Description

[Detailed description of the invention] [Industrial application field] This proposal relates to an automatic spraying device that sprays foamed resin agents such as heat insulating materials or paints onto vertical walls and ceilings, and is suitable for use in heat and cold insulation work, painting work, etc. It is used in fields such as

[Conventional technology]

BACKGROUND ART Conventionally, a paint gun has been generally used to spray a foamed resin agent, paint, or the like onto the wall surface, ceiling surface, or the like. In this method, the foamed resin agent or the like is ejected from the nozzle of a painting gun and sprayed onto a wall surface, ceiling surface, etc.

[Problems that this invention attempts to solve]

However, with conventional paint guns, you hold the handle and move it back and forth from side to side while spraying from the top to the bottom of the wall, so if the surface to be sprayed is high and wide, you can use a stepladder or the like to keep it constant. It is a complicated task to go up and down the area to spray, then move a stepladder etc. to the next area and go up and down in the same way while spraying.Especially when the spraying surface is extremely high or the ceiling, Spraying work was difficult and work efficiency was low.

[Means for solving problems]

This project is an attempt to solve the above problem, and a holder frame is attached to a support that can be disassembled and erected on a moving truck so that it can move up and down, and a support plate that is fixed to one side of the frame is attached. A swing motor is attached and connected to the eccentric shaft, and the eccentric shaft is connected to a holding plate which is pivotally connected to the support plate with a fulcrum shaft at the approximate center, and a rotating motor is connected to the tip of the holding plate. The shaft is connected to a swinging motor installed on a holding plate so that it can be rotated back and forth, and a holding arm is fixed to the rotating shaft, and a coating gun is detachably attached to the holding arm.

[Effect]

For convenience of explanation, the operation of the present device having the above-mentioned configuration will be explained based on the drawings of the embodiment and with reference to the reference numerals.

In this device, first, rails 11 and 11a are installed parallel to the surface to be sprayed, the operating screw 14 is turned to extend the supporting legs of the caster 13, and the trolley 1 is moved so that the wheels 2 and 2a of the trolley 1 are placed on the rails. After that, the supporting legs of the caster 13 are retracted and the wheels are placed on the rail. Further, the support column 15 is fixed to the trolley 1 by clamping the clamp mechanism 17 to suppress the upper surface of the substrate 16, and the painting gun 38 is detachably attached to the holding arm 36 by turning the tightening handle 37. I'll keep it.

When the lifting motor 23 is operated in this manner, the gear 20 meshing with the rack 21 provided vertically on one side of the support column 15 rotates, and the holder frame 18 moves upward or downward. Therefore, the support plate 25, the holding plate 28, and the painting gun 38 also move up and down together, and the painting gun 28 can be set at a spraying position at a desired height.

Next, when the swing motor 26 is driven, the holding plate 28 connected to the eccentric shaft 27 reciprocates from side to side about the fulcrum shaft 29, and the painting gun 38 also reciprocates from side to side, so that the same height is maintained. Spraying is carried out repeatedly at the position.

Further, when the swing motor 33 is operated, the rotating shaft 31 is rotated in the selected direction via the chain 35, so that the painting gun 38 attached to the holding arm 36 also changes its spray angle upward or downward. (shown by the dashed line in FIG. 1).

In this way, after spraying in a certain range from high to low on the surface to be sprayed, the trolley 1 can be moved to spray the next range. For areas that require spraying, it is possible to remove the paint gun 38 by turning the tightening handle 37, hold it in your hand, and spray the area.

Furthermore, to spray on the ceiling surface,
The clamp mechanism 17 is released, the support 15 is rotated 90 degrees to align the painting gun 38 with either side of the traveling direction of the trolley 1 (as shown by the dashed line in FIG. 2), and the support 15 is rotated by the clamp mechanism 17 again. is fixed, and the coating gun 38 is set upward. Thereby, while the trolley 1 is running on the rails, the above-mentioned upward painting gun 38 can be reciprocated from side to side to spray onto the ceiling surface.

Further, suspension plates 12 are attached to the front and rear parts of the trolley 1, and casters 13 are attached to both ends of the suspension plates 12, respectively.
The supporting legs of the caster are fixed on the upper surface of the suspension plate so that they can be adjusted in height by operating screws 14, and when the supporting legs are extended, the trolley 1 lifts up from the rails 11, 11a and separates from the rails 11, 11a.
It is designed so that it can be moved.

Reference numeral 15 denotes a support in the form of a square pipe, and its height can be set to a desired height by connecting the square pipe and a rack to be described later. The pillar 15
is fixed to the trolley 1 by applying a substrate 16 integrally provided at the bottom to the upper surface of the truck 1 and restraining the upper surface of the substrate 16 with a plurality of clamp mechanisms 17 fixedly provided on the truck. There is. The clamp mechanism 17 has a configuration similar to that used conventionally, and by releasing this restraint, the support column 15 can be removed from the truck 1 or its angle can be changed.
