Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a screening device that can identify the front and back of a product. Background Technology

[0002] The condom manufacturing process includes steps such as mold forming, baking, edge rolling, demolding, leak detection, and lubrication. After electronic inspection, the condoms proceed to the lubricant addition step, followed by packaging. The condoms that have passed electronic inspection are stored randomly after being rolled up, meaning their front and back sides are disordered. However, the packaging machine can only add lubricant from one side of the condom. For condoms in this disordered state, adding lubricant may result in lubricant being added to either the front or the back. Obviously, condoms lubricated from the back have less penetration time and lubrication compared to those lubricated from the back, thus affecting the quality and effectiveness of the condom.

[0003] Chinese Patent No. CN214348003U discloses an automatic condom reverse side detection device. It includes: a condom vibration transmitter, a condom conveying guide strip, an inflation hole below the detection position, a condom height sensor above it, a condom film position sensor and an air nozzle on one side, and a flip-up window on the other side. The condom vibration transmitter conveys condoms one by one sequentially to the detection position. The condom height sensor and the condom film position sensor detect the height and position of the unfolded condom film, respectively. Condoms detected as reversed are blown away from the detection position by the air nozzle.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: when the condom is placed naturally on a flat surface, the speed and amount of air blown from below onto the condom are difficult to control, which may lead to misjudgment of the front and back due to the condom head not being able to fully extend. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the blowing parameters are difficult to control, resulting in the condom head not being able to fully extend and causing misjudgment of the front and back sides. This invention proposes a screening device that can identify the front and back sides of the product.

[0006] The technical solution of this utility model: a screening device capable of identifying the front and back of a product, including a condom; further comprising:

[0007] The U-shaped conveyor plate connects to the output end of the vibrating transmitter to complete the position transfer of the condom. The condom continues to be conveyed forward along the U-shaped conveyor plate under the pushing action of the subsequent condoms. The left and right sides of the U-shaped conveyor plate are respectively equipped with a reverse condom blowing outlet and a fan.

[0008] An air blowing hose is installed on the wall of a through hole at the bottom of the U-shaped conveyor plate. The air blowing hose is connected to an external blower to blow air into the condom in place.

[0009] A position detection sensor, installed on the U-shaped conveyor plate, is used to detect the position of the condom;

[0010] The pressure-applying mechanism is located on both sides of the U-shaped conveyor plate and applies pressure to both sides of the bottom of the condom by descending;

Detailed Implementation

[0023] Example 1

[0024] like Figures 1-3 As shown, the present invention proposes a screening device capable of identifying the front and back of a product, including a condom 16; and further including:

[0025] The U-shaped conveyor plate 1 is connected to the output end of the vibration transmitter. It should be noted that the U-shaped conveyor plate 1 is not directly connected to the output end of the vibration sensor. The connection is only used to complete the position transfer of the condom 16. Referring to Chinese patent CN214348003U, the two are directly connected. This application only needs to connect the U-shaped conveyor plate 1 to the output end of the vibration transmitter, maintaining a certain distance. Alternatively, to improve the stability of the transfer of the condom 16, an elastic fabric can be connected between the U-shaped conveyor plate 1 and the output end of the vibration transmitter. This part is conventional technology and is not described in detail in this application. The condom 16 continues to be conveyed forward along the U-shaped conveyor plate 1 under the pushing action of the subsequent condom 16. The left and right sides of the U-shaped conveyor plate 1 are respectively provided with a reverse condom blowing outlet 2 and a fan 3.

[0026] The air blowing hose 4 is set on the wall of the through hole opened at the bottom of the U-shaped conveyor plate 1. The air blowing hose 4 is connected to an external blower and blows air into the condom 16 that is in place. The air blowing hose 4 can be freely bent and deformed.

[0027] A position detection sensor 10 is installed on the U-shaped conveyor plate 1 to detect the position of the condom 16. The position detection sensor 10 can be a capacitive sensor or a vision sensor. The capacitive sensor determines the position of an object by detecting changes in capacitance. When the condom 16 approaches the sensor, the change in capacitance triggers a signal. It is suitable for detecting the position of non-metallic objects and can be installed on a conveyor line to detect whether the condom has reached the designated position. Since the condoms 16 move forward one after another, there may be some deviation in position detection. In this case, it is better to use a vision sensor. The vision sensor uses a camera and image processing technology to detect the position and state of the object. Although the detection is better, the cost is also higher.

[0028] The pressure-applying mechanism is located on the left and right sides of the U-shaped conveyor plate 1 and applies pressure to the bottom sides of the condom 16 by descending;

[0029] A height detection mechanism is also provided, located at the top of the U-shaped conveyor plate 1, to detect the height of the top of the inflated condom 16.

[0030] Example 2

[0031] like Figures 1-2 As shown, this utility model proposes a screening device that can identify the front and back of a product. Compared with Embodiment 1, this embodiment details the structure of the pressure application mechanism.

[0032] Two sets of pressure-applying mechanisms are provided, which are respectively and symmetrically arranged on the vertical sidewalls of the left and right sides of the U-shaped conveyor plate 1. The pressure-applying mechanism includes a bottom support plate 15 set at the bottom of the vertical side of the U-shaped conveyor plate 1, a lifting device 9 vertically set on the bottom support plate 15, a lifting plate 7 set at the top telescopic end of the lifting device 9, a connecting frame 5 connected to the lifting plate 7, and a pressure rod 6 set at the bottom of the connecting frame 5; the connecting frame 5 is a U-shaped frame, and the pressure rod 6 presses down on the bottom edge of the condom 16; in an optional embodiment, the lifting device 9 is a cylinder, a hydraulic rod, or an electric push rod.

[0033] Furthermore, the pressure rod 6 is arranged along the moving direction of the condom 16. The pressure rod 6 is an elastic element, such as a rubber rod, to prevent damage to the condom 16. In order to improve the stability of the lifting plate 7 in the vertical direction, multiple guide rods 8 are vertically arranged on the bottom support plate 15. The lifting plate 7 is provided with guide holes for the guide rods 8 to pass through. In this embodiment, two guide rods 8 are provided, and the two guide rods 8 are located on the reverse condom blowing outlet 2 and on both sides of the blower 3, respectively.

[0034] Example 3

[0035] like Figure 1As shown, this utility model proposes a screening device that can identify the front and back of a product. Compared with Embodiment 2, this embodiment details the structure of the height detection mechanism and the control method of the control system.

[0036] The height detection mechanism includes a top support plate 11 set on the top of the U-shaped conveyor plate 1, clearance grooves 14 set on the left and right sides of the top support plate 11, and a height detection device 12 set on the top support plate 11 via a mounting plate 13. The clearance grooves 14 are used for the connecting frame 5 and the pressure rod 6 to pass through. The height detection device 12 is used to detect the height of the top of the inflated condom 16. The height detection device 12 is a laser rangefinder or an ultrasonic sensor.

[0037] The control system is connected to the position detection sensor 10 and the height detection device 12 for data transmission, and is also connected to the fan 3, the blower and the lifting device 9 for control.

[0038] In summary, when this utility model is in use, after the condom 16 reaches the set position, the position detection sensor 10 sends a signal to the control system. The control system controls the lifting device 9 to retract downwards, and the connecting frame 5 drives the pressure rod 6 to move downwards. The two pressure rods 6 press down the bottom edges of the condom 16. Then, the blower starts blowing air into the condom 16 through the air blowing hose 4. At the same time, the height detection device 12 detects the bottom height of the condom 16 after blowing. If the height is significantly lower than the set range, it indicates that the condom 16 is reversed. Then, the air blowing hose 4 stops air intake, the lifting device 9 extends upwards to move the pressure rod 6 to a position higher than the height of the condom 16, and the blower 3 starts to blow the reversed condom 16 out of the reversed condom blowing outlet 2. If the condom 16 is right-side up, it continues to move forward. Press down the two sides of the bottom of the condom 16 by pressing the lever 6, and then blow air. There is no need to precisely control the blowing speed and air volume. The condom 16 can be blown up smoothly. At the same time, the excess air can flow out through other unpressed parts of the bottom of the condom 16. In short, there is no need to strictly control the blowing parameters, and the condom 16 can be fully blown up, avoiding misjudgment of the front and back.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
