Detailed description of the invention
Referring to figs. 1 through Fig. 3, the paper feeder embodiment of the utility model folding machine is described further.
In prior art, the paper advance mechanism of folding machine makes paper enter on transport tape by absorption feeder absorption paper, absorption feeder is that a delivery roll 2 drives it to rotate by motor, and outside delivery roll 2, have many absorption air channels, popular says absorption air channel i.e. through hole, delivery roll 2 is hollow, be communicated with absorption air channel, connect Negative pressure machine simultaneously, Negative pressure machine produces negative pressure, extraneous air is passed through from absorption air channel, paper can be made paper surface can be made to be attached on delivery roll 2 when close absorption air channel simultaneously, and paper adsorption is conveyed on transport tape by rotating by delivery roll 2, enter folding machine to carry out processing the turnover of paper.This feed mechanism due to conveying paper slowly can reduce thus the absorption air channel on delivery roll 2 is reduced the absorption affinity of paper, thus make paper adsorption failure, simultaneously for the equipment having paper feeding to pitch, after paper tails off, paper fork is easily from slippage paper, causing cannot paper feeding, needs manually to carry out paper feeding.
As shown in Figure 1, 2, a kind of paper feeder of folding machine, comprises frame 1 and delivery roll 2, and described delivery roll 2 is rotationally connected in order to adsorb and to transmit paper with frame 1, also comprises pallet 3, elevating mechanism 4, drive circuit and cylinder 5; Described pallet 3 is provided with pressure sensor 7, and described pressure sensor 7 is in order to detect paper gravity and output detections signal; Described drive circuit is coupled to pressure sensor 7 in order to receive detection signal and output drive signal; Described cylinder 5 is coupled to drive circuit and provides elevating mechanism 4 driving force in order to receive drive singal and to respond drive singal; Described elevating mechanism 4 is connected with pallet 3 and moves up and down in order to driving tray 3.
Pallet 3 is for placing paper, and the pressure sensor 7 arranged under paper, pressure sensor 7 is resistance-strain chip pressure sensor 7, and model also can be adopted in the present embodiment to be the pressure sensor 7 of MPXM2010GS.Paper is placed on the difference that pressure sensor 7 will sense paper gravity, and the magnitude of voltage of the detection signal of the more much thicker output of paper will be larger.
Described elevating mechanism 4 comprises the first pole 41, second pole 42, the 3rd pole 43, the 4th pole 44, supporting seat 45 and drive unit; One end of described first pole 41 and the left surface a of supporting seat 45 hinged, the other end is provided with the first pulley and the edge slippage of left surface a in supporting plate; One end of described second pole 42 and the left surface a of supporting plate hinged, the other end is provided with the second pulley and the edge slippage of left surface a in supporting seat 45; One end of described 3rd pole 43 and the right flank b of supporting seat 45 hinged, the other end is provided with the 3rd pulley and the edge slippage of right flank b in supporting plate; One end of described 4th pole 44 and the right flank b of supporting plate hinged, the other end is provided with the 4th pulley and the edge slippage of right flank b in supporting seat 45; The central point of described first pole 41 and the second pole 42 is hinged, and the central point of described 3rd pole 43 and the 4th pole 44 is hinged; Be fixed with connecting rod 6 between described second pole 42 and the 4th pole 44, described cylinder 5 drives connecting rod 6 to move horizontally, thus driving tray 3 moves up and down.
For convenience of explanation, just the first pulley is referred to as pulley to the 4th pulley below.The driving shaft of cylinder 5 is connected with connecting rod 6 by hinged mode, connecting rod 6 is articulated with one end of the close pulley 46 of the second pole 42 and the 4th pole 44, time the driving shaft of cylinder 5 stretches out, pulley 46 bottom supporting seat 45 and pallet 3 on slide, thus the height of pallet 3 can be changed, pallet 3 can be declined, if time the driving shaft of cylinder 5 bounces back, pallet 3 will be made to increase, make pallet 3 just can be made to move up and down by the work of control cylinder 5, regulate the height of paper.Avoid and regulate manually.
As shown in Figure 3, drive circuit comprises reference cell A1, comparing unit A2 and performance element A3; Described reference cell A1 is coupled to comparing unit A2 in order to provide reference voltage; Described pressure sensor 7 is coupled to comparing unit A2 in order to provide detection signal; Described comparing unit A2 is coupled to performance element A3 in order to receive detection signal and output drive signal; Described performance element A3 is coupled to cylinder 5 in order to receive drive singal and to drive cylinder 5 to work.
Pressure sensor 7 detects that the paper put into is a lot, therefore with regard to output detections signal to comparing unit A2, comparing unit A2 is the first comparator U1, detection signal inputs to the in-phase input end of the first comparator U1 by changing voltage signal after resistance R3 into, by comparing with reference voltage, export high level, performance element A3 group will by normally closed relay K, NPN triode Q1, form with resistance R2, high level makes NPN triode Q1 conducting, the coil of normally closed relay K is obtained electric, the normally-closed contact of normally closed relay K is opened, make cylinder 5 must not electricity, the heavier supporting plate that makes of paper moves down by gravity, cylinder 5 must not be electric simultaneously, the driving shaft of cylinder 5 makes driving shaft the longest toward projecting forwardly to due to the driving force of elevating mechanism 4, paper remains on this height simultaneously.After paper tails off gradually, the magnitude of voltage that pressure sensor 7 exports will tail off, thus comparator U1 is exported for low level, make triode Q1 not conducting, make relay coil must not electricity, the normally-closed contact of relay is closed, cylinder 5 is energized work, the driving shaft of cylinder 5 is retracted, thus lifting pallet 3, make paper weight when being reduced to a certain degree, the driving shaft retraction of cylinder 5, make pallet 3 increase gradually, thus paper can be made can to continue near absorption air channel.
The second embodiment: driving mechanism can be spring, can be connected a spring between pallet 3 with supporting seat 45, can provide and recover, paper gravity is heavier, spring is just compressed, if the paper moon is light, so pallet 3 up will be stretched due to the elastic force of spring.Thus maintenance paper can always near the position in absorption air channel.
Preferably, described drive circuit also comprises alarm unit A4, described alarm unit A4 comprises the second comparator, active buzzer, the second triode and the 4th resistance, the in-phase input end input of described second comparator has reference voltage, inverting input is coupled to pressure sensor 7, and be coupled to the base stage of the second triode after output series connection the 4th resistance, the colelctor electrode of the second triode is coupled to active buzzer, the grounded emitter of the second triode, the other end of active buzzer couples power end.
When the gravity of paper is lower time, can export high level by the second comparator, make active buzzer alarm call, user can be known, and paper has not had soon, can add paper.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
