Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular relates to a material packing device. Background Art

[0002] In the machinery industry, screws, as one of the most commonly used fasteners in industry, are widely used in various mechanical components. In the prior art, when packing screws, in order to facilitate linkage with counting equipment, an automatic packaging machine is usually used to encapsulate a certain number of screws and matching nuts in a packaging bag, and then the packaging bag usually falls freely and is conveyed to the packing process through a conveyor belt.

[0003] Currently, for the convenience of operation, the packaging bag containing screws and nuts is usually directly placed in a packing box, and the packaging bags are arranged in a disorderly manner in the packing box, which results in the space of the packing box not being fully utilized. Currently, the packaging bags are usually placed in the packing box by manual counting, or the packing box is directly placed at the end of the conveyor belt to make the packaging bags directly fall into the packing box. The former method is convenient for counting the number of parts in the packing box, but it is prone to counting errors, resulting in deviations in the number of parts in the packing box, and the efficiency of manual packing is too low, which is not conducive to the rapid progress of production. The latter method has a higher efficiency, but it is not convenient for accurately counting the packaging bags, and it may also cause deviations in the number of parts in the packing box.

[0004] If a manipulator is used to clamp and transfer the packaging bag containing screws and nuts to the packing box, although it is relatively convenient and can ensure the space utilization rate of the packing box, it still needs to accurately identify the position of the packaging bag on the conveyor belt, which makes the equipment cost higher, and only one packaging bag can be clamped at a time, making it difficult to adapt to a faster conveying speed and not conducive to the rapid progress of production. In order to improve the efficiency, only the number of manipulators can be increased, which will also make the equipment cost too high. Summary of the Invention

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] As Figures 1 to 9 shown, an embodiment of the present application provides a material packing device, including: a workbench 100, a collection mechanism 200, and a transfer mechanism 300.

[0034] The top surface of the workbench 100 is provided with a through groove 101 that penetrates through one side. Above the workbench 100, there is a discharge pipe 102 located on the opening side of the through groove 101, which is used to discharge downward the packaging bags containing screws and matching nuts. Both ends of the top surface of the workbench 100 are provided with recesses 103 that penetrate up and down. The recesses 103 are located on both sides of the through groove 101, and cartons are arranged in the recesses 103; The collection mechanism 200 includes a support shaft 201 provided on the opening side of the through groove 101 and having an axis parallel to its length direction. Two symmetrically arranged mounting blocks 202 are sleeved on the support shaft 201. The mounting blocks 202 are reciprocally movable along its axis and rotatable around its axis. A plurality of support plates 203 with an L-shaped cross-section are arranged at equal intervals in the circumferential direction on the peripheral side of the mounting block 202. A limiting plate 204 with a concave cross-section is movably arranged on the support plate 203 along its width direction. A rectangular space is formed between the limiting plate 204 and the support plate 203 for accommodating the packaging bags arranged in a row at one time. When it is necessary to transfer the packaging bags in the discharge pipe 102 to the rectangular space formed by the limiting plate 204 and the support plate 203, the limiting plate 204 on one of the mounting blocks 202 is aligned with the lower end of the discharge pipe 102, and a pressing plate 205 is movably arranged on the inner side of the limiting plate 204 along its thickness direction, which is used to press the materials to prevent the packaging bags from shaking arbitrarily in the rectangular space and can also adapt to packaging bags of different volumes; The transfer mechanism 300 includes two symmetrically arranged carrier plates 301 provided at both ends of the through groove 101 and movably arranged in the vertical direction, which are used to receive the packaging bags from the rectangular space. Above the carrier plate 301, there is a moving frame 302 movably arranged along the length direction of the workbench 100. A plurality of suction cups 303 movably arranged in the vertical direction are arranged on the moving frame 302, which are used to suck the packaging bags on the carrier plate 301 and transfer them to the cartons in batches.

[0035] Specifically, as Figures 1 - 3 , Figure 5 shown, in order to facilitate driving the movement of the two mounting blocks 202 simultaneously, the inner sides of the mounting blocks 202 are rotatably mounted on a connecting ring 206. The connecting ring 206 is sleeved on the support shaft 201 and connected to one end of a moving rod 207. The moving rod 207 is sleeved on a first guiding rod 239 and connected to the moving end of a first horizontal linear mechanism. The first guiding rod 239 and the first horizontal linear mechanism are both mounted on the workbench 100. The first horizontal linear mechanism is arranged along the length direction of the workbench 100. After a sufficient number of packaging bags are carried in the rectangular space formed by one of the limiting plates 204 and the support plate 203, the first horizontal linear mechanism is used to drive the moving rod 207 to move along the axis of the support shaft 201. At this time, one of the mounting blocks 202 will move away from below the discharge pipe 102, and the other mounting block 202 will move to below the discharge pipe 102, so that the rectangular space formed by the limiting plate 204 on the other mounting block 202 and the support plate 203 is aligned with the discharge pipe 102.

[0036] Specifically, as Figures 2 - 5 shown, in order to ensure that the mounting block 202 can move along the axis of the support shaft 201 and can also rotate, a plurality of equally spaced positioning grooves 208 are provided on the outer side of the mounting block 202 in the circumferential direction. After one of the mounting blocks 202 is removed from below the discharge pipe 102, a positioning pin 209 is inserted through the positioning groove 208 of one of the mounting blocks 202, and the positioning pin 209 is installed on the side wall of the driven gear 210. The driven gear 210 is installed on the collar 211 and meshes with the driving gear 212. The collar 211 is rotatably installed on the convex shaft 213. The convex shaft 213 is connected to the end of the support shaft 201 and is installed on the workbench 100. The driving gear 212 is installed on the transmission shaft 214. One end of the transmission shaft 214 is connected to the output end of the power device. The transmission shaft 214 and the power device are both installed at the bottom of the workbench 100. When it is necessary to drive the mounting block 202 to rotate so that the packaging bag in the rectangular space formed by the limiting plate 204 and the support plate 203 changes from the vertical state to the horizontal state, the power device can be used to drive the transmission shaft 214 to rotate. Under the meshing transmission of the driving gear 212 and the driven gear 210, the mounting block 202 will be driven to rotate.

[0037] Specifically, as Figure 2 、 Figure 5 shown, in order to prevent the mounting block 202 from rotating under its own gravity during the movement process, resulting in the rectangular space formed by the limiting plate 204 and the support plate 203 not being aligned with the discharge pipe 102, two spaced-apart clamping plates 104 are provided in the through groove 101 in the vertical direction. During the process of the mounting block 202 moving along the axis of the support shaft 201 and before the positioning pin 209 is inserted through the positioning groove 208 of one of the mounting blocks 202, at least a part of the support plate 203 on one of the mounting blocks 202 is located between the two clamping plates 104 and is in contact with the clamping plates 104 on both the upper and lower sides. The other mounting block 202 is gradually disengaged from the driven gear 210, and before being completely disengaged, the support plate 203 on the other mounting block 202 is located between the two clamping plates 104. When the positioning pin 209 is completely inserted through the positioning groove 208 of one of the mounting blocks 202, the support plate 203 of one of the mounting blocks 202 is located in the area outside the clamping plate 104, and the other mounting block 202 is located directly below the discharge pipe 102, and the rectangular space formed by the limiting plate 204 and the support plate 203 is aligned with the discharge pipe 102.

[0038] More specifically, as Figure 2As shown, in order to prevent the packaging bags in the discharge pipe 102 from directly slipping during the movement of the installation block 202, a baffle is provided in the discharge pipe 102. When the installation block 202 is moved away from directly below the discharge pipe 102, the baffle closes the lower part of the discharge pipe 102, and when the installation block 202 is located directly below the discharge pipe 102, the baffle can be removed.

[0039] Specifically, as Figures 2 - 4 shown, a pressure rod 215 is provided on the pressing plate 205. The pressure rod 215 passes through the limiting plate 204 and is arranged in the support 216. The support 216 is installed on the limiting plate 204. A retaining ring 217 is provided on the pressure rod 215 for abutting against the limiting plate 204. A first spring 218 is sleeved on the pressure rod 215 between the retaining ring 217 and the support 216. Both ends of the first spring 218 abut against the support 216 and the retaining ring 217 respectively and are always in a compressed state. Under the action of the first spring 218, the pressing plate 205 always has a tendency to move towards the bottom of the support plate 203, so as to be able to press the packaging bags in the rectangular space surrounded by the support plate 203 and the limiting plate 204, preventing the packaging bags therein from shifting during the rotation of the installation block 202, facilitating subsequent transfer operations.

[0040] Specifically, as Figures 2 - 4As shown in the figure, a partition plate 107 is provided in the discharge pipe 102 to limit the packaging bags in the discharge pipe 102. To ensure that the partition plate 107 can be aligned with the pressing plate 205 so that the packaging bags in the discharge pipe 102 can smoothly enter the rectangular space formed by the support plate 203 and the limit plate 204, a moving block 219 is provided at the end of the pressing rod 215. A limit hole 220 is arranged along the axis of the support shaft 201 in the moving block 219. When one of the mounting blocks 202 is located directly below the discharge pipe 102 and the rectangular space formed by the support plate 203 and the limit plate 204 is aligned with the lower end of the discharge pipe 102, a limit block 105 is inserted through the limit hole 220 on the vertically positioned pressing plate 205 of one of the mounting blocks 202. Both ends of the limit block 105 are provided with inclined surfaces, and the inclined surfaces face the outside of the workbench 100. The side of the limit block 105 is connected to the mounting plate 106. The mounting plate 106 includes two horizontal sections and a vertical section connecting the two horizontal sections. The limit block 105 is connected to one of the horizontal sections, and a through portion penetrating to the outside of the moving block 219 is provided on the side of the limit hole 220 for passing through one of the horizontal sections. The other horizontal section passes through the discharge pipe 102, and the end is connected to the partition plate 107. When one of the support plates 203 is aligned with the lower end of the discharge pipe 102, the partition plate 107 is aligned with the pressing plate 205. The vertical section is sleeved on the cross bar 108 and the screw 109 and locked with nuts. The cross bar 108 and the screw 109 are both installed on the discharge pipe 102. During the actual operation process, when the mounting block 202 is moved towards the discharge pipe 102, the edge of the limit hole 220 will contact the inclined surface of the limit block 105. As the mounting block 202 continues to move, the moving block 219 is forced to move, driving the pressing plate 205 to move synchronously. At this time, the first spring 218 is further compressed, thereby realizing the movement of the pressing plate 205 so that the pressing plate 205 can be aligned with the partition plate 107; According to different production requirements, different numbers of screws and nuts are packaged in the packaging bags. The packaging bags usually adopt a unified specification for their sizes, while the volume and thickness of the packaging bags will change. To be able to adapt to different production requirements, the mounting plate 106 can be moved by rotating the nut, thereby adjusting the position of the partition plate 107, so that it can adapt to packaging bags of different volumes and thicknesses. Then, the mounting plate 106 can be locked with nuts. And as the mounting plate 106 moves, the position of the limit block 105 will also change. Thus, during the movement of the mounting block 202, the moving distance of the pressing plate 205 will also change. The moving distance of the pressing plate 205 is equal to the distance between the two end faces of the limit block 105 minus the moving distance of the mounting plate 106 towards the discharge pipe 102, thereby ensuring that the pressing plate 205 can always be aligned with the partition plate 107, and further ensuring that the packaging bags in the discharge pipe 102 can smoothly enter the rectangular space formed by the support plate 203 and the limit plate 204.

[0041] Specifically, asFigures 2 - 4 As shown in the figure, an L-shaped plate 221 is provided on the support plate 203. A connecting rod 222 is passed through the L-shaped plate 221. A support plate 223 is provided at one end of the connecting rod 222 facing the bearing plate 301. The support plate 223 is connected to the limiting plate 204. A first retaining ring 224 is provided at the other end of the connecting rod 222. A second spring 225 is sleeved on the connecting rod 222. Both ends of the second spring 225 are respectively abutted against the first retaining ring 224 and the L-shaped plate 221, and is always in a compressed state. Under the action of the second spring 225, the limiting plate 204 can always have a tendency to move towards the side wall of the support plate 203. Thus, in the absence of external force, a rectangular space can be stably formed between the limiting plate 204 and the support plate 203. When it is necessary to transfer the packaging bag in the rectangular space to the bearing plate 301, an external force towards the bearing plate 301 is applied to the limiting plate 204, so that the limiting plate 204 moves above the bearing plate 301. At this time, the second spring 225 is further compressed, and the packaging bag in the rectangular space is moved onto the bearing plate 301. Then the bearing plate 301 is moved downward, and the packaging bag can be removed from the area of the limiting plate 204, and under the action of the pressing plate 205, it can be ensured that the packaging bag can stably move downward with the bearing plate 301, realizing the transfer of the packaging bag. Finally, the external force applied to the limiting plate 204 is released, and the limiting plate 204 will reset under the action of the second spring 225.

[0042] Specifically, as Figures 3 - 5 shown, side plates 226 are provided on the moving rod 207. Push plates 227 are provided on both sides of the side plates 226 for pushing the limiting plate 204. One end of the push plate 227 is sleeved on the second guide rod 228. For the sliding between the push plate 227 and the second guide rod 228, a key groove and key pin structure can be used for sliding limit to prevent the push plate 227 from deflecting under its own gravity. Both ends of the second guide rod 228 are installed on the connecting plate 229, and the connecting plate 229 is installed on the workbench 100. Fourth springs 230 are sleeved on both ends of the second guide rod 228. Both ends of the fourth spring 230 are respectively abutted against the connecting plate 229 and the push plate 227, and are always in a compressed state. Under the action of the fourth spring 230, the push plate 227 always has a tendency to move away from the connecting plate 229. Then, in the absence of external force, the push plate 227 will abut against the side plate 226. Thus, when the moving rod 207 moves, the push plate 227 will also move synchronously; and convex blocks 231 are provided on both sides of the side plate 226. When the push plate 227 does not contact the first retaining ring 224, the push plate 227 is sleeved on the convex block 231 to provide further support for the push plate 227. When it is necessary to push the limiting plate 204 to move, only an external force opposite to the elastic force direction of the fourth spring 230 needs to be applied to one of the push plates 227.

[0043] Specifically, as Figures 3 - 6 ​As shown, a slide bar 232 is provided between the connecting plates 229. Two sliders 233 are sleeved on the slide bar 232. The slide bar 232 can provide guiding and supporting functions for the movement of the sliders 233. The sliders 233 are connected to the moving ends of the second horizontal linear mechanism. The second horizontal linear mechanism is installed on the connecting plates 229. A vertically arranged ejector rod 234 is inserted through the sliders 233. A push block 235 is provided at the lower end of the ejector rod 234. The side of the push block 235 away from the moving frame 302 is arc-shaped. When one of the mounting blocks 202 is directly below the discharge pipe 102, one of the push blocks 235 is located between the two push plates 227 for pushing one of the push plates 227. A fifth spring 236 is sleeved on the ejector rod 234. The two ends of the fifth spring 236 respectively abut against the push block 235 and the slider 233 and are always in a compressed state. A stop block 237 is provided at the upper end of the ejector rod 234 for abutting against the top surface of the slider 233. When the mounting block 202 is removed from directly below the discharge pipe 102, the push plate 227 moves synchronously with it. The arc surface of the push block 235 will contact the edge above the push plate 227. As the push plate 227 continues to move, it will force the push block 235 to move upward, and the fifth spring 236 is further compressed until the push block 235 completely passes one of the push plates 227 and is located between the two push plates 227. Then the push block 235 will move downward under the action of the fifth spring 236. Then, the second horizontal linear mechanism is used to drive the push block 235 to move towards the bearing plate 301, so as to push the push plate 227 to move synchronously and drive the limiting plate 204 to move towards the bearing plate 301.

[0044] Specifically, as Figure 1 、 Figures 5 - 6 、 Figure 9 shown, in order to avoid interference between the push plate 227 and the push block 235 during the reciprocating movement of the mounting block 202, a through hole 238 is provided on the side surface of the stop block 237. The upper part of the through hole 238 is provided with an inclined surface. One end of the moving frame 302 is provided with a second push rod 313. During the movement of the moving frame 302 towards the bearing plate 301, the second push rod 313 will penetrate into the through hole 238 and will first contact the inclined surface, thereby forcing the stop block 237 to move upward until the second push rod 313 completely passes through the through hole 238. At this time, the fifth spring 236 is further compressed, and the push block 235 is moved above the push plate 227 and will not block the reset of the push plate 227.

[0045] Specifically, as Figure 1 、 Figures 7 - 8As shown, a U-shaped plate 304 is provided on the top surface of the carrier plate 301. The opening of the U-shaped plate 304 faces the collection mechanism 200 and is used to limit the position of the material. A convex plate 305 is provided on the outside of the U-shaped plate 304. The convex plate 305 is sleeved on the vertical rod 306. The lower end of the vertical rod 306 is installed on the chassis 307. The chassis 307 is installed at the bottom of the workbench 100. A third spring 308 is sleeved on the vertical rod 306. The two ends of the third spring 308 respectively abut against the chassis 307 and the convex plate 305 and are always in a compressed state. A second retaining ring 309 is provided at the upper end of the vertical rod 306 and is used to abut against the convex plate 305. When the carrier plate 301 is at the highest point of its stroke, the top surface thereof is flush with the top surface of the horizontal part of the support plate 203. During the process of transferring the packaging bag in the limiting plate 204 onto the carrier plate 301, in order to prevent the limiting plate 204 from bringing the packaging bag back when it resets, a downward force is applied to the convex plate 305, so that the third spring 308 is further compressed and the carrier plate 301 moves downward until the top of the U-shaped plate 304 is completely lower than the bottom of the limiting plate 204. At this time, the moving frame 302 is moved towards the carrier plate 301, so that the second push rod 313 penetrates into the through hole 238, the push block 235 moves upward, the push plate 227 resets under the action of the fourth spring 230, and the limiting plate 204 resets under the action of the second spring 225. Then, the moving frame 302 continues to move towards the carrier plate 301 until the moving frame 302 is located above the carrier plate 301, so as to facilitate the suction cup 303 to adsorb the packaging bag on the carrier plate 301.

[0046] Specifically, as Figures 7 - 9 shown, the suction cup 303 is installed on the lifting rod 310. The lifting rod 310 passes through the moving frame 302 and is installed on the lifting plate 311. The lifting plate 311 is connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is installed on the moving frame 302. The moving frame 302 is connected to the moving end of the third horizontal linear mechanism. The third horizontal linear mechanism is installed on the workbench 100 and is arranged along its length direction. When the moving frame 302 is directly above the carrier plate 301, the vertical lifting mechanism is used to drive the lifting plate 311 to move downward to adsorb the packaging bag on the carrier plate 301. Then, the lifting plate 311 is moved upward, and the moving frame 302 is moved above the box, and the packaging bags adsorbed by the suction cup are neatly arranged in the box.

[0047] Specifically, as Figure 1 、 Figures 7 - 9As shown, first push rods 312 are provided at both ends of the moving frame 302. The first push rod 312 includes two horizontal sections and a transition section connecting the two horizontal sections. During the process of the moving frame 302 moving towards the bearing plate 301, the transition section of the first push rod 312 will first contact the edge at the top of the convex plate 305. As the moving frame 302 continues to move, it will force the convex plate 305 to move downward and drive the bearing plate 301 to move downward. At this time, the third spring 308 is further compressed until the top surface of the convex plate 305 contacts the lower horizontal section of the first push rod 312. At this time, the packaging bag in the limit plate 204 has been completely transferred to the bearing plate 301, but at this time, the limit plate 204 is still directly above the bearing plate 301 and will hinder the moving frame 302 from being directly above the bearing plate 301. Then, continue to move the moving frame 302 towards the bearing plate 301 so that the second push rod 313 penetrates into the through hole 238 of the stopper 237, causing the push block 235 to move upward, then the limit plate 204 and the push plate 227 will automatically reset. After that, the moving frame 302 can smoothly move above the bearing plate 301 to adsorb the packaging bag on the bearing plate 301.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
