Description

Technical Field

[0001] The utility model relates to the field of milk bag transportation, in particular to a push-type transmission control device and a transmission device. Background Art

[0002] The packaging section of bottled milk bags uses a platform-type transmission chain buffer platform. When a certain device behind fails or stops due to other factors, the filling will continue to fill the milk bags and transport them to the buffer platform. A laser electric eye is installed at the end of the transmission platform. When the milk bags on the platform are full and trigger the electric eye sensing area, the transmission chain will stop, and then the shutdown signal will be transmitted to the filling machine. However, the milk bags squeeze each other, which will cause the product to be squeezed and deformed, bringing quality risks. In order to prevent the milk bags from squeezing each other and the filling machine from being blocked due to quantity competition, an operator needs to be arranged to keep an eye on the milk bags in front of the buffer platform and use a walkie-talkie to notify the filler to operate the equipment.

[0003] In addition, the working condition of the electric eye trigger is that the sensing area is full of milk bags, blocking the direct laser. In production, it is often the case that milk bags slowly enter or stop in the electric eye sensing area, causing the filling machine to stop abnormally. Utility Model Content

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0036] like Figures 1 to 9 As shown, the present application provides a push-type transmission control device, comprising:

[0037] The support frame 1 is used to be installed on the outside of the transmission device. The support frame 1 has a first side and a second side along a conveying direction V perpendicular to the transmission device, and the first side faces the transmission device (the second side faces away from the transmission device); two through holes 121 arranged opposite to each other are opened at the first end of the support frame 1 along the vertical direction, and the axes of the through holes 121 are parallel to the conveying direction V, and one of the through holes 121 is used to install an electric eye sensor;

[0038] A thrust rod 2 is located outside the second side of the support frame 1, a first end of the thrust rod 2 is connected to the second end of the support frame 1, and the second end of the thrust rod 2 can move between the two sides of the support frame 1 perpendicular to the conveying direction V; a blocking plate 21 is also provided on the thrust rod 2, and the blocking plate 21 can be located between the two through holes 121 when the second end of the thrust rod 2 extends out of the first side of the support frame 1 and extends into the conveying area of ​​the transmission device;

[0039] The trigger rod 3 includes an entrance oblique rod section 31 and a sliding straight rod section 32. The entrance oblique rod section 31 can extend obliquely from the second side to the first side along the conveying direction V to be connected to the first end of the sliding straight rod section 32; the second end of the thrust rod 2 is connected to the sliding straight rod section 32, and the length direction of the sliding straight rod section 32 is parallel to the conveying direction V. The trigger rod 3 can push the second end of the thrust rod 2 to move to the blocking plate 21 away from the through hole 121 when subjected to a preset thrust.

[0040] It can be understood that the conveying direction V of the transmission device extends in the horizontal direction. When in use, the control device is fixed to the outer surface of the transmission device through the support frame 1. The axes of the two through holes 121 are arranged horizontally and the two are arranged opposite each other. The laser emitting end of the electric eye sensor faces the other through hole 121, and the laser directly emitted by the electric eye sensor can pass through the other through hole 121. The entire control device has two working states. When in the first working state, the second end of the thrust rod 2 extends out of the first side of the support frame 1 and extends into the conveying area of ​​the transmission device. At this time, the trigger rod 3 is also located in the conveying area of ​​the transmission device. The blocking plate 21 is located between the two through holes 121 to block the laser directly emitted by the electric eye sensor, and the transmission device can work normally. The transmission device in this embodiment mainly refers to a production line for conveying bottled products, such as a transmission chain buffer platform.

[0041] When the transmission device is working normally, the filled bottled products are continuously conveyed to the transmission area of ​​the transmission device, and the trigger rod 3 is placed on the transmission surface in the transmission area. When the bottled products pass through the trigger rod 3, because the entrance inclined rod section 31 is an inclined rod, the bottled products will change their movement direction after encountering the entrance inclined rod section 31, and will generate a certain thrust on the trigger rod 3; the above-mentioned preset thrust corresponds to the total thrust generated by a preset number of bottled products on the trigger rod 3. When the number of bottled products passing through the trigger rod 3 is less than the preset number, the trigger rod 3 will not be pushed out to the preset position (that is, the blocking plate 21 is away from the through hole 121). position), the bottled product continues to move forward along the sliding straight rod section 32 after being diverted by the inlet oblique rod section 31; when the number of bottled products passing through the trigger rod 3 (that is, the number of bottled products passing within the length range of the trigger rod 3) reaches a preset number, the trigger rod 3 will be pushed out of the transmission device, pushing the second end of the thrust rod 2 to move toward the second side of the support frame 1. At this time, the push-type transmission control device is in the second working state, the trigger rod 3 is pushed out of the transmission area, the blocking plate 21 is away from the through hole 121, the laser directly emitted by the electric eye sensor is no longer blocked, and the controller of the transmission device will control the transmission device to stop.

[0042] Therefore, the push-type transmission control device in the present application is mainly used in the transmission device of bottled products. Through the pure mechanical structure and the cooperation with the electric eye sensor arranged on the transmission device, the push rod 2 is pushed to move by relying on the thrust of the bottled product on the trigger rod 3. When the number of bottled products passing through the trigger rod 3 reaches a preset number, the push rod 2 can be pushed out to the blocking plate 21 away from the through hole 121, so that the laser directly emitted by the electric eye sensor is no longer blocked; the signal triggering of the electric eye sensor is realized by the pure mechanical structure, which effectively avoids the bottled product in production accidentally triggering the electric eye signal and causing the transmission device to stop, and there is no need for the operator to always watch the production in front of the transmission device, which reduces the labor intensity and effectively avoids the extrusion deformation caused by a large number of bottled products piling up, thereby greatly improving the product quality.

[0043] In a specific implementation, the above-mentioned push rod 2 should be ensured to be pushed only under a preset thrust. In one embodiment, the push rod 2 can be an elastic rod, the material of which has a certain elasticity, and its first end is fixedly connected to the support frame 1. Relying on its own elastic force, the bottled product pushes the push rod 2 to move through the trigger rod 3 under a preset thrust.

[0044] In another preferred embodiment, the first end of the push rod 2 is pivotally connected to the second end of the support frame 1, and the direction of the pivot axis at the pivotal connection is parallel to the conveying direction V. In this embodiment, the push rod 2 is composed of a plurality of bent rods spliced ​​in sequence, or the push rod 2 is an arc-shaped rod. By changing the number and / or bending angle of the bent rods, or by changing the curvature and size of the arc-shaped rod, the push rod 2 can generate the required thrust size and change during the pushing process to adapt to the transmission of different quantities of bottled products.

[0045] Taking the case that the thrust rod 2 adopts a multi-section bending rod, the folding arc between two adjacent bending rods can be the same or different. The specific number of bending rods and the angle between two adjacent bending rods are determined according to the actual required preset thrust. For example, for bottled products applied to small bottles of yogurt, the folding arc between two adjacent bending rods can be the same or different. Figure 1 and Figure 4 As shown in the figure, the thrust rod 2 includes a first bending rod 22, a second bending rod 23, a third bending rod 24 and a fourth bending rod 25 which are bent and connected in sequence from the first end to the second end thereof, and a blocking plate 21 is arranged on the second bending rod 23; the length of the first bending rod 22 is 8-10 cm, the length of the second bending rod 23 is 10-12 cm, the length of the third bending rod 24 is 7-9 cm, the length of the fourth bending rod 25 is 3-5 cm, the angle between the first bending rod 22 and the second bending rod 23 is 160-170°, the angle between the second bending rod 23 and the third bending rod 24 is 90°, and the angle between the third bending rod 24 and the fourth bending rod 25 is 160-170°.

[0046] In a specific example, the lengths of the first bending rod 22, the second bending rod 23, the third bending rod 24 and the fourth bending rod 25 in the four sections of the thrust rod 2 are 8 cm, 10 cm, 7 cm and 3 cm respectively, the angle between the first bending rod 22 and the second bending rod 23 is 160°, the angle between the second bending rod 23 and the third bending rod 24 is 90°, and the angle between the third bending rod 24 and the fourth bending rod 25 is 160°. Each bending rod adopts a rectangular plate body with a thickness of 0.5 cm. The preset thrust required for the thrust rod 2 to be pushed up (leaving the electric eye sensing area, i.e., leaving the area between the two through holes 121) is 2N, and the thrust for a bottled product to pass through the trigger rod 3 is 0.2N. That is to say, when less than 10 bottles of bottled products pass through the control device, although the thrust rod 2 of the control device will be continuously pushed a little bit, it will not be pushed to the blocking plate 21 away from the through hole 121, then the induction electric eye will not be triggered, and the production line will operate normally.

[0047] If the rear-end packaging equipment stops, and there are a large number of bottled products on the transmission platform, when there are more than 10 bottled products, the thrust rod 2 will be pushed up to the blocking plate 21 away from the through hole 121, and the laser directly emitted by the electric eye sensor will no longer be blocked (specifically, the controller of the transmission device receives the signal from the electric eye sensor and controls the transmission device to stop, and the filling machine connected to the transmission device will also stop accordingly).

[0048] Further preferably, refer to Figure 2 and Figure 5 The trigger rod 3 also includes an outlet oblique rod section 33, a first end of the outlet oblique rod section 33 is connected to the second end of the sliding straight rod section 32, and the second end of the outlet oblique rod section 33 extends obliquely from the first side to the second side along the conveying direction V.

[0049] Generally, the outlet oblique rod section 33 and the inlet oblique rod section 31 are symmetrically arranged at the two ends of the sliding straight rod section 32 , and the second end of the thrust rod 2 is connected to the midpoint of the sliding straight rod section 32 .

[0050] The entire trigger rod 3 is designed to be divided into three sections: the entrance oblique rod section 31: the main function is for the bottled product to enter the area. Since the entrance oblique rod section 31 is inclined, the bottled product moving in a straight direction changes its direction of movement after encountering the entrance oblique rod section 31. Due to the interaction of forces, the trigger rod 3 is pushed backward, and then the thrust rod 2 is pushed backward. The sliding straight rod section 32: the bottled product continues to slide along the sliding straight rod section 32 after the turning effect of the entrance oblique rod section 31. The exit oblique rod section 33: the bottled product continues to slide through the sliding straight rod section 32 and enters the exit oblique rod section 33.

[0051] When the number of bottled products passing through the trigger rod 3 is less than the preset number, the trigger rod 3 is continuously pushed backwards under the force of each bottled product, but the electric eye signal will not be triggered at this time; when the number of bottled products corresponding to the trigger rod 3 reaches the preset number, the electric eye signal will be triggered (i.e., the laser emitted by the electric eye sensor is no longer blocked), and the transmission device stops. At this time, there are bottled products at the positions corresponding to the entrance inclined rod section 31, the sliding straight rod section 32, and the exit inclined rod section 33, and most of the bottled products are located in the exit inclined rod section 33. When designing the preset thrust and the bending angle of the trigger rod 3, it will be designed according to the size, capacity, etc. of the bottled products to ensure that the bottled products continuously turn through the entrance inclined rod section 31, slide along the sliding straight rod section 32, and then enter the exit inclined rod section 33. The thrust rod 2 will be pushed backwards to the preset position (i.e., the position where the blocking plate 21 is away from the through hole 121) only when the number of bottled products corresponding to the trigger rod 3 reaches the preset value.

[0052] When the conveyor stops, the operator cannot clean the products manually. At this time, the machine will be forced to start, and the conveyor will transport and clean the accumulated products. The conveyor device generally used to convey bottled products is a conveyor chain buffer platform, and the conveying surface of its conveying area is composed of multiple parallel columns of conveyor chains. Each column of conveyor chains is composed of multiple conveyor plates spliced ​​along the conveying direction V. Each column of conveyor chains can be started separately or simultaneously.

[0053] When the transmission device is forced to start again after stopping, each row of conveyor chains will start separately to quickly clean up the accumulated products. When the conveyor chain next to the conveyor chain near the control device is turned on, the moving bottled products will drive the bottled products on the conveyor chain near the control device forward by the rolling friction of the adjacent bottled products on the left and right, so as to speed up the cleaning.

[0054] Since there is a gap between the side protection plate of the transmission device and the top surface of the transmission platform of the transmission device, after the conveying chain near the control device is forced to start, the bottom of the bottled product is easily unstable under the action of inertia, and it is easy to tilt and get stuck in the above-mentioned gap, affecting the product quality. With the conveying action of the conveying chain, the number of bottled products corresponding to the outlet inclined rod section 33 will first continue to decrease, and the trigger rod 3 will continue to move inward; after the above-mentioned outlet inclined rod section 33 is set, this section can provide a certain support force for the bottom of the bottled product to prevent the bottled product near the control device from suddenly tilting and getting stuck in the gap due to the unstable bottom when the machine is forced to start to clean the product; the above-mentioned sliding straight rod section 32 also has a certain support effect on the bottled product; through the support effect of the inlet inclined rod section 31 and the sliding straight rod section 32, it can effectively prevent the product from being damaged and ensure the product quality.

[0055] In addition, when the bottled products pass through the entrance oblique rod section 31, they will automatically change their running direction and enter the sliding straight rod section 32. On the one hand, the steering effect of the entrance oblique rod section 31 on the bottled products can slow down the advancement of the bottled products. On the other hand, relying on the rolling friction between the left and right adjacent bottled products, the spacing between the bottles can be automatically adjusted to avoid mutual squeezing between the bottles. Setting the length and angle of the entrance oblique rod section 31 and the sliding straight rod section 32 is the key point to ensure that the bottled products are pulled apart, and the specific length and angle are determined according to actual needs.

[0056] In this embodiment, the length of the sliding straight rod section 32 is 18-22 cm, the lengths of the entrance oblique rod section 31 and the exit oblique rod section 33 are both 9-13 cm, and the angles between the entrance oblique rod section 31 and the exit oblique rod section 33 and the sliding straight rod section 32 are both 150-170°.

[0057] For example, when applied to bottled products such as small bottles of yogurt, the lengths of the inlet oblique rod section 31, the sliding straight rod section 32 and the outlet oblique rod section 33 are 11 cm, 20 cm and 11 cm respectively, and the angles between the inlet oblique rod section 31 and the sliding straight rod section 32 as well as between the sliding straight rod section 32 and the outlet oblique rod section 33 are both 160°; the cross-section of the trigger rod 3 is circular, and each section is a circular rod with a diameter of 0.3 cm.

[0058] Furthermore, the support frame 1 includes a vertically arranged back plate 11 and two side plates 12 symmetrically arranged on both sides of the back plate 11, two through holes 121 are respectively opened at the bottom of the two side plates 12, and the first end of the thrust rod 2 is connected to the top of the two side plates 12; a long hole 111 is also provided on the back plate 11, and the length direction of the long hole 111 is arranged along the vertical direction, and a fastener can be inserted into the long hole 111.

[0059] Generally, the first end of the support frame 1 along the vertical direction is its lower end, and the second end is its upper end, and the first end of the thrust rod 2 is connected to the upper end of the support frame 1. The upper part of the support frame 1 is a rotating fixed part, which is used to connect the end of the thrust rod 2 to facilitate the rotation of the thrust rod 2. The above-mentioned long hole 111 is located in the middle of the support frame 1, and the middle of the support frame 1 is an adjustment area. After adjusting the entire support frame 1 to a suitable height, fasteners (such as bolts) are inserted into the long hole 111 to connect with the side protective plate of the transmission device, so that the support frame 1 can be fixed. The size of the support frame 1 is determined according to needs. For example, in this embodiment, the height of the support frame 1 along the vertical direction is 15 cm, and the width along the conveying direction V is 3 cm.

[0060] The lower part of the support frame 1 is the electric eye sensing area, which is used to fix the electric eye sensor through the through hole 121. The back and forth swing of the thrust rod 2 can drive the blocking plate 21 to block or not block the through hole 121; when the blocking plate 21 blocks the through hole 121, it will block the laser emitted by the electric eye sensor, and the direct signal of the electric eye sensor will be blocked. At this time, the transmission device operates normally; when the bottled product squeezes and pushes up the thrust rod 2, the blocking plate 21 is lifted up and leaves the electric eye sensing area, and the through hole 121 is no longer blocked, and the direct signal of the electric eye sensor will no longer be blocked, and the transmission device stops running.

[0061] The materials of the support frame 1 , the thrust rod 2 and the trigger rod 3 can be determined as required. In this embodiment, the materials of the support frame 1 , the thrust rod 2 and the trigger rod 3 are all stainless steel.

[0062] In summary, the push-type transmission control device in this embodiment has the following advantages:

[0063] (1) It is made of three parts: a support frame 1, a push rod 2 and a trigger rod 3. It has a simple structure and is easy to process. The push rod 2 controls whether the laser directly emitted by the electric eye sensor is blocked by lifting or lowering to determine whether the transmission device should be shut down. The support frame 1 is used to position the push rod 2, and can be adjusted up and down as a whole to adjust the installation height on the side of the transmission device. The trigger rod 3 is the force triggering area of ​​the milk bag, and controls whether the push rod 2 moves through the outward pushing force of the milk bag. The entire push-type transmission control device constitutes a device for automatically controlling the transmission system. The function of transmission control is realized through the combination of these three parts, and can be used to control the shutdown of the transmission device. This push-type design can accurately control the number of milk bags (i.e., bottled products) to avoid too many milk bags gathering on the transmission platform of the transmission device, causing the transmission device to shut down or jam.

[0064] (2) The entire control device has the function of automatically adjusting the distance between bottles. When the milk bag passes through the entrance inclined rod section 31 of the trigger rod 3, it will automatically change the running direction and enter the sliding straight rod section 32, which can automatically adjust the distance between bottles to avoid squeezing each other. At the same time, the inclined setting of the exit inclined rod section 33 can prevent the milk bag from being suddenly tilted and stuck in the gap under the side guard plate due to the unstable bottom when the machine is forced to start to clean the milk bag, thereby ensuring product quality. In addition, by adjusting the bending angles at both ends of the trigger rod 3 during design and processing, the thrust rod 2 can be adaptively adjusted according to the changes in the size and shape of different products to achieve more flexible transmission control.

[0065] (3) The entire control device has an automatic recovery function. The thrust rod 2, which is composed of a multi-section bending rod or an arc-shaped rod, will automatically restore to its original state when no bottled product passes through, thereby ensuring normal production. At the same time, when the thrust rod 2 adopts a multi-section bending rod segment folding design, different folding arcs can be used between each part, so that the thrust rod 2 can generate the required thrust during the pushing process. During production design, the size of the preset thrust can be changed by adjusting the length and angle of each section of the bending rod in the thrust rod 2, by adjusting the size of the blocking plate 21, and by adjusting the inclination angle of the inlet inclined rod section 31, so as to flexibly adjust the preset thrust size and transmission speed, improve applicability, and meet the transmission of different numbers of milk bags.

[0066] (4) The entire control device is mainly aimed at the production lines of plastic bottled and glass bottled products. Considering the current market situation, about 88.3% of beverages and milk products are packaged in plastic bottles or glass bottles. These products usually have smooth bottoms and are round or square, which can easily squeeze each other on the production line, resulting in packaging damage and product quality problems. Therefore, the improvement of this application has a great market demand; through this control device, the damage rate of bottled products can be effectively reduced, the packaging quality can be improved, and the downtime on the production line can be reduced; the improvement of this application enables the control device to adjust the thrust and position as needed during design to adapt to bottled products of different sizes and shapes.

[0067] By combining the purely mechanical structure of the control device itself with the controller and electric eye sensor of the transmission device, automatic control can be achieved, which can realize efficient operation of the production line and reduce errors in human operation; the improvement of this application can also integrate data acquisition and analysis functions as needed, and by monitoring and analyzing the operation of bottled products on the production line, obtaining key data in real time and performing fault diagnosis, it can help the production line to continuously optimize and improve production efficiency.

[0068] The improvements of this application have broad market prospects in the production lines of plastic bottled and glass bottled products. They can improve packaging quality, reduce product damage, improve production efficiency, and provide intelligent monitoring and control capabilities for the production line.

[0069] (5) The modified automatic controller of the transmission device avoids equipment shutdown caused by the wrong triggering of the electric eye signal by milk bags during production, reducing operating losses by 0.1%. At the same time, it avoids the extrusion and deformation caused by the accumulation of a large number of milk bags, greatly improving product quality.

[0070] Furthermore, the present application also provides a transmission device, including a transmission platform, an electric eye sensor and the above-mentioned push-type transmission control device; the top surface of the transmission platform constitutes a conveying area, and side protection plates are provided on both sides of the top surface of the transmission platform, and a gap is left between the bottom of the side protection plate and the top surface of the transmission platform; the support frame 1 is detachably arranged on the outer wall of the side protection plate, and the second end of the thrust rod 2 can extend into or out of the conveying area through the gap.

[0071] The transmission device is installed with the above-mentioned control device, which has the same advantages as the control device and will not be described in detail here.

[0072] In practical applications, the transmission device further includes a controller; the controller is electrically connected to the electric eye sensor and the driving device of the transmission device.

[0073] The above-mentioned transmission device can be, for example, a transmission chain buffer platform, and multiple rows of conveyor chains are arranged in parallel on the top surface of the transmission platform, and the multiple rows of conveyor chains constitute a conveying area. The specific structure of the transmission device and the structure of the electric eye sensor are both existing structures. The improvement of this application mainly lies in the structure of the control device and the application of the control device to the transmission device to control whether the signal of the electric eye sensor is blocked, thereby facilitating the controller of the transmission device to control the transmission device to stop.

[0074] Furthermore, a force sensor is provided on the thrust rod 2, and the controller is electrically connected to the force sensor. On the basis of the purely mechanical structure of the control device, a force sensor is added to detect the force magnitude of the thrust rod 2. When the thrust received by the thrust rod 2 reaches the preset thrust, the controller controls the driving device of the transmission device to stop. The force magnitude of the thrust rod 2 is monitored by the force sensor to monitor the number of milk bags on the transmission platform and to provide real-time feedback to the controller, thereby achieving more precise transmission control.

[0075] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
