Abstract
The invention discloses a kind of doffing trolleies for being able to achieve precise positioning, including the guide rail being installed on machine, winder trolley is slidably connected on the guide rail, the bottom of the guide rail has been equidistantly positioned several vee-blocks, the winder trolley is equipped with positioning cylinder, the top of the positioning cylinder is connected with the V-arrangement fixture block with vee-block cooperation, be equipped on the winder trolley be able to detect vee-block close to switch.The present invention is once positioned by sensor with the secondary precise positioning for positioning the method combined and realizing doffing trolley of mechanical structure, and repetitive positioning accuracy guarantees within the scope of 0.1mm, substantially increases the accuracy rate and high efficiency of lick-up link.To realize that doffing link unmanned management provides guarantee, it is greatly reduced using number amount, product quality but steadily improves.
Description
Technical field
The present invention relates to technical field of textile machine, are more particularly to a kind of doffing trolley for being able to achieve precise positioning.
Background technique
It, must be by the cylinder yarn that worker expires network from support arm when single ingot issues full cylinder signal in traditional doffing process
It removes, ready bare bobbin is put back into support arm.Also there are some automatic doffing cars at present, doffing trolley is with automatic equipment
Replace artificial doffing, manually put cylinder, workshop unmanned management may be implemented, improves working efficiency.Existing automatic doffing car is logical
It crosses control system control to move in guide rail, after receiving the signal for needing doffing, under doffing moving of car to corresponding spindle
Side, the common doffing trolley of prior art positioning accuracy during traveling is poor, or hand fit is needed to position, some are fixed
Precision good device structure in position is complicated, higher cost.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of doffing trolley for being able to achieve precise positioning, can pass through
Secondary precise positioning is realized in mechanical device cooperation.
To achieve the above object, the present invention provides the following technical scheme that a kind of doffing trolley for being able to achieve precise positioning,
Including the guide rail being installed on machine, doffing trolley is slidably connected on the guide rail, the bottom of the guide rail is equidistantly positioned
There are several vee-blocks, the doffing trolley is equipped with positioning cylinder, and the top of the positioning cylinder is connected with matches with the vee-block
The V-arrangement fixture block of conjunction, be equipped on the doffing trolley be able to detect vee-block close to switch.It is equipped with and leads on doffing trolley
The trolley idler wheels of rail cooperation sliding are respectively arranged with the biography for measuring spindle winding length in equipment above each single ingot subheader
Sensor.Once measuring length reaches full ingot winding length, sensor will issue full ingot signal, and automatic doffing car will pass through height
Precision encoding device realizes position positioning, once positions to realize at this time.
When detecting that the vee-block on guide rail, doffing trolley continue to move close to switch on doffing trolley, opened until close
Pass stops after can't detect vee-block, and the small truck position of doffing is arranged to position origin, i.e. the V-arrangement fixture block of positioning cylinder at this time
Center is directed at the edge of vee-block on guide rail.According to the uncompensation distance set in advance in program, reach doffing moving of car fixed
On the V-arrangement fixture block center alignment guide rail of position cylinder at vee-block position, such as 3(b in Fig. 2) shown at position.In the process, it controls
The stepper motor of doffing moving of car processed is closed, and trolley can be moved left and right easily at this time.Positioning cylinder stretches out, and V-arrangement card blocks fastly
Enter vee-block, such as 3(a in Fig. 2) shown at position, positioning cylinder drives doffing trolley to move left and right realization precise positioning, and it is fixed to repeat
Position accuracy guarantee is within the scope of 0.1mm.The configuration of the present invention is simple, positioning accuracy are good, are able to achieve automatic positioning.
It is fallen in conclusion the present invention is once positioned by sensor with the method realization that the secondary positioning of mechanical structure combines
The precise positioning of cylinder trolley, repetitive positioning accuracy guarantees within the scope of 0.1mm, substantially increases the accuracy rate of lick-up link
With high efficiency.To realize that doffing link unmanned management provides guarantee, it is greatly reduced using number amount, product quality is steady
Step improves.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is partial enlarged view at A in Fig. 1；
Fig. 3 is Fig. 2 right view.
Mark explanation: 1, guide rail；2, vee-block；3, V-arrangement fixture block；4, positioning cylinder；5, close to switch；6, trolley idler wheels.
Specific embodiment
A kind of specific embodiment for the doffing trolley for being able to achieve precise positioning of the present invention is made into one referring to figs. 1 to Fig. 3
The explanation of step.
A kind of doffing trolley being able to achieve precise positioning slides on the guide rail 1 including the guide rail 1 being installed on machine
It is connected with doffing trolley, the bottom of the guide rail 1 has been equidistantly positioned several vee-blocks 2, and the doffing trolley is equipped with positioning gas
Cylinder 4, the top of the positioning cylinder 4 are connected with the V-arrangement fixture block 3 with the vee-block 2 cooperation, are equipped on the doffing trolley
Be able to detect vee-block 2 close to switch 5.Trolley idler wheels 6 with the cooperation sliding of guide rail 1 are installed, in equipment on doffing trolley
On, the sensor for measuring spindle winding length is respectively arranged with above each single ingot subheader.Once measuring length reach full ingot around
Line length, sensor will issue full ingot signal, and automatic doffing car will pass through high-precision encoder and realize position positioning, at this time
To realize primary positioning.
When detecting that the vee-block 2 on guide rail 1, doffing trolley continue to move close to switch 5 on doffing trolley, Zhi Daojie
Nearly switch 5 stops after can't detect vee-block 2, and the small truck position of doffing is arranged to position origin, the i.e. V-arrangement of positioning cylinder 4 at this time
The edge of vee-block 2 on the center alignment guide rail 1 of fixture block 3.According to the uncompensation distance set in advance in program, make doffing trolley
Move on 3 center of the V-arrangement fixture block alignment guide rail 1 of positioning cylinder 4 at 2 position of vee-block, such as 3(b in Fig. 2) shown at position.
In the process, the stepper motor for controlling doffing moving of car is closed, and doffing trolley can be moved left and right easily at this time.Position gas
Cylinder 4 stretches out, and V-arrangement card is caught in vee-block 2 fastly, such as 3(a in Fig. 2) shown at position, positioning cylinder 4 drives doffing trolley to move left and right
Realize that precise positioning, repetitive positioning accuracy guarantee within the scope of 0.1mm.The configuration of the present invention is simple, positioning accuracy are good, are able to achieve certainly
Dynamic positioning.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
