Definitions
- the present invention relates to a system that allows the gluing of sacks or paper bags composed of several layers or sheets and, in particular, the gluing of their bottoms.
- the object of the invention is a glue applicator cliché, used for gluing the bottoms of the sack and, in particular, a special relief of the aforementioned cliché that prevents detachment of the tail at high speeds.
- Sacks or paper bags composed of several layers or sheets are formed from paper reels, and sometimes also of plastic materials, in two main phases, a first phase of formation of a tubular surface open at its ends and a phase of formation of the funds and, therefore, of the sack itself. To do this, first of all, some glue points are applied that are located at the edges of the leaves. This gluing is necessary to hold together the sheets that constitute the sack, during the operations of folding and gluing the funds.
- a glue is applied on the longitudinal edges of the sheets to form a closed tubular surface.
- the sack bottoms are formed, which are obtained by folding and gluing defined flaps at the ends of the previously obtained tubular surface.
- gluing points are those that have been mentioned first, since they are applied at the beginning of the sack forming process.
- transfer rollers are used that direct the adhesive to an applicator roller that has on its surface a cliché or special band of rubber or similar of rough surface, with small alveoli in which the queue transfers to the flaps of the sheets of paper for closing, thus forming the sack bottoms.
- the gluing machines have applicator rollers that have strips on which glue points are fixed that apply the glue on the front and rear mouths. of the different layers or sheets.
- the glue points are made of rubber, plastic or metal and generally have a circular, elliptical or rectangular configuration.
- glue points can be part of the strip or constitute independent and interchangeable pieces that are coupled to the strips through a support provided with a lower shaft that is threaded to said strip and an upper shaft in which it is threaded the glue point.
- the sizing system object of the invention solves the problem mentioned in the forming of the bottoms of the bags, as regards the gluing of the flaps and reinforcement strips of the bottoms, as well as the sizing of the different sheets of each bag that allow to keep them together during the funding or formation of the funds.
- the cliché for gluing the flaps of sacks or paper bags that constitute the object of the invention is made of plastic or similar material and shows a special relief on its surface that allows the current problems to be satisfactorily resolved.
- the relief of the cliché surface is formed by a series of parallel rows that make up a series of ridges, among which the corresponding valleys or grooves are defined, so that the tail is distributed by impregnating only the ridges, avoiding its detachment at high roller rotation speeds.
- the rows of ridges are arranged longitudinally in the direction of rotation of the applicator roller.
- the tail is applied by forming a series of parallel lines, the distance of which is determined by the separation between the ridges and which can vary according to the type of tail used and the required needs. The cleaner the tail is and the greater its wet grip, the better results are obtained.
- This morphology allows a better distribution and saving of glue and much less splashed, so that drying occurs more quickly and therefore can increase productivity and reduce the terms of delivery of the bags obtained.
- the ridges can have different configurations, such as triangular, wavy, square, trapecial profiles. Special configurations are also planned, such as parallel rows of pairs of truncated conical protuberances that allow the amount of glue used to be further reduced. In addition, this configuration allows to retain the tail in the cliché at the machine stops, so that when the movement is restarted, the glueing of the funds occurs without interruptions or areas without tail.
- some glue points are used whose design facilitates the impregnation of glue and its application in the forming of bags preventing it from accumulating.
- the glue point when the glue point is metallic, an essentially triangular configuration is provided, the glue point being arranged on the corresponding strip oriented so that one of the vertices of the triangle faces the direction of the tail.
- the gluing point can be provided with a longitudinal channel or groove that crosses it through its central part to improve the evacuation of the tail.
- the glue points are made of rubber or plastic, they are expected to have a circular sector configuration, the vertex of the latter being facing the direction of the tail. This circular sector may also incorporate a central groove similar to that described above.
- the glue points of rubber or plastic can also have a circular segment configuration, of reduced thickness, which faces the direction of the glue through its curved edge that presents less resistance.
- Figure 1. Shows some of the phases of forming a multi-sheet bag or bag.
- Figure 2. Shows a series of profiles, corresponding to various configurations of the cliché surface for gluing the sack bottoms.
- Figure 3. Shows a perspective of a cliché composed of pairs of rows of frustoconical protuberances.
- Figure 4. It shows a plan view of a strip in which the gluing points of the multiple sheets constituting the bag are arranged, with triangular configuration points having been represented.
- Figure 5. Shows a perspective view of a possible geometric configuration of the glue point of the multiple sheets that they constitute the sack and, in particular, of a triangular configuration glue point.
- Figure 6. Shows a perspective view of a possible geometric configuration of the glue point of the multiple sheets that constitute the sack and, in particular, of a glue point of configuration in a circular sector.
- Figure 7.- Shows a perspective view of a possible geometric configuration of the glue point of the multiple sheets that constitute the sack and, in particular, of a glue point of circular segment configuration of reduced thickness.
- Figure 1 shows a bag of multiple sheets in different phases of its forming and, in particular, the following: a.- A sheet of paper (1), once the glue is applied at its extreme edges. On this sheet another sheet of paper is placed, both being held together through the aforementioned tail points (2), to allow subsequent gluing of the bottoms. This glue is applied by means of the glue points (3) that are the object of the invention. b.- A bag (4), once a longitudinal glue line is applied on both sheets, achieving a tubular configuration open at its ends. c- A bag (4), once configured one of the flaps (5) of the bottom and applied the corresponding tail (6) on it. This glue is applied by the cliché (7) object of the invention.
- the gluing points (3) represented in phase a of Figure 1 allow the multiple sheets (1) that constitute the sack (4) to be glued together and, as seen in Figure 4, are of type of those that are mounted on a strip (8) which in turn is arranged on an applicator roller and the glue points (3) can be mounted on the strip (8) interchangeably, through the corresponding threaded support.
- the gluing points (3) object of the invention can have different configurations depending on the material from which they are constituted.
- the metal glue points have an essentially triangular geometry (3 ') and are arranged on the strip (8) so that one of its vertices is facing the glue direction, as seen in figure 5.
- the glued points of rubber or plastic are formed in the form of a circular sector (3 ") with their vertex facing in the direction of the glue, as shown in figure 6 .
- the rubber or plastic gluing points may have a circular segment geometry of reduced thickness (3 '"), the circular segment being supported vertically on the strip (8) through its rectangular base and so that it attacks the tail with its side of shorter length, approximately 2 mm.
- This glue point (3 ') is shown in Figure 7.
- the glue points (3 '), (3 "), (3'") are provided to have a longitudinal groove (5), as seen in Figures 5 6 and 7.
- the cliché (7) object of the invention consists of a piece of plastic or similar material comprising a series of parallel rows (10) defining respective ridges and valleys or grooves, so that the adhesive permeates only the ridges and the application of glue on the flap (5) and reinforcement strip (13) It is produced by forming parallel lines (6). In this way, a saving of glue is achieved that leads to a faster drying and an increase in production.
- the parallel rows (10) are arranged in the direction of rotation of the gluing roller.
- the parallel rows can have various configurations, as can be seen in Figure 2, in which rows with triangular, wavy, trapecial or square profiles have been represented.
- Figure 3 shows another embodiment for the cliché (7) comprising a series of rows (11), composed of pairs of truncated conical protuberances (12) that further reduce tail consumption and also retain the tail in the cliché (7) when a stop occurs machine.
