Description
Technical Field
The invention relates to the technical field of weaving equipment, in particular to a vertically-driven shedding mechanism.
Background
An shedding mechanism is required during the weaving process. The current common shedding mechanism is usually provided with a group of output rods rotating around a shaft, each output rod is connected to a palm frame of the loom through a corresponding connecting rod structure, the output rods are enabled to swing alternately by a cam or other eccentric linear driving mechanisms, the corresponding palm frame is driven to vertically move up and down through the connecting rod structure, and the palm frame drives warp yarns to move up and down to realize various shedding actions. An easy-to-implement driving mode is that the output rod reciprocates between two positions, so that the palm frame is driven to reciprocate at the upper position and the lower position through the connecting rod structure.
The cam mechanism can be driven by a driving main shaft, but the opening scheme is basically determined by the shape of the cam, and the time for replacing the cam mechanism each time is more than 2 hours, so that the cam mechanism cannot meet the requirement of small-batch production with multiple flowers.
The motor is used for driving the opening mechanism, so that the movement of each output rod can be independently controlled, and the electronic control is easy to realize. For example, chinese patent application CN109881326a discloses an electronic shedding device for a loom, in which a driving mechanism is provided with a plurality of servo motors and speed reducers, a linear driving mechanism includes an eccentric shaft assembly and an inclined connecting rod, a four-bar mechanism is formed by an adjusting blade, the inclined connecting rod and the eccentric shaft assembly, the rotation of the eccentric shaft is converted into the swing of the adjusting blade, and finally, the two vertical connecting rods drive the palm frame to move up and down.
Such an opening mechanism using a servo motor is easy to realize automatic control, but requires lubrication by engine oil due to the existence of an eccentric linear driving mechanism for converting circular motion into reciprocating motion. As machine operating speeds continue to increase, the likelihood of oil leakage increases and the design of effective seals becomes more complex. Meanwhile, in order to facilitate maintenance, a driving motor of the shedding mechanism is usually arranged at one side of the loom, and in consideration of interference, certain space is required for motor distribution (for example, for a structure of 16 palm frames, 8 motors are usually adopted to be respectively and oppositely arranged), so that on one hand, the occupied area is increased, and on the other hand, the using amount of various metal workpieces is large, and the cost is increased.
If the palm frame can be driven by a linear motor, the motor system can be moved above the loom without occupying floor space. However, in order to obtain a sufficient driving force, the linear motor occupies a thickness space of at least 3.5 cm, whereas for a 16-sheet palm frame loom, the installation space in the thickness direction of each sheet palm frame is only about 1.33 cm, which is obviously problematic.
Chinese patent No. CN114427138A discloses an opening mechanism, which comprises a palm frame and a linear driving mechanism, and is characterized in that: the linear driving mechanism is arranged above the palm frame and provided with a first rotating shaft and a multi-arm transmission part rotating around the first rotating shaft, the multi-arm transmission part is provided with a palm lifting arm and two output arms, and the upper end of the palm lifting arm forms an input end and drives the palm frame to move up and down; a linear motor is arranged corresponding to each palm frame, and a rotor of the linear motor is pivoted with the input end of the palm lifting arm through a connecting sheet; every 2 linear motors that correspond to the palm frame form a set, two linear motor movers in the same set are oppositely arranged, count along the first rotation axis direction, the linear motors of odd-numbered groups are located one side of the palm lifting arm, the linear motors of even-numbered groups are located the other side of the palm lifting arm, one set adopts a short connecting sheet, and the other set adopts a long connecting sheet in two adjacent sets on the same side.
The application of the linear motor in the shedding mechanism is realized, so that the problem of pollution caused by engine oil leakage in the prior art is solved, and the following problems still exist: 1. the linear motors are arranged on two sides above the machine body, and possibly exceed the width of the machine body during installation, so that the positions of the channels between the devices are occupied, and the use is affected; 2. the linkage mechanism is complex, the types of parts are many, and the cost is increased, so the problems need to be overcome.
