- FIG. 7 GUIDE MECHANISM FOR PACKAGING MACHINE Filed Dec. 10, 1969 6 Sheets-Sheet 6 INVENTOR. ROBERT E. RADEMACH-ER ATTORNEY FIG. 7
- a guide mechanism for said apparatus which comprises opposed guide members, means pivotally mounting said guide members for movement towards and away from the packaging station, means modifying said pivotal mounting means such that movement of the guide member tips towards each other is limited during the movement of the guide members towards and away from the packaging station.
- This invention relates to the packaging of articles and more particularly to apparatus for bagging narrow articles.
- Bagging apparatus generally include means for inflating the topmost bag of a bag supply, at least one pusher bar and a pair of opposed members that form a guide through which the pusher bars push an article into the inflated bag.
- These guide members are pivotally mounted and are operated between two positions, a closed position where the guide members are pivoted inwardly toward each other to present a narrow profile for entry into the inflated bag and an open position where the guide members engage the sides of a bag and hold it open while the pusher bar pushes the article into the bag.
- the bag supply is commonly mounted in front of and at a lower level than the guide members and thus there are two criteria for the pivotal movement that have to be met, the fronts of the guide members must be retracted far enough in their inwardmost position to permit the bag to rise in front of the guide members and they must be advanced enough in their outwardmost position to allow a suificient portion of the guide members to enter the bag to grip it and hold it open for the entry of an article therein.
- the guides of packaging machines of the class described are mounted for relative lateral movement to provide a capability for bagging a variety of article widths.
- a simple pivotal movement of the guide members suffices for a wide variety of shapes and sizes of bags, since a simple pivotal movement will retract and advance the guide member tips to allow for the bags to rise and be engaged.
- the guide members are mounted so close to each other that a simple pivotal movement does not provide the required longitudinal movement of the guide members necessary to meet the two criteria set forth hereinabove. Either there will be an inward pivot insuflicient to retract the guide tips to allow the bag to rise, or there will be an insufficient outward pivot to enable the guide members to engage the bag.
- apparatus may comprise a guide means for a packaging machine, which comprises a pair of opposed members, means mounting said members for pivotal movement toward and away from each other, and means for modifying said pivotal movement to elfect limited lateral movement of the guide member tips.
- FIG. 1 is a plan view of a packaging machine including the invention.
- FIG. 2 is a front elevation view of the machine shown in FIG. 1 with a portion thereof broken away to depict parts of the operating mechanism thereof.
- FIG. 3 is a side elevation view of the machine shown in FIGS. 1 and 2 with a portion thereof broken away to show features of the operating mechanism of the machine.
- FIG. 4 is a plan view of a guide mechanism according to the invention.
- FIG. 5 is a side elevation view of the guide mechanism.
- FIG. 6 is a sectional view of the guide mechanism taken along line 6-6 of FIG. 5.
- FIG. 7 is a plan View of the guide mechanism showing an adjustment for a different sized bag.
- the machine specifically described in the aforesaid co-pending application, Ser. No. 763,100 includes a conveyor 10 (the numbers ascribed to the various parts of the packaging machine are not the same as those in the co-pending application) for transporting articles to a transfer station 12 opposite a supply subcombination 14 that is operable to provide an open bag in spaced relationship to the transfer position.
- a plurality of pusher bars 18 are mounted in housing 20 and driven such that they engage articles at the transfer position, push them over a dead plate 22, through a guide mechanism 24 and insert them into the open bag. The pushers push the article against the back of the bag and thus remove the bag from the supply and the guide mechanism whereupon the bagged article falls on an outfeed conveyor 26 that transports it to a collection area.
- conveyor 10 shown and claimed in the aforementioned co-pending application is a variable flight conveyor
- guide mechanism of the instant invention is operable in an environment with any conveyor that moves articles to the transfer position.
- the supply subcombination 14 includes, briefly, at least one tray 28 slidably mounted on a support 30 such that it may be precisely positioned with respect to the transfer position, the guide mechanism and the path of the pusher bars.
- the tray is adapted to receive a wicket of bags (not shown), each held therein by an extending lip that forms part of the bag, as disclosed in detail in said application Ser. No. 620,387.
- a jet (not shown) connected to a source of compressed air is mounted adjacent the tray 28 to inflate the topmost bag when an article is detected approaching the transfer position by a photocell 32.
- the tray is mounted below the guide mechanism, but when the topmost bag is inflated it rises such that at least a substantial portion of the mouth of the bag is in spaced relationship with the guide mechanism.
- a guide mechanism 24 includes a pair of opposed guide members 34 and 36 respectively, one mounted on each side of the path of the pusher bars 18.
- a channel shaped mounting bracket 38 is secured to each of the guide members, as by bolts 40 (FIGS. 6 and 7).
- the guide members are movable between their outward position, shown in solid lines in FIG. 4 and their inward position, shown in dotted lines by a linkage 42 connected to the lower flange of the respective mounting brackets.
- the linkage 42 connected to each of the guide members includes a primary pivoting arm 44 connected to the rear of the lower flange of the brackets 38 at 46 and a secondary pivoting arm 48 pivotally connected to the front of the brackets 38 at 50.
- the other ends of each of the primary pivoting arms 44 are connected to the top of a vertically extending shaft 52 by a wing tip nut 54.
- the other ends of each of the secondary pivoting arms 48 includes an eyelet 56 which is mounted over the top of a vertically extending pivot post 58, with a wing tip nut 60 provided to secure the arm thereon for pivotal movement.
- the shafts 52 are mounted for pivotal movement in sleeve-like supports 62 and the pivot posts 58 are mounted to the supports 62 by a horizontally extending bracket 64.
- the action of the secondary arms does not affect the rearward movement, the longitudinal element of the movement of the guide members, but does affect the inward movement of the guide members tips, the lateral element of the guide member movement, limiting the amplitude of the inward movement of the guide members due to the fixed location of the eyelets 56 and the length of the secondary arm.
- the eyelets 56 are, in effect, second pivot points that pivot the tips of the guide members outwardly as the pivoting of the primary arms around shafts 52 pivot the rears thereof inwardly.
- the shafts 52 are rotated in the same manner as the corresponding shafts in the aforesaid co-pending application Ser. No. 763,100, that is by levers 66 connected to the bottoms thereof.
- the levers are connected to an actuating bar 68 by fork shaped connectors 70.
- the guide members are pivoted inwardly by forward movement of the actuating bar 68. This is effected by a bell crank 72 connected to the actuating bar at 74 and pivotally mounted to the machine frame at 76.
- the bell crank is rocked by a rod 78 connected at one end thereof to the bell crank at 80 and at the other end thereof to a cam follower 82.
- the cam follower 82 is pivotally mounted at the center thereof to a bracket 84 by a pin 86 and includes a cam follower wheel 88 that rides on a cam 90 mounted on the output shaft 92 of a gear reduction unit 94.
- cam 90 allows cam follower wheel 88 to be pulled upward and thus causes rod 78 to pivot bell crank 72 in a clockwise direction as seen in FIG. 3, the forward end of the guide members 34 and 36 are pivoted to their inward most position whereat the forward ends thereof are behind the front of dead plate 22.
- cam follower wheel 88 rides up on cam 90, cam follower 82 pulls rod 78 up and thus pivots bell crank member 72 in a counterclockwise direction, pivoting the guide members 34 and 36 outwardly. This outward pivotal movement results in the forward movement of the guide members into the open bag to hold the bag open for the reception of an article pushed therein by a pusher bar 18.
- the spacing between the guide members is adjustable for different package (bag) widths in the same manner as the guide members in the aforesaid co-pending application Ser. No. 763,100.
- each of the secondary pivot arms comprises a sleeve member 100 that is bored and tapped at both ends for threadedly receiving a connecting eyelet member at each end.
- the eyelet members designated 102 and 104 respectively can thus be rotated in the sleeve member 100 to change the length of the secondary pivot arm.
- the secondary pivoting arms have been made longer with comparison to those shown in FIG. 4. This results in a shorter distance between the guide member tips than that shown in FIG. 4 when the shafts 52 rotate the guide members to their outwardmost position.
- the sides of a narrower bag would be engaged and held open by the guide members than the arrangement shown in FIG. 4.
- each of the guide members 34 and 36 comprise an inner plate 106 and an outer, shaped, scoop member 108.
- the inner plate and the outer scoop member are joined together to the brackets 38 by the bolts 40.
- the outer scoop members include slots 110 in the area where they receive the bolts, such that they may be raised with respect to the inner plate and bracket.
- Both the inner plate and the outer scoop members are flared outwardly at 112, the rear portion thereof, to effect a funnel arrangement for articles being moved therethrough from the transfer position by the pusher bars and which may be off centered.
- the guide members are adjustable for different shapes and sizes of narrow articles. It is, however, the linkages 44 that make the packaging a range of narrow articles possible since without the modification of guide movement effected thereby, the type of apparatus disclosed would not successfully operate.
- Guide means for a packaging machine which comprises:
- linkage means connected between each of the members and a respective remote fixed anchor for modifying said pivotal movement to effect limited lateral movement of the guide member tips.
- each of said guide members includes inner and outer plates that are movable with respect to each other to adapt the guide members to various size articles.
- the means mounting the guide members for pivotal movement includes a first arm connected to each guide member and means for pivoting said first arms, and
- the linkage means for modifying the pivotal movement includes a second arm pivotally mounted to each of the guide members at a point spaced from the connection of the first arm thereto and pivotally mounted to its respective remote anchor at its other end,
- a guide mechanism according to claim ,1, wherein said means pivotally mounting said guide members includes:
- a guide mechanism according to claim 4, wherein said means for modifying said pivotal movement includes:
- each of the linkage means for modifying the pivotal movement includes a second arm pivotally mounted to each of the guide members at a point spaced from the connection of the pivoting arm thereto, the second arms being pivotally mounted at their other end to the respective remote anchors,
- a guide mechanism for said apparatus which comprises:
- linkage means mounted between each of the guide members and a respective remote fixed anchor for the operation of said pivotal mounting means such that movement of the guide member tips towards each other is limited during the movement of the guide members towards and away from the packaging station.
- said guide members include inner and outer plates that are movable with respect to each other to adapt the guide members to various size articles.
- the means mounting the guide members for pivotal movement includes a first arm connected to each guide member and means for pivoting said first arms, and
- the linkage means for modifying the pivotally mounted to each of the guide members at a point spaced from the connection of the first arm thereto and pivotally mounted to its respective remote anchor at its other end, the first and second arms thus forming a parallel linkage.
