  • This invention relates to valve blocks and particularly to valve blocks incorporating a set of pneumatic valves for controlling the operation of a Hartford IS Glassware Forming Machine.
  • Conventional IS Glassware forming machines comprise one or more sections in each of which one, two or three gobs of molten glass are formed into bottles or other glassware by handling apparatus which is operated pneumatically.
  • Each part of the handling apparatus which carries out a separate step in the formation of the ware from the glass gobs is controlled by a pneumatic valve, and normally 19 or 21 separate valves are required to control the complete forming sequence.
  • Each valve is conventionally operated by a separate lever and latch system and each lever and latch system is controlled by a respective rotatable and adjustable cam. All the cams are normally housed together on a timing drum in a space some 21 inches wide, the width of this space being the widest part of the section of the machine.
  • valves are arranged in two rows in a single valve block which also contains at least one common plenum chamber communicating with all the supply or exhaust ports of the pneumatic valves, the resulting valve block is very compact and can easily be incorporated into the available space in an IS glassware forming machine.
  • valves which we propose to use in our electronically controlled glassware forming machine are pneumatic valve combinations.
  • Each valve combination includes a pilot-operated poppet valve which is controlled by pilot air directed to the poppet valve by a solenoid-operated pilot valve.
  • the present invention provides a valve block for an IS glassware forming machine comprising a plurality of valve combinations arranged in two rows, each valve combination comprising a pilot-operated poppet valve having a supply port, an outlet port and an exhaust port and a solenoid-operated pilot valve for directing pilot air to the poppet valve, a pilot line in the valve block common to the pilot valves on all the valve combinations and a plenum chamber located adjacent all the valve combinations and common to either all the exhaust ports or all the supply ports of all the poppet valves.
  • the valve block includes two further plenum chambers each associated with either the exhaust ports or the supply ports of each of the poppet valves in respective ones of the rows of valve assemblies.
  • the plenui chamber located adjacent all the valve combinations a common exhaust chamber which is located betwee the two rows of valve combinations.
  • a valve block comprising a plurality of pnei matic valve combinations arranged in two rows, eac valve combination comprising a pilot-operated popp valve having a supply port, an outlet port and an e; haust port, and a solenoid-operated pilot valve for d recting pilot air to the poppet valve, a pilot line in th valve block common to the pilot valves of all the valv combinations, and an exhaust chamber located be tween the two rows of valve combinations and commo to the exhaust ports of all the poppet valves.
  • this valve block fit easily into the space availabl on the IS machine, but also, the arrangement of th valve combinations and exhaust chamber renders th operation of the valve block surprisingly quiet.
  • valve block may be mad even more compact by providing an outlet manifol which communicates with the outlet ports of all th poppet valves and locating the outlet manifold betwee the two rows of valve combinations.
  • FIG. 1 is a front elevation of a preferred embodimer of a valve block in accordance with this invention:
  • FIG. 1A is a front elevation of another embodimer of a valve block in accordance with this invention.

  • FIG. 3A is a partial cross-section of the valve block c FIGS. 1A and 2A taken along the line A--A of FIG 1A.
  • the drawings show a valve block which is made up two castings, 1 and 2, in which are located 21 pnel. matic valve combinations.
  • the valve combinations e) tend laterally across the valve block, as best shown i FIGS. 2 and 3, and are arranged in two rows which e1 tend longitudinally along the valve block.
  • the uppe row includes 1 1 valve combinations, and the lower ro' includes 10 valve combinations, the valve combinatio in each row being vertically offset from each other.
  • Th castings 1 and 2 define an exhaust chamber 43 which located between the two rows of valve combinatior and which is provided with an outlet 44 to the atmt sphere.
  • Th valve combination shown comprises -a pilot-operate poppet valve located in the casting 2 and indicated ger erally by the reference numeral 3, and a solenoit operated pilot valve located in the casting l and ind cated generally by the reference numeral 4.
  • the poppt valve 3 is located in a bore 5 in the casting 2.
  • the box 5 is provided with three enlarged annular portions 6, and 8.
  • the annular portion 8 is connected to a supp] port 9 in the casting 2.
  • Annular portion 6 is connecte to an exhaust port 11 in the casting 2 which communicates with the exhaust chamber 43, exhaust chamber 43 being common to all the exhaust ports of the 21 poppet valves in the valve block.
  • Annular portion 7 is connected to one of 21 outlet ports 10 arranged in one row in an outlet manifold defined in the central portion of the casting 2 between the two rows of valve combinations adjacent the exhaust chamber 43. It will be appreciated that the arrangement of the outlet ports in a single row enables the outlet ports to be connected directly to the existing supply lines of the pneumatic cylinders of a conventional IS glassware forming machine.
  • a piston 12 is located within the bore 5 by glands 13 and 14 and is provided with two enlarged portions 16 and 17.
  • Two abutment rings 18 and 18a are carried and located within the bore 5 by fixed support rings 19, 20, 21 and 22.
  • a spring 23 acts between an enlarged end portion 24 of the spool 12 and the support ring 19 and biases the spool to the left of the bore 5, as shown in FIG. 3, into a position in which the enlarged portion 16 of the spool 12 abuts with the abutment ring 18a.
  • the pilot valve 4 is solenoid-operated and is effective to direct pilot air from a pilot air line 36 in the casting l of the valve block into the poppet valve 3 in order to operate the valve.
  • the pilot line 36 is common to each of the pilot valves in the 21 valve combinations and is shown more clearly in FIG. 1 of the drawings in broken lines.
  • the pilot line 36 is fed with air under pressure from an inlet 42 on one side of the valve block and has two branches 36a and 36b, one for each of the rows of valve combinations, the branches being connected by a cross-bore 36c.
  • the pilot valve 3 includes a bobbin 27 which is threaded into an aperture 26 in the casting l and which carries the windings of a solenoid coil 28.
  • the bobbin 27 is provided with an axial bore 29 which communicates with an enlarged axial recess 30 in the inner end of the bobbin 27.
  • the recess 30 receives a cylindrical core 31 of magnetisable material.
  • One end of the core 31 includes a rubber seal 32 which can abut with and seal the inner end of the bore 29 in the bobbin 27.
  • the other end of the core 31 carries a disc 33 which is shown in FIG. 3 in abutment with a rubber mouthpiece 34 received in one end of an inlet 35 which communicates with the pilot line 36.
  • a spring 37 acts between the disc 33 and the bobbin 27 and biases the core 31 into engagement with the mouthpiece 34 and thereby seals the inlet 35.
  • a bore 40 connects the aperture 26 with the bore Sin the casting 2.
  • All the pilot valves are operated in response to energisation of the solenoids in accordance with a programme of electronic control signals supplied to the solenoids of the valve block by an electronic timing control unit (not shown).
  • the solenoid 28 is de-energized and the core 31 is biased to the right by the spring 37, and the disc 33 on the core 31 abuts the mouthpiece 34 and seals the outlet 35 from the pilot line 36.
  • Any pilot air which does escape past the mouthpiece can pass into the recess 30 in the bobbin 27, through the axial bore 29 and into the atmosphere.
  • the spool 12 of the poppet valve is biased to the left as shown in FIG. 1, so that the enlarged portion 16 is in sealing engagement with the abutment ring 18a and, therefore, prevents passage of pressurized air from the inlet port 9 through the poppet valve.
  • Pressurized air can then flow from the inlet port 9 into the enlarged portion 8 of the bore 5, through the abutment ring 18a, into the enlarged portion 7 and out of the outlet 10 in the manifold 25.
  • This outlet is connected to an operating cylinder of one part of the handling apparatus of the glassware forming machine and the said one part therefore operates for as long as the solenoid 28 is energized.
  • air under pressure in the outlet 10 and in the operating cylinder of the part of the handling apparatus of the glassware forming machine to which the outlet 10 is connected can exhaust through the enlarged portion 7 of the bore 5, the abutment ring 18 the enlarged portion 6 of the bore 5, and the exhause port 11 into the exhaust chamber 43.
  • Each of the pilot valves includes an override device 47 which is manually operable. As shown in FIG. 3, this device comprises a cylindrical barrel 47 which carries at one end a lever 48 which can be grasped by an operator and at its other end a co-axial cylindrical shank 49 of smaller diameter. This shank 49 has a semi-cylindrical extension 50, the planar surface of which is located immediately adjacent the disc 33 of the core 31. Rotation of the barrel 47, about an axis in the plane of FIG. 3 and perpendicular to the direction of movement of the core 31, brings the extension 50 of the shank 49 into engagement with the disc 33 and, therefore, moves the core 31 to the left, as seen in FIG. 3, so that the seal 32 covers the bore 29 and so that pilot air can pass along the bore 40 to operate the poppet valve 12.
  • pneumatic override devices may be incorporated in the valve block.
  • a device could, for example, comprise a three-way tap, one port of which is connected to the bore 29 in the bobbin 27, another port of which is connected to atmosphere and another port of which is connected to the pilot air line 36.
  • the tap of the override device In its normal operating position, the tap of the override device would effect communication between the bore 29 and the atmosphere. In its override position, the tap would direct air at pilot air pressure along the bore 29 into the recess 31 and along bore 40 to operate the poppet valve 3.
  • the inlet ports 9 of the poppet valves 3 are connected individually to a supply of air under pressure. If desired, however, a pair of supply chambers 55, 56 can be provided on the valve block, as indicated by the broken lines in FIG. 2. Each'supply chamber is located adjacent a respective one of the rows of valve combinations and is separated from the exhaust chamber 43 by its associated row of valve combinations.
  • valve combinations, exhaust chamber, pilot line and outlet manifold in the valve block described above is particularly compact, in all three dimensions, and can be located in the space normally occupied by the latch and lever systems used to operate conventional 18 glassware forming machines, without requiring extensive rebuilding of the glassware forming machine. Consequently, the valve block can be used as a conversion unit in the replacement of the conventional mechanical timing system on an existing is machine with an electronic timingsystem.
  • the two castings 1 and 2 in which the valve combinations are located define an exhaust chamber which is large in comparison with the overall size of the valve block, the noise generated by the exhausts of the 21 valves in the valve block during operation of the valves is very low.
  • the plenum chamber common to all the valve combinations is an air supply chamber 55a which communicates with all the supply ports 9a of the poppet valves.
  • the two rows of valve assemblies which are parallel are located in a segment, or slice, of the valve block parallel to one face of the block, the valve combinations in each row extending in opposite directions from a center line along the segment of the block, and the common supply chamber 55a is located in an adjacent segment or slice of the block to one side of the valve combinations and has an inlet 57.
  • a preferred arrangement in this embodiment of the invention includes two further exhaust plenum chambers 43a and 43b each associated with the outlet ports 11a of the poppet valves in respective ones of the rows of valve combinations, and both located in the same segment of the valve block as the supply plenum chamber.
  • Up to 24 valve combinations can be incorporated into a valve block of this construction in two rows of 12, the valve combinations in each row being aligned with each other rather than being offset from each other.
