CBOSBIE, OF WASHINGTON, PENNSYLVANIA, ABSIGNOR '10 HAZE-ATLAS GLASS COMPANY, 01 WHEELING, WEST VIRGINIA, A CORPORATION 01 WEST VIRGINIA ems ramsma arraaarus Application fled April 22,
This invention relates to take-out mechanisms for use in conjunction with forming machines for glass articles and is similar in some respects to the take-out device disclosed in the patent of James W. Ross, No. 1,858,642, granted May 17, 1932.
One of the objects of the invention is to provide a take-out mechanism which is more simple in construction and more efiiclent in operation than those previously known.
Another object of the invention is to provide a take-out mechanism which is capable of functioning with forming machines 1n which two articles are formed simultaneously, and which will simultaneously grasp two articles, transport them to a conveyor and release them.
Other objects and advantages of the 1nventionwill be apparent from the follow ng description when taken in connection with the accompanying drawing, in which,
Figure 1 is a perspective view of the complete device with parts broken away to more clearly show the construction, and
Figure 2 is a plan view of the device, with parts in section, on a smaller scale.
Referring to the drawing in more detail, the numeral 1 indicates a base plate for the mechanism and which may be supported in any suitable manner adjacent the forming machine. Mounted 'on one end of plate 1, as by bolts or the like, is a standard or bracket 2 which forms a support for an operating cylinder 3.
The cylinder 3 is secured in upright position on the bracket 2 as by means 'of bolts 4 and is supplied with motive fluid, preferably compressed air, by means of pipe lines 5. These lines are preferably provided with ordinary hand valves (not shown) to control the volume of fluid supplied to opposite ends of the cylinder; and the admission and exhaust of fluid pressure is timed in accordance with the operation of the forming machine, by any ordinary and well known timing device.
The piston 6 of cylinder 3 is mounted on a piston rod 7 which carries an extension 8 of rectangular cross section and provided with teeth to form a rack bar 9. This rack 1982. Serial No. 608,973.
meshes with a pinion lO keyed to a horizontal shaft 11. The shaft 11 is mounted in suitable bearings 12 and 13 on the base plate 1, and it will be obvious that the reciprocations of the rack 9 will cause the shaft to oscillate in its bearings. The length of the piston stroke andthe diameter of the pinion.
alignment with the shaft 11. These rods 18 and 19 are secured to twin pistons 20-20 mounted in a cylinder 21 supported on plate 1.
Slidably mounted in a pair of openings in the head'15' of crankarm 15 is a pan of rods 22 and 23 which jointly carry two pairs of jaw arms 24, 25, 26 and 27. The rods 22 and 23 are also supported in the heads 16' and 17 of arms 16 and 17. I It is to be noted however that while the rods are both slidably mounted in the head 15' they are fixed with respect to the one or the other of the heads 16' and 17. For instance, the rod 22 is clamped to the head 17' by means of a clamping bolt 17" while it is slidable with respect to head 16'. Likewise, rod 23 is clamped to head 16' by bolt 16" but is slidably associated with head 17. It will be apparent therefore that the rods 22 and'23 are caused to reciprocate in opposite directions as motive fluid is alternatel admitted to the middle and ends of the cylinder 21.
So also, the jaw arms 24', 25, 26 and 27 are each provided with twt openings to ro-' vide for'special connections with the ro s 22 and 23. The arms 24 and 26 are provided with bolts 24' and 26 for clamping. .the armsto the rod 23 while the rod 22 is slidably mounted in these arms. Arms 2.5 and 27 are provided with bolts 25 and 27' for clampingthese arms to the rod 22 while the rod 23 is freely slidable with respect to these arms. It will be apparent therefore that the reciprocation of the rods 22 and 23 will cause the arms of each pair tomove toward and from each other.
Grippers 28 are bolted to the arms 24 to 27, inclusive, and preferably have their inner arcuate faces slotted or grooved as indicated at 29, to facilitate gripping the rim of the ware being handled. Obviously these grippers are caused to grip or release the ware in accordance with the movements of the pistons 2020 and the rods 22 and 23 operatively connected therewith.
Numeral 30 refers to a port through which fiuid pressure is admitted to the center of the cylinder 21, to cause the pistons 20 to move away from each other; the fluid pressure being eventually exhausted through the same port. Numeral 31 refers to a port for simultaneously admittin pressure to opposite ends of the cylinder t rough passages 32, 32; the pressure being eventually exhausted through the same passages and ort.
p Pipe lines (not shown) lead to the ports 30 and 31, and the timing of the admlssion and exhaust of the fluid pressure is controlled by any ordinary and well known timing device. If desired, ordinary volume control hand valves may be provided in the lines leading to the ports 30 and 31.
In the operation of the device, the parts being in the positions indicated in Figure 2, the articles A, shown in dot and dash outline, have been presented to the grippers 28 in the usual way. Fluid pressure 15 now admitted to the opposite ends of the cylinder- 21 to force the pistons 20 toward each other to their innermost positions, as indicatedin Figure 1. This movement of the pistons op erates through arms 16-17 and rods 2223 to move the jaws of each pair of gr ppers toward each other to cause them to grip the articles as indicated.
Fluid pressure is now admitted to the upper end of cylinder 3 to move the rack 9 down, thereby rotating the pinion 10 and shaft 11 through substantially 180. The grippers 28 and the ware clamped therein are then swung through approximately 180 to lug the ware over a conveyer or chute.
leading to a leer.
Fluid pressure is now admitted to the center of the cylinder to drive the pistons awayfrom each other towards the ends ofthe cylinder, thereby reversing the movement of the rods 22-23 and separating the grippers 2828 to release the articles and deposit them on a conveyer or'chute to .be carried to the annealing leer.
Fluid pressure is now admitted to the lower end of cylinder 3 to lift the rack 9, thereby swinging the parts back to their original preferred form of construction, but various chan es and modifications may be made without eparting from the spirit of the invention; and it is intended that all such changes and modifications be included within the scope of the appended claims.
