Description

TECHNICAL FIELD

[0001] The utility model belongs to tobacco equipment technical field, concretely relates to a multifunctional cap screwing machine. BACKGROUND

[0002] The automatic equipment line for tobacco production needs to pre-mix and stir sugar flavoring for tobacco, and different sugar flavorings are stored in barrels. Before pouring the sugar flavoring in the barrel into the stirring tank, the barrel cover on the barrel needs to be opened manually, and then other equipment clamps the barrel to pour the sugar flavoring in the barrel into the stirring tank. After completing the pouring work, the barrel is recycled and the barrel cover is re-covered on the barrel for repeated use of the barrel.

[0003] However, the manual operation to open / close the barrel undoubtedly increases labor cost, and the process of pouring the barrel into the stirring tank is relatively long (the sugar flavoring is viscous, the flow speed is slow, and the pouring time is long), which delays the interval time of pouring different barrels and reduces the utilization rate of manual operation. INVENTION CONTENTS

[0011] Further, the cap screwing assembly comprises a sliding table, a lifting table and a cap screwing mechanism.

[0012] The sliding table is established on the workbench plate, and the sliding rail of the sliding table is vertically arranged with the barrel cover conveying belt.

[0013] The lifting table is established on the sliding table.

[0014] A rotating arm is provided on the lifting platform, and a rotating gripper is provided at the bottom of the rotating arm. The rotating gripper is adapted to the barrel lid. The beneficial effect of this step is that the capping assembly can realize horizontal and vertical movement, loosen and remove the barrel lid from the material barrel, temporarily place it on the barrel lid conveyor belt, and after the empty barrel is placed on the material barrel placement platform, take the barrel lid out from the barrel lid conveyor belt and tighten it on the material barrel.

[0015] Furthermore: the lid conveyor belt is provided with several equally spaced lid limiting blocks, and the lid conveyor belt is driven by a stepper motor.

[0041] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0042] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0043] Examples of embodiments of this utility model Figures 1-5 As shown, the present invention provides a multi-functional capping machine to replace manual capping of material barrels, thereby reducing labor costs and improving the automation level of the equipment.

[0044] This utility model includes: a frame 1;

[0045] The workbench 2 is located on the top surface of the frame 1;

[0046] At least one capping assembly 3 is provided on the top surface of the worktable 2;

[0047] The bucket lid conveyor belt 4 is located on the bottom surface of the workbench 2 and corresponds to the position of the capping assembly 3;

[0048] At least one bucket placement platform 5 is adjacent to the frame 1 and the bucket lid conveyor belt 4, and is located within the range of motion of the capping assembly 3.

[0049] This utility model utilizes the material bucket placement platform 5 to place and fix the material bucket, and works with the capping assembly 3 to open and close the lid 61 on the material bucket 6, which can replace manual operation and save labor costs.

[0050] In one embodiment, the screw cap assembly 3 includes:

[0051] The sliding table 31 is provided on the worktable 2, and the slide rail of the sliding table 31 is perpendicular to the barrel lid conveyor belt 4, which can ensure that the sliding table 31 meets the requirements of the corresponding material barrel 6 and the barrel lid conveyor belt 4 at the minimum displacement stroke. The sliding table 31 can be driven by a cylinder.

[0052] The lifting platform 32 is mounted on the sliding platform 31 and can move via a lead screw.

[0053] A rotating arm 33 is mounted on the lifting platform 32, and a rotating gripper is provided at the bottom of the rotating arm 33. The rotating gripper is adapted to the barrel lid 61. The lid screwing assembly 3 can move horizontally and vertically to loosen and remove the barrel lid 61 from the material barrel 6 and temporarily place it on the barrel lid conveyor belt 4. After the empty barrel is placed on the material barrel placement platform 5, the barrel lid 61 is taken out from the barrel lid conveyor belt 4 and screwed onto the material barrel 6.

[0054] In one embodiment, the lid conveyor belt 4 is provided with a plurality of equidistant lid limiting blocks 41. Each lid limiting block 41 is composed of two symmetrical limiting blocks. The lid conveyor belt 4 is driven by a stepper motor. The stroke of the stepper motor driving the lid conveyor belt 4 in a single rotation is the same as the distance between two adjacent lid limiting blocks 41. This ensures the accuracy of the capping assembly 3 in picking up and placing the lid 61. The lid limiting blocks 41 can prevent the capping assembly 3 from shifting its position when placing the lid 61 on the lid conveyor belt 4, so as to ensure that the capping assembly 3 does not miss the lid 61 when it picks it up again from the lid conveyor belt 4.

[0055] In one embodiment, when there are two capping assemblies 3, the two capping assemblies 3 are arranged mirror images of each other on the top surface of the worktable 2;

[0056] The number and position of the material bucket placement platform 5 correspond to the capping assembly 3. Increasing the number of capping assemblies 3 can improve work efficiency.

[0057] In one embodiment, a plurality of photoelectric sensors 42 are provided on one side of the lid conveyor belt 4, respectively located at the head end, tail end and corresponding positions of the two capping assemblies 3.

[0058] Furthermore, there are n lid limiting blocks 41 between the two capping assemblies 3. A photoelectric sensor 42 is also provided at a position n times the distance between the photoelectric sensor 42 at the beginning of the lid conveyor belt 4 and the photoelectric sensor 42 at the end of the lid conveyor belt 4. When the capping assembly 3 places lids 61 onto the lid conveyor belt 4, it is necessary to prevent excessive lids 61 from being placed on the lid conveyor belt 4, causing blockage. The photoelectric sensor 42 is used to detect whether there are lids 61 on the lid conveyor belt 4. Specifically, if there are 14 lid limiting blocks 41 on the top surface of the lid conveyor belt 4, 14 lids 61 can be placed. When the two capping assemblies 3 are located at the center of the lid conveyor belt 4, and there are 6 lid limiting blocks 41 between the two capping assemblies 3, the 14 lid limiting blocks 41 are numbered n1 from left to right. When the lid conveyor belt 4 rotates from right to left and there are no lids 61 on the conveyor belt 4 initially, the two capping assemblies 3 will place lids 61 at positions n4 and n11 respectively. As the stepper motor drives, n4 becomes n3, n11 becomes n10, and lids are continuously added. The photoelectric sensor 42 at n1 will detect lids 61. The initial n11 becomes n8, and the photoelectric sensor 42 at n8 will detect lids 61. When both photoelectric sensors 42 detect lids 61 at the same time, it means that the lid conveyor belt 4 rotating to the left is full of lids 61 and no more lids 61 can be added. The lids 61 need to be screwed onto empty buckets. Conversely, when the lid conveyor belt 4 rotates to the right, when the photoelectric sensors 42 at positions n7 and n14 detect lids 61 at the same time, it means that the lids 61 are also full. The photoelectric sensor 42 corresponding to the capping assembly 3 detects whether there are lids 61 at the corresponding positions.

[0059] In one embodiment, the material bin placement platform 5 includes:

[0060] Mounting bracket 51;

[0061] Motor 52 is disposed on the bottom surface of the mounting bracket 51, and the output shaft of motor 52 extends out of the mounting bracket 51;

[0062] Turntable 53, the center of the bottom surface of turntable 53 is connected to the output shaft;

[0063] A limiting structure 54 is provided on the top surface of the turntable 53. The limiting structure 54 is adapted to the material bucket 6. When the material bucket 6 is placed on the turntable 53, its position may be deflected and not correspond to the capping assembly 3. At this time, it is necessary to adjust the posture of the material bucket 6 through the turntable 53. Generally, if the material bucket 6 is square, it may be deflected by 90°, 180° or 270°. If it is rectangular, it may be deflected by 180°. The angle of rotation of the turntable 53 driven by the motor 52 can be manually controlled or automatically controlled by devices such as angle encoders.

[0064] In one embodiment, the top surface of the mounting bracket 51 is centered on the output shaft and has a plurality of universal balls 55 evenly distributed in a ring. The top edge of the universal balls 55 abuts against the bottom surface of the turntable 53. Since the material bucket 6 contains liquid, it will inevitably shake during transportation. Under the long-term kinetic energy generated by the shaking, the output shaft may bend or the connection between the turntable 53 and the output shaft may become loose, causing the material bucket 6 to be unable to be placed stably on the turntable 53. Therefore, it is necessary to use the universal balls 55 to abut against the turntable 53 to ensure that the turntable 53 rotates smoothly.

[0065] In one embodiment, the limiting structure 54 is composed of several limiting plates 541. The lower edge of the limiting plate 541 is provided with a horizontally bent fixing plate 543. The fixing plate 543 is connected to the turntable 53. The limiting plate 541 ensures that the material bucket 6 can accurately fall on the turntable 53.

[0066] Based on the above technical solution, the upper edge of the limiting plate 541 is provided with an outwardly bent guide plate 542, through which the material barrel 6 is guided into the limiting structure 54.

[0067] Based on the above technical solutions, the included angle between the limiting plate 541 and the fixing plate 543 is 90°. This structure is a direct limiting structure, allowing the limiting plate 541 to fit against the material bucket 6. However, it can only be applied to material buckets 6 of the same size. Alternatively, the limiting plate 541 can be tilted towards the center of the turntable 53, with the tilt angle ranging from 0° to 15°. This structure is an elastic limiting structure, utilizing the elasticity of the limiting plate 541 to allow the connection between the limiting plate 541 and the guide plate 542 to abut against the side wall of the material bucket 6. This structure can be suitable for material buckets 6 of various sizes. Both limiting structures can effectively limit the material bucket 6 from deflecting as the bucket lid 61 is subjected to force.

[0068] In the above embodiments, the present invention uses rotating grippers to open or tighten the lid 61, and then uses the sliding table 31 and lifting table 32 to send the lid 61 to the corresponding position. It should be noted that the stepping speed of the lid conveyor belt 4 conveying the lid 61 needs to be matched with the lid screwing assembly 3 so that the lid 61 can be automatically opened and tightened through the above components.

[0069] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details.
