Detailed description of the invention
Below, this embodiment with the fixed component of novel hole plate print device is explained with reference to Fig. 1 (a) ~ Fig. 6.
The hole plate print device of the present utility model that Fig. 1 (a) ~ Fig. 1 (d) illustrates has printing cylinder 1 and comprises the pressing mechanism 21 of pressure roller 2, utilize and be wound with the printing cylinder 1 of version and pressure roller 2 and sandwich the paper that feeding comes, thus the image of version is transferred to paper.
As shown in Figure 4, pressing mechanism 21 comprises fulcrum shaft 3.Fulcrum shaft 3 is rectangular clava, is formed at parallel with pressure roller 2 and separates the position of certain intervals, utilizing the axle of connecting rod and pressure roller 2 to be connected.By the rotation of fulcrum shaft 3, pressure roller 2 is swung with being pressed against or leaving relative to printing cylinder 1.
As shown in Figure 2, in front of the operator of fulcrum shaft 3, the shape of cross section of the end 3a of side is formed as 2D shape, and it runs through the limiting holes 8a of fixed component 8 described later.
So-called 2D shape to refer to by two single D shapes combine and the shape that formed.Single D shape refers to and utilizes secant to intercept the anon-normal toroidal be made up of circular order portion and secant obtained circle.Therefore, 2D shape also can be understood as and utilizes two secants to intercept the circular shape obtained.Preferably two secants of parallel (comprising almost parallel).
The secant (corresponding to side 301,302) of two single D shapes shown in Figure 2 combines the end 3a of the rear 2D shape obtained abreast.
As shown in Fig. 1 (a), the other end 3b (pivot) being positioned at dorsal part of fulcrum shaft 3 is installed with rocking bar 57, this rocking bar 57 at one end side pallet 6 is relatively provided with hook 7, to be provided with the extension spring 5 for pulling rocking bar 57 to be pressed against to printing cylinder 1 to make pressure roller 2 across pivot in another side.
As shown in Figure 3, fixed component 8 is roughly rectangular metal sheet, have for insert for the end 3a of fulcrum shaft 3 and can confinement end 3a slewing area wherein limiting holes 8a and utilize not shown screw etc. to be installed on one or more installing hole 8b of organism frame (supporting mass).
In the top view of Fig. 3, limiting holes 8a have by across space, hole interference edges respect to one another 801,802, dodge the shape that limit 803,804 is formed by connecting.Wherein, the top be made up of interference edges 801 and extended line (in figure upper right side dotted line 805) thereof be roughly parallel to by interference edges 802 and extended line (in figure lower left side dotted line 806) thereof form following.This top, below and dodge formation accommodation section, the portion 8a1 of 803,804 envelopes in limit.This accommodation section 8a1 in wherein, and limits the rotation of end 3a to a direction (being illustrated as clockwise direction) of this fulcrum shaft 3 for the end 3a matched in clearance of aftermentioned fulcrum shaft 3 with interference edges 801,802.Relief portion 8a2,8a2 is defined with the part dodging 803,804 envelopes in limit respectively by upper right side dotted line 805, lower left side dotted line 806.This relief portion 8a2,8a2 allow clearance are matched with the rotation of end 3a to the predetermined angular of another direction (being illustrated as counterclockwise) of the fulcrum shaft 3 in the 8a1 of accommodation section.
Particularly, as shown in Figure 3, the contour shape of accommodation section 8a1 is larger a little than the periphery of the end 3a of fulcrum shaft 3, roughly rectangular shape, and it is for holding the end 3a of fulcrum shaft 3, but is rotated in Kong Zhongxiang mono-direction by interference edges 801,802 confinement end 3a.That is, in the way that end 3a turns clockwise in hole, interference edges 801,802 (face at place) can contact with the side 301,302 of end 3a and interfere the continuation rotation of end 3a (fulcrum shaft 3).
In addition, in the embodiments of figure 3, relief portion 8a2 is formed as the notch shape of general triangular, can be regarded as accommodation section 8a1 inner rim (namely interference edges 801,802, dotted line 805,806 and part dodge the inner rim that limit 803,804 forms) on the notch shape of dotted line 805,806 position opening, and continuous with accommodation section 8a1 phase via the opening portion of this dotted line 805,806 position.This relief portion 8a2 is used for allowing that end 3a rotates at Kong Zhongxiang other direction (in figure shown in arrow).That is, advancing along dodging limit 803,804 in two circular order portions 303,304 of end 3a, crosses dotted line 805,806 and while entering relief portion 8a2, fulcrum shaft 3 also have rotated predetermined angular counterclockwise.Then, due to the stop of interference edges 801,802, the further rotation entering two across corner of relief portion 8a2 of end 3a is restricted.Therefore, relief portion 8a2 provides and supplies the end 3a of fulcrum shaft 3 to dodge cushion space to a certain degree to one direction.
Before will carrying hole plate print device, such as unclamp pallet 6 to solenoid 66 power-off, pallet 6 unclamps hooking position, revolves turn around and guarantee that hook 7 arrives this hooking position by making printing cylinder, pallet 6 is mounted with hook 7 phase, thus guarantees to make pressure roller away from printing cylinder.In this case, fixed component 8 is plugged in the end 3a of the fulcrum shaft 3 that the organism frame of side in front of operator exposes.Particularly, when operator is to self side pull-out printing cylinder 1, namely the end 3a of fulcrum shaft 3 can be seen from the position of operator, the limiting holes 8a of fixed component 8 is set in the 2D shaped position of this end 3a, not shown screw etc. is utilized fixed component 8 to be fixed on organism frame via installing hole 8b, installment state as shown in Figure 5.Be configured to clearance fit relationship between the side 301,302 of the end 3a of fulcrum shaft 3 and the interference edges 801,802 of accommodation section 8a1, thus this fixed component 8 as aftermentioned prevent pallet 6 from breaking off relations with hook 7 after pressure roller swing and abut printing cylinder.Like this, operator can load and unload fixed component 8 in side, front, thus avoids dorsal part and go to operate for necessity of the locking component of anti-locking hook, and the shell that it also avoid dismounting dorsal part just can the trouble of operational lock component.
After hole plate print device is delivered to destination, the setting before bringing into use, to safeguard, as aforementioned, printing cylinder 1 be made to dally (rotation) one circle, guarantee the hook status of pallet 6 and hook 7.
Particularly, first, connect the main power source of hole plate print device, control panel shows the information that the printing cylinder 1 one that whether will dally encloses, and now operator presses the button that printing cylinder 1 sky is turned around, like this, no matter before idle running, whether there occurs unhook, after printing cylinder 1 sky turns around, pallet 6 and hook 7 are in hook status, and control panel display notifies the information that fixed component 8 can unload by operator.
So, before conveying hole plate print device, be by means of installing hole 8b, fixed component 8 is fixed on organism frame under the state do not broken off relations at pallet 6 and hook 7.Therefore, even if because collision etc. there occurs the situation of unhook in course of conveying, interference edges 801,802 due to the limiting holes 8a of fixed component 8 limits the rotation of fulcrum shaft 3, and therefore pressing mechanism 21 can not rotate to the direction of printing cylinder 1, thus pressure roller 2 can not contact with printing cylinder 1.
Before use hole plate print device carries out presswork, as above make after printing cylinder sky turns around according to instruction, be in pallet 6 mount with hook 7 phase and ensure that the state of pressure roller away from printing cylinder, now can unload not shown screw from installing hole 8b and fixed component 8 be unloaded from organism frame, utilize this screw that the fixed component 8 unloaded is installed on the temporary construction opening 10 such as shown in Fig. 5, prevent the fixed component 8 unloaded from losing.
If do not make printing cylinder 1 sky turn around before presswork, then hole plate print device may be in the state of unhook, if now directly unload fixed component 8, likely can there is pressing mechanism 21 and swing suddenly and cause pressure roller 2 to collide the situation of printing cylinder 1.
The mechanism turned around about printing cylinder 1 sky is briefly described.As shown in Fig. 1 (b), fulcrum shaft 3 forms mechanical linkage relation with printing cylinder 1 by mechanisms such as gears 9.Cam 4 and gear 9 are coaxially arranged.Along with the rotation of the gear 9 with printing cylinder 1 interlock, cam 4 rotates, and utilizes the projection of cam 4 to promote rocking bar 57 and swings, thus drive pressing mechanism 21 to rotate clockwise.Assuming that under the state of having thrown off pallet 6 at hook 7, the peripheral part of pushing pallet 6 makes pallet 6 retreat by hook 7, makes the top hook portion of hook 7 can again go up pallet 6, thus automatically recovers the hook status of pallet 6, hook 7.
On the other hand, if pallet 6 does not break off relations with hook 7, because pallet 6 has been in above-mentioned going-back position, therefore, even if printing cylinder 1 sky turns around, the projection of cam 4 can not produce the action that pallet 6 is retreated further, even if or pallet 6 to retreat also be retreat together with hook 7, thus also would not the hook status between pallet 6 and hook 7 to be had an impact.
As shown in Figure 4, the end 3a of fulcrum shaft 3 is 2D shape, and it runs through the limiting holes 8a of fixed component 8.Before printing cylinder 1 sky turns around, if broken off relations, then fulcrum shaft 3 will rotate along clockwise direction, and pressure roller 2 also will along with rotation.From the angle of relative motion, this is equivalent to pressing mechanism 21 in the diagram and keeps static, and fixed component 8 rotates along the counter clockwise direction shown in arrow.Now, the side 301,302 with end 3a is interfered by the interference edges 801,802 of fixed component 8.Because fixed component 8 is fixed on organism frame via screw etc., therefore, the further rotation along clockwise direction of fulcrum shaft 3 is also just limited.
Contact with interference edges 801,802 Local Phase of fixed component 8 respectively with the side 301,302 of end 3a owing to just existing based on above-mentioned matched in clearance when fixed component 8 being fixed on organism frame or arrange by the state contacted, therefore, even when fulcrum shaft 3 will be made to rotate along clockwise direction when occurring to break off relations, due to the restriction of the interference edges 801,802 of the limiting holes 8a of fixed component 8, fulcrum shaft 3 also can not rotate substantially, thus guarantees that pressure roller 2 and printing cylinder 1 can not come in contact because of unhook.
In addition, in the process that printing cylinder 1 sky turns around, due to the continuous action relation with printing cylinder 1, fulcrum shaft 3 can rotate very little angle along the counter clockwise direction in Fig. 4, thus make the side 301 of end 3a, the contiguous interference edges 801 of 302, the bight of 802 is away from interference edges 801, 802, and the side 301 of end 3a, the contiguous dotted line 805 of 302, dotted line 805 is then crossed in the bight of 806, 806 and to enter relief portion 8a2 (be in fact now circular order portion 303, 304 along dodging limit 803, 804 rotate, pressure roller 2 is rotated) towards the direction away from printing cylinder 1.
So, the design of relief portion 8a2, what ensure that printing cylinder 1 sky turns around carries out smoothly, thus ensure that pallet 6 mounts with hook 7 phase.
In addition, even above-mentioned dodge state under, fulcrum shaft 3 such as rotates along clockwise direction owing to breaking off relations between pallet 6 and hook 7 and returns (being in fact now along making pressure roller 2 rotate close to the direction of printing cylinder 1), in return course, due to the restriction of the accommodation section 8a1 of the limiting holes 8a of fixed component 8, after fulcrum shaft 3 only rotates a less angle, the side 301,302 of end 3a contacts interference edges 801,802 and cannot continue to rotate along Return-ing direction, therefore still can prevent pressure roller 2 from contacting with printing cylinder 1.
Afterwards, when normal presswork, utilize the solenoid 66 be such as energized to be pulled to by pallet 6 and make a concession position, make hook 7 depart from the constraint of pallet 6, utilize the effect of cam 4 make pressure roller 2 be pressed against printing cylinder 1 gradually and coordinate the rotation of printing cylinder 1 and carry out transfer printing.When having carried out presswork, needing conveying, remove above-mentionedly solenoidally retracting state, re-start the bonding operation of pallet 6, hook 7, prevent pressure roller 2 from contacting with printing cylinder 1.And, by installing fixed component 8 of the present utility model, can guarantee further in course of conveying, prevent pressure roller 2 from contacting with printing cylinder 1.
In addition, in the utility model, the shape of the accommodation section 8a1 of the limiting holes 8a of fixed component 8 is the 2D shape corresponding with the end 3a of fulcrum shaft 3, but is also not limited to this, also can be D shape, also can be other anon-normal toroidal of non-D shape.Correspondingly, the cross sectional shape of the end 3a of fulcrum shaft 3 is by matched in clearance then can be restricted the shape of rotation and can rotate backward certain angle in relief portion 8a2 but then rotate backward the combination of shapes that can be restricted and form in the 8a1 of this accommodation section.
In addition, in the utility model, fixed component 8 is installed on the end 3a of fulcrum shaft 3, but be also not limited to this, also the position of the non-end of fulcrum shaft can be installed on, such as make the limiting holes 8a of fixed component 8 be formed as the roughly U-shape of a side opening, the position of the non-end of fulcrum shaft can be inserted into, limit the rotation of fulcrum shaft.
In addition, a variation of the fixed component 8 gone out as shown in Figure 6.This fixed component 8 is provided with limiting holes 8a and installing hole 8b.The outer peripheral face of fulcrum shaft 3 is given prominence to and is formed with key 305, fulcrum shaft 3 is installed in the limiting holes 8a had with its roughly correspondingly-shaped, the main part matched in clearance of fulcrum shaft 3 is in poroid accommodation section 8a1, key 305 enters in the relief portion 8a2 of notch-like, so, two interference edges 801,802 of relief portion 8a2 determine the rotational angle α of fulcrum shaft 3 in limiting holes 8a, and this angle is the amount of spin of the fulcrum shaft 3 corresponded to when above-mentioned printing cylinder 1 rotates a circle.
As mentioned above, the utility model utilizes present embodiment to record, but the discussion of the part of the disclosure and accompanying drawing do not limit the utility model.According to the disclosure, those skilled in the art should be able to be specified each and be replaced embodiment, embodiment and application technology.Therefore, technical scope of the present utility model is only determined according to the specific item of utility model in the scope of established right requirement.
