Description

Technical Field

[0001] The utility model relates to the technical field of feeding of auxiliary materials for tobacco packaging machines, and more specifically, to a double-row buffer device. Background Art

[0002] Generally, the label paper of the client is usually stored on a pallet in the warehouse after being packaged. Workers use a hydraulic truck or an AGV (Automated Guided Vehicle) to transport the label paper from the warehouse to a designated position in the workshop. Then, a collaborative robot orderly picks up the label paper on the input belt of the cutting machine according to the on-site working conditions. Next, the kraft paper wrapped around the label paper is removed by the cutting machine, and then the label paper is conveyed to the output belt of the cutting machine for the main machine to use. After the label paper on the pallet is used up, the empty pallet needs to be removed. Then, the materials are transported to the designated position by workers or AGVs again, repeating the feeding process.

[0003] When the label paper on the pallet is used up, workers or AGVs are needed again to transport the materials to the designated position. If workers transport the materials, several workers need to be specifically assigned to transport the label paper for the entire factory area. Some machines are relatively far from the warehouse, and it takes a certain amount of time for a round trip to transport the label paper, resulting in high labor intensity, large physical consumption, and low automation, thus leading to low work efficiency. At present, due to the upgrade of packaging equipment and the widespread application of high-speed machines, the label paper remaining on the cutting machine can no longer meet the production requirements. When the label paper is transported to the designated position, the main machine will largely stop running, resulting in production suspension.

[0004] If an AGV is used to transport the materials, generally one AGV supplies materials to multiple devices. When an AGV transports label paper to device A, device B also issues a material request call instruction at the same time. At this time, the AGV will give priority to supplying materials to device A according to the first-in, first-out principle, and device B can only wait. After the AGV finishes feeding device A, the AGV goes to the warehouse to pick up materials and transport them to device B. Due to the long waiting time and long cycle of material delivery, plus the label paper remaining on the cutting machine is only enough for a few minutes of consumption. By the time the AGV transports the label paper from the warehouse to device B, the main machine has already stopped running, cannot produce, and greatly reduces the production efficiency. To resume production, the machine needs to be restarted.

[0005] Therefore, in view of the low efficiency of manual feeding and the untimely feeding of AGVs, a double-row buffer device is equipped on the installation rack of the collaborative robot. According to the different widths of the label paper, this device can buffer 24 to 30 packs of label paper. After the label paper on the tray is used up, the collaborative robot can suck the label paper from the double-row buffer device to the input belt of the cutting machine with a suction cup. Coupled with more than 10 packs of label paper remaining on the cutting machine, generally there are at least 30 packs of label paper for the main machine to consume. It usually takes about 30 minutes to consume these label papers, which is enough time for manual or AGV feeding, thus solving the problem of material shortage and preventing the main machine from stopping due to untimely feeding.

[0045] The connecting component consists of a connecting plate 31 and a connecting block 32.

[0046] The supporting component consists of a mounting bracket 33, a supporting block 34, and a foot cup 35.

[0047] The first channel and the second channel are fixed by the connecting component. The detection system is installed on the first channel and the second channel, and the first channel and the second channel fixed by the connecting component are installed on the supporting component and connected to the bottom plate of the robot bracket 36. The double-row buffer device is as Figure 1 shown.

[0048] As Figure 2 shown, one side of the driving wheel 2, the idler wheel 3, the support rod 4, the driven wheel 5, and the flat belt support plate 6 is fixed on the first support plate 1. The flat belt 7 is sleeved on the driving wheel 2 and the driven wheel 5. The stepping motor 8 is fixed on the second support plate 10 through the stepping motor mounting plate 9, and then the other side of the driving wheel 2, the idler wheel 3, the support rod 4, the driven wheel 5, and the flat belt support plate 6 is fixed on the second support plate 10. The installation effect is as Figure 3 、 4 shown.

[0049] As Figure 5 shown, the synchronous pulley 11 is installed on the stepping motor 8, the synchronous pulley 12 is installed on the driving wheel 2, the synchronous belt 13 is sleeved on the first synchronous pulley 11 and the second synchronous pulley 12, and the synchronous belt 13, the tension adjustment component 14, the motor cover 15, and the transition plate 16 are all installed on the second support plate 10; the first cover plate 17 and the second cover plate 18 are respectively installed at both ends of the first support plate 1 and the second support plate 10, the label paper baffle 19 is installed on the second cover plate 18, and the flat belt tension adjustment component 20 is installed on the first cover plate 17.

[0050] As Figure 6 shown, the first sensor bracket 21, the second sensor bracket 22, and the third sensor bracket 23 are installed on the second cover plate 18. The first diffuse reflection sensor 24 and the second diffuse reflection sensor 25 are respectively installed on the first sensor bracket 21 and the second sensor bracket 22. The opposed sensor 26 is installed on the third sensor bracket 23. The reflector 27 is installed on the first cover plate 17. The third diffuse reflection sensor 28 is installed on the second support plate 10. The fourth sensor bracket 29 is installed on the first cover plate 17. The fourth diffuse reflection sensor 30 is installed on the fourth sensor bracket 29.

[0051] The assembly method of the second channel is the same as that of the first channel. As Figure 7 shown, the assembled first channel and second channel are fixed together through the connecting plate 31 and the connecting block 32, and the double-row buffer device is installed; the mounting bracket 33 is fixed on the connecting plate 31, the mounting bracket 33 is fixed at the bottom of the robot bracket 36, the support block 34 is installed on the connecting plate 31, and the foot cup 35 is installed on the support block 34.

[0052] Preferably, the transmission mechanism selects a stepper motor as the power source. The double-row buffer device is formed by connecting two independent single-row buffer devices in parallel. Considering the issues of economy, energy consumption level, and the control requirements of forward and reverse movement on-site, it is most appropriate to select a stepper motor. This double-row buffer device is equipped with 2 stepper motors, and each stepper motor controls the independent single-row buffer device respectively, reducing the failure rate of the double-row buffer device and enabling this buffer device to operate more smoothly at the customer site.

[0053] Preferably, the actuator selects a flat belt. Considering the practicality, usage environment, and convenience of replacement at the customer site, a flat belt is selected; and the flat belt can reduce impact and vibration during operation, run relatively smoothly, and can be selected according to the required length to adapt to various working conditions with different center distances. In order to share the weight of the material on the flat belt, a flat belt support plate is installed below the flat belt. This support plate is made of stainless steel material. When the material is placed on the flat belt, the flat belt is in direct contact with the flat belt support plate, and the flat belt pulls the material to slide on this support plate.

[0054] Preferably, the detection system selects a diffuse reflection sensor and a through-beam sensor. Since the material is a label paper, the detection accuracy does not need to be particularly high, and using a diffuse reflection sensor and a through-beam sensor can meet the on-site use requirements. The diffuse reflection sensor can be used to detect the vertical and horizontal directions of the label paper placement; the through-beam sensor is used to detect whether there is material on the flat belt. As Figure 6 shown, this sensor is generally fixed at one end close to the stepper motor, and its reflector is installed at the other end of the buffer device; when there is no label paper on the flat belt, the beam of the through-beam sensor hits the reflector, indicating that there is no material on the buffer device, and the flat belt stops working and no longer rotates; then the collaborative robot starts to grab the label paper on the other channel of the buffer device.

[0055] Preferably, a connecting block is used to connect the first channel and the second channel more tightly together, enabling the double-row buffer channel to operate more smoothly during work, greatly reducing mechanical failures caused by the loosening of the double-row buffer, and improving the work efficiency to a certain extent.

[0056] Preferably, a foot cup is used as a support. After the double-row buffer device is installed on the robot bracket, it is in a cantilever state. The foot cup is a common support member and is widely used at the customer site due to its flexible and convenient installation.

[0057] Preferably, a transition plate is installed on the support plate. Since the label paper is long and strip-shaped, one end of the label paper that is suspended may droop after being placed on the buffer device for a long time. When the flat belt works to drive the label paper to move, the suspended end of the label paper may touch the motor shield, thus changing the trajectory of the label paper. After using the transition plate, the label paper will reach the set position along the transition plate.

[0058] Take Figure 8 the application scenario of the double-row buffer device as an example for illustration. First, the 3D vision camera 37 takes pictures and locates the label paper 41 on the pallet 40 to determine the coordinate positions of each label paper in the photographed layer. The collaborative robot 38 raises the suction cup 39, and the suction cup 39 sequentially sucks the label paper according to the planned path and places the label paper on the belt at the input end of the cutting machine 42, as Figure 9 shown.

[0059] As Figure 10 、 11 shown, when the belt of the cutting machine 42 is full of label paper, the suction cup 39 starts to suck the label paper onto the double-row buffer device. First, the label paper is placed on the first channel, and after the first channel is full, it is placed on the second channel. The suction cup 39 sucks the label paper and first reaches the position above the left of the first channel according to the set path. Then the suction cup 39 sucks the label paper and slowly descends to explore the Z-direction position. When the first diffuse reflection sensor 24 detects the label paper, the label paper descends a fixed distance. Then it explores the X-direction in the horizontal position. When the second diffuse reflection sensor 25 detects the label paper, the exploration in the X-direction ends. The suction cup 39 breaks the vacuum and places the label paper on the first channel. At this time, the beam of the first diffuse reflection sensor 24 still shines on the label paper. Then the flat belt drives the label paper to move forward. When the beam of the first diffuse reflection sensor 24 does not shine on the label paper, the flat belt stops rotating, and a position for a pack of label paper will be vacated on the left side of the first channel. This vacant position is used for placing the label paper next time. The first channel is loaded with label paper according to the above steps. When the label paper is irradiated by the fourth diffuse reflection sensor 30 with an inclination angle, it indicates that the first channel is full of label paper. Then the suction cup sucks the label paper and places it on the second channel, as Figure 12 shown, to fill the second channel with label paper. The method of placing the label paper on the second channel is the same as that on the first channel, and will not be repeated here.

[0060] As Figure 13As shown, after the label paper on the pallet is used up, to grab the label paper on the double-row buffer device, first grab the label paper on the second channel and then the one on the first channel. The flat belt 7 drives the label paper to move in the reverse direction. When the third diffuse reflection sensor 28 detects the label paper, the flat belt 7 stops moving. The suction cup 39 goes to a fixed position to suck the label paper according to the pre-planned program and path. After sucking a pack of label paper, the flat belt 7 drives the label paper to move in the reverse direction again. When the third diffuse reflection sensor 28 detects the label paper, the suction cup 39 repeats the action of sucking the label paper. When the light beam of the opposed sensor 26 shines on the reflector 27, it indicates that the second channel is out of stock and there is no label paper, and the suction cup 39 starts to grab the label paper on the first channel. The method of grabbing the label paper on the first channel is the same as that on the second channel, which will not be repeated here.

[0061] The working beats of the stepping motor and the collaborative robot on the double-row buffer device can both be changed, so as to better meet the requirements of various packaging speeds of the tobacco packaging machine.

[0062] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
