Description

Technical Field

[0001] The utility model relates to a stacker, in particular to a lifting stacker, belonging to the technical field of logistics packaging. Background Art

[0002] The stacking of similar products is generally realized through a palletizing device. When using the palletizing device, the load-bearing capacity of its material transfer mechanism should be considered emphatically. Specifically, it is whether the material transfer mechanism itself can stably drive the product to move. After retrieval, in a tank body precise palletizing device disclosed in the patent with the number "CN213325662U", its material transfer frame has a reinforcing frame for improving its own stability. Similarly, the applicant has also designed a lifting stacker and filed the following application. Content of the Utility Model

[0003] Aiming at the deficiencies of the above-mentioned prior art, the utility model provides a lifting stacker.

[0004] To achieve the above object, the technical solution adopted by the utility model is: a lifting stacker, including a top beam and a material transfer mechanism. The bearing frame can slide back and forth on the top beam through the drive of a lead screw. A support plate arranged thereon is provided with a lifting cylinder for connecting the material transfer mechanism. When the bearing frame drives the material transfer mechanism to translate to a specified position, the up and down displacement of the material transfer mechanism can be used to lift or put down materials.

[0005] Preferably, a guide sleeve is further fixed on the support plate of the bearing frame, and the material transfer mechanism has a guide rod slidably connected with the guide sleeve.

[0006] Preferably, a stop head that can abut against the guide sleeve is formed at the end of the guide rod.

[0007] Preferably, the material transfer mechanism has an adsorption assembly. The frame of the adsorption assembly is fixed to the cylinder shaft of the lifting cylinder, and a plurality of suction cups are elastically installed at equal intervals below the frame.

[0008] Preferably, two lead screws are arranged in parallel on the top beam. A threaded block arranged on the lead screw is fixed to the bearing frame. When the lead screw rotates due to the drive of a transmission component, the threaded block can drive the bearing frame to slide back and forth.

[0009] Preferably, the transmission component includes a gear seat fixed to the top beam. A main gear and two sub-gears meshing with it are installed in the gear seat. The main gear can be driven by a lead screw motor to drive the two lead screws to rotate synchronously through the sub-gears.

[0010] The utility model has at least the following advantages:

[0011] 1. By means of the bearing frame sharing the pressure of the material transfer mechanism on the top beam, the smoothness of the translation of the material transfer mechanism is improved;

[0012] 2. The guide bushing and guide rod can linearly guide the lifting process of the material transfer mechanism, and at the same time can prevent the material transfer mechanism from sagging and deforming.

[0013] 3. The material transfer mechanism is driven by a lead screw to translate, and the sliding process is more accurate and stable. Description of the Drawings

Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] As Figures 1-4 shown: A lifting stacker includes a top beam 1. A bearing frame 2 is slidably installed on the top beam 1 by means of a slider - rail cooperation, and three support plates 201 are fixedly installed thereon. And an elevating cylinder 3 is fixed on each support plate 201. The elevating cylinder 3 is used to drive the material transfer mechanism 4 to move up and down to lift or place materials at a specified position.

[0021] Specifically, the above - mentioned material transfer mechanism 4 realizes the lifting and placing of materials through the adsorption component 401; as Figure 2As shown in the figure, the adsorption assembly 401 has a frame body 411. The frame body 411 is fixed to the cylinder shaft of the lifting cylinder 3 to realize the overall lifting of the adsorption assembly 401. A number of support rods 421 are installed below the frame body 411 at equal intervals. Each support rod 421 is elastically provided with 3 suction cups 441 through a foot rod 431 (the adsorption assembly 401 can also be replaced with a clamping assembly of the existing design).

[0022] Specifically, in order to avoid the shaking of the material transfer mechanism 4 during the lifting process, guide sleeves 202 are further fixed to the support plates 201 on both sides of the above-mentioned bearing frame 2, and guide rods 402 with stop heads 412 formed at the ends are correspondingly installed on the frame body 411. While the guide rods 402 are in sliding fit with the guide sleeves 202, they can prevent themselves from detaching from the guide sleeves 202 through the stop heads 412.

[0023] Furthermore, the sliding of the above-mentioned bearing frame 2 is realized through a lead screw 5 and a lead screw motor 501. Among them, there are two lead screws 5, and the two are installed in parallel on the top beam 1. The reason for adopting this method is to avoid the above-mentioned lifting cylinder 3 in the central position. Threaded blocks 502 are respectively installed on the two lead screws 5, and the bearing frame 2 is fixed to the threaded blocks 502. Since the two lead screws 5 can rotate synchronously under the drive of the lead screw motor 501, the threaded blocks 502 will drive the bearing frame 2 to move forward and backward through thread engagement.

[0024] Specifically, a transmission assembly 6 including a main gear 601 and two sub-gears 602 is fixed to the above-mentioned top beam 1. The main gear 601 and the two sub-gears 602 are both installed in a gear seat 603. Among them, the main gear 601 is connected to the lead screw motor 501, and the two sub-gears 602 are respectively connected to a lead screw 5. Since the two sub-gears 602 are both directly meshed and driven with the main gear 601, the lead screw motor 601 can drive the two lead screws 5 to rotate synchronously in the same direction.

[0025] It can be understood that the present invention is described through some embodiments.
