Description

Technical Field

[0001] This utility model belongs to the field of material handling equipment technology, specifically, it relates to an improvement in the structure of a material handling system for a material transfer line. Background Technology

[0002] The existing production facility has a material feeding position and a material discharging position for the material tray. At the material feeding position, multiple layers of material trays are arranged to feed the material through the material trays. After the material trays are fed, the empty material trays can be picked up by the corresponding robotic arms and placed on one side.

[0003] At the same time, corresponding empty material trays are also set up at the material use positions for material feeding. After one of the material trays is full, it is picked up by a robotic arm and moved to the conveyor line for delivery.

[0004] The material trays at the feeding and discharging points are used separately. Empty material trays at the feeding point are sorted by operators and then moved to the discharging point for use. When the material tray usage is large, it requires a lot of manpower and is labor-intensive, which greatly reduces production efficiency.

[0060] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0061] In some embodiments of this application, a material handling system is proposed for a tray transfer line, the tray transfer line including a feeding position and a discharging position. The feeding position of the tray transfer line is arranged along a first direction, and the discharging position is arranged along a second direction.

[0062] A material tray is placed at the feeding position to achieve material feeding, and the material tray at the feeding position is full of material.

[0063] An empty tray needs to be placed at the material feeding position to hold the materials on the production line.

[0064] The material handling system is used to transfer material trays in the material tray transfer line.

[0065] The material conveying system includes an empty material tray conveyor line 100, a first material conveying mechanism, and a second material conveying mechanism, which are respectively arranged at both ends of the empty material tray conveyor line 100.

[0066] In use, the first material conveying mechanism places the empty material trays that have been used up at the material dispensing position onto the empty material tray conveyor line 100, and then transports the material trays to the position of the second material conveying mechanism via the empty material tray conveyor line 100. The second material conveying mechanism then places the material trays at the material dispensing position for material dispensing.

[0067] In some embodiments of this application, the first material conveying mechanism includes:

[0068] The first material handling unit 200 is mainly used for picking up and placing materials;

[0069] The first moving mechanism is connected to the first material conveying unit 200 and is used to drive the first material conveying unit 200 to move along the first direction and the height direction, so as to transfer the empty material tray at the material supply position to the empty material tray conveying line 100.

[0070] The first moving mechanism is mainly used to drive the first material conveying unit 200 to move.

[0071] By moving along the first direction, it can drive the first material conveying unit 200 to move between the material supply position and the empty material tray conveyor line 100.

[0072] It is movable along the height direction and can be used to drive the first material handling unit 200 to pick up and put down materials.

[0073] In some embodiments of this application, the second material conveying mechanism includes:

[0074] The second material handling unit 400 is used to grab materials.

[0075] The second moving and rotating mechanism 500 is connected to the second material conveying unit 400 and is used to drive the second material conveying unit 400 to move along the second direction and the height direction and rotate along the Z direction, so as to transfer the empty material tray at the empty material tray conveying line 100 and position it above the material tray at the material use position.

[0076] The second moving and rotating mechanism 500 drives the second material conveying unit 400 to move along the second direction, so that the second material conveying unit 400 can move the transfer tray at the material discharge position and the empty material tray conveying line 100.

[0077] By moving the second operating unit along the height direction, the corresponding material tray picking and placing actions can be performed.

[0078] By driving the second material conveying unit 400 to rotate, the material tray can be rotated at a certain angle so that when the empty material tray is placed on the material tray filled with material below, it will not damage the material in the material tray.

[0079] The material tray for placing materials has an internal cavity with multiple material receiving slots. Multiple first protrusions are arranged on the outer walls of the material tray cavity, and a first recess is formed between adjacent first protrusions. There are second protrusions on the inner wall of the cavity, and their height is higher than the top surface of the material receiving slots.

[0080] In normal placement, the second protrusion of the outer tray of two adjacent trays is inserted into the first recess of the inner tray and they are interlocked, so that the inner tray falls into the outer tray at least partially.

[0081] However, if the trays are already filled with material, stacking them one on top of the other will cause pressure damage to the material inside.

[0082] Therefore, in this embodiment, the second moving and rotating mechanism 500 is configured to drive the second material conveying unit 400 to rotate. In this way, the second moving and rotating mechanism 500 can drive the second material conveying unit 400 and the material tray to rotate 180 degrees, so that the second protrusion and the first protrusion of the upper and lower material trays are positioned correspondingly. This prevents the inner material tray from falling into the inner material tray, thus preventing damage to the material.

[0083] The second moving and rotating mechanism 500 selectively drives the second material conveying unit 400 to rotate. For example, when the empty material tray transferred to the discharge position is the first material tray, the second material conveying unit 400 can directly move the material tray horizontally. When the second material conveying unit 400 is transferring the second material tray, it is necessary to rotate the second material tray 180 degrees to make it staggered from the first material tray. When the second material conveying unit transfers the third material tray, it is not necessary to rotate it 180 degrees. This cycle is repeated so that the multiple stacked material trays are staggered to ensure that the material inside the material tray is not pressed down.

[0084] The material handling system in this embodiment includes an empty material tray conveyor line 100, a first material handling mechanism, and a second material handling mechanism. The first material handling mechanism can move along a first direction and in the height direction to transfer empty material trays that have been used up at the feeding position to the empty material tray conveyor line 100. The empty material tray conveyor line 100 conveys material trays along a second direction to a position close to the second material handling mechanism. The second material handling mechanism can move along the second direction and in the height direction to grab the empty material trays on the empty material tray conveyor line 100, and then selectively rotate the material trays according to the actual situation, so that the stacked material trays are staggered, so that the empty material trays can be directly discharged at the discharging position, and the empty material trays at the feeding position can be directly transferred to the discharging position for use without the need for separate sorting and grabbing of empty material trays. At the same time, it eliminates the step of loading empty material trays at the discharging position, reduces the consumption of manpower and material resources, and greatly improves production efficiency.

[0090] Two sets of empty material tray transmission devices are provided, both of which are connected to the transmission shaft 111. The two sets of empty material tray transmission devices are respectively assembled on the two empty material tray support frames 120.

[0091] When the empty material tray drive 110 rotates, it drives the transmission shaft 111 connected to it to rotate, and the rotation of the transmission shaft 111 drives the two empty material tray transmission devices to operate.

After being led out from the second guide pulleys 160, one end is wound onto one of the driven drive pulleys 170 and the other end is wound onto the other driven drive pulley 170.
