Definitions

  • a can press of the type mentioned is known from US Pat. No. 4,248,144. Inside, a fixed and a movable press jaw are arranged opposite each other. On the outside of the fixed press jaw, two rollers, over which a rope runs, are attached. The ropes are with one end on the movable press jaw, which is T-shaped and is guided in grooves, and the other end attached to quarter-circle disks of a movement organ. The two quarter circle discs are held together by a U-shaped connection through which a manual control lever extends. An axis in the center of the circle connects the quarter circle discs and the manual control lever. A can is placed in a feed opening on the bottom of the can press, which is pressed together with the movable press jaw by pulling down the fastening lever and then falls out of a removal opening.
  • This press is mechanically very complex, voluminous and heavy. Pulling the movable press jaw over two ropes and guiding it in the grooves on the side walls of the press enables it to tilt. As a result, the pressure force of the movable press jaw, which is only available evenly for the first upsetting and ultimately the compression of the can, is greatly reduced. If one of the ropes even breaks, the can press may be destroyed or at least damaged.
  • Another can press of the type mentioned is known from DE-U-8 612 401.
  • An insertion chute is placed on a loading opening of a press room of the press.
  • the size of the press room is determined by the height of two fixed and two movable press walls that are perpendicular to it.
  • the press room is closed off by the press room floor.
  • Each press jaw is connected to a plunger or manufactured in one piece and assigned its own actuating lever, which acts on it via a press eccentric.
  • a coil spring is pushed onto the outer section of the plunger, one end of which is supported on the outside of the press chamber and the other end of which is supported on the inside of a plunger head designed as a cap.
  • the press requires two-handed operation, which makes their handling relatively cumbersome and less user-friendly.
  • the mechanical outlay here is also relatively high due to the presence of two press jaws with the associated actuating elements which are required twice in each case.
  • the advantages achieved by the invention consist in particular in that the greater the ratio between the stroke and the diameter of the guide piston, the more successfully tilting in the guide cylinder is avoided.
  • the direct unity of the pressing surfaces with the working piston and cylinder enable a safe and reliable transfer of the pressing force.
  • the essentially eccentrically designed holder enables that stroke and force can be used differently during the entire linear movement according to the needs. So there are two points when squeezing cans, where high forces have to be applied. So when the static is destroyed at the very beginning and secondly when the can is finally pressed together to its minimum volume. The statics of the undamaged can, however, can be very easily compressed by z. B. destroy with your thumb. This bulge forced from the outside is sufficient so that the can can be pressed together in a very simple manner and without great effort.
  • the holder can advantageously be designed as a rope pulley or a chain disk, over the disk cylinder wall of which the rope or the chain can be guided. It is also advantageous if the rope or chain pulley is mounted eccentrically. This makes it possible for the force on the rope or chain to turn out differently when the rope or chain disc rotates during the rotational movement. Due to a varying lever length and the resulting force effect, it is possible to select a small force and a large stroke at the beginning of the movement in order to be able to apply a small stroke but a very high force at the end of the compression.
  • the can press can be designed so that the holder is parabolic or semi-elliptical in shape, whereby the rope or chain is guided over the walls formed by the tangents, and the bearing is arranged outside the main axis.
  • the holder is formed on two eccentric disks arranged in parallel and connected to one another via a retaining bolt.
  • the actuating member In order to be independent of energy sources, it is advantageous for the actuating member to be a manual actuating lever which extends radially from the holder and is firmly connected to the holder. As a result, this device can be used at various points without the need for a power supply.
  • the axis of the bracket and the actuating lever consist in one piece or from a / a substantially right-angled rod or tube, that the bracket is fixed non-rotatably on its axis and that the outer ends of the axis rotatably in two holes or Bearing bushes or in a one-sided bearing in the guide piston.
  • the bearings can also be roller or slide bearings.
  • the actuating member is a motor connected to the holder via a gear. Since the extensive muscle strength is no longer sufficient with larger doses, the use of the motor in a more professional area is appropriate.
  • the articulation of the motor with the aid of a transmission can be found in the prior art. Different types of gearboxes are used, the task of which is to work as a reduction gearbox in order to enable a high level of force to be developed.
  • the can press is designed in such a way that it has two mutually opposite slots running in the longitudinal direction through the lower part of the guide piston and at least one bolt which is fixedly connected to the guide cylinder and through which the slots and the inside of the guide piston have a free cable or chain end is attached substantially centrally in the interior of the guide piston.
  • the can press consists of two inner cylindrical tube pieces, namely a short working piston and a long guide piston, the axis of the holder being mounted on the guide piston connected to the working piston at its end opposite the working piston, and that the can press is two also has tubular outer cylinders, namely a working cylinder and a guide cylinder connected to it, the free rope or chain end being fastened to the guide cylinder.
  • the guide cylinder takes on the role of a piston rod in order to adjust the movement of the guide piston and the working piston. He also carries the attachment point for the corresponding holder, with which the outer cylinder is moved relative to the piston cylinder by means of a cable or chain hoist.
  • the rope or the chain in its further course substantially along the central axis of the piston or the cylinder Deflection roller is present.
  • this deflection roller With the aid of this deflection roller, the diameter of the guide cylinder and the guide piston can be kept very small without the rope or chain being rubbed. Furthermore, the deflection rollers allow the tensile force to act centrally with respect to the guide and working cylinder.
  • the feed opening for a can to be compressed is arranged in the cylinder jacket of the working cylinder and that its height is substantially equal to the height of an unpressed, upright can. It is essential for the compression of the cans that the stroke to be carried out does not exceed certain limits, particularly long cans are difficult to compress with respect to their longitudinal axis. It would be more advantageous to compress them laterally.
  • gravity ensures that after the pressing process, the working cylinder and the working piston return to the original state, in which the working cylinder has the largest volume; however, it may be necessary for a return spring to move the cylinder and piston to their home position after actuation.
  • the piston and cylinder are arranged at an angle or the can press is mounted at an angle, preferably at an angle of 45 °.
  • the can thus falls through the ejection slot into a collecting device located underneath. Due to the inclined position of the can press, gravity is no longer sufficient to return the cylinder and piston to the original position to be loaded. Rather, it is necessary to achieve a restoring force with the aid of a spring.
  • the feed opening has a funnel arranged outside the working cylinder.
  • the can can simply be thrown into the funnel, it is oriented spatially at the end of the funnel and is inserted into the working cylinder in the position required for the compression.
  • a rear wall mounting frame is advantageous for fastening the can press.
  • the illustrated embodiment of the can press 1 essentially consists of a guide piston 2 'connected to a working piston 2 ", which is guided in a guide cylinder 3' which merges into a working cylinder 3". Furthermore, the can press 1 has an actuating element 4, by means of which the pistons 2 'and 2 "and the cylinders 3' and 3" can be moved relative to one another.
  • the guide piston 2 ' merges into the working piston 2 "without an externally visible transition. While the guide piston 2' is laterally delimited by the pipe section 21, the working piston 2" is closed off by the piston head 23.
  • the guide piston 2 ' is surrounded by the likewise tubular guide cylinder 3'.
  • the inner diameter of the guide cylinder 3 'and the outer diameter of the guide piston 2' are chosen so that a jam-free displacement of the guide piston 2 'in the guide cylinder 3' is ensured.
  • the guide cylinder 3 ' merges seamlessly into the working cylinder 3 ", which is closed at its lower end by a base plate 33.
  • the guide piston 2 ' In its lower half, the guide piston 2 'has in its wall 21 two mutually opposite slots 22 and 22' running in the longitudinal direction of the piston. Through these slots 22 and 22 ', a bolt 35 runs transversely through the guide piston 2' and the guide cylinder 3 'and with its outer ends is fixed to the Cylinder jacket 31 of the guide cylinder 3 'is connected.
  • the lower end 47 of a cable 45 preferably a steel cable, is fixed to the bolt 35 approximately in the middle thereof by means of a compression fitting 48.
  • the cable 45 leads upwards through the interior 20 of the guide piston 2 'and, via a deflection roller 25 carried by an axis 26, reaches a cable pulley 41 mounted in the upper part of the guide piston 2'.
  • the other end of the cable 45 is attached to this cable pulley 41 a fixation 46 is set so that there is a positive connection in the pulling direction of the cable 45 between the latter and the pulley 41.
  • the rope pulley 41 is fixed on an axis 42 crossing the upper part of the guide piston 2 ', which in turn is rotatably mounted in two bearing bushes 24 and 24' in the wall 21 of the piston 2 '.
  • At the right end of the axis 42 there is a manual control lever 43 which extends approximately at right angles to the axis 42 and has a handle 44.
  • the working cylinder 3 "has a feed opening 32 through a correspondingly large cutout in the working cylinder jacket, here in the front, is formed. A can can therefore be inserted into the interior 30 of the working cylinder 3 ′′ through this opening 32.
  • an ejection slot 34 is used, which is recessed in the lower part of the working cylinder 3 "in the direct connection to its base plate 33 in the rear part of the working cylinder jacket.
  • FIG. 2a of the drawing shows the can press 1 from FIG. 1 also in longitudinal section, but in a section plane rotated by approximately 90 ° with respect to the section plane of FIG.
  • the front of the press 1 is accordingly on the right in FIG. 2a, while the back of the press 1 is on the left in FIG. 2a.
  • the pistons 2 'and 2 "and the corresponding surrounding cylinders 3' and 3" can be seen again.
  • the actuating member 4 more precisely the actuating lever 43 and the associated pulley 41, can be seen in a side view. From this illustration it is clear that the pulley 41 has a circular shape and is mounted eccentrically, ie outside of its center, rotatable about the axis 42.
  • the rope 45 runs in the basic position of the press 1 shown in FIG. 2a over a relatively small part of the circumference of the rope pulley 41 and is fixedly connected to it by means of the fixation 46.
  • the deflection roller 25 can be seen, which ensures that the cable 45 extends in its further course up to the bolt 35 substantially along the central axis of the guide piston 2 'in its interior.
  • one slot 22 of the two guide slots in the guide piston 2 ' can be seen in the lower part thereof.
  • the bolt 35 which is connected with its outer ends to the guide cylinder 3 ', is located in that in Figure 2a shown state of the press at the lower end of the slot 22, which has the function of a stop here.
  • the piston crown 23 is here in its highest position or the base plate 33 of the working cylinder 3 "is in its lowest position.
  • the height of the working cylinder interior 30 is so great that a tin can 10 to be compressed is in the direction of the movement arrow 52 can be inserted into the interior 30 of the working cylinder 3 ".
  • the ejection slot 34 can also be seen in the lower left part of the cylinder 3, the height of which is selected so that a compressed tin can can be ejected through it, as will be explained with reference to FIG. 2b, which will be described below.
  • the pulley 41 is mounted eccentrically.
  • the eccentricity of the bearing is selected so that the length of the lever arm between the axis 42 and the point of impact of the rope 45 on the rope pulley 41 is greatest at the beginning of the pressing process, as shown in FIG. 2a. This means that when the actuating lever 43 is rotated in the direction of the movement arrow 51 at the beginning of this movement, the movement of the cable 45 is relatively large, but the force exerted is relatively small. This makes sense because first the deformation of the tin can 10 requires a relatively small amount of force.
  • Figure 2b shows the press 1 in its functional state at the end of a pressing process.
  • the guide piston 2 "and the working cylinder 3" are now moved into each other so far that the bottom of the working piston 2 "and the bottom plate 33 of the working cylinder 3" are only a relatively short distance apart.
  • the compressed tin can 11 is only a fraction of the original height of the unpressed tin can 10.
  • the actuating lever 43 serving as the actuating member 4 is now in a substantially horizontal position which is rotated clockwise by an angle of approximately 110 ° with respect to the starting position, as was shown in FIG. 2a.
  • the majority of the rope 45 is now wound onto the rope pulley 41, on which it is fastened by means of the fixation 46.
  • the distance between the axis 42 of the sheave 41 and the point of impact of the rope 45 on the sheave 41 is now significantly smaller than it was at the beginning of the pressing process. This means that the movement of the rope 45 is relatively slow, but that the force exerted is relatively large. This has the advantage that the increased effort required for the final phase of pressing the can 10 or 11 together can be effortlessly applied.
  • the deflection roller 25, which is arranged in the upper part of the piston 2, can also be seen in FIG. 2b.
  • the bolt 35 has now reached the upper end of the slot 22, which in turn forms a stop for the movement of the guide piston 2 'and guide cylinder 3'.
  • the feed opening 32 in the working cylinder 3 is now largely closed by the working piston 2".
  • the compressed tin can 11 can now be ejected through the ejection slot 43 in the direction of the arrow 53.
  • a collecting vessel for example a collecting bin, is expediently arranged behind or below the ejection slot 34.
  • the press 1 When the press 1 is designed with a fixed working piston and guide piston 2 and a working cylinder and guide cylinder 3 which is axially displaceable relative to the latter, the press 1 comes back to its starting position solely by the weight of the cylinders 3 'and 3 " Press 1, in which the working cylinder 3 "is stationary and the working piston 2" together with the guide piston 2 'with the actuator 4 is designed to be displaceable, it is expedient to provide a return spring which brings them into their basic position between the guide cylinder 3 'and the guide piston 2'.
  • Pipe pieces are preferably used as the starting material for the working piston 2 'and the associated guide piston 2 "and the guide cylinder 3', however, four-sided or polygonal pressed sheet metal parts can also be used.
  • the rope pulley 41 can also be designed as a pulley segment, since only one Part of its circumference is required for the actuation of the press 1. In practical tests with a press according to the present innovation, it has been shown that, for example, a tin can with an original height of 115 mm can be compressed to approximately 13-14 mm, ie 1/8 of its original height is.
  • FIGS. 3 and 4 corresponds to the embodiment described above with a few differences.
  • the difference consists in a different design of the working cylinder 3 "and the working piston 2".
  • the working cylinder 3 "and the working piston 2" located therein have a cross section that is rectangular when viewed from above.
  • the working cylinder 3 has two parallel longitudinal sides 36 and 36 'which are delimited at their ends by transverse sides 37 and 37'. While the longitudinal sides 36 and 36 'have approximately the length of a longitudinal long box, the distance between the two transverse sides is 37 and 37 'the diameter of the guide piston 2', which is larger than the diameter of the standard cans.
  • the feed opening 32 is located on one of the transverse sides 37, whereas the ejection slot 34 is arranged on the opposite transverse side 37 '.
  • the base plate 23 of the working piston 2 is designed to be correspondingly wider for this.
  • the working cylinder 3 "and working piston 2" clearly differ from the guiding cylinder 3 'and guiding piston 2'. This was not so clearly seen in the previous embodiment, since the cylinders and the pistons merged into one another without being set apart.
  • the can press is loaded either by inserting a normal can in the upright position or a long can in the lying position into the working cylinder 3 ", which has a bottom plate 33 that is lowered to the maximum.
  • the pressed can 11 takes up a height which is smaller than the height of the ejection slot 34.
  • the working cylinder 3 "and thus the guide cylinder 3 ' is returned to its original position by the force of gravity, in which the interior 20 of the working cylinder 3 "in connection with the guide piston 2" occupies its maximum volume.
  • the compressed can 11 is pushed through the ejection slot 34 and falls into a collecting device (not shown).
  • the cans can also be pressed in long format. Compressing these cans in an upright position is no longer possible because, due to the long stroke, a force required for the compression can no longer be achieved with ease, as is possible with a can press with a relatively small stroke.
  • FIG. 4a A further exemplary embodiment is shown in FIG. 4a.
  • the holder is not designed as a disk but as a semi-elliptical disk 41 ', which is created by a cut along the minor axis through a full ellipse.
  • the fixation 46 is arranged at the intersection of the ellipse line and the main axis.
  • the half-elliptical disk 41 ' is not centered by the axis 42, rather the axis goes through the ellipse edge approximately at the level of the minor axis.
  • the main axis of the semi-elliptical disk 41 ' runs approximately horizontally, in the end position at maximum pressure an essentially vertical position is assumed.
  • the can press 1 is driven by a motor 61.
  • the rope 45 is fastened on the one hand to the cross bolt 35 and on the other hand to a retaining bolt which connects two eccentric discs 62 and 62 'to one another.
  • the two eccentric disks 62 and 62 ' which are arranged in parallel and connected to one another via the retaining bolts 67, rotate about a common eccentric axis 63, which, however, is recessed in the space between the disks.
  • the eccentric axis 63 is rotatably supported in two bearing positions 64 and 64 ', which are arranged on the upper edge of the guide piston 2'.
  • the Eszenterscheche 62 and 62 ' are connected to the motor 61 indirectly via a worm gear 65 which engages in a gear 66 which is on the same axis as that Eccentric disc 62 is located and is non-positively connected to this.
  • the motor axis is aligned parallel to the axis of the guide cylinder 2 'and fastened directly to the guide cylinder 2'.
  • the high force required for the compression is achieved by an appropriate reduction, so that a motor with small dimensions and high speed can be used.
  • cans which can also be stable and large designs (e.g. tinplate cans, paint cans, ...), are introduced through the feed opening 32 into the working cylinder 3 ", it is necessary that the working cylinder 3" in connection with the guide piston 2 "has its largest interior. This is the case when the retaining bolt 67 assumes the position at which it comes to lie closest to the deflection rollers 26 and 26 '. In this position, the retaining bolt 67 also takes its lowest position.
  • the motor 61 is switched on, so that the eccentric discs 62 and 62 'are rotated about the eccentric axis 63 via the worm gear 65. Since the retaining bolt 67 and the transverse bolt 35 are non-positively connected by the cable 45, the transverse bolt 35 is moved relative to the guide cylinder 3 'and thus also the working cylinder 3 "relative to the working piston 2".
  • the working cylinder can assume its basic position at any time, the restoring force required for this is caused on the one hand by gravity and on the other hand by a spring 68.
  • the can press as not shown in the figure, is suspended from its guide cylinder by a wall mounting device on a wall or the like.
