Abstract
Abstract:
A mechanism for conveying articles comprises a rotary drum divided into a pressure chamber and an exhaust chamber. Conduits supply pressure air to the pressure chamber and exhaust air from the exhaust chamber, Each of a plurality of suction pump tubes extends between the two chambers for air flow therethrough for generating suction in a transverse tube. Each of a plurality of suction pipes is connected to a respective transverse tube to receive such suction and thereby hold an article against the mechanism.

Description
~z~
A conveying mechanism The present invention relates to a mechanism for conveying articles. Such mechanism comprises a rotary drum divided into a pressure chamber and an exhaust chamber; (b~ conduits for supplying pressure air to the pressure chamber and for exhausting air from the exhaust chamber; (c) a plurality of suction pump tubes each extending between the two chambers for alr flow there-through for qenerating suction in a transverse tube; and (d) a plurality of suction pipes each connected to a transverse tube to receive such suction and thereby hold an article against the mechanism.
The accompanying drawings illustrate an embodiment of the invention.
Figure 1 is a front view of an example of a machine in which such embodiment is used;
- Figure 2 is a longitudinal sectional of the embodiment;
and Figure 3 is a sectional view taken along the line III
in Figure 2.
A rotary drum 1 is made airtight by end members 2 and 3. The inside of the drum is divided into chambers 5 and 6 which are separated by a partition 4. Coaxial conduits 7 and 8 extend along the line of the deum, the conduit 7 ~, ~
having openings 9 to the chamber 5 and the conduit 8 communicating with the chamber 6.
Although in the illustrated embodiment the conduit 7 also serves as the shaft, there can be a separate shaft, if preferred.
A plurality of suction pump tubes 10 are fixed in the chamber 5 and each communicates with a suction pipe 11 having a vacuum generating portion lOa opening into a pressure por~ion lOb communicating with the chamber 6 by a pipe 12.
High pressure air supplied from a suitable source, such as a compressor (not shown), passes through the conduit 8 to the ehamber 6 which thus serves as a pressure chamber.
From here it passes through each pipe 12 to respective suetion pump tubes 10, whereby a vacuum is generated in eaeh suction pipe 11. The air is subsequently discharged from an exhaust hole 13 to the chamber 5 whieh thus serves as an exhaust ehamber. The air then passes through the openings 9 to leave the machine through the conduit 7.
The pressure chamber 6 serves as a reservoir to stabilize the air pressure supplied to each of the suction pump tubes, even in the event of ~luctuations in air consumption or leakage. As a result, the suction foree in the pipes 11 can be maintained substantially constantO
Such a mechanism is useful as part of the machine shown in Figure 1 for holding a paekage A on the drum 1 (here shown at C) for transferring sueh a paekage A (cut from a strip A' of such paekages by a eutter B) to a series of artieles D on a further wheel. Such meehanism is thus useful as a transfer mechanism to form part of the machine diselosed in eopending Canadian patent application Serial No. 444,362 of Y. Utsumi filed December 28, 1983 and in the companion applications referred to therein.
