Technical solutions according to the embodiments of the present application will be described clearly and completely as follows in conjunction with the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All the other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative work belong to the scope of protection of the present application.
When used for material packaging, a packaging bag is opened first, and then the material to be packaged is put into the packaging bag. Finally, an opening of the packaging bag is sealed. Since the packaging bag is of a light and soft material, an opening of the packaging bag is generally in a closed state. When the packaging bag is opened manually, the opening of the packaging bag has to be pulled open with a friction force. A human hand may easily slip on the packaging bag, therefore the efficiency of manual bag opening is relatively low. For large-scale production lines, manual bag opening and manual material filling are not appropriate any more. Hence, bag packaging equipment has emerged. The existing bag packaging equipment includes a bag loading apparatus and a bag receiving apparatus. The bag loading apparatus opens the opening of the packaging bag and loads the packaging bag onto the bag receiving apparatus. For example, suction cups suck two sides of the opening of the packaging bag, and move in opposite directions, thus the opening of the packaging bag is open. Then, the suction cups move close to the bag receiving apparatus to put the packaging bag onto the bag receiving apparatus. The bag receiving apparatus keeps the opening of the packaging bag in an opened state, and the material is manually filled into the packaging bag. Then, the packaging bag is taken off the bag receiving apparatus and is sealed, thereby the packaging of the material is finished. With the existing bag packaging equipment, the opening of the packaging bag can be opened faster, and the operation efficiency has been improved. However, when the material is produced by the production lines in large batches, the efficiency of the manual material filling is relatively low, and as a result, the packaging cannot catch up with the production lines.
As shown in
As shown in
The bag loading apparatus 300 includes a bag placement mechanism 301, a bag conveying mechanism 302, and a bag transfer mechanism 303 that are arranged on the frame 100 along the material filling direction. The bag placement mechanism 301 is configured to store the packaging bag. The bag conveying mechanism 302 is configured to convey the packaging bag inside the bag placement mechanism 301 to the bag transfer mechanism 303. The bag transfer mechanism 303 is configured to load the packaging bag onto a bag holder 402. The bag loading apparatus 300 may load the packaging bag onto the bag holder 402 along a horizontal direction or a vertical direction.
The bag receiving apparatus 400 includes a support assembly 401 and multiple bag holders 402. The support assembly 401 is rotatably arranged on the frame 100, and the multiple bag holders 402 are symmetrically arranged on the support assembly 401 with respect to a rotation axis of the support assembly 401. The rotation axis of the support assembly 401 is perpendicular to the material filling direction, and multiple bag holders 402 may be provided along the rotation axis of the support assembly 401.
The support assembly 401 may be a support plate or a support rod. One or more support plates may be provided, or one or more support rods may be provided. When the support assembly 401 employs the support plate, a lightening hole is provided on the support plate to reduce the moment of inertia of the rotating support plate. The rotating support assembly 401 drives the multiple bag holders 402 to rotate, such that a position of each bag holder 402 switches between a bag loading station and a material filling position. The bag holder 402 can keep an opening of the packaging bag open. In an embodiment, each bag holder 402 includes a first moving plate, a second moving plate, and a linear motor that are arranged on the support plate. The first moving plate and the second moving plate are arranged on the support plate in a slidable manner, and the linear motor drives the first moving plate and the second moving plate to move close to or away from each other. Alternatively, each bag holder 402 is a mechanical clamping body. The mechanical clamping body includes two clamping members that are symmetrically arranged. The two clamping members clamp the packaging bag at two ends of an outer side of the opening of the packaging bag. The two clamping members move towards each other to squeeze the packaging bag to open the opening of the packaging bag, and move away from each other to stretch the packaging bag to close the opening of the packaging bag. After the material is filled, the clamping members release the packaging bag, such that the packaging bag can be conveyed to other positions.
When each bag holder 402 rotates to the bag loading station along with the support assembly 401, the linear motor drives the first moving plate and the second moving plate to move close to each other, such that the first moving plate and the second moving plate can be easily inserted into the packaging bag. At the bag loading station, the bag loading apparatus 300 opens the opening of the packaging bag and loads the packaging bag onto the first moving plate and the second moving plate, such that the first moving plate and the second moving plate are at least partially located inside the packaging bag. Then the linear motor drives the first moving plate and the second moving plate to move away from each other and contact the packaging bag, such that the first moving plate and the second moving plate can keep the opening of the packaging bag open.
Alternatively, the first moving plate and the second moving plate are hingedly connected to the support assembly 401. An air cylinder is provided on the support assembly 401, and the air cylinder drives the first moving plate and the second moving plate to rotate close to or away from each other at the same time, thereby achieving the above functions.
The support assembly 401 rotates to make the first moving plate and the second moving plate move to the material filling position, so that the packaging bag is moved to the material filling position.
At the material filling position, the opening of the packaging bag faces the material filling apparatus 200, and the material filling apparatus 200 fills the material into the packaging bag. In an embodiment, the material filling apparatus 200 is a conveyor belt, and the material to be packaged is conveyed to the opening of the packaging bag and is filled into the packaging bag on the conveyor belt. In an embodiment, the material filling apparatus is a robotic arm, and the robotic arm grabs the material to be packaged and puts the material into the packaging bag.
After the material is filled into the packaging bag, the linear motor drives the first moving plate and the second moving plate to move close to each other, such that the packaging bag stops contacting the first moving plate and the second moving plate. The packaging bag is conveyed to the sealing mechanism 600 automatically or manually.
The sealing mechanism 600 seals the packaging bag getting off the bag receiving apparatus 400. Then the packaging bag is conveyed to a next workstation by the output mechanism 500. The sealing mechanism 600 may be a heat sealer or a press sealer, which is determined according to the type of the packaging bag.
The output mechanism 500 may be a conveyor belt, a turntable, a robotic arm or the like.
The rotation axis of the support assembly 401 is perpendicular to the X direction. In this way, a direction of the opening of the packaging bag can be regulated by a rotating angle of the support assembly 401. In an embodiment, as shown in
With more bag holders 402, the packaging efficiency can be further increased. In an embodiment, referring to
In an embodiment, when the support assembly 401 only includes a first support plate 4011, the bag holder 402 loaded with the packaging bag is at the bag loading station and the second material filling station. When the packaging bag at the second material filling station is filled with the material and gets off the bag holder 402, the bag holder 402 at the bag loading station rotates by 180° to the second material filling station for material filling.
When the support assembly 401 further includes a second support plate 4012, where an angle between the second support plate 4012 and the first support plate 4011 along a circumferential direction of the rotation axis is 90°, the bag holder 402 on the first support plate 4011 loaded with the packaging bag is at the bag loading station and the second material filling station, and the bag holder 402 on the second support plate 4012 loaded with the packaging bag is at the first material filling station. After the material is filled into the packaging bag on the first support plate 4011 at the second material filling station, the packaging bag on the second support plate 4012 at the first material filling station rotates by 90° to the second material filling station for material filling.
Further, based on the above embodiments, an angle between each two adjacent support plates along the circumferential direction of the rotation axis may be regulated by those skilled in the art into 30°, 45°, 60°, or 90°, which is not described in detail herein.
Similarly, more bag holders 402 on the support assembly 401 lead to a higher operation efficiency of the packaging equipment. For example, when the multiple bag holders 402 are provided along an axial direction of the rotation axis, multiple bag loading apparatuses 300 and multiple material filling apparatuses 200 are provided on the frame 100 in one-to-one correspondence to the multiple bag holders 402, such that multiple packaging bags are loaded at one time, so as to further enhancing the packaging efficiency.
In an embodiment, referring to
In an example, when the multiple bag holders 402 on the first end plate 4014 and the second end plate 4015 are rotating along with the connecting plate 4013 to the bag loading station, the packaging bag may be loaded onto the multiple bag holders 402 along the vertical direction. The bag loading apparatus 300 may load the packaging bag onto the bag holder 402 along a direction away from the ground, or along a direction towards the ground.
When the multiple bag holders 402 are arranged on the support assembly 401 symmetrically with respect to the rotation axis of the support assembly 401, and the multiple bag holders 402 can be switched between the bag loading station and the material filling station, the bag receiving apparatus may occupy a relatively large space and may have a large moment of inertia, and therefore more energy is consumed for driving the bag receiving apparatus to rotate.
A technical solution is provided according to an embodiment of the present application to solve the above problem. Retractable packaging machinery according to an embodiment of the present application includes a frame 100, and a material filling apparatus 200, a bag loading apparatus 300, and a bag receiving apparatus 400 that are arranged on the frame 100. The structures of the frame 100 and the material filling apparatus 200 may be provided referring to the above embodiments.
In an example, the bag receiving apparatus 400 includes multiple bag holders 402 and a retractable mechanism. The retractable mechanism is rotatably arranged on the frame 100, and the multiple bag holders 402 are arranged on the retractable mechanism symmetrically with respect to a rotation axis of the retractable mechanism. The retractable mechanism is configured to drive the multiple bag holders 402 to move close to or away from the rotation axis. In an example, the retractable mechanism may be a pneumatic push rod, a hydraulic cylinder, or a cam driven by a motor. A rotation shaft 4016 is provided on the frame. The pneumatic push rod is fixed on the rotation shaft 4016, and a telescopic rod of the pneumatic push rod is fixedly connected to the multiple bag holders 402. When the pneumatic push rod rotates along with the rotation shaft 4016 on the frame 100, the multiple bag holders 402 rotates along with an air cylinder. When the telescopic rod of the pneumatic push rod moves back and forth, the multiple bag holders 402 moves away from or close to a rotation axis of a base of the air cylinder. In another embodiment, the retractable mechanism includes a guide structure, a first support plate 4011, a second support plate 4012, and a linear actuator. The guide structure may be a slide rail, a guide rod or the like, and the linear actuator may be an air cylinder, a hydraulic cylinder, a linear motor or other devices that can output a linear motion. For example, the guide structure is a guide rod. The guide rod is fixedly connected to the rotation shaft 4016, and the air cylinder is fixed on the guide rod. The multiple bag holders 402 are mounted on the first support plate 4011 and the second support plate 4012, and the first support plate 4011 and the second support plate 4012 cooperate with the guide rod in a slidable manner. A telescopic rod of the air cylinder is connected to the first support plate 4011 and the second support plate 4012. The air cylinder moves back and forth to drive the first support plate 4011 and the second support plate 4012 to slide on the guide rod, thereby driving the multiple bag holders 402 to slide on the guide rod.
The retractable mechanism is rotatably arranged on the frame, and the rotation axis of the retractable mechanism is perpendicular to the material filling direction of the material filling apparatus 200. During rotation of the multiple bag holders 402 from the bag loading station to the material filling station, the retractable mechanism drives a distance between the multiple bag holders 402 at two sides of the rotation axis to decrease first and then increase, which makes a radius of rotation of the bag receiving apparatus 400 decrease first and then increase. In this way, a space occupied by the bag receiving apparatus 400 is saved, and a moment of inertia of the bag receiving apparatus 400 can be temporarily reduced, thereby reducing energy consumption for driving the bag receiving apparatus 400, and improving the using safety of the packaging equipment.
In an embodiment, as shown in
Each of the first support plate 4011 and the second support plate 4012 may be a support plate or a support rod. The first support plate 4011 and the second support plate 4012 may be connected to the rotation shaft 4016 through a slider-rail structure. For example, the first support plate 4011 and the second support plate 4012 are each provided with a slider, and the rotation shaft 4016 is provided with a slide rail. The slider is connected to the slide rail in a slidable manner. Or, the first support plate 4011 and the second support plate 4012 are each provided with a slider, and the rotation shaft 4016 is provided with a slide groove. The slider is connected to the slide groove in a slidable manner.
When the first support plate 4011 and the second support plate 4012 are support plates, a lightening hole may be provided on each support plate to reduce the moment of inertia of the rotating support plate. The rotation shaft 4016 rotates to drive the first support plate 4011 and the second support plate 4012 to rotate, to further drive the bag holder 402 on the first support plate 4011 and the second support plate 4012 to rotate, such that the position of the multiple bag holders 402 can be switched between the bag loading station and the material filling position. The multiple bag holders 402 can keep the opening of the packaging bag open. In an embodiment, when the first support plate 4011 and the second support plate 4012 are both support plates, each bag holder 402 includes a first moving plate, a second moving plate, and a linear motor that are arranged on the support plate. The first moving plate and the second moving plate are arranged on the support plate in a slidable manner, and the linear motor drives the first moving plate and the second moving plate to move close to or away from each other.
When each bag holder 402 rotates to the bag loading station along with the support plate, the linear motor drives the first moving plate and the second moving plate to move close to each other, such that the first moving plate and the second moving plate can be easily inserted into the packaging bag. At the bag loading station, the bag loading apparatus 300 opens the opening of the packaging bag and loads the packaging bag onto the first moving plate and the second moving plate, such that the first moving plate and the second moving plate are at least partially located inside the packaging bag. Then the linear motor drives the first moving plate and the second moving plate to move away from each other and contact the packaging bag, such that the first moving plate and the second moving plate can keep the opening of the packaging bag open.
Alternatively, the first moving plate and the second moving plate are hingedly connected to the support plate. An air cylinder is provided on the support plate, and the air cylinder drives the first moving plate and the second moving plate to rotate close to or away from each other at the same time, thereby achieving the above functions.
To reduce the moment of inertia of the bag receiving apparatus, the radius of rotation of the bag receiving apparatus may be reduced while the mass is constant. In an embodiment, when the bag holder 402 rotates from the bag loading station to the material filling station, the driving mechanism drives the first support plate 4011 and the second support plate 4012 to synchronously slide, such that a distance between the end portion of the first support plate 4011 and the end portion of the second support plate 4012 decreases first and then increases. Half of the distance between the end portion of the first support plate 4011 and the end portion of the second support plate 4012 is regarded as the radius of rotation of the bag receiving apparatus.
In an embodiment, the driving mechanism is a crank linkage mechanism. For example, a rotatable crankshaft is provided on the rotation shaft 4016. One end of each of two connecting rods is hingedly connected to a crank of the crankshaft, and the other end of each of two connecting rods is hingedly connected to the first support plate 4011 and the second support plate 4012 respectively. Through the connecting rods, the crankshaft rotates to drive the first support plate 4011 and the second support plate 4012 to synchronously slide in a parallel manner towards or away from each other along the radial direction of the rotation shaft 4016, such that the distance between the end portion of the first support plate 4011 and the end portion of the second support plate 4012 decreases first and then increases. That is, the bag receiving apparatus is in a retracted state first and then in an expanded state. In another embodiment, the driving mechanism includes a screw and two threaded sleeves, and the two threaded sleeves have opposite threads. The screw is rotatably arranged on the rotation shaft 4016, and the two threaded sleeves are relatively arranged on the first support plate 4011 and the second support plate 4012. The screw is in a threaded connection with the two threaded sleeves. The screw rotates to drive the first support plate 4011 and the second support plate 4012 to synchronously slide in a parallel manner towards or away from each other along the radial direction of the rotation shaft 4016, such that the distance between the end portion of the first support plate 4011 and the end portion of the second support plate 4012 decreases first and then increases. The driving mechanism may be an air cylinder, a hydraulic cylinder, a linear motor or the like. The specific implement can be easily come up with by those skilled in the art, which is not described in detail herein.
In an embodiment, referring to
As shown in
In an embodiment, referring to
In an example, when the bag holder 402 switches from the bag loading station to the material filling station, the driving head 409 keeps stationary, and the rotation shaft 4016 rotates. The driving ring 408 rotates along with the rotation shaft 4016, such that the driving head 409 and the driving ring 408 rotate with respect to each other. The driving ring 408 drives the push-pull rod to move with respect to the rotation shaft 4016 along the axial direction, and further drives the first support plate 4011 and the second support plate 4012 to slide. Therefore, a distance between the bag holder 402 and the rotation shaft gradually decreases. That is, the radius of rotation of the bag receiving apparatus 400 decreases during the rotation of the rotation shaft 4016. Alternatively, at the bag loading station, the driving head 409 rotates first under the external force, to make the distance between the bag holder 402 and the rotation shaft decrease. Then the rotation shaft 4016 is driven to rotate. That is, the radius of rotation of the bag receiving apparatus 400 decreases first, and then the rotation shaft 4016 rotates. At the same time when the rotation shaft 4016 rotates, the driving head 409 is driven to synchronously rotate along a same direction, or rotate along with the rotation shaft 4016 along the same direction to some extent, such that the radius of rotation of the bag receiving apparatus 400 keeps decreased during rotation, thereby reducing the moment of inertia and preventing interference.
The first support plate 4011 and the second support plate 4012 may overlap each other or may be arranged in a staggered manner. A plane of symmetry of the first support plate 4011 and the second support plate 4012, i.e. a plane where the rotation axis of the rotation shaft is, is taken as a reference. The term “overlap” refers to that, when the bag receiving apparatus is retracted or expanded, as shown in
