ベヤに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention, when used for transferring coils in a steel mill, for example, stores the coils placed on a conveyor in front of the conveyor.
This invention relates to a buffer storage conveyor that is effective for absorbing imbalances in processing capacity between upstream and downstream equipment and improving operational flexibility.

止精度が低いという問題もある。Conventional technology Conventionally, conveyors for transferring coils in steel plants were:
There are two methods: placing the coil directly on the conveyor chain, and placing the coil on a trolley and pulling it with a chain directly connected to the trolley. However, in either method, the coil moves along with the chain, so if the coil is at the end of the conveyor, it will become inoperable, leading to the shutdown of upstream equipment. Furthermore, since the number of coils loaded on the conveyor is large, there is a drawback that a large amount of driving force is required. Furthermore, the chain drive system generally has a problem in that the accuracy of stopping the truck is low due to elongation of the chain and back and forth play in the engagement and disengagement device provided between the chain and the truck.

する。Means for Solving the Problems The present invention provides drive frames below the transfer path of the transfer cart at fixed pitches of the transfer path so that they can reciprocate all at once in the transfer direction by the pitch. The drive frame is provided with an engagement pin that engages and disengages by going up and down into the engagement hole provided in the transfer cart, and each transfer cart or each drive frame is provided with a locking device that holds the engagement pin in an engaged state. The gist of the present invention is a structure of a buffer storage conveyor that is provided with an engagement pin push-up device that performs a selective operation at a frame stop position, and a lock release device that releases the holding at the stop position.

動フレームは一斉に一定ピッチだけ後退する。Operation: Each transport carriage moves forward by a fixed pitch together with the drive frame by insertion of the engagement pin from the drive frame, and during this period the engagement pin is held in engagement with the carriage by the locking device. While the carriage is stopped at the forward end, the engagement pin is released from the carriage by the lock release device. Next, the drive frame moves back by a certain pitch all at once, leaving this truck behind.

The lever 59 is rotated 90 degrees to move the stop arm 60 from the release position shown by the chain line to the solid line position where it blocks the path of the empty truck 3a. At this time, the chevron-shaped guide plate 63 fixed to the stop arm 60 comes out into the passage of the protruding part of the pin 56, and the approaching empty truck 3
The pin 56 of a is made to ride on the chevron-shaped top plate 64, the button 54 is tilted to the position indicated by the chain line in FIG. 5, and the engagement between the hook 53 and the pin 55 is released. Thereafter, the front protrusion 65 of the empty truck 3a hits a stopper 66 provided on the stop arm 60 and stops. When stopped, the front roller 8a of the empty truck 3a enters the recess 67 of the rail 1b, and the empty truck 3a stops stably.

７０と係合したのち下降される。When the engaging collar 70 is not engaged with the claw 74, (1) If the arriving engaging pin 20a does not need to move up and down,
The pawl 74 should be at the lower end and at the rotational position a (, 2) If the engaging pin 20a is in the raised position, it must be lowered, so after the engaging pin 20a arrives, the pawl 74 will move to the cylinder 78b. At the rising end, the cylinder 78a rotates the cylinder 78a to the rotation position a, engages the engagement collar 70, and then lowers the cylinder 78a.

た効果がある。Effects of the Invention Since the present invention is configured as described above, the cart can move forward until it approaches the preceding cart, and even if the loading processing of the preceding cart is delayed, it can be stored on the conveyor, and the conveyor It has the effect of absorbing the imbalance in the processing capacity of upstream and downstream equipment, giving high flexibility to operations, and when a large heavy object such as a coil is loaded on a trolley, the stored trolley can be easily transported. Since no power is required, the transfer power is small, resulting in a large energy-saving effect.Furthermore, since ranks are used for transfer, stopping accuracy is excellent, and other excellent effects are achieved.
