Description of the Related Art FIG. 8 is a schematic structural view showing a continuous washing machine proposed in Japanese Utility Model Publication No. 61-1903, FIG. 9 is a perspective view showing a part of the washing machine, and FIG. FIGS. 10 (b) and 11 are explanatory diagrams showing aspects during cleaning, and FIGS. 10 (b) and 11 are explanatory views showing aspects during transfer.

[0003] As shown in FIG. 8, an article to be washed 21 transferred from a charging conveyor C is charged into a stopped drum 1 of a first tank by a charging chute or a hopper H. Detergent and other additives may be added to the first tank together with the article to be washed 21 into the first tank, or may be added to each of the additives or simultaneously by providing an inlet or a valve in either the second tank or the subsequent tank. Good.

In FIG. 8, water flows in from a washing water inlet 17 and flows as a continuous flow at the bottom of each fixed tub 2 ″, 2 ′, 2 and enters a contaminated washing water tank 16.

Thus, at the time of the washing operation, the article to be washed 21 is filled in the plurality of drums 1, 1 ', 1 "connected together with an appropriate amount of detergent and other additives. 1 ″, as shown in FIG.

As described above, the rotation is performed by a unidirectional rotation of at least 270 degrees or more (this unidirectional rotation is referred to as a normal rotation direction, the same applies hereinafter).

[0006] The swing motion of the drums 1, 1 ', 1 "and the rotational motion during transfer are performed by gear mechanisms 13, 13' connected to a motor 15 with a drum drive reduction gear installed outside the drum unit.
The driving is performed by driving a motor 15 with a speed reducer for driving a drum via a transmission clutch mechanism known per se.

At the time of transferring the article to be washed 21 between the adjacent tanks, the transfer scoops 4, 4 ', provided in the drums 1, 1', 1 "
4 "performs a full rotation in at least 270 degrees in one direction. As a result, as shown in FIGS.
The article to be washed 21 is scooped up in the space of each of the drums 1, 1 ', 1 ", passed through the flange portions 11, 12 and transferred to the adjacent drum 1', 1". At this time, the washing water is released from the slits 3, 3 ', 3 "between the scoops 4, 4', 4" and the auxiliary plates 5, 5 ', 5 ".

In the above-mentioned structure, the drums 1, 1 ', 1 "are not oscillated at 270 degrees but in a direction opposite to the rotational direction in which the transfer is performed (this direction is referred to as a reverse direction, the same applies hereinafter).
As shown in FIG. 12, there is a method of performing washing by lifting the object to be washed 21 behind the transfer scoop 4 and causing the object to be washed 21 to fall by continuously rotating the object at a constant number of rotations. In this case, the article to be washed 21 falls only once for one rotation of the drum.

On the other hand, Japanese Patent Publication No. 2-48274 discloses a drum position detecting sensor for swinging a drum of a continuous washing machine at a set angle, and a pulse signal output from the sensor for signal processing. , Is used as the current value indicating the current position of the drum, and when the current value approaches the set value,

In the continuous type washing machine as described above, the machine provided to the object to be washed 21 only by the fir washing action of the object to be washed 21 by the swinging motion of the drums 1, 1 ', 1 ". There is a drawback that the action is small, and it is not possible to clean the object 21 with a large degree of dirt, and that the object 21 is lifted and dropped by scoops 4, 4 ', 4 ". It has been incorporated,
The conventional continuous type washing machine has only a limited washing pattern, and none has a large number of washing patterns that can meet the demands of the user. Therefore, the emergence of an efficient washing facility that can easily change the washing pattern and speed (washing intensity) has been expected.

Further, when the article 21 is transferred, the article 21 is scooped up by the transfer scoops 4, 4 ', 4 "in the space of the drums 1, 1', 1". The washing water contained in the washing 21 flows down from the slits 3, 3 ', 3 "between the scoops 4, 4', 4" and the auxiliary plates 5, 5 ', 5 ". Since 1 "rotates at the same rotational speed as the rocking motion, the draining action at the time of scooping was not sufficiently performed, and there was a problem in cleaning properties and rinsing properties.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

The structure of the continuous water washer described in this embodiment is the same as that of FIG. 8 described in the section of the prior art. Therefore, the part number of FIG. 8 is used as the part number of the main part. That is, 1 is a drum, 4 is a scoop, and 21 is a thing to be washed. Detection and confirmation of the stop position of the rotating drum,
Rotation control such as position correction is performed by detecting teeth of a large gear that is mounted on the drum and coaxial with the rotation axis of the drum, as disclosed in Japanese Patent Publication No. 2-48274. A method of detecting the rotation angle and the rotation direction of the drum, sending a signal to the control device, and starting and stopping the drum, correcting the rotation angle, and the like is applied.

FIG. 1 is a block diagram showing an operation control device according to this embodiment. As shown in the figure, a CPU 31 is a microcomputer unit, which is the center of control of a continuous washing machine,
A ROM (read only memory) 32 is a storage unit for storing a cleaning pattern, a cleaning speed, a control order, and the like, a RAM (write memory) 33 is a storage unit for temporarily storing data necessary for control, and a power failure protection 34 is RAM when power is turned off
Since the storage contents of 33 are lost, a battery for backing up the data, an output circuit 35 sends a signal for operating the speed of the variable speed motor control device 39 and operating the valve and the pump 41, and an input circuit 36 for the drum The control input / output IO interface 37 sends a control signal from the CPU 31 to the output circuit 35. The control input / output IO interface 37 receives a signal from the proximity switch 42, which is a rotation position detection sensor, and an external signal generator IV for switching a washing pattern and a washing speed. In addition, an interface for transmitting a signal supplied from the input circuit 36 to the CPU 31, and a panel control IO interface 38 is an interface for transmitting and receiving signals between the operation panel III and the CPU 31.

The continuous washing machine has the same structure as that shown in FIG. 8 as described above.
Is formed by, for example, a variable speed motor which is an induction motor with a speed reducer, and has a proximity switch 42 for detecting the rotational phase of the drum. The rotation speed of the drum motor 40 is controlled by frequency control by an inverter of the variable speed motor control device 39. The valve and the pump 41 are valves and pumps for washing water and rinsing water, and have exactly the same configuration as the conventional one.

The control unit I includes the CPU 31, the P-RO
M32, RAM 33, power failure protection 34, output circuit 35, input circuit 36, control input / output IO interface 37, and panel control IO interface 38.

The operation section III is for manually setting a cleaning pattern and a cleaning speed. FIG. 2 shows an example of a display on the operation panel. As shown in the drawing, the digital switch 43 on the left side indicates the number of times of washing and counts the number of reciprocating swings as one. Two rotary switches 4
Out of 4, 45, the left side is a switch for selecting a washing pattern, and the right side is a switch for selecting a washing speed (washing intensity).

FIG. 3 is a circuit diagram showing an electric circuit of the operation unit III. As shown in the figure, in the case of the automatic operation, the washing pattern and the washing speed are changed according to the washing condition of the article 21 to be washed which is input to the main operation unit IV of the washing facility other than the operation unit III.
It is input here as an external signal. The output of the relay of the operation unit III is transmitted to the CPU 31 via the panel control IO interface 38 of FIG. The cleaning pattern selected in the operation section III, and commands for the washing speed and the number of swings are also transmitted to the CPU via the operation relay in the operation section III and the panel control IO interface 38.

The CPU 31 retrieves the operation data of the cleaning pattern instructed from the P-ROM 32, confirms the rotation phase of the drum 1 based on the signal from the proximity switch 42, passes through the control input / output IO interface 37, and the output circuit 35. By operating the variable speed motor control device 39 to control the drum motor 40, a predetermined cleaning pattern is realized. Further, by automatically switching the rotary switches 44 and 45 of the operation unit III, the cleaning pattern determined by the type and condition of the article 21 can be automatically selected by an external signal.

Next, an operation pattern of the drum 1 when the washing object 21 is washed by the continuous washing machine will be described.
