Said further draw frame machine comprises some ventilation external members that are positioned at conplane suction nozzle and are tightly connected with said suction nozzle.
Said further motion assembly comprises horicontal motion mechanism, be located on the said horicontal motion mechanism with lifting mechanism that moves up and down and the induction control unit that is used to control said horicontal motion mechanism and lifting mechanism motion, and said draw frame machine is arranged on the said lifting mechanism.
Said further horicontal motion mechanism comprises the horizontal guide rail that is arranged on said paper platform and paper receiving device top, and is slidingly installed in the horizontal slip mechanism on the said horizontal guide rail.
Said further lifting mechanism comprises the riser guide that is installed in the said horizontal slip mechanism, and is slidingly installed in the up-down slide mechanism on the said riser guide.
Said further induction control unit comprises that being arranged on said horicontal motion mechanism next door is used to control the optical pickocff of said horicontal motion mechanism motion and is arranged on the pressure sensor that is used to control said lifting mechanism motion on the said draw frame machine.
Said further paper receiving device is conveyer mechanism or manipulator.
Technique scheme has following beneficial effect at least: the utility model embodiment replaces manual work to fail paper work through the automation of adopting machine; Guarantee the stationarity of conveyance of sheets; Eliminate the defect ware that the fatigue that produces owing to manual operation produces, reduced quality risk; And this mechanism can regulate the speed of action, is guaranteeing can to adapt to higher production under the product quality premise; Adopt this mechanism to replace manual operation simultaneously, saved human cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1, the paper feed mechanism of the utility model embodiment comprises paper platform 1, the paper receiving device 2 that has conveyer mechanism 21 of depositing paper and is arranged at the conveying arrangement 3 that is transported to said paper receiving device 2 between said paper platform 1 and the paper receiving device 2 and with said paper from said paper platform 1.
Said paper platform 1 and paper receiving device 2 two ends that are laid in separated by a distance; Above between paper platform 1 and the paper receiving device 2, be provided with conveying arrangement 3, conveying arrangement 3 comprises draw frame machine 31, the said draw frame machine 31 of the drive reciprocating motion assembly 32 between said paper platform 1 and paper receiving device 2 that is used to adsorb paper.
Said draw frame machine 31 comprises some ventilation external members 312 that are positioned at conplane suction nozzle 311 and are tightly connected with said suction nozzle 311; Said suction nozzle 311 is processed for flexible resilient material; When suction nozzle 311 through supplying gas external member 312 when paper surface is air-breathing; Suction nozzle 311 preferably can be close to paper, but the air-flow that passes through that at high speed is firm like this holds the paper on the paper platform 1.
The induction control unit 4 that said motion assembly 32 comprises horicontal motion mechanism 321, is located at the lifting mechanism 322 that can move up and down on the said horicontal motion mechanism 321 and is used to control said horicontal motion mechanism 321 and lifting mechanism 322 moves, said draw frame machine 31 is arranged on the said lifting mechanism 322.
Said horicontal motion mechanism 321 comprises the horizontal guide rail 3211 that is arranged on said paper platform 1 and paper receiving device 2 tops, is slidingly installed in the horizontal slip mechanism 3212 on the said horizontal guide rail 3211; Said lifting mechanism 322 comprises the riser guide 3222 that is installed in the said horizontal slip mechanism 3212, is slidingly installed in the up-down slide mechanism 3221 on the said riser guide 3222; Said induction control unit 4 comprises that being arranged on said horicontal motion mechanism 3212 next doors is used to control the optical pickocff 42 of said horicontal motion mechanism 321 motions and is arranged on the pressure sensor 41 that is used to control said lifting mechanism 322 motions on the said draw frame machine 31.
The principle of work of the paper feed mechanism of following brief description the utility model embodiment: the upper table surface at said paper platform 1 has been stacked paper; Conveying arrangement 3 at first works in reference position; Make suction nozzle 311 touch paper; The ventilation external member 312 that is arranged on the draw frame machine 31 is air-breathing to paper surface through suction nozzle 311; Thereby suction nozzle 311 can hold first paper that pile up paper platform 1 top; Lifting mechanism 322 begins to do upward movement through up-down slide mechanism 3221 along riser guide 3222, and lifting mechanism 322 drives draw frame machines 31 and makees first paper that upward movement makes simultaneously and separate with paper platform 1 in this process, when lifting mechanism 322 moves to certain position, stops upward movement; Because the induction control action of optical pickocff 42; Horicontal motion mechanism 321 drive lifting mechanisms 322 along horizontal rail 3211 move to the corresponding cohesive position in paper receiving device 2 positions after stop motion, ventilate that external member 312 stops suction this moment and through suction nozzle 311 to the air blowing of first paper surface, first paper is blown on the paper receiving device 2 and then carries out next step transmission of paper; Horicontal motion mechanism 321 drives lifting mechanisms 322 and moves to reference position along horizontal rail 3211 subsequently, thereby lifting mechanism 322 drops to and the above-mentioned action that circulates of paper platform 1 top certain position.In above-mentioned defeated paper process; Control paper transfer continuously through the height between pressure sensor 41 control suction nozzles 311 and paper platform 1 upper table surface with through optical pickocff 42; Repeat said process successively and send a paper, thereby the automation that realizes defeated paper process is controlled.
Need to prove; The number of said suction nozzle 311 and position can be set according to actual conditions; For example can around paper edge rule of thumb value array be laid in the ventilation external member 312 on, can hold the paper on the paper platform 1 through air-flow more fast, stably like this.
Preferable; Said conveyer mechanism 21 can be provided with smooth surface and outward-dipping swash plate along the direction of transfer both sides; When paper when suction nozzle 311 breaks away from; Paper edge drops on and slides between the swash plate of both sides on the paper receiving device 2, can guarantee the smooth unification of paper receiving device 2 conveyance of sheets like this, reduces quality risk; Perhaps said paper receiving device 2 is manipulator mechanisms, and the mode of motion of manipulator is versatile and flexible, makes that the transmission of paper is accurate more, efficient.
As a kind of embodiment, paper can also transmit through pinch mechanism, and is not limited only to above-mentioned draw frame machine 31.
The above is the specific embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
