Description

Technical Field

[0002] The main packaging container for ketchup is a conical iron drum with a capacity of 215 liters or 225 liters. As an outer packaging product, the conical drum can be stacked together during transportation and storage, which can significantly save transportation costs and storage space. Therefore, it is becoming more and more widely used. At present, the thickness of the base plate of domestic conical drum products is 0.8 to 1.5 mm. The material cost accounts for more than 80% of the product cost. The conical drum is a painted drum with a conical opening. The inner diameter of the drum bottom is 516 mm. The drum body and bottom cover are of the same thickness. The conical drum is formed by cutting thin plates, winding and welding them together, and then combining them with the drum bottom and top cover.

[0003] At present, in the processing of barrel bottoms, the width of the base plate is generally selected to match the diameter of the barrel bottom after punching, which will cause waste of raw materials after stamping. Alternatively, a swing feeder is used to perform punching and blanking by two punching machines, which requires increasing the working frequency of the punching machine. This not only places high requirements on the positioning accuracy of the feeder, but also on the punching machine, making subsequent maintenance more difficult. Summary of the Invention

Figure 1 The layout direction is determined by the

[0022] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0023] Example 1: As shown in the attached Figures 1 to 6 As shown, the barrel bottom production device of the conical barrel includes an unwinding machine 1, a leveling machine 2, a feeder 3, a first punch 4, a second punch 5, a third punch 6, a fourth punch 7 and a left-right conveyor. The feeder 3, the leveling machine 2 and the unwinding machine 1 are arranged on the left side of the conveyor from right to left, the first punch 4 and the second punch 5 are arranged on the left and right sides of the conveyor, the third punch 6 is provided on the front side of the conveyor corresponding to the position between the first punch 4 and the second punch 5, and the fourth punch 7 is provided on the front side of the conveyor corresponding to the right side of the second punch 5. The first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 are provided on the front side of the conveyor corresponding to the right side of the second punch 5. The punch 6 and the fourth punch 7 have the same structure. The distance between the left side of the first punch 4 and the left side of the second punch 5 is a first distance. The distance between the left side of the third punch 6 and the left side of the fourth punch 7 is a second distance. The first distance and the second distance are the same. The feeder 3 is used to move the first end of the steel coil on the unwinder 1 to the right on the upper side of the conveyor for multiple consecutive times. The distance that the first end of the steel coil moves each time is the same as the first distance. The first punch 4 and the third punch 6 are used to punch holes in the surface of the steel coil. The second punch 5 and the fourth punch 7 blank and punch the steel coil to form a circular barrel bottom.

[0024] According to the requirements, the unwinding machine 1 is an existing well-known technology, and the model of the unwinding machine 1 is KJ-1600*12T. The leveling machine 2 is an existing well-known technology, and the model of the leveling machine 2 is XP-1380*11-5. The leveling machine 2 makes the surface of the steel coil smoother. The feeder 3 is an existing well-known technology, and the model is a servo feeder 3 of NCF-1300. The feeder 3 makes the direction of each movement of the first end of the steel coil the same, and will not swing back and forth. It can also make the distance each movement of the first end of the steel coil the same as the first distance. There is a distance between the feeder 3, the leveling machine 2 and the unwinding machine 1, so that a waiting area can be formed. A pit can be set in the waiting area to increase the length of the steel coil in the waiting area. The arc buffer of the material passing through the waiting area can make up for the incomplete synchronization of the feeder 3, the leveling machine 2 and the unwinding machine 1. The steel coil with a width of 1100mm and a thickness of 0.5-0.8mm can be used in this application. The punching diameter of the circular barrel bottom in this application is 578mm. The front circular barrel bottom and the rear circular barrel bottom are staggered left and right. The distance between the front and back center axes of the two staggered circular barrel bottoms is 503.5mm to 504.5mm. The distance between the left and right center axes of the two staggered circular barrel bottoms is 291mm. The distance between the center axes of the two adjacent circular barrel bottoms in the left and right directions is 582mm, that is, the first distance and the second distance are both 582mm.

[0025] During use, the steel coil is installed on the unwinding machine 1, and then the first end of the steel coil passes through the leveling machine 2 and the feeder 3 in sequence and is located on the upper left side of the conveyor. By adjusting the feeder 3, a certain distance is maintained between the punching center of the first punch 4 and the rear side of the steel coil. The second punch 5 is adjusted so that the punching center of the second punch 5 and the punching center of the first punch 4 can coincide with the punching center of the steel coil when punching. At the same time, a certain distance is maintained between the punching center of the fourth punch 7 and the front side of the steel coil, so that the distance between the punching center of the fourth punch 7 and the first end edge of the steel coil is 10 mm. The third punch 6 is adjusted so that the punching center of the third punch 6 and the punching center of the fourth punch 7 can coincide with the punching center of the steel coil when punching. The arrangement makes the working frequencies of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 the same, and the dies of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 move downward at the same time to complete the stamping process, so that after each movement of the first end of the steel coil, the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 can complete the stamping process, thereby improving the processing efficiency of the barrel bottom. In the present application, the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 are staggered, and the surface of the steel coil can be staggered for stamping, which can improve the utilization rate of the steel coil, reduce the waste of steel coil materials, and reduce the production cost. At the same time, the staggered arrangement of the punches can save production space and facilitate the transportation of materials.

[0026] The above-mentioned conical barrel bottom production device can be further optimized and / or improved according to actual needs:

[0027] Example 2: As an optimization of the above example, as shown in the attached Figures 1 to 3 As shown, the distance between the left side of the first punch 4 and the left side of the third punch 6 is the third distance, and the first distance is twice the third distance.

[0028] During use, through such an arrangement, the working frequencies of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 are the same, and the dies of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 move downward at the same time to complete the stamping process. In this way, after each movement of the first end of the steel coil, the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 can complete the stamping process, thereby improving the processing efficiency of the barrel bottom. In this application, the distance between the central axis of the circular barrel bottom processed by the second punch 5 and the central axis of the circular barrel bottom processed by the fourth punch 7 in the front-to-back direction is 503.5mm to 504.5mm, the distance between the central axis of the circular barrel bottom processed by the second punch 5 and the central axis of the circular barrel bottom processed by the fourth punch 7 in the left-to-right direction is 291mm, and the distance between the central axes of the two adjacent circular barrel bottoms processed by the second punch 5 is 582mm, that is, the first distance and the second distance are both 291mm, so that the minimum distance between the outer sides of the two adjacent circular barrel bottoms is 4mm, which can save materials and reduce material costs.

[0029] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown, the conveyor includes a first roller conveyor line 8, a second roller conveyor line 9 and a third roller conveyor line 10. A shearing machine 11 is provided to the right of the fourth punch 7. The first roller conveyor line 8 is provided between the right side of the feeder 3 and the left side of the shearing machine 11. A first discharge port 17 is provided on the upper rear side of the first roller conveyor line 8 corresponding to the position between the second punch 5 and the fourth punch 7. A second roller conveyor line 9 is provided on the inner side of the rear of the first roller conveyor line 8 corresponding to the position of the first discharge port 17. The conveying direction of the second roller conveyor line 9 is from the upper left to the lower right. A second discharge port 18 is provided on the upper front side of the first roller conveyor line 8 corresponding to the position between the fourth punch 7 and the shearing machine 11. A third roller conveyor line 10 is provided on the inner side of the front of the first roller conveyor line 8 corresponding to the position of the second discharge port 18. The conveying direction of the third roller conveyor line 10 is from the upper left to the lower right.

[0030] According to the requirements, the first roller conveyor line 8, the second roller conveyor line 9 and the third roller conveyor line 10 are all existing well-known power roller lines. The adjacent two rollers are connected together by a sprocket chain drive. The models of the first punch 4, the third punch 6, the second punch 5 and the fourth punch 7 are all JH21-160. The first roller conveyor line 8 at the positions of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 are all provided with notches. The length of the rollers on the left and right sides of the notch is greater than the length of the roller at the notch position, so that the lower die of the punch can be installed. The lower side of the slider of the first punch 4, the second punch 5, the third punch 6 and the fourth punch 7 is installed with an upper die corresponding to the lower die, so that the first end of the steel coil can be repeatedly moved to the right between the upper die and the lower die. When the first end of the steel coil moves the first distance, the upper die moves downward and interacts with the lower die to realize punching, cutting and rib pressing on the surface of the steel coil after unfolding. The model of the shearing machine 11 is JB-2000.

[0031] During use, the setting of the first discharge port 17 and the second discharge port 18 can separate the circular barrel bottom formed after cutting from the waste. When the cut circular barrel bottom passes through the first discharge port 17 and the second discharge port 18, it falls on the upper left end of the second roller conveyor line 9 and the third roller conveyor line 10 respectively under the action of its own weight. In this way, the circular barrel bottom can be conveyed to the next process position by the second roller conveyor line 9 and the third roller conveyor line 10, which is convenient for further processing of the circular barrel bottom. There are multiple spaced punching holes on the surface of the cut plate. The setting of the shearing machine 11 can cut the waste moving to the right, which is convenient for the centralized collection of waste.

[0032] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 2 As shown, the width of the second discharge port 18 is the same as the width of the first discharge port 17, and both are larger than the radius of the barrel bottom.

[0033] During use, through such an arrangement, the circular barrel bottom cut by the second punch 5 and the fourth punch 7 moves to the right together with the waste material. When the right part of the circular barrel bottom moves to the first discharge port 17 and the second discharge port 18, the circular barrel bottom falls into the first discharge port 17 and the second discharge port 18 under the action of gravity, and is then conveyed to the bottom by the second roller conveyor line 9 and the third roller conveyor line 10, which can realize the automatic separation of the circular barrel bottom and the plate material and improve production efficiency.

[0034] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown, the right end of the second roller conveyor line 9 and the right end of the third roller conveyor line 10 are both provided with a fourth roller conveyor line 12 with a conveying direction from back to front, and each fourth roller conveyor line 12 is provided with a collecting tray 13 at the front end.

[0035] Depending on the needs, the fourth roller conveyor line 12 is a known technology. During use, the third and fourth punching machines 6 and 7 are located on one side near the central aisle of the factory building. In this way, the fourth roller conveyor line 12 transports the round barrel bottoms cut by the second and third punching machines 5 and 6 to a collection tray 13 near the central aisle. This makes the transportation of the round barrel bottoms cut by the second punching machine 5 more convenient. Alternatively, the fourth roller conveyor line 12 can be transported to the front end, and the six-axis robot arm or operators can place the round barrel bottoms on the collection tray 13.

[0036] Example 6: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown, a conveyor belt 14 is provided on the right side of the shearing machine 11, a waste collection box 15 is installed on the right end of the conveyor belt 14, and a pre-roller 16 for curling the outer edge of the circular barrel bottom is provided on the right side of the waste collection box 15.

[0037] According to the requirements, the conveyor belt 14 and the pre-winding machine 16 are both existing well-known technologies. The model of the pre-winding machine 16 is YJ-600. A tray for placing the bottom of the barrel is provided on the front side of the pre-winding machine 16. During use, by setting up the conveyor belt 14, the shearing machine 11 will cut the processed waste, so that the continuous mesh-shaped waste can be cut according to a certain length. The cutting frequency of the shearing machine 11 can be consistent with the punching frequency of the first punching machine 4, or it can be several times the punching frequency of the first punching machine 4. The pre-coiler 16 further processes the circular barrel bottom, and curls the outer edge of the circular barrel bottom to make a qualified barrel bottom, which is convenient for subsequently sealing and fixing the barrel bottom and the barrel body together. The pre-coiler 16 is set on the right side of the waste collection box 15, which can avoid the phenomenon of material accumulation caused by the rhythm of cutting the circular barrel bottom being faster than the rhythm of the pre-coiler 16, which can play a buffering effect and make the installation area more compact. Pre-coilers 16 can also be set at the front ends of the two fourth roller conveyor lines 12, and the collection tray 13 can be set in front of the pre-coiler 16.

[0038] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
