Description

Automatic transfer system of paper tube

Technical Field

The invention belongs to the field of automation, and particularly relates to a roll-shaped product transferring system.

Background

When various middle-high grade thin (including ultra-thin) plastic films, metal foils, paper, EVA adhesive films and other materials are rolled up at high and low speed and then transported and stored, the prior art is to put the products into a paper box and then seal the box and then transfer the box by a manual hydraulic forklift or a fuel gas locomotive. In addition, the directional fixed-point transfer is performed by adopting a conveying line mode. In the transferring process, when the winding of the paper tube body of the winding head is completed, the winding head automatically unloads the paper tubes from the unloading system, and operators manually sleeve the paper tubes into the winding shaft one by one after the unloading is completed.

Stacking occurs due to the products being loaded into the cartons. When the product is transversely installed, the contact surfaces of the products (cylindrical) are in a line, so that the products are easy to squeeze and deform under the influence of gravity, and the surfaces are scratched and worn; when the vertical packing is carried out, the end faces of the products are stacked, and the end faces are easy to rub and abrade when moving under the action of gravity. And the container is placed in the box, so that the container is easy to be placed in disorder without attention, and the container is inconvenient to assemble and disassemble (store).

When the paper box is used for packaging, the repeated use times of the paper box are limited, and the cost is increased. The gas and fuel locomotives are adopted for transferring, and the production cost is increased by using locomotive loss and fuel utilization. The directional fixed-point transfer is carried out by adopting a conveying line mode, a certain plane space from an input point to an output point is occupied, certain requirements are met on the whole layout, and meanwhile, the cost occupied by equipment manufacturing cost is improved by a certain amount.

The paper tubes are sleeved into the winding shafts one by one manually by operators, which is time-consuming, labor-consuming and low in efficiency. At the same time, a large number of people are required, and a certain pressure is also exerted on the personnel department.

Detailed Description

The technical scheme of the invention is further described below with reference to the accompanying drawings:

The product quality detection equipment detects that the qualified product is conveyed to the tail end through the product detection conveying line, after the paper tube is detected by the tail end photoelectricity, a signal is sent to the PLC of the control center, the PLC instructs the tail end ejection cylinder to collect the product ejected from the paper tube and then return the product immediately, and the next ejection instruction is waited.

The product enters the product collecting and conveying line, is collected from two sides to the center, counts only when the product enters 1, and when the quantity of the product reaches a preset value (the maximum quantity of paper tubes inserted by a single rod of a transfer mechanism), a control center PLC sends out an instruction, controls a pushing cylinder in the middle of the collecting and conveying line to act, pushes the preset quantity of the product into a 4-product automatic sectional roller line, returns after the product is pushed in, and waits for a next pushing instruction.

After each predetermined amount of products are pushed in by the pushing cylinder in the middle of the collecting conveying line, the control center PLC instructs the segmented roller line to move forward for a certain length (the guide distance between the guide rods of the transfer mechanism), and when the stepping operation times reach a predetermined value (the number of the guide rods of the transfer mechanism), the control center PLC sends a loading instruction or an alarm to the automatic loading mechanism according to the condition of the subsequent working procedure (whether the loading mechanism meets the loading condition or not) to inform personnel to process.

After the loading mechanism receives a loading instruction sent by the control center PLC, the servo driver drives the servo motor to insert the loading guide rod into the inner diameter of the paper tube on the segmented roller line, and the paper tube is not easy to fall off due to the existence of a physical expansion opening at the tail end of the guide rod. After the guide rod is connected into the paper tube in series, the PLC controls the servo driver to enable the servo motor to enable the guide rod to ascend for a certain distance, and after the ascending is completed, the PLC commands the three servo drivers to control the guide rod in the X/Y/Z direction, so that the guide rod can place the paper tube on a bracket (stainless steel tube) in the transfer vehicle. After the guide rod is put out, the guide rod exits the transfer car to wait for the next loading action instruction.

The packing mechanism completes the paper tube loading operation from the paper tube to the transfer vehicle line by line in a mode of bottom part first and upper part second.

When the number of product loading lines in the transfer vehicle reaches a set value (the transfer vehicle is full of products), the control center PLC sends a transfer vehicle product output signal.

The transfer vehicle fully loaded with the product is operated to the position of the automatic opening and closing device manually or by the VGA trolley (under the condition that the transfer vehicle is borne by the VGA trolley), the automatic opening and closing device senses that the transfer vehicle is arranged, the servo motor is driven by the servo driver to slowly rotate on the upper rotating arm, the rotating arm drives the roller on the upper part of the door of the transfer vehicle, and the door of the transfer vehicle is closed.

The transfer car is operated to the position of an automatic opening and closing mechanism (a car unloading side) of the paper tube transfer car by a manual or VGA trolley in a closed state, the transfer car is sensed by the automatic opening and closing mechanism of the transfer car, the servo motor is driven by the servo driver to slowly rotate through a PLC instruction of the control center, and the upper idler wheel of the car door of the transfer car is driven by the spiral arm to open the car door of the transfer car.

After the door of the transfer vehicle is opened, the transfer vehicle is operated to the lower position of the product moving-out transfer vehicle mechanism by a manual or VGA trolley, and the control center performs accurate positioning or manually delivers the product to a preset position according to a preset signal (color signal) during charging.

After the transfer car reaches the accurate position of unloading the pipe, the product moves out of the guide rod of the transfer car mechanism, and the guide rod is driven by a servo motor at the side of the pipe unloading side (X/Y/Z directions) instructed by a PLC (programmable logic controller) control center, the center line of the guide rod is aligned with the center line of the paper pipe at the highest layer of the transfer car, and the guide rod is ensured to correspond to each row of the paper pipes in the transfer car.

The moving-out mechanism guide rod is controlled by a control center PLC to be inserted into a paper tube (the tail end of the guide rod is provided with a locking mechanism, the paper tube is not easy to fall off), and after the guide rod reaches the paper tube at the rearmost end (the paper tube is inserted by the guide rod), the control center PLC instructs a servo driver to control a servo motor to lift the guide rod, so that a product is transited to the moving-out mechanism guide rod.

After the guide rod of the moving-out mechanism is fully loaded with products, the control center PLC controls the guide rod to be aligned with the center line of the guide rod of the product moving-out transfer mechanism one by one, and then the PLC controls the push rod servo driver to control the servo motor to operate, and the paper tube on the moving-out guide rod is sleeved into the transfer guide rod.

After a guide rod of the product sleeved into the transfer mechanism is arranged in a paper tube, the transfer side servo driver is instructed by the control center PLC to control the servo motor to rotate the transfer guide rod by 180 degrees. And after the rotation of 180 degrees is finished, a transfer finishing signal is sent to the control center PLC.

After receiving the transfer completion signal, the control center PLC transmits the signal to a sleeve mechanism of the subsequent equipment, and judges whether to wait or immediately move the paper tube to the sleeve mechanism of the terminal using equipment according to the return information of the subsequent equipment.

When the product on the transfer guide rod is pushed to the sleeve mechanism by the servo motor controlled by the servo driver controlled by the PLC command pushing of the control center, the transfer guide rod rotates back to the original position to wait for the next action command.

The sleeve mechanism transfers the paper tube to the desired end use device as required.

The above actions are cycled.

The invention can also be used in the winding industries of paper making, films and the like, and is also suitable for the chemical fiber spinning production and use industries of stainless steel, color steel plates, aluminum foils, copper strips, electronic glass fiber cloth, non-woven fabrics, spandex filaments and the like.

The following is calculated by taking a small paper tube as an example:

Assuming that a small paper tube factory has 5 paper tube rolling machines TSJG-600 machine heads and 2 paper tube rolling machines for producing excircles Paper tubes with the wall thickness of 15mm are matched with a paper tube rolling machine with the speed of 18m/min, a two-shift work, a daily work for 16 hours and a yearly work for 360 days, and an oven, cutting-off, detection and the like, and the specification of the product is 100mm. The throughput of the whole plant is: 18x60x16x360x 5/0.1= 311040000, the yield is 95%, and the actual throughput is 311040000x0.95= 295488000, see table 1.
