Fig. 1 to 12 exemplarily show the structure and operation of the cassette supply system and the cassette handling apparatus thereof in the present application.

Referring to fig. 1-12, in the present application, a cassette supply system 10 includes a feed mechanism 300 and a cassette handling apparatus 100. The cassette handling apparatus 100 is configured to handle the cassette stack 4 on the loading device 200 to the feeding mechanism 300. The feeding mechanism 300 is configured to feed the box segments 42 of the box segment stack 4 to a packing machine (not shown, for example, a GDX6 packing machine) for the packing machine to take the box segments 42 and pack cigarettes.

Wherein, as shown in fig. 2, the cassette stack 4 comprises a plurality of cassettes 42. The plurality of cassette sheets 42 are stacked to form a cassette stack 43. Moreover, to prevent the stack 43 from unraveling, in some embodiments, the stack 4 further includes a wrapper 41 (e.g., kraft paper). The wrapper 41 is wrapped around the outside of the stack 43 to encapsulate the stack 43. Specifically, as shown in fig. 2, in some embodiments, the wrapper 41 wraps the top, bottom, and both sides of the stack 43.

In the case where the pack 4 comprises a pack 43 and a wrapper 41, for convenience in taking the pack 42 during the wrapping of cigarettes, the pack 4 is generally removed from the wrapper 41 before being transported to the wrapping machine by the feeding mechanism 300, so that the feeding mechanism 300 transports to the wrapping machine the pack 4 without the wrapper 41, i.e. with only the pack 43 and without the wrapper 41.

In some related art, the handling of the stack 4 from the loading device 200 to the feeding mechanism 300 is performed manually. Specifically, by discharging the material, the cassette stack 4 is placed on the loading device 200. Then, the operator removes the stack 4 from the loading device 200, tears the wrapping paper 41 of the stack 4 wrapped around the outside of the stack 43, and finally, the operator conveys the stack 43 separated from the wrapping paper 41 to the feeding mechanism 300, and the feeding mechanism 300 feeds the stack.

The manual carrying scheme is low in efficiency, the labor intensity of operators is high, and in the carrying process, the problem that the box piece stacks fall off and the box piece stacks 43 are scattered easily occurs, so that the efficiency is further reduced, and the labor intensity is increased. Especially, to the packagine machine that production speed is faster, this kind of manual handling's mode is difficult to satisfy packagine machine's box demand, influences the whole production efficiency of cigarette.

In view of the above, the inventor has proposed a solution, by providing the cassette handling apparatus 100, instead of manually handling the cassette stack 4, to implement automatic handling of the cassette stack 4 from the loading device 200 to the feeding mechanism 300, thereby improving efficiency and reducing labor intensity. However, in the corresponding scheme, the cassette handling apparatus 100 can only handle one cassette stack 4 at a time, which can improve efficiency to some extent and reduce labor intensity compared with the manual handling method, but still has a problem of low efficiency.

Accordingly, in order to further improve the efficiency, the present application further improves the cassette supply system 10 and the cassette handling apparatus 100.

First, the structure of the cassette handling apparatus 100 in the present application will be described.

Referring to fig. 1 to 12, in the present application, a cassette sheet handling apparatus 100 includes a supporting device 3, a robot arm 1, and a handling mechanism 2. The robot arm 1 is movably disposed on the support device 3. The carrying mechanism 2 is connected to the mechanical arm 1, and carries the cassette stack 4 placed on the loading device 200 onto the feeding mechanism 300 under the driving of the mechanical arm 1. Wherein the handling mechanism 2 comprises at least two handling devices 22, which at least two handling devices 22 are arranged side by side along the first direction and are configured to handle one cassette stack 4 each.

In the solution previously proposed by the inventor, the handling mechanism 2 comprises only two handling devices 22, and these two handling devices 22 need to be together in order to handle one stack 4 of cassettes, which results in that the handling mechanism 2 can only handle a single stack 4 of cassettes at a time, the efficiency being to be improved. Unlike this, in the present application, the handling mechanism 2 includes at least two handling devices 22, and these at least two handling devices 22 can carry a piece stack 4 respectively, this makes handling mechanism 2 can carry at least two piece stacks 4 at a time, therefore, can effectively improve the supply efficiency of piece stack, satisfy the box demand of packagine machine that production speed is faster better, and then be favorable to promoting the whole production efficiency of cigarette.

In this application, the handling device 22 may be used to combine with the stack 4 to handle the stack 4 by clamping, supporting, grabbing or sucking.

For example, referring to fig. 1-12, in some embodiments, the handling device 22 includes a suction cup 23, the suction cup 23 being configured to suction the cassette stack 4. In this way, the carrying device 22 can carry the stack 4 by combining with the stack 4 by sucking the stack 4 by the suction cup 23.

The sucking disc 23 is utilized to suck the box sheet stack 4, so that the box sheet stack 4 is convenient and sanitary and is not easy to damage. Moreover, set up sucking disc 23 and absorb box piece and fold 4, not only can more steadily reliably carry box piece and fold 4, but also conveniently realize the separation of sucking disc 23 and box piece and fold 4 through changing sucking force size of sucking disc 23, and then conveniently handling device 22 places box piece and fold 4 in target position such as conveying mechanism 300, satisfies the handling needs. In particular, in the case where the stack 4 further includes the wrapping paper 41, the separation of the wrapping paper 41 and the stack 43 of the stack 4 may be further achieved by controlling the suction force of the suction cup 23, so that the stack 43 of the stack 4 without the wrapping paper 41 falls onto the feeding mechanism 300, and is further convenient for the packaging machine to take. For example, referring to fig. 4-5 and 10, in some embodiments, the suction cup 23 is configured such that the suction force is variable between a first value and a second value, wherein the first value is greater than the second value, and when the suction force of the suction cup 23 is the first value, the suction cup 23 pulls the entire cassette stack 4 to carry the cassette stack 4 entirely off the loading device 200 and to the transport mechanism 300; when the suction force of the suction cup 23 is the second value, the suction cup 23 sucks only the wrapping paper 41 of the stack 4 wrapped around the stacked sheets 42 and releases the stacked sheets 42 to separate the stacked sheets 42 from the wrapping paper 41 and drop onto the feeding mechanism 300. In this way, the sucking disc 23 can suck the packing paper 41 and the box sheet stack 43 wrapped by the packing paper 41 together, so that the box sheet stack 4 is integrally separated from the material loading device 200 and conveyed to the position of the material conveying mechanism 300 by the sucking disc 23, and after reaching the position of the material conveying mechanism 300, the sucking disc 23 can release the suction of the box sheet stack 43 under the condition of sucking the packing paper 41, thereby smoothly separating the packing paper 41 from the box sheet stack 43, and the box sheet stack 43 can be singly dropped onto the material conveying mechanism 300 and conveyed to the packaging machine by the material conveying mechanism 300, so that the packaging machine can conveniently take single box sheets 42.

As another example, referring to fig. 1-12, in some embodiments, the handling device 22 includes a holding jaw 24, the holding jaw 24 being configured to hold the cassette stack 4 in the operative position. In this way, the carrying device 22 can carry the stack 4 by combining with the stack 4 in a bearing manner based on the bearing of the supporting claw 24 to the stack 4.

Because the supporting claw 24 can support the box piece stack 4, the box piece stack 4 is stable and is not easy to fall down and fall off in the carrying process. Moreover, the tray claw 24 is utilized to support the cassette stack 4, and the combination and separation of the tray claw 24 and the cassette stack 4 are also conveniently realized, so that the handling device 22 can conveniently remove the cassette stack 4 from the material loading device 200 and convey the cassette stack 4 to the material conveying mechanism 300 from the material loading device 200, and the handling device 22 can conveniently release the cassette stack 4 to place the cassette stack of the cassette stack 4 on the material conveying mechanism 300 and other target positions. For example, referring to fig. 4-12, in some embodiments, the gripper 24 is movable relative to the robotic arm 1 between an operative position and an evasive position in which the gripper 24 is spaced away from the cassette stack 4. Therefore, the combination and the separation of the supporting claw 24 and the box sheet stack 4 can be controlled only by moving the supporting claw 24 between the working position and the avoiding position, and the combination is simple and convenient. Wherein movement of the pawl 24 between the operating position and the retracted position may be rotational and/or translational.

For another example, in some embodiments, the handling device 22 includes both suction cups 23 and holding claws 24, and the suction cups 23 and holding claws 24 of the same handling device 22 are spaced apart along a second direction perpendicular to the first direction to act on different portions of the same cassette stack 4. In this way, the carrying device 22 not only can utilize the suction disc 23 to suck the box piece stack 4, but also can utilize the supporting claw 24 to support the box piece stack 4, so that the box piece stack 4 can be subjected to negative pressure suction and mechanical supporting in the carrying process, which is beneficial to improving the stability of the carrying process and more reliably preventing the box piece stack 4 from toppling over, falling off and scattering. Moreover, as the sucking disc 23 and the supporting claw 24 of the same carrying device 22 act on different parts of the same cassette stack 4, the same carrying device 22 can respectively apply attractive force and supporting force to different parts of the same cassette stack 4, thereby being more beneficial to improving the stability of the carrying process.

In the case where the handling device 22 includes both the suction cup 23 and the holding claw 24, the sequence of actions of the suction cup 23 and the holding claw 24 can be designed to achieve a smoother and more reliable handling process. For example, referring to fig. 4-12, in some embodiments, the holding jaw 24 is configured to move to the working position after the suction cup 23 has sucked the entire stack of cassette sheets 4, holding the stack of cassette sheets 4; and/or the holding pawl 24 is configured to move from the working position to the retracted position when the suction cup 23 releases the stacked cassette sheets 42 onto the feed mechanism 300. Based on this, during the process of moving the stack 4 away from the loading device 200, the suction cup 23 firstly sucks the stack 4, and then the supporting claw 24 supports the stack 4, so that the supporting claw 24 is more convenient to support the stack 4; in addition, in the process of placing the box pile 43 of the box pile 4 into the conveying mechanism 300, the supporting claw 24 is moved from the working position to the avoiding position, so that the supporting effect of the supporting claw 24 on the box pile 43 of the box pile 4 can be relieved, the box pile 43 conveniently falls onto the conveying mechanism 300 after the sucking disc 23 releases the sucking effect on the box pile 43, wherein the movement of the supporting claw 24 from the working position to the avoiding position can be performed before the sucking disc 23 starts to reduce the sucking force, or can be performed in the process of reducing the sucking force of the sucking disc 23, and in fact, the supporting claw 24 can leave the working position only before the sucking force of the sucking disc 23 is reduced to be incapable of sucking the box pile 43.

As an example of the holding claw 24 in the foregoing embodiments, referring to fig. 3, the holding claw 24 includes a holding rod 25 and a holding portion 26, and the holding portion 26 is connected to the robot arm 1 through the holding rod 25 and is used to contact with the cassette stack 4 to hold the cassette stack 4. Based on this, the supporting claw 24 can realize a stable and reliable supporting effect, which is beneficial to preventing the cassette stack 4 from toppling, falling or scattering in the process of carrying, and is beneficial to realizing a more efficient carrying process.

In the foregoing embodiments, in order to facilitate determining whether the holding claws 24 reach the working position, the carrying device 22 may include the in-place detecting member 27, and the in-place detecting member 27 detects whether the holding claws 24 move to the working position. For example, in some embodiments, the in-place detector 27 determines whether the tray jaw 24 is moved to the operative position by detecting whether the tray jaw 24 is in contact with the cassette stack 4. In this way, it is possible to automatically detect whether the holding pawl 24 has reached the working position, efficiently and accurately.

In addition, in the foregoing embodiments, in order to facilitate the carrying mechanism 2 to carry the cassette stack 4, the carrying mechanism 2 may include the in-position detecting member 28, the in-position detecting member 28 detects whether or not the cassette stack 4 to be carried exists on the loading device 200, and the carrying device 22 carries the cassette stack 4 after the in-position detecting member 28 detects that the cassette stack 4 to be carried exists on the loading device 200. In this way, the handling device 22 can perform handling tasks more accurately, which is advantageous for improving efficiency.

Next, the structure of the cassette supply system 10 will be described.

As previously described, in the present application, the cassette supply system 10 includes the feed mechanism 300 and the cassette handling apparatus 100 of any of the embodiments of the present application. Since the cassette handling apparatus 100 can handle the cassette stack 4 more efficiently, the cassette supply system 10 can supply the cassette stack 4 more efficiently, and can better meet the cassette demands of the packaging machine with a faster production speed.

In addition, referring to fig. 1-12, in some embodiments, the cassette supply system 10 includes not only the feed mechanism 300 and the cassette handling apparatus 100 of any of the embodiments of the present application, but also at least one of the cutting device 400, the escrow device 600, and the recovery device 500.

Wherein the cutting device 400 is used for cutting the wrapping paper 41 wrapped outside the stacked cassette 42 of the cassette stack 4 carried by the cassette carrying apparatus 100. Thus, the automatic cutting of the wrapping paper 41 can be realized, which is advantageous to further improve the efficiency and reduce the labor intensity compared with the manual cutting mode. The cutting device 400 may cut the wrapping paper 41 before the cassette handling device 100 releases the cassette stack 4 onto the feeding mechanism 300, so that the cassette handling device 100 may directly place the cassette stack 4 (i.e. the cassette stack 43) without the wrapping paper 41 on the feeding mechanism 300, and the taking is convenient. Moreover, the cutting device 400 cuts the wrapping paper 41 before the cassette handling apparatus 100 releases the cassette stack 43 onto the feeding mechanism 300, and also facilitates the handling device 22 to separate the wrapping paper 41 of the cassette stack 4 from the cassette stack 43 during the process of placing the cassette stack 43 on the feeding mechanism 300, because the cut wrapping paper 41 is more easily separated from the cassette stack 43 than the wrapping paper 41 that is not cut.

The temporary storage device 600 is used for temporarily storing the rest of the cassette stacks 4 transported by the transporting mechanism 2 before the transporting mechanism 2 transports the part of the cassette stacks 4 to the material transporting mechanism 300. Based on this, after the carrying mechanism 2 carries at least two stacks 4 away from the loading device 200, it is not necessary to send all the carried stacks 4 to the feeding mechanism 300 together, but a part of the stacks may be sent first, another part of the stacks may be temporarily stored in the temporary storage device 600, after the part to be sent first is put on the feeding mechanism 300, the carrying mechanism 2 carries the temporarily stored part of the stacks 4 away from the temporary storage device 600 and onto the feeding mechanism 300, so that mutual interference between the stacks 4 may be reduced, and it is more convenient for the carrying mechanism 2 to place the stacks 4 in order and accurately at the target discharging position of the feeding mechanism 300. Moreover, in the case where the cassette supply system 10 includes both the temporary storage device 600 and the cutting device 400, the handling mechanism 2 may temporarily store a part of the cassette stacks 4 in the handled cassette stacks 4 on the temporary storage device 600 before a part of the cassette stacks 4 in the handled cassette stacks 4 are handled to the cutting device 400, so that the two parts of the cassette stacks 4 may be prevented from interfering with each other during the cutting process, which is advantageous for realizing a more accurate and efficient cutting process.

The recovery device 500 is used for recovering the wrapping paper 41 of the stack 4 separated from the stacked sheets 42, and the conveyance device 22 places the stacked sheets 42 of the stack 4 on the feed mechanism 300, and then places the wrapping paper 41 of the stack 4 separated from the stacked sheets 42 into the recovery device 500. In this way, the clean and tidy site is maintained, and the subsequent centralized processing of the wrapping paper 41 is facilitated.

The present application will be further described with reference to the embodiments shown in fig. 1-12.

As shown in fig. 1 to 12, in this embodiment, the cassette supply system 10 includes a cassette handling apparatus 100, a loading device 200, a feeding mechanism 300, a cutting device 400, a recovery device 500, and a temporary storage device 600.

Wherein, the loading device 200 is used for storing the cassette stack 4 to be carried. As shown in fig. 1, in this embodiment, the loading device 200 is configured to be able to store a plurality of cassette stacks 4 to be handled. These stacks 4 are then discharged onto the loading device 200. Each cassette stack 4 corresponds to a different coordinate position. In order to facilitate the handling of the cassette handling device 100, in this embodiment, the cassette stacks 4 on the loading apparatus 200 may be numbered sequentially, and the cassette handling device 100 may be controlled to handle the cassette stacks 4 one by one in the order of the numbers. Specifically, in this embodiment, the corresponding placement positions of the plurality of cassette stacks 4 on the loading device 200 are sequentially labeled S1, S2, S3 … … SN in order, and then the cassette conveying apparatus 100 is controlled to convey in order. For example, the cassette handling apparatus 100 may first handle two cassette stacks 4 to the positions S1 and S2, and then handle the other two cassette stacks 4 to the positions S3 and S4 in order.

As shown in fig. 2, in this embodiment, the cassette stack 4 includes a wrapper 41 and a cassette stack 43 disposed within the wrapper 41 and wrapped by the wrapper 41. The stack 43 includes a plurality of stacked sheets 42. The stack 43 is wrapped circumferentially by the wrapper 41 to prevent the stacked sheets 42 from being spread apart. Specifically, as shown in fig. 2, in this embodiment, the top, bottom, left, and right sides of the pack 43 are all wrapped with the wrapper 41. Wherein the wrapping paper 41 is kraft paper. Kraft paper can provide a better bundling effect for the stack of sheets 43.

The feed mechanism 300 is used to feed the stack 43 of sheets to the packaging machine for the packaging process to use the sheets 42. As shown in fig. 1, in this embodiment, the feed mechanism 300 includes a belt 301. After the pack 43 is placed on the belt 301, the belt 301 conveys the pack 43 so that the pack 43 can be sent to the packaging machine.

The cassette handling apparatus 100 is used to handle the cassette stack 4 from the loading device 200 to the feeding mechanism 300 and place the cassette stack 43 of the cassette stack 4 on the feeding mechanism 300. In this embodiment, the cassette handling apparatus 100 is capable of handling two cassette stacks 4 at a time.

Specifically, as shown in fig. 3 to 5, in this embodiment, the cassette sheet handling apparatus 100 includes a supporting device 3, a robot arm 1, and a handling mechanism 2. The support device 3 is used for supporting the mechanical arm 1. The support device 3 comprises a base 31. The base 31 is provided with a turntable 32. The robot arm 1 is connected to the turntable 32 such that the robot arm 1 is rotatably arranged on the support device 3. The mechanical arm 1 further comprises at least two arm sections 11, the at least two arm sections 11 are sequentially connected, and the two adjacent arm sections 11 are connected through a joint 12, so that the arm sections 11 can rotate relatively. In this way, under the action of the turntable 32 and the joint 12, the mechanical arm 1 has a larger stroke and degree of freedom, and can better meet the requirements of the whole carrying process. The handling mechanism 2 is disposed at one end of the mechanical arm 1 far away from the supporting device 3 and moves along with the mechanical arm 1, so that under the driving of the mechanical arm 1, the handling mechanism 2 can be transferred between the material loading device 200, the temporary storage device 600, the cutting device 400, the material conveying mechanism 300 and the recycling device 500, and can be transferred between different positions of the material loading device 200, thereby completing the handling process.

More specifically, as can be seen from fig. 3, in this embodiment, the carrying mechanism 2 includes a mounting base 21, an in-position detecting member 28, and two carrying devices 22.

The mount pad 21 sets up in the one end that keeps away from strutting arrangement 3 of arm 1, realizes the setting of transport mechanism 2 in the one end that keeps away from strutting arrangement 3 of arm 1. In this embodiment, as shown in fig. 3, the mount 21 is a mounting plate and is generally rectangular. By providing the mounting seat 21, the mounting and fixing of the in-place detecting member 28 and the two carrying devices 22 are facilitated.

A position detecting member 28 is provided on the mount 21 for detecting whether or not the cassette stack 4 is present at the target position, so as to control whether or not the two conveying devices 22 perform cassette stack conveyance at the target position. Specifically, in this embodiment, the in-position detecting member 28 includes a photodetector, and is configured to detect whether or not the cassette stack 4 is present at the specified position when the conveyance mechanism 2 reaches the specified position. When detecting that the cassette stack 4 exists at the target position, the two conveying devices 22 operate to convey the cassette stack 4; if the fact that the cassette stack 4 does not exist at the target position is detected, the controller controls the mechanical arm 1 to move, the mechanical arm 1 drives the conveying mechanism 2 to move to the other position, the in-situ detection part 28 further detects whether the cassette stack 4 exists, and the operation of the two conveying devices 22 is controlled by the controller until the in-situ detection part 28 detects the cassette stack 4, and the cassette stack 4 is conveyed.

For example, when the mechanical arm 1 drives the carrying mechanism 2 to reach the S1 and S2 positions marked in advance, if the photoelectric detector detects that the two positions do not have the cassette stack 4, the controller controls the mechanical arm 1 to continue moving, from S1 and S2 to the S3 and S4 positions closest to S1 and S2, if the photoelectric detector detects that the cassette stack 4 exists in S3 and S4, carrying is performed, and if the photoelectric detector detects that the cassette stack 4 does not exist in S3 and S4, the mechanical arm 1 is controlled to continue moving, and searching for the cassette stack 4 is continued until the cassette stack 4 is found. It can be seen that the in-situ detecting member 28 provides a basis for the movement of the two carrying devices 22, so that the two carrying devices 22 can carry out the carrying action only after the in-situ detecting member 28 detects the cassette stack 4, which is also beneficial to improving the carrying accuracy and further improving the efficiency.

As can be seen from fig. 3, in this embodiment, the in-situ detecting member 28 includes two photodetectors, which facilitates the detection of the presence or absence of two stacks 4 at one time, improving efficiency.

Both handling devices 22 are used for handling the cassette stack 4. As shown in fig. 3, in this embodiment, both of the carrying devices 22 are provided on the mount 21 and are arranged side by side along the first direction. Moreover, both handling devices 22 are identical in construction, including a suction cup 23, a holding claw 24 and an in-place detecting member 27. For each carrying device 22, the suction cup 23 and the holding claw 24 are arranged side by side in a second direction perpendicular to the first direction, and the in-place detecting member 27 is provided on the holding claw 24. Thus, the handling mechanism 2 includes two suction cups 23, two holding claws 24, and two in-place detecting members 27 in total.

Wherein the suction cup 23 is configured to suction the cassette stack 4 by providing suction in a direction opposite to gravity. In this embodiment, the area of the single suction cup 23 for contact with the stack of cassette sheets 4 is large enough and the suction force of the single suction cup 23 is large enough that one suction cup 23, i.e. enough to suck one cassette stack 4. Thus, each of the handling devices 22 of this embodiment is capable of handling one cassette stack 4, thereby enabling the handling mechanism 2 of this embodiment to remove two cassette stacks 4 from the loading device 200 at a time.

Also, in this embodiment, the suction force of the suction cup 23 is variable. In particular, the suction force of the suction cup 23 may vary between a first value, a second value, a third value and a fourth value. The first value is the suction force that is able to suck the entire stack 4 (i.e. the combination of stack 43 and wrapper 41) and thus suck the entire stack 4. The second value is a value that can only suck the wrapping paper 41, cannot suck the stack 43, and further releases the suction force of the stack 43 while holding the suction wrapping paper 41. The third value is such that the entire stack 4 cannot be sucked, thereby releasing the suction of the entire stack 4. The fourth value is that the wrapping paper 41 cannot be sucked, and the suction force of the wrapping paper 41 is released. Wherein the second value, the third value, and the fourth value are all less than the first value, and the third value and the fourth value are all less than the second value. The third and fourth values may be 0, i.e. by making the suction force of the suction cups 23 0, the release of the entire stack 4 of sheets and the individual wrapper 41 is achieved. In this way, the suction cup 23 not only can suck up the whole stack 4, but also can temporarily store another stack 4 on the temporary storage device 600 before transporting the stack 4 to the cutting device 400 for cutting, and can separate the wrapping paper 41 from the stack 43, so that the stack 43 without the wrapping paper 41 directly falls onto the feeding mechanism 300, and can transport the wrapping paper 41 to the recycling device 500 solely by the feeding mechanism 300 and put into the recycling device 500 for recycling.

The holding claw 24 is used for carrying the cassette stack 4 together with the suction cup 23. As shown in fig. 3 and 5, in this embodiment, the supporting claw 24 includes a supporting rod 25 and a supporting portion 26, the supporting rod 25 is rotatably connected to the mounting seat 21, and the supporting portion 26 is disposed at an end of the supporting rod 25 away from the mounting seat 21 and protrudes toward a side of the same handling device 22 where the suction cup 23 is located. In this way, the holding pawl 24 is rotatably mounted on the mounting base 21 such that the holding pawl 24 can be rotated relative to the robot arm 1 between the operating position and the retracted position in order to hold or retract the cassette stack 4.

As can be seen from fig. 5, in this embodiment, in the working position (see the solid line in fig. 5), the supporting rod 25 is perpendicular to the surface of the mounting seat 21 facing the supporting claw 24, and is used for contacting with the side surface of the stack 4 to laterally restrain the stack 4, prevent the stack 4 from tilting to one side, increase the carrying stability, and the supporting portion 26 contacts with the bottom surface of the stack 4 to support the stack 4 upwards, so as to realize the supporting effect of the supporting claw 24 on the stack 4; while in the retracted position (see the solid line in fig. 4, the broken line in fig. 5 indicates the process of rotating toward the retracted position), the supporting rod 25 is parallel to the surface of the mounting seat 21 facing the supporting claw 24, the supporting claw 24 is entirely away from the stack of sheets 4, and neither the supporting rod 25 nor the supporting portion 26 is in contact with the stack of sheets 4. Thus, the working position is perpendicular to the avoiding position, and in the working process, the supporting claw 24 can be switched between the working position and the avoiding position only by rotating 90 degrees clockwise or anticlockwise, so that the operation is simple and convenient, and interference with the sucker 23 is not easy to occur. Of course, the retracted position may not be perpendicular to the operating position, for example, in other embodiments, the retracted position may be an inclined position that is inclined relative to the surface of the mounting base 21 facing the pawl 24, as shown in phantom in fig. 5.

As can be seen from fig. 4, in this embodiment, before the suction cup 23 starts to suck the stack of box sheets 4, but before the stack of box sheets 4 is sucked, the supporting claw 24 is far away from the suction cup 23 and is in the avoiding position, so that the supporting claw 24 can be effectively prevented from affecting the suction cup 23 to suck the stack of box sheets 4, the efficient operation of the production line is ensured, and the efficiency is improved; and after the sucking disc 23 sucks up the box piece stack 4, as shown in fig. 5, the supporting claw 24 rotates towards the direction close to the sucking disc 23 to reach the working position, so that the box piece stack 4 is supported, the box piece stack 4 is simultaneously subjected to the suction force of the sucking disc 23 and the supporting function of the supporting claw 24 in the carrying process, the box piece stack 4 can be effectively prevented from falling off, scattering or toppling over in the carrying process, the carrying stability can be effectively improved, and the carrying efficiency is improved.

When the box is required to be carried, the sucking disc 23 can be controlled to generate an adsorption force to suck the box stack 4 and lift the box stack 4 upwards, then the supporting claw 24 is controlled to rotate, the supporting claw 24 is controlled to rotate to a working position, and the supporting part 26 is inserted into the lower part of the box stack 4 and contacts with the bottom surface of the box stack 4 to support the box stack 4 below. Then, the mechanical arm 1 drives the carrying mechanism 2 to move, so that the carrying mechanism 2 can carry the cassette stack 4 to other positions.

Wherein, the setting position of the bearing part 26 on the supporting rod 25 can be adjusted to match with the box sheet stacks 4 with different sizes. For example, when the size of the stack 4 is small, the position of the supporting portion 26 on the supporting rod 25 can be adjusted in a direction approaching the mounting seat 21, so that the supporting portion 26 can still be engaged with the stack 4.

The in-place detector 27 is used to detect the position of the holding pawl 24 to determine whether the holding pawl 24 has reached the operating position. Specifically, in this embodiment, the in-place detecting member 27 includes a micro switch and is provided on the supporting lever 25 of the supporting claw 24, and determines whether the supporting claw 24 has reached the operating position by detecting whether the supporting lever 25 is in contact with the cassette stack 4. When the supporting rod 25 rotates to contact the cassette stack 4, the micro switch is triggered, the micro switch sends a signal to the controller, and the controller controls the supporting rod 25 to stop rotating according to the signal of the micro switch, so that the supporting claw 24 reaches and is kept at the working position, and the cassette stack 4 is supported. By adopting the micro switch as the in-place detection part 27, the detection accuracy can be effectively improved, the control sensitivity can be improved, and the supporting claw 24 can be accurately controlled to realize the supporting function.

As is apparent from the foregoing description, the cassette handling apparatus 100 of this embodiment can accurately and smoothly handle the cassette stacks 4, and the cassette handling apparatus 100 can handle two cassette stacks 4 at a time with high efficiency.

The cutting device 400 is disposed on a moving path of the carrying mechanism 2 from the material loading device 200 to the material conveying mechanism 300, and is used for cutting the packing paper 41 of the box piece stack 4, so that the box piece carrying device 100 can carry the box piece stack 4 to the cutting device 400 to cut the packing paper, then convey the box piece stack 4 with the packing paper 41 cut to the material conveying mechanism 300, and the box piece carrying device 100 can separate the box piece stack 43 from the packing paper 41 at the material conveying mechanism 300 conveniently, and place the box piece stack 43 and the packing paper 41 on the material conveying mechanism 300 and in the recycling device 500 respectively. As shown in fig. 1, in this embodiment, the cutting device 400 includes a cutting blade 401 provided on one side in the width direction of the feed mechanism 300 and located at the downstream end of the feed mechanism 300 in the conveying direction of the feed mechanism 300. Also, as can be seen from fig. 1 and fig. 7 to fig. 9, in this embodiment, the cutter 401 cuts one side surface of the wrapping paper 41, so that, as shown in fig. 9, after the wrapping paper 41 is cut, the side surface and the bottom surface drop, and the drop portions are located at two sides of the stack 43, while the top surface can still be absorbed by the suction cups 23, so that the stack 43 together with the cut wrapping paper 41 can be conveniently carried to the target discharging position of the feeding mechanism 300 by the stack carrying device 100, so that the stack 43 can still be restrained by the wrapping paper 41 to a certain extent in the process from the cutting device 400 to the target discharging position of the feeding mechanism 300, thereby being beneficial to prevent the stack 43 from loosening in the process from the cutting device 400 to the target discharging position of the feeding mechanism 300, and avoiding the efficiency being affected by the loosening of the stack 43.

The temporary storage device 600 is disposed on the moving path of the conveying mechanism 2 from the loading device 200 to the cutting device 400, and is used for temporarily storing one of the two conveyed stacks 4 before the two stacks 4 are conveyed to the cutting device 400 by the cassette conveying apparatus 100. As shown in fig. 6 and 7, in this embodiment, the temporary storage device 600 is configured as a temporary storage table and is disposed on a side of the feeding mechanism 300 in the width direction near the loading device 200. The cassette handling apparatus 100 is configured to, after the two cassette stacks 4 are removed from the loading device 200, reach the temporary storage device 600 first, place one of the two cassette stacks 4 on the temporary storage device 600, and then continue to handle the other to the cutting device 400 to cut the wrapping paper 41. The cassette handling apparatus 100 is further configured to, after the cut cassette stack 43 and the wrapping paper 41 of the cassette stack 4 are placed on the feeding mechanism 300 and the recovery device 500, remove the cassette stack 4 temporarily stored before from the temporary storage device 600, and continue the cutting and subsequent operations.

The recycling device 500 is used for recycling the wrapping paper 41. As shown in fig. 7 to 12, in this embodiment, the recycling apparatus 500 is a recycling container such as a tub or a box, which is placed near the temporary storage apparatus 600, so that the cassette handling device 100 is convenient for handling the cassette stack 4 on the temporary storage apparatus 600 after the wrapping paper 41 is placed in the recycling apparatus 500. The sheet cassette handling apparatus 100 is configured to, after one sheet cassette stack 43 is placed on the feeding mechanism 300, drive the wrapping paper 41 to move to the recovery device 500, release the suction force of the suction cup 23 on the wrapping paper 41, and drop the wrapping paper 41 into the recovery device 500, and then move the sheet cassette handling apparatus 100 to the temporary storage device 600 to handle the temporarily stored sheet cassette stack 4.

The operation of the cassette supply system 10 of this embodiment is described below in conjunction with fig. 4-12:

first, the carrying mechanism 2 of the cassette carrying apparatus 100 moves to above the loading device 200 and descends to a predetermined height slightly higher than the height of the cassette stack 4 by the robot arm 1 of the cassette carrying apparatus 100.

Thereafter, as shown in fig. 4, the cassette handling apparatus 100 marks and sequentially recognizes the cassette stack 4 on the loading device 200. Specifically, the two photodetectors on the mounting base 21 detect whether the cassette stack 4 with the corresponding label exists, if no cassette stack 4 exists at a certain label, the cassette handling device 100 searches sequentially and smoothly until the two cassette stacks 4 exist on the loading device 200, and the two suction cups 23 of the cassette handling device 100 start to suck the two cassette stacks 4 respectively. In the corresponding process, both the holding claws 24 of the cassette handling apparatus 100 are held in the retracted position.

After the suction force of the two suction cups 23 reaches the first value, the two suction cups 23 suck the two stacks 4, as shown in fig. 5, the two holding claws 24 of the cassette handling apparatus 100 immediately rotate clockwise, and stop rotating when the two micro switches detect the stacks 4, reach the working position, and hold and fix the two stacks 4.

Next, as shown in fig. 6, the cassette handling apparatus 100 carries two cassette stacks 4 away from the loading device 200, and conveys the two conveyed cassette stacks 4 to the temporary storage device 600 under the combined action of the turntable 32 and the joint 12, after reaching the temporary storage device 600, the holding claw 24 of one of the handling devices 22 of the cassette handling apparatus 100 rotates counterclockwise, leaves the working position, and the suction cup 23 of the same handling device 22 is closed under negative pressure, the suction force becomes 0, and the cassette stack 4 originally conveyed by the handling device 22 is released, so that the corresponding cassette stack 4 falls onto the temporary storage device 600. The suction cups 23 and the holding claws 24 of the other handling device 22 still hold and hold the stack of cassettes 4, respectively, during the corresponding process.

After one of the two conveyed stacks 4 is placed on the temporary storage device 600, as shown in fig. 7, the cassette conveying apparatus 100 conveys the other stack 4 to the right side of the paper cutting device 400, and causes the stack 4 to be rapidly scratched from the cutter 401 of the cutting device 400, so that the left side surface of the wrapping paper 41 of the stack 4 is cut, as shown in fig. 8 and 9 (the stack 43 is hidden in fig. 9 and 8).

Then, as shown in fig. 10, the cassette handling apparatus 100 carries the cut cassette stack 4 above the target placement position of the feeding mechanism 300 (in the drawing, the end of the feeding mechanism 300 away from the cutting device 400), then slowly lowers the cassette stack 4 to the target placement position of the feeding mechanism 300, during the corresponding process, the holding claw 24 that originally holds the cassette stack 4 rotates away from the working position, and the suction pressure of the suction cup 23 that originally holds the cassette stack 4 is reduced, so that the suction force of the suction cup 23 becomes smaller from the first value to the second value, and under the suction force, the suction cup 23 still holds the wrapping paper 41, but does not hold the cassette stack 43 any more, and the cassette stack 43 is released, so in this case, the belt 301 of the feeding mechanism 300 moves, and the cassette stack 43 can be transported to supply the packaging machine with the cassette 42.

Thereafter, as shown in fig. 11, the cassette conveying apparatus 100 moves the cut wrapping paper 41 to above the recovery device 500, and closes the negative pressure of the suction cup 23 sucking the wrapping paper 41, and discards the wrapping paper 41 into the recovery device 500, thereby completing recovery of the wrapping paper 41.

Next, as shown in fig. 12, the mechanical arm 1 of the cassette handling apparatus 100 drives the handling mechanism 2 to return to the temporary storage device 600, and the other cassette stack 4 stored before being handled by means of the suction cup 23 and the holding claw 24, and then the previous steps of cutting, stacking and packing paper discarding are repeated, so as to complete loading and feeding of the two cassette stacks 4 for single handling.

After loading and feeding of the two stacks 4 to be carried out once, the cassette carrying device 100 returns to the loading device 200 to search for the next stack 4, and in the searching process, the cassette carrying device 100 starts searching for the stack 4 downwards according to the label of the last existing stack 4. The previous steps are then repeated to complete the supply of the other two stacks 4.

It can be seen that the cassette supply system 10 of this embodiment has a simple structure and high automation, and can automatically complete multiple steps such as carrying, cutting, stacking, and recycling the packaging paper, and in particular, the cassette carrying device 100 thereof can carry two cassette stacks 4 at a time, and can neatly place the cassette stacks 43 of each cassette stack 4 on the feeding mechanism 300, so that the supply of the cassette stacks 4 can be efficiently completed, and the production efficiency can be effectively improved.

The cigarette packaging system includes a packaging machine and a cartoning frame supply system 10 of any of the embodiments of the present application. The feed mechanism 300 of the cassette supply system 10 delivers the cassette 42 of the cassette stack 4 to the packaging machine.

The foregoing description of the exemplary embodiments of the present application is not intended to limit the invention to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and scope of the invention.
