Description

[Detailed description of the invention] This invention relates to a device that feeds rod-like objects stored in a hopper one by one into a forming machine such as a press, and more specifically, when the conveyor is reversed, it comes into contact with the rod-like objects on the pedestal. , a swingable plate whose tip faces the transfer direction and is located above the pedestal, and a limit switch that stops the reversal of the conveyor when the swinging plate retreats are installed on the hopper side plate, so that the rod-shaped object can be moved to the hopper. This invention relates to a device that prevents damage to the conveyor and hopper by preventing the conveyor from being caught between the conveyor and the hopper.

Conventionally, when a bar-shaped object is transferred by a conveyor, if the bar-shaped object gets caught between the guide member provided at the top of the downstream side of the conveyor, the conveyor is reversed to release the jamming. A rod-like object often got caught between the hopper and the conveyor, deforming the hopper and damaging the conveyor. The present invention has been devised in view of the above drawbacks, and one embodiment thereof will be described below with reference to the drawings.

1 is a short rod-shaped object M suspended from sprockets 31, 32, and 33 provided on an L-shaped frame 2.
A plurality of pedestals 4 each having a semicircular recess that supports the
5 is a hopper provided on the upstream side of the conveyor 1 for accommodating a large number of rod-like objects M; 6 is a hopper that rotates the sprocket 33 via a chain 7; This is an electric motor that rotates the motor counterclockwise. 8 is a guide member located slightly above the rod-shaped object M on the pedestal 4 provided at the top of the pedestal 2; 9 is a guide member provided on the guide member 8 when the rod-shaped object M comes into contact with the guide member 8; , a limit switch that stops the operation of the electric motor 6 and then reverses the conveying direction of the conveyor 1. 10 is an outer plate 11 on the upstream side of the hopper 5
13 through the bracket 12.
The supporting plate 1 is positioned slightly above the pedestal 4 with its tip facing the conveying direction of the conveyor 1.
4, and the other end is held by a stopper 15.
16 is a rocking plate pivotally connected to the link 10 and prevented from moving forward by the rocking plate 1.
3 is a limit switch that stops the reverse rotation of the conveyor 1, which is provided at a position that the conveyor 1 comes into contact with when retracting.

Next, the effects will be explained.

When a large number of rod-like objects M are stored in advance in the hopper 5 and the sprocket 33 is rotated via the chain 7 by driving the electric motor 6, the chain conveyor 1 suspended on the sprockets 31, 32, and 33 is rotated.
is rotated counterclockwise, and the rods M in the hopper 5 are supported one by one in the recesses formed in the pedestal 4, and transferred to a molding device (not shown) via the top of the L-shaped pedestal 2. It is. However, if the rod-shaped object M is often transferred without being properly fitted into the recess on the pedestal 4, the rod-shaped object M comes into contact with the guide member 8 provided at the top of the pedestal 2, and the rod-shaped object M is bitten. . In this case, the limit switch 9 provided on the guide member 8 is activated to stop the rotation of the electric motor 6 and stop the transfer of the conveyor 1, and then, after a predetermined period of time, the direction of transfer of the conveyor 1 is reversed so that the guide member 8 and the rod-like object This solves the problem with M. By the way, when the chain conveyor 1 is reversed, if the rod-shaped object M is not fitted into the recess on the pedestal 4 at the lower part of the hopper 5, the rod-shaped object M will be moved to the pedestal due to the reversal of the conveyor 1. 4
Either it falls further, or it retreats while engaging with the recess of the pedestal 4. When the rod-shaped object M is moved backward in the engaged state, the rod-shaped object M comes into contact with the tip of the rocking plate 13 provided on the side plate of the hopper 5 via the link 10, and the rocking plate 13 is moved backward by the rotation of the link 10. The rear part thereof contacts the limit switch 16.

Then, the limit switch 16 turns the electric motor 6
By stopping the operation of the conveyor 1 and preventing the conveyor 1 from reversing, the rod-shaped object M will not be caught.

In the above embodiment, a case has been described in which the chain conveyor 1 is suspended on the L-shaped pedestal 2. However, the pedestal 2 is rectangular, and the chain conveyor 1 is simply suspended from the L-shaped pedestal 2. This can also be applied to the case where M is transported horizontally.

As mentioned above, when the conveyor is reversed, the swingable plate that comes into contact with the rod-shaped object on the pedestal, its tip facing the transfer direction, and located above the pedestal, and the oscillating plate move back. A limit switch that stops the reversal of the conveyor is installed on the side plate of the hopper to prevent rod-like objects from getting caught between the hopper and the conveyor, which prevents damage to the conveyor or hopper and contributes to industry. However, it is large.
