Stop plate stacking system

Abstract

This relates to the field of packaging products into smaller, grouped packages. [Solution] (1) A method to reduce line pressure to 0 when the product transport level of the belt conveyor is raised by 10 mm, with a stop plate receiving line pressure when raised. (2) To shorten the distance the products travel, a method of stacking them in the vertical direction is used to shorten the distance and reduce the speed. (3) For stacking box products, a method of stacking them on a receiving plate in 1st, 2nd, and 3rd layers is used, and even if the number of layers increases, the discharge operation is performed only once. (4) The discharge device is a box motion type, where the speed increases during discharge movement, but pushes out at 0 speed at the discharge point. With methods (1) to (4), the speed can be extended from about 20 times / minute, and the frequency can be increased, but the frequency can be further reduced by using a box motion with 0 line pressure and pushing out at 0 discharge speed.

[0004] (1) How to control the line pressure of a belt conveyor that transports products. As the line processing speed increases, control becomes more difficult. (2) Means to solve the problem by reducing the frequency of jamming by setting the product movement speed to 45 m / min or less (45 m / min is based on experience) or by minimizing the distance the product moves and slowing down the movement speed.

[0005] The system consists of an incoming conveyor that receives products from the previous process, a stacking device, a discharge device that removes products, and a discharge conveyor that leads to the next process. The centerlines of each piece of equipment are aligned in a straight line, and the products are stacked by lifting them upwards and then placed on a foundation frame.

[0006] The incoming conveyor has a conveyor frame width of 240 mm and a belt width of 160 mm. Angle support plates measuring 20 x 20 x 1 mm are installed on both the left and right sides up to the stacking device to prevent items from flying off. A product holding plate is installed above the third product at the front, and a product detection sensor is mounted 2 meters behind the stacking area. Products up to 2 meters in length are constantly fed in using line pressure. TIFF2026101567000002.tif13170 units / minute: If two units are accumulated, two units are discharged to the next process 75 times / minute in a 0.8-second cycle.

[0007] For the incoming conveyor, which is 800 mm high, the introduction conveyor has a base frame that is 3000 mm long, 550 mm wide, and 300 mm high. The center of the conveyor is at a width of 200 mm, and the introduction conveyor extends to a position of 2000 mm, with a height of 500 mm. Beyond that, there is a 300 mm accumulation space, and the discharge belt is 700 mm long with a height of 625 mm. The specifications of the belt conveyor are a frame width of 240 mm with 20 x 20 x 1 mm angles attached to both sides, extending to the accumulation area, with a belt width of 160 mm, and a servo motor speed control system. The midpoint of 300 mm is designated as point O and the reference point. All attachments to the foundation frame are done by bolting 20x20 lumber from above and bolting mounting plates to the sides. The legs of the input conveyor are attached 1000 mm behind point O, and the legs of the output conveyor are attached 300 mm in front of point O.

[0008] A 550 x 160 x 8 mm plate is placed 64 mm in front of point O, perpendicular to the conveyor center at a 90° angle. The top 40 mm wide and 160 mm thick are cut to 2 mm and attached to a 20 x 20 mm square column on the base frame. This plate is designated as stop plate 1. A 450 x 160 x 8 mm plate is attached to the base frame 33.5 mm behind point O, perpendicular to the center line. A 440 mm long receiving rail is attached to this plate, and two sliders are passed through the rail. A 440 x 160 x 6 mm plate is attached to the sliders at positions 100 mm and 250 mm below the bottom. A 127 x 160 x 6 mm plate is attached perpendicular to the top of this plate. This plate is designated as stop plate 2. When stop plate 2 rises, it receives two products and acts as a stopper plate when it descends. The position 100 mm below this plate is the mounting position for the timing belt. At point O, parallel to the conveyor center, one 400 x 40 x 6 mm plate is erected on each side with a width of 60 mm from center to center. The timing belt pulley is attached at a mounting height of 50.350 mm, and the timing belt is clamped to a height of 100 mm using a clamp plate. By bolting this to the lower surface of stop plate 2, stop plate 2 can move up and down by 145 mm.

[0009] Four boards measuring 60mm wide, 680mm high, and 6mm thick are vertically mounted at positions 128mm to the left and right, and 64mm front and back, from the reference point O. The center of these 6mm thick boards is 624.5mm high, and the distance between them is 3.2 φ Drill a hole 6 mm deep. The rotating plate is a 128 x 60 x 3 mm plate, with a width of 50 mm and a 128 x 15 x 3 mm plate welded vertically at a 90° angle at a 15 mm position. On the back of this plate, the length is 5 + 128 + 5 mm, length 3 φ Weld the round bars together, and attach 5mm round bars to both sides as described in 3.2 above. φ When assembled into the metric holes, it becomes a rotatable support plate. Four mounting plates measuring 680 x 60 x 6 mm are used to attach the rotating plate, and a rotation stopper plate measuring 5.0 mm wide is provided at a height of 624.5 mm and a total length of 680 mm. Left and right ends of the rotating plate 3 φ Drill millimeter holes, attach hooks to the upper edges of the four 680 x 60 x 6 mm plates, and attach tension springs to the holes in the rotating plate to create a return action for the rotating plate. As stop plate 2 rises, the product is lifted, and the rotating plate in contact with the product rotates 90 degrees. At the point of rise, the rotating plate returns to its original position due to the force of the spring, and as stop plate 2 descends, the product is left behind on the rotating plate.

[0010] A 100 x 100 x 5 mm rectangular prism, 1600 mm long, is erected vertically at a position 220 mm to the left of point O, perpendicular to the direction of travel. At a position 1500 mm away, a 100 x 50 x 4 mm rectangular prism, 140 + 100 = 240 mm long, is welded horizontally at a 90° angle to the front and back of the 100 mm prism. An angle bracket of 50 x 50 x 5 mm is bolted to the top and bottom of the 100 x 50 x 4 mm rectangular prism. A plate measuring 600 mm long, 200 mm wide, and 6.5 mm thick, 300 mm upwards and 300 mm downwards, is bolted to the 50 mm angle bracket surface. A servo motor is positioned 250 mm below the center of the 200 mm wide plate. TIFF2026101567000003.tif16170 15 at a position 250 mm above φ Attach a millimeter-sized fixing pin and designate that point as O2.

[0011] A plastic board measuring 1100 mm in length, 40 mm in width, and 10 mm in thickness has six markings at the center of the width, 40 mm from the bottom edge, and 15 mm from the top and bottom. φ Drill one 15.1mm hole in each section, centered 500mm from the bottom edge. φ Drill one 1mm hole, assemble the pin at point O1 into this hole, then drill an elongated hole 15.1mm wide and 90mm high at a position 500mm above, assemble the pin at point O2 into this elongated hole, and the tip 6 φ A 120 x 50 x 5 mm press plate is inserted into the hole, and if that point is defined as point O3, then the 1100 mm plastic material becomes a lever plate with an O2O1 to O2O3 ratio.

[0012] Point O2 oscillates 150 mm up and down and 150 mm left and right, while point O3 oscillates 150 mm up and down and 300 mm left and right. If a product pushing plate is attached to point O3, when point O1 rotates once, point O3 rotates for the same amount of time as point O1, but the discharge section decelerates and performs a "pushing" operation at zero speed. Unlike other one-way extrusion devices that "throw" the product, this method pushes the product out at zero discharge speed.

[0013] In the state where the product from the previous process is pushed by the introduction conveyor and stopped by the stop plate 1, with the product detection sensor on, the product on the product stop plate instantaneously stops the servo motor of the timing belt by rising 10 mm (0.05 seconds). It stops more surely than the line pressure received by the product, is received on the side surface of the stop plate 2, and the two rising products become free in the 2 mm cut space of the plate of the stop plate 1 and are not affected by the pushing force at all. The moving speed V is L = (0.11 + 0.0145) × 2 + 0.128 = 0.377 meters. The time T is 0.8 - 0.05 = 0.75 seconds, and V = L / T, 0.398 ÷ 0.75 = 0.50 m / second = 30.1 m / minute and the moving speed is 45 m / minute or less. When the product accumulation method is the lateral movement method, the speed becomes fast, but it becomes slow in the vertical movement. By setting the line pressure to "0", it is a more stable method. In the case of two-stage accumulation, for two stackings, the discharge is once.

Embodiment for Carrying out the Invention

[0014] The product with an outer dimension of length 230 mm, width 110 mm, and height 64 mm is reversed by 90 degrees at the discharge part of the previous process packaging machine. The 110 mm width dimension is changed to the vertical direction, and the 64 mm height is changed to the horizontal direction in contact with the belt. The two products with dimensions of 230×64×110 mm are accumulated in a way that the products are discharged at 150 pieces / minute and accumulated at 75 times / minute with a 0.8-second cycle.

[0015] The conveyed conveyor is composed of an incoming conveyor, an accumulation device, a discharge device, and an outgoing conveyor with a height of 800 mm. It is installed and fixed on the upper surface of the foundation base with a height of 300 mm by the stacking accumulation device in the vertical height direction on the center line.

[0016] Belt frame width 240 mm, belt width 160 mm, loading belt, unloading belt In TIFF2026101567000005.tif12170, a product pressing plate and a loading conveyor are installed above the inlet part of the integrated device of the loading conveyor. A product detection sensor is installed 2,000 mm in front. The product is pooled at this position and the line pressure acts to push the product into the integrated device. The loading conveyor has a height of 500 mm and the discharge conveyor has a height of 638 mm. They are installed on the foundation pedestal at a level of 300 mm. The foundation pedestal has a length of 3,000 mm, a width of 550 mm, a height of 300 mm, a 200 mm pedestal, and an adjustment screw part with a height of 100 mm. It has a structure of 200 on the right and 350 on the left on the operator side in the advancing direction. 20×20 angle bars with the required length are screwed on from the upper side parallel or perpendicular to the center line on the iron plate of the foundation pedestal, and all mounting plates are attached by bolting to the side of the 20 - angle.

[0017] Between the loading conveyor and the unloading conveyor, a reference point O is determined at a position 150 mm from the mid - point of 300 mm in the integration part. The feet of the loading conveyor are installed 1,000 mm behind this point, and the feet of the unloading conveyor are installed 300 mm in front. Point O is also the common point of 2150 of the pedestal length of 3,000 and the 200 - point of the 550 width. 4 plates with a height of 680 mm, a width of 60 mm, and a thickness of 6 mm are vertically attached at positions parallel to the conveyor center and 64 mm in width, 120 mm left and right from point O, and 64 mm front and back, for a total of 4 pieces. A product receiving rotating plate with a width of 128 mm is attached at a height of 618.5 mm for a total of 128 mm (64 mm + 64 mm). In order to attach the product receiving plate, 6 - mm - deep 3.2 - mm holes are drilled at a position 3 mm from the center of the 6 - mm - thick plate. The product receiving plate has a width of 128 mm, a length of 50 mm, a thickness of 3 mm, and 50 mm φ is welded to a 138 - mm round bar with 3.2 TIFF2026101567000006.tif12170 (5 + 128 + 5) mm 3 φ and assembled into a 3.2 - mm hole. 3 - mm holes are drilled at positions 5 mm left and right at the tip of the 50 - length part. φ For the 4 plates of 680×60×6 mm, 3.2 - mm holes are drilled φ and the rotating plate of 128×50×3 is assembled into the 3.2 - mm hole φ φ ​When the round bar is assembled, it becomes a rotating plate for receiving the product. A rotation stopper plate is attached to the upper side of the rotating plate at the 623 mm position of the 680 mm plate, and a spring stopper hook is attached at the 670 mm position. φ By attaching millimeter holes and tension springs, it becomes a product support plate.

[0018] From point O, a 100 x 100 x 5 mm rectangular prism with a height of 1600 mm is erected vertically at a position 220 mm to the left and perpendicular to the direction of travel. At 1500 mm, two 100 x 50 x 4 mm rectangular prisms with a length of 140 + 100 = 240 mm are welded horizontally at a 90° angle front to back, narrowing the 100 mm rectangular prism. A 50 x 50 x 5 mm angle with a length of 200 mm is bolted to the tip of the prism's 50 mm surface. From the midpoint of the 100 mm rectangular prism at 50 mm, at a position of 1500 mm, plates with a length of 600 mm, a width of 200 mm, and a thickness of 6.5 mm are bolted to the 50 mm surface of the 50 x 50 x 5 angle, 300 mm above and 300 mm below, at the midpoint of 100 mm, 250 mm below and 200 mm in width. TIFF2026101567000007.tif16170600×200×6.5 mm board, 15 at a position 250 mm above the board φ Attach a millimeter-sized fixing pin and designate that point as O2.

[0019] A sheet of plastic material (MC nylon) measuring 1100 mm in length, 40 mm in width, and 10 mm in thickness has six markings at the 40 mm markings from the bottom edge, 20 mm above and below it. φ Drill two holes, 500 mm above the bottom edge, at a position of 15.1 φ Drill a hole in millimeters, then drill a long groove 500 mm above and below, with a width of 90 mm and a width of 15.1 mm, and then point O1 and 15.1 φ The tip section 6 is assembled with two holes and a 15.1mm wide elongated hole. φWhen the extrusion plate 120 x 50 x 5 is attached to the hole, one rotation of the servo motor at point O1 causes point O2 to move up and down 150 mm and swing left and right, and point O3 moves in an elliptical motion of 150 mm up and down and 300 mm left and right. The 1100 mm long extrusion plate performs a box motion of 300 mm left and right and 150 mm up and down with one rotation of the servo motor, and at the product extrusion discharge point at point O3, the product is pushed out at a speed of "0". Compared to the reciprocating motion pushing method of a conventional extrusion device, this is a stable moving method, and the return process passes over the product introduced to the next process and returns to the starting point in a one-box motion system.

Two units are stacked together, and the resulting 230 x 128 x 110 mm products are then transported to the next process via a belt conveyor at a speed of 75 units per minute. (1) The height of the input conveyor is 800 mm, and a base frame measuring 3000 x 550 x 300 mm is provided in the accumulation section, with the center line of the belt at a position of 200 mm at a width of 550 mm, the input conveyor section being 2000 mm long, the accumulation section being 300 mm long, and the discharge conveyor section being 700 mm long.

(2) At the accumulation section, a plate measuring 550 mm in length, 160 mm in width, and 8 mm in thickness is mounted 64 mm in front of point O, with 2 mm cut off the tip of the 550 mm length and 40 mm width and 160 mm width, and mounted vertically perpendicular to the conveyor center. This plate is designated as stop plate 1. At 33.5 mm behind point O, a 450 x 160 x 8 mm plate is mounted vertically perpendicular to the conveyor center.

A 127 x 160 x 6 mm plate is attached at a 90° angle perpendicular to the top of the plate. This plate is designated as stop plate 2. This stop plate 2 is used when the product rises. The two product receiving plates have sides that act as stop plates during upward and downward movement. A timing belt with a servo motor for vertical movement is installed 100 mm below these stop plates. One 400 x 40 x 6 mm plate is mounted parallel to each other on the left and right sides, 60 mm to the left and right of the center parallel to the conveyor center O point, at a height of 50.350 mm. φ A 50mm wide timing pulley is installed, and the timing belt is clamped to a height of 100mm using a clamp plate. The stop plate 2 is attached to the lower part of the surface that contacts the product during up and down movement, allowing for a vertical movement of 145mm. Four 680 x 60 x 6 mm plates are vertically attached to the base frame at positions 64 mm in front of and behind the center of the conveyor at point O, and 120 mm in the width direction. A product receiving plate is installed in the 128 mm gap between this plate and the four plates designated as plate 1. This plate serves as a receiving plate when stop plate 2 rises and falls, and 3.2 is located at a position 624.5 mm from the inner side of plate 1. φ If you drill a hole 6 mm deep, attach a spring mounting hook to the top of the plate at a height of 670 mm, one on each side for a total of four, then attach a stopper plate at a height of 629 mm on plate 1, and at a position of 23 mm on the 127 x 60 x 3 mm plate, the product receiving plate will be 128 x 50 x 3 mm, and weld a 128 x 15 x 3 mm plate at a position of 15 mm on the 50 mm width, on the back side, 3 φ Welding 5 + 128 + 5 = 138 mm long round bars together will create a spring attachment point at the 45 mm position on a 50 mm wide board. φ If you make holes on both sides of the board, the four pieces of board 1 will be 3.2 φ By attaching a hook to the hole, pulling it, and then attaching four springs, it becomes a receiving plate. (3) The discharge device consists of a 100 x 100 x 5 mm rectangular prism erected vertically at a height of 1600 mm at a position 220 mm to the left of point O, a 100 x 50 x 4 mm rectangular prism with a length of 240 mm is welded horizontally to the 100 mm square prism at a height of 1500 mm, a 50 x 50 x 5 mm angle with a length of 200 mm is bolted to the tip of the rectangular prism, and a 600 x 200 x 6.5 mm plate is bolted to the angle 300 mm above and 300 mm below, a servo motor is located at the bottom of the plate at a position 250 mm above and below the center width of the plate, and above At the center of a 1100×40×10 mm plastic plate, 6 holes with a diameter of 6 mm are drilled at positions 20 mm above and below the lower end by 40 mm. φ A hole with a diameter of 15.1 mm is drilled at a position 500 mm from the lower end. φ At a position 1000 mm from the lower end, a slot with a length of 90 mm, a width of 15.1 mm and upper and lower parts is drilled. The 15.1 mm hole and the O φ point pin are assembled with the 15.1-width slot and the O １ point pin. A push-out plate with dimensions of 120×50×5 mm is attached to the 6 ２ holes at the tip with a diameter of 6 mm. If that point is the O φ point, when the 150 φ diameter disc rotates once, the plate swings up and down by 75 mm and left and right at the O ３ point. The O １ point performs an elliptical motion of 150 mm up and down and 300 mm left and right. The 1100 mm plate works on the principle of a lever. The 150 φ diameter disc rotates at a constant speed, but the O ２ point accelerates in the upper and lower parts with a width of 150 mm and decelerates greatly at both ends with a width of 300 mm left and right. The speed of the push-out plate becomes "0". In the discharge method of decelerating greatly, the push-out plate rises and returns to the original start position. ３ The O φ point performs an elliptical motion of 150 mm up and down and 300 mm left and right. The 1100 mm plate works on the principle of a lever. The 150 ３ diameter disc rotates at a constant speed, but the O Products discharged from the packaging machine in the previous process are transported by an introduction conveyor, and the products receive line pressure on the lower 10 mm surface of stop plate 1. When a sensor installed at the entrance of the introduction conveyor turns "on", stop plate 2 starts to rise and receives line pressure on its side. At a position 10 mm higher, the product on stop plate 2 becomes free of line pressure at a 2 mm cut on the side of stop plate 1, and the product rises and moves to a receiving plate that is rotated 90 degrees, receiving line pressure on its side as stop plate 2 returns to its starting position. A simple single system characterized by the fact that the line pressure on the two products is eliminated during the rise, significantly reducing the chance of trouble occurring.
