Abstract
A ream (2) is selected and separated from a stack
(3) of sheets (4) by means of a separating member (16)
which is inserted inside the stack (3) at an insertion
region (18) defined by images acquired by a television
camera (10) moved vertically to scan a given scanning
region (12) of the stack (3); the television camera (10)
and the separating member (16) being so oriented with
respect to each other that the insertion region (18) lies
in the scanning region (12).
Description
- The present invention relates to a unit for selecting and separating reams from a stack of sheets of paper or similar.
- More specifically, the present invention relates to a unit for selecting and separating reams from a stack of sheets, of the type comprising a television camera movable in a substantially vertical direction along the stack to acquire images of the sheets at a given scanning region; and a separating member which is inserted inside the stack to separate the reams successively from the stack.
- The images acquired by the television camera are used by an electronic central control unit to control the movement of the separating member in said vertical direction, to count the number of sheets in a ream during said movement of the separating member, and to arrest the separating member at the last sheet in the ream to be removed.
- Once positioned at the last sheet in the ream to be removed, the separating member is moved into contact with the stack at a given insertion region, and is inserted inside the stack to separate the ream from the stack.
- Known units of the type described above have various drawbacks, mainly on account of the television camera and the separating member being so oriented with respect to each other that the scanning region, where the television camera acquires the sheet images used by the electronic central control unit to count the sheets as the separating member moves in the vertical direction, and the insertion region, where the separating member is inserted inside the stack, are distinct regions located a given distance apart.
- Consequently, the unit only operates correctly, i.e. the insertion region is only positioned correctly at the last sheet in the ream to be removed, when the sheets have a perfectly flat profile. Conversely, in the event of an undulated sheet profile, the separating member may be inserted inside the stack at a sheet other than the one counted as the last sheet in the ream at the scanning region, and so remove a ream comprising more or fewer than the correct number of sheets.
- It is an object of the present invention to provide a unit for selecting and separating reams from a stack of sheets of paper or similar, designed to eliminate the aforementioned drawbacks, and which is cheap and easy to produce.
- According to the present invention, there is provided a unit for selecting and separating reams from a stack of sheets of paper or similar, as claimed in Claim 1.
- A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a schematic view in perspective, with parts removed for clarity, of a preferred embodiment of the unit according to the present invention;
- Figure 2 shows a first schematic side view, with parts removed for clarity, of the Figure 1 unit;
- Figure 3 shows a second schematic side view, with parts removed for clarity, of the Figure 1 unit.
-
- Number 1 in the accompanying drawings indicates as a whole a unit for selecting and separating
reams 2 from astack 3 ofsheets 4 supported on a pallet 5 and comprising a number ofsheets 4 stacked in avertical direction 6. - Unit 1 comprises an optical image-
acquisition device 7 positioned facing afront face 8 ofstack 3, and in turn comprising a first slide (not shown) movable indirection 6; a second slide (not shown) connected in known manner to the first slide (not shown) to move linearly in ahorizontal direction 9 crosswise todirection 6; and atelevision camera 10 mounted on the second slide (not shown), having anoptical axis 11 parallel todirection 9, and for covering a given portion offace 8. - By moving
television camera 10 indirection 6, the portion offace 8 covered bytelevision camera 10 can be varied to define, onface 8, a givenscanning region 12 which can be illuminated by alight source 13. - In connection with the above, it should be pointed out that, in the example shown,
direction 9 and, therefore,axis 11 form an angle a of other than 0° with ahorizontal direction 14 perpendicular toface 8, which, unless otherwise stated, will be considered a flat face parallel todirection 6. - Unit 1 also comprises a
separating device 15 for separatingreams 2 fromstack 3, and which in turn comprises a first slide (not shown) movable indirection 6; a second slide (not shown) connected in known manner to the first slide (not shown) to move linearly indirection 14; and a separatingmember 16 mounted on the second slide (not shown). -
Member 16 is defined by a substantially flat, wedge-shaped blade 17 which is inserted insidestack 3 at a substantially spot-shaped insertion region 18 lying inscanning region 12 oftelevision camera 10, and whose location onface 8 is indicated, whenblade 17 is located a given distance fromface 8, by a laser pointing device 19 integral withmember 16 and for illuminating a portion offace 8 coincident withregion 18. - In actual use,
television camera 10 is moved indirection 6 to acquire, within scanningregion 12, the images of a number ofsheets 4 normally approximating in excess the number ofsheets 4 in aream 2. The images acquired bytelevision camera 10 are used by an electroniccentral control unit 20 to control the movement ofblade 17 and, therefore, ofinsertion region 18 indirection 6, to countsheets 4 asblade 17 moves indirection 6, and to arrestblade 17 indirection 6 onceblade 17 is positioned at thelast sheet 4 in theream 2 to be selected and removed. - At this point,
blade 17 is moved indirection 14 and inserted insidestack 3 atregion 18 to separate theream 2 considered fromstack 3. - Since
television camera 10 andblade 17 are so oriented with respect to each other thatinsertion region 18 lies in scanningregion 12,insertion region 18 is always located within the portion offace 8 covered bytelevision camera 10. Consequently, whenblade 17 is arrested indirection 6,insertion region 18 is always located correctly at thelast sheet 4 in theream 2 to be removed, regardless of the shape ofsheets 4, i.e. regardless of whether the profile ofsheets 4 is perfectly flat or undulated. - Since
face 8 may possibly be undulated, i.e. other than perfectly flat,central control unit 20 also provides, astelevision camera 10 moves indirection 6, for continuously feedback-controlling the movement oftelevision camera 10 indirection 9 in response to a signal from adistance sensor 21 integral withtelevision camera 10. Movingtelevision camera 10 indirection 9 provides for maintaining a substantially constant distance, measured parallel todirection 9, betweenface 8 andtelevision camera 10, and so enablingtelevision camera 10 to acquire correct images ofregion 12, i.e. to correctly focus the images ofregion 12. - Obviously, in variations not shown:
-
television camera 10 andblade 17 may be oriented with respect to each other in any manner capable of ensuringinsertion region 18 lies in scanningregion 12; -
television camera 10 is fixed indirection 6, andstack 3 is movable indirection 6; -
television camera 10 is mounted toscan sheets 4 by oscillating about a given axis of rotation; and -
television camera 10 is replaced by a laser sensor for determining a profile ofsheets 4 instack 3 atscanning region 12. -
