Definitions

  • This invention relates to a machine for wrapping pallet loads with a film which holds the load together during loading and during transportation. More specifically, it is a film wrapping machine that wraps around the load when the pallet is stationary.
  • the transport of cargo from pallets is an essential part of commercial transport.
  • the pallet loads often contain products that cannot be stacked so stably that there is sufficient inherent stability for transport. It is often desirable, depending on the order to be carried out, to transport pallet loads consisting of products of different sizes and shapes. In such and numerous other cases, methods have proven to be advantageous in wrapping the pallet loads with a film, such as, for example, plastic film, fabric or plastic nets, which firmly enclose the packaged goods and hold them together in the event of impacts and impacts.
  • the aim of this invention is to provide a novel and simple machine which is economical in terms of construction, installation and operation and which is suitable for wrapping pallet loads, a roll-off device with stretch film being guided around the packaged goods and being raised and lowered in the process, so that the entire load is closed without loss of film wrap around.
  • This invention relates on the one hand to a film wrapping machine for wrapping pallet loads or the like, which consists of the following parts: a support arm for horizontal attachment to a vertical fastening surface above the pallet load, a boom which is rotatable at one end on the carrier arm at the one of the fastening surface a side, is mounted on the other end of the cantilever arm, from which the film is unwound, and a drive mechanism, which ensures that the cantilever arm rotates around the load, thereby unwinding the film from the roll on the unwinding device, and is wrapped around the packaged goods.
  • This invention relates to a film wrapping machine for wrapping pallet loads or the like with stretch film, consisting of the following parts: a carrier arm arranged next to the pallet load, a cantilever arm which is rotatably mounted on the carrier arm at one end, and one at the other outer end of the carrier arm Unwinding device attached to the unwinding device for unwinding the stretch film, a drive device which ensures the rotational movement of the cantilever arm over the packaged goods, so that the stretching film is unwound from the unrolling device and wrapped around the pallet load, and a device connected to the unrolling device which ensures that that this during the Rotational movement of the boom about the pallet load between a first and a second stop is moved back and forth, whereby the stretch film is wrapped around the packaged goods within the range of the first and second stops.
  • Figure I shows a pallet load 1 located on pallet 2 in front of the invented machine.
  • the machine comprises a support arm 3, a rotatable arm 4 and the unwinding device 5.
  • the support arm 3 is screwed to the wall 6 using plate 7 and screws 8.
  • bracket arm 3 is shown wall mounted here, it can also be attached to a vertical device, such as a vertical I-beam (not shown) attached to a portable, C-shaped device that rests on the floor. With such an arrangement, the pallet would be moved onto the C-shaped device, whereby its stability during the winding process is ensured by the weight of the load.
  • bracket 3 it is preferable to support bracket 3 with brackets or screw it to a vertical wall, as shown in Figure I, because this construction requires the least amount of space while providing a sufficiently rigid attachment to accommodate the forces generated by the machine during the winding process is.
  • the support beam 3 of the present construction is made of sheet steel and consists of an upper plate 9, lower plate 10, end plate 11 and two mutually opposite side plates 12, which results in a housing or cavity between said plates 9, 10, 11 and 12.
  • a motor 13 is mounted on the support arm 3.
  • a drive mechanism is located in the support arm 3.
  • a pulley 15 and 16, respectively, are located on a shaft on motor 13 and transmission 14, and are connected to one another by drive belt 17.
  • the cantilever arm 4 is also made of sheet steel and consists of an upper plate 18, lower plate 19, end plates 20 and the opposite side plates 21, which results in a rectangular housing.
  • the cantilever arm 4 contains a shaft 22.
  • One end of the shaft 22 is fixedly connected to the cantilever arm 4, the other end of the shaft 22 is rotatably mounted in the support arm 3.
  • gear 14 there is an opening 23 in which the other end of shaft 22 is arranged detachably.
  • Cantilever arm 4 contains motor 24 and operations 25. On gear 25 there is a pulley 26 connected to a rotating shaft and a sprocket 28 connected to a shaft, which are arranged at right angles to one another and are connected to one another via gearwheels (not shown), see above that the horizontal power transmission is converted in a manner to be explained in more detail within a cantilever arm 4 into a vertical movement toward the rolling device 5.
  • gear 25 there is a pulley 26 connected to a rotating shaft and a sprocket 28 connected to a shaft, which are arranged at right angles to one another and are connected to one another via gearwheels (not shown), see above that the horizontal power transmission is converted in a manner to be explained in more detail within a cantilever arm 4 into a vertical movement toward the rolling device 5.
  • Beam 30 is also made of sheet steel and consists of an upper plate 31, front plate 33, rear plate 34 and side plates 35 and 36, so that there is a rectangular housing.
  • the top plate 31 is provided with a number of holes 37 in which screws (not shown) can be attached for the fixed attachment of beams 30 to the extension arm 4.
  • a sprocket is located on the beam 30 in the area facing away from the cantilever arm 4.
  • the chain wheels 28 and 40 are connected to one another via the drive chain 39.
  • FIG. II there is a vertical slot 41 in the front plate 33 and two also vertical, protruding flanges 42 over its entire length.
  • the flanges 42 serve to guide a vertically displaceable holder with a slide 43 for handling one stretchable film 45, such as plastic film or the like over the pallet load 1 in a manner to be explained in detail later.
  • Holder with slide 43 has a vertical plate 44 on which guide profiles 46 are provided for receiving the flanges 42 of beams 30 so that they can be displaced in the vertical direction.
  • the vertical plate 44 is provided with holes 47 in which the screws 48 are to be attached, which are used by means of the holder 49 and the fastening screws 50 for fastening to the chain 39 through slot 41, as can best be seen in FIG. II.
  • Upper plate 51 and lower plate 52 are also located on a holder with slide 43.
  • the film roll holding plate 53 for receiving the film roll 54 can be attached to the lower plate 52.
  • Roller 54 is pushed axially onto roller shaft 55 and then secured with wing nut 56.
  • the roller shaft 55 is also provided with a tension spring 57 which, in combination with the wing nut 56, offers the user the possibility of adjusting the tension of the plastic film 45 during the winding process.
  • a tension spring 57 which, in combination with the wing nut 56, offers the user the possibility of adjusting the tension of the plastic film 45 during the winding process.
  • Increased tension allows the user of the machine to wrap the film 45 tighter around the pallet load 54 as it rotates. If the roller 54 consists of stretch film, such as the plastic film 45, this stretch film is stretched by the increased tension, which contributes to a firmer cohesion of the pallet load.
  • Holder with slide 43 is also equipped with the guide rollers 58 and 59, which serve to guide film 45 around the pallet load 1.
  • a pallet load 1 is placed with a pallet truck under the machine in such a way that it is located as centrally as possible under shaft 22.
  • the film start 45 is then attached to a point of the pallet load 1.
  • Motor 13 is then connected via a suitable electrical control device (not shown) and switched on, whereby boom arm 4 rotates around shaft 22 and thus over and around pallet load 1.
  • the length of the cantilever arm 4 is less than the horizontal distance between the shaft 22 and the wall 6, so that it is not touched by the cantilever arm 4.
  • Motor 24 can also be switched on by means of a suitable electrical control device (not shown) in order to move the holder with slide 43 vertically along the packaged goods during the rotation of cantilever arm 4 around the pallet load 1, in order to offset the film 45 vertically around the pallet load 1 to wrap.
  • a suitable electrical control device not shown
  • the holder with carriage 43 is at the first or lowest stop at the bottom when the machine is switched off or put into operation.
  • the motor 24 is switched on, as a result of which the chain 39 lowers or raises the film carriage 43 in the vertical direction, as a result of which the film 45 is wound spirally around the packaged goods during the rotation of the cantilever arm 4 around the pallet load 1.
  • the upper or second stop at the top for the lifting movement of holder with slide 43 is formed by the uppermost point of slot 41.
  • the upper stroke limitation of the holder with the slide 43 can also be regulated by the actuation of the motor 24.
  • the holder with slide 43 can also be equipped with a light barrier 60 with a suitable electrical control device (not shown) which, during the vertical movement of holder with slide 43, emits a light beam in the direction of the pallet load 1, which returns from the load to device 60 is thrown back.
  • a suitable electrical control device not shown
  • the motor 24 can also be equipped with an electrical control device (not shown) that allows the holder with the slide 43 to be moved downwards from the upper position up to the lower position down.
  • the outer ends of beam 30 and cantilever arm 4 can also be equipped with light barriers 61 and 62, respectively. As long as the beam of emitted and reflected light is not interrupted, cantilever arm 4 rotates around the pallet loads 1 after motor 13 has been switched on. If there is an obstacle on the circular path of the machine, the light beam is interrupted and the rotating movement of cantilever arm 4 is automatically stopped . This device is used to protect the machine against accidental damage.
  • the speed of the cantilever arm 4 and the lifting speed of the holder with slide 43 can be controlled by means of appropriate control devices.
  • the user can wrap pallet loads of different heights and different formats using film rolls 45 of the same size.
