Description

Technical Field

[0001] This utility model belongs to the field of slaughtering equipment technology, and in particular relates to a product packing clamp. Background Technology

[0002] As is well known, existing drop-packing technology involves transferring products to a drop baffle above the carton using a conveyor or push-pull device; when the drop baffle opens, the product falls freely into the carton. Traditional baffle opening methods are numerous, categorized into hinged opening and push-pull opening types.

[0003] However, during the product drop process, the synchronization of the baffle opening process is limited. For example, when the drop baffles open asynchronously, the falling product will change its posture during the drop, resulting in the packaging not meeting the requirements. In addition, during the process of conveying the product to the drop baffle, the product moves relative to the baffle or other conveying carriers, which poses a risk of damage to the product packaging bag. Taking frozen product packaging in the slaughtering industry as an example, the inner packaging bag is usually thin, and this process is prone to wear and tear on the inner packaging bag, thus bringing food safety risks. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a product packing fixture, which solves the above problems.

[0005] To achieve the above objectives, this utility model provides a product packing fixture, comprising:

[0006] A frame, wherein a gripper mechanism for holding products and a support claw mechanism for lifting products are respectively provided on the frame;

[0007] A gripper mechanism includes grippers, a gripper opening and closing device, and a gripper slide. The grippers are connected to both sides of the gripper opening and closing device, and the grippers are slidably mounted on the gripper slide.

[0008] The claw mechanism includes a claw opening and closing device, a claw slide, a linkage mechanism, a claw drive plate, and a claw. The claw opening and closing device is connected to the claw drive plate on both sides. The claw drive plate is mounted on the claw slide. One end of the linkage mechanism is connected to the claw drive plate, and the other end is connected to the claw. The linkage mechanism is rotatably connected to the gripper.

[0009] When the gripper opening and closing device is working, it drives the gripper to close, and then drives the support claw to close simultaneously through the linkage mechanism.

[0010] Compared with the prior art, this application has the following advantages: When in use, the gripper opening and closing device drives the gripper to close, so that the gripper holds the product; at the same time, when the gripper closes, the linkage mechanism will drive the support claw to close, so that the support claw enters the bottom of the product to support the product; when the clamp moves to the top of the box under the action of external driving force, the gripper does not move, keeping the product clamped on both sides to ensure the stability of the product posture, and the support claw opening and closing device drives the support claw to open, so that the product falls into the box under the action of gravity.

[0011] Therefore, this application achieves synchronous action of the gripper and the support claw when closing through the design of the linkage mechanism, which solves the problem of asynchronous drop baffle in the prior art. When the gripper and the support claw act on the object being packaged at the same time, the product position is guaranteed, while the force exerted on the product by clamping alone is reduced. This is suitable for situations where the clamping force should not be too large, and avoids damage to the packaging bag caused by excessive clamping force.

[0012] In summary, the packing fixture provided in this application has the following characteristics: it can solve the problem of friction during the product movement to the drop baffle, preventing the inner packaging bag from being worn during product transportation, and it can also solve the problem of asynchrony that is easy to occur during the opening of the drop baffle, preventing the product from changing its posture when falling into the box.

[0013] Furthermore, the claw and the gripper are designed to correspond to each other so that when the claw is closed, the claw can bypass the gripper and support the bottom of the product.

[0014] Furthermore, the claw opening and closing device and the gripper opening and closing device respectively include a claw cylinder and a gripper cylinder. The claw driving plate is connected to both sides of the claw cylinder. The claw driving plate is mounted on the claw slide rail via a claw slider. The gripper cylinder is connected to both sides of the gripper. The gripper is mounted on the gripper slide rail via a gripper slider.

[0015] Furthermore, the linkage mechanism includes a connecting rod, a rotating shaft, a pivot shaft, and a lever arm. One end of the connecting rod is rotatably connected to the claw drive plate, and the other end is rotatably connected to the rotating shaft. One end of the lever arm is rotatably connected to the rotating shaft, and the other end is rotatably connected to the claw. The lever arm is rotatably connected to the gripper through the pivot shaft, so that when the gripper is closed, the claw is driven to close through the pivot shaft.

[0016] Furthermore, it also includes a guide mechanism to guide the product into the box along a predetermined track during the drop process.

[0017] Furthermore, the guiding mechanism includes a guide cylinder and a guide plate. The gripper is provided with a slot, and the guide plate is slidably fitted into the slot so that when the guide cylinder extends or retracts, the guide plate is driven to move along the slot.

[0018] Furthermore, the frame is also equipped with a rotary cylinder for driving the frame to rotate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-3 As shown, this utility model discloses a product packing fixture, comprising:

[0027] The frame 1 is equipped with a gripper mechanism for holding products and a support claw mechanism for lifting products.

[0028] The gripper mechanism includes a gripper 2, a gripper opening and closing device 3, and a gripper slide 4. The gripper 2 is connected to both sides of the gripper opening and closing device 3, and the gripper 2 is slidably mounted on the gripper slide 4.

[0029] The claw mechanism includes a claw opening and closing device 6, a claw slide 7, a linkage mechanism 8, a claw drive plate 9, and a claw 10. The claw opening and closing device 6 is connected to the claw drive plate 9 on both sides. The claw drive plate 9 is installed on the claw slide 7. One end of the linkage mechanism 8 is connected to the claw drive plate 9, and the other end is connected to the claw 10. The linkage mechanism 8 is rotatably connected to the gripper 2.

[0030] When the gripper opening and closing device 3 is working, it drives the gripper 2 to close, and then drives the support claw 10 to close simultaneously through the linkage mechanism 8.

[0031] Compared with the prior art, this application has the following advantages: When in use, the gripper opening and closing device 3 drives the gripper 2 to close, so that the gripper 2 holds the product; at the same time, when the gripper 2 closes, the linkage mechanism 8 will drive the support claw 10 to close, so that the support claw 10 enters the bottom of the product to support the product; when the clamp moves to the top of the box under the action of external driving force, the gripper 2 does not move, keeping the product clamped on both sides to ensure the stability of the product posture, and the support claw opening and closing device 6 drives the support claw 10 to open, so that the product falls into the box under the action of gravity.

[0032] Therefore, this application achieves synchronous action of the gripper 2 and the support claw 10 when closing by designing the linkage mechanism 8, which solves the problem of asynchronous drop baffles in the prior art. When the gripper 2 and the support claw 10 act on the object being packaged at the same time, the product position is guaranteed, while the force exerted on the product by clamping alone is reduced. This is suitable for situations where the clamping force should not be too large, and avoids damage to the packaging bag caused by excessive clamping force.

[0033] In summary, the packing fixture provided in this application has the following characteristics: it can solve the problem of friction during the product movement to the drop baffle, preventing the inner packaging bag from being worn during product transportation, and it can also solve the problem of asynchrony that is easy to occur during the opening of the drop baffle, preventing the product from changing its posture when falling into the box.

[0034] Following the above embodiment, more specifically, the claw 10 and the gripper 2 are designed to correspond so that when the claw 10 is closed, it can bypass the gripper 2 and support the bottom of the product. Wherein, as Figure 1 The image shows the closed state of the gripper 2. When the clamp is set vertically, the gripper 2 holds the product horizontally from both sides, and the support claw 2 supports the product horizontally from the bottom. In this way, the gripper 2 does not need to output too much clamping force, but only needs to maintain the product's posture in the horizontal direction. The product is supported by the support claw 10, thereby completing the clamp's gripping of the product.

[0035] Following the above embodiments, more specifically, the claw opening and closing device 6 and the gripper opening and closing device 3 respectively include a claw cylinder and a gripper cylinder. Claw drive plates 9 are connected to both sides of the claw cylinder, and the claw drive plates 9 are mounted on the claw slide rail 7 via claw sliders 11. Grippers 2 are connected to both sides of the gripper cylinder, and the grippers 2 are mounted on the gripper slide rail 4 via gripper sliders 5. The claw opening and closing device 6 and the gripper opening and closing device 3 can also be hydraulic clamping structures, etc. Any structure capable of driving the grippers 2 or claws 10 to open and close is within the scope of protection of this application.

[0036] Following the above embodiment, more specifically, the linkage mechanism 8 includes a connecting rod 82, a rotating shaft 83, a pivot shaft 84, and a lever arm 81. One end of the connecting rod 82 is rotatably connected to the claw drive plate 9, and the other end is rotatably connected to the rotating shaft 83. One end of the lever arm 81 is rotatably connected to the rotating shaft 83, and the other end is rotatably connected to the claw 10. The lever arm 81 is rotatably connected to the gripper 2 via the pivot shaft 84, so that when the gripper 2 closes, the pivot shaft 84 drives the claw 10 to close. Through the design of the linkage mechanism 8, when the gripper 2 closes, the claw 10 is simultaneously controlled to close, allowing both the gripper 2 and the claw 10 to act on the product simultaneously. This not only maintains the product's posture but also prevents the gripper 2 from providing excessive clamping force, thus preventing damage to the packaging bag during clamping.

[0037] Following the above embodiments, more specifically, it also includes a guide mechanism for guiding the product into the box along a predetermined track during the drop process, so as to prevent the product's posture from changing during the drop.

[0038] Following the above embodiment, more specifically, the guiding mechanism includes a guide cylinder 12 and a guide plate 13. A clamping slot 14 is provided on the gripper 2, and the guide plate 13 is slidably fitted into the clamping slot 14 so that when the guide cylinder 12 extends or retracts, it drives the guide plate 13 to move along the clamping slot 14. Specifically, when the clamp moves above the box, the guide cylinder 12 extends, driving the guide plate 13 to extend into the box, thereby guiding the product to fall into the box along a predetermined track.

[0039] Following the above embodiment, more specifically, the frame 1 is also equipped with a rotary cylinder 15 for driving the frame 1 to rotate. The rotary cylinder 15 can drive the frame 1 to rotate, thereby driving the product to rotate to meet the product orientation requirements during packaging.

[0040] The workflow for this application is as follows:

[0041] 1. Fetching process

[0042] First, both the gripping cylinder and the clamping cylinder remain open, at which point gripper 2 and the supporting claw 10 open simultaneously. Then, the packing fixture is moved above the product, and the gripping cylinder retracts, at which point gripper 2 and the supporting claw 10 close simultaneously. It should be noted that gripper 2 is used to adjust the product's position and posture, making the product's initial posture during the drop packing process more suitable for packing. The supporting claw 10 is located below the product; as the packing fixture moves upward, the supporting claw 10 lifts the product, minimizing the clamping force of gripper 2 on the product.

[0043] 2. Material feeding process

[0044] When the packing fixture moves above the carton to be packed, firstly, the guide cylinder 12 extends, and the guide cylinder 12 drives the guide plate 13 to move down and into the carton. Then, under the guidance of the gripper 2 and the guide plate 13, the product is ensured to be packed into the carton along the predetermined track during the drop process, reducing the risk of packing failure. Then, the gripper cylinder does not move, and the support claw cylinder retracts. At this time, only the support claw 10 performs the opening action, and the product is loaded into the carton by free fall.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
