Description

Technical Field

[0001] The utility model relates to the field of mechanical transmission, in particular to a conveyor line. Background Art

[0002] The tunnel furnace is a tunnel-type mechanical equipment that bakes products through heat conduction, convection, and radiation. The tunnel furnace body is generally very long, and the baking chamber is a long and narrow tunnel with a continuously running conveyor line in the tunnel. The product is placed on the tooling, and the tooling generates relative movement between the conveyor chain plate, steel belt or mesh belt and the electric heating element or direct-burning combustion rod, thereby completing the work of uniform baking and conveying. Ordinary transmission belts, conveyor chains and other conveyor lines do not have a positioning function for the product, and the conveyor line of the tunnel furnace is relatively long, and the tooling on the conveyor line is seriously out of position, resulting in the robot arm being unable to accurately pick up the tooling or product, affecting the tooling and product conveyor lines. Therefore, this problem needs to be solved. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a conveyor line, which mainly solves the problem of displacement of tooling on the conveyor line.

[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0005] A conveyor line comprises a conveyor chain assembly, an auxiliary wheel assembly and a guide component mounted on a bracket;

[0006] The transmission chain assembly includes a driving sprocket, a driven sprocket, a chain and a motor. The chain is wound around the driving sprocket and the driven sprocket. The motor drives the driving sprocket to rotate. A plurality of positioning blocks are installed on the chain at equal intervals. The transmission chain assembly is equipped with a plurality of push blocks. The push blocks are detachably plugged into the positioning blocks. The plurality of push blocks are distributed at equal intervals along the chain.

[0008] The guide component comprises two guide bars parallel to the conveying chain assembly, two rows of rollers are located between the two guide bars, and the top surface of the guide bar is higher than the top of the roller.

[0009] Furthermore, proximity switches for detecting push blocks are installed at both ends of the conveyor chain assembly, and a photoelectric sensor is installed at at least one end of the conveyor chain assembly; the conveyor line also includes a control system, and the proximity switch, photoelectric sensor, and motor are all electrically or signal-connected to the control system.

[0010] Furthermore, a groove is provided on the top surface of the positioning block, and a positioning column which is plugged and matched with the groove is provided on the bottom of the push block.

[0011] Furthermore, the positioning block and the pushing block are both in the shape of long strips, and the length direction of the two is perpendicular to the chain transmission direction. The tops of both sides of the pushing block in the width direction are provided with chamfers to facilitate the placement of tooling or products between the two pushing blocks.

[0012] The utility model has the following beneficial effects:

[0013] 1. The tooling is placed between two push blocks, and two guide bars are used to limit the two sides of the tooling. The guide bars and push blocks restrict the tooling around to prevent the tooling from moving on the conveyor line.

[0014] 2. Proximity switches for detecting push blocks are installed at both ends of the conveyor chain assembly. When the conveyor line is in operation, if the proximity switch signal is not detected within the set time, the control system will issue a material jam alarm.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] like Figure 1 As shown, this embodiment discloses a conveyor line, including a conveyor chain assembly 1, an auxiliary wheel assembly 2 and a guide component installed on a bracket;

[0020] The transmission chain assembly 1 includes a driving sprocket, a driven sprocket, a chain and a motor 3. The chain is wound around the driving sprocket and the driven sprocket. The motor 3 drives the driving sprocket to rotate. A plurality of positioning blocks 4 are installed at equal intervals on the chain. The transmission chain assembly 1 is equipped with a plurality of push blocks 5. The push blocks 5 are detachably plugged into the positioning blocks 4. The plurality of push blocks 5 are distributed at equal intervals along the chain.

[0021] Proximity switches 6 for detecting the push block 5 are installed at both ends of the conveyor chain assembly 1;

[0022] At least one end of the conveyor chain assembly 1 is equipped with a photoelectric sensor 7 for detecting whether there is a product on the tooling on the conveyor chain. In this embodiment, both ends of the conveyor chain assembly 1 are equipped with photoelectric sensors 7;

[0023] The auxiliary wheel assembly 2 includes two rows of rollers parallel to the conveyor chain assembly 1, and the conveyor chain assembly 1 is located between the two rows of rollers; in other embodiments, two rows of balls may be used instead of the two rows of rollers;

[0024] The guide component includes two guide bars 8 parallel to the conveyor chain assembly 1, two rows of rollers are located between the two guide bars 8, and the top surface of the guide bar 8 is higher than the top of the roller.

[0025] It also includes a control system (usually a PLC control system), and the proximity switch 6, the photoelectric sensor 7, and the motor 3 are all electrically connected or signal-connected to the control system. Preferably, the conveyor line can be equipped with an alarm, such as a buzzer or a three-color light, and the control system is connected to the alarm.

[0026] The positioning block 4 and the push block 5 are plug-connected. Specifically, a groove 9 is provided on the top surface of the positioning block 4, and a positioning column that plugs and matches the groove 9 on the positioning block 4 is provided at the bottom of the push block 5. In other embodiments, a groove 9 can also be provided at the bottom of the push block 5, and a positioning column can be provided on the top surface of the positioning block 4. Preferably, the positioning block 4 and the push block 5 are both in the shape of long strips, and the length direction of both is perpendicular to the chain transmission direction. The top surface of the positioning block 4 is provided with at least two grooves 9 along the length direction, and correspondingly, at least two positioning columns are provided at the bottom of the push block 5. The long strip-shaped push block 5 is conducive to increasing the contact surface between the push block 5 and the tooling to avoid displacement of the tooling. Chamfers 10 are provided on the top of both sides of the push block 5 in the width direction, which is conducive to placing the tooling between the two push blocks 5. The two push blocks 5 and the two guide strips 8 limit the tooling in four directions of front, back, left, and right to avoid displacement of the tooling during transportation.

[0027] The movement principle of the conveyor line is: the motor 3 drives the chain to move, and the tooling is placed between the push blocks 5 installed at equal distances on the chain. When the chain moves, the push blocks 5 push the tooling to slide forward on the two rows of rollers. Since the push blocks 5 and the positioning blocks 4 are detachable, the conveyor line can transport tooling of different sizes by adjusting the distance between the push blocks 5.

[0028] Positioning principle: Proximity switches 6 are installed at both ends of the chain, which can sense the push blocks 5 installed at equal distances on the chain. When the proximity switches 6 sense the push blocks 5, they transmit signals to the control system, and the controller system controls the motor 3 to stop running, so as to achieve the purpose of positioning the push blocks 5 on the chain.

[0029] Alarm principle: When the conveyor line is in operation, the control system will issue a material jam alarm if it fails to detect a signal from the proximity switch 6 within the set time; when the conveyor line is used as a tooling return line, when the photoelectric sensor 7 continuously senses the product, a material jam alarm or a material retrieval failure alarm will be issued.

[0030] As described above, the embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model. Therefore, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the protection scope of the utility model.
