Abstract

The invention discloses a plastic bottle mouth forward and reverse detection device, comprising: the device comprises a bearing pushing cylinder (1), a bottle pressing cylinder (2), a limit switch (3), a shell (4), a U-shaped plate (5), a bottle body shaping cover plate (6), a bolt (7), a soft plastic bottle (8), a buffer spring (9), a material channel (10), a bearing (11), a push plate (12), a compression spring (13) and a straight groove (14). The soft plastic bottles are fed into the feeding channel through the vibration disc, and the bottle pressing cylinder pushes the bottle body shaping cover plate downwards to extrude the bottle bodies for shaping and fixing the positions; the bearing passes through feed mechanism and gets into the material and says, when the plastic bottle bottleneck is forward, pushes away the bearing cylinder and says the bearing along the material and push the soft plastic bottle and accomplish the bottling in, when the plastic bottle bottleneck is reverse, the bearing can't get into and leads to limit switch-on and send alarm signal in the bottle. The plastic bottle feeding device is simple in structure, equipment faults caused by wrong plastic bottle feeding directions can be effectively avoided, and the production efficiency of enterprises is improved.

Description

Plastic bottle bottleneck forward and reverse detection device

Technical Field

The invention relates to a plastic bottle mouth forward and reverse detection device for an automatic bearing bottling device, in particular to a plastic bottle mouth forward and reverse detection device capable of shaping and positioning a plastic bottle during automatic bearing bottling.

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.

Disclosure of Invention

The invention provides a forward and reverse detection device for a plastic bottle mouth, which is used for performing forward and reverse detection on the plastic bottle mouth supplied by a vibration disc, can avoid equipment failure caused by reverse plastic bottle, and is simple in structure, reliable in operation, convenient and practical.

The invention provides the following scheme for solving the technical problem:

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 invention will be further described with reference to the accompanying drawings in which:

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.
