Description

Technical Field

[0001] The present invention relates to the technical field of box packaging transfer and transportation, and particularly to a steering and positioning device for a box packaging transportation track. Background Art

[0002] A steering and positioning device for a box packaging transportation track is a steering control device used to connect upstream and downstream conveyor lines. It can adjust the angle and calibrate the direction of the boxes from the upstream transportation track, and then accurately introduce them onto the downstream conveyor lines in different directions. It can change the orientation and movement path of the boxes according to process requirements, improve the automation level and multi-path processing ability of the packaging process, and is applicable to multi-process and multi-direction logistics transportation scenarios.

[0003] In the prior art, a steering and positioning device for a box packaging transportation track generally captures the boxes using a clamping and transportation structure, and then flips and turns them to send them onto the downstream conveyor lines in different directions. However, the clamping and transportation structure lacks a structure for detecting the clamping state. The boxes may not be correctly clamped by the clamping and transportation structure, not accurately clamped or clamped off to one side. When the device starts flipping or turning operations, the boxes may become loose, shift, or even fall off, which not only affects the conveying accuracy, but may also cause damage to the boxes or jam the operation of the device, resulting in the interruption of the entire conveying system. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, a steering and positioning device for a box packaging transportation track generally captures the boxes using a clamping and transportation structure, and then flips and turns them to send them onto the downstream conveyor lines in different directions. However, the clamping and transportation structure lacks a structure for detecting the clamping state. The boxes may not be correctly clamped by the clamping and transportation structure, not accurately clamped or clamped off to one side. When the device starts flipping or turning operations, the boxes may become loose, shift, or even fall off, which not only affects the conveying accuracy, but may also cause damage to the boxes or jam the operation of the device, resulting in the interruption of the entire conveying system. Therefore, a steering and positioning device for a box packaging transportation track is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

A vertical groove is formed on the side of the terminal folding seat. A transportation clamping assembly for transferring the packaging boxes conveyed by the previous transportation track to the next transportation track is arranged below the terminal folding seat. A steering assembly for front-side turning or left-right turning of the packaging boxes on the transportation clamping assembly is arranged on the top of the terminal folding seat. The transportation clamping assembly includes a mounting plate, a capture motor, a bidirectional screw, and a mounting plate. The output end of the capture motor is fixedly provided with a bidirectional screw, and docking frames are symmetrically screwed onto the outer wall of the bidirectional screw. There are two mounting plates in total. Conveyor belts are symmetrically arranged at the top edges of the two mounting plates. A clamping state detection mechanism for detecting whether the transportation clamping assembly completely and parallelly clamps the side wall of the packaging box is arranged at the middle position of the mounting plate.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention is provided with two mounting plates. The sides of the two mounting plates form a transportation clamping assembly for the packaging box through a bidirectional screw. A clamping state detection mechanism is arranged at the middle position of the mounting plate. After the transportation clamping assembly obtains the packaging box from the upstream transportation line, the clamping state detection mechanism is used to sense whether the packaging box is clamped flat and accurately. The clamping state detection mechanism cooperates with the steering and positioning structure. Only when the clamping state detection mechanism senses that the packaging box is clamped flat and accurately, can the steering assembly act to turn the packaging box over and rotate it, avoiding the lack of a structure for detecting the clamping state on the clamping transportation structure. The packaging box may not be correctly clamped by the clamping transportation structure, not accurately clamped or clamped obliquely. When the equipment starts to perform flipping or steering operations, the packaging box may become loose, offset or even fall off, which not only affects the conveying accuracy but also may cause problems such as damage to the packaging box or jamming of the equipment operation.

[0018] 2. The present valve is provided with a quick re-clamping assembly and a clamping state detection mechanism at the ends of the two mounting plates. The clamping detection mechanism is entirely composed of a plurality of conductive metal columns, greatly reducing the load and control difficulty of the controller. The signal triggering is simple and reliable, greatly reducing the processing logic and hardware burden of the controller, and improving the system stability and fault controllability. When the clamping state detection mechanism senses that the packaging box may not be correctly clamped by the clamping transportation structure, not accurately clamped or clamped obliquely, the quick re-clamping assembly quickly releases the two clamping mounting plates on the premise that the screw-like structure for driving the two clamping plates remains stationary, and then makes the clamping mounting plates reset again to re-clamp the packaging box. It can act independently without moving the main driving screw structure, realizing local quick release and re-clamping, with a fast response speed, not affecting the overall jaw positioning structure, and ensuring continuous operation without interruption.

[0019] 3. The present invention is provided with a secondary re-clamping driving assembly near the quick re-clamping assembly. The power source of the secondary re-clamping driving assembly will extend regardless of the clamping state of the packaging box sensed by the clamping state detection mechanism, without the need for the controller to control through a complex control program, realizing the functional advantages of mechanical self-judgment and action isolation. Whether the clamping structure successfully clamps the packaging box or not, this assembly will act, but only when the clamping is abnormal, it will trigger secondary re-clamping through pure mechanical linkage, without the need for the controller to participate in judgment and control, greatly reducing the system's dependence on electronic control and improving the fault tolerance and reliability in cases such as power failure, interference or abnormal control systems. At the same time, when the clamping is correctly completed, although the assembly acts, it will not affect the jaw state, realizing the intelligent isolation of the action signal and jaw linkage, avoiding unnecessary repeated clamping, and reducing mechanical damage to the packaging box and jaw wear.

The steering component includes a left and right flipping motor 6, a folding seat 5, a bottom folding seat 3 and a compensation seat 1. The compensation seat 1 raises the height of the entire device to match the actual height of the packaging box transport track.

[0036] A bottom motor 2 is fixedly arranged at the bottom of the compensation seat 1, a bottom folding seat 3 is fixedly arranged at the output end of the bottom motor 2, a front-and-rear flipping motor 4 is fixedly arranged at the side of the bottom folding seat 3, a folding seat 5 is fixedly arranged at the output end of the front-and-rear flipping motor 4, a left-and-right flipping motor 6 is fixedly arranged at the top of the folding seat 5, a terminal folding seat 61 is fixedly arranged at the output end of the left-and-right flipping motor 6, the left-and-right flipping motor 6 and the front-and-rear flipping motor 4 can drive the packaging box to turn, and adjust the required plane of the packaging box to the required position.

[0037] The transport clamping assembly includes a mounting plate 13, a capture motor 7, a bidirectional screw 9, and a mounting plate 13. A bidirectional screw 9 is fixedly arranged at the output end of the capture motor 7. A docking frame 29 is symmetrically threaded into the outer wall of the bidirectional screw 9. The housing of the capture motor 7 is fixedly arranged on the top of the edge block 8. The side of the edge block 8 is fixedly connected to the side of the end folding seat 61. The docking frame 29 extends into the interior of the vertical groove 610. The outer wall of the bidirectional screw 9 is symmetrically arranged with external threads of opposite rotation directions. There are two mounting plates 13 in total. Conveyor belts 14 are symmetrically arranged at the top edge positions of the two mounting plates 13. The specific structure of the conveyor belt 14 is two pulleys. The outer walls of the two pulleys are covered with the same conveyor belt. A motor is arranged on a pulley shaft. Since the conveyor belt 14 is a mature technology in the prior art, it is not disclosed in this application document.

[0038] A clamping state detection mechanism for detecting whether the transportation clamping assembly completely and parallelly clamps the side wall of the packaging box is arranged at the middle position of the mounting plate 13. The clamping state detection mechanism includes an intermediate box 23, a T-shaped block 24, and a metal guide post 26. An intermediate groove 18 is formed at the middle position of the top of the mounting plate 13, and the intermediate box 23 is fixedly arranged inside the intermediate groove 18. An installation groove 231 is formed at the top of the intermediate box 23.

[0039] T-shaped blocks 24 are fixedly arranged at equal intervals inside the installation groove 231. The T-shaped block 24 has a structure that is wider at the top and narrower at the bottom. A metal guide post 26 is inserted into the gap between adjacent T-shaped blocks 24 in the installation groove 231. Current transformers 25 are screwed into the tops of the T-shaped blocks 24 at the top edge of the installation groove 231. The two current transformers 25 are connected in series to the positive wire of the front and rear flipping motor 4 through wires. One end of the side wall of the metal guide post 26 is fixedly connected to one end of an extension block 27. One end of a light spring 28 is fixedly connected to the bottom of the extension block 27, and the other end of the light spring 28 is fixedly connected to the top of the installation groove 231. When the light spring 28 is in its original length, the metal guide post 26 will protrude from one side of the mounting plate 13, and at this time, the outer wall of the metal guide post 26 will not contact the adjacent T-shaped block 24.

[0040] An intermediate block 16 is fixedly arranged at the middle position of the side of the mounting plate 13. The intermediate block 16 is inserted into the side of the docking frame 29 movably. One end of a connecting spring 30 is fixedly connected to the side of the intermediate block 16, and the other end of the connecting spring 30 is fixedly connected to the side of a vertical T-shaped block 31. The vertical T-shaped block 31 is inserted into a vertical T-shaped groove 32 movably. The vertical T-shaped groove 32 is formed on the side of an edge cover 33. The edge cover 33 is fixedly connected to the side of the docking frame 29 by bolts. The setting of the T-shaped block 31 and the edge cover 33 enables the connecting spring 30 to always follow the intermediate block 16 no matter where the intermediate block 16 is driven by the docking frame 29 when the intermediate block 16 moves along the vertical plane.

[0041] A quick re-clamping assembly for driving the transportation clamping assembly to re-clamp the packaging box twice when the clamping state of the packaging box is abnormal is arranged inside the docking frame 29. The quick re-clamping assembly includes a guide post 161, a transverse movement seat 20, a vertical T-shaped block 31, and a secondary re-clamping driving assembly. The secondary re-clamping driving assembly can select whether to control the action of the quick re-clamping assembly according to the clamping state of the packaging box. The secondary re-clamping driving assembly includes an electromagnet 19, a pull rod 191, an action cylinder 21, and a hook-shaped rod 15.

[0042] A hook-shaped rod 15 is fixedly arranged at the side edge position of the mounting plate 13. The actuating cylinder 21 is fixedly connected to the side of the mounting seat 22. The side of the mounting seat 22 is fixedly connected to the side of the end folding seat 61. A transverse moving seat 20 is fixedly arranged at the output end of the actuating cylinder 21. An electromagnet 19 is fixedly arranged on the side of the transverse moving seat 20. The tops of two T-shaped blocks 24 arranged at the top edge position of the mounting groove 231 are connected in series to the power supply wire of the electromagnet 19 through wires. A pulling rod 191 is vertically fixedly arranged at the output end of the electromagnet 19. Both ends of the pulling rod 191 extend into the head of the configuration rod 15.

[0043] On the front side of the docking frame 29, a bottom horizontal groove 291, an inclined groove 292, and a top horizontal groove 293 are sequentially opened. A guide post 161 is fixedly arranged on the front side of the intermediate block 16. The guide post 161 is movably inserted into the bottom horizontal groove 291 or the inclined groove 292 or the top horizontal groove 293. The inner cavity height of the docking frame 29 is higher than the height of the intermediate block 16. A path limiting component is arranged at the side edge position of the mounting plate 13. When the secondary re-clamping driving component pushes the quick re-clamping driving component to act, the mounting plate 13 can only move horizontally along a two-dimensional plane. The path limiting component includes a vertical guide rail 10, a transverse moving block 11, and a vertical T-shaped rod 17. The vertical T-shaped rod 17 is fixedly arranged on the side of the mounting plate 13. The vertical T-shaped rod 17 is movably inserted into the transverse moving block 11 along the horizontal direction. A T-shaped groove 12 is opened at the corresponding position of the transverse moving block 11. The transverse moving block 11 is movably inserted onto the vertical guide rail 10 along the vertical direction. The vertical guide rail 10 is fixedly connected to the side of the end folding seat 61.

[0044] The specific implementation steps and principles of the present invention are as follows: Under the action of the light spring 28, multiple conductive metal columns 26 do not enter between adjacent T-shaped blocks 24. At this time, the electromagnet 19 and the front and rear flipping motors 4 are not powered on. At this time, the electromagnet 10 does not extend out, and multiple conductive metal columns 26 all maintain the extended state.

[0045] When the packaging box is transported by the upstream conveyor line and is sent onto the conveyor belt 14 on the two mounting plates 13, since the connecting spring 30 is in the original length at this time and the guide post 161 is inside the bottom horizontal groove 291, the capture motor 7 drives the bidirectional screw 9 to rotate, which will drive the two mounting plates 13 to approach normally. When the packaging box is in place and clamped normally, all the conductive metal columns 26 will enter between adjacent T-shaped blocks 24. At this time, the front and rear flipping motors 4 and the electromagnet 19 are powered on. The output end of the electromagnet 19 extends out, and the pulling rod 191 disengages from the head of the configuration rod 15. At this time, even if it retracts, it will not drive the two mounting plates 14 to move horizontally through the pulling rod 191. The front and rear flipping motors 4 normally drive the packaging box to turn and flip to the specified downstream conveyor line position.

[0046] When the packaging box is clamped normally and not in place, only part of the conductive metal column 26 enters between the adjacent T-shaped blocks 24. At this time, the electromagnet 19 and the front and rear flipping motors 4 are not powered on. The controller normally controls the action cylinder 21 to cycle once, retract and then extend. At this time, the output end of the electromagnet 19 will not extend, and the pulling rod 191 does not disengage from the head of the configuration rod 15. The pulling rod 191 pulls the mounting plate 13 to move horizontally through the configuration rod 15. At this time, the guide post 161 moves from the bottom horizontal groove 291, the inclined groove 292, and the top horizontal groove 293. The two mounting plates 13 move away quickly. When the action cylinder 21 extends, under the reset of the connecting spring 30, the two mounting plates 13 quickly re-clamp the packaging box.

[0047] It should be added that the controller of the entire device is set on the side of the housing of the front and rear flipping motors 4. The controller can select a PLC controller in the prior art. When the current transformer 26 does not sense the passing of current for a long time, the controller can repeatedly control the action cylinder 21 to extend and retract, and repeat the clamping of the packaging box through the above mechanism.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
