Technical Field

[0001] The utility model belongs to the field of nut packaging, and particularly relates to a bag-taking device for nut packaging. Background Art

[0002] Nuts are a classification of indehiscent fruits with a hard pericarp and containing one or more seeds. Nuts are the essence of plants, generally rich in nutrition, containing high levels of protein, fat, minerals, and vitamins, and have excellent effects on human growth and development, enhancing physical fitness, and preventing diseases. When processing nuts, the last step is to bag the nuts for subsequent packaging.

[0003] When quantitatively packaging nuts, a bag-taking device can be used to send packaging bags to the packaging machine one by one and in an orderly manner for quantitative filling. The existing bag-taking devices are generally clamping hands or robotic arms. Although they can also complete the bag-taking of packaging bags well, the structures of clamping hands or robotic arms are relatively complex and expensive. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the present utility model is to provide a bag-taking device for nut packaging, aiming to solve the problems of relatively complex structure and high price of the existing bag-taking devices.

[0005] The present utility model adopts the following technical solutions:

[0006] The bag-taking device includes a bag-holding rack and a bag-taking mechanism arranged adjacent to each other front and back, and the bottom of the bag-holding rack is inclined towards the bag-taking mechanism. The bag-taking mechanism includes a bag-taking table. A fixed seat and a support seat are respectively arranged in front of and behind the bag-taking table. A bag-taking arm is rotatably arranged on the outside of the fixed seat. A bag-taking rod is rotatably arranged on the bag-taking arm. A bearing block is rotatably arranged on the support seat. A support rod is rotatably arranged downward on the bearing block, and the bottom of the support rod is connected to the tail of the bag-taking rod. Sections are opened on both sides of the bag-taking rod, and a through short groove is opened between the sections. A suction cup is arranged in the short groove through a pair of upper and lower nuts. A bag-taking cylinder for driving the bag-taking arm to rotate is also arranged on the bag-taking table.

[0007] Further, a bag-blocking plate is arranged at the bottom of the bag-holding rack. A bag-taking opening is opened on the bag-blocking plate. A pair of upper blocking edges and a pair of bag-blocking blocks are respectively arranged on the front and back sides of the bag-blocking plate corresponding to the bag-taking opening.

[0008] Further, a buffer seat is arranged on the side wall of the bag-taking table. A buffer sleeve is arranged on the buffer seat. A buffer column is arranged at the top of the buffer sleeve.

[0009] Further, a buffer pad is arranged at the end of the bag-taking rod, and the buffer pad corresponds to the bottom end face of the bag-holding rack.

[0010] Furthermore, the middle part of the bag-taking arm is a hollow structure.

[0011] The beneficial effects of the present utility model are as follows: When taking the bag, the bag-taking cylinder drives the bag-taking arm to rotate clockwise. The bag-taking arm drives the bag-taking rod to rotate towards the bag-putting rack until the suction cup adsorbs the position of the packaging bag at the lowest layer. After the suction cup adsorbs the packaging bag, the bag-taking cylinder drives the bag-taking arm to rotate in the reverse direction until the bag-taking rod returns to its original position. At this time, the packaging bag is placed horizontally waiting to be transferred. Description of the Drawings

[0015] In order to make the patent purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0017] For the convenience of description, only the parts related to the embodiments of the present utility model are shown.

[0018] Combined with Figure 1-2 As shown, the bag-taking device includes a bag-putting rack 1 and a bag-taking mechanism arranged adjacent to each other front and back. The bottom of the bag-putting rack 1 is inclined towards the bag-taking mechanism. The bag-taking mechanism includes a bag-taking table 2. A fixed seat 3 and a support seat 4 are respectively arranged in front of and behind the bag-taking table 2. A bag-taking arm 5 is rotatably arranged outside the fixed seat 3. A bag-taking rod 6 is rotatably arranged on the bag-taking arm 5. A bearing block 7 is rotatably arranged on the support seat 4. A support rod 8 is rotatably arranged downward on the bearing block 7. The bottom of the support rod 8 is connected to the tail of the bag-taking rod 6. Sections are opened on both sides of the bag-taking rod 6. A through short groove 9 is opened between the sections. A suction cup 10 is arranged in the short groove 9 through a pair of upper and lower nuts (not shown in the figure). A bag-taking cylinder 11 for driving the rotation of the bag-taking arm 5 is also arranged on the bag-taking table 2.

[0019] After nuts are processed in the factory, in order to extend the shelf life and freshness period of nuts, facilitate collection, and better meet the needs and usage of consumers at different levels, after a series of processing, a certain quantity of nuts will be sealed and packaged in a packaging bag.

[0020] When quantitatively packaging nuts, this bag-taking device can be used to send packaging bags to the packaging machine one by one and in an orderly manner, and the packaging machine is used to achieve the quantitative packaging of nuts. In actual situations, there is a bag-clamping mechanism on the packaging machine.

[0021] Before the bag-taking action is performed using this device, the staff needs to place the stack of packaging bags in the bag-putting rack as required. When taking the bag, the bag-taking cylinder drives the bag-taking arm to rotate clockwise, and the bag-taking arm drives the bag-taking rod to rotate towards the bag-putting rack until the suction cup adsorbs the position of the lowest-layer packaging bag. After the suction cup adsorbs the packaging bag, the bag-taking cylinder drives the bag-taking arm to rotate in the reverse direction until the bag-taking rod returns to its original position. At this time, the packaging bag is placed horizontally, and the bag-clamping mechanism on the packaging machine clamps the current packaging bag and moves it to the packaging position. And the bag-clamping mechanism is not the key content of this device, so it will not be described in detail here.

[0022] This device can drive the bag-taking arm to rotate and drive the suction cup to complete the bag-taking action only by using the bag-clamping cylinder. Compared with using grippers or robotic arms, the structure of this device is relatively simple, and the manufacturing cost is also quite low.

[0023] In the embodiment, the number of the suction cups is two, and the bag-taking action is completed by two suction cups, which can effectively improve the stability during the entire bag-taking process. And the suction cup is a double-layer bellows suction cup. Generally, from top to bottom, the double-layer bellows suction cup is a vacuum port connecting pipe 101 and a bellows suction cup 102 in sequence. A connecting thread is formed on the outer wall of the vacuum port connecting pipe, and the top end of the vacuum port connecting pipe is connected to a vacuum pipe (not shown in the figure). And the suction cup is installed in the short groove by a pair of upper and lower nuts. In actual situations, the distance between the two suction cups can be finely adjusted. When adjusting the installation position of the suction cup, only need to loosen any one of the nuts. At this time, the vacuum port connecting pipe can slide along the length direction of the short groove to adjust the installation position. After determining its installation position, tighten the nut, and the suction cup is firmly installed in the short groove.

[0024] As a preferred structure, a buffer seat 12 is provided on the side wall of the bag-taking table 2, a buffer sleeve 13 is provided on the buffer seat 12, and a buffer column 14 is provided at the top of the buffer sleeve 13, and the buffer column passes through the buffer seat. A buffer pad 14 is provided at the end of the bag-taking rod 6, and the buffer pad 14 corresponds to the bottom end face of the bag-putting rack 1.

[0025] When using the suction cup to adsorb the packaging bag, the bag-taking cylinder drives the bag-taking arm to rotate towards the bag-putting rack, and the buffer pad rotates towards the bag-putting rack synchronously until the buffer pad contacts the bag-putting rack. The buffer pad plays a role in limiting the bag-taking rod, ensuring that the suction cup can stably adsorb the packaging bag at the bottom layer. At the same time, the buffer pad also plays a role in buffering and shock absorption.

[0026] When the buffer pad contacts the bag-putting rack, the suction cup adsorbs the packaging bag. The bag-taking cylinder drives the bag-taking arm to rotate in the reverse direction until the bottom of the bag-taking arm contacts the buffer column. At this time, the packaging bag is in a horizontal position. During this process, the buffer column plays a role in limiting and shock absorption.

[0027] Furthermore, as a preferred structure, as Figure 3 , a bag-blocking plate 15 is provided at the bottom of the bag-putting rack 1. A bag-taking opening 16 is formed on the bag-blocking plate 15. A pair of upper blocking edges 17 and a pair of bag-blocking blocks 18 are respectively provided on the front and rear sides of the bag-blocking plate 15 corresponding to the bag-taking opening.

[0028] In this embodiment, the bag-blocking plate plays a role in blocking the packaging bag. A pair of upper blocking edges and a pair of bag-blocking blocks are respectively provided on the front and rear sides of the bag-blocking plate. The front end of the upper blocking edge is bent towards the inside, which is convenient for the stacked packaging bags to slide towards the bag-blocking plate. The upper blocking edge plays a role in blocking and limiting the packaging bag. At the same time, the two bag-blocking blocks are respectively located on the left and right sides of the bag-blocking plate and are arranged in an inverted V shape. With the mutual cooperation of the bag-blocking blocks and the upper blocking blocks, the packaging bag can be prevented from naturally falling to the ground from the bag-taking opening.

[0029] In addition, the middle part of the bag-taking arm 5 is of a hollow structure. This can reduce the weight of the bag-taking arm, enabling the bag-taking cylinder to easily drive the bag-taking arm to rotate.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
