Description

Conveying device with jacking structure

Technical Field

The utility model belongs to the technical field of gas meter production, and particularly relates to a conveying device with a jacking structure.

Background

The base meter of the gas meter is a lightweight shell structure for workers in the processing process. Therefore, the gas meter is easily shifted or even dropped in the gas meter processing operation. For example, when the code is attached to the surface of the gas meter and the code is printed, if the printed code is attached to the side surface of the gas meter, a pushing force is applied to the side surface of the gas meter, so that the gas meter is laterally moved. In the same way, in other processes requiring side processing, the gas meter is easily displaced or falls, resulting in damage or production line failure.

Therefore, the problem that the gas meter is easy to be stressed and offset in the processing process exists in the prior art, and the stability of automatic processing is reduced.

Disclosure of Invention

The utility model aims to provide a conveying device with a jacking structure, which is used for solving the problem that a gas meter is easy to deviate in the processing process.

In order to solve the technical problems, the utility model is realized by the following technical scheme:

the utility model provides a conveyor with jacking structure, jacking structure includes jacking platform and a elevating gear, the jacking platform with the elevating gear top is connected, the minimum height of jacking platform top surface is not higher than conveyor carries the height of face, jacking platform top surface is provided with the vacuum adsorption mouth. The conveying device is used for conveying the product, and when the product is conveyed to the jacking device, the product can be lifted through the jacking structure, so that the product is separated from the conveying device, and the product is jacked to a position suitable for processing. The vacuum adsorption port on the top surface of the thimble structure can form negative pressure, and the product is adsorbed on the jacking platform in a vacuum adsorption mode, so that the product cannot easily displace when being processed. After the processing is finished, the jacking structure descends to the original position, the vacuum adsorption port stops adsorbing, and the product can move along the original conveying direction and enter the downstream process. In the working process, the effect of adsorbing the product on the jacking platform is achieved through the adsorption effect of the vacuum adsorption port on the product. Thereby solving the problem that the product is easy to shift in position in the processing process.

Therefore, a gap is arranged in the middle of the transmission mechanism, so that the waist line is positioned in the gap, and the gas meter with the waist line can be horizontally placed on the transmission device without being in an inclined state due to the support of the waist line. The contact area between the gas meter and the transmission device in the flat state is larger, so that the movement resistance on the transmission device is larger, and the dislocation cannot be easily caused. And the gas meter in the flat state is also easier to be positioned and grasped by the automatic structure.

The conveying device is provided with a vacuum adsorption device, and the vacuum adsorption device is connected with the vacuum adsorption port through a pipeline. The suction force of the vacuum suction port is provided by a vacuum suction device. The jacking platform is internally provided with a ventilation channel, one end of the ventilation channel is arranged at the top of the jacking platform and is provided with an adsorption structure such as a vacuum chuck, and the other end of the ventilation channel is arranged at the bottom or the side surface of the jacking platform and is provided with a pipeline joint and other structures. The vacuum adsorption device adopts equipment such as a vacuum pump and the like, and is connected with a pipeline joint on the jacking platform through a pipeline. When the vacuum adsorption device is started, the vacuum adsorption port can form negative pressure, so that the product is adsorbed and fixed.

The conveying device is a belt conveyor, and the belt conveyor comprises at least two conveying belts. The belt conveyor is selected because the friction force between the conveyor belt and the surface of the gas meter is larger, and compared with the roller conveyor, the conveyor belt cannot wear the surface of the gas meter.

Under overlooking view, the jacking structure is located in the middle of the belt conveyor, and conveying belts are arranged on two sides of the jacking structure. The two ends of the gas meter are respectively arranged on the conveying belts at the two sides of the jacking structure, and when the conveying belts convey the gas meter to the upper part of the jacking structure, the jacking structure can be lifted upwards, so that the gas meter is jacked away from the conveying belts. The jacking structure jacks up the gas meter to a processing position, and after the processing position finishes processing the gas meter, the jacking structure descends to the lowest position, so that the gas meter is put back to the belt conveyor. The jacking structure is arranged between the two conveying belts, so that the jacking structure is positioned at the lower side of the gravity center of the gas meter, and the jacking operation of the gas meter can not influence the operation of the conveying belts.

Because the shells of the gas meters of various types are formed by welding the shell of the upper half part and the shell of the lower half part. In addition, in order to make the welded shell more stable, an outwards folded waist line is usually formed at the connecting position, so that the stability of welding is improved. Therefore, the middle part of the gas meter of various types is provided with the annular convex waist line. In order to enable the gas meter to lie flat on the conveyor, the conveyor is therefore provided with a plurality of conveyor belts, so that the waist line can be located in the gap of the conveyor belts. In order to avoid the gas meter from deviating to two sides on the conveying belt, the conveying mechanism is further provided with a limiting strip, the top of the limiting strip is provided with a first limiting groove, the top of the jacking structure is provided with a second limiting groove, the length directions of the first limiting groove and the second limiting groove are parallel to the conveying direction of the conveying device, and the central line extension line of the butt joint position of the first limiting groove and the second limiting groove coincides.

The first limiting groove is used for limiting the waist line of the gas meter, and when the waist line is positioned in the first limiting groove, the left-right movement range of the waist line is limited in the first limiting groove, so that the gas meter position is limited from the left side and the right side of the conveying device. In addition, in order to prevent the waist line from affecting the jacking action of the jacking structure, the middle part of the jacking structure is also provided with a second limiting groove. The waist line of the gas meter can be positioned in the second limiting groove, and the gas meter is not in an inclined state due to the support of the waist line positioned in the middle.

The central line extension lines of the butt joint positions of the first limiting groove and the second limiting groove coincide, so that the waist line can smoothly enter the second limiting groove from the first limiting groove, or the waist line can smoothly enter the first limiting groove from the second limiting groove. That is, the gas meter can smoothly move to the jacking platform and also can smoothly move from the jacking platform to the conveying line.

The first limiting groove penetrates through two ends of the limiting strip, the second limiting groove penetrates through two ends of the jacking platform, and guide openings are formed in two ends of the first limiting groove and two ends of the second limiting groove. The action of the guiding opening is to guide the movement direction of the waist line, when the waist line obliquely enters the other limiting groove, the waist line can be propped against the side face of the guiding opening, and the side face of the guiding opening can smoothly guide the waist line into the corresponding limiting groove, so that the problem of clamping the waist line between different limiting grooves can be solved, and the working stability of the limiting groove is improved.

Still including keeping off and stopping the structure, keep off and stop the structure and be located the climbing structure side, keep off and stop the structure and include dog and second elevating gear, the dog is connected with second elevating gear top, the minimum height of dog is not higher than the height of climbing platform top surface. The gas meter is large in size and small in mass, so that when the gas meter is transported by the conveying device, if the gas meter is directly jacked up by the jacking structure, the gas meter is likely to slide for a certain distance and turn forward. Therefore, under the effect of the stop block, the gas meter can be stopped by the stop structure, and then lifted upwards by the lifting structure. Under the cooperation of the stop structure and the jacking structure, the technical effect of stopping before jacking can be achieved, and the problem that the gas meter can move forward and turn over in the jacking process is solved.

The conveying device is provided with a driving mechanism, and all conveying belts are synchronously driven by the driving mechanism. All conveyor belts are driven by the same drive means in order to equalize the speeds of all conveyor belts. All the conveying belts have the same speed, so that the gas meter cannot shift due to different speeds at two sides, and the stability of the gas meter in the conveying process is ensured.

Detailed Description

The technical scheme of the utility model is clearly and completely described by a specific implementation mode of the embodiment of the utility model with the aid of the attached drawings.

Referring to fig. 1-4, the present utility model is a conveying device with a lifting structure, where the conveying device is a belt conveyor provided with two conveying belts 1, so that a waist line of a gas meter is not directly supported on a conveying surface of the conveying structure in a conveying process, so that the gas meter with the waist line can be horizontally placed, and stability of the gas meter in the conveying process is ensured.

In order to further ensure the stability in the transportation process of the gas meter, the speed of the two conveying belts 1 needs to be ensured to be the same, and the deflection of the gas meter on the conveying belts 1 caused by different speeds of the different conveying belts 1 is avoided. Thus, the drive wheels for all drive conveyor belts 1 are connected to the same shaft, which is driven by a motor on the belt conveyor. The motor is the drive on the conveyor belt 1.

The number of the conveying belts 1 is preferably even, so that the same number of the conveying belts 1 at the two sides of the limiting groove is ensured, the bearing capacity of the conveying belts 1 at the two sides of the limiting groove is the same, the stable conveying of the gas meter is ensured, and the gas meter is prevented from being caused by uneven bearing of the conveying belts 1.

Two conveyer belt 1 between set up spacing 6, spacing 6 is fixed on band conveyer's frame construction's crossbeam, spacing 6 top has set up first spacing groove 7, the both ends of spacing 6 are run through to first spacing groove 7. The first limiting groove 7 is used for positioning the waist line of the gas meter, so that the gas meter is prevented from moving randomly in the left-right direction of the belt conveyor. The movement range of the gas meter in the left-right direction, namely the difference between the width of the first limiting groove 7 and the thickness of the waist line, is controlled by the first limiting groove 7 by taking the conveying direction of the belt conveyor as the front.

In order to be convenient for put into first spacing groove 7 with the stringing part, consequently the width of first spacing groove 7 is greater than the thickness of stringing, has reduced the precision of placing the gas table to band conveyer, is convenient for automation equipment operation.

The middle part or the terminal of band conveyer are provided with climbing structure 2, climbing structure 2 is used for upwards jacking up the gas table of passing by, makes the gas table remove to the position that is fit for processing and carries out processing.

When the lifting structure 2 is located in the middle of the belt conveyor, then the width of the lifting structure 2 is smaller than the distance between the two conveyor belts 1.

When the lifting structure 2 is located between two belt conveyors, then the distance between the two belt conveyors is smaller than the dimension of the gas meter in the conveying direction. The purpose of this arrangement is that when the lifting structure 2 lowers the gas meter, the gas meter is at least subjected to the conveying action of the belt conveyor, so that the gas meter can stably move towards the downstream process under the action of the belt conveyor.

The jacking construction 2 comprises a jacking platform and a first lifting device. The first elevating means is vertically disposed so that the first elevating means can be extended or shortened in a vertical direction. The jacking platform is fixed at the top of the first lifting device, and moves upwards when the first lifting device stretches, and moves downwards when the first lifting device shortens. And when the first lifting device is shortened to be shortest, the top surface of the jacking platform is lower than the height of the conveying belt 1, so that the gas meter is prevented from being blocked during transportation when the tension of the conveying belt 1 is reduced or the stress is sunken.

The first lifting device can be an electric cylinder or an air cylinder. The electric cylinder has the advantage of more accurate control of the jacking distance.

The top of jacking platform is provided with the vacuum adsorption mouth, and the effect of vacuum adsorption mouth is provided negative pressure, adsorbs the gas table of jacking at the top of jacking platform. The vacuum adsorption port adopts a vacuum chuck 3, and the vacuum chuck 3 is utilized to realize the adsorption of the gas meter.

Preferably, the top end of the vacuum chuck 3 is slightly higher than the top surface of the jacking platform, so that the vacuum chuck 3 can be stably contacted with the gas meter. The top end of the vacuum sucker 3 is pressed and deformed when contacting the gas meter, and the gas meter is not caused to deviate. Before the gas meter is processed, the vacuum chuck 3 adsorbs and fixes the gas meter, and the thrust generated during processing is avoided pushing away the gas meter from the jacking platform.

The bottom end of the vacuum chuck 3 is fixed on the jacking platform, so the jacking platform is provided with a ventilation channel for installing the vacuum chuck 3, and the ventilation channel is a pore canal penetrating through the top surface and the bottom surface of the jacking platform. The top end of the ventilation channel is provided with a vacuum chuck 3, the bottom end of the ventilation channel is provided with a pipe joint, the pipe joint is connected with a vacuum pump through a pipeline, and the vacuum pump provides negative pressure for the vacuum chuck 3.

The jacking structure 2 is used for jacking the gas meter from the lower part, and the surface of the gas meter is provided with an annular raised waist line, so that the top surface of the jacking platform is provided with a second limit groove 5 in order to enable the gas meter to be horizontally arranged on the jacking structure 2. The second limiting groove 5 corresponds to the position of the first limiting groove 7, so that the waist line can smoothly slide into the second limiting groove 5 from the first limiting groove 7 and can smoothly slide into the first limiting groove 7 at the downstream from the second limiting groove 5.

The width of the second limit groove 5 is the same as that of the first limit groove 7. In order to enable the butt joint of the second limiting groove 5 and the first limiting groove 7 to be smoother, the waist line is prevented from being clamped at the end part of the limiting strip 6 or the side surface of the jacking platform in the butt joint process, and therefore guide openings are formed in the end parts of the first limiting groove 7 and the second limiting groove 5.

In a top view, the guide openings are chamfers processed at the end parts of the first limit groove 7 and the second limit groove 5.

The waist line is the annular protruding structure in the middle part of the gas meter, so that when the waist line is positioned in the first limit groove 7 or the second limit groove 5, the angle of the gas meter is limited by the first limit groove 7 or the second limit groove 5. And the automatic structure identification and grabbing are more convenient. That is, the first limit groove 7 or the second limit groove 5 also has a positioning function for the gas meter.

Because the waist line is formed by bending the shell of the gas meter, the root of the waist line is provided with an arc-shaped bending part, and the thickness of the position is thicker. Therefore, in order to avoid that the root of the waist line is clamped on the limiting groove and the gas meter cannot be transported by the conveying belt 1, the top edge of the limiting groove is processed with a widening step, so that the width of the top of the limiting groove is wider, and the root of the waist line is prevented from being clamped on the limiting groove.

Since the gas meter is lifted up by the lifting structure 2 during transportation. In order to avoid that the gas meter continuously moves forward under the inertia effect and falls off due to the fact that the front end loses support when being lifted, a stop structure 4 is arranged on the side face of the lifting structure 2. The stop structure 4 comprises a stop block and a second lifting device. The dog is installed on the top of the second lifting device, and the lifting is controlled by the second lifting device.

The second lifting device can adopt an electric cylinder or an air cylinder. The stroke of the second lifting device is not required to be long, and only the stop block is required to be jacked up for a certain distance and the forward movement of the gas meter is blocked.

The stop may be a separate plate or block element or may be an electric cylinder or a piston rod of a cylinder.

When the gas meter is required to be jacked up, the gas meter is firstly blocked by the blocking structure 4, the gas meter is stopped to move forwards, and then the jacking platform is lifted up. The lifting of the stopping structure 4 and the lifting of the lifting structure 2 can be completed within 1s before and after the stopping structure 4, that is, the starting interval between the stopping structure 4 and the lifting structure 2 can be less than 1s.

When the jacking structure 2 jacks up the gas meter, the stop structure 4 also loses effect. The stop arrangement 4 can thus be mounted directly on the frame structure of the belt conveyor. Likewise, the stop structure 4 may also be mounted on the jack-up platform.

And the stop block in the stop mechanism is controlled by the second lifting device, so that the second lifting device is arranged on the belt conveyor or the jacking platform.

Before the jacking platform is completely put down, the second lifting structure needs to be shortened, so that the gas meter is prevented from being blocked from advancing when the gas meter returns to the conveying belt 1 again.

Limiting plates can be arranged on two sides of the conveying device and used for limiting the gas meter without the waist line, and the shell of the gas meter is limited from the left side and the right side through the limiting plates. After the limiting plate is arranged, the limiting plate can be collided when the gas meter moves in the left-right direction, so that the limiting plate can limit the left-right position of the gas meter.

The fixing mode of the limiting plate can be fixed by adopting a fastener such as a screw pin, for example, a screw hole and a pin hole are formed in the side face of the belt conveyor, so that the limiting plate is fixed. The side of the belt conveyor can be provided with clamping grooves such as dovetail grooves, and the limiting plate is provided with a structure matched with the clamping grooves, so that the limiting plate is clamped on the transmission structure.

Similarly, the distance between the limiting plates at the two sides is larger than the length of the gas meter in the left-right direction, so that the gas meter is convenient to put into the transmission structure. And the spacing between the limiting plates at two sides is smaller than the length of the gas meter in the diagonal direction, so that the gas meter is prevented from rotating after collision with the limiting plates.

In order to control the transmission angle of the gas meter, different intervals should be set according to the gas meters of different sizes.

When the machining process is required to be completed through the automation equipment, the position of the gas meter is usually required to be detected, and then the gas meter is positioned, grabbed and machined through the automation equipment. The transmission structure may thus also be provided with detection structures such as sensors or industrial cameras. In order to avoid the limit structure to block the detection structure, the height of the limit structure can be controlled to be about 1cm, so that the limit structure can play a limit role and can also avoid the limit structure from obstructing the detection structure.

The limiting groove structure and the limiting plate structure can be arranged at the same time for the gas meter with the waist line, the limiting plate can be omitted, and the limiting effect and the angle positioning effect on the gas meter can be realized only by positioning the limiting groove. The gas meters of partial models have no waist line structure, so that the limit grooves cannot limit the gas meters, and a limit plate is required to be installed for limiting under the condition.
