Short designation: Device for the transport of small parts with flat lips on their edges · 5 The applicant mentions the inventors as André DECSULLE and

Marcel BEGIN.

The invention relates to a device for transporting small parts which are provided with flat lips on their edges.

To move such parts from one station to another during manufacturing, they can be placed on a conveyor belt. These belts are often relatively bulky and do not allow transportation along a non-linear path.

The object of the invention is to provide a device of the aforementioned type which is not very bulky and which follows a non-rectilinear path, whereby the parts can nevertheless be transported separately, while the device is accurate and adjustable. Characteristic of the device according to the invention comprising these two belts, means for bringing the facing sides of these belts together until the flat lips of the parts to be moved are clamped between them, and means for spacing these facing sides again until they release the flat lips,

According to a first variant, in which the bands are trapezoidal or rectangular, the sides facing each other between which the flat lips are held are the side surfaces or the small sides thereof. According to a second variant, with bands which are also trapezoidal or rectangular, the sides facing each other between which the flat lips are clamped the sides of the major bases or the major sides thereof,

The invention will be elucidated hereinafter with reference to the accompanying drawing of two exemplary embodiments of 790 7 445 - 2 devices for displacing printed wiring, respectively, according to the above first and second variant.

Pig, 1 schematically shows a transport device in which the trapezoidal belts clamp the connecting lips of the printed chains between their sides;

Pig «2 shows in view the diabolo which keeps the sides of the trapezoidal bands in contact with each other;

Fig. 3 schematically shows a perspective view of a transport device in which the trapezoidal belts clamp the connecting lips of the printed wires between their large bases;

Fig. 4 shows in elevation the parts which contact the large bases of the trapezoidal belts,

In the device according to Figs. 1 and 2 there is seen a plate with printed wiring IA, provided with connecting lips 2, while that 15 is just clamped by means of those lips between the sides of the trapezoidal belts 3 and 4, whereby the supply device plate has been passed between the belts a short distance in front of the diabolo 10. The trapezoidal belts are guided by the disks 5 and 7 with pivot shafts 6 and 8 respectively, one of which is driving. These are provided with an intermediate plate such as 9, through which the bands 3 and 4 are kept at a distance of about 1 mm. The diabolo 10 presses the bands 3 and 4 together and against each other by means of its surfaces 14 and 15, so that the belts come into contact with each other under pressure along a vertical plane 16 (see fig. 2). The contact is maintained along the entire path of the belts between the diabolos 10 and 11. Beyond the diabolo 11, the belts separate from each other again by running in the direction of the disk 7, and then the printed chains such as 1B fall on a receiving means such as a small conveyor belt 13 or a cistern. 30 In the device according to fig. 3 and 4, the printed wires such as 21A, are provided with lips 22, clamped by means of these lips between the trapezoidal belts 23 and 24 »which are guided through the discs 25 »26 with vertical shafts 27» 28, after these bands have passed between the clamping discs 33 and 34, and up to 35 the location of the discs 35 »36, after which the bands are separated 790 7 4 45 * Γ - 3 - 3 - Remove in order to focus respectively on the guide discs 29 »30 with vertical shafts 31» 32. One of the sets of discs 25 »26 or 29» 30 provides the drive.

The printed chains placed between the hands slightly in front of the disks 33 »34 are carried between those hands up to the disks 35» 36, and as soon as the hands are some distance apart they fall on a small conveyor belt 38 or a cistern .

Owner. 4 shows clearly how the clamping disks 33 »34 contact the hands 10 23» 24 together according to the large bases in a vertical plane 39 *

The invention is particularly applicable to the transportation of printed-wire parts from one fabrication station to another »but more generally to the transportation of all small parts having flat lips at their edges» such as connecting pins .
