Description

Technical Field

[0001] The utility model relates to the technical field of bottle and can conveying, in particular to a bottle standing device. Background Art

[0002] In the production process of small bottle and can packaging products, the bottle body is usually in a vertical state and transported on the conveyor line. However, due to the small diameter of small bottles and cans (10-50mm in diameter), they are prone to tipping over during high-speed transportation. Therefore, in the X-ray inspection section, the bottle body will be tipped over and laid flat on the conveyor belt for transportation inspection. After the X-ray inspection, the small bottle and can products need to be re-erected to enter the subsequent section. However, the bottle clamps and bottle standers on the existing market have a height difference between the bottom of the bottle and the conveyor line after the bottle is erected. Due to the small diameter of small bottle and can products, there is a risk of tipping over. Therefore, how to avoid the risk of small bottle and can products tipping over after the bottle is erected has become a problem that needs to be solved in this field. Utility Model Content

[0029] Example:

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a bottle stand device, which includes a base frame 1, a distance adjustment mechanism 2, a bottle clamping conveying end 3 and a bottle stand baffle 4, which is used to convey small bottle can products 5. The distance adjustment mechanism 2 and the bottle stand baffle 4 are fixedly connected to the top of the base frame 1, the bottle clamping conveying end 3 is fixedly connected to the distance adjustment mechanism 2, and the bottle clamping conveying end 3 includes a symmetrical first clamping conveying mechanism 31 and a second clamping conveying mechanism 32, and there is a gap between the two, and the width of the gap is smaller than the outer diameter of the small bottle can product 5, which is convenient for clamping and conveying the small bottle can product 5. The base frame 1 is welded by square tubes, and the material is stainless steel and sheet metal processing.

[0031] like Figure 3 As shown, the distance adjustment mechanism 2 is assembled by a bottom plate 21, a fixed support plate 22, a movable support plate 23, a support shaft 24, and a movable screw 25, and also includes a movable screw base 26. The bottom plate 21 is fixedly connected to the top of the base frame 1, the fixed support plate 22 and the movable support plate 23 are fixedly connected to the bottom plate 21, and are connected to the movable screw 25 through the support shaft 24, the first clamping and conveying mechanism 31 is fixedly connected to the fixed support plate 22, and the second clamping and conveying mechanism 32 is fixedly connected to the movable support plate 23. The support shaft 24 and the movable screw 25 connect the bottom plate 21 and the fixed support plate 22, and the movable support plate 23 is fixedly connected to the movable screw base 26. The distance between the clamping and conveying mechanisms on both sides, that is, the width of the gap, is controlled by adjusting the movable screw 25, so as to package products of different sizes of bottles and cans.

[0032] The first clamping and conveying mechanism 31 and the second clamping and conveying mechanism 32 are symmetrically arranged and have the same structure. Taking the second clamping and conveying mechanism 32 as an example, the specific structure is as follows: Figure 4As shown. The clamping conveying mechanism includes a mounting plate 321, a motor 322, a first transmission mechanism, a second transmission mechanism and a synchronization mechanism, and also includes a lower foam conveyor belt 323 and an upper foam conveyor belt 324 placed above the lower foam conveyor belt 323. The ends of the lower foam conveyor belt 323 and the upper foam conveyor belt 324 are misaligned to form an overlap interval A. The first transmission mechanism includes a first active roller shaft 325, a first driven roller shaft 326, a first bearing seat and a second bearing seat 327. The first bearing seat and the second bearing seat 327 are both fixedly connected to the mounting plate 321. The first active roller shaft 325 and the first driven roller shaft 326 are respectively located at the two ends of the lower foam conveyor belt 323, and are respectively equipped with the first bearing seat and the second bearing seat 327. The motor 322 is installed on the mounting plate 321 and is connected to the first active roller shaft 325. The second transmission mechanism includes a second active roller shaft 328 and a second driven roller shaft 329 fixedly connected to the mounting plate 321, and the second active roller shaft 328 and the second driven roller shaft 329 are respectively located at the two ends of the upper foam conveyor belt 324. The synchronization mechanism includes a first synchronous wheel 330, a second synchronous wheel and a synchronous belt 331, the first synchronous wheel 330 is sleeved on the first active roller shaft 325, the second synchronous wheel is sleeved on the second active roller shaft 328, the synchronous belt 331 is sleeved on the first synchronous wheel 330 and the second synchronous wheel, and the first active roller shaft 325 and the second active roller shaft 328 are respectively located at the two ends of the synchronous belt 331.

[0033] As for the second clamping conveying mechanism 32, when the motor 322 drives the first active roller 325 of the lower foam conveying belt 323 to work, the first active roller 325 drives the corresponding lower foam conveying belt 323 to rotate. At the same time, since the first synchronous wheel 330 is sleeved on the first active roller 325, the second synchronous wheel is sleeved on the second active roller 328, and the synchronous belt 331 is sleeved on the first synchronous wheel 330 and the second synchronous wheel, the first active roller 325 drives the first synchronous wheel 330 to rotate, the first synchronous wheel 330 drives the second synchronous wheel to rotate through the synchronous belt 331, and the second synchronous wheel drives the second active roller 328 to rotate. Therefore, the first active roller 325 can drive the second active roller 328 to rotate, and the second active roller 328 further drives the corresponding upper foam conveying belt 324 to rotate synchronously. In this way, one motor 322 can simultaneously drive the upper and lower foam conveying belts to rotate, and the rotation direction and speed are the same.

[0034] Due to the symmetrical arrangement, the first clamping and conveying mechanism 31 is also equipped with the same structure as the second clamping and conveying mechanism 32, and the working process is also the same. The lower foam conveyor belt of the first clamping and conveying mechanism 31 and the lower foam conveyor belt of the second clamping and conveying mechanism 32 are the inverted bottle conveying area; the upper foam conveyor belt 324 of the first clamping and conveying mechanism 31 and the upper foam conveyor belt 324 of the second clamping and conveying mechanism 32 are the standing bottle transition area, and the standing bottle baffle 4 is installed in the overlapping section A of the upper and lower foam conveyor belts. That is, the standing bottle baffle 4 is fixedly connected to the gap corresponding to the position of the overlapping section A. The end of the standing bottle baffle 4 close to the entry of the small bottle and can product 5 is semicircular, and the end away from the entry of the small bottle and can product 5 is connected to the rear production line conveyor belt 6, and the upper surface of the standing bottle baffle 4 and the upper surface of the rear production line conveyor belt 6 are located on the same plane. The standing bottle baffle 4 is made of POM plastic.

[0035] The screw rod is adjusted according to the outer diameter of the small bottle product 5, so that the distance between the foam conveyor belts on both sides is smaller than the outer diameter of the small bottle product 5. At the same time, the foam conveyor belt has a certain deformation ability. When the small bottle product 5 enters the bottle-turning conveying area, it will be squeezed by the foam conveyor belts on both sides, thereby driving the small bottle product 5 forward; when the bottom of the small bottle product 5 contacts the bottle baffle 4, since the end of the bottle baffle 4 near the entrance is a semicircular arc (the radius is 1 / 2 to 2 / 3 of the bottle bottom diameter), and the lower foam conveyor belts on both sides have been driving the small bottle product 5 forward, the small bottle product 5 will gradually stand up to a vertical state, and then enter the bottle transition area and be clamped and advanced by the upper foam conveyor belts on both sides. In practice, the upper surface of the rear production line conveyor belt 6 is adjusted to be flush with the upper surface of the bottle baffle 4 to ensure that the small bottle product 5 clamped by the upper foam conveyor belts on both sides can be stably transitioned to the subsequent production line without height difference.

[0036] The working principle of the bottle standing device provided in this embodiment is:

[0037] like Figure 1 and Figure 3 As shown, the bottle clamping conveying end 3 is installed on the distance adjustment mechanism 2, and the first clamping conveying mechanism 31 and the second clamping conveying mechanism 32 are symmetrically installed on the fixed support plate 22 and the movable support plate 23 respectively. The distance between the clamping conveying mechanisms on both sides can be adjusted by rotating the movable screw 25 to make it smaller than the outer diameter of the small bottle product 5. The rotation adjustment of the movable screw 25 can also be used for bottle packaging products of different sizes, and the use of bottles and cans of different sizes can be completed quickly. The operation is simple and fast, and the work efficiency of the production line can be improved. This simple and fast distance adjustment mechanism has a wide range of applications. Even for bottles with smaller outer diameters, the appropriate distance between the clamping conveying mechanisms on both sides can be determined through fine adjustment.

[0038] like Figure 2As shown, after adjusting the distance between the double-layer offset foam conveyor belts on both sides of the bottle clamping conveying end 3 to be smaller than the outer diameter of the small bottle product 5, the foam conveyor belts on both sides of the bottle clamping conveying end 3 can clamp the small bottle product 5 in the inverted state and move it forward. When the bottom of the small bottle product 5 contacts the semicircular arc end of the bottle stand baffle 4, the force exerted by the lower foam conveyor belts on both sides and the resistance of the bottle stand baffle 4 can make the small bottle product 5 stand up from the inverted state to the vertical state, and the bottle stand process can be completed smoothly.

[0039] On this basis, since the ends of the lower foam conveyor belts and the upper foam conveyor belts on both sides are misaligned to form an overlapped interval, the projection of the partial section of the upper foam conveyor belt away from the entrance of the small bottle product 5 will fall on the rear production line conveyor belt 6, so that the upper foam conveyor belts on both sides will continue to exert force on the erected small bottle product 5 until the small bottle product 5 runs smoothly on the rear production line conveyor belt 6. In addition, for the clamping and conveying mechanism on each side, the motor will drive the active roller of the lower foam conveyor belt and the synchronous wheel sleeved thereon to rotate, and then the synchronous belt will drive the corresponding synchronous wheel on the other side and the active roller of the upper foam conveyor belt to rotate synchronously. In this way, the motor, synchronous wheel and synchronous belt are used to realize the synchronous rotation of the upper and lower foam conveyor belts, so that the small bottle product 5 can maintain a stable state when entering and leaving the overlapped interval A. Combined with the clamping force of the foam conveyor belts on both sides, it can fully ensure the stability of the small bottle product 5 during and after the erection process. In addition, when docking with the rear-end production line conveyor belt 6, the upper surface of the rear-end production line conveyor belt 6 can be adjusted to be flush with the upper surface of the bottle baffle 4, and the upper foam conveyor belts on both sides can transfer the vertical small bottle products 5 to the subsequent production line stably without any height difference, thereby improving the stability of the entire conveying process.

[0040] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
