BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap conveying device for vertically adsorbing and capping a cap having a crown shape or a bottomed cylindrical shape by magnetic force, and in particular, a belt for conveying the cap from a hopper side. The present invention relates to a cap transfer device that smoothly transfers a cap to a conveyor.

[0002]

2. Description of the Related Art Conventionally, there is a cap transfer device that attracts a cap having a crown shape or a bottomed cylindrical shape by a magnetic force and transfers the cap vertically upward. This device consists of a hopper for charging the cap, a vertical conveyor that attracts the cap by magnetic force and transports it vertically upward, and an inclined conveyor that transports the cap from the hopper to the vertical conveyor. Since it is delivered to the vertical conveyor via the vertical conveyor, a cap receiving portion is provided below the vertical conveyor. The cap conveyed by suctioning any of the front and back by the vertical conveyor will be delivered to the next step via the sorting mechanism for sorting the front and back, and the cap on the wrong side will be returned to the hopper. .

[0003]

However, according to the above prior art, there are the following problems. Since the cap in the hopper is conveyed to the vertical conveyor via the inclined conveyor, a large installation area is required, and the hopper cannot be installed in a narrow place. In addition, a drive source for driving the vertical conveyor and a drive source for driving the inclined conveyor are required. When transporting inside a factory in a flammable atmosphere such as a paint can cap, two drive sources (for example, motors) are explosion-proof. It has to be a specification and the cost is high.

It is conceivable that the caps in the hopper are directly delivered to the vertical conveyor. In this case, the caps in the mixed state in the hopper are supplied from the lower outlet to the belt conveyor side. Due to the weight of the cap, the front and back sides of the cap are not attracted to the vertical conveyor, and the transport efficiency of the cap is reduced.

The present invention has been made in view of the above-mentioned problems, and provides a cap transfer device which can be installed in a narrow place, can be reduced in cost, and can improve transfer efficiency. It is in.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a cap conveying device having a belt conveyor for vertically adsorbing a cap in a hopper by magnetically attracting the cap inside the hopper. An opening protruding downward at the lower part of the hopper to be extended, a block slidable in the up and down direction is provided in the opening, and a moving mechanism for moving the block in the up and down direction is provided. The upper surface of the block is formed to be inclined toward the belt conveyor, and the upper surface of the block is formed to have a V-shaped inclination.

[0007]

According to the present invention, the operation is as follows. The block moves up and down in an opening provided in the lower part of the hopper by an appropriate stroke by a moving mechanism. Thereby, the posture of the cap in the vicinity of the belt conveyor is changed from the horizontal direction to the vertical direction, so that the cap is relatively easily attracted to the belt conveyor. In the case where the upper surface of the block is formed to be inclined toward the belt conveyor, the inclination changes the posture of the cap from the horizontal direction to the vertical direction. Since the cap has a certain angle from the horizontal direction due to the inclination of the V-shape, the cap is easily attracted to the belt conveyor by magnetic force. By adjusting the block vertical stroke amount, the speed thereof, and the speed of the belt conveyor in accordance with the cap filling amount in the hopper, efficient cap supply becomes possible.
