Definitions

  • the invention relates to a device for unpacking products arranged in rectangular holders of cuttable material such as butter or like fats arranged in cardboard boxes.
  • the invention has for its object to provide a device wherewith such products, which to date are unpacked manually, can be unpacked mechanically such that the production capacity is greatly increased whereby the feed of products can be adapted to automatic processes for further processing.
  • the heavy manual labour involved in such unpacking can therein be avoided.
  • the device according to the invention is distin­guished by a frame, a conveyor belt carried by that frame with transporting means for conveying a holder at a time past a cutting station for cutting through a wall part of the holder and a heating station for softening adhesive at points of adhesion on the holder.
  • the device If the products are also packed in a lining present in the carton then it is recommended also to embody the device with two cutting stations for arranging cuts in the standing wall parts of the lining wherein the device is further provi­ded with a removal station for removing the two parts of the lining.
  • the conveyor belt is divided at least between the second and third cutting station into two parts which mutually enclose a right angle.
  • the surface area required for the device is also considerably limited.
  • resisting means consist for example of hook-­like members displaying a speed varying from that of the transport movement of the products.
  • the device shown in the figures consists of a frame 1 which is substantially constructed from a number of standing and lying profiles. Formed on the top of the frame 1 is a conveyor belt 2 upon which the products P which are packed in a packaging V are moved forward in the direction of the arrow P1.
  • a number of carriers 3 can be moved forwards in the direction of the arrow P1 along the first part of the conveyor belt 2 at bottom left in fig. 1, which carriers are attached at either end to a number of endless elements 4 which are trained around reversing rolls 5 and which are set into rota­tion by unshown means.
  • the interval between the carriers is such that a determined distance is maintained between the products P.
  • a number of processing stations are disposed along the conveyor belt.
  • a cutting station which consists of a portal of posts 7 and a girder 8 along which a cutting device 9 can be moved up and downward.
  • the cutting device is provided with a horizontal beam 10, see fig. 2, which is fixed at either end to a car­riage 11 provided with guide rolls 12 which are slidable in up and downward direction along the two posts 7.
  • the beam 10 is provided in the middle with a bracket 13 which is coupled to the bottom end of the piston rod 14.
  • the piston rod 14 is part of a cylinder 15 arranged on the girder 8 and which can be energized such that the horizontal beam 10 with cutting station fixed thereto can be moved in up and downward direction.
  • the cutting member consists of a guiding 16 lying behind the horizontal beam 10 and along which a knife 17 can be moved back and forth transversely of the transport direc­tion P1.
  • the driving of the knife 17 in the guiding 16 take place in random manner and is not further elucidated.
  • An example can be a cylinder with cylinder rod lying in the guiding 16 which is energized by an air medium or the like.
  • a packet P is observed by sensors 18 on either side of the conveyor belt 2 as well as a sensor 19 which is ar­ranged in front of the bracket 13 above the conveyor belt 2.
  • the sensors or feelers 18, 19 serve to determine whether the packet complies with the conditions of size and position for further processing.
  • a light-sensitive element 20 is radiated with a light-transmitter 21 on either side of the conveyor belt 2 for observing a packet P.
  • the beam 10 is moved downward onto the packet P for opening and the knife 17 is also moved again by the cylinder 15 in order to cut into a corner of the packet P whereby the join of the upper and standing rear wall of the packet P is broken.
  • an adjustable support not shown in the drawing, which rests on the packet.
  • the heating device consists of a blower 22 for feeding a hot air flow in the direction of tape T present on the sides of the box. By heating the tape T the adhesive thereon will soften and the join between the two standing half wall parts of the packet will be broken.
  • a sensor wheel 23 which is provided with holes 24 and which co­acts with a sensor 25 which observes whether the wheel, which has a knurled periphery 26, is set in rotation by the upper side of the packet P.
  • the sensor 25 is constantly reset which generates a signal for setting into operation the burners 22.
  • the heating device 42 is rendered inoperative to avoid the danger of fire.
  • the packet here consisting of a folded cardboard box
  • the packet is cut loose, whereby it can be unfolded in the direction of transport, see on the right in fig. 1 and fig. 3.
  • the product in the packaging is therefore released and lies on the bottom portion of the packaging still situated on the conveyor belt 2.
  • a cross beam 43 which is provided with a carriage 26 which is connected to a pressure member 27, see also fig. 3.
  • the conveyor belt 2 has here a second part 2′ which lies at a right angle relative to the first part at the bottom of fig. 1.
  • the formerly standing side of the packet P becomes the underside on the second part of the conveyor belt 2′ and can subsequent­ly be carried away for further processing.
  • the packaging V can finally be removed at the end of the first part of the conveyor belt 2 either through being pushed up by following packets or by hand.
  • the embodiment shown of the unpacking device accord­ing to the invention is subsequently provided with a second part which is occupied with the removal of the lining arranged around the product.
  • This lining is of plastic material, for example polypropene, and is entirely closed on all sides by welding. This is with respect to the prevention of leakage if the product, for example butter, melts because of increase in temperature.
  • the cutting stations are shown in fig. 4.
  • the frame has several posts which protrude above the conveyor belt 2′ and which are provided at a determined height with cutting members 30 which extend parallel to the conveyor belt 2 and this on either side thereof.
  • movable threshold 27′ in the direction of the arrow P4 the packet will be cut into on opposite sides by means of the knives 30.
  • the packet is placed in the correct position relative to the belt 2 by guiding rods 31 extending at the correct height above the conveyor belt 2.
  • Each knife is arranged on a pivotal carrier 32 which can be placed into or out of the active position by means of a cylinder 33 such that the lining can be cut in the correct manner.
  • a pivotal carrier 32 which can be placed into or out of the active position by means of a cylinder 33 such that the lining can be cut in the correct manner.
  • Use is made herein of air pressure which controls the force exerted by the knives. This pressure is adjustable to adapt the knife force to the product.
  • each packet P can be cut into along the four standing sides whereby the lining arranged therearound is divided into an upper and lower por­tion V′ and V ⁇ respectively.
  • Transport along the belt part 2′ takes place with the movable threshold 27′ while transport along belt part 2 ⁇ takes place with transport members 35 which consist of down­ward hanging strips which are attached pivotally to an upper frame 36.
  • This upper frame 36 consists of cross beams which are provided at either end with roller bodies 37 which are guidable in a longitudinal rail 38 on either side and above the conveyor belt 2.
  • the cross beams 44 are mutually connected by a longitudinal beam 39.
  • the strips 35 are connected to the cross beams 44 via a hinge 40 which functions such that the strips can fold upwards from a downward-pointing position in the direction of the arrow P8 to a horizontal position.
  • the longitudinal beam 39 is driven by a cylinder 41, see the top of fig. 1, which sets the longitudinal beam into reciprocal motion according to the arrow P5.
  • the packet initially passes a member with which the outside of the packet is deformed.
  • This member can for example be formed by infrared radiating means.
  • sprays are arranged with which heated water is sprayed on the lining. This furthers the release of the lining.
  • the conveyor belt 2 ⁇ is provided at its end with resisting members 50 located at the upper and lower sides of the conveyor belt 2 ⁇ .
  • These resisting members are hook-like, see fig. 6, and consist of arms 53 rotatable relative to the support 51 and the point of rotation 52 respectively, which arms can be respectively turned downward by means of separate­ ly controllable cylinders 54 or turned upward into the con­veyor belt 2 by a draw spring 55.
  • the hooks 50 grip the lining portions V′ and V ⁇ respectively and as the packet is carried through by means of the strips 35 the lining is pulled from the product P. Transport of the product P takes place over a downward pivotable hatch part of the conveyor belt 2 which is designated by 56.
  • the product arrives in the position accord­ing to the dashed line P′ on the right in fig. 6 and can be carried away by an end conveyor 57 which can take a random form.
