A device for unpacking products (P) arranged in rectangular holders of cuttable material such as butter or like fats arranged in cardboard boxes (P), said device comprising a frame (1), a conveyor belt (2) carried by that frame with transporting means for conveying a holder at a time past a cutting station (7, 8, 9) for cutting through a wall part of the holder, a heating station (42) for softening adhesive at points of adhesion on the holder, as well at least two further cutting stations for arranging cuts in the standing wall parts of a lining in said holder and a removal station for removing the two parts of the lining, in order to considerably increasing the unpacking capacity, whereby the feed of products can be adapted to automatic processes for further processing the content of the holder.
Description
- 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.
- As a result of the cutting station and the heating members, cardboard boxes for example which are glued at various locations or held together by tape can be unpacked in simple manner whereby the production rate can be considerably increased.
- 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.
- In a particularly simple embodiment of the device according to the invention the conveyor belt is divided at least between the second and third cutting station into two parts which mutually enclose a right angle. Not only is the arranging of the cuts in the wall parts of the lining considerably simplified herewith, the surface area required for the device is also considerably limited.
- The removal of the lining parts takes place preferably with resisting means which consist for example of hook-like members displaying a speed varying from that of the transport movement of the products.
- Above-mentioned and other features of the invention will be further elucidated in the figure description hereinbelow of an embodiment. In the drawing:
- fig. 1 shows a perspective top view of the device according to the invention,
- fig. 2 shows a perspective bottom view of the device along the arrow II in fig. 1,
- fig. 3 shows a perspective top view of a part of the device of fig. l along the arrow III,
- fig. 4 is a perspective top view of the device of fig. 1 along the arrow IV,
- fig. 5 shows a perspective top view of the device from fig. 1 along the arrow V,
- fig. 6 shows a standing section of a part of the device from fig. 5 along the arrows VI.
- 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 theconveyor belt 2 at bottom left in fig. 1, which carriers are attached at either end to a number ofendless elements 4 which are trained around reversingrolls 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. Thus arranged at 6 is 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. To this end the cutting device is provided with a horizontal beam 10, see fig. 2, which is fixed at either end to acarriage 11 provided withguide 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 thepiston rod 14. Thepiston rod 14 is part of acylinder 15 arranged on thegirder 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 theknife 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 theconveyor belt 2 as well as asensor 19 which is arranged in front of thebracket 13 above theconveyor belt 2. The sensors orfeelers transmitter 21 on either side of theconveyor belt 2 for observing a packet P. When a packet P is present the packet P is stopped by stopping the conveyor means 3, the beam 10 is moved downward onto the packet P for opening and theknife 17 is also moved again by thecylinder 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. Arranged under the beam 10 is an adjustable support, not shown in the drawing, which rests on the packet. - Behind the cutting device 9 is arranged a
heating device 42. The heating device consists of ablower 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. - At the top of the
heating device 42 is arranged asensor wheel 23 which is provided withholes 24 and which coacts with asensor 25 which observes whether the wheel, which has aknurled periphery 26, is set in rotation by the upper side of the packet P. When thewheel 23 rotates thesensor 25 is constantly reset which generates a signal for setting into operation theburners 22. As soon as thewheel 23 stops moving because of the stopping of theconveyor members 3 theheating device 42 is rendered inoperative to avoid the danger of fire. - When it passes through both the cutting station 9 and the
heating device 42 the packet, here consisting of a folded cardboard box, 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 theconveyor belt 2. - Located at the end of the first part of the
conveyor belt 2 at top right in fig. 1 is across beam 43 which is provided with acarriage 26 which is connected to apressure member 27, see also fig. 3. Theconveyor belt 2 has here asecond part 2′ which lies at a right angle relative to the first part at the bottom of fig. 1. By energizing a cylinder acting upon thecarriage 26 thepressure member 27, which grips on the top lengthwise ribs of the packet P, is moved in the direction of the arrow P2 whereby the packet is shifted to the edge of the first part of theconveyor belt 2. Situated along the edge is athreshold 27′ which prevents sliding of the packet P so that as thepressure member 27 moves through the packet is tilted in the direction of the arrow P3. The formerly standing side of the packet P becomes the underside on the second part of theconveyor 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 theconveyor 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 cuttingmembers 30 which extend parallel to theconveyor belt 2 and this on either side thereof. When the packet P is transported by means of the, in this case,movable threshold 27′ in the direction of the arrow P4 the packet will be cut into on opposite sides by means of theknives 30. The packet is placed in the correct position relative to thebelt 2 by guidingrods 31 extending at the correct height above theconveyor 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 acylinder 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. - Because the
conveyor belt 2 passes through a right angle between the first cutting station, below in fig. 4, and the second cutting station, above in fig. 4, and transfers from thebelt part 2′ to thebelt part 2˝, 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 themovable threshold 27′ while transport alongbelt part 2˝ takes place withtransport members 35 which consist of downward hanging strips which are attached pivotally to anupper frame 36. Thisupper frame 36 consists of cross beams which are provided at either end withroller bodies 37 which are guidable in alongitudinal rail 38 on either side and above theconveyor belt 2. Thecross beams 44 are mutually connected by alongitudinal beam 39. Thestrips 35 are connected to thecross beams 44 via ahinge 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 acylinder 41, see the top of fig. 1, which sets the longitudinal beam into reciprocal motion according to the arrow P5. - It will be apparent that as they move to the left in fig. 4 the
strips 35 will carry along a packet each time over theconveyor belt 2˝ while when they move back thestrips 35 can lift up over the top of the packet and slide therealong. Thus brought about is a step-wise forward movement of the packets P along theconveyor belt 2˝. - A description now follows of the device for removing the lining portions V′ and V˝, fig. 5 bottom right. 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. According to a preferred embodiment 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 resistingmembers 50 located at the upper and lower sides of theconveyor belt 2˝. These resisting members are hook-like, see fig. 6, and consist ofarms 53 rotatable relative to thesupport 51 and the point ofrotation 52 respectively, which arms can be respectively turned downward by means of separate lycontrollable cylinders 54 or turned upward into theconveyor belt 2 by adraw spring 55. Thehooks 50 grip the lining portions V′ and V˝ respectively and as the packet is carried through by means of thestrips 35 the lining is pulled from the product P. Transport of the product P takes place over a downward pivotable hatch part of theconveyor 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 anend conveyor 57 which can take a random form. - As soon as the packet P has been transported over the
hatch part 56 this is folded downward by means of thecylinder 60 in the direction of the arrow P6 to the position indicated with a dashed line in fig. 6. The lining portions V′ and V˝ fall downward into adischarge chute 61 and are subsequently crushed by means of a set ofrollers 62 such that the product adhering to the lining is pressed out and the lining portion V can be carried away in the direction of the arrow P7. A conveyor belt can be employed instead of a discharge chute. The adhering product is collected and processed. - From the above description it will be apparent that with the device shown a particularly simple unpacking of products can be effected, whether or not they are packed in a lining.
