Description
AUTOMATED COLUMN FOR WORK IN PROCESS BUFFER
The present invention relates to a buffer for manufacturing purposes, in which works in process, hereinafter called WIP, are stacked one upon the other, so that a LIFO queuing method can be actuated.
A hollow column houses an upright array of shelves uniformly arranged therein and, then, a set of said columns, linked one another by suitable rods, is used to build the whole buffer. In said buffer hollow column the shelves are mounted such that each one can rotate around its own horizontal axis, from a closed upright position to an open horizontally-extended position, allowing for stacking a WIP. The first WIP is stored at the lowest shelf, which is, for a given arrangement of the shelves, in its open horizontally-extended position, whilst, the next upper shelf is at an intermediate position, between the closed upright position and the open horizontally-extended position, waiting for the next WIP to be stored. The second upper shelf and the subsequent shelves are all closed in order to let the WIP to be stored pass toward the first free shelf, in this case being the second upper shelf.
These buffers are just known in the art and mainly used in the automotive industry, but nowadays a chance to increase the amount of the WIP to be stored is needed while maintaining the current maximum height of said buffer columns. As a result, the only way to achieve the above object is to reduce the pitch between shelves. EP 1 505 010, owned by the Applicant of the present invention, and the documents therein cited, such as EP 0 613 837, DE 29906366 U, DE 20307164 U, EP 0 878 416, disclose storage structures with different kinematic chains, for sequentially moving the shelves, being not able to reduce pitch between two subsequent shelves under certain values, which results the only way to increase the number of said shelves and, consequently, the storage size of the buffer under the same bulk conditions. The limit for maximum height of these buffers arises from the
truck trailer storage capabilities, when a WIP stock has to be delivered to another manufacturer for a further production step. The buffer height, obviously, has to be under the maximum height of the truck trailer, which is a safety value fixed by the transportation authorities in each country, in order to arrange the WIP loaded buffer inside the truck trailer. Thus, the only way to reduce the delivery costs is by increasing the WIP amount per trailer, object which is accomplished by a shelf pitch reduction. In addition, the increasing use of automated handling system, in place of the manual handle of the WIPs, does not require high pitch values anymore, since a robot end- effector, generally, needs a 50 mm shelf pitch, at most.
The main object of the present invention is, therefore, to provide a column-based buffer in which the overall dimensions of the kinematic chain adopted are smaller than the overall dimensions of the prior art kinematic chains. Depending on the configuration selected for the kinematic chain of the present invention, there will be a chance to achieve a pitch between two subsequent shelves of 20 mm or even less.
Another object of the present invention is to provide a column-based buffer in which the overall dimensions of the columns are reduced once the overall dimensions of the kinematic chain adopted is smaller.
Another object of the present invention is to provide a column-based buffer in which the kinematic chain can be mounted either inside or outside the column, which results in a more flexible and cost-effective assembly process, since it is separate for the shelves and for the counterweights used. Moreover, a separate assembly process results in faster and less expensive operations of extraordinary maintenance necessary, for example, to replace one or more broken column parts. In the prior art buffers, on the contrary, maintenance operations require the column to be entirely disassembled.
A further object of the buffer according to the present invention is to provide an increased space inside said columns in order to allow for housing additional useful devices.
The features and advantages of the column-based buffer according to some preferred embodiments of the present invention will be described in detail within the following specification and the annexed set of drawings, in which like referral numbers are used to indicate similar elements and in which: fig. 1 is a perspective view of an assembled column of the whole buffer and an enlarged view of an innovative slot according to a first preferred embodiment of the present invention; fig. 2 is a exploded perspective view of the column in fig. 1; fig. 3 is a perspective view of some lower shelves including the first shelf of the column in fig. 2; fig. 4 is a perspective view opposite to the perspective view in fig. 3; fig. 5 is a perspective view of the kinematic chain part according to the present invention; fig. 6 is a perspective view of the shelves according to a second embodiment of the present invention; fig. 7 is a perspective view of the shelves according to a third embodiment of the present invention; fig. 8 is a perspective view of shelves able to house more than one WIP for each shelf; and fig. 9 is a perspective view of fittings mountable on the shelf according to the present invention allowing for fragile WIP storage such as, for example, a windshield. Referring now to fig. 1 and 2, the column body 10 is built by connecting to a shoulder slab
12, along each longer side thereof, a sidewall slab 11 thus forming an hollow profile, which is then connected to a base slab 13. Said base slab 13 is provided with four slots 13a at each comer thereof in order to allow the assembly of the column body 10 on the base (not shown) of the whole buffer. The pair of the sidewall slabs 11 and the shoulder slab 12 are provided, respectively, with holes 11 a and 12a for assembly purposes, as well.
As shown in fig. 2, a pair of metal sections 20 can be mounted on the above column body 10 by means of holes 11b provided on the sidewalls 21 of each steel section 20 and corresponding to said holes 11a, and holes 12b on the shoulder 22 of each steel section 20 and corresponding to said holes 12a. Each metal section 20 is shaped so that a housing space between a sidewall 21 and the opposing sidewall slab 11 can be obtained. Each sidewall 21 is also provided with an array of slots 21a thus forming pairs of slots 21a facing each other and allowing for the shelf assembly inside the column. Each slot 21a is circular shaped but integral with two diametrically opposed stops 21a1.
As shown in fig. 3, a single shelf 30 is constituted by a small plate provided at its rear end with a pair of squared-section winglets 31 adapted to engage the pair of slots 21a on said sidewalls 21. As shown in fig. 2, since the slots have the above stops 21a1 suitably disposed, the shelf 30 can rotate around the horizontal winglet axis for about ninety degrees, that is till the winglets 31 reach the stops 21a'. In such a manner, the stops 21a' serve as top dead center and bottom dead center of the shelf. In the preferred embodiment, the lowest shelf, which is the first to be loaded, engages by its winglets 31 a pair of slots 21a having wider stops 21a1, which results in a shorter circular stroke of the first shelf with the same bottom dead center and a lower top dead center allowing for an intermediate position of the first shelf, once unloaded. The shelf 30 at its rear end is also provided with a inclined plane 32 integral with a squared-section pin 33 at its right side . Fig.4 shows a cam 40 engaging said pin 33 by means of a squared hole 33a. As shown in fig. 5, a counterweight 50 is provided with a squared-section hole 50a adapted to engage a winglet 31. Said counterweight 50 is arranged inside the housing space between a sidewall 21 and the facing sidewall slab 11.
Depending on the particular pitch and/or bulk needs, different configurations and sizes of the counterweight 50 are allowable. In the preferred embodiment, by which the minimum pitch is achieved, each shelf 30 is engaged with only one counterweight 50, in turn from the bottom to the
top of the column, on the left-side winglet 31 and on the right-side winglet 31; this counterweight arrangement allows for the minimum pitch achievable for the given size and shape of the counterweight 50.
Still referring to fig. 5, the profile of the counterweight 50 is shaped so that, while a shelf rotating around winglet horizontal axis, it will not bump against any part of the column including shelves, the other counterweights, winglets and the like, and, also, it will have a center of gravity far enough from the winglet axis to apply a suitable righting moment on the shelf 30, once unloaded.
The aforementioned cam 40 represents the main feature of the present invention, since it causes the outwardly rotation of the first unloaded upper shelf 30 when the last loaded shelf 30 is going to reach the horizontally-extended position due to the WIP load. Thus, the first unloaded upper shelf 30 moves, being pushed on its cam 40 by the cam 40 of the next lower shelf 30, from the upright position to the intermediate position, in which the first unloaded shelf 30 is inclined for about forty five degrees and it is able to receive the next WIP to be stored. In the above embodiment according to the present invention a kinematic chain, comprising the set of cams 40 for the opening shelf movement, driven by the WIP loading, and the set of counterweights 50 for the closing shelf movement, driven by the counterweight mass, is provided for a complete automation mechanism of the column and, therefore, of the whole buffer.
Different shapes and fittings are also provided for the shelves 30 and shown in figs. 6 and 7. Depending on the shape of the WIP to be handled, the supporting portion of the shelf 30 can be designed to suit the WIP shape and, consequently, to prevent the WIP from being damaged, once laid by the robot end-effector on the shelf. In fig. 6, for example, a shelf for an upwardly concave WIP is shown.
Generally, the horizontal positioning of the WIP is assured by the main body 10 of the column, so imposing a very narrow tolerance range for the column relative positions, for which
reason the adjusting slots 13a have been provided. In order to overcome the above disadvantage, a further embodiment of the shelf 30 according to the present invention may provide a WIP stop 60 formed on the supporting portion of the shelf 30 and integral therewith. The stops 60 operate to leave a larger side clearance for handling and positioning WIPs, since the relative positions between columns in the whole buffer have not to be so accurate anymore and, also, to prevent the WIPs from interfering with any parts of the automated column. The stop 60 can be, for example, obtained by cutting an inner portion of the shelf supporting portion and, then, bending it upward, as shown in fig. 7. This stop arrangement allows the shelves to reach their upright position, in which each stop 60 engages the hollow portion 60a of the next upper shelf 30.
Referring now to fig. 8, an improved shelf is shown, including two different portions: a shelf frame 34 and a supporting shelf 32 pivotally mounted on said shelf frame 34, so that the supporting shelf 32 can rotate around an axis defined by a pair of planar hinges 35. This shelf arrangement allows for housing more than one WIP on each shelf, since the vertical space between two subsequent shelves is increased by the rotation of the upper supporting shelf 32.
In fig. 9 fittings 70 is provided to prevent fragile WIP from being damaged, such as windshields or other glass products; the shelf 30, in this case, needs to be provided with at least one snap-fit type engagement 71 able to engage a corresponding hole 72 on the fittings 70, in order to secure the fittings 70 onto the shelf 30. If a fittings replacement is needed due to a wear phenomenon, the fittings 70 can be removed by a fast cutting operation, since it is generally made of such a sufficiently soft plastic material as to allow use of a simple cutting tool.
Other embodiments according to the present invention can be realized with different arrangements of the counterweights 50: they may be arranged, for example, on only one side of the column housing space in order to further decrease the whole column bulk, if needed. The automated column for work in process buffer according to the present invention has been
described, referring to the preferred embodiment, just in an illustrative but not limiting way, and to show its essential features. It is intended that numerous variations could be made to said automated column according to the industrial, commercial and other necessities, as well as other systems and means could be included, even without falling outside its scope of protection.
