Detailed Description

Referring to fig. 1 to 3 and 8, a lifting and conveying device a of the labeling machine of the present invention is used for conveying a plurality of containers 91, and the lifting and conveying device a includes a conveyor 10 and a lifting mechanism 20; in the present embodiment, the apparatus further includes a pressing mechanism 30, at least one label positioning assembly 40, and a mode switching mechanism 50.

The conveyor 10 preferably includes a frame 11 and a conveyor belt 12, the conveyor belt 12 being movably disposed around the frame 11 and capable of conveying a plurality of containers 91 along a conveying direction D. The conveyor belt 12 is preferably formed by sequentially fixing a plurality of plate bodies 121 on two mutually parallel endless chains 122 (only a part of the conveyor belt 12 is schematically illustrated in the figure), but the structure of the conveyor belt 12 is not limited thereto, and may be an endless belt, for example.

The lifting mechanism 20 is disposed below the conveying belt 12 of the conveyor 10, and the lifting mechanism 20 includes a guide 21 and a plurality of lifting elements 22.

The guide 21 is formed with a lifting surface 211 and preferably also a holding surface 212, the guide 21 preferably being an elongated plate. The lifting surface 211 is elongated and extends in the conveying direction D of the conveyor belt 12. Two opposite ends of the lifting surface 211 along the conveying direction D are respectively a first end 2111 and a second end, and the second end is located in the direction of the first end 2111 along the conveying direction D. The height of the lifting surface 211 increases from the first end 2111 toward the second end, that is, the height of the lifting surface 211 increases along the conveying direction D. The lifting surface 211 is specifically a slope, but in other embodiments, the lifting surface 211 may be a curved surface. One end of the maintaining surface 212 is connected to the second end of the lifting surface 211, and the other end of the maintaining surface 212 extends horizontally in the conveying direction D of the conveyor belt 12.

The lifting components 22 are arranged at intervals on the inner side of the conveying belt 12, and the position of each lifting component 22 corresponds to one container 91; specifically, the conveyor belt 12 is spaced apart by a plurality of lifting assemblies 22, and each container 91 to be processed is positioned directly above one of the lifting assemblies 22 by means other than the present invention.

Referring to fig. 3-6, each lifting assembly 22 has a lifting member 221, and preferably also has a housing 222, a return spring 223, and a roller 224. The raising member 221 is slidable upward to protrude from the conveyor belt 12, and is slidable downward to retract into the conveyor belt 12. The raising member 221 is preferably a rod extending up and down, and at least one rotation-preventing portion 2211 is formed on the rod in a protruding manner. The housing 222 is fixed on a plate 121 of the conveyor belt 12 and is sleeved outside the lifting member 221. The housing 222 has at least one anti-rotation hole 2221 formed therein, and the anti-rotation hole 2221 extends up and down. The rotation-preventing portion 2211 of the lifting member 221 slidably penetrates through the corresponding at least one rotation-preventing hole 2221 of the housing 222, so as to prevent the lifting member 221 from rotating around itself.

The elastic restoring member 223 drives the corresponding raising member 221 to move downward, so that when the raising member 221 moves above the guide member 21, the bottom end of the raising member 221 can keep contact with the lifting surface 211 or the maintaining surface 212 of the guide member 21, thereby ensuring that the raising member 221 is always located at a predictable set position.

The rollers 224 are rotatably disposed at the bottom end of the corresponding top member 221, so that the top member 221 contacts the guide member 21 with the rollers. The cooperation between the roller 224 and the anti-rotation holes 2221 and the anti-rotation portions 2211 can keep the rolling direction of the roller 224 aligned with the conveying direction D, which has the effect of reducing the friction resistance between the lifting member 221 and the guide member 21.

The lifting mechanism 20 cooperates with the conveyor 10 as follows:

referring to fig. 8, each lifting assembly 22 moves in the conveying direction D along with the operation of the conveyor belt 12, and when the lifting assembly 22 is moved by the conveyor belt 12 to a position corresponding to the lifting surface 211 of the guide member 21, the bottom end of the lifting member 221 first contacts the first end 2111 of the lifting surface 211. As the lifting elements 22 continue to move in the conveying direction D (i.e., the second end of the lifting surface 211), the lifting members 221 are gradually moved upward and protrude from the conveyor belt 12 by being supported by the lifting surface 211 with gradually increasing height. In the embodiment, the position of the lifting assembly 22 corresponds to the lifting surface 211 of the guide 21, i.e., the lifting assembly 22 is located directly above the lifting surface 211, but not limited thereto, the lifting assembly 22 may be deviated from the position directly above the lifting surface 211, and only the lifting member 221 can contact the lifting surface 211.

When the lifting member 221 is pushed by the lifting surface 211 to protrude from the conveying belt 12, the top end of the lifting member 221 will lift the container 91 directly above, so as to form a gap between the bottom periphery of the container 91 and the conveying belt 12, and the gap will allow the label 92 sleeved outside the container 91 to move further downward, so as to prepare for the subsequent bottom heat-shrinking operation.

After the lifting member 221 is separated from the lifting surface 211 along with the operation of the conveyor belt 12, the bottom end of the lifting member 221 will continuously abut against the maintaining surface 212 of the guide member 21 to keep the container 91 at the lifted position, and the oven can perform the heat shrinking process on the label 92 at this time, so that the label 92 can wrap the bottom periphery of the container 91 after the heat shrinking process.

In the present embodiment, the lifting member 221 tends to move downward due to the pushing of the elastic restoring member 223, so the guide member 21 needs to form the maintaining surface 212 to maintain the height of the lifting member 221. In other embodiments, the return elastic member 223 may be omitted, and the resistance of the lifting member 221 to slide up and down is increased to enable the lifting member 221 to stay at any height position, so that the guide member 21 does not need to form the maintaining surface 212 to maintain the height position of the container 91.

Referring to fig. 2 and fig. 7, the pressing mechanism 30 is located above the conveyor 10 and includes a main body 31, a driving member 32 and a plurality of pressing members 33. Above the conveyor 10 is a body 31, which is elongated and extends in the conveying direction D. The driver 32 is annular and is disposed around the main body 31 in a movable manner, and specifically, the driver 32 is a chain. The pressing members 33 are provided at intervals on the driver 32, and can abut downward against the container 91. The holddowns 33 are spaced apart the same distance as the raised members 221 of the lift assembly 22. When the lifting member 221 protrudes upward from the conveyor 12, the pressing member 33 and the lifting member 221 clamp and fix the container 91 from opposite directions, thereby preventing the lifted container 91 from falling down.

Referring to fig. 1, 8, 10 and 11, the position of the at least one label setting assembly 40 corresponds to the position of the maintaining surface 212 of the guide 21, specifically, overlaps the position of the maintaining surface 212 in the conveying direction D. Each label positioning assembly 40 includes a connector 41, a flexible turntable 42, and a motor 43. The connecting base 41 is disposed at one side of the conveyor 10, the flexible rotary disk 42 is rotatably disposed on the connecting base 41, and the flexible rotary disk 42 is preferably inclined to contact the label 92 outside the container 91. The motor 43 rotates the flexible carousel 42 and causes the flexible carousel 42 to move the labels 92 of the containers 91 down against the conveyor belt 12.

Referring to fig. 3, 8 and 9, the mode switching mechanism 50 has an actuator 51 and a transmission assembly 52. The transmission assembly 52 connects the actuator 51 and the guide 21 of the lifting mechanism 20 so that the actuator 51 can control the position of the guide 21. The actuator 51 is preferably a cylinder and the transmission assembly 52 is preferably a linkage.

The mode switching mechanism 50 has a normal state (as shown in fig. 8) and a disengaged state (as shown in fig. 9); in the disengaged state, the actuator 51 moves the guide member 21 downward through the transmission assembly 52 to keep the lifting surface 211 of the guide member 21 separated from the lifting member 221 of the lifting assembly 22, and the lifting and conveying device a does not lift the container 91, so that the container 91 is suitable for producing a container 91 without bottom wrapping. In a normal state, the lifting surface 211 of the guide member 21 can abut against the lifting member 221.

Referring to fig. 7, 12 and 13, the lifting conveyor a is preferably combined with a labeling device B and an oven C to form a label set, wherein most of the lifting conveyor a penetrates through the oven C. The label sleeving machine firstly uses a label sleeving device B to unfold the flattened strip-shaped label 92 into a cylinder shape, cuts the cylinder shape into a proper length and then sleeves the label outside the container 91 one by one. Then, the container 91 is transported to the lifting and transporting device a, where the container 91 is lifted and the label 92 is moved down to a proper position, and then the label 92 is fixed outside the container 91 by heat shrinking by the oven C, so as to complete all processes of the label maker set.

To sum up, the utility model discloses only need set up the guide 21 that a shape is simple and a plurality of top height piece 221 that can slide from top to bottom on conveyer 10, can borrow by the power of conveyer 10 itself to reach the efficiency of lifting container 91. Compare the conveyor that lifts that the structure is complicated among the prior art, the utility model discloses a part is small in quantity and simple structure, has reduce cost and the easy efficiency of maintaining.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, it is not intended to limit the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiment of the above embodiments without departing from the scope of the present invention.
