Description
Technical field
The present invention relates to a kind of printer, in particular to a kind of suspended type printer suitable for perpendicular.
Background technique
In traditional printing device, printing type mainly uses horizontal plane to print, and print object is also mainly paper.Such as
Usually office ink-jet printer used is moved left and right on cross slide way by drive print head, then cooperates paper in front and back
The feeding in direction is completed to print in a manner of scanning.Also have and keep paper motionless, beaten by the control of orthogonal two guide rails
The X of print head in the same plane completes to print to the movement with Y-direction, and this printing type can be applied to beating for vertical plane
Print.Due to being limited by rail length, in vertical plane, limited extent is printed, if printing plane is too high, the installation of guide rail is difficult
It spends also big.
Summary of the invention
To solve the deficiencies in the prior art, suspended type perpendicular printer is provided, this printer arrangement is reasonable, installation
It is convenient.
To achieve the above object, the invention adopts the following technical scheme:
Suspended type perpendicular printer, including print head are equipped with stepper motor, two synchronous belts in the two sides of print head
One end is fixedly connected with the two sides of print head respectively, and two synchronous belts are fixed after bypassing the output shaft of stepper motor respectively with weight
Connection.
Above-mentioned suspended type perpendicular printer, is equipped with rotary angular encoder on the output shaft of motor.
Above-mentioned suspended type perpendicular printer, side-lower is equipped with universal wheel in print head.
The fixing end of above-mentioned suspended type perpendicular printer, synchronous belt and print head is set to interior above print head
Side.
The motor for printing both sides of head is fixed on the upper end of perpendicular by the present invention, by control two sides motor steering with
Revolving speed reaches the length variation of control synchronous belt, is printed so as to mobile print head in vertical plane.
Universal wheel can not only reduce print head and print the friction between plane, and be suitable for print head along unconfined
It is moved print head track.The medial surface of print head refers to print head close to the one of vertical metope to be printed in the present invention
Side.The present invention is suitable for generally vertical plane, and perpendicular to be printed is possible to locally can have certain inclination, together
Step band is fixed on the medial surface above print head, by the adjusting of synchronous belt this fixed point and print head self gravity, keeps
Print head is bonded with perpendicular, remains unchanged print head at a distance from perpendicular, reduces printing error.
Present invention installation is rapid and simple, maximum magnitude, the peace vertical plane in related with the length of synchronous belt of printing
Dress is not limited by height off the ground, is very suitable to the live air brushing of metope.
It is weight at G1, G2, structure is using two weights, the gravity of print head itself as shown, being motor at A, O
Synchronous belt is tensed, by A, the motor driven at O changes synchronous belt OP, the length of AP, thus mobile print head.
To guarantee that printing precision needs to guarantee that print head in the real-time location information of vertical plane, is established by origin of motor O
Polar coordinate system can calculate polar coordinates of the print head with respect to O point according to trigonometric function.
Enable l0=OA, l1=OP1,l'1=AP1,l2=OP2,l'2=AP2
If motor speed is respectively n at A, O1,n2, time t can then calculate synchronous belt OP, and AP is in moving process, point
P1, P2Locate belt length variation.
l2=l1+n1×t
l'2=l'1+n2×t
By calculating the length of two synchronous belt belt lengths in real time, print head location point under polar coordinates can be calculated:
xn=ln
Control for motor, if print head uses scan-type working method, print head is mainly both horizontally and vertically
Upper movement.If print head level is moved to the left, motor O reversion, motor A reversion；Print head moves right, and motor O is rotated forward, motor
A is rotated forward.
When horizontal movement, print head and OX remain horizontal, i.e. movement intermediate cam shape △ OPA area is constant always, by
This can determine the constraint relationship of revolving speed between two motors.It is in office to mean position PnPlace, triangle area calculation formula are as follows:
In horizontal movement, triangle triangle area is calculated in real time, according to area invariance principle, motion conditions is carried out real
When feedback control.
When vertical up-or-down movement, one, motor rotates forward a reversion, and the displacement component of band in the horizontal direction is constant, to electricity
The constraint of machine revolving speed are as follows:
l1×cosθ1=l2×cosθ2
l'1×cosθ'1=l'2×cosθ'2
If print head uses the working method of intended trajectory printing, coordinate bit of the track in the case where setting polar coordinate system is calculated
Set, calculate the length of two belt lengths under each location point, by driving motor change two tractions without the mobile printing of length
Print head reaches specified tracing point, is printed.
The stabilization carved and keep the tensioning of synchronous belt to keep print head is taken in print head moving process.Of synchronous belt
The gravity of frictional force, weight that clamp force is mainly formed by the driving force of motor and the weight component in mobile cabin itself provide, when
Print head is in moving process, and no matter motor rotates forward, reversion is synchronized due to the effect of weight pulling force and print head self gravity
Band is in a tensioning state always, it is ensured that does not slide.

Specific embodiment
Referring to attached drawing, suspended type perpendicular printer, including print head 1 are equipped with stepper motor in the two sides of print head
4, two 3 one end of synchronous belt respectively be fixedly connected at left and right sides of print head, two synchronous belts bypass respectively the left and right sides step
It is fixedly connected after into the output shaft of motor with weight 2, the fixing end of synchronous belt and print head is set to the inside above print head；?
Rotary angular encoder is installed on the output shaft of motor；Side-lower is equipped with universal wheel 5 in print head.
When in use, it for example applies in higher metope air brushing, the motor of the two sides of print head is fixed by triangle
Frame 6 is mounted on the wall the two sides at end, according to the size of printing surface, installs the synchronous belt of suitable length, passes through rotary angle
The rotational angle that encoder obtains motor output is spent, is printed to control movement of the print head on perpendicular.Work as wall
Face passes through the synchronous belt fixed point and print head itself being fixed on the inside of print head there are when outer oblique and interior local out-of-flatness tiltedly
Gravity, make print head fitting with metope on, keep print head it is constant at a distance from metope, reduce printing error.
When metope is shorter, A-frame can be placed on the ground of metope two sides, motor is fixed on triangle branch
Frame upper end and the two sides for being pressed on metope upper end.This fixed form is also that can satisfy the mobile requirement of printer.Motor
Fixed form is routine techniques, is repeated no more.
Electronic control is routine techniques between printing head and synchronous belt, is not repeated in the present case.
