Description

TECHNICAL FIELD

[0001] The present application relates to the packaging technical field, especially to a material packaging device. BACKGROUND

[0002] In the mechanical industry, screws are widely used in various mechanical parts as the most commonly used fasteners in the industry. In the prior art, when packaging screws, in order to facilitate the linkage with the counting device, an automatic packaging machine is usually used to package a certain number of screws and matching nuts in a packaging bag, and then the packaging bag is usually allowed to fall freely and is conveyed to the boxing process through a conveying belt.

[0003] At present, in order to facilitate operation, the packaging bag containing screws and nuts is usually directly placed in the packaging box, and the packaging bags are arranged in a disorderly manner in the packaging box, which results in that the space of the packaging box cannot be fully utilized. At present, the packaging bag is placed in the packaging box by manual counting, or the packaging box is directly placed at the end of the conveying belt, so that the packaging bag directly falls into the packaging box. The former method is convenient for counting the number of parts in the packaging box, but is prone to counting errors, which causes the number of parts in the packaging box to deviate. The efficiency of manual boxing is too low, which is not conducive to the rapid production. The latter method is relatively high in efficiency, but is not convenient for accurate counting of the packaging bag, and also may cause the number of parts in the packaging box to deviate.

[0004] If a mechanical hand is used to clamp and transfer the packaging bag containing screws and nuts to the packaging box, although it is relatively convenient and can ensure the space utilization rate of the packaging box, it is still necessary to accurately identify the position of the packaging bag on the conveying belt, which results in high equipment cost. Moreover, only one packaging bag can be clamped at a time, which is difficult to adapt to a faster conveying speed and is not conducive to the rapid production. In order to improve the efficiency, the number of mechanical hands needs to be increased, which also results in high equipment cost. SUMMARY

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application are described in detail below with reference to the drawings, but the embodiments described in the present application are part of the embodiments of the present application, not all the embodiments of the present application.

[0034] As shown in Figures 1-9 the present application provides a material packaging device, which comprises a workbench 100, a collecting mechanism 200 and a transfer mechanism 300.

[0035] The top surface of the workbench 100 is provided with a through groove 101 on one side, and a discharge pipe 102 is arranged above the workbench 100 and located at the opening side of the through groove 101, which is used to discharge the packaging bags containing screws and matched nuts downward. The top surface of the workbench 100 is provided with recesses 103 at both ends, which are located on both sides of the through groove 101, and a paper box is arranged in the recesses 103. The collecting mechanism 200 includes a support shaft 201 arranged at the opening side of the through groove 101 and having an axis parallel to the length direction of the through groove 101. Two mounting blocks 202 are symmetrically arranged on the support shaft 201 and are arranged to reciprocate along the axis of the support shaft 201 and rotate around the axis. A plurality of support plates 203 are arranged on the circumference of the mounting blocks 202 and are arranged at equal intervals in the circumferential direction of the mounting blocks 202 and have an L-shaped cross section. A limiting plate 204 is arranged on the support plate 203 and is arranged to move in the width direction of the support plate 203 and has a concave cross section. The limiting plate 204 and the support plate 203 form a rectangular space therebetween, which is used to accommodate the packaging bags arranged once. 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. The inner side of the limiting plate 204 is provided with a pressing plate 205 arranged to move in the thickness direction of the limiting plate 204, which is used to press the material and avoid the packaging bags from shaking randomly in the rectangular space, and can also adapt to packaging bags of different volumes. The transfer mechanism 300 includes two bearing plates 301 symmetrically arranged at both ends of the through groove 101 and arranged to move in the vertical direction, which are used to receive the packaging bags from the rectangular space. A moving frame 302 is arranged above the bearing plate 301 and is arranged to move in the length direction of the workbench 100. A plurality of suction cups 303 are arranged on the moving frame 302 and are arranged to move in the vertical direction, which are used to suck the packaging bags on the bearing plate 301 and transfer them to the paper box in batches.

[0036] Specifically, as shown in Figures 1-3 , Figure 5 In order to facilitate the movement of the two mounting blocks 202 at the same time, the inner side of the mounting block 202 is 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 guide rod 239 and connected to the moving end of a first horizontal linear mechanism, the first guide rod 239 and the first horizontal linear mechanism are both mounted on the workbench 100 and arranged in the length direction of the workbench 100. After a sufficient amount of packaging bags are received in the rectangular space formed by one of the limiting plates 204 and the support plates 203, the moving rod 207 is driven to move along the axis of the support shaft 201 by the first horizontal linear mechanism. At this time, one of the mounting blocks 202 moves away from below the discharge pipe 102, and the other mounting block 202 moves to below the discharge pipe 102, so that the rectangular space formed by the limiting plate 204 and the support plate 203 on the other mounting block 202 is aligned with the discharge pipe 102.

[0037] Specifically, as shown in Figures 2-5 In order to ensure that the mounting block 202 can move along the axis of the support shaft 201 and rotate, a plurality of equidistantly arranged positioning grooves 208 are arranged on the outer side of the mounting block 202 in the circumferential direction, a positioning pin 209 is arranged in one of the positioning grooves 208 of one of the mounting blocks 202 after the mounting block 202 is removed from below the discharge pipe 102, the positioning pin 209 is arranged on the side wall of a driven gear 210, the driven gear 210 is arranged on a sleeve 211, and the driven gear 210 is engaged with a driving gear 212, the sleeve 211 is rotatably arranged on a protruding shaft 213, the protruding shaft 213 is connected to the end of the support shaft 201 and is arranged on the workbench 100, the driving gear 212 is arranged on a transmission shaft 214, one end of the transmission shaft 214 is connected to the output end of a power device, and the transmission shaft 214 and the power device are arranged on 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 a vertical state to a horizontal state, the power device can be used to drive the transmission shaft 214 to rotate, and the mounting block 202 will be driven to rotate under the engagement transmission of the driving gear 212 and the driven gear 210.

[0038] Specifically, as shown in Figure 2 、 Figure 5 In order to avoid the rotation of the mounting block 202 under the action of its own gravity during the movement of the mounting block 202, which causes the rectangular space formed by the limiting plate 204 and the support plate 203 to be misaligned with the discharge pipe 102, two spaced-apart clamping plates 104 are arranged in the vertical direction in the through groove 101. During the movement of the mounting block 202 along the axis of the support shaft 201, and before the positioning pin 209 is arranged in 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 contacts the clamping plates 104 on the upper and lower sides, and the other mounting block 202 gradually disengages from the driven gear 210, and before complete disengagement, the support plate 203 on the other mounting block 202 is located between the two clamping plates 104, and after the positioning pin 209 is completely arranged in 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.

[0039] More specifically, as shown in Figure 2As shown, to prevent the packaging bag in the discharge pipe 102 from sliding down directly during the movement of the mounting block 202, a baffle is installed in the discharge pipe 102. When the mounting block 202 is moved away from directly below the discharge pipe 102, the baffle closes the bottom of the discharge pipe 102. When the mounting block 202 is directly below the discharge pipe 102, the baffle can be removed.

[0040] Specifically, such as Figures 2-4 As shown, a pressure rod 215 is provided on the pressure plate 205. The pressure rod 215 passes through the limiting plate 204 and is installed in the bracket 216. The bracket 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 bracket 216. The two ends of the first spring 218 abut against the bracket 216 and the retaining ring 217 respectively, and are always in a compressed state. Under the action of the first spring 218, the pressure plate 205 always tends to move towards the bottom of the support plate 203, so as to apply pressure to the packaging bag in the rectangular space enclosed by the support plate 203 and the limiting plate 204, and prevent the packaging bag from shifting during the rotation of the mounting block 202, so as to facilitate subsequent transfer operations.

[0041] Specifically, such as Figures 2-4As shown, the partition plate 107 is arranged in the discharge pipe 102, and is used for limiting the packaging bag in the discharge pipe 102. In order to ensure that the partition plate 107 can be aligned with the pressing plate 205, so that the packaging bag in the discharge pipe 102 can smoothly enter the rectangular space surrounded by the support plate 203 and the limiting plate 204, the moving block 219 is arranged at the end of the pressing rod 215, the limiting hole 220 arranged along the axis of the support shaft 201 is arranged in the moving block 219, when one of the mounting blocks 202 is located directly below the discharge pipe 102, and the rectangular space surrounded by the support plate 203 and the limiting plate 204 is aligned with the lower end of the discharge pipe 102, the limiting block 105 is arranged in the limiting hole 220 on the pressing plate 205 of the mounting block 202 in the vertical state, and the limiting block 105 is provided with inclined surfaces at both ends, and the inclined surfaces are directed to the outside of the workbench 100, the limiting block 105 is connected to the mounting plate 106 on the side surface, the mounting plate 106 comprises two horizontal sections and a vertical section connecting the two horizontal sections, the limiting block 105 is connected to one of the horizontal sections, and the side surface of the limiting hole 220 is provided with a through portion penetrating to the outside of the moving block 219, for penetrating through one of the horizontal sections, and the other horizontal section penetrates through the discharge pipe 102, and the end is connected with 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 rod 108 and the screw rod 109, and is locked by the nut, and the cross rod 108 and the screw rod 109 are both mounted on the discharge pipe 102. In the actual operation process, when the mounting block 202 is moved towards the discharge pipe 102, the edges of the limiting hole 220 will be in contact with the inclined surfaces of the limiting block 105, and with the continuous movement of the mounting block 202, the moving block 219 is forced to move, and the pressing plate 205 is synchronously moved, at this time, the first spring 218 is further compressed, so as to realize the movement of the pressing plate 205, so that the pressing plate 205 can be aligned with the partition plate 107.

[0042] According to different production requirements, different numbers of screws and nuts can be packaged in the packaging bag, and the size of the packaging bag is usually uniform, but the volume and thickness of the packaging bag can be changed. In order to adapt to different production requirements, the mounting plate 106 can be moved by rotating the nut, so as to adjust the position of the partition plate 107, so that the packaging bag of different volume and thickness can be adapted, and then the mounting plate 106 is locked by the nut, and with the movement of the mounting plate 106, the position of the limiting block 105 also changes, so that the distance of the movement of the pressing plate 205 also changes in the process of the movement of the mounting block 202. The distance of the movement of the pressing plate 205 is equal to the distance between the two end surfaces of the limiting block 105 minus the distance of the movement of the mounting plate 106 towards the discharge pipe 102, so as to ensure that the pressing plate 205 can be always aligned with the partition plate 107, and further ensure that the packaging bag in the discharge pipe 102 can smoothly enter the rectangular space surrounded by the support plate 203 and the limiting plate 204.

[0043] Specifically, as shown in Figures 2-4 The support plate 203 is provided with an L-shaped plate 221, a connecting rod 222 is arranged in the L-shaped plate 221, one end of the connecting rod 222 is provided with a supporting plate 223 facing the bearing plate 301, the supporting plate 223 is connected with the limiting plate 204, the other end of the connecting rod 222 is provided with a first stop ring 224, a second spring 225 is sleeved on the connecting rod 222, the two ends of the second spring 225 abut against the first stop ring 224 and the L-shaped plate 221 respectively, and are always in a compressed state. Under the action of the second spring 225, the limiting plate 204 always has a tendency to move towards the side wall of the support plate 203, so that the limiting plate 204 and the support plate 203 can stably form a rectangular space under the condition that no external force is applied. When it is needed to transfer the packaging bag in the rectangular space to the bearing plate 301, an external force is applied to the limiting plate 204 towards the bearing plate 301, so that the limiting plate 204 moves above the bearing plate 301. At this time, the second spring 225 is further compressed, and then the packaging bag in the rectangular space is moved to the bearing plate 301. After the bearing plate 301 is moved downward, the packaging bag can be moved out of the area of the limiting plate 204, and under the action of the pressing plate 205, the packaging bag can stably follow the bearing plate 301 to move downward, so that the transfer of the packaging bag is realized. Finally, the external force applied to the limiting plate 204 is removed, and the limiting plate 204 is reset under the action of the second spring 225.

[0044] Specifically, as shown in Figures 3-5 The moving rod 207 is provided with a side plate 226, and a push plate 227 is arranged on both sides of the side plate 226 for pushing the limiting plate 204. One end of the push plate 227 is sleeved on a second guide rod 228, and the sliding between the push plate 227 and the second guide rod 228 can be limited by a key groove and a key pin structure to avoid the deflection of the push plate 227 under the action of its own gravity. The second guide rod 228 is installed on a 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, and the two ends of the fourth springs 230 abut against the connecting plate 229 and the push plate 227 respectively, and are always in a compressed state. Under the action of the fourth springs 230, the push plate 227 always has a tendency to move away from the connecting plate 229, so that the push plate 227 will abut against the side plate 226 when there is no external force, so that the push plate 227 will move synchronously with the moving rod 207 when the moving rod 207 moves.

During the movement of the moving frame 302 towards the bearing plate 301, the transition section of the first push rod 312 will first contact the edge of the top of the convex plate 305. With the continuous movement of the moving frame 302, the convex plate 305 will be forced to move downwards, and the bearing plate 301 will be driven to move downwards. 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.

Therefore, the moving frame 302 is continuously moved towards the bearing plate 301, so that the second push rod 313 penetrates into the perforation 238 of the stop block 237, and the push block 235 moves upwards. Therefore, the limiting plate 204 and the push plate 227 are automatically reset. Then, the moving frame 302 can be smoothly moved to the upper side of the bearing plate 301, so as to adsorb the packaging bag on the bearing plate 301.
