DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0039] like Figure 1 to Figure 4 As shown, the present invention discloses a transportation system, which includes: a track 1, which is arranged along the feeding direction; a transportation unit 2, wherein a plurality of transportation units 2 are movably arranged on the track 1, and the transportation unit 2 includes a carrier 6 for carrying materials; a driving unit; a stop unit, and the stop unit is arranged at the stop position of the track 1; the transportation system also includes a detector arranged at the stop position, and the detector is used to detect the number of transportation units 2 passing through the stop position; wherein, when the transportation system is in the feeding state, the stop unit and the transportation unit 2 are arranged to avoid each other, and the driving unit applies a first force to the transportation unit 2, and the first force is arranged in the feeding direction; when the transportation system is in the stop state, the stop unit is located on the movement path of the transportation unit 2 and blocks the movement path of the transportation unit 2.

[0040] The present invention comprises a track 1 arranged along the feeding direction, a transport unit 2 movably arranged on the track 1, the transport unit 2 comprises a loading area for carrying materials, and a stop unit is arranged at the stop position of the track 1; when the transport system is in a stopped state, the stop unit is located on the moving path of the transport unit 2 and blocks the transport path of the transport unit 2, so that the transport unit 2 cannot continue to move in the feeding direction under the obstruction of the stop unit; when the transport system is in a feeding state, the stop unit and the transport unit 2 are arranged to avoid each other, the stop unit no longer obstructs the movement of the transport unit 2 on the track 1, and the driving unit applies a first The first force causes the transport unit 2 to move in the feeding direction; because the stop unit is in the stop position, when a set amount of material needs to be output, the stop unit is controlled by the operator or the controller connected to the stop unit signal, so that the stop unit and the transport unit 2 are arranged to avoid each other, so that the transport unit 2 can pass through the stop position and move in the feeding direction. After the detector finds that the set amount of material has passed through the stop position, the operator or the controller causes the stop unit to block the movement path of the transport unit 2 to prevent the transport unit 2 and the material from being output from the stop position again, thereby realizing not only automatic feeding but also accurate feeding.

[0041] Among them, the transportation system of the present invention can be used for the transportation of various types of materials such as clothing or steel. According to the trajectory of the feeding direction, the track 1 can be set to various shapes such as a straight line or an arc. According to the different materials to be transported, the object carrier 6 can choose different structures accordingly. For example, if the material is clothing, the object carrier 6 can be a hook; if the material is steel, the object carrier 6 can be a tray supporting the steel, as long as the object carrier 6 can meet the current material transportation needs. The stop unit blocks the movement path of the transport unit 2, which can be understood as the stop unit preventing the transport unit 2 from moving downstream, that is, in the feeding direction, which includes the following situations: ① The stop unit blocks the movement path of the transport unit 2 to prevent the transport unit 2 from crossing the stop position; ② The stop unit releases the power of the transport unit 2 to move on the track 1, so that the transport unit 2 cannot cross the stop position; ③ The stop unit blocks the movement path of the transport unit 2 and releases the power of the transport unit 2 to move on the track 1, so that the transport unit 2 can stop accurately at the stop position. When the stop unit blocks the transport path of the transport unit 2, it can either completely block the movement channel of the transport unit 2 at the stop to achieve the isolation of the movement path of the transport unit 2, or it can not completely block the movement channel of the transport unit 2 at the stop, but can prevent the transport unit 2 from moving in the feeding direction.

[0042] In the present invention, the stop unit and the driving unit are arranged to avoid each other, which means that the functions of the driving unit and the stop unit do not affect each other. Specifically: when the transport unit 2 needs to move in the feeding direction, the stop unit and the transport unit 2 are arranged to avoid each other, and the stop unit does not hinder the driving unit of the transport unit 2. The transport unit 2 can move in the feeding direction under the first force generated by the driving unit. When the transport unit 2 needs to stop at the stop position to prevent the transport unit 2 from crossing the stop position and continuing to move in the feeding direction, the driving unit will not hinder the realization of the above functions of the stop unit. The stop unit can smoothly block the movement path of the transport unit 2 from the stop position to the feeding direction to prevent the transport unit 2 from moving in the feeding direction. The transport unit 2 is movably arranged on the track 1, which means that the transport unit 2 and the track 1 are slidably matched in the feeding direction, or the transport unit 2 and the track 1 are rolling matched in the feeding direction.

[0043] The drive unit can be set in various forms. For example, if the track 1 is full of transport units 2, the drive unit can be set at the loading point of the track 1, and the transport unit 2 is transferred to the loading point of the track 1 through other loading equipment, and then the drive unit pushes the transport unit 2 in the feeding direction. At this time, the transport unit 2 and the track 1 are slidably matched or rolled. Because the track 1 is full of transport units 2, when the drive unit pushes the transport unit 2 at the loading point of the track 1 in the feeding direction, the transport unit 2 close to the upstream will push the downstream transport unit 2 to move in the feeding direction, thereby realizing the transportation of materials. At this time, only one drive unit can be set. In this way, the transportation of multiple transport units 2 is realized through one drive unit, which reduces the transportation cost. Specifically, it can be a linear drive device such as a cylinder or an electric push rod.

[0044] Alternatively, a driving unit may be provided on each transport unit 2, and the driving unit on the corresponding transport unit 2 is activated to realize the movement and stop of the transport unit 2 in the feeding direction on the track 1. In this case, the transport unit 2 is provided with rollers that roll with the track 1, and the driving unit is a rotary driving device provided on the transport unit 2 that can drive the rollers to rotate, such as a rotary motor such as a servo motor. In this case, the stopping unit includes the driving unit.

[0045] Alternatively, the driving unit may not adopt the above structure. The driving unit includes a transmission component 3 and a first driving component. The first driving component is connected to the transmission component 3 in a transmission manner. The transmission component 3 is arranged along the track 1. A plurality of first transmission members 4 are arranged on the transmission component 3 at intervals along the feeding direction. The transport unit 2 includes a second transmission member 5. The second transmission member 5 is connected to the object carrier 6, and a transmission unit connected to the object carrier 6 and slidingly or rollingly cooperating with the track 1 in the feeding direction. The transmission unit may be a roller or a slider. When the transport system is in the feeding 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 feeding direction, and the first transmission member 4 applies a first force to the second transmission member 5. The transmission component 3 may be a transmission belt, a transmission chain, a slider, etc., which can move the first transmission member 4 in the feeding direction when the first driving member is started. According to the type of the transmission assembly 3, the first drive assembly selects different types accordingly. For example, if the transmission assembly 3 is a belt or a chain, the first drive assembly can be a rotary drive device such as a rotary motor. If the transmission assembly 3 is a slider that slides with the track 1, the first drive assembly can be a linear drive device such as a cylinder. The interval between the first transmission members 4 can be set according to the volume of the transport unit 2 and the interval between adjacent transport units 2, so that when the transport system is in the transport state, each first transmission member 4 can drive a transport unit 2 to move in the feeding direction by abutting with the second transmission member 5. The first transmission member 4 can be specifically a lever extending toward the transport unit 2 on the transmission assembly 3, and the second transmission member 5 can be a structure that can maintain abutment with the first transmission member 4 when the transport system is in the transport state, and push the transport unit 2 to move in the feeding direction. The second transmission member 5 can be specifically a lever or a plate. At this time, the second transmission member 5 can be a part of the object carrier 6, or an additional structure relative to the object carrier 6, such as a plate or block provided on the object carrier 6.

[0046] When the transport system is in a stopped state, the first transmission member 4 is disengaged from the second transmission member 5. This means that after the transport system is in a stopped state, the transport unit 2 is no longer driven by the driving unit, and the power of the transport unit 2 disappears, thereby reducing or even avoiding the problem that when the driving unit continuously drives the transport unit 2, the stop unit blocks the movement path of the transport unit 2, and the transport unit 2 easily breaks through the stop unit, resulting in the inability of the transport system to accurately feed materials.

[0047] When the transport system is in a stopped state, the first transmission member 4 is disengaged from the second transmission member 5. There are many ways to implement this function. For example, the second transmission member 5 is movably connected to the object-carrying member 6. When the transport system switches from the feeding state to the stopped state, the stop unit applies a second force to the second transmission member 5 of the transport unit 2 located at the stopped position. The second force causes the second transmission member 5 to move in a direction away from the first transmission member 4 until the second transmission member 5 is disengaged from the first transmission member 4. This causes the transport unit 2 located at the stopped position to lose connection with the drive unit, thereby avoiding the problem that the transport unit 2 is easy to pass the stop unit due to the continuous driving of the drive unit, and the transport system cannot feed accurately. In addition, this reduces the impact of the inertia of the transport unit 2 on the stop unit. The transport unit 2 also includes a reset member, which applies a third force to the second transmission member 5. The third force is set in a direction close to the first transmission member 4, and the third force is smaller than the second force. After the transportation system switches from the stopped state to the feeding state, the reset member can make the second transmission member 5 move in the direction close to the first transmission member 4, and then restore the abutment between the first transmission member 4 and the second transmission member 5, so that the first drive component passes through the transmission component 3, and the first transmission member 4 can drive the transportation unit 2 to move in the feeding direction.

[0048] like Figure 1 to Figure 4As shown, when the stop unit blocks the movement path of the transport unit 2 by releasing the power of the transport unit 2 in the feeding direction, the stop unit includes a releaser, the releaser includes a second stop member 13, and a driving device that drives the second stop member 13 to move in a direction close to and away from the transport unit 2, and the driving device can be a linear driving device such as an electric push rod or a cylinder; when the transport system is in a transport state, the driving device drives the second stop member 13 to move in a direction away from the transport unit 2, and is arranged to avoid the transport unit 2. When the transport system is in a stop state, the driving device drives the second stop member 13 to move in a direction close to the transport unit 2, specifically close to the second transmission member 5, and applies a second force to the second transmission member 5 of the transport unit 2 in the stop position. For example, when the second stopper 13 rotates toward and away from the second transmission member 5 under the drive of the driving device, one end of the second stopper 13 is rotationally connected to the track 1, and the other end of the second stopper 13, or other areas except one end of the second stopper 13, are transmission-connected to the driving device. When the transport system is in a stopped state, the output shaft of the driving device extends toward the transport unit 2, and the driving shaft drives the area of ​​the second stopper 13 transmission-connected to the driving device to rotate toward the second transmission member 5, and applies a second force to the second transmission member 5. Conversely, when the transport system is in a transport state, the driving device drives the second stopper 13 to rotate away from the second transmission member 5, releases the second force applied to the second transmission member 5, and enables the second transmission member 5 to move toward the direction of approaching the first transmission member 4 under the action of the reset member, and restores the contact between the second transmission member 5 and the first transmission member 4. When the second stopper 13 moves toward and away from the second transmission member 5 under the drive of the driving device, the second stopper 13 is connected to the output shaft of the driving device. The second stop member 13 may be a stop rod or a stop hook. When the second stop member 13 is a stop hook, the end of the stop hook without the hook portion is connected to the track 1, and the end of the stop hook with the hook portion is in transmission connection with the driving device;

[0049] And / or, when the stop unit prevents the transport unit 2 from moving beyond the stop position toward the feeding direction by partially or completely blocking the movement path of the transport unit 2, the stop unit includes a driving device and a second stop member 13. The above-mentioned setting method of the stop member and the driving device is the same, but the second stop member 13 is now a blocking plate or a blocking block or other structure that can cover the movement path of the transport unit 2. When the transport system is in the feeding state, the driving device drives the second stop member 13 to move in a direction away from the second transmission member 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 member is driven by the driving device to move in a direction close to the movement path of the transport unit 2 (the movement includes rotation and movement), partially blocking or completely blocking the transport path of the transport unit 2, and preventing the transport unit 2 from continuing to move in the feeding direction beyond the stop position. The second stop member 13 and the connection between the second stop member 13 and the driving device need to be strong enough to ensure that the second stop member 13 can withstand the impact of the transport unit 2.

[0050] The second transmission member 5 is movably connected to the object carrier 6, which includes the case where the second transmission member 5 is rotationally connected to the object carrier 6, and the case where the second transmission member 5 is slidingly connected to the object carrier 6. When the second transmission member 5 is rotationally connected to the object carrier 6, the reset member includes a first counterweight member 7 disposed on the side of the second transmission member 5 facing the feeding direction. At this time, the second force is greater than the total weight of the first counterweight member 7 and the second transmission member 5. The first counterweight member 7 enables the second transmission member 5 to rotate in a direction close to the first transmission member 4. Alternatively, the first counterweight member 7 can be omitted so that the second transmission member 5 has sufficient weight to drive the second transmission member 5 to rotate in a direction close to the first transmission member 4.

[0051] like Figure 1 to Figure 4 As shown, the reset member also includes a reset plate 8 rotatably connected to the object carrier 6, the reset plate 8 is located on the side of the second transmission member 5 away from the feeding direction, the reset plate 8 is provided with a first abutment 9 on the side facing the feeding direction, the second transmission member 5 is provided with a second abutment 10 on the side away from the feeding direction, the first abutment 9 abuts against the second abutment 10, the second abutment 10 is located above the first abutment 9, and the reset plate 8 is further provided with a second counterweight 11 on the side away from the conveying direction, or the second counterweight 11 can be omitted, so that the reset plate 8 has enough weight and can be. The first counterweight 7 and the second counterweight 11 can be specifically a structure with a certain weight such as a counterweight block. On the one hand, the second counterweight 11 needs to enable the reset plate 8 to drive the second transmission member 5 to rotate in the direction close to the first transmission member 4 when the transportation system switches from the stopped state to the transportation state, thereby making the second transmission member 5 abut against the first transmission member 4 and restoring the movement of the transportation unit 2 in the feeding direction; on the other hand, the setting of the second counterweight 11 needs to not excessively aggravate the friction between the second transmission member 5 and the first transmission member 4.

[0052] Among them, the reset member also includes a first torsion spring arranged at the connection between the second transmission member 5 and the object carrier 6, the first torsion spring enables the second transmission member 5 to rotate in the direction close to the first transmission member 4; and a second torsion spring arranged at the rotation connection between the reset plate 8 and the object carrier 6, the second torsion spring is used to drive the reset plate 8 to rotate toward the side away from the feeding direction, and because the first abutment portion 9 is located below the second abutment portion 10, when the reset plate 8 rotates toward the side away from the feeding direction, it can drive the second transmission member 5 to rotate in the direction close to 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 can move relative to the object carrier 6, the reset member includes an elastic member such as a spring arranged between the second transmission member 5 and the object carrier 6, and a third force is applied to the second transmission member 5 through the elastic member; if the second transmission member 5 is a transmission rod that slides with the object carrier 6, and the second transmission member 5 is arranged from top to bottom, then the second stop member 13 needs to be arranged vertically or inclined relative to the feeding direction, so that the second stop member 13 can push the second transmission member 5 to move in a direction away from the first transmission member 4 under the drive of the driving device.

[0054] The transport unit 2 also includes a first stop member 12 disposed on the side of the second transmission member 5 away from the feeding direction, and the first stop member 12 is connected to the object carrier 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 causes the second transmission member 5 to move in a direction away from the first transmission member 4. At this time, the stop unit also includes the first stop member 12. By providing the first stop member 12, after the transport unit 2 located at the stop position stops under the action of the stop unit, the downstream first stop member 12 can release the transmission connection between the upstream transport unit 2 and the drive unit. In other words, through the cooperation of the first stop member 12 and the stop unit, the transport unit 2 located at the stop position away from the feeding direction on the track 1 can be stopped, which further reduces the impact of the transport unit 2 on the stop unit and ensures the accuracy of feeding of the transport system.

[0055] like Figure 1 to Figure 4As shown, when the second transmission member 5 and the object carrier 6 are rotationally connected, the first stop member 12 can be specifically a stop slope (the inclination angle of the stop slope is set according to the working conditions, for example, it can be °), and the end of the stop slope close to the downstream transport unit 2 is higher than the end of the stop slope away from the downstream transport unit 2. Alternatively, the first stop member 12 can also be other structures that can make the second transmission member 5 of the subsequent transport unit 2 rotate in the direction away from the first transmission member 4 after the first stop member 12 of the previous transport unit 2 contacts the second transmission member 5 of the subsequent transport unit 2, such as a stop wedge; the previous transport unit 2 can be understood as the transport unit 2 that is closer to the stop position among the many transport units 2 that deviate from the feeding direction at the stop position, and the previous transport unit 2 and the subsequent transport unit 2 refer to two adjacent transport units 2.

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

[0057] The transport unit 2 further includes a limiter 14, which is arranged on the motion track of the second transmission member 5, and the limiter 14 is located on the side of the second transmission member 5 away from the first transmission member 4. The limiter 14 prevents the second transmission member 5 from moving too much, which makes it difficult for the reset member to reset the second transmission member 5, so that the second transmission member 5 and the first transmission member 4 collide. According to the different connection modes of the second transmission member 5 and the object carrier 6, the limiter 14 has different setting structures. When the second transmission member 5 is rotationally connected with the object carrier 6, the limiter 14 can be a limiter rod arranged on the rotation track of the second transmission member 5 to prevent the second transmission member 5 from rotating too much, which makes it difficult for the reset member to reset the second transmission member 5 and collide with the first transmission member 4; when the second transmission member 5 is slidingly connected with the object carrier 6, the limiter 14 can be a limiter block arranged in the second transmission member 5 or the object carrier 6, which prevents the second transmission member 5 from moving excessively in the direction away from the first transmission member 4.

[0058] The second transmission member 5 extends along the feeding direction or along a direction inclined to the feeding direction. This specifically means that the width of the second transmission member 5 in the direction from the second transmission member 5 approaching the first transmission member 4 toward the direction from 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. This reduces the contact area of ​​the second transmission member 5 and the first transmission member 4, making it less likely for the first transmission member 4 and the second transmission member 5 to get stuck. However, it should be noted that the contact area between the second transmission member 5 and the first transmission member 4 cannot be too small to ensure that the function of the first transmission member 4 stably driving the second transmission member 5 and the transport unit 2 to move in the feeding direction can be smoothly realized; the first direction refers to the direction from the second transmission member 5 approaching the first transmission member 4 toward the direction from the second transmission member 5 away from the first transmission member 4.

[0059] In addition, the present invention provides a discharge position on the track 1, and the stop position and the discharge position are sequentially arranged along the feeding direction, the interval between the stop position and the discharge position is not less than the length of the transport unit 2 in the feeding direction, and the discharge position is provided with a stop unit. Through the above structure, even when the transport system switches from the feeding state to the stop state, a part of the transport unit 2 passes over the stop unit of the stop position, at this time, the movement of the transport unit 2 can still be stopped in time by starting the stop unit of the discharge position, and at this time, the material carried by the transport unit 2 output from the discharge position is recorded as the discharge amount.

[0060] And / or, the transportation system also includes a brake assembly arranged on the transportation unit 2, and the brake assembly can be specifically a brake; and / or, the transportation system also includes a detector arranged at the stop position, and the detector is used to detect the number of transportation units 2 passing through the stop position; the detector can be specifically an infrared counter, or a Hall sensor or the like, which can detect and count the number of transportation units 2 passing through the stop position. It should be noted that if the present invention adopts the discharge position mentioned in the previous paragraph, the detector is arranged at the discharge position.
