Description

Improved structure of clamping jaw of article selecting and vending machine

Technical Field

The utility model relates to a clamping jaw structure of an article selecting vending machine; in particular to a technology for improving the structure of a clamping jaw and increasing the contact length or area of articles clamped by the clamping jaw.

Background

A plurality of commodities are placed in the space of the transparent cabinet, and a person operates a rocker to control the crown block host to move so as to drive the clamping jaw to clamp the commodities, which belongs to the prior art; for example, taiwan patent nos. 94208053 entitled "article selection vending machine" and 105208502 entitled "improved structure of doll catching machine" provide typical examples.

FIG. 1 shows a prior art jaw configuration; comprises a cylinder A, in which components such as a motor, a spring, a valve rod (not shown) and the like are arranged for driving a plurality of clamping jaws B arranged outside the cylinder A to generate folding or unfolding motion. The clamping jaw B is of a slightly arched structure and is provided with a base C and an arm D; the arm D is of a smooth flat structure and has two inclined edges E. The clamping jaw B is connected with the tail ends of the two bevel edges E to form a structure of a large-curvature bent edge F, so that when the clamping jaw B grabs a commodity, a point contact type is easily formed, and the commodity is easily dropped.

To enhance consumer interest and willingness, the prior art discloses a number of devices for increasing the chances of the jaws grasping an article. For example, taiwan patent No. 107217466, "grip pawl cover of article selecting and vending machine", applies silica gel material to make an envelope structure, which is sleeved on the grip pawl arm to increase the friction force or the blocking force of the grip pawl and prevent the goods from slipping from the grip pawl; or Taiwan patent No. 107205530 "" gripper "", in which the end of the gripper is divided into a fork structure, and a shaft rod is installed in cooperation with the fork structure to pivotally connect a clamping member with anti-slip effect.

The old method also discloses the application of a special operation interface, which is matched with the assistance of direction or light beams to increase the probability of the clamping jaws for grabbing commodities; for example, taiwan patent nos. 106216019 entitled "article selection vending machine gripper positioning light beam aiming device" and 106215979 entitled "article selection vending machine gripper orientation adjusting device" provide practical embodiments.

One problem with the above jaw arrangements or the like in manufacturing applications is that they are often additionally provided with auxiliary means; such as the clamping claw sleeve, the clamping piece, the operation interface combination direction adjusting device, the positioning light beam aiming device and the like. As is known to those skilled in the art, this increases the cost of manufacture and assembly, as well as making the structure more complex; which is not desirable.

Representatively, these references show the design skill in structure and manufacture with respect to the existing jaw structure or the like; they also reflect some of the problems with these jaw configurations or the like. If the clamping jaw structure is re-designed and considered, the technology of assembling auxiliary structures or devices additionally by the old method is removed, so that the clamping jaw structure is different from the prior art, and the structural form of the clamping jaw structure can be improved and is different from the old method; in essence, under the condition of meeting the requirement of improving the probability of successfully grabbing goods by the clamping jaw, the conditions of higher manufacturing and assembling cost, more complex structure and the like in the prior art are improved. None of these issues are taught or specifically disclosed in the above references.

Detailed Description

Referring to fig. 2, 3 and 4, the improved structure of the clamping jaw of the vending machine for selecting items of the present invention includes a clamping jaw 10 pivotally connected to a cylindrical body 90; the cylindrical body 90 is provided therein with components such as a motor, a spring, a valve rod, etc., which constitute a driving device for controlling the plurality of clamping jaws 10 disposed outside the cylindrical body 90 to generate folding or unfolding motion; the driving device is well known in the art and therefore not described in detail.

In the illustrated embodiment, the jaws 10 are slightly arcuate in configuration, and may be designed as straight rods, arcuate rods, or other configurations that achieve the desired combination of article gripping. The jaw 10 has a base 15 and an arm 16 connected to the base 15; the base portion 15 and the arm portion 16 define a reference axis χ.

The arms 16 are shown on either side along a reference axis χ extending obliquely in an expanded configuration towards the ends of the arms 16 to form a first section 11 and a second section 12 connecting the first section 11. A first included angle alpha is formed between the second section 12 and the first section 11; the first included angle alpha is an obtuse angle larger than 120 degrees, or the first included angle alpha is equal to 180 degrees.

And, the arm 16 further comprises a third section 13 connected to the second section 12; the third section 13 extends towards the direction of the reference axis x and is intersected and jointed, and a second included angle beta is formed between the third section 13 and the second section 12; the angle of the second included angle beta is between 70 and 120 degrees, so that the third section 13 forms a straight line or a small-curvature arc structure close to the straight line, the contact length or area of the arm part 16 (tail end) to the clamped article 80 is increased, and the probability of successfully clamping the article 80 is relatively increased; meanwhile, the situation of higher manufacturing and assembling cost in the prior art is improved.

It can be understood that the first section 11, the second section 12 and the first included angle α are matched with the second section 12, the third section 13 and the second included angle β, so that the third section 13 forms a relatively straight structural configuration, and the contact area or the contact length between the arm 16 and the object 80 is increased; such as the situation depicted in fig. 4. And, the third section 13 may be formed in a straight configuration or a slightly arcuate configuration to assist in increasing the contact area or length between the arm 16 and the article 80.

Typically, the improved jaw structure of the vending machine includes the following advantages and considerations over the older methods:

1. the structure and connection of the clamping jaws 10 have been redesigned; for example, the arm 16 has a first section 11 and a second section 12 to form a first included angle α, and a second included angle β is formed by matching the second section 12 and the third section 13; the third section 13 is a linear or arc line structure, which is different from the existing structure type and is different from the old method.

2. In particular, the jaw 10 construction eliminates the technique of otherwise assembling ancillary structures or devices; moreover, under the condition of meeting the requirement of improving the commodity grabbing probability of the clamping jaw, the situations of higher manufacturing and assembling cost, more complex structure and the like in the prior art are improved.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
