Description

Technical Field

[0001] The invention relates to the technical field of bottle clamping conveyors, in particular to a bottle clamping conveyor with stable clamping. Background Art

[0002] A bottle-gripping conveyor is a device designed to stably transport bottles along a production line. It is commonly used in filling lines in the beverage, food, and pharmaceutical industries to ensure bottles remain upright and stable during transport, facilitating subsequent operations such as washing, filling, and capping.

[0003] The patent with the current announcement number CN212711092U discloses a bottle clamping conveyor, which includes a frame with two parallel S-shaped conveyor belts vertically arranged on both sides of the frame. The belt surfaces of the S-shaped conveyor belts are arranged opposite each other, and the two ends of the S-shaped conveyor belts are kept horizontal. The lower end of the S-shaped conveyor belt is provided with a first horizontal conveyor belt, and the upper end is provided with a second horizontal conveyor belt. The belt surfaces of the two S-shaped conveyor belts are perpendicular to the first horizontal conveyor belt. The first and second horizontal conveyor belts extend below the ends of the two S-shaped conveyor belts. A plurality of clamping blocks are arrayed on the surface of the S-shaped conveyor belt, and the length direction of the clamping blocks is perpendicular to the movement direction of the S-shaped conveyor belt. The bottle clamping conveyor is convenient for conveying filled bottles and ensures that the filled bottles remain upright when conveyed to the downstairs process, which is convenient for processing in the next process. It has the advantage of improving production efficiency.

[0004] However, the above-mentioned bottle clamping conveyor still has the following problems in actual use: When conveying bottles from the same batch, a bottle clamping conveyor may need to adjust the distance between the two conveyor belts to accommodate a different bottle type due to a different bottle diameter. However, currently, changing the two conveyor belts often requires manual measurement of the bottle diameters and subsequent manual or motorized adjustment of the distance between the two belts. This method is not only cumbersome but also wastes time during testing, reducing conveying efficiency. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 7, a bottle-clamping conveyor with stable clamping comprises two clamping plates 3 installed on one side of a conveyor belt 1 and symmetrically arranged, a plurality of flexible rubber clamping belts rotating in a circular manner are provided on adjacent sides of the two clamping plates 3, and a bracket 2 is provided under the two clamping plates 3 at the same time, the upper end of the bracket 2 is fixedly connected to a support plate 6, and the end of the support plate 6 away from the conveyor belt 1 is fixedly connected to two auxiliary frames 4, and the interior of the support plate 6 is connected to a No. 1 self-adjusting mechanism, and the output end of the No. 1 self-adjusting mechanism is connected to the two clamping plates 3, and the end of the support plate 6 away from the auxiliary frame 4 is connected to an extension component, and the other end of the extension component is connected to the support component and the thickness monitoring mechanism, and the other end of the support component is connected to the No. 2 self-adjusting mechanism, and the output end of the No. 2 self-adjusting mechanism is connected to two moving components, and the lower ends of the two moving components are connected to auxiliary components, and the centers of the two auxiliary components are aligned with the centers of the two clamping plates 3.

[0021] The bottle clamping conveyor with stable clamping in the present invention is similar in structure to the existing bottle clamping conveyor, such as the bottle clamping conveyor disclosed in the patent publication number CN212711092U. Figures 1 to 7 As shown, when the bottle-holding conveyor with stable clamping of the present invention is in use, it is only necessary to ensure that the support plate 6 and the conveyor belt 1 are aligned before conveying (this can be achieved when the equipment is first installed). Then, each time the bottle is conveyed using the cyclically rotating flexible rubber clamping belt on the two clamping plates 3, when the bottle is about to move along the conveyor belt 1 to the position of the two clamping plates 3, the bottle will first pass through the thickness monitoring mechanism, and then the thickness monitoring mechanism will immediately measure the diameter of the bottle and immediately activate the first and second self-adjusting mechanisms via the external PLC controller; After the No. 1 self-adjusting mechanism is started, its output end will immediately carry the two clamping plates 3 to move toward the middle or both sides at the same time. When the two clamping plates 3 move, they will bring two groups of several circularly rotating flexible rubber clamping belts closer together, so that they can just fit the bottles that need to be transported. After the No. 2 self-adjusting mechanism is started, its output end will carry the two auxiliary components to move toward the middle or both sides at the same time through two moving components, so as to ensure that the centers of the two auxiliary components are always aligned with the centers of the two clamping plates 3, and then the bottles can be automatically smoothed when they pass by, so that they can be clamped stably by the two clamping plates 3 and are not prone to tilting, falling or getting stuck.

[0022] As a preferred solution of the present invention, the extension assembly includes a U-shaped frame 11, two mounting rods 17 and two extension plates 10, the adjacent ends of the two mounting rods 17 are respectively fixedly connected to the two sides of the support plate 6 close to the end of the conveyor belt 1, the ends of the two mounting rods 17 away from each other are respectively fixedly connected to the same end of the two extension plates 10, the other ends of the two extension plates 10 are respectively connected to the two ends of the thickness monitoring mechanism, the upper surfaces of the two extension plates 10 away from the ends of the mounting rods 17 are respectively fixedly connected to the two ends of the U-shaped frame 11, and the middle part of the U-shaped frame 11 is connected to the support assembly.

[0023] More specifically, by providing an extension component, support can be provided to components such as the thickness monitoring mechanism and the support component, thereby preventing the thickness monitoring mechanism and the support component from shaking, tilting, or falling.

[0024] As a preferred solution of the present invention, the thickness monitoring mechanism includes a sensor transmitting end 12 and a sensor receiving end 16, which are respectively fixedly connected to one end of the two extension plates 10 away from the mounting rod 17, and the sensor transmitting end 12 and the sensor receiving end 16 are arranged opposite to each other.

[0025] More specifically, when a bottle passes by, it will pass right between the sensor transmitting end 12 and the sensor receiving end 16. While passing through the sensor transmitting end 12 and the sensor receiving end 16, the bottle will be monitored by the sensor transmitting end 12 and the sensor receiving end 16 at the same time, and the monitored data will be synchronously transmitted to the external processor, and the PLC controller will immediately start the No. 1 self-adjusting mechanism and the No. 2 self-adjusting mechanism. It should be noted that the sensor transmitter 12 and the sensor receiver 16 can use a beam-type photoelectric sensor. The principle is that the transmitter and the receiver are beamed against each other. When an object blocks the light beam, the diameter is calculated by the time of flight (ToF). This is an existing technology and will not be described in detail here.

[0026] As a preferred solution of the present invention, two movable grooves 21 are opened through the upper surface of the U-shaped frame 11, and the two movable components are respectively located in the two movable grooves 21. Four sliding grooves 7 are opened on the upper surface of the support plate 6, and the No. 1 self-adjusting mechanism is located in the four sliding grooves 7.

[0027] More specifically, by setting the moving groove 21, a moving track can be provided for the moving component, and at the same time the moving component can be restricted to prevent the moving component from falling; by setting the sliding groove 7, the No. 1 self-adjusting gripping moving track can be provided, and at the same time the moving component can be restricted to prevent the moving component from tilting.

[0028] As a preferred solution of the present invention, the support assembly includes three support blocks 18, the lower ends of the three support blocks 18 are fixedly connected to the upper surface of the U-shaped frame 11, and the three support blocks 18 are staggered with the two movable grooves 21, and the three support blocks 18 are all connected to the No. 2 self-adjusting mechanism.

[0029] More specifically, by providing three support blocks 18, the second self-adjusting mechanism can be stably supported to prevent the moving component from shaking, tilting or falling.

[0030] As a preferred solution of the present invention, the No. 2 self-adjusting mechanism includes an adjusting motor 13 and a No. 2 bidirectional screw rod 19. The outer wall of the adjusting motor 13 is fixedly connected to the upper end of one of the support blocks 18. The output shaft of the adjusting motor 13 is fixedly connected to one end of the No. 2 bidirectional screw rod 19. The other end of the No. 2 bidirectional screw rod 19 passes through the three support blocks 18 and is rotatably connected to the three support blocks 18. The No. 2 bidirectional screw rod 19 is connected to the upper ends of both moving components.

[0031] More specifically, when the sensor transmitting end 12 and the sensor receiving end 16 detect the thickness of the bottle passing by, the external PLC controller immediately turns on the adjusting motor 13, and the output shaft of the adjusting motor 13 immediately rotates the second bidirectional screw rod 19, and then the second bidirectional screw rod 19 can move the moving component connected to its surface and restricted by the moving groove 21.

[0032] As a preferred solution of the present invention, the moving assembly includes a moving block 20, a slider 25 and two anti-slip blocks 22. The moving block 20 is sleeved and threadedly connected to the outer wall of the No. 2 bidirectional screw 19. The bottom surface of the moving block 20 is fixedly connected to the upper surface of the first anti-slip block 22. The bottom surface of the first moving block 20 is fixedly connected to the upper end of the slider 25. The lower end of the slider 25 passes through the bottom of the moving groove 21 and is fixedly connected to the upper surface of the second moving block 20. The bottom surface of the second moving block 20 is connected to the upper end of the auxiliary assembly, and the slider 25 is slidably connected to the moving groove 21.

[0033] More specifically, after the No. 2 bidirectional screw rod 19 rotates, the moving block 20 connected to the No. 2 bidirectional screw rod 19 cannot rotate because it is restricted by the moving groove 21, so the moving block 20 can only passively move laterally. When the moving block 20 moves, it can move with the slider 25 and the two anti-slip blocks 22 connected to it, thereby moving with the auxiliary components.

[0034] As a preferred solution of the present invention, the auxiliary component includes an adjustment plate 14 and a suspension rod 23, the upper end of the suspension rod 23 is fixedly connected to the bottom surface of the second moving block 20, and the lower end of the suspension rod 23 is fixedly connected to the upper surface of the adjustment plate 14.

[0035] More specifically, when the slider 25 and the two anti-slip blocks 22 move, the suspension rod 23 connected to the bottom surface of the second movable block 20 can move together. The movement of the suspension rod 23 can move the adjustment plate 14. Since the two adjustment plates 14 are both inclined, the bottle passing between the two adjustment plates 14 will be automatically straightened and aligned with the center of the two clamping plates 3.

[0036] As a preferred solution of the present invention, scale lines 24 are provided on the upper surface of the U-shaped frame 11 .

[0037] More specifically, by setting the scale lines 24 , the distance between the two adjustment plates 14 and the two clamping plates 3 at this time can be more intuitively understood, which is convenient for recording.

[0038] As a preferred solution of the present invention, the No. 1 self-adjusting mechanism includes a moving motor 8, a slide rod 9, a No. 1 bidirectional screw rod 15, four sliders 25 and a number of support rods 5. The outer wall of the moving motor 8 is fixedly connected to the side wall of the support plate 6, and the output shaft of the moving motor 8 is fixedly connected to one end of the No. 1 bidirectional screw rod 15. The No. 1 bidirectional screw rod 15, the slide rod 9 and the number of support rods 5 are arranged in parallel. The upper ends of the four sliders 25 are respectively fixedly connected to the bottom surfaces of the two clamping plates 3, and the four sliders 25 are respectively slidably connected to the four slide grooves 7. The No. 1 bidirectional screw rod 15 and the end of the slide rod 9 away from the moving motor 8 respectively pass through the four slide grooves 7 and the four sliders 25. The No. 1 bidirectional screw rod 15 is threadedly connected to the two penetrated sliders 25, the slide rod 9 is slidably connected to the two penetrated sliders 25, the two ends of the number of support rods 5 are respectively fixedly connected to the two auxiliary frames 4, and the number of support rods 5 are slidably connected to the two clamping plates 3.

[0039] More specifically, when the sensor transmitting end 12 and the sensor receiving end 16 detect the thickness of the passing bottle, the external PLC controller immediately starts the moving motor 8, and the output shaft of the moving motor 8 drives the No. 1 bidirectional screw rod 15 to rotate. After the No. 1 bidirectional screw rod 15 rotates, it can drive the two sliders 25 connected to it to move in the two slide grooves 7. In conjunction with the slide rod 9 and several support rods 5, it can ensure that the two clamping plates 3 can move stably and synchronously, so that the passing bottle can be clamped.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
