Definitions

  • the invention relates to a sack feeding device, in particular for a stationary industrial sewing machine, welding device or the like for making sack closures, consisting of a substantially horizontally arranged support plate, extending in the longitudinal direction of the support plate through slot, arranged on both sides of the passage slot conveyor for gripping the bags below the suture edges to be sutured and for feeding the sacks to a sewing unit, welder or the like, a gear box connected to a drive motor near the entry area of the through slot, the output shafts of which are in operative connection with the conveyor and in motion offset, and two opposed, drivable, rotating about substantially vertical axes cutting blades.
  • sack feeders for sack-known closures which have stationary arranged cutting blade. These are integrated into the transmission unit and are directly driven by the transmission, which also serves to actuate the conveyor. Thus, the known device can only be used to pick up the sewing material in the sack feed, to cut it in the subsequent unit and then to sew it on in the subsequent sewing unit.
  • a bag feeder according to the preamble of independent claim 1 is known from the document US-A-3,720,559 , When using stationary sewing machines for bag closures, it often happens that the upper bag edges do not need to be circumcised or circumcised. In such cases, then another stationary sack feed must be used, which has no built-cutting blades.
  • the invention is therefore based on the object to make such a sack feeding device such that it is suitable for the use of both said methods, that is, that they can work without major set-up both with cutting knives and without cutting knife.
  • this object is achieved in that the rotating cutting blades are mounted in a separately formed knife block and that the knife block with the cutting blades relative to the gear box between an active and an inactive working position is displaceable and fixable in its predetermined working positions.
  • the user has the option of cutting the sewing material prior to entering the sewing unit or the welding device, or to completely dispense with cutting the sewing or welding material.
  • Such a device is particularly suitable for those cases where the user wants to set up only a single machine for different operations.
  • the knife block is slidably disposed relative to the gearbox in the vertical direction between a lower and an upper working position.
  • the knife block can be equipped with a profile carrier with at least one vertical guide groove, while on the gear box, a provided with a clamping lever angle piece is arranged.
  • the clamping lever has expediently engaging in the guide groove fastener, which is fixable in the guide by actuating the clamping lever.
  • a separate drive may be provided which is directly connected to the knives. but preferably the knife drive is effected by the already existing conveyor. This is done by arranging a rotatable force transmission element in the region of at least one of the two blade axes, which can be driven by means of the conveying device and selectively coupled to the corresponding blade axis.
  • the lower end face of at least one of the knife axes may be provided with an upper part of a positive plug connection, while the rotatable power transmission element is designed as a complementary lower part of the positive plug connection, wherein the upper and lower parts of the plug connections in the lower operating position of the knife block coupled together are.
  • the endless drive elements can be designed as link chains whose mutually facing strands for transport serve the sewing material.
  • link chains and belt or belt-like driving elements can be used, which are driven by means of toothed belt wheels.
  • the endless link chains are preferably driven by seated on the output shafts of the gear box tooth or sprockets.
  • the rotational movement of the lower part of the positive plug connection is preferably derived by means of a transmission element of the endless drive element.
  • a transmission element may be provided a toothed or sprocket, which is in communication with the corresponding link chain and converts the linear movement of the link chain in a rotational movement of the lower part of the connector.
  • the bag feed device according to the invention which is used in particular in connection with a stationary industrial sewing machine for the production of bag closures, has a horizontal support plate 20, through the middle region of which a through slot 21 extends.
  • the passage slot 21 serves to receive and supply the in Fig. 1 Not shown, which is introduced on the right side of the support plate 20 in a wedge-shaped widened entrance area 22 and then transported to the left end, where it is closed in a sewing unit, not shown in the drawing.
  • the sewing unit has been omitted from the drawing for reasons of clarity.
  • a plurality of mounting holes 23 are shown, on which various functional units, such as guide rails, a Umfalt issued, a Reiterbandapparatur, photocells or the like can be tightened. Then follows the sewing unit still or a welding unit to close the bags or bags.
  • a gearbox 1 is mounted on the support plate 20, to which a drive motor 3 is flanged.
  • a knife block 2 which is adjustable relative to the gear box 1 in height and two round, rotatable cutting blades 11 and 14 carries, wherein the cutting blades are arranged transversely to the conveying direction of the sewing material opposite each other.
  • one knife is designed as a lower blade 11 and the other as upper blade 14.
  • a conveyor which serves for gripping the bags below the seam edges to be closed or to be closed and for feeding the bags to the subsequent sewing unit or to other processing units.
  • the arranged in the region of the passage slot 21 of the support plate 20, serving as Nähgutzu Replacement conveyor 6 consists of two link chains 24, whose facing strands seize the fabric and lead through the entire device.
  • the endless link chains 24 are driven by means of the motor 3 and the output shafts 4 of the transmission box 1 provided in the transmission.
  • Fig. 2 only one of the two out of the gearbox 1 led out output shafts 4 is shown. This has at its lower end a toothed or sprocket 5, which meshes with the individual members of the link chain 24 and drives them in the conveying direction. The same happens over the second in Fig. 2 not shown output shaft 4, which is driven in opposite directions and with a corresponding toothed or sprocket 5, the second link chain 24 drives.
  • the linear movement of the feeding device 6 serving for conveying means 6 is converted by means of a toothed or sprocket 7 in a rotary motion.
  • the lower part of the positive plug connection 9 is constantly driven, that is, this, when the conveyor 6 is turned on, constantly rotates.
  • the shaft of the lower blade 11 has at its lower end to the upper part 10 of the connector, which is positively coupled with the lower part 9 of the connector.
  • the coupling and disengaging takes place in that the knife block 2 is movable up and down relative to the stationarily arranged gearbox 1.
  • the upper blade 14 rests on the lower blade 11, so that the fabric in the in Fig. 2 shown position of the knives 11 and 14 can be cropped at its upper end.
  • the knife block 2 is moved relative to the gearbox 1 upwards, so that the two parts 9 and 10 of the connector separated from each other and the knives 11 and 14 in the in Fig. 1 shown raised position in which they are outside the passage area of the sewing material.
  • Fig. 6 and 7 showing a rear perspective view of the device, the adjustability of the knife block 2 relative to the gearbox 1 in the vertical direction between a lower and an upper working position is illustrated.
  • a profile support 17 which is equipped with at least one vertical guide groove 25.
  • the gearbox 1 also has on its rear side a profile carrier, which in the FIGS. 6 and 7 is marked with the position number 18.
  • the profile carrier 18 is provided with at least one horizontal guide groove 26.
  • an angle piece 16 is fixed by means of screws 19, which abuts against the back of the profile block 17 connected to the knife block 2.
  • the knife block 2 can be moved up and down in the vertical direction, wherein in Fig. 6 the coupled or active working position of the knife block 2 is illustrated while Fig. 7 the decoupled or inactive working position of the knife block 2 shows.
  • the upper part 10 of the positive plug connection must first be aligned in alignment with the lower part 9 of the positive plug connection.
  • the knife block 2 is thereby fixed in the two coordinates extending in the horizontal direction.
  • To adjust the vertical coordinate of the clamping lever 15 is released and the knife block 2 is moved so far until it assumes the desired height. In this position, the clamping lever 15 is tightened again by hand, so that the knife block 2 is fixed in the required height.
  • the fabric is introduced into the extended entrance area 22 of the passage slot 21, which in the present case are bags 27.
  • the upper edges of the bags 27 can be brought into a predetermined position with an upstream bag spreader so that they can be easily inserted into the entrance area 22 of the support plate 20.
  • Knife block 2 At the in Fig. 8 view is located the Knife block 2 in its lower working position, in which the knives 11 and 14, as described above, are driven. The upper edges 28 of the passing bags 27 are thereby trimmed and the debris 29 is removed. In a following sewing unit, not shown, the upper, cropped edges are then closed.
  • the upper edges can then be folded as needed and then sewn in the sewing unit.
  • the newly developed Sackzu Swissvortechnische invention offers considerable technical progress, since according to their flexibility, the fabric of the desired application in one and the same machine can be processed accordingly, the upper sack edges can either be circumcised on the one hand and remain uncircumcised on the other hand.
  • the knife block 2 can be brought by simple manual operation of the clamping lever 15 very quickly in the desired working position, whereby no costly conversions of the machine are required. This eliminates additional set-up times and set-up costs.
