Technical Field
[0001] This utility model belongs to the field of slaughtering equipment technology, and in particular relates to an automatic unhooking device. Background Technology
[0002] Among pig by-products, pig liver and pig diaphragm are two products with large individual weight and are widely popular. In the slaughtering process, pig liver and pig diaphragm are often hung by hooks to drain and pre-cool. However, in the packaging process, the pig liver or pig diaphragm must be removed from the hanging position before packaging.
[0003] Currently, the market uses manual methods for unloading, which is labor-intensive and inefficient. Furthermore, due to the pre-cooling process, the product temperature is low, and prolonged contact with low-temperature products can easily cause rheumatism and other diseases in the hands. Therefore, developing automatic unhooking equipment to replace manual labor is of great significance. Utility Model Content

Detailed Implementation
[0033] 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.
[0034] like Figure 1 , Figure 9 As shown, this utility model discloses an automatic unhooking device, comprising:
[0035] The hook posture correction device 3 is used to correct the posture of the hook 1 traveling on the track 2. The rear end of the hook posture correction device 3 is provided with a disengagement device 4.
[0036] The unhooking device 4 is used to remove the product 9 from the hook 1. A sliding groove opening and closing device 5-1 is provided below the unhooking device 4.
[0037] The chute opening and closing device 5-1 is used for automatic dispensing of product 9, and to transport the dispensed product 9 to the designated position.
[0038] Among them, frame 7 is the equipment foundation, used to support unhooking device 4, upper slide 5 and lower slide 6, track 2, etc.;
[0039] Compared with the prior art, this application has the following advantages: In use, the hook posture correction device 3 first corrects the posture of the hook 1 traveling on the track 2, so that when the hook 1 reaches the unhooking device 4, the product 9 on the hook 1 is symmetrical about left and right with respect to the track 2, so that the unhooking device 4 can remove the product 9 from the hook 1. The removed product 9 falls into the slide opening and closing device 5-1, which controls the opening and closing of the upper slide 5. The slide opening and closing device 5-1 realizes the automatic distribution of the product 9 and transports the distributed product 9 to the designated position. It should be noted that, as Figure 2 As shown, hook 1 includes a hook suspension part 1-1, a hook guide part 1-2, a hook part 1-3, a product suspension part 1-3-1, a hook rod 1-4, and upper and lower limit parts 1-4-1. Hook 1 is suspended on track 2 via hook suspension part 1-1 and can slide along track 2. Product 9 is hung on hook part 1-3 of hook 1, specifically, the product is suspended at product suspension part 1-3-1. There can be two unhooking devices 4, symmetrically distributed on both sides of the frame 1, to facilitate removing product 9 from product suspension part 1-3-1 from both sides of hook 1.
[0040] Therefore, this utility model is used to automate product unhooking in equipment, replacing manual labor and solving the problems of high workload and low efficiency caused by manual labor.
[0041] Following the above embodiments, more specifically, as Figure 3 As shown, the hook posture correction device 3 includes a short angle guide plate 3-3 and a long angle guide plate 3-4, both of which are separated outward at the front end. The short angle guide plate 3-3 and the long angle guide plate 3-4 are located on both sides of the hook 1. When the hook 1 moves, the long angle guide plate 3-4 contacts the hook 1 first, and then the hook 1 enters the gap between the short angle guide plate 3-3 and the long angle guide plate 3-4 to move.
[0042] Among them, the angle between the short 3-3 angle guide plate and the long 3-4 angle guide plate, which are separated outward, should ideally be 30-60 degrees. Figure 7 As shown, when hook 1 contacts angle guide part 3-4-1 of angle guide plate length 3-4, its posture is rotated and then contacts angle guide part 3-4-1 of angle guide plate short 3-3. Then the posture of hook 1 is adjusted so that product 9 is symmetrically set on both sides of track 2, so that the unhooking device 4 can remove product 9.
[0043] Following the above embodiments, more specifically, as Figure 8As shown, it also includes a guide rod 3-1 disposed at the lower end of the hook 1 for clamping the hook 1. The guide rod 3-1 includes a guide part 3-1-1 and a limiting part 3-1-2. According to the direction of travel of the hook 1, the guide part 3-1-1 is disposed at the front end of the limiting part 3-1-2 and the guide part 3-1-1 is spread outward. Because the hook 1 is relatively long, the guide rod 3-1 is used to prevent the lower end of the hook 1 from swaying significantly from side to side when it moves, thus ensuring the posture of the hook 1.
[0044] Following the above embodiment, more specifically, it also includes upper and lower limiting rods 3-5, which are located above the hook 1 and do not contact each other. The design of the upper and lower limiting rods 3-5 prevents the hook 1 from detaching from the track 2.
[0045] The hook posture correction device 3 is suspended and fixed on the track 2 by the fixing frame 3-2. Preferably, it is connected to the frame 7 at the bottom for reinforcement. The guide rod 3-1, the short angle guide plate 3-3, the long angle guide plate 3-4, and the upper and lower limit rods 3-5 are all fixed on the fixing frame 3-2. There are two guide rods 3-1, which are set on both sides of the lower part of the hook rod 1-4. The short angle guide plate 3-3 and the long angle guide plate 3-4 are arranged opposite to each other on both sides of the hook rod 1-4. The upper and lower limit rods 3-5 are set opposite to the upper and lower limit parts 1-4-1, and a certain distance is set between them.
[0046] In other words, the upper two sides of the hook rod 1-4 are limited and guided by the short angle guide plate 3-3 and the long angle guide plate 3-4, and the lower two sides of the hook rod 1-4 are limited and guided by the guide rod 3-1. The upper and lower limit parts 1-4-1 of the hook 1 are limited by the upper and lower limit rods 3-5. When the hook 1 moves upward, the upper and lower limit rods 3-5 will block the upper and lower limit parts 1-4-1 from moving upward, thereby preventing the hook 1 from disengaging from the track 2.
[0047] Following the above embodiments, more specifically, as Figure 4 As shown, the unhooking device 4 includes a lifting device and a material-pulling device. The lifting device drives the material-pulling device to move up and down. When the material-pulling device extends or retracts, it removes the product 9 from the hook 1.
[0048] Following the above embodiment, more specifically, the lifting device includes a lifting cylinder 4-1, a base 4-2, a lifting guide rail 4-3, and a lifting frame 4-4. The lifting cylinder 4-1 is fixed on the base 4-2, and its extension rod is connected to the lifting frame 4-4. When the lifting cylinder 4-1 extends or retracts, it drives the lifting frame 4-4 to move up and down along the lifting guide rail 4-3.
[0049] Following the above embodiment, more specifically, the material feeding device includes a horizontal cylinder 4-5, a horizontal guide rail 4-6, a lever frame 4-7, and a lever 4-7-2. The horizontal cylinder 4-5 is fixed on the lifting frame 4-4, and its extension rod is connected to the lever frame 4-7. When the horizontal cylinder 4-5 extends or retracts, it drives the lever frame 4-7 to move left and right along the horizontal guide rail 4-6, and the lever frame 4-7 is connected to the lever 4-7-2.
[0050] Following the above embodiment, more specifically, it also includes a slide plate 4-7-1 for guiding the product into the slide opening and closing device 5-1, and the slide plate 4-7-1 is connected to the lever 4-7-2. Through the design of the slide plate 4-7-1, the product 9, which is removed by the lever 4-7-2, can slide through the slide plate 4-7-1 into the slide opening and closing device 5-1.
[0051] At work, such as Figure 9 , Figure 10 As shown, the lifting cylinder 4-1 can drive the lifting frame 4-4 to move up and down, which in turn drives the lever frame 4-7 to move up and down. The horizontal cylinder 4-5 can extend and retract left and right to drive the lever frame 4-7 to move left and right, thus realizing the left and right up and down movement of the lever 4-7-2.
[0052] Following the above embodiments, more specifically, as Figure 5 As shown, the slide opening and closing device 5-1 includes a left slide 5-3 and a right slide 5-4 separated by a slide partition 5-2. The left slide 5-3 and / or the right slide 5-4 are provided with opening and closing mechanisms for their opening and closing.
[0053] Following the above embodiments, more specifically, as Figure 6 As shown, the opening and closing mechanism includes an opening and closing cylinder 5-1-2 and an opening and closing plate 5-1-3 connected thereto. The opening and closing plate 5-1-3 is slidably disposed on the slide rail groove 5-3-1 of the left slide groove 5-3 and / or the right slide groove 5-4.
[0054] In one embodiment, the opening and closing cylinder 5-1-2 is mounted on the left slide 5-3 via the cylinder mounting plate 5-1-1. It is used to open and close the slide of the left slide 5-3, and to determine whether the product 9 in the slide can fall into the lower slide 6, so that the product 9 falling into the lower slide 6 can fall onto the conveyor line 8.
[0055] During operation, when the opening and closing cylinder 5-1-2 extends or retracts, it drives the opening and closing plate 5-1-3 to move on the slide rail groove 5-3-1 of the left slide groove 5-3. When the opening and closing cylinder 5-1-2 extends, the opening and closing plate 5-1-3 closes the left slide groove 5-3. Conversely, when the opening and closing cylinder 5-1-2 resets, the opening and closing plate 5-1-3 opens the left slide groove 5-3.
[0056] It should be noted that when lever 4-7-2 removes product 9 from hook 1, products 9 on both sides of hook 1 will simultaneously fall into left chute 5-3 and right chute 5-4. If neither is restrained, products 9 in left chute 5-3 and right chute 5-4 will simultaneously fall into lower chute 6, which will then transport these products 9 to conveyor line 8. However, conveyor line 8 has multiple conveyor baskets, and each basket can only hold half of the products 9 on the hook. To solve this problem, a closing plate 5-1-3 is installed in left chute 5-3. In actual operation, products 9 in right chute 5-4 are first allowed to flow into one conveyor basket. Then, according to the program time setting, the closing plate 5-1-3 is opened to allow products 9 in left chute 5-3 to flow into another conveyor basket, thus meeting actual production needs and achieving automatic material distribution.
[0057] The working process of this utility model is as follows:
[0058] Since the hook rod 1-4 can rotate freely in the horizontal direction, the posture of the hook 1 is uncertain and needs to be positioned. When the hook 1, fully loaded with products 9, is conveyed to the unhooking device 4 along the track 2, the hook guide part 1-2 of the hook 1 will first contact the angle guide part 3-4-1 of the angle guide plate 3-4. As the hook 1 continues to move backward, the guide part 1-2 will slide along the angle guide part 3-4-1 and enter the angle limiting part 3-4-2. At this time, the direction of the hook guide part 1-2 is consistent with the running direction of the hook 1, thus achieving the purpose of correcting the posture of the hook 1. During this process, the lower part of the hook rod 1-4 will also enter the limiting part 3-1-2 after passing through the guide part 3-1-1. The angle limiting part 3-4-2 and the limiting part 3-1-2 clamp the hook rod 1-4 from above and below, restricting the swing of the hook 1 in a direction perpendicular to the track 1 when unhooking.
[0059] like Figure 9As shown, before the hook 1, carrying product 9, reaches the unhooking position, the unhooking device 4 is in the waiting position. At this time, the lever 4-7-2 is below the hook part 1-3, and the minimum distance between the two levers 4-7-2 is greater than the diameter of the hook rod 1-4, with a certain safety margin, ensuring that when the hook 1 continues to move forward, the hook rod 1-4 smoothly enters between the two levers 4-7-2. When the hook 1 moves to the unhooking position, the two levers 4-7-2 have been inserted between product 9 and hook rod 1-4, with product 9 approximately in the middle position of the levers 4-7-2. At this time, the horizontal cylinder 4-5 is activated, driving the two lever brackets 4-7 on both sides to move horizontally in opposite directions, achieving the final state of levers 4-7-2. 4-7-2 disengages from the area of hook part 1-3; then the lifting cylinder 4-1 actuates, driving the lifting frame 4-4, lever bracket 4-7, etc., to move vertically upwards, reaching the final state where lever 4-7-2 disengages from the area of hook part 1-3. At this time, product 9 hanging on product suspension part 1-3-1 on hook part 1-3 will be pulled down by lever 4-7-2, and then product 9 will slide down along slide plate 4-7-1 into upper slide groove 5; hook part 1-3 and lever 4-7-2 are each divided into 3 layers, corresponding sequentially when product 9 is pulled down; the function of slide plate 4-7-1 is to prevent product 9 pulled down from the upper layer from getting caught on lever 4-7-2 below during the fall, such as Figure 10 As shown, the slide 4-7-1 has an angle in the vertical direction, causing its lower end to extend beyond the range of the lever 4-7-2 in the horizontal direction.
[0060] After product 9 falls into the upper chute 5, it will further fall into the lower chute 6 and finally onto the conveyor line 8. It should be noted that each hook 1 holds a total of 12 products 9, which are divided into two symmetrical parts of 6 products 9 each when unhooked, and slide into the lower chute 6 via the left chute 5-3 and the right chute 5-4 respectively. During packaging, approximately six products (9) are typically packed into a basket. Therefore, a chute opening and closing device (5-1) is installed at the bottom of the chute on the left side (5-3). When unhooked, the opening and closing cylinder (5-1-2) extends, and the opening and closing plate (5-1-3) blocks the chute on the left side (5-3). After the product (9) is pushed down and falls into the upper chute (5), the product (9) in the right side (5-4) will directly enter the lower chute (6) and fall onto the conveyor line (8). At this time, the conveyor line (8) will step forward a certain distance, and then the opening and closing cylinder (5-1-2) retracts, driving the opening and closing plate (5-1-3) to move and open the chute channel of the left side (5-3). The six products (9) that fell into the left side (5-3) will enter the lower chute (6) and finally fall onto the conveyor line (8), thus achieving separation of six products (9) into a group, facilitating downstream material handling and packaging.

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.
