Definitions

  • the present patent application relates to an improved automatic packaging machine used to wrap the upper, lateral and lower sides of products with tape.
  • the improved machine of the invention is an evolution of the machine disclosed in patent EP 0939031, on which it is based, with the introduction of innovative solutions with reference to operating means and operations used to unload finished coils of packaging tape and replace them with new coils.
  • This machine comprises two consecutive aligned conveyor belts, the first belt being designed to convey the product to be packed to the wrapping station and the second belt being designed to receive the product from the wrapping station and convey it to the unloading station.
  • the wrapping station is located in intermediate position between the two conveyor belts and comprises a portal-shaped frame, firmly and permanently fixed to the floor, which supports a series of pairs of wrapping tape coils with different width, one after the other, according to the travel direction of the product to be packed.
  • Each wrapping tape is wrapped around two coils, the upper coil being designed to remain always above the product and the lower coil being designed to be transferred when necessary below the product, and more precisely below the travel plane of the product on the first conveyor belt.
  • each wrapping tape is supported by its own shaft, while the lower coil of each wrapping tape is supported by a shaft capable of making alternate vertical travels, thanks to the fact that its ending pins are engaged with two bushings, respectively inserted and sliding along two guide rods, at the two ends of the frame.
  • Bushings are driven in alternate vertical travels by a motorized chain drive, in such a way that the lower coil of each tape is transferred from the raised position under the fixed coil to the lowered working position under the first conveyor belt designed to convey to the product to be packed to the wrapping station.
  • the first conveyor belt is of telescopic type and moves backwards to allow the coil coming down from the resting position to reach the working position under the first conveyor belt.
  • the front border of the telescopic section of the first conveyor belt is laterally provided with an opposite pair of uprights that support a transversal bar.
  • the transversal bar intercepts and pushes the section of wrapping tape to the wrapping station, while the lower tape coil is momentarily lowered in working position.
  • Loading and unloading require to stop the machine and hold the machine stopped during replacement, while the operator climbs the portal-shaped frame to dismount the shafts that support the upper and lower coil in order to remove the finished coils and replace them with new ones.
  • the purpose of the present invention is to realise an improved packaging machine provided with means to change coils without having to stop the machine, and therefore interrupt packaging, which can be continued at unchanged speed, using new wrapping tape coils.
  • each frame supports a different wrapping tape, wrapped on an overlapped pair of traditional coils, with the lower coil being capable of making vertical travels parallel to its axis in order to be transferred from the raised idle position to the lowered working position under the travel plane of the product to be packaged.
  • the consecutive series of identical portal-shaped frames is located in the space between the first and second conveyor belt above which the telescopic section of the first belt makes its alternate travels.
  • Each portal-shaped frame is provided with ground sliding means in order to be laterally extracted from the series of portal-shaped frames according to a direction orthogonal to the travel direction of the product, it being evident that extraction is only possible after retracting the telescopic section of the first conveyor belt.
  • the portal-shaped frame can be laterally extracted to free the space necessary to extend the telescopic section of the first conveyor belt completely, in order to restore the continuous travelling path of the product between the first and the second belt.
  • the improved machine of the invention comprises a consecutive aligned pair of conveyor belts (1 and 2) and a wrapping station (3) between the first (1) and the second (2) conveyor belt.
  • the first conveyor belt (1) has a telescopic section (1 a) that in forward position is parallel to the second belt (2) in a coplanar way, while in backward position uncovers a large compartment (4) below the travel plane of the product (P).
  • the front border of the telescopic section (1a) of the first conveyor belt (1) is laterally provided with an opposite pair of uprights (1 b) that support a transversal bar (1 c).
  • the telescopic bar (1 c) intercepts and pushes the section of wrapping tape (N) to the wrapping station (3), while the lower coil (10) is momentarily lowered in working position.
  • the wrapping station (3) is transversally enclosed by two fixed portals (5 and 6) that extend astride the ending section of the first conveyor (1) and the initial section of the second conveyor (2), respectively acting as support structure for the frames of the said conveyor belts (1 and 2).
  • the fixed portals (5 and 6) are stiffened by means of corresponding crosspieces (T) connecting their bases.
  • the empty space between the two fixed portals (5 and 6) is occupied by a consecutive series of identical portal-shaped frames (7) that extend transversally astride the space in which the telescopic section (1a) of the conveyor belt (1) operates.
  • Each frame (7) supports a different wrapping tape (N) wrapped on a pair of coils, the upper coil (8) resting on a parallel pair of unwrapping rollers (9) and the lower coil (10) equally resting on a parallel pair of rollers (11).
  • the two pairs of parallel rollers (9 and 11) transversally extend between corresponding opposite pairs of upper (9a) and lower (11 a) carriages that slide vertically along the lateral columns (7a) of the portal-shaped frames (7).
  • the two lower carriages (11 a) are driven in alternate vertical travels by a driving chain (12) of a gear assembly, whose driving geared motor (13) is located in external position at the base of one column (7a).
  • each lower coil (10) can be automatically transferred from the raised idle position (PS) to the lowered working position (PA), in which it rests inside the compartment (4) under the telescopic section (1 a) of the first conveyor belt (1), as shown in fig. 1 with reference to the lower coil (10) in first position along the travelling direction of the tape (1).
  • numeral (14) indicates the geared motor designed to drag into rotation the parallel pair of unwrapping rollers (9) used to unwrap the upper coil (8) of each overlapped pair of coils (8 and 10).
  • Each portal-shaped frame (7) is provided with ground sliding means, i.e. wheels (7b) in this case, to translate laterally according to a direction orthogonal to the travel direction of the product on the conveyor belts (1 and 2), it being evident that translation is only possible after retracting the telescopic section (1 a) of the first conveyor belt (1).
  • ground sliding means i.e. wheels (7b) in this case
  • the frame (7) is translated laterally only to extract the frame (7) from the wrapping station (3) to change the coils (8 and 10) or perform other maintenance or repair operations on the components of the frame (7).
  • each frame (7) can be performed for a distance sufficient to extract the frame (7) from the wrapping station (3) completely, it appears evident that until the frame (7) is parked next to the wrapping station (3), packaging can continue with unchanged speed and method, using the wrapping tapes (N) available on the other portal-shaped frames (7), that is to say the frames (7) in working position.
  • the operator (A) can easily intervene on coils (8 and 10) of the laterally extracted frame (7), after lowering the coils (8 and 10) to the ground, using the support carriages (9a and 11a) that slide along the columns (7a); the operator simply needs to actuate the jack (9b) to retract the stopping pin of the upper carriage (9a), which is supported by the lower carriage (11a).
  • the operator can actuate the geared motor (13) to make the driving chain (12) drag the lower carriage (11a) to the lowered position (PA), together with the upper carriage (9a) that rests on the lower carriage (11 a).
  • Return rollers (15) extend transversally between columns (7a) of each frame (7) and are supported by the opposite pair of upper carriages (9a), used to partially wind up the section of tape (N) coming from the upper coil (8) and going to the lower coil (10).
  • numeral (16) indicates the device used to cut and seal the wrapping tape once the product is completely wrapped.
  • the device (16) of known type is actuated by a geared motor (17) and mounted on the fixed portal (6) with the possibility of making alternate vertical travels.
