Description

Device for inspecting objects from different angles
The invention is in the field of inspecting objects transported by a conveyor. It is known for this purpose to make use of a video camera placed next to the conveyor to form an image of each passing object, a second video camera placed downstream of said video camera, which in principle performs the same function, but each object under can observe a different angle by the presence of means for rotating each object through a selected angle between the two video cameras. For example, it is known to transport bottles, jars or other rotationally symmetrical objects in an upright position and to have them with their peripheral surface on the one hand engaged by an endless side conveyor and on the other hand against a fixed rough wall, whereby the containers are rotated about their vertical axis of symmetry. a desired angle determined solely by the circumference of the objects and the effective length of the rotary device described.
Such a device has the drawback that it does not lend itself to non-rotationally symmetrical objects and, moreover, it cannot be adjusted in connection with objects of a different shape. It is therefore necessary, when switching to other types of objects, to take mechanically free radical measures in order for the device to rotate the objects through a desired angle. Even small changes are hardly or not possible for an optimal setting.
The invention provides an apparatus for successively inspecting supplied identical objects, which apparatus comprises: - a supply conveyor for successively supplying the objects, - a first inspection station placed next to said supply conveyor for inspecting the passing objects from one side and delivering them. of an inspection signal associated with the inspection result, to which inspection station any lighting means may be added, - a discharge conveyor for discharging the objects, - a second inspection station placed next to said discharge conveyor for inspecting the passing objects from one side and issuing a inspection signal related to the inspection result to which second inspection station any lighting means may have been added, - an intermediate conveyor placed between the supply conveyor and the discharge conveyor, and - to the intermediate conveyor additional rotation means for rotating each object through a selected angle about a selected axis of rotation, for example the vertical-symmetry axis of symmetrical objects, such that the first inspection station observes each object at a first angular position and the second inspection station observes each object at a second angular position, - said rotation means comprising at least one pair of two endless conveyors, each object engaging together on either side of its axis of rotation, which conveyors are driven at different speeds by individual drive means, which speeds are selected in relation to - the circumferential shape of the objects at the level at which the endless conveyors engage, - the chosen angle of rotation, - the effective common length of the endless conveyors, and - the chosen transport speed corresponding to the average speed of the two endless conveyors. ID of the objects in the area of the intermediate conveyor.
This device according to the invention offers great flexibility. The drive means, in particular motors, for each of the conveyors can be stepper motors or servo-controlled motors, so that a very high accuracy with regard to the rotation achieved can be obtained by means of a simple programmable unit. In practice, a maximum inaccuracy of plus or minus 0.2% with simple electronic means and stepper motors is no problem.
In order to be able to inspect objects from different angles, for instance in total over the entire circumference, the device can be characterized by an arrangement of successive similar devices for observing the objects at different angular positions.
In particular, the device may be characterized in that the angular positions are chosen such that an object is completely observed by the cooperating inspection stations.
For inspecting transparent objects, the device can have the feature that each inspection station is adapted to observe the wall placed between the rotation axes and the inspection station, and the wall placed on the other side relative to the rotation axis. With a rotation of 90 ° between two consecutive inspection stations, it is possible to obtain a complete image of the objects.
A particular embodiment is characterized by at least two pairs of two endless conveyors each, at least four conveyors each being driven by individual drive means at speeds selected in connection with the circumferential shape of the objects at the level at which the pairs of endless conveyors engage.
The two pairs of these endless conveyors will generally engage the objects at different heights. The accuracy of the desired speeds, which can easily be achieved according to the invention, then ensures that all objects with their axis of rotation are always moved parallel to themselves, so that no other movements are made except the translation and the desired rotation.
Particularly for articles that are not completely round, it may be advantageous if the pairs of endless conveyors are resiliently compressible for adaptation to non-circular peripheral shapes of articles. Even hexagonal, pentagonal, square and even triangular objects can be treated without problem by the device according to the invention.
The device is preferably characterized by an optionally programmable control unit for controlling the speed with which the drive means drive the endless conveyors.
In order to keep the difference between the supply conveyor and the intermediate conveyor within certain limits, for example on the order of a few percent at the most, a speed transmitter is preferably used which supplies a signal representative of the speed of the supply conveyor to the control unit, which also on this basis determines the drive speed of the endless conveyors.
Rotation by means of an intermediate conveyor comprising two pairs of endless conveyors engaging at different heights has the advantage of effectively preventing oscillations of the objects. In particular in the case of, for example, soil inspection in the area of the intermediate conveyor, this can be of great importance in connection with the precise timing of flash exposure or the like. In the case where small oscillations can be tolerated, it is sufficient, for example, for hanging transport, in which tapered, more or less elastic transport members engage in pairs under the top edge of the neck of bottles.
The device according to the invention offers considerably increased flexibility. Particularly in the case where programmable controllers are used for the various drives, an almost unlimited flexibility and adaptability to different object shapes can be obtained.
It will be clear that by suitable adjustment of the speed in the region of the intermediate conveyor relative to the speed of the feed conveyor, a spacing or spacing can be achieved. Spacing is achieved by a higher speed of the intermediate conveyor than the speed of the feed conveyor; reverse spacing.
Attention is drawn to the fact that the effective speed of the axis of rotation of the objects at the intermediate conveyor is equal to the average speed of the two endless conveyors of each pair.
If desired, the speed control can take place in such a way that the supplied objects do not press against each other in the area of the intermediate conveyor, but are nevertheless conveyed without any significant spacing. This is referred to as pressureless throughput.
It will be clear that an output signal from the video cameras can be used to assess the passing containers and whether or not to emit them on the basis thereof.
It is noted that the control of the various drives could for instance take place by means of an on-line measurement of the relevant dimensions of the containers to be treated.
The invention will now be elucidated with reference to the annexed drawing. In it show:
Fig. 1 a bottle carried by transport fingers;
Fig. 2 is a view corresponding with FIG. 1 of a bottle, which is transported by conveying fingers and, moreover, by laterally pressing endless conveyors;
Fig. 3 is a schematic top view of a device according to the invention with the conveyors according to FIG. 2;
Fig. 4 two cascaded devices according to the invention with three video cameras; and
Fig. 5 is a partly broken away perspective view of the mechanical construction of the device according to FIG. 3.
Fig. 1 shows a bottle 1 with a neck 2, at the free end of which a collar 3 extends circumferentially. The bottle 1 is carried by rubber-elastic conveyor fingers 4, 5, to be shown in more detail below with reference to Fig. 5, which form part of a pair of respective endless conveyors. The transport fingers 4, 5 are driven longitudinally at different speeds V 1, V 2, whereby the bottle 1 rotates about its axis 6, as indicated by arrow 7.
Due to this speed difference - V2, the bottle 1 is subjected to a given rotation about the axis 6 over a given effective length of the endless conveyors, of which the conveyor fingers 4, 5 form part.
The disadvantage of the suspended transport according to Fig. 1 could be that the bottle 1 undergoes slight oscillations, which may be the case in particular when the bottle is subjected to an acceleration or deceleration when it is passed through the transport fingers 4 , 5 is recorded.
Fig. 2 shows the same view as FIG. 1, however, the bottle 1 is additionally supported laterally with light clamping by further transport fingers 8, 9, which form part of a second pair of endless conveyors, and prevent oscillations in all directions of the bottle 1.
The transport fingers 8, 9 are driven at speeds V3 and V4, respectively. In order to fulfill the obvious condition that the center line 6 must move parallel to itself during transport of the bottle 1, the speeds of the transport fingers 4, 5, 8, 9 must satisfy the relationship:
Vi: v2 = v3: V4
Fig. 3 is a plan view of an inspection device 10 for successively inspecting the bottles 1. The device comprises a supply conveyor belt 11, which is driven by a motor 12, a discharge conveyor belt 13, which is driven by a motor 14, and an intermediate conveyor 15, which is placed between the supply conveyor belt 11 and the discharge conveyor belt 13 and the bottles 1 and 1 thereof. decreases and delivers.
A video camera 16 with associated video monitor 17 is placed next to the supply conveyor belt 11. An optical system of four mirrors 18 is added to the camera 16, which can form two images on the video camera 16 from different angles on one video image. For example, the two angles of view can be approximately 90 ° apart. With transparent bottles 1 this allows both the front and the rear side of a bottle to be inspected in one pass.
A second video camera 19 with associated monitor 20 is placed next to the discharge conveyor belt 13. A system of four mirrors 21 is also added to this camera 19, identical to the system of mirrors 18.
By the rotation described below, which the intermediate conveyor undergoes the bottles 1, the video camera 19 detects each bottle 1 at an angle 90 ° different from the angle at which the video camera 16 detects the same bottle. Thus, with the arrangement of the mirrors resp. 18 and 21, the two cameras 16, 19 together fully inspect a clear bottle in one pass.
The bottles 1 are carried by the intermediate conveyor on their collars 3 by a pair of top endless conveyors 21, 22, which respectively. the fingers 4 and 5 of FIG. 2, and a pair of bottom endless conveyors 23, 24, respectively. wear fingers 8, 9. The conveyors 21, 22, 23, 24 are driven via rollers generally designated 25 by respective motors 26, 27, 28, 29, which are controlled from drives, respectively. 30, 31, 32, 33. These receive control signals from associated programmable dividers 34, 35, 36, 37, which in turn receive control signals from a microprocessor 38 and a signal corresponding to the speed of the feed conveyor 11. This speed signal is generated by a tachometer (not shown) coupled to the drive motor 12, which delivers pulse series 39, the pulse frequency of which is representative of the revolution speed of the motor 12 and thereby transforms the linear speed of the feed conveyor 11. A pulse frequency voltage converter 40 the signal 39 in a voltage signal, which in turn is converted by a voltage-frequency converter 41 into a frequency signal which is supplied as a control signal to the dividers 34, 35, 36, 37, does not need the speed of the intermediate conveyor 15 to be exactly the same to be that of the supply conveyor belt 11. Sufficient if the respective speeds do not deviate too much from each other, for instance maximally in the order of a few percent.
The given circuit with the converters 41 and 42 makes it possible nevertheless to obtain precise control even at extremely small speeds of the supply conveyor belt 11. Depending on the speed of the conveyor belt 11, the output signal of the converter 41 can vary, for example, between 0 and about 1 MHz.
The motors, 26, 27, 28, 29 can be stepper motors, so that very high transport accuracy can be realized with very simple means. If desired, motors with servo control can also be used.
The microprocessor 38 is pre-charged with the effective length of the intermediate conveyor 15. As will be apparent, if the effective lengths of the pairs 21, 22 and 23, 24 are different, it is sufficient to determine the effective length of the longer of the two pairs in the microprocessor 38 as fixed data. Furthermore, the desired angle of rotation of the bottles must be pre-recorded in the microprocessor 38. In the described exemplary embodiment, this rotation angle is 90 °.
Furthermore, the microprocessor 38 must receive information regarding the circumferential shape of the bottles 2 at the level at which the pairs of endless conveyors 21, 22 and 20 respectively. 23, 24 engage.
In this case of rotationally symmetrical bottles, it is sufficient to measure the diameter of the bottles at the level of engagement of the fingers 4, 5 and 8, 9 according to FIG.
2 and input as data into the microprocessor 38.
Fig. 3 shows displacement sensors, respectively. 42 for the lateral position of the endless conveyors 21, 22, and 43, 44 for the endless conveyors 23, 24.
Fig. 4 shows a configuration in which triangular bottles 45 are subjected to two successive rotations of 120 ° each. Use is made of three video cameras 16, 19, 46, which video camera 46 is placed next to a discharge conveyor 47, which connects to a second intermediate conveyor 15 ', which in turn connects to the discharge conveyor 13. After the explanation with reference to fig. 3, further details of the device of Figure 4 are omitted. It is noted that an angle mark 48 on the bottles 45 makes it clear how in this embodiment the full inspection takes place on all three upright side surfaces of each bottle 45.
Fig. 5 shows the mechanical structure of, in particular, the intermediate conveyor 15 of the device 10 according to FIG. 1 in more detail.
The intermediate conveyor 15 comprises a gag frame 49 with four screw spindles 51 rotatable by a handle 50, with which carriages 52 cooperate, which are movable up and down together by operating the handle 50. The carriages 52, in turn, support and guide screw spindles 53 with two opposing threads, with which carriages generally designated 54 cooperate. By rotating the screw spindles 53 by the common drive motor 55, the carriages 54 can be moved apart and towards each other. The carriages 54 carry the rollers 25 and the motors 26, 27. The construction described permits vertical joint movement of the upper conveyors 21, 22, as well as an opposite horizontal movement.
The lower conveyors 23, 24 are movable in the same manner. The adjustable construction for the top conveyors 21, 22 is described in detail. The adjustability of the lower conveyors 23, 24 will therefore be omitted with reference to Fig. 5. It is noted that the vertical position of the lower conveyors 23, 24 is fixed.
Attention is drawn to the fact that near the rollers 25 there are rollers 56, both at the input end and at the output end of the intermediate conveyor 15. As the figure clearly shows, this makes a "searching" and very reliable introduction of the bottles 1 into the intermediate conveyor 15 insured.
