TECHNICAL FIELD
[0001] The utility model relates to a flow line, especially a stabilizing device capable of keeping the rear carrier stable when the carriers are stacked on the flow line. BACKGROUND
[0002] The flow line is used for preparing products with multiple processing procedures. When the products are prepared, the product components are carried and delivered by carriers, and the carriers with the components move forward on the flow line, thereby sequentially completing each procedure of the products. According to different properties of the product components, the required carrier structures are generally different. For example, some components of footwear products are relatively small and scattered, and have relatively large hardness, and are not suitable for being delivered by clamping. For the carrying of these components, a wheeled pallet carrier can be used. The flow line includes a closed-loop main rail. A main drive belt adapted to the direction of the main rail is arranged on the lower side of the main rail. A plurality of push blocks are protrudingly arranged on the main drive belt. A force receiving rod protruding downward is arranged on the carrier. The carrier moves on the main rail by the pushing of the push blocks on the force receiving rod. A plurality of workstations including branch rails are arranged on the outer side of the flow line. When the carrier on the main rail is switched to the branch rail, the moving speed of the carrier is relatively slow. If there are relatively many carriers on the main rail, the rear carrier will directly collide with the front carrier when the front carrier is switched. In order to avoid the rear carrier from being pushed by the push blocks when it collides with the front carrier, a tail rod is arranged at the rear end of the carrier. The tail rod on the front carrier is used to abut against the force receiving rod on the rear carrier, so that the lower end of the force receiving rod on the rear carrier is separated from the push blocks, so that the rear carrier loses power. However, because the carriers move relatively smoothly on the main rail or the branch rail, and the carriers generally collide with each other, the front carrier is easy to generate a large reverse impact force on the rear carrier, so that the rear carrier rebounds backward. After the rear carrier rebounds, the force receiving rod on the rear carrier is easy to abut against the push blocks and be forced, so that the rear carrier moves back and forth on the rail with a small amplitude. The force receiving rod on the rear carrier is easy to abut against the push blocks repeatedly, which can damage the force receiving rod. SUMMARY
[0003] The utility model needs to solve the technical problem: provide a kind of flow line carrier stacking stabilizing device, to reduce the impact force generated between carriers when they are stacked and collide on the rail, improve the use stability of flow line.
[0004] To solve the technical problem, the utility model discloses a technical scheme of a pipeline carrier stacking stabilizing device, the carrier includes a walking frame, walking wheels are rotatably arranged on the walking frame, a force receiving rod is hingedly arranged at the front end of the walking frame, a tail rod is arranged at the rear end of the walking frame, the lower end of the force receiving rod extends downward from the walking frame, the lower end of the force receiving rod is used for receiving the pushing force of a pushing block of a driving mechanism in the pipeline, and the walking frame is used for moving forward under the pushing of the pushing force; the tail rod is used for interacting with the force receiving rod on the rear carrier when the carrier is stacked, so that the lower end of the force receiving rod is lifted to the upper side of the pushing block to be separated from the pushing block, characterized in that an interaction structure is arranged between the two adjacent walking frames, and the interaction structure is used for reducing the impact force generated when the rear carrier collides with the front carrier, so that the tail rod on the front carrier is separated from the force receiving rod on the rear carrier.
[0005] The interaction structure can be as follows: the impact force is reduced by the interaction between the front end of the force receiving rod and the tail rod, and the rear carrier is not easy to directly collide with the front carrier. Alternatively, the impact force can be reduced by arranging magnets or elastic bodies that cooperate with each other between the corresponding positions of the two adjacent carriers.
[0006] Further, the interaction structure is arranged between the tail rod and the force receiving rod. No additional corresponding structure needs to be arranged between the two carriers, and only the existing structure is used to realize the corresponding function, so that the structure is simple and convenient to arrange.
[0007] Further, the upper end of the force receiving rod extends obliquely upward from the front of the walking frame, and the upper end of the force receiving rod is used for interacting with the lower surface of the tail rod to reduce the impact force. The upper end of the force receiving rod interacts with the tail rod, and under the action of the lower end of the force receiving rod, the sliding friction between the two is used to reduce the impact force, and finally the upper end of the force receiving rod is attached to the lower end of the tail rod, so that the rear carrier is kept stable.
[0008] Further, the tail rod is curved and has a flat portion and a guide portion that are connected as a whole, and the guide portion is located at the rear end of the tail rod and extends obliquely upward from the rear of the walking frame. This facilitates the action of the tail rod on the upper end of the force receiving rod, and the action of the tail rod on the force receiving rod is stable.
[0009] Further, the bottom surface of the flat portion is provided with a concave-convex structure. This can effectively increase the roughness of the bottom surface of the flat portion and facilitate effective blocking of the upper end of the force receiving rod.
[0010] Further, the concave-convex structure is formed by a plurality of convex strips arranged on the flat part in the left-right direction, the outer circumferential surface of the convex strip is a convex arc surface, and the upper end surface of the force receiving rod is a convex arc surface. The arrangement of the convex strips is well adapted to the advancing direction of the force receiving rod, and is conducive to the sliding of the upper end of the force receiving rod on the flat part while satisfying the blocking of the force receiving rod.
[0011] Further, the upper end surface of the force receiving rod protrudes upward, and the cross section of the upper end surface is the same as that of the outer circumferential surface of the convex strip. The upper end of the force receiving rod is generally not stuck between the convex strips, thereby effectively ensuring the stability of the action between the tail rod and the upper end of the force receiving rod.
[0012] Further, the rear end of the walking frame is fixed with a rear connecting seat, a mounting port in the shape of a horn is arranged on the rear connecting seat, the mounting port is large at the rear end and small at the front end, and the tail rod is hingedly connected to the bottom of the mounting port. Through the arrangement of the mounting port, the tail rod can swing on the walking frame within a certain range, and can well adapt to the track changing action of the carrier.
[0013] Compared with the prior art, the utility model has the beneficial effects that: by arranging the action structure between the two adjacent carriers, the impact force generated when the rear carrier collides with the front carrier is reduced, so that the front carrier does not generate a large recoil force on the rear carrier, the rear carrier is not easy to rebound backward and separate from the front carrier, and thus after the front carrier stays on the track, the rear carrier can be arranged and stayed stably in turn, which well adapts to the situation of track changing of the carrier or the situation of waiting for buffering of the carrier on the track.

[0019] The pipeline carrier stacking stabilizer is arranged between two adjacent carriers to prevent the rear carrier from rebounding backward due to a large impact force after the two carriers collide.
[0020] The carrier includes a walking frame 4, a walking wheel 3 rotatably arranged on the walking frame 4, the walking frame 4 used for supporting a tray, and the walking wheel 3 used for being placed on a support rail or a main rail. A force receiving rod is hingedly arranged at a front end of the walking frame 4, and a tail rod 52 is arranged at a rear end of the walking frame 4. A lower end 52 of the force receiving rod extends downwardly toward the walking frame 4, and an outer end of the tail rod 52 extends outwardly. A driving mechanism is arranged at a lower side of the carrier, and the driving mechanism includes a driving belt 6, which can be a chain or a common transmission belt. A plurality of push blocks 1 are protrusively arranged on the driving belt 6, and the lower end 52 of the force receiving rod is used for receiving a pushing force of the push blocks 1, and the walking frame 4 is used for moving forwardly under the pushing force. As shown in Figure 1 When the carriers are stacked on the track, for example, the front carrier is changed to a work station, or the carriers are too many on the track, and the carriers need to be stopped and buffered on the track, the rear carrier has a relative speed difference with the front carrier, and the rear carrier moves close to the front carrier in the arrow direction in Figure 1 The tail rod 52 on the front carrier finally acts on the force receiving rod on the rear carrier, and the lower end 52 of the force receiving rod is lifted to the upper side of the push block 1 to be separated from the push block 1. Figure 2 As shown in Figure 2 , the lower end 52 of the force receiving rod on the rear carrier is lifted to the position of the double-dot-dashed line in , and is completely separated from the push block 1. In the embodiment, the tail rod 52 mainly acts on the upper end 51 of the force receiving rod, and of course, the tail rod 52 can also act on the side of the lower end 52 of the force receiving rod.
[0021] In order to avoid or reduce the rebound times of the rear carrier when the rear carrier collides with the front carrier, an acting structure is arranged between the two walking frames 4, and the acting structure is used for reducing the impact force generated when the rear carrier collides with the front carrier, so that the tail rod 52 on the front carrier is separated from the force receiving rod on the rear carrier. The collision refers to a working collision generated when the carrier moves on the pipeline at a normal speed, and does not include a collision generated by an artificial or other external force.
[0022] The acting structure is combined with Figure 1 , 2, 3, the action structure is arranged between the tail rod 52 and the force rod, the upper end 51 of the force rod is obliquely extended to the front upper side of the walking frame 4, and the middle position of the force rod is hingedly connected to the front end of the walking frame 4 of the carrier. The upper end 51 of the force rod is used for acting on the lower surface of the tail rod 52, so that the impact force is reduced.

The guide portion 22 is located at the rear end side of the tail rod 52 and obliquely extends to the rear upper side of the walking frame. When the rear carrier moves towards the front carrier, the front end of the force rod of the rear carrier first abuts against the guide portion 22. Under the action of the guide portion 22, the upper end 51 of the force rod is pressed to the bottom surface position of the flat portion 23. At this time, the lower end 52 of the force rod is completely separated from the push block 1 and will not receive the pushing force of the push block 1.
[0024] A concave-convex structure is arranged on the bottom surface of the flat portion 23. The concave-convex structure can be a plurality of convex bodies arranged in point form. As shown in the figure, the concave-convex structure is formed by a plurality of convex strips 21. The convex strips 21 are arranged on the flat portion 23 in the left-right direction and are arranged in parallel in the length direction of the flat portion 23. The outer circumferential surface of the convex strip 21 is a convex arc surface, and the upper end 51 of the force rod is also a convex arc surface. Figure 1 , 2 As shown in FIG. 5, the upper end 51 of the force rod protrudes towards the upper side, and the cross sections of the upper end 51 and the outer circumferential surface of the convex strip 21 are the same.
