Description

Technical Field

[0001] The utility model relates to the technical field of fork-throwing and fork-filling, in particular to a double-row multi-stage pipeline buffer fork-filling device. Background Art

[0002] When producing barreled instant noodles or similar products, forks and other materials need to be placed in the barrel. Using a fork-throwing machine can free up manual labor and allow for efficient material delivery. However, the fork-throwing machine may have a missing or leaking spoon during production. In this regard, the patent document with application number CN202322052628.3 discloses an automatic fork-filling device for a fork-throwing machine, which mainly realizes the fork-filling function of the fork-throwing machine through a two-stage fork-filling device of a primary fork-filling device and a secondary fork-filling device, improves the accuracy of fork-throwing, and eliminates the occurrence of missing forks. However, the defects of this solution are: first, the primary fork-filling device and the secondary fork-filling device are relatively independent, and the correlation between the two fork-filling devices is poor. They need to be controlled from the outside using a PC and cannot be automatically sensed for fork filling. Second, the top three-stage V-shaped door switch of the primary fork-filling device is overlapped and arranged in three layers, resulting in a bloated structure and inconvenient control. Therefore, the above two points will affect the accuracy and stability of the equipment when filling forks, and it is also inconvenient for subsequent inspection and maintenance.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] The utility model provides a double-row multi-stage pipeline cache fork filling device, including a frame, on which a fork feed unit, a fork branching unit, a first-level fork filling unit, a second-level fork filling unit and a third-level fork storage unit are sequentially arranged according to the forward direction of the fork during fork filling. The fork branching unit includes a drop port cooperating with the first-level fork filling unit. Two fork feed units are provided, and the two fork feed units are arranged on both sides of the drop port so that when fork filling, the two fork feed units alternately feed materials to the drop port; the drop port and the discharge port of the third-level fork storage unit are provided with a fork shortage sensor, and the frame is also provided with a control box to control the fork dropping process when fork filling.

[0006] The fork feed unit includes a fork feed motor and a fork feed frame. The fork feed motor is installed on the frame. The fork feed motor drives the fork feed frame to perform reciprocating motion so that the fork feed frame moves closer to or away from the blanking port. Several fork feed cylinders are installed on the fork feed frame. The telescopic rod of the fork feed cylinder is provided with a material shifting piece that cooperates with the blanking port. The fork feed motor and the fork feed cylinder are connected to the control box.

[0007] The first-level fork compensation unit includes several oblique tubes that cooperate with the drop-out port, and the oblique tubes are arranged in two rows in parallel. The feed ports of the oblique tubes are arranged in a matrix, and the discharge ports of the oblique tubes are arranged on the same plane. The oblique tubes are provided with two fork-blocking mechanisms in sequence along the fork-dropping direction near the discharge port; the fork-blocking mechanism includes a fork-blocking cylinder and a fork-blocking plate. The fork-blocking cylinder is installed on the oblique tube, and the fork-blocking cylinder is connected to the control box. The fork-blocking cylinder drives the fork-blocking plate to flip to achieve the opening and closing of the channel in the oblique tube.

[0008] The secondary fork compensation unit includes several secondary fork compensation pipes that cooperate with the oblique pipe, and the tertiary fork storage unit includes several tertiary fork storage pipes that cooperate with the secondary fork compensation pipe, and the tertiary fork storage pipe is made of transparent material; a fork drop buffer V door is provided on the frame between the discharge port of the oblique pipe and the feed port of the secondary fork compensation pipe, between the discharge port of the secondary fork compensation pipe and the feed port of the tertiary fork storage pipe, and at the discharge port of the tertiary fork storage pipe, and the fork drop buffer V door is connected to the control box to control the opening and closing of the fork drop buffer V door through the control box.

[0009] The beneficial effects of the utility model are:

[0010] The utility model provides fork shortage sensors at the drop port and the discharge port of the three-stage fork storage unit, which can automatically sense fork shortage and fork missing conditions in the entire fork compensation device at the head and tail. At the same time, the fork feeding unit can also alternately feed materials to the inclined pipes arranged in parallel. When a fault occurs in one workstation, the machine will not stop, which is more stable. At the same time, it is matched with the control box on the frame to automatically control and sense the fork dropping process of the entire fork compensation device, automatically and efficiently complete the fork compensation action, and ensure the accuracy and stability of fork compensation.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] As shown in the figure, the present invention provides a double-row multi-stage pipeline buffer fork filling device, including a frame 1, on which a fork feed unit 2, a fork branching unit 3, a first-level fork filling unit 4, a second-level fork filling unit 5 and a third-level fork storage unit 6 are arranged in sequence according to the forward direction of the fork when filling the fork. It should be further explained that in order to save space and increase the compactness of the equipment, the fork feed unit 2, the fork branching unit 3 and the first-level fork filling unit 4 can be arranged in multiple layers as needed (two layers are taken as an example in the figure of this embodiment). Specifically, the fork feed unit 2 includes a fork feed motor 21 and a fork feed frame 22. The fork motor 21 is installed on the frame 1, and the fork motor 21 drives the fork frame 22 to do reciprocating motion so that the fork frame 22 is close to or away from the blanking port 31. A number of fork cylinders are installed on the fork frame 22, and a material-shifting piece 23 cooperating with the blanking port 31 is provided on the telescopic rod of the fork cylinder. The fork motor 21 and the fork cylinder 24 are connected to the control box 8; the fork unit 3 includes a blanking port 31 cooperating with the first-level fork compensation unit 4; there are two fork units 2, and the two fork units 2 are arranged on both sides of the blanking port 31, so that when the fork is compensated, the two fork units 2 move toward the blanking port 31. The material port 31 is alternately fed; at the same time, a fork shortage sensor 7 is provided at the material drop port 31 and the discharge port of the three-stage fork storage unit 6, and a control box 8 is also provided on the frame 1 to control the fork dropping process when the fork is supplemented. Therefore, the first-stage fork supplementing unit 4 includes a plurality of inclined tubes 41 cooperating with the material drop port 31, and the plurality of inclined tubes 41 are arranged in two rows in parallel. The material feed ports of the plurality of inclined tubes 41 are arranged in a matrix, and the material discharge ports of the plurality of inclined tubes 41 are arranged on the same plane. The inclined tubes 41 are provided with two fork blocking mechanisms 42 in sequence along the fork dropping direction near the discharge port; The first-stage fork compensation unit 5 includes a plurality of second-stage fork compensation pipes 51 that cooperate with the oblique pipe 41, and the third-stage fork storage unit 6 includes a plurality of third-stage fork storage pipes 61 that cooperate with the second-stage fork compensation pipes 51. On the frame 1, a fork drop buffer V-gate 11 is provided between the discharge port of the oblique pipe 41 and the feed port of the second-stage fork compensation pipe 51, between the discharge port of the second-stage fork compensation pipe 51 and the feed port of the third-stage fork storage pipe 61, and at the discharge port of the third-stage fork storage pipe 61. The fork drop buffer V-gate 11 is connected to the control box 8 so that the opening and closing of the fork drop buffer V-gate 11 can be controlled by the control box 8.In this way, during the normal fork filling process, the material fork first falls from the material box on the frame 1 onto the conveyor belt, and then the fork feeding motor 21 drives the fork feeding frame 22 to approach the blanking port 31, and then the telescopic rod of the fork feeding cylinder 24 carries the material shifting piece 23 to approach the material fork, and then shifts the fork to the blanking port 31 and falls into the corresponding oblique tube 41. In the process of the fork passing through the discharge port of the oblique tube 41, the two fork blocking mechanisms 42 are opened in sequence to allow the fork to pass, and then the control box 8 controls the discharge port of the oblique tube 41 and the material shifting piece 23. The fork buffer V-gate 11 between the feed port of the secondary fork filling pipe 51 is opened, and the fork falls into the secondary fork filling pipe 51. Then the control box 8 controls the fork buffer V-gate 11 between the discharge port of the secondary fork filling pipe 51 and the feed port of the tertiary fork storage pipe 61 to open, so that the fork falls from the secondary fork filling pipe 51 into the tertiary fork storage pipe 61. Finally, the control box 8 controls the fork buffer V-gate 11 at the discharge port of the tertiary fork storage pipe 61 to open so that the fork falls out of the tertiary fork storage pipe 61 to complete the filling process. Fork operation; During this process, the entire fork drop process is automatically controlled by the control box 8. Then, in order to automatically sense whether it is necessary to add forks, a low fork sensor 7 is set at the drop port 31 and the discharge port of the three-stage fork storage unit 6. Specifically, the drop port 31 is provided with a low fork sensor 7 at each feed port that cooperates with the oblique tube 41 to transmit the information of the low fork and the dropped fork at the drop port 31 to the control box 8. Then the control box 8 can accurately control the fork feed motor 21 and the corresponding fork feed cylinder 24 to complete the fork addition, and then the corresponding control completes the steps in the above-mentioned normal fork drop process; The low fork sensor 7 set at the discharge port of the three-stage fork storage unit 6 can be set in a frame shape in order to match the three-stage fork storage pipe 61. At the same time, in order to observe the situation in the three-stage fork storage pipe 61, the three-stage fork storage pipe 61 is made of transparent material. Then the fork situation information in the three-stage fork storage pipe 61 is transmitted to the control box 8, and then the control box performs the steps in the above-mentioned normal fork drop process to add forks.

[0034] Preferably, the fork-blocking mechanism 42 includes a fork-blocking cylinder 421 and a fork-blocking plate 422. The fork-blocking cylinder 421 is installed on the oblique tube 41 and is connected to the control box 8. The fork-blocking cylinder 421 drives the fork-blocking plate 422 to flip to achieve the opening and closing of the channel in the oblique tube 41. In this way, the corresponding oblique tube 41 can be independently controlled to be efficiently supplemented with forks.
