Definitions

  • the invention relates to a device for feeding a singular sack from a storage area to a filling station with a closable filling funnel, in which a transport device provided with suction devices for opening and grasping the sack is provided, followed by a pulling device for pulling the sack onto the closable filling funnel is.
  • the bags are usually placed individually on a rigid shelf and from there are conveyed further by means of the transport device provided with suction devices in the direction of closable filling funnel or pulling device.
  • the bags slide off the shelf and bend downwards. This leads to the sack reaching the pulling device at an unfavorable angle, which is usually arranged pivotably about a horizontal axis.
  • a bag feed device with a movable shelf is also known.
  • the movement of the tray serves to transfer the sack to the transport device.
  • the aim of the invention is to remedy the shortcomings of the known devices and to propose a device of the type mentioned at the beginning in which a symmetrical opening of the bag is ensured, in particular when the bag is transferred to the pull-up device.
  • this is achieved in that the transport device provided with the suction devices and the tray are coupled to one another in a movement-locking manner, so that each sack is at least partially supported during transport to the pull-up device.
  • the pulling device which is optionally provided with expandable holding devices for receiving the sacks, is arranged so as to be pivotable about a horizontal axis
  • the transport device provided with the suction cups and the tray can be pivoted, preferably pivotable about a common axis are arranged.
  • the tray in its end position closer to the pulling device, be seen from its trailing edge in the transport direction of the bags, trailing down towards its leading edge and essentially tangential to the position of the pulling device or its holding members in its takeover position.
  • the support has an extension in the transport direction of the sack which corresponds essentially to half the length or height of the sack.
  • the sacks 2 are stacked in the magazine 1, the individual sacks 2 or smaller packages of sacks being arranged laterally offset, as can be seen from FIG. 2.
  • the stack of sacks 2 can always be held in a position by means of the bottom 5 which can be raised and lowered, in which the uppermost sack 2 is located in a position near the upper end of the magazine 1.
  • a chain grate 6 runs around the magazine via deflection wheels 11, one or a pair of which is driven.
  • This chain grate 6 serves to transport the bags 2 in the direction of the predetermined transfer position 7 and is provided with grate fields 8, in which the two chains are connected with grate bars 10, which are separated from one another by sections 9, in which no grate bars 10 are arranged .
  • These sections 9 are expediently dimensioned longer than the magazine in the transport direction of the chain grate 6.
  • a removal device 12 is arranged above the magazine and is essentially formed by a lever which can be moved by means of a cylinder-piston device and which carries a suction head 13 at its free end.
  • the removal device 12 is controlled in such a way that the angle lever engages with its suction head 13 through the chain grate 6, while a section 9 passes underneath the removal device 12 without grate bars.
  • the top sack 2 of the magazine 1 can be raised and brought with its one end into a position above the chain grate 6.
  • the subsequent grate field 8 lifts, as can be seen from FIG. 1, the sack 2 raised at one end over its entire length, after which the suction head 13 is relaxed, so that the end of the sack 2 falls onto the chain grate and from it is taken away.
  • the chain grate 6 pushes the sack 2 to a further transport device 14, which is essentially formed by a plurality of circumferential belts 15, one strand of which runs just above a table 16. These belts 15 are driven intermittently, with a sensor device (not shown) in conjunction with a control device (also not shown) ensuring that the drive is stopped and the isolated sack 2 lies in the position shown in full lines in FIG. 1 is coming.
  • a device for aligning the Sackes activated transversely to the table 16 which is essentially formed by two pairs of stops 40, 40 ', 41, 41', the two pairs of stops being movable against one another. These stops are formed by corresponding slots in the table 16 passing through fingers, the drive of which is controlled by a control device controlled by sensors (not shown) which respond to a bag 2.
  • a sack 2 is gripped by a further transport device 17, the sack 2 in the embodiment shown partly on the table 16, or the stopped belt 15 and partly in an end position shown in full lines on the table 16 subsequent tray 18 rests.
  • the sack 2 protrudes somewhat beyond the edge 19 of the tray facing away from the table 16, which edge, as seen in the transport direction of the sack, runs forward.
  • the transport device 17 engages with its suction devices 20, with which it grips the bag 2 and at the same time opens the bag 2 by increasing the distance between the suction devices 20.
  • suction cups 20 are held in a frame, not shown, which is held pivotably about an axis 22 via a pair of angled arms 21, this axis running parallel to the plane of the shelf 18.
  • the axis 22 is arranged in the vertical direction lower than the tray 18 and in the horizontal direction closer to the mounting device 30 than the edge 23 of the tray 18 trailing in the transport direction of the bags 2 in its end position closest to the table 16.
  • the axis 22 lies further away from the pull-up device 30 in the horizontal direction than the edge 19 of the tray 18 leading in the transport direction of the bags 2 in its end position approximated to the pull-up device 30.
  • a cylinder-piston arrangement 24 is provided, with which the transport device can be pivoted between the table 16 and the pull-up device 30, the bag 2 remaining open during the pivoting of the transport device in the direction of the pull-up device 30.
  • the mounting device 30 essentially consists of two spreading arms 33 which can be pivoted about an axis 32 which runs parallel to the opening plane of the closable hopper 31 and parallel to the pivot axis 22, which are essentially mutually movable parallel to the axis 32 and carry spoons 34 at their free ends, with which the gussets of the bags 2 are pressed outwards.
  • the spoons 34 of the pulling device 30 engage in the opening of a sack 2 or the sack 2 is pulled over them by means of the transport device 17, these are spread apart, so that the sack is held by the spoons 34. Thereafter, the suction heads 20 of the transport device 17 can be relaxed so that they release the sack 2, after which the transport device 17 can be pivoted back into its starting position, in which it is approximated to the table 16.
  • the puller 30 now pivots towards the closable hopper 31 and thereby pushes the bag 2 over the closable hopper 31, after which the clamping devices 35 can be pressed against it, with which the walls of the bag 2 are pressed against the outer sides of the closable hopper 31. Thereafter, the pulling device 30 pivots further upward, whereby the spoons 34 are pulled out of the bag 2.
  • the puller 30 pivots again into its takeover position shown in full lines, in which the spoons 34 are inserted into the next sack, the spoons 34 reducing their mutual distance during the swinging back.
  • the position of the pivot axes 22 and 32, and the length of the respective arms 21 and 33 are chosen so that the tray 18, which is part of the transport device 17, is substantially tangent to the circular arc described by the spoons 34 in the transfer position of the transport device 17th and the winding device 30 extends.
  • the tray 18 itself does not need to support the sack 2 over its entire length or height, it is sufficient to as shown in Fig. 1, if this is about half as long as the sack 2. Any kinking of the sack over the trailing edge 23 of the tray 18 is not disturbing, since the sack 2 is supported in the area of the sack opening and the side gussets of the sack are therefore opened symmetrically. This enables the bag 2 to be taken over smoothly by the pulling device 30, which enables the bag 2 to be pulled onto the closable filling funnel 31 properly. The latter is again required for proper filling of the sack so that it can be closed without wrinkles.
