Description

Technical Field

[0001] This invention relates to the field of packaging box paper conveying equipment, and more particularly to a belt baffle correction conveyor. Background Technology

[0002] As people's living standards improve, they not only have higher and higher requirements for the products themselves, but also for the product packaging.

[0003] The product packaging boxes, once unfolded, are made of paper with a certain degree of rigidity. During processing, the paper may experience path deviations, primarily due to two reasons: First, when the paper enters the conveyor belt of the current station from the previous station, there is a speed difference between the two conveyor belts. The speed of the current station's conveyor belt is greater than that of the previous station's conveyor belt. This is equivalent to pulling the paper from the previous station's conveyor belt to the current station's conveyor belt, causing the paper to shift. Second, the equipment needs to transfer an adhesive layer onto the paper. During the transfer process, the adhesion of the adhesive also causes paper shifts. Currently, the paper deviations are mainly corrected in the left and right directions, but there is no targeted correction in the front-to-back direction of the paper. This causes the paper's path to deviate along the conveyor belt's transport direction. Once the paper's path deviates in the front-to-back direction, it cannot be aligned with the next production cycle. The production cycle corresponds to the path of the subsequent station; misalignment leads to processing errors and fails to meet current production requirements.

[0004] To solve the above problems, it is necessary to provide a belt baffle correction conveyor. Summary of the Invention

[0005] The purpose of this invention is to provide a belt baffle correction conveyor with a simple structure that can correct the workpiece along the conveying direction to improve processing accuracy.

[0006] To achieve the above objectives, the belt baffle correction conveyor provided by the present invention includes a bottom suction conveying device, a frame, and a correction wheel assembly. The frame is mounted above the bottom suction conveying device. The correction wheel assembly includes a transmission drive mechanism and a blocking block. The transmission drive mechanism is mounted on the frame, and the blocking block is mounted at the output end of the transmission drive mechanism. The blocking block has a blocking transmission path that blocks the workpiece and a bypass transmission path that avoids the workpiece through transmission. When the blocking block is in the blocking transmission path, the transmission path of the blocking block is above the transmission path of the bottom suction conveying device, and the two are parallel to each other. The transmission direction of the blocking block is the same as the transmission direction of the bottom suction conveying device, and the transmission speed of the blocking block is lower than the transmission speed of the bottom suction conveying device, so that the workpiece on the bottom suction conveying device is corrected in position by the blocking of the blocking block. When the blocking block is in the bypass transmission path, the blocking block, after being corrected in position, is released from obstruction and is conveyed forward with the bottom suction conveying device.

[0007] Preferably, the correction wheel assembly is provided in two sets, and the two correction wheel assemblies are arranged at intervals along the left and right directions of the frame.

[0008] Preferably, the transmission drive mechanism includes a drive device, a transmission component, a drive wheel, and a guide wheel assembly. The drive device is mounted on the frame, the drive wheel is mounted on the output end of the drive device, the guide wheel assembly is located above the bottom suction conveying device, and the transmission component is wound between the drive wheel and the guide wheel assembly, such that the transmission component forms a conveying section and a winding section parallel to the bottom suction conveying device.

[0009] Preferably, the transmission drive mechanism is mounted on the frame in an adjustable position.

[0010] Specifically, the transmission drive mechanism includes an X-axis moving device, a first moving component, a Y-axis moving device, a second moving component, a Z-axis moving device, a third moving component, a drive device, a transmission component, a drive wheel, and a guide wheel assembly. The X-axis moving device is mounted on the frame. The first moving component is mounted on the output end of the X-axis moving device and moves along the X-axis direction of the frame under its drive. The Y-axis moving device is mounted on the first moving component. The second moving component is mounted on the output end of the Y-axis moving device and moves along the Y-axis direction of the frame under its drive. The Z-axis moving device is mounted on the first moving component. The second moving member is mounted on the third moving member, which is mounted on the output end of the Z-axis moving device and moves along the Z-axis direction of the frame under its drive. The driving device is mounted on the second moving member, and the drive wheel is rotatably mounted on the second moving member. The drive wheel is mounted on the output end of the driving device and rotates under the drive of the driving device. The guide wheel group is located above the bottom suction conveying device. The transmission member is wound between the drive wheel and the guide wheel group, so that the transmission member forms a conveying section and a winding section parallel to the bottom suction conveying device.

[0011] Preferably, the frame is a gantry structure, the two ends of the first moving member are movably connected to the crossbar of the gantry structure through a first guide assembly, the second moving member is movably connected to the first moving member through a second guide assembly, and the third moving member is movably connected to the second moving member through a third guide assembly.

[0012] Specifically, the second moving component is an inverted T-shaped block structure, the third moving component is a long strip-shaped block structure arranged along the Z-axis of the frame, the guide wheel group includes a first guide wheel, a second guide wheel, a third guide wheel and a fourth guide wheel, the drive wheel is installed on the upper part of the second moving component, the first guide wheel and the second guide wheel are symmetrically arranged on both sides of the lower part of the second moving component, the third guide wheel and the fourth guide wheel are symmetrically arranged on both sides of the third moving component, and the transmission component is wound around the drive wheel, the first guide wheel, the second guide wheel, the third guide wheel and the fourth guide wheel.

[0013] Preferably, the bottom suction conveying device is a negative pressure suction conveying device, and the conveyor belt of the negative pressure suction conveying device is provided with multiple negative pressure suction holes at equal intervals.

[0014] Specifically, the first guide component, the second guide component, and the third guide component are all slide rail slider guide components.

[0015] Compared with the prior art, the belt baffle correction conveyor provided by the present invention combines a bottom suction conveyor and a correction wheel assembly. The blocking block of the correction wheel assembly has a blocking transmission path that blocks the workpiece and a avoiding transmission path that avoids the workpiece through transmission. When the blocking block is in the blocking transmission path, the transmission path of the blocking block is above the transmission path of the bottom suction conveyor and the two are parallel to each other. The transmission direction of the blocking block is the same as the transmission direction of the bottom suction conveyor, and the transmission speed of the blocking block is lower than the transmission speed of the bottom suction conveyor, so that the blocking block is positioned on the bottom suction conveyor. The workpiece is corrected in position by the blocking block. When the blocking block is in the position of avoiding the transmission path, the blocking block is released after the position is corrected and is conveyed forward by the bottom suction conveyor. In other words, when the workpiece with a position deviation moves towards the blocking block under the conveying of the bottom suction conveyor, the blocking block also moves forward and blocks in front of the workpiece. By using the fact that the speed of the blocking block is lower than the speed of the bottom suction conveyor, the workpiece is adjusted in position by the blocking block. After the adjustment is completed, the blocking block quickly switches from blocking the transmission path to avoiding the transmission path. The blocking block with the position adjusted moves forward with the bottom suction conveyor. Attached Figure Description

[0021] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please see Figures 1 to 5The belt baffle-type conveyor 100 of the present invention includes a bottom suction conveying device 1, a frame 2, and a correction wheel assembly 3. The frame 2 is mounted above the bottom suction conveying device 1. The correction wheel assembly 3 includes a transmission drive mechanism 31 and a blocking block 33. The transmission drive mechanism 31 is mounted on the frame 2, and the blocking block 33 is mounted on the output end of the transmission drive mechanism 31. The blocking block 33 has a blocking transmission path that blocks the workpiece and a avoiding transmission path that avoids the workpiece through transmission. The blocking block 33 switches between the blocking transmission path and the avoiding transmission path. When the blocking block 33 is in the blocking transmission path, the transmission path of the blocking block 33 is above the transmission path of the bottom suction conveying device 1 and the two are parallel to each other. The transmission direction of the blocking block 33 is the same as the transmission direction of the bottom suction conveying device 1. The transmission speed of the blocking block 33 is... The transmission speed is lower than that of the bottom suction conveyor 1, so that the workpiece on the bottom suction conveyor 1 is corrected in position by the blocking block 33. When the blocking block 33 is in the position of avoiding the transmission path, the blocking block 33 after the position is corrected is released and conveyed forward with the bottom suction conveyor 1. In other words, when the workpiece with a position deviation moves towards the blocking block 33 under the conveying of the bottom suction conveyor 1, the blocking block 33 also moves forward and blocks in front of the workpiece. By using the fact that the speed of the blocking block 33 is lower than that of the bottom suction conveyor 1, the workpiece is adjusted in position by the blocking block 33. When the adjustment is completed, the blocking block 33 quickly switches from blocking the transmission path to avoiding the transmission path. The blocking block 33 is just in the turning position and avoids the blocking block 33. The blocking block 33 after the position adjustment is completed moves forward with the bottom suction conveyor 1. It is understandable that the transmission drive mechanism 31 can also be configured with variable speed. Utilizing the fact that the speed of the blocking block 33 is lower than the speed of the bottom suction conveyor 1, the workpiece adjusts its position under the obstruction of the blocking block 33. Once the adjustment is complete, the blocking block 33 accelerates to the speed of the bottom suction conveyor 1 and gradually increases its speed to exceed that of the bottom suction conveyor 1. The workpiece is accelerated by the blocking block 33 until it synchronizes with the bottom suction conveyor 1, and finally, through overspeed, it is thrown away, thus achieving the transition process. The blocking block 33, having completed its position adjustment, moves forward along with the bottom suction conveyor 1. More specifically, as follows: Please see Figures 1 to 2 The correction wheel assembly 3 has two sets, which are spaced apart along the left and right sides of the frame 2. It can be understood that the packaging box is formed by folding paper. In this way, the packaging box is not a regular piece of paper. During the conveying process, the two starting ends of the paper are in different positions. The two sets of correction wheel assemblies 3 are for corresponding to the different starting ends on both sides. One set of correction wheel assemblies 3 is prone to errors due to paper offset. The two sets can correct the paper evenly from both sides, reducing errors and improving the accuracy of position correction.

[0023] Please see Figures 1 to 3 In other embodiments, when the transmission segment 3181 of the transmission member 318 is fixed, the transmission drive mechanism 31 includes a drive device 317, a transmission member 318, a drive wheel 319, and a guide wheel assembly 320. The drive device 317 is mounted on the frame 2, the drive wheel 319 is mounted on the output end of the drive device 317, and the guide wheel assembly 320 is located above the bottom suction conveying device 1. The transmission member 318 is wound between the drive wheel 319 and the guide wheel assembly 320, so that the transmission member 318 forms a transmission segment 3181 and a winding segment 3182 parallel to the bottom suction conveying device 1. For details, please refer to [link to relevant documentation]. Figure 3 The transmission segment 3181 and the winding segment 3182.

[0024] Please see Figures 3 to 5 In this embodiment, the transmission drive mechanism 31 is mounted on the frame 2 in an adjustable position, thereby driving the transmission section 3181 of the transmission component 318 to move along the X-axis, Y-axis and Z-axis directions of the frame 2. When the transmission section 3181 of the transmission component 318 is in a movable configuration, the transmission drive mechanism 31 includes an X-axis moving device 311, a first moving component 312, a Y-axis moving device 313, a second moving component 314, a Z-axis moving device 315, a third moving component 316, a drive device 317, a transmission component 318, a drive wheel 319, and a guide wheel assembly 320. The X-axis moving device 311 is mounted on the frame 2, and the first moving component 312 is mounted on the output end of the X-axis moving device 311. The first moving component 312 moves along the X-axis direction of the frame 2 under the drive of the X-axis moving device 311. The Y-axis moving device 313 is mounted on the first moving component 312, and the second moving component 314 is mounted on the output end of the Y-axis moving device 313. The second moving component 314 moves under the drive of the Y-axis moving device 313. The device moves along the Y-axis of the frame 2. The Z-axis moving device 315 is installed on the second moving member 314, and the third moving member 316 is installed on the output end of the Z-axis moving device 315. The third moving member 316 moves along the Z-axis of the frame 2 under the drive of the Z-axis moving device 315. The driving device 317 is installed on the second moving member 314, and the driving wheel 319 is rotatably installed on the second moving member 314. The driving wheel 319 is installed on the output end of the driving device 317 and rotates under the drive of the driving device 317. The guide wheel group 320 is located above the bottom suction conveying device 1. The transmission member 318 is wound between the driving wheel 319 and the guide wheel group 320, so that the transmission member 318 forms a transmission section 3181 and a winding section 3182 parallel to the bottom suction conveying device 1.

[0025] Please see Figures 1 to 5The frame 2 is a gantry structure, which includes vertical rods 21 located on both sides of the bottom suction conveyor 1 and horizontal rods 22 located between the two vertical rods. Two horizontal rods 22 are provided, parallel and spaced apart between the two vertical rods 21. The two ends of the first moving member 312 are movably connected to the horizontal rods of the gantry structure via a first guide assembly 321. The second moving member 314 is movably connected to the first moving member 312 via a second guide assembly 322. The third moving member 316 is movably connected to the second moving member 314 via a third guide assembly 323. For example, the first guide assembly 321, the second guide assembly 322, and the third guide assembly 323 are all slide rail slider guide assemblies, but are not limited to this.

[0026] Please see Figure 3 and Figure 5 The second moving part 314 is an inverted T-shaped block structure, and the third moving part 316 is a long strip block structure arranged along the Z-axis direction of the frame 2. The guide wheel group 320 includes a first guide wheel 3201, a second guide wheel 3202, a third guide wheel 3203, and a fourth guide wheel 3204. The drive wheel 319 is rotatably mounted on the upper part of the second moving part 314 via a rotating shaft. The first guide wheel 3201 and the second guide wheel 3202 are symmetrically arranged on both sides of the lower part of the second moving part 314. The first guide wheel 3201 and the second guide wheel 3202 are both rotatably connected to the second moving part 314. The third guide wheel 3203 and the fourth guide wheel 3204 are symmetrically arranged on both sides of the third moving part 316. The transmission part 318 is wound around the drive wheel 319, the first guide wheel 3201, the second guide wheel 3202, the third guide wheel 3203, and the fourth guide wheel 3204.

[0027] Please see Figures 1 to 2 The bottom suction conveyor 1 is a negative pressure suction conveyor. The conveyor belt of the negative pressure suction conveyor is provided with multiple negative pressure suction holes 11 at equal intervals, which effectively reduces friction during paper conveying and improves conveying accuracy.

[0028] Please refer to the following: Figures 1 to 5 The working process of the belt baffle correction conveyor 100 of the present invention is as follows: When a workpiece with a positional deviation is conveyed by the bottom suction conveyor 1, it moves towards the blocking blocks 33 on both sides. At this time, the blocking blocks 33 also move forward and block the front of the workpiece. By utilizing the fact that the speed of the blocking blocks 33 is lower than the speed of the bottom suction conveyor 1, the workpiece adjusts its position under the obstruction of the blocking blocks 33. After the adjustment is completed, the blocking blocks 33 quickly switch from blocking the transmission path to avoiding the transmission path. The blocking blocks 33, whose position has been adjusted, move forward with the bottom suction conveyor 1.

[0029] By combining the bottom suction conveyor 1 and the correction wheel assembly 3, the blocking block 33 of the correction wheel assembly 3 has a blocking transmission path that blocks the workpiece and a avoiding transmission path that avoids the workpiece through transmission. When the blocking block 33 is in the blocking transmission path, the transmission path of the blocking block 33 is above the transmission path of the bottom suction conveyor 1 and the two are parallel to each other. The transmission direction of the blocking block 33 is the same as the transmission direction of the bottom suction conveyor 1, and the transmission speed of the blocking block 33 is lower than the transmission speed of the bottom suction conveyor 1, so that the workpiece on the bottom suction conveyor 1 is corrected by the blocking block 33. When the blocking block 33 is in the correct position and is avoiding the transmission path, the blocking block 33, after being corrected in position, is released from obstruction and is conveyed forward with the bottom suction conveyor 1. In other words, when a workpiece with a positional deviation moves closer to the blocking block 33 under the conveying of the bottom suction conveyor 1, the blocking block 33 also moves forward and blocks in front of the workpiece. By utilizing the fact that the speed of the blocking block 33 is lower than the speed of the bottom suction conveyor 1, the workpiece adjusts its position under the obstruction of the blocking block 33. After the adjustment is completed, the blocking block 33 quickly switches from blocking the transmission path to avoiding the transmission path. The blocking block 33, after the position adjustment is completed, moves forward with the bottom suction conveyor 1.
