Description

Technical Field

[0001] This utility model relates to the field of mechanical automation equipment technology, specifically to a side-push type support bar feeding device, used to realize the automated and continuous feeding and discharging of support bar materials. Background Technology

[0002] In the transformer oil curtain manufacturing industry, support bars are a common component, and their efficient and accurate feeding and conveying are crucial aspects of automated production. Currently, the common method for feeding support bars is to use a single hopper in conjunction with a pushing mechanism.

[0003] However, existing technical solutions mainly have the following problems and drawbacks: 1. Poor flexibility and difficulty in adapting to multi-specification production: Existing silos are mostly fixed structures, and their size and number cannot be adjusted. When different lengths, quantities, or specifications of support bars need to be processed during production, the machine must be stopped and the entire silo or equipment must be replaced, which seriously affects the flexibility and efficiency of the production line and cannot meet the production needs of small-batch, diversified products.

[0004] 2. Low level of automation and insufficient production continuity: Most equipment adopts a single-bin design. When the support bars in a bin are exhausted, the current operation must be interrupted and replenished manually. It is impossible to achieve automatic switching and continuous feeding between different bins. This intermittent operation mode leads to low production efficiency and increases labor costs and labor intensity.

[0005] 3. The stability and reliability of the feeding mechanism need to be improved: Some existing feeding mechanisms use simple cylinders to directly drive the push rod. During reciprocating motion, they lack effective guidance and anti-sway structures, which can easily lead to problems such as push bar jamming, accelerated wear, or uneven ejection force. This not only affects the accuracy of material feeding but may also cause damage to the support bar surface or equipment malfunction and downtime, resulting in high maintenance costs. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to provide a support bar unloading device that can flexibly adjust the bin capacity, realize automatic continuous feeding and stable and reliable feeding. This utility model provides a side-push support bar unloading device, which realizes flexible adjustment of bin capacity and automatic switching of feeding through the coordinated cooperation of modular bins and moving components; and realizes efficient, stable and continuous ejection of support bars through a stable pushing mechanism.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a side-push type support bar unloading device, including a frame, a hopper, a pushing component, and a moving component; the hopper is set on the moving component, and the pushing component is arranged on one side of the frame; the hopper includes a bottom plate, a side plate, and multiple partitions, the partitions dividing the interior of the hopper into multiple independent compartments, each compartment having a through groove at its bottom; the pushing component includes a drive mechanism and a push bar, the drive mechanism driving the push bar to reciprocate horizontally, the front end of the push bar extending into the through groove to push out the support bar; the moving component includes a drive motor and a transmission mechanism, the drive motor driving the hopper to move along the length of the frame through the transmission mechanism to achieve alignment between different compartments and the push bar.

[0008] In the aforementioned side-push support bar unloading device, the driving mechanism of the pushing component is a cylinder.

[0009] In the aforementioned side-push type support bar unloading device, the cylinder is a magnetically coupled rodless cylinder.

[0010] The aforementioned side-push support bar feeding device further includes a first slide rail and a first slider, wherein the first slider is connected to the push bar and slides along the first slide rail.

[0011] The aforementioned side-push support bar unloading device includes a transmission mechanism for the moving component comprising a belt, pulleys, and clamping blocks. The belt is connected to the base of the hopper via the clamping blocks.

[0012] In the aforementioned side-push support bar unloading device, the drive motor of the moving component is a servo motor.

[0013] The aforementioned side-push support bar unloading device further includes a second slide rail and a second slider in the moving component. The second slider is disposed at the lower part of the base and slides in cooperation with the second slide rail.

[0014] The aforementioned side-push type support bar material feeding device includes a hopper that further comprises multiple hopper bars arranged along the length of the bottom plate, with adjacent hopper bars connected by partitions to form a hopper body.

[0016] The aforementioned side-push support bar unloading device also includes a control unit, which is used to control the coordinated action of the pushing component and the moving component.

[0017] The beneficial effects of this utility model are: 1. The capacity of the hopper is flexibly adjustable, and users can easily increase or decrease the number of hoppers according to production needs, effectively adapting to the unloading tasks of different specifications of support bars, and improving the versatility and production efficiency of the equipment.

[0018] 2. It realizes automatic cyclic switching and continuous operation of multiple compartments. After the material in one compartment is used up, it can automatically move the next full compartment to the working position, avoiding production interruption and frequent manual replenishment, and has a high degree of automation.

[0019] 3. Significantly improves the stability and reliability of the feeding process.

Detailed Implementation

[0027] This embodiment provides a side-push type support bar unloading device. Its core function is to achieve efficient and continuous unloading of support bars through modular bin switching and top-out pusher operation. Figure 1-5As shown, the device consists of four parts: frame 1, hopper 2, pusher assembly 3, and moving assembly 4. Frame 1 serves as the basic support frame, with a pre-reserved mounting surface on top for fixing the base 45 and second slide rail 47 of moving assembly 4. The hopper 2 is composed of a bottom plate 21, side plates 22, hopper bars 23, and partitions 24, which are fixed to the base 45 of moving assembly 4 by bolts. The interior of hopper 2 is divided into multiple independent hoppers by multiple sets of partitions 24. Each hopper has a through groove 26 at the bottom, the height of which is slightly greater than the thickness of the support bar, to ensure that the pusher bar 34 can smoothly push out the support bar. Pusher assembly 3 is vertically arranged on one side of frame 1 and drives pusher bar 34 to reciprocate horizontally through cylinder 32 to push out the support bar and drop the material. Moving assembly 4 is driven by servo motor 41 and belt 43 to drive hopper 2 to move linearly along the length of frame 1, realizing the switching of hoppers.

[0028] The pushing assembly 3 includes a base 31, a cylinder 32, a plate base 33, a pusher 34, a first slider 35, and a first slide rail 36. The cylinder 32 is an Airtac RMS series magnetic coupling rodless cylinder 32. The piston rod is fixed to the upper part of the base 31 at both ends by a bracket, and an air inlet and an air outlet are respectively provided at both ends. The moving slider is sleeved on the surface of the piston rod. The magnetic coupling technology realizes contactless driving and reduces wear. The upper part of the moving slider is connected to the plate base 33 by bolts. The pusher 34 is fixed to one side of the plate base 33 by bolts. The front end of the pusher 34 has a flat structure, and its width matches the width of the through groove 26 of the bin body to ensure that the support bar is evenly stressed when ejecting. The first slide rail 36 is arranged side by side on one side of the cylinder 32. The first slide rail 36 is fixed to the base 31 by bolts. The first slider 35 is bolted to the pusher 34 and slides linearly along the first slide rail 36, which effectively suppresses the swaying of the pusher 34 during reciprocating motion and improves stability.

[0029] Operation process: Cylinder 32 takes in air, the piston rod drives the moving slider to move the push bar 34 forward, the front end of the push bar 34 extends into the through groove 26 of the bin body, pushes out the support bar to drop the material. After the push is completed, cylinder 32 exhausts air, and the push bar 34 returns to the initial position under the action of the return spring (or reverse air intake). The first slider 35 slides synchronously along the first slide rail 36 to ensure that the movement trajectory of the push bar 34 is straight.

[0030] The moving component 4 includes a motor 41, pulleys 42, belt 43, clamping block 44, base 45, second slider 46, and second slide rail 47. The base 45 is horizontally arranged on the top of the frame 1 and serves as the mounting carrier for the hopper 2. The second slider 46 is symmetrically arranged at the bottom of the base 45 and slides in cooperation with the second slide rail 47 on the frame 1 to achieve low-friction linear movement. The pulleys 42 are mounted at both ends of the frame 1 through bearing seats. One of the pulleys 42 is keyed to the output shaft of the servo motor 41. The belt 43 is sleeved between the two pulleys 42. The lower part of the base 45 is fastened to the belt 43 through the clamping block 44. The motor 41 adopts a timing control method and sets the running interval and number of revolutions through the PLC. For example, when a hopper support bar is pushed to its limit, the motor 41 starts and drives the belt 43 to move the base 45 by one hopper spacing so that the next hopper is aligned with the push bar 34.

[0031] Bin switching logic: In the initial state, one of the bins of bin 2 is located in front of push bar 34. Pushing component 3 starts to push out. Sensors (such as photoelectric switches) detect whether the support bars in the bin are completely discharged, or the timer estimates the pushing time. After receiving the signal, PLC controls servo motor 41 to run a preset number of revolutions, drives base 45 to move to the next bin position, and repeats the above process to realize continuous feeding of multiple bins.

[0032] The hopper 2 consists of a bottom plate 21, side plates 22, hopper bars 23, and partitions 24. The hopper bars 23 are arranged side by side along the length of the bottom plate 21 and are fixed at both ends by the side plates 22. The hopper bars 23 have pre-set screw holes 25, and the number of hopper bars 23 can be increased or decreased by passing through the screws. Adjacent hopper bars 23 are connected by bolts to the partitions 24 to form independent hopper bodies. For example, adding a set of hopper bars 23 and partitions 24 can add a new hopper body. Users can flexibly adjust the number of hopper bodies according to the specifications of the support bars (such as length and quantity) to meet diverse production needs.

[0033] Taking three bins as an example, the complete operation process of the device is explained as follows: In the initial state, bin A is located in front of push bar 34. Cylinder 32 drives push bar 34 to push out the support bar inside bin A. After the sensor detects that there is no support bar, PLC controls servo motor 41 to run, driving bin 2 to move so that bin B is aligned with push bar 34. Push bar 34 continues to push out the support bar of bin B. At the same time, bin C is in standby state. After bin B is emptied, step 2 is repeated to switch to bin C until all bins are emptied.
