Description

Technical Field

[0001] This application relates to the field of silos, and in particular to a silo suitable for irregularly shaped materials. Background Technology

[0002] In the assembly line, materials need to be stored in silos. During production, operators store the required materials in batches in the silos to reduce the number of manual loading operations. The materials stored in the silos can then be transferred in batches and accurately to designated workstations for processing or assembly by gantry robots.

[0003] Regarding the aforementioned technologies, for irregularly shaped materials, such as motor housings, the surface has many protrusions and depressions. After operators store irregularly shaped materials in batches in the silo, the materials stored in the silo may become disordered, causing them to deflect while waiting for the gantry robot to grasp them, thus making it difficult for the gantry robot to accurately grasp the irregularly shaped materials. Summary of the Invention

[0004] To reduce the occurrence of deflection of irregularly shaped materials while waiting for the gantry robot to grasp them, this application provides a hopper suitable for irregularly shaped materials.

[0005] The technical solution provided in this application for a silo suitable for irregularly shaped materials is as follows: A hopper suitable for irregularly shaped materials includes a feeding conveyor belt, a contour-following fixed plate, a contour-following movable plate, and a movable plate detector, wherein the feeding conveyor belt is used to place irregularly shaped materials; The contour-following fixing plate is installed on the feeding conveyor belt, and the contour-following fixing plate has a through-hole fixed material trough, the shape of which is adapted to irregularly shaped materials. The contouring movable plate slides and cooperates with the contouring fixed plate along the conveying direction of the feeding conveyor belt. The contouring movable plate is set towards the direction of the irregular material. The contouring movable plate has a through-hole movable material groove. A return spring is installed between the contouring movable plate and the contouring fixed plate. The movable plate detector is used to detect whether the contour movable plate slips along the conveying direction of the feeding conveyor belt. When the movable plate detector detects that the contour movable plate has slipped along the conveying direction of the feeding conveyor belt, the movable plate detector sends a warning signal to the operator.

[0006] By adopting the above technical solution, irregularly shaped materials are placed in batches on the feeding conveyor belt, and then conveyed forward with the feeding conveyor belt. If the posture of the irregularly shaped materials is normal and there is no deflection, the irregularly shaped materials will pass through the movable material trough and the fixed material trough in sequence, and accurately reach the gripping position of the gantry robot.

[0007] If the irregularly shaped material exhibits abnormal posture or deflection, it will be unable to pass through the movable material chute and push the contouring movable plate closer to the contouring fixed plate. The movable plate detector detects slippage of the contouring movable plate along the conveyor belt and sends a warning signal to the operator, allowing for timely correction and reducing the occurrence of irregularly shaped materials deflecting while waiting for the gantry robot to grasp them.

[0008] Optionally, the feeding conveyor belt is slidably fitted with a feeding limit plate along its own width direction, and the feeding limit plate is located at the top of the feeding conveyor belt.

[0009] By adopting the above technical solution, it is easy to adapt to irregularly shaped materials of different specifications by adjusting the position of the feeding limit plate, thereby reducing the occurrence of irregularly shaped materials being difficult to put into the feeding conveyor belt, or irregularly shaped materials being unstable along the feeding conveyor belt.

[0010] Optionally, the feeding limit plate is provided with an adjustment keyway extending along the width of the feeding conveyor belt, and the feeding limit plate is installed on the feeding conveyor belt by bolts passing through the adjustment keyway.

[0011] By adopting the above technical solution, the installation position of the feeding limit plate can be quickly adjusted by turning the bolts passing through the adjustment keyway.

[0012] Optionally, the contouring fixed plate is inserted and fitted with a movable plate slide rod, and the contouring movable plate is slidably fitted to the contouring fixed plate via a sliding guide rod, and the sliding guide rod is inserted and fitted to the contouring fixed plate.

[0013] By adopting the above technical solution, it is convenient to disassemble and replace the specifications of the contour-following movable plate according to the type of irregular material.

[0014] Optionally, the contoured fixing plate is threaded with a sliding bolt, which is tightly fitted to the sliding rod of the movable plate.

[0015] By adopting the above technical solution, it is possible to securely install the contouring movable plate onto the contouring fixed plate while ensuring the ease of assembly and disassembly of the contouring movable plate.

[0016] Optionally, the contouring fixed plate is fitted with a material positioning rod, and the material positioning rod and the contouring movable plate are located on both sides of the contouring fixed plate.

[0017] By adopting the above technical solution, it is convenient to limit the two sides of the irregular material by means of the material positioning rod after the irregular material passes through the movable material trough and the fixed material trough in sequence, so that the irregular material is not easy to deflect while waiting for the gantry robot to grab it.

[0018] Optionally, the contour fixing plate is threaded with a positioning rod bolt, which is tightened against the material positioning rod.

[0019] By adopting the above technical solution, the material positioning rod can be stably installed on the contour fixing plate while ensuring the ease of disassembly and assembly.

[0020] Optionally, the feeding conveyor belt is equipped with a positioning cylinder, and the piston rod of the positioning cylinder is set vertically downward.

[0021] By adopting the above technical solution, after the irregularly shaped material passes through the movable material trough and the fixed material trough in sequence, the positioning cylinder extends the piston rod to press against the irregularly shaped material until the gantry robot approaches, which helps to further reduce the occurrence of the irregularly shaped material deflecting while waiting for the gantry robot to grab it.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After irregularly shaped materials are placed in batches on the feeding conveyor belt, they are conveyed forward along with the feeding conveyor belt. If the posture of the irregularly shaped materials is normal and there is no deflection, the irregularly shaped materials will pass through the movable material trough and the fixed material trough in sequence, and accurately reach the gripping position of the gantry robot. If the irregularly shaped material exhibits abnormal posture or deflection, it will be unable to pass through the movable material chute and push the contouring movable plate closer to the contouring fixed plate. The movable plate detector detects slippage of the contouring movable plate along the conveyor belt and sends a warning signal to the operator, allowing the operator to correct the situation promptly. This reduces the occurrence of irregularly shaped materials deflecting while waiting for the gantry robot to grasp them. 2. It facilitates the adaptation of irregularly shaped materials of different specifications by adjusting the position of the feeding limit plate, reducing the occurrence of irregularly shaped materials being difficult to put into the feeding conveyor belt, or the irregularly shaped materials being unstable along the feeding conveyor belt; 3. After the irregularly shaped material passes through the movable material trough and the fixed material trough in sequence, the positioning cylinder extends the piston rod to press against the irregularly shaped material until the gantry robot approaches. This helps to further reduce the occurrence of the irregularly shaped material deflecting while waiting for the gantry robot to grab it. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example 1: Embodiment 1 of this application discloses a silo suitable for irregularly shaped materials. (Refer to...) Figure 1 The hopper suitable for irregularly shaped materials includes a feeding conveyor belt 1, a contour-following fixed plate 2, a contour-following movable plate 3, and a movable plate detector 4. In this embodiment, the hopper including the feeding conveyor belt 1, the contour-following fixed plate 2, the contour-following movable plate 3, and the movable plate detector 4 is provided in two sets, and the two sets of hoppers are arranged horizontally side by side to improve feeding efficiency.

[0032] The feeding conveyor belt 1 is fixedly installed on the ground by a frame, and is arranged horizontally to facilitate the horizontal conveying of irregularly shaped materials. Furthermore, in this embodiment, the feeding conveyor belt 1 is a type that uses pulleys and a belt for conveying. Figure 2 The top of the feeding conveyor belt 1 is provided with two feeding limit plates 11, which are distributed on both sides of the feeding conveyor belt 1 along the width direction of the feeding conveyor belt 1, and the cross-section of the two feeding limit plates 11 is "L" shaped. The feeding conveyor belt 1 is provided with an adjusting keyway 111, which extends along the width direction of the feeding conveyor belt 1. The feeding limit plates 11 are installed on the feeding conveyor belt 1 by bolts (not shown in the figure) passing through the adjusting keyway 111, so that the feeding limit plates 11 can slide along the width direction of the feeding conveyor by loosening the bolts, thereby enabling the feeding limit plates 11 to limit irregularly shaped materials of different specifications.

[0033] Reference Figure 2 and Figure 3 The contour fixing plate 2 is located at the output end of the feeding conveyor belt 1, and is installed on the frame of the feeding conveyor belt 1 by bolts at the bottom, so as to facilitate disassembly and replacement of the contour fixing plate 2 according to the specifications of the irregularly shaped materials. The contour fixing plate 2 has a through-hole material fixing groove 201, the shape of which is adapted to the irregularly shaped materials. That is, the irregularly shaped materials can only pass through the material fixing groove 201 in a set posture. When the irregularly shaped materials deflect, the protrusions of the irregularly shaped materials collide with the contour fixing plate 2, causing the irregularly shaped materials to be blocked and unable to pass through the material fixing groove 201 and the contour fixing plate 2.

[0034] Reference Figure 2 and Figure 3 The contouring movable plate 3 is located on one side of the contouring fixed plate 2, and is positioned facing the direction from which the irregularly shaped material is coming. The contouring movable plate 3 slides and engages with the contouring fixed plate 2 via two movable plate slide rods 21, and the sliding direction of the contouring movable plate 3 is set along the conveying direction of the feeding conveyor belt 1. A movable material trough 301 is provided through the contouring movable plate 3. The shape of the movable material trough 301 is adapted to the irregularly shaped material; that is, the irregularly shaped material can only pass through the movable material trough 301 in a predetermined posture. When the irregularly shaped material deflects, the protrusion of the irregularly shaped material collides with the contouring movable plate 3, causing the contouring movable plate 3 to slide towards the position of the contouring fixed plate 2.

[0035] A return spring 31 is provided between the contouring movable plate 3 and the contouring fixed plate 2, and the return spring 31 is sleeved on the movable plate slide rod 21 so that after the contouring movable plate 3 slides towards the position of the contouring fixed plate 2, it can be reset by the elastic force of the return spring 31 and the subsequent irregular object can be detected.

[0036] Reference Figure 4 The movable plate slide rod 21 is inserted into the contour fixing plate 2 and is locked by the slide rod bolt 22 threaded into the contour fixing plate 2, so that the movable plate slide rod 21 can be pulled out by loosening the slide rod bolt 22 and the contour movable plate 3 can be quickly replaced.

[0037] Reference Figure 3The movable plate detector 4 is fixedly installed on the feeding conveyor belt 1, with its detection end aligned between the contour movable plate 3 and the contour fixed plate 2. The movable plate detector 4 detects whether the contour movable plate 3 slips along the conveying direction of the feeding conveyor belt 1. When the movable plate detector 4 detects slippage of the contour movable plate 3 along the conveying direction of the feeding conveyor belt 1, it sends a warning signal to the operator. The warning signal can be an image, text, light, and / or sound. For example, the movable plate detector 4 can be a proximity switch electrically connected to a buzzer, which emits an sound to alert the operator to perform detection and screening when the contour movable plate 3 is pushed.

[0038] Reference Figure 2 and Figure 4 The contouring fixed plate 2 is fitted with two material positioning rods 5, both located on the same side of the contouring fixed plate 2, and the two material positioning rods 5 and the contouring movable plate 3 are located on opposite sides of the contouring fixed plate 2. After the irregularly shaped material passes through the movable material trough 301 and the fixed material trough 201 in sequence, the two material positioning rods 5 limit the irregularly shaped material from both horizontal sides, making it less likely for the irregularly shaped material to deflect, thus facilitating accurate gripping by the gantry robot.

[0039] The contour fixing plate 2 has two positioning rod bolts 23 threadedly fitted. The two positioning rod bolts 23 are respectively abutted against each material positioning rod 5, so that when it is necessary to remove or replace the material positioning rod 5, the positioning rod bolts 23 can be loosened.

[0040] Reference Figure 2 A positioning cylinder 6 is fixedly installed on the top of the feeding conveyor belt 1. The positioning cylinder 6 and the contouring movable plate 3 are located on opposite sides of the contouring fixed plate 2, with the piston rod of the positioning cylinder 6 pointing vertically downwards. After the irregularly shaped material passes through the movable material trough 301 and the fixed material trough 201 in sequence, the positioning cylinder 6 extends its piston rod to press against the irregularly shaped material until the gantry robot approaches, thereby reducing the possibility of the irregularly shaped material deflecting while waiting for the gantry robot to grasp it. In addition, a material detector 12 is also fixedly installed on the feeding conveyor belt 1. The material detector 12 is used to detect whether there is irregularly shaped material at the bottom of the positioning cylinder 6. When the material detector 12 detects that there is irregularly shaped material at the bottom of the positioning cylinder 6, the positioning cylinder 6 will extend its piston rod to press against the irregularly shaped material and wait for the gantry robot to approach.

[0041] The implementation principle of a silo suitable for irregularly shaped materials in Embodiment 1 of this application is as follows: After the irregularly shaped materials are placed in batches on the feeding conveyor belt 1, the irregularly shaped materials are conveyed forward with the feeding conveyor belt 1. If the posture of the irregularly shaped materials is not abnormal and there is no deflection, the irregularly shaped materials will pass through the movable material trough 301 and the fixed material trough 201 in sequence, and accurately reach the gripping position of the gantry robot. If the irregularly shaped material exhibits abnormal posture or deflection, it will be unable to pass through the movable material trough 301 and push the contouring movable plate 3 towards the contouring fixed plate 2. The movable plate detector 4 detects that the contouring movable plate 3 has slipped along the conveying direction of the feeding conveyor belt 1, and then sends a warning signal to the operator, allowing the operator to correct the situation in a timely manner. This reduces the occurrence of irregularly shaped materials deflecting while waiting for the gantry robot to grab them.

[0042] Example 2: Embodiment 2 of this application provides a contour-following movable plate, which can be applied to the silo suitable for irregularly shaped materials described in Embodiment 1. (See reference...) Figure 5 In addition to all the technical features of the contouring movable plate 3 described in Embodiment 1, the contouring movable plate also includes the following technical features: The material of the contouring movable plate 3 is plastic, and the corners of the movable material trough 301 are rounded to prevent excessive wear between irregularly shaped materials and the contouring movable plate 3.

[0043] Example 3: Embodiment 3 of this application discloses a silo suitable for irregularly shaped materials, which, in addition to all the technical features of Embodiment 1, also includes the following technical features: Reference Figure 6 The top of the frame is equipped with a transfer assembly 7, which is located between two sets of material bins. The transfer assembly 7 includes a horizontal linear module 71, an electric telescopic rod 72, and a clamping cylinder 73. The horizontal linear module 71 is fixedly installed on the frame and is arranged horizontally. The electric telescopic rod 72 is fixedly installed on the mover of the horizontal linear module 71, and the clamping cylinder 73 is fixedly installed on the vertically arranged mover of the electric telescopic rod 72, so that the clamping cylinder 73 can be adjusted in both the horizontal and vertical directions, thereby facilitating the timely transfer and removal of irregularly shaped materials blocked by the contouring movable plate 3.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
