Description

Technical Field

[0001] The present invention relates to the technical field of propellant production, and particularly to a device for transporting and arranging propellant strips. Background Art

[0002] Propellants are widely used in weapon systems and aerospace systems, and are an indispensable key foundation for weapon ammunition or aircraft during launch and propulsion. The regularity of the morphology of propellant grains directly affects the loading performance of propellants.

[0003] Currently, the cut surfaces of produced propellant grains often have the defect of inclined mouths, which is mainly due to the non-parallel arrangement of propellant strips before entering the cutting machine.

[0004] In the current process of propellant production, the propellant strips are mainly arranged in parallel by manual means. When the workers are fatigued, the effect of arranging the propellant strips in parallel significantly decreases, and propellants are somewhat dangerous. In addition, manual arrangement of propellant strips also has the disadvantage of low efficiency.

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0037] See Figure 1 , Figure 2 , Figure 3 , a medicine strip conveying and sorting device provided by an embodiment of the present invention. As Figure 1 shown, the device may include:

[0038] Table 1 and a conveyor belt 2, a comb bar mechanism 3, a pressing conveyor belt 4, and a medicine cutting mechanism 5 all connected to the table 1; the comb bar mechanism 3, the pressing conveyor belt 4, and the medicine cutting mechanism 5 are arranged in sequence along the running direction of the conveyor belt 2;

[0039] The conveyor belt 2 is used to convey several strips of to-be-cut propellant medicine strips forward;

[0040] The comb bar mechanism 3 includes several comb teeth 31, and the comb teeth 31 are used to embed between two adjacent to-be-cut propellant medicine strips to comb the to-be-cut propellant medicine strips parallel;

[0041] The pressing conveyor belt 4 is used to jointly convey the to-be-cut propellant medicine strips combed parallel with the conveyor belt 2 forward;

[0042] The medicine cutting mechanism 5 is used to receive the to-be-cut propellant medicine strips that have been combed and conveyed by the pressing conveyor belt 4 and the conveyor belt 2, and perform a cutting process.

[0043] For the medicine strip conveying and sorting device provided by the embodiments of the present application, during the forward conveyance of the to-be-cut propellant medicine strips, several comb teeth 31 can automatically comb the to-be-cut propellant medicine strips, so that the to-be-cut propellant medicine strips entering the pressing conveyor belt 4 and the medicine cutting mechanism 5 are combed into a parallel state, thereby ensuring that there are no defects such as beveled edges after the medicine cutting mechanism 5 cuts the medicine.

[0044] In order to enable the comb bar mechanism 3 to be lifted, as Figure 2 shown, an embodiment of the present application can further provide that the comb bar mechanism 3 further includes two guide shafts 32, a cylinder mounting plate 33, a cylinder 34, and a comb tooth mounting plate 35; one end of each of the two guide shafts 32 is connected to the table 1 and is located on both sides of the conveyor belt 2; the cylinder mounting plate 33 is connected to the other ends of the two guide shafts 32; the cylinder 34 is connected to the cylinder mounting plate 33; the comb tooth mounting plate 35 is located below the cylinder mounting plate 33 and is cooperatively connected to the two guide shafts 32, and the piston rod of the cylinder 34 is connected to the top of the comb tooth mounting plate 35; a plurality of the comb teeth 31 are uniformly distributed along the running direction perpendicular to the conveyor belt 2 and are all connected to the bottom of the comb tooth mounting plate 35.

[0045] Furthermore, the comb tooth mounting plate 35 is cooperatively connected to the guide shaft 32 through an oil-free bushing 36. The guide shaft 32 is connected to the table 1 through a guide shaft mounting seat 37. The front end of the comb tooth 31 has a round head structure.

[0046] To improve the production capacity of pelletizing, the medicine bars are usually stacked at certain intervals, so there will be a sudden change in thickness at the stacking position of the medicine bars sent from the upstream. For this reason, the comb bar mechanism 3 should have the function of timely avoiding the stacking position of the medicine layer. For this purpose, an embodiment of the present application can further provide a thickness mutation detection mechanism 6 connected to the table 1, and the thickness mutation detection mechanism 6 is located upstream of the comb bar mechanism 3; the thickness mutation detection mechanism 6 is used to detect whether the medicine bars to be cut and launched are stacked; so as to determine whether a plurality of the comb teeth 31 are embedded between two adjacent medicine bars to be cut and launched according to the detection result.

[0047] Specifically, as Figure 3 shown, the thickness mutation detection mechanism 6 includes a guide rod cylinder 61, a cylinder mounting frame 62, an optical fiber sensor 63, an optical fiber sensor mounting frame 64, and a roller 65; the cylinder mounting frame 62 is connected to the table 1; the guide rod cylinder 61 is connected to the cylinder mounting frame 62 and the piston rod of the guide rod cylinder 61 extends and retracts in the vertical direction; the optical fiber sensor mounting frame 64 is connected to the piston rod of the guide rod cylinder 61; the optical fiber sensor 63 and the roller 65 are both connected to the optical fiber sensor mounting frame 64.

[0048] The signal detection range of the optical fiber sensor 63 is smaller than the distance between the optical fiber sensor 63 and the lower edge of the roller 65, and the distance between the optical fiber sensor 63 and the lower edge of the roller 65 is smaller than the mutation thickness at the stacking position of the medicine layer.

[0049] As Figure 4As shown in the figure, the range within the triangle (which is a triangle in a two-dimensional diagram but actually a conical shape in three dimensions) is the detection range of the fiber optic sensor. Within this range, if there is a medicine strip, the fiber optic sensor will generate a signal. The maximum distance of this range is set as A mm, the vertical distance dimension from the fiber optic sensor to the lower edge of the roller is B mm, and the sudden change in thickness at the medicine layer stacking position is set as C mm. Since B is greater than A, when there is only one layer of medicine strip 71, the fiber optic sensor will not detect a signal because there is a medicine strip directly below. Since C is greater than B, when there are two layers of medicine strip 72, there must be a medicine strip at the medicine layer stacking position that can enter the detection range of the fiber optic sensor. Therefore, this mechanism can detect sudden changes in thickness.

[0050] To further improve the linkage function between the comb strip mechanism 3 and the thickness mutation detection mechanism 6, an embodiment of the present application can also provide a controller. Both the thickness mutation detection mechanism 6 and the comb strip mechanism 3 are electrically connected to the controller, and the controller is used to perform the following operations:

[0051] Receive the detection signal sent by the thickness mutation detection mechanism 6;

[0052] Control the comb strip mechanism 3 to drive a plurality of the comb teeth 31 to rise and control the guide rod cylinder 61 to drive the fiber optic sensor mounting bracket 64 to rise;

[0053] After an interval of the target time, control the comb strip mechanism 3 to drive a plurality of the comb teeth 31 to descend and control the guide rod cylinder 61 to drive the fiber optic sensor mounting bracket 64 to descend.

[0054] It can be understood that the pressing conveyor belt 4 provided in the embodiment of the present application can adopt relevant conveying structures in the prior art that can achieve the function of pressing the medicine strip. For example, in one implementation manner, the embodiment of the present application can provide that the pressing conveyor belt 4 includes a lifting drive assembly connected to the table 1.

[0055] The medicine strip conveying and sorting device provided by the embodiment of the present application will be introduced in detail below.

[0056] As Figure 1 shown, the automatic medicine strip conveying and combing device specifically includes a transmission belt 2, a thickness mutation detection mechanism 6, a comb strip mechanism 3, a pressing conveyor belt 4, a medicine cutting mechanism 5, and a table 1. Through the combined action of these devices and mechanisms, the automatic combing of the medicine strip is realized; the thickness mutation detection mechanism 6 can detect the sudden change in the thickness of the upstream medicine strip in a timely manner, so that the comb strip mechanism 3 can be lifted in a timely manner to avoid the position where the medicine strips are stacked; when combing the medicine strips, after the comb strip mechanism 3 is lowered, it remains stationary, and the medicine strips move downstream under the combined action of the transmission belt 2 and the pressing conveyor belt 4, thereby realizing the function of combing the medicine strips parallel.

[0057] In the existing process, to increase the production capacity of pelletizing, the medicine strips are usually stacked at certain intervals. Therefore, there is a sudden change in thickness at the stacking position of the medicine strips sent from upstream. For this reason, the combing mechanism 3 should have the function of avoiding the stacking position of the medicine layer in a timely manner.

[0058] The operation process of this device includes:

[0059] The thickness mutation detection mechanism 6 detects the stacking of the medicine strips coming from upstream, and the thickness mutation detection mechanism 6 and the combing mechanism 3 lift up; after a certain delay, the stacking position of the medicine strips is conveyed under the pressing conveyor belt 4 by the conveyor belt 2, and the medicine strips will be sent to the downstream medicine cutting mechanism 5 under the combined action of the pressing conveyor belt 4 and the conveyor belt 2; subsequently, the combing mechanism 3 is lowered, and the comb teeth 31 of the combing mechanism 3 are embedded into the gaps of the medicine strips, and the medicine strips are still conveyed downstream under the action of the pressing conveyor belt 4 and the conveyor belt 2, so that the comb teeth 31 of the combing mechanism 3 can realize the function of combing and parallelizing the medicine strips. In addition, when the combing mechanism 3 is lowered, the thickness mutation detection mechanism 6 will also be lowered to continue to detect whether there is stacking of medicine strips upstream of the combing mechanism 3.

[0060] The structure of the thickness mutation detection mechanism 6 is as Figure 3 shown: The thickness mutation detection mechanism 6 is composed of a guide rod cylinder 61, a cylinder mounting bracket 62, an optical fiber sensor 63, an optical fiber sensor mounting bracket 64, and a roller 65. The roller 65 and the optical fiber sensor 63 are both mounted on the optical fiber sensor mounting bracket 64. The detection range of the optical fiber sensor 63 is adjusted to A mm (A mm is less than the mutation thickness at the stacking position of the medicine layer), and at the same time, the vertical height difference between the optical fiber sensor 63 and the lower surface of the roller 65 is slightly greater than A mm. The optical fiber sensor mounting bracket 64 is mounted at the end of the guide rod cylinder 61, and the guide rod cylinder 61 is mounted on the cylinder mounting bracket 62.

[0061] This mechanism realizes the thickness mutation detection in the following way: When the cylinder 34 presses down, the roller 65 contacts the medicine strip. At this time, the distance between the optical fiber sensor 63 and the medicine strip is greater than A mm, and there will be no detection signal. When the stacking position of the medicine strips from upstream is conveyed within the range of A mm from the optical fiber sensor, the optical fiber sensor 63 will have a detection signal, thus realizing the function of thickness mutation detection.

[0062] The structure of the combing mechanism 3 is as Figure 2As shown in the figure, the comb bar mechanism 3 is composed of a cylinder mounting plate 33, a cylinder 34, a guide shaft 32, an oil-free bushing 36, a guide shaft mounting seat 37, comb teeth 31 and a comb tooth mounting plate 35. The end of the comb teeth 31 has a round head structure to facilitate reducing the friction force when the comb teeth 31 are inserted into the gap of the medicine strip and prevent the comb teeth 31 from scratching the transmission belt 2. The spacing of the comb teeth 31 is determined by the friction force between the comb teeth 31 and the medicine strip when combing the medicine strip. When the friction force is large, the spacing of the comb teeth 31 can be appropriately increased. The comb teeth 31 can perform the actions of lifting and lowering under the action of the cylinder 34.

[0063] The medicine strip conveying and sorting device provided by the present application combs the bent medicine strip through the comb teeth and the pressing conveyor belt, improves the winding and bending states that occur during the conveying process of the medicine strip, enables the medicine strip to be conveyed in an approximately straight state in the subsequent medicine cutting process, can effectively reduce the number of beveled mouths of the finished medicine grains, and improves the quality and yield rate of the finished medicine grains. It can realize the function of combing the medicine strip parallel, so as to achieve the purpose of replacing humans with machines, reducing safety risks, and improving the combing quality and efficiency.

[0064] At the same time, through the comprehensive application of simple components such as guide rod cylinders, fiber optic sensors and rollers, the function of detecting thickness mutation can be realized at a relatively low cost, so that the stacking position of the medicine strip can be recognized in time, and the comb bar mechanism can avoid it in time.

[0065] In addition, the end of the comb teeth is round to facilitate reducing the friction force when the comb teeth are inserted into the gap of the medicine strip and prevent the comb teeth from scratching the transmission belt.

Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the said element.
