- the present invention relates to the field of printers and copiers and in particular a receiving sheet feeding and feeding apparatus which one Suction tape feed mechanism includes where the top sheet of a stack is curled is, as well as an overpressure air separation device, as in such printers and Copiers are provided.
- This invention is useful for the device disclosed in US 5,344,133.
- the patent mentioned relates to one Vacuum air supply, a first pressurized air supply and a second About compressed air supply. The first and the second pressurized air supply used simultaneously and collectively referred to herein as an air knife.
- the suction belt feed mechanism described in the mentioned document is for separating the top sheet from a sheet supply stack during the Feed cycle can be used.
- the airflow and the Vacuum levels and the associated timing from the largest Feed speed specified by the feed mechanism i.e. one feed for each image frame from the same stock.
- Operation mode When inserting cover sheets and insertion sheets for example, generally a number of regular sheets between the Slip sheets advanced.
- Many printers work in a similar way "Interleaf mode" when printing double-sided, with every other feed from that Paper supply mechanism comes and sheets are pushed in between the duplex path become. In these and similar cases, a method is desired in which the upper sheet is not separated according to the cycle from the sheet supply stack, so that Increase the likelihood that the next sheet will be fed if desired.
- the object of this invention is to provide an improved method to create mentioned type, which ensures in a safe manner, which always only the top sheet of a stack is transported. This task is done with a procedure solved according to claims 1. Further features of the invention are in the subclaims contain.
- a method according to the invention for operating a suction belt feed mechanism where the top sheet of a stack is curled and the one Can have overpressure air separation device at a cycle time at which no Feed takes place to separate a sheet from a sheet supply stack, provides that the top sheets in the stack by activating the vacuum air and / or the Overpressure air is shaken at the time of the cycle at which no feed takes place.
- US 5,344,133 describes an apparatus that both vacuum air and Over air pressure is used to separate the top sheet from a supply stack and collect.
- both the vacuum air line and the Pressurized air line passed through valves that control vacuum air flow and Overpressure air flow can be used.
- both the vacuum air valve] and the pressure air valve during the Feed cycle open and closed if there is no feed operation on the supply is carried out.
- large sheet sizes e.g. 11 x 17 inch (27.94 x 43.16cm)
- double-sided copies or sheets from several stocks e.g. raw paper, Cover pages and inserts
- This time can be used to Feed reliability for the next sheet from the specified stock to be advanced. Accordingly, the present disclosure Invention some ways in which this can be done.
- the detailed description relates to a suction belt feed device in which the top sheet of a stack is curled and provides sheet feed from above; however, the present invention can also be used in a suction belt feed device Sheet feed from below can be used.
- the vacuum air also separates or without an air knife, not the upper arch, but the lower one.
- FIGs. 1 through 6 show a receiving sheet feeding and feeding apparatus 10, an open magazine 12 and a lifting platform 14 for holding a stack of sheets includes.
- a sheet stack 15 held by the platform 14 contains individual ones Sheets that are suitable as receiving sheets to be placed on a copying machine or to make reproductions on a printer.
- the sheet stack-carrying platform 14 is a lifting mechanism, the one in Performs essentially vertical lifting movement, held in the magazine 12.
- the lifting mechanism serves to raise the lifting platform 14 to such a height that the top sheet of the stack during operation at a predetermined level is held.
- the uppermost sheet is turned on by means of a sheet detection switch 80 (see Fig. 5) or kept at the predetermined level by means of several switches, wherein the switch controls a motor to operate the lifting mechanism by which the Platform is raised until one or more switches are activated.
- a sheet feed head assembly 30 is so in connection with the magazine 12 arranged to be spaced apart over a portion of the lifting table 14 Relationship to a sheet stack 15 which is carried by the lifting table 14.
- the sheet feed head assembly 30 includes an apertured chamber 32 that is connected to a vacuum air source 31, and an air knife 40, which by a Pressure air valve 60 is connected to a pressure air source 41.
- a Air knife 40 overpressure air nozzle lifts the top bow of the supported Sheet stack 15 on.
- the vacuum air acts on the through the chamber openings 33 Chamber 32 such that the top-most raised sheet of the stack then separates is seized by the sheet stack 15 on the chamber 32. Therefore the top sheet sticks due to the openings 37 of the band on the band 36. Additional pressure air nozzles of the Air knife 40 ensure that subsequent sheets from the gripped top sheet be separated.
- a vacuum air valve 38 (see Fig. 5) is used to control the vacuum air used. So during a pull-in cycle, the valve is open around the top arc to float in the stack. In a preferred method, opening and Closing of the vacuum air valve is time-controlled, but the operation of the valve can also controlled by other methods, e.g. by pressure or mechanical operated switch.
- a switch can, for example, on the vacuum air chamber 32 Detect a sheet detection attached.
- a signal that the switch at Identification of a sheet detection output can be used to operate the control various components of the sheet feed head assembly 30, e.g. to Time operations or airflow level adjustment to operate for a certain type of sheet (size) which is provided by the sheet supply and feed mechanism 10 to be transported to optimize.
- the air knife 40 has a first air jet arrangement 42 and a second Air jet arrangement 44.
- the first air jet assembly 42 includes a single one Nozzle 43, which is in fluid communication with a source 41 of pressurized air, for example in a range from 1,000 to 2,500 Pa (approx. 4 to 10 inwg) in certain Embodiments.
- the chambers that are part of the first air jet assembly 42 and the second air jet arrangement 44 can be separate chambers or one larger chamber.
- the nozzle 43 aligns a jet Air pressure on the sheet stack in the middle of the leading edge to the upper sheet in the stack to bring the top sheet into engagement with the Bring sheet feed head assembly 30 where it is due to the vacuum air at the Vacuum air chamber 32 can be detected.
- the second air jet assembly 44 includes a plurality of nozzles 46 that are shown in FIG Stand in fluid communication with the pressurized air source 41.
- the nozzles 46 are just above the alignment point for the first air jet nozzle 43.
- the purpose of the is the second air jet arrangement 44, possibly on the Sheet feed head assembly 30 captured top sheet to separate adhering sheets.
- a nozzle for pressurized air 60 is used to control the pressurized air flow through the Air knife 40 used.
- overpressure air separation device 40 When overpressure air separation device 40 is activated means that the relief air valve 60 is open. If the Overpressure air separation device 40 is deactivated, it means that the Pressure air valve 60 is closed. When the air relief valve 60 is closed, however, this does not necessarily mean that there is no pressurized air flow. In a preferred embodiment, the overpressure air valve 60 also allows one certain airflow when it is closed (it does not close completely). A common one Valve shape allows a third of the airflow that flows through an open valve flows through the valve when it is "closed".
- the present invention is not based on restricts a suction tape feeding mechanism in which the top sheet is a Stack is corrugated and which has an overpressure air separation device 40; she can can also be used in a suction belt feed mechanism with the top one Sheet of a stack is corrugated and no overpressure air separation device 40 is provided is.
- the procedure is the same except that in the places of the Description where it is noted that the vacuum air and the Pressurized air separation device are activated, only the vacuum air is activated.
- a method for operating a Suction belt feed mechanism in which the top sheet of a stack is curled and having an overpressure air separator 40, shaking the top sheets in the sheet supply stack 15 at a point in time at which no feed takes place Activate the vacuum air and the pressure air separation device 40 to an arc to be separated from a sheet supply stack 15.
- the vacuum air and air knife 40 remain (Pressurized air separator 40) activated until the feed cycle begins. If the Feed cycle begins, the vacuum air and the air knife 40 return Control sequence of the feed cycle back.
- the vacuum air and the Air knife 40 activated for each frame and deactivated as if a feed process was carried out, but the The tape feed mechanism is not engaged.
- the vacuum air and the air knife 40 again return to the control sequence of the feed cycle back.
- the vacuum air and the Pressurized air separator 40 for the frame that is immediately on the last feed follows, deactivated and not reactivated until the feed cycle begins.
- Another Embodiment of this method is used to the upcoming feed identify and the negative pressure air and positive pressure air separation device 40 during of the last frame before the forthcoming feed starts.
