[0035] The specific embodiments of the utility model are described in detail below in combination with the drawings.It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0036] The embodiment of the utility model provides a kind of parallel conveying system, as shown in Figures 1 to 3 Auxiliary material pickup port 211 is provided on the top surface of auxiliary material carrier 21, and the top end of main material carrier 11 is provided with main material limiting port 1121, which faces auxiliary line conveying device 2 and allows the end 32 of main material 3 to extend to auxiliary line conveying device 2, and main material limiting port 1121 has a guide section 1122 that gradually decreases in opening along the direction away from the top surface of main material carrier 11.

[0037] The parallel conveying system provided by the embodiment of the utility model, as shown in Figure 1 Auxiliary line conveying device 2 configured to be parallel to main line conveying device 1, such as main line conveying device 1 is longitudinally arranged, and auxiliary line conveying device 2 is also longitudinally arranged, which can effectively reduce the space occupied by the conveying system in the transverse direction.

[0038] In addition, since auxiliary material pickup port 211 and main material limiting port 1121 are oppositely arranged, and the end of main material 3 can enter main material limiting port 1121 from guide section 1122 and extend to auxiliary line conveying device 2 from main material limiting port 1121, it is convenient to limit main material 3, and during the process of installing auxiliary material 6 to the end of main material 3, auxiliary material 6 does not need to be transferred to the other side of main line conveying device 1, which facilitates the butt joint of auxiliary material 6 and main material 3, and the system structure is more compact.

[0039] In an optional embodiment, as shown in Figure 1 First interval 4 is configured to accommodate auxiliary material assembly equipment 5.

[0040] The first interval 4 provides installation and operation space for the auxiliary material assembling device 5, which facilitates the auxiliary material assembling device 5 to glue the auxiliary material 6 on the end 32 of the main material 3 and to pick up the auxiliary material 6 on the auxiliary material carrier 21 and glue the auxiliary material 6 on the end 32 of the main material 3.

[0041] As shown in Figure 1 , the auxiliary material assembling device 5 can be arranged in an up-down manner with part of the auxiliary line conveying device 2, and the two together occupy the space in the horizontal direction, so that the system structure is more compact.

[0042] In an optional embodiment, as shown in Figure 1 , the auxiliary line conveying device 2 has a feeding end 22 and a discharging end 23 along the conveying direction of the auxiliary line conveying device 2, and the feeding end 22 and the discharging end 23 are both horizontally opposite to the side of the main line conveying device 1.

[0043] In the above embodiment, since the feeding end 22 and the discharging end 23 are both horizontally opposite to the side of the main line conveying device 1, that is, the feeding end 22 and the discharging end 23 do not protrude from the main line conveying device 1 in the longitudinal direction, the space occupied by the system in the longitudinal direction is basically equal to the space occupied by the main line conveying device 1 in the longitudinal direction, and the system is more compact. In addition, compared with the up-down arrangement of the main line conveying device 1 and the auxiliary line conveying device 2, the main line conveying device 1 and the auxiliary line conveying device 2 can be directly placed on the ground, and the operation is more stable.

[0044] In an optional embodiment, as shown in Figure 4 , the auxiliary line conveying device 2 further comprises a first transmission mechanism 24, the conveying direction of the first transmission mechanism 24 is parallel to the main line conveying device 1, and the auxiliary material carrier 21 is connected with the first transmission mechanism 24.

[0045] In the above embodiment, the first transmission mechanism 24 can drive the auxiliary material carrier 21 to move in the conveying direction parallel to the main line conveying device 1, so that the auxiliary material pickup port 211 of the auxiliary material carrier 21 can always be aligned with the main material limiting port 1121 of the main material carrier 11.

[0046] The first transmission mechanism 24 can adopt a chain transmission mechanism or a belt transmission mechanism.

[0047] In a preferred embodiment, the first transmission mechanism 24 adopts a belt transmission mechanism, as shown in Figure 4 , specifically including a rack 241, a power source 242, a driving wheel, a belt 243 and a driven wheel, the power source 242 is installed on the rack 241, the driving wheel and the driven wheel are rotationally connected with the rack 241, and the belt 243 is connected between the driving wheel and the driven wheel.

[0048] In use, the power source 242 can drive the driving wheel to rotate, and the driven wheel can be driven to rotate by the belt 243. The auxiliary material carrier 21 can be fixed on the belt 243 and move with the belt 243.

[0049] The power source 242 can be a rotary motor or a combination of a rotary motor and a transmission assembly. The transmission assembly can transmit the power of the motor to the driving wheel. The transmission assembly can be in the form of a belt transmission, a gear transmission or a chain transmission.

[0050] In an optional embodiment, as shown in Figure 2 The auxiliary material carrier 21 is provided with at least one carrying cavity. The side of the carrying cavity away from the first transmission mechanism 24 is provided with an inlet and outlet port 212 communicating with the auxiliary material pickup port 211. The carrying cavity is recessed from the inlet and outlet port 212 to the first transmission mechanism 24 and is provided with a first mounting groove 213 and a second mounting groove 214 respectively carrying two ends of the auxiliary material 6. The first mounting groove 213 and the second mounting groove 214 are oppositely arranged along the direction facing the main line conveying device 1. The side of the second mounting groove 214 away from the first mounting groove 213 is provided with the auxiliary material pickup port 211.

[0051] In use, the end of the auxiliary material 6 not required to be connected with the end head 32 of the main material 3 can be placed in the first mounting groove 213, and the end of the auxiliary material 6 required to be connected with the end head 32 can be placed in the second mounting groove 214. The auxiliary material assembly equipment 5 can be inserted into the auxiliary material 6 from the auxiliary material pickup port 211, then lift the auxiliary material 6 upward, so that the auxiliary material 6 is taken out from the inlet and outlet port 212, then grab the auxiliary material 6 and align the auxiliary material 6 with the end head 32 to realize the connection with the end head 32.

[0052] In the above auxiliary material carrier 21, the auxiliary material 6 can be taken out from the top inlet and outlet port 212. The end face of the auxiliary material 6 in the axial direction does not hinder the taking out of the auxiliary material 6. After the auxiliary material 6 is taken out, the auxiliary material 6 does not need to be reversed. The end of the auxiliary material 6 not required to be connected with the end head 32 can be grabbed and aligned with the oppositely arranged end head 32, which is convenient for the butt joint of the auxiliary material 6 and the main material 3.

[0053] Specifically, the auxiliary material carrier 21 can be provided with one carrying cavity, or two, three, four or more carrying cavities.

[0054] When the auxiliary material carrier 21 is provided with multiple carrying cavities, the multiple carrying cavities are distributed along the conveying direction of the auxiliary line conveying device 2.

[0055] The above embodiment has the advantage that when each carrying cavity carries the auxiliary material 6, the auxiliary material assembly equipment 5 only needs to change the material taking position along the conveying direction of the auxiliary line conveying device 2 to take out each auxiliary material, which is convenient for the operation of the auxiliary material assembly equipment 5.

[0056] In a preferred embodiment, as shown in Figure 2 The auxiliary material carrier 21 is provided with two bearing cavities.

[0057] The two bearing cavities can be of the same size or different sizes. When the two bearing cavities are of different sizes, the two bearing cavities can carry different auxiliary materials 6, so that the applicability of the carrier is stronger.

[0058] In an alternative embodiment, as shown in Figure 2 The first mounting groove 213 is closed on the side away from the second mounting groove 214 to define the axial position of the auxiliary material 6.

[0059] In the above embodiment, since the first mounting groove 213 is closed on the side away from the second mounting groove 214, when the auxiliary material assembly device 5 is inserted into the auxiliary material 6 from the auxiliary material pickup port 211, the side closed by the first mounting groove 213 can avoid the auxiliary material 6 from moving axially, so that the auxiliary material assembly device 5 can be stably inserted into the auxiliary material 6, thereby taking out the auxiliary material 6 from the access port 212 during upward movement.

[0060] In an alternative embodiment, as shown in Figure 3 The main material carrier 11 includes a support seat 111 and a mounting member 112, the mounting member 112 is connected to one side of the support seat 111 and forms a mounting cavity accommodating the winding part 31 of the main material 3 with the support seat 111, and the mounting member 112 has a main material limiting port 1121 limiting the position of the end head 32.

[0061] In use, the main material 3 can be placed in the mounting cavity after being wound, so that the space occupied by the product is smaller, which is conducive to improving the compactness of the main line conveying device 1. In addition, the end head 32 of the main material 3 can be limited in the main material limiting port 1121 and extend towards the auxiliary line conveying device 2, which is convenient for installing the auxiliary material 6 on the two end heads 32 of the main material 3 on one side of the main material 3.

[0062] The main line conveying device 1 further includes a second transmission mechanism, the conveying direction of the second transmission mechanism is parallel to the conveying direction of the first transmission mechanism, and the main material carrier 11 can be connected with the second transmission mechanism.

[0063] The alternative structure of the second transmission mechanism is similar to that of the first transmission mechanism, and therefore, in order to save space, the structure of the second transmission mechanism will not be described in detail.

[0064] It should be additionally noted that in the above embodiments, the improvement of the parallel conveying system is not in the auxiliary material assembly device 5 itself, and the leading out of the auxiliary material assembly device 5 is only for the purpose of explaining the significance of the first interval 4. The above auxiliary material assembly device 5 can directly use the existing device, and therefore its structure will not be described in detail.

[0065] In an optional embodiment, as shown in Figure 5 The parallel conveying system further comprises a feeding device 7 configured to feed the auxiliary line conveying device 2.

[0066] In the above embodiment, the feeding device 7 can feed the auxiliary line conveying device 2, so as to ensure that the auxiliary material 6 can be continuously transported from the auxiliary line conveying device 2 to the next work station.

[0067] In an optional embodiment, as shown in Figure 5 The feeding device 7 comprises a material bin 71, a conveying mechanism 72 located between the discharging end 23 of the material bin 71 and the feeding end 22 of the auxiliary line conveying device 2, and a mechanical arm 73 configured to place the auxiliary material 6 on the conveying mechanism 72 on the auxiliary material carrier 21.

[0068] In use, the material bin 71 conveys the auxiliary material 6 to the conveying mechanism 72, and in the process of conveying the auxiliary material 6 on the conveying mechanism 72, the mechanical arm 73 picks up the auxiliary material 6 and places it on the auxiliary material carrier 21.

[0069] Since the conveying mechanism 72 only serves to carry the auxiliary material 6 and wait for the mechanical arm 73 to pick up, the conveying mechanism 72 does not need to be designed to be long in the transverse direction.

[0070] The above feeding device 7 can stably feed the auxiliary material 6, does not need manual operation, saves manpower, and can ensure the feeding efficiency.

[0071] In an optional embodiment, the feeding device 7 can further comprise a camera to capture the position of the auxiliary material 6 on the conveying mechanism 72, so as to facilitate the mechanical arm 73 to grasp and place on the auxiliary line conveying device 2.

[0072] It should be additionally noted that in the above embodiments, the improvement of the parallel conveying system does not lie in the material bin 71, the conveying mechanism 72 and the mechanical arm 73, which are introduced only to illustrate that they do not need to occupy a large size in the transverse direction, and the material bin 71, the conveying mechanism 72 and the mechanical arm 73 can directly use existing devices, so the structure will not be described in detail.

[0073] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
