Description

The present invention relates to a belt feeder according to the preamble of patent claim 1.

Band feeders are an important component in modern packaging systems. They make it possible to selectively remove a workpiece from a large number of workpieces, in particular essentially flat workpieces, and feed it to a subsequent processing or packaging process. In general, the workpieces are inserted as a stack in a magazine of Bandanlegers. During singulation, the lowermost workpiece in the stack comes into contact with at least one singulating belt and at least one singling roller corresponding to this singling belt and is removed from the stack. Thereafter, the separated workpiece is transferred in the transport direction in a discharge area, from where the further processing or packaging takes place. For example, the workpiece can be printed, glued, packaged or welded.

A belt feeder known from the prior art for separating a plurality of stacked, substantially flat products generally has a drive, a separating arrangement and an outlet arrangement, wherein the separating arrangement has at least one separating belt and at least one separating roller arranged in such a way and from are hinged to the drive that individual products are transferred between the separating belt and the separating roller through into the outlet arrangement, and wherein the outlet arrangement has at least one upper outlet extension with an upper outlet conveyor and a lower outlet extension with a lower outlet conveyor, such arranged to each other and articulated by the drive that the separated product is conveyed between the bands.

In the known from the prior art band investors, it is considered disadvantageous that a fault clearance is relatively complex and brings a change of Verscheißteilen usually disassembly of a large number of components of Bandanlegers with it.

It is the object of the present invention to provide a band feeder in which a fault elimination can be done in a simpler manner.

This object is achieved by a belt feeder with the features of claim 1.

An inventive strip feeder for separating a plurality of stacked, substantially flat products has a drive, a separating arrangement, at least one separating belt and at least one separating roller, which are arranged to each other and articulated by the drive that individual products between the singling belt and the singling roller through be transferred to the outlet arrangement, wherein an adjusting arrangement for adjusting a first distance between the separating roller and the separating belt is provided, and wherein the outlet arrangement comprises at least one upper outlet extension with an upper outlet conveyor and a lower outlet extension with a lower outlet conveyor arranged in such and such are articulated by the drive that the separated product is conveyed between the belts, wherein a pivoting arrangement is provided, via which the separating roller pivotally mounted on the adjusting arrangement and can be fixed by means of a fixing arrangement in a predetermined position.

Due to the fact that the separating roller or the separating rollers are pivotably mounted on the adjusting arrangement and can be fixed in a predetermined position by means of a fixing arrangement, on the one hand a distance between the separating roller and the separating belt in the fixed position can be set exactly and on the other hand after loosening Fixing the separation roller can be pivoted away from the separation belt, so that disturbances in the area of the separation arrangement can be easily eliminated.

Advantageously, the fixing arrangement is designed as a latching arrangement.

In this way, a particularly simple fixation of the swivel assembly is achieved on the adjustment assembly, at the same time by a locking a defined orientation can be achieved.

A particularly accurate alignment of the pivoting arrangement to the adjusting arrangement can be achieved if the latching arrangement is formed with conical indexing bolts. By using tapered index pin radial play, as it occurs, for example, in cylindrically shaped index pin can be eliminated. By the sliding together of the conical index pin and a conically shaped detent opening as well, the radial clearance by a complete resting of the surfaces of the bolt and opening eliminated and simultaneously causes a centering of the arrangement.

In order to transmit an adjustment of the first distance between the separating roller and the separating belt also on the outlet arrangement, it is advantageous if a coupling is provided between the adjusting arrangement and a storage of a rear lying in the transport direction of the upper spout extension, which is designed such that a change in the first distance causes a change in the second distance between the upper and the lower outlet extension.

By such a coupling, it is possible that an adjustment of the first distance is transmitted directly to the outlet arrangement, so that no double adjustment of the corresponding distances to the respective product to be separated is necessary.

A particularly simple embodiment of such a coupling can be achieved, for example, by a push rod.

In order to achieve a further simplification of the troubleshooting, especially in a transfer area between the separating arrangement and the outlet arrangement, it makes sense if the upper outlet extension is configured hinged.

A hinged configuration of the upper outlet extension can be achieved, for example, by the fact that the upper outlet extension is driven and supported by a drive arm pivotally mounted at both ends about parallel axes. In this way, the upper spout extension to pivoted this drive arm and, for example, forward, ie in the transport direction, are folded down, so that the transfer area between separation arrangement and drive assembly is released for fault elimination.

On the drive arm can also be provided on the drive side a stop for determining a maximum rotation of the drive arm relative to the coupling. In this way it is achieved that an on the coupling passed on change of the first distance on the stop and the drive arm also acts on the upper Auslaufverlängerung and so the second distance is adjusted accordingly.

In order to ensure a basic setting of the second distance, it makes sense if the stop is designed to be adjustable. In this way, for example, a predetermined minimum distance can be set, which can not be fallen below.

In addition to the first stop, there may also be provided a second variable stop for adjusting parallelism between the upper spout extension and the lower spout extension. In this way it is achieved that the upper outlet extension does not rest on the lower outlet extension and is raised only by the transported between the outlet extensions products, but that a constant distance can be adjusted.

In order to ensure increased flexibility of the band applicator according to the invention, the outlet device can also be designed to be pivotable perpendicular to the transport direction, ie vertically. In this way, the so-called outlet angle, under which the isolated products emerge from the belt feeder, are set.

All provided as a separation or outlet conveyor belts can be designed as so-called. Friction belts, friction suction belts or tunnel belts.

The present invention will be explained below with reference to an embodiment with reference to the accompanying figures.

FIG. 1 shows a perspective view of a tape feeder 1 according to the invention obliquely from the front.

The belt feeder 1 has as essential components a separating arrangement 5 and in the transport direction according to the Separation arrangement arranged outlet arrangement 7. Products to be separated are supplied to the separating arrangement 5 via a so-called round bar magazine 23 consisting of a stacking plate 25, two lateral guide plates 24 and round bars arranged on the front side for retaining the products. A product lying at the bottom in a stack of products to be separated comes into contact with the separating belts 50 running in parallel and the separating rollers 51 arranged corresponding to the separating belts 50 and is extracted therefrom from the product stack and fed to the outlet arrangement 7.

The outlet arrangement 7 consists essentially of a lower outlet extension 71 and an upper outlet extension 70, each having parallel running, aligned in the transport direction and counter-driven discharge belts 72, 73 have. In the present embodiment, two upper outlet bands 72 and at the lower outlet extension 71 four lower outlet bands 73 are provided on the upper outlet extension. The outlet belts 72, 73 are driven on the outlet extensions 70, 71 via drive rollers located in the rear in the transport direction, which are connected to the drive via respectively associated drive shafts, and are supported in the transport direction on the front via deflection rollers.

Advantageously, the drive rollers for the discharge belts 72, 73 for the upper Auslaufverlängerung 70 and the lower Auslaufverlängerung 71 on an identical circumference and are driven by a toothed belt 32 of the drive at the same speed and in opposite directions. In this way it is ensured that a product located between the outlet extensions 70, 71 uniformly in the direction of Transporting direction T between the outlet extensions 70, 71 is transported.

All components of the band feeder 1 are arranged on a laterally arranged base plate 9. This base plate 9 is pivotally mounted about a pivot axis A on a fastening device 11 which is formed in the present embodiment as a mounting foot. By a pivoting of the band feeder 1, for example, an inclination of the separating arrangement 5 can be adjusted relative to the horizontal, so that depending on the properties of the products to be separated an additional force in the direction of transport direction T can be achieved.

In order to achieve a reliable separation of the products located in the round rod magazine 23, it is necessary to set a first distance d1 between the separating rollers 51 and the separating bands 50 as exactly as possible and coordinated with the products to be singulated. A particularly good adjustability of this first distance d1 is achieved in that the separating belts 50, which are aligned in the transport direction T front and back on guide rollers, run in the area between these guide rollers on a separating plate 52. This separating plate 52, on which the separating belts 50 lie, in particular in the region in which the separating rollers 51 are arranged, a defined first distance d1 between the underside of the separating rollers 51 and the separating belts 50 is achieved, which is largely independent of a tension and independent can be adjusted by a weight on the separating belts 50.

An adjustment of this first distance d1 is effected by means of so-called millimeter screws 41 which act via ball-and-socket joint shafts 42 on an adjustment arrangement 4. The millimeter screws 41 are attached to ensure correct alignment with a cross member 40 arranged orthogonally to the base plate 9.

A rotation on the millimeter screws 41 acts on the ball joint shafts 42 on the adjustment assembly 4, which is formed pivotable in the present embodiment. The separating rollers 51 and one of the separating rollers 51 driving shaft is pivotally mounted on the adjusting assembly 4 via a pivot assembly 6. The swivel assembly 6 is fixed to the adjustment assembly 4 via a fixing assembly 8, which is formed in the present embodiment as an index pin 8 in a defined position. The index pin 8 are formed as a tapered index pin and thus ensure an exact alignment of the pivot assembly 6 to the adjustment 4.

By this two-part design, it is possible that on the one hand on the millimeter screws 41 an exact adjustment of a distance of the separating rollers 51 is made to the separating belts 50 and on the other hand pivoted by loosening the index pin 8, the pivot assembly 6 of the adjustment assembly 4 and thus the distance between the Separation rollers 51 and the separating belts 50 can be increased. In this way, it is particularly easy to remove disturbances, for example obliquely or multiply retracted products, in the region of the separating arrangement 5.

In order to facilitate a pivoting of the pivot assembly 6 of the adjustment assembly 4, a handle 61 for lifting the pivot assembly 6 together with the separating rollers 51 is provided on the pivot assembly 6 side.

In FIG. 2 is the band investor off FIG. 1 shown in a slightly rotated perspective view.

In the illustration in FIG. 2 is particularly clear that the base plate 9 is used for storage of all driven shafts and all attachments. The drive 3 is driven by a motor 30, which is arranged in the present embodiment below the separating plate. A drive axle of the motor 30 is arranged in extension of the pivot axis A and acts on a toothed belt 32 driving the various shafts of the belt feeder 1.

How out FIG. 2 can be seen, the base plate 9 is arranged via a flange 12 on the mounting assembly 11 and fixed by a clamping device 13 in position relative to the mounting arrangement. A change in the angle of inclination of the Bandanlegers 1 relative to the mounting assembly 11 can be done by loosening a screw of the clamping assembly 13 and by pivoting the Bandanlegers 1 about the pivot axis A.

In FIG. 2 It can also be seen that a distance between the upper outlet extension 70 and the lower outlet extension 71 by an adjustable stop 78, which is arranged between the outlet extensions 70, 71, can be fixed. By the stop 78 can be avoided so that the upper outlet straps 72 on the lower outlet extension 71 rest and so a higher wear of the outlet tapes arises.

FIG. 3 shows a longitudinal section through the belt feeder 1 from the FIGS. 1 and 2 parallel to the base plate 9.

In the sectional view from FIG. 3 is particularly well to recognize the function of the tape feeder 1 according to the invention. Products to be separated are stacked in the round bar magazine 23, ie in the present representation between the stacking plate 25 and the separating rollers 51, inserted. A product lying in the bottom of the stack is detected by the separating belts 50 and the separating rollers 51 and, due to the counter-rotating run of the separating belts 50 and the separating rollers 51, transported between them in the direction of the outlet arrangement 7. In the outlet arrangement 7, the product extracted from the stack is moved further between the outlet belts 72, 73 in the transport direction T and, for example, output at the end of the outlet extensions 70, 71 into a downstream processing process.

Characterized in that the separating plate 52 is arranged directly below the separating rollers 51, the first distance d1 between the underside of the separating rollers 51 and the separating belts 50, which run over the separating plate 52, can be set particularly accurately. Operation of the millimeter screws 41 causes an extension or shortening of the distance between the millimeter screw 41 arranged on the crossbar 40 and the adjusting arrangement 4 connected to the millimeter screw 41 via the ball joint shaft 42. The adjusting arrangement 4 is arranged pivotably such that a change in the distance between the millimeter screw 41 and the adjusting assembly 4 a Changing the first distance d1 between the separating rollers 51 and the separating belts 50 causes. The separating rollers 51 are, as already described, via the pivot assembly 6 which is fixed by means of the index pin 8 on the adjusting assembly 4, releasably connected thereto. By loosening the index pin 8, it is possible to fold the separating rollers 51 of the separating belts 50 and thus eliminate disturbances in this area comfortably.

FIG. 3 also shows that the upper spout extension 70 is driven by a double pivotally mounted drive arm 20. An arranged in the pivot arm 20 drive belt acts at one end on the rear in the direction of transport roller 75 of the upper outlet extension 70, thus driving the upper outlet belts 72 and the other end is articulated via the drive, so that a synchronization of the upper and lower discharge belts 72, 73 is ensured. Due to the double pivoting articulation of the upper outlet extension 70, it is possible to lift them in the rear area and unfold over the pivot arm 20 to the front, so that disturbances in a transfer area between the separating arrangement 5 and the outlet arrangement 7 can be eliminated in a simple manner.

Via a push rod 15 and an adjustable stop 21 of the drive arm 20 is also connected to the adjustment assembly 4, so that an adjustment of the first distance d1 between the separating rollers 51 and the separating belts 50 at the same time setting a second distance between the upper outlet extension 70 and the separating belts 50th or the lower outlet extension 71 causes.

In FIG. 3 In addition, it is particularly easy to see the pivotable mounting of the band feeder 1 on the base plate 9 on the mounting assembly 11. In the present illustration, the motor sitting on the pivot axis A or main drive shaft is omitted for reasons of clarity, so that the pivot axis A is particularly well recognizable by the circular configuration of the flange 12, with which the base plate 9 and the mounting assembly 11 are connected.

FIG. 4 shows the band feeder 1 from the FIGS. 1 to 3 in a perspective view from the rear, wherein the round rod magazine 23 and some of the base plate 9 oppositely disposed attachments are not shown for reasons of clarity.

In this representation, it can be seen particularly clearly how the millimeter screws 41 act via the ball joint shafts 42 on the setting arrangement 4, with which the pivoting arrangement 6 is connected via the index bolts 8. In this illustration, the Abschwenkbarkeit the separating rollers 51 by means of the pivot assembly 6 after a release of the index pin 8 is also particularly easy to recognize.

The index pins 8 are designed as conical index pins, so that a precise alignment of the pivot assembly 6 is ensured to the adjustment assembly 4.

A basic tension of the separating belts 50 is adjustable via a shaft 54 arranged on the separating plate 52 in the transport direction at the rear, wherein guide rollers 54 for guiding the separating belts 50 are provided on the shaft 54. A distance of the shaft 54 to the separating plate 52 in Transport direction T is adjustable by threaded rods, via which the shaft 54 is mounted on the separating plate 52, so that the separating belt 50 can be operated under optimal bias. The singling belts 50 are preferably designed as toothed belts, so that a very good drive capability can be achieved even without a very large preload and the associated increased friction.

FIG. 5 Finally, shows an enlarged view of the upper spout extension 70 and the double-rotatably mounted drive arm 20, which drives the upper outlet belts 72 of the upper spout extension 70. The upper discharge belts 72 are driven by two drive rollers 75 on the drive shaft of the upper discharge extension 70 located in the transport direction T at the rear. A coupling of the driving force via the drive arm 20, wherein in the interior of the drive arm 20, a circumferential belt for implementing the movement of the driven shaft 22 is arranged on the rollers 75. In FIG. 5 is also good to recognize the stop 21, which prevents a drop in the rear end of the upper outlet extension 70 beyond the stop 21 addition.

In order to detect or adjust a distance in the direction of transport T between individual products transported by the outlet arrangement 7, a photocell 80 is also provided on the upper outlet arrangement 70, which detects the passage of the individual products and thus for control and / or regulation can be used.
