COVER STORY
PWVJ staff report
two levels to allow full unwrapping with ease of movement. JFW can accommodate one unwrapped pallet outside the depalletizer area, positioned right outside the entrance and one unwrapped pallet inside the depalletizing area. These areas are controlled by motorized gearmotors controlled by variable frequency drives.
The bottles move to the layer-discharge platform where the machine transfers a layer of bottles to the receiving table. Four guides, electro-pneumatically activated, square and transfer a layer of bottles onto the receiving table. A set of clamps holds the tier sheet during the transfer of the bottles. An independent layer-centering device holds the layer below the one being transferred to guarantee stability of the pallet during the sweeping operation.
The Emmeti depalletizer on each line has automatic and independent dunnage removing devices with vacuum- generated suction cups. Motorization of rotating and vertical motions has gearmotors controlled
.
by variable frequency drives and encoders. The dunnage is placed inside a magazine and stacked and stored for later retrieval by a fork truck driver.
Emmeti/Logik depalletizers are designed to recall any pallet pattern programmed and stored inside the touch screen operator console. JFW receives some of its bulk bottles inside thermoformed trays that Emmeti’s Pick & Place Head is designed to receive and remove bottles from inside the trays, and then the head removes the trays into the appropriate dunnage magazine. Thermoformed trays are often returned to the glass manufacturer for reuse.
One Bertolaso EPICA 60/2100 automatic Low Vacuum Filler, (this page) equipped with sixty filling valves with a maximum speed of 250 750ml bottles per minute, has been inserted into an existing line. It is electronically synchronized with an existing Bertolaso bottle blower, 12-head Bertolaso corker, and screw-capper.

ackson Family Wines (JFW, Santa Rosa, CA) has converted two bottling lines to receive bulk glass in place of bottles in reshippers in early 2012. The conversion from the labor-intensive process of depalletizing reshippers of glass bottles has reduced the potential for injuries and damage to reshippers and partitions.
Emmeti USA provided engineering, design, and implementation for the entire installation-upgrade of bottling equipment. Emmeti engineers developed a line layout that reused as much of the existing conveyors and equipment
.
as possible.
.
JFW benefits from two brand new lines, while still utilizing selected pieces of conveyor and some of their existing machines, to reduce overall costs, while incorporating advanced technology to automate the lines and achieve higher efficiency of 250 bottles per minute (18,000 per hour). Emmeti engineers developed and wrote the software to control the entire two lines, not only Emmeti equipment, but all other equipment supplied by Collopack Solutions on the two lines.
Two automatic Bulk Depalletizers model Lobster (cover photo) are used to remove layers of product that are not inside of a case. Emmeti’s model Lobster depalletizer can remove bottles using a sweep-type head about 90% of the time, or for reverse tapered bottles, or bottles that should not have shoulder to shoulder contact; the depalletizers can pick and place bottles off the layer and onto the receiving table via inflatable tubes.
The rugged machine construction meets all seismic requirements of California and is capable of responding to new situations. The machine is designed for speeds of 2.5 layers per minute with a pallet and interlayer dimension of 44 inches x 56 inches.
Pallets of bottles that are supplied by OI and Verallia are delivered to the depalletizer via fork truck to the manual pallet undressing area. They are motorized forward on conveyor and positioned for undressing (plastic cover and straps are removed). Operators can move between two platforms at
