Definitions

  • the present invention relates to a tong assembly suitable for use as part of a glass container transfer apparatus, e.g. for use as a take-out tong cartridge.
  • Glass storage containers for food, drink or other household commodities are typically manufactured in bulk, using high speed manufacturing apparatuses to keep costs low.
  • Such containers are often disposed of after a single use, although they can of course be manufactured for longer term use, if desired.
  • the glass container whether in the form of a bottle, jar, or another form, has an upper rim and a neck located below the rim.
  • the size and shape of the neck can vary between containers. It is generally used for engaging the newly formed container during transfer thereof.
  • the container is shaped by blow moulding molten glass.
  • a newly moulded container is then moved by a part of the apparatus known as a take-out mechanism. This engages the neck and is used to transfer the newly formed container to an area known as the deadplate, where the container can cool and can be moved towards a conveyor by a device known as a pusher.
  • the take-out mechanism generally includes a component known as a take-out cartridge. This is subject to high stresses and to wear. It is removably mounted so that can be replaced and/or repaired when necessary, although this does of course involve shutting down the relevant machinery.
  • the take-out cartridge normally includes a pair of pivotally mounted, opposing tongs that move towards each other through an arc.
  • the cartridge is therefore sometimes also referred to as the take-out tong cartridge.
  • the opposing tongs each carry an engaging means.
  • the engaging means When the engaging means have moved towards each other to a given extent through the arc they can engage the neck of the newly formed container.
  • the arcuate motion is due to the pivoting nature of the tongs, which is driven by a piston that is located in the cartridge and is operably linked to the tongs.
  • the engaging means move away from each other through an arc, again due to movement of the pivotally mounted tongs, which are operably connected to the piston.
  • the piston moves in the reverse direction to the direction in which has moved earlier to bring the engaging means towards each other.
  • This reverse movement of the piston is usually achieved by a reaction of a compressed spring on the piston following earlier compression of said spring as the engaging means are moved together.
  • the engaging means can be of any desired shape or size, provided that they function together in engaging and/or releasing the neck of the container at the desired times and locations. They should of course be shaped so as not to cause any significant damage to the neck during normal use. The size and shape can vary, depending upon the neck of the container.
  • each engaging means may comprise an inner concave surface shaped to engage the circular perimeter.
  • Opposing engaging means may abut one another other when the neck of the container is engaged. This can function as a useful stop so that the neck is not unduly compressed.
  • fingers An engaging means is often known in the art as “the fingers”, given that it may comprise one or more elongate members. As indicated above, fingers will normally comprise curved inner surfaces, so as to complement the neck of the container.
  • fingers may include a heat resistant shield, which may itself be removably mounted (e.g. for ease of repair or replacement). In this case, this part will be shaped for engagement with the neck of the container.
  • a take-out cartridge therefore generally comprises pivoting tongs, with fingers releasably secured thereto, and a reciprocating piston that drives the tongs so that the fingers can move towards each other or away from each other each through an arc.
  • take-out cartridge forms part of the tong head - also known as the "take-out tong head” or "take-out head”.
  • the tong head is operably connected to a tong arm - also known as the "take-out tong arm” or "take-out arm”
  • This arm is operably connected to a shaft that causes the arm to swing through an angle (usually of about 180°) so that a newly formed glass container that is engaged by the engaging means on the tongs is moved towards the deadplate.
  • a belt or chain drive is normally used to drive this shaft.
  • Such apparatuses are themselves normally parts of much larger glass container forming and processing machines.
  • IS machines where IS is an abbreviation for "Individual Section”.
  • These machines include the moulds for shaping the containers as well as the various assemblies, drives, belts, pushers, etc.
  • IS machines with significantly output rates were developed by a successor company, known as "Emhart Glass” and now part of Bucher Industries.
  • Each IS of such machines can make several glass containers at once. Thus they are made in parallel rather than sequentially.
  • GB 2182297 discloses an assembly for a bottle forming machine, comprising a main axle, a housing journalled on said axle for swinging movement about an axis provided by the axle between a bottle pick up position and a bottle deposit position.
  • a spindle is journalled in the housing and carries a tong head, from which depend tongs for gripping bottles and, upon swinging movement, for transferring them between a pick up position and a deposit position whilst hanging substantially vertically.
  • a coupling means is provided that couples the axle and the spindle to maintain the depending position of the tongs during swinging movement of the head, said coupling means comprising complementary toothed wheels or pulleys on the axle and on the spindle, a toothed belt extending around the toothed wheels or pulleys.
  • a belt tensioning means is also provided that is disposed to act on the belt between the two toothed wheels or pulleys so as to maintain the belt under tension, and thereby to eliminate lost motion and/or possible backlash between the toothed wheels or pulleys.
  • Patent Application WO2009/093039 an apparatus is described comprising a release mechanism that can disengage a tong head assembly from a drive when a collision occurs.
  • This Internationa] Patent Application also describes a tensioning device that automatically maintains tension in a drive belt or chain when the assembly is in use.
  • One proposed solution has to provide mechanical links between the tongs. These are sometimes known as anti-wink linkages.
  • the present invention seeks to address, or at least to alleviate, one or more of these problems.
  • a part for a glass container transfer apparatus that comprises a shaft and a plurality of tongs operably linked to the shaft; wherein the tongs comprise glass container engagers, or are shaped so that they can be attached to such engagers, and are arranged so that during use they can move the engagers towards each other manner along a given plane or axis in order to releasably engage the glass container; characterised in that the tongs are guided by a plurality of angled guides that are inclined relative to said plane or axis.
  • the tongs are not pivotally mounted to move through an arc towards each other during engagement of the container by the engaging means.
  • the approach of the present invention therefore goes in a very different direction to that used in the industry for very many decades.
  • the tongs are arranged so that during use they release the container at the appropriate stage (normally in a stable manner onto a deadplate).
  • the tongs preferably move away from each other along a given plane or axis during the release of the conatiner. This movement is desirably in the opposite direction from that in which they move together to engage the container.
  • the plane or axis along which the tongs move during release will of course normally be located at a lower level than the plane or axis through which the tongs move during engagement of the container. This is because the newly formed container will normally be moved from a mould to a deadplate that is located at a lower level than the mould.
  • the two planes or axes (of engagement and of release) will normally be parallel or substantially parallel.
  • the plurality of tongs is desirably a pair of opposed tongs that are arranged so that, when in use, engaging means on each tong moves along a given axis.
  • the part has more than two tongs, with each tong having an engaging means.
  • the engaging means may then move along a given plane.
  • the given axis or plane is desirably horizontal, or at least substantially horizontal.
  • it is horizontal or at only a few degrees from the horizontal (desirably less than 15°, less than 10° less than 5°, less than 3° or less than 1° from the horizontal.)
  • a glass container engager is releasably attachable or releasably attached to each tong.
  • tongs may be manufactured separately from the engagers and the engagers means may be attached to the tongs later on.
  • An advantage of this approach is that the engagers can be added and subsequently removed for replacement or repair, when desired, without having to replace the tongs as well. This is useful given that engagers can become damaged or worn over time.
  • Releasable attachment can of course be achieved by any appropriate means known in the art of mechanical engineering, including bolts, screws, clips, clamps, etc. Whatever releasable attachment means is used, it should allow an engager to be held securely in place when in use, but to be released when repair or replacement is desired. (Bolts are used in the present examples, but as indicated above, there are many other alternatives.)
  • tools such as spanners, screwdrivers, wrenches, Allen keys, etc. may be used.
  • One or more tools may even be provided as part of a kit, as discussed later.
  • said release and/or attachment may be achieved without specialised tools.
  • a release system may be provided.
  • Release systems include, for example, actuators that can be operated at one stage to facilitate release and in another stage to facilitate attachment.
  • Actuators include levers, buttons, switches etc.
  • each tong may already incorporate an engager as an integral part of its structure.
  • the tongs may be manufactured to already include glass container engagers, although this is less preferred.
  • each tong moves along, within, or against, a guide during engagement and/or disengagement of a container
  • one or more tongs are slidably mounted relative to the respective guides.
  • the guides may for example be in the form of one or more guide tracks, guide ramps, guide channels, guide grooves, guide recesses and/or guide surfaces.
