Definitions
- the invention relates to a strap strapping machine for strapping a material to be strapped with a strap, which is preferably a weldable plastic strap, with the ones specified in the preamble of claim 1
- strapping material is understood in connection with the invention to the effect that it comprises different, mostly similar goods, which are combined into an easily manageable bundle with the aid of one or more strapping bands.
- a typical example of a The material to be strapped is a stack of folded box blanks. Since the individual folding box blanks are difficult to handle and transport without strapping, they are bundled into a bundle with the help of strapping.
- a band strapping machine comprises a machine table which carries the material to be strapped during strapping and at least one strapping device.
- Strapping machines are for example from the
- band strapping machines known from the prior art work very reliably and are very efficient. They are mostly arranged at the rear end of a longer process chain. If in this
- Strapping goods that are bundled into a bundle with the help of one or more strapping bands.
- Folding box blanks are fed back into the strapping machine and bundled into a bundle.
- the quality control of the bundles is carried out after the strapping machine. If a bundle is detected there that contains one or more faulty folding box blanks or some other faulty strapping material ("faulty bundle"), it is ejected from the production process in a downstream ejection station and a
- transport devices In order to move the bundles through these stations, transport devices, e.g.
- DE 10 2017 102 854 B3 describes a bundling device with a permanently installed camera below a table, which captures the side edges of bundled goods.
- a similar configuration is also known from DE 10 2008 031 236 A1.
- DE 20 2009 017 138 U1 and DE 10 2014 103 336 Al describe devices for longitudinal strapping with an optical device which, from above, shows the contour of the
- JP 200255512 A also shows a device for strapping with a fixed camera.
- the invention is based on the object of upgrading a strap strapping machine in terms of its functionality and the overall space requirement of a process chain which, among other things, includes the steps of strapping a strapping material into a bundle, quality control and discharge
- faulty bundle includes, more economical
- this object is achieved in a
- a camera in the strap strapping machine is directed at least temporarily at the strapping material, errors in the
- the strapping material is recognized and a bundle recognized as defective, which contains a defective product / a defective folding box blank, is placed directly in the strap
- the strapping machine can be removed from the process chain.
- the camera installed in the strapping machine according to the invention can detect all defects in the products or the folding box blanks that can be visually detected. If an error is detected, the bundle with the defective product /
- Folding box blanks go undetected to the end of the process chain and then to the customer.
- the camera can be moved in a direction which is orthogonal to a plane spanned by the machine table.
- the moving device for example in the form of a
- Ball screw guide it is possible to "scan" the front, back and / or one side of the bundle with the camera and take pictures of the corresponding side of the bundle. By means of a suitable image evaluation, faulty bundles can be identified and the faulty bundles rejected. If the camera can be moved in the direction of a Z axis (ie orthogonal to the XY plane spanned by the machine table), then it is possible to move the camera out of the direction of movement or conveying direction (X axis) of the bundle as soon as the bundle is out the strapping machine is to be conveyed out.
- a Z axis ie orthogonal to the XY plane spanned by the machine table
- the camera can be moved, it is also easily possible to adapt the strap-strapping machine according to the invention to product stacks of different sizes.
- a further increase in flexibility is achieved if the camera can be moved in a second axis (Y-axis), which preferably extends orthogonally to the first movement axis. Then, for example, the entire front or back of a bundle can be captured by the camera, even if it can only take pictures of part of the bundle. It is also possible to target only individual locations on the front, back or sides of the bundle. As a result, the points of the bundle can be targeted and detected by the camera at which errors are to be expected. The rest of the surfaces of the bundle then need not be captured by the camera.
- Y-axis second axis
- the strapping material is a stack of several
- Folding box blanks are arranged along a vertical line (Z-axis).
- the camera is positioned so that it is with a Movement in the direction of the Z-axis traverses all columns of the product stack and takes pictures of the columns.
- Appropriate image analysis can identify gaps that are too wide or too narrow. Whenever a gap is detected that is outside the specified
- the folding box blank is faulty and the faulty bundle is rejected.
- Image recording devices which are known from the prior art can be used.
- CCD sensors, matrix cameras, line scan cameras or laser triangulation sensors are preferably used. It's important, that
- Properties of the bundle in particular parts or the entire surface of the bundle, can be visually detected by the camera.
- the images obtained in this way are evaluated with the aid of an algorithm that can make a statement as to whether they are in the product stack
- the products located are defective or free of defects.
- This evaluation can take place in a control unit of the strap strapping machine or a separate processor. If a faulty bundle has been detected, a signal is output which leads to this bundle being ejected.
- Console arranged on the machine table, at least one press beam arranged movably on the console and
- the console Manipulator for deflecting the strapping tape, with an axis of movement of the manipulator running orthogonally to a plane spanned by the machine table.
- the manipulator is therefore part of the strapping machine.
- the direction of movement of the manipulator and the camera are parallel (in the direction of the Z-axis). It is therefore particularly advantageous if the camera or the device for optical detection of the product stack is directly or
- the machine table and the console are connected to one another by one or more supports, the distances being the
- the material to be strapped is greater than the length of the
- Upstream of the machine table is a feed device for
- Transport of the strapping is arranged on the machine table, and / or that the machine table
- a removal device for removing the Strapping material is arranged downstream from the machine table in the conveying direction. This ensures that the
- the material to be strapped can be conveyed into the machine according to the invention and can also be removed from the strapping machine again after the strapping.
- the device arranged in the process chain directly in front of the strapping machine is responsible for transporting the strapping material into the strapping
- Strapping machine takes over. A separate feed device or a feed device assigned to the strap-strapping machine can then be omitted. The same applies to a device that is located in the process chain behind the strapping machine. If this device can convey the bundle away from the strap strapping machine, a separate device assigned to the strap strapping machine for removal from the strap strapping machine is not required
- a discharge station is integrated in the strapping machine, which a defective bundle in a direction deviating from the normal transport direction (X-axis)
- the product stack is ejected from the process chain directly in the strapping machine by moving it sideways out of the strapping machine.
- the discharge direction (Y-axis) is perpendicular (orthogonal to the conveying direction (X-axis).
- the machine table and the console are connected to one another by one or more supports and the spacing of the supports in the conveying direction (X-axis) of the material to be strapped is greater than the length of the material to be strapped. It is then possible to eject defective strapping material laterally between the supports out of the strapping machine, so that a defective bundle can be ejected without requiring additional space.
- the discharge device can be designed in a simple and very effective variant as a slide which is pneumatically, electromechanically or hydraulically driven. As soon as a defective product stack is recognized, the pusher is activated and pushes the product stack laterally out of the strapping machine between the supports that connect the machine table and the console.
