Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a double synchronous belt steering conveying device and a conveying system. Background Art

[0002] The cigarette packaging unit primarily consists of a small-box packaging machine, a small-box cellophane packaging machine, a strip-box packaging machine, and a strip-box cellophane packaging machine. Due to factors such as equipment layout, after the small-box packaging machine completes the packaging of small cigarette packs, they need to be rotated or flipped before being conveyed to the cellophane packaging machine to meet the packaging requirements of the cellophane packaging machine. Depending on the packaging unit layout, the small packs require different positioning adjustments. Currently, the passive flipping or rotation of small cigarette packs during conveyor transport in low-speed packaging machines cannot meet the requirements of medium- and high-speed production, affecting production efficiency and packaging quality.

[0003] In order to solve the technical problems existing in the prior art, the utility model proposes a double synchronous belt steering conveying device and a conveying system for small cigarette packs.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] In the first aspect, the utility model provides a double-synchronous belt steering conveying device for small-box cigarette packs, including a servo motor, a driven pulley, a driving pulley, a driven shaft, a cigarette scraping synchronous belt and a cigarette shifting synchronous belt; the servo motor drives the driving pulley, the driving pulley is connected to the driven pulley through the cigarette scraping synchronous belt and the cigarette shifting synchronous belt, the driven pulley is installed on the driven shaft, a first scraper is fixed on the cigarette scraping synchronous belt, and a shift block and a baffle are installed on the first scraper; the shift block is fixed on the front side of the first scraper, and the baffle is fixed on the rear side of the first scraper; a second scraper is fixed on the cigarette shifting synchronous belt, and there is a set phase difference between the first scraper and the second scraper.

[0006] The phase difference between the scrapers on the scraping and shifting belts can be adjusted to suit the size of the cigarette packs. This ensures that after the small packs have completed their rotation, the scrapers follow closely and push the small packs onto the downstream conveyor. As the packs rotate, a baffle follows the shifting block, separating the following packs from the rotating packs, preventing pack compression that could cause equipment downtime and impact production efficiency.

[0007] As a further technical solution, the servo motor is mounted on a motor mounting plate, the driven shaft is mounted on a fixed plate, and the motor mounting plate is mounted on the fixed plate through a guide groove.

The threaded end of the adjustment screw is screwed into the adjustment fixing block, and the head supports the motor mounting plate.

[0010] As a further technical solution, a plurality of first scrapers are fixed at intervals on the cigarette scraping synchronous belt, and a shifting block and a baffle are installed on each first scraper; correspondingly, a plurality of second scrapers are fixed at intervals on the cigarette scraping synchronous belt; that is, the multi-station design of the cigarette scraping synchronous belt and the cigarette scraping synchronous belt improves the working capacity of the entire mechanism, thereby meeting the production requirements of medium and high-speed cigarette packaging machines.

[0011] As a further technical solution, a turning guide rail is provided on the outer side of the cigarette pulling synchronous belt.

[0012] As a further technical solution, the surface of the shifting block that contacts the cigarette pack is arc-shaped.

The mechanism is driven by a servo motor and can meet the production requirements of medium and high-speed packaging equipment. The mechanism is simple, easy to control, stable and reliable. The device is installed at the right-angle turn of the conveyor, and the servo motor drives two double-station synchronous belts at the same time, of which the first one on the outside is a cigarette-pulling synchronous belt, and the second one on the inside is a cigarette-scraping synchronous belt. When the small box of cigarette packs arrives at the device under the conveyor, the servo motor receives a signal and drives the two synchronous belts to rotate at the same time.

Therefore, they cannot be understood as limiting the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, an internal connection between two elements, or an interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] This embodiment provides a method for rotating a small cigarette pack by 90 degrees and changing the conveying direction (see attached Figure 1 ) mechanism, which is driven by a servo motor and can meet the production requirements of medium and high-speed packaging equipment. The mechanism is simple, easy to control, stable and reliable. The device is installed at the right-angle turn of the conveyor (attached Figure 4 ) A servo motor simultaneously drives two double-station timing belts: the first on the outside is the cigarette-pulling belt, and the second on the inside is the cigarette-scraping belt. When a small cigarette pack arrives at this device on the conveyor, the servo motor receives a signal to simultaneously rotate both timing belts. The shifting block on the cigarette-pulling belt first contacts the cigarette pack, rotating it 90° counterclockwise. Then, the scraper on the cigarette-scraping belt pushes the small cigarette pack onto the oil-removing conveyor, completing the entire cigarette pack transfer process.

[0027] Specifically, the structure of the present invention is further described with reference to the accompanying drawings:

[0028] like Figure 2 、 Figure 3 As shown, the double-synchronous belt steering conveyor for small cigarette packs proposed in this embodiment is composed of a driven pulley 1, a fixed plate 2, a motor mounting plate 3, a driving pulley 4, a shift block 5, a baffle 6, a scraper 7, a servo motor 8, a cigarette scraping synchronous belt 9, a cigarette shifting synchronous belt 10, an adjustment fixed block 11, a locking nut 12, an adjustment screw 13, and a driven shaft 14.

[0029] The servo motor 8 is mounted on the motor mounting plate 3, and the driving pulley 4 is connected to the servo motor 8 via a key. The servo motor 8 directly drives the driving pulley 4. The driven shaft 14 is fixed to the fixed plate 2 by a jackscrew, and the driven pulley 1 is mounted on the driven shaft 14 via a bearing. The driving pulley 4 drives the driven pulley 1 to rotate via the parallel smoke scraping timing belt 9 and the smoke plucking timing belt 10. The motor mounting plate 3 is mounted on the fixed plate 2 via a guide groove; the adjustment block 11 is mounted on the fixed plate 2. The threaded end of the adjustment screw 13 is screwed into the adjustment block 11, and the head presses against the motor mounting plate 3, keeping the motor mounting plate 3 fixed in place. This ensures that the servo motor 8 is fixed, and the driving pulley 4 and the driven pulley 1 always maintain the set distance, so that the smoke scraping timing belt 9 and the smoke plucking timing belt 10 remain in a constant tension state.

[0030] Furthermore, two scrapers 7 are equally bonded to the tobacco scraping synchronous belt 9 and the tobacco shedding synchronous belt 10. The main function of the scrapers 7 on the tobacco shedding synchronous belt 10 is to push the cigarette packs into the downstream conveyor after the cigarette packs complete a 90° turn. The main function of the scrapers 7 on the tobacco shedding synchronous belt 9 is to install the shifting blocks 5 and the baffles 6. That is, the scrapers 7 in the tobacco shedding synchronous belt 10 are also provided with shifting blocks 5 and baffles 6. The shifting blocks 5 are fixed to the front side of the scrapers 7, and the baffles 6 are fixed to the rear side of the scrapers 7. During the forward movement of the tobacco scraping synchronous belt 9, the shifting blocks 5 will first contact the cigarette packs. Then, as the tobacco scraping synchronous belt 9 moves forward, the shifting blocks 5 will slowly rotate the cigarette packs 90° counterclockwise. At the same time, the baffles 6 will block the subsequent cigarette packs to prevent them from squeezing. That is, when the cigarette packs rotate, the baffles follow the shifting blocks and separate the subsequent cigarette packs from the rotating cigarette packs to prevent the cigarette packs from squeezing and causing equipment shutdown, thereby affecting production efficiency.

[0031] It should be noted that a scraper 7 can be set at every distance on the smoke scraping synchronous belt 9, and a shift block 5 and a baffle 6 are installed on each scraper 7; the specific number of settings is set according to the length of the smoke scraping synchronous belt 9.

[0032] It should be noted that scrapers 7 are installed at regular intervals on the cigarette plucking synchronous belt 10; the specific number of scrapers 7 is determined by the length of the cigarette plucking synchronous belt 10. This multi-station design of the cigarette plucking and scraping synchronous belts improves the overall operating capacity of the entire mechanism, thereby meeting the production requirements of medium- and high-speed cigarette packaging machines.

[0033] Furthermore, the scraper 7 in the cigarette plucking synchronous belt 10 is ahead of the scraper 7 in the cigarette scraping synchronous belt 9 by a certain phase, which can be appropriately adjusted according to the size of the cigarette pack. The purpose of such design is mainly because the scraper 7 in the cigarette scraping synchronous belt 9 is required to push the cigarette pack into the downstream conveyor only after the plucking block 5 on the cigarette plucking synchronous belt 10 rotates the cigarette pack 90°. There is a time difference between the two actions. Therefore, the scraper 7 in the cigarette plucking synchronous belt 10 is ahead of the scraper 7 in the cigarette scraping synchronous belt 9 by a certain phase.

[0034] Furthermore, the phase difference between the scrapers 7 on the scraping and pushing synchronous belts can be adjusted according to the size of the cigarette packs, ensuring that after the small cigarette packs are rotated, the scrapers are in place and push the small cigarette packs to the downstream conveyor.

[0035] As a further technical solution, a turning guide rail is provided on the outside of the cigarette synchronous belt 10. During the entire rotation process, the small cigarette packs rotate around the turning guide rail due to the power provided by the conveyor, and are close to the turning guide rail after the rotation is completed.

[0036] Furthermore, this embodiment also provides a delivery system, such as Figure 1 、 Figure 4As shown, it includes an upstream conveyor and a downstream conveyor, and the aforementioned small box cigarette pack double synchronous belt steering conveying device is installed between the upstream conveyor and the downstream conveyor; the conveying directions of the upstream conveyor and the downstream conveyor are set vertically; the small box cigarette pack double synchronous belt steering conveying device is installed at the intersection of the upstream conveyor and the downstream conveyor.

[0037] As a further technical solution, a photoelectric sensor is further installed in the conveying system. The photoelectric sensor is connected to the control system of the servo motor. The control system controls the rotation of the servo motor according to the signal of the photoelectric sensor.

[0038] As a further technical solution, the surface of the shifting block that contacts the cigarette pack is arc-shaped.

[0039] As a further technical solution, the surface of the shifting block in contact with the cigarette pack is provided with a protective layer.

[0040] Specifically, the working process is as follows:

[0041] When cigarette packs are transported along the conveyor belt to this mechanism, small packs are transported by the upstream conveyor to the pack arrival detection plate. The photoelectric sensor receives the small pack arrival signal, and the control system controls the servo motor 8 to rotate the driving pulley 4, which in turn rotates the cigarette plucking and scraping belts 10 and 9. The plucking block 5 first contacts the cigarette pack, rotating it 90° counterclockwise. At the same time, the baffle 6 blocks subsequent cigarette packs to prevent squeezing.

[0042] During the entire rotation process, the power provided by the conveyor causes the small cigarette pack to rotate around the steering guide rail and cling to the steering guide rail after the rotation is completed. At this time, the scraper 7 on the cigarette scraping synchronous belt 9 is in place and pushes the small cigarette pack into the downstream conveyor, completing the entire process of cigarette box steering and transportation.

[0043] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0044] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
