Definitions

  • the invention relates to a method for filling from a flexible, flat material formed packaging units, such as plastic bags or paper bags, with soft objects and a device for carrying of the procedure.
  • Baby diapers, sanitary napkins and the like are packaged for a long time using packaging machines in which these Products are packed in bags.
  • the bags are in the Packaging machine opened and the products are in this opened bag inserted. Feeding the bags to the packaging machine is done by hand in practice.
  • the bags are placed in bundles in the packaging machine.
  • the bundles are held together with removable rivets and are also shipped packaged in a box, for example.
  • the people holding the bundled bags of the packaging machine feed must loosen the rivets. If these rivets are not loosened accidentally, this can happen a stop of the packaging machine and thus an interruption in production cause. So that the bags are bundled can, there are a tab with holes on each Perform rivets required. These tabs mean an additional material consumption. Being a disadvantage too viewed that bundling the bags and sending them Bundle in boxes is expensive.
  • EP 0 960 816 A describes a device for feeding Bags known to a station. This one all-round transport device with a variety of brackets on. These brackets are on the transport device attached and designed to hold a holding member. Several bags are attached to two holding links in the area of their open ends to form a stack of bags. In this device, the bags are bundled Station or a packaging machine supplied.
  • the invention has for its object a method and to create a device for further processing of packaging units and especially bags further simplified and enables higher performance.
  • the invention is achieved with a method according to claim 1.
  • the individual Packaging units formed a stream of shingles.
  • Shingled stream can be a station, especially a packaging machine fed much more efficiently and quickly are packaged in bundles.
  • a stream of shingles with conveyor belts can be used transport comparatively long distances and very quickly. Rivets and tabs to hold the packaging units together are not required.
  • the packaging units are temporarily stored as a stream of shed become.
  • a shingled stream enables one in particular high density and thus a transport with a comparatively small volume.
  • Intermediate storage is then particularly advantageous if according to a further development of the invention the Shed stream wound up into a roll for interim storage becomes.
  • a large number of packaging units can be placed on such a roll and in particular bags stored and also transported become. This saves packaging material.
  • the transport is comparative Cheap.
  • the making of suitable roles is known per se in the printing processing industry. For this reference is made to CH 682 657 A, for example. This discloses a method and apparatus for manufacturing of windings with which printed products in the shingled stream, for example Newspapers are held together.
  • the device according to the invention has means for forming a Scale flow.
  • a wrap is then special stable if it has a core as well as at least one winding tape having.
  • a particularly high stability of the winding is then achieved if according to a development of the invention the wrap has lateral guide means.
  • these guide means Preferably have these guide means arranged at a distance from each other preferably rotating side walls.
  • the stability of the Wickels can be increased even further if according to further training of the invention, the winding tape is wound up in a wave shape is. Preferably two are spaced in this way arranged tapes used.
  • the formation of the winding and the unwinding are preferably carried out by means of a so-called carpet, which is an endless Tape.
  • This carpet preferably forms a seesaw and with this the shingled stream is fed to the winding and at the same time the winding is driven with it.
  • the winding can be driven via a winding core.
  • the winding is formed in one direction of rotation and in the other Direction of rotation is handled.
  • the winding as well as the unwinding is preferably carried out on a winding frame.
  • the transport and the interim storage of the wrap can be done with or without a winder block respectively. Transport is preferably carried out without a trestle. Since tens of thousands on such a wrap of bags can be arranged is a very rational Storage and transport possible.
  • Unwinding one Winding can be done very quickly, i.e. there can be packaging units and especially bags with a very high one Performance of a station and in particular a packaging machine be fed.
  • the feed is continuous and automatic possible.
  • Vehicles for docking and undocking of such Winding and storage systems are known per se.
  • the bags 16 are preferably made of a comparatively thin plastic film manufactured and have an opening 16a and opposite this one floor 16b. Side edges 16c are for example formed by welding. When empty the bag 16 is flat and preferably rectangular. Such Bags 16 are used in particular for packaging baby diapers, Sanitary towels, towels, toilet paper and other products used.
  • the bags 16 are filled in one Fig. 1 shown packaging machine 15. Also such machines 15 are well known to those skilled in the art. In this, for example the product is filled into the bag 16 through the opening 16a. The opening 16a is then closed, for example by welding closed.
  • the scaled in the machine 14 Formation-prepared bags 16 must be a packaging machine be fed.
  • This device has a drive about an axis 23 Wheel 22, the gripper 24 movable on its circumference has.
  • a bag 16 is formed on the underside of the stack 21 deducted and in the direction of arrow 25 down on endless conveyor belt 7 filed.
  • the speed of the conveyor belt is so on the withdrawal speed of the wheel 22nd matched that the bags 16 in a scale formation and thus partially stored overlapping.
  • the conveyor belt 7 promotes this scale flow 19 in the direction of arrow 26.
  • the scale flow 19 is preferably formed so that the Bags 16 are transported with the bottom 16b ahead.
  • the Openings 16a of the bag 16 are thus each trailing. But there are also other scale formations and arrangements here possible.
  • the bags 16 can be on the side be staggered.
  • the conveyor belt 7 is arranged on a frame 1 and conveys the scale flow 19 to the winding device shown in more detail in FIG. 2 27.
  • the frame 1 can be part of the machine 14 his.
  • the formation of the scale flow 19 can thus in the machine 14 for example with the device shown in FIG. 6 be formed.
  • An execution is also conceivable, in which the scale flow is not in the machine 14, but instead outside of this is formed.
  • axis 9 On axis 9, for example, two are at a distance from each other arranged winding tapes 12 attached, the tension of a supply spool, not shown here, are unwound.
  • the wrap 13 can guided with the bracket 18 away from the rocker 4 and to the packaging machine 15 can be transported.
  • A is also conceivable Intermediate storage of the winding 13.
  • a fixed Winding block 8 the winding 13 is lifted off the block 8 and thus can be transported without a trestle.
  • Fig. 3 So that the wrap 13 is stable even when the bags 16 are made of thin plastic films, are shown in Fig. 3 on the winding core 10 laterally guide plates 29 or others suitable guide means arranged that are fixed to the winding core 10 are connected.
  • the guide plates 29 have in Direction of the axis 9 to each other a distance which is essentially corresponds to the width B shown in FIG. 5.
  • the Arrangement of the bag 16 can in the stream of shingles as before mentioned in different ways.
  • the bags 16 can with the floor area, the opening area or a side area be promoted in advance. It is preferable to ensure that a regular scale thickness across the width of the flow is present, so that the winding is approximately cylindrical Has shape. The spacing between scales can also be varied.
  • the winding is transported with these guide plates 29.
  • the winding tapes 12 can also increase the stability comparatively be wide. It is also advantageous if the Winding tape 12 are guided when forming the winding 13, that their mutual distance is changed. The tapes 12 then do not run rectilinearly in the winding 13 in the circumferential direction but according to Fig. 4 wavy. Through this wavy Arrangement of the winding tapes 12 becomes a more stable winding 13 reached. The amplitude of such a wavy arrangement is comparatively large and is, for example Length of a circumference of the roll 13.
  • the transport and a possible temporary storage of the Bag 16 from machine 14 to machine 15 thus takes place as a winding 13.
  • the corresponding 1 same as in the formation of the winding, mounted on a winding block 8 '.
  • the winding device shown in Fig. 2 27 can be used for unwinding driven in the opposite direction.
  • the bags 16 are put together with the winding tapes 12 as a shingled stream onto the rocker 4 stored and transported from left to right as in Fig. 1.
  • the bags 16 were running with the back 16b leading wound, the opening 16a is now leading when unwinding.
  • the shingled stream 19 'thus formed becomes the packaging machine 15 fed.
  • the pouch 16 removed from the scale stream 19 ', opened and with the intended Product filled.
  • the opening 16a is then closed, for example welded.
  • Another Conveyor 31 are the finished packs 30 of the others Processing fed.
  • the supply of the scale flow 19 'or the bag 16 for Machine 15 is preferably continuous.
  • Unwinding can also be done automatically and done very quickly. So it can also be very fast-working packaging machines 15 supplied with bags 16 become.
  • Winding can also be continuous and automatic as well as with a very high performance.
  • the winding core 10 and the winding tapes 12 can be used several times become.
  • There are also no special bundles on the bag 16 Parts such as tabs, rivets and the like are required. The cost of materials, especially packaging materials, can thus with the inventive method be significantly reduced.
