Definitions

  • the invention relates to a stacking device according to the features of claim 1.
  • Stacking devices of the type mentioned are known from DE-C 31 15 511. This is a storage device for a pre-folded paper web in a paper stacker of a high-speed printing device, in which the paper web is stacked on a paper storage surface.
  • the paper storage area is designed to be pullable in a drawer-like manner from the housing area of the printer and has a telescopic guide profile system on the side.
  • the known device is designed so that it is designed to be insensitive to transverse forces, so that even large and heavy stacks of paper can be removed freely through the housing without hindrance.
  • the paper stack is near the floor when the paper storage surface is pulled out. This is ergonomically unfavorable, because these stacks of paper have to be lifted for the further transport of the printed paper stacks. This is cumbersome and unwieldy because of the weight of the paper stack.
  • thermal printing device which is designed in the form of a journal printer.
  • the thermal printing device is removably arranged in a piece of furniture in the form of an operating table. It consists of a support container with a pressure device arranged therein.
  • the support container contains built-in paper storage areas for receiving the printed record carrier and for receiving the unprinted record carrier.
  • a lever device arranged below the support container enables it to extend the support container together with the printing device from the operating table.
  • the printing device is thus accessible from all sides, which facilitates the service of the printing device and the insertion and removal of the recording medium.
  • the lever device itself consists of two levers arranged in the manner of a parallelogram, which are articulated on the one hand on the support container on the other hand on the piece of furniture.
  • a spring assigned to the levers supports the lifting of the pressure device from a retracted position into a locked service position.
  • the object of the invention is to design a stacking device of the type mentioned at the outset in such a way that it can be integrated within a rapid printing device with little effort and which enables an ergonomically optimal removal of the stack.
  • the stacking device has a guide system which is designed such that it enables the paper storage surface to be extended from a storage position located in the housing area to a removal position protruding from the housing area with an adjustable height of the removal position relative to the storage position, makes it possible to remove the printed stack particularly simple and ergonomically favorable.
  • the paper storage area is pivoted out of the device without changing the storage height, e.g. extend the stack under the stacking frame (storage device).
  • This removal position is e.g. advantageous if lower transport trolleys are used, which have approximately the height of the paper storage area, so that the stacks can be pushed in a simple manner from the paper storage area onto the loading area of the trolley.
  • the operator can swing out the paper storage surface, which is designed in the form of a swing-out lifting table, by a motor to a presettable height. In order to obtain the removal position that is favorable for him, the operator can freely select this removal height. This is particularly important if e.g. Conveyor belts or paper post-processing machines such as Paper cutting devices are provided.
  • the entire stacking device can be easily and space-saving within a rapid printing device that e.g. can be an electrophotographic printing device.
  • the stacking device is designed in accordance with DE-PS 31 15 511 so that the paper storage surface is designed to be stationary, while the storage device is raised by a drive device with increasing height of the paper stack.
  • the stacking device according to the invention can be integrated in a particularly simple manner in an electrophotographic printing device in such a way that the stacking device is located within the layout of the printer without having to make any significant structural changes to the actual stacking device with storage aids, feed channel, etc.
  • the stacking device can also be used to process single sheets in printing devices. All that is required is an appropriately adapted storage device (forklift frame).
  • An electrophotographic printing device not described in detail here has a recess 11 in which a stacking device is provided for receiving the pre-folded continuous paper web printed in an electrophotographic process.
  • the stacking device contains a paper storage surface 12 on which the printed continuous paper 13 is deposited and a depositing device 14 which is raised with the height of the paper stack with the aid of a drive device, not shown here, and a guide channel 15 which changes its length depending on the movement of the depositing device.
  • the storage device can be designed according to DE-PS 31 15 511.
  • the paper storage surface 12 is held and guided via a swivel lever 16 arranged on one side on the inside of the paper storage surface.
  • This is rotatably attached to the inner surface of the recess 11 via a first fixed pivot point 17 and to the paper storage surface 12 via a second free pivot point 18 stands in the area of the first fixed fulcrum 17 via a shaft 19 with a motor 20 with associated gear 21.
  • a lifting cylinder (hydraulic) or a lifting spindle can also be arranged.
  • the pivoting direction and the pivoting stroke can be preset via an operating panel 22, the operating panels being constructed in the usual way.
  • the motor 20 can, for example, be coupled to a clock disk and the control panels 22 can contain storage elements for the number of revolutions to be controlled and the direction of movement.
  • these consist of a round element 23 which is arranged in the region of the first fixed pivot point 17 and is fastened, for example by screws 24, to the housing of the printing device in the recess 11.
  • a second round element 25 which is fixedly connected to the paper storage surface 12.
  • This round element has an axis 26 which is fixedly connected to the paper storage surface 12.
  • the first and second round elements (23, 25) are coupled via kinematics (eg band-shaped element) 27, for example in the form of a chain, the ends of the chain 26 being attached to the circumference of the round elements by means of screws 27, for example.
  • the chain is arranged so that when the paper storage surface 12 is pivoted upwards via the pivoting lever 16, the chain is released in the region of the first round element and this free piece is then wound onto the second round element 25 under the effect of the weight of the paper storage surface 12.
  • the swivel lever is swiveled up, the paper storage area lowers and retains its horizontal position when swiveled, provided that the first and second round elements have the same diameter.
  • a tension lock 29 is arranged in the chain for presetting the height of the paper storage surface 12 and for adjustment.
  • a linkage that e.g. has the shape of a parallelogram and thus causes a permanent horizontal position of the paper storage surface when pivoting the swivel arm or correspondingly coupled gears.
  • position A, position B and position C denote various positions which can be taken up on the paper storage surface.
  • the paper depositing surface 12 can be moved into a removal position by entering a first removal position via the control panel 22 via the motor 20 B are brought.
  • the paper storage area is pivoted out of the printing device without the height of the paper storage area 12 having been changed.
  • the paper stack can easily be pushed from this position onto a corresponding lower transport device.
  • the paper storage surface 12 can be pivoted until it is swiveled in by entering the lifting height, for example in a digital manner via the control panels 22 or by simply permanently pressing a pushbutton via the motor 20 reaches a position C, in which the paper storage area is completely extended from the printing device and is at the same time at the desired removal height.
  • This position can, for example, also be stored in a memory of the control panels 22 for later pivoting processes and can be approached again and again will.
  • the paper storage area is returned to the starting position (operating position) by pressing a return key on the control panels 22 again.
  • the control device of the printing device and the motor 22 can be coupled in such a way that removal and thus pivoting out of the paper storage surface 12 is not possible during operation of the printing device, or that commissioning of the printing device is only released when the paper storage surface is swung in.
  • the swivel lever 16 is at the same time designed as a covering sheet for the compensating means of the paper storage area.
  • the pivot lever is guided in the region of the second free pivot point 18 from the axis of the second round element 25.
