The roller type paper feeding mechanism includes several paper feeding rollers, a paper drawing mechanism comprising one pair of paper drawing rolls and a functional roll in front of the paper drawing rolls. It features that the paper feeding rollers are driven with individual driving units and are controlled with one control system to rotate synchronously and to stop successively from back to front. The present invention without lifting board has high stability, raised production speed and raised product quality.
Description
(1) technical field under
The present invention is a kind of paper feeding mechanical structures in the package packing machine, particularly the structure-improved and the working method thereof of a kind of roller type paper feeding machinery of paper feeding machinery.
(2) background technology
Packed in cases machinery develops into today, and for the subsequent handling of carton production, as cardboard printing, fluting, cross cutting etc., the quality of its product quality depends on the quality of this package packing machine paper advance mechanism performance to a great extent especially.Traditional paper feed mechanism such as chain paper feed mechanism, after play the formula paper feed mechanism, more and more do not satisfy user's requirement at aspects such as paper feeding speed, paper feeding precision, even more serious for crooked, thin cardboard quality problems.
Occurred multiple roller type front edge paper feed mechanism in the case, solved the problems referred to above to a certain extent, the structure and the operation principle of described roller type front edge paper feed mechanism are as follows.
The cardboard casket case that is made of front apron, side shield and backboard above frame, for placing paperboard grade (stock), front apron can make the clearance height of front apron and rack table can pass through for a piece of paper plate just at vertical direction adjustment height.
The paper pushing roller that some configured in parallel are arranged below cardboard casket case, the paper pushing roller of configured in parallel is near front apron, account for greatly cardboard casket case length 1/3rd a little less than, paper pushing roller is made by slightly flexible material, some paper pushing rollers drive rotation synchronously by power set.
Below roller, link to each other and form air intake device with the absorption bellows by airduct by blower fan.
Draw mechanism of paper in the place ahead of cardboard casket case by what motor, gear-driven a pair of draw rollers constituted.
On the table top of the following methods, rack of cardboard casket case, be provided with one move both vertically lift plate, lift plate plate face and offer slotted eye, paper pushing roller exposes from described slotted eye.
When using operation, cardboard that earlier will be to be carried is put into cardboard casket case, opens blower fan, produces negative pressure in the bottom of frame, and cardboard is attracted on the table top and paper pushing roller of below.
Motor movement, the spin friction power of paper pushing roller, the cardboard rolling friction of bottom surface is forwards pushed, cardboard is advanced forward by the slit of cardboard casket case front apron, when cardboard enters two draw rollers in the place ahead, by this draw rollers is seized on both sides by the arms, under both compressing rotations, transport forward, finish the conveying of cardboard.
When cardboard enters in the draw rollers assembly, to be seized on both sides by the arms and pressed when drawing, the paper pushing roller of cardboard casket case below has just stopped rotating operation.
Because each component configuration of machine is fixed, and also fixes from cardboard casket case front apron to the distance between draw rollers.Seize on both sides by the arms when sending into cardboard in draw rollers, the length of different cardboards can produce different results.
When the afterbody of cardboard was positioned at last root paper pushing roller just, paper pushing roller stopped the rotation, and draw rollers can more balancedly be seized on both sides by the arms and be pulled cardboard.
Longer when cardboard, paper pushing roller stops the rotation, and when the cardboard afterbody was positioned at the back of last root paper pushing roller, paper pushing roller stopped the rotation, and draw rollers must just can be seized on both sides by the arms with bigger power and be pulled long cardboard.Easy like this that cardboard is pulled is injured, and two draw rollers are in order to produce bigger friction drag force, and these two draw rollers must be born mutual extruding force, thus, all are a kind of bigger burdens to draw rollers and integral device.
When cardboard shorter, when afterbody is positioned at the front of last root paper pushing roller, paper pushing roller does not stop the rotation as yet, at this moment, time page or leaf cardboard that touches is transported friction in the continuation rotation of paper pushing roller, inferior page or leaf cardboard is stopped improperly that by the place ahead cardboard casket case front apron crack the head end of cardboard can be damaged or press from both sides bad.For this reason, people have increased by a cover with preceding page or leaf and time page separating mechanism that separates, the primary structure of described separating mechanism is one and lifts plate and back and forth lift vertically, fall, lifting plate when the front end of cardboard is seized on both sides by the arms lifts, when paper pushing roller enters the inferior page or leaf of conveying cardboard, lift plate and down fall, the do action that so goes round and begins again is carried, is separated and finish cardboard paper feeding operation.
Though this measure can solve the improper friction of cardboard and carry, can carry cardboard more correctly, accurately, but the separating mechanism of lifting plate is the parts that negative effect is bigger, the highest paper feeding speed can reach per minute more than 200 during the equipment high-speed cruising, lift about 0.3 second vertical tremor of plate once, high-frequency up-down vibration produces the powerful noise and the mechanical shock inertia of huge parts, securing member on parts and the equipment becomes flexible easily, loses, damages, and is an inevitable source of trouble to parts, equipment.And fluctuation of service under the fast state, the paper feeding precision is low.This technology does not change improved effective technology so far having dissolved very grave cost for separating when cardboard contributes.
Chinese patent 200620003004.6 " the front edge paper feed device of corrugated case machine ", do not adopt paper pushing roller and existing separating mechanism technology, the belt group structure that it adopts a kind of periodicity to rise and carry forward, one group of belt promptly is arranged in parallel, lift synchronously again and carry forward, the paper feeding operation is finished in circulation, though this technical scheme has been cancelled the pallet elevator structure, but property synchronizing cycle of belt group ground rises, lateral transfer, the essence of its action does not change, and the defectives such as vibrating noise of rotating generation that rise still exist, and the defective of its essence does not still change.
(3) summary of the invention
Purpose of the present invention is exactly vibration and the noise when reducing machine run, improves the stability of machine high-speed cruising, improves the paper feeding precision, and then improves the quality of products and productivity effect.
Purpose of the present invention is realized by following mechanism.
In the narration to technical solution of the present invention, the direction that cardboard is walked is decided to be the place ahead, otherwise is the rear.
A kind of roller type paper feeding mechanism without lifting board of technical scheme of the present invention, comprise the cardboard casket case that the frame top is made of front apron, side shield and backboard, the paper pushing roller that some configured in parallel are arranged below cardboard casket case, draw mechanism of paper in the place ahead of cardboard casket case by what a pair of draw rollers constituted, in the place ahead of draw rollers one function roller is arranged, it is characterized in that: described each root paper pushing roller is driven by power set difference correspondence separately.
Control the startup of each root paper pushing roller and stop by the roller driving control system.
The working method of a kind of roller type paper feeding mechanism without lifting board of technical scheme of the present invention is characterized in that: described some paper pushing rollers are undertaken by following working method:
When 1. starting, all are rotated synchronously by the paper pushing roller that cardboard covers;
2. in transporting, when cardboard is carried forward, cardboard is in the moment that breaks away from a certain paper pushing roller, and this paper pushing roller stops the rotation immediately;
3. in transporting, cardboard by after break away from paper pushing roller forward in succession, the paper pushing roller that breaks away from cardboard by after stop the rotation successively forward;
4. all stop the rotation until all paper pushing rollers;
5. transport time page or leaf cardboard, repeat 1. extremely 4. process;
6. cardboard has all sent in the cardboard casket case, and all mechanism quits work.
During use, control some paper pushing rollers by the roller driving control system and rotate startup synchronously, can be steady, effectively the cardboard that will be carried on the paper pushing roller is fed forward, when the front end of this cardboard send to that draw rollers constitutes draw in the mechanism of paper time, along with the conveying forward of cardboard, cardboard the covering on some paper pushing rollers also from after expose successively forward, by the control of roller driving control system, the roller that exposes is in succession stopped the rotation.Because the roller that exposes contact with time lower surface of page or leaf, roller moment of exposing stops the rotation, and has also promptly stopped the friction of inferior page or leaf is promoted, and can guarantee that time page or leaf is static not produce moving forward, and the leading section damage that time page or leaf cardboard moves forward and brings can not take place.
And the technical program does not pump lifts plate, does not need the separating action that lifts repeatedly, and equipment can not produce vibration and impact, and has improved the operating mode of equipment, has thoroughly overcome original drawback.
The technical program is in each paper feeding cycle, and the rotation synchronously under the control of roller driving control system of all paper pushing rollers starts, and stops the rotation successively in succession gradually again.Start steadily, stop to reduce gradually the rotation of paper pushing roller, machine sound alleviates, and therefore whole equipment makes a noise very little.
A kind of roller type paper feeding mechanism without lifting board according to the technical program further is that the drive unit of described paper pushing roller is a numerical-control motor.
As numerical-control motor, can select servomotor or stepper motor for use, servo drive system is a kind of with mechanical location or the angle automatic control system as the control object, generally its inside comprises electric current, speed and/or position closed loop.Servo-drive system is a kind of servomechanism, its control is essentially the loop circuit, stepper motor is a principle of utilizing the position decoding device, the revolution of one of motor is divided into 360 deg, the least unit that cooperates Chuan motivation Gou Let to decide the motor transmission again, it is controlled to be out circuit type, and positioning accuracy is slightly poor than servomotor.
A kind of roller type paper feeding mechanism without lifting board according to the technical program, further be, described roller driving control system, as computer, cyclelog etc. according to as described in cardboard casket case front apron to the distance of draw rollers, the rotary speed of paper pushing roller and the length of cardboard, the startup of each paper pushing roller numerical-control motor and the parameter that stops to be set, i.e. paper pushing roller startup and the opportunity that stops.
A kind of roller type paper feeding mechanism without lifting board according to the technical program further is that the message input device of described roller driving control system comprises the rotary encoder that is arranged in the draw rollers (3).
A kind of roller type paper feeding mechanism without lifting board according to the technical program further is that the message input device of described roller driving control system comprises being arranged on cardboard casket case front apron between the function roller, detects the sensor of cardboard in-position.
Described draw rollers and function roller (as forme roller, fluting rotor, template roller etc.) have fixing rotating ratio.But servomechanism is by the rotary encoder in the draw rollers just linear resonance surface velocity and the service cycle of following function roller, and then the linear resonance surface velocity of definite feeding-in roll and paper feeding time; According to the signal that the sensor of cardboard in-position sends, accurately the pair roller driving control system is controlled, and makes whole paper feeding action go round and begin again operation regularly when page or leaf and time page or leaf cardboard operation, finishes intermittently paper feeding function, until all having sent.
What the technical program adopted is that some paper pushing roller single serves drive, and has cancelled paper feeding and has lifted plate, and intermittently the realization of paper feeding action is to lean on the priority of each feed roller to realize actuation time.All feed rollers remain static before the beginning paper feeding, have so just guaranteed fully contacting of cardboard and feed roller, and cardboard adhesive force is big.Eliminate the vibrations and the noise of machine, improved the stability of machine, improved the paper feeding precision.
A kind of roller type paper feeding mechanism without lifting board according to the technical program can be that the quantity of paper pushing roller is greater than four.
It is to send omnidistance 2/3rds distance approximately forward at cardboard that plate is lifted in the separation of prior art, after entering between draw rollers, cardboard just begins to lift, both made this moment cardboard under the power that follow-up draw rollers is seized on both sides by the arms, continue to carry, liftable again before the page or leaf cardboard continue to be drawn the paper pushing roller that exposes after sending can not touch time page or leaf cardboard again and produce unwanted mistake conveying.Therefore, the quantity of the paper pushing roller of prior art is generally three, mostly is four most, all concentrates to be arranged in parallel within the cardboard casket case near the front apron section.
The separation principle of the technical program is thoroughly changed, and therefore, the quantity of paper pushing roller is not limited to four, can lay the paper pushing roller of requirement below cardboard casket case according to the payload of transporting cardboard, even be paved with.Thus and thus, not entering seizing on both sides by the arms of draw rollers as yet at cardboard presses when drawing, long cardboard is under more paper pushing roller promotes, transport reposefully more effectively,, whenever send the distance of a paper pushing roller, after promptly whenever exposing a paper pushing roller, stop the rotation, can not produce the mistake friction and carrying time phenomenon of page or leaf cardboard in control following moment of roller driving control system.
To be each root paper pushing roller at cardboard broken away from the separate mode of the technical program stops the rotation immediately after friction is transported, make the transporting power of each root paper pushing roller be utilized to the fullest, the carrying capacity of whole paper pushing roller is enhanced, unlike prior art, for fear of paper pushing roller the mistake of inferior page or leaf is carried, when forward paper pushing roller as yet not paper feeding finish just to allow and lift plate and lift its disengagement, can not give full play to the paper feeding power of all paper pushing rollers.Therefore, the technical program requires to have reduced to the drag force of draw rollers, also makes draw rollers to compress cardboard distortion has reduced to cal(l)iper.
During startup, all are rotated synchronously by the paper pushing roller that cardboard covers, like this, when cardboard is shorter in length than the length of many paper pushing rollers layings, the paper pushing roller that is covered by cardboard does not rotate, make a nothing lift the cardboard input that plate roller type paper feeder can be suitable for multiple different length, and can not produce such as phenomenons such as part paper pushing roller idle running.
This measure has shown that the technical program is than the another outstanding advantage of prior art.
Generally speaking, the technical program provides a kind of roller type paper feeding mechanism without lifting board, changed to essence in the existing paper feeding machinery by lifting plate and lifted up and down and fall the principle and the structure of separating, eliminated the noise that vibration and vibration bring, to rocking of equipment, to the absent-mindedness of parts, to the skew of precision, to the influence of mechanical life.And increased the paper feeding ability and the efficient of paper pushing roller, and alleviated the pulling load of draw rollers, reduced deformation effect to cal(l)iper.Improve the kinetic stability of machine under fast state, improved the paper feeding precision, improved speed of production and product quality.Be mechanically revolutionary change and progress of paper feeding.
