Definitions
- the present invention relates to a device and a folding method for folding blanks of paper, cardboard, plastic, corrugated cardboard or similar material in a folder-gluer machine.
- the invention also relates to a folding tool for folding blanks of paper, cardboard, plastic, corrugated cardboard or similar material.
- a folder-gluer machine comprises a series of workstations, for example, a feeder feeding the production of the boxes cutting by cutting from a stack, an alignment module, a breaker precassing the first and third lines. longitudinal folding of the cut between 90 ° and 180 °, a folding module for folding at 180 ° the front legs of the cut, a sizing station, a folder for folding the second and fourth longitudinal fold lines of the cutter, a presser that compresses the second and fourth longitudinal fold lines, a transfer module that deposits the sheet boxes on a receiving module that receives the boxes while keeping them pressed to allow the glue to dry.
- the conveyance of the blanks from one station to another is carried out by means of belt conveyors which, by friction, grip the cuts between a lower conveyor and an upper conveyor.
- the lower conveyor is provided with lower belts while the upper carrier is provided with either upper belts or upper support rollers.
- the points of contact of the lower conveyor with the upper conveyor define the conveying path of the cuts.
- the cutouts can be held against the belts of the lower conveyor without the aid of upper conveyor.
- a cutter transport device without a higher carrier are disclosed in US4108302 and WO9714634.
- the lower conveyor is a conveyor with conventional belts cooperating with a vacuum chamber.
- a cutter transport device without a higher carrier is described in US4614512.
- the lower conveyor is a belt conveyor provided with suction elements.
- the lower conveyor generally comprises a plurality of longitudinal longitudinal members each supporting an endless conveyor belt guided by pulleys and rollers.
- Each spar is mounted in lateral sliding through bearings along one or more displacement slides fixed transversely between two longitudinal frames.
- the lateral displacement of each spar is ensured by one or more parallel screws mounted in rotation between the frames, the threaded portions of the screws being respectively engaged in transverse threaded orifices. spars.
- the folding of a front leg is usually done by means of a device comprising one or more elastic hooks hanging from a crosspiece placed above the passage plane of the cuts, the lower end of these hooks penetrating the plane of passage cuts, see for example US3285144.
- the elastic hook is animated by a tilting movement about a transverse axis between an initial position where the lower end of the hook is below the plane of passage of the cuts and a final position where the lower end of the hook is above the passage plane of the cutouts.
- the angle of tilting of the elastic hook varies depending on the length of the front leg and the length of the hook. Typically, for a front lug 30 mm long and a hook 80 mm long, the hook tilts at an angle of about 30 °.
- the hook is elastic in that it is provided with a return spring. The rocking movement is triggered by the passage of the cutouts that push the lower end of the hook.
- the initial position corresponds to the rest position of the elastic hook, in this position, the hook is across the passage of the blanks, so when a cut conveyed by the carrier arrives at the right of the device. folding, the leading edge of the cut pushes on the lower end of the hook, the hook switches to the final position by lifting the front leg in the space above the plane passing cutouts. By so rocking, the return spring accumulates energy, this accumulation becomes maximum when the hook reaches the final position. After the hook reaches the end position, the hook releases the front leg, which also releases the energy accumulated by the spring. The release of the energy of the spring causes the return of the elastic hook to the initial position.
- the return of the elastic hook to the initial position is in two stages. At first, the hook passes through the plane of passage of the cutouts where it is stopped by the longitudinal panel of the cutout located upstream of the front leg which has just been folded. Then, in a second step, the cutting continues to advance, the hook slides on the longitudinal panel to the rear edge of the cutout where it is released and ends its return stroke to the initial position.
- the folding cycle with an elastic hook is therefore a three-cycle cycle: a time to switch from the initial position to the end position and two times to switch from the end position to the initial position. This cycle is triggered at each passage of a cut by the action of the front edge of the cut on the hook, which is not satisfactory.
- Another problem relates to noise.
- the hook hits the longitudinal panel of a cut, a sound of shock is heard.
- the level of this noise varies with the speed of conveying the cuts and the material of the cut. For example, the impact noise on a cutout in corrugated cardboard is higher than the impact sound on a compact cardboard. Because of these shock noises, the working environment is degraded.
- the lifting finger is animated by a rocking movement about a transverse axis between an initial position where the finger is in position. Below the plane of passage of the cutouts and a final position where the finger passes through the plane of passage cuts to go above the cutout passage plan.
- the rocking movement of the finger is triggered by a cylinder synchronized with the passage of the cuts.
- a detector for example a photoelectric cell, generates a signal and sends it to the jack which switches the finger from the initial position to the final position.
- the finger pushes on the front leg which initiates a folding in the space above the passage plane cuts.
- This fold initiation allows the folding angle to go from 180 ° to about 150 °.
- the folding angle is the angle formed between the front leg and the adjacent longitudinal panel located upstream of the front leg.
- the folding finger toggles to the initial position, thus flipping, the front leg passes between the lifting finger and a fixed bending beam placed above the passage plane cutouts .
- folding device allows to limit the marks on the cuts and the noise caused by the sound of shock, the fact that it is placed under the passage plane cutouts while the front leg is folded in the space above the plane of passage of the cuts, that is to say the opposite of the folding device, limits the action of the folding tool, which requires the use of a cross folding to complete the folding of the front leg, which is not satisfactory.
- a first object of the invention is to overcome the aforementioned drawbacks by providing a device for folding paper blanks, cardboard, plastic, corrugated cardboard or similar material that avoids, at the same time, marking the blanks with a folding tool and the impact noises of the folding tool on the blanks, while avoiding placing the folding device opposite the space in which the front leg is folded.
- the invention relates to a folding device according to claim 1.
- a second object of the present invention is to provide a cut folding tool particularly suitable for the folding device according to the invention.
- the invention relates to a folding tool according to claim 6.
- a third object of the present invention is to provide a folding method for the implementation of a folding device according to the invention.
- the subject of the invention is a folding method according to claim 10.
- a fourth object of the present invention is to provide a folder-gluer machine equipped with a folding device according to the invention.
- the invention relates to a folder-gluer machine according to claim 15.
- the folding tool does not hit the cutouts, neither on the front edge, nor on the longitudinal panel located upstream of the front leg to bend, which avoids mark the cuts when folding the front legs. In the same way, the noise nuisance due to the noises of shock are eliminated.
- the device according to the invention avoids the use of a cross folding to achieve a complete folding of the front legs.
- the contact between the cuts and the bending tool is a point or rectilinear linear contact throughout the folding of the front legs, which ensures a perfect guiding of cutouts during said folding.

- the frame 1a is located on the opposite side to the conductor and the frame 1b is located on the driver's side.
- transversely parallel cylindrical movement slides 2 (only one slide is shown), pairs of parallel displacement screws 3 and a drive shaft mounted in rotation between the two frames (not shown).
- the slideways 2 are recessed at each of their ends to the frames 1a, 1b, they are intended to support three longitudinal longitudinal beams 6a, 6b, 6c mounted side by side and each supporting an endless conveyor belt 7 resting on a horizontal hard plane, plan consisting of a series of rollers 8.
- Each longitudinal spar is movable transversely between the frames 1a, 1b, along the displacement slide 2, this depending on the format of the blanks to be treated.
- Support devices cutouts against the conveyor belts 7 are arranged above certain portions of the longitudinal members 6a, 6b, 6c. These support devices may consist of a series of rollers held down by springs or an endless belt whose lower strand is pressed downwards.
- each spar is controlled by a pair of parallel screws 3 whose Threaded portions are respectively engaged in transverse threaded holes of the spar, which screws are fixed in translation but free in rotation between the frames 1a, 1b.

- FIGs 2a to 2c illustrate a known folding device and a carrier 1 similar to that described in connection with Figure 1.
- This device comprises two movable folding members 12 suspended at a crosspiece (not shown) placed above the passage plane of the blanks and two upper guides 11.
- Each folding member 12 comprises an elastic folding hook 13 consisting of a metal blade L-shaped. The lower end of the hook of folding 13 passes through the plane of passage of the cuts while the upper end of the folding hook is secured to a shaft 14 pivoting in a housing 15 about a transverse axis.
- a rigid rod 16 makes it possible to fix the casing 15 to the crossmember.
- a return spring housed in the housing 15 exerts on the shaft 14 a torque which tends to maintain the lower end of the hook 13 across the passage plane of the cuts.
- the front edge of the cut pushes on the hooks 13.
- the hooks 13 swing on their transverse axis, above the passage plane of the cutout 20.
- the tilting of the hooks causes at the same time the stressing of the springs housed in the housings 15
- the front legs 21 initiate folding by rising above the horizontal plane, that is to say in the space above the cut-out plane, while the remainder of the blank 20 is held against the conveyor belts 7 by any means known in the art, for example support devices as described above (not shown).
- the folding hooks 13 are brought back across the passage plane of the blanks under the action of their respective return spring.
- the return to the initial position is done in two stages. At first, the folding hook 13 passes through the plane of passage of the blanks where it is stopped by the longitudinal panel 22 located upstream of the front leg 21. Then, in a second step, the cutting continues to advance , the hook 13 slides on the longitudinal panel 22 to the rear edge 17 of the cutout where it is released and ends its return stroke to the initial position. A new folding cycle can then begin again as soon as a new cut is received.
- FIG. 3a to 3f schematically illustrate a folding device according to the invention in different phases of a folding cycle. This device cooperates with a conveyor (not shown) similar to that described with reference to FIG.
- the folding device comprises a movable folding tool 30 secured to a cross member (not shown) placed above the passage plane of the blanks.

- the movement of and the tool 30 is induced by an electric actuator for example a linear motor (not shown) comprising a vertical slide without freedom of rotation about the axis 4, controlled by optoelectronic reading means.
- a photocell 25 (shown only in FIGS. 3a and 3f) serves to detect the passage of a blank 20 '.
- the folding tool 30 consists of an elongate body 31 oriented vertically.
- the upper end of the elongated body 31 is coupled to the vertical slide of the linear motor while the lower end of the elongate body 31 is extended by a hook 32 ended by a rounded.
- the rounding forms a protrusion 33 at the end of the hook 32.
- the protuberance 33 has a spherical shape or a cylindrical shape with a transverse axis, so that seen in a longitudinal axial section plane, the protrusion 33 has a substantially circular section (see Figures 3a-3f).
- the opening of the hook 32 is turned in the opposite direction to that of the arrow 10 which indicates the running direction of the cuts.
- FIG. 3a shows the folding device according to the invention in a first phase corresponding to the beginning of a folding cycle.
- a cutout 19 ' leaves the folding device after being folded while the cutout 20' arrives in the folding device to be folded.
- the rear edge of the blank 19 ' is separated from the front edge of the blank 20' by a free space 'L'.
- the front edge 18 'of the blank 20' is detected by the photocell 25 located in upstream of the folding tool 30, a signal is sent to the control unit.
- the front lug 21 'and the longitudinal panel 22' of the blank are substantially in the same horizontal plane.
- the folding tool 30 is in the initial position, in this position, the folding tool 30 is outside the passage plane of the cuts. More specifically, the lower end of the folding tool 30, embodied by the protuberance 33, is located above the passage plane of the cuts.
- Figure 3b shows the same device as that of Figure 3a but in a subsequent phase corresponding to a certain time later in the folding cycle.
- the free space 'L' reaches the right of the folding tool 30, in this position, the control unit actuates the linear motor to lower the lower end of the folding tool 30 under the plan of passage of the cuts.
- the folding tool 30 passes through the free space 'L' without interacting with the cuts, that is to say without touching the cutouts 19 'and 20'.
- the folding tool 30 is across the passage plane of the cuts, this position corresponds to the final position of the folding tool.
- the control unit actuates the linear motor to raise the lower end of the folding tool 30 at the passage plane of the cutouts so that the end lower part of the folding tool 30 bears on the cutout 20 '.
- the protuberance 33 bears on the underside 20b 'of the cutout 20' near the front edge 18 ', at a distance' d 'from the transverse fold line 24' of the front lug 21 '(see FIG. 3d).
- the lower face 20b ' is the face of the blank 20' facing the space below the passage plane of the blanks.
- the contact between the cut 20 'and the folding tool 30 is, at each instant of folding of said front lug 21', a point or rectilinear linear contact that which ensures perfect guidance of the cutout 20 'throughout the folding of said front lug 21'.
- the folding angle ⁇ is less than 150 °.
- the folding angle ⁇ is less than 90 °.
- the angle of folding ⁇ is the angle formed between the front lug 21 'and the adjacent longitudinal panel 22'.
- the folding tool 30 returns to the initial position, the cut 20 'leaves the folding device after being folded while a new cut 23' arrives in the device of folding to be folded.
- a new folding cycle is triggered each time a cut is made, more specifically, at each Once the leading edge of a cut is detected by the photocell 25.
- the vertical reciprocating movement of the folding tool 30 is in synchronism with the passage of the cuts.
- the distance 'd' is calculated by the computing unit which transmits it to the control unit to control the distance 'd throughout the folding of the front legs.
- the distance 'd' is chosen as large as possible at the beginning of folding to have a maximum leverage effect on the front lug 21 'and thus facilitate its folding around the transverse fold line 24'.
- the distance 'd' at the beginning of folding is equal to about 75% of the length of the front leg 21 '.
- the distance 'd' may be different depending on the rigidity of the cut. Indeed, for a low stiffness cutting such as a paper or cardboard cut, it is preferable to reduce the distance 'd' during folding so as to prevent the front leg 21 'bends without folding, while that for a cutting of high rigidity such as a plastic cut or corrugated cardboard, it is preferable to keep the distance 'd' during folding so as to keep maximum leverage on the front leg 21 '.
- the example illustrated above shows a folding device comprising a single folding tool, it goes without saying that the number of folding tool depends on the number of front legs to bend, so for a cut with two front legs to bend, the device will include two folding tools.
- the back and forth movement of the folding tool can be provided by a rod / crank system (not shown).
- the movement of the folding tool is not necessarily a vertical back and forth movement.
- it may be a oblique back and forth motion or pivoting movement about an axis.
- the example illustrated above shows a passage plan of the cuts whose surface is flat, the invention is not limited to this example, the surface of the passage plane of the blanks may be curved.
