Description

Technical Field

[0001] This invention relates to the field of automatic material palletizing telescopic forks, and more particularly to an automatic material palletizing telescopic fork. Background Technology

[0002] Automatic palletizers are high-tech products that integrate electromechanical systems. Medium and low-level palletizers can meet the production needs of medium and low output. The rail-guided stacker cranes used by palletizers are usually designed with a loading platform and equipped with a set of forks. They can complete the palletizing of various products such as goods according to the required grouping method and number of layers.

[0003] When existing automatic palletizing machines are palletizing, the fork platform needs to be retracted after the goods are stacked. During the retraction process, the goods are prone to displacement, resulting in palletizing deviation and affecting subsequent stacking. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in existing designs where, during palletizing, the forklift platform needs to be retracted after the goods are stacked, and during the retraction process, the goods are easily displaced, resulting in palletizing deviations and affecting subsequent stacking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic material palletizing telescopic fork includes a shelf, with a palletizing device movably mounted at the front end of the shelf; The palletizing device includes a base, with rollers at the bottom of the base and a lifting frame fixedly connected to the top of the base. A palletizing mechanism is slidably installed inside the lifting frame, and a lifting mechanism is fixedly installed on the top of the lifting frame. The lifting mechanism is used for the vertical lifting and lowering movement of the palletizing mechanism. The palletizing mechanism includes a placement frame, which is fixedly connected to the moving end of the lifting mechanism. A limiting mechanism is fixedly connected to the top of the placement frame. A drive assembly is fixedly connected to the inner walls on both sides of the placement frame. A fork platform is slidably installed inside the placement frame and is fixedly connected to the moving end of the drive assembly. An auxiliary support assembly is provided between the fork platform and the bottom of the placement frame. An auxiliary discharge mechanism is fixedly connected to both sides of the top of the fork platform.

[0006] Preferably, the lifting mechanism includes a dual-axis motor, which is fixedly connected to the top of the lifting frame. A connecting shaft is fixedly connected to each of the two output ends of the dual-axis motor. A brake is provided on each connecting shaft. A pulley is interference-fitted on the end of each connecting shaft away from the dual-axis motor. A wire rope is installed on the pulley. A counterweight is fixedly connected to one end of the wire rope, and the other end of the wire rope is fixedly connected to the stacking mechanism.

[0007] Preferably, the forklift platform is provided with a mounting slot, and multiple pulleys are rotatably installed inside the mounting slot to facilitate the unloading of goods. A fixing plate is fixedly connected to the top of the forklift platform at the end away from the mounting slot, and multiple auxiliary wheels are rotatably installed on the outside of the fixing plate. The auxiliary wheels are all slidably installed on the top of the placement frame to improve the stability of the forklift platform when it moves.

[0008] Preferably, the auxiliary support assembly includes a first hinge seat, which is fixedly connected to the placement frame. A first hydraulic cylinder is rotatably mounted on the first hinge seat, and a second hinge seat is rotatably mounted on the end of the first hydraulic cylinder away from the first hinge seat. The second hinge seat is fixedly connected to the bottom of the fork platform. When the fork platform moves, the first hydraulic cylinder works synchronously with the drive assembly, which can provide some power and provide a certain support force when the fork platform is detached from the placement frame, thereby further improving the stability of the fork platform when it moves.

[0009] Preferably, the limiting mechanism includes two cylinders, which are respectively fixedly connected to the top of one end of the placement frame. A top plate is fixedly connected between the tops of the two cylinders, and a side plate is fixedly connected to the bottom of the top plate. When discharging, the cylinders work to limit the goods to the top of one end of the stacking device, and the auxiliary discharging mechanism and motor facilitate the discharging.

[0010] Preferably, the auxiliary discharge mechanism includes a track fixedly connected to the top of the mounting groove. A ball screw is rotatably mounted inside the track. A motor is fixedly connected to the end of the ball screw away from the shelf. The motor is fixedly connected to the fork platform. A slider is fixedly connected to the moving end of the ball screw. A second hydraulic cylinder is fixedly connected to one side of the slider. A clamping plate is fixedly connected to the telescopic end of the second hydraulic cylinder. During discharge, the motor operates, and the output end of the motor rotates, driving the ball screw to rotate. The rotation of the ball screw drives the slider to move, so that the slider is located at the end away from the shelf. At this time, the second hydraulic cylinder operates, causing the clamping plates at both ends to move inward to clamp the goods on both sides. The drive component operates to move the fork platform backward. Due to the limitation of the top plate and side plate, the goods on the fork platform are in a relatively stationary state, which can stably stack the goods and avoid the goods from shifting when the fork platform moves backward, thus improving the stacking stability.

[0011] Compared with the prior art, the present invention provides an automatic material palletizing telescopic fork, which has the following beneficial effects: 1. The present invention, through the setting of lifting mechanism and palletizing mechanism, places the goods to be palletized on the top of the fork platform. The dual-axis motor works to move the palletizing mechanism to a suitable position. Then the drive component works to move the fork platform to the top of the goods inside the shelf, which facilitates the palletizing operation of goods of different heights and depths. 2. This invention utilizes a combination of a palletizing mechanism, a limiting mechanism, and an auxiliary unloading mechanism. When the motor operates, the slider is positioned away from the shelf. At this time, the second hydraulic cylinder operates, causing the clamping plates at both ends to move inward and clamp the goods on both sides. The drive assembly operates to move the fork platform backward. Due to the limiting effect of the top plate and side plates, the goods on the fork platform are in a relatively stationary state, allowing for stable palletizing. This avoids the fork platform retracting and causing the goods to shift, thus improving palletizing stability. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0015] Please see Figure 1-3 An automatic material palletizing telescopic fork includes a shelf 1, with a palletizing device 2 movably installed at the front end of the shelf 1; The palletizing device 2 includes a base 3, with rollers 5 at the bottom of the base 3 and a lifting frame 4 fixedly connected to the top of the base 3. A palletizing mechanism 7 is slidably installed inside the lifting frame 4, and a lifting mechanism 6 is fixedly installed on the top of the lifting frame 4. The lifting mechanism 6 is used for the vertical movement of the palletizing mechanism 7. The palletizing mechanism 7 includes a placement frame 701, which is fixedly connected to the moving end of the lifting mechanism 6. A limiting mechanism 8 is fixedly connected to the top of the placement frame 701. A drive assembly 702 is fixedly connected to the inner walls on both sides of the placement frame 701. A fork platform 703 is slidably installed inside the placement frame 701. The fork platform 703 is fixedly connected to the moving end of the drive assembly 702. An auxiliary support assembly 704 is provided between the fork platform 703 and the bottom of the placement frame 701. An auxiliary discharge mechanism 9 is fixedly connected to both sides of the top of the fork platform 703. The lifting mechanism 6 includes a dual-axis motor 601, which is fixedly connected to the top of the lifting frame 4. Both output ends of the dual-axis motor 601 are fixedly connected to a connecting shaft 602, and each connecting shaft 602 is equipped with a brake 603. Each end of the connecting shaft 602 away from the dual-axis motor 601 is fitted with a pulley 604 with an interference fit. A wire rope 605 is installed on the pulley 604. One end of the wire rope 605 is fixedly connected to a counterweight 606, and the other end of the wire rope 605 is fixedly connected to the stacking mechanism 7.

[0016] In use, the goods to be stacked are placed on top of the forklift platform 703. The dual-axis motor 601 operates, and the output end of the dual-axis motor 601 rotates to drive the connecting shaft 602. The rotation of the connecting shaft 602 drives the steel wire rope 605 on the pulley 604 to move up and down, so that the stacking mechanism 7 moves up to a suitable position. Then the drive component 702 operates to move the forklift platform 703 to the top of the goods inside the shelf 1, which facilitates the stacking operation of goods of different heights and depths. Example 2:

[0017] Please see Figure 3-6 The difference from Example 1 is that: The forklift platform 703 is provided with a mounting slot 7031. Multiple pulleys 7032 are rotatably installed inside the mounting slot 7031 to facilitate the unloading of goods. A fixing plate 7033 is fixedly connected to the top of the end of the forklift platform 703 away from the mounting slot 7031. Multiple auxiliary wheels 7034 are rotatably installed on the outside of the fixing plate 7033. The auxiliary wheels 7034 are all slidably installed on the top of the placement frame 701 to improve the stability of the forklift platform 703 when it moves. The auxiliary support assembly 704 includes a first hinge seat 7041, which is fixedly connected to the placement frame 701. A first hydraulic cylinder 7042 is rotatably mounted on the first hinge seat 7041. A second hinge seat 7043 is rotatably mounted on the end of the first hydraulic cylinder 7042 away from the first hinge seat 7041. The second hinge seat 7043 is fixedly connected to the bottom of the fork platform 703. When the fork platform 703 moves, the first hydraulic cylinder 7042 works synchronously with the drive assembly 702, which can provide some power and provide a certain support force when the fork platform 703 is separated from the placement frame 701, thereby further improving the stability of the fork platform 703 when it moves. The limiting mechanism 8 includes two cylinders 801, which are fixedly connected to the top of one end of the placement frame 701. A top plate 802 is fixedly connected between the tops of the two cylinders 801, and a side plate 803 is fixedly connected to the bottom of the top plate 802. When discharging, the cylinders 801 work to limit the goods to the top of one end of the stacking device 2, and then cooperate with the auxiliary discharging mechanism 9 and the motor 903 to facilitate discharging. The auxiliary discharge mechanism 9 includes a track 901, which is fixedly connected to the top of the mounting slot 7031. A ball screw 902 is rotatably mounted inside the track 901. A motor 903 is fixedly connected to the end of the ball screw 902 away from the shelf 1. The motor 903 is fixedly connected to the fork platform 703. A slider 904 is fixedly connected to the moving end of the ball screw 902. A second hydraulic cylinder 905 is fixedly connected to one side of the slider 904. A clamping plate 906 is fixedly connected to the telescopic end of the second hydraulic cylinder 905. During discharge, the motor 903 operates and outputs... The rotation of the end causes the ball screw 902 to rotate, which in turn causes the slider 904 to move, positioning the slider 904 at the end furthest from the shelf 1. At this time, the second hydraulic cylinder 905 operates, causing the clamping plates 906 at both ends to move inward and clamp the goods on both sides. The drive assembly 702 operates, moving the fork platform 703 backward. Due to the limiting effect of the top plate 802 and the side plate 803, the goods on the fork platform 703 are in a relatively stationary state, allowing for stable stacking of goods. This avoids the fork platform 703 retracting and causing the goods to shift, thus improving stacking stability.

[0018] Working principle: In use, the goods to be palletized are placed on top of the forklift platform 703. The dual-axis motor 601 operates, and its output rotates to drive the connecting shaft 602. The connecting shaft 602 rotates, causing the steel wire rope 605 on the pulley 604 to move up and down, thus moving the palletizing mechanism 7 to a suitable position. Then, the drive assembly 702 operates, moving the forklift platform 703 to the top of the goods inside the rack 1. At this time, the motor 903 operates, and its output rotates to drive the ball screw 902 to rotate. The rotation of the lead screw 902 drives the slider 904 to move, so that the slider 904 is located at the end away from the shelf 1. At this time, the second hydraulic cylinder 905 works, causing the clamping plates 906 at both ends to move inward to clamp the goods on both sides. The drive assembly 702 works to move the fork platform 703 backward. Due to the limiting of the top plate 802 and the side plate 803, the goods on the fork platform 703 are in a relatively stationary state, which can stably stack the goods and avoid the fork platform 703 moving backward and causing the goods to shift, thus improving the stacking stability.
