Description

Technical Field

[0001] The utility model relates to the technical field of packaging conveying and material sorting equipment, and more specifically to a material discharging mechanism and a material discharging and conveying device thereof. Background Art

[0002] The traditional dual servo discharging mechanism is controlled by dual servos at the two points of feeding and discharging, that is, when the first servo completes the step-by-step material receiving at the feeding point, the second servo completes the step-by-step material discharging at the discharging point, and then the first servo quickly moves to the discharging point for step-by-step material discharging, and the second servo quickly moves to the feeding point for step-by-step material receiving, and so on. This type of dual servo discharging mechanism is widely used in packaging material sorting lines.

[0003] The main function of the dual servo discharge mechanism is to balance the conveying speed between the feed conveyor belt and the feed tail rack of the packaging machine. At the same time, it can also realize the discharge and sorting of the single material conveyed by the feed conveyor belt, so that each storage grid of the dual servo discharge mechanism can store one package of materials, and then transport this package of materials to the feed tail rack of the packaging machine for packaging. For example, if three materials are stored in each storage grid of the dual servo discharge mechanism, when the packaging speed of the packaging machine is 100 packs / min, the feeding conveyor belt needs to have a conveying rate of 300 materials / min.

[0004] Since the existing dual-servo discharge mechanism has only two servos to control the feeding and discharging points, when the packaging machine packs too fast, for example, more than 220 packs / min, the interval between each pack is short, and the time left for the two servo conveying components to alternate is also short, that is, it takes another 0.27 seconds to complete the movement of the rear servo conveying component to the discharging end and the discharging action. This time cannot meet the movement and discharging of the rear servo conveying component, which will cause the phenomenon of not being able to follow up, missing packages, and wrong packages. For example, after the first servo completes the discharging, the second servo has not completed the material connection, which will cause the package to be missed. Utility Model Content

[0005] In order to overcome the defects and deficiencies in the above-mentioned prior art, the utility model provides a discharging mechanism and a discharging conveying device thereof.

[0017] Compared with the prior art, the beneficial technical effects brought by the utility model are as follows:

[0018] 1. Compared with the existing dual-servo discharging mechanism, the utility model adopts a three-servo discharging mechanism and adds a set of servo conveying components. The added servo conveying components can balance the allocation and control between the two sets of servo conveying components in the existing dual-servo discharging mechanism, avoiding the situation that the second servo conveying component has not completed the material reception after the first servo conveying component in the dual-servo discharging mechanism has completed the material discharge. The utility model adds a third group of servo conveying components, which can be used as a buffer conveying component. When the equipment is just started, the servo conveying component A receives the material. After the servo conveying component A receives the material, the servo conveying component B receives the material. At the same time, the servo conveying component C moves with the servo conveying component B. After the servo conveying component B completes the material reception, the servo conveying component A can be discharged. At this time, the servo conveying component B follows the servo conveying component A to move, and the servo conveying component C receives the material. When the servo conveying component A completes the discharging, the servo conveying component B discharges the material, and the servo conveying component A moves to the feeding end to follow the servo conveying component C to receive the material. This reciprocating process can achieve a large differential speed ratio between the packaging speed of the packaging machine and the feeding speed of the feeding conveyor belt. The added group of servo conveying components makes up for the alternation time between the servo conveying components from the feeding end to the discharging end, so that the two groups of servo conveying components can achieve uninterrupted connection between the feeding end and the discharging end, thereby adapting to a higher packaging speed, so as to solve the problems of unstable program control, failure to follow, missing packages, and wrong packages in the existing double servo discharging mechanism when the packaging speed is fast.

[0019] 2. The utility model further defines the motion coordination relationship among the servo conveying components A, B and C. Through the definition of this coordination relationship, the coordination relationship among the servo conveying components A, B and C is made simpler. They are arranged between the feeding tail frame of the packaging machine and the feeding conveyor belt to better balance the speed difference between the feeding tail frame of the packaging machine and the feeding conveyor belt, and realize material counting and sorting at the same time.

[0020] 3. In the utility model, the first transmission assembly, the second transmission assembly and the third transmission assembly are arranged according to the volume of the discharging mechanism, which is convenient for the installation and layout of the newly added third transmission assembly, and the structure is more compact and the equipment volume is small.

[0021] 4. The discharging mechanism of the utility model is applied to food packaging, and protective shields are set at both ends and the top to prevent food materials from being polluted by the external environment during the discharging process, ensuring food hygiene. At the same time, a pull-out slag receiving tray is set to prevent residues in the storage grid (such as oil and seasonings on food materials remaining on the storage grid) from directly dripping onto the workshop floor and causing pollution to the workshop, which is convenient for cleaning and further ensuring food hygiene.

[0022] 5. The discharging device of the utility model continuously feeds materials through the feeding conveyor belt, arranges the materials through the discharging mechanism, and pushes the materials from the storage grid of the discharging mechanism to the feeding tail rack of the packaging machine through the back-moving conveying mechanism for packaging. The structure is compact, and the discharging mechanism arranges and discharges the materials, while balancing the speed difference between the feeding tail rack of the packaging machine and the feeding conveyor belt, thereby realizing continuous supply, discharging arrangement and packaging of materials and improving material packaging efficiency.

DETAILED DESCRIPTION

[0030] The following are exemplary embodiments of the present invention that are combined with the accompanying drawings to help fully understand the claims and their equivalents, wherein the specific details are only considered as exemplary and do not limit the scope of the present invention. Therefore, those of ordinary skill in the art can make various changes and modifications to the embodiments without departing from the scope and spirit of the present invention.

[0031] As a preferred embodiment of the present invention, refer to the attached specification Figure 1 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the present embodiment discloses a discharging mechanism, which comprises a frame 1, one end of the frame 1 being a feed end 2, and the other end being a discharge end 3, the two ends of the frame 1 being respectively equipped with a first support shaft 4 and a second support shaft 5, the first support shaft 4 and the second support shaft 5 being respectively equipped with a first transmission assembly 6, a second transmission assembly 7 and a third transmission assembly 8, the first transmission assembly 6, the second transmission assembly 7 and the third transmission assembly 8 being respectively equipped with the first transmission assembly 6, a driven wheel and a transmission member, and a plurality of material storage grids 18 being respectively equipped with the transmission member; the frame 1 is also equipped with a first servo motor assembly 19, a second servo motor assembly 20 and a third servo motor assembly 21, wherein the first servo motor assembly 19 is connected in transmission with the first transmission assembly 6 to form a servo conveying assembly A, the second servo motor assembly 20 is connected in transmission with the second transmission assembly 7 to form a servo conveying assembly B, and the third servo motor is connected in transmission with the third transmission assembly 8 to form a servo conveying assembly C.

[0032] The existing dual-servo discharge mechanism is limited by the alternating interval of the dual servos, so that the conveying speed of the feed conveyor belt and the packaging speed are both limited by the alternating interval, and it is impossible to achieve full packaging speed or full feeding speed of the feed conveyor belt, thereby limiting the upper limit of the packaging speed of the packaging equipment.

[0033] The utility model adopts a three-servo discharging mechanism and adds a set of servo conveying components. The added servo conveying components can balance the allocation and control between the two sets of servo conveying components in the existing double-servo discharging mechanism, avoiding the situation where the second servo conveying component has not completed material reception after the first servo conveying component in the double-servo discharging mechanism has completed material discharge. A third group of servo conveying components is added, which can be used as a buffer conveying component. When the equipment is just started, the servo conveying component A receives the material. After the servo conveying component A receives the material, the servo conveying component B receives the material. At the same time, the servo conveying component C moves with the servo conveying component B. When the servo conveying component B completes the material reception, the servo conveying component A can be discharged. At this time, the servo conveying component B moves with the servo conveying component A, and the servo conveying component C receives the material. When the servo conveying component A completes the discharge, the servo conveying component B discharges the material, and the servo conveying component A moves to the feed end 2 to follow the servo conveying component C to receive the material. This reciprocating process can achieve a large differential speed ratio between the packaging speed of the packaging machine and the feeding speed of the feeding conveyor belt to solve the problems of unstable program control, failure to follow, missing packages, and wrong packages in the existing dual servo discharge mechanism when the packaging speed is fast.

[0034] As an example of the present utility model, the first support shaft 4 and the second support shaft 5 are both fixedly mounted on the frame 1, and the driving wheels (the first driving wheel 9, the second driving wheel 10 and the third driving wheel 11) and the driven wheels (the first driven wheel 12, the second driven wheel 13 and the third driven wheel 14) of the first transmission assembly 6, the second transmission assembly 7 and the third transmission assembly 8 are relatively rotatably mounted on the first support shaft 4 and the second support shaft 5; the transmission members (the first transmission member 15, the second transmission member 16 and the third transmission member 17) are connected to the driving wheels (the first driving wheel 9, the second driving wheel 10 and the third driving wheel 11) and the driven wheels (the first driven wheel 12, the second driven wheel 13 and the third driven wheel 14). At this time, the first servo motor assembly 19, the second servo motor assembly 20 and the third servo motor assembly 21 are respectively connected to the first driving wheel 9, the second driving wheel 10 and the third driving wheel 11, thereby driving the first transmission assembly 6, the second transmission assembly 7 and the third transmission assembly 8 to rotate. The assembly of the first driving wheel 9, the second driving wheel 10 and the third driving wheel 11 on the first supporting shaft 4 or the second supporting shaft 5 is determined according to the actual assembly space.

[0035] As another example of the present utility model, the first support shaft 4 and the second support shaft 5 both rotate relative to the frame 1. At this time, the first support shaft 4 and the second support shaft 5 can serve as transmission components of any two of the first transmission assembly 6, the second transmission assembly 7 and the third transmission assembly 8 to realize power transmission between the servo motor assembly and the transmission assembly.

[0036] As a preferred technical solution of the utility model, the first driving wheel 9 of the first transmission assembly 6 is fixedly connected to the first support shaft 4, the first driven wheel 12 of the first transmission assembly 6 is relatively rotatably mounted on the second support shaft 5, and the first servo motor drives the first support shaft 4 to rotate through the transmission belt. The second driving wheel 10 of the second transmission assembly 7 is fixedly connected to the second support shaft 5, the second driven wheel 13 of the second transmission assembly 7 is relatively rotatably mounted on the first support shaft 4, and the second servo motor drives the second support shaft 5 to rotate through the transmission belt. The third driving wheel 11 of the third transmission assembly 8 is relatively rotatably mounted on the second support shaft 5, the third driven wheel 14 of the second transmission assembly 7 is relatively rotatably mounted on the first support shaft 4, a transmission wheel is fixed on one side of the third driving wheel 11 of the third transmission assembly 8, and the third servo motor assembly 21 drives the third driving wheel 11 of the third transmission assembly 8 to rotate through the transmission belt. In this embodiment, the first transmission assembly 6, the second transmission assembly 7 and the third transmission assembly 8 are arranged according to the volume of the discharge mechanism, which is convenient for the installation and layout of the newly added third transmission assembly 8, and the structure is more compact and the equipment volume is small.

[0037] As another example of this embodiment, the driving wheel and the driven wheel may be sprockets or synchronous pulleys, and the transmission member may be a chain or a synchronous belt.

[0038] As a preferred technical solution of the utility model, in order to better realize the material discharging and conveying coordination of the three groups of servo conveying components, the servo conveying component A, the servo conveying component B and the servo conveying component C are configured as follows: when the servo conveying component A drives the several material storage grids 18 assembled thereon and completed material storage to move to the discharging end 3 for counting and discharging one by one, the servo conveying component B drives the several material storage grids 18 assembled thereon to move to the feeding end 2 for storing material one by one, and after reaching the set quantity requirement, it quickly moves to the tail end of the material storage grid 18 on the servo conveying component A and follows the movement of the servo conveying component A; at this time, the servo conveying component C drives the several material storage grids 18 assembled thereon to move to the feeding end 2 for storing material one by one; when the servo conveying component A completes the material discharging at the discharging end 3, the servo conveying component B drives the several material storage grids 18 assembled thereon to move to the feeding end 2 for storing material one by one. After the material is discharged, the servo conveying component B continues to discharge at the discharge end 3, and the servo conveying component A quickly moves to the tail end of the material storage grid 18 on the servo conveying component C and follows the movement of the servo conveying component C; after the servo conveying component C completes the material storage, it quickly moves to the tail end of the material storage grid 18 on the servo conveying component B and follows the movement of the servo conveying component B; after the servo conveying component B completes the material discharge at the discharge end 3, the servo conveying component C continues to discharge at the discharge end 3, and the servo conveying component B quickly moves to the tail end of the material storage grid 18 on the servo conveying component A and follows the movement of the servo conveying component A; after the servo conveying component A completes the material storage, it quickly moves to the tail end of the material storage grid 18 on the servo conveying component C and follows the movement of the servo conveying component C; repeat the above process for continuous discharge.

[0039] For example: when the packaging speed of the packaging machine is 200 packs / min, if the existing dual-servo discharge mechanism is used, after the previous servo conveying component completes the discharge of the last storage grid 18, the time left for the next servo conveying component to move to the discharge end 3 and complete the discharge is only 0.3s. This time is not enough for the next servo conveying component to complete the action of moving from the feed end 2 to the discharge end 3 and outputting the material of the first storage grid 18. Therefore, the uninterrupted connection between the previous servo conveying component and the next servo conveying component cannot be achieved, which will cause leakage of packages. By adopting the configuration mode of the servo conveying component A, the servo conveying component B and the servo conveying component C of the utility model, when the servo conveying component A is discharging materials, the servo conveying component B completes the material connection and is connected behind the servo conveying component A and moves with it, so that the servo conveying component A and the servo conveying component B are connected together uninterruptedly, which can fully meet the high-speed packaging requirements. When the servo conveying component A completes the material discharging, the servo conveying component A moves to the back of the servo conveying component C and moves with it, so as to realize the uninterrupted material connection between the servo conveying component C and the servo conveying component A, so as to meet the higher feeding speed of the feeding conveyor belt.

[0040] A tensioning wheel 22 for tensioning transmission members in the first transmission assembly 6 , the second transmission assembly 7 and the third transmission assembly 8 is arranged between the first support shaft 4 and the second support shaft 5 .

[0041] As another embodiment of the present invention, it is further preferred that a pull-out slag receiving pan 26 is provided below the servo conveying assembly A, the servo conveying assembly B and the servo conveying assembly C assembled on the frame 1 .

[0042] As an implementation method of the present utility model, refer to the attached specification Figure 1 and attached Figure 2 As shown, a first shield 23 and a second shield 24 are provided at both ends of the frame 1 for respectively covering the first support shaft 4 and the second support shaft 5, and the first shield 23 and the second shield 24 are connected to the frame 1 by hinges. Furthermore, a third shield 25 is provided above the frame 1, and the third shield 25 is connected to the frame 1 by hinges. The discharging mechanism of the utility model is applied to the field of food packaging, and shields are provided at both ends and the top to prevent food materials from being contaminated by the external environment during the discharging process, thereby ensuring food hygiene. At the same time, a pull-out slag receiving tray 26 is provided to prevent residues in the storage grid 18 (such as residues of oil, seasonings, etc. on the food materials remaining on the storage grid 18) from directly dripping onto the workshop floor and causing pollution to the workshop, thereby facilitating cleaning and further ensuring food hygiene.

[0043] As another embodiment of the utility model, this embodiment discloses a discharge conveying device, including the above-mentioned discharge mechanism, and also including a feed conveyor belt (not shown in the figure) and a back-wash conveying mechanism 27, the output end of the feed conveyor belt is connected to the feed end 2 of the discharge mechanism, and the material on the feed conveyor belt is conveyed to the storage grid 18 on the discharge mechanism; the back-wash conveying mechanism 27 is arranged above the discharge end 3 of the discharge mechanism, and is configured to push the material in the storage grid 18 located at the discharge end 3 of the discharge mechanism out of the storage grid 18.

[0044] While the inventive concept has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made thereto without departing from the spirit and scope of the invention as defined in the claims.
