Pick-up press with plunger guided by rollers

The invention "relates to a pick-up baler for hay, Straw and the like, the plunger of which is attached to the baling channel by rollers on guide rails.

A piston knife is arranged along a vertical piston edge and rollers aa front side and the rear end of the lower edge of the piston on the longitudinal side of the piston on which the piston knife is arranged is provided.

Various roller-guided plungers are known, the rollers of which have horizontal and vertical axes. They run on webs or in longitudinal grooves of the baling channel. In order to safely guide the piston and to absorb the lateral forces that occur when a pack of goods is cut off by the piston knife, many rollers are required when using rollers with a flat running surface and horizontal and vertical axis, and their maintenance and readjustment are labor-intensive. It has therefore also been proposed to _let's just wheels with horizontal axis to use and perform their tread as Kreisringnut or trapezoidal Hingnut and they run in matching guide rails of the press channel. This should also absorb the side forces. These known designs, however, have the disadvantage that the pods with different diameters carry at the same time, that is to say lead at different circumferential speeds. EoLeroareh is one continuous Beibung between running surfaces and guide rails and thus high wear inevitably, dignity \ Hadius of the tread groove are executed large in these arrangements, however, than the Badius the Pührungs- I

If the piston did not seem to have a fixed side Leadership more.

Another disadvantage of all known AusJEÜhrunden be « This means that the piston © 2is must be fitted into the press channel by adjusting the rollers. Here the piston must be removed from the press channel taken out and the rollers in LangldOharn odar through © xssntrisehe Bolssnessführung vwatftllt w @ r-d «n. This work is time-consuming. Furthermore, the unavoidable welding failure in the press channel can be caused by the setting the rollers are not balanced "

The invention is based on the object of eliminating the disadvantages of the known designs described below and create a plunger guide su that requires as few balls as possible, which is easy to elniupaeisen and which is subject to the least possible wear *

This object is achieved in that rollers are also provided at the front and rear ends of the two piston edges on the longitudinal side of the piston opposite the piston knife, and that the rollers ( with their course are flat so directed towards the outside that

their axes of rotation with the adjacent piston lengths Include angles of around 4-5 °.

The rollers arranged in this way enable all forces to be absorbed. On the fourth long edge of the piston, namely on the upper side of the boiler, there are none Castors required · This edge must also necessarily be kept free of guide rails if beksaat * »Xeakeigestwa # rte front sink, so-called Baffer, used as a filling element from the feeder table into the baling channel.

They are another innovation claim Guide rails made of coil steel and the running surface of the rollers are designed as rings, with a radius The Hadius of the guide rails is slightly larger than that · As a result, one of the flat rollers occurs on the one hand approximate line contact on which the friction Avoid when asking questions at different radii at the same time. On the other hand, the lateral guide of the piston la Torbiriaung with the axes of rotation inclined by about 45 ~ of the rollers safely guaranteed

Furthermore, in such an embodiment, orphanage is a factor of pressed material on the guide rails avoided because small material parts are squeezed away to the sides by the clump while larger stalks are made by scraper plates, the are arranged on the piston face and the guide seemed to enclose almost halfway, stripped off will. The wiping takes place here cleaner than with the known wipers on flat guides, because there often the small good parts are rolled onto the flat running surface and then the roles on this Aufwalζ- • chicht run, which increases the gap between the scraper and the running surface, and new material deposits Π lukewarm * offers.

Due to the additional hardening of the rails, only slight wear occurs, so that an® readjustment occurs Wear and tear is not required

The guide rails on the opposite side of the channel from the Hesser are ix. horizontal and vertical direction infinitely adjustable. Set game. Uneven wear of the guide rails and welding jams can easily be compensated for.

The stepless © adjustment of the guide rails takes place by adjusting screws from the outside of the baling channel. It is easy to implement and takes little time

An exemplary embodiment of the invention is shown in the drawing shown. Ice is described in more detail below * Show it

1 shows a plunger and a sectioned baling channel in a perspective view,

Pig. 2 shows a section through these parts perpendicular to Piston central longitudinal saddle »,

3 shows an enlarged detail from FIG.

Fig. 4 is a view of the Xolben front side in detail.

The press channel 1 is designed as a welded construction. Its long edges were formed by the angle plates 2, 3, 4, 5 . The guide rails 6-8 are made of hardened hand steel. The guide rails 6 and 7 can be adjusted horizontally and vertically. * Five adjustment elements 9 are provided for each adjustment direction along the baling channel. Each adjustment element 9 consists of a pressing 10 and a pulling adjusting screw 11. The sectional drawing in Fig. 3 is laid out in such a way that the horizontal adjusting element is the tension screw and the vertical adjusting element is the pressure screw. The Zugsehxwibe 11 is screwed into a threaded hole in the guide rail 6 or 7

The guide rail 8 in the angle plate 5 is non-adjustable

The rollers 13 are mounted on bolts 15, their running surfaces 16 are designed as a circular groove, the radius of which is slightly larger than the hadius of the dog iron rails 6-8 the dog iron guide rails 6-8 almost halfway around. They can be adjusted and readjusted using elongated holes in their ■ screw connection.
