Description

[Detailed explanation of the invention] (a) Industrial application field This invention is based on the idea that a cage-shaped container such as a rectangular or rectangular container for commercial use is placed on a horizontally rotating box frame-type turntable, and The present invention relates to an improvement in an automatic container jet washer that cleans containers by spraying cleaning liquid pressure toward the containers from left and right.

(b) Conventional technology Conventionally, in this type of automatic container jet washer, containers are placed on a box frame-type turntable with the opening facing downward, and this single container is exposed to water pressure from the upper surface of the bottom wall. Supported under pressure by a cylinder via a pusher,
A device in which containers are rotated horizontally by a turntable and cleaned by spraying pressure of cleaning liquid from the top, bottom, left and right directions is disclosed in Japanese Utility Model Publication No. 1983-7828 filed by the same applicant as this applicant. has been disclosed.

(c) Problems to be solved by the invention By the way, in the case of such a container jet washer, a single container is placed on a turntable with the opening facing downward, and this container is pressed from above. The turntable is supported under pressure by the turntable, and is designed to withstand the high-pressure cleaning liquid pressure from the cleaning nozzle that sprays from below toward the entire inside of the container. There is a risk that the container on the turntable may slide and swing outward due to the lubricating action of the cleaning liquid acting on the container support surface of the turntable.

Furthermore, since the containers are placed one by one on the turntable and cleaned, there is a drawback that the efficiency of continuous cleaning of a large number of containers is reduced. Therefore, it is of utmost importance that the containers placed on the turntable be held immovably and thoroughly cleaned during cleaning. Additionally, it is most necessary to efficiently and thoroughly clean and clean a large number of containers.

(d) Technical means to solve the problem This invention, as a technical means to solve the above-mentioned problem, consists of installing rotating cleaning liquid spray nozzles 2a and 2b in the center of the cleaning chamber in the machine box 1. A cleaning liquid feeding rotating main pipe 3 is installed almost vertically, and a container C to be cleaned is placed on both left and right sides of a frame-shaped turntable 4 which rotates horizontally by rotation of this liquid feeding rotating main pipe 3, and its opening is connected to the liquid feeding rotating main pipe. Arm-shaped press bars 5 and 6 are attached to the turntable 4 to form a storage part T that is placed upright facing the rotating spray nozzle 3, and to press and hold this container C from the back to the center of the frame-shaped turntable 4. It is set to operate via the ramrods 8 and 9 of the power cylinder 7, which is powered by the cleaning liquid pressure installed at the upper center of the cylinder.

(e) Action First, open the opening _/ closing door 10 installed in the front of the machine box 1 so as to be able to move up and down, for example, and as shown in Fig. The opening/closing door 10 is placed on both sides of the frame-shaped turntable 4 facing the liquid feeding rotation main pipe 3 of the section.
After closing, turn the operation start switch on the operation panel 11.
The ON operation drives the cleaning liquid feed pump P ₁ to forcefully feed the cleaning liquid in the cleaning liquid tank through the main liquid feeding pipe 12 to the left and right branch liquid feeding pipes 13 and 14, and the cleaning liquid from the right branch liquid feeding pipe 14 is sent almost vertically. The cleaning liquid is pumped into the vertical liquid feeding pipe 15 which is raised and connected, and this cleaning liquid is fed under pressure into the upper liquid feeding pipe 16. and,
The cleaning liquid is force-fed through the upper liquid-feeding pipe 16 to a cap-type liquid-feeding head 17, and from there to a liquid-feeding pipe 18 that is sealed-fitted to the liquid-feeding head 17 so as to be horizontally rotatable. The cleaning liquid from this liquid sending pipe 18 is fed under pressure to the central hydraulic chamber 20 of the power cylinder 7 by a hydraulic cylinder or the like connected horizontally to the upper central member 19 of the frame-type turntable 4, and the hydraulic pressure causes the tension coil spring to The left and right rams 23, 2 are restored by the elastic restoring force of 21, 22.
4 are slid in opposite directions or outwardly from each other, thereby forcing the ramrods 8, 9 outwardly. The ram rods 8 and 9 actuate connecting levers 27 and 28 hinged to the outer ends of the upper member 19 of the frame-type turntable 4 with pins 25 and 26, respectively, to operate the arm-type bars 5 and 6. The lower end is pushed inward, and the tip parts 29 and 30 are used to forcefully push the back side of the container C.
The peripheral edge of the opening is brought into pressure contact with the vertical members 31 and 32 at the center of the frame-shaped turntable 4, so that the container C is immovably held in the accommodating part T of the frame-shaped turntable 4. At the same time, on the other hand, the cleaning liquid that has been force-fed to the left and right branch liquid-feeding pipes 13 is force-fed to the liquid-feeding rotating main pipe 3 and flows upward, and is force-fed to the rotating injection nozzles 2a and 2b, and the cleaning liquid is pumped into the container. It is designed to powerfully spray in a radial direction toward the entire inner circumferential surface of C. At the same time, the start switch of the drive motor M on the operation panel 11 is turned ON to drive the drive motor M, thereby starting the sprocket 33, the transmission chain 34, and the sprocket 35.
is rotated to rotate the rotating shaft 36, thereby rotating the liquid feeding rotary main pipe 3 at a relatively low speed, and thereby, as shown in FIG. Rotating the large diameter bevel gear 38 fixed to the rotating main pipe 3, meshing with it to rotate the small diameter bevel gear 40 fixed to the horizontal rotating shaft 39, and rotating the transmission sprocket 41 fixed to the other side of the rotating shaft 40, From this, an upper sprocket 43 is rotated via a transmission chain 42.

The rotating tube shaft 44 of this sprocket 43 is connected to the first
As shown in FIG. 0, it is supported horizontally on a bearing part 45 at the upper part of the liquid feeding rotational main pipe 3 and is formed integrally with the bearing part 45 through a cleaning liquid discharge opening 46 in the upper part of the liquid feeding rotational main pipe 3. Since pressure inlets 49 and 50 for the cleaning liquid are provided in the surrounding wall 47,
The cleaning liquid press-fitted from the press-fitting chamber 48 is press-fitted into the rotary tube shaft 44 through the press-in ports 49 and 50, and is then fitted and fixed into the press-fit openings 51 and 52 opened at both left and right ends of the rotary tube shaft 44. The rotary jet nozzles 2 are press-fitted into the rotary jet nozzles 2a and 2b, and the rotary jet nozzles 2
A, 2b are rotated in a manner similar to the rotating state of a water wheel, and the cleaning liquid is injected radially.Furthermore, the liquid feeding rotation main pipe 3 is rotated horizontally, and the cleaning liquid is sprayed from the rotating injection nozzles 2a, 2b into a frame. By the horizontal rotation of the mold turntable 4, a powerful and concentrated injection is made from the opening of the rotating container C toward the entire inner circumferential surface to completely clean the inner circumferential surface of the container C.

On the other hand, the eccentric disk 53 is rotated by the horizontal rotating shaft 39 in synchronization with the cleaning movement of the container C, and the crank rod 54 eccentrically pin-hinged thereto is moved back and forth in a predetermined stroke, as shown in FIGS. 3 and 4. Crank rod 5 as shown in the figure.
A lever 56 hinged with a pin 55 at the tip of the flange-type bearing 5 is fitted and fixed to a forward/reverse rotary tube shaft 57 that is sealed through the branch liquid feeding pipe 13 on the left side.
The rotary tube shaft 57 is freely rotated in forward and reverse directions through the inner circumferential bushes 60 and 61 of 8 and 59, and a plurality of oscillating shafts are provided with open and communicating openings at both left and right ends of the rotary tube shaft 57. A rotating tube shaft 57 that rotates the reverse rotating nozzles 62 and 63 in forward and reverse directions at rotational speeds of 30R, P, and M, for example.
While rotating forward and backward in an oscillating manner, the high-pressure cleaning liquid injected from the liquid feeding pipe 13 is concentratedly sprayed in a fan shape toward the lower surface of the container C, which is rotating horizontally on the frame-shaped turntable 4. The lower surface of C is completely cleaned.

In synchronization with the injection operation of the cleaning liquid by the forward and reverse rotating nozzles 62 and 63, the right branch liquid feeding pipe 14 is connected to the vertical liquid feeding pipe 15 and the liquid feeding upper pipe 16.
A forward/reverse rotating nozzle 6 having the same configuration as the above-mentioned forward/reverse rotating nozzles 62, 63 which oscillates and is provided in communication with these liquid feeding pipes to send the high pressure cleaning liquid under pressure to the
4, 65, and 66, the frame-shaped turntable 4 sprays powerfully toward the back and upper circumferential surfaces of the container C, which is rotating horizontally, to completely clean it.

Then, the high-pressure cleaning liquid from the upper liquid sending pipe 16 is forced through the connecting pipe 67 to the liquid sending head 17, and from there, through the opening 68 to the horizontally rotating vertical liquid sending pipe 18 connected to the lower part. High-pressure cleaning liquid from the pipe 18 is pressurized into the central hydraulic chamber 20 of the power cylinder 7, and this liquid pressure pushes the left and right rams 23, 24 outward in opposite directions, and at the same time pushes the ram rods 8, 9 outward. Let's advance. The ramrods 8, 9 push the enecting levers 27, 28 outward and at the same time push the press bars 5, 6 toward the back of the container C, and the tips 29, 30 forcefully push the back of the container C. The opening Op of the container C is pressed against the central vertical members 31 and 32 of the turntable 4 to immovably fix the container C on the turntable 4.

Therefore, the container C does not swing due to the rotational centrifugal force caused by the horizontal rotation of the power cylinder 7, the ram rods 8, 9, and the press bars 5, 6, which rotate horizontally at the same time as the turntable 4, and the rotating injection nozzle 2
a, 2b, lower and side parts that swing and rotate, and forward and reverse rotating nozzles 62, 63, 64, 65,
By spraying high-pressure cleaning liquid from the container 66, the entire inner and outer surfaces of the container C, which is fixed on the turntable 4 and rotates horizontally, are completely washed with high efficiency and cleaned in a short time.

For final cleaning (rinsing) of the container C housed and fixed in the housing part T of the frame-type turntable 4, a finishing cleaning liquid such as hot water or water is passed from the liquid sending pipe _P2 to the liquid sending pipe 69 to the other side of the machine box 1. The main pipe 70 for cleaning is installed vertically, from which it is sent under pressure to upper and lower branched finishing cleaning pipes 71 and 72, and then to the vertical cleaning pipe 73 installed near the rotating main pipe 3. These cleaning nozzles 74, 75, 76, and 77 powerfully and intensively spray the finishing cleaning liquid toward the entire inner and outer periphery of the container C to completely perform the finishing cleaning.

(f) Example of implementation of the idea Examples of this invention will be described below.

Reference numeral 1 denotes a machine box with an opening/closing door 10 installed on the front, and a rotating injection nozzle 2 at the upper part approximately in the center of the box.
The liquid feeding rotating main pipe 3 in which pipes a and 2b are installed is supported substantially vertically by a lower bearing member 37 so as to be horizontally rotatable. A sprocket 41 is attached to a horizontal rotating shaft 39 of a small diameter bevel gear 40 that is meshed with a large diameter bevel gear 38 fixed to the lower part of the liquid feeding rotation main pipe 3.
The eccentric disc 53 is fixed, and the rotation of the sprocket 41 is transmitted through the transmission chain 42 to the sprocket 43 fixed to one end of the rotating tube shaft 44 of the upper rotating injection nozzles 2a, 2b. There is. The rotary tube shaft 44 is supported by a bearing 45 that forms a surrounding wall 47 at the upper part of the liquid feeding rotary main tube 3, and rotary injection nozzles 2a and 2b are fitted and fixed on both sides. As shown in FIGS. 10 and 11, the high-pressure cleaning liquid is supplied to these rotary injection nozzles from the liquid feeding rotary main pipe 3 through the discharge opening 46 and the press-in chamber 48 and from the pressure inlets 49 and 50 to the rotary pipe shaft 44.
At the same time, the high-pressure cleaning liquid is sent from the press-fit openings 51 and 52 to the rotary spray nozzles 2a and 2b, and the high-pressure cleaning liquid is powerfully and intensively sprayed from the rotary spray nozzles 2a and 2b toward the entire inner circumference of the container C to completely clean the container. It is becoming more common to do so.

Horizontal rotation of the liquid feeding rotation main pipe 3 is performed by rotating a rotary shaft 36 from a sprocket 33 via a transmission chain 35 to a sprocket 34 by a motor M installed at the lower part of the machine box 1.

The high-pressure cleaning liquid is supplied to the liquid feeding rotation main pipe 3 by a cleaning liquid feeding pump P ₁ installed at the bottom of the machine box 1.
The liquid is passed through the main liquid feeding pipe 12 through the opening at the left end of the branched liquid feeding pipe 13, and then through the opening 78 provided at the lower part of the main liquid feeding rotating main pipe 3.

The high-pressure cleaning liquid from the main liquid feeding pipe 12 is sent from the branch liquid feeding pipe 14 on the right side to the vertical liquid feeding pipe 15 connected via an elbow 80, and from this to the upper liquid feeding pipe 16 connected via an elbow 87. The cleaning liquid is then forced into the central liquid receiving chamber 20 of the power cylinder 7 through the liquid sending head 17 and the liquid sending pipe 18 by the cleaning liquid pressure.

The frame-type turntable 4 on which the container to be cleaned C is placed and held is connected to a flange F provided at the upper part of the liquid feeding rotation main pipe 3.
The power cylinder 7 is firmly connected and fixed to the upper horizontal member 19 via a horizontal mounting member S provided at the center thereof, and the power cylinder 7 is firmly and horizontally connected to the upper horizontal member 19. Pressing levers 5 and 6 and connecting levers 27 and 28 are pivotally mounted on both left and right sides of the upper horizontal member 19 of the turntable 4 by pins 25 and 26.
Furthermore, a lever 56 whose tip is pivotally connected to the left and right sides of the turntable 4 by a pin 55 is inserted into the left branch liquid feeding pipe 13 at right angles via a bearing 58 and a bush 59, and is sealed as a forward and reverse rotating tube. It is fixed to one end of the shaft 57, and forward and reverse rotation nozzles 62 and 63 are connected to both left and right ends of the rotary tube shaft 57 with their lower openings communicating with each other, and the lever 56 rotates the rotary tube shaft 57 in the forward and reverse directions. I'm starting to let them do it. During this forward and reverse rotation movement of the forward and reverse rotation nozzle, the high-pressure cleaning liquid from the branched liquid feeding pipe 13 is introduced into the rotary tube shaft 57 through the introduction ports 60 and 61 opened at the center thereof, and this cleaning liquid is transferred to the forward and reverse rotation nozzle. 62,6
3, and this high-pressure cleaning liquid is sprayed all over the lower circumference of the container C to clean it.

The structure of the forward and reverse rotation nozzles 62 and 63 and the jetting action of the high pressure cleaning liquid are the same as those of the forward and reverse rotation nozzles 64, 65 and 66 shown in FIG. The forward and reverse rotational motion of these forward and reverse rotation nozzles is caused by the movement of the levers 86 and 87 by the forward and backward reciprocating motion of the vertical reciprocating rod 82 via a bell crank 81 pivoted to the elbow 80 from the lower reciprocating rod 79. The lever 88 is smoothly moved by the upper reciprocating rod 91 via a bell crank 90 pivotally connected to the elbow 89.

The hydraulic pressure of the power cylinder 7 pushes the ram rods 8 and 9 outward, thereby applying the pressing force of the container C to the pressing bars 5 and 6, and immobilizing the container C on the frame-shaped turntable 4. The functions held in this are as described above. In the movement of the ram rods 8 and 9 back and forth by the energy of the power cylinder 7 as a pressure source for the pressure levers 5 and 6, as shown in FIGS. 6 and 7, both ends of the tension coil springs 21 and 22 are A connecting rod 9 supports the upper parts of the connecting levers 27 and 28 on pivot members 92 and 93 provided at the outer ends of the ram rods 8 and 9.

Also, pin 2 of connecting levers 27 and 28
The upper ends of the press bars 5, 6 are fitted and fixed to both ends of the bars 5, 26. Furthermore, horizontal stays 98 and 99 are provided at both ends of the support shafts 25 and 26 to firmly hold the support shafts in a horizontal state.
101 is installed.

(g) Effects of the device As mentioned above, this device installs a rotating main pipe for feeding the cleaning liquid almost vertically, with a rotating spray nozzle for the cleaning liquid installed almost in the center of the cleaning chamber of the container to be cleaned. A housing part for holding the container to be cleaned upright with its opening facing the rotary spray nozzle is formed on the left and right sides of the frame-type turntable that is connected to the main rotating pipe and rotates horizontally. The rotary spray cleaning liquid can be powerfully and concentratedly sprayed from the opening of the container all over the inner periphery for complete cleaning.

Furthermore, the container to be cleaned placed and housed in the housing part of the frame-shaped turntable is strongly pressed from the back side by the pressure bar by the pressing force of the hydraulic power cylinder and is firmly held in the housing part. The rotary centrifugal force of the turntable keeps it seated and fixed in place until the cleaning is completed without any movement, and the cleaning nozzle powerfully sprays the cleaning liquid from the top and bottom sides onto the entire top, bottom, and back of the container, covering the entire container. Can be completely cleaned in a short time. Therefore, it has an excellent cleaning function as an automatic container jet washer and has great practical effects.
