Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a fast-switching conveying device. Background Art

[0002] As one of the equipments with high technical content in the post-packaging, the sleeve labeling machine has been fully recognized by customers for its excellent high-speed and stable performance, unique flexible design, and safe mode of human-machine cooperation. Its application areas include food, beverage and pharmaceutical industries, condiments, juice, injection needles, milk, refined oil, etc.

[0003] After the product labeling is completed, it needs to be packaged. After packaging, it is transported to the rear end by a conveyor belt and palletized by a palletizer. Among them, in order to improve the palletizing efficiency, generally, two conveyor belts are used at the rear end to transport the products to two palletizing stations respectively. Among them, the conveyor belt at the packaging position is one, and then the products on this conveyor belt are sent to the two conveyor belts at the rear end by dividing the materials or other methods. If the conveyor belt at the rear end adopts a double-layer conveyor belt structure, that is, the structure of the upper conveyor belt and the lower conveyor belt, in the conventional method, a cylinder or an oil cylinder is set at the end of the front conveyor belt, and the height of the conveyor belt end is adjusted by pushing the height of the conveyor belt end. However, in this method, since the height of the conveyor belt end at the front end is different, and the relative position of the head of the conveyor belt at the front end is fixed, the height of the conveyor belt end is different, and there will be a certain distance between the upper or lower conveyor belt corresponding to the rear end, and there will inevitably be a larger distance between one group of the upper or lower conveyor belts and the end of the front conveyor belt. In this way, when the front conveyor belt delivers the product conveyor belt to the rear conveyor belt, the gap is too large, and the end of the product after packaging may fall into the gap and become stuck. In this way, it is necessary to set a cylinder or oil cylinder at the head of the rear conveyor belt to adjust the height of the rear conveyor belt, so that the gap between the end of the front conveyor belt and the upper layer or lower layer of the rear conveyor belt is as small as possible, so as to prevent the material from getting stuck or falling. In this structure, a cylinder or oil cylinder is required at both ends of the conveyor belt on each side, and the entire conveyor belt requires at least 4 cylinders or oil cylinders, which is relatively expensive. The four cylinders or oil cylinders need to work and travel synchronously, and the debugging difficulty is also relatively large. Summary of the invention

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figures 1 to 3 As shown, a fast-switching conveying device comprises a left conveying assembly 1 and a right conveying assembly 2, wherein the left conveying assembly 1 comprises an upper conveying assembly 3 and a lower conveying assembly 4 spaced apart from each other;

[0030] A connecting component 5 and a driving mechanism 6 for driving the connecting component 5 to reciprocate are also provided, and the connecting component 5 is arranged directly below the left conveying component 1 and the right conveying component 2;

[0031] The left end of the connecting component 5 is rotatably connected to the front and rear sides of the right end of the left conveying component 1, and the right end of the connecting component 5 is rotatably connected to the front and rear sides of the left end of the right conveying component 2. When the driving mechanism 6 drives the connecting component 5 to rotate reciprocatingly, the connecting component 5 drives the right conveying component 2 and the left conveying component 1 to rotate, and makes the right conveying component 2 face the upper conveying component 3 or face the lower conveying component 4.

[0032] In this embodiment, the right conveying assembly and the tops of the upper conveying assembly and the lower conveying assembly are all conveyed from right to left, and the product is conveyed from the top of the right conveying assembly to the left. In one state, the left top of the right conveying assembly is directly opposite to the right top of the upper conveying assembly, and the product will be conveyed from the right conveying assembly to the top of the upper conveying assembly to the left, and the product will be sent away through the upper conveying assembly. When switching is required, the driving mechanism drives the connecting component to rotate, so that the left top of the right conveying assembly is directly opposite to the right top of the lower conveying assembly, and the product will be conveyed from the right conveying assembly to the top of the lower conveying assembly to the left, and the product will be sent away through the lower conveying assembly. By driving the reciprocating rotation of the connecting component driven by the driving mechanism, the right conveying assembly can be directly opposite to the upper conveying assembly or the lower conveying assembly, and the switching between the two can be realized.

[0033] See also Figure 1 , 2 As shown, the connecting component 5 includes a connecting shaft 7 and connecting pieces respectively arranged at the front and rear ends of the connecting shaft. The driving mechanism 6 is configured to drive the connecting shaft 7 to rotate, and the connecting pieces at both ends are respectively rotatably connected to the right end of the left conveying component 1 and the left end of the right conveying component 2.

[0034] The connecting member includes a connecting plate 8, a left connecting rod 9 and a right connecting rod 10, the middle part of the connecting plate 8 is connected to the end of the connecting shaft 7, the bottom of the left connecting rod 9 is rotatably connected to the connecting plate 8 on the left side of the connecting shaft 7, and the top of the left connecting rod 9 is rotatably connected to the right end of the left conveying assembly 1;

[0035] The bottom of the right connecting rod 10 is rotatably connected to the connecting plate 8 on the right side of the connecting shaft 7 , and the top of the right connecting rod 10 is rotatably connected to the left end of the right conveying assembly 2 .

[0036] When the connecting shaft 7 drives the connecting plate 8 to rotate counterclockwise to the first position, the connecting plate 8 is tilted upward from left to right, and at this time, the right connecting rod 10 pushes the top left side of the right conveying assembly 2 to move upward, and the left connecting rod 9 pulls the right end of the left conveying assembly 1 to move downward, so that the top left side of the right conveying assembly 2 is arranged opposite to the top right side of the upper conveying assembly 3;

[0037] When the connecting shaft 7 drives the connecting plate 8 to rotate clockwise to the second position, the connecting plate 8 is tilted downward from left to right. At this time, the right connecting rod 10 pulls the top left side of the right conveying component 2 to move downward, and the left connecting rod 9 pushes the right end of the left conveying component 1 to move upward, so that the top left side of the right conveying component 2 is set opposite to the top right side of the lower conveying component 4.

[0038] The driving mechanism drives the connecting shaft to rotate clockwise and counterclockwise, and drives the connecting plate to rotate to the first position or the second position, so that the connecting plate switches between the first position and the second position, so that the right conveying component faces the upper conveying component or the lower conveying component, and the feeding is quickly switched.

[0039] See also Figure 1 , 2 As shown, the distance between the bottom of the left connecting rod 9 and the connecting shaft 7 is smaller than the distance between the bottom of the right connecting rod 10 and the connecting shaft 7. In this way, when the connecting plate rotates, the lifting height of the top of the right connecting rod will be greater than the lifting height of the top of the left connecting rod, so that the top left end of the right conveying assembly can quickly face the upper conveying assembly or the lower conveying assembly to achieve rapid switching.

[0040] See also Figure 1 , 2 As shown, a frame 11 is also provided, and the left conveying assembly 1, the right conveying assembly 2, the connecting component 5 and the driving mechanism 6 are installed on the frame 11, and the left ends of the upper conveying assembly 3 and the lower conveying assembly 4 are respectively rotatably connected with the frame 11, and the front and rear sides of the right end of the upper conveying assembly 3 are respectively rotatably connected with the front and rear sides of the right end of the lower conveying assembly 4 through a connecting rod 12; the left end sides of the connecting component 5 are respectively rotatably connected with the front and rear sides of the right end of the lower conveying assembly 4; the right ends of the upper conveying assembly and the lower conveying assembly are positioned by the connecting rod, so that there is a stable spacing between the upper and lower conveying assemblies, and the lower conveying assembly can convey the products, and at the same time, the two left connecting rods are respectively rotatably connected with the front and rear sides of the lower conveying assembly, so that when the right end of the lower conveying assembly is pushed up and down, the right end of the upper conveying assembly can be driven to rise and fall synchronously through the connecting rod.

[0041] The right end of the right conveying assembly 2 is rotatably connected to the frame 11, and the two sides of the right end of the connecting component 5 are rotatably connected to the front side and the rear side of the left end of the right conveying assembly 2. The tops of the two right connecting rods are rotatably connected to the front side and the rear side of the left end of the right conveying assembly, respectively. The change of the position of the right connecting rod drives the change of the position of the left end of the right conveying assembly, and the change of the position of the left connecting rod drives the change of the position of the right end of the left conveying assembly.

[0042] Furthermore, conveyor belts 13 are respectively arranged around the upper conveying assembly 3, the lower conveying assembly 4 and the right conveying assembly 2; and the products are conveyed by the conveyor belts.

[0043] When the driving mechanism drives the connecting component to rotate to the first position, the left end of the right conveying assembly is arranged close to the right end of the upper conveying assembly, and the left side of the top of the conveying belt of the right conveying assembly is arranged opposite to the right side of the top of the conveying belt of the upper conveying assembly;

[0044] When the driving mechanism drives the connecting component to rotate to the second position, the left end of the right conveying component is arranged close to the right end of the lower conveying component, and the left side of the top of the conveyor belt of the right conveying component is arranged opposite to the right side of the top of the conveyor belt of the lower conveying component.

[0045] By arranging conveyor belts on the right conveying assembly, the upper conveying assembly and the lower conveying assembly, the top of the corresponding conveyor belts is conveyed from right to left, so that the product can be conveyed from the right conveying assembly to the upper conveying assembly and the lower conveying assembly to the left, and the corresponding upper conveying assembly and the lower conveying assembly are used to convey the product to the corresponding position, thereby realizing fast material separation.

[0046] In the present invention, the drive mechanism has two structures. The first structure is that the drive mechanism 6 is a motor assembly, and the output shaft of the motor assembly is connected to one end of the connecting member. Preferably, the motor assembly is mounted on the frame, and the motor assembly is connected to one end of the connecting shaft, so as to realize the clockwise and counterclockwise rotation of the connecting shaft and realize the switching of the connecting plate to the first position or the second position. The motor assembly is a single motor, or the motor assembly is a combination of a motor and a reducer, see Figure 1 , 2 shown.

[0047] The second type: the driving mechanism 6 includes two driving cylinders 14, and the two driving cylinders 14 are symmetrically arranged on both sides of the connecting component. The bottom of the driving cylinder is rotatably connected to the frame, and the output shaft at the top of the driving cylinder is rotatably connected to the corresponding side of the connecting component. Among them, protrusions 15 are respectively arranged on both sides of the middle of the connecting shaft, and the output shaft of each driving cylinder is rotatably connected to the protrusion on the corresponding side, and the bottom of the driving cylinder is rotatably connected to the frame. When it is necessary to push the connecting shaft to rotate clockwise, the output shaft of the driving cylinder on the left side of the connecting shaft extends, and the output shaft of the driving cylinder on the right side of the connecting shaft retracts, driving the connecting shaft to rotate clockwise, so that the connecting plate rotates to the second position. When it is necessary to push the connecting shaft to rotate counterclockwise, the output shaft of the driving cylinder on the left side of the connecting shaft retracts, and the output shaft of the driving cylinder on the right side of the connecting shaft extends, driving the connecting shaft to rotate counterclockwise, so that the connecting shaft rotates to the first position. The dual driving cylinder structure has a greater driving force and is more stable. See. Figure 3 shown.

[0048] In the utility model, the driving mechanism only needs to use one motor assembly or two driving cylinders, which is more cost-effective and more convenient and stable to debug.
