(54) APPARATUS FOR GUIDING OBJECTS AND A METHOD
OF OPERATING THE APPARATUS
(71) We, STORK BEPAK B.V., a Netherlands limited liability Company, of 2, Groeneweg, Utrecht, the Netherlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The invention relates to apparatus for guiding objects (e.g. bottles) and is particularly concerned with apparatus of a type which divides an incoming row of objects into two or more outgoing rows. Apparatus of this types serves, for instance, for dividing a row of bottles supplied from a filling machine before onward conveyance to a packing machine or to two or more labelling machines.In the foodstuff industry such apparatus is often used inter alia for a packing machine, a rinsing machine, or a continuous sterilizer.
Up to now, known apparatus operated according to the Drängel principle which, especially in the case of cylindrical containers, causes little or no difficulties. The containers supplied in a single row are divided into two or more rows on conveyors, sometimes with the use of moving guides between these tracks.
One drawback of this system is noise resulting from collisions at high velocity of containers supplied, against containers stowed up. Considerable noise also results as the supply row is divided into two or more rows of objects. Another drawback is frequent breakage of contaners or the damage to labels. Another most important drawback of the known Drängel principle is that it is only applicable to cylindrical containers. In the case of square, rectangular or oval sections, this system cannot be used. Experience shows that obstructions will arise.
A system of dividing a single row of noncircular section containers into two or more rows is known. This, however, is intermittent since the containers supplied have to be stopped periodically for making a switch, after which a batch of containers is carried off in the desired direction. The inost important drawbacks of this system are the limited capacity and the noise.
It is an object of the invention to provide a apparatus by means of which a single row of objects may be divided into two or more rows in a simple manner without interruptions and without the containers having to contact each other.
The invention provides apparatus for guiding objects, comprising means for conveying incorning objects along a first path.
means for conveying outgoing objects along a combination of the first path or along at least a second path guide means above the conveying means and operable to allow objects to pass thereby from the first path to the continuation thereof or to divert objects from the first to the second path, said guide means comprising two guide parts extending at an angle to the first and second paths and movable in a common plane jointly or individually, and means, disposed adjacent said guide means, for monitoring the passage of objects.
The invention also provides a method of operating the apparatus set forth in the preceding paragraph, comprising:
a) starting with the first guide part in a position on the side of the first path remote from the second path and with the second guide part in a position on the side of the first path adjacent the second path and intermediate the first and second guide parts so that objects can pass from the first path to the continuation thereof through an opening between the two guide parts
b) moving the first guide part towards the second guide part at a velocity equal or substantially equal to the velocity at which the conveying means moves the objects along said first path until the opening between the first and second guide parts is closed or substantially closed, to divert objects from the first to the second paths.
c) subsequently jointly moving the first and second guide parts until the first guide part occupies its initial position, and
d) then after a desired number of objects has becn diverted from the first path towards the second path moving the second guide part to its initial position at a velocity equal or substantially equal to the velocity at which the conveying means moves the objects along said first path.
It is thus possible to introduce the guide means into and withdraw it from a row of moving objects in the same direction as that in which the objects are carried off, as a result of which only a very gradual sideward movement of the objects will occur.
During movement of the guide parts, the objects bearing against and coming into contact with relevant guide parts will show practically no difference in velocity with respect to the guide part. As a result thereof, it is possible to define both the beginning and the end of the diverting movement very accurately and no violent movement of objects will result. The invention is, therefore, particularly suitable for handling unstable or breakable objects.
Because movement of the objects does not need to be slowed down or arrested periodically, considerable throughput may be achieved. The average velocity of the objects will be equal to the maximum velocity, and this is not the case in the known systems.
Return movement of the second guide part to its initial position is in the same direction as that in which the first guide part is moved from its initial position towards the second guide part, the result being that movement of objects along the continuation of the first path is immediately reinstated without any obstruction occurring, unlike the prior art systems.
The invention will now be more particularly described, by way of example, with reference to the accompanying drawings, wherein:
Figures 1 to 4 are plan views showing one emhodiment of apparatus for guiding objects according to the invention, in consecutive stages of operation,
Figure 5 is a plan view of another embodiment of the apparatus,
Figure 6 illustrates a device for slowing down the velocity of movement of diverted batches of objects, and
Figure 7 is a cross section on an enlarged scale along the line VIZ VIZ in Figure 1.
Referring to Figure 1, the apparatus shown therein comprises a conveyor 1 on which objects 2 are moved in a single row.
Adjacent to the conveyor 1 there is a second conveyor 3 which runs parallel to and adjoins the conveyor 1. For diverting a number of objects 2 from the conveyor 1 to the conveyor 3, there is provided a guide 4 which makes an angle n with the direction of movement P of the objects 2. The guide 4 comprises first and second guide parts 5, 6 which are arranged in a common plane. The parts 5 and 6 are movable in their longitudinal direction both jointly and individually in said common plane. The second guide part 6 is located within a U-shaped frame 7 (see
Figure 7) which extends on only one side of the supply conveyor I and which forms a guide for the objects 2 on the stage between the supply line I and the conveyor 3. A similar frame 7 is provided for the first guide part 5 (see Figure 2) but this frame has nq functiori in the shifting of the objects 2.
The guide parts 5 and 6 are movable by motive members 8 comprising, for example, a pneumatic cylinder arranged in the frame 7. Figure 7 illustrates such a cylinder in cross section.
Figures I to 4 show different stages of operation of the guide 4. Initially both guide parts 5 and 6 are in retracted positions (see
Figure 1) spaced apart from each other to provide an opening therebetween and through which the objects 2 pass along the conveyor 1. So as to divert the objects towards the conveyor 3, the guide part 5 is extended at a velocity equal or substantially equal to the velocity of movement of the objects 2 on the conveyor I until the opening between the guide parts 5 and 6 is closed or substantially closed (see Figure 2). The objects 2 will then be diverted by the guide parts 5 and 6 to the conveyor 3. The guide part 5 is then retracted as the slide part 6 is simultaneously extended (see Figure 3).The opening remains closed or substantially closed and the objects continue to be diverted to the conveyor 3 but this time by the guide part 6 and the frame 7 associated therewith.
Now when the desired number of objects 2 have been diverted from the conveyor 1 to the conveyor 3, the second guide part 6 is retracted at a velocity equal to said velocity of movement of the objects 2 on the conveyor 1 (see Figure 4). The objects 2 upstream of the guide 4 on the conveyor 1 will then pass along the conveyor 1 past the guide 4 and through the opening between the guide parts 5 and 6. Thus it is possible, in a simple manner, to obtain the desired number of objects on the conveyor 3 and on the conveyor 1 downstream of the guide assembly 4.
The apparatus also includes monitoring means 9 comprising a selenium cell 10, a light source 11 and a counter 12 with several counting mechanisms (see Figure 1). The monitoring means will provide an impulse to which the motive members 8 of the guide parts 5, 6 will be responsive. By means of a simple programme the desired number of objects may be directed to each of the conveyor 3 and the extension 1' of the conveyor 1. It is to be appreciated that instead of selenium cells, microswitches, proximity switches, pneumatic or accoustic means may we used.
The apparatus shown in Figure 5 differs from the apparatus of the foregoing figures by the provision of two guides 13 and by the provision of three conveyors 3, 3' and 3" which, together with the extension 1' of the conveyor 1, form four discharge conveyors.
Also the elements 10--12 are provided threefold. Due to the fact that a limited number of objects 2 is supplied to the guides 13, these guides may be single-action and there is no need for the application of the two-part construction of the guide 4.
It should be noted that the objects may be supplied to the conveyor 1 free from each other, i.e. arbitrarily arranged or standing against each other, although a little space between the objects promotes correct operation. The velocity of movement of the conveyors 1 and 3 should be equal. The apparatus divides the objects supplied into batches of a limited number of objects. These batches have the same velocity of movement as the supplied row.
The counter 12 comprises several counting mechanisms operable to allow first undiverted batches of objects to continue along the conveyor I and to diven second batches of objects to the conveyor 3, where the number of objects in the first and second batches respectively is not necessarily equal.
Figure 6 shows a device for reducing the velocity of the objects. For this purpose, a number of conveyors 14 adjoin the conveyors 3. The velocity of the conveyors 14 is, for example, 25% of the velocity of the conveyor
I and the objects on the conveyors 14 will then each have 1/4 of the supply velocity of the objects 2.
The apparatus described above is particularly useful for dividing a row of bottles, these being relatively unstable objects. Indeed, plastics bottles of circular or other cross-section may be handled. During the treatment of square or rectangular bottles no change of orientation occurs. The latter is important if it is desired to carry out a check or if uniform orientation of the objects during packing is desired.
