[Industrial applications]

 The present invention relates to a kind of synchronous winding device for a loom, and in particular, has a kind of completely synchronous pulling cloth and winding speed and stable drawing torque, achieves stable drawing cloth and winding operation, The present invention relates to preventing the occurrence of uneven weight per meter and disadvantages of forming a weft due to a pulling torque different from a constant pulling speed.

[0002]

[Prior art]

 The conventional winding device for a loom is as shown in FIG. 1, and includes a bottom seat 81, a pulling motor 821, a winding motor 822, a winding rod 831, a belt 84, a pulling rod 85, and a needle weave rotary disc. 86, needle weave motor 87, and woven cloth 88 are required. The needle-weaving motor 87 drives the needle-weaving rotary disk 86 to rotate the needle-weaving rotary disk 86 to perform a needle-weaving operation. The traction cloth motor 821 drives the traction cloth rod 85 with the belt 84 to rotate the traction cloth motor 821 so that the traction cloth rod 85 performs the drawing cloth operation. Was achieved. However, the conventional winding device for such a loom has the following drawbacks in use. 1. The rotation speeds of the take-up motor 821 and the take-up motor 822 cannot be controlled so as to be completely synchronized, which causes a difference in the rotational speed between the take-up rod 83 and the take-up rod 85. At the same time, it is not possible to match the rotation speed of the needle weave rotary disc 86, and the difference in the two-stage winding speed between the needle weave rotary disc 86 and the draw rod 85, and between the pull cloth rod 85 and the take up rod 83. Therefore, the woven cloth 88 has a problem that the cloth thickness is not uniform (that is, the weight per meter is not uniform), and a defective product is formed. 2. Since the pulling rod 85 is driven by the belt 84 by the pulling motor 821, and the winding rod 83 is directly or indirectly driven by the winding motor 822, adjustment is made so that the difference in rotational speed between the two is completely synchronized. In addition, the pulling rod 85 is affected by the weight of the woven fabric and generates a difference in rotational speed between the take-up rod 83 and the take-up rod 83 to generate a reverse gravity torque. The pulling force of the pulling cloth is formed between the cloth rods 85, and the needle cloth between the pulling rod 85 and the take-up rod 83 is subjected to the uneven pulling force, resulting in the defect that the weft thread is different in density and unevenness. It has become a good product.

[0003]

[Problems to be solved by the device]

 In order to solve the above-mentioned drawbacks of the prior art, the synchronous winding device for a loom of the present invention provides one fixed fixed bevel gear in the bottom seat to engage the take-up bevel gear at the end of the winding shaft. , When the needle-loom turntable drives the side support to rotate around the bottom seat, a relative planetary motion is generated between the take-up shaft and the fixed bevel gear, which allows one appropriate rotation speed for the take-up shaft. The take-up shaft is driven to rotate in synchronization with the rotation speed of the needle weave rotary disc, and the take-up shaft drives one take-up rod through the belt and the inertia wheel to perform a synchronous winding operation. However, due to the difference in the speed of the take-up rod and the needle-loom turntable, the roll between the draw rod and the take-up rod suffers from the drawback of uneven cloth thickness (that is, uneven weight per meter). The main purpose is to completely prevent the above and reduce the occurrence of defective products.

The synchronous winding device of the loom of the present invention further receives the rotation of the pulling rod caused by the planetary operation generated when the side support frame rotates around the bottom seat, and the winding rod pulls the woven fabric. Torque action such as frictional force sometimes occurs, which allows the pulling rod to also maintain a rotational speed that is synchronized with the take-up rod, and in a plurality of pulling rods, the position higher than the other ones. A pulling rod is connected to one end of the pulling rod via a belt, and the end of the pulling rod is connected to a torque motor via a compound bevel gear to provide a stable rotation speed provided by the torque motor. The purpose of the following is to make the pulling rod maintain a stable pulling speed and torque in synchronization with the take-up rod by means of and torque.

 2 and 3 are a front view showing a whole structure of the present invention and a perspective view showing the whole structure. As shown in these figures, the present invention comprises a bottom seat 1, a side support rack 2, a winding mechanism 3, and a pulling cloth mechanism 4. Among them, the bottom 1 of the base 1 is fixed to the ground, the left side thereof is one winding shaft 31 extended from the winding mechanism 3, and the right side is a pulling shaft 41 of the pulling mechanism 4 which is a side bearing on both left and right sides. It is connected to the bottom end of the rack 2, and the top end of the side support rack 2 is fixed to the lower part of the loom 6 of the loom. The needle weave rotary disk 6 is supported by the one main support frame 5, and its power is obtained by the one needle weave motor 61. The winding mechanism 3 has one winding shaft 31, and one lower winding wheel 311 is provided at the left end of the winding shaft 31, and the lower winding wheel 311 is connected to one inertia wheel 32 by one belt 321 and The ring 32 is connected to an upper winding wheel 332 fixed to the left end of the winding rod 33 by a belt 331. The pulling mechanism 4 has a pulling cloth shaft 41, a pulling cloth wheel 411 is provided at the right end of the pulling cloth shaft 41, and an upper pulling cloth fixed to the right end of the pulling cloth rod 42 by a belt 412 hung on the pulling cloth shaft 41. It connects to the ring 421.

FIG. 4 is a cross-sectional view of the bottom seat 1 of the present invention. As shown in the figure, one main shaft 12 is provided at the center of the bottom seat 1, and two main shafts 12 are provided on the upper side and the lower side, respectively. The bearings 122 and 121 are inserted into the uniaxial sleeve 14, and the outer side of the axial sleeve 14 is connected to one composite bevel gear 15 via two ball bearings 131, and the composite bevel gear 15 has upper teeth 152 and A lower tooth 151 is provided, and the upper tooth 152 and a pulling bevel gear fixed to the left end (inner end) of the pulling shaft 41 mesh with each other, and the lower tooth 151 is connected to the torque bevel gear 111 of the one torque motor 11. Be meshed. One fixed bevel gear 124 is fixed to the top end of the main shaft 12, and the fixed bevel gear 124 meshes with the take-up bevel gear 34 fixed to the right end (inner end) of the take-up shaft 31.

The take-up bevel gear 34 at the inner end of the take-up shaft 31 does not operate at the top end of the main shaft 12 when the needle-loom turntable 6 drives the two side supports 2 to rotate around the bottom seat 1. A planetary relative movement is performed with respect to the bevel gear 124, and thereby rotation is generated in the winding shaft 31, and the winding shaft 31 uses the lower winding wheel 311 to interlock the belt 321 to move the belt 331 to the inertia wheel 32. Then, the upper winding wheel 332 is driven. The upper winding wheel 332 rotates the winding rod 33 by interlocking with each other to perform a winding operation. The woven cloth 7 wound up by the winding rod 33 first penetrates between the plurality of upper pulling rods 42, and is located at one end of one which is located at a higher position than the other which is located in the center of the plurality of pulling rods 42. The upper pulling cloth wheel 421 is provided, and the power of the lower pulling cloth wheel 411 provided at the right end (outer end) of the pulling cloth shaft 41 is transmitted to the pulling cloth rod 42 by the one belt 412, and the pulling cloth shaft 41 is the composite bevel gear. The torque bevel gear 111 of the torque motor 11 is connected via 15.

When the needle weave rotary disc 6 interlocks the side support racks 2 and causes the pulling cloth shaft 41 to generate rotational power, the weight of the woven cloth on the winding rod 33 increases as the winding increases. Tension is generated due to gravity falling downward, and the woven fabric 7 between the take-up rod 33 and the pulling rod 42 receives the appropriate pulling force, and the woven fabric 7 on the pulling rod 42 pulls the take-up rod 33. The frictional force at the time of receiving increases the rotational speed of the draw cloth shaft 41 to increase the rotation speed of the draw cloth shaft 41. At this time, the torque motor 11 connected to the draw cloth shaft 41 by the compound bevel gear 15 generates a constant rotation speed with a constant torque. Since it is a motor that operates, when the rotation speed of the draw cloth shaft 41 is increased to the same speed as the needle weaving rotary disk 6, the motor is further synchronously reversely rotated in the opposite direction, so that the winding rod 33 and the winding shaft 31 rotate. Match the speed. If the woven cloth on the take-up rod 33 is relatively light, the frictional pulling force of the cloth that the pulling rod 42 receives is relatively small, so that the rotating speed of the draw rod 42 becomes faster than that of the take-up rod 33. At this time, the torque motor 11 provides one stable rotation speed and torque, and combines the planetary type synchronous dynamic operation operation of the main shaft 12, the take-up shaft 31, and the pulling cloth shaft 41 to achieve stable and stable pulling cloth and winding operation. Achieve the effect of cloth.
