Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machine accessories, and in particular to a packaging rotary feeding tray. Background Technology
[0002] Rotary feeding mechanisms are widely used in automated packaging equipment. By using a rotary drive to move the clamping arm back and forth between the feeding position and the winding position, they enable rapid and precise transfer or redirection of materials, thereby improving production efficiency and reducing manual intervention. Traditional rotary feeding mechanisms typically employ a rotating disk combined with a gripper structure.
[0003] Figure 1 The diagram illustrates a gripper in an existing rotary feeding mechanism, where the top and front ends of the gripping surface 3 are both acute angles. Because the feeding accuracy of the robotic arm is affected by temperature and humidity, resulting in a certain deviation angle, when a packaging box is inserted into the gripper, the lack of a reasonable guiding structure in the insertion direction of the gripping surface 3 can easily lead to the packaging box getting stuck or mispositioned, affecting the success rate of feeding. Utility Model Content
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A packaging rotary feeder includes a plurality of grippers arranged circumferentially on a rotating disk. Each pair of adjacent grippers cooperates to fix a packaging box. Each gripper has a non-intersecting, wedge-shaped clamping surface on both sides. The clamping surface is used to engage with and fix the packaging box. The clamping surface is provided with at least one guide structure in the direction of entry and exit of the packaging box.
[0006] Furthermore, the direction of entry and exit is the front end of the clamping surface, and the guiding structure is a front guide surface disposed at the front end of the clamping surface.
[0007] Furthermore, the angle between the front guide surface and the clamping surface is 50°.
[0008] Furthermore, the direction of entry and exit is the top end of the clamping surface, and the guiding structure is a top guide surface disposed at the top end of the clamping surface.
[0009] Furthermore, the angle between the top guide surface and the clamping surface ranges from 50° to 65°.
[0010] Furthermore, guide grooves are provided on the top of each of the grippers, and the guide grooves are arc-shaped so that the guide grooves together form a virtual circumference.
[0011] Furthermore, it also includes mounting grooves formed on the rotating disk that match the base of the gripper.
[0012] Furthermore, a rear stop surface is also provided at the rear end of the clamping surface.
[0013] The beneficial effects of this utility model are as follows:
[0014] The present invention provides a packaging rotary feeding tray with a guide slope to improve the smoothness of packaging box insertion, while optimizing the gripper assembly and adding an auxiliary guide structure to improve the rotational stability of the rotating tray.

The above description is for the purpose of simplifying the description of this utility model and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0023] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the relevant listed items.
[0024] In the specification, when an element is described as being "on," "fixed" to, "connected" to, or "joined" to another element, the element may be directly located on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element present.

[0025] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.
[0026] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.
[0027] Figure 2 The overall structure of this rotating packaging tray is shown, including several grippers 20 mounted on a rotating disk 10. The grippers 20 must be used in pairs. A packaging box (not shown) is moved into and / or out of the grippers 20 by a robotic arm from the front and / or top. The packaging box rotates with the rotating disk 10 while being placed into the grippers 20, allowing it to quickly turn from one station to the next. Since the driving method of the rotating disk 10 and the robotic arm used to move the packaging box are prior art and do not relate to the inventive points of this technical solution, they will not affect the implementation of this technical solution and will not be described in detail in this utility model application.
[0028] In one embodiment, in order to enable the gripper 20 to be quickly assembled onto the rotating disk 10 by the fastener 30, a corresponding mounting groove 11 is provided on the rotating disk 10, and the mounting groove 11 and the base 21 correspond to and match each other.
[0029] Figure 3 and Figure 4The overall structure of the gripper is shown. The gripper 20 has a base 21 for connecting to the rotating disk 10 and a claw portion 22 located at the front end for engaging with adjacent grippers 20 to hold the packaging box. The claw portion 22 has a first gripping surface 23a and a second gripping surface 23b on its two opposing sides. The front ends of the first gripping surface 23a and the second gripping surface 23b are respectively provided with a first front guide surface 24a and a second front guide surface 24b. The first front guide surface 24a and the first gripping surface 24a extend outwards, changing the shape of the original acute angle at the opening (the same applies to the second gripping surface 23b and the second front guide surface 24b), making it easier for the packaging box to be inserted between the grippers 20 from the front end. The top ends of the first clamping surface 23a and the second clamping surface 23b are respectively provided with a first top guide surface 25a and a second top guide surface 25b. Similarly, the first top guide surface 25a and the first clamping surface 23a (and the second clamping surface 23b and the second top guide surface 25b are also extended outwards.)
[0030] Reference Figure 5 and Figure 6 The first clamping surface 23a and the second clamping surface 23b are arranged in a wedge shape (viewed from the top), such that the first clamping surface 23a and the second clamping surface 23b or the second clamping surface 23b and the first clamping surface 23a of each pair of adjacent grippers 20 are parallel to each other, so that the packaging box can be inserted into and clamped from the front end and / or the top end. Correspondingly, a first rear end stop surface 26a and a second rear end stop surface 26b are provided at the rear end of the first clamping surface 23a and the second clamping surface 23b to limit the insertion depth of the packaging box from front to back.
[0031] In a preferred embodiment, the angle 24c between the virtual extension surface of the first front guide surface 24a and the first clamping surface 23a is 50°, and the angle between the second front guide surface 24b and the second clamping surface 23b is also 50°.
[0032] In another preferred embodiment, the angle 25c between the virtual extension surface of the first top guide surface 25a and the first clamping surface 23a is 50° to 65°, and the angle between the second top guide surface 25b and the second clamping surface 23b is also within the range of 50° to 65°. This angle selection, combined with the precision of the robotic arm, improves the error tolerance and increases the success rate of placing the packaging box.
[0033] Furthermore, an arc-shaped guide groove 27 can be provided on the top surface of the claw part 22. Several guide grooves 27 arranged with the claw 20 form a virtual circle in space. Together with the external guide rail, they ensure that the movement trajectory of the rotating disk 10 is also circular, thereby improving rotational stability.
