Description

Technical Field

[0001] The invention relates to the technical field of hot pot base material processing, in particular to a demoulding machine and a demoulding method thereof. Background Art

[0002] The existing block-shaped hot pot soup base needs to be separated from the box body after being taken out from the freezer, so as to facilitate the subsequent packaging of the hot pot soup base into a packaging bag for packaging.

[0003] Conventional separation of hot pot soup base and box body is completed by manual operation, but due to the direct participation of manual labor in the whole separation process, the labor intensity is large and the production efficiency is low, and it is difficult to ensure that manual labor will not pollute the hot pot soup base. In addition, there is also a technology that relies on the heating method to separate the hot pot soup base and the box body, such as the demoulding production line disclosed in the patent documentation of publication number CN111439562A, which heats the surface of the hot pot soup base to melt so that it is separated from the box body. However, the use of the heating method to separate the hot pot soup base from the box body requires accurate control of the heating temperature and the heating area, otherwise the hot pot soup base will be melted over a large area, so the actual operation difficulty is relatively large.

[0040] Example

[0041] Please refer to Figure 1The present invention provides a demoulding machine for automatically separating a box body 100 of boxed materials and solidified materials in the box body 100. The solidified materials in this embodiment are frozen hot pot soup base. The demoulding machine comprises a first conveying mechanism 1, a separation mechanism 2, a turning mechanism 3, a second conveying mechanism 4, a pushing mechanism 5 and a demoulding mechanism 6 which are sequentially arranged along the conveying direction of the boxed materials.

[0042] The first conveying mechanism 1 may be, but is not limited to, a conventional belt conveyor, and the first conveying mechanism 1 is used to convey the boxed materials with the opening facing upward to the separation mechanism 2 for separation.

[0043] The separation mechanism 2 is used to separate the inner wall of the box body 100 from the outer wall of the solidified material, and to convey the separated boxed material to the turning mechanism 3. It should be noted that the boxed material separated by the separation mechanism 2 is still an integral structure because the bottom of the box body 100 and the bottom of the hot pot base are still adhered together. Compared with the separation of the box body 100 and the hot pot base by heating, the surface of the hot pot base does not need to be melted or softened, the operation difficulty is low, and the quality of the hot pot base can be prevented from being affected.

[0044] For details, please refer to Figure 2 and Figure 3 The separation mechanism 2 includes a separation bracket 201 and a separation unit. The separation unit includes a separation drive device I202, a separation drive device II203, a pair of separation plates 204, and a separation conveyor belt 205 for receiving the boxed materials conveyed by the first conveying mechanism 1. The two separation plates 204 are arranged opposite to each other. The separation drive device I203 is installed on the separation bracket 201. The separation drive device I202 is used to drive the two separation plates 204 to move closer to or away from each other. The separation drive device II203 is used to drive the separation drive device I202 to reciprocate in the vertical direction. The separation conveyor belt 205 is located below the separation plate 204 to realize the separate conveying of the boxed materials. At the same time, in order to detect whether there is a boxed material on the separation conveyor belt 205, a material sensing device 206 can be provided on the separation conveyor belt 205 for detection, wherein the material sensing device 206 can be but not limited to an infrared sensing device in the prior art, and the infrared sensing device can detect whether there is a boxed material on the separation conveyor belt 205.

[0045] It should be noted that the separation drive device II 203 of this embodiment can be any linear drive device or other combination mechanism capable of linear reciprocating motion, such as a cylinder, a hydraulic cylinder, an electric push rod, etc., and the present embodiment is preferably a cylinder. The separation drive device II 203 is mounted on the separation bracket 201, the output end of the separation drive device II 203 is connected to the mounting frame 207, and the separation drive device I 202 is mounted on the mounting frame 207, so that when the separation drive device II 203 drives the mounting frame 207 to reciprocate in the vertical direction, the separation drive device I 202 can be driven to reciprocate in the vertical direction, and then the separation drive device I 202 drives the two separation plates 204 to reciprocate in the vertical direction, and at the same time, the separation drive device I 202 can also drive the two separation plates 204 to move closer to or away from each other when it is working.

[0046] Preferably, the separation drive device 1202 of this embodiment is a pneumatic clamp with stable operation process, wherein the two clamping jaws of the pneumatic clamp are both installed with a connecting plate 208 by bolts, the separation plate 204 is connected to the clamping jaw of the pneumatic clamp by the connecting plate 208, and the separation plate 204 and the connecting plate 208 can also be connected by bolts, which is convenient for replacing and removing the separation plate 204. In order to make the structure of the separation plate 204 more stable during the movement, the connecting plate 208 and the separation plate 204 are both L-shaped structures, and one of the side walls of the separation plate 204 extends downward in the vertical direction so that it can extend into the box body 100. When compressed air is introduced into the pneumatic clamp, the two clamping jaws of the pneumatic clamp move away from each other, and at this time, the two clamping jaws drive the two separation plates 204 away from each other with a certain force; conversely, the two clamping jaws of the pneumatic clamp can also drive the two separation plates 204 closer to each other.

[0047] In addition, considering that the actual box body 100 is often a rectangular structure including four side walls, in order to separate the four outer side walls of the hot pot soup base from the four inner side walls of the box body 100 without rotating the boxed material, the number of the above-mentioned separation units is two; the two separation units are arranged in sequence along the transmission direction of the boxed material, and the center line of the two separation plates 204 of one separation unit is perpendicular to the center line of the two separation plates 204 of the other separation unit. That is to say, when the hot pot soup base is actually separated from the box body 100, after the two opposite outer side walls of the hot pot soup base are separated from the inner side wall of the box body 100 by one of the separation units, the box body 100 continues to move forward to the bottom of the other separation unit, so that the other two opposite outer side walls of the hot pot soup base are separated from the inner side wall of the box body 100 by relying on the separation unit, so that all the outer side walls of the hot pot soup base can be separated from all the inner side walls of the box body 100.

[0048] The working principle of the separation mechanism 2 is as follows: when the boxed material moves from the first conveying mechanism 1 to the separation conveyor belt 205 of the first separation unit, the initial spacing between the two separation plates 204 is equal to the width between the inner walls of the box body 100. At this time, the separation drive device I I203 drives the mounting frame 207 to move downward, thereby driving the separation drive device I202 to move downward together with the two separation plates 204, so that the bottom ends of the two separation plates 204 extend into the interior of the box body 100. At this time, the outer wall of each separation plate 204 contacts the inner wall of the box body 100, and the inner wall of the separation plate 204 contacts the outer wall of the hot pot base. Subsequently, the two separation plates 204 are driven away from each other by the separation drive device I202, so that the outer wall of the hot pot base can be separated from the inner wall of the box body 100. After the two outer walls of the hot pot soup base are separated from the two inner walls of the box body 100, the separation conveyor belt 205 of the separation unit transfers the boxed material to the separation conveyor belt 205 of the next separation unit, and the box body 100 and the hot pot soup base are further separated by the next separation unit, so that all the outer walls of the hot pot soup base and all the inner walls of the box body 100 can be separated. It can be seen that this embodiment uses a purely mechanical mechanism to separate the hot pot soup base and the box body 100, and on the basis of reducing the labor intensity, it avoids the problem of contamination of the hot pot soup base caused by human participation in the separation process as much as possible, thereby improving the production quality; at the same time, the whole separation process is simple and fast, and can avoid the disadvantages of separating the box body 100 and the hot pot soup base by heating, which greatly improves the actual production efficiency.

[0049] The turning mechanism 3 is used to turn the boxed materials with the opening facing upward to a state with the opening facing downward, and to convey the boxed materials with the opening facing downward to the second conveying mechanism 4 .

[0050] Please refer to Figure 4 The flip mechanism 3 includes an inner arc side plate 301 and an outer arc side plate 302, and a flip channel 303 for the boxed materials to pass through is formed between the inner arc side plate 301 and the outer arc side plate 302. The boxed materials transmitted from the separation mechanism 2 enter the flip channel 303, and under the action of the inner arc side plate 301 and the outer arc side plate 302, the boxed materials change from the state of opening upward to the state of opening downward. Compared with the prior art, the flip mechanism 3 of this embodiment has a simpler structure, and under the synergistic effect with the above-mentioned separation mechanism 2, there is no need to set a corresponding blocking mechanism, and the cost is also lower.

[0051] The second conveying mechanism 4 can also be, but is not limited to, a conventional belt conveyor, and is used to convey the boxed materials with the opening downward to the pushing mechanism 5, so that the second conveying mechanism 4 plays a certain buffering role, so that the boxed materials enter the pushing mechanism 5 in an orderly manner. Figure 1The second conveying mechanism 4 of this embodiment includes a first horizontal conveying section 401, a second horizontal conveying section 402 and an inclined conveying section 403, wherein one end of the first horizontal conveying section 401 is connected to the discharge port of the flip mechanism 3, and one end of the second horizontal conveying section 402 is vertically connected to the other end of the first horizontal conveying section 401, and one end of the inclined conveying section 403 is vertically connected to the other end of the second horizontal conveying section 402, and the other end of the inclined conveying section 403 is used as the discharge port to convey the boxed materials to the push mechanism 5. Such an arrangement can reduce the length of the second conveying mechanism 4 as much as possible, so that the structure of the entire demoulding machine is more compact and occupies a smaller area.

[0052] The pushing mechanism 5 is used to completely separate the bottom of the box body 100 from the solidified material, and continue to transport the boxed material to the demoulding mechanism 6.

[0053] For details, please refer to Figure 5 and Figure 6 The pushing mechanism 5 includes a pushing bracket 501, a pushing drive device 502, a pushing plate 503 and a pushing conveyor belt 504; the pushing drive device 502 is installed on the pushing bracket 501 and is used to drive the pushing plate 503 to reciprocate in the vertical direction; a vibrator 505 is provided on the top surface of the pushing plate 503, and a vibration block 506 used in conjunction with the vibrator 505 is provided on the bottom surface of the pushing plate 503, and the pushing conveyor belt 504 is located below the vibration block 506. The vibration is transmitted to the vibration block 506 by the vibrator 505, and the bottom of the box body 100 is vibrated by the vibration block 506 to force the hot pot base to separate from the bottom of the box body 100. Preferably, the vibrator 505 of this embodiment adopts an air hammer vibrator with a stable operation process and good vibration effect. By setting the pushing conveyor belt 504, it is possible to realize the separate conveying of boxed materials.

[0054] At the same time, in order to improve the stability of the boxed materials on the push conveyor belt 504, clamping units are provided on both sides of the push conveyor belt 504; the clamping units include a clamping drive device 507 and a clamping plate 508, and the clamping plates 508 of the two clamping units are driven by the respective clamping drive devices 507 to move closer to or farther from each other, so as to clamp the box body 100 through the two clamping plates 508. In addition, in order to enable the boxed materials to be smoothly transferred from the discharge end of the second conveying mechanism 4 to the push conveyor belt 504, the side of the clamping plate 508 away from the demoulding mechanism 6 is expanded and extended outward, so that the two clamping plates 508 are close to the second conveying mechanism 4. The end forms a flared mouth to limit the movement trajectory of the boxed materials.

[0055] It should be noted that the pushing drive device 502 and the clamping drive device 507 of this embodiment can also be any linear drive device or other combined mechanism that can perform linear reciprocating motion, such as a cylinder, a hydraulic cylinder, an electric push rod, etc. The pushing drive device 502 and the clamping drive device 507 of this embodiment are preferably cylinders with stable and efficient operation.

[0056] In addition, the output end of the push driving device 502 is connected to a fixed plate 509, which is located above the push plate 503. A plurality of shock absorbing members are provided between the fixed plate 509 and the push plate 503 to improve the stability of the push plate 503 during movement and when the vibration block 506 vibrates the bottom of the box body 100. Preferably, there are two shock absorbing members in this embodiment, and the two shock absorbing members are symmetrically distributed on both sides of the vibrator 505 along the axis of the vibrator 505 to further improve the vibration reduction effect.

[0057] Specifically, the shock absorbing member includes a guide shaft 5010, a guide sleeve 5011, a fixing seat 5012 and a shock absorbing spring 5013; the guide sleeve 5011 is arranged on the bottom surface of the fixing plate 509, and the fixing seat 5012 is arranged on the top surface of the push plate 503; one end of the guide shaft 5010 is connected to the fixing seat 5012, and the other end of the guide shaft 5010 passes through the guide sleeve 5011 and the fixing plate 509 in sequence along the vertical direction and is connected to the fixing plate 509 through a nut; one end of the shock absorbing spring 5013 is connected to the fixing seat 5012, and the other end of the shock absorbing spring 5013 is connected to the guide sleeve 5011. The push drive device 502 drives the fixing plate 509 to reciprocate in the vertical direction, which can drive the push plate 503 to reciprocate in the vertical direction. In this process, the guide shaft 5010 plays a guiding role and cooperates with the shock absorbing spring 5013 to absorb the vibration from the push plate 503 and the fixing plate 509. Preferably, the guide shaft 5010 and the fixing plate 509 of this embodiment are fixedly connected via a locking nut.

[0058] The working principle of the pushing mechanism 5 is as follows: when the boxed material is transported from the discharge end of the second conveying mechanism 4 to the pushing conveyor belt 504 of the pushing mechanism 5, the clamping drive devices 507 of the two clamping units respectively drive their respective clamping plates 508 to move in the horizontal direction, so that the two clamping plates 508 are close to each other to clamp the box body 100, and then the pushing drive device 502 drives the pushing plate 503 to move downward. At this time, the vibrator 505 drives the vibration block 506 to vibrate, and the continuously vibrating vibration block 506 acts on the bottom of the box body 100, thereby achieving complete separation of the hot pot base from the bottom of the box body 100, and then the boxed material is driven by the pushing conveyor belt 504 to move to the demolding mechanism 6 for demolding.

[0059] Finally, the boxed material further separated by the pushing mechanism 5 will enter the demoulding mechanism 6, and the box body 100 and the solidified material will be completely separated by the demoulding mechanism 6.

[0060] For details, please refer to Figure 7 The demoulding mechanism 6 includes a plurality of demoulding units arranged in sequence along the conveying direction of the boxed materials, so as to realize demoulding of a plurality of boxed materials at the same time, so as to further improve the production efficiency. In this embodiment, two demoulding units are arranged.

[0061] The demoulding unit includes a demoulding bracket 601, a demoulding drive device I 602, a demoulding drive device II 603, a demoulding column 604 and a demoulding conveyor belt 605. The demoulding drive device I 602 is installed on the demoulding bracket 601. The demoulding drive device I 602 is used to drive the demoulding drive device II 603 to reciprocate in the vertical direction. The demoulding drive device II 603 is used to drive the demoulding column 604 to rotate in a vertical plane. The free end of the demoulding column 604 is provided with an adsorption device 606 for adsorbing the box body 100. The demoulding conveyor belt 605 is located below the adsorption device 606 to realize the separate conveying of boxed materials. In this embodiment, the output end of the demoulding drive device I602 is connected to the connecting frame 607, and the demoulding drive device II 603 is installed on the connecting frame 607. The demoulding drive device I 602 drives the connecting frame 607 to reciprocate in the vertical direction, thereby driving the demoulding drive device II 603 to reciprocate in the vertical direction.

[0062] It should be noted that the demoulding drive device I 602 of the present embodiment can be any linear drive device or other combined mechanism that can perform linear reciprocating motion, such as a cylinder, a hydraulic cylinder, an electric push rod, etc. The demoulding drive device I602 of the present embodiment is preferably a cylinder with stable and efficient operation process; and the demoulding drive device II 603 is also any device that can drive the demoulding column 604 to rotate in a vertical plane, such as a motor, a rotary cylinder, etc. The demoulding drive device II 603 of the present embodiment is preferably a rotary cylinder with stable operation process and high control accuracy.

[0063] The adsorption device 606 of this embodiment adopts a vacuum suction cup with strong adsorption force, and the vacuum suction cup is connected to an external vacuum generator. When the vacuum suction cup contacts the bottom of the box body 100, the vacuum suction cup is evacuated by the external vacuum generator, so that the box body 100 is firmly adsorbed by the vacuum suction cup. The whole process is simple and stable, and the problem of the box body 100 falling during the transfer process is avoided.

[0064] In addition, in order to facilitate the conveying of the separated box body 100, the demoulding unit also includes a discharge channel 608 provided on the demoulding bracket 601, the discharge channel 608 is located above the demoulding conveyor belt 605 and is inclined, and the discharge channel 608 is used to receive the box body 100 adsorbed by the adsorption device 606. It should be noted that in actual implementation, a notch for accommodating the demoulding column 604 needs to be provided at the inlet end of the discharge channel 608 to avoid interference between the demoulding column 604 and the discharge channel 608 when the demoulding column 604 rotates under the drive of the demoulding driving device II 603.

[0065] The working principle of the demoulding mechanism 6 is as follows: when the boxed material transmitted from the pushing mechanism 5 moves to the demoulding conveyor belt 605 and is located directly below the adsorption device 606, the adsorption device 606 is facing the box body 100 of the boxed material; then the demoulding driving device I 602 drives the demoulding driving device II 603 to move downward, thereby driving the adsorption device 606 to move downward. Since the box body 100 is in a downward opening state at this time, and the box body 100 is completely separated from the hot pot base, the adsorption device 606 can be used to directly adsorb the box body 100; after the adsorption device 606 adsorbs the box body 100, the demoulding driving device I 602 drives the demoulding driving device II 603 to move upward for a distance, so that the box body 100 is completely separated from the hot pot base, and then the demoulding driving device II 603 drives the demoulding column 604 to rotate a certain angle in the vertical plane, and the box body 100 can be driven to rotate to the discharge channel 608 through the adsorption device 606 for discharge, and the separated hot pot base is transported to the packaging station by other conveying mechanisms for packaging. It can be seen that this embodiment can save labor costs by adopting a purely mechanical mechanism to take away the box body 100 of the boxed material after separation, and the entire demoulding process is simple and fast, which can further improve production efficiency. Based on the discharge channel 608 of this embodiment, it is arranged directly above the demoulding conveyor belt 605. Therefore, in actual work, the demoulding drive device II 603 needs to drive the demoulding column 604 to rotate 180° in the vertical plane, so that the box body 100 can be transferred to the discharge channel 608.

[0066] In combination with the above records, the present embodiment also provides a demolding method, using the demolding machine described above, the demolding process includes: placing the boxed material with the opening facing upward on the first conveying mechanism 1, and the first conveying mechanism 1 conveys the boxed material to the separation mechanism 2; the separation mechanism 2 separates the inner wall of the box body 100 from the outer wall of the solidified material, and conveys the separated boxed material to the flipping mechanism 3; the flipping mechanism 3 flips the boxed material with the opening facing upward to a state with the opening facing downward, and conveys the boxed material with the opening facing downward to the second conveying mechanism 4; the second conveying mechanism 4 conveys the boxed material with the opening facing downward to the pushing mechanism 5; the pushing mechanism 5 completely separates the bottom of the box body 100 from the solidified material, and continues to convey the boxed material to the demolding mechanism 6; the demolding mechanism 6 completely separates the box body 100 from the solidified material, and the separated box body 100 is conveyed away from the discharge channel 608, while the solidified material is conveyed to the packaging station for packaging through other conveying mechanisms.
