In particular, the annular groove 51 and the narrow portion 52 is formed at the lower end of the support bar 50 so that the annular groove 51 and the narrow portion 52 can be easily inserted into the can 2 and beaded. By the recess 51, the beading was made easier.

The operation relationship will be described below. As shown in FIG. 4, the operation is started in a state in which the supporting rod 50 is upward. Can stopper 26, the can (2) being transported along a feed guide 22 by the operation of the feed conveyor 21 in the opened state is when passing through the sensor (S ₁₎ which passes through the sensor (S ₁₎ (2) is sensed and the stopper 26 is operated to stop the trailing can 2 from being transferred.

The can 2 passing through the sensor S ₁ is introduced into the induction guide 25 and the index motor 27 is operated to rotate the index table 28 by a predetermined angle. The can 2 to be transported when the index table 28 is rotated is introduced into the settling groove 28-1 of the index table 28 and then moves along the guide guide 25.

After the index table 28 is stopped, the motor 31 is operated. Before the motor 31 is operated, the cam 35 is in a state in which the roller 40 abuts on the lower surface 36-2 and the cam 36 is in contact. ) Is a state in which the roller 46 is abutted on the high surface 36-1 so that each bead ring plate 42 and 48 is spaced apart from the can 2, that is, the can 2 to be conveyed is spaced apart. It is introduced between the round plates 42 and 48 to be stopped.

In this state, the motor 31 is operated.

The rotary shafts 32 and 33 are rotated by the operation of the motor 31. When the rotary shaft 32 is rotated, the cam 37 is rotated and the lower driving surface 37-2 and the lower driving surface 37-2. The roller 58 which was in contact with the upper surface is lowered while being in contact with the high running surface 37-2 as shown in FIG. 7. With the roller 58, the lifting bar 54 is downward while compressing the spring 56. When the lifting bar 54 is downward, the interlocking gear 53 and the support bar 50 are also downward, and the support bar 50 is Its lower end is inserted into the top of the can 2.

On the other hand, when the lower rotary shaft 33 is rotated, the drive gear 34 and the cam 35, 36 is rotated.

The interlocking gear 53 engaged with the drive gear 34 by the rotation of the driving gear 34 is connected to the elevating rod 54 with the children 53-1, so that the interlocking gear 53 rotates regardless of the elevating rod 54 in the stationary state. It is done. When the interlocking gear 53 is rotated, the support bar 50 inserted into the can 2 is rotated to rotate the can 2.

In addition, when the cams 35 and 36 are rotated by the rotation of the rotary shaft 33, the roller 40 on the lower surface 35-2 of the cam 35 is supported by the high surface 35-1. The operation section 38 rotates the shaft 39 from the starting point to bring the bead ring plate 42 close to the can 2 being rotated, and the roller 46 on the high side 36-1 of the cam 36 is rotated. ) Is located on the lower surface 36-2 to be rotated, so that the operation section 44 is moved outwardly from the axis 45 and closes the bead ring plate 48 to the can 2 that is rotated. .

As described above, the can 2 is rotated by the support rod 50 which is downwardly and rotated by the operation of the motor 31, and the beading plate 42 and 48 are brought into contact with the can 2. Since the annular groove 51 is formed at the lower end of the support bar 50, the beading portion 3 of the can 2, which is to be beaded by the bead ring plate 42 and 48, may be easily beaded.

After the beading is completed, as shown in FIG. 4, when the low running surface 37-2 of the cam 37 returns to its original state, the interlocking gear together with the elevating bar 54 by the elastic force of the spring 56 is returned. 53 and the support bar 50 is raised and the cam 35 and the cam 36 is the lower surface (35-2) and the high surface (36-1) is to support the rollers (40, 46) The bead ring plates 42 and 48, which are in contact with the can 2, are spaced apart from each other.

As such, when the supporting rod 50 is raised and the bead ring plates 42 and 48 are spaced apart from each other, the operation of the motor 31 is immediately stopped. At the same time, the stopper 26 is opened while the index motor 27 is operated to index. Rotate the table 28.

When the can 2 passes through the sensor S ₁ , the stopper 26 operates to stop the supply of the trailing can 2, and the can 2 introduced into the induction guide 25 is rotated through an index table ( The can 2 on which the beading to be settled in the settling groove 28-1 of 28 is rotated along with the index table 28.

After the rotation is completed, the beading device 20 according to the present invention is repeated the above process.

When the above-described series of processes are repeatedly and continuously carried out, the can 2 after the beading is completed is transferred to the next process through the discharge conveyor 23.

As described above, according to the present invention, the can being conveyed by the feed conveyor is transferred to the index table which is intermittently rotated, and the can introduced into the index table is subjected to the next step through the discharge conveyor after the beading is performed. Since a series of processes to be transferred are automatically performed, the beading time is shortened and the efficiency is improved. As the beading state is made uniform, the reliability of the quality is improved and the productivity is improved by the continuous operation by the cam drive method. Not only that, but also a series of processes are automatic, so they can be adopted and used in the automated production line of the product.

In addition, by allowing the beading device to be operated by a single power source in addition to the power source that operates the index table intermittently, it is possible to reduce the manufacturing cost of mass production.
