Description

[0001]
BACKGROUND OF THE INVENTION
More specifically, the present invention relates to a liquid material application apparatus including a compact and easy-to-handle work supply apparatus that supplies a plurality of works stored in a magazine one by one to the main body of the application apparatus.
[0002]
[Prior art]
A workpiece supply device in a conventional liquid material application device places two magazines on one magazine table that can move in the Z (vertical) direction and the Y (front / back) direction, and a workpiece conveyance rail (X (left / right) direction). On the other hand, while the work in one magazine is being discharged, it moves in the Z direction. When all the work in one magazine has been discharged, the table moves in the Y direction and the work has not been discharged. The workpiece is supplied from the magazine to the workpiece conveyance rail.
[0003]
[Problems to be solved by the invention]
Such a workpiece supply device of the conventional liquid material coating device is large in size, and when exchanging a magazine arranged on the back side, the magazine must be lifted and then moved past the front magazine. In addition to being difficult to replace, there was a risk of colliding with the front magazine or dropping it on the front magazine.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid material applicator provided with a work supply device that is compact and easy to replace a magazine.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the liquid material application apparatus of the present invention applies the work housed in the magazine by moving up and down the applicator main body for applying the liquid material to the work and the magazine table on which the magazine is placed. A loader to be supplied to the apparatus main body, and a magazine table on which the magazine is placed are moved up and down, and an unloader for storing the work discharged from the application apparatus main body in the magazine, and on both sides of the application apparatus main body, An apparatus configuration in which a loader and an unloader are arranged, wherein the loader and unloader have a plurality of magazine tables arranged in a vertical direction.
[0006]
The magazine table of the loader and the magazine table of the unloader move in the vertical direction in conjunction with the operation of one feed screw of each of the loader and unloader, and the magazine table of the loader and the magazine of the unloader The table moves while keeping the relative distance between the magazine tables always constant, and the loader pushes the side surface of the work stored in the magazine to supply the work to the coating apparatus main body. It has a pusher portion, and the pusher portion can adjust the position where the arm of the pusher portion comes into contact with the side surface of the workpiece so as to be a position suitable for the size of the workpiece.
[0007]
Furthermore, in order to solve the above-described problems, the liquid material coating apparatus according to the present invention is configured such that the loader and the unloader transport a workpiece through a coating apparatus body having a workpiece transportation rail longer than the outer width of the coating apparatus body. The loader and the unloader are arranged so that the side surface of the magazine table does not protrude ahead of the front front end position of the coating apparatus main body. When replacing the magazine, the magazine table is moved to a predetermined replacement position. It is characterized in that the magazine can be exchanged even when the coating apparatus main body is in operation.
[0008]
[Action]
Of the magazines placed on the upper and lower magazine tables, the workpieces are supplied in order from the workpiece stored in the lowermost magazine of the lower magazine until the magazine stored in the uppermost magazine table is discharged. After lowering at the pitch of the workpieces stored in the magazine and discharging the workpiece stored in the uppermost magazine of the lower magazine, it is further lowered to the position of the workpiece stored in the lowermost magazine of the upper magazine, After the work stored in the lowermost stage is discharged, it is lowered at the pitch of the work stored in the magazine in the same manner as the lower magazine.
[0009]
【Example】
One embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to this embodiment.
[0010]
Liquid material applying apparatus of the present invention, as shown in FIG. 1, the coating apparatus main body 10 for applying a liquid material to a work, which is located on the side of the coating apparatus main body 10, the magazine table for placing the magazine 40 The loader 20 that feeds the work stored in the magazine 40 to the coating apparatus main body 10 and the magazine table on which the magazine 40 is placed are moved up and down, and the work is discharged from the coating apparatus main body 10. And the unloader 30 for storing the magazine in the magazine 40.
[0011]
"magazine"
The magazine 40 used by being mounted on the magazine table of the liquid material applicator of the present invention is a rectangular parallelepiped case, and two faces facing each other among the four faces serving as side faces are open, The wall surface is provided with a groove from one open surface to another open surface, and a plurality of grooves 41 are provided in the vertical direction so that the workpiece slides. It is stored in.
[0012]
<Applicator body>
The coating apparatus main body 10 shown in FIG. 1 has a workpiece conveyance rail 12 longer than the outer width of the coating apparatus main body 10, and conveys a workpiece from the loader 20 to the unloader 30 via the coating apparatus main body 10.
In the coating apparatus main body 10, a work transport rail 12 is disposed across the coating apparatus main body 10, and a coating work area is provided in the middle of the work transport rail 12 .
The surface of the workpiece conveyance rail 12 conveys the workpiece to the application work area by a mechanism such as a belt conveyor.
[0013]
"Loader and unload da"
A plurality of magazines 40 are placed on the magazine table 21 of the loader 20 and the magazine table 31 of the unloader 30. The magazine table 21 of the loader 20 and the magazine table 31 of the unloader 30 are each magazine table 21. , 31 while keeping the relative distance between them constant.
[0014]
The loader 20 and the unloader 30 arrange the loader 20 and the unloader 30 so that the side surface of the magazine table does not protrude before the front front end position of the coating apparatus main body 10.
Further, the loader 20 and the unloader 30 are configured such that when the magazine 40 is replaced, the magazine 40 can be replaced even when the magazine tables 21 and 31 are moved to preset replacement positions and the coating apparatus main body 10 is operating.
[0015]
The magazine table 21 of the loader 20 and the magazine table 31 of the unloader 30 are intermittently raised by the work storage pitch in conjunction with the completion of the application in the application apparatus main body 10 , and the magazine on the magazine table 21 of the loader 20 is at the stop position. The workpieces in 40 are smoothly supplied from the magazine 40 to the application work position of the application apparatus main body 10, and the applied work at the application work position of the application apparatus main body 10 is transferred to the magazine 40 on the magazine table 31 of the unloader 30.
