Description

Technical Field

[0001] The present invention belongs to the technical field of accessory packaging, and particularly relates to a mechanical spare part packaging device with high efficiency. Background Art

[0002] Mechanical spare parts are key components in industrial manufacturing, referring to industrial products that have been processed and constitute the core units of final products, such as gears, bearings, instruments, etc. Their performance directly affects the operation efficiency and quality of equipment, and they are widely used in fields such as automobiles, electronics, and mechanical manufacturing.

[0003] There is a mechanical spare part packaging device with the publication number of CN222432707U, including a base. At the top of the left side of the base, there is a conveying device. On both sides of the top of the base, there are connecting rods fixedly connected. Inside the connecting rods, there are guide plates fixedly connected, and the guide plates are all located on the top of the base. Among them, when spare parts are conveyed by the conveying device to the inside of the guide plates, they slide into the inside of the cylinder through the side guide plates and guide rollers, and slide onto the surface of the spiral blade. At the same time, the motor is started to make the rotating rod rotate. The rotation of the rotating rod drives the rotation of the spiral blade, and the rotation of the spiral blade conveys the spare parts at the top to the bottom and drops them into the inside of the packing box.

[0004] In the above solution, the spare parts are conveyed through the setting of the spiral blade. On the one hand, although the spare parts slide down on the spiral blade, which slows down the falling speed of the spare parts, when the spare parts slide down along the spiral blade, they are still prone to bump with the bottom of the carton, resulting in damage to the carton or the corners of the spare parts being bumped. And due to the small gap between the spiral blades, the size of the transported spare parts is greatly restricted. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a mechanical spare part packaging device with high efficiency, aiming to solve the problem that the existing mechanical spare part packaging device is prone to damage the box body or spare parts when packing the spare parts.

[0006] The present invention is implemented as follows. A mechanical spare part packaging device with high efficiency includes a support base. At the top of the support base, there is a rotating shaft rotatably connected. In the support base, there is a first motor that drives the rotation of the rotating shaft. The rotating shaft is fixedly connected with a rotating table. On one side of the rotating table, there is a belt conveying device for conveying spare parts. The rotating table is horizontally slidably connected with a plurality of placing seats. The placing seats are all connected with adjusting components.

[0009] Further technical solution, the positioning assembly includes a rotating sleeve, a fixed seat and a magnetic block;

[0010] The rotating sleeve is rotatably connected to the outer wall of the protective cover. A plurality of fixed seats are fixedly connected to the rotating sleeve. Magnetic blocks are slidably connected in the fixed seats. A limiting groove is arranged on the placing seat, and a plurality of limiting plates are arranged around the limiting groove. When the electric lifting seat contracts, all the magnetic blocks correspond to the limiting plates one by one.

[0011] Further technical solution, the buffer mechanism includes a first rotating seat, a rotating rod, a rubber sleeve, a buffer air bag and a first air duct;

[0012] A plurality of first rotating seats are arranged at the bottom of the protective cover. The first rotating seats are rotatably connected with rotating rods through elastic torsion springs. Rubber sleeves are rotatably connected to the outside of the rotating rods. Buffer air bags are arranged at the ends of the rotating rods close to the center of the protective cover. The buffer air bags are communicated with a first air duct, and the first air duct penetrates through the rotating rod and the side wall of the protective cover and is communicated with the air outlet pipe of the air pump.

[0013] Further technical solution, the limiting mechanism includes a second rotating seat, a connecting ring sleeve, a rubber ring and a third motor;

[0014] A second rotating seat is arranged at a position close to the top of the protective cover. The second rotating seat is fixedly connected with a third motor. The output shaft of the third motor is rotatably connected with a connecting ring sleeve. An electromagnetic ring connected with a micro battery is arranged in the connecting ring sleeve. The connecting ring sleeve is connected with a rubber ring.

[0015] Further technical solution, the protective mechanism includes a third rotating seat, a protective plate, a spring and a protective air bag;

[0016] A plurality of third rotating seats are fixedly connected to the inner wall of the protective sleeve. Each third rotating seat is rotatably connected to a protective plate. All the protective plates are inclined in the same direction. A spring is connected between the third rotating seat and the protective plate. A protective airbag is arranged in the protective plate. A plurality of strip-shaped grooves for accommodating the protective airbag are formed on the surface of the protective plate. The protective airbag is communicated with the air outlet pipe of the air pump through a second air guide pipe.

[0017] In a further technical solution, a plurality of guide grooves are formed on the surface of the rotating table in the diameter direction. The base of each placing seat is correspondingly slidably connected in one of the guide grooves. The adjusting assembly includes a second motor and a threaded rod. A second motor is fixedly arranged on one side of each guide groove. The output shaft of the second motor is fixedly connected to the threaded rod. The threaded rods are all threadedly connected to the base of the placing seat.

[0018] In a further technical solution, an annular airbag is connected to the outer wall of the protective sleeve. The annular airbag is communicated with the air pump through a third air guide pipe.

[0019] In a further technical solution, the control system includes:

[0020] A monitoring module, which includes a pressure sensor and a torque sensor. Pressure sensors are arranged at the joints of the buffer airbag and the rotating rod. Torque sensors are arranged at the joints of the protective plate and the spring;

[0021] A processing module, which is used to judge the pressure signal of the pressure sensor and the torque signal of the torque sensor, and form a judgment message;

[0022] A control module, which controls the first motor, the adjusting assembly, the driving assembly, the limiting mechanism and the air pump according to the judgment message of the processing module.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. When the spare parts fall into the middle of the protective sleeve, the pressure sensor under the buffer airbag emits a signal first. After receiving the signal, the processing module immediately controls the driving assembly to drive the protective sleeve to rotate. The protective sleeve buffers and unloads the force of the spare parts through the protection mechanism, and according to the pressure magnitude of the pressure sensor, the control system controls the air pump to increase the volume of air pressure in the protective airbag, so as to enhance the protection effect on the spare parts;

[0025] 2. When the spare parts fall to the side wall of the protective cover, the torque sensor is pre-pressed and sends a signal, while the pressure sensor does not send a signal. After receiving the signal, the processing module immediately controls the driving component to drive the protective cover to rotate. The protective cover buffers and unloads the spare parts through the protective mechanism, and the processing module controls the limit mechanism to flip into the protective cover, thereby adsorbing and fixing the spare parts. At this time, the rubber cover, rubber ring and protective airbag jointly provide elastic protection for the spare parts;

[0026] 3. When the spare parts fall to the side wall of the protective cover, the processing module can determine the landing point of the spare parts in the protective cover according to the position of the protective plate where the torque sensor is located, and adjust the rotation angle of the turntable gap by adjusting the rotation angle of each intermittent rotation of the No. 1 motor, and adjust the position of the placement seat on the turntable by adjusting the component, and finally change the position of the carton on the lower side of the belt conveyor when the spare parts fall, so that the spare parts can always fall into the middle of the carton when they fall, avoiding the spare parts from falling outside the carton or the spare parts from continuously colliding with the side wall of the carton;

[0027] 4. In the present invention, through the cooperation between the protective cover and various buffer mechanisms and protective mechanisms, not only can the spare parts be buffered and protected while they fall, but the carton can also be effectively stabilized when the spare parts fall. Furthermore, compared with the comparative documents, the cooperation between the various buffer mechanisms and protective mechanisms of the protective cover can minimize the occupation of the internal space of the carton. When the electric lifting seat is extended to drive the protective cover to detach from the carton, at this time, each buffer mechanism is gradually reset to a cone shape driven by the elastic torsion spring. Through the various buffer mechanisms, the spare parts can also be guided and protected, so that the spare parts can be stably maintained in the center of the carton.

Detailed implementation manners

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0039] As Figures 1-8 shown, a highly efficient mechanical parts packaging device provided by an embodiment of the present invention includes a support base 1. A rotating shaft 10 is rotatably connected to the top of the support base 1. A first motor for driving the rotating shaft 10 to rotate is provided in the support base 1. The rotating shaft 10 is fixedly connected to a rotating table 2. A belt conveyor for conveying parts is provided on one side of the rotating table 2. A plurality of placing seats 11 are horizontally slidably connected to the rotating table 2. Each placing seat 11 is connected to an adjustment component 3. The adjustment component 3 can drive the placing seat 11 to move along the radial direction of the rotating table 2. An electric lifting seat 14 is provided on the upper end surface of the placing seat 11. The telescopic end of the electric lifting seat 14 is fixedly connected to a fixing plate 15. A protection sleeve 16 is slidably clamped to the fixing plate 15. A driving component 4 for driving the protection sleeve 16 to rotate is provided on the fixing plate 15. The driving component 4 is composed of a fourth motor and a gear. The fourth motor drives the gear to rotate. The gear meshes with the gear ring outside the protection sleeve 16, and the rotation of the gear drives the protection sleeve 16 to rotate.

[0040] A plurality of buffer mechanisms 6 are rotatably connected to the bottom of the protective sleeve 16 through elastic torsion springs. The buffer mechanisms 6 are inclined in the natural state. The buffer mechanisms 6 can buffer the spare parts and guide the spare parts towards the side wall of the protective sleeve 16. A limiting mechanism 7 is rotatably connected to the top of the protective sleeve 16. The limiting mechanism 7 can vertically limit the spare parts in the protective sleeve 16. A plurality of protective mechanisms 8 for protecting the spare parts are rotatably connected to the inner wall of the protective sleeve 16. The protective sleeve 16 is connected with an air pump 17. The air pump 17 is communicated with both the buffer mechanism 6 and the protective mechanism 8. A positioning assembly 5 for positioning the cardboard box is arranged outside the protective sleeve 16.

[0041] A control system, which can monitor the landing point of the spare parts in the protective sleeve 16, and the control system can control the first motor, the adjustment assembly 3, the drive assembly 4, the limiting mechanism 7 and the air pump 17 according to the landing point of the spare parts.

[0042] In this embodiment, on the turntable 2, the opened cardboard box is placed on the placing seat 11, and then the electric lifting seat 14 is started to contract. The electric lifting seat 14 drives the protective sleeve 16 to move down into the cardboard box. The protective sleeve 16 drives the positioning assembly 5 to tension and position the cardboard box. At the same time, after all the buffer mechanisms 6 contact the bottom of the cardboard box, under the reverse thrust of the support seat 1, all the buffer mechanisms 6 rotate to the horizontal.

[0043] The spare parts are sequentially and equidistantly conveyed to the upper side of the turntable 2 through the existing belt conveyor. As the first motor drives the turntable 2 to rotate, at this time, the cardboard boxes in each placing seat 11 intermittently move to the lower side of the belt conveyor.

[0044] When the spare parts fall into the middle position of the protective sleeve 16, at this time, the buffer mechanism 6 can buffer the spare parts and guide the spare parts towards the side wall of the protective sleeve 16. Then the control system starts the drive assembly 4 to drive the protective sleeve 16 to rotate. The protective sleeve 16 drives the protective mechanism 8 to push the spare parts in the protective sleeve 16 to flip, so as to avoid continuous extrusion damage of the spare parts and the protective mechanism 8.

[0045] When the spare parts fall towards the side wall of the protective sleeve 16, under the action of the falling force, the spare parts are likely to directly collide with the protective mechanism 8 on the side wall of the protective sleeve 16, damaging the edges and corners of the parts. Moreover, the spare parts are likely to collide back and forth in the protective sleeve 16. At this time, the control system controls the driving assembly 4 to drive the protective sleeve 16 to rotate. While the protective sleeve 16 makes the spare parts flip and unload force through the protective mechanism 8, the control system controls the limiting mechanism 7 to flip into the protective sleeve 16 and vertically limit the spare parts, preventing the spare parts from being excessively squeezed by the protective mechanism 8 or colliding back and forth in the protective sleeve 16. During this process, the limiting mechanism 7 can also generate a magnetic suction force on the spare parts, and all the buffer mechanisms 6 rotate upward to clamp and limit the spare parts; afterwards, the control system adjusts the first motor and the adjusting assembly 3 according to the landing point of the spare parts to ensure that the next spare part can fall into the middle of the protective sleeve 16.

[0046] As Figure 5 shown, as a preferred embodiment of the present invention, the positioning assembly 5 includes a rotating sleeve 51, a fixed seat 52, and a magnetic block 53;

[0047] The rotating sleeve 51 is rotatably connected to the outer wall of the protective sleeve 16. A plurality of fixed seats 52 are fixedly connected to the rotating sleeve 51. The magnetic blocks 53 are slidably connected in the fixed seats 52. The placing seat 11 is provided with a limiting groove 12, and a plurality of limiting plates 13 are arranged around the limiting groove 12. When the electric lifting seat 14 contracts, all the magnetic blocks 53 correspond to the limiting plates 13 one by one.

[0048] In this embodiment, when the protective sleeve 16 moves down into the cardboard box, at this time each magnetic block 53 approaches one side of the limiting plate 13, and the magnetic block 53 adsorbs with the limiting plate 13 to clamp and fix the side walls of the cardboard box, so as to ensure that when the spare parts fall into the cardboard box, the cardboard box maintains a stable shape.

[0049] As Figure 6 shown, as a preferred embodiment of the present invention, the buffer mechanism 6 includes a first rotating seat 61, a rotating rod 62, a rubber sleeve 63, a buffer airbag 64, and a first air duct 65;

[0050] A plurality of first rotating seats 61 are arranged at the bottom of the protective sleeve 16. The first rotating seats 61 are all rotatably connected to the rotating rod 62 through an elastic torsion spring. The rubber sleeves 63 are rotatably connected to the outside of the rotating rod 62. A buffer airbag 64 is arranged at the end of the rotating rod 62 close to the center of the protective sleeve 16. The buffer airbag 64 is communicated with a first air duct 65. The first air duct 65 passes through the rotating rod 62 and the side wall of the protective sleeve 16 and is communicated with the air outlet pipe of the air pump 17.

[0051] In this embodiment, when the protective sleeve 16 falls into the cardboard box, under the reverse thrust of the placing seat 11 at this time, each rotating rod 62 rotates to the horizontal. The rubber sleeves 63 on each rotating rod 62 further limit the cardboard box, and at the same time, the rubber sleeves 63 on each rotating rod 62 protect the spare parts falling into the cardboard box. When the spare parts fall to the middle of the protective sleeve 16, the buffer air bags 64 at one end of the rotating rod 62 jointly buffer the falling parts at this time. And under the elastic force of all the buffer air bags 64, the spare parts rebound towards the side wall of the protective sleeve 16. At this time, the driving assembly 4 drives the protective sleeve 16 to rotate, and the protective sleeve 16 pushes the spare parts to flip through each rubber sleeve 63 and each protection mechanism 8, so as to unload the impact elastic force of the spare parts.

[0052] As Figure 7 shown, as a preferred embodiment of the present invention, the limiting mechanism 7 includes a second rotating seat 71, a connecting ring sleeve 72, a rubber ring 73 and a third motor 74;

[0053] A second rotating seat 71 is arranged at a position near the top of the protective sleeve 16. The second rotating seat 71 is fixedly connected with a third motor 74. The output shaft of the third motor 74 is rotatably connected with a connecting ring sleeve 72. The connecting ring sleeve 72 is internally provided with an electromagnetic ring connected to a micro battery, and the connecting ring sleeve 72 is connected with a rubber ring 73.

[0054] In this embodiment, when the spare parts fall to the side wall position of the protective sleeve 16, at this time, the spare parts contact the protection mechanism 8 at the side wall of the protective sleeve 16. After receiving the signal, the control system controls the third motor 74 to rotate. The third motor 74 drives the connecting ring sleeve 72 to flip towards the inside of the protective sleeve 16. The connecting ring sleeve 72 drives the rubber ring 73 to squeeze down from the upper part of the spare parts. At the same time, the control system controls the electromagnetic ring to be energized briefly, and the electromagnetic ring in the connecting ring sleeve 72 generates a magnetic suction force on the spare parts, so that the spare parts are quickly adsorbed and fixed, and the rubber sleeve 63, the connecting ring sleeve 72 and the protection mechanism 8 jointly protect the spare parts.

[0055] As Figure 8 shown, as a preferred embodiment of the present invention, the protection mechanism 8 includes a third rotating seat 81, a protection plate 82, a spring 83 and a protection air bag 84;

[0056] A plurality of third rotating seats 81 are fixedly connected to the inner wall of the protective sleeve 16. Each third rotating seat 81 is rotatably connected with a protection plate 82. All the protection plates 82 are inclined in the same direction. A spring 83 is connected between the third rotating seat 81 and the protection plate 82. A protection air bag 84 is arranged in the protection plate 82. A plurality of strip-shaped grooves for accommodating the protection air bag 84 are formed on the surface of the protection plate 82. The protection air bag 84 is communicated with the air outlet pipe of the air pump 17 through a second air pipe 85.

[0057] In this embodiment, when the protective sleeve 16 rotates, the protective sleeve 16 drives all the protective plates 82 to rotate. When the spare parts come into contact with the protective plate 82, first, the airbag 84 in the protective plate 82 elastically protects the spare parts. And when the protective plate 82 rotates, the protective plate 82 can push the spare parts to turn over, thereby dissipating the impact force exerted by the spare parts.

[0058] After the spare parts are packaged, at this time, the driving component 4 drives the protective sleeve 16 to rotate back to the initial position, so that each protective plate 82 rotates back to the original position.

[0059] As Figure 3 shown, as a preferred embodiment of the present invention, a plurality of guide grooves 18 are provided on the surface of the turntable 2 along the diameter direction, and the base of each placing seat 11 is correspondingly slidably connected in a guide groove 18. The adjusting component 3 includes a second motor 31 and a threaded rod 32. A second motor 31 is fixedly provided on one side of each guide groove 18, the output shaft of the second motor 31 is fixedly connected with a threaded rod 32, and the threaded rods 32 are all threadedly connected with the base of the placing seat 11.

[0060] In this embodiment, when the second motor 31 is started, the second motor 31 drives the threaded rod 32 to rotate. The threaded rod 32 drives the placing seat 11 to move in the guide groove 18 through a threaded transmission manner, thereby changing the distance between the carton and the belt conveyor when the spare parts fall.

[0061] As Figure 5 shown, as a preferred embodiment of the present invention, an annular airbag 9 is connected to the outer wall of the protective sleeve 16, and the annular airbag 9 is communicated with an air pump 17 through a third air duct.

[0062] In this embodiment, when the protective sleeve 16 rotates, at this time, the annular airbag 9 can always elastically tension the carton in the carton, thereby improving the stability of the carton.

[0063] As a preferred embodiment of the present invention, the control system includes:

[0064] A monitoring module, which includes a pressure sensor and a torsion sensor. Pressure sensors are arranged at the joints of the buffer airbag 64 and the rotating rod 62, and torsion sensors are arranged at the joints of the protective plate 82 and the spring 83;

[0065] A processing module, which is used to judge the pressure signal of the pressure sensor and the torsion signal of the torsion sensor, and form a judgment message;

[0066] A control module, which controls the first motor, the adjusting component 3, the driving component 4, the limiting mechanism 7 and the air pump 17 according to the judgment message of the processing module.

[0067] In this embodiment, when the spare parts fall into the middle of the protective sleeve 16, the pressure sensor on the lower side of the buffer airbag 64 emits a signal first. After receiving the signal, the processing module immediately controls the driving component 4 to drive the protective sleeve 16 to rotate. The protective sleeve 16 buffers and relieves the force on the spare parts through the protection mechanism 8, and according to the magnitude of the pressure of the pressure sensor, the control system adjusts the volume of the air pressure increased by the air pump 17 into the protection airbag 84, so as to enhance the protection effect on the spare parts;

[0068] When the spare parts fall to the side wall position of the protective sleeve 16, the torsion sensor is pre-pressed and emits a signal at this time, while the pressure sensor does not emit a signal. After receiving the signal, the processing module immediately controls the driving component 4 to drive the protective sleeve 16 to rotate. The protective sleeve 16 buffers and relieves the force on the spare parts through the protection mechanism 8, and the processing module controls the limiting mechanism 7 to flip into the protective sleeve 16, so as to adsorb and fix the spare parts. At this time, the rubber sleeve 63, the rubber ring 73 and the protection airbag 84 jointly provide elastic protection for the spare parts;

[0069] When the spare parts fall to the side wall position of the protective sleeve 16, according to the position of the torsion sensor on the protective plate 82, the processing module can determine the landing point of the spare parts in the protective sleeve 16. By adjusting the rotation angle of the first motor for each intermittent rotation, the intermittent rotation angle of the rotating table 2 is adjusted, and the position of the placing seat 11 on the rotating table 2 is adjusted through the adjusting component 3. Finally, the position of the cardboard box under the belt conveyor device when the spare parts fall is changed, so that the spare parts can always fall into the middle of the cardboard box when they fall, avoiding the spare parts falling outside the cardboard box or the continuous collision between the spare parts and the side wall of the cardboard box.

[0070] In the present invention, through the cooperation of the protective sleeve 16 and each buffer mechanism 6 and protection mechanism 8, not only the buffer protection of the spare parts is realized while the spare parts are falling, but also the cardboard box is effectively stabilized when the spare parts are falling; further, compared with the comparative document, the cooperation of the protective sleeve 16, each buffer mechanism 6 and protection mechanism 8 minimizes the occupation of the internal space of the cardboard box. When the electric lifting seat 14 extends to drive the protective sleeve 16 to disengage from the cardboard box, at this time, each buffer mechanism 6 gradually returns to a conical shape under the drive of the elastic torsion spring, and the spare parts can also be guided and protected through each buffer mechanism 6, so that the spare parts are stably maintained at the center position of the cardboard box.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
