Description

A movement detecting device for an industrial conveyor having non-contact sensing}

The present invention relates to a transfer detection device for an industrial conveyor having a non-contact sensing method in which rotation by an external force of an object being transferred can be detected through a sensor in a non-contact manner by the rotation.

In general, as a method of slaughtering livestock such as cows, pigs, and chickens, a method of applying a mechanical blow such as hitting the top of the head or applying an electric shock by electrocuting a high-voltage current has been mainly used.

However, since this method of slaughter involves bloodletting while the animal is dead, bloodletting is not performed properly and unfavorable blood remains on the carcass. As a result, the meat smells fishy, the quality and taste of the meat deteriorates, and the meat is lost for a short time. There were problems such as easy discoloration and deterioration.

To solve this problem, the animal to be slaughtered is stunned, put into a state of suspended animation, then the neck or artery is cut, and then hung upside down on a shackle to bleed. A method for obtaining is disclosed.

On the other hand, after such bloodletting, many of the carcasses hung on the shackle are sequentially transported along the conveyor in a post-processing process. sensor is installed.

In this conventional sensing device, a contact bar and a contact piece are protruded on the outer surface of a rotatable roller, and the protruding bar is installed close to the conveyor to have a structure connected to an elastic body such as a coil spring, and the contact piece is a sensor through rotation of the roller. It is installed so as to have a structure in which detection is made by directly contacting with.

That is, when an external force is applied to the protruding bar in the conveying direction by the conductor being transported, the roller connected to the protruding bar rotates, and at the same time, the contact piece makes direct contact with the detection sensor to make a sensing, and the rotated protrusion is tensioned. It returns to its original state by the contraction action of the elastic body and senses the conductor in transit repeatedly.

However, such a conventional sensing device is inconvenient to perform continuous maintenance due to deterioration in the durability of the elastic body (eg shock or corrosion during contraction) and work due to physical noise generated in the process of tension/contraction. The problem of reduced efficiency is also accompanied.

In order to maintain the quality and value of livestock after death, it is necessary to remove hair from the skin of livestock in the shortest time, disassemble and process the internal organs in a sanitary manner, and through these methods, high-quality meat can be obtained.

This slaughter process is carried out in an automated machine system, and the sensor detects the carcass to enter the conveyor line, or confirms that the object has entered the line normally. Then, when the conductor moves along the conveyor line and arrives at the target position, it is separated from the conveyor by the signal transfer of the sensor device for the following process and goes to the next process. At this time, if it does not proceed in the normal way, the automatic line is stopped by sensor detection to solve the problem.

In such an automated line, the function of detecting the entry, passage, and location of an object is an important role of the sensor device, and it is important to maintain the quality of the product to prevent the automated line from being stopped unnecessarily through accurate detection. In addition, if the sensor device fails or malfunctions, the line is unnecessarily stopped, which delays processing time and adversely affects quality. Therefore, it is important that the sensor device accurately detects and does not generate errors. Due to the nature of the conveyor device, the clearance is severe and the position change occurs frequently during operation. Therefore, a sensor device that accurately detects an object and responds to the clearance of the conveyor line is required.

In order to solve the above-mentioned problems of the prior art, the present invention detects the transfer of an object in a non-contact manner to improve durability as well as prevent physical noise generated in the process of sensing to improve work efficiency. We want to provide that purpose.

In order to solve the above-described technical problem, a transfer detection device for an industrial conveyor having a non-contact sensing method according to the present invention is a bracket member equipped with a detection sensor, installed on the bracket member to rotate by the external force of an object being transferred along the conveyor After rotating in the forward direction by receiving the rotational force of the rotation bar and the rotation bar, the detection sensor and the non-contact space are maintained and sensing is performed, and the bracket member is rotatably installed so that it can be rotated in the reverse direction by its own weight and returned to the original position. It is characterized in that it comprises a sensing plate to be.

In addition, the bracket member is provided with the detection sensor, a first rotation groove rotatably coupled with the rotation bar by a rotation shaft, and a second rotation groove rotatably coupled with the detection plate. A stopper provided in the second rotational groove to limit the rotational angle of the sensing plate, wherein the first rotational groove is formed so that the rotation bar can rotate in the X-axis direction, and the second rotational groove is formed to rotate the sensing plate It is preferable that it is formed so that it can rotate in the Z-axis direction.

At this time, a diagonal chamfer is formed on one lower surface of the stopper to limit the rotation radius of the detection plate rotating in the forward direction, and the other lower surface limits the rotation radius of the detection plate to reverse rotation so that the detection plate stops in its original state. It is desirable to make it possible.

In addition, the rotation bar is rotatably coupled to the installation bracket through a shaft hole, and includes a through hole through which the lower part of the sensing plate is inserted at one side, and extends the length of the rotation bar in the direction of the conveyor at the other side of the rotation bar. It is preferable that the extended body is further provided to be detachable.

In addition, the detection plate is formed in an arc shape, but the lower part has a protruding portion inserted through the rotation bar, and the upper part has a sensor sensing outer surface of the detection sensor and facing each other after the detection plate is rotated in the forward direction. It is preferable to include cotton.

According to the present invention, when the sensing plate receiving the rotational power of the rotating bar rotates by the external force of the moving object rotates in the forward direction, the sensing surface is sensed in a non-contact manner having a non-contact space facing each other with the sensing sensor. In addition, since a separate elastic means or driving means is not intervened in the process of restoring the sensing plate to its original state after the external force of the object is extinguished, the sensor or the sensing plate can be used semi-permanently without deterioration in durability.

In addition, unlike the prior art, in the process of detecting the transfer of an object, physical noise is remarkably reduced, resulting in an effect of improving work efficiency.

Hereinafter, with reference to the accompanying drawings, a transfer detection device for an industrial conveyor having a non-contact sensing method according to the present invention (hereinafter, simply referred to as a 'transfer detection device') will be described in detail. On the other hand, the transfer detection device can be widely applied to industrial conveyor systems, but will be described below based on an embodiment applied to a slaughter system in a slaughterhouse.

Prior to the description, the detection sensor 100 in the present invention detects a change in electrical signal or light through the sensor detection surface 420 of the rotating detection plate 400, and senses that the resistance value for the change is varied. In order to clarify the gist of the present invention, the description of the structure of the detection sensor 100 will be omitted.

First, as shown in FIGS. 1 and 2, the transfer detection device 1 according to the present invention largely includes a detection sensor 100, a bracket member 200, a rotation bar 300 and a detection plate 400. And, through the organic combination of these components, when the external force of a plurality of conductors installed in the arrival hall and sequentially transported first rotates the rotation bar 300 in the direction of the 'X-axis' (refer to FIG. 1), At the same time, the detection plate 400 is rotated in the direction of the 'Z axis' (refer to FIG. 1 ), and detection is performed through the detection sensor 100 .

In addition, the detection information detected through the detection sensor 100 is transmitted to a control unit (not shown), which is not shown, and the corresponding detection information includes conductor quantity information or movement information and can be usefully used in the post-processing process. let it be

Describing the configuration of the present invention in more detail, the bracket member 200, as shown in FIGS. ) is installed close to the conveyor so that the external force of the conductor generated in the direction in which it is being transported through the conveyor is initially transmitted to the rotating bar 300, and includes an installation bracket 210 and a stopper 220 do.

For example, the installation bracket 210 may be installed on a conveyor to which a plurality of conductors (not shown) are transported or a structure in which the conveyor is installed, and a rotating bar 300 is rotatably coupled in the X-axis direction at the bottom thereof. The first rotational groove 211 and the sensing plate 400 include a second rotational groove 213 rotatably coupled in the Z-axis direction.

In addition, an installation hole for installing the detection sensor 100 is drilled on the upper part of the installation bracket 210, and the detection sensor 100 inserted into the installation hole is connected to the control means and the cable through a washer or nut. It is fixedly installed on the installation bracket 210. (See FIG. 4)

As shown, the first rotation groove 211 and the second rotation groove 213 may be formed through a pair of vertical brackets facing each other and spaced apart.

In each of the first and second rotation grooves 211 and 213, a through hole through which the rotation shaft R-S is inserted is formed so that the rotation bar 300 and the sensing plate 400 can rotate around the corresponding rotation shaft R-S. installed to have a structure

At this time, the formation position of the first rotation groove 211 is directly below the first rotation groove 211 and the through hole 320 of the rotation bar 300 installed rotatably to the second rotation groove 213. Through this, it is preferable that the protruding part 410 is stably inserted into the through hole 320 so that the rotational force of the rotating bar 300 can be transmitted to the sensing plate 400 simultaneously.

For example, as shown in the figure, the stopper 220 is fixedly installed in the second rotational groove 213 vertically formed to have a predetermined length, and its lower surface is provided to support the lower part of the sensing plate 400. (FIG. see 3)

Here, the lower surface of the stopper 220 is formed with a chamfer 221 in the form of an oblique line, and the rotation angle of the sensing plate 400 rotating in the forward direction (meaning rotation in the direction of the sensor) in the second rotation groove 213 is It is contacted so that it can be limited, and the lower surface is contacted so that it can stop at the correct position when the sensing plate 400 reversely rotates and returns to the initial position.

At this time, the inclination angle of the chamfer 221 is not limited, but the sensor sensing surface 420 formed on the upper part of the sensing plate 400 rotating in the forward direction stably approaches the sensing sensor 100 so as to have a close distance and detects It is desirable to have an inclination angle that can be achieved.

And, as shown in FIGS. 1 and 5, the rotating bar 300 rotates by the external force of the conductor being transported to transmit rotational force for rotating the sensing plate 400 to be described later, and the shaft hole 310 and a through hole 320 .

For example, the shaft hole 310 is perforated on the outer surface of the rotation bar 300, but as shown, the rotation shaft (R-S) inserted through the through hole of the first rotation groove 211 is inserted through and reciprocated in the 'X-axis' direction. installed to rotate.

For example, the through hole 320 is perforated on one side of the rotation bar 300 so that the protrusion 410 protruding from the bottom of the sensing plate 400 can be inserted, so that the sensing plate 400 ) transmits the rotational force that can rotate.

On the other hand, the rotating bar 300 that transmits rotational force to the sensing plate 400 has a rotation radius (α) of the sensing plate 400 according to the distances D1 and D2 between the shaft hole 310 and the through hole 320 described above. ) to have controllable movement distances (M/L-1, M/L-2). have a structure

That is, as shown, in the process of rotating the elongated body 330 in the direction of the '-X axis' by the external force of the conductor conveyed along the conveyor, the shaft hole 310 into which the rotating shaft R-S is inserted is penetrated as an axis The rotation bar 300 is rotated so that the moving distances M/L-1 and M/L-2 can be formed in the ball 320. ) to affect the size of the rotational radius (α) of the sensing plate 400 that has received the rotational force through ), and the sensing is performed through the sensing sensor 100 (see FIG. 8).

Thus, the rotating bar 300 rotates easily even against a strong or weak external force of the conductor being transported, and precise sensing is achieved in response to the rotation radius of the sensing plate 400 receiving the rotational force.

On the other hand, the rotation bar 300 in the present invention is elastic consisting of a column shape or a bar (BAR) shape detachably coupled to extend the length of the rotation bar 300 in order to easily receive the external force of the conductor being transferred. It may further include an extension body 330 molded of a material (eg, urethane or rubber), and the extension body 330 is fastened with a bolt or screw through a fastening hole formed on the other side of the rotation bar 300 It is used by means of fixed installation.

Furthermore, as shown in FIGS. 1, 6 and 7, the rotation bar 300 in the present invention is described as having an external force transmitted by a conductor moving from the '+X-axis' direction to the '-X-axis' direction. And although shown, this is only one embodiment, and is installed symmetrically in the first rotational groove 211 shown as needed, and is also applied to a conductor moving from the '-X axis' direction to the '+X axis' direction. possible.

In addition, the detection plate 400 is rotated in the 'Z-axis' direction by receiving the rotational force of the rotation bar 300 described above, but the projection 410 is configured to detect the detection sensor 100 by the rotation. ) and a sensor sensing surface 420.

The sensing plate 400 is formed to have an arc shape as a whole so that the center of gravity can be biased in one direction, and the rotation shaft R-S installed in the second rotation groove 213 is inserted through the lower part so that the rotation shaft R-S It is installed in a structure that can rotate around.

The sensing plate 400 extends downward from its lower end and rotates around the rotation axis R-S corresponding to the moving distance of the rotation bar 300 rotating through the protrusion 410 inserted into the through hole 320. installed to do

That is, when the rotating bar 300 rotates through the external force of the conductor being transferred and the through hole 320 moves (or rotates), the rotational force is transmitted to the protruding part 410 inserted into the through hole 320 so that the sensing plate (400) rotates in the forward direction around the rotation axis (R-S), and when the external force of the conductor is lost, it rotates in the reverse direction by its own weight and returns to its original state (see Fig. 9).

Thus, the rotation of the sensing plate 400 rotated in the forward direction is stopped by the interference of the chamfer 221 formed on the lower surface of the stopper 220, and after the stop, the sensor 100 is detected by the sensor sensing surface 420 will be executed

For example, the sensor sensing surface 420 is formed in the shape of a plate on top of the sensing plate 400 so that sensing is performed by the sensing sensor 100 by the sensing plate 400 rotating in a forward direction.

At this time, the sensor sensing surface 420 is a constant non-contact space between the outer surface of the sensor sensing surface 420 and the outer surface of the sensor 100 facing each other so that the sensing method by non-contact with the sensor 100 can be implemented ( S), it is preferable that the non-contact space part (S) have a distance within 5 to 15 mm, which is the detection method of the detection sensor 100 (for example, changes in electrical signals or light). detection, etc.), it is applicable within the range of the corresponding numerical value. (See Fig. 4)

Hereinafter, the operational relationship of the transfer detection device 1 according to the present invention will be described with reference to the accompanying drawings so that the above-described configurations can be more clearly understood.

First, referring to FIGS. 8 and 9, while a plurality of conductors are sequentially transported along a conveyor (not shown), an external force is applied to the elongated body 330 protruding in the direction of the corresponding container in the transport direction so that the first rotational groove 211 and The rotatably installed rotation bar 300 rotates in the '-X-axis' direction, and at the same time, the through-hole 320 formed in the rotation bar 300 moves in the '+X-axis' direction.

Then, the sensing plate 400 installed to have a length in the 'Z-axis' direction receives the rotational force of the rotating bar 300 through the protrusion 410 inserted into the through hole 320 and rotates in the forward direction at the same time, so that the sensing plate (400) The sensor sensing surface 420 formed on the upper part is arranged to have the sensing sensor 100 and the non-contact space portion S, and sensing is performed, and the sensing information of the sensing sensor 100 is controlled through a cable or the like. sent to Sudan.

At this time, the rotation radius of the detection plate 400 is limited through contact with the chamfer 221 formed on one side of the lower surface of the stopper 220 .

Finally, when the conductor's external force applied to the rotating bar 300 is lost by transport, the sensing plate 400 rapidly rotates in the reverse direction by its own weight, and at the same time, the rotational force of the sensing plate 400 penetrates It is transmitted to the rotation bar 300 through the protrusion 410 inserted into the ball 320, and the rotation shaft R-S rotates in the '+X-axis' direction to return to the initial state, thereby repeating the process by transferring another conductor. Sensing is achieved through action.

At this time, the sensing plate 400, which rotates in the reverse direction by its own weight, is supported on the lower side of the stopper 220 so that the reverse rotation is stopped, so that the rotation bar 300 can be positioned in the initial arrangement state. Preferably do.

As described above, in the transfer detection device 1 according to the present invention, unlike the prior art, when the sensing plate 400 receiving the rotational power of the rotating bar 300 rotating by the external force of the conductor rotates in the forward direction The sensor sensing surface 420 is detected in a non-contact manner having a non-contact space portion S facing each other with the sensing sensor 100, so that the sensor 100 or the sensing plate 400 can be detected semi-permanently without deterioration in durability. have usable effects.

In addition, unlike the prior art, in the process of detecting the transfer of the conductor, physical noise is remarkably reduced, resulting in an effect of improving work efficiency.
