The control unit 18 can also be attached to the lifting frame 4 or the barrel holding frame 7, in which case the flexible cable 19 will only supply power.

  FIG. 4 is a view showing the configuration of a control device of the transport apparatus, which includes a data input unit 20, a sequence control unit 21, a data tracking unit 22 which is a data tracking function, a program storage unit 23 which is a program storage function, A communication unit 24 is provided. When the conveyance device is an elevator type, the sequence control unit 21 constantizes a series of operations of raising and lowering the elevation beam, rotating the large sprockets 2 and 2 by a constant angle and thereby moving the endless chain 3 by a constant distance and lowering the elevation beam. The operation is performed repeatedly in each cycle. As a result, the columnar carriers 1 are traversed by a constant distance, and the barrel main body 6 supported by the elevating frame 4 via the barrel holding frame 7 is sequentially immersed in each processing tank, and is fixed to the work loaded in the barrel main body 6 Plating treatment is applied.

  The data input unit 20 is for inputting the data of the work loaded in each barrel main body 6 and can be configured by a touch panel or the like, and the input data is sent to the data tracking unit 22. There is no restriction on the place where the control device of this transfer device is installed, and although not shown, it is preferable that the data input unit 20 be installed near the work position where the work is inserted into and loaded into the barrel body 6. The data tracking unit 22 is configured to track data of the work loaded in each barrel main body 6 which is placed in each processing tank according to the operation information of the transfer device given from the sequence control unit 21. The data of the movement of the barrel main body 6 optimum for various different works in each processing tank are previously input and stored.

  As a result, the data of the work loaded in the barrel main body 6 to be taken into a processing tank is obtained from the data tracking unit 22, and the data is used to store the work in the processing tank from the program storage unit 23. It is possible to obtain the data of the movement of the barrel body 6 which is optimal for the above. The data of the program storage unit 23 is given to the communication unit 24, and the communication unit 24 that has received the movement data of the barrel body 6 is sent to the control device 18. FIG. 5 shows the configuration of the control unit 18 which is a control unit of the barrel 5, and comprises a communication unit 25 which is a communication function, a temporary storage control unit 26 and a motor control unit 27. The signal of the sensor 15 is input. The control device 18 is provided to each barrel body 6 respectively.

  The communication unit 25 communicates with the communication unit 24 so as to receive data on the movement of the optimum barrel body 6 with respect to the work loaded in the barrel body 6 and send it to the temporary storage control unit 26. The temporary storage control unit 26 stores the data and sends command values of the rotational direction and rotational speed of the motor 12 to the motor control unit 27 based on the data, and the motor 12 is rotated accordingly and the barrel The main body 6 is rotated. The temporary storage control unit 26 is provided with a timer function, and the command value sent to the motor control unit 27 changes with the passage of time depending on the movement data of the barrel main body 6 stored by the temporary storage control unit 26. Become.

  For example, when changing the rotational speed or the rocking speed halfway, the command value of the rotational speed changes as such at that time, and when stopping the rotation or the rocking, the command value of the rotational speed becomes zero at that time Become. As a result, the motor 12 changes in speed halfway and stops halfway. In addition, when the barrel main body 6 is rocked, the command value in the rotational direction is reversed every predetermined time. Since the motor 12 changes the direction of rotation at predetermined time intervals accordingly, the barrel body 6 will swing, and the angle at which the barrel body 6 swings will be determined by the time interval at which the direction of rotation changes.

  In the barrel plating apparatus of the present invention configured as described above, when the transfer apparatus is an elevator type as in the above embodiment, the elevation of the elevation beam, the large sprocket 2 as in the conventional elevator type plating apparatus A series of rotations of a constant angle 2 and a movement of the endless chain 3 by it and a lowering motion of the elevating beam are repeated at a constant cycle, and the columnar carriers 1 traverse the fixed distance. As a result, the barrel body 6 is repeatedly lifted, traversed, and lowered to be sequentially immersed in the processing solution of each processing tank, and the work loaded in the barrel body 6 is subjected to a predetermined plating process.

  When inserting and loading a work into the barrel main body 6, an operator inputs data of the type of the work from the data input unit 20. The input data is sent to the data tracking unit 22, and the data tracking unit 22 tracks the data of the work loaded in the barrel main body 6 of each barrel 5 which enters each processing tank. In the program storage unit 23, data of optimum movement of the barrel main body 6 in each processing tank is previously input and stored for each type of work. Thus, when it is intended to enter a tank having a barrel main body 6 of a certain barrel 5, data of the type of work loaded in the barrel main body 6 is obtained from the data tracking unit 22. The data of the movement of the barrel main body 6 in the processing tank that is optimum for the work in the work is obtained from the program storage unit 23.

  The movement data of the barrel main body 6 obtained from the program storage unit 23 is given to the temporary storage control unit 26 via the communication unit 24 and the communication unit 25 before the start of the descent of the barrel 5 and stored. When the barrel 5 descends and the barrel main body 6 is immersed in the processing tank, the temporary storage control unit 26 controls the rotational direction and rotational speed command value of the motor 12 based on the stored movement data of the barrel main body 6 Then, the motor 12 is rotated in accordance with the command value. Also, in the case where the rotational speed or the rocking speed changes or the rotation or the rocking stops on the way, the timer value of the temporary storage control unit 26 causes the command value of the rotational speed to be so at that time. Change. As a result, the barrel main body 6 performs an optimum movement in the processing tank with respect to the work loaded in the barrel main body 6.

  At the work position for loading and loading the work into the barrel main body 6, the lid of the opening of the barrel main body 6 is removed and the work is loaded, so the data of movement of the barrel main body 6 stored in the program storage unit 23 is The motor rotates in the forward or reverse direction until it reaches 45 degrees and then stops. Before the start of the descent of the barrel 5, the data is stored in the temporary storage control unit 26 via the communication unit 24 and the communication unit 25. When the barrel 5 is lowered, a command value for rotating the motor 12 forward or backward is sent from the temporary storage control unit 26 to the motor control unit 27, and the motor 12 is rotated according to the command value. When the barrel body 6 rotates and the sensor 15 detects the dog 14, a detection signal is sent to the temporary storage control unit 26, the rotation speed command value becomes zero, and the rotation of the barrel body 6 is stopped. Work can be introduced.

  When the barrel body 6 swings, the timer function of the temporary storage control unit 26 swings by changing the rotational direction of the motor 12 every predetermined time, but the opening of the barrel body 6 Since the sensor 15 detects the dog 14 in the 45-degree direction, it can be detected that the opening of the barrel body 6 is in the 45-degree direction, and the swing angle of the barrel body 6 is shifted. In this case, it can be corrected using this. In addition, the program storage unit 23 stores not only data of movement after the barrel main body 6 is lowered and dipped in the treatment tank, but also data of movement during lifting or lowering of the barrel main body 6. Can. When the barrel body 6 is rotated or rocked during the ascent, there is an advantage that the liquid can be removed more efficiently.

  As described above, according to the barrel plating apparatus of the present invention, the work loaded in each barrel main body 6 to be plated in parallel is processed by each individual barrel main body 6 loaded with the work. Since the tank moves in an optimum manner for the work, even when a plurality of types of work are processed in parallel, optimum stirring is performed, and there is an advantage that the plating finish of all kinds of work is good. In addition, although the conveyance apparatus is made into the elevator type in said embodiment, it can not be overemphasized that it can be set as the conveyance apparatus of other systems, such as a carrier type. When the barrel body 6 is oscillated, the rotation direction of the motor 12 is changed at predetermined time intervals. However, when the barrel body 6 is in the forward and reverse rotational limits of the end plate 8 By providing a dog to be detected in the sensor 15, the rotation direction of the motor 12 can be changed by the detection signal of the sensor 15, and the swing angle can be changed by providing a plurality of dogs.
