Description

Pallet circulator with centering function {EQUIPMENT OF CIRCURATING FOR PALLET WITH FUNCTION OF CENTERING}

The present invention relates to a pallet for seating and transporting a coil-type product in order to seat a coil produced in a continuous annealing and to transfer it to a packaging process, or to remount a coil produced for drawing a coil.

In particular, the reprocessing workload is increased due to the delay of pallet circulation, the production speed is reduced due to the work speed and process interruption, and the centering of coiled products seated on the pallet is corrected. The present invention relates to a movable coil-type centering device that can be supplied smoothly without problems in time.

As shown in FIG. 1 of the accompanying drawings as a conventional apparatus, the pallet 108 is a movable structure, which seats the coiled product 107 and transfers it to a packaging line in a production process, and the coiled product 107 for packaging. The drawn ball pallet 108 is a circulation device which is conveyed in a continuous process by using a pallet feedcar 111 of the bullfighting pin 110 for high speed trolley in order to allow the coiled product 107 to be separately produced. When the product 107 loaded on the furnace pallet 108 is transferred to the packaging process due to the poor centering of the product 107, the transfer 101 draws the coil-shaped product 107 to securely transfer the centering to the skid of the packaging process. It is installed so that

The centering correction operation of the transfer 101 induces the center of the coil in the state where the coiled product 107 is pulled out from the pallet 108, and does not fix the outer peripheral strip of the coiled product 107 with tape. Therefore, the problem of unwinding the outer circumferential strip in the process of drawing out the coil type product to calibrate the center,

In the taping machine for tape fixing the outer portion of the coiled product, if the center of the coiled product coincides with the coiled product 107 seated on the pallet 108, the taping operation is performed before the operation of the transfer 101 and the pallet In the case where the center of the coiled product 107 seated is defective, the material having a thickness of 0.8 mm or more is unscrewed in the process of calibrating the center because the adsorption force of the tape is reduced by the outer diameter strip weight when the tape is attached.

Since the worker enters the facility and fixes the outer strip of the coil type product 107 with a plurality of tapes, the centering of the transfer 101 needs to be corrected. If the width is wide (1500mm or more), the collision with the taping machine or transfer 101, which is the entrance equipment of the packaging process, or the installation of the conveyor skid during the conveying of the conveyor due to the failure of the center may occur. Occurred,

Depending on the operator, the coiled product 107 is drawn out on the pallet 108 using the traverse cylinder 102, the traverse rail 105 and the bullfighting pin 110 of the high speed bogie and is generated during the center calibration process. Information on the coil type product 107 because it is necessary to turn off the power of all the related equipment such as the bullfighting pin 110 and the traverse with the feed car 104 of the high-speed bogie in order to prevent the collision with the coil in advance. Of the coil type product 107 continuously produced in the continuous annealing process is not divided and delivered to the packaging process because the operator has to retrace and adjust the information to check the information on the product 107 in the field. After re-splitting, reworking will cause problems such as reduced production and cost.

Reference numeral 103 not described here is a bullfighting pin, 106 is a pallet clamp, and 109 is a non-improving (conventional) rail.

The present invention is to solve the problems described above, when the coil pallet detects the width of both ends of the product when passing through the high-speed trolley, if the centering is poor, rotates to recognize the movement amount by the chain plate and the computing device capable of left and right shifting Correct the centering of the coiled product before taping

In addition, by using the pallet circulator that replaces the function of the previous traverse with feeder that rotates the pallet forward and backward with the rotation type centering function, the continuous pallet annealing the empty pallet using the high-speed bogie It can be directly circulated to the exit conveyor to shorten the circulation time of the pallet to provide a smooth operation and productivity by improving the output of the continuous process, reduction of fines, cost and defect rate.

Referring to the operation of the present invention configured as described above are as follows.

When the pallet circulator with the centering function of FIG. 2 and the coil pallet 703 enter the pallet circulator with the centering function as shown in FIGS.

The coil pallet clamp cylinder part 300 receives a start instruction, and the clamp stopper 301 of the traverse cylinder 303 moves forward and stops ('B' in FIG. 7) upon detection of the built-in front photosensor 302. When the upper and lower cylinders 309 operate and descend, when the photosensor 307 sends a stop signal and completes the lowering, the stopper 301 and the guide bar 708-1 of the guide guide 708 are inclined. Movement is stopped ('da' in Fig. 7) and the forward and backward distances of the transfer are determined. Since the adjustment of the left and right distance of the transfer is adjusted according to the movement of the steel conveyor unit 700, when the center ring is fixed, the transfer 101 is instructed to transfer the coil to the packaging process ('B' and '7' in FIG. 7). When the up-down cylinder 309 rises and stops according to the detection of the phase photosensor 306, the stopper 301 is released and returns to its original state. And the ball pallet 703 that has been moved laterally by the conveyor unit 700, as described with reference to 'a' and 'b' of FIG. And 'la' is circulating action is always the left and right distance adjustment of the transfer in detail, when the pallet 703 is moved 1 pitch in response to the left and right moving start instruction, the operation unit 508 operates the built-in drive motor 501 When instructed, the steel chain conveyor 700 connected to the shaft 504 and the chain plate 702 is connected to the belt pulley 507 and the shaft 504 to move to reach the indicated distance ('6' in FIG. 6). ), The pallet circulator with the centering function is detected by the photosensor 510 and stops.
