Definitions
- the present invention relates to a movable box feeder feeder, more specifically intended to equip the sheet feed magazine with a processing, in particular shaping, machine. corrugated boxes.
- suction feeders are very widely used in the industry of corrugated cardboard boxes, and are described in numerous patents, such. as for example the French patents 1,343,103 and 1,568,091.
- All these devices use one or more suction boxes, movable in the longitudinal direction, and the upper part of which is closed by a horizontal plate provided with holes, which transmits the vacuum to the sheet and thus allows, for at least one part of the cycle. extraction, to grip the cardboard.
- the present invention relates to a suction feeder of high efficiency and simple, reliable and inexpensive production. It is characterized in that at least part of the suction plate of its suction box or at least one of its suction boxes is associated with a frame, or the like, of flexible material, which surrounds it so forming with it a hollow suction cup whose flexible edges are located above the upper level of said plate or portion of plate in the absence of a vacuumed sheet, that is to say when said edges are raised, and are on the other hand in alignment with or below said upper level of said plate or portion of plate when a sheet is vacuumed, that is to say when said edges are folded down.
- each suction plate equipping the box or boxes is surrounded by a thin frame of flexible material forming an acute angle with the plane of said plate towards the outside thereof, this suction plate being positioned at a higher level, and slightly slightly higher, than that of the table on which it is fixed.
- the material constituting this thin frame is composed of a coating of plastic material, or the like, bonded to a fabric, such as a woven nylon fabric, the side in. canvas being positioned upwards, that is to say on the side of. the cardboard sheet to vacuum.
- this frame can be cut from a sheet of certain materials intended for. the making of belts.
- the feeder shown is a feeder very similar to that described in French patent 1,343,103 (or U.S. 3,226,108) cited above. It includes in particular a magazine 1, containing the stack 2 of sheets of corrugated cardboard to be extracted one by one from the underside of said stack, and delimited at the rear by a stop 3 adjustable according to the format of the sheets, and at l 'before by the margin knife 4 defining with the margin table 5 a space e sufficient to let pass a sheet of cardboard and only one.
- the box 6 is connected to a vacuum source, not shown, by means of a pipe 8 and a distribution solenoid valve 9.
- the solenoid valve 9 is controlled so as to that the vacuum is applied to the box 6 during its sampling and advancement phase of the bottom sheet of the stack, and is released during the backward phase of said box.
- the vacuum is applied to the bottom sheet through a horizontal plate 10 provided with holes 11 and the surface of which advantageously has the shape of sawtooth undulations clearly visible in FIG. 1.
- the edges of the suction plate 10 are cut so as to have a shape complementary to that of the edges 13 of the perimeter plate 12.
- the plate 10 is intended to be screwed onto the body of the box 6 using the screws 16 by fitting tightly into the bottomless bowl 13. Between the two is placed a continuous seal 17 flat and m i n-ce made of flexible material, extending beyond the edges of the bowl 13 and in extension therewith, as can be seen in the drawings, so as to form, with the suction plate 10, a suction cup with edges 26 raised upwards and forming an acute angle ⁇ with the horizontal.
- the seal 17 is formed from a flat frame 18, shown in Figure 3, provided with a central opening at the four corners of which are cut slots at 45 degrees 20 .
- Many flexible materials ranging from the metallic sheet to the elastomer, can be used for the construction of the seal 17.
- the Applicant has found that excellent results are obtained by using the sheet with belts, constituted in a conventional manner. of a woven nylon fabric on which a sheet of plastic material is glued, and mounting the seal 17 of so that the fabric is located upwards, that is to say looking towards the stack 2, or towards the inside of the suction cup (10-17) of the invention.
- the thickness of the suction plate 10 and that of the flexible frame 17 are determined relative to the periphery 12 so that the upper face 21 of the plate 10 is located above the upper face 14 of the periphery 12, with a difference in height at least equal to the thickness of the frame 17. In this way, the flexible frame 17 will never have to support the. weight of. battery 2.
- the operation of the device of the invention is as follows When the vacuum is applied to a curved sheet 22, the leakage is limited by the edges of the frame. flexible 17, and the assembly. (10-37) behaves like a hollow suction cup positively sucking the sheet 22 and straightening it at 23 while the frame 17 is folded over the periphery 12 as seen in FIG. 1. The straightened sheet 23 can therefore be drawn towards the front by the advance of the box 6, then be taken care of then by the driving rollers 7.
