Abstract
Description
Technical Field

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0030] First, combine Figures 1-4 The lifting and weighing fixture according to an embodiment of the present invention is used to lift and weigh pallets and products loaded on pallets, and its application scenarios are very wide.
[0031] like Figures 1-4 As shown, the lifting and weighing fixture of this utility model embodiment includes: a support frame 1, a lifting frame 2, a guide mechanism 3, a lifting mechanism 4, and a weighing component 5.
[0032] Specifically, such as Figures 1-4 As shown, in this embodiment, the lifting frame 2 is placed on the support frame 1. The lifting frame 2 positions and supports the external pallet, which carries the products and flows to the lifting frame 2 via an external conveyor line. The lifting frame 2 positions and lifts the pallet. The guide mechanism 3 is connected to the lifting frame 2 and slidably connected to the support frame 1. The guide mechanism 3 limits the vertical movement of the lifting frame 2, both guiding its movement and restricting it to vertical motion only. The weighing element 5 is installed on the lifting frame 2 and weighs the pallet. The lifting mechanism 4 is installed on the support frame 1 and connected to the lifting frame 2. The lifting mechanism 4 drives the lifting frame 2 to rise and fall. As the lifting frame 2 rises, it causes the pallet to detach from the current conveyor line for weighing. In this embodiment, the weighing element 5 is a load cell that weighs the pallet and the products on it.
[0033] Furthermore, such as Figures 1-4 As shown, in this embodiment, the guiding mechanism 3 includes: a plurality of guide posts 31 and a plurality of sliding bearings 32; the plurality of sliding bearings 32 are fixed on the support frame 1; the top ends of the plurality of guide posts 31 are fixed on the lifting frame 2, and the bottom ends of the plurality of guide posts 31 are respectively inserted into the plurality of sliding bearings 32; the guide posts 31 are slidably connected to the support frame 1 through the sliding bearings 32, and the guide posts 31 limit the vertical movement of the lifting frame 2. In this embodiment, the number of guide posts 31 can be set to three, four, five, etc., as needed. If there are four, the four guide posts 31 are respectively set at the four corners of the lifting frame 2. In this embodiment, the guiding mechanism 3 can also be a slide rail slider guiding mechanism 3.
[0034] Furthermore, such as Figures 1-4 As shown, in this embodiment, the top surface of the lifting frame 2 is provided with a plurality of positioning blocks 21, and the plurality of positioning blocks 21 correspond one-to-one with a plurality of positioning holes on the tray. The positioning blocks 21 position the tray, and the tray has bushing holes. The positioning blocks 21 can be inserted into the bushing holes on the tray to achieve precise positioning after lifting.
[0035] Furthermore, such as Figures 1-4 As shown, in this embodiment, the lifting mechanism 4 includes: a pair of guide rails 41, four inclined guide blocks 42, four guide wheels 43, a connecting frame 44, and a driving component 45; the pair of guide rails 41 are fixed parallel to each other on the support frame 1; the connecting frame 44 is H-shaped, with the H-shaped frame symmetrically distributed to evenly bear the lifting load, and the two sides of the connecting frame 44 are slidably mounted on the pair of guide rails 41, with the guide rails 41 constraining the connecting frame 44 to slide only in the horizontal direction; the four inclined guide blocks 42 are respectively located at the four corners of the connecting frame 44, and the four inclined guide blocks 42 have the same inclination direction; the four guide wheels 43 are respectively fixed to the bottom surface of the lifting frame 2. At each of the four corners, there is a corresponding inclined guide block 42. The guide wheel 43 is in contact with the inclined surface of the inclined guide block 42. The driving component 45 is fixed on the support frame 1. The output end of the driving component 45 is connected to the connecting frame 44. The driving component 45 drives the connecting frame 44 to move along the guide rail 41, drives the four inclined guide blocks 42 to slide horizontally, and drives the lifting frame 2 to lift. When the connecting frame 44 moves horizontally, the inclined guide blocks 42 push the guide wheel 43 to slide along the inclined surface, converting the horizontal movement into the vertical lifting of the lifting frame 2. By changing the tilt angle of the inclined guide blocks 42, the lifting height can be flexibly controlled to adapt to different pallet and conveyor line spacings. In this embodiment, the driving component 45 is a cylinder, which has a fast response, simple control, and convenient maintenance.
[0036] Furthermore, such as Figures 1-4 As shown, in this embodiment, the inclined guide block 42 is provided with limit blocks 46 at both ends. The limit blocks 46 limit the movement range of the guide wheel 43. By physically limiting the sliding range of the guide wheel 43 on the inclined guide block 42, it is ensured that the lifting stroke of the lifting frame 2 is always within the preset range.
[0037] Working principle: When a pallet on the conveyor line moves to above the lifting area, and the proximity sensor on the conveyor line detects the pallet, the stop cylinder on the line opens, stopping the pallet's movement. A cylinder extends, driving the inclined guide block 42 to move to its highest point, lifting the pallet and detaching it from the conveyor line. The pallet and products above the lifting mechanism 4 are then weighed. After completion, the cylinder retracts, driving the inclined guide block to its lowest point, and the pallet falls back onto the conveyor line. The stop cylinder retracts, releasing the pallet, which then moves to the next station, and the cycle repeats.
[0038] Above, refer to Figures 1-4 The present invention describes a lifting and weighing fixture according to an embodiment of the present invention, which is highly integrated with the conveyor line, enabling real-time weighing of products during product conveying, resulting in fast production cycle and high efficiency; the overall structure is simple, the cost is low, the operating cost is low, and the automated operation is achieved, greatly improving the efficiency of lifting work.
