Description

Technical Field

[0002] Fasteners are mechanical parts used to connect multiple components together and are widely used in industrial fields such as automobile manufacturing, construction, mechanical engineering, and electronic equipment production.

[0003] There are many types of fasteners, the most common of which include bolts, screws, nuts, rivets, etc. These fasteners are usually made of metals such as carbon steel, stainless steel, copper and aluminum alloys. After the fasteners are produced, they need to be packaged and packed, and after packaging, the packaging boxes are placed on the shelves in the warehouse.

[0004] In the process of placing packaging boxes on the shelves, a palletizer is needed. In the related technology, Chinese patent application CN115384997A discloses a multi-station aisle stacker. The multi-station aisle stacker is equipped with a plurality of temporary storage stations through the cooperation of a loading platform, a fork mechanism, a lifting mechanism, a temporary storage station, etc. The fork mechanism can pick up goods from the shelves and place them in a plurality of temporary storage stations for storage, or pick up goods from the temporary storage station and place them on the shelves, and then perform outbound or inbound operations at one time.

[0005] Although the above-mentioned multi-station aisle stacker can improve the efficiency of cargo stacking to a certain extent, it is found in actual use that in the process of the fork mechanism picking up the cargo, since the cargo suddenly switches from a static state to a moving state, the cargo may move relative to the fork mechanism under the action of inertia. While affecting the accuracy of the subsequent cargo stacking position, when the cargo is high, it may also cause asynchronous movement in the height direction of the cargo, making it easy for the cargo to fall over, posing a safety hazard.

A sleeve frame 44 is fixedly arranged on the right side wall of the vertical sliding seat 4, and the sleeve frame 44 is slidably sleeved on the vertical rail 3 during installation; the telescopic loading platform 5 is horizontally inserted into the opening of the vertical sliding seat 4 during installation.

[0026] To facilitate providing the driving force for the horizontal sliding seat 2 to slide along the lying rail 1, the fastener finished - product packaging line shuttle - type palletizing machine is further provided with a second driving motor, a third gear, and a fifth rack. The second driving motor is inserted into the inside of the horizontal sliding seat 2 during installation, and the motor shaft of the second driving motor is vertically and downwardly arranged; the third gear is fixedly sleeved on the motor shaft of the second driving motor during installation and is located outside the bottom of the horizontal sliding seat 2; the fifth rack is fixedly arranged on the lying rail 1, is arranged parallel to the lying rail 1, and meshes with the third gear.

[0027] To facilitate providing the driving force for the vertical sliding seat 4 to slide along the vertical rail 3, the fastener finished - product packaging line shuttle - type palletizing machine is further provided with a third driving motor, a reducer, a first sprocket, a second sprocket, and a chain 31. The third driving motor and the reducer are both inserted into the inside of the horizontal sliding seat 2 during installation. The motor shaft of the third driving motor is horizontally arranged and is connected to the input end of the reducer; the first sprocket is fixedly sleeved on the output end of the reducer, and the axis of the first sprocket is horizontally arranged; the second sprocket is arranged at the top of the vertical rail 3 and can rotate by itself, and the axis of the second sprocket and the axis of the first sprocket are arranged in the same vertical plane; the chain 31 is set as a "C" - shaped structure, and one end is fixedly connected to the top of the sleeve frame 44, and the other end sequentially bypasses the first sprocket, the second sprocket, then penetrates through the vertical sliding seat 4 and is fixed to the top of the vertical sliding seat 4.

[0028] To facilitate passing through the chain 31, as Figure 3 and Figure 5 shown, two mounting holes 401 are arranged at the left - hand top of the vertical sliding seat 4. The two mounting holes 401 are arranged at intervals along the length direction of the vertical sliding seat 4. The chain 31 forms a "U" - shaped structure during installation to respectively penetrate through the two mounting holes 401.

[0029] When in use, first place the goods on the top of the telescopic loading platform 5, then start the second driving motor, which synchronously drives the horizontal sliding seat 2, the vertical rail 3 and the vertical sliding seat 4 to move on the horizontal rail 1 through the engagement between the third gear and the fifth rack, so as to drive the goods to be moved to the same vertical plane as the stacking position; then start the third driving motor, which drives the first sprocket to rotate through the reducer, and the first sprocket synchronously drives the vertical sliding seat 4 to move on the vertical rail 3 through the chain 31, and the second sprocket follows, so as to drive the goods to be moved to the same horizontal plane as the stacking position; then drive the telescopic loading platform 5 to extend, the telescopic loading platform 5 synchronously drives the goods to extend, and at the same time drives the counterweight block 6 to move in the opposite direction to balance the torque generated by the goods on the telescopic loading platform 5 through the counterweight block 6, and at the same time drives the telescopic loading platform 5 to extend downward through the lifting mechanism, so that the goods have a tendency to move forward, thereby being able to offset the tendency of the goods to move backward due to inertia, thereby ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged.

[0030] When the telescopic loading platform 5 drives the goods to the stacking position, the third drive motor is started, and the third drive motor drives the first sprocket to rotate through the reducer. The first sprocket synchronously drives the vertical sliding seat 4 to slide downward along the vertical rail 3 through the chain 31 to place the goods on the shelf.

[0031] Then the telescopic loading platform 5 and the counterweight 6 are driven to reset; then the third drive motor is started, and the third drive motor drives the first sprocket to rotate through the reducer, and the first sprocket synchronously drives the vertical sliding seat 4 to slide downward along the vertical rail 3 to the initial position through the chain 31; repeat the above process, and the goods can be continuously placed on the shelf.

[0032] In some embodiments, the counterweight block 6 can slide along the extension direction of the vertical rail 3; the lifting mechanism is configured to include a protrusion 71, the protrusion 71 is provided on the vertical sliding seat 4, and is located on the sliding path of the counterweight block 6 along the extension direction perpendicular to the vertical rail 3, so that when the counterweight block 6 passes through the protrusion 71, the counterweight block 6 can be lifted by the protrusion 71 and slide along the extension direction of the vertical rail 3 to push the telescopic loading platform 5.

[0033] Specifically in this embodiment, Figure 7 As shown, a sliding groove 402 is provided through the bottom of the opening of the vertical sliding seat 4, and the sliding groove 402 extends along the length direction of the vertical sliding seat 4. The length direction of the vertical sliding seat 4 is parallel to the moving direction of the telescopic loading platform 5. The sliding groove 402 forms a sliding path for the counterweight block 6 along the extension direction perpendicular to the vertical rail 3; the counterweight block 6 is set to an "I" shape structure, and the small end is stopped at the top of the sliding groove 402, the middle part is slidably inserted in the sliding groove 402, and the large end is suspended at the bottom of the sliding groove 402. A push block 61 is fixed on the top of the counterweight block 6, as shown Figure 4As shown, the top of the push block 61 contacts the bottom of the telescopic loading platform 5 when in use; the protrusion 71 is set to a tooth-shaped structure, and the inclined surface of the protrusion 71 faces the counterweight block 6 to better guide the movement of the counterweight block 6. The protrusion 71 is fixedly set at the bottom of the opening of the vertical sliding seat 4 during installation, and is set close to the sliding groove 402 and close to the middle of the sliding groove 402.

[0034] Initially, the counterweight 6 is located in the middle of the sliding slot 402 .

[0035] During use, when the telescopic loading platform 5 is extended toward the direction close to the shelf, the counterweight block 6 simultaneously moves toward the direction away from the shelf. During the movement of the counterweight block 6, when the counterweight block 6 passes the protrusion 71, the counterweight block 6 moves upward synchronously under the push of the protrusion 71, and the counterweight block 6 pushes the telescopic loading platform 5 synchronously, so that the height of the end of the telescopic loading platform 5 close to the shelf in the vertical direction is lower than the height of the other end of the telescopic loading platform 5 away from the shelf in the vertical direction, so that the telescopic loading platform 5 extends downward in the conveying direction, and then the goods have a tendency to move toward the direction close to the shelf under the guidance of the inclined plane. At this time, under the action of inertia, the goods have a tendency to move away from the shelf, thereby achieving the offset of the movement trend and ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged.

[0036] In a further embodiment, during the process of placing goods on an existing palletizer, since the goods suddenly switch from a moving state to a stationary state, the goods may move relative to the fork mechanism under the action of inertia, thereby affecting the accuracy of the goods stacking position. To solve this problem, the shuttle pallet palletizer of the fastener finished product packaging line is configured to also include a pulling and lowering mechanism, which is configured to drive the telescopic loading platform 5 to extend upward when the telescopic loading platform 5 drives the goods to switch from a moving state to a stationary state.

[0037] During use, when the goods are switched from a moving state to a stationary state, the telescopic loading platform 5 is driven to extend upward by the pulling and lowering mechanism, so that the goods tend to move backward, thereby offsetting the tendency of the goods to move forward due to inertia, thereby ensuring the accuracy of the goods stacking position.

[0038] In a further embodiment, the pulling and lowering mechanism is configured to include a sink 81, a socket 82 and an insertion rod 83, the sink 81 is arranged on the vertical sliding seat 4, and is located at the end of the sliding path of the counterweight block 6 along the extension direction perpendicular to the vertical rail 3; the socket 82 is arranged on the counterweight block 6; the insertion rod 83 is hinged on the telescopic loading platform 5, and can form a snap fit with the socket 82, so that when the counterweight block 6 passes through the sink 81, the counterweight block 6 can synchronously pull the telescopic loading platform 5 through the snap fit between the socket 82 and the insertion rod 83.

[0039] Specifically in this embodiment, Figure 7 As shown, the sink 81 is provided at the bottom of the opening of the vertical sliding seat 4 and is connected to the sliding groove 402 to form a T-shaped structure; the insertion hole 82 is provided as a strip structure and is provided on the front and rear side walls of the small end of the counterweight 6 and extends along the width direction of the vertical sliding seat 4; Figure 5 As shown, the insertion rod 83 is configured as an L-shaped structure, with the top hinged to the bottom of the telescopic loading platform 5 and the bottom suspended and disposed toward the middle of the telescopic loading platform 5 .

[0040] During use, when the counterweight block 6 moves to the end of the sliding groove 402, the insertion rod 83 is synchronously locked into the insertion hole 82, and the counterweight block 6 moves downward synchronously under the action of gravity to be inserted into the sink groove 81; during the movement of the counterweight block 6, the counterweight block 6 synchronously drives the other end of the telescopic loading platform 5 away from the shelf direction to move downward through the insertion rod 83, so that the height of the end of the telescopic loading platform 5 close to the shelf direction in the vertical direction is higher than the height of the other end of the telescopic loading platform 5 away from the shelf direction in the vertical direction, so that the telescopic loading platform 5 extends upward along the conveying direction, and then under the guidance of the inclined plane, the goods have a tendency to move in the direction away from the shelf. At this time, under the action of inertia, the goods have a tendency to move in the direction close to the shelf, thereby achieving the offset of the movement trend and ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged.

[0041] In a further embodiment, in order to improve the applicability of the palletizer, there are two sinking grooves 81, which are respectively arranged at the two ends of the sliding path of the counterweight block 6 along the extension direction perpendicular to the vertical rail 3; there are two insertion rods 83, which are arranged at intervals along the extension direction perpendicular to the vertical rail 3.

[0042] Specifically in this embodiment, the two sinking grooves 81 are arranged so as to form an “I”-shaped structure together with the sliding groove 402 .

[0043] During use, when the telescopic loading platform 5 is extended in any direction toward or away from the shelf, with the cooperation of any set of grooves 81, insertion rods 83 and insertion holes 82, the telescopic loading platform 5 can be tilted upward. Under the guidance of the inclined surface, the goods have a tendency to move backward, so that when the goods switch from a moving state to a stationary state, the tendency of the goods to move forward due to inertia can be offset, thereby ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged and ensuring the accuracy of the stacking position of the goods.

[0044] In other embodiments, in order to improve the applicability of the palletizer, the number of the protrusions 71 is two, and they are arranged at intervals along the sliding path of the counterweight 6 perpendicular to the extension direction of the vertical rail 3 .

[0045] During use, when the counterweight block 6 slides in any direction towards or away from the shelf, with the cooperation of any protrusion 71, the telescopic loading platform 5 can be tilted downward, and the goods have a tendency to move forward under the guidance of the inclined surface, so that when the goods switch from a static state to a moving state, the tendency of the goods to move backward due to inertia can be offset, thereby ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged and the accuracy of the stacking position of the goods is guaranteed.

[0046] In other embodiments, the shuttle palletizer for the fastener finished product packaging line is configured to further include a driving mechanism, which is configured to provide a driving force for the telescopic loading platform 5 and the counterweight block 6 to slide in opposite directions.

[0047] In a further embodiment, the driving mechanism is configured to include a first gear 91, a first rack 92, a second rack 93 and a driving member, the first gear 91 is arranged on the vertical sliding seat 4 and can rotate on its own; the first rack 92 is extended along an extension direction perpendicular to the vertical rail 3 and is fixed on the counterweight block 6; the second rack 93 is arranged parallel to the first rack 92 and is fixed on the telescopic loading platform 5, the first rack 92 and the second rack 93 are respectively engaged on both sides of the first gear 91; the driving member is configured to provide a driving force for the first gear 91 to rotate on its own.

The motor shaft of the first drive motor 94 is arranged upward in the vertical direction and passes through the open bottom of the vertical sliding seat 4 to be coaxially inserted on the first gear 91.

[0049] When in use, the first drive motor 94 is started, and the first drive motor 94 drives the first gear 91 to rotate. The rotation of the first gear 91 synchronously drives the first rack 92 and the second rack 93 to move in opposite directions, thereby driving the counterweight block 6 and the telescopic loading platform 5 to move in opposite directions.

[0050] In some other embodiments, the shuttle palletizer of the finished fastener packaging line is further provided with a transmission component, which is configured to transmit the rotation of the first gear 91 to the telescopic loading platform 5 to drive the telescopic loading platform 5 to extend and retract.

[0055] like Figure 7 As shown, the third rack 102 is fixedly arranged at the bottom of the opening of the vertical sliding seat 4 during installation and is located on the left side of the sliding groove 402 , and the tooth surface of the third rack 102 is arranged upward to engage with the second gear 101 .

[0056] When in use, the first drive motor 94 is started, and the first drive motor 94 drives the first gear 91 to rotate. The rotation of the first gear 91 synchronously drives the first rack 92 and the second rack 93 to move in opposite directions, thereby driving the counterweight block 6 and the intermediate platform 51 to move in opposite directions; during the movement of the intermediate platform 51, the intermediate platform 51 synchronously drives the second gear 101 to move, and the second gear 101 rotates by engaging with the third rack 102. The rotation of the second gear 101 synchronously drives the loading platform 52 to extend through the engagement with the fourth rack 103, so as to realize the extension and retraction of the retractable loading platform 5.

[0057] In other embodiments, to improve safety during use, such as Figure 5 As shown, two anti-collision blocks 522 are arranged at the bottom of the loading platform 52, at the front and rear ends of the fourth rack 103. The anti-collision blocks 522 and the fourth rack 103 are arranged at intervals along the width direction of the loading platform 52 to achieve an anti-collision effect when in use.

[0058] In other embodiments, to simplify the control logic, such as Figure 6 As shown, two travel switches 43 are provided at the bottom of the opening of the vertical sliding seat 4, and the two travel switches 43 are arranged at intervals along the length direction of the vertical sliding seat 4; Figure 5 As shown, a trigger piece 513 is provided at the bottom of the middle sub-platform 51 . The trigger piece 513 is provided in an inverted T-shaped structure and is configured to trigger the travel switch 43 .

[0059] During use, when the counterweight 6 moves to the end of the sliding slot 402, the trigger plate 513 synchronously triggers the limit switch 43, and the limit switch 43 sends a signal to delay the start of the first drive motor 94 to reverse, thereby driving the counterweight 6 and the telescopic loading platform 5 to reset.

[0060] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: When in use, first place the goods on the top of the loading platform 52, and then start the second drive motor. The second drive motor synchronously drives the horizontal sliding seat 2, the vertical rail 3 and the vertical sliding seat 4 to move on the horizontal rail 1 through the engagement between the third gear and the fifth rack, so as to drive the goods to move to the same vertical plane as the stacking position; then start the third drive motor, the third drive motor drives the first sprocket to rotate through the reducer, and the first sprocket synchronously drives the vertical sliding seat 4 to move on the vertical rail 3 through the chain 31, and the second sprocket follows to drive the goods to move to the same horizontal plane as the stacking position.

[0061] Then start the first drive motor 94, which drives the first drive motor 94 to rotate. The rotation of the first gear 91 synchronously drives the first rack 92 and the second rack 93 to move in opposite directions, thereby driving the counterweight block 6 and the intermediate platform 51 to move in opposite directions, wherein the intermediate platform 51 moves toward the direction close to the shelf, and the counterweight block 6 moves away from the shelf; in the process of movement of the intermediate platform 51, the intermediate platform 51 synchronously drives the second gear 101 to move, and the second gear 101 rotates by engaging with the third rack 102. The rotation of the second gear 101 synchronously drives the loading platform 52 to extend through engagement with the fourth rack 103, and the loading platform 52 synchronously drives the goods to extend.

[0062] When the telescopic loading platform 5 is extended toward the direction of the shelf, the counterweight block 6 simultaneously moves toward the direction away from the shelf. During the movement of the counterweight block 6, when the counterweight block 6 passes the protrusion 71, the counterweight block 6 moves upward synchronously under the push of the protrusion 71, and the counterweight block 6 pushes the telescopic loading platform 5 synchronously, so that the height of the end of the telescopic loading platform 5 close to the shelf in the vertical direction is lower than the height of the other end of the telescopic loading platform 5 away from the shelf in the vertical direction, so that the telescopic loading platform 5 extends downward in the conveying direction, and then the goods have a tendency to move toward the direction of the shelf under the guidance of the inclined plane. At this time, under the action of inertia, the goods have a tendency to move away from the shelf, thereby achieving the offset of the movement trend and ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged.

[0063] When the counterweight 6 moves to the end of the sliding slot 402, the insertion rod 83 is synchronously inserted into the insertion hole 82, and the counterweight 6 moves downward synchronously under the action of gravity to be inserted into the sink 81; in the process of movement of the counterweight 6, the counterweight 6 synchronously drives the other end of the telescopic loading platform 5 away from the shelf direction to move downward through the insertion rod 83, so that the height of the end of the telescopic loading platform 5 close to the shelf direction in the vertical direction is higher than the height of the other end of the telescopic loading platform 5 away from the shelf direction in the vertical direction, so that the telescopic loading platform 5 extends upward along the conveying direction, and then makes the goods have a tendency to move away from the shelf under the guidance of the inclined plane. At this time, under the action of inertia, the goods have a tendency to move toward the direction close to the shelf, thereby achieving the offset of the movement trend and ensuring that the position of the goods on the telescopic loading platform 5 remains unchanged.

[0064] When the loading platform 52 drives the goods to the stacking position, the third drive motor is started, and the third drive motor drives the first sprocket to rotate through the reducer. The first sprocket synchronously drives the vertical sliding seat 4 to slide downward along the vertical rail 3 through the chain 31 to place the goods on the shelf.

[0065] When the goods are placed on the shelf, the first drive motor 94 starts to reverse, thereby driving the counterweight 6 and the telescopic loading platform 5 to reset; then the third drive motor is started, and the third drive motor drives the first sprocket to rotate through the reducer, and the first sprocket synchronously drives the vertical sliding seat 4 to slide downward along the vertical rail 3 to the initial position through the chain 31.

[0066] Repeat the above process to continuously place goods on the shelves.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
