Definitions

  • the invention relates to a stationary oscillating piston press for cardboard waste, paper, film and the like.
  • a press piston arranged to oscillate about a pivot point located below the press channel moves back and forth and with a feed device, which is in temporal relationship to the Press plunger conveys the material to be pressed through a press channel filler opening into the press channel.
  • a known vibrating piston press of this type (CA-PS 627 859) is designed to be mobile and is used to collect straw material lying in swaths on the ground, such as hay or straw, by means of a pickup, to press it into bales and to tie it up. Two consecutive funds are provided to feed the crop from the pickup to the filling opening and to plug the crop into the baling channel.
  • the transducer is first followed by a continuously operating rotary conveyor, which continuously conveys crops into a collecting area.
  • a swiveling packer with fixed, V-shaped stuffing elements is provided in the collecting space and is intended to stuff straw material into the baling channel after each return of the baling piston. The design of this packer is unsuitable for reliable filling of the press channel.
  • the crop sticks between the V-shaped tamping elements and can be taken back while the packer is returning. Furthermore, when the stuffing elements are immersed in the baling press channel, the rotary conveyor pushes on the back of the packer, which is pushed into the upper corner of the collecting chamber when the packer returns and remains there.
  • the invention has for its object to eliminate the disadvantages described above and to create a vibrating piston press, which with different materials and in particular also with cardboard waste reliable and good filling guaranteed.
  • the feed device has controlled conveyor tines, which move at different speeds in an approximately kidney-shaped orbit, the path speed of the conveyor tines in the lower half of the orbit directed towards the filling opening being substantially greater than in the upper Half, so that the conveyor tines accelerate into the press channel opening and also emerge accelerated. Due to the kidney-shaped orbit of the conveyor tines, these are only in the conveyor section in engagement with the material to be conveyed, while they are inevitably pulled out of the material on the return section and create space in the feed space for the subsequent material.
  • the higher speed of the conveying tines during conveying results on the one hand in a safe separation between the package to be potted and the subsequent quantity of material and on the other hand an optimal filling of the press channel during the relatively short-term, complete opening of the filling opening by the press piston. Since the delivery tines remain relatively far away when the piston returns and the press channel filler opening is closed, there is no high pre-compression, which, for. B. in cardboard waste would make it difficult to insert the material into the press channel. Pinching between the plunger and the filling opening is avoided. Due to the higher speed of the conveyor tines when pulling back, they are quickly pulled out of the path of movement of the approaching plunger and from the stuffed material, so that a return of material from the press channel is reliably prevented. Even bulky cardboard waste such as paper, cardboard or the like is reliably fed into the press channel.
  • the further embodiment of the invention provides that the conveyor tines are controlled via a crank swing gear with a non-uniformly rotating crank, the crank drive being effected via a roller gear which has elliptical or eccentric gear wheels. This will make one simple, trouble-free feed device created, the drive can be carried out with uniform rotation, that is to say mechanically coupled with other uniformly rotating elements.
  • the ram speed during the return stroke is greater than during the press stroke. This results in a shorter time for the ram return and thus a longer opening time of the filling opening, which has proven to be particularly advantageous in connection with the fast delivery tines.
  • the plunger slowly moves up during the press stroke and, in combination with the conveyor tines that quickly dodge upwards, enables the path of the conveyor tines to extend into its path of movement.
  • a space-saving embodiment of the oscillating piston press is achieved if the arrangement of the crank swing gear is selected so that the coupling rod is under tensile stress during the working stroke of the press piston.
  • the vibrating piston press has a stationary press chamber housing, the feed opening being preceded by a feed chamber, which has the feed device in the upper area, while the lower area consists of an approximately horizontal feed table, which is on the bottom end of the filler opening opens into the baling channel.
  • the loading area can be loaded by hand or by any other independent means.
  • a press room housing 1 is built on support feet 2 and has a rectilinear baling channel section 3 and an arching baling channel section 4, in which a baling piston 6, which is pivotably mounted about the pivot point 5, moves back and forth between a lower position 7 drawn in full lines and an upper position 8 drawn in broken lines.
  • the upper wall 9 of the press channel section 4 has a filling opening 10, which is preceded by a feed space 11.
  • the plunger 6 completely releases the filling opening 10 in its lower position 7.
  • the feed space 11 is formed by a feed table 12, which extends between two side walls 13 and opens into it at a distance above the lower position 7 of the plunger 6 approximately at right angles to the baling section 4.
  • a conveyor belt 15 rotating uniformly in the direction of arrow 14 is arranged in the feed table 12. The transition from the conveyor belt 15 to the filling opening 10 takes place through a fixed platform 16, which ends shortly before the movement path 18 of the plunger 6 with a double fold 17 and forms the lower edge of the filling opening 10.
  • the conveyor tines 20 are rotatable on the one hand by means of a pin 21 connected to a crank 22 and on the other hand attached to the coupling 23 of a crank linkage so that the conveyor tine tips 24 move around the stationary pivot point 25 in an approximately kidney-shaped orbit 26 through the feed space 11 when the crank 22 rotates.
  • the orbit 26 is divided into a conveyor section 27, in which the conveyor tines 20 are in a good-promoting engagement and move over the platform 16 into the baling channel section 4, and in a return section 28, in which the conveyor tines 20 move after being extracted from the material move back to the position of engagement.
  • an elliptical gear 30 is fastened eccentrically to the fulcrum 25 and cooperates with an also elliptical gear 31.
  • the gear 31 is connected in a rotationally fixed manner via a shaft 32 to a gear 33 which is coaxial with the shaft 32 and is driven by the drive motor 35 via a chain drive 34.
  • the transmission ratio of the elliptical gears 30, 31 is variable between 1: 0.5 to 1: 2 as maximum values.
  • the arrangement is such that the largest radius of the driving gear 31 faces the smallest radius of the driven gear 30 when the conveyor tines 20 are just before the filling opening 10 (position 180 degrees), or the plunger 6 in its lower position 7 is. As a result, the conveying tines 20 come into and out of the filling area at their greatest or approximately greatest speed.
  • the plunger 6 is driven via a crank linkage, the crank pivot 36 of which is offset from the pivot 5 of the link 37 by the eccentricity e, so that the crank angle identified by the number 38 is greater than 180 degrees during the press stroke.
  • the coupling rod 39 is loaded when the plunger 6 moves from its lower position 7 upwards to train.
  • the crank 40 is driven via a chain drive 41 by the drive motor 35 in a gear ratio of 1: 1 to the shaft 32.
  • the markings of the orbit 26 each indicate the associated position of the conveyor tines 20 after a 30 degree crank rotation in the direction of rotation indicated by arrow 42.
  • the movements move between 150 degrees and 240 degrees Conveyor tines 20 are particularly fast, while initially only very much at 30 degrees move slowly.
  • the cardboard waste to be pressed is pushed into the feed space 11 with the machine running in the direction of arrow 42.
  • the conveyor belt 15 driven in the direction of the arrow 14 guides the material onto the platform 16.
  • the downward-moving conveyor tines 20 driven in the direction of the arrow 44 bend and fold the material and, after reaching their 150 degree position, stuff it up to the 210 degree angle.
  • the conveyor tines 20 then pull back out of the press channel 4 and from the material quickly along the return section 28.
