Definitions

  • the invention relates to a device for sorting small parts of different sizes, with an inclined slide plate for placing the small parts and with a device extending a passage gap for small parts up to a predetermined size extending to the slide plate device for separating and conveying larger small parts lengthways of the passage gap.
  • Devices of this type are used in particular for sorting the small parts ejected from plastic injection molding machines.
  • these small parts are waste-forming sprue parts.
  • the invention relates in particular to a device for sorting the small-part ejection of plastic injection molding machines according to small technical parts and cast-on parts.
  • the parts to be sorted are fed by means of a conveyor belt or another suitable conveying device at the upper end of an inclined slide and then slide between the latter and a screw arranged transversely to the direction of fall of the slide at a distance therefrom, which is opposite to the direction of fall the slide is motor-driven all round.
  • the distance between the screw and the slide is set so that the smaller parts fall through, while the larger parts along the screw are removed laterally.
  • the invention is therefore intended to provide a device of the type and intended use specified above with improved separating and sorting capacity compared to the prior art.
  • the passage gap is designed as a channel which runs essentially transversely to the fall line of the slide plate, one of which adjoins the slide plate and the device for separating and conveying small parts Plate is limited, and that said device is provided with means for intermittent lifting or throwing up small parts that are stowed in front of the channel.
  • the place of the known passage gap is replaced by a pronounced channel through which such small parts fall, the extent of which in at least one direction is smaller than the channel width.
  • Larger parts, such as sprue parts, but also parts hooked together, are thrown up intermittently by the device mentioned and then fall back onto the slide plate and in the channel direction, with separation of smaller parts from larger parts taking place and the latter being gradually removed in the channel direction while the small parts separated from larger parts fall through the channel.
  • the slipping plate sloping towards the channel is also inclined in the longitudinal direction of the channel and, in addition, the relevant angle of inclination with respect to the horizontal is adjustable. This enables adaptation to the parts to be separated from one another and, in particular, adjustment of the speed of the lateral removal of the large parts.
  • the device for separating and conveying small parts along the channel as a means for lifting or throwing up such parts comprises an intermittently vertically movable oscillating plate which does not pass through the channel during its upward and downward lifting movements throws up larger parts or interlocked parts.
  • the device for separating and conveying small parts along the channel comprises an intermittently vertically movable oscillating plate which does not pass through the channel during its upward and downward lifting movements throws up larger parts or interlocked parts.
  • a particularly effective separation of hooked parts is achieved in this device if at least regions of the oscillating plate, during its intermittent lifting movement, run over an edge between the slide plate and the channel adjoining it with a noticeable amplitude. Characteristic of this development are therefore large lifting movements of the oscillating plate and expediently the amplitude of these lifting movements of the oscillating plate should be changeable.
  • the vibrating plate extends diverging from the slide plate and - seen in cross section - forms together with the latter a funnel narrowing towards the channel, which inevitably feeds the sorted material placed on the slide plate to the channel. Sorted material that slides in the direction of fall over the slide plate thus strikes the vibrating plate at an angle and is thrown up and thrown back onto the slide plate during its intermittent lifting movements. This process is repeated for the parts that do not pass through the channel during the entire transverse conveying path, with the result that extremely effective separation of interlocked parts and thus virtually complete separation of parts of different sizes occurs.
  • the frequency of the lifting movements of the oscillating plate can expediently be changed in addition to the amplitude.
  • the drive of the vibrating plate can be pneumatically by means of at least one on the vibrating plate attacking and carried out intermittently with a predetermined frequency with pressure medium working cylinder.
  • the drive of the oscillating plate can, however, also be realized by means of an electric geared motor, wherein the output-side rotary movement of the motor is converted into linear movements via a push crank, the crank rod of which is articulated on the oscillating plate with its end remote from the crank.
  • the latter drive has proven to be advantageous in that when using a motor that is controllable in terms of its speed, the stroke frequency of the oscillating plate can be changed in a simple manner.
  • the width of the channel forming the passage gap is adjustable.
  • the slide plate and the plate delimiting the channel on the side thereof can be infinitely adjustable at right angles to the longitudinal channel extension, for example by means of a spindle which enables fine adjustment.
  • the device designated in its entirety by 10, has a slide plate 12, which is received between two end plates 11, 11 'and drops towards an elongated channel 14 of adjustable width.
  • a plate 16 delimiting the channel 14 on one side
  • a plate 18 delimiting the application area stands up.
  • the slide plate 12 with the associated plate 16 for delimiting the channel 14 on one side and also the plate 18 standing up from the feed side are firmly received between the end plates 11, 11 '.
  • horizontal guides 20, 20' are arranged on the mutually facing sides, each with a horizontally movable carriage 21, 21 'which can be locked in any setting position.
  • These carriages are firmly connected to the ends of a cross-member 22, which in turn is firmly received on lateral supports 23, 23 'of a support frame 25 provided with a stand 24.
  • the ends of the crossmember 22 are different from the simplified illustration in Fig. 1 - not directly connected to the slide 21, 21 'of the horizontal guides 20, 20', but via vertically extending and equally connected to the crossbar 22 and a slide 21, 21 'intermediate pieces 26, 26'.
  • the device has a vertically movably guided oscillation plate 30, to which a plate 32 adjoins the channel 14 on the oscillation plate side along an edge 31 on the channel side.
  • the oscillating plate 30 with the associated plate 32 for limiting the channel 14 on one side is, as indicated by the double arrow 33 in FIG. 1, guided in a vertically movable manner and can be driven at a predetermined stroke frequency by means of an electric geared motor 34 which is connected to one with the crossbar 22 fixedly connected support plate 35 is mounted.
  • the vertical guide 36 of the oscillating plate 30 comprises two guide columns 37, 37 ', a bracket 38 firmly connected to the oscillating plate and one guide piece 39, 39' received on each guide column, which is on both sides of the geared motor 34 on the side facing the oscillating plate on the support plate 35 are firmly arranged.
  • the vertical drive of the oscillating plate 30 is mediated by a thrust crank 40 which converts the rotary drive movement of the geared motor into linear movements, the crank 41 of which is received on the output shaft of the geared motor 34 extending through the support plate 35 and the push rod 42 with its end remote from the crank at 43 to the console 38 of the oscillating plate is pivotally articulated.
  • the geared motor 34 is expediently a speed-controllable motor which enables the stroke frequency to be set in accordance with the respective operating conditions.
  • the slide plate 12 with the plate 16 adjoining it and delimiting the channel 14 on one side extends between the two end plates 11, 11 ', while the vertically movable oscillating plate 30 extends with the other plate 32 delimiting the channel 14 on one side as far as the end plate 11, but on the other side ends at a noticeable distance from the corresponding other end plate 11 '.
  • the beginning of the channel defined by the lower longitudinal edges 15, 31 of the slide plate 12 on the one hand and the oscillating plate 30 on the other hand is inclined relative to the horizontal by a predetermined adjustable angular dimension to the side of the device on which the oscillating plate 30 is at a noticeable distance from that on the latter Side arranged end plate 11 'ends.
  • the slide plate 12 abandoned small parts as a result of the intermittent lifting movements of the oscillating plate 30 continuously raised at right angles to the longitudinal channel extension and fall back again.
  • the small parts that do not fall through the channel experience a gradually progressive cross-conveyance up to the end of the oscillating plate, where the small parts that do not fit through the channel now drop unhindered and get into a corresponding receptacle, while the previously through the Small parts that have fallen through the channel can be accommodated in another receptacle.
  • the angle at which the beginning of the channel defined by the lower edges 15, 31 of the slide plate 12 and the oscillating plate 30 is determined can be changed.
  • the width of the channel 14 can be changed by the slide plate 12 with the plate 16 delimiting the channel on one side perpendicular to the longitudinal channel extension by means of the slides 21, 21 slidably received in the horizontal guides 20 'is moved.
  • the mentioned slides can be locked in any setting position.
