Description

  The present invention relates to a liquid coating apparatus for applying a liquid to an object to be coated conveyed by a conveying apparatus, and more specifically, a movable body and a plurality of supported movable bodies independently movable in the conveyance orthogonal direction with respect to the movable body. The present invention relates to a liquid application apparatus capable of individually applying movement control of an application nozzle and applying a uniform amount of liquid to each application location on an object to be applied.

  In Patent Document 1, the syringe holding the liquid material is moved in the XYZ axial directions orthogonal to each other by the moving means, and the position of the coating nozzle tip in the XYZ axial direction is determined by the position detecting means. The liquid material is detected by moving the syringe by a necessary distance in the XYZ axis direction by the moving means based on the position in the XYZ axis direction of the coating nozzle tip detected by the position detecting means. A liquid application device that applies to a predetermined position is disclosed.

  However, in the above-described liquid application apparatus, in order to apply a liquid material to a plurality of application locations on the application target, the syringe is moved and controlled in the X, Y, and Z axis directions relative to each application location. After application, it has to be applied in order, and the application work takes time and has a problem of poor work efficiency.

The above-mentioned problem can be solved by simultaneously applying a liquid material to a plurality of application locations in an object to be applied by providing a plurality of syringes that move in the X, Y, and Z axis directions to form a liquid application apparatus. However, in this case, there is a problem that the size of the device itself is increased and the movement control is complicated so that the syringes do not interfere with each other, and the cost of the device itself is increased.

  Patent Documents 2 and 3 disclose oils for applying edible oil on a top plate on which these doughs are placed when baking bread, confectionery, etc. (hereinafter collectively referred to as bread). A coating apparatus is disclosed. When oil is applied to the top plate used for baking such breads and confectionery, the oil is uniformly applied to the dough placement area over the entire amount, Therefore, it is necessary to minimize the application of edible oil to the outside of the dough placement area because it is necessary to reduce the amount of consumption and to simplify the cleaning after use.

Among them, in the oil application device of Patent Document 2, the top plate conveyed by the conveying means is directly below the nozzles below the oil injection means having a plurality of nozzles to which pressurized air and oil are supplied. The control means controls the opening and closing times of the nozzles to adjust the amount of oil applied to the dough placement area on the top plate so as to be optimized.

However, in the oil coating apparatus shown in Patent Document 2, since a plurality of nozzles are fixedly attached to the main body frame, the nozzle for the main body frame is different when the oil application pattern in the material to be coated is different. The mounting position must be changed each time, and there is a problem that the change work takes time and the coating workability deteriorates.

Especially in the top plate for confectionery, since the shape of the dough placement area is complicated or concave, the oil application device in which each nozzle is fixedly attached to the main body frame Further, it is difficult to uniformly apply the oil to the dough placement area, and the oil is also applied to the outside of the dough placement area.

In the oil coating apparatus of Patent Document 3, an ink jet printer type nozzle is disposed at a position opposite to the surface of the top plate that is placed on a conveyor and conveyed, and the ink application apparatus is based on a pre-stored spray pattern. The nozzle is driven and controlled, and granular edible oil is sprayed and applied by an ink jet method.

However, in the oil application device shown in Patent Document 3, it is necessary to apply edible oil in a desired pattern on the top plate and apply it in a desired pattern. It has to be used and has the problem of increasing edible oil costs. In addition, when conventional edible oil is used in the above-described oil coating apparatus, the viscosity is high, so that it is difficult to fly in granular form, it becomes difficult to apply edible oil in a desired pattern, and nozzle clogging occurs. There was a fear, and it was difficult to efficiently apply the cooking oil to the top plate.

Further, in the ink jet system, a liquid dedicated to ink jet having a low viscosity must be used, which increases the cost of the liquid. When using a conventional liquid with a high viscosity, it is difficult to disperse in a granular form, which makes it difficult to apply the liquid in a desired application pattern and may cause nozzle clogging. It is in the point that it becomes difficult to perform work efficiently.

Next, the application | coating effect | action to the top plate 3 by the edible oil coating apparatus 1 for bread baking comprised as mentioned above is demonstrated.
First, the first application action when applying cooking oil to the top plate 3 (see FIG. 7) on which the same number (six) of concave molds 3a as the number of injection nozzles 51 is formed in the conveyance orthogonal direction will be described. When the type of the top plate 3 is set in the control means 61 prior to the edible oil application operation, the control means 61 reads the pattern data relating to the top plate 3 set from the pattern storage area and stores it in the work storage area. Let

Then, the control means 61 drives and controls the electric motor 19 based on the pattern data stored in the work storage area, and moves the lifting body 27 to a predetermined height position set in advance according to the height of the top plate 3. The spray nozzle 51 is moved down to move to a predetermined height position with respect to the top 3.

Moreover, the control means 61 carries out conveyance drive of the conveying apparatus 5 by which the top plate 3 was set in the carrying-in side, and when the top plate 3 is located in an edible oil application position, the top plate detection output from the top plate detector 16 is carried out. Based on the signal, the conveyance drive of the conveyance device 5 is stopped.

In the above state, the control means 61 drives and controls the electric motor 37 based on the pattern data, moves the movable body 33 in the conveyance orthogonal direction, and matches the central portion with the conveyance orthogonal direction central portion of the elevating body 27. At the same time, each electric motor 47 is driven and controlled to move the corresponding injection nozzle 51 so as to be positioned above the center of each concave mold 3a in the top plate 3. (See Figure 8)

In the above state, the control means 61 supplies edible oil and compressed air to each injection nozzle 51 based on the pattern data for a preset time and responds to the corresponding concave mold 3a according to the injection time. A predetermined amount of edible oil is sprayed, and the edible oil is applied to the inner surface of the concave mold 3a.

The control means 61 drives the transfer device 5 again at the timing when the injection time from each injection nozzle 51 with respect to the inside of each concave mold 3a on the top plate 3 has passed, or at the timing slightly delayed, to drive the inside of each concave mold 3a. The top plate 3 to which the cooking oil is applied is transported to the carry-out side, and the top plate 3 to which the cooking oil is applied next after being set on the carry-in side is carried into the cooking oil application position.

In addition, when the next top plate 3 is carried into the edible oil application position, if there is a possibility that the top plate 3 and each of the injection nozzles 51 interfere with each other, the control means 61 performs the timing for transporting the transport device 5. Thus, the electric motor 19 is reversely driven to raise the elevating body 27 to the standby position, and control is performed so as to avoid the interference of the injection nozzle 51 with the top plate 3 carried into the cooking oil application position.

Furthermore, although the said description demonstrated the example which apply | coats cooking oil with respect to the top plate 3 in which the six concave molds 3a were arranged with respect to the conveyance orthogonal direction, the said six concave molds 3a are with respect to a conveyance direction. When edible oil is applied to the top plates 3 arranged in a plurality of rows, the conveying device 5 is moved forward by one row after the edible oil is first applied in the concave mold 3a arranged in the first row by the above-described action. Alternatively, the concave mold 3a on the next line is moved backward to be positioned below the respective injection nozzles 51 to apply cooking oil, or each concave mold 3a on the top plate 3 is long in the conveying direction and is edible by one injection. When oil cannot be applied, edible oil is sprayed from the spray nozzle 51 while the transport device 5 is moved forward or backward, and the interior of each concave mold 3a is applied over the entire transport direction.

Next, edible oil is applied to the top plate 3 (see FIG. 9) in which the number of the concave molds 3a, which is smaller than the number of the injection nozzles 51 in the orthogonal direction of conveyance (three in this example), is arranged. The second application action at the time of application will be described. When the type of the top plate 3 is set in the control unit 61, the control unit 61 reads pattern data related to the top plate 3 set from the pattern storage area. To be stored in the working storage area.

Then, the control means 61 drives and controls the electric motor 19 based on the pattern data stored in the work storage area in the same manner as in the first application action, so that the lifting body 27 is preset according to the height of the top 3. Moved down to the predetermined height position and moved each injection nozzle 51 to a predetermined height position with respect to the top plate 3 and driven and controlled the electric motor 37 to move the movable body 33 in the conveyance orthogonal direction. The central portion is made to coincide with the central portion in the conveyance orthogonal direction of the elevating body 27.

Moreover, the control means 61 carries out conveyance drive of the conveying apparatus 5 by which the top plate 3 was set in the carrying-in side, and when the top plate 3 is located in an edible oil application position, the top plate detection output from the top plate detector 16 is carried out. Based on the signal, the conveyance drive of the conveyance device 5 is stopped.

The control means 61 first drives and controls each electric motor 47 of the moving body 43 positioned on both end sides in the conveyance orthogonal direction after the timing synchronized with the above operation or after the above operation, and moves the corresponding injection nozzle 51 to the movable body. 33, move to the non-coating position on the end side in the direction perpendicular to the conveyance direction to stand by, and drive and control the electric motors 47 of the remaining four moving bodies 43 above the center of each concave mold 3a on the top plate 3. Move to position. (See Figure 10)

In the above state, the control means 61 controls the edible oil 51 and the edible oil 51 to be opposed to the four concave molds 3a while restricting the supply of the edible oil and the compressed air to the respective jet nozzles 51 moved to both ends in the conveyance orthogonal direction. Compressed air is supplied for a preset time, and a predetermined amount of edible oil corresponding to the injection time is injected into each concave mold 3a, and the edible oil is applied to the inner surface of the concave mold 3a.

In addition, when the concave mold 3a of the top plate 3 has a width with respect to the conveyance orthogonal direction, the edible oil is entirely injected with respect to the inner surface of the concave mold 3a only by injecting the cooking oil from the injection nozzle 51 located above the concave mold 3a. It is difficult to apply uniformly over the whole area. In such a case, each electric motor 47 corresponding to each concave mold 3a is driven and controlled based on the pattern data so that the injection nozzle 51 is positioned on one side of the concave mold 3a in the conveyance orthogonal direction. When injecting edible oil from the nozzle 51, the electric motor 37 is driven and controlled to move the movable body 33 to the other side in the conveyance orthogonal direction, so that the edible oil is uniformly distributed over the inner surface of the concave mold 3a. What is necessary is just to control so that it may apply.

Further, instead of moving the movable body 33 in the conveyance orthogonal direction, each electric motor 47 corresponding to each concave mold 3a is driven to move each injection nozzle 51 from one side to the other side of the concave mold 3a in the conveyance orthogonal direction. What is necessary is just to control so that edible oil may be sprayed and the edible oil may be uniformly applied to the inner surface of the concave mold 3a.

Moreover, when the concave mold 3a of the top plate 3 has a width with respect to the conveying direction, the edible oil is entirely injected to the inner surface of the concave mold 3a only by injecting the edible oil from the injection nozzle 51 located above the concave mold 3a. It is difficult to apply uniformly. In such a case, based on the pattern data, each electric motor 47 is driven and controlled so that the injection nozzle 51 is positioned on one side in the transport direction (upper side or lower side in the transport direction) of the concave mold 3a. When injecting edible oil from the injection nozzle 51, the electric motor 15 is driven and controlled to move the conveying device 5 backward or forward so that the injection nozzle 51 moves to the other side in the conveying direction of the concave mold 3 a to move the inner surface of the concave mold 3 a. On the other hand, it controls so that edible oil may be uniformly apply | coated throughout.

Furthermore, although the said description demonstrated the example which apply | coats cooking oil with respect to the top plate 3 with which the three concave molds 3a were arranged with respect to the conveyance orthogonal direction, the said three concave molds 3a are with respect to a conveyance direction. In the case of applying edible oil to the top plates 3 arranged in a plurality of rows, first the edible oil is first applied to the concave molds 3a arranged in the first row by the above-described operation, and then the conveying device 5 is arranged for one row. Then, the concave mold 3a in the next row is moved forward or backward to be positioned below the respective injection nozzles 51, and edible oil is applied.

Next, the top plate 3 in which the number of the injection nozzles 51 is less than the number of the injection nozzles 51 (two in this example) and the ring-shaped concave molds 3a having the projecting molds 3b in the center are arranged in the conveyance orthogonal direction. And a third application action when applying cooking oil to the top plate 3 on which the concave molds 3a having an application surface wider than the injection area by the injection nozzle 51 are arranged (FIG. 11 has a protrusion 3b at the center. The ring-shaped concave top 3a will be described as an example.) When the type of the top 3 is set in the control means 61, the control means 61 is set from the pattern storage area. The pattern data relating to the top plate 3 is read out and stored in the work storage area.

Then, the control means 61 drives and controls the electric motor 19 based on the pattern data stored in the work storage area in the same manner as in the first or second application action, so that the elevating body 27 is adjusted according to the height of the top plate 3. Then, the spray nozzle 51 is moved down to a predetermined height position to move each injection nozzle 51 to a predetermined height position with respect to the top plate 3, and the electric motor 37 is driven to control the movable body 33 in the conveyance orthogonal direction. It moves and the center part is made to correspond with the conveyance orthogonal direction center part in the raising / lowering body 27. FIG.

Moreover, the control means 61 carries out conveyance drive of the conveying apparatus 5 by which the top plate 3 was set in the carrying-in side, and when the top plate 3 is located in an edible oil application position, the top plate detection output from the top plate detector 16 is carried out. Based on the signal, the conveyance drive of the conveyance device 5 is stopped. At this time, each injection nozzle 51 is positioned, for example, on the upper side in the transport direction in each concave mold 3a. (See Figure 12)
