Definitions

  • the invention relates to a device for producing bags or sacks from a tubular film web made of thermoplastic, preferably provided with side gussets, with guide and preferred rollers, through which the front end of the tubular film web, each provided with a bottom weld seam, freely hanging in the vertical direction intermittently by one bag each.
  • the cooling section consists of two opposing, synchronously driven chain conveyors, the endless chains of which rotate around two sprockets each with a vertical axis of rotation and carry grippers at a distance, which pass through each other facing and lying in one plane inner chain runs of the two chains grasp the tube pieces provided with the bottom weld seams on opposite edges and convey them to a transfer device which conveys the bags into the filling station.
  • This known device is relatively expensive because two revolving endless chains with the associated drives must be provided, in which, however, only the grippers running over the mutually facing inner chain spaces serve to transport the bags and the ones via the deflection and drive wheels and the outer chain spaces running grippers have no transport function.
  • the object of the invention is therefore to provide a device of the type mentioned at the outset with a transport device forming a cooling section, the grippers of which essentially do no empty strokes during the intermittent drive of the transport device.
  • the transport device consists of a hub-like support piece with radial arms which is rotatably mounted about a vertical axis and at the free ends of which the grippers provided in pairs are arranged.
  • the cooling section according to the invention thus consists, as it were, of a cooling carousel which feeds the bag workpieces provided with the bottom weld seams and separated from the tubular path from the welding station on a circular path to a device for transferring the bag workpieces to the filling station.
  • the device according to the invention preferably has four radial arms, a welding device and a cutting device are located above the first station.
  • a sack that is already provided with a bottom seam is therefore inserted from above into the first pair of open grippers and is preferably gripped and cut off over a sack length.
  • a new bottom seam is then formed at the end of the tubular path, while the cooling carousel rotates intermittently through an angle of 90 ° and remains in this position until another sack with a bottom seam has been inserted into the subsequent station. This is repeated in a four-arm cooling carousel until the first station has rotated 270 ° in three cycles. At this point the bottom seam has cooled and the sack is transferred to a transfer device which transports the sack to a filling station.
  • the time required for this is therefore not greater than the time required to produce a sack and to enter the gripper.
  • the carousel according to the invention thus serves to cool the bottom weld seams formed.
  • the carousel design allows the device to be designed in a space-saving manner with a sufficiently long cooling section.
  • From GB-PS 919 392 is for the manufacture and filling of Sacks already known a carousel-like device that is incrementally incremented by an angular step.
  • the bottom seam is only welded when a bag length has been advanced, so that the cycle time is determined by the time required for the welding and by the time required to advance the tubular web by a bag length.
  • the known device also does not make it possible to change the format in a simple manner, since the welding devices forming the bottom seam are located at a constant distance below the grippers. A change in the format length therefore makes it necessary in the known device to adjust the height of the welding jaws.
  • the welding station is located above the grippers and the cutting device at a fixed distance from them, so that the desired format can be easily adjusted by the feed length which is effected in each case.
  • a station of the carousel forms the filling station, so that there is not enough time left for the bottom weld seams to cool down.
  • a similar carousel-like device for producing and filling sacks or bags is also known from DE-PS 26 08 456.
  • the grippers of a pair of grippers holding a bag or sack expediently have the same radial distances from the axis of rotation of the support piece. This configuration ensures that the bags or sacks hang tangentially on the carousel-like transport device, which enables the device to have a small diameter.
  • the arms carrying the grippers expediently have the same angular distances.
  • each arm of the device according to the invention forms the gripper pairs with the closest grippers of the adjacent arms.
  • the ends of the arms therefore do not need to be provided with support pieces, the width of which corresponds approximately to the width of the sack.
  • the ends of the arms can be provided with support pieces which have clamping jaws on their outer sides, which interact with movable clamping jaws which are fastened to levers which are pivotably mounted on the support pieces about vertical axes.
  • the movable clamping jaws of each pair of grippers are expediently connected to one another in an articulated manner by a coupling rod for executing synchronous opening and closing movements.
  • the pairs of grippers located in the welding station and in the transfer station are expediently opened and closed by a common actuating device. These pairs of grippers expediently perform synchronous opening and closing movements, since the delivery of a sack workpiece can take place in the time in which the next pair of grippers following in the direction of rotation picks up the last-produced sack workpiece.
  • the pairs of grippers located in the welding and in the transfer station lie next to one another and that the levers carrying the movable clamping jaws are acted upon by springs in the direction of their closed position and carry sliding blocks or rollers between them for opening the gripper is retractable a wedge-shaped spreader whose flanks form guides or cam curves for the sliders or rollers.
  • a frame-fixed opening and closing device can be provided for two pairs of grippers, so that none with rotating drive must be provided, which causes the opening and closing movements.
  • the expansible piece is expediently provided on a lever or the like by means of a pressure medium-piston-cylinder unit. is pivotally mounted about an axis fixed to the frame.
  • each lever is provided with a guide roller which, when it is pivoted out, runs into guide slots in a plate which is firmly connected to the arm.
  • This plate thus forms a securing plate which prevents damage to the device if the carousel should inadvertently be advanced by an angular step when the expansion piece is still in engagement between two sliders or rollers.
  • the hub is expediently provided with a drive pulley for driving it, over which an endless belt runs, the geared motor with the drive pulley for the belt being arranged between the welding and transfer station. Since the welding jaws do not transport a sack workpiece between the transfer and welding station, this cannot collide with the drive belt in this area either.
  • a rake fixed to the frame about a horizontal axis, which rake can be swung out with each feed stroke in such a way that the end of the tubular film web provided with the bottom seam of the Welding jaws can be loosened and passed freely through the downstream cutting and clamping devices.
  • the rake is expediently arranged in annular grooves of a preferred roller and can be pivoted about its axis of rotation.
  • the swivel movement supply of the rake can be derived from the opening movement of a jaw arranged above the welding device, so that the construction is simplified with regard to the swivel drive.
  • a frame 1 has side walls 2 and 3, which are indicated in FIG. 2. Both side walls 2, 3 are connected to one another by a crossbar 4.
  • This cross-member 4 carries approximately in the middle a downwardly projecting fixed axis 21, on which a swivel arm 5 is mounted near the cross member 4, which via a pressure-piston-cylinder unit 6, the cylinder of which is held by a support piece, in one of two possible end positions can be moved.
  • pivot arm 5 designed as an angle lever carries at its free end a molded part 5 'and is provided in its angular range with a locking roller 7.
  • the function of these parts is discussed further below in the description.
  • a further vertical axis 8 is attached to the crossmember 4, which carries a four-armed turntable 9 below the swivel arm 5, which can be rotated by a motor 11 in cycles by 90 ° in each case by means of a toothed belt 10.
  • the direction of rotation of the turntable is indicated by an arrow A in FIG.
  • Fig. 2 it can be seen that the freely projecting arms 9a of the turntable 9 forming a hub, as it were, carry molded pieces 12, each of which has two upwardly projecting pins 13.
  • a lever 14 is mounted rotatably about each pin 13 and is designed as a gripper 15 at its free end. Each of these grippers 15 rests under the force of the springs 16 on a counter surface 17, with each fitting being provided with two counter surfaces 17.
  • the mutually facing levers 14 of two adjacent arms 9a are functionally connected to one another via a link 18 such that the two associated grippers 15 open or close at the same time in order, for example, to be able to grip and hold a bag 19.
  • the grippers 15 are opened by the wedge-shaped or curved cam surfaces of the molded part 5 'of the support arm 5. If the support arm 5 is pivoted by extending the piston rod of the pressure medium-piston-cylinder unit 6, the molded part 5' presses the pressure rollers 20 connected to the levers 14 of the molding 12 apart so that the grippers 15 pivot about the pin 13 and detach from the associated counter surfaces 17. At the same time, the grippers 15 of adjacent shaped pieces are released via the handlebars 18. In the situation shown in Fig. 2 would therefore when the pressure medium-piston-cylinder unit 6 is actuated, the gripper units 15 facing the upper and the right edge of the drawing are released.
  • the safety roller 7 mounted in the angular region of the swivel arm 5 runs into a guide groove 22 of a locking plate 23 when the swivel arm is pivoted to open the grippers.
  • This locking plate 23 is securely connected to the turntable 9 by means of screw bolts 24, so that this is prevented from rotating by the locking roller 7 of the swivel arm 5, for as long as the molded part 5 'is between the rollers 20 of a molded part 12.
  • a hose 26 runs from a roll 25 from above into an inlet station 27.
  • This inlet station 27 is fixedly connected to the frame-shaped frame 1 and can be seen in more detail in FIG. 3.
  • 3 shows the central axis 8 of the cooling carousel and part of the turntable 9.
  • a hose section 19 provided with a bottom seam is clamped by the grippers 15 and the counter surfaces 17 of the turntable 9, but is initially still connected to the hose track 26.
  • the carrier 30 also has a knife groove 32 and a welding jaw 33.
  • a knife 34 dips into the knife groove 32 to separate the bag 19 from the tubular web 26, while a second welding jaw 35 interacts with the welding jaw 33 in order to provide the leading end of the tubular web 26 with a bottom seam.
  • the knife 34 and the welding jaw 35 are guided in parallel on one of the handlebars th second coupling rod 36 attached. Both coupling rods 28, 36 are actuated via pressure medium-piston-cylinder units 37.
  • a further clamping device is provided above the welding jaws 33 and 35, which clamps the tubular web 26.
  • This consists of a pivoting lever 39 provided with a clamping bar 38, which can be moved via a pressure medium-piston-cylinder unit 40.
  • An arm carrying a roller 41 is fixedly connected to the pivot lever 39, the roller 41 being at a distance from a guide piece 43 in the clamping position of the pivot lever 39.
  • This guide piece 43 is connected to a lever 44 which is held against a stop 46 via a spring 45.
  • the pivot point of the lever 44 lies on the axis of the preferred roller 47. It has a downward-facing shoulder which is designed as a counter-holder 48 to the terminal strip 38.
  • the pressure medium-piston-cylinder units 37 and 40 are first actuated after the formation of a bottom seam and a separating cut, and as a result the coupling rods 28, 36 and the lever 39 are pivoted away.
  • the roller 41 comes into contact with the cam surface of the guide piece 43.
  • This causes the counter-holder 48 to pivot in the direction of arrow C, which on the one hand releases the freely hanging end of the web 26 from the welding jaw 33 and on the other hand deflects it. This deflection ensures that the web does not collide with the carrier 39 when it is advanced by a sack length by the preferred rollers 47 and 51 at the next cycle.
  • the preferred rollers are provided with annular grooves 49, 50, into which stripping fingers 52 and 53 engage.
  • the fingers 52 of these fingers are held in place on the frame and the fingers 53 are attached to the counter-holder 48 as wiping rakes.
