Description

Technical Field

[0001] The invention relates to the technical field of ceramic fragile product packaging, and in particular to an instant outer packaging device for ceramic fragile products and a use method thereof. Background Art

[0002] China's ceramic culture has a long history, and now it is exported overseas and has a huge trading market. The characteristics of ceramic fragile products, such as being afraid of falling and being easily broken, not only restrict the development of the ceramic fragile products market, but also put forward higher requirements for the packaging and transportation industry. According to the information, the main form of damage to ceramic fragile products is mechanical damage during transportation, with a damage rate of up to 90%.

[0003] The existing packaging of fragile ceramics mainly adopts traditional packaging technology, corrugated paper box packaging technology and air bag packaging. Among them, the traditional packaging technology is mainly for low-priced household fragile ceramics and large ornamental fragile ceramics, such as Figure 1 As shown in the figure, the method of winding straw ropes and nailing wooden frames to ensure the safety of transportation is adopted. Although the packaging process is simple, the cost is low, and the packaging materials will not cause pollution to the environment, the protection effect is not ideal, the damage rate is high, and the work efficiency is low, which is time-consuming and labor-intensive; Figure 2 As shown in the figure, the corrugated box packaging process is to put the ceramic fragile products into the corrugated box, and then fill it with newspapers or foam and other cushioning materials to resist collision and impact. Although the material is easy to obtain, the process is simple, and there is no technical requirement, the protection effect is poor and it is not suitable for long-distance transportation. In addition, the foam will cause environmental pollution and is difficult to clean; Figure 3 As shown in the figure, the air bag packaging uses airbag-type plastic bags for cushioning protection. Although it saves space and reduces the overall weight after packaging, the air bag packaging has certain requirements on the appearance of the product. If the product has a complex or irregular shape, it is difficult to form effective protection. Moreover, this type of packaging cannot resist high temperature environments and punctures from sharp objects. In addition, Figure 4As shown, the existing foaming device packaging system works by placing ceramic fragile products in a carton, and then pouring a foaming agent into the carton. The foaming agent is used to fill the carton with the foaming agent through its expansion, thereby protecting the ceramic fragile products in all directions. During use, it has four obvious defects. First, it is necessary to take certain protective measures for the carton. Before spraying the foaming agent, a PE plastic film should be laid inside the carton to protect the carton. Second, because the foaming agent requires a certain solidification time, during which the carton is closed, the posture of the ceramic fragile products in the carton is uncontrollable, and it is possible that the ceramic fragile products will lean to one side, resulting in uneven protection. This increases the risk during transportation. Third, the excellent performance of the polyurethane foaming agent makes it widely used in the packaging industry. In order to save materials, the consumption of each packaging should be minimized. However, because the foaming agent needs to fill the entire carton, the unit consumption of this system is large, resulting in an increase in total consumption. Fourth, the machine is manually operated, and the operator needs to judge the amount of foaming agent sprayed by himself. It has not achieved automation and intelligence, which is inconsistent with the current development concept.

[0004] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Summary of the invention

[0061] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] Embodiment 1:

[0063] Embodiment 1 of the present invention provides a ceramic fragile product instant outer packaging device, such as Figure 5-6 As shown, it includes a rotating module 1, a spray gun module 2, an infrared ranging sensor 3 and a frame 4;

[0064] The rotating module 1 includes a rotating chassis 11, which is horizontally rotatably arranged in the frame 4 and is used to drive the ceramic fragile product 5 to rotate;

[0065] The infrared distance measuring sensor 3 is arranged on the frame 4 in the vertical direction, and is used to measure the shape of the ceramic fragile product 5;

[0066] The spray gun module 2 includes a spray gun 21 and an ultrasonic sensor 22, wherein the ultrasonic sensor 22 is used to monitor the distance between the nozzle of the spray gun 21 and the surface of the ceramic fragile product 5; the spray gun 21 is arranged in the frame 4 and can be moved in the front-back and up-down directions to spray the packaging material;

[0067] The spray gun module 2 is used to control the movement trajectory of the spray gun 21 according to the shape of the ceramic fragile product 5, so as to facilitate the packaging of the ceramic fragile product 5.

[0068] The rotating module 1 of the present invention is provided with a rotating chassis 11, and the ceramic fragile product 5 is arranged at the center of the rotating chassis 11. The rotating chassis 11 rotates, driving the ceramic fragile product 5 to rotate, and the shape of the ceramic fragile product 5 is measured by the infrared distance sensor 3 provided, and the spray gun module 2 is adjusted, and the ultrasonic sensor 22 is used for positioning, so that the distance between the nozzle of the spray gun 21 and the surface of the ceramic fragile product 5 is equal to the set value; during the rotation of the ceramic fragile product 5, the spray gun 21 sprays the packaging material to facilitate the packaging of the ceramic fragile product 5. The present invention measures the shape of the ceramic fragile product 5 by the infrared distance sensor 3, and sets the corresponding packaging strategy according to the shape of the ceramic fragile product 5 to save the packaging material for packaging the ceramic fragile product 5. For the embodiment of the present invention, the packaging of the embodiment of the present invention can be but not limited to using polyurethane foam material; in addition, the first preset distance from the spray gun 21 to the surface of the general fragile product in the embodiment of the present invention is jointly determined according to the shape of the ceramic fragile product 5 and the actual thickness required to be sprayed. The present invention preferably sets the ceramic fragile product 5 at the center of the rotating chassis 11, and the plane formed by the movement of the spray gun 21 passes through the center of the rotating chassis 11, so that the spray gun 21 can more conveniently spray packaging materials on the ceramic fragile product 5. In order to obtain the complete appearance of the ceramic fragile product 5, the embodiment of the present invention generally sets a plurality of infrared ranging sensors 3 to form an infrared ranging detection array. The number of infrared ranging sensors 3 in the embodiment of the present invention is determined by the height of the ceramic fragile product 5 and the height measured by each infrared ranging sensor 3. It is worth noting that the present invention is not only applicable to the packaging of ceramic fragile products, but also to the packaging of other products (for example, metal products, wooden products, glass products, etc.).

[0069] Based on the shape of the ceramic fragile product 5 measured by the infrared ranging sensor 3 of the embodiment of the present invention, the embodiment of the present invention also provides three feasible packaging strategies, which can also be called packaging modes, including: cylindrical packaging mode (mode 1), rectangular packaging mode (mode 2) and ceramic fragile product 5 prototype packaging mode (mode 3). The packaging equipment of the present invention packages the ceramic fragile product 5 into a cylinder, the interior of the cylinder completely fits the ceramic fragile product 5, the height is equal to the ceramic fragile product 5, and the diameter is the maximum outer diameter of the ceramic fragile product 5 plus twice the thickness set by the user. Figure 7a-7b As shown, when the infrared ranging sensor 3 determines that the ceramic fragile products 5 are packaged using mode 1, the specific working method is as follows: the spray gun 21 moves horizontally according to the data collected by the scanning device. When the nozzle of the spray gun 21 is a preset distance (for example, 10 mm) away from the surface of the ceramic fragile products 5, the rotating platform starts to work, driving the ceramic fragile products 5 to rotate. At the same time, the spray gun 21 switch is turned on, so that the foaming agent begins to spray out evenly. After the platform rotates one circle, the spray gun 21 retreats a preset distance, and then continues to execute the previous process until the set packaging thickness is reached. The packaging equipment is reset, and the bottom layer of the ceramic fragile products 5 is packaged. After that, the spray gun 21 rises a preset distance in the vertical direction, and then packages layer by layer in the same process, and stops after reaching the specified packaging height. For irregular ceramic fragile products 5 that are non-coaxial rotating bodies, when the spray gun 21 reaches the irregular part, it will automatically retreat to avoid it, and after the irregular part is rotated, the spray gun 21 will automatically advance to the previous position [2]; wherein, in Figure 7b In the figure, the dotted line s0 is the final outline of the package; the thick black solid line is the outline of the porcelain; the thin black solid line s1 is the movement trajectory of the foaming agent spraying gun head; the dotted line s2 is the movement trajectory of the non-foaming agent spraying gun head; and the arrow a is the rotation direction of the porcelain.

[0070] like Figure 8a-8b As shown, mode 2 is processed on the basis of mode 1. First, according to the working principle of mode 1, the porcelain is packaged into a cylinder with a certain outer diameter, and then the cylinder is supplemented into a rectangle with a side length equal to the sum of the maximum outer diameter of the porcelain and twice the thickness set by the user. When the embodiment of the present invention performs mode 2 packaging, when the cylinder is packaged into a rectangle, it is impossible to spray the packaging continuously in a full circle (because in the process of packaging the cylinder into a rectangle, some parts of the cylinder require thin spraying, and some parts require late spraying, especially the top corners require the thickest spraying thickness). Therefore, when the cylinder is sprayed into a rectangle, the present invention decomposes the rectangle into small rectangular areas with four corners, and sprays each area reciprocatingly, one by one, until the four small rectangular areas are sprayed in sequence [3]. Figure 8b As shown, the thick black solid line is the outline of the porcelain; the thin solid line s3 is the outline of the cylindrical packaging in mode 1; s4 is the movement trajectory of the foaming agent gun head; s5 is the final outline of mode 2; and the arrows ab are the rotation direction of the porcelain (reciprocating rotation).

[0071] Mode 3 covers a certain thickness of foaming agent according to the original shape of the porcelain. The working principle is the same as that of mode 1, but the packaging thickness of each layer is slightly different. The shape after packaging is consistent with the porcelain. Compared with other modes, this mode has the characteristics of good anti-fall effect, material saving and high packaging efficiency for packaging of certain regular-shaped (such as cylindrical) porcelain. The present invention measures the shape of the ceramic fragile product 5 through the infrared ranging sensor 3, and selects a suitable packaging mode according to the shape of the ceramic fragile product 5, which can effectively save the packaging materials for packaging the ceramic fragile product 5.

[0072] In order to illustrate the complete solution of the present invention, the specific details of the present invention are explained in detail below. In order to realize the forward and backward movement of the spray gun 21, the same layer of the ceramic fragile products 5 is packaged, such as Fig. 9 As shown, the spray gun module 2 described in the embodiment of the present invention also includes a first moving component 23 and a first support plate 24; the first moving component 23 includes a first motor 231, a first screw guide 232, a first screw guide nut 233 and a parallel guide 234; the first screw guide 232 is arranged in the direction of the spray gun 21 moving forward and backward, the output shaft of the first motor 231 is connected to one end of the first screw guide 232, the parallel guide 234 is arranged on the projection of the first screw guide 232 on the first support plate 24 in the vertical direction, the spray gun 21 is arranged on the first screw guide nut 233, the first screw guide nut 233 can be arranged on the parallel guide 234 moving forward and backward, the first screw guide nut 233 is sleeved on the first screw guide 232, and the first motor 231 rotates to drive the spray gun 21 to move forward and backward.

[0073] The first moving component 23 of the embodiment of the present invention is provided with a first motor 231, and the output shaft of the first motor 231 is connected to one end of the first screw guide rail 232. The rotation of the first motor 231 drives the first screw guide rail 232 to rotate synchronously, and the first screw guide rail nut 233 is sleeved on the first screw guide rail 232 to form a screw-nut structure; the surface of the first screw guide rail 232 is provided with an external thread, and the inner surface of the first screw guide rail nut 233 is provided with an internal thread, and the internal thread and the external thread match each other.

[0074] The first moving assembly 23 of the embodiment of the present invention can only realize the packaging of the ceramic fragile products 5 in the same layer. In order to package the ceramic fragile surface as a whole, such as Fig.10aAs shown, the spray gun module 2 of the embodiment of the present invention further includes a second moving assembly 25; the second moving assembly 25 includes a second motor 251, a second lead screw guide 252 and a second lead screw guide nut 253; the second lead screw guide 252 is arranged in the direction of the spray gun 21 moving up and down, the output shaft of the second motor 251 is connected to one end of the second lead screw guide 252, the second lead screw guide nut 253 is sleeved on the second lead screw guide 252, and the side wall of the second lead screw guide nut 253 is connected to the first support plate 24; the first moving assembly 23 is arranged on the first support plate 24, and the second motor 251 drives the second lead screw guide nut 253 and the first support plate 24 to move up and down, so as to drive the spray gun 21 to move up and down. When the next layer of the ceramic fragile product 5 is packaged, the spray gun 21 is moved upward by a preset distance, and the spray gun 21 sprays the packaging material to package the upper layer of the ceramic fragile product 5, and adopts a layer-by-layer packaging method until the ceramic fragile product 5 is packaged from bottom to top. In addition, in order to enable the spray gun to move smoothly to the preset position, the second moving assembly 25 of the embodiment of the present invention also has a preferred setting mode, such as Fig.10b In the present invention, an auxiliary slide bar and a nut (not marked in the figure, but can be easily seen from the figure) are provided on the basis of the original second moving component 25. The slide bar and the nut are smoothly arranged, and the slide rail is arranged in parallel with the second lead screw guide rail 252.

The output shaft of the third motor 13 is connected to the center of the rotating chassis 11. The third motor 13 rotates, driving the rotating chassis 11 and the ceramic fragile product 5 to rotate coaxially. In addition, the spray gun 21 sprays the packaging material, so that the ceramic fragile product 5 generates a lateral force. During the rotation of the ceramic fragile product 5, it is very easy to tip over, thereby causing the ceramic fragile product 5 to break. In the actual production process, in order to avoid the problem of the ceramic fragile product 5 falling due to uneven force, the embodiment of the present invention usually sets a suction cup at the position where the ceramic fragile product 5 is placed at the center of the rotating chassis 11. Through the setting of the suction cup, the ceramic fragile product 5 can be stably fixed by the suction cup at the center of the rotating chassis 11.

[0078] When packaging the surface of ceramic fragile products 5, in order to improve the convenience of adding materials, such as Figure 6 As shown, the spray gun 21 described in the embodiment of the present invention is provided with an opening 211 for connecting an external feeding pipe. The packaging material is transported into the spray gun 21 through the external feeding pipe, and the ceramic fragile products 5 are packaged through the spray gun 21.

[0079] In order to more accurately control the amount of packaging material sprayed by the spray gun 21 per unit time (i.e., the speed at which the spray gun 21 sprays the packaging material), a proportional integral valve 6 is provided at the connection between the feed port of the feed pipe and the opening 211 in the embodiment of the present invention, and a flow sensor is provided in the spray gun 21; the flow sensor is used to monitor the spray speed of the packaging material in the spray gun 21; the proportional integral valve 6 is used to adjust the size of the feed port of the feed pipe to adjust the feeding speed of the feed pipe.

[0080] like Fig.12 As shown, it is a working principle diagram of the proportional integral valve 6. The proportional integral valve 6 adjusts the effective area of ​​the feed port to achieve control of the feed amount of the packaging material in the spray gun 21. A flow sensor is set in the feed pipe, and the flow signal detected by the flow sensor is obtained through the corresponding control circuit. Then, the opening 211 of the proportional integral valve 6 is adjusted, thereby achieving the purpose of accurately controlling the speed of the spray gun 21 spraying out the packaging material.

[0081] After the ceramic fragile product 5 is packaged, the packaging material on the ceramic fragile surface needs to be cured. The packaging material generally used in the embodiment of the present invention is a polyurethane foam material, such as Fig.13a The figure shows the relationship between the curing rate and temperature of polyurethane foaming materials. The main environmental factor affecting the performance of polyurethane foaming agents in packaging is air temperature. In order to improve production efficiency, the shorter the curing time, the better. Fig.13bAs shown, the present invention further includes a temperature control module 7, which includes a heater and a temperature sensor (the heater and the temperature sensor can be integrated together to form a temperature control module 7, or can be separately set. In 13b, an integrated method is adopted, so the heater and the temperature sensor are not marked); the temperature sensor is used to detect the ambient temperature of the ceramic fragile product 5; the heater is arranged on the rack 4 and aligned with the ceramic fragile product 5 to ensure that the surface of the ceramic fragile product 5 ensures the curing temperature of the material. From Figure 13, it can be concluded that 38 to 42°C is the optimal solidification temperature range of the polyurethane foaming agent. The value obtained by collecting the ambient temperature using the temperature sensor is used as input, and the heat emitted by the heater, such as a heating bulb, is used as output to build a closed-loop temperature control system so that the working environment of the porcelain is always at 38 to 42°C. In addition, according to actual needs, a refrigerator can also be set in the embodiment of the present invention. When the surface packaging material of the ceramic fragile product 5 needs to be cured, the packaging material on the surface of the ceramic fragile product 5 is maintained within the optimal curing temperature range through the joint action of the refrigerator and the heater.

[0082] In order to realize automation, the embodiment of the present invention is also provided with a safety alarm system, which mainly includes a limit switch, a flow valve and an ultrasonic distance sensor as input elements, and a buzzer as an output element. Fig.14 As shown, in order to prevent some extreme working conditions from happening and protect the safety of users and machines, we have set up safety alarms in the following three aspects. When the foaming agent is about to run out, the flow rate will change to a certain extent. We will set up monitoring of the flow threshold in the program. When the collected value reaches the preset threshold, the machine will trigger the buzzer alarm system and stop the machine, waiting for the user to replenish the foaming agent, and then the machine will continue to work after the user presses the run button. When the program is confused and causes the spray gun 21 to move excessively, it will cause damage to the machine or porcelain. For this reason, we have installed a limit switch at the edge of the maximum movement range of the machine. When the program detects a normally closed signal from the limit switch, the machine will also trigger the alarm system and automatically return to a safe position. The program specifies the safe range of the input component data signal, and constantly monitors the remaining amount of foaming agent and the moving distance of the spray gun 21 to ensure the safety of users and machines.

[0083] The rotating module 1 of the present invention is provided with a rotating chassis 11, and the ceramic fragile product 5 is arranged at the center of the rotating chassis 11. The rotating chassis 11 rotates, driving the ceramic fragile product 5 to rotate, and the shape of the ceramic fragile product 5 is measured by the infrared distance sensor 3 provided, and the spray gun module 2 is adjusted, and the ultrasonic sensor 22 is used for positioning, so that the distance between the nozzle of the spray gun 21 and the surface of the ceramic fragile product 5 is equal to the set value; during the rotation of the ceramic fragile product 5, the spray gun 21 spits out packaging materials to facilitate the packaging of the ceramic fragile product 5. The present invention measures the shape of the ceramic fragile product 5 by the infrared distance sensor 3, and sets the corresponding packaging strategy according to the shape of the ceramic fragile product 5 to save the packaging materials for packaging the ceramic fragile product 5; at the same time, the packaging equipment of the present invention is used to package the ceramic fragile product 5 in real time, which reduces the setting of the carton, and in terms of the degree of mobility, it can avoid the damage caused to the ceramic fragile product 5 due to uneven protection. The embodiment of the present invention sets a flow meter in the spray gun 21 and sets a proportional integral valve 6 at the feed port of the spray gun 21. The flow meter measures the rate at which the nozzle sprays the packaging material, and then adjusts the effective area of ​​the feed port through the proportional integral component, thereby achieving precise control of the nozzle inlet and outlet. In addition, the present invention also sets a temperature control module 7. Through the replenishment of the temperature control module 7, the packaging material on the surface of the ceramic fragile product 5 can be quickly solidified, thereby achieving instant packaging of the ceramic fragile product 5.

[0084] Embodiment 2:

[0085] Compared with the instant outer packaging equipment for ceramic fragile products in Example 1 of the present invention, Example 2 of the present invention further proposes a method for using the instant outer packaging equipment for ceramic fragile products, which specifically includes: the rotating module 1 drives the ceramic fragile products 5 to rotate, detects the shape of the ceramic fragile products 5 through the infrared ranging sensor 3, and extracts the maximum height and maximum outer diameter of the ceramic fragile products 5; sets the spraying mode of the spray gun 21 according to the shape of the ceramic fragile products 5, drives the spray gun 21 to move to the first preset position, and the spray gun 21 sprays packaging material to perform ring packaging on the ceramic fragile products 5; drives the spray gun 21 to move upward to the second preset position, and the spray gun 21 sprays packaging material to continue to perform ring packaging on the ceramic fragile products 5 until the surface of the ceramic fragile products 5 is sprayed with packaging material from bottom to top.

[0086] See also Fig.15 As shown, the method of use includes:

[0087] Step 201 : the third motor 13 drives the ceramic fragile object 5 to rotate, the infrared distance sensor 3 detects the shape of the ceramic fragile object 5 , and extracts the maximum height and maximum outer diameter of the ceramic fragile object 5 .

[0088] The present invention first scans with the infrared distance measuring sensor 3 to obtain the shape data of the ceramic fragile product 5. Then, a corresponding spraying mode and spraying thickness are formulated according to the shape data of the ceramic fragile product 5.

[0089] Step 202: The spraying mode of the spray gun 21 is set according to the shape of the ceramic fragile product 5. The first motor 231 and the second motor 251 drive the spray gun 21 to move to the first preset position. The spray gun 21 sprays packaging material to perform annular packaging on the ceramic fragile product 5.

[0090] Among them, after selecting the spraying mode and spraying thickness according to the shape data of the ceramic fragile product 5, the first motor 231 drives the spray gun 21 to move forward and backward, and the second motor 251 drives the spray gun 21 to move up and down to the first preset position; after moving to the first preset position, the spray gun 21 stops moving. The third motor 13 continues to rotate, and the spray gun 21 sprays the packaging material. Under the action of the third motor 13, the ceramic fragile product 5 is annularly packaged. The first preset position of the embodiment of the present invention is determined according to the shape of the ceramic fragile product 5 and the thickness of the spray on the surface of the ceramic fragile product 5.

[0091] Step 203: The first motor 231 and the second motor 251 drive the spray gun 21 to move upward to the second preset position, and the spray gun 21 sprays the packaging material to continue to perform annular packaging on the ceramic fragile products 5 until the packaging material is sprayed from the bottom to the top of the surface of the ceramic fragile products 5.

[0092] Among them, when the layer at the first preset position is completed by spraying and packaging, the spray gun 21 returns to its original position, the second motor 251 moves upward, and the spray gun 21 moves back and forth to a preset distance from the surface of the ceramic fragile product 5. The preset distance here is equal to the thick bottom of the ceramic fragile product 5 that needs to be sprayed, and then the ceramic fragile product 5 continues to be packaged in a ring until the surface of the ceramic fragile product 5 is completely packaged.

[0093] In addition, in order to speed up the curing rate of the packaging material on the surface of the ceramic fragile product 5, after the packaging material is sprayed from the bottom to the top on the surface of the ceramic fragile product 5 as described in the embodiment of the present invention, it also includes using the temperature control module 7 to cure the packaging material on the surface of the ceramic fragile product 5, specifically including: setting the temperature range for curing the packaging material according to the performance of the packaging material; using a temperature sensor to measure the ambient temperature of the ceramic fragile product 5, and compensating the ambient temperature through a heater, so that the packaging material on the surface of the ceramic fragile product 5 is within the set curing temperature range.
