DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figures 1 to 4 As shown, this embodiment aims to provide a mechanically structured handling device to reduce the technical problems of high labor intensity in manually handling printed product packages or high cost of using a palletizing robot. To this end, in order to achieve the above-mentioned purpose, the auxiliary unloading device for a printed product production baler provided in this embodiment includes a frame 1 and an electric hoist 2 arranged on the frame 1. In this embodiment, the frame 1 is a square frame, mainly for the stability of the structure. The electric hoist 2 is a common lifting and moving device that is commonly seen in factories, and it mainly relies on its own motor to achieve movement and lifting. In this way, it can fully meet the needs of handling. For this reason, the electric hoist 2 is arranged on the frame 1 to move along the direction from the baler to the pallet. Similarly, since the sizes of printed products vary, the sizes of packages are also different, so the lifting rope 21 can achieve a certain offset under the action of manpower, so that it is convenient for manual pushing to complete palletizing for small-sized packages.

[0022] Considering that the electric hoist 2 completes the lifting and carrying tasks, if a lifting ring is used for fixing, it will be troublesome to carry, and the straps need to be re-tied each time it is carried. Therefore, in order to improve efficiency, in this embodiment, a grabbing mechanism is connected to the lifting rope 21 of the electric hoist 2. The grabbing mechanism is mainly used to quickly pick up and put away the printed matter package. Therefore, in order to achieve the above purpose, the grabbing mechanism provided in this embodiment includes a grabbing frame 3 connected to the lifting rope 21. In this embodiment, the grabbing frame 3 includes a top plate and profiles arranged on both sides of the bottom of the top plate, wherein the top plate is used to realize the connection with the lifting rope 21. In this embodiment, considering the stability of the connection, the electric hoist 2 is a double-rope 21 electric hoist 2 to improve the stability during lifting and moving.

[0023] A fixing plate 31 is provided at both ends of the grabbing frame 3, a grabbing shaft 32 is provided at the bottom of the fixing plate 31, and bearing seats are provided on both sides of the fixing plate 31, so that the grabbing shaft 32 can be rotatably set at the bottom of the fixing plate 31, and the two ends of the grabbing shaft 32 are set through the bearing seats, and the passed part is covered with a connecting rod 33, and a grabbing plate 34 is provided between the connecting rods 33. The grabbing plate 34 is provided in a flat plate shape and is provided at the end of the connecting rod 33 away from the grabbing shaft 32. In this way, when the grabbing shaft 32 flips, the grabbing plate 34 can be driven to flip.

[0024] At the same time, a grabbing claw 35 is provided on the grabbing plate 34. The grabbing claw 35 is L-shaped and is arranged on the grabbing plate 34 at intervals along the axial direction of the grabbing shaft 32. In this way, when the grabbing claws 35 at both ends move relative to each other, they can extend under the printed matter package to complete the fixation of the printed matter package. In order to stably control the grabbing shaft 32, a flipping mechanism for driving the grabbing shaft 32 to flip is provided on the fixing plate 31.

[0025] To simplify control, in this embodiment, the flipping mechanism includes a drive cylinder 4 mounted on a fixed plate 31 and a connecting plate 41 at the power end of the drive cylinder 4. The end of the connecting plate 41, distal from the drive cylinder 4, is fixed to the grabbing shaft 32 and extends through the fixed plate 31. Thus, the grabbing shaft 32 can be flipped by the action of the drive cylinder 4. In this embodiment, the drive cylinder 4 is a pneumatic cylinder, although an electric cylinder could also be used. However, since the structure provided in this embodiment requires an air source, a pneumatic cylinder is preferred.

[0026] Considering that printed materials are paper products and are often packaged in paper, the thickness of the gripping claw 35 should preferably be relatively thin. To avoid damaging the packaging, in this embodiment, a gripping cylinder 36 is provided on the gripping frame 3. The power end of the gripping cylinder 36 is downwardly directed. A suction plate 37 is connected to the power end of the gripping cylinder 36. The suction plate 37 is disposed on the inner side of the fixed plate 31, that is, the gripping cylinder 36 is disposed between the two fixed plates 31. A negative pressure suction cup 5 is disposed on the suction plate 37. In this way, when in use, the printed material package is first adsorbed using the negative pressure suction cup 5, and then the gripping cylinder 36 is used to lift it to a certain height before the gripping claw 35 is used to secure it. This avoids the possibility of damage. In this embodiment, the main reason for not using the negative pressure suction cup 5 to complete the entire adsorption process is that only lifting to a certain height does not require the air pump to work for a long time, and the gripping claw 35 is also a one-time action, which can save costs.

[0027] To facilitate suction, in this embodiment, a suction main plate 38 is provided on the gripping frame 3, on which auxiliary negative pressure suction cups 6 are provided, and gripping cylinders are provided on both sides of the suction plate 37. Thus, the arrangement of the suction main plate 38 ensures that the gripping claws 35 maintain stability on the printed product package during the flipping process.

[0028] Through the above arrangement, the transportation of printed matter packages is effectively realized. At the same time, the entire device has a simple structure, low manufacturing cost and low use cost, and is suitable for large-scale promotion and use.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
