Definitions

  • the invention relates to an apparatus and a method for producing bags made of coated plastic fabric.
  • Such bags have been known for some time.
  • the starting material for these bags is usually a tubular fabric, which is produced in round looms from stretched plastic tapes.
  • the stretched plastic tapes which often contain polypropylene, have a very high tensile strength in the longitudinal direction.
  • the low tensile strength of the plastic tapes in their transverse direction does not matter because in a tissue many tapes in the longitudinal and transverse directions of the subsequent bag run, so well absorb the forces in all directions.
  • the fabric may also be a flat fabric, which will later be added to form a tube to form a longitudinal seam.
  • the fabric is often coated with another plastic material in order to be able to connect different parts of the hose or of the later hose pieces to one another by means of a joining method without affecting the stretched plastic tapes.
  • a joining method is hot air sealing, in which the surfaces to be joined are fused and then brought into contact, so that the surfaces form a firm connection after cooling.
  • only the coating is heated, as the strength of the plastic tapes deteriorates when exposed to heat. In reality, one can However, some heating of the plastic tapes usually can not be avoided.
  • such compounds may also be prepared by adding an adhesive or liquified plastic. In particular, it makes sense to introduce between the surfaces to be bonded the same plastic, but in heated and liquefied form, with which the surfaces are already coated.
  • the trays are closed, whereby components of the trays are permanently connected to one another in the manner described above. It is possible to incorporate a valve in the ground to allow the subsequent filling of the bag.
  • the EP 0 571 728 A2 shows an apparatus for the production of paper sacks, wherein the quality of the glued bag bottoms by means of a CCD camera, which receives at least two images per bag bottom, is checked. To remove a faulty bag beats the EP 0 571 728 A2 a Ausscheideweiche before, the transport rollers and conveyor belts comprises.
  • the object of the present invention is therefore to propose an apparatus and a method with which the sorting out of defective bags can be done faster and more reliably.
  • At least one movable deflecting means (11) is provided, with which certain bags from the sequence of sacks ausschleusbar that the deflection (11) in the transport direction (x) at a distance (D) of at least three times the width (S B ) of a fabricated bag from the nip (2, 3), in that the sacks (4) between the nip and the deflecting means (11) can be conveyed by at least one double belt conveyor (7) which comprises at least two circulating transport means (5, 6), such as belts, and in that the deflecting means comprises a plunger (13) which can be introduced into the conveying path (x) of the bag and with which the bag can be deflected from the original transport direction.
  • the "certain sacks" may be the sacks identified as defective.
  • an essential aspect of the invention is now to arrange the deflection means at a sufficient distance from the last nip, so that the bags can cool sufficiently before they pass through the deflection.
  • the heat applied by the hot air which is introduced into the bag material for bottom closure and for application of the ground cover sheet, makes the material very soft and flexible. This laxity of the material is retained for a certain time after production.
  • the deflection means at least as far away from the last nip that the sack has completely left this nip before it hits the deflection means with its leading edge.
  • the material of which it is composed has cooled sufficiently and thus solidifies again, so that its deflection from the direction of transport in another direction can reliably take place.
  • the distance between the nip and the deflection can also be greater than a bag width to allow further cooling.
  • lobed bag material is also provided to promote the bags between the nip and deflection with at least one double belt conveyor, wherein a bag is then clamped between the two Lasttrumen of the upper and lower conveyor.
  • the strands are part of circulating conveyors such as belts.
  • other funding are conceivable, such as special holding means which are attached to rotating chains.
  • the bags are conveyed over a flat surface, for example via a table.
  • the bags get a full-scale support.
  • the surface of the table is advantageously arranged horizontally.
  • the upper run of the circulating transport of the upper part of the double belt conveyor at a high distance to the lower run should be at least 40cm, especially at least 60 cm.
  • aggregates that promote the cooling process of the bags, such as fans, can be arranged.
  • bags of various lengths can be produced in devices for producing bags of coated plastic fabric, it is particularly advantageous to provide two parallel double-belt conveyors, at least one of which is displaceable transversely to the transport direction of the bags. In this way, the strands of the conveyor can seize the bags near the bottoms, where during the manufacturing process a particularly high heat input occurs and the bags are particularly limp.
  • the newly added compared to the devices of the prior art cooling path and deflection means that a device according to the invention builds longer.
  • it is provided to supply the defect-free sacks to a further transport device, which then removes the sacks in a direction which runs in the direction of the longitudinal axes of the sacks.
  • cooling elements can also be provided between the nip and the deflecting element when the upper strand and the lower strand are not widely spaced.
  • the cooling elements may have various configurations, such as lines through which a liquid or gaseous coolant flows, which then preferably consist of metal.
  • Particularly advantageous is the arrangement of aggregates, which act on the bags from above with cooling air. This cooling air can then absorb and dissipate heat from the bags.
  • an error detection element is arranged between the nip and the deflecting element. This can be coupled to the deflecting element, so that in the case of a bag recognized as being defective, the deflecting element ejects this bag out of the sequence of the bags.
  • the error detection element may include an optical sensor that records images from the bags. These images or parts of the images can then be compared in a computing and control unit with other data, such as target data of the bag. However, such further data may also be images or parts of images taken from the same or from another sack. Detects the computing and control unit due to the comparison of a bag as faulty, it can control the deflector accordingly, so that the bag is discharged.
  • the invention is in addition to the device described also a method according to claim 8.
  • Fig. 1 shows components of a device 1 according to the invention, which are arranged behind the rollers 2 and 3 as seen in the transport direction x. To understand the function of these rollers is based on the patent application DE 101 04 002 referred to the applicant. In the figures shown there, these rollers carry the reference numerals 6 and 4.
  • the connecting line between the axes of rotation of the rollers 2 and 3 is substantially vertical to the transport direction x of the bags (ie in the drawn direction y).
  • the rollers 2 and 3 Form the nip for pressing the ground cover sheets with the bottoms of the bags, as already described above.
  • the bag 4 is shown by way of example.
  • the bag 4 is transported by the transport belts 5 and 6 of the double belt conveyor 7 and rests on the surface of the table 8.
  • the upper strand 9 of the conveyor belt 6, which is generally referred to as an empty strand, is greatly spaced from the lower strand 10 in the direction y.
  • a deflection means 11 is arranged behind the double belt conveyor.
  • This comprises at least one lifting cylinder 12, preferably a compressed air cylinder, with which a plunger 13 in the direction of the double arrow A can be raised.
  • the plunger In its raised position, the plunger is introduced into the conveying path and deflects the bag from the original transport direction x.
  • the bag slides, further advanced by the double belt conveyor 7, along the plunger 13 until it enters the inlet gap of the double belt conveyor 14 and is gripped by this and fed to a collecting or transporting device.
  • the plunger 13 releases the further transport path in the transport direction x, so that the bag 4 can reach the transport device 15, which removes the bag in the direction z, which runs essentially at right angles to the original transport direction x ,
  • the lifting movement of the plunger 13 can be triggered manually when the operator detects a faulty bag 4.
  • the table 8 may comprise a transparent surface, are arranged under the lighting means. Thus, they illuminate the bag 4, so that the operating personnel who inspected the bag from above can better recognize production and / or material defects compared to the visual inspection that was previously carried out on machines of the prior art.
  • the distance from the lower run 10 arranged Obertrum 9 facilitates the observation of the bags, since it provides sufficient space for this.
  • the Fig. 2 represents the already described situation in the supervision.
  • the comparison of the Figures 1 and 2 shows that the rollers 2 and 3 are each divided into individual rollers 2 and 2 'and 3 and 3', respectively, which only come into contact with the end regions of the bag 4.
  • the floors 16 are folded into the transport plane of the bags 4. In this way, the heat introduced into the bottoms 16 during manufacture radiates substantially upwards.
