Abstract
The present invention relates to a stack made up of a plurality of bags (1), in particular newspaper bags, that are blocked together and which, in order to ensure a manufacturing process that is simple and above all else can be conducted at a high cyclic rate, has in the area of an insertion opening (2) a suspension strip (13) that is welded on and is manufactured by separator welding tools (33, 34) that are preferably arranged in a twin configuration and are fed to a subsequent collector (35).
Description
Stack Comprising a Plurality of Elongated Bags of Plastic Film that are Joined to Each Other, in Particular Such Bags Intended for Newspapers, and a Method and Machinery for Manufacturing These The present invention relates, first, to a stack comprising a plurality of elongated bags that are of plastic film and joined to each other, in particular, such bags as are intended for newspapers, preferably with at least one additional pocket, with at least one suspension opening in the area of the insertion opening for the bag, and a suspension element that is joined to each bag in the stack so as to be removable therefrom.
Bags of the type discussed herein are used, in particular, to provide a large measure of protection against the weather for newspapers, magazines, or the like. Very often, these elongated bags incorporate an additional pocket in which a diskette or the like can be inserted.
As a rule, some 10 to 20 , at most 25, such bags are combined to form a stack and are held together by a cardboard handle strip. This handle strip, which serves as a suspension element can be secured at the edge of a tear-off tab by clasps.
For practical purposes, a stack up of this kind is carried by a newspaper boy who, when so required, and if this has not already been done, fills a bag with a newspaper or magazine in order that the filled bag can be torn off the stack and then placed in a position that is accessible to the recipient.
The use of three different materials, namely, cardboard for the handle strip, metal for the clasps, and plastic for the actual bag results in considerable recycling costs, since these materials have to be collected separately from each other. In addition, manufacturing bags of this kind is extremely difficult, so that in practice such bags can only be manufactured at a speed of some 40 to 60 cycles per minute.
It is the objective of the present invention to produce a stack comprising a plurality of elongated bags that are of plastic film, in particular such bags as are intended for newspapers, which are joined to each other, and which can be transported and handled easily. In addition, the present invention proposes a method for manufacturing bags of this kind that can be combined to form a stack, whereby a simple and cost-effective manufacturing process is made possible. Finally, machinery is to be created that to a large extent uses familiar assemblies and makes it possible to manufacture bags of the type discussed herein at a comparatively high cyclic rate.
From the standpoint of the product, the objective of the present invention has been achieved in that the suspension element is formed by a tear-off section of plastic film that protrudes at one end of the bag. This tear-off section can be formed, for example, from a separate tab that is welded to one wall of the bag in the area of the insertion opening, essentially parallel to a line of perforations. The insertion opening can be closed advantageously by a draw string or a rain flap.
A further advantageous feature of the present invention is that the pocket is attached to the end of the bag that is opposite the insertion openings, and that on its filler opening, which is essentially parallel to the insertion opening, this pocket has a flap that projects on one side.
If necessary, this can be made in one piece from the material used for the pocket and can be provide on its inner side with a strip of adhesive that can if necessary be covered by a protective strip.
From the standpoint of the machinery that is used, the present invention is distinguished mainly in that the device that is used to join the individual bags to each other in the stack is configured as a blocking machine and in that, in addition, a tab-strip supply device is also provided. The continuous feed of a tab strip makes it possible to achieve a comparatively high cyclic rate of, for example, 100 to 125.
This is further facilitated in that the device has two separator welding tools that are arranged transversely to the direction in which the web of plastic film is fed and which can be moved synchronously up and down, and in that, in addition, the collector that is arranged after the separator weld tools as viewed in the direction of feed of the plastic film incorporates the stack- pin belts of a stack-pin conveyor, in which the bags with the tab strips are taken from the stack belts, the bags being held by the pins on the conveyor belts as far as the stack belts and then discharged in the area of the stack-pin conveyor by a removal device, and are then blocked with each other in the area of the tab-strip.

Figures 6 to 10: additional, modified embodiments of the bag.
The bag 1 that is shown in Figure 1, which is of plastic film, has at its upper end an insertion opening 2 that extends as far as a lower bottom seam 3 of the bag and serves, for example, to hold a newspaper 4, a magazine, or the like. In the lower area of the bag 1 there is a pocket 5 that is similarly of plastic, for example transparent plastic, and is welded to one wall of the bag 1 by a welded seam 6. This pocket is used as an advertisement pocket and can be used, for example, to hold a diskette 7, as is shown in Figure 1. A flap 8 is provided to close the pocket 5, and this is arranged either in an extension of the bag 1, as is shown in Figure 1, or it can be formed from an offset extension of the bags material. In any case, the flap is provided with an adhesive strip 9 so that once the diskette has been inserted, the pocket can be closed off at the lower end. If the pocket is not used, the adhesives strip 9 can be covered by a protective strip (not shown herein).
At the upper end of the bag, i.e., in the area of the insertion opening 2, there is a line of perforations 11 in the rear wall of the bag. A suspension element in the form of a tab-strip 13 that is of plastic is welded essentially parallel to this line of perforations by way of a welded seam 12. The tab strip 13 incorporates a suspension opening 14 and, if necessary, stack-pin openings 15 and blocking points 16. A plurality of bags is combined to form a stack 17 using these blocking points 16, as is shown in Figure 3.
Figure 2 shows different suspension openings in the suspension element 13.
These are configured depending on the purpose of the bag and their utility. Above all, it is possible to select the shape of the suspension element and/or the thickness of the material that is used, as is required.
Figures 4a and Sa show a supply station 18 that is used to feed a first web 19, a second web 21 for manufacturing the bag, and a supply device 22 for a web (not shown in detail herein) for manufacturing the pocket 5. In order to produce the appropriate, necessary longitudinal welded seams, the webs are passed along a first longitudinal welding machine 23 and a second longitudinal welding machine 24. In addition, reference point 25 shows an additional feed station for the tab strips, which is not shown in detail in Figures 4a and Sa. A strip deflection system is shown at reference point 26. An adhesive-strip feed station 27 and an adhesive application station 28 are also provided. Beneath the adhesive-strip feed station there is a longitudinal perforating device 29, and a machine for punching the holes in the handle is shown at reference point 31.
The machinery shown in Figure 4b and Sb is used for the further production of the bag according to the present invention. Essential for the present invention is a transverse-cut welding device 32 that incorporates two welding tools 33, 34 that are arranged essentially transversely to the direction of movement of the webs and can be moved synchronously up and down; the spacing between these two welding tools is equal to twice the width of a bag section of the web of plastic film. Thus, two bags can be manufactured in each cycle of the machinery.
In practice , the bag or the pocket can be filled by machine, although this is not shown herein.
In order to achieve the comparatively high cyclic rate of at least 100 to 125, a collector 35 is arranged after the separating welding device 32; this is described in greater detail below.
First, the collector has a conveyor 36 that extends on one side into the area of a guide table 37 or of guide belts in the area of the transverse-cut welding device 32. The conveyor 36 has endless belts 38 that are routed about guide rollers. The belts can be provided with pins that can penetrate the edges of the bag when the bag is moved in the direction of feed. By this means, the bags can be moved into the area of a stacking pin conveyor 9 that lies partially beneath the transport device 3G. The bags on the stacking pins 41 of the stacking-pin conveyor can be moved off by a removal device (not shown in detail herein) and gathered into stacks. Before the bags that are stacked in packets are removed, they are blocked together by a blocking device (not shown herein).
Figure 6 and Figure 7 show the configuration of the bag as a so-called draw-string bag. Once it has been removed from the stack 17, a bag of this kind can be closed at the insertion opening 2 by a draw tape or string 42.
Another alternative is shown in Figure 8 to Figure 10. In this embodiment, the bag 1 can have the insertion opening 2 closed by a rain flap 43 that is secured by an adhesive strip 44.
Figure 2 shows different suspension openings in the suspension element 13.
These are configured depending on the purpose of the bag and their utility. Above all, it is possible to select the shape of the suspension element and/or the thickness of the material that is used, as is required.
Figures 4a and Sa show a supply station 18 that is used to feed a first web 19, a second web 21 for manufacturing the bag, and a supply device 22 for a web (not shown in detail herein) for manufacturing the pocket 5. In order to produce the appropriate, necessary longitudinal welded seams, the webs are passed along a first longitudinal welding machine 23 and a second longitudinal welding machine 24. In addition, reference point 25 shows an additional feed station for the tab strips, which is not shown in detail in Figures 4a and Sa. A strip deflection system is shown at reference point 26. An adhesive-strip feed station 27 and an adhesive application station 28 are also provided. Beneath the adhesive-strip feed station there is a longitudinal perforating device 29, and a machine for punching the holes in the handle is shown at reference point 31.
The machinery shown in Figure 4b and Sb is used for the further production of the bag according to the present invention. Essential for the present invention is a transverse-cut welding device 32 that incorporates two welding tools 33, 34 that are arranged essentially transversely to the direction of movement of the webs and can be moved synchronously up and down; the spacing between these two welding tools is equal to twice the width of a bag section of the web of plastic film. Thus, two bags can be manufactured in each cycle of the machinery.
In practice , the bag or the pocket can be filled by machine, although this is not shown herein.
In order to achieve the comparatively high cyclic rate of at least 100 to 125, a collector 35 is arranged after the separating welding device 32; this is described in greater detail below.
First, the collector has a conveyor 36 that extends on one side into the area of a guide table 37 or of guide belts in the area of the transverse-cut welding device 32. The conveyor 36 has endless belts 38 that are routed about guide rollers. The belts can be provided with pins that can penetrate the edges of the bag when the bag is moved in the direction of feed. By this means, the bags can be moved into the area of a stacking pin conveyor 9 that lies partially beneath the transport device 3G. The bags on the stacking pins 41 of the stacking-pin conveyor can be moved off by a removal device (not shown in detail herein) and gathered into stacks. Before the bags that are stacked in packets are removed, they are blocked together by a blocking device (not shown herein).
Figure 6 and Figure 7 show the configuration of the bag as a so-called draw-string bag. Once it has been removed from the stack 17, a bag of this kind can be closed at the insertion opening 2 by a draw tape or string 42.
Another alternative is shown in Figure 8 to Figure 10. In this embodiment, the bag 1 can have the insertion opening 2 closed by a rain flap 43 that is secured by an adhesive strip 44.
