Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foaming pre-packaging production, in particular to a novel foaming pre-packaging positioning mechanism. BACKGROUND

[0002] In the production process of foaming pre-packaging, the box body is usually made of galvanized steel plate. According to the product specification requirements, the wall thickness of the galvanized steel plate is generally controlled in the range of 0.5mm-1mm. In the continuous operation process of the production line, the foaming pre-packaging conveyed on the conveying belt needs to be transferred to the positioning mechanism to realize the precise docking of the subsequent process.

[0003] The specific implementation of the transfer positioning operation in the prior art is as follows: first, a cantilever side clamping manipulator is inserted from above the positioning mechanism, and the foaming pre-packaging is lifted by the side clamping structure of the manipulator; at this time, the width centering assembly arranged on the positioning mechanism is in an open state; then, the cantilever side clamping manipulator drives the foaming pre-packaging to descend synchronously until the foaming pre-packaging is stably placed on the cantilever bracket of the positioning mechanism; after the box body is positioned, the cantilever side clamping manipulator continues to move downward, so that the clamping jaw structure passes through the gap between the cantilever brackets and moves to the area below the positioning mechanism; finally, the two width centering assemblies of the positioning mechanism are synchronously moved inward to realize the centering positioning of the foaming pre-packaging in the width direction, and the length centering assembly of the positioning mechanism is also clamped inward to complete the centering positioning of the foaming pre-packaging in the length direction, thus completing the entire transfer positioning process.

[0004] However, the positioning process in the above-mentioned prior art has obvious defects: when the foaming pre-packaging is centered in the width direction and the length direction, the centering assemblies in the two directions operate independently, and there is a lack of effective linkage control mechanism between them, which is not conducive to the improvement of the continuous operation efficiency of the production line. SUMMARY

[0005] The purpose of the present application is to provide a novel foaming pre-packaging positioning mechanism to solve the above-mentioned deficiencies in the prior art.

[0011] When the driving member drives the first clamping member to move along the width direction of the foamed pre-pack, the transmission member simultaneously transmits the driving force of the driving member to the second clamping member, driving the second clamping member to generate a linear displacement along the length direction of the foamed pre-pack, so as to simultaneously realize the clamping of the foamed pre-pack by the second clamping member in the length direction of the foamed pre-pack.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Please see Figures 1-12 The present invention provides a novel foam pre-packaging positioning mechanism, comprising a frame 1, a cantilever bracket 4 mounted on the frame 1, and further comprising:

[0038] The first clamping member 3 is configured to clamp and position the foam pre-assembled box 7 along the width direction of the foam pre-assembled box 7.

[0039] The second clamping member 5 is disposed on the cantilever bracket 4, and the second clamping member 5 is configured to clamp and position the foam pre-pack 7 along the length direction of the foam pre-pack 7.

[0040] The driving component 2 is connected to the first clamping component 3 and is used to drive the first clamping component 3 to generate a linear displacement along the width direction of the foamed pre-packing box 7 so as to achieve clamping of the foamed pre-packing box 7 in the width direction through the displacement of the first clamping component 3.

[0041] The transmission component 6 is in transmission cooperation with the driving component 2 and the second clamping component 5 respectively, forming a power transmission path between the driving component 2 and the second clamping component 5;

[0042] When the driving member 2 drives the first clamping member 3 to move along the width direction of the foamed pre-packing box 7, the transmission member 6 simultaneously transmits the driving force of the driving member 2 to the second clamping member 5, driving the second clamping member 5 to generate linear displacement along the length direction of the foamed pre-packing box 7, so as to simultaneously realize the clamping of the foamed pre-packing box 7 by the second clamping member 5 in the length direction.

[0043] During implementation, the drive unit 2 is in a stopped state, the first clamping unit 3 is in the maximum open state along the width direction, and the spacing is greater than the width specification of the foam pre-pack 7. The second clamping unit 5 is also in the open state along the length direction, and the spacing is greater than the length specification of the foam pre-pack 7, to ensure that the pre-pack can be successfully placed.

[0044] The cantilever bracket 4 of the frame 1 remains horizontal and serves as a carrying platform for the foamed pre-packaged box 7. When the foamed pre-packaged box 7 on the production line conveyor belt is transferred to the positioning mechanism by the robot, the robot gripper drives the foamed pre-packaged box 7 to descend until the bottom surface of the pre-packaged box is stably attached to the support surface of the cantilever bracket 4. At this time, the pre-packaged box is in the initial central position to be positioned.

[0045] The driving component 2 serves as a power source, and its power output end is directly connected to the first clamping component 3. When the driving component 2 drives the first clamping component 3, the first clamping component 3 approaches both sides of the foam pre-packing box 7 in the width direction until the grippers adhere to the side wall of the foam pre-packing box 7 and apply a stable clamping force to complete the positioning of the foam pre-packing box 7 in the width direction.

[0046] Through the transmission component 6, the second clamping component 5 synchronously obtains the power of the driving component 2, directs the power and transmits it to the second clamping component 5. The second clamping component 5 synchronously approaches the two end walls of the foam pre-pack 7 in the length direction, and finally achieves the positioning of the foam pre-pack 7 in the length direction. In the whole process, there is no time difference between the clamping actions in the width and length directions, and they are started synchronously to quickly complete the positioning.

[0047] In this embodiment, the driving component 2 is used as the power core and the transmission component 6 is used to complete the centering and clamping in the length direction. The positioning action that originally required two independent driving sources can be completed synchronously with one drive. This eliminates the time difference of bidirectional positioning in the prior art, improves the efficiency of the production line, and simplifies the power and control structure.

[0048] In an embodiment of the present invention, the driving component 2 includes a power wheel 21, a power belt 22 and a power source. A pair of power wheels 21 are fixedly installed at both ends of the frame 1 and are connected by the power belt 22. The power source is used to drive the power belt 22 to rotate.

[0049] The power source is a linear cylinder, and the output end of the linear cylinder is fixedly connected to the power belt 22.

[0050] A pair of drive pulleys 21 are synchronous belt pulleys, with their grooves adapted to the drive belt 22. They are fixedly mounted on the top of the frame 1 via bearing seats and at both ends along the width direction of the foam pre-pack 7. The cylinder body is horizontally fixed to the side of the frame 1 via a bracket. The output shaft axis of the cylinder is consistent with the transmission direction of the drive belt 22, i.e., the width direction of the foam pre-pack 7. The cylinder is not shown in the attached drawing. During operation, after receiving the control signal, the linear cylinder extends or retracts its output shaft along the width direction of the foam pre-pack 7. Since the drive belt 22 is wound between the pair of drive pulleys 21, the linear tension of the cylinder is converted into the cyclic rotation power of the drive belt 22, driving the two drive pulleys 21 to rotate synchronously.

[0051] The power source can be a servo motor, and the output end of the servo motor is connected to the power belt 22.

[0052] In an embodiment of the present invention, the first clamping member 3 includes a first track 31, a mounting platform 32, a first centering claw 33, and a connector 34. The first track 31 is arranged along the width direction of the foam pre-assembly box 7. A pair of mounting platforms 32 are respectively fixed on the slide of the first track 31. A pair of first centering claws 33 are respectively fixed on a pair of mounting platforms 32. The pair of mounting platforms 32 are respectively fixed to both sides of the power belt 22 by the connector 34, so as to realize the opposite displacement of the mounting platforms 32 by the opposite transmission of the power belt 22.

[0053] The connector 34 is used to realize the transmission connection between the mounting platform 32 and the power belt 22. Each set of mounting platforms 32 has a connector 34 welded to its side. The connector 34 is connected to the preset hole on the outer side wall of the power belt 22. In this way, a pair of mounting platforms 32 can be fixed on both sides of the power belt 22 respectively. That is, one set of mounting platforms 32 corresponds to the outer side of the upper half of the power belt 22, and the other set corresponds to the outer side of the lower half. This ensures that the power belt 22 can synchronously drive the mounting platforms 32 to move when it rotates. A fixed transmission relationship is established between the connector 34 and the pair of mounting platforms 32 of the first clamping member 3. By utilizing the symmetrical transmission characteristics of the power belt 22, the upper and lower halves move in opposite directions to realize the opposite or opposite displacement of the pair of mounting platforms 32. The mounting platforms 32 drive the first pair of centering claws 33 fixed on them to move synchronously towards each other to center and position the foam pre-packed box 7 in the width direction.

[0054] Please refer to the accompanying drawings for embodiments of the present invention. Figure 4 The transmission component 6 includes a transmission shaft 61, a driven wheel 62, and a belt linkage 63. The transmission shaft 61 is rotatably connected to the frame 1, and the driven wheel 62 is fixedly installed on the transmission shaft 61. The driven wheel 62 is connected to the power belt 22. The transmission shaft 61 and the second clamping component 5 are connected by the belt linkage 63.

[0055] The driven pulley 62 needs to be compatible with the power belt 22. When the power belt 22 rotates in a cycle as the linear cylinder of the drive component 2 extends and retracts, it will directly drive the driven pulley 62 to rotate synchronously, thereby driving the transmission shaft 61 to rotate coaxially with the driven pulley 62.

[0056] In the embodiments of the present invention, please refer to Figure 5 , Figure 6The second clamping member 5 includes a central column 51, a gear 52, a rack 53, a slide bar 54, a second guide rail 55, and a second pair of centering jaws 56. The central column 51 is rotatably connected to the cantilever bracket 4. The gear 52 is fixedly sleeved on the central column 51. The second guide rail 55 is installed in the cantilever bracket 4 and is arranged along the length direction of the foam pre-pack 7. A pair of second pair of centering jaws 56 are respectively fixedly installed on the slides at both ends of the second guide rail 55. The slide bar 54 is respectively fixedly installed on a pair of second pair of centering jaws 56. The rack 53 is detachably fixedly installed on a pair of slide bars 54. A pair of racks 53 are respectively meshed on opposite sides of the gear 52 so that the pair of racks 53 can move in opposite directions through the rotation of the gear 52.

[0057] During the alignment in the width direction, the belt linkage 63 of the transmission component 6 can provide power input to the second clamping component 5. The belt linkage 63 drives the central column 51 to rotate around its own axis. The gear 52 rotates synchronously with the central column 51. A pair of racks 53 are respectively meshed on opposite sides of the gear 52. During the alignment in the width direction, the gear 52 rotates, and the racks 53 distributed on both sides are displaced along the length direction of the foam pre-pack 7 by the meshing force. The second guide rail 55 is installed in the cantilever bracket 4 along the length direction. The slides at both ends of the second guide rail 55 are fixedly connected to the second alignment claw 56. The slide rod 54 is connected to the second alignment claw 56. In this way, the linear displacement of the racks 53 drives the second alignment claw 56 to move stably along the second guide rail 55 to achieve clamping in the length direction.

[0058] Compared to existing technologies where centering and clamping in the length and width directions are mostly driven independently and their actions are performed sequentially, this embodiment uses a single power source with no transmission delay, allowing centering and clamping to begin simultaneously in the length and width directions, significantly improving centering efficiency.

[0059] Traditional length-direction clamping is mostly driven by a single-sided cylinder, which pushes the box to the positioning block on the other side. This can easily lead to concentrated force on one side of the box, and thin steel plates are prone to dents. This invention uses a single cylinder to achieve centering action in four directions, avoiding deformation caused by force on one side and further reducing the scrap rate of the box.

[0060] In another embodiment of the present invention, a disconnection part is further included, which includes a sliding tooth 531, an elastic element 532, and a sliding post 533. A pair of sliding posts 533 are respectively fixedly installed at both ends of the rack 53. The sliding tooth 531 is slidably connected to the sliding post 533, and the elastic element 532 is sleeved on the sliding post 533.

[0061] The sliding tooth 531 has a first state and a second state. In the first state, the sliding tooth 531 is separated from the rack 53. In the second state, the sliding tooth 531 is pressed towards the rack 53 under the thrust of the gear 52, so that the elastic element 532 is compressed. The sliding tooth 531 is in contact with the end face of the rack 53. At this time, the distance between the top surfaces of adjacent teeth on the rack 53 is equal to the distance between the top surfaces of adjacent teeth on the rack 53 and the sliding tooth 531.

[0062] During the centering clamping process, the second pair of centering jaws 56 first completes the centering of the foamed pre-packed box 7 in the length direction. At this time, the first pair of centering jaws 33 has not yet completed the centering in the width direction. Therefore, the first pair of centering jaws 33 will continue to move. Due to the transmission action of the transmission component 6, the gear 52 continues to move. At this time, the rack 53 reaches its end. The gear 52 will then squeeze the sliding tooth 531, and the sliding tooth 531 will squeeze towards the position of the rack 53. At this time, the elastic element 532 is compressed to form the shape shown in the attached figure. Figure 8 In the state shown, gear 52 continues to rotate, and rack 53 and sliding teeth 531 move together to the position shown in the attached diagram. Figure 10 In the state shown, the rack 53 has no displacement space, and the side of the end sliding tooth 531 away from the rack 53 has no teeth. The gear 52 switches from meshing with the end sliding tooth 531 to free rotation, achieving automatic disengagement. This prevents the gear 52 from continuously rotating and causing excessive displacement of the rack 53, which would result in the second pair of centering claws 56 exerting additional pressure on the box. At this time, the second pair of centering claws 56 has just completed the centering and positioning of the foamed pre-packed box 7 in the length direction, but the centering in the width direction has not yet been completed. The gear 52 continues to rotate. In this way, while achieving simultaneous opening and positioning in the length and width directions, the gear 52 can automatically disengage after positioning in the width direction, avoiding interference. When resetting, the gear 52 rotates in the opposite direction. At this time, the sliding tooth 531 resets under the elastic force of the elastic element 532. During the reset, it is limited by the sliding post 533, forming the shape shown in the attached figure. Figure 12 In the state shown, the sliding tooth 531 and the gear 52 are engaged. When the gear 52 reverses, it can first drive the sliding tooth 531 to move. Due to the limiting effect of the sliding post 533, when the sliding tooth 531 continues to reset, it will inevitably drive the rack 53 to reset synchronously. In this way, the teeth of the rack 53 will re-engage with the gear 52 to achieve the smooth reset of the second pair of centering claws 56. No additional power is required throughout the process. The synchronous reset of the rack 53 and the sliding tooth 531 is achieved only through the reset force of the elastic element 532 and the reverse transmission of the gear 52. A pin is set on the sliding post 533 to ensure that the sliding tooth 531 can only move laterally.

[0063] The core innovation of this embodiment lies in the design of sliding teeth 531 at both ends, which solves the problem of termination when the centering is not synchronized in the length and width directions, prevents interference in the length and width directions, and ensures the reliability of reset at the same time.

[0064] Furthermore, the sliding pins 533 at both ends allow the effective transmission length of the rack 53 to be flexibly adjusted by the compression of the elastic element 532, thereby compensating for a certain length deviation.

[0065] In this embodiment, the galvanized steel sheet processing on the production line generates metal dust. During the alignment process, the gear 52 will have a dynamic interaction while idling. After the second alignment claw 56 completes the alignment in the length direction, the gear 52 enters the idling state. At this time, the end sliding tooth 531, under the restoring force of the elastic element 532, always tends to displace away from the rack 53. Its tooth side continuously maintains a dynamic interaction state of contact and disengagement with the teeth of the gear 52. Meanwhile, the gear 52 continues to rotate due to the drive of the transmission element 6. For each tooth pitch rotated, the tooth surface of the end sliding tooth 531 will first contact the current tooth of the gear 52. When the tooth sides of the gear 52 continue to rotate and the current tooth disengages, the elastic element 532 quickly rebounds, pushing the sliding tooth 531 to move towards the gear 52 and making a slight elastic collision with the next tooth of the gear 52. The gap between the teeth of the gear 52, the gap between the tooth root and the tooth tip, is the area where metal dust is most likely to accumulate. The elastic collision between the sliding tooth 531 and the teeth of the gear 52 will generate a small vibration, causing the dust particles in the gap between the teeth to be subjected to continuous vibration. The adhesion between the dust particles and the tooth surface is destroyed under the action of vibration, so as to achieve the self-cleaning effect of the gear 52.

[0066] In another embodiment of the present invention, a fixing block 534 is further included. The fixing block 534 is fixedly installed on both sides of the rack 53. The fixing block 534 is slidably sleeved on the outside of the slide rod 54. Bolts are provided on the fixing block 534.

[0067] After centering and unfolding, the transmission of the belt linkage 63 is released. By loosening the bolts on the fixing block 534, the rack 53 can slide on the slide rod 54. In this way, the initial meshing point of the rack 53 and the gear 52 can be changed. Thus, the initial distance between the sliding tooth 531 and the gear 52 can be adjusted. Therefore, the usable length of the rack 53 can be adjusted, that is, the depth can be matched according to the different lengths of the foam pre-packed box 7, so as to avoid the phenomenon of insufficient centering.

[0068] In this embodiment, there is no need to disassemble core components such as rack 53 and gear 52. Adjustment can be completed in just three steps: loosening bolts, sliding and tightening bolts, greatly shortening the single-specification switching time. Furthermore, it automatically adapts; after adjusting the usable length of rack 53, no adjustment of the disconnected section is required. Its emergency adaptability is strong. When a sudden non-standard length pre-packing box appears on the production line, this embodiment can complete the emergency adaptation in a short time through the sliding adjustment of rack 53, ensuring continuous operation of the production line.

[0069] In embodiments of the present invention, a stabilizing block 57 is included, and a slide bar 54 mounted on the same second pair of centering claws 56 is fixedly connected to the stabilizing block 57.

[0070] The stabilizing block 57 is slidably sleeved onto the ends of the two slide rods 54 through the positioning hole, and then fixed to the slide rods 54 by bolts. That is, the stabilizing block 57 spans the two slide rods 54. If the stabilizing block 57 obstructs the adjustment of the rack 53, the position of the stabilizing block 57 can be adjusted.

[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
