Description

Technical Field

[0001] The utility model relates to the technical field of packing machines, in particular to a double-bin corner protector feeding mechanism and a strapping machine. Background Art

[0002] At present, with the continuous development of the logistics industry, before goods are transported, they usually need to be packed with packing belts. With the popularization of automatic packing technology, packing machines with automatic packing functions are widely used. During the packing process of goods, corner protectors are usually needed to cooperate with the strapping belts for packing. For placing corner protectors on the top of goods, due to the high height, the labor intensity of manually placing corner protectors is relatively large.

[0003] Chinese Patent Publication No. CN113443235A discloses a packing device with an automatic corner protector feeding function and its control method. By configuring a feeding module to store corner protectors in a storage rack and automatically supply corner protectors, and then, the supplied corner protectors are clamped by a clamping module and automatically placed at the corners of goods for strapping. However, due to the use of a single storage rack, in order to store a sufficient number of corner protectors, the overall height of the storage rack is relatively high. Chinese Patent Publication No. CN220616314U discloses a short corner protector double-bin feeding device, which adopts two bins arranged directly above a pushing mechanism, and the corner protectors in the two bins are automatically output and supplied in sequence by the pushing mechanism. In the actual use process, when the corner protectors in the first bin are used up and the feeding is switched to the second bin, since the pushing mechanism still passes through the first bin during the process of pushing the corner protectors, when filling the corner protectors, the operation of the strapping machine needs to be paused to fill the two bins with corner protectors. This will affect the continuous production and reduce the production efficiency.

[0004] In view of this, how to design a technology that can facilitate the operator to fill the corner protectors in time to meet the requirements of continuous strapping production and thus improve the production efficiency is the technical problem to be solved by the present utility model.

[0044] The present utility model will be described in detail below with reference to the accompanying drawings.

[0045] As Figures 1-8 shown, the present utility model provides a feeding mechanism for the corner guards of multiple bins, including:

[0046] Mounting bracket 1;

[0047] Storage mechanism 2, the storage mechanism 2 includes a plurality of storage racks 21, a storage tank 22 for storing corner guards is formed in the storage rack 21, and a discharge port 211 is provided at the bottom of the storage rack 21;

[0048] A plurality of pushing mechanisms 3, the pushing mechanism 3 includes a pushing driving member 31 and a pushing assembly 32, a bearing portion 321 is provided on the pushing assembly, the bearing portion 321 is configured to receive a corner guard, and the pushing driving member 31 is configured to drive the bearing portion 321 to reciprocate below the corresponding discharge port 211 along the short corner guard feeding direction;

[0049] Wherein, a plurality of the pushing mechanisms 3 are arranged side by side on the mounting bracket 1, each pushing mechanism 3 is provided with a corresponding storage rack 21, and the pushing mechanism 3 is arranged below the discharge port 211 of the corresponding storage rack 21.

[0050] Specifically, the multi-bin corner guard feeding mechanism in an embodiment of the present application is provided with a plurality of storage racks 21 for storing corner guards. Correspondingly, an independent pushing mechanism 3 is configured for each storage rack 21. In this way, during use, the corner guards in each storage rack 21 are output from the bottom discharge port 211 and fall onto the bearing portion 321 on the pushing assembly. The pushing assembly moves under the driving action of the pushing driving member 31, so that the corner guards on the bearing portion 321 are output from the bottom of the storage rack 21 to the outside, thereby realizing the supply of corner guards.

[0051] Wherein, for the pushing mechanism 3, it can meet the requirement of the discharge port 211 of the storage rack 21 to output one corner guard at a time, and can also meet the requirement of outputting the corner guards received by the bearing portion 321. For the specific structural form of the pushing mechanism 3, reference can be made to the structural configuration for pushing corner guards in the prior art, which will not be limited and elaborated here.

[0052] Since a plurality of storage racks 21 are used to store corner guards and meet the requirement of corner guard supply, when one of the storage racks 21 needs to be filled with corner guards, it can be switched to another storage rack 21 and the corresponding pushing mechanism 3 for continuous corner guard supply without stopping the machine, which is more conducive to meeting the requirements of continuous bundling and packing production.

[0053] Compared with the short corner guard double-bin feeding device disclosed in the Chinese Patent Publication No. CN220616314U in the prior art, although two bins are configured in the prior art, because the two bins need to share the same pushing mechanism 3, when the corner guards need to be filled, the pushing mechanism 3 needs to stop working, and the operator fills the corner guards into the two bins, which still cannot meet the requirement of continuous production. By configuring an independent pushing mechanism for each storage rack 21 respectively, the requirement of independent output of corner guards from different storage racks 21 can be met.

[0054] For the corner guard, its overall shape is long and strip-shaped and it has a corner structure. Depending on the different installation methods of the storage rack 21, the state of the corner guard after output is an inverted L-shaped structure or an inverted V-shaped structure. The following is a specific description in conjunction with the accompanying drawings.

[0055] As Figure 1 and Figure 2 shown, the storage rack 21 is arranged obliquely, and the storage rack 21 is configured such that the corner guard is stored in the storage slot 22 in an inverted L-shaped posture; wherein, the longitudinal section of the bearing surface of the bearing part 321 is an inverted L-shaped structure.

[0056] Specifically, for the storage rack 21, its whole is inclined towards one side. In this way, for the corner guard placed in the storage rack 21, one side part of the corner guard is in a substantially horizontal state, and the other side part of the corner guard is in a substantially vertical state. Correspondingly, for the bearing part 321, the cross-section of its bearing surface for receiving the corner guard forms an inverted L-shaped structure, so as to satisfy that the corner guard output from the discharge port 211 at the bottom of the storage rack 21 can lean against the bearing surface of the bearing part 321, thereby ensuring that the corner guard can be smoothly and reliably pushed out by the pushing component 32.

[0057] For the corner guard pushed out by the pushing component, one side part of the corner guard will overlap on the upper part of the bearing part 321, and the other side part of the corner guard will lean against the side part of the bearing part 321. Then, the corner guard can be directly clamped and placed on the goods for direct use.

[0058] Among them, for the storage rack 21, it extends obliquely from bottom to top by the pushing mechanism 3.

[0059] As Figure 3 and Figure 4 shown, the storage rack 21 is arranged vertically, and the storage rack 21 is configured such that the corner guard is stored in the storage slot 22 in an inverted V-shaped posture; wherein, the longitudinal section of the bearing surface of the bearing part 321 is an inverted V-shaped structure.

[0060] Specifically, the storage rack 21 is arranged vertically. After the corner guards are put into the storage rack 21, they are stacked upside down in sequence, so that the corner guards are arranged in an inverted V-shaped posture. Correspondingly, for the bearing part 321, the cross-section of its bearing surface for receiving the corner guard forms an inverted V-shaped structure, so as to satisfy that the corner guard output from the discharge port 211 at the bottom of the storage rack 21 can lean against the bearing surface of the bearing part 321, thereby ensuring that the corner guard can be smoothly and reliably pushed out by the pushing component 32.

[0061] For the corner guards pushed out by the pushing component, the lower surface of the corner guard abuts against the bearing surface formed by the upper surface of the bearing part 321. Since the corner guards are output in an inverted manner, after being clamped by the fixture, the corner guards can be rotated by a certain angle to adjust the posture of the corner guards to meet the requirements for placing them on the surface of the goods.

[0062] In another embodiment of the present application, the plurality of storage racks 21 are independent structures; two adjacent storage racks 21 are connected side by side, or two adjacent storage racks 21 are arranged opposite to each other.

[0063] Specifically, for the storage rack 21, each storage rack 21 can be an independent structure.

[0064] During assembly, two adjacent storage racks 21 can be connected in parallel, and two adjacent storage racks 21 are detachably connected together. For example, two adjacent storage racks 21 can be connected together by bolts or the like.

[0065] Or, as Figure 4 shown, two independent storage racks 21 are arranged opposite to each other and separated from each other.

[0066] In still another embodiment of the present application, as Figure 5 shown, the plurality of storage racks 21 are of an integral structure. The plurality of storage racks 21 together include a mounting plate 212 and a plurality of spacer plates 213. The plurality of spacer plates 213 are arranged side by side on the mounting plate 212, and a storage slot 22 is formed between two adjacent spacer plates 213.

[0067] Specifically, the plurality of storage racks 21 are integrated into an integral structure, that is, a plurality of spacer plates 213 are arranged at intervals on the mounting plate 212, and a storage slot 22 is formed between two adjacent spacer plates 213 on the mounting plate 212 to meet the storage requirements of the corner guards.

[0068] In some embodiments, in order to ensure that the loaded corner guards do not fall out of the storage slot 22, a flanging structure 214 can also be provided on the spacer plate 213. The flanging structure 214 is arranged opposite to the mounting plate 212, so that a storage slot 22 is formed between the flanging structure 214, two spacer plates 213 and the mounting plate 212 to store the corner guards, thereby preventing the corner guards from falling from one side of the storage slot 22. When the flanging structure 214 is configured, the top opening of the storage rack 21 is used for an operator to load the corner guards into the storage slot 22.

[0069] Similarly, a rotatable cover plate can also be provided on one side of the spacer 213. The cover plate can be opened and closed on one side of the storage groove 22. When it is necessary to fill the corner guard, the cover plate is selected to be opened to expose the storage groove 22, and the corner guard can be filled in place. When in use, one side of the cover plate is installed on the corresponding spacer 213 through a hinge, and the other side of the cover plate can be fixed to the adjacent partition or mounting plate 212 by fixing means such as a bolt or a pin.

[0070] Further, a plurality of the mounting notches 215 are arranged side by side at the bottom of the mounting plate 212, and the spacers 213 are respectively arranged on both sides of each mounting notch 215;

[0071] The carrying part 321 is inserted into the corresponding mounting notch 215.

[0072] Specifically, in order to meet the installation requirements of the pushing mechanism to ensure that the carrying part 321 reciprocates at the lower discharge port 211 of the storage groove 22, mounting notches 215 are provided on the mounting plate 212. The mounting notches 215 are adjacent to the discharge port 211 of the corresponding storage groove 22. The carrying part 321 is inserted into the mounting notch 215, and the corner guards in the corresponding storage groove 22 are output one by one during the reciprocating movement of the carrying part 321.

[0073] In another embodiment of the present application, for the pushing mechanism 3, refer to Figure 1 As shown, two pushing mechanisms 3 are horizontally arranged side by side on the same side, and the two carrying parts 321 are also at positions that are basically at the same horizontal height. During use, by moving the clamp horizontally back and forth, the corner guards on different carrying parts 321 can be clamped.

[0074] Or, as Figure 6 shown, two pushing mechanisms 3 are arranged vertically side by side on the same side. At this time, the storage rack 21 is generally arranged in an inclined manner. During use, after the clamp is vertically moved to the carrying part 321 at the corresponding height and then horizontally moved back and forth, the corner guards on different carrying parts 321 can be clamped.

[0075] In another embodiment of the present application, a strapping machine is provided. As Figure 7 shown, the strapping machine includes a frame 4, a packing head 5, a packing chute 6 and a clamping module 7 provided on the frame 4. The packing head 5 and the packing chute 6 form a packing area. The clamping module 7 includes a carrying rack 71, a moving mechanism 72 and a picking component 73, and further includes the multi-bin corner guard feeding mechanism. The mounting bracket 1 of the multi-bin corner guard feeding mechanism is provided on the frame 4 and arranged on one side of the clamping module 7. The picking component 73 is configured to pick up the corner guards on the carrying part 321 of the multi-bin corner guard feeding mechanism and place them on the goods to be packaged.

[0076] Specifically, the packing head 5 uses the packing chute 6 to wind the bundling tape around the goods and complete the bundling and packing process of the goods. A conventional packing machine can be adopted, which will not be restricted and elaborated here.

[0077] By configuring a multi-bin corner guard feeding mechanism on the rack 4, the storage rack 21 of the multi-bin corner guard feeding mechanism is used to supply the corner guards. After the corner guards are pushed out by the pushing mechanism 3, the moving mechanism 72 drives the picking component 73 to move to the position of the corner guards and pick up the corner guards. Then, the moving mechanism 72 drives the corner guards to move to the goods to be packed, so that the corner guards are attached to the goods and tightened on the surface of the goods by the bundling tape.

[0078] For the clamping module 7, a conventional device for automatically clamping corner guards can be adopted. Among them, the moving mechanism 72 can adopt conventional components such as cylinders or electric push rods, and the picking component 73 can adopt conventional components such as suction cups or clamping jaws, which will not be restricted here.

[0079] Among them, for the storage rack 21, a plurality of storage racks 21 can be configured on the same side of a corner position of the rack 4. Or, at least one storage rack 21 can be respectively configured on both sides of a corner position of the rack 4. Or, the multi-bin corner guard feeding mechanism can be respectively arranged on both sides of the rack 4, and the clamping module 7 matching the multi-bin corner guard feeding mechanism is also arranged on the rack 4.

[0080] Furthermore, the plurality of pushing mechanisms 3 in the multi-bin corner guard feeding mechanism are arranged side by side left and right in the horizontal direction, and the picking component 73 is configured to move along a straight line following the moving mechanism 72 to different positions to grab the corner guards pushed out by the corresponding pushing mechanisms 3. Specifically, as Figure 1 shown, two pushing mechanisms 3 are arranged side by side left and right in the horizontal direction. After the two pushing mechanisms 3 push out the corner guards, the corner guards will be located on the linear movement track where the picking component 73 is located. The moving mechanism 72 drives the picking component 73 to move to the positions of the corner guards pushed out by different pushing mechanisms 3 to pick up the corner guards.

[0081] Furthermore, the plurality of pushing mechanisms 3 in the multi-bin corner guard feeding mechanism are arranged side by side up and down in the vertical direction. A lifting mechanism (not shown) is also arranged on the moving mechanism 72, and the picking component 73 is arranged on the lifting mechanism. The picking component 73 is configured to move following the moving mechanism 72 and lift to different positions through the lifting mechanism to grab the corner guards pushed out by the corresponding pushing mechanisms 3. Specifically, as Figure 6As shown in the figure, two pushing mechanisms 3 are arranged side by side vertically. After the moving mechanism 72 drives the picking component 73 to move close to the pushing mechanism 3, the lifting mechanism is used to drive the picking component 73 to move up and down to adjust the height of the picking component 73 to meet the picking requirements of the corner guards pushed out by the pushing mechanism 3 at the corresponding height position. Then, the corner guards are picked up by the picking component 73. Among them, for the lifting mechanism, its physical manifestation can be an electric push rod, or a structure in which a motor drives a gear to rotate to drive a rack to move up and down, which is not limited here.

[0082] Furthermore, the two relatively arranged pushing mechanisms 3 in the multi-bin corner guard feeding mechanism are located on the same straight line, and the picking component 73 is configured to move along a straight line to the same position following the moving mechanism to grab the corner guards pushed out by the corresponding pushing mechanism. Specifically, as Figure 4 shown in the figure, the two pushing mechanisms 3 are located at the same height and are relatively arranged horizontally. The two pushing mechanisms 3 can push the corner guards to the straight-line movement trajectory where the picking component 73 is located, so that the picking component 73 can move to the same position to pick up the corner guards pushed out by one of the pushing mechanisms 3.

[0083] A double-bin corner guard feeding mechanism and a bundling machine provided by the present invention arrange a plurality of storage racks side by side on the mounting bracket, and each storage rack is correspondingly provided with an independent pushing mechanism for feeding. During actual use, when the corner guards in one of the storage racks are used up, other storage racks with corner guards can be switched to continue supplying corner guards through the corresponding pushing mechanisms. And the operator can timely replenish the corner guards in the storage rack when the bundling machine is not shut down. By arranging a plurality of storage racks side by side and correspondingly configuring corresponding pushing mechanisms, it is realized that the filling of corner guards in different storage racks does not affect each other, which is convenient for the operator to timely fill the corner guards to meet the requirements of continuous bundling production and thus improve production efficiency.
