Definitions

  • the invention relates to a gluing machine in a corrugated cardboard system according to the preamble of claim 1.
  • a gluing machine in a corrugated cardboard plant has the task of activating the glue between sheets arranged one above the other and bringing about the gluing.
  • the gluing machine has heating plates which are heated with steam, for example.
  • the sheets to be glued one above the other are moved along the surface of the heating plates and pressed against the heating plates with the aid of pressing means. This is done, for example, with the aid of a belt and / or rollers, but also with the aid of compressed air that is generated within a hood, which is placed above the heating plates.
  • a gluing machine is usually divided into a heating section and a pulling section.
  • the pulling section serves primarily for the translational movement of the corrugated cardboard, with cooling inevitably taking place in this area since heating is not carried out. It should be disregarded in the following considerations.
  • the gluing machine is used to glue a single-shaft, single-sided sheet to an outer cover sheet.
  • both webs are passed over preheating cylinders, and the one-sided web is provided with glue in a coating unit, more precisely, the shaft tips of the one-sided web are coated with glue so that the outer cover web can be glued to the shaft tips.
  • two or three one-sided webs have to be connected.
  • the one-sided webs are each guided separately, in parallel, via a preheating cylinder and an applicator unit, the outer cover web being guided to the gluing machine in the manner described above.
  • the heat of the heating plates must penetrate the outer cover sheet in order to obtain the glue.
  • the heat With multi-walled cardboard, the heat must be passed over the outer cover sheet and at least one one-sided sheet to get to the glue between two one-sided sheets.
  • the thermal conductivity of paper is not particularly good. A greater thermal resistance is formed by a web that is corrugated on one side, in which the corrugation is only in line contact with the cover webs. It therefore takes a relatively long time until, in the case of multi-walled cardboard, a sufficient temperature is also established within the layers in order to achieve the desired activation of the glue.
  • glues that can be activated even at lower temperatures, but these are relatively complex and expensive compared to conventional glues.
  • the loading rollers for the belt below the heating zone are also disadvantageous in the known gluing machine. They require additional effort or energy and special design measures.
  • the division of the heating section into different heating zones is exclusive in the known gluing machine due to the necessary subdivision of the weighting device or weighting belt.
  • the weight belt is located above the heating zone and in the second heating zone below.
  • the division of the weight belt requires additional drives and corresponding controls, which increases the outlay on equipment.
  • the invention has for its object to provide a gluing machine in a corrugated cardboard system, which allows to produce multilayer corrugated cardboard with high production speed with little equipment and inexpensive heat.
  • the pasting machine according to the invention or its heating section is divided into at least two sections which are spaced apart from one another in the working direction.
  • an applicator is arranged below their working level, which interacts with the underside of the bottom web.
  • a feed means is also assigned to an intermediate space for feeding a web to the next section.
  • a gluing machine of this type either a one-sided web and a cover web are fed into the first heating section or two one-sided webs are fed. If, for example, a double-corrugated cardboard web is to be produced, the outer cover web is first introduced into the subsequent second heating section.
  • the applicator arranged in the space between the heating sections carries the glue onto the shaft tips of the lower sheet, so that the cover sheet in the subsequent heating zone section with the lower one-sided sheet can be glued. If a three-corrugated cardboard is to be produced, the third one-sided web is fed in the space between the first two heating sections, while the outer cover sheet is fed in the space between the second and third heating sections.
  • the feeding of the single-sided corrugated cardboard and the cover sheet one after the other and over the length of the gluing machine enables higher production speeds to be achieved.
  • the heat required to gel the glue does not have to be applied at once for all the papers to be bonded, rather the heat application process takes place in stages.
  • This advantage is obtained without the overall length of the gluing machine having to be increased significantly.
  • the gluing machine according to the invention favors the processing of printed and in another form surface-treated outer cover sheets. The reason is that these webs with their sensitive surface do not have to be drawn over all heating plates for an unnecessarily long time. They are therefore not exposed to the relatively high pressure and heat in the first sections of the heating plate. A significant increase in quality is therefore obtained.
  • an embodiment of the invention provides that the height of the application unit arranged in the intermediate space is adjustable.
  • the applicator is expediently constructed in such a way that the glue application roller protrudes somewhat with its circumference from the plane of the heating plate surface. If the application unit is not required, it is adjusted downwards by a small amount so that it disengages from the lower track. It goes without saying that instead of a total adjustment of the application mechanism, an adjustment of the application roller is also possible.
  • the supply means have a heating cylinder or the like.
  • a heating cylinder By arranging a heating cylinder immediately in front of a heating zone section, only a slight cooling occurs between the heating cylinder and the heating zone section, so that the latter must heat the assigned web to a lower temperature than is the case, for example, in the prior art, in which the heating cylinders are located in front of the application unit and are therefore at a relatively large distance from the gluing machine. In the pasting machine according to the invention, less thermal energy is therefore required compared to the prior art.
  • an application unit and a preheating device can be assigned to the first heating zone section.
  • a further embodiment of the invention provides that two preheaters and an applicator are arranged upstream, one preheater is connected upstream of the applicator and the other preheater is arranged directly at the beginning of the heating zone. Only a heating cylinder therefore needs to be arranged at a certain distance from the gluing machine.
  • the upstream application mechanism is also expediently adjustable.
  • the lower one-sided web with the corrugation is placed against the heating plates in the case of two- or three-ply cardboard.
  • the heating plates run transversely to the working direction. With this cross arrangement there are discontinuities between the heating plates and can possibly affect the curl. Therefore, an embodiment of the invention provides that parallel heating plates extend in the heating zone sections in the longitudinal direction. In this way, there are no discontinuities in the heating zone sections where the waves can be damaged.
  • the first one-sided web is fed directly to the first heating section and the associated cover sheet via a preheating cylinder in the space between the first and second heating sections.
  • an upstream application unit or an upstream preheater is eliminated.
  • the space required by the application unit and the preheater is therefore fully available for the subsequent system.
  • a gluing machine 10 in a corrugated cardboard system has three heating zone sections 11, 12 and 13, which are arranged on a base 14. Spaces 15 and 16 are provided between these.
  • the parallel heating plates extend in the working direction, ie in the direction of the arrow 16.
  • an applicator 17 is arranged, the applicator roller 18 of which forms the highest point of the applicator 17.
  • the height of the applicator 17 is adjustable, as indicated by the double arrow 19.
  • a second application unit 20 is arranged in the intermediate space 16. It is also adjustable in height according to double arrow 21.
  • the first heating zone section 11 is preceded by an applicator 22, the position of which can also be changed in accordance with the double arrow 23.
  • a preheating cylinder 24 is arranged upstream.
  • a second preheating cylinder 25 is arranged directly in front of the heating zone section 11 below its working level.
  • Pre-heating cylinders 26, 27 are arranged in the spaces 15 and 16 and are also below the working planes of the assigned heating zone sections 12 and 13, respectively.
  • the pasting machine shown works as follows.
  • the application unit 22 is supplied with a web 30 that is corrugated on one side via the preheating cylinder 24 (also indicated by the circle 31). If only a single-shaft web is to be produced, a cover web is fed via the preheating cylinder 25, which is glued in the usual way to the one-sided web 30, the latter being provided with glue with the aid of the applicator 22.
  • a load belt 50 is arranged as an endless belt with its working strand above the heating zone sections 11, 12 and 13 in order to press the webs against the heating zone sections.
  • a twin-shaft web is to be produced, a second one-sided web 33 is fed in via the preheating cylinder 25, also indicated by the circle 34. In the heating zone section 11, two single-sided webs are therefore glued to one another to form a double-shaft web 35, indicated by the circle 35.
  • the cover sheet which is glued to the twin-shaft sheet 35, is fed in via the preheating cylinder 26.
  • the third one-sided web 37 is supplied via the preheating cylinder 26, also indicated by circle 38.
  • the cover web 39 is then supplied via the preheating cylinder 27, also indicated by a double circle 40.
  • the three-shaft path 41 is formed, also indicated by circle 42.
  • the individual webs are fed in successively, so that the heat generated by the heating zone sections 11, 12 and 13 only has to penetrate a cover layer or a one-sided web in order to reach the bond point.
  • the application units 17 or 20 will not required, they are adjusted out of engagement with the assigned path.
  • all the webs to be introduced into the spaces 15 and 16 are fed in the working direction below the gluing machine. It goes without saying that these webs can also be fed laterally by means of corresponding deflection rollers.
  • the first heating section 11a is preceded by a heating section 111 which is structurally similar to the other heating sections 11a, 12a and 13a. It is arranged at a distance from the heating section 11a and thus forms an intermediate space 112, in which an applicator 113 with an applicator roller 114 is arranged. The height of the applicator 113 can be adjusted according to double arrow 115.
  • a heating cylinder 116 is arranged in the space.
  • the one-sided web 30a (shown in circle 31a) is fed directly from the bridge to the first heating section 111.
  • the cover sheet 33a on the other hand, is fed in below the first heating section 111 and placed over the heating cylinder 116 against the underside of the first one-sided sheet and glued to the heating section 11a. If, on the other hand, two- or three-corrugated corrugated cardboards are to be produced, the second or lower one-sided web is fed to the second heating section 11a via the heating cylinder 116.
  • the advantage is obtained that the outer cover sheet is heavily protected and can therefore be pre-printed or treated in a different way in a favorable manner.
  • the applicators according to the embodiments of FIGS. 1 and 2 can not only be height-adjustable but also laterally adjustable, for example to move them out of the gluing machine for cleaning purposes.
