Definitions
- the present invention relates to the automatic handling of parts, in particular during the course of a production, when the parts which come from a processing station in a given direction and a position must be presented in a second processing station in a direction and a predetermined position different from those they have in the first post.
- the invention relates preferably to the manufacture of textile articles, during which the textile pieces, which are unit parts of the article, pass from one station to another to undergo all the hemming operations. , folding, assembling, sewing ... which will give birth to the fully made article.
- the object of the invention is to provide a method which not only performs the transfer but also the positioning in the sense that it changes the orientation of the part.
- the method according to the invention is characterized by the features of claim 1.
- This method can be implemented in a transfer installation which, according to the invention, is characterized by the features of claim 4.
- the part is fed from the first station by sliding on a flat surface thanks to the displacement of the first means of transport which can be a belt; when the part reaches the first given location, the movable table, the sliding surface of which is in the high position in line with the sliding surface of the first station, lowers, thus releasing the part from contact with the first means of transport.
- the workpiece is supported by the transfer means which transfers it by sliding on the mobile table, from the first to the second given location while giving it the position and orientation determined when it reaches said second location.
- the movable table is raised and the part, freed from the transfer means, is taken up by the second transport means which transfers the part, by sliding on a surface which is in the extension of the sliding surface of the movable table in the high position, at the second position in the predetermined direction and position.
- the means for lowering the movable table when the workpiece reaches the first given location comprises a position sensor element which materializes the first given location and a support element which exerts on the table sufficient pressure for it to pass from the position high to low position.
- the high position corresponds to that where the part is both in contact with the first means of transport of the first station and with the surface of the table; the low position corresponds to that where the part is only in contact with the table surface, and is therefore no longer driven by the first means of transport.
- the position sensor element controls the vertical movement of the support element so that, taking into account the mechanical inertia, the part reaches the first given location when the support element has passed the table. the high position to the low position.
- the transfer means comprises a displacement member, which by moving can rotate on itself around an axis perpendicular to the plane of displacement.
- the movement member is itself the support element which moves the table in height. So when the position sensor element detects the presence of the part, the support and displacement element is applied to the part as soon as it has reached the first given location, the pressure exerted on the part puts the table in position low, which releases the part from the first means of transport, and simultaneously the support and displacement element moves the part on the table to the second given location.
- the support and displacement element from the first to the second given location, it turns on itself around an axis perpendicular to the plane of displacement, so that the part has the predetermined position when it reaches the second location given.
- the means for raising the movable table when the workpiece reaches the second given location comprises a second position sensor element which corresponds to the second given location and a counter-support element which brings the movable table back from the low position, where it holds it. support element, in the high position.
- the second position sensor element controls the raising of the support element, so that, taking into account the mechanical inertia, the part reaches the second given location when, the support element no longer exerting its pressure on the table, it goes up.
- the part is then taken over by the second means of transport, which can be one or more belts having the predetermined direction; in this case the belt drives the part by sliding towards the second station in the predetermined position and direction. It is generally preferable to facilitate the adjustments that the belts ensuring the transfers to the first and to the second station have perpendicular directions.
- the transfer and positioning installation comprises a table 1 movable in height, that is, as shown in FIGS. 1 and 2, that said table can pivot around an axis 2 parallel to the direction of supply of the part, or that table 1 can move entirely vertically.
- the surface of table 1 when the latter is in the high position, is in the same plane with on the one hand the sliding surface corresponding to the first station from which the part originates and on the other hand to that corresponding to the second post to which it is directed. Furthermore, these three surfaces are approximately contiguous, so that a part can pass by sliding from one to the other without the formation of folds or other defects.
- the belt 3, which conveys the part of the first station extends both over the sliding surface of said first station and over a part of the table 1.
- a window 4 made in table 1 and a lamp not shown are placed opposite a photoelectric cell 5.
- the element of support and displacement consists of a comb 8 which comprises two fingers 9 and 10, one of which 9 is mounted fixed on the carriage 6 while the other 10 can pivot around the vertical axis constituted by finger 9.
- the comb 8 moves up and down thanks to the opening of the trigger 11, opening controlled by the photoelectric cell 5 when it detects the presence of the part on the table 1 at the right of the window 4.
- the comb 8 moves laterally thanks to the movement of the carriage 6 itself.
- the finger 10 pivots by a certain angle around the finger 9: this pivoting is obtained by the combined action of the compression spring 12 which tends to repel the finger 9, and of the roller 13 which limits this pivoting, the roller 13 being integral with the comb 8 and bearing on a ramp 14.
- the angle of this ramp 14 relative to the predetermined direction 6 is adjustable by means of the screw 15, the ramp 14 being biased against this screw by a spring not shown.
- a stop 16 triggers the raising of the comb 8 by pressing on the lever 17, integral with the comb 8.
- the complete movement cycle of the comb 8 therefore comprises 4 continuous phases: descent, lateral movement for example of left to right in Figure 1, ascent, moving from right to left.
- a guide assembly a part of which consists of a wheel 18 is integral with the lever 17 and therefore of the carriage 6 and the other part of which, consisting of two bars 19 and 20, is fixed relative to to the carriage 6.
- the bar 19 parallel to the bar 20 is mounted above the latter. One of its ends is located opposite the trigger 11, while the other end overhangs the corresponding end of the bar 20.
- the operation of the transfer and positioning installation is as follows.
- the part 23 is conveyed by means of the belt 3 by sliding on the horizontal sliding surface of the first station and then partially on the table 1 (FIG. 2A).
- the interruption of the illumination of the lamp located below this window is detected by the photoelectric cell 5, which controls the opening of the trigger 11.
- the wheel 18 which was held between the trigger 11 and the bar 19 is released, and authorizes the descent of the comb 8 until the caster 18 meets the bar 20.
- the comb 8 in lowering rests on the part 23 at the 'using fingers 9 and 10, and exerts pressure on the table 1 which pivots around the axis 2 ( Figure 2B).
- the comb 8 drives the part 23 which slides on the inclined surface of the table 1 (FIG. 2C).
- the inclination of the table 1 is identical to that of the bars 19 and 20 relative to the horizontal, since it is the movement of the caster 18 along the rod 20 which guides the movement of the comb 8.
- the roller 13 secured to the comb 8 follows the direction of the ramp 14 against which it is pressed under the effect of the compression spring 12: thus during this lateral displacement, the finger 10, which follows the movement of the roller 13, pivots around the vertical axis formed by the finger 9. This relative movement of the two fingers 9 and 10 relative to one another makes it possible to give the part 23 the desired position.
- the angle by which the part will pivot around the fixed finger 9, during lateral movement from left to right can be adjusted by modifying the angle formed by the ramp 14 relative to in the direction of transfer of the carriage, by action on the adjusting screw 15.
- the stop 16 bears on the lever 17 secured to the carriage 6. By tilting, the lever 17 raises both the caster 18 and the comb 8.
- the comb 8 no longer exerts pressure on the table 1, and the latter returns to the high position under the effect of the counterweight 24: the part 23 comes into contact with the belts 21 and 22 which have the determined direction, and is driven by them in the position and the direction determined by sliding first on a part of the table 1 then on the sliding surface of the second station (FIG. 2D).
- the connecting rod-crank continues to drive the carriage 6: the caster 18, raised under the action of the lever 17, is passed over the rod 19 and guides in its movement from right to left the comb 8 towards the position initial.
- a new part 23 is supplied from the first station, and the cycle resumes.
- the part 23 is a sleeve from of a first finishing station having effected for example the hemming or the colleting of the bottom of the sleeve (25), then the folding (26) of the sleeve along an axis of symmetry 27 and so that there has exact overlap of the two parts of the sleeve one over the other.
- the part 23 must be closed; this closure is effected by sewing the two edges 28, adjusted and superimposed.
- the installation according to the invention includes all the adjustments necessary for changes of parts and position, in particular adjustment of the ramp (14) by the screw (15) but also adjustment of the finger (s) (9 and 10) depending of the size of the parts, adjustment of the opto-electronic sensor control delay as a function of the choice of the first location, adjustment of the stop (16) and of the stroke of the crank-rod (7) as a function of the length of the displacement lateral desired.
