Abstract
A palletizing mechanism (PP, WB, HB-1, HB-2) supplies a pallet and a length of wrapping paper for receiving successive rows of bags until a full pallet load is prepared. The palletizing apparatus can be mated to the bagger apparatus, and operated synchronously therewith under the management of a common programmable controller. The palletizer apparatus receives each stick of can ends in a predetermined orientation, and maintains the orientation vis-a-vis all sticks in a pallet load. The sticks are placed sequentially into a row of predetermined number of sticks, then that row is loaded onto the top of a layer of wrapping, the first row being supported on a suitable empty pallet, then the wrap is passed over the last placed row. This operation proceeds with the wrap supply following a to-and-fromotion until the desired number of rows is automatically built up on a pallet.
Description
METHOD & APPARATUS FOR PALLETIZING
ELONGATED BAGS OF CONTAINER ENDS
Related Applications This application is related to U.S. Provisional Patent Application S.N. 60/060,518 filed 30 September 1997 entitled Bagger & Palletizer for Can Ends, and to copending International Patent Application No. PCT/US98/ (Docket DSG 006 P2) entitled Bagger filed on the same date as this application.
Technical Field This invention relates to methods and apparatus for packaging can ends, e.g. disc-like end units which have a preparatory curl on their edge and which may also have attached easy-open tabs. In practice such apparatus is often called a bagger, since the preferred manner of packaging the ends places a stack (usually called a "stick") of the ends in a tubular bag which is then folded closed at its initially open end. The invention disclosed relates to methods and apparatus for assembling and placing the sticks on pallets.
Background Art In the early 1970s can ends were placed manually into bags, and the bags were loaded manually into pallet for use at filing/~losing machinery. In the mid-1970s semi-automatic bagging equipment was introduced in an effort to keep up with the increased output of newer conversion presses, and that 2,f development led to automatic bagging machines, which were first introduced in the mid-1980s. Some of the impetus for this development was the monotony of repeated manual operations, which also appeared to be the cause of repeated strain to the hands of those doing the bagging.
Those automatic machines formed a "stick" of ends and then packaged them 1) by wrapping them from a coil or reel of paper or plastic, or 2) placing the sticks into preformed bags. It was found that kraft paper was the preferred wrapping material since it can be recycled, and since it will "breathe" to void fumes which may linger with the stick of ends from synthetic sealing compounds applied to the ends in an earlier operation, or to void moisture which may linger from water based compounds.
In the early patent prior art, the disclosures in US patents 3, 337, 064, 3, 417, 853, 3, 545, 631 and 3, 618, 530 are representative of systems which use a pneumatic or similar input conveying system for the individual can ends, and troughs or the like for gathering the ends in a face to face on-edge stack. Mechanical feeding mechanisms engage the curl edges of the generally vertically positioned ends and move them into the input or receiving end of a stack forming in a trough, then the ends are supplied to a filling and closing (end curling) machine.
Wrapping a stack is not disclosed, and the filled trough is intended to function as a reservoir for smooth steady supply of ends to the closing machine.
In US patents 3,722,741, 4,000,709, 4,537,550, 4,676,708 and 5,335,810 more sophisticated buffer systems for stacks of ends are disclosed, wherein the stacks are separated according to a count of stacked ends, and those stacks are loaded into successive vertically arranged carriers on an endless, carrousel type conveyor which supplies the stacks to a closing machine.
US patents 3,878,945, and its various divisions Nos.
3,962,845, 3,971,189, 4,051,965, and US patent 5,119,617, all disclose features of an automatic bagging system in which ends are supplied to a gathering and counting deice which separates ends into stacks (or "sticks"), wrapping devices for loading the stacks into individual bags, and mechanism for loading the wrapped stacks onto pallets.
US patent 4,364 relates to a conveying improvement for gathering ends, providing temporary spacing thereof to facilitate curing of previously applied end seam compound. US patent 4,655,350 discloses an improvement for detecting and removing ends which have been reversed face-to-back (e.g. public to product sides) in the formation of a stack. US patent 4,742,669 discloses and improved end counting device in the end counting and stack forming systems. US patent 5,005,340 discloses a system for inspecting an assembled stack of ends. US patent 5,372,245 discloses an improved drive for an in-feeding array of assembled ends. US patent 5,524,947 discloses an improved mechanism for picking and placing stacks (also called "sticks") of ends in the bagging and palletizing process.
US patents 4,537,010 and 5,372,473 disclose more advanced devices for handling bagged stacks of ends and placing them into pallets.
Thus, prior art automatic bagging machines allow lanes of ends from the output of a conversion press to be counted, separated in stacks or sticks, the stacks placed into individual bags, and the bagged stacks are then loaded into a common palletizer, from which a supply is provided to one or more filling and closing devices.
Disclosure of the Invention A palletizing mechanism supplies a pallet (support) and a length of wrapping paper (usually Kraft paper or the like) for receiving successive rows of bags until a full pallet load is prepared. The palletizing apparatus can be mated to the aforementioned Bagger Apparatus, and operated synchronously therewith under the management of a common programmable controller; an Allen-Bradley Model No. H-4030 is employed in an actual embodiment. The palletizer apparatus receives each stick (closed bag of can ends of predetermined count) in a predetermined orientation, and maintains the orientation vis-a-vis all sticks in a pallet load. The sticks are placed sequentially into a row of predetermined number of sticks, then that row is loaded onto the top of a layer of wrapping, the first row being supported on a suitable empty pallet, then the wrap is passed over the last placed row. This operation proceeds with the wrap supply following a to-and-fro motion until the desired number of rows is automatically built up on a pallet.

Description of the Preferred Embodiment Best Mode for Carrying Out the Invention The present invention is directed to an improved palletizes apparatus which is part of a bagger/palletizer system.
To understand the following description, it is desirable to include first definitions of certain terms, as follows:
A "Stick" is a bag filled with a predetermined number of can ends or lids:
A "Skid" refers to the wooden structure on which a pallet of sticks is built; Filled pallets are formed in the palletizes apparatus:
"Bagger" refers to the portion of the system that forms the sticks by counting ends from the lead (foremost) end in a stream of can ends which are supplied to the bagger apparatus along in-feed rails, the ends being placed on edge and moving face-to-face along such rails; The bagger counts a predetermined number of ends, separates them from the following stream, and places them into a bag, then folds and seals the bag; Sticks are formed in the bagger apparatus, as disclosed in the related International Application PCT/US98/
(Docket DSG 006 P2);.
"Palletizes" refers to the portion of the system that builds layers of filled, sealed bags and places them onto a skid.
The Palletizes The Pick and Place, seen in Fig. 3, removes the filled, sealed bags from the stick discharge grippers of the bagger folding mechanism, and places them on the walking beam mechanism WB (Fig. 4). The walking beam mechanism in turn places each of the sticks in the appropriate position in the staging area. The first (or temporary) hold back device PH-1(Fig. 5), is comprised of three fingers PH-11 which can inhibit the first stick from rolling, and retain the row until the Primary Hold back is reached.
As each stick is placed, the Stick Crowder, also seen in Fig. 6, forces the factory sealed or closed end (against which the ends are pushed in the stick formation) of the bag against a stainless steel place to ensure that each row of the pallet is properly packed.
The Primary Hold back retains the row during building while sticks 8-16 are placed. In conjunction with the Pull Off, the Primary Hold back transfers the completed layer to the Main Table.
Fig. shows the Pull Off, which clamps the row against the Primary Hold back, and transfers the completed layer of the pallet from the staging area to the Main Table.
The Main Table is a movable platform that extends over the pallet and places a completed layer of sticks.
The Skid Storage Lift is the loading point for the empty skids. The X and Y Skid Positioners locate the top skid against the Skid Back Stop.
Figure 11 shows the Skid Shuttle, which contains the Skid trippers that clamp and align the top skid and transport it to the Pallet Zift area.
The Pallet Zift is the hydraulic lift on which the skid is filled with completed layers. The Pallet Zift has a motorized roller table to transport the finished pallet to the Pallet Discharge Roller Table for removal by the operator.
7_ The Row Cut Off, shown in Fig. 13, inhibits the row of sticks from retracting with the Main Table.
The Front and Rear Vertical Tampers, also shown in Figure 2.22, compact the pallet as each new layer is placed.
The Upper Side Guides impose the row offset and retain the layer of sticks as it is placed on the pallet. The Zower Side Guides restrain the palliated layer, and support and compact the new layer being placed.
1. The Snake Wrap Carriage, seen in Figure 20, covers 20 each completed layer with paper after the layer is transferred to the Pallet Zift.
2. The Paper Stuffer (Area 6, Fig. 2) tucks the first layer of paper underneath the cardboard on the skid.
3. The Snake Wrap Paper Cutter cuts the wrap at the completion of the pallet.
The Pallet Discharge Roller Table, shown in Figure 17 is a motorized roller table that moves the completed pallet away from the pallet building area for removal by the operator. This section describes the procedures required to prepare the system for operation. It is divided into two sections; Palletizer and Bagger.
Fig. 20 is a schematic of the Snake Wrap Carriage that shows the proper thread up of the Snake Wrap Roll from the Snake Wrap Catwalk vantage point. Fig. 21 is a pictorial view from the same vantage point.
To load the Snake Wrap roll from the catwalk during system set-up, referring to Fig. 20:
1. Open the Snake Wrap Catwalk door guard.
2. Remove the Split Collar from the Paper Roll Cylinder.
3. Align the Paper Roll such that the paper feeds counterclockwise from the top of the roll.
4. Slide the properly aligned Paper Roll onto the Paper Roll Cylinder.
8_ 5. Replace the Collar.
6. Thread the paper into the pinch rolls ensuring that the paper feeds underneath the tensioning rod prior to the pinch rolls.

3. The Snake Wrap Paper Cutter cuts the wrap at the completion of the pallet.
The Pallet Discharge Roller Table, shown in Figure 17 is a motorized roller table that moves the completed pallet away from the pallet building area for removal by the operator. This section describes the procedures required to prepare the system for operation. It is divided into two sections; Palletizer and Bagger.
Fig. 20 is a schematic of the Snake Wrap Carriage that shows the proper thread up of the Snake Wrap Roll from the Snake Wrap Catwalk vantage point. Fig. 21 is a pictorial view from the same vantage point.
To load the Snake Wrap roll from the catwalk during system set-up, referring to Fig. 20:
1. Open the Snake Wrap Catwalk door guard.
2. Remove the Split Collar from the Paper Roll Cylinder.
3. Align the Paper Roll such that the paper feeds counterclockwise from the top of the roll.
4. Slide the properly aligned Paper Roll onto the Paper Roll Cylinder.
8_ 5. Replace the Collar.
6. Thread the paper into the pinch rolls ensuring that the paper feeds underneath the tensioning rod prior to the pinch rolls.
7. Feed the paper between the stainless steel paper guide and the roller guide.
8. Feed the paper between the spring loaded Paper Clamp and the Roller Guide.
9. Thread the paper through the Slot below the Roller Guide.
[Close all door guards.]
The manually feed the paper by depressing and holding the Snake Wrap Jog push button, being sure to feed a sufficient amount of paper to ensure the Snake Wrap is dispensing properly.
The snake wrap paper is cut with a double-edge, carpet knife blade.
The skid storage lift (Fig. 10) can hold up to 10 empty skids. To load the skids onto the skid storage lift, open the door guard and place the stack of skids onto the left. Then push the stack against the stops at the rearmost and right most positions, and close the door guard.
Prior to homing the Palletizes, it is necessary to ensure that the Skid Storage Lift and Pallet Zift are in the lowest position. It is also necessary to remove all sticks from the Pick & Place, the temporary staging area, and the Main Table, and to remove any partial pallets or empty skids from the pallet lift .
Operating Sequence The pick and place mechanism PP(Fig. 3) removes a stick from the stick discharge of the Bagger apparatus, and places it on the walking beam WB (Fig. 4). Then the walking beam WB places the first stick against the temporary hold back HB-1 (Fig. 5). Those steps are repeated until a complete layer (sixteen sticks) is built. During the building process, the temporary hold back HB-1 9_ and previously placed sticks are pushed progressively farther from walking beam WB as each of the sticks 1--7 are placed.
After the 7th stick is placed, the temporary hold back HB-1 rotates below the level of the sticks, returns to its home position, and the primary hold back HB-2 begins retaining the layer. The primary hold back HB-1 and previously placed sticks continue to be pushed away from the walking beam WB as sticks 8--16 are placed (see Fig. 7).
The row transport RT lowers into position and clamps the completed layer against the primary hold back HB-2. The row transport RT and hold back HB-2 transport the completed layer from the layer building area to the main table MT. The offset cylinder OC (Fig. 8) extends and stops the row transport RT at the appropriate location for the row offset. The main table retainers MTR (Fig. 9) clamp the positioned layer. Then, the row transport RT and hold back HB-2 return to their home position.
Next, the main table MT extends out over the pallet (Fig. 2) and the row cut off RCO lowers. The main table MT then retracts while the row cut off RCO hold the layer of sticks in place.
Effectively they are wiped off the main table onto the top of the load on the pallet. The row supports RS (Fig. 14) restrain the layer after it is positioned, and the row tamp RT (Fig. 13) compacts the layers on the pallet as each layer is placed.
The snake wrap carriage SWC drapes a layer of wrap on top of the completed layer, and waits on the opposite side of the pallet for the next layer to be placed. The row tamp again compacts the layers of the pallet. The foregoing steps are repeated until the pallet is complete, normally when 27 rows are in place.
After completing the last layer of paper wrap, the snake wrap paper cutter WPC cuts the wrap from the roll. The full pallet lift FPZ then lowers to its discharge position. The motorized roller table on the full pallet lift turns on and transports the full pallet to the pallet discharge roller table DRT. It in turn transports the pallet away from the pallet building area to allow the operator to remove the completed pallet. The empty pallet shuttle EPS transports an empty pallet from the empty pallet storage lift to the pallet Zift PL to begin building the next pallet.
While the methods and apparatus for carrying these methods into effect, constitute preferred embodiments of this invention, it is to be understood that the invention is not limited to these precise methods and forms of apparatus, and that changes may be made in either without departing from the scope of the invention, which is defined in the appended claims.
[Close all door guards.]
The manually feed the paper by depressing and holding the Snake Wrap Jog push button, being sure to feed a sufficient amount of paper to ensure the Snake Wrap is dispensing properly.
The snake wrap paper is cut with a double-edge, carpet knife blade.
The skid storage lift (Fig. 10) can hold up to 10 empty skids. To load the skids onto the skid storage lift, open the door guard and place the stack of skids onto the left. Then push the stack against the stops at the rearmost and right most positions, and close the door guard.
Prior to homing the Palletizes, it is necessary to ensure that the Skid Storage Lift and Pallet Zift are in the lowest position. It is also necessary to remove all sticks from the Pick & Place, the temporary staging area, and the Main Table, and to remove any partial pallets or empty skids from the pallet lift .
Operating Sequence The pick and place mechanism PP(Fig. 3) removes a stick from the stick discharge of the Bagger apparatus, and places it on the walking beam WB (Fig. 4). Then the walking beam WB places the first stick against the temporary hold back HB-1 (Fig. 5). Those steps are repeated until a complete layer (sixteen sticks) is built. During the building process, the temporary hold back HB-1 9_ and previously placed sticks are pushed progressively farther from walking beam WB as each of the sticks 1--7 are placed.
After the 7th stick is placed, the temporary hold back HB-1 rotates below the level of the sticks, returns to its home position, and the primary hold back HB-2 begins retaining the layer. The primary hold back HB-1 and previously placed sticks continue to be pushed away from the walking beam WB as sticks 8--16 are placed (see Fig. 7).
The row transport RT lowers into position and clamps the completed layer against the primary hold back HB-2. The row transport RT and hold back HB-2 transport the completed layer from the layer building area to the main table MT. The offset cylinder OC (Fig. 8) extends and stops the row transport RT at the appropriate location for the row offset. The main table retainers MTR (Fig. 9) clamp the positioned layer. Then, the row transport RT and hold back HB-2 return to their home position.
Next, the main table MT extends out over the pallet (Fig. 2) and the row cut off RCO lowers. The main table MT then retracts while the row cut off RCO hold the layer of sticks in place.
Effectively they are wiped off the main table onto the top of the load on the pallet. The row supports RS (Fig. 14) restrain the layer after it is positioned, and the row tamp RT (Fig. 13) compacts the layers on the pallet as each layer is placed.
The snake wrap carriage SWC drapes a layer of wrap on top of the completed layer, and waits on the opposite side of the pallet for the next layer to be placed. The row tamp again compacts the layers of the pallet. The foregoing steps are repeated until the pallet is complete, normally when 27 rows are in place.
After completing the last layer of paper wrap, the snake wrap paper cutter WPC cuts the wrap from the roll. The full pallet lift FPZ then lowers to its discharge position. The motorized roller table on the full pallet lift turns on and transports the full pallet to the pallet discharge roller table DRT. It in turn transports the pallet away from the pallet building area to allow the operator to remove the completed pallet. The empty pallet shuttle EPS transports an empty pallet from the empty pallet storage lift to the pallet Zift PL to begin building the next pallet.
While the methods and apparatus for carrying these methods into effect, constitute preferred embodiments of this invention, it is to be understood that the invention is not limited to these precise methods and forms of apparatus, and that changes may be made in either without departing from the scope of the invention, which is defined in the appended claims.
