Wherein, an avoiding groove 10 is formed in the lower sliding plate corresponding to each left clamping hand 91, and a sliding mechanism for simultaneously driving the two sliding plates 8 to move in the same direction or in the opposite direction is further arranged on the rotating frame 5.

[0019] The wood pallet is made of logs, generally comprises a panel, a bottom plate and a cushion block, forms a stable load bearing structure, and is convenient for forklift handling. The downstream station of the device is a bottom plate unloading station. When the wood pallet is assembled, the device can be used to sequentially and orderly feed a plurality of sets of cushion blocks to the cushion block feeding station. The cushion blocks are conveyed to the bottom plate unloading station. A bottom plate is arranged on the same set of cushion blocks. Finally, the panel is laid on a plurality of bottom plates, and a wood pallet is assembled.

[0020] In the device, a plurality of pairs of baffles are arranged on the upper portion of the machine table opposite to the conveying table. The conveying channels are formed between the same pair of baffles. The distances between each conveying channel are equal. There are four conveying channels in the drawing. A left and right pair of clamping hands are arranged in front of each conveying channel. A row of cushion blocks is arranged on the conveying table in each conveying channel.

[0021] In the structure, the top of the right clamping hand in each pair of left and right clamping hands is mounted on the lower sliding plate, the top of the left clamping hand is mounted on the upper sliding plate, and the lower sliding plate has an avoiding groove corresponding to each left clamping hand. The left clamping hand is located in the avoiding groove. In actual conditions, when the sliding mechanism drives the two sliding plates to move towards each other, all the same pairs of clamping hands move towards each other. Similarly, when the sliding mechanism drives the two sliding plates to move in the opposite direction, the same pairs of clamping hands move in the opposite direction. Therefore, the distance between each pair of clamping hands can be adjusted according to the width of the conveying channel, and the adaptability of the clamping hand is high.

[0022] When the device is used to load the cushion block to the cushion block loading station, the blocking assembly is located at the blocking position. First, under the conveying of the conveying table, the cushion blocks in the conveying channel are all moved forward by one station, then the conveying table stops working, each pair of clamping hands has a current cushion block, the sliding mechanism drives the upper and lower sliding plates to move in the same direction, the same pair of clamping hands moves towards the current cushion block, and the blocking assembly moves forward to form an avoidance. The rotating frame rotates forward, the clamping hand transfers the current cushion block to the cushion block loading station, and the same group of current cushion blocks are arranged at equal intervals. Then the two sliding plates move in the opposite direction, the same pair of clamping hands releases the current cushion block, the rotating frame rotates backward, and then the blocking assembly returns to the blocking position. The conveying table continues to move the cushion blocks in the conveying channel forward by one station, and the next cushion block is sent to the same pair of clamping hands in front of it to wait to be loaded. In this process, the blocking assembly plays a blocking role, which can prevent the cushion blocks from falling off the front end of the conveying table to the ground during conveying.

[0023] In addition, the inner side below the clamping hand is provided with an anti-skid clamping piece 11, which can make the clamping hand more stable during clamping the cushion block and prevent the cushion block from falling off during clamping.

[0024] As a specific structure, as Figures 1-2 Both sides of the machine table 1 are provided with a drive box 12, the bottom of the rotating frame 5 is rotatably installed on the same side of the drive box 12, and the drive box 12 is provided with a rotating cylinder for driving the rotating frame to rotate.

[0025] As Figure 1 、 Figure 3 Wherein a guide groove 13 is formed on the upper sliding plate 8, the sliding mechanism includes a lead screw 14 and a pair of guide rods 15 installed in the rotating frame 5, the guide rods 15 are fixedly installed, the lead screw 14 is rotatably installed, and the lead screw 14 has two opposite threaded sections, the lead screw 14 is provided with a pair of left and right sleeve 16, the guide rod 5 passes through the sleeve 26, the sleeve 16 is provided with a connecting plate 17 downward, the connecting plate 17 is provided with a connecting rod 18, the right connecting rod 18 passes through the guide groove 13 and is connected with the lower sliding plate 8, the left connecting rod 18 is connected with the upper sliding plate 8, and the rotating frame 5 is further provided with a driving motor 19 for driving the lead screw to rotate.

[0026] In the above structure, the sliding mechanism comprises a screw rod and a pair of guide rods installed vertically, and a pair of screw sleeves are inserted through the screw rod and the guide rods. The screw rod and the guide rods are arranged in a triangle shape, and the triangle shape is stable, so that the screw sleeves are more stable during movement. In addition, the screw rod is formed with two thread sections in opposite directions. When the driving motor drives the screw rod to rotate in the same direction, the two screw sleeves move towards each other along the length direction of the screw rod, and the two connecting rods drive the two sliding plates to move towards each other, so that all the same pairs of clamping hands move towards each other to clamp the cushion block. Similarly, when the driving motor drives the screw rod to rotate in the opposite direction, all the same pairs of clamping hands move in the opposite direction to release the cushion block.

[0027] Further, as a preferred structure, Figure 1 The material blocking assembly comprises a pair of fixed frames 20 installed on the side walls of the rack of the conveying table 2. The inner walls of the fixed frames 20 are provided with material blocking cylinders 21 which are inclined downward and forward. The driving shafts of the two material blocking cylinders 21 are provided with L-shaped material blocking plates 22.

[0028] When the cushion block in the conveying channel is moved forward by one station by the conveying table, the material blocking plates are located in the blocking position before this time, and the material blocking plates are arranged towards the conveying table and play a blocking role. In this way, the cushion block can be prevented from falling from the front end of the conveying table to the ground during conveying. After the same pair of clamping hands clamp the cushion block, the two material blocking cylinders drive the material blocking plates to move downward and forward by a small distance at the same time, and the material blocking plates are away from the conveying table by a small distance to form an avoidance, so that the clamping hands can smoothly transfer the cushion block to the feeding station during the forward rotation of the rotating frame.

[0029] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
