Description

Bale opener for opening pressed fiber bales with an improved basic structure

description

The invention relates to a bale opener for opening pressed and erected in an erection fiber bale, with a machine frame and a pickup unit, wherein the pickup unit is vertically adjustable on the machine frame and wherein the machine frame is movable in the installation direction, so that the fiber bales are traversable with the pickup unit and fiber material is removable from the fiber bales.

DE 37 34 480 A1 or DE 36 37 578 A1 disclose a bale opener for opening pressed and erected in an installation direction fiber bales, and the bale opener has a machine frame on which a pickup unit is arranged vertically adjustable. The machine frame is movable in the Aufstellrichtung of Faserbalien, so that the fiber bales are traversable with the pickup unit and fiber material can be removed from the fiber bales. For this purpose, the pickup unit has a pickup roller, which is set in rotation and removes fiber flakes from the fiber bales, after which the fiber flakes are transported away via a suction device.

In the construction of bale openers is a continuous operation in the foreground, so that the fiber bales can be set up as possible without interrupting the operation of the machine, while the bale opener of other established fiber bales decreases the fiber flakes without interruption. This results in a necessary loading of the bale opener with fiber bales, which usually have to be placed in their Aufstellrichtung in a Aufstellgasse. The machine frame moves as long as the fiber bales until they are almost completely removed, and subsequently changes the Machine frame by a movement in the direction of erection to the subsequently established fiber bales to continue the removal process. Depending on the spatial conditions, the placement of the fiber bales in the Aufstellgasse is expensive, especially since the fiber bales must be moved with industrial trucks.

The known bale openers have for this purpose on a floor mounted and spaced apart rails on which the machine can move in the direction of erection. It is disadvantageous if a material handling vehicle has to travel over laid on the floor rails, so often the way is taken directly into the Aufstellgasse without overrunning the rails. Especially with several parallel operated bale openers results in a complicated logistics for feeding each of the bale opener with the fiber bales, when a corresponding number of rails is laid on the ground.

Known designs of bale opener machine frames include a steel girder construction with drives for the various movements of the bale opener disposed on the girder structure. For example, motors for height adjustment of the customer, and motors for moving the machine frame in the installation direction are arranged on the upper side of the machine frame. To control the bale opener, however, electrical control units are necessary, which must be placed externally due to the reduced construction of the machine frame, so that they must be operated as peripheral equipment. Consequently, long cable runs are necessary, which are disadvantageous in particular for the operation of the sensors and the power units, such as the travel motors.

The object of the invention is to improve the basic construction of a bale opener for opening pressed fiber bales. In particular, it is the task of Invention to simplify the loading of bale opener with fiber bales and / or increase productivity.

Another object of the invention is to constructively optimize the machine frame of the bale opener so that the machine frame accommodates as much as possible the essential functional units for operating the bale opener.

These objects are achieved on the basis of a bale opener according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that the machine frame has a gantry design with a first side cheek and with a second side cheek, wherein the first side cheek is guided on a running rail and wherein the second side cheek is guided on a floor on which also set up the fiber bales are.

The basic idea of the invention is a merely one-sided guidance of the machine frame in the erecting direction, which nevertheless is designed in gantry construction. As a result, the bale opener only comes with a single track for guiding the machine frame, while the second side cheek is guided only above the ground and thus only in the vertical direction. The running rail opposite area of the bale opener can thus be performed with a continuous, uninterrupted ground, so that the fiber bales not only have to be placed through a Aufstellgasse, but the fiber bales can also be supplied from the side to Aufstellrichtung to the bale opener. It has been found that only one-sided guidance of the machine frame in gantry design is sufficient, especially when two spaced apart on the first side cheek rollers arranged are guided on the running rail, and two more on the second Sidewalls recorded rollers can roll over the ground, without the need for another track would be necessary. Further components of the bale opener, in particular the guidance of the suction air, can be arranged on the side of the first side cheek, for example parallel behind the running rail, so that the setting-up area for setting up the fiber bales can sufficiently have, for example, only one delimiting mark, without these having any other base structures ,

A particular advantage is achieved if the running rail is designed for mounting on the same floor on which the second side cheek is guided. In particular, so that the running rail is also designed for mounting on the floor on which the fiber bales are placed. Due to the gantry design of the machine frame, however, the running track does not have to take up any moments, and the pickup unit does not have to be designed as a unit protruding from a tower, so that no major moments arise which have to be compensated, for example, by counterweights. Nevertheless, there is the same advantage of the free loading of fiber bales, as this is also known for laterally projecting Abnehmereinheiten, which are added to a pickup tower adjustable in height. In addition, the customer can be carried out longer than in the tower design, whereby the productivity of the bale opener, for example, can be increased to 2,500 kg / h.

The gantry design of the machine frame is designed so that between the side walls two parallel portal profiles are arranged, which extend in a transverse direction of the machine frame and which are connected with their ends in the region of the upper corners of the side cheeks to this.

The design of the portal profiles and the only end attachment of the portal profiles to the side walls allows an embodiment of the machine frame with a deliberately limited torsional stiffness of the two side cheeks in the transverse direction to each other, so that occurring unevenness Do not cause the floor arranged under the side rollers to roll on the track and for rolling on the ground lose the rail contact or the ground contact. The portal profiles form a desired compliance for connecting the two side cheeks, but the directional stability is maintained for moving the machine frame in the installation direction. The side cheeks can rotate each other in small angular ranges about a transverse axis, with excessive tension in the machine frame or in the portal profiles or their connection to the side walls remain suppressed.

Another particular advantage arises from the fact that the pickup unit can be added hanging at least indirectly to the portal profiles. It may be sufficient that the pickup unit between the side cheeks is guided only to this, but the weight of the pickup unit is taken over the portal profiles. In particular, it has proved to be advantageous to arrange bridge elements between the Protalprofile, for example in the vicinity of the respective end side of the portal profiles and thus adjacent or close to the side cheeks, the pickup unit is added, for example, with traction means hanging on the bridge elements, the bridge elements in turn of the Portal profiles are worn. The portal profiles are located in the corners of the side walls, and the traction means are centrally located between the portal profiles on the bridge elements.

It is of further advantage if the traction means as possible spaced apart record the pickup unit, so that the traction means are arranged for example on the outside of the pickup unit and thus close to the side cheeks. The pickup unit extends substantially only between the inner sides of the two side cheeks, and the pickup unit is not guided into the side cheeks, in particular not with fastening means for receiving a weight force. A particular advantage of the portal construction with respective side cheeks is that in each case a receiving space may be formed in the side cheeks, are received in the means for operating the bale opener. For example, a drive unit for generating the movement of the machine frame can be arranged in the first side cheek. It is also conceivable that at least one electrical control unit for controlling the bale opener is arranged in the second side cheek. Thus all essential functional units for operating the bale opener are already accommodated in the machine frame, and a peripheral electrical control unit can essentially be dispensed with. This results in short cable connections, in particular between the control unit and sensors, motors, actuators and the like, so that a simple construction and reliable operation of the bale opener are ensured.

A particular advantage is achieved if at least one, but preferably two, driven by the drive unit rollers are accommodated on the first side cheek, which roll for receiving the respective, first or second side cheek on the track rail or on the floor. On the second side cheek, two rollers may be arranged, which are arranged to roll on the floor for guiding the second side cheek. This results, for example, four rollers arranged on the machine frame, which receive the weight of the machine frame and in particular the pickup unit substantially uniformly. The guide on the floor means guiding the second side cheek on the surface of the floor.

The side cheeks can be designed so that they have lateral dimensions which are wider than the width of the pickup unit. The width is the dimension of the respective side wall horizontal to the floor or the running rail along the direction of movement of the bale opener when driving over the fiber bales Thus, the distance between the rollers on the respective side cheek can be increased, which the stability and thus the stability the bale opener benefits. In addition, the passive safety increases, since it is more difficult, for example, with a floor vehicle from the long side of the bale opener ago, so essentially transversely to its travel ,, to reach the customer and thus in the dangerous area of the bale opener. In addition, the side bolsters provide space for sensor technology, which benefits active safety. Additionally or alternatively, maintenance windows are introduced in the side walls, through which accessibility of the pickup unit is created. For this purpose, the pickup unit must be driven only to the height corresponding to the height of the maintenance window, so that the accessibility of the pickup unit is granted. For example, the maintenance windows can be formed above the arrangement of the electrical control unit and above the arrangement of the drive unit in the side walls.

Furthermore, a suction device with a channel for guiding the suction air is present. The suction device is arranged with a channel in the side remote from the mounting area outside parallel to the running rail. In particular, with further advantage, a power and signal connection is established on the channel of the suction device, wherein the power and signal connection may comprise a cable chain device. The power and signal connection is more advantageously located on the outside of the channel, such that the track is on a first, inner side of the channel and the power and signal connection is on a second, opposite, outer side of the channel. In particular, the bale opener can be placed with the side of the suction device and the power and signal connection adjacent to a building wall, since accessibility of the bale opener from this side to operate the bale opener is not permanently required. Further measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS. It shows:

2 is a second perspective view of the bale opener with the features of the invention,

3 is a perspective view of the bale opener with an open second side cheek,

4 is a perspective view of the bale opener with an opened first side cheek, and

Fig. 5 is a perspective view of the bale opener in a sectional view.

Figures 1 and 2 show in two different perspective views of a bale opener 1 with the features of the present invention. The bale opener 1 is used for top-side milling of fiber bales 100, which are placed in a set-up area 28 on a floor 16 in a plurality of rows next to each other in an installation direction 10. For milling off the upper side of the fiber bales 100, a pickup unit 12, which is received on a machine frame in a vertical direction vertically in FIG. 1 on the floor 16 to or away from it, serves. The machine frame 1 1 has a first side wall 13 and second side wall 14. Between the two side walls 13 and 14, two spaced apart portal profiles 17 extend.

The side cheeks 13, 14 have rollers 22 and 23, and for guiding the machine frame 11 in the installation direction 10 is a running rail 15, on the For example, the rollers 22 are guided on the first side wall 13. The rollers 23, which are located on the second side wall 14 on the underside, run over the bottom 16, on which the fiber bales 100 are placed, and on which preferably also the running rail 15 is mounted.

The pickup unit 12 has, for example, on an underside two pickup rollers 31 and three support rollers 32. The doffer rollers 31 are located between the support rollers 32, and the axes of rotation of all the rollers 31, 32 are parallel to each other in the transverse direction 18. In front of the doffer rollers 31 are gratings 33. When the rollers 31, 32 are rotated, the doffer rollers 31 take flake-like Components from the pressed fiber bales 100, and the fiber flakes are sucked through the suction device 26 and fed to their further use.

The suction device 26 comprises a suction hood 34, which is located on the upper side of the pickup unit 12 and to which a vertically upwardly leading spiral tube 35 connects. In a vertical process of the pickup unit 12, the spiral tube 35 may vary in length, and the spiral tube 35 is connected to the top side of a suction air duct 36, which introduces the suction air in the first side cheek 13 on the upper side. Thus, the suction air duct 36 is connected self-supporting at the top of the first side wall 13, and the spiral tube 35 is in a hanging arrangement at the end of Saugluftschachtes 36. The suction air passes through the first side wall 13 and passes through a channel 27 together with the fiber flakes a processing station.

The manual control of the bale opener 1 via a control panel 37, which is set up by way of example on a head side of the channel 27. The electrical supply of the bale opener 1 via a junction box 38, which is located at the same head end of the channel 27. Via a power and signal connection 29, comprising a cable chain unit 30, an electrical Supply and a signal connection with the movable machine frame 11 are made, with the power and signal connection 29 is laterally on the channel 27. A driver 39 forms the movable connection of the channel chain unit 30 and is connected to a band lifting unit 40, which is connected to the first side wall 13 and consequently moved with the movement of the machine frame 11 in the installation direction 10. The bath lifting unit 40 is used to lift a cover band 45, which covers the channel 27 on the top.

In Fig. 3 is a further perspective view of the bale opener 1 is shown, wherein the second side cheek 14 is shown open. The side cheeks 13, 14 each have a receiving space, are received in the means for operating the bale opener 1. Advantageously, the electrical control unit 21 of the bale opener 1 is integrated in the second side wall 14, with the electrical control unit 21 monitoring and controlling the essential movement functions and the sensors and the associated actuators of the bale opener 1. Thus, the machine frame 1 1 is adapted to receive the essential functional means for operating the bale opener 1, wherein advantageously the electric control unit 21 is arranged on the free, second side wall 14. The receiving space can be made accessible with doors, not shown, with the accessibility is given optimally in particular by the free-standing second side cheek 14. An operator can thus access the electrical control unit 21, wherein in an unillustrated manner, in particular an input-output interface can be arranged on the second side wall 14, which are redundant in terms of their function, additionally designed and / or complementary to the control panel 37 can.

The pickup unit 12 is received by means of pulling means 25 on the bridge elements 19 of the machine frame 11, and the bridge elements 19 are arranged on the portal profiles 17 extending parallel to each other. The traction means 25 form drawstrings with integrated Stahlzugträgern, and the traction means 25 are wrapped around the deflection elements 42 received on the bridge elements 19 around.

4 shows another perspective view of the bale opener 1 with the machine frame 11 comprising the first side wall 13 and the second side wall 14, the perspective showing the first side wall 13 in an opened arrangement. The essential components that are received in the first side wall 13 include the drive unit 20 for driving the rollers 22, which are driven by the drive unit 20 by means of a belt 41. The illustration shows the pulleys, which are applied on the front side on the rollers 22 and thus cover the latter.

Furthermore, a portion of the suction device 26 is received in the first side wall 13, and the suction air duct 36 passes through an upper roof area of the first side wall 13 and continues with a removable shaft segment 43 in the first side wall 13, to finally reach the band lifting unit, not shown ,

Fig. 5 shows a sectional view of the bale opener 1, and the section extends through the portal sections 17 and by the pickup unit 12. The rear side, the first side wall 13 is shown, via which the electrical contacting of the movable machine frame 11 takes place. The machine frame 11 in particular with the portal profiles 17 serves to guide power and signal cables, for which the portal profiles 17 comprise hollow chambers 44 through which the power and signal connections are continued, which are connected to the power and signal connection 29 of FIG , In this way, the electric control unit 21 can be contacted via the portal profiles 17, and power and signal connections are guided back to the first side wall 13 via the hollow chambers 44 in the portal profiles 17, in particular for controlling and operating the drive unit 20. This results short conduction paths between the junction box 38, as shown in Figs. 1 and 2, and the electrical Control unit 21 in the second side wall 14, to which the power and signal lines are passed through the hollow chambers 44. Preferably, shielded signal lines are advantageously led through a portal profile 17 and power lines through the other portal profile 17. Thus, a so-called crosstalk between power and signal lines can be safely prevented or avoided.

The invention is not limited to its execution on the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. Any features and / or advantages resulting from the claims, the description or the drawings, including constructional details or spatial arrangements, can be essential to the invention both individually and in the most diverse combinations.
