Description

[Detailed explanation of the invention] This invention uses caulking material, sealing material, etc. for the joints of flooring materials, etc.
This invention relates to an automatic filler injection machine used for filling fillers such as adhesives.

Conventionally, as shown in FIG. 1, a metal nozzle 33 is attached to a cap 32 of a plastics container 31, the plastics container 31 is filled with a filler, and the metal nozzle 33 is inserted into a seam 35 of a flooring material 34. , press the plastics container 31 with your hand 36 to force the filling material from the metal nozzle 33 into the filling material 37
The filling material 37 was injected into the seam 35 by pushing it out and pulling it toward you (in the direction of the arrow).

However, such manual work must be performed in a bent-down position, and since the filling material 37 often has a high viscosity, the plastic container 31 is pushed by hand to force the filling material 37 through the nozzle 33.
A considerable amount of grip strength is required to force the nozzle 33 out of the joint 35, and a considerable degree of skill is required to prevent the nozzle 33 from coming off the joint 35. This greatly affects the variation in the amount of filler 37 applied.

The purpose of this invention is to mechanize the conventional manual work that requires a lot of labor and has many variations. A drive device for driving the wheels, a filling material container to which a nozzle is connected, and, if desired, a pressure device for applying pressure to the filling material container, etc. are placed on a cart to which wheels are attached.
In this way, only one main wheel is driven by the drive device, and the center of gravity of the main body is located approximately on the axis of the pair of main wheels, and the nozzle has a guide portion protruding from one side of the nozzle hole, so that the nozzle and the main body move forward. The angle θ between the direction and the floor is 9
The main idea is to automate the filling material injection work using an automatic filling material injection machine that is characterized by setting the nozzle at an angle of 0° or more.

The present invention will be explained with reference to an embodiment shown in FIG. A drive device 15 for driving the main wheels 12A via a chain 14 and a compressor 16 are installed at the rear of the drive device 15, and the drive device 15 and the compressor 16 are operated by electric current from a lead wire 17.

As the drive device 15, a variable speed electric motor whose rotational speed is remotely controlled by phase control or voltage control is used.

A pressure pipe 19 with a valve 18 interposed therebetween is connected to the compressor 16 and connected to a filler container 20 .

A pressure feed pipe 21 connected to the nozzle 1 is connected to the filler container 20 via a valve 22, and a pressure gauge 23 is further connected to the top surface of the filler container 20.

Note that a cover 24 is provided over the drive device 15 and the compressor 16.

Next, details of the structure of the nozzle 1 are shown in FIGS. 3 to 5.

In the nozzle 1, there is a small insertion part 1B at the bottom of the base part 1A.
form.

2 is a hole provided in the nozzle 1, and 3 is a guide hole continuous from the bottom of the hole 2, which is opened at the lower end of the nozzle 1 to form a nozzle hole 4.

A guide portion 5 is made to protrude from one side of the nozzle hole 4.

In the nozzle 1, the angle θ formed by the guide portion 5 and the boundary step surface 1C between the base portion 1A and the insertion portion 1B is smaller than 90°, preferably larger than 40°.

In the automatic filler injection machine, when the compressor 16 is driven and the valve 18 is opened, pressure is transmitted to the filler container 20 via the pressure pipe 19, and the filler 6 filled in the filler container 20 is pushed out. When the valve 22 is opened, the filling material 6 is forced out from the nozzle 1 through the pressure pipe 21.

If the drive device 15 is driven at the same time, the main wheels 12A will rotate via the chain 14, and the automatic filler injection machine will move in the direction of arrow A.

At this time, the boundary step surface 1C between the base portion 1A and the insertion portion 1B of the nozzle 1 is in close contact with the floor surface as shown in FIG. °,
Desirably, the angle is such that θ'<140°.

In this way, the nozzle 1 receives the downward force due to the wedge effect of the guide portion 5, and as shown in FIG.
Since the nozzle 1 moves forward and moves forward, the nozzle 1 does not float up and come off the joint 8.

In this way, the automatic filler injection machine has the most advanced nozzle 1 at the seam 8.
Direction can be given by following reliably.

In order for the main body to smoothly follow the orientation of the nozzle 1, it is sufficient to transmit the driving force to only one main wheel 12A.

This is because when the driving force is transmitted to both main wheels 12A and 12B, as shown in Fig. 8, when the nozzle 1 reaches the curve 9 of the seam 8 and is to carve to the left, the automatic filler injector will move to the left. The main wheel 12A will rotate slightly.
, 12B are the same, so the automatic filler injection machine tries to maintain linear motion, and the torque in the opposite direction to the above rotation is applied, so the automatic filler injection machine Rotation does not occur smoothly.

The center of rotation of the automatic filler injection machine is the main wheels 12A, 12.
If the center part 12 of B is made to substantially coincide with the center of gravity of the automatic filler injector, the automatic filler injector will rotate more smoothly.

In this way, the joint 8 is filled with the filler 6 as shown in FIG. 6, but it is desirable to adjust the amount of the filler 6 depending on the width of the joint 8.

The amount of filling material 6 can be adjusted most easily by adjusting the moving speed of the automatic filling material injection machine.

That is, if the moving speed is made small, the filling amount of the filler 6 becomes large, and if the moving speed is made large, the filling amount of the filler 6 becomes small.

The movement speed control is performed remotely by phase control or voltage control of the drive device 15 as described above.

Other than this embodiment, any number of wheels may be attached to the truck, but only one wheel is driven by the drive device.

Further, the pressure device may be separated from the main body and connected to the filler container through a flexible pipe or the like.

As described above, the present invention is applied to a nozzle having a nozzle hole at its tip, and a guide portion is made to protrude only on one side of the nozzle hole, and the angle between the nozzle and the floor surface in the direction of movement is set at 90 degrees or more. Due to the wedge effect of the guide part, the nozzle receives a downward force as it moves forward, and enters the joint and moves forward by 9 degrees, so that the nozzle does not come off the joint.

At the same time, the guide portion prevents flooring chips and debris from clogging the nozzle hole.

Furthermore, since only one of the pair of main wheels is driven by the drive device, the left and right rotation of the main body is extremely smooth, and the center of gravity of the main body is located approximately on the axis of the main wheel. Since the center of rotation of the main body and the center of gravity of the main body are made to substantially coincide with each other, the rotation of the main body can be performed even more smoothly.

In this way, the nozzle reliably follows the joint without coming off the joint, and the main body can easily rotate left and right and follow the left and right movement of the nozzle, making it easy to inject the filler using the injector of the present invention. This will be done automatically and accurately.
