Application filed September 21, 1925. Serial No. 57,784.
This invention relates to a new and improved roll table and more particularly, to a roll table provided with means for assembling billets in a desired relation.
In connection with shears or the like, it is often desirable to assemble the billets, leaving the shears, into groups for passing them along for further handling. This minimizes the labor and also avoids the diflito culty that short billets may get/crosswise of the roll table.
It is an object of the present invention to provide a roll table adapted to assemble billets in groups and permit their discharge is from the table in assembled groups.
It is an additional object to provide a table of this character which automatically moves the billets received upon the table laterally against a stop or against an adja- E cent billet.
Other and further objects will appear as the description proceeds.
I vhave illustrated a preferred embodiment of my invention in the accompanying draw- 25 ings, in which Figure 1 is a plan view of a table constructed according to the present invention;
Figure 2 is a section taken on line 2-2 of Figure 1, and
Figure 3 is a transverse section taken on line 3--3 of Figure 1.
The roll table comprises the supporting frame members 11 and 12 and the transversely extending fiat table members 13. The cylindrical rollers 14 are carried by the side frames and are provided on one end with the beveled gears 15 meshing with similar gears 16 on the drive shaft 17. This shaft 17 is driven through a suitable reduction gear assembly 18 by the motor 19. As shown in Figure 1, skids 20 are provided extending laterally from one side of the roll table, so that the billets may be removed laterally as desired. 7
The table is provided with a plurality of helical rollers 21 which are similarly driven from drive shaft 17 through beveled gears 22. One of these rollers is shown in section in Figure 3 and it will be noted that the helical outer surface is provided with the long, gradually inclined slope 23 which inclines towards the center of-the roller and the short, somewhat abrupt slopes 24 between adjacent turns of the helical surface 23. The center bar 25 is sugporte'd upon the members 26 secured to the at table portions 13 and extends longitudinally of the table.
Referring now particularly to Figure 2, the stop member 27 is supported in the guide ways 28 and extends transversely the full width of the roll table just beyond the end of the center bar 25. This stop 27 is con nected by link 29 to one end of the bell crank lever 30. The opposite end of the lever 30 is connected to the piston rod 31 which is carried in the two cylinders 32 and 33. An additional pair of stops 34 are provided, one located upon each side of the center bar 25. Each stop 34 is directly connected to the pin 35 which is fixedly secured to a piston 36 operating in cylinders 37 and This construction may be used with any type of apparatus delivering billets or the like where it is desired to group them for further handling. It is of particular utility in connection with a duplex shear, the roll tables of which would deliver billet-s to the right end of the table of the present invention, as shown in Figure 1. Billets would be delivered upon each side of the center bar and adjacent the outer edges of the table. It will be understood that all of the rollers 14 and 21 will be rotated in the counterclockwise direction as seen in Figure 2, so as to carry the billets to the left.
It will be apparent from Figure 1 that during this rotation the portion of the helical surface of rollers 14 which engages a billet will continuously move towards the center bar. This will have the effect of moving the billets toward the center bar. Consequently, the billets will be brought against the center bar before they pass beyond its end and will be properly lined up longitudinally of the table and passed on to the central portion of the table beyond the center bar and properly directed.
If it is desired to assemble billets on both sides of the bar into a group for further delivery, the stop 27 is raised by admitting fluid under pressure to the cylinder 33. The first billets will be moved against the center bar and succeeding billets will be moved against the previously centered billets until the width of the table is occupied. The stop 27 is then dropped by admitting fluid into the cylinder 32. The assembled billets then move forward as a group for further handling.
If it is desired to assemble a group on either side of the center bar, the desired stop 34 only may be lifted, the other stop remaining down. It may be desirable in some cases'when handling shorter billets to raise the stops 34 and assemble the billets. and then pass them on to stop 27 to be held there as long as desired. The centering rolls and the plurality of stops allow considerable flexibility in the handling of billets with a minimum of labor and without center bar, I I
I have shown one preferred form of my invention by way of illustration, but it is to be understood that I contemplate such changes and modifications as come within the spirit and scope of the appended claims. I claim 1. In a roll table, means adapted to deliver billets to the table, a stop adapted to be interposed in the path of the billets to limit their forward movement, a center bar on said table, and means adapted to automatically move the billets laterally of the table from each side toward said center bar.
2. In a roll table, means adapted to deliver billetsiadjacent the longitudinal ed es of-the table, means adapted to automatically move the billets toward the center of the table, and a fixed bar extending longitudinally of the center of the table.
3. In a roll table means adapted to de liver billets to the ta le, a center bar on said table, and helical raised portions on certain of the rollers adapted to urge the billets laterally of the table from each side against said center bar. I
4; In a roll table, means adapted to deliver billetsto the table, a center bar on said table, and helical raised portions on certain of the rollers adapted to urge the billets laterally of the table ainst said center bar, the hehcal raised portions being upon such an angle as to prevent pinching of the billets I against the center bar.
