Description

technical background

The The present invention relates generally to conveyor systems which include a plurality of Power-driven conveyor sections and in particular devices for changing the effective length of the System by controlling the deflection of transported goods from a conveyor section to another.

Lots conveyor applications require that goods, which on a conveyor belt promoted be transferred to another conveyor belt, which can run in a different direction, such as the opposite Direction. For this purpose will be common stationary Rails, which are the conveying surfaces of the bands to span at a transfer point, used. In some applications, such as the collection of goods, can the transfer point to be moved. The mobile transfer point allows it, the effective length the conveyor line and consequently control the amount of goods collected. In a spiral collector, such as that shown in U.S. Patent No. 6,152,291 two parallel conveyor belts - one feeding Band and a laxative Band - arranged helically, wherein a rotatable transfer device between these runs. The position of the transfer device depends on the relative speeds of the two opposite running bands from. A guide plate on the transfer device steers goods from the feeder conveyor belt on the laxative Conveyor belt. A rotatable element in the transfer device engages at the same time with drivers in each other, which at the feeder and the laxative band are formed, which are specially designed. The rotatable element, which is driven by the drivers, shifts the transfer device and their attached guide plate along the bands as determined by their relative Speeds. The rotatable element runs together with the transfer device along.

One commoner Collection system is as bi-di-table (bi-directional table) known.

typically, For example, a bi-di table comprises a bi-directional conveyor belt arranged in such a way is that this runs perpendicular to a main conveyor belt. When goods are on the main conveyor belt damming, the back pressure directs this on the bi-di band, which in one of the main conveyor running direction. In this way goods become on the surface of the bi-di band collected. If downstream operations require more goods, the direction of the bi-di-band is reversed, so that the collected Goods back to that Main conveyor belt packed become. These bi-di tables containing the bi-di-band and its drive devices store, generally have a rectangular shape, wherein Drive or idle shafts for sprockets or Rollers are located at each end. Unlike the spiral collector however, in these simple, ubiquitous tables, the order of entry is not the starting order.

Consequently there is a particular need for a collection system, wherein the input order is the output order (first-in / first-out), in particular on one, which can be easily retrofitted in a bi-di table can. More generally, there is a need for one simple device for diverting goods from a conveyor belt on another, such as on opposite conveyor belts.

A device for controlling the transfer of goods between oppositely-running conveyors is by the US 6,182,812 B1 known. The conveyors extend substantially side by side and in parallel at a constant distance from each other. A movable transport means is disposed in the distance formed by the conveyors and includes a bridge which extends over the distance between the conveyors. The means of transport is driven by the two conveyors so that it moves linearly between the conveyors. The speed of the means of transport depends on the speed difference of the two conveyors. The distance between the two conveyors can sometimes cause difficulty in transferring the goods from one conveyor to the other.

Summary

These and other needs are met by a new goods diverter embodying features of the invention. In the apparatus, a first conveyor belt is operated at a first speed in a first direction. A second conveyor belt is operated at a second speed in another second direction, typically the opposite direction. A flow of goods is conveyed along a conveying surface of the first conveyor. A carrier travels along a path in a generally parallel pattern to the first and second conveyor belts. A diverter attached to the carrier extends at least over a portion of the conveying surfaces of the first and second bands to redirect goods in the stream from the first band to the second band. The carrier is driven by a differential drive device at a speed which depends on the speeds of the first and second speeds the second conveyor belt, controlled. In this way, the position of the diverter, and therefore the transfer point, are determined by the relative speeds of the two belts.

at One version of the device is the differential drive device stationary attached to a framework which supports and the first and the second band are stored. In another version the differential drive device is not directly on the first one and the second band, but on a first drive device, which the first belt drives, and on a second drive device, which drives the second volume. This makes it possible, not custom, less expensive normal bands to use as first and second volume.

at a collector, wherein the input order is the output order is (first-in / first-out), which is the device of the invention used, becomes a goods flow at a position in the feed direction on a main conveyor to the first or supplying conveyor belt passed, transferred by the deflecting element on a carrier to the second or laxative conveyor belt and then at a location in the flow direction through the second band back to the main conveyor directed. The amount of collection is determined by the carrier drive device, which the carrier and the deflector along the feeding and discharging Dependent on bands positioned by their relative speeds.

In other versions, the carrier is an endless carrier belt parallel to the first and second belts. The band may be an intermediate band between and abutting the first and second bands having a transfer surface portion over which products are transferred from the first band to the second band. Alternatively, the carrier tape flanks the first conveyor belt and carries the attached deflecting element. The flanking band can be used in conjunction with another flanking band on the opposite side of the second conveyor, which allows two-sided support for the deflector. In this version, the first and second conveyor belts may be disposed abutting one another for direct transfer of goods. The belts and the carrier are controlled by a control device that individually controls the driving devices of the first and second conveyor belts and the carrier. In each of these examples, the drive characteristics for different applications may be tuned by setting the speed of the carrier to as ₁ -bs ₂ , where s _{1 is} the speed of the first conveyor, s _{2 is} the speed of the second conveyor, and a and b adjustable parameters are, which are chosen to suit the application.

Consequently The device offers clear advantages when diverting goods from on a conveyor belt a parallel, oppositely moving conveyor belt.

Precise description

A device for diverting goods from a flow of goods is in 1 and 2 shown. The device comprises a conveyor bed which is supported by a frame 20 with legs 21 and a pair of parallel upper support rails 22 is trained. crossbars 23 clamp the support rails at opposite ends 24 . 25 of the conveyor bed. cross supports 26 , which form part of the frame, store a conveyor trough or wear strips 27 , which is the conveyor track of a first feeding conveyor 28 and a parallel second laxative conveyor 30 are underlaid.

Each conveyor comprises an endless belt or strings at the first and second ends 24, 25 about rotating arrangements 32 . 33 is wound. The belt or chain is preferably a modular plastic endless belt, such as any plain belts manufactured and sold by Intralox, Inc., Harahan, Louisiana, USA. Modular conveyor belts are beneficial because the modules can be easily connected one behind the other and side by side with pivot pins, typically in a brickwall pattern, to produce belts of almost any length and width. However, any tape can be effectively used, including, for example, metal chains or cloth tapes. The feeding band 28 and the laxative band 30 become in the direction of the arrows 34 . 36 operated.

In the example of 1 and 2 The feeding belt 28 is driven by a first feeding drive device 38 driven, which are part of the second rotating arrangements 33 is. The laxative belt 30 is driven by a second exhaust drive device 40 driven, which are part of the first rotating arrangements 32 is. In this drive arrangement, the first and second driving devices pull the belts in tension along the conveying path of the conveyor in the direction of the arrows 34 . 36 , Engines 42 , preferably variable speed motors, in the feed and discharge drive devices, rotate the rotating assemblies which interlock by projections or by friction with the belts to drive the belts in the directions shown.

The device further comprises a deflecting element 44 which extends over at least a portion of the width of the first and second conveyors. The deflecting element is attached to a carrier, in this example an intermediate band 46 which is in the room 48 is arranged between the feeding and the discharging band. The intermediate belt is preferably a modular plastic conveyor belt, but may also be a metal chain or a fabric belt. In 1 and 2 only a portion of the intermediate belt is shown to illustrate the features of the device, however, the intermediate belt is in line therewith coincident with the infeed and outfeed belts, and this is also an endless belt which surrounds the first and second rotating assemblies 32 . 33 is wound. The intermediate band, which is arranged between the feeding and the discharging band, is arranged with only a minimum gap to each of them abutting. Side rails for holding goods on the conveyor are not shown to simplify the illustration.

The deflecting element 44 captures goods 50 from a flow of goods on the feeding belt 28 and steers them over a transfer area 52 of the intermediate band on the laxative band 30 which runs in the opposite direction. The deflecting element has a guide surface 54 in, in this example, a curved surface extending from a base 56 up stands. The base is attached to a portion of the intermediate belt so that the deflector moves with the intermediate belt. poor 60 . 61 of the deflecting extend at least over a portion of the conveying surfaces of the feeding and the discharging belt.

In the version, which in 1 and 2 is shown, the first arm extends 60 over most of the width of the feeding tape. In this case, all of the goods 50 taken in the stream through the deflecting element. However, it is also possible to use a shorter first arm which grips some goods but lets others through. The arms may rest directly on the infeed and outfeed conveyors, or they may be located above the conveying surfaces, as long as they are not so high that goods to be deflected pass through under normal operation. There is also a barrier 62 attached to the intermediate band. The baffle of the deflector and the barrier define the transfer surface 52 of the intermediate band. The barrier ensures that products are only diverted over the transfer area and not at other points along the conveyor track. For a sliding transfer of products, the conveying surfaces of the feeding and discharging bands are preferably coplanar with the outer surface of the intermediate band. It would also be possible, as in 3 illustrated that the conveying surfaces of the feeding conveyor belt 28 and the laxative conveyor belt 30 and the outer surface of the intermediate band 46 from the feeding tape the laxative band are arranged graduated in decreasing height. Alternatively, the entire conveyor bed may be inclined downwardly from the horizontal to the outgoing belt to provide the assistance of gravity in clearing goods from the transfer surface.

In the exemplary version of the device incorporated in 1 and 2 are shown are the rotating arrangements 32 at the first end 24 the conveyor bed closer in 4 shown. A first rotating arrangement 64 and a second rotating assembly 65 are coaxially arranged and terminate in a differential drive device 66 , The first rotating assembly drives the laxative band 30 active. The arrangement is stationary on the crossbar 23 appropriate. The arrangement comprises the drive motor 42 , which in this example a right angle drive shaft 68 having. The first rotating assembly comprises a shaft 69 , which is shown segmented, on which sprockets 70 are attached. bearing blocks 72 store the waves for rotation. The number of required bearing blocks, sprockets and shaft segments depends on the width of the belt and its load. In this example, four sprockets, three bearing blocks and two shaft segments for the first rotating assembly are shown. The sprocket shaft 69 is with the motor drive shaft 68 through a sleeve 74 connected. The other end of the sprocket shaft is a differential shaft 76 ( 5 ) through a sleeve 77 connected. The sprockets have circumferentially arranged teeth which are in 4 are shown as elevated portion to simplify the drawing, and which engage with a receiving structure at the bottom in the discharging band or the laxative chain to drive and track this. In the case of a fabric belt, the toothed sprockets are replaced by rollers which frictionally drive the belt.

While the first rotating arrangement 64 forming at the first end of the belt a driving device for the laxative belt is the second rotating assembly 65 an idler arrangement for the feeding tape 28 ,

In this version of the device, the feeding conveyor drive device is in the rotating assemblies 33 at the other end 25 the conveyor bed arranged in a stationary manner. Although this arrangement is favorable, since both drive devices pull the belts, the drives can be distributed at the same end or, especially for long belts, along the length of the belts. The idle arrangement 65 is the same as the first rotating arrangement 64 , but is not directly connected to a motor. It is, however, through a sleeve 77 connected to the differential drive device. Thus, the differential drive device is connected to each rotating assembly which rotates at a speed corresponding to the speed of the associated belt. Each rotary assembly, whether it comprises a drive shaft or an idler shaft, acts as an input drive device for the differential drive device.

The differential drive device is in 5 shown in more detail. The device comprises four bevel gears 78A - D. The differential shaft 76 , which rotates with the speed of the discharge conveyor, is with the bevel gear 78A connected. The differential shaft 76 ' , which rotates with the speed of the feeding conveyor belt, is with the opposite bevel gear 78B connected. The bevel gears grip with bevel gears 78C and 78D into each other, which coaxially and axially as a pinion on a pinion shaft 80 arranged in line. Clutches 82 Keep the bevel gears on the shafts and the pinion shaft in place. The ends of the pinion shaft run from a turnstile 83 starting, which also has a storage for the differential shafts 76 . 76 '' supplies. The differential gear is in a cavity 84 inserted, which in the middle of two assembled middle housing halves 86 is trained. The ends of the pinion shaft are in cavities 88 inserted, which are formed in the radial direction in the housing halves.

metal plates 89 serve as thrust bearings. dowels 90 fit the two housing halves, which conventionally by bolts or screws, which through holes 92 run, be held together. A toothed sprocket 94 is attached to each half of the housing. The peripheral teeth of the sprocket engage with the intermediate band 46 into each other to power this.

The differential gear conventionally acts such that a relative movement of the shaft driven bevel gears 78A and 78B causes the pinions 78C and 78D around the axis of the differential shafts 76 . 76 '' rotate. As the pinions rotate, the ends of the pinion shaft cause it 80 in that the housing and the sprockets rotate. The speed of rotation depends on the relative speeds of rotation of the output shaft bevel gears. In the situation where the evacuating belt and the feeding belt are moving in opposite directions at the same speed, the exhaust driven wheel rotates 76 at a certain speed in one direction, and the feed driven bevel gear 76 '' rotates at the same speed in the opposite direction, causing the pinion assembly to rest immovably with its pinion shaft. If one of the conveyor belts accelerates relative to the other, the differential drive mechanism causes the housing and sprocket assembly to rotate in the direction of the faster rotating assembly, but at half the difference between the speeds of each rotating assembly. Thus, in this example, the velocity s of the intermediate band is given by s = ½ (s ₁ -s ₂ ); where s _{1 is} the speed of the faster moving band and s _{2 is} the speed of the slower moving band. Of course, the ratios may be changed through the use of reduction devices or other conventional techniques to derive other velocity relationships, which may be generally defined by s being proportional to as ₁ -bs ₂ , where a and b are parameters represented by, for example, FIG effective gear ratios. This makes it possible, in specific applications, to operate the intermediate belt at a speed which is influenced by one of the conveyor belts relatively more than by the other.

The second rotating arrangements 33 , which at the second end 25 of the conveyor bed are stationarily similar to those on the first with the following difference, which in 6 is shown. First, the drive motor 42 for the feeding tape and its drive elements 96 at the crossbar 23 attached to this end. Second, make idle elements 98 the rotating arrangement for the feüh-generating band. Third, the rotating elements, although coaxially mounted, do not drive a differential gear at this end. Instead, there is an idle sprocket 100 on an idle shaft 102 , which by flanking bearing blocks 72 is stored, provided to the endless intermediate belt 46 store and track at this end of the conveyor bed.

Another version of a device for redirecting goods is in 7 shown. In this version, the afferent band is 28 and the laxative band 30 arranged abutting one another. The deflecting element 44 ' is through a carrier tape 104 which is closest to the feeding tape in this example. The deflector extends through a gap between stationary side rails 106 via the conveyor surfaces of the infeed and outfeed belts to direct goods from the first belt directly to the opposite running second belt without having to cross an intermediate belt, which is a distinct advantage. The drive devices of each of the conveyor belts drive the carrier belt differentially.

by virtue of the fact that the carrier tape in this version is not located next to the laxative band, For example, the drive device of the laxative belt must be arranged by an interposed Intermediate shaft or another conventional connection with the Differential drive device of the carrier band can be connected.

A slightly modified alternative to the device in 7 is in 8th shown. In this version, a deflecting element 44 '' at each end by a carrier tape 104 carried. This version provides better storage for the deflector. The two flanking carrier bands are each driven differentially uniformly.

The Previously described versions are especially for retrofitting in existing bi-di tables, which are typically sprockets, shafts and provide motors at each end and a strip bearing structure along the conveyor track and the return path include. In essence, the bi-di-band and its drive and idler sprocket assemblies through the belts and rotating assemblies replaced the invention. The rest of the bi-di-conveyor bed remains largely unchanged. As already mentioned, The versions described are suitable for a simple size extension by widening or lengthening the bands.

Heretofore, the carrier for the deflector has been described as a belt (an intermediate belt or a carrier belt) which is differentially driven by a differential driving device connected to driving devices of the feeding and discharging belts. In other versions of the device, which in 9 and 10 are shown, the deflecting element 44 on a carrier 106 worn, which is the linearly adjustable threaded ring of a lead screw 108 is. The lead screw is at one end with a stationary differential gear 110 and at the other with a fixed bearing block 112 connected at the opposite end of the support run. The speed and direction of rotation of the lead screw depend on the relative speeds of the feeding tape 28 and the laxative band 30 from. As the lead screw rotates, the carrier is driven along the travel path thereof. To minimize the space between the two conveyor belts, the deflector is a thin but strong rib 114 connected to the carrier, which is attached by welding to each of these, for example.

All of these Umlenkvorrichtungsträgeranordnungen can be used to redirect goods from one conveyor to another and are for example in a collector, wherein the input order is the output order, such as the one in 11 presented, useful. The collector system 116 effectively adjusts the length of a conveyor line depending on the supply of goods in the feed direction and the demand in the flow direction.

A stream of goods 50 , which by a main conveyor 120 in the direction of the arrow 118 will be transported at one place 122 of the main conveyor in the feed direction by a feeding conveyor belt 28 taken in the direction of the arrow 34 is operated. A feeder guide rail 124 directs the flow of goods to the feeding belt. As the feeding belt transports the goods, they pass through the diverter 44 , which on the intermediate band 46 is attached and carried by this, recorded and deflected. The goods cross the transfer area 52 the intermediate band between the deflecting element and the barrier 62 and arrive at the laxative conveyor belt 30 , The diverted goods are at one place 128 in the direction of flow through the laxative conveyor belt, which is operated in the direction of the main conveyor towards, transferred to the main conveyor. An exhaust guide rail 125 directs the flow of goods back to the main conveyor. A transfer plate 126 , such as a shelf, is used for sliding transfer of the goods to and from the main conveyor. The main conveyor may alternatively use other transfer techniques such as transfer belt edges which are attached to and move with the main conveyor belt.

The feeding and the laxative Band need not run perpendicular to the sponsor, but can for example, run parallel to a main conveyor, which segments in the inlet direction and flow direction on opposite sides of the unit the feeding / discharging tapes. The collector allows it that the carriage of goods along the main conveyor in terms of mismatches between the supply of goods tuned in the direction of supply and the need for goods in the flow direction becomes. The collector does this by controlling the effective length of the Conveyor line. If the goods supply increases, the feeding becomes Band with a higher Speed as the laxative Band operated. The differentially driven carrier belt moves away from the main conveyor continued. If the deflector further away from the main conveyor is, can more goods on the extended conveyor line accumulate. When the goods need in the flow direction to a level that exceeds the goods supply, the laxative promoter gets faster as the afferent promoter operated. When this happens, the carrier tape will move and its deflection on the main conveyor and shorten the effective conveyor line and the proportional collection area. To protect limit switches (not shown) at each end of the storage bed of the supplying / discharging conveyor, that the motors stop when the deflector has one end of it permissible Area reached along the conveyor storage bed.

The supply of goods and the need for them can be achieved by conventional goods sensors 130 are detected, which are arranged, for example, at locations in the inlet direction and flow direction on the main conveyor. Their signals 132 . 133 become electrically a control device 134 which further control signals 136 . 137 to the drive motors 42 sends at variable speed to adjust the speeds of the feeding and discharging bands.

Although the differential drive devices described so far are mechanically coupled differential gears, it is alternatively possible to use an independent drive for the carrier, wherein the differential speed is calculated by the control device and an appropriate speed control signal is sent to the differential drive device of the carrier. With such an arrangement, the controller adjusts the speed relationship (eg, s = as ₁ -bs ₂ ) to the needs of the system at all times. An operator sets the values of the parameters a and b by the control device.

Consequently For example, the invention has been exemplified in terms of various versions described. Nevertheless, it is for Specialists will see that other versions are possible without significant to deviate from the new principle and advantages of the invention. For example, the carrier on an arrangement of rack and pinion, an arrangement of Cable and drum or an arrangement of pull chain and rail to run. As another example a plurality of intermediate drive devices comprising a plurality of differential gears include, along the conveyor be distributed, especially for long ribbons. The bands can curve enabled, laterally flexible bands which are along a curved Railway are arranged. The differential can be with spur gears or other types of wheels are realized.
