Description

Technical Field

[0001] The utility model belongs to the technical field of transfer machines, and in particular relates to a pallet transfer machine. Background Art

[0002] The pallet transfer machine is a highly efficient automatic handling equipment. It uses a transfer machine to transport pallet items from one workstation to another. It is mainly used for transmission between equipment. The transfer machine equipment adopts PLC programmable control, so that pallet items can easily enter and exit the horizontal and vertical conveyor racks without collision, extrusion, etc. The pallet items enter from the left side of the equipment and are transported to the upper position of the longitudinal conveyor rack in the equipment. At this time, the roller stops rotating, and then the hydraulic cylinder on the longitudinal conveyor rack lifts it, so that the conveyor belt on the rotating longitudinal conveyor rack lifts the pallet items, and then the rotating conveyor belt transports the pallet items to the back direction of the box equipment, realizing a 90-degree turn of the pallet items, thereby improving the transportation efficiency of the pallet items. Chinese patent application number 202121914294.0 discloses a pallet transfer machine that can change the direction of the pallet. It can be seen that the content describes a pallet transfer machine.

[0003] When the existing pallet transfer machine is in use, the pallet items enter from the left side of the transfer machine equipment and enter the position above the longitudinal conveyor frame in the transfer machine through the rotation of the roller. Then the roller stops rotating, and the longitudinal conveyor frame rises under the lifting action of the hydraulic cylinder to lift the pallet items. Then the pallet items are transported to the back of the transfer machine equipment through the rotating conveyor belt. However, after some pallet items are transported to the top of the longitudinal conveyor frame, they may continue to move to the right side of the transfer machine equipment due to their own inertia. The pallet items do not stop in time. At this time, the position of the pallet items after moving changes. When the longitudinal conveyor frame rises, it is difficult for the conveyor belt to fully contact the pallet items, resulting in a problem that affects the conveying effect of the pallet items. For this reason, we propose a pallet transfer machine. Utility Model Content

When in use, a second reduction motor is installed on the longitudinal conveyor frame 106, and the second reduction motor can drive the conveyor belt 104 to rotate. Four groups of hydraulic cylinders 102 are arranged between the bottom frame 103 and the longitudinal conveyor frame 106. A limit assembly is arranged on the longitudinal conveyor frame 106. The limit assembly includes a limit member and two groups of lifting members. The limit member is located at the top of the lifting member. The lifting member is located at the top of the longitudinal conveyor frame 106. The limit member includes a top plate 200. The side of the top plate 200 is fixedly provided with a side plate 203. A plurality of groups of balls 202 are arranged on the side plate 203, and a plurality of groups of rolling holes are opened on the side of the side plate 203. When in use, the balls 202 will roll inside the rolling holes, and the balls 202 are located inside the rolling holes. The lifting member includes a lower rod 201 and a cylinder 205. The bottom of the lower rod 201 penetrates into the cylinder 205, and the top plate 200 is fixed to the top of the lower rod 201. A screw mouth is opened inside the cylinder 205, and a screw rod 204 is arranged inside the screw mouth. When in use, the screw rod 204 is screwed together with the screw mouth through a thread. The end of the rod 204 extends to the surface of the lower rod 201. Through the designed limiting assembly, it is convenient to install the side plate 203 and the ball 202 for blocking the pallet items near the right side of the transfer machine during use. When the pallet items being transported tend to continue to move to the right due to their own inertia, they contact the ball 202 on the side plate 203 to block the pallet items, making it convenient for the longitudinal conveying mechanism to rise and transport the pallet items to the back of the transfer machine, thereby improving the transfer effect of the transfer machine on the pallet items.

[0024] In this embodiment, preferably, a fixing plate 300 is fixedly provided at the bottom of the cylinder 205, and the fixing plate 300 is fixedly connected to the longitudinal conveying frame 106 by screws. By combining the designed fixing plate 300 and the screws, it is convenient to disassemble and assemble the limit assembly during use, and the limit assembly can be used according to different situations.

[0025] In this embodiment, preferably, two groups of pillars are fixedly provided at the bottom of the transverse conveying frame 100, and the base frame 103 is fixed on the pillars.

[0026] The working principle and use process of this utility model:

[0027] When the utility model is in use, when the pallet items enter from the left side of the transfer machine equipment and enter the upper position of the longitudinal conveying frame 106 in the transfer machine through the rotation of the roller 101, the roller 101 then stops rotating. At this time, if the pallet items have a tendency to continue to move to the right due to their own inertia, the pallet items will be blocked and limited by the ball bearings 202 on the side plate 203 to prevent the pallet items from moving to the right. Then, the longitudinal conveying frame 106 rises under the lifting action of the hydraulic cylinder 102 to lift the pallet items. At this time, the lower surface of the pallet items no longer contacts the roller 101. Then, the pallet items are transported to the back side of the transfer machine equipment through the rotating conveyor belt 104. At this time, the ball bearings 202 roll to reduce the friction effect on the pallet items.

[0028] The limit assembly can be removed by loosening the screws on the fixing plate 300 , and the limit assembly can be installed by tightening the screws.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
