Description

Ribbon Needle Room {Ribbon needleloom}

The present invention relates to a ribbon needle room with a shed-forming heddle device according to claim 1.

The ribbon needle-room type that initially presented the sed-forming infant was known in many cases. Infants have carts. The latter has the problems of instability in the case of larger volumes and / or higher rotational speeds of the ribbon needle room. Carr rails are easy to bend, and there is not enough power between carr rails. These problems lead to the destruction of the ingots.

It is an object of the present invention to improve the ribbon needle room type presented earlier.

The present invention consists of the features of claim 1. Since the ingot has at least one carp support with a hollow rod together with the upper water supply pipe of the upper carousel and the lower water supply pipe of the lower carousel, the carp support can be reinforced at any point on the cartle, Can be attached continuously. The inwing rails at the edges are connected via pressure rods arranged in hollow rods, and in the pressure rods on the ends of the hollow rods, the inwing rails are held by the tension screws arranged in concentric axes. This approach is provided with a substantial stiff member in the intle, allowing the latter to fit larger volumes, and / or vice versa, for higher rotational speeds. However, such carp supports may be used as the basic configuration of the cartle, that is, the carp supports may be used as a means of connecting the upper and lower carousel.

The ribbon needle room in claims 2 to 3 will be described in detail.

According to claim 2, the at least one feed pipe has a side support flange in the direction of the hollow rod when the brace of the inwing rails is improved.

The hollow rod is made of hard material. There is a detailed description according to claim 3; However, with the hollow rods, the hollow rods face each other on both sides, the gaps are evenly spread over the length of the hole scale and laid side by side, so that the moved mass is significantly reduced. In the description of claim 4, as the hollow rod consists of a slidable plastic reinforced with fibers, this also saves volume.

Due to the carp feeder 20, the weft yarn 24 is supplied from the yarn spinning wheel 22 to the weft needle 6, which is supplied from the weft loop to the sed 18. Although not shown in detail, in order to bind and secure the inserted weft loops, successive weft loops may be bundled by themselves and into a single thread 26 which is fed to the knitting needle through a thread feeder 28 thereon. May be tied up.

2 to 4, a first carb, which is firmly connected to the cam drive 34 on the one hand and to the pneumatic feedback machine 36 on the opposite side, respectively, due to the link 32; 10 is shown. The cam drive 34 has swing levers 38, 38a, 38b, 38c, 38d connected to the drive point 46 with the cams 42 of the camshaft 44. At the drive point 46, the pivot levers 38, 38a, 38b, 38c, 38d connect to the links 32 via the joint 48. The pivot axes are defined by a joint 48 which moves at right angles to the surfaces spanned by the ingots 30, 30a. The distance A of the turning levers 38, 38a, 38b, 38c, 38d from the respective turning axes 50, 50a, 50b, 50c, 50d to the driving portions 40, 40a, 40b, 40c, 40d. ) Is different between adjacent turning levers, so that the distance B from the turning axes 50, 50a, 50b, 50c, 50d to the driving point 46, 46a, 46b, 46c, 46d is also different, As shown in FIG. 1, the ingots are continuously changed to different sizes to make the sheds wider and narrower. In order to reliably compress the piston at the operation frequency of the cam drive 34, the pneumatic feedback device 36 connected to the link 32 is formed in the gas chamber 52 in the reciprocation of the piston 54. The pressure relief valve 56 connected to the gas chamber 52 limits the maximum pressure in the gas chamber. The compressed gas source 60 is connected through a non-return valve 58 to regulate the gas pressure in the gas chamber 52. Although not shown in detail, the compressed gas source 60 is connected to a controller such that the gas pressure in the gas chamber can be set to an operational state function of the ribbon needle room.

FIG. 5 shows the infant 10a returned by the feedback spring 61 in which the pneumatic feedback machine 36 acts on the ingots 30 and 30a.

The ingots 30 and 30a are formed by upper and lower carr rails 62 and lower carr rails 64 interconnected by the carr support 66. The carp support 66 shown in more detail in FIG. 3 has a hollow rod 68 formed of metal or a preferred fiber-reinforced plastic. Opposite hollow rods 68 include gaps 70, which extend along the length of the hollow rods, and are arranged next to each other. The upper inlet rail 62 is inserted into the upper side water supply pipe 72 and the lower inlet rail 64 is inserted into the lower side water supply pipe 74. At least one of the supply pipes 72, 74 has a support flange 75 in the vertical side direction. Inwing rails 62 and 64 at the edge are interconnected by pressure rods 76. At the upper end of the hollow rod 68, the tension screw 78 is screwed to the hollow rod 68 and presses the upper inlet rail 62, eventually leading to the upper inlet rail 62 through the carp support 66. In order to strengthen the connection between the lower inlet rail 64, the inlet rails 62 and 64 are tensioned by mutual compression stress. As shown in FIG. 2, the plurality of carp supports 66 are arranged to spread evenly along the length of the ingot. Between the upper inlet rail 62 and the lower inlet rail 64, the rope chamber 16 is arranged with the ingots 80 with the eyelets 82 through the movement in each case.

6 and 7 show that the infant baby 80 is aligned with the upper carousel 62 and the lower carousel 64 due to the upper eye 84 and the lower eye 86. The preferred design is shown. In this example, the driving rail 62 is a thin leg 88 which projects horizontally with respect to the surface of the inrail rail 62 and engages with the micro-gap of the clasp element 90 of the associated eye 84 of the carp 80. There is). The end eye 84 assigned to the driving eye rail 62 completely surrounds the in eye rail 62, and is formed between the leg 88 of the driving eye rail 62 and the latch element 90 of the end eye 84. This gap ranges from 0.01 mm to 0.3 mm. This is because the thickness of the leg 88 and the width of the clasp element 90 are mutually adjusted so that the clearance between the leg 88 and the clasp element 90 may be 0.01 mm to 0.3 mm. As shown in FIG. 7, in spite of this microgap, it is possible to have the preferred lamellar cell system at an angle α, which is 15 ^o with respect to the vertical. The lower inlet rail 64 may be configured similarly to the upper inlet rail 62, and possible vertical gaps may be 0.5 mm to 10 mm. For example, the lower carousel 64 does not drive the car 80, but rather absorbs the lateral forces caused by the guide of the carttle and the moved rope chambers 16. By virtue of this configuration of the infant, the infant has only very little noise, and in the case of the maximum circulation rate, the abrasion is minimal even at 4000 to 6000 revolutions per minute, for example.

8 and 9 show a lead device 92, a weft needle 94, a knitting needle 96, and a child 10 connected to the main drive shaft 4, via a single-stage gearwheel mechanism or worm gear.

Since the shared disk 102 with the weft needle 94, knitting needle 96, and the crank 104 is arranged on the main drive shaft 4, the upper crank of the crank pins 106, 108 In order for the eccentricity to be set, there are radially opposite crank pins 106, 108 guided radially, in the grooves 110 of the disc 102 or the crank 104. The crankpin 106 assigned to the weft needle 94 has a coupling rod 112 with a rocker lever 114 articulatedly connected to an upper rocker lever 118 via a coupling rod 116. ). The latter is fixed to the shaft 120 which drives and carries the weft needle 6. The lid device 92 is connected to a rocker lever 124 carrying the lid 7 by a crank pin 108 connected via a coupling rod 122. Knitting needle 96 is arranged to engage the dock 128 of the main drive shaft 4 and the two rocker lever 130. The knitting needle 132 is fixed to the rear end of the rocker lever 124 toward the surface away from the dock 128 because the knitting needle is the knitting needle which acts on one side of the ribbon provided and binds to the inserted weft loop. .

Figures 10 and 11 show the area weaving the ribbon needle room. The guide plate 134 having the guide track 136 arranged on the side of the knitting needle 132 toward the surface away from the sed 18 is a method of hooking the knitting needle 132, the weft of the weft loop 140. The leg 138 is at or below a position similar to the knitting needle head 142 of the knitting needle 132 while being supplied to the sed 18. As a result, when the weft needle 6 is out of the knitting needle head 142, the weft leg 138 may be supplied toward the loop of the knitting needle. This design can, in particular, be suitably meshed with knitting needles 132 for the special handling of the weft legs 138, which is within a very small and effective range. This ensures that the stroke of the knitting needles is kept very low, even though proper tucking of the weft legs by the arms of the knitting needles is ensured. This design also makes it possible to have short knitting needles that are not susceptible to bending, vibration and wear. This also makes the ribbon needle room high performance.

12 and 13 illustrate a yarn feeder 20 suitable for the weft 24. The weft 24, which is occupied by the wheel 22 due to the seal carrier 144, traverses through the duct 148 occurring in the writer 150 to reach the pneumatic compensator 146. The weft 24 fed at a constant speed by the yarn carrier 144 immediately goes to the weft needle 6, and as a result, between the two weft inserts supplied by the writer 150 to the virtue 148. Wefts are not needed and occur on the carrier 152. Guide eye 154 to weft 24 is between compensator 146 and weft needle 6. Instead of the writer 150, it may be replaced by an inhaler or additionally connected to the duck 148.

FIG. 13 is a section XIII-XIII section of FIG. 12 showing a seal carrier 144 for enabling the setting of the conveying speed of the weft yarn. The seal carrier 144 includes a conveying roller 158 arranged on the shaft 156 and is provided with a friction surface 160. The friction surface 160 expands radially due to the movable device 162, so that the circumferential speed of the transport roller 158 can be set. The movable device 162 includes a movable block 164 configured to be incompressible other than an elastic material. The movable block 164 is arranged between the shaft 156 and the stop disk 166 and the movable disk 168, and may be compressed due to the movable nut 170 entering the shaft 156. As compression increases, the casing 172 of the transport roller 158 expands, resulting in a change in the diameter D of the casing and consequently the circumferential speed of the casing. The weft 24 to be conveyed is conveyed while being pressed toward the conveying roller 158 by the pressure roll 174.

14-19 show a yarn carrier 175 in which a rotating conveyor belt 176 that carries the weft 24 is guided between two conical regulating disks 180, 182 arranged on a drive shaft 178. It is shown in detail. The axial distance between the adjusting discs can be set. The reason is that the adjusting disks are compressively stressed with each other due to the spring 184. The conveyor belt 176 is guided through the deflection roll 186 thereon, the distance of the adjustment disks in the deflection roll can be set by the regulator 188. The conveyor belt shown in FIGS. 16 and 17 has a joint 190 of thickness d. On the lower end side of the joint portion, the horizontal rib 192 is formed completely at a height h longer than the thickness d of the joint portion 190. The joint 190 is provided with a reinforcement insert 194. 18 and 19 show the detailed design of the conveyor belt 176a additionally provided on the transverse transverse ribs 196 on the upper side.

As shown in Figs. 14 and 15, the thread carrier is further provided with a pressure roll 198 between the adjusting disks 180, 182 and the deflection roll 186, in order to guide the conveyor belt in a serpentine shape. It is. In the serpentine shape guidance area, the weft 24 to be transported is received and laid down.

Thread carriers are particularly suitable for wefts. In the case of double ribbon needle rooms which produce a plurality of ribbons simultaneously and in parallel with each other, such a plurality of carriers are arranged side by side in the shared drive shaft 178 and the shared pivot shaft and due to the share regulator 188. It may be preferably set.
