Definitions

the invention relates to a device for transferring coins under a stamping and / or cutting press, in particular for parts from a strip material, to ensure the transfer multiple rooms simultaneously from one area feed on a first die of a press table, arranged under one or more stamping tools and / or cutting associated with a press slide, subjected to a alternative movement up and down, and / or from a such matrix from the press table to another for a new machining operation and / or to an evacuation zone, device comprising at least one transfer arm for the taking charge of said documents during transfer, this or these arms being cycled in a vertical plane driven by control means.
the present invention will find its application more particularly in the area of stamping presses.
first transfer means for bring the pre-cut strip section (s) from a cutting device in a waiting position, at the entrance a stamping press. Then, second transfer means are able to take, one by one, said sections of strip in waiting position to route them under the machining stations cited above.
Both the first means of transfer and the second are constituted by two arms extending, as the case may be, below the cutting device or under the waiting strip sections on the table placed upstream of the press. These arms have in their upper songs housing for taking charge of these parts and, through a cyclic movement, the file, with regard to the arms of the first means of transfer, to the waiting table and, for the arms of the latter transfer means, under the stamping press.
the transfer device that constitutes two arms with cyclic movement allows these parts from strip material, systematically one step during a cycle.
control means for actuating these arms of a transfer device they are constituted by a system of the cam-motor type.
the operation of the latter is managed by the stamping press, so that the rise followed by the one step of the different strip sections and the lowering of the arms takes place during the rising phases and lowering of the stamping press.
the present invention aims to further improve the design of these presses, in particular through a perfect synchronism between the rise and fall operations lowering of the press ram in relation to the transfer of parts under the different machining stations.
the invention relates to a device for transferring parts under a stamping and / or cutting press, in particular of parts from strip material, for transfer several parts simultaneously from a feeding zone on a first matrix of a table press, placed under one or more stamping tools and / or cutting associated with a press slide subjected to an alternative movement of ascent and descent, and / or from one such matrix from the press table to another in sight a new machining operation and / or to a zone evacuation device comprising at least one transfer to take charge of said parts during transfer, this or these arms being animated in a cyclic movement in a vertical plane under the impulse of control means, characterized in that said control means are formed, substantially, by the press ram to which the transfer arm or arms are made integral through connecting means with relative mobility, while a cycle guide with which said co-operate simultaneously press slide and this or these arms, is defined suitable for convert the up and down movement of said press slide in one movement according to the predefined cycle of said one or more arms.
Figures 1 to 4 each illustrate schematically a stamping and / or cutting press with which is associated a transfer device according to the invention, this in each of the positions during a stamping cycle.
Figure 5 illustrates, schematically, the cycle of movement of the transfer device arm (s) in the frame of the embodiment corresponding to FIGS. 1 to 4.
Figures 6 to 10 correspond to representations similar to the figures, respectively, 1 to 5 for a mode of different realization leading to a displacement cycle of rectangular type of the transfer arm (s).
this invention relates to the field of cutting presses and / or stamp and relates, more particularly, to a device for transfer 1 under such a press 2, of parts in particular from of strip material.
a press stamping 2 comprises a frame 3 on which is mounted a press table 4 on which are arranged, all particularly, one or, more often, several matrices stamping 5 on which come to be arranged, successively, the parts to undergo, different operations stamping and / or cutting.
Such a transfer device 1 comprises at least one arm for transfer 10. More particularly concerning parts to be taken care of, this device will include, preferably, two identical transfer arms 10 able to extend on either side of the matrices 5 on the press table 4, for taking from a die and / or arrange in one of these, these elongated pieces in grabbing them from their ends.
these transfer arms 10 include in their song upper 11 of the housing 12 likely to accommodate said coins during their transfers, from the area 8 to the evacuation zone 9. Space 13 preserved between two successive housings 12 corresponds, substantially, at the step P to which these parts are subjected during a movement cycle of this or these transfer arms 10.
This cyclic movement of the transfer arms 10 occurs under the impulse of control means 14 which, within the framework of the configuration according to the invention are defined, substantially, by the press slide 7 to which are joined directly or indirectly these arms 10 by connection means with relative mobility 15, 16, 17. While that a cycle guide 18 is provided to guide, during each of the stages of the stamping cycle, the displacements of these transfer arms 10.
the means of connection to relative mobility 15, 16, 17, connecting the press slide 7 the arms 10 are configured to allow movement of these arms 10 by report to said press slide 7 in a direction to horizontal components, taking into account that the stroke horizontal 19 allowed must be at least P that should be communicated to the pieces during their transfer under the press, between said feed zone 8 and the evacuation zone 9.
the intermediate stages of transfer II and of return to initial position IV can cause displacements of this or these transfer arms 10 which are not strictly rectilinear.
the cycle guide 18 comprises, in a plane vertical parallel to the plane of movement of the transfer arms 10, a light 20 taking up, exactly and to scale, the movement cycle communicated to these transfer arms 10.
this light 20 has two portions vertical 21, 22 corresponding to the vertical displacements of these transfer arms 10 during steps I and III and spaced apart by a distance corresponding to a step P.
the respectively lower upper ends of these vertical portions 21, 22 meet through portions of inclined light 23, 24 corresponding, respectively, to stages II and IV of the cycle.
This light 20, in a vertical plane, is crossed by a horizontal axis 25 perpendicular to the plane of movement of transfer arm 10, this axis 25 being, moreover, rendered integral with an extension 26 of this or these latter.
the move command is generated, as shown previously, by the press ram 7.
this press slide 7 extends, vertically, a bracket support 27 on which the axis 25 is also engaged. However so as to authorize component movements horizontal of this axis 25, it crosses, at the level of this support bracket, a horizontal oblong opening 28 adjusted to the section of this axis 25.
the length of this horizontal oblong opening 28 is at least equal to one pitch P.
axis 25 progresses along the inclined portion 23 of light 20 of cycle guide 18 under the influence of press slide assembly 7. As it is a displacement at horizontal component, the axis 25 slides, moreover, along of the horizontal opening 28 of the support bracket 27.
the axis 25 moves vertically, simultaneously with the lowering movement of the slide press 7. After that and continuing its downward movement, the press slide 7 generates the displacement of the axis 25 the along the inclined portion 24 of the lumen 20 which leads, again, to a displacement of the transfer arms 10 according to a stroke equal to the pitch P, so as to be positioned under the parts to be removed during the next transfer cycle.
the vertical portion 21 joined by axis 25 in order to restart the parts transfer cycle has a lower extension 29 which extends below the level of the inclined portion 23 of this light 20 and which corresponds noticeably at the drawing stroke proper.
This extension 29 allows, in any case, to position strictly in vertical alignment axis 25 with respect to this portion vertical light 21 for the next step.
axis 25 constitutes substantially a means of connection to relative mobility 15 connecting the transfer arms 10 to the press slide 7, this through the bracket 27, other axes 30, 31 can thus connect, so complementary, these transfer arms 10 to a bracket 27.
this may include extensions 32 extending parallel to these transfer arms 10.
the vertical displacements of the press slide 7 are systematically accompanied by a component trip at least vertical transfer arms 10, in the mode of embodiment corresponding to FIGS. 5 to 10, these movements of up and down of this press slide 7 generate displacements which either are strictly vertical or strictly horizontal transfer arms 10.
the cycle guide 18A has a light 20A strictly identical to the movement cycle to be transmitted to transfer arm. So, this light breaks down into two vertical portions 21A, 22A and two horizontal portions 23A, 24A.
the axis 25A made integral with the transfer arms 10 and intended to move along this light 20A, it cooperates, moreover, with the support bracket 27A of the slide of press 7 through an oblong oblong opening 28A of width adjusted to the section of the axis 25A and provided suitable for authorize a horizontal displacement of the latter according to a stroke at least equal to the length of the horizontal portions 23A, 24A, i.e. at least equal to the step P.
transfer arms 10 in order to collect coins from the area feed 8 or dies 5, transfer arms 10 must execute the first step I corresponding to the passage of the state of the press shown in Figure 9 to that of the figure 6.
the press slide 7 must execute a first vertical race during which he trains the axis 25A along the vertical portion 21A of the light 20A. It follows, therefore, a strictly vertical displacement transfer arms 10.
the axis 25A immobilized vertically through the light 20A, is caused to progress, however, along the oblong opening inclined 28A in the stem 27. This leads to a displacement horizontal of axis 25A along the horizontal portion 23A of this light 20A and, therefore, to a strictly displacement horizontal of the transfer arm (s) 10 for carrying out the second stage II.
steps III and IV i.e. that axis 25A comes, first of all, to progress along the vertical portion 22A before coming to move along the horizontal portion 24A under the action of the oblong opening of inclined shape 28A on this axis 25A.
the relative mobility link means 15 that here constitutes the axis 25A, on the one hand, integral with the arms of transfer 10 and, on the other hand, cooperating with the gallows 27A of the press slide 7 through the inclined opening oblong 28A, can be repeated in several places along of these transfer arms 10 and an extension 32 of this bracket 37 on either side of the latter.
axes 30A, 31A corresponding to these auxiliary relative mobility connecting means 16, 17, can, as already indicated above, be made united indifferently, transfer arms 10 or extension 32 of the gallows 27 and cooperate through oblong openings inclined 28A1, 28A2 formed at the level of this extension 32 of the bracket 27 or, respectively, of the transfer arms 10.
