Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of diamond wire saw, and particularly relates to a diamond bead high-speed counter. BACKGROUND

[0002] The diamond wire saw is widely used as a tool for cutting materials such as stone and concrete, and mainly comprises a steel wire rope and a bead arranged on the steel wire rope in intervals. The bead is composed of a steel base, a diamond fixed on the steel base and a bonding powder. The diamond wire saw is a high-value product, and the bead is a core part of the diamond wire saw and a high-value part. In the process of the diamond wire saw, the number of beads needs to be determined when the process is handed over, such as when the semi-finished beads enter and exit a transfer warehouse, and when the finished beads enter and exit a warehouse. At present, the methods for counting the beads mainly include:

[0003] ①Manual counting method: This method is low in efficiency, for example, 500,000 beads are counted in one day, about 5 persons are needed, the labor cost is high, and the method is prone to errors.

[0004] ②Weighing counting method: the weight of a batch of beads is divided by the expected weight of a single bead to estimate the number of beads in the batch. This method is not prone to errors, but the accuracy is low.

[0005] ③Template counting method: the beads are loaded into a counting template, and then the counting template loaded with the beads is transferred. This method is relatively accurate, but it consumes a lot of manpower to load the beads into the counting template, and the transfer of the beads is also very inconvenient.

[0006] As can be seen from the above, the existing technology cannot accurately and efficiently count the beads, there is a risk of theft of high-value beads, and the management of the diamond wire saw preparation process is inconvenient. CONTENT OF THE INVENTION

[0007] In view of this, in order to solve the problems raised in the background art, the present application aims to provide a diamond bead high-speed counter. The adjacent two beads have a large falling speed after a period of time, so that a large gap is formed between the adjacent two beads in a very short (a few milliseconds) time, the light transmission sensor is convenient for counting, and the counting speed and accuracy of the beads are greatly improved.

[0008] To achieve the above object, the present application provides the following technical scheme:

[0009] A diamond bead high-speed counter comprises beads to be counted, a guide pipe through which the beads pass, and a light transmission sensor matched with the outside of the guide pipe.

[0011] The light transmission sensor comprises a transmitting part and a receiving part symmetrically arranged on both sides of the straight circular tube, and the light emitted by the transmitting part can pass through the two light transmission grooves and be received by the receiving part.

[0012] Preferably, the radius of the circular arc circular tube is 10-150 mm.

[0013] Preferably, the top of the guide pipe is communicated with a guide rail arranged obliquely, and the diamond beads are guided into the guide pipe along the guide rail.

[0014] Preferably, the inclination angle a of the guide rail with the horizontal direction is less than 10°.

[0015] Preferably, an anti-skid strip is fixed inside the guide rail.

[0016] Preferably, the diamond bead high-speed counter further comprises a vibrating screener capable of automatically feeding the diamond beads to the guide rail, and the guide rail and the outer barrel of the vibrating screener are fixedly connected.

[0017] Preferably, the light transmission sensor comprises a first sensor and a second sensor arranged in sequence from top to bottom.

[0018] Preferably, the diamond bead high-speed counter further comprises a material box arranged below the straight circular tube, and the material box is used for receiving the diamond beads passing through the guide pipe.

[0019] Preferably, the diamond bead high-speed counter further comprises a base for supporting the vibrating screener and the material box, and one side of the base is fixedly provided with a guide pipe support for supporting the guide pipe, a first support for supporting the first sensor, and a second support for supporting the second sensor.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] As shown in Figure 1 , a diamond string bead high-speed counter comprises a base 1, a control box 2, a vibrating sieve 3, a guide rail 4, an anti-skid strip 5, a diamond string bead 6, a conduit 7, a conduit support 8, a first support 9, a first sensor 10, a second sensor 11, a second support 12 and a material box 13.

[0030] The control box 2 and the vibrating sieve 3 are both fixed on the base 1 by bolts; as shown in Figure 4 , the control box 2 is provided with electrical elements such as a main controller, a data storage, a wireless transmitter and a liquid crystal display screen, and the light transmission sensor is in communication connection with the main controller through the wireless transmitter.

[0031] The guide rail 4 is fixedly connected with the outer barrel of the vibrating sieve 3, and the inclination angle α of the guide rail 4 with the horizontal direction is less than 10°, and the anti-skid strip 5 is fixed inside the guide rail 4. The vibrating screening of the vibrating sieve 3 makes the diamond string bead 6 arranged into the guide rail 4 and forms uniform upward movement in the guide rail 4; the anti-skid strip 5 is made of high-temperature sintering of diamond and metal powder, or made of electroplating diamond on a metal substrate, or made of toothed hard alloy, so as to avoid the diamond string bead 6 from slipping in the guide rail 4, and thus ensure the uniform conveying of the diamond string bead 6.

[0032] The conduit 7 is fixed to one side of the base 1 through a conduit support 8, and the upper part of the conduit 7 is a 1 / 4 circular arc pipe, and the lower part of the conduit 7 is a straight circular pipe. In addition, as shown in Figure 2 the radius of the circular arc pipe is preferably 10-150 mm, and two light transmission grooves are symmetrically provided on the straight circular pipe (the inner diameter of the conduit 7 is 1-3 mm larger than the outer diameter of the diamond bead, and the smoothness of the inner wall of the circular arc pipe is less than 0.016 mm).

[0033] The first sensor 10 is fixed to one side of the base 1 through a first support 9, and the second sensor 11 is fixed to one side of the base 1 through a second support 12, and the first sensor 10 is located above the second sensor 11. Both the first sensor 10 and the second sensor 11 are U-shaped structures, and the U-shaped structures include emitting parts and receiving parts symmetrically located on both sides of the straight circular pipe, and the light emitted by the emitting part can be received by the receiving part through the two light transmission grooves. Specifically, the distance S between the position of the first sensor 10 and the top center of the conduit 7 is 0.5-1.8 m, the time T close of the sensor light scanning the bead is 0.002-0.005 s, the space L between the adjacent two beads scanned by the sensor light is 9-54 mm, the time T pass of the sensor light scanning the space between the adjacent two beads is 0.003-0.009 s, and the time T1 of counting one diamond bead is 0.005-0.014 s, or the number of diamond beads counted per second is 70-200 (the smaller the number of diamond beads counted per second, the more smooth the diamond beads pass through the arc pipe, and the more accurate the counting, and in actual production, about 50 diamond beads per second can meet the requirements).

[0034] The material box 13 is supported and placed on the base 1 and used to contain the diamond beads 6 passing through the conduit 7.

[0035] In summary, when counting the diamond beads 6:

[0036] (1) The diamond beads 6 to be counted are poured into the outer barrel of the vibrating sieve 3, and the ascending speed of the diamond beads 6 along the guide rail 4 is controlled by adjusting the vibration frequency of the vibrating sieve 3.

[0037] (2) The diamond beads 6 make free fall motion through the conduit 7, and specifically in combination with Figure 3 , the bead E starts to make free fall motion downward at the initial position (at this time, the falling speed of the bead E is zero). As shown in A; the distance from the light transmission sensor position (light switch position) is S (unit: m), and the time is T S (unit: s). As shown in B; the distance of the light transmission sensor light scanning the bead E is a (unit: mm), at this time, the light is blocked by the bead E, and the light blocking time is T 闭(unit: s); as shown in Figure C: L (unit: mm) is the distance of the gap between the two adjacent beads E and F scanned by the light of the light pass sensor, at this time the light is unobstructed, and the light unobstructed time is T 通 (unit: s); as shown in Figures C and D: T pass can be controlled by adjusting the frequency of the vibrator in the vibration disc; T1 = T 闭 + T 通 is the time for counting one bead (unit: s). Specifically:

[0038] S = g * T S 2 / 2;

[0039] S + a = g * (T S + T 闭 ) 2 / 2;

[0040] T S - L = T S - T 通 ;

[0041] L = S - g * (T S-L ) 2 / 2;

[0042] In the above formula: g is the acceleration of gravity, g = 10 m / s 2 ; T S-L is the time for the bead 2 to move downward by a free fall distance (S - L) from the initial position, unit: s; a is the length of the bead base, for simplicity of calculation, a = 14 mm.

[0043] Based on the above formula, the relationship between the counting time T1 of one bead, the distance L of the light pass sensor scanning the gap between the two adjacent beads E and F, and the distance S of the bead moving downward by a free fall distance to the position of the light switch is obtained as shown in Table 1

[0047] (3) If the two first sensors 10 are located at the difference of the number of beads sensed by the second sensor 11 is within 0.1%, the counter counts effectively, and the maximum value is taken as the number of diamond beads;
