Definitions

  • the invention relates to a transport device for transporting sacks or bags according to the preamble of claim 1, a method for transporting sacks or bags according to the preamble of claim 5 and a device for producing sacks or bags according to the preamble of claim 6.
  • Generic transport facilities are necessary in order to transport individual semi-finished sacks, for example individual tube pieces, to stations for bottom formation or also finished sacks, bags or the like (hereinafter referred to as sacks for short).
  • sacks for short.
  • several transport devices are often provided, for example in order to move the sacks in a subsequent transport device at an accelerated rate compared to the preceding transport device.
  • a transport element extending in the transport device, it may be necessary for parts of the transport devices, in particular a transport element extending in the transport device, to come into contact with the floor or a freshly produced floor or in particular to lie on it.
  • a transport element basically presses the sack against a counter-surface with a pressing force.
  • the object of the present invention is therefore to provide a transport device and a method with which the sacks can be transported safely and with which undesired sticking or blocking can be avoided.
  • the sack is transported safely according to the invention by placing the transport member on a floor.
  • the alternative approach that the transport element does not rest on the bottom but on the sack body, can lead to malfunctions, particularly in the case of incorrectly manufactured sacks, for example if a bottom cover sheet is missing and the side flaps stand up. Such a raised side flap can lead to the bag getting caught in the manufacturing device, which can often only be removed manually.
  • a transport device works more reliably than one without the measure mentioned.
  • a pressing force acting on the ground also has the advantage that the freshly glued, welded or hot-air sealed bags additionally be pressed to further strengthen the connection, so that the bag can ultimately be made more stable.
  • the pressing force is reduced in areas of the floor. Such areas are in particular edge areas of bonds, so that the adhesive is not squeezed out here.
  • the area of the base in which the pressing force described is reduced includes the transition from a number of layers to a larger or smaller number of layers. Because such edges of layers are usually the places where the greatest pressing force prevails and where the effects described above primarily occur here.
  • the width of the transport element (measured transversely to the transport direction) is preferably less than the width of the base in order to avoid strong compression of the folded edges of the base. Excessive compression can lead to damage to these folded edges, which could then burst open, for example, when a filled sack is filled or dropped.
  • the transition from a number of layers to a larger or smaller number of layers includes the open end of a filling valve. This measure helps to increase the quality of the entire sack production.
  • the bottom of the sack or bag is a cross bottom or a valve cross bottom sack.
  • the sack transported by the transport device is a cross-bottom sack and in particular a cross bottom valve sack. Since its construction and production is comparatively complex, there is a great risk of unintentional sticking or blocking if it is transported with conventional means of transport. The combination of the transport device according to the invention with cross bottoms is therefore particularly advantageous.
  • each transport element resting on a bottom of the sack or bag.
  • each sack or bag comprises a base at both of its ends, on which at least one transport element rests.
  • the transport device can be used to transport sacks or bags which comprise heat-sealable material.
  • a heat-sealable material is characterized by the fact that the surface of the material is slightly melted from the surface by the action of heat, without the material being converted into the molten form over the entire layer thickness, as is the case with welding, for example. Two parts of the bag that have melted in the area of the surfaces can then be placed on top of each other and pressed so that a firm connection is created when the material cools down.
  • a heat-sealable material is preferably a plastic, a plastic coating or a plastic fleece. In particular, if these plastics comprise or contain polyethylene (PE), the possibilities described above are given.
  • the transport device can be used to transport sacks or bags which comprise a fabric made from stretched polyolefin threads and a coating and, in particular, consist of this fabric and this coating.
  • sacks or bags which comprise a fabric made from stretched polyolefin threads and a coating and, in particular, consist of this fabric and this coating.
  • the fabric and especially the coating that has been heated by the hot air first cool down slowly. The invention thus effectively prevents the blocking of areas that should not be connected to one another.
  • the transport element has recesses, recesses, indentations or the like in the area in which the pressing force is reduced. With sufficient depth of these recesses, recesses, indentations or the like, the pressing force is even reduced to 0, which is also advantageous. Although it is also conceivable and in some cases advantageous to lift the transport element from the bottom of a sack with a lifting device in the described areas with reduced pressing force, recesses, recesses, indentations or the like are easier to implement and less susceptible to wear during operation of the transport device.
  • elevations are provided on the transport element in the vicinity of the areas where the pressing force is reduced. It goes without saying that these elevations must not be in those areas since the elevations provide an increased pressing force. Compared to this increased pressing force, the pressing force is reduced in the areas mentioned. Such ridges can be elongated. It is advisable for these to run transversely to the transport direction of the transport elements. In one embodiment, provision can be made to provide a large number of elevations and to provide a large distance between two adjacent elevations in the areas mentioned with reduced pressing force, which completely leaves out the area mentioned. It is also advantageous if these elevations are releasably attached to the transport element in order to be able to move these elevations or replace them with other elevations. In this way, the transport element according to the invention can be adapted to the floor geometry that is actually produced.
  • the elevations can comprise flexible material, which develops a spring-like force effect, for example.
  • the transport element comprises at least two recesses, recesses, indentations or the like, the distance between which corresponds to the distance between two sacks or bags transported with the transport device.
  • the "distance between two sacks” does not mean the empty space between two sacks, but rather the distance between two equal points or lines, such as the distance between the leading edges of two sacks, the distance being measured parallel to the direction of transport.
  • this comprises at least one circulating transport belt.
  • the invention can be implemented in a particularly simple manner with a transport belt, in particular if the transport belt comprises cutouts, recesses, indentations or the like. Such gaps, recesses, indentations or the like can easily be taken into account in the manufacturing process of the conveyor belt.
  • the recesses, recesses, indentations or the like can be introduced into the transport belt subsequently, for example by machining.
  • transport devices that are already present can in particular be used according to the invention by subsequently designing the transport belts in accordance with the alternative described above.
  • the counter-surface comprises at least one circulating transport belt. This is preferably to be moved at the same transport speed as the transport member described above, which is designed as a transport belt, so that the sacks can be transported reliably and safely.
  • the 1 shows a transfer station 100 with a first transport device 101, with which at least one sack 102 can be transported.
  • Transport device 101 is preferably used to transport bags to different processing stations within one in the figure 4 transport device shown for the production of sacks or bags.
  • the transport device preferably includes two pairs of transport belts 103 and 103', each of which includes an upper belt 104, 104' and a lower belt 105 and 105'.
  • a force acting in the direction of the respective other belt acts on the upper and lower belts of a pair of transport belts 103 and 103', so that it is ensured that the bag 102 does not move relative to the transport device.
  • the lower belt can be fitted with magnets and the upper belt can contain a magnetizable material, so that there is a magnetic attraction force between the two belts.
  • a further transport device 110 is provided, which is designed according to the invention already described above.
  • the sacks can be transported faster than in the first transport device 101, so that two consecutive sacks are at a sufficiently large distance from one another for stacking.
  • the transport device 110 comprises two pairs of transport belts 111 and 111', each comprising an upper belt 112 and 112' and a lower belt 113 and 113', with the respective lower belt 113, 113' serving as a counter-layer for the respective upper belt 112, 112', the Bag is transported between the upper belt and the associated lower belt.
  • One measure can be a coating of the transport belts 112, 112', 113, 113' that imparts adhesive force.
  • a further measure can be devices which apply a force to the individual conveyor belts, which is directed in the direction of the other belt. Such devices can be pinch rollers that are spring mounted and press on the backs of the belts.
  • the upper straps 112, 112' and the lower straps 113, 113' are shown with different widths in this view for the sake of clarity, but can have the same width in practical implementation.
  • the width of these belts preferably corresponds to the smallest bottom width that can be produced in the device for producing sacks or bags.
  • This smallest floor width is preferably greater than 60 mm, in particular greater than 75 mm.
  • the width of these belts is somewhat smaller than the smallest bottom width that can be produced in the device for producing sacks or bags.
  • up to 10 mm should then be deducted from the numerical values given above. This measure serves to avoid damage to the folded edges. In the case of sacks made of coated polyolefin fabric, such damage is also referred to as a broken edge.
  • the upper straps 112, 112' lie on the bottoms 120, 120' of the sack 102, while the lower straps 113, 113' are in contact with the rear wall of the sack body 121, which is not visible.
  • the bottoms 120, 120' are parallel to the plane that is spanned by the bag body 121.
  • the sack 102 is conveyed in the so-called transverse transport. This means that the longitudinal axis of the bag is aligned transversely to the transport direction z.
  • the figure 2 shows the already in the figure 1 shown transfer station 100 in side view, wherein the bag 102 is not shown.
  • the reference numbers of the conveyor belt pairs and the individual belts were from figure 1 accepted.
  • the upper belt 104' of the transport belt pair 103' which is preferably a steel belt, is guided over a deflection wheel 201, which rotates in the direction of rotation R1 and can be driven in the process.
  • the lower belt 105' is guided over the deflection wheel 202, which rotates in the direction of rotation R2. This deflection wheel 202 can also be driven.
  • top strap 104 and The lower belts 105 are provided with the same deflection wheels as the deflection wheels 201, 202, it being possible for the deflection wheels for the upper belts to be arranged on a common axis. The same applies to the deflection wheels for the lower belts.
  • the upper belt 112' of the transport belt pair 111' is guided over the deflection wheel 203, which rotates in the direction of rotation R3. Furthermore, the lower belt 112' of the transport belt pair 111' is guided over the deflection wheel 204, which rotates in the direction of rotation R4. As in the case of the transport belt pair 103', the deflection wheels of the transport belt pair 111' can be drivable. It goes without saying that the upper and lower belts of the transport belt pairs 103, 103', 111, 111' can be deflected via further deflection means such as further deflection wheels or rollers, since the upper and lower belts are preferably circulating.
  • the deflection wheel 203 is vertically spaced from the transport plane of the sacks, i. H. that the upper belt 112' is not yet in contact with the sacks after leaving the deflection wheel 203.
  • Contact can be established by providing a deflection roller 205 over which the top belt 112' can also be guided, so that the deflection roller 205 presses the top belt 112' onto the sack.
  • the lower belt 113' and the part of the upper belt 112' running between the deflection wheel 203 and the deflection roller 205 form an inlet funnel for a sack 102 in order to reliably grasp it without the sack buckling or warping.
  • the deflection roller 205 is arranged at a position in the transport direction z at which the lower belt 105 ′ of the transport belt pair does not yet come into contact with the deflection wheel 202 or just about. In this way, an overlapping of the transport devices 101 and 110 is ensured, so that the bag 102 is never guided without sufficient holding forces during the transfer. This also avoids buckling of parts of the sack or a change in the position of the sack 102 relative to the transport devices.
  • the figure 3 now shows the upper belt 112' and the lower belt 113' of the transport belt pair 111' in detail.
  • the transport belt pair 111 is preferably designed in the same way.
  • a sack 102 is additionally shown, which is moved forward in a clamping manner between the two belts 112' and 113'.
  • Numerous, equidistantly arranged teeth 301 can be seen on the sides of the belts facing away from the bag 102, which indicate that the belts can be designed as toothed belts in order to avoid a relative movement of the belts to the associated deflection wheels, which are accordingly designed as gear wheels be able.
  • the sack 102 can be equipped with a valve 122 which can be part of one of the two bases 120, 120'.
  • the valve is in this case a tubular piece which ensures access from the outside into the interior of the sack 102 in order to be able to fill it, but also to prevent the product from escaping later. It is therefore convenient for filling that access through the valve is not blocked, for example by the layers of the valve connecting to one another.
  • a recess 302 is made in the upper belt 112', with the result that the upper belt does not press the sack against the lower belt 113' in this area, or at least with reduced force.
  • the recess 302 can be produced, for example, by machining.
  • the depth of the recess can be at least 1 mm, but preferably at least 5 mm.
  • Belts that are used in pairs of conveyor belts are often reinforced with metal wires in order to reduce the longitudinal stretching capacity of the belt. In this case, the depth of the recess is only so great that the metal wires are still covered with at least 1 mm of material. This prevents corrosion of the metal wires.
  • the material of the belt referred to may comprise a rubber or a plastic such as polyurethane. These materials are easy to edit afterwards.
  • the position of the cutout is chosen so that it covers the front edge 123 of the valve 122 .
  • the pressing within the transport device 101 is critical, because if the layers of the valve are connected to one another at the front edge, a filling tube of a filling device cannot gain access to the interior of the sack 102.
  • a connection in the rear area of the valve is not very critical, since a filling tube that could be inserted into the valve in the front area can separate such a connection again. Therefore, the recess in the, seen in the transport direction z, cover the rear area of the valve, as is the case, for example, in FIG figure 3 can be seen.
  • the recess is at least 1 cm long, but preferably at least 5 cm long. Furthermore, it is provided that the recess is a maximum of 20 cm long, in particular a maximum of 15 cm, in order not to reduce the tensile strength of the belt excessively.
  • the width of the recess transverse to the direction of transport preferably corresponds to the width of the belt, ie no webs or the like remain in the side areas of the belt. In another embodiment, webs, preferably with a maximum width of 1 cm, can also be advantageous in order to at least partially maintain the strength of the belt compared to belts without recesses 302 .
  • the upper belt 112' now has elevations 310. Accordingly, the entire top belt 112' does not lie against the bottom, but only this elevation 310, which now presses the sack 102 or its bottom against the bottom belt 113'.
  • a linear or punctiform pressing force is now provided. It can be seen that the elevations 310 have a uniform, preferably constant distance from one another in the transport direction z. Only in the area 311, in which the pressing force is reduced, two adjacent elevations 310 have an increased distance. In other words, these two increases delimit the area 311.
  • the figure 5 shows a non-inventive modification in the figure 4 shown embodiment of the invention.
  • Elevations 320 can be seen here. These increases 320 can be configured lower than the increases 310 in the figure 4 . However, no further elevations are provided, so that in this exemplary embodiment the upper belt 112′ rests on the floor outside of the area in which the pressing force is reduced. Because of the flexibility of the belt, it is slightly deflected by the elevations 320, but this is not problematic for operational safety. The area in which the pressing force is reduced is also limited by the elevations 320 in this exemplary embodiment.
  • the increases 310, 320 in the embodiments of Figures 4 and 5 may be fixed to the top strap 112' or detachable. The latter serves to adapt the pressing force to the dimensions of the floor.
  • the elevations 310, 320 can be individual knobs arranged in a row. Alternatively, elongate ridges such as rods or rods may be provided.
  • the elongated elevations and/or the nubs arranged in a row advantageously extend transversely to the transport direction z on the surface of the upper belt 112'
  • the figure 6 now shows a device for the production of sacks or bags 401.
  • a material hose 402 is fed to the device 401 .
  • This is advantageously done by unwinding the tube of material forming a coil 403 in an unwinding device 404 .
  • the tube 402 can then experience the so-called opening in the opening station 405 .
  • the material tube 402 is guided around an inner tool, which separates the two layers from one another, so that the layers, if they are connected to one another during one of the manufacturing steps of the material tube 402 were glued, separate. Only with separate layers can it be ensured that the following production steps can be carried out properly.
  • the separate material layers of the hose are then placed on top of each other again.
  • the tube of material 402 is now fed to the cross-cutting device 406, which separates the tube of material 402 into individual tube pieces.
  • the original transport direction x in which the tube or the tube pieces were transported in the direction of their longitudinal axes, is changed to the new transport direction z, so that the tube pieces are no longer in the direction x of their tube longitudinal axis (hereinafter also Extension direction of the tube pieces called), but are transported transversely thereto, so that the ends of the tube pieces for the purpose of forming bases 120, 120 '(see figure 1 ) are accessible from the side.
  • the bottom opening station 408 both ends of each piece of tubing are opened and the so-called bottom rectangles are placed.
  • a valve 122 is placed and fastened on one of the two open ends.
  • the open bottoms are now closed in the bottom closing station 410, with two flaps being placed one on top of the other.
  • the tabs can additionally be permanently connected to each other, for example by welding.
  • the final step in the actual sack manufacturing process is the application of a base cover sheet to each base in the cover sheet station 411.
  • the cover sheets can also be welded on or sealed on by means of a hot air supply.
