Definitions

  • the invention relates to a sack or bag production device according to the preamble of claim 1 and a method for sack or bag production according to the preamble of claim 15.
  • sacks or bags For the production of sacks or bags, these are processed with at least one processing station for carrying out a work step in the production of sacks or bags. This is about the production of at least one closed base on a material hose or a material sheet, the latter being first formed into a hose piece. To produce the floor, various individual steps are necessary, which can be carried out or are carried out in the respective work stations. Also unfinished sacks or bags are understood in the context of the invention by the term "sacks or bags”. This also includes the material hoses or material sheets as starting elements of the sack or bag production. Different sacks are produced by creating a closed sack on two bottoms, which can later be filled via a valve. An example of such a sack is a cross-bottom valve sack. Such cross-bottom valve bags are often used to transport building materials such as cement, fertilizers or other pourable or free-flowing products.
  • a transport system for supplying and removing sacks or bags to and from the processing station, the transport system comprising at least one transport belt with which the sack or bag can be transported by means of frictional engagement.
  • the sack or bag is held immovable relative to the transport belt.
  • cross-bottom valve bags are often transported orthogonally to their main axis of extension and often lying down, that is, horizontally. Often two parallel transport belts are used, each of which is in contact with one end of the sack near one end of the sack.
  • the object of the present invention is therefore to propose a sack or bag production device and a method for sack or bag production which avoids or even overcomes the disadvantages of the prior art.
  • the transport system comprises at least one transport belt with which the sack or the bag can be transported by means of frictional engagement, the transport belt is designed as a flat belt which has notches on at least one of its surfaces.
  • the surface acts on the sacks or bags via frictional engagement - also referred to as a transport surface - or a deflection roller or drive pulley acts on the surface for the purpose of guiding or driving (guided surface or drive surface).
  • a flat belt is characterized in that said surfaces have a width which is at least three times greater than the thickness of the flat belt. The side faces are therefore not to be understood as surfaces. The notches now have the effect that the flexibility of the flat belt is increased, so that this flat belt can also be guided around rollers or rollers with small diameters without causing damage to the flat belt.
  • a flat belt is in particular exclusively frictionally engaged by means of a Drive pulley driven. It is therefore irrelevant whether the drive pulley is in contact with the surface with notches or with the opposite surface.
  • the advantage here is that if a surface of the conveyor belt is worn, it can be rotated about its longitudinal axis so that the opposite surface can now take over the functions of the original surface. This means that the conveyor belt has a longer service life, so that ultimately costs can be saved.
  • the transport system is designed as a double belt conveyor, the sacks or bags being able to be conveyed in a clamping manner with the surfaces of the transport belts facing one another.
  • the frictional engagement between a sack or bag and the transport belt is further increased, which increases the transport reliability.
  • both conveyor belts are provided with notches on their surfaces.
  • the frictional engagement can be further increased if force supply means are provided which apply a force to the aforementioned transport belts which is directed towards the other transport belt in each case. This can be done in a simple manner by spring-mounted rollers, the spring force pressing the roller onto the transport belt.
  • the transport belt comprises at least one inner fiber made of a metal, in particular a steel wire. consists.
  • An inner fiber made of metal has the great advantage that it is flexible, but at the same time has high tensile strength, so that it elongates only insignificantly over the course of the operating time. Thus, even after a long operating time of a sack or bag manufacturing device according to the invention, a high quality of the sacks or bags is still guaranteed.
  • the transport belt comprises at least one inner fiber which is surrounded by a plastic, in particular a polyurethane.
  • a plastic sheathing of the inner fiber can be designed with a suitable choice of the plastic used in the desired hardness.
  • the flexibility of the conveyor belt can also be adjusted with a desired hardness so that it can be guided around the drive pulleys provided without damage.
  • Polyurethane is a plastic whose properties can be varied greatly, in particular by adding additives, so that the transport belt, in addition to its strength, also has a good frictional connection with the material from which the sacks and bags are made, in particular paper.
  • a transport belt that can be used in a sack or bag manufacturing device according to the invention preferably has a width between 10 and 50 mm.
  • Its thickness is preferably greater than 3 mm and less than 10 mm. Its coefficient of static friction is preferably between 0.3 and 1, in particular between 0.4 and 0.9. Furthermore, a plastic sheathing, which in particular comprises polyurethane, can be adapted in terms of its abrasion resistance, so that the conveyor belt has a long service life (the time it takes for a worn conveyor belt to be replaced).
  • the transport belt is designed as an endless belt, with at least one inner fiber being provided, which is endless, with the inner fiber being encased with plastic.
  • the inner fiber can be formed from at least one metal wire by joining its ends to form a continuous fiber. Subsequently, this continuous fiber can be provided with a plastic sheath, thereby creating an endless transport belt.
  • An advantage of this configuration of the transport belt is the elimination of a seam or a similar connection point, as is the case with a transport belt Prior art is known. Such a connection point often has particularly large tolerances, so that it is precisely at this point that quality losses can occur.
  • the transport belt is designed as an endless belt, the circumferential length being at least 30 meters.
  • Such a transport belt is particularly in combination with a device for the production of cross-bottom valve bags, which has a considerable length because of the numerous processing stations required.
  • the notches extend as far as the inner fiber.
  • the conveyor belt can be bent particularly well, so that smaller drive pulleys can be provided.
  • the notches themselves can have a triangular or rectangular cross-section, as will be clarified further below in connection with the drawing.
  • the flat belt also has notches on its second surface opposite the first surface. This is accompanied by an even better flexibility of the transport belt. In this case, a surface provided with notches is also in contact with the sacks or bags without any damage being visible.
  • the flat belt also has notches on its second surface lying opposite the first surface, the notches being arranged exactly opposite one another. This measure can again increase the flexibility.
  • the flat belt also has notches on its second surface opposite the first surface, the notches on the second surface being arranged offset in the longitudinal direction relative to the first surface. This variant improves flexibility, and the transport belt also has good stability.
  • the flat belt comprises a groove running in the conveying direction or a web running in the conveying direction on at least one surface.
  • At least one deflection pulley and / or one drive pulley and / or at least one further guide element preferably have a complementary profile, so that it is achieved that the transport belt has a very good straight-line ability.
  • the plastic material has a hardness of at least 50 Shore A. What is achieved here is that the transport belt is not deformed too much, which could affect the quality of the bags or sacks.
  • the plastic material prefferably includes white color pigments. This achieves a light coloring of the transport belt, which means that abrasion of the transport belt which remains on a bag or sack does not lead to strongly visible soiling of the sack or bag. Pollution is also often viewed as a quality defect.
  • a signal element can be an element that can be detected by a sensor, for example a magnetic element or any other element which, for example, reacts to radiation from the outside with a reflection of the signal.
  • the purpose is to determine the passage of the signal element in order to be able to determine, for example, a changing rotational speed. If there is a deviation from a setpoint speed, the actual speed can be adjusted, for example.
  • the above-mentioned object is additionally achieved by a method for sack or pouch production with at least one work step in a processing station, with sacks or bags being fed to and removed from the processing station with a transport system, the transport system comprising at least one transport belt with which the sack or bag is transported by means of frictional engagement.
  • the method according to the invention is characterized in that a flat belt is used as the transport belt, which has notches on at least one of its surfaces.
  • the Figure 1 shows as an example of bag or sack production a sequence of process steps for forming a base onto a piece of tubing within a sack or bag production device 100.
  • Each process step is carried out in an assigned processing station, which are labeled 1. to 7..
  • the hose pieces 8, which are already referred to as sacks or bags in the context of the present application, are preferably conveyed to the individual work stations by a double belt conveyor 9, the hose axis running transversely to the conveying direction but in the conveying plane.
  • the hose end is pulled open so that the now open bottom 10 lies in a plane which runs essentially orthogonally to the hose axis.
  • a valve label 11 is optionally applied to the open floor 10.
  • Another valve label 12 can be applied in the work station 3.
  • areas of the floor 10 are coated with glue in a manner not shown in detail.
  • the floors are then laid in work station 5, with areas of the floors sticking to one another due to the applied glue and thus forming a permanent floor.
  • a bottom cover sheet 13 can finally be glued to the laid-up bottom.
  • an imprint is optionally printed on the base cover sheet by means of a format cylinder 14.
  • the format cylinder 14 can carry raised clichés (not shown).
  • the double belt conveyor 9 comprises two revolving, endless transport belts 15 which are guided over deflection rollers 16. To transport the hose pieces, the two conveyor belts 15 are placed one on top of the other in areas of the double belt conveyor and are pressed together by rollers 17 acted on by spring forces, so that a displacement of the hose pieces relative to the conveyor belts is avoided.
  • the drive of the The transport belt 15 is shown as an example for the lower transport belt 15.
  • the drive comprises a drive motor, not shown, which drives the drive pulley 18.
  • the transport belt 15 is guided over the pulleys 19, which are arranged in such a way that the transport belt 15 wraps around the drive pulley 18 preferably over an angle of at least 180 °.
  • FIG. 3 now shows a detailed view of a transport belt 15 as it is part of a sack or bag manufacturing device 100 according to the invention.
  • This conveyor belt comprises at least one inner fiber 20, which can also be referred to as a neutral fiber, since it is neither elongated nor compressible.
  • a lower part 21 of a plastic sheath is arranged below the inner fiber.
  • an upper part 22 of a plastic sheath can be seen above the inner fiber.
  • the upper part 22 additionally includes notches 24, which preferably extend as far as the inner fiber. As shown, these notches can have a rectangular cross-section. This has the consequence that the remaining webs 23 assume a cuboid shape.
  • the lower part 21 can be provided with notches.
  • the Figure 4 shows a variant of the embodiment of FIG Figure 3 , in which the notches 24 are triangular or trapezoidal, so that the remaining webs 23 have a trapezoidal shape.
  • the Figure 5 shows an embodiment of a conveyor belt 15 in which both the upper 22 and the lower part 21 have notches 24, the notches in the upper part 22 and the notches 24 in the lower part being opposite one another.
  • the width of the notches can differ from one another in the upper and lower part.
  • FIG. 6 is a variant of a conveyor belt 15 according to FIG Figure 5 to see.
  • the notches in the upper part 22 and in the lower part 21 are offset from one another.
  • the width of the notches and the ridges can be so be chosen so that the webs in the upper part and the webs in the lower part overlap.
  • FIG. 3 shows a cross section of a conveyor belt 15. More than one inner fiber 20 can be provided.
  • the upper part 22 has a web 25.
  • a guide element 26, for example a roller, a disk or a guide rail, comprises a complementary groove 27 in which the web slides.
  • the guide element can also have a web and the transport belt can accordingly have a groove. It is also conceivable that the web or the groove of the conveyor belt is assigned to the lower part 21.
