Definitions

• the invention relates to a device for producing wrapped press bales in which there is compressible material, with a vertically movable pressing device which is equipped with at least one rotatable, conical compacting roller, with a receiving device designed as an open cylindrical hollow body for receiving the material to be pressed Good and with a bottom plate closing the receiving device downwards and detachably arranged by the receiving device for supporting the pressed bales.
• this device can only be used to press goods or materials that, due to their structure, do not fall apart again after the pressing process.
• Garbage is a typical example.
• you wanted to press bulk goods or, for example, finely chopped plant goods you would quickly come up against limits, because at least at the latest when transporting such pressed bales Detach portions of the pressed goods from the pressed bales or even break them apart again.
• the task of the invention is to further develop a device of the generic type in such a way that it is suitable for pressing a wide variety of goods.
• the device to be created should be adjustable with a view to optimizing the pressing process for the goods to be pressed.
• the device is intended to allow wrapping of the press bales with film without the production process of the press bales being delayed.
• the solution to the problem is that the receiving device and the base plate are rotatably mounted about a common vertical axis, that the base plate is additionally movable in the vertical direction and that a winding device equipped with at least one winding head is arranged in such a way that at the beginning of the Winding process, the at least one winding head is located at the level of the common connection area between the receiving device and the base plate.
• the main advantage of the invention is that the operation of the proposed device can be adjusted to the physical properties of the material to be pressed. This can be achieved in particular by the fact that the receiving device, the base plate and the compressor rollers can be rotated independently of one another. As a result, different operating states can be set up with the possibility of finding and using the most optimal pressing process for a certain good. In the case of bulky goods, such as those found in garbage, the pick-up device and the base plate will be made to rotate more slowly than with chopped plant material. The fact that this material can be fed to the receiving device more uniformly means that the receiving device and the base plate can be rotated more quickly.
• the receiving device and the base plate do not necessarily have to move synchronously, in fact the receiving device can even stand still if it serves to optimize a pressing process. mieren. Even the rotary movements of the compressor rollers can be selected differently. It has also proven to be advantageous that the pressed bale can be pressed downwards out of the receiving device, the winding device being activated at the same time and the pressed bale being gradually wrapped in film by the winding head. It also proves to be expedient to keep the winding head ready at the level at which the wrapping of the bale can be started as soon as the pressing process is complete. This means that no valuable time is lost in the manufacturing process.
• the invention permits further advantageous configurations. It is thus possible, in addition to the variation options just mentioned, to select the pressing forces of the pressing device at different levels.
• the pressing forces will be kept low, particularly in the case of sensitive goods, for example those intended for animal feed. Nevertheless, it is possible to work with high press forces if the material to be pressed, such as garbage, also allows such high forces. Then press bales can be produced which have a very high density and thus take up the same quantity units of the material to be pressed, correspondingly less space.
• each compression roller with its outer frontal boundary can be moved almost to the inner wall of the receiving device. It proves to be useful if, for example, when using at least two compression rollers, one of the rollers is longer than the other compression roller and the longer roller, viewed from above, extends beyond the vertical axis of the receiving device. In this way, when the base plate is rotating, there is no unpressed area left in the center of the press bale.
• the press device also to arrange another scraper, which extends in the vertical direction and serves to scrape the inner wall of the receiving device and thus to keep it clean.
• FIG. 1 shows a device at the start of the filling and pressing process
• FIG. 2 shows the same device with a press bale located on the lowered base plate.
• the device 1 intended for the production of wrapped press bales 33 has a stationary support frame 7.
• the support frame 7 is equipped with lower guides 8a, which run vertically and in which a support device 2 is guided in a vertically movable manner.
• the support device 2 carries a base plate 3 which, driven by a motor 45, can be rotated about a vertical axis 5.
• Above the base plate 3 there is a receiving device 9 for receiving material 31 to be pressed, for example bulk material, vegetable material or also garbage.
• the receiving device 9 is cylindrical. It is arranged rotatably on the support frame 7 and, like the base plate 3, can be rotated about the vertical axis 5.
• a friction wheel 41 driven by a motor is provided, for example, which is pressed against the outer jacket 15 of the receiving device 9.
• the receiving device 9 is like an upright pipe with a large diameter.
• Opposite upper guides 8 are arranged on the support frame 7, in which a pressing device 18 is guided in a vertically movable manner.
• the pressing device 18 leads with two strong arms 19 from top to bottom into the receiving device 9.
• At the lower end of each arm 19 a conical or conical compacting roller 20 is provided, the respective longitudinal axes 23 of which are arranged inclined to a horizontal.
• the compressor rollers 20 are designed such that the diameter of their outer end face 21 is larger than the outer diameter of their inner end face 22.
• the position of the longitudinal axes 23 of the compressor rollers 20 is so chosen that their treads 24 can rest snugly on the horizontal plane 4 of the underlying base plate 3, as is also clear from the drawing.
• the drawing also shows that the arrangement of the compressor rollers 20, which in the example is mounted on the fly, makes it possible to approach the cylindrical inner wall 11 of the receiving device 9 with the outer end face 21 of each compressor roller 20.
• a scraper 30 is arranged in a stationary manner on the pressing device 18 in order to enable an approximately uniform supply of the material 31 to be pressed to the compressor rollers 20.
• a further scraper 30a can optionally be provided, which is arranged vertically on the pressing device 18 and serves to scrape off the inner wall 11 of the receiving device 9 and to keep it free of material 31 to be pressed.
• a feed arrangement 29 leads from above to the receiving device 9 and to the pressing device 18, through which the material 31 to be pressed is guided to the receiving device 9.
• a winding device 37 equipped with at least one winding button 37a, which is intended for wrapping a press bale 33, for example with film 38.
• the winding heads 37a which are each rotatably mounted about a vertical axis, can also be mounted on a circular path and can also be rotatably guided about the vertical axis 5.
• the cylindrical base plate 3 is frustoconical in shape and tapers upwards.
• the lower region 12 of the receiving device 9 is of opposite conical design.
• a correspondingly designed ring 13 is provided for this purpose at the lower end of the receiving device 9 on its outer jacket 15.

• the lower edge 16 of the receiving device 9 either rests on the base plate 3, or an annular gap with a height of a few millimeters is formed between the base plate 3 and the lower edge 16 of the receiving means 9 in order, for example, to allow liquid settling out during the pressing process .
• the compressor rollers 20 are arranged at a short distance from the horizontal plane 4 of the base plate 3. Both the receiving device 9 and the base plate 3 are set in preferably synchronous rotary movements with the aid of their drive devices.
