Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment discloses a detection device for tire building equipment and tire building equipment including the same, and whether the delivered materials are folded (stacked, piled up), extruded or blocked and stacked is detected in the feeding process of the materials. As shown in fig. 1, the tire building apparatus includes a feeding system including a feeding frame 20, and the detecting device is mounted on the feeding frame 20.

As shown in fig. 2 to 6, the detecting device includes a detecting component 1 and a supporting component 2, wherein the supporting component 2 is located above the material 10 to be detected and is installed on a supply frame 20. When the thickness of the material 10 to be detected exceeds a set value, the supporting piece 2 can swing or move linearly, and the detection assembly 1 is used for knowing the swinging or linear movement of the supporting piece 2, so that the condition that the material 10 to be detected is stacked, extruded or blocked and stacked is accurately judged, and particularly the edge part of the material can be accurately detected to be folded.

The support 2 is preferably a U-shaped frame, the ends 21 of which are hinged to the supply frame 20 by means of a respective seated bearing. The balance wheel mounting shaft 31 is hinged at both ends to the support 2, and the balance wheel 32 is provided on the balance wheel mounting shaft 31 via a balance wheel support bar 33. The support 2 is also provided with an upper limit adjusting bolt 23 and a lower limit adjusting bolt 24 which are aligned with the balance wheel support rod 33, the upper limit adjusting bolt 23 and the lower limit adjusting bolt 24 both penetrate through the support 2 and extend downwards for a certain distance, and the lengths of the upper limit adjusting bolt 23 and the lower limit adjusting bolt 24 which extend downwards are not equal.

As shown in fig. 4, the balance wheel mounting shaft 31 passes through the balance wheel support bar 33 at a position approximately in the middle, and the balance wheel support bar 33 is rotatable around the balance wheel mounting shaft 31; the balance 32 is mounted on one end of the balance support rod 33, and the other end is suspended. The balance support bar 33 is named as a front portion from a position where the balance mounting shaft 31 is connected to a position where the balance 32 is connected, and the tip end where the balance support bar 33 is suspended from the position where the balance mounting shaft 31 is connected to the balance support bar 33 is named as a rear portion. When the balance 32 is at the upper limit, the front part of the balance support bar 33 abuts on the upper limit adjusting bolt 23, and when the balance 32 is at the lower limit, the rear part of the balance support bar 33 abuts on the lower limit adjusting bolt 24.

The downward extending length of the upper limit adjusting bolt 23 and the lower limit adjusting bolt 24 can be adjusted according to the thickness of the material 10 to be detected, so that the material 10 to be detected with different thicknesses can be suitable. Specifically, the lower limit adjustment bolt 24 is screwed to the support frame 2, and the lower end of the lower limit adjustment bolt 24 abuts against the rear portion of the balance support bar 33. When no material 10 to be detected passes through, the lower limit adjusting bolt 24 is screwed so that the lower end of the lower limit adjusting bolt 24 moves toward the feed frame 20, that is, the lower end of the lower limit adjusting bolt 24 presses down the rear portion of the balance supporting rod 33, and the rear portion of the balance supporting rod 33 rotates around the balance mounting shaft 31 so that the front portion of the balance supporting rod 33 is away from the upper surface of the feed frame 20. The balance 32 is far away from the upper surface of the supply frame 20 along with the front part of the balance supporting rod 33, so that a gap h (0 < h < the thickness of the material 10 to be detected) exists between the bottom of the balance 32 and the upper surface of the supply frame 20, the direct contact friction between the balance 32 and the supply frame 20 can be avoided, the balance 32 and the supply frame 20 are protected, and the service life is prolonged. The numerical value of the gap h can be properly adjusted according to the thickness of the material 10 to be detected, and the method is suitable for different material thicknesses.

The balance wheel mounting shaft 31 is provided with a swing rod 34, the support 2 is provided with a photoelectric switch 4, when the balance wheel 32 drives the balance wheel mounting shaft 31 to rotate, the swing rod 34 rotates along with the balance wheel mounting shaft 31, and the swing rod 34 can shield or open a detection head of the photoelectric switch 4. Preferably, the opto-electronic switch 4 is fixedly mounted on the support 2 by means of a Z-shaped structure.

Wherein, the detecting component 1 is preferably a proximity switch, the proximity switch comprises a sensor and a sensing piece, the sensor can be arranged on the supporting piece 2, and the sensing piece is arranged on the feeding frame 20; of course, the sensor may be provided on the supply stand 20 and the sensing member on the support member 2. In this embodiment, the sensor sets up on feed frame 20, and the response piece sets up on support piece 2, and both sets up relatively, guarantees that sensor and response piece can respond to each other fast for measuring result is more accurate. The sensor composing the proximity switch is preferably a displacement sensor, the measurement is accurate, and the manufacturing cost is low.

When the material 10 to be detected is stacked or extruded, the surface thereof is fluctuated (one piece or a section of the material 10 to be detected is bulged), when the thickness of the material 10 to be detected exceeds a certain value, the balance wheel support rod 33 connected to the balance wheel 32 is pressed against the upper limit adjusting bolt 23, so that the balance wheel 32 can not move upwards relative to the support 2 any more, but the upper limit adjusting bolt 23 is pressed and drives the support 2 to rotate around the hinge shaft 22. When support piece 2 is raised by the jack-up, fix proximity switch's on feed frame 20 displacement sensor and fix the response piece on support piece 2 by alternate segregation to certain distance to the response between signal displacement sensor and the response piece disappears, therefore the signal is cut off, and then tire former's controller can judge here according to the signal of being cut off that there is the phenomenon of piling up or crowded material, and give the warning that detects material 10 anomaly, remind operating personnel to detect material 10 and have anomaly.

The sensing member is preferably an iron plate provided on the support member 2 or the supply frame 20, and the manufacturing cost of the fitting is low. When feed frame 20 was made for the iron material, proximity switch's sensor setting was at support piece 2, and feed frame 20 self is the response piece promptly, and the structure is more succinct, and the volume is littleer, has reduced the processing cost.

The proximity switch has high reaction speed, can timely discover and inform an operator to timely process when the material 10 to be detected is folded (stacked) or extruded, prevents the tire forming equipment from being damaged due to the extrusion phenomenon, and can avoid inaccurate fixed length caused by the folding of the material 10 to be detected. The materials 10 to be detected with different thicknesses can smoothly pass through by adjusting the downward extending lengths of the upper limit adjusting bolt 23 and the lower limit adjusting bolt 24, so that the applicability is strong and the application range is wide.

The detection device can detect the stacking or extruding condition of materials while measuring the length and fixing the length, and has comprehensive functions. In addition, often need turn up support piece 2 when detection device overhauls, operating personnel probably forget after overhauing to turn over support piece 2, lead to tire former start-up back detection subassembly to lose its effect. This problem can be solved after setting up proximity switch, because proximity switch is no signal when support piece 2 turns up, and tire building equipment can't start, consequently can remind operating personnel to restore to the correct position the device that overhauls.

A plurality of wobblers 32 may be sequentially provided on the wobbler mounting shaft 31 in the width direction, so that whether the material 10 to be inspected is flat or not can be comprehensively checked. Preferably, three wobblers 32 are provided on the wobbler mounting shaft 31, and the three wobblers 32 are respectively provided at the middle portion and both side end portions of the wobbler mounting shaft 31 for detecting the middle portion and the edge portion of the material such as the fabric and the lining. As long as the middle part and the two side end parts of the material 10 to be detected are flat, the material 10 to be detected is basically flat, and the processing cost of the whole machine is reduced by simplifying the unnecessary structure of the balance 32.

On the basis of the structure, the balance wheel 32 is provided with a return spring, and the return spring can push the balance wheel 32 to return to the original position after the material 10 to be detected completely passes through. Of course, it is also possible to dispense with a return spring, when the material to be detected 10 has all passed the rear balance 32 and has returned to its original position by its own weight.

The working process of the detection device is as follows:

as shown in fig. 5, when no material 10 to be detected passes through, the balance 32 is downward, one end of the balance support rod 33 connected with the balance 32 is lower than one end far away from the balance 32 (i.e. the front part is low and the rear part is high), the oscillating rod 34 is shielded in front of the detecting head of the photoelectric switch 4, in order to avoid damage to the balance 32 or the conveyor belt caused by direct contact of the balance 32 with the conveyor belt on the feeding frame 20, the lower limit adjusting bolt 24 is arranged at a position aligned with the rear part of the balance support rod 33, and the length of the lower limit adjusting bolt 24 is set to abut against the lower limit adjusting bolt 24 when the balance 32 is downward to a set position.

When a normal material 10 to be detected passes through, the balance wheel 32 is jacked up by the material 10 to be detected, one end of the balance wheel support rod 33 connected with the balance wheel 32 is lifted upwards for a certain distance, the balance wheel mounting shaft 31 rotates for a certain angle around the axis, the balance wheel mounting shaft 31 drives the swing rod 34 to rotate around the axis of the balance wheel mounting shaft 31, the swing rod 34 opens a detection head of the photoelectric switch 4, signals are cut off, and the fact that the material 10 to be detected passes through is judged and length counting or timing is started.

As shown in fig. 6, when the passing material 10 to be detected has a stacking or extruding phenomenon, the surface of the material 10 to be detected is much higher than that in the normal state, at this time, the balance wheel support rod 33 abuts on the upper limit adjusting bolt 23, the balance wheel mounting shaft 31 can not rotate around the axis any more, so the balance wheel 32 jacks the support 2 through the balance wheel support rod 33 and the balance wheel mounting shaft 31, the support 2 rotates around the hinge shaft 22, the displacement sensor and the sensing element of the proximity switch are separated, and the abnormal signal of the material 10 to be detected is sent.

This embodiment is used for detection device's of tire former support piece 2 articulates on feed frame 20, support piece 2 can swing or linear motion when the thickness of waiting to detect the material exceeds the setting value, and the detection subassembly can accurately learn to detect piling up or crowded material situation of waiting to detect material 10 according to support piece's swing or linear motion, in time discovers and notifies operating personnel in time to handle, prevents to damage tire former because crowded material phenomenon, can avoid moreover waiting to detect the material folding and lead to the fixed length inaccurate.
