In a preferred embodiment of the invention, the rollers, rolls, etc. of the component units are attached to a frame, tunnel-shaped housing, etc., and the coupling members for adjacent component units, etc. are incorporated into the frame or housing. Thereby, the tunnel-shaped housing can be provided with a flange or the like on at least one side that can be connected to a flange of an adjacent component unit via a screw or bolt. Therefore, each component unit is constructed in such a way that its three free edges can be easily connected to an adjacent component unit having the same or different functions, such as twisting, direction change, etc., for example.

When the individual component units are assembled, the conveyor
In order to form a conveying device with an arbitrary length and an arbitrary height that does not require any further separate elements, a preferred embodiment includes a special component unit at the inlet and outlet of one paper product, respectively. and a conveyor belt pair drive motor is attached to one of the two special configuration units.

The twisting component is provided with particularly small rollers or rolls with narrow shaft spacing. It is also advantageous if the component for deflection is provided with at least one roller or roll having a much larger diameter than, for example, a roller or roll for guiding the product flow in a straight line.

Two rollers, rolls, etc. placed on one side of the product stream are combined in individual construction units to form a pair.

A frame supporting the rollers or rolls or the like includes a resiliently mounted roller or roll pair on one side of the product stream and a fixed roller or roll pair on the other side of the product stream.

In a preferred embodiment of the invention, tubes or rods etc., preferably of non-circular cross-section, are provided for connecting the component units, to which the individual component units, rollers and/or pairs of rollers are attached via clamping means and clamped. Each of the means consists of a flange and a bolt pair and surrounds the tube or rod in a yoke-like manner.

The means for twisting the product flow consist of a curved metal plate configured as a retaining plate with slots formed transversely to the direction of product flow for adjustably retaining the roller pairs.

The pairs of rollers or rolls are individually adjustable via rods or the like in arcuate, preferably quadrant-shaped slots in the retaining plate; perpendicular to the longitudinal axis of the retaining plate, the rollers or rolls are mounted at the free end. The holding plate is provided with brackets, etc., which are attached to both ends of the holding plate; the positions of the brackets attached to both ends of the holding plate are offset from each other by 90°; and the slots are arranged at equal intervals.

In a preferred embodiment, the means for diverting the product flow comprises a retaining plate on one side of which all roller pairs or roll pairs are mounted; slots for adjustably fixing the roller pairs or roll pairs are provided in the retaining plate. Provided with: pivotable roller pair support mechanisms on the inlet and outlet sides of the holding plate; each roller pair support mechanism for at least one roller pair or roll pair, an individual deflection roller and a return belt section; It consists of a direction changing roller.

Three deflection rollers are provided on the retaining plate for the endless auxiliary belt element and at least one as the outer belt element.
Embodiments with two deflection rollers are also possible.

Preferably, the conveyor belt pair engages one side of the paper product.

〔Example〕

Embodiments of the present invention will be described in detail below along with the accompanying drawings.

Since the conveying device of the present invention can be constructed by combining individual standardized structural units, each of which is provided with a joint member, height differences can be overcome. Product flow 9
A 0° or even 180' direction change is possible; it is also possible to twist the product flow. To achieve such a function, special structural units are provided depending on the required function; these structural units are combined according to the conditions of the installation site, and then the two belt elements are hooked and connected.

These structural units having a length of, for example, 1.0 to 1.5 m are detailed below in some embodiments.

A large roller 4 is attached to a frame 3 placed on pedestals 1 and 2, and two belts 5 and 6 are guided along this roller 4. A product stream fed in the direction of the arrow 7 and consisting of a scaly series of paper products first engages the conveyor belt 6 and is driven by the belt 6 into the space between the belts 6 and 5 and is clamped therebetween. That is, the belt 5 is connected to the large roller 4
The belt 6 runs along the circumference of the rollers 8, 9, and then both belts run parallel to each other in the conveying direction 7''.

Below the product flow, two rollers 16, 17 are each fixed to the frame via rods 18, 19.

The two conveyor belt sections running parallel are not shown.

In the embodiment of the structural unit for changing the direction of product flow shown in FIG. 3, a large roller 20 is provided on the frame 21,
The rollers 20 allow the product stream 7 to be deflected by 90° as shown.

The roller pairs 22 and 23 are fixed at various positions within the frame 21 as indicated by arrows 24 so that the angle of departure from the roller 20 can be adjusted in the range of 55° to 90''' or 20@ to 55'' depending on the frame. can do.

It goes without saying that the structural unit shown in FIG. 3 can be modified to allow direction change in any direction.

The structural unit embodiment shown in FIG. 4 is a tunnel-shaped housing 30.
It includes at least one pair of rollers 31, 32, after which the product stream is twisted by 90[deg.] by a group of small rollers, not shown.

A pair of rollers 33°3 is located downstream of the small roller group (not shown).

The component shown in FIG. 5 is a so-called ejector, in which at least one pair of rollers 41, 42 is provided in a housing or frame 40, and at least one of said rollers 41, 42 is operated, for example by an electric motor. It is driven by a drive unit. Regardless of the number of component units installed over the entire transport distance.

Even if there is only one pair of conveyor belts, a single drive means may be provided for the entire conveying device. Whether or not it is necessary to drive the rollers 41 synchronously, and if so, to what extent, depends on the conditions of use. That is, a synchronous circuit for driving a conveyor belt running along the circumferential surface of the roller 41 may be provided.

FIG. 6 shows an embodiment in which the product flow is conveyed upward and then transformed into a horizontal direction. In this embodiment, in addition to the large-sized direction-changing roller 50, a small-sized direction-changing roller 52 is installed inside the casing 51. establish. The support of both conveyor belts before they come into contact with the deflection roller 50 is provided by another roller 53.

On the outside of the casing 51, there are provided a pair of rollers 54.55 made of rollers of equal size and a pair of rollers 56.57 made of rollers of the same size.

FIG. 7 shows a component 60 for linear conveyance, which has a length of, for example, 1.5 m and is provided with a protective enclosure. The structural unit 60 includes five pairs of rollers each attached to a frame as shown in phantom lines, which frame is shown in side view in FIG. Frame 61 in Figure 9
is adapted to the contours of a protective enclosure or tunnel-shaped enclosure. The frame 61 is resiliently mounted within a housing 63 with links 62. which allow the rollers 64 to adapt to the thickness of the product stream as indicated by arrows 65. including.

The roller 66 is fixed to the frame via a fixed linkage 67.

FIG. 8 shows an enlarged view of this frame.

A housing 63 is attached to this frame exhibiting a quadrilateral shape,
A link 62 is elastically attached within the housing 63. The link supports a roller 64 having an annular groove 70 in the center. The roller 66 is fixed to the frame 61 via a connecting rod 71. The shafts of the rollers 66 project laterally and form support members 72, 73 which support the scaly stream 74 of paper products.

Each belt 5,6 has on its inside a continuous guide rib 75 which prevents the two conveyor belts 5,6 from shifting laterally.
．． 76'. The frame is provided with a protective enclosure 76 along the entire length of the component.

The protective enclosure is constructed so that it can support the frame without the need for additional supports. The protective enclosure 76 is provided with flanges 77, 78 which can be connected to corresponding flanges of adjacent components, for example via threaded bolts.

Instead of a protective enclosure, which is not absolutely necessary, the frames 61 may be connected to each other via linkages or plates, provided that in each case coupling means must be provided on at least one side of each component unit. ,
Said coupling means are a basic condition for employing individual component units that are manufactured in a factory and assembled at the installation site. As already mentioned, once the entire conveyor unit is assembled, the belts are hung and both belts are joined together;
FIG. 0 is a perspective view showing means for connecting the individual constituent units. This means is used in various lengths to connect the component units. This means is especially useful when guiding the product flow in a straight line.

It also serves as a support means for these rollers, whether they are individual rollers or pairs of rollers.

This means consists of a square cross-section tube 100, which can be fixed to the individual component or frame, chassis, etc., and yoke-like clamping means 101. The yoke-like clamping means consists of a rod 102 and two threaded bolts 103.
It consists of 104 pieces.

As is clear from FIG. 11, the roller pair 105 is pivotally attached to the retaining plate 106. Roller pair is bolt 10
The locking screw 108 connected to the angle iron is displaced and fixed in the 4-round slot 109 since it is held under the retaining plate via an L-shaped profile that pivots by 90'' about 7. be able to.

This adjustable pair of rollers is individually attached to a tube 100 or the like.

12 to 14 show an embodiment of the means for twisting the belt element 110, 111, a shell-shaped metal plate 112 curved over an angle of 180° and extending in a direction perpendicular to the plane of the drawing. Slots 113 for fitting each pair of rollers 114 are formed at equal intervals over the entire length of the roller. As will be described in detail later, this slot 113 is configured so that the individual roller pairs 114 can be fixed with their respective axial positions offset from each other.

A shell-like metal plate 112 is integrated into the conveyor system via a tube 100 and a yoke-like clamping means 101,
Each free end is provided with a bracket 120,121. The longitudinal axes of the brackets are orthogonal to each other. Each leg end of the bracket is fitted with a separate roller 122, 123 for redirecting the outer portion of the respective endless belt.

As already mentioned, only two endless belts are used in the entire conveying device, which are driven from one point, for example from the inlet end of the scaly stream of paper products.

In the embodiment shown in FIGS. 10 to 15, all roller pairs of the entire conveying device are provided on one side of the device, and only the edges receive the stream of paper products in the form of scales, so that the paper products or Part of the product flow protrudes to the side. The black stream is guided to the outlet by two adjacent parts of the inner and outer belt elements, except for a so-called curve mechanism which will be described below. The return parts of the two belt elements are guided linearly or deflected by spaced roller pairs and partly by individual rollers.

As is clear from FIG. 13, the shell-shaped metal plate 112 is formed in a direction perpendicular to the longitudinal axis of the plate.

As already mentioned, over the entire length of the metal plate, including a number of curved slots into which a pair of roller pair holders 130 are inserted, for example the axes of the roller pairs at the product flow inlet are perpendicular to each other with the axes of the roller pairs at the outlet. The positions of the roller pairs can be staggered with respect to each other so as to form.

FIG. 14 shows on a reduced scale an embodiment in which a pair of rollers 114 whose rotating shafts are parallel to the plane of the drawing is provided at the inlet end of one belt section 110, 111 of vertically arranged metal plates. Also attached to the bracket 120 is an individual roller 123 whose axis is approximately parallel to the axis of the roller pair 114.

This roller causes the return belt section 131 to change direction.

The other end of the bracket 120 is also fitted with a separate roller whose axes are also parallel or nearly parallel to the axes of the roller pair 114 to deflect the return portion of the belt element 132. A pair of rollers 113 is provided at the lower end of the scrap metal plate 112, the rotation axis of which is perpendicular to the plane of the drawing. Similarly, the individual rollers 122, 134 are attached to a shaft whose axis of rotation is approximately parallel to the axis of rotation of the roller pair 113.

It goes without saying that since the individual roller pairs can be fixed in any longitudinal position in the slot, the belt element pairs can also be guided linearly or approximately linearly in the area of the metal plate.

The curve mechanism shown in FIG. 15, namely both belt portions 110
, 111 comprises a holding plate 140 and a pivotable plate 141 or 142 attached thereto. A square cross-section tube 100 is fixed on the underside of the retaining plate 140 with yoke-like clamping means 101, so that the curve mechanism is integrated into the conveyor system together with said coupling means.

The retaining plate 140 includes slots 142 of different lengths and individual rollers 143 for upward adjustment in the plane of the drawing.
are installed within these slots.

Therefore, the retaining plate 140 can not only redirect the product flow consisting of a scale-like paper product by 90 degrees as shown, but also can redirect the product flow by an angle greater than that. The plates 141, 142 are pivotable and are therefore provided with arcuate slots 150, 151 of length that limit the range of their pivoting.
and 152 are formed. When fixing the pivot plates 141, 142 in the slots, their positional relationship can be chosen in an infinite number of ways.

Since the inner belt element 110 in the curve mechanism is slightly shorter than the outer belt element 111 in the curve mechanism, it must be ensured that no deviations in product flow occur; for this reason, the outer belt element 111 from the roller pair 155 is first rotated in the direction. After being introduced into the converting roller l°56, it is again guided to the roller pair 15'7.

The outer belt element 111 is a direction changing roller 160.161
After passing through 162 and 163, the process moves to the return stroke.

The inner belt element 110 is a direction changing roller 170.171
Then, the process moves to the return process via 172.

In order to keep the product flow in place even in the area of the curve mechanism, an auxiliary belt element, a so-called rider belt 180, is provided, which is connected to three direction changing rollers 1g1.
