Description

Technical Field

[0001] The utility model relates to a paper bag packaging machine, in particular to a bag body stacking device of the paper bag packaging machine. Background Art

[0002] Paper bags are environmentally friendly packaging and are widely loved by consumers. Paper bag packaging machines are used to pack the prepared paper bags, so the paper bags should be stacked before packing.

[0003] In the prior art, after paper bags are produced by a bag making machine, they are sent out one by one through a conveyor belt and are manually stacked and collected, which is labor-intensive and inefficient. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the utility model provides a bag stacking device for a paper bag packaging machine which automatically stacks and integrates bags and lays a foundation for subsequent automatic bag packing.

[0005] To solve the above technical problems, the utility model is solved through the following technical solutions: a bag stacking device of a paper bag packaging machine, comprising a material receiving platform, a bag turning mechanism and a bag moving and stacking mechanism; the material receiving platform has a bag turning station and a bag stacking station, and the material receiving platform has a first channel; the bag turning mechanism is arranged on the bag turning station, and the bag turning mechanism includes a turning component and a bag turning driving component for driving the turning component to rotate, and the turning component has a second channel, and the turning component can turn the horizontal bag into a vertical bag. When the bag body on the flipping component is a vertical bag body, the second channel of the flipping component is connected to the first channel of the material receiving platform to form a bag body integration channel; the bag body material moving and stacking mechanism includes a lifting bag pushing rod group that enters the second channel to push the bag body and a lifting limit rod group that cooperates with the lifting bag pushing rod group to transfer the bag body, the lifting bag pushing rod group and the lifting limit rod group are arranged relatively to each other on the material receiving platform, the lifting bag pushing rod group and the lifting limit rod group are respectively connected to the driving mechanism, and the driving mechanism respectively drives the lifting bag pushing rod group and the lifting limit rod group to move in the bag body integration channel.

[0006] Because horizontal bags can only be stacked upwards, the more bags there are, the higher the height will be, which is inconvenient for subsequent packaging. However, increasing the number of vertical bags will only change the overall length, which is convenient for subsequent stacking and packaging. The flipping component of the utility model rotates to flip the horizontal bag into a vertical bag, and the vertical bag is convenient for packaging. When the bag is flipped into a vertical bag, the lifting bag pushing rod group rises to the second channel to push the bag out. The lifting limit rod group and the lifting bag pushing rod group are fixed in the integration channel. The two cooperate to integrate the bag and clamp it to the bag stacking station, leaving the bag flipping station vacant to facilitate the flipping component to flip the subsequent horizontal bag. The lifting limit rod group and the lifting bag pushing rod group cooperate to integrate the bag, realizing automatic bag integration. The utility model automatically stacks and integrates the bag, and the bag changes from horizontal to vertical, reducing the difficulty of packing and packaging the bag pile, and laying the foundation for subsequent automatic packaging of the bag.

[0007] Preferably, the flipping component is a swing claw, or the flipping component is a rotating bracket, and the rotating bracket is cross-shaped.

[0008] Preferably, the lifting and pushing rod assembly is slidably mounted on a first mounting frame; the lifting and limiting rod assembly is slidably mounted on a second mounting frame; the driving mechanism includes a first pushing power source and a second pushing power source, the first pushing power source being in transmission connection with the first mounting frame, and the second pushing power source being in transmission connection with the second mounting frame. The lifting and pushing rod assembly moves up and down to avoid the bags, and the simultaneous lifting of the lifting and pushing rod assembly and the lifting and pushing rod assembly can release the integrated bag stack, laying the foundation for subsequent bag packaging.

[0009] Preferably, the inlet end of the bag-turning mechanism is connected to the outlet end of the bag-conveying mechanism. The bag-conveying mechanism is used to convey horizontal bags into the bag-turning mechanism. The material receiving surface of the bag-turning mechanism is no higher than the material support surface of the bag-conveying mechanism. The bag-conveying mechanism connects the paper bag packaging machine and the paper bag production equipment. The material receiving surface no higher than the material support surface can ensure smoother conveying.

[0010] The bag conveying mechanism includes a conveyor belt for conveying horizontal bags, and the at least two flipping parts are provided, and the conveyor belt is arranged between the flipping parts. The conveyor belt conveys the bags, and the structure is simple.

[0011] In addition, the bag conveying mechanism includes a supporting platform and pushing components arranged on both sides of the supporting platform. The pushing components are respectively connected to a reversing driving component that drives them to avoid the bag and a longitudinal pushing driving component that drives them to push the bag. The reversing driving component drives the pushing component to avoid the bag, and the longitudinal driving component drives the pushing component to push the bag into the flipping component.

[0012] Further, the avoidance driving component is a lateral driving component. The avoidance driving component drives the pusher component to move left and right respectively, so as to avoid the bag body when the pusher component returns to its original position.

[0013] Further, the avoidance driving component is a lifting driving component. The avoidance driving component drives the pusher component to rise, so as to avoid the bag body when the pusher component returns to its original position.

[0014] On the basis that the avoidance driving component is a lateral driving component, the pusher component includes a side stop gauge part and a bag pushing part, and the side stop gauge part is perpendicular to the bag pushing part. The side stop gauge part can correct and align the offset bag body, and the bag pushing part pushes the bag body. The perpendicularity of the two ensures that the bag body does not deviate.

Detailed Embodiment

[0024] The present utility model will be further described in detail below in conjunction with the drawings and embodiments. The X-axis direction is horizontal, that is, the left and right direction, the Y-axis is longitudinal, that is, the front and back direction, and the Z-axis is vertical, that is, the up and down direction.

[0025] A bag stacking device for a paper bag packaging machine includes a material receiving platform 1, a bag flipping mechanism, and a bag material transfer and stacking mechanism 3. The material receiving platform 1 has a bag flipping station and a bag stacking station. The material receiving platform 1 has a first channel and a plurality of load-bearing rods arranged at intervals. The load-bearing rods are arranged at intervals, and the gaps between the load-bearing rods form the first channel. The bag flipping mechanism is arranged at the bag flipping station. The bag flipping mechanism includes a flipping component 2 and a bag flipping drive for driving the flipping component 2 to rotate. The flipping component 2 is rotatably mounted on a frame. The flipping component 2 can flip a horizontal bag into a vertical bag (i.e., the bag is flipped 90°). Because horizontal bags can only be stacked upward, an excessive number of bags will result in an excessive height, which is not conducive to subsequent packaging. Increasing the number of vertical bags only changes the overall length, making it easier to move and more convenient for subsequent packaging. Therefore, vertical bag stacking and packaging is selected. The flipping component 2 has a space for accommodating bags, within which horizontally placed bags are placed. The flipping component 2 has a second channel 21. When the bag on the flipping component 2 is a vertical bag, the second channel 21 of the flipping component 2 communicates with the first channel of the material receiving platform 1 to form a bag integration channel. The flipping component 2 can be a swing claw with a second channel 21 therein. Specifically, there can be several swing claws, with adjacent swing claws connected by a rotating shaft, which is fixedly connected to a swing arm 22. A bag-flipping drive is provided on the frame, and the swing arm 22 is in transmission connection with the bag-flipping drive. The bag-flipping drive can be a motor or a cylinder, which telescopically drives the swing claw to swing. Alternatively, the flipping component 2 can be a rotating bracket, which is cross-shaped.

[0026] The bag body material moving and stacking mechanism 3 includes a lifting bag pushing rod group 31 that enters the second channel 21 to push the bag body and a lifting limit rod group 32 that cooperates with the lifting bag pushing rod group 31 to transfer the bag body. The bag body material moving and stacking mechanism 3 can be arranged above or below the material receiving platform 1. In this embodiment, the bag body material moving and stacking mechanism 3 is arranged below the material receiving platform 1, and the lifting bag pushing rod group 31 and the lifting limit rod group 32 are relatively arranged on the material receiving platform 1. Specifically, the lifting bag pushing rod group 31 is composed of several bag pushing rods, and the lifting bag pushing rod group 31 is slid up and down on the first mounting frame, and the first mounting frame is provided with a vertical first guide rail. The first lifting power source drives the lifting bag pushing rod group 31 to move up and down on the first guide rail. The lifting bag pushing rod group 31 rises and enters the second channel 21, and can push out all the vertical bags in the flipping component 2. The lifting limit rod group 32 is composed of several limit rods, which are slid up and down on the second mounting frame. The second mounting frame has a vertically arranged second guide rail. The second lifting power source drives the lifting limit rod group 32 to move up and down on the second guide rail. The lifting limit rod rises and presses against the vertical bag body to prevent the vertical bag body from collapsing.

[0027] The driving mechanism includes a first pushing power source and a second pushing power source, the first pushing power source is connected to the first mounting frame by transmission, and the second pushing power source is connected to the second mounting frame by transmission. The lifting bag pushing rod group 31 and the lifting limit rod group 32 are respectively connected to the driving mechanism by transmission, and the driving mechanism drives the lifting bag pushing rod group 31 and the lifting limit rod group 32 to move in the bag body integration channel respectively, and the first pushing power source drives the lifting bag pushing rod group 31 on the first mounting frame to move back and forth. The pushing power source can be a motor or a cylinder. In this embodiment, the first pushing power source is a motor, and the first mounting frame is connected to the screw driven by the first pushing power source through a bearing. The first pushing power source drives the lifting bag pushing rod group 31 on the first mounting frame to move back and forth. The second pushing power source is connected to the second mounting frame by a screw. The lifting bag pushing rod group 31 and the lifting limit rod group 32 cooperate to clamp the vertical bag from the bag body flipping station to the bag body stacking station. The horizontal bags are flipped 90 degrees during the conveying process and then stacked. This process can be done by conveying individual bags one by one, but in order to improve work efficiency, multiple bags are usually conveyed at a time and then flipped and stacked in batches.

[0028] To enable automatic feeding of the bag-tumbling mechanism, the inlet end of the bag-tumbling mechanism engages with the outlet end of the bag-conveying mechanism 4. The bag-conveying mechanism 4 is used to deliver bags into the bag-tumbling mechanism. The material receiving surface of the tumbling component 2 engages with the conveying surface of the bag-conveying mechanism 4, and the material receiving surface of the bag-tumbling mechanism is no higher than the material support surface of the bag-conveying mechanism 4. The bag-conveying mechanism 4 can be implemented in various ways. For example, the bag-conveying mechanism 4 includes a conveyor belt for conveying horizontal bags, and the tumbling components 2 have at least two conveyor belts disposed between the tumbling components 2. The conveyor belt directly delivers the horizontal bags into the space between the tumbling components 2, simplifying the conveying method. To simultaneously transport multiple bags, push plates can be provided on the conveyor belt. Alternatively, the bag-conveying mechanism 4 includes a supporting platform 41 and pusher components 42 disposed on either side of the supporting platform 41. The pusher components 42 are transmission-connected to a reversing drive component 44 for driving the pusher to reversing the bag and a longitudinal pusher drive component 43 for driving the pusher to push the bag. There are multiple ways to avoid the pusher 42. For example, the avoidance drive component 44 is a lifting drive component, which drives the pusher 42 to rise to avoid the bag. The longitudinal pusher drive component 43 is arranged above the pusher platform. A first movable seat is provided above the support platform 41. The first movable seat is connected to the longitudinal pusher drive component 43. The avoidance drive component 44 is arranged on the first movable seat to drive the lifting seat to move up and down. The pusher 42 is arranged on the lifting seat. Alternatively, the avoidance drive component 44 is a horizontal drive component, which drives the pushers 42 on both sides to perform left-right symmetrical movements. The longitudinal pushing drive component 43 is arranged on the second movable seat, and pushing guide rails are provided on both sides of the frame. The pushing guide rails are arranged longitudinally, and the second movable seat is slidably arranged on the pushing guide rails. The longitudinal pushing drive component 43 can be a linear drive method such as a cylinder, a belt drive mechanism or a screw drive mechanism. The longitudinal pushing drive component 43 is connected to the second movable seat. The avoidance drive component 44 can be arranged between the second movable seat and the pushing component 42, or the pushing component 42 can be arranged on the mounting plate, and there is a guide rod between the second movable seats on both sides. The mounting plate is slidably arranged on the guide rod, and there is a fixed plate between the mounting plate and the second movable seat. The avoidance drive component 44 is arranged between the fixed plate and the mounting plate, driving the mounting plate to move left and right along the guide rod. Multiple pushing components 42 can be arranged on the mounting plate, and one avoidance drive component 44 drives multiple pushing components 42 to move, thereby improving the bag conveying efficiency while ensuring low costs. Based on the fact that the avoidance drive component 44 is a horizontal drive component, the pushing component 42 includes a side stop portion 421 and a bag pushing portion 422, and the side stop portion 421 and the bag pushing portion 422 are perpendicular to each other. When the avoidance drive component 44 drives the pushing component to move toward the bag from both sides, it can correct the skewed bag, prevent the bag from shifting, and ensure that the bag is subsequently delivered in an orderly manner. Example 1

[0029] The conveyor belt is connected to the paper bag making machine. After the conveyor belt sends the bag body into the flipping component 2, it stops conveying. The flipping component 2 flips 90° to convert the bag body in the lying state into a vertical state. The lifting and pushing bag rod group 31 and the lifting limit rod group 32 move towards the flipping component 2 through the first channel. The lifting and pushing bag rod group 31 moves to wait below the flipping component 2 and then rises into the second channel 21. When the flipping component 2 places the bag body upright on the material receiving platform 1, the lifting limit rod group 32 is in the rising state, resisting the vertical bag body to prevent the vertical bag body from collapsing. The lifting and pushing bag rod group 31 rises into the second channel 21. The lifting and pushing bag rod group 31 and the lifting limit rod group 32 cooperate to clamp the vertical bag body and push the bag body out of the flipping component 2 and move it to the bag stacking station. When the next batch of bag bodies needs to be flipped, the lifting and pushing bag rod group 31 and the lifting limit rod group 32 move the bag body on the bag stacking station towards the bag flipping station. The next batch of bag bodies is in a vertical state. The lifting and pushing bag rod group 31 moves in front of the bag body on the flipping component 2 and descends to avoid. The lifting limit rod group 32 integrates the bag bodies. Then the lifting and pushing bag rod group 31 enters the second channel 21. The lifting and pushing bag rod group 31 and the lifting limit rod group 32 cooperate to move the integrated bag bodies to the bag stacking station. Such repeated actions are carried out until a certain number of bag bodies are reached. The vertical bag bodies are automatically stacked, reducing the labor intensity and at the same time laying a foundation for subsequent automatic packing. Embodiment 2

[0030] The pushing platform is connected to the bag making machine. A single bag body or a small batch of bag bodies enter the material supporting platform 41. The pushing components 42 on both sides move relatively. The side stop gauge parts 421 and the bag pushing parts 422 perpendicular to each other correct the bag bodies, and the bag pushing parts 422 push the bag bodies into the receiving surface of the flipping component 2. The subsequent flipping and stacking actions are the same as those in Embodiment 1.

[0031] After the bag body enters the flipping component 2, the pushing component 42 returns to its original position and pushes back and forth like this. Embodiment 3

[0032] The pushing platform is connected to the bag making machine. A single bag body or a small batch of bag bodies enter the material supporting platform 41. The pushing components 42 on both sides descend to the rear of the bag body. The longitudinal pushing drive component 43 drives the pushing components 42 to push the bag bodies into the flipping component 2. The subsequent flipping and stacking actions are the same as those in Embodiment 1. After the bag body enters the flipping component 2, the pushing component 42 returns to its original position and pushes back and forth like this.
