Description

TECHNICAL FIELD

[0001] The utility model relates to aerated block production technical field, concretely relates to a steel bar quantity detection device. BACKGROUND

[0002] After the aerated concrete embryo is preformed into a rectangle, it needs to be cut and peeled by side cutting to form a regular cuboid, and then the cuboid is cut into multiple small cuboids by transverse cutting and longitudinal cutting. When cutting, the embryo is placed on a transfer rack, and the embryo is transported to different process stages through the circulation of the rack. Before cutting the embryo, in order to avoid the cutting steel wire from being placed on the surface of the rack during the online cutting process, a plurality of steel bars need to be laid on the surface of the rack, and the steel bars have a certain interval to ensure that the steel wire can pass through the interval during cutting. However, the number of steel bars cannot be too small, and the top surface of the steel bar needs to be dispersed to the maximum extent below the embryo to support the embryo and prevent the embryo from deforming or being damaged during cutting. At the same time, the steel bars should be evenly and smoothly laid to ensure uniform stress during cutting.

[0003] At present, most enterprises adopt manual method, which needs manual judgment of the number of steel bars, but has the following shortcomings: since the steel bar is about 3cm wide and 1cm thick, and one side of the steel bar is in contact with the bottom surface of the embryo, the distribution is dense, and two pieces of area need to be laid on a single rack, about 80-90 steel bars are arranged in each area. After the steel bars are laid, the counting time is long when the number of steel bars is manually checked, and the workers need to concentrate on counting, otherwise it is easy to confuse. After counting, the arrangement between the steel bars also needs to be adjusted, for example, a worker holds a steel rod and knocks the protruding steel bar to make the top surface of the steel bar flush with other steel bars to ensure smooth laying. When knocking, the force needs to be controlled by experienced workers, otherwise the steel bar may be bent or the knocking position may be inaccurate. Therefore, our company proposes a steel bar quantity detection device to solve the above problems. UTILITY MODEL CONTENTS

[0004] The utility model provides a steel bar quantity detection device to solve the problem that workers need to manually count and adjust the arrangement of the steel bars laid on the rack in the existing aerated block cutting process, which leads to high labor intensity of workers.

[0005] The utility model discloses a steel bar quantity detection device, including frame, the transmission roll that sets up along the length interval of frame, a plurality of steel bars parallel to the length of frame, the steel bar is along the length interval of transmission roll and sets up, is provided with counting unit below the both ends of frame respectively, and counting unit includes support, horizontal displacement mechanism, counting sensor, sliding block, and the support is installed in the both sides of frame respectively, and horizontal displacement mechanism is fixed on the support and is parallel to the both opposite ends of frame, and the height of horizontal displacement mechanism is lower than transmission roll, and sliding block is installed on horizontal displacement mechanism, and sensor is installed on sliding block, and sensor is perpendicular to the bottom surface of steel bar, and counting sensor, horizontal displacement mechanism all electricity connects the controller of external device, and the controller is used to obtain the quantity of steel bar.

[0006] The basic principle of the scheme is that the horizontal displacement mechanism drives the sliding block to reciprocate below the both ends of the frame, and in the sliding process, the sliding block will pass through the end of each steel bar in turn. Since the frame adopts the structure of the transmission roll, the transmission roll is located in the middle of the frame, and there is no obstruction below the end of the steel bar. When the sliding block passes through the end of the steel bar, the counting sensor on the sliding block can identify and read the number of steel bars. Finally, when the sliding block moves from one end to the other end, the controller displays the total number of steel bars on the display, and the worker increases or decreases the steel bars according to the number of steel bars.

[0007] The beneficial effects of the scheme are that the existing aerated block needs to lay a whole steel bar between the bottom surface of the blank and the transmission roll before cutting. The steel bar is about 3cm wide and 1cm thick, and one side of the steel bar thickness contacts the bottom surface of the blank. The steel bars are distributed densely and staggered. Two pieces of steel bars need to be laid on each area on a single frame, and about 80-90 steel bars are arranged in each area. After the steel bars are laid, it takes a long time to count the number of steel bars manually, and the worker needs to concentrate on counting, otherwise it is easy to confuse. The scheme drives the sensor to move by setting the reciprocating sliding block of the horizontal displacement mechanism. The sensor only needs to move from one end to the other end to obtain the total number of the whole steel bar. The mechanical structure is simple, the operation is convenient, the problem of high labor intensity caused by manual counting is reduced, and the efficiency of steel bar laying in the production process of the aerated block is improved.

[0008] Further, a shaft is installed on the support, one end of the shaft is connected with a driving motor, the driving motor is used for driving the axial horizontal rotation of the shaft, a pressing strip is connected with the other end of the shaft, the rotation range of the pressing strip is from perpendicular to the ground to parallel to the ground, the driving motor is electrically connected with the controller, and the controller is used for controlling the start and stop of the driving motor. By starting the rotation of the pressing strip at different positions, the pressing strip is attached to the steel bar, and the top surface of the steel bar is aligned by the pressing strip, avoiding the problem of labor intensity caused by the worker holding the steel rod to knock the steel bar to deform the steel bar.

[0009] Further, the supports are symmetrically installed on the two sides of the rack respectively, and the length of the pressing strip is 1 / 2 of the conveying roller.

[0010] Further, the supports are symmetrically installed on the two sides of the rack respectively, and the length of the pressing strip is 1 / 2 of the conveying roller.

[0011] Further, the controller is used for starting the rotation of the pressing strips at the two ends first, and then starting the rotation of the pressing strips in the middle part.

[0012] Further, the sensor is an infrared sensor, and the emitter of the infrared sensor faces upward. BRIEF DESCRIPTION OF DRAWINGS

[0017] The embodiment is basically as shown in the accompanying drawings Figure 1 to Figure 2 :

[0018] A steel strip quantity detection device, comprising a rack 1, the rack 1 is installed on the horizontal ground of a factory building, conveying rollers 2 are installed along the length of the rack 1 at intervals, the conveying rollers 2 are used for horizontally conveying aerated blocks 4, a plurality of steel strips 3 are dispersed between the conveying rollers and the bottom surfaces of the aerated blocks 4, the steel strips 3 are of a specification of 3cm in width, 1cm in thickness and 2m in length, 80-90 steel strips 3 are distributed along the length direction of the conveying rollers, and the specific number of the steel strips 3 is determined according to the quality of aerated blocks 4 of different molds on site.

[0019] The support 8 is installed at both ends of the rack 1, and the support 8 is installed at four vertices of the rack. The horizontal displacement mechanism 5 is arranged in parallel along the length of the support 8. In the embodiment, the height of the horizontal displacement mechanism 5 is lower than the height of the conveying roller, and the horizontal displacement mechanism 5 adopts a linear guide rail. The slider 6 reciprocates on the linear guide rail. The sensor 7 is installed on the slider 6. The sensor 7 is perpendicular to the bottom surface of the steel strip 3. The sensor 7 can move vertically to the length of the steel strip 3 under the drive of the slider 6. The sensor 7 is an infrared sensor 7. The sensor 7 is used for counting and identifying the steel strip 3 below the steel strip 3. The sensor 7 and the horizontal displacement mechanism 5 are electrically connected to the controller.

[0020] The rotating shaft 9 is installed on the support 8 and located at the rear side of the horizontal displacement mechanism 5. The end of the rotating shaft 9 is key-connected to the driving motor. The driving motor is electrically connected to the controller. The other end of the rotating shaft 9 is key-connected to the pressing strip 10. The rotating range of the pressing strip 10 is 90°. The pressing strip 10 can rotate from the state perpendicular to the ground to the state parallel to the ground. When the pressing strip 10 is parallel to the ground, the pressing strip 10 is perpendicular to the steel strip 3, and the bottom surface of the pressing strip 10 is in contact with the top surface of the steel strip 3. Through the rotation of the pressing strip 10, part of the protruding steel strip 3 can be pressed downward on the conveying roller 2, and the upper surfaces of the pressing strips 10 are kept flush.

[0021] In the embodiment, in order to reduce the height of the single pressing strip 10, the pressing strips 10 on both sides of the rack are symmetrically arranged. The length of the single pressing strip 10 is half of the conveying roller 2.

[0022] The specific implementation process is as follows:

[0023] When the steel strips 3 are placed on the rack by workers, the workers start the horizontal displacement mechanism 5 through the controller. The horizontal displacement mechanism 5 drives the slider 6 to move below the end of the region of the two steel strips 3. The infrared sensor 7 on the slider 6 passes the steel strip 3 in sequence. The controller obtains the counting condition of the steel strip 3 through the infrared sensor 7. When the slider 6 moves from one end of the horizontal displacement mechanism 5 to the other end, the number of the steel strips 3 in the region of the whole steel strip 3 is obtained. The controller displays the number on the display. The workers increase or decrease the steel strips 3 according to the number on the display. Then, the driving motor is started to drive the pressing strip 10 to rotate. The pressing strip 10 presses the top surface of the steel strip 3 downward. Finally, the pressing strip 10 is horizontal to the ground and perpendicular to all the steel strips 3. After all the steel strips 3 are pressed, the top surfaces are kept flush. The arrangement of the steel strips 3 is completed. The next process of placing the air-entraining block 4 blank on the steel strip 3 can be performed.

[0024] Embodiment 2:

[0025] The embodiment is different from the embodiment 1 in that the steel strip 3 in the embodiment covers the whole rack 1 in length, and the air entraining block 4 with a large billet length is lifted and connected as a whole, instead of arranging the steel strip 3 in two regions in the embodiment 1. The pressing strip 10 is asymmetrically arranged, and the pressing strip 10 in the embodiment is staggered, and the adjacent pressing strips 10 are arranged on different sides of the transmission roller, and the four pressing strips 10 are distributed at intervals on the whole rack length, and the length of each pressing strip 10 is 2 / 3 of the whole transmission roller 2. The controller is used to control the driving motor to drive the pressing strip 10 to rotate. The staggered pressing strip 10 ensures that the force on the whole length of the steel strip 3 is uniform.

[0026] The specific implementation process is as follows:

[0027] After the sensor 7 completes the counting of the number of steel strips 3, the controller starts the driving motor, first starts the driving motor at both ends, rotates the pressing strips 10 at the two farthest ends and different sides, and then starts the driving motor at the middle, rotates the pressing strips 10 at the middle two different sides downward, and touches the middle part of the steel strip 3 to flatten the middle part of the steel strip 3. The subsequent mechanical body is placed on the steel strip 3, and the cutting process can be started. The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme known in the art are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
