    Roller carrier
    The present invention relates to a rotatable roller carrier for conveyor systems of the type typically found in connection with cash registers in supermarkets and the like. In particular, the present invention relates to a device which enables rapid release and thereby also rapid removal and installation of an endless conveyor belt provided in the aforementioned conveyor systems.
    According to a first aspect, a roller carrier is provided to support a roller which forms part of a belt conveyor provided with an endless belt. The roller carrier comprises a support arm having a first end and a second end, the first end being arranged to be rotatably connected to a portion of a belt conveyor. The other end is designed to receive a carrier for a roller provided for controlling an endless conveyor belt, whereby the carrier arm, when rotating about a axis of rotation, allows the roller carried by the carrier arm to occupy at least a first and second positions in which the roller in the first position is arranged such that an endless belt controlled by the roller is extinguished and in which an endless belt controlled by the roller is tensioned in the second configuration. The device further comprises a pawl designed to lock the support arm in the second position after the support arm has been rotated from the first position to the second position.
    Background
    Conveyors of the type incorporating an endless conveyor belt are used in various applications, such as in the case of cash registers in supermarkets, in production lines and in facilities for handling products or cargo, etc.
    2 DK 2010 00150 U4
    Conveyor systems including conveyor belts need regular service and maintenance and often also - either for obvious reasons or for wear - replacement, which - depending on the type and application of the conveyor system in question - can be a cumbersome task requiring both tools and skills. person performing the operation in question.
    In addition, conveyor systems adapted to handle food need regular cleaning, which may also require either complete removal or slackening of the conveyor belt, which is also considered a cumbersome task with reference to the above.
    Endless conveyor belts applied to conveyor systems disposed in connection with cash registers and the like are typically replaced by operating threaded rods or adjusting screws or equivalent designed to support a roller provided for controlling the endless belt. In particular, when replacing a belt, the threaded rods are rotated about its longitudinal axes a significant number of times to move a roller carried by the rods so as to obtain sufficient slacking of the belt, whereby the belt can be removed from the conveyor. After replacing the belt, the rods are operated opposite to the above operation, whereby the belt is finally brought under a predetermined voltage.
    Manufacturers as well as end users and conveyor system maintenance personnel for the delivery of relatively light goods are demanding a solution to obtain fast and easy assembly and / or replacement of endless conveyor belts.
    By providing fast and easy replacement of conveyor belts, the end user can easily use and easily switch between belts of different colors or themes that include themes suitable for eg. seasons such as Christmas or summer, etc. In addition, the end user can display information on the tapes, such as advertising and the like. For these and other reasons not mentioned, a device is required for rapid release and replacement.
    In conveyor systems with endless bands for heavy goods, a system commonly known as "BDL Quick Release", cf.
    http://www.bdldrummotors.com/ and the FIGS. 6 and 7, include carrier iron mounted on the carrier bed. The carriers will pivotally carry snap-on arms designed to receive rollers, drums, or motors provided to drive or control an endless conveyor belt. The arms and thus also the received rollers, drums or motors are pivotable about a axis of rotation, whereby the rollers, drums or motors can take two positions; an open position where the tape is off, and a closed position where the tape is energized. The arms are maintained in the closed position with forces resulting from the tension of the belt when the arms including rollers, motors or drums are forced into a "load over center" position, whereby the tension of the belt helps to keep the arms in their closed position. use the BDL Quick Release system only in the case of heavy goods conveyor systems, the forces exerted by the belt giving the above-mentioned "load over center" effect must be significant to ensure that the rotatably supported roller is maintained in its closed position. In addition, underlying rollers are provided which serve to establish a resultant force on the rollers oriented such that the direction of the resultant force intersects a plane defined by the conveying direction of the conveyors, thereby further increasing the "load over the center" effect. after the rollers have been rotated about the axis of rotation.
    In US 4561538, a roller carrier comprising two support members is proposed for supporting a roller which is part of a belt conveyor with an endless belt. The roller shaft is mounted in a displaceable bearing housing located at one end of the support arm, while a mounting bush, at the other end of the support arm, is connected perpendicular to the shaft via a hole in the belt conveyor frame. The two supporting arms have a common axis of rotation, corresponding to the axis of rotation, oriented perpendicular to the direction of conveyance of the belt.
    During belt replacement, the belt can be extinguished by rotating the support arms about a axis of rotation and lifting the roller until the support arm is perpendicular to the belt. When the belt is to be re-tensioned, the support arms are rotated back to a horizontal position, parallel to the conveying direction of the belt. The roller and the position of the support arm are held by a spring-loaded pawl in engagement with one of two recesses on the pivot shaft. The pile is mounted in a bracket inside the conveyor frame and the recesses on the shaft are placed with approx. 90 degree distance corresponding to the vertical and roll respectively. horizontal position.
    US4561538 further suggests that there may be pallets mounted on one or both walls.
    The embodiment of the present invention differs from the device of US 4561538 in that the pile is a bevelled pin provided with a groove or cavity for receiving part of the support arm in its second position.
    US 3592071 A proposes a belt conveyor tracking system including a pivotally mounted roller. The system is primarily used in paper processing apparatus, such as printers and copiers, etc. According to the document, a roller shaft is mounted in a set of support arms positioned parallel to the conveying direction of the belt. The arms are rotated about a 5DK 2010 00150 U4 floating support, whereby another arm, arranged transversely to the direction of advance, is secured to the aforementioned arms by means of bearings. The cross arm is itself pivotally mounted on a support plate, whereby a axis of rotation of the cross arm lies in a plane dividing the angle of the belt running on each side of the roller. If the conveyor belt during movement is to move away from a desired path, a mechanical feedback force representative of fault detection as detected by rollers gripping the edge of the belt will be transmitted to the transverse arm by a mechanical coupling whereby the motion is transmitted to the former arms which will rotate about an axis normal to a plane defined by the direction of advance. The transverse arm moves against the action of a bias spring, and the rotary action of the transverse arm will cause the belt to center around its optimum operating path.
    Brief description of the production
    With the present invention, it is intended to provide a roller carrier to support a role which forms part of a belt conveyor system, the manufacture addressing and resolving the disadvantages and deficiencies of the known conveyor systems mentioned above.

    Detailed description with reference to the figures
    The teachings and steps necessary for the manufacture of a conveyor system which are considered to be banal or equivalent to prior art conveyor systems are omitted from the following preparation to limit the scope of this specification.
    Figure 1 shows in perspective view a belt conveyor incorporating a roller carrier according to the present invention. The conveyor is in the illustrated image in a ready state, ie. in a condition where the belt 90 is brought under tension by rollers 60 and 61.
    The rollers 60 and 61 are connected to a conveyor bed or frame 40. The conveyor bed or frame 40 may be constructed for the purpose of fitting into or grasping the cash registers typically found in supermarkets and the like.
    As will be apparent from the figure, the roller 60 is supported by arms 10 having a longitudinal axis 15. The supporting arms 10 are pivotally connected to the conveyor bed or frame 40, whereby the roller 60 is allowed to occupy at least two different angular positions relative to a axis of rotation 70 of the arms 10; a first position wherein the arms 10 are oriented such that an angle is formed relative to a plane defined by a direction of advance; and another position where the arm 10 is oriented substantially in a conveying direction of the belt conveyor.
    The axis of rotation 70 of the arms 10 can be established e.g. by one or more through shafts or shafts or, as equivalent alternatives, posts or the like arranged on each side of the conveyor. In addition, the arms 10 may be pivotally connected to the conveyor or conveyor bed through bushings or bearings or equivalent.
    The arms 10, which will typically be provided on the device of the present invention as two opposing arms, are disposed on either side of the belt, may constitute threaded rods as shown in the figures, castings (not shown) or processed pieces of plate (not shown). or similar.
    In the embodiment shown, the support 50 for the roller 60 is connected to the arms 10 by means of threads provided in the support 50 for the roller 60 respectively on the arm 10, and the support 50 is thereby simply connected to the arm 10 by a screw connection. In addition, the screw connection can also be used to obtain an appropriate tension on the belt 90 by moving the support 50 in the direction of or away from the axis of rotation 70 of the arm 10 after the roller 60 has taken the second position (Figures 1-4).
    One or both of the rollers 60 and 61 may be rollers with built-in drive motors.
    As will be seen from FIG. 2, the endless belt conveyor system having the advantage of the roller carrier according to the present invention may constitute a conveyor system incorporating only two rollers, since it is not required to have a "load-over-center" effect for holding the roller 60 in the second position.
    10 10GB 2010 00150 U4 In fig. 3 and 4, other views of the conveyor system of FIG. 1 and 2.
    In FIG. 5 shows an endless belt conveyor system according to Figures 1,2, 3 and 4, but here the belt conveyor system is shown in a position where the roller 60 is placed in a first position which leaves the belt 90 off.
    After placing the roller 60 in the first position, the slack belt 90 can be easily replaced with a second belt, after which the roller 60 can be placed in the second position by rotation about the axis 70 of the arms 10, thereby releasing the belt 90 under tension.
    A pal 100, which is best shown in FIG. 1, 3, 4 and 5 are arranged to catch and hold the arms 10 after the roller 60 and thereby also the arms 10 have been moved from the first position (Fig. 5) to the second position (Figs. 1, 2, 3 and 4). Pile 100 may comprise a beveled pin or pin or equivalent provided with a groove or cavity 95 arranged to receive a portion of the arm 10 after the arm has been rotated about the axis 70 to the second position. Although the pile 100 is shown as a pallet designed to receive and hold the arm 10, this should in no way be considered as essential to the present invention. The pile 100 may as well take on another shape, such as a pointed stub (not shown) designed for engaging with holes not shown or the like provided in the arms 10.
    The pile 100 may constitute a spring loaded pawl where the load applied by the spring not shown on the pile 100 can be selected to be such that the pile 100 can be released, ie. is partially moved into frame 40 simply by force applied by the finger of an operator. In addition, the pile 100 may be provided with means not shown to facilitate hand operation such as a protrusion or a circular ring or equivalent.
    11 DK 2010 00150 U4
    In order to retain the roller 60 in the second position, the pile 100 may be provided on one or both sides of the conveyor belt 90 or even - depending on the embodiment chosen - at one or both ends of the conveyor system, i.e. in connection with one or both rollers 60, 61 or rollers provided with drive motors, which means that both rollers 60, 61 can be pivotally connected to the conveyor bed or frame by means of the device of the present invention.
    FIG. 6 and 7 show a known heavy goods belt conveyor designed for rapid release of belt 101, the conveyor 6 of FIG. 6 is shown in a configuration where the endless belt 101 is under tension and the conveyor of FIG. 7 is shown in a configuration where the endless band 101 is stretched.
    The known conveyor comprises arms 110 pivotally connected to the conveyor frame or bearing 120 via removable holders 115, and, as will be apparent from the figures, the arms 110 are pivotable about a axis of rotation 125 to either slacken or bring the endless belt 101 under tension.
    The known conveyor is provided with underlying rollers 135 which serve the purpose of establishing a resultant force 130 on the rollers 105, from the tension established in the belt 101 which is oriented such that the direction of the resultant force 130 crosses a plane defined by the conveying direction of the conveyor, thereby creating a "load-over-center" effect when the rollers have been rotated about the axis of rotation 120, which effect causes the rollers 105 including the irons 110 to remain in a position where the belt 101 is brought under tension.
