Description
~zs~
The invention relates to an aligning device for boards~ having stops ~hich rest against the board edges pointed in the direction of transport of the boards.
- Before carr;ers, such as, for exampLe, printed circui~ boards, multi-layer laminations, metal plates or substrates with metal layers vapor-deposited andlor glued on both sides are laminated with a photo-resist film, it is necessary to align the carrier, transported on a guide track, so ~hat i~s edges are parallel, to allow the photo-resist film drawn off from supply rolls to be laminated on to the carrier so that they coinc;de exa G tly.
Laminating devices are known from pùblished European Patent Applications 0,040,84Z, o,n40,843 and 0,a41,642, and in these a substrate or a carrier is laminated on both s;des with a dry res~st under applied pressure. The dry resist for the partlcular side o~F
the carrier, for example a printed circu;t board, to be laminated is drawn off from a supply roll and supplied to a pair of laminating rollers, through whose nip run the two dry-resist films and the carrier located between them.
U.S. Patent 4,214,936 relates to a laminating apparatus in which horizontally transported boards, which are moved forwards continuously and contact-heated, are laminated on both s;des, the peripheral speed of the laminating rollers being greater than the feed speed of the boards. As soon as a sensor detects the rear edge of the preheated board shortly before it ~ 3û enters the nip between the laminating rollers, the ; latter are stopped only after a certain delay time allowing the rear edge of the board to pass ~hrough the laminating nip. When the front edge of the following board is detected, the laminating rollers s~art to rotate again and the board which has entered the nip is lamin-ated. This operation is repeated for each ne~ board, and a uniform distance between the individual laminated boards is maintained after the nip, when the boards ., ~
supplied to the laminating apparatus are from the outset at a uniform distance from one another, or when the boards run through the laminating apparatus at uniform intervals of time. This results in a continuous strip consisting of two dry-resist layers, between which the boards are enclosed at equal distances from one another.
In the known laminating apparatuses, the boards~
after passing through a cleaning device, are aligned in the direction of transport by means of a pair of align-1û ing rollers, one roller of each pair resting against oneside edge of the board. These aligning rollers are adjusted to a specific width of the boards, so that, ~hen the size of the boards is changed, the distance between the aligning rollers has to be readjusted for the changed board width, and this is time-consuming. Alignment of the boards by means of aligning rollers may be su~icient when the board ~5 transported vertically, since the board's own weight additionally assists vertical align-ment, but it is generally inadequate when the board is transported horizontally, since the point contact between the board and the aligning rollers is not sufficient to align the board in its direction of transport.
The object of the invention is to provide an al;gning device for boards, which adjusts itself auto-2S matically to different board ~idths and by means of which the boards are aligned in their direction of transport with a high degree of accuracy and over a longer distance.
This object is achieved, according to -the inven-tion, because the aligning device consists of two elon- -gate d ngular stops parallel to one ano~her and fastened to guides, which are displaceable along a guide rod extending transversely to the direction of transport of the boards, and of a motor-driven revolving endless chain to which the guides are connected.
In an embodimen~ of the invention, the guide rod is mounted at its ends in fastenings, a chain wheel is arranged on a side face of each fastening, and the chain is gu;ded endlessly round the chain wheels. Appropriately, 20731-~97 one guide is connected to the upper strand and the other guide to the lower strand of the chain, and the upper and lower strands of the chain run horizontally and parallel to the guide rod.
In accordance with the invention there is provided an aligning device for centrally aligning objects resting on a support by means of stops which rest against the lateral edges of the objects and are fastened to guides which, via a motor-driven chain endlessly revolving about two chain wheels one of which is arranged on either chain end, are displaceable above the support, in the direction of a guide device which extends in the direction of alignment and is supported by two stationary fastenings which ~re provided a.t the two lateral ends of the support and also carry the chain wheels, whereby one guide is connected to the upper strand of the chain and the other guide is connected to the lower strand of the chain, characterized in that said guide device is designed as a guide rod which extends perpendicularly to the path of a roller conveyor which constitutes the support and continuously advances the objects, that each of the two chain wheels is fastened to one of those faces of each fastening, which e~tend parallel to the guide rod, and that each of the two stops which extend parallel in respect of one another in the direction of transport is designed as an oblong angular member, the horizontal leg of which is fastened to the underside of the associated guide whereas the bottom edge of its downwardly directed vertical leg is in contact with the transport rollers of the roller conveyor and aligns the objects in the form of boards during transport.

The aligning device 1 illustrated in Figure 1 for a carrier, such as, for example, a mult:i-layer lamination or a board 16, which can be a printed circuit board or any other board metallized on two sides, is a component of a laminating apparatus (not shown), in which a photo-resist film is laminated on -to both sides of the carrier.

~2sæs~ ' - 3a A further advantageous embodiment of the invenkion emerges from the features of patent claims 4 to 8.
The invention is explained in more detail below with reference to an exemplary embodiment illustrated in the drawing.
In the draw~ng:
Figure 1 shows a perspective view of an aligning device according to the invention, and Figure 2 shows a diagrammatic representation of the aligning device according to Figure 1.
The aligning device 1 illustrated in Figure 1 for a carrier, such as, for example, a mult:i-layer lamination or a board 16, which can be a printed circuit board or any other board metallized on two sides, is a component of a laminating apparatus (not shown), in which a photo-resist film is laminated on -to both sides of the carrier. Where multi-layer laminations are concerned, alignment is carried out, for example, by means of proximity switches which make the stops move slowly nearer to the longitudina] edges of the multi-layer laminations for the purpose of the alignment operation. ~he aligning device 1 is arranged above a roller conveyor 14, along which the board 16 is trans-ported~ the horizontal roller conveyor 14 transporting the board 16 in the direction of the arrow D to a laminating station (not shown~. To guarantee that the board 16 is drawn accurately and in a straight line into the laminating station nip limited by two laminating rollers, it is necessary to align each board 16 along its longitudinal edges. For this purpose the aligning device 1 ~25~
- 3b -possesses two stops 7 and 8 parallel to one another, which extend in the direc-tion of the longitudinal edges of the board 16 and which are, for example, of angular design. The stops 7 and 8 touch the transport rollers ~,2522~
2 of the roller conveyor 14 at right angles by means of their bottom edges and are displaceable horizon-tally in the direction of the double arrows A, B.
~ Furthermore, the aligning device 1 includes two guides 12 and 13 which are displaceable along a guide rod 11 extending transversely to the direction of transport D
of the board 16. The stops 7 and ~ are fastened to the guides lZ and 13 respectively. The guides 12 and 13 are connected to a motor-driven revolving endless chain 5. One guide 12 is connected to the upper strand and the other guide 13 to the lo~er strand of the chain 5, the upper and lower strands o~ the chain 5 running horizontally and parallel to the guide rod 11. The guide rod 11 is mounted at its ends in cuboid fastenings 9, 9'. A chain wheel 10~ 10' is located on that side face of each fastening 9, 9' which is turned towards the board 16. The chain 5 is guided endlessly round the two chain wheels 10, 10' and is driven by a motor 15 nhich is preferably a linear motor. The connection between the chain 5 and the motor 15 is made by a chain clamp 4 tak;ng the form of an angle piece, one leg of which connects the motor 15 to the upper strand of the chain 5 and the other leg of which is fastened to one guide 12. A further chain clamp 6 joins the other guide 13 to the chain 5.
The motor 15 has an elongate form and extends parallel to and above a portion of the guide rod 11.
The motor 15 is connected to one cuboid fasten;ng 9, with which it forms a rightangle.
Figure Z shows a diagrammat1c view of the align-ing device 1. The linear motor 15 moves a piston in the direction of the double arrow C, and the piston can assume two extreme piston positions 3 and 3', in one 3 of which the piston rod is extended as far as possible ; 35 and in the other 3' of which the piston rod is retracted as far as possible. When the piston rod is extended, the two stops 7 and 8 move towards one another and, when the piston position 3 is reached, are at a minimum ~D ~
~ _ 5 _ 20731-897 dis-tance Lo from one another which is equal to the width of the smallest board to be aligned. The stops 7 and 8 then lie sym-metrically relative to a center plane 0-0' and are each at the distance Lo/2 ~rom this center plane.
The distance between the two piston positions and 3' is equal to a predetermined dimension X. When the piston rod is retracted from the piston position 3 into the piston position 3', ; the stops 7 and 8 move away from one another a total oE double the amount of the dimension X, so that the maximum distance between the two stops 7' and 8', which are represented by dot-and-dash lines, i9 equal to Lo -~ 2X.
:Cnstead Oe the lineax motor 15 and the piston, there can also be a pistonless pr~ssure cylinder, in which an engayement means for the stops can be displaced to and fro by means of com-pressed alr.
The aligning device 1 works as follows:
When a board 16 is transported along the roller conveyor 14 to the laminating station, the motor 15 is controlled according to the known size of the board 16, so that the piston rod is moved into a positi.on in which the distance between the two stops 7 and 8 is equal to or slightly greater than the width ofthe board 16.
The front edge of the board 16 comes up against a boar~ stop (not shown) pivoted into the path of the roller conveyor 14~ and at the same time the stops 7 and 8are moved up until they come up against the longitudinal edges of the board 16 and, if it is askew, thereby align it in the direction of transport D, so that the longitudinal edges point exactly in the direction of transport D. The board ~, ~2S~86 - 5a - 20731-897 stop is then lowered, and the board is grasped, for example by a board gripper, and conveyed to the laminating station.
.. ~

~ S22~
When boards of a different size are laminated, their known width is used to control the movement of the motor 15, ;n order to adjust the mutual distance between the stops 7 and ~ according to the new width. It is thus possible, merely by controlling the movement of the motor 15, to vary the distance between the two stops 7 and 8 between the dimensions LO and LO ~ 2X.
The al;gning device 1 can, of course~ operate without a board stop for the front edge of the board 16 and without a board gripper, since the stops 7 and 8 extending longitudinally, as soon as they have moved towards one another to a distance equal to the width of the board, align the skew board, located between them, in the direction of transport D and guide it along ;ts longitudinal edges until it is drawn into the laminating station, so that i~ is impossible for the board to become skew again.
In the embodiment illustrated, the stops 7 and 8 touch the transport rollers 2 by means of the;r bottom edges. In an embodiment which is not shown, but which has been put into pratice, the stops 7 and 8 are cut out in the form of segments of a circle at the locations of the transport rollers Z, their bottom edges extending slightly below the plane of movement of the boards.
~ Furthermore, the aligning device 1 includes two guides 12 and 13 which are displaceable along a guide rod 11 extending transversely to the direction of transport D
of the board 16. The stops 7 and ~ are fastened to the guides lZ and 13 respectively. The guides 12 and 13 are connected to a motor-driven revolving endless chain 5. One guide 12 is connected to the upper strand and the other guide 13 to the lo~er strand of the chain 5, the upper and lower strands o~ the chain 5 running horizontally and parallel to the guide rod 11. The guide rod 11 is mounted at its ends in cuboid fastenings 9, 9'. A chain wheel 10~ 10' is located on that side face of each fastening 9, 9' which is turned towards the board 16. The chain 5 is guided endlessly round the two chain wheels 10, 10' and is driven by a motor 15 nhich is preferably a linear motor. The connection between the chain 5 and the motor 15 is made by a chain clamp 4 tak;ng the form of an angle piece, one leg of which connects the motor 15 to the upper strand of the chain 5 and the other leg of which is fastened to one guide 12. A further chain clamp 6 joins the other guide 13 to the chain 5.
The motor 15 has an elongate form and extends parallel to and above a portion of the guide rod 11.
The motor 15 is connected to one cuboid fasten;ng 9, with which it forms a rightangle.
Figure Z shows a diagrammat1c view of the align-ing device 1. The linear motor 15 moves a piston in the direction of the double arrow C, and the piston can assume two extreme piston positions 3 and 3', in one 3 of which the piston rod is extended as far as possible ; 35 and in the other 3' of which the piston rod is retracted as far as possible.

The distance between the two piston positions and 3' is equal to a predetermined dimension X. When the piston rod is retracted from the piston position 3 into the piston position 3', ; the stops 7 and 8 move away from one another a total oE double the amount of the dimension X, so that the maximum distance between the two stops 7' and 8', which are represented by dot-and-dash lines, i9 equal to Lo -~ 2X.
