Description

The invention relates to a thermoplastic bag Plastic film with inlaid gussets, floor sweat seams and a possibly equipped with hanging holes upper tab protruding from the bag opening and a method and equipment for its manufacture. Under Bags also become carrying bags, sacks, heavy Gutsäcke, Shirt-carrier bags made of plastic films understood the.

As long as there are plastic carrier bags on the market, search both department store and industry according to the "ideal" bags design that takes advantage of the paper bag with the pre parts of the plastic material combined, i.e. an advertising effect same, cheap, easy and quick to open and easy to use filling bag with its own stamina, if possible, with  high longitudinal and transverse tensile strength, with carrying handle or Carry handle hole and optimal carrying safety, with only simple, powerful production method with minimal Use of materials and personnel costs as well as minimal investment tion costs can be produced. None of the ones on the market Consumer tote bags currently in use can do all of these Satisfy conditions. The well-known grip hole carrying case with Sticky sheet reinforcement is not easy and cheap to manufacture len; you have to fight with 3 material components alone, namely for the bag body, film for the adhesive sheet reinforcement, adhesive material (with its known problems, not least also pollution). It doesn't offer anything Requirements for simple and quick filling, because the adhesive film sides to open apart have to be brought. The well-known shirt carrier bag is relatively easy and cheap to manufacture, but only in multi-lane production, with a longitudinal separation can not be dispensed with, offers due to the longitudinal Separating seams do not have sufficient tear resistance and therefore none sufficient safety and no requirements for simple and quick filling, so far only a small portion of the bag as an advertising medium by printing be used.

The grip hole tote bag with extrusion-thickened sinus Wear edge is under special conditions and therefore only relatively easy to manufacture with restrictions, but none if without problems and offers no prerequisites for a quick and easy filling.

In many packaging processes, they are attached to holding pins suspended bag to be filled or blocked bag in Loading direction opened and opened by compressed air hold to fill the goods, the bag then detaches from its holder or is torn off and then is closed. Usable for this packaging process Bags must have an upper flap on which they are hung or be blocked and the upper flap possibly via a per  foration is separable from the bag. The previously known Bags with a one-sided top flap are so-called Side seam bags, as for example in DE-GM 85 14 551 are described. They are made in such a way that a flat plastic film is folded over, one edge one layer of film over the edge of the other layer of film stands. This top section forms the later top plate of the Side seam pouch connected by cross welds is produced with separating cuts. It is also possible to equip such side seam bags with a bottom fold. However, bags with bottom pleats and side seams have only one limited filling volume. Aim for bulky pack good bags with high filling volume, these are bags with be folds.

DE-OS 34 08 722 is already a tear-off bag thermoplastic film with a protruding one Flap, in which hanging holes are preferably arranged, the is designed with gussets and a bottom weld seam, known. Here the gussets are just like that of Upper flap opposite bag wall completely in the Cut out the area of the upper flap. By manufacturing due to the process, these known tear-off bags also have Upper flap and gussets on one long edge of the bag a longitudinal weld, in addition to the bottom weld seam.

The invention has for its object a bag thermoplastic film with top flap and sides fold with a high filling volume and an economical manufacture creating procedures for this.

To solve this problem is a gusseted bag made of thermoplastic film with a top flap and bottom weld according to the invention proposed that the Upper flap by extending the back of the bag  and the one on either side of the back Leg of the gussets formed opposite the front is. According to the invention, a bag with a high filling volume due to the side gussets and an enlarged filling opening and a simplified filling through the one-sided protruding upper flap and the access channel formed thereby te suggested.

The pouch according to the invention is further characterized thereby records that the top flap is covered by a full width the front of the bag as well as the one on either side Front leg of the side folds up to inner folded edge-reaching cutout is formed. In a further embodiment according to the invention, it is proposed conditions that the upper flap in the area of the bag opening Tear perforation has. At this tear-off perforation the Bags are separated from the top flap. The bags lie e.g. B. before in the chain assembly, the separation takes place at the same time from the bag chain. The tear-off perforation can be longitudinal or across, e.g. B. as a tear line parallel to the bag opening or in Shape of tear-off slots above the suspension holes be educated.

However, it is also possible to place the pouch in the area of the upper flaps to pack and block with at least one opening hanging hole. Here, in a further embodiment the invention the blocking as across the entire width of the Bag blocking welding carried out parallel to the tear line be formed seam or the blocking z. B. in the field of two outer corners of the top plate as a point, for example be trained weld and for the separation of ver blocked outer corners provided a corresponding perforation be. Depending on the purpose, the bags can also be used punched handle recess and / or on the front and Back in longitudinal extension of the bag one by extrusion thickened film center zone to increase the load capacity point. The bags can be blocked or on holding pins (Wicket bag) loose or in the chain assembly of the packaging are fed. An advantageous Ausge staltung provides that the bags in the chain together hang, with the back as well as the to the back too  legs of the gussets in both sides Go through the longitudinal extension and the top plate in the Bottom weld seam of the preceding bag adjacent Be richly provided with perforations forming a tear line is. To increase the load capacity and the filling volume can also enclose the bags with the gussets Diagonal welds for block bottom formation, starting of the bottom weld seam and, if necessary, additional diagonal Welds starting from the bag opening area point.

The invention can also be applied to shirt carrier bags, in which then according to the invention by means of a perforation tearable top flap on one of the two layers of film in the Neck area of the shirt protrudes and in the area of the upper flap to pack is blocked. Here too, the Erfin makes it possible a simplified filling by the enlarged not 2nd position of the filling opening stuck in the block and that resulting from the one-sided top plate Grip edge on the other side of the bag.

The bag 1 shown in FIG. 1 has side folds 5, a bottom weld seam 4 and the one side over the front side 1 a projecting upper tab 7. The stacked bags 1 are blocked by the Ver parallel to the bag opening Verblockschweißnaht 3 and have the punched hanging holes 2 in the area of the top plate in particular in the area of the blocking. The front 1 a of the bag ends at the bag opening with the cut or grip edge 71 , which extends over the entire width of the front 1 a and the adjacent legs 5 b of the side gussets 5 , as can be seen from the development of FIG. 3 . The upper tab 7 is formed by cutting out the strip 17 from the front and the adjacent legs of the gussets. The top edge 72 of the bag is formed by the top flap. The on the back 1 b of the bag lying leg 5 a of the gussets are not cut or cut. By blowing in compressed air from above or gripping the grip edge 71 , the bag 1 can be opened and filled easily and, after filling, torn off at the perforation line 6 running in the area of the bag opening between this and the blocking seam.

Instead of blocking, the bags with side gusset, bottom seam and top flap can also be held on wicket stacking brackets, for which the bags 1 shown in FIGS . 4 and 5 are particularly suitable. For this purpose, the top plate 7 has the hanging holes 2 , which are above tear-off slots or perforations 9 are assigned above for easier tearing from the brackets. The bag 1 can easily be opened to the front by grasping the grip edge 71 and, after filling, can be accepted by pulling off the holes 2 and perforation 9 .

Instead of the continuous blocking of the bags according to FIG . B. it is also possible, as shown in Fig. 11, in the area of the upper flap only in the corner areas to be welded to each other point by point, see the spot welds 85 , and then tear off the pouches 86 from the corner areas with the spot weld ß record 85 , deduct from the bracket, which is guided through the suspension holes 2 , and at the same time separate from the packing block. Tear-off slots 9 are also provided here above half of the hanging holes 2 .

The design of the bag according to the invention as a side gusset carrying bag to be packed is shown in FIG. 6. The bag 1 with side gussets 5 is designed as a carrying bag with the recess 8 in the handle and over the interlocking weld seam 3 , which extends over the entire width of the bag, on the upper flap 7 blocked to pack and has in this area the hanging holes 2 , which are punched. The Abreißper foration can also be continuous. Furthermore, to increase the carrying weight, the carrying bag can be formed with an extrusion-thickened central zone. The tear line 6, 6 a can also be perforated in the central region 6 and cut on the sides 6 a .

A further advantageous product design in the chain assembly is shown by the examples in FIGS. 7 and 10. According to FIG. 7, the bags 1 are side-gusset carrier bags with an upper flap 7 , with an extrusion-thickened extension of the film center zone 11 , with side gussets 5 , with bottom seam 4 , with tear-off perforation 6 in the area of the upper link 7 and carrying handle recess 8 in the chain assembly formed to be attached to one another. In addition, the bags can be designed with diagonal weld seams 10 for block bottom formation in the bottom region, ie starting from the bottom weld seam 4 . The bags 1 can also be formed as sacks with and without an extrusion-thickened central zone, with and without diagonal weld seams for block bottom formation below and above, as shown for example in FIG. 10, in a chain connection with tear-off perforation 6 .

In a modified form, the invention can also be applied to the configuration of shirt carrier bags, as shown in FIGS . 8 and 9. Here, in the area of the shirt cutout 12, the upper flap in the form of an opening lip is extended on one side at the back of the shirt-carrying bag 1 . This upper flap 7 is likewise provided with the perforation 6 along the cut-out edge, ie parallel to the cut-out edge 71 of the shirt. In the area of the upper flap 7 , the camisole carrying bags are then blocked together by welding 3 . The shirt pocket can also be easily gripped and opened at the front on the cut-out edge 71 and, after filling, can be separated by tearing from the blockage holding the packs in the rear wall. The shirt pocket designed according to the invention can also be safely opened on one side at the front, while the back is still held by the blocking and is only torn off at the perforation during or after filling. The blocked shirt carrier bags are z. B. held on one or two hanging holes 2 .

The structure and operation of the device for cutting out the strip from the film tube and producing the upper flap of the bag is explained with reference to the basic Dar positions of FIGS. 12 to 17. According to FIG. 12, the film tube 100 is transported in the direction of arrow A with the side folds 5 inserted. For a rational production, it is also possible to process several film tubes side by side in one machine, accordingly, a corresponding number of cutting devices must then be provided across the width of the machine. The cutting device 15 is designed as a twin tool with the cutting tool parts 15 a , 15 b , which each fold from both sides engage in the sides, the distance between the guide plates 13 a , 13 b from each other being only slightly larger than the width of the strip to be cut. For clamping the upper and lower gusset parts on both sides of the cutting tool, the hold-down device 14 a, 14 b, 14 c and 14 d on both sides of top and bottom sides of the tubular web 100 with the guide plates cooperatively arranged. For the cut-out strip 17 , a suction device 16 is arranged above the tubular film approximately in the middle and above the strip.

The opening plates 80 , see Fig. 12 and Fig. 16, are in a rigid position, as close as possible to the guide plates in the transport direction of the tube sheet in front of the same in the th according to the side fold depth and bag length adjusted, ie adjustable position. The opening plate must have such a thickness that it opens the side folds so far that the guide plates inserted periodically from the outside, ie from the sides, can be moved smoothly into the side folds. After each cutting process, the guide plates are moved out of the side folds, whereby both a rotational movement and a linear movement are possible.

The area of the cutting device is also assigned a welding device, for example in the form of a welding bar 181 , which is used for pressing and welding the cut edge assigned to the bag bottom in the transport direction of the tube web after the strip 17 has been cut out onto the lower film web.

For the entire device of cutting out the strip with guide plates, suction device and welding device, a pneumatic or mechanical actuation unit is provided, which is synchronized with the working rhythm of the subsequent welding device for the bottom seam and works cyclically with it. The distance between the two guide plates assigned to each other in pairs forms the starting point for the twin cutting tool 15 a , 15 b .

The pre-welding device 181 and twin cutting tool 15 are set according to the length of the respective product at a distance from the welding device for the bottom seam. The pre-welding device 181 is used to press the upper (open) film web of the cutting edge subsequently assigned to the bottom weld seam onto the lower film web either immediately before or during or immediately after the cutting process of the twin cutting tool and thereby easily weld it on. This ensures that no air can penetrate into the film tube during further transport of the tubular web and a trouble-free pass through preferred rollers and welding device is guaranteed. If it is not necessary to weld the upper to the lower film web depending on the holding of the web during further transport or depending on the use of the packaging product (e.g. for filling from below, i.e. the tube opening achieved by the twin tool), this may not be desirable The welding device is switched off and put out of operation.

The twin cutting tool 15 is now set to the cutting length, approximately half the width of the tubular web. During the dwell state of the film web, that is, the action time of the bottom seam welding device, the twin cutting tool 15 is actuated and folded 5 into the sides held in the open position. Here, the side gusset layers 5 a , 5 b are clamped from below and above against the guide plate by means of the hold-down devices 14 a to d . The twin cutting tools 15 a , 15 b then pierce from both sides with the flat front tip, see Fig. 15, the side gusset inner edge and simultaneously cut through the upper film web on both sides of the outer tool longitudinal edges. In the event that only one slot is desired, the cut is only made on one side of the outer longitudinal edge of the tool. The two cutting tools coming towards each other towards the film tube web center are controlled in such a way that the cutting tool 15 a shortly before the cutting tool 15 b reaches the web center, ie the cutting end of the tool or cuts a few millimeters beyond the web center; Cutting tool 15 b works in principle the same as cutting tool 15 a , but only reaches the center of the path after cutting tool 15 a is already on the way back. This results in a slight overlap of the cutting center and thus a complete cutting out of the strip. Immediately after the cutting process has been completed, both cutting tools 15 a , 15 b lift off slightly and transfer the cleanly cut out strip 17 to the assigned strip suction device 16 when moving back. Immediately after the welding head of the welding device and the twin cutting tool unit have been lifted off the upper film web, the tubular web 100 is released for further transport. The z. B. rotating in the transport direction of the tubular part of the side gusset guide plates by a rotational movement or the like from the action area, ie led out of the gussets, so that the upper and lower layers of the gussets joined together by the weld 18 clear the way for further transport. The guide plates 13 a , 13 b arranged on the same axis on the opposite head adjust themselves to the action position.

This method of operation ensures that the strip 17 is always cut cleanly and taken away without major tool wear, the working speed can be absolutely adapted to the overall system performance, that is to say there is no reduction in performance, multi-lane on the same level in succession without a large gap between the individual Foil sheets can be worked. As a rule, the action space required for the gusset opening and guide plates as well as the twin cutting tool set, which goes beyond the product width, corresponds approximately to the width of the gusset assigned in each case.

The cutting tool can be executed depending on the expediency be as a double butt cutting knife, cold or heated; Double Scissors cut knife, cold or heated; Double rotation cutting knife or saw, punching tool, from above punches.

The design of the puncture blade on the front edge of the Cutting tool for opening the inside gusset edges remains the same regardless.

The handle required for the production of carrier bags  Hole punching can be a product length for single punching before the cut-out position for the strip. To precise control of bag lengths and positioning a photocell probe on one to the cutting device for the strip closest to the position.

The subsequent execution of the bottom seam welding device is known in principle and is depending on the bag design and Stacking system with a cutting or tear-off perforation knife as well as in the case of bag blocking with point or tape Equip the blocking tool.

The storage systems are of various types of bags gene adapt, the bags to pack in a known manner can be blocked, stacked on wicket hangers or loosely or wrapped in coils in rolls or in boxes can be folded.

The cutting out of a strip to produce a one-sided upper flap that can be torn off and blocked, is also used in a somewhat modified form in the manufacture of shirt carrier bags with blocking and tearing perforation. Here, in FIGS. 19 and 20 shown schematically, the cutting tool 15 on one side only, that is pushed from one side by the side fold 5 and guided to the middle of hose to the point where later in the stacked camisole tote bags, the blocking and Tear-off perforation should take place on the protruding upper flap. The cutting tool is in particular inserted obliquely to the front in the film running direction from the side, and the punching or cutting out of the film strip 17 can take place in the form of a circular tab 17 a . The cutting tool has a front sharp edge for pushing through the gusseted edge and also serves in flat form as a counter pressure bar for a punching device 82 acting on the upper or lower layer of film, the z. B. punches a round hole in the upper film layer, and which is additionally provided with a suction device for the punched-out film piece. However, it is also possible to cut only one slit in the upper film web, which is imaginatively positioned above the tear-off perforation of the shirt-carrying bag.

After cutting out the piece of film 17 a , the bottom is welded and the bags are separated and collected to packs ge. In the complete packs the shirt cutouts are then punched out and at the same time the remaining upper flap is perforated and blocked as a counterpart of the film cutout 17 a , so that the shirt carrying bags can later be torn off individually at the perforation.

In the Fig. 18 is shown schematically the principal formation and manufacture of gusseted bags with top flap, possibly with extrusionsverdickter longitudinal support zone in the chain composite at each hanging shown with tear-off and Tragegriffausnehmung, optionally with diagonal welds for block bottom out of a film tube. The film tube can be made of polyolefins, for. B. LDPE / LLDPE can be produced by extrusion with subsequent inflation to the film tube, wherein, if desired, a longitudinal extrusion thickening to about twice the film thickness over a desired width in the central region of the later bag is also produced. The film tube 100 is then fed to further processing via a buffer zone. As a rule, these are a print pre-treatment station I, which is equipped with an interval control system for interrupting the pre-treatment transverse to the film running direction in the later area of the bottom seam, in order to thereby also enable printing on the film in the side folds. The position setting he follows in adaptation to the positioning of the print image via a film web adjustment device, so that the print pre-treatment system I can be installed stationary. The individual printing units of the subsequent in-line printing press of the following printing station II are designed so that they can be switched off and on individually, that is, without interrupting the film run and the other printing units, in order, for. B. complete cliché, cliché rollers or color changes and readjustments during production. Then he follows the entry of the film tube 100 in the gusset insertion device III. This is followed by a web center control, and in the case of discontinuous work, for example for the manufacture of bags in chains, the punching device IV is connected to punch out the handle recess 8 . If the formation of a block floor is desired, a diagonal seam welding station V can be provided as the next station and action can be taken if necessary. In front of the bottom seam welding station VII, the cutting device VI with a guide for cutting out the strip and producing the upper flap of the bag is mounted directly. The cutting station VI includes the devices explained with reference to FIGS. 12 and 17. Between the cutting station VI and the bottom seam welding station VII or optionally in front of the cutting device, a photocell probe is arranged for controlling the repeat. A perforation device, for example a perforation knife for producing the tear-off perforation, is provided directly on the welding bar for transverse welding of the film tube for the bottom seam. The distance of the welding bar web for the bottom seam to the perforation knife is to be dimensioned such that, with the proper setting and function of the cutting device for the strip for the manufacture of the top flap and the photocell control, an exact positioning of the bottom welding seam in the pocket bottom area and the tear-off perforation in the area of the top flap immediately below it ensures is. An additional control system can then be provided which detects incorrect positioning and in this case switches off the further processing system. The fully welded bags and sacks, which are pre-perforated for later tearing, are then pushed out of the welding station VII in a chain-like manner in the direction of the arrow and then fall, for example, over an inclined slide into an intermediate storage trough and can be further processed and packaged from here.

With the system according to FIG. 18, carrier bags or sacks with or without diagonal weld seams in the chain assembly with tear-off perforation and top link, which results in a grip edge and thus the simple possibility of filling the bag or sack or carrier bag, can be produced continuously.

It is also possible to make the pouches according to the invention To produce flat film, from which by turning one half hose will.
