Description

Technical Field

[0001] The invention belongs to the mechanical field and relates to a container production line, in particular to a continuous production line for a jar body or a cylinder body. Background Art

[0002] When producing an altar body or a cylinder body, a mold is used to make a blank, and then the mold is demoulded and the blank is dried and baked.

[0003] The traditional method uses a plaster mold to make a blank. After the blank is rolled into a plaster mold using a rolling forming machine, the blank needs to be placed in the plaster mold for a long time because it contains a certain amount of moisture. Only then can the blank reach a suitable hardness and then be demolded from the plaster mold to obtain a qualified blank. The production efficiency is low, and since the plaster mold needs to be left stationary, a large number of plaster molds are required, which will cause the accumulation of plaster molds and occupy factory area.

[0004] In order to improve production efficiency, a high-pressure mold is now used to make a green body. After the green body is added to the high-pressure mold for roll forming, the green body in the high-pressure mold is inflated and pressurized to squeeze out the moisture in the green body. The squeezed moisture is absorbed by the high-pressure mold, which accelerates the water loss and solidification rate of the green body. Then, the green body is obtained after the mold is demolded, which improves the production efficiency of the green body. In order to facilitate demolding of the mold, the high-pressure mold is now designed as a split structure. The various parts are assembled to form the main body of the mold. After splitting, the green body can be demolded.

[0005] The opening of the cylinder container is usually a wide-mouth structure, and its mold usually includes an upper mold and a bottom mold. After the upper mold and the bottom mold are assembled, clay is loaded, and then the mold is put into a rolling machine for one-time rolling forming. Finally, the upper mold and the bottom mold are separated, and the blank can be taken out. The opening of the altar container is usually closed, and its mold usually includes an upper mold, an intermediate mold and a bottom mold. It cannot be rolled in a rolling machine at one time, and it needs to be rolled separately. Generally, the upper half of the blank is rolled on the upper mold, and the lower half of the blank is rolled after the intermediate mold and the bottom mold are locked, and the upper mold is inverted and rolled in the rolling machine. After the various parts of the blank are obtained, the mold is assembled, and the blank is bonded to the body to obtain a complete blank. In addition, in order to support the mold, the bottom mold is usually locked with the upper mold of the cylinder or the intermediate mold of the altar to ensure safety in use. The bottom mold and the upper mold or the intermediate mold are locked with the help of a hook, which is set on the upper mold or the intermediate mold. After the hook is hung with the hanging point on the bottom mold, locking is achieved. In order to prevent the hook from being untied at will, a shielding ring is usually provided outside the hook. After the shielding ring is pushed away from the hook, the hook can be untied, and the hook can be automatically unlocked after the shielding ring is pushed away from the hook by adding elastic components such as torsion springs, thereby ensuring flexibility of use.

[0006] In summary, the production process of the jar body or cylinder body is complicated. Although some improvements have been made in the existing technology, there are still problems such as poor automation level, unreasonable distribution of various production processes, and separate production lines for the jar body or cylinder body. The blank needs to consume a lot of time in rolling forming and demolding and transportation, and the production efficiency is low. Summary of the invention

[0007] In order to solve the problems of poor automation level of roll forming, demoulding and transportation, low production efficiency, high cost and low production line utilization rate of separate production lines for jar bodies or cylinder bodies, the present invention provides a continuous production line for jar bodies or cylinder bodies. The blank making line and the demoulding line are built by relying on blank making hoisting brackets and demoulding hoisting brackets. One production line can produce both jar bodies and cylinder bodies, and blank making and demoulding can be carried out continuously, with high automation level, reasonable space utilization and high production efficiency.

[0008] The technical solution adopted by the present invention is: to provide a continuous production line for a jar body or a cylinder body, comprising a blank making line, a demoulding line and a blank making and demoulding connection transmission structure; the blank making line comprises a blank making hoisting bracket, a first roll forming machine, a second roll forming machine, a mold placing table arranged in sequence under the blank making hoisting bracket, and a flip hoisting structure and a first transport hoisting structure slidably arranged on the blank making hoisting bracket; the demoulding line comprises a demoulding hoisting bracket parallel to the blank making hoisting bracket, a blank placing table arranged under the demoulding hoisting bracket and a second transport hoisting structure slidably arranged on the demoulding hoisting bracket; the blank making and demoulding connection transmission structure comprises a mold main handling conveying mechanism, a mold auxiliary handling conveying mechanism and a mold blank integral conveying unit extending from under the blank making hoisting bracket to under the demoulding hoisting bracket, a blank picking and placing device arranged between the first roll forming machine and the second roll forming machine, and a blank removing device arranged on one side of the blank placing table; a bottom mold handling structure is arranged on the mold main handling conveying mechanism, and a pressurizing and consolidating mechanism is arranged on each mold blank integral conveyor.

[0009] The production line consists of a blank making line and a demoulding line, which are built on the basis of a blank making hoisting bracket and a demoulding hoisting bracket. When producing a jar body blank, the upper mold of the mold needs to be rolled separately, and the middle mold and the bottom mold of the mold are rolled after being locked in combination. The flip hoisting structure flips the upper mold of the jar body mold upside down in the first roll-forming machine, and the first transport hoisting structure hoists the locked middle mold and the bottom mold of the jar body into the second roll-forming machine. When producing a cylinder body blank, it is only necessary to roll the locked upper mold and the bottom mold, and hoist them into the second roll-forming machine through the first transport hoisting structure. Rolling is sufficient. After rolling forming, the upper mold of the jar body is flipped and flipped by the flip hoisting structure and then hoisted onto the middle mold, so that the jar blank is bonded and formed, and the mold is hoisted onto the mold placement table, the blank is trimmed, and then the formed mold is hoisted onto the mold blank integral conveyor. The cylinder body blank can be directly hoisted onto the mold blank integral conveyor by the first transport hoisting structure, and transported to the pressurizing and consolidating mechanism to pressurize and consolidate the blank in the mold, so that the moisture in the blank is squeezed out and absorbed by the mold, and the pressurizing and consolidating mechanism presses the mold tightly to avoid mold separation and air leakage that cause damage to the blank, and the mold is pressurized. After consolidation, it is transported to the bottom of the demoulding lifting bracket and lifted forward by the second transport and lifting structure along the demoulding lifting bracket to the main mold handling conveying mechanism. The altar mold first performs demoulding of the upper mold on the main mold handling conveying mechanism, and then demoulding of the bottom mold. The cylinder mold first performs demoulding of the bottom mold on the main mold handling conveying mechanism. When demoulding the upper mold of the altar mold, the second transport and lifting structure directly clamps and lifts the upper mold, and transfers it to the mold auxiliary handling conveying mechanism, and transports it back to the bottom of the blank making lifting bracket for smooth use. The bottom mold handling structure on the second transport and lifting structure is released. After the bottom mold is locked, the second transport and hoisting structure hoists the middle mold of the altar mold or the upper mold of the cylinder mold onto the blank placement table, and then the second transport and hoisting structure pushes the middle mold of the altar mold or the upper mold of the cylinder mold to move downward along the blank to take it off and complete the demolding operation. After the complete altar blank or cylinder blank is removed, the second transport and hoisting structure hoists the middle mold of the altar mold or the upper mold of the cylinder mold to re-combine it with the bottom mold, and after locking it using the bottom mold handling structure, it is transported back to the blank making line by the mold main handling conveying mechanism to continue the blank making operation, thereby improving the degree of automation and improving production efficiency.

[0010] To further optimize the technical solution, the blank picking and placing equipment and the blank moving equipment are both arranged between the blank making lifting bracket and the demoulding lifting bracket.

[0011] The blank picking and placing equipment and the blank moving equipment enhance the automation of the production line, and the two are arranged between the blank making hoisting bracket and the demoulding hoisting bracket, which improves the space utilization and makes the production line more compact.

[0012] To further optimize the technical solution, the blank picking and placing equipment includes a blank storage table, and a grabbing robot arm is set up on one side of the blank storage table.

[0013] The blanks are picked up and placed by the grabbing robot arm, which improves the degree of automation, is flexible to use, and ensures production efficiency To further optimize the technical solution, the blank removal equipment includes a horizontal base frame, a rotating base is slidably arranged on the horizontal base frame, a support frame is vertically arranged on the rotating base, a connecting seat is vertically raised and lowered on the support frame, and a transport assembly is arranged on the connecting seat; the transport assembly includes support arms distributed on both sides of the connecting seat, the support arms are arranged on the connecting seat for relative reciprocating movement with the help of a linear drive assembly, and an arc-shaped support plate is fixedly installed on the inner side of the support arms.

[0014] By adjusting the position and height of the pallet, it is placed under the tray supporting the blank, and then the tray is lifted to transport the blank. The rotating base moves and rotates along the horizontal base frame to transport the blank out of the production line. The structure is simple, stable and flexible to use. To further optimize the technical solution, the flipping hoisting structure, the first transporting hoisting structure and the second transporting hoisting structure all include a crane that is slidably arranged with the blank making hoisting bracket and the demoulding hoisting bracket, and the bottom of the crane is equipped with a lifting bracket, and the lifting bracket is respectively equipped with a flipping hoist and a transporting hoist.

[0015] The mould is hoisted by the crane through the bracket equipped with the turning hoist and the transport hoist, and the crane moves along the blank making hoisting bracket and the demoulding hoisting bracket to transport the mould. The structure is simple and the use is stable and reliable.

[0016] To further optimize the technical solution, the flip sling includes a ring rotatably arranged in the lifting bracket, and the ring is composed of two arms arranged to open and close; the transport sling includes two supporting arms arranged axially symmetrically, and the supporting arms are respectively arranged on the lifting bracket for linear movement by means of linear drive components.

[0017] The holding ring is rotatably assembled in the bracket. After the holding arms that are opened and closed on the holding ring hold the mold tightly, they rotate along the bracket to adjust the position of the mold. The operation is simple and flexible. The linear drive component drives the supporting arms to move linearly on the bracket, so that the two symmetrically arranged supporting arms approach and separate from each other. After the supporting arms approach each other, they hold the mold tightly and abut against the outer convex edges on the mold, thereby lifting the mold and facilitating demoulding. After the supporting arms separate from each other, the lifting of the mold is released. The use is flexible.

[0018] To further optimize the technical solution, the pressurizing and consolidating mechanism includes a vertically arranged frame, the frame is mounted on the mold blank integral conveyor, and a clamping plate is arranged in the frame for lifting and lowering, an air channel is arranged on the clamping plate, and the air channel is connected to an air source.

[0019] After the mold is transported to the frame, the mold is pressed down by the clamping plate to move the frame, thereby applying pressure to the bottom of the mold, and the mold is compacted and consolidated in turn. The mold is then inflated and pressurized to squeeze out the moisture in the blank and absorb it into the mold. The mold is compacted and consolidated to avoid damage to the blank caused by mold separation and air leakage, thereby ensuring safety in use.

[0020] To further optimize the technical solution, the bottom mold handling structure includes at least two demoulding brackets mounted on the mold main handling and conveying mechanism, the demoulding brackets are relatively arranged on the mold main handling and conveying mechanism, and the demoulding brackets are both provided with push plates and articulated seats for lifting and lowering, and claws are hinged on the articulated seats for rotation by means of a driving member.

[0021] The push plate is adjusted to contact the lower end surface of the shielding ring. The push plate pushes the shielding ring upward. After the shielding ring is removed from the hook, the hook loses its constraint, thereby releasing the lock on the bottom mold so that the bottom mold can be demoulded. After the demoulding operation is completed, the middle mold of the jar body or the upper mold of the cylinder body is re-lifted onto the bottom mold, and the claw is rotated to a horizontal position along the hinge seat so that it abuts against the upper end surface of the shielding ring, and then the hinge seat is pulled downward to cover the shielding ring on the hook again, so that the hook can re-lock the bottom mold so that it can be transported back to the blank making line for blank making operations to ensure production efficiency.

[0022] The continuous production process of the jar body based on the above production line includes the following process steps: S1. Combine the middle mold and the bottom mold: The bottom mold processing structure on the mold main processing and transmission mechanism combines and locks the middle mold and the bottom mold of the jar body mold; S2, lower blank forming: the combined middle mold and bottom mold are transported to the bottom of the blank making hoisting bracket by the mold main handling conveying mechanism, and after the blank picking and placing device puts the blank into the combination of the middle mold and the bottom mold, the first handling and hoisting structure hoists it into the second roll forming machine for lower blank forming; S3, upper blank forming: the upper die of the jar body is lifted by the inverted lifting structure, and is turned upside down in the first roll forming machine, and the blank picking and placing device puts the blank into the inverted upper die, and then the upper blank is formed; S4, combining the upper blank and the lower blank: turning over the upper blank jar body and the upper mold hoisted by the hoisting structure, turning over again and placing them on the combined middle mold, bottom mold and lower blank to form a mold blank of the jar blank plus the combined mold; S5.

The second transport hoisting structure demoulds the upper mold of the assembled mold and hoists the upper mold to the mold auxiliary disposal conveying mechanism; S8, removing the middle mold and the bottom mold: the bottom mold handling structure on the mold main handling and conveying mechanism releases the locking of the middle mold and the bottom mold, and the second handling and hoisting structure hoists the middle mold, so that the altar blank and the middle mold are separated from the bottom mold and then placed on the blank placement table; the second handling and hoisting structure pushes the middle mold downward to the side of the blank placement table, and the altar blank is separated from the middle mold; S9, altar body removal: the altar body removal equipment moves the altar body away from the body placement table; S10, the middle mold and the bottom mold are combined and returned to their positions: the second transport and hoisting structure hoists the middle mold onto the mold main handling and conveying mechanism, and docks it with the bottom mold, and uses the bottom mold handling structure to lock the middle mold and the bottom mold, and the mold main handling and conveying mechanism transports the locked middle mold and the bottom mold back to the bottom of the blank making hoisting bracket; S11, upper mold return: the mold auxiliary handling conveying mechanism transports the demoulding upper mold back to the bottom of the blank making lifting bracket.

When making a cylinder blank, the mold of the cylinder body is composed of an upper mold and a bottom mold. When rolling, the upper mold and the bottom mold are butted and locked, and the combined cylinder mold is placed in the mold sleeve 502 of the second rolling machine 51, and then the mold sleeve 502 moves to the bottom of the rolling head 501. After the rolling head 501 moves down into the mold, the blank in the mold is rolled, and then the mold is moved to the bottom of the blank making hoisting bracket 1, so that it can be hoisted and transported by the carrying hanger 401; When making the altar body, the mold of the altar body is composed of an upper mold, an intermediate mold and a bottom mold. When rolling, the upper mold needs to be rolled separately, and the combined structure of the intermediate mold and the bottom mold needs to be rolled. When rolling the upper mold, the flip hanger 301 on the flip hoisting structure 3 needs to be flipped to hang the upper mold, and the upper mold is flipped and inverted in the mold sleeve 502 of the first roll forming machine 5. The mold sleeve 502 blocks the opening of the upper mold, and the combined structure of the intermediate mold and the bottom mold is rolled by The first transport and hoisting structure 4 is hoisted into the die sleeve 502 of the second roll-forming machine 51, and then the die sleeve 502 moves the die to the bottom of the rolling head 501 respectively, and the rolling head 501 moves down into the die respectively, and rolls the blank in the die respectively, and then the die moves to the bottom of the blank making hoisting bracket 1 so that the flip hoist 301 and the transport hoist 401 can hoist it, and the flip hoist 301 lifts the upper die again and flips it so as to dock with the middle die and the bottom die; A mold placement table 6 is provided behind the rolling station. After the green body is made in the mold, especially after the jar body mold is made, since the upper mold, the middle mold and the bottom mold of the jar body are rolled separately and then butt-jointed to form, they need to be hoisted onto the mold placement table 6, and the bonding position of the green body is trimmed. After the trimming is completed, it is hoisted by a transport hoist 401 to the mold green body integral conveyor 9 behind the mold placement table 6 for transportation; The mold blank integral conveyor 9 is arranged below the blank making hoisting bracket 1 and extends to below the demoulding hoisting bracket 2. The mold blank integral conveyor 9 is formed by setting up a track between the blank making hoisting bracket 1 and the demoulding hoisting bracket 2. A traveling crane 14 runs on the track. After the mold is hoisted onto the traveling crane 14, it is transported to the demoulding hoisting bracket 2. During the transportation process of the mold blank integral conveyor 9, a pressurizing and consolidating mechanism 901 is centrally arranged on the mold blank integral conveyor 9.

The pressing plate 9012 is against the top surface of the upper mold. With the continuous pressure of the pressing plate 9012, the mold is pressed. An air channel is provided on the pressing plate 9012, and the air channel is connected to the air source, so that the wet blank of the mold is inflated and pressurized, so that the moisture in the blank is squeezed out and absorbed by the high-pressure mold, and the water loss and solidification rate of the blank is accelerated. At the same time, the pressing plate 9012 and the frame 9011 cooperate to press the mold, so as to avoid the mold separation and air leakage that cause the blank damage, and ensure the safety of use; After the mold is pressurized and consolidated, the mold blank integral conveyor 9 transfers the mold to the bottom of the demoulding hoisting bracket 2, and is hoisted and transported forward by the second handling hoisting structure 41 on the demoulding hoisting bracket 2. The mold sub-handling conveying mechanism 8 and the mold main handling conveying mechanism 7 are arranged from back to front under the demoulding hoisting bracket 2. The mold sub-handling conveying mechanism 8 and the mold main handling conveying mechanism 7 extend to the bottom of the blank making hoisting bracket 1 and are located between the first roll forming machine 5 and the second roll forming machine 51. The mold sub-handling conveying mechanism 8 and the mold main handling conveying mechanism 7 can be a track laid between the demoulding hoisting bracket 2 and the blank making hoisting bracket 1. A traveling crane 14 is also arranged on the track to transport the mold; When the jar mold is transported forward along the demoulding hoisting bracket 2 by the second transport hoisting structure 41, the transport hoist 401 hoists the middle mold. The locking of the middle mold and the bottom mold and the support of the upper mold make the hoisting stable and reliable. When the cylinder mold is transported and hoisted, the transport hoist 401 hoists the upper mold. The locking of the upper mold and the bottom mold also makes the hoisting stable. The hoisted molds will pass over the mold auxiliary disposal conveying mechanism 8 and be placed on the mold main disposal conveying mechanism 7. When demoulding the jar body mold, the transport hanger 401 on the second transport and hoisting structure 41 is adjusted to the side of the upper mold, and the support arm 4011 on the transport hanger 401 is synchronously close to the upper mold and abuts against the outer convex edge of the upper mold. Then, the transport hanger 401 moves upward to lift the upper mold, and then the transport hanger 401 moves backward to place the upper mold on the mold auxiliary disposal conveying mechanism 8 and transfer it to the bottom of the blank making hoisting bracket 1. Then, after the upper mold is re-hoisted by the flip hanger 301, it is flipped upside down in the mold sleeve 502 of the first roll forming machine 5 to make blanks again, which is smooth and flexible to use. After the upper mold on the jar mold is demoulded, the bottom mold is demoulded, and after the cylinder mold is placed on the mold main disposal and conveying mechanism 7, the bottom mold is first demoulded. The mold main disposal and conveying mechanism 7 is equipped with a bottom mold disposal structure 12, and the bottom mold disposal structure 12 is located below the demoulding hanging bracket 2. The bottom mold disposal structure 12 includes at least two demoulding mold assemblies, which are relatively arranged on the mold main disposal and conveying mechanism 7. The demoulding mold assembly includes a demoulding bracket 1201 fixedly installed on the outer wall of the mold main disposal and conveying mechanism 7, and the demoulding bracket 1 A push plate 1202 and an articulated seat 1203 are provided on 201 for lifting and lowering by means of a linear drive assembly (such as a telescopic cylinder, etc.). When removing the bottom mold, the push plate 1202 is driven to move upward to abut against the lower end surface of the shielding ring outside the mold, and then the push plate 1202 pushes the shielding ring to move upward along the middle mold or the upper mold of the cylinder mold, so that the hook in the shielding ring loses its constraint, so as to release the locking state between the bottom mold and the middle mold or the bottom mold and the upper mold of the cylinder mold, and then the middle mold of the altar mold or the upper mold of the cylinder mold is lifted again by means of the second transport and hoisting structure 41; After the middle mold of the altar mold or the upper mold of the cylinder mold is lifted, the bottom mold is separated from it, and the second transport and hoisting structure 41 transports it forward along the demoulding hoisting bracket 2. The front of the mold main handling conveying mechanism 7 supports a blank placement table 11, so that the blank and the remaining mold components are placed on the blank placement table 11, and then the transport hoist 401 clamps the middle mold of the altar mold or the upper mold of the cylinder mold, and moves downward along the blank. Since both the altar and the cylinder are structures with a wide top and a narrow bottom, the middle mold of the altar mold or the upper mold of the cylinder mold can be moved downward along the blank for demoulding, and the operation is smooth and flexible to use. A blank moving device 13 is provided on one side of the blank placing platform 11. The blank moving device 13 can be arranged between the blank making hoisting bracket 1 and the demoulding hoisting bracket 2 to optimize the spatial layout of the production line. The blank moving device 13 includes a horizontal base frame 1301, a rotating base 1302 is slidably arranged on the horizontal base frame 1301, a support frame 1303 is mounted on the rotating base 1302, a connecting seat 1304 is lifted and lowered on the support frame 1303, and a transport component is assembled on the connecting seat 1304. The transport component includes support arms 1305 distributed on both sides of the connecting seat 1304 on the left and right, and the support arms 1305 are arranged on the connecting seat 1304 for relative reciprocating movement by means of a linear driving component (such as a telescopic cylinder, etc.), and an arc-shaped supporting plate 1306 is fixedly installed on the inner side of the support arm 1305, and the blank is transported by the supporting plate 1306; When the blank is transported by the pallet 1306, when the blank is hoisted onto the blank placement platform 11, a pallet 15 is placed on the blank placement platform 11, and then the blank is placed on the pallet 15. When transporting it, the pallet 1306 is adjusted to the side of the pallet 15, and then the pallets 1306 are brought close to each other to be placed under the pallet 15. After the pallet 1306 moves upward, the pallet 15 and the blank are lifted upward, and then the rotating base 1302 is moved along the horizontal base frame 1301, and the blank is removed from the production line by a rotary motion, so that the blank can be processed in the next step. The transport assembly can also use a cloth bag to transport the blank. The transport assembly also includes an arm group arranged on the connecting seat 1304 from top to bottom. The arm group consists of two arc-shaped arms that are cross-rotated and hinged. The cloth bag can be a whole piece structure, and its upper and lower ends are respectively connected to the arms on the upper and lower sides. The cloth bag can also be cut into two axially symmetrical halves, and are respectively fixedly connected to the two arms distributed on the same side. When the blank is transported, the arms are opened and located around the blank, and then the arms are closed so that the cloth bag cover is arranged on the outside of the blank. After the connecting seat 1304 moves up along the support frame 1303, the cloth bag picks up the blank and then moves it out of the production line. The boom can be driven and hinged by means of the scissor brackets. The force arms on the scissor brackets are matched with the shape of the boom, thereby ensuring the assembly area of ​​the force arms and the boom, ensuring the assembly strength and reliability of use. At the same time, the scissor brackets are also driven by linear drive components (such as telescopic cylinders, etc.) to perform scissor movements, and the scissor brackets on the two booms can be driven to run synchronously by means of linkage components to ensure stability in use. The linkage shafts of the linkage components are arranged in parallel, and the linkage shafts are arranged between the two boom groups and are respectively hinged and assembled with the free ends of the force arms on the scissor brackets. The structure is simple and stable in use. After the blank is taken out from the blank placing table 11, the carrying hoist 401 hoists the middle mold of the altar body or the upper mold of the cylinder body to the mold main handling and conveying mechanism 7, and docks with the bottom mold. The demoulding bracket 1201 is hinged on the hinged seat 1203 which is lifted and lowered by a linear drive component (such as a telescopic cylinder, etc.), and the claw 1204 is also rotated on the hinged seat 1203 by the linear drive. After the middle mold of the altar body or the upper mold of the cylinder body is re-hoisted on the bottom mold, the claw 1204 is driven to rotate to a horizontal state and abuts against the upper end surface of the lifted shielding ring, and then the linear drive component (such as a telescopic cylinder, etc.) pulls down the shielding ring, locks the hook again, and covers the outside of the hook to restrict and protect it, and then the mold main handling and conveying mechanism 7 transports it to the bottom of the demoulding hoisting bracket 2 again, and after hoisting it into the mold sleeve 502 of the second roll forming machine 51, the rolling production is continued to ensure the smoothness of production; When the blank is added to the mold for rolling production, in order to improve the degree of automation of the production line, a blank picking and placing device 10 is assembled on one side of the rolling machine to put the blank into the mold. The blank picking and placing device 10 is also arranged between the blank making hoisting bracket 1 and the demoulding hoisting bracket 2, and can be arranged on one side of the first rolling forming machine 5. The blank picking and placing device 10 includes a blank storage table 1001, and the blanks are stacked on the blank storage table 1001. A grabbing robot arm 1002 is set up on one side of the blank storage table 1001. After the mold is hoisted into the mold sleeve 502, the grabbing robot arm 1002 grabs the blank on the blank storage table 1001, and after putting it into the mold, the rolling operation is performed to improve production efficiency. The working principle of the continuous production line of the jar body or cylinder body is as follows: the production line is composed of a blank making line and a demoulding line, and the blank making line and the demoulding line are built by relying on the blank making hoisting bracket 1 and the demoulding hoisting bracket 2. When producing the blank, the mold is first hoisted into the mold sleeve 502, and the grabbing mechanical arm 1002 grabs the blank on the blank storage table 1001 and puts it into the mold, and then performs rolling operation. Among them, when producing the jar body blank, it is necessary to roll the upper mold of the mold and the combination of the mold middle mold and the bottom mold to respectively roll the blank, and the middle mold and the bottom mold are locked and hoisted into the mold sleeve 502 of the second rolling forming machine 51, and the upper mold is flipped by the flip hanger 301 and inverted in the mold sleeve 502 of the first rolling forming machine 5. After the blank is roll-formed in each mold, the upper mold is flipped and hoisted on the combination of the middle mold and the bottom mold to bond the blank, and then the mold is hoisted onto the mold placement table 6 to trim the bonding part of the blank. The molded mold is hoisted onto the mold blank integral conveyor 9, and the mold is transported to the pressurizing and consolidating mechanism 901. After the mold is clamped and consolidated by the clamping plate 9012 and the outer frame 9011, the mold blank is inflated and pressurized to squeeze out the moisture in the blank and absorb it by the mold, thereby accelerating the dehydration and solidification rate of the blank, thereby pressurizing and consolidating the blank. At the same time, the clamping plate 9012 and the frame 9011 cooperate to press the mold to avoid mold separation and air leakage that cause damage to the blank, thereby ensuring safety in use. After the mold is pressurized and consolidated, it is transported to the bottom of the demoulding hoisting bracket 2, and is hoisted forward by the second transport hoisting structure 41 along the demoulding hoisting bracket 2 to the mold main disposal conveying mechanism 7. The altar mold first performs the demoulding work of the upper mold on the mold main disposal conveying mechanism 7, and then performs the demoulding work of the bottom mold. The cylinder mold first performs the demoulding work of the bottom mold on the mold main disposal conveying mechanism. When removing the upper mold of the altar mold, the transport sling 401 of the second transport and hoisting structure 41 can directly clamp and lift the upper mold, and transfer it to the mold auxiliary disposal conveying mechanism 8, and transport it back to the bottom of the blank making hoisting bracket 1. When removing the bottom mold, the push plate 1202 is driven to move upward, pushing the shielding ring upward to move out of the hook, and the hook loses its constraint and is bounced open by the elastic component, thereby releasing the lock of the bottom mold. Then the transport sling 401 re-lifts the middle mold of the altar mold or the upper mold of the cylinder mold, and places the middle mold of the altar mold or the upper mold of the cylinder mold and the complete blank on the blank placement table 11. Then the transport sling 401 pushes the middle mold of the altar mold or the upper mold of the cylinder mold to move downward along the blank, as to the side of the blank placement table 11, so as to remove the middle mold of the altar mold or the upper mold of the cylinder mold. Finally, the blank removal device 13 lifts the tray 15 supporting the blank by opening and closing the support arm 1305, moves along the horizontal base frame 1301 and makes a rotational motion, thereby removing the blank from the production line.After the blank is removed from the blank placement table 11, the transport hoist 401 re-lifts the middle mold of the jar body mold or the upper mold of the cylinder body mold onto the bottom mold, and then rotates the claw 1204 to a horizontal position and abuts against the upper end surface of the protective ring. By pulling the claw 1204 downward and pushing the protective ring downward, it is re-covered on the hook, and the bottom mold and the middle mold or the upper mold are re-locked to be transported back to the blank making line to continue the blank making operation, thereby reducing the amount of molds used, thereby reducing the area occupied by the molds, improving space utilization, and improving the degree of automation and production efficiency.
