Description

Technical Field

[0001] This invention relates to the field of steel cylinder packaging technology, and more specifically, to an automated production line for steel cylinder packaging. Background Technology

[0002] As an important container, steel cylinders play a crucial role in industrial production and logistics transportation. They are mainly used for storing, transporting, and using high and low pressure liquefied gases, such as high-purity gases (argon, nitrogen, oxygen, hydrogen, helium, etc.), standard gases (containing trace amounts of carbon monoxide, methane, nitric oxide, nitrogen dioxide, etc.), and special gases (such as chlorine trifluoride). Steel cylinders mainly consist of a cylinder body and a handle. After production, steel cylinders need to be packaged to ensure their safety and stability during transportation and storage. Packaging usually involves placing the steel cylinders individually in a packaging box. After the cylinders are placed in the packaging box, foam molds are usually used to limit and fix the cylinders, reducing shaking caused by gaps.

[0003] In existing technologies, cylinder loading involves manually placing the cylinders onto a conveyor line. However, manual loading cannot guarantee that the opening direction of the cylinder handles is consistent. Furthermore, during the feeding process, factors such as contact between the cylinder and the upper limit baffle of the conveyor line, or mechanical vibration of the conveyor line, can cause the cylinders to deflect during transport, resulting in inconsistent cylinder handle opening directions. If the cylinder handle opening directions are not adjusted, cylinders with inconsistent handle opening directions will cause the foam mold's slots to not align with the cylinder handle opening positions after being placed in the packaging box. This prevents the foam mold from being fully inserted into the packaging box to limit and fix the cylinder. Manual correction leads to low processing accuracy, failing to meet the needs of high-efficiency production and severely impacting production efficiency. Moreover, prolonged manual operation can easily lead to fatigue and errors, further affecting production efficiency and potentially causing safety accidents.

[0004] This invention provides an automated production line for steel cylinder packaging, aiming to solve the problem that it is impossible to ensure that the steel cylinders are oriented in the same direction when they are packed into the packaging box, which makes it impossible for the foam mold to be fully placed into the packaging box to limit and fix the steel cylinders, thus affecting production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automated production line for steel cylinder packaging, in order to solve the problem mentioned in the background art that it is impossible to ensure that the steel cylinders are oriented in the same direction when packed into the packaging box, so that the foam mold cannot be completely placed into the packaging box to limit and fix the steel cylinders, thus affecting production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic production line for steel cylinder packaging, comprising a first conveyor line and a second conveyor line, wherein a case opener, a case packer, a foam mold placement machine, and a case sealer are sequentially arranged along the conveying direction of the first conveyor line, and further comprising:

[0007] A correction mechanism, mounted on the case packer, is used to correct the angle of the cylinders during the process of placing them into the packaging box. It includes multiple clamping components for holding the cylinder handles. When clamped, the inner sides of these clamping components can form a circle to hold the cylinder handles. Each clamping component has an adjustment groove on its inner side, and an adjustment block is rotatably connected inside each adjustment groove. Each adjustment block has several evenly distributed telescopic grooves on its inner side, and a telescopic block is slidably connected inside each telescopic groove.

[0008] Preferably, each of the adjusting blocks has a first elastic element connected between one end of the corresponding telescopic groove and the corresponding telescopic groove, a first conductive contact is fixedly embedded inside the telescopic groove, and a second conductive contact is fixedly embedded on the side of each telescopic block near the corresponding first conductive contact. When the first conductive contact and the second conductive contact come into contact, an electrical signal can be generated.

[0009] Preferably, each of the clamping members has a first driving groove on its inner side, each first driving groove is connected to the corresponding adjustment groove, each first driving groove has a first driving block slidably connected inside, each first driving block has a second elastic element connected between one end inside the corresponding first driving groove and the corresponding first driving groove, each first driving block has a guide post fixedly connected to the side near the corresponding adjustment groove, each adjustment block has a guide groove on the side near the corresponding first driving groove, and each guide post is slidably connected in the corresponding guide groove.

[0010] Preferably, each of the first driving blocks has a second driving groove on the side away from the corresponding second elastic member, and a second driving block is slidably connected inside each of the second driving grooves. A third elastic member is connected between one end of each second driving block located inside the corresponding second driving groove and the corresponding second driving groove. The elastic coefficient of the third elastic member is greater than that of the second elastic member.

[0011] Preferably, the first conveyor line, the second conveyor line, the case opener, the case packer, the foam mold placement machine, the case sealer, and the correction mechanism are all electrically connected to the controller, and the controller can receive the electrical signal generated when the first conductive contact and the second conductive contact come into contact.

[0012] Preferably, the second conveyor line is used to convey steel cylinders, and both the first and second conveyor lines are equipped with limit baffles. The case packer is used to move the steel cylinders on the second conveyor line into the packaging boxes on the first conveyor line.

[0013] Preferably, the packing machine includes a support frame, a transverse component is provided on the support frame, a lifting component is provided on the transverse component, a rotating device is provided on the lifting component, and a clamping device is provided on the rotating device. The plurality of clamping components are respectively fixedly connected to the plurality of corresponding clamping arms on the clamping device.

[0014] Preferably, the box opener is used for feeding, opening, and bottom sealing of packaging boxes, and then conveying the bottom-sealed packaging boxes to the first conveyor line.

[0015] Preferably, the foam mold placement machine includes a feeding device and a transferring device. The feeding device is used to feed the foam mold, and the transferring device is used to move the foam mold on the feeding device into a packaging box on the first conveyor line.

[0016] Preferably, the box sealing machine is used to seal the top of the packaging box on the first conveyor line.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention, through the setting of a correction mechanism, causes the outer wall of the cylinder handle to contact several telescopic blocks, which in turn squeeze the blocks into corresponding telescopic grooves. This causes the corresponding second conductive contact to contact the corresponding first conductive contact, generating an electrical signal. The controller can determine the cylinder angle based on the electrical signal and, during the movement process, control the rotating device to drive the clamping device and the correction mechanism to rotate based on the cylinder angle determined by the electrical signal. This corrects the cylinder angle, ensuring that the angle of the cylinder remains uniform after it is placed in the packaging box. This allows the subsequent foam mold to be smoothly placed into the packaging box without manual adjustment, thereby improving production efficiency and avoiding safety accidents.

[0019] 2. Through the arrangement of the first driving block, guide post, and guide groove, the present invention ensures that when multiple clamping components clamp the cylinder, the cylinder handle will press against the second driving block, causing the first driving block to move. During the movement, the guide post and guide groove will cooperate to drive the adjusting block and several telescopic blocks to rotate, so that the telescopic blocks contact the edge of the cylinder handle opening during rotation. This ensures that the number of telescopic blocks at the cylinder handle opening is consistent, avoiding affecting the judgment of the cylinder angle and thus improving the subsequent correction accuracy.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] refer to Figures 1 to 10 An automatic production line for steel cylinder packaging according to an embodiment of the present invention includes a first conveyor line 1 and a second conveyor line 2. A case opener 3, a case packer 4, a foam mold placement machine 5 and a case sealer 6 are arranged sequentially along the conveying direction of the first conveyor line 1.

[0034] refer to Figure 1 The second conveyor line 2 is used to transport steel cylinders. Both the first conveyor line 1 and the second conveyor line 2 are equipped with limit baffles 11. Both the first conveyor line 1 and the second conveyor line 2 are equipped with limit devices and sensors for detecting the position of the packaging box and the steel cylinder. These sensors are used to limit the position of the box or the steel cylinder after it reaches the designated position. The case opener 3 is used for loading, opening and sealing the bottom of the packaging box, and then transporting the bottom-sealed packaging box to the first conveyor line 1. The case opener 3 is existing technology and will not be described in detail here.

[0035] refer to Figure 3 The case packer 4 is used to move the steel cylinders on the second conveyor line 2 into the packaging boxes on the first conveyor line 1. The case packer 4 includes a support frame 41, a transverse component 42 is provided on the support frame 41, and a lifting component 43 is provided on the transverse component 42. The transverse component 42 and the lifting component 43 can be driven by a screw module or a cylinder. The lifting component 43 is provided with a rotating device 44, which can be a motor or a rotary cylinder. The rotating device 44 is provided with a clamping device 45, which can be a three-jaw clamping cylinder.

[0036] refer to Figure 1 The foam mold placement machine 5 includes a feeding device 51 and a transferring device 52. Both the feeding device 51 and the transferring device 52 are existing technologies and will not be described in detail here. The feeding device 51 is used to feed the foam mold, and the transferring device 52 is used to move the foam mold on the feeding device 51 to the packaging box on the first conveyor line 1. The box sealing machine 6 is used to seal the top of the packaging box on the first conveyor line 1. The box sealing machine 6 is existing technology and will not be described in detail here.

[0037] refer to Figures 4 to 8 It also includes a correction mechanism 7, which is installed on the packing machine 4 and is used to correct the angle of the cylinder during the process of putting the cylinder into the packaging box. The correction mechanism 7 includes multiple clamping parts 71 for clamping the cylinder handle. When the multiple clamping parts 71 are in the clamping state, their inner sides can form a circle to clamp the cylinder handle. The multiple clamping parts 71 are fixedly connected to the corresponding multiple clamping arms on the clamping device 45. Each clamping part 71 has an adjustment groove 72 on its inner side. Each adjustment groove 72 has an adjustment block 73 rotatably connected inside. Each adjustment block 73 has several evenly distributed telescopic grooves 74 on its inner side. Each telescopic groove 74 has a telescopic block 75 slidably connected inside.

[0038] refer to Figure 7 and Figure 8 Each adjusting block 73 has a first elastic element 76 connected to one end of the corresponding telescopic groove 74. Each telescopic groove 74 has a first conductive contact 77 fixedly embedded inside. Each telescopic block 75 has a second conductive contact 78 fixedly embedded on the side close to the corresponding first conductive contact 77. When the first conductive contact 77 and the second conductive contact 78 come into contact, an electrical signal can be generated.

[0039] The first conveyor line 1, the second conveyor line 2, the box opener 3, the box packer 4, the foam mold placement machine 5, the box sealing machine 6, and the correction mechanism 7 are all electrically connected to the controller. The controller can receive the electrical signal generated when the first conductive contact 77 and the second conductive contact 78 come into contact.

[0040] In actual production, the folded packaging box is first placed into the feeding position of the case opener 3. Then, the case opener 3 uses a vacuum suction cup inside to pick up the packaging box and applies a backward pulling force to unfold it into a three-dimensional box. During the conveying process, the bottom of the packaging box is sealed and then conveyed to the first conveyor line 1. The sealed packaging box is then conveyed to the case packer 4 via the first conveyor line 1.

[0041] Simultaneously, the cylinders are manually placed on the second conveyor line 2, which then transports them to the case packing machine 4. Once the case and cylinders reach the case packing machine 4, sensors detect them. When the controller receives the sensor's detection signal, it controls the limit device to limit the case and cylinders, and controls the transverse component 42 to adjust the position of the clamping device 45 so that it aligns with the position of the cylinders on the second conveyor line 2. Then, the lifting component 43 drives the rotating device 44, the clamping device 45, and the correction mechanism 7 to move downwards. After the lifting component 43 moves the clamping device 45 and the correction mechanism 7 to their limit positions, the clamping device 45 is activated. The clamping device 45 drives multiple clamping parts 71 to move synchronously toward the cylinders to clamp them.

[0042] During the clamping process of the gas cylinder, the multiple clamping members 71 will drive the corresponding telescopic blocks 75 to move towards the gas cylinder. The telescopic blocks 75 that are in contact with the outer wall of the gas cylinder handle will be squeezed into the corresponding telescopic grooves 74 and compress the first elastic member 76. The telescopic blocks 75 located at the opening of the gas cylinder handle will remain in the extended state. The telescopic blocks 75 that are squeezed into the corresponding telescopic grooves 74 will drive the corresponding second conductive contact 78 to contact the corresponding first conductive contact 77 and generate an electrical signal. At this time, the controller can determine the angle of the gas cylinder based on the electrical signal.

[0043] After the clamping device 45 drives the clamping component 71 to clamp the cylinder, the controller controls the lifting component 43 to drive the rotating device 44, the clamping device 45, the correction mechanism 7, and the cylinder to move upward. During the movement, the controller controls the rotating device 44 to drive the clamping device 45 and the correction mechanism 7 to rotate according to the cylinder angle determined by the electrical signal, so as to correct the cylinder angle and keep the angle of the cylinder uniform after it is placed in the packaging box.

[0044] After the correction is completed, the controller controls the lateral movement component 42, the lifting component 43 and the clamping device 45 to place the steel cylinder into the corresponding packaging box. Then, it controls the corresponding limit device to descend and release the packaging box containing the steel cylinder. The packaging box containing the steel cylinder is transported to the corresponding position of the foam mold placement machine 5 through the first conveyor line 1. When the sensor at the corresponding position detects the packaging box, the controller controls the limit device at the corresponding position to limit the packaging box containing the steel cylinder, so that the packaging box containing the steel cylinder stops at the position of the foam mold placement machine 5. At this time, the controller controls the material transfer device 52 to put the foam mold on the feeding device 51 into the packaging box containing the steel cylinder, and limit and support the steel cylinder.

[0045] After the foam mold is placed, the controller controls the corresponding limit device to descend, releasing the packaging box containing the steel cylinder and foam mold. Then, the packaging box containing the steel cylinder and foam mold is transported to the sealing machine 6 through the first conveyor line 1 to complete the sealing.

[0046] It should be noted that during the process of transferring the cylinders by the packing machine 4, if a power outage or misoperation occurs and affects the clamping effect of the clamping device 45 and the correction mechanism 7, the cylinder may slip from the corresponding clamping parts 71. When the cylinder slips, the positions of the multiple handle slots on the handle correspond to the positions of several telescopic blocks 75. The telescopic blocks 75 located in the telescopic groove 74 will extend under the pushing force of the first elastic element 76. At this time, the several extended telescopic blocks 75 will be supported in the multiple handle slots of the cylinder handle, which can prevent the cylinder from falling, avoid damage to the cylinder and safety accidents caused by falling, thereby improving safety.

[0047] The purpose of correcting the cylinder angle by rotating device 44 during movement, rather than by correcting the cylinder angle on the conveyor line or within the packaging line, is that correcting the cylinder angle on the conveyor line or within the packaging box would cause contact friction between the conveyor line, the limit baffle 11, and the packaging box, requiring greater driving force to correct the angle, increasing production costs, and also causing wear and tear on the conveyor line, packaging box, and cylinder, affecting the service life of the conveyor line and causing damage to the packaging box. If the wear is severe, the protective layer of the cylinder may fall off, easily corroding the cylinder and shortening its service life.

[0048] In summary, by setting up the correction mechanism 7, after the outer wall of the cylinder handle comes into contact with several telescopic blocks 75, it will squeeze the telescopic blocks 75 into the corresponding telescopic grooves 74. This will cause the corresponding second conductive contact 78 to come into contact with the corresponding first conductive contact 77 and generate an electrical signal. The controller can determine the cylinder angle based on the electrical signal, and during the movement process, it can control the rotating device 44 to drive the clamping device 45 and the correction mechanism 7 to rotate based on the cylinder angle determined by the electrical signal, thereby correcting the cylinder angle. This ensures that the angle of the cylinder remains uniform after it is placed in the packaging box, allowing the subsequent foam mold to be smoothly placed into the packaging box without manual adjustment, thus improving production efficiency and avoiding safety accidents.

[0049] Example 2

[0050] In actual production, since the angle of the cylinder on the second conveyor line 2 cannot be kept uniform, the correction mechanism 7 cannot guarantee that the number of telescopic blocks 75 located at the opening of the cylinder handle is consistent each time when clamping and limiting the cylinder. This affects the cylinder angle judgment and the subsequent correction accuracy. Therefore, this embodiment improves the device described in the above embodiment.

[0051] refer to Figures 6 to 10 Each clamping member 71 has a first driving groove 79 on its inner side. Each first driving groove 79 is connected to a corresponding adjustment groove 72. A first driving block 710 is slidably connected inside each first driving groove 79. A second elastic member 711 is connected between one end of each first driving block 710 located inside the corresponding first driving groove 79 and the corresponding first driving groove 79. A guide post 712 is fixedly connected to the side of each first driving block 710 near the corresponding adjustment groove 72. A guide groove 713 is opened on the side of each adjustment block 73 near the corresponding first driving groove 79. Each guide post 712 is slidably connected in the corresponding guide groove 713.

[0052] refer to Figure 9 and Figure 10 Each first driving block 710 has a second driving groove 714 on the side away from the corresponding second elastic member 711. A second driving block 715 is slidably connected inside each second driving groove 714. A third elastic member 716 is connected between one end of each second driving block 715 inside the corresponding second driving groove 714 and the corresponding second driving groove 714. The elastic coefficient of the third elastic member 716 is greater than the elastic coefficient of the second elastic member 711.

[0053] In actual production, when multiple clamping components 71 clamp the gas cylinder and the cylinder handle pushes several telescopic blocks 75 into the corresponding telescopic grooves 74, the cylinder handle will press the second driving block 715 in contact with it. Since the elastic coefficient of the third elastic element 716 is greater than that of the second elastic element 711, after the second driving block 715 is pressed, it will push the first driving block 710 to move in the corresponding first driving groove 79 through the third elastic element 716, and compress the corresponding second elastic element 711. During the movement, the first driving block 710 will be adjusted through the cooperation of the guide post 712 and the guide groove 713. The block 73 rotates within the corresponding adjustment groove 72. During the rotation of the adjustment block 73, it will drive several corresponding telescopic blocks 75 to rotate. The telescopic blocks 75 located at the edge of the cylinder handle opening will contact the edge of the cylinder handle opening during the rotation. This process is repeated so that the adjustment block 73 drives the telescopic blocks 75 to rotate during the clamping process of the clamping member 71, so that the telescopic blocks 75 located at the edge of the cylinder handle opening can uniformly contact the edge of the cylinder handle opening. This ensures that the number of telescopic blocks 75 located at the cylinder handle opening is consistent, avoiding affecting the cylinder angle judgment, thereby improving the subsequent correction accuracy.

[0054] After the telescopic block 75 contacts the edge of the cylinder handle opening, the adjusting block 73 can no longer rotate, so that the first driving block 710 can no longer slide in the first driving groove 79. If the cylinder handle continues to squeeze the second driving block 715, the second driving block 715 will compress the third elastic member 716 and slide in the corresponding second driving groove 714, which will not affect the clamping member 71's clamping of the cylinder.

[0055] It should be noted that when one of the second driving blocks 715 is located inside the opening of the cylinder handle, the second driving block 715 cannot be squeezed by the cylinder handle and cannot drive the corresponding adjusting block 73 to rotate. Since the inner sides of the multiple clamping members 71 can form a circle to clamp the cylinder handle when they are in the clamping state, the other adjusting blocks 73 can contact the adjusting block 73 corresponding to the second driving block 715 when rotating. During the clamping process of the multiple clamping members 71 on the cylinder, the other adjusting blocks 73 can push the adjusting block 73 corresponding to the second driving block 715 to rotate synchronously. During the rotation, the adjusting block 73 corresponding to the second driving block 715 can drive the corresponding first driving block 710 to move through the cooperation of the guide post 712 and the guide groove 713, and compress the corresponding second elastic member 711.

[0056] In summary, through the arrangement of the first driving block 710, guide post 712, and guide groove 713, when multiple clamping parts 71 clamp the cylinder, the cylinder handle will press against the second driving block 715, causing the first driving block 710 to move. During the movement, the guide post 712 and guide groove 713 will cooperate to drive the adjusting block 73 and several telescopic blocks 75 to rotate, so that the telescopic blocks 75 contact the edge of the cylinder handle opening during rotation. This ensures that the number of telescopic blocks 75 located at the cylinder handle opening is consistent, avoiding affecting the cylinder angle judgment and thus improving the subsequent correction accuracy.

[0057] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
