Description

Technical Field

[0001] The utility model belongs to the field of mechanical manufacturing, and in particular relates to a material handling device. Background Art

[0002] Material handling devices are devices used to move and transport materials in industrial and warehousing environments, which can improve handling efficiency and reduce manual operations.

[0003] After the existing material handling devices complete material loading, it is necessary to limit the materials to prevent the materials from escaping from the handling devices during movement. In order to ensure the firmness of the limit, the existing material handling devices are often provided with limit structures in different directions, but the limit structures in each direction are all independently provided without linkage. Therefore, after the material loading is completed, each limit structure needs to be manually adjusted to limit the materials in the corresponding direction, which is cumbersome to operate. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a material handling device, aiming to solve the problem that the limiting structure on the existing material handling device has no linkage, resulting in complicated limiting operation.

[0005] The embodiment of the utility model is implemented in this way, providing a material handling device, the device comprising:

[0006] A base, wherein a plurality of rollers are arranged at the bottom of the base;

[0007] A placing plate, arranged on the base, for placing materials;

[0008] A first limiting mechanism, disposed on the placement plate, for limiting the material in a first direction;

[0009] The second limiting mechanism is arranged on the placing plate, and the second limiting mechanism is connected to the first limiting mechanism. When the material is placed on the placing plate, the first limiting mechanism is activated to make the first limiting mechanism form resistance to the material in the first direction. At the same time, the movement of the first limiting mechanism drives the movement of the second limiting mechanism, so that the second limiting mechanism moves to a position that limits the movement of the material in the second direction, so as to limit the material in the second direction.

[0010] Preferably, the first limiting mechanism includes two sets of driving components and a flexible limiting belt, the flexible limiting belt is arranged between the two sets of driving components, and the two sets of driving components jointly drive the flexible limiting belt to move so that the flexible limiting belt limits the material in the first direction.

[0011] Preferably, the first direction is a vertical direction, and each set of driving components comprises:

[0012] A driving motor is arranged on a placement plate, and a first gear is provided on the output end of the driving motor;

[0013] A first bracket is arranged on the placement plate, and a slide rail extending in a first direction is provided on the first bracket;

[0014] A lead screw is rotatably connected to the placement plate, the lead screw extends in the first direction, and a second gear is sleeved on the lead screw;

[0015] A moving plate is in threaded connection with the lead screw, and a groove matching with the slide rail is provided on the moving plate, and the slide rail is embedded in the groove, so that when the lead screw is driven to rotate, the slide rail forms a limit on the groove in a direction perpendicular to the first direction, so that the moving plate does not rotate with the lead screw but rotates relatively to the lead screw, and then moves in the first direction;

[0016] Furthermore, one end of a flexible limiting belt is connected to the moving plate of a set of driving components, and the other end is connected to the moving plate of another set of driving components. The two sets of driving components move the moving plate in the first direction at the same time, so that the flexible limiting belt moves in the first direction to abut against the material.

[0017] Preferably, two first limiting mechanisms are arranged adjacent to each other on the placement plate, and the driving motor is a double-shaft motor; one output end of each driving motor provides power for the driving components of one first limiting mechanism, and the other output end provides power for the driving components of the other first limiting mechanism.

[0018] Preferably, the second direction is the horizontal direction, there are two second limiting mechanisms, and each second limiting mechanism is correspondingly arranged with a first limiting mechanism; the second limiting mechanism includes two sets of fence components, and each set of fence components is arranged with a set of driving components corresponding to the first limiting mechanism; each set of fence components includes:

[0021] A second shaft rod is fixed on the moving plate in the corresponding driving components along the second direction;

[0022] The sliding rod has slot holes formed along the entire rod body. The sliding rod includes a first bent section and a second bent section. The bending angle of the first bent section is 90 degrees, and the bending angle of the second bent section is less than 90 degrees. The first shaft rod is embedded in a partial slot hole of the first bent section, and the second shaft rod is embedded in a partial slot hole of the second bent section. When the corresponding moving plate is driven to drive the flexible limiting belt towards the material, the second shaft rod moves along with the moving plate, thereby forming a resisting force against the slot hole wall of the second bent section. This resisting force drives the sliding rod to slide under the limitation of the first shaft rod and the second shaft rod, causing the first shaft rod to move to a position that restricts the movement of the material in the second direction, so as to form a limit on the material in the second direction.

[0023] Preferably, the second bracket is a fence bracket, and each second bracket is arranged at a position that restricts the movement of the material in the horizontal direction perpendicular to the second direction. Each second bracket is also provided with a plurality of rollers.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1 As shown, a material handling device provided by an embodiment of the utility model comprises:

[0036] A base 1, a plurality of rollers 11 are provided at the bottom of the base 1;

[0037] A placing plate 2 is arranged on the base 1 and is used for placing materials;

[0038] A first limiting mechanism 3, arranged on the placement plate 2, for limiting the material in a first direction;

[0039] The second limiting mechanism 4 is arranged on the placing plate 2, and the second limiting mechanism 4 is connected to the first limiting mechanism 3. When the material is placed on the placing plate 2, the first limiting mechanism 3 is started, so that the first limiting mechanism 3 forms a resistance to the material in the first direction. At the same time, the movement of the first limiting mechanism 3 drives the second limiting mechanism 4 to move, so that the second limiting mechanism 4 moves to a position that limits the movement of the material in the second direction, so as to limit the material in the second direction.

[0040] In the present application, the roller 11 may be a universal wheel provided at the bottom of the base 1. After the material is placed on the placing plate 2 and the limiting mechanism is adjusted, the material handling device makes the roller 11 rotate under the action of an external force, and then makes the material handling device move to achieve handling. In the present application, the limiting mechanism is adjusted after the material is placed on the placing plate, so as to avoid blocking the material during feeding, ensure smooth feeding, and after the feeding is completed, by adjusting the first limiting mechanism 3, the second limiting mechanism 4 can be coordinated to limit the material, without the need for separate adjustment of the two, greatly simplifying the adjustment process, with simple operation and improved efficiency of limit adjustment.

[0041] As a preferred embodiment, the first limiting mechanism 3 includes two groups of driving components and a flexible limiting belt 31. The flexible limiting belt 31 is arranged between the two groups of driving components, and the two groups of driving components jointly drive the flexible limiting belt 31 to move, so that the flexible limiting belt 31 limits the material in the first direction.

[0042] In this embodiment, the first direction is the vertical direction. The flexible limiting belt 31 may be an elastic belt. The two groups of driving components jointly drive the flexible limiting belt 31 to move vertically downward from top to bottom until it touches the material. When it touches the material, it has a better fit with the material, and the taut belt can form a reaction force on the material, having a better limiting effect.

[0043] As Figures 2 - 4 shown, as a preferred embodiment, the first direction is the vertical direction, and each group of driving components includes:

[0044] A driving motor 32, arranged on the placing plate 2, and a first gear 321 is provided on the output end of the driving motor 32;

[0045] A first bracket 33, arranged on the placing plate 2, and a slide rail 331 extending in the first direction is provided on the first bracket 33;

[0046] A lead screw 34, rotatably connected to the placing plate 2, the lead screw 34 extends in the first direction, and a second gear 341 is sleeved on the lead screw 34;

[0047] A moving plate 35, threadedly connected to the lead screw 34, and a groove 351 matching the slide rail 331 is provided on the moving plate 35, and the slide rail 331 is embedded in the groove 351, so that when the lead screw 34 is driven to rotate, the slide rail 331 forms a limit on the groove 351 in the direction perpendicular to the first direction, so that the moving plate 35 does not rotate with the lead screw 34 but rotates relative to the lead screw 34, and then moves in the first direction;

[0048] Furthermore, one end of the flexible limiting belt 31 is connected to the moving plate 35 of one set of driving components, and the other end is connected to the moving plate 35 of another set of driving components. The two sets of driving components simultaneously move the moving plate 35 in the first direction, thereby moving the flexible limiting belt 31 in the first direction to contact with the material.

[0049] In this embodiment, a stopper is provided on the top of the first bracket 33 to prevent the movable plate 35 from falling off the screw rod 34 when the movable plate 35 moves relative to the screw rod 34; a groove 351 is also provided on the first bracket 33, and the slide rail 331 is arranged in the groove 351 of the first bracket 33. The slide rail 331 is a T-shaped slide rail 331, and the groove 351 on the movable plate 35 is also a T-shaped groove 351, so that the T-shaped groove 351 and the T-shaped slide rail 331 are mutually engaged, and have a better embedding effect; due to the horizontal limiting effect of the slide rail 331 on the groove 351 on the movable plate 35, when the screw rod 34 rotates, the movable plate 35 will not rotate therewith, but will only move along the extension direction of the slide rail 331, thereby realizing the movement of the flexible limiting belt 31 in the vertical direction.

[0050] As a preferred embodiment, two first limiting mechanisms 3 are adjacently arranged on the placement plate 2, and the drive motor 32 is a dual-axis motor; one output end of each drive motor 32 provides power for a drive component of a first limiting mechanism 3, and the other output end provides power for a drive component of another first limiting mechanism 3.

[0051] In this embodiment, by providing a dual-axis motor, the two first limiting mechanisms 3 can share a motor, thereby reducing the installation of the drive motor 32 and ensuring synchronization when adjusting the two first limiting mechanisms 3.

[0052] like Figures 5 - 6 As shown, as a preferred embodiment, the second direction is the horizontal direction, there are two second limiting mechanisms 4, and each second limiting mechanism 4 is arranged corresponding to a first limiting mechanism 3; the second limiting mechanism 4 includes two groups of fence components, each group of fence components is arranged with a group of driving components corresponding to the first limiting mechanism 3; each group of fence components includes:

[0053] A second bracket 41 is arranged on the placement plate 2;

[0054] A first shaft 42, fixed on the second bracket 41 along a second direction;

[0055] A second shaft 43 is fixed on the moving plate 35 in the corresponding driving assembly along a second direction;

[0056] A sliding rod 44, wherein a slot is provided along the entire rod body of the sliding rod 44, and the sliding rod 44 comprises a first bending section 441 and a second bending section, wherein the bending angle of the first bending section 441 is 90 degrees, and the bending angle of the second bending section is less than 90 degrees; the first shaft rod 42 is embedded in a partial slot hole of the first bending section 441, and the second shaft rod 43 is embedded in a partial slot hole of the second bending section, and when the corresponding moving plate 35 is driven to drive the flexible limiting belt 31 to move toward the material, the second shaft rod 43 moves with the moving plate 35, thereby forming a resistance force on the slot hole wall of the second bending section, and the resistance force drives the sliding rod 44 to slide under the limitation of the first shaft rod 42 and the second shaft rod 43, so that the first shaft rod 42 moves to a position that limits the movement of the material in the second direction, so as to form a limitation on the material in the second direction.

[0057] In this embodiment, the sliding rod 44 is vertically arranged, the first bending section 441 is at the lower end of the sliding rod 44, and the second bending section is at the upper end of the sliding rod 44. The bending angle of the first bending section 441 is 90 degrees, so that the first bending section 441 is perpendicular to the middle section of the sliding rod 44. Under the limitation of the first shaft rod 42, the sliding rod 44 can only slide in the horizontal direction (a direction perpendicular to the second reverse direction). The bending angle of the second bending section is less than 90 degrees, so that the second bending section is inclined relative to the middle section of the sliding rod 44. When the movable plate 35 moves downward, the second shaft rod 43 forms a force on the slot wall at the second bending section, and the horizontal component of the force pushes the sliding rod 44 to slide in the horizontal direction. After the sliding is completed, the first bending section 441 forms an interception effect on the material in the second direction, that is, it forms a limitation on the material in the second direction.

[0058] As a preferred embodiment, the second bracket 41 is a fence bracket, and each second bracket 41 is arranged at a position to limit the movement of the material in a horizontal direction perpendicular to the second direction; each second bracket 41 is also provided with a plurality of rollers 411 .

[0059] In this embodiment, the second bracket 41 in a second limiting mechanism 4 can be combined with the second bracket 41 of an adjacent second limiting mechanism 4, that is, the adjacent sliding rods 44 of the two second limiting mechanisms 4 are connected to the same second bracket 41, thereby reducing the number of second brackets 41 and improving the integrity of the structure; furthermore, a roller 411 is provided on the second bracket 41, and when the material is transported to the destination, the material can be fitted with the roller 411, and the rotation of the roller 411 assists in material unloading, which can save manpower.

[0060] As a preferred embodiment, a cylinder is provided on the base 1, and a transmission rod is connected to the output end of the cylinder, and the transmission rod is also connected to the placement plate 2. Under the drive of the cylinder and the transmission rod, the placement plate 2 is lifted or lowered.

[0061] In this embodiment, by controlling the telescopic movement of the output end of the cylinder, the transmission rod is moved upward or downward, thereby realizing the height adjustment of the placement plate 2. When loading or unloading materials, the placement plate 2 can be lowered to make it more convenient for the materials to be loaded and unloaded. During transportation, the placement plate 2 can be raised to facilitate applying force to the handling device to make it move.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
