The invention relates to a method of forming a tubular body from a flat packaging blank consisting of four wall areas divided by parallel fold lines, according to which the opposite free, heat-sealable edge zones of the blank are heated and the blank is folded into folds to overlap the heated surfaces. the heat-sealed blank is raised into a tube, the two outer regions being raised to form an angle with the central regions to allow the outer regions to be heated so as to move the raised outer regions past devices to heat the outer regions to be folded down and then folded down the heated edge zones overlap and compress with each other, and cooled to ensure permanent adhesion.

The apparatus according to the invention, with which the above-mentioned method is implemented, comprises a device for heating the heat-sealable edge zones of the sheet and a device for setting and sealing the heated edge zones together and a device for forming a body sealed in this way from the edge zones into a rectangular can.

2 60162

The sheet, which is formed as a can body in the above-mentioned manner, may comprise walls (they form the side walls of the finished can) which are "hinged" along the fold lines notched in one sheet. In addition, a conveyor device can be provided in the apparatus for feeding a can sheet parallel to the above-mentioned folding line through the apparatus. Immediately following the above steps, the apparatus may comprise a) a device for lifting the can sheet up from the feed stack and keeping its outer walls higher than the rest of the sheet, b) a device for heating the sealable edge zones of the upright walls of the sheet, c) a device for folding and overlapping the two outer walls , d) a device for bending the side walls of the tubular can body in the respective manner, the tubular can body being formed by joining the edge zones to form a body rectangular for the next step.

The method according to the invention is characterized in that the vertical lifting of the edge-sealed blank into a square-shaped tubular body is carried out by rotating said areas relative to adjacent areas along corresponding folded injections and the blank folded into a flat blank in one flat folding plane is formed and preformed. in its second flat folding plane, wherein the wall areas, after said second flat folding, are located substantially perpendicular to each other and form a tubular, open-ended packaging body.

The understanding of the invention will be facilitated by the following description of an embodiment (shown only by way of example) according to which a can can be manufactured. It will be easier to follow the description if the reader is familiar with the following drawings, in which Fig. 1 shows a top view of a can sheet which can be used in practicing the invention, Fig. 2 shows a slightly simplified or schematic perspective view of an apparatus for forming the sheet of Fig. 1 into a tubular can body , Fig. 3 shows a top view of the 1st feed end of the rear of the machine shown in Fig. 2, Figs. 4 and 5 show side views of the machine part shown in Fig. 3 in different operating positions, Fig. 6 shows a second heating section of the apparatus shown in Fig. 2 in a transverse vertical section, with the sheet to be viewed in that feed direction , Fig. 7 shows a side profile of the part of the apparatus shown in Fig. 6 and a sealing section 1 following the apparatus, Fig. 8 shows the sealing section of the apparatus shown in Fig. 7 in cross-section with the sheet visible in that feed direction, Fig. 9 shows the sealing section shown in Fig. 2 hardware section side profile 3 601 62

A sink in which the can body is made rectangular after edge sealing, and Figures 10 and 11 show cross-sections of the "square part" shown in Figure 5 in different operating positions.

When the invention is applied in a suitable manner, as can be seen from the above figure, here a device is required for forming a can sheet into a tubular can (made of e.g. plasticized cardboard), i.e. a device according to Figure 1. The can then comprises four walls 1,2,3 and 4 and a sealing strip 5 »which always join the adjacent walls at their side edges and which are" articulated "together along the fold lines 6 and which have opposite end flaps 7» bounded by the fold lines, which close the ends of the can, when the can is finally in size 1. "upright".

Figure 1 shows a first step of processing the sheet, which involves attaching a sealing strip to the free edge of the opposite wall 1 to form a tubular body in which the flaps 7 protrude from the opposite ends of the can sheet. The present invention therefore relates precisely to this step of assembling a can.

Figure 2 shows a simplified embodiment of the apparatus according to the invention. It consists of four compartments intended to operate in succession and to process a sheet fed into the apparatus (in the direction of the arrow shown in Fig. 1) by a suitable conveyor device.

In section A of the apparatus, the side walls of the top can sheet of the sheet stack are folded up along the fold lines therein. The retaining bars thus hold the raised side walls upward as the sheet moves to compartment B.

As the sheet passes through compartment B, the rollers hold the side walls of the sheet up while the plasticized edge zones of the sheet are pre-heated for sealing.

The sheet then moves to compartment C, while another set of rollers holds its side walls up so that the heated edge zones of the walls overlap, after which the thus bent sheet goes between the compression betels, which firmly press the seam of the sheet edge zones together.

The folded and seamed can sheet from compartment C moves flat to compartment D, which has a device for bending the side walls 1,2, 3 and 4 correctly at the bending lines 6 in the sheet and to form the sheet into a rectangular tubular can body, which then moves to the next working step. and sealing machine.

Figures 3, 4 and 5 illustrate the methane parts of the folding section A of the apparatus. The can stack of cans shown in Figure 1 is supported by four corner posts 10. The columns then form a body located inside the main body 11 of the apparatus. The shafts 12 are placed with suitable bearings in the rear transverse reinforcement of the main body 11 and support the swivel plates 13 · From each of the 4 60162 swivel plates 13 a rotating tube 14 «is directed forward - apart from the shaft 12 - to which another tube 15 is fitted. above the top sheet of the sheet stack 9. The rear end of the tube 14 is attached to a plate 17 provided with a spring, which allows the suction cup unit to rotate somewhat and also to concentrate. The tubes 15 are connected to a suction removal device (not shown in the figure), so that due to this operation the cups 16 can adhere to the top sheet of the stack 9. As shown in the figure, the cups are placed above the outer walls 1 and 4 of the sheet.

The shafts 18 are secured by cantilever bearings to the side portions of the body 11, each supporting an arm 20 at each end. Between the outer ends of the arms 20, a retaining roller rod 21 is mounted in each, extending substantially the entire length of the can sheets. The rear arm 20 of each such retaining unit is located next to the pivot plate 13 of the corresponding suction cup unit and connected to it by an adjusting joint 22.

Figure 4 shows the beginning of a work phase. The suction cups 16 are then against the outer walls 1 and 4 of the top can sheet 9 of the stack 9. Suction is applied to the cups 16, whereby they engage the sheet and the shafts 12 rotate, thereby turning the plates 13 and thus bending the sheets 1 and 4 of the sheet at a bending line in the sheets to a vertical position, as shown in Fig. 5. At the same time, due to the movement of the joints 22, the arms 20 turn downwards, whereby they move the retaining rods 21 against the outer surfaces of the upright can wall walls 1 and 4. When the suction of the cups 16 is released, the walls 1 and 4 detach from the cups, but remain at the top held by the rods 21 (Fig. 5) ·

The support portions 10 of the transverse can sheet stack each have a substantially triangular plate 23 (Figure 3) which overlaps the leading edges of the top sheet. As the suction cups lift the walls 1 and 4 of the top sheet upwards, the corner of each wall bends and bypasses the plate 23 which grips the next sheet of the stack and prevents two sheets from rising out of the stack at the same time.

Mounted at the center of the rear transverse portion of the body 11 is a hydraulic device 24 «which reciprocates in the pusher 25, up to which the top sheet of the stack advances when its side walls 1 and 4 are raised, as shown in Fig. 5. When the pusher 25 has had some time to carry the sheet, the traction rollers 26 lift the sheet up and move it to the point where the finger 27 in the "endless" chain 28 lifts it up. Chain 28 then moves the sheet forward. The traction rollers 26 have corrugated surfaces formed of plastic, rubber, etc. rings and mounted on a cylindrical body.

The sensor member 42 (Fig. 7) resting on the upper surface of the stack 9 gives a signal when the sheets start to move out of the stack, whereby the compressed air lift 43 starts. Ko. the lifter lifts the bridge that supports the stack The upper surface of the stack 60162 5 then remains in line with the pusher 25.

When the sheet walls 1 and 4 are upright, as described above, and when the pusher 25 has moved the sheet forward, it moves from the compartment A of the machine to the compartment B shown in Figs. 6 and 7 ·

A series of fixed spindle rollers 29 which are vertically substantially at the same angle as the angle at which the retaining rods 21 hold the sheets 1 and 4 of the sheet are attached to each side of the machine body. When the upright walls 1 and 4 of the sheet have detached from the retaining rods 21, po. the rollers grip them and hold them at substantially the same angles throughout the time the sheet and the the walls move forward in the device.

Two spaced apart bridge sections 30 extend over the sheet travel path. In the central part of each bridge there is a downwardly directed leg 31 »which supports at its lower end a bridge 32 with a spring, with side rollers 33» which hold the central walls 2 and 3 of the sheet in the lower rollers 26.

Heaters are provided on the supports attached to the bridges 30 to soften the plasticized edges of the sheet. The heaters are directed to one of the surfaces of the can sheet to be sealed, with one heater 34 directed towards the outer edge of the sealing strip 5 and the other heater 35 again directed towards the inner surface of the edge zone of the wall 1 which is bent over the strip 5. For example, gas burners are suitable heaters. The gas then comes to them from the pipes that generate the gas jets that heat the sheets. The burners can also be used.

As the sheet passes through compartment B, the heaters 34 and 35 heat the edge zones 1 and 4 of the walls to such an extent that the plastic layer therein softens or melts, causing the heated portions of the sheet to be suitably sealed together. At this point, the sheet goes into the compartment C of the apparatus (Figures 7 and 8) and passes over rollers 37 supported on the rails of the lower plate 38 of the body. As the sheet moves forward, the side rollers 39 prevent it from moving laterally.

Extending over each side of the bottom plate 38 in the direction of travel of the sheet is a shaft 40 which rotates about an axis circumference. The lower plate is further associated with spaced apart support rollers 41 * which are substantially similar in shape to the rollers 29. As the shaft 40 rotates, the rollers 41 move between their upper and lower positions. When the rollers are in their upper position - shown by the dotted lines in Fig. 8 - they are in an inclined position and in line with the rollers 29. When the bulls 41 move to their rla position, they are substantially horizontal (solid lines in Fig. 8). As the rollers 41 move from their upper position to their lower position, they fold down the walls 4 and 1, whereby the edges of the sheet overlap, and the edge zone of the wall 1 contacts the outer surface of the sealing strip 5. It should be noted that when the sheet moves from the compartment B of the machine to the compartment C, the rollers 26 lift it up by means of chain fingers 27, as a result of which the sheet moves to the next process.

When the sheet is thus bent, it passes between compression rollers 44, 6 60162 which cause the softened plastic to adhere firmly to the edges of the walls 1 and 4. When the sheet is thus bent, it also moves around a circular cooling drum 45 into which it is pressed by rollers 46. The drum 45 can be cooled by an internal water circulation system (not shown), whereby the plastic seal of the sheet is hardened.

The sheet then moves on rollers 47 to the machine compartment D # (Figures 9, 10 and 11). The purpose of compartment D is to soften the stiffness of the folds of the sheet walls 1,2,5 and 4 (the walls are already sealed at this stage) and to make the sheet "rectangular" so that it can be transferred further (e.g. to a packaging machine) as an open, tubular can body. To this end, the compartment D is intended to press the opposite, bent edges of the flat bent sheet together. The sheet enters the compartment D mainly horizontally (solid line in Fig. 10), 'a leaving further mainly in the vertical plane (dotted lines in Fig. 10).

The device then opens the articulated sheet walls into a square tube (Figure 11). The body of the compartment D comprises opposing side bars 48 and 49 which are arranged in the direction of travel of the sheet and which slide back and forth relative to each other, i.e. towards each other and then apart. The inner surfaces of the wedding side bars 48 and 49 have grooves 50, and as can be seen in Figure 10, the folded edges of the sheet slide into the grooves 50 as the sheet moves away from the compartment C of the apparatus.

Suspended below the side bar 48 is a spring-loaded compression foot 51 »with a suction cup 52 inside. The suction cup 52 is connected by a pipe 55 to a suction removal device. A compression support device 54 is also mounted under the side bar 49. · When the flat bent and seamed sheet has moved 50, the side bars 48 have moved towards each other with the result that the top horizontal walls 1 and 4 of the sheet turn up and push together, while the bottom walls 2 and 5 turn down and push together in the same way. Po. the switching operation is shown from the initial position shown in solid line in Fig. 10 to the switching position shown in dotted line, where the lower walls 2 and 5 are pressed together between the presser foot 51 and the support device 54.

In this position, the suction device 52 begins to operate and the rods 48 and 49 move apart. As a result, the wall 5, which is then in a vertical position, moves laterally (to the left, as shown in Fig. 10) to the outer rest position of the suction device 52.

The plate 55 is arranged to pivot into the side bar unit 48 and connected movably to the joint 56. · When the rod 48 moves towards the rod 49, the joint 56 causes the plate 55 to rise from its "closed" position (solid line in Figures 10 and li) to a vertical position (dotted lines in Figure 10). When the rod 48 has retracted and retracts the sheet wall 5 by means of a suction device 42, the plate 55 automatically pivots downwards by its hinges under the action of the joint 56, 7 60162 gripping the wall 4 and bending it down to a "rectangular position", e.g. at right angles to the wall 3 (Figure 11). Due to the change of the walls 3 and 4 to the quadrangular position, the opposite walls also come into the same position, whereby the sheet becomes a tubular body of rectangular cross-section, as shown in Fig. 11; It should be noted that to facilitate these folding movements, the grooves 50 are quite wide and have rounded corners into which the bent edges of the sheet go. The pre-sealed and tubular can is then moved out of the apparatus, as shown in Figure 2, to the next step, e.g. a packaging machine. The exit of the can from the apparatus is guided on one side by a pressing part 51 and on the other side by a series of truncated cone-shaped guide rollers 57 ·

The various parts of the apparatus described above are powered by a uniform drive by means of a gear 58. The gear is driven by a chain 59 connected to an external power source. The drive device also includes a gear 60 which drives a chain or belt 61 disposed on the gears or pulleys 62a and 62b adjacent to section D of the apparatus (Fig. 9). Associated with the gear 58 is a cam gear 63 with which a push cam 64 moves. The push cam 64 is mounted on a lever 65, which in turn is fixed to a shaft 66 which is held in place by a spring device 67, whereby the push cam remains attached to the cam wheel.

Both side bars 48 and 49 are mounted on a so-called on a carriage moving back and forth between the rollers 69 to the machine body at 71 under the control of an articulated cam lever 70. Each carriage 68 is connected to one part of the angular lever arm by an adjustable joint 72 (Fig. 10), while the other part of each angular lever arm is connected by an adjustable joint 73 to a corresponding lever 65 mounted on the shaft 66 and driven by a cam wheel 58, as mentioned above. During each rotation of the camshaft, loosening of the edge compression allows the levers 65 to pivot under the action of the spring device 67, thereby moving the side bars 48 and 49 in the carriages 68, as described above.

Attached to the shaft of the drive wheel 62a is a second gear or pulley around which an "endless" chain 74 (Figs. 9 and 7) runs, which drives shafts suitably connected to a pinch roller 46 and a large gear 75 · Chain 76 (Fig. 7), which is powered by dental. of the wheel 75 »in turn uses a gear 77» which in turn is connected to a chain which drives a small gear 78. The gears 77 and 78 again drive rollers 26, and the chain 76 drives fingers 27 which move the sheet forward through the machine. The second shaft of the gear 75 has a guide cam 79. Against it moves a push cam 80 fixed to the lever 81, which in turn articulates at 82. The free end of the lever 81 is fixed by a cable 83 to the wheel 85 as the cable passes around the wheel 84 and partially rotates the wheel 85 back and forth. The wire 86 wound around the wheel 85 rotates around the wheels 87 and 88 8 61662 (the wheels again rotate in opposite directions to each other). The cable is attached at both ends to tension springs 89 connected to the frame 11. The wheels 87 and 88 are mounted on shafts 12, and when the guide cam 79 rotates the lever 81 during each rotation, turning the cable 83 backwards rotates the wheel 85 * and then the wheels 87 and 88 (rotate in opposite directions). pivots the plates 13 and at the same time the suction cups 16 and the retaining rod 21, as already described above. The fingers 89 on the shaft 61 remove the tubular can from the apparatus. The different gear ratios as well as the shapes and the settings of the cams are chosen so that the next work steps of the sheet take place correctly in synchronization, whereby a continuous can flow flows through the device.

From the above description, it can be seen that the invention provides an apparatus capable of partially raising a series of flat sheet sheets and thereby forming carefully sealed and rectangular tubular can bodies which can be subsequently fed to a packaging machine for packaging and final sealing. , the invention is not limited exclusively to details and parts as described above, but may be modified in different ways in order to be able to meet the various requirements for equipment, without departing from the scope of the invention as defined in the appended claims.
