9 Claims. 1'
This invention relates to apparatus for tilting drums or barrels during inspection and marking operations and is designed to provide an improved, simplified and easily portable apparatus for ready use at selected stations along a conveyor system.
Heretofore devices used in tumbling drums or barrels for any purpose have formed a fixed and complicated part of the general conveyor system. The mechanism usually included a cradle into which the receptacle to be emptied or otherwise handled must be fitted. The cradle lifting mechanism formed an integral part of the conveyor system and was coordinated to function therewith requiring proper clearance allowances and mechanical coordination for allv movements, This operation was, therefore, confined to one part of the conveyor system and. required a major alteration if it was necessary to. permanently change the locus of this action A temporary change was either not considered or the required movement was accomplished manually. It is an object of this invention to provide an automatic means for inverting, receptacles moved on conveyor systems which is readily portable and operable at any selected point along the path of travel.
This and other objects will be more fully disclosed in the following detailed discussion in which:
Figure 1 is an elevational view' of the device showing operational movement.
Figure 2 is a plan view along lines 2-2 of Figure 1.
Figure 3 is a sectional view of Figure 1 along lines 3-4.
Figure l is an elevational view of an. operating element taken from a partial end view of Figure 1 along lines 4-4.
Referring to the figures of the drawing the rollers of a conventional receptacle conveyor system with which the disclosed device is designed to operate are indicated on Figures 1 and 2 by the numeral It. Channels l2 support the rollers, it in elevated position serving as the movable surface to support and transmit receptacles such as is through the various operations necessary to cleaning, inspection, marking and filling. A receptacle H3 is shown here as a drum. of the type used in the chemical and petroleum. industries. Any other form of receptacle such as a barrel, milk can or the like, too heavy or bulky for easy manual handling, can be substituted. with little or no change in the apparatus presently to be discussed.
The receptacle inverting or device for either temporary or permanent use at selected points along the conveyor system comprises a portable frame generally indicated by the numeral 2d and a gripping and lifting device inclusively numbered 30. The portable frame 20 is of rigid construction and includes a pair of upright members 22 and 24 mounted substantially vertically on a base member 26.
Within the rigid frame 2%) the gripping and lifting device 35 is mounted with the laterally and vertically movable members or arms 32 and 34 spaced to permit the conveyor surface of rollers 50 and the mounting channels l2 to pass therebetween; A transverse vertically movable support 36 slidably engages each of the non-movable members 22 and 24 at its respective ends as shown in Figure 3 and pivotally supports the laterally and vertically movable arms 32 and 34 at the pivots 33 and 49, respectively.
At the upper ends of the movable arms 32 and 34, bearings 42 and 44 are positioned at an elevation above the conveyors movable surface to be adjacent a convenient gripping. area of the receptacle i 4. Gripping shoes 46' and 48 are both pivotally and rotatably mounted in cooperation with the bearings 42 and 44 for flexibility in engaging the receptacle surface and for rotating or tumbling the drum;
The shoe 45, cooperating with the member or arm 32, is pivotally connected at 50, as shown in Figures 1 and 2, to a support 52 which is extended at top and bottom to prevent the shoe 46 from becoming misaligned in operation. In turn the support 52 is fastened to a shaft 54 and responds to all rotary movements thereof.
On the end of the shaft 54 opposite the shoe support 52 a sheave or pulley 56 is fastened. The extended shaft 54, the pulley 56 and the resilient member or spring 58 form the actuated combination of elements which tumble the drum and return it in original position to the conveyor movable surface. The spring 58 is arranged on the shaft 54 and anchored at its endsto be wound into tension when the drum or receptacle i4 is initially inverted. Consideration of Figure 4' together with Figure 1 shows the additional elements required for this operation. A flexible non-stretching means such as a leather or composition belt 60 is riveted to an intermediate adjuster 62 andpartially wrapped"around-the-sheave 56 at the end of which it is fastened as shown. The adjuster 62 is slotted as at 64 and held by a pin clamp 68 in engagement with an anchor piece 68 at proper tension. Both the adjuster 62 and the anchor piece 68' are. roughened at the engaging area to increase the friction between them. The anchor piece 68 is secured to the upright 22 of the rigid frame 20.
Although the rotating or tumbling structure described above could, if necessary, be duplicated to revolve shoe 48 as well as shoe 46, it is not necessary and has been omitted, as illustrated in Figures 1 and 2. This part of the gripping and lifting mechanism is simply the shoe 48, pivoted at m to the support 12 and shaft 14 for flexibility and rotation. It will be noted, as in Figure 1, that both shoes 46 and 48 are made larger in the lower halves in order to gravitationally assist the respective supports 52 and 12 in maintaining them in operating position when disengaged.
Turning now to the lower section of the movable arm 32 and 34, for which reference is made to Figure 1, toggle links 80 and 82 couple them to a fluid operated piston 84. The piston arm 86 is connected to both toggle links at; the pivot 88. The toggle link 88 extends to pivotal engagement with the member 32 at pivot 95 while the same form of structure fastens toggle link 82 and member 34 at pivot point 92. manual operation, usually by the foot of the operator, is connected to a source of pressured fluid not shown which is introduced to conduit H22 through a valve 104.
The preliminary steps necessary in settin up the above described device at a selected station along the conveyor system are both few and simple. The frame complete as described is slipped beneath the conveyor by tilting and then raised to the vertical position with the conveyor track running between the movable arms 32 and 34 as shown in Figure 1. A stand or platform on which the operator works is placed beside the frame and the lever I50 with the valve I54 fastened to it. A hose line from the pressure fluid source required to operate the piston is coupled to the valve and the drum tumbler is ready to operate.
A representative drum I4 is moved between the shoes 46 and 48 when they are in the open position shown by the dot and dash lines in Figure 1. This position is assumed when the piston arm 86 is retracted into the cylinder of the piston 84 drawing the movable arms 32 and 34 inwardly through the movement of the toggle links 80 and 82. The movement of the lower part of the arms being inward, this movement is reversed above the pivotal connections 38 and 40 made with the transverse support 36. The movement of the piston arm 86 being downward, the arms 32 and 34 also move downward as well as the support 35 until stopped by the shoulders on the fixed uprights 22 and 24 obstructing further movement of the support member.
To engage the drum l4 now assumed to be standing between the shoes 46 and 48 on the conveyor, the operator manipulates the lever I08 causing fluid operation of the piston 84. The upward movement of the piston arm 86 moves the arms 32 and 34 laterally about the pivots 38 and 46 causing the shoes 46 and 48 to grip the drum E4 on opposite sides. With the lateral movement stopped by the shoes comin into contact with the drum, any further upward movement of the piston arm 86 lifts the support 36 slidably positioned by the rigid uprights 22 and 24 which lifts the drum clear of the conveyor surface.
The revolving elements as represented by the pulley 56, belt 60 and described anchoring elements now becomes effective by the simple retention of the belt and a rotary motion is im- A lever N20 for parted to the drum through the shaft 54 and shoe 46. The shoe 48 is freely supported and rotates also. At the end of the upward movement the drum has been rotated through 180 degrees bringing the bottom up and tensioning the endanchored spring 58. Full inspection and kindred operation are possible, as well as emptying or other conditioning for which tumbling is required.
With the release of the fluid pressure from the piston, or reverse action if so operated, the initial movement on the descent of the piston arm 86 is to cause the drum to re-rotate back to the original position. Release of tension on the belt 60 and operation. of the spring 58 releasing its tension rotates the drum in reverse from the original rotary motion. The drum is returned to the conveyor surface. The lateral movement of the arm 22 does not adversely affect the tumbling apparatus as the flexible belt 60 remains attached to the sheave 55 and intermediate adjuster 62 and is designed to realign itself for repeated action.
As the drum engages the conveyor surface, the support has reached the lower limit of permitted movement. The drum resists further downward movement and the support pivots 38 and 49 hold the laterally movable arms 32 and 34 against further lowering. The toggles 80 and 82 are still being lowered, however, at the pivot connection 88 but are held at the elevation of pivots 93 and 92. The resultant movement is to retract the lower ends of the arms 32 and 34 thereby releasing the drum M for movement along the conveyor. Successive selection and inversion of drums will follow the same procedure.
