[0019]
The operation of the paste kneading apparatus as described above will be described in summary. The container receiving means 12a of the first paste delivery mechanism 4a has a first container 86a containing a base paste (shown by a solid line in FIG. 2). A second container 86b containing a hardener paste is attached to the container receiving means 12b of the second paste delivery mechanism 4b. When mounting the first container 86a and / or the second container 86b, the cover 10 of the housing 2 is placed in the open position shown by a two-dot chain line in FIG. The lid member 20a of the container receiving means 12a in the first paste delivery mechanism 4a and / or the lid member 20b of the container receiving means 12b in the second paste delivery mechanism 4b are brought to the open position shown by a solid line in FIG. As shown in FIGS. 2 and 3, the first and second containers 86 a and 86 b are relatively rigid mouth-neck portions 88 a and 88 b and an appropriate synthetic resin sheet or film that can be formed from an appropriate synthetic resin. The main parts 90a and 90b can be formed from such a flexible material, and a base paste and a hardener paste are accommodated in the main parts 90a and 90b, respectively. In the illustrated first and second containers 88a and 88b, the mouth-and-neck portions 88a and 88b are positioned so as not to be aligned with the central axes of the main portions 90a and 90b. The first and second containers 86a and 86b have the neck and neck parts 88a and 88b that are biased by removing caps (not shown) attached to the mouth and neck parts 88a and 88b. 88b is entered from above into notches 34a and 34b formed on one side of the front end walls 24a and 24b of the container receiving means 12a and 12b, and the main portions 90a and 90b are positioned in the box-shaped bodies 18a and 18b. The tips of the mouth and neck portions 88a and 88b extending forward through the cutouts 34a and 34b of the front end walls 24a and 24b are connected to the connecting members 38a and 38b, and thus the first and second containers 88a and 88b have a first inside. The first and second paste channels 40a and 40b are communicated with each other. After mounting the container receiving means 12a and 12b as required in this way, the lid members 20a and 20b of the container receiving means 12a and 12b are returned to the closed position shown by the two-dot chain line in FIG. Return to the closed position shown by the solid line in FIG.
[0020]
When the base paste and the hardener paste are kneaded and used, the operation button 92 disposed on the front surface of the housing 2 is pressed. As a result, the rotational drive source 76a in the first paste delivery mechanism 4a is energized, and the male screw member 52a is rotated in a predetermined direction, whereby the side wall 30a is moved in a direction approaching the side wall 26a. Accordingly, the main portion 90a of the first container 86a is crushed in the container receiving means 12a, whereby the base paste is sent to the paste flow path 40a through the mouth / neck part 88a of the first container 86a, and the paste flow path 40a. To the kneading means 6. Similarly, the rotational drive source 76b in the second paste delivery mechanism 4b is also urged to rotate the male screw member 52b in a predetermined direction, thereby moving the side wall 30b closer to the side wall 26b. Accordingly, the main portion 90b of the second container 86b is crushed in the container receiving means 12b, whereby the hardening material paste is sent to the paste flow path 40b through the mouth-neck part 88b of the second container 86b, and the paste flow path 40b. To the kneading means 6. Delivery of the paste from the first and second containers 86a and 86b is accomplished by moving the side walls 30a and 30b toward the opposing side walls 26a and 26b and crushing the main portions 90a and 90b of the containers 86a and 86b. Therefore, the paste can be stably delivered over a long period of time, and no serious problem occurs even if air is mixed into the first and second containers 86a and 86b. The amount of the base paste and the amount of the hardener paste supplied to the kneading means 6 is required to be, for example, about 2 to 3: 1. Therefore, in the illustrated embodiment, the side wall in the first paste delivery mechanism 4a is required. The moving speed of 26a is set to about 2 to 3 times the moving speed of the side wall 26b in the second paste delivery mechanism 4b. The moving speed of the side walls 26a and 26b is based on the rotational speed of the rotational drive sources 76a and 76b based on the detection value of a pressure detector (not shown) that detects the pressure of the paste in the paste flow paths 40a and 40b, respectively. It can be adjusted by controlling. The base paste and the curing material paste supplied to the kneading means 6 are mixed in the kneading means 6 and discharged from the tip of the casing 8 of the kneading means 6. When the pressing of the operation button 92 is released, the rotational drive sources 76a and 76b are deenergized, and the movement of the side walls 30a and 30b is stopped. If desired, after the movement of the side walls 30a and 30b is stopped, the side walls 30a and 30b are moved in the opposite direction to release the pressure that can remain in the first container 86a and the second container 86b, that is, the residual pressure. It is also possible to move it back slightly.
[0021]
The kneading of the base paste and the hardener paste is repeatedly performed. Therefore, the side wall 30a of the first paste delivery mechanism 4a is repeatedly moved in the direction indicated by the arrow 80a, and the side wall 30a is shown by a two-dot chain line in FIG. When it is moved to the final position shown, a detector (not shown) detects this, a warning lamp 94a disposed on the front surface of the housing 2 is turned on, and the base paste in the first container 86a is turned on. The user is warned that is exhausted. In this case, the reset button 96a disposed on the front surface of the housing 2 is pressed to urge the rotational drive source 76a to rotate the male screw member 52a in the opposite direction, and the side wall 30a is shown by a solid line in FIG. Return to the initial position. Next, the cover 10 of the housing 2 is opened, the lid member 20a of the container receiving means 12a is set to the open position, and the first container 86a is replaced with a new one. Similarly, when the side wall 30b of the second paste delivery mechanism 4b is moved to the final position indicated by a two-dot chain line in FIG. 2, a detector (not shown) detects this and is arranged on the front surface of the housing 2. The provided warning lamp 94b is turned on to warn the user that the hardener paste in the first container 86b has been exhausted. In this case, the reset button 96b may be pressed to replace the second container 86b with a new one in the same manner as the first container 86.
