Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system for continuously pumping, that is, pressurizing, raw mortar mixed and adjusted for tile joints, so-called toro.

(Conventional technology) Unlike ready-mixed concrete, the amount of toro used for tile joints per unit length of joint line is extremely small, despite the loss of freshness.
It is difficult to adapt to pouring using a hopper or chute, or transporting using a conveyor, etc. Therefore, in the past, the joint toro was prepared using a toro boat or a mixer, and then distributed on a trowel board, which was then carried in the hand. (Problem to be solved by the invention) In other words, the transportation of Toro was dependent on humans, and for this reason,
It was difficult to ensure a stable and continuous supply, which was one of the causes of low operating rates on production lines, including the jointing process. In this regard, if the transportation of Toro could be mechanized, a stable supply would be possible, and if it could be done continuously, there would be no problem. If the pump were to be pressurized and pumped, due to its high viscosity, an expensive pump would have to be custom-made, which would not be cost-effective. The present invention has been made in order to effectively solve the problems encountered in the transportation of conventional joint-use trolleys and the problems encountered when attempting to solve these problems by using a pressure-feeding method. The purpose of the present invention is to provide a tuna pumping system that can mechanize the continuous transportation of tuna at a relatively low cost. (Means for Solving the Problems) In order to achieve the above object, the present invention is configured to perform pressure feeding by intermittently pressurizing and discharging the tuna, accumulating pressure, and then delivering it. (Function) According to the above means, even if the viscosity of the toro is high, the pressurized discharge is performed intermittently, so a relatively inexpensive pump can be used, and
Since the Toro is sent out after being pressure-accumulated once, continuous transportation is possible after the delivery end. (Example) Hereinafter, an example in which the Toro pressure feeding system according to the present invention is applied to a wall panel joint filling device will be described in detail based on the attached drawings.

Check the off state (determined by the width of the wall panel Pw, that is, the number of tile rows), and if it is on. Basically, the tile size YtxXt is identified by comparing one count result with the stored data, and if it is off or several results are expected, the size is identified from the content and the two count information. It is configured to do so. Here, I will explain the function of the joint filling device Jf. From now on, in order to comprehensively describe the operating directions of members, we will introduce an orthogonal spatial coordinate system x-y-z, and the forward direction of the pallet truck Tr will be defined as the positive X-axis direction, and the forward direction of the traverse carrier Cr will be defined as the positive Y-axis direction.

The vertical joint line Jyj and the horizontal joint line Jxj switch directions. Next, the step motor Ms reverses, the trolley Tr retreats below the gate frame Fg2, the tiles Tij of the wall panel Pw are detected by the sensor Sn, and the parameter α is then determined by replacing it with β. Based on k and k°, the vertical joint line Jyj is automatically filled in the same way as the horizontal joint line Jxi, except that the subscripts of the matrix are transposed. All that is left to do is to send the pallet Pt together with the panel Pw to the next process from the rear end of the machine frame F. As a result of the test operation, extremely good results were obtained when the pressure feeding system 5 had three tube pumps, one pressure accumulation pipe, and four feeding lines. (Effects of the Invention) As is clear from the above explanation, according to the present invention, Thailand k. When transporting tuna for filling joints, first, the tuna is discharged under pressure intermittently, and the pressure is accumulated before being sent out. Therefore, the continuous transport of tuna can be mechanized at a relatively low cost. , as stable and continuous supply becomes possible.
If applied to a manufacturing line that includes a joint filling process, the line operating rate will be improved.
