Description

Technical Field

[0001] This invention belongs to the field of meat processing technology, specifically relating to an automated beef bone sawing device. Background Technology

[0002] Before beef is slaughtered and ready for further cooking or processing, it needs to be cut into pieces. Beef ribs are highly sought after because of their versatility in cooking and the variety of products they can be processed into. However, the bones in beef ribs are quite hard, making them difficult to cut. To ensure the rib pieces are aesthetically pleasing and uniform in quality, businesses typically first cut them lengthwise into strips to guarantee each semi-finished product is neatly shaped. Then, they cut them horizontally around the bone, precisely dividing the ribs into smaller pieces with one or two bones.

[0003] Existing beef rib sawing equipment typically features a longitudinal saw blade or saw arm. The ribs are then cut by manual operation and a conveyor system that pushes and redirects the saw. For example, Chinese invention patent CN111543465A discloses a pig rib cutting device, which includes a working platform, a cutting assembly, a clamping and pushing assembly, and a collecting assembly. The working platform has a through-hole for feeding, with two sets of symmetrically arranged inclined feeding plates. The cutting assembly includes a lifting and tensioning mechanism, a cutting drive mechanism, and a double-sided saw blade. The clamping and pushing assembly includes a horizontal displacement mechanism, a clamping mechanism, and a cutting and pushing mechanism. The clamping mechanism includes clamping plates capable of clamping the bones. In use, the pig rib is placed in the clamping mechanism and clamped. The horizontal displacement mechanism pushes the pig rib into the cutting assembly. The double-sided saw blade cuts the pig rib on both sides as it moves back and forth at the output end of the horizontal displacement mechanism. The cutting and pushing mechanism ensures a consistent width of the cut.

[0004] Although it can cut beef ribs into rib pieces, it requires manual repeated fixing of the ribs to cut the completed ribs longitudinally into multiple semi-finished products. Only after manually reversing the direction of the semi-finished products and repeatedly putting them into the machine for transverse cutting can the completed ribs be cut into pieces. Its automation level is low, which not only makes the operation complicated and the processing efficiency low, but also makes it difficult to ensure the consistency of the rib pieces because the saw blade and the ribs are aligned manually before cutting.

[0005] Therefore, it is necessary to research an automated beef bone sawing device that can automatically position the beef ribs and saw blade and automatically cut the beef ribs into pieces. Summary of the Invention

[0006] In view of the above-mentioned shortcomings in the existing technology, the present invention provides an automated beef bone sawing device to solve the technical problems of low automation of existing bone sawing devices, which not only have low processing efficiency, but also produce beef rib pieces with differences in size and shape.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] An automated beef bone sawing device includes: a frame, a drive mechanism, a positioning module, and a multi-saw blade cutting mechanism;

[0009] The frame is also equipped with a support plate and a conveyor belt. The support plate is located at the front end of the frame, and the conveyor belt is located at the rear end of the frame. The upper end of the support plate and the conveyor belt are at the same height.

[0010] The drive mechanism includes a translation component, a connecting arm, and a reversing component. The translation component is mounted on the frame, and the reversing component is mounted on the translation component via the connecting arm.

[0011] The positioning module includes a bracket, a positioning slider, a spring, a lifting plate, and a lifting cylinder. The bracket is slidably mounted on the reversing assembly, and the positioning slider is slidably mounted on the bracket. The positioning slider also includes a flexible positioning post and a guide rod. A flexible positioning post is provided on the lower end face of the positioning slider, and a guide rod is provided on the upper end face of the positioning slider. The lifting plate is connected to the bracket through the lifting cylinder. A guide hole is also provided on the lifting plate, and the guide rod slides in cooperation with the guide hole. The spring is mounted on the guide rod, with one end connected to the positioning slider and the other end connected to the lifting plate.

[0012] The multi-saw blade cutting mechanism is mounted on the frame, and saw blades are provided on the multi-saw blade cutting mechanism, with the saw blades located between the support plate and the conveyor belt.

[0013] Furthermore, the translation component includes a fixed plate, a horizontal sliding plate, a vertical sliding plate, and a connecting arm. The fixed plate is fixedly connected to the frame, the horizontal sliding plate is slidably mounted on the fixed plate, the vertical sliding plate is slidably mounted on the horizontal sliding plate, and the connecting arm is fixedly connected to the vertical sliding plate.

[0014] Furthermore, the commutation assembly includes a commutation motor and a commutation plate, wherein the commutation motor is fixedly connected to the connecting arm, and the shaft of the commutation motor is fixedly connected to the commutation plate.

[0015] Furthermore, the reversing plate also includes a propulsion groove, a propulsion motor, and a lead screw. The lower end face of the reversing plate is provided with a propulsion groove, the lead screw is rotatably disposed in the propulsion groove, and the shaft of the propulsion motor is fixedly connected to the lead screw.

[0016] Furthermore, the upper surface of the bracket is provided with a push slide rail and a lug. The push slide rail is slidably engaged with the push groove, and the lug is engaged with the lead screw through a thread.

[0017] Furthermore, the lifting plate also includes a sensor bracket and a through-beam sensor. The sensor bracket is fixedly mounted on the upper surface of the lifting plate, and the position of the sensor bracket corresponds to the guide hole. The through-beam sensor is mounted on the sensor bracket.

[0018] Furthermore, multiple sets of through-beam sensors are mounted longitudinally side-by-side on a sensor bracket.

[0019] Furthermore, the positioning module also includes a lifting cylinder and an elastic cloth. The elastic cloth is set at the lower end of the bracket, and the elastic cloth storage machine is fixedly connected to the side of the bracket. One end of the elastic cloth is fixedly connected to the side of the bracket, and the other end is connected to the elastic cloth storage machine.

[0022] 1. The present invention discloses an automated beef bone sawing device, which is equipped with a drive mechanism and a positioning module for driving the movement and reversing of beef ribs. After longitudinally cutting the beef ribs into strip-shaped semi-finished products, it can automatically reverse the direction to perform transverse cutting, cutting the semi-finished products into beef rib pieces.

It has a high degree of automation, not only with high processing efficiency, but also with small differences in the size and shape of the cut beef rib pieces, ensuring the consistency of the finished product.

[0023] 2. The automated beef bone sawing device disclosed in this invention achieves the positioning, movement and reversal of beef ribs through a drive mechanism and positioning module. It can no longer only cut frozen beef ribs, which not only saves freezing costs, but also produces higher quality beef ribs that are more easily accepted by consumers. Attached Figure Description

[0036] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0038] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] Please see Figures 1 to 10 As shown, an automated beef bone sawing device includes: a frame (1) for supporting and conveying beef ribs, a drive mechanism (2) for driving the positioning module (3) to move and change direction, a positioning module (3) for positioning and driving the beef ribs to move, and a multi-saw cutting mechanism (4) for cutting the beef ribs.

[0040] The frame (1) is also provided with a support plate (11) and a conveyor belt (12). The support plate (11) is located at the front end of the frame (1), and the conveyor belt (12) is located at the rear end of the frame (1). The upper ends of the support plate (11) and the conveyor belt (12) are at the same height. It can be understood that the beef ribs placed on the support plate (11) can be moved from the support plate (11) to the conveyor belt (12) under the drive of the drive mechanism (2) and the positioning module (3). The beef ribs after cutting can be moved from the conveyor belt (12) to the support plate (11) under the drive of the conveyor belt (12).

[0041] The drive mechanism (2) includes a translation component, a connecting arm (24) and a reversing component. The translation component is mounted on the frame (1), and the reversing component is mounted on the translation component via the connecting arm (24).

[0042] Specifically, the translation assembly includes a fixed plate (21), a horizontal sliding plate (22), a vertical sliding plate (23), and a connecting arm (24). The fixed plate (21) is fixedly connected to the frame (1), the horizontal sliding plate (22) is slidably disposed on the fixed plate (21), the vertical sliding plate (23) is slidably disposed on the horizontal sliding plate (22), and the connecting arm (24) is fixedly connected to the vertical sliding plate (23). Specifically, the reversing assembly includes a reversing motor (25) and a reversing plate (26), the reversing motor (25) is fixedly connected to the connecting arm (24), and the shaft of the reversing motor (25) is fixedly connected to the reversing plate (26). It can be understood that the horizontal slide (22) can drive the vertical slide (23), connecting arm (24), reversing assembly and positioning module (3) installed on the reversing assembly to move horizontally, the vertical slide (23) can drive the connecting arm (24), reversing assembly and positioning module (3) to move vertically, and the reversing motor (25) can drive the reversing plate (26) and positioning module (3) to rotate to complete the reversing.

[0043] The reversing plate (26) also includes a propulsion groove (261), a propulsion motor (262), and a lead screw (263). The propulsion groove (261) is provided on the lower end surface of the reversing plate (26), the lead screw (263) is rotatably disposed in the propulsion groove (261), and the shaft of the propulsion motor (262) is fixedly connected to the lead screw (263).

[0044] The positioning module (3) includes a bracket (31), a positioning slider (32), a spring (33), a lifting plate (34), and a lifting cylinder (35). The bracket (31) is slidably mounted on the reversing assembly. Correspondingly, the upper surface of the bracket (31) is provided with a push slide rail (311) and a lug (312). The push slide rail (311) is slidably engaged with the push groove (261). The lug (312) is engaged with the lead screw (263) through a thread. It can be understood that the push motor (262) drives the lead screw (263) to rotate forward and backward. Through the engagement of the lead screw (263) and the lug (312), the positioning slider (32) is driven to push out and retract along the push groove (261).

[0045] The positioning slider (32) is slidably mounted on the bracket (31). The positioning slider (32) also includes a flexible positioning post (321) and a guide rod (322). The flexible positioning post (321) is provided on the lower end surface of the positioning slider (32), and the guide rod (322) is provided on the upper end surface of the positioning slider (32). The lifting plate (34) is connected to the bracket (31) through a lifting cylinder (35). The lifting plate (34) is also provided with a guide hole (341). The guide rod (322) is slidably engaged with the guide hole (341). The spring (33) is mounted on the guide rod (322). One end of the spring (33) is connected to the positioning slider (32), and the other end is connected to the lifting plate (34).

[0046] It can be understood that the extension of the lifting cylinder (35) can push the lifting plate (34) and the positioning slider (32) to descend. After the flexible positioning column (321) at the lower end of the positioning slider (32) comes into contact with the beef rib, the beef rib meat is tough and the flexible positioning column (321) can continue to descend the first distance after contact with the beef rib meat. However, the beef rib bone is relatively hard, and the flexible positioning column (321) is blocked after contact with the beef rib bone and cannot continue to descend. During the descent of the lifting plate (34), the spring (33) is compressed and the guide rod (322) slides upward along the guide hole (341). This prevents the lifting plate (34) from blocking the other positioning sliders (32) from descending because the flexible positioning post (321) of some positioning sliders (32) cannot descend due to contact with the bone part. At the same time, the length of the guide rod (322) sliding out of the guide hole (341) will also vary depending on the contact position between the positioning slider (32) and the beef rib, making it easier to determine the position of the bone part in the beef rib. Meanwhile, since some of the flexible positioning posts (321) are pressed into the meat part of the beef rib, the beef rib can be fixed to the support plate (11) or the conveyor belt (12). It can also be moved or rotated by driving the positioning module (3) to realize the movement and reversal of the beef rib.

[0047] Correspondingly, the lifting plate (34) also includes a sensor bracket (342) and a through-beam sensor (343). The sensor bracket (342) is fixedly mounted on the upper surface of the lifting plate (34), and the position of the sensor bracket (342) corresponds to the guide hole (341). The through-beam sensor (343) is mounted on the sensor bracket (342). Correspondingly, the multiple sets of through-beam sensors (343) are mounted longitudinally side by side on the sensor bracket (342). It can be understood that when the guide rod (322) slides out from the guide hole (341) and reaches the through-beam sensor (343), the through-beam sensor (343) can be activated. The multiple sets of through-beam sensors (343) are mounted longitudinally side by side, which facilitates the determination of the difference in the extension length of each guide rod (322).

[0048] The positioning module (3) also includes a lifting cylinder (35) and an elastic cloth (36). The elastic cloth (36) is set at the lower end of the bracket (31). The elastic cloth storage machine (361) is fixedly connected to the side of the bracket (31). One end of the elastic cloth (36) is fixedly connected to the side of the bracket (31), and the other end is connected to the elastic cloth storage machine (361). It can be understood that when the lifting plate (34) pushes the positioning slider (32) down, the elastic cloth storage machine (361) releases part of the elastic cloth (36), which does not hinder the contact between the flexible positioning column (321) and the rib. After the lifting plate (34) drives the positioning slider (32) to rise, the elastic cloth storage machine (361) tightens the elastic cloth (36), so that the elastic cloth (36) at the lower end of the positioning slider (32) is taut. At this time, the rib can slide along the elastic cloth (36) under the drive of the conveyor belt (12).

[0049] The multi-saw blade cutting mechanism (4) is mounted on the frame (1), and a saw blade (41) is provided on the multi-saw blade cutting mechanism (4). The saw blade (41) is located between the support plate (11) and the conveyor belt (12). Correspondingly, the position of the saw blade (41) corresponds to the gap between two adjacent sets of positioning modules (3).

[0050] The working principle of this invention is as follows:

[0051] Place the beef ribs on the support plate (11) and manually start the equipment;

[0052] The translation component drives the positioning module (3) to move horizontally to the back of the saw blade (41), the propulsion motor (262) rotates forward, and the positioning module (3) is driven to extend along the propulsion slide (261) through the lead screw (263). After reaching the top of the rib rack, the translation component drives the reversing component and the positioning module (3) to descend as a whole until the lower end of the positioning module (3) contacts the rib rack.

[0053] The elastic fabric storage machine (361) releases part of the elastic fabric (36), so that the elastic fabric (36) is no longer taut;

[0054] The extension of the lifting cylinder (35) can push the lifting plate (34) and the positioning slider (32) to descend. After the flexible positioning column (321) at the lower end of the positioning slider (32) comes into contact with the beef rib, the beef rib meat is tough and the flexible positioning column (321) can continue to descend for the first distance after contact with the beef rib meat. However, the beef rib bone is harder, and the flexible positioning column (321) is blocked after contact with the beef rib bone and cannot continue to descend. During the descent of the lifting plate (34), the spring (33) is compressed and the guide rod (322) slides upward along the guide hole (341). At the same time, part of the flexible positioning column (321) is pressed into the beef rib meat.

[0055] The propulsion motor (262) reverses and drives the positioning module (3) to retract along the propulsion chute (261) below the reversing plate (26). During the retraction process, the positioning module (3) drives the rib rack from the support plate (11) to the conveyor belt (12) through the flexible positioning column (321) and contacts the saw blade (41) to longitudinally cut the rib rack into strip-shaped semi-finished products.

[0056] The translation component drives the reversing component, the positioning slider (32) and the strip-shaped semi-finished product to move backward a certain distance to prevent the reversing module (3) from contacting the saw blade (41);

[0057] The commutator motor (25) rotates to drive the commutator plate (26), positioning module (3) and the rib rack to rotate 90 degrees as a whole;

[0058] Since the bone portion of the beef ribs is shaped like a house, the bone portions of different strip-shaped semi-finished products are not aligned after cutting. The length of the guide rod (322) sliding out of the guide hole (341) will also vary depending on the contact position between the positioning slider (32) and the beef ribs. The position of the bone portion is determined according to the number of photoelectric sensors (343) triggered by the guide rod (322). The propulsion motor (262) is started, and the corresponding positioning module (3) moves along the propulsion groove (261) to align the bone portions of different strip-shaped semi-finished products.

[0059] The translation component drives the reversing component, positioning slider (32) and the rib rack forward to the saw blade (41);

[0060] The elastic fabric storage machine (361) tightens the elastic fabric (36);

[0061] The conveyor belt (12) is started, pushing the strip-shaped semi-finished product from the conveyor belt (12) to the support plate (11). During this process, the strip-shaped semi-finished product comes into contact with the saw blade (41) to complete the transverse cutting and cut the strip-shaped semi-finished product into rib blocks.
