[0073] like Figures 1 to 8 As shown, the present invention provides an automatic filling device with a spray gun library, which includes a modular spray gun library 10, a transplanter 20, and a filling host 30. The filling host 30 is arranged side by side with the spray gun library 10, and the transplanter 20 is mounted on the filling host 30. The filling host 30 places a spray gun 40 on the transplanter 20, which then places the spray gun 40 into the corresponding spray gun library 10. The spray gun library 10 is then translated to move the spray gun 40 to a position to be replaced. The transplanter 20 then picks up the spray gun 40 and exchanges it with the Z-axis servo axis 31 of the filling host 30. The transplanter 20 is preferably mounted below the filling host 30, opposite the spray gun library 10.

[0074] Preferably, the spray gun storage 10 includes a base 11 and multiple gun storages 12, each of which is mounted side by side on the base 11. Each gun storage 12 includes a frame 121, a partition net 122, a first detection switch 123, and a fixing plate 124. The frame 121 is mounted on the base 11, the partition net 122 is mounted on the corresponding frame 121, and the fixing plate 124 is mounted on the frame 121, located at the front end of the partition net 122, for fixing the spray gun 40. The first detection switch 123 is mounted on the fixing plate 124 for detecting the presence of a spray gun. The fixing plate 124 is preferably a U-shaped fixing plate.

[0075] Furthermore, the gun storages 12 are connected by a pull bolt 50. A second detection switch 125 is installed at the lower portion of the frame 121 for feeding back the tension state of the pull bolt 50.

[0076] Preferably, the transfer machine 20 includes a vertical support rod 21, a horizontal mounting frame 22, a horizontal motion cylinder 23, a plurality of first position detection switches 24, a vertical motion cylinder 25, a plurality of second position detection switches 26, a vertical positioning pin 27, and a spray gun detection switch substrate 28. The horizontal mounting frame 22 is mounted on the vertical support rod 21, the horizontal motion cylinder 23 is mounted on the inner side of the horizontal mounting frame 22, and the first position detection switch 24 is mounted on the horizontal mounting frame 22 and the horizontal motion cylinder 23. The vertical motion cylinder 25 is mounted on the lower portion of the vertical support rod 21, and the second position detection switch 26 is mounted on the vertical support rod 21 and the vertical motion cylinder 25. The spray gun detection switch substrate 28 is mounted on the top of the vertical support rod 21, and the vertical positioning pin 27 is mounted on the spray gun detection switch substrate 28.

[0077] Furthermore, a Z-direction servo shaft 31 and a spray gun clamping device 32 are provided on the filling host 30 . The spray gun clamping device 32 is installed on the Z-direction servo shaft 31 for installing the spray gun 40 .

[0078] The spray gun 40 is mounted on a spray gun seat 41. The spray gun seat 41 is provided with a plurality of vertical positioning pin holes 411 and a plurality of T-shaped rivets 412. The locating pin holes 411 are matched with the vertical positioning pins 27. The T-shaped rivets 412 are preferably horizontal.

[0079] As described above, the automatic filling device with a spray gun storage system of the present invention relates to liquid product filling equipment, particularly for filling multiple different materials without sharing spray guns. The automatic filling device with a spray gun storage system includes a transfer mechanism mounted on a frame, a spray gun storage system, and a filling machine. The user can configure automatic spray gun exchange as needed. The filling machine first places the spray gun on the transfer mechanism, which then places the gun into the corresponding spray gun storage system. The storage system then translates the desired gun to a predetermined replacement position. The transfer mechanism then picks up the gun and exchanges it with the filling machine's Z-axis servo axis. The spray gun storage system consists of two main parts: a gun storage system and a base. The gun storage system is further divided into a frame, a partition net, a detection switch, and a U-shaped fixing plate. The gun storage systems can be connected by a pull bolt 50, with a third detection switch 125 providing feedback on the tension status. This allows the number of gun storage systems to be customized. Material hoses are separated by a partition net 122 into separate compartments, preventing them from interfering with each other.

[0080] The present invention also provides a method for automatically changing spray guns, which adopts the automatic filling device with a spray gun library as described above. The user can choose to set the automatic spray gun changing method according to needs. The filling host first places the spray gun on the equipment on the transplanter, and the transplanter then places the spray gun into the corresponding spray gun library. The spray gun library moves the required spray gun to the to-be-determined spray gun changing position, and the transplanter picks up the spray gun and exchanges it with the Z axis of the host.

[0081] Preferably, the method for automatically changing the spray gun comprises the following steps:

[0082] Step S1: The operator switches the filling machine operation mode to "automatic gun change", displays the current "gun 1", selects "gun 2" to be switched, and presses the "start button";

[0083] Step S2, the filling host detects that there is no spray gun on the transplanter, there is no spray gun in the first gun warehouse, and there is a spray gun in the second gun warehouse;

[0084] In step S3, the equipment moves to the top of the transplanter and places the spray gun on the transplanter, and the Z axis of the filling host is disengaged.

[0085] Further preferably, after step S3, the method for automatically changing the spray gun further comprises:

[0086] Step S4, the spray gun library is translated to move the first gun library to the gun changing position;

[0087] Step S5, the transplanter carries spray gun 1 and extends it above gun storage 1. The transplanter descends and spray gun 1 is hooked into gun storage 1. The transplanter continues to descend until it is released, and then the transplanter retracts.

[0088] Step S6: the spray gun library is translated to move the second gun library to the gun changing position.

[0089] More preferably, after step S6, the method for automatically changing the spray gun further comprises:

[0090] Step S7, the transplanter extends to the bottom of the second gun storage, the transplanter rises and the positioning pin is inserted into the positioning pin hole of the second spray gun, the transplanter continues to rise until the second spray gun is separated from the second gun storage, and the transplanter retracts;

[0091] Step S8: The Z-direction servo axis of the filling host picks up the second spray gun and moves it to the filling position.

[0092] At this point, the automatic switching between spray gun 1 and spray gun 2 is completed.

[0093] In summary, the present invention's automatic filling device with a spray gun storage and its automatic spray gun replacement method install the spray guns in a storage outside the device. When a gun needs to be replaced, it can be replaced using a spray gun transplanter. This eliminates the need for replacement spray guns to occupy space within the device, and the material hoses are restrained within the storage, preventing them from rubbing against each other. The number of spray guns can be freely adjusted based on demand.

[0094] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
