Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a cross-type dual-channel conveyor line alternating release device. Background Technology

[0002] In the production of optical lenses, packaging is required after they leave the factory to prevent scratches on their surface. Packaging machines are typically used. The machine first places the lenses into blister packs, then places the blister packs containing the lenses into boxes, and finally packs multiple boxes into a carton. The carton is then sealed with adhesive tape, completing the packaging. The sealed carton is then conveyed to the storage area via a conveyor line. To improve packaging efficiency, multiple packaging machines are usually used. Cartons from these machines are conveyed via branch conveyor lines to the main conveyor line, and then to the storage area. There are instances where branch conveyor lines intersect with the main conveyor line (e.g., a cross conveyor line disclosed in application number 202122714081.X). Existing cross-type dual-channel conveyor lines, such as... Figure 1 As shown, the cross-type dual-channel conveyor line includes a main conveyor line 100 and a branch conveyor line 200. The branch conveyor line 200 is perpendicular to the main conveyor line 100, and its end connects to the middle section of the main conveyor line 100. The upstream section of the main conveyor line 100 and the branch conveyor line 200 form two inflow channels, and the downstream section of the main conveyor line 100 forms an outflow channel. When packaging boxes on the branch conveyor line enter the main conveyor line, they are prone to collisions with packaging boxes on the main conveyor line, resulting in congestion and blockages. Workers need to manually clear the blockages in a timely manner. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a cross-type dual-channel conveyor alternating release device to solve the technical problem that packaging boxes on cross-type dual-channel conveyors are prone to congestion and blockage when they meet at the intersection in the prior art.

[0004] To achieve the above technical objectives, the present invention provides a cross-type dual-channel conveyor line alternating release device, comprising:

[0005] The blocking mechanism includes two stops and two first elastic members. The two stops correspond one-to-one with two inflow channels, and the two first elastic members are connected one-to-one with the two stops so that both stops are in a blocking state. The packaging box on the inflow channel can push the corresponding stop to move so that the stop is in a release state.

[0006] A locking mechanism is connected to both of the stops. When a package on one of the inflow channels pushes the corresponding stop, the locking mechanism is triggered to lock the other stop.

[0007] Furthermore, the stop corresponding to the main conveyor line is located upstream of the stop corresponding to the branch conveyor line.

[0008] Furthermore, the cross-type dual-channel conveyor alternating release device also includes a bracket, which is disposed on the side of the junction of the main conveyor line and the branch conveyor line and located in the upstream section of the main conveyor line. One end of each of the two stops is rotatably connected to the bracket and can reciprocate in the horizontal plane around its rotation axis. During the reciprocating rotation of the two stops around its rotation axis, it can switch between blocking and releasing states. One end of each of the two first elastic members is connected to the bracket, and the other end of each of the two first elastic members is connected to the two stops one by one.

[0009] Furthermore, the locking mechanism includes two locking components. One end of each locking component slides against one of the two stops. As the packaging box on the inflow channel pushes the corresponding stop to rotate downstream around its rotation axis, the stop can push the locking component that slides against it to move, so that the other end of the locking component engages with the other stop, thereby locking the other stop.

[0010] Furthermore, both of the aforementioned stops include a rotating shaft, a stop bar, a chuck, and a semi-ring. The rotating shaft is vertically arranged, and both its upper and lower ends are rotatably connected to the bracket. The stop bar is horizontally arranged, and one end of the stop bar is fixedly connected to the rotating shaft. The stop bar is used to block or allow packaging boxes flowing into the channel. The chuck and the semi-ring are respectively arranged on both sides of the stop bar and are coaxially fixedly sleeved on the rotating shaft. One end of the first elastic member is connected to the bracket, and the other end of the first elastic member is connected to the chuck, so that the stop bar is in a blocking state. When both of the aforementioned stops are in a blocking state, one end of each of the two locking components slides against the ends of the two semi-rings. During the rotation of one of the rotating shafts, the corresponding semi-ring can push the locking component that slides against it to move, so that the other end of the locking component engages with the other chuck.

[0011] Furthermore, when the baffle is in the blocking state, the baffle is perpendicular to the conveying direction of the inflow channel.

[0012] Furthermore, the two stops are staggered so that the two chucks correspond to the two semi-rings in an alternating manner, and the two locking components are staggered and located between the corresponding chucks and semi-rings respectively.

[0013] Furthermore, both ends of the two semi-rings are sloping structures.

[0014] Furthermore, the chuck has a groove on its arc-shaped wall. Both locking components include a pin, a locking rod, and a second elastic element. The pin is vertically arranged, and one end of the pin is fixedly connected to the bracket. The locking rod is horizontally arranged and corresponds to the chuck and the half-ring. The middle part of the locking rod is rotatably sleeved on the other end of the pin. One end of the second elastic element is connected to the bracket, and the other end of the second elastic element is connected to the locking rod, so that one end of the locking rod slides against the half-ring. When both stops are in the blocking state, one end of the two locking rods slides against the ends of the two half-rings one by one. During the rotation of one of the rotating shafts, the corresponding half-ring can push the locking rod that slides against it to rotate around the pin, so that the other end of the locking rod abuts into the groove on the other chuck.

[0015] Furthermore, the cross-type dual-channel conveyor alternating release device also includes a guiding mechanism. The guiding mechanism is located on the side of the junction of the main conveyor line and the branch conveyor line, and is located in the downstream section of the main conveyor line. It is used to slide against the packaging boxes on the branch conveyor line so that the packaging boxes on the branch conveyor line enter the main conveyor line.

[0016] Compared with the prior art, the beneficial effects of this utility model include: In use, when a package on one of the inflow channels reaches the corresponding stop, it will push the corresponding stop to move, thereby putting the stop in a release state. The package passes the stop and enters the outflow channel. After the package passes the stop, the stop is reset under the action of the corresponding first elastic member and is in a blocking state again. Since the locking mechanism is triggered when the package on the inflow channel pushes the corresponding stop, the other stop can be locked. At this time, when the package in the other inflow channel reaches the corresponding stop, it cannot push the corresponding stop to move, and the package on the inflow channel cannot smoothly pass the stop and enter the outflow channel. This alternating release device can effectively prevent the package on the branch conveyor line from colliding with the package on the main conveyor line when it enters the main conveyor line, thereby avoiding congestion and blockage of the package at the intersection.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This utility model provides a cross-type dual-channel conveyor line alternating release device, the structure of which is as follows: Figure 2 - Figure 4 As shown, the device includes a blocking mechanism 300 and a locking mechanism 400. The blocking mechanism 300 includes two stops 310 and two first elastic members 320. The two stops 310 correspond one-to-one with two inflow channels, and the two first elastic members 320 are connected one-to-one with the two stops 310, so that both stops 310 are in a blocking state. The packaging box on the inflow channel can push the corresponding stop 310 to move, so that the stop 310 is in a releasing state. The locking mechanism 400 is connected to both stops 310. When the packaging box on one of the inflow channels pushes the corresponding stop 310 to move, the locking mechanism 400 is triggered, so that the other stop 310 is in a locked state.

[0024] In use, when a package on one of the inflow channels reaches the corresponding stop 310, it pushes the stop 310 to move, thus putting the stop 310 in a release state. The package passes the stop 310 and enters the outflow channel. After the package passes the stop 310, the stop 310 is reset by the action of the first elastic member 320 and is in a blocking state again. Since the locking mechanism 400 is triggered when the package on the inflow channel pushes the stop 310, the other stop 310 can be locked. At this time, when the package in the other inflow channel reaches the stop 310, it cannot push the stop 310 to move, and the package on the inflow channel cannot pass the stop 310 smoothly and enter the outflow channel. This alternating release device can effectively prevent the package on the branch conveyor line 200 from colliding with the package on the main conveyor line 100 when it enters the main conveyor line 100, thereby avoiding congestion and blockage of the package at the intersection.

[0025] As a preferred embodiment, please refer to Figure 2 The branch conveyor line 200 is perpendicular to the main conveyor line 100. When a package on one of the inflow channels pushes the corresponding stop 310 to move, the locking mechanism 400 can be triggered.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3 The stop 310 corresponding to the main conveyor line 100 is located upstream of the stop 310 corresponding to the branch conveyor line 200, so that the two stops 310 do not interfere when switching between blocking or releasing states.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 The cross-type dual-channel conveyor alternating release device further includes a support 500. The support 500 is disposed on the side of the junction of the main conveyor line 100 and the branch conveyor line 200, and is located in the upstream section of the main conveyor line 100. One end of each of the two stops 310 is rotatably connected to the support 500, and each can reciprocate around its rotation axis 311 in the horizontal plane. During the reciprocating rotation of the two stops 310 around its rotation axis 311, they can switch between blocking and releasing states. One end of each of the two first elastic elements 320 is connected to the support 500, and the other end of each of the two first elastic elements 320 is connected to the two stops 310 one-to-one. The support 500 can support the two stops 310, so that the two stops 310 can rotate around its rotation axis 311, which facilitates the switching of the stops 310 between blocking and releasing states.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 The locking mechanism 400 includes two locking components 410. One end of each locking component 410 slides against the two stops 310. As the packaging box in the inflow channel pushes the corresponding stop 310 to rotate downstream around its rotation axis 311, the stop 310 can push the locking component 410 that slides against it to move, so that the other end of the locking component 410 engages with the other stop 310, so that the other stop 310 is in a locked state. At this time, when the packaging box in the other inflow channel reaches the corresponding stop 310, it cannot push the corresponding stop 310 to move, and the packaging box in the inflow channel cannot smoothly pass the stop 310 and enter the outflow channel.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4Both of the aforementioned baffles 310 include a rotating shaft 311, a baffle rod 312, a chuck 313, and a semi-ring 314. The rotating shaft 311 is vertically arranged, and both its upper and lower ends are rotatably connected to the bracket 500. The baffle rod 312 is horizontally arranged, and one end of the baffle rod 312 is fixedly connected to the rotating shaft 311. The baffle rod 312 is used to block or allow packaging boxes flowing into the channel. The chuck 313 and the semi-ring 314 are respectively arranged on both sides of the baffle rod 312 and are coaxially fixedly sleeved on the rotating shaft 311. The first elastic element 320 One end of the first elastic element 320 is connected to the bracket 500, and the other end of the first elastic element 320 is connected to the chuck 313, so that the stop bar 312 is in a blocking state. When both stop bars 312 are in a blocking state, one end of each of the two locking components 410 slides against the ends of the two semi-rings 314. During the rotation of one of the rotating shafts 311, the corresponding semi-ring 314 can push the locking component 410 that slides against it to move, so that the other end of the locking component 410 engages with the other chuck 313. In the initial position, the two Each of the aforementioned baffles 312 is in a blocking state under the action of the corresponding first elastic member 320. When a package on one of the inflow channels reaches the corresponding baffle 310, it pushes the corresponding baffle 312 to rotate downstream, thereby putting the baffle 312 into a releasing state. The package passes the baffle 312 and enters the outflow channel. After the package passes the baffle 312, the baffle 312 resets under the action of the corresponding first elastic member 320 and is in a blocking state again. This is because when the package on the inflow channel pushes the corresponding baffle... When rod 312 rotates downstream, it will drive the rotating shaft 311 and the semi-ring 314 to rotate. The semi-ring 314 can push the locking component 410, which slides against it, to move, so that the other end of the locking component 410 is engaged with another chuck 313, thereby locking the other stop rod 312. At this time, when another package in the inflow channel reaches the corresponding stop rod 312, it cannot push the corresponding stop rod 312 to move, and the package in the inflow channel cannot smoothly pass the stop rod 312 and enter the outflow channel.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 3 When the baffle 312 is in the blocking state, the baffle 312 is perpendicular to the conveying direction of the inflow channel, so that the baffle 312 can effectively block the packaging boxes in the inflow channel.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 4The two stops 310 are staggered so that the two chucks 313 correspond to the two semi-rings 314 in an alternating manner. The two locking components 410 are staggered and located between the corresponding chucks 313 and semi-rings 314, respectively, to avoid interference between the two locking components 410.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 4 The first elastic element 320 is a first torsion spring, which is sleeved on the rotating shaft 311. Under the action of the first torsion spring, the stop bar 312 can always be in a blocking state when it is not subjected to external force.

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 4 Both ends of the two semi-rings 314 are sloping structures. When the semi-rings 314 rotate with the rotating shaft 311, one end of the locking component 410 can slide along the slope at the end of the semi-rings 314 onto the semi-rings 314. Since the diameter of the semi-rings 314 is larger than the diameter of the rotating shaft 311, when one end of the locking component 410 slides against the semi-rings 314, the other end of the locking component 410 engages with another chuck 313.

[0034] As a preferred embodiment, please refer to Figure 3 and Figure 4The chuck 313 has a groove 3131 on its arc-shaped wall. Both locking components 410 include a pin 411, a locking rod 412, and a second elastic element 413. The pin 411 is vertically positioned, and one end of the pin 411 is fixedly connected to the bracket 500. The locking rod 412 is horizontally positioned and corresponds to the chuck 313 and the semi-ring 314. The middle part of the locking rod 412 is rotatably sleeved on the other end of the pin 411. One end of the second elastic element 413 is connected to the bracket 500, and the other end of the second elastic element 413 is connected to the locking rod 412, so that one end of the locking rod 412 slides against the semi-ring 314. When the two locking rods 310... When both 12 are in the blocking state, one end of each of the two locking rods 412 slides and abuts against the ends of the two semi-rings 314. During the rotation of one of the rotating shafts 311, the corresponding semi-ring 314 can push the locking rod 412 that slides against it to rotate around the pin 411, so that the other end of the locking rod 412 abuts into the slot 3131 on the other chuck 313. In the initial position, both blocking rods 312 are in the blocking state under the action of the corresponding first elastic member 320. When one of the packaging boxes in the inflow channel reaches the corresponding stop member 310, it will push the corresponding blocking rod 312 to rotate downstream, thereby causing the blocking rod 312 to... In the release state, the packaging box passes the baffle 312 and enters the outflow channel. After the packaging box passes the baffle 312, the baffle 312 resets under the action of the corresponding first elastic element 320 and is in the blocking state again. Since when the packaging box in the inflow channel pushes the corresponding baffle 312 to rotate downstream, it will drive the rotating shaft 311 and the half ring 314 to rotate. One end of the locking rod 412 can slide along the slope at the end of the half ring 314 onto the half ring 314. Since the diameter of the half ring 314 is larger than the diameter of the rotating shaft 311, when one end of the locking rod 412 slides along the slope at the end of the half ring 314 onto the half ring 314, the locking rod 412 will... Rotating around the pin 411 allows the other end of the locking rod 412 to engage in the slot 3131 on another chuck 313, thereby locking the other stop rod 312. At this time, when another package in the inflow channel reaches the corresponding stop rod 312, it cannot push the corresponding stop rod 312 to move, and the package in the inflow channel cannot smoothly pass the stop rod 312 and enter the outflow channel. When one of the package in the inflow channel passes the stop rod 312, the stop rod 312 is reset under the action of the corresponding first elastic member 320, and the locking rod 412 is reset under the action of the corresponding second elastic member 413.

[0035] As a preferred embodiment, please refer to Figure 3 and Figure 4 The second elastic element 413 is a second torsion spring, which is sleeved on the pin 411. Under the action of the second torsion spring, when the stop bar 312 is in the blocking state, one end of the locking bar 412 can always abut against the junction of the half ring 314 and the rotating shaft 311.

[0036] As a preferred embodiment, please refer to Figure 2 The cross-type dual-channel conveyor alternating release device further includes a guiding mechanism 600. The guiding mechanism 600 is located on the side of the junction of the main conveyor line 100 and the branch conveyor line 200, and is located in the downstream section of the main conveyor line 100. It is used to slide against the packaging boxes on the branch conveyor line 200 so that the packaging boxes on the branch conveyor line 200 can enter the main conveyor line 100. Since the path trajectory of the packaging boxes on the branch conveyor line 200 into the main conveyor line 100 is an arc, the guiding mechanism 600 can guide the movement of the packaging boxes, so that the packaging boxes can smoothly enter the main conveyor line 100.

[0037] As a preferred embodiment, please refer to Figure 2 The guiding mechanism 600 includes a support 610, a main shaft 620, and a rotating wheel 630. The main shaft 620 is vertically arranged, and its lower end is fixedly connected to the support 610. The rotating wheel 630 is rotatably sleeved on the upper end of the main shaft 620. The rotating wheel 630 is used to slide against the packaging boxes on the branch conveyor line 200. When the packaging boxes on the branch conveyor line 200 enter the main conveyor line 100, they will abut against the rotating wheel 630, thereby applying a force to the rotating wheel 630, causing the rotating wheel 630 to rotate. The rotating wheel 630 will push the packaging boxes downward in the opposite direction.

[0038] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below:

[0039] Initially, both baffles 312 are in a blocking state under the action of the corresponding first elastic element 320. When a package in one of the inflow channels reaches the corresponding baffle 312, it pushes the baffle 312 to rotate downstream, thus putting the baffle 312 in a releasing state. The package passes the baffle 312 and enters the outflow channel. After the package passes the baffle 312, the baffle 312 resets under the action of the corresponding first elastic element 320 and is in a blocking state again. Since the package in the inflow channel pushes the corresponding baffle 312 to rotate downstream, it will drive the rotating shaft 311 and the semi-ring 314 to rotate. One end of the locking rod 412 can slide along the slope at the end of the semi-ring 314 onto the semi-ring 314. Since the diameter of the semi-ring 314 is larger than the diameter of the rotating shaft 311, one end of the locking rod 412 slides along the slope at the end of the semi-ring 314 onto the semi-ring 314. When the lock rod 412 rotates around the pin 411, the other end of the lock rod 412 can be engaged in the slot 3131 on another chuck 313, thereby locking the other stop rod 312. At this time, when the package in another inflow channel reaches the corresponding stop rod 312, it cannot push the corresponding stop rod 312 to move. The package in the inflow channel cannot pass the stop rod 312 smoothly and enter the outflow channel. When the package in one of the inflow channels passes the stop rod 312, the stop rod 312 is reset under the action of the corresponding first elastic member 320, and the lock rod 412 is reset under the action of the corresponding second elastic member 413. This alternating release device can effectively prevent the package in the branch conveyor line 200 from colliding with the package in the main conveyor line 100 when it enters the main conveyor line 100, thereby avoiding congestion and blockage of the package at the intersection.

[0040] The cross-type dual-channel conveyor line alternating release device provided by this utility model has the following beneficial effects:

[0041] (1) This alternating release device can realize alternating release. When one of the packing boxes in the inflow channel pushes the corresponding baffle 312 to rotate downstream, the locking mechanism 400 can be triggered to lock the other baffle 312. The packing box in the other inflow channel cannot push the corresponding baffle 312 to rotate downstream, and the packing box in the other inflow channel cannot cross the corresponding baffle 312 to enter the outflow channel.

[0042] (2) In this alternating release device, the action of the stop bar 312 is driven only by the packaging boxes and elastic parts on the conveyor line. There is no need to set up a driving component or a monitoring system. The alternating release of packaging boxes can be achieved solely by the mechanical structure.

[0043] (3) This alternating release device can effectively prevent the packaging boxes on the branch conveyor line 200 from colliding with the packaging boxes on the main conveyor line 100 when they enter the main conveyor line 100, thereby avoiding congestion and blockage of the packaging boxes at the intersection.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
