Description

Technical Field

[0001] The present application relates to the technical field of ammonium nitrate packaging, and in particular to an ammonium nitrate packaging device. Background Art

[0002] Ammonium nitrate is a common chemical used primarily in agriculture as a nitrogen fertilizer, but also in industry to produce explosives and other chemicals. It is hygroscopic and needs to be stored in a dry environment. Ammonium nitrate can decompose under certain conditions, releasing oxygen and nitrogen, and can explode if exposed to heat or fire in a confined space.

[0003] In the packaging process of ammonium nitrate, in order to make the subsequent transportation and storage of ammonium nitrate efficient, it is usually necessary to fill the ammonium nitrate into bags first, and then the conveying equipment transfers the bags to the grasping range of the palletizing robot. In order to make the bags accurately reach the operating range of the palletizing robot, a baffle that can prevent the bags from moving further is usually installed at the end of the conveying equipment.

[0004] Referring to the Chinese patent document with announcement number CN219097201U and announcement date May 30, 2023, named as a packaging auxiliary device for bagged powder, through the cooperation of the baffle, when the bagged powder stops on the packaging platform, the robotic arm gripper can directly grab the bagged powder and carry out subsequent palletizing and packaging work, which is easy to operate and has high work efficiency.

[0005] Referring to the above technical solution, when the material bags in the conveying state are blocked by the baffle, the ammonium nitrate inside the material bags may be squeezed to the side away from the baffle due to the blocking effect of the baffle. When the subsequent stacking work is carried out under this condition, since the center of gravity of the material bags will change with the position transfer of the ammonium nitrate, the ammonium nitrate inside the material bags will easily be irregularly dispersed again after the material bags are grabbed by the stacking robot, thereby affecting the stacking neatness of the material bags, and as the stacking height increases, the stacking frame may even collapse. Summary of the invention

[0006] In view of this, the present application provides an ammonium nitrate packaging device, which is mainly used to solve the problem that the ammonium nitrate inside the bag is easily irregularly dispersed during the subsequent grabbing process of the palletizing robot after the bag is blocked by the baffle.

[0007] In order to solve the above technical problems, the present application provides an ammonium nitrate packaging equipment, including a roller conveyor, a stacking robot and a stacking platform for stacking material bags; the end of the roller conveyor is slidably connected with a baffle through a gas strut, and a first cylinder is provided at the end of the roller conveyor, and the extension and contraction direction of the first cylinder is perpendicular to the conveying direction of the roller conveyor, and a fixed clamping plate is provided at the execution end of the first cylinder, and the fixed clamping plate is an L-shaped plate with a hollow horizontal part, and a movable clamping plate is hinged on the fixed clamping plate through a torsion spring, and an arc plate capable of abutting the movable clamping plate is provided on the roller conveyor; a linkage is provided between the fixed clamping plate and the baffle, which is used to move the baffle away from the material bag blocked by itself when the first cylinder is extended.

[0008] By adopting the above technical solution, a certain smoothing thrust and clamping force are applied to the bag by using the fixed clamping plate and the movable clamping plate, so that the ammonium nitrate can be distributed in the bag as evenly as possible, thereby improving the neatness of subsequent palletizing work.

[0009] Optionally, the linkage member includes a strip-shaped opening opened on the baffle, a linkage rod is fixedly connected to the fixed clamp, a push rod is provided on the linkage rod and can be inserted into the strip-shaped opening, and the push rod is inclined toward the direction close to the first cylinder with the conveying direction of the roller conveyor as the starting reference.

[0010] By adopting the above technical solution, with the help of the cooperation of the linkage rod, the push rod and the strip mouth, the baffle can be moved away from the bag when the first cylinder is extended, providing sufficient space for subsequent regularization work.

[0011] Optionally, a locking unit is provided on the roller conveyor for locking the position of the baffle or releasing the position lock of the baffle.

[0012] Optionally, the locking unit includes a spring pin arranged on the roller conveyor, a locking hole for inserting the spring pin is opened on the baffle, and a paddle is arranged on the linkage rod which can pull the spring pin out of the locking hole when the first cylinder contracts.

[0013] By adopting the above technical solution, with the cooperation of the spring pin and the locking hole, not only can the position of the baffle be locked to prevent the baffle from being accidentally reset during the regularization process, but also with the participation of the paddle, the resetting action of the baffle can have a certain hysteresis to prevent the ammonium nitrate in the bag from being squeezed again when the baffle is reset.

[0014] Optionally, a guide plate is provided on the roller conveyor to guide the conveying trajectory of the material bag during the conveying process.

[0015] By adopting the above technical solution, during the conveying process of the material bags, the material bags are guided to a position facing the baffle with the help of the cooperation of the guide plate, so that subsequent regularization work can be carried out normally.

[0016] Optionally, the guide plate is slidably connected to a roller conveyor, and a plurality of positioning bolts for pressing and limiting the guide plate are threadedly connected to the roller conveyor.

[0017] By adopting the above technical solution and a detachable connection method, personnel can freely adjust the position of the guide plate according to the size of the material bag, thereby meeting the use of material bags of different sizes.

[0018] Optionally, the executing end of the palletizing robot is provided with a second cylinder, and the executing end of the second cylinder is provided with a pressing plate.

[0019] By adopting the above technical solution, before the palletizing robot grabs the bag, the second cylinder drives the pressing plate to move downward to flatten the top of the bag, and the pressing plate always presses against the top of the bag during the grabbing process of the palletizing robot, further reducing the probability of ammonium nitrate inside the bag being dispersed after being grabbed.

[0020] Optionally, the conveying rollers at the starting section of the roller conveyor are square rollers.

[0021] By adopting the above technical solution, during the initial conveying process of the roller conveyor, the ammonium nitrate in the bag can vibrate slightly due to the extrusion generated by the edges of the square rollers, which is beneficial to the uniform distribution of the ammonium nitrate in the bag and reduces the burden of subsequent regularization work.

[0022] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By smoothing, pressing and clamping, the ammonium nitrate displaced by the baffle can be backfilled to a certain extent, so that the ammonium nitrate is distributed as evenly as possible inside the bag, reducing the probability of the ammonium nitrate inside the bag being dispersed after being grabbed.

[0024] 2. Use a movable baffle to block the material bags, which can not only keep the baffle away from the material bags during the backfilling and sorting process of ammonium nitrate, providing sufficient space for the backfilling and sorting work of ammonium nitrate, but also enable the baffle to be reset after the material bags are transferred by the palletizing robot to prevent the baffle from squeezing the ammonium nitrate in the material bags again.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 7 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0034] Reference Figure 1 This embodiment provides an ammonium nitrate packaging device, including a roller conveyor 1, a palletizing robot 2, a palletizing table 3 for stacking material bags, and a regular component arranged on the roller conveyor 1.

[0035] Among them, refer to Figure 2 , Figure 3 and Figure 4 The regular components include a baffle 4, a gas strut 41, a first cylinder 5, a fixed clamping plate 51, a movable clamping plate 52 and an arc plate 53. The baffle 4 is slidably connected to the end of the roller conveyor 1 through the gas strut 41, the first cylinder 5 is arranged at the end of the roller conveyor 1, and the extension direction of the first cylinder 5 is perpendicular to the conveying direction of the roller conveyor 1, the fixed clamping plate 51 is arranged at the execution end of the first cylinder 5, and the fixed clamping plate 51 is an L-shaped plate with a hollow horizontal part, the movable clamping plate 52 is hinged on the fixed clamping plate 51 through a torsion spring, and the arc plate 53 is arranged on the roller conveyor 1 and can abut against the movable clamping plate 52.

[0036] Among them, refer to Figure 2 , Figure 3 and Figure 4 A linkage member 6 is provided between the fixed clamping plate 51 and the baffle 4, and is used to move the baffle 4 away from the material bag blocked by itself when the first cylinder 5 is extended. The linkage member 6 includes a strip opening 61, a linkage rod 62 and a push rod 63. The strip opening 61 is opened on the baffle 4, the linkage rod 62 is fixedly connected to the fixed clamping plate 51, and the push rod 63 is arranged on the linkage rod 62 and can be inserted into the strip opening 61. The push rod 63 is inclined toward the direction close to the first cylinder 5 with the conveying direction of the roller conveyor 1 as the starting reference. When the first cylinder 5 is extended, the linkage rod 62 and the push rod 63 will move together with the fixed clamping plate 51 and be inserted into the strip opening 61. As the contact point between the push rod 63 and the strip opening 61 changes, the baffle 4 will be pulled away from the material bag by the push rod 63.

[0037] When carrying out the ammonium nitrate packaging work, when the roller conveyor 1 conveys the material bag to the grabbing range of the palletizing robot 2 and is blocked by the baffle 4, the roller conveyor 1 stops running, and the first cylinder 5 extends to push the fixed clamping plate 51 close to the material bag. During this process, the horizontal part of the fixed clamping plate 51 can initially smooth the ammonium nitrate at the top of the material bag to a certain extent.

[0038] As the first cylinder 5 extends, with the cooperation of the linkage 6, the baffle 4 will move away from the bag, so as to provide sufficient space for the subsequent regularization of the bag. At the same time, after the end of the movable clamping plate 52 away from its own hinge point abuts against the arc plate 53, the movable clamping plate 52 will rotate along the arc surface of the arc plate 53 with its own hinge point as the reference, until the movable clamping plate 52 is converted from a horizontal state to a vertical state, and the ammonium nitrate inside the bag will be dispersed inside the bag based on the conveying direction of the roller conveyor 1 under the extrusion of the vertical part of the fixed clamping plate 51 and the movable clamping plate 52, so that the ammonium nitrate displaced by the extrusion of the baffle 4 is backfilled to the side of the bag close to the baffle 4.

[0039] Then the first cylinder 5 contracts to reset the fixed clamping plate 51, and the movable clamping plate 52 returns to a horizontal state under the action of the torsion spring set at its own hinge point. During the resetting process of the fixed clamping plate 51, the hollow edge of the horizontal part of the fixed clamping plate 51 can smooth the ammonium nitrate on the top of the bag again, so that the ammonium nitrate is distributed as evenly as possible inside the bag. Finally, the palletizing robot 2 stacks the bags on the palletizing platform 3 to complete the palletizing work.

[0040] Reference Figure 2 and Figure 4The roller conveyor 1 is provided with a locking unit 7 for locking the position of the baffle 4 or releasing the position lock of the baffle 4. The locking unit 7 includes a spring pin 71, a locking hole 72 and a paddle 73. The spring pin 71 is provided on the roller conveyor 1. The locking hole 72 is provided on the baffle 4, and the locking hole 72 can be inserted into the spring pin 71. The paddle 73 is provided on the linkage rod 62. The paddle 73 can pull the spring pin 71 out of the locking hole 72 when the first cylinder 5 contracts.

[0041] When the baffle 4 is away from the material bag and the spring pin 71 is aligned with the locking hole 72, the spring pin 71 will be inserted into the locking hole 72 to lock the position of the baffle 4; when the first cylinder 5 contracts to drive the linkage rod 62 and the push rod 63 to completely reset and the stacking robot 2 transfers the material bag, the spring pin 71 will be pulled out from the locking hole 72 due to the action of the paddle 73. At this time, the baffle 4 will be reset due to the influence of the gas strut 41, so that the reset action of the baffle 4 has a certain hysteresis to prevent the ammonium nitrate in the material bag from being squeezed again when the baffle 4 is reset.

[0042] Reference Figure 2 and Figure 5 A guide plate 8 is provided on the roller conveyor 1 to guide the conveying trajectory of the bag during the conveying process.

[0043] During the conveying process of the material bags, the material bags are guided to a position facing the baffle 4 with the help of the cooperation of the guide plate 8, so that the subsequent regularization work can be carried out normally.

[0044] Reference Figure 2 and Figure 5 The guide plate 8 is slidably connected to the roller conveyor 1 , and a plurality of positioning bolts 81 for pressing and limiting the guide plate 8 are threadedly connected to the roller conveyor 1 .

[0045] The detachable connection method is adopted so that personnel can freely adjust the position of the guide plate 8 according to the size of the material bag, thereby meeting the use of material bags of different sizes.

[0046] Reference Figure 1 and Figure 6 The execution end of the palletizing robot 2 is provided with a second cylinder 9 , and the execution end of the second cylinder 9 is provided with a pressing plate 91 .

[0047] Before the palletizing robot 2 grabs the bag, the second cylinder 9 drives the pressing plate 91 to move downward to flatten the top of the bag, and the pressing plate 91 always presses against the top of the bag during the grabbing process of the palletizing robot 2, further reducing the probability of the ammonium nitrate inside the bag being dispersed after being grabbed.

[0048] Reference Figure 1 and Figure 7 The conveying rollers at the starting section of the roller conveyor 1 are square rollers.

[0049] During the initial conveying process of the roller conveyor 1, the ammonium nitrate in the bag can vibrate slightly due to the extrusion caused by the edges and corners of the square rollers, which is beneficial to the uniform distribution of the ammonium nitrate in the bag and reduces the burden of subsequent regularization work.

[0050] The implementation principle of an ammonium nitrate packaging device in the embodiment of the present application is:

[0051] When the roller conveyor 1 conveys the material bag to the grabbing range of the palletizing robot 2 and is blocked by the baffle 4, the roller conveyor 1 stops running, and the first cylinder 5 extends to push the fixed clamping plate 51 close to the material bag. During this process, the horizontal part of the fixed clamping plate 51 can initially smooth the ammonium nitrate on the top of the material bag to a certain extent.

[0052] As the first cylinder 5 extends, with the cooperation of the linkage 6, the baffle 4 will move away from the bag, so as to provide sufficient space for the subsequent regularization of the bag. At the same time, after the end of the movable clamping plate 52 away from its own hinge point abuts against the arc plate 53, the movable clamping plate 52 will rotate along the arc surface of the arc plate 53 with its own hinge point as the reference, until the movable clamping plate 52 is converted from a horizontal state to a vertical state, and the ammonium nitrate inside the bag will be dispersed inside the bag based on the conveying direction of the roller conveyor 1 under the extrusion of the vertical part of the fixed clamping plate 51 and the movable clamping plate 52, so that the ammonium nitrate displaced by the extrusion of the baffle 4 is backfilled to the side of the bag close to the baffle 4.

[0053] Then the first cylinder 5 contracts to reset the fixed clamping plate 51, and the movable clamping plate 52 returns to a horizontal state under the action of the torsion spring set at its own hinge point. During the resetting process of the fixed clamping plate 51, the hollow edge of the horizontal part of the fixed clamping plate 51 can smooth the ammonium nitrate on the top of the bag again, so that the ammonium nitrate is distributed as evenly as possible inside the bag. Finally, the palletizing robot 2 stacks the bags on the palletizing platform 3 to complete the palletizing work.

[0054] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
