Definitions

  • the present invention relates to a machine for wrapping a group of containers, such as cans, which are arranged beside each other so that, viewed from above, they mainly form a rectangle, in a material of foil type, such as shrinkable foil, the containers then being fed into the machine in the form of one single row.
  • a material of foil type such as shrinkable foil
  • a group thus formed is enclosed in two sheets of shrinkable foil in such a way that the group is placed on one of the sheets and the other sheet is placed on top of the group. Adjacent edges of the two foils are fastened to each other by means of welding.
  • the wrapped group is thereafter subjected to heat, and the wrapped group forms a rigid pack.
  • This pack can thereafter quite simply be placed on a loading pallet without any risk that the wrapping will break.
  • a number of packs prepared in this way can thus be placed on a loading pallet, in several layers, just as if each pack had been a carton. It is an extremely simple and cheap method of wrapping and transporting containers. Hitherto, wrapping of containers in material of foil type has been carried out manually, which is extremely time-consuming and expensive, owing to high wages, but in spite of this, it is cheaper than other packing methods.
  • the purpose of the present invention is to create a machine that, without any manual influence, achieves the wrapping of said groups in a material of foil type.
  • the machine according to the invention is designed for plastic 'shrinkable foil, but it should be obvious that it can also be used for foil of other materials, such as e.g. aluminium, paper and the like.
  • the parts that will be varied are the members which join the adjacent edges of the foil together.
  • the present invention is characterized by a number of different units, which carry out different operations.
  • these units comprise the parts of a complete machine, but can also comprise independent units, which can be used in other, future machines.
  • the units comprised in the machine are thus not limited to the present machine.
  • the machine according to the present invention is characterized by a dividing unit for dividing said single row of containers into two rows, of a group-forming unit for forming said groups of containers coming from said two rows, of a blocking unit to prevent the feeding of a formed group, by a foil unit containing two rolls of foil located transversely in relation to the conveyor track along which each group formed is to be fed, one of the rolls then being located over the conveyor track and the other under the conveyor track, and the free ends of the two foils then being joined to each other through a transversal opening in the conveyor track, by a conveyor unit which transports the group formed past said transversal opening, by a first welding unit for making a transversal weld joining adjacent foil surfaces at the rear end of a formed group, of a tensioning unit, which stretches adjacent foil surfaces along the sides of the group, by a second welding unit which welds the last-mentioned foil surfaces, possibly a second conveyor unit which transports said group to or adjacent to said second welding unit and possibly by a shrink

  • the conveyor track 1 can consist of an endless belt, and coacts with two vertical walls 3 and 4, so that the containers are guided transversely. These two walls are usually at a distance from each other that corresponds approximately to the diameter of a container 2, and then at the part of the conveyor track which is to the left of the section shown in the figures. In these the distance is greater than the diameter of a container 2 and then preferably 1 /2 times the diameter of a container.
  • a wheel 5 is arranged, which is fastened to a shaft 6, which wheel is given a rotation in the direction indicated by the arrows 7 and 8.
  • the wheel is provided with a number of peripheral recesses 9.
  • Each recess has a width along the periphery corresponding approximately to the diameter of a container 2 and a depth corresponding approximately to one-half of the diameter of the container.
  • a peripheral edge 10 on the wheel 5 which has a length corresponding approximately to the diameter of a container 2.
  • an extra wall 11 is arranged, which presses the containers 2 against the wall 3.
  • This wheel is rotatable around a vertical axle.
  • every other container will be fed to the conveyor track which is limited by the walls 4 and 13, and the intermediate containers to the conveyor track which is limited by the walls 3 and 13.
  • the function of the wheel 14 is to reduce the contact friction between a container and the wall 13 at its left end.
  • the wheel could be eliminated without any major disadvantages, but it is an advantage to have it.
  • the reason for the use of the wheel 5 is that, through the use of same, it is avoided that containers which have been fed in will become locked together at the transfer to the two different conveyor tracks, which can occur at intermittent operation of the conveyor belt 1.
  • the containers from the two conveyor tracks are fed to a group-forming unit.

  • the axle can be connected to a driving member, which makes the axle turn in the direction indicated by the arrow 16.
  • said driving is not required, owing to the fact that at the mouth of the last-mentioned channel the containers are driven out on an endless conveyor belt 17, which passes by an idler 18.
  • the wheel 15a is provided with a number of groups of recesses, which groups are arranged after each other along the periphery of the wheel. Each group has three different recesses 19, and 21, which are identical for each group and have different depths. The number of recesses corresponds to the number of compartments 22, 23 and 24 to which the containers are to be fed. If more than three compartments are desired, each group of recesses in the wheel 15a will amount to a number corresponding to the number of compartments.
  • the different compartments 22, 23 and 24 are formed by the walls 26, 27, 28 and 29. Said walls extend towards the periphery of the wheel in such a way that containers located in recesses of the type which has been given the reference designation 21 go into compart ment 22, that containers located in recesses of the type which has been given the reference designation 19 go into compartment 23 and that containers located in recesses of the type which has been given the reference designation 20 go into compartment 24.

  • In the front end of each of the bars 117 and 118 there is a transversely directed finger 120 and 121, respectively, arranged, which are directed inwards.
  • each finger a line 122 is fastened, which runs rearwards, parallel to the bars 111 and 112.
  • the line 122 runs on a wheel 123, which is rotatable around a vertical axle 124, and also around a vertically arranged wheel 125, which is rotatable around a horizontal axle 126.
  • a weight 127 is fastened at the free end of the line 122.
  • a corresponding line with wheel and weight is arranged at the upper side of the conveyor track which is shown in FIG. 18.
  • the two foils 64 and 65 are shown, as well as an endless belt 127, arranged as an extension of the surface 99.
  • the group-forming unit described in FIGS. 16, 17 and 18 functions in the following way. It is assumed, however, that only one of the pushing members is functioning, and that only one of the belts, 98, is operating. When now the belt 98 is in motion, containers 2 are fed by means of this to a position, where the foremost container is in front of the blocking member 110. When this has taken place, the pushing member starts to function, and pushes on three containers, as shown in FIG. 17. The first longitudinal row is pushed in so far that three longitudinal rows can be placed side by side on the surface 99. When the first container is in position, the pusher 100 returns to the position shown in FIG. 16, after which the belt 98 starts up, and feeds three new containers to the same position as the foregoing containers.
  • the pusher 100 functions anew.
  • the last row of containers is pushed onto the surface in the same way as has just been described.
  • the belts 97 and 98 also operate continuously.
  • the first row can also be pushed in so that it just comes onto the surface 99. It is then moved farther in on the surface 99 by the following rows when these are pushed in.
  • FIG. 18 the finished group being displaced is shown.
  • the finished group is first in contact with the blocking unit 110, and cannot be displaced at all until the blocking device has assumed its non-blocking position. It should be obvious that a formed group can have a longitudinal row that contains more than three containers, as well as a width that exceeds three containers.
  • the group is, of course, formed more rapidly.
  • the non-blocking position is assumed only after the pusher 109 has come into contact with the group from the rear, but said position can also be assumed before said contact.
  • the plates 113 and 114 have also come into contact with the corresponding cleats 119, which involves that the pusher takes along the bars 117 and 118, with their fingers and 121.
  • the fingers move the blocking foil forwards, as is clearly shown in FIG. 18.
  • the conveyor unit moves the formed group to the position shown in FIG. 18.
  • the conveyor unit leaves the formed group, and the group is sealed at its rear end in a way corresponding to the way shown in FIG. 11. Thereafter the enclosed group is transferred to the second welding unit, where the group is thus to be welded along its sides.
  • the tensioning unit consists of two identical parts, which are arranged on each side of the enclosed group at the second Welding unit. Each part consists of two arms 128 and 129, which extend parallel to the longitudinal direction of the conveyor belt 127. Each arm has one end fastened to a shaft 130 and 131, respectively.
  • Each shaft is moreover arranged at right angles to its arm, and each is rotatably supported in a bearing member 132 and 133.
  • a wheel or, alternatively, a sprocket, 134 and 135, is fastened.
  • a line 136 or, alternatively, a chain which has One end fastened to a spring not shown, and the other end of which is anchored, runs over the wheels or sprockets.
  • the other end of the line 136 is fixed to a rod 137 of a hydraulic device or, alternatively, to a pneumatic device 138, which can give the line a movement.
  • the two shafts 130 and 131 are arranged at such a distance from each other that the free ends of the two arms 128 and 129 can be arranged facing each other. This is the starting position of the arms.
  • the parts 139 and 140 respectively are arranged, which are rotatable around the axles 141 and 142, respectively, which are parallel to the longitudinal direction of the arms.
  • a stick 143 and 144 is arranged at each part 139 and 140.
  • Each part 139 and 140 contains a spring 139a and 140a, respectively, which strives to turn the two sticks 143 and 144 into a position which is parallel, and at right angles to the surface 127 of the conveyor belt.
  • This blocking member 145 has a blocking action only when the free ends of the arms 128 and 129 have the position shown in FIG. 20, which shows the starting position of the arms.
  • the tensioning unit described functions in the following way.
  • the hydraulic member 138 is actuated in such a way that the rod 137 is drawn into the hydraulic device 138.
  • the two arms 128 and 129 are then given a movement upwards, to the position shown in FIG. 21.
  • the blocking member 145 loses its blocking effect, which has the consequence that the sticks 143 and 145 are turned inwards towards the conveyor track 127, so that the sticks will be parallel to the surface of the conveyor track.
  • the second part of the tensioning unit located on the opposite side, functions in an identical way.
  • the sticks at the two part units put opposite surfaces which are to be welded together at the second Welding unit into contact with each other, through streching from inside.
  • the arms are returned to the starting position, and the sticks then also return to their starting positions.
  • the containers 2 in the lastmentioned embodiment can be transferred to the surface 99 in any appropriate way whatsoever.
  • the lines 12 and the fingers 120 and 121 have been replaced by two supporting rules, which are movable transversely and parallel to the direction of movement of the belt 127.
  • the rules have such a position along the conveyor track that, when a group of containers is wrapped in foil, the whole group is located between the supporting rules.
  • the two supporting rules assume such a position transversely that the group can just barely pass through. After the wrapping has been completed, the rules move away from each other.
  • a machine for wrapping in a foil a group of containers arranged beside each other so that viewed from above each group substantially forms a rectangle with the containers being fed into the machine in a single row along a conveyor track which has an endless belt serving as its floor and which has side walls, the machine comprising in combination:
  • group-forming means for forming said groups of containers coming from said two rows
  • a foil unit including two rolls of the foil located transversely relative the conveyor track with one of the rolls located over and the other located under the conveyor track and with free ends of the two foils joined to each other through a transverse opening in the conveyor track,

  • first welding means for making a transverse weld joining adjacent foil surfaces at the :rear end of the formed group
  • tensioning means which stretches adjacent foil surfaces along the sides of the formed group
  • the foil made of a plastic material which is shrinkable on heating
  • shrinking means for subjecting the foil to heat of such a temperature that the foil is shrunk
  • the dividing means comprising a distribution wheel rotatably arranged on a vertical axle and protruding partly into the conveyor track with the transverse distance between side walls on one side of the wheel from which the containers are fed toward the wheel corresponding to the width of a container and at the other side of the wheel exceeding the width of a container but less than twice the width of a container,
  • the distribution wheel provided along its periphery with equally spaced recesses to accommodate containers and the spacing being chosen so that every other container is carried on the conveyor track by means of a recess and alternate containers by the periphery of the distribution wheel between successive recesses,
  • a second wheel rotatably arranged on said last-mentioned axle to facilitate feeding of the containers into said following conveyor tracks.
  • a machine for wrapping in a foil a group of containers arranged beside each other so that viewed from above each group substantially forms a rectangle with the containers being fed into the machine in a single row along a conveyor track which has an endless belt serving as its floor and which has side walls, the machine comprising in combination:
