[0001] TRANSFER DEVICE OF FEED [0002]

The present invention relates to a driving unit main body of a feed conveying apparatus, and more particularly to a driving unit main body of a feed conveying apparatus capable of confirming the tension state of a wire from the outside of the main body, To a possible drive unit main body.

In general, the disk type feed conveying apparatus feeds the feed in the feed pipe 1 to each feed can 3 by feeding the disk cable 2 into the inside of the feed pipe 1 having an empty pipe shape as shown in Fig. Supply structure. Here, the path of the supply pipe 1 is provided so as to circulate the hopper 4 and each feeding tube 3, and the lower part of the hopper 4 containing the feed is installed so as to pass the feeding pipe 1, To the supply pipe (1). The disk cable 2 is fixed to the wire 2b at regular intervals so that the disk cable 2 moves and feeds the feed in the supply tube 1. [ In addition, a drive unit for moving the disk cable 2 is provided in one section of the supply pipe 1.

The drive unit includes a case having a space therein, a sprocket installed in the case for transferring the disk cable, an auxiliary roller installed at one side of the sprocket to wind the disk cable, and a motor and a speed reducer for supplying power to the sprocket .

The auxiliary roller is provided with tension holding means for sliding the auxiliary roller in a direction opposite to the sprocket while being installed to slide laterally. Here, the tension holding means is provided with a tension spring or the like, one end of which is connected to a bearing for supporting the auxiliary roller, and the other end is connected to the main body so that the auxiliary roller is always pulled away from the sprocket. In addition, an inlet pipe is provided at one end of the main body, and a discharge pipe is provided at the other end. The disk cable introduced from the inlet pipe is wound around the sprocket and the auxiliary roller, and then discharged through the discharge pipe.

Therefore, when the disk cable is stretched due to stagnation of the feed or the like during operation, the auxiliary roller is moved away from the sprocket by the tension holding means, thereby maintaining the tension of the disk cable, and smooth transportation is achieved. A switch for detecting the longest movement of the auxiliary roller is provided at one end of the main body, and when the auxiliary roller is extended for the longest, the buzzers are sounded or the power is shut off to prevent the damage of the disk cable.

However, in such a conventional driving unit, it is troublesome to open the driving unit main body in order to check the degree of increase of the disk cable. In other words, when the disk cable is pulled, the auxiliary roller moves. To confirm this, it is necessary to open the lid of the drive unit main body only after opening the cover, and after confirming, it is necessary to close it again. It takes a long time. There is a problem in that it is impossible to check the state of the disk cable extending in real time due to the inconvenience of opening and closing the cover.

Further, when the switch (control limit) is operated, it can not be confirmed whether the disk cable is stretched or the disk cable is broken without opening the cover. When the disk cable is stretched, the disk cable is frequently restored by restoring the disk cable to the original state, and the disk cable is broken by mistakenly driving the disk cable.
