[Technical field]

[0001] TIFF2025069031000002.tif11161A field where the speed is 50 times per minute, the cycle is 1.2 seconds, and the product length is 160 mm, and a specified number of 7 pieces are accumulated and discharged to the next process. [Background technology]

[0002] (1) When accumulating 7 bottles, set the number of filling rows to 7, and when discharging, gather them into groups of 7. With this method, it is not possible to increase the amount by 8 or 9, but it is possible to increase the amount by 6 or 5. 7-row installation method (2) A 6 to 10-row filling machine is set up in one go, and the products are discharged onto a wide guided belt conveyor, and a pin conveyor with the same width as the film cutting width is set up at a right angle of 90 degrees. The timing is synchronized with each other, and the products jump into the gaps between the pitches of the pin conveyor in continuous operation. With this method, if the subsequent process stops, jamming problems are inevitable. The pin conveyor is lifted at an angle, and a product bucket and counter sensor are installed under the sprocket at the end to accumulate a set number of products. With this method, the drop is large, so the frequency of upside-down products is high, and it is difficult to connect to the subsequent process. (3) In the method of (2), the pin conveyor is stopped when the product is input, and the next product arrives 1.2 seconds later. TIFF2025069031000003.tif10170(1)(2)(3) do not show the capacity of the filling machine: [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication 2013-86827 [Patent Document 2] Patent Publication No. 62-28320 [Patent Document 3] Patent Publication No. 59-134128 [Patent Document 4] Patent Publication 2011-16541 [Patent Document 5] Patent Publication 2010-6919 [Patent Document 6] Patent Publication 2012-111505 [Patent Document 7] Patent No. 2017-178368 [Non-patent literature] Summary of the Invention [Problem to be solved by the invention]

[0004] (1) The height of the products discharged from the filling machine is low at 400 mm and the pitch is narrow at 57.15 mm, making it difficult to install a damper due to the limited space available. In addition, since good and defective products are mixed when the products are discharged, a defective product discharge device is required, and a damper is also required. (3) A structure was required that would prevent interference between the front, back, and sideways when the 14 rows of products were moved. (4) Because the center of gravity of the product is located at the top of the bag due to the vertical filling method, there is space above the bag. Measures were needed to prevent the product from tipping over due to the difference in height. (5) A method to solve the problem of the number of pieces being set to 7, but the number can be reduced to 6, but not increased (when set to 7)

[0005] (1) At the discharge section of the filling machine, a 14-row intermittent inclined conveyor rises to 1,000 mm, and a chute is installed with a first damper at a height of 950 mm and a second damper at a height of 870 mm to keep the material level as it falls. (2) A first damper is installed at the exit of the chute to absorb delays in the progress of the 14 rows, prevent the balls from falling upside down, and adjust the timing of the second damper when the balls are discharged. (3) A stacking device that has a second damper and stacks a set number of products. In the case of seven products, the stacking device receives seven products in 8.4 seconds. (4) The first and second dampers are both equipped with 15 double pipe shafts spaced 57.15 mm apart to accumulate waste by a drop (10 shafts is the limit due to volume). (5) It is only necessary to set the maximum number of bottles to 10 or less. Stacking of 10 to 20 bottles in a single row is possible if the filling machine specifications are 12-row, and multiples of 2, 3, or 4 are possible by installing a secondary stacking device at the time of discharge. (6) The 14-row discharge center shall be installed in a straight line, with the chute center, first damper center, second damper center and product bucket center all in the same row. (7) In the event of a defective product, all 14 rows of products are discharged at the outlet of the filling machine.

[0006] (1) Plates A and B are attached to the side frame of the lower product bucket conveyor in a 90° direction forward and backward across the damper width, making the first and second damper sections removable and adjustable from the outside when making adjustments. When operating with a large number of lines, a spare damper section can be provided and replaced, making it possible to outline maintenance with a narrow dimension of 57.15 mm. (2) The first damper has 15 double pipe shafts, 1234----13, 14, 15, and 15 in total. Of the 15 pipe shafts, 1-2 is 1 span, 2-3 is 2 spans, 3-4 is 3 spans, and so on, 13-14 is 13 spans, and 14-15 is 14 spans. Slat A is attached to the sprockets of the odd-numbered thin pipe shafts of (1)(3)(5)-----(11) and (13), and slat B is attached to the thick pipe sprockets of (2)(4)(6)----(12) and (14). For shafts 1 and 15, only the thin pipe slat is attached to shaft 1, and only the thick pipe slat is attached to shaft 15. A servo motor shaft is installed on the outside of 15 and a return shaft is installed on the outside of 1, and one sprocket each is installed for odd and even numbers. The first damper is controlled by one servo motor, and the second damper is installed in the same way.

[0007] Boards 1, 2, and 3 have four holes drilled in the front, back, top and bottom of each board, and a collar is sandwiched between them to make one piece. Plates 1 and 2 each have 15 clip bearings for thick pipes, and the third plate has clips for thin pipes. TIFF2025069031000004.tif15170The ring is embedded, and the thin pipe is held in rotation by a clip bearing on the third plate and a bush bearing embedded in the thick pipe.

[0008] When passing the chain over the sprocket attached to shaft 1 of the thin pipe from the top, and the sprocket attached to shaft 2 from the bottom to the top, shaft 1 should rotate in reverse clockwise and shaft 2 should rotate in forward clockwise, and so on until it has been passed through the 15th turn. For the sprocket on the thick pipe shaft, shafts 1 and 2 should rotate in reverse from the top to the bottom, and shaft 3 should rotate forward from the bottom to the top, and so on until it has been passed across shaft 15. Each chain should be an RS25 double chain with a pitch of 6.35 mm, and the sprocket should be a double-row sprocket with a 6.35 mm pitch, 13 teeth, and a return shaft should be attached to the outside of shaft 1 and a sprocket for the servo motor with a 6.35 pitch, 20 teeth, double-row sprocket should be attached to the outside of shaft 15, and they should rotate the specified angle.

[0009] The second damper is set in the same way as the first damper, and in order to increase the volume of the blades, a 40 mm plate is attached vertically at 90 degrees with the blade mounting shaft blade receiving plate part opened 20°, and installed in a state of 110 degrees volume, and when the servo motor is rotated at a specified angle, the damper will rotate at the specified angle and the product will drop and accumulate. The distance between the first damper, second damper and the bottom of the product bucket is each 80 mm, which is shorter than the length of the product to prevent it from being upside down.

[0010] The product bucket is discharged in 8.4 seconds with 7 intermittent movements of 2 buckets.

[0011] (1) By using a double pipe axis for the shaft, it is possible to stack 14 rows of products in a small space, and products are moved by drop. The opening and closing of the dampers is simplified by a single servo motor for all 14 rows of dampers. The drop distance is also shorter at 80 mm, instead of the product length of 140 mm, so the frequency of inversions is reduced, and the speed is slower at 1.2 second cycle, making it more stable. (2) The inclined conveyor lifts the container to a height of 1,000 mm and has 14 rows of dampers for processing, allowing for a compact installation. It is also possible to connect one or two filling machines together. (3) Three workers are required for one line, but even if two machines are operated, production volume will approximately double with just one additional worker, and further rationalization will be possible by utilizing 100% of the filling machine's capacity.

[Diagram 5] Layout diagram of two filling machines DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The stick filling machine outputs 50 products per minute at a speed of 14, with a cycle of 1.2 seconds, and the product dimensions are film cut width 57.15 mm, product length L 140 mm, width W 23.5 mm, and thickness H 7 mm. Products are discharged from a height of 400 mm in 14 rows, 50 times, at a speed of 700 products per minute. The products are received horizontally on an intermittent inclined conveyor, which rises to a height of 1000 mm and discharges them horizontally into the chute for the next process. The products are received by the first damper, and the specified amount of 7 products is accumulated by the second damper and discharged into the product bucket. The product bucket operates intermittently 2 buckets 7 times, and is discharged to the next process in 8.4 seconds.

[0014] Plates A and B are attached to the side frame of the lower product bucket conveyor at a 90 degree angle to the width dimension of Damper 1 and Damper 2. Damper 1 and Damper 2 are removable, and the center of the chute exit, center of Damper 1, center of Damper 2, and center of the product bucket are structured to form a straight line.

[0015] Damper 1 has 15 double pipe shafts with a pitch of 57.15 mm. Plates 1, 2, and 3 are sandwiched with collars with two holes drilled at the top and bottom of both ends, and secured with shaft screws. It is an integrated structure that can be removed. Plates 1 and 2 have an inner diameter of 10 mm with a pitch of 57.15 mm. φ 15 mm clip bearings are attached to each plate, 7 thin pipes are attached to 3 plates. φ 15 mm clip bearings are attached at 57.15 pitch to the front and rear ends of the thick pipe with an external diameter of 10 φ , inner diameter 7. 2φ 7. 2φ With hole processing 8.5 φ The depth of the hole is 10 mm, and the inner diameter is 7.2 mm. φ The bush bearing is embedded, and these two bush bearings and the clip bearing of the plate 3 are 7. φ The thin millimeter pipe is held at three points.

[0016] Double pipes 1, 2, 3----14, 15. The span 1-2 of the double pipes is defined as (1), the span 2-3 as (2), ----13-14 as span (13), and 14-15 as span (14). The spans (1)(3)(5)---(11)(13) are odd number A, and the spans (2)(4)(6)-----(12)(14) are even number B. A is defined as the thin pipe and B is the thick pipe.

[0017] Thin pipe, 7 φ Attach each sprocket to the shaft axis, and attach blade A to the odd-numbered (1)(3)-----(11)(13) span shafts. Thick Pipe 10 φAttach each sprocket to the shaft wheel, and attach blade B to the even-numbered (2)(4)---(12)(14) span shafts. The width of the blade is the shaft pitch of 57.15 mm divided into two equal parts, and the length is the product length.

[0018] Odd-numbered sprockets 1 are on the top, 2 are on the bottom, 3 are on the top, 4 are on the bottom, and so on up to 15. TIFF2025069031000005.tif12153The even-numbered sprockets are 1 and 2 on the top, 3 on the bottom, and 4 on the top -----If you pass the chain through to 15, 1 and 2 will rotate in reverse, 3 will rotate in the forward direction, 4 will rotate in reverse, and 5 will rotate in the forward direction. The dampers open and close when the servo motors of the odd group (1)(3)(5) ---(11)(13) and the even group (2)(4) ---(12)(14) rotate in the reverse or forward direction at the specified angle.

[0019] The first damper is discharged from the chute, absorbing speed errors of the product, shortening the drop distance and adjusting the time when the second damper is discharged. The second damper's product, drop, and opening / closing confirmation can be set. In order to increase the volume of the second damper, 40 mm plates are installed vertically on both blades A and B. A 40 mm plate is installed at an angle of 110° to set the damper in an open position at 20°.

[0020] The second dumper accumulates the specified number of seven pieces, and when completed, the pieces fall into the product bucket, which is then discharged within 1.2 seconds x 7 = 8.4 seconds using two intermittent bucket operations. Possibility of industrial use

[0021] This technology allows the full capacity of the stick filling machine to be operated, and by establishing a line, rationalization will progress further. It can also be widely used as a supplying device for the blades of an automatic supplying machine. [Explanation of symbols]
