BALER COMPRISING A SAFETY SYSTEM

The invention relates to a baler comprising a safety system.

BACKGROUND

The use of cardboard boxes, plastic bags, plastic wrapping and the like for packaging, storage and transporting of e.g. food products and staple goods is widely known in the industry. After use of the storage and packaging materials, they are normally disposed or recycled. For an easy handling of these waste products, balers are commonly used to create compacted bales by pressing all extra air inside e.g. the cardboard out. Balers normally comprise a compaction compartment with a press plate that compacts the waste product placed therein. The waste product is placed in the compaction compartment through a door located at an upper part of the baler. After closing this door, the press plate may be activated, whereby it compacts the waste product by pressing the product from one end of the compaction compartment towards an opposite end of the compaction compartment. The compacted bale of waste material can subsequently be subtracted from a second door placed at a lower part of the baler.

The upper door for depositing the waste into the baler can be opened in different ways, e.g. manually or automatically. Normally, the door would be open the majority of the time, such that waste product may be placed in the compartment. When the waste product is to be compacted, the door must be closed. Upon closing the door or if the mechanism that normally provides that the door is open fails, there is a risk that the user can get his/hers hand caught by the door, if e.g. he/she tries to put in or remove extra waste as the door is closing. As there is an increasing focus on safety at working places, these commonly used upper doors can be problematic. One way to solve this problem in the prior art has been to provide a lock which then needs to be released or unlocked prior to closing the door. However, such locks may be cumbersome for the user to operate. Furthermore, the use of such a lock may not prevent all accidents, such as if the user tries to put in or remove extra waste as the door is closing.

Thus, it remains a problem to provide a safety system for a baler.

SUMMARY

Disclosed herein is a baler for making bales of a waste material, such as e.g. cardboard or plastic, by compacting the waste material. The baler comprises a compaction compartment for containing the waste to be compacted. The baler comprises a door being configured for providing access to the compaction compartment. The baler comprises door movement means configured for moving the door. The baler comprises a frame part configured for surrounding at least part of the door. The frame part comprises at least one receiving means. The baler comprises a safety system. The safety system comprises a safety arm configured to be connected to the door movement means. The safety system comprises latching means connected to the safety arm and configured for moving between a first position allowing the door to move and a second position preventing the door from moving by engaging into the at least one receiving means. The safety system comprises equilibrium means connected to the safety arm and configured for moving the latching means from the first position to the second position when the door movement means is interrupted.

By the above, is thereby obtained a baler comprising a safety system, which can prevent the door from closing or from closing completely when the door movement means is interrupted. Hence, accidents involving a user getting his/her hand caught by the door due to malfunctions of the baler may be avoided. Thus, it is an advantage that a reliable and robust safety system is provided that may reduce or eliminate accidents when operating a baler. Furthermore, it is an advantage that the safety system as disclosed eliminates the need for a lock and that the user is therefore not required to release the lock prior to closing of the door. Furthermore, it is an advantage that a versatile safety system is provided that may be adapted to specific requirements of the baler or of the operation of the baler.

The baler comprises a compaction compartment for containing the waste to be compacted. The baler comprises a door being configured for providing access to the compaction compartment. The door may be configured for opening and closing. The door may be configured for moving vertically, i.e. up and/or down, such as predominantly vertically, to provide access to the compaction compartment. The door may be configured for also moving horizontally at the beginning or end of opening and/or closing of the door, such that the door moves in an L-shaped curve when opening and closing when viewed from the side. The waste may be e.g. cardboard or plastic. The waste may be placed in the compaction compartment through or via the door. The door may be located at an upper part of the baler.

The baler comprises door movement means configured for moving the door, such as for moving the door when it opens and/or closes. The door movement means may be configured for moving the door upwards and downwards in a vertical, such as predominantly vertical, direction. The door movement means may be connected to the door. The door movement means may be connected to a gear, toothed gears, a gear wheel, a sprocket, a sprocket-wheel or a chainwheel provided in/on or at the baler. The door movement means may be connected to a wire winder provided in/on or at the baler. The door movement means may be connected to a weight, such as a counterweight, provided in/on or at the baler. The door movement means may provide power transfer which causes movement of the door, such as a translatory movement of the door in the vertical direction, i.e. up and/or down or upwards and/or downwards.

The baler comprises a frame part configured for surrounding at least part of the door and comprising at least one receiving means. The frame part may be configured for enclosing or surrounding or supporting at least part of the door. The frame part may comprise two or more bars, rails or studs. The receiving means may be a cavity or an opening in the frame part. Alternatively, or additionally, the receiving means may be a protrusion protruding or projecting from the frame part. Alternatively, or additionally, the receiving means may be a plate or a pin, the plate or pin may be arranged in an opening of the frame part or the plate or pin may protrude or project from the frame part.

The baler comprises a safety system. The safety system comprises a safety arm configured to be connected to the door movement means. The safety system comprises latching means, such as connection means or engagement means or fastening means or securing means or anchoring means. The latching means is connected to the safety arm. The latching means is configured for moving between a first position allowing the door to move and a second position preventing the door from moving by engaging into or onto the at least one receiving means. Thus, in other words, the latching means may be configured for being received or caught by one of the at least one receiving means in the second position. Correspondingly, the at least one receiving means may be configured for receiving or catching the latching means in the second position.

The safety system comprises equilibrium means connected to the safety arm and configured for moving the latching means from the first position to the second position when the door movement means is interrupted. The door movement means may be interrupted if the door movement means is broken, torn or discontinued.

In one or more embodiments, the safety arm is connected to the door movement means when the latching means is in the first position. In one or more embodiments, the safety arm is not connected to the door movement means when the latching means is in the second position.

In one or more embodiments, a first force is acting on the safety arm due to the safety arm being connected to the door movement means and a second force is acting on the safety arm due to the equilibrium means being connected to the safety arm. Thus, the first force may be acting on the safety arm when the latching means is in the first position. In one or more embodiment, the first force is balanced by the second force, such as the first and second force is in equilibrium, when the latching means is in the first position. This balance or equilibrium may be broken or disrupted when the door movement means is interrupted, because the first force may then no longer be acting on the safety arm.

In one or more embodiments, the safety arm is configured to be pivotable around a point along an axis in which the safety arm extends. Thus, the safety arm may be pivotable around said point when the latching means is moving from the first position to the second position.

Alternatively, the latching means may be configured for moving between the first position and the second position in a translatory motion. In other words, the latching means may be configured for moving between the first position and the second position without any change in an orientation of the safety arm. Additionally, the latching means may be configured for moving between the first position and the second position in a substantially horizontal manner or in a substantially horizontal plane. In this embodiment, the safety arm may be configured to be connected to the door movement means via the latching means.

In one or more embodiments, the safety system is provided on the door, such as provided in/at the door. The safety system may be provided at a first end or side of the door. The safety system may be a first safety system. The baler may comprise a second safety system. The second safety system may comprise identical features to that of the first safety system, and the second safety system may be configured to be provided at a second end or side of the door, the second end or side being opposite to the first end or side of the door.

In one or more embodiments, the door movement means is provided within or in the frame part, such as least partly within or in the frame part.

In one or more embodiments, the frame part comprises two or more receiving means, the two or more receiving means provided at different heights in the frame part. The height may be defined as starting from one end, such as a button, of the frame part, or may be defined as starting from the ground. Hereby, the door may be prevented from closing or from closing completely at different heights or positions.

In one or more embodiments, the door movement means is a chain, a wire, a rope, a belt, such as a toothed belt, timing belt or gear belt, or a strap.

In one or more embodiments, the latching means is a catch, a protrusion, a latch, a fork, a pin or a hook.

In one or more embodiments, the equilibrium means is a counterweight, a switch, a spring such as a mechanical spring, a gas spring compression spring, or a pneumatic system or device.

In one or more embodiments, the safety arm is configured to be connected to the door movement means via a hook, a ring, a bolt, a gear wheel, a fork or a pin. In one or more embodiments, the safety arm is configured to be connected to the door movement means via the latching means.

In one or more embodiments, the door is configured to be closed manually by a user. Thus, the user may move, close or press or pull the door downwards to manually close the door. Alternatively, the door is configured to close automatically.

In one or more embodiments, the baler comprises a press plate or a ram configured for compacting the waste. The press plate may be a hydraulic press plate.

In one or more embodiments, the baler is a vertical baler. Thus, the press plate may move vertically inside the compression compartment, thereby compacting the waste vertically by pressing down on the waste.

In a preferred embodiment, the baler comprises, a compaction compartment for containing the waste to be compacted, a door being configured for providing access to the compaction compartment, a chain configured for moving the door, a frame part configured for surrounding at least part of the door and comprising at least one cavity and a safety system. In the preferred embodiment, the safety system comprises a safety arm configured to be connected to the chain, a catch connected to the safety arm and configured for moving between a first position allowing the door to move and a second position preventing the door from moving by engaging into the at least one cavity, and a spring connected to the safety arm and configured for moving the catch from the first position to the second position when the chain is interrupted.

Additionally, FIG. 5a-c shows that the latching means 216 is configured for moving between the first position 218 and the second position 220 in a substantially horizontal manner or in a substantially horizontal plane.

Exemplary examples will now be described more fully hereinafter with reference to the accompanying drawings. In this regard, the present examples may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the examples are merely described below, by referring to the figures, to explain aspects. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

The spatially relative terms “lower” or “bottom” and “upper” or “top”, “below”, “beneath”, “less”, “above”, and the like, may be used herein for ease of description to describe the relationship between one element or component and another element or component as illustrated in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the drawings. For example, in the case where a device illustrated in the drawings is turned over, elements described as being on the “lower” side of other elements, or “below” or “beneath” another element would then be oriented on “upper” sides of the other elements, or “above” another element. Accordingly, the illustrative term “below” or “beneath” may include both the “lower” and “upper” orientation positions, depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below, and thus the spatially relative terms may be interpreted differently depending on the orientations described.

Throughout the specification, when an element is referred to as being “connected” to another element, the element is “directly connected” to the other element, or “electrically connected” to the other element with one or more intervening elements interposed therebetween.

The terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms, including “at least one,” unless the content clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” It will be further understood that the terms “comprises,” “comprising,” “includes” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be understood that, although the terms “first,” “second,” “third,” and the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, “a first element” discussed below could be termed “a second element” or “a third element,” and “a second element” and “a third element” may be termed likewise without departing from the teachings herein.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within +30%, 20%, 10%, 5% of the stated value.

Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this invention pertains. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined in the present specification.

Exemplary examples are described herein with reference to cross section illustrations that are schematic illustrations of idealized examples, wherein like reference numerals refer to like elements throughout the specification. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, examples described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims. Some of the parts which are not associated with the description may not be provided in order to specifically describe exemplary examples of the present disclosure.
