- Cigarette packing machines are known to employ a device for feeding sheets to a wrapping line as described in US Patent no. 4,918,908, whereby a suction pickup roller is rolled over and winds up a sheet located at the bottom opening of a hopper containing a stack of sheets. Once the sheet is wound fully, the pickup roller is arrested in a release position to release the sheet to an input conveyor of a wrapping line, which input conveyor is normally defined by two pickup rollers parallel and tangent to each other to engage the sheet in between.
- CH Patent no. 288,604 discloses a device for feeding sheets to a working line, whereby a suction pickup roller is rolled over and winds up a sheet located at the bottom opening of a hopper containing a stack of sheets; during the rolling of the suction pickup roller, the sheet partially wound up by the suction pickup roller is fed to a subsequent conveyor.
- US Patent no. 3,127,167 discloses a device for feeding sheets to a working line whereby a suction pickup roller is rolled over and winds up a sheet located at the upper opening of a hopper containing a stack of sheets. Once the sheet is wound around the suction pickup roller, such sheet is fed from the suction pickup roller to the working line.
- feed devices of the above type tend to severely stress and damage the sheets at relatively high operating speeds typical of modern packing machines, and particularly when releasing the sheets from the pickup roller to the input conveyor of the wrapping line.
- the present invention also relates to a device for feeding sheets to a wrapping line.
- Number 1 in Figure 1 indicates as a whole a device for feeding sheets 2 to a wrapping line 3 (shown only partly) of a known cigarette packing machine (not shown). More specifically, sheets 2 are labels, each of which is applied by wrapping line 3 to the outside of a respective packet of cigarettes (not shown).

- Feed device 1 also comprises two suction pickup rollers 8, each having a respective axis 9 perpendicular to the Figure 1 plane, and each activated by a common actuating device 10 to withdraw a respective sheet 2 in pickup position 7, and to feed sheet 2 to a respective intermediate suction roller 11 having an axis 12 parallel to axes 9. From intermediate rollers 11, sheets 2 are transferred in known manner to a single suction input roller 13 of wrapping line 3 and then applied to respective packets of cigarettes (not shown).
- the above pickup rollers 8 may be replaced by different known rotary pickup members of other than substantially cylindrical shape.
- actuating device 10 imparts to each pickup roller 8 a rolling movement in contact with a respective sheet 2 in pickup position 7, so as to at least partly wind each sheet 2 about respective pickup roller 8.
- the rolling movement is imparted to each pickup roller 8 by actuating device 10 moving each pickup roller 8 in a traveling direction 14 perpendicular to respective axis 9, and at the same time rotating each pickup roller 8 about respective axis 9.
- Actuating device 10 then imparts to each pickup roller 8 a further rolling movement in contact with respective intermediate roller 11 to assist release of respective sheet 2 to respective intermediate roller 11; the rolling movement is imparted to each pickup roller 8 by combining a rotation of each pickup roller 8 about respective axis 9 with a rotation of respective intermediate roller 11 about respective axis 12. During release of each sheet 2 from respective pickup roller 8 to respective intermediate roller 11, each pickup roller 8 is rotated at the same surface speed but in the opposite direction with respect to respective intermediate roller 11.
- each intermediate roller 11 is replaced by a different type of intermediate conveyor.
- each pickup roller 8 continues rotating about respective axis 9 to assist release of respective sheet 2 to the corresponding intermediate conveyor.

- each pickup roller 8 rotates continuously and substantially uninterruptedly anticlockwise about respective axis 9, whereas, in the course of the return stage, each pickup roller 8 rotates clockwise about respective axis 9.
- each sheet 2 is wound completely about respective pickup roller 8, which then rotates about respective axis 9 until sheet 2 is released completely to respective intermediate roller 11.
- each pickup roller 8 only rotates about respective axis 9 until an initial portion of respective sheet 2 has been transferred to corresponding intermediate roller 11.
- Pickup rollers 8, intermediate rollers 11 and input roller 13 are known suction rollers, each of which gradually activates suction through its lateral surface during pickup of respective sheet 2, and gradually deactivates suction through its lateral surface during release of respective sheet 2.
- each suction pickup roller 8 comprises a cylindrical inner body 15 having a suction chamber 16 connected to a suction pump (not shown), and a release chamber 17 connected to the outside environment; and a cylindrical outer shell 18, which is coaxial with cylindrical inner body 15, rotates with respect to cylindrical inner body 15, and has a respective lateral surface 19 having a number of through holes 20 and for receiving said sheet.
- holes 20 communicate cyclically with chambers 16 and 17 to gradually and respectively activate and deactivate suction through lateral surface 19.
- each sheet 2 is therefore subjected to very little stress, by virtue of respective roller 8 rotating about respective axis 9 and so enabling roller 8 to accompany respective sheet 2 onto respective intermediate roller 11.
- actuating device 10 comprises a frame 21 supporting each pickup roller 8 for rotation about respective central axis 9; an actuating device 22 for moving frame 21 back and forth linearly in traveling direction 14; and an actuating device 23 for oscillating each pickup roller 8 about respective central axis 9.

Description
- The present invention relates to a method of feeding sheets to a wrapping line.
- The present invention may be used to advantage for feeding sheets to a wrapping line of a cigarette packing machine, to which the following description refers purely by way of example.
- Cigarette packing machines are known to employ a device for feeding sheets to a wrapping line as described in US Patent no. 4,918,908, whereby a suction pickup roller is rolled over and winds up a sheet located at the bottom opening of a hopper containing a stack of sheets. Once the sheet is wound fully, the pickup roller is arrested in a release position to release the sheet to an input conveyor of a wrapping line, which input conveyor is normally defined by two pickup rollers parallel and tangent to each other to engage the sheet in between.
- CH Patent no. 288,604 discloses a device for feeding sheets to a working line, whereby a suction pickup roller is rolled over and winds up a sheet located at the bottom opening of a hopper containing a stack of sheets; during the rolling of the suction pickup roller, the sheet partially wound up by the suction pickup roller is fed to a subsequent conveyor.
- US Patent no. 3,127,167 discloses a device for feeding sheets to a working line whereby a suction pickup roller is rolled over and winds up a sheet located at the upper opening of a hopper containing a stack of sheets. Once the sheet is wound around the suction pickup roller, such sheet is fed from the suction pickup roller to the working line.
- Though satisfactory at relatively low operating speeds, feed devices of the above type tend to severely stress and damage the sheets at relatively high operating speeds typical of modern packing machines, and particularly when releasing the sheets from the pickup roller to the input conveyor of the wrapping line.
- It is an object of the present invention to provide a method of feeding sheets to a wrapping line, designed to eliminate the aforementioned drawbacks, and which is also straightforward and cheap to implement.
- According to the present invention, there is provided a method of feeding sheets to a wrapping line as recited by
Claim 1. - The present invention also relates to a device for feeding sheets to a wrapping line.
- According to the present invention, there is provided a device for feeding a sheet to a wrapping line as recited by

Number 1 in Figure 1 indicates as a whole a device forfeeding sheets 2 to a wrapping line 3 (shown only partly) of a known cigarette packing machine (not shown). More specifically,sheets 2 are labels, each of which is applied by wrappingline 3 to the outside of a respective packet of cigarettes (not shown). -
Feed device 1 comprises twovertical hoppers 4, each containing arespective stack 5 ofsheets 2, and each having a respective bottom output opening 6 defining a pickup position 7 ofsheets 2. -
Feed device 1 also comprises twosuction pickup rollers 8, each having arespective axis 9 perpendicular to the Figure 1 plane, and each activated by acommon actuating device 10 to withdraw arespective sheet 2 in pickup position 7, and to feedsheet 2 to a respectiveintermediate suction roller 11 having anaxis 12 parallel toaxes 9. Fromintermediate rollers 11,sheets 2 are transferred in known manner to a singlesuction input roller 13 ofwrapping line 3 and then applied to respective packets of cigarettes (not shown). Theabove pickup rollers 8 may be replaced by different known rotary pickup members of other than substantially cylindrical shape. - As shown in Figure 4, in actual use, actuating
device 10 imparts to each pickup roller 8 a rolling movement in contact with arespective sheet 2 in pickup position 7, so as to at least partly wind eachsheet 2 aboutrespective pickup roller 8. The rolling movement is imparted to eachpickup roller 8 by actuatingdevice 10 moving eachpickup roller 8 in a travelingdirection 14 perpendicular torespective axis 9, and at the same time rotating eachpickup roller 8 aboutrespective axis 9. - Actuating
device 10 then imparts to each pickup roller 8 a further rolling movement in contact with respectiveintermediate roller 11 to assist release ofrespective sheet 2 to respectiveintermediate roller 11; the rolling movement is imparted to eachpickup roller 8 by combining a rotation of eachpickup roller 8 aboutrespective axis 9 with a rotation of respectiveintermediate roller 11 aboutrespective axis 12. During release of eachsheet 2 fromrespective pickup roller 8 to respectiveintermediate roller 11, eachpickup roller 8 is rotated at the same surface speed but in the opposite direction with respect to respectiveintermediate roller 11. - In an alternative embodiment not shown, each
intermediate roller 11 is replaced by a different type of intermediate conveyor. In the alternative embodiment, oncerespective sheet 2 has been picked up, eachpickup roller 8 continues rotating aboutrespective axis 9 to assist release ofrespective sheet 2 to the corresponding intermediate conveyor. - As each
sheet 2 is fed fromrespective hopper 4 to respectiveintermediate roller 11, therefore, actuatingdevice 10 moves saidpickup roller 8 indirection 14 according to a given law of motion comprising an initial forward stage (shown in Figures 4a and 4b) to pick upsheet 2 and bringpickup roller 8 into a release position tangent to respectiveintermediate roller 11; a hold stage (shown in Figures 4c and 4d) to releasesheet 2 tointermediate roller 11, and wherein thecentral axis 9 of rotation ofpickup roller 8 is maintained in a fixed position; and a final return stage (shown in Figure 4e). - In the course of the forward and hold stages, each
pickup roller 8 rotates continuously and substantially uninterruptedly anticlockwise aboutrespective axis 9, whereas, in the course of the return stage, eachpickup roller 8 rotates clockwise aboutrespective axis 9. - In the preferred embodiment shown in the accompanying drawings, each
sheet 2 is wound completely aboutrespective pickup roller 8, which then rotates aboutrespective axis 9 untilsheet 2 is released completely to respectiveintermediate roller 11. In an alternative embodiment, eachpickup roller 8 only rotates aboutrespective axis 9 until an initial portion ofrespective sheet 2 has been transferred to correspondingintermediate roller 11. -
Pickup rollers 8,intermediate rollers 11 andinput roller 13 are known suction rollers, each of which gradually activates suction through its lateral surface during pickup ofrespective sheet 2, and gradually deactivates suction through its lateral surface during release ofrespective sheet 2. - For example, as shown in Figure 4a, each
suction pickup roller 8 comprises a cylindricalinner body 15 having asuction chamber 16 connected to a suction pump (not shown), and a release chamber 17 connected to the outside environment; and a cylindricalouter shell 18, which is coaxial with cylindricalinner body 15, rotates with respect to cylindricalinner body 15, and has a respectivelateral surface 19 having a number of throughholes 20 and for receiving said sheet. As cylindricalouter shell 18 rotates,holes 20 communicate cyclically withchambers 16 and 17 to gradually and respectively activate and deactivate suction throughlateral surface 19. - During transfer from
respective pickup roller 8 to respectiveintermediate roller 11, eachsheet 2 is therefore subjected to very little stress, by virtue ofrespective roller 8 rotating aboutrespective axis 9 and so enablingroller 8 to accompanyrespective sheet 2 onto respectiveintermediate roller 11. - As shown in Figure 1,
actuating device 10 comprises aframe 21 supporting eachpickup roller 8 for rotation about respectivecentral axis 9; anactuating device 22 for movingframe 21 back and forth linearly in travelingdirection 14; and anactuating device 23 for oscillating eachpickup roller 8 about respectivecentral axis 9. -
