The top material loading conveyer device 10 of present embodiment is provided with a plurality of belt pulleys on framework 20, make feeding belt 17 above hanging over (Fig. 4, Fig. 5).Framework 20 is to constitute by being fixed on fixed frame 21 on the frame FS and the slide mechanism by horizontal direction is combined on fixed frame 21 sliding frame 22.
Fixed configurations has 1 couple of sprocket wheel SR1, SR2 on the horizontal direction in fixed frame 21, is provided with simultaneously to drive on a sprocket wheel SR2 to use sprocket wheel SR3.Slide mechanism is provided with slide block 23 between 1 couple of sprocket wheel SR1, SR2, slide block 23 is fixed on the sliding frame 22.Connecting around hanging over 1 pair of chain CH two ends between sprocket wheel SR1, the SR2 on the slide block 23.Therefore, to driving with behind the sprocket wheel SR3 input power, sliding frame 22 can slide in 23 actuating ranges of the slide block between 1 couple of sprocket wheel SR1, SR2 in the horizontal direction.This moment, the direction of action of sliding frame 22 was along the centre line C L direction (Fig. 3) that connects front end belt pulley 11 and rear end belt pulley 15.Wherein the driving of slide block 23 also can utilize snap bolt conveying mechanism etc.
Drive pulley 13 and rear end belt pulley 15 are installed on the fixed frame 21 and are configured in mute pulley 14 between described two belt pulleys.On the other hand, front end belt pulley 11 and idler 12 are installed on sliding frame 22.Drive pulley 13 is in the above in the material loading conveyer device 10, utilizes the drive pulley of drive source by power-transmission system, and drive pulley 13 is pressed the hour hands direction and rotated (Fig. 3).In addition, rear end belt pulley 15 is driven skin 15 belt wheels that are configured in material loading conveyer device 10 rear ends.Idler 12 is to be used to make the tension force of feeding belt 17 to keep certain belt pulley, has tension force increase that makes feeding belt 17 or the adjustment screw that reduces on its mounting portion.
Feeding belt 17 to drive pulley 13, arrives rear end belt pulley 15 through mute pulley 14, by the path wraparound (Fig. 3, Fig. 4) from rear end belt pulley 15 to front end belt pulley 11 from front end belt pulley 11 process idlers 12 again.Therefore, the feeding belt 17 between front end belt pulley 11 and rear end belt pulley 15 becomes linear, in order between front end belt pulley 11 and rear end belt pulley 15 feeding belt 17 to be remained on the straight line, has been arranged side by side 5 auxiliary belt wheels 16.In addition, idler 12 is configured to make front end belt 11 and drives feeding belt 17 state that stretches of the direction of belt pulley 15 to the back-end between the belt 13.
At this, the top material loading conveyer device 10 with present embodiment is used in pairs, material loading conveyer device 50 carries out simple declaration below individual workpiece of the back side one side drive W1.Following material loading conveyer device 50 has drive pulley 52, front end belt pulley 51, rear end belt pulley 54 and the idler 53 that is installed on the single fixed frame 55, feeding belt 56 returns through the path wraparound of idler 53 to drive pulley 52 according to passing through front end belt pulleys 51 to rear end belt pulley 54 from drive pulley 52 again.At this moment, feeding belt 56 shape that between front end belt pulley 51 and rear end belt pulley 54, is in line, drive pulley 52 rotates counter clockwise.And top with following material loading conveyer device 10,50 is combined into both feeding belts 17,56 to be drawn into rectilinear part relative up and down, sets the corresponding clearance G 1 of thickness (Fig. 3) with individual workpiece W1 between both feeding belts 17,56.
The top material loading conveyer device 10 of above-mentioned embodiment carries out following coordination with following material loading conveyer device 50 in the system punch-out equipment.
More than of individual workpiece W1 that are installed on the paper feeding part S1 send downstream, send (Fig. 1) with the transporting velocity of regulation to printing S2 by 1 couple of feeding roller r2.Wherein the condition of She Dinging is that individual workpiece W1 carries out 2 look printings, only uses 4 printing unit P1 ... 2 of beginning of P4,2 empty mistakes of back.Wherein said in this manual " the empty mistake " is meant and utilizes existing well-known elevating method, make printing cylinder R1 carry out lifting moving (moving up and down), uses under the situation by printing cylinder R1.Therefore, the printing cylinder R1 of printing unit P1, P2 that the front is 2 and hold-down roll R2 are close to and keep and the corresponding gap of individual workpiece W1 thickness, the printing cylinder R1 of next 2 printing unit P3, P4 falls back on the position above the hold-down roll R2, leaves hold-down roll R2.
Be clamped between the top material loading conveyer device 10 that is arranged between the initial printing unit P1 of paper feeding part S1 and printing S2 and the following material loading conveyer device 50 through individual workpiece W1 of feeding roller r2 and carry.And individual workpiece W1 that arrives initial printing unit P1 is clamped in the printing of stipulating between printing cylinder R1 and the hold-down roll R2, utilizes printing cylinder R1 and hold-down roll R2 to force to be transported between the top material loading conveyer device 10 and following material loading conveyer device 50 of follow-up downstream one side simultaneously.The downstream one side material loading conveyer device 10,50 that obtains individual workpiece W1 also is identical content with the 2nd printing unit P2, repeats this action.
At this moment, the top material loading conveyer device 10 that is connected on downstream one side of the 2nd printing unit P2 back utilizes the sliding action of described sliding frame 22, makes front end belt pulley 11 to the rear end change location standby near material loading conveyer device 10,50 above follow-up.And above this moment the front end belt pulley 11 of material loading conveyer device 10 arrive the hold-down roll R2 that makes among empty the 3rd the printing unit P3 that crosses of individual workpiece W1 directly over position (Fig. 1, Fig. 3).
Wherein, because the idler 12 in the top material loading conveyer device 10 is installed on the same sliding frame 22 with front end belt pulley 11, idler 12 carries out equivalent with front end belt pulley 11 to equidirectional and moves.But the change in location of front end belt pulley 11 is opposite with the draw direction of feeding belt at this moment, and the change in location of idler 12 is directions (Fig. 3) of lax feeding belt.Therefore the tension force with the change in location feeding belt 17 of front end belt pulley 11 is constant.This just means the tension variation that need not take feeding belt 17 into account, can utilize the simple operations that only changes sliding frame 22 positions to change the position of front end belt pulley 11 separately.
The peripheral speed of the feeding belt 17 in the top in addition material loading conveyer device 10 is constant in the mobile front and back of front end belt pulley 11, and also constant in moving.Because the peripheral speed of feeding belt 17 is irrelevant with the interval of front end belt pulley 11 and rear end belt pulley 15 by the diameter and the revolution decision of drive pulley 13.
Any position is determined in general in addition view front end belt pulley 11 and the rear end belt pulley 15, even another belt pulley is in moving, the peripheral speed of feeding belt 17 is also constant.Even this is also from making any one belt pulley move that the revolution of another belt pulley is also constant to be come as can be seen.And on present embodiment, in the material loading conveyer device 10, make the belt pulley 15 fixing front end belt pulleys 11 that also only make in rear end move this effect of realization.Even therefore, also carry individual workpiece W1 with the speed of setting in the position of individual workpiece W1 by change front end belt pulley 11 in the process.This means that not stopping to make punch-out equipment can carry out the action of mobile front end belt pulley 11.
Have under the situation of mobile simultaneously front end belt pulley 11 and rear end belt pulley 15, the feeding belt 17 of La Shening changes with respect to the relative peripheral speed of individual workpiece W1 betwixt again.Because with respect to individual workpiece W1, the driving that applies will add the speed when front end belt pulley 11 and rear end belt pulley 15 are mobile simultaneously on the peripheral speed of feeding belt 17.
Drive the front end belt pulley 11 in the top material loading conveyer device 10 directly over the turnover hold-down roll R2, make by feeding belt 17 and hold-down roll R2 between individual workpiece of clamping W1, downstream transport.Printing cylinder R1 when just front end belt pulley 11 can replace printing action, W1 is pressed on the hold-down roll R2 individual workpiece.Its as a result individual workpiece W1 be driven by feeding belt 17 and hold-down roll R2, prevent the position of individual workpiece W1 by when printing and the position skew when carrying.Its result can prevent to print the changing of the relative positions under the situation of using follow-up printing unit P3, P4.The degree that has the interval L1 between the rear end belt pulley 15 of the front end belt pulley 11 that enters when action and follow-up top material loading conveyer device 10 to set again is arbitrarily.Generally under the thin situation of individual workpiece W1 that uses, wish to set narrower (Fig. 3).Because by individual workpiece W1 on the hold-down roll R2 arrive follow-up above before the material loading conveyer device 10, be to lean on the intensity in the middle of individual workpiece W1 to drive pushing under the state of conveying.

It is that circular motion is done at the center with counter pulley 19 that the material loading conveyer device 30 of this mode makes front end belt pulley 11, just by making front end one side feeding belt 18 lift and put down action, material loading conveyer device 30 front positions are changed, from 2 positions, select 1.Be exactly specifically when printing unit P2 prints action, to make front end one side feeding belt 18 lift action, make the front position of material loading conveyer device 30 reality retreat into the position of counter pulley 19 like this.Printing unit P2 falls printing cylinder R1 at this moment, can print (Fig. 7).
Under the situation of not using printing unit P2, its printing cylinder R1 promotes on the other hand, keeps holding state.The material loading conveyer device puts down front end one side feeding belt 18 30 this moments, is positioned at rear end one side feeding belt 17 in alignment side by side.Therefore material loading conveyer device 30 front positions pass in and out follow-up material loading conveyer device 30,50 1 sides (Fig. 8) to be equivalent to the interval of front end belt pulley 11 and counter pulley 19.Just put down about 120 degree, can correctly pass in and out the delivery position of individual workpiece W1.With the above-mentioned structure that counter pulley 19 is clipped in the middle, even front end one side feeding belt 18 is put down about 120 and spends from lifting state, the peripheral speed of feeding belt and also can remain unchanged with respect to the relation of individual workpiece.Have again in the material loading conveyer device 30 of this mode, utilize the interval of adjusting front end belt pulley 11 and counter pulley 19, can freely set the turnover amount and the amount of retreating of material loading conveyer device 30.
The wherein action of lifting and putting down of front end one side feeding belt 18, for example its structure can be that the cylinder that utilizes fixing framework one side that is installed in rear end one side feeding belt 17 is handled the framework that (not having expression among the figure) installs front end belt pulley 11 and counter pulley 19, in addition, also can be by the brake of the axle braking that makes counter pulley 19 is set on the framework of front end one side feeding belt 18, the structure of utilizing the counter-force when making the axle braking to lift waits and realizes.
In addition in the present embodiment, printing cylinder R1 is moved up and down on hold-down roll R2, the situation of material loading conveyer device 10 turnover actions is illustrated, and the state that the present invention also goes on hold-down roll R2 is placed moves up and down printing cylinder R1, hold-down roll R2 in its lower section, makes the situation of material loading conveyer device 50 turnover with above-mentioned material loading conveyer device 10 structures on the position after this moves.Material loading conveyer device of the present invention is the conveying device that is suitable for individual workpiece, the situation that the position that arrives for the distance of carrying or individual workpiece need increase or reduce can be widely used in the printing of individual workpiece except corrugated board system punch-out equipment.
The material loading conveyer device of individual workpiece printing of the present invention does not make the rear end belt pulley in the material loading conveyer device move, the front end belt pulley that only makes it is near the back operation material loading conveyer device that the printing unit is clipped in the middle and is provided with, the feeding belt peripheral speed that just can make the material loading conveyer device moves the front end belt pulley when keeping certain with respect to the relation of individual workpiece, so when the printing unit that the galley and the replacing of exchange printing cylinder are used, need not stop to make punch-out equipment, even do not stopping to make under the situation of punch-out equipment in addition, also can prevent the printing changing of the relative positions that back operation printing unit produces effectively.
