Description

Technical Field

[0001] The utility model relates to a transport device, in particular to an automatic transport device suitable for PET BLOCK unloading. Background Art

[0002] To facilitate transportation, stacking, and storage, PET foam sheets are welded together in a heat sealer to form PET blocks, also known as PET blocks. The welded PET blocks rest on a roller on one side of the heat sealer. At this point, they are large and heavy, requiring at least two people to slowly push and unload them from the roller. They are then manually transported to a forklift or truck for storage. The welded PET blocks are large and heavy, making manual handling a risky and potentially damaging method. Handling can also cause scratches and other damage, impacting product quality. The primary drawback is that manual handling is time-consuming, labor-intensive, inefficient, and costly.

[0016] The preferred embodiment of the present invention is described below with reference to the accompanying drawings. It should be understood that the automated handling device for PET BLOCK unloading described herein is a preferred embodiment and is only used to illustrate and explain the present invention, and does not constitute a limitation of the present invention.

[0017] The directional terms or positional relationships such as "up", "down", "left" and "right" described in the present invention are based on the directional relationships in the drawings in the present invention specification and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the content protected by the present invention. Example

[0018] This embodiment Figure 1 、 Figure 2 The figure shows an automated handling device suitable for unloading PET blocks, comprising a pusher 2, a conveyor 3, a loading platform 4, and a motor (not shown). The pusher 2 and conveyor 3 are located on either side of the discharge direction of the block 1, with the loading platform 4 positioned at the end of the conveyor 3 in its transport direction.

[0019] A PET block, or PET material block, is formed by heating the surfaces of several PET raw sheets using the heat sealer's electrical heating plate and then sequentially welding them together. As the number of PET raw sheets welded increases, the block 1 moves along the heat sealer's discharge direction. It is equipped with a stop plate 5 at its front end and a flat plate 7 at its rear end. These two plates are components of the heat sealer and serve to secure the welded block 1 during the welding process. Below the block 1 is a roller 6 at the heat sealer's discharge, which is not driven by a motor.

[0020] A motorized push rod 21 is fixedly mounted on the pushing device 2 for pushing the material block 1 from the side. The motorized push rod 21 extends and retracts horizontally, with its retracted end facing the material block 1 and provided with a push head 22. The push head 22 is used to increase the contact area between the motorized push rod 21 and the material block 1, thereby improving the stability of the pushing process. To prevent scratches on the surface of the material block 1 during pushing, a rubber cover is provided on the push head 22 in this embodiment. The pushing device 2 should begin applying lateral force only after all the material blocks 1 have been welded, and return to its original retracted state after pushing the material blocks 1 away. Therefore, a material detection sensor 23 is fixedly mounted on the pushing device 2. The material detection sensor 23 is connected to an inductive control system, which is in communication with the motorized push rod 21. The material detection sensor 23 is located on a plane flush with the front end surface of the welded material block 1. When the welding of the material block 1 is completed, the material detection sensor 23 will be able to sense that the front end of the material block 1 enters its detection range. At this time, the sensing control system starts the electric push rod 21 to extend toward the material block 1 and then push the material block 1 to move in the downward direction. When the material block 1 leaves, the material detection sensor 23 does not detect the material block 1. At this time, the sensing control system controls the electric push rod 21 to retract to the initial position.

[0021] The conveyor 3 comprises a base, rotatably mounted with a plurality of guide rollers 31 arranged in sequence, their central axes parallel to the discharge direction. The guide rollers 31 rotate perpendicularly to the discharge direction. A conveyor belt (not shown) is positioned below the guide rollers 31. The belt's pulleys are connected to the power output of the motor. Rotation of the pulleys drives the guide rollers 31 above them, which in turn drives the material block 1 on the conveyor. Specifically, when the material block 1 is pushed by the pushing device 2, its lower side surface enters the guide rollers 31 of the conveyor 3. The rolling action of the guide rollers 31 causes the material block 1 to continue moving in the discharge direction, ultimately pushing the material block off the heat sealer.

[0022] The loading platform 4 is used to hold the material blocks 1 conveyed from the conveyor 3. The top surface of the loading platform 4 is flush with the top surface of the conveyor 3. The material blocks 1 are placed on the loading platform 4, awaiting removal by a forklift or ground bull. To facilitate the forklift's or ground bull's forklift's removal of the material blocks 1, a through slot is defined on the top surface of the loading platform 4. The slot's orientation aligns with the forklift's insertion direction. Specifically, the slot's orientation aligns with the conveyor's direction of transport, and its width is smaller than the width of the material block 1 but larger than the width of the forklift used to remove the material block 1. In actual production, the top surface of the loading platform 4 is relatively high from the ground, requiring the forklift's or ground bull's forklift's forklift to raise the height, which is inconvenient. Therefore, in this embodiment, several vertical springs 41 are provided on the bottom surface of the loading platform 4. When the material block 1 is fully placed on the loading platform 4, the springs 41 compress, causing the loading platform 4 to descend, facilitating the insertion of the forklift's forklift. When the material block 1 is transported away, the spring 41 rebounds, so that the upper surface of the loading platform 4 is flush with the upper surface of the conveying device 3 again.

[0023] When using this embodiment, the front end surface of the welded material block 1 reaches the material detection sensor 23, the material detection sensor 23 is communicated with the electric push rod 21, and the electric push rod 21 begins to extend to push the material block 1 to move in the downward direction. The material block 1 enters the conveying device 3, and the guide roller 31 on the conveying device 3 rolls driven by the motor to transport the material block 1 to the loading platform 4. A forklift is used to transport the material block 1 away, completing the unloading process of the PET BLOCK.
