Description

Technical Field

[0001] The invention relates to the technical field of wood processing, in particular to a device and a conveying process for destacking and conveying multi-layer wood strips. Background Art

[0002] Strip wood has been widely used due to its hardness, wear resistance, corrosion resistance, good adhesion, good processing properties, strong nailing strength, etc. Most of the strip wood currently used in the market is produced uniformly from strip wood processing factories;

[0003] In order to facilitate the transportation of wood strips, wood strip processing plants will stack the produced wood strips into wood strip piles for unified transportation. Therefore, when faced with piles of wood strips, most of the existing technologies use loading devices to grab the wood strips of each layer and transport them to the wood strip processing equipment for processing. However, since the overall size of the transported wood strip piles is large, on the one hand, the loading device can adapt to the limited size of wood strips to be grabbed, and on the other hand, the number of wood strips used by the wood strip processing equipment also varies. Therefore, before the wood strips are loaded, the wood strip piles need to be manually decomposed into small wood strip piles that meet the loading conditions of the wood strip processing equipment for loading, which increases the labor cost of destacking. At the same time, when grabbing the wood strips, relying on the clamping force to clamp the workpiece can easily cause the wood strips to roll and fall off, and the loading device grabs the upper wood strips and pulls up the lower wood strips, causing equipment failure. Summary of the invention

[0004] The present invention solves the problem in the prior art that before loading the strips, the strips need to be manually destackered into small strips that meet the loading conditions of the strip processing equipment, which increases the labor cost of destacking; and eliminates the problem that when the loading device grabs multiple strips, the strips on the same layer roll over and the strips on the lower layer are lifted when grabbing the upper strips. The present invention provides a multi-layer strip destacking conveying device and conveying process, which automatically conveys a set number of strips to the processing equipment according to the use requirements, avoids heavy destacking labor, ensures the reliability of strip loading, reduces production costs, and improves processing efficiency.

[0009] Furthermore, the material receiving platform is provided with an end baffle plate at the end of one side of the feed scraper. When the horizontal drag plate moves the wood strips to the material receiving platform, the end baffle plate can block the adjacent lower layer wood strips to avoid the lower layer wood strips being brought out together.

[0010] Furthermore, the feeding mechanism is provided with a lifting detection switch, which may adopt a sensor.

Therefore, they cannot be understood as limitations on the present invention.

[0028] Example 1

[0029] Figure 1 and Figure 2 The schematic diagram of the cooperation between the multi-layer wood strip layered destacking and conveying device and the material stack 14 provided in this embodiment includes: a frame 1, which is arranged next to the material stack 14; a material receiving platform 2 is arranged on the frame 1, and the material receiving platform 2 is connected to the lifting mechanism; a feeding mechanism and a discharging mechanism are also arranged on the frame 1; the lifting mechanism moves the material receiving platform 2 to the height corresponding to the first layer of the material stack, the feeding mechanism moves the wood strips to the material receiving platform 2, and the discharging mechanism is used to convey the wood strips on the material receiving platform 2 to the wood strip processing equipment in sequence.

[0030] In this embodiment, if Figure 3, the frame 1 can be a vertically arranged rectangular frame, the lifting mechanism includes a first transmission wheel 3 and a second transmission wheel 4 arranged at the top and bottom of the frame 1; the first transmission wheel 3 and the second transmission wheel 4 are connected by a transmission belt 5; the first transmission wheel 3 and the second transmission wheel 4 can be arranged in two groups on both sides of the frame 1 in the horizontal direction, each group is connected by a transmission belt 5, the transmission belt 5 is connected with a vertical carriage 6, and the two groups of transmission mechanisms drive the vertical carriage 6 to move, which can improve the stability of its movement; the vertical carriage 6 drags the material receiving platform 2 to move. The vertical carriage 6 is slidably connected to the frame 1 and fixedly connected to the transmission belt 5, ensuring that the vertical carriage 6 is driven to move when the transmission belt 5 moves, and the vertical carriage 6 drags the material receiving platform 2 to move; and the vertical carriage 6 can be slidably connected to the frame 1 through a slide rail to improve the stability of the vertical carriage 6 movement.

[0031] The first transmission wheel 3 or the second transmission wheel 4 is connected to a power device such as a motor to drive the first transmission wheel 3 or the second transmission wheel 4 to rotate, thereby realizing the movement of the transmission belt 5. The power device can realize the up and down movement of the transmission belt 5 by forward and reverse rotation, thereby driving the vertical carriage 6 to move up and down. The vertical carriage 6 can drive the material receiving platform 2 to move up and down to the required height.

[0032] In this embodiment, if Figure 4 The feeding mechanism includes a horizontal carriage 7 slidably connected to the vertical carriage 6; a feeding scraper 8 is arranged at one end of the horizontal carriage 7 near the material stack 14; a belt 9 is arranged on the horizontal carriage 7, and the belt 9 is connected to a pulley 10 arranged on the vertical carriage 6; the horizontal carriage 7 can be slidably connected to the bottom of the vertical carriage 6, and the horizontal carriage 7 is located between the material receiving platform 2 and the vertical carriage 6; the two ends of the belt 9 can be fixedly connected to the two side areas of the upper surface of the horizontal carriage 7 respectively, and the belt 9 is transmission-connected with the pulley 10, and the pulley 10 is driven by an external power device such as a motor to move, and the pulley 10 drives the belt 9 to move, and the belt 9 can drive the horizontal carriage 7 to slide at the bottom of the vertical carriage 6, and the belt 9 moves along the feeding direction of the strips of wood, so that the horizontal carriage 7 can move the strips of wood to the material receiving platform 2; in this way, the automatic layered de-chopping of the material is realized, and there is no need for manual de-stacking, and there is no need to use loading and unloading devices such as gantry suction cup loaders.

[0033] When the material receiving platform 2 moves to the height corresponding to the material chop, the pulley 10 rotates in the direction close to the material chop, and the belt 9 will pull the horizontal slide 7 in the direction of the material chop to above the material chop. At this time, the lifting mechanism can control the material receiving platform 2 to descend a certain distance again, so that the feeding scraper 8 is against the end of the uppermost strip of wood on the material chop, reverse the pulley 10, and pull the horizontal slide 7 to move in the direction away from the material chop, and the feeding scraper 8 can scrape the uppermost strip of wood onto the material receiving platform 2.

[0034] When the feeding scraper 8 scrapes the uppermost layer of wood strips onto the receiving platform 2, the end stopper 15 on one side of the receiving platform 2 abuts against the wood strips of the second layer to prevent the wood strips of the second layer from being taken out together.

[0035] In this embodiment, if Figure 5 The discharging mechanism includes a plurality of third transmission wheels 11 arranged along the width direction of the material receiving platform 2; the plurality of third transmission wheels 11 are connected by a conveyor belt 12; a discharging scraper 13 is arranged on the conveyor belt 12; a plurality of third transmission wheels 11 can be evenly arranged along the width direction of the material receiving platform 2, and the plurality of third transmission wheels 11 are connected by a conveyor belt 12; the conveyor belt 12 is higher than the material receiving platform 2, and a plurality of discharging scrapers 13 are evenly arranged on the conveyor belt 12, one of the third transmission wheels 11 is connected to a power device such as a motor, so as to move the conveyor belt 12, and the conveyor belt 12 moves along the width direction of the wood strips, so that the discharging scraper 13 can push the wood strips on the material receiving platform 2 into the processing equipment one by one.

[0036] After the wood strips are transported to the receiving platform 2, the receiving platform 2 is moved to the same height as the processing equipment, and then the conveyor belt 12 moves along the width direction of the wood strips. Since a plurality of discharging scrapers 13 are provided on the conveyor belt 12, the conveyor belt 12 can move one circle to push all the wood strips on the receiving platform 2 into the processing equipment. Alternatively, according to usage requirements, the conveyor belt 12 can be moved for a certain distance to push some of the wood strips on the receiving platform 2 into the processing equipment one by one, thereby completing the automatic layered chopping and transportation of multiple layers of wood strips.

[0037] In this embodiment, a lifting detection switch is provided on the feeding mechanism. The detection switch can use a sensor. When the height of the material pile 14 changes, it senses the height information and transmits it to the lifting mechanism, so that the lifting mechanism can drive the material receiving platform 2 to stay at different heights; the signal receiving end of the power equipment that controls the lifting mechanism can be connected to the signal transmitting end of the sensor, thereby realizing the inductive control of the lifting mechanism.

[0038] Example 2

[0040] S1: placing the material receiving platform 2 next to the material stack 14, and the lifting mechanism moves to a specified height according to the position detected by the lifting detection switch;

[0041] S2: The end baffle plate 15 blocks the second layer of wood strips in the stack 14, and the feeding scraper 8 transports the wood strips in the first layer to the receiving platform 2;

[0042] S3: Move the material receiving platform 2 to the same height as the processing equipment, and push the wood strips on the material receiving platform 2 into the processing equipment using the discharging scraper 13, and determine the number of wood strips to be pushed in according to the requirements of the processing equipment.

[0043] By decomposing the entire process of multi-layer wood strip transportation into the above three steps, automatic chopping can be completed without manual handling, thereby reducing labor intensity. After chopping, different amounts of wood strips can be pushed into the processing equipment according to usage requirements, thereby adapting to different processing equipment.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
