[0001] Bale machine'

[0002] Description:

[0003] The invention relates to a baling machine for handling materials of all kinds which are pressed into bales and for which comminution or separation is provided, according to the features in the preamble of claim 1 and to a method for handling such bales according to claim 22.

[0004] In the context of recycling, for example, waste materials, particularly paper, cardboard, plastics, or the like (hereinafter collectively referred to as materials), are collected, shredded if necessary, and pressed into round or square bales so that they can be transported as reduced-volume fabric bales and stored in a space-saving manner. Or, for example, rejects as a product of defective production, which are still unused, usually unshredded, but defective, such as nonwovens with faulty printing or the like, are pressed into bales. During the recycling process, the bales, which can weigh up to 1,000 kg or more, are broken down again using shredders, bale breakers, or the like (hereinafter referred to as shredding equipment), whereby the materials themselves can be shredded or separated.Feeding a shredding device with pressed bales can be important for downstream processing, for example, to ensure continuous and homogeneous material availability.

[0005] US 9,163,191 B2 discloses a non-generic feeding device comprising several conveyor belts arranged one behind the other in the process flow, which feed pressed bales consisting of plant material to a shredding device. However, it is common practice, particularly in the processing of waste materials, for the feed openings on high-performance shredding devices to be arranged above the shredding tools, such as the drum of a shredder equipped with cutting tools or the like, so that a level feed, as known from US 9,163,191 B2, is not possible. Therefore, the previously known feeding devices have a feed unit designed as a ramp-like conveyor, with the ramp incline generally not exceeding 30° to prevent the pressed bales from rolling down.The low gradient means that the known loading devices are very space-intensive due to the necessarily long loading ramps.

[0006] The loading or transfer of bales to the loading device is typically carried out by industrial trucks, for example a forklift, which picks up the bales and transports them from a storage location to the loading device in short cycle times. It is often necessary to transport several bales simultaneously, stacked on top of each other, to maximize the utilization of the shredding equipment. Transporting and depositing multiple bales is risky, as it restricts the visibility of the industrial truck driver and allows the stacked bales to easily fall off. Furthermore, to ensure high utilization, loading machines are preferably operated in labor-intensive multi-shift operations.

[0007] The loading devices known from practice share the problem that they require a lot of space and are only economically viable to a limited extent. To increase efficiency, additional personnel input is required, which can sometimes expose personnel to significant safety risks.

[0008] The present invention is based on the objective of improving the known method, particularly with regard to the aforementioned problems. The aim is to increase cost-effectiveness by ensuring high process reliability in the processing of pressed materials. Furthermore, the risk of accidents for operating personnel is to be minimized.

[0009] This object is achieved by a bale forming machine according to the features of claim 1 and by a method according to the features of claim 22. Features of the invention are discussed below, with further inventive embodiments of the invention being described, inter alia, in the subclaims. These design features can be implemented in conjunction with the invention or can be independently inventive, independent of the invention, and they can be implemented either individually and independently of one another or in any desired combination, including the implementation of all of the aforementioned features, unless a combination is expressly or technically mandatory.

[0010] The invention proposes a baling machine for handling pressed bales that are to be fed to a shredding device in preparation for further processing steps. The present proposal is essentially based on the idea of ​​mechanical and preferably largely automated bale handling.

[0011] According to the proposal, the bale automatic machine has a loading device with a feed unit, wherein the feed unit is designed as a lifting unit. Within a space referred to as the operating space of the lifting unit, bales can be handled by the lifting unit, in particular by the bales being lifted up or down from a support surface forming a first level. In the simplest case, a hall floor or the like, on which the shredding devices are also arranged, forms the support surface, wherein the lifting unit can only lift or down a bale within the operating space, for example due to design features of the lifting unit or structural features in the working environment of the lifting unit which limit the operating space. The operating space of the proposed lifting unit is large, although the installation space required for it is comparatively small compared to known loading ramps. The design of one or more operating spaces orThe coordination of multiple action areas is a key consideration of the present invention. The feed unit, designed as a lifting unit, lifts a bale from the support surface to a second level located above the first, so that it can be fed to a shredding device.

[0012] Lifting devices such as cable crane-like systems, hydraulically operated booms, or the like can be provided as a lifting unit. These essentially hold a bale, for example using bale tongs, bale grippers, bale forks, bale troughs, or the like, and lift them and feed them to a shredding device. Bale tongs, bale grippers, and bale forks are widely known in practice and are particularly suitable. A bale trough can be advantageous if materials released from a bale are to be collected and lifted and fed with the bale, preferably with bales of inferior pressed quality or with very small or particulate materials, particularly when handling waste materials. The proposed lifting unit eliminates the need for a ramp-like design, thus requiring significantly less installation space, which is economically advantageous.In contrast to the known ramp-like feed unit, the proposed lifting unit enables controlled feeding of a bale into the feed opening of a shredding device. This allows, firstly, the lifting height that must be overcome to feed a bale into a shredding device to be reduced, particularly by reducing the height of the shredding device's feed hopper. Secondly, the controlled feeding reduces the likelihood of bales becoming jammed and stuck in the feed hopper, which in practice regularly requires risky personnel intervention. Thus, according to the proposal, process reliability can be increased and personnel costs reduced, for example, in an economically advantageous manner.

[0013] The invention is based on the idea of ​​proposing a bale dispenser as a buffer storage unit in order to reduce the personnel required to operate a material processing plant, in particular waste materials, while at the same time increasing occupational safety. According to the proposal, the operating space of the lifting unit is crucial in that all bales located in the operating space can be temporarily stored as a buffer before they are fed to a shredding device by means of a lifting unit. The buffer storage unit makes it possible, for example, to keep a certain quantity of bales available for a shredding device or to temporarily store them to bridge a period of time, so that continuous feeding by means of an industrial truck is unnecessary and personnel can be saved. The size of the operating space is positively correlated with the bridgeable period of time.Furthermore, the proposed bale dispenser increases the occupational safety of operating personnel. Firstly, the risk of bales weighing up to 1000 kg rolling down a ramp and injuring personnel is eliminated. Secondly, bale transport safety is increased, as the proposed solution eliminates the need to transport multiple bales stacked on top of each other, which would restrict the visibility of the industrial truck driver, from a storage location to a loading device. Instead, the storage capacity of the proposed operating area can be expanded accordingly, on the one hand to hold the bale quantity required for continuous feeding of a shredding device, and on the other hand, to eliminate the need for simultaneous transport of multiple bales by industrial truck to provide the required bale quantity.

[0014] In a particularly advantageous embodiment, the feeding device can have a conveyor unit with a carrying surface provided for receiving the bale. The carrying surface can be formed, for example, by a chain conveyor, roller conveyor, conveyor belt or the like, on which bales can be received or carried in one or more layers. The conveyor unit creates a conveyor line, which in turn creates an operating space for the conveyor unit and opens into the operating space of the lifting unit, such that a bale can be conveyed on the conveyor unit towards and up to the lifting unit. Alternatively, it may be sufficient for the conveyor line to end at the operating space of the lifting unit, such that a bale conveyed to the lifting unit can be grasped and lifted by the lifting unit, even though the conveyor line ends outside the operating space of the lifting unit.The conveyor unit advantageously increases the buffer storage without requiring an increase in the operating space of the lifting unit. Instead, the operating space of the lifting unit could be reduced, or a smaller operating space of the lifting unit is sufficient to hold a corresponding bale quantity. Advantageously, the receiving capacity of the conveyor unit is structurally adapted to a time period to be bridged, for example by extending the conveyor unit or by the height of the bales stacked on top of each other, so that the receiving capacity of the conveyor unit can be aligned to a bale quantity that a shredding device can process, for example, at night, thus eliminating the need for labor-intensive feeding during night shifts.

[0015] A combination of a lifting unit and a conveyor unit is particularly suitable for retrofitting existing systems. The design of the lifting unit and the conveyor unit, and thus the design of the respective operating spaces, must be specifically tailored to the given structural limitations. By adapting the operating space of the lifting unit, the operating space of the conveyor unit, and / or the capacity of the conveyor unit, economically advantageous individual solutions for improved feeding of a shredding system can be created.

[0016] In one embodiment, it can be provided that the lifting unit has a bale holding element and that the lifting unit and / or the bale holding element are pivotally movable, particularly when the lifting unit is arranged locally in the space between a conveyor unit and a shredding device. In particular, mobility aligned about a substantially horizontal pivot axis can be provided so that a bale deposited in front of the lifting unit or located on the conveyor unit can be grasped, lifted over the lifting device, and fed from above into a feed opening of a shredding device, wherein the lifting and feeding can advantageously be carried out solely by the pivoting movement.

[0017] It is particularly advantageous if several conveyor units are arranged side by side. This allows the storage capacity of the buffer to be increased accordingly. Furthermore, bales with different characteristics, such as the type of material, weight, degree of contamination, moisture content, or similar, can be pre-sorted and stored temporarily, thus economically maximizing the amount of largely homogeneous shredded material that can be produced.

[0018] In one embodiment, the lifting unit can be designed to be movable, for example to increase the operating space or to feed multiple comminution devices, or, if the lifting unit is arranged locally between a conveyor unit and multiple comminution devices, between multiple conveyor units and a comminution device, or between multiple conveyor units and multiple comminution devices, so that the utilization of the lifting unit can be increased in an economically advantageous manner and, at the same time, the investment costs for multiple conveyor units or comminution devices can be reduced. The mobility can preferably be achieved by mounting the lifting unit on rollers, wheels, or the like.

[0019] In an advantageous embodiment, the bale dispenser can have a loading station with a loading section in the form of a loading platform, which can be approached by a driver of an industrial truck and on which a bale can be placed in order to feed it to the conveyor unit and thus transfer it to the intermediate storage area. For this purpose, the loading platform can be provided, for example, with roller conveyors or the like. Advantageously, the loading station can also have a baffle wall, which serves to align several bales stacked on top of one another, in particular by means of an industrial truck, in order to ensure the most stable storage possible on the support surface.

[0020] In a particularly advantageous embodiment, a control device can be provided for the greatest possible automation of the bale machine, wherein the automation can, for example, relate to the feeding of the bales into a shredding device in response to a request signal. The automated feeding can economically advantageously increase the utilization of a shredding device by feeding a bale by means of a lifting unit, avoiding idle times of the shredding device, as soon as the shredding of a previously fed bale has progressed sufficiently and a new feed is possible, thus triggering a request signal. A request signal can be generated step by step as soon as a certain threshold value is reached, exceeded, or undershot.The threshold value is advantageously defined by characteristics of the shredding device, for example, by its load capacity, so that damage to the shredding device can be prevented and / or the most economical operation of the shredding device can be achieved. Provision can be made to generate a request signal after a specific period of time has elapsed. At the same time, such control is advantageous for avoiding peak loads on the shredding device and instead enabling a largely homogeneous load to be achieved, thus increasing service life and saving energy. Automation is also advantageous for operating the bale machine largely without personnel, thus reducing the risk of accidents.

[0021] The aforementioned advantages can be further enhanced if the control device controls additional components of the bale machine. It can preferably be provided that the control device connects the feed unit to the conveyor unit for signal transmission, so that bales can be automatically conveyed to the lifting unit and bales can be fed to a shredding device. Conveying a bale can be provided particularly when there are no or only a few bales left in the operating space of the lifting unit. Advantageously, the control device can contribute to the optimized coordination of operating spaces while conserving installation space by means of a controlled loading device.

[0022] For example, for economical recycling, information regarding the characteristics of waste materials is of great importance, such as the origin and type of waste materials, the degree of contamination, the weight, the moisture content, or the like. Therefore, in one embodiment, a detection device can be provided that has a reading element to read information stored on storage media arranged on the bale, for example, an RFID transponder. This makes it possible to trace the composition of a batch of shredded materials at any time, even if several bales are shredded (one after the other) and the shredded materials form a common mixture or batch.

[0023] The recorded information can, for example, be used to sort the temporarily stored bales according to characteristics on the support surface or on the support surface of the conveyor unit, particularly when multiple conveyor units are arranged. In this embodiment, the detection device can advantageously be arranged at the feed station in order to immediately detect a fed-in bale and assign it accordingly. In the sense of comprehensive space management, material flows can be stored in a comprehensible manner on the basis of the detection device and thus made traceable. It can also be provided that the lifting unit has a detection device, preferably when multiple shredding devices are arranged downstream of the lifting unit, for example in order to feed bales with specific characteristics to the same shredding device. On the one hand, this is beneficial for homogeneous process conditions.On the other hand, this promotes the production of a largely homogeneous, crushed or separated material.

[0024] For economically advantageous utilization of a shredding device, one embodiment can provide a monitoring device that serves to determine the bale fill level in the shredding device. If it is detected that the shredding device has free capacity to accommodate another bale, a request signal can be generated so that the control device controls the conveyor unit or lifting unit accordingly to feed the shredding device with another bale.

[0025] To detect the fill level, the monitoring device can, for example, have a camera, and the evaluation can be carried out with software support. In one embodiment, lasers, ultrasound, or the like can be used to determine the fill level and, based on this, to generate a request signal with software support. In particular, working data of the comminution device, for example an acting torque, a current drive power, or the like, can be an indication of a quantity of material being processed in the comminution device at a specific time. It can therefore be particularly advantageous for the monitoring device to have a coupling element in order to be able to record or receive such working data and, if necessary, to derive a request signal from it for controlling the feeding device.

[0026] The baled materials are regularly bound using wire, plastic fibers, film, net, or the like. To ensure the materials are as homogeneous as possible and to avoid unnecessary strain on the shredding tools, binding agents should be removed from the bale and preferably separated from the materials before the bale is fed to a shredding device. Since manual separation poses a high risk of accidents for personnel due to the high pre-tension of the binding agents, a binding agent remover can advantageously be provided. This removes the binding agents out of the reach of personnel before a pressed bale is fed to a shredding device and, if necessary, separates the binding agents from the bale material.Advantageously, the binder remover can be arranged adjacent to, i.e., within the operating space of, the lifting unit, so that, for example, a bale lifted by the lifting unit can be removed and then fed in a controlled manner to a feed opening of a shredding device. In this sense, the binder remover can advantageously be arranged in a vertical extension substantially above the feed opening so that any material falling during removal falls into the feed opening due to gravity.

[0027] Particularly due to the high investment costs for a binder remover, it may be economically advantageous to arrange a binder remover in such a way that bales are removed before lifting and the removed substances are transferred into a bale trough of the lifting unit. The lifting unit is advantageously movable and arranged on a crossbeam, and is preferably designed to feed multiple shredding devices. The removed substances can be metered in via the bale trough, ensuring optimal utilization of the shredding devices.

[0028] In one embodiment, a dosing device with a conveying part can be provided, which is intended to first receive a loosened bale and to be able to feed the materials to a comminution device in a dosed manner, for example in such a way that individual press layers are fed, which are formed by a press piston stroke when the materials are pressed.

[0029] In a particularly advantageous embodiment, the lifting unit can be arranged on a crossbeam, wherein the crossbeam is designed as a portal or bridge element. To increase the operating space of the lifting unit, the crossbeam can be designed to be movable. This embodiment is advantageous, for example, in order to be able to achieve a maximum degree of automation, since the lifting unit can act as a feed unit as well as a stacking device. For example, after a first bale has been deposited in the operating space of the lifting unit, e.g. by means of an industrial truck, a second bale, also deposited by an industrial truck, can be lifted by the lifting unit and deposited on the first bale, which can contribute to improved stability of a bale stack. In response to a request signal, the lifting unit can advantageously feed a bale to a shredding device.In conjunction with an advantageous detection device, the lifting unit can individually detect, lift, and feed a bale. This can promote high utilization of the lifting unit, which can also, in principle, increase the utilization of a shredding device.

[0030] Advantageously, the traverse can span the conveyor unit and be designed to be movable longitudinally axially to the conveyor line of the conveyor unit. For improved stacking quality, for example, the bales loaded onto the loading station by an industrial truck can be fed to the conveyor unit by a lifting unit and optimally stacked on the support surface. In response to a request signal, the lifting unit can lift a bale from the support surface and feed it to a shredding device. As before, a detection device for individual bale handling can be economically advantageous for increasing the utilization of the lifting unit or the shredding device.The conveying of a bale can speed up handling, as the lifting unit does not have to travel the entire way to a resting place of a bale on the support surface, but the bale is conveyed towards the lifting unit, so that the design of the action spaces can be coordinated.

[0031] If it is intended to span several conveyor units, the lifting unit on the traverse can be provided with the ability to move in the span direction, i.e. essentially transversely to the orientation of a conveyor unit.

[0032] To increase occupational safety, particularly when bales are stacked in multiple layers on the support surface, a safety element can be provided, for example in the form of a side barrier, which stabilizes the lying bales or the bales stacked on top of each other on the support surface so that they cannot fall off. Safety elements can preferably be arranged on both sides of the conveyor unit, essentially along the conveyor line up to the mouth of the conveyor line in the operating space of the lifting unit. Furthermore, safety elements can be provided that limit human access to the loading device, for example in the form of access barriers or the like, or safety elements, for example in the form of light barriers or the like, which force the bale machine to stop operating as soon as people enter certain risk areas, in particular the operating space of the lifting unit.

[0033] Particularly for more flexible use of the bale handler, the bale handler can be provided with a bale lock with a loading platform. The loading platform is preferably located adjacent to the lifting unit, i.e., within its operating space, so that the lifting unit can, if necessary, transfer a bale that has been placed on the loading platform by an industrial truck and is to be transferred into a shredding device for special bale treatment. An infeed can be provided, for example, to enable the production of a defined material mixture.

[0034] In connection with special bale treatment, the detection device can be particularly advantageous in order to be able to identify certain bales on one of several conveyor units and handle them accordingly.

[0035] Advantageously, the support surface can be designed as a sliding or moving floor, for example, in the form of a truck trailer with a sliding floor as a mobile conveyor unit. Preferably, the truck trailer can be connected to the lifting unit for signal transmission, so that the sliding floor can be activated when a request signal is generated, for example, when a shredding device has free capacity, or as soon as the lifting unit has removed a bale from the truck trailer. In particular, unmanned operation is economically advantageous and reduces the risk of accidents.

[0036] The invention further proposes a method for handling materials pressed into bales and intended for comminution. According to the proposal, one or more bales are temporarily stored in the operating space of the lifting unit as a buffer, in particular in order to be able to feed a comminution device for a period of time without personnel, for example overnight or on holidays. By means of the lifting unit, the bale is then lifted or lowered from a first level, namely the level of the support surface, to a second level arranged above the first, and fed to a comminution device. The feeding is controlled by a bale being fed by the lifting unit as soon as the comminution of a previously fed bale has progressed accordingly and a new feed is possible to increase the utilization of the comminution device. Finally, the bale or the materials pressed into bales are comminuted.

[0037] In one embodiment, it can be provided that the bale is first transported from a storage location to the action area by means of an industrial truck.

[0038] In a further embodiment of the method, a bale can first be placed on a conveyor unit and then conveyed to a lifting unit until the bale reaches the action space of the lifting unit so that the unit can lift the bale and feed it to a shredding device. Instead of a conveyor, a movable lifting unit can be provided, essentially along the longitudinal extent of the conveyor line, so that the action space is increased. The option of conveying a bale by means of a conveyor unit firstly increases the buffer storage capacity and secondly creates the option of optimising feeding by regulating the conveying to match the feed depending on the utilization of the shredding device.

[0039] Advantageously, a release of the bale can be provided, for example after the bale has been lifted and before it is fed to a shredding device, in order to be able to feed the materials to the shredding device more effectively and to be able to separately remove binding agents which hold the bale together in a pressed state and which could possibly unnecessarily contaminate the materials, in particular in the sense of sorting purity.

[0040] In one embodiment, a binder remover can be arranged in such a way that bales are loosened before lifting, and the loosened materials are transferred into a bale trough of the lifting unit, with the lifting unit advantageously feeding several shredding devices. The bale trough allows for optimized feeding of the loosened materials, resulting in high utilization of the shredding devices.

[0041] Advantageously, the loosened bale can be fed to a shredding device in a metered manner, such that materials are continuously fed into a shredding device, whereby as large a quantity of material as possible is shredded per unit of time and at the same time as little drive energy as possible is consumed by the shredding device.

[0042] As a detection system, the bales can be detected, particularly characteristics such as the type of material, weight, degree of soiling, moisture content, or the like, preferably after a bale has been lowered or raised. The described features of the bale dispenser, particularly the portal or bridge solution, each have their own independent inventive significance. They can be used together in any combination or individually and independently of one another.

[0043] An embodiment of the invention is explained in more detail below with reference to schematic representations, whereby individual features or a combination of features of the illustrated embodiment can also be implemented independently of the remaining design of the embodiment in a proposed method.

[0044] Fig. 1 shows an exemplary process flow in a schematic representation.

[0045] In the present embodiment of a method 1, several bales are temporarily stored 2 on a support surface. To increase buffer capacity, the support surface is designed to be enlarged so that it is partially located outside the operating area of ​​the lifting unit. By means of a conveyor unit, the bales are conveyed along a conveyor path resting on the support surface toward the lifting unit 7 until the bales reach the operating area of ​​the lifting unit.

[0046] A bale located within the lifting area of ​​the lifting unit is lifted 3 by the support surface and fed 4 to a shredding device. In the shredding device, the bale is shredded 5 as required so that the shredded material can be fed to further processing steps. In order to determine the shredding progress, the current drive power of the shredding device is determined. As soon as a certain threshold value is reached, exceeded, or undershot, a request signal is generated. The threshold value is to be aligned with the load capacity of the shredding device, with the result that downtimes can be maximized in an economically advantageous manner. For largely automated operation, the request signal is processed by a control device which regulates the bale feed 6, such that a bale is fed 4 as soon as a request signal is detected.

[0047] Furthermore, in the present embodiment, the bales each have a storage medium. Information about the type of material and the degree of contamination of the materials is stored. The stored information is captured 8 by a reading element, namely while the bales are temporarily stored or buffered 2 on the support surface of the conveyor unit and / or while the lifting unit lifts the respective bale from the support surface 3. Given that several bales are regularly shredded 5 one after the other and the shredded materials form a common mixture or batch, the information capture 8 serves, among other things, to ensure the traceability of the shredded materials, ensuring that conclusions can be drawn at any time, for example, regarding the composition of a batch of shredded materials.

[0048] In a particularly advantageous embodiment (not shown), both the bale conveying 7 and the bale lifting 3 are also controlled. This holistic control of coordinated action areas allows the bale machine to be operated particularly economically, and minimizes safety risks for personnel. Reference symbols:
