Description

Technical Field

[0001] The invention relates to a loading method of a container pallet loader, belonging to logistics loading equipment. Background Art

[0002] Currently, palletizing and loading containers onto trucks is still done by forklifts. When the interior of the container is at the same level as the warehouse floor, a forklift is driven into the container to load the truck. When the warehouse floor is at the same level as the road, a road forklift cooperates with the forklift inside the container to place the pallets.

[0003] Both pallet stacking methods require the forklift to repeatedly turn around inside the container. Due to the limited space inside the container, this takes time for the forklift to turn around, resulting in low overall efficiency. Summary of the Invention

[0004] The present invention provides a container pallet loader and a loading method, which solve the problem of low loading efficiency of container pallet forklifts.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] The container pallet loader of the present invention includes a mobile vehicle and a pallet fork; the mobile vehicle includes a chassis, a steering seat, and a forward extension arm. The chassis is U-shaped when viewed from above, and mobile wheel groups are provided at the bottom of both sides of the U-shape. A steering seat is provided at the bottom of the U-shape. The forward extension arm is provided on the steering seat. The forward extension arm can rotate to both sides by a certain angle on the steering seat. The pallet fork is provided at the front end of the forward extension arm. The pallet fork at the front end of the forward extension arm is located at the U-shaped opening of the chassis. When the container enters the U-shaped front end space of the chassis, the forward extension arm drives the pallet fork to penetrate into the container to the deepest position. The pallet fork is a liftable pallet fork.

[0007] According to the container pallet loader, it also includes loading tracks, which are arranged in pairs in parallel. The movable wheel group is a guide wheel group. The guide wheel groups on both sides of the chassis are respectively located on the two loading tracks and move back and forth. The container drives into the space between the two loading tracks for loading operations.

[0008] According to the container pallet loader, a palletizing robot is set at the end position of the palletizing conveyor line. The palletizing robot places the bagged or boxed goods on the pallet, which is placed at the end position of the palletizing conveyor line. After palletizing, the pallet is transported to the end loading position by the palletizing conveyor line.

[0009] According to the container pallet loader, it also includes a track section conveyor line. The track section conveyor line and the stacking section conveyor line are on the same straight line. Moving wheels and corresponding conveying rails are provided at the bottom of the track section conveyor line. The track section conveyor line is perpendicular to the loading track. The track section conveyor line moves between the middle and the edge of the loading track. When the track section conveyor line moves to the edge position of the loading track, it is connected with the stacking section conveyor line. When the track section conveyor line moves to the middle position of the loading track, it is on the movement path of the pallet fork.

[0010] According to the container pallet loader, the stacking conveyor line is parallel to the loading track and is located between the two loading tracks, and the forward extension arm can rotate 360 ​​degrees around the steering seat.

[0011] According to the container pallet loader, the track section conveyor line is divided into a bottom trolley and an upper track conveyor, and the axle of the moving wheel is connected to the drive motor through a synchronous transmission mechanism.

[0012] According to the container pallet loader, a pallet shaping machine is further provided on one side of the palletizing conveyor line.

[0013] The container pallet loader loading method of the present invention comprises the following steps:

[0014] 1) The pallet is placed at the palletizing position of the palletizing conveyor, and the palletizing robot places the goods on the pallet;

[0015] 2) The palletizing conveyor drives the palletizing pallet to the end;

[0016] 3) The mobile vehicle moves and the forward extension arm on the mobile vehicle rotates to the working position of the pallet fork;

[0017] 4) The pallet fork picks up the cargo and lifts it;

[0018] 5) The mobile vehicle moves to drive the forward arm and stacking pallet into the container;

[0019] 6) The forward extension arm on the mobile vehicle rotates to the placement position, and the pallet fork lowers the stacking pallet;

[0020] 7) The mobile vehicle moves to drive the forward extension arm and pallet fork out of the container, and repeat steps 1) to 6) to load the container.

[0021] The advantages of the present invention are:

[0022] When using this device, there is no need to turn around inside the container. The forward-extending arm can enter and exit the container and place it in one go, making it more efficient than a forklift.

[0023] This device expands the range of motion of the pallet fork from outside the container to inside the container by designing the mobile vehicle structure and the forward extension arm, which is suitable for the requirements of large-scale and fast pallet container loading.

[0024] The forward extension arm of the device structure can swing, and the pallet fork can be raised and lowered, which effectively solves the problem of loading space arrangement of stacked pallets in containers, improves the placement density, and does not cause low placement density due to problems with handling equipment.

Implementation Method

[0031] The specific content of the present invention is described in detail below:

[0032] The present invention Figure 1 As shown in the top view, it includes a mobile vehicle 1, a pallet fork 3 and a palletizing conveyor line.

[0033] The pallet fork is installed on the mobile vehicle. The pallet fork picks up the pallet goods on the stacking conveyor line, and is driven by the components on the mobile vehicle to go deep into the container, and then the pallet is placed to realize the function of container pallet loading.

[0034] Specifically, the mobile vehicle 1 of the present invention includes a chassis, a steering seat, and a forward extension arm. The chassis is U-shaped when viewed from above, and mobile wheel groups are arranged at the bottom of both sides of the U-shape, and loading rails 2 are correspondingly arranged at the bottom. The loading rails 2 are arranged in pairs and in parallel. The mobile wheel groups are guide wheel groups, and the guide wheel groups on both sides of the chassis are respectively on the two loading rails 2 and move back and forth. The truck container 8 drives into the space between the two loading rails 2, that is, the front end space of the U-shape for loading operations.

[0035] A steering seat is provided at the bottom of the U-shape, and a forward arm is provided on the steering seat. The forward arm can be rotated to both sides at a certain angle on the steering seat. The pallet fork 3 is provided at the front end of the forward arm. The steering seat function enables the pallet fork to insert and take pallet goods from the palletizing conveyor line coming from any direction.

[0036] The pallet fork 3 at the front end of the forward extension arm is at the U-shaped opening of the chassis. When the loading container 8 enters the U-shaped front end space of the chassis, the forward extension arm drives the pallet fork 3 deep into the container 8 to the deepest position, so that the pallet fork can penetrate into the container to unload the pallet cargo.

[0037] In the present invention, the forward extension arm extends deep into the container and swings left and right without a front-end lifting function. Here, the pallet fork 3 is a liftable pallet fork 3 so as to achieve safe landing of pallet cargo.

[0038] Furthermore, in order to connect the palletizing conveyor line and the pallet fork, a track section conveyor line 5 is also provided, and the track section conveyor line 5 and the palletizing conveyor line are on the same straight line.

[0039] The track section conveyor line 5 is divided into a bottom trolley and an upper track conveyor. The axle of the moving wheel is connected to the drive motor through a synchronous transmission mechanism, and the moving wheel is provided with a corresponding conveyor rail.

[0040] The track section conveyor line and the stacking section conveyor line are on the same straight line. There are two ways to arrange them with the loading track. One is that the track section conveyor line 5 is perpendicular to the loading track 2, such as Figure 1 In the middle layout, the track section conveyor line 5 moves between the middle and edge of the loading track 2. When the track section conveyor line 5 moves to the edge of the loading track 2, it connects with the palletizing section conveyor line. When the track section conveyor line 5 moves to the middle position of the loading track 2, it is on the movement path of the pallet fork 3.

[0041] Another, such as Figure 4 In the middle arrangement, the stacking conveyor line 4 is parallel to the loading track 2 and is located between the two loading tracks 2. The forward extension arm can rotate 360 ​​degrees around the steering seat.

[0042] At the loading end of the palletizing conveyor line, a palletizing robot 6 is set up. The palletizing robot 6 places the bagged or boxed goods on the pallet, and the pallet is placed at the end position of the palletizing conveyor line 4. After the pallet is palletized, it is transported by the palletizing conveyor line 4 to the end loading position.

[0043] In order to further ensure the neatness of the goods on the pallet and the safety during insertion and removal, a pallet shaping machine is provided on one side of the palletizing conveyor line 4.

[0044] The loading method of the container pallet loader of the present invention is described, which includes the following steps:

[0045] 1) The pallet is placed at the palletizing position of the palletizing conveyor, and the palletizing robot 6 places the goods on the pallet;

[0046] 2) The palletizing conveyor drives the palletizing pallet to move, and the pallet is shaped at the palletizing shaping machine, and then continues to be conveyed to the end;

[0047] 3) The mobile vehicle 1 moves and the forward extension arm on the mobile vehicle 1 rotates to the working position of the pallet fork 3.

[0048] 4) Pallet fork 3 picks up the pallet cargo and lifts it up;

[0049] 5) The mobile vehicle 1 moves, driving the forward extension arm and the stacking pallet into the container 8;

[0050] 6) The forward extension arm on the mobile vehicle 1 rotates to the placement position, and the pallet fork 3 puts down the stacking pallet;

[0051] 7) The mobile vehicle 1 moves, driving the forward extension arm and the pallet fork 3 to exit the container 8, and repeat steps 1-6 to load the container.

[0052] In the above steps, in step 3, the pallet fork is inserted into the pallet through the rail conveyor line. Specifically, the stacking conveyor continues to transport the pallet goods, the rail conveyor line moves to the end position of the stacking conveyor and receives the pallet goods, and then the rail conveyor line moves to the pallet, and inserts the fork of the pallet fork into the rail conveyor line through the pre-set pallet fork position, and then rotates the mobile trolley to a suitable angle and places it deep into the container to realize container loading of the stacked pallet.
