[0036] With reference to the accompanying drawings, Figure 1 It is a schematic diagram of the main structure of the barrier and the conveying system of the present invention; Figure 2 It is a schematic diagram of the front cross-sectional structure of the barrier and the conveying system thereof of the present invention; Figure 3 It is a left-side structural schematic diagram of the present invention in a blocking state; Figure 4 It is a left-side structural schematic diagram of the present invention in the released state.

[0037] In a specific embodiment, Figures 1 to 4 As shown, a blocker is arranged on the track 7 on which the hanger 6 runs, and blocks the hanger 6, comprising a blocking mechanism and a driving mechanism, wherein the blocking mechanism is provided with a passage space, and the blocking mechanism comprises a first blocking needle 1 and a second blocking needle 2, the first blocking needle 1 and the second blocking needle 2 are relatively arranged in the passage space, and the blocking mechanism has at least a blocking state and a releasing state, when the blocking mechanism is in the blocking state, the first blocking needle 1 is in contact with the hanger 6 to limit the position, and the second blocking needle 2 is out of contact with the hanger 6, so that the operation of the hanger 6 is blocked and cannot be transported on the track 7, and then the products are arranged on the track 7 in sequence, so that the products on the hanger 6 are stored on the track, when the blocking mechanism is in the releasing state, the first blocking needle 1 is out of contact with the hanger 6, and the second blocking needle 2 is in contact with the subsequent hanger 6 to limit the position, and the hanger 6 to be released is out of contact with the first blocking needle 1 to be transported on the track 7, and the driving mechanism is used to drive the blocking mechanism to switch between the blocking state and the releasing state.

[0038] It should be understood that the first stop needle 1 can be abutted against the side wall of the hanger 6, or can be inserted into a groove or a through hole opened on the hanger 6. As long as the hanger 6 can be limited, it belongs to the protection scope of the present invention; the blocking mechanism can be set to a rotational motion or a linear motion, etc., as long as the switching between the blocking state and the release state can be realized, it belongs to the protection scope of the present invention.

[0039] The first stop needle 1 is limited by the abutment with the hanger 6, so that the hanger 6 cannot be transported on the track 7, and is then arranged in sequence on the track 7. The products on the hanger 6 are stored on the track, making full use of the longitudinal space and saving floor space. When the hanger 6 needs to be released, the blocking mechanism is driven by the driving mechanism, so that the first stop needle 1 is disengaged from the hanger 6, and the second stop needle 2 is limited by the abutment with the subsequent hanger 6, preventing the subsequent hanger 6 from passing through while ensuring that the required products on the hanger 6 are smoothly transported with the hanger 6, avoiding manual removal, storage and taking out of the products according to demand, improving the degree of automation and saving human resources.

[0040] In a specific embodiment of the present invention, Figures 1 to 4 As shown, in order to enable the driving mechanism to drive the first stop needle 1 and the second stop needle 2 at the same time, the blocking mechanism also includes a connecting seat assembly 3, which is rotatably arranged on the track 7, and the rotation plane of the connecting seat assembly 3 is perpendicular to the conveying direction of the track 7. The first stop needle 1 and the second stop needle 2 are installed on two opposite sides of the connecting seat assembly 3, and based on the reciprocating swing of the connecting seat assembly 3, the blocking mechanism is switched between the blocking state and the releasing state.

[0041] It should be understood that Figure 3 and Figure 4 As shown, the installation method of the connecting seat assembly 3 being rotatably set on the track 7 can also be replaced by installing it on the track 7 in a linear motion manner. The linear motion manner can be set to sliding motion or rolling motion, etc. As long as the connecting seat assembly 3 can move left and right within the above-mentioned rotation plane, it belongs to the protection scope of the present invention.

[0042] In a specific embodiment of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, it also includes a mounting member 4, which is installed on the track 7 and is used to install a driving mechanism. The connecting seat assembly 3 is rotatably set on the track 7. The driving mechanism is configured as a telescopic mechanism 5 installed on the mounting member 4. The telescopic end of the telescopic mechanism 5 passes through the mounting member 4 and is connected to the connecting seat assembly 3. The connecting seat assembly 3 is driven to swing back and forth based on the telescopic end of the telescopic mechanism 5. The telescopic mechanism 5 can be configured as a cylinder or a hydraulic cylinder, etc. As long as the connecting seat assembly 3 can be driven to swing back and forth through the telescopic end, it belongs to the protection scope of the present invention.

[0043] Specifically, a sliding member slidable in a height direction is provided on the side wall of the connecting seat assembly 3, and the telescopic end of the telescopic mechanism 5 is hinged to the sliding member.

[0044] It should be understood that the driving mechanism may also be provided with a rotating motor, etc., and as long as it can drive the connecting seat assembly 3 to rotate, it belongs to the protection scope of the present invention.

[0045] Specifically, if Figures 1 to 4 As shown, the connecting seat assembly 3 is rotatably installed on the track 7. The connecting seat assembly 3 includes two connecting seats 301, a rotating member and a sliding member. Along the conveying direction of the track 7, the two connecting seats 301 are installed on the track 7 at intervals. The rotating member is rotatably connected between the two connecting seats 301, and the rotating plane of the rotating member is perpendicular to the conveying direction of the track 7. The rotating member is an inverted U-shaped structure, including a top plate 302, a first side plate 303 and a second side plate 304. In order to facilitate the maintenance and replacement of the first side plate 303 and the second side plate 304 In exchange, the first side plate 303 and the second side plate 304 are installed on two opposite sides of the top plate 302 by screws, and are located on the left and right sides of the track 7. In order to facilitate the maintenance and replacement of the first stop needle 1 and the second stop needle 2, the first stop needle 1 is detachably installed on the first side plate 303, and the second stop needle 2 is detachably installed on the second side plate 304. The mounting member 4 is arranged on the same side as the first side plate 303. A sliding block is slidably installed on the first side plate 303 toward one side of the telescopic mechanism 5, and the telescopic end of the telescopic mechanism 5 is hingedly connected to the sliding block.

[0046] It should be understood that the rotating member may also be an integrally formed inverted U-shaped structure, the first stopper needle 1 may also be fixedly mounted on the first side plate 303 , and the second stopper needle 2 may also be fixedly mounted on the second side plate 304 .

[0047] Specifically, when the connecting seat assembly 3 is installed on the track 7 in a linear motion manner, the driving mechanism can be set to a worm gear transmission mechanism or a telescopic mechanism 5, etc. As long as it can drive the connecting seat assembly 3 to perform linear reciprocating motion, it belongs to the protection scope of the present invention. Optionally, in a specific embodiment of the present invention, the driving mechanism is set to a worm gear transmission mechanism, the connecting seat assembly 3 is connected to the worm, and the worm wheel is installed at the output end of the motor. The worm wheel is driven by the motor to rotate, and the linear motion of the worm is achieved based on the rotation of the worm wheel, thereby achieving linear reciprocating motion of the connecting seat assembly 3. Optionally, in another specific embodiment of the present invention, the driving mechanism is set to a telescopic mechanism 5, and the connecting seat assembly 3 is installed at the telescopic end of the telescopic mechanism 5. Based on the telescopic end of the telescopic mechanism 5, the connecting seat assembly 3 can perform linear reciprocating motion along the left and right sides of the track 7. The telescopic mechanism 5 can be set to a cylinder or a hydraulic cylinder, etc. As long as the connecting seat assembly 3 can be driven to swing back and forth by the telescopic end, it belongs to the protection scope of the present invention.

[0048] In a specific embodiment of the present invention, along the conveying direction of the track 7, the first stop needle 1 is arranged in front of the second stop needle 2, and the distance L between the first stop needle 1 and the second stop needle 2 is L≥Nl (N≥1), where l is the maximum width of the hanger 6 along the conveying direction of the track 7.

[0049] Optionally, along the conveying direction of the track 7, the distance L between the first stop needle 1 and the second stop needle 2 is l, which ensures that a hanger 6 is accommodated between the first stop needle 1 and the second stop needle 2. When the blocking mechanism is in the release state, Figure 4 As shown, the first stop needle 1 is separated from the hanger 6, and the second stop needle 2 abuts against the subsequent hanger 6. The hanger 6 between the first stop needle 1 and the second stop needle 2 is released and transported forward, ensuring that the blocking mechanism releases only one hanger 6 at a time.

[0050] It should be understood that when it is necessary to release one or more hangers 6 at the same time, it can be achieved by adjusting the distance between the first stop needle 1 and the second stop needle 2 or controlling the switching speed of the blocking state and the release state of the blocking mechanism. As long as the required hanger 6 can be released, it falls within the protection scope of the present invention.

[0051] In a specific embodiment of the present invention, the blocker also includes a control unit, and the driving mechanism is electrically connected to the control unit. The control unit can control the movement of the driving mechanism. By controlling the transport speed and movement cycle of the driving mechanism, the blocking and release of the required hanger 6 are achieved, thereby improving the degree of automation.

[0052] In a specific embodiment, a conveying system includes a track 7 and a blocker as described above.

[0053] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the conveying system also includes a track 7, a hanger 6 and a chain 8, wherein the hanger 6 is movably mounted on the track 7, the chain 8 is mounted on the track 7 and is located above the hanger 6, a plurality of friction members 9 are evenly arranged at the bottom of the chain 8, and in the height direction, the top of the hanger 6 is located between the bottom of the chain 8 and the bottom of the friction member 9, and based on the transmission of the chain 8, the friction member 9 pushes the hanger 6 to be conveyed in the track 7.

[0054] It should be understood that the chain 8 may also be replaced by a conveyor belt, etc., as long as the hanger 6 can be transported on the track 7 by driving the movement of the friction member 9, it belongs to the protection scope of the present invention.

[0055] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, in order to ensure the stability of the operation of the hanger 6, the track 7 is set as a U-shaped structure with an opening downward, and the two sides of the open end of the track 7 extend inward to form support bars 701. In the conveying direction perpendicular to the track 7, rolling elements 601 are provided on two opposite sides of the hanger 6, and the two rolling elements 601 are symmetrically arranged, and the rolling elements 601 and the support bars 701 roll in cooperation.

[0056] In a specific embodiment of the present invention, Figures 1 to 4As shown, along the conveying direction of the track 7, arc-shaped grooves 602 are provided on two opposite sides of the hanger 6, and the two arc-shaped grooves 602 are symmetrically arranged, the arc-shaped grooves 602 are adapted to the first stop needle 101 and the second stop needle 201, and a hanging hole 603 is provided at the bottom end of the hanger 6 for hanging products. When the blocking mechanism is in the blocking state, the first stop needle 1 is inserted into the arc-shaped groove 602 to realize the abutment and limitation of the first stop needle 1 on the hanger 6. When the blocking mechanism is in the releasing state, the second stop needle 2 is inserted into the subsequent arc-shaped groove 602 to realize the abutment and limitation of the second stop needle 2 on the subsequent hanger 6. Two arc-shaped grooves 602 are arranged on the hanger 6, which can make the first stop needle 1 or the second stop needle 2 smoothly inserted into the arc-shaped groove 602 in front of the blocked hanger 6 to block the hanger 6, and can also avoid the first stop needle 1 or the second stop needle 2 from colliding with the front unblocked hanger 6.

[0057] It should be understood that the hanger 6 may also be provided with through holes that match the first stopper needle 1 and the second stopper needle 2, etc. As long as blocking and releasing can be achieved, it belongs to the protection scope of the present invention.

[0058] The present invention provides a blocker and a conveying system thereof, taking the connection seat assembly 3 rotatably mounted on the track 7, the driving mechanism being configured as a telescopic mechanism 5, and the distance between the first block needle 1 and the second block needle 2 being the width of a hanger 6 as an example, the working process thereof is as follows: based on the transmission of the chain 8, the friction member 9 is used to push the hanger 6 to be conveyed in the track 7, and when the blocking mechanism is in the blocking state, such as Figure 3 As shown, the telescopic end of the telescopic mechanism 5 is in an extended state, the first stop needle 1 is inserted into the arc-shaped groove 602 of the hanger 6 for abutment limiting, and the second stop needle 2 is separated from the hanger 6. The operation of the hanger 6 is blocked by the blocking of the first stop needle 1, and the movement of the friction member 9 causes the hanger 6 to tilt toward one side of the first stop needle 1 with the central axis of the rolling member 601 as the center, until the top end of the hanger 6 drops to break contact with the friction member 9, thereby making the hangers 6 arranged in sequence on the blocking side of the first stop needle 1. When it is necessary to release a hanger 6 between the first stop needle 1 and the second stop needle 2, the control unit controls the telescopic end of the telescopic mechanism 5 to retract, thereby driving the connecting seat assembly 3 to rotate toward one side of the telescopic mechanism 5, so that the blocking mechanism reaches the release state, as shown in FIG. Figure 2 and Figure 4As shown, the first stop needle 1 is disengaged from the arc groove 602 of the hanger 6, and the second stop needle 2 is inserted into the arc groove 602 of the subsequent hanger 6. At this time, the subsequent hanger 6 is blocked on the blocking side of the second stop needle 2, and the hanger 6 between the first stop needle 1 and the second stop needle 2 is no longer blocked, and continues to be transported under the drive of the friction part 9. After the hanger 6 between the first stop needle 1 and the second stop needle 2 is transported to the release side of the first stop needle 1, the control unit controls the extension of the telescopic end of the telescopic mechanism 5, and then drives the driving connecting seat assembly 3 to rotate to the side away from the telescopic mechanism 5, so that the blocking mechanism reaches the blocking state, and the hanger 6 on the track 7 runs forward and abuts against the first stop needle 1 to limit the position, and the above steps are repeated to realize the release of the hangers 6 in sequence.

[0059] It should be understood that along the conveying direction of the track 7, the blocking side of the first stop needle 1 is the side on which the hanger 6 conveys toward the first stop needle 1, the releasing side of the first stop needle 1 is the side on which the hanger 6 conveys away from the first stop needle 1, and the blocking side of the second stop needle 2 is the side on which the hanger 6 conveys toward the second stop needle 2.

[0060] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0061] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
