Description

Technical Field

[0001] The present application relates to the technical field of material conveying, and in particular to a material conveying device. Background Art

[0002] In the production process, a material conveying device equipped with a vibrating feeder is sometimes used to convey materials. For example, the material can be conveyed from the vibrating plate to a fixed material receiving seat, and then the material can be taken away from the material receiving seat. For another example, the material can be conveyed from the vibrating plate to a straight vibration feeder, and then the straight vibration feeder can convey the material to the fixed material receiving seat, and then the material can be taken away from the material receiving seat.

[0003] Since the vibration parameters of the first vibrating feeder are inconsistent with the vibration parameters of the material receiver connected thereto (for example, the material receiver is the second vibrating feeder or the material receiving seat), it is necessary to set a spacing area between the discharge port of the first vibrating feeder and the receiving port of the material receiver to isolate the two and prevent mutual interference between the two.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0034] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0035] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0036] The present application embodiment provides a material conveying device. Figures 1 to 10 The material conveying device 100 provided in the embodiment of the present application includes: a first vibrating feeder 110 , a material receiver 120 and a connecting piece 130 .

[0037] Exemplarily, the first vibrating feeder 110 is a vibrating plate, and the material receiver 120 is a second vibrating feeder or a material receiving seat. For example, the second vibrating feeder is a straight vibrating feeder.

[0038] It should be noted that the vibration plate is an auxiliary feeding device for automatic assembly or automatic processing machinery. There is a pulse electromagnet under the vibration plate hopper, which can make the hopper vibrate in the vertical direction, and the inclined spring sheet drives the hopper to do torsional vibration around its vertical axis. The parts in the hopper rise along the spiral track due to this vibration. During the rising process, after a series of track screening or posture changes, the parts can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing. The direct vibration feeder is also called a linear vibration feeder. The direct vibration feeder is a mechanical device that can convey the material conveyed by the vibration plate in a straight line.

[0039] It should also be noted that, since the vibration plate and the direct vibration feeder are prior art, their structures and working principles will not be described in detail here. It should also be noted that, in other embodiments, the first vibration feeder 110 and the material receiver 120 may also be other devices, as long as they can transport materials.

[0040] Specifically, in the embodiment of the present application, the first vibrating feeder 110 is provided with a discharge trough 111. The material receiver 120 is provided with a receiving trough 121. The receiving trough 121 is docked with the discharge trough 111, and a spacing area 140 is provided between the receiving trough 121 and the discharge trough 111. In this way, when the vibration parameters of the first vibrating feeder 110 and the vibration parameters of the material receiver 120 docked therewith are inconsistent, the spacing area 140 can be provided between the two to avoid direct connection and mutual interference.

[0041] Further, one end of the connecting piece 130 is connected to the discharge trough 111, and the connecting piece 130 spans the spacing area 140 and extends to the receiving trough 121. When the first vibrating feeder 110 is in a vibrating feeding state, the connecting piece 130 can move relative to the receiving trough 121. Exemplarily, the connecting piece 130 is spaced or in contact with the receiving trough 121 so that the connecting piece 130 and the receiving trough 121 are in a non-connected state, thereby preventing the movement parameters of one end of the connecting piece 130 connected to the discharge trough 111 and the other end connected to the receiving trough 121 from being inconsistent, which makes the connecting piece 130 easily damaged.

[0042] In the embodiment of the present application, the groove wall of the discharge groove 111, the connecting piece 130 and the groove wall of the receiving groove 121 form a material conveying channel 150. Figure 2 Thus, the material 200 can be smoothly transported from the entrance of the discharge trough 111 to the receiving trough 121 through the conveying channel 150.

[0043] In this way, in the embodiment provided in the embodiment of the present application, the first vibrating feeder 110 is provided with a discharge trough 111, the material receiver 120 is provided with a receiving trough 121, and a spacing area 140 is provided between the receiving trough 121 and the discharge trough 111. A connecting piece 130 can be provided at a location between the receiving trough 121 and the discharge trough 111 where material jamming is likely to occur as required. For example, if the spacing area between the bottom of the receiving trough 121 and the bottom of the discharge trough 111 is prone to material jamming, a connecting piece 130 connected to the bottom of the receiving trough 121, spanning the bottom spacing area between the bottom of the receiving trough 121 and the bottom of the discharge trough 111, and extending to the bottom of the discharge trough 111 can be provided. For another example, if the material 200 is easily stuck in the spaced area between the side wall of the receiving trough 121 and the side wall of the discharging trough 111, a connecting piece 130 connected to the side wall of the receiving trough 121, spanning the side spaced area between the side wall of the receiving trough 121 and the side wall of the discharging trough 111, and extending to the side wall of the discharging trough 111 can be provided. Thus, in the process of moving from the receiving trough 121 to the discharging trough 111, the connecting piece 130 can be separated between the material 200 and the spaced area 140 to prevent the material 200 from being stuck in the spaced area 140 between the receiving trough 121 and the discharging trough 111.

[0044] In order to facilitate those skilled in the art to better understand the solutions provided by the embodiments of the present application, more detailed examples are provided below for reference by those skilled in the art.

[0045] refer to Figure 4 and Figure 5In some embodiments, the surface of the connecting piece 130 facing the feeding channel 150 is the first outer surface 131. The discharge trough 111 is provided with a second outer surface 1111, wherein the second outer surface 1111 faces the feeding channel 150 and has the same orientation as the first outer surface 131. The first outer surface 131 is flush with the second outer surface 1111. In this way, it is easier for the material 200 to move from the discharge trough 111 to the connecting piece 130.

[0046] Furthermore, the receiving trough 121 is provided with a third outer surface 1211, wherein the third outer surface 1211 faces the feeding channel 150 and has the same orientation as the first outer surface 131. The third outer surface 1211 is flush with the first outer surface 131. In this way, it is easier for the material 200 to move from the connecting piece 130 to the receiving trough 121.

[0047] It should be noted that, illustratively, for some materials 200 of special shapes, the materials 200 may be easily stuck in the bottom spacing area between the bottom of the discharge trough 111 and the bottom of the receiving trough 121. Correspondingly, the bottom of the discharge trough 111 and the bottom of the receiving trough 121 can be connected by the connecting piece 130, and the top surface of the connecting piece 130 is flush with the top surface of the bottom of the discharge trough 111, and the top surface of the connecting piece 130 is also flush with the top surface of the bottom of the receiving trough 121.

[0048] For example, for other materials 200 with special shapes, the materials 200 may be easily stuck in the side spacing area between the side wall of the discharge trough 111 and the side wall of the receiving trough 121. Correspondingly, the side wall of the discharge trough 111 and the side wall of the receiving trough 121 can be connected by the connecting piece 130, and the side of the connecting piece 130 is flush with the side of the discharge trough 111, and the side of the connecting piece 130 is also flush with the side of the receiving trough 121.

[0049] For example, for materials 200 with other special shapes, the materials 200 may be easily stuck in the bottom spacing area between the bottom of the discharge trough 111 and the bottom of the receiving trough 121, and the side spacing area between the side wall of the discharge trough 111 and the side wall of the receiving trough 121. Correspondingly, connecting pieces 130 that connect the bottom and sides of the connecting trough 121 can be respectively arranged at the bottom and sides of the discharge trough 111, so that the top surface of the connecting piece 130 arranged at the bottom of the discharge trough 111 is flush with the top surface of the bottom of the discharge trough 111, and the top surface of the connecting piece 130 arranged at the bottom of the discharge trough 111 is also flush with the top surface of the bottom of the connecting trough 121, and the side surface of the connecting piece 130 arranged at the side of the discharge trough 111 is flush with the side surface of the discharge trough 111, and the side surface of the connecting piece 130 arranged at the side of the discharge trough 111 is also flush with the side surface of the connecting trough 121.

[0050] It should also be noted that the number and shape of the connecting pieces 130 can be flexibly set according to actual needs, as long as the connecting pieces 130 can be separated between the material 200 and the area of ​​the spacing area 140 where material jamming is likely to occur during the process of moving from the receiving trough 121 to the discharging trough 111.

[0051] refer to Figure 5 In some embodiments, the connecting piece 130 includes a connecting end 132 and a suspended end 133 that are separated from each other. The connecting end 132 is connected to the discharge slot 111, and the suspended end 133 extends to the receiving slot 121, and the suspended end 133 is spaced apart from or in contact with the receiving slot 121.

[0052] Exemplarily, the discharge trough 111 is provided with a first step surface, and the connecting end 132 is embedded in the first step surface so that the second outer surface 1111 of the discharge trough 111 is flush with the first outer surface 131 of the connecting piece 130. Exemplarily, the connecting end 132 can be bonded to the discharge trough 111 or welded to the discharge trough 111; the embodiment of the present application does not limit the connection method between the connecting end 132 and the discharge trough 111, and it is only necessary to make the connecting end 132 and the discharge trough 111 be connected to each other. In addition, by adopting a scheme in which the suspended end 133 is spaced apart or in contact with the receiving trough 121, the suspended end 133 of the connecting piece 130 can be in a non-connected state with the receiving trough 121, thereby preventing the movement parameters of the end of the connecting piece 130 connected to the discharge trough 111 and the end connected to the receiving trough 121 from being inconsistent, which makes the connecting piece 130 easy to be damaged.

[0053] Further, refer to Figure 4 and Figure 5 In some embodiments, the connecting piece 130 further includes a first section 134, a second section 135, and a third section 136. The connecting end 132, the first section 134, the second section 135, the third section 136, and the suspended end 133 are sequentially connected along the direction from the discharge trough 111 to the receiving trough 121. A first avoidance portion 1112 that is recessed in a direction away from the first section 134 is provided at a portion of the discharge trough 111 that is opposite to the first section 134. The first avoidance portion 1112 is spaced apart from the first section 134, and the second section 135 is opposite to the spacing area 140. In this way, the first section 134 can be placed in a "suspended" state by spacing apart from the first avoidance portion 1112, so as to increase the deformable amplitude of the connecting piece 130, so that the connecting piece 130 can better connect the discharge trough 111 and the receiving trough 121. The second section 135 may be opposite to the spacer 140 so that the connecting piece 130 is separated between the material 200 and the spacer 140 to prevent the material 200 from being stuck in the spacer 140 between the receiving trough 121 and the discharging trough 111 .

[0054] Furthermore, in some embodiments, a portion of the receiving trough 121 opposite to the third section 136 is provided with a second avoidance portion 1212 that is recessed in a direction away from the third section 136, and the second avoidance portion 1212 is spaced apart from the third section 136. In this way, the third section 136 can be in a "suspended" state by spacing apart from the second avoidance portion 1212, so as to increase the deformable amplitude of the connecting piece 130, so that the connecting piece 130 can better connect the discharging trough 111 and the receiving trough 121.

[0055] In some embodiments, the connecting piece 130 is an elastic piece. For example, the connecting piece 130 is a metal elastic piece or a plastic elastic piece. Of course, in some cases, if the vibration parameters between the first vibrating feeder 110 and the material receiver 120 are not much different, the connecting piece 130 can be made of ordinary materials.

[0056] refer to Figures 6 to 10 In some embodiments, the material discharging trough 111 and the material receiving trough 121 are both U-shaped troughs. The material discharging trough 111 is provided with a first trough bottom surface 111a, a first trough side surface 111b and a second trough side surface 111c, and the first trough side surface 111b and the second trough side surface 111c are opposite to each other. The material receiving trough 121 is provided with a second trough bottom surface 121a, a third trough side surface 121b and a fourth trough side surface 121c, and the third trough side surface 121b and the fourth trough side surface 121c are opposite to each other. There are three connecting pieces 130, and each connecting piece 130 extends from the first trough bottom surface 111a, the first trough side surface 111b and the second trough side surface 111c to the second trough bottom surface 121a, the third trough side surface 121b and the fourth trough side surface 121c respectively.

[0057] For example, reference Figure 8 and Fig.10 The three connecting pieces 130 are respectively a first connecting piece 130a, a second connecting piece 130b and a third connecting piece 130c. Fig. 9 The first connecting piece 130a extends from the first groove bottom surface 111a to the second groove bottom surface 121a. The second connecting piece 130b extends from the first groove side surface 111b to the third groove side surface 121b. The third connecting piece 130c extends from the second groove side surface 111c to the fourth groove side surface 121c.

[0058] In addition, illustratively, when both the discharge trough 111 and the receiving trough 121 are U-shaped troughs, a connecting piece with a U-shaped cross section may be provided accordingly. In addition, illustratively, when both the discharge trough 111 and the receiving trough 121 are V-shaped troughs, a connecting piece with a V-shaped cross section may be provided accordingly, which are not listed one by one here.

[0059] refer to Figure 1 and Figure 2In some embodiments, the first vibrating feeder 110 is a vibrating plate, and the material receiver 120 is a straight vibrating feeder. Figure 3 In some embodiments, the material conveying device 100 further includes a material receiving seat 160, and the material receiving seat 160 is provided with a material receiving port 161 that is connected to the side of the material receiving trough 121 away from the material discharging trough 111. The material 200 can be conveyed to the material receiving port 161 of the material receiving seat 160 by a direct vibration feeder, and then the material 200 can be taken away by an operator, a robot or other material taking device.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0061] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
