Definitions
- the invention relates to a machine for continuously sealing a bottom or a cover on the edge of a section of profile, in particular of tubular profile used as packaging and obtained by gluing several strips of material.
- fibrous, cellulosic, metallic, plastic and other, machine having, on the one hand, a frame composed of a base containing the various mechanical, electrical, electronic, pneumatic and other apparatus ensuring the functioning of the machine and of two vertical parallel supports arranged at the two ends of the base between which is placed a cyclically rotating drum of polygonal section, each side of which is provided with means for gripping and holding the sections of tubular sections, successively cooperates with assemblies comprising an assembly for introducing the sections of tubular profiles, a gluing assembly, a supply and bottom placement assembly, an evacuation assembly, said sets tiles being distributed concentrically with respect to the drum.
- This machine also includes a forming device cooperating with a drive and pinching mechanism to continue and widen the bonding area, a train of pressure diabolos allowing the finishing of the tubular profile and in particular the end-to-end bonding of the lateral edges of the bands.
- the machine comprises a device for cutting multiple peripheral cuts supplemented by a device for discharging the sections of the tubular section sectioned by the cutting elements of said cutting device.
- document FR-A-2 181 425 discloses a machine for sealing a bottom or a cover on the edge of a section of profile corresponding to the preamble of claim 1. Its assembly d gluing does not take effect until the bottom and cover have been inserted into the end of the profile section.
- This bonding assembly comprises a vertical cylinder actuating a vertical rod sliding in a guide.
- This vertical rod has at its upper end an annular part picking up glue from a container.
- the upper edge of this annular part wet with adhesive by immersion engages in the section of section to deposit a thread of adhesive on the disc introduced into the end of the section of section.
- the outside diameter of the annular part must be slightly smaller than the inside diameter of the end of the profile section. If there is a manufacturing or mounting defect on the gripping device, either the annular part cannot penetrate into the profile section, or the deposit of the adhesive stream is not uniform on the edge of the disc. Finally, the cover or bottom is held by clamping inside the profile section, which risks deforming the flatness of the cover or the bottom.
- the present invention aims to remedy these drawbacks.
- the invention as characterized in claim 1, solves the problem of creating a continuous sealing machine for a bottom or a cover on the edge of a section of profile, in particular of tubular profile used as packaging and obtained by gluing several strips of fibrous, cellulosic, metallic, plastic and other materials, machine having, on the one hand, a frame composed of a base, enclosing the various mechanical, electrical equipment , electronic, pneumatic and other ensuring the operation of the machine and two vertical parallel supports arranged at the two ends of the base and between which is placed a cyclically rotating drum of polygonal section, each side of which is provided with means for gripping and holding the sections of tubular sections successively cooperate with assemblies comprising a set for introducing the sections of tubular sections, a sizing assembly, a set supply and placement of funds, an evacuation assembly, said removable assemblies being distributed concentrically with respect to the drum and the sizing assembly of which comprises a vertically movable frame composed of two longitudinal members
- the advantages obtained thanks to this invention consist essentially in that the adhesive film is deposited on the edge of the profile sections by glue plates mounted in a flexible manner whose contact with the edge of the profile sections is absorbed while avoiding the deterioration of said edge.
- the type of mounting of the gluing plates makes it possible to compensate for a defect in the perpendicularity of the edge of the section with respect to its axis.
- the flexible mounting of said sizing plates not only allows uniformity of the adhesive film over a single section since the contact between the sizing plates and the section of section is made over the entire edge of the latter, but also a uniformity of the adhesive film on the edges of the row of sections.
- the adhesive film is removed before the cover or bottom is put in place, so that the latter is held without any deformation as soon as it comes into contact with the glued edge of the profile section.
- the machine 1 for continuously sealing a bottom on one of the edges of a section of tubular profile obtained by gluing several strips of fibrous, cellulosic, metallic, plastic and other materials comprises a frame 2 composed of a base 3, containing the various mechanical, electrical, electronic, pneumatic and other apparatus ensuring the operation of the machine 1, and of two vertical parallel supports 4 disposed at the two ends of the base 3 and fixed to this base 3 by any means.
- a polygonal section drum 5 subjected to a cyclic rotation movement and several assemblies 6, 7, 8, 9, 10, 11, 403, 404, 449, 533, 572, 614 being able to be the if necessary, interchanged. These assemblies are arranged parallel to the drum 5 on a circle concentric with said drum 5.
- the first set 6 is a set for the introduction into the machine 1 of the different sections of tubular section of polygonal section to be provided with a bottom, this introduction being done by row of sections.
- the second assembly 7 is a preforming and heating assembly for the end of the section of tubular section on which the bottom will be disposed. Indeed, it may very well be that during the handling of the different sections from the exit of the forming machine to the machine 1, these are deformed. Therefore, it is necessary to restore this end to its original shape. In addition, this assembly 7 also makes it possible to standardize the opening of this section because the section must be strictly identical for all the same sections. Otherwise, there is a risk either that the bottom passes through this opening, or that it is placed askew and assembly cannot be done.
- the third set 8 is a sizing set. In this set, the glue is placed on the edge of the section.
- the fourth set 9 allows the supply and the establishment of the bottom.
- the fifth assembly 10 may consist of a crimping assembly. If necessary, this fifth assembly is removed and, at this location, the section can be subjected to accelerated drying.
- the sixth assembly 11 is an assembly allowing the evacuation of the sections provided with the bottom.

- Each flat surface 12 to 17 has at its two ends 35, 36 a longitudinal boss 37, 38. There are between these longitudinal bosses rows of gripping means 39 fixed by any means 40.
- These gripping means 39 are shown in Figures 4 and 5. They comprise a base plate 41 which is received between the bosses 37, 38.
- the underside 42 of this base plate 41 has a groove 43 serving as a conduit for a fluid such as compressed air.
- This groove 43 is closed by a tight cover 44 disposed in a housing 45 terminating in the groove 43 and held in place by fixing means 46, 47.
- the groove 43 is connected to a fluid distribution network (not shown) by an opening 48 made in the base plate 41.
- the groove 43 is connected, by openings 49, produced at regular intervals, to cylinders, preferably pneumatic 50 made integral with the top 51 of the base plate 41 by fastening elements 52, 53, 54, 55.
