[0002] When making chocolate food, a plastic stick workpiece of a specific shape needs to be placed into the groove accommodating cavity of the corresponding mold box body. Since the box body has multiple accommodating cavities, it is inefficient to manually insert the plastic stick workpieces into the box body accommodating cavities one by one, which requires a lot of manpower. Therefore, it is necessary to design a stick placing machine to realize automatic material placing.

[0003] For example, a rod placing machine as shown in publication number CN218859759U can realize the automatic placement of rod workpieces, but it still has some defects. On the one hand, the equipment structure is relatively complex, with more actions and increased difficulty in coordination, resulting in reduced reliability and stability of equipment operation. On the other hand, the various transfer mechanisms of the equipment are closely arranged with small gaps. During the horizontal transfer process, the rod workpieces will contact the plate body and produce powder impurities, which will continue to accumulate during operation. The transfer mechanisms are inconvenient to disassemble and cannot be cleaned frequently. The accumulated impurities affect the normal operation of the equipment. Utility Model Content

[0026] In order to solve the above technical problems, Figure 1-7 As shown, the utility model designs an automatic food rod material placing device which is easy to clean, comprising a frame 1, on which a conveyor line 2 and a rod placing device are arranged, the conveyor line 2 is used to convey a mold box 3 along the X direction, and limit baffles are arranged on the left and right sides of the conveyor line 2, the rod placing device is used to place a workpiece 4 into the cavity of the mold box 3, the mold box 3 is provided with a plurality of accommodating cavities which are adapted to the shape of the plastic rod workpiece 4, and the plastic rod workpiece 4 requires a certain pressure to be inserted into the accommodating cavity, and the rod placing device comprises a supporting assembly 5, a material storage assembly 6, a workpiece lifting and transferring mechanism 7, and a workpiece horizontal transferring mechanism 8.

[0027] Specifically, the support assembly 5 includes a support plate 51, a support cross bar 52, and a support longitudinal bar 53. The two groups of support cross bars 52 are arranged opposite to each other front and back. The front and rear ends of the support plate 51 are fixed on the two support cross bars 52. The two groups of support longitudinal bars 53 are symmetrically arranged left and right. The two ends of the support longitudinal bars 53 are fixedly connected to the support cross bars 52. The support plate 51 is provided with a first through hole 54. There are a plurality of first through holes 54 and they are divided into two groups and arranged side by side left and right. In this embodiment, each row is provided with eight first through holes 54. The support plate 51 is provided with a plurality of slide grooves 55 corresponding to the first through holes 54. The slide grooves 55 are used for the loading plate 81 of the workpiece horizontal transfer mechanism 8 to pass through.

[0028] The material storage assembly 6 includes a material storage plate 61 and a feed limit rod 62. The material storage plate 61 is provided with a material storage hole 63 and a second through hole 64. The first through hole 54 corresponds to the second through hole 64 up and down. The shape of each of the material storage holes 63 is adapted to the shape of the plastic rod workpiece 4. Four feed limit rods 62 symmetrical in pairs are installed above each material storage hole 63. The feed limit rods 62 are perpendicular to the material storage plate 61. The stacked plastic rod workpieces 4 are inserted between the feed limit rods 62. The rod bodies of the plastic rod workpieces 4 are limited by the feed limit rods 62 on both sides, and the plastic rod workpieces 4 located at the bottom will pass through the material storage holes 63 with matching shapes to ensure the position accuracy when landing. The material storage holes 63 play a guiding and positioning role. Through the material storage assembly 6, a large number of plastic rod workpieces 4 can be pre-stored and placed before the equipment is operated to reduce the number of refills.

[0029] The workpiece horizontal transfer mechanism 8 includes a carrier plate 81, a first cylinder 82, and a movable plate 83. The two first cylinders 82 are symmetrically arranged on the left and right sides of the support plate 51 and are fixedly connected to the support longitudinal rod 53 respectively. The piston rod of the first cylinder 82 faces the center of the support plate 51 and is fixedly connected to the movable plate 83. Several carrier plates 81 are fixedly connected to the movable plate 83. The carrier plate 81 can be moved along the Y direction by the drive of the first cylinder 82. The carrier plate 81 is provided with a limiting groove 84 adapted to the shape of the workpiece 4. The limiting groove 84 is used to prevent the workpiece 4 from being relative to the carrier plate. The displacement prevents the workpiece from falling or getting out of place during the transfer process. Initially, the first cylinder 82 is in a retracted state, and the limit groove 84 of the loading plate 81 is located below the storage hole 63 of the storage plate 61 so that the workpiece 4 can be received. The piston rod of the first cylinder 82 extends to move the loading plate 81 to the position of the first through hole 54 for the workpiece lifting and transfer mechanism 7 to grab. Compared with the initial rod placing machine, the workpiece horizontal transfer mechanism 8 is cleverly designed, and its structure and movement are simpler and more direct. The powder impurities generated by the plastic rod workpiece 4 during the transfer process are reduced, thereby improving the reliability, stability and smoothness of the equipment operation.

[0030] Of course, the plastic rod workpiece 4 will still produce certain powder impurities during the transfer process with the carrier plate 81. In order to solve this problem, a supporting portion 57 is provided at the inlet position of the chute 55 of the support plate 51. The upper surface of the supporting portion 57 is provided with a collection groove 58 and a guide slope 59. The collection groove 58 is located on the side close to the first through hole 54. One end of the guide slope 59 is connected to the collection groove 58 and the other end is inclined downward to the entrance of the chute 55. The width of the collection groove 58 is greater than the width of the guide slope 59. When the carrier plate 81 is retracted, the powder will be carried back and finally moved outward along the guide slope 59. Roll out, and the support assembly 5 also includes a powder support plate 510 and a bottom baffle 56. The two powder support plates 510 are symmetrically arranged on the left and right sides of the support plate 51. The cross-section of the powder support plate 510 is L-shaped. The powder support plate 510 is used to carry the powder impurities derived from the guide slope 59. The bottom baffle 56 is fixedly connected to the supporting longitudinal rod 53 and the support plate 51 and is located below the powder support plate 510. The bottom baffle 56 is used to receive the powder impurities derived from the powder support plate 510. The various structures cooperate with each other and are cleverly designed, so that the powder impurities can be automatically discharged in the end to avoid accumulation that affects the normal operation of the equipment.

[0031] The workpiece lifting and transfer mechanism 7 is used to take the workpiece 4 on the loading plate 81 and press the workpiece 4 into the corresponding chamber of the mold box 3 when the first through hole 54 and the second through hole 64 are connected. Specifically, the workpiece lifting and transfer mechanism 7 includes a motor 71, a screw rod 72, a lifting and moving block 73, a lifting plate 74, a suction cup connecting column 75, a suction cup 76, a fixed plate 77, and a fixed rod 78. The fixed plate 77 is arranged opposite to the material storage plate 61 in upper and lower directions and is fixedly connected to the material storage plate 61 through four fixed rods 78 symmetrical in pairs. The motor 71 is fixedly installed above the fixed plate 77, the screw rod 72 is perpendicular to the material storage plate 61 and one end thereof is connected to the output end of the motor 71, and the interior of the lifting and moving block 73 is connected to the screw rod nut through the screw rod nut. 72 cooperates, the lifting plate 74 is fixedly connected with the lifting and moving block 73, and a sliding sleeve that slides with the fixed rod 78 is installed on the lifting plate 74. A plurality of suction cups 76 correspond to the second through holes 64 respectively and are connected to the lifting plate 74 through suction cup connecting columns 75. The motor 71 drives the screw rod 72 to rotate so that the lifting plate 74 can be adjusted for lifting and lowering displacement. The transmission method of the screw rod 72 can achieve precise displacement adjustment. When the workpiece 4 moves to the first through hole 54 with the loading plate 81, the lifting plate 74 can lower the suction cup 76 to pass through the second through hole 64 and adsorb the workpiece 4 in the first through hole 54, and the lifting plate 74 drives the suction cup 76 to lift the workpiece 4, and then the loading plate 81 can be retracted and separated, and then the suction cup 76 can be pressed down.

[0032] Taking into account that although the structure of the entire rod release device has been simplified, the overall layout is still relatively compact and tight, it still needs to be cleaned after a period of use, especially the storage plate 61 and the support plate 51 structure. In order to solve this problem, the present device also includes a first flipping mechanism 9, which is used to allow the storage plate 61 to rotate relative to the support plate 51. The first flipping mechanism 9 includes a locking bolt 91, a handle 92, a support shaft 93, and a movable rod 94. The handle 92 is fixedly installed above one side of the storage plate 61, and the other side of the storage plate 61 is fixedly connected to one end of the movable rod 94, and the other end of the movable rod 94 is rotatably connected to the support shaft 93 fixedly installed on the support plate 51. The locking bolt 91 is used to prevent the storage plate 61 from loosening after locking. After the locking bolt 91 is opened, the staff can lift the storage plate 61 by the handle 92 to separate it from the support plate 51 for easy cleaning.

[0033] Furthermore, the device also includes a second flipping mechanism 10, which includes a second cylinder 101, a first articulated seat 102, a second articulated seat 103, a third articulated seat 104, and a vertical rod 105. The first articulated seat 102 is fixedly connected to one side of the frame 1, the second articulated seat 103 is located on the same side as the first articulated seat 102 and is fixedly connected to one of the supporting cross bars 52, the cylinder body of the second cylinder 101 is rotatably connected to the first articulated seat 102, the piston rod of the second cylinder 101 is rotatably connected to the second articulated seat 103, the third articulated seat 104 is fixedly connected to another supporting cross bar 52, and the vertical rod 105 is fixedly installed on the frame 1, and the vertical rod 105 is rotatably connected to the third articulated seat. When the piston rod of the second cylinder 101 is extended, the support plate 51 can be lifted relative to the conveyor line 2, so as to facilitate cleaning of the position below the support plate 51.

[0034] When the mold box 3 moves on the conveyor line 2, it needs to be accurately positioned below the rod placing device. Therefore, a positioning blocking mechanism 11 and a clamping mechanism 12 are also provided on the conveyor line 2. The positioning blocking mechanism 11 includes a third cylinder 111. Two third cylinders 111 are symmetrically arranged on the left and right sides of the conveyor line 2. The piston rod of the third cylinder faces the center of the conveyor line 2 and is connected to a block 112. The third cylinder 111 drives the block 112 to extend to block the mold box 3 on the conveyor line 2 from moving forward. The clamping mechanism 12 includes a fourth cylinder 121 and a clamping plate 122. The fourth cylinder 121 is fixedly mounted on the frame 1 and is located on one side of the conveyor line 2. The fourth cylinder 121 is arranged parallel to the third cylinder 111. The piston rod of the fourth cylinder 121 is connected to the clamping plate 122. When the mold box 3 stops moving forward, the fourth cylinder 121 drives the clamping plate 122 to extend to clamp the mold box 3. The two mechanisms cooperate to accurately limit the mold box 3 from X and Y directions.

[0035] When the workpiece 4 is lifted up to a certain height, the loading plate 81 can be retreated and separated, and at the same time return to the bottom of the storage hole 63 to take the material. Then the lifting plate 74 descends again to make the workpiece 4 pass through the second through hole 64 and the first through hole 54, and finally perform the downward pressing operation. At this time, the mold box 3 is positioned on the conveyor line 2 and the blocking mechanism 11 and the clamping mechanism 12 cooperate to limit and fix. The various mechanisms cooperate with each other to finally complete a multi-chamber box body for rapid loading. The whole process has a high degree of automation and improves efficiency.
