Definitions
- the invention relates to a method for controlling the opening mechanism of bags with flat objects.
- Flat objects in particular consignments of different mass and surface, should be stored individually from pockets in containers located underneath, with pockets and containers moving at a differential speed relative to each other. In this case, a speed can also be zero.
- the objects are placed on two edges aligned. This alignment is a prerequisite for a machine further processing, for. As for a sequence sorting and the associated, subsequent manual handling by the postman.
- the document DE 103 05 847 B3 describes a device having an opening mechanism of pockets with flat objects which are gravity fed into underlying containers in a lying position with pockets and containers in relative motion.
- the transmission characteristics are determined and the time at which the opening mechanism of a bag is actuated varies with regard to an optimum stack quality as a function of the determined transmission characteristics.
- the thickness of the shipments As a broadcasting property called the DE 103 05 847 B3 this example, the thickness of the shipments.
- the invention has for its object to provide a method for controlling the opening mechanism of pockets with flat objects for transferring the flat objects by gravity in underlying container in a lying position, with which the alignment of flat objects of different mass and surface is improved on the container wall ,
- the period of time after passing through a reference point fixed to a pocket position is determined experimentally by a reference edge of the container, wherein the opening mechanism depends on the mass of the objects and / or on the previously determined friction coefficient between the bottom pocket wall and the bearing surface of predetermined categories of objects and / or the stack height in the container and the shape according to the type of container used in the relative direction of transport of the container front container wall is opened so that each shipment is stored aligned with this container wall.
- the determined values with the sizes of which they depend are then stored.
- For each item its mass and / or category and / or the current stack height in the containers is determined.
- the stored time is determined for transferring a particular item from the appropriate bag in a particular container of a known type of container based on the respective mass and / or the coefficient of friction and / or the current stack height of the container in question. After the time of passing the reference point by the reference edge of the container in question and the time period determined then the opening mechanism of the bag is opened.
- the measured thicknesses of the previously passed into this container items are summed.
- the articles can also be compressible and measurement errors can add up, it is advantageous, in the case of moving containers, to guide them past at least one measuring station for determining the stack height and the stack height obtained by summation of the measured thicknesses of the articles by the deviating measured value of To correct the measuring station.
- Both the pockets 1 and the containers 5 are inclined in the transport direction of the container 5.9.
- the objects 3 in the pocket 1 are oriented downwards and rest on the lower pocket wall 2.
- At the lower end of each pocket there is an opening mechanism 4, which holds the articles 3 in the closed state and which is opened when the respective article 3 is to enter a certain container 5 by means of gravity.
- the drives of the opening mechanisms 4 are not shown, their implementation and control represents no difficulty for a person skilled in the art.
- the opening time depends on the speed of the container 5, the mass of the objects 3, the friction coefficient between the objects 3 and the lower pocket wall 2, the time when the respective front reference edge of the container 5,9, in this case the upper front reference edge 7, during transport passes the lower part of the respective pocket 1, from the stack height of the already in the respective container 5.9 located stack 8 and the shape of the ih transport direction front container wall, where the objects 3 abut with its front edge from.
- the position of the reference edges 7 of the container 5.9 during transport is determined by the reference edge 7 is detected when it moves past a corresponding sensor and therefore due to the known constant speed can be determined when the reference edge 7, the known position of the lower part the respective bag 1 happens.
- This can also be solved more expensively by attaching a sensor for detecting the reference edge to the lower part of each pocket 1.
- a sensor for detecting the reference edge is attached to the lower part of each pocket 1.
- They dimensions are measured and their mass is determined indirectly by multiplying the volume by an average density. Although this is relatively inaccurate, but due to conducted test series for the control of the opening mechanisms 4 sufficiently accurate enough.
- the respective stack height is obtained from the summation of the thicknesses of the stacked objects 3, this value being corrected after passing through a measuring station for determining the stack height and corresponding deviation.
- the respective period of time after passing through the lower part of the bag 1 by the front reference edge 7 of the container 5.9 determined in test series depending on article mass, coefficient of friction according to the established item category, eg paper and plastic surface, stack height and container shape , in which results in an optimal alignment of the objects 3 on the front in the transport direction of the container wall.
- article mass, coefficient of friction is determined by distinguishing the article category and stack height in the intended bin 5,9, and the stored time found with these values according to the type of bin used is then transferred to the control of the opening mechanism 4 so that the opening mechanism 4 becomes the correct one Time, when the distances S 0 , S 1 , S u or S o are reached, is opened.
- FIG. 3 the memory structure is shown, in which the respective time period T s is stored as a function of the coefficient of friction ⁇ , the volume V, the stack height h and the container type B.
- the pockets 1 can also be designed according to the FIG. 1 and 2 be moved to the left or both.
- the reference point then has a fixed position to a pocket.
- test series before operating mode have given correspondingly satisfactory results with respect to the stack images to control the opening times only in response to individual or only less variable parameters.
