Definitions

the present invention relates to a machine for positioning a product in the form of a flexible sheet.
Industrial processing of sheet-shaped products involves providing, between the different processing units, one or more devices making it possible to position the product correctly so that it can automatically switch from one processing unit to another.
This type of device rather rudimentary, is slow to use and requires the presence of one or two operators.
the motors act to cause the tube to twist until the edge of the sheet is brought to the level of the photocells .
This device has the drawback of being complex and therefore expensive to produce, since it requires the use of two drive motors and the production of a specific tube.
the present invention aims to remedy this drawback by providing a device for production and simple use and of moderate cost.
this device is of the known prior type comprising at least one clamp for gripping the sheet and engaging it astride one or more horizontal and parallel rollers, means for causing the opening of the clamp when the two lateral edges of the sheet deposited on the roll (s) are equidistant from the ends of the roll (s), as well as presence detectors of the edge of the sheet aligned horizontally at the desired height for positioning the anterior edge of the sheet, and which control the action of the roller (s) for the correct positioning of this front edge, and in which each roller is associated with a motor intended to drive it in rotation in one direction or the other depending on the signal transmitted by the detectors presence sensitive to the position of the edge of the sheet.
the device comprises means making it possible to tilt the roller (s) relative to the horizontal by tilting about a horizontal axis perpendicular to their axis of rotation and passing through the center of the latter, one presence detectors being arranged in line with the tilt axis, so as to be sensitized by the central point of the anterior edge of the sheet, and to detect the correct positioning in level with this central point to stop the action of each motor for rotating the rollers, while the other detectors, sensitized by the anterior edge of the sheet on either side of its central point, are intended to control the tilting of the roller (s), until detection by them of the correct positioning of this anterior edge.
the motor (s) drive the roller (s) in rotation until bringing the central point from the front edge of the sheet at the level of the detector arranged in line with the pivot axis.
the edge of the sheet acts on the detector which stops the rotation of the roller (s).
the other detectors actuate the tilting means of the latter so that the edge of the sheet is gradually brought into the desired horizontal position. The inclination stops when the edge is at the level of the detectors.
the sheet is then taken over by a processing unit.
this device comprises two parallel rollers around which are engaged several endless belts, perpendicular to their longitudinal axes.
each roller is constituted by two coaxial rollers of identical lengths, connected to each other by a tubular piece or sleeve forming a bearing, which is crossed diametrically by the axis of tilting of the rollers.
the means actuating the inclination of the rollers is constituted by a jack whose body is fixed to the frame of the device, and whose end of the piston rod is connected to one of the ends of the rollers.
the presence detectors of the front edge of the sheet are constituted by photoelectric cells.
this device comprises two clamps carried by a motorized endless belt, which are located opposite one another. This improves the speed of the machine.
this device comprises an inclined ramp facilitating the engagement of the sheet on the rollers.
Figures 1 and 4 show, from different angles, the device 1 which comprises a frame 2 and two parallel and horizontal rollers 3, each constituted by two coaxial rollers 3a and 3b of identical length, connected to each other by a tubular sleeve 4 forming a bearing.
the sleeve 4 is crossed by a horizontal axis 5 perpendicular to the axis of rotation of the rollers 3, and passing through its center.
the ends of the axis 5 are engaged in bores made in two uprights 7, forming a hinge bearing, carried by a spar 2a of the frame 2.
the rollers 3 are connected, by one of their ends, to the rod piston 8a of a jack 8 whose body 8b is fixed to the frame 2.
the frame 2 carries photoelectric cells 10 aligned horizontally, one of which 10a is located in line with the axis 5.
the cell 10a controls, by appropriate means (not shown) the action of motors (not shown) for driving the rollers 3 in rotation, while the photoelectric cells 10 control, by appropriate means, also not shown, the action of the jack 8.
the device 1 also comprises two clamps 11 secured to a motorized endless belt 12, which is guided by rollers 13, the clamps 11 being located opposite one another.
the device 1 is provided with an inclined ramp 14 facilitating the handling of a sheet 15, as well as a pusher 16 movable in translation, provided for transferring the sheet 15 from the device 1 to a processing unit 17 of the sheet 15, which is shown in dashed lines in FIG. 4.
the clamps 11 are intended to grip a part of one of the side edges 15a of the sheet 15, and to engage the latter astride the rollers 3, so that two edges 15b and 15c of the sheet 15 hang on either side of the rollers 3.
the device 1 comprises a photoelectric cell, fixed on the side of the ramp 14, and a sensor connected to a computer (not shown), which measure the length of the sheet 15 in order to cause the opening of the clamp 11 having gripped the sheet 15, and therefore the deposition of the sheet 15 on the rollers 3, when the two lateral edges 15a of the sheet 15 are at equal distance roller ends 3.
the motors After depositing the sheet 15, the motors will drive the rollers 3 in rotation to gradually bring the central point of the ante edge laughing 15b of the sheet 15 at the level of the photocell 10a.
the rotation of the rollers 3 is interrupted when the edge 15b is at the level of the cell 10a (FIG. 2), and the cells 10 then actuate the jack 8, which causes the tilting of the rollers 3 relative to the horizontal. around the axis 5 until the edge 15b of the sheet 15 coincides with the alignment of the cells 10 (FIG. 3).
This alignment corresponds to the correct horizontal positioning at the edge 15b of the sheet 15.
the pusher 16 and the rollers 3 then act to transfer the sheet 15 to the engagement system of the processing unit 17.
the rollers 3 are brought back in a horizontal position for the engagement on them of another sheet 15.
the presence of two clamps 11 makes it possible to improve the performance of the device 1.
