[0002] In the field of material production and packaging, packaging bags are increasingly used in daily production and life because of their good storage, transportation and portability for materials. Material packaging generally includes multiple links such as bag separation, bag retrieval, and bagging. The bag separation link is to store multiple packaging bags in a certain pattern in the mechanism to facilitate the subsequent bag retrieval link. Therefore, the mechanism that stores multiple packaging bags is generally called a bag separation mechanism.

[0003] The focus of traditional bag-splitting mechanisms is mainly on increasing the storage capacity of packaging bags and the ability to store packaging bags of different specifications. At the same time, in order to cooperate with the subsequent bag-taking operations, the bag-splitting mechanism is usually set up as an integral whole with other surrounding mechanisms. It is a fixed and immovable structure, which is not conducive to the maintenance and cleaning of the bag-splitting mechanism. Summary of the invention

[0004] The object of the present invention is to provide a bagging mechanism and a food packaging system to address the deficiencies in the prior art, so as to solve the problem that the existing bagging mechanism is difficult to maintain and clean.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In one aspect of an embodiment of the present invention, a bag dispensing mechanism is provided, referring to Figure 1 , including: a bag dividing part 101, a positioning part 102 and a rotating part 100; the rotating part 100 is rotatably connected to the bag dividing part 101, and a locking device is provided on the positioning part 102 and the bag dividing part 101. The locking device includes a locking state of locking the positioning part 102 and the bag dividing part 101, and an unlocking state of loosening the positioning part 102 and the bag dividing part 101 so that the bag dividing part 101 can rotate with the rotating part 100 as the axis.

[0032] For example, a bag-dividing mechanism that can be opened and closed is provided, so that the flexibility of the bag-dividing mechanism is greatly improved. It includes a bag-dividing part 101, a positioning part 102 and a rotating part 100. Among them, the fixed position of the rotating part 100 can be set according to the layout requirements of the packaging production line, and the positioning part 102 can be set according to the position where the bag-dividing part 101 needs to cooperate with the bag-taking mechanism to achieve accurate bag-taking, and the bag-dividing part 101 is rotatably connected to the rotating part 100, and the bag-dividing part 101 and the positioning part 102 are locked or unlocked by a locking device. For the convenience of description, the following will be combined with Figure 1One of the embodiments is described below.

[0033] Reference Figure 1 The rotating part 100 is a columnar body, one end of which is fixed on the ground, and the other end is connected to the bagging part 101 in a rotating manner, so that the bagging part 101 can realize horizontal rotation movement with the rotating part 100 as the rotating axis 1001. At the same time, in order to ensure the normal operation of the bagging part 101 in the normal production and packaging process (cooperating with other mechanisms), it is necessary to form a positioning when returning to the original position and a limit after returning to the original position, that is, a locking device is provided on the positioning part 102 of the columnar body and the bagging part 101, and one end of the positioning part 102 is also fixed on the ground. By bringing the bagging part 101 close to the positioning part 102, the two form an abutting relationship, completing the positioning process of the bagging part 101, and placing the locking device in a locked state, that is, completing the limit of the positioning part 102 on the bagging part 101, so that the bagging part 101 forms a stable connection relationship with the fixed and immovable positioning part 102.

[0034] In the actual production and packaging process, the bagging unit 101 and the positioning unit 102 are in a mutually limited state, that is, the locking device is in a locked state. When the bagging unit 101 needs to be maintained (repaired or cleaned) or bagged (the packaging bags in the bagging unit 101 are continuously reduced as the operation progresses and need to be replenished in time), Figure 1 As shown, the locking device is in an unlocked state, at which time the positioning portion 102 loses the locking restriction on the bagging portion 101. At this time, the bagging portion 101 can rotate with the rotating portion 100 as the rotating axis 1001, so that the bagging portion 101 is separated from the normal production process. After entering the maintenance area, it is convenient to cooperate with maintenance equipment, cleaning equipment, and maintenance personnel for maintenance and cleaning, further improving the maintenance convenience of the bagging portion 101 and shortening the maintenance time. At the same time, it can also avoid affecting other normal production processes during maintenance and cleaning. After rotating into the bagging area, the bagging operation can be carried out directly in the bag storage area in cooperation with the bagging equipment, thereby saving the process and cost of transporting the bag, and also improving the convenience and automation of bagging. By coordinating the bagging link and the cleaning link, food-grade cleaning and bagging integrated operations can also be achieved. When the bagging portion 101 needs to return to its position after maintenance or bagging, as Figure 2 As shown, the bag dispensing part 101 is rotated in the reverse direction to approach the positioning part 102. After the positioning is achieved by the positioning part 102, the locking device is placed in a locked state, so that the bag dispensing part 101 can be accurately returned to its original position and the stability when cooperating with the bag taking mechanism can be achieved.

[0035] It should be noted that the rotating part 100 can also be a cone, an irregular body, etc., the bagging part 101 can also be a cylinder, an irregular body, etc., and the positioning part 102 can also be a cylinder, an irregular body, etc. The specific settings can be reasonably set according to the actual needs of packaging production, and this application does not make specific limitations on it.

[0036] Optionally, the locking device includes a first clamping portion 103 and a second clamping portion 104 respectively provided on the positioning portion 102 and the bag dividing portion 101 , and the first clamping portion 103 and the second clamping portion 104 cooperate to clamp together to fix the bag dividing portion 101 to the positioning portion 102 .

[0037] For example, in order to improve the convenience of locking and unlocking, the locking device adopts a snap-on form, for example Figure 1 As shown in the figure, a first clamping part 103 is provided on the bag distributing part 101, and a second clamping part 104 is provided on the positioning part 102, and the two are clamped together to complete the locking state of the locking device. The clamping form can also ensure the connection stability and reliability of the bag distributing part 101 and the positioning part 102 in the locked state while having high locking and unlocking efficiency.

[0038] Optionally, a through slot 1031 is formed on the first clamping portion 103 , the second clamping portion 104 is rotatably connected to the positioning portion 102 , and the second clamping portion 104 rotates relative to the positioning portion 102 to fit into the through slot 1031 of the first clamping portion 103 .

[0039] like Figure 2 As shown, one of the forms of the first clamping part 103 and the second clamping part 104 is exemplarily given, that is, a through slot 1031 is formed on the first clamping part 103, and the second clamping part 104 and the positioning part 102 are rotatably connected, so that the second clamping part 104 is rotated to cooperate with the through slot 1031 on the first clamping part 103 to engage or disengage to complete the locking, limiting or unlocking separation of the bag-distributing part 101 and the positioning part 102. Among them, the rotation mode of the second clamping part 104 can be fixed-axis rotation, and the through slot 1031 on the first clamping part 103 is an L-shaped or arc-shaped groove, so that the second clamping part 104 is engaged from the notch during the fixed-axis rotation, and after rotating an arc trajectory, the locking device enters the locked state.

[0040] Optionally, the second clamping portion 104 includes a clamping piece 1041 and a limiting protrusion 1042; one end of the clamping piece 1041 is hinged to the positioning portion 102, and the other end is fixedly provided with the limiting protrusion 1042; the clamping piece 1041 is used to cooperate with the through groove 1031 to make the limiting protrusion 1042 abut against the first clamping portion 103.

[0041] like Figure 3As shown, another form of the first clamping part 103 and the second clamping part 104 is that the second clamping part 104 and the positioning part 102 are hingedly rotated, that is, fixed-point rotation, and the second clamping part 104 includes a clamping member 1041 and a limiting protrusion 1042, wherein the clamping member 1041 and the positioning part 102 form a hinged rotation, and the limiting protrusion 1042 is arranged at the other end of the clamping member 1041 away from the hinge end. The through slot 1031 arranged on the first clamping part 103 opens upward, and the clamping member 1041 can rotate in the vertical direction. When it is necessary to enter the locked state, after the first clamping part 103 on the bag distributing part 101 approaches the positioning part 102, first, the positioning part 102 forms a blocking and positioning effect, and then the vertically upright clamping part 1041 is controlled to rotate in the vertical direction, and the upward notch of the through slot 1031 on the first clamping part 103 is clamped into the through slot 1031, so that the part of the clamping part 1041 from the limiting protrusion 1042 to the hinged end is completely clamped into the through slot 1031. At this time, the limiting protrusion 1042 abuts against the side wall of the first clamping part 103. Thereby limiting the rotation of the bag distributing part 101. When it is necessary to unlock, the clamping part 1041 is controlled to rotate upward, so that the second clamping part 104 is completely separated from the first clamping.

[0042] It should be noted that, first, the slot of the through slot 1031 can also be facing downward, leftward, etc., and the rotation mode of the clamping member 1041 can also be horizontal rotation, etc., as long as the two can be engaged and clamped together so that the bagging portion 101 and the positioning portion 102 form a locking relationship (the bagging portion 101 cannot move relative to the positioning portion 102).

[0043] Second, the control of the card connector 1041 to rotate and snap in can be either manual control or automatic control. For example, a pressure sensor is provided at the position where the positioning part 102 blocks the bag dispensing part 101 from continuing to rotate. When the pressure sensor is connected to the controller, the controller controls the card connector 1041 to rotate. When the first card connector 103 is squeezed by the pressure sensor, the pressure sensor sends the pressure signal to the controller, and the controller controls the card connector 1041 to rotate into the through slot 1031 to complete the locking. When unlocking is required, the controller can receive the terminal command to control the card connector 1041 to rotate out of the through slot 1031 to complete the unlocking.

[0044] Optionally, a locking hole 1032 is formed on the first clamping portion 103; the second clamping portion 104 includes an elastic member 1043 and a clamping protrusion 1044, one end of the elastic member 1043 is fixedly connected to the positioning portion 102, and the other end is fixedly connected to the clamping protrusion 1044; the clamping protrusion 1044 includes a guiding inclined wall and a blocking wall, and the guiding inclined wall is used to guide the locking hole 1032 to accommodate the clamping protrusion 1044 so that the blocking wall abuts against the inner wall of the locking hole 1032.

[0045] As an example, another form of the first clamping portion 103 and the second clamping portion 104 is provided, such as Figure 4 As shown, an elastic member 1043 and a clamping protrusion 1044 are provided on the second clamping portion 104. The elastic member 1043 can be a spring sheet or a spring rod with deformation ability and good reset ability. The clamping protrusion 1044 is provided at the end of the elastic member 1043 away from the positioning portion 102 (the location of the clamping protrusion 1044 should be the location where the final bag-distributing portion 101 is accurately positioned). At the same time, a locking hole 1032 is formed on the first clamping portion 103 to match the position of the clamping member 1041 and the clamping protrusion 1044.

[0046] Reference here Figure 4 Combined with the structure of the locking device, the operation method of the bagging mechanism during bagging and maintenance is made: when the bagging part 101 is locked with the positioning part 102, that is, the clamping device is in a locked state, at this time, the clamping protrusion 1044 is completely accommodated in the locking hole 1032. When the bagging part 101 needs to be bagged or maintained, the spring plate or the clamping protrusion 1044 is pressed downward, so that the blocking wall of the clamping protrusion 1044 and the inner wall of the locking hole 1032 can no longer abut against the limit position, that is, the clamping protrusion 1044 is separated from the locking hole 1032. At this time, the bagging part 101 has one end as a rotating end and the other end as a free end, so as to realize the rotation with the rotating part 100 as the axis, so as to enter the bagging area or maintenance area, etc. When bagging or maintenance is completed, the bagging part 101 rotates in the opposite direction with the rotating part 100 as the axis. At this time, after the first clamping part 103 contacts the second clamping part 104, as the bagging part 101 continues to rotate, the first clamping part 103 will continue to approach the positioning part 102 along the guide wall of the clamping protrusion 1044, and the spring piece will be gradually pressed down and deformed as the guide wall acts as an inclined surface. When the locking hole 1032 of the first clamping part 103 completely accommodates the clamping protrusion 1044, the spring piece resumes its deformation. At this time, the blocking wall of the clamping protrusion 1044 abuts against the inner wall of the locking hole 1032, thereby limiting the movement of the bagging part 101 and completing the locking. The above-mentioned locking method is automatic locking, which simplifies the locking operation process. It should be noted that the clamping protrusion 1044 can be set upward ( Figure 4 As shown), it can also be over to the left or to the right, etc. The axis of the locking hole 1032 should be set accordingly to form reliable and stable locking and unlocking.

[0047] Optionally, the bag dividing mechanism further includes a linear drive fixedly connected to the positioning portion 102 , and the linear drive is used to drive the output shaft to abut against the end of the elastic member 1043 close to the positioning portion 102 to keep the locking protrusion 1044 away from the locking hole 1032 .

[0048] For example, in order to further improve the degree of automation and realize the automated control of the production process, a linear drive may be fixedly arranged on the positioning part 102, such as a linear drive motor, a cylinder, etc., which can realize a drive shaft or an output shaft to reciprocate in a linear direction. Figure 4 As well as the linear drive, a controller and a terminal can also be provided correspondingly. The operator can send instructions to the controller at the terminal, and the controller can judge accordingly and send the control instructions to the linear drive, so that when the locking device needs to be unlocked, the output shaft of the linear drive moves in a straight line to the side of the spring sheet with the clamping protrusion 1044, and abuts against the spring sheet at a position close to the positioning part 102 (i.e., between the first clamping part 103 and the positioning part 102, so as to avoid interference between the output shaft of the linear drive and the first clamping part 103 during the unlocking process, which affects the rotation of the bag-dividing part 101 and causes the unlocking to fail), so that the spring sheet is deformed, driving the clamping protrusion 1044 to disengage from the locking hole 1032, thereby completing reliable unlocking. After the unlocking is completed, the output shaft of the linear drive should be retracted to return the spring sheet to its original position and restore the deformation, so as to prepare for the next automatic locking.

[0049] Optionally, the rotating part 100 includes a rotating shaft 1001 and a bearing, and the rotating shaft 1001 is rotatably connected to the bag dividing part 101 through the bearing.

[0050] For example, Figure 1 As shown, the rotating part 100 includes a rotating shaft 1001 and a bearing fixedly connected to the ground, the outer wall of the bearing is fixedly connected to the bag-dividing part 101, and the inner wall of the bearing is fixedly connected to the rotating shaft 1001; or, the inner wall of the bearing is fixedly connected to the bag-dividing part 101, and the outer wall of the bearing is fixedly connected to the rotating shaft 1001. Thus, the rotating connection relationship between the bag-dividing part 101 and the rotating part 100 is completed. In addition, in order to further improve the degree of automatic control, the rotating shaft 1001 can also be connected to the rotating shaft 1001 of the motor, which can be directly connected or indirectly connected, and the motor is connected to the controller at the same time, and the terminal instruction is received by the controller, so as to control the motor according to the preset program to complete the rotation control of the bag-dividing part 101. It should also be noted that a preset program can be set in the controller, that is, after receiving the terminal instruction, the controller controls the locking device to unlock in sequence, rotates the bag-dividing part 101 to enter the bagging area or the maintenance area, and after completion, controls the bag-dividing part 101 to rotate in the reverse direction, and completes the locking with the positioning part 102 through the locking device. In order to further ensure the reliability of execution, sensors can also be set around the locking device to detect whether the locking device is in an unlocked state or a locked state. After confirming the state of the locking device, the controller controls whether the bag dividing part 101 rotates to avoid interference or damage to the mechanism when continuing to execute the next instruction due to incomplete unlocking or incomplete locking.

[0051] Optionally, the bag distributing unit 101 includes a bracket rotatably connected to the rotating unit 100 and a plurality of bag storage bins 1011 arranged on the bracket, and the bag storage bins 1011 include a bag taking port 1013 and a bag placing port 1012 .

[0052] For example, Figure 1 As shown, the bag distributing unit 101 includes a bracket rotatably connected to the rotating unit 100 at one end, and a plurality of bag storage bins 1011 arranged in a straight line on the bracket. Figure 1 There are 12 bag storage bins 1011 in the bag storage bin 1011. A bag placing port 1012 is provided at the upper end of the bag storage bin 1011, and a bag taking port 1013 is provided at the opposite lower end, so as to cooperate with the replacement mechanism to complete bag taking from the lower part. In order to further ensure the neatness of bag filling and ensure the accurate bag taking of the replacement mechanism, a bag poking mechanism 105 can also be provided on the bracket. Specifically, a slide rail can be provided at the upper end of the bracket, and a bag poking rod can be provided on the slide rail. The bag poking rod can be used to squeeze the packaging bags so that they are neatly arranged in the bag storage bin 1011.

[0053] Optionally, a weight reduction groove 1014 is also provided on the side wall of the bag storage bin 1011 .

[0054] For example, Figure 1 As shown, a weight-reducing groove 1014 may be further provided on the side wall of the bag storage bin 1011, thereby further reducing the weight of the bag distributing part 101, reducing the bearing load of the rotating part 100, and extending the service life of the entire bag distributing mechanism.

[0055] Another aspect of the embodiments of the present invention further provides a food packaging system, comprising any one of the above-mentioned bag dividing mechanisms.

[0056] For example, the above-mentioned bag-splitting mechanism is applied to a food packaging system, and a bag-loading mechanism, a bag-removing mechanism, and a maintenance and cleaning mechanism may also be provided in the system. The bag-splitting mechanism is rotated to cooperate with the bag-loading mechanism in the bag-loading area to complete bag-loading, and the maintenance and cleaning mechanism is used to complete maintenance and cleaning operations. Then, the locking and positioning are completed by rotating back to the original position in cooperation with the positioning part 102. This ensures that the bag-removing mechanism can accurately and smoothly complete the bag-removing, and then cooperates with other mechanisms to complete the entire food packaging operation process. It can effectively shorten the maintenance and inspection time of the food packaging process and increase the packaging efficiency of the food packaging system. At the same time, automated packaging operations are realized.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
