Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery, and in particular relates to a limit counting device. Background Technology

[0002] The civil explosives industry is highly regulated due to its unique nature, with a strict licensing system for practitioners. Based on the core safety requirements of the industry, the packaging of explosive cartridges is subject to stringent regulations and standards. Against this backdrop, the accurate counting and orderly arrangement of explosive cartridges using mechanical equipment has become a crucial step in the packaging process for civil explosives.

[0003] Currently, traditional drug roll counting devices typically include a guide device, such as an arc-shaped baffle, between the arrangement conveyor and the counting conveyor to achieve orderly arrangement of the drug rolls. However, this structure has significant shortcomings. When the drug rolls fall to the counting conveyor, it is difficult to achieve reliable and regular rolling posture control. This can easily lead to phenomena such as the drug rolls falling skewed, missing their target, or multiple rolls falling at the same time, which seriously affects the accuracy of counting. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the deficiencies and defects mentioned in the background art above, and to provide an explosive cartridge limit counting device that has controllable rolling posture, is simple to operate, can accurately count explosive cartridges of different types and specifications, and has a short production changeover time.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0006] A limiting and counting device for explosive cartridges includes an arranging conveyor mechanism and a counting conveyor mechanism arranged sequentially along the material conveying direction. The output end of the arranging conveyor mechanism is higher than the input end of the counting conveyor mechanism. A guiding mechanism is provided at the position where the material rolls from the arranging conveyor mechanism into the counting conveyor mechanism. The guiding mechanism includes a limiting component for ensuring that the material rolls in a single layer and guiding the posture of the rolling material, and a material blocking component for cooperating with the limiting component to ensure that the rolling material rolls into the counting conveyor mechanism one by one in an orderly manner. The counting conveyor mechanism includes a separating conveyor for carrying out the rolling material one by one in an orderly manner, and a counting device for counting the material carried out one by one.

[0007] In the aforementioned explosive cartridge limiting and counting device, preferably, the limiting component is located near or away from the material blocking component on the side of the material blocking component opposite to the arrangement and conveying mechanism. In the prior art, adding blades below the arc-shaped baffle can effectively prevent two cartridges from rolling down simultaneously. However, when dealing with cartridges of different specifications, replacing the blades is complex and time-consuming. If this causes malfunctions such as cartridge jamming, the maintenance and repair of the entire machine is also relatively cumbersome. With this preferred configuration, the material blocking component is movably located in front of the material rolling down, allowing for quick and flexible adjustment of the distance between the limiting component and the material blocking component according to the material size. This ensures that the material always rolls down to the counting and conveying mechanism one by one in an orderly manner, significantly shortening changeover time, simplifying the operation process, reducing maintenance difficulty, and greatly improving production efficiency and equipment reliability.

[0008] In the aforementioned explosive cartridge limiting and counting device, preferably, the limiting component includes a limiting cylinder assembly and a mounting frame. The limiting cylinder assembly is mounted on the mounting frame, and the mounting frame is mounted on the counting and conveying mechanism via a fixing member. The fixing member is located on both sides of the separating conveying member, and the fixing member has a first elongated groove along the conveying direction of the counting and conveying mechanism. The mounting frame is adjustablely positioned on the first elongated groove. With this configuration, the limiting cylinder assembly is securely mounted on the counting and conveying mechanism via the mounting frame. Furthermore, due to the fixing member design, adjusting the position of the limiting component becomes very convenient. Operators, guided by the first elongated groove, can quickly and accurately adjust the position of the limiting component according to the size and specifications of the explosive cartridge, greatly reducing adjustment time and improving production efficiency. In addition, the limiting component has a simple structure and is very easy to maintain.

[0009] In the aforementioned explosive cartridge limiting and counting device, preferably, the limiting cylinder assembly is mounted on the mounting frame and is movable in a direction perpendicular to the conveying surface of the counting conveying mechanism. By simply adjusting the position of the limiting cylinder assembly in the longitudinal (vertical) direction, suitable rolling space can be provided for materials of different sizes and specifications, forming a regular guide, and the distance between the upper end of the limiting cylinder assembly and the output end of the conveying mechanism can be adjusted to form a channel gap that allows only a single layer of explosive cartridges to pass through.

[0010] In the aforementioned explosive cartridge limiting and counting device, preferably, the mounting frame includes supports on both sides of the separating conveyor. The supports have a second elongated groove perpendicular to the conveying surface of the counting conveyor mechanism. The limiting cylinder assembly is adjustablely positioned on the second elongated groove via a fixing plate, with the limiting cylinder assembly located on the side of the fixing plate facing the conveying mechanism. Guided by the second elongated groove on the supports perpendicular to the conveying surface, the position of the limiting cylinder assembly can be quickly and accurately adjusted according to the material size.

[0011] In the aforementioned explosive cartridge limiting and counting device, preferably, the limiting cylinder assembly includes an upper limiting cylinder for allowing material to roll down in a single layer, a middle limiting cylinder for guiding the rolling material's posture, and a lower limiting cylinder for ensuring that the rolling material rolls down in an orderly manner. The axes of the upper, middle, and lower limiting cylinders are all perpendicular to the conveying direction. This single-layer, directional, and single-row triple limiting cylinder constraint allows material to pass through only in a single layer through the gap between the upper limiting cylinder and the output end of the conveying mechanism. This prevents material stacked on top from rolling off the upper layer, unlike traditional baffles. The middle limiting cylinder effectively guides the rolling posture of the material, correcting any deviation during the rolling process and ensuring that the axis of the explosive cartridge is perpendicular to the conveying direction. The lower limiting cylinder and the limiting assembly form a narrow-gap channel, ensuring that the material rolls down in an orderly manner to the counting conveying mechanism.

[0012] In the aforementioned explosive cartridge limiting and counting device, preferably, the upper limiting cylinder is located above the middle limiting cylinder near the side of the conveying mechanism, and the diameter of the lower limiting cylinder is smaller than the diameter of the middle limiting cylinder. By setting the cartridge in a stepped manner along the parabolic trajectory of the material, the cartridge can roll more smoothly into the counting conveying mechanism during the conveying process.

[0013] In the aforementioned explosive cartridge limiting and counting device, preferably, the separating conveyor includes a conveyor belt and conveyor baffles evenly spaced and vertically arranged on the conveyor belt. The baffle assembly includes a baffle plate vertically arranged on the conveying surface of the counting conveyor mechanism. The lower ends of the baffle plate and the limiting assembly are opposite to each other, and the baffle plate has a slot for the conveyor baffles to pass through. The conveyor baffles can accurately separate and carry out the sequentially rolling explosive cartridges, ensuring that the cartridges do not stick together or overlap during counting, significantly improving counting accuracy. The slots on the baffle plate for the conveyor baffles to pass through not only ensure the baffle plate's limiting function for the cartridges but also ensure that the conveyor baffles can run continuously without obstruction.

[0014] In the aforementioned explosive cartridge limiting and counting device, preferably, the counting device includes a first photoelectric sensor, which is disposed on the guide mechanism on the side opposite to the arrangement and conveying mechanism. The first photoelectric sensor can quickly capture the signal of the cartridge carried out by the conveying baffle, achieving instant counting and significantly improving counting efficiency. Furthermore, the first photoelectric sensor can move with the limiting component, adapting to different cartridge sizes and production needs. When the limiting component adjusts its position to fit the cartridge size, the sensor moves synchronously, always maintaining the optimal detection position without requiring readjustment, saving time.

[0015] In the aforementioned explosive cartridge limiting and counting device, preferably, the arranging and conveying mechanism includes an arranging belt, and a second photoelectric sensor is provided on one side of the arranging belt. The second photoelectric sensor can detect the quantity of incoming materials in real time. When the number of cartridges is too large, the speed of the arranging belt is slowed down, which can effectively prevent the cartridges from piling up during the conveying process and ensure that the cartridges can be arranged and conveyed in an orderly manner.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This invention, through the cooperation of the limiting component and the blocking component in the guiding mechanism, can regularly control the posture of the rolling medicine rolls, ensuring that they roll down one by one in a single layer with stable posture, thus accurately counting the medicine rolls. At the same time, the operation is very simple when changing production between different medicine roll specifications, with short changeover time. The simple and compact structure improves the overall stability of equipment operation, facilitates fault diagnosis and problem handling, and allows operators to quickly perform maintenance and adjustments. It significantly enhances the compatibility of the equipment to meet diverse production task requirements. Attached Figure Description

[0028] Example:

[0029] like Figures 1 to 3 As shown, the explosive cartridge limiting and counting device of this embodiment includes an arranging conveying mechanism 2 and a counting conveying mechanism 3 arranged sequentially along the material conveying direction. The output end of the arranging conveying mechanism 2 is higher than the input end of the counting conveying mechanism 3. A guiding mechanism 1 is provided at the position where the material rolls from the arranging conveying mechanism 2 into the counting conveying mechanism 3. The guiding mechanism 1 includes a limiting component 11 for ensuring that the material rolls down in a single layer and guiding the posture of the rolling material, and a blocking component 12 for cooperating with the limiting component 11 to make the rolling material roll down one by one in an orderly manner to the counting conveying mechanism 3. The counting conveying mechanism 3 includes a separating conveying component 31 for carrying out the rolling material one by one in an orderly manner, and a counting device for counting the material carried out one by one.

[0030] In this embodiment, the limiting component 11 can be located near or away from the material blocking component 12 on the side of the material blocking component 12 away from the conveying mechanism 2.

[0031] In this embodiment, as Figure 3 As shown, the limiting component 11 includes a limiting cylinder assembly 111 and a mounting frame. The limiting cylinder assembly 111 is mounted on the mounting frame, and the mounting frame is mounted on the counting conveying mechanism 3 via a fixing member 122. The fixing member 122 is located on both sides of the separating conveying member 31. The fixing member 122 has a first long groove 1221 along the conveying direction of the counting conveying mechanism 3, and the mounting frame is adjustablely positioned on the first long groove 1221.

[0032] In this embodiment, the limiting cylinder assembly 111 is mounted on the mounting frame and can move along the direction perpendicular to the conveying surface of the counting conveying mechanism 3.

[0033] In this embodiment, the mounting frame includes brackets 112 disposed on both sides of the separating conveyor 31. A second long groove 1121 perpendicular to the conveying surface of the counting conveyor 3 is provided on the brackets 112. A limiting cylinder assembly 111 is disposed on the second long groove 1121 through a fixing plate 113. The limiting cylinder assembly 111 is disposed on the side of the fixing plate 113 facing the arranging conveyor 2.

[0034] In this embodiment, the limiting cylinder assembly 111 includes an upper limiting cylinder 1111 for causing materials to roll down in a single layer, a middle limiting cylinder 1112 for guiding the posture of the rolling materials, and a lower limiting cylinder 1113 for causing the rolling materials to roll down one by one in an orderly manner. The axes of the upper limiting cylinder 1111, the middle limiting cylinder 1112, and the lower limiting cylinder 1113 are all perpendicular to the conveying direction.

[0035] In this embodiment, the upper limiting cylinder 1111 is located above the middle limiting cylinder 1112 near the side of the conveying mechanism 2, and the diameter of the lower limiting cylinder 1113 is smaller than the diameter of the middle limiting cylinder 1112.

[0036] In this embodiment, specifically, the upper limiting cylinder 1111 is located above the outlet end of the conveying mechanism 2, and its spacing ensures that a single layer of medicine rolls rolls down. The upper limiting cylinder 1111 is fixed above the middle limiting cylinder 1112, and the middle limiting cylinder 1112 and the lower limiting cylinder 1113 are fixed on the fixing plate 113.

[0037] In this embodiment, as Figure 1 As shown, the separating conveyor 31 includes a conveyor belt 311 and conveyor baffles 312 that are evenly spaced and vertically arranged on the conveyor belt 311. The baffle assembly 12 includes a baffle plate 121 that is vertically arranged on the conveying surface of the counting conveyor 3. The lower ends of the baffle plate 121 and the limiting assembly 11 are arranged opposite to each other. The baffle plate 121 has a slot 1211 for the conveyor baffles 312 to pass through.

[0038] In this embodiment, the baffle plate 121 is an L-shaped plate with its opening facing the limiting component 11. The L-shaped plate has vertically arranged triangular side plates on both sides. The baffle plate 121 is vertically mounted on the counting and conveying mechanism 3 by means of the fixing member 122. The baffle plate 121 with this structure can be stably mounted on the counting and conveying mechanism 3, accurately maintain a vertical state, and effectively prevent the baffle plate 121 from deforming and shifting.

[0039] In this embodiment, as Figure 2 As shown, the counting device includes a first photoelectric sensor 32, which is located on the guide mechanism 1 on the side opposite to the arrangement and conveying mechanism 2.

[0040] In this embodiment, the arranging conveyor mechanism 2 includes an arranging belt 21, and a second photoelectric sensor 22 is provided on one side of the arranging belt 21. Raised guardrails are provided on both sides of the arranging belt 21 to prevent the medicine rolls from falling.

[0041] In this embodiment, the specific steps include: first, adjusting the overall position of the limiting cylinder assembly 111 according to the diameter specifications of the drug rolls to ensure that, after adjustment, the distance between the upper limiting cylinder 1111 and the output end of the arranging belt 21 can effectively separate the double-layer drug rolls and ensure that the lower drug rolls reliably roll down in a single layer. Simultaneously, ensuring that the distance between the lower limiting cylinder 1113 and the L-shaped plate only allows a single drug roll to fall sequentially, then supplying the drug rolls from the upstream mechanism to the arranging belt 21 of the arranging conveyor mechanism 2, with the length direction of the drug rolls perpendicular to the conveying direction. When the pills are conveyed to the output end by the conveyor belt 21, they may form a double stack due to the continuous compression of the pills behind them. At this time, the upper limiting cylinder 1111 blocks the upper pills, allowing the lower pills to roll down smoothly. The rolling lower pills are calibrated by the middle limiting cylinder 1112. After the calibrated pills continue to fall, they fall accurately onto the lower L-shaped plate through the channel gap between the lower limiting cylinder 1113 and the L-shaped plate. Finally, they are carried out by the conveyor baffle 312, and the first photoelectric sensor 32 counts the pills carried out.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
