  • a path 8 for receiving creel trucks loaded with empty bobbins.
  • Turn tables 10, 11 are disposed on a path connecting the paths 8 and 9 in a position corresponding to the truck paths 2 of the drawing machine.
  • Numeral 6a is a hand rail and numeral 6b is a stopper.
  • Guide rails may be mounted on the stand-by platform to facilitate the movement of the creel trucks.
  • the length of the standby platform is preferably the same as that of the drawing machine 1 itself but, if impossible, the width of the platform should be wide enough to arrange desired creel trucks in a plurality of rows.
  • the undrawn yarn packages 100 are placed on the creel trucks 4 in the carriages 3 and carried near the drawing machine in the drawing chamber.
  • the carriages 3 are arranged near the end of the stand-by plat form 6.
  • two creel trucks 4 together with the carriage 3 are lifted and carried to one end of the stand-by platform 6 with the use of the forklift truck 5.
  • the fork is hoisted to cause the upper creel truck to reach the level of the stand-by platform 6.
  • the creel truck is pushed out onto the stand-by path of the platform 6 by an operator on the step 505 of the forklift truck.
  • the fork is raised to lift the lower creel truck to the level of platform 6 and put it on the stand-by path 9 of the platform 6 by the same procedure as before. Then the fork is lowered to pick up another carriage 3 loaded with two creel trucks 4. The cycle is repeated. After the creel trucks have been pushed out on the stand-by path 9 of the platform, the forklift truck is moved without lowering the fork from the path 9 for full creel trucks to the path 8 for empty creel trucks, pulling an empty creel truck on the path 8 into the lower step of the emptied carriage 3, lower ing the fork receiving another empty creel truck on the upper step of the carriage 3 and finally lowering the fork to the floor. Thus with one lifting and lowering operation two full creel trucks are lifted and two empty creel trucks are lowered.
  • a stand-by platform is arranged adjacent the truck paths above the drawing machines and a stand-by path for full creel trucks and an exit path for empty creel trucks are juxtaposed on the platform to cause a forklift truck to supply full creel trucks onto the stand-by platform and to discharge empty creel trucks from the platform at the same time.
  • the number of creel trucks to be received by the stand-by platform is equal to that which can just cover one drawing machine, and the above-mentioned replenishing of creel trucks can be conducted for only one drawing machine at a time. Therefore undrawn yarn package replenishing time for each drawing machine is to be staggered. This is easily done by determining appropriately working hours for each drawing machine.
  • the wire 204 is wound with the winch 206, and the hook 205 is kept on the block 207.
  • the first creel truck is led to the truck path 2 such that the hook 205 on the block 207 catches the base frame of the first creel truck.
  • the winch 206 and the drum 206a are disconnected to let the drum rotate freely. Subsequent creel trucks are pushed in one by one and the desired number of creel trucks is set into a creel (The top creel truck is engaged with a stopper 202). Since the path 9 runs perpendicularly to the truck path 2, each creel truck is to change its direction on the turn table 11. The undrawn yarn of the package on the creel truck is threaded from the creel into the drawing machine for the drawing operation.
  • the drawing machine When the creel is emptied of the undrawn yarn after the drawing operation for a given time, the drawing machine is discontinued and the empty creel is to be replaced. in order that the empty creel trucks may be pulled out, the winch 206 is actuated to wind the wire 204 and to pull the hook 205 connected to the wire 204. The top truck is now pushed back because of its registering with the hook 205, and the subsequent trucks backward of it are pushed back toward the entrance of the truck path. The operation of the winch 206 is conducted as with the use of a push button disposed near the truck path 2.
  • creel trucks An operator standing at the entrance pulls out the creel trucks one by one by pushing the button to the extent necessary to let the truck advance to the entrance and from the entrance all of them are conveyed manually or by appropriate other means and pulled out of the creel section in the drawing machine.
  • the empty trucks After changing their direction with the turn table 10, the empty trucks are arranged on the stand-by path 8.
  • the fresh creel trucks are, then, pushed into the emptied creel section by the same procedure as described above for creel formation. Afterwards empty creel trucks are loaded on the forklift truck and removed.
  • the effect of the present invention that is, the curtailment of time of replacing undrawn yarn packages and reduction of work load owe much to the installation of stand-by paths for creel trucks which paths intersect the drawing machines at the ends of the drawing machines besides the above-described method of pulling out the trucks.
  • the stand-by paths for filled and empty creel trucks are arranged side by side adjacent the truck paths over the drawing machines and consequently even if the op eration of lifting creel trucks to the stand-by platform takes much time, full package creel trucks can be made ready on the platform by the time of replacement of creels on the drawing machines.
  • the emptied creel trucks on the truck paths of the drawing machines are instantly pulled out to the emptied creel truck path on the stand-by platform and immediately after that, the full creel trucks are pushed into the creel sections of the drawing machines.
  • creel replacement can be conducted in a minimum time period. Immediately after that, the drawing machine is threaded to resume the drawing operation.
  • the operation rate of the drawing machines with apparatus of the present invention is highly elevated as compared with conventional apparatus.
  • the improvement comprising placing the creel trucks loaded with full packages on a stand-by platform adjacent the ends of the truck paths; at the time of replacing emptied packages by the full packages, withdrawing the creel trucks loaded with the emptied packages from a truck path to the stand-by platform and immediately feeding the creel trucks loaded with full packages from the standby platform to the truck path; lowering the empty creel trucks from the stand-by platform; and lifting full creel trucks to the stand-by platform for storage.
  • Apparatus for replacing yarn packages for use with drawing machines having drawing units on both sides thereof comprising a plurality of truck paths arranged above the drawing machines and extending therealong;
  • each of said truck paths has a groove for receiving said wire, a groove for moving said hook, and an inclined block for holding said hook disposed at the entrance of each truck path from said stand-by platform.
