Receipt of the first conveyor element (the structural element is located below the exit of the conveyor device), which is obtained at a position of 1γ and which is successively received by at least one opening during the movement of the first conveyor element in the conveying direction. in each case likewise successively into a receiving device for the carrier elements located at the outlet, and at least one measuring and/or testing device and a first and a device for discharging from at least one conveying opening of a conveyor element.

In particular, the invention provides rod-shaped structural elements, in particular r MELF J
The electrical rod-like structural elements, called ``Electric Rods'' and which are obtained in irregular quantities after manufacture, are conveyed individually in each case at a predetermined position into a recess of the belt or into a receiving device, after which the belt or its receiving device is coated with a suitable material, e.g. The object of the present invention is to provide a device that allows closing with material in the form of a tape.

The problem that the prior art and the invention aims to solve is that of ferromagnetic materials, which have very small dimensions (sizes of less than 2-3 millimeters) and, in contrast to conventional structural elements, are not provided with terminal leads. Rod-shaped electrical structural elements having only contact surfaces are gaining importance in the production of electrical circuits. In order for the circuit to automatically set these structural elements, they are placed in belted form, ie the individual structural elements are in each case placed in a predetermined position on the belt receiving device. It is necessary for the structural elements to be made in such a belted state and in the position or orientation determined by the peltoy (e.g. in the case of polarized structural elements such as diodes). (with respect to the poles) to automatic equipment. In order to almost completely eliminate equipment errors in automatic installations of electrical circuits containing a large number of structural elements, the belting of rod-shaped elements is carried out with the greatest possible accuracy and in particular the belting is performed before defective structural elements are removed. It must also be carried out in such a way that no discontinuities of structural elements, i.e. receivers without structural elements, occur in the belt.

Since rod-shaped structural elements are susceptible to the action of mechanical forces, careful handling of the structural elements is necessary during the separation and introduction of the structural elements into the receiving device of the carrier element.

The invention therefore provides a device for separating and placing rod-like structural elements, in particular electrical rod-like structural elements, on a carrier, preferably a prepared receiving device for the belt, with a simple construction and with the necessary inspection for defect-free belting. The object of the present invention is to provide a structure which allows belting to be carried out with a high degree of accuracy even in the event of discarding or discarding defective structural elements, and in particular, without causing any discontinuation of the structural elements in the belt. .

It is characterized in that a chute is provided following the transfer zone between the first conveyor element and the second conveyor element.

Operation and Effect The device described above operates according to the following basic principles, regardless of any other specific structure. That is, the structural elements obtained in the receiving position of the first conveyor element are each successively received by the conveying opening of the first conveyor element and conveyed to the delivery position of the first conveyor element, where they and is introduced by the second conveyor element preferably directly into the carrier or belt receiving device. All inspection and measurement operations (testing of mechanical accuracy of use and in particular testing of electrical operability) and disposal of defective structural elements are carried out on the first conveyor element, and any active or polarized electrical In the case of structural elements (such as diodes, for example) it is possible to pivot the structural element when the spatial orientation is incompatible with respect to polarity, and there is also a reliable supply of articles and precisely positioned structural elements. 2 shots
Since it is provided in the transition area between two conveyor elements, the breaks in the structural elements on the second conveyor element are filled and therefore no breaks in the structural elements occur on the carrier or belt.

Due to this magnetic structure, the structural elements are respectively placed in the desired position or held in this position in the receiving position. In addition, the magnetic structure is such that when the conveying gate passes through the receiving location, the maximum concentration of magnetic field lines occurs approximately within or slightly below the bottom of the at least one conveying opening of the first conveyor element. It has become. In this way, it is possible for the structural element to be drawn into the conveying opening by the magnetic field lines.

When using the device 54 for removing and resupplying structural elements, the guiding surface 34 is interrupted in the area 34' by a magnetic structure 56, which in a manner described below allows the structural element 3 to move into the recess 1.
3 to prevent it from falling off.

The chute 16 and the intermediate chute 18 are bounded in the direction of movement of the conveyor elements 6 and 7 by plate-like elements 31 and 32 in each case. The conveyor elements 6 and 7, with their rear end surfaces not visible in FIGS. 3, 4, 5 and 10, are directly adjacent to the auxiliary plate 35° fixed by spacers to the front side of the plate 10. The recesses 12 and 13 are bounded on one side by this auxiliary flat plate. Similarly, elements 31 and 3

In order to place the structural element 3 made of ferromagnetic material at the end 3' forming the connection in the required orientation on the chute 16 in the area of the receiving position 17, a magnetic structure 3G is used.
is provided there, and the magnet structure 36 is connected to the auxiliary flat plate 35.
and a permanent magnet fixed to the auxiliary plate 35". The two permanent magnets forming the magnet structure 36 have in each case one pole attached to the conveyor element 6
35" and 35", respectively, and are held therein (e.g. in a recess). One permanent magnet has its south pole facing the associated auxiliary plate. and the other permanent magnet has its north pole placed against the associated auxiliary plate. Elements 31 and 32 and auxiliary plates 35" and 35" are made of (non-magnetic) material that does not influence the magnetic field lines. If made completely, these elements and the auxiliary plate are made of such material, at least in the immediate vicinity of the permanent magnets, which are aligned in a direction perpendicular to the auxiliary plate.

As shown in FIG. 6, the magnetic field lines MG of the magnet structure 36 are directed at right angles to the side surfaces of the auxiliary plates 35'' and 35'' and in the direction of the longitudinal extension of the groove-shaped recess 12, i.e. the structural element 3.

In addition, the arrangement of the permanent magnets of the magnet structure 36 is such that the magnetic core of each pole arranged on the auxiliary plate is closer to the axis of the shaft 8 than to the surrounding surface 6', i.e. the maximum concentration of the magnetic field lines MG passes through the magnet structure 36. It is approximately at a distance of only =25= from the area of the radially inner bottom of the recess 12 or the axis of the shaft 8.

In this way, not only are the structural elements 3 held in the receiving position 17 by the magnetic field lines MG in the required orientation for reception in the recess 12, but also the structural elements 3 are each inserted into the recess 12 in the receiving position 17 by the magnetic structure. 36.

A magnet structure 37 corresponding to the magnet structure 36 is provided in the transfer area or in the receiving position of the conveyor element 7, i.e. in which permanent magnets are attached in each case to the auxiliary plates 35' and 3'.

In addition, the structural element 3 in the chute 18 is fixed in the position required to be received by the recess 13 and in each case drawn into the recess 13.

Following the receiving position in the conveying direction, the conveyor element 6 has a measuring position 38, which in the illustrated embodiment is arranged at the point where the midplane M intersects in each case the negative part of the circumferential surface 6'. It is set up. In the simplest case, this measuring position 38 shown in FIG. It is reciprocated and each time the structural element 3 is in the measuring position 38 during the stop phase of the conveyor element 6 it is advanced briefly and brings its tip through the opening in the auxiliary plate 35' into contact with the contact surface of the structural element. Electrodes 40 are arranged on the auxiliary plate 35''. Electrodes 39 and 40 are connected to a measuring and evaluation device (not shown in detail), so that the structural element 3 is connected during the stop phase of the conveyor element 6 (
preferably during the second stop phase) in the measuring path between the electrodes 39 and 40 and said electrodes 39 and 40 are connected to the structural element 3.
Each time the measuring and evaluation device abuts the end 3' of the structure, the measuring and evaluation device checks the position and orientation of the respective structural element with respect to its polarity and the operability of the structural element. In order to prevent the structural element 3 from being transported together with the returning electrode 39, an auxiliary magnet 40', whose magnetic field holds the structural element, is provided on the electrode 40 made of non-magnetic material.

A discharge position 41, which is shown in detail in FIG. 8, is provided on the comparator 1 element 6 following the measuring position 38 in the conveying direction.

This discharge position follows the measuring position 38 in the conveying direction by at least one rotational step (preferably at least two rotational steps or a multiple thereof) of the conveyor element 6 on the auxiliary plate 35.
The recess 12 essentially has an air outlet nozzle 42 fixed at an angle such that the recess 12 moves its end past the outlet 1-1 of the nozzle/12 and facing said flat plate. The opening cross section of the nozzle 42 is substantially smaller than the diameter of the structural element 3, and the nozzle 42 is connected via a compressed air opening 43 to a normally closed valve connected to a source of compressed air. It is provided on the auxiliary flat plate 35" opposite to the nozzle 42 in the direction perpendicular to the side surface of the 1-1 flat plate 35",
The opening 44 opens into one end of the tubular member 45, the other open end of which is located above the open side of the container 46 for receiving the defective structural element 3. Measurement position 3
During the inspection of the structural element 3 at 8, when said structural element is found to have a defect, the measuring and evaluation device cooperating with the electrodes 39 and 4 generates a signal, which signal is transmitted to the conveyor element 6. actuating a valve to supply compressed air to the nozzle 42 when the structural element 3 reaches the discharge position 41 after further movement of the conveyor element 6 and when said conveyor element 6 is in the stop phase;
The structural element is thereby blown out of the recess 12 and passes through the opening 44 and the tube element 45 into the container 46 . In order to prevent the structural element 3 from entering the opening 44 when not desired, a permanent magnet 42'' in the form of an annular magnet is provided in the nozzle 42.

A stationary pivot position 47, which is shown in detail in FIG. 9, is provided in the area of the conveyor element 6 following the discharge position 42 in the conveying direction. This pivoting position 47 essentially has a tubular member 49 which is bent in the shape of a semicircle and which has an internal diameter larger than the diameter of the structural element 3 and smaller than the length of said structural element. This allows a structural element in the tubular element 49 to be displaced in the longitudinal direction, but this structural element cannot turn in the tubular element 49 about an axis extending at right angles to its longitudinal extension. One end of the tube member 49 is connected to the auxiliary flat plate 35
The other end of the tube member 49 is connected to the opening 51 of the auxiliary flat plate 35'', and the openings 50 and 5

7 has an opening 51 which continues to the opening 50 in the transport direction and is arranged below the opening 50 in the vertical direction. An air outlet nozzle 52 is provided in the auxiliary plate 35'' opposite the opening 50 in a direction perpendicular to the side surface of the auxiliary plate 35'', the air outlet nozzle 52 being an outlet of a normally closed valve connected to a source of compressed air. is connected to the compressed air duct via a compressed air duct.

activation, but if it occurs that the structural element 3 in the measuring position 38 is not in the desired position with respect to its polarity, i.e. the anode of the structural element 3, formed for example as a diode, is connected to the contact 39 as desired. Instead of touching
When the cathode abuts contact 39, contacts 39 and 40
A measuring and evaluation device connected to generates a signal which is transmitted to the compressed air line 53 when the structural element 3 in question reaches a position between the air outlet nozzle 52 and the opening 50 during the stop phase of the conveyor element 6. Activate the connected valve. By means of the air jetting out of the nozzle 52, the structural element 3 is blown out of the recess 12 previously receiving it and blown through the opening 50 into the tube element 49, so that after one rotation step of the conveyor element 6. The structural element is the auxiliary flat plate 35
It can be reintroduced into the empty recess 12 from the side remote from . By moving along the tube member 49, the structural element is rotated by 180°, thereby placing it in the correct position with respect to its polarity on the conveyor element 6. The same recess 12 that was blown out by MiJ in order to rotate the structural element 3 in this way
used to receive again. To make this possible, the periphery of the conveyor element 6 is provided with an auxiliary opening 12', which is constructed in the form of a through hole and in each case in an elongated direction parallel to the axis of the shaft 8. It is formed with a line of extension and is at the same radial distance from said axis as the recess 12. Each auxiliary opening 12' opening on both end faces of the conveyor element 6 has a diameter smaller than the diameter of the structural element 3 and smaller than the cross section of the recess 12.

Each auxiliary opening 12' is arranged between two recesses 12 such that the distance from the adjacent recess 12 corresponds to one revolution step of the conveyor element 6. Structural element to be pivoted 3
After being blown out through the opening 50 during the stop phase of the conveyor element 6, the structural element 3 which has reached the auxiliary opening 12 after a turn [151] in the tube member 49 is still in this stop phase. ” on the end face of the conveyor element 6.

The conveyor element 6G is then moved by one revolution step, so that the auxiliary quantity I 12 ' is in the area of the opening +-150 and the empty recess 12 is in the area of the opening 51. The structural element 3 is then blown through the opening 51 into the empty quadrant 12 by the air stream' further ejected from the nozzle 52 and passing through the auxiliary opening 12'. Only then is the air flow emerging from the nozzle 52 interrupted.

The auxiliary opening 12' prevents air from becoming trapped inside the tube while the structural element 3 is being blown into said tube.

It should be understood that an opening 51' having a very small cross section compared to the diameter of the structural element 3 is provided in the auxiliary plate 35' opposite the opening 51. To prevent unswiveled structural elements from slipping undesirably into the opening 50, an annular magnet 5 corresponding to the annular magnet 42' is used.
2' is provided in the nozzle 52. Another permanent magnet 5
1" is arranged in the auxiliary plate 35" opposite the opening 51. The pivoted structural element 3 is further drawn through the opening 51 into the recess 12 by the permanent magnet 51".

Due to the described steps, only structural elements 3 that can be activated and have a specified position and orientation with respect to their polarity reach the transfer position 11.

The structural element 3 with this orientation is then advanced in the manner described above onto the conveyor element 7 and finally inserted into the receiving device 2 of the belt I. The fact that the auxiliary chute 18 of the transfer zone 11 can receive a predetermined number of structural elements 3 and thus acts as an intermediate storage or buffer means that the individual defective structural elements 3 are discharged from the conveyor element 6 in the discharge position. when the conveyor element is missing a structural element after passing through the discharge location 41, the transfer area 11
It is ensured that all recesses 13 of the conveyor element 7 are always provided with a structural element fully activated and in the correct position with respect to its polarity, so that after the structural element 3 has been transferred to the belt 1 No empty receiving devices 2 or structural elements are missing from the belt 1. In order to ensure that there is always a reliable supply of structural elements 3 in the auxiliary chute 18, at least one conveyor element 6 or 7 in each case
The conveyance or rotational speed of the conveyor element 7 is controlled, so that, for example, when the conveyor element 6 is constantly circulating, the conveyance speed of the conveyor element 7 is reduced to increase the number of structural elements 3 in the auxiliary chute 18, or on the other hand preferably the conveyor The element 7 is adapted to be stopped whenever the supply of structural elements 3 in the auxiliary chute 18 falls below a minimum value and to be started again when there is a sufficient supply of the structural elements 3 in the auxiliary chute 18. .

For control purposes, the auxiliary chute 18 is provided with at least one optical path formed by a light source 48 and a photodetector 48°, such that the optical path of the light source 48 and photodetector 48° is blocked by the structural element 3. The conveyor element 7 is then stopped. It is likewise possible to control the rotational speed of the conveyor element 6 by means of a constant conveying action of the conveyor element 7. The number of actuations of the compressed air valve of the discharge location 41 in a given time unit is suitable as a control criterion.

A device 54 for removing and refeeding structural elements is provided on the conveyor element 7 following the transfer zone 11. This device is essentially used for making belts of a certain length without a structural element 3 at the beginning of the operation. However, this device is also used to fill possible structural element gaps in the conveyor element 7 with structural elements 3. In the area of the device 54, the guiding surface 34 is interrupted at 34'', so that the element 32 is formed in two parts and the two parts are spaced apart from each other, so that a space 35 is formed between the auxiliary plate 35' and the auxiliary plate 35'. 35''. The outer surface of the auxiliary plates remote from the conveyor element 7 has in each case one plate-shaped arm 56 fixed to them.
Each of the plate arms has a permanent magnet 3 at one end.
5 is supported. Two permanent magnets 57 are part of the magnet structure 36
The magnetic field lines MG are arranged with different polarities so as to correspond to the permanent magnets 57, that is, the magnetic field lines MG between the two permanent magnets 57 are aligned with the axis 9.
It extends parallel to the axis of 1j. The two arms 56 are each rotatably and rigidly fixed to a shaft 58 which is pivotally mounted on the auxiliary plates 35'' and 35''.
