Description

Technical Field

[0001] This utility model belongs to the field of product packaging, and in particular relates to a gable box packaging material conveying and packing device. Background Technology

[0002] When packaging beverages such as milk, gable-top boxes are sometimes used to facilitate consumers' pouring and sharing. These boxes usually have a large capacity, and if they are suddenly subjected to external force during the conveyor packing process, they are prone to tipping over. If guardrails are installed on the conveyor belt to apply lateral force for guidance, the large mass of the packaging itself, combined with prolonged and rapid friction with the guardrails, can easily cause wear and damage to the printed patterns on the side of the packaging or even the packaging itself, affecting product quality. Utility Model Content

[0003] In view of this, the present invention aims to provide a gable box packaging material conveying and boxing device to pack gable boxes while reducing the damage to the gable box packaging caused by the conveying device.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A gable box packaging material conveying and packing device, comprising:

[0006] The feeding conveyor belt and the sorting conveyor belt are provided, with the feeding conveyor belt located on one side of the sorting conveyor belt. A blocking bar is provided above the sorting conveyor belt. The blocking bar can approach or move away from the sorting conveyor belt. When the blocking bar is at its extreme position close to the sorting conveyor belt, the roof box can abut against the blocking bar.

[0007] The pusher unit includes two movable plates arranged opposite each other, and the two movable plates can move along the width direction of the feeding conveyor belt, thereby pushing the roof box on the feeding conveyor belt to move towards the feeding conveyor belt and so that the roof box can abut against the blocking bar. The two movable plates can move synchronously when moving along the feeding conveyor belt towards the feeding conveyor belt.

[0008] The container conveyor has a gripping unit on top that can move between itself and the material handling conveyor belt.

[0009] Furthermore, a temporary support strip is provided between the feeding conveyor belt and the sorting conveyor belt, and the upper surface of the temporary support strip is in the same plane as the upper surfaces of the feeding conveyor belt and the sorting conveyor belt.

[0010] Furthermore, the feeding conveyor belt includes a conveying area and a sorting area. The sorting area is located on one side of the feeding conveyor belt. A limiting cylinder is also provided above the sorting area. Two clamping plates are arranged opposite each other on the side of the conveying area. When the piston rod of the limiting cylinder extends, the two clamping plates are in a relaxed state. When the piston rod of the limiting cylinder retracts, the two clamping plates are in a clamped state.

[0011] Furthermore, when the limiting cylinder is in the retracted state, the blocking rod and the piston rod end of the limiting cylinder are in the same plane.

[0012] Furthermore, this packing device also includes a material distribution conveyor belt, which is in the same straight line as the material handling conveyor belt, and the roof box can move onto the material distribution conveyor belt when the blocking bar moves away from the material handling conveyor belt.

[0013] Furthermore, a transition strip is provided between the material distribution conveyor belt and the material handling conveyor belt, and the upper surface of the transition strip is in the same plane as the upper surfaces of the material distribution conveyor belt and the material handling conveyor belt.

[0014] Furthermore, the material distribution conveyor belt is provided with a material distribution push rod, and the material distribution push rod can move along the length direction of the material distribution conveyor belt.

[0015] Furthermore, the speed of the material distribution conveyor belt is greater than or equal to the speed of the material handling conveyor belt.

[0016] Furthermore, the box conveying device includes a box conveyor belt, on which a box-supporting mechanism is provided that can approach or move away from the box conveyor belt. The box-supporting mechanism includes a fixed frame and multiple flexible plates, and the flexible plates are placed inside the fixed frame. One side edge of the flexible plate is fixedly connected to the fixed frame, and the other side extends downward at an angle so that the flexible plate surrounds and forms a funnel shape.

[0017] Furthermore, the conveyor belt of the box is provided with a second stopper and a first stopper along the direction of movement, and the distance between the first stopper and the second stopper is greater than the space occupied by the box.

[0018] Compared with existing technologies, the gable box packaging material conveying and packing device of this utility model has the following advantages:

[0019] This utility model uses two opposing movable plates to clamp and limit the roof box to be moved from both sides, preventing the roof box from tipping over during lateral movement. At the same time, through multiple movements of the movable plates, the roof boxes on the feeding conveyor belt are moved and arranged in batches onto the sorting conveyor belt for easy transport and packing.

[0020] Temporary support bars are used to avoid affecting the movement of the conveyor belt due to insufficient support at the edges of the conveyor belt during the pushing of the roof box;

[0021] By using the speed difference between the material handling conveyor belt and the material distribution conveyor belt, a gap is created between the roof boxes on the material distribution conveyor belt and the roof boxes on the material handling conveyor belt, so as to avoid the grabbing and lifting process from affecting the subsequent roof boxes.

[0031] The roof box packaging material conveying and packing device of this utility model includes:

[0032] The present invention describes a feeding conveyor belt 1 and a sorting conveyor belt 2. The feeding conveyor belt 1 includes a conveying area 11 and a sorting area 12 along its length, and the sorting area 12 is located on one side of the sorting conveyor belt 2. The sorting conveyor belt 2 and the feeding conveyor belt 1 move in the same direction. A pushing unit 3 is straddling the feeding conveyor belt 1 and the sorting conveyor belt 2. The pushing unit 3 includes two opposing movable plates 31, which can move along the width of the sorting conveyor belt 2. The material to be conveyed is placed between the two movable plates 31. Specifically, one movable plate 31 moves on the sorting conveyor belt 2, and the other movable plate 31 moves above the feeding conveyor belt 1. When the first batch of predetermined quantity of material is conveyed to the sorting area 12 along the feeding conveyor belt 1, the first batch of gable boxes is placed between the two movable plates 31. In the next step, the two moving plates 31 move synchronously, causing the first batch of roof boxes to move onto the material handling conveyor belt 2 through the limiting movement of the two moving plates 31. Then, the moving plate 31 closer to the feeding conveyor belt 1 moves away from the other moving plate 31 to its limit position, and the feeding conveyor belt 1 transports the second batch of roof boxes between the two moving plates 31. Then, the two moving plates 31 move synchronously towards the material handling conveyor belt 2 again. This process is repeated so that a predetermined number of batches of roof boxes move onto the material handling conveyor belt 2 and are neatly arranged, waiting to be transported to the next station by the material handling conveyor belt 2. During this process, a blocking bar 21 is provided above the material handling conveyor belt 2. The blocking bar 21 is controlled by the piston rod of a cylinder, so that it can move closer to or away from the material handling conveyor belt 2. When the blocking bar 21 is at its limit position close to the material handling conveyor belt 2, the roof boxes on the material handling conveyor belt 2 can abut against the blocking bar 21, thereby keeping the roof boxes pushed onto the material handling conveyor belt 2 stationary.

[0033] A temporary support strip 22 is provided between the feeding conveyor belt 1 and the sorting conveyor belt 2. The upper surface of the temporary support strip 22 is in the same plane as the upper surface of the feeding conveyor belt 1 and the sorting conveyor belt 2. During the process of the moving plate 31 pushing the roof box to the sorting conveyor belt 2, the roof box is supported by the temporary support strip 22 to avoid the roof box bottom being unstable due to the low edge rigidity of the two support belts, which could cause jamming or tipping during the movement.

[0034] A limiting cylinder 4 is also provided above the material distribution area 12. More specifically, the limiting cylinder 4 is located at the end of the material distribution area 12, and a limiting plate 41 is provided at the end of the piston rod of the limiting cylinder 4. In the initial stage, the piston rod of the limiting cylinder 4 extends, and the roof box on the feeding conveyor belt 1 can be tightly pressed against the limiting plate 41. When the number of roof boxes in the material distribution area 12 reaches a predetermined number, the piston rod of the limiting cylinder 4 retracts, thereby increasing the gap between the roof boxes in the material distribution area 12 and the roof boxes in the feeding area, so that the moving plate 31 can push the roof boxes in the material distribution area 12, while avoiding affecting the subsequent roof boxes. In this embodiment, more specifically, two clamping plates (not shown in the figure) are arranged opposite each other on the side of the conveying area 11. When the piston rod of the limiting cylinder 4 extends, the two clamping plates are in a relaxed state. When the piston rod of the limiting cylinder 4 retracts, the two clamping plates are in a clamped state. This prevents subsequent roof boxes from continuing to enter the distribution area 12, thereby further preventing the roof boxes in the feeding area from affecting the pushing of roof boxes in the distribution area 12. Specifically, the clamping plate can be part of the guardrails on both sides of the feeding conveyor belt 1. This part of the guardrail is placed on both sides of the conveying area 11, and at least one side of the guardrail is fixed to the piston rod of a cylinder. The distance between the two guardrails is controlled by the cylinder, thereby clamping the roof boxes in the conveying area 11 through the guardrails. Alternatively, a cylinder-controlled push plate can also be provided at the end of the conveying area 11. The push plate cooperates with the guardrail of the conveying area 11 to clamp the roof boxes at the end of the conveying area 11, thereby preventing subsequent materials from continuing to move forward.

[0035] In order to facilitate the smooth pushing of a batch of roof boxes onto the material conveyor belt 2 by the moving plate 31, in this embodiment, the end of the blocking rod 21 is positioned above the temporary support bar 22, and when the piston rod of the limiting cylinder 4 is in the retracted state, the end of its piston rod is in the same plane as the blocking bar, so that the roof box closest to the blocking bar contacts the blocking rod 21 while separating from the limiting cylinder 4.

[0036] In this embodiment, the movable plate 31 can be connected to the synchronous belt via a hanger, and the movement of the movable plate 31 can be controlled by two sets of synchronous belts. Those skilled in the art can also control the movement of the movable plate 31 by using a stepper motor to drive a lead screw or other mechanism.

[0037] The feeding conveyor belt 1 and the sorting conveyor belt 2 of this utility model also include a sorting conveyor belt 5. The sorting conveyor belt 5 and the sorting conveyor belt 2 are in the same straight line, and when the blocking bar 21 moves away from the sorting conveyor belt 2, the gable box can move towards the sorting conveyor belt 5. The sorting conveyor belt 5 and the sorting conveyor belt 2 are controlled by stepper motors. In this embodiment, whenever the blocking bar 21 is raised, the gable box on the sorting conveyor belt 2 can be filled with multiple boxes. The sorting conveyor belt 2 moves in stages. Specifically, when the sorting conveyor belt 2 moves, its speed is the same as that of the sorting conveyor belt 5. After the material that can fill a box is transported to the sorting conveyor belt 5, the sorting conveyor belt 2 stops working, so that a gap is formed between the material behind and the material in front. This avoids the friction or shaking generated during the lifting of the gable box during the box grabbing and packing process, which could affect the gable box behind and cause it to tip over. The material distribution conveyor belt 5 is also equipped with a material distribution push rod 51, which can move along the length of the material distribution conveyor belt 5. The material distribution push rod 51 is driven by a material distribution electric cylinder, and the screws of the other material distribution electric cylinders are fixedly connected. The material distribution push rod 51 can move to the material sorting conveyor belt 2 and cooperate with the material sorting conveyor belt 2 to make the material move to the material distribution conveyor belt 5. After each package of material is packed, the material distribution electric cylinder controls the material distribution push rod 51 to move in front of the next group of pre-packed materials and moves with the material sorting conveyor belt 2 and the material distribution conveyor belt 5 until the group of pre-packed materials stops. The material distribution push rod 51 applies a pushing force to the material during the stopping process to prevent the material from tilting forward under the action of inertia during the stopping process of the conveyor belt. A transition strip 52 is provided between the material distribution conveyor belt 5 and the material handling conveyor belt 2. The upper surface of the transition strip 52 and the upper surface of the material distribution conveyor belt 5 and the material handling conveyor belt 2 are in the same plane, so that the material on the material handling conveyor belt 2 can be smoothly transferred to the material distribution conveyor belt 5.

[0038] The feeding conveyor belt 1 and the sorting conveyor belt 2 of this utility model also include a box conveying device, which has a gripping unit 6 above it that can move between itself and the sorting conveyor belt 2. The box conveying device includes a box conveyor belt 7, on which a box-supporting mechanism 73 that can move closer to or further away from the box conveyor belt 7 is provided. The box-supporting mechanism 73 includes a fixed frame 731 and a plurality of flexible plates 732, and the flexible plates 732 are placed inside the fixed frame 731. One edge of the flexible plate 732 is fixed to the fixed frame 731, and the other side is inclined towards... The downward extension causes the flexible plate 732 to surround and form a funnel shape. The fixed frame 731 is controlled by a vertically arranged electric cylinder, causing the box-supporting mechanism 73 to move vertically. When the packaging box moves directly below the box-supporting mechanism 73, the electric cylinder controls the box-supporting mechanism 73 to move downward, so that the closed end of the funnel extends into the packaging box. When the gripping unit 6 grips the gable box and passes it through the funnel from above the box-supporting mechanism 73 into the packaging box, the flexible plate 732 on the side of the box-supporting mechanism 73 opens outward to facilitate the insertion of the gable box into the packaging box. Afterward, the electric cylinder controls the box-supporting mechanism 73 to move upward, waiting for the next packaging box to enter the workstation. In this embodiment, the box conveyor belt 7 is provided with a second stopper 72 and a first stopper 71 along the direction of movement, and the distance between the first stopper 71 and the second stopper 72 is greater than the space occupied by the box. During operation, the first stopper 71 includes two opposing baffles, and cylinders are respectively provided on both sides of the box conveyor belt 7, with the baffles fixedly connected to the piston rods of the cylinders; the second stopper 72 includes two opposing clamping plates, and cylinders controlling the movement of the clamping plates are also respectively provided on both sides of the box conveyor belt 7, with the baffles fixedly connected to the piston rods of the cylinders; the second stopper 72 includes two opposing clamping plates. When the packaging box moves to the position of the first stopper 71, the baffles extend and block the packaging box. At this time, the packaging box is placed directly below the box-supporting mechanism 73, waiting for the material to be packed. After the packing is completed, the second stopper 72 clamps the second packaging box, and then the first stopper 71 releases the packed packaging box, creating a gap between the first and second packaging boxes. After the first packaging box has completely passed the first stopper 71, the baffles extend and block the second packaging box, waiting for the packing work to begin.

[0039] In this embodiment, the gripping unit 6 uses a matrix of pneumatic grippers to clamp the edge portion of the top of the roof box, thereby picking up the roof box. It is connected to a truss robot, and optionally, it can also be connected to a robotic arm or a triple robot to control its own movement and operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
