Description

Technical Field

[0001] This invention relates to the field of civilian explosives production equipment technology, specifically to an emulsion explosive cartridge conveying and separating device. Background Technology

[0002] The production line for emulsion explosive cartridges is developing towards intelligent and unmanned operation. In the cartridge conveying process, the emulsion explosive cartridges (referred to as cartridges) are transported by a conveyor line through an AOI (Automated Optical Inspection) system. Defective cartridges are inspected by the AOI system and then removed by a subsequent rejection device, thereby improving the production quality of emulsion explosive cartridges.

[0003] However, currently, after the large cartridge handling device finishes and drops the cartridges onto the conveyor belt, adjacent cartridges will exhibit several different postures, including the following three situations:

[0004] 1. Two medicine rolls are connected end to end along the conveying direction, but not stacked; 2. Along the conveying direction, the tail of the front cartridge is stacked on top of the head of the rear cartridge; 3. The head of the later medicine roll is stacked on top of the tail of the previous medicine roll.

[0005] In all three of the above situations, it is impossible to set the spacing between adjacent emulsion explosive cartridges, which in turn affects the subsequent AOI visual inspection process (the cartridges are stacked vertically or connected front to back, causing obstruction and making it impossible to fully identify defects) and the rejection process (the stacked cartridges pull and entangle each other during rejection, affecting qualified cartridges). Therefore, before entering the AOI visual inspection system, it is necessary to arrange the emulsion explosive cartridges that are connected front to back or stacked to the spacing setting. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an emulsion explosive cartridge conveying and separating device.

[0007] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows: An emulsion explosive cartridge conveying and separating device includes a low-speed conveyor belt mechanism, a high-speed conveyor belt mechanism, and a stacking and separating mechanism. The low-speed conveyor belt mechanism includes a low-speed conveyor belt, and the high-speed conveyor belt mechanism includes a high-speed conveyor belt connected to the output end of the low-speed conveyor belt. The stacking and separating mechanism includes a flexible pressing and blocking member, which is disposed above the low-speed conveyor belt and near the connection between the low-speed and high-speed conveyor belts. The pressing and blocking height of the flexible pressing and blocking member relative to the low-speed conveyor belt is set to be greater than 1 times the outer diameter of the explosive cartridge and less than 2 times the outer diameter of the explosive cartridge.

[0008] Furthermore, the crimping blocking height of the flexible crimping blocking member relative to the low-speed conveyor belt is between 1.3 times and 1.7 times the outer diameter of the drug roll.

[0009] Furthermore, the flexible pressing blocking member includes a separating brush and a brush mounting sleeve, with one end of the separating brush mounted on the brush mounting sleeve and the other end extending radially outward along the brush mounting sleeve.

[0010] Furthermore, the stacking separation mechanism also includes a mounting shaft, and the brush mounting sleeve is fixedly connected to the mounting shaft in an axially adjustable manner. Limiting rings are provided on both sides of the brush mounting sleeve, and set screws are provided on the limiting rings. The ends of the set screws abut against the mounting shaft.

[0011] Furthermore, the brush mounting sleeve and the separate brush are integrally formed, and the brush mounting sleeve is keyed to the mounting shaft.

[0012] Furthermore, the flexible pressing blocking member is adjustable in vertical position relative to the low-speed conveyor belt, and multiple conveyor guards are provided on the low-speed conveyor belt along the width direction, forming a medicine roll conveying groove between the conveyor guards, and the distance between adjacent conveyor guards is adjustable.

[0013] Furthermore, the low-speed conveyor belt mechanism also includes a gantry spanning the low-speed conveyor belt, the gantry being provided with an elongated gantry hole extending along the width direction of the low-speed conveyor belt, and the conveyor guard plate being adjustablely connected to the elongated gantry hole.

[0014] Furthermore, the stacking separation mechanism also includes a first mounting base, a second mounting base, a vertical shaft, a vertical shaft positioning screw, a vertical shaft sleeve, a rotary drive component, and a bearing housing. The rotary drive component is fixedly connected to the vertical shaft and is drively connected to one end of the mounting shaft. The vertical shaft is vertically slidably connected to the vertical shaft sleeve and positioned by the vertical shaft positioning screw on the vertical shaft sleeve. The vertical shaft sleeve is mounted on the first mounting base. The other end of the mounting shaft mates with the bearing housing. The bearing housing is mounted on the second mounting base. The bearing housing has a vertically arranged elongated hole for mates with a connecting hole on the second mounting base.

[0015] Furthermore, the output end of the low-speed conveyor belt mechanism is equipped with a sensor for detecting drug roll blockage.

[0016] Furthermore, the direction of the linear velocity at the bottom of the brush mounting sleeve is the same as the conveying direction of the low-speed conveyor belt, and the linear velocity at the bottom of the brush mounting sleeve is greater than the conveying speed of the high-speed conveyor belt.

[0017] Compared with the prior art, the advantages of the present invention are as follows: This invention utilizes a low-speed conveyor belt mechanism, a high-speed conveyor belt mechanism, and a stacking and separating mechanism to effectively separate drug rolls in different postures after material handling, ensuring the accuracy of visual inspection and the reliability of rejecting NG drug rolls. Specifically, when two pill rolls are connected end-to-end but not stacked along the conveying direction, the speed difference between the high-speed and low-speed conveyor belts can quickly separate the pill rolls. When the tail of the front pill roll is stacked on the head of the rear pill roll along the conveying direction, the flexible pressing and blocking device relative to the low-speed conveyor belt is set to a pressing and blocking height greater than twice the outer diameter of the pill roll but less than twice the outer diameter of the pill roll. The flexible pressing and blocking device increases pressure on the front pill roll and provides force in the feeding direction. The increased pressure also increases the friction between the high-speed conveyor belt and the front pill roll, quickly separating the front pill rolls. When the head of the rear pill roll is stacked on the tail of the front pill roll, after the rear pill roll enters the high-speed conveyor belt, it will cause the pill rolls stacked at the tail to accelerate simultaneously, making it impossible to separate them. At this time, the upper flexible pressing and blocking device acts to block the rear pill roll. After the rear pill roll accelerates and detaches, the pill roll head falls onto the belt surface, and then the speed difference of the belts quickly separates the pill rolls.

[0020] To facilitate understanding of the present invention, the present invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of protection of the present invention is not limited to the following specific embodiments.

[0021] like Figure 1-7As shown, this embodiment discloses an emulsion explosive cartridge conveying and separating device, including a low-speed conveyor belt mechanism 1, a high-speed conveyor belt mechanism 2, and a stacking and separating mechanism 3. The high-speed conveyor belt mechanism 2 is equipped with an AOI vision inspection system 4. The low-speed conveyor belt mechanism 1 includes a low-speed conveyor belt 11 (the frames, drive rollers, driven rollers, and drive motors of both the low-speed conveyor belt mechanism 1 and the high-speed conveyor belt mechanism 2 are conventionally configured and will not be described in detail). The high-speed conveyor belt mechanism 2 includes a high-speed conveyor belt 21 connected to the output end of the low-speed conveyor belt 11. The conveying directions of the low-speed conveyor belt 11 and the high-speed conveyor belt 21 are consistent. A gap is provided between 21 to prevent interference, and their conveying planes are completely aligned. The stacking separation mechanism 3 includes a mounting shaft 32 and a flexible pressing stop. The flexible pressing stop is mounted on the mounting shaft 32 and is located above the low-speed conveyor belt 11 and near the connection between the low-speed conveyor belt 11 and the high-speed conveyor belt 21. Thus, when the tail of the front drug roll is stacked on the head of the rear drug roll along the conveying direction, the rear drug roll will enter the high-speed conveyor belt 21 first and be subjected to downward pressure by the flexible pressing stop, thus avoiding the problem of synchronous acceleration and inability to separate caused by both the front and rear drug rolls entering the high-speed conveyor belt 21. The crimping and blocking height H of the flexible crimping and blocking member relative to the low-speed conveyor belt 11 is set to be greater than 1 times the outer diameter D of the drug roll and less than 2 times the outer diameter D of the drug roll. Thus, the flexible crimping and blocking member can act on the stacked drug rolls. Specifically, the flexible crimping and blocking member can be a deformable, high-friction, and non-static ring structure, such as a relatively hard flexible sponge or brush. The crimping and blocking height H of the flexible crimping and blocking member relative to the low-speed conveyor belt 11 is between 1.3 times the outer diameter D of the drug roll and 1.7 times the outer diameter D of the drug roll. In this embodiment, the crimping and blocking height H is 1.5 times the outer diameter D of the drug roll. After experimentation, it can basically cover all drug roll stacking problems. When two pill rolls are connected end-to-end but not stacked along the conveying direction, the speed difference between the high-speed conveyor belt 21 and the low-speed conveyor belt 11 can quickly separate the pill rolls. When the tail of the front pill roll is stacked on the head of the rear pill roll along the conveying direction, the flexible pressing and blocking height H of the flexible pressing and blocking member relative to the low-speed conveyor belt 11 is set to be greater than 1 times the outer diameter D of the pill roll and less than 2 times the outer diameter D of the pill roll. The flexible pressing and blocking member increases the pressure on the front pill roll and provides a force in the feeding direction. The increased pressure also increases the friction between the high-speed conveyor belt 21 and the front pill roll, quickly separating the front pill rolls. When the head of the rear pill roll is stacked on the tail of the front pill roll, after the rear pill roll enters the high-speed conveyor belt 21, it will drive the pill rolls stacked at the tail to accelerate at the same time, causing them to not separate. At this time, the upper flexible pressing and blocking member acts to block the rear pill roll. After the rear pill roll accelerates and detaches, the head of the pill roll falls onto the belt surface, and then the speed difference of the belt quickly separates the pill rolls.This invention achieves effective separation of drug rolls in different postures after material handling by using a low-speed conveyor belt mechanism 1, a high-speed conveyor belt mechanism 2, and a stacking and separating mechanism 3, thereby ensuring the accuracy of visual inspection and the reliability of rejecting NG drug rolls (i.e., unqualified drug rolls identified by the AOI visual inspection system 4).

[0022] In this embodiment, the flexible pressing blocking component includes a separating brush 33 and a brush mounting sleeve 34. One end of the separating brush 33 is mounted on the brush mounting sleeve 34, and the other end extends radially outward along the brush mounting sleeve 34. The separating brush 33 is a relatively hard plastic structure, which can provide downward pressure on the medication roll and also act as a blocking agent. At the same time, the separating brush 33 has a certain degree of elasticity, which can adapt to different contact heights and avoid damage to the medication roll. The linear velocity direction of the bottom of the brush mounting sleeve 34 is the same as the conveying direction of the low-speed conveyor belt 11, and the linear velocity of the bottom of the brush mounting sleeve 34 is greater than the conveying speed of the high-speed conveyor belt 21, thereby improving the acceleration effect, reducing the friction distance and time, and reducing damage to the medication roll. Specifically, both the brush mounting sleeve 34 and the separating brush 33 are integrally molded and made of anti-static material, with a structure similar to a toothbrush. The brush mounting sleeve 34 is keyed to the mounting shaft 32, so it can move axially left and right, but is limited circumferentially by a key, thus rotating synchronously with the mounting shaft 32.

[0023] In this embodiment, to accommodate the separation of pill rolls with different outer diameters D, the brush mounting sleeve 34 is fixedly connected to the mounting shaft 32 in an axially adjustable manner. Limiting rings 35 are provided on both sides of the brush mounting sleeve 34, and set screws 36 are provided on the limiting rings 35. The ends of the set screws 36 abut against the mounting shaft 32 and are locked in place by friction. Simultaneously, the flexible pressing blocking member is vertically adjustable relative to the low-speed conveyor belt 11. Multiple conveyor guards 12 are arranged along the width direction on the low-speed conveyor belt 11, forming pill roll conveying grooves between them. The distance between adjacent conveyor guards 12 is adjustable.

[0024] Specifically, in order to achieve an adjustable distance between adjacent conveyor guard plates 12, the low-speed conveyor belt mechanism 1 also includes a gantry 13 spanning the low-speed conveyor belt 11. The gantry 13 is provided with a gantry elongated hole 14, which extends along the width direction of the low-speed conveyor belt 11. The conveyor guard plate 12 is adjustablely connected to the gantry elongated hole 14 by a bolt assembly.

[0025] In this embodiment, to achieve adjustable vertical position of the flexible pressing blocking member, the stacking separation mechanism 3 further includes a first mounting base 37, a second mounting base 38, a vertical shaft 39, a vertical shaft positioning screw 310, a vertical shaft sleeve 311, a rotary drive component 31, and a bearing seat 312. The rotary drive component 31 is a motor assembly with a reducer, and the rotary drive component 31 is driven by the mounting shaft 32. The first mounting base 37 and the second mounting base 38 are both connected to the frame of the low-speed conveyor belt mechanism 1. The rotary drive component 31 is fixedly connected to the vertical shaft 39 and is drivenly connected to one end of the mounting shaft 32. The vertical shaft 39 is vertically slidably connected to the vertical shaft sleeve 311 and positioned by the vertical shaft on the vertical shaft sleeve 311. Screw 310 is used for positioning, thereby enabling the up-and-down adjustment of one end of the mounting shaft 32. Vertical bushing 311 is installed on the first mounting base 37. The other end of the mounting shaft 32 is engaged with the bearing housing 312. The bearing housing 312 is installed on the second mounting base 38. The bearing housing 312 is vertically provided with a bearing housing elongated hole 314 for engaging with the connecting hole (threaded hole) on the second mounting base 38. That is, the connecting screw (a conventional fastener, not shown) is used to pass through the bearing housing elongated hole 314 to connect to the connecting hole on the second mounting base 38. The mounting shaft 32 passes through the second mounting base 38 and moves up and down synchronously with the bearing housing 312, thereby enabling the synchronous up-and-down adjustment of the other end of the mounting shaft 32.

[0026] In this embodiment, to prevent the medicine rolls from getting stuck, a sensor 15 for detecting the blockage of the medicine rolls is provided at the output end of the low-speed conveyor belt mechanism 1. An existing photoelectric sensor is used, which includes a transmitter (emitting modulated light) and a receiver (receiving light signals). The conveyor guard plate 12 is provided with a clearance hole for the sensor 15 to emit detection light. Under normal circumstances, the medicine rolls are conveyed back and forth at intervals. Due to the intermittent blocking of the detection light by the medicine rolls, the signal detected by the sensor 15 is intermittent. When the sensor 15 detects a continuous signal that is relatively long, it indicates that a blockage has occurred, and an alarm can be triggered.

[0027] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
