As shown in fig. 2, the present invention also discloses a cookie producing apparatus 10, wherein the cookie producing apparatus 10 is mainly used for solving some technical problems encountered in the baking process in the above-mentioned step five.

As shown in fig. 2, the cookie making apparatus 10 of the present invention includes an oven 20 (shown in fig. 3) and a cookie loading cart 30 used in cooperation with the oven 20.

As shown in fig. 4, the cookie loading cart 30 includes: a loading vehicle body 100, two supporting conveyors 200, and a plurality of trays 300. The two supporting conveyors 200 are mounted on the loading vehicle body 100 and form a receiving space 400, and a plurality of trays 300 can be sequentially arranged in the receiving space 400 at intervals along the vertical direction.

The cookies formed by extrusion are placed on the tray 300, and then the plurality of trays 300 filled with the cookies are sequentially arranged in the accommodating space 400 at intervals along the vertical direction, so that the loading of the cookies can be completed.

The cookie loading cart 30 loaded with cookies is pushed into the oven 20, the door of the oven is closed, the baking time and the baking temperature are set, and the cookies in the oven body are baked by the oven 20.

Because a plurality of trays 300 are arranged in the accommodating space 400 at intervals in sequence along the vertical direction, how to simply, quickly and effectively finish the sequential arrangement of the plurality of trays 300 at intervals along the vertical direction is a technical problem to be solved by research and development personnel.

Specifically, as shown in fig. 5 and 6, the supporting and conveying device 200 includes: a fixed frame 210, an upper rotating shaft 220, a lower rotating shaft 230, a conveyor belt 240, and a plurality of support structures 250.

The fixing frame 210 is fixed on the loading vehicle body 100, the upper rotating shaft 220 and the lower rotating shaft 230 are rotatably arranged on the fixing frame 210, the conveyor belt 240 is arranged between the upper rotating shaft 220 and the lower rotating shaft 230 in an end-to-end surrounding manner, the conveyor belt 240 performs conveying motion along the vertical direction, and the plurality of supporting structures 250 are sequentially arranged at intervals along the conveying direction of the conveyor belt 240.

The tray 300 has a left side holder 310 (shown in fig. 5) and a right side holder, and the left side holder 310 and the right side holder of the tray 300 are respectively pressed and held on the supporting structures 250 of the two supporting conveyors 200 on the same level.

Due to the structural design, a worker can place one of the trays 300 on the topmost supporting structure 250, the conveyor belt 240 can perform conveying movement from top to bottom under the action of the gravity of the tray 300, the supporting structure 250 which is originally positioned at the topmost part can descend, and the adjacent supporting structure 250 can be refilled at the topmost part; the worker may then place another tray 300 on the topmost support structure 250, which tray 300 continues to descend in the direction of travel of the conveyor belt 240; by repeating the above steps, the trays 300 can be sequentially arranged at intervals in the vertical direction.

The above-structured support conveyor 200 also suffers from such a problem during use. When one of the trays 300 is placed on the topmost support structure 250, the conveyor belt 240 is moved from top to bottom by the gravity of the tray 300, and the support structure 250, which was originally at the topmost position, is lowered, and during this process, if the conveyor belt 240 is not temporarily locked, the conveyor belt 240 is continuously conveyed, so that the topmost tray 300 is directly dropped to the bottommost position, which makes no sense. For this reason, how to temporarily lock the conveyor belt 240 to prevent the tray 300 from directly falling down is a technical problem to be solved, so that the tray 300 falls down in a stepwise manner (only a small distance is required for each action).

As shown in fig. 7, the support structure 250 includes: supporting base plate 251, movable locking piece 252.

The supporting base 251 is fixed to the conveyor belt 240, and the movable locking member 252 is rotatably provided on the supporting base 251 by a torsion spring (not shown).

As shown in fig. 7, the movable lock 252 has an upper lock catch end 253 and an unlocking hold end 254. The top of the fixing frame 210 is provided with an anti-falling clamping groove 211 (as shown in fig. 5), and the anti-falling clamping groove 211 is matched with the upper locking clamping end 253. The left and

right holders

310 and 254 of the tray 300 are pressed against the unlocking pressing end 254 to disengage the upper locking catch end 253 from the anti-falling catch groove 211.

Because the top of the fixing frame 210 is provided with the anti-falling clamping groove 211, and the upper locking clamping end 253 of the movable locking piece 252 of the topmost supporting structure 250 is clamped in the anti-falling clamping groove 211, the whole conveyor belt 240 is temporarily fixed under the condition that the upper locking clamping end 253 and the anti-falling clamping groove 211 are clamped with each other;

when one of the trays 300 is placed on the topmost supporting structure 250, the left carrying handle 310 and the right carrying handle of the tray 300 are pressed on the unlocking pressing end 254, the movable locking piece 252 rotates, the upper locking clamping end 253 is separated from the anti-falling clamping groove 211, the conveying belt 240 continues to perform conveying movement, and the supporting structure 250 which is originally positioned at the topmost part descends along with the conveying belt 240;

along with the conveying movement of the conveyor belt 240, a new supporting structure 250 will reach the topmost position again, and under the action of the torsion spring, the upper locking clamping end 253 of the movable locking piece 252 of the new supporting structure 250 will be clamped in the anti-falling clamping groove 211, so that the whole conveyor belt 240 is limited again and cannot fall down again, and thus the conveyor belt 240 can be temporarily fixed to prevent the tray 300 from falling down directly;

the worker places another tray 300 on the topmost supporting structure 250, the upper locking clamping end 253 is separated from the anti-falling clamping groove 211 again, and at the moment, the conveying belt 240 continues to perform conveying movement again;

the staff constantly places new trays 300 in the topmost supporting structure 250, and this is repeated, so that the arrangement of the plurality of trays 300 in sequence at intervals along the vertical direction can be simply, quickly and effectively realized, and thus, the staff can put the trays 300 without bending down, and the labor intensity is reduced.

Further, as shown in fig. 7, the supporting structure 250 further includes a tray full space limit board 255, the tray full space limit board 255 is located above the supporting bottom plate 251, and a holder accommodating cavity 256 is formed between the tray full space limit board 255 and the supporting bottom plate 251. It can be seen that the left side holder 310 and the right side holder of the tray 300 are received in the holder receiving chamber 256.

As shown in fig. 8, when one of the trays 300 reaches the bottom of the fixing frame 210, the bottom of the tray 300 is pressed against the loading vehicle body 100, and at this time, the left side holder 310 and the right side holder of the tray 300 are separated from the supporting bottom plate 251 and pressed against the tray full position limit indicator 255, and the entire conveyor belt 240 stops conveying (the conveyor belt 240 is locked) by the limit action of the tray full position limit indicator 255, and at this time, it can be verified that the entire supporting and conveying device 200 is full of the tray 300. In addition, it should be noted that, when one of the trays 300 reaches the bottom of the fixing frame 210, even if the left and right carrying handles 310 and 254 of the topmost tray 300 are pressed against the unlocking pressing end 254, the locking and clamping end 253 is disengaged from the anti-falling clamping groove 211, and the topmost tray 300 does not fall down because the whole conveyor belt 240 is locked, which can maximally ensure that the supporting and conveying device 200 can fully load the tray 300 without the topmost tray being unable to be placed.

It is emphasized that the cookie loading cart 30 of the above-described construction may also be used with automated manufacturing equipment. For example, the machine extrudes dough to be placed in the tray 300, the tray 300 is driven by the assembly line to perform conveying movement, the cookie loading cart 30 is placed at the tail end of the assembly line, and when the tray 300 reaches the tail end of the assembly line, the tray 300 is pushed out of the assembly line by the air cylinder and enters the topmost end of the fixing frame 210, so that a plurality of trays 300 can be arranged at intervals in sequence along the vertical direction.

As shown in fig. 9, the oven 20 is provided with a turntable 21 inside, and the turntable 21 is provided with a latch mechanism 40.

The bottom of the loading vehicle body 100 is provided with a clamping block 110 (as shown in fig. 2 and 9) matched with the clamping mechanism 40, and the bottom of the loading vehicle body 100 is also provided with a moving roller 120 (as shown in fig. 4).

The cookie loading cart 30 is pushed into the inside of the case of the toaster 20, and during the toasting process, the turntable 21 will drive the cookie loading cart 30 thereon to rotate, so that the cookies on the tray 300 can be heated uniformly. By providing the click mechanism 40 and the click block 110 to be engaged with each other, the cookie loading cart 30 can be stably fixed to the turntable 21.

The lifting plate 610 is disposed inside the fixing box 500 in a lifting and sliding manner, the clamping head 620 is fixed on the lifting plate 610 and penetrates through the top surface of the fixing box 500, and the first lifting and resetting elastic member 630 is used for providing a resetting elastic force for the lifting plate 610 so that the clamping head 620 resets from the top surface of the fixing box 500 to the inside. In this embodiment, the first lifting return elastic element 630 is a cylindrical spring, one end of the cylindrical spring is fixed inside the box body of the fixed box, and the other end of the cylindrical spring is pressed on the plate surface of the lifting plate 610; the number of the cylindrical springs is four, and the four cylindrical springs are respectively located at four corners of the lifting plate 610.

As shown in fig. 11, the active triggering member 700 includes an active rotating shaft 710 and a triggering cam 720 disposed on the active rotating shaft 710. The driving shaft 710 is rotatably disposed inside the fixing box 500 by a first elastic member (not shown) for restoring the driving shaft 710 so that the trigger cam 720 lifts the lifting plate 610 and the engaging head 620 protrudes from the inside of the fixing box 500 to the top surface. In this embodiment, the first torsion return elastic member is a torsion spring structure.

As shown in fig. 11, the reset trigger 800 includes a trigger shaft 810 and a trigger lever 820 disposed on the trigger shaft 810. The trigger shaft 810 is rotatably disposed inside the fixed box 500 by a second torsion return elastic member (not shown) for providing a return elastic force to the trigger shaft 810 so that the trigger lever 820 protrudes from the inside of the fixed box 500 to the top surface. In this embodiment, the second torsional return elastic member is a torsion spring structure.

As shown in fig. 11, the intermediate connector 900 includes an intermediate shaft 910 and a linkage block 920 disposed on the intermediate shaft 910.

the working personnel hook the pedal lever 901 by using the tiptoes, the pedal lever 901 drives the driving rotating shaft 710 to rotate, the driving rotating shaft 710 further drives the trigger cam 720 on the driving rotating shaft to rotate, the thicker wheel surface of the trigger cam 720 is not abutted against the lifting plate 610, the lifting plate 610 resets under the elastic acting force of the first lifting reset elastic piece 630, the clamping joint 620 on the lifting plate 610 falls into the box body from the top surface of the fixed box 500, the clamping joint 620 is not clamped with the clamping groove 111 any more, and the whole cookie loading cart 30 can be pushed out of the box body;

it should be noted that before the cookie loading cart 30 is pushed out of the box, the foot tip is required to be kept to hook the foot lever 901, if the foot tip is separated from the foot lever 901, the active rotating shaft 710 will reset again under the action of the first torsion reset elastic member, and the thicker wheel surface of the trigger cam 720 on the active rotating shaft 710 will again support the lifting plate 610, so that the clamping joint 620 is clamped in the clamping groove 111 again, and the unlocking purpose cannot be achieved;

the pedal lever 901 is hooked up by the toes, the pedal lever 901 drives the driving rotating shaft 710 to rotate, the driving rotating shaft 710 further drives the trigger cam 720 thereon to rotate, when the trigger cam 720 rotates by an angle, the linkage block 920 has a movable space, because the third torsional return elastic member is used for providing a return elastic force for the intermediate rotating shaft 910 so that the linkage block 920 has a tendency of being pressed towards the trigger cam 720, the intermediate rotating shaft 910 and the linkage block 920 can rotate, thus, the clamping end 921 on the linkage block 920 can be separated from the clamping groove 821 on the trigger lever 820, and the trigger lever 820 is no longer limited by the linkage block 920;

after the clamping block 110 is separated from the clamping mechanism 40, the whole reset trigger 800 is in a complete free state, under the action of the second torsional reset elastic piece, the trigger rotating shaft 810 rotates, the trigger rotating shaft 810 further drives one end of the trigger rod 820 to protrude from the inside of the fixed box 500 to the top surface, and thus, the next clamping block 110 and the clamping mechanism 40 are quickly clamped again to be ready for preparation;

it should be particularly noted that when the foot tip of the worker no longer applies a force to the pedal lever 901 after the clamping block 110 is separated from the clamping mechanism 40, the first torsion return elastic member still applies a return elastic force to the active rotating shaft 710, however, at this time, the active rotating shaft 710 is already limited and cannot rotate, because the clamping end 921 of the linkage block 920 is already separated from the clamping groove 821 of the trigger lever 820 and the trigger lever 820 also rotates, the clamping end 921 presses on the outer edge of the trigger lever 820, and the trigger lever 820 indirectly clamps the trigger cam 720 through the linkage block 920, so that the active rotating shaft 710 cannot be smoothly returned; although the torsion of the first torsion return elastic member is much greater than that of the second torsion return elastic member in design, the active shaft 710 has no way to return due to the above-mentioned locking structure;

when the worker pushes the cookie loading cart 30 into the box body of the oven 20 again, during the moving process of the clamping block 110, the clamping block 110 touches the trigger lever 820 protruding from the top surface of the fixing box 500, the trigger lever 820 is forced to drive the trigger spindle 810 to rotate, and the trigger lever 820 is accommodated in the fixing box 500 again;

when the trigger lever 820 rotates by an angle in cooperation with the trigger shaft 810, the retaining groove 821 on the trigger lever 820 corresponds to the retaining end 921 of the linkage block 920 again, so that the linkage block 920 has a tendency to rotate;

when the linkage block 920 has a tendency to rotate, because the torsion of the first torsion return elastic member is very large, the first torsion return elastic member drives the trigger cam 720 to rotate in the opposite direction through the driving rotating shaft 710, on one hand, the trigger cam 720 causes the linkage block 920 to rotate, so that the clamping end 921 of the linkage block 920 reenters the clamping groove 821 of the trigger rod 820, on the other hand, because the clamping end 921 of the linkage block 920 reenters the clamping groove 821 of the trigger rod 820, a small angle formed by the rotation of the linkage block 920 provides a moving space for the rotation of the trigger cam 720, the trigger cam 720 abuts against the lifting plate 610 to lift (the first lifting return elastic member 630 is compressed), the clamping head 620 of the lifting plate 610 protrudes out of the top surface of the fixing box 500 again and is clamped in the clamping groove 111 of the clamping block 110, and the clamping block 110 is clamped.

The clamping mechanism 40 of the invention has the following technical effects:

on one hand, the stability of the clamping between the clamping block 110 and the clamping mechanism 40 is ensured; before the cookie loading cart 30 is pushed out of the box body, the action that the tiptoes hook the pedal levers 901 is required to be kept, if the tiptoes are separated from the pedal levers 901, the driving rotating shafts 710 are reset under the action of the first torsion reset elastic pieces, the thicker wheel surfaces of the trigger cams 720 on the driving rotating shafts 710 push the lifting plate 610 again, so that the clamping joints 620 are clamped in the clamping grooves 111 again, and the unlocking purpose cannot be achieved; after the cookie loading cart 30 is pushed out of the box body, the tiptoes are separated from the pedal levers 901, and the trigger cam 720 is locked and temporarily cannot lift the lifting plate 610 under the cooperation of the reset trigger 800 and the intermediate connecting member 900, so that the clamping head 620 cannot protrude out of the top surface of the fixed box 500;

on the other hand, the clamping block 110 is ensured to be clamped with the clamping mechanism 40 quickly; since the trigger lever 820 is already protruded from the top surface of the fixed box 500, as long as the latch block 110 touches the trigger lever 820, the components will have chain reaction, and finally the latch head 620 is protruded from the top surface of the fixed box 500 again.

It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
