Description

Technical Field

[0001] The present invention relates to a feeding device, which can be used for intermittently conveying parts, and further relates to a pore sleeve embedding device which can include the feeding device. Background Art

[0002] In the production process of tires, a series of processes are performed on rubber materials to achieve tire embryo molding. After the tire embryo is molded, the tire embryo needs to be vulcanized. During the vulcanization process, the air in the inner cavity of the tire mold needs to be discharged. The commonly used method at present is to set an exhaust hole on the tire mold, and the air in the tire mold is directly discharged through the exhaust hole. The exhaust hole is formed by a method such as drilling.

[0003] During the vulcanization of the tire blank, it was found that only providing vent holes for exhaust would cause some problems. For example, during the process of exhausting air from the tire mold, the rubber material used to form the tire is under high temperature and high pressure conditions. At this time, a part of the raw rubber that has not been vulcanized will be squeezed out through the vent holes onto the outer surface of the tire mold. These extruded rubber materials will form rubber hair on the tire tread. When the tire is removed, some of the rubber hair will break in the vent holes, thereby blocking the vent holes. In this way, the exhaust performance of the tire mold is affected in the subsequent production process. In order to ensure the quality of the final tire product, it is necessary to provide an additional process to remove the rubber hair formed on the tire. Therefore, the manufacturing process of the tire becomes complicated.

[0004] In order to avoid this situation, one solution is to arrange an exhaust device in the exhaust hole, for example, one form of the exhaust device is a pore sleeve, which is embedded in the exhaust hole. The structure of the pore sleeve is arranged to allow the air in the tire mold to be discharged, but when the rubber in the mold contacts the pore sleeve, the pressure of the rubber closes the pore sleeve, thereby preventing the rubber from being extruded through the pore sleeve to the surface of the tire mold.

[0005] Under existing technical conditions, the pore sleeve is manually inlaid on the tire mold, such as inlaying the pattern block or side plate of the tire mold. The quality of manual inlay varies from person to person, the technical experience of the operator is very high, and the efficiency of the inlay operation is relatively low.

[0006] One difficulty in achieving the automatic inlaying of the pore sleeve is the automatic feeding of the pore sleeve. In the pore sleeve inlaying operation, since the diameter of the pore sleeve is small, a larger pore sleeve has a diameter of only 1.3 mm, and its external shape is a hollow cylinder with steps. Therefore, it is difficult for the existing device to achieve intermittent feeding control of the pore sleeve.

[0007] Therefore, there is a need for a pore sleeve embedding device capable of performing pore sleeve embedding operations, which can efficiently perform automated operations on the pore sleeve embedding, and in particular can realize automated feeding of the pore sleeve. Summary of the invention

[0008] The present invention is made based on the above problems existing in the prior art. The purpose of the present invention is to provide a pore sleeve inlaying device which can efficiently perform pore sleeve inlaying operations.

[0009] The above-mentioned object of the present invention is achieved by a feeding device. The feeding device comprises:

[0010] A delivery portion, the delivery portion comprising a delivery channel, a first hole extending inwardly from an outer surface of the delivery portion to the delivery channel, and a second hole extending inwardly from an outer surface of the delivery portion to the delivery channel, the first hole being located downstream of the second hole;

[0011] A blocking portion, the blocking portion comprising a blocking member, the blocking member extending into the first hole and being capable of reciprocating in the first hole, thereby extending into and out of the conveying passage;

[0012] a restriction portion, the restriction portion comprising a restriction member, the restriction member extending into the second hole and being capable of reciprocating in the second hole so as to extend into and out of the conveying passage; and

[0013] The driving part is connected with the blocking member and the limiting member to drive the blocking member and the limiting member to reciprocate.

[0014] The feeding device having the above structure can efficiently convey parts such as air hole sleeves, and the feeding device allows intermittent conveying of parts, conveying the required number of parts each time, that is, realizing the control of intermittent feeding of parts.

[0015] The driving of the blocking member and the limiting member by the driving part can make the blocking member and the limiting member move synchronously. For example, the blocking member and the limiting member can be connected to the same driving part and realize synchronous movement through the driving part. Alternatively, two driving parts can be provided, which are respectively connected to the blocking member and the limiting member, and the two driving parts are arranged to run synchronously with each other, so as to realize synchronous movement of the blocking member and the limiting member. Of course, intermittent movement can also be adopted. For example, the blocking member and the limiting member can be respectively connected to two different driving parts, and the two driving parts are independent of each other, and drive the blocking member and the limiting member separately, so that there is a gap between the movements of the two.

[0016] Preferably, a receiving hole is further provided at a position in the conveying channel opposite to the first hole. When the blocking member extends into the conveying channel, the free end of the blocking member can enter the receiving hole. The provision of the receiving hole can provide additional support for the blocking member extending into the conveying channel, reducing the impact of the parts on the blocking member and causing damage to the blocking member. In addition, the receiving hole can also limit the stroke of the blocking member, as described below.

[0017] In other words, the feeding device of the present invention may further include a limiting portion that limits the stroke of the blocking member entering the conveying channel. Among them, the limiting portion may be the closed end of the above-mentioned receiving hole. Or, in another implementation structure, the limiting portion may be a convex ring provided on the blocking member.

[0018] Preferably, the feeding device has two oppositely arranged blocking portions, and the blocking members of the two blocking portions extend into the conveying channel from opposite positions of the conveying portion. Thus, the two blocking members can cooperate with each other to clamp the parts in the conveying channel.

[0019] Preferably, the free end of the limiting member is a limiting end for contacting the parts conveyed by the feeding device, and the limiting end is made of a soft material. In this way, while the limiting member holds the parts against, damage to the limiting member can be avoided.

[0020] Preferably, if the distance between the limiting member and the blocking member along the longitudinal extension direction of the conveying channel is S, and the length of the parts conveyed by the feeding device is L, then the distance and the length satisfy the following relationship: L < S < 2L, and preferably S = (4 / 3 - 5 / 3)L. Through such a dimension setting, it can be ensured that one part is conveyed at a time.

[0021] Preferably, an elastic member is provided on the portion of the limiting member located outside the conveying portion. One end of the elastic member is fixed or abutted on the limiting member, and the other end of the elastic member is associated with the driving portion and can be driven by the driving portion.

[0022] Preferably, the blocking member and / or the limiting member is a cylindrical rod.

[0023] Preferably, a first intermediate transition member is provided between the driving portion and the blocking member of the blocking portion, and the driving force of the driving portion is transmitted to the blocking member through the first intermediate transition member; and / or a second intermediate transition member is provided between the driving portion and the limiting member of the limiting portion, and the driving force of the driving portion is transmitted to the limiting member through the second intermediate transition member. Exemplary forms of the first and second intermediate transition members may be connecting plates, connecting rods, etc. Among them, preferably, the first intermediate transition member is fixedly connected to the second intermediate transition member. Additionally, preferably, the first hole extends from the outer surface of one side of the conveying portion into the conveying channel, and the second hole extends from the outer surface of the other side of the conveying portion into the conveying channel.

[0024] Preferably, the feeding device further comprises an air blowing part for assisting the conveying of the parts, wherein the air blowing part is connected to the conveying part and communicated with the conveying channel, so as to provide a compressed air flow to the conveying channel.

[0025] Preferably, the outlet of the air blowing part is at an angle of less than or equal to 90° to the extending direction of the conveying channel, preferably at an angle of 45 to 80°, and more preferably at an angle of 30 to 60°. Thus, the blown compressed air can be more effectively used to convey parts.

[0026] Preferably, a detection unit is further provided below the conveying channel, and the detection unit is used to detect whether any parts are discharged from the conveying channel.

[0027] The present invention also provides a pore sleeve embedding device, which has the above-mentioned feeding device for outputting the pore sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the drawings only show preferred embodiments of the present invention and do not limit the scope of the present invention. Those skilled in the art can make various obvious modifications, variations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, and the technical features in the described embodiments can be combined arbitrarily without contradiction, and all of these fall within the scope of protection of the present invention.

[0034] In the disclosure of the present invention, the terms "upper", "lower" and the like used to indicate direction or orientation are based on the orientation of the device when in use.

[0035] Figure 1 A perspective view of a feeding device 10 of the present invention is shown, Figure 2 A top view of the feeding device 10 is shown, and Figure 3 A cross-sectional view of the feeding device 10 is shown, thereby illustrating the internal structure of the feeding device 10 .

[0036] As shown in the figure, the feeding device 10 includes a driving part 100, a blocking part 200, a limiting part 300 and a conveying part 400. The blocking part 200 and the limiting part 300 are driven by the driving part 100, thereby applying blocking and limiting effects to the conveying part 400 respectively. Among them, an exemplary embodiment of the driving part 100 is a driving cylinder. In addition, the feeding device 10 also includes an air blowing part 500 connected to the conveying part 400, which is used to help convey the parts in the conveying part 400, such as the air hole sleeve.

[0037] The blocking part 200 includes a blocking member 210, which is driven by the driving part 100 to realize reciprocating motion. For example, when the driving part 100 is specifically a driving cylinder, the blocking member 210 can be directly or indirectly connected to the piston rod of the driving cylinder, thereby can reciprocate with the piston rod of the driving cylinder. Preferably, as shown in the figure, the blocking part 200 also includes a blocking part push rod 220, one end of the blocking part 200 is connected to the output end (for example, the piston rod of the driving cylinder) of the driving part 100, and the other end is connected to the blocking member 210, so that the driving force of the driving part 100 is transmitted to the blocking member 210 via the blocking part push rod 220.

[0038] The blocking member 210 is preferably a cylindrical component, which can be accommodated in a hole formed in the conveying portion 400 and is driven by the driving portion 100 to reciprocate in the conveying portion 400 to intermittently block and release parts in the conveying portion 400 (such as pore sleeves, such as the first pore sleeve 20-1 and the second pore sleeve 20-2 shown in the figure), as disclosed below.

[0039] like Figure 3 As more clearly shown in FIG. 4 , the conveying portion 400 includes a conveying channel 410 and a blocking member perforation (or first hole) 411. The conveying channel 410 is disposed inside the conveying portion 400 along the longitudinal direction (i.e., Figure 3 The blocking member through-hole 411 extends from the lateral outer surface of the conveying channel 410 to the inner wall of the conveying channel 410, and connects the conveying channel 410 with the outside of the conveying portion 400. The extending direction of the blocking member through-hole 411 is at an angle to the extending direction of the conveying channel 410, and is preferably perpendicular to the extending direction of the conveying channel 410.

[0040] The blocking member 210 can extend from the outside into the blocking member through hole 411, and reciprocate between the blocking position and the release position under the driving action of the driving unit 100. When the blocking member 210 is in the blocking position, the blocking member 210 extends into the conveying channel 410 through the blocking member through hole 411, blocking the movement of the parts in the conveying channel 410 downward toward the outlet of the conveying channel 410, and when the blocking member 210 is in the release position, the blocking member 210 retracts toward the outside of the conveying unit 400 and exits the conveying channel 410, thereby allowing the air hole sleeve in the conveying channel 410 to move downward.

[0041] In the blocking position, the blocking member 210 can at least partially extend into the conveying channel 410, as long as the size of the portion of the conveying channel 410 that is not blocked by the blocking member 210 is smaller than the size of the part, thereby ensuring that the part will not fall through the blocking member 210.

[0042] Preferably, a receiving hole 413 is provided on a side of the conveying passage 410 opposite to the blocking member through hole 411. When the blocking member 210 extends into the conveying portion 400, it can extend into the receiving hole 413 all the way.

[0043] The receiving hole 413 serves to limit the movement of the blocking member 210, thereby improving the precision and accuracy of the limit. Furthermore, if the transported parts are subjected to a large thrust, the receiving hole 413 also serves to support the blocking member 210, thereby reducing or avoiding deformation of the blocking member 210 caused by the impact of the parts on the blocking member 210.

[0044] In the case where the accommodating hole 413 is provided, the accommodating hole 413 may be provided as a hole with one end closed, so that the closed end of the accommodating hole 413 serves to limit the blocking member 210 .

[0045] Of course, the receiving hole 413 is optional, and the limiting function of the blocking member 210 can also be achieved in other ways. For example, a limiting structure such as a convex ring can be provided on the blocking member 210, such as a convex ring is provided on the portion of the blocking member 210 located outside the conveying portion 400, and the limiting function is achieved by the mutual contact between the convex ring and the outside of the conveying portion 400. Alternatively, the limiting function can be achieved by controlling the stroke of the driving portion 100.

[0046] The blocking part 200 of the present invention may also adopt other types of implementations. For example, in the blocking position, the blocking member 210 may partially extend into the delivery channel 410 and abut against the pore sleeve, thereby pushing the pore sleeve against the inner wall of the delivery channel 410. In this way, the friction between the pore sleeve and the inner wall of the delivery channel 410 prevents the pore sleeve from continuing to move downward.

[0047] Alternatively, two groups of blocking parts 200 may be provided in the feeding device 10, which are provided on both sides of the conveying channel 410, and the blocking member 210 of each blocking part 200 reciprocates synchronously to clamp the pore sleeve between the two blocking members 210. This method is particularly suitable for parts with a relatively large diameter change along the axial direction. Due to the large change, sometimes it is difficult to ensure that the part is pressed against the inner wall of the conveying channel 410 with only one blocking member 210.

[0048] The limiting part 300 includes a limiting member 310. Like the blocking member 210 of the blocking part 200, the limiting member 310 can also be driven by the driving part 100 to achieve reciprocating motion. Preferably, as shown in the figure, the limiting part 300 also includes a limiting part push rod 320, one end of which is connected to the output end of the blocking part 200, and the other end is connected to the limiting member 310, so as to transmit the driving force of the driving part 100 to the limiting member 310.

[0049] The driving part 100 can synchronously drive the limiting member 310 and the blocking member 210. For example, the limiting member 310 and the blocking member 210 can be connected to the same driving part 100 to achieve synchronous movement of the two. Alternatively, two driving parts 100 that can operate synchronously can be provided, which are respectively connected to the limiting member 310 and the blocking member 210. On the other hand, two driving parts 100 that operate independently of each other can be provided, and these two driving parts 100 drive the limiting member 310 and the blocking member 210 separately, and do not necessarily drive them synchronously, or in other words, there can be a gap between the respective movements of the limiting member 310 and the blocking member 210.

[0050] The limiting member 310 is preferably a cylindrical component that can be accommodated in a hole formed in the conveying portion 400 and is driven by the driving portion 100 to reciprocate in the conveying portion 400 to intermittently limit the parts in the conveying portion 400, as disclosed below.

[0051] like Figure 3 As shown in the figure, a limiting member through hole (or second hole) 412 is also provided in the conveying channel 410, and the limiting member through hole 412 extends from the lateral outer surface of the conveying channel 410 to the inner wall of the conveying channel 410 in a radial direction, and connects the conveying channel 410 with the outside of the conveying part 400. Similar to the blocking member through hole 411, the extension direction of the limiting member through hole 412 also forms an angle with the extension direction of the conveying channel 410, and is preferably perpendicular to the extension direction of the conveying channel 410.

[0052] Preferably, the blocking member through-hole 411 extends inward from one outer surface of the conveying portion 400 to the conveying channel 410, and the restricting member through-hole 412 extends inward from the other outer surface of the conveying portion 400 to the conveying channel 410. The restricting portion push rod 320 is fixedly connected to the blocking portion push rod 220. By using one driving portion 100, the blocking portion 200 and the restricting portion 300 can be driven to alternately enter or exit the conveying channel 410 substantially simultaneously. Thus, stable and precise intermittent feeding is achieved.

[0053] Further, the restricting member through-hole 412 is located upstream of the blocking member through-hole 411 in the part conveying direction in the conveying channel 410, or is located above the blocking member through-hole 411 as shown in the figure, and is separated by a distance S along the longitudinal direction of the conveying channel 410. Preferably, the relationship between the distance S along the longitudinal direction between the restricting member through-hole 412 and the blocking member through-hole 411 and the length L of the part (such as the air hole sleeve) satisfies L < S < 2L. Preferably, the distance S is equal to (4 / 3 to 5 / 3)L, so as to ensure that only one air hole sleeve can pass through the conveying channel 410 and enter the inlaying station or other devices each time feeding occurs.

[0054] The restricting member 310 can extend from the outside into the restricting member through-hole 412 and reciprocate between a restricting position and a passing position under the driving action of the driving portion 100. Among them, when the conveying channel 410 is in the restricting position, the restricting member 310 extends into the conveying channel 410 through the restricting member through-hole 412 and clamps the part in the conveying channel 410 to prevent the part from moving downward towards the outlet of the conveying channel 410. When the restricting member 310 is in the passing position, the restricting member 310 retracts towards the outside of the conveying portion 400 and exits the conveying channel 410, thereby allowing the air hole sleeve in the conveying channel 410 to move downward into the space between the restricting member 310 and the blocking member 210 in the conveying channel 410.

[0055] The end of the restricting member 310 facing the conveying channel 410 is the restricting end 312, and the restricting end 312 is used to contact the part and press the part against the inner wall of the conveying channel 410. Preferably, the restricting end 312 is made of a soft material such as rubber or silica gel to avoid damaging the part when restricting the part.

[0056] Preferably, an elastic member 330 is provided on the part of the restricting member 310 located outside the conveying portion 400. The elastic member 330 is, for example, a spring sleeved on the restricting member 310, etc. One end of the elastic member 330 is fixedly positioned relative to the restricting member 310. For example, it can be fixedly connected to the restricting member 310 or can abut against the protrusion 311 on the restricting member 310 ( Figure 2 ).

[0057] The other end of the elastic member 330 is a free end, which can be actuated to compress the elastic member 330. For example, the free end of the elastic member 330 can be associated with the driving part 100, so as to be compressed by the driving of the driving part 100. For example, in the structure shown in the figure, the fixed end of the elastic member 330 sleeved on the limiting member 310 abuts on the protrusion 311, and the free end thereof abuts on the limiting part push rod 320. In addition, the limiting member 310 is movably connected to the limiting part push rod 320, for example, passing through a hole on the limiting part push rod 320 and can move in the hole. One end of the limiting member 310 extending from the limiting part push rod 320 can be threaded and screwed with a nut 313, and the compression degree of the elastic member 330 can be adjusted by screwing the nut 313. Thus, the nut 313 acts as an adjusting member of the elastic member 330.

[0058] Reference Figure 3 A detection unit 420 is provided at the bottom of the conveying unit 400 for detecting whether a pore sleeve is discharged from the conveying passage 410. Examples of the detection unit 420 include a photoelectric sensor, a magnetic field sensor, and the like.

[0059] The feeding device 10 preferably further includes an air blowing portion 500 . Figure 1 and 2 The air blowing part 500 is clearly shown in the figure, which is connected to the conveying part 400 and provides compressed gas to the conveying channel 410 in the conveying part 400 to help convey the parts in the conveying channel 410. In a preferred embodiment, the air blowing part 500 is a connecting pipe, which is connected to an external compressed air source. The direction of the outlet of the air blowing part 500 is at an angle of less than or equal to 90° with the conveying direction of the parts, or the extension direction of the conveying channel 410, preferably at an angle of 45 to 80°, and more preferably at an angle of 30 to 60°. As a result, the airflow blown out from the air blowing part 500 can push the parts in the conveying channel 410, thereby facilitating the conveying of the parts. It is also possible not to set the air blowing part 500, but to use the gravity of the parts themselves to complete the conveying of the parts in the conveying channel 410.

[0060] The following will refer to Figures 4A to 4D The operating principle of the feeding device 10 of the present invention is described below. Here, the feeding device 10 of the present invention is described by taking the conveying of air hole sleeves as an example. As mentioned above, the feeding device 10 of the present invention is also suitable for conveying other types of parts.

[0061] First, the feeding device 10 is in Figure 4AThe initial state shown. The limiting member 310 completely withdraws from the conveying channel 410, while the blocking member 210 extends into the conveying channel 410, at least partially, preferably completely blocking the conveying channel 410 as shown in the figure. At this time, the first pore sleeve 20-1 and the second pore sleeve 20-2 enter the conveying channel 410 from the upper entrance of the conveying channel 410 and are blocked at the position where the blocking member 210 is located. At this time, as shown in the figure, the first pore sleeve 20-1 is located in the space between the blocking member 210 and the limiting member 310, and at least a part of the second pore sleeve 20-2 is located in the space above the limiting member 310.

[0062] Then, the driving unit 100 starts to work, and drives the blocking member 210 to move in the direction of exiting the conveying passage 410 and drives the limiting member 310 to move in the direction of entering the conveying passage 410. Figure 4B In the state shown, the blocking member 210 has not yet exited or has not yet completely exited the delivery channel 410, thereby continuing to block the first pore sleeve 20-1. The limiting member 310 enters the delivery channel 410 and abuts against the second pore sleeve 20-2.

[0063] The driving unit 100 continues to move, causing the feeding device 10 to enter Figure 4C The state shown. At this time, the blocking member 210 has completely withdrawn from the conveying channel 410, thereby allowing the first pore sleeve 20-1 to fall. The limiting member 310 abuts against the second pore sleeve 20-2, so it no longer moves into the conveying channel 410. At this time, the driving part 100 acts to make the elastic member 330 continue to compress, thereby providing a clamping force to clamp the second pore sleeve 20-2 on the inner wall of the conveying channel 410, so as to avoid squeezing the pore sleeve.

[0064] When the detection unit 420 located below the delivery channel 410 detects that the first pore sleeve 20-1 Figure 4C After being discharged from the conveying passage 410 as shown in FIG, the driving unit 100 reverses and causes the blocking member 210 to enter the conveying passage 410 again, and then the limiting member 310 withdraws from the conveying passage 410 again. In this way, the limiting member 310 releases the clamping of the second pore sleeve 20-2, so that the second pore sleeve 20-2 moves downward into the space between the blocking member 210 and the limiting member 310, and the pore sleeve located upstream of the second pore sleeve 20-2 can move to the space on the right side of the limiting end 312. At this time, since the blocking member 210 has entered the conveying passage 410, the blocking member 210 is prevented from continuing to be conveyed downward, thereby preventing the pore sleeve from slipping.

[0065] As described above, the feeding device 10 of the present invention can realize intermittent delivery of parts such as air hole sleeves and can effectively control the number of parts discharged each time.

[0066] The above describes the preferred embodiment of the feeding device 10 of the present invention. Those skilled in the art can make various modifications and variations to the present invention on this basis.

[0067] For example, the intermediate transition parts between the driving part 100 and the blocking part 200 and between the driving part 100 and the limiting part 300 are respectively referred to as the blocking part push rod 220 and the limiting part push rod 320, but this does not mean that the shape or specific structure of the parts is limited. The blocking part push rod 220 and the limiting part push rod 320 can be any suitable shape, such as shown in the figure, which can be plate-shaped or rod-shaped, etc., as long as they can play the role of power transmission.

[0068] For another example, in the specific structure described above, a driving cylinder that drives the blocking portion 200 and the limiting portion 300 simultaneously is used as a specific implementation of the driving portion 100. However, it is known that the driving portion 100 may also take other forms, such as an electric motor, a hydraulic motor, etc. In addition, there may be two driving components that drive the blocking portion 200 and the limiting portion 300 respectively, and the two driving components are linked to each other to simultaneously make the blocking member 210 and the limiting member 310 enter and exit the conveying channel 410 respectively.

[0069] Further, in the structure shown in the figure, the blocking member 210 and the limiting member 310 are respectively located on both sides of the conveying portion 400. However, the blocking member 210 and the limiting member 310 may also be arranged on the same side of the conveying portion 400, which is also within the scope of the present invention, especially when two driving components are provided to drive the blocking member 200 and the limiting member 300 in linkage, which is achievable.

[0070] Furthermore, the feeding device 10 described above is used in a pore sleeve inlay device as an example, but the feeding device 10 of the present invention can also be used to distribute other types of parts. Further, in the above embodiment described by taking the pore sleeve as an example, according to the requirements of the pore sleeve inlay operation, the device is configured to deliver one pore sleeve at a time. In other application scenarios, the number of parts delivered each time can be set according to the needs of the actual operation, such as one, two or more. This can be achieved by, for example, adjusting the distance between the blocking member 210 and the limiting member 310, the size of the delivery channel 410, etc.
