Description

Technical Field

[0001] The utility model relates to the technical field of counters, in particular to a counter for a metal bar production line. Background Technique

[0002] Counting is the simplest basic operation. A counter is a logic circuit that implements this operation. In a digital system, a counter mainly counts the number of pulses to achieve functions such as measurement, counting, and control, and also has a frequency division function. A counter is composed of basic counting units and some control gates, and the counting unit is composed of a series of flip-flops with the function of storing information, such as RS flip-flops, T flip-flops, D flip-flops, and JK flip-flops. Counters are widely used in digital systems. For example, in the controller of an electronic computer, the instruction address is counted to sequentially fetch the next instruction, and in the arithmetic unit, the number of addition and subtraction operations is recorded during multiplication and division operations. Another example is the counting of pulses in digital instruments, etc. Counters can be used to display the working state of products. Generally speaking, they are mainly used to indicate how many copies of the folding and collating work of the product have been completed. Its main indicator lies in the number of digits of the counter, and the common ones are 3-digit and 4-digit. Obviously, the 3-digit counter can display up to 999 at most, and the 4-digit one can display up to 9999 at most. At present, the counters for metal bar production lines on the market are convenient for real-time online display and control of the number of bars during production. However, the position of the counter is generally fixed and not easy to adjust, so it is not convenient to meet the use of metal bars with different diameter specifications in production, and the versatility is poor. Moreover, during the conveying process, due to reasons such as bar crossing and overlapping, it is easy to cause interference information, interfering with the accurate identification of the detection device, thus generating counting errors.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figures 1-4As shown in the figure, a counter for a metal bar production line includes six groups of support columns 1. A transport rack 2 is arranged on the upper sides of the six groups of support columns 1. Protective nets 3 are fixedly arranged on both sides of the transport rack 2. A counting mechanism 4 is fixedly arranged on one side of the transport rack 2. A conveying mechanism 5 is arranged on the inner side and the front side of the transport rack 2. The counting mechanism 4 includes a fixed seat 41 fixedly arranged at a position close to the middle on one side of the transport rack 2. An installation box 42 is fixedly arranged on the upper side of the fixed seat 41. A round rod 43 is movably arranged inside the installation box 42. A gear 44 is fixedly sleeved on the outer side of the round rod 43. A handle 45 is fixedly arranged on the front side of the gear 44. An opening 46 is formed in the front side of the installation box 42 corresponding to the position of the handle 45. A rack 47 is movably arranged on the rear side of the gear 44. A limiting block 48 is movably arranged on the lower side of the fixed seat 41. A clamping block 49 is fixedly arranged on the upper side of the limiting block 48. A round plate 410 is fixedly arranged on the front side of the limiting block 48. An activity opening 411 is formed in the front side of the fixed seat 41 close to the lower side. A return spring 412 is fixedly connected between the installation box 42 and the round plate 410. An attachment block 413 is fixedly arranged at the upper end of the rack 47. A contact sensor 414 is fixedly installed at the lower end of the attachment block 413. A counter body 415 is fixedly installed on one side of the transport rack 2 close to the rear side of the installation box 42.

[0021] In this embodiment, inclined grooves are formed in the two sides of the installation box 42 corresponding to the position of the round rod 43. The gear 44 and the rack 47 are meshed. The handle 45 is limited and moves inside the opening 46. The limiting block 48, the clamping block 49 and the round plate 410 are an integrated mechanism. The clamping block 49 is engaged with the rack 47. The clamping block 49 is provided with inclined teeth. The round plate 410 is limited and moves inside the activity opening 411. The contact sensor 414 and the counter body 415 are electrically connected.

[0022] Specifically, first, hold the grip 45 and bend it downward, which drives the gear 44 to rotate around the round rod 43 as the center, so that the gear 44 drives the engaged rack 47 to move upward. At the same time, the rack 47 will pass over the block 49 with helical teeth. When the rack 47 needs to move further upward, pull the round rod 43 obliquely upward to the inclined slots on both sides of the installation box 42, and bend the grip 45 and the gear 44 to reset for subsequent cyclic use. When it is necessary to move the movable port 411 downward, press the round plate 410 downward to compress the return spring 412, so that the block 49 disengages from the engagement with the rack 47. At this time, move the rack 47 downward. When it moves to the appropriate position, release the round plate 410. According to the elastic action of the return spring 412, the limit block 48 and the block 49 are reset to re-engage the rack 47, so that the connecting block 413 drives the contact sensor 414 to move up and down. By contacting the transported bar with the contact sensor 414, it is convenient to contact metal bars of different specifications. The position of the contact sensor 414 can be flexibly adjusted, which is convenient to meet the use of metal bars with different diameters in production, and has strong versatility.

[0023] In this embodiment, the conveying mechanism 5 includes a motor 51 fixedly arranged at a position near one side of the front side of the transport frame 2. A plurality of groups of first synchronous pulleys 52 are movably arranged inside the transport frame 2. A first synchronous belt 53 is movably sleeved outside the plurality of groups of transport frames 2. A movable rod 54 is movably arranged at a position near the upper side inside the transport frame 2. One end of the movable rod 54 and a front-side group of the plurality of groups of first synchronous pulleys 52 are fixedly connected with second synchronous pulleys 55. A second synchronous belt 56 is movably sleeved outside the two second synchronous pulleys 55. Turntables 57 are fixedly sleeved at positions near both sides of the outside of the movable rod 54. A plurality of groups of conveying grooves 58 are arranged outside the two turntables 57. Movable grooves are arranged at positions corresponding to the two turntables 57 on the front side of the transport frame 2. The rotating shaft of the motor 51 penetrates through one side of the transport frame 2 and is fixedly connected with a front-side group of the plurality of groups of first synchronous pulleys 52.

[0024] Specifically, by starting the motor 51 to drive the plurality of groups of first synchronous pulleys 52 and the first synchronous belt 53 to rotate, and at the same time cooperating with the use of the two second synchronous pulleys 55 and the second synchronous belt 56, the movable rod 54 and the turntable 57 are driven to rotate synchronously. Then, the metal bars are transported in a limited quantity one by one through the plurality of groups of conveying grooves 58, avoiding the crossing and overlapping of the bars during the conveying process, preventing the generation of interference information, and thus reducing the counting error.

[0025] Working principle:

[0026] In use, first, hold the grip 45 and bend it downward, which drives the gear 44 to rotate around the round rod 43 as the center, so that the gear 44 drives the engaged rack 47 to move upward. At the same time, the rack 47 will pass over the block 49 with helical teeth. When the rack 47 needs to move further upward, pull the round rod 43 obliquely upward to the two side slots of the installation box 42, and bend the grip 45 and the gear 44 to reset for subsequent cyclic use. When it is necessary to move the movable port 411 downward, press the round piece 410 downward to compress the return spring 412, so that the block 49 disengages from the engagement with the rack 47. At this time, move the rack 47 downward. When it moves to the appropriate position, release the round piece 410. According to the elastic action of the return spring 412, the limit block 48 and the block 49 are reset to re-engage the rack 47, so that the connecting block 413 drives the contact sensor 414 to move up and down. By contacting the transported bar with the contact sensor 414, it is convenient to contact metal bars of different specifications. The position of the contact sensor 414 can be flexibly adjusted, so as to facilitate the use of metal bars with different diameters in production, and the versatility is strong. In addition, start the motor 51 to drive a number of first synchronous wheels 52 and first synchronous belts 53 to rotate. At the same time, cooperate with the use of two second synchronous wheels 55 and second synchronous belts 56 to drive the movable rod 54 and the turntable 57 to rotate synchronously. Then, drive the metal bars to be transported in a limited quantity and individually through a number of transport grooves 58, so as to avoid the crossing and overlapping of the bars during the transportation process, prevent the generation of interference information, and thus reduce the counting error.
