Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of packaging machinery, especially relates to the equipment of inserting flat hook in paper card package. BACKGROUND

[0002] The card folding and pin marking machine is a kind of packaging machinery, commonly used for towel, sock, glove and other products. The basic action process is to fold the printed paper card with certain thickness and hardness as packaging material at the set position, so as to fold the rectangular paper card into U shape, then put the to-be-packaged goods into the opening of the U-shaped card, and use the glue needle gun to punch the glue needle, so as to fix the two ends of the U-shaped card and the packaged goods together. In some cases, the seller wants to hang the goods on the shelf, so a hook needs to be added to the paper card.

[0003] The hooks used in the industry are two kinds, one is called sharp hook, and the other is called flat hook. Both kinds of hooks have arc-shaped tail parts, which can be hung on the shelf. The sharp hook has a sharp head and elastic side, which can be inserted into the opening of the paper card, and then the elastic side is opened so that it will not come out of the paper card. The flat hook has a head part composed of two basically horizontal parallel strips, the tail part and the two parallel strips are integrally formed to form a sheet body, and the two parallel strips form notches on the left and right sides, so that the flat hook can be inserted into the opening of the paper card basically horizontally, and after insertion, one of the two horizontal strips is outside the paper card and the other is inside the paper card, so that the hook will not come out of the paper card.

[0004] The applicant has applied for a utility model patent named "paper card hook inserting device", with the patent number 202322799090.5. It includes a sheet-shaped hook with an acute angle head and an arc-shaped tail, a base, a containing body and a push plate. The containing body is fixedly installed on the base, and the push plate is telescopically installed on the base and is pushed by a driving mechanism. The containing body is above the push plate, and the bottom surface of the containing body is gap-fitted with the main body of the top surface of the push plate. The containing body has a through containing cavity, and a plurality of hooks are placed in the containing cavity in a stacked manner. The front end of the top surface of the push plate has a recess, the size of the recess is matched with the tail of the hook, and the depth of the recess is not greater than the thickness of the hook. When the push plate is retracted, the position of the recess corresponds to the rear part of the containing cavity. Obviously, the hook used in this device is a sharp hook.

[0005] In actual use, when the sharp head of the sharp hook is inserted into the paper card, it will touch the packaged goods, such as socks, and the burr of the sharp head may hook and damage the goods, so high-end goods tend to use flat hooks. However, there is no device in the prior art that can insert a flat hook into a paper card, and the hook insertion still relies entirely on manual operation. SUMMARY

[0025] Referring to Figure 1 The flat hook 1 is a standard part, and the whole is a sheet-shaped body, including a tail part 11 in the shape of a circular arc and a head part composed of two parallel strips 12 and 13 in the shape of horizontal strips, the tail part and the two parallel strips are integrally formed, the tail part 11 is opened at the left side, and the definitions of left and right will be used below; the two parallel strips form a notch 14 at the left side and a notch 15 at the right side. It can also be seen from the figure that the parallel strips 12 and 13 are not simple horizontal strips, but also have a certain bending.

[0026] Referring to Figure 2The sock 20 to be inserted with hooks has a paper card 2 fixed at its end, which, after being folded into a U shape, covers the front and back of the end of the sock and is fixed with a glue needle. The end face of the paper card 2, i.e. the bottom face of the U shape, has a pre-opening 25 for the insertion of the hook.

[0027] Referring to Figure 3 The embodiment includes a sock conveying and positioning mechanism 21 for conveying the sock 20 to be inserted with hooks to the specific position and fixing, which is a prior art and will not be described here. It also includes a vibrating disc 100 and a vibrating conveying track 10, the flat hooks 1 are vibrated out of the vibrating disc 100 and are conveyed one by one from the vibrating conveying track 10 in the posture of the tail 11 facing forward and the opening facing left, which are also prior arts and will not be described here. The device used in the embodiment is a D300 vibrating disc produced by Dongguan Yufeng Automation Equipment Co., Ltd. and the accompanying vibrating conveying track.

[0028] The vibrating conveying track 10 is beside a base 3, which is provided with a first arm 41 rotatably connected with the base through a first motor (not shown in the figure), the end of the first arm is provided with a second arm 42 rotatably connected with the first arm through a second motor 52, the end of the second arm is provided with a third arm 43 rotatably connected with the second arm through a third motor 53, and the end of the third arm is provided with a flat hook clamp 44 which can be opened and closed in the vertical direction through a finger cylinder (not shown in the figure).

[0029] As can be seen from the above description, the embodiment can be basically divided into three devices, i.e. the flat hook and vibrating device, the sock positioning device with the paper card, and the mechanical arm device, which can be connected or not connected physically but should not be too far apart in space so that the mechanical arm can work in the vibrating conveying track and the paper card area.

[0030] Figure 4 to Figure 8 In the middle of the figure, the flat hook 1 is too small in size and is not clear enough even after being enlarged, which can be understood by referring to Figure 1 and the textual description.

[0031] Referring to Figure 4 , Figure 1 The step 1) shown in the figure is the initial state, the first arm 41 is perpendicular to the sock conveying and positioning mechanism and parallel to the vibrating conveying track 10, which serves as the reference line of the first arm; the second arm 42 is perpendicular to the first arm 41, and the third arm 43 is perpendicular to the second arm 42, so that the flat hook clamp 44 can hold the first flat hook 1 at the front end of the vibrating conveying track. It can be seen from the figure that the paper card 2 of the last operation has been inserted with the flat hook.

[0032] Referring to Figure 5 , Figure 1Step 2) of the summary section, the first arm 41 is rotated counterclockwise to 5° with the reference line, the second arm 42 is rotated to 71° with the first arm 41, and the third arm 43 is rotated to 58° with the second arm 42. Thus, the parallel strip 12 of the flat hook 1 held by the flat hook clamp is at 18° with the end face of the paper card 2, and the flat hook 1 is close to the pre-opening 25 of the paper card, with negligible gap therebetween, i.e. the hooking preparation position as described above.

[0033] Referring to Figure 6 , Figure 1 Step 3) of the summary section, the first arm, the second arm, and the third arm are all rotated in this embodiment, wherein the first arm 41 is rotated to 3° with the reference line, the second arm 42 is rotated to 75° with the first arm 41, and the third arm 43 is rotated to 62° with the second arm 42. Thus, the parallel strip 12 of the flat hook 1 held by the flat hook clamp is at 16° with the end face of the paper card 2, and the left part of the parallel strip 12 of the flat hook 1 enters the pre-opening 25 of the paper card, with the bottom of the notch 14 contacting the paper card.

[0034] Referring to Figure 7 , Figure 1 Step 4) of the summary section, the first arm, the second arm, and the third arm are all rotated in this embodiment, wherein the first arm 41 is rotated to 18° with the reference line, the second arm 42 is rotated to 60° with the first arm 41, and the third arm 43 is rotated to 78° with the second arm 42. Thus, the parallel strip 12 of the flat hook 1 held by the flat hook clamp is at 0° with the end face of the paper card 2, and the parallel strip 12 of the flat hook 1 is entirely in the pre-opening 25 of the paper card, with only the parallel strip 13 outside the paper card.

[0035] Referring to Figure 8 , Figure 1 Step 5) of the summary section, the first arm, the second arm, and the third arm are all rotated in this embodiment, wherein the first arm 41 is rotated to 20° with the reference line, the second arm 42 is rotated to 59° with the first arm 41, and the third arm 43 is rotated to 79° with the second arm 42. Thus, the parallel strip 12 of the flat hook 1 held by the flat hook clamp is still at 0° with the end face of the paper card 2, and the parallel strip 12 of the flat hook 1 is still entirely in the pre-opening 25 of the paper card, but is translated as a whole, i.e. is translated to the right in the direction of Figure 8 , so that the bottom of the notch 15 contacts the paper card.

[0036] In Figure 6 to Figure 8In several steps of the method, all of the mechanical arms do not need to be rotated, and the purpose can also be achieved by rotating only one or two of them, but in order to achieve better results, the embodiment is designed to rotate all of the three mechanical arms, which is a better implementation. The angle parameters listed in the above are the best implementation of the utility model; all of the angle parameters ± 2° are a relatively suitable parameter range, and each step can still be well completed.

[0037] At this point, the hooking operation is completed, and each arm returns to Figure 4 the state shown in the figure, and the next cycle is started.
