Description

Technical Field

[0001] This utility model belongs to the field of material tray transfer technology, specifically, it relates to a material tray transfer line structure that can realize automatic loading and unloading of material trays. Background Technology

[0002] In existing material tray loading and unloading systems, if material tray loading and unloading are required at both the feeding and unloading positions, lifting loading and unloading devices will be arranged at the corresponding feeding and unloading positions. For example, the empty material tray lifting mechanism (10) structure disclosed in patent document CN105293081A includes a first lifting motor (11), a first lead screw (12) connected to the first lifting motor and vertically arranged, a first support plate (13) screwed onto the first lead screw and horizontally arranged, and a first guide device (14) for guiding the lifting and lowering of the first support plate. The empty material tray is carried on the first support plate.

[0003] The lifting and unloading equipment installed at the feeding position only has a lifting function. When a full-loaded material tray needs to be placed on this lifting and unloading equipment, it is necessary to manually assist in moving it onto the equipment. After the material tray is fed, it is manually moved down.

[0004] Similarly, empty material trays at the unloading position also need to be manually moved to the lifting and unloading equipment, then lifted to the unloading height to unload the material. After the unloading is full, the lifting and unloading equipment is lowered and manually moved down.

[0005] The feeding and unloading positions are separate locations with their own lifting and unloading equipment. The feeding of full-loaded trays and the unloading of empty trays at the feeding position, as well as the feeding of empty trays and the unloading of full-loaded trays at the unloading position, are all done manually. This not only consumes a lot of manpower, but also requires each tray to be handled and unloaded separately, which greatly reduces the efficiency of loading and unloading.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0044] Two sets of empty material tray transmission devices are provided, both of which are connected to the transmission shaft. The two sets of empty material tray transmission devices are respectively assembled on the two empty material tray support frames.

[0045] In some embodiments of this application, the empty material tray transmission device includes:

[0046] Active pulley;

[0047] Two pressure pulleys are provided, symmetrically arranged on both sides of the drive pulley and located below the drive pulley;

[0061] The second guide rail and the second guide slider slidably connected above it are connected by a second connector and a second transmission belt.

[0062] In some embodiments of this application, the second moving and rotating mechanism includes: a rotating unit seat and a rotating power component connected to the rotating unit seat, wherein the rotating power component is connected to the second material conveying unit via a rotating connector.

[0063] Compared with the prior art, the advantages and positive effects of this utility model are:

[0064] The automatic loading and unloading tray transfer line of this utility model can control the first support to move down to the first receiving part when loading the tray at the feeding position. Then, through the first lateral moving mechanism and the corresponding AGV or trolley equipment, the tray is automatically received and transported along the horizontal direction. After the tray is transported to the position, the first support located in the first receiving part rises to support the tray and moves it upward until the top tray moves to the feeding position for feeding, thus realizing the automatic loading of the full-load tray.

[0065] After the full material tray is used up, the empty material tray is directly transferred to the unloading position through the material tray transfer unit for unloading, realizing the automatic unloading of empty material trays generated at the material supply position;

[0066] For feeding empty material trays at the feeding position, the empty material trays at the feeding position are directly placed onto the second support by the material tray transfer unit, thus realizing automatic feeding of empty material trays at the feeding position.

[0067] When the full-loaded material tray at the feeding position is unloaded, the second support component of the second material tray support mechanism drives the material tray to move down to the second receiving part of the second transverse conveying mechanism, and then the second transverse conveying mechanism automatically outputs the material tray outward, realizing the automatic unloading of the full-loaded material tray;

[0068] The automatic loading and unloading of material trays at the feeding and unloading positions is achieved through the cooperation of the first material tray support mechanism, the empty material tray transfer unit, and the second material tray support mechanism, thereby improving production efficiency.

[0069] In addition, the first support in this utility model is liftable. During feeding, multiple material trays can be set on the first support. After the top full material tray is used up, it continues to move upward by one material tray height so that the material trays at the lower level can continue to feed until all material trays are fed, thus extending the feeding interval time.

[0070] Similarly, the second support is liftable, so that after the material tray at the top position is full, it can be lowered by one tray height to continuously support new empty material trays. This allows for the simultaneous support of multiple material trays without having to unload a single tray, thus extending the unloading interval and improving production efficiency.

[0071] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0085] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0086] In some embodiments of this application, an automatic loading and unloading tray transfer line is proposed, comprising: a tray line base 600, and a first tray support mechanism 700, a second tray support mechanism 800, and an empty tray transfer unit arranged at the tray line base 600.

[0087] The first tray support mechanism 700 is used to realize automatic tray feeding, the second tray support mechanism 800 is used to realize automatic tray unloading, and the empty tray transfer unit between the two is used to transfer the empty trays used up at the first tray support mechanism 700 to the second tray support mechanism 800 for unloading.

[0088] The material tray line base 600 is used to support the entire material tray transfer line. A feeding position 610 and a discharging position 620 are formed at the material tray line base 600.

[0089] The feeding position 610 is used to place the feeding tray, and the tray at the feeding position 610 is fully loaded with material.

[0090] A material tray for discharging material is placed at the material discharging position 620. The material tray at the material discharging position 620 is an empty material tray to facilitate material discharging.

[0091] In some embodiments of this application, the feed tray base 600 includes:

[0092] Inner frame of the matrix;

[0093] And the outer frame of the substrate, and an accommodating space is formed between the outer frame of the substrate and the inner frame of the substrate.

[0094] The feeding position 610 is located at one end of the accommodating space, and the discharging position 620 is located at the other end of the accommodating space.

[0095] The first material tray support mechanism 700, located at the material feeding position 610, is used for material feeding and includes:

[0096] The first transverse conveying mechanism 710 is arranged horizontally and is used to automatically receive the material tray. A first receiving part 711 is formed on the side of the first transverse conveying mechanism 710, and the first receiving part 711 is a first receiving space.

[0097] The first support member 720 carries multiple fully loaded material trays for feeding on top. It is liftable. When the first support member 720 moves to the position of the first transverse conveying mechanism 710, and the first support member 720 is placed in the first receiving part 711, its top surface height is less than the top surface height of the first transverse conveying mechanism 710.

[0098] When the first support member 720 descends to the bottom position, it can be accommodated by extending into the first receiving part 711. At the same time, its top surface is lower than the top surface of the first transverse conveying mechanism 710, which can ensure that the first transverse conveying mechanism 710 can input materials normally without being interfered with by the first support member 720.

[0099] The first horizontal conveying mechanism 710 is arranged horizontally and can be used to connect to the material trays directly transferred from AGV and other transfer equipment. By moving the first horizontal conveying mechanism 710, the material tray can be automatically conveyed to the inside of the first material tray support mechanism 700. By raising the first support member 720, the material tray conveyed to the first horizontal conveying mechanism 710 is moved upward and lifted, so as to drive the material tray to the set material tray height for feeding.

[0100] Through the cooperation of the first transverse conveying mechanism 710 and the first support member 720, the material trays that have been transferred are automatically fed to the set height for material supply.

[0101] The second material tray support mechanism 800 is arranged at the material discharge position 620 and includes:

[0102] The second transverse conveying mechanism 810 is arranged horizontally and is used to convey the material tray outward. A second receiving part 811 is formed on the side of the second transverse conveying mechanism 810.

[0103] The second support member 820 carries a material tray on top and is liftable. When the second support member 820 moves to the position of the second transverse conveying mechanism 810, the second support member 820 is placed in the second receiving part 811 and the height of its top surface is less than the height of the top surface of the second transverse conveying mechanism 810.

[0104] When it is necessary to convey the material tray outward, the second support member 820 can be moved downward, causing the material tray above it to move downward. When the second support member 820 moves into the second receiving part 811, since its top surface is lower than the second transverse conveying mechanism 810, the material tray above it will be supported on the second transverse conveying mechanism 810. The second transverse conveying mechanism 810 will automatically output the material tray outward.

[0105] An empty material tray transfer unit is arranged between the first material tray support mechanism 700 and the second material tray support mechanism 800, and is used to transfer the empty material tray on the first support 720 to the second support 820.

[0106] By setting up the empty material tray transfer unit, the empty material trays generated at the feeding position 610 can be directly reused and transferred directly to the discharging position 620 for material discharge. This not only saves the operation steps of grabbing the empty material tray at the feeding position 610, but also eliminates the step of transferring spare empty material trays to the discharging position 620, which greatly saves the working time of the staff and improves the production efficiency.

[0107] During material feeding, the top tray of the first support component 720 is at the set feeding height.

[0108] The corresponding gripping mechanism will move to the top tray at the feeding position 610 to grip the material until the material in the top tray is completely used up. At this time, the empty tray will be transferred away by the empty tray transfer unit, and the first tray support mechanism 700 will move up one tray height so that the top tray in the remaining trays is at the set feeding height to continue feeding.

[0109] The first tray support mechanism 700 sets the first support member 720 in a liftable arrangement. In use, multiple material trays arranged in a stacked manner can be placed on the first support member 720 at one time. After the top tray is used up, the first support member 720 can be raised to continue feeding the next tray. Multiple trays can be fed at one time, which eliminates the need for frequent feeding, reduces the feeding frequency, extends the feeding cycle, and improves feeding efficiency.

[0110] The empty material tray transfer unit operates to transfer and position the top empty material tray to a position above the top material tray of the second support 820.

[0111] Before the empty tray is placed above the multiple stacked trays on the second support 820, the top tray on the second support 820 has already been unloaded. At this point, the empty tray is transferred to continue unloading.

[0112] To ensure that the empty material trays are at the set material release height, the second support component 820 is lowered by one tray height.

[0113] Throughout the production process, the first support 720 continuously moves upward to use up the materials in the multiple trays above it, while the second support 820 continuously moves downward to fill the trays above it with materials.

[0114] In this embodiment, the automatic loading and unloading tray transfer line can control the first support member 720 to move down to the first receiving part 711 when loading the tray. Then, it can connect with the corresponding AGV or trolley equipment through the first lateral moving mechanism to automatically receive and transport the tray. After the tray is transported to the position, the first support member 720 rises to support the multi-layer trays to move upward until the top tray moves to the feeding position 610 so that it can automatically feed the tray. This realizes the automatic loading and feeding of the full-load tray.

[0115] After the full material tray is used up, the empty material tray is directly transferred to the unloading position 620 through the material tray transfer unit for unloading, realizing the automatic unloading of the empty material tray after use;

[0116] After the material is discharged, the material tray is moved down to the second receiving part 811 of the second transverse conveying mechanism 810 by the second support member 820 of the second material tray support mechanism 800. Then, the material tray filled with material is automatically output outward by the second transverse conveying mechanism 810, realizing the automatic unloading of the full material tray after the material is discharged.

[0117] The automatic loading and unloading of full and empty material trays is achieved through the cooperation of the first material tray support mechanism 700, the empty material tray transfer unit, and the second material tray support mechanism 800, thereby improving production efficiency.

[0118] In this embodiment, the automatic loading and unloading tray transfer can also directly transfer the empty tray generated at the feeding position 610 to the unloading position 620 for use. This eliminates the need to set up a corresponding robotic arm to grab the empty tray at the feeding position 610 and to prepare an empty tray for the unloading position 620, which greatly saves the preparation time of the empty tray and greatly improves production efficiency.

[0119] With the liftable first support 720 and second support 820, the material feeding position 610 can automatically rise one tray height after an empty tray is used up to continue feeding. The second tray support mechanism 800 can automatically descend one tray height to continue discharging. This allows for continuous feeding at the material feeding position 610 and continuous provision of empty trays at the discharging position 620, thus extending the tray replacement cycle.

[0120] In some embodiments of this application, the empty material tray transfer unit includes:

[0121] An empty material tray conveyor line 100 is arranged between the first material tray support mechanism 700 and the second material tray support mechanism 800, and is used to convey empty material trays that have been used up at the first material tray support mechanism 700.

[0122] The material tray transfer mechanism is used in conjunction with the empty material tray conveyor line 100 to transfer the empty material tray at the material supply position 610 to the material discharge position 620.

[0123] The material tray transfer mechanism is mainly used to transfer the empty material tray on the first support 720 to the empty material tray conveyor line 100, and then transfer it from the empty material tray conveyor line 100 to the second support 820, so as to realize the transfer of the empty material tray.

[0124] In some embodiments of this application, the first tray support mechanism 700 includes:

[0125] The first frame body 730 includes first side frame members arranged opposite to each other;

[0126] The first back frame member, which is connected to one end of the two first side frame members, and the three of them are arranged to form an installation space.

[0127] At least two first transverse conveying mechanisms 710 are provided, and a first receiving portion 711 is formed between two adjacent first transverse conveying mechanisms 710.

[0128] The first transverse conveying mechanism 710 is located at the bottom of the installation space and includes:

[0129] The first transverse drive motor has a first output shaft, on which two sets of belt pulley assemblies are connected. When the first transverse drive motor rotates, it can drive the two sets of belt pulley assemblies to move, so that the belts of the two sets of belt pulley assemblies move to convey the material tray.

[0130] The first vertical conveying mechanism 740 is connected to the first support member 720 and is used to drive the first support member 720 to move vertically.

[0131] The first vertical conveying mechanism 740 includes: a first vertical drive motor;

[0132] A first vertical belt pulley assembly and a first lead screw nut assembly connected to the first vertical drive motor.

[0133] There are two first vertical synchronous pulleys, with a synchronous belt wound around them.

[0134] The first lead screw and nut assembly includes a first lead screw, a first nut, and a movable plate connected to the first nut.

[0135] One of the first vertical synchronous pulleys is connected to the first vertical drive motor, and the other first vertical synchronous pulley is connected to the first lead screw.

[0136] The first support member 720 is connected to the movable plate. The first support member 720 includes a plurality of first support rods arranged side by side and connected to the movable plate.

[0137] Guide holes are provided on the movable plate, and guide rods are provided on the first frame body 730. The guide rods are arranged vertically and slide up and down along the guide rods through the guide holes when the movable plate moves up and down.

[0138] The first material tray support mechanism 700 has the same structure as the first material tray receiving mechanism, so it will not be described in detail here.

[0139] In some embodiments of this application, the automatic loading and unloading tray transfer line includes:

[0140] A positioning unit is provided at the feeding position 620 for positioning the material tray.

[0141] The tray has two first sides and two second sides perpendicular to the two first sides. The positioning unit includes:

[0142] The first positioning mechanism 910 extends along a direction perpendicular to the first side to position an empty tray between the first positioning mechanism 910 and the tray line base 600 or the second tray support mechanism 800.

[0143] The first positioning mechanism 910 includes at least one first positioning cylinder. The cylinder rod of the first positioning cylinder can extend along the direction perpendicular to the first side of the material tray to press against the material tray from the first side, so that the two first sides of the material tray are clamped and fixed by the first positioning mechanism 910 and the material tray line base 600 or the second material tray support mechanism 800 respectively.

[0144] In some embodiments, a tray positioning plate is provided on the tray line base 600, which is arranged opposite to the first positioning mechanism 910. When the first positioning mechanism 910 is activated, the tray is clamped between the first positioning mechanism 910 and the tray positioning plate.

[0145] In some embodiments, a frame positioning plate may be provided on the second frame of the second tray support mechanism 800, which is fixed on the first side frame member and cooperates with the first positioning mechanism 910 to clamp the tray.

[0146] The second positioning mechanism 920 is retractable and can position an empty tray between the second positioning mechanism 920 and the tray line base 600 or the second tray support mechanism 800 by extending along the second side of the tray perpendicular to it.

[0147] The second positioning mechanism 920 includes at least one second positioning cylinder. When the corresponding cylinder rod extends, it cooperates with the corresponding positioning plate on the same material tray base 600 or the second material tray support mechanism 800 to clamp and position the material tray.

[0148] By cooperating with the first positioning mechanism 910 and the second positioning mechanism 920, the empty material tray placed at the material feeding position 620 can be positioned so that the material can be accurately placed in place during feeding.

[0149] The third detection component 950 includes a pair of photoelectric sensors, which can be used to detect whether the second feeding mechanism has picked up the tray. After the second feeding mechanism picks up the tray and rises to a certain distance, it can be detected by the third detection component 950.

[0150] The first material handling unit 200 is mainly used for picking up and placing materials;

[0151] 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 610 to the empty material tray conveying line 100.

[0152] The first moving mechanism is mainly used to drive the first material conveying unit 200 to move.

[0153] By moving along the first direction, it can drive the first material conveying unit 200 to move between the material supply position 610 and the empty material tray conveyor line 100.

[0154] 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.

[0155] In some embodiments of this application, the second material conveying mechanism includes:

[0156] The second material handling unit 400 is used to grab materials.

[0157] 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.

[0158] 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 620 and the empty material tray conveying line 100.

[0159] By moving the second operating unit along the height direction, the corresponding material tray picking and placing actions can be performed.

[0160] By rotating the second material conveying unit 400, 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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 620 is the first material tray, the second material conveying unit 400 can directly move and place 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.
