Abstract

A machine for the processing of packing containers of the type used for example for milk products. Such packing containers are manufactured from a filled material tube and are first given cushion-shape. With the help of the machine in accordance with the invention they are subsequently converted to a substantially parallelepipedic shape. The machine comprises a means of transport in the form of a wheel (35) having radial holding devices (37) for the cushion-shaped semi-finished products (2). The means of transport can be rotated step-by-step so that each indiviual packing container passes around processing stations (45 - 50) placed around the periphery of the means of transport for the folding of corner lugs, sealing and shaping.

Packaging machine tool

The invention relates to a packaging machine machine comprising a conveying member in the form of a periodically rotatable drum 5 with guided, controllable posts for moving the packaging containers between different machining stations arranged around the conveying member, the fasteners being guided between an open and closed position.

In the manufacture of disposable packaging for liquid dairy products and the like, the starting material is a web of material which is flexible but relatively rigid in shape, comprising layers of paper, thermoplastic and possibly aluminum sheets. The web of material is fed in the form of a roll to a packaging machine, which gradually shapes the web of material into a hose or tube by attaching the longitudinal edges of the web to each other. The liquid-retaining tube is filled with filler, after which it is divided into separate, mainly cushion-shaped packaging containers by squeezing together and securing to each other evenly spaced areas transversely extending in the tube. The packaging containers thus obtained are formed in connection with said compression and fastening into mainly parallelepiped-shaped units, which are separated from each other by cuts in transverse sealing areas. However, the trapezoidal shape is disturbed both by said protruding closure-shaped closure areas and by four triangular, double-walled corner strips, which, for geometric reasons, are formed by excessively shaping the material from a cushion shape to a substantially parallelepiped shape.

Each individual packaging container is then passed on to a packaging container processing machine (for so-called final shaping or folding) which may be further integrated with the main packaging machine. both the closing fins and the corner strips are folded inwards towards the actual container body and joined thereto to obtain a packaging container 35 with a more correct parallelogram shape.

This machining or final folding of each individual packaging container manufactured by the packaging machine takes place gradually 2 71283, so that each packaging container is transferred between different processing stations in the final folding machine and is machined therein, whereby throughout the machining period they determine e.g. thermoplastic heat sealing times, which makes it difficult to design a final folding machine that operates fast enough to serve high-speed packaging machines.

The stepwise transfer of the more or less preformed packaging containers via the final folding machine also places great demands on accuracy if it is to be guaranteed 10 that each packaging container moves to just the right machining position at each position.

Previously used final folding machines are not able to process packaging containers with sufficient precision and reliability at the high working speeds that must be used in modern packaging machines, and therefore there is a general need for an final folding machine designed to be faster and more accurate.

It is therefore an object of the present invention to provide a machine for packaging containers which does not have the disadvantages of the prior art but which operates safely and quickly. It is a further object of the present invention to provide such a machine which reliably moves and controls the packaging containers between certain stations at each processing station. It is a further object of the present invention to provide a machine capable of performing the safe and accurate folding and shaping of both sealing and corner strips. It is a further object of the present invention to finally provide a final folding machine with a high overall power, although it makes it possible to extend the machining time in each different machining station.

These and other objects are achieved according to the invention by giving the type of machine mentioned in the introduction the feature that the members acting on the packaging containers are adapted to move the packaging container in the fastener radially with respect to the drum center 35 as part of the rotation of the conveying member.

In addition, the preferred embodiments of the machine according to the invention have been given the features which appear in the dependent claims.

With this design of the machine according to the invention, a packaging container processing or finishing machine has been developed which, in addition to allowing very high working speeds, also allows the working time available in each station to be extended, while ensuring partially processed packaging containers are moved between precisely defined positions at each processing station. The machine according to the invention also ensures the safe control of the packaging containers during transport between the machining stations and, finally, that the insertion of the corner strips takes place in stages in a well-defined and precise manner.

The preferred embodiment of the machine according to the invention will now be described in more detail, in particular with reference to the accompanying drawings, which schematically show the preferred embodiment of the machine according to the invention, with only the parts necessary for understanding the structure and operation of the machine shown in the figures.

Figure 1 schematically shows a preferred embodiment of a machine according to the invention. The machine is connected to a conventional packaging machine next to it and the figure shows only a limited part 1. The machine 10 according to the invention is designed to receive and process pre-delivered packaging containers 2 from the packaging machine 1 and is therefore driven synchronously with the packaging machine 1 by a drive shaft 3 connecting the machine to the packaging machine. with butter manoton 4.

For the sake of clarity, the machine according to the invention can be divided into three main parts, namely the actual final folding part 5, where the obtained packaging containers are gradually processed, the transport part 6, which transfers the packaging containers 2 from the packaging machine 1 to the final folding part 5 and the transmission 20 and drive part 7, which uses final folding. part 5 and transport part 6 in synchronism with the packaging machine 1. The transmission part and the drive part 7 are located at the bottom of the machine and at the same time form a platform for the other parts. The transport part 6 is between the packaging machine 1 and the final folding part 5, where under the transport part 6 there is a space for a conveyor 8 mounted on the drive part 7, extending at right angles to the transport part 6 and designed to remove pre-formed packaging containers 2 from the final folding part 5 for further transport to a packer. assembles several different 30 packaging containers into 2 larger collection packages that facilitate transport to the consumer.

The conveying part 6 comprises a base 9 with two parallel, elongated side walls, between which the packaging containers are conveyed from the packaging machine 1 to the final folding part 35 5 by an endless main conveyor belt 10 running around pivot rollers arranged at both ends of the conveying part 6. 71283 between parallel pages. The turntable 11 is connected to a drive motor (not shown) and at the same time acts as a turntable of a second conveyor belt 12, which belt is formed as a receiving conveyor belt for packaging containers coming from the packaging machine 1. Both the receiving conveyor belt 12 and the main conveyor belt 10 include a plurality of parallel belts spaced apart so that they can pass around the common reversing roller 11 without interfering interconnection.

The main conveyor belt 10 extends substantially horizontally slightly upwards towards the final folding part 5, while the wadding-taking conveyor belt 12 tilts slightly in the opposite direction and, as described in more detail, extends upwards towards the packaging machine 1 at an angle of about 30 °. Thus, after a short free fall distance, the partially shaped packaging containers delivered from the packaging machine 15 come to the inclined conveyor belt 12, which brakes them, after which they are transferred directly to the main conveyor belt 10 for further delivery to the final folding section 5. Towards the final folding section 20 5 above it is an outlet conveyor belt 13 which runs in the same main direction as the main conveyor belt 10, but is above it at a distance which roughly corresponds to or slightly exceeds the height of the packaging containers 25 conveyed by the main conveyor belt 10. The main conveyor belt 10 and the receiving conveyor belt 12 are operated at a constant constant speed, but the output conveyor belt 13 is operated at a constant speed which is twice the speed of the main conveyor belt 10. By means of the handle 14 projecting from the conveyor belt 13, the feed of the packages received by the main conveyor belt 10 is transferred to the outlet conveyor belt 13, which transfers the packages at twice the last speed from the main conveyor belt 10 and further to the final folding section 5. Thus, the packages successively transferred to the final folding section 5 - The distance between the 35 containers is larger than the distance between the packaging containers fed along the main conveyor belt 10, which is important for the operation of the final folding part, which will be described in more detail below.

6 71283

The transmission or drive part 7 below the transport part 6 extends from the lower end of the packaging machine 1 and inside under the actual final folding part 5. The transmission part 7 includes an open part shown on the left in Fig. 1, in which the drive shaft 5 extends and connects the powertrain 4 to a closed transfer case 15 shown on the right in Fig. 1, which at the same time forms a base for the final folding part 5. parallel lever and bottom and has three main functions, namely en-10 therefore it prevents contact with the drive shaft 3, secondly it determines the correct distance from the packing machine 1 to the final folding part and thirdly it serves as an assembly base for liquid, e.g. filling from leaking packaging containers. The drive shaft 3 connects the drive machine drive motor to the drive system 5 of the packing machine via suitable switches and gearboxes 15 (not shown) so that the end folding section can be automatically operated in synchronism with the packing machine. It is also possible to operate the final folding part 5 with a separate, not shown drive motor, which 20 e.g. enables continuous operation with the final folding part 5 and the transport part 6 when the main packaging machine 1 is stopped.

The actual main part of the machine according to the invention, i.e. the final folding part 5, has a base which at the bottom contains the above-mentioned transfer gear 15. On top of this there is a second gearbox 25 which includes a setting gear 16, and on top there is also a gearbox containing an upper bevel gear. the drive shaft 3 extending through the part 7 is connected by a switch to the input shaft 18 of the transfer case 15 (Fig. 3). The input shaft 18 extends horizontally in the split gear 30 and uses the lower bevel 19 and the rear bevel 20. The rear bevel 20 also transmits the rotation of the input shaft 18 horizontally but at an angle to the lower shaft 22 at the two ends of the guide shaft. through the movement as a reciprocating oscillating movement for two mounted control arms 23 pivoting to the transfer case, the operation of which is described in more detail below.

7 71283

The rotational movement of the input shaft 18 is further transmitted via the aforementioned lower bevel gear 19 to a camshaft 24 extending vertically through the final folding section 5, which drives the setting gear 16, 5 through the bevel gear so as to convert the camshaft 24 into a setting shaft / 6 rounds. Through the second output of the setting gear, the rotational movement is further transmitted via the upper bevel gear 17 to the horizontal shaft 10 directly located on the upper shaft 26, which has cam curves 27 at both ends, the operation of which will be described in more detail below.

Finally, the input shaft 18 also carries a feed cam plate 28 which, via a cam follower 29, drives a feed device 30 pivotally mounted outside the transfer gear 15 and includes two substantially vertical arms 31 extending on either side of the drive shaft. The arms 31 rest on two parallel shafts 32 both rotatably mounted to the end 15 of the transfer case. However, the second shaft 32 extends 20 at one end into the transfer case, where it carries the cam follower. Through this axis, the feeder 30 can be operated with a reciprocating movement. At their upper part, the two pivoting arms 31 carry the inlet means 33 and the outlet means 34, which are suspended in a parallelepiped on the arms 31. The operation of the two feed means 33, 34 is described below. The manifold 15 is shaped as an oil base and partially filled with oil, which is fed by pumps (not shown) to various moving parts in the final folding section, such as shafts, bevel gears, etc., to avoid oil leaks and contamination of the packaging containers treated in the final folding section 5. the operating system described is completely closed.

The machine will now be described in more detail with particular reference to Fig. 2, which shows the final folding part 5 itself in perspective. The figure shows how the base described above, formed by the transfer case 15, the setting gear 16 and the upper bevel gear e 71283 17, carries two rotatable conveying members 35. Each conveying member 35 includes a central rotatable drum 36 rigidly connected to the intermediate shaft adjusting gear 16 on. The two conveying members 35 are identical (and therefore only the other is continuously described) and are located axially on the same line on both sides of the setting gear 16. The conveying means 35 is used to move the packaging containers delivered via the conveying part 6 (Fig. 1) between the different processing stations 10 of the final folding part, and the conveying member therefore has fasteners 37 evenly spaced along the drum 36, each containing a fixed and movable column 38 and 39, respectively. 4), which between the substantially flat work surfaces facing each other form a space adapted to the size of the packaging container 2. Each fixed post 38 is substantially L-shaped, with the longer branch of the L-shape forming said working surface extending substantially radially with respect to the drum 36, while the shorter branch extending at an angle of 90 ° to the working surface so that said shorter branch 20 forms the base 40 of the fastener 37. .The bottom has a recess in which the closing opening of the packaging containers is located. The shorter leg of the fixed column 38 is rigidly connected to the drum 36. The movable column 39 is pivotally mounted parallel to the central axis 41 of the drum about an extending axis 41.

More specifically, the pivotally mounted post 39 forms a second arm on the lever 42, the second arm of which carries a cam follower 43 in continuous engagement with a fixedly mounted double cam curve 44 in the center of the drum 36. As the conveying member 35 rotates, the cam curve 30 acts on the column moving through the cam follower 43 and the lever 42 so that it moves to a closed position where the planar working surface of the column 39 extends parallel to the working surface of the fixed column 38 (longer leg), and the open between a position in which the movable post 39 is pivoted out at an angle of about 10 ° 35 with respect to the fixed post 38, which will be described in more detail in the following description of the operation of the machine.

A plurality of machining stations are distributed around the conveying member 35 with a mutual division corresponding to the division between the fasteners 37 of the conveying member. As best seen in Figure 1, at the end of the conveying section 6 there is a feed station 5, followed by a pre-folding station 46 closest to the central axis of the conveying member 35 and followed by a binder station 47, a final folding station 48, an unused spare station 49 and an exit station 50. The various stations are then mentioned in the order in which they are reached by the individual packaging container moved by means of the transport element 35 during the use of the machine 10. Thus, in use, the conveying member 35 is set stepwise in a clockwise direction in Fig. 1, whereby each movement corresponds to a rotation which corresponds to the division angle (60 °) between the different positions.

Each conveying member 35 is surrounded not only by various machining stations but also by a plurality of guide rails (Fig. 4) fixedly mounted relative to the machine base and designed to guide and machine the packaging containers moved by the conveying member. Each conveyor member 35 cooperates with two different types of guide rails, namely on the other hand outer guide rails 51 extending around the conveyor member at substantially the same level as the top ends of the fasteners 37 and inner guide rails 52 extending around the conveyor member mainly at the base surfaces 40 of the fasteners 37. Both the outer and inner guide rails are double and located on both sides of the conveyor member 35, as best seen in Figure 2. The guide rails 51, 52 are fixedly connected to the sides of the stand 53 outside the conveyor member 35, which stand is rigidly connected to the machine base. Figure 2 shows the stand 53 with dotted lines only for clarity. The guide rails 51, 52 are thus fixed and thus do not follow the conveying member 35 during this setting movement.

The two outer guide rails 51 start at the level of the inlet-35 workstation and extend mainly from here to the pre-folding station and further around the conveying member ending at the outlet station. The distance between the two guide rails 51 and the central axis of the conveying member 35 varies in that the guide rails 51 at the level of the input station 45 are closer to the central axis of the conveying member than on their remaining journey around the conveying member. More specifically, the distance between the guide rails 51 and the central axis of the conveyor member gradually increases with the distance between the insertion station and the pre-folding station, after which it decreases again so that the guide rails approach the periphery of the conveyor member and extend at substantially the same distance. Then, on said first distance of the guide rails, the distance between the guide rails 51 and the bottom surfaces 40 of the fasteners 37 gradually increases in the direction of movement of the fastener 37 from a distance less than the height of the fastener 37 to a distance greater than the height of the fastener 37. The guide rails 51 then approach the height of the fastener again, then further extending at this height to the exit station. The distance between the two guide rails also varies. In the first 20 parts of the guide rails, i.e. between the insertion station and the pre-folding station, the distance between the guide rails 51 is slightly larger than the width of the fastener 37, i.e. the distance between the side surfaces of the posts 38, 39 measured parallel to the central axis of the conveying member 35. On the way from the insertion station to the pre-folding station, this distance 25 gradually decreases, while the guide rails 51, as described above, increasingly move away from the central axis of the conveyor 35 and the distance between the guide rails 51 at the pre-folding position 46 decreases so that the distance between the guide rails 51 between the side surfaces of the posts 38, 39. At the end of the guide rails 51 around the conveying member 35, the distance is further gradually reduced so that it is slightly smaller at the level of the binder station 47 than the distance between the side surfaces of the posts 38, 39. This distance py-35 causes substantially the same distance from the guide rails 51 to the out-feed station.

il 71283

Both inner guide rails 52, like the outer guide rails 51, extend around the conveying member 35 upstream of or between the feed station 45 and the end of the feed station 50 and downstream of the feed station 50. However, the two inner guide rails 52 are located much closer to the central axis of the transport member 35, so that they are substantially level with the bottom surfaces 40 of the fastener 37. The guide rails 52 extend their entire length at a distance outside the side surfaces of the two posts 38, 39, i.e. the distance between the facing surfaces of the guide rails 52 is slightly greater than the width of the posts 38, 39. The width of the posts 38, 39 as used herein, as well as in other parts of the description and claims, means the distance between the spaced apart side surfaces of each post, which distance substantially corresponds to the width of the treated packaging container. The height of the fastener again means the distance from the bottom surface of the fastener towards the fastener to the outer end of the posts 38, 39. The height of the fastener 37 corresponds substantially to the height of the treated packaging container.

The initial ends of the two guide rails are at the insertion station at a distance from the central axis of the conveying member 35, which distance is slightly below the distance between the bottom surface 40 of the fastener and said central axis, i. the guide rails 52 25 are slightly "below" the bottom surface 40 of the fastener. From the feed station 45, the distance between the center axis of the two guide rails 52 and the conveying member 35 then gradually increases, so that the guide rails are at a slightly greater distance from said center axis than the bottom surface 40 of the fastener 37 at the level of the pre-folding station 46. Both guide rails 52 then extend beyond the base surface 40 " to the downstream end.

Both the outer guide rails 51 and the inner guide rails 52 are preferably metal tubes through which a cooling medium, e.g. water, can be circulated during operation of the machine.

12 71 283

As mentioned above, there are a number of permanently mounted machining stations around the conveying member 35, between which the packaging containers are designed to be moved periodically during machining and shaping by means of the fasteners of the conveying member. During the rotation of the transport member 35, the movable posts 39 of the fasteners are moved between the open and closed positions by means of a coupling between the cam followers 43 and the cam curve 44. In the open position, the movable column is in a slightly unfolded position relative to the fixed column, which enables the transfer of the packaging container in question. to or from the bracket. In the closed position, the working surfaces of the two pillars are substantially parallel and have such a mutual distance that they easily hold between them the packaging container placed in the fastener 15 even when the fastener is upside down, i.e. at each lower part of the transport member 35. To allow said control of the movable posts 39, the radius of the cam curve 44 varies along its circumference. More specifically, the cam curve radius is substantially in the side 20 rpm relatively small, and then increases to a maximum and then gradually decreases again mentioned earlier, the low beam. The part of the cam curve in which the radius gradually decreases from said maximum radius to the area of the smaller radius is located so that the fastener-25 met 37 are in the intermediate position, i. are partially open when in the pre-folding position 46. "Partially open" means that the fastener, while holding the packaging container between the posts, still allows a certain movement or repair of the packaging container position in the fastener if external forces are applied to the packaging container 30. In addition, the various parts of the cam curve are positioned so that the fasteners are open during the intermittent rotation of the conveying member when in the inlet and outlet stations and closed when in the binder and compression stations. In the partially open position 35, where the fasteners 37 are in the pre-folding position 46, the packing container in the fastener is surrounded by both posts 38, 39, but these do not hold the packing container i3 71 283 fixedly, but can be moved by external forces with a certain resistance.

The feed station 45 is located at the level of the feeder 33, which rests on the feeder 30 and thereby 5 can be reciprocated between the feed stations of the two conveyors 35, allowing the packaging containers from the conveyor 6 to move along a trough (not shown) extending transversely between the conveyors 35. The insertion station also has a stop 54 positioned on the side of the stand 53, which is a plate directly in front of the inserter 33, which limits the movement of the packaging containers and ensures that they are in the correct position in the open fastener. The stroke length of the feeder 33 is such that the distance between the feeder and said stop 54 in the pivot position of the feeder corresponds to the width of the packaging container, which ensures the correct positioning of the packaging container and its attachment between the fastener posts.

The pre-folding station 46 includes a bottom folding plate 55 located above the bracket therein and two top-end folding plates 56 located on either side of the fastener (Figure 9). Both the bottom folding plate 55 and the top end folding plates 56 rest on a support arm 57 which is freely pivotally mounted on a transverse support shaft 58 extending parallel to the central axis of the conveying member 35.

The bottom fold plate 55 and the top end fold plates 56 are synchronously displaceable between the upper position and the lower position by a cam curve 27 mounted on the upper shaft 26 which contacts and acts on a roller 59 rotatably mounted on the bottom fold plate 55 which can be pressed by the spring curve 27 . The base folding plate 55 has a flat working surface facing the fastener, which in the upper rest position of the base folding plate is spaced from the outer end (upper) of the fastener above it so that it is under the action of the cam curve 27 in its working position 35 substantially at the outer edge of the fastener 37, i.e. at the level of the surfaces of the upper ends of the two pillars 38, 39. The base folding plate 55 is i.e. movable in the radial direction of the conveying member from its rest position 71283 14 to its operating position outside the two guide rails 51 between the guide rails and the center of the conveying member. The bottom folding plate 55 is then 2-10 mm narrower than the free space between the guide rails 51 at the level of the pre-folding station. This 5 dimension is adapted to the material thickness of the machined packaging container. The reciprocating movement of the base folding plate 55 provided by the cam curve 27 further gives a corresponding movement to the two upper end folding plates 56 on both sides of the fastener, since these are connected to the support arm 57 by the intermediate arms 60. The lower, i.e. the outer edges towards the central axis of the conveying member 35 are thus moved between a rest position at a distance above the bottom surface 40 of the fastener 37 and a working position substantially at the level of said bottom surface. In this case, the top-fold folding plates 56 are designed to co-operate with two abutment inner guide rails 52 in the pre-folding position on both sides of the fastener and at a distance from the base surface 40 above it. Between the insertion station 45 and the pre-folding station 46 is a guide plate 61 suspended from the support arm 57 and intended to follow this oscillating movement as the cam curve 27 moves the base folding plate 55 between its upper and lower positions. The guide plate 61 is located slightly outside the outer ends of the fastener 37 and its width substantially corresponds to the width of the bottom folding plate 55.

In the illustrated embodiment of the machine of the invention, the binder station 47 is provided with a slack air device 62 fixedly mounted outside the trajectory of the conveying member 35. The hot air device 62 is of a known type and emits warm air which is supplied through pipes and nozzles to the packaging containers placed by the transport member in the binder station. More specifically, warm air is supplied through two bottom nozzles 63 spaced beyond the outer interface 35 of the fastener 37 to extend under the partially unfolded bottom strips of the package container attached to the fastener and through an upper nozzle 64 on either side of the inner end of the two fasteners. between the side wall of the packaging container and the partially folded top strips of the packaging container. Both the bottom nozzles 63 and the upper nozzles 64 are on the side of the trajectory ul-5 of the conveying member 35, so that they do not interfere with the rotation of the conveying member.

In another embodiment of the machine according to the invention, the hot air device 62 and the hot air nozzles 63, 64 can be replaced by a so-called with a hot-melt device, i.e. with a device that feeds a thermoplastic binder to the packaging container. The arrangement of the hot-melt nozzles then corresponds substantially to the arrangement of the nozzles 63, 64, since the hot-melt must be placed in the same way as the hot air between the corner strips of the packaging container and the wall of the packaging container against which the corner strips must later be folded down. Such hot-melt devices are well known and will not be described in more detail.

The final folding station 48 includes a final folding device 65 (Figures 5, 6) shaped for such final folding or final shaping of the packaging containers so that they obtain the desired parallelogram shape with the folded and fixed corner strips. The final folding device therefore includes two side presses 66 and one bottom presser 67 designed in their working position together with the two posts 38, 39 of the fastener and the bottom 40 of the fastener to form a substantially closed, parallelepiped space having internal dimensions corresponding to the desired final dimensions of the packaging container. Both side presses 66 include pressure plates 68 having facing work surfaces that are completely flat except for the inner guide rails 52 of the grooves 69. Each pressure plate 68 rests on a front lever arm 70 by means of which the pressure plate is pivotally connected to the connecting member 71. The connecting members 71 include rubber sleeves and are flexible so that the pressure plate 68 tends to assume a position substantially parallel to the lever 70. However, each of the pressure plates 68 may, in contact with the flexibility of the connecting member 71 with the side wall of the packaging container, engage in uniform contact therewith.

71 283 16

Each front lever arm 70 is connected to a rear lever arm 73 within the transfer case 15 via a shaft 72 mounted on the machine base. The rear lever arms 73 are formed by loops and a knee joint structure 74, connected via a conventional system to a handlebar 75 which carries a bottom presser 67 at its front end. The bottom presser 67, which, like the side presses 66, has a flat work surface 66 for the side synchronized 10 with the packing container from the guide arms 23 in the transfer gear 15 by means of a second arm which is driven by the lower shaft 21 of the machine via guide curves 22.

In order to prevent damage to the final folding device 65 or the transport member 35 if, for example, foreign objects 15 prevent movement, a safety switch 76 is built into the operating system between the control arm 23 and the actual final folding device 65. The safety switch 76 is of the known type which trips itself under a certain load and does not need to be described in more detail. Both the safety switch 76 and the other part 20 of the drive mechanism for the final folding device 65 are, as shown in particular in Fig. 5, housed in a bearing housing 77 mounted on a transfer gear 15. Thus outside the bearing housing there are only two side clamps 66 and a bottom clamp 67. that is, between a rest position in which both the side presses and the bottom press are so spaced from the conveying member 35 that the fastener 37 can pass freely therebetween and a working position in which the side presses and the bottom press are pressed into the packing container in the end position. against.

The next processing station of the packaging container moved by the conveying member 35 is a spare station 49 which can be used for the desired further processing of the packaging container, e.g. for attaching reinforcing strips, date stamping and the like.

The output station 50 is directly in front of the output feeder 34, which is designed to be moved in synchronism with the feeder 33 17 71 283 by means of the arms 31 of the reciprocating feeder. The outlet feeder 34, like the inlet feeder 33, includes pressure plates 78 designed to move from a package container holder 37, the movable column 5 and 39 of which in the outlet position have been moved to its unfolded position by a cam curve 44. During the rotation of the feeder 30, the pressure plate 78 moves the packaging container one by one from the fastener 37 to an adjacent (outside) non-shown slide designed to transfer the package 10 to said conveyor 8, on which the packaging containers are moved vertically away from the machine according to the invention.

When the machine according to the invention is used in conjunction with a packaging machine for shaping substantially parallelepiped-shaped container containers for liquid filling packaging containers, the machine is positioned according to Fig. 1, i. next to the packaging machine and connected to it by transmissions via the drive part 7. When the actual packaging machine is started, the machine according to the invention is also started, because it is operated by means of a drive of the packaging machine. Packaging containers or blanks from the actual packaging machine, which are completely filled and closed, leave the packaging machine when they are separated from the tube from which they are made and are allowed to fall down on the receiving conveyor belt 12, 25 which, because it is at an angle to the horizontal, the packaging containers softly and transfer them to the main conveyor belt 10, on which they are fed at small intervals towards the final folding section 5. As the packaging container approaches the main conveyor belt 10, on which they are fed at the smallest central 30 intervals towards the final folding section 5. As the packaging container approaches the main conveyor belt 10 end, the feed moves forward to the outlet conveyor belt 13, which is operated at substantially twice the speed of the main conveyor belt 10. The handles 14 35 of the outlet conveyor belt 13 engage a single packaging container and transfer it from the end of the main conveyor belt 10 to a transverse feeder 18 71 283 stores. The output conveyor belt 13 is then synchronized with the movement of the feeder 33 so that it is always in one of its pivoting positions when the packaging container is fed into the trough. When the feeder 33 moves to its opposite limit position 5, the fed packaging container is pushed through a trough into one of the fasteners 37 of the transport members 35 in the feeding station, where the stop 54 stops the packaging container in the correct position.

The fastener 37 is dimensioned so that the bottom surface of the packaging container 2 placed therein rests against the bottom 40 of the fastener, while its protruding top and bottom corner strips 79 and 80, respectively (the container is turned upside down in Figure 7) rest against the two inner guide rails 52 and the other outer rail. against the guide rail 51. In the open position, the column 39 is at a small distance from the side wall of the packaging container and the guide plate 61 is at a distance from the protruding closing opening 81 of the packaging container. Just before the conveying member 35 is inserted again, the end of the guide damper 61 shown in Fig. 7 is lowered towards the closing plate 81. At the same time, the 55 is returned to its rest position in the pre-folding position.

As the guide plate 61 is moved towards the closure 81, the conveying member 35 is positioned (clockwise in Fig. 2) so that the packaging container 2 slides along the guide rails 51, 52 from the feed station towards the pre-folding station 46. Fig. 8 shows the packaging container and the fastener in the two positions. between stations, i.e. as the packaging container moves to the right in the figure. Because the guide plate 61 contacts the closure flap 81, it has folded it down toward the bottom surface 82 of the packaging container 30. As mentioned above, the packaging container will not be fixed to the fastener until it has passed the pre-folding position and the movable post 39 in the position shown in Figure 8 is still spaced sideways. so that the packaging container 35 can be moved freely in the fastener and guided by the guide rails 51, 52. As their radius gradually increases in the area between the insertion station and the pre-folding station i9 71 2 8 3, the packaging container is raised due to the connection between the protruding corner strips and the guide rails so as to be spaced from the bottom 40 of the fastener 37. At the same time, the closing flaps 81 are folded backwards. in the direction of movement as they contact the guide plate 61 and the two inner guide rails 52.

When the positioning movement of the transport member 35 ceases, the packaging container is located in the pre-folding station 46. In this position, the movable post 39 has partially contacted the side of the packaging container 2, but the packaging container is not completely closed but can still be moved in the holder 37 (Fig. 9). Due to the contact between the guide rails and the corner strips of the packaging container, the packaging container is in an outer or upper position in which its bottom surface 82 is immediately below the working surface of the packaging container towards the bottom in the rest position. The setting gear 17 now causes the upper shaft 26 to rotate, whereby the cam curves 27 move both the bottom folding plate 55 and the upper end folding plates 56 towards the central axis of the transport member 35 and back. This movement moves the packaging container downwards until its bottom surface rests on the base 40 of the fastener 37 and the packaging container is again in the position in which it was placed in the fastener during insertion. Since the guide rails 51, 52 are in the pre-folding position 25 at a greater distance from the central axis of the conveying member 35 than they were in the feed station 45, the corner strips 79, 80 of the packaging container are folded upwards during this movement, i. away from the central axis of the transport member. The top strips 79 at the bottom surface 40 of the fastener 30 are folded around the outer ends of the top end folding plates 56 so that they are at an angle of about 45 ° to the side surface of the packaging container. The two bottom corner strips 80 are folded more and, after the movement performed, extend substantially straight upwards, i.e. At a 90 ° angle to the bottom surface 82 of the packaging container. Folding of the two bottom corner strips 80 must occur while compressing layers of material in the corner strips, as these must later be folded down toward the bottom surface 82 of the packaging container and secured against it over which the closure 81 extends. Since a large number of layers of material must be folded and compressed before the corner strips 5 are properly attached to the base surface 82, this pre-folding of the corner strips must compress them, and in particular the overlapping portions 81 between the sides of the base folding plate 55 and the two outer guide rails 51. This can be done by ensuring that the free distance on both sides of the base pressure plate is as small as possible in relation to the thickness of the material and is preferably at a value compatible with the theoretical material thickness of the corner strips (usually 1-5 mm). When both the bottom folding plate 55 and the top folding plates 56 have returned to their outer rest position, the transport member 35 is again set (1/6 turn clockwise), which takes the packaging container from the pre-folding position to the binder station 47. During this transfer, the fastener 37 becomes closed as the movable column 39 moves to a position in which it is parallel to the post 38 of the fastener, so that the packaging container remains immovably attached to the fastener. Since the distance between the two outer guide rails 51 decreases slightly in the area between the pre-folding station and the binder station, the two base strips 80 are still folded somewhat towards each other so that they are at an angle of about 45 ° to the base surface 82 when the packaging container enters the binder station 47.

When the fastener 37 stops at the binder position, the packaging container 2 is in such a position that the bottom nozzles 63 of the hot air device are in a space between the partially folded bottom corner strips 80 and the bottom surface 82 of the packaging container (Fig. 10). At the same time, the upper nozzles 64 of the hot air device 62 are located on both sides of the upper end of the packaging container towards the bottom 40 of the fastener and more closely defined between the free side surfaces of the partially folded top corner strips 79 and 35 of the packaging container. By means of outflow holes directed towards the nozzles 63, 64 towards both the corner strips and the packaging container walls, 21 71283 warm air is now blown towards the surface of the packaging container material in the areas below the corner belts to be used to attach the corner strips to the wall of the packaging container below. Thus, the thermoplastic layer of the packaging container becomes heated to such an extent that it softens and can act as a binder in the attachment of the corner strips. After the thermoplastic material is heated to the softening temperature, the packaging container is moved by the conveying member 35 until it is in the final folding position 48. During this transfer, the center position of the guide rails 51, 52 further changes slightly so that as the packaging container enters the final folding position, the angle strips are at an angle slightly below 45. This prevents the heated surfaces from cooling unnecessarily when the packaging container is moved to the final folding position.

15 When the packaging container is moved to the final folding station 48, the side clamps 66 and bottom clamps 67 of the final folding device 65 are spaced from the fastener path so that they do not interfere with the protruding corner tabs 79, 80 of the packaging container. the bottom press gradually contacts the side walls of the packaging container and the bottom, respectively. As long as they are not affected by external forces, the pressure plates 68 of the side presses 66 are oriented relative to the lever arms 70 so that they first contact the side walls of the packaging container at their ends facing the bottom of the packaging container, then gradually turn the joint 71 as the levers continue to rotate. , until they 30 are parallel to each other and contact the free side walls of the packaging container. Since the pressure plates 68 are in the "oblique position" at rest, the stroke length of the levers can be kept small, as the ends at the top plates of the pressure plates get a relatively larger distance from the packaging container at rest so that the corner strips 79 can fit without difficulty. The relative positions of the two pressure plates 68 and the bottom presser 67 are shown in Fig. 11, 71283 22 where the dotted lines show the position of the pressure plates 68 at the time they first touch the side surface of the packaging container. Due to this flexible suspension of the pressure plates 68, they automatically position themselves in the correct position relative to the side surfaces of the packaging container, so that the risk of damage or deformation of the packaging container is considerably reduced. When both the side presses and the bottom press have been brought into the correct position, they, together with the fasteners and the base, form a substantially closed, parallelepiped-shaped space, the free internal dimensions of which correspond to the desired dimensions of the finished packaging container. The packaging container must remain in this position until the thermoplastic layer has hardened again and sealing has been completed.

The packaging container is then transferred by rotating the conveying member 35 again by 1/6 turn to a spare station 49 not used in this embodiment, where e.g. reinforcing cardboard sheets can be attached to one or more free surfaces of the packaging container (Fig. 12). When the transport member 35 is rotated again, the fastener 37 is obtained. pak-20 with the bowl tank to the outlet station 50. When rotated from the reserve station 49, the cam follower 43 of the movable column 39 gradually extends out to the part of the cam curve where the radius is greatest, i. where the fastener is opened. The packaging container is still held in place in the holder, in particular by means of two outer guide rails 51, against which the bottom of the packaging container slides when it is moved to the dispensing station.

At the outlet station (Fig. 13), the pressure plates 78 of the reciprocating outlet 34 are transferred inside the two posts 38, 39 of the fastener, whereby the detached packaging container 30 is pushed laterally out of the fastener 37 onto a non-shown sliding surface 8 outside the conveyor 35. The preformed packaging containers are thus fed out alternately from the two conveying members 35 of the final folding part 5 and transferred to the conveyor for removal.

As mentioned above, an alternative embodiment of the machine of the invention may be provided with a binder attachment device instead of the warm air device 62 shown in the figure. This modification can be used even if the machine 5 of the invention is used for the final shaping of packaging containers made of a material which is not covered with an outer layer of thermoplastic. The corner strips are then attached to the side walls of the packaging container with a thermoplastic adhesive, which is placed under the corner strips before they are pressed against the walls of the packaging container.

Equipping the machine according to the invention with a rotating conveyor which moves the packaging containers between different machining stations by means of a positioning movement ensures a safe movement of the packaging containers in precisely defined positions at each machining station, completely eliminating the risk of deformation of the packaging containers due to misalignment. In addition, since the all-moving, moving parts of the machine, i.e. the conveying member, the various machining stations, the feeder, etc., are operated from a common power source and are mechanically connected to each other by means of an operating arrangement, the synchronization between the different movements cannot be lost during normal operation. Therefore, the machine can also operate at high speeds without the risk of incorrect machining, which ensures a high production-25 power, which is further increased by the use of double conveying means which alternately process the incoming packaging containers.

Material banan is used in the form of an envelope in the form of a package 55 which is successful in the form of a material banan or slope of the genome of the banana field of origin. For the purposes of the present invention, the genomic expression of the packing material, including the material of the present invention, may be used. In addition, the form of the packing set is similar to that of the same compression and hopper coupling of the ameliorated parallelepiped enhancer, which is separated from the genome by a transverse formulation of 25 to 25 parts.

15 A third-party machine can be used as a means of transport to a large number of air conditioners, which can be used as a means of working in a modern manner.

20 These devices are designed for use in the manufacture of packaging materials, for example, for use in the construction of vehicles of the same type and in the same way. In order to achieve this, up to a maximum of 25 months of operation, a single fence and a strainer can be used as a fixed means of shielding. In order to achieve this, it is possible to use the same method as the mask and stand for the genome and the shape and shape of the formulation for a period of 30 hours. In order to achieve this, the upstream funding is limited to the number of employees and the number of employees and the total number of employees in the total capacity.

For example, the transport organization 35 finns et antal be-10 arbitningsstationer, vilka är anordnade med enbördes deliming the weight of the transport organization fästdon 37. Sámom framgär tydligast av figur 1 finns vid slutänden av trans-portdelen 6 en inmatningsstation 45, förvik-ningsstation 46, som är belägen huvudsakligen ovanför trans-15 portorganets 35 centrumaxel. After the stationary station 46 is connected to the binding station 47, the stationary station 48, and to the emergency station 49, as well as to the recovery station 50. However, the stationary harness has been angetted and denied under the drift of the masked vehicle, 20 35 förflyttad förpackningsbehällare.

The transport body 35 is indexed under the drift of the medium in Figure 1, the color being shielded from the upper end of the vehicle with a reference to the oil station (60 °).

25 For example, a vehicle assembly station is provided with a transport body 35 of which is provided by a ledge (Fig. 4), which is fastened to a masonry foundation and an anchor body and bearings of the transport body. Varje transportorgan 35 monverkar med 30 tvä olika typer av ledskenor, nämligen dels yttre ledskenor 51, som sträcker sig runt transportorganet huvudsakligen i jämnhöjd med fästdonets 37 yttre ändar, samt inre ledskenor 52, vilka sträcker sig runt transportunt Säväl de yttre som de inre led-35 skenorna är dubbla oc belägna pä ömse sidor av transportorganet 35, vilket tydligast framgär av figur 2. Ledskenorna 51, 52 är fast förbundna med utanför transportorganet 35 belägna sidor 71283 33 av ett stativ 53 som. This is the case with a fundamentals. Figure 53 illustrates a first step according to the first line of Figure 1. Figure 51, 52 is shown as having a single point of contact with the transport means.

In this case, the light source 51 is connected to the power supply station and the power supply unit is used as a means of transport to and from the transport station. The distance between the LED-10 screen 51 and the transport organ 35 of the central axis is varied from the signal channel 51 to the power station 45 at the end of the core transport organization. Närmare bestämt ekas avaständet mellan ledskenorna 51 och transportia orgets centrumaxel successful on sträckan mellan inmatningsstationen and förvikningsstationen at därefter at a number of countries. In accordance with Article 20 of the Treaty establishing the European Economic Community, the Community has set aside a total of EUR 37 for a period of 37 years. fästdonets 37 25 höjd. Ledskenorna 51 närmar sig därefter äter fästdonets höjd och löper därefter vidare pä denna höjd ända fram account utmatningsstationen. These measures may be taken in accordance with the provisions of this Regulation. Under this, for the purposes of the internal market, d.v.s. in addition to the inlet station and the inlet station, there are 20 outlets in which the ledge 51 faces the stern and the main body 37 bredd, d.v.s. avständet mellan backarnas 38, 39 sidoytor, mätt parallellt med transportorganets 35 centrumaxel.
