Definitions

  • a beater device for use during or after the filling of sacks which are supported at their tops from a filling device in a manner permitting the sack to hang downwardly comprises a beater plate which is supported in an oblique position on resilient bearings.
  • the rubber bushing is carried at the end of a rod which is operated by a crank or eccentric to impart a to and fro beating movement to the shaft piece and to the support plate and heater plate carried thereby.
  • the shaft piece is held for swinging back and forth movement above a resiliently supported foundation on a pivot link which is connected to each end of the shaft piece through resilient bushings or bearings.
  • This invention relates in general to sack or bag filling devices, and in particular to a new and useful device for beating a sack as it is being filled, or after it has been filled with bulk materials.
  • the present invention is particularly applicable for the beating during or after filling of sacks or bags which are to be filled with heavy bulk material and which, for example, will weight more than kg. after filling.
  • the present invention is an improvement over prior art devices of this nature, particularly in respect to the resilient mounting for the beater plate and beater mechanism.
  • Prior to the present invention there have been devices such as an impact device in which the rotational axis of the beating axis is arranged above the center of gravity of the sack which has the disadvantage that it is effective only over the lower portion of the sack.
  • Other devices are known which engage the upper portion of the sack but have the disadvantage that they subject the sack material to impermissible high stresses at the mounting area of the sack body.
  • such devices usually require that the pusher member or bearting element must be arranged so that it may glide along the sack and therefore must be constructed with roller glide members.
  • Such devices are expensive and are subject to rapid wear.
  • a sack beating device which includes a beating plate which is adapted to be arranged obliquely to the sack in order to beat it uniformly over its entire length and without the disadvantages of the prior art construction.
  • the beating plate is mounted in a resilient manner relative to its guiding mechanism. Since the plate is thus not subjected to forced angular changes, the plate can adapt itself to the inclination of the sack to be beaten.
  • the resilient mounting is such that the rotational or pivotal axes for the swinging support element can be arranged directly in the vicinity of the base plate or supporting plate. This has the advantage that no additional space above the upper end of the impact plate is required for constructional elements.
  • a feature of the construction is that the resilient mounting is such that the base and the building support will be subjected to very insignificant shock action.
  • the arrangement further provides means for mounting the motor for driving the beater such that it will be independently supported and protected from any shock.
  • an object of the invention to provide an improved beater construction for bags and sacks which includes means for resiliently mounting the mechanism for effecting a beating action by an oblique plate onto a sack to be filled.
  • a further object of the invention is to provide a heater device which includes a heavy mounting support element which is supported above a building or foundation floor on spaced resilient supporting elements and which carries a double linkage actuating mechanism for moving a beating plate backwardly and forwardly against the side of a sack during the filling thereof and which further includes means for resiliently transmitting the beating force through the associated linkage to the supporting foundation.
  • a further object of the invention is to provide a heating device which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a side elevational view of a heating device for sacks constructed in accordance with the invention
  • FIG. 2 is a top plan view of the beating mechanism indicated in FIG. 1; n
  • FIG. 3 is a section taken along the lines III-III of FIG. 1;
  • FIG. 4 is a view similar to FIG. 3 of another embodiment of the invention.
  • FIG. 5 is a transverse sectional view of another embodiment of beater construction.
  • FIGS. 1 to 3 the invention embodied therein in FIGS. 1 to 3 comprises a flat base plate 1 which is supported above a flat base frame 45 on a building floor 46 by cross members or resilient support members 44, 44 which permit the resilient swinging movement of the frame member 1 relative to the base frame 45.
  • Heavy counter-balancing means or a support casing 24 is formed on one edge of the base plate 1 and is made of a heavy material, for example concrete, to weigh it down.
  • the casing 24 includes an oblique face 24a provided at its upper end with spaced bearing support members 25, 25 which rotationally support end pins or shaft elements 3 and 4, respectively, which are eccentrically connected to a central shaft or shaft membet 5.
  • an actuating rod 6 is rotatably mounted on the shaft 5 through a bearing portion 7.
  • the outer end of the rod 6 is secured to a shaft piece 8 (see FIG. 3) by resilient connecting means which includes a rubber bushing 10 having a metal in ner sleeve 27 and outer sleeve 28 separated by a rubber element 10a.
  • the outer ends of the shaft piece 8 are pivotally supported by respective link members 11, 11 through resilient bushings 30 formed by spaced sleeves 31 and 32 in a central resilient or elastic member 30a (FIG. 3).
  • a beater impact plate 9 is secured to spaced support plates 34 and 34a which are held in position around each end of the elastic bushing 10 by means of spacer sleeve members 37 and 37' which are disposed interiorly of the respective outer bushings 31], 30.
  • the support plate 34 is secured in an adjusted position by means of screws or bolt members 35 which are threaded into end plates 36 which bear against the outer ends of the resilient bushings 30.
  • the links 11 which carry the bushings 30 at their upper ends are pivotally supported on pivot shafts or pivot members 43 by means of rubber bushings generally designated 40 which are of a construction similar to bushings 30.
  • a motor for example a motor having a brake to permit instant stopping thereof
  • the motor 51 drives a pulley 52 to rotate a pulley 54 through a V-belt 53.
  • Rotation of the shaft elements 3 and 4 causes the crank-like movement of the eccentric shaft member 5 and the oscillatory movement of the beater plate 9.
  • the sack 12 which is to K be beaten during the filling operation is mounted on a bell member or securing means 14 at the lower end of a hopper 70.
  • the rod 6 transmits the thrust movement of the plate 9 to the bag or sack 12 upon the eccentric rotation of the member 5.
  • the shaft 8 is guided by means of the links 11 which swing about the pivot point 43 so that the shaft element 8 and the beater plate 9 move essentially backwardly and forwardly to beat the sack 12.
  • the impact of the beater plate 9 against the sack pushes the sack away since it is clamped on its upper end on the bell member 14.
  • the next beating then rapidly follows while the sack 12 is permitted to oscillate backwardly by the action of the gravity. Because of the oblique positioning of the plate 9 the sack is initially positioned outwardly from is natural position in respect to the center of gravity,
  • the above-indicated angular changes of the shaft piece 8 and its rotation relative to the links 11 are absorbed at the rubber bushings 30.
  • the setting or adjustment of the rest position of the beater plate 9 can be effected after loosening screw 35. After the beater plate 9 is properly oriented, the screws are tightened to securely hold the support plates 34 in an adjusted position.
  • the swing metal elements 44 prevent the transmission of shock of the beater arrangement into the building or ground 46. Because of the heavy load of the loading means 24, any tendency for the base plate 1 to receive impact deflections due to the action of the beater plate 9 will be minimized. In this manner the beater arrangement will run smoothly without shocks relative to the building or the ground 46. It has been found to be advantageous to run the device so that 500 to 2000 beatings per minute with strokes of from 5 to 30 mm. may take place. A particularly favorable embodiment of the invention operates with a frequency of 1000 beatings per minute with a stroke of 20 mm.
  • a beater plate 9' is carried on the shaft 8' by means of bushings 57 carried at the outer end of respective space members 60, 60.
  • the embodiment is the same as the other embodiment with the exception of the sleeve members 37a which are relatively short for properly spacing the bushings 57 in respect to the bushings 10' and 30. With this construction the impact plate is capable of adapting itself in orientation to the sack in a still better fashion.
  • elastic support elements 11 are employed which are in the form of elastic tubes or rods which are clamped into the supporting brackets or consoles 42 through the bushings 40, for example.
  • the base plate means includes a base plate member mounted directly on the ground or building 46' generally designated 15.
  • the member 15 includes an upright portion or thrust joint carrier 16 and includes large weight or counterbalancing means 24'.
  • Shaft elements 3' and 4' are mounted for rotation on the counter-balancing means 24' as in the other embodiment in order to provide means for oscillating the rod member 6" which is pivotally connected to the beater member 19.
  • the beater member 19 is of substantially U-shaped configuration and includes inner inwardly turned ends 18 having guide bearings 18' which are guided on rod members 17 held between portions of the carrier 16.
  • Compression springs 20 are arranged on both sides of the bearing guides 18 around the rods 17 and provide means for resiliently balancing the beater member 19 during its beating movement.
  • the springs 20 and 20 may be alternately loaded and unloaded due to the eccentric movement effected by the rotation of the eccentric shaft member 5.
  • the springs 20 are anchored on a safety abutment or formation 21 of the joint carrier 16. They provide the basic support for the beater plate 19. For this reason there must be suflicient play in respect to the guiding member 18' to permit the necessary movement of the beater plate 19 during the operation thereof.
  • the beater plate 19 acts on the sack 12 or 12' over substantially the entire length thereof.
  • a beater device for facilitating the filling of sacks which are supported at their tops in a manner permitting the sack to hang downwardly and swing freely, comprising a beater plate, a substantially horizontally disposed rod member, a substantially vertically disposed pivot link, foundation means, means resiliently supporting said pivot link and said rod member for pivotal movement on said foundation means, resilient bushing means pivotally connecting said rod member and said pivot link to said beating plate and for resiliently holding said plate in an adjustable oblique orientation, and means connected to said rod member to oscillate said rod member to move said beating plate, as it is held obliquely, toward and away from said sack to beat the sack as it is being filled.
