Definitions

  • Cartridge for holding a plurality of disks
  • the present invention relates to a cartridge for holding a plurality of disks, preferably but not exclusively glass disks or wafers.
  • the cartridge comprises two housing parts that can be fit together to substantially form the cartridge and define a receiving space for the disks.
  • a plurality of holding members is provided on the inner side of the housing parts, which are arranged in such position that when the disks are engaged with the holding members each holding member contacts a disk at two or more locations, so as to hold the disks in a parallel position with respect to each other.
  • the housing parts form a bottom part and a top part for the cartridge.
  • the top part fits on top of the bottom part and cover plates are used to cover openings formed by the housing parts and to serve as locking arrangement to fix both housing parts with respect to each other.
  • One of the housing parts is used to contain the disks on a machine clamp of a machine for further processing the disks.
  • the object of the invention is to improve the prior art cartridge, particularly with a view to facilitating the cartridge manufacture.
  • the cartridge according to one aspect of the invention has the features of claim 1.
  • both housing parts are identical, which means that only one type of housing part need to be produced to form the cartridge.
  • the housing parts form a bottom part and a top part of the cartridge.
  • the disks must therefore be inserted perpendicularly to the opening of the housing parts which is surrounded by the contact surface. This is the easiest way to insert and remove cartridges into and from the cartridge.
  • the configuration of the positioning members according to claims 3 to 5 lead to simple positioning members, while such positioning members easily allow an arrangement in which the housing parts are identical.
  • the embodiment of claim 6 is especially intended for a cartridge of which one housing part is intended to be used on a standardised machine clamp.
  • Such machine clamp is present on a machine for further processing the disks present in the cartridge.
  • the machine clamp has a positioning ridge against which the contact surface on the free edge of the first side wall should be positioned.
  • a positioning pin is projecting from this positioning ridge.
  • the housing part Due to this vertical translation, the housing part can be kept in a position with the disks horizontally, so that there is no risk of the disks falling out and no special measures are required to prevent the disks from felling out.
  • the position of the positioning members may be selected such that the positioning members can be kept simple and effective, but still allow the housing part to be placed on the machine clamp in a vertical translatory manner.
  • the embodiment of claim 8 leads to the advantage that the marker enables a person which should position the housing part on the machine clamp to do this in an easy manner, as the operator is able to see the marker projecting from the cartridge in his direction.
  • the embodiment according to claim 9 provides the advantage that the disks are held in a stable manner within the cartridge.
  • the use of such cushioning element prevents rattling and prevents the disks from being damaged or becoming polluted with plastic particles loosening from the cartridge due to the rattling of the disks.
  • the embodiment of the cartridge according to claim 10 provides a very simple cushioning element.
  • this soft plastic elongate element is clamped in a recess in the inner wall of the housing parts. This obviates the need for fixing means such as adhesive which could have a detrimental effect on the disks.
  • the object of the invention is further achieved by the cartridges according to the invention as defined in the claims 15 and 16.
  • Fig. 1 is a perspective exploded view of an embodiment of the disk cartridge according to the invention together with a plurality of disks.
  • Fig. 2 is a perspective view of the cartridge of Fig. 1 in assembled and closed condition.

  • Figs. 9 and 10 are a view of a machine clamp.
  • FIG. 1 show an embodiment of a cartridge which is intended to be used for the transport and storage of glass disks D. These glass disks are the basis for forming a master disk for the production of optical disks, such as CD's or DVD's, for example. It should be understood, however, that the cartridge could also be used for other disk- like objects, such as wafers for the production of computer chips and the like.
  • the cartridge comprises two housing parts 1 that can be fit together to substantially form the cartridge and define a receiving space for the disks D.
  • the housing parts 1 are identical so that only one type of housing part is needed to form the cartridge.
  • one housing part 1 forms the bottom part of the cartridge and the other housing part forms the top part.
  • Each housing part 1 encloses half of the disks when they are inserted.
  • Each housing part 1 has a first side wall 2 and a second side wall 3, as well as a circumferential wall 4.
  • the side walls 2 and 3 are substantially flat and extend parallel to each other, whereas the circumferential wall 4 has a semi-circular cross- section.
  • a semi-circular recess 5 which is coaxial with the circumferential wall 4.
  • These circular openings can be covered by cover plates 6 which are not only used to cover the openings but also form part of a locking arrangement to fix both housing parts 1 with respect to each other.
  • both the cover plates 6 and the edges around the recesses 5 are provided with bayonet catch members 7 and 8 to form a bayonet catch when the cover plate 6 is placed on the opening in the housing parts 1 and turned slightly. In this position, the receiving space in the cartridge is fully closed.
  • the cartridge is packaged in a aluminium laminate bag (not shown) protecting the cartridge and disks D contained therein against dust and humidity.
  • the holding members include a plurality of ribs 9 and 10, respectively.
  • the ribs 9 are provided at the bottom of the semi-cylindrical receiving space in the housing part 1, while the ribs 10 are provided at the sides of the receiving space near the entry opening of the housing part 1.
  • the ribs 9, 10 are provided in rows along the width of the circumferential wall 4 of the housing part 1 and are parallel to each other and spaced at such distance that a disk D fits between two adjacent ribs 9, 10.
  • the edges of the ribs 9, 10 remote from the wall 4 are slightly tapered to facilitate the insertion of a disk D between two adjacent ribs 9, 10.
  • a plurality of disks, in this case 20 are held in the cartridge in a parallel position with respect to each other.
  • Each disk D is held at four regularly spaced locations by the ribs 9, 10 which contact each disk.
  • the housing parts 1 are provided with cushioning elements which keeps the disks slightly under pretension, in this case in a direction parallel to the disk surface (or perpendicular to their edge).
  • the cushioning elements in this embodiment comprise soft, plastic or rubbery elongate elements 11 (see Fig. 1) which might be shaped as rods, tubes or the like which extend perpendicularly to the ribs 9, 10 along the width of the circumferential wall 4.
  • the cushioning elements 11 are provided on either side of the ribs 9, so that the disks D are engaged at four spaced locations by the cushioning elements 11.
  • the cushioning elements 11 might be extruded from PE or another plastic material that can exert an elastic force on the disks D and that has the other required material properties, such as being hydrocarbon emission free below temperatures of circa 80°C.
  • the material of the other cartridge parts should conform to this material requirement to prevent hydrocarbon deposits on the surface of the glass disks.
  • the cartridge is made from plastic by injection moulding or the like.
  • Recesses 12 are formed in the circumferential wall 4 to receive the cushioning elements 11 therein.
  • the cushioning elements 11 are clampingly received in the recesses 12, so that no additional fixing means, such as adhesive, is requirement to hold the elongate elements.
  • Fig. 7 it is shown that at the position of the recesses 12 there are formed stabilising feet 13 on the outer side of the circumferential wall 4 in order to provide a stable base for the cartridge.
  • the stabilising feet 13 enable a cartridge to be put on a support without the risk of rolling on the supporting surface.
  • the position and shape of the stabilising feet or other means may be varied, but in this embodiment, the stabilising feet 13 locally provide additional wall thickness of the wall 4 to enable the recesses 12 to be formed in the wall 4.
  • the housing parts 1 are provided with contact surfaces 14 with which the housing parts 1 fit onto each other.
  • the contact surface 14 of one housing part 1 lies within one plane and defines an open end of the receiving space in the housing part 1.
  • the housing parts 1 are provided with positioning members.
  • the positioning members comprise co-operating pins and holes, in particular pins 15, 16 and holes 17 and 18.
  • the pin 15 and hole 17 are formed on the free edge 19 of the second side wall 3 which forms a part of the contact surface 14.
  • the pin 16 and hole 18 are formed on the free edges 20 and 21, respectively, of the circumferential wall 4.
  • the free edge 22 of the first side wall 2 is free of positioning members. As is shown in Fig.
  • the co-operating pins and holes 15/17 and 16/18 are symmetrically positioned with respect to a central cross plane through the housing part 1, so that the pins 15, 16 of one housing part 1 fit into the corresponding holes 17, 18 of the other housing part 1 put on top of the bottom housing part 1.
  • first and second side walls 2, 3 of the housing part 1 are not identical.
  • positioning ribs 23 on the first side wall 2 are arranged in a different position than ribs 24 on the second side wall 3.
  • the first side wall 2 comprises further positioning ribs 25 which not only protrude from the side wall 2 in a perpendicular direction, but also parallel to the side wall 2 in a direction away from the contact surface 14. Consequently, the positioning ribs 25 project from the circumferential wall 4.
  • the side wall 2 has small recesses 26 formed therein. These recesses 26 are formed in the outer surface of the first side wall 2 adjacent the free edge 22 thereof. In this embodiment, the axis of the recess is positioned 70,3 mm from the transverse centre line of the housing part.
  • the configuration of the first sidewall 2, i.e. of the positioning ribs 23, 25 and the recesses 26, is determined by the function of this first side wall 2 as a base or bottom wall of the housing part 1 when placed on a machine clamp in a machine for automatically taking out the glass disks D for further processing.
  • This machine clamp is standardised and the positioning ribs 23 and 25 are intended to position the housing part 1 on the machine clamp. Figs. 9 and 10 show such machine clamp.
  • This machine clamp has a base 30. Ridges 31 thereof should co-operate with the positioning ribs 23 and protruding part 23 fit between the positioning ribs 25.
  • a ridge 33 functions as a stop for the free edge 22 of the second side wall 2.
  • the clamping member 34 is allowed to fit on the second (top) side wall 3 of the housing part 1 in order to clamp it on the base 30.
  • a pin 35 protrudes horizontally from the ridge 33.
  • the housing part 1 can now be placed on the base 30 of the machine clamp by a vertical translatory movement with the disks D in a horizontal position. Then, the recess is open such that the pin 35 can enter the recess 26 when the housing part 1 is lowered onto the base 30 in a horizontal position. There is no risk of the disks D falling out and so no special measures are required to prevent the disks D from felling out.
  • the positioning ribs 25 which protrude from the circumferential wall 4 enable an operator which is positioned on the side of the housing part 1 facing away from the contact surface 14 to see the positioning ribs 25 to easily align these ribs 25 with the protruding part 32 on the base 30 of the machine clamp.
  • the positioning ribs 25 operate as markers which facilitate the manual placement of the housing part 1 on the base 30.
  • the invention provides a disk cartridge which is able to allow the disks D to be stored and transported in a safe manner, while the cartridge also facilitates the handling of the cartridge when placing it on a machine clamp. Due to the identical configuration of the housing parts 1, manufacturing costs are reduced.
  • the positioning members could be designed as co-operating ridges arranged in other positions.
  • the holding members could be shaped as pins or interrupted ribs or the like.
  • the locking arrangement for the housing parts could be integrated in the housing parts and could be designed as snap parts, for example.
