Description

Technical Field

[0001] The utility model belongs to the technical field of transportation machinery, and particularly relates to a box holding machine. Background Art

[0002] When handling large objects, it is very troublesome. For example, for refrigerators, air conditioners, etc., after the complete products are packed in boxes, they need to be transported and moved. If done manually, the labor cost is high, or using traditional hoisting methods is very inconvenient. First, it is easy to damage the products, and second, the efficiency is very low. Therefore, there are existing box holding machines for the transportation and movement of such products. They mainly connect the clamping robot arm through a moving mechanism to clamp and lift items such as refrigerators and air conditioners for movement.

[0003] There is a type of existing box holding machine that needs to flip the item by 90° during transportation. For rectangular box-shaped items like refrigerators, sufficient flipping space needs to be ensured during flipping. Therefore, basically, the flipping action is carried out when the lifting mechanism rises to the highest position. However, during long-term operation, due to reasons such as slipping, mechanical wear, or aging of the power mechanism, there is a situation where the flipping mechanism starts the flipping action when the lifting mechanism fails to lift the box to the highest position. At this time, it is extremely easy to cause the box to collide with the ground during flipping, resulting in product damage. And serious losses will be caused if this situation cannot be detected in time. Summary of the Utility Model

[0004] Aiming at the above existing technical problems, the utility model provides a box holding machine to solve the problem of the risk of collision with the ground when the existing box holding machine flips and transports the box. This box holding machine can identify the position of the clamping frame before flipping, effectively eliminating the collision problem caused by insufficient rising.

[0005] The utility model provides a box holding machine, which comprises a support frame, a horizontal traveling frame, a lifting device, a clamping frame, a first cylinder, clamping arms, an infrared transmitting head and an infrared receiving head. The horizontal traveling frame is horizontally movably arranged on the top of the support frame. The lifting device is arranged on the horizontal traveling frame. The clamping frame is connected to the bottom of the lifting device, and the clamping frame is driven by the lifting device to move up and down. The infrared transmitting head and the infrared receiving head are respectively arranged on two sides of the support frame facing each other. When the clamping frame rises to the topmost position, the clamping frame is located between the infrared transmitting head and the infrared receiving head. The number of the clamping arms is two, and the two clamping arms are arranged at intervals and horizontally slidably at the bottom of the clamping frame. The first cylinder is used to drive the two clamping arms to approach or move away from each other. A rotating shaft, a suction cup, a connecting rod and a second cylinder are arranged on the clamping arm. The rotating shaft is rotatably arranged on the clamping arm. The suction cup is connected to one end of the rotating shaft, and the suction cups on the two clamping arms face each other. One end of the connecting rod is connected to the other end of the rotating shaft, and the other end of the connecting rod is rotatably connected to the second cylinder. The other end of the second cylinder is rotatably connected to the clamping arm.

[0006] Further, the box holding machine further comprises a controller, the controller is electrically connected to the infrared receiving head, and the controller is used to control the first cylinder and the second cylinder.

[0007] Further, the lifting device comprises a lifting frame, a rack, a gear and a motor. The lifting frame is slidably arranged up and down on the horizontal traveling frame. The rack is vertically arranged on the lifting frame. The motor is arranged on the horizontal traveling frame. The motor is connected to the gear, and the gear meshes with the rack.

[0008] When the box holding machine performs the transportation and flipping operations of the box body, the horizontal traveling frame can be used to transport the clamping frame above the box body, and the clamping arms are located on both sides of the box body. The first cylinder is used to drive the two clamping arms to approach each other to clamp the box body. The lifting device is used to drive the box body to rise. When the clamping frame rises to the topmost position, the clamping frame is located between the infrared transmitting head and the infrared receiving head. At this time, the information of the infrared receiving head can be used to determine that the clamping frame has risen to the topmost position. Then, the second cylinder is used to drive the rotating shaft to rotate so as to drive the box body to flip, which can avoid the knocking problem caused by the failure to rise in place.
