Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work cleaning device and a work drying device, and in particular, occupies an installation space as much as possible at a work site for so-called works such as a baking sheet and a baking sheet to be placed when baking bread and cakes. The present invention relates to a work cleaning device and a work drying device that are suitable for quick cleaning and drying without performing the cleaning.

[0002]

2. Description of the Related Art Conventionally, foods such as bread and cake are
The dough is put in a tray-shaped container called a top plate and baked. When baking with this top plate, edible oil is applied to the surface on which the object to be baked is placed as a release material, but when baked at high temperature, the baking scraps of bread and cake stick to the top plate and stick to it. Will end up. Such stains on the burned scraps are difficult to remove and the number of them is large, so it is a labor-intensive and time-consuming operation depending on human hands. Therefore, various automatic cleaning devices for automatically cleaning the top plate have been proposed.

For example, Japanese Patent Application Laid-Open No. 5-316919 proposes a food baking top plate cleaner for making a large working space large (see Patent Document 1). This food baking baking sheet cleaner brings a cleaning brush made of elastic synthetic resin into contact with the bottom surface of the conveyed baking sheet, the inner surface of the side plate and the corners, and removes stains on the baking sheet by the rotating force of the cleaning brush. To do. A roller for supplying cooking oil is also provided on the bottom surface of the top plate, and it is said that a substantial working space can be obtained by implementing the top plate cleaning and refueling with one device.

On the other hand, Japanese Patent Laid-Open No. 5-64537 discloses that
For the purpose of cleaning a tray-shaped top plate with the posture facing upward, a top plate cleaning machine that jets air and a high-pressure water stream has been proposed (see Patent Document 2). In this washing machine, an air jetting means and a high-pressure water jet jetting means are provided so as to enter from a direction opposite to the carrying direction in the carrying path of the top plate. Then, the cleaning liquid ejected from the cleaning water ejecting means and applied to the top plate is blown off by air so as not to collect. As a result, the water pressure cleaning effect is not reduced by the accumulated water on the top plate, there is no need to reverse the top plate in order to drain the accumulated water, and the top plate can be washed with the top position facing upward. It is supposed to be possible.

[0006]

However, in the invention disclosed in the above-mentioned Japanese Patent Laid-Open No. 5-316919, the rotating cleaning brush is brought into contact with the top plate while the top plate is directed upward to remove the adhered matter. Since it is only peeled off, the scraps scraped off by the cleaning brush may not be completely removed and may remain on the top plate. Further, since the cleaning brush is always in contact with the top plate at the same position and at the same angle, there is a difference in how dirt is removed, and since no cleaning liquid is used, some dirt cannot be removed depending on the type.

On the other hand, in the invention described in the above-mentioned Japanese Patent Laid-Open No. 5-64537, a detergent water jetting means, an air jetting means, a high pressure water jetting means, a rinsing means, a drying means and the like are sequentially provided in the carrying direction. Therefore, the length of the entire device in the carrying direction is inevitably long. Therefore, a large space must be secured in order to install such a top cleaning machine. Generally, a bakery factory is equipped with a top plate cleaning device and a drying device so that the top plate after baking can be quickly washed and dried to be used for the next baking. In order to improve the productivity, it is necessary to make the space of the bread manufacturing device large and the space of the top plate cleaning device and the drying device unrelated to the production as small as possible, which is also the user's need. Further, in the above-mentioned washing machine, the jetting angle of the high-pressure water stream with respect to the top plate does not change and is always constant, so that the stains on the top plate may be uneven.

In order to enhance the cleaning power in the above-described cleaning apparatus, generally, it is sufficient to invert the object to be cleaned or the like so that the cleaning liquid is contacted with the cleaning liquid from various angles, or to increase the cleaning time. Therefore, in order to increase the cleaning time, it is conceivable to reduce the transportation speed of the object to be cleaned, but this is not preferable because the number of cleanings per unit time decreases. On the other hand, in order to secure the cleaning time without slowing down the transportation speed of the object to be cleaned, it is conceivable to extend the transportation distance to extend the cleaning distance, but the arrangement space of the cleaning device becomes large.

Further, in such a cleaning device, a drying device for drying the object to be cleaned after cleaning may be additionally provided. This drying device also has the same problems as those of the above-mentioned cleaning device. For example, there is a problem of a layout space that requires a long drying distance in order to sufficiently dry the top plate and a corner portion of the top plate. There is a problem of dry quality and efficiency that it is difficult to dry the water.

The present invention has been made in order to solve such a problem, and can save the installation space without reducing the number of washed and dried works per unit time and can be simplified. It is possible to increase the number of washings and the number of dryings. Moreover, since the cleaning liquid and the drying air can be applied from various angles while the work is rotating or stopped, it is possible to eliminate uneven washings and uneven dryings for efficient washing and drying. It is an object of the present invention to provide a work cleaning device and a work drying device capable of performing.

Further, in the first embodiment, a sensor (not shown) that detects the rotation angle of the rotating body 8e is provided, and it is detected that the rotating body 8e rotates every 90 degrees. Alternatively, the rotation angle of the rotating body 8e is converted into the number of steps of the motor, and the stop control is performed according to the number of steps to perform the stop control of the rotating body 8e every 90 degrees. Therefore, when rotating the rotating body 8e, the driving force of the motor is transmitted from the clutch to the driving sprocket and is transmitted to the rotating sprocket 8b1 via the drive chain. The sensor is the rotating body 8
When the 90 degree rotation of e is detected, the clutch is disengaged while the motor 8f is still rotating to interrupt the power transmission, and the brake immediately stops the rotation of the drive sprocket and the rotation body 8e is stopped and controlled. It has become.

The support frame 8c has a substantially rectangular parallelepiped shape, and the surface attached to the bearing 8b is formed by a square frame plate 8c1. Further, four frame rods 8c2 are extended and connected between the both frame plates 8c1. In this way, the support frame 8c
Has a minimum skeleton structure, and is configured to open the direction of injection of the cleaning liquid by the cleaning nozzle 9a. Bearings 8b are attached to the outer surfaces of both frame plates 8c1, respectively. In the first embodiment, the frame plate 8c1 is formed into a square shape, and the support frame 8
Although c has a substantially rectangular parallelepiped shape, the present invention is not limited to this, and the frame plate 8c1 may be formed in a disk shape, and the support frame 8c may have a substantially cylindrical frame structure.

The rotating body 8e is connected to the frame rod 8c2 by a connecting rod 8d, as shown in FIG. As a result, when the support frame 8c supported by the bearing 8b rotates, the rotating body 8e passes through the connecting rod 8d.

Further, as shown in FIGS. 1 and 11, in the first embodiment, as the rotating body 8e, a pair of the first rotating body 8e1 and the second rotating body 8e2 is arranged at the center in the axial direction at the fixed position. It is supported by a support frame 8c via a connecting rod 8d at an equal distance from the position in the front-rear direction. Therefore, even a workpiece W that is long in the axial direction can be supported with good balance. Further, by lengthening the support frame 8c in the axial direction and attaching a plurality of pairs of rotating bodies 8e1 and 8e2, it is possible to arrange a plurality of works W in parallel in the transport direction and realize more washing at once. .

On the other hand, the rotating body 8e is fixed to the inner peripheral surface by the fixing means 7
Are arranged and the work W is made to enter the inner peripheral surface thereof, the orbit of the rotating body 8e must pass below each chain conveyor 6 and collides with it. . Therefore, as shown in FIG. 1 and FIG.
In the first embodiment, the first rotating body 8e1 is arranged between the first chain conveyor 6a and the second chain conveyor 6b, and the second rotating body 8e2 is arranged between the second chain conveyor 6b and the third chain conveyor 6c. Placed between them, each rotating body 8
e1 and 8e2 are prevented from colliding with the chain conveyor 6. For this reason, when each fixing means 7 stops at the fixed position, the upper surface of the fixed seat 7a causes each chain conveyor 6
It is configured to be slightly lower than the height of a, 6b, 6c (FIG. 9 (a)). Therefore, the work W transported to the fixed position can be smoothly transferred to the upper side of the fixed seat 7a and the back surface thereof is supported.

In the first embodiment, the rotating body 8e is formed in a circular shape, but the present invention is not limited to this. As shown in FIG. 13, the rotating body 8e3 is formed in a polygonal shape such as an octagonal shape. May be used.

Next, the cleaning means 9 will be described. As shown in FIGS. 1, 12 and 14, the cleaning means 9 is
A wash water tank 9b that stores wash water is arranged in the wash chamber 3 and below the chain conveyor. A pump 9c such as a plunger pump or a multistage pump is connected to the wash water tank 9b. The cleaning water absorbed thereby is supplied to the four cleaning water supply pipes 9d. A cleaning nozzle 9a is attached to each of the cleaning water supply pipes 9d at right angles outward with respect to each pipe axis. Inside the washing water tank 9b, a purification filter (not shown) and a heat exchange unit for warming the washing water purified by the purification filter are arranged. The pump 9c is disposed adjacent to the cleaning chamber 3 and is driven by the pump motor 9e. This pump motor 9e
Is arranged directly above the pump 9c and above the chain conveyor in order to reduce the arrangement space.

Since it always stops at the fixed position, the four fixing means 7 arranged at equal intervals respectively stop at the upper, lower, left and right positions with respect to the fixed shaft 8a. Therefore, the workpiece W receives the washing water while rotating, and at the stopped position, the washing nozzle 9 is exposed from the front.
Since the cleaning water jet of a is received, the cleaning time at the position where the cleaning power is strongest is extended, and more effective cleaning can be performed.

Further, in the first embodiment, among the respective cleaning water supply pipes 9d, the injection amount of the cleaning nozzles 9a of the cleaning water supply pipes 9d arranged on the left and right is arranged above and below.
It is set to be larger than the injection amount of the cleaning nozzle 9a of d. As a result, the work W stopped or moved near the left and right positions is mainly washed with a large amount of cleaning water, and the work W stopped or moved near the upper position is washed with a small amount of cleaning liquid. This is because the jet pressure in the lateral direction can be made smaller than the jet pressure in the upward direction, so that the amount of jetted water is increased. Further, the wash water is supplied from the wash water tank 9e to the wash water supply pipes 9d arranged on the left and right and above, but the purified water is supplied from a water purification tank (not shown) separately provided to the wash water supply pipe 9d arranged below. Is being supplied. As a result, the work W returned to the fixed position after being cleaned by the cleaning nozzles 9a on the left and right and above is cleanly finished and cleaned.

Is formed to have a length substantially equal to or longer than the length in the transport direction. As a result, the drying air is applied to every corner of the entire work W, and uneven drying does not occur. Further, since the drying air is sprayed not only when the work W is stopped but also when the work W is rotating, the drying air can be applied to the work W at various angles. In the first embodiment, each blower opening 14c is formed in a long slit shape in the rotation center line direction, but the present invention is not limited to this, and a plurality of circular holes may be formed in the rotation center line direction. .

In the work cleaning / drying system 1 of the first embodiment, the cleaning capacity and the drying capacity per sheet can be appropriately adjusted according to the needs of the user and the line capacity of the user. Cleaning is also possible. That is, in the first embodiment, the stopping and fixing of the work W from the carry-in can be completed in about 2.5 seconds, and then the rotating body 8e can be rotated 90 degrees in about 1.5 seconds. In other words, each work W completes the cleaning process in about 16 seconds and is carried out at intervals of 4 seconds, so that about 900 works W can be cleaned per hour.

The cleaning water used in the above-mentioned cleaning step is collected in the cleaning water tank arranged below and purified by the cleaning filter arranged in the cleaning water tank 9b. Then, after being made warm water by the heat exchange unit, it is again absorbed by the pump 9c and supplied to the wash water supply pipe 9d. By circulating the wash water in this way, the cost is reduced.

When the cleaning of the work W is completed, the work W is dried next. Therefore, the third chain conveyor 6c of the work cleaning device 2 conveys the cleaned work W to the work drying device 4. In the work drying device 4, the transporting means 6 is driven by a motor arranged on the back side to receive power, and first, the third chain conveyor 6c puts the work W from the front side to the second chain conveyor 6b. And transfer to a fixed position in the drying chamber 5.

Here, the work drying device 4 is not provided with a stopper that abuts the standby stopper 11a in the work cleaning device 2. This is the position determination stopper 11b of the work cleaning device 2 and the work drying device 4
Since a work detection sensor (not shown) is provided on the position determination stopper 11b, it is possible to detect the state of loading and unloading of the work W, and in accordance with this, the chain conveyors 6a, 6b, 6c of the work drying device 4 and This is because the motor 8f is controlled independently. For example, the chain conveyors 6a, 6a on the work drying device 4 side
By making the conveying speed of b and 6c faster than that of the work cleaning device 2 side, the drying process of the work W is synchronized with the cleaning process, or the rotation speed of the rotor 8e is increased to make the drying distance longer than the cleaning distance. It is also possible to take.

When the work W1 is stopped at the fixed position, the elevating drive section 7d3 of the work drying device 4 is moved to the elevating frame 7d2.
At the same time, the claw contact portion 7d1 is lowered. As a result, the fixing claw 7b1 is lowered by the urging force of the compression coil spring 7c, grips the side edge of the work W1 and presses it against the fixing seat 7a to fix it. Also, each sprocket 6a
1, 6b1, 6b2, 6c1 also descend together with the elevating frame 7d2, and are retracted to a position where they do not come into contact with each other even if the work W1 starts rotating.

On the other hand, the blower 14a has already started to drive, and the drying air compressed by sucking the air in the drying chamber 5 is supplied to the air supply pipe 14b. The supplied drying air travels in the air supply pipe 14b and is blown from each long slit-shaped blower port 14c. And the fixed claw 7b1
When the work W1 fixed by the rotation of the work W1 rotates in the clockwise direction together with the rotating body 8e, the drying air blown from the blower opening 14c2 and the backside blower opening 14d1 blows off moisture on the front and back surfaces of the work W1 to dry it (FIG. 12).
(B)). It should be noted that in the first embodiment, the blower opening 1 for the back surface is used.
A compressor (not shown) may be connected to 4d to inject compressed air. As a result, the work W
It is possible to effectively blow off the water stored in the folded-back portion of the side plate edge portion by the force of the compressed air.

Subsequently, the motor 8f moves the rotor 8e 90
It rotates once to move the fixed claw 7b2 to the fixed position, and stops the rotating body 8e. Then, the lifting drive unit 7d3 raises the lifting frame 7d2 to move the claw contact portion 7d.
1, the claw contact portion 7d1 raises the fixed claw 7b2 while contacting the lower surface thereof. This allows the work W2
A space to accept At this time, the sprockets 6a1 and 6a that have been raised together with the lifting frame 7d2.
b1, 6b2, 6c1 chain conveyor works W
2 is conveyed to a fixed position and brought into contact with the position determination stopper 11b for positioning. Thereafter, when the lifting drive unit 7d3 lowers the lifting frame 7d2 to lower the pawl contact portion 7d1, the fixed pawl 7b2 causes the compression coil spring 7 to move.
The work W2 is lowered by the urging force of c, and at this time, the hook portion 7f is hooked on the side plate edge of the work W2 and descends, so that the work W2 is pressed and fixed to the fixed seat 7a.

While the work W2 is fixed in this manner, the work W1 is erected vertically and blown into the air outlet 14c.
2 and the drying air of the back side ventilation port 14d1 are received from the front side, the moisture is blown away, and the first main drying is performed.

As described above, each work W is fixed at 1/4 intervals, and while being rotated by the rotating body 8e, it is rotated once to complete the drying of one sheet. While the rotating body 8e makes one round, the work W is stopped at each of the upper, lower, left, and right positions to receive the drying air from the front, and the main drying is performed four times. Then, when the drying of the work W1 is completed, the work drying device 4
The first chain conveyor 6a conveys the dried work W1 downstream and stores it at a predetermined position.

In the first embodiment, the blower 14a
The drying air supplied by K.K. is not particularly heated by a heater or the like. This is because if the work W is dried with too hot hot air, the work W itself becomes extremely hot, cannot be used immediately after drying, and requires a cooling time. In the first embodiment, the blower 14a is the drying chamber 5
Since the cycle of sucking and compressing the drying air from the unit and blowing the air into the drying chamber 5 again is repeated, the temperature of the air rises due to this circulation, the drying is easy, and the cooling step is not required after the drying. To generate the appropriate temperature air. Therefore, according to the first embodiment, the work W after drying can be immediately used without taking another time to cool it.

Further, in the drying process of the work drying device 4, the wash water is blown off or droops from the work W, but the wash water is collected in the wash water tank 9b arranged below. Since this cleaning water tank 9b is a tank shared with the work cleaning device 2, the cleaning water tank 9b is purified by a purification filter (not shown), heated by a heat exchange unit, and supplied again to the cleaning water supply pipe 9d.

Therefore, according to the first embodiment, the work W is fixed and rotated on the rotating body 8e which rotates about the center line parallel to the carrying direction, and cleaning and drying are performed during the rotation. Therefore, although the lengths of the work cleaning device 2 and the work drying device 4 in the longitudinal direction are shortened, the cleaning time and the drying time can be sufficiently secured, and the number of cleanings and the number of dryings per unit time can be increased. it can. For example, compared with a conventional work cleaning / drying system that performs cleaning / drying while conveying in the longitudinal direction, the total length can be reduced to about 40% with the same cleaning and drying capacity.

Further, according to the first embodiment, when it is desired to wash and dry a larger number of works W, the support frame 8c is lengthened to increase the number of rotating bodies 8e, and the fixing means 7 is provided. Just add more. Therefore, it is possible to extremely easily increase the number of sheets to be washed and the number of sheets to be dried per unit time without taking a large additional space.

Further, according to the first embodiment, since the work W is continuously washed and dried not only when the work W is stopped but also when the work W is rotating, a high washing effect and a high efficiency can be achieved. It can be effective.

Further, since the work W is washed and dried while rotating on the circumference and stopping, the wash water and the drying air are received from various angles to prevent dirt such as burnt dust from coming off. It can wash dirt and dust more effectively and can be dried quickly and evenly. Furthermore, since the work W is washed and then dried with the appropriate temperature air, the work is quick and can be used immediately after the drying, and the work W can be repeatedly used in the whole work such as the bread making process. .

Next, a second embodiment of the work cleaning / drying system 1 according to the present invention will be described with reference to FIG.

Among the configurations of the second embodiment, configurations the same as or corresponding to those of the first embodiment described above are designated by the same reference numerals, and their description will not be repeated.

The feature of the second embodiment is that the rotating means 8 has a fixed shaft 8a and a bearing 8b among the components of the first embodiment.
The point is that the support frame 8c is not provided. That is,
As shown in FIG. 19, the rotating means 8 includes a ring-shaped rotating body 8e4 that rotates around a center line parallel to the transport direction of the work W to the fixed position, and a rotating body that rotatably supports the rotating body 8e4. A support portion 8g, an endless endless gear portion 8h provided so as to go around the outer peripheral surface of the rotating body 8e4 once,
It is composed of a drive transmission gear portion 8i that meshes with the endless gear portion 8h to rotate the rotating body 8e4.

As shown in FIG. 19B, the rotating body 8e4 in the second embodiment has a wide width.
This width is formed at an interval substantially the same as the interval between the two rotating bodies 8e1 and 8e2 arranged side by side in the first embodiment described above. Therefore, a pair of fixing means 7, 7 are juxtaposed in the width direction on the inner peripheral surface of the rotating body 8e4.

Further, the rotating body supporting portion 8g for supporting the rotating body 8e4 supports the lower side of the outer peripheral surface of the rotating body 8e4 at two places on the left and right. An endless gear portion 8gh is formed on the outer peripheral surface of the rotating body supporting portion 8g.
It meshes with the endless gear part 8h. The two rotor support portions 8g, 8g and the drive transmission gear portion 8i are arranged at equal intervals on the outer peripheral surface of the rotor 8e to rotatably support the rotor 8e4. As a result, the drive transmission gear portion 8i meshes with the endless gear portion 8h of the rotating body 8e4 to rotate the rotating body 8e4,
It is not necessary to provide the fixed shaft 8a, the bearing 8b, the support frame 8c, etc. inside the rotating body 8e4, and the rotating body 8e4 can be rotated around the center line.

Therefore, according to the second embodiment, in addition to the effects of the above-described first embodiment, the direction of the cleaning liquid sprayed from the cleaning nozzle 9a and the drying air blown from the blower port 14c can be improved. Nothing obstructs the direction of air flow,
Effective cleaning and drying are possible.

Further, the work cleaning device 2 may be provided with means for self-cleaning the inside of the cleaning chamber 3. For example, the standby stopper 1
A contact sensor is provided in 1a, and when the work W is not conveyed and the work W contacting the standby stopper 11a is not detected for a certain period of time or longer, the cleaning water is jetted from the cleaning nozzle 9a to wash the inside of the cleaning chamber 3. You may make it wash | clean the inner wall and fixing means 7. Conventionally, since the inside of the cleaning chamber 3 has to be cleaned every few months, if a self-cleaning means is provided, it can be kept clean at all times and the time and effort of regular cleaning can be saved.

On the other hand, in each embodiment, the work cleaning device 2
Further, the work drying devices 4 are integrally arranged side by side so that they can be continuously operated. However, the invention is not limited to this, and the device for cleaning the work W and the device for drying the work W are independently configured. You may.
