Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a folding conveyor. Background Art

[0002] A mobile conveyor is a conveyor line that can be moved at will. It can be used to take out items placed deep and move them to a specific location in an irregular route. In addition, it can also be moved to a production line to assist the production line, take out the material tray on the production line for unloading, or place the materials on the material tray regularly, and the mobile conveyor will deliver the material tray to the production line. When the mobile conveyor is working, the conveyor line needs to extend under the products placed deep or extend into the production line. Therefore, the conveyor line needs to reach a certain length and needs to extend outside the conveyor, resulting in the conveyor taking up a large space when idle. Summary of the invention

[0003] The object of the present invention is to provide a folding conveyor to solve the defects described in the background art.

[0004] The folding conveyor comprises a cabinet, on which a moving wheel, a main conveying line, a support rod, a collecting box and a self-locking device are installed. The moving wheel is located at the bottom of the cabinet, a rotating shaft is installed at one end of the main conveying line, the rotating shaft is connected to a folding frame through a bearing, the folding frame is installed with a folding conveying line, the bottom end shaft of the support rod is connected to a nitrogen spring, the telescopic end of the nitrogen spring is connected to the bottom wall shaft of the folding frame, so that the nitrogen spring can support the folding frame, at this time, one end of the folding conveying line is spliced ​​with the main conveying line to convey the material tray and its materials to the main conveying line, and the collecting box is located at the other end of the main conveying line so that the main conveying line can convey the material tray and its materials to the main conveying line. The materials are sent into the collection box, and the self-locking device is located on the side wall of the cabinet, so that when the folding frame is folded down to be close to the cabinet, the self-locking device is used to fix the folding frame; the main conveyor line is provided with a bridge track that is inclined downward to the top of the collection box, and a hook is provided on the bottom wall of the material tray. A bracket, a wire take-up drum and a motor are installed below the main conveyor line, and a hook is carried on the bracket, so that when the main conveyor line transports the material tray to the bridge track, the hook is buckled into the hook and pulls the hook, and the wire take-up drum is wound with a traction rope connected to the hook, and the motor drives the wire take-up drum to wind up the traction rope to pull the material tray that has completed loading and unloading on the bridge track back to the main conveyor line and send it back.

[0005] According to the technical solution, the present invention can achieve the following beneficial effects:

[0006] 1. Since the folding frame bearing is connected to one end of the main conveying line, and the folding frame is supported by the nitrogen spring, so that the folding frame is folded down to one side of the cabinet, when the folding conveyor is idle, the folding conveying line extending out of the cabinet can be folded into the cabinet, thereby reducing the occupied space;

[0007] 2. When transporting products, after the folding conveyor line transports the products to the main conveyor line, the folding conveyor line extending outside the cabinet can be folded into the cabinet, so as to facilitate the cabinet to move in a narrow passage. When the product is transported to the target location, the folding conveyor line opens outward and connects with the main conveyor line. The main conveyor line transports the product to the folding conveyor line, and the folding conveyor line transports the product to the unloading location.

[0008] 3. When assisting the production line, the folding conveyor line is connected to the production line so that the folding conveyor line can transport the products on the production line to the main conveyor line, and the main conveyor line then transports the products to the collection box for collection;

[0009] 4. When assisting the production line, the folding conveyor line can also be connected to the production line so that the folding conveyor line can transport the material tray on the production line to the main conveyor line, and the main conveyor line transports the material tray to the collection box, so that the operator or mechanical structure can unload the product in the material tray into the collection box, or the operator or mechanical structure can load the product in the collection box into the material tray. After that, the main conveyor line transports the material tray to the production line for recycling through the folding conveyor line;

[0010] 5. Furthermore, after the collection box is filled with products or the products in the collection box are emptied, the folding conveyor line is connected to the production line to reduce the space occupied by the folding conveyor, thereby facilitating the collection box to move to the target position for unloading or replenishing materials.

[0011] 6. The main conveyor line is set up with a bridge track that slopes downward to the top of the collection box, so that the main conveyor line can transport the products into the collection box;

[0012] 7. When the main conveyor line transports the material tray to the bridge track, the hook is buckled into the hook and pulled. At this time, the traction rope connected to the hook will pull the material tray and limit it on the bridge track, and the material tray will tilt toward the collection box. At this time, the technicians in this field only need to adjust the inclination angle of the bridge track to automatically pour the products in the material tray into the collection box, or facilitate the operator or mechanical mechanism to unload the products in the material tray into the collection box, or facilitate the operator or mechanical mechanism to load the products in the collection box into the material tray;

[0013] 8. After the material tray on the bridge track is loaded or unloaded, the motor drives the take-up drum to reel in the traction rope, and the traction rope pulls the material tray on the bridge track back to the main conveyor line. The main conveyor line then sends the material tray back to the production line through the folding conveyor line, thus realizing the automatic retrieval of the material tray;

[0014] 9. When the main conveyor line sends the material tray to the folding conveyor line, the bracket will limit the movement of the hook, and the hook will automatically detach from the hook.

[0015] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0016] In some embodiments, a cabinet is installed with a support plate, and a buffer cylinder, a wire-wound resistor and an information collection system are installed on the support plate. A compressible and deformable airbag is placed in the buffer cylinder, and the airbag supports a support column connected to the bottom wall of the collection box. The support column slides in the buffer cylinder, and a conductive finger for contacting and energizing the wire-wound resistor is installed on the support column. The wire-wound resistor is arranged in parallel with the buffer cylinder, so that when the collection box presses down the support column, the support column drives the conductive finger to slide on the winding of the wire-wound resistor. The information collection system is connected with the wire-wound resistor and the conductive finger by electrical signals, and the information collection system is used to convert the resistance value into the weight of the collection box;

[0017] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0018] 1. By arranging a compressible and deformable air bag in the buffer cylinder to support the support column, the product can be shock-absorbed and buffered when it falls into the collection box, thereby reducing damage to the product;

[0019] 2. When the product falls into the collection box, on the basis of shock absorption and buffering, the weight of the product presses down the support column, and the support column drives the conductive finger to slide on the winding wire of the wound resistor. The information collection system can obtain the weight of the collection box according to the change of resistance value and detect the weight of the collection box in real time;

[0020] 3. Since the weight of the collection box can be detected in real time, the folding conveyor line can automatically determine whether to continue to transport the products on the production line to the main conveyor line based on the material quantity in the collection box.

[0021] In some embodiments, the support plate is installed with a slide rail, and the conductive finger is installed with a slider that cooperates with the slide rail;

[0022] According to the technical solution, when the supporting column drives the conductive finger to move, the conductive finger can slide on the winding wire of the wound resistor more stably.

[0023] In some embodiments, a limit bar is provided at the end of the bridge track for preventing the material tray from sliding into the collection box;

[0024] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0025] 1. When the main conveyor line transports the material tray to the bridge track, the limit bar can prevent the material tray from sliding into the collection box;

[0026] 2. When the material tray is bridging the track, the limit bar can support the material tray, thereby reducing the force on the traction rope;

[0027] 3. When the material tray is tilted downward to pour the product in the material tray into the collection box, the limit bar can serve as a fulcrum for the material tray to be tilted downward.

[0028] In some embodiments, a lifting cylinder is installed under the bridge track, and the lifting cylinder drives a lifting block for lifting one side of the material tray to above the collection box;

[0029] According to the technical solution, when the main conveyor line transports the material tray to the bridge track, the lifting cylinder drives the lifting block to lift one side of the material tray to above the collection box, thereby automatically pouring the products in the material tray into the collection box.

[0030] In some embodiments, a guide plate extending from the bracket to the bridge track is installed below the main conveyor line, so that when the take-up drum reels the traction rope, the hook returns to the bracket along the guide plate;

[0031] According to the technical solution, when the hook and the hook buckle are accidentally separated during the process of the main conveyor line conveying the material tray to the folding conveyor line, the hook buckle returns to the bracket along the guide plate.

[0032] In some embodiments, the bracket is provided with a concave arc-shaped magnet portion, and the lower corner of the hook is provided with an arc-shaped portion. When the traction rope pulls the hook through the arc-shaped magnet portion, the arc-shaped magnet portion absorbs the arc-shaped portion, so that the traction rope pulls the hook to stand up on the bracket;

[0033] According to the technical solution, when the traction rope pulls the hook back to the bracket, the arc-shaped portion will pass through the arc-shaped magnet portion, and the arc-shaped magnet portion absorbs the arc-shaped portion. At this time, the hook uses the arc-shaped portion as a fulcrum and is pulled upright on the bracket by the pulling force of the traction rope, thereby facilitating the separation of the hook on the material tray and the hook on the next material tray into the hook.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

[0045] like Figures 1 to 7As shown, this specific embodiment provides a folding conveyor, which includes a cabinet 1, the cabinet 1 is equipped with a moving wheel 11, a main conveying line 2, a support rod 3, a collection box 4 and a self-locking device 31, the moving wheel 11 is located at the bottom of the cabinet 1, one end of the main conveying line 2 is equipped with a rotating shaft 32, the rotating shaft 32 is connected to a folding frame 33 through a bearing, the folding frame 33 is equipped with a folding conveying line 34, the bottom end shaft of the support rod 3 is connected to a nitrogen spring 35, the telescopic end of the nitrogen spring 35 is connected to the bottom of the folding frame 33 The wall axis is connected so that the nitrogen spring 35 can support the folding frame 33. At this time, one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2 to convey the material, or the material tray 6 and its material to the main conveyor line 2. The collection box 4 is located at the other end of the main conveyor line 2, so that the main conveyor line 2 can convey the material or material tray 6 above it into the collection box 4. The self-locking device 31 is located on the side wall of the cabinet 1. When the folding frame 33 is folded down to fit the cabinet 1, the self-locking device 31 is used to fix the folding frame 33. The self-locking device 31 can be selected as a buckle, a latch or a screw to fix the folded folding frame 33 on one side of the cabinet 1.

[0046] Since the bearing of the folding frame 33 is connected to one end of the main conveyor line 2 and the folding frame 33 is supported by the nitrogen spring 35, the folding frame 33 is folded downward to one side of the cabinet 1. Therefore, when the folding conveyor is idle, the folding conveyor line 34 extending out of the cabinet 1 can be folded into the cabinet 1, thereby reducing the occupied space.

[0047] When transporting products, after the folding conveyor line 34 transports the products to the main conveyor line 2, the folding conveyor line 34 extending out of the cabinet 1 can be folded into the cabinet 1, thereby facilitating the movement of the cabinet 1 in a narrow passage. When the product is transported to the target position, the folding conveyor line 34 opens outward and connects with the main conveyor line 2. The main conveyor line 2 transports the products to the folding conveyor line 34, and the folding conveyor line 34 transports the products to the unloading position.

[0048] When assisting the production line, the folding conveyor line 34 is connected to the production line so that the folding conveyor line 34 can transport the products on the production line to the main conveyor line 2, and the main conveyor line 2 then transports the products to the collection box 4 for collection. When assisting the production line, the folding conveyor line 34 can also be connected to the production line so that the folding conveyor line 34 can transport the material tray 6 on the production line to the main conveyor line 2, so that the folding conveyor line 34 can transport the material tray 6 on the production line to the main conveyor line 2, and the main conveyor line 2 transports the material tray 6 to the collection box 4, so that the operator or mechanical structure can unload the product in the material tray 6 into the collection box 4, or so that the operator or mechanical structure can load the product in the collection box 4 into the material tray 6, and then the main conveyor line 2 transports the material tray 6 to the production line for recycling through the folding conveyor line 34. After the collecting box 4 is filled with products or the products in the collecting box 4 are emptied, it is connected to the production line through the folding conveyor line 34 to reduce the space occupied by the folding conveyor, thereby facilitating the collection box 4 to move to the target position for unloading or replenishing materials.

[0049] In some embodiments, a support plate 41 is installed on the cabinet 1, and a buffer cylinder 42, a wire-wound resistor 43 and an information collection system are installed on the support plate 41. A compressible and deformable airbag 44 is placed in the buffer cylinder 42. The airbag 44 supports a support column 45 connected to the bottom wall of the collection box 4. The support column 45 slides in the buffer cylinder 42. The support column 45 is installed with a conductive finger 46 for contacting the wire-wound resistor 43 to energize. The wire-wound resistor 43 is arranged parallel to the buffer cylinder 42, so that when the collection box 4 presses down the support column 45, the support column 45 drives the conductive finger 46 to slide on the winding of the wire-wound resistor 43. The information collection system is connected to the wire-wound resistor 43 and the conductive finger 46 by electrical signals. The information collection system is used to convert the resistance value into the weight of the collection box 4. The information collection system can be a conventional computer.

[0050] By arranging a compressible and deformable air bag 44 in the buffer cylinder 42 to support the support column 45, the product can be shock-absorbed and buffered at the moment the product falls into the collection box 4, thereby reducing damage to the product.

[0051] When the product falls into the collection box 4, on the basis of shock absorption and buffering of the product, the support column 45 is pressed down by the weight of the product, and the support column 45 compresses the air in the airbag 44. At the same time, the support column 45 drives the conductive finger 46 to slide on the winding wire of the wound resistor 43, so that the information collection system can obtain the weight of the collection box 4 according to the change of resistance value and detect the weight of the collection box 4 in real time; since the weight of the collection box 4 can be detected in real time, the folding conveyor line 34 can automatically determine whether to continue to transport the products on the production line to the main conveyor line 2 according to the material quantity of the collection box 4.

[0052] Since the airbag 44 may be deflated or otherwise experience reduced supporting force, before placing the product in the collection box 4, the information collection system may use the resistance value at this time as the initialization resistance value, thereby correcting the pressure on the support column 45 corresponding to the resistance value.

[0053] In some embodiments, the support plate 41 is installed with a slide rail 47, and the conductive finger 46 is installed with a slider 48 that cooperates with the slide rail 47; so that when the support column 45 drives the conductive finger 46 to move, the conductive finger 46 can slide more stably on the winding wire of the wound resistor 43.

[0054] In some embodiments, the main conveyor line 2 is provided with a bridge track 5 that is inclined downward to above the collection box 4 , so that the main conveyor line 2 can transport the products into the collection box 4 .

[0055] In some embodiments, a hook 61 is provided on the bottom wall of the material tray 6, and a bracket 71, a wire take-up drum 72 and a motor 73 are installed below the main conveyor line 2. A hook 74 is supported on the bracket 71, and the bracket 71 is provided with a vertical surface for the hook 74 to lean against, and the vertical surface is provided with an electromagnet for adsorbing the side of the hook 74. When the hook 61 pulls the hook 74 to move, the electromagnet stops adsorbing the hook 74, so that when the main conveyor line 2 transports the material tray 6 to the bridge track 5, the hook 61 is buckled into the hook 74 and pulls the hook 74, and the wire take-up drum 72 is wound with a traction rope 75 connected to the hook 74, and the motor 73 drives the wire take-up drum 72 to reel in the traction rope 75 to pull the material tray 6 that has completed loading and unloading on the bridge track 5 back to the main conveyor line 2 and send it back.

[0056] When the main conveyor line 2 transports the material tray 6 to the bridge track 5, the hook 61 is buckled into the hook 74 and pulls the hook 74. At this time, the traction rope 75 connected to the hook 61 will pull and hang the material tray 6 and limit it on the bridge track 5, and the material tray 6 will tilt toward the collection box 4. At this time, the technicians in this field only need to adjust the inclination angle of the bridge track 5 to automatically pour the products in the material tray 6 into the collection box 4, or facilitate the operator or mechanical mechanism to unload the products in the material tray 6 into the collection box 4, or facilitate the operator or mechanical mechanism to load the products in the collection box 4 into the material tray 6.

[0057] After the material tray 6 on the bridge track 5 completes loading or unloading, the motor 73 drives the take-up drum 72 to reel in the traction rope 75, and the traction rope 75 pulls the material tray 6 on the bridge track 5 back to the main conveyor line 2, and the hook 74 is pulled back to the bracket 71 by the traction rope 75. At this time, the electromagnet of the bracket 71 will adsorb and fix the hook 74, and the main conveyor line 2 will send the material tray 6 back to the production line through the folding conveyor line 34. At the same time, the hook 61 is separated from the hook 74, thereby realizing the automatic retrieval of the material tray 6.

[0058] When the main conveyor line 2 delivers the material tray 6 to the folding conveyor line 34 , the bracket 71 will restrict the movement of the hook 74 , and at this time, the hook 61 will automatically disengage from the hook 74 .

[0059] In some embodiments, a limiting bar 51 is provided at the end of the bridging track 5 for preventing the material tray 6 from sliding into the collecting box 4 .

[0060] When the main conveyor line 2 transports the material tray 6 to the bridge track 5, the limit bar 51 can prevent the material tray 6 from sliding into the collection box 4; and when the material tray 6 is on the bridge track 5, the limit bar 51 can support the material tray 6, thereby reducing the force on the traction rope 75. When the material tray 6 is tilted down to pour the product in it into the collection box 4, the limit bar 51 can serve as a fulcrum for the material tray 6 to flip down.

[0061] In some embodiments, a lifting cylinder 52 is installed under the bridging track 5 , and the lifting cylinder 52 drives a lifting block 53 for lifting one side of the material tray 6 to above the collecting box 4 .

[0062] When the main conveyor line 2 transports the material tray 6 to the bridge track 5 , the lifting cylinder 52 drives the lifting block 53 to lift one side of the material tray 6 and flip it down to the top of the collection box 4 , thereby automatically pouring the products in the material tray 6 into the collection box 4 .

[0063] In some embodiments, a guide plate 76 extending from the bracket 71 to the bridging track 5 is installed below the main conveyor line 2 so that when the take-up drum 72 reels the traction rope 75 , the hook 74 returns to the bracket 71 along the guide plate 76 .

[0064] When the main conveyor line 2 is conveying the material tray 6 to the folding conveyor line 34 , if the hook 61 and the hook buckle 74 are accidentally separated, the hook buckle 74 returns to the bracket 71 along the guide plate 76 .

[0065] In some embodiments, the bracket 71 is provided with a concave arc-shaped magnet portion 711, and the lower corner of the hook 74 is provided with an arc-shaped portion 741. When the traction rope 75 pulls the hook 74 to pass through the arc-shaped magnet portion 711, the arc-shaped magnet portion 711 absorbs the arc-shaped portion 741, so that the traction rope 75 pulls the hook 74 to stand up on the bracket 71.

[0066] When the traction rope 75 pulls the hook 74 back to the bracket 71, the arc portion 741 will pass through the arc-shaped magnet portion 711, and the arc-shaped magnet portion 711 will absorb the arc-shaped portion 741. At this time, the hook 74 uses the arc-shaped portion 741 as a fulcrum, and the pulling force of the traction rope 75 pulls the hook 74 to stand up on the bracket 71, thereby facilitating the separation of the hook 74 on the material tray 6 and facilitating the hook 61 on the next material tray 6 to be buckled into the hook 74.

[0067] In order to further illustrate the folding conveyor described in this specific embodiment, the following examples are now listed. Example 1

[0068] This embodiment provides a folding conveyor, which includes a cabinet 1 and a collection box 4. A moving wheel 11 is installed at the bottom of the cabinet 1. The cabinet 1 is equipped with a main conveying line 2, a support rod 3, a self-locking device 31 and a support plate 41.

[0069] A rotating shaft 32 is installed at one end of the main conveyor line 2, and the rotating shaft 32 is connected to a folding frame 33 through a bearing. The folding frame 33 is installed with a folding conveyor line 34, and the bottom end shaft of the support rod 3 is connected to a nitrogen spring 35. The telescopic end of the nitrogen spring 35 is connected to the bottom wall shaft of the folding frame 33, so that the nitrogen spring 35 can support the folding frame 33. At this time, one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2 to convey the material to the main conveyor line 2; the self-locking device 31 is located on the side wall of the cabinet 1, so that when the folding frame 33 is folded down to be attached to the cabinet 1, the self-locking device 31 is used to fix the folding frame 33; the collecting box 4 is located at the other end of the main conveyor line 2, and the main conveyor line 2 is tilted downward to the bridge track 5 above the collecting box 4, so that the main conveyor line 2 can deliver the material above it into the collecting box 4.

[0070] The support plate 41 is installed with a buffer cylinder 42, a wound resistor 43 and an information collection system. A compressible and deformable airbag 44 is placed in the buffer cylinder 42. The airbag 44 supports a support column 45 connected to the bottom wall of the collection box 4. The support column 45 slides in the buffer cylinder 42. The support column 45 is installed with a conductive finger 46 for contacting the wound resistor 43 to energize. The wound resistor 43 is arranged parallel to the buffer cylinder 42, so that when the collection box 4 presses down the support column 45, the support column 45 drives the conductive finger 46 to slide on the winding of the wound resistor 43. The information collection system is connected with the wound resistor 43 and the conductive finger 46 by electrical signals. The information collection system is used to convert the resistance value into the weight of the collection box 4; the support plate 41 is installed with a slide rail 47, and the conductive finger 46 is installed with a slider 48 that cooperates with the slide rail 47.

[0071] The following is the instructions for use of the folding conveyor described in this embodiment:

[0072] 1. When the folding conveyor is idle, the folding conveyor line 34 extending outside the cabinet 1 is folded into the cabinet 1, thereby reducing the occupied space.

[0073] 2. When transporting products, the nitrogen spring 35 can support the folding frame 33, and the folding conveyor line 34 extends outside the cabinet 1 and one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2. By pushing the cabinet 1 to move, the extended part of the folding conveyor line 34 is extended under the product placed deep or spliced ​​with the production line. The folding conveyor line 34 transports the product to the main conveyor line 2, and the main conveyor line 2 sends the product into the collection box 4. Thereafter, the folding conveyor line 34 extending outside the cabinet 1 is folded into the cabinet 1. At this time, the cabinet 1 can move on the narrow passage. After the product is transported to the target position, the folding conveyor line 34 opens outward and splices with the main conveyor line 2. The main conveyor line 2 transports the product to the folding conveyor line 34, and the folding conveyor line 34 transports the product to the unloading position.

[0074] 3. When the product falls into the collection box 4, a compressible and deformable air bag 44 is arranged in the buffer tube 42 to support the support column 45, so as to perform shock absorption and buffering at the moment the product falls into the collection box 4; at the same time, when the product falls into the collection box 4, the support column 45 is pressed down by the weight of the product, and the support column 45 drives the conductive finger 46 to slide on the winding wire of the wound resistor 43, so that the information collection system can obtain the weight of the collection box 4 according to the change of the resistance value and detect the weight of the collection box 4 in real time; in addition, when the folding conveyor line 34 is spliced ​​with the production line to collect products, the weight of the collection box 4 can be detected in real time to determine whether the collection box 4 is fully loaded. Example 2

[0075] This embodiment provides a folding conveyor, which includes a material tray 6, a cabinet 1 and a collection box 4, and a moving wheel 11 is installed at the bottom of the cabinet 1. A hook 61 is provided on the bottom wall of the material tray 6. The cabinet 1 is installed with a main conveying line 2, a support rod 3, a self-locking device 31 and a support plate 41.

[0076] A rotating shaft 32 is installed at one end of the main conveyor line 2, and a folding frame 33 is connected to the rotating shaft 32 through a bearing. A folding conveyor line 34 is installed on the folding frame 33. A nitrogen spring 35 is connected to the bottom end of the support rod 3. The telescopic end of the nitrogen spring 35 is connected to the bottom wall of the folding frame 33, so that the nitrogen spring 35 can support the folding frame 33. At this time, one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2 to convey the material tray 6 to the main conveyor line 2.

[0077] The collection box 4 is located at the other end of the main conveyor line 2. The main conveyor line 2 is tilted downward to the bridge track 5 above the collection box 4, so that the main conveyor line 2 can deliver the material tray 6 above it into the collection box 4. The end of the bridge track 5 is provided with a limit bar 51 for preventing the material tray 6 from sliding into the collection box 4. A lifting cylinder 52 is installed below the bridge track 5, and the lifting cylinder 52 drives a lifting block 53 for lifting one side of the material tray 6 and flipping it down to the top of the material tray 6.

[0078] The support plate 41 is equipped with a buffer cylinder 42, a wire-wound resistor 43 and an information collection system. A compressible and deformable airbag 44 is placed in the buffer cylinder 42. The airbag 44 supports a support column 45 connected to the bottom wall of the collection box 4. The support column 45 slides in the buffer cylinder 42. The support column 45 is equipped with a conductive finger 46 for contacting and energizing the wire-wound resistor 43. The wire-wound resistor 43 is arranged parallel to the buffer cylinder 42, so that when the collection box 4 presses down the support column 45, the support column 45 drives the conductive finger 46 to slide on the winding of the wire-wound resistor 43. The information collection system is connected with the wire-wound resistor 43 and the conductive finger 46 by electrical signals. The information collection system is used to convert the resistance value to the weight of the collection box 4. The support plate 41 is equipped with a slide rail 47, and the conductive finger 46 is equipped with a slider 48 that cooperates with the slide rail 47.

[0079] A bracket 71, a take-up drum 72 and a motor 73 are installed below the main conveyor line 2. A hook 74 is carried on the bracket 71, so that when the main conveyor line 2 conveys the material tray 6 to the bridge track 5, the hook 61 is buckled into the hook 74 and pulls the hook 74, and the take-up drum 72 is wound with a traction rope 75 connected to the hook 74. The motor 73 drives the take-up drum 72 to wind up the traction rope 75, so as to pull the material tray 6 on the bridge track 5 that has completed loading and unloading back to the main conveyor line 2. A guide plate 76 extending from the bracket 71 to the bridge track 5 is installed below the main conveyor line 2, so that when the take-up drum 72 winds up the traction rope 75, the hook 74 returns to the bracket 71 along the guide plate 76. The bracket 71 is provided with a concave arc-shaped magnet portion 711, and the lower corner of the hook 74 is provided with an arc-shaped portion 741. When the traction rope 75 pulls the hook 74 to pass through the arc-shaped magnet portion 711, the arc-shaped magnet portion 711 absorbs the arc-shaped portion 741, so that the traction rope 75 pulls the hook 74 to stand up on the bracket 71.

[0080] The following is the instructions for use of the folding conveyor described in this embodiment:

[0081] 1. When the folding conveyor is idle, the folding conveyor line 34 extending outside the cabinet 1 is folded into the cabinet 1, thereby reducing the occupied space.

[0082] 2. When the folding conveyor is used to feed the material tray 6 on the production line, the nitrogen spring 35 can support the folding frame 33, and the folding conveyor line 34 extends outside the cabinet 1 and one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2. By pushing the cabinet 1 to move, the extended part of the folding conveyor line 34 is extended into and spliced ​​with the production line; thereafter, the production line transports the material tray 6 to the folding conveyor line 34, the folding conveyor line 34 transports the material tray 6 to the main conveyor line 2, and the main conveyor line 2 transports the material tray 6 to the bridge track 5. At this time, the limit bar 51 of the bridge track 5 supports the material tray 6; in the process of the main conveyor line 2 transporting the material tray 6 to the bridge track 5, the hook 61 is buckled into the hook 74 and the hook 74 is pulled, and the traction rope 75 connected to the hook 61 will pull and hang the material tray 6 and limit it on the bridge track 5; thereafter, the operator or the machine This mechanism can place the products in the collection box 4 on the material tray 6; thereafter, the motor 73 drives the take-up drum 72 to reel in the traction rope 75, and the traction rope 75 pulls the hook 74 back to the bracket 71, and the hook 74 pulls the material tray 6 on the bridge track 5 back to the main conveyor line 2, and the main conveyor line 2 sends the material tray 6 back to the production line through the folding conveyor line 34; in the process of the traction rope 75 pulling the hook 74 back to the bracket 71, the arc portion 741 will pass through the arc magnet portion 711, and the arc magnet portion 711 absorbs the arc portion 741. At this time, the hook 74 uses the arc portion 741 as a fulcrum, and the pulling force of the traction rope 75 pulls the hook 74 to stand up on the bracket 71 and rely on the bracket 71. When the main conveyor line 2 sends the material tray 6 to the folding conveyor line 34, the hook 74 on the material tray 6 is separated from the hook 74;

[0083] In addition, after the product is taken out from the collection box 4, the gravity of the collection box 4 is reduced, and the airbag 44 also props up the support column 45. The support column 45 drives the conductive finger 46 to slide on the winding wire of the wound resistor 43. The information collection system can obtain the weight of the collection box 4 according to the change of resistance value and detect the weight of the collection box 4 in real time. Therefore, the weight change of the collection box 4 can be used to determine whether the product in the collection box 4 is taken out.

[0084] 3. When the folding conveyor is used to unload the material tray 6 on the production line, the nitrogen spring 35 can support the folding frame 33, and the folding conveyor line 34 extends outside the cabinet 1 and one end of the folding conveyor line 34 is spliced ​​with the main conveyor line 2. By pushing the cabinet 1 to move, the extended part of the folding conveyor line 34 is extended into and spliced ​​with the production line; thereafter, the production line transports the material tray 6 to the folding conveyor line 34, the folding conveyor line 34 transports the material tray 6 to the main conveyor line 2, and the main conveyor line 2 transports the material tray 6 to the bridge track 5. At this time, the limit bar 51 of the bridge track 5 supports the material tray 6; in the process of the main conveyor line 2 transporting the material tray 6 to the bridge track 5, the hook 61 is buckled into the hook 74 and pulls the hook 74, and the traction rope 75 connected to the hook 61 will pull and hang the material tray 6 and limit it on the bridge track 5; thereafter, the lifting cylinder 52 drives the lifting block 53 to lift one side of the material tray 6 and flip it down to the top of the collection box 4, and the material The product in the tray 6 is poured into the collection box 4; thereafter, the lifting cylinder 52 drives the lifting block 53 to reset, and one side of the material tray 6 also falls back onto the bridge track 5; thereafter, the motor 73 drives the take-up drum 72 to reel in the traction rope 75, and the traction rope 75 pulls the hook 74 back to the bracket 71, and the hook 74 pulls the material tray 6 on the bridge track 5 back to the main conveyor line 2, and the main conveyor line 2 sends the material tray 6 back to the production line through the folding conveyor line 34; When the guide rope 75 pulls the hook 74 back to the bracket 71, the arc portion 741 passes through the arc magnet portion 711, and the arc magnet portion 711 attracts the arc portion 741. At this time, the hook 74 uses the arc portion 741 as a fulcrum, and the pulling force of the traction rope 75 pulls the hook 74 to stand up on the bracket 71 and lean on the bracket 71. When the main conveyor line 2 delivers the material tray 6 to the folding conveyor line 34, the hook 74 on the material tray 6 is separated from the hook 74;

[0085] When the product falls into the collection box 4, a compressible and deformable air bag 44 is arranged in the buffer tube 42 to support the support column 45, so as to perform shock absorption and buffering at the moment the product falls into the collection box 4; at the same time, when the product falls into the collection box 4, the support column 45 is pressed down by the weight of the product, and the support column 45 drives the conductive finger 46 to slide on the winding wire of the wound resistor 43, so that the information collection system can obtain the weight of the collection box 4 according to the change of the resistance value and detect the weight of the collection box 4 in real time; in addition, when the folding conveyor line 34 is spliced ​​with the production line to collect products, the weight of the collection box 4 can be detected in real time to determine whether the collection box 4 is full.
