Description

Plastic bottle bottleneck forward and reverse detection device

Technical Field

The utility model relates to a plastic bottle bottleneck forward and reverse detection device for automatic bottling device of bearing especially relates to one kind and can carry out plastic, the plastic bottle bottleneck forward and reverse detection device of location to the plastic bottle when the automatic bottling of bearing.

Background

At present, domestic bearings are mainly packaged by using soft plastic bottles, and when an automatic device bottles the bearings, the soft plastic bottles for loading the bearings are automatically fed through a vibration disc. Although the plastic bottles can be selected by feeding the vibrating plate (namely, the directions of the mouths of the supplied plastic bottles are consistent), the success rate of selecting the plastic bottles cannot be guaranteed to be 100%. When the direction of the opening of the supplied plastic bottle is wrong and no detection link is provided, the device continues to carry out bearing bottling work under the condition that the plastic bottle cannot be identified reversely, the soft plastic bottle can be crushed, and even equipment is damaged, so that production accidents are caused, and the production of a factory is influenced. However, the vibratory tray is oriented correctly for feeding most bottles, so that the orientation of each bottle mouth is detected when no feeding is required. In conclusion, it is of great significance to design a forward and reverse detection device which does not work when the direction of the plastic bottle mouth is correct and can send out an alarm signal when the plastic bottle mouth is reversed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a plastic bottle bottleneck positive reverse detection device carries out positive reverse detection to the plastic bottle bottleneck that the vibration dish was supplied with, can avoid the equipment trouble because of the plastic bottle is reverse to lead to, its simple structure, and the operation is reliable, convenient and practical.

The utility model provides a technical problem provide following scheme:

a kind of plastic bottle bottleneck forward and reverse checkout gear, comprising: the device comprises a bearing pushing cylinder, a bottle pressing cylinder, a limit switch, a shell, a U-shaped plate, a bottle body shaping cover plate, a bolt, a soft plastic bottle, a buffer spring, a material channel, a bearing, a push plate, a straight groove and a compression spring.

The U-shaped plate is provided with a hole and is connected with the bottle body shaping cover plate through a bolt.

The material channel and the bottle body shaping cover plate are provided with circular grooves, and the diameter of each circular groove is 2mm larger than that of the bearing.

The springs are compression springs, and the inner diameter of each compression spring is 3mm larger than the outer diameter of the bolt.

The limit switch is a contact switch and is fixed on the outer shell through a bolt, and the distance between a contact of the limit switch and the U-shaped plate is 10 mm.

The push plate is fixed with the shell through a bolt.

The bottom surface of the shell is provided with two straight grooves which are convenient for the U-shaped plate to move.

In the figure, 1, a bearing cylinder is pushed; 2. a bottle pressing cylinder; 3. a limit switch; 4. a housing; 5. a U-shaped plate; 6. a bottle body shaping cover plate; 7. a bolt; 8. a soft plastic bottle; 9. a buffer spring; 10. a material channel; 11. a bearing; 12. pushing the plate; 13. a compression spring; 14. straight groove

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to fig. 2, when the mouth of the soft plastic bottle is forward, the soft plastic bottle (8) enters the material channel, the cylinder (2) drives the shell (4) and the bottle body shaping cover plate (6) to move downwards, the bottle body shaping cover plate (6) is in contact with the material channel (10) and is buffered through the buffer spring (9), the soft plastic bottle (8) is shaped and fixed in position, and a bearing can conveniently enter the bottle.

Further, the bearing pushing cylinder (1) pushes the bearing (11) to completely push the bearing (11) into the soft plastic bottle (8), so that the bottling of the bearing (11) is completed.

Referring to fig. 3, when the bottle mouth of the soft plastic bottle is reversed, the cylinder (2) drives the shell (4) and the bottle body shaping cover plate (6) to move downwards, the bottle body shaping cover plate (6) is in contact with the bearing material channel (10) and is buffered by the buffer spring (9), and the soft plastic bottle (8) is shaped and fixed in position, so that the bearing can conveniently enter the bottle.

Further, the bearing pushing cylinder (1) pushes the bearing (11) to move forward, and due to the fact that the bottom of the soft plastic bottle (8) faces the bearing (11), the bearing (11) is in contact with the bottom of the soft plastic bottle and cannot enter the soft plastic bottle (8) to extrude the soft plastic bottle (8) to move forward, and the soft plastic bottle (8) pushes the bottle body shaping cover plate (6) to drive the U-shaped plate (5) to move along the straight groove (14).

Referring to fig. 4, when the left end of the U-shaped plate (5) contacts with the contact of the limit switch (3), the limit switch (3) is triggered, the device sends a feeding error signal at the moment, the bearing pushing cylinder (1) stops pushing, error correction is waited, and the reverse detection of the bottle mouth is completed.

When the reverse soft plastic bottle is taken down, the U-shaped plate (5) returns to the original position due to the restoring force of the compression spring (13), the limit switch is closed, and the bottling work of the bearing is restarted.
