Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a break device for a bridge used in a feeder for feeding a collected material dropped in a trough to a discharge port by a transfer device.

[0002]

[Prior Art]

 Generally, when the collected material dropped into the feeder trough is sent by the transport device and exits to the discharge port, the collected product forms a bridge above the transport device and cannot fall into the discharge port. The phenomenon often occurs.

Therefore, how to break such a bridging phenomenon is one of the most important points in designing this kind of feeder.

From this point of view, conventionally, when a collected product is conveyed in the feeder, the bridge generated in the collected product is broken by vibrating the trough with vibration or applying an impact using an air knocker. The means to do so has been taken.

[0005]

[Problems to be solved by the device]

 However, with such an indirect bridge break means, if the recovered material is in the form of powder or particles, the recovered material discharged from the machine tool, such as a chip recovery device of a machine tool, will still be used. If the cutting chips are curled, they are intertwined with each other, and the above-mentioned break means of the bridge is too weak to exert a sufficient break function. On the contrary, there was a drawback that the collected materials were complicatedly entangled to promote the bridge.

Therefore, an object of the present invention is to provide a feeder that can reliably break and convey not only powdery or granular recovered matter but also any kind of recovered matter such as curled cutting chips. The present invention is to provide a bridge break device.

[0007]

[Means for solving the problem]

 In order to achieve the above object, according to the present invention, a bridge breaker is disposed above a transfer device installed at the bottom of the trough in parallel with the transfer device by a bearing so as to be movable. The bridge breaker was connected to a pneumatic drive unit attached to a trough via a joint.

[0008]

[Action]

 This allows the bridge breaker to be driven by the pneumatic drive member with a soft operating force, even if the collected products that have formed bridges are intertwined with each other, such as curled chips. , It acts without exerting an excessive force on the collected material, and it does not complicate the entanglement of the collected material to promote the bridge, but acts to loosen it and surely breaks the bridge.

【Example】

 The invention will be described below with reference to the drawings.

As shown in FIG. 1, a feeder A, which is an embodiment of the present invention, is provided with a screw type conveying device 2 at the bottom of a trough 1, and a discharging port 3 is provided at a conveying end of the conveying device 2. It is provided.

The transport device 2 is configured to be rotationally driven in the transport direction through the reduction mechanism 6 by an electric motor 5 mounted on the frame 4 of the trough 1, and the discharge port 3 is connected downward. It also leads to a suction device (not shown) through the transport pipe 7.

On the other hand, the trough 1 is provided with a pushing device 8 facing the discharge port 3 for dropping the collected material B into the discharge port 3, and the pushing device 8 is driven by the control device 9. It is composed of an electric motor 10 to be controlled and a screw type feed member 11 which is rotationally driven by the electric motor 10.

The bridge break device, which is a feature of the present invention, includes a bridge breaker 12 disposed above the carrier device 2 in parallel with the carrier device 2 in the trough 1, and a trough facing the bridge breaker 12. 1 is an air-type driving member 13 attached to the outer wall.

In the case of this embodiment, the bridge breaker 12 is configured as a shaft 15 having a plurality of blades 14 mounted by shifting the phase by 90 degrees, and the shaft mounting the shaft 15 to the trough 1. It is movably supported by 16 and 17.

Similarly, in the case of this embodiment, the air driving member 13 is composed of an air cylinder that is driven and controlled by the control device 9, and the piston rod 18 of this air cylinder is bridged via a floating joint 19. It is connected to the shaft 15 of the breaker 12. Next, the operation will be described.

The collected material B put into the trough 1 is carried to the discharge port 3 of the trough 1 by the carrying device 2 installed at the bottom, and falls from the discharge port 3 into the carrying pipe 7 below. Then, it is carried out by the suction device.

When a large amount of collected material B is put into the trough 1, the collected material B may stay in a bridge shape on the upper side of the transfer device 2 and may not drop on the transfer device 2 any more. Occurs.

When such a situation occurs, the bridge breaker 12 disposed above the transport device 2 is intermittently reciprocated by the control device 9 through the drive member 13, and the bridge breaker 12 is moved by the movement of the bridge breaker 12. The bridge formed in the collected material B is broken, the collected material B is dropped downward, and is conveyed to the discharge port 3 by the conveying device 2.

In this case, since the bridge breaker 12 is driven by the pneumatic drive member 13 having a soft operation force, the bridge breaker 12 acts without exerting an unreasonable force on the collected material B, and therefore the collected material B For example, even if curl-shaped chips are used, they are used in a loosening direction without complicatedly intertwining them to promote the bridge.

In this way, the bridge breaker 12 acts as a bridge breaker by breaking the mountain of the recovered material B in the trough 1 to make it uniform in height and also breaking the tunnel shape of the bridge.

Similarly, when a bridge occurs in the collected material B at the discharge port 3, the control device 9 drives the electric motor 10 of the pushing device 8 to rotate the feed member 11 to rotate it. The feeding member 11 breaks the bridge of the recovered material B and drops it from the discharge port 3 into the lower transfer pipe 7.

Thus, the collected product B is efficiently carried out to the outside while repeating the above-mentioned operation.

[0023]

【The invention's effect】

 As described above, according to the present invention, it is possible to reliably break and transport not only powdery or granular recovered materials but also bridges of all recovered materials such as curled cutting chips. become.
