Definitions

  • the present invention relates to a lifting hook for a basket or trolley for storing and / or transporting objects, and more particularly for a basket or trolley having at least one flat vertical face and designed to receive heavy objects in plate installed according to superimposed horizontal plans. This is particularly the case for a trolley on casters used for handling tools for cutting and ejecting a press for cutting a sheet material.
  • Cutting presses of the type to which the object of the invention applies are used in the field of manufacturing folding boxes.
  • Such presses carry out the cutting of a certain number of "poses” or cuts of boxes from a sheet having a large surface area of up to two square meters.
  • the parts of the sheet which do not constitute the blanks are waste which is eliminated in an ejection station placed after the cutting station.
  • a version of cutting press is known which further comprises a separation station between the ejection station and the reception station, this station making it possible to separate each of the boxes of boxes so as to obtain stacks of poses ready to be worked by a folder-gluer machine.
  • the cutting, ejection and separation stations are equipped with suitable tools which, by virtue of the function which they must perform, have a mainly flat horizontal shape with a surface practically identical to that of the leaves to be cut.
  • suitable tools are generally heavy and bulky to handle.
  • the operator uses a handling cart that he brings to each station to load and unload the tools.
  • a carriage is usually based on a rectangular frame mounted at the four corners on casters allowing the carriage to move, this frame can be composed of two lateral beams in the form of H-beams connected at their ends by two U-shaped crosspieces or inverted S.
  • the shape of these beams and crosspieces makes it possible to obtain first slides in which the first tools can be threaded.
  • At the ends of the side members are fixed four uprights held vertical and parallel to each other by side members and tubular cross members located at mid-height. Between these uprights are fixed a second, or even third, pair of slides in the form of angles oriented inwards, and this at predetermined heights usually corresponding to the height of the tools in the ejection station.
  • the object of the present invention is a lifting hook for a basket or trolley whose structure is just necessary and sufficient to simultaneously fulfill the various criteria mentioned below.
  • This hook must first be reliable, that is to say that the dimensions of the constituent parts as well as those of their connection between them must be able to be established so as to exclude any risk of breakage.
  • the shape of the hook must allow free access to at least one vertical face, preferably to two adjacent vertical faces for the free loading and unloading of the tools by direct sliding.
  • the shape and balance of this hook must allow its easy handling in the workshop, as well as its fast attachment and separation from the carriage.
  • the design of this hook must allow for production, maintenance and any modifications at reasonable costs.
  • a lifting hook for a basket or trolley having at least one vertical face including a horizontal crosspiece at mid-height, because it comprises an upper horizontal beam furnished with a lifting ring, a beam of which the first end is connected to at least one vertical support completed at mid-height of a hook ensuring with the crosspiece of the basket or carriage a connection such that it is carried and maintained in alignment with the beam, and completed in its lower end of a shoe bearing against the base of the basket or carriage; and the other end of which is completed with a counterweight ensuring the balance of the hook relative to the lifting ring.
  • the first end of the beam is connected to the center of a horizontal orthogonal bar or arched downward, each end of this bar being extended downwards by a vertical bearing completed at mid-height of a hook oriented upwards and at its lower end of a skate.
  • This double-bearing structure simply ensures the correct alignment of the basket or carriage with the beam.
  • Cross beams at the height of the hooks and pads ensure the correct permanent spacing of the uprights.
  • the beam, the orthogonal bar and the supports have a square or rectangular section, the joints then being in the form of easily weldable lines.
  • the height of the beam is greater than that of the orthogonal bar, so that a notch of section equal to that of the bar can be produced in the end of the beam, the junction by welding can then be carried out. on the upper, vertical front and lower faces of the bar.
  • a carriage 10 intended for the transport and storage of a plurality of flat tools, not illustrated, each having on their lateral edge a groove making it possible to engage them along slides.
  • the lower base of this carriage 10 is formed of a frame comprising two base beams 12 in the form of H-beams held parallel and spaced apart by base cross-members 14 of rectangular section, or in inverted U, or in S overturned.
  • the connection of these beams and crosspieces can be achieved by bolts or by welding.
  • Rollers 16 are attached to the four corners of this chassis the front rollers of which are mounted on free rotation pivots 16 'making it possible to print this carriage turns in one direction as in another.
  • the particular shape of the crosspieces 14 makes it possible to arrange first lower slides 15 while the shape of the base rails 12 forms two pairs of upper and lower slides 13.
  • tubular crossbeams 22 located substantially at mid-height and tubular beams 24 located substantially at three-quarters of the height.
  • tubular crossbeams 22 located substantially at mid-height and tubular beams 24 located substantially at three-quarters of the height.
  • tubular crossbeams 22 located substantially at mid-height and tubular beams 24 located substantially at three-quarters of the height.
  • slides 26 are attached on these uprights. These slides are preferably bolted against the uprights 18 at a predetermined height corresponding to the height of a tool in one of the platen press stations.
  • the lifting hook 50 of the carriage 10 is generally in the form of a vertical gantry 60/70 connected in the middle of the upper bar to a central horizontal beam 52 comprising a lifting ring 54 and ending with a counterweight 56 balancing the gantry with respect to the lifting ring.
  • the gantry consists of two vertical carriers 70 located substantially opposite the uprights 18 of the carriage 10, these carriers being mainly connected together by an upper main horizontal orthogonal bar 60, and the maintenance of which spacing is completed by tubular crosspieces 76.
  • Against the internal face of each bearing 70 are attached, preferably by means of a plurality of bolts, hooks 72 at a height corresponding to that of the front crosspiece 22 of the carriage 10.
  • the anterior underside of each bearing 70 is further completed with a support shoe 74 designed to come to rest against the front base cross member 14 of the carriage 10.
  • the horizontal beam 52, the orthogonal bar 60 and the supports 70 have a rectangular section allowing them to be easily assembled by welds along lines.
  • the height of the beam 52 is greater than that of the orthogonal bar 60 so that a section notch corresponding to the section of this bar 60 is provided at its left end, this end being, if desired, completed horizontal atria 51.
  • the junction between this beam 52 and this bar 60 is produced by welding on three planes: upper plane, anterior vertical plane and lower plane. This type of connection proves to be particularly resistant to a couple of forces which can generate a rotation of the bar 60 on itself inside the notch of the beam 52.
  • the central beam 52 finds itself substantially in a horizontal equilibrium due to the presence of the counterweight 56 balancing the gantry.
  • This lifting hook 50 is then easily manipulated by its cross members 76 to bring the gantry against the front face of the carriage 10 and more particularly, the hooks 72 under the cross member 22, in particular near the uprights 18.
  • the base cross member 14 of the carriage 10 immediately bears against the lower pads 74 thus preventing the front part of this carriage from tilting downwards.
  • the position of the lifting ring 54 on the beam 52 corresponds to the point of passage of the vertical passing through the center of gravity of the carriage 10.
  • the lifting of this carriage 10 by the lifting hook 50 is then balanced manner, that is to say that the beam 52 always remains well in alignment with the side members of this carriage, these beams and side members remaining in a substantially horizontal plane.
  • the lifting hook 50 is pressed against only the front face of the carriage 10 and it leaves free access to the front face and the two lateral faces. It is therefore very easy to bring one of these faces against the access window of a station of a platen press for loading or unloading by simply sliding the flat tools. It may then be useful to also complete the frame of the station windows with hooks similar to the hooks 72 to ensure the correct positioning in height of this carriage relative to the station, that is to say by placing the slides 13,15 and / or 26 in direct correspondence with the tool holding slides in the station.
  • this same hook can be used for other trolleys comprising at least one flat vertical face comprising a horizontal cross member which is free to access , this basket can be triangular or polygonal.
  • This hook can also be used for handling carriages of other types of plates to be loaded or unloaded by translation through one of the lateral or anterior vertical faces.
