Definitions

  • the invention relates to a device for conveying a row of loose objects in a vertical direction positioned one behind the other.
  • Products are produced and processed in batches in many branches of industry.
  • the products have to be conveyed, usually in a vertical direction, between the various processing stages.
  • the products to be conveyed are usually fed having a mutual spatial relationship, such as a stack or row, and it is important for the subsequent processing stage that this mutual spatial relationship is maintained.
  • a device to convey a row of objects in a vertical direction positioned one behind the other, whereby the row of loose objects is maintained after being conveyed.
  • US-B-6434 912 describes a device for conveying a row of loose objects in a vertical direction positioned one behind the other and extending in a substantially horizontal direction, whereby the device comprises two elongated support elements extending in a substantially horizontal direction to support the loose objects, it being possible to move both support elements in conjunction with a downward directional component between an upper position, in which they support the loose objects and a lower position in which the support elements have moved apart from each other, whereby the support elements are each connected in a rotatable fashion to a rotation axis extending parallel to the support elements and an elongated carrier element positioned below the middle of the support elements and extending in the longitudinal direction of the support elements, to support the loose objects if the support elements have moved apart from each other.
  • the object of the invention is to provide such a device with which the objects can be conveyed over a greater height. This object is achieved in that when the widest part of the loose objects is located at the joining line between the rotation axes, the distance between the support elements on the joining plane between the rotation axes is greater than the width of the loose objects.
  • the support elements are symmetrical to each other.
  • the objects to be displaced are in most cases symmetrical, so that if the support elements are symmetrically shaped, it is possible to avoid displacement as a result of asymmetry, which could disrupt the support process.
  • a subsequent embodiment provides for the measure of the support elements having a concave and inward-curving shape and that the shortest distance between the rotation axis and the support elements is greater than the arc radius of the curved shape of the support elements.
  • This makes it possible to combine an as long as possible vertical path with an as short as possible turning radius, thus restricting the available space as much as possible.
  • the arc radius of the concave support elements is in relation to the shape of the objects to be conveyed. In the case of circular objects, such as most can lids, the arc radius of the concave support elements is preferably slightly larger than that of the objects. It should furthermore be noted that the concave shape makes it possible to support the objects over a large part of the path.
  • the rotation axes in the uppermost position of the support elements are preferably situated below the lowest point of the objects.
  • a simple manner is thus achieved for covering a long vertical path, whereby - even if the distance between the axes and the support elements is relatively short - the objects to be displaced are sufficiently supported.
  • this measure prevents the objects being conveyed from jamming between the support elements during the conveying operation, in particular in combination with the measure of the curved shape of the support elements.
  • Each support element is preferably connected to the rotation axis by means of a connecting structure, whereby a cavity accessible from below is incorporated between the support elements and Uie connecting structure. Space is created for other structures in particular as a result of the low position of the support elements. In many cases, this measure is otherwise implemented by only connecting the upper edge of each of the support elements to the rotation axis. This is particularly, but not exclusively important if the objects to be displaced are subjected to a space-demanding processing stage while they are being vertically conveyed.
  • the support elements are shaped such that the distance between the support elements is greater than or equal to 0 while the support elements are moving. This measure makes it possible for the support elements to execute a directional component toward each other when covering their arched distance, without the support elements jamming against the loose objects.
  • the path can comprise a large part of the total arc around the rotation axis, thus giving greater freedom for the dimensioning of the device.
  • the support elements it is also possible for the support elements to overlap each other. This measure prevents the support elements from jamming, while making it possible for the objects to be supported over an even greater vertical path; this measure indeed allows a greater mutual movement between the support elements jamming and the objects being released in the horizontal direction, during which time the objects are supported. This greater freedom in the horizontal direction can be used to increase the path in the vertical direction.
  • the device is dimensioned for packaging stacks of can lids.
  • the invention relates to the objects, such as can lids, maintaining their mutual positional relationship while they are being moved along a path in a downward direction. In other words, they must not get mixed up. This can be achieved by supporting the objects along their entire downward path.
  • the object it is also possible to only support the objects for a part of their path; either the objects cover the last part of the path without support, or they drop.
  • the extent of this path depends on the shape of the objects and other variables. It became apparent to the inventor that with can lids, one of the most important applications of this invention, in particular circular can lids, the part of the path to be freely covered is equal to half the diameter of the can lids. With this dimensioning, it turns out that the mutual spatial relationship between the can lids continues to be maintained. For the rest, this dimensioning provides sufficient freedom to execute the return movement of the support elements.
  • an application of the invention now provided comprises the packaging of loose objects.
  • an appropriate embodiment provides for the measure of providing stretching means to stretch a strip of flexible material between support elements in their first position and the carrier element, whereby the stretching means do not impinge on the path of the support elements.
  • a strip of flexible material in which loose objects have to be packaged is folded downward. In this way the objects are already to a large extent enveloped in the flexible material.
  • the support elements are then moved upward again, so that the objects are wrapped freely in the strip of flexible material.
  • clamping and melting means are moved toward each other above the loose objects, after which the packaged row of objects can be removed.
  • the pieces of film can also be bonded by means of adhesive instead of via melting.
  • a new strip of packaging material obviously has to be stretched out before the procedure can be repeated.
  • Another preferred embodiment provides for the measure of providing the carrier element with a push element for pushing the objects upward and providing a control unit for coordinating the movements of the push member and the support elements before the objects are pushed from the carrier element up to Hie support elements in their first position.
  • This embodiment makes it possible for the objects to move in a downward direction in a controlled manner, as well as in Hie opposite direction. In this respect it is important for the carrier element to push the objects upward at least as far as they can be supported by the support elements.
  • the possibility referred to above for the loose objects to be conveyed in two directions means that it is possible to store the objects in the carrier, to displace this carrier and to move the objects upward again when so required.
  • a specific embodiment provides for the measure of the device comprising more than one carrier element and the carrier elements being positioned in a carrier that can be displaced at least in a horizontal direction.
  • the measure referred to above can be implemented by positioning the carrier elements on a continuous belt, whereby the continuous belt can be moved in a direction transverse to the longitudinal direction of the support elements.

  • shrinking means for shrinking the envelope applied around the stack of can lids. This means that it is possible to shrink the film applied around the stack of can lids while they are being conveyed downward, to create a manageable packaging. It is then possible to guide the stack of can lids provided with a loose envelope using an element with a number of nozzles directed inward. These nozzles are arranged for directing a jet of hot gas onto the stack of can lids so that the envelope shrinks around the stack of can lids. It is then attractive to arrange the nozzles such that the end surfaces are sprayed with a hot gas.
  • the shrinking means preferably comprise a means for conveying, in a substantially longitudinal direction, a stack of can lids and a row of outlet openings for a hot gas directed toward the path of the stack of can lids.

Abstract

L'invention concerne un dispositif destiné à l'acheminement d'une rangée d'objets en vrac dans une direction verticale, les uns derrière les autres. Ce dispositif comprend deux éléments de support qui s'étendent dans la même direction que la rangée d'objets, lesdits éléments de support pouvant être déplacés conjointement avec un composant directionnel orienté vers le bas, entre une première position, dans laquelle les éléments de support supportent les objets en vrac, et une seconde position, dans laquelle les éléments de support sont écartés l'un par rapport à l'autre. Le dispositif comprend également un élément transporteur situé sous le milieu des éléments de support, destiné à transporter les objets en vrac lorsque les éléments de support sont écartés l'un par rapport à l'autre. Les éléments de support sont conçus pour supporter les objets lorsqu'ils sont acheminés vers le bas, sur une grande partie du trajet vers l'élément transporteur. Du fait que les éléments de support fournissent un support suffisant pour les objets en vrac sur toute la longueur du trajet, le rapport spatial mutuel, tel que celui de la rangée, est maintenu durant l'opération d'acheminement.
