Detailed Implementation

[0014] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0015] Example 1: An automatic feeding mechanism for strip workpieces, used for feeding at least two strip workpieces 100, includes: at least two feeding units corresponding to the strip workpieces 100, the feeding units are inclined such that their front ends are lower than their rear ends, the at least two feeding units are spaced apart in the vertical direction, and in any two adjacent feeding units, the front end of the upper feeding unit is located in front of the front end of the lower feeding unit, each feeding unit further includes: two inclined guide bars 2, a storage area 3 is formed between the two parallel and spaced guide bars 2, a plurality of strip workpieces 100 can be arranged inclinedly along the length direction of the guide bars 2 in the storage area 3, and the lower surfaces of both ends of each strip workpiece 100 are slidably in contact with the upper surfaces of the two guide bars 2; Each of the two guide bars 2 has a front blocking cylinder 4 and a rear blocking cylinder 5 installed sequentially at its front end and on both sides of the storage area 3. The piston rods of the two front blocking cylinders 4 are set towards the storage area 3 and are equipped with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are set towards the storage area 3 and are equipped with a blocking strip 7. When the piston rod of the front blocking cylinder 4 is in the extended state, the rear surface of the blocking plate 6 is pressed against the front surface of the strip workpiece 100 arranged at the foremost end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from its end into the strip workpiece 100 arranged at the next foremost end. For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in the extended state.

[0016] The above-mentioned feeding unit is provided with 4 units, which are used for feeding 4 strip workpieces 100.

[0017] The four feeding units mentioned above have the same tilt direction but different tilt angles.

[0018] The extension and retraction movements of the front blocking cylinder 4 of each of the above-mentioned feeding units are consistent, and the extension and retraction movements of the rear blocking cylinder 5 of each of the feeding units are consistent.

[0019] The two L-shaped guide bars 2 are arranged opposite each other. The upper surface of the first folded edge 201 of each guide bar 2 is used to contact the lower surface of the strip workpiece 100, and the surface of the second folded edge 202 of the guide bar 2 facing the storage area 3 is used to contact the end face of the strip workpiece 100. The strip-shaped workpieces are placed sequentially from the top of the storage area, so that several strip-shaped workpieces are arranged in an orderly manner in the storage area. Due to the inclined setting of the guide bar, several strip-shaped workpieces in the storage area can slide down along the upper surface of the first folded edge of the guide bar under their own gravity. During this process, the upper parts of both ends of the strip-shaped workpieces are limited by the stop bar to prevent the strip-shaped workpieces from flipping forward and falling down due to the high center of gravity during the descent.

[0020] Each of the above guide strips 2 has a stop strip 11 above its first folded edge 201, and the lower surface of the stop strip 11 is in clearance fit with the end face of the strip-shaped workpiece 100.

[0021] The aforementioned baffle 11 is installed on the second folded edge 202 of the guide strip 2.

[0022] A gasket 9 extending along its length is mounted on the upper surface of the first folded edge 201 of the guide strip 2. The gasket 9 is a Teflon gasket.

[0023] The second folded edge 202 of the guide strip 2 is provided with a clearance through hole 1 for the blocking plate 6 and the blocking strip 7 to pass through.

[0024] One end of the mounting plate 12 is connected to the lower surface of the first folded edge 201 of the guide strip 2, and the other end of the mounting plate 12 extends to the side opposite to the material storage area 3 of the second folded edge 202 of the guide strip 2 and is equipped with the front blocking cylinder 4 and the rear blocking cylinder 5. Each of the front blocking cylinder 4 and the rear blocking cylinder 5 is mounted on the upper surface of the mounting plate 12 through a connecting seat 10, and the blocking plate 6 and the blocking strip 7 are slidably engaged with the corresponding connecting seat 10.

[0025] Example 2: An automatic feeding mechanism for strip workpieces, used for feeding at least two strip workpieces 100, comprising: at least two feeding units corresponding to the strip workpieces 100, wherein the feeding units are inclined such that their front ends are lower than their rear ends, the at least two feeding units are spaced apart in the vertical direction, and in any two adjacent feeding units, the front end of the upper feeding unit is located in front of the front end of the lower feeding unit, each feeding unit further comprising: two inclined guide bars 2, a storage area 3 is formed between the two parallel and spaced guide bars 2, and several strip workpieces 100 can be arranged inclinedly along the length direction of the guide bars 2 in the storage area 3, and the lower surfaces of both ends of each strip workpiece 100 are slidably in contact with the upper surfaces of the two guide bars 2; Each of the two guide bars 2 has a front blocking cylinder 4 and a rear blocking cylinder 5 installed sequentially at its front end and on both sides of the storage area 3. The piston rods of the two front blocking cylinders 4 are set towards the storage area 3 and are equipped with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are set towards the storage area 3 and are equipped with a blocking strip 7. When the piston rod of the front blocking cylinder 4 is in the extended state, the rear surface of the blocking plate 6 is pressed against the front surface of the strip workpiece 100 arranged at the foremost end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from its end into the strip workpiece 100 arranged at the next foremost end. For a number of strip workpieces arranged in the storage area, the strip workpiece located at the bottom and frontmost point stops sliding down under the stop of the stop bar on the front stop cylinder; When the bottommost and frontmost strip workpiece needs to be fed outwards, the piston rod of the rear blocking cylinder is first extended, so that the blocking strips installed on it are embedded into the second to last strip workpiece from both ends, thus stopping the second strip workpiece and the strip workpieces behind it. Then, the piston rod of the front blocking cylinder is retracted, so that the blocking plate removes its obstruction of the bottommost and frontmost strip workpieces, which then slide forward and downward under their own gravity onto the subsequent receiving platform.

[0026] The extension and retraction movements of the front blocking cylinder 4 of each of the above-mentioned feeding units are consistent, and the extension and retraction movements of the rear blocking cylinder 5 of each of the feeding units are consistent.

[0027] At least one sensor 8 is installed on at least one guide bar 2 and at the front end near the storage area 3. The sensing end of the sensor 8 faces the storage area 3 and is used to sense whether there is a strip workpiece 100 in the corresponding storage area 3. Within the storage area, sensors are installed to monitor the sufficiency of materials in real time. When the sensor located below the 6th strip workpiece counting backwards from the front of the storage area fails to detect a workpiece, an alarm is triggered to remind staff to replenish materials in a timely manner, ensuring the continuity and efficiency of processing.

[0028] The aforementioned sensor 8 is a reflective photoelectric sensor, model number Panasonic CX-441.

[0029] The aforementioned sensor 8 is mounted on the lower surface of the guide strip 2 via a connecting piece.

[0030] Two sensors 8 are provided, located directly below the second and sixth strip workpieces 100 counting backwards from the front end of the self-storage area 3.

[0031] The above-mentioned alarm unit is also provided, which is electrically connected to the sensor 8. When the sensor 8 detects that there is no strip workpiece 100 in the corresponding storage area 3, the alarm unit will issue an alarm.

[0032] The working principle of this invention is as follows: For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in the extended state; The strip-shaped workpieces are placed sequentially from the top of the storage area, so that several strip-shaped workpieces are arranged in an orderly manner in the storage area. Due to the inclined setting of the guide bar, several strip-shaped workpieces in the storage area can slide down along the upper surface of the first folded edge of the guide bar under their own gravity. During this process, the upper part of both ends of the strip-shaped workpiece is limited by the stop bar to prevent the strip-shaped workpiece from flipping forward and falling down due to the high center of gravity during the descent. For a number of strip workpieces arranged in the storage area, the strip workpiece located at the bottom and frontmost point stops sliding down under the stop of the stop bar on the front stop cylinder; Within the storage area, sensors are installed to monitor the sufficiency of materials in real time. When the sensor located below the 6th strip workpiece counting backwards from the front of the storage area does not detect any workpiece, an alarm is issued to remind staff to replenish materials in time to ensure the continuity and efficiency of processing. When the bottommost and frontmost strip workpiece needs to be output and fed out, the piston rod of the rear blocking cylinder is first driven to extend, so that the blocking strip installed on it is embedded into the second to last strip workpiece from both ends, thus stopping the second strip workpiece and the strip workpiece behind it. Then the piston rod of the front blocking cylinder is driven to retract, so that the blocking plate removes its obstruction of the bottommost and frontmost strip workpiece, and it slides forward and downward under its own gravity to the subsequent receiving platform. This process is repeated to achieve automatic feeding of each strip-shaped workpiece.

[0033] For the automatic feeding mechanism for strip workpieces, each feeding unit performs the above operation synchronously, so that the strip workpieces at the bottom and front of each feeding platform slide forward and downward under their own gravity to the subsequent receiving platform, thereby realizing the synchronous feeding of multiple strip workpieces.

[0034] The aforementioned automatic strip workpiece feeding mechanism utilizes the workpiece's own weight to power the orderly arrangement and automatic sliding replenishment of multiple workpieces in each group. Furthermore, the coordinated operation of two blocking cylinders in each feeding unit enables automatic sorting of multiple workpieces in each group, allowing for individual feeding of strip workpieces and simultaneous feeding of multiple groups, thus improving processing efficiency and consistency. Moreover, it not only achieves the orderly arrangement and automatic sliding of multiple strip workpieces but also effectively prevents them from overturning due to instability during movement on an inclined surface, ensuring stability and orderliness during the sequential sliding process. Additionally, it provides timely feedback when there are insufficient workpieces in the storage area, facilitating timely replenishment and ensuring processing continuity and efficiency.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
