Definitions

• the invention relates to a method for affixing supplements to moving objects, wherein a stack of supplements is placed in a holder, after which supplements are taken from said stack one at a time and adhered to a passing object by means of an adhesive.
• the supplements can be adhered to any object provided that such object has an appropriate surface for receiving the supplement.
• the objects can be packages or containers of a product, which packages or containers are moved by a conveyor for example.
• the objects can be news papers or quires. When hereinafter quires are mentioned, any other object is also be meant.
• quires should be given a wide interpretation. It includes magazines as well as parts of magazines and brochures and any other sheet of paper or other material that is subjected to a processing step wherein a number of copies are moved in a continuous row.
• Supplements of this kind are usually affixed to a page of the quire by means of an adhesive during the selecting and putting together of the quires.
• the supplements are thereby stacked in a holder and removed from the holder one at a time, followed by the application of glue, after which the supplement is affixed to the page in question.
• a method of this kind is usually carried out at a very high speed, so that it is important that the affixation of the supplement takes place faultlessly, without any malfunctions.
• a brief malfunction may have major consequences with regard to the progress of the process of putting together magazines, for example.
• the object of the invention is to provide a method for affixing supplements to objects such as pages of quires, wherein the supplements can be placed in the holder in a form which enables easy handling, and wherein the supplements can be affixed to the respective objects at a very high speed and in a very reliable manner.
• a film of adhesive which is capable of rebonding, is according to the invention applied to at least part of one side of each supplement .
• the supplements can be separated from the stack one at a time by engaging a respective supplement at a place where no adhesive is present, after which the supplement is separated from the supplement being in contact therewith in the stack by moving the contacting surfaces of the supplements apart in a direction substantially perpendicularly to said surfaces, i.e. without shifting the supplements over each other.
• a coherent stack of supplements which is easy to handle and wherein the supplements are correctly positioned with respect to each other whilst maintaining said position can be obtained by applying an adhesive to the supplements before composing a stack of supplements.
• the supplements are prevented from shifting with respect to each other upon or after being placed in the holder.
• Another advantage of the use of an adhesive which is capable of rebonding is the fact that the supplement can subsequently be adhered to another object.
• An adhesive of this type which can be inseparably applied to a surface in a thin layer, possibly with the interposition of a coating, and which can be adhered to a surface, such as paper, in such a manner as to be capable of rebonding, that is, be used several times whilst retaining its bonding action, is known per se.
• An example is described in EP-A-0 276 557, and in the publications referred to therein.
• the surfaces of the supplements being in contact with each other are moved apart by blowing air between the supplements to be separated, in the direction of the adhesive present between said supplements.
• a plate-shaped separating element which is moved between the supplements, may be used for separating the supplements from each other, possibly in combination with the aforesaid blowing of air between the pages.
• a supplement is separated from a stack by pulling a part of said supplement away from the stack by means of a suction nozzle, after which said part is bent over and the bent-over part is subsequently engaged and moved in a direction away from the stack.
• a suction nozzle makes it possible to draw the supplement against a surface in a reliable manner.
• the suction nozzle may thereby be provided on a separating element, which rotates about an axis which extends substantially parallel to the supplements in the stack, which suction nozzle is provided on a sloping surface of said separating element, which surface extends obliquely relative to the radial plane, whereby said part of the supplement is pulled away from the stack as a result of said sloping surface moving along the surface of said supplement, whereby the supplement is sucked against said sloping surface.
• the suction nozzle is provided on the cylindrical surface of a rotating roller which rolls over the supplement of the stack that is to be separated, so that said part of the supplement is sucked against said cylindrical surface and is bent to conform with said surface.
• a second roller may thereby rotate against the former roller, so that the supplement is engaged and carried off as a result of the pinching action between the two rollers.
• the supplement consists of a container containing a liquid, such as a shampoo or other detergent to be removed from said container.
• the container may also contain other products, for example one or more samples of an object. Since the supplements present in the stack are provided with an adhesive, the contours of the supplements may differ from those of the holder, which is usually rectangular.
• the supplement consists of a sheet of paper with for example an advertising text or other message present thereon.
• An example of this is a supplement with a pre-printed telephone number, which can be detached from a magazine and which can subsequently be affixed to a telephone set. It is preferred to use an adhesive which bonds more strongly to the supplement, or to a coating provided on the supplement under said adhesive, than to the material of the quire, so that the page of the quire will remain undamaged, free from adhesive, after the supplement has been removed from said page.
• the invention furthermore relates to a device for affixing supplements to pages of quires comprising a holder, in which a stack of supplements can be placed, and means for separating supplements from the stack one at a time and affixing them to a page of a passing quire by means of an adhesive, wherein said means are designed such that a respective supplement is separated from the supplement being in contact therewith in the stack by moving the contacting surfaces of the supplements apart in a direction substantially perpendicularly to said surfaces .
• said means are provided with a blow nozzle for blowing air between surfaces of the supplements that are in contact with each other, in the direction of the adhesive present between said supplements.
• Said means may furthermore be provided with a plate-shaped separating element, which is capable of movement between the contacting surfaces of the supplements.
• Figures 1 and 2 show an embodiment provided with a blow nozzle
• Figures 3 and 4 show an embodiment provided with a plate-shaped separating element
• Figure 5 is a bottom view of a rotatable separating element
• Figures 6 and 7 are sectional views along lines VI-VI and VII-VII respectively in Figure 5;
• Figure 8 shows another device provided with a rotatable cylindrical roller
• FIGs 9-11 show the operation of the device according to Figure 8.
• the device comprises a holder 1 containing a number of supplements 2.
• Supplements 2 form a stack and are all provided with a film of glue 3 covering part of the surface area on one side, which film of glue is illustrated in thin lines in the Figures.
• Film of glue 3 is composed to bond inseparably to a supplement on one side, with the interposition of a coating, for example, and to be affixed on the other side to the surface of an adjacent supplement, in such a manner that rebonding is possible.
• Said film of glue 3 is present on the upwardly facing side of supplements 2.
• An opening 4 is present near the bottom side of holder 1, through which opening the lowermost supplement of the stack of supplements 2 can be engaged.
• Said engaging of the lowermost supplement 2 takes place by means of clamping elements 5, which are mounted on a rotatable disc 6.
• Disc 6 rotates in the plane of the drawing, about axis 7.
• Each disc 6 is provided with two clamping elements 5.
• Each clamping element 5 is capable of rotation about an axis 8 with respect to disc 6, between a position in which a supplement is engaged and a position in which said supplement is released.
• Figures 1 and 3 show the upper clamping element 5 in the engaging position, in which a supplement 10 is engaged, said supplement extending along the surface of a rotatable disc. While clamping element 5 passes opening 4, clamping 5 is pivoted about axis 8 from its releasing position into its engaging position, so that the edge of the lowermost supplement from the stack of supplements can be engaged.
• Disc 6 then rotates in the direction of arrow 11 and the supplement 10 being engaged is pulled from holder 1 and transferred to a passing quire 12, which is being moved in the direction of arrow 14 by means of a conveyor belt 13.
• Clamping elements 5 and rotatable disc 6 may be driven hydraulically or electrically, or by different means.
• a supplement 10 being engaged may be pressed against the shell surface by a guide (not shown) , or be drawn against said shell by air channels (not shown) .
• the supplements 2 present in holder 1 form a stack in which the supplements are positioned with respect to each other by means of the film of glue 3. Due to the presence of said film of glue the stack of supplements can be handled and placed in the holder without any difficulty, whereby the supplements 2 cannot move with respect to each other.
• the presence of the adhesive between the supplements makes it impossible to separate the lowermost supplement 2 of the stack from the next supplement by pulling the lowermost supplement from the holder.
• the surfaces of the two supplements 2 must be separated from each other by moving them apart in a direction substantially perpendicularly to said surfaces. Said moving apart may take place by blowing air between the supplements, as is shown in the embodiment of Figures 1 and 2.
• the end of a blow pipe 15 is thereby present near opening 4 in the holder, which blow pipe is capable of blowing air between the supplements in the direction of film of glue 3 , as is indicated by arrow 9 in Figure 2.
• Said blowing of air facilitates pulling the lowermost supplement from the holder without the film of glue 3 coming into contact with the next supplement 2 again in a disadvantageous manner.
• air is thereby supplied under a pressure of more than 2 atmosphere, and the blow pipe is provided with a wide nozzle.
• a plate-shaped separating element 16 is used instead of said blow pipe, which element is capable of movement in the direction indicated by arrow 17. Separating element 16 can be inserted between supplements 2 to the position shown in Figure 4.
• the separating of the supplements by means of a blow pipe on the one hand and by means of a plate-shaped separating element 16 on the other hand may also take place simultaneously by combining the two separating methods.
• the separating element may also function to support stack 2.
• Figures 5, 6 and 7 show another embodiment of the invention.
• Figure 5 is a bottom view of a separating element 16 which is rotatable about axis 20. Axis of rotation 20 extends substantially perpendicularly to the supplements 2 in the stack.
• Figure 5 shows the stack of supplements located directly behind the supplement 2 that is to be separated. The stack is viewed from below, as it were.
• Disc-shaped separating element 16 rotates right along supplement 2 in the direction indicated by arrow 21.
• the elongated suction nozzle 22 illustrated in a broken line
• a part 23 of supplement 2 is bent forwards relative to the plane of Figure 5, so that said part 23 will land on the front side of separating element 16.
• Suction nozzle 22 is provided on a sloping surface 24, which is illustrated in a broken line in Figure 7.
• Surface 24 extends obliquely relative to the plane in which separating element 16 rotates, so that part 23 of supplement 2 will bend over when suction nozzle 22 moves directly past supplement 2, whereby part 23 will slide over the sloping surface 24.
• Figure 7 furthermore shows suction pipe 28, which extends towards suction nozzle 22.
• Separating element 16 is furthermore provided with guide portion 25, which comprises a sloping guide surface 26. Further rotation of separating element 16 brings guide portion 25 near supplement 2, whereby sloping guiding surface 26 bends part 23 of supplement 2 further forwards relative to the plane of Figure 5. Part 23 of supplement 2 can then be readily engaged so as to be pulled away from the stack, whereby rebondable film of adhesive 3 lets go. Said engaging may take place by means of disc 6 as shown in Figures 1-4.
• FIGS. 6 and 7 are sectional view of fastening element 27, by means of which separating element 16 can be fastened to a rotating shaft.
• Suction pipe 28 is connected to a vacuum pump via said shaft (not shown) .
