Description

The invention relates to a device for transporting flat, flexible objects along a transport path.

Are known devices for the transport of flat, flexible objects along a transport path, for example, in feeders for printers, especially large format printers, or other processing equipment. Such devices should be for flat, flexible objects made of different materials, such as paper, cardboard, cardboard, plastic, metal or other, be used, the objects in particular have different thickness and have different material properties. In order to ensure a high feeding accuracy, which is required for printing, among other things, the supplied objects are aligned on at least one side of the feeder by means of a guide member laterally on the transport path. The known guide elements have two side surfaces arranged at an angle to one another.

In this case, rectangular guide elements are known, which are aligned with the transport path such that one side surface is arranged parallel below the object and the other side surface at right angles to the plane of the object. The objects are thus guided along the one side surface and in particular applied and aligned thereto. The problem is, however, that especially with thin materials, such as thin paper, the outer edge of the object on the outer side of the guide member is pulled up and the object is then no longer aligned in a right angle.

In order to avoid the high-level migration occurring on the outer surface of the guide element in thin objects, it is known to form the guide element with an angle which is smaller than 90 degrees and to guide the medium at the acute angle laterally, wherein one of the side surfaces of the guide element Object overlaps and one of the side surfaces of the guide element engages under the object. In such a guide member, however, there is a problem that objects of greater thickness can jam within such a guide member.

The object of the invention is therefore to develop a device for transporting flat, flexible objects along a transport path in such a way that it can be used for different objects, in particular objects of different thicknesses.

The object is achieved by a device for transporting flat, flexible objects along a transport path with features of claim 1.

Advantageous embodiments and further developments of the invention are specified in the dependent claims.

The device according to the invention for transporting flat, flexible objects along a transport path with a transport path and at least one laterally arranged on the transport path guide element with two mutually arranged at an angle side surfaces is characterized in that the guide element is arranged pivotable relative to the transport path about an axis , This makes it possible to adapt the orientation of the guide element relative to the transport path as a function of the flat, flexible objects to be transported, in particular as a function of the thickness and / or the material structure of the objects in order to optimally adapt the device to the corresponding objects to be transported.

According to a particularly preferred refinement, in a first position of the guide element, one of the side surfaces is arranged approximately perpendicular to the plane of the flat, flexible object to be transported and protrudes into the space above the flat, flexible object in a second position of the guide element. The orientation of the side surface in the first position approximately perpendicular to the plane of the flat, flexible object to be transported allows a lateral stop especially for thicker, flat, flexible objects, without the risk of jamming of the objects on the guide element, while the orientation of the side surface in such a way in that it projects into the space above the flat, flexible object, allows lateral guidance, but prevents thinner, flat, flexible objects from traveling up the side guide.

Preferably, the axis is arranged substantially parallel to the transport path. Particularly preferably, the axis runs parallel to the line of intersection of the two side surfaces of the guide element.

A particularly preferred embodiment of the invention provides that the axis is arranged below the transport path, which allows a compact and space-saving arrangement.

Particularly preferably, the axis is in an area on a free side edge of one of Side surfaces of the guide element arranged, which allows a particularly space-saving arrangement.

A particularly preferred embodiment of the invention provides that the angle of the mutually arranged side surfaces is smaller than 90 °. Such a guide element can be arranged particularly space-saving pivotable laterally on the transport path. The angle of the mutually facing side surfaces is preferably between 30 ° and 85 °, more preferably between 60 ° and 80 °, for example about 70 °.

According to an advantageous development of the invention, the transport path has at least one transport belt, which enables a reliable transport of flat, flexible objects.

Particularly preferably, the transport path has at least one suction and transport device with first means for generating a negative pressure by means of a whirlwind for sucking at least one object, wherein the first means are arranged within a housing which has a suction opening. Such suction and transport devices are particularly effective, small and inexpensive.

The 1 to 8th show different views of an embodiment of a device according to the invention 10 for transporting flat, flexible objects 50 . 52 along a transport path 12 , For a better overview, not all reference numbers are given in all figures. The objects 50 . 52 differ essentially in their thickness, which is the object 50 around a thicker and at the object 52 is a thinner object.

The device 10 is designed to be objects 50 . 52 along the transport path 12 to move, including along the transport path 12 several suction and transport devices 16 are arranged. The suction and transport devices 16 preferably have first means for generating a negative pressure by means of a whirlwind for sucking the object 50 . 52 on, wherein the first means are arranged within a housing, which has a suction opening. The suction and transport devices 16 advantageously have at least one, for example two conveyor belts 14 on, by means of which the object 50 . 52 when circulating the transport belt 14 in the direction along the transport path 12 is moved on. In this case, the means for generating a negative pressure by means of a whirlwind, the plant of the object 50 . 52 on the conveyor belt 14 for sure.

Side of the transport path 12 is at least a guide element 20 arranged, which two at an angle α mutually arranged side surfaces 21 . 22 having.

The angle α may be about 90 °, but is preferably less than 90 °, is preferably between 30 ° and 85 °, more preferably between 60 ° and 80 ° and may for example be about 70 °.

The guide element 20 is about an axis 30 relative to the transport path 12 pivotally arranged, in particular between a first position and a second position. In the first position of the guide element 20 is the side surface 21 approximately perpendicular to the plane of the flat, flexible object to be transported 50 . 52 arranged (cf. 2 ). In the second position of the guide element 20 protrudes the side surface 21 in the above the flat, flexible object 50 . 52 laying room (cf. 4 ).

In the first position, therefore, the object 50 be guided laterally. The thickness of the object 50 can vary as you like. For thicker objects 50 These have sufficient rigidity, not to the side surface 21 high immigrate. Because of the side surface 21 substantially perpendicular to the plane of the flat, flexible object 50 runs, there is no danger of jamming of the object 50 ,

In the second position of the guide element 21 grips the side edge of the object 52 in the area between the two side surfaces 21 . 22 of the guide element 20 one and the side surface 21 Thus, in particular, it overlaps the flat, flexible object 52 , This causes a high-altitude walk on the side surface 21 which is especially suitable for thin, flat, flexible objects 52 can occur, avoided. For thin objects 52 however, although that is the object 52 in the acute angle α between the two side surfaces 21 . 22 engages, no danger of jamming.

The axis 30 to which the guide element 20 is arranged pivotably, in particular runs substantially parallel to the transport path 12 , The axis 30 can parallel to a cutting line 25 between the side surfaces 21 . 22 of the guide element 20 run and in particular on a free side edge 22a the side surface 22 be arranged. To enable a compact construction, the axis is 30 especially below the transport path 12 and in particular below the object to be transported 50 . 52 arranged. In this case, a pivoting device 40 be provided, which is the guide element 20 around the axis 30 pivoted between the first and the second position.

As in particular in 5 can be seen, the direction of the transport belt 14 against the direction of the transport path 12 at an angle β in the plane of the transport path 12 , what a 5 runs parallel to the paper plane, be arranged inclined. In particular, such an incline provides an improved investment along the transport path 12 occupied object 50 . 52 on the guide element 20 for sure.
