Description

Technical Field

[0001] The invention relates to the technical field of wine bottle preparation and processing technology, and specifically to an automated processing technology for fixing, positioning, labeling and sorting wine bottles. Background Art

[0002] In the normal production process, wine bottles need to be labeled after the firing and shaping process is completed. The general wine bottle labels on the market are mainly divided into the corresponding wine product name (large label) and the winery trademark (circular label), which are affixed to different positions of the wine bottle. Since the main body of the wine bottle is basically cylindrical without special design, it is impossible to use traditional flat labeling machines for automatic labeling operations. In addition, with the improvement of aesthetic level and bottle making technology in recent years, non-traditional cylindrical special-shaped bottles have gradually become mainstream, and irregular curved surfaces have further increased the difficulty of automatic labeling.

[0003] At present, the labeling work for special-shaped bottles is mainly carried out by skilled labelers along the production line. Since wine bottle stickers are mostly water-based stickers, the labels are firm but the stickers themselves are very fragile and easily damaged. In addition, as a promotional tool, wine bottle labels have extremely high requirements for appearance. This puts very high demands on the proficiency and concentration of the workers. If the production rate or product quantity is increased, the labor cost will be further increased. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic labeling production line process for special-shaped bottles, overcome the shortcomings of the aforementioned prior art, and adopt the automatic labeling process. The equipment has a compact structure, greatly reduces the occupied space, has a high degree of automation and easy transformation, can effectively reduce the participation of skilled workers, and effectively improve the labeling qualification rate and finished product output rate.

[0005] The technical solution adopted by the present invention to solve the technical problem is: An automatic labeling process for special-shaped bottles, comprising wine bottle loading - wine bottle body preheating - large label flower paper loading - large label flower paper positioning - large label flower paper watering - large label labeling - large label center scraping - large label surrounding scraping - round label flower paper loading - round label flower paper positioning - round label flower paper watering - round label flower paper pressing - round label labeling - round label pressing and watering - round label upper and lower watering - flipping the next bottle; the main body of the equipment for the labeling process is as follows: a stepping annular conveyor (1), an external heating device is arranged along the starting point of the long side of the annular conveyor and the stepping running direction of the conveyor line The invention relates to a step-by-step circular conveyor (1), a large label labeling mechanism (3), a large label wiper mechanism (4), a round label labeling mechanism (5), a round label wiper mechanism (6) and a bottle flipping mechanism (7), all of which are arranged along the circular conveyor body for one circle; the main body of the step-by-step circular conveyor body (1) is a set of customized step-by-step circular conveyor lines (1.3), which are installed on two split conveyor line frames (1.1) with the same structure and locked to each other; the external heating furnace (2) is used to heat the wine bottles to be labeled to a temperature suitable for labeling during transportation; the large label labeling mechanism (5) is used to heat the wine bottles to be labeled to a temperature suitable for labeling. The labeling mechanism (3) takes out the flower paper containing the large label sticker from the flower paper box (3.1.2.1) and places it in the storage slot for the process of fixing, labeling and labeling, so as to facilitate the separation of the sticker and the flower paper. Finally, the labeling component (3.3) absorbs the large label sticker and places it on the designated position of the passing wine bottle; the large label wiping mechanism (4) performs multiple center squeezing and surrounding squeezing wiping actions on the passing wine bottle with the large label to complete the large label wiping process; the function of the round label labeling mechanism (5) is the same as that of the large label labeling mechanism (3). The structure and function are basically the same, and it is responsible for taking out the round label paper from the paper box and fixing and moistening it, and finally separating the round label from the paper and sticking it on the designated position of the wine bottle; the round label wiper mechanism (6) has the same function as the large label wiper mechanism (4), and is responsible for performing multiple squeezing and wiping actions on the wine bottles that have been pasted with round labels to complete the round label scraping process; the flip bottle picking mechanism is used to take out all the wine bottles that have completed the labeling operation from the stepping conveyor line in batches, and flip them to a positive position so as to be placed on the conveyor line of the external equipment.

[0006] Furthermore, the main body of the step-by-step circular conveyor (1) is a customized step-by-step circular conveyor line (1.3), and the conveyor line is provided with sufficient mounting base plates according to the number of steps for mounting the self-locking wine bottle fixing seat (1.5) described later; the step-by-step circular conveyor line (1.3) is mounted on a combination of two split conveyor frames of the same structure and is firmly locked, and the frame is welded with high-strength steel pipes and further welded and reinforced at the joints to ensure that the frame will not shake or resonate as a whole during the operation of the conveyor line, and can also carry the mounting or support of equipment in other components; considering that the overall length of the conveyor frame makes it difficult to transport, the two frames are connected at the joints using male and female connectors to ensure that disassembly is convenient while ensuring that there is no relative displacement, and to facilitate maintenance and transportation.

[0007] Furthermore, in the process of heating the wine bottle body, the external heating furnace (2) is a standard controllable baking furnace for a conveyor line, which is mounted on a split conveyor frame. The baking space is for the stepping conveyor line to pass through but does not contact the conveyor line. It is used to heat the passing wine bottles to a temperature suitable for labeling, while also preventing the possibility of physical deformation of the bottles due to extremely low temperatures that may occur at the location of the production line. The furnace temperature can be adjusted and maintained as needed, making it easy to change the production plan.

[0008] Furthermore, in the large label flower paper loading-large label labeling series process, the large label labeling mechanism (3) is installed after the external heating furnace (2), and the main body is arranged on a support frame (4.1) placed parallel to the long side of the split conveying frame and the internal label taking component (3.1), turntable component (3.2), and labeling component (3.3); the label taking component (3.1) sucks the flower paper with the large label sticker from the flower paper box (3.1.2.1) and transfers it to the turntable component (3.2) to complete the fixing, labeling, and wetting operations. After completion, the position of the large label sticker is basically determined and it is easy to peel off from the flower paper. The labeling component (3.3) sucks the large label sticker and sticks it on the specified position of the wine bottle passing and staying directly below the mechanism; the whole set of actions are automatically controlled and operated by the production line, and no human intervention is required except for replenishing the flower paper and cleaning up the waste.

[0009] Furthermore, the label taking component (3.1) is installed on the top of the supporting frame (4.1), and the main body is a general rectangular coordinate robot (3.1.1) equipped with a suction cup gripper. The general rectangular coordinate robot (3.1.1) controls the suction cup gripper at the end of the Y-axis column (3.1.1.2) by lifting and lowering the Y-axis column (3.1.1.2) and translating the Y-axis column (3.1.1.2) to complete the cycle of sucking flower paper from the flower paper box (3.1.2.1) - lifting and transferring the flower paper - placing the flower paper into the storage slot - taking out the waste flower paper in the storage slot - placing the waste flower paper into the waste paper recycling box (3.1.2.2); the robot movement is completed by the servo motor (3.1.1.4) installed on the shaft to control the rack to move along the gear, and the suction cup gripper is composed of pure pneumatic components, so the accuracy of the expected movement can be guaranteed.

[0010] Furthermore, the main body of the turntable assembly (3.2) is a circulating four-station disc (3.2.1.1) installed on the other side of the support frame (4.1). The disc is driven by a servo motor (3.1.1.4) installed in a motor frame on the support frame (4.1) at its top, and rotates 90° counterclockwise each time to make a stepping motion; four groups of grooves are engraved on the disc, and holes are opened in the grooves and a plurality of suction cup groups (3.1.1.5.1) are installed in an array to absorb air upwards; starting from the storage slot close to the landing point of the suction cup gripper of the label picking assembly (3.1), the suction cup groups (3.1.1.5.1) are divided into The label placement, label adjustment, label wetting, label transfer and label removal processes are completed separately; the top of each groove is covered by a cover plate (3.2.1.2), and the end of the cover plate arm (3.2.1.3) is pulled by a spring installed at the bottom of the four-station circular disc (3.2.1.1) to maintain a normally closed state. Only when the large label flower paper is loaded and the large label is labeled, the cover plate cylinder (3.2.1.4) installed on the power frame (3.2.3) pops up downward and presses the cover plate arm (3.2.1.3), thereby lifting the cover plate (3.2.1.2); when the flower paper falls into the storage slot, The suction cup array starts to evacuate air, fixing the decal paper in the groove, and then the cover plate cylinder (3.2.1.4) contracts upward, and the cover plate (3.2.1.2) is lowered to further flatten the decal paper to complete the large label decal paper loading process; since the large label and round label used on the wine bottle are essentially water-based stickers, they need to be removed from the decal paper and transferred to the position to be pasted in a humid environment, so a complete set of water circulation components (3.2.2) is set on the labeling frame (3.5) for wetting the decal paper: a movable self-heating and heat-insulating water tank (3.4) is set next to the labeling frame (3.5) To provide heated hot water, the hot water is acted upon by a self-priming water pump (3.2.2.1), rises along the pipeline and enters the water outlet (3.2.2.3), and sprays along the outlet hose (not shown) onto the groove of the cover plate (3.2.1.2). Excess water leaves the circulating four-station disc (3.2.1.1) along the array holes without suction cups mentioned above, and falls into the recovery water tank (3.2.2.2) below, and finally returns from the recovery water tank (3.2.2.2) along the pipeline to the self-heating insulation water tank (3.4) to complete the water cycle.

[0011] Furthermore, in order to prevent the stickers on the decal paper from being overly softened due to the direct flushing of the water flow on the decal paper, thereby causing deviation and affecting the positioning, the cover plate (3.2.1.2) in the large label labeling mechanism (3) and the round label labeling mechanism (5) is lined with hard steel wool to filter and buffer the falling water flow. The water flow cannot directly flush the decal paper, but it can still moisten the decal paper.

[0012] Furthermore, when the groove carrying the flower paper continues to rotate 180°, it enters the label picking process. The main body of the label picking component (3.3) is two six-axis robots (3.3.1) arranged on the split conveyor line frame (1.1). When the groove carrying the flower paper steps into the area, the cover plate cylinder (3.2.1.4) located above the cover plate arm (3.2.1.3) pops up downward to press the cover plate to pop open, and the six-axis robot (3.3.1) carries the flexible large label membrane gripper (3.3.2) close to , the large label sticker is adsorbed on the porous silicone membrane skin (3.3.2.6) of the suction cup gripper, and then the six-axis robot (3.3.1) controls the flexible large label membrane gripper (3.3.2) to approach the specified position of the wine bottle, press the sticker on the wine bottle, the gripper removes the suction force, and controls the telescopic silicone block (3.3.2.4) to squeeze the large label sticker through the skin. After repeating several times, the sticker is attached to the wine bottle, and then the wine bottle leaves, the groove rotates 90° again to return to the starting point, and a new round of labeling process begins again.

[0013] Furthermore, since the wine bottle still contains a large amount of water at the location of the large label after being labeled with a large label, and the large label is only positioned on the wine bottle but not completely fixed; therefore, a large label scraping mechanism (4) is designed to scrape off excess water and fix the large label; the large label scraping mechanism (4) is installed after the large label labeling mechanism (3) and fixed on the split conveyor line frame (1.1), wherein the main mechanism of the large label labeling mechanism (3) is a support frame (4.1) and a scraper frame (4.2), and the scraper mechanism completes the process of center water hanging or surrounding water scraping according to the large label center scraper (4.7.5) or large label edge scraper (4.7.6) installed in the scraper frame (4.7.4) inside the scraper frame (4.7.4); the scraper frame (4.2) is embedded in the support frame (4.1) and moves along the track line (4.4) in the support frame (4.1). ) moves; the center of the large label scraping mechanism (4) is fixedly installed with a customized wine bottle contour plate (4.5), and the scraper frame (4.2) is driven by a rodless cylinder (4.6) in the support frame (4.1). When moving along the track rail (4.4), the floating scraper bracket (4.8) in the scraper frame (4.2) is restricted by the contour of the customized wine bottle contour plate (4.5) and floats up and down along the outer contour of the wine bottle through the roller (4.9), and the scraper frame (4.7.4) carries the large label center scraper (4.7.5) or the large label surrounding scrapers (4.7.6) close to the large label sticker and moves along the contour of the bottle body, completing the center hanging water and surrounding scraping of the large label sticker and fixing the large label; in addition, since the large label scraper and the customized wine bottle contour plate (4.5) are designed with replacement space, this production line supports labeling of special-shaped bottles of other shapes after certain modifications.

[0014] Furthermore, the round labeling process is substantially the same as the large label labeling workflow described above; the round label labeling mechanism (5) is installed behind the large label wiper mechanism (4), and the main body is a support frame (4.1) arranged parallel to the long side of the split conveying frame and a round label picking component (5.1), a round label turntable component (5.2), and a round label labeling component (5.3) inside; the round label picking component (5.1) sucks the flower paper with the round label sticker from the flower paper box (3.1.2.1), and transfers it to the round label turntable component (5.2) to complete the positioning, watering, and pressing operations. After completion, the position of the round label sticker is basically determined and it is easy to peel off from the flower paper. The round label labeling component (5.3) sucks the round label sticker and sticks it on the designated position of the wine bottle passing and staying directly below the mechanism; the whole set of actions is automatically controlled and operated by the production line, and no human intervention is required except for replenishing the flower paper and cleaning up the waste.

[0015] Furthermore, the round label labeling mechanism (5) is different from the large label labeling mechanism (3) in that the platform used to carry the decals to complete loading-positioning-watering-pressing is a reciprocating two-station turntable. The round label is different from the large label in that the shape is neat and the area of ​​a single sticker is small. The carrying capacity of a single decal is large, but it requires more precise positioning to facilitate labeling. Therefore, the reciprocating two-station turntable (5.2.3.2) is only set with a stop position during the labeling and labeling process, and when the decals are placed on the positioning component, they will be mechanically fixed by an additional end spring cover plate (5.2.3.1.3) and normally closed; when the decals need to be replaced, the top unlocking mechanism (5.2.6) controls the unlocking frame (5.2.6.2) to descend and simultaneously open the end spring cover plates (5.2.3.1.3) at both ends to unlock and fix; in addition, the pressing mechanism (5.2.7) carries the cover plate to press the round label decal again from above to further flatten the decal and ensure accurate positioning.

[0016] Furthermore, based on the design concept of the wine bottle, a separate plane is usually designed when designing the appearance of the wine bottle to stick the trademark (round label), so the labeling assembly of the round label will be different from the large label part; the round label labeling assembly (3.3) is a six-axis robot (3.3.1) carrying a round label suction cup gripper (5.3.1) (5.1.1), which is different from the flexible large label membrane gripper (3.3.2) in that the round label suction cup gripper (5.3.1) (5.1.1) is only a pneumatic suction cup installed on a telescopic cylinder. After the suction cup approaches the round label flower paper, the suction cup draws air to adsorb the round label on the suction cup; the suction cup carries the sticker close to the plane of the wine bottle, and controls the suction cup to squeeze toward the plane, and finally leaves the round label on the designated plane.

[0017] Furthermore, since the wine bottle still contains a large amount of water at the location of the round label after being labeled with the round label, and the round label is only positioned on the wine bottle but not completely fixed; therefore, a round label scraping mechanism (6) is designed to scrape off excess water and fix the round label; when the self-locking wine bottle fixing seat (1.5) carries the wine bottle into the working range of the round label scraping mechanism (6), the scraping frame (6.4) is driven by the frame cylinder (6.5) to move downward along the scraping line rail (6.3); the round label scraper assembly (6.6) installed on the scraping frame (6.4) approaches the wine bottle (1.4) to prepare for subsequent scraping operations; the scraper arm carries the round label pressing head (6.6.5) approaches the round label pasting position of the wine bottle (1.4) and squeezes it to squeeze out the moisture on the round label to the position where the round label is located; the round label wiper mechanism (6) 2 is installed after the round label wiper mechanism (6) 1; similarly, after the self-locking wine bottle fixing seat (1.5) carries the wine bottle into the working range of the round label wiper mechanism (6), the scraper frame (6.4) is driven by the frame cylinder (6.5) to move downward along the scraper linear rail (6.3); the scraper arm carries the round label scraper (6.6.4) to move up and down close to the round label pasting position of the wine bottle (1.4), squeezes out the moisture on the round label to the position where the round label is located to complete the fixation of the large label sticker.

[0018] Furthermore, the bottle flipping and picking mechanism is arranged behind the round label wiper mechanism (6), separated from the external heating furnace (2) by a certain distance and close to the split conveyor line frame (1.1); the main body is a general rectangular coordinate robot (3.1.1) mounted on a grounding column and carrying a wine bottle flipping gripper (7.2.3). After the wine bottle that has completed the labeling process enters the designated position, the wine bottle gripper (7.2.3.2) approaches the self-locking wine bottle fixing seat (1.5), releases the wine bottle lock and grabs the wine bottle and takes it away from the step-by-step circular conveyor line (1.3); the wine bottle gripper (7.2.3.2) starts to rotate after being lifted to a certain height, rotates the wine bottle to a posture perpendicular to the horizontal plane, and then follows the gripper to fall at a designated position (set as the input conveyor line of the external equipment used for the next step on site), the wine bottle gripper (7.2.3.2) unfolds, and the wine bottle falls vertically at the designated position, and then the wine bottle gripper (7.2.3.2) returns to the starting point, and the cycle repeats.

[0019] The technical features of the present invention are as follows: The conventional wine bottle labeling process includes bottle loading, label removal, labeling, moisture cleaning, label paper fixing, and bottle unloading. Through the process flow of this equipment, all unmanned operations can be achieved. While ensuring the output rate of finished products, the number of processing personnel is greatly reduced, the employment standards and labor input are reduced, and production expenses are saved; In the large label scraping mechanism (4), the outer contour of the customized wine bottle contour plate (4.5) is reversely drawn according to the contour of the wine bottle to be labeled, and in conjunction with the scraper frame (4.7.4) that can float up and down, the large label center scraper (4.7.5) and the large label edge scraper (4.7.6) can move closely to the edge of the wine bottle to complete the scraping operation; Customized wine bottle contour plates (4.5) and all scrapers support quick-release replacement. Contour plates and scrapers of different shapes can be drawn and processed according to the outer contours of different wine bottles to meet different wine bottle labeling requirements. Similarly, the equipment process can also be used for standard cylindrical bottle labeling, with a high degree of flexibility. The step-type circular conveyor line (1.3) can be selected to any length according to actual needs, so the large label labeling mechanism (3), large label wiper mechanism (4), round label labeling mechanism (5), and round label wiper mechanism (6) in the equipment can be set in plural, which is convenient for increasing the labeling output; The bottle unloading mechanism (7) simulates the manual unloading process, and the grabbed wine bottle can be placed upright and removed from the device. Therefore, it does not need to configure additional switching equipment or modification solutions to connect with the existing processing line on site, and has a high degree of flexibility.
