Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a pallet detection device. Background Art

[0002] Pallets are horizontal platform devices used for packaging, stacking, handling and transportation of goods and products as unit loads. The lack of stability of pallets will result in the safety of goods not being guaranteed during the logistics process. In reality, staff often use regular inspection methods to check pallets, judge the stability of pallets and decide whether to replace them. This is labor-intensive and requires operators to rely on tools for inspection. Utility Model Content

[0003] The purpose of the utility model is to provide a pallet detection device to solve the above-mentioned technical problems, so as to achieve the effect of freeing manpower and efficiently detecting pallets.

[0004] In view of this, the utility model provides a pallet detection device, including a conveying device for conveying a pallet body along a conveying direction, a detection component is arranged on the conveying device along the conveying direction, the detection component includes a mounting plate arranged laterally on a frame, a plurality of detection units are arranged on the mounting plate, the detection units are arranged on the mounting plate corresponding to the bottom feet of the pallet body, and a laser transmitter and a laser receiver are also arranged on the mounting plate corresponding to the detection units.

[0005] In the present technical solution, the conveying device is a roller conveyor belt, on which the pallet body is placed, and the pallet body is transported along the conveying direction of the conveying device. A detection component is arranged on the conveying device along the conveying direction, including a mounting plate and a detection unit arranged on the mounting plate corresponding to the bottom support feet of the pallet body. A laser transmitter and a receiver are also arranged. When the support feet of the pallet body act on the detection unit, it can be determined whether the support feet of the pallet body are damaged. It is no longer necessary for operators to inspect the pallets one by one with tools, which frees up manpower and improves efficiency.

[0006] In the above technical solution, further, the detection component includes a mounting plate, which is connected to the frame, and first support plates are symmetrically arranged on both sides of the mounting plate, a connecting rod is arranged between the first support plates on both sides, a detection unit is passed through the connecting rod, and a plurality of mounting holes are arranged on the mounting plate.

[0007] In this technical solution, the detection unit is slidably connected to the mounting plate and can perform detection on pallet bodies of different specifications. The detection unit can change the position of the detection unit on the mounting plate according to the bottom feet of the pallet bodies of different specifications, and the detection unit and the mounting plate are threadedly connected corresponding to the mounting holes on the mounting plate.

[0008] In the above technical solution, further, the detection unit includes a base plate, on which a second support plate is symmetrically arranged, and between the two second support plates, a plurality of detection plates arranged in an array are arranged, and the detection plate and the second support plate are respectively provided with a first through hole and a second through hole corresponding to the connecting rod, and support components are also arranged on both sides of the mounting plate.

[0009] In this technical solution, the support assembly is used to support and transmit the pallet body under inspection. Its height is lower than the inspection plate. The inspection plate and the second support plate are slidably connected to the connecting rod. The second support plate and the seat plate are fixedly connected to facilitate the overall movement of the inspection unit. The connecting rod can play a limiting role.

[0010] In the above technical solution, further, the second support plate is provided with a detection hole, and the detection plate is provided with a positioning hole.

[0011] In the present technical solution, the detection hole is located on one side of the second through hole. In the present embodiment, the conveying direction of the tray body is from left to right, so the detection hole is located on the right side of the second through hole. When the tray body squeezes and passes the detection plate from left to right, the detection plate tilts to the left. If the bottom support foot of the tray is not damaged, at this time, the detection hole and the positioning hole are aligned, and a laser transmitter is set on one side to emit laser, and the laser passes through the above-mentioned detection hole and positioning hole and is received by the laser receiver set on the opposite side. On the contrary, if the bottom support foot of the tray is damaged, the detection hole and the positioning hole are not aligned, and the laser receiver will not receive the laser emitted by the laser transmitter.

[0012] In the above technical solution, further, the positioning holes and the detection holes on the detection plate are arranged in the vertical direction, and the volume of the upper end of the detection plate is smaller than that of the lower end.

[0013] In the technical solution, in the embodiment, the shape of the detection plate is specifically pear-shaped, and both the upper and lower ends are arc structures. The volume of the upper end of the detection plate is smaller than the lower end, which helps to quickly reset the tray body after leaving.

[0014] In the above technical solution, further, the support assembly includes third support plates symmetrically arranged on both sides of the detection plate, there are two third support plates on one side of the detection plate, and a support roller is rotatably arranged between the two third support plates.

[0015] In this technical solution, the rotation direction of the support roller is consistent with the direction of the conveying device, and the height of the support roller is lower than the height of the detection plate.

[0016] In the above technical solution, further, a cleaning roller is included. The cleaning roller is rotatably arranged on the bracket, and one end of the cleaning roller is driven by the first motor.

[0017] In the present technical solution, the first motor is fixedly connected to the support frame, and the output end passes through the support and is coaxially fixedly connected to the cleaning roller. The cleaning roller is arranged between any two rollers in the roller conveyor belt and is located in front of the detection component. It can clean the bottom of the tray body to prevent dust and waste debris adhering to the bottom from affecting the detection results.

[0018] In the above technical solution, further, a slide groove is provided on the mounting plate along the direction of the connecting rod, and a convex strip is correspondingly provided on the detection unit seat plate.

[0019] In the present technical solution, by providing a sliding groove and a protrusion, further limiting is achieved in cooperation with a connecting rod to ensure stability when the detection unit is moved.

[0020] The beneficial effects of the utility model are:

[0021] 1. The conveying device is a roller conveyor belt, on which the pallet body is placed, and the pallet body is transported along the conveying direction of the conveying device. A detection component is arranged on the conveying device along the conveying direction, including a mounting plate and a detection unit arranged on the mounting plate corresponding to the bottom support feet of the pallet body. A laser transmitter and a receiver are also arranged. When the support feet of the pallet body act on the detection unit, it can be concluded whether the support feet of the pallet body are damaged. It is no longer necessary for operators to inspect the pallets one by one with tools, which frees up manpower and improves efficiency.

[0022] 2. The detection unit is slidably connected to the mounting plate, and can detect pallets of different specifications. The detection unit can change the position of the detection unit on the mounting plate according to the bottom feet of the pallet body of different specifications.
