  • The invention relates to a device for clearing lying on a web-bound conveyed a Förderanlagenschlusses, arranged in a fire or mounting wall conveying passage opening, which is associated with a shut-off with a closing plate, which consists of an opening adjacent to the opening in an open Opening above the conveyor closing position by a drive on guide elements along a horizontal above the opening guide rail is transversely movable transversely to the conveying direction, the drive of the shut-off is connected to a central control, which stops the conveyor in case of fire or malfunction, and with a the Opening below the conveyor sealing sealing block.
  • The invention further relates to a method for clearing conveyed goods lying on a belt-bound conveyor of a conveyor system termination, in which the conveyor is guided through a delivery passage opening and is shut down in the event of fire or malfunction, so that conveyed material can remain in the delivery passage opening, moves this conveyed from the area of the delivery passage opening and the delivery passage opening in case of fire or accident is closed by a closing plate of the shut-off, said closing plate from an opening adjacent to the opening in an opening above the conveyor closing position by a drive horizontally can be moved transversely to the conveying direction, wherein the drive of the shut-off element is actuated by a central control,
  • State of the art
  • Closing elements for wall openings, through which rail, chain or belt-shaped conveyors of a conveyor system are guided, have long been state of the art ( DE 26 20 536 B2 . DE 27 20 684 A1 . DE 28 08 439 A1 . DE 29 01 299 A1 . DE 29 14 228 A1 . DE 30 04 044 A1 . DE 3417 781 C2 . US 5,373,932 A ). All these known solutions have the disadvantage in the event of fire that the conveyed remains lying in the closing area of the closure elements due to the shutdown of the conveyor and obstructs the closing process or even impossible. This problem is being tried DE 26 20 036 B2 to be solved by a stripping, which has a Abstreifarm which is pivotable about an arranged in the vicinity of the conveyor belt edge perpendicular to the conveying plane axis and strips the conveyed material from the conveyor belt during pivoting. However, if the conveyed material is still completely or partially in the delivery passage opening of the wall, this solution fails.
  • Furthermore, from the DE 27 20 684 A1 a fire protection closure for conveyor openings in partitions known in which the delivery passage opening is closed by a closing plate in the vertical direction. The closing plate carries a horizontally oriented stripper plate, which performs a pivoting movement when closing, cleared by the conveyor located in front of the conveying passage opening conveyed by the conveyor. Also, this known prior art can not eliminate conveyed material located in the delivery passage opening, so that the closing of the delivery passage opening is possible only by manual intervention.
  • The DE 31 05 892 A1 proposes at a fire protection in the course of railway-bound conveyors to wall breakthroughs o. The like. To clear the conveyor in case of fire before a clearing device, which is passed through the fire protection through a conveyor position in which it is outside the opening and in case of fire in a clearing position movable is, wherein the Abräumer moves on the conveyor track and out of the area of the Feuerschutzabschlusses is moved out again. The Abräumer requires rails on which it is guided and moved by a cable. It can be provided with a broom, brushes or a blower for clearing the conveyor of bulk material.
  • Another known solution ( DE 42 06 451 C2 ) provides a closure device for closing an opening in the event of a malfunction by a movable closure element. The conveyor for transporting pourable and / or lumpy goods is passed through the opening and is stopped in case of failure. It is a clearing device provided with a movable Abläumelement which is held in the trouble-free state out of engagement with the cargo and in the event of failure before closing the opening with the transport material located on the conveyor path is engageable and this clears the movement area of the closure element. The clearing element is mounted on the side facing away from the closure element of the opening and the part of the Abräumelements which can be brought into engagement with the item to be transported is kept above the maximum transport goods height in the uninterrupted state. In case of failure, this part is lowered behind the closure element on the conveyor track and then pulled along this through the opening.
  • Although these solutions may be suitable for clearing away fine-grained or lumpy bulk material, but are not suitable for conveyed goods such as packages, parcels, containers, boxes, cans or bottles. Moreover, this solution is structurally and mechanically complicated. It also needs a lot of space and their application is often vulnerable and uneconomical due to the cables.
  • task
  • In this prior art, the present invention seeks to provide a device and a method for clearing lying on a conveyor conveyed a Förderanlagenabschlusses, with the conveyed without a separate Abläumeinrichtung simplifying the construction while increasing the robustness and safety and the Saving space can be removed from the conveyor passage and the closing area of the closure element.
  • This object is achieved by a device of the aforementioned type with the features of claim 1 and by a method having the features of claim 12.
  • Advantageous embodiments of the device and the method according to the invention can be taken from the subclaims.
  • The solution according to the invention is based on the knowledge that the conveyed material is already clamped in the conveying passage opening by roller-like clearing elements which can be pressed against each other transversely to the conveying direction and moved out of the conveying passage opening or the closing area of the closing element by means of friction. This is achieved in that the horizontally movable closing plate on its side facing the vertical reveal of the conveying passage opening facing a moving, displaceable by a drive in rotation transport element and provided on its longitudinal side with a above the conveyor of the closing plate perpendicular projecting in the conveying direction stiffening web is at whose soffit facing end face hineinbewegbares in the conveying plane of the conveyor slide plate for lifting the conveyed material is attached, and that is fixedly arranged in the facing away from the end face of the slide plate a displaceable by a drive in rotation transport element, which with the slide plate moving transport element and fixed in the soffit transport element with their axes of rotation are mutually offset so arranged that the moving transport element pushes the conveyed against the stationary transport element t and both transport elements move the conveyed either in or against the conveying direction of the conveying passage opening and the closing plane.
  • In an advantageous embodiment of the device according to the invention, the direction of rotation of the moving transport element in the clockwise or anticlockwise direction and the direction of rotation of the stationary transport element can be aligned in the counterclockwise or clockwise direction, whereby depending on the position of the conveyed material in the delivery passage opening a particularly rapid response an emergency stop can be guaranteed.
  • According to a further preferred embodiment of the device according to the invention it is provided that the transport element depending on the nature, shape and weight of the conveyed a paddle wheel with a plurality of flexible blades, a brush roller with full stock, Segmentbesatz or with parallel rows of bristles, a roller made of solid rubber or Plastic with smooth or textured surface or a steel roller with rubber coating includes.
  • Especially for bulky goods such as parcels weighing up to 50 kg, paddle wheels with at least three, preferably four, airfoils arranged uniformly distributed around the circumference of the axis of rotation have proven to be effective. The blades can be made of sheet metal with a flexible covering made of plastic, solid rubber or rubber or plastic-reinforced fabric. Of course it is also possible to use plastic blades. It must only be ensured that the blades are sufficiently flexible and not too hard, so that the friction forces on the side walls of the conveyed goods are sufficiently large. For glass conveyed goods, such as bottles, paddle wheels should be used, the blades of which have a distance from each other, which is smaller than the diameter of the bottles.
  • It is also advantageous if the moving transport element offset in height relative to the stationary transport element with respect to the conveying plane and its axis of rotation in relation to the slide plate is arranged so that the blades or bristles of the transport element can engage over the slide plate. Of particular importance is that a arranged on the underside of the slide plate roller-like roller is provided for low-friction movement of the slide plate on the conveyor plane, wherein the slide plate with the conveying plane forms an angle α of 10 ° to 15 °. This ensures that the raised side of the conveyed material lying on the slide plate can easily be moved in the conveying direction.
  • In a further preferred embodiment of the device according to the invention, the blades of the stationary transport element have a length which corresponds to at least 60% to a maximum of the vertical height of the conveyed material, wherein the blades of the moving transport element have a length which corresponds to the length of the Blades of the stationary transport element corresponds. This design of the airfoils, in conjunction with the force exerted by the moving transport element pressing force, the conveyed lying on the conveyor material by friction out of conveyor passage opening to move out without a special broaching is required.
  • A further advantage is that the drive for the transport elements is a battery-powered DC motor with a low ratio, the DC motors are driven with the same or different speeds / torques depending on the application with or without slip and connected to the central control. However, it is also part of the invention, when the drive for the transport elements is in each case an AC motor, which is powered by an inverter from a battery with power. The speeds of the two AC motors can be set differently via a converter and are connected to the central control. This can be useful if the weight of the conveyed material is distributed unevenly.
  • The object of the invention is further achieved by a method comprising the following steps:
    • a) determining the position of the conveyed material in the conveying passage opening and the distance of the conveyor on the closest individual piece of the conveyed by a position sensor which is connected to the central control, which from the position and the distance of the conveyed the direction of movement of the conveyed material in or determined contrary to the conveying direction,
    • b) generating a laterally acting on the conveyed force component by a fixed to the soffit of the delivery passage opening fixed transport element which is rotated via the central control with a drive in rotation, as soon as the direction of movement of the conveyed material is determined
    • c) optionally generating a laterally acting on the conveyed force component by a moving with the closing plate transversely to the conveying direction transport element, the same time with the step b) via the central control with a drive in accordance of movement and conveying direction in rotation and on the one hand with a by a Slip clutch on the drive of Absperrelementes adjustable contact pressure against the conveyed and on the other hand pressed against the stationary transport element, wherein the conveyed is raised by a the intervention of the moving transport element in the closing direction leading unilateral lifting with a fixed to the closing plate slide plate and
    • d) moving out of the conveyed by a force resulting from the friction force between the conveyed and the stationary transport element, if the rotation direction is set against the conveying direction, or by a resulting from the friction forces between the conveyed between the moving and stationary transport element and the closing force resulting force in or against the conveying direction from the conveying passage opening and the closing area of the closing plate.
  • In a preferred embodiment of the method according to the invention, the direction of rotation of the moving transport element in the clockwise or Gegenuhrzeigesinn and the direction of rotation of the stationary transport element can be adjusted in the counterclockwise or clockwise direction.
  • Of essential importance for the method according to the invention is that the transport elements via the drives separately from the central control depending on the nature, shape and weight of the conveyed are driven at the same or different speed in the clockwise and counterclockwise, so that the two transport elements in pairs form a forced transport path for the conveyed material, whereby the conveyed material is moved out of the Fördergutdurchlass-opening.
  • In a further embodiment of the method according to the invention, the compressive force exerted by the moving transport element on the conveyed material and the stationary transport element is adjusted by a slip clutch on the drive of the shut-off element.
  • According to a further advantageous embodiment of the method according to the invention, depending on the type, shape and weight of the conveyed transport elements in the form of a paddle wheel with a plurality of flexible blades, a brush roller with full stock, Segmentbesatz or with parallel rows of bristles, a roller made of solid rubber or plastic smooth or textured surface or a steel roller with rubber / plastic coating can be used.
  • Further advantages and details will become apparent from the following description with reference to the accompanying drawings.

  • The 1 shows a perspective view of a conveyor system closure with the device according to the invention, on a fire protection or mounting wall 1 is arranged. The fire protection or mounting wall 1 has a rectangular delivery passage opening 2 through which a promoter 3 , For example, a Plattengurtförderer, is passed. The delivery passage opening 2 is a fireproof shut-off element 4 associated with that in trouble-free condition next to the delivery passage opening 2 in an open position. Above the delivery passage opening 2 is a horizontally extending guide rail 5 attached to the the closing plate 6 the shut-off is suspended and by means of a circulating chain or toothed belt 7 , Chain or belt pulleys 8th and a drive 9 from the open position into a delivery passage opening 2 Closing position is horizontally movable. The drive 9 is equipped with a slip clutch for the required contact pressure of the elements described later 14 and 18 to the conveyed goods 22 provides. The space of the delivery passage opening 2 below the conveyor 3 is by a on the striker side sealing block 10 made of non-combustible calcium silicate plates.
  • At the lower conveying plane FE of the conveyor facing longitudinal side LS of the closing plate 6 of the shut-off element 4 is a stiffening bridge 11 attached, perpendicular to the striker plate 6 stands up and with holding profiles 12 at the closing plate 6 is fixed. The soffit 13 the delivery passage opening 2 facing end face ST of the closing plate 6 holds a transport element 14 , which is about an axis of rotation located parallel to the closing plane SE and perpendicular to the conveying plane FE 15 via a drive 16 For example, a battery-powered DC electric motor is rotated clockwise with a low gear ratio in rotation at a uniform speed. When executing the closing movement of the closing plate 6 transversely to the conveying direction FR thus moves the transport element 14 in the closed position and thus immediately traverses the area in front of the delivery passage opening 2 , In the front side ST of the closing plate 6 facing away soffit 17 the delivery passage opening 2 is a transport element 18 arranged around a parallel behind the closing plane SE, perpendicular to the conveying plane FE towering axis of rotation 19 , via a drive 20 , For example, battery-assisted DC motor is set at a low gear ratio in rotation, wherein the speed at the same speed as the moving transport element 14 , but is adjusted counterclockwise. Of course, if required by the application, the drive may be provided with a slip clutch.
  • It is now on the 2 and 3 Referenced. The drive 9 of the shut-off element 4 and the drives 16 and 20 the transport elements 14 and 18 are via a corresponding sensor with a central control 21 connected to the speed of the drives depending on the shape, size and weight of the conveyed material 22 regulates. The traveling transport element 14 is opposite to the stationary transport element 18 with respect to the conveying plane FE to such an extent with its axis of rotation 15 arranged offset in height, that one at the stiffening web 11 attached slide plate 23 can sit on the conveying plane FE at an angle α of 10 ° to 15 °.
  • The rotation axis 15 is with the drive 16 connected via the gearbox. The slide plate 23 extends over the entire width of the stiffening web 11 and is at its bottom 24 with a cylindrical roller bearing 25 provided with holding arms 26 at the side edges 27 the slide plate 23 is fixed freely rotating, so that a low-friction support of the slide plate 23 is guaranteed on the conveyor.
  • The traveling transport element 14 is as a paddle wheel 28 formed, the four blades 29 which is about the axis of rotation 15 each enclose an angle β of 90 °. The blades are made of a fixed to the axis of rotation plate on which plates of flexible material, for example made of solid rubber, are attached. The blades 29 of the stationary transport element 18 have a length L which is about 70% of the vertical side edge length (height) of the conveyed material 22 corresponds (see 1 ). The length L1 of the blades 29 of the moving transport element 14 corresponds to the length L of the blades of the stationary transport element 18 , The rotation axis 15 of the transport element 14 takes in relation to the slide plate 23 such a location that the blades 29 the slide plate 23 can spread over.
  • As the 2 further clarified, is the stationary transport element 18 at the soffit 17 within the delivery passage opening 2 , The rotation axis 19 of the stationary transport element 18 lies behind the closing level SE of the shut-off element 4 at a distance A to the rotation axis 15 of the moving transport element 14 staggered (see 3 ). The structure of the stationary transport element 18 corresponds in number, type and shape of the blades 29 that of the mobile transport element 14 ,
  • At the front side ST of the closing plate 6 of the shut-off element 4 located soffit 13 is one with the central control 21 connected position sensor 30 arranged the position data to the central control 21 passes which the location of the conveyed goods 22 in the delivery passage opening 2 and the distance B on the conveyor 3 lying Fördergutstücken before and behind the closing level SE determined and corresponding control commands to the drives 9 . 16 and 20 outputs.
  • The 4a to 4g show variants of transport elements 14 and 18 , which are formed in pairs the same. In the 4a and 4b are paddle wheel variants with four or eight paddle wheels 29 shown. The 4c shows a smooth roller of steel, plastic or rubber, the 4d a roller with a coating of plastic or rubber, the 4e a roller with coating with nubs that 4f a brush roll with full stock and the 4g a brush roller with centered brush trim. Of course, it is also possible to use other shapes such as spherical or convex roll shapes, if required by the nature, shape and weight of the conveyed goods, without departing from the invention.
  • The course of the method according to the invention is based on the 5a and 5b described. In case of failure or fire, the central control triggers 21 an emergency stop, the sponsor 3 shuts down. The on the conveyor 3 lying individual packages can thus with respect to the delivery passage opening 2 to take any position. In other words, the conveyed goods 22 can like 5a shows with its front edge in the conveyor passage opening 2 before reaching the closing plate 6 to come to rest. The at the soffit 13 arranged optical position sensor 30 , preferably light barrier, detects the position of the conveyed material 22 in the conveyor passage opening 2 and the distance B on the conveyor 3 lying individual pieces of the transported material 22 from each other and transmit this data to the central control 21 , which the direction of rotation of the transport elements 14 and 18 or shear direction of the conveyed material 22 determined in or against the conveying direction and the drives 9 . 16 and 20 governs accordingly. In this case, the stationary transport element is detected 18 with its anticlockwise rotating blades 29 the side wall SW of the conveyed material 22 that the stationary transport element 18 is facing and pushes the conveyed 21 in conveying direction FR at least so far that the paddle wheels 29 of the moving transport element 14 the other side wall SW1 of the conveyed material 22 can capture. The drive 9 of the shutoff element 4 exerted closing force SP presses the moving and clockwise rotating transport element 14 on the one hand against the side wall SW1 of the conveyed material 22 and on the other hand, the side wall SW against the fixed counterclockwise rotating transport element 18 , The conveyed goods 22 is in a sense between the two mutually offset rotating transport elements 14 and 18 clamped.
  • So the conveyed 22 from the transport elements 14 and 18 can be detected, it requires a certain contact pressure, which here by acting transversely to the conveying direction FR closing force SP of the shut-off 4 is made available. This occurs when touching the side walls SW or SW1 of the conveyed material 22 through the blades 29 a force on. Because the airfoil 29 rotates, the contact point continues to move, whereby friction forces PR arise, which are tangent to the trajectory of the paddle wheel. These friction forces PR can each be decomposed into a horizontal force component PRH and into a vertical force component PRV. The drives 16 and 20 of the moving or stationary transport element 14 and 18 be from the central control 21 in their speeds and torques adjusted so that the blades 29 the frictional forces FR on the side walls SW and SW1 can overcome and conveyed 22 is pushed out of the clamping in the conveying direction FR. The closing force of the shut-off element 4 and thus the contact force of the moving transport element 14 is via the slip clutch of the drive 9 set. In 5b an example is shown in which the distance B of the individual pieces of the conveyed material 22 each other is greater than the dimension of the conveyed material in the conveying direction. In such a case, the thrust direction becomes clear of the conveyor 3 chosen contrary to the conveying direction FR, because this way is shorter and enough space on the conveyor 3 is available.
  • The inventive method runs in detail steps during the displacement of the closing plate 6 from the open position into the closed position as follows:
    • a) Determining the position of the conveyed material 22 in the delivery passage opening 2 and the distance B on the conveyor 3 next single piece of the transported material 22 through a position sensor 30 that with the central control 21 is connected, which from the position and the distance B of the conveyed material 22 determines the direction of movement of the conveyed material in or against the conveying direction FR,
    • b) generating a on the conveyed 22 laterally attacking force component by a s.der soffit 17 the delivery passage opening 2 fixedly fixed transport element 18 that via the central control 21 with a drive 20 is set in rotation as soon as the direction of movement of the conveyed material 22 is determined
    • c) optionally generating one on the conveyed material 22 laterally acting force component by a with the closing plate 6 transversely to the conveying direction FR mitfahrendes transport element 14 at the same time as step b) via the central control 21 with a drive 16 coincided with the direction of movement with the conveying direction in rotation and on the one hand with a by a slip clutch on the drive 9 of the shut-off element 4 adjustable contact pressure SP against the material to be conveyed 22 and on the other hand against the stationary transport element 18 is pressed, wherein the conveyed 22 by a the engagement of the moving transport element 14 in the closing direction leading one-sided lifting with one on the closing plate 6 fixed slide plate 23 is raised and
    • d) moving out of the conveyed material 22 by one of the friction between the conveyed 22 and the stationary transport element 18 resulting force, if the rotation direction is set against the conveying direction FR, or by one of the friction forces between the conveyed 22 between the moving and stationary transport element 14 and 18 and the pressing force SP resulting force in or against the conveying direction FR from the delivery passage opening 2 and the closing area of the closing plate 6 ,
