Description

Technical Field

[0001] The invention relates to the field of catering supplies production equipment, and in particular to an automatic cup covering device. Background Art

[0002] At present, the automatic lidding of milk tea cups is done by taking the lid from the bottom, grabbing the lid with a robot, moving it to the top of the milk tea cup, and pressing the lid down tightly.

[0003] The existing robot automatically covers milk tea cups, but the machine equipment occupies a large space and is expensive, making it difficult for customers to accept such equipment. At the same time, there is currently no single machine suitable for mobile production line for cup covering machines. In the existing cup covering machines, more than 30 cup covers are stacked and placed in a cylinder. There is a screw in the cylinder that pushes the entire cup cover up after each cup cover is used. The upper structure of the equipment grabs the cup cover at a high place, and then the robot grabs the milk tea cup and places it directly below the cup cover, and the upper mechanism presses the cup cover down on the milk tea cup.

[0004] The existing automatic milk tea cup cover machine has the following problems:

[0005] 1. The cup lid can only be placed directly below the cup cover;

[0006] 2. Use a robot to move the milk tea cups from other places to the lid cup;

[0007] 3. The equipment needs to be equipped with a robot, and the chassis cabinet used by the robot is relatively large;

[0008] 4. After the device has used up the milk tea cup lid, it is troublesome to add the cup lid again. Summary of the invention

[0009] The invention provides an automatic cup covering device, aiming to solve the problem that the existing cup covering machine is large in size and needs to be equipped with a robot to assist in cup covering.

[0010] The present invention provides an automatic cup covering device, comprising a cup cover discharging mechanism for storing cup covers, a cup cover grabbing mechanism, and a cup cover claw rotating mechanism, wherein the cup cover grabbing mechanism is connected to the cup cover claw rotating mechanism, the cup cover discharging mechanism is arranged at a station above the cup cover grabbing mechanism, a station for placing a cup body is arranged below the cup cover grabbing mechanism, and the cup cover claw rotating mechanism drives the cup cover grabbing mechanism to move between an upper station and a lower station, and at the same time drives the cup cover grabbing mechanism to rotate so that the claw mouth switches between an upward state and a downward state.

[0011] As a further improvement of the present invention, the cup cover claw rotating mechanism includes a driving module, a rotating baffle with a vertical guide groove, a cup cover claw connecting rod, and a rotating rack. The rotating rack is located in the middle of the vertical guide groove and connected to the inner wall of the rotating baffle. One end of the cup cover claw connecting rod is connected to the cup cover grasping mechanism, and the other end thereof is provided with a connecting rod gear, and the connecting rod gear is meshed with the rotating rack. The driving module is connected to the cup cover claw connecting rod, and the driving module drives the cup cover claw connecting rod to move up and down in the vertical guide groove. When the cup cover claw connecting rod moves to the middle of the vertical guide groove, the connecting rod gear meshes with the rotating rack to move and rotate. The vertical guide groove provides space for the cup cover claw connecting rod to move between the upper and lower workstations. At the same time, the connecting rod gear is meshed with the rotating rack in the middle of the vertical guide groove, so that the cup cover claw connecting rod can synchronously drive the cup cover grasping mechanism to flip during the movement, and the movement and flipping actions are achieved in one step, which meets the requirements of the automated production process.

[0012] As a further improvement of the present invention, the cup cover claw rotating mechanism includes a rotating block, a steering wheel coupling, and a steering wheel that rolls in a vertical guide groove. One end of the rotating block is hinged to the cup cover claw connecting rod, and the other end is hinged to the steering wheel coupling. The steering wheel is connected to the steering wheel coupling. The steering wheel and the connecting rod gear are both located on the same side of the rotating block. A flip expansion groove is provided in the middle of the vertical guide groove. When the connecting rod gear is meshed and moved with the rotating rack, the rotating block flips along the flip expansion groove with the connecting rod gear as the center of the circle. The steering wheel is set to be responsible for the rotating block to move in the vertical guide groove. When the connecting rod gear is not meshed with the rotating rack, it is driven to move by the steering wheel. The connecting rod gear is responsible for meshing with the rotating rack to realize the flipping of the claw mouth direction of the cup cover grabbing mechanism. At the same time, the entire rotating block will also flip, and the flip expansion groove provides enough space for the flipping of the rotating block.

[0013] As a further improvement of the present invention, the driving module includes a linkage plate, the linkage plate is provided with a connecting rod hole, the cup cover claw connecting rod passes through the connecting rod hole and is connected to the linkage plate, the rotating baffle is provided with a linkage guide groove, the linkage guide groove is parallel to the vertical guide groove, the cup cover claw rotating mechanism includes a linkage rod, the linkage rod is connected to the linkage plate and is located in the linkage guide groove, a rotating connecting rod is provided in the middle of the rotating block, and the linkage rod is connected to the rotating connecting rod through a spring.

[0014] As a further improvement of the present invention, the cup cover claw rotation mechanism includes a limit plate, the limit plate is connected to the linkage plate and is located in the linkage guide groove, the limit plate extends to the side of the rotating block and limits the rotating block, and the limit surface of the limit plate is parallel to the vertical guide groove. The limit plate can prevent the rotating block from deviating from the vertical guide groove when moving or rotating, and also prevents the rotating block from excessively deviating from the linkage guide groove under the action of the elastic force.

[0015] As a further improvement of the present invention, the driving module includes a driving motor and a screw rod, the screw rod is vertically distributed and connected with the linkage plate, and the driving motor is connected with the screw rod and drives it to rotate. The driving motor and the screw rod cooperate as a driving mode, and the structure arranged up and down saves space for the whole machine. The cooperation between the screw rod and the linkage plate can also ensure smooth and stable movement.

[0016] As a further improvement of the present invention, the driving module includes a guide rail column and a linear bearing. The guide rail column is vertically distributed and located at both ends of the linkage plate. The guide rail column is connected to the through hole of the linkage plate through the linear bearing. The guide rail column assists the up and down movement of the linkage plate, ensuring that the linkage plate moves stably under the drive of the screw rod, avoiding the problem of vibration or deviation from the movement trajectory during the movement of the linkage plate.

[0017] As a further improvement of the present invention, the automatic cup cover device includes a cup gripping mechanism, which is located at a lower station of the cup cover gripping mechanism, and includes a left cup claw, a right cup claw, a cup gripping slide rail, a cup gripping gear, and a cup gripping motor.

The cup gripping motor only needs to drive the cup gripping gear to realize the synchronous opening and closing of the left cup claw and the right cup claw through the meshing of the left rack and the right rack. The structure is simple and the installation is convenient, and the automatic operation of the cup gripping action is realized at the same time.

[0018] As a further improvement of the present invention, the cup grabbing mechanism includes a left stop column and a right stop column, which are respectively connected to the two ends of the track of the cup grabbing slide rail and limit the sliding range of the left claw transmission plate and the right claw transmission plate. The left stop column and the right stop column limit the moving range of the left cup claw and the right cup claw within a certain range, thereby preventing the left cup claw and the right cup claw from excessively clamping the cup body when they are closed, and also preventing the left rack and the right rack from being separated from the cup grabbing gear when the left cup claw and the right cup claw are excessively opened.

[0029] The cup cover claw rotating mechanism 1 includes a driving module, a rotating baffle 11 provided with a vertical guide groove 12, a cup cover claw connecting rod 13, and a rotating rack 14. The rotating rack 14 is located in the middle of the vertical guide groove 12 and is connected to the inner wall of the rotating baffle 11. One end of the cup cover claw connecting rod 13 is connected to the cup cover grasping mechanism 2, and the other end thereof is provided with a connecting rod gear 15. The connecting rod gear 15 is meshed with the rotating rack 14. The driving module is connected to the cup cover claw connecting rod 13, and the driving module drives the cup cover claw connecting rod 13 to move up and down in the vertical guide groove 12. When the cup cover claw connecting rod 13 moves to the middle of the vertical guide groove 12, the connecting rod gear 15 meshes with the rotating rack 14 to move and rotate.

[0030] The cup cover claw rotating mechanism 1 includes a rotating block 16, a steering wheel coupling, and a steering wheel 17 that rolls in a vertical guide groove. One end of the rotating block is hinged to the cup cover claw connecting rod 13, and the other end is hinged to the steering wheel coupling. The steering wheel 17 is connected to the steering wheel coupling. The steering wheel 17 and the connecting rod gear 15 are both located on the same side of the rotating block 16. A flip expansion groove 121 is provided in the middle of the vertical guide groove 12. When the connecting rod gear 15 and the rotating rack 14 are meshed and moved, the rotating block 16 flips along the flip expansion groove 121 with the connecting rod gear 15 as the center of the circle.
