Detailed Description

As shown in fig. 1, the conveying structure 10 of the present invention mainly includes a rail 12, a plurality of slide-shaped carriers 14 disposed on the rail 12 for arranging bottle blanks (not shown), and a driving device 16 capable of driving each carrier 14 to move.

As shown in fig. 1 and 2, the track 12 is a generally rectangular shape having two pairs of straight segments 20 and four arcuate segments 30 adjacent the straight segments 20. The straight section 20 includes two first extending members 22 extending in parallel, and a first bearing portion 24 and a first limiting portion 26 respectively disposed on the first extending members 22. The first extension member 22 is formed by combining an upper plate 23 for disposing the first bearing portion 24 and a lower plate 25 for disposing the first restriction portion 26 via a plurality of bolts 27. As shown in fig. 3, the arc-shaped segment 30 includes two corresponding second extending members 32 extending in parallel, a second bearing portion 34 and a second limiting portion 36 respectively disposed on the second extending members 32, and a sheet-shaped stopping portion 38 disposed above the extending members 32.

As shown in fig. 4, each carrier 14 of the present invention can have two bottle embryo seats 40 pivoted thereon, and the upper end of each bottle embryo seat 40 protrudes above the carrier 14 and can be inserted into a bottle embryo mouth. The preform seat 40 has a roller and a gear 42 at one end extending below the carrier 14, and the carrier 14 can be used to simultaneously hold two preforms, thereby increasing the working efficiency. When the carrier 14 passes through the arc-shaped section 30, the outer edges of the lower ends of the two preform holders 40 are simultaneously rotated to contact the second limiting portions 36 outside the arc-shaped section 30.

When each carrier 14 is sequentially placed on the straight line segment 20 of the rail 12, as shown in fig. 2, two parallel long sides of each carrier 14 are respectively spanned on the corresponding first bearing portions 24, and the two sides are respectively limited by the first limiting portions 26, so that the carriers are not deflected.

The driving device 16 is a pneumatic cylinder capable of directly pushing a carrier 14 from one end of the straight line segment 20 to move horizontally, the driving device 16 can also be a mechanical arm arranged at any position of the track 12, as shown in fig. 5, the mechanical arm comprises a pair of mechanical arms 160, and a small cylinder 161 and a frame 162 for pushing the mechanical arms 160 to open and close, the mechanical arms 160 can grasp a carrier 14 and force the carrier 14 to slide a distance along the extending direction of the track 12, so that the driving device 16 can push only one carrier 14 by virtue of the carriers 14 arranged closely and continuously without gap, and all the carriers 14 on the conveying device 10 can move synchronously a same distance therewith. As shown in fig. 6, the robot 160 pushes the entire robot system forward along the rail 12 by another larger cylinder 163.

In addition, because the carriers 14 are arranged on the track 12 in sequence without gaps in the whole process, no gap part which is required to be arranged in the traditional way is formed at the turning position or the position driven by the driving device 16, and the noise which is possibly generated due to the collision of the carriers when the carriers move forwards in an intermittent way can be greatly reduced.

When each carrier 14 is pushed to reach the arc section 30, as shown in fig. 3, the carrier 14 still straddles the two long sides on the second carrying portion 34, but the two sides of the carrier do not contact the second extending member 32, and the outer edge of the lower end of each preform seat 40 or the outer edge of the roller abuts against the second limiting portion 36 located outside the arc section 30, and rotates or rolls on the abutting end surfaces. The stoppers 38 above the two sides of each carrier 14 are used to limit each carrier 14 from tilting at the arc section 30 due to the rotation.

Alternatively, the carrier 14 may be formed in a circular plate shape having a suitable thickness, and a preform seat 40 may be disposed at the axial center thereof, such that the circular carrier (not shown) may contact the first limiting portion 26 at the periphery thereof when moving on the straight section 20, and may contact the second limiting portion 36 at the pivotable lower end of the preform seat 40 when moving on the curved section 30.

In order to further reduce the noise generated by friction during the movement of each carrier 14, a slightly elastic wear-resistant sheet-like buffer element is fixed at the periphery of each carrier 14 contacting with another carrier 14 by embedding or adhering, and the impact force and noise between two adjacent carriers 14 are absorbed by the wear-resistant sheet-like buffer element.

The utility model provides a conveyor has following advantage:

1. since the rail 12 is connected to the straight sections 20 by the arc sections 30, there is no right angle portion, so that the carriers 14 can slide on the rail 12 more smoothly.

2. Because each carrier 14 can smoothly circulate on the track 12, the present invention can push each carrier 14 on the track 12 to move synchronously without using a pneumatic cylinder.

3. Because the carriers 14 pass through the arc-shaped section 30 of the rail 12 smoothly by means of the rotatable or rolling preforms 40 and the rollers 52, the conveying device 10 does not require a drive which is energy-consuming and bulky.

4. Due to the stop portion 38, the carrier 14 can be effectively prevented from being tilted due to centrifugal force when passing through the arc-shaped section 30.

5. Because the carriers 14 are arranged on the track 12 in a gapless way in the whole process, especially at the turning position or the position pushed by a driving device, the noise generation can be effectively reduced in the intermittent advancing process.
