Description

Winding device for winding binding material

Technical Field

The present invention relates to a winding device for winding binding material (such as strap, wire or rope) from an object that is tethered to the binding material (such as from a bale, such as a bale comprising waste material; or from other wrapped-like objects, such as wrapped chipboard).

Background

The bale is bound, for example, by providing a binding material, such as a strap, wire or rope, around the material to be bound. Bale material may be any material suitable to be bound, such as chemical pulp or waste material, such as RDF, SRF (refuse derived fuel (RDF) or solid recycled fuel/designated recycled fuel (SRF)), and other waste, recyclable material, and industrial material. When the material is bound (such as a waste bale), it is easily stored or transferred to further processing (e.g., to a combustion plant). Typically, it is necessary to open the bound bale and remove the binding material, for example, before further processing of the waste bale, such as before recycling or burning the waste material.

There are solutions for opening the bale, for example for removing the binding material by means of a bale breaker. Bale breakers typically have a cutting device and a gripping mechanism for cutting the binding material, which grips and cuts the binding material and removes it by a pulling movement. Previous bale openers developed by the applicant also included rollers wherein a gripping mechanism pulls the wrapping or binding material between the rollers, after which the rollers are brought against each other and rotated to more efficiently remove the wrapping or binding material from the bale.

Even though previous bale breakers have several advantages, there are some disadvantages associated with them, such as sometimes binding material that may stick to the rollers, which results in inefficient bale breakers. In addition, when the gripping mechanism pulls the wrapping or binding material between the rollers, the baler cannot be used at this time because the baler must wait for the gripping mechanism to return. However, the gripping mechanism may only be returned after the rollers have removed wrapping or binding material from the bale (and possibly also from the gripping mechanism) and when the rollers are opened again so that the gripping mechanism can be returned.

In addition, there are some disadvantages associated with the removed binding material, namely that it is common to stack the binding material only in the next one of the bale openers, where a fuzzy or undefined pile of binding material on the ground in the vicinity of the bale opener is a safety hazard and also messes the available space in the vicinity of the bale opener.

Disclosure of Invention

It is an object of the present invention to mitigate and eliminate the problems associated with the known prior art. In particular, it is an object of the present invention to provide a winding device for winding binding material or a tied bale or other package efficiently, reliably and quickly, and minimizing possible malfunctions, such as eliminating problems associated with binding material sticking to the device. Furthermore, it is an object to speed up the process so that there is no need to wait for the binding material to be removed before the gripping device can return to its position and introduce the next bale to be opened.

The object of the invention is achieved by the features of the independent claims.

The present invention relates to a binding material winding device according to claim 1.

According to an embodiment of the invention, the binding material winding device is configured to catch binding material, such as a strap, wire or rope, from an object tethered to said binding material. The object may be located beside the winding device, such as on a support structure of the bale breaker. The bale breaker or binding material wrapping apparatus may include a gripping mechanism configured to be introduced with the bale to grip the binding material and in turn be removed from the bale with the gripped binding material.

The binding material roll-up device advantageously comprises a guide member arranged to be introduced together with the binding material when the binding material is advantageously removed from the bale by said gripping means. As an example, the guide member may be or may comprise a hook configured to catch or hook the binding material when the binding material is at least partially removed from an object tethered by said binding material. The guide member may also be realized by a rod. Further, the guiding member is configured to guide the binding material towards a winding member of the binding material winding device. It is noted that the binding material may be a plurality of bands, wires or strings, and thus the guiding member is configured to introduce or guide all bands, wires, strings etc. towards the winding member. It is particularly noted that the guide member may be configured to hold the binding material (in particular all individual straps, threads or strings etc.) tight during introduction, and therefore the winding member may effectively wind and remove all binding material under the same actuation, thereby minimizing the possibility that some binding material may be lost. The winding member is advantageously configured to be introduced together with the binding material during actuation of the winding member, thereby winding and removing the binding material via said actuation. As a result, the binding material is wound into a small bundle, such as in the form of a coil, after actuation.

The winding member may comprise a movable portion, such as a sled, comprising a gripper for gripping the binding material when it is introduced by the guide member. The grip may advantageously be achieved by a protruding member or slit in the end of the movable part. As an example, the winding member comprises at least two protruding members, rods or hooks, whereby the guiding member is configured to introduce the binding material between the at least two protruding members, rods or hooks. The protruding member, lever or hook advantageously comprises a common axis of rotation about which the winding member is configured to rotate.

It is noted that when all the binding material (strips, threads or strings etc.) is guided to the winding member, a single bundle, such as a coil, is advantageously formed as a result of the actuation of the winding member.

In addition, the binding material winding device advantageously further comprises a counterpart, whereby the guiding member is advantageously configured to introduce said binding material between the counterpart and the movable part. The winding member is configured to move towards or relative to the counterpart during actuation and advantageously to hold said binding material to be pressed between the movable part and the counterpart. During action, the winding member is also configured to rotate about its axis of rotation and thereby wind the introduced binding material, for example, such that after actuation, the binding material is wound into a bundle in the form of a coil.

It should be noted that the binding material may be removed from the bale in its entirety, e.g. by external means such as a gripping mechanism, before winding, but the winding member may also be used for removing the binding material during the action, and thus during rotation of said winding member.

During actuation, the winding member is configured to press the introduced binding material between the movable portion and the counterpart portion to clamp the binding material. According to an embodiment, the counterpart comprises a recess configured for receiving an end of a movable part (such as a sled) of the winding member. When the end of the movable part may at least partially enter the recess, the binding material may be more tightly captured between the winding member and the counterpart. Further, during actuation, so rotating, the winding member is also configured to wind the binding material and thereby may additionally also remove (optional features) the binding material.

According to an embodiment, the counterpart is configured to move, press the binding material relative to the winding member during winding, thereby guiding the binding material. In addition, during actuation of the winding member, the counterpart is configured to advantageously move backwards in a controlled manner, so as to control the thickness of the wound binding material, and thus the thickness of the coil of wound binding material, in the direction of the rotation axis of the winding member. As more binding material is wound into a coil, the thickness and size of the wound coil tends to increase during winding. In this way, the thickness and overall dimensions of the coil of wound binding material can be kept as small as possible. In addition, a malfunction due to expansion of the wound coil can be minimized.

Further, according to an embodiment, the winding device may comprise at least one guiding device configured to elongate, such as move, around the winding member during actuation, thereby guiding and forcing the binding material against the winding member during winding. In addition, the size of the wound binding material, and thus the diameter of the coil, may be controlled. The guiding means may for example be realized by plates or guiding bars, preferably at least two or three, most advantageously at least four guiding bars. However, other types of suitable guiding means may be applied.

According to an embodiment, the movable portion is configured to move backwards from the counterpart portion after winding the binding material. In addition, the winding device is configured to release the wound binding material, such as a coil. The winding means, advantageously the winding member, may comprise a release member for releasing the coil. The release member may be realized by e.g. a pushing device for pushing the wound binding material away around the winding member, such as around the gripper. In this way, after winding, the winding member and the entire winding device can be kept clean.

It is noted that the winding device may comprise or cooperate with an external gripping mechanism. The gripping mechanism may be configured to be introduced with an object (such as a bale) supported by the support structure to grip the binding material and in turn be removed from the object with the gripped binding material, and in turn be configured to introduce the binding material into the guide member.

According to an embodiment, the guiding member and the winding member are mutually arranged such that the gripping mechanism is able to substantially simultaneously return towards the bale or a support structure for supporting the bale when the winding member is actuated to wind and possibly also remove binding material. For example, the winding member may be located at a much lower height than the gripping mechanism, such that when the guide member grips the binding material and is guided to the winding member located below the height of the gripping mechanism, the gripping mechanism is able and free to move towards the bale or a support structure for supporting the bale. The mutual movement of the guide member, the winding member and/or the gripping means may also be arranged such that said gripping means can be returned. This naturally speeds up the entire process of removing the binding material from the bale, providing significant advantages.

In addition, according to an embodiment, the winding device shown in this document may be provided as a mobile carrier.

The invention has the distinct advantage that it is easier to handle when winding the binding material into small bundles, advantageously single bundles, and in addition the space around the bale breaker and/or winding device can be kept free.

The invention also provides a reliable and fast way to wind the binding material, which allows to minimize possible failures, such as to eliminate problems related to binding material sticking to the device. In addition, the opening of the bale and the removal of the binding material, in particular the winding process, can be accelerated, so that there is no need to wait for the removal of the binding material before the gripping device can be returned into its position and the next bale to be opened is introduced.

In addition, the present invention provides control over the thickness and overall dimensions of the coil of wound binding material and can be kept as small as possible. In addition, the invention can also minimize the fault caused by the expansion of the wound coil.

The exemplary embodiments presented herein should not be construed as limiting the applicability of the appended claims. The verb "to comprise" is used herein as an open limitation that does not exclude the presence of features not yet recited. The features recited in the dependent claims may be freely combined with each other, unless explicitly stated otherwise.

The novel features believed characteristic of the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific exemplary embodiments when read in connection with the accompanying drawings.

Drawings

The invention will be described in more detail below with reference to exemplary embodiments according to the accompanying drawings, in which:

fig. 1 to 5 show the principle of an exemplary device for winding binding material in different operating modes according to an advantageous embodiment of the invention, an

Fig. 6 shows a side view of an exemplary device according to an advantageous embodiment of the invention.

Detailed Description

Fig. 1 to 5 show the principle of an exemplary device 100 for winding binding material 101 in different operating modes according to an advantageous embodiment of the invention. In addition, fig. 6 shows a side view of an exemplary device 100 according to an advantageous embodiment of the invention.

The winding device 100 advantageously operates in conjunction with a gripping mechanism 103, which is typically pushed into an object, such as a bale (not shown), so that it can grip the binding material 101. When the gripping mechanism 103 catches the binding material 101 from the bale (or other object), the gripping mechanism 103 is moved 114 away from the bale along with the gripped binding material 101, as shown in fig. 1. The gripping mechanism 103 may be arranged in connection with an external bale breaker, or alternatively the binding material winding device 100 may comprise said gripping mechanism 103. In addition, according to an embodiment, the binding material winding device 100 may be part of a bale opening device known according to the prior art.

The winding device 100 may further include a guide member 102 for guiding the binding material 101 towards the winding member 104, as shown in fig. 2. The guide member 102 may, for example, grip the binding material 101 after the binding material 101 is removed from the bale, so that thereafter the gripping mechanism 103 passes the guide member 102 with the binding material 101, or introduces the binding material 101 into the guide member 102.

When the guide member 102 catches the binding material 101 and introduces it to the winding member 104, the winding member 104 is actuated, typically rotated. During actuation, the winding device winds and possibly also removes the binding material 101, such that the binding material 101 is advantageously wound into a beamlet 108, such as in the form of a coil 108, as shown in fig. 3 to 5.

The winding member 104 may also include a movable portion 105, such as a sled, that includes a gripper 107 for gripping the binding material 101. As an example, the winding member 104 comprises at least two protruding members, rods or hooks as said grippers 107, as shown in fig. 1, 5 and 6. The protruding member 107 advantageously comprises a common axis of rotation 109 about which the winding member 104 or the movable part is configured to rotate.

The binding material winding device 100 may further include a counterpart 106 so that the guide member 102 can introduce the binding material 101 between the counterpart 106 and the movable portion 105, as shown in fig. 6. The counterpart 106 may also include a recess 110 configured to receive an end of a movable portion 105 (such as a sled) of the winding member 104, as shown in fig. 6.

Counterpart 106 may also move 116 relative to winding member 104 to press binding material 101 and guide binding material 101 during winding, and move 116 backwards to control the thickness of wound binding material 108.

It should be noted that the components of the device, such as in particular the winding member 104, the end of the movable portion 105 and the counterpart 106, may be replaceable parts.

The winding device may additionally comprise guiding means 111. The guiding means 111 is advantageously arranged around the winding member 104 during actuation in order to guide and force the binding material 101 against the winding member 104 during winding. The guide 111 may be fixedly arranged (immovable) or may be configured to actively control the size of the wound binding material 108 during winding, and may thus be movably arranged such that it moves "outwards" 115 as the diameter of the coil increases during winding, as shown in fig. 4.

The guiding means 111 may be arranged in connection with the counterpart 106 such that the guiding means 111 is configured to protrude during winding, thus for example when the movable part 105 and/or the counterpart 106 are moved relative to each other, or the guiding means 111 may be arranged in connection with the movable part 105.

The winding device 100 may also include a release member 112 for releasing the coil, as shown in fig. 5.

The guide member 102 and the winding member 104 (and possibly also the gripping mechanism 103) may be mutually arranged such that said gripping mechanism 103 is able to return 113 towards a new bale or a support structure for supporting a bale (or other object) substantially simultaneously with the winding of the binding material 101 by the winding member 104, as shown in fig. 3-5 (and the processing steps thereof).

The invention has been described above with reference to the aforementioned embodiments and several advantages of the invention have been demonstrated. It is clear that the invention is not only restricted to these embodiments, but comprises all possible embodiments within the spirit and scope of the inventive idea and the appended claims.

The features recited in the dependent claims may be freely combined with each other, unless explicitly stated otherwise.
