Definitions
- ABSTRACT 0F THE DISCLOSURE In a rack of article storage shelves, the inclination of the shelves is changeable from an article feeding position to an article receiving position.
- This invention relates to a storage rack for holding and automatically dispensing similarly shaped articles such as filled bags, cartons or packages.
- the invention is directed to a storage rack having a plurality of vertically spaced parallel shelves inclined to the horizontal and mounted in a frame together with mechanical article feeding and dispensing mechanisms.
- FIGURE 1 is a vertical cross-sectional view through the storage rack of this invention
- FIGURE 2 is an enlarged front view of the links connecting adjacent shelves
- FIGURE 3 is a partial side view of FIGURE 2.
- FIGURE 4 is a front view of the counterweight mechanism for the shelves.
- FIGURE 1 articles on a conveyor belt are attached to be pushed off the belt and fed into the shelf by means of the arm 1 operated in any conventional manner by a motor.
- a crane 2 is mounted on a frame 2a above the storage shelves 2b.
- the crane includes two drums 3 holding the cables 3a which extend vertically.
- the lower ends of the cables are attached to each 3,327,358 Patented .lune 27, 1967 end of a beam 4 by means of gripping claws 5.
- both drums 3 are locked. They are only unlocked in order to change the angle of inclination of the shelves, at which time the drum on the feeding end of the shelf is operated alone. After each shelf is filled, the feeding end of that shelf is lifted with respect -to the stack of shelves and when all of the shelves are filled, the feeding end drum 3 is again locked.
- German Patent No. 1,113,906 discloses that either a stationary lifting apparatus is provided for each stack of shelves or that one or more cranes, depending upon the number of stacks of shelves, are connected to the respective stacks.V In the latter case, the shelves are lowered only if and when another stack of shelves is to be p filled tor discharged. However7 many types of articles or their containers cannot stand the pressure placed on the lower shelves when one hundred shelves filled with articles are lying on top of one another.
- this invention produces the apparatus shown in FIGURE 1.
- the cables 3a do not have the customary hooks but instead each has a gripping claw S joined to a guide tube 6 through which cable 3a extends.
- each tube 6 is telescoped with a cylinder 7 connected to the crane and thus prevents the claws from swinging with a pendulum motion.
- Tracks 8 are mounted on the ends of beam 4 and extend longitudinally through the frame 2a. Claws 5 slidably engage tracks 8.
- Locking members 9 are also mounted on beam 4.
- links 12 are used in which link 12a is composed of a pair of link members and link 12b is a single member pivotally fastened between link members 12a.
- the length of each link member is half the distance between the spaced shelves 2b.
- a stop lug 13 is secured to one or the other of the link members to prevent the links from becoming aligned when the shelves are lifted so that the links will automatically pivot when the shelves are lowered into nested position.
- alternate links are connected to the respective shelves by means of pivot bolts 14.
- the crane in effect can be composed of a counterweighted device not needing operation by a motor, such as an electric motor, or only needing a small power motor. If the articles on a stack of shelves weigh 2O or more tons, to lift and lower the shelves requires a relatively expensive motor driven crane. Such expense is substantially reduced by this invention by using a variable lever held counterweight and needing at most only a small inexpensive motor.
- the crane motor 16 drives drum 3 which holds cable 3a.
- a brake 18 is connected to the drum shaft 20.
- 4the shaft is extended to a conically stepped winch 24 on which is wound the cable 26 holding the counterweight 28.
- the smallest diameter at the apex of the winch is such that the radial lever arm extending from the center of the shaft 20 to the cable 26 will balance out the weight of the unloaded shelves.
- the largest diameter of the winch at the base of the cone is such that the radial lever arm will balance out the weight of the shelves entirely loaded with articles.
- the number of windings on the winch is dependent upon the height at which any number of shelves are lifted.
- the contour of the stepped surface of winch 24 is in the form ⁇ of a parabolic curve.
- the brake 18 is tightened and after each shelf is loaded, the brake is released and the shelf Will drop a distance depending upon the leverage effective on counterweight 28. This distance is the distance to the next empty shelf.
- the brake 18 is then tightened and the unloaded shelfis then fed with articles.
- the brake is released and the shelf will rise to bring the next underneath shelf into unloading position. If any power is required, it is supplied by means of the motor 16.
- a gear train can be installed between the winch 24 and the drum 3 so as to produce a lever ratio of about 1 to 1.5 -to about l to 3.
- a rack for storing similar shaped articles such as filled bags, cartons or packages comprising a frame, a plurality of vertically spaced parallel shelves mounted in said frame inclined to the horizontal, and means for lifting and lowering said shelves, the improvement in which said means for 4lifting and lowering said shelves comprising beam means joined to said shelves, crane means movably mounted on said frame and detachably joined to said beam means for changing the angle of inclination of said shelves, and means ⁇ for locking said beam means in lifted position to said frame so that said crane means can be detached from said beam means.
- said beam means further comprising tracks
- said lifting and lowering means further comprising cables joined to said crane means, and gripping claws secured to said cables and slidably engaged with said tracks.
- said lin-ks further comprising a single link member pivotally joined between a pair of link members, and stop means secured to said 4links for preventing the single member from being aligned with said pair of members.
- said crane means further comprising a counterweight, and variable lever means joined to said counterweight and to said cables for-producing a lever ratio of from about 1 to 1.5 to about 1 to 3 permitting movement of said beam means 4and said shelves without motor power.
