Extrusion device and base frame Description

[0001] The invention relates to an extrusion device comprising at least one screw extruder for processing material, in particular plastic material, and at least one metering frame for a metering device. Furthermore, the invention relates to a base frame on which at least one screw extruder can be mounted.

[0002] Extrusion devices often have one or more metering devices that serve to feed and / or meter the material to be processed or the additives to be added into the screw extruder. The metering devices are typically arranged in an area above the screw extruder. Various designs are known. For example, metering devices can be mounted vertically above the cylinder housing of the screw extruder. Furthermore, metering devices can be mounted on a support arm that is attached vertically above the screw extruder to the building ceiling or to a three-dimensional structure. Such arrangements are known, for example, from DE 10 2004 040 185 A1 and DE 20 2007 014 877 U1.

[0003] A disadvantage is that such arrangements require more space to even provide the supporting structures. Furthermore, the existing arrangements do not provide good access to the screw conveyor. The large drop heights between the dosing unit and the screw conveyor also have a negative impact.

[0004] The invention is based on the object of structurally and / or functionally improving an extrusion device mentioned above. Furthermore, the invention is based on the object of structurally and / or functionally improving a base frame or dosing frame mentioned above.

[0005] For example, it is an object of the present invention to provide an extrusion device and a base frame with a dosing frame, which can reduce or eliminate the problems identified in connection with the prior art. In particular, it is an object of the present invention to significantly reduce the space requirement and / or the drop height. Nevertheless, good accessibility to the components of the screw extruder, for example, from above, should be enabled.

[0006] The problem is solved by an extrusion device having the features of claim 1. Furthermore, the problem is solved by a base frame having the features of claim 13. Advantageous embodiments and / or further developments are the subject of the dependent claims, the description, and / or the accompanying figures.

[0017] In one variant, two dosing racks can be provided. The two dosing racks can be mounted on opposite sides of the base frame. For example, a first dosing rack can be mounted on the left side of the base frame, as viewed in the longitudinal direction of the base frame and / or the longitudinal direction of the screw extruder, and a second dosing rack can be mounted on the right side of the base frame, as viewed in the longitudinal direction of the base frame and / or the longitudinal direction of the screw extruder. The two dosing racks can be essentially identical.

[0018] The at least one dosing frame can be movable in the longitudinal or transverse direction of the at least one screw extruder and / or in the longitudinal direction of the base frame. For this purpose, at least one single-axis or multi-axis linear guide can be provided. By means of the linear guide, the at least one dosing frame can be arranged on the base frame and / or can be moved, for example, linearly. The linear guide therefore also allows the at least one dosing device to be moved linearly. For example, the at least one dosing frame can be mounted on the base frame via the at least one linear guide. The at least one dosing frame and / or the dosing device can be positioned and / or moved manually, semi-automatically, or automatically. The at least one linear guide can be designed for manual, semi-automatic, or automatic movement of the dosing frame and / or the dosing device, for example electrically, pneumatically, or hydraulically.The linear guide can have at least one rail, e.g. a running rail and / or guide rail. For example, two rails can be provided which are spaced apart from one another, in particular vertically. Furthermore, the linear guide can have at least one axis, e.g. a running axis and / or linear axis. The at least one axis can be coupled to the at least one rail such that the axis can be moved along and / or substantially within the rail.

A control system can be provided for the linear guide and / or its axes and / or its sliders, which control system is configured to initiate or carry out an actuation of the linear guide and / or its axes and / or the at least one slider. This can result in a linear movement of the dosing frame and / or the dosing device. Furthermore, the linear guide can have at least one actuator. The at least one actuator can be attached, e.g. fastened, to the base frame or to the dosing frame. The at least one actuator can enable a linear movement and / or be designed to carry out a linear movement. This can result in a linear movement between the dosing frame and the base frame, or a linear movement of the dosing frame and / or the dosing device relative to the base frame.The actuator can be a linear actuator, for example, an electric, pneumatic, or hydraulic linear actuator. The actuator can comprise a cylinder-piston arrangement, a spindle arrangement, or a spindle drive. Additionally or alternatively, the linear guide can have a handle for manual movement, e.g., by an operator. The handle can be attached to the dosing frame.

[0019] The at least one dosing frame can have an adjusting device for positioning the Dosing device relative to at least one screw machine and / or relative to the base frame. For example, the adjusting device can be designed to pivot and / or adjust a height of the dosing device, in particular relative to the at least one screw machine and / or relative to the base frame.

[0020] The adjusting device can have a pivoting mechanism. By means of the pivoting mechanism, the dosing device can be pivoted or rotated about a vertical axis of rotation, for example into a dosing position and / or cleaning position. The pivoting mechanism can be designed to be manually, semi-automatically, or automatically actuated, for example electrically, pneumatically, or hydraulically. Furthermore, the pivoting mechanism can have a pivoting or rotational axis about which pivoting or rotation is possible. The pivoting or rotational axis can be the vertical axis of rotation. A controller can be provided for the pivoting mechanism, which is designed to initiate or carry out pivoting or rotation. Furthermore, the pivoting mechanism can have at least one actuator that enables a pivoting or rotational movement and / or is designed to carry out a pivoting or rotational movement.The actuator may be a pivoting or rotary actuator, for example, an electric, pneumatic, or hydraulic pivoting or rotary actuator. The actuator may comprise a drive, for example, an electric motor, a stepper motor, or a spindle drive. Additionally or alternatively, the actuator may have a rotary element, e.g., a rotary disk, and an actuating rod coupled thereto. The actuator may further comprise a cylinder-piston arrangement or a spindle arrangement configured to effect movement of the actuating rod. Additionally or alternatively, the pivoting mechanism may have a handle for manual pivoting or rotation, e.g., by an operator.

[0021] Furthermore, the adjusting device can have a leveling mechanism for leveling the dosing device. The leveling mechanism can comprise adjustable screw connections. The screw connections can each have two nuts and a threaded rod, which are arranged, for example, in such a way that leveling or raising and / or lowering can be carried out. The leveling mechanism can be designed to be manually, semi-automatically or automatically actuated, for example electrically, pneumatically or hydraulically. Furthermore, the leveling mechanism can have one or more axes, e.g. lifting axes, along which raising and / or lowering is possible. A controller can be provided for the leveling mechanism which is designed to initiate or carry out leveling and / or height compensation or raising and / or lowering. Furthermore, the leveling mechanism can have at least one actuator which enables raising and / or lowering and / or is designed to carry out a lifting movement. The actuator can be a lifting actuator and / or linear actuator, for example an electric, pneumatic or hydraulic actuator. The actuator can comprise a drive, for example an electric motor, stepper motor or spindle drive.The actuator can further comprise a cylinder-piston arrangement or a spindle arrangement which is designed to effect a lifting movement and / or raising and / or lowering. Additionally or alternatively, the leveling mechanism can have a handle for manual raising and / or lowering, e.g. by an operator. The at least one dosing frame can have a support plate. The dosing device can be or is attachable to the support plate. The support plate can be pivotable, rotatable and / or levelable, e.g. by means of the adjusting device. The support plate can be pivotable or rotatable about the vertical axis of rotation by means of the pivoting mechanism and / or levelable by means of the leveling mechanism. Leveling can also be understood as height compensation and / or raising and / or lowering.The leveling mechanism can be used and / or designed to compensate for the height and / or to raise and / or lower the support plate and / or the dosing device. The support plate can furthermore have at least one recess, for example two, three, four or more recesses. The at least one recess can be designed to position the support plate, in particular in a plane running essentially in the horizontal. For example, the at least one recess can be designed as an opening and / or hole, such as an elongated hole. The support plate can be moved through the at least one recess, in particular in the plane running essentially in the. The support plate can be designed to be movable in a horizontal plane. This also allows a dosing device arranged on the support plate to be positioned and / or moved in a plane that runs essentially horizontally.

[0022] A further aspect relates to a base frame on which at least one screw extruder can be mounted. The base frame can be a machine base frame. At least one dosing frame for positioning a dosing device relative to the base frame and / or relative to the at least one screw extruder can be mounted and / or fastened to the base frame. The base frame and / or the at least one screw extruder and / or the at least one dosing frame and / or the dosing device can be designed as described above and / or below. For example, the at least one dosing frame can be mounted and / or fastened laterally to the base frame. Furthermore, the at least one dosing frame can be movable in the longitudinal direction of the base frame and / or in the longitudinal direction of the at least one screw extruder, for example by means of the linear guide.In one variant, the at least one dosing frame can be designed to pivot and / or level the dosing device, for example by means of the adjusting device described above and / or below.

[0023] In summary and to put it another way, the invention thus results in, among other things, a base frame with a dosing frame mounted thereon for a dosing device, such as a dosing unit. The dosing frame is universally applicable and can be mounted directly onto the base frame for a screw machine. The drop height between the dosing device, for example the conveyor screw of the dosing device, and the screw shafts of the screw machine can therefore be reduced. By mounting two identical dosing frames laterally, e.g. left and right, on the base frame, such as the machine base frame, installation space can be saved. By providing linear guides, universal usability and / or positioning can be enabled. For example, the dosing device can be positioned at the inlet hopper of the screw machine or at the inlet hopper of a side-feeding screw machine, simply by sliding and / or pivoting.Furthermore, height compensation and / or leveling of the dosage can be provided, for example via a. separate plate. The dosing device and / or plate can also be pivotally mounted on the dosing frame, for example, in such a way that it can be pivoted away.

[0024] The invention significantly reduces the installation space requirement. Access to the screw extruder can also be improved. The drop height between the dosing unit and the screw extruder can be significantly reduced. Several, for example, two, dosing racks can be mounted and / or attached to the base frame. Finally, accessibility to all components of the screw extruder can also be improved, particularly through the linear guide, which allows for an unused dosing unit to be easily moved away.

[0026] Figs. 1 and 2 show a dosing frame 100 for positioning a dosing device 102. The dosing device 102 is designed for dosing a material and / or additive to be processed by at least one screw extruder. The dosing frame 100 has a multi-axis linear guide 104. In the present embodiment, the linear guide 104 is biaxial and designed as a linear extension 104. The linear extension 104 has a guide rail and a running axis slidably received therein. The dosing frame 100 can be linearly moved or displaced by means of the linear guide 104.

[0027] Furthermore, the dosing frame 100 has an adjusting device 106, which is designed for positioning, in particular for pivoting and adjusting a height, of the dosing device 102. The adjusting device 106 comprises a pivoting mechanism 108, by means of which the dosing device 102 can be pivoted and / or rotated about a vertical axis of rotation 110. In addition, the adjusting device 106 has a leveling mechanism 112 for leveling the dosing device 102. For example, the leveling mechanism 112 can comprise adjustable screw connections. In the present embodiment and as shown in Figs. 1 and 2, the screw connections can each have two nuts and a threaded rod, which interact with one another in such a way are arranged so that leveling or raising and / or lowering of a support plate 1 14 can be carried out.

[0028] As shown in Figs. 1 and 2, the dosing frame 100 comprises a support plate 114. The dosing device 102 is mounted on this support plate 114. For example, the dosing device 102 can be fastened to the support plate by means of screws or the like. The support plate 114 can be pivoted and / or rotated about the vertical axis of rotation 110 by means of the adjustment device 106 and can be leveled vertically relative to a horizontal plane. The displacement, pivoting, and leveling are illustrated by the arrows in Figs. 1 and 2.

[0029] Figs. 3 to 6 now show an extrusion device 1 16 in perspective view (Figs. 3 and 4) and in side view (Figs. 5 and 6).

[0030] The extrusion device 116 shown in Figs. 3 to 6 comprises a screw extruder 118 for processing material, such as plastic material. The screw extruder 118 is designed as a twin-shaft screw extruder and has two treatment element shafts mounted in a cylinder housing 120 for plasticizing and / or mixing and / or homogenizing the material fed into the screw extruder 118. The treatment element shafts are rotatably driven by a drive motor 122 via a gear 124.

[0031] The extrusion device 116 further comprises a base frame 126, such as a machine base frame. The screw extruder 118 is mounted on the base frame 126. In the present exemplary embodiment, the screw extruder 118 or its cylinder housing 120 is supported and secured to the base frame 126, in particular to the top side of the base frame 128, via supports 128. Furthermore, the drive motor 122 and the gear unit 124 of the screw extruder 118 are also mounted and secured to the base frame 126, here also to the top side of the base frame 126.

[0032] A feed screw machine 130 is provided for feeding an additive into the screw machine 118. For this purpose, the screw machine 118 has a side opening to which the feed screw machine 130 is connected. As a result, the feed screw machine 130 is connected to the screw machine 118 in such a way that the additive can be fed into the screw machine 118. The feed screw machine 130 is designed as a side-feeding screw machine and is also mounted and secured to the base frame 126, here on the top side of the base frame 126.

[0033] As shown in Figs. 3 to 6, the extrusion device 1 16 has two dosing racks 100. The dosing racks 100 are designed essentially as described above and / or below, for example as shown with reference to Figs. 1 and 2. Therefore, two essentially identically designed dosing frames 100 can be provided. A dosing device 102 for dosing a material or additive to be processed by the screw extruder 118 is attached to each dosing frame 100. The dosing devices 102 can be essentially identical or differently designed. For example, one dosing device 102 can be assigned to a main feed hopper 132 of the screw extruder 118, and the other dosing device 102 can be assigned to an inlet hopper 134 of the side-feeding screw extruder 130. As a result, the material to be processed can be fed in a metered manner to the main feed hopper 132 of the screw extruder 118, and the additive can be fed to the feed hopper 134 of the side-feeding screw extruder 130.

[0034] In the present embodiment, the dosing racks 100 are mounted on the base frame 126. As can be seen in Figs. 3 to 6, the dosing racks 100 are mounted laterally on the base frame 126 or are attached laterally to the base frame 126 via the linear guides 104 on two opposite sides of the base frame 126 and are movable in the longitudinal direction 136 of the base frame 126. As a result, the dosing racks 100 and thus the respective dosing device 102 can be moved or displaced linearly in the longitudinal direction 136 of the screw machine 118, in particular in the longitudinal direction 136 of the cylinder housing 120, and in the longitudinal direction 136 of the base frame 126. The dosing racks 100 are thus used to position the respective dosing device 102 relative to the base frame 126 and relative to the Screw machine 1 18 or side-feeding screw machine 130.

[0035] The dosing frames 100 each comprise the adjusting device 106 for positioning, in particular pivoting and adjusting a height, of the respective dosing device 102 relative to the screw machine 118 or side-feeding screw machine 130. By means of the pivoting mechanism 108 of the adjusting device 106, the respective dosing device 102 can be pivoted about the vertical axis of rotation 110 into a dosing position (illustrated by the arrow in Figs. 3, 4 and 5), in which the dosing device 102 is connected to the main feed hopper 132 of the screw machine 118 or to the inlet hopper 134 of the side-feeding screw machine 130 for the metered supply of the material or additive. With the help of the leveling mechanism 112 of the adjustment device 106, the dosing device 102 arranged on the carrier plate 114 can then be leveled in order to enable height compensation.Thus, the respective dosing device 102 at the main feed hopper 132 of the screw conveyor 118 or at the inlet hopper 134 of the side-feeding screw conveyor 130 can be precisely and easily positioned simply by sliding and pivoting. Advantageously, the pivoting mechanism 108 of the adjusting device 106 also allows the respective dosing device 102 to be pivoted away from the screw conveyor 118 or the side-feeding screw conveyor 130 into a cleaning or parking position. Additionally or alternatively, the linear guide 104 can also be used, which can be configured to move or push the dosing device 102 away from the screw conveyor 118 or the side-feeding screw conveyor 130 into a cleaning or parking position. The dosing frames 100 thus enable universal usability and positioning of the dosing devices 102.

[0036] Furthermore, reference is made in particular to Figures 1 and 2 and the associated description.

[0037] Figs. 7 to 11 show a variant of a dosing frame 138. In contrast to the dosing frame 100 according to Figs. 1 and 2, the linear guide 104 of the dosing frame 138 according to the present embodiment according to Figs. 7 to 11, instead of the running axes, has runners 140 which are slidably received in the respective guide rail 142 (shown in detail in Figs. 9 to 11). The two vertically spaced guide rails 142 can be fastened to the base frame 126 and the runners 140 are fastened to a vertical axis 144 of the dosing frame 138. Furthermore, the runners 140 are coupled to the guide rails 142 such that the runners 140 can be moved in their respective guide rail 142 along and substantially within the guide rail 142. As a result, the vertical axis 144 of the dosing frame 138 can be moved linearly along the guide rail 142.

[0038] Furthermore, the linear guide is lockable or lockable. In the present embodiment, the runners 140 are lockable or lockable. For this purpose, a fastening device 146 designed as a toggle lever mechanism is provided for each runner 140. The fastening device 146 is designed to fix or lock the respective runner 140 to the associated guide rail 142. For this purpose, for example, the manual actuation of a lever 148, such as an actuation lever, of the fastening device 146 is sufficient. Moving the dosing frame 138 is then no longer possible. Moving can only occur again after the lever 148 is actuated again or released.

[0039] The support plate 114 of the dosing frame 138 further has recesses 150, here four recesses 150. The recesses 150 are designed for positioning and / or displacing the support plate 114 in a plane extending substantially horizontally. In the present exemplary embodiment, the recesses 15 are designed as elongated holes. As shown in Figs. 10 and 11, the threaded rods 152 of the screw connections of the leveling mechanism 112 protrude through the recesses 150 and can be fastened to the support plate 114 by means of nuts, but can also be released again so that the threaded rods 152 can slide within the recesses 150. This also allows a dosing device 102 arranged on the support plate 114 to be positioned and / or displaced in the plane extending substantially horizontally.

[0040] Furthermore, reference is made in particular to Figs. 1 to 6 and the associated description.

[0041] Figs. 12 to 14 show a variant with two dosing racks 138 on a common linear guide 104. For this purpose, two runners 140 are each coupled to a guide rail 142, in particular such that the two runners 140 can be displaced individually and / or together along and essentially within a common guide rail 142. In the present exemplary embodiment, two runners 140 are thus displaceably received on each guide rail 142. Furthermore, the runners 140 of a guide rail 142 are each fastened to a vertical axis 144 of the associated dosing rack 138. The two dosing racks 138 can thus be moved linearly along the common guide rails 142 by means of the common linear guide 104, for example individually, simultaneously, relative to one another and / or together.

[0042] Furthermore, reference is made in particular to Figs. 1 to 11 and the associated description.

[0043] Figs. 15 to 18 show a variant of an extrusion device 154 in perspective view (Figs. 15 and 16) and in side view (Figs. 17 and 15).

[0044] The extrusion device 154 according to the present embodiment essentially corresponds to the extrusion device 116 described and illustrated with reference to Figs. 3 to 6. As shown in Figs. 15 to 18, the extrusion device 154 now has two dosing racks 138 instead of the dosing racks 100, which correspond to the dosing rack 138 illustrated and described in Figs. 7 to 11. The dosing racks 138 of the extrusion device 154 are thus essentially designed as described above with reference to Figs. 7 to 11.

[0045] The dosing racks 138 are also mounted laterally on the base frame 126 or are attached to the base frame 126 via the linear guides 104 on two opposite sides of the base frame 126 and are movable in the longitudinal direction 136 of the base frame 126. However, the linear guides 104 have the sliders 140, which are slidably received in the respective guide rail 142. Furthermore, for each runner 140, a fastening device 146 designed as a toggle lever mechanism is provided in order to be able to fix or lock the runners 140.

[0046] Furthermore, reference is made in particular to Figs. 1 to 14 and the associated description.
