JPH03256832A - Device for automatic reverse treatment of bottles - Google Patents

Abstract

PURPOSE:To permit a positioning mechanism to be changed by simple part exchange, avoid the increase of equipment costs and make operation easily adjustable by a method wherein the bottles being treated are positioned by the forward and rearward strokes of an actuator and its reverse angular adjustment. CONSTITUTION:When gripping jigs 51, 52 and 53 move from position A to position B, the left jig 51 grips a first bottle at the end of a supply conveyor 2, move back in the position A, move forward from the right position C to position D from which to transfer the bottle onto a first stand 41 of a treating device and move back with the bottle left thereon, and then to the left and back in the position A. In the meantime, the first bottle 1 is printed on the first stand 41. When these jigs move forward again, the left jig grips a second bottle and the middle jig 52 grips the bottle on the first stand and rotates through a fixed angle in the position A to turn the bottle reversely and they move in the positions C and D. Each of the gripping jigs moves while gripping the neck part of the bottle and, in addition thereto, the middle jig 52 rotates about the axis through a desired angle.

Description

[Detailed description of the invention]

(Industrial Application Field) The present invention is an automatic reversing device that is used when performing operations such as printing or pasting labels on the sides of bottles, and is particularly suitable for performing operations twice or more. Regarding.

[Conventional technology]

Various automatic devices have been developed and put into practical use to continuously print and label bottles made of glass, plastic, metal, or composite materials thereof. However, since such devices, such as curved automatic printing machines, are designed for mass production, the positioning mechanism is tailored to the processing target, and must be replaced every time the target is changed, which increases equipment costs. Not only does it take a lot of effort, it also takes time to make adjustments before starting operation. On the other hand, there is a strong demand for more sophisticated designs and detailed explanations on bottles, and printing often requires two or more processes. [Problems to be Solved by the Invention] The purpose of the present invention is to achieve both the trend toward low-volume, high-mix production and the need for complex processing, and to achieve this by reducing the positioning mechanism to a simple replacement of parts. To provide an automatic reversing processing device for bottles that can be easily adjusted during operation without increasing equipment costs. [Means for Solving the Problems] The automatic reversing processing device for bottles of the present invention sequentially arranges a large number of bottles (1) side by side, as shown in FIG. A supply conveyor (2), a processing device (4) for applying predetermined processing to at least one side of the supplied bottles, and a discharge conveyor (3) that continuously transports the treated bottles to the next process. , and a reversing mechanism (5) for reversing the bin during processing, the reversing mechanism (5) comprising an actuator (55) that moves forward and backward in the axial direction of the bin, and an actuator (55) that reciprocates in the direction of transport of the bin. It is equipped with three parallel gripping jigs (51, 52, 53) that are moved by an actuator (56), and each gripping jig can be moved by gripping the opening of the bottle. In addition, the gripping jig (52>) is characterized in that it is configured to be able to rotate the bottle by a desired angle around its axis while gripping the bottle. The mechanism is arbitrary, but if you are dealing with bottles that are particularly sensitive to scratches and stains on the surface, use one that allows you to insert the tip of the jig inside the bottle and hold it without touching the outside surface. It's good to do that.
The inventor invented and separately proposed such a mechanism, so
Please refer to it. (Function) The operation of the reversing mechanism (5) is shown sequentially by the movement of the actuator as follows.

While gripping the first bottle, the central jig (52) grips the first bottle on the first stand (41). (Go to stroke ■) Move backward and come to position A. (Stroke ■) The center jig (52) rotates by a predetermined angle, reverses the first bottle, moves to the right, and moves to position C. (Stroke ■〉 G〉) Move forward to position D and hold the central gripping jig (52).
Place the inverted bottle on the second stand (42) of the processing device, and place the second bottle gripped by the leftmost gripping jig (51) on the first stand (41). (Stroke ■〉

). wo) Release the grip on the bottle and stroke backward■),
Move to the left (stroke ■). Thereafter, in the steady state, the above strokes ① to ② are repeated. The illustrated bottle has an elliptical cross section, and the inversion is a 180° rotation to print on both the front and back sides of the bottle, but a 90' rotation can be used for bottles of other shapes, such as square cross-sectional bottles. It is also possible to print on adjacent sides. Modifications of the apparatus of the present invention include those in which two or more of the above rotating gripping jigs are provided to enable processing in three or more steps.

【Effect of the invention】

The automatic reversing processing device for bottles of the present invention can position the bottle to be processed by adjusting the forward and backward strokes of the seven cutter units and the reversing angle. All you need to do is replace the tool, and there is no need for major changes like with conventional equipment. Therefore, equipment costs are low and adjustments do not take much time. The latter effect, combined with the fact that the actuator movement follows a linear and simple trajectory, provides the benefit of reducing the overall takt time when using the device. Simple structure and operation means fewer breakdowns and easier maintenance. In this way, the apparatus of the present invention can match the requirements for high-level processing of bottles with the requirements for high-mix, low-volume production, and has a wide range of applications, particularly in the fields of cosmetics, pharmaceuticals, detergents, and the food industry. you will find out.
