Obviously, the described embodiments only represent some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application.

[0038] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0039] As Figs. 1-4The utility model discloses a kind of transport systems, transport system includes: track 1, track 1 is set along material conveying direction;Transport unit 2, several transport units 2 movably be located on track 1, transport unit 2 includes the carrying article 6 for carrying material;Driving unit;Stop unit, stop unit is located at the stop position of track 1;Transport system further includes detector located at stop position, detector is used to detect the quantity of transport unit 2 passing through stop position;Wherein, when transport system is in material conveying state, stop unit and transport unit 2 avoid setting, driving unit exerts first force to transport unit 2, first force is set towards material conveying direction;When transport system is in stop state, stop unit is located on the movement path of transport unit 2, and cut off the movement path of transport unit 2.

[0040] The utility model includes track 1 set along material conveying direction, transport unit 2 movably be located on track 1, transport unit 2 includes the carrying area for carrying material, stop unit is located at the stop position of track 1;When transport system is in stop state, stop unit is located on the movement path of transport unit 2, and cut off the transport path of transport unit 2, so that transport unit 2 cannot continue to move towards material conveying direction under the hindrance of stop unit;When transport system is in material conveying state, stop unit and transport unit 2 avoid setting, stop unit no longer hinders the movement of transport unit 2 on track 1, driving unit exerts first force to transport unit 2, first force makes transport unit 2 move towards material conveying direction;Because stop unit is located at stop position, when the set amount of material needs to be output, stop unit is controlled by operator or controller connected with stop unit signal, so that stop unit and transport unit 2 avoid setting, make transport unit 2 can pass through stop position, and move towards material conveying direction, after detector finds, after the set quantity of material passing through stop position, operator or controller makes stop unit cut off the movement path of transport unit 2, prevent transport unit 2 and material from outputting from stop position again, so as to not only realize automatic feeding, but also realize accurate feeding.

[0041] The utility model discloses a transportation system can be used for clothing or steel material and the transportation of many types of material.According to the track of the material conveying direction, the track 1 can be set as a straight line or a variety of shapes such as an arc.According to the different conveying materials, the carrying object 6 can be correspondingly selected in different structures, for example, if the material is clothing, the carrying object 6 can be a hook; if the material is steel, the carrying object 6 can be a tray for supporting steel, as long as the carrying object 6 can meet the current material transportation requirements. The stop unit can be understood as stopping the movement of the transportation unit 2 downstream, that is, in the direction of material conveying, which includes the following cases: ① the stop unit blocks the movement path of the transportation unit 2 to prevent the transportation unit 2 from passing the stop position; ② the stop unit removes the power of the transportation unit 2 moving on the track 1, so that the transportation unit 2 cannot pass the stop position; ③ the stop unit blocks the movement path of the transportation unit 2 while removing the power of the transportation unit 2 moving on the track 1, so that the transportation unit 2 can be accurately stopped at the stop position. When the stop unit blocks the transportation path of the transportation unit 2, it can completely block the movement channel of the stop position transportation unit 2 to realize the isolation of the movement path of the transportation unit 2, or it can not completely block the movement channel of the stop position transportation unit 2, but it can prevent the transportation unit 2 from moving in the direction of material conveying.

[0042] In the utility model, the stop unit and the driving unit are arranged to avoid each other, that is, the functions of the driving unit and the stop unit do not affect each other. Specifically: when the transportation unit 2 needs to move in the direction of material conveying, the stop unit is arranged to avoid the transportation unit 2, and the stop unit does not hinder the driving of the transportation unit 2 by the driving unit, so that the transportation unit 2 can move in the direction of material conveying under the first action force generated by the driving unit. When the transportation unit 2 needs to stop at the stop position to prevent the transportation unit 2 from passing the stop position and continuing to move in the direction of material conveying, the driving unit does not hinder the realization of the above functions of the stop unit, and the stop unit can smoothly isolate the movement path of the transportation unit 2 from the stop position to the direction of material conveying, preventing the transportation unit 2 from moving in the direction of material conveying. The transportation unit 2 is movably arranged on the track 1, which means that the transportation unit 2 and the track 1 are in sliding cooperation in the direction of material conveying, or the transportation unit 2 and the track 1 are in rolling cooperation in the direction of material conveying.

[0043] The driving unit has various forms of arrangement. For example, if the track 1 is full of the transport units 2, the driving unit can be arranged at the track 1 loading position, the transport units 2 are transferred to the track 1 loading position by other loading equipment, and then the driving unit pushes the transport units 2 in the feeding direction. At this time, the transport units 2 and the track 1 are in sliding or rolling fit. Since the track 1 is full of the transport units 2, when the driving unit pushes the transport units 2 at the track 1 loading position in the feeding direction, the transport units 2 close to the upstream will push the transport units 2 downstream to move in the feeding direction, thereby realizing the conveying of the material. At this time, the driving unit can be only one, so that the conveying of multiple transport units 2 is realized by one driving unit, thereby reducing the transportation cost. Specifically, it can be a pneumatic cylinder, or an electric push rod, etc. linear driving device.

[0044] Alternatively, a driving unit can also be arranged on each transport unit 2, and the movement and stop of the transport unit 2 on the track 1 in the feeding direction are realized by starting the driving unit on the corresponding transport unit 2. At this time, the transport unit 2 is provided with a roller in rolling fit with the track 1, and the driving unit is a rotary driving device arranged on the transport unit 2 and capable of driving the roller to rotate, such as a servo motor or other rotary motor. At this time, the stopping unit includes the driving unit.

[0045] Alternatively, the driving unit can not adopt the above structure, and the driving unit comprises a transmission assembly 3 and a first driving assembly, the first driving assembly is in transmission connection with the transmission assembly 3, the transmission assembly 3 is arranged along the track 1, and a plurality of first transmission members 4 are arranged on the transmission assembly 3 and are spaced apart in the conveying direction; the transportation unit 2 comprises a second transmission member 5, the second transmission member 5 is connected with the object carrying member 6, and the object carrying member 6 is connected with the transmission unit which is in sliding cooperation or rolling cooperation with the track 1 in the conveying direction, and the transmission unit can be a roller or a sliding block; when the transportation system is in the conveying state, the first transmission member 4 abuts against the second transmission member 5, the first transmission member 4 is located on the side of the second transmission member 5 away from the conveying direction, and the first transmission member 4 applies a first force to the second transmission member 5. The transmission assembly 3 can be a transmission belt, a transmission chain, or a sliding block, etc., which can move the first transmission member 4 in the conveying direction when the first driving member is started. According to the type of the transmission assembly 3, the first driving assembly is correspondingly selected in different types, for example, if the transmission assembly 3 is a belt or a chain, the first driving assembly can be a rotary motor or other rotary driving device, and if the transmission assembly 3 is a sliding block in sliding cooperation with the track 1, the first driving assembly is a cylinder or other linear driving device. The interval between the first transmission members 4 can be set according to the volume of the transportation unit 2 and the interval between adjacent transportation units 2, so that when the transportation system is in the conveying state, each first transmission member 4 can drive a transportation unit 2 to move in the conveying direction through the abutment with the second transmission member 5. The first transmission member 4 can be a lever extending from the transmission assembly 3 to the transportation unit 2, and the second transmission member 5 can be a structure that can maintain abutment with the first transmission member 4 and push the transportation unit 2 to move in the conveying direction when the transportation system is in the conveying state. The second transmission member 5 can be a part of the object carrying member 6 or an additional structure relative to the object carrying member 6, such as a plate or a block arranged on the object carrying member 6.

[0046] When the transportation system is in the stopping state, the first transmission member 4 is separated from the second transmission member 5. This makes the transportation unit 2 no longer driven by the driving unit when the transportation system is in the stopping state, and the power of the transportation unit 2 disappears, thereby reducing or even avoiding the problem that the transportation system cannot accurately feed materials when the transportation unit 2 easily breaks through the stopping unit and causes the transportation system to fail to accurately feed materials due to the continuous driving of the transportation unit 2 by the driving unit while the stopping unit blocks the movement path of the transportation unit 2.

[0047] When the transport system is in the stop state, the first transmission member 4 is disengaged from the second transmission member 5. There are various ways to achieve this function. For example, the second transmission member 5 is movably connected with the carrier 6. When the transport system is switched from the feeding state to the stop state, the stop unit applies a second force to the second transmission member 5 of the transport unit 2 located in the stop position. The second force makes the second transmission member 5 move away from the first transmission member 4 until the second transmission member 5 is disengaged from the first transmission member 4. This makes the transport unit 2 located in the stop position lose the connection with the driving unit, avoiding the problem that the transport unit 2 easily goes beyond the stop unit due to the continuous driving of the driving unit, and the transport system cannot accurately feed. In addition, this reduces the impact of the inertia of the transport unit 2 on the stop unit. The transport unit 2 further comprises a reset member. The reset member applies a third force to the second transmission member 5. The third force is arranged in the direction of approaching the first transmission member 4. The third force is smaller than the second force. After the transport system is switched from the stop state to the feeding state, the reset member can make the second transmission member 5 move in the direction of approaching the first transmission member 4, and then restore the abutment between the first transmission member 4 and the second transmission member 5. Thus, the first driving assembly can drive the transport unit 2 to move in the feeding direction through the transmission assembly 3 and the first transmission member 4.

[0048] As Figs. 1-4When the stopping unit blocks the movement path of the conveying unit 2 by releasing the power of the conveying unit 2 in the conveying direction, the stopping unit comprises a releaser, the releaser comprises a second stopping piece 13, and a driving device that drives the second stopping piece 13 to move towards the conveying unit 2 or away from the conveying unit 2, and the driving device can be a linear driving device such as an electric push rod or a pneumatic cylinder; when the conveying system is in the conveying state, the driving device drives the second stopping piece 13 to move away from the conveying unit 2, and the second stopping piece 13 is arranged to avoid the conveying unit 2; when the conveying system is in the stopping state, the driving device drives the second stopping piece 13 to move towards the conveying unit 2, specifically towards the second transmission piece 5, and the second stopping piece 13 applies a second force to the second transmission piece 5 of the conveying unit 2 in the stopping position. For example, when the second stopping piece 13 is driven by the driving device to rotate towards or away from the second transmission piece 5, one end of the second stopping piece 13 is rotatably connected to the track 1, and the other end of the second stopping piece 13 or other regions of the second stopping piece 13 except the one end are drivingly connected to the driving device; when the conveying system is in the stopping state, the output shaft of the driving device extends towards the conveying unit 2, the driving shaft drives the region of the second stopping piece 13 drivingly connected to the driving device to rotate towards the second transmission piece 5, and the second stopping piece 13 applies a second force to the second transmission piece 5; conversely, when the conveying system is in the conveying state, the driving device drives the second stopping piece 13 to rotate away from the second transmission piece 5, and the second stopping piece 13 releases the second force applied to the second transmission piece 5, so that the second transmission piece 5 can move towards the first transmission piece 4 under the action of the restoring piece, and the abutment between the second transmission piece 5 and the first transmission piece 4 is restored. When the second stopping piece 13 is driven by the driving device to move towards or away from the second transmission piece 5, the second stopping piece 13 is connected to the output shaft of the driving device. The second stopping piece 13 can be a stopping rod or a stopping hook; when the second stopping piece 13 is a stopping hook, one end of the stopping hook without a hook portion is connected to the track 1, and the other end of the stopping hook with a hook portion is drivingly connected to the driving device;

[0049] And / or, when the stop unit prevents the transport unit 2 from moving in the feeding direction beyond the stop position by partially or completely blocking the movement path of the transport unit 2, the stop unit comprises a driving device and a second stop piece 13, the stop piece and the driving device are arranged in the same way as described above, but the second stop piece 13 is a structure such as a blocking plate or a blocking block that can cover the movement path of the transport unit 2 at this time, when the transport system is in the feeding state, the driving device drives the second stop piece 13 to move away from the second transmission piece 5, the stop unit is located outside the movement path of the transport unit 2, and does not hinder the movement of the transport unit 2; when the transport system is in the stop state, the stop piece is driven by the driving device to move in the direction close to the movement path of the transport unit 2 (the movement includes rotation and movement), partially or completely blocks the transport path of the transport unit 2, and prevents the transport unit 2 from continuing to move in the feeding direction beyond the stop position, the second stop piece 13, and the connection between the second stop piece 13 and the driving device needs to have sufficient strength to ensure that the second stop piece 13 can withstand the impact of the transport unit 2.

[0050] The second transmission piece 5 is movably connected with the carrier 6, which includes the cases where the second transmission piece 5 is rotationally connected with the carrier 6 and the second transmission piece 5 is slidingly connected with the carrier 6. When the second transmission piece 5 is rotationally connected with the carrier 6, the reset piece includes a first counterweight 7 arranged on the side of the second transmission piece 5 facing the feeding direction, at this time, the second acting force is greater than the total weight of the first counterweight 7 and the second transmission piece 5, the first counterweight 7 enables the second transmission piece 5 to rotate in the direction close to the first transmission piece 4, or the first counterweight 7 can be omitted, and the second transmission piece 5 has sufficient weight to drive the second transmission piece 5 to rotate in the direction close to the first transmission piece 4.

[0051] As shown in Figs. 1-4 The reset piece further includes a reset plate 8 rotationally connected with the carrier 6, the reset plate 8 is located on the side of the second transmission piece 5 away from the feeding direction, the side of the reset plate 8 facing the feeding direction is provided with a first abutting portion 9, the side of the second transmission piece 5 away from the feeding direction is provided with a second abutting portion 10, the first abutting portion 9 abuts against the second abutting portion 10, and the second abutting portion 10 is located above the first abutting portion 9, and the side of the reset plate 8 away from the feeding direction is further provided with a second counterweight 11, or the second counterweight 11 can be omitted, and the reset plate 8 has sufficient weight to drive the second transmission piece 5 to rotate in the direction close to the first transmission piece 4. The first counterweight 7 and the second counterweight 11 can be counterweight blocks or other structures with a certain weight. On the one hand, the second counterweight 11 enables the reset plate 8 to drive the second transmission piece 5 to rotate in the direction close to the first transmission piece 4 when the transport system switches from the stop state to the feeding state, and then the second transmission piece 5 and the first transmission piece 4 abut against each other to restore the movement of the transport unit 2 in the feeding direction; on the other hand, the second counterweight 11 should not be arranged too large to intensify the friction between the second transmission piece 5 and the first transmission piece 4.

[0052] The reset member further comprises a first torsion spring arranged at the connecting position between the second transmission member 5 and the carrying member 6, and the first torsion spring enables the second transmission member 5 to rotate towards the first transmission member 4; and a second torsion spring arranged at the connecting position between the reset plate 8 and the carrying member 6, and the second torsion spring enables the reset plate 8 to rotate towards the side away from the feeding direction. Since the first abutting portion 9 is below the second abutting portion 10, when the reset plate 8 rotates towards the side away from the feeding direction, the second transmission member 5 is enabled to rotate towards the first transmission member 4 until the second transmission member 5 and the first transmission member 4 abut.

[0053] When the second transmission member 5 is movable relative to the carrying member 6, the reset member comprises an elastic member such as a spring arranged between the second transmission member 5 and the carrying member 6, and the elastic member applies a third force to the second transmission member 5. If the second transmission member 5 is a transmission rod sliding relative to the carrying member 6, and the second transmission member 5 is arranged from top to bottom, the second stop member 13 needs to be arranged vertically or obliquely relative to the feeding direction, so that the second stop member 13 can be driven by the driving device to push the second transmission member 5 to move away from the first transmission member 4.

[0054] The transport unit 2 further comprises a first stop member 12 arranged at the side of the second transmission member 5 away from the feeding direction, and the first stop member 12 is connected to the carrying member 6. When the second transmission member 5 of the upstream transport unit 2 contacts the first stop member 12 of the downstream transport unit 2, the first stop member 12 applies a fourth force to the second transmission member 5, and the fourth force enables the second transmission member 5 to move away from the first transmission member 4. At this time, the stop unit further comprises the first stop member 12. By arranging the first stop member 12, after the transport unit 2 at the stop position is stopped under the action of the stop unit, the downstream first stop member 12 can enable the upstream transport unit 2 to be disconnected from the transmission connection with the driving unit. That is, by the cooperation of the first stop member 12 and the stop unit, the transport unit 2 at the stop position away from the feeding direction on the track 1 can be stopped, further reducing the impact of the transport unit 2 on the stop unit, and ensuring the accuracy of the feeding of the transport system.

[0055] As Figs. 1-4As shown, when the second transmission member 5 and the carrying member 6 are rotationally connected, the first stop member 12 can be a stop inclined surface (the inclination angle of the stop inclined surface is set according to the working condition, for example, it can be °), and the end of the stop inclined surface close to the downstream conveying unit 2 is higher than the end of the stop inclined surface away from the downstream conveying unit 2. Alternatively, the first stop member 12 can also be other structures that can make the second transmission member 5 of the subsequent conveying unit 2 rotate away from the first transmission member 4 after the first stop member 12 of the previous conveying unit 2 contacts the second transmission member 5 of the subsequent conveying unit 2, such as a stop wedge; the previous conveying unit 2 can be understood as the conveying unit 2 closer to the stop position among the conveying units 2 facing away from the feeding direction at the stop position, and the previous conveying unit 2 and the subsequent conveying unit 2 refer to two adjacent conveying units 2.

[0056] When the second transmission member 5 and the carrying member 6 are slidably connected, the first stop member 12 can be a stop block.

[0057] The conveying unit 2 further comprises a limiting member 14, which is arranged on the movement track of the second transmission member 5 and is located on the side of the second transmission member 5 away from the first transmission member 4. The limiting member 14 prevents the second transmission member 5 from moving too much, which makes it difficult for the resetting member to reset the second transmission member 5 to abut against the first transmission member 4. According to the different connection modes of the second transmission member 5 and the carrying member 6, the limiting member 14 has different setting structures. When the second transmission member 5 and the carrying member 6 are rotationally connected, the limiting member 14 can be a limiting rod arranged on the rotation track of the second transmission member 5, so as to prevent the second transmission member 5 from rotating too much, which makes it difficult for the resetting member to reset the second transmission member 5 to abut against the first transmission member 4; when the second transmission member 5 and the carrying member 6 are slidably connected, the limiting member 14 can be a limiting block arranged in the second transmission member 5 or the carrying member 6, which prevents the second transmission member 5 from moving too much away from the first transmission member 4.

[0058] The second transmission member 5 extends along the feeding direction or a direction obliquely arranged with respect to the feeding direction, which specifically means that the width of the second transmission member 5 in the direction from the side of the second transmission member 5 close to the first transmission member 4 to the side of the second transmission member 5 away from the first transmission member 4 is greater than the width of the second transmission member 5 in the direction perpendicular to the first direction, which reduces the area of the contact region of the second transmission member 5 and the first transmission member 4, so that the first transmission member 4 and the second transmission member 5 are less likely to be stuck, but it should be noted that the contact region of the second transmission member 5 and the first transmission member 4 cannot be too small, so as to ensure that the function of the first transmission member 4 stably driving the second transmission member 5 and the conveying unit 2 to move in the feeding direction can be smoothly realized; the first direction refers to the direction from the side of the second transmission member 5 close to the first transmission member 4 to the side of the second transmission member 5 away from the first transmission member 4.

[0059] Further, the utility model discloses the discharge position on the track 1 is equipped with, and discharge position and stop position are arranged along the material conveying direction in proper order, and the interval between stop position and discharge position is not less than the length of transport unit 2 in the material conveying direction, and discharge position is equipped with stop unit.

[0060] Further, the utility model discloses the discharge position on the track 1 is equipped with, and discharge position and stop position are arranged along the material conveying direction in proper order, and the interval between stop position and discharge position is not less than the length of transport unit 2 in the material conveying direction, and discharge position is equipped with stop unit.
