Description

Technical Field

[0001] This utility model relates to the field of bead-pinning machine technology, specifically to a vibratory feeder rail for bead-pinning machines with adjustable channel height. Background Technology

[0002] The vibratory feeder of the bead-pinning machine is a key mechanism to ensure the orderly delivery and precise orientation of the beads. In particular, the design of the feed rail that works in conjunction with the discharge port of the vibratory feeder directly affects the efficiency and stability of the delivery.

[0003] In the prior art, a conveyor rail for a vibratory feeder of a bead-pinning machine is known. The upper end of the conveyor rail is connected to the discharge port of the vibratory feeder, and the lower end is connected to the bead-pinning installation station. The bead-pinning output from the vibratory feeder is transported to the bead-pinning installation station through the conveyor rail.

[0004] The applicant has found the following defects in the above-mentioned material conveyor design during production practice:

[0005] (1) In order to prevent the nails from jumping out of the feed rail, the feed rail is usually made of upper and lower rails that are interlocked. However, the spacing between the upper and lower rails is fixed, which has poor compatibility with nails of different heights. It is necessary to replace the feed rail with a spacing between the upper and lower rails that matches the height of the nails, which increases the cost of the equipment.

[0006] (2) The upper and lower ends of the conveying rail are rigidly connected. The vibration generated by the vibrating plate may cause the conveying rail to twist and deform, resulting in poor conveying of the nail beads in the conveying rail. Utility Model Content

[0007] This utility model aims to address the aforementioned shortcomings of the prior art by providing an adjustable channel height vibratory feeder rail for a bead-pinning machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution.

[0009] An adjustable-height vibratory feeder for a bead-pinning machine includes a frame and a feeder rail mounted on the frame. The feeder rail includes an upper feeder rail and a lower feeder rail arranged downwards from left to right. The upper and lower feeder rails are positioned opposite each other to form a channel for conveying beads. Multiple first connecting members are arranged along the length of the feeder rail. The lower section of each first connecting member is fixed to the lower feeder rail. The upper section of each first connecting member has a first guide portion that is movably connected to the upper feeder rail. The upper feeder rail has a first fastener that cooperates with the first guide portion. The first fastener is used to releasably secure the upper feeder rail to the first guide portion. When the first fastener releases the upper feeder rail, the first guide portion, in cooperation with the first fastener, limits the movement direction of the upper feeder rail to opening and closing relative to the lower feeder rail, thereby adjusting the distance between the upper and lower feeder rails.

[0010] As an improvement, the first guide portion is an elongated hole with its length direction perpendicular to the length direction of the upper rail, and the first fastener is a bolt that passes through the first guide portion and is screwed onto the upper rail; when the first fastener is released from tightening the upper rail, the movement direction of the upper rail is limited to the length direction of the elongated hole of the first guide portion by the engagement between the elongated hole of the first fastener and the bolt of the first guide portion.

[0011] As another improvement, there are two first connecting parts, located on the upper and lower sections of the conveyor rail respectively.

[0012] As another improvement, the upper end of the lower rail is provided with a second connector, which has a second guide portion that is movably connected to the frame. The frame is provided with a second fastener that cooperates with the second guide portion. The second fastener is used to releasably fasten the second guide portion to the frame. When the second fastener is released from fastening the second guide portion, the second guide portion, in cooperation with the second fastener, limits the movement direction of the second connector relative to the frame, thereby adjusting the relative position of the upper end of the lower rail on the frame.

[0013] Furthermore, the second guide portion is an elongated hole, and the second fastener is a bolt that passes through the second guide portion and is screwed onto the frame. As the elongated hole of the second guide portion, its length direction is set to be inclined downwards away from the lower material rail, and its included angle with the horizontal direction is 40-50 degrees. When the second fastener is released from tightening the lower material rail, the movement direction of the upper end of the lower material rail is limited to the length direction of the elongated hole of the second guide portion by the cooperation between the elongated hole of the second guide portion and the bolt of the second fastener.

[0014] On the other hand, a crossbeam is also provided above the frame in the left-right direction, and a bridging beam is provided in the same direction at the left end of the crossbeam; the end of the crossbeam has a first step, and a first through hole with an axial verticality is provided on the first step; the end of the bridging beam has a second step that is invertedly engaged with the first step, and a second through hole coaxial with the first through hole is provided on the second step; a first set bolt passes through the second through hole and is screwed into the first through hole; the first set bolt and the second through hole are clearance-fitted; and a second fastener is provided on the bridging beam.

[0015] Preferably, the first through hole has two holes arranged in a left-right row, and the second through hole and the first set bolt also have two holes corresponding to the first through hole.

[0016] As another improvement, a third connector is provided, which is connected to the lower end of the lower material rail. The rear end of the third connector is set as a plane that contacts and slides with the frame surface. The top end of the third connector also has a first inclined wedge surface that is inclined forward and downward. The frame is provided with a positioning block that cooperates with the upper end of the third connector. The lower end of the positioning block has a second inclined wedge surface that forms a surface contact with and slides with the first inclined wedge surface.

[0017] Furthermore, the third connector has a third through hole arranged in the front-to-back direction, and the lower end of the lower rail has a fourth through hole corresponding to the third through hole. A second set bolt with clearance fit is inserted in the fourth through hole. After the second set bolt passes through the fourth through hole, it is screwed into the third through hole. The second set bolt and the fourth through hole have clearance fit.

[0018] Preferably, the third through hole has two holes arranged in a left-right row, and the fourth through hole and the second set bolt also have two holes corresponding to the third through hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The distance between the upper and lower feed rails is adjustable, which has good compatibility for different batches of processing using different height sizes of nail beads. There is no need to replace the feed rails for each batch of processing, which can significantly reduce equipment costs.

[0021] (2) Both ends of the conveying rail are set as flexible connections that allow for small displacement within a range of 1-5mm, which can fully offset the vibration generated by the vibrating plate and effectively prevent the conveying rail from twisting and deforming due to vibration.

[0022] (3) It simplifies the installation and debugging of the material conveying rail.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0037] Please see Figures 1 to 2 As shown, in one embodiment, the adjustable channel height bead-pinning machine vibratory feeder includes a frame 1 and a feed rail 2 mounted on the frame 1. The feed rail 2 includes an upper feed rail 21 and a lower feed rail 22 arranged inclined downwards from left to right. The upper feed rail 21 and the lower feed rail 22 are matched vertically to form a channel for conveying beads. Multiple first connecting members 23 are arranged along the length of the feed rail 2. The lower section of the first connecting member 23 is fixed to the lower feed rail 22. The upper section of the first connecting member 23 is movably connected to the upper feed rail 21. The upper material rail 21 is provided with a first fastener 211 that cooperates with the first guide part 231. The first fastener 211 is used to releasably fasten the upper material rail 21 to the first guide part 231. When the first fastener 211 is released from the fastening of the upper material rail 21, the first guide part 231 and the first fastener 211 cooperate to limit the movement direction of the upper material rail 21 to opening and closing relative to the lower material rail 22, so as to adjust the distance between the upper material rail 21 and the lower material rail 22.

[0038] Combined Figure 3As shown, in the above embodiment, the upper end of the conveyor rail 2 is connected to the outlet of the vibratory feeder 91 (not shown), and the lower end is connected to the bead mounting station 92. The conveyor rail 2 transports the beads output by the vibratory feeder 91 to the bead mounting station 92. Addressing the problem of poor compatibility between the conveyor rail 2 and beads of different heights in the prior art, the above embodiment employs an adjustable spacing structure between the upper rail 21 and the lower rail 22. This provides good compatibility for different batches of processing beads with varying heights, eliminating the need to replace the conveyor rail 2 for each batch and significantly reducing equipment costs.

[0039] Specifically, such as Figure 2 As shown, in the above embodiment, the first guide portion 231 is an elongated hole whose length direction is perpendicular to the length direction of the upper material rail 21, and the first fastener 211 is a bolt that passes through the first guide portion 231 and is screwed onto the upper material rail 21; when the first fastener 211 is released from tightening the upper material rail 21, the movement direction of the upper material rail 21 is limited to the length direction of the elongated hole of the first guide portion 231 by the engagement between the elongated hole of the first fastener 211 and the bolt of the first guide portion 231.

[0040] like Figure 1 and Figure 2 As shown, in a preferred embodiment, there are two first connecting members 23, which are respectively located on the upper and lower sections of the conveying rail 2.

[0041] Considering that the alignment accuracy of the feeding rail 2 and the vibratory feeder 9 needs to be corrected during installation and commissioning, the position of the feeding rail 2 may need to be fine-tuned. Therefore, this utility model proposes another preferred embodiment. For example... Figure 4 As shown, the upper end of the lower material rail 22 is provided with a second connecting member 24. The second connecting member 24 has a second guide portion 241 that is movably connected to the frame 1. The frame 1 is provided with a second fastener 11 that cooperates with the second guide portion 241. The second fastener 11 is used to releasably fasten the second guide portion 241 to the frame 1. When the second fastener 11 is released from fastening the second guide portion 241, the second guide portion 241 is used to limit the movement direction of the second connecting member 24 relative to the frame 1 through the cooperation of the second guide portion 241 and the second fastener 11, so as to adjust the relative position of the upper end of the lower material rail 22 on the frame 1.

[0042] Specifically, such as Figure 4As shown, the second guide portion 241 is an elongated hole, and the second fastener 11 is a bolt that passes through the second guide portion 241 and is screwed onto the frame 1. The elongated hole of the second guide portion 241 is set to be inclined downwards away from the lower material rail 22, and its included angle with the horizontal direction is 40-50 degrees. When the second fastener 11 is released from tightening the lower material rail 22, the movement direction of the upper end of the lower material rail 22 is limited to the length direction of the elongated hole of the second guide portion 241 by the engagement of the elongated hole of the second guide portion 241 and the bolt of the second fastener 11.

[0043] To eliminate the impact of the vibration of the vibratory feeder 91 on the conveyor rail 2, such as Figure 1 and Figure 5 As shown, in another preferred embodiment of the present invention, the following configuration is provided: a crossbeam 12 arranged in the left-right direction is provided above the frame 1, and a bridging beam 13 arranged in the same direction at the left end of the crossbeam 12; the end of the crossbeam 12 has a first step portion 121, and the first step portion 121 has an axially vertical first through hole 122; the end of the bridging beam 13 has a second step portion 131 that is invertedly engaged with the first step portion 121, and the second step portion 131 has a second through hole 132 that is coaxial with the first through hole 122; a first set bolt 133 passes through the second through hole 132; the first set bolt 133 passes through the second through hole 132 and is screwed into the first through hole 122; the first set bolt 133 and the second through hole 132 are in clearance fit; and a second fastener 11 is provided on the bridging beam 13.

[0044] In the above configuration, although the first step portion 121 and the second step portion 131 are vertically fixed relative to each other by the first set bolt 133, the left end of the first step portion 121 and the right end of the second step portion 131 are in clearance fit, and the right end of the first step portion 121 and the left end of the second step portion 131 are also in clearance fit. Furthermore, the first set bolt 133 is in clearance fit within the second through hole 132. The cumulative clearances allow for a slight horizontal displacement of the first step portion 121 relative to the second step portion 131. Therefore, the first step portion 121 and the second step portion 131 effectively form a flexible connection, which in turn allows the upper end of the lower material rail 22 to also form a flexible connection relative to the frame 1. This allows the upper end of the conveyor rail 2 to counteract all or part of the vibration generated by the vibratory feeder 91 within the cumulative range of the aforementioned clearances, effectively preventing the conveyor rail 2 from twisting or deforming due to vibration.

[0045] Better, such as Figure 5As shown, the first through hole 122 has two holes arranged in a left-right row, and the second through hole 132 and the first set bolt 133 also have two holes corresponding to the first through hole 122. It is easy to understand that the two first through holes 122 arranged in a left-right row will further limit the range of small horizontal displacement of the first step portion 121 relative to the second step portion 131, and the first step portion 121 will not have excessive displacement relative to the second step portion 131, thus preventing misalignment between the material conveyor rail 2 and the vibrating plate 91.

[0046] In another preferred embodiment, such as Figures 6 to 8 As shown, a third connecting member 25 is also provided, which is connected to the lower end of the lower material rail 22. The rear end of the third connecting member 25 is configured as a plane that contacts and slides with the surface of the frame 1. The top end of the third connecting member 25 also has a first inclined wedge surface 251 that is inclined forward and downward. The frame 1 is provided with a positioning block 14 that cooperates with the upper end of the third connecting member 25. The lower end of the positioning block 14 has a second inclined wedge surface 141 that forms a surface contact with and slides with the first inclined wedge surface 251. In the aforementioned configuration, when the material rail 2 is subjected to the vibration wave of the vibrating plate 91, since the lower end of the material rail 2 is connected to the bead installation station, the lower end of the lower material rail 22 can only move upward and horizontally. With the cooperation of the first wedge surface 251 and the second wedge surface 141, the upward tendency of the lower end of the lower material rail 22 is suppressed, causing the rear end of the third connecting piece 25 to be pressed against the frame 1. At the same time, the tendency of the lower end of the lower material rail 22 to move horizontally is also suppressed to only a small displacement to the left and right. Obviously, the above process achieves a flexible connection at the lower end of the conveyor rail 2, allowing the lower end of the conveyor rail 2 to offset all or part of the vibration generated by the vibrating plate 91 through a small displacement in the left and right direction, effectively preventing the conveyor rail 2 from twisting and deforming due to vibration.

[0047] To further help the lower end of the conveyor rail 2 counteract the vibration generated by the vibratory feeder 91 through a small displacement, the following settings can be made:

[0048] like Figure 7 and Figure 8 As shown, the third connector 25 has a third through hole 252 arranged in the front-back direction, and the lower end of the lower rail 22 has a fourth through hole 221 corresponding to the third through hole 252. A second set bolt 222 with clearance fit is inserted in the fourth through hole 221. After the second set bolt 222 passes through the fourth through hole 221, it is screwed to the third through hole 252.

[0049] In the above configuration, although the third connecting member 25 and the lower end of the lower material rail 22 are relatively fixed in the horizontal direction by the second set bolt 222, the second set bolt 222 is fitted with a clearance fit in the fourth through hole 221, allowing the third connecting member 25 to have a slight vertical displacement relative to the lower end of the lower material rail 22. Therefore, the third connecting member 25 and the lower end of the lower material rail 22 actually form a flexible connection, allowing the lower end of the conveyor rail 2 to vertically offset all or part of the vibration generated by the vibrating plate 91, further preventing the conveyor rail 2 from twisting and deforming due to vibration.

[0050] Better, such as Figure 7 and Figure 8 As shown, the third through hole 252 has two arranged side by side, and the fourth through hole 221 and the second set bolt 222 also have two corresponding to the third through hole 252. It is easy to understand that the two third through holes 252 arranged side by side will further limit the range of slight vertical displacement of the third connecting member 25 relative to the lower end of the lower rail 22, and the lower end of the lower rail 22 will not have excessive displacement relative to the third connecting member 25, thus preventing misalignment between the conveyor rail 2 and the nail bead installation station.

[0051] It should be noted that when the conveyor rail 2 is subjected to the vibration wave of the vibrating plate 91, the amplitude of the conveyor rail 2 in the above-described embodiments of this utility model is limited. Therefore, the slight displacement of the lower end of the conveyor rail 2 will not exceed the allowable fit tolerance between the conveyor rail 2 and the bead installation station, nor will the slight displacement of the upper end of the conveyor rail 2 exceed the allowable fit tolerance between the conveyor rail 2 and the vibrating plate 91. The conveyor rail 2 can still transport the beads output by the vibrating plate 91 to the bead installation station. In contrast, existing technologies often employ more complex structural designs and require complicated installation and debugging in order to reduce the impact of the vibrating plate on the conveyor rail. This utility model simplifies the installation structure of the conveyor rail, greatly reducing the difficulty of installation and debugging.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
