In this embodiment, the bottom surface of the horizontal section of the distribution frame 6 is tangent to the bars, and the horizontal section of the distribution frame is used for pushing the bars stacked on the two bars to the space between the two empty limit bars 11.

In this embodiment, the counting device 3 includes a fixed frame 31 and a rotating plate 32, the fixed frame 31 is fixedly connected with the distribution frame 6, a rotating shaft 33 is fixedly connected to the middle of the rotating plate 32, the rotating shaft 33 is rotatably connected to the fixed frame 31, a connecting portion 34 is respectively disposed on the upper portion of the rotating plate 32 and the inner wall of the fixed frame 31, the two connecting portions 34 are connected by a tension spring 35, a metal patch 36 is fixedly connected to the bottom of the rotating plate 32, the metal patch 36 is in contact with a rod, the metal patch 36 is connected to the input end of the background computer through a wire, when the two metal patches 36 are in contact with the rod at the same time, the energization loops of the two metal patches 36 are turned on, the background computer obtains an electrical signal input, which is marked as 1, the rod is far away from the metal patch 36 to obtain an electrical signal input disconnection, which is marked as 0, when passing through one of the two metal patches 1 and 0, it indicates that one steel bar 7 completely passes through the counting, and one is added.

In this embodiment, the first conveying line 1 is provided with a plurality of limiting strips 11, and only one bar can be accommodated between adjacent limiting strips 11. The detection error when the two bars are close to and the metal patch 36 is contacted with the bars is avoided.

In this embodiment, the separating device 4 includes a separating frame 41, a frame 42, a supporting member 43 and a hydraulic cylinder 44, wherein one end of the separating frame 41 is fixedly connected with a transmission shaft 45, the transmission shaft 45 is rotatably connected with the frame 42, the top of the supporting member 43 is rotatably connected with a supporting wheel 46, and the bottom of the supporting member is hinged with the frame 42, the output shaft of the hydraulic cylinder 44 is hinged with the supporting member 43, and the bottom of the hydraulic cylinder is hinged with the frame 42.

In this embodiment, the blocking device 5 includes a gear 51, a rack 52 and a chute frame 53, the chute frame 53 is fixedly connected to the frame 42, the gear 51 is fixedly connected to the transmission shaft 45, the rack 52 is slidably connected to the chute frame 53 and engaged with the gear 51, and a blocking plate 54 is fixedly connected to the rack 52.

In this embodiment, the upper surface of the spacer 41 is lower than the second transport line 2 when it is horizontal. To ensure that the spacer 41 is not lifted, the reinforcement bars 7 can be transported on the second conveyor line 2 to the stop plate 54.

The working process and the principle thereof are as follows:

after production reinforcing bar 7 fall on first transfer chain 1 to fall into between the spacing 11, first transfer chain 1 drives reinforcing bar 7 and puts up 6 movements to the branch, if have the reinforcing bar 7 of piling together after bumping branch and putting up 6 then blockked by branch and put up 6, and distribute this reinforcing bar 7 that is blockked between two spacing 11 empty, ensure not have the problem that reinforcing bar 7 piled up.

Then the steel bar 7 contacts with the two metal patches 36 at the bottom of the two rotating plates 32, the steel bar 7 is against the metal patches 36, so that the rotating plates 32 deflect by taking the rotating shaft 33 as a rotating center, and the tension spring 35 is lengthened, so that the metal patches 36 can always keep a contact state with the steel bar 7.

At the moment, the circuit is switched on, the background computer obtains an electric signal input, the electric signal is recorded as 1 in the binary code, then when the steel bar 7 continues to move along with the first conveying belt until the steel bar 7 is separated from the metal patch 36, the electric signal is switched off, the background computer records the switching-off signal as 0, the situation that one steel bar 7 completely passes through is shown, and the counting is increased by one. The tension spring 35 drives the rotating plate 32 to reset for subsequent detection and counting.

When the counting is not up to the preset standard, the hydraulic cylinder 44 keeps in a shortened state, the separation frame 41 keeps in a horizontal state, the upper surface of the separation frame is lower than the second conveying line 2, the steel bars 7 pass through the counting device 3 and then fall onto the second conveying line 2, and the like, all the subsequent steel bars 7 pass through the metal patches 36 for counting, and because the hydraulic cylinder 44 keeps in a shortened state all the time when the number is not up to the standard, the separation frame 41 keeps in a horizontal state, the rack 52 is in a high position, and the stop plate 54 is higher than the second conveying line 2, so that the steel bars 7 on the second conveying line 2 are gathered at the stop plate 54.

When the number of the steel bars 7 on the first conveying line 1 and the steel bars 7 on the right side of the stop plate 54 on the second conveying line 2 are lifted, the steel bars 7 slide down to the left, and finally the steel bars 7 are gathered together.

When the separation frame 41 is lifted, the transmission shaft 45 rotates to drive the gear 51 to rotate anticlockwise, the rack 52 moves downwards, and when the blocking plate 54 moves downwards to a position where the reinforcing steel bars 7 are not blocked, the reinforcing steel bars 7 can be smoothly conveyed away from the second conveying line 2, so that the quantity of the reinforcing steel bars 7 conveyed in a pile at each time is preset. When the bars 7 are transported away, the hydraulic cylinders 44 are retracted and reset, the spacer 41 and the stop plate 54 are also reset, and the second conveyor line 2 continues to convey and re-counts the number of subsequent bars 7. The reinforcing bars 7 of the next stack are blocked by the blocking plate 54 and are not mixed into the reinforcing bars 7 of the previous stack, so that the number of the reinforcing bars 7 in each stack is ensured to be the same.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
