Description

Fixed distance synchronous conveyor

The present invention relates to a conveying device for a part, in particular to a conveying device for conveying a rod-shaped part.

The conventional rod-shaped part A conveying device, as shown in FIG. 7, has a plurality of pressing units 91, a driving wheel 92, a plurality of guiding wheels 93, a guiding belt 94 and a guiding plate 95, and each pressing unit 91 is disposed, the transmission wheel 92 and each of the guide wheels 93 are respectively disposed on the compression unit 91, and the guide belt 94 is sleeved on the separately disposed transmission wheel 92 and the guide wheel 93, so that the guide belt 94 is pulled out. A straight line segment. A straight gap is formed between the straight section of the guiding strip 94 and the guiding plate 95, and the pressing unit 91 pushes the driving wheel 92 and the guiding wheel 93 toward the guiding plate 95, so that the straight section of the guiding belt 94 can be guided. The guide plate 95 is close. The conveying device is used in conjunction with a dispensing device B for dialing the rod-shaped member A into the gap so that the rod-shaped member A can be clamped between the guiding plate 95 and the guiding belt 94. At this time, as long as the transmission wheel 92 rotates, the guide belt 94 can be rotated and the rod-shaped member A can be moved.

However, since the compression unit 91 is disposed apart, and the transmission wheel 92 and the guide wheel 93 are also disposed apart, the pressing force applied to the guide belt 94 acts in a dotted manner on the guide belt 94. Therefore, the portion of the guide belt 94 located between the two compression units 91 can only press the rod-shaped member A by the tension of the guide belt 94. If two rod-shaped parts A of different sizes are successively inserted into the gap, the larger rod-shaped part A will support the gap between the guiding belt 94 and the guiding plate 95, causing the guiding belt 94 to be uncompressed. The portion pushed by the unit 91 cannot crush the smaller rod-shaped member A, so that the smaller rod-shaped member A cannot be gripped by the guide plate 95 and the guide belt 94 and cannot be driven by the guide belt 94. In addition, the compression unit 91 can only be in the direction of the vertical guide belt 94. The movement is performed in accordance with the size of the rod-shaped member A. When the rod-shaped member A passes through the compression unit 91, the rod-shaped member A can be pressed only by the tension of the guide belt 94, and the pressing force is insufficient.

In other words, in the conventional conveying device, the rod-shaped member A is liable to slip due to uneven friction during the conveying process. Unless only one rod-shaped part A is transported at a time, it is impossible to ensure that each rod-shaped part A maintains a fixed distance, and even if the rear rod-shaped part A catches up with the front rod-shaped part A and chases, it will affect subsequent processing. .

In view of this, providing a better improvement solution is an urgent problem to be solved in the industry.

Please refer to Figures 1 to 3 first. The present application proposes a distance synchronous conveyor that can be used to transport a plurality of rod-shaped parts A, for example, for conveying screws for processing. The distance synchronous conveyor has a guiding plate 10, a transmission assembly 20, and a compression assembly 30.

In this embodiment, the guiding plate 10 is a fixed disc without rotation, and the transmission assembly 20 and the compression assembly 30 are all disposed on the guiding plate 10.

The transmission assembly 20 has a transmission wheel 21, a tension adjustment seat 210, at least one guide wheel 22, and a guide belt 23. The transmission wheel 21 is disposed on the tension adjusting seat 210 and is connected to a power unit that rotates the transmission wheel 21 in a counterclockwise direction. At least one guide wheel 22 is spaced from the drive wheel 21. In the present embodiment, the number of the guide wheels 22 is plural, for example, six. The guide wheel 22 and the transmission wheel 21 are circumferentially disposed around the guide plate 10.

The guiding belt 23 is sleeved on the driving wheel 21 and the guiding wheel 22. Specifically, the guiding belt 23 is disposed around the guiding plate 10 through the driving wheel 21 and the guiding wheel 22, and the driving wheel 21 drives the guiding belt 23, and the guiding wheel 22 is used for guiding and guiding. The belt 23 is turned around and surrounds the guide plate 10. The shape of the guiding plate 10 corresponds to the passage path of the guiding belt 23, and the guiding plate 10 faces the outer side surface of the guiding belt 23, and a gap is selectively formed between the outer side surface of the guiding belt 23, and The rod-shaped member A is clamped between the guide belt 23 and the guide plate 10, and when the transmission wheel 21 drives the guide belt 23, the rod-shaped member A can be driven to roll on the guide plate 10. The guide tape 23 has a rib 230 formed on the inner side of the guide tape 23. Since the rod-shaped parts A to be transported can have different sizes, the gaps will vary with the diameter of the rod-shaped parts A, so that the transmission wheel 21 is held on the guide belt 23 by the adjustment position on the tension adjustment seat 210. The tension.

In other embodiments, the guide belt 23 has elasticity and can be compressed in the thickness direction, so that even if the rod-shaped parts A of different sizes are transported in the same conveyance, it is ensured that each rod-shaped part A is still guided. 23 is pressed against the guide plate 10.

The compression unit 30 is disposed on the inner side of the portion of the guide belt 23 adjacent to the guide plate 10, abuts against the inner side surface of the guide belt 23, and pushes the guide belt 23 against the guide sheet 10. Therefore, the compression assembly 30 can tend to reduce or disappear the gap between the guide sheet 10 and the guide belt 23 to sandwich the rod-shaped member A to the gap. The compression assembly 30 has a positioning plate 31 and a plurality of compression units 32.

The positioning plate 31 is disposed in the guiding belt 23 and is disposed on the guiding plate 10 . The shape of the inner edge of the positioning plate 31 corresponds to the shape of the outer circumference of the guide plate 10.

The pressing unit 32 is disposed on one side of the positioning plate 31. Each of the pressing units 32 has a positioning member 321, a pressing roller 322 and an elastic member 323.

The positioning member 321 is pivotally disposed on the side of the positioning plate 31. In the embodiment, the positioning member 321 is a triangular plate body, and the first corner 3211 is pivoted on the positioning plate 31, the second corner 3212 is connected to the elastic member 323, and the third corner 3213 is provided with the pressing roller 322. And the distance of each corner with respect to the guide plate 10 is near The far angle is a third angle 3213 provided with a compression roller 322, a first angle 3211 pivoted to the positioning plate 31, and then a second angle 3212 connecting the elastic members 323. In other words, both ends of the positioning plate 31 can be defined as the angle closest to and farthest from the guiding plate 10, that is, the third angle 3213 and the second angle 3212.

The pressing rollers 322 are looped on the guiding plate 10 and abut against the inner side of the guiding tape 23. The compression roller 322 has a recess 3220 that surrounds the outer circumference of the compression roller 322, and the 230 rib of the guide belt 23 is fitted into the recess 3220 of the compression roller 322. The pressing roller 322 has a moving stroke, and the pressing roller 322 moves along the moving path of the rod-shaped member A on the moving stroke, and the distance between the pressing rollers 322 is approximately equal to the length of the moving stroke.

One end of the elastic member 323 is connected to the second corner 3212 of the positioning member 321 , and the other end is connected to the side surface of the positioning plate 31 . Therefore, the elastic member 323 can drive the positioning member 321 to rotate, so that the compression roller 322 tends to move toward the guiding plate 10. The elastic member 323 is a spring, a torsion spring or a spring. In the present embodiment, the elastic member 323 is a tension spring. The elastic member 323 is connected to one end of the positioning member 321 which is farthest from the guiding plate 10, and the pressing roller 322 is connected to one end of the positioning member 321 which is closest to the guiding plate 10.

Through the above structure, before the device is started, due to the elastic force of the elastic member 323, the positioning member 321 is pivoted to the pressing roller 322 at the starting point of the moving stroke, so that the pressing roller 322 pushes against the guiding belt 23 The guide plate 10 minimizes or eliminates the gap between the guide plate 10 and the guide tape 23. When the device is activated, the driving wheel 21 drives the guiding belt 23 to rotate, and the position of the driving wheel 21 can be finely adjusted by the tension adjusting seat 210 to control the tension of the guiding belt 23.

Subsequently, the dispensing device B splits the rod-shaped parts A one by one between the guiding plate 10 and the guiding belt 23 and opens the gap, and by the guiding belt 23, the rod-shaped part A can be guided on the guiding plate The roller 10 is rolled up to move along the outer circumference of the guide plate 10. At this time, as shown in FIG. 4, the rod-shaped member A is pushed against the compression roller 322 of the compression unit 32 through the guide belt 23, and the compression unit 32 is pivoted and drives the compression roller 322 along the movement stroke thereof. Moving, and the pressure roller 322 gradually moves away from the guide plate 10.

Then please refer to Figure 5. When the pressing roller 322 continues to move away from the guiding plate 10, and the distance between the guiding belt 23 and the guiding plate 10 is larger than the diameter of the rod-shaped part A, the rod-shaped part A cannot be pushed against the roller 322, so the rod shape The part A is separated from the compression roller 322, at which point the compression roller 322 is located at the end of the movement stroke. The crushing roller 322 loses the force pushed by the rod-shaped member A, and is pulled back by the biasing force of the elastic member 323 to the starting point of the moving stroke. At this time, the rod-shaped member A is advanced to the subsequent pressing unit 32, and the pressing roller 322 is moved by the pushing of the next rod-shaped member A again on the moving stroke.

Therefore, as shown in FIG. 6 , during the conveying process, the positioning member 321 rotates, so the moving stroke of the pressing roller 322 is an arc path of the center of the rear positioning member 321 , and drives the guiding belt 23 to approach or away from the guiding. Board 10.

In other embodiments, the guiding plate 10 can be a rectangular plate, and the transmission assembly 20 and the compression assembly 30 are linearly distributed corresponding to the straight edge of the rectangular plate, so that the spacing of the parts A is also straight. distributed. In addition, in another embodiment, the positioning member 321 can be a swinging rod, one end of which is pivotally disposed on the positioning plate 31, and the other end is pivotally provided with a pressing roller 322, and the elastic member 323 is connected between the two ends of the positioning member 321 .

In summary, the present invention can pass through the pivotable positioning member 321 of the pressing unit 32, and the pressing roller 322 can have a moving stroke with the pivoting of the positioning member 321, and the pressing roller 322 can move thereon. The stroke moves along the moving path of the rod-shaped part A, thereby ensuring that the rod-shaped part A is continuously pressed by the pressing unit 32 during the conveying process, so that the rod-shaped part A can obtain sufficient friction to guide The board 10 is rotated. Through the above structure, the fixed-distance synchronous conveying device can simultaneously allow the rod-shaped parts A to be synchronously rolled and conveyed on the guide sheets 10 at equal intervals without occurrence of slipping or chasing.
