Definitions
- Aligning means consist of a stop engaging the leading edges of the sheets to be laminated as same are fed toward a pressure roller, said stop being moved by said sheets in response to the feeding movement of the sheets themselves toward said roller. Upon reaching said roller the stop is moved downwardly by the roller to a point below the plane of said sheets virtually simultaneously with the commencement of the pressure applying operation by the pressure roller onto said sheets. The stop is then returned to a point of beginning by any convenient means. As soon as it passes beyond the trailing edges of the sheets being laminated it returns to its normal position and is ready for engagement by and guiding of the next following set of sheets to be laminated.
- the invention relates to a method for aligning sheets to be laminated, particularly sets thereof consisting of a base and a lining, to the pressure roller on a sheet laminating machine.
- the sheets which consist for example of cardboard, corrugated paper or the like are guided on conveyor belts to the press roller.
- the lining which consists of cardboard, paper or the like, is placed on said sheet and the sheet and/ or lining is provided with an adhesive substance. It is important that the lining and sheet lie exactly one on top of the other since otherwise an after-treatment is required which usually involves cutting with a consequent loss of material.
- the reference for this laying of the one sheet in register on top of the other is obtained at the sheet edge.
- both sheets are in prior practice brought to rest against a stop and are then fed in superposed condition to the press roller.
- a slight pressing may take place at the edge so that the parts do not move against one another.
- These devices have the disadvantage that the cardboard sheets are stopped at the stop and must then be started again. If no prepressing takes place, then on the way to the press roller, in particular at the starting of the movement, there is danger of a misalignment occurring.
- this requires an additional device on the sheet laminating machine.
- the purpose of the invention is to feed the sheets which are to be united to the sheet laminating machine by means of pressing to the pressure roller in a manner in which they are caused to fit against one another.
- a sheet laminating machine which is characterized in that the stop is arranged alongside of a conveyor belt, or between the parts of a divided conveyor belt, on a slide rail extending in the direction of movement of the conveyor belt and has means for its return from a position behind the press roller to a position in front of the press roller.
- FIG. 1 is a longitudinal cross-sectional view of the feed portion to the press roller of a sheet laminating machine and FIG. 2 is a cross section of the conveyor belt along the line 11-11 of FIG. 1.
- the perforated conveyor belt 1 has two parts and slides over vacuum channels 2 underneath the press roller 3.
- the stop 4 is provided between the channels 2, said stop being tiltably positioned on the shaft 5 and the shaft itself is slidingly supported in the rail 6.
- the feeding of the lining 7 is guided by means 8.
- the draw-cord 9 is connected to the shaft 5, is placed over the roller 10 and carries the weight 11.
- the sheet 12 which is to be laminated is placed in position and is pulled with said belt by the vacuum acting through the perforations of the belt and any slipping is thereby prevented.
- the sheet abuts at its front edge the stop 4 which projects from below to a plane above the plane of the belt and causes the stop to move leftwardly with the leftward movement of the sheet and belt.
- the lining 7 is now placed onto the sheet 12 from above and fed in such a manner that its edge also abuts the stop 4, the same being accomplished easily and assuming an exactly fitting abutment of the front edges.
- the moistening or coating system for the adhesive is identified by the numeral 13.
- the adhesive can be applied as desired onto the lining or onto the sheet or both.
- the stop moving with said belt remains continuously at the front edges of both the sheet 12 and the lining 7.
- the entire set now slides underneath the press roller 3 whereby said roller first presses the stop 4 downwardly so that it pivots around its shaft 5.
- the sheet reaches the zone of the press roller 3 and the desired laminating pressure is applied.
- the sheet is thus guided by the stop up to the last moment.
- the stop pivots immediately.
- the stop is caused to pivot only when it contacts the stationary bolt 14 with its leading edge, moves to a level below the sheet (dash-dotted position of stop 4).
- the stop is then returned to the right to the starting position by the weight. Under the urging of the tension spring 15, the stop returns to its upright position as soon as the sheet 12 is no longer above same on the conveyor belt 1.
- the machine is then ready to receive the next sheet.
- the stop is tapered at 16 on its leading edge.
- ⁇ A suitable spring can be provided in place of the weight 11 and, in the same manner, the spring 15 can be replaced by a weight.
- several stops can be provided which are then arranged on both sides of the conveyor belt or in corresponding spaces between belt sections.
- the unit makes it possible to feed sheet and lining components to the press roller with their front edges in exact alignment and without stopping of same during such feeding. Also no special device is required to remove the stop since this is done directly by the press roller itself immediately as the pressing commences.
- a gripping device which takes the stop with it can be arranged on the conveyor belt for very light sheets which have an easily damagable front edge and are to be laminated.
- the sheets first abut the standing stop and then slide on the belt together with the stop to the press roller.
- the belt in this instance does not run over a vacuum box.
- the stationary trip 14 can be constructed as an electric switch which is connected to a magnet arranged below the stop. As soon as the switch is operated through contact with the stop, the magnet is energized and the stop is caused to pivot as before and comes to rest with its top below the conveyor belt plane so that the stop can return to the point A.
- a known sheet control apparatus for example a photocell 17, is desirably arranged near the lining feed, and electrically connected to a magnet 18.
- the magnet 18 remains energized.
- the magnet With its magnetic field, retains the weight in its normal position 11' so that the stop will not be moved by the sheet 12 until a lining, ready to be sent off, is present.
- an alignment apparatus comprising:
- stop means mounted on said track means for movement therealong between said starting position and said press roller means and including aligning means projecting into the path of said conveyor means and adapted to engage the leading edge of said sheets to be laminated for alignment thereof, said alignment being maintained from said starting position up to and until said leading edge is engaged by said press roller means;
- trip means for moving said aligning means out of engagement with said leading edge of said sheets to be laminated when said leading edge is engaged by said press roller means.
- stop means comprises shaft means supported for longitudinal movement along said track means and a stop, a portion of which is pivotally secured to said shaft means and having an aligning portion engaging said leading edge and pivotal about the axis of said shaft means out 4 of the path of said leading edge when said aligning means engages said press roller means.
- said trip means comprises a stationary bar positioned between said track means and said conveyor means and in the path of said aligning portion of said stop to effect said pivoting of said aligning portion out of the path of said leading edge.
- said conveyor means comprises a pair of side-by-side conveyors having a space therebetween and means for gripping one of the sheets to be laminated to prevent same from slipping relative thereto and at least one conveyor for feeding a liner to said starting position;
- said aligning portion of said stop extends upwardly from said shaft means between said pair of conveyors to a position of engagement with said leading edge of each of said sheets to be laminated for alignment thereof.
- said trip means includes return means connected to said stop means for yielding to the movement of said stop means when said aligning means is engaged by said leading edge of said sheets to be laminated so that when said aligning means is moved out of said path of said leading edge, said stop means will move back along said track means by said return means to said starting position.
- said return means comprises a pulley positioned adjacent said starting position a cable secured at one end to said stop means and extending over said pulley and a weight freely hanging from said pulley, said weight being moved vertically in response to said movement of said stop means to thereby elfect a return of said stop means to said starting position when said aligning means is moved out of engagement of said leading edge.
- A11 alignment apparatus including a magnet positioned below said weight and switching means responsive to the presence of a liner at said starting position for controlling the energizing of said magnet to permit said stop means to move along said track means only when a liner is present at said starting position.
- said trip means includes means for moving said aligning means out of the path of movement of said leading edge approximately simultaneously when said leading edge is engaged by said press roller means.
