[0094] It should be noted that in the technical solution where the automatic container identification spraying system is applied to spray an identification on the side plate of a container, the first direction is the length direction of the container, and the second direction is the width direction of the container. In the technical solution where the automatic container identification spraying system is applied to spray an identification on the end of a container, the first direction is the width direction of the container, and the second direction is the length direction of the container. The first direction is perpendicular to the second direction. The height direction is perpendicular to the first direction and the second direction.

[0095] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0096] As shown Figure 1 in the figure, the container 100 generally may include main structures such as a top plate 101, side plates 102, a chassis 103, and ends. The container 100 may include two ends oppositely arranged in a first direction. Larger trademarks and other markings usually need to be sprayed or pasted on the ends or side plates 102 for easy user identification. The two ends of the illustrated container 100 may include a front end 104 and a door end 105, and a door may be provided at the door end 105. Of course, the automatic container marking spraying system according to the present application may also be applicable to a side-opening container, that is, a door is provided on the side plate 102, and no door needs to be provided at the two ends of the container.

[0097] As shown Figure 1 in Figure 2 the figure, in a preferred embodiment, an automatic container marking spraying system 200 includes: a spraying chamber 201, a spraying device 202, and a marking mold fixing device 206;

[0098] The inside of the spraying chamber 201 can accommodate the container 100. The spraying chamber 201 provides shielding for the marking operation to form a closed or semi-closed working environment and avoid paint and gas from polluting the external environment. The container 100 to be marked moves into the inside of the spraying chamber 201 for marking spraying and then moves away from the spraying chamber 201 after the marking spraying is completed;

[0099] The spraying device 202 is arranged inside the spraying chamber 201 and on the side of the container 100. The spraying device 202 is provided with a spray gun 205. The spray gun 205 can move along the height direction and the first direction of the container 100. In the figure, the height direction of the container 100 is the Z-axis direction, and the first direction is the X-axis direction. Moving in these two directions can form markings of a certain area in the form of text or patterns. The moving mode is reciprocating movement, which can provide sufficient paint spraying volume to ensure the quality of the formed markings and avoid insufficient paint spraying volume at a certain part of the marking, which may affect the shape of the marking. The opening and closing speed of the spray gun 205 can be controlled by servo pulses to ensure the spraying of markings of different sizes and shapes.

[0100] The marking mold fixing device 206 can abut the marking mold 300 against the side plate 102 of the container 100, and the spray gun 205 can spray paint towards the marking mold 300 to form a marking on the side plate 102 of the container 100. It can be understood that Figure 1The shape of the logo in it (the Chinese character "trademark") is only exemplary. In this application, the shape of the logo is not specifically limited. The logo mold 300 is designed according to the logo to be sprayed, and is usually set as a hollow structure. The logo mold 300 may include a logo mold body and a hollow part provided on the logo mold body. The hollow part can allow the paint to pass through, so as to form a logo on the side plate 102 of the container 100. After the logo spraying is completed, the logo mold fixing device 206 can also move the logo mold 300 away from the side plate 102 of the container 100.

[0101] The automatic container logo spraying system 200 in this embodiment can automatically spray logos (abbreviated as logo spraying for short) on the side plate 102 of the container 100, replacing manual logo spraying, meeting the logo spraying needs of various container types, meeting the spraying needs of logos of different sizes and shapes, improving the logo spraying efficiency, ensuring the logo spraying quality, and effectively reducing the production cost.

[0102] The front end 104 of the container 100 may include an end plate, and the end plate may be connected between two corner posts along the second direction. The door end 105 of the container 100 may include a door plate, and the door plate may be arranged between two corner posts along the second direction. If it is necessary to spray a logo on the end plate of the front end 104 of the container 100, the spraying device 202 may also be arranged inside the spraying room 201 and in front of the container 100. The spray gun 205 can move along the height direction and the second direction of the container 100. In the figure, the second direction of the container 100 is the Y-axis direction. The logo mold fixing device 206 can abut the logo mold 300 against the front end 104 of the container 100, and the spray gun 205 can spray paint towards the logo mold 300 to form a logo on the front end 104 of the container 100. This is easily achievable by those skilled in the art with simple adjustments based on this embodiment. Of course, if necessary and / or desired, the automatic container logo spraying system 200 according to this application can also be used to spray logos on the door end 105 of the container 100 after simple adjustments.

In a specific embodiment, the positioning device 262 can have two connecting holes arranged in opposite directions along the second direction for respectively receiving and connecting the front end of the piston rod of the driving cylinder 261 and the connecting pin.

[0139] Before spraying, the piston rod of the driving cylinder 261 extends, and the positioning device 262 can drive the identification mold frame 300 to move, abut the identification mold frame 300 against the side plate 102 of the container 100, and maintain a pressing state. After spraying is completed, the piston rod of the driving cylinder 261 retracts, and the positioning device 262 can drive the identification mold frame 300 to move away from the side plate 102 of the container 100.

[0140] In one embodiment, as Figure 2 , Figure 3 , Figure 4 shown, the identification mold frame fixing device 206 further includes:

[0141] A fourth guide rail 265, which is arranged on the second support 266 and is arranged along the first direction of the container 100; the fourth guide rail 265 can be an I-shaped guide rail;

[0142] A first moving seat 263, which is arranged at the tail end of the driving cylinder 261, and the first moving seat 263 is U-shaped;

[0143] At least two fourth pulleys 264, which are arranged inside the first moving seat 263 and are distributed on the upper and lower sides of the fourth guide rail 265. The fourth pulleys 264 are connected to the fourth guide rail 265 and can move along the fourth guide rail 265, so as to support the first moving seat 263 and the driving cylinder 261 to move along the fourth guide rail 265.

[0144] By arranging the first moving seat 263 and the fourth pulleys 264, it is possible to keep the axial direction of the driving cylinder 261 arranged along the Y-axis direction, avoid tilting when the driving cylinder 261 moves, ensure the accurate movement of the identification mold frame 300, and be able to accurately move the identification mold frame 300 to the position where the container 100 needs to be sprayed with identification.

[0145] In one embodiment, as Figure 2 , Figure 5 shown, the identification mold frame fixing device 206 includes at least two fourth guide rails 265, four groups of driving cylinders 261 and four groups of positioning devices 262. The two fourth guide rails 265 are distributed at different heights, and two groups of driving cylinders 261 and two groups of positioning devices 262 are arranged on each fourth guide rail 265. The distance between the two groups of driving cylinders 261 and the two groups of positioning devices 262 on the same fourth guide rail 265 can be adjusted according to the size and shape of the identification. Thereby, the fixing of identification mold frames of different sizes is ensured.

[0146] In some embodiments, the positions of the positioning device 262, the driving cylinder 261, and the fourth guide rail 265 correspond to the positions of the connecting members connected to the identification mold frame 300, so as to achieve reliable connection.

[0147] Understandably, for identification signs of different sizes and / or at different positions, the sizes of the corresponding identification mold bases 300 may also be different, but the relative positions between the connecting members connected to the identification mold bases 300 of different sizes can remain unchanged.

[0148] Each identification mold base 300 is connected to four groups of positioning devices 262, and the identification mold base 300 can obtain stable support. When the size of the identification mold base 300 is relatively large, the distance between the two groups of driving cylinders 261 and the two groups of positioning devices 262 provided on each fourth guide rail 265 can be increased. When the size of the identification mold base 300 is relatively small, the distance between the two groups of driving cylinders 261 and the two groups of positioning devices 262 provided on each fourth guide rail 265 can be reduced. The operations of increasing and reducing the distance can be adjusted by the operator when connecting the identification mold base 300 to the four groups of positioning devices 262.

[0149] In one embodiment, as Figure 2 、 Figure 4 、 Figure 5 shown, the automatic container identification spraying system 200 further includes:

[0150] A mobile support device 207, which extends into the spraying chamber 201 and can support the movement of the container 100 between the outside and inside of the spraying chamber 201. The mobile support device 207 may or may not be provided with a driving device. The mobile support device 207 provided with a driving device can move by itself, and the mobile support device 207 without a driving device needs to be towed for movement.

[0151] Before spraying, the container 100 is placed on the mobile support device 207. The mobile support device 207 moves the container 100 from the outside of the spraying chamber 201 to the inside, and stops at the position of the spraying station for identification spraying operation. After spraying is completed, the mobile support device 207 moves the container 100 from the inside of the spraying chamber 201 to the outside.

[0152] In one embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, the mobile support device 207 includes:

[0153] A fifth guide rail 273, which extends from the outside of the spraying chamber 201 to the inside and is arranged along the first direction of the container 100; the fifth guide rail 273 can be arranged on the ground, and the fifth guide rail 273 can be an I-shaped guide rail;

[0154] The fifth pulley 272 is arranged on the fifth guide rail 273 and can move along the fifth guide rail 273; a groove is arranged on the outer circumferential surface of the fifth pulley 272, and the top of the fifth guide rail 273 can enter the groove, so that the fifth pulley 272 rides on the top of the fifth guide rail 273 and will not easily deviate;

[0155] The second moving seat 271 is supported on the fifth pulley 272, and the top of the second moving seat 271 can support the container 100, specifically, it can support the chassis 103 of the container 100.

[0156] The fifth pulley 272 is provided with an axle, and the second moving seat 271 is supported on the axle. While the second moving seat 271 obtains support, it does not affect the rotation of the fifth pulley 272.

[0157] In actual spraying operations, the fifth pulley 272 can be similar to the box wheels in the prior art or be set as the box wheels in the prior art, and the fifth pulley 272 can be correspondingly connected to the bottom corner fittings of the container 100. It can be understood that the mobile support device 207 can have four fifth pulleys 272. Two of the fifth pulleys 272 are close to the front end 104, and the other two fifth pulleys 272 are close to the door end 105.

[0158] In one embodiment, as Figure 2 、 Figure 5 、 Figure 6 shown, the automatic container identification spraying system 200 further includes:

[0159] Two groups of limiting devices are arranged at both ends of the spraying station inside the spraying room 201, and can limit the container 100 moving to the spraying station, and can keep the container 100 in an accurate position, which is beneficial to carry out the identification spraying operation according to the predetermined design plan, and the identification will also be formed at the designed position on the container 100.

[0160] The limiting device can include a base, a retaining arm and a driving cylinder. The base is arranged on the ground inside the spraying room 201. The retaining arm is arranged on the base and can rotate or move on the base. The driving cylinder is arranged on the base, and the piston rod of the driving cylinder is connected to the retaining arm and can drive the retaining arm to rotate or move to block the mobile support device 207.

[0161] In the illustrated embodiment, the two sets of limiting devices are respectively the first limiting device 208 and the second limiting device 209 in the figure, which respectively correspond to both ends of the labeling station to position the container 100 at the labeling station. The distance between the first limiting device 208 and the second limiting device 209 along the first direction is approximately equal to the length of the container 100. For the convenience of description, both ends of the above-mentioned labeling station are respectively referred to as the "first end" and the "second end", and the direction from the "second end" to the "first end" is parallel to the direction in which the container 100 enters from the entrance of the spraying chamber 201 and moves to the labeling station along the first direction.

[0162] Reference Figure 5 , the first limiting device 208 and the second limiting device 209 can be approximately located at diagonal positions, which is beneficial to stably limit the container 100.

[0163] Figure 5 In the illustrated embodiment, the container 100 enters from the entrance of the spraying chamber 201 and moves to the labeling station with the door end 105 facing forward and the front end 104 facing backward. In some embodiments not shown, the container 100 can also enter from the entrance of the spraying chamber 201 and move to the labeling station with the front end 104 facing forward and the door end 105 facing backward.

[0164] In one embodiment, as Figure 2 , Figure 5 shown, the first limiting device 208 includes:

[0165] A first base 282, the first base 282 is disposed on the inner floor of the spraying chamber 201;

[0166] A first blocking arm 283, the first blocking arm 283 is disposed on the first base 282 and can move on the first base 282 and can maintain linear movement;

[0167] A first driving cylinder 281, the first driving cylinder 281 is disposed on the first base 282, the piston rod of the first driving cylinder 281 is connected to the first blocking arm 283, and can drive the first blocking arm 283 to move to abut against the moving support device 207, thereby blocking the moving support device 207, and further limiting the container 100. Specifically, the piston rod of the first driving cylinder 281 extends along the second direction to drive the first blocking arm 283 to move along the second direction and abut against the fifth pulley 272 of the moving support device 207 along the first direction, thereby limiting the container 100. It can be understood that in this application, the first blocking arm 283 is abutted against the moving support device 207 for limiting, rather than against the container 100 itself, which can avoid damage such as scratches and knocks on the surface of the container 100.

[0168] In one embodiment, as Figure 5 , Figure 6As shown, the second limiting device 209 includes:

[0169] A second base 292, which is arranged on the inner floor of the spraying room 201;

[0170] A second blocking arm 293, which is arranged on the second base 292 and can rotate on the second base 292 by an appropriate angle;

[0171] A second driving cylinder 291, which is arranged on the second base 292. The piston rod of the second driving cylinder 291 is connected to the second blocking arm 293 and can drive the second blocking arm 293 to rotate to abut against the moving support device 207, thereby blocking the moving support device 207 and further limiting the container 100. Specifically, the piston rod of the first driving cylinder 291 moves along the second direction to drive the second blocking arm 293 to rotate along the first direction and abut against the fifth pulley 272 of the moving support device 207 along the first direction, thereby limiting the container 100. It can be understood that in this application, the second blocking arm 293 is abutted against the moving support device 207 for limiting, rather than against the container 100 itself, which can avoid damage such as scratches and knocks on the surface of the container 100.

[0172] In some embodiments, the piston rod of the first driving cylinder 291 can convert the linear motion of the piston rod into rotational motion via, for example, a lever mechanism, a crank-slider mechanism, etc., so as to drive the second blocking arm 293 to rotate along the first direction. The above lever mechanism can be similar to Figure 5 the structure in the second limiting device 209.

[0173] Refer to Figure 5 , before spraying, the container 100 enters the spraying room from the entrance of the spraying room 201 and moves along the first direction towards the labeling station. The piston rod of the first driving cylinder 281 extends along the second direction, driving the first blocking arm 283 to move along the second direction to block the moving support device 207 from further moving along the first direction. Specifically, the first blocking arm 283 abuts against the fifth pulley 272 close to the door end 105 along the first direction. After the piston rod of the first driving cylinder 281 acts, and after the fifth pulley 272 close to the front end 104 passes along the first direction through the second driving cylinder 291, the piston rod of the second driving cylinder 291 moves along the second direction to drive the second blocking arm 293 to rotate along the first direction and abut against the fifth pulley 272 close to the front end 104 along the first direction, thereby limiting the container 100.

[0174] Therefore, the first limiting device 208 and the second limiting device 209 respectively abut against the fifth pulley 272 close to the door end 105 and the fifth pulley 272 close to the front end 104 at both ends of the spraying station inside the spraying room 201, thereby limiting the container 100 and positioning the container 100 at the spraying station inside the spraying room 201.

[0175] After spraying is completed, the piston rod of the first driving cylinder 281 retracts, driving the first blocking arm 283 to disengage from the fifth pulley 272 of the mobile support device 207, and the piston rod of the second driving cylinder 291 retracts, driving the second blocking arm 293 to disengage from the fifth pulley 272 of the mobile support device 207, thereby releasing the limit on the container 100.

[0176] In one embodiment, if Figure 2 , Figure 5 As shown, four groups of spray devices 202 and two groups of identification mold frame fixing devices 206 are symmetrically arranged on both sides of the interior of the spray room 201. The four groups of spray devices 202 and the two groups of identification mold frame fixing devices 206 are respectively located on both sides of the second direction of the container 100. The identification spraying operation can be performed on both sides of the container 100 at the same time to improve the operation efficiency.

[0177] The two sets of spraying devices 202 on the same side of the container 100 can be linked or can be moved individually. When the marking area is large, two sets of spraying devices 202 (using two spray guns 205) can be used to spray on the same side of the container 100 at the same time. When the marking area is small, one set of spraying devices 202 (using one spray gun 205) can be used to spray on the same side of the container 100.

[0178] According to an automatic container marking spraying system of the present application, by providing a spray gun that can move along the height direction and the first direction of the container, and a marking mold frame fixing device, it is possible to automatically spray the marking on the side panel of the container, instead of manual spraying, meet the needs of spraying markings of various box types, meet the needs of spraying markings of different sizes and shapes, improve the spraying efficiency, ensure the spraying quality, eliminate the quality risks caused by large personnel turnover and unstable skills, and effectively reduce production costs.
