Description

Technical Field

[0001] This invention belongs to the field of automated jewelry processing, and in particular relates to an automatic jewelry bagging device. Background Technology

[0002] In the jewelry manufacturing industry, each piece of jewelry generally requires individual packaging bags, which are usually done manually. Due to the large demand for individual jewelry packaging, especially during peak seasons, jewelry bagging requires a large amount of manpower. In the jewelry manufacturing and processing industry, market demand is clearly seasonal. During peak seasons, factories often arrange a large number of packaging workers to perform packaging work. After the peak season ends, many packaging workers in factories become idle due to a lack of orders, thus causing a lot of unnecessary labor waste for jewelry manufacturing companies. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an automatic bagging device and method that can reduce manual operation and improve the efficiency of jewelry bagging.

[0004] This application provides an automatic bagging device for jewelry, including a product picking and placing mechanism, a bag opening mechanism, and a bag sealing mechanism;

[0005] The product handling mechanism includes a storage ramp, a rotating bag dropping device, and a rotating cylinder. One end of the storage ramp can be connected to one end of the rotating bag dropping device and tilted towards the rotating bag dropping device. The rotating bag dropping device is pivotally connected to the rotating cylinder and can rotate to a vertical state under the drive of the rotating cylinder. Its setting height is lower than that of the storage ramp.

[0006] The storage ramp includes a downward-sloping bottom groove, two positioning bars, and a blocking clip. The two positioning bars are parallel and spaced apart. All positioning bars are set on the bottom surface of the bottom groove and extend along the length of the bottom groove. The gaps between the positioning bars are used to store jewelry. Jewelry stored in the gaps can slide down towards the blocking clip under the action of gravity. The blocking clip is set at the lower end of the positioning bars and is used to block and release the jewelry stored between the positioning bars. After being released, the jewelry continues to slide towards the rotating drop bag device.

[0007] The rotating bag dropping device includes a rotating bottom groove pivotally connected to a rotating cylinder and a horn-shaped stopper. The horn-shaped stopper is located on the bottom surface of the rotating bottom groove and near one end of the storage ramp. It can open and close its horn opening under the control of the controller.

[0008] The bag opening mechanism includes an empty bag box, a suction bag mechanism, an empty bag transport track, an empty bag displacement device, and a bag opening vacuum nozzle. The empty bag box is located on one side of the empty bag transport track and is used to load empty packaging bags. The suction bag mechanism is used to suck up empty bags (i.e., empty packaging bags) from the empty bag box and place them onto the empty bag transport track. The empty bag transport track is used to fix and transport the empty bags to a preset position for the next step. The empty bag displacement device and the bag opening vacuum nozzle are located on one side of the empty bag transport track. The empty bag displacement device is used to remove and fix the packaging bag from the empty bag transport track, and the bag opening vacuum nozzle opens the bag opening of the packaging bag fixed on the empty bag displacement device through vacuum suction, so that the product loading and unloading mechanism can put the jewelry into the packaging bag. The empty bag box and the empty bag displacement device are respectively located at opposite ends of the empty bag transport track.

[0009] The bag sealing mechanism includes a synchronous conveyor belt, a bag sealing device, a limit bar, and a bag pushing cylinder; the bag sealing device is located directly above the middle of the synchronous conveyor belt and is used to perform the bag sealing operation; the limit bar and the bag pushing cylinder are located at the tail end of the synchronous conveyor belt and are used to push the packaging bag away from the synchronous conveyor belt.

[0010] The process involves using an empty bag displacement device to transport the packaging bags containing the jewelry to a synchronous conveyor belt.

[0011] Furthermore, the product handling mechanism has two working states: a product receiving state and a rotating bag-dropping state. In the product receiving state, one or more pieces of jewelry are placed on the storage ramp. Under the action of gravity, the jewelry slides down into the rotating bag-dropping device, which is connected to the storage ramp at this time. In the rotating bag-dropping state, a packaging bag with an upward opening is set directly below the rotating bag-dropping device. The rotating bag-dropping device rotates under the action of a rotating cylinder, changing from an inclined rotation to a vertical rotation. Under the action of gravity, the jewelry slides down into the upward-opening packaging bag, completing the bagging operation.

[0012] Furthermore, the positioning strip can be attached to the bottom groove using a magnetic attachment method.

[0013] Furthermore, the empty bag displacement device is equipped with a sponge or rubber base to support the packaging bag.

[0014] Furthermore, the empty bag box includes an empty bag groove and torsion spring pressure rollers disposed on both sides of the empty bag groove and extending towards the center of the empty bag groove.

[0015] Furthermore, the bag-opening mechanism also includes a spray nozzle located in the middle of the empty bag transport track, used for spraying codes onto the packaging bags.

[0016] Furthermore, the spray nozzle has an adjustable support frame.

[0017] The improvements of this application bring the following advantages: The automatic jewelry bagging equipment provided in the embodiments of this application adopts fully automated operation for jewelry bagging and packaging, which greatly reduces manual operation, improves work efficiency, and reduces production costs.

Detailed Implementation

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] like Figure 1-4 As shown, an automatic jewelry bagging device includes a product handling mechanism, a bag opening mechanism, and a bag sealing mechanism.

[0025] The product loading and unloading mechanism includes a storage ramp 11, a rotating bag dropping device 12, and a rotating cylinder 13. One end of the storage ramp 11 can be connected to one end of the rotating bag dropping device 12 and is inclined to the rotating bag dropping device 12. The rotating bag dropping device 12 is pivotally connected to the rotating cylinder 13 and can rotate under the drive of the rotating cylinder 13. Its setting height is lower than that of the storage ramp 11.

[0026] The product handling mechanism has two working states: product handling and rotating bagging. In the product handling state, the storage ramp 11 holds one or more pieces of jewelry. Under gravity, the jewelry slides down into the rotating bagging device 12, which is connected to the storage ramp 11. In the rotating bagging state, an upward-opening packaging bag 5 is positioned directly below the rotating bagging device 12. The rotating bagging device 12 rotates under the action of the rotating cylinder 13, changing from an inclined rotation to a vertical rotation. Under gravity, the jewelry slides down into the upward-opening packaging bag 5, completing the bagging operation.

[0027] The storage ramp 11 includes a downwardly sloping bottom groove 111, at least two positioning bars 112, and a release catch 113. The two positioning bars 112 are parallel and spaced apart, all positioned on the bottom surface of the bottom groove 111 and extending along its length. The gaps between the positioning bars 112 are used to store jewelry, which can slide towards the release catch 113 under the influence of gravity. The release catch 113 is located at the lower end of the positioning bars 112 and is used to block and release the jewelry stored between the positioning bars 112. The released jewelry continues to slide towards the rotating drop bag device 12.

[0028] The positioning strip 112 can be attached to the bottom groove 111 by magnetic attraction, so that the spacing width of the positioning strip 112 can be flexibly adjusted to accommodate the placement of different products.

[0029] The spacing between the positioning bars 112 is set to allow for the placement of multiple products, enabling operators to place many products at once, with a greater emphasis on smaller products. This saves employees a lot of time, eliminating the need for constant "preparation of material supply."

[0030] The setting of the blocking and release card 113 can release products in the temporary storage area one by one, so that the products can pass through the gate in sequence.

[0031] The rotating bag dropping device 12 includes a rotating bottom groove 121111 pivotally connected to the rotating cylinder 13 and a horn stopper 122 in the shape of an inverted V. The horn stopper 122 is located on the bottom surface of the rotating bottom groove 121111 and close to one end of the storage ramp 11. It can open and close its horn opening under the control of the controller 4.

[0032] The bagging process of the rotating bag drop device 12 includes: after the jewelry slides down from the storage ramp 11 to the rotating bag drop device 12, it is first blocked from continuing to slide down by the not yet fully opened flared mouth. Then, the rotating bag drop device 12 rotates until it is vertical under the action of the rotating cylinder 13. Then, the flared mouth of the flared stopper 122 opens, allowing the jewelry located on it to fall into the packaging bag 5 with the bag opening below the rotating bag drop device 12 through the opened flared mouth.

[0033] The rotating bag-dropping device 12 effectively ensures a smooth transition of the product during the "feeding" process and allows it to fall smoothly into the bag through the flared opening. This effectively protects the product's appearance, preventing deformation and damage.

[0034] When the rotating bag-dropping device 12 is in the product-receiving state, it engages with the storage ramp 11 at the same tilt angle. After a single product slides into the rotating bottom trough 121111, it is stopped by the horn-shaped stopper 122. When it is time to "put into the bag", the rotating bottom trough 121111 rotates to a vertical position, and then the horn-shaped stopper 122 opens, so that the product falls into the bag "short distance", providing effective protection for the product during movement.

[0035] To prevent injury from the product's falling acceleration, a sponge (or rubber) base 123 is installed at the bottom of the packaging bag 5, forming a "soft landing" when the product hits the bottom.

[0036] The bag opening mechanism includes an empty bag box 21, a suction mechanism 22, an empty bag transport track 23, a spray nozzle 24, an empty bag displacement device 25, and a bag opening vacuum nozzle 26. The empty bag box 21 is located on one side of the empty bag transport track 23 and is used to load empty packaging bags 5. The suction mechanism 22 is used to suck empty bags from the empty bag box 21 and place them onto the empty bag transport track 23. The empty bag transport track 23 is used to fix and transport the empty bags to a preset position for the next step. The spray nozzle 24 is located near the empty bag transport track 23 and is used to spray code the empty bags. The empty bag displacement device 25 and the bag opening vacuum nozzle 26 are located on one side of the empty bag transport track 23. The empty bag displacement device 25 is used to remove and fix the packaging bag 5 from the empty bag transport track 23, and the bag opening vacuum nozzle 26 opens the bag opening of the packaging bag 5 fixed on the empty bag displacement device 25 through vacuum suction, so that the product loading and unloading mechanism can put the jewelry into the packaging bag 5. Among them, the empty bag box 21, the spray dock 24 and the empty bag displacement device 25 are arranged sequentially along the direction of the empty bag transport track 23.

[0037] The process of the bag-removing and opening mechanism to pick up a bag and open the bag mouth includes: stacking multiple empty bags in the empty bag box 21, the bag suction mechanism 22 suctioning an empty bag from the empty bag box 21 and moving it to the empty bag transport track 23 and fixing it; the empty bag transport track 23 slides forward with the empty bag, transporting the empty bag to the vicinity of the inkjet terminal 24, where the inkjet terminal 24 performs inkjet coding on the empty bag; after the inkjet coding is completed, the empty bag transport track 23 continues to slide forward with the empty bag until the empty bag displacement device 25; the empty bag displacement device 25 removes the empty bag from the empty bag transport track 23 and fixes it, and then the bag opening vacuum nozzle 26 opens the bag mouth from both sides of the empty bag mouth using a vacuum suction method.

[0038] Empty bag supply is centralized using empty bag box 21, which saves manpower and reduces the time personnel spend on bag supply.

[0039] The empty bag box 21 includes an empty bag slot 211 and torsion spring pressure rollers 212 disposed on both sides of the empty bag slot 211 and extending towards the center of the empty bag slot 211. The empty bag box 21 allows personnel to easily and quickly place a stack of (opened) packaging bags 5 into the box and hold them down with the torsion spring pressure rollers 212. The middle position facilitates the suction cup of the bag suction mechanism 22 to extract the bags. After the suction cup rotates to extract each bag, the torsion spring pressure rollers 212 will automatically press down until the entire stack of packaging bags 5 has been removed.

[0040] The coding position can be positioned using a servo module, and the movement speed is uniform, making the coding accurate and the characters clear.

[0041] The bracket of the inkjet printer 24 is height-adjustable, which can adapt to the designated position of inkjet printing for different bag numbers.

[0042] The bag sealing mechanism includes a synchronous conveyor belt 31, a bag sealing device 32, a limit bar 33, and a bag pushing cylinder 34. The bag sealing device 32 is located directly above the synchronous conveyor belt 31, and the limit bar 33 and the bag pushing cylinder 34 are located at the tail end of the synchronous conveyor belt 31.

[0043] The sealing process of the sealing mechanism includes: the empty bag displacement device 25 places the product bag loaded with the product on one end of the synchronous conveyor belt 31 (let this end be the head end), the synchronous conveyor belt 31 drives the product bag forward to the vicinity of the sealing device 32, the sealing device 32 seals the bag opening; after sealing, the synchronous conveyor belt 31 drives the product bag to continue moving forward to the limit bar 33, the limit bar 33 restricts the movement and stops the movement, at the same time triggering the sensor to start the bag pushing cylinder 34, the bag pushing cylinder 34 pushes the sealed product bag away from the synchronous conveyor belt 31 to one side, completing the sealing operation.

[0044] The sealing device 32 uses a pair of clamping sealing wheels to seal the bag. The "sealing" of the product bag is achieved by synchronous wheel conveyor belt shifting. When the product bag enters the clamping sealing wheels, the "packaging bag 5 moves forward synchronously up and down and is dynamically sealed".

[0045] The synchronous conveyor belt 31 has a limit bar 33 at its end. When the product bag reaches this position, it stops moving forward. After the sensor detects this, the bag-pushing cylinder 34 behind it is activated, which pushes the product bag into the lower inclined chute 35. This corner-turning repositioning saves space.

[0046] The synchronous conveyor belt 31 is highly precise, and both the "bag sealing roller" and the conveyor belt are controlled by precision motors, ensuring a perfectly smooth bag sealing action.

[0047] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
