Description

Flake Separation Device

technical field

The utility model relates to the technical field of automatic processing equipment, in particular to a sheet material separation device.

Background technique

The manufacturing process of sheet materials such as screens of electronic products is first to use a cutting machine to cut a large piece of glass sheet, and then finish it by a fine engraving machine, and then use a scanning machine to polish, fine carving and scanning processing are for manual work. The demand is too great, and the biggest difficulty in automatic loading and unloading is how to put the glass flakes into the processing equipment one by one for processing.

When using the cutting machine to cut the material, kerosene is often needed to protect the smooth cutting edge of the glass and the service life of the tool. Therefore, there will be kerosene on the opened glass. After stacking, the glass is not easily separated due to the kerosene. The glass flakes are stored in stacks. Therefore, in order to supply the automatic loading and unloading engraving machine for processing, the solution without kerosene is often used to sacrifice the life of the cutting tool to achieve the separation accuracy of the automatic loading and unloading.

When using the engraving machine for finishing, a large amount of cooling liquid is required for cooling, and the collected glass flakes are stacked and soaked in water. Since the glass flakes are wet, the glass flakes are adhered tightly and are extremely difficult to separate. This problem has always been the biggest problem hindering the use of automatic loading and unloading of engraving machines or scanning machines.

Most of the traditional separation schemes use a trough with an isolation groove to separate the sheets. However, due to the gap between the sheets in this trough with an isolation groove, it affects the entire trough. Storage capacity, but also need to manually put the sheet material into the isolation tank and then supply it to the subsequent processing machine for processing, which has low efficiency and high labor cost.

The device for separating and positioning the stacked glass sheets mentioned in the applicant's patent application No. 201821336633.X adopts the air flotation separation method, and uses compressed air to blow the side walls of the stacked glass sheets to make the glass sheets It is separated and floated, and then picked up by the robotic arm or the reclaiming mechanism piece by piece, and supplied to the equipment for processing. Although the problems existing in the existing isolation grooves are solved, this solution is more suitable for dry glass flakes. When the glass sheet is wet and the two sheets are closely adhered, relying solely on compressed air cannot ensure the success rate of separation, and once it cannot be ensured that only a single piece is separated and taken out each time, it will lead to poor processing. If it fails, the glass flakes are broken, and if they are not found in time during processing, a large amount of raw materials will be wasted, and the service life of the machine will also be affected.

Therefore, there is a need for a technical solution that can solve the effective separation of wet liquid sheets.

detailed description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1:

An embodiment of the present utility model provides a sheet material separation device, which is shown in FIG. 1 to FIG. The trough 2 is used to hold the sheets, and the sheets are stacked in the trough, and the stacking here may be either a horizontal stack in a vertical direction, or an upright arrangement in a horizontal direction. The lamination in this embodiment is a close-contact lamination of sheets and sheets, rather than an arrangement of isolation grooves. Therefore, there is no spacer groove in the trough in this embodiment, and the sheets are put into the trough. After that, a close arrangement can be formed, which greatly increases the capacity of the trough. The liquid spraying mechanism is a mechanism that can spray liquid outward. The liquid spraying mechanism 3 has a nozzle 31. The liquid spraying mechanism can apply a liquid flow to the flakes in the material trough through the nozzle, that is, a certain hydraulic pressure can be formed at the nozzle, and the liquid in the nozzle can be injected. The liquid is sprayed out.

The water tank is used to hold the liquid. In this embodiment, tap water may be used as the liquid. In other embodiments, the liquid may be conventional liquids such as pure water, seawater, or self-adjusting liquid used in industrial production. After the water tank is filled with water, it forms a submerged storage environment for the sheet material. On the one hand, it can wet the sheet material, which is very suitable for processing in a wet environment, especially in a processing environment that requires cooling liquid or lubricating liquid; on the other hand, it can further keep the sheet material. material cleaning.

The trough 2 is placed in the water tank 1 and the nozzle is also deep into the water tank, so that the nozzle is immersed in the liquid to apply a liquid flow to the side wall of the sheet material in the trough. The liquid flow is applied to the gap between the sheet and the adjacent sheet, but because the gap between the two sheets is extremely small, the nozzle must apply a liquid flow to the side wall of the sheet, and the liquid flow penetrates into the two sheets from the side wall of the sheet. The flakes are separated in the gap. Since the nozzle is also placed under the liquid level of the water tank, the liquid flow formed at the nozzle is applied to the sheet material in the trough, specifically the side wall of the laminated sheet material, and the liquid flow will further Penetrates from the tiny gap between the two sheets to achieve effective separation of the two sheets.

In other embodiments, the nozzle may not be immersed under the liquid surface of the water tank, and the nozzle may be arranged above the water tank to spray the side wall of the flakes to apply liquid flow, which can also eliminate the problem of liquid adhesion between the two flakes .

In this embodiment, after the two adjacent sheets are separated by the liquid flow, they are taken out by the manipulator, and the two adjacent sheets at the next adjacent position are again pressured by the liquid flow of the nozzle to be effectively separated, and so on and so forth until the trough All flakes inside are separated and removed.

In order to ensure the relative movement between the nozzle and the sheets in the trough, so that the sheets are taken out in an orderly manner, the driving mechanism 4 is used in this embodiment to drive the trough to move. The movement is relative, and the trough moves relative to the nozzle. Yes, the nozzle is fixed and stationary relative to the water tank, so in other embodiments, the driving mechanism may drive the nozzle to move, while the material trough is fixed and stationary relative to the water tank. That is, if the nozzle is fixed relative to the water tank, the drive mechanism drives the trough to move relative to the nozzle along the track; if the trough is fixed relative to the water tank, the drive mechanism drives the nozzle to move relative to the trough along the track. The nozzle is fixedly installed relative to the water tank, not necessarily the nozzle is fixedly installed on the water tank, but also the nozzle is installed on the mounting bracket. The mounting bracket may be independent of the water tank, as long as the nozzle is stationary relative to the water tank.

As far as sheets are concerned, rectangular sheets have front and back sides and four sides (side walls). As mentioned above, the stacking of sheets in the trough can be vertical stacking (one on top of the other) or It is a horizontal and vertical arrangement (when squared, a certain side is used as the axis of rotation to turn 90 degrees to stand, and a vertical arrangement means that one piece overlaps with the front and back of the other piece). The stacking direction of the sheet material is also the advancing direction of the sheet material relative to the nozzle (relative to move). For example, in this embodiment, the flakes are placed in the trough according to Fig. 1 and are arranged in the horizontal front-rear direction.

In order to facilitate the reader to better understand the technical solution in this embodiment, a direction definition is made for this purpose, with reference to the perspective view of the sheet material separation device in FIG. Top view), that is, as the up and down direction, which is also the up and down direction of the device, also known as vertical (Z axis); the left and right directions on the reader's perspective on the paper are the left and right directions close to the device itself, also known as horizontal (X axis); readers The up-down direction on the viewing angle paper is the front and rear direction of the device itself, the lower part is the front of the device, that is, the end of the trough away from the nozzle is the front end, and the upper part is the rear of the device, also called the longitudinal direction (Y-axis). It can be understood that the above definition of direction is used as a reference in this embodiment. If the reading environment or scene changes, corresponding adjustments are made, and the definition of direction is not regarded as a limitation on the protection scope.

Since the stacking direction of the sheets in this embodiment is in the front-rear direction, the driving mechanism 4 also drives the trough to move in the front-rear direction. In other embodiments, if the stacking direction of the sheets is vertical, the driving mechanism can also be transformed to drive the trough to move vertically, and the trough will move up or down in the water tank, and the nozzles are fixed. It can be installed in the water tank corresponding to the trough. The so-called corresponding installation means that the nozzle installation position can make the water spray hole apply liquid flow to the side wall of the laminated sheet material in the trough. The existing installation method is used to complete, and if there is a special structure installation in this embodiment, it will be described in detail in the following content.

In this embodiment, the driving mechanism 4 includes a rail 41 arranged along the sheet stacking direction (that is, the front-rear direction/X-axis direction in FIG. 1 ), a sliding block 42 for carrying the trough 2 and a sliding block 42 for driving the sliding block 42 along the The drive assembly that moves along the track 41. The drive mode with track can ensure the smooth operation of the trough. In order to control the moving distance of the material trough more accurately, in this embodiment, the driver assembly includes a drive motor 43 and a lead screw 431 , the slider 42 is provided with a bearing sleeve 432 matched with the lead screw, and the drive motor 43 drives the lead screw 431 to rotate to make The slider 42 moves along the rail 41 . In this embodiment, the lower part of the water tank 1 is used as the placement space for the driving mechanism, and a base 40 is provided at the lower part of the water tank 1 , and the base 40 has front and rear baffles 401 , which can support and fix the water tank. For the left and right sides of the base, the telescopic protective cover 402 is used for installation. One end of the telescopic protective cover in the front-rear direction is connected to the front or rear baffle 401 of the base, and the other end is connected to the slider. The end cover is connected to the base, so that the entire driving mechanism can be sealed and protected to prevent liquid or dust from falling in, thereby effectively increasing the service life of the driving mechanism.

In this embodiment, the material trough is fixedly installed relative to the driving mechanism through the 2-pass material rack 22, that is to say, the material rack is fixed on the slider of the driving mechanism, and three material troughs are arranged side by side in the material rack 22, and each material trough has two There are nozzles on the sides.

In this embodiment, the material trough adopts a special structure. The material trough 2 is provided with a clamping column 23, and the corresponding position on the material rack 22 is provided with a matching clamping groove 24 for the material tank to be detachably installed on the material rack.

The trough 2 includes a bottom plate, front and rear backing plates extending upward at the front and rear ends of the bottom plate, and clamping posts 23 are arranged on both the front and rear backing plates. The front plate is bent forward to form a handle portion 25, which is convenient for the operator to pick and place. The backrest plate is bent backwards and then bent back at the rear end to form the abutting quick positioning portion 26. When placing the trough, the operator will first tilt the abutting quick positioning portion downward against the material rack, and the end portion of the The back bend forms a smooth arc surface, which is conducive to the rapid placing of the material trough into the material rack. The left and right baffles 27 are arranged on the left and right sides of the bottom plate, and the left and right baffles 27 are respectively installed on the front and rear backboards, wherein two ends of one of the left and right baffles and the front and rear backboards are designed with adjustment long holes 28 and adjustment columns. Adjustable structure, for example, the two ends of the left baffle are provided with adjustment long holes, and the front and rear backboards are provided with bolts, so as to adjust the width of the trough to adapt to different sheet sizes. An abutment surface 21 inclined forward from bottom to top is provided on the front backboard to ensure the inclined placement of the sheets.

It can be understood that the so-called driving mechanism drives the trough to move relative to the nozzle, which may be that the driving mechanism drives the movement of the entire trough, or the driving mechanism drives some components of the trough to move. In other embodiments, there may be other specially designed troughs. For example, for horizontally stacked troughs, the trough has left and right baffles, and at least the front plate (abutting against the last sheet) and the bottom plate can be relatively movable. , then the way the driving mechanism drives the trough is to drive the bottom plate of the trough, and the left and right baffles of the trough may not be driven, which can also make the sheet material move relative to the nozzle. For the vertically stacked trough, there are baffles around the trough, and the bottom plate of the trough is movable, so the way the driving mechanism drives the trough is to drive the bottom plate of the trough to move vertically, and the baffles around the trough can be different. driven. The base plate can be a support plate or a support bar. The flakes themselves should remain relatively stationary with the trough, at least the flakes themselves and a certain part of the trough remain relatively static, if the flakes move relative to the trough, the flakes will be scratched, so the driving trough is the driving piece. material movement. It is just not necessary for the entire trough to move, but only a certain element in the trough can push the flakes to move.

In other embodiments, a clip slot is provided on the material trough, and a clip column is arranged on the material rack, which is a conventional alternative technical means.

In another embodiment, the driver assembly includes a drive motor, a driving pulley, a driven pulley and a conveying belt, a conveying belt is sleeved between the driving pulley and the driven pulley, the slider is fixed on the conveying belt, and the driving motor drives the driving pulley to rotate to drive the The slider moves on the track. It is feasible to move the slider through the structure of the conveyor belt, and the cost is low.

It can be understood that the nozzle can use the existing nozzle structure, and the device can not be provided with a pump body during production, but in the actual application scenario, the existing pump body can be sleeved on the nozzle of the device to realize plug-in. Ready-to-use structure, simple and convenient. For example, in the absence of a pump body, a faucet with a valve can be connected to the nozzle through a water pipe, and the high-level potential energy water pressure can provide hydraulic pressure to the nozzle to apply liquid flow to the flakes in the trough.

In order to adapt to more processing scenarios, including small and independent processing machines, the liquid spray mechanism 3 in this embodiment further includes a pump body 32 and a pipeline 33 connecting the pump body 32 and the nozzle. The pump body is a water pump, which can extract water from the water source and supply it into the water tank. In order to facilitate production, simplify the structure, and form a green and environmental protection mode that can be recycled, in this embodiment, the pump body 32 is also connected with a liquid storage tank 34 for supplying liquid to the liquid spraying mechanism. In another embodiment, the pump body not only supplies liquid to the liquid spraying mechanism, but also supplies liquid to the water tank. Especially during the initial operation, the water tank must be filled with water first, and a bucket can be used to fill the water tank with liquid. In the method of supplying liquid from the body to the liquid spraying mechanism, due to the limited flow of the nozzle, it takes a long time to fill the water tank with water. At this time, in order to improve the automation and ensure the efficiency, the water tank 1 has a liquid filling port 11, and the pump body extracts and stores the liquid. The liquid in the liquid silo 34 is injected into the water tank through the liquid filling port 11. The realization method can be achieved by adding a three-way valve to the pipeline. During the initial operation, the three-way valve connects the pump body and the liquid filling port of the water tank, so the liquid will not It enters the water tank through the nozzle, but is poured into the water tank in large quantities through the filling port. The time for filling the water tank will be significantly shortened and the efficiency will be improved. Of course, a special pump body and pipeline can also be added to extract the liquid in the liquid storage tank and inject it into the water tank through the filling port. The water tank 1 has an overflow port 12 , and the liquid in the water tank 1 is returned to the liquid storage tank 34 through the overflow port 12 , forming an eco-friendly mode of recycling. If the overflow liquid in the water tank does not need to be returned to the liquid storage tank in large processing occasions or other occasions, the overflow liquid in the overflow port can be returned to other holding spaces, such as water channels, buckets, etc. The liquid storage tank is a water storage container, which can be a separate container, or a water tank set on the machine table, or a water storage tank set up elsewhere from the machine.

In the case of high-efficiency processing, the sheet separation device can have more than two water tanks to form a multi-line operation, and each water tank is equipped with a trough to meet the use of large-capacity feeding equipment. There is a water receiving tank under the water tank, the liquid in the water tank flows into the water receiving tank through the overflow port for collection, and a drain pipe is arranged at the lower part of the water receiving tank to return the liquid in the water receiving tank to the liquid storage tank or other accommodation space. Here, more than two water tanks can be placed in one water receiving tank, which is conducive to the unified return of overflowing liquid. Of course, one water tank can be set with one water receiving tank. Each water tank may have more than two overflow ports or overflow pipes. However, only one drain pipe for the sink can be provided, and of course more than two can be provided.

For the pipeline design, this embodiment adopts a simple structure, with low cost, small space occupation, and good effect. The pipeline 33 includes a hollow tube 331 arranged along the width direction of the trough (the left-right direction of the device). The hollow tube 331 Two or more liquid outlets 332 are arranged on the side wall of the hollow tube along the axial direction of the hollow tube (that is, the left and right directions of the device). For the case where only one nozzle is available, the other liquid outlets can be blocked, leaving only one The liquid outlet, the two ends of the hollow pipe 331 are provided with liquid inlets 333, the liquid inlet 333 is connected to the pump body through a connecting pipe (the dotted line in the figure indicates that the connecting pipe is hidden), and the liquid outlet passes through the connecting pipe (Fig. The dashed lines indicate that the connecting pipes are omitted) and are respectively connected to the corresponding nozzles 31 . Injecting liquid from both ends of the hollow pipe can ensure more stable hydraulic pressure and smoother output. Of course, in other embodiments, the hollow tube may be provided with a liquid inlet port only at one end, or a liquid inlet port may be provided on the side wall of the hollow tube, which can also achieve the liquid inlet effect.

The liquid spraying mechanism 3 also includes a mounting bracket 30. There is a space through which the material trough can pass through between the mounting bracket 30 and the water tank wall. For example, in this embodiment, the mounting bracket and the bottom wall of the water tank leave a space between the mounting bracket and the bottom wall of the water tank so that the material tank can pass through. , if the sheets are stacked vertically, the space between the mounting frame and the side wall of the water tank can be reserved. Such a combination of space before and after can maximize space utilization, reduce space occupancy, and clean surface pipelines without causing messy pipelines. The mounting frame is a carrier that ensures the combination of the liquid spraying mechanism and the device, and the mounting frame can be complex or simple. The mounting frame in this embodiment is a plate-like structure, which occupies less space and is easy to install. Of course, it is not excluded that in other embodiments, the mounting frame may be composed of several brackets, or a smaller fixing piece may be used to fix the nozzle. The smaller fixing piece should also be regarded as a mounting frame. The mounting frame may be an integral structure, or it may be It is several small parts that work together to form the mount. Of course, in the case of a single trough, the nozzle is made of a metal shaped tube and the mounting bracket is omitted. In short, the installation method of the nozzle on the mounting frame should be set towards the storage space in the trough (that is, towards the corresponding sheet material in the trough) and avoid the trajectory of relative movement with the trough, that is to say, the nozzle cannot block the movement of the trough. , the nozzle can partially extend into the trough, but as long as it does not affect the movement of the sheets in the trough, of course, the nozzle has the function of limiting the sheet material except for the parts.

In this embodiment, in order to further improve the processing efficiency, the number of troughs is set to three, and two nozzles 31 are respectively provided on the mounting frame 30 corresponding to the two sides of each trough 2 . Each trough corresponds to two nozzles, which is conducive to the more balanced separation of flakes. In special cases, if the trough is only provided with nozzles on one side, the effect of flake separation can of course also be achieved, but due to the unilateral Nozzle setting can easily lead to sheet tilting and affect separation accuracy. In other embodiments, according to the needs of processing and production, the minimum number of troughs may be set to one, or two or four or more, and the corresponding nozzles may be appropriately reduced or increased.

In other embodiments, at least two nozzles form a set and are disposed relative to at least two side walls of the corresponding flakes in the chute. That is to say, the two nozzles as a group do not have to be arranged on opposite sides of the trough, but can also be adjacent to each other. For example, nozzles are provided on the left and bottom sides of the trough, which can also effectively and accurately separate the flakes. Effect.

In order to adapt to sheets of different sizes and enhance the adaptability of the device, the nozzles are installed on the mounting frame in an adjustable spacing manner to adjust the distance between the two nozzles on both sides of the trough: on the mounting frame 30 along the width direction of the trough The protruding strips 35 are provided, and the nozzle 31 is provided with a slot 311 matching the protruding strip. The nozzle 31 is installed on the protruding strip 35 of the mounting frame through the slot 311 and can slide in the width direction of the trough (the left and right direction of the device). The slot and the protruding strip can be fixed by interference fit, or can be fixed by bolt locking.

In other embodiments, elongated holes/arrangement holes may be arranged on the mounting frame along the width direction of the trough, and projections matching the elongated holes/arrangement holes may be arranged on the nozzles, and the nozzles may be installed on the length of the installation frame through the projections. In the strip hole/arrangement hole and can slide/change position in the width direction of the trough. The protruding block can slide in the elongated hole to change its position, and can be directly embedded in the case of interference fit, or a bolt and a nut can be arranged on the protruding block to lock the protruding block in the elongated hole. As an alternative to the long holes, the holes arranged in the left and right directions are used, that is, a plurality of holes are arranged at a certain interval, and the intervals between the nozzles defined by each hole are different, so as to adapt to sheets of different sizes.

When the sheet material is progressively sent to the nozzle one by one, as long as the accuracy of the advancing distance is controlled, the sheet material entering the liquid flow application area of the nozzle will be separated by itself. At this time, the manipulator will take the separated sheet in time. material can be. In this embodiment, in order to prevent errors, a stopper is set in the trough at a position near the rear of the nozzle. When the trough moves forward, the sheet material will be limited when it reaches the position of the stopper, and the sheet material stopper will limit the position. In a specific position, since the stopper is set near the nozzle, the sheet material will be separated by the liquid flow of the nozzle, and after separation, it will be precisely limited by the stopper, so that the manipulator can take it out accurately. Specifically, a stopper 312 extending from the nozzle 31 into the material trough 2 is used to stop the first piece of sheet material beside the water spray hole of the nozzle in the direction of relative movement of the sheet material. The so-called first piece of material is the last piece of material in the front-rear direction (and also the closest to the nozzle). In this embodiment, the nozzle 31 is extended toward the side of the corresponding trough (the nozzle is outside the trough, so the nozzle is extended to the inside of the trough). The stopper, the front surface of the stopper 312 and the side wall of the trough 2 form a right-angle positioning structure, which further ensures that the sheets will not be inclined or dislocated after separation. In other embodiments, the stopper can also be arranged on the mounting frame instead of the nozzle, as long as it can ensure that there is a stopper near the rear side of the nozzle in the trough, if the stopper is too far from the nozzle Then the limit effect will not be achieved. If it is too close, it will easily interfere with the liquid flow of the nozzle and cause the failure of sheet separation. Therefore, it is advisable for the stopper to be within a distance of 1 to 2 sheet thickness behind the nozzle.

Since the stopper may protrude into the trough to stop the sheet material, if the stopper is fixed, the pick and place of the trough will be restricted. During processing, the trough can only be pushed and pulled back and forth. Pulling it back to the original position, and then putting the sheet material into the trough, will greatly affect the processing efficiency, or at least taking out the trough will bump the stopper. In order to ensure the processing efficiency, further improvements are made in this embodiment. The front end of the mounting frame 30 is rotatably mounted with a flip frame 301 , the nozzle 31 is installed on the flip frame 301 , the stopper 312 is installed on the nozzle, and the stopper 312 Extending down to the bottom of the trough is used to limit the turning angle of the turning frame when the turning frame is turned to the side of the feeding trough. It can be quickly positioned and processed directly. The turning stopper 313 can be integrally formed with the stopper, or it can be installed on the nozzle separately, or the turning limiter 313 can be independently installed on the turning frame. In other embodiments, in the case of having a turning frame, the stopper can also be directly arranged on the turning frame, and does not necessarily need to be fixed on the nozzle. When the processing is completed (the sheets are all taken out), the turning frame is turned upside down, and a large space will be vacated at the front of the water tank, which is convenient for the quick removal and replacement of the material trough.

It can be seen that, in order to avoid the existence of the installation frame, the material trough will bump into the installation frame when it is taken and placed from the water tank, the installation frame can be specially designed, just like the structural design of the flip frame before the installation frame. , the flip frame is flipped backwards to free up space for the larger trough to be taken out or put into the water tank. In other embodiments, the installation frame can be further designed, for example, the installation frame includes a front frame for installing the nozzle and a rear frame for installing the front frame, the rear frame is fixedly installed relative to the water tank, and the front frame can be fixed relative to the rear frame. Flip installation or push-pull overlapping installation of the front frame relative to the rear frame is used to shrink the space of the front frame and obtain more space when the trough is taken out of the water tank. For the flip structure, in fact, the front frame is equivalent to a flip frame, and the front frame and the rear frame can be flipped by pivoting installation; The frame can be slid, and the front frame can be pushed back to overlap the rear frame, which also greatly reduces the space occupied by the front frame. Pipes and other components can be installed on the rear frame. If the pipeline is on the upper surface of the rear frame, the front frame will pass through the lower surface of the rear frame when the front frame is pushed and pulled. The rear rack can even be just a sliding rail, as long as the front rack can be mounted on it.

In this embodiment, a special structural design is adopted for the nozzle. The nozzle 31 includes a nozzle body 313 with a water channel channel and a seat body 314 for fixing the nozzle body. The nozzle body 313 is respectively provided with water spray holes 315 and The water inlet 316 and the mouth body 313 are installed on the mounting frame 30 (specifically, the turning frame 301 ) through the seat body 314; The first piece of material is stopped by the stopper 312 beside the water spray hole of the nozzle, and the nozzle body 31 is provided with two or more water spray holes 315 arranged along the direction of the side wall of the piece material on the side of the nozzle body 31 facing the corresponding material trough 2 . For example, if the side wall of the sheet material is in the up and down direction, the water spray holes are also arranged in the up and down direction, that is, a plurality of water spray holes are arranged from top to bottom (or from bottom to top). Yes, the sheet material can be obtained in the up and down direction of the side wall. Flow influence on a line, rather than a point, enhances flow influence. To this end, the arrangement of a plurality of water spray holes can also be replaced by narrow and long water spray holes. In this embodiment, two upper and lower water spray holes are shown, but in other embodiments, three or more water spray holes may be provided.

It can be seen from the figure that the nozzle body of the nozzle in this embodiment is plate-shaped, the seat body is also plate-shaped, and the stopper is also a plate device. One side has water spray holes, the water spray holes are long holes with width in the front and rear directions, the number of water spray holes is more than two, and the water spray holes are arranged along the side wall of the sheet, that is, along the upper and lower directions. The mouth body, the seat body and the stopper are combined and installed, the structure is simple, and it is easy to disassemble and assemble. The side of the mouth body facing the corresponding trough is provided with a stepped surface, the stopper is installed on the stepped surface to form a right angle with the mouth body, and the mouth body is locked on the seat body by screws.

In order to prevent the problem of failure of sheet separation when the water spray hole of the nozzle is just facing the side wall of the sheet. In this embodiment, two sides of the material trough are respectively provided with nozzles, and the nozzles are provided with long and narrow water spray holes or two or more water spray holes are arranged with reference to the direction along the side wall of the sheet material. The arrangement of two or more water spray holes and the two water spray holes at least form wide strip holes with a certain width extending parallel to the lamination direction of the sheets at both ends. The so-called side wall direction of the sheet material means that the side wall of the sheet material to which the nozzle is aligned is equivalent to a line. If the sheet material is stacked horizontally as shown in the drawings of this embodiment, the line of the side wall of the sheet material is in the up and down direction. The sheet material is stacked up and down in the stacking direction, and the line of the side wall of the sheet material is horizontal or horizontal.

As shown in the drawings in this embodiment, nozzles 31 are respectively provided on both sides of the trough 2, and the nozzles 31 are set with reference to the direction from the bottom of the trough to the top of the trough (the up-down direction in this embodiment). Arrange more than two water spray holes 315, and the spray holes near the top of the trough (the upper spray holes) are wider in the sheet stacking direction (front and rear direction) than the water spray holes near the bottom of the trough (the lower spray holes). water hole) width in the sheet stacking direction (front-to-rear direction). That is to say, the water spray hole also has a width in the front and rear directions, which is defined as a wide strip hole, so that the liquid flow of the wide strip hole of the water spray hole will form a line instead of a point in the front and rear direction. The pressure range of the water hole can correspond to a thickness range of sheet material larger than one sheet. In this embodiment, the width of the upper water spray hole is larger than that of the lower water spray port, in order to adapt to the feeding habit. In practice, the sheets stacked into the material frame are not completely perpendicular to the bottom wall of the material frame. , but it will be slightly tilted back (forward in the direction of the device), then the upper water spray hole has a larger width, the upper part of the sheet will receive greater hydraulic pressure, and the sheet will float forward (the device direction backward) has a greater magnitude so that it ends up being completely perpendicular to the bottom wall of the trough.

In order to further immobilize the placement of the flakes, in this embodiment, the end of the trough 2 away from the nozzle (the front end of the trough) is provided with an abutment surface 21 that gradually slopes away from the nozzle from the bottom of the trough to the top of the trough (from the bottom to the bottom of the trough). The top-up and forward-inclined abutment surface) is used to put the sheet material into the trough and place it at a certain angle backward inclined (forward of the device). In this way, the special design of the different widths of the upper and lower water spray holes in this embodiment can be perfectly matched. For the trough in which the sheets are stacked vertically in other embodiments, the abutting surface is provided at the bottom of the trough, and one end of the abutting surface is higher than the other end to form an inclined abutting surface.

In this embodiment, a reclaiming robot 5 is provided for the sheet material separation device to form a material reclaiming device. The material reclaiming robot 5 has a pick-and-place portion 51 for sucking the sheet material, and then sucks the separated sheet material 9 in the material trough. The reclaiming manipulator has a rotating rod and a Y-axis drive and a Z-axis drive, which enables the pick-and-place part to efficiently pick up the sheets and place them in the designated position. In other embodiments, the pick-and-place manipulator can be equipped with XYZ-axis three-axis drive to cover a wider range of activity trajectories. The pick-and-place part in other robots can be a mechanical gripper, which is used to pick up sheets, especially some sheets with hollow surfaces.

The working steps and principle of the reclaiming device in this embodiment are as follows: firstly, the flakes are fully loaded into the trough and the trough is put into the water tank, and then the water tank is filled with water, the liquid spray mechanism starts to work, and the nozzle starts to work. The liquid flow is sprayed out, and the driving mechanism drives the trough to start to move. When the first piece of material in the trough is located at the water spray hole of the nozzle, the first piece of material and the adjacent piece of material are placed under the water level of the water tank, and the water pressure is balanced. The adhesive force disappears below, and the liquid flow from the water spray hole will enter the gap between the two pieces of material to separate the two pieces of material smoothly. For the first piece of material, the driving mechanism continues to advance the trough, so that the current first piece of material is located at the water spray hole of the nozzle, and so on and so forth.

Embodiment 2:

The sheet material picking and placing device in this embodiment is the same in principle as the sheet material separating device in the above-mentioned embodiment 1, the difference is that: in this embodiment, the driving mechanism is used to drive the nozzle so that the nozzle and the material rack are separated from each other. The relative movement occurs along the sheet stacking direction, that is to say, the trough is fixedly installed relative to the water tank, the nozzle is installed on the driving mechanism through the mounting frame, and the driving mechanism drives the nozzle to move relative to the trough along the sheet stacking direction.

For other structural components of the sheet material separating device in this embodiment, reference can be made to the description in the above-mentioned Embodiment 1, and details are not repeated here.

Embodiment 3:

In this embodiment, the moving direction between the nozzle and the trough is the horizontal direction, that is to say, the flakes are arranged upright in the trough. As shown in FIG. 5 , the trough is moved relative to the water tank. Yes, when the material trough is put into the water tank, the water tank will set a certain avoidance space for the movement of the material trough, that is to say, when the material is taken out, the material trough is located on one side of the water tank, and the other side of the water tank is an avoidance space, so that The trough can move from one side of the water tank to the other side, and the side mentioned here is not necessarily the end of the trough abutting against the water tank, it is allowed to not abut the end of the water tank. Due to the need for avoidance space, the length of the water tank in the direction of the movement of the trough is greater than the length of the trough, that is to say, the water tank is provided with an avoidance space in the direction of the relative movement of the trough, and the water tank is used to avoid the relative movement of the trough. A material box for accommodating the processed sheet material is arranged above the set avoidance space. Processed means to include sheets that have been separated from laminated sheets, or processed sheets that have been processed by a processing machine. The material-forming box may have a slot for placing the processed sheets in separate layers, and the material-forming box may also be an accommodating box to directly stack the sheets.

Since the finished material box is arranged above the avoidance space of the water tank, on the one hand, it will not block the reclaiming space of the material trough, and on the other hand, it can effectively use the repeated space on the water tank. The upper part is the avoidance space of the material trough. Above the avoidance space, there is a mounting frame for installing the nozzle. Then the mounting frame can be set as a material box, so that the mounting frame and the material box can overlap vertically to utilize a space, effectively The limited space of the device is utilized, especially when the material box has a slot for separating and arranging the processed sheets into layers, and the reclaiming manipulator in the above-mentioned embodiment can form a sheet material separating insert. The reclaiming manipulator can insert the laminated sheet material in the material trough into the slot of the material box, so that the sheet material can be directly changed into the inserted rack material after separation, which makes the subsequent process easy to use.

It can be understood that it is the best solution to place the finished material box above the avoidance space of the water tank. If the finished material box is arranged around the water tank, a sheet material separation and insertion machine can also be formed.

For the device in which the trough is stationary relative to the water tank and the nozzle moves relative to the trough, the above-mentioned setting of the material box can also be made.

Embodiment 4:

This embodiment and the above-mentioned embodiment 3 both provide a device for adding a material box. The corresponding structure can refer to the above-mentioned embodiment 3. The difference is that in this embodiment, the relative movement direction between the nozzle and the material trough is vertical ( Z-axis direction), that is to say, the sheets are stacked horizontally in the trough, the trough moves relative to the water tank, and a certain avoidance space will be set for the movement of the trough above the water tank, but if the above example 3 In this way, it is not conducive to reclaiming the material by setting the material box above the water tank. Therefore, for this kind of material trough, the relative movement direction is vertical, and the driving mechanism will be set beside the water tank, so consider setting the material box above the driving mechanism. This can make full use of the limited installation space.
