The blank making machine and the bottle blowing machine are important components of a bottle making system, and are respectively used for making a raw material into a bottle blank and blowing the bottle blank into a bottle so as to finish the blank making and bottle blowing processes.

Fig. 1 exemplarily shows a structure of a bottle making system in the related art.

Referring to fig. 1, a bottle-making system 10 includes a blank-making machine 1, a bottle-blowing apparatus 2 and a blank-feeding mechanism 3, which are respectively used for making a bottle blank, blowing the bottle blank into a bottle, and conveying the bottle blank made by the blank-making machine 1 to the bottle-blowing apparatus 2.

Wherein, the blank making machine 1 is arranged in a blank making workshop 4, and the discharge hole is positioned at a higher position above the ground.

The bottle blowing equipment 2 is arranged in a bottle blowing workshop 5 and comprises a bottle blowing machine 21 and a blank arranging machine 22. The bottle blowing machine 21 is used for blowing the bottle preform into a bottle. The blank arranging machine 22 is arranged at the upstream of the bottle blowing machine 21 and is used for arranging the blanks before the blanks reach the bottle blowing machine 21, so that the blanks blown by the bottle blowing machine 21 are the blanks arranged by the blank arranging machine 22. The bottle blowing machine 21 and the blank arranging machine 22 are both positioned at a certain height above the ground, and the heights of the bottle blowing machine and the blank arranging machine are usually different from the height of a discharge port of the blank making machine 1. Generally, the bottle blowing machine 21 and the blank arranging machine 22 are lower than the discharge port of the blank making machine 1.

It can be seen that the blank making machine 1 and the bottle blowing machine 21 are in different workshops and at different heights.

In order to realize the transfer of the bottle preform from the preform making machine 1 to the bottle blowing machine 21, as shown in fig. 1, in the related art, the preform feeding mechanism 3 includes a transfer mechanism 31, a discharge hopper 36, a transfer container 37, a collection container 39 and a conveying mechanism 38.

Wherein, the conveying mechanism 31 and the blanking hopper 36 are both arranged in the blank-making workshop 4; the collecting container 39 and the conveying mechanism 38 are both arranged in the bottle blowing workshop 5; the transfer container 37 is moved between the preform workshop 4 and the bottle blowing workshop 5.

Specifically, the conveying mechanism 31 includes a first conveying section 311 connected to the discharge port of the blank making machine 1 and extending in the longitudinal direction for conveying the bottle blanks made by the blank making machine 1 downward to the discharge hopper 36. The longitudinal direction is a direction parallel to the vertical direction or inclined with respect to the vertical direction.

The lower hopper 36 is connected below the first conveying section 311 to receive the preforms conveyed by the conveying mechanism 31.

The transfer container 37 is disposed on the ground for receiving the preforms dropped from the lower hopper 36 and transferring the preforms to the collection container 39. The transfer container 37 is movable between the preform machine 1 and the collection container 39 to receive the preforms and transfer them to the collection container 39. The horizontal arrows in fig. 1 indicate the reciprocating movement of the transfer container 37 between the blank maker 1 and the collecting container 39. Along the horizontal arrow, the transfer container 37 can be moved from below the discharge hopper 36 to the position of the collecting container 39 for discharge. Meanwhile, after the unloading is finished, the transfer container 37 can move reversely, returns to the position below the discharging hopper 36 from the position of the collecting container 39, and continues to receive bottle blanks. Specifically, the movement of the transfer container 37 is performed by manual pushing.

The collecting container 39 is disposed on the ground of the bottle blowing workshop 5 for collecting bottle blanks. The collection container 39 is provided with a dump hopper 391. The dump box 391 is rotatably disposed on the collecting container 39 for driving the transferring container 37 to overturn so that the bottle preforms in the transferring container 37 fall into the collecting container 39.

The conveying mechanism 38 is connected with the collecting container 39 and the blank arranging machine 22 to convey the bottle blanks in the collecting container 39 to the blank arranging machine 22, so that the bottle blanks are conveyed to the bottle blowing machine 21 after being arranged by the blank arranging machine 22. Since the collecting container 39 is provided on the ground and the blank trimming machine 22 is located above the ground, the transfer mechanism 38 is usually arranged obliquely upward.

During operation, the bottle blanks made by the blank making machine 1 are conveyed by the conveying mechanism 31 and then fall into the blanking hopper 36, then the blanking hopper 36 is opened, the bottle blanks fall into the transfer container 37 from the blanking hopper 36, after the transfer container 37 is filled, the transfer container 37 is manually pushed into the bottle blowing workshop 5 from the blank making workshop 4 and pushed onto the skip 391, then the skip 391 drives the transfer container 37 to turn over, so that the opening of the transfer container 37 is positioned right above the inlet of the collecting container 39 and faces the collecting container 39, then the bottle blanks in the transfer container 37 fall into the collecting container 39 and are collected by the collecting container 39, then the bottle blanks collected by the collecting container 39 are sent to the blank arranging machine 22 by the conveying mechanism 38, after the blank arranging machine 22 is arranged, the bottle blanks are sent to the bottle blowing machine 21, and the bottle blowing machine 21 blows the bottle blanks into bottles.

In the above process, before the bottle blank falls into the collection container 39, three drops are required, namely, the drop from the conveying mechanism 31 to the lower hopper 36, the drop from the lower hopper 36 to the transfer container 37, and the drop from the transfer container 37 to the collection container 39, the number of drops is large, the collision risk is large, and the drop height is high when the lower hopper 36 falls into the transfer container 37 and the transfer container 37 falls into the collection container 39, for example, the drop height can reach 40-50 cm when the lower hopper 36 falls into the transfer container 37, which causes great impact to the bottle mouth or the blank body to collide and damage in the falling process of the bottle blank, and affects the quality of the finished product. This phenomenon is more serious when the bottle preform is heavier and the diameter of the bottle mouth is larger, and for example, the bottle preform with a large gram weight (usually the weight is more than 45 g) and a large bottle mouth (usually the diameter of the bottle mouth is more than 3.8 cm) is particularly easy to knock and damage.

Moreover, because the transfer container 37 needs to be manually pushed to convey the bottle blanks to the collection container 39, and manual pushing is time-consuming and labor-consuming, there is a problem of low efficiency, which affects the production efficiency of the bottle-making system 10.

In view of the above, the present application improves upon the construction of the bottle-making system 10.

Fig. 2-5 schematically illustrate the construction of the present bottling system 10.

Referring to fig. 2, in the present application, a bottle making system 10 includes a blank making machine 1, a bottle blowing machine 21 and a blank feeding mechanism 3. Wherein the blank making machine 1 is used for making bottle blanks. The bottle blowing machine 21 is used for blowing bottle blanks into bottles. The blank feeding mechanism 3 comprises a conveying mechanism 31 and a buffer hopper 32, the conveying mechanism 31 is connected with the blank making machine 1 and the buffer hopper 32 to convey the bottle blanks made by the blank making machine 1 into the buffer hopper 32, and the buffer hopper 32 is arranged above the blank arranging machine 22 to release the bottle blanks onto the blank arranging machine 22.

Based on the above arrangement, when the bottle-making system 10 works, the bottle blanks made by the blank-making machine 1 may fall into the buffer hopper 32 through the conveying mechanism 31, then directly fall onto the blank-arranging machine 22 from the buffer hopper 32, and after being arranged by the blank-arranging machine 22, reach the bottle-blowing machine 21, and are blown into bottles by the bottle-blowing machine 21.

In the working process, the bottle blanks can reach the blank arranging machine 22 only through two-stage conveying of the conveying mechanism 31 and the buffer hopper 32, the bottle blanks can reach the blank arranging machine 22 without passing through the discharging hopper 36, the transferring container 37, the collecting container 39 and the conveying mechanism 38, the conveying level is reduced, the falling frequency of the bottle blanks is reduced, and the falling height is reduced, so that the bottle blank collision risk can be effectively reduced, and the collision damage of the bottle blanks is reduced.

Therefore, the conveying mechanism 31 and the buffer hopper 32 can directly realize material communication between the blank making machine 1 and the blank arranging machine 22, so that the bottle blanks can reach the blank arranging machine 22 without passing through the blanking hopper 36, the transferring container 37, the collecting container 39 and the conveying mechanism 38, the bottle blank conveying level number and falling frequency can be effectively reduced, the falling height of the bottle blanks can be reduced, collision damage of the bottle blanks can be effectively reduced, and the improvement of the quality of finished products is facilitated.

In addition, because based on the buffer hopper 32 that sets up, can realize the full-automatic transportation process of bottle base by blank making machine 1 to collection container 39 for the transportation of transporting container 37 no longer is the necessary link, that is to say, need not artifical promotion and transports container 37, can deliver to reason blank machine 22 with the bottle base, consequently, still be favorable to practicing thrift manpower and time, improve the transport efficiency of bottle base, and then promote bottle-making efficiency.

It can be seen that, by improving the structure of the blank feeding mechanism 3 and directly arranging the buffer hopper 32 above the blank arranging machine 22, the bottle blank collision damage can be reduced, the quality of finished products can be improved, the production rhythm can be accelerated, and the production efficiency can be improved.

Referring to fig. 2, in some embodiments, the blank feed mechanism 3 includes a detector 35, and the detector 35 detects the level of material in the buffer hopper 32.

Based on the detector 35, the material level condition of the buffer hopper 32 can be conveniently and accurately known, and the control system can conveniently work.

For example, it is possible to determine whether the level in the buffer hopper 32 has reached the set level based on the detection result of the detector 35, and further determine whether it is necessary to control the buffer hopper 32 to release the preforms. When the detector 35 detects that the material level in the buffer hopper 32 has reached the set material level, which indicates that the number of the bottle blanks in the buffer hopper 32 is sufficient, it is determined that the material receiving of the buffer hopper 32 is completed, and at this time, the buffer hopper 32 is controlled to be opened, so that the bottle blanks fall onto the blank arranging machine 22.

For another example, it may be determined whether the material level in the buffer hopper 32 exceeds the upper limit and/or is lower than the lower limit based on the detection result of the detector 35, so as to achieve a safer and smoother blank feeding process. If the level of the buffer hopper 32 is abnormal, exceeds the upper limit, or falls below the lower limit, it may indicate that the bottle-making system 10 is operating abnormally. For example, if the material level of the buffer hopper 32 exceeds the upper limit, it indicates that there may be a problem that the buffer hopper 32 does not stop receiving material in time, or the bottle blowing apparatus 2 fails, and the bottle blank cannot be consumed in time. For another example, if the material level of the buffer hopper 32 is lower than the lower limit, it indicates that there may be a problem that the buffer hopper 32 does not receive the material in time, or the conveying mechanism 31 fails, and the bottle blank cannot be conveyed in time. It can be seen that the abnormal material level in the buffer hopper 32 is a reflection of the equipment failure, and may affect the stable blank supply of the bottle blowing equipment 2, resulting in abnormal production. Therefore, it is necessary to take measures for detecting whether or not the material level in the buffer hopper 32 is abnormal in order to find a failure in time.

To achieve the detection of the abnormal material level in the buffer hopper 32, referring to fig. 2, in some embodiments, the detector 35 includes a first detecting member 352 and a second detecting member 353, and the first detecting member 352 and the second detecting member 353 are disposed in the buffer hopper 32 and are sequentially arranged along the direction from the top to the bottom to detect whether the material level in the buffer hopper 32 exceeds the upper limit and is lower than the lower limit, respectively. In this way, it can be determined in time whether the level in the buffer hopper 32 exceeds the upper limit and is below the lower limit by the first and second detecting members 352 and 353. Illustratively, the first and/or second detection members 352, 353 include a proximity switch 351.

Additionally, to more timely detect a level anomaly, referring to FIG. 3, in some embodiments, the bottle making system 10 includes an alarm 33, the alarm 33 being coupled to a detector 35 and alarming when the detector 35 detects that the level in the surge hopper 32 exceeds an upper limit and/or falls below a lower limit. In particular, when the detector 35 comprises a first 352 and a second 353 detection member, the alarm 33 may be in signal connection with both the first 352 and the second 353 detection member so as to alarm both when the level of material in the buffer hopper 32 exceeds an upper limit and when it falls below a lower limit.

Based on the alarming function of the alarm 33, the abnormal situation of the material level can be found more timely, so that the equipment fault can be processed more timely, and the stable blank supply of the bottle blowing equipment 2 is realized.

In the foregoing embodiments, the structure of the conveying mechanism 31 may be varied.

For example, in some embodiments, the conveying mechanism 31 includes a belt conveying mechanism or a chain conveying mechanism to convey the preforms using a conveyor belt or a conveyor chain.

For another example, with reference to fig. 2, in some embodiments, the conveying mechanism 31 comprises a first conveying section 311 and a second conveying section 312, the first conveying section 311 extending in the longitudinal direction and being connected to the blank maker 1, the second conveying section 312 extending in the transverse direction and connecting the first conveying section 311 and the buffer hopper 32.

Because conveying mechanism 31 not only includes along longitudinally extending's first conveying section 311, still includes along transversely extending's second conveying section 312 simultaneously, and transversely extending's second conveying section 312 can compensate the transverse distance between blank making machine 1 discharge gate and the reason base machine 22, consequently, more conveniently make buffer hopper 32 be located reason base machine 22 top, make buffer hopper 32 can directly release the bottle base to reason base machine 22 on, and need not just like hopper 36 down, still need pass through the transfer container 37, the transfer of collecting container 39 and transport mechanism 38, and then can effectively reduce and collide with, and raise the efficiency.

As mentioned above, the buffer hopper 32 is provided, so that the transfer container 37 is no longer an essential link for transferring the bottle blanks, and therefore, the transfer container 37 can be removed directly, and is not provided, on the basis of which, the discharging hopper 36, the collecting container 39, the skip 391 and the conveying mechanism 38 can be removed directly, and are not used, so that the blank conveying mechanism 3 no longer includes the transfer container 37, the discharging hopper 36, the collecting container 39, the skip 391 and the conveying mechanism 38, and the conveying of the bottle blanks is completed only under the cooperation of the conveying mechanism 31 and the buffer hopper 32.

However, in order to improve the operational flexibility of the bottle-making system 10, referring to fig. 2, in some embodiments, while the buffer hopper 32 is provided, the transfer container 37, the collecting container 39 and the conveying mechanism 38 are still retained, that is, the blank-conveying mechanism 3 includes not only the conveying mechanism 31 and the buffer hopper 32, but also the transfer container 37, the collecting container 39 and the conveying mechanism 38, which is advantageous in that the blank-conveying mechanism 3 can not only realize the conveying of the bottle blanks based on the buffer hopper 32, but also realize the conveying of the bottle blanks by adopting the conventional transfer container 37 transfer mode, thereby being more flexible to meet the requirements of different situations.

For example, when both the preform machine 1 and the bottle blowing machine 21 are normally produced, the preform can be transported only by the buffer hopper 32 without using the transfer container 37, so that the collision of the preforms can be effectively reduced in most of the time.

For another example, when the blank making machine 1 is in normal production and the bottle blowing machine 21 is stopped in production due to maintenance and the like, the buffer hopper 32 may be stopped, the conventional transfer container 37 may be started, and the transfer container 37 is used to receive the blank made by the blank making machine 1, so as to temporarily store the blank by the transfer container 37 for use by the subsequent bottle blowing machine 21.

For example, when the preform maker 1 stops operating due to maintenance or the like, but the bottle blowing machine 21 is still operating normally, the transfer container 37 in which the preforms are stored temporarily may be pushed to the collection container 39, so that the preforms required for the bottle blowing machine 21 may be supplied by the cooperation of the transfer container 37, the collection container 39, and the transfer mechanism 38.

It can be seen that, the blank feeding mechanism 3 includes the buffer hopper 32 and the transfer container 37 at the same time, so that the working flexibility of the bottle making system 10 can be effectively improved, and the actual requirements of different working conditions can be better met.

When the blank feeding mechanism 3 includes the transfer container 37, the blank feeding mechanism 3 may include a skip 391 at the same time, so as to implement the transfer of the blank in the transfer container 37 to the collection container 39 by turning over the transfer container 37 with the conventional skip 391, so that, when necessary, for example, the blank making machine 1 stops working due to maintenance, etc., but the bottle blowing machine 21 still works normally, the transfer container 37 originally storing the blank temporarily can be pushed to the collection container 39 and onto the skip 391, and the transfer container 37 is turned over by the skip 391, so as to implement the supply of the blank required by the bottle blowing machine 21.

The embodiments shown in fig. 2-3 will be further described below.

As shown in fig. 2-3, in this embodiment, the bottle making system 10 includes a blank making machine 1, a bottle blowing apparatus 2, a blank feeding mechanism 3 and an alarm 33. The bottle blowing equipment 2 comprises a bottle blowing machine 21 and a blank arranging machine 22. The blank feeding mechanism 3 includes a conveying mechanism 31, a buffer hopper 32, a collecting container 39, a conveying mechanism 38, a discharging hopper 36, and a transfer container 37. The conveying mechanism 31 includes a first conveying section 311 and a second conveying section 312.

The blank making machine 1 and the bottle blowing equipment 2 are both located above the ground, the height of the bottle blowing equipment 2 is lower than that of a discharge port of the blank making machine 1, and meanwhile, the blank making machine and the bottle blowing equipment also have offset in the horizontal direction.

The first conveying section 311 is connected below the discharge port of the blank making machine 1 and is communicated with the discharge port of the blank making machine 1. The second conveying section 312 is connected to the first conveying section 311 and extends horizontally, so that the conveying mechanism 31 extends from the blank making machine 1 to the bottle blowing apparatus 2 as a whole.

A lower hopper 36 is connected below the first conveying section 311. The buffer hopper 32 is connected below the second conveying section 312 and above the blank arranging machine 22.

The collection container 39 and the transfer container 37 are both disposed on the ground. Wherein the collecting container 39 is fixed to the ground and is in material communication with the blank unscrambler 22 via a conveying mechanism 38 extending obliquely upwards. The transfer container 37 is then moved between a position below the lower hopper 36 and a position where the collection container 39 is located. The horizontal arrows in fig. 2 indicate the horizontal movement of the transfer container 37.

The dump hopper 391 is provided on the collecting container 39 so that the transfer container 37 is turned over after the transfer container 37 is moved to the dump hopper 391, thereby transferring the preforms in the transfer container 37 to the collecting container 39.

Two proximity switches 351 are provided on the buffer hopper 32. The two proximity switches 351 are arranged at intervals up and down, and serve as a first detecting member 352 and a second detecting member 353, respectively, to detect whether the level of the material in the buffer hopper 32 has exceeded the upper limit and fallen below the lower limit. Two proximity switches 351 all are connected with alarm 33 signal for alarm 33 can be in the position of the material level in buffer hopper 32 exceed the upper limit and be less than the lower limit, report to the police to realize height material level alarming function, and then supply the base for bottle blowing equipment 2 steadily.

In this embodiment, the blank feeding mechanism 3 performs blank feeding based on the buffer hopper 32 in most cases, and the transfer container 37 is activated to perform blank feeding only when one of the blank making machine 1 and the bottle blowing machine 21 is operated and the other is stopped.

Specifically, under normal conditions, both the blank making machine 1 and the bottle blowing machine 21 are normally operated, and in this case, the bottle blanks made by the blank making machine 1 sequentially pass through the first conveying section 311 and the second conveying section 312, fall into the buffer hopper 32, then fall into the blank arranging machine 22 from the buffer hopper 32, are arranged by the blank arranging machine 22, then reach the bottle blowing machine 21, and are blown into bottles by the bottle blowing machine 21.

And when the bottle blowing machine 21 is stopped and the blank making machine 1 still works normally, the second conveying section 312 and the buffer hopper 32 are stopped, and simultaneously, the first conveying section 311, the blanking hopper 36 and the transfer container 37 work, so that the bottle blanks made by the blank making machine 1 can fall into the blanking hopper 36 through the first conveying section 311, and then fall into the transfer container 37 through the blanking hopper 36, thereby realizing the temporary storage of the bottle blanks by the transfer container 37.

In addition, when the preform making machine 1 stops and the bottle blowing machine 21 operates, the second conveying section 312 and the buffer hopper 32 also stop operating, and at the same time, the transfer container 37 filled with the preforms is manually pushed to the collecting container 39 and onto the skip 391, the transfer container 37 is turned over by the skip 391, so that the preforms in the transfer container 37 fall into the collecting container 39, and are further conveyed to the bottle blowing machine 21 by the conveying mechanism 38 and the preform sorting machine 22, and are blown into bottles by the bottle blowing machine 21.

Because under most circumstances, all carry out the bottle base conveying based on buffer hopper 32, and the bottle base transport mode based on buffer hopper 32, carry the rank few, the bottle base falls the number of times few, and the whereabouts height is low, consequently, can effectively reduce the bottle base and collide with. In the corresponding process, the bottle blank conveying is fully automatic, and the transfer container 37 does not need to be pushed manually, so that the efficiency is higher.

Moreover, because the transfer container 37 and the tipping bucket 391 are reserved at the same time, the bottle-making system 10 can still work when only one of the blank-making machine 1 and the bottle blowing machine 21 can work, and the machine does not need to be stopped, thereby being beneficial to improving the production efficiency.

Therefore, the bottle making system 10 of the embodiment has the advantages of high efficiency, less bottle blank collision and high finished product quality, and is particularly suitable for bottle production with large gram weight and/or large bottle mouth.

It is understood that material communication means that material transfer, in particular, preform transfer, is possible. In the present application, the material communication is performed between the conveying mechanism 31 and the blank making machine 1, between the conveying mechanism 31 and the buffer hopper 32, between the buffer hopper 32 and the blank arranging machine 22, between the collecting container 39 and the conveying mechanism 38, between the conveying mechanism 38 and the bottle blowing device 2, between the conveying mechanism 31 and the discharging hopper 36, and between the discharging hopper 36 and the transferring container 37, and further, the material communication is performed between the buffer hopper 32 and the blank making machine 1 through the conveying mechanism 31, and meanwhile, the material communication is performed between the collecting container 39 and the bottle blowing machine 21 and the blank arranging machine 22 through the conveying mechanism 38.

In addition, in order to enable the buffer hopper 32 to release the preforms when needed, referring to fig. 4 to 5, the buffer hopper 32 may include a hopper body 3a and an opening and closing mechanism 3b. The opening and closing mechanism 3b is arranged on the bucket body 3a and controls the opening and closing of the bottom opening of the bucket body 3a so as to control whether to release the bottle blank.

The structure of the opening and closing mechanism 3b may be various.

For example, referring to fig. 4 and 5, in some embodiments, the opening and closing mechanism 3b includes a base plate 3c and an opening and closing driving mechanism 3d. The bottom plate 3c is slidably or rotatably attached to the bottom end of the bucket body 3 a. The opening and closing driving mechanism 3b is in driving connection with the bottom plate 3c, and controls the opening and closing of the bottom opening of the bucket body 3a by driving the bottom plate 3c to slide or rotate between an open position and a closed position. Specifically, in some embodiments, the opening and closing drive mechanism 3b includes a drive cylinder 34.

Fig. 4 and 5 show the case where the bottom plate 3c is slidably disposed and rotatably disposed, respectively. In fig. 4 and 5, the broken line indicates a state where the bottom plate 3c is in the closed position, and the solid line indicates a state where the bottom plate 3c is in the open position.

It is to be understood that the configuration of the surge hopper 32 is not limited to that shown in fig. 4 and 5.

For example, in other embodiments, the opening and closing mechanism 3b includes a bottom plate 3c and a locking mechanism (not shown). The bottom plate 3c is rotatably connected to the bottom end of the bucket body 3 a. The lock mechanism connects the base plate 3c and the bucket body 3a, and is switchable between a locked state and an unlocked state. When the bucket is in a locked state, the locking mechanism locks the bottom plate 3c on the bucket body 3a, and the bottom opening of the bucket body 3a is closed. When the bottle is in an unlocking state, the locking mechanism releases the locking of the bottom plate 3c, and the bottom plate 3c rotates under the self gravity and the bottle blank pressure, so that the bottom opening of the bucket body 3a is opened.

It will be appreciated that in addition to the above-described configuration of the buffer hopper 32 for controlling the release of preforms, the discharge hopper 36 may also be configured to control the release of preforms.

The above description is only exemplary of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like that are made within the spirit and principle of the present application should be included in the protection scope of the present application.
