Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a material pushing mechanism for pushing vacuum-packed root vegetables from a conveyor belt to a designated position. Background Technology

[0002] Currently, the most common method used in the pre-processed vegetable industry is to use vacuum suction cups to directly pick up materials from the conveyor belt. However, when encountering materials with uneven surfaces, such as vacuum-packed root vegetables, the materials can easily detach from the suction cups, affecting the success rate of gripping. As for the method of gripping with rigid claws, since the claws need to extend into the bottom of the material to grip it, the conveyor belt will interfere with the claws and make it impossible to grip the material from the conveyor belt. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a material pushing mechanism to solve the problem that the suction cup has a low success rate in grasping materials with uneven surfaces, which affects the work efficiency.

[0004] To achieve the above and other related objectives, this utility model provides a material pushing mechanism, including a blocking unit disposed at the end of the conveyor belt for blocking material transported by the conveyor belt; a lateral pushing unit disposed on one side of the conveyor belt; a carrying platform disposed on the other side of the conveyor belt, wherein the lateral pushing unit is used to push the material on the conveyor belt onto the carrying platform, wherein the width of the carrying platform is smaller than the width of the material; and a control unit, wherein the blocking unit and the lateral pushing unit are communicatively connected to the control unit.

[0005] Furthermore, the blocking unit includes a mounting bracket disposed at the end of the conveyor belt, a blocking plate disposed on the mounting bracket, the blocking plate being located above the conveyor belt, the upper end of the blocking plate being hinged to the mounting bracket, the lower end of the blocking plate extending downward, and the lower end of the blocking plate having a gap with the surface of the conveyor belt; a limit sensor disposed on the mounting bracket, the limit sensor being located behind the blocking plate, and a set gap being between the limit sensor and the blocking plate, the limit sensor being communicatively connected to the control unit.

[0006] Furthermore, the lower end of the blocking plate is connected to the mounting bracket through a limiting mechanism. The limiting mechanism causes the blocking plate to deflect to the rearward side at a certain angle, and the limiting mechanism can restrict the blocking plate from rotating freely to the outside.

[0007] Furthermore, the limiting mechanism includes first oblong holes at the left and right ends of the blocking plate, and connecting screws are inserted into both first oblong holes. The first end of the connecting screw is connected to the mounting bracket, and the second end of the connecting screw is provided with a first limiting flange. The first limiting flange is used to restrict the blocking plate from rotating freely outward.

[0008] Furthermore, the upper end of the baffle plate is hinged to the mounting bracket via a first hinge.

[0009] Furthermore, the lateral push unit includes a mounting frame, on which a push cylinder is provided. The push cylinder is located above the conveyor belt and has a push plate. The push cylinder can drive the push plate to move back and forth in a direction close to the support platform and in a direction away from the support platform. The push cylinder is communicatively connected to the control unit.

[0010] Furthermore, the carrying platform is equipped with a detection unit, which is used to detect whether there is material on the carrying platform, and the detection unit is communicatively connected to the control unit.

[0011] Furthermore, the support platform includes a support main board with a mounting port in the middle. The detection unit includes a pressure plate disposed in the mounting port. The first side of the pressure plate is hinged to the support main board. The bottom of the support main board is provided with a photoelectric switch and a connecting plate. A spring is sandwiched between the bottom of the second side of the pressure plate and the connecting plate. A signal trigger plate is provided at the bottom of the pressure plate. The signal trigger plate corresponds vertically to the photoelectric switch. The photoelectric switch is communicatively connected to the control unit.

[0012] Furthermore, a positioning screw is provided at the bottom of the second side of the pressure plate. The first end of the positioning screw is threadedly connected to the pressure plate. A second oblong hole is provided on the connecting plate. The second end of the positioning screw extends downward and passes through the second oblong hole. The second end of the positioning screw is provided with a second limiting flange. The second limiting flange contacts the bottom surface of the connecting plate. The spring is sleeved on the positioning screw. The upper end of the spring contacts the bottom surface of the pressure plate, and the lower end of the spring contacts the top surface of the connecting plate.

[0013] Furthermore, the first side of the pressure plate is hinged to the main support plate via a second hinge.

[0014] As described above, the material pushing mechanism of this utility model has the following beneficial effects: During operation, when the material is conveyed to the end of the conveyor belt, the blocking unit located at the end of the conveyor belt will block the material. At the same time, the blocking unit will send a signal to the control unit. The control unit controls the lateral pushing unit to start according to the signal sent by the blocking unit, so as to push the material blocked by the blocking unit onto the carrying platform. Since the width of the carrying platform is smaller than the width of the material, the two sides of the material will protrude from the two sides of the carrying platform, thereby facilitating the rigid gripper to grasp the material. Compared with the prior art, the material pushing mechanism of this utility model can push materials that are difficult for suction cups to pick up from the conveyor belt to the carrying platform first, and then the rigid gripper will grasp the material pushed onto the carrying platform, thereby greatly improving the success rate of material grasping and improving work efficiency.

[0024] Please see Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0025] This utility model provides a material pushing mechanism for pushing vacuum-packed root vegetables from a conveyor belt to a designated position. Specifically, for example... Figure 1As shown, the material pushing mechanism includes a blocking unit 10, a lateral pushing unit 20, a carrying platform 30, and a control unit. The blocking unit 10 is located at the end of the conveyor belt 100 and is used to block the material 200 transmitted by the conveyor belt 100. The lateral pushing unit 20 is located on one side of the conveyor belt 100, and the carrying platform 30 is located on the other side of the conveyor belt 100. The lateral pushing unit 20 is used to push the material 200 on the conveyor belt 100 onto the carrying platform 30. Specifically, the width of the carrying platform 30 is smaller than the width of the material. Both the blocking unit 10 and the lateral pushing unit 20 are communicatively connected to the control unit.

[0026] The beneficial effects of the material lateral pushing mechanism of this utility model are as follows: During operation, when the material 200 is conveyed to the end by the conveyor belt 100, the blocking unit 10 located at the end of the conveyor belt 100 will block the material 200. At the same time, the blocking unit 10 will send a signal to the control unit. The control unit controls the lateral pushing unit 20 to start according to the signal sent by the blocking unit 10, so as to push the material blocked by the blocking unit 10 onto the carrying platform 30. Since the width of the carrying platform 30 is smaller than the width of the material, the two sides of the material will protrude from the two sides of the carrying platform 30, thereby facilitating the rigid gripper to grasp the material. Compared with the prior art, the material lateral pushing mechanism of this utility model can push materials that are difficult for suction cups to pick up from the conveyor belt to the carrying platform first, and then the rigid gripper will grasp the material pushed onto the carrying platform, thereby greatly improving the success rate of material grasping and improving work efficiency.

[0027] Furthermore, such as Figure 2 and Figure 3As shown, in this embodiment, the blocking unit 10 includes a mounting bracket 11 disposed at the end of the conveyor belt 100. A blocking plate 12 is provided on the mounting bracket 11. Specifically, the blocking plate 12 is located above the conveyor belt 100, and the upper end of the blocking plate 12 is hinged to the mounting bracket 11. The lower end of the blocking plate 12 extends downward, and there is a gap between the lower end of the blocking plate 11 and the surface of the conveyor belt 100. A limit sensor 13 is also provided on the mounting bracket 11. The limit sensor 13 is located on the rear side of the blocking plate 12 (i.e., the side with the same conveying direction as the conveyor belt), and there is a set gap between the limit sensor 13 and the blocking plate 12. The limit sensor 13 is communicatively connected to the control unit. With this configuration, when the conveyor belt 100 transports material 200 to the position of the blocking unit 10, the blocking plate 12 will block the material from continuing to move. At the same time, the material will also exert a backward pushing force on the blocking plate 12, so that the lower end of the blocking plate 12 can rotate backward at a certain angle with the hinge point between its upper end and the mounting bracket 11 as the fulcrum. Then, the blocking plate 12 will trigger the limit sensor located on the rear side of the blocking plate 12. The limit sensor will then send a signal to the control unit that the material has arrived. Based on this signal, the control system controls the lateral push unit 20 to start pushing the material.

[0028] Furthermore, considering that after the material is pushed away, the baffle 12 will swing forward and reset due to its own gravity, and due to inertia, the baffle will swing back and forth, which may cause false triggering of the limit sensor 13. Therefore, preferably, as Figure 2 As shown, in this embodiment, the lower end of the baffle plate 12 is connected to the mounting bracket 11 via a limiting mechanism. This limiting mechanism causes the baffle plate 12 to deflect backward at a certain angle, i.e., the baffle plate 12 forms a certain angle with the vertical direction, and the limiting mechanism restricts the baffle plate 12 from rotating freely outward. With this configuration, when the material is conveyed to the position of the baffle plate 12 by the conveyor belt 100, since the limiting mechanism does not restrict the baffle plate 12 from rotating backward, after the baffle plate 12 blocks the material, the material will push the baffle plate 12 to rotate backward at a certain angle, thereby triggering the limiting sensor 13. After the material is pushed away, the baffle plate 12 returns to its initial position (deflected backward at a certain angle with the vertical direction) due to its own gravity. That is, the limiting mechanism restricts the baffle plate 12 from rotating freely outward, thus preventing the baffle plate 12 from swinging back and forth and causing false triggering of the limiting sensor 13 when the material leaves the baffle plate 12. Preferably, under normal conditions, the blocking plate 12 can be deflected to the rearward side by 8°~10° through the limiting mechanism.

[0029] Furthermore, such as Figure 3As shown, in this embodiment, the limiting mechanism includes first oblong holes at both ends of the baffle plate 12. Connecting screws 121 pass through each of the two first oblong holes. The first end of each connecting screw 121 is connected to the mounting bracket 11, and the second end of each connecting screw 121 has a first limiting flange 1211. The first limiting flange 1211 is used to restrict the baffle plate 12 from rotating freely outwards, i.e., in the direction opposite to the conveyor belt's conveying direction. Specifically, as... Figure 3 As shown, in this embodiment, both the left and right ends of the baffle plate 12 are provided with rearward bent connecting ear plates 122, and the waist-shaped hole is provided on the connecting ear plate 122.

[0030] Specifically, such as Figure 3 As shown, in this embodiment, the upper end of the baffle plate 12 is hinged to the mounting bracket 11 via the first hinge 123.

[0031] Furthermore, such as Figure 1 As shown, in this embodiment, the lateral push unit 20 includes a mounting frame 21, which is equipped with an upper push cylinder 22. The push cylinder 22 is located above the conveyor belt 100, and a pusher plate 221 is provided on the push cylinder 22. The push cylinder 22 can drive the pusher plate 221 to move back and forth in the direction close to the support platform 30 and in the direction away from the support platform 30. Specifically, the push cylinder 22 is communicatively connected to the control unit. During operation, when the blocking plate 12 triggers the limit sensor 13, the limit sensor 13 sends a material arrival signal to the control unit. Based on the signal sent by the limit sensor 13, the control unit controls the push cylinder 22 to start. The push cylinder 22 drives the pusher plate 221 to move in the direction close to the support platform 30, thereby pushing the material 200 onto the support platform 30. Then, the push cylinder 22 pulls the pusher plate 221 to move in the direction away from the support platform 30 to reset the pusher plate 221 to wait for the next material.

[0032] Furthermore, in this embodiment, a detection unit is provided on the support platform 30. This detection unit is used to detect whether there is material on the support platform 30, and it is communicatively connected to the control unit. In actual operation, a rigid gripper used to grasp the material can also be connected to the control system. With this configuration, when the material is pushed onto the support platform 30, the detection unit sends the material arrival information to the control unit. Then, the control unit controls the rigid gripper to automatically grasp the material pushed onto the support platform 30 based on this information. This achieves a high degree of automation and ensures the continuity of the operation.

[0033] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the support platform 30 includes a support main board 31, which has a mounting port in the middle. The detection unit includes a pressure plate 311, which is disposed in the mounting port. Specifically, the first side of the pressure plate 311 is hinged to the support main board 31. A photoelectric switch 312 and a connecting plate 313 are provided at the bottom of the support main board 31. A spring 314 is sandwiched between the bottom of the second side of the pressure plate 311 and the connecting plate 313. A signal trigger plate 315 is provided at the bottom of the pressure plate 311. The signal trigger plate 315 corresponds vertically to the photoelectric switch 312. Specifically, the photoelectric switch 312 is communicatively connected to the control unit. When the material is pushed onto the support platform 30, i.e. the support main board 31, the material will press on the pressure plate 331 on the support main board 31. This will cause the second side of the pressure plate 311 to rotate downward with the hinge point between its first side and the support main board 31 as the fulcrum. This will then drive the signal trigger plate 315 at the bottom of the pressure plate 311 to move downward. The signal trigger plate 315 will then trigger the photoelectric switch 312, thereby realizing the detection of the material's arrival. The structure is simple and the detection is highly stable.

[0034] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the first side of the pressure plate 311 is hinged to the main support plate 31 via the second hinge 3111.

[0035] Furthermore, to ensure the stability of the spring 314 disposed between the pressure plate 311 and the connecting plate 313, preferably, as follows: Figure 5 As shown, in this embodiment, a positioning screw 316 is provided at the bottom of the second side of the pressure plate 311. The first end of the positioning screw 316 is threadedly connected to the pressure plate 311. A second oblong hole is provided on the connecting plate 313. The second end of the positioning screw 316 extends downward and passes through the second oblong hole. The second end of the positioning screw 316 is provided with a second limiting flange 3161, which contacts the bottom surface of the connecting plate 313. The spring 314 is sleeved on the positioning screw 316. The upper end of the spring 314 contacts the bottom surface of the pressure plate 311, and the lower end of the spring 314 contacts the top surface of the connecting plate 313. This arrangement ensures the stability of the spring 314 sandwiched between the pressure plate 311 and the connecting plate 313. Furthermore, the second limiting flange 3161 prevents the pressure plate 311 from wobbling downwards after the material is removed from it.

[0036] In summary, the material pushing mechanism of this invention can first push materials that are difficult for suction cups to pick up from the conveyor belt to the carrying platform, and then use rigid grippers to clamp the materials pushed onto the carrying platform, thereby greatly improving the success rate of material grabbing and increasing work efficiency. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
