Description

TECHNICAL FIELD

[0001] The utility model relates to a flow line, in particular to a carrier drive device on a flow line. BACKGROUND

[0002] The flow line is used for preparing products with multiple processing procedures, and when the preparation is carried out, the product components are carried and transported by the carrier, and the carrier carries the components to move forward on the flow line, so that each procedure of the product is completed in turn. According to the different properties of the product components, the required carrier structure is generally different. For example, some components of shoe products are relatively small and scattered, and have high hardness, and are not suitable for being transported by clamping. For the carrying of these components, a wheel type tray type carrier can be used. The structure of the flow line includes a closed loop main rail, a plurality of workstations are arranged on the outer side of the main rail, and one or more processing positions are formed at the workstations, so that the corresponding procedures of the product are completed. The main structure of the workstation includes an annular support rail, and the carrier is supported to walk or run on the support rail. A flexible belt drive mechanism is arranged on the lower side of the main rail and the support rail, the drive mechanism has a plurality of push blocks protruding therefrom, a force receiving rod protruding downward is arranged on the carrier, and the push blocks push the carrier to walk forward on the support rail or the main rail by abutting against the lower end of the force receiving rod. Since the number of carriers on the flow line is generally large, when the carrier is transferred from the main rail to the support rail of the workstation, the speed of the rear carrier is relatively slow, so that the rear carrier loses power and waits in place to prevent the rear carrier from tipping over the front carrier. In another case, due to the complexity of the process of some stations and the slow production speed, it is possible that a large number of waiting carriers are accumulated in some areas of the flow line, and these accumulated carriers cannot be continuously pushed by the push blocks to prevent damage to the force receiving rod or the drive mechanism.

[0003] The rear carrier can lose power through the interaction between adjacent carriers, so it is necessary to design a structure suitable for interaction to adapt to the above problems occurring in the production process. SUMMARY

[0004] The utility model needs to solve the technical problem: provide a kind of flow line carrier drive device, the drive device can be well adapted to the accumulation situation generated in the running process of carrier, and the accumulated rear carrier loses power.

[0005] To solve the technical problem, the utility model discloses a technical scheme of a flow line carrier driving device, which comprises a flexible driving belt, a plurality of push blocks are protrusively arranged on the driving belt, the carrier comprises a walking frame, a force receiving rod is hingedly connected to the walking frame, the lower end of the force receiving rod extends laterally towards the lower side of the walking frame, the push block is driven by the driving belt to abut against the lower end of the force receiving rod to make the carrier walk forward, and the lower end of the force receiving rod extends obliquely towards the lower rear of the carrier.

[0006] The driving belt is generally a driving chain and can also be a common transmission belt, and the push block is protrusively arranged towards the upper side of the driving belt. When the carriers are stacked, the tail structure on the front carrier pushes and presses the force receiving rod to deflect, and if the force applying surface on the push block is in a vertical state, the force applying surface will hinder the lower end of the force receiving rod to lift in an arc track, and the timely disengagement between the force receiving rod and the push block cannot be ensured.

[0007] Further, the inclination angle of the force applying surface is between 60-80 degrees. On the basis of ensuring that the push block stably applies force to the force receiving rod, the force receiving rod and the push block can also be well adapted to disengage.

[0008] Further, the lower end of the force receiving rod forms a force receiving part, the length of the force receiving part is greater than the thickness of the force receiving rod, and the force receiving rod is connected to the middle position of the length direction of the force receiving part. This improves the stability of force application and force receiving between the force receiving rod and the push block, and facilitates the push block to provide continuous and stable thrust to the force receiving rod.

[0009] Further, a through hole is arranged in the force receiving part, and the inner side surface of the through hole is similar in shape to the outer peripheral surface of the force receiving part. On the basis of ensuring that the push block stably applies force to the force receiving rod, the weight of the lower end of the force receiving rod can also be effectively reduced, and the force receiving rod can be deflected on the basis of external force application.

[0010] Further, the part of the force receiving part in contact with the force applying surface is a convex arc surface. The force receiving part and the force applying surface are in linear contact, thereby facilitating the timely and smooth disengagement between the force receiving part and the force applying surface.

[0011] Further, the push block is in the shape of "convex", and the force applying surface is arranged on the big end of the push block. This push block can ensure stable connection with the driving belt, effectively reduce the weight of the push block, and reduce the load of the driving belt.

[0012] Further, a notch is arranged on the upper surface of the big end of the push block, the notch opens towards the small end of the push block, and a through coupling hole is arranged on the bottom of the notch and the small end of the push block. This further reduces the weight of the push block and facilitates the processing of the coupling hole.

[0013] Further, a protruding mounting portion is arranged on the bottom surface of the push block, the width of the mounting portion is less than the width of the small end of the push block, and the coupling hole penetrates the mounting portion. The push block is adapted to the case where the driving belt is a chain, so that the connection between the push block and the driving belt is firm.

[0014] Compared with the prior art, the utility model has the beneficial effects that the force receiving rod is hinged on the walking frame, can well adapt to the action relationship requirement between the push block and the force receiving rod, the force receiving rod is convenient for receiving external force and changing the state, and can well meet the actual working requirement. The force receiving surface is arranged in the inclined state, the lower end of the force receiving rod can be separated from the force receiving surface when the carrier needs to lose power, the force receiving surface well adapts to the demand of the hinged force receiving rod for the movement space, and the lower end of the force receiving rod can be separated from the push block in time and in order.

DETAILED DESCRIPTION

[0022] In combination with the drawings, the flow line carrier driving device is used for driving the carrier in the flow line to move forward. The structure of the flow line comprises a closed loop main rail, a plurality of curved branch rails are arranged on the outer side of the main rail, a plurality of flexible driving belts 1 are arranged at positions corresponding to the main rail and the branch rail, and a plurality of push blocks 6 are protrudingly arranged on the driving belts 1.

[0023] The structure of the carrier includes a walking frame 4, on which a walking wheel 3 is arranged, and the outer periphery of the walking wheel 3 is rollably supported on the main rail and the branch rail. A tray is arranged on the walking frame 4, and the tray is used for carrying the components of the product. A force receiving rod 7 is arranged on the walking frame 4, and the force receiving rod 7 is pivotally connected to the walking frame 4. The lower end of the force receiving rod 7 extends to the lower side of the walking frame 4, and a pushing block 6 is driven by the driving belt 1 to abut against the lower end of the force receiving rod 7, so that the carrier walks forward on the main rail and the branch rail. The lower end of the force receiving rod 7 extends to the lower rear side of the carrier, and a force applying surface 61 is formed on the front end of the pushing block 6. When the pushing block 6 pushes the carrier to walk forward, the force applying surface 61 abuts against the lower end of the force receiving rod 7. The force applying surface 61 is an inclined surface, and the upper end of the force applying surface 61 inclines to the rear side. The extending direction of the lower end of the force receiving rod 7 should ensure that the force applying surface 61 pushes the carrier to walk forward through the force receiving rod 7. Generally, when the force is transmitted, the lower end of the force receiving rod 7 is substantially perpendicular to the force applying surface 61. Generally, the angle of the force applying surface 61 is between 60-80 degrees.

[0024] A rear connecting seat 5 is fixedly connected to the rear end of the walking frame 4, and a tail rod 2 extending to the rear side is connected to the rear connecting seat 5. Figure 1 Fig. 4 shows that the rear carrier moves relative to the front carrier in the arrow direction to the front side. As the rear carrier gradually moves to the front carrier, the tail rod 2 on the front carrier pushes and presses the upper end of the force receiving rod 7 on the rear carrier, so that Figure 2 When the tail rod 2 and the force receiving rod 7 are combined together, the lower end of the force receiving rod 7 on the rear carrier is separated from the force applying surface 61 on the pushing block 6.

[0025] The lower end of the force receiving rod 7 forms a force receiving part 71 to increase the abutting size between the force receiving rod 7 and the force applying surface 61. The length of the force receiving part 71 is greater than the thickness of the force receiving rod 7, the force receiving rod 7 is connected to the middle position of the length direction of the force receiving part 71, and the force receiving part 71 is integrated with the force receiving rod 7. The force receiving part 71 is a block-shaped body, and a through hole 72 is arranged in the force receiving part 71. The inner side of the through hole 72 and the outer periphery of the force receiving part 71 are similar in shape. The part of the force receiving part 71 in contact with the force applying surface 61 is a convex curved surface, and the convex curved surface is in linear contact with the force applying surface 61, which is beneficial to the separation or force application between the force receiving part 71 and the force applying surface 61.

[0026] Referring to Figure 5 , 6The pushing block 6 is in the shape of a "nub", and the force applying surface 61 is arranged on the big end of the pushing block 6. A recess 63 is arranged on the upper surface of the big end of the pushing block 6, the recess 63 is open towards the small end of the pushing block 6, the bottom surface of the recess 63 is flush with the upper surface of the small end of the pushing block 6, and a through coupling hole 64 is arranged on the bottom of the recess 63 and the small end of the pushing block 6. A protruding mounting portion 62 is arranged on the bottom surface of the pushing block 6, the width of the mounting portion 62 is smaller than the width of the small end of the pushing block 6, and the coupling hole 64 penetrates the mounting portion 62.
