The automatic board paving machine (CN208020439U) applied by the applicant discloses a technical scheme capable of realizing automatic splicing of battens into boards. Through more than one year of research, the technical scheme disclosed by the patent is not enough. Since the finished board needs to be substantially flush in four sides, a cutting device is provided at the entry end of the decking slot. When the battens 1 in the paving groove are fully paved in a row, the battens at the inlet of the paving groove are cut off by the cutting device. Therefore, the length of one batten 1 on one side of the conveying groove after being cut off is small, and even the length of the batten is smaller than the width of the paving groove, so that the batten in the groove is easy to be blocked due to deflection in the groove after the short batten enters the paving groove.

And, a plurality of vertically arranged sticks 1 are generally applied with glue at the same time. The glue brushing mechanism shown in fig. 5 and 6 can only realize glue coating on one side surface of the batten, and the glue box is arranged below the glue dropping roller, so that one part of the circumferential surface of the glue dropping roller is immersed in the glue box, and the glue brushing on two side surfaces of the batten can be realized simultaneously.

For example, two adjacent rollers are arranged on one side or one side, and the two rollers rotate inwards at the same time. The adhesive is guided between the two rubber rollers by adjusting the angle of the rubber baffle 13 or changing the position of the rubber box 15, so that the adhesive is coated on the rubber rollers.

As shown in fig. 7 to 9, in the technical scheme of this embodiment, the batten 1 firstly passes through the glue brushing mechanism and then enters the conveying groove 4 after being brushed by the glue brushing mechanism. The glue brushing mechanism shown in the embodiment adopts a pair of roller type vertically-arranged glue rollers, and the arrangement form of the glue rollers is shown in figure 4. The glue brushing mechanism is positioned on one side of the conveying groove 4, is arranged in parallel with the conveying groove 4, and comprises a material accommodating groove 21 and a manipulator conveying mechanism besides the glue roller 11. The rubber rollers 11 are positioned on two sides of the material accommodating groove 21, and the batten 1 is positioned in the material accommodating groove 21 after being brushed between the two rubber rollers 11 and then conveyed into the conveying groove 4 through the manipulator conveying mechanism. The manipulator transmission mechanism comprises a combined movement mechanism and clamping claws 22, and the clamping claws 22 are hinged to the combined movement mechanism and distributed left and right. The clamping claw 22 may be a rod-shaped structure with a protrusion or a hook at the lower part, one end is used for hinging, and the other end is used for clamping the side surface or the bottom end surface of the batten. Between the clamping jaws 22, which are distributed to the left and right, a cylinder 25 is provided, and a clamping force is provided by the movement of the cylinder 25. The movement pattern of the gripper jaw 22 according to the present solution is similar to the movement pattern of the pliers. Alternatively, one end of the clamping claw can be arranged on the combined motion mechanism through a sliding block, and the clamping claw is driven to translate through the actuating cylinder so as to provide clamping force. The above embodiments are only a few possible structural forms of the present invention, and the clamping movement forms in the prior art are all within the scope of the present invention, such as changing the arrangement form of the clamping jaws to clamp the upper and lower surfaces of the batten for transportation, etc. under the suggestion of this idea. In order to provide a sufficient movement space for the gripping claw 22, notches 19 are formed at positions on the side surfaces of the storage tank 21 and the transport tank 4 corresponding to the gripping claw 22.

In the embodiment shown in fig. 7 to 9, the combined movement mechanism is a slide block and a slide rod, and specifically includes a bracket 24 and a slide block 23, the bracket is supported around the conveying trough 4 and the material containing trough 21, the upper parts of the bracket are connected through a slide rod, and the slide block 23 is sleeved on the slide rod. Under the drive of an actuating mechanism, such as an actuating cylinder and the like, the sliding blocks can reciprocate above the material containing groove 21 and the conveying groove 4, and the structure provided with the clamping claws is fixed on the connecting rods of the two sliding blocks and can move up and down under the drive of the actuating mechanism. Therefore, the combined movement in two directions can be realized, and the function of conveying the battens is achieved.

As an alternative to a combined motion mechanism, another motion mechanism is provided as shown in fig. 10. The mechanism comprises a supporting plate 26, a swinging rod 28 and a pulley 29, wherein a limiting groove 27 is formed in the supporting plate 26, the limiting groove is arc-shaped, preferably circular arc-shaped, one end of the arc-shaped limiting groove is positioned above the material accommodating groove 21, and the other end of the arc-shaped limiting groove is positioned above the conveying groove 4. The pulleys 29 are positioned in the limiting groove 27, the supporting plates 26 can be a plurality of pulleys as required, and the pulleys 29 are connected through shafts. The gripper jaw 22 is directly or indirectly connected to a pulley 29, the movement path of which is parallel to the pulley. The swing lever 28 is a driving mechanism, and has a long groove, and the pulley 29 is located in the long groove. When a plurality of supporting plates are included, and the pulleys are connected through shafts, the shaft sleeves can be arranged in the long grooves. In this way, combined vertical and horizontal movements of the gripper jaw 22 can be achieved.

Besides, the battens after being brushed with the glue are conveyed to the conveying groove 4 through the manipulator conveying mechanism, and other alternative technical schemes are provided. As shown in fig. 11, the glue brushing mechanism corresponding to the mechanism is the horizontal glue roller disclosed in fig. 5 and 6. The conveying mechanism comprises a supporting table board 30, the supporting table board 30 is located at the rear end of the glue brushing mechanism and is arranged in parallel with the conveying groove, and the wood strips 1 after glue brushing are vertically arranged on the supporting table board, namely one side face of each wood strip faces upwards. The edge of the outer side below the supporting table surface is provided with an actuating cylinder, and the other side of the supporting table surface is hinged. Under the action of the actuating cylinder, the supporting table surface 30 turns inwards, the vertically arranged battens 1 slide into the conveying groove 4, and the end surfaces of the battens face upwards and are positioned in the conveying groove. As shown in fig. 12, another transmission scheme is disclosed. The corresponding glue brushing mechanism in the technical scheme is a vertically arranged glue roller, the conveying mechanism comprises a supporting table board 31 and a pushing mechanism 32, the glue roller 11 is positioned on two sides of the supporting table board 31 and arranged in parallel with the conveying groove, and the battens 1 after being brushed are positioned on the supporting table board to be flatly placed, namely one end face of each batten faces upwards. The pushing mechanism 32 is located on one side of the supporting table surface 31, and the battens brushed with the glue are pushed into the conveying groove through the pushing mechanism 32 on the supporting table surface. Conceivably, when the supporting table 31 is a conveyor belt moving to one side of the conveying groove, the conveying of the battens can be realized without arranging a pushing mechanism; similarly, when the supporting table 31 is a row of rollers rolling toward the conveying trough, the conveying of the battens can be realized without a pushing mechanism.

In order to improve the working efficiency of the equipment, a plurality of wood strips are generally brushed with glue at one time, that is, a plurality of wood strips are generally stacked in the conveying groove 4. As shown in fig. 7 and 8, in order to ensure the orderly delivery of the battens, a baffle 20 is arranged in the delivery chute 4, and the baffle 20 can be adjusted up and down by arranging a plurality of connection forms such as a kidney-shaped hole. Typically, the apparatus is a single block transfer, so the height of the baffle 20 from the bottom of the transfer chute 4 is greater than the thickness of one strip 1 and less than the thickness of two strips 1. In addition, because a plurality of battens are brushed with glue at one time, the problem that the battens are difficult to separate and cannot be conveyed because the adhesive is infiltrated between the end faces of the two battens often occurs. In order to solve the technical problem, a thumb wheel 16 is arranged on one side of the conveying groove 4, a tooth 17 is arranged on the thumb wheel 16, the thumb wheel 16 is hinged on the machine body through a connecting rod, and a tension spring 18 is arranged between the machine body and the connecting rod. The thumb wheel 16 rotates to the direction of transfer, and the height that tooth 17 apart from the transfer slot bottom is less than the thickness of a stuff to guarantee that tooth 17 can stir the side of the bottom stuff. The dial wheel 16 is a driving wheel and is driven by any power device. Meanwhile, in order to avoid the phenomenon that the conveying speed is higher than the linear speed of the rotation of the thumb wheel 16 to cause the conveying jamming of the wood strips, the thumb wheel 16 is specially selected to be a one-way ratchet wheel. In addition, the setting of thumb wheel 16 has still guaranteed the orderly transmission of stuff, and the upper place stuff just conveys behind the lower stuff promptly, has avoided because of the slope of upper place stuff a plurality of stuff crowd simultaneously to baffle 20 and cause the circumstances of jamming.

As shown in fig. 3, since the friction force of the wooden stick after being brushed with the glue is increased, a conveying mechanism is preferably installed at the bottom of the paving groove 6, and various forms including a conveyor belt, a roller and the like can be selected. The conveyer belt is selected to this embodiment, for the clearance problem of leaving over the adhesive on solving the conveyer belt working face, and this embodiment has fixed the scraper on the organism, and the cutting edge of scraper and the working face laminating of drive belt, the cutting edge of scraper was scraped to its working face when the conveyer belt rotated, clears up in real time promptly.

The paving mechanism further comprises a pushing mechanism 7, and the pushing mechanism 7 comprises a pushing plate 8. The bottom surface of the paving groove 6 is fixed, the height of the paving groove is the same as that of a working table surface 9 of the paving table, and the side surface of the paving groove 6 is connected with an actuating mechanism which moves up and down. The push plate 8 is arranged on one side of the paving groove 6, is slightly higher than the table top of the paving table and is approximately positioned at the half thickness of the batten 1. After the battens in the paving grooves 6 are paved, the actuating mechanism drives the side surfaces of the paving grooves to move upwards, and the push plates 12 push the battens to the working table surface 9 of the paving table. The up-and-down movement design of the side surface of the paving groove 6 skillfully solves the problem of pushing the wood strips after the wood strips are paved into a row and also solves the problem of clearing the wood strip clamp in the paving groove. As described above, the batten 1 used in the apparatus is a material for secondary utilization, and the problem of in-groove clamping is very easy to occur, which is almost unavoidable. The design greatly improves the operation efficiency of the equipment from the angle of being convenient for problem clearing. And, in order to guarantee that there is sufficient space when the card stagnation clearance in the groove, the promotion height of the side of the paving groove 6 can be designed into two grades, one grade is that the push pedal 8 passes through the height, and the other grade is the required clearance height when the card stagnation appears in the groove.

Since the finished plywood panel needs to be substantially flush on four sides, a cutting device, in this embodiment a circular saw 10, is provided at the entry end of the decking trough as shown in figure 3. When the battens 1 in the paving groove are fully paved in a row, the circular saw 10 starts to work and moves upwards under the driving of the actuating mechanism to cut off the battens at the inlet of the paving groove. Therefore, the length of one batten 1 on one side of the conveying groove after being cut off is small, and even the length of the batten is smaller than the width of the paving groove, so that the batten in the groove is easy to be blocked due to deflection in the groove after the short batten enters the paving groove. In order to solve the technical problem, a gap is particularly formed between the conveying groove 4 and the paving groove 6, and a batten length screening structure is arranged at the gap. As shown in fig. 13-17, the strip length screening mechanism includes a wheel 80 and a pressing plate 81, the pressing plate 81 is

The pressing plate is positioned above the gap between the conveying trough 4 and the paving trough 6 and spans the outlet end of the conveying trough 4 and the inlet end of the paving trough 6, namely one end of the pressing plate is positioned at the conveying troughThe other end of the circular saw is near the outlet, the other end of the circular saw is near the inlet of the paving groove, and the two ends of the circular saw are respectively positioned at two sides of the circular saw. The idler 80 is positioned between the conveying groove 4 and the paving groove 6; in this embodiment, the wheel 80 is fixed to the pressure plate 81 by a connecting member 85, and an actuator 82 is further connected to the upper side of the pressure plate 81. The connecting piece 85 is

And the wheel 80 is positioned between the gap between the conveying trough 4 and the paving trough 6 and is positioned below the pressing plate 81. In the conveying process of the batten 1, the upper circumferential surface of the third wheel 80 is coplanar with the bottom surfaces of the conveying groove 4 and the paving groove 6, so that the gap between the conveying groove 4 and the paving groove 6 is made up; when the circular saw 10 starts to work, the pressing plate 81 moves downwards under the action of the actuating cylinder, one end of the pressing plate compresses battens at the outlet of the conveying groove 4, the other end of the pressing plate compresses battens at the inlet of the paving groove 6, the idle wheel 80 also moves downwards, and battens which are not compressed by the pressing plate 81 above the gap between the conveying groove 4 and the paving groove 6 fall down from the gap. As an alternative, the wheel 80 may be replaced by a transition plate 87, as shown in figure 19, the transition plate 87 being hinged to the body at one end and connected to the ram at the other end. When the battens are normally conveyed, the upper surfaces of the transition plates 87 are coplanar with the bottom surfaces of the conveying grooves 4 and the paving grooves 6; when the circular saw 10 is started, the transition plate 87 is opened by the actuator cylinder.

In addition, in order to ensure that the battens which are not pressed by the pressing plate 81 above the gap between the conveying groove 4 and the paving groove 6 can be smoothly dropped from the gap. The spring 83 or other elastic devices are arranged below the pressing plate 81, the fixing modes of the other elastic devices can be adjusted at will and can be fixed on the side wall or the machine body of the pressing plate, and the elastic devices can be pressed downwards only when the circular saw 10 works. When the length of the wood strip meets the requirement that the wood strip is pressed by the pressing plate at the outlet end of the conveying groove, as shown in fig. 14, the elastic element contracts, and the wood strip is kept still. When the length of the wooden strip does not meet the requirement, namely the wooden strip is not pressed by the pressing plate 81, the wooden strip is forced to fall out of the gap under the action of the spring 83. As another embodiment of the compression device, the spring 83 may be replaced by an air nozzle 86 connected to a high pressure air source, as shown in FIG. 18. The air nozzle 86 can be fixed on the machine body, and a through hole is formed in the pressing plate 81 to sleeve the air nozzle 86. The air nozzle 86 can also be fixed to the pressure plate 81 and move up and down with the pressure plate 81.

One possible working process is as follows:

the equipment operator puts into between the opposition rubber roll 11 the stuff 1 that piles up from top to bottom, and stuff 1 moves to holding silo 21 rear end under the rubber roll effect, and gripper jaw 22 presss from both sides tight the bottom stuff side under the actuator cylinder drives, and transport mechanism drives gripper jaw upward movement earlier, then slider 23 moves to transfer chute 4 direction under the actuator mechanism drives, and after arriving transfer chute 4, gripper jaw 22 loosens, and the stuff that piles up falls into transfer chute 4. The side of the bottom batten 1 is stirred through the teeth 17 by the poking wheel 16, the bottom batten 1 is separated from other battens, the batten moves towards the paving groove 6 under the action of the conveyor belt 3, the batten located at the bottom is continuously stirred by the poking wheel 16, and the batten moves towards the paving groove 6 in order. After a row of battens are paved in the paving groove, the conveying groove and the conveying belt at the bottom of the paving groove stop working, the circular saw 10 starts working, the pressing plate 81 and the idle wheel 80 move downwards, one end of the pressing plate 81 compresses the end face of the batten at the outlet end of the conveying groove, the other end compresses the end face of the batten at the inlet end of the paving groove, the spring 83 compresses the battens below the pressing plate, and the battens which do not meet the length requirement fall down from the gap. After the battens are cut off, the side surfaces of the paving grooves are lifted upwards under the driving of the actuating mechanism, and the push plates 8 push the battens 1 arranged in rows to the working table surface 9 of the paving table under the driving of the actuating mechanism until the battens are spliced out.

The control of each action node can be realized by collecting signals through a sensor or a position switch and the like and then controlling the signals by a processor.
