Abstract

The invention in more detail explained solution of a vertical Baleabbindevorrichtung with automatic clamping, cutting and twisting device for binding wire represents a constructive new development. Thus, an increased automation of Ballenabbindevorganges is achieved in continuously operating high-performance balers. This improves the working conditions of the operator and increases the effectiveness through greater press performance resulting in time savings in Ballenabbindvoror. A special feature of this inventive solution is the easy interchangeability and use of various twisting tools for different binding wire strands. This is important in the production of different sized bales with different bale weight and specific pressing pressure for pressed material from different material types. The effectiveness increases in the time saved in the Abbindevorgang the larger and heavier the bales and thus a greater number of wire ties are required. But also in the production of small bales with low weight in the continuous pressing process, large quantities of light, voluminoese pressed material can be pressed in short times and tied with correspondingly thinner wire.

Description

For this 9 pages drawings

The invention relates to a vertical, mechanical Bailenabbindevorrichtung with automatic clamping, cutting and twisting device to the binding wire on horizontal channel balers with the highest pressing performance with continuous feeding loose, bulky pressed material, preferably paper and textile waste.

There are mechanical baling devices on hydraulic channel balers which belong to the respective baling systems and differ in their working and construction.

The invention has for its object to mechanize the Ballenabbindevorgang as much as possible. This improves the working conditions of the operators of the heavy duty baler press, and achieves greater press rates due to time savings in the baling operation. After the horizontal Bailenabbindevorrichtung according to WP 96 045 Although the binding wire was placed mechanically around the bale located in the compression channel under maximum pressure, but the cutting, clamping and connecting the wire ends still had to be done by hand.

The effectiveness of the novel solution according to the invention increases in the time saved, the larger and heavier the bales and thus a larger number of wire ties are required. The interchangeability of different twisting tools makes the use of multiple wire thicknesses possible. The invention will be explained in more detail using an exemplary embodiment.

in the accompanying drawings show:

Fig. 1: section through the main press (channel baler) when the Hauptpreßstempel is in the starting position. In front of the main punch (HPS) is a precompacted bale (B4) which was pressed in at right angles from the pre-press, horizontally into the main press channel. In the extension of the Hauptpreßkanales are the ready pressed and hardened bales - (B1 / B2 / B3). The binding wire for the bale (B4) is unwound from the bobbin under the press floor in a horizontal position, held vertically in guide rails between bales B4 and B3 from the closed clamping bar (Kg) in the upper end position of the binding device (A).

Fig. 2: The Hauptpreßstempel in the end position and the bale - (B4) is under maximum pressure. The pre-compressed bale (B4) shown in Fig. 1 was pressed by the Hauptpreßstempel with a stroke against the bale located in the bale finished (B1 / B2 / B3) under maximum pressure, they are thus moved by a bale length in the pressing direction and the whole Bailenabbindevorrichtung was pulled from the binding wire (Bz) by the same length in the pressing direction. Now the needles (N) move in overdrive from the upper to the lower end position.

Fig. 3: The needles (N) in the lower end position (uE). The horizontally tensioned binding wire (BD) is picked up by the pick rollers installed in the needles. The needles move in the Schneilgang in the upper Endsteilung (oE) and thus form an elongated, vertical binding wire loop, while the Abbindevorrichtung remains unchanged in the position shown in FIG.

Fig. 4: The needles (N) in the upper end position with the raised binding wire loop. Now, by pressing the button (T), see Fig. 9 - the clamping and cutting bar is opened and held open by the lock (SP). The binding wires thus exposed are pressed by hand from the vertical, in an almost horizontal position. - Now the binding device (A), which is easily movable in all directions, pulled by hand (Hz) against the pressing direction until it stops. - There, the binding wire loops are added in the upper end position (oE) of wedge-shaped openings of the clamping and cutting bar and immediately takes place automatically the cutting and clamping operation on the binding wire loop of FIG.

Fig. 5: The Abbindevorrichtung has reached the adjustable stop with the advanced mechanism on the cutting and clamping bar. In this case, the lock (SP) is released by spring pressure and the knife (M) in the tips of the wedge-shaped openings cut off the front part of the binding wire loop (S) by means of the spring pressure and the cutting wedge (SK), see the illustration in FIG. 9. The rear part of the binding wire loop is clamped immediately after the cut of the front part by fader pressure and held in the closed terminal block (Kg).

Fig. 6: The cut wire end is pulled by hand into an eye of the twisting tool (VDW) and bent over. With hand pull (Hz) the Bailenabbindevorrichtung is now pulled as far as possible in the pressing direction, while moving the twisting tools in the lower end position and engage there. The counterweight (G) is now in the upper end position.

Fig. 7: In this working position, the second end of the binding wire for the bale (B4) shown in FIG. 4 is suspended in the second eye of the twisting tool (VDW) and cut to the same length of the two wire ends. The binding wire ends held in the terminal block for the next bale (B5) hang loosely bent downwards, while the

Gear motor (GM - not shown in Figs. 1-6 and 8) is turned on by pressing a button on the control panel of the press and turns off when you release this button. Due to the even rotation of the twisting tools (VDW), the wire ends are connected around the bale, the binding tensioned and the catch released, which is intended for the lower end position of the twisting tools. The counterweight (G), with a slight overweight to Abbindevorrichtung (A), lifts the Verdrillwerkzeuge slightly upwards, so that the twisted wire ends are perpendicular to the bale surface, dam slip out of the loops or clamps of Verdrillwerkzeuge and by bale of the following pressing operations bent underneath the binding wire deflection wedges (BDUK) and thus applied to the bale surface.

Fig. 8: The mechanical baling process (B4) is completed. The counterweight (G) moves down and pulls the setting device (A) to the upper end position, so that the trapped binding wire for the next bale is held vertically in front of the needles (N). - The Hauptpreßstempel (HPS) moves by pressing a button on the control panel in overdrive back to the starting position. Now the next precompacted bale from the prepress can be pressed horizontally into the channel of the main press, in front of the main press die (HPS). Now repeat the operations as described for Fig. 1 to Fig. 9.

In the foreground (center and plan) the vertically and horizontally easily movable bale setting device. Drive of replaceable twist tools (VDW) with gears, in the middle a geared motor (GM). The opened cutting and clamping bar (Ko), lock (SP), knife (M), button (T), cutting wedge (SK) and binding wires (BD). - In the side elevation is shown above the cutting and clamping process with an open terminal block and bottom with the terminal strip closed.
