Description

Technical Field

[0001] The invention relates to the technical field of non-fried instant noodle manufacturing equipment, in particular to a taking and placing device for hot air drying equipment. Background Art

[0002] The processing technology of non-fried instant noodles generally includes: mixing flour, water and other ingredients (such as salt, alkaline water, etc.) and kneading into dough. The dough is pressed into thin sheets by a noodle press and then cut into strips or blocks as needed. The cut noodles are put into a steam device for steaming to ensure that the noodles are cooked and some moisture is removed. The steamed noodles are dried by hot air drying equipment to remove moisture from the noodles. Usually, precise adjustments are made to the temperature and humidity control to ensure uniform drying. The dried noodles are cooled and finally packaged into bags and seasoning packets are added.

[0003] In order to prevent the material from falling when the mold is turned over during the transfer process, the mold needs to have upper and lower cover operation steps. Currently, the upper and lower covers are manually operated by workers, which is not only labor-intensive but also low in work efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when the mold needs to be turned over during drying in the prior art, the mold needs to have an upper cover and a lower cover operation step. At present, the upper cover and the lower cover are manually operated by workers, which not only has high labor intensity but also has low work efficiency. A pick-up and place device for hot air drying equipment is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A pick-and-place device for hot air drying equipment is used for multiple molds that need to be covered and removed. The molds include an upper cover and a lower shell. The multiple molds can be transported by a chain conveyor and pass through the hot air drying equipment in one direction. The pick-and-place device includes a conveying chain that can operate continuously and a magnetic attraction component located on the conveying chain. The conveying chain includes a cover-covering station located at the front end of the hot air drying equipment and a cover-removing station located at the rear end of the hot air drying equipment. The magnetic attraction component is located at the cover-covering station and can buckle the upper cover on the corresponding lower shell. The magnetic attraction component is located at the cover-removing station and can remove the upper cover from the corresponding lower shell.

The picking and placing device includes a blocking rod located at the upper cover station, and the blocking rod can separate the upper cover adsorbed by the magnetic suction component from the magnetic suction component when the upper cover passes through the first turning position.

[0008] The conveying chain at least includes a continuous second descending portion and a second ascending portion, and the decapping station is located at a second turning position downstream of the second descending portion and upstream of the second ascending portion. The magnetic suction component located at the second turning position can magnetically absorb the upper cover to separate the upper cover from the lower shell at the decapping station.

[0009] The conveying chain at least includes a avoidance portion, wherein the upstream of the avoidance portion is connected to the downstream of the first ascending portion, and the downstream of the avoidance portion is connected to the upstream of the second descending portion, and the avoidance portion is used to avoid the hot air drying equipment.

[0010] The conveying chain at least includes a reflow part and a first descending part. The upstream of the reflow part is connected to the downstream of the second ascending part, the downstream of the reflow part is connected to the upstream of the first descending part, and the downstream of the first descending part is connected to the upstream of the parallel part. The reflow part, the first descending part, the parallel part, the first ascending part, the avoidance part, the second descending part and the second ascending part are a continuous annular structure.

[0011] The magnetic attraction assembly includes a support shaft, a support block rotatably connected to the support shaft, a connecting rod fixed to the bottom of the support block, and a first magnetic block fixed to the bottom of the connecting rod. The support shaft is arranged along the width direction of the conveyor chain and the two are fixed. The upper cover is at least partially made of ferromagnetic metal or at least partially has a second magnetic block that is magnetically attracted to the first magnetic block.

[0012] Each of the molds has at least two lower shells and corresponding upper covers. The multiple upper covers of the same mold have multiple second magnetic blocks with N poles and S poles alternately distributed. The magnetic attraction component has multiple first magnetic blocks with S poles and N poles alternately distributed, and each first magnetic block corresponds to a second magnetic block.

[0013] The chain conveyor is located inside the hot air drying device as a drying station. Located at the drying station, the hot air drying device can blow convection hot air to the mold, and the mold can be rolled at the drying station.

[0014] The chain conveyor includes a plurality of shafts that can move and rotate following the chain, and a plurality of molds are installed on each of the shafts.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 7A pick-and-place device for hot air drying equipment is used for multiple molds 2 that need to be covered and removed. The molds 2 include an upper cover 9 and a lower shell 10. The multiple molds 2 can be conveyed by a chain conveyor 1 and pass through a hot air drying device 7 in one direction. The hot air drying device 7 drives the multiple molds 2 to continuously pass through the hot air drying device 7. The hot air drying device 7 generates a hot air flow to dry the instant noodles in the molds 2. The pick-and-place device includes a conveying chain 100 that can operate continuously and a magnetic suction component located on the conveying chain 100. The conveying chain 100 includes a cover-covering station 3 located at the front end of the hot air drying device 7 and a cover-removing station 5 located at the rear end of the hot air drying device 7. The magnetic suction component is located at the cover-covering station 3 and can buckle the upper cover 9 on the corresponding lower shell 10. The magnetic suction component is located at the cover-removing station 5 and can remove the upper cover 9 from the corresponding lower shell 10.

[0027] When the device is working, the conveyor chain 100 drives the magnetic suction component to operate continuously. When the magnetic suction component moves to the upper cover station 3, the upper cover 9 can be buckled on the corresponding lower shell 10. The magnetic suction component is located at the cover removal station 5 and can remove the upper cover 9 from the corresponding lower shell 10. In this way, the device can realize continuous upper and lower cover operations on the lower shell 10 of the mold 2, reducing the tedious process of workers' upper and lower cover and carrying, and reducing labor intensity.

[0028] refer to Figure 1 , Figure 2 The conveying chain 100 at least includes a continuous parallel portion 103 and a first rising portion 104. The upper cover station 3 is located at a first turning position downstream of the parallel portion 103 and upstream of the first rising portion 104. The picking and placing device includes a blocking rod 202 located at the upper cover station 3. The blocking rod 202 can separate the upper cover 9 adsorbed by the magnetic attraction component from the magnetic attraction component when the upper cover 9 passes through the first turning position.

[0029] It should be noted that the movement speed of the conveyor chain 100 of the device is the same as the transmission speed of the mold (2).

[0030] When located in the parallel portion 103, each upper cover 9 corresponds to a lower shell 10 below, and the device is provided with a first turning position. When the magnetic suction component passes through the first turning position, the magnetic suction component changes from horizontal movement to vertical upward movement. During the horizontal movement, the upper cover 9 adsorbed by the magnetic suction component moves to the bottom of the blocking rod 202. When the magnetic suction component moves upward, the blocking rod 202 has a blocking effect on the upper cover 9. The upper cover is separated from the magnetic suction component under the blocking action of the blocking rod 202. Since each upper cover 9 corresponds to a lower shell 10 below, when the upper cover 9 is separated from the magnetic suction component, it is sealed on the upper mouth of the lower shell 10 to form a closed mold 2.

[0031] The conveyor chain 100 at least includes a continuous second descending portion 106 and a second ascending portion 107. The decapping station 5 is located at a second turning position downstream of the second descending portion 106 and upstream of the second ascending portion 107. The magnetic suction component located at the second turning position can magnetically absorb the upper cover 9 and separate the upper cover 9 located at the decapping station 5 from the lower shell 10.

[0032] Since the magnetic attraction component moves downward first and then upward, when the magnetic attraction component moves to the second turning position, the upper cover 9 above the lower shell 10 is sucked away by the action of the magnetic force, and the lower cover operation is completed.

[0033] The conveyor chain 100 at least includes an avoidance portion 105, the upstream of the avoidance portion 105 is connected to the downstream of the first ascending portion 104, and the downstream of the avoidance portion 105 is connected to the upstream of the second descending portion 106. The avoidance portion 105 is used to avoid the hot air drying equipment 7. The avoidance portion 105 can be provided to reserve placement space for the hot air drying equipment 7.

[0034] refer to Figure 1 , Figure 2 The conveying chain 100 at least includes a reflux portion 101 and a first descending portion 102. The upstream of the reflux portion 101 is connected to the downstream of the second ascending portion 107, the downstream of the reflux portion 101 is connected to the upstream of the first descending portion 102, and the downstream of the first descending portion 102 is connected to the upstream of the parallel portion 103. The reflux portion 101, the first descending portion 102, the parallel portion 103, the first ascending portion 104, the avoidance portion 105, the second descending portion 106, and the second ascending portion 107 are a continuous annular structure. The entire transmission process forms a circular working mode, so that continuous upper and lower cover operations can be carried out without the intervention of workers.

[0035] The magnetic attraction assembly includes a support shaft 108, a support block 109 rotatably connected to the support shaft 108, a connecting rod 200 fixed to the bottom of the support block 109, and a first magnetic block 201 fixed to the bottom of the connecting rod 200. The support shaft 108 is arranged along the width direction of the conveyor chain 100 and the two are fixed. The upper cover 9 is at least partially made of ferromagnetic metal or at least partially has a second magnetic block that is magnetically attracted to the first magnetic block 201. The first magnetic block 201 is suspended below the support shaft 108, and the first magnetic block 201 is rotatably connected to the support shaft 108 through the connecting rod 200 and the support block 109, so that the first magnetic block 201 is always located at the bottom, and the structure is simple and not easy to be damaged.

[0036] Each mold 2 has at least two lower shells 10 and corresponding upper covers 9. The multiple upper covers 9 of the same mold 2 have multiple second magnetic blocks with N poles and S poles alternately distributed. The magnetic attraction component has multiple first magnetic blocks 201 with S poles and N poles alternately distributed. Each first magnetic block 201 corresponds to a second magnetic block.

[0037] The magnetic poles of the upper cover 9 of the device and the first magnetic block 201 of the magnetic attraction component are distributed alternately in S and N poles, so that each upper cover 9 can be more stably and accurately aligned with the corresponding first magnetic block 201 above, thereby improving the accuracy and stability of the magnetic attraction connection.

[0038] The chain conveyor 1 is located inside the hot air drying device 7 as the air drying station 4. Located at the air drying station 4, the hot air drying device 7 can blow convection hot air to the mold 2, and the mold 2 located at the air drying station 4 can roll. When the device is working, the instant noodles to be dried are placed in the mold 2, and the mold 2 with instant noodles is sent into the hot air drying device 7 through the chain conveyor 1. The hot air drying device 7 generates a hot air flow to dry the instant noodles in the mold 2. The mold 2 of the device has flow holes around it and can roll itself, so that the air flow can pass through the instant noodles more evenly, improving the uniformity and drying efficiency of the instant noodles. The mold 2 rolls while moving inside the hot air drying device 7, so that the instant noodles can be evenly contacted with the hot air flow all around, improving the uniformity and efficiency of drying, and helping to reduce the overall drying length of the hot air drying device 7.

[0039] The chain conveyor 1 includes a plurality of shafts 11 that can move and rotate with the chain, and a plurality of molds 2 are installed on each shaft 11. The mold 2 includes a lower shell 10 fixed to the shaft 11 and an upper cover 9 detachably connected to the lower shell 10. A gear 12 is fixed to the shaft 11, and a rack 8 is fixed in the hot air drying device 7 along the conveying direction of the mold. The gear 12 can mesh and rotate on the rack 8.

[0040] When the chain conveyor 1 drives the mold 2 on the shaft 11 to move, when the gear 12 moves to the rack 8, the gear 12 drives the mold 2 to roll under the meshing action. The structure is simple and easy to use. The number of turns of the mold 2 can be determined according to the length of the rack 8 or the number of teeth of the gear 12, which is convenient for determining the final angle of the mold 2 when it moves out of the hot air drying equipment 7.

[0041] The lower shell 10 is made of ferromagnetic metal and has an open slot 13. The upper cover 9 has a magnetic attraction portion that can be magnetically adsorbed to the lower shell 10. The upper cover 9 and the lower shell 10 are combined by magnetic attraction, and disassembly and installation are relatively simple.

[0042] As an embodiment, the lower shell 10 is at least partially installed with multiple third magnetic blocks with S poles and N poles alternately distributed. The S pole of the lower shell 10 is magnetically attracted to the N pole of the upper cover 9, and the N pole of the lower shell 10 is magnetically attracted to the S pole of the upper cover 9. The alternating distribution can make the lower shell 10 and the upper cover 9 docking more accurately.

[0043] In order to improve the docking stability, the upper cover 9 includes a main body 92, and one side of the main body 92 has an outer edge 91. The outer edge 91 can be supported on the open end of the lower shell 10, and the main body 92 can be embedded in the groove cavity 13, so that the instant noodles in the groove cavity 13 can be better positioned through the main body 92.

[0044] A positioning support frame 6 is provided on the inner side of the chain conveyor 1, and the bottom of the mold 2 located on the outer side of the rack 8 can slide on the positioning support frame 6. The device is provided with a positioning support frame 6. When the mold 2 is out of the position of the rack 8, it moves to the positioning support frame 6. The shape on the positioning support frame 6 matches the movement direction of the chain conveyor 1, so that it can be ensured that the mold 2 is in a horizontal state when it moves to the upper cover station 3, which is convenient for putting in instant noodles and placing the upper cover 9, and is in a horizontal state when it moves to the de-covering station 5, which is convenient for removing the upper cover 9 and taking it out, which is conducive to realizing automated work.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and inventive concept of the present invention by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
