Description

TECHNICAL FIELD

[0001] The present application relates to a reinforcing bar conveying device, in particular to a chain machine for conveying reinforcing bars one by one and effectively reducing the idling rate. BACKGROUND

[0002] With the continuous development of economy and the continuous progress of society, the emergence of steel cage seam welder ends the manual binding of steel cage, improves the efficiency of China's cement product industry, whether it is pipe pile framework steel cage seam welder and square pile framework steel cage seam welder, or electric pole framework steel cage seam welder, drainage pipe framework steel cage seam welder and construction site framework steel cage seam welder.

[0003] According to the construction requirements, the main reinforcement of the steel cage is fixed by manually passing through the corresponding hole of the fixed rotating disc to the corresponding hole of the moving rotating disc, the end of the disc reinforcement (winding reinforcement) is first welded on a main reinforcement, then the fixed rotating disc and the moving rotating disc are rotated to wind the winding reinforcement on the main reinforcement (the moving disc rotates and moves backward at the same time), and welding is performed at the same time, so as to form the product steel cage - this is the working principle of the steel cage seam welder, that is, the steel cage forming machine.

[0004] Among them, before the steel cage seam welds, a reinforcing bar conveyor is used to transfer the reinforcing bars one by one between the reinforcing bar conveying mechanical hand and the external reinforcing bar station. At present, the existing reinforcing bar conveyor generally includes a rack, a main sprocket, a slave sprocket, a servo motor, a conveying chain and a plurality of blocking blocks. The main sprocket and the slave sprocket are each installed on the rack and arranged in front of and behind each other on the rack. The servo motor is installed on the rack and drives the main sprocket to rotate. The conveying chain is wound around the main sprocket and the slave sprocket, so that the conveying chain makes a rotary motion under the cooperation of the slave sprocket. All the blocking blocks are installed on the conveying chain and arranged in the rotary direction of the conveying chain at intervals. The adjacent two blocking blocks enclose a containing gap for containing reinforcing bars. Therefore, during operation, the servo motor moves the empty containing gap to the dropping position for receiving the external reinforcing bar station through the cooperation of the main sprocket and the slave sprocket, so that the reinforcing bars of the external reinforcing bar station can be sequentially dropped into the corresponding containing gap. Then the reinforcing bars are sequentially conveyed to the feeding position of the reinforcing bar conveying mechanical hand by the conveying chain, and the reinforcing bars at the feeding position are grabbed away by the reinforcing bar conveying mechanical hand and the reinforcing bar is operated.

[0005] However, since the feeding position can only receive one reinforcing bar at a time, and the conveying chain can only supplement one reinforcing bar to the feeding position after the reinforcing bar at the feeding position is grabbed away by the reinforcing bar conveying mechanical hand, the waiting time is long. Furthermore, when there is a reinforcing bar at the feeding position, the conveying chain often needs to be reversed to make the empty containing gap on the conveying chain receive the reinforcing bar dropped by the external reinforcing bar station. However, when the conveying chain receives the reinforcing bar dropped by the external reinforcing bar station, it cannot timely supplement the reinforcing bar to the feeding position where the reinforcing bar is grabbed away, so the time consumption is long and the efficiency is low.

[0023] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0024] See also Figure 1 and Figure 2 The chain conveyor 100 of the present invention is used to convey the strip-shaped steel bars 200 one by one, for example, Figure 1 The arrow A indicates the opposite direction of conveying. Of course, the conveying direction of the steel bars 200 can be other than the arrow A according to actual needs, so it is not limited thereto. The chain conveyor 100 of the present invention includes a frame 10, a chain conveying unit 20, a servo motor 30, an inclined guide surface 40 and a telescopic blocking device 50. There are five chain conveyor units 20 along the length direction of the frame 10 (i.e., the direction indicated by arrow B or the opposite direction), and two adjacent chain conveyor units 20 are arranged spaced apart so that the chain conveyor units 20 support the steel bars 200 from five locations, thereby ensuring the reliability of the chain conveyor units 20 in conveying the steel bars 200. Of course, according to actual needs, the chain conveyor units 20 can also be one, two, three, four or six, so it is not limited to this; the chain conveyor unit 20 includes a main sprocket 21, a slave sprocket 22, a conveying chain 23 and a plurality of pushing blocks 24; the main sprocket 21 and the slave sprocket 22 are respectively installed on the frame 10, and the frame 10 provides support for the main sprocket 21 and the slave sprocket 22; the main sprocket 21 and the slave sprocket 22 are arranged one after the other along the width direction of the frame 10 (i.e., the direction indicated by arrow A or the opposite direction), for example, Figure 1 In the embodiment, the main sprocket 21 is located in front of the frame 10 and the slave sprocket 22 is located at the rear of the frame 10, but is not limited thereto; the conveyor chain 23 is wound around the main sprocket 21 and the slave sprocket 22. The servo motor 30 is mounted on the frame 10 and drives the main sprocket 21 to rotate. The rotating main sprocket 21 drives the conveyor chain 23 to rotate in cooperation with the slave sprocket 22 to meet the needs of the conveyor chain 23 to rotate forward and backward. All the push blocks 24 are mounted on the conveyor chain 23 and are spaced apart along the rotation direction of the conveyor chain 23. Preferably, all the push blocks 24 are arranged along the rotation direction of the conveyor chain 23 (see Figure 3 or Figure 4the adjacent two pushing blocks 24. The inclined guide surface 40 is formed on the frame 10, extends along the width direction of the frame 10 and is arranged to be inclined upward and downward on the frame 10, and the first end 41 of the inclined guide surface 40 extends to the conveying chain 23, and the second end 42 of the inclined guide surface 40 is away from the conveying chain 23. The retractable blocking device 50 is installed on the frame 10 and extends out of the inclined guide surface 40 from a position between the first end 41 and the second end 42 of the inclined guide surface 40, as shown in Figure 4 or retracts into the inclined guide surface 40, as shown in Figure 3 More specifically, as follows:

[0025] As shown in Figure 2 to Figure 4 the inclined guide surface 40 and the retractable blocking device 50 are arranged in front of and behind each other on the frame 10, the first end 41 of the inclined guide surface 40 in front of the frame 10 extends to the front end of the conveying chain 23, and the second end 42 of the inclined guide surface 40 in front of the frame 10 is away from the conveying chain 23 in front of the frame 10 and is inclined downward, so as to ensure that the reinforcing bars 200 conveyed by the conveying chain 23 in front of the frame 10 are smoothly transferred onto the first end 41 of the inclined guide surface 40 in front of the frame 10, and then under the inclined guide action of the inclined guide surface 40 in front of the frame 10 and the self-weight of the reinforcing bars 200, the reinforcing bars 200 transferred onto the first end 41 of the inclined guide surface 40 in front of the frame 10 have a tendency to slide downward. The first end 41 of the inclined guide surface 40 behind the frame 10 extends to the rear end of the conveying chain 23, and the second end 42 of the inclined guide surface 40 behind the frame 10 is away from the conveying chain 23 behind the frame 10 and is inclined upward, so as to ensure that the reinforcing bars 200 dropped by the external reinforcing bar station onto the second end 42 of the inclined guide surface 40 behind the frame 10, and then under the inclined guide action of the inclined guide surface 40 behind the frame 10 and the self-weight of the reinforcing bars 200, the reinforcing bars 200 dropped onto the second end 42 of the inclined guide surface 40 behind the frame 10 have a tendency to slide downward, so as to facilitate the reinforcing bars 200 on the inclined guide surface 40 behind the frame 10 to drop into the receiving gap 25 on the conveying chain 23 surrounded by the adjacent two pushing blocks 24. Specifically, in Figure 2 to Figure 4In the embodiment, the chain conveyor 100 of the present invention further includes a positioning loading trough 60 formed on the frame 10, and the positioning loading trough 60 is located in front of and below the second end 42 of the inclined guide surface 40 in front of the frame 10, so that the steel bars 200 on the inclined guide surface 40 in front of the frame 10 slide into the positioning loading trough 60 under the action of their own weight; at the same time, the inclined guide surface 40 is located next to the conveyor chain 23 along the length direction of the frame 10 to ensure the reliability of the transmission docking between the first end 41 of the inclined guide surface 40 and the conveyor chain 23. Among them, in order to use the same servo motor 30 to drive all the chain conveying units 20 to work, the frame 10 is equipped with a first long rotating shaft 11 arranged along the length direction of the frame 10 and a second long rotating shaft 12 parallel to the first long rotating shaft 11 along the width direction of the frame 10. The main sprocket 21 in each chain conveying unit 20 is installed on the first long rotating shaft 11, and the slave sprocket 22 in each chain conveying unit 20 is installed on the second long rotating shaft 12. This ensures the synchronous coordination of each chain conveying unit 20 in conveying the steel bars 200, but is not limited to this. It is understandable that when there are one or more chain conveyor units 20 (i.e., more than two), each chain conveyor unit 20 corresponds to an inclined guide surface 40 and a telescopic blocking device 50. Preferably, each chain conveyor unit 20 corresponds to an inclined guide surface 40 in front of the rack 10 and an inclined guide surface 40 behind the rack 10, and also corresponds to a telescopic blocking device 50 in front of the rack 10 and a telescopic blocking device 50 behind the rack 10. See the state. Figure 1 and Figure 2 shown.

[0026] like Figure 3 and Figure 4 As shown, the telescopic blocking device 50 includes a telescopic actuator 51 and a blocking member 52 mounted on the output end of the telescopic actuator 51, thereby simplifying the structure of the telescopic blocking device 50. For example, the telescopic actuator 51 is a pneumatic or hydraulic cylinder with the output end facing upward, thereby simplifying the assembly relationship between the telescopic actuator 51 and the blocking member 52. Furthermore, the blocking member 52 may be a columnar member, a rod-shaped member, a block-shaped member, or a plate-shaped member, but is not limited thereto.

[0027] like Figure 2 to Figure 4 As shown, the chain conveyor 100 of the present invention further includes an intermediate connecting surface 70 formed on the frame 10 and extending along the width direction of the frame 10. The intermediate connecting surface 70 is connected to the inclined guide surface 40 in front of the frame 10 and the inclined guide surface 40 in the rear of the frame 10. The intermediate connecting surface 70 is also lower than the conveyor chain 23 to prevent the intermediate connecting surface 70 from interfering with the steel bars 200 conveyed by the conveyor chain 23. For example, the intermediate connecting surface 70 is a horizontal surface to more reliably prevent the intermediate connecting surface 70 from interfering with the steel bars 200 conveyed by the conveyor chain 23. In addition, the inclined guide surface 40 is a flat surface to facilitate the manufacturing and processing of the inclined guide surface 40, but the present invention is not limited to this.

[0028] Compared with the prior art, since the chain machine 100 of the present application further comprises the telescopic blocking device 50 and the inclined flow guide surface 40 formed on the rack 10, the inclined flow guide surface 40 extends along the width direction of the rack 10 and is arranged in an up-down inclined manner on the rack 10, the first end 41 of the inclined flow guide surface 40 extends to the conveying chain 23, the second end 42 of the inclined flow guide surface 40 is away from the conveying chain 23, the telescopic blocking device 50 is installed on the rack 10, and the telescopic blocking device 50 further extends out of or retracts into the inclined flow guide surface 40 from the position of the inclined flow guide surface 40 between the first end 41 and the second end 42 of the inclined flow guide surface 40; therefore, when the telescopic blocking device 50 extends out of the inclined flow guide surface 40, the reinforcing bars 200 dropped onto the inclined flow guide surface 40 from the external reinforcing bar station are blocked and temporarily stored (see Figure 4 ) and / or the reinforcing bars 200 conveyed by the conveying chain 23 and dropped onto the inclined flow guide surface 40 are blocked and temporarily stored (see Figure 4 ); even when the conveying chain 23 rotates to the feeding position or the external reinforcing bar station, the reinforcing bars 200 blocked on the inclined flow guide surface 40 can continue to be fed to the feeding position or the empty accommodating gap 25 under the action of gravity after the telescopic blocking device 50 retracts into the inclined flow guide surface 40, and therefore, the chain machine 100 of the present application has the advantages of less time consumption and high efficiency.

[0029] It should be noted that in the drawings, the direction indicated by the arrow A is the front-to-rear direction of the rack 10, the direction indicated by the arrow B is the left-to-right direction of the rack 10, and the direction indicated by the arrow C is the up-to-down direction of the rack 10.

[0030] The above only discloses preferred embodiments of the present application and cannot be used to limit the scope of the present application, and equivalent changes made according to the claims of the present application are all within the scope of the present application.
