Description

Technical Field

[0001] The invention relates to the technical field of plastic bottle production, in particular to a linear injection-blow-fill-seal integrated machine. Background Art

[0002] Plastic bottles are a common container with a huge demand and are widely used in a wide range of fields, such as food and beverage, medical containers, pharmaceutical containers, seasoning containers, etc. The production process of plastic bottles includes two-step method (commonly used in the early stage of industry development, that is, first make the bottles, then store the made bottles and wait for them to be taken out later according to needs, the preparation and use of the bottles are separated, that is, the two-step method) and one-step method (the preparation and use of the bottles are on the same production line).

[0003] In recent years, the one-step method has been increasingly recognized by the market. For example, the Chinese patent application number CN202210193687.X discloses a linear injection-blow-fill-seal integrated plastic bottle packaging device. Figure 1 As shown, a bottle receiving mechanism is provided which is composed of a transition slide rail 105, a transition mold 106, a lifting power device 107 and a horizontal power device 108, and an attached Figure 1 The lifting and lowering bottle-taking mechanism is not shown. When working, the bottle-receiving mechanism starts to move the transition mold 106 horizontally between the blank mold assembly 101 and the half mold 103. When the half mold 103 rises to a certain height and opens the mold, the preform in the half mold 103 automatically falls into the corresponding transition mold 106 below, and then the transition mold 106 drives the preform to return horizontally to the central axis position of the whole machine; at this time, the bottle-taking mechanism first descends to clamp the preform and then moves up to a certain height and stops to take the preform out of the transition mold 106; finally, the transfer mechanism moves horizontally to clamp the preform on the bottle-taking mechanism and then moves longitudinally to the next process.

[0004] In this patent, since the transition mold 106 cannot be opened, a bottle-taking mechanism is required to be provided to take the preform out of the transition mold 106 upwards. The addition of the bottle-taking mechanism not only makes the overall device complicated and increases the manufacturing cost, but also the operation process of first descending to take the bottle and then moving up to a certain height and stopping to wait makes the preform exposed to the air for a long time, resulting in a large heat loss. Additional heating is required before subsequent pre-blowing or formal bottle blowing, which not only consumes energy and increases costs, but also seriously affects work efficiency.

[0005] Secondly, due to the structural setting of the bottle receiving mechanism and the bottle taking mechanism, the operation of the device is complicated and has many steps, which not only makes it difficult to seamlessly connect the injection molding and embryo taking steps of the bottle embryo forming mold, but also causes a long period of work idleness, and the subsequent processes cannot be connected to carry out continuous and efficient production of multiple batches, and the existing injection molding module 100 is intermittent injection molding, which cannot achieve continuous injection molding to meet efficient production.

[0006] Thirdly, since the bottle receiving mechanism has a transverse reciprocating movement along the width direction, in order to avoid interference, the transfer mechanism can only be arranged on the transverse outward side of the bottle receiving mechanism, that is, the transfer mechanism can only transfer after clamping the bottle preform on one side of the bottle preform, and cannot be arranged on both sides of the bottle preform to relatively clamp the bottle preform and then transfer; and the position where the bottle preform of the bottle receiving mechanism and the transfer mechanism intersect is the central axis position of the entire device, and the subsequent heat preservation device, pre-blowing device, bottle blowing device, filling device, sealing device, output device, etc. are arranged in sequence along the central axis (the injection molding module 100 is located on one side of the central axis). In order to avoid interference between the transfer mechanism and the bottle receiving mechanism, the transfer mechanism has both transverse and longitudinal movements. Each time it moves, it first moves horizontally close to the central axis to take the bottle, then moves longitudinally to the next station, then exits horizontally, and finally returns longitudinally to the initial position to wait. Its movement route is a "mouth" shape repetition, so the transfer mechanism has a complex structure, a complex movement process, a high preparation cost, and low work efficiency.

[0033] The present invention has the following beneficial effects:

[0034] In the present invention, the linear transfer device is provided to replace the actions of the existing bottle receiving mechanism and bottle taking mechanism, thereby greatly simplifying the structure of the production line and reducing the manufacturing cost. The linear transfer device structure can be simply provided, and the actions and control processes are much simpler than the sum of the actions of the existing bottle receiving mechanism and bottle taking mechanism, so that the action precision is high and the control is simple. At the same time, the production efficiency is greatly improved due to the great simplification of the action process. On the second hand, in the prior art, due to the action setting of the bottle taking mechanism, the preforms are exposed to the air for a long time and the heat loss is serious. In the present invention, the linear transfer device is provided so that the preforms out of the mold can fall freely into it, thereby eliminating the setting of the existing bottle taking mechanism, making the overall structure simple and the manufacturing cost low. At the same time, The linear transfer device can also be quickly closed to clamp and keep the preforms warm, so as to prevent the preforms from being exposed to the air for a long time, so that the preforms can enter the linear transfer device for heat preservation in a very short time, so that the preforms are exposed to the air for a very short time and the heat loss is low, so it is very likely that no additional heating is required before the subsequent pre-blowing or formal bottle blowing (in the prior art, since the preforms are exposed to the air for a long time, the preforms are very easy to cool down. Depending on the material of the preforms, most of the materials need to be reheated before pre-blowing or bottle blowing. In the present application, since the preforms are exposed to the air for a very short time after being ejected from the mold, only very few types of preforms need to be reheated later), which reduces energy consumption and cost, while improving production efficiency;

[0035] On the third aspect, in the production line of the present invention, the bottle entry and exit lines of the preform molding mold, the handover station, the bottle blowing device, the filling device, the sealing device and the bottle discharging device are the same central axis, so that the production line of the present invention is a real linear production line, while in the prior art, since the injection molding module and the other devices are lateral offset (in fact, the bottle receiving mechanism and the subsequent others form a straight line), the prior art device is not a linear production line in the strict sense; on the fourth aspect, in the prior art, due to the setting of the bottle receiving mechanism and the bottle taking mechanism, the transfer mechanism can only clamp the bottle body on one side of the bottle body, and the transfer mechanism has displacement in both the lateral and longitudinal directions, and the displacement route is a "mouth" type connected in sequence, which leads to a complex structure and a complex action process of the transfer mechanism, high preparation cost and low work efficiency. In the production line of the present invention, since the linear transfer device can be opened in the lateral width direction, the bottle conveying device slides back and forth between adjacent stations along the central axis, so that the bottle conveying device structure can be simply set and the action process is also simple, thereby greatly reducing the preparation cost and improving the production efficiency.

[0036] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0056] Reference Figure 2 The preferred embodiment of the present invention provides a linear injection-blow-fill-seal integrated machine, comprising a frame, a vertical injection molding machine, a transfer station, a bottle blowing device 60, a filling device 70, a sealing device 80 and a bottle discharging device 90 arranged on the frame, and a linear transfer device 40 for transferring bottle preforms, and a bottle conveying device for conveying bottles, and the bottle preform molding mold 20, the transfer station, the bottle blowing device 60, the filling device 70, the sealing device 80 and the bottle discharging device 90 in the vertical injection molding machine have the same central axis 110 for entering and exiting the bottles; the linear transfer device 40 is arranged on the bottle preform molding mold 20, the transfer station, the bottle blowing device 60, the filling device 70, the sealing device 80 and the bottle discharging device 90 to slide back and forth along the central axis 110; The linear transfer device 40 is arranged between the bottle preform forming mold 20 and the handover station, and the linear transfer device 40 is opened and closed along the horizontal width direction of the frame to receive and keep warm a row of bottle preforms that fall freely from the bottle preform forming mold 20 when it is ejected from the mold, and slide to transfer the bottle preforms from the bottle preform forming mold 20 to the handover station; the bottle conveying device is arranged between the handover station and the sealing device 80 to simultaneously clamp multiple groups of bottle columns arranged in sequence on the central axis 110 between the handover station and the sealing device 80, so that each group of bottle columns moves to the next station along the central axis 110 respectively, and after the multiple groups of bottle columns move to the next station respectively, the bottle conveying device retreats to the previous station along the central axis 110.

[0057] In the present invention, the preform molding mold 20 is formed by removing the transition mold 106 from the existing injection molding module 100. When working, the upper mold of the preform molding mold 20 drives the prepared preform rows arranged in sequence along the longitudinal direction to move upward to be pulled out from the lower mold below. During the process of the upper mold driving the preform row to move upward, the linear transfer device 40 slides to the bottom of the upper mold along the central axis 110, and the linear transfer device 40 is slightly opened or not opened in the horizontal width direction; during the process of the upper mold driving the preform row to continue to rise, the upper mold is opened, and all the preforms in the preform row fall freely downward to the linear transfer device 40 below. After all the preforms enter the linear transfer device 40, the linear transfer device 40 clamps the preform row and keeps the preforms warm at the same time, and then The linear transfer device 40 then drives the preform array to slide along the central axis to the handover station. After sliding into place, the linear transfer device 40 opens to expose the preform array. At this time, the bottle conveying device (not shown) is started, and the bottle preform array at the handover station, the bottle bodies blown by the preforms at the blowing station, the material bottles formed after filling at the filling station, and the sealed bottles formed after sealing at the sealing station are clamped by both sides of the preform array at the same time, and then drives the bottle bodies at each clamped station to move one station along the central axis, so that the preform array moves to the blowing station, the bottle bodies move to the filling station, the material bottles move to the sealing station, and the sealed bottles move to the bottle output station. Finally, the bottle conveying device releases the clamped bottles and retreats to the previous station along the central axis, thereby realizing continuous production on the central axis 110.

[0058] In the present invention, the linear transfer device 40 is provided to replace the existing bottle receiving mechanism and bottle taking mechanism, thereby greatly simplifying the structure of the production line and reducing the manufacturing cost. The linear transfer device 40 can be simply provided, and the operation and control process are much simpler than the sum of the operations of the existing bottle receiving mechanism and bottle taking mechanism, so that the operation precision is high and the control is simple. At the same time, the production efficiency is greatly improved due to the great simplification of the operation process. On the second hand, in the prior art, due to the operation setting of the bottle taking mechanism, the preforms are exposed to the air for a long time and the heat loss is serious. In the present invention, the linear transfer device 40 is provided so that the preforms out of the mold can fall freely into it, thereby eliminating the setting of the existing bottle taking mechanism, making the overall structure simple and the manufacturing cost low. The linear transfer device 40 can also be quickly closed to clamp and keep the preforms warm, so as to prevent the preforms from being exposed to the air for a long time, so that the preforms can enter the linear transfer device 40 for heat preservation in a very short time, so that the preforms are exposed to the air for a very short time and the heat loss is low, so it is very likely that no additional heating is required before the subsequent pre-blowing or formal bottle blowing (in the prior art, since the preforms are exposed to the air for a long time, the preforms are very easy to cool down. Depending on the material of the preforms, most of the materials need to be reheated before pre-blowing or bottle blowing. In the present application, since the preforms are exposed to the air for a very short time after being ejected from the mold, only very few types of preforms need to be reheated later), which reduces energy consumption and cost, and improves production efficiency at the same time;

[0059] Thirdly, in the production line of the present invention, the bottle preform forming mold 20, the handover station, the bottle blowing device 60, the filling device 70, the sealing device 80 and the bottle discharging device 90 have the same central axis 110 for the bottle in and out, so that the production line of the present invention is a real linear production line, while in the prior art, due to the lateral deviation between the injection molding module 100 and the other devices (in fact, the bottle receiving mechanism and the subsequent others form a straight line), the prior art device is not a linear production line in the strict sense; Fourthly, in the prior art, due to the arrangement of the bottle receiving mechanism and the bottle taking mechanism, It also results in the transfer mechanism being able to clamp the bottle body only on one side of the bottle body, and the transfer mechanism having displacements in both lateral and longitudinal directions, and the displacement route being a "mouth" type connected in sequence, which results in a complex structure and a complex action process of the transfer mechanism, high preparation cost, and low work efficiency. In the production line of the present invention, since the linear transfer device 40 can be opened along the lateral width direction, the bottle conveying device can slide back and forth between adjacent workstations along the central axis 110, so that the bottle conveying device structure can be simply set and the action process is also simple, thereby greatly reducing the preparation cost and improving production efficiency at the same time.

[0060] Alternatively, if Figure 4 and Figure 6 As shown, the linear transfer device 40 includes a heat preservation demoulding device 42 that is reciprocatingly slidable along the central axis 110. The heat preservation demoulding device 42 is transversely opened and closed with the central axis 110 as the opening and closing line, so as to clamp and heat the preform row. During operation, the upper mold of the preform molding mold 20 drives the preform row to move upward, and the heat-insulating mold device 42 slides to the bottom of the upper mold along the central axis 110. At this time, the heat-insulating mold device 42 is slightly opened or not stuck in the transverse width direction. The upper mold drives the preform row to continue to rise, and the upper mold opens. All the preforms in the preform row fall freely downward into the heat-insulating mold device 42 below. After all the preforms enter the heat-insulating mold device 42, the heat-insulating mold device 42 clamps the preform row and keeps the preforms warm at the same time. Finally, the heat-insulating mold device 42 drives the preform row to slide along the central axis 110 to the handover station. After the heat-insulating mold device 42 moves into place at the handover station, it opens to expose the preform row. The bottle conveying device located at the handover station is actuated to clamp the preform row, so that the bottle conveying device clamps the preform row and moves longitudinally to the next station.

[0061] The heat-insulating demoulding device 42 includes a clamping frame group 422 extending in the longitudinal direction, and the clamping frame group 422 includes a first clamping frame 4221 and a second clamping frame 4222 respectively arranged on both sides of the bottle preform row, and the first clamping frame 4221 and the second clamping frame 4222 are close together to form a plurality of accommodating cavities arranged in sequence along the arrangement direction of the bottle preform row, so as to accommodate the fallen bottle preform rows one by one and keep them warm, or relatively move away to expose the bottle preform rows, so as to facilitate the bottle conveying device to clamp the bottle preform rows from both sides of the bottle preform row and convey them in a straight line along the central axis 110. In this optional solution, since the first clamping frame 4221 and the second clamping frame 4222 are respectively arranged on both sides of the bottle preform row, and the first clamping frame 4221 and the second clamping frame 4222 are brought together to form a plurality of accommodating cavities arranged in sequence along the arrangement direction of the bottle preform row, the bottle preform row that falls freely after being ejected from the mold can still be arranged in the heat-insulating ejection device 42 after falling along the original arrangement line direction, and the closed clamping frame group 422 is also used to keep the bottle preforms located in the accommodating cavities warm; after the clamping frame group 422 is opened, the bottle preform row can be exposed, thereby facilitating the bottle conveying device to clamp the bottle preform row from both sides of the bottle preform row and then convey it to the handover station in a straight line along the central axis 110.

[0062] In this option, if Figure 5 As shown, the first clamping frame 4221 and the second clamping frame 4222 have a plurality of concave receiving grooves 4220 arranged in sequence and spaced in the length direction on the opposite surfaces thereof. When the first clamping frame 4221 and the second clamping frame 4222 are closed, the two opposite receiving grooves 4220 form a receiving cavity. In this optional solution, each preform corresponds to a receiving cavity, so that each preform is clamped and kept warm by the first clamping frame 4221 and the second clamping frame 4222, thereby improving the stability of the preform clamping and the heat preservation effect. In addition, the structure of the clamping frame group 422 is simple and the preparation cost is low.
