Description

Technical Field

[0001] The utility model belongs to the technical field of automated tooling, and in particular relates to a double-row automatic feeding and discharging vehicle. Background Art

[0002] At present, the automation level of various production lines is getting higher and higher, and the requirements for lean production are also constantly increasing. On many semi-automatic production lines, most operations have been completed by automated equipment such as robots. However, some production links still need to be completed manually. For example, some parts assembly links are still completed manually by workers. In this work scenario, material racks are usually placed next to the automatic production line, and material boxes containing parts are placed on the material racks. Workers need to take out the parts to be assembled from the material boxes, and then manually place the empty material boxes to other locations after completing assembly and other operations.

[0003] In the semi-automatic production line, such workers frequently manually invert the empty material boxes. In order to save the workers' time in manually inverting the empty material boxes, it is necessary to design a simple universal tooling that can automatically deliver the material boxes to the workers' operating positions (i.e., automatic feeding) and automatically transport the empty material boxes (i.e., automatic discharge) after the workers complete the assembly. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a double-row automatic feeding and discharging material trolley.

[0005] The utility model solves the technical problem through the following technical solutions:

[0006] A double-row automatic feeding and discharging material trolley comprises a main frame, and the four corners of the main frame are provided with anchor pulleys, characterized in that: the front end of the main frame is provided with a material box turning mechanism, a material box lifting mechanism and a cylinder in sequence from top to bottom, and the rear end of the main frame is provided with a double-row upper fixed slideway and a lower fixed slideway, the upper fixed slideway is inclined from back to front, and the lower fixed slideway is inclined from front to back, a material blocking rod is slidably provided at the top end of the main frame, and the cylinder drives the material box lifting mechanism to drive the material box turning mechanism to move upward until the material box turning mechanism is The inclination angle of the mechanism is the same as that of the upper fixed slide. The material box filled with materials placed on the upper fixed slide moves forward under the action of gravity. The materials are taken away manually and the material blocking rod descends at the same time to prevent the subsequent material boxes filled with materials from moving forward. The empty material box follows the material box lifting mechanism to descend on the material box turning mechanism. When it reaches the vicinity of the lower fixed slide, the turning inclination angle of the material box turning mechanism is adjusted to be the same as the inclination angle of the lower fixed slide and docked. The empty material box automatically slides out along the lower fixed slide under the action of gravity, completing a feeding and discharging operation.

[0007] Moreover, the material box flipping mechanism includes a baffle, a rotating pallet, a flipping slide, a rotating shaft and a limiting column. The baffle is arranged on the side of the rotating pallet, the flipping slide is arranged on the rotating pallet, the rotating pallet rotates along the rotating shaft, and the limiting column is arranged at the bottom end of the main frame.

[0008] Moreover, the material box lifting mechanism includes a lifting guide column, a lifting pallet, a fixed pulley, a rope, a movable pulley and a lifting pulley. The lifting pulley is connected to the lifting pallet. The cylinder drives the pulley group composed of the fixed pulley, the rope, the movable pulley and the lifting pulley to lift and lower and drives the lifting pallet to lift and lower. The lifting pallet moves up and down along the lifting guide column.

[0009] Moreover, an upper guide plate and a lower guide plate are respectively arranged in the middle of the upper fixed slideway and the lower fixed slideway.

[0010] Moreover, the inclination angles of the upper fixed slideway and the lower fixed slideway are 5 to 10 degrees.

[0011] Moreover, the upper fixed slideway, the lower fixed slideway and the flip slideway are all made of smooth strips.

[0012] The advantages and beneficial effects of the utility model are:

[0013] 1. The double-row automatic feeding and discharging material cart of the utility model adopts the lifting of the material blocking rod of the mechanical structure to achieve the purpose of preventing or releasing the unused material box on the upper layer from sliding down, and the mechanical structure is simple to operate and has good reliability, avoiding the design of commonly used electrical blocking, simplifying the electrical control system, and having low cost.

[0014] 2. The double-row automatic feeding and discharging material trolley of the utility model is provided with an upper guide plate and a lower guide plate in the middle of the upper fixed slide and the lower fixed slide respectively, which can avoid the possibility of box jamming due to unstable movement during the upper and lower layer transportation of the material trolley, and avoid the occurrence of box jamming.

[0015] 3. The double-row automatic feeding and discharging material cart of the utility model has an upper fixed slideway tilted from back to front, and a lower fixed slideway tilted from front to back. The upper fixed slideway and the lower fixed slideway have opposite inclination angles. The empty material box also needs to adjust its inclination angle during the process of descending with the material cart lifting mechanism to ensure that the empty box can dock with the lower slideway after falling to the lower layer of the material cart. Based on the above requirements, a material box flipping mechanism is designed on the material cart lifting mechanism. By controlling the rotation angle of the rotating support plate in the flipping mechanism, the rotation angle of the rotating mechanism slideway after descending or ascending is adjusted. The tilt angle is that when the empty material box descends to the lower layer, the flipping mechanism can dock the slide of the flipping mechanism with the slide of the lower layer to complete the empty material box discharge action; when the lifting mechanism rises to the upper layer, the flipping mechanism can dock the slide of the flipping mechanism with the slide of the upper layer, so that the material box loaded with parts on the upper layer of the material cart slides down to the material box lifting mechanism under the action of gravity. The structural design of the "lifting mechanism and material box flipping mechanism" of the material cart is compact, which can realize the lifting and sliding connection of the material box in a limited space, and is especially suitable for working occasions where large-volume material boxes are automatically fed and discharged.

[0016] 4. The double-row automatic feeding and discharging material cart of the utility model adopts a lifting mechanism in which a cylinder drives a movable pulley block, which can greatly shorten the cylinder stroke and reduce costs.

[0017] 5. The double-row automatic feeding and discharging material cart of the utility model improves the automation level of the production line, saves working hours, and eliminates the step of workers manually pouring the empty boxes to other locations after using up the materials on the material rack.

[0028] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0029] like Figure 1 As shown, a double-row automatic feeding and discharging material cart is innovative in that it includes a main frame 1, the four corners of the main frame 1 are provided with anchor pulleys 10, the front end of the main frame 1 is provided with a material box flipping mechanism 2, a material box lifting mechanism 3 and a cylinder 4 in sequence from top to bottom, the rear end of the main frame 1 is provided with a double-row upper fixed slide 6 and a lower fixed slide 9, the upper fixed slide 6 is inclined from back to front, the lower fixed slide 9 is inclined from front to back, a material blocking rod 5 is slidably provided at the top of the main frame 1, and the cylinder 4 drives the material box lifting mechanism to drive the material box flipping mechanism to The material box moves upward until the inclination angle of the material box turning mechanism is the same as that of the upper fixed slide. The material box filled with materials placed on the upper fixed slide moves forward under the action of gravity. The materials are taken away manually and the material blocking rod descends at the same time to prevent the subsequent material boxes filled with materials from moving forward. The empty material box follows the material box lifting mechanism to descend on the material box turning mechanism. When it reaches the vicinity of the lower fixed slide, the turning inclination angle of the material box turning mechanism is adjusted to be the same as the inclination angle of the lower fixed slide and docked. The empty material box automatically slides out along the lower fixed slide under the action of gravity, completing a feeding and discharging operation.

[0030] The material box turning mechanism 2 includes: a baffle 21, a rotating support plate 22, a turning slide 23, a rotating shaft 24 and a limiting column 25;

[0031] The material box lifting mechanism 3 includes a lifting mechanism guide column 31 , a lifting support plate 32 , a fixed pulley 33 , a rope 34 , a movable pulley 35 and a lifting pulley 36 .

[0032] The upper fixed slide 6, the lower fixed slide 9 and the flip slide 23 all adopt a smooth strip structure. In order to ensure that the material box slides smoothly on the slide, the inclination angle of the smooth strip slide can be arranged in the range of 5 to 10° according to the material, size and weight specifications of the material box. If the material is heavy, other material conveying forms such as rollers can also be used. The bottom of the material cart is equipped with a ground roller 10 with a brake function, which can facilitate the movement and fixation of the material cart. There is a possibility that the double-row material box will be stuck due to unstable movement during the transportation process. In order to avoid the occurrence of the box jam phenomenon, an upper guide plate 7 and a lower guide plate 8 are set in the middle of the upper and lower slides of the material cart.

[0033] The feeding and discharging working process of the utility model is:

[0034] 1. Workers place the material boxes 11 containing materials in the form of 2×3 on the upper layer of the material car. Figure 2 As shown, the material box lifting mechanism 3 drives the material box turning mechanism 2 to move to the upper layer of the material car, and the upper fixed slideway 6 and the turning slideway 23 have the same inclination angle and are connected, as shown in FIG. Figure 3 shown.

[0035] 2. The worker's operating station is next to the material box lifting mechanism 3. The worker takes out the parts in the two material boxes on the lifting mechanism 3 and completes the required operations. When the two material boxes are empty, Figure 4 As shown, the lifting mechanism 3 is started, and the two empty material boxes 12 on the material box turning mechanism 2 are driven to descend;

[0036] 3. At this time, the material blocking rod 5 also descends to prevent the other four material boxes containing parts from sliding down. Figure 4 shown. Figure 5 When the rotating pallet 22 contacts the limiting column 25, the rotating pallet 22 starts to rotate around the rotating axis 24, causing the inclination angle of the slide 23 of the flipping mechanism to flip until it has the same inclination angle as the lower fixed slide 9 and docks with it, and then the two empty boxes automatically slide out along the slide 9 under the action of gravity.

[0037] 4. The lifting mechanism 3 rises to the upper layer of the material cart again. During the rising process, when the rotating support plate 22 separates from the limiting column 25, the flip slide 23 is adjusted to the same inclination angle as the upper slide 6. At the same time, the material box blocking rod 5 rises to release the other four material boxes containing parts on the upper layer. Under the action of gravity, the material boxes slide down along the slide to the top of the material box flip mechanism 2, and the workers start a new round of operations to take materials from the material boxes.

[0038] This material cart uses a cylinder to drive a pulley block to achieve the lifting of the two layers of materials on the material cart. Figure 6As shown. The lifting pulley 36 is connected to the lifting mechanism support plate 32, and the cylinder 4 drives the movable pulley group 35 to rise (or fall), causing the lifting pulley 36 to fall (or rise), thereby driving the lifting mechanism support plate 32 to fall (or rise). The number of movable pulleys in the lifting mechanism can be selected according to the cylinder stroke and the material lifting height requirements. Generally, the larger the cylinder stroke, the more expensive it is. This material car adopts a lifting system with a movable pulley group, which can greatly shorten the cylinder stroke. For example, if the height to be lifted for an empty material box is 500mm, use Figure 6 In the movable pulley block structure shown, the stroke ratio of the cylinder 4 and the lifting pulley 36 is 1:4. That is, when the stroke of the cylinder is 500 / 4=125mm, the requirement of the 500mm stroke of the material car lifting mechanism can be met.
