Definitions
- Device and method for the preparation of mandrels device for collecting the coiled mandrels and device and method for handling the mandrels
- the present invention relates generally to the winding of mandrels.
- the invention more particularly relates to a device and a method for preparing mandrels intended to be slipped on a bar, spaced apart from each other.
- the invention also relates to a device for collecting wound cores and a device and method for handling said mandrels.
- Known chucks are known from the state of the art in the form of a table provided with a groove in which the operator introduces and aligns the mandrels one after the other according to their desired position on the table. bar. The bar is then threaded by the operator along the axis of the aligned mandrels.
- Such a preparation table makes it possible to thread several mandrels on the same bar and then, by introducing the bar into a winding machine, to perform a simultaneous winding of the mandrels.
- the mandrels are introduced one by one into the table, which slows down the operation of preparing the mandrels.
- the positioning of the mandrels is not accurate and the operator is likely to make mistakes.
- US-A-2,493,590 and US-A-5,941,474 disclose devices for preparing a set of mandrels, wherein the latter are stored in compartmentalized tanks placed opposite the desired locations of the mandrels on the bar. . These devices do not allow a great flexibility in the size of the mandrels, because it is necessary to change the walls of the compartments when changing the length of the mandrels.
- robots designed to automatically enter a mandrel, position it in a winding machine and extract it from said machine once wound. Such a robot can automate the winding operation of said mandrel. However, the robot can only handle one chuck or one reel at a time. In addition, unless considerably increase the cost of design of the robot, such robots do not allow the successive manipulation of mandrels of different lengths.
- the purpose of the present invention is to enable rapid and precise positioning of several mandrels on the same bar according to the desired relative positions of the mandrels.
- Another object of the present invention is to make it possible to easily and quickly produce coils whose mandrels are of different lengths.
- Another object of the present invention is to limit the risk of misalignment of the mandrels on the bar.
- the invention relates to a device for preparing a set of mandrels intended to be slipped on a bar, spaced apart from each other, characterized in that said device comprising at least two grooves disposed close to one of the other, namely:
- a feed groove for receiving mandrels 1 aligned along the axis of said groove and juxtaposed by their end face, said groove being associated with juxtaposition means of said aligned mandrels, the means of juxtaposition of the mandrels arranged in the feed groove comprising a device for conveying the mandrels along the feed groove, associated with a stop at one end of the groove to axially immobilize the mandrels aligned in said groove in a juxtaposed position,
- a mandrel receiving groove selected from the mandrels aligned with the feed groove, said receiving groove being equipped with abutment members positionable in said receiving groove along the axis of said groove to delimit individual receiving housings of the selected mandrels, the device also comprising means for transferring the selected mandrels from the feed groove to said individual receiving dwellings.
- Such a preparation device makes it possible to position a plurality of mandrels on the bar. After threading on a bar, it is thus possible to proceed to the simultaneous winding of these mandrels.
- the preparation device according to the invention thus makes it possible to increase the production rate of coils.
- such a device is suitable for the preparation of mandrels of different sizes, simply by changing the positioning of the stop members in the receiving groove.
- the mandrels can be easily and quickly positioned in the receiving groove by being spaced from each other according to their desired position on the bar. Indeed, the use of a mandrel feed groove allows to benefit from a reserve of mandrels near the receiving groove. The selected mandrels can then be quickly transferred into the receiving groove housings for threading the mandrels onto the bar.
- the means for juxtaposing the mandrels make it possible to obtain a continuous line of mandrels juxtaposed by their end face and thus aligned along their axis. Thanks to such a juxtaposition of mandrels in the feed groove, the position of each of the mandrels can be easily determined. It is thus possible to select the mandrels of the feed groove positioned opposite the individual housings of the receiving groove, which allows easy and fast transfer of said mandrels into said housings.
- the combined use of a mandrel feed groove near the receiving groove and mandrel transfer means provides the possibility of simultaneously transferring the selected mandrels from the feed groove to the receiving groove in the housings formed by the stop members, which provides a high production rate.
- the lengths of mandrels threaded onto the bar are preferably identical.
- the lengths of mandrels on the bar are different from one mandrel to another. It can also be expected that from one cycle to another preparation the mandrel lengths are different.
- the position of the stop members along the receiving groove is adjusted to delimit individual housings in accordance with the desired relative position of the mandrels with each other. Since the positions of the mandrels along the feed groove are known, the transfer means can easily transfer the selected mandrels to said receiving housings.
- the bar can then be threaded by one end of the receiving groove into the hollow axis of the aligned mandrels, spaced apart from each other, in a direction of threading which corresponds to the direction of movement of the selected mandrels in abutment against the stop.
- the selected mandrels can thus be immobilized all on the same side, which allows a reliable and accurate threading of the bar in the mandrels by maintaining the desired relative positions of the mandrels with each other and with respect to the bar.
- the combination of a stop and the conveying device keeps the mandrels juxtaposed and aligned in the feed groove. Indeed, the mandrels retained by the stop are pushed against each other by the conveying device.
- the position of the end stop and the length of the mandrels being known, the position of each of the mandrels arranged along the feed groove is known precisely.
- the receiving groove is equipped with a device for axial displacement of the received mandrels to bring them into the receiving groove in abutment against the corresponding abutment members positioned in said groove.
- the axial displacement device makes it possible, once the selected mandrels have been transferred into the individual housings of the receiving groove, to bring said selected mandrels into axial abutment against said abutment members.
- the cores brought into abutment are thus precisely and stably positioned in the receiving groove according to their desired relative position for threading onto the bar.
- the axial displacement device thus makes it possible to make up the clearance that exists between the mandrels and the stop members after the transfer of said mandrels into the housings.
- said means for transferring the selected mandrels comprise radial thrust members intended to be applied, by a thrust end, against the peripheral wall of the selected mandrels, said thrust members being movable between a starting position in which said members are set back from the feed groove and a final position in which the thrust end of said members is arranged in line with the receiving groove, the position of each thrust member being preferably axially adjustable in relation to the selected mandrels to be transferred.
- the feed groove and the receiving groove being arranged close to one another, the use of thrust members makes it possible to easily transfer said selected chucks from the feed groove to the corresponding recesses of the throat. reception.
- the positioning aid means comprise at least one element extending parallel to the axis of the receiving groove and provided with teeth, in the manner of a rack, adapted to cooperate with corresponding teeth provided on the distal end of each of the stop members positioned along the axis of the receiving groove.
- Each tooth of an element of the positioning aid means constitutes a positioning step of the abutment member along the axis of the receiving groove.
- the positioning of the stop members in steps makes it possible to obtain precise, stable and reproducible placement of the abutment members.
- two positioning aid elements are provided, the teeth of the first element being offset relative to the teeth of the second element.
- a tooth width for example of two millimeters, makes it possible to choose the positioning of the abutment members in steps of one millimeter, with an initial positioning error of less than two millimeters. It is thus possible to place the organs of stop to use a robot whose accuracy error can reach up to a little less than two millimeters while obtaining a placement of the stop member in steps of one millimeter. It is thus possible to use a robot of lower cost.
- each axial abutment member positioned along the axis of the receiving groove extends substantially perpendicularly to the feed groove to form a radial abutment of the unselected mandrels, so as to retain said unselected mandrels in the feed groove.
- the stop members thus combine several functions, which makes it possible to limit the size of the preparation device and to reduce the costs thereof.
- the device comprises at least one covering element of the mandrels housed in the receiving groove, such as a plate, said or each covering element being movable between a position in which it covers at least partially said groove to maintain said mandrels within the receiving groove and a position in which said groove is uncovered.
- the cover member thus forms an active cover when threading the bar into the mandrels to form an upper retainer so as to prevent the mandrels from escaping their housing.
- the covering means are formed by a single covering element extending over the entire length of the receiving groove.
- the covering means may be provided by a plurality of cover members which, for example, extend each along a portion of the receiving groove to cover the individual housings of mandrels.
- the device comprises means for verifying the positioning of each mandrel along the bar, the verification means preferably comprising an image capture device, such as a camera, and an image processing software.
- the invention also relates to a handling device which comprises, on the one hand, a device for preparing empty mandrels as described above, with a view to threading them on a bar, and, on the other hand, a device for collecting filled mandrels, called coils, carried by the bar with a view to their stripping, said device comprising a groove, preferably in V, for receiving the coils in individual bobbin housings delimited by axial abutment members, the position of each abutment member being adjustable along said coil receiving groove to define said individual coil housing, of axial length substantially equal to that of individual housings of mandrels of the receiving groove of said preparation device.
- the receiving groove of the coils thus comprises in a manner similar to the receiving groove of the mandrels, abutment members which are positioned to form housings adapted to receive the packed mandrels or coils, and retain said mandrels packed in their housing.
- the coils maintain a precise position in abutment against said stop members of the coils.
- the V-groove allows to receive coils of different diameters, which makes the device adaptable to different winding lengths on the mandrels, leading to varying thicknesses.
- the positioning aid means comprise at least one element extending parallel to the axis of the receiving groove of the coils and provided with teeth, in the manner of a rack, capable of cooperating with corresponding teeth arranged on each of the stop members positioned along the axis of the receiving groove of the coils.
- the invention also relates to a method for preparing mandrels for threading them on a bar, spaced apart from each other, which comprises the steps of: a) positioning, along a receiving groove of the mandrels, of stop for delimiting individual housings for receiving mandrels intended to be threaded, each stop member being positioned as a function of the desired position of said mandrels on the bar, b) brought, by means of a conveying device, of a series mandrels aligned and juxtaposed by their end face in a feed groove disposed near the receiving groove of the mandrels, the order of steps a) and b) being any, c) transfer, preferably simultaneous, mandrels for threading, from the feed groove to the receiving groove, in said individual housings of mandrels, d) axial displacement of the mandrels transferred to the housings ind each of the receiving groove to bring them into abutment against the stop members.

- Such a geometrical configuration of the two elongated elements 21, 21 'and their teeth 22, 22' makes it possible to position a coil stop member 11 with a precise pitch (in this case a millimeter) corresponding to half of the spacing between two teeth. of the same element.
- the two superposed longitudinal elements 21, 21 ' are slidably mounted on rails 23 for displacement transverse to the axis of the groove 8 for receiving the coils so as to catch the clearance between the teeth 22, 22' of the elements 21 and 21 'and the teeth of the stop members 11.
- Such transverse displacement can be achieved with a jack system 17 as illustrated in FIG. 7.
- each abutment member 11 comprises a central portion 11A, one side of which serves as an axial stop vis-à-vis an adjacent coil 16.
- the central portion 11A has a notch allowing the passage of the bar as well for its removal in the groove 8 with the coils for its extraction of the coils.
- This central portion 11A is extended on one side by an end portion 11 B which bears on a longitudinal edge of the groove 8.
- the other side of the central portion 11A is extended by another portion 11 C in inverted U shape, which bears on the other lateral edge of the groove, and ends with end teeth 11 D adapted to cooperate with the teeth 22 or 22 'of the elements 21, 21' of the positioning aid means 20.
- Parts 11A, 11B, 11C and 11D are advantageously aligned.
- the collection device further comprises holding means 15 in position of the stop members 11 of the coils in the groove 8 for receiving the coils.
- These holding means 15 are here formed by a clamping plate making it possible to hold the end portion 11 B of each abutment member 11 against a longitudinal edge of the groove 8.
- the method of handling the mandrels using the handling device described above comprises the following main steps: a) positioning, along the receiving groove 3 of the mandrels 1 ', 6 abutment members to delimit the housing individual receiving 18 mandrels 1 'intended to be threaded, each stop member 6 being positioned according to the desired position of said mandrels on the bar 7, b) brought a series of mandrels 1 aligned and juxtaposed in the groove 2 feeding device disposed near the receiving groove 3, the order of steps a) and b) can be any, c) transfer, preferably simultaneous, mandrins 1 'selected to be threaded from the throat 2 d feeding up the throat
- step a) or b) the number of abutment members 6 to be positioned in the receiving groove 3 is determined and their axial position is determined along said groove 3, at least as a function of the length and or the number of mandrels 1 to be mounted on the bar 7.
- the stop members are positioned in the receiving groove 3 so as to define the individual housings 18 of the mandrels according to the desired positions of the mandrels on the bar.
- the position along the groove 3 of the flank of the portion 6A of a member 6 forming an axial stop corresponds to the desired position of the end face of a mandrel on the bar.
- each stop member 6 it is possible to double each stop member 6 by another member 6 'abutment.
- only one of the organs of stop acts as an axial stop vis-à-vis a selected mandrel.
- the use of a pair of abutment members 6 serves to form two radial abutments vis-à-vis an unselected mandrel 1 intended to remain in the feed groove 2 during the transfer of the selected mandrels, in order to keep it in the feed throat 2.
- the precise positioning of the abutment members 6, 6 ' is obtained thanks to the positioning aid means 14 as described above.
- the operator or the robot selects the member 6 or 6' corresponding abutment and brings it into engagement with the teeth of the element 12 or 12 'associated.
- the abutment members 6, 6 ' are put in place by the top of the receiving groove 3 to engage with the teeth 13, 13' of the elements 12, 12 '. Once the stop members positioned along the groove 3, the elements 12, 12 'are moved radially to catch the residual clearance between the teeth 13, 13' of the elements 12, 12 'and those of the members 6, 6' of stop. The abutment members 6, 6 'are then immobilized axially in their desired position in the groove.
- the bare mandrels are conveyed and contiguous one behind the other along their axis in the feed groove 2 by a conveying device (not shown).
- the conveying device continues to be activated while the mandrels 1 are held by the abutment 4.
- the mandrels arranged in the feed groove 2 are pushed against each other, which makes it possible to obtain a line of mandrels aligned and juxtaposed by their end faces.
- the position of the abutment 4 and the length of each of the mandrels being known, the position of each mandrel along the feed groove 2 is also known.
- This conveying device associated with the feed groove 2 (not shown) comprises, for example, similarly to the conveying device 10 associated with the receiving groove 3 (visible in FIG. 1), two parallel endless loops formed by belts on which the mandrels rest 1. The belts run in and along the corresponding groove to move the mandrels 1 along it.
- the members 9A, 9B for pushing the transfer means 5 are positioned facing the mandrels 1 'selected to be transferred into the individual housings 18.
- the mandrels 1' selected correspond to the mandrels of the feed groove 2 whose corresponding positions correspond to substantially at the desired relative positions of the mandrels with each other on the bar 7.
- the so-called selected chucks are those arranged opposite the individual housings 18.
- the cover 26 is initially in the covered position to allow the transfer of the mandrels 1 in the individual housing 18 formed between adjacent pairs of members 6 and 6 '.
- the selected mandrels are pushed by the thrust members 9A, 9B into the housings 18 of the receiving groove 3.
- the thrust members 9A, 9B are simultaneously moved radially relative to the axis of the groove 2, until coming to the right of the receiving groove 3, so that the pushed chucks take place in the individual dwellings 18 correspondents.
- one chuck out of two is moved in the groove 3 of receipt.
- the feed groove 2 is raised relative to the receiving groove 3 so as to allow easy transfer of the mandrels to the housing 18.
- the push 9A, 9B extend transversely above the feed groove 2 and their end is interposed between the portions 6B and 6E of two adjacent pairs of members 6, 6 '. Due to the radial abutment portions 6B and 6E, the unselected mandrels are not driven and remain in the feed groove 2.
- the thrust members 9A, 9B are withdrawn, which allows to release the feed groove 2 and to regroup all the unselected chucks 1 up to the stop 4 to form a new alignment of juxtaposed mandrels and complete alignment with other mandrels, so as to prepare a new threading cycle of mandrels on a bar.
- the mandrels transferred to the housings 18 are then moved by a movement along the arrow F, by the conveying device 10 abuts against the side of the corresponding stop members 6 to reach their desired precise position.
- the lid 26 then covers the mandrels 1 'to hold them in place.
- the bar 7 is then threaded by one of its ends in the hollow axis of the mandrels positioned in the receiving groove 3.
- each stop member Due to the shape of the central portion 6A of each stop member allowing the passage of the bar 7, the bar is easily threaded along the axis of the mandrels 1 ', these maintaining their relative positions through the axial abutments of said abutment members 6. Once the bar 7 threaded into the mandrels, the lid 26 is raised to release the receiving groove and allow removal from above the bar with bare mandrels.
- the upwardly open shape of the central portion 6A of each stop member facilitates the extraction of the bar from above.
- each bar is provided at its ends 7A, 7B of geometric shapes that allow its entry to handle it. Handling of the bar can be carried out manually or by a robot equipped with shape-grasping means complementary to the ends of the bar.
- the mandrels 1 are held in position on said bar 7 by means of holding means, such as a system formed by rubber studs capable of being displaced radially to the bar by injection of compressed air inside the bar which is hollow in this example.
- holding means such as a system formed by rubber studs capable of being displaced radially to the bar by injection of compressed air inside the bar which is hollow in this example.
- the nipples bear against the inner peripheral wall of the mandrels, and thus ensure the positioning of said mandrels on the bar.
- the bar 7 provided with the empty mandrels 1 'held in their desired position first passes in front of an image capture device (not shown), such as a camera, associated with an image processing software for verifying that the positions of the mandrels along said bar correspond to the desired positions and is introduced into the winding machine (not shown).
- the mandrels are then filled, that is to say wound, simultaneously, by winding a ribbon, here a thermal transfer ribbon. Once the winding is completed the robot or the operator removes the bar of said winding machine.
- the mandrels are, as illustrated in Figure 6, coated with a thermal transfer ribbon coil. Each packed mandrel forms a coil 16.
- the bar provided with the coils 16 is then placed in the collection device (FIG. 7) either by the operator or by the automatic positioning device controlled by the electronic and computer processing unit.
- the abutment members 11 Prior to the laying of the bar 7 in the collection device, the abutment members 11 have been positioned in the receiving groove 8 to form individual housing 19 for receiving the coils, of length substantially equal to the length of the housing 18 of the corresponding mandrels.
- said abutment members 11 are associated with positioning aid means 20, similar to the other positioning aid means, formed of two superposed longitudinal elements 21, 21 'provided with teeth 22, 22'. which cooperate with teeth of the abutment members 11.
- the means for holding the coils on the bar are then deactivated, for example by releasing the compressed air from inside the bar, which allows the pins to retract inside said bar so as to allow the mandrels to slide. on the bar.
- the bar 7 is then extracted by pulling along its axis while the coils are held in their housing between the abutment members 11, abutting them.
- An automatic gripping device or not can then individually enter the reels in their slots for storage in bins.
- the new positions of the stop members and the thrust members are adjusted, if necessary, according to the length of the mandrels and their desired position on the bar.
