Description

Technical Field

[0001] The utility model relates to the technical field of glass product processing, in particular to a glass bottle unloading device. Background Art

[0002] In the production process of glass bottles, the formed glass bottles need to be taken out from the forming mold and transferred to the next process. Currently, this process mainly relies on the use of automated equipment such as manipulators. However, there are the following deficiencies in using a manipulator for unloading:

[0003] • High equipment cost: Using a manipulator as an unloading tool will significantly increase the initial investment of the enterprise.

[0004] • Complex maintenance: The maintenance of a manipulator is usually complex and requires professional technicians to perform maintenance and servicing regularly. Content of the Utility Model

[0005] The utility model aims to provide a glass bottle unloading device, which aims to simplify the structure, thereby reducing the use and maintenance costs of the glass bottle unloading device and improving the economy and practicability of the device.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A glass bottle unloading device, including a frame, a turntable and an unloading part. The turntable is rotatably arranged on the frame. There are several stations for forming glass bottles on the turntable. Each station includes a preform forming unit, a transfer blowing mechanism and a forming unit from top to bottom. The glass raw material is fixedly clamped on a holder and is formed into a glass bottle through the preform forming unit and the forming unit in sequence. The unloading part is fixedly arranged on the frame and can unload the glass bottle clamped by the holder.

[0007] The beneficial effects of this scheme are as follows: 1. By utilizing the force of the rotation of the turntable in cooperation with the slope, the smooth and efficient unloading of the formed glass bottles is realized, thereby improving the production efficiency and product quality; 2. By simplifying the equipment structure, the complexity of the equipment is reduced, making the use and maintenance of the equipment simpler, and reducing the initial investment and subsequent maintenance costs of the enterprise; 3. By simplifying the structure, the use cost and maintenance cost of the equipment are reduced, the economy and practicability of the equipment are improved, and it can better meet the needs of the modern glass product processing industry.

[0008] Furthermore, the entire discharging part is an arc-shaped plate coaxial with the turntable. A slope that gradually rises in the rotating direction of the turntable is provided at the top of the arc-shaped plate; the gripper includes a clamping unit and an opening / closing unit. The clamping unit includes two symmetrically arranged gripper bodies. The two ends of each gripper body are respectively a driving end and a clamping end, and the middle part is hinged to the core shaft; the opening / closing unit includes an opening / closing rod. An installation groove is provided on the housing. One end of the opening / closing rod is hinged in the installation groove, and the other end can move on the slope and control the opening / closing action of the driving end.

[0009] Furthermore, the opening / closing unit further includes an opening / closing plate, a first opening / closing member, and a second opening / closing member; the opening / closing plate is slidably arranged on the core shaft and abuts against the opening / closing rod. Both the first opening / closing member and the second opening / closing member include a cylinder body and a piston rod. The piston rod divides the cylinder body into a rod chamber and a rodless chamber. The rodless chambers of the first opening / closing member and the second opening / closing member are communicated. The free ends of the cylinder body and the piston rod of the first opening / closing member are respectively hinged to the driving end. The cylinder body of the second opening / closing member is fixedly arranged on the core shaft, and the free end of the piston rod of the second opening / closing member is fixedly connected to the opening / closing plate. During the production process of glass bottles, it is necessary to spray cooling water or demolding agent, and the humidity at the production site is relatively high. At the same time, the molten glass continuously radiates heat outward, making the temperature at the site relatively high. In a high-temperature and high-humidity environment, the damage to electronic components is relatively large. In this application, through the combination of pneumatic components and mechanical structures, the opening / closing of the gripper is controlled. By setting a corresponding discharging part on the rack and linking the discharging part with the opening / closing unit, the force of the turntable rotation is borrowed to complete the discharging, reducing the use of electronic equipment and lowering the maintenance cost.

[0010] Furthermore, the clamping unit further includes a connecting member and a guiding member. One end of the connecting member is fixedly connected to the gripper body, and the other end is hinged to the guiding member. The guiding member is slidably arranged on the core shaft. Through the arrangement of the guiding member and the connecting member, the opening / closing angles of the two gripper bodies are the same, improving the controllability of the gripper.

[0011] Furthermore, a tension spring is fixed between the opening / closing plate and the core shaft. Under the action of the tension spring, the second opening / closing member is in a contracted state, and the first opening / closing member is in an extended state, making the clamping state of the clamping end of the gripper stable and avoiding loosening during operation, which affects the forming quality of the glass bottle.

[0012] Furthermore, both the first opening / closing member and the second opening / closing member are gas springs, and the diameter of the second opening / closing member is larger than that of the first opening / closing member. The larger diameter of the second opening / closing member means that the second opening / closing member can drive the first opening / closing member to contract a longer distance by extending a shorter distance, thus quickly completing the opening / closing work of the gripper and improving work efficiency.

[0020] Embodiment 1

[0021] Embodiment 1 is basically as shown in the attached Figures 1-5 shown. As Figures 1-5 shown, the glass bottle discharging device includes a frame, a discharging part 12 and a turntable. As Figure 2 shown, the discharging part 12 is an arc-shaped plate coaxial with the turntable as a whole. A slope 121 gradually rising in the rotating direction of the turntable is arranged at the top of the arc-shaped plate, and a notch is arranged below the arc-shaped plate, and the notch forms a discharging position 122 for taking out the glass bottle.

[0022] The turntable is rotatably arranged on the frame. A plurality of working stations 2 for forming glass bottles are arranged on the turntable. Each working station 2 includes a prototype forming unit 22, a transfer and blowing mechanism 23 and a forming unit 22 from top to bottom. The discharging part 12 is fixedly arranged on the frame and can discharge the glass bottle clamped by the gripper.

[0023] As shown Figure 1 in the figure, the turntable includes an upper turntable 111, a middle turntable 112 and a lower turntable 113 from top to bottom. The upper turntable 111, the middle turntable 112 and the lower turntable 113 can be an integral body or three relatively independent structures. In this embodiment, the upper turntable 111, the middle turntable 112 and the lower turntable 113 are independent structures. The upper turntable 111, the middle turntable 112 and the lower turntable 113 are all rotatably arranged on the frame. The feeding unit 21, the transfer and blowing mechanism 23 and the forming unit 22 are respectively arranged on the upper turntable 111, the middle turntable 112 and the lower turntable 113. During use, the upper turntable 111, the middle turntable 112 and the lower turntable 113 rotate at the same angular velocity to ensure that the relative positions of the feeding unit 21, the transfer and blowing mechanism 23 and the forming unit 22 in the same station 2 remain fixed. When the equipment installed on the upper turntable 111, the middle turntable 112 or the lower turntable 113 needs to be overhauled, the upper turntable 111, the middle turntable 112 and the lower turntable 113 can be misaligned to leave an operating space for convenient overhaul.

[0024] The feeding unit 21 includes two groups of prototype die bodies 211 and prototype die opening and closing driving parts 212. The prototype die body 211 has a semi-cylindrical structure. The two groups of prototype die bodies 211 are combined to form a prototype die. A prototype die rotating part 2112 and a prototype die hinged part 2113 are welded on the prototype die body 211. A first sealing section is welded or integrally formed at the lower end of the prototype die. In this embodiment, the first sealing section is integrally formed with the prototype die body 211. An air inlet hole 2111 is arranged on the side wall of the first sealing section. The prototype die rotating part 2112 is rotatably connected to the frame. The prototype die opening and closing driving part 212 is a telescopic driving part such as an oil cylinder or a cylinder. In this embodiment, the prototype die opening and closing driving part 212 is a cylinder. The cylinder block of the cylinder is hinged to the frame, and the output device of the cylinder is hinged to the prototype die hinged part 2113. Thus, through the expansion and contraction of the prototype die opening and closing driving part 212, the prototype die body 211 is driven to rotate around the connection point where the prototype die rotating part 2112 is rotatably connected to the frame, and the opening and closing of the prototype die is completed. The air inlet hole 2111 is connected to compressed air.

[0025] The transfer and blowing mechanism 23 includes a housing 231, a rotating unit, a blowing unit and a clamping and opening and closing unit. As Figure 5 shown in the figure, an installation groove 2312 is arranged on the side wall of the housing 231. Shafts 2311 are welded on both sides of the housing 231. The shafts 2311 are rotatably arranged on the middle turntable 112 and drive the housing 231 to rotate in the vertical direction through the rotating unit. A sealing part 2313 is bonded to the upper end of the housing 231.

[0026] As Figure 3As shown in the figure, the rotating unit includes a rotating motor 2372 and a driven bevel gear 2371. The rotating motor 2372 is fixed to the middle turntable 112 by bolts, and a driving bevel gear meshing with the driven bevel gear 2371 is key-connected to the output shaft. The driven bevel gear 2371 is key-connected to the rotating shaft 2311. The rotating motor 2372 is a servo motor. During use, the driving bevel gear is driven to rotate by the rotating motor 2372, and the rotating shaft 2311 is driven to rotate by the driving bevel gear, so as to drive the housing 231 to rotate in the vertical direction.

[0027] The blowing unit includes a mandrel 232 and an end cap 236. The mandrel 232 is fixedly arranged inside the housing 231, and the end cap 236 is threadedly connected to the upper end of the mandrel 232. A rotating seal 235 is arranged between the housing 231 and the mandrel 232. The rotating seal 235 is bonded to the mandrel 232 and fits against the inner wall of the housing 231.

[0028] The clamping and opening / closing unit includes a clamp and an opening / closing unit. The clamp includes a clamp body 2341, a connecting member 2346 and a guiding member 2342 as shown in Figure 4 the figure. The clamp body 2341 includes a driving end and a clamping end. The middle of the clamp body 2341 is hinged to the connecting portion 2321, and the two ends are respectively the driving end and the clamping end. During use, the clamping end is driven to open and close by applying force to the driving end. When the clamping ends are closed, the inner sides of the clamping ends and the outer sides of the air outlets jointly form a flash forming cavity. The upper end of the connecting member 2346 is welded to the clamp body 2341, and the lower end is hinged to the guiding member 2342. The guiding member 2342 is slidably arranged on the mandrel 232, so as to ensure that the opening and closing angles of the clamp body 2341 are the same through the limitation of the guiding member 2342.

[0029] As shown in Figure 5As shown in the figure, the opening and closing unit includes an opening and closing plate 2343, an opening and closing rod 233, a first opening and closing member 2344, and a second opening and closing member 2345. The opening and closing plate 2343 is slidably arranged on the core shaft 232. A tension spring (not shown in the figure) is also welded or bolted between the core shaft 232 and the opening and closing plate 2343. The axis of the tension spring is parallel to the axis of the core shaft 232. The opening and closing rod 233 is rotatably arranged in the installation groove 2312. Both the first opening and closing member 2344 and the second opening and closing member 2345 are telescopic members such as cylinders, oil cylinders, or gas springs. In this embodiment, both the first opening and closing member 2344 and the second opening and closing member 2345 are gas springs. The gas spring includes a spring body and a piston rod. The piston rod is slidably arranged in the spring body and divides the spring body into a rod chamber and a rodless chamber. When the volume of the rodless chamber increases, the gas spring extends. The free ends of the spring body and the piston rod of the first opening and closing member 2344 are respectively hinged to the driving end of the gripper body 2341. The spring body of the second opening and closing member 2345 is bolted to the core shaft 232, and the free end of the piston rod is welded to the opening and closing plate 2343. The rodless chambers of the first opening and closing member 2344 and the second opening and closing member 2345 are in series. Under the action of the tension spring, the second opening and closing member 2345 is in a contracted state. When the second opening and closing member 2345 contracts, the first opening and closing member 2344 extends. The diameter of the piston rod of the second opening and closing member 2345 is larger than the diameter of the piston rod of the first opening and closing member 2344, so as to ensure that when the second opening and closing member 2345 extends and contracts a shorter distance, the first opening and closing member 2344 can extend and contract a larger distance.

[0030] The forming unit 22 includes a forming die, such as Figure 3 As shown in the figure, the forming die includes a side die 221 and a bottom die 222. A side die rotating part 2211 and a side die hinged part 2212 are welded to the outer side of the side die 221 body. The side die rotating part 2211 is rotatably connected to the frame. The side die hinged part 2212 is hinged with a side die opening and closing driving member 223. The side die opening and closing driving member 223 is a telescopic driving member such as an oil cylinder or a cylinder. In this embodiment, the side die opening and closing driving member 223 is a cylinder. The cylinder body of the cylinder is hinged to the frame, and the output device of the cylinder is hinged to the side die hinged part 2212. Thus, through the extension and contraction of the side die opening and closing driving member 223, the side die 221 body is driven to rotate around the connection point where the side die rotating part 2211 is rotatably connected to the frame, completing the opening and closing work of the side die 221. A second sealing section 2213 is arranged at the upper part of the side die 221. A sealing part 2313 is fixed to the upper end of the housing 231. A rotating seal is arranged between the core shaft 232 and the housing 231. When the transfer and blowing mechanism 23 is in an inverted state, the end cover 236 and the sealing part 2313 are both located in the second sealing section 2213; a lifting driving member is fixed to the lower end of the bottom die 222. In this embodiment, the lifting driving member is a cylinder. The cylinder body of the cylinder is bolted to the frame, and the output shaft is welded or bolted to the bottom die 222.

[0031] During use, as Figure 1As shown, the lower end of the push rod moves from one end of the slope 121 to the other end, causing the front end of the push rod to rotate downward. By pushing the opening and closing plate 2343 downward through the opening and closing part 2331, the piston rod of the first opening and closing part 2344 is driven to move downward, and then the volume of the rodless cavity of the first opening and closing part 2344 becomes larger. Since the rodless cavities of the first opening and closing part 2344 and the second opening and closing part 2345 are in series, the increase in the volume of the rodless cavity of the first opening and closing part 2344 will necessarily drive the volume of the rodless cavity of the second opening and closing part 2345 to become smaller, so that the upper ends of the gripper body 2341 approach each other and the lower ends move away from each other, and then the lower end of the gripper body 2341 opens, facilitating the removal of the formed glass bottle.

[0032] The specific implementation process is as follows:

[0033] The glass raw material falls from the feed pipe 11 and enters the prototype mold through the flared opening at the upper end of the prototype mold. Part of the glass raw material flows into the flash forming cavity formed by the gap between the mandrel 232 and the gripper body 2341, hardens to form the flash 31, and is clamped between the gripper body 2341 and the mandrel 232. The remaining part forms a cylinder under the action of the gravity of the glass raw material itself and the restriction of the prototype mold. At the same time, station 2 moves away from the feed pipe 11 driven by the turntable, and the surface of the glass raw material in contact with the prototype mold solidifies due to heat loss, obtaining the glass bottle prototype.

[0034] Subsequently, under the action of the rotation unit, the transfer and blowing mechanism 23 rotates to the vertical state, so that the glass bottle prototype enters the forming mold, and the prototype mold and the forming mold are closed, and the upper and lower ends of the transfer and blowing mechanism 23 are clamped.

[0035] After that, when the prototype mold and the forming mold are closed and the clamping of the upper and lower ends is completed, compressed air enters the end cover 236 through the intake part 2361 from the intake hole 2111 and blows and forms the glass bottle prototype through the through hole.

[0036] Finally, when the glass bottle is hardened, station 2 reaches the unloading part 12 under the action of the turntable, and the transfer and blowing mechanism 23 rotates 15 - 90°, so that the roller is lifted onto the slope. By using the roller to roll on the slope, the opening and closing rod 233 is driven to rotate, so that the opening and closing part 2331 changes from an inclined state to a vertical state, pushes the opening and closing plate 2343 to slide downward on the mandrel 232, drives the second opening and closing part 2345 to extend, and then drives the first opening and closing part 2344 to contract, so that the lower end of the gripper body 2341 expands, releases the clamping of the flash 31, and takes out the formed glass bottle from the discharge position 122, completing the unloading work of the formed glass bottle. After the unloading is completed, under the action of the tension spring, the opening and closing plate 2343 resets, thereby driving the second opening and closing part 2345 to reset, and then driving the gripper body 2341 to reset.

[0037] The above are only the embodiments of the present utility model, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that the technical means for solving problems in the above embodiments of the present utility model can be used in combination to solve multiple technical problems simultaneously. For those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
