Definitions

  • the present invention relates to a press head, a device for pressing material and a method for pressing material according to the preambles of the independent claims.
  • waste materials in the form of shavings are produced. Depending on the material being machined, these shavings represent an important link in the value chain. On the one hand, raw materials should not be wasted; on the other hand, the raw materials, and in this case the shavings, should or can be reused.
  • DE1627914 The figure shows a press head with a press channel and a press element movably arranged within the press channel.
  • the movable press element exerts a force on the material to be pressed, which can be adjusted using a screw spindle.
  • the device from the DE1627914 proves unsuitable for pressing materials with high inhomogeneity. exhibits the characteristics present in wood chips. Clover or grass chips, for which the press head according to DE1627914 Chips that are designed for this purpose are uniformly chopped and exhibit a homogeneous size distribution. Pressed material, which is produced, for example, during the mechanical processing of workpieces, exhibits a high degree of inhomogeneity. This is due, for example, to machining the workpiece with different tools. Thus, very large as well as very small chips can be produced simultaneously.
  • the press head from the DE1627914 It is equipped with a spring that exerts a constant static preload force on the pressing element. This preload force can be preset using an adjusting screw, but then remains unchanged. Another disadvantage of this known device concerns the limited amount of material that can be processed or pressed per stroke.
  • DE260831C Disclosing a press head for a device for pressing material according to the preamble of claim 1, in particular a briquette extrusion press for briquetting lignite or peat. It has a pressure piece for distributing the pressure.
  • the purpose of the invention is to eliminate these and other disadvantages of the prior art.
  • a press head according to the invention for a device for pressing material and in particular for pressing chips, preferably an extrusion press, comprises the features of claim 1.
  • the press head has a die positioned in front of the entry opening of the press channel.
  • the entry opening of the press channel then coincides with an entry opening of the die. That is, the press channel encompasses the die or its opening.
  • the die has one opening for each press channel.
  • the change in the cross-section of the press channel at its outlet relative to the cross-section at its inlet allows for a more or less pronounced clamping of a briquette within the press channel. While the briquette naturally has a cross-section during the pressing process that essentially corresponds to the cross-section of the press channel at its inlet, the inhomogeneity of the material being pressed into a briquette means that the briquette's cross-section is more or less elastic; that is, individual briquettes exhibit different degrees of elasticity.
  • the cross-section of the press channels is essentially constant. This ensures that a second briquette, subsequently pressed in the press channel, encounters sufficient resistance from the first briquette. This improves the quality of the subsequent briquette.
  • the cross-section of the press channels is individually adjustable for each channel. The quality of the briquettes remains essentially constant and at a high level, regardless of the nature of the material being pressed.
  • the press channels are formed in their cross-section essentially half by the support element and half by the press element. It is conceivable that a gap forms between the support element and the press element, which need not be completely closed even if the cross-section at the outlet opening is reduced.
  • the press element only corresponds approximately to the diameter of the press channel and is designed as an insertion element on the press head, which completes the cross-section of the press channel.
  • the press channel has a longitudinal axis between its inlet and outlet openings and is open along this axis at a right angle to it. This means that the inlet and outlet openings are connected by an open channel.
  • the press element can be located within this open channel and is, in particular, movably arranged within it.
  • the press channels have a common support element.
  • This support element is preferably one-piece, in particular formed in one piece.
  • the common support element also positions the press channels relative to each other in a fixed position.
  • each press channel has a separate pressing element, uneven wear of the parts or areas of the respective press channels located in the support element is not a problem.
  • the holding force can be adjusted independently for each press channel.
  • the press channels can be arranged side by side in the press head.
  • the press channels are arranged opposite each other. This means that the press channels lie in a common plane, have a common pressing direction, but the pressing elements are arranged opposite each other or diametrically.
  • press channels lie in a first plane, and the press elements in a second plane parallel to it.
  • the support element would, in principle, be in a force-neutral position. While such an ideal force distribution naturally does not occur in practice, the forces on the support element can at least be reduced when the press elements are actuated simultaneously.
  • the press head is designed such that each pressing element is pivotably mounted about a rotational axis, preferably fixed relative to the support element.
  • This axis is located, in particular, in the area of the inlet opening of the press channel.
  • the rotational axis is arranged essentially perpendicular to the press channel. That is, the rotational axis lies in a plane parallel to a plane through the longitudinal axis of the press channel and has a direction perpendicular to the longitudinal axis of the press channel. In the case of multiple press channels, the plane is defined by the multiple longitudinal axes of the respective press channels.
  • each pressing element is assigned an adjusting element for adjusting the pressing element. This enables the pressing or holding force to be adjusted at each pressing element.
  • each actuating element is independently adjustable and, in particular, can be controlled independently.
  • the pressing force in each press channel can therefore be adjusted independently. This allows for control over the briquette during the pressing process.
  • the actuating elements can be designed, for example, as hydraulic or pneumatic components.
  • a spring can also be used. Electrical or mechanical actuating elements are also conceivable.
  • three press channels are arranged side by side.
  • more than three press channels side by side are also conceivable.
  • This can be advantageous, for example, if the material to be pressed is known during the design phase and has a specific distribution or size, or is a mixture of materials, such as large and small chips. If, for instance, the press channels are arranged opposite each other in the direction the material falls, it can be assumed that smaller chips will collect in a lower section of the device and larger chips in an upper section. In this case, it can be advantageous to have, for example, two press channels in the lower section and three in the upper section. This allows the desired compression to be achieved.
  • Another aspect of the invention therefore also relates to a device for pressing material, in particular for pressing chips and in particular an extrusion press, wherein the device for pressing material comprises at least one press head as described above.
  • the device comprises a press head as described herein, wherein each press element is assigned an adjusting element for adjusting the press element.
  • the device includes a control device for adjusting the adjusting element.
  • each press channel is assigned a press piston for pressing the material being pressed.
  • the press pistons can be moved by means of a common cylinder.
  • the device as described herein may have a pre-collection chamber for receiving and/or pre-compacting the material to be pressed.
  • the pre-collection chamber is preferably assigned to all pressing channels simultaneously.
  • a device for pressing material has a filling device, which is typically designed as a funnel.
  • the material to be pressed is collected in the hopper and guided to the press head. The material may then be transported to the press head solely by gravity. The material to be pressed is conveyed. Alternatively or additionally, other elements are conceivable that convey the material, such as screw conveyors or the like. Typically, at least one mechanical conveying element is located within the hopper in connection with the press head, which ensures that there is always enough material available for pressing.
  • such a screw conveyor leads into a pre-collection chamber that receives the material to be pressed before pressing.
  • the forced conveying action of the screw conveyor can result in a pre-compaction of the material.
  • the material is pressed from the pre-collection chamber into briquettes and collected for further processing, for example in a trough.
  • the device can be designed as an integral component of another machine, such as a machining center. A separate version is also conceivable. In this case, the device can include additional elements for setup, such as a machine frame.
  • Another aspect of the invention relates to a method for pressing material, in particular with a device as described herein and preferably with a press head as described herein.
  • the method comprises the steps listed in claim 14.
  • the pressing force on the second portion of the material being pressed is adjusted by the movable pressing element, in particular by a holding force of the first portion of the material being pressed in the pressing channel.
  • the material to be pressed is pressed simultaneously through two or more pressing channels.
  • the starting position corresponds to the position of the press piston in its retracted state, when the press piston releases the pre-collection chamber or is in its position furthest possible from the inlet opening of the press channel.
  • the final position of the press piston can be defined, on the one hand, by when a certain distance has been traveled, which is determined, for example, by a measurement on the cylinder or press piston. It would also be conceivable to link the final position to reaching a specific force.
  • the process can then be repeated, with the portion that was previously second becoming the first.
  • this equilibrium between the first and second portions is only established after several iterations of the process.
  • the first few of these cycles can therefore be described as the start-up phase, until a stable state is reached.
  • This process makes it possible to achieve a correspondingly equivalent quality of briquettes for each press channel when several press channels are arranged next to or above each other.
  • an adjusting element for setting the holding force as a function of an adjusting variable on the press cylinder or on the press piston is set independently for each press element.
  • control variable is defined as a function of the force applied to the press piston.
  • the force applied to the press piston is a direct indicator of the briquette's properties and allows for a clear statement about the pressing process.
  • force measuring strips or similar devices can be attached to the piston, providing a value for defining the manipulated variable.
  • the press pistons are hydraulically operated.
  • the actuating variable can be defined as a function of the hydraulic pressure.
