AUTOMATIC STOP FOR TAKE-UP BLOCKS Filed June 50, 1937 2 Sheets-Sheet 2 FIG. 3. 0 I: fix o Patented Nov. 8, 1938 UNITED STATES AUTOMATIGSTOP FOR TAKE-UP BLOCKS Edward F. Schuman, Garfield Heights, Ohio, assignor to The American Steel and Wire Company of New Jersey, a corporation of New Jersey I Application June 30,
2 Claims.
The present invention relates to an automatic stop for take-up blocks.
In the treatment of coils of narrow strip steel, it is usually fed through a coating bath and then into a heating furnace where the coating is baked on the strip. After sufii'cient baking, the strip enters a cooling zone where the temperature is re-- duced in order to make manual handling of the strip possible, after which the strip passes through constant speed pull-out rolls and is vibrated onto take-up blocks. I
When it is desired to make such a process continuous it is necessary to attach the end of one coil to the beginning of another. This is done by lapping the ends of the strips and spot welding the lapped portions.
However, it is necessary to cut out the welded portion of the strip before it is wound upon the take-up blocks, and provision must be made to stop rotation of each take-up block until the double thickness of metal formed by the welding operation has been cut out of the strip.
An object of the present invention relates to a mechanism for automatically stopping rotation of the take-up blocks as the weld approaches the same for winding thereon.
A further object is to provide a device which is actuated by the welded portion of the strip to disengage the clutch from each individual takeup block and stop rotation thereof until the welded portion has been removed from the strip.
Other objects and advantages will become apparent as the description proceeds, in which:
Figure l is a plan of a section of the take-up block frame showing how the automatic stop mechanism is applied thereto;
Figure 2 is a side elevation of Figure 1, showing the position assumed by the automatic stop when the take-up block is running;
Figure 3 is a similar view to Figure 2 but showing the position assumed by the mechanism when the take-up block has been stopped;
Figure 4 is an enlarged detailed section on line IVIV of Figure 2; and,
Figure 5 is an enlarged detailed section on line VV of Figure 2.
In the drawings, the numeral 2 represents the take-up frame upon which is supported a plurality of take-up blocks 3. For the purpose of illustration, the drawings show only a section of the entire take-up block frame. However, it is to be expressly understood that each individual takeup block upon the take-up frame has an automatic stop mechanism identical to that shown in the drawings.
1937, Serial No. 151,285
Extending from each take-up block is a shaft 4 on the end of which is mounted a clutch-housing 5 for receiving a clutch 6 carried on the end of the drive-shaft 1, the latter shaft for each take-up block being simultaneously driven in any conventional manner (not shown).
Secured to each clutch 6 is a clutch-lever 8 having pivotally connected thereto a lever. 9 which extends transversely of the take-up frame and parallel to the shafts 4 and 1. Each lever B is provided with projections ID to which are secured the ends of springs l2, while the other ends of said springs are secured, in any desired manner, to the take-up frame 2. The take-up frame is provided with plates 13 having slots It through which the levers 9 pass.
Each of the levers 9 is provided with a slot or, if desired, an extension l5 which engages a pivoted catch I6 and maintains the levers 9 in the position shown in full lines in Figure 1 so that the clutch-levers 8 maintain the clutch 6 in engagement with the clutch-housing for rotating the take-up blocks 3. The ends of the levers 9 are provided with a hand-grip I! in order that the levers may be restored to their full line position after the automatic stop has disengaged the clutch and stopped the rotation of the take-up blocks.
A supporting-plate I8 is secured to the take-up frame 2 and pivotally carried by said supportingplate is a tripping lever l9 which includes laterally extending spaced arms 20 between which the strips are adapted to pass. Secured to each of the arms 20 and adjustably mounted thereon are plates 2|. Pivotally secured to an extension 22 of the trip lever I9 is a connecting link 23, said link being pivotally connected, at its other end, to the catch IS. A spring 24 connected to the lever 23 and to the supporting-plate l8 returns the tripping lever l9 and catch Hi to their operating position after they have been tripped and released by the weld on the strip material.
In the continuous process of treating strips, the ends of the strips are lapped and spot welded. Before the strip material can be wound upon the take-up blocks it is necessary to cut out the welded portion and, as each welded portion is removed from the strip, means must be provided to stop each individual take-up block until the operator has completed this operation. Under the present invention, as the double thickness of metal formed by the welding of the overlapped ends approaches the individual take-up blocks it engages the trip lever I9. The plates 2| having been previously adjusted to limit the space to less than the double thickness of metal caused by the welding of the ends together, results in a movement of the tripping lever I9, of each take-up block, in the direc tion of the travel of the strip. In so doing, downward movement is imparted to the lever 23 and, due to its pivotal connection with the catch I6, causes an upward movement of the catch I6. This releases the lever 9 and, in so doing, permits the springs I2 to move the lever 9 to the position shown in the dotted lines in Figure 1. Such a movement of lever 9 carries the clutch-lever 8 to the dotted line position shown in Figure l, and thereby disengages the clutch from its clutchhousing and stops rotation of the individual take-' up blocks 3. After the weld has been cut out from the strip, the coil banded and removed from the take-up block, the end of the new coil is threaded through the plates 2 i 'and'takeuip block 3. The operator, by grasping the handle I1, is enabled to restore the lever B to its full line position shown in Figure 1 and, in so doing, the catch I6, through pressure of the springs 24", engages in the slot or projection l5 on the lever 9 and holds the clutch in operating position for rotating the take-up blocks 3 until again released by the next succeeding weld on the strip or, if desired, at any time desired by the operator.
While I have shown and described one specific embodiment of my invention, it will be seen that 'I do not wish to be limited exactly thereto, since various modifications may be made without de parting from the scope of the invention, as defined by the following claims.
