Collective order device

The invention relates to a conveyor device, which is under the name Collector for articles or items is known and in which the items in batches, in orderly groups or any rows that form an arbitrary mass at the input end of the device. The collective sponsors are operated in such a way that they output the input of the parts in the form of a single stream.

Article collecting devices have a wide range of applications in breweries, when filling bottles and in other industrial areas in which individual parts or articles, such as bottles and can filling and other work machines in a single stream

are to be entered. If the article entry is incorrect and is taken without interruption. can improve the profitability of the plant suffer from it.

In conveyor systems of this design, the individual parts or _{; V} articles have a tendency to jam or form a bridge over the conveyor, which prevents the flow of articles.

borrowed

The articles occasionally fall over or tip over on the conveyor and enlarge consequently, the likelihood of deadlock.

The efforts to avoid the formation of jams or the creation of bridges / upright articles have led to certain successes guided; however, the problem of fallen items remained. It is usually necessary to manually erect objects or articles that have fallen over or to remove them from the collecting conveyor. As a result of the relatively high speed of conveyor systems of this type and as a result of the relatively high speed of the flow of articles, one or more Overturned articles caused jam become so large within a short time that the production system upstream of the collecting conveyor must be switched off. As long as the traffic jam isn't is quickly remedied, a speed reduction in production or an interruption in production downwards must be required of the traffic jam due to missing articles.

Based on this, the object of the invention is to provide a collector to train ördergerät so that the fallen articles are automatically removed to avoid the adverse effects of fallen over To avoid articles with regard to the production line or the production line.

The collecting conveyor according to the invention comprises a pair of endless conveyors, which side by side on a suitable frame

-3- 309843/0580

are arranged. The upper side of the conveyor, i.e. the upper run represents the article-bearing surface located on a common plane. One of the conveyors is an input or input conveyor while the other conveyor is effective as an exit or exit conveyor. A first lateral guide rail extends diagonally with respect to the infeed conveyor with the downstream end to the outfeed conveyor adjoins. A second lateral guide rail is arranged opposite the first lateral guide rail and extends look diagonally across the discharge conveyor, upward lying end is adjacent to the input conveyor. The side guide rails together form a converging collecting track for receiving articles in an arbitrary quantity distribution at the upstream end of the input conveyor to these articles or objects as a single stream downstream to be discharged at the delivery conveyor. The corresponding side guide rails are carried on the frame and are located together with their supports above the surfaces of the conveyor carrying the articles. The distance between the guide rails is designed so that that fallen articles are removed from the collecting track under the corresponding guide rails and their holders.

The invention is based on an exemplary embodiment with reference Explained on the accompanying drawings.

The conveyor 1 shown in the drawings, which is used to collect or combine articles, is particularly suitable for Transport of bottles 2 and consists of an input conveyor 3 and a delivery or output conveyor 4. These two Conveyors are aligned laterally to one another and are held on a suitable frame 5. The upper run of the endless chain conveyor 3 and 4 have the same height and form the article-bearing surfaces 6 and 7 around objects, such as bottles to move between a pair of fixed, lateral guide rails 8 and 9. The guide rails 8 and 9 form a convertible

™ ο "™

Yawing or funnel-shaped path to collect the individual articles and deliver them in a single stream.

To achieve the best possible performance with continuous production the sponsor must 1 the article 2 in an orderly manner and

ever
without interruptions / according to the work needs of the associated work machines (not shown). Since the delivery conveyor 4 is designed for individual delivery, it can be relatively narrow and must be able to run at a relatively high speed. The input conveyor 3 is used to transport a water flow of articles 2 from one or more preceding working machines (not shown) and / or to pick up articles from a collecting table (not shown). For this reason, the input conveyor 3 is wider than the conveyor 4 and works at a slower speed.

The lateral guide rail 8 extends diagonally over the input conveyor 3, the movement downwards with respect to the conveying flow lying end of the guide rail 8 close to the delivery conveyor 4 ends. From the upstream end of the guide rail a rail extension 10 extends upwardly and follows the corresponding outer edge of the input conveyor 3 to limit the flow of items 2 along that side of the conveyor. The lateral guide rail 9 is / is laterally offset to the guide rail 8 and extends diagonally over the delivery or output conveyor 4. The upward movement The end of the rail 9 located is adjacent to the edge of the input conveyor 3. A rail extension 11 extends

309843/0580

opposite the rail extension 10 from the upward movement lying end of the guide rail 9. So form the lateral guide rails 8 and 9 with their corresponding extensions 10 and 11 a path of movement for the articles 2. The path is relatively wide and moving upward on the input conveyor 3 narrows into a relatively narrow section downstream of the output conveyor 4.

The rail extensions 10 and 11 can consist of a pair of vertically spaced rods, as shown in FIG The lower edge of the rail extensions 10 and 11 is at a distance above the article bearing surface 6 of the input conveyor 3, which is less than the diameter of the article 2. The rail extensions are as a result, relatively deeply in contact with the articles movable along the rails.

The side extending diagonally over the input conveyor 3 Guide rail 8 has a number of rollers or wheels 12 provided, which are rotatably mounted on shafts 13 extending vertically. The shafts 13 are between vertical im

/ 7

Spaced, overlapping strips 14 and 15 attached. The shafts 13 are in one common vertical plane and have the same distance from one another along the lateral guide rail 8. Every wave 13 is used to support a plurality of vertically spaced rollers 12 between the opposite ones Bars 14 and 15. The rolls of adjacent shafts are vertical

309843/0580

offset to one another, - as shown in FIGS. 2 and 3 can be found. The wheels or rollers 12 of the guide rail 8 give the bottles 2 a certain vibration when the bottles are moved in contact with the wheels of successive shafts 13 along the guide rail 8 of the input conveyor. Any tendency towards the formation of bridges or wedges due to two or more bottles laterally aligned between the guide rails 8 and 9 is consequently prevented. The rollers 12 are preferably made ^; made of nylon or of another suitable plastic material in order to oppose the article 2 with a relatively small frictional resistance when moving along the guide rail.

The lateral guide rail 9 is preferably dumbbell-shaped in cross section, with the opposite, widened Parts align vertically. As a result, the articles 2 rest on two points that are vertically spaced from one another the guide rail 9 when they are moved along this rail. There will be a relatively low frictional resistance opposed to the individual objects or articles. In order to further reduce the frictional resistance on the articles 2 is the Guide rail preferably made of high density polyethylene or some other suitable plastic material.

The side guide rails 8 and 9 are ι-zuein at spaced points on the other located on the frame 5 is mounted and located vertically above the corresponding j, load-bearing, the item \

the hooks 6 and 7 of the conveyors 3 and 4. The distance is so '

309843/0580

chooses that he at least the diameter of the article or bottle 2 exceeds. Thus, the lateral guide rails 8 and 9 are relative to the articles 2 which can be moved along them set high.

The individual supports for the guide rail 8 each include a frame strut 16 attached to the frame 5 and one with the Rail connected rail strut 17. The frame strut 16 and the rail strut 17 extend over the edge of the input conveyor 3 to the outside and are connected with the aid of a spacer body 18. The spacer body 18 is laterally at a distance arranged to the outer edge of the input conveyor, which exceeds at least the diameter of the article 2. According to FIGS. and 3 change the corresponding rail struts 17 in FIG their length according to the adaptation to the diagonal guide rail 8. The rail struts 17 are at a distance above of the article-carrying surface 6 of the input conveyor 3, the distance being at least the diameter of the article 2 exceeds.

If articles or objects, so bottles 2 are aligned in an arbitrary quantity distribution on a moving conveyor are, they have a certain instability, which is why one or more bottles occasionally fall over or on one Flip side. When bottles 2 fall upstream of the guide rails 8 and 9 onto the conveyor, they stop moving with the upright bottles and between the opposing, relatively narrow rail extensions

309843/0580

10 and 11 continued. Overturned bottles covering the area Reach between the guide rails 8 and 9 and the bottles falling over in this area of the collecting conveyor 1 are under released the relatively high guide rails. The overturned bottles either put their deposit on the input conveyor 3 maintenance) of the guide rail 8 or the pressure of the collecting, upright bottles pushes the fallen bottles Bottles out of the collecting track and under one of the guide rails 8 and 9. The fallen and below the guide rail 8 released bottles can be added by the input conveyor 3 to the end of the upper conveyor run or they can

roll in sideways from the conveyor so that they / a right-angled Container 22 are received. The container 2 2 extends along the side and end of the input conveyor 3, such as Fig. 1 can be seen. The fallen and below the. Guide rail 9 released bottles get on the relatively narrow delivery conveyor 4, move transversely to this and fall into the container 23. This container extends along the side edge of the delivery conveyor 4 in the region of the guide rail 9 and preferably directed further downstream, as can be seen from FIG. 1. The in the manner described The release of the fallen bottles from the collecting track prevents these bottles from becoming wedged; Consequently a functional and uninterrupted output process can be achieved, which is a significant advantage with regard to the level of performance.

When moving the article 2 from the relatively long input conveyor 3 on the faster delivery conveyor 4, some instability is imparted to the moving articles and in particular those articles or objects which move close to the guide rail 8 and which are already due to the rollers 12 a certain vibratory motion was given. To overcome this instability or to neutralize it is the collecting conveyor 1 is assigned a stabilizer 24, which acts on each individual article assigned to the individual transport. The stabilizer 24 consists of a flat leaf spring or a spring plate, which is preferably made of high density polyethylene and attached to the downstream end of the guide rail 8. The spring plate extends from there directed essentially downward movement. The stabilizer 24 is at a distance above the discharge conveyor 4, which exceeds at least the diameter of the article 2; as a result, the spring plate remains out of contact with fallen over articles which are transported by the delivery conveyor 4. Stretches in its normal position The downstream or free end of the stabilizer 24 is somewhat the same as the upstream trajectory on the discharge conveyor 4 located article 2, as in Fig. 5 by dashed lines

themselves

Lines is shown. The spring plate can bend / out of the way, when it comes into contact with an article 2 as shown by solid lines in FIG. The stability the article 2 on the moving discharge conveyor 4 is caused by the opposite contact between the

309843/0580

Stabilizer 24 and the opposite guide rail 9 or their downstream extension is improved. A The stop 25 carried by the guide rail 8 is located behind the stabilizer 24 and controls or limits the deflection the spring plate to ensure that the article 2 is on its individual path downstream through the rail extensions 26 and 27 are precisely aligned.

Some overturned articles making their way on the delivery conveyor 4 take, do not fall into the adjacent container in the area of the side guide rail 9 but put their Movement on the conveyor along the stabilizer 24 and in the path associated with the individual transport, which between the downward movement located rail extensions 26 and 27 is formed. According to Fig. 1, the rail extensions extend 26 and 27 essentially parallel along the path assigned to the individual transport and in a curve shape with this, so that fallen, Articles remaining on the track are removed by the delivery conveyor 4. The articles are sent to the next working machine in a single sequence (not shown) delivered after they are freed from the fallen items.

Referring to Fig. 4, the rail extension 26 may comprise a pair of vertically disposed rods, the lowermost edge of which is relatively close to the article-carrying surface 7 of the delivery conveyor 4 is arranged. The slide extension 26 can be an overturned bottle touch according to the dashed line in Fig. 4 along a line which is on the horizontal diameter of the bottle.

-12- 309843/0580

finds. The rail extension 27 on the opposite The side of the web serving for the individual transport is located at a distance above the surface 7 carrying the articles, which at least the diameter of the article, so the bottle 2 exceeds.

The loop formed by the rail extensions 26 and 27 The track includes a first section extending from the downstream ends of the guide rails 8 and 9 to reference line A extends. In this section, the rail extensions 26 and 27 extend diagonally with respect to the the article carrying surface 7 of the discharge conveyor 4 around the article contact surface of the rail extension 26 at the reference line A a distance in from the opposite side edge of the delivery conveyor 4 facing away from the direction, which is smaller than the radius of the bottles 2 corresponds. Between the reference lines A and B, the rail extensions 26 and 27 extend substantially parallel to the side edge of the delivery conveyor 4. Articles which have fallen over and which remain on the delivery conveyor 4 and which pass the reference line A fall usually between lines A and B due to gravitational force down from the conveyor, as the rail extension 26 exerts a certain pressure, which ensures that more in this section than half of each overturned bottle protrudes over the opposite side edge of the conveyor 4. The container 23 is located is close to the discharge conveyor 4 and extends in the direction of the reference line B around the fallen ones from the conveyor

309843/0580

to collect articles dispensed between lines A and B. Even though in the section between the reference lines A and B partially offset from the surface 7 carrying the articles, the set upright standing bottles 2 their movement in the durchfdie rail extensions 26 and 27 formed single track.

In the last section of the path formed by the rail extensions 26 and 27 downstream of the reference lily B are the Extensions, in turn, are curved in order to move the upright bottles 2, which exist in a single row, into one position to guide, which is in the middle of the article-carrying surface 7 of the delivery conveyor 4. In this position put the bottles or articles their settlement in the direction of the next working machine (not shown) continued.

All the elements forming the collecting track including the lateral guide rails 8 and 9, their upstream located rail extensions 10 and 11 and their downstream rail extensions 26 and 27 are adjustable in the vertical direction with respect to the article-bearing surfaces 6 and 7 of the conveyors 3 and 4. The elements are furthermore laterally adjustable in relation to their opposite body, so that the collecting conveyor 1 follows one another Articles of different sizes can be adapted, so bottles 2 of different diameters.

309843/0580

Through the automatic removal of fallen or tipped articles jamming of the collecting track is avoided, which so far has often resulted in a reduction in speed or in a Production was interrupted. The collecting conveyor 1 according to of the invention can be incorporated into production lines, for example a bottle filling machine to load. The collective conveyor is in this use

en
able to maintain the orderly / uninterrupted flow of bottles and has led to an increase in the profitability of the associated work route in the range of about 101.
