Description

  The present invention provides an apparatus (generally also referred to as a feeder) for supplying a sheet of paper or cardboard, which is provided with the features of the premise of claim 1, to a processing machine, that is, a paper stack having a conveying device A sheet feeder standing on one side is supplied to the paper separation device by the transport device, the paper stack is divided, and the fixed portion and the rotation axis are swung around. 19. A method of feeding bar- or bundle-like sheets as claimed in claim 18, which relates to a device for feeding sheets, comprising a movably supported part. That is, the present invention relates to a method of supplying a bar-shaped or bundle-shaped sheet to a device that supplies a sheet of paper or cardboard to a processing machine.

  For example, as described in Patent Document 1, the feeder has not only a magazine but also a paper separating device. Sheets to be loaded into the processing machine are prepared in the magazine. The drum of the paper separating device acts to separate the sheets one by one and pass them one by one to the processing device. When the processing apparatus is a collapsible binding machine, signatures are sent one by one from a plurality of feeders to the collation chain, and in this way, a brochure (temporary binding book) to be bound is formed.

  Various types of feeders are known from the prior art, for pile feeders made of individual sheets, bundled bar-shaped sheet feeders, for small sealed bar-shaped sheets Such feeders as so-called bundled sheets of paper are known. Patent Document 2 shows a horizontally placed sheet feeder provided with a printed sheet magazine and a paper separating device. The printed sheet is inserted horizontally into the printed sheet magazine. For the purpose of paper separation, the bottom sheet is pulled out by the drum type feeder. The disadvantage of this process is that the number of printed sheets that can be inserted into the printed sheet magazine is greatly limited. If the number of printed sheets is too large, the pressing force on the bottom sheet caused by gravity becomes too high, so that the sheet can no longer be pulled out. In order to be able to operate such a horizontally placed sheet feeder in a continuous operation, the printed sheets must be manually inserted into the magazine at short time intervals.

  For example, in a vertical-type sheet feeder as described in Patent Document 3, more sheets can be loaded in a magazine. The bottom edge of the sheet rests on the bottom of the magazine in the horizontal direction or slightly tilted. The first sheet is pulled out by the paper separating device and supplied to the processing device. The disadvantages of this type of feeder are that the magazine cannot accommodate bar- or bundle-like sheets formed by a folding machine, and that new sheets are frequently manually loaded into the magazine. It must be. At this time, the magazine is usually at an unfavorable ergonomic height.

  In addition to the horizontal-type sheet feeder and the vertical-type sheet feeder described above, a bar-shaped sheet as formed by a folding machine can be accommodated as it is. Two types of feeders are used. Patent document 4 accepts a sheet of paper as a bar-shaped sheet in the rear conveyance section, further conveys the sheet in a relaxed region, and supplies it as a pile to a paper separating device. A sheet feeder is disclosed. In the pile state, the sheet is standing vertically with its one side down. A crane is used to load the bar-shaped sheet feeder into the bar-shaped sheet feeder. Providing not only a crane and a crane track but also a bar-like sheet feeder itself results in a large required space and a high input cost.

Yet another aspect of the feeder is a combination of a horizontally placed sheet feeder and a so-called stream feeder, as described in Patent Document 5, for example. Similar to the bar-shaped sheet feeder, the stream feeder is loaded with bar-shaped sheets. Individual sheets are further conveyed to a horizontally placed sheet feeder by a conveyor belt, where a pile of a certain height is prepared. The disadvantages of this embodiment are that, as described above, it is necessary to provide a crane track, and a large required space and a high input cost are generated.
