prominence to this moment, and corresponding switching slide block 2 does not fall, thereby can not choose the thread-carrier balladeur train.The angle that number of degrees representative in the table 1 rotates counterclockwise.
The above-mentioned situation of only introducing four cams 6 of motor 13 drivings is when 13 in a motor drives a cam 6, as long as the curved surface of the simplest cam 6 possesses a ledge and a sunk part.When a motor 13 is selected to drive a plurality of cam 6, will consider that then the selection of one or more thread-carrier balladeur trains do not interfere other not have selected thread-carrier balladeur train, this just need to be in optimized selection the virtual condition (being that cam 6 surface curve are outstanding or depression) of each cam bit of cam 6.
Another embodiment of the utility model as shown in Figure 5, described switching slide block 2 can be arranged on the pedestal 12 up or down, the cam 6 of motor-driven (being not limited to motor-driven) is installed in the top of switching slide block 2, the top of switching slide block 2 contacts with the curved surface of cam 6, also be provided with resetting means on the described switching slide block 2, turn to when contacting between the sunk part curved surface with cam 6 switching contacting between the ledge curved surface of slide block 2 tops and cam 6, described resetting means upwards resets switching slide block 2.
Equally, for the curved surface that reduces cam and the frictional force between the ejector pin, cam 6 and switch between the top of slide block 2 and be provided with bearing 7.
Described resetting means is to be set in the spring 9 that switches on the slide block, and the upper end of described spring 9 is fixed on the upper end of switching slide block 2, on its lower end is fixed on the pedestal 12.
During work, present embodiment is identical with above-described embodiment mechanism, and the process that difference is to select to switch slide block 2 is opposite, because this embodiment switches on the slide block 2 but act directly on by lever 3.When the ledge curved surface of cam 6 contacts with switching slide block 2, select the thread-carrier balladeur train, and when the sunk part curved surface of cam 6 contacts with switching slide block 2, then do not select the thread-carrier balladeur train.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
