Definitions

  • the present invention relates to a repair kit for a conveyor link chain, which has at least one transport arm projecting laterally over the chain links with a cylinder shoulder at its free end for attaching and fastening a spring-loaded damping element.
  • Can transport chains of this type must also be suitable for driving through an oven in order to dry a layer of lacquer applied to the can.
  • the damping element is made of a heat-resistant plastic, but is nevertheless subject to a certain amount of wear.
  • the damping elements usually wear out earlier than the actual chain links, which is why the driving pin is usually detachably inserted with the corresponding chain links. To overhaul the chain, the entire drive pins including damping elements are removed and replaced with new ones.
  • connection methods between the damping element and the driving pin consist, for example, in that the end of the driving pin is compressed, similar to a rivet. As a result, the damping element is captively secured on the end of the driving pin. Due to the fact that the driver pin is removed, the chain connection is always interrupted at this point, which makes the overall manageability when exchanging all driver pins not exactly easy. In addition to improving the ease of installation, efforts are also being made to reduce the costs for such an overhaul of the chain.
  • the invention is therefore based on the object of achieving an improvement in the overhaul of a conveyor chain which has at least one transport arm projecting laterally beyond the chain sliders with a cylinder shoulder at its free end for attaching and fastening a spring-loaded damping element, by improving the manageability and the Costs are reduced.
  • a repair kit according to claim 1.
  • This is characterized by a helical compression spring with a push-on opening, the inner diameter of which is larger than an outer diameter of the cylinder shoulder of the transport arm and which can be plugged onto it, a damping element with a push-on bore, the diameter of which is larger than the outer diameter of the cylinder shoulder of the transport arm and which can be plugged onto it is, and a locking washer with an inner diameter, the tolerance of which is selected such that the inner diameter of the locking washer is always at least 0.01 mm smaller than a diameter of an associated cylindrical end portion of the cylinder shoulder and the locking washer is releasably pressable thereon.
  • an embodiment is provided in which the inside diameter and the tolerance of the locking washer are selected such that at least an oversize of 0.01 mm, preferably 0.02 mm, and at most 0.1 mm, preferably 0.06 mm, relative to the outer diameter of the associated cylindrical end section of the cylinder shoulder.
  • the inside diameter of the locking washer is 5.78 + 002 mm.
  • the lock washer is hardened in such a way that its hardness is less than the hardness of the cylindrical end section of the cylinder shoulder. As a result, as far as plastic deformations occur, these are absorbed by the locking washer. The outer jacket of the cylindrical end section remains undamaged by the pressing.
  • the damping element can have a truncated cone shape and at its larger diameter end a cylindrical bore shoulder can be incorporated, the base of which can be brought into contact with the locking washer as a stop. This also defines the most extended position of the damping element. The spring travel of the helical compression spring remaining in this extended position then also determines the maximum deflection of the damping element.
  • the damping element can consist of a heat-resistant plastic.
  • a friction coefficient that is as high as possible is useful because the can is not moved when the damping element rebounds.
  • a hard rubber has proven itself.
  • the depth of the cylindrical arch shoulder and the length of the helical compression spring can be selected such that the transport arm does not protrude beyond the damping element when the helical compression spring is installed and compressed. This means that under no circumstances will there be any contact between the driving pin and the can bottom, although no covering of the end face of the transport arm has to be provided.
  • a mounting mandrel for opening the locking washer which has an end designed as a striking head and a mounting end, with means for holding the locking washer and a stop bore being provided at the mounting end and the diameter of the attachment percussion bore is larger than the outer diameter of the cylinder shoulder of the transport arm and the depth of the stop bore determines the impact dimension of the locking ring by the base of the stop bore can be brought into contact with the end face of the support arm.
  • a mounting mandrel allows the locking washer to be easily and directly attached to the transport arm using a hammer.
  • the stop bore defines the exact axial degree of slip on the cylindrical end of the transport arm.
  • the depth of the stop bore can advantageously be 2-4 mm, preferably 2.65 + 0.1 mm. Such a distance from the end face of the cylinder shoulder is sufficient to achieve a durable press fit.
  • the mounting mandrel can have at its mounting end coaxial to the mandrel axis and to the stop bore a bore shoulder surrounding the stop bore, which has an inside diameter that is essentially the same or slightly larger than an outside diameter of the locking washer.
  • the locking washer is pre-positioned through the hole shoulder. This can e.g. be made with a fitting dimension so that the locking washer can be inserted into it with slight pressure. Furthermore, this facilitates the coaxial placement and, in particular, receiving of the cylinder shoulder in the stop bore.
  • a further advance in ease of assembly can be achieved in that the assembly end of the assembly mandrel is magnetic at least in the area of the bore shoulder and the locking washer is made of steel.
  • the locking washer is held in its position at the end of the assembly mandrel by means of magnetism, which is why a tricky prepositioning on the transport arm can be eliminated.
  • the lock washer can have a different color than the support washers. The user can therefore immediately see which pane last, e.g. with the help of the assembly mandrel.
  • the invention relates to a can transport chain with chain links and at least one transport arm projecting laterally over the chain links with a cylinder shoulder at its free end for attaching and fastening a spring-loaded damping element.
  • the chain is characterized in particular by the fact that at least one cylindrical end section of the cylinder shoulder is produced with a precise outer diameter, the tolerance of which is selected such that it is always at least 0.01 mm compared to an inner diameter of a locking washer of the repair kit according to one of claims 1-16 is larger and this can be releasably pressed onto the end section.
  • releasably compressible means a non-destructive detachment of the locking washer, which can be carried out using common aids, such as special pulling pliers.
  • At least the cylindrical end section is hardened, preferably at least 600 HV 10, so that the cylinder shoulder is not damaged by the locking washer, and the damping element can be replaced several times.
  • FIG. 1 is a partial view of a can conveyor chain in full section
  • Fig. 3 shows the driver pin of the transport arm from Fig. 1 in an enlarged

  • two articulated points lying next to one another and formed by one and the same outer chain link 2 have a somewhat different structure.
  • the two outer plates 7 are connected to one another by a receiving sleeve 9 which projects laterally beyond the outer plates 7 on both sides.
  • the inner tabs 8 are connected to one another by a sleeve 10 which is larger in diameter than the sleeve 5 in order to receive the receiving sleeve 9 on the inside.
  • the adjacent Geienk 3 which belongs to the same outer chain link 2, differs from the normal joint structure only in that the locking bolt 11 connecting the outer plates 7 protrudes a good distance on one side over the outer plate 7.
  • the receiving sleeve 9 now serves as a plug-in receptacle for positioning a transport arm 12 projecting on one side of the chain.
  • the transport arm 12 essentially comprises a cylindrical rod-shaped driving pin 13, on the free end region of which a truncated cone-shaped, spring-loaded damping element consisting of a heat-resistant plastic is arranged.
  • the driving pin 13 has a cylindrical plug-in receptacle 15 which can be inserted into the receiving bore of the receiving sleeve 9 with a precise fit.
  • This cylindrical plug-in receptacle 15 is followed by a cylindrical press fit, onto which a locking tab 17 is pressed.
  • the locking tab 17 has a second bore which is in alignment with the locking pin 11 and is also inserted with the latter, so that the driving pin 13 is held in its angular position.
  • a securing element 18 ensures that the driving pin 13 together with the tab 17 can no longer be removed from the chain link.
  • the diameter of the driving pin 13 increases again, so that an attachment blow 19 for accurate positioning of the locking tab 17 is present.
  • annular groove 20 which is smaller in its inner diameter than the diameter of the cylindrical plug-in receptacle 15, so that the annular groove 20 serves as a predetermined breaking point in the event of overload (see also in particular FIGS. 3 and 4).
  • the driving pin 13 has a cylindrical shoulder 21, the cylindrical end section 22 of which has been processed with particular care. At least the cylindrical end section 22 is case hardened to a minimum of 600 HV 10.
