Description

Technical Field

[0001] The invention relates to the field of conveying equipment, in particular to an automatic stacking conveying device. Background Art

[0002] In the field of sheet metal production and manufacturing, conveying devices generally transport products to different workstations for processing. Some workstations perform material loading and processing intermittently, while the upstream process of the conveying device can only output products continuously. Sometimes, when the upstream workstation has a short downtime, this will cause product accumulation and material shortage in the downstream workstation. For example, in the rotary kiln firing process in the glass industry, empty molds enter the rotary kiln (that is, only the molds enter the rotary kiln for firing), which means material shortage. This has a certain impact on product quality and molds. Dry firing of molds can easily damage them, affecting subsequent use and reducing product quality. Summary of the invention

[0003] The object of the present invention is to provide an automatic stacking and conveying device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The present invention provides an automatic stacking conveying device, which comprises: a conveying mechanism and a stacking lifting mechanism, wherein the conveying mechanism is provided with a conveying platform structure whose conveying direction is in the left and right direction; the stacking lifting mechanism comprises a material storage component and a lifting drive component, wherein the material storage component comprises two vertically arranged material storage plates, the two material storage plates are relatively parallelly arranged on the front and rear sides of the conveying platform structure, the sides of the two material storage plates facing each other are inner plate surfaces, and the sides of the two material storage plates facing away from each other are outer plate surfaces, a plurality of material storage troughs extending left and right are arranged on the two inner plate surfaces, and the plurality of material storage troughs on each of the material storage plates are arranged in an upper and lower interval arrangement, and the lifting drive component is provided with a lifting drive end which is transmission-connected to the two material storage plates and enables the two material storage plates to move up and down relative to the conveying platform structure.

[0006] The beneficial effect of the present invention is that when in use, the glass plate is conveyed along the conveying platform structure. When there are products waiting to be grabbed at the discharge direction station on the conveying platform structure, and the glass at the feed direction station has also reached the designated position, the designated position is the position between the two storage plates. At this time, the two side edges of the glass plate extend into the corresponding two storage slots, and the lifting drive component drives the two storage plates to rise one grid relative to the conveying platform structure, and the glass plate is lifted from the conveying platform structure, which is equivalent to storing a piece of glass plate. The pair of storage slots below also rise to a position level with the conveying platform structure, which can be used for the passage or support of the rear glass. When there are no products at the discharge direction station on the conveying platform structure, and there is no glass plate incoming at the feed direction station, the lifting drive component drives the two storage plates to fall one grid relative to the conveying platform structure to deliver a glass plate, and the cycle is repeated. In this way, the output of products can be ensured without material shortage. Secondly, the needs of intermittent discharge and continuous feeding can be met to avoid product accumulation.

[0007] As a further improvement of the above technical solution, the distance between the two material storage plates in the front-to-back direction is adjustable. In this way, the distance between the two material storage plates can be adjusted according to glass plates of different widths, so that the material storage trough can support both sides of the glass plate to meet the production of multiple products.

[0008] As a further improvement of the above technical solution, the stacking and lifting mechanism also includes two lifting plate seats, and two material storage plates are respectively arranged on the lifting plate seats. The material storage plates are adjusted forward and backward and installed on the lifting plate seats. The material storage plates are transmission connected to the lifting drive assembly through the lifting plate seats.

[0009] Each material storage plate in this solution can be adjusted forward and backward on the lifting plate seat, which can improve the flexibility of adjustment and changeover, and the lifting drive component only drives the lifting plate seat to move up and down to drive the material storage plate to move up and down, which is simpler in transmission structure.

[0010] As a further improvement of the above technical solution, the automatic stacking and conveying device also includes a frame, the lifting plate seat is connected to the frame in a sliding manner up and down, the outer plate surface is slidably connected to a plurality of guide holes opened on the lifting plate seat through a plurality of guide shafts, the guide shaft is extended forward and backward, a locking flange is provided on the lifting plate seat, the guide shaft is slidably sleeved on the locking flange, and a locking screw for locking and fixing the guide shaft is provided on the locking flange.

[0011] The sliding cooperation between the guide shaft and the guide hole can improve the stability of the storage plate adjustment. In this solution, an oil-free copper sleeve can be set on the guide hole to improve the smoothness of sliding. After adjusting the front and rear positions of the storage plate, tighten the locking screws on the locking flange to lock the guide shaft.

[0012] As a further improvement of the above technical solution, the lifting drive assembly includes two lifting pulley structures and a rotation drive unit. The two lifting pulley structures are respectively arranged on the front and rear sides of the conveying platform structure. The lifting pulley structure includes two lifting transmission wheels arranged on the frame with an upper and lower interval, and a lifting transmission belt connected between the two lifting transmission wheels. The two lifting transmission belts are respectively connected to the two lifting plate seats through belt clamps, and the rotation drive unit is connected to the two lifting transmission wheels opposite to each other through a lifting transmission shaft.

[0013] The rotary drive unit in this solution synchronously drives the two lifting plate seats to lift and lower through two lifting pulley structures. The lifting pulley structure is a pulley drive of a lifting transmission wheel and a lifting transmission belt, which is simpler in structure and has low manufacturing cost.

[0014] As a further improvement of the above technical solution, the conveying platform structure includes two conveying sections connected left and right, the two conveying sections are divided into a feeding conveying section and a discharging conveying section, the feeding conveying section and the discharging conveying section are independently driven, and the stacking lifting mechanism is arranged in the feeding conveying section.

[0015] The conveying platform structure in this scheme is divided into a feeding conveying section and a discharging conveying section which are independently driven. The stacking and lifting mechanism stacks and stores the glass plates on the feeding conveying section, while the discharging conveying section is responsible for discharging. This is equivalent to the conveying platform structure in this scheme having unsynchronized feeding and discharging, thereby meeting intermittent feeding and discharging needs.

[0016] As a further improvement of the above technical solution, the automatic stacking conveying device further comprises a frame, the conveying section comprises a plurality of conveying rollers extending forward and backward and a conveying drive assembly, the plurality of conveying rollers are arranged on the frame at intervals left and right, and the conveying drive assembly drives the plurality of conveying rollers to rotate synchronously. In this solution, the glass sheet is supported and conveyed by the plurality of conveying rollers.

[0017] As a further improvement of the above technical solution, the conveying roller body includes a conveying driven shaft rotatably mounted on a frame, a plurality of contact wheels fixedly mounted on the conveying driven shaft, and a driven magnetic wheel fixedly mounted on the driven shaft. The conveying drive assembly includes a driving shaft, a conveying drive unit for driving the driving shaft to rotate, and a plurality of driving magnetic wheels fixedly mounted on the driving shaft. The driving magnetic wheel and the driven magnetic wheel are magnetically coupled and transmitted one by one.

[0018] This solution realizes contactless transmission through magnetic coupling transmission between the driving magnetic wheel and the driven magnetic wheel. The conveying drive unit drives multiple driving magnetic wheels to rotate through the driving shaft. Under the action of magnetic force, each driving magnetic wheel drives the corresponding driven magnetic wheel to rotate, thereby driving multiple conveying driven shafts to rotate synchronously. It has high power transmission capacity, is noiseless, and does not require frequent replacement of parts.

[0019] As a further improvement of the above technical solution, the automatic stacking conveying device also includes a feed conveyor line, the end of the feed conveyor line is connected to the conveying feed end of the conveying platform structure, the feed conveyor line is provided with an alignment module, the alignment module includes two alignment components arranged on the front and rear sides of the feed conveyor line in a front-to-back relationship, and an alignment drive component for driving the two alignment components to move closer to or away from each other.

[0020] This solution takes into account that it is difficult for glass plates to maintain a set posture position on the feed conveyor line, and thus provides an alignment module to align the glass plates and adjust them to a conveying posture that matches the two storage plates. Specifically: when the glass plates are conveyed between the two alignment components, the alignment drive component drives the two alignment components to approach each other, thereby clamping the glass plates in place.

[0021] As a further improvement of the above technical solution, the aligning component is provided with a plurality of rollers, and the plurality of rollers are arranged in a left-right interval.

[0022] The aligning assembly in this solution contacts the side of the glass plate through a plurality of rollers, which does not affect the movement and transportation of the glass plate and maintains continuous feeding of the glass plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The automatic stacking and conveying device of this embodiment includes a frame 400, a conveying mechanism and a stacking and lifting mechanism, wherein the conveying mechanism is provided with a conveying platform structure 100 with a conveying direction in a left-right direction.

[0033] The stacking and lifting mechanism includes a material storage component, a lifting drive component, and two lifting plate seats 300. The material storage component includes two vertically arranged material storage plates 200, and the two material storage plates 200 are arranged in parallel on the front and rear sides of the conveying platform structure 100 in a front-to-back manner.

The rotation drive unit includes a servo motor, and the servo motor is connected to the lifting transmission shaft through a synchronous pulley structure.

[0036] When in use, the glass sheet is transported along the conveying platform structure 100. When there are products waiting to be grabbed at the discharge direction station on the conveying platform structure 100, and the glass at the feed direction station has also reached the designated position, which is the position between the two storage plates 200, the two sides of the glass sheet extend into the corresponding two storage slots 210, and the lifting drive assembly drives the two storage plates 200 to rise one grid relative to the conveying platform structure 100, and the glass sheet is lifted from the conveying platform structure 100, which is equivalent to storing a piece of glass sheet, and the pair of storage slots below The material trough 210 also rises to a position level with the conveying platform structure 100, so that the glass behind can pass through or be supported for lifting; when there is no product at the discharge direction station on the conveying platform structure 100, and there is no glass plate incoming at the feed direction station, the lifting drive assembly drives the two storage plates 200 to drop one grid relative to the conveying platform structure 100, and delivers a glass plate, and the cycle is repeated. This ensures that there is product output and there will be no shortage of materials. It can also meet the needs of intermittent discharge and continuous feeding to avoid product accumulation.

The conveying drive unit also includes a servo motor, which is connected to the driving shaft 440 through a synchronous pulley structure, and realizes contactless transmission through magnetic coupling transmission between the driving magnetic wheel 441 and the driven magnetic wheel 432. The conveying drive unit drives multiple driving magnetic wheels 441 to rotate through the driving shaft 440. Under the action of magnetic force, each driving magnetic wheel 441 drives the corresponding driven magnetic wheel 432 to rotate, thereby driving multiple conveying driven shafts 430 to rotate synchronously, with high power transmission capacity, no noise, and no need for frequent replacement of parts.
