Description

Technical Field

[0001] The invention relates to the technical field of waste cleaning equipment, and in particular to a full-automatic ejector waste cleaning equipment and an ejector installation method. Background Art

[0002] The cleaning of waste edges of printed products in the printing and packaging industries is called waste stripping, which is a necessary procedure for the trimming and forming processes of printed products. The emergence of waste stripping machines has replaced manual hammer waste stripping, which not only reduces labor intensity but also improves work efficiency.

[0003] In the current waste stripping machines for printed products, most of them require workers to manually place the printed products into the waste stripping machines, separate the printed products from the waste edges through ejectors, and after separation, workers need to manually take out the separated printed products and put them back into the printed products to be stripped. This method greatly reduces the work efficiency. In the existing printed products with a thickness of 0.2-0.3mm, in actual production, in order to save costs, generally only 2-3mm of waste edges are reserved after die-cutting of printed products. For the waste edges of this size, ejectors of corresponding sizes are required. However, since the outer diameter of the ejector is too thin, its strength is greatly reduced. If the number of printed products to be stripped is large, the waste edges of the ejector are not large enough to be stripped. If the amount is too large, the ejector pin will easily deform when lifting the printed product, and the ejector pin needs to exert greater force to eject all the waste edges when cleaning a large number of printed products, which will cause indentations on the upper and lower surfaces of the printed products and affect product quality. If the number of printed products to be cleaned is reduced, although the load on the ejector pin can be reduced, the frequency of paper feeding by the staff will be greatly increased, thereby reducing the cleaning efficiency and the labor intensity of the staff, and because the thickness of the printed product is very small, the edge of the printed product is deformed when the printed product is lifted by the ejector pin, resulting in the upper ejector pin being unable to press down the waste edge of the printed product, thereby affecting the cleaning of the printed product.

[0004] It can be seen that for printed products with a waste edge width of 2-3mm, fine needles of corresponding sizes are required for waste cleaning. However, the number of printed products stacked each time the fine needles are used is limited, which not only reduces production efficiency but also increases the labor intensity of the staff. Therefore, there is currently no technical solution for using ejector pins of this specification. Summary of the invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a fully automatic ejector waste cleaning device, which is suitable for the waste cleaning of ultra-thin printed products, realizes fully automatic paper feeding, waste cleaning and paper collection, speeds up the waste cleaning speed and improves production efficiency.

[0006] In order to achieve the above object, the present invention discloses a fully automatic ejector waste removal device, comprising:

[0007] A waste removal platform, wherein a waste removal conveyor belt is arranged on the waste removal platform, and a plurality of through holes are arranged in a matrix on the surface of the waste removal conveyor belt;

[0008] A paper feeding conveyor belt, which is arranged at the head end of the waste removal platform and is used to feed the printed products to be removed that are stacked on the first stacking device onto the waste removal conveyor belt;

[0009] An upper ejector mechanism, which is escalably disposed above the waste stripping platform and is used to press down the waste edges of the printed products on the waste stripping conveyor belt when the upper ejector mechanism descends;

[0010] A lower ejector mechanism, which is escalably disposed below the waste stripping platform and is used to lift up the printed product on the waste stripping conveyor belt when the lower ejector mechanism rises, so as to separate the printed product from the waste edge;

[0011] A paper inserting conveying mechanism is slidably arranged at the end of the waste stripping platform, and is driven by a paper collecting driving device to move toward the direction of the waste stripping conveyor belt, so that the head end of the paper inserting conveying mechanism extends into between the printed product and the waste edge to support the printed product, and the printed product is sent to the second stacking device through the paper inserting conveying mechanism, while the waste stripping conveyor belt continues to move forward to send the waste edge into the waste frame.

[0012] Furthermore, it also includes a stacking mechanism, which is arranged on the first stacking device. The stacking mechanism includes a pusher claw and a clamping claw. The pusher claw is slidably arranged between the first stacking device and the paper feeding conveyor belt. The clamping claw is a pair of claws arranged on both sides of the pusher claw. The pusher claw is driven by a telescopic driving device to press against the edge of the printed product, and the pusher claw is driven by a toggle driving device to swing and lift the edge of the top layer of the printed product from the side, so that the clamping claw clamps the printed product lifted by the pusher claw, thereby realizing automatic stacking of the stacked printed products.

[0013] Furthermore, the paper insertion and conveying mechanism includes a paper receiving tray and a unloading conveyor belt. The paper receiving tray is slidably arranged on the unloading paper support frame, and the unloading conveyor belt is tensioned on the paper receiving tray. A plurality of paper supporting arms are arranged at intervals along the width direction at the front end of the paper receiving tray, so that the paper receiving tray can avoid the upper ejector pin and the lower ejector pin and enter the waste clearing platform to support the printed products with the waste edges removed, and then the printed products with the waste edges removed are sent out by using the unloading conveyor belt, thereby realizing automatic paper collection.

[0014] Furthermore, a slot is provided at the front end of the paper support arm, a guide wheel is inserted in the slot, a transmission shaft is rotatably provided at the rear end of the paper support arm, and the unloading conveyor belt is tensioned between the guide wheel and the transmission shaft, so that after the paper receiving tray supports the printed products with the waste edges removed, a plurality of unloading conveyor belts are used to send the printed products out of the waste removal conveyor belt.

[0015] Furthermore, the upper ejector mechanism includes an upper ejector baffle and an upper ejector positioning plate. The upper ejector baffle can be raised and lowered above the waste cleaning platform. The upper ejector positioning plate is slidably arranged on the bottom surface of the upper ejector baffle. A plurality of upper ejectors are inserted on the upper ejector positioning plate according to the shape of the waste edge of the printed product, so that when the upper ejector baffle is lowered, the plurality of upper ejectors respectively press the waste edge of the printed product on the waste cleaning conveyor belt.

[0016] Furthermore, the lower ejector mechanism includes a lower ejector plate, which is levitationally arranged below the waste cleaning platform, and a lower ejector positioning plate is mounted above the lower ejector plate. A plurality of lower ejectors are inserted on the lower ejector positioning plate according to the shape of the printed product, so that when the lower ejector plate rises, the plurality of lower ejectors pass through the through holes of the waste cleaning conveyor belt to lift the printed product.

[0017] Furthermore, the paper insertion conveying mechanism also includes a paper unloading support rack, a paper unloading rotating rack is rotatably arranged on the paper unloading supporting rack, a paper receiving slide is slidably arranged on the paper unloading rotating rack, and the paper receiving support plate is fixedly arranged on the paper receiving slide, and the paper unloading rotating rack is driven by a flipping driving device to drive the paper receiving slide to flip up and down. When installing the ejector, the paper unloading rotating rack can be driven by the flipping driving device to flip upward, thereby forming a pedestrian passage between the paper insertion conveying mechanism and the waste cleaning machine for the staff to install the ejector.

[0018] Furthermore, the waste cleaning conveyor belt includes a belt, a driving roller, and a driven roller. The driven rollers are a pair and are rotatably arranged at the two ends of the top surface of the waste cleaning platform respectively. The driving rollers are a pair and are rotatably arranged at the head and tail ends of the waste cleaning platform. The belt is laid on the top surface of the waste cleaning platform, and the two ends of the belt are fixedly connected around the driven roller and the peripheral wall of the driving roller respectively. The driving roller is driven by a rotating driving device to link the belt to reciprocate, so that the reciprocating motion of the belt is used to clean the waste between the upper ejector mechanism and the lower ejector mechanism of the printed product paper feeding, and the separated waste edges are sent into the waste through the waste cleaning conveyor belt, thereby realizing the automatic transportation of the printed product and the automatic cleaning of the waste edges, reducing the labor intensity of the staff.

[0019] Furthermore, a waste cleaning upper mold mounting frame is slidably arranged above the waste cleaning conveyor belt, and connecting slide rails that slide with the upper ejector positioning plate are fixedly arranged on both sides of the rear end of the waste cleaning upper mold mounting frame, and a positioning monitoring module is arranged at the end of the connecting slide rail.

[0020] The present invention also provides a method for installing an ejector pin, comprising the following steps:

[0021] Step 1: The upper ejector positioning plate is lowered to align with the end of the connecting slide rail, and the staff pushes the upper ejector positioning plate from the upper ejector baffle plate onto the connecting slide rail;

[0022] Step 2: The staff places the printed product on the upper ejector positioning plate, and then inserts the positioning pin through the printed product and inserts it into the upper ejector positioning plate to fix the printed product on the upper ejector positioning plate;

[0023] Step 3: The staff tears off the waste edge of the printed product and inserts several upper ejectors on the upper ejector positioning plate along the outline of the printed product;

[0024] Step 4: Finally, push the upper ejector positioning plate under the upper ejector baffle.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention uses a pin with a finer radius, which can adapt to printed products with smaller waste edges. The force required for ejection is smaller, and it is not easy to cause indentations on the surface of the printed products, which effectively improves product quality. (2) The fine pin in the present invention is combined with the design of the stacking mechanism and the paper conveyor belt, which can realize the fully automatic stacking and conveying of printed products in small quantities and batches, so that the stacking thickness of the printed products to be cleared each time is small, making it easier to clear waste with the pin, reducing the load on the pin, and eliminating the need for manual handling by workers, greatly improving the waste clearance efficiency, reducing labor intensity, and making the use of fine pins for waste clearance practical. (3) The stacking mechanism in the present invention uses a pusher and a clamp to stack, which can avoid the printed product being unable to be normally lifted due to the waste edge of the printed product being too small. Therefore, when the pusher lifts the printed product, the clamp is used to clamp the edge of the printed product, so that multiple printed products can be smoothly lifted, greatly improving the stacking efficiency and stability of the printed product. (4) The present invention adds a number of paper support arms arranged at intervals on the paper receiving tray, so that when the paper receiving tray extends into the waste removal platform, it can avoid the upper ejector pins and the lower ejector pins, and avoid collision with the upper ejector pins and the lower ejector pins. (5) The ejector pin installation method of the present invention greatly reduces the number of upper ejector pins due to the small number of printed products to be removed, and the ejector pins can be removed by magnets, thereby greatly improving the efficiency of needle replacement and quickly adapting to different printed products.

[0045] Specifically, in this embodiment, the thickness of each printed product is 0.1-0.3mm, and the width of the waste edge of the printed product is about 2-3mm, which can greatly save production costs. However, in this embodiment, the thickness of the printed product and the width of the waste edge are very thin, so the number of printed products to be picked up each time is preferably about 25, so that the claw 81 can better pick up the printed product, and at the same time, the force on the lower ejector pin can be greatly reduced. In addition, in this embodiment, the outer diameters of the upper and lower ejectors are 2-3mm, which can adapt to printed products with smaller waste edges. Therefore, the force required for the lower ejector pin to rise and lift the printed product is smaller, thereby achieving rapid separation of the printed product and the waste edge, and it is not easy to cause indentations on the surface of the printed product, effectively improving product quality, and speeding up the waste removal speed.

Side baffles are also arranged on both sides of the waste cleaning conveyor belt 11. A side plate driving device is fixedly installed on the waste cleaning platform 1. The side plate driving device preferably adopts an electric cylinder to drive the side baffles to limit the two sides of the printed product through the side plate driving device, so as to realize the positioning of the printed product. The paper stop driving device and the side plate driving device can adjust the telescopic distance of the paper stop and the side baffle according to the width of the printed product, so as to position the printed products of different sizes, so as to ensure that the upper ejector pin can accurately press the waste edge of the printed product.

[0047] The specific work is that after the paper feeding conveyor belt 2 feeds the printed product into the waste cleaning conveyor belt 11, the paper stop lifting drive device drives the paper stopper to descend, and at the same time, the paper stop drive device drives the paper stopper to extend, so that when the waste cleaning conveyor belt conveys the printed product to between the upper ejector mechanism 3 and the lower ejector mechanism 4, the paper stopper is used to limit the rear end of the printed product, and at the same time, the side plate drive device drives the side plate to extend to limit the two sides of the printed product to ensure the accurate position of the printed product, and then the downward pressure drive device 132 drives the upper ejector to descend and press the waste edge of the printed product, and at the same time, the downward pressure drive device drives the lower ejector to rise to lift the printed product, and then the paper stopper and the side plate are reset, thereby realizing the automatic separation of the printed product and the waste edge.

[0050] In this embodiment, the distance between the paper supporting arms 511 is slightly larger than the outer diameters of the upper and lower ejector pins, so that when the paper receiving tray 51 enters the waste clearing conveyor belt 11, the paper receiving tray 51 can avoid the upper and lower ejector pins to prevent the paper receiving tray 51 from colliding with them and affecting the paper receiving work.

[0051] In addition, in this embodiment, a waste frame is placed below the waste stripping platform 1 and the paper insertion conveying mechanism 5 to receive the waste edges sent out by the waste stripping conveyor belt 11, and the height of the paper receiving tray 51 in this embodiment is slightly higher than the waste stripping platform 1, so that a gap is formed between the end of the waste stripping conveyor belt 11 and the paper receiving tray 51 for the waste edges to pass through.

[0052] Reference Figure 4-Figure 7 As shown, during specific operation, when the lower ejector pushes up the printed product and separates it from the waste edge, a gap is formed between the printed product and the waste edge, and the paper receiving drive device drives the paper receiving slide 55 to move toward the direction of the waste removal conveyor belt 11, so that the plurality of paper supporting arms 511 on the paper receiving support plate 51 extend into the gap between the printed product and the waste edge, and at the same time, the gap between the plurality of paper supporting arms 511 avoids the upper ejector and the lower ejector, and then the upper ejector and the lower ejector are reset, so that the plurality of paper supporting arms 511 support the printed product, and The waste edges are retained on the waste clearing conveyor belt 11, and then the paper receiving drive device drives the paper receiving slide 55 to move toward the second stacking device 7. At the same time, the rotary drive device drives the waste clearing conveyor belt 11 to move forward toward the end, and the waste edges are sent into the waste frame under the conveyance of the waste clearing conveyor belt 11. The unloading drive device links the unloading conveyor belt 52 to rotate and send the printed products with the waste edges removed to the lower paper conveyor belt 56, so that the lower paper conveyor belt 56 sends the printed products to the second stacking device 7 for stacking.

[0053] Reference Figure 6As shown, further, a flipping drive device 541 is hinged on the head end of the unloading paper support rack 53. In this embodiment, the flipping drive device 541 preferably adopts a cylinder, and its telescopic end is hinged to the unloading rotating rack 54. Each time a different printed product is replaced, the upper ejector of the upper ejector mechanism and the lower ejector of the lower ejector mechanism need to be rearranged. Therefore, the unloading rotating rack 54 is driven to flip upward by the flipping drive device 541, so that a pedestrian passage is formed between the waste cleaning platform 1 and the unloading paper support rack 53, providing space for the staff to adjust the upper ejector and the lower ejector.

[0054] Connecting slide rails that slide with the upper ejector positioning plate 32 are fixedly arranged on both sides of the rear end of the waste cleaning upper mold mounting frame 13, and a positioning monitoring module is arranged at the end of the connecting slide rail. In this embodiment, the positioning monitoring module preferably adopts an infrared sensor to detect the position of the upper ejector positioning plate 32.

[0055] Reference Figure 1-Figure 7 Specifically, the present invention further provides a method for installing an ejector pin, comprising the following steps:

[0056] Step 1: The upper ejector positioning plate is lowered to align with the end of the connecting slide rail, and the staff pushes the upper ejector positioning plate from the upper ejector baffle plate onto the connecting slide rail;

[0057] Step 2: The staff places the printed product on the upper ejector positioning plate, and then inserts the positioning pin through the printed product and inserts it into the upper ejector positioning plate to fix the printed product on the upper ejector positioning plate;

[0058] Step 3: The staff tears off the waste edge of the printed product and inserts several upper ejectors on the upper ejector positioning plate along the outline of the printed product;

[0059] Step 4: Finally, push the upper ejector positioning plate under the upper ejector baffle.

[0060] The specific ejector installation method is as follows:

[0061] When the upper ejector pin needs to be adjusted, the upper mold mounting frame 13 is driven to move to the head end of the waste removal platform 1 through the sliding drive device, and the downward driving device 132 drives the upper ejector baffle 31 to descend until the positioning monitoring module detects the upper ejector positioning plate 32, and then the downward driving device 132 stops. The staff pulls the upper ejector positioning plate 32 out of the upper ejector baffle 31 and pushes the two sides of the upper ejector positioning plate 32 onto the connecting slide rails. Then the staff places the single printed product to be removed on the upper ejector positioning plate 32. By passing the positioning pin through the printed product and inserting it on the upper ejector positioning plate 32, the printed product is fixed to avoid deviation that affects the installation accuracy of the upper ejector. Then the staff will tear off the waste edge of the printed product, and then insert a number of upper ejectors on the upper ejector positioning plate 32 along the contour of the printed product, so that the upper ejectors can accurately and evenly press the waste edge of the printed product when pressed down. After the upper ejectors are installed, the staff will push the upper ejector positioning plate 32 into the upper ejector baffle 31 to achieve the installation of the upper ejectors.

[0062] When it is necessary to replace other printed products, the staff will hold a magnet and place it on the top of the upper ejector pins so that the magnets attract several upper ejector pins, so as to quickly pull the several upper ejector pins out of the upper ejector pin positioning plate 32. After all the upper ejector pins are taken out, the staff will take out the positioning pins on the printed product and replace it with printed products of other products. The above-mentioned needle installation operation is repeated to complete the replacement of the printed product.

[0063] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any modifications made according to the spirit of the main technical solution of the present invention should be included in the protection scope of the present invention.
