Definitions

  • the invention relates to methods and devices for automatically inserting box-shaped bags made of flexible packaging material into box-shaped large containers.
  • Such devices are very expensive due to their high throughput per unit time. Their use is also impossible for technical reasons when large box-shaped sacks made of flexible packaging material are inserted into large box-shaped containers.
  • Large box-shaped containers are understood to mean those which have a packaging volume of more than 100, preferably more than 200 1.
  • a preferred area of use for such large, box-shaped containers is, for example, for the storage and pressing of Thread cables given, as described in DE-OS 27 36 316.
  • the support container After the filled support container has been transported to a final press, the support container is pulled off and the cable material pre-pressed in the box-shaped sack is then subjected to a final compression in the form of a bale.
  • Large containers are also suitable for packaging cable tapes and fiber flakes, which must be lined with box-shaped bags made of flexible packaging material to protect the packed material against contamination on the container walls.
  • the method according to the invention is aimed at automatically inserting box-shaped sacks made of flexible packaging material into box-shaped large containers.
  • Corresponding clothing sets made of foils, jute fabrics or the like can be used as flexible packaging material.
  • plastic film which is laminated with a plastic film ribbon fabric, has proven itself, since such a material can be easily cut and sewn into box bags, glued or welded, but on the other hand has a much better tear resistance than usual foils.
  • Trolleys (2) are used for this purpose, which are provided with at least four clamping points (3,3 ', 4,4'). These clamping points must be so far apart in pairs that two opposite side surfaces of a sack can be clamped in at the upper edge, while the other two side surfaces and the bottom of the sack remain folded together.
  • FIG. 1 shows such trolleys (2) equipped with box bags (1). The trolleys (2) are on one first magazine track (5) stored and brought up to a stop (6) with the help of a not shown pushing device.
  • a pulling device (7) is then extended from the opposite side of the stop (6) and is equipped with at least two grippers (8, 8 ') which are approximately as far apart from one another as a side surface of the sack is wide.
  • the grippers (8,? ') Can be actuated, for example, via a small servo motor with a lever system or via a pneumatic drive (not shown).
  • the grippers (8,8 ') can be raised above the edge of the closest side surface of the box bag (1) and then lowered to the edge of the bag, this side surface being clamped resiliently into the grippers (8,8').
  • the pulling device (7) is moved back with the grippers (8,8 ').
  • the clamping connection of the clamping points (4, 4 ') of this side of the bag (1) is pulled out of the trolley (2) and the bag is shown as shown in FIGS. 1 to 3, at least spread out at its upper end.
  • FIG. 4 shows this insertion of the expanding device (9) in the folded state.
  • the spreading elements are expediently designed as a fourfold lever frame system which can be moved, for example, by a pneumatic drive system (11).
  • the spreading elements (10) are aligned along the four longitudinal edges of the box bag.
  • the sack edge is released from the clamping points (3,3 ') on the trolley (2) and from the resilient grippers (8,8') of the pulling device (7) by simply lowering the spreading device (9) further beyond the transfer point.
  • clamps (12) On the individual spreading elements (10) of the spreading device (9) there are clamps (12) which can be actuated in the vicinity of the edges of the bag and which are actuated by the spreading device at the latest after the stretched bag has been finally taken over.
  • the actuatable clamps (12) are arranged at such a height that they can hold the sack (1) stretched out on the expansion device (9) after tensioning and smoothing at its upper edge.
  • the spreading device (9) can be retracted or folded up.
  • the tensioned state of the sack after it has been removed from the clamping points (3,3 ') and the resilient grippers (8,8') of the pulling device (7) is shown in Fig. 5, while the state of the sack and the spreader are shown in Fig. 6 Folding in of the expansion device (9) can be seen. In this state, the spreading device can be moved into a box-shaped large container (14) with the aid of a movement device (13) and lowered there.
  • the pulling device (7) is out of the effective range of the Spreading frame (9) and thus removed from the vicinity of the stretched bag (1) by moving back with the help of a movement device, not shown.
  • the position of the box bag (1) in the large container (14) can be fixed in various ways.
  • the inner wall of the large container (14) can have absorbent or adhesive points that allow the position of the sack to be fixed in the large container (14). Preferred embodiments of fixing the position of the box bag (1) in the large container will be described below. If the position of the sack is ensured by one of these measures, the clamps (12) can be released, the spreading device (9) folded in and the entire spreading device can be moved out of the large container (14). The large container is then equipped on its inner surfaces with the box bag (1) of the appropriate size.
  • FIGS. 7 to 12 show preferred embodiments of the method according to the invention and the device required therefor.
  • the upper edge of the box sack is cut into a length (a) and the foldable strips that are formed on the upper edge of the box sack (1) are connected to holding devices (17) on the upper edge of the large container.
  • the box sack (1) is held at the upper ends of the longitudinal edges by two clamps (12 ', 1211) which are located near the sack edge.
  • a corresponding schematic representation in a supervision is shown in FIG.
  • An actuatable knife (18) acts between the two clamps (12 ', 12'') of each edge of the box bag and can be pivoted in and out by a movement device, not shown.
  • the expansion device (9) is usually folded in, the box bag (1) is then sunk into a large container with the help of the expansion device (9) and the expansion device (9 tensioned) in B e-container (14). After loosening the clamps (12) or (12 ', 12 "), foldable edges of the box sack (1) are now available, which can be connected to the upper edge of the large container (14) Fixing the position of the box bag in the large container (14) results, for example, by gluing, acting by suction heads, attaching or clamping.
  • FIG. 7 shows a preferred form of fixing the position of the box bag 1 in the large container (14).
  • FIG. 8 shows a preferred form of fixing the position of the box bag 1 in the large container (14).
  • the upper edges of the sack (1) which have become freely movable as a result of the action of the knives (18), are pushed into the resilient holding devices (17) of the large container (14) with the aid of a transfer device (19).
  • the transfer device (19) consists of a pneumatic drive (20) whose piston rod sets lever systems (21) in motion which change the position of sword-like plates (22).
  • FIG. 8 only two of the four lever systems and transfer swords (22) are shown. The transfer takes place so that when the pneumatic drive is extended (20) the sword-like transfer devices (22) act on the upper edge of the sack (1).
  • Figure 10 shows a cross section along the line X ⁇ X of figure 8. From this figure it can be seen that the expansion frame (10) fit into the edges of the box bag and the large container. It is thus possible to insert the box bag (1) into the large container (14) largely without wrinkles.
  • FIG. 1 An embodiment of the device required according to the invention is shown schematically in FIG.
  • the box bags (1) used are inserted into the brackets (3,3 ', 4,4') of the trolley (2). These trolleys (2) are guided on a first magazine track (5).
  • the brackets (3,3 ') and (4,4') are each so far apart that at least one side of the box bag (1) can be clamped spread out between them.
  • the clamping points (3 and 3 ') consist of a fixed part (23, 23') which is rigidly connected to the linkage of the trolley (2) and a resilient part (24, 24 ') that allows the clamping of packaging material .
  • the clamping points (4,4 ') are designed in a similar way. In contrast to the fixed parts (23, 23 '), the fixed parts (25, 25') are, however, movable about the pivot points (38, 38 '), the resilient parts (26, 26') correspond to the springs (24, 24 ') .
  • the trolleys (2) must be able to be easily moved back and forth on the magazine track (5), for example by means of rollers or sliders or the like.
  • the shape of the magazine track can be that of an open rail track.
  • the use of so-called C-rails for guiding the rollers of the carriage (2) has proven itself, for example.
  • the trolleys (2) are moved using a pushing device (27) which has a reciprocating drive (28).
  • the trolleys (2) are moved on the first magazine track (5) by actuating the drive (28) to which a ratchet (29) is connected, which can interact with the trolleys (2).
  • the pushing device (27) By actuating the pushing device (27), the trolleys (2) are transported on the magazine track (5) until the first carriage reaches the stop (6) of the first magazine track (5).
  • the now empty trolley (2) must be lifted onto a second magazine track (16).
  • This can be done, for example, by a lifting device (15) which can raise the end piece (30) of the magazine track (5) including the stop (6) up to the height of the second magazine track (16).
  • a pneumatic drive (31) in turn serves to drive the lifting device (15).
  • the empty trolley (2) then continues on the inclined magazine path (16) up to an actuatable stop (32) if there are no further empty trolleys (2) on the magazine path (16).
  • the connection between the first magazine path (5) and the second magazine path (16) is established by a movable path part (33) which can be pivoted about the axis (34) with the aid of a movement device (35).
  • the empty trolleys can continue to roll up to a stop (36) with the part (33) raised and the stop (32) open. After closing the Stop (32), the web part (33) can then be lowered to the height of the first magazine web (5) and the trolleys (2) can be transferred from the movable web part (33) to the first magazine web (5).
  • the pulling device (7) is indicated opposite the stop (6) and can be advanced with its gripper arms (8, 8 ') with the aid of a device (not shown) up to the vicinity of the stop (6).
  • the grippers (8,8 ') are actuated via an actuator (37).
  • the piston of the actuator (37) extends, the gripper arms (8, 8 ') swivel upwards and can thus be lifted over the first edge of the sack, which is located in the trolley, which is at the stop (6).
  • the edge of the bag is held resiliently by the grippers.
  • the gripped bag can be pulled out of the clamping points (4,4') of the trolley without the clamping in the grippers (8,8 ') changing .
  • the clamping points (4,4 ') swivel about their axes (38,38 1 ).
  • the grippers (8, 8 ') are also intended to hold one side of the clamped sack (1) in a spread-out position, so it is necessary for the grippers (8, 8') to be almost as far apart as one side of the box sack is wide.
  • This spreading device (9) preferably consists of four spreading elements (10, 10 ') which can be moved via a drive system (11).
  • the spreading device (9) is fastened to a movement device (13) which at least moves the spreading device (9) vertically
  • the expansion elements (10) are movably attached to the movement device (13) via axle bolts (39) and are movably connected on their lower side to expansion elements (10 ') which are movably connected to the piston of the drive (11).
  • the position of the expansion elements (10) can be changed by moving the drive (11).
  • the position of the expansion elements (10) in the retracted state can be seen from FIG. 4, in FIG. 5, with the piston rod of the drive (11) extended, the position of the expansion elements (10 and 10 ') in the tensioned state.
  • the four spreading elements (10) act along the edges of the box sack, as was shown in the schematic view in FIG. 10.
  • the expansion elements (10 and 10 ') have a circular cross section. However, the cross section of these elements does not have to be circular, for example in FIG. 12 a spreading element (10) is shown which was made from an angular profile.
  • Actuable clamps (12) are attached to the expansion elements (10). It is actuated via a lever system (40) by a drive (41), which was shown again in FIG. 11 as a pneumatic drive.
  • the edge of the sack is held in the vicinity of each edge of the sack (1) by two actuable clamps (12 ', 12 ") which are connected to the lever system (40) via an angle piece (42).
  • actuable clamps (12 ', 12 ") are connected to the lever system (40) via an angle piece (42).
  • the actuatable clamps (12) and (12 ', 12 ") are attached to the expansion elements (10) at such a height that they just touch the upper edge of the bag (1). can pinch.
  • knives (18) which can be actuated are provided on each expansion element (10) at the level of the upper edge of the clamped sack.
  • a precise arrangement is shown in FIG. 12; here the knife (18) acts directly through a slot in the expansion element (10).
  • the knives (18) are also connected to drives (44) via lever systems (43). These drives, via the lever systems, enable the knives (18) to be swung out and the upper edge of the sack to be cut into the edges at a predetermined length.
  • a transfer system (19) is also provided, which consists of a drive (20) and associated lever systems (21) as well as pivotable swords (22).
  • FIG. 11 shows only two of these lever systems and two of the swords which can act on the upper edge of the sack.
  • the swords (22) are elongated, ruler-like structures which allow the film material to be transferred under the holding devices (17) of the large container (14).
  • the large container (14) in FIG. 11 has holding devices in the form of long leaf springs (17) on its upper edge, which are capable of resiliently holding the cut edge of the box bag (1).
  • the large container (14) can be used for transferring or receiving the box bag (1) by a movement device, not shown, such as a roller conveyor or the like can be transferred to the exact location of the handover. This exact location can e.g. be fixed by suitable stops or the like. It is not absolutely necessary that this transfer location, as shown in FIG. 11, be within the actual device, i.e. between the rail track (5) and the pulling device (7) and below the spreading device (9). A transfer location at another point would also be possible. It would only have to be ensured that the movement device (13) of the expansion device (9) can carry out corresponding movements to another transfer location.
  • the device shown and described has a number of drives. They have mostly been shown in the figures as pneumatically operated movement devices. Since they usually only have to perform a reciprocating movement, such a type of drive should be particularly simple and at least prone to failure. However, it is also possible to carry out these movements, for example by means of electrical servomotors, for example in connection with gears or tooth chains or the like.
