Description

Technical Field

[0001] The present invention belongs to the technical field of plywood production equipment, and particularly relates to a semi-automatic plywood finished product grading and stacking machine. Background Art

[0002] The last process in plywood production is to repair, grade, and pack the finished boards. Currently, most of this process is completed manually. The working scenario is as follows: Every two workers form a group. They observe, repair, and judge the grade of each side of each board in the finished boards, and then stack, pack, and store the finished boards of different grades.

[0003] The weight of each board of plywood products (ordinary specifications) is about 30 kg. Workers carry each board up and down, turn the front side to the back side manually for 8 hours a day, repair and judge the grade at the same time, and then stack the boards according to different grades (the height of the board stack is about 1.6 meters). Immediately afterwards, they pack and store the boards. It goes without saying that the labor intensity is extremely high. As a result, it is very difficult to recruit workers for this position at present. Therefore, enterprises have to significantly increase the wage for this position to barely maintain production. However, the problems that still cannot be solved are as follows: The quality of manual grading, stacking, and packing is poor, the edges and corners of the board stack are uneven, and downstream customers are not satisfied; moreover, the work efficiency is extremely low. Two workers cannot sort many boards and make few packages in a day, so the production cost is high. Enterprises hope that there can be a machine to replace the current manual grading, stacking, and packing work, reduce the labor intensity of workers, and improve production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an economical and practical semi-automatic plywood finished product grading and stacking machine for enterprises, so as to reduce the labor intensity of workers and improve the efficiency of product grading and stacking.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A semi-automatic plywood finished product grading and stacking machine includes an automatic board loading mechanism, a front repair and grading mechanism, a single-sided B board stacking mechanism, a single / double-sided C board stacking mechanism, a board turning mechanism, a back repair and grading mechanism, a double-sided B board stacking mechanism, a double-sided C board stacking mechanism, and a single / double-sided A board stacking mechanism, which are arranged and installed in sequence;

[0007] The automatic board loading mechanism is used to feed the plywood to be repaired and graded into the front repair and grading mechanism;

[0008] The front repair and grading mechanism is used to repair and grade the front side of the plywood to be repaired and graded, and control the working state of the subsequent mechanisms according to the front grading result;

[0009] The single-sided B board stacking mechanism is used to collect and transfer the single-sided boards with a qualified front grading result;

[0010] The single / double-sided C-board stacking mechanism is used to collect and transfer single-sided boards and double-sided boards that are defective according to the front-side grading results.

[0011] The board flipping mechanism is used to flip double-sided boards with qualified front-side grading results or single-sided and double-sided boards with excellent front-side grading results and send them into the reverse repair and grading mechanism.

[0012] The reverse repair and grading mechanism is used to perform reverse repair and grading on the plywood sent by the board flipping mechanism and control the working states of the subsequent double-sided B-board stacking mechanism, double-sided C-board stacking mechanism, and single / double-sided A-board stacking mechanism according to the reverse grading results.

[0013] The double-sided B-board stacking mechanism is used to collect and transfer double-sided boards with qualified reverse grading results.

[0014] The double-sided C-board stacking mechanism is used to collect and transfer double-sided boards that are defective according to the reverse grading results.

[0015] The single / double-sided A-board stacking mechanism is used to collect and transfer single-sided boards with excellent front-side grading results and double-sided boards with both excellent front-side and reverse grading results.

[0016] To better understand the technical solution of the present invention, the explanations of some names are as follows:

[0017] "Single-sided board" - a board that is processed and inspected on only one side according to quality standards, and no strict quality requirements are imposed on the other side. "Double-sided board" - a board whose both sides are required to be processed and inspected according to the same quality standards. "Front side and reverse side" - respectively refer to the current side and the other side of the board. "A-board" - refers to an excellent board; "B-board" - refers to a qualified board; "C-board" - refers to a defective board. For example: 1) "Double-sided B-board" refers to the qualified product of a double-sided board (both the front and back sides are judged as qualified products, or one side is a qualified product and the other side is an excellent product); 2) "Single-sided C-board" refers to the defective product of a single-sided board; 3) "Single / double-sided A-board" refers to the excellent product of a single-sided board or a double-sided board.

These are common technical knowledge that should be mastered by those skilled in the art. Therefore, they are not described in detail in the description of the structural features of the present invention.

[0037] As a further illustration of the present invention, the operation method of the semi-automatic plywood finished product grading and stacking machine includes the grading and stacking operation of single-sided boards and the grading and stacking operation of double-sided boards;

[0038] The grading and stacking operation of double-sided boards requires grade determination for both the front and back sides of the plywood, and specifically includes the following steps:

[0039] Step 1: Turn off the single-sided B-board stacking mechanism and only retain the conveying function of the conveying swing table II therein, while the other mechanisms operate normally;

[0040] Step 2: The plywood to be repaired and graded enters the front repair and grading mechanism through the automatic board loading mechanism for repair and quality grading, and the following operations are performed according to the front grading result:

[0041] 1) If the front side is judged as a superior board, operator I presses the A key on operation panel I. At this time, the indicator lights of the A key on operation panel I and the A key on operation panel II are lit, and the single / double-sided C-board stacking mechanism is controlled to only enable the conveying function of the conveying swing table I; the plywood enters the turning mechanism through the single-sided B-board stacking mechanism and the single / double-sided C-board stacking mechanism. The turning machine of the turning mechanism turns the plywood 180°, making the back side of the plywood face up, and then enters the back repair and grading mechanism under the drive of the board output belt and the board output roller table for repair and quality grading of the back side of the plywood;

[0042] If the back side is still judged as a superior board, operator II presses the A key on operation panel II to control the double-sided B-board stacking mechanism and the double-sided C-board stacking mechanism to only enable the conveying functions of the conveying swing table III and the conveying swing table IV. The plywood enters the single / double-sided A-board stacking mechanism through the double-sided B-board stacking mechanism and the double-sided C-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the ground roller V of the board output forklift, and after being manually packed, it is transported to the superior finished product warehouse by forklift;

[0043] If the reverse side is judged as a qualified board, Operator II presses the B key on Operation Panel II, and the plywood enters the double-sided B-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the roller III of the outboard forklift. After manual packing, it is transported to the qualified finished product warehouse by forklift;

[0044] If the reverse side is judged as a defective board, Operator II presses the C key on Operation Panel II to control the double-sided B-board stacking mechanism to only enable the conveying function of the conveying swing table III. The plywood enters the double-sided C-board stacking mechanism through the double-sided B-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the roller IV of the outboard forklift and transported to the defective product treatment warehouse by forklift;

[0045] 2) If the front side is judged as a qualified board, Operator I presses the B key on Operation Panel I. At this time, the indicator lights of the B key on Operation Panel I and the B key on Operation Panel II are on. At the same time, the A key on Operation Panel II is locked, and the single / double-sided C-board stacking mechanism is controlled to only enable the conveying function of the conveying swing table I; The plywood enters the turning mechanism through the single-sided B-board stacking mechanism and the single / double-sided C-board stacking mechanism. The turning machine of the turning mechanism turns the plywood by 180°, making the reverse side of the plywood face up, and then enters the reverse side repair and grading mechanism under the drive of the outboard belt and the outboard roller table to repair and grade the reverse side of the plywood;

[0046] If the reverse side is judged as a superior board or a qualified board, Operator II presses the B key on Operation Panel II, and the plywood enters the double-sided B-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the roller III of the outboard forklift. After manual packing, it is transported to the qualified finished product warehouse by forklift;

[0047] If the reverse side is judged as a defective board, Operator II presses the C key on Operation Panel II to control the double-sided B-board stacking mechanism to only enable the conveying function of the conveying swing table III. The plywood enters the double-sided C-board stacking mechanism through the double-sided B-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the roller IV of the outboard forklift and transported to the defective product treatment warehouse by forklift;

[0048] 3) If the front side is judged as a defective board, Operator I presses the C key on Operation Panel I, and the plywood enters the single / double-sided C-board stacking mechanism through the single-sided B-board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the roller I of the outboard forklift and transported to the defective product treatment warehouse by forklift;

[0049] The grading and stacking operation of the single-sided board only judges the grade of the front side of the plywood, and the reverse side does not require grade judgment. It specifically includes the following steps:

[0050] Step 1, close the double-sided B-board stacking mechanism, and only retain the conveying function of the conveying swing table III, and the rest of the mechanisms work normally;

[0051] Step 2, the plywood to be repaired and graded enters the front repair and grading mechanism through the automatic board loading mechanism for repair and quality grading, and the following operations are performed according to the front grading results:

[0052] 1) If it is judged as a superior board, the operator I presses the A key on the operation panel I, and the plywood will enter the single / double-sided A board stacking mechanism through the single-sided B board stacking mechanism, single / double-sided C board stacking mechanism, turning mechanism, reverse repair and grading mechanism, double-sided B board stacking mechanism, and double-sided C board stacking mechanism for stacking and packing into the warehouse;

[0053] 2) If it is judged as a qualified board, the operator I presses the B key on the operation panel I, and the plywood will be stacked in the single-sided B board stacking mechanism and then packed and transported to the finished product warehouse;

[0054] 3) If it is judged as a defective board, the operator I presses the C key on the operation panel I, and the plywood will be stacked in the single / double-sided C board stacking mechanism and then transported for processing;

[0055] Among them, in operation 1), if major defects are found in the plywood at the reverse repair and grading mechanism, the operator II presses the C key on the operation panel II to stack and transport the plywood in the double-sided C board stacking mechanism.

[0056] In the above grading and stacking operation of double-sided boards, the forklift forks the plywood to be repaired and graded onto the in-feed forklift roller of the automatic board loading mechanism. The in-feed forklift roller is started to send the plywood into the lifting platform III. The automatic board suction cup sucks up the plywood and sends it along the suction cup track to the repair roller table I of the front repair and grading mechanism. The operator I (two people) jointly quickly repairs the defects (if any) on the front of the board and conducts quality grade evaluation. So far, according to the judged grade, the board has three possible destinations: for those judged as A boards, they need to be turned over for grade determination of the other side (reverse side) (it may be downgraded to B or C board); for those judged as B boards, they also need to be turned over for grade determination of the other side (reverse side) (it may be downgraded to C board); for those judged as C boards, there is no need to turn them over for grading, because no matter what the condition of the other side (reverse side) is, it can only be designated as a C board and will be directly stacked in the single / double-sided C board stacker and then transported for processing.

[0057] In the stacking operation, after pressing the control key on the operation panel (except the A key), the lifting and swinging cylinder of the corresponding stacking mechanism can be controlled to start working, raising the front end of the corresponding conveying swing table. At this time, under the backward transmission of the conveying swing table of the previous mechanism, the plywood enters the corresponding lifting platform for stacking and centering. And for each plywood stacked, the lifting platform will descend one grid. When the plywood is stacked to the set height, the whole stack of plywood is pushed into the out-feed forklift roller on the side and then transported by the forklift.

[0058] In the present invention, a set of operators are respectively provided at the front repair grading mechanism and the back repair grading mechanism to repair the plywood (if any), and after grading the front and back sides of the plywood, press the corresponding operation keys.

[0059] As a further illustration of the present invention, the semi-automatic plywood finished product grading and stacking machine is integrally arranged in a U shape.

[0060] Advantages of the present invention:

[0061] 1. When applied in actual production, the present invention enables the plywood finished product grading and packing process to realize mechanization and semi-automation in the whole process from loading the board, sorting, turning the board, grading and stacking to packing, greatly improving the production efficiency.

[0062] 2. When applied in actual production, the present invention greatly reduces the labor intensity of workers.

[0063] 3. The semi-automatic plywood grading and stacking machine of the present invention has a simple and compact structure, occupies a small area, is easy to operate and maintain, and is economical and practical. Description of the Drawings

[0088] Step 1, turn off the single-sided B board stacking mechanism, and only retain the conveying function of the conveying swing table II 9 among them, and the other mechanisms work normally (referring to the normal connection of the conveying functions between the mechanisms).

[0089] Step 2, the plywood to be repaired and graded enters the front repair and grading mechanism through the automatic board loading mechanism for repair and quality grading, and the following operations are performed according to the front grading result:

[0090] 1) If the front side is judged as a superior board, the operator I 18 presses the A key on the operation panel I 17. At this time, the indicator lights of the A key on the operation panel I 17 and the A key on the operation panel II 20 are on, and the single / double-sided C board stacking mechanism is controlled to only enable the conveying function of the conveying swing table I 6. The plywood enters the turning mechanism through the single-sided B board stacking mechanism and the single / double-sided C board stacking mechanism. The turning machine 15 of the turning mechanism turns the plywood 180°, making the reverse side of the plywood face up, and then enters the reverse repair and grading mechanism under the drive of the board output belt 16 and the board output roller table 28 for repair and quality grading of the reverse side of the plywood.

[0091] If the reverse side is still judged as a superior board, Operator II 19 presses the A key on the operation panel II 20 to control the double-sided B board stacking mechanism and the double-sided C board stacking mechanism to only enable the conveying function of the conveying swing table III 22 and the conveying swing table IV 25. The plywood enters the single / double-sided A board stacking mechanism through the double-sided B board stacking mechanism and the double-sided C board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the outfeed forklift ground roller V 32, manually packed, and then transported to the superior finished product warehouse by forklift;

[0092] If the reverse side is judged as a qualified board, Operator II 19 presses the B key on the operation panel II 20. The plywood enters the double-sided B board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the outfeed forklift ground roller III 30, manually packed, and then transported to the qualified finished product warehouse by forklift;

[0093] If the reverse side is judged as a defective board, Operator II 19 presses the C key on the operation panel II 20 to control the double-sided B board stacking mechanism to only enable the conveying function of the conveying swing table III 22. The plywood enters the double-sided C board stacking mechanism through the double-sided B board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the outfeed forklift ground roller IV 31 and transported to the defective product processing warehouse by forklift;

[0094] 2) If the front side is judged as a qualified board, Operator I 18 presses the B key on the operation panel I 17. At this time, the indicator lights of the B key on the operation panel I 17 and the B key on the operation panel II 20 are on, and at the same time, the A key on the operation panel II 20 is locked, and the single / double-sided C board stacking mechanism is controlled to only enable the conveying function of the conveying swing table I 6; The plywood enters the turning mechanism through the single-sided B board stacking mechanism and the single / double-sided C board stacking mechanism. The turning machine 15 of the turning mechanism turns the plywood 180°, making the reverse side of the plywood face up, and then enters the reverse side repair and grading mechanism under the drive of the outfeed belt 16 and the outfeed roller table 28 to repair and grade the reverse side of the plywood;

[0095] If the reverse side is judged as a superior board or a qualified board, Operator II 19 presses the B key on the operation panel II 20. The plywood enters the double-sided B board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the outfeed forklift ground roller III 30, manually packed, and then transported to the qualified finished product warehouse by forklift;

[0096] If the reverse side is judged as a defective board, Operator II 19 presses the C key on the operation panel II 20 to control the double-sided B board stacking mechanism to only enable the conveying function of the conveying swing table III 22. The plywood enters the double-sided C board stacking mechanism through the double-sided B board stacking mechanism for stacking. When the plywood is stacked to the set height, it is sent to the outfeed forklift ground roller IV 31 and transported to the defective product processing warehouse by forklift;

[0097] 3) If the front side of the plywood is judged as a defective board, the operator I 18 presses the C key on the operation panel I 17. The plywood enters the single / double-sided C board stacking mechanism through the single-sided B board stacking mechanism for stacking. After the plywood is stacked to the set height, it is sent to the outboard roller I 1 of the forklift for discharging and then transported to the defective product treatment warehouse by the forklift;

[0098] The grading and stacking operation of the single-sided board only judges the grade of the front side of the plywood, and the reverse side does not require grade judgment. The specific steps are as follows:

[0099] Step 1: Close the double-sided B board stacking mechanism and only retain the conveying function of the conveying table III 22. The other mechanisms work normally (referring to the normal connection of the conveying functions between the mechanisms);

[0100] Step 2: The plywood to be repaired and graded enters the front repair and grading mechanism through the automatic board loading mechanism for repair and quality grading, and the following operations are carried out according to the front grading result:

[0101] 1) If it is judged as a superior board, the operator I 18 presses the A key on the operation panel I 17.

At this time, under the backward conveying action of the repair roller table I 11 of the front repair and grading mechanism, the plywood enters the lifting table II 8 below the conveying table II 9 and is stacked on the lifting table II 8. And every time a piece of plywood is stacked, the lifting table II 8 will drop one grid. After the plywood is stacked to the set height, the whole stack of plywood is pushed into the outboard roller II 2 of the side forklift and then transported by the forklift.)

[0103] 3) If it is judged as a defective board, the operator I 18 presses the C key on the operation panel I 17. The plywood will be stacked in the single / double-sided C board stacking mechanism and then transported for treatment; (The specific stacking operation here is (for reference Figure 2After the operator I 18 presses the C key on the operation panel I 17, the lifting and swinging cylinder I 7 of the single / double-sided C board stacking mechanism starts to work, raising the front end of the conveying swing table I 6. At this time, under the backward conveying action of the conveying swing table II 9 of the single-sided B board stacking mechanism, the plywood enters the lifting table I 5 below the conveying swing table I 6 and is stacked on the lifting table I 5. And for each piece of plywood stacked, the lifting table I 5 will descend one grid. When the plywood is stacked to the set height, the whole stack of plywood is pushed into the side plate-out forklift roller I 1 and then transported by a forklift. (The working principle of the stacking operation of other stacking mechanisms is the same).

[0104] Among them, in operation 1), if major defects are found in the plywood at the reverse repair judgment mechanism, etc., the operator II 19 presses the C key on the operation panel II 20 to stack and transfer the plywood in the double-sided C board stacking mechanism.
