Definitions

  • the invention relates to a method for selectively separating out free-flowing products that are conveyed in a conveying direction along a conveying path in a conveying path, the conveyed products being checked in a control section of the conveying path with a checking device, and being in a sorting section arranged downstream along the conveying path the product that does not meet a predeterminable control criterion is separated from the conveyor track with a suction device and is discharged by arranging the suction device on the conveyor section and generating a suction stream flowing away from the conveyor track for a predefined suction duration in order to suck the product out of the conveyor track.
  • suitable methods are used to selectively separate out and remove those products from the conveyor line that do not meet a predetermined control criterion.
  • the individual products can be recorded with a camera and checked for optical deviations from a specified appearance. It is also conceivable that the weight of the individual products is checked with the control device.
  • a suction pipe is usually brought directly above or next to the conveyor track to the product to be sorted out and a suction flow flowing away from the conveyor track is generated for a predetermined suction duration, with which the product is sucked out of the conveyor track.
  • the extracted product can be fed through the suction pipe to a storage container for rejected products.
  • sucking off the product with a suction device prevents the separated products or, for example, their abrasion or impurities from being blown out of the conveyor track in a more or less uncontrollable manner will.
  • a suction device is, for example, in EP 2 774 693 A shown and described.
  • a suction pipe of the suction device with a suction opening is arranged at a front end of the conveyor track in order to suck off the product falling down from the conveyor track along a fall trajectory at the end of the conveyor track through the suction opening.
  • the suction device is above the conveyor track and the product to be sorted out is usually sucked off upwards through a suction pipe
  • the suction takes place at the front end of the conveyor track, whereby the product to be separated out does not have to be sucked out of the conveyor track, but rather sucked off along a fall trajectory as it falls can.
  • the fall trajectory corresponds to the trajectory of a product falling undisturbed at the front end out of the conveyor track.
  • the suction opening of the suction tube can advantageously be arranged below an upper side of the conveyor track and possibly completely below the conveyor track, so that a suction flow sucked in through the suction opening is not sucked out of the conveyor track and does not impair a product in the conveyor track that follows the product to be sucked off becomes. If the suction pipe with the suction opening is arranged close to the front end of the conveyor track, the product to be sucked off is at the beginning of its falling movement along the falling trajectory and is still comparatively slow, so that the falling product stays in a suction area around the suction opening of the suction pipe for a relatively long time stops.
  • the suction tube can be arranged with its suction opening in the immediate vicinity of the falling trajectory of the falling product, independently of the design and orientation of the conveyor track.
  • the method according to the invention can be used particularly advantageously in the case of a conveyor track designed in the form of a groove.
  • the intake manifold with the Prior to a suction process the suction opening is brought to the front end of the conveyor section and is arranged with the suction opening in or directly on the fall trajectory of the falling product in order to suck off the product to be separated out while it is falling down the fall trajectory, and that the suction pipe with the suction opening after a suction process of is shifted away from the front end of the conveyor track in order not to impede the falling down of a product following in the conveyor section, which product is not intended to be sorted out, along the fall trajectory.
  • the suction tube can be shifted with the suction opening directly into the fall trajectory of the falling product, so that even a low suction power is sufficient to suck the falling product through the suction opening into the suction tube.
  • the suction opening can be arranged and aligned in such a way that the fall trajectory of the falling product runs through a cross-sectional area of the suction opening that is as large as possible and is directed perpendicularly to the fall trajectory.
  • a suction section of the suction tube adjacent to the suction opening can also be useful for a suction section of the suction tube adjacent to the suction opening to have a small angle of less than 45° and preferably less than 20° relative to the fall trajectory of the falling product, so that a suction flow sucked in through the suction opening is essentially parallel to the Fall trajectory runs and the product falling along the fall trajectory is already moving in the direction of the suction opening during its falling movement.
  • the suction flow supports the catching of the falling product with the suction opening of the suction tube and the subsequent removal of the product sucked in through the suction tube.
  • a collecting device for the product to be sorted out is arranged on the suction pipe, adjacent to the suction opening, and that the collecting device is arranged in the fall trajectory before a suction process, in order to catch the falling product with the collecting device, and that the product caught with the collecting device is then sucked out through the suction opening.
  • a suction flow sucking off the product can be generated even before the falling product is caught with the collecting device and the falling product can also be sucked in the direction of the collecting device. It is also conceivable that the suction flow sucking off the product is only generated when the product has already been caught by the collecting device.
  • the collecting device can reduce the suction flow required for sucking off the product or a minimum required suction capacity of the suction device because the suction flow is not used and required to deflect the falling product from the fall trajectory, but is only required to then transport the product that has already been caught out of the collection device through the suction pipe away.
  • the collecting device can be a separately manufactured collecting tray, which is attached to the suction tube in the area of the suction opening in such a way that an air flow sucked in through the suction opening can suck the product caught with the collecting device out of the collecting device through the suction tube.
  • the collecting device can also be a collecting trough or collecting tray formed on the suction tube.
  • the collecting device can also have a collecting area lined with an air-permeable material.
  • the collection area can be formed, for example, by a grid, a net or a textile material, so that an air flow sucked in through the suction opening can also flow through the collection area of the collection device.
  • the collecting device is displaced relative to the suction opening after the collecting of the product to be sorted out, in order to facilitate the sucking off of the product through the suction opening.
  • the collecting device can be folded in the direction of the suction opening or pivoted or shifted into an arrangement that almost completely covers the suction opening in order to separate out the liquid to convey the product through the suction opening into the suction tube.
  • the product caught in the collecting device can no longer fall out of the collecting device during a subsequent displacement of the suction pipe.
  • a suction section of the suction tube adjoining the suction opening can be aligned at an angle of less than 45°, preferably less than 20°, relative to a horizontal plane during a suction process.
  • a substantially horizontal alignment of the suction tube and thus of the air flow sucked into the suction tube through the suction opening can cause a comparatively strong deflection of the falling product from the fall trajectory.
  • the suction opening is arranged directly at the end of the conveyor track, the air flow sucked into the suction tube through the suction opening can be aligned in such a way that it essentially coincides with the movement of the separated product in the conveying direction along the conveyor track and the movement of the product towards the end of the Conveyor track is used to favor the rejection of the product during suction with a suction flow directed in the same direction.
  • the suction opening of the suction tube of the suction device encompasses the front end of the conveyor track at least in sections during the suction process.
  • the suction tube can be adapted to the conveyor track or to the front end of the conveyor track in the area of the suction opening Have a shape so that the suction opening fits snugly against the front end of the conveyor track. The suction flow sucked in through the suction opening is then sucked out of the conveyor track very effectively, so that a product located there and to be separated out is reliably sucked off even with a low suction power.
  • the positioning of the suction opening relative to the front end of the conveyor track can be specified particularly reliably by contact of the suction tube with the front end of the conveyor track. It is also possible to arrange the suction tube with the suction opening at a small distance from the front end of the conveyor track. A small gap does not significantly affect the suction of a product to be sorted out and can, for example, offer advantages due to the design.
  • the suction opening with the suction section adjoining the suction opening can be brought up to the front end of the conveyor track at an angle from above or from below the conveying direction and positioned during the suction process.
  • the invention also relates to a device for selectively separating out free-flowing products with a conveyor track running in a conveying direction up to a front end of a conveying section, and with a suction device with a suction tube opening into a suction opening.
  • the conveyor track can be designed in the form of a groove and either convey several products next to one another or have only one narrow groove-shaped indentation or several narrow groove-shaped indentations only one row of products arranged one behind the other in the conveying direction can be located in each groove-shaped depression.
  • the suction pipe with the suction opening is usually arranged directly above the conveyor track in order to suck the product to be separated out upwards from the conveyor track before the product leaves the conveyor track. It cannot be ruled out that the suction process with the suction device influences a subsequent product and, for example, the fall trajectory of the falling product is changed due to its acceleration, so that reliable conveying and further processing of the product can be jeopardized.
  • the suction tube is mounted displaceably on the front end of the conveyor track in such a way that the suction tube with the suction opening is displaced below an upper side of the conveyor track into or onto a fall trajectory of a product falling out of the conveyor track at the front end and towards can be shifted away from the fall trajectory after the completion of a suction process.
  • the product to be sorted out can be sucked off to the side or downwards while it is falling out and falling from the front end of the conveying path, without the suction flow required for sucking off being able to influence a product following in the conveying track.
  • the suction tube can be directly in the fall trajectory of the falling Product are shifted into it, so that the product falling along the fall trajectory falls through the suction opening into the suction tube even without a suction flow or with an already low suction flow and can thus be reliably separated out.
  • by subsequently moving the suction tube away from the fall trajectory it can be ensured that neither the suction tube itself nor a suction flow generated in the vicinity of the suction opening can influence the falling of a subsequent product and thereby disrupt it.
  • a collecting device for the product to be sorted out is arranged on the suction pipe and adjoins the suction opening.
  • the collecting device expediently has a trough or bowl-shaped collecting area for the product to be separated out.
  • the catching device is expediently arranged in the fall trajectory of a product that is falling and to be sorted out, so that the product falls into the catching device even without a suction flow and is caught by the catching device. The collected product can then be sucked out of the collecting device through the suction pipe with the suction stream.
  • the collecting device has at least one air-permeable flow opening through which a suction flow directed in the direction of the suction opening of the suction tube can at least partially flow through.
  • the air-permeable flow opening can be formed, for example, by a grid, a net or a textile material that is arranged in a collection area of the collection device and surrounded by a suitable frame.
  • a conveying section 1 with a conveying path 3 aligned in a conveying direction 2 is shown schematically.
  • the conveyor track 3 there are two tablet-shaped products 4 which are conveyed along the conveying direction up to a front end 5 of the conveyor track 3 .
  • the conveyor section 1 is designed as a vibration conveyor, so that the products 4 in the conveyor track 3 are conveyed by directed vibration movements of the conveyor section 1 in the conveying direction 2 up to the front end 5 of the conveyor track 3 .
  • the tablet-shaped products 4 fall out of the row of conveyor belts and down along a fall trajectory 6 into a packaging container 7 arranged below the front end 5 of the conveyor track 3.
  • the fall trajectory 6 corresponds to a trajectory of the products 4, which without external influence fall out of the front end 5 of the conveyor track 3 and then fall down due to gravity.
  • a suction device 8 with a suction pipe 10 opening into a suction opening 9 is arranged laterally in the immediate vicinity of the fall trajectory 6 .
  • a vacuum can be generated in the suction pipe 10 with a vacuum generating device, not shown, so that in a suction area in front of the suction opening 9 suction flow 11 directed into the suction pipe 10 is generated.
  • the suction pipe 10 is arranged with its suction opening 9 on the fall trajectory 6 in such a way that the suction flow 11 flows through the fall trajectory 6 and a product 4 falling along the fall trajectory 6 is caught by the suction flow 11 and sucked through the suction opening 9 into the suction pipe 10.
  • FIG 2 another variant of the method according to the invention is shown schematically.
  • the suction pipe 10 with the suction opening 9 is brought up to the front end 5 of the conveyor track 3 immediately before the start of a suction process and arranged in such a way that the fall trajectory 6 of a falling product 4 would run through the suction opening 9 .
  • the product 4 to be sorted out is already being conveyed in the direction of the suction opening 9 during conveyance in the conveyor track 3 .
  • a suction section 12 adjoining the suction opening 9 has a small angle of less than 20° relative to a horizontal plane, or relative to the alignment of the conveyor track 3 .
  • the suction pipe 10 with the suction opening 9 is removed from the front end 5 of the conveyor track 3 again.
  • the subsequent product 4 can then fall undisturbed along the fall trajectory 6 and, for example, fall into a packaging container or a subsequent conveyor section.
  • FIG 3 a differently configured suction device 8 is shown.
  • a cup-shaped collecting device 13 adjoining the suction opening 9 is formed on the suction tube 10 .
  • the suction pipe 10 can be arranged with the collecting device 13 below the conveyor track 3 in such a way that the fall trajectory 6 opens into the collecting device 13 or the collecting device 13 passes through.
  • the product 4 falling at the front end 5 along the fall trajectory 6 then falls into the collecting device 13 and can be sucked out of the collecting device 13 through the suction pipe 10 with a suction stream 11 with a low suction power.
  • the suction pipe 10 with the collecting device 13 In order to prevent products 4 that are not to be sorted out from being impaired or even sorted out if they fall down along the fall trajectory 6, the suction pipe 10 with the collecting device 13 must be inserted into the fall trajectory 6 immediately before the start of a sorting process and then out of the fall trajectory 6 again be outsourced.
  • the suction process can also only begin a little later, when the product 4 to be separated out has already been collected with the collecting device 13. If necessary, the suction process can only begin when the suction pipe 10 with the suction opening 9 and the collecting device 13 has already been removed from the fall trajectory 6 again.
