Description

Technical Field

[0001] The present invention relates to the field of cargo conveyor technology, and specifically to modular conveyor belts.

Background Art

[0002] Modular belts are widely used in the field of cargo conveyors and are usually used to transport individual products or workpieces in a production environment. These modular belt units are generally manufactured by injection molding with plastic materials. The modular belt units are continuously arranged in a direction perpendicular to the conveying direction, are positioned with adjacent modules in the conveying direction, and are rotatably connected via pin shafts.

[0003] Regarding the mesh belt conveyor used in an automobile manufacturing factory, it may be necessary to simultaneously drive 30 to 40 automobiles or vehicle bodies to be assembled, and about 2 to 3 workers per work station, and continuously operate at a speed of about 3 to 8 meters per minute. Among them, as a typical example, the completion line of an automobile assembly factory with a tact time of 60 JPH has a work station length of 6 meters and an operating speed of 6 meters per minute. Workers complete the injection of liquids such as fuel, brake fluid, and coolant on the mesh belt conveyor and complete the preliminary inspection and adjustment of vehicle body assembly. The modular-mesh belt constitutes the upper surface of the mesh belt conveyor, drives the automobiles / vehicle bodies that are relatively stationary with respect to the mesh belt and the workers walking on the mesh belt to operate toward the drive end. The modular-mesh belt generally has a high molecular weight polyethylene plate or a stainless steel plate disposed as a support plate below, and relative slippage occurs between the modular-mesh belt and the support plate during operation.

[0004] Conventional gasoline or electric vehicles produced in automobile manufacturing plants may weigh more than 2,000 KG per vehicle. However, in recent years, for plug-in hybrid vehicles and range extender vehicles that are booming in sales in China, due to the simultaneous installation of large batteries and fuel engines / transmissions in the vehicles, the weight of a single vehicle may reach more than 3,000 KG / vehicle. When the modular mesh belt operates towards the driving end, in order to effectively reduce the frictional resistance generated between it and the support plate and the tensile force applied to the corresponding mesh belt, thereby reducing the energy consumption of the drive mechanism, the modular mesh belt needs to have a low sliding friction coefficient with the support plate arranged below it. Conversely, the automobile or vehicle body needs to maintain relative static with the modular mesh belt. In order for walking operators to complete corresponding assembly, inspection, adjustment and other operations, the modular mesh belt needs to have a large static friction coefficient between the automobile tire (rubber material) and the chassis for fixing the vehicle body (usually angle steel pipe), and a large sliding friction coefficient with the soles of the walking operators' safety shoes, and it is determined that it needs to reach a non-slip level of R10 or more known to the workers.

[0005] In the prior art, the materials used for the mesh belt modular units manufactured by injection molding process with a single plastic material are usually POM, PA, PP base materials, which cannot achieve the required low friction coefficient with the support plate, and cannot achieve the required high friction coefficient for utilization between the vehicle tire / vehicle body mounted directly in contact and the chassis for mounting the vehicle body. Due to this, the use of maintenance-free and low-noise mesh belt conveyors in automobile production plants is greatly restricted. In specific operating situations, automobile production plants are forced to use old-fashioned steel chain conveyors that are noisy, require frequent refueling and maintenance, and require deep foundations and pits.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The object of the present invention is to achieve a necessary low coefficient of friction between a support plate by contacting it through a longitudinal connecting member for friction reduction, and at the same time, to achieve a necessary high coefficient of friction for use between a mounting cradle for mounting an automobile tire / vehicle body that is mounted and in direct contact, by providing a tensile modular conveyor belt of the longitudinal connecting member type for friction reduction.

Means for Solving the Problems

[0007] In order to solve the above technical problems, the technical solution adopted in the present invention is as follows.

[0008] A tensile modular conveyor belt of the longitudinal connecting member type for friction reduction, including a plurality of modular belt unit bodies that are hinge-connected to adjacent modular belt unit bodies. At both front and rear ends of the modular belt unit body, a front row of lugs and a rear row of lugs are respectively provided. A front pin shaft and a rear pin shaft are respectively inserted through the front row of lugs and the rear row of lugs. A through groove is provided on the lower surface of the modular belt unit. A longitudinal connecting member for friction reduction is provided in the through groove. The longitudinal connecting member for friction reduction is inserted through the front pin shaft and the rear pin shaft. The bottom surface of the longitudinal connecting member for friction reduction protrudes from the lower surface of the modular belt unit body so that the longitudinal connecting member for friction reduction directly contacts the lower support plate and the modular belt unit body does not contact the lower support plate.

[0009] Furthermore, the top surface of the longitudinal connecting member for friction reduction is lower than the upper surface of the modular belt unit body so that the longitudinal connecting member for friction reduction does not contact the workpiece being conveyed.

[0010] Furthermore, a reinforcing bar is provided on the lower surface of the modular belt unit body.

[0011] Furthermore, anti-slip protrusions are distributed on the upper surface of the modular belt unit body.

[0012] Furthermore, the modular belt unit body is manufactured by injection molding engineering plastics.

[0013] Furthermore, the engineering plastics are POM material, PA material or PP material.

[0014] Furthermore, the longitudinal connecting member for friction reduction is made of a friction reduction material with a low friction coefficient and excellent wear resistance.

[0015] Furthermore, the friction reduction material is metal, alloy, polymer material or carbon fiber material.

[0016] Furthermore, the longitudinal connecting member for friction reduction includes connecting piece A and connecting piece B with a bent non-flat plate structure. The corresponding front holes and corresponding rear holes of connecting piece A and connecting piece B are respectively inserted into the front pin shaft and the rear pin shaft. One end of connecting piece A and one end of connecting piece B are in close contact with each other, and the other ends of connecting piece A and connecting piece B expand outward.

[0017] Furthermore, a locking member is provided between connecting piece A and connecting piece B. At the lower end of the locking member, an insertion joint for inserting into the locking port of the modular belt unit body is provided. At the upper end of the locking member, a locking joint is provided. The locking joint is locked to the upper sides of connecting piece A and connecting piece B so as to lock connecting piece A and connecting piece B to the modular belt unit body.

Advantages of the Invention

[0018] The beneficial effects of the present invention are as follows. This application can reduce the sliding friction resistance during the operation of the conveyor by the direct contact between the longitudinal connecting member for friction reduction and the support plate, thereby reducing the energy consumption of the conveyor. When manufacturing the longitudinal connecting member using a high-strength friction-reducing material, the tensile strength of the conveyor belt can also be significantly increased. This application can reliably stop the automobile / vehicle body on the surface of the conveyor belt on the conveyor by increasing the roughness of the upper surface of the modular belt unit body, facilitating production assembly, inspection, and adjustment, and improving the anti-slip level for the operator of the mesh belt to R10 or above.

[0019] This application further reduces the product cost by manufacturing the main part of the modular mesh belt using an engineering plastic with a high friction coefficient and low cost.

Therefore, it cannot be understood as limiting the present invention.

[0023] As shown in FIGS. 1, 2, 3, 4, 5, and 6, there is provided a tensile modular conveyor belt of a longitudinal connecting member type for reducing friction, including a plurality of modular belt unit bodies 1 in which adjacent modular belt unit bodies are hinged to each other. At both front and rear ends of the modular belt unit body 1, a front row of lugs 2 and a rear row of lugs 3 are provided. A front pin shaft 4 and a rear pin shaft 5 are respectively inserted through the front row of lugs 2 and the rear row of lugs 3. A through groove 6 is provided on the lower surface of the modular belt unit body 1. A longitudinal connecting member 7 for reducing friction is provided in the through groove 6. The longitudinal connecting member 7 for reducing friction includes a connecting piece A12 and a connecting piece B13. The connecting piece A12 and the connecting piece B13 have a bent non-flat plate structure. Corresponding front holes 8 and corresponding rear holes 9 of the connecting piece A12 and the connecting piece B13 are inserted through the front pin shaft 4 and the rear pin shaft 5. One end of the connecting piece A12 and one end of the connecting piece B13 are in close contact with each other. The other end of the connecting piece A12 and the other end of the connecting piece B13 expand outward. A locking member 14 is provided between the connecting piece A12 and the connecting piece B13. At the lower end of the locking member 14, an insertion joint 15 for inserting into a locking port 16 of the modular belt unit body 1 is provided. At the upper end of the locking member 14, a locking joint 17 is provided. The locking joint 17 is fixed to the upper side edges of the connecting piece A12 and the connecting piece B13 so as to lock the connecting piece A12 and the connecting piece B13 to the modular belt unit body 1.

[0024] The bottom surface of the longitudinal connecting member 7 for reducing friction protrudes from the lower surface of the modular belt unit body 1 such that the longitudinal connecting member 7 for reducing friction directly contacts the lower support plate and the modular belt unit body 1 does not contact the lower support plate. The top surface of the longitudinal connecting member 7 for reducing friction is lower than the upper surface of the modular belt unit body 1 so that the longitudinal connecting member for reducing friction does not contact the workpiece being conveyed.

[0025] A reinforcing bar 10 is provided on the lower surface of the modular belt unit body 1. The reinforcing bar 10, the front row of lugs 2, the rear row of lugs 3, and the modular belt unit body 1 are integrally formed.

[0026] On the upper surface of the modular belt unit body 1, anti-slip protrusions 11 are distributed.

[0027] The modular belt unit body 1 is manufactured by injection molding engineering plastics. The engineering plastics are POM material, PA material or PP material.

[0028] The longitudinal connecting member 7 for friction reduction is made of a friction reduction material with a low friction coefficient and excellent wear resistance. The friction reduction material is metal, alloy, polymer material or carbon fiber material.

[0029] Working principle: In this application, a longitudinal connecting member for friction reduction is added to the modular belt unit body. When the longitudinal connecting member for friction reduction directly contacts the lower support plate and the modular belt unit body does not contact the lower support plate, the bottom surface of the longitudinal connecting member for friction reduction protrudes from the lower surface of the modular belt unit body. That is, by attaching a longitudinal connecting member for friction reduction with a low friction coefficient and excellent wear resistance to the front and rear pin shafts of the modular belt unit body, the longitudinal connecting member for friction reduction directly contacts the lower support plate to achieve the required low-sliding friction coefficient. Also, when manufacturing the longitudinal connecting member using a high-strength friction reduction material, the longitudinal connecting member can greatly increase the tensile strength of the modular-mesh belt. An engineering plastic with a high friction coefficient is used for the modular belt unit body part. Generally, this engineering plastic is cheaper than an engineering plastic with a low friction coefficient, and a large static friction coefficient or sliding friction coefficient is formed between the automobile tire / vehicle body sag above the conveyor belt and the operator.
