Description

Technical Field

[0001] This utility model belongs to the technical field of thermos cup production equipment, and relates to an automatic thermos cup spout dispensing machine. Background Technology

[0002] A thermos flask is a common insulated container used in daily life. It mainly consists of an inner liner and an outer shell. The inner liner and outer shell are insulated by a vacuum to slow down the heat loss from the inside of the inner liner. The inner liner and outer shell are usually made of stainless steel through welding and water expansion molding. After the inner liner and outer shell are formed, the inner liner is first inserted into the outer shell, aligning the mouths of the inner liner and the outer shell and forming a tight fit through pressure, which is the fitting process. Then, the mouth of the cup is welded to make the mouth of the inner liner and the mouth of the outer shell a whole, so as to ensure a seal between the inner liner and the outer shell.

[0003] Currently, the spouting of insulated cups is mainly done manually or with automated equipment. However, due to low efficiency, high cost, and poor quality stability, manual spouting is gradually being replaced by automated equipment. For example, Chinese patent application (application number: 202323614030.5) discloses a multi-station insulated cup spouting machine, which includes a machine body comprising an upper frame and a lower frame. The upper frame has a pressing component and a spouting component, connected to the lower end of the pressing component. The pressing component can drive the spouting component to move up and down. The spouting component includes a cylinder and a spouting plate, with the spouting plate located at the lower end of the cylinder. The cylinder can drive the spouting plate to move up and down. The lower frame has a turntable and a driving component, which can drive the turntable to rotate. The turntable has several mounting seats; when the turntable rotates, the mounting seats rotate to the lower end of the spouting plate. However, because this solution uses a turntable for feeding, the loading and unloading of thermos cups are done at the same station, i.e., loading and unloading are done at the front of the equipment. This results in a longer loading and unloading time. Furthermore, this solution does not have a loading and unloading mechanism, so the continuity and efficiency of the work are still relatively poor. It is more suitable for manual loading and unloading and is not easy to cooperate with the production line. The degree of automation is still relatively low. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an automatic thermos cup dispensing machine. The technical problem to be solved by this utility model is: how to improve the automation level of the automatic thermos cup dispensing machine.

[0005] The purpose of this utility model can be achieved through the following technical solution: An automatic thermos cup dispensing machine, comprising: a frame, the frame having a worktable, and the worktable having a first placement table and a second placement table for placing thermos cups spaced apart along the direction from the front to the rear.

[0006] The pressing mechanism includes a pressure plate located above the first placement platform and a drive component for driving the pressure plate to move up and down.

[0007] The feeding assembly has a first gripper and a second gripper that are arranged in front of and behind and move synchronously. The first gripper is used to pick up the thermos cup on the front side of the workbench and place it on the first placement table, and the second gripper is used to pick up the thermos cup on the first placement table and place it on the second placement table.

[0008] This invention can be directly installed in an automated production line for thermos cups. The production line at the front of the frame conveys thermos cups with the inner liner and outer shell initially fitted but not yet tightly pressed to the front of the workbench. The rear of the frame can be connected to the production line for subsequent processing steps of the thermos cups. The first gripper of the feeding assembly picks up the thermos cups at the front and places them on the first placement table for fitting. At the same time, the second gripper picks up the thermos cups on the first placement table that have been fitted and places them on the second placement table, so that they can be conveyed to the production line at the rear of the frame, thus realizing fully automated production.

[0009] In the aforementioned automatic thermos cup dispensing machine, the feeding assembly includes a gripper mechanism, a lifting mechanism, and a translation mechanism. The first and second grippers are both located on the gripper mechanism. The lifting mechanism drives the gripper mechanism to move up and down, and the translation mechanism drives the gripper mechanism to reciprocate along the direction from the first placement platform to the second placement platform. Thus, through the cooperation of the gripper mechanism, the lifting mechanism, and the translation mechanism, the thermos cup can be first clamped and fixed, then moved upwards to a certain height, then moved above the target position, and finally lowered and placed on the target position, thereby realizing the transfer of the thermos cup.

[0010] In the above-mentioned automatic thermos cup dispensing machine, a mounting plate is fixed on the frame, and several vertically arranged guide columns are fixed on the mounting plate. The lifting mechanism includes a lifting platform and a second driving component. The lifting platform is slidably connected to the guide columns, and the second driving component is fixed relative to the mounting plate and used to drive the lifting platform to move up and down.

[0011] In the above-mentioned automatic thermos cup dispensing machine, the translation mechanism includes a first slide rail fixed on the lifting platform, a translation slide table that slides with the first slide rail, and a translation drive mechanism for driving the translation slide table to reciprocate along the first slide rail. The first slide rail is arranged along the direction from the first placement platform to the second placement platform.

[0012] In the aforementioned automatic thermos cup dispensing machine, the translation drive mechanism includes a drive motor and a lead screw drive pair that is connected to the drive motor.

[0013] In the aforementioned automatic thermos cup dispensing machine, the drive motor is fixed to the lower side of the lifting platform, and the mounting plate has a clearance groove for the drive motor. The clearance groove allows the drive motor to be inserted into the groove when the lifting platform moves downwards, preventing interference with the mounting plate. This allows the lifting platform and mounting plate to be closer together, resulting in a more compact overall lifting mechanism that occupies less space.

[0014] In the above-mentioned automatic thermos cup spouting machine, the gripper mechanism includes a second slide rail, a third driving component, two slide blocks, and the first and second grippers. The second slide rail is laterally arranged on the translation slide table, and the two slide blocks are slidably arranged on the second slide rail. The third driving component is used to drive the two slide blocks to move closer or further away from each other along the second slide rail. The first and second grippers are fixed on the two slide blocks and are located on both sides of the two slide blocks respectively.

[0015] In the aforementioned automatic thermos cup dispensing machine, the third driving component is a finger slide cylinder.

[0016] In the aforementioned automatic thermos cup spout dispenser, the first placement platform, the second placement platform, the pressing mechanism, and the gripper mechanism are all arranged in two parallel rows.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This utility model uses a feeding assembly with double grippers at the front and rear to linearly transport insulated cups, making it easy to adapt to automated production lines for insulated cups. It can connect to a production line that transports insulated cups with pre-fitted inner liner and outer shell on its front side, and to a subsequent production line on its rear side. The insulated cups pre-fitted on the front side are sequentially transported in a straight line to the first placement table for assembly, and then the insulated cups after assembly are moved to the second placement table on the rear side of the frame for transport to the subsequent production line. The whole process is smoother and more automated.

[0019] 2. The feeding assembly of this utility model can simultaneously transfer the thermos cups with their mouths already fitted on the first placement table to the second placement table when the pre-fitted thermos cups on the front side of the frame are transferred to the first placement table, making the work efficiency of this utility model higher and the rhythm smoother.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] An automatic thermos cup spout dispenser, such as Figure 1 , Figure 2 As shown, the device includes a frame 1, a pressing mechanism 3, and a feeding assembly. The frame 1 has a worktable 11, on which a first placement platform 12 and a second placement platform 13 are spaced apart from the front to the rear. The pressing mechanism 3 includes a pressure plate 31 and a driving component 32 for driving the pressure plate 31 to move up and down. The pressure plate 31 is located directly above the first placement platform 12. Under the action of the driving component 32, the pressure plate 31 can press down the thermos cups on the first placement platform 12, where the inner liner and outer shell are pre-fitted, to complete the fitting of the inner liner and the outer shell. The feeding assembly is set on the frame 1 and can move the thermos cups on the front side of the worktable 11 in a straight line to the first placement platform 12, and simultaneously move the thermos cups on the first placement platform 12 to the second placement platform 13. This invention allows the front side of the workbench 11 to be connected to a production line for conveying pre-fitted thermos cups with inner liner and outer shell, and the rear side of the workbench to be connected to a production line for subsequent processing steps. This enables the invention to transfer the pre-fitted thermos cups on the front side of the workbench 11 to the first placement table 12 for splicing, and then transfer the spliced ​​thermos cups to the second placement table 13 for conveying to the production line on the rear side of the workbench for subsequent processing.

[0029] Specifically, such as Figures 2-5As shown, a horizontally mounted mounting plate 14 is fixed on the frame 1. The mounting plate 14 is square and located below the workbench 11. Four guide posts 15 are vertically mounted on the mounting plate 14, located at the four corners of the mounting plate 14. The feeding assembly on the mounting plate 14 includes a gripper mechanism 6 for holding the thermos cup, a lifting mechanism 4 for driving the gripper mechanism 6 to move up and down, and a translation mechanism 5 for driving the gripper mechanism 6 to move forward and backward. The lifting mechanism 4 includes a lifting platform 41 and a driving component 42. The lifting platform 41 is also square and has four guide posts. 15 is slidably connected above the mounting plate 14. In this embodiment, the second driving component 42 is a cylinder. The second driving component 42 is fixed on the mounting plate 14 and connected to the lifting platform 41, so that the second driving component 42 can drive the lifting platform 41 to move up and down along the guide column 15. The translation mechanism 5 includes a first slide rail 51, a translation slide 52, and a translation driving mechanism. In this embodiment, there are two first slide rails 51 spaced apart. Both first slide rails 51 are fixed on the lifting platform 41 along the direction from the first placement platform 12 to the second placement platform 13. The translation slide 52 communicates with the two first slide rails 51. The sliding connection via the slider includes a drive motor 53 and a lead screw drive pair. The drive motor 53 is fixed to the rear side of the lifting platform 41 and is connected to the lead screw drive pair. The lead screw drive pair is arranged along the length direction of the first slide rail 51 and is connected to the translation slide 52, so that the drive motor 53 can drive the translation slide 52 to reciprocate along the length direction of the first slide rail 51. The gripper mechanism 6 includes a second slide rail 61, a drive component 62, two slide blocks 63, a first gripper 64, and a second gripper 65. The second slide rail 61 is laterally fixed on the translation slide 52, and both slide blocks 63 are hung on... The slide block 63 is set on the second slide rail 61, and the upper end of the slide block 63 extends out of the worktable surface 11 and is located on both sides of the first placement table 12. The two claw parts of the first claw 64 and the second claw 65 are respectively arranged on both sides of the upper end of the two slide blocks 63 along the direction from the first placement table 12 to the second placement table 13. In this embodiment, the driving component 62 is a finger slide cylinder. The driving component 62 is fixed on the translation slide table 52 and is connected to the two slide blocks 63 respectively, so that the driving component 62 can drive the two slide blocks 63 and the two claw parts of the first claw 64 and the second claw 65 to move closer or further away from each other. Furthermore, in this embodiment, the distance between the clamping positions of the first gripper 64 and the second gripper 65 is the same as the distance between the first placement platform 12 and the second placement platform 13. This allows the feeding assembly, through the cooperation of the lifting mechanism 4, the translation mechanism 5, and the gripper mechanism 6, to move the thermos cup on the front side of the workbench 11 to the first placement platform 12 by clamping, moving upward, translating, falling, and releasing, while the second gripper 65 simultaneously moves the thermos cup on the first placement platform 12 to the second placement platform 13.

[0030] Furthermore, in this embodiment, the drive motor 53 is fixed to the rear lower side of the lifting platform 41, and the mounting plate 14 has a clearance groove 14a for avoiding the drive motor 53. The clearance groove 14a is located directly below the drive motor 53, so that after the lifting platform 41 is lowered, the drive motor 53 can be embedded in the clearance groove 14a, and the lifting platform 41 and the mounting plate 14 can be closer together, making the structure of the feeding assembly more compact.

[0031] like Figure 2 , Figure 6 As shown, a mounting frame 2 is provided on the frame 1. The mounting frame 2 includes two uprights 21, a fixed crossbeam 22, and a movable crossbeam 23. The two uprights 21 are fixed on the frame 1 and located on both sides of the workbench 11. The two ends of the fixed crossbeam 22 are fixedly connected to the two uprights 21 and located above the first placement platform 12. The movable crossbeam 23 is movably connected to the two uprights 21 and located below the fixed crossbeam 22. The fixed crossbeam 22 and the movable crossbeam 23 are connected by a screw. In this embodiment, a pressing mechanism 3 is provided on the movable crossbeam 23, allowing the operator to adjust the height of the movable crossbeam 23 according to the size of the thermos cup. The pressing mechanism 3 includes a drive component 32 and a pressure plate 31. In this embodiment, the drive component 32 is a cylinder. The drive component 32 is vertically fixed on the movable crossbeam 23, and the piston rod of the drive component 32 is connected to the pressure plate 31, so that the pressure plate 31 is located directly above the first placement platform 12 and can be raised and lowered relative to the pressure plate 31.

[0032] Furthermore, in this embodiment, the first placement platform 12, the second placement platform 13, the pressing mechanism 3, and the gripper mechanism 6 are all arranged in pairs side by side, enabling them to simultaneously fit two thermos cups, thus improving work efficiency.
