Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil transfer device provided between processes such as in a steel mill, and more specifically, stores a coil transfer carriage and transfers it to a traverse carriage. Also possible for storage conveyors.

2. Description of the Related Art Conventional Problems and Problems Thereof In the above-described coil transfer device, the coil transfer carriage stored in the storage conveyor is sent to the next step transferred to the traverse carriage.

In order to carry out such transfer, it is sufficient to provide a transfer mechanism for retracting the coil transfer carriage to each of the transverse carriages, but this requires a transfer mechanism for all the transverse carriages, resulting in a high equipment cost. There's a problem.

Therefore, it is conceivable to provide such a transfer mechanism on the storage conveyor side. However, when transferring a heavy object such as a coil, it is common to pull the tip of the carriage. However, with such a towing system, when the coil transfer carriage is transferred to the traverse carriage, the transfer mechanism must be inserted into the transfer path of the traverse carriage. Therefore, until the operation of the transfer mechanism is completely completed, that is,
The transfer mechanism transfers the coil transfer carriage to the traverse carriage, and the traverse carriage must wait until it completely retracts from the trajectory of the traverse carriage, which not only prolongs the cycle time but also causes malfunction. There is also a risk of damage.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a storage conveyor configured so that the transfer mechanism does not interfere with the operation of the transverse carriage.

Means for Solving the Problems The present invention, when mounted on a traverse vehicle having a traveling rail and a transfer rail that can travel in a direction perpendicular to the traveling rail and is aligned with the traveling rail, For coil transfer that has an engaging recess that penetrates in the traveling direction of the traverse vehicle in the front part and the rear part that extend to the outer side in the width direction of the traverse car above the upper surface of the travel rail, and that is transferred on the travel rail. It has a trolley and a drive frame that is reciprocally driven below the traveling rail at the same time with a towing engagement pin that is engageable with and disengageable from the engagement recess of the front portion, and is transferred to the traverse trolley. The above problems are solved by a storage conveyor in which an engaging recess at the rear of the coil transfer carriage and a push-in engaging pin that can be engaged and disengaged are provided at the front end of the drive frame at the mounting end.

Action When the drive frame reciprocates at the same time when it is retracted and stopped, the pulling engagement pin of each drive frame is stopped at a predetermined relational position by the coil transfer carriage to which the pulling engagement pin should be engaged, and immediately before that. Coil transfer cart with coil mounted,
That is, if there is no actual carriage, if it is engaged in the engagement recess on the front end side of the coil transfer carriage, the coils placed on the coil transfer carriage one after another at the start end of the storage conveyor will move to the front of the storage conveyor. Packed storage.

The traverse carriage stops at the transfer end of the storage conveyor, and in order to transfer the real carriage from this to the storage conveyor, the front end of the drive frame on the transfer end side of the traverse carriage is provided separately from the towing engagement pin. The push-in engagement pin engages with the engagement recess on the rear side of the coil transfer carriage to drive the drive frame. When the coil transfer carriage is completely transferred to the traverse carriage, the coil transfer carriage extends beyond the front and rear portions of the traverse carriage in the width direction outside and stops. Immediately after transfer, the push-in engagement pin is engaged in the rear engagement recess, but since the engagement recess penetrates in the traveling direction of the transverse carriage, the push-in engagement pin is engaged. It is possible to activate the traversing cart even in the state where it is turned on. Therefore, the traveling of the transverse carriage is reciprocal drive of the drive frame, in particular, even when the drive frame comes closest to the transverse carriage, the traveling is not restricted and the transverse carriage is immediately moved when the transfer of the coil transfer carriage is completed. It is possible to drive to.

The engaging recesses 50a and 50b are respectively provided in the extending portions of the high-speed electric carriage 1 in the widthwise outer side when the carriage 7 is transferred to the high-speed electric carriage 1 in a sound manner. The parts are located before and after the coil transfer carriage. Further, it is provided above the upper surface of the traveling rail 8 so as not to interfere with the traveling rail 8 of the conveyor 3 for transporting the carriage even when the high speed electric truck travels.

Next, the operation of forward-storing the truck 7 on the traveling rail 8a by the connecting body 20 will be described. When the empty truck 7a is moved to the traveling rail 8a side by the traverser 9,
Moves backward by L and stops. The engaging pin 39a is the drive frame 1
The trailing end 7a is provided for pulling, and the engagement pins 39a and the like are individually rotated from the horizontal position to the vertical position above the upper surface of the traveling rail 8a. At this time, even if the stop position of the empty carriage 7a varies, the pulling engagement pin 39a is rotated at the stop position rearward of the front engaging recess 50a. The engaging recess 50a comes into contact with the lower edge of the rear engaging fitting 49b and stops. Next, when the connecting body 20 advances by a distance L larger than the pitch l, the pulling engagement pin 39a slides with respect to the lower edge so as to be engaged in the engagement recess 50a, and to the engagement fitting 49a. Hit empty car 7a to position b,

After that, the actual carriage 7 on which the coil C is placed advances by the distance l by engaging and disengaging the towing engagement pin 39, but the impact force at the start of the carriage is alleviated by the compression of the hydraulic shock absorber 33, and the hydraulic shock is absorbed during forward movement. A spring in the device 33 pushes the intermediate frame 29 back into its normal position. When the connecting body 20 decelerates near the forward limit, the carriage 7 coasts, and the engagement fitting 49b pushes the pulling engagement pin 39 to bring the intermediate frame 29 into contact with the cushion 36 and stop. Thus, the carriage 7 is made to step forward by l.

During the stepping operation, the solenoid valve 43 is operated so as to make the towing engagement pin 39 upright on condition that the carriage 7 is stopped at the backward limit position of the drive frame 17 and there is no preceding stop carriage 7 for rear-end collision. By activating the rotary actuator 41 in this way, the actual carriage 7 can be front-justified stored on the traveling rail 8a with a pitch l.

FIG. 16 is an elevation view of the traverse carriage, that is, the high-speed electric carriage 1, in which the traverse conveyor 2 is mounted by the wheels 89 attached to the frame 88.
It has a transfer rail 12a and a drive roller conveyor 12b which run on the rail 10 by a built-in motor and can be connected to the travel rail 8a and the top roller chain 59, respectively, on the frame. In the connected state, the real carriage 7 is transferred to the storage conveyor 5 and the empty carriage 7a is transferred to the conveyor 6, but in order to stop the positioning of the carriage 1 due to the transfer, it is placed in the frame 88. An arm 91 fixed to a fixed shaft of a pair of meshed gears 90 is provided, and this is driven by a motor so that the carriage 1 is fixed by gripping a positioning protrusion 92 fixed on the floor. Further, the upper end of the link 95 pivotally supported on the frame 88 is fitted into the recess 94 (Fig. 4) between the two locking metal fittings 93 protruding on the lower surface of the carriage 7 for locking the empty carriage 7a in place. The lower end of the link 95 and the arm 96 fixed to the shaft of the gear 90 are connected by the link 97 so that the fixing of the carriage 1 and the fixed stop of the empty carriage 7a can be performed at the same time.

The actual carriage 7 is transferred by the drive frame 17d (FIG. 2) provided at the transfer end of the storage conveyor 5. As shown in FIG. 2, this is performed by a drive frame 17d (FIG. 2) provided at the transfer end of the storage conveyor 5 on the end side of the horizontal transfer conveyor. As shown in FIG. 2, the push-in engagement pin 3 that engages in the rearward engagement recess 50b of the front carriage 7d (FIG. 3) on the storage conveyor 5 on the end side of the transverse conveyor.
9d and a pulling engagement pin 39e that engages with the engagement recess 50a in the front part of the truck 7e one behind are provided side by side, and the carriage 7e is advanced by the forward movement of the connecting body 20 to pull the carriage 7d by the pulling engagement pin 39e. The dolly 7d is pushed forward on the dolly 1 by the push-in engagement pin 39d and transferred while being moved forward to the position. The push-in engagement pin 39d is provided at the front end of the drive frame 17d so as not to interfere with the carriage 1 even when the drive frame 17d moves forward.

The transferred real truck 7d has the drive frame 1 at the engaging recess 50b extending from the high-speed electric truck 1 to the storage conveyor 5.
7d is in engagement with the push-in engagement pin 39d, but the engagement recess 5
0b penetrates in the traveling direction of the high-speed electric carriage 1, and the drive frame 17d and the push-in engagement pin 39d are located outside the locus of the high-speed electric carriage 1. Therefore, the operation of the drive frame 17d, that is, the engagement recess The high-speed electric carriage 1 can be started without waiting for the push-out engagement pin 39d to be detached from the drive mechanism 50b and the drive frame 17d to be retracted.

It can be easily understood that the trolley 7 can be removed from the trolley 1 by using the engaging pins 39d and 39e. Further, in this case, since the storage conveyor 5 and the empty carriage returning conveyor 6 respectively move in the opposite directions, the unloading of the coil C is performed at the transfer end of the storage conveyor.

Returning to FIG. 16, in order to hold the actual bogie 7 on the bogie 1 stably, a frame 88 is provided with a fork 99 having a bifurcated upper end, which is bent, and tilted by an electric linear actuator. By doing so, the upper portion of the wheel 14 is locked. Further, the guide rail 100 for the flange of the wheel 14 is fixed to the frame 88 in order to prevent lateral displacement of the empty carriage 7.

Electric power for the dolly 1 is supplied by sliding a current collector (not shown) provided on one side of the frame 88 and a power supply line provided along the rail 10. 101 is a control panel.

In the conveyor 3 for transporting the carriage connected to one side of the transverse conveyor 2 in the transport device having the above-described configuration, the empty carriage 7a laterally transported from the empty carriage returning conveyor 6 to the empty carriage 7a is transferred to the empty conveyor 7a at the start end of the storage conveyor 5. The coil C is loaded, and thereafter, the coil C is stepped forward, and is transferred onto the transfer rail 12a of the high-speed electric carriage 1 at the transfer end. On the other hand, on the conveyor 12b of the high-speed electric carriage 1, from the empty carriage returning conveyor 6 connected to the opposite side of the horizontal conveyor 2 to the empty carriage 7a.
, The high-speed electric trolley 1 carries the real trolley 7 and the vacant trolley 7a, or one of them is placed to move at a high speed to another position,
Therefore, the carriage is transferred to another storage conveyor 5 or the empty carriage returning conveyor 6. Therefore, the coil C always moves together with the dolly 7, and the coil C
Information of the coil C is moved together with the dolly 7, it is not necessary to transfer the information of the coil C to the CPU or the like controlling the conveyor each time the dolly 7 is transferred to another conveyor. Information processing becomes possible.

Further, when the processing efficiency such as the processing of the coil C on the carriage transfer path becomes unbalanced, the buffer function of the storage conveyor 5 can smooth the whole flow, and at the same time, the empty carriage at the loading point can be used. The excess and deficiency can be resolved by the horizontal carriage of the empty carriage by the high speed electric carriage.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, even when the drive frame has just transferred the coil transfer carriage to the transverse carriage, the starting and traveling of the transverse carriage may be restricted by these operations. In addition, there is an effect that rapid conveyance can be performed and the cycle time can be shortened. Thus, the degree of freedom in operating the drive frame and the traverse carriage is increased, and the processing efficiency of the coil transfer carriage is significantly improved.
