Description

The present disclosure is directed to platforms and production machines and, more particularly, to traversable platforms and to glassware forming machines.

BACKGROUND AND SUMMARY OF THE DISCLOSURE

The science of glass container manufacture is currently served by the so-called individual section (IS) machine, which includes several manufacturing sections, each having multiple operating mechanisms for converting gobs of molten glass into hollow glass articles and transferring the articles through successive stages of the machine section. In general, an IS machine may include a source of glass, a mechanism for generating streams of molten glass, a shear mechanism for cutting the molten glass into individual gobs, and a gob distributor for distributing the individual gobs among the individual machine sections. Each machine section may include several blank molds in which glass gobs are initially blown or pressed into blanks, several blow molds in which the blanks are blown into containers, and several invert arms for transferring the blanks from the blank molds to the blow molds. Also, each machine section may include a take-out mechanism for removing the molded containers onto a deadplate, and a sweepout mechanism for transferring the containers from the deadplate onto a conveyor that receives containers from all of the sections and conveys the containers downstream to a loader for transfer to an annealing lehr. Further, each section may include operating mechanisms to close mold halves, move baffles and plungers, control cooling wind, and the like. U.S. Pat. No. 4,362,544 includes a background discussion of the art of both “blow and blow” and “press and blow” glassware forming processes, and discusses an electropneumatic individual section machine adapted for use in either process.

A general object of the present disclosure, in accordance with one aspect of the disclosure, is to provide a platform that is traversable, for instance, along a machine to enable worker access to out-of-reach portions of the machine, for example, upper portions of a glassware forming machine, and that is pivotable, for instance, away from the machine to avoid interference with portion of the machine when repositioning the platform along the machine.

The present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.

A platform system in accordance with one aspect of the disclosure includes a guide establishing a platform translation axis and having upper and lower surfaces, a carriage translatably coupled to the guide along the platform translation axis and engaged with the upper and lower surfaces of the guide, a platform coupled to the carriage and including at least a portion that is pivotable in a direction transverse to the platform translation axis, and a stepway movably coupled to at least one of the carriage or the platform.

In accordance with another aspect of the disclosure, there is provided an individual section glassware forming machine that includes a linear conveyor for receiving and transporting articles of glassware, and a plurality of individual glassware forming sections disposed adjacent to each other along one side of the conveyor and operable to form articles of glassware from molten glass gobs and transfer such articles of glassware onto the linear conveyor. The machine also includes a platform system disposed on a side of the conveyor opposite the sections, and including a track disposed in a fixed position spaced above a floor, adjacent and parallel to the linear conveyor on a side of the conveyor opposite the sections, and establishing a platform translation axis and having upper and lower surfaces. The platform system also includes a platform moveable along the track and including a portion translatably coupled to the track along the platform translation axis and engaged with the upper and lower surfaces of the track, and also including at least a portion that is pivotable in a direction transverse to a longitudinal direction along which the track extends.

The machine portion with which the second support portion 160 may be releasably engageable, may include one or more heat shields of the machine 10. The support portions 148, 160 may be carried by, or may be part of, the base portion 146.

Still referring to FIG. 4, and as also shown in FIG. 1, the platform system 100 also may include hand rails 162 that may be carried by the platform 106. For example, the hand rails 162 may be laterally spaced apart on either sides of the platform 106. Also, the hand rails 162 may include rearward ends 164 coupled to the base portion 146 of the platform 106, and forward ends 166 coupled to the bridge portion 150, for example, to the intermediate step 154. The hand rails 162 may be fastened, welded, or otherwise coupled to the platform 106 in any other suitable manner.

The platform 106 may be pivotably coupled to the carriage 104 about the platform pivot axis P, which may be substantially, but not necessarily perfectly, parallel to the platform translation axis. As used herein, substantially parallel includes within ten angular degrees. Accordingly, the platform 106 may be pivotable with respect to the carriage 104 between the horizontal position of the platform 106 over the carriage 104, for example, as shown in FIGS. 1 and 3, and the angled position of the platform 106 angularly spaced away from the carriage 104 and the horizontal position, for example, as shown in FIG. 6.

Referring to FIGS. 4 and 5, the stepway 108 may be pivotably coupled to the carriage 104 and/or the platform 106 to pivot with respect thereto about a stepway pivot axis S. Accordingly, the stepway 108 may be foldable away from, toward, and against, a portion of the platform 106. The stepway 108 may be pivotable between a first position extending below the stepway pivot axis S and, as illustrated in FIG. 4, a second position extending above the stepway pivot axis S when the platform 106 is in the horizontal position. The stepway pivot axis S and the platform pivot axis P may be coaxial and substantially, but not necessarily perfectly, parallel with the platform translation axis T.

Referring to FIG. 4, the platform system 100 further may include a hangar or latch 168 for selectively engaging the stepway 108 and holding the stepway 108 in a raised position. The latch 168 may be carried by one or both of the handrails 162. For example, the latch 168 may be pivotably coupled to a side of a handrail 162 for retention of a rung, or other suitable portion of the stepway 108, or to another component that may be coupled to the stepway 108. Also, the stepway 108 may include one or more floor engagement devices 170. In the illustrated embodiment, the device 170 includes a caster having a bracket 172 that may be fixed to an end of the stepway 108 that is distal with respect to the stepway pivot axis S, and a roller 174 carried by the bracket 172. The roller 174 may be rotatable along a fixed rotational axis C that may be substantially parallel with the stepway pivot axis S. In other embodiments, the device 170 may include stationary or movable feet, rotatable casters, or the like (not shown).

Still referring to FIG. 4, and as also partially shown in FIG. 5, the platform system 100 also may include a restraint 176 coupled to the carriage 104 and the platform 106 to limit pivotal or angular travel of the platform 106 relative to the carriage 104. For example, the restraint 176 may include a bracket 178 pivotably coupled to the carriage 104, and having a guide slot, which may include a first portion 180 into which a pin 182 of the restraint 176 may extend away from the platform base portion 146, and through which the pin 182 may travel when the restraint bracket 178 is pivoted about a restraint pivot axis R to release the platform 106 for pivoting. The guide slot also may include a second portion 184 disposed at a greater-than-zero angle with respect to the first portion 180 and into which the pin 182 may travel when the platform 106 is pivoted away from its horizontal position about the platform pivot axis P.

Accordingly, and referring to FIGS. 6 and 7, the platform 106 may be pivoted toward and to its angled position angularly spaced from the horizontal position, and may be restrained by the restraint 176 when the restraint pin 182 (FIG. 7) is at the end or limit of the second portion 184 of the restraint bracket guide slot. Accordingly, the platform 106 is traversable along the machine 10 via the carriage 104 and the guide 102 to provide lateral access thereto, and is pivotable away from the machine 10 to avoid interference with portions (e.g. elements 16—FIG. 1) thereof when the platform 106 is repositioned laterally along the machine 10.

FIGS. 8-11 show another illustrative embodiment of a platform system 200. This embodiment is similar in many respects to the embodiment of FIGS. 1-7 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.

The platform system 200 is substantially similar to the system 100 illustrated in FIGS. 1-7, with a few exceptions. In one example, a platform 206 may include a second support portion 260, which may include a fixed member, or even one or more roller members to assist with translation of the platform 206 with respect to the machine. In another example, the platform 206 itself is not necessarily pivotable with respect to the carriage 104, but portions of the platform 206 are pivotable in a direction transverse to the platform translation axis. For instance, the second riser 158 and/or the extension 152 may be pivotable about pivot axes 159, 153.

In one embodiment, and referring to FIG. 11, the extension 152 may be pivotable about the extension pivot axis 153 with respect to the second riser 158 and may rest against the second riser 158 in a retracted or folded condition. In another embodiment, and referring to FIG. 12, the second riser 158 may be pivotable about a riser pivot axis 159 with respect to the step 154. In a further embodiment, and referring to FIG. 13, both the extension 152 and the second riser 158 may be pivotable wherein the extension 152 may rest against the step 154 and/or the first riser 156 in a retracted or folded condition of the extension 152 and the second riser 158. In an additional embodiment, although not shown, the second riser 158 may be fixed or non-pivotable but the extension 152 may be pivotably coupled to second riser 158. In any embodiment, the extension 152 may be pivotable with respect to the bridge 150.

Accordingly, with respect to FIG. 10, the platform 206 is traversable along the machine 10 via the carriage 104 and the guide 102 to provide lateral access thereto, and includes one or more portions pivotable away from the machine 10 to avoid interference with portions (e.g. elements 16) thereof when the platform 206 is repositioned laterally along the machine 10.

As used herein, directional words such as top, bottom, upper, upward, downward, lower, radial, circumferential, lateral, longitudinal, transverse, vertical, horizontal, and the like are employed by way of description and not necessarily limitation.
