Description

Technical Field

[0001] The utility model relates to the technical field of stacking equipment, and particularly relates to a stacker with precise positioning. Background Art

[0002] Traditional stackers are usually used in automated warehousing systems, and their main function is to stack and pick up goods efficiently in the warehouse. However, existing stackers have some limitations in certain aspects, especially in terms of precise positioning and operational flexibility, and there is still room for improvement. Common stackers on the market currently have some limitations in the precise positioning ability of goods. Due to the limitations of the design and control system, traditional stackers often have difficulty achieving precise positioning of goods in scenarios with limited height or dense stacking, which may lead to errors and low efficiency during the stacking process. During the stacking or picking process, if the goods themselves are unstable or stacked poorly, it may cause the stacker to be unable to accurately position when grasping or placing the goods, thereby affecting the smooth progress of the operation.

[0003] Therefore, this application has developed a stacker with precise positioning to solve the problems existing in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a stacker with precise positioning to solve the problems of insufficient stability of goods stacking caused by inaccurate positioning and possible tipping during the stacking and picking processes in the prior art.

[0005] The technical solution of the utility model is: a stacker with precise positioning, comprising:

[0006] A lifting roller bed for lifting goods to different heights. The lifting roller bed includes a lifting plate and a lifting driving device. A clamping and positioning device is provided on the lifting plate. The clamping and positioning device includes a fixing member, a driving mechanism I, an adjusting rod, and a pair of swing arms. The fixing member is fixedly connected to the lifting plate. A pair of swing arms are respectively hinged on the fixing member. A limiting portion is provided at one end of the swing arm away from the hinged position. A guiding groove is provided on each of the pair of swing arms. The adjusting rod passes through the guiding groove and is connected to the connecting end of the driving mechanism. The fixed end of the driving mechanism I is fixedly connected to the lifting plate; when the adjusting rod rotates, the pair of swing arms both rotate around the hinged portion, and the two limiting portions approach or move away from each other;

[0030] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:

[0031] Such as Figures 1 - 4As shown in the figure, a stacker with precise positioning includes a lifting roller bed 1, a clamping and positioning device 2, a pair of first swing arm mechanisms 3, and a pair of second swing arm mechanisms 4. The lifting roller bed 1 includes a lifting plate 11. The goods are placed on the lifting plate 11, and the lifting plate 11 is controlled by the lifting roller bed 1 to move up and down to adjust the height of the goods. The clamping and positioning device 2 includes a fixing member 21, a first driving mechanism 22, an adjusting rod 23, and a pair of swing arms 26. The fixing member 21 is fixed on the lifting plate 11, and two swing arms 26 are hinged on the fixing member 21. The swing arms 26 are provided with guide grooves 25. The adjusting rod 23 is arranged in the guide grooves 25, and the adjusting rod 23 is connected to the first driving mechanism 22. When the first driving mechanism 22 rotates, it drives the adjusting rod 23 to rotate. Since the adjusting rod 23 is arranged in the guide grooves 25, the adjusting rod 23 can only move back and forth in the guide grooves 25. The rotation of the adjusting rod 23 will cause the swing arms 26 to rotate around the hinge part, so that the two limiting parts 24 approach or move away from the support rod 8. When the two limiting parts 24 approach the support rod 8, the goods are restricted to a fixed position, so that the goods can be positioned, and it also prevents the goods from shifting during the ascending and descending processes of the lifting roller bed 1, affecting the stacking and picking of the goods. Among them, the first swing arm mechanism 3 and the second swing arm mechanism 4 are respectively located on both sides of the goods and are corresponding in position. During the operation of the stacker, the third driving mechanism 32 and the rotation adjusting mechanism 42 respectively control the rotation of the first support arm 31 and the second support arm 41. By horizontally rotating the first support arm 31 and the second support arm 41, the position of the goods can be flexibly adjusted, so that it can be accurately stacked, facilitating the storage and retrieval of the goods.

[0032] Further, when the adjusting rod 23 is located at the center of the guide groove 25, the two limiting parts 24 are closest to each other. At this time, both of the two limiting parts 24 are abutted against the support rod 8, preventing the insufficient moving distance of the limiting parts 24, resulting in the inability to position and limit the goods. When the adjusting rod 23 is located at both ends of the guide groove 25, the two limiting parts 24 are farthest from each other. At this time, the height of the two limiting parts 24 is lower than the height of the support rod 8, preventing the higher height of the limiting parts 24 from blocking the movement of the goods when the goods move on the rollers 51.

[0033] In this embodiment, as Figures 4 - 6 shown, the lifting roller bed 1 is further provided with a first guiding part 5 and a second guiding part 6. The first guiding part 5 includes two rollers 51 and a connecting rod 52. The two rollers 51 are connected by the connecting rod 52. The first guiding part 5 is arranged along the movement direction of the goods. Adjacent two first guiding parts 5 are connected by a belt. One of the first guiding parts 5 is connected to the second driving mechanism 7. Driven by the second driving mechanism 7, multiple first guiding parts 5 rotate simultaneously, enabling the goods to move on the first guiding parts 5 and accurately move along a predetermined path, ensuring that the goods can be precisely placed at a designated position and improving the storage and retrieval efficiency.

[0034] As Figure 6As shown, a plurality of second guiding parts 6 are respectively arranged on both sides of the goods and closely attached to the outer side surface of the side rod 9. The second guiding part 6 being closely attached to the outer side surface of the side rod 9 can ensure that the stacker always travels along a predetermined track or path during movement, preventing deviation or offset. Through the precise guiding of the second guiding part 6, the stacker can accurately reach the designated position, realizing the precise storage and retrieval of goods. The second guiding part 6 can also effectively reduce the vibration generated during the movement of the stacker, making the equipment operation more stable, while being able to reduce the wear caused by friction and prevent the goods from tipping over. When the stacker moves at high speed or bears a large load, the second guiding part 6 can provide additional support and stability to ensure that the equipment does not tip over due to loss of balance.

[0035] Furthermore, the edge of the contact surface between the roller 51 and the goods side rod 9 bulges upward to form a groove, and the side rod 9 is located within the groove. The roller 51 provides stable support for the goods, ensuring that the goods can remain stable during the operation of the stacker and preventing shaking or tilting caused by unstable center of gravity. The higher edge of the contact surface enables the side rod 9 to only move on the roller 51 and will not be misaligned or deviate from the running track during movement. At the same time, the higher edge can cooperate with the clamping and positioning mechanism to position the goods in another direction, further improving the accuracy and stability of stacking.

[0036] Among them, the shape of the second guiding part 6 is but not limited to spherical, cylindrical, or frustum-shaped. Specifically, the second guiding part 6 is frustum-shaped, and the outer side surface of the bottom of the second guiding part 6 is in fit with the outer side surface of the side rod 9. The second guiding part 6 being frustum-shaped can fit more closely to the track or preset path, thereby providing better guiding performance, helping to reduce the offset and shaking of the goods during movement. The frustum-shaped design increases the contact area with the side rod 9, thereby improving the stability of the goods during movement.

[0037] Furthermore, as Figures 7 - 8As shown in the figure, the rotation adjustment mechanism 42 includes a driving mechanism four 421, a rotating plate 422, and a connecting rod 423. The rotating plate 422 is connected to the connecting end of the driving mechanism four 421. One ends of the two connecting rods 423 are respectively hinged to both ends of the rotating plate 422, and the other ends of the two connecting rods 423 are respectively hinged to the corresponding support arms two 41. When the driving mechanism four 421 moves, it drives the rotating plate 422 to rotate. When the rotating plate 422 rotates, the connecting rods 423 at both ends move along with the rotation of the rotating plate 422. Among them, the two connecting rods 423 have the same length, and the driving mechanism four 421 is located at the center of the two second swing arm mechanisms 4, which can ensure that when the driving mechanism four 421 moves, the two connecting rods 423 approach or move away from each other simultaneously. The two connecting rods 423 respectively drive the corresponding support arms to rotate, so that the two support arms move synchronously in two directions, thus ensuring the synchronous coordination of the movement, and preventing the two support arms from having errors due to insufficient synchronous coordination, which may cause the goods on one side to shift or tip over, resulting in stacking failure or even damage to the goods.

[0038] The implementation principle of this embodiment:

[0039] When stacking goods, the first swing arm mechanism 3 and the second swing arm mechanism 4 lift the goods through the support arm one 31 and the support arm two 41. The lifting drive device 12 drives the lifting plate 11 to move below the goods. The first swing arm mechanism 3 and the second swing arm mechanism 4 respectively control the rotation of the support arm one 31 and the support arm two 41 to adjust the position of the goods to match the clamping and positioning device 2 and the roller 51 below. Among them, the side rod 9 of the goods falls on the roller 51 and is between the two side walls, and the support rod 8 is between the two limiting parts 24. The driving mechanism one 22 moves to drive the adjusting rod 23 to move in the guiding groove 25, so that the two limiting parts 24 approach the support rod 8 and clamp the support rod 8, positioning the goods in the direction parallel to the movement. At the same time, the roller 51 and the second guiding part 6 limit the goods in the direction perpendicular to the movement, realizing the precise positioning and stability of the goods. During the processes of stacking, picking up goods, rising, and falling, the goods are limited in two mutually perpendicular directions, and the sliding and tilting of the goods will not occur.
