Description

[Technical field]

[0001] This invention is in the field of a production system that produces pillow-packaged products, twist-packaged products, and 3-pack sealed-packaged products at high speeds of 600-1200 pieces / min, displays ( )g, and checks ( ) pieces with an auto-checker. [Background technology]

[0002] Pillow-packaged products, twist-packaged products, and 3-pack sealed-packaged products are discharged from the packaging machine at high speeds of 600-1200 units per minute. They are received in large bags or boxes, and weighed by an outline multi-row weighing machine before being bagged or boxed. To do this, the products are lifted by a lifter, weighed by an autoscale, transported, and bagged by a bagging machine. A check is then made by the filling machine, and the products are packaged in groups of 10 and packed into cardboard boxes. This requires space, equipment, and workers, and if there is variation in the weight of the products, the amount of packaging will increase. Most bagged confectioneries are produced using this production method. [Prior art documents]

[0003] Summary of the Invention

[0004] The packaging machine discharges 600-1200 products per minute, and the weight of each bag is changed from ( ) grams to ( ) pieces. An auto checker is used to check the bag weight. By changing to a production system, it is possible to streamline equipment and workers, and the work time and labor per 1000 can be reduced to 0.7-1.0 hours.

[0005] Product dimensions LWH, 1g product, 1200 products / min, 20 products / sec, 0.05 sec pitch, 1.4 times the product length L, 0.1m, 20 products / sec, 2m / sec, moving at a speed of 120m / min. Belt conveyor. Suction conveyor receives products. Suction conveyor is installed at the top of the moving section. Suction air pressure is 250~500mmHg. Blower is 2.5~7.5Kw. Belt conveyor (Fig.4, Fig.5) 4 rows horizontally at the center, 15mm pitch, 20 vertically around the entire surface. TIFF2025013084000002.tif21170 with 5mm wide holes. The damper plate has a 55mm wide hole with a pitch of 10mm and 5mm wide holes in the belt center. The damper is attached to the surface of the timing belt with servo motor by sandwiching the damper plate and a slightly wider plate on the upper side with the same shape as the lower timing belt mountain shape underneath, and fastening it with bolts and nuts at the four corners. The damper is attached by the force of the screws and the elasticity of the rubber to prevent loosening. The damper is attached to the packaging machine in two places. The receiving pitch is P. P2 is set to P, and P1 is set to the position of P+100 mm. A counter sensor is installed in front of the entrance of P2. 20. 20… 20 count signals are sent by the servo motor of the damper installed on P1, which is on / off. The product falls. It moves 100 mm in the opposite direction and, as soon as the product has fallen to P2, it is sent out at pitch P for the next process. The speed of the damper timing belt is 0.005 m ÷ 0.05 sec = 0.1 m / sec if it moves 5 mm in 0.05 sec. The speed is slower than the 120m / min product movement speed, which is 6m / min. The suction pressure of the suction conveyor varies depending on the shape and weight of the product. The wind pressure and volume are determined by testing. If the product is light at the receiving port from the previous process and is unstable due to the influence of wind, suction by 3-minute suction may be considered. The next process is the bagging machine, which can pack 10 items into boxes and cardboard boxes. If boxes are used, the boxes are packed using a cartoning machine, and then the boxes are packed directly into cardboard boxes.

[0006] The next process is the boxing machine. The cartoning machine is a double-unit type that can operate 30 times per double unit, 60 times per minute. The product weight is checked by an auto-checker, and the designated number of cardboard boxes are accumulated and packed into the cardboard boxes, completing the line.

[0007] In the case of 20 bags, 3 workers and 400 minutes of operation, the production volume is 60 x 400 = 24,000 bags per operation. 24÷(24,000÷1000)=24 / 24=1 In the case of 20 boxes, 2 workers and 400 minutes of operation, the production volume is 60 x 400 = 24,000 boxes per operation 16÷(24,000÷1000)=16 / 24=0.66≒0.7 Effect of the Invention

[0008] In the outline production method, products discharged from the packaging machine are received in large bags or boxes, stocked, weighed on a multi-row weighing scale with a lifter, transported, bagged with a single or double bagger, weight reconfirmed with an auto checker, boxed in 10 boxes, and packed into a specified number of cardboard boxes. This requires manpower and space for storage, and a lifter and multiple auto scales are required, as well as space and operators. In the inline method, a connected belt conveyor, a suction conveyor above the suction conveyor, and two damper discharge conveyors are required. Equipment costs are significantly cheaper, and labor can be saved, and the line's labor hours can be significantly reduced from 1.0 for 20 bags. [Brief description of the drawings]

[0010] Products discharged from the packaging machine at a speed of 1200 pieces / min are 1200 / 60=20 pieces per second, with 20 pieces discharged at 0.05 second intervals. If the receiving conveyor belt receives at a 10 cm interval, it will be 0.1 m in 0.05 seconds. If 20 pieces / sec, the speed will be 2 m / sec, or 120 m / sec. If the switching damper operates at 5 mm in 0.5 seconds, the speed will be slow at V=L / TV=0.005÷0.05=0.1 m / sec=6 m / min. The suction force of the suction conveyor is 250-500 mmHg, and an adsorption test is performed with a blower motor of 2.5-7.5 kW to determine the suction force. The counter sensor detects the specified number of products being transported by suction, 20.20...20, and the servo motors of dampers P1 and P2 open and close by turning on and off in sequence. The preceding products in P1 move 10 cm behind by one pitch, sending them to the next process as two rows of products at the same time as the products accumulated in P2. They are then bagged in a two-row vertical pillow packaging machine, the weight of the products is checked, and they are boxed in 10 pieces and packed into the specified number of cardboard boxes, and the system is completed. (The blower uses the intake and exhaust in reverse to become a suction source.) Explanation of symbols

Claims

[Claim 1] 600-1200 pieces are discharged from the packaging machine per minute. Pillow-packaged, twist-packaged, and three-sided sealed products are put into bags in a specified quantity. (A) The current method is to receive the bulk in large boxes and large bags at the exit of the packaging machine, weigh them with a multi-row outline scale, and put them into bags of a specified number of grams. (B) In contrast to this method, the products are received directly from the packaging machine on a conveyor belt, counted by a counter sensor, and put into bags of the specified number. If we change to an inline production system (1) the LWH dimension of the products discharged from the packaging machine is 30-70 mm, with a pitch of 1.4 times or more the L dimension, and the belt speed is 100 mm / piece, then 1200 pieces / minute will be 120 m / minute, or 2 m / sec. If there are 20 pieces in one bag, then 1200 ÷ 20 = 60 bags / minute. A method of dividing a product traveling at a speed of 120 m / min with a pitch of 100 mm into 20.20...20 pieces is to use a suction conveyor that is moving at the same speed as the belt conveyor above the product. (2) The suction conveyor is 100 mm wide and has 4 rows with a pitch of 15 mm horizontally and 4 rows with a pitch of 20 mm vertically, with the first and third rows being the same. The second and fourth rows are 10 inches closer to the center than the first and third rows. In the suction chamber. The bottom surface of the belt that comes into contact with the product is 100mm wide, with holes drilled all over the bottom at 55mm width and 10mm pitch vertically, with 5mm width. The damper is 100mm wide and 200mm long (10+100+90), with 10mm forward projection, the belt width is 100mm, the mounting width is 90mm, and the center of the center part of the 100mm belt width is 55mm. The bottom surface of the frame is machined with holes of the same dimensions at 10mm pitch and 5mm width, and the discharge part P １ , P ２ A hole is made on the lower side of both side panels that contact the bottom surface of the part, 3 mm (thickness of damper plate T) and 120 mm wide at the center to pass the damper plate through. A damper plate is passed through the hole, and a timing belt with a servo motor is attached. A plate with the same dimensions and shape as the timing belt mountain shape, wider than the timing belt width, is used. Two holes are drilled at the top and bottom, and fastened with a hole nut. The force of the screw and the elasticity of the timing belt are used to prevent loosening, and the timing belt with servo motor is attached to the side of the suction chamber. The suction force of the suction conveyor is constant, with an air pressure of 250 to 500 mmHg and an air volume of 2.5 to 7.5 kW blower. The air pressure and volume vary depending on the shape and weight of the product. A test is performed to determine the conditions. For a 0.05 second delay, the damper should move 5 mm in 0.05 seconds. The moving speed V = L ÷ T, so V = 0.005 / 0.05 = 0.1 (m / s) = 6 (m / s). If the suction is stopped within one cycle, the product will fall and can be accumulated, and the opening and closing speed should be determined. If we use a method to slow down from 120 m / min, (4) the damper installation position is. The pitch P of the cartoning machine and the supply machine of the bagging machine in the next process is the basis. P １ The position of is 100 mm ahead of the position of P. ２ The position of P is the same as the accumulation position. The damper mounting position is the same. P １ After 100 mm of accumulation, return it to P. ２ At the same time as the accumulation of ２ Push out in the 90° direction and perform P ２ Before proceeding, install the counter sensor and count 20, 20, 20... and set 20 for No. 1 to P. １ The second one is P ２ Damper P １ The servo motor is turned on to pass and off to close. The second 20 are P ２ When the servo motor of the damper is turned on and off, the product falls. １ Move 100 mm and press P. ２ PP at the same time as accumulation is completed ２ 20 products of P P ２ At the same time, they are discharged at a 90° angle. Two rows at 30 times per minute. When discharged at P pitch, (5) they are bagged and boxed. In the case of bagging, if 10 more pieces are placed in the inner box, it will not be 3, and the specified number is pushed into the cardboard box. In the case of boxes from the cartoning machine, they are placed directly into the cardboard box. Therefore, in the case of bagging, an additional worker is required, and the weight of the individually packaged bags and boxes is checked with an auto checker, and the production line system is completed with the number of pieces being managed. (6) Productivity of 20-piece subdivision line at 1200 pieces / min. The working hours and man-hours for 1000-piece production are 1200-piece line. 60 pieces / min. Actual operating time is 400 minutes for 24,000-piece production. Packing: 3 people 24 hours 24 ÷ (24000 ÷ 1000) = 1 Packing in boxes 2 people 16 hours 16÷(24000÷1000)=0.66≒0.7 The bagging line requires 1 man-hour, and the boxing line requires 0.7 man-hours, making this a method that features a more streamlined production system compared to the current outline method.
