Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically separating can lid polymers supplied in stacks one by one and then transferring the polymer to a device for inspecting and sorting the inner and outer surfaces of the can lids. , by improving the conventional manual method of picking out and inspecting each sheet one by one, and automatically doing this.
The purpose is to significantly improve efficiency.

To explain the outline of the apparatus that employs the method of the present invention, a can lid separation roller hooks the lower part of the can lid at one end of the conveyor that transfers the can lid polymer, and separates the can lid one by one. A device is installed to transport the separated can lids one by one to an inspection and sorting conveyor.

To explain the device in detail with reference to the drawings, a round belt 3 is endlessly installed around a drive side round pulley 1 and a driven side round pulley 2. This round belt 3 is driven by a power unit motor 4, which rotates a shaft 7 via sprockets 5 and 6, and rotates a round pulley 1 attached to the shaft 7. In addition, 8 is a chain, 9 is a square flange bearing, 10 is a driven shaft, and 11 is a square flange bearing.

The rotation of the can lid separation roller 12 is zero max 1
3. The shaft 16 is rotated via the sprockets 14 and 15, and the can lid separation roller 12 attached to the shaft 16 is rotated.

In the apparatus described above, the can lid polymer 17 is manually supplied to a supply trough 18 as shown in the first figure and conveyed by a round belt 3. During this transportation, the can lid polymer 17
It shall be held down by the upper round bar guide 20 to prevent it from falling.

FIG. 5 shows the state in which the can lid 21 is separated from the can lid polymer 17.
7' is held down by the plate spring 22, the bottom part 23 of the tip 21' of the can lid comes into contact with the can lid separation roller 12, and the can lid 21' is scooped out from under the can lid polymer 17. They will be separated. The power unit 4 is variable speed, and the round belt speed can be adjusted from 0.1 to 0.4 m/min. Also, since the can lid separation roller has a variable speed ZERO MAX (trade name), its rotation can be adjusted from 0 to 330 rpm. After all, the can lid polymer 17 slowly fed by the round belt 3 can be separated by increasing the circumferential speed of the can lid separation roller 12.

As shown in Figure 5, in the above embodiment, the speed of the round belt 3 is V = 3.14 x 112φ x 1 rpm = 0.35.
The speed of the can lid separation roller in m/min is V=3.14×
80φ×25rpm=6.28m/min.

The can lids 21 are separated one by one from the can lid polymer 17 as described above and are transferred to the inspection and sorting conveyor 24 as shown in the first figure.

In this way, the present invention automatically separates can lids supplied in stacks one by one, and further transfers this to an inspection and sorting device, which manually separates can lids one by one from a bag containing 200 lids. When taking out sheets for inspection and sorting, the inspection and sorting capacity is 20 sheets per minute for one person, whereas when using the method of the present invention, it is 120 sheets per minute for four people.
Since the throughput per minute can be achieved, it is possible to reduce the number of people by two, thereby providing an extremely effective and appropriate method for inspecting and sorting the inner and outer surfaces of this type of can lid.

Claims (1)

[Scope of Claims] 1. At one end of a can lid transfer conveyor for separating can lids one by one from the can lid polymer, the upper part of the tip of the can lid polymer being transferred is held down by a plate spring, and, The bottom of the can lid at the tip is brought into contact with a can lid separation roller whose circumferential speed is higher than the speed of the transfer conveyor to separate one can lid and then transfer the can lid. A method for automatically separating can lids from can lid polymers.
