Description

  The present invention is, for example, when a variety of buried boxes such as handholes and manholes buried for the construction of electric wire routes, the concrete material into the form, by solidification, when the mold release agent on the inner surface of the form The present invention relates to a mold release agent spraying apparatus for concrete product formwork, which is capable of performing uniform spray application and capable of performing a coating process corresponding to the form even when the form is different in height, size and the like.

  Conventionally, this type of buried box is, for example, an inverted box-shaped inner form that is opened and lowered at the lower side, and is configured to have a peripheral wall thickness that can fall outward around the inner form and is divided into two. Molding is performed by filling a concrete material between the inner mold frame and the outer mold frame with a mold device including an outer mold frame that is detachably connected.

  In addition, by applying a mold release agent to the inner surface of the mold, that is, the outer surface of the inner mold and the inner surface of the outer mold, it is easy to remove and remove the concrete product after curing and solidifying the filled concrete material. I can do it.

  At this time, the spray application of the release agent onto the mold surface is performed, for example, by a worker having a nozzle connected to the release agent tank and spraying the release agent at a predetermined pressure, and facing the mold surface. This is a nozzle device that spray-coats while moving on a frame surface and is used in, for example, a mold release agent spraying method disclosed in Patent Document 1.

  Alternatively, a release agent spraying device disclosed in, for example, Patent Documents 2 and 3, in which a nozzle holder having a large number of nozzles arranged in parallel is moved along a mold surface to perform spray application within a certain range. It is.

  However, in the nozzle device disclosed in Patent Document 1, since a spray is applied by moving a nozzle toward a formwork surface by an operator, the coating thickness of the sprayed surface of the formwork is not uniform. In many cases, unevenness occurs, and thus, the work of removing the concrete product from the mold may not be performed smoothly.

  Further, in the release agent spraying devices disclosed in Patent Literatures 2 and 3, since a plurality of nozzles are disposed, spraying processing can be performed over a wide range of a sprayed surface, and the nozzles are formed as long nozzles. For example, it is appropriate to apply the injection port close to the injection surface of a mold used in a die casting machine. However, in order to carry out on the sprayed surface of a mold for molding concrete products such as a buried box, since each mold has a different height and size, it is necessary to apply It is necessary to control the range, the spray height, etc., which is troublesome.

  In addition, in these Patent Documents 1 to 3, when the release agent is sprayed on the surface to be sprayed, the release agent in the form of a spray scatters around and not only contaminates the periphery but also deteriorates due to fouling and the like. This has caused a great burden on workers working in the work environment.

  Accordingly, the present invention has been created in view of the above-described existing circumstances, and has as its object to mainly carry out continuous transportation so that a concrete product such as a buried box can be continuously formed while removing the product from the mold release. The spraying agent can be sprayed smoothly without scattering the mold release agent around the mold, and can be sprayed evenly on the sprayed surface of the mold on average, and adjustment corresponding to different heights, sizes, etc. for each mold It is an object of the present invention to provide a release agent spraying device for a concrete product formwork which can be set and can be efficiently implemented.

Is controlled by the nozzle lifting mechanism 41 and the nozzle moving mechanism 55 to move the nozzle spray mechanism 61 up and down inside the surrounding frame 21 closed by the opening / closing gate 27. In accordance with the instruction, the mold release agent is sprayed onto the mold S by a predetermined number of selected and controlled nozzles 62 at a designated height position above the mold S in the disassembled and deployed state.
Upon detection of the positioning holes 11 provided in the transfer table 10 to be transferred, the position of the transfer table 10 is stopped at the center position of the spray application area 20 and other processing areas. Further, since the stopper 12 is fitted into the positioning hole 11, the transport table 10 does not move or move up and down, and the concrete product C is easily taken out from the form S integrated with the transport table 10, for example.
The surrounding frame body 21 loads and unloads the mold S transported on the transport path 2 by opening and closing the opening / closing gate 27, and releases the mold release agent to the mold S that is stopped and held inside when closed by the nozzle device 40. When spraying, do not scatter the release agent to the outside.
In the nozzle device 40 including the nozzle raising / lowering mechanism 41, the nozzle moving mechanism 55, and the nozzle spraying mechanism 61, the lifting / lowering height position corresponding to the spraying height of the nozzle 62 by the control mechanism (46, 65), the development shape of the mold S, and the like. The number of sprays of the nozzle 62 and the selection / elevation / movement interval of the spray operation part corresponding to the nozzle 62 are controlled and the spray operation is performed corresponding to each of the different molds S.
When the nozzle lifting / lowering sprockets 43A and 43B, which are driven and rotated by the driving of the lifting / lowering motor 42, are rotated in the forward and reverse directions, the nozzle lifting / lowering sprockets 43A and 43B and the lifting / lowering base 37 of the nozzle lifting / lowering mechanism 41 are rotated. The lifting and lowering base 37 is not tilted, and the nozzle base 38 of the nozzle spray mechanism 61 is extended by winding and retracting the nozzle raising / lowering chains 44A and 44B, respectively. All of them are raised and lowered in the same direction without tilting.

Then, the spray operation of the nozzle 62, which is started with the movement of the nozzle spray mechanism 61, is prepared and put on standby.
The nozzle moving mechanism 55 is driven by the moving motor 56, and the moving chain 57 circling along the elevating base 37 is driven and circulated, and the nozzles 62 in the nozzle spray mechanism 61 are arranged while being guided by the traveling guide means 39. The nozzle base 38 is moved and moved on the formwork S.
The nozzle spray mechanism 61 is configured to perform the spraying operation of the nozzles 62 in each of the time zone and the movement area where the nozzle 62 is moved on the form S by the ON-OFF instruction to the nozzle display button 66 in the spray operation control panel 65, the spray operation. By controlling the selection of the part, the dismantled and unfolded form S is made to have a spray form while moving corresponding to the plane form.
The contact avoiding means 71 provided in the nozzle spray mechanism 61 is controlled to stop at a spray height position with respect to the mold S stopped on the transport path 2 by lowering the nozzle base 38 by the nozzle elevating mechanism 41. When the nozzle 62 comes in contact with the form S when the nozzle 62 is lowered more than necessary beyond the spray height position, the lowering operation is stopped.

  Since the present invention is configured as described above, when molding a predetermined concrete product C, a predetermined process is performed while the form S is being conveyed on the conveyance path 2, and is dismantled and expanded. When stopped and held in the surrounding frame body 21 of the spray application area 20, the nozzle S is moved by the nozzle 62 which travels at the spray height position adjusted up and down in accordance with the height of the mold S by the nozzle device 40. The release agent can be uniformly spray applied to the inner surface.

  That is, when the present invention spray-applies the release agent to the inner surface of the mold S in the spray application area 20 defined in the conveying path 2 for conveying the mold S for molding the concrete product C, A nozzle device 40 that sprays and applies a release agent from above while moving on a mold S that is temporarily stopped and held in the application area 20, and corresponds to the height, size, and development of the mold S. This is because the nozzle device 40 is provided with a control mechanism (46, 65) for controlling the spray height position of the nozzle 62, the number of sprays, the selection of the spray operation part, the elevation, and the movement interval. Thereby, uniform spray application of the release agent from a predetermined spray height position corresponding to each of the dismantled and developed different molds S can be realized by automatic control.

  Further, the spray application by the nozzle 62 to the mold S is performed inside the surrounding frame 21 that covers the mold S stopped and held on the spray application area 20 in the transport path 2, so that the surrounding frame 21 can be opened and closed. The mold release agent is spray-applied by the nozzle device 40 inside the enclosed frame 21 almost closed to the mold S carried in through the opening / closing gate 27, so that the mold release agent is not scattered around. I'm done.

  The transport table 10 transported on the transport path 2 detects the positioning holes 11 set at equal intervals from the center position before and after along the transport direction during transport, and transports to the central position for each processing area. The platform 10 can be positioned and stopped, which is useful for reliably performing, for example, demolding, dismantling, cleaning, spray coating, loading of the reinforcing bar S3, and other operations of the formwork S. Further, since the stopper 12 is fitted into the positioning hole 11, for example, when the concrete product C is taken out from the form S, the form S integrated with the carrier 10 is prevented from moving back and forth, up and down, and the like. Therefore, the take-out operation can be performed smoothly.

  The nozzle device 40 raises and lowers the nozzle spray mechanism 61 provided with the nozzle base 38 in which the nozzles 62 are arranged by the nozzle lifting mechanism 41 at a spray height position corresponding to the height of the mold S. Is moved by the nozzle moving mechanism 55 along the form S while maintaining the height position, so that the form height and the height position corresponding to the spray height of the nozzle 62 by the control mechanism (46, 65), the developed shape, and the like are different. The spraying operation can be performed by controlling the number of sprays of the nozzle 62, the selection of the spraying operation site, the ascending / descending / moving intervals, and the like corresponding to each of S.

  The nozzle elevating mechanism 41 is a nozzle elevating chain 44A wound or unwound on a pair of nozzle elevating sprockets 43A, 43B supported on the base frame 36 so as to be driven and rotated by an elevating motor 42 supported and fixed to the base frame 36. , 44B are connected to the lifting base 37. Thus, when the nozzle rotating sprockets 43A, 43B that are driven and rotated are rotated in the same direction in the forward and reverse directions, the nozzle lifting chains 44A, 44B are respectively pulled up by being wound up, or extended by being unwound to be extended up and down. The entirety of the nozzle 37 is moved up and down in a stable state without tilting, so that the nozzle spraying mechanism 61 can be stably moved and moved by the nozzle moving mechanism 55 at the elevation stop position.

  The height setting control means 46 detects the movement following the elevation of the elevation base 37 so as to be detected by the elevation positioning sensors 48 arranged at each height position corresponding to the control instruction of the spray height position of each of the different molds S. When the body 51 reaches the position of the predetermined vertical positioning sensor 48 instructed corresponding to the height of the form S, the lifting operation is stopped, so that the lifting base 37 can be moved at the predetermined spray height position. Is stopped, and the spraying operation started with the movement of the nozzle base 38 by the nozzle moving mechanism 55 is prepared and put on standby.

  The nozzle moving mechanism 55 is driven by a moving motor 56 to circulate a moving chain 57 which is supported by the elevating base 37 and is connected to the nozzle base 38, and moves and runs the nozzle base 38 while being guided by the running guide means 39. By doing so, the nozzle base 38 on which the nozzles 62 are arranged can be moved and run on the mold S along the elevating base 37 while maintaining the spray height position.

  The nozzle spray mechanism 61 includes a plurality of nozzles 62 that are arranged on a nozzle base 38 that is moved up and down and moved, and each of the spray operations is controlled so as to spray a release agent. The adjustment is based on a control instruction on the spray operation control panel 65 which displays the number of nozzle display buttons 66 corresponding to the number of nozzles 62 sprayed in each of the time zone and the movement area in which the nozzle 62 moves. Therefore, by instructing ON / OFF of the nozzle display button 66, it is possible to control the number of sprays of the nozzles 62 to be spray-operated when being moved on the mold S, and the selection of the spray-operated portion, and the disassembly and development are performed. In the plane shape of the formwork S, for example, in the initial stage of movement, the final stage of movement, and the middle stage of movement, it is possible to make the spray form while moving corresponding to the width of the different development width.

  Further, the contact avoiding means 71 provided in the nozzle spray mechanism 61 is configured to detect the suspended detection wire 72 positioned below the lowermost position of the nozzle 62 by the extension sensor 75, for example, a formwork. If the setting instruction is incorrect when setting the height corresponding to S (human error) or the like, the nozzle base 38 is not controlled to stop at the spray height position with respect to the mold S by the nozzle elevating mechanism 41, and the spraying is performed. The lowering operation is stopped when the nozzle 62 is unnecessarily lowered beyond the height position to prevent the nozzle 62 from coming into contact with the mold S, so that the nozzle 62 and the like are not damaged.

  Note that the reference numerals added in each of the means for solving the above-described problems and the effects of the invention are given to facilitate reference to the parts indicating the components shown in the drawings. The present invention is not limited to these descriptions and the structures and shapes indicated by reference numerals and the like in the drawings.

(Overview)
Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the drawing indicates that each processing is performed while moving a form S so as to form a concrete product C such as a buried box. Is a production line for carrying out the process. The production line 1 includes a transport path 2 for performing each process while transporting a concrete product C formed and formed in a mold S together with a mold S by a carrier 10. As shown in FIG. 1 and FIG. 2, the conveying path 2 has a carry-in area 3 in which a form S in which a concrete product C is molded is carried by a carrier 10, and the form S is dismantled to form a concrete product C. Area 4, a cleaning area 5 for cleaning the dismantled form S after removal, a spray application area 20 for spray-applying a release agent to the form S after cleaning, a spray application. Reinforcement loading area 6 for loading and preparing rebar material S3 in formwork S assembled later, filling area 7 for filling and injecting predetermined concrete material into transported formwork S after loading rebar, concrete Each of the unloading areas 8 for unloading the filled form S is continuously arranged.

  In the illustrated example, the transport path 2 is configured such that a transport roller that is rotationally driven is sequentially and continuously arranged, and for each processing range partitioned so as to perform each processing operation, a predetermined drive roller that drives the transport roller within the processing range. A transport motor 14 is provided for each processing area. When the predetermined processing is completed in each of the processing areas, the conveyance table 10 on which the formwork S is mounted in the next processing area is conveyed, and when the processing area becomes empty, the formwork before the predetermined processing is performed from the preprocessing area side. S are transported sequentially so that there is no so-called empty space between the processing areas during transport of the mold S. In the present specification, unless otherwise specified, the transport of the form S is meant to be transported together with the transport platform 10.

  In the carry-in area 3, the molded concrete product C after curing and solidification for a predetermined period is carried in together with the formwork S in a state in which the molded concrete product C is stored, and is conveyed to the product take-out area 4 by a driven conveying roller.

  The product take-out area 4 is to disassemble and unfold the form S, to suspend the concrete product C solidified and molded inside the form S by, for example, an overhead crane, to pull it out of the form S by pulling it up, and to remove it from a predetermined storage location. Move to The mold S is connected to, for example, an inverted box-shaped inner mold S1 which is opened and lowered at the lower side, and which can fall down and can be separated from each other around the inner mold S1 by setting a peripheral wall thickness. The outer mold S2 is divided into a total of four molded pieces, for example, front, rear, left and right. The concrete product C is opened outwardly in a morning glory at a predetermined inclination angle by releasing the lock fitting S4 between the molded pieces in the outer mold S2 to be divided. The form S is dismantled by expanding it in a developed state, and thereafter, the concrete product C formed and exposed in the shape of an inverted box is drawn out and taken out.

  The cleaning area 5 removes the remaining concrete material debris and the like adhering to the form S, cleans the inner surface of the form S, and transports the form S to the spray application area 20.

  When a predetermined release agent is spray-applied by the spray application area 20, the release agent is conveyed to the reinforcing bar charging area 6, where the reinforcing product is pre-assembled and formed by a reinforcing bar having a predetermined diameter. The rebar material S3 serving as the core of the mold S is loaded, and the outer formwork S2 of the formwork S in the upper opening state is set up so as to close the outer formwork S2, and the formwork S is assembled by locking with the lock fitting S4. Lock.

  The filling area 7 is for filling and supplying a concrete material mixed and formed at a predetermined ratio in the form S on the transfer table 10 that has been transferred from the reinforcing bar charging area 6 through the traverser 9. By swinging and vibrating the mold S, the concrete material can be distributed to every corner in the mold S.

  The carry-out area 8 is configured to carry out the form S filled with the concrete material from the manufacturing line 1 and to carry out steam curing for a predetermined period of time, for example, 12 to 24 hours in a curing building or a factory.

(Transport table)
The mold S is carried along with the carrier 10 transported and moved on the carrier roller in a state where the mold S is mounted and integrated with the mold S. The mold S itself is transferred to the carrier 10. They may be integrated by welding or may be integrally connected by a predetermined fixing member or the like. The transfer table 10 is formed, for example, by combining frame materials that are paired in front and rear, left and right in a substantially cross-girder shape when viewed from a plane, and are the same in the front and rear from the center position along the front and rear direction of the left and right frame materials. The positioning holes 11 set at equal intervals are formed in front and rear directions (see FIG. 4).

  In this way, when the transfer table 10 is transferred on the transfer path 2, for example, the positioning hole 11 on the front side is detected by the transfer table positioning sensor 13 provided in each processing area, and the detected position is detected. By measuring and determining a certain interval from the positioning hole 11, the center position of the transfer table 10 can be matched with the center position in each processing area. At the time of matching, the drive of the transport motor 14 is stopped, and the transport table 10 is temporarily stopped in each processing area.

  The positioning hole 11 is adapted to be fitted with a stopper 12 which is fed out by, for example, the operation of a cylinder in the product take-out area 4, and thus the stopper 12 is fitted into the positioning hole 11 so that the movement is up and down. The form S integral with the form 10 can be held in a fixed state via the transfer table 10 that does not move and does not move, so that the concrete product C can be smoothly taken out (see FIG. 3). The stopper 12 can be provided in other processing areas if necessary.

(Transport path)
As shown in FIGS. 6 and 7, the transport path 2 itself is formed of a steel plate having a predetermined thickness, and is formed, for example, by dividing the central portion along the transport direction and the right and left portions on both sides into three parts. The transport rollers exposed between the central portion and the left and right portions are driven and rotated by the transport motor 14, so that the transport table 10 placed on these transport rollers is moved and transported forward along the transport path 2. In particular, in the transport path 2 portion in the spray application area 20, a shallow V-shaped oil drain path 15 is formed along the center line along the transport direction in each of the central portion and the left and right portions. The oil path 15 is connected to an oil sump 16 arranged outside the transport path 2. As a result, the liquid release agent sprayed in the surrounding frame body 21 described later and dropped from the wall surface, the device surface or the like is stored in the oil sump 16 via the oil drain passage 15.

(Spray application area)
In the spray application area 20, a predetermined amount is applied to the inner surface of the mold S in a developed state after cleaning, which is sequentially conveyed on the conveyance path 2, that is, the outer surface of the inner mold S1 and the inner surface of the outer mold S2.

The base frame 36 is mounted on the ceiling side wall 25 of the surrounding frame 21 and is mounted on the ceiling frame 25. The nozzle moving mechanism 55 is mounted on the elevating base 37 supported by the nozzle elevating mechanism 41 provided on the base frame 36. (See FIG. 6). The nozzle spray mechanism 61 moves up and down inside the surrounding frame 21 together with the elevating base 37 by supporting the nozzle base 38 of the nozzle spray mechanism 61 on the elevating base 37 of the nozzle elevating mechanism 41. In order to reciprocate by traveling along the elevating base 37, the traveling path is moved along the left and right direction of the transport path 2 above the form S temporarily stopped inside the surrounding frame 21. .

(Nozzle elevating mechanism)
As shown in FIGS. 6, 8, and 9, the nozzle raising / lowering mechanism 41 includes a lifting / lowering motor 42 supported and fixed to a pair of base frames 36 disposed in front and rear, and a base that is driven and rotated by the lifting / lowering motor 42. The start ends of the pair of nozzle elevating sprockets 43A, 43B supported on the respective frames 36 and the nozzle elevating sprockets 43A, 43B themselves are connected to be wound or unwound by the nozzle elevating sprockets 43A, 43B, respectively. Nozzle elevating chains 44A and 44B are provided, which are suspended in the surrounding frame body 21 via a relay sprocket 45 supported on the base frame 36 and are connected to the pair of elevating bases 37, respectively.

  In the nozzle raising / lowering mechanism 41, the nozzle base 38 of the nozzle spray mechanism 61 is moved in the left-right direction of the transport path 2 so as to smoothly move and run. A pair of nozzle elevating sprockets 43A and 43B and a nozzle elevating chain 44A and 44B are arranged respectively, and the nozzle elevating chains 44A and 44B are connected in front and rear and right and left so as to be connected to the front and rear of the paired elevating base 37. It is composed of four. The nozzle elevating chains 44A and 44B are moved through the elevating guide holes 26 formed in the ceiling side wall 25 of the surrounding frame 21 by the relay sprockets 45 supported on the front, rear, left and right of the base frame 36. (See FIGS. 6 and 9).

  The pair of nozzle elevating and lowering sprockets 43A and 43B are supported side by side along the front-rear direction of the transport path 2 so as to be driven and rotated by the driving of the elevating motor 42. In one of the nozzle raising and lowering sprockets 43A, one of the nozzle raising and lowering chains 44A connected to one of the front and rear portions of the lifting and lowering base 37 is connected on the upper side, and the other nozzle raising and lowering sprocket 43B is connected. In the figure, the other nozzle elevating chain 44B connected to the other one of the front and rear portions of the elevating base 37 is connected at the lower side.

  In this way, for example, the driven rotation in the same direction of the nozzle lifting sprockets 43A, 43B, for example, in the forward direction, raises the lifting base 37 by winding the nozzle lifting chains 44A, 44B, and the driven rotation in the reverse direction is the nozzle rotation. By unwinding the lifting chains 44A and 44B, the lifting base 37 is lowered, and the nozzle moving mechanism 55 itself and the nozzle spray mechanism 61 are also raised and lowered. The nozzle elevating mechanism 41 is arranged in a pair configuration along the front-rear direction of the transport path 2, so that the paired elevating base 37 disposed in the front-rear direction can be smoothly tilted back and forth or left and right. Raise and lower while maintaining a substantially horizontal state.

  Adjustment of the elevation position of the nozzle base 38 or the elevation base 37 by the nozzle elevation mechanism 41 is set and controlled by height setting control means 46 so as to correspond to the height of the form S carried into the spray application area 20. You. As shown in FIGS. 9 and 10, the height setting control means 46 determines the different height positions corresponding to the different heights of the formwork S, the width of the formwork S in the unfolded state, and the like. A control panel 47 for instructing, an elevating positioning sensor 48 individually arranged, for example, along the nozzle support column 35 corresponding to the height position of the form S, and the elevating positioning so as to be detected by the elevating positioning sensor 48. A detection body 51 that slides along the direction in which the sensors 48 are arranged and is connected to an elevating control cable 49 such as a chain that has one end connected to the elevating base 37 and is pulled to follow the elevating base 37. When the detection body 51 reaches a predetermined position of the vertical positioning sensor 48 corresponding to the height position indicated corresponding to the height of the form S, the vertical movement is stopped. To composed.

  As shown in FIG. 11, the control panel 47 is corresponding to each of different height positions corresponding to the height of the form S, and further to indicate the width of the form S in the unfolded state. It consists of a panel on which a plurality of instruction buttons 47A are arranged, and is arranged, for example, on one side of the transport path 2 immediately before the spray application area 20, and is supported by a support post at a predetermined height position. (See FIGS. 2 and 5). The control panel 47 may be a touch panel type display device (not shown).

  A plurality of elevation positioning sensors 48 are provided at each height position corresponding to each of different heights of the form S along the vertical direction on the side surface of the nozzle support pillar 35 standing on the outside of the surrounding frame 21. The detectors 51 are arranged so as to detect the detection bodies 51 that slide up and down along the nozzle support columns 35. It should be noted that the upper elevation positioning sensor 48 corresponds to the lower form S, and the lower elevation positioning sensor 48 corresponds to the higher form S.

  The elevating control cable 49 is connected between the elevating base 37 inside the surrounding frame 21 and the vertically moving detecting body 51 guided along the nozzle support column 35 outside the surrounding frame 21. It is arranged in a folded shape by sprockets arranged on the upper ends of the left and right side walls 24 of the surrounding frame 21. In this way, the elevating operation of the elevating base 37 moves the detector 51 up and down in a direction opposite to the elevating direction, and moves the detector 51 downward when the elevating base 37 moves up. When the angle falls, the detection body 51 is moved upward.

  The detection body 51 is configured to be moved up and down by the elevating control rope 49 using the groove portion of the nozzle support column 35 formed of, for example, an H-section steel as a guide, and as described above, the height of the form S is set. The vertical position sensors 48 arranged in the vertical direction at positions corresponding to the vertical position are detected.

  Thus, when the nozzle elevating mechanism 41 operates and the detector 51 moves up and down via the elevating control cable 49 as the elevating base 37 elevates, the height position indicated by the control panel 47 is adjusted. When the detection body 51 reaches the position of the corresponding lifting / lowering positioning sensor 48, the lifting / lowering positioning sensor 48 detects the detection body 51, thereby stopping the lifting / lowering operation of the nozzle lifting / lowering mechanism 41, and setting the height of the form S. Is set at the spray height position of the nozzle 62 corresponding to.

(Nozzle moving mechanism)
As shown in FIGS. 6, 9, 12, and 13, the nozzle moving mechanism 55 is provided on a lifting base 37 which is raised and lowered in the surrounding frame 21 by the nozzle lifting mechanism 41. As shown in the drawing, the nozzle moving mechanism 55 is supported by a moving motor 56 disposed on the elevating base 37, and is hung on the elevating base 37 along the left and right direction of the transport path 2 so as to be driven and circulated by the moving motor 56. A moving chain 57 connected to the nozzle base 38 and a traveling guide means 39 formed by engaging a traveling roller supported on the upper portion of the nozzle base 38 in a guide rail provided on the elevating base 37. Become.

  The elevating base 37 is long in the left-right direction of the transport path 2 and is formed of, for example, a predetermined steel material in a rectangular frame shape in a plane, and is connected to the nozzle elevating chain 44A at positions near four corners of the elevating base 37. , 44B so as to ascend and descend while maintaining a substantially horizontal state without tilting forward, backward, left and right.

  The moving chain 57 is looped between the sprockets arranged at the respective ends of the lifting base 37 along the left and right direction of the transport path 2, and is guided by the lifting base 37 and travels by sliding. It is connected to at least one side of the base 38. The forward / reverse driven circulation of the moving chain 57 causes the nozzle base 38 of the nozzle spray mechanism 61 to reciprocate, for example, in the left-right direction of the transport path 2. One of them is on standby (see FIGS. 12 and 13).

(Nozzle spray mechanism)
As shown in FIGS. 5, 6, 9, and 14, the nozzle spray mechanism 61 is supported and connected to the elevating base 37 of the nozzle elevating mechanism 41, and is moved along the left and right directions of the transport path 2 by the nozzle moving mechanism 55. And a plurality of nozzle bases 38 arranged on the nozzle base 38, each spraying operation being controlled so as to spray a release agent supplied from a release agent tank (not shown). And a nozzle 62. The spraying operation from the nozzle 62 by the nozzle spraying mechanism 61 is performed by the spraying operation control panel 65 described later, which controls the number of spraying of the nozzle 62, the selection of the spraying operation site, and the like, and is performed by the movement by the nozzle moving mechanism 55. Usually, it is sprayed only at the time of forward movement, but if necessary, it can be performed at the time of backward movement.

  The nozzle base 38 itself is formed with a length that is not smaller than the maximum width of the form S that is temporarily stopped on the transport path 2 and is expanded in the unfolded state. The travel guide means 39 allows the vehicle to travel while being supported by the elevating base 37.

  The nozzles 62 are arranged in a straight line or in a staggered manner along the length direction of the nozzle base 38, and are arranged in a predetermined number, for example, 23 nozzles. The nozzle 62 itself is configured to spray the release agent in the form of a spray. The nozzle 62 is controlled to descend by the nozzle elevating mechanism 41 to a position corresponding to the height of the mold S, and then is moved by the nozzle moving mechanism 55. The spray operation is started as the vehicle travels. The spraying operation corresponds to the difference in size when the nozzle spray mechanism 61 moves from the standby position by the nozzle moving mechanism 55 because the deployed form S has a large difference or difference. With the control based on time and distance, the process is started at the time of reaching the position near one end of the mold S, and is ended at the time of reaching the position near the other end of the mold S. Spray coating.

  The spraying operation of the nozzles 62 is performed by the spraying operation control panel 65 shown in FIG. 16 so that the spraying operation of each of the nozzles 62 positioned and arranged on the nozzle base 38 is turned on or off. The setting is controlled in advance according to the state of the form S being set. That is, the planar shape of the expanded form S is, when the form S is expanded, for example, four-sided, in a so-called cross-shaped outer shape, from one side to the other along the expanding direction. In the case, when viewed from the plane being moved, the time at the start and end of the movement is narrow, and the width at the time of movement is wide. Therefore, the spray timing of each of the arranged nozzles 62 and the ON / OFF of the spray operation are appropriately determined. In this manner, efficient spray application can be performed without waste.

  Therefore, as shown in the figure, the spray operation control panel 65 is, for example, at the start of movement, ie, one side movement area, at the time of middle movement, ie, center movement area, and at the end of movement, ie, the other side, in the movement time zone / movement area. A panel panel is prepared which displays the number of nozzle display buttons 66 corresponding to the number of nozzles 62 arranged on the nozzle base 38 in correspondence with each of the partial movement areas, thereby enabling the selection of the spraying operation site to be controlled. The ON / OFF of the nozzle display buttons 66 can be instructed by, for example, a touch panel method.

  For example, when the number of nozzles 62 arranged on the nozzle base 38 is 23, and at the start of movement and in the spraying in one side moving area, the spraying is not required for the nozzles 62 on both sides, so only the nozzle display button 66 in the central part area is turned ON. At the time of midway movement / central movement area, the nozzle display button 66 of the number and position corresponding to the width in the expanded and deployed form of the form S is instructed to be ON, at the end of movement / at the start of movement at the other side movement area. Similarly, only the nozzle display button 66 in the central portion is turned ON. The spray operation control panel 65 controls the spray of each of the nozzles 62 and the control instruction of the stop thereof through an electromagnetic valve 63 attached to the nozzle base 38. Further, the instruction to the nozzle display button 66 on the spray operation control panel 65 is displayed as “○” in the ON instruction and “×” in the OFF instruction by repeatedly pressing and touching the position of each nozzle display button 66 so as to be inversely displayed. It is.

  The moving speed of the nozzle moving mechanism 55 corresponding to the height of the mold S is controlled and set in advance by an inverter or the like as three types, such as low speed, medium speed, and high speed. When it is ~ 150, it moves at high speed, when it is 300-500, it moves at medium speed, and when it is 750, it moves at low speed.

  The control panel 47 of the height setting control means 46 instructs the control of the vertical position of the nozzle raising / lowering mechanism 41 in accordance with the height of the mold S. The expansion and development form becomes wider and narrower in accordance with the height of the formwork S2, and accordingly, the number and position of the nozzles 62 to be sprayed also correspond to each other. In any case, since the mold S is relatively standardized, the nozzle device 40 has a nozzle spraying mechanism that turns on and off the spraying operation of the nozzles 62 arranged within a wide and narrow range corresponding to the standard. 61 is controlled.

(Contact avoidance means)
In the nozzle device 40 configured as described above, when the nozzles 62 arranged on the nozzle base 38 are positioned down by the nozzle elevating mechanism 41 to a predetermined height position, contact and collision with the form S are prevented. The contact avoiding means 71 is provided on the nozzle base 38. As shown in FIGS. 14 and 15, the contact avoiding means 71 is located below the lowermost position of the nozzle 62, and a detection wire 72 suspended between the ends of the nozzle base 38, An extension sensor 75 for detecting the presence or absence of extension is provided, and when the extension of the detection wire 72 is detected, the lowering operation of the nozzle elevating mechanism 41 is immediately stopped.

  The detection wire 72 is positioned below and in front of the nozzle base 38 via pulleys connected to the ends of the nozzle base 38, for example, at the ends of a bendable support bar 73. At least at one end, a coil spring 74 that is resiliently shrunk is connected.

  The extension sensor 75 detects the movement of the detection body 76 connected to the detection wire 72 in the vicinity of the coil spring 74. When the detection sensor 72 is lowered, it contacts, for example, the upper edge of the form S. By detecting the movement of the detector 76 when it is extended together with the coil spring 74, the lowering operation of the nozzle raising / lowering mechanism 41 is immediately stopped assuming that it comes into contact with the form S.

(Exhaust mechanism)
The surplus oil smoke of the release agent, which is not spray-applied to the mold S but is filled in the interior of the surrounding frame 21 by the spraying operation of the release agent by the nozzle device 40, is discharged to the exhaust mechanism 80 attached to the surrounding frame 21. Exhausted to the outside. As shown in FIGS. 1 and 5 to 7, the exhaust mechanism 80 includes an exhaust port 81 formed at a lower portion of a side wall of the surrounding frame body 21, for example, a lower portion of the left and right side walls 24, and an exhaust duct connected to the exhaust port 81. 82 and an exhaust fan 83 arranged on the outlet side of the exhaust duct 82.

  In the illustrated example, the exhaust duct 82 is disposed on the upper surface of the ceiling side wall 25 of the surrounding frame 21 so as to be directly connected to the exhaust port 81, and to be connected to the intake portion. And a horizontally arranged air supply portion communicating with a predetermined exhaust place.

(Processing flow)
Next, an example of the use of this will be described. The concrete material filled in the form S fixed to the carrier 10 is cured, and after the concrete product C is solidified, the carry-in area 3 is set for each carrier 10. And sequentially conveyed to the next processing area on the conveyance path 2. In each processing area, the positioning holes 11 provided in the transfer table 10 are detected by the transfer table positioning sensor 13 to stop at the center position of each processing area.

  In the product take-out area 4, the form S is disassembled and deployed on the carrier 10, which is fixed so as not to move by the stopper 12 fitted into the positioning hole 11, and the concrete product C such as a buried box is removed from the form S. And transfer it to the designated storage location. The transport table 10 and the mold S after being taken out are transported to the cleaning area 5, where the mold S is cleaned, and then transported to the spray application area 20.

  In the spray application area 20, the opening / closing gate 27 is at the raised position, and the entrance and the exit of the surrounding frame 21 are opened. Along with the loading, the control panel 47 selects and instructs an instruction button 47A corresponding to the height of the form S and the like, and sets and instructs the elevation height position of the nozzle elevating mechanism 41. Note that this instruction setting is maintained unless another instruction button 47A is selected by carrying in a mold S having a different height or the like.

  When the setting of the spray height position corresponding to the form S is instructed, the opening / closing gate 27 is lowered to close the surrounding frame 21 and the elevating base 37 is moved up and down by the nozzle elevating mechanism 41 so that the form S The nozzle stops at a position corresponding to the height position or the like, and the nozzle base 38 of the nozzle spray mechanism 61 is held. At this time, if the nozzle base 38 descends without stopping at the indicated height position, the contact avoiding means 71 comes into contact with the form S, thereby urgently stopping the descending operation of the nozzle elevating mechanism 41. By being warned, a predetermined avoidance processing operation is performed.

  When the vertical movement is stopped at the spray height position instructed by the control, the spray operation by the nozzle spray mechanism 61 is started with the movement set at a predetermined speed by the nozzle moving mechanism 55, and the spray selected by the spray operation control panel 65. In addition to the number of nozzles 62 to be sprayed, the positions of the nozzles 62 to be spray-operated, and other control instructions, the mold release agent is spray-applied to the form S in accordance with the height, width, form of development, and the like. The surplus oil smoke that has been spray-coated on the mold S inside the surrounding frame 21 in this manner is discharged to the outside of the surrounding frame 21 by the exhaust mechanism 80.

  When the spray application is completed, the nozzle moving mechanism 55 returns the nozzle spray mechanism 61 to the original position and waits for the nozzle spray mechanism 61 to prepare for the next operation, and opens the opening / closing gate 27 by the gate opening / closing mechanism 31. By opening the opening / closing gate 27, the mold S on which the spray application has been completed is transported together with the transport table 10 to the rebar loading area 6 in the next process, while the cleaned form S from the cleaning area 5 is transported by the transport table 10. It is carried into the surrounding frame body 21 and prepares for spray coating. The form S transported to the reinforcing bar loading area 6 is locked after a predetermined reinforcing bar S3 is loaded.

  Next, it is conveyed to the filling area 7 through the traverser 9 and is charged and filled with new concrete material. Thereafter, it is steam-cured through the unloading area 8 in a curing building or factory for a predetermined period of time, for example, 12 to 24 hours. It is like that.
