This pine surge machine has pine surge functions such as stretching the back of the sushi, raising and lowering the sushi by operating the fir ball 11, and its control device is constructed as shown in FIG. This control device includes various sensors 26, 27, and 32 in an electronic control circuit 33 with a built-in microcomputer.
, each M operation key 34, storage key 35, motor 9, solenoid 20, etc. are connected. The electronic control circuit 33 includes a main processing means 36 that automatically or manually processes various pine surge functions according to commands from the operation keys 34, and a control means 37 that checks the operation of the fir ball 11 according to each pine surge function. and a storage control means 38 for storing the fir balls 11 at the lower limit position and at the expanded □- position where the distance between the pair of fir balls 11 and 11 is at its maximum after the pine surge operation is completed.

The storage control means 38 automatically stores the fir balls 11 after the automatic mode ends during automatic operation, and
During manual operation using the operation key 34, the fir ball 11 is operated to be stored using key power from the storage key 35. Therefore, in this pine surge machine, after the pine surge operation is finished, the fir ball 11 is always placed on the backrest l.
The left and right fir balls 11.
It stops at the expanded position of 11.

Next, the operation will be explained with reference to the flowcharts shown in FIGS. 5 to 7. The pine surge machine usually performs the pine surge operation by using a pair of left and right fir balls 11 to perform a fir ball operation for lengthening the spine or for raising and shortening the fir. However, when using it as a chair after the mansage operation is finished, the fir balls 11 get in the way, so lower the fir balls 11 to the lower limit position, turn it around front and back, and use the backrest! Store it in a retracted position at the rear of the interior.

Control at this time is performed by the storage control means 38 according to the fir ball storage program.

That is, in the case of the automatic course, control is performed according to the stop program of the main processing means 36. Determine whether the automatic course timer is starting in step ■ in Figure 5, and press YES.
If S, the process returns to the main processing program in step (2) and continues the pine surge operation. If No, the pine surge operation has ended, so the automatic pine surge end buzzer is activated (step ■), and the vertical movement stop processing command (step ■) and the horizontal movement stop processing command (step ■) are sequentially issued. After that, the fir operation position check command (step ■) is issued.At this time, the fir ball check program shown in FIG. ), and if it is stored, return the confirmation command to step ■ and move on to the termination processing command (step ■),
After tIt, issue the end buzzer timer count command (step ■), end buzzer command (step @), and program end command (step ■) in sequence, and return to the main processing (
Step @).

When the storage key 35 is operated, the key manual buzzer command (step @) and vertical movement stop processing command (step [phase]) are issued, as shown in FIG. , motor stop processing command (step ■
), fir movement processing command (step @), and fir movement stop processing command (step @), it is determined in step ■ whether the storage operation is in progress. If YES, the fir ball position check command is issued as shown in FIG. (Step [phase]). At this time, if the fir ball 11 is in the predetermined position, the recognized command is returned to step 0 and a storage completion command is issued. After issuing a cancel command to all timers upon completion, return to main processing (step [phase]).

During the momi check, the program shown in FIG. 7 is followed. That is, in the stop program of the automatic course (main process) or the storage program manually operated with the storage key, if the storage key progresses to the fir check, the storage operation and storage confirmation operation of the fir ball 11 are performed in the fir check program. First, in step (3). , it is determined whether the position of the fir ball 11 is in the fixed position stop operation. At this time, stopping at a fixed position refers to a state in which the fir balls 11 are protruded to the front side.

Since the pine surge operation ends when the fir ball 11 is stopped at a fixed position, if the fixed position stop operation is in progress, it is determined in step 0 whether the storage operation is in progress. And the judgment in step @ is Y
If it is ES, the mogo ball moves in the forward rotation direction (step 0)
In the case of No, the fir ball moves in the reverse direction (step o). In step 0, it is determined whether the sensing of the position sensor 32 at the fir ball storage position is OK. If YES at this time, then it is determined whether the timing monitoring of the position sensor catch is OK, that is, whether the time-up monitoring is OK (
step @), if the determination at step 0 is No, A
Proceed the program in the direction. This is a case where the ball storage position cannot be detected by the position sensor 32. If YES in step [phase], a command to rotate the fir ball is issued in step [phase].

Also, if No in step ①, the program progresses in the direction of normal rotation of the fir ball and issues a rotation command for the fir ball 11 (step @), and if YES, the process returns to step 0.
In the confirmation program, proceed again in the order of step O → step @ → step ■. If the answer is NO at step 0, or if the answer is NO at step [phase], the process returns to step O. When the fir ball 11 rotates forward according to the command in step [phase], the fir ball 11 is stopped in the stowed position, and the fir ball brake timer is set and Issue a stop command (step O), pass through step [phase], issue an ON command to the fir ball brake (step [phase]), and completely stop the fir ball II at the storage position by the fir ball brake. If the fir ball H can be stored, the fir ball brake can be turned off after a certain period of time.
A command to turn the FF is issued (step 0). This completes all the storage operations of the fir ball 11, so the process is returned to the initial program (main processing program) (step 0), and the motor 10 and solenoid 20 are Issue an OFF command (step O), and at the same time return to the main processing program, issue a fir check OK command to the main processing program (step @). When you return to the main process, check the fir ball position in step (2) in the stop program of the automatic course. Issue an OK command.

When the program progresses in the direction from step O, that is, when the storage position of the fir ball 11 cannot be detected by the position sensor 32 and the determination at step [phase] is No, proceed to step [phase]. The same applies when the judgment in (2) is No. In step [phase], it is determined whether the timer of the fir ball brake is counting. And Y
If it is ES, it passes through step ■[phase][phase] and then returns to N.
If O, turn on the fir ball brake (step [phase]).

(Effects of the Invention) According to the present invention, the fir ball storage control means 38 is provided for storing the fir balls 11 at the lower end position and the maximum (expanded) mutual spacing position after the pine surge operation. After finishing, the fir tree balls 11 will definitely descend, expand and stop, so the fir tree balls 11 will not get in the way even when used simply as a chair.
