Description

Technical Field

[0001] This utility model relates to the field of gripping and transferring technology, and in particular to a cigarette pack gripping and transferring device. Background Technology

[0002] Currently, on cigarette packaging production lines, gripping devices with multiple vacuum suction cups are commonly used to automate the feeding of cigarette packs.

[0003] A search revealed that Chinese patent publication number CN221498610U discloses a cigarette pack gripping and transferring device, which uses a vacuum suction cup to grip the cigarette pack.

[0004] However, existing devices of this type have several obvious drawbacks: First, their suction cups are usually fixed on a rigid bracket, and the spacing between the suction cups is not adjustable, making it impossible to flexibly adapt to cigarette packs of different sizes, resulting in poor equipment versatility; second, when a single suction cup or its central seal is damaged, it is often necessary to disassemble and replace the entire suction cup module or even a section of the gripping beam, making maintenance cumbersome, time-consuming, and costly; more importantly, existing devices generally lack reliable, real-time monitoring of the working status of each suction cup. They typically only monitor the pressure of the main vacuum pipeline and cannot detect whether a suction cup at the end has lost its suction force due to failure to adhere to the cigarette pack surface, blockage, or breakage. This "group control" monitoring method has blind spots, which can easily lead to quality accidents and production interruptions during gripping or transfer due to the failure of individual suction cups, resulting in cigarette pack detachment, jamming, or missing packs, indicating insufficient reliability.

[0005] Therefore, we propose a cigarette pack grabbing and transfer device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cigarette pack grabbing and transfer device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a cigarette pack grabbing and transferring device, including a connecting seat, an aluminum alloy truss fixedly connected to the bottom of the connecting seat, a T-slot opened at the bottom of the aluminum alloy truss, and a plurality of movable frames slidably connected to the bottom of the aluminum alloy truss, and each of the plurality of movable frames and the T-slot is installed with two bolt pressing and fixing components.

[0008] Each of the aforementioned movable frames has two symmetrically arranged elongated slots extending to the bottom at its top. Each of the aforementioned elongated slots has a sleeve that slides inside it. Each of the aforementioned sleeves has a retaining ring fixedly fitted onto its outer surface. Each of the aforementioned sleeves has a nut threaded onto its outer surface. An elastic component is installed inside the sleeve. A vacuum nozzle is fixedly connected to the movable end of the elastic component.

[0009] A connecting joint is fixedly connected to one side of the outer surface of several vacuum nozzles. An installation joint is threadedly fitted onto the outer surface of the connecting joint. A hose is fixedly connected to one end of the installation joint. A housing is fixedly connected to the end of the hose. A pressure detection component is fixedly connected to the inner top wall of the housing.

[0010] Furthermore, several of the bolt pressing and fixing components include connecting bolts, which extend through the bottom of the movable frame into the T-slot. The outer surface of the connecting bolt is threaded with a pressure block, which rubs against the inner bottom wall of the T-slot. This structure allows the movable frame to achieve stepless adjustment and quick locking at any position throughout the entire length of the T-slot.

[0011] Furthermore, several of the retaining rings are attached to the bottom of the movable frame, and several of the nuts are attached to the top of the movable frame. This clamping structure uses the retaining rings and nuts to securely install the sleeve assembly onto the movable frame.

[0012] Furthermore, each of the aforementioned elastic components includes two springs, which are respectively fixedly connected to the inner top wall and inner bottom wall of the sleeve. The two springs are fixedly connected to a movable ring at their adjacent ends, and the movable ring is fixedly sleeved on the outer surface of the vacuum nozzle. The symmetrically arranged double-spring structure provides balanced and stable axial floating support for the vacuum nozzle.

[0013] Furthermore, several of the sleeves are slidably fitted onto the outer surface of the vacuum nozzle. The sliding fit structure provides guidance for the up-and-down movement of the vacuum nozzle, ensuring that its movement under the action of the elastic component is smooth and without jamming.

[0014] Furthermore, several of the aforementioned air pressure detection components include a tension sensor, which is fixedly connected to the inner top wall of the housing. The detection end of the tension sensor is fixedly connected to a piston, and the piston is sealed and fitted to the inner wall of the housing. This design directly converts the vacuum negative pressure into the mechanical displacement of the piston, and then generates a precise electrical signal through the tension sensor, realizing the direct, independent, and real-time measurement of the adsorption force of a single vacuum nozzle.

[0015] The beneficial effects of this utility model are:

[0016] In use, this invention achieves flexible and reliable adjustment of the vacuum nozzle spacing through the sliding cooperation of the aluminum alloy truss, T-slot, and movable frame. The assembly structure of the sleeve, retaining ring, and nut, along with the locking method of the connecting bolts and pressure blocks, facilitates independent disassembly and maintenance of both the movable frame and the vacuum nozzles. The integrated air pressure detection component within the housing independently and in real-time monitors the adsorption status of each vacuum nozzle, effectively preventing cigarette pack detachment due to the failure of a single nozzle, thus significantly improving the equipment's adaptability, ease of maintenance, and reliability of the gripping operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5As shown, a cigarette pack gripping and transferring device is disclosed, including a connecting seat 2. An aluminum alloy truss 4 is fixedly connected to the bottom of the connecting seat 2. A T-slot 14 is opened at the bottom of the aluminum alloy truss 4. Several movable frames 3 are slidably connected to the bottom of the aluminum alloy truss 4. Each of the movable frames 3 and the T-slot 14 is installed with two bolt pressing and fixing components. Each of the bolt pressing and fixing components includes a connecting bolt 8, and the connecting bolt 8 extends through the bottom of the movable frame 3 into the T-slot 14. A pressure block 9 is threaded on the outer surface of the connecting bolt 8, and the pressure block 9 rubs against the inner bottom wall of the T-slot 14. An anti-slip rubber pad is fixedly connected to the bottom of the pressure block 9 to increase the friction of the pressure block 9 during use and improve the locking effect.

[0027] Each of the movable frames 3 has two symmetrically spaced elongated slots 1 extending to the bottom. Each of the elongated slots 1 has a sleeve 7 sliding inside it. Each of the sleeves 7 has a retaining ring 6 fixedly fitted on its outer surface. Each of the sleeves 7 has a nut 15 threadedly fitted on its outer surface. Each retaining ring 6 is attached to the bottom of the movable frame 3. Each nut 15 is attached to the top of the movable frame 3. An external thread is provided on the outer surface of the sleeve 7, and the external thread is threadedly connected to the nut 15, which can realize the quick installation of the sleeve 7.

[0028] The sleeve 7 has an elastic component installed inside. The movable end of the elastic component is fixedly connected to the vacuum nozzle 5. Each elastic component includes two springs 16, and the two springs 16 are fixedly connected to the inner top wall and inner bottom wall of the sleeve 7, respectively. The adjacent ends of the two springs 16 are fixedly connected to a movable ring 17, and the movable ring 17 is fixedly sleeved on the outer surface of the vacuum nozzle 5. The sleeves 7 are slidably sleeved on the outer surface of the vacuum nozzle 5. When the vacuum nozzle 5 contacts the surface of the cigarette pack, the height difference of the cigarette pack stack can be adapted by compressing the springs 16 to ensure that each nozzle can fit tightly, thereby forming an effective seal.

[0029] Several vacuum nozzles 5 have connecting joints 10 fixedly connected to one side of their outer surfaces. A mounting joint 13 is threadedly fitted onto the outer surface of the connecting joint 10. A flexible hose 11 is fixedly connected to one end of the mounting joint 13, and a housing 12 is fixedly connected to the end of the flexible hose 11. A pressure detection assembly is fixedly connected to the inner top wall of the housing 12. Each pressure detection assembly includes a tension sensor 18, which is fixedly connected to the inner top wall of the housing 12. A piston 19 is fixedly connected to the detection end of the tension sensor 18, and the piston 19 is sealed to the inner wall of the housing 12. The modular design of the connecting joints 10 and mounting joints 13 facilitates quick connection and disconnection of the air path. The flexible hose 11 has a certain degree of flexibility and length, ensuring unobstructed airflow without hindering the necessary floating movement of the vacuum nozzles 5. An air hole is provided at the top of the housing 12 to balance the air pressure.

[0030] The connecting seat 2 is fixedly connected to the drive end of the existing external mobile control mechanism, the vacuum nozzle 5 is fixed to the vacuuming end of the existing external vacuum system, and the tension sensor 18 is controlled by the PLC controller used by the existing external vacuum system. Its model is ZZ310-070 spoke-type tension and pressure sensor.

[0031] Working principle: The operator adjusts the position of the vacuum nozzle 5 according to the cigarette pack specifications. First, loosen the connecting bolt 8 to increase the distance between the screw head and the pressure block 9. Then, push the connecting bolt 8 up. The connecting bolt 8 drives the pressure block 9 to rise, causing it to disengage from the inner bottom wall of the T-slot 14. Then, manually push the movable frame 3 to move along the aluminum alloy truss 4. After determining the position, tighten the connecting bolt 8. Utilize the friction between the pressure block 9 and the bottom surface of the T-slot 14 to firmly lock the movable frame 3.

[0032] The vacuum nozzle 5 and its connected sleeve 7 assembly are passed through the elongated slot 1 on the movable frame 3. A retaining ring 6 is fitted onto the lower end of the sleeve 7, and a nut 15 is screwed onto the upper end. By tightening the nut 15, the sleeve 7 is clamped and fixed on the movable frame 3. The vacuum nozzle 5 can float axially within the sleeve 7. Its floating is supported by an elastic structure consisting of a spring 16 and a movable ring 17, ensuring that each nozzle can adaptively conform to the surface of the cigarette pack.

[0033] Screw the mounting connector 13 at one end of the hose 11 into the connecting connector 10 on the vacuum nozzle 5. Connect the other end of the hose 11 to the housing 12 of the integrated pressure detection assembly.

[0034] During the gripping operation, the connecting seat 2 lowers the device under the drive of the external movement control mechanism. When each vacuum nozzle 5 contacts the cigarette pack, it compresses its respective spring 16, achieving independent cushioning and tight contact.

[0035] The external vacuum system is activated, and negative pressure is transmitted through the hose 11 and the inner cavity of the housing 12 to the vacuum nozzle 5, adsorbing the cigarette pack. The negative pressure creates a pressure difference between the inside of the housing 12 and the atmosphere, pulling the piston 19 downward. The piston 19 directly pulls the detection end of the tension sensor 18 fixed to it. The tension sensor 18 converts the mechanical displacement into an electrical signal and outputs it. The external control system monitors this signal in real time: if the signal value is consistently higher than the set threshold, it indicates that the vacuum nozzle 5 is firmly adsorbed; if the signal is too low or fluctuates, it is immediately determined that the point has failed.

[0036] After all tension sensor 18 signals are confirmed to be normal, the device is lifted and the cigarette pack is transported. Throughout the transport process, the tension sensor 18 continuously provides monitoring data to prevent the risk of it falling off midway.

[0037] Upon reaching the target location, the vacuum system switches to vacuum breaking mode. The vacuum nozzle 5 releases the cigarette pack, the air pressure inside and outside the housing 12 is balanced, the piston 19 connected to the tension sensor 18 resets under the action of force, the signal returns to zero, and the entire system prepares for the next cycle.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
